Description

The The invention first relates to a washing machine according to the Preamble of claim 1.

Especially, but not exclusively, the invention relates to a Washing machine for use in the commercial sector. Such commercial washing machines are made for quite some time and are used in particular the Cleaning of professional clothing, such as overalls and trousers subjected to heavy soiling, such as work clothing in the butchery or butcher industry, bakery clothing, Fire department clothing etc.

It are known a number of detergents that are in adaptation to special Requirements when washing soiled textiles special Contain active ingredients. In particular, it is known, depending on the application, special enzymes, special surfactants, special bleaches, special odorants, special solvents etc. provided.

Also In commercial washing machines, however, it is not foreseeable in advance, what kind of soiling the textiles to be cleaned have. adjustments are therefore both in terms of the degree of contamination, as well with regard to the nature of the pollution and the nature of the required to be cleaned textiles.

The The invention also relates to washing machines Kind of a conventional household washing machine. Such Washing machines are typically used in every household and have compact, sometimes even standardized dimensions and dimensions on. A household washing machine represents a closed component, which only has a water connection and a power supply line requires, but not special supply lines.

The The object of the invention is one assumed to be known Washing machine according to the preamble of the claim 1 further develop such that at high washing efficiency, the environmental impact is reduced.

The Invention solves this problem with the features of the claim 1, in particular with those of the characterizing part, and is accordingly characterized characterized in that a plurality of containers provided is, in which different active ingredients for mixing a drug combination arranged are, and that a control device is provided by Selection of a program via the program selector dosing devices appeals to the different containers are to one in the nature or condition of the objects and / or the type of soiling and / or a particular wash cycle adapted active ingredient combination of the different active ingredients in a mixing chamber separate from the receiving chamber, wherein the control device is a supply line of the active ingredient combination into the receiving chamber only after completion of the drug combination caused in the mixing chamber.

The Principle of the invention thus consists essentially in spatial Assignment to the washing machine to arrange several containers. In The containers are arranged different active ingredients, to a drug combination, for. B. to a detergent, composed can be.

When possible, suitable active ingredients are, for example different enzymes and / or different surfactants provided. Also come different enzyme mixtures or different Surfactant mixtures in question.

equally come as active ingredients complexing agents, bleaches, preservatives, Solvent, odors, corrosive agents, etc. in question.

Nearly all ingredients of conventional detergents or conventional laundry additives can be used in the separate containers are arranged and by appropriate dosing be dosed individually. By Selection of a washing program at a program selector switch on the Washing machine, the user can take into account which textiles or textile textiles to be cleaned and what kind or degree of contamination is. Of the Program selector switch or one in operative connection with this Control device can then the corresponding metering devices, the For example, via signal control lines with the Washing machine are connected, address. The dosing devices can the individual agents z. B. according to one electronically filed table in accordance with dose the selected washing program and over supply a common supply line to the mixing chamber. The mixing chamber is arranged separately from the receiving chamber, that is, it has a separate supply line connected to the receiving chamber and is preferably, at least slightly spaced from the receiving chamber.

The mixing chamber allows the achievement of a completely homogeneous mixture of the active ingredient combination of the individual active ingredients. For example, in the mixing chamber, a conventional heavy duty detergent, colored laundry detergent, prewash detergent or the like may be mixed together.

First after completion of the detergent or other active ingredient combination, for example, an optical brightener, or a bleach, or equipment, for example for protection of fire-fighter clothing against damage by high temperatures, can mix and assemble in the mixing chamber Drug combination are fed to the receiving chamber. The containers communicate communicatively with the mixing chamber, that is, that it is a pipe, a hose, a screw conveyor od. The like. Is that the containers together or separately connects with the mixing chamber and a supply of the active ingredients towards the mixing chamber. The connection is switchable, that is via the metering device or over additional separate valves or switching arrangements can the metered dosing of the drug causes or prevented. Any can do this suitable conveyors, such as pumps, be arranged.

Thereby, that the individual active ingredients, so to speak as a concentrate, separated and arranged separately in containers and individually dosed can be an optimized combination of active ingredients with regard to the desired application, z. As a detergent to be assembled. While Conventional detergents try a particularly wide range of applications to provide, and a particularly extensive Containing a mixture of different active ingredients that virtually everyone Purpose, that is, every possible degree of contamination, every kind of pollution and any texture covers the objects to be cleaned, according to the invention a variable composition of the detergent on site, in or on the Washing machine done.

