Thereby air heated by the heating element 8 in the conduit 7 for the supply air is applied by means of the fan 14 to wet textiles contained in the rotating drum 4 . In the drum 4 the heated air is charged with moisture. The air charged with moisture arrives by means of the conduit 9 for the exhausted air at the heat exchanger 10 which is cooled with the fan 15 . Water condenses in the heat exchanger 10 and is collected in the sump 11 . The pump 12 pumps the water of the sump 11 into the condensate collector 13 .

According to the method at least one action for protection of an operator of the domestic appliance (1) is taken when an interruption of an active program for treating textiles with hot steam occurs. The method shall prevent that the operator is hurt by the hot steam generated in the domestic appliance. The domestic appliance (1) comprises a control (40) and a memory (41) storing at least one program for treating textiles with steam, wherein the control (40) is adjusted to execute the inventive method.
Description
- The invention concerns a method for operating a domestic appliance and a domestic appliance, especially a home dryer or a washing machine,
- Home dryers and washing machines are well known in the state of the art. In relation to home dryers it is thereby known to dry textiles using a condensation process or using a wet exhausting air process.
- It has been found out that the treatment of textiles can be improved by using steam which is applied to the textiles e.g. in a dryer during one operation mode of the dryer. One aspect of such a process is to prepare the textiles in a better way for the following ironing. Another aspect is to remove unwanted odours out of the textiles.
- The dryer comprises as a rule a rotatable drum in which the textiles are contained when the textiles are treated with hot water steam. The steam generated by a steam unit is conducted by a conduit and a steam injector into the drum. The steam has, during the operation in the drum normally a temperature of equal or more than 100° C. Opening the door used for loading and un-loading the drum of the dryer with textiles during the run of a program for treating textiles with steam can-therefore be dangerously for an operator.
- It is therefore an object of the present invention to propose a method for operating a domestic appliance and a domestic appliance as mentioned above which at least reduce the risk of an accident with hot steam during the operation of the domestic appliance.
- This object is inventively achieved by the method for operating a domestic appliance, especially a home dryer or a washing machine, of claim 1, which domestic appliance comprises a steam unit and an operating mode for treating textiles with hot steam, wherein at least one action for protection of an operator of the domestic appliance is taken when an interruption of an active program for treating textiles with hot steam occurs. The inventors have recognized that every interruption of a program for treating textiles with steam should be supervised because independently thereof whether the interruption was caused by the operator or not there is always potentially the danger that the operator opens the door of the domestic appliance without thinking about the hot steam inside the domestic appliance. It is therefore reasonable to provide at least one preferably more actions that the operator is not hurt by the hot steam generated in the domestic appliance, when an interruption of a run of a program for treating textiles with hot steam occurs.
- According to one variant of the invention the action is taken, when a door for loading and un-loading a room of the domestic appliance with textiles is opened, whereby the opening of the door interrupts the program for treating the textiles with steam. Normally the domestic appliance has a door to a rotatable drum containing the textiles during the operation of the domestic appliance. The door comprises a mechanism for opening and closing the door. It is proposed to have sensing means working together with the mechanism for opening and closing the door. Preferably the sensing means are connected with control means of the domestic appliance. The control means finally initiate the action for the protection of the operator, when the door is opened during a run of a program for treating the textiles with steam.
- According to another variant of the invention the action is taken, when the program for treating textiles with steam is interrupted by activation of a switching equipment of the domestic appliance. The switching equipment comprises preferred a stop-button or a start/rest-button. Theses buttons are as a rule part of a operating panel of the domestic appliance. The switching equipment can also be a kind of virtual button e.g. a button displayed on a screen e.g. displayed on a touch screen.
- The action is also taken, when the run of the program for treating textiles with steam is interrupted by a failure of the domestic appliance. Such a failure can be e.g. a short interruption of the supply voltage of the domestic appliance which can cause the interruption of the run of the program for treating textiles with steam.
- A preferred action is to release at least one warning signal to the operator which calls the operator's attention to the hot steam inside the domestic appliance especially inside the drum. The warning signal can be an acoustic and/or an optical warning signal. When the warning signal is an optical warning signal it is preferred displayed with an optical display, which comprises a lamp or a LED-display (light emitting diode) or the operating panel of the domestic appliance, which operating panel comprises particularly a LCD-display (liquid crystal display).
- Another action for protection of an operator is to stop at least partially the supply of steam to the room, particularly to the drum of the domestic appliance containing the textiles, when an interruption of a run of a program for treating textiles with steam occurs. Thereby the control means of the domestic appliance stop as a rule the activity of the steam unit, in particular the activity of the pump of the steam unit and/or the heating of the steam generator.