To the others can do this by using concentrates of active ingredients the transport and packaging costs are significantly reduced become. Use conventional liquid detergents For example, water contents of more than 80%. at the washing machine according to the invention can be a Mixing the active ingredients of the detergent with water only during or after the supply of the active ingredients into the mixing chamber. The water is available locally, as the washing machine anyway connected to a water pipe.

Thereby, that the high water content common with liquid detergents are, eliminated, the transport or packaging costs to be reduced by up to 70 to 80%.

A Mixture of the active ingredients together to provide a combination of active ingredients, in particular a detergent, takes place in one of the receiving chamber upstream mixing chamber. When a household washing machine is the mixing chamber is preferably arranged directly on the washing machine. In a commercial washing machine, the mixing chamber may also be spaced be arranged from the receiving chamber.

additionally may optionally already have a premix in the supply line between the individual containers and the mixing chamber done what usually not considered disturbing.

When Receiving chamber in the sense of the present patent application is for the case of a washing machine, in particular a commercial washing machine or a household washing machine, in particular a conventional, understood rotating drum. In the case of a cleaning device is understood as a receptacle, the tub, the detergent or detergent for carrying out the washing process receives the objects to be cleaned.

Thereby, that depending on the choice of wash program a different, special Composition of the active ingredient combination, for. B. the detergent, can be reached, the sewage pollution can be low being held. Since only the active ingredients are used, the washing program as selected by the user for essential, the waters are not dispensable with Detergent ingredients loaded.

The Mixture of the individual active ingredients for the production of a detergent in the mixing chamber on site, ie in the washing machine or at least close The washing machine is also beneficial, considering that in conventional detergents, not any active ingredients mix with each other. Thus, the Applicant recognized that For example, in liquid detergents or others certain conventional, liquid detergents Active ingredients can settle, so they finished in the conventionally prepared agents are not homogeneously distributed are. Also, the Applicant has observed that certain agents can react chemically with each other, if this in a conventional Detergents are mixed together.

Due to the separate and separate storage of the individual active ingredients in individual containers according to the present invention and by the single-dose mixing together of the active ingredients only in the mixing chamber, during washing or just before washing, such settling problems and unwanted chemi reactions between the individual active substances are avoided. The active ingredients are first mixed in the mixing chamber and are used immediately after completion of the combination of active ingredients in the receiving chamber, without any adverse effect in terms of their effectiveness chemical reaction.

the Applicant is aware of a washing machine of the prior art, when the washing machine with different containers is in switchable communicative connection, being in the containers different detergents are arranged. It makes a difference However, the washing machine according to the invention by that detergent active ingredients, that is components of a detergent, can be mixed together to form a detergent. When Detergents are especially enzymes, surfactants, complexing agents etc. viewed.

When Active substance combination in the sense of the present patent application any mixture of at least two, preferably three, different Active ingredients or active ingredient ingredients or drug combinations considered. The active ingredients or active ingredients are initially separated from each other the different containers assigned and can individually metered fed to the mixing chamber become. There, especially with the help of water, a Solution or emulsion mixed together, the desired Formulation with an appropriate quantitative, volume or percentage ratio of the individual Contains active ingredients. Only after completion of the desired Active ingredient combination is the drug combination from the mixing chamber deflated and fed to the receiving chamber.

From the US 4,503,575 a washing machine is known in which a mixing tank is connected via two lines to the washing drum. Additives can be introduced into the mixing tank in the desired amount via a solenoid valve control. For this purpose, however, the mixing tank must first be emptied by a certain amount of water beforehand, since the solenoid valve can only be closed again after an opening when a sensor determines that the mixing tank is again completely filled. The prescribed mixing container is not suitable for mixing desired drug combinations in the manner according to the invention, since whenever two or more active ingredients are to be mixed together, already an amount of active ingredient of the corresponding amount of water from the mixing tank is discharged into the receiving drum before the Solenoid valve for a second additive is opened. In particular, when numerous different active ingredients are used, the desired composition of the active ingredients in the mixing chamber is not predictable, since always parts of the drug or drug combinations, possibly also unwanted drug combinations are drained via the emptying process from the mixing tank into the receiving chamber, before the drug combination is completed. This can lead to undesirable and also to the objects to be cleaned adverse chemical reactions and milieus in the receiving drum. To make matters worse, that for the purpose of flushing the metering devices in the washing machine according to the invention also large amounts of water are used. When using a mixing tank, as in the publication described above, this can lead, for example when mixing a drug combination of ten different active ingredients, that more than 90% of the water contained in the mixing tank at the beginning of a mixing process with dissolved active ingredients and drug combinations in nine steps would be, before all the drugs needed to complete the desired drug combination would be included in the mixing chamber.

When Active substance combination in the sense of the present patent application in particular a colored laundry detergent, a pre-wash, a bleach with an optical brightener, a washing power amplifier, a Absäurer, a mold conditioner containing starch, any Washing additive product of at least two active ingredients, etc. understood. In particular, the combination of active substances within the meaning of the present Patent application any combination of at least two, preferably three, more preferably four, more preferably at least five understood different agents. The arrangement of a separate Mixing chamber makes it possible to achieve a particularly homogeneous Mixture of a drug combination and also an improved emulsification the individual substances.

Further Advantageously, the mixing chamber is assigned a mixing device, in particular with the aid of a motor drive for Further optimization of the mixing of the active ingredients ensures. This may in particular be a mechanical stirring aid or the like, to a vibration mixing device or, for example to act a swirling device.

According to an advantageous embodiment of the invention, the mixing chamber is arranged at a distance from the receiving chamber. This embodiment has the advantage that the mixing chamber can be arranged close to the metering devices. Furthermore, the mixing chamber is connected to the receiving chamber via a drain line. The mixed in the mixing chamber and finished Asked drug combination can be fed through the drain line of the receiving chamber. As a result of promoting the combination of active ingredients through the drain line, further homogenization and mixing of the active ingredient combination can be achieved.

According to one Another advantageous embodiment of the invention is the mixing chamber arranged adjacent to the metering devices. this makes possible a particularly advantageous structural design of the washing machine insofar as that the metering with the mixing chamber under Circumstances can be combined to form a unit. Also, the ways that are part of the dosable agents too have to cover the mixing chamber on this Way to keep it very low. Especially when dosing agents deliver in small quantities metered, the z. B. only a few milligrams weigh, and flushing devices are provided during the or rinse the dosing device after each dosing operation, to prevent drug residues or residues the metering device remain, is a close or immediate adjacent arrangement of the mixing chamber to the metering advantageous, since the risk increases with active ingredients in small doses, that these agents on their way to the mixing chamber to unwanted To adhere to places.

For example the metering devices can also be so with the mixing chamber interact that the respective dosage of an active ingredient falls directly into the mixing chamber.

According to one Another advantageous embodiment of the invention, the mixing chamber and the controller disposed in or on the washing machine. Mixing chamber and control device are as far as integral Components of the washing machine trained. The control device can be one of a conventional control of a conventional Washing machine be separate control device, or with a known, conventional control of a washing machine interact or even part of a common control device or be associated with such.

According to one Another advantageous embodiment of the invention is the mixing chamber connected to the receiving chamber via only one outlet. This is a simple design in terms of design the invention possible.

According to one Another advantageous embodiment of the invention is the outlet assigned a responsive by the controller valve. The Valve can open or lock the outlet pipe and in this way ensure with a high degree of certainty that the mixing chamber is in communicative communication with the receiving chamber stands or this connection is interrupted.

According to one Further advantageous embodiment of the invention, the control device ensures that the valve until the completion of the drug combination remains closed in the mixing chamber. This ensures that the drug combination until its final Completion and achievement of a homogenous mixing in the mixing chamber remains and only after completion in the receiving chamber is directed.

According to one Further advantageous embodiment of the invention, the control device ensures that the valve after completion of the drug combination in the mixing chamber transferred to its open position becomes. The valve can remain in the open position as long as until the mixing chamber is completely empty. In an advantageous manner Way, the controller provides for a complete emptying the mixing chamber making sure that the valve is below again is closed, so during a wash program the mixing chamber hermetically sealed or at least from the receiving chamber is fluidically separated. Alternatively, this one Valve during a washing process but also open stay, especially if additional wash water is fed through the mixing chamber through the receiving chamber or the mixing chamber is to be rinsed with wash water.

According to one further advantageous embodiment of the invention prevents the Control device that active ingredients before completion of the drug combination get into the receiving chamber in the mixing chamber. In this way can the drug combination in a very precise predetermined Be mixed together. At the same time it can be prevented that adverse consequences arise from unwanted Active ingredients or unwanted drug combinations of Receiving chamber are fed.