- According to variants of the invention the supply of steam to the room of the domestic appliance containing the textiles can be at least partially stopped by closing a conduit which is used for supplying the room with steam. The conduit can thereby be closed by a valve, preferred by a magnetic valve.
- Another possibility according to the invention to protect an operator is to deplete the steam unit of the domestic appliance of steam at least partially, when an interruption of a run of a program for treating textiles with steam occurs. This can be achieved by a valve, preferred a magnetic valve. Preferably the opening and closing of the valve is controlled by the control of the domestic appliance. The steam is thereby conducted in a part or in parts of the domestic appliance to which the operator has as a rule no contact or no access.
- According to embodiments of the invention the supply of steam to the room of the domestic appliance containing the textiles can be at least partially stopped by the reversion of the flux of the steam through the steam unit. By a reversion of the flux of the steam through the steam unit thus the steam do not flow through a conduit and an injector in direction to the room containing the textiles but flows in the opposite direction. Preferred the pump of the steam unit which normally pumps water out of a water tank into the steam generator of the steam unit is thereby operated in a reversed mode. In the reversed mode the pump of the steam unit is operated in an opposite direction and pumps the steam already generated in the steam generator into the water tank.
- It is also possible for the protection of the operator to conduct the steam contained in the drum of the domestic appliance out of the drum, when an interruption of a run of a program for treating textiles with steam occurs. This can be achieved by a separate conduit connected with one side to the drum and with the other side e. g. to the outside of the domestic appliance. Preferably there is a controllable valve for opening the passage through the conduit. Advantageously a fan is used for conducting the steam out of the drum containing the textiles. Another possibility for conducting the steam out of the drum of the domestic appliance is to use an already existing conduit of the domestic appliance. Preferred is the use of the conduit of the supply air to the drum and/or the use of the conduit of the exhaust air out of the drum. Both conduits are normally used for air circulation during the process of drying textiles. The last mentioned embodiment is therefore particularly adapted for home dryers.
- According to an embodiment of the invention the door for loading and un-loading the domestic appliance with textiles can not be opened after an interruption of an active program for treating textiles with steam until there is no more danger for an injury of an operator. Preferred the door for loading and un-loading the domestic appliance with textiles can not be opened for a certain period of time and/or until the temperature and/or the atmospheric moisture in the room of the domestic appliance containing the textiles has/have a certain value. The opening of the door is in these cases thus either time controlled or temperature controlled or atmospheric moisture controlled.
- The domestic appliance can be in case of a dryer a dryer of the condensation type or a dryer of the exhaust air type.
- The domestic appliance according to the invention comprises a control and a memory storing at least one program for treating textiles with steam, wherein
- the control is adjusted to execute at least one of the aforementioned methods.
- Embodiments of the invention are illustrated in the accompanying schematic drawings. It is shown:
-
FIG. 1 a dryer in a front view, -
FIG. 2 a first embodiment of components of the dryer ofFIG. 1 , partially shown in a schematic block diagram and -
FIG. 3 a second embodiment of components of the dryer ofFIG. 1 , partially shown in a schematic block diagram. - The invention is consecutively exemplarily described for a domestic appliance in form of a home dryer. But the domestic appliance according to the invention can also be a washing machine comprising a steam unit as described later and an operating mode for treating textiles with steam.
-
FIG. 1 shows a front view of a dryer, especially a home dryer 1.FIG. 2 shows in one embodiment of the invention components of the home dryer 1 ofFIG. 1 . The home dryer 1 ofFIG. 1 andFIG. 2 is a condensation type dryer. The home dryer 1 comprises ahousing 2 with adoor 3 for loading and un-loading a drum 4 with not shown textiles. The drum 4 is rotatable around an axis A by means of a motor 5 and abelt 6. The drum 4 is in a not shown way respectively pivoted. - For drying textiles the home dryer 1 comprises a
conduit 7 for the supply air to the drum 4, aheating element 8 in case of the on hand embodiment arranged in or near theconduit 7 for the supply air, aconduit 9 for the exhausted air, a heat exchanger 10, a sump 11, apump 12, a water tank or condensate collector 13, afirst fan 14 in case of the on hand embodiment arranged in theconduit 7 for the supply air and a second fan 15 arranged near the heat exchanger 10. Thefirst fan 14 and the second fan 15 are connected to a drive motor 16. - Further the home dryer 1 comprises an