The control device can address the metering device for dispensing the desired metered quantity via a control command. This is particularly advantageous if the metering devices are assigned a control command receiving device. The control device is connected to the metering devices insofar via a signal line or control line. The control command addresses the metering devices, and gives, for example via a time information, an indication of how long the metering device is to remain open to deliver the respective active substance, for which period of time a metering device pump for a release of Active substances from the appropriate container should provide, etc.

Accordingly the control command can provide information about the metered quantity of the respective active ingredient.

Further advantageous is the respective dosage of an active ingredient of an arithmetic unit of the control device over a period of time and a metering rate of the metering device calculable.

These Embodiments offer the advantage that the metering devices can be addressed directly by the control unit, in order to obtain a certain active ingredient in a desired dosage leave. It does not require that via a switch detected a liquid level in the mixing chamber is, which shuts off the metering device. The metering device is over a desired dose amount corresponding time duration command driven.

According to one Another advantageous embodiment of the invention is a flushing device provided after or at delivery of the metered amount of active ingredient causes a flushing of the metering device. Especially for very small amounts of active ingredients is such a flush beneficial to drug residues, in an undesirable manner could adhere to the metering device, the mixing chamber with high security.

The The invention solves the above-described problem further with the features of claim 15, in particular with those of Marked part, and is accordingly characterized that a plurality of containers is provided in which different active ingredients for mixing a drug combination are arranged, and that a control device is provided, by selecting a program via the program selector switch Dosing devices that respond to the different containers are assigned to the type or nature of the items and / or on the type of contamination and / or on a particular wash cycle adapted active ingredient combination of the different active ingredients in a particular of the receiving chamber separate mixing chamber composed, wherein the mixing chamber to achieve a homogeneous mixing the active ingredients in the mixing chamber associated with a mixing device is.

at the washing machine according to the invention is a mixing chamber, in particular a separate from the receiving chamber mixing chamber provided in the combination of active ingredients of the different Active ingredients is mixed together. For a particularly homogeneous mixing Achieving the active ingredients in the mixing chamber is a mixing device intended. This mixing device is assigned to the mixing chamber, that means in or at or in the immediate vicinity the mixing chamber arranged. The mixing device is in particular motor driven, and for example in the manner of a stirrer or Blender trained.

Accordingly is z. B. a rotating element, for. B. a wing element, provided, which within the mixing chamber, by a motor Drive driven, rotated, and the drug combination homogenized. The individual active ingredients are, together with the one in the mixing chamber Water, whirls, mixes, leaving a particularly homogeneous Active ingredient combination is achieved. Also an improved emulsification is possible in this way.

Next Motor-driven mixing devices come as mixing devices Also such devices in question, for example, by generating of vibrations for the desired mixing to care. Also, turbulators may be provided be due to flow vortex for the desired homogenization of the active ingredients provide. For example can as swirling a special, nozzle-shaped Inlet be provided to the mixing chamber, through the water below Pressure is introduced into the mixing chamber at high speed and there makes for a swirling.

Also other, suitable mixing devices, for example with the aid of of pressure wave or ultrasonic wave generation for the desired homogenization of the drug combination to care.

According to one advantageous embodiment of the invention is the mixing device assigned a drive. Such a drive ensures that contained in the mixing chamber volume of water and drug combination in motion, in vibration or in rotation.

Especially It is advantageous that several active ingredients of the mixing chamber at the same time zuleitbar, since in this way a particularly homogeneous mixing the active ingredients is possible.

Furthermore, it is advantageous if different, in each case in the mixing chamber successively mixed together drug combinations of the receiving chamber are successively zuleitbar. This can allow a time-delayed and optimized for the wash program addition of different individual drug combinations. Different washing steps during a wash program, for example, even at different temperatures are performed. According to the invention certain drug combinations, for. As enzyme mixtures are supplied at certain temperatures and thus optimized. Due to the individual dosage of the individual drug combinations, a further optimization of the washing efficiency can be carried out.

Advantageous are the active ingredients as concentrates in the containers arranged. As a concentrate in particular a drug nature or the nature of an active ingredient combination, in the water or the filler content kept low are or are almost completely avoided. conventional Liquid detergents have water contents from partly to to 80%. Conventional powder detergents have very high percentages of fillers containing no active ingredient represent a detergent, but only the consistency of the detergent influence. On these additives, only as carriers may be present to provide a conventional detergent Almost completely dispensed with according to the invention.

According to one advantageous embodiment of the invention is in a first container a first enzyme as active ingredient and in a second container a second, different enzyme arranged as an active ingredient. A Splitting the detergent components into different enzymes and the ability to dose these enzymes individually, enables an optimized washing efficiency. So can For example, lipases can be used to break down fats, and For example, professional clothing, such as in a slaughterhouse accumulates, optimally clean. Amylases should be at the Cleaning of fats soiled clothing, at least at some use cases, but not needed become. By choosing a suitable wash program, z. B. with the Title "Cleaning of greasy professional clothing", could be done according to a control that the Enzyme amylase is omitted or only slightly dosed and the enzyme Lipase is added in high doses to the detergent.

alternative For example, when cleaning baker's clothing, where to expect that here are very strong impurities of textiles Flour, that is to say starch, can be found, amylase as Enzyme can be added in high doses, while lipases are practical not needed.

While currently in conventional detergents z. B. four different Enzymes, namely proteases, amylases, lipases and cellulases, can be used, that in the future even more Separate enzymes can be used for further optimization. According to the number of reasonably separable enzymes should be a corresponding Number of containers for the different ones Enzyme be provided.

Under Circumstances also comes a common container for a first enzyme mixture and another separate one Container for another, second enzyme mixture into consideration.

equally can advantageously be a first container for a first type of surfactant and another container for a second type of surfactant may be provided. By providing different, individually dosable surfactants can adapt to different Pollutions are also optimized. There is also the possibility For example, for allergy sufferers without enzymes or without certain surfactants to carry out the washing programs.

From The advantage is that multiple drug combinations within one Washing program or within a washing process in succession the receiving chamber can be supplied. different Active substance combinations can themselves have different pH values have, especially if they are already in liquid form available. Alternatively, the drug combinations in the washing liquid in the receiving chamber different pH values unfold. You can make sure that in the receiving chamber washing liquid to a certain time and for a certain duration one certain pH, which changes during the wash program. Taking into account a particularly suitable pH may be the drug combinations or possibly also Additives have a particularly beneficial effect and the to wash objects to be washed particularly efficient or to treat.

Especially can during a wash program first first pH a, subsequently during the program another pH value b and finally, if necessary, a third one pH c can be achieved. Thus, the mode of action of the active ingredients and the drug combinations are significantly improved. Also can in the manner of the invention agents are used, which are not used conventionally could, as in the prior art only washed alkaline. For example can according to the invention a washing program first start in an acidic environment, then in one alkaline d. H. basic environment with same or with others Active ingredients and drug combinations are continued and finally towards the end again in an acidic environment be terminated.

For example, wool materials easily acidified after completion of the washing process taken out of the receiving chamber who so that an impregnation or a flame retardant coating or the like can be applied in a particularly simple manner, for example, because the adhesion has been improved. Other advantageously designed washes with a single or multiple change in pH are possible.

The in connection with the subjects of the claims 1 and 15 described advantages exist equally or analogously in connection with the objects of the claims 36, 40, 54, 59, 60 and 61.

Same or similar parts or elements are in the following Description of the figures, as far as different embodiments are affected, sometimes denoted by the same reference numerals, and partly with the addition of small letters.

evidenced 1 has a substantially conventionally designed commercial washing machine 10 a receiving chamber 11 which is typically formed by a rotating drum and can be closed door-like by a closure glass, not shown. A program selector 12 is indicated and used for the manual adjustment of a specific program by the operator. Other program selectors, for example, the nature of the textiles to be cleaned, the type and degree of contamination may be on the washing machine 10 be provided, but are in 1 not shown.

The outline of the 1 shows that the washing machine 10 via a supply line 13 with different containers 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h connected is. From the central supply line 13 therefore go corresponding branches 17a . 17b . 17c . 17d . 17e . 17f . 17g . 17h to the appropriate containers.

Equally, an electronic control line 14 provided, which is also denominatable as a signal line and also with the individual containers 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h connected is. Again, go from the signal line 14 corresponding branches 18a . 18b . 18c . 18d . 18e . 18f . 18g . 18h from.

First, it should be noted that the architecture of both the supply line 13 as well as the signal line 14 is purely schematic to understand. For example, it may alternatively be provided a star connection, which, starting from the washing machine 10 to every container 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h a separate control line 14 and a separate supply line 13 runs. It can also be provided that the supply line 13 at the in 1 aborted shown end connected to a water pipe. This water pipe can also feed the washing machine to carry out a washing process. Alternatively, from any container 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h a separate water supply takes place. The water flowing in the water pipes can also bring about a transport of the active ingredients, and entrain these active ingredients, for example, in the water flow or, dissolved therein, take along.