operating panel 30 with andisplay 31 and a turningknob 32 for choosing a program for drying textiles and/or a program for treating textiles with steam. The operatingpanel 30 is connected to control means in form of acontrol 40 of the home dryer 1. Thecontrol 40 is preferably a program driven computer and comprises amemory 41. A plurality of different programs for drying textiles and programs for treating textiles with steam is stored in thememory 41 which can be chosen with the turningknob 32. Thedisplay 31 is preferably a LCD-display. Thedisplay 31 is particularly intended for displaying program information and operating data of the home dryer 1. Theknob 32 and thedisplay 31 can also be used for setting operating parameters of the home dryer 1. - In one operation mode of the home dryer 1, when a program for drying textiles is chosen by an operator with the turning
knob 32 of the operatingpanel 30 the home dryer 1 is operated in an air circulation mode. Thereby air heated by theheating element 8 in theconduit 7 for the supply air is applied by means of thefan 14 to wet textiles contained in the rotating drum 4. In the drum 4 the heated air is charged with moisture. The air charged with moisture arrives by means of theconduit 9 for the exhausted air at the heat exchanger 10 which is cooled with the fan 15. Water condenses in the heat exchanger 10 and is collected in the sump 11. Thepump 12 pumps the water of the sump 11 into the condensate collector 13. Now the air is again heated and conducted by means of thefan 14 into the drum 4. This air circulation process continues until the textiles in the drum 4 are dried in an adequate manner. The run of the chosen program for drying textiles is controlled by thecontrol 40 of the home dryer 1 which is particularly connected to the motor 5, theheating element 8, the motor 16 and thepump 12 what is not explicitly shown inFIG. 2 . - In another operation mode of the home dryer 1 textiles contained in the drum 4 can be treated with hot water steam. The home dryer 1 comprises therefore a steam unit. The steam unit comprises a
water tank 20, a pump 21, asteam generator 22 and ainjector 23 for the steam connected to thesteam generator 22 by aconduit 24. As described above the operator can choose a program for treating textiles with steam with the turningknob 32. During the run of such a program water contained in thewater tank 20 is pumped by the pump 21 into thesteam generator 22 and there heated. The steam generated in thesteam generator 22 arrives by means of theconduit 24 and theinjector 23 at the drum 4. The hot water steam is then applied to the textiles contained in the drum 4, which thereby rotates around the axis A. The hot water steam has a temperature of 100° C. and more. This process particularly the run of the respective program is again controlled by thecontrol 40. - Especially during the run of a program for treating textiles with hot steam the danger exists that an operator is hurt by the hot steam when an active program is interrupted. Normally an interruption of a run of program for treating textiles with steam is caused either by opening the
door 3 for loading and unloading the drum 4 with textiles or by switching of a switching equipment of the home dryer 1. But an interruption of a run of a program for treating textiles with steam can also occur in consequence of a failure of the home dryer 1. By the way this listing is not concluding. - For detecting the opening of the
door 3 for loading and unloading the drum 4 with textiles as soon as possible amechanism 17 for opening and closing thedoor 3 is equipped with additional sensing means 18. The sensing means 18 are e. g. a light barrier or any other appropriate sensor for registering at once the opening of thedoor 3 with themechanism 17. The sensing means 18 are connected to the control 40 (not shown in the drawings). Therefore thecontrol 40 can at once register when thedoor 3 is opened. - As mentioned above the run of a program for treating textiles with steam can also be interrupted by the activation of switching means. Switching means for such an interruption are in the case of the on hand embodiment a stop-
button 33 and/or a start/rest-button 34 of the operatingpanel 30 of the home dryer 1. The switching of any of these buttons is registered by thecontrol 40. - In any case of interruption of a run of a program for treating textiles with steam, especially in the aforementioned cases, it is reasonable to take at least one action for protection of the operator. It is namely possible that the operator is not aware of the hot steam inside the drum 4 when the interruption occurs.
- When the
control 40 registers an interruption of a run of a program for treating textiles with steam is it by means of the sensing means 18 or by getting a stop signal or rest signal based on the activation of the stop-button 33 or of the start/rest-button 34 thecontrol 40 runs in a kind of emergency mode and releases at once at least one warning signal. Preferably an acoustic and an optical warning signal are released or generated by thecontrol 40 to direct the operator's attention to the hot steam inside the drum 4. - The acoustic warning signal is released e.g. by means of a buzzer or a
speaker 35 of the operatingpanel 30 to the operator. The warning signal can be e.g. a beep or a spoken warning like “attention—hot steam”. - The optical warning signal is released by means of an optical display preferably arranged in the front of the home dryer 1.