Finally, the control line can 14 , as shown, be equipped with branches. Alternatively, from the washing machine, or from the central, electronic control unit 71 the washing machine, to every container 15a . 15b . 15c . 15d . 15e . 15f . 15g . 15h separate control lines run.

The container 15a is, schematically in 1 shown, a metering device 16 , z. As a conventional metering pump assigned. The control line 14 connects the controller 71 of the washing machine 10 over the junction 18a with the metering device 16 , In the container 15a is a first enzyme, for example, lipase E ₁ , arranged. By selecting a suitable washing program with the program selector switch 12 For example, it can be set to dissolve greasy soiling. The metering device 16 receives from the controller 71 of the washing machine 10 therefore, at an optimized time during the wash program, instructing a certain amount of lipase E ₁ from the container 15a in the corresponding feeder branch 17a the supply line 13 contribute.

Corresponding metering devices 16 are also on the other containers 15b . 15c . 15d . 15e . 15f . 15g . 15h arranged, for reasons of clarity but not shown.

In the container 15b there is an enzyme E ₂ , for example cellulase. Another enzyme E ₃ is in the container 15c , for example, amylase. Finally, there is an enzyme E ₄ , z. B. protease, in the container 15d ,

Proteases primarily cleave proteins and act against soiling, such as spinach and the like. Amylases split strength and counteract Mashed potatoes, chocolate, pudding and the like. Lipases split fats and act against salad oil, dripping, sunscreen, make-up and the like. Cellulase removes cotton fluff and refreshes colored fabrics. By individual dosing of the different four enzymes E ₁ , E ₂ , E ₃ , E ₄ can thus be optimally adapted to the pollution production of a detergent, without bringing unnecessary agents into the detergent and pollute the waste water unduly, but at the same time the required Active ingredients can be used in sufficient quantities.

The containers 15e . 15f contain different surfactants T ₁ and T ₂ , or different surfactant mixtures. This is intended merely to illustrate, by way of example, that it is advantageously possible to also provide different containers for different surfactants. The number of containers or the number of different surfactants or surfactant mixtures depends on the extent to which individual dosability of the detergent active ingredients is desired.

The container 15g serves to accommodate a complexing agent K. Also, the complexing agent can be controlled by the washing machine 10 be metered depending on the choice of the washing program.

The container shown by way of example 15h serves to accommodate, for example, a solvent or a complexing agent or an anti-corrosive agent or a bleaching agent, od. Like. Also, in 1 not shown containers can be provided. It is also possible to mix individual active ingredients, for example surfactants, with complexing agents, etc. It is important that the active ingredients are present in concentrate form, without emulsifiers, preservatives and carriers, such as fillers or water, stabilizers, etc. mixed or mixed in excessive amounts.

The washing machine 10 according to 1 includes a mixing chamber 70 that the receiving chamber 11 or washing drum 11 upstream and is arranged separately from this. The mixing chamber 70 connects the receiving chamber 11 with the supply line 13 , In the embodiment of the 1 is the mixing chamber inside the washing machine 10 arranged, which in particular in a still to be explained household washing machine according to 3 is of particular advantage. However, according to a commercial washing machine 1 the mixing chamber 70 basically also outside the envelope of the washing machine 10 be arranged.

The individual active ingredients, for. As the different surfactants or surfactant mixtures and the different enzymes or enzyme mixtures are according to their dosage by the metering devices 16 over the supply line 13 first of the mixing chamber 70 fed. There they are mixed together to form the desired active substance combination with the corresponding active ingredient proportions. Only after complete mixing of the desired drug combination with the desired water content is a valve 76 opened, showing the mixing chamber 70 with the receiving chamber 11 combines. After opening the valve, the contents of the mixing chamber 70 completely in the receiving chamber 11 be emptied.

The valve 76 is this via a signal line branch 77 with the control unit 71 connected. The control unit 71 sets as described above, via control commands the metering devices 16 in action and can also determine so far or expect for a given period of time that at some point the completion of drug combination in the mixing chamber 70 is finished and then a corresponding command to open the valve 76 to generate.

1 also shows that the program selector switch 12 via a dashed line branch 75 is connected to the control unit and in this respect the control unit 71 can appeal.