- The optical display can be e.g. a lamp, particularly a
red lamp 36 or a LED-display or the LCD-display 31. The optical warning signal can thus be only a red warning light or in case of the LCD-display 31 red blinking words like “attention—hot steam”. - Additionally to the release of the warning signals the
control 40 stops after registering an interruption of a run of a program for treating textiles with steam the further supply of hot steam of the steam unit to the drum 4. Thecontrol 40 especially stops the operation of the pump 21 of the steam unit and the operation of the heating of theheat generator 22 of the steam unit. - The supply of steam to the drum 4 can thereby be stopped by closing the
conduit 24 by amagnetic valve 25 which is attached to theconduit 24 and controlled by thecontrol 40. - A further possibility to stop the supply of steam to the drum 4 containing the textiles can be the reversion of the flux of the steam through the steam unit. By a reversion of the flux of the steam through the steam unit thus the steam generated by the
steam generator 22 do not flow through theconduit 24 and theinjector 23 in direction to the drum 4 but flows in the opposite direction. The pump 21 of the steam unit which normally pumps water out of awater tank 20 into thesteam generator 22 is thereby preferably operated in a reversed mode. In the reversed mode the pump 21 is operated in an opposite direction and pumps the steam already generated and still present in thesteam generator 22 into thewater tank 20. The pump 21 is thereby controlled by thecontrol 40. - Another action to protect an operator is to deplete the steam unit of the home dryer 1 of the steam, when an interruption of a run of a program for treating textiles with steam occurs. This can be achieved by a
magnetic valve 26 attached to the steam unit. E.g. themagnetic valve 26 is attached to a conduit connecting the pump 21 und thesteam generator 22. The opening and closing of themagnetic valve 26 is controlled by thecontrol 40. When an interruption of a run of a program for treating textiles with steam occurs, themagnetic valve 26 is opened in direction to aconduit 27 which is attached to themagnetic valve 26 and the steam is conducted by means of theconduit 27 in a part or in parts of the home dryer 1 to which the operator has as a rule no contact or no access. - When the
conduit 27 is connected to themagnetic valve 25 the steam unit can also be depleted of the steam by means of themagnetic valve 25 and theconduit 27. In this case themagnetic valve 26 is not necessary. - Another action taken by the
control 40 in case of an interruption of a run of a program for treating textiles is to conduct as fast as possible the hot steam contained in the drum 4 out of the drum 4. This can be done by a separate conduit connected to the drum 4 and equipped with a controllable valve. But preferably theconduit 7 for the supply air and/or theconduit 9 for the exhausted air are used for conducting the hot steam out of the drum 4. In case of the on hand embodiment theconduit 7 for the supply air is used because of thefan 14 inside theconduit 7. So thecontrol 40 can activate the motor 16 in such a way that the hot steam is conducted out of the drum 4 by means of thefan 14 which is operated in the reverse direction in comparison to the drying mode (see arrow inFIG. 2 ). - In case of an interruption of a run of a program for treating textiles with steam by switching one of the
buttons control 40 blocks thedoor 3 with a not explicitly shown closing device of themechanism 17. Thedoor 3 can thereby not be opened until there is no more danger for an injury for the operator. Preferably thedoor 3 is blocked by thecontrol 40 for a certain period of time, e.g. 1 minute, and/or until the temperature and/or the atmospheric moisture in the drum 4 has reached a certain value. The value of the temperature can be registered with aseparate temperature sensor 19 connected to thecontrol 40 or in a respectively way with a not shown temperature sensor of thesteam generator 22 whereby based on the temperature of thesteam generator 22 and a known cool down behaviour of the steam in the drum 4 thecontrol 40 computes the temperature in the drum 4. The value of the atmospheric moisture can be registered with aseparate sensor 28 connected to thecontrol 40 or with a already existing sensor of the home dryer 1. - The invention was afore described in connection with a home dryer of the condensation type. But the invention is not limited to home dryer of the condensation type. The invention is also applicably in home dryers using a wet exhausted air process as illustrated in
FIG. 3 . Components shown inFIG. 3 which are in type and function identically or comparably with components shown inFIG. 2 have the same reference numerals. - In case of the embodiment of
FIG. 3 heated air is conducted in the drum 4 by means of theconduit 7 for supply air, theheating element 8 and thefan 14 for drying wet textiles contained in the drum 4. The air charged with moisture is conducted from the drum 4 to the outside of the home dryer. - The home dryer of
FIG. 3 can like the home dryer ofFIG. 2 be operated with at least one program for treating textiles in the drum 4 with hot steam. For protection of an operator in case of an interruption of a program for treating textiles with steam the same actions can be taken as described above. Acoustic and optical warning signals can be released in the same way. The supply of steam to the drum 4 can be stopped by thecontrol 40. The steam unit can be depleted of steam. The steam contained in the drum 4 can be conducted out of the drum by means of theconduit 7 and thefan 14 whereby the fan can be operated in both turning direction. Also thedoor 3 can be blocked for a certain period of time and/or until the temperature in the drum 4 has reached a certain value. - As mentioned before the invention is also applicable to washing s machines comprising a steam unit and an operating mode for treating textiles with hot steam.
- As described above a lot of actions can be taken in case of an interruption of a run of a program for treating textiles with steam for the protection of an operator. Thereby it is not necessary to take all the described actions. It can be sufficient to take only one action or any adapted combination of the described actions that the operator is not hurt by hot steam.