1 only provides a control unit 71 However, it will be clear to the person skilled in the art that several control units can also be provided. Furthermore, the control unit 71 that addresses the dosing pumps and the valve 76 may be formed by a conventional control unit of a conventional washing machine, which has been extended or supplemented accordingly. Alternatively, the control unit 71 also be a separate control unit.

In 1 is the sake of clarity, the line branch of the supply line 13 that is inside the washing machine 10 runs, with 72 designated.

The mixing chamber 70 allows the completion of the desired drug combination in a very homogeneously mixed manner and a supply of the finished drug combination only after their completion in the receiving chamber. The control unit 71 ensures that the valve 76 remains closed until the drug combination in the mixing chamber 70 is completed and a derivative of the mixed detergent or the desired product in the receiving chamber 11 only then takes place when the desired mixture has been achieved.

1 merely indicates a metering device 16 in the associated container 15a at. However, it is clear to the person skilled in the art that each container is preferably assigned its own metering device.

1 also indicates a flushing device 100 on, that of the metering device 16 is adjacent. In particular, in the event that very small volumes of active ingredient, as is the case with enzymes, are discharged, and the supply line 13 In principle, there is the risk that residues of active substance or small amounts of active substance undesirably adhere to constituents of the metering device. By attaching a flushing device 100 , which is shown only schematically, and may be provided with a separate water supply, for example, but it is possible to flush the metering device or its flushable components after each drug discharge, so as to ensure that the entire, small volume drug amount of the mixing chamber 70 can be supplied.

Furthermore, with regard to 1 noted that the mixing chamber 70 the metering devices 16 may also be arranged immediately adjacent, which is particularly advantageous because the delivery routes can be kept very low.

evidenced 2 assigns 1 alternatively constructed container 15a four chambers 19a . 19b . 19c . 19d on. Here, the enzymes E ₁ , E ₂ , E ₃ , E ₄ are arranged in the individual chambers, which should be illustrated by different levels of filling. The dosing device also shown only schematically 16 is able to access the individual chambers 19a . 19b . 19c . 19d to act separately and to dose the individual enzymes E ₁ , E ₂ , E ₃ , E ₄ individually. Alternatively, four separate metering devices can be provided. The container 15a here has four separate containers in the sense of the patent application.

When Active substances within the meaning of the present patent application are under Other enzymes and surfactants, but also mixtures thereof. Under The term drug combination or drug mixture also fall any mixtures of active ingredients with additives such as Solvents, complexing agents, bleaching agents, anti-corrosives, Fillers, stabilizers and water. It should be noted that certain active ingredients or drug mixtures provide their optimal cleansing soil-solubilizing or functional effect advantageously reach in a certain alkaline or acidic environment.

With the washing machine and cleaning device according to the invention can be ensured that individual drug combinations during a washing program successively in the receiving chamber be supplied. In this case, the drug combinations within a wash program at different times and at different pH values of the in the receiving chamber located Wash water or wash solution act.

Different Expressed, the pH of the washing liquid during a wash program change. The change The pH value can be directly from the active ingredients or from Drug mixtures are caused or alternatively by separate Additives added to the active substances or mixtures of active substances are, or which are supplied separately.

So For example, you can make sure that at the beginning a wash program, a first drug combination passed into the receiving chamber and because of its chemical properties there for an alkaline environment, or containing additives, which provide an alkaline environment. The additives If necessary, they can also be obtained from a separate container be supplied.

below, advantageously only after expiration of a period of time during the drug combination has its optimal effect, can another drug combination introduced into the receiving chamber be at the same time the pH in a predetermined manner in the acidic environment changes.

following can z. B. a third drug combination or the aforementioned first drug combination are added and again for a change of the washing water milieu towards the alkaline.

On This can be the textiles or objects to be cleaned or the active ingredients or active ingredient combinations during be exposed to different pH levels of a wash program, whereby an optimal effect of the individual active ingredients are achieved can.

The construction unit 67 includes four containers 68a . 68b . 68c and 68d in which different active substances or active substance mixtures are contained. A metering device 16 Analogously to the dosing devices described above, the active ingredients can be metered individually, in the mixing chamber 70 mix and over the common supply line 66 the device 64 respectively. At any point, the supply line 66 For example, with a water pipe in communicative connection, so that in the containers 68a . 68b . 68c and 68d stored active ingredients can be stored as a concentrate and diluted with water to a washing liquid.

With regard to the nature of the usable active ingredients for the containers of the assembly 67 The considerations made above on the other embodiments of washing machines and cleaning devices apply analogously.

Based on 10 will now be exemplary and exemplary of the construction of a mixing chamber 70 with an associated separate mixing device 80 to be discribed. This description should be sent to the mixer 80 , Valves 76 or, as in 10 shown, two valves 85a and 85b , Can be arranged in all the previously described embodiments of the figures, ie in washing machines, cleaning devices and dishwashers.

A mixing device 80 serves for optimized homogenization of a drug combination or drug mixture in the mixing chamber 70 , The mixing device 80 can in particular a motor drive 81 exhibit. evidenced 10 drives the drive 81 a wave 82 on, the, under sealing of sealants 101 , in the interior of the mixing chamber 70 protrudes. There are rotatably on the shaft 82 wing 84a . 84b . 84c . 84d arranged. In the embodiment of the 10 a four-bladed arrangement is provided, wherein the two pairs of wings axially in the longitudinal direction of the shaft 82 spaced apart from each other. The number and arrangement of the wings is freely adaptable.

By rotation of the shaft 82 around its longitudinal axis is the arrangement of the wings 84a . 84b . 84c . 84d set in rotation and a mechanical rotation of the in the mixing chamber 70 achieved liquid volume achieved. The liquid is vortexed and stirred so that the individual components or active ingredients are homogeneously mixed in the desired manner.

10 In addition, it can be seen that a first valve 85a the mixing chamber 70 from the supply line 86 can separate. The supply line 86 leads, What 10 does not show due to the aborted representation, depending on the location to the individual containers 15a . 15b . 15c . 15d respectively. 23a . 23b . 23c . 23d respectively. 68a . 68b . 68c . 68d respectively. 56a . 56b . 56c . 56d respectively. 48a . 48b . 48c . 48d ,

The valve 85a is how alike the shut-off valve 85b from the in 10 not shown control unit 71 addressable and connected via a signal line, not shown, with this. The valves 85a and 85b are openable and lockable.

At the beginning of a process for mixing an active ingredient combination is the valve 85a z. B. in an open position, while the valve 85b in a locked position. About the supply line 86 can the individual active ingredients, together with water, over the supply section 87 and through the inlet 89 through the mixing chamber 70 be supplied. During feeding, the valve is 85b closed so that over the supply section 88 , the outlet 91 and the other, downstream of the valve 85b arranged line section 89 no active ingredient and no liquid to the receiving chamber 11 or a reception basin 40 or a rinsing chamber 52 can be supplied.

Now the valve can 85a be closed by the controller, and start the mixing or mixing process. This is the drive 81 addressed by the controller via a separate signal line and activated, for example, over a predetermined period of time. After sufficient mixing, the valve can 85b be opened via the control line from the control unit and the mixing chamber 70 be emptied. The drug combination is in this way the receiving chamber 11 , or the rinsing chamber 52 or the receiving basin 40 supplied accordingly. In this way it is achieved that a particularly homogeneously mixed active ingredient combination only after its completion reaches the receiving chamber.

Alternative active mixing devices can create vibrations or turbulences in the interior of the mixing chamber. Thus, for example, it can be thought of water under high pressure via an inlet opening in such a way into the interior of the mixing chamber 70 bring in that here by vortexing the desired mixing is achieved. However, it should be noted here that foaming should be avoided as far as possible, as this could preclude a homogenization of the drug combination. Other active mixing devices, which are not shown, and which provide, for example, with the aid of pressure waves for the desired mixing, are conceivable. Finally, rotating drums can be used. It could also be the housing wall of the mixing chamber 70 be rotated and in this way that in the mixing chamber 70 take along the liquid volume. Also means for shaking the mixing chamber 70 are suitable as a mixing device.

mixers 80 and control devices 71 and valves 76 . 85a . 85b Although not the figures of the embodiments show some of the washing machines, cleaning devices and dishwashers according to the 1 to 9 be used and arranged.

The above-described washing machines, dishwashers and cleaning devices all have at least one mixing chamber 70 and preferably also a mixing device 80 on. The mixing chamber is also preferably used to homogeneously mix drug combinations from different active ingredients. Under certain circumstances, it is also conceivable that a mixing chamber present in a washing machine 70 is used to mix a single active ingredient particularly homogeneously with water, for example, if such an agent is particularly viscous or poorly water-soluble.
