Description

The motor, fan and the filter for installation that are used for vacuum cleaner

Technical field

The present invention relates to a kind of motor, fan and the filter for installation of vacuum cleaner and vacuum cleaner that comprises this motor, fan and filter for installation of being used for.

Background technology

Well-known vacuum cleaner is mainly used in the collection dust and dirt, also is known although can collect the wet modification (wet-and-dry variant) of doing of liquid.Usually, vacuum cleaner is used for home environment, although vacuum cleaner also can be used in other environment such as the building site.Usually, they are electronic, therefore comprise motor and the fan that is connected to motor output shaft, be used for foul atmosphere inlet, be used for the outlet of pure air and be used for dust, dirt and dust storage chamber that also maybe liquid.Can be that motor provides electrical power through the main line power supply; In this case; Vacuum cleaner will further comprise can be through detachable and interchangeable battery pack or the power cable that provides through one or more inbuilt rechargeable batteries; In this case, this vacuum cleaner will further comprise some devices such as plug, be used for vacuum cleaner is connected to recharging the unit.When for vacuum cleaner electrical power being provided from one of these sources, the motor driven fan arrives the pure air outlet via dust storage chamber then to suck foul atmosphere through dirty air inlet along air flow path.

Also a certain device is arranged on certain the some place along gas channel, said device is used for isolating dust and dirt (and also possible liquid) that foul atmosphere carries secretly and these dust and dirt is deposited in the dust storage chamber.This separator can comprise one or more filters and/or cyclone separation equipment.Traditionally, comprise filter like fruit separation device, then motor, fan and filter have the device as schematically showing among Fig. 1.As can be seen from Figure 1, the foul atmosphere that has got into vacuum cleaner via dirty air inlet flow to regional Q through filter 30 from regional P.This separates the dust and dirt of being carried secretly in the foul atmosphere (and also possible liquid), and therefore filtering material is retained among the regional P.If as usually, filter 30 itself is arranged in the collecting chamber, the filtering material that then is retained among the regional P just accumulates in the there.Pure air flow to the 3rd region R from the regional Q of filter 30 opposite sides through the grid 42 that is formed on the wall 40 then, and its middle filtrator 30 is installed on the wall 40.Though the additional filtering device can be set, grid 42 does not have filter effect usually.Its main purpose is to prevent the user near the fan 20 on the motor output shaft 12 that is installed in motor 10 on the contrary, and when for motor 10 electric power being provided through

electric terminal

14,16, motor 10 sucks air through vacuum cleaner.As shown in Figure 1, fan 20 is impellers, and it axially sucks air and tangential discharge air to its blade face, and air flow to the pure air outlet of vacuum cleaner from here then.The instance of hand-holdable vacuum cleaner with conventional motor, fan and filter of Fig. 1 also is illustrated in open No.EP 1 523 916 A of European patent with the applicant's name.

The conventional apparatus of therefore above-mentioned motor, fan and filter has formed three separated region P, Q and R, and second area wherein, regional Q is actually " " space extremely.In other words, regional P can be used for for described filtering material provides dust storage chamber, and region R is held motor 10 and fan 20, and regional Q only takes up room and unreal incumbent what purpose.On the one hand, filter 30 should have big as far as possible surface area to improve its filter effect, and this tends to increase the size of regional Q.This surface of avoiding crossing in the position of grid 42 fan 20 exactly why usually is provided with the reason of flat filtration device.Although this can save regional Q fully, owing in air flow path, form bottleneck, this little filter also can seriously reduce the efficient of vacuum cleaner.In addition, in order further to improve the efficient of filter 30, often be arranged to cylindrical filter or frusto-conical shape.This shape impels foul atmosphere among the regional P through walking around filter 30 turns before the filter 30, and this has and deviates from the effect that filter 30 is outwards thrown out the dust and dirt particle under the centrifugal action in cyclone separator.On the other hand; Yet; If be necessary for filter 30 bigger surface area or such shape are provided,, the possibility that fan 20 and possible same parts or whole motor 10 are inserted among the regional Q also can not be expected so in order to save the space and to reduce regional Q size; Because this will hinder the air of discharging from fan 20 tangentials to flow out to the pure air outlet of vacuum cleaner; But make the inner surface of the air impact filter 30 of discharging by fan, thus relative with the pure air that flows into through filter 30, and seriously reduce the efficient of filter operation once more.

Therefore the conventional apparatus of motor, fan and the filter shown in Fig. 1 is being a poor efficiency aspect the use in its space, but but significantly can not solve this way to solve the problem that itself exists.In compact or hand-held vacuum cleaner; Use in the space of this poor efficiency is undesirable especially; And in such vacuum cleaner; Effective use in space is considerable, and the space of any waste all must increase the overall weight of said vacuum cleaner, and can not bring any benefit suitable with it.

Summary of the invention

Therefore the purpose of this invention is to provide a kind of motor, fan and filter for installation that is used for vacuum cleaner, this device can utilize the space better than the conventional apparatus shown in Fig. 1.Another object of the present invention provides a kind of motor, fan and filter for installation that is particularly suitable in compact or the hand-held vacuum cleaner.Another purpose of the present invention provides a kind of vacuum cleaner that comprises this motor, fan and filter for installation.

Therefore, in first aspect, the present invention provides a kind of motor, fan and filter for installation that is used for vacuum cleaner, and this device comprises: motor; Fan, this fan are connected to the output shaft of motor and have the axial air inlet; And filter; Wherein, fan is configured such that its axial entrance is in the face of motor; And motor is accommodated in the filter.This device makes it possible to the edge direction opposite with conventional apparatus said motor is arranged in the filter, thereby makes the pure air from filter before meeting with fan, be inhaled into motor.Therefore stretch out through output shaft on motor output shaft, still can fan be arranged on the filter outside, make the air of discharging can not receive the obstruction of filter, and still can easily flow to the pure air outlet of vacuum cleaner by fan from motor.In addition; Owing to before the pure air from filter meets with fan, be inhaled into motor; So the useful side effect of the air cooling motor that is used to the inherent filtration device also is provided; And unlike the conventional apparatus of Fig. 1, if in the conventional apparatus of Fig. 1, through the air of being discharged by fan motor is cooled off, air will have to change route to cross motor from the outflow of fan so.This will need air-flow to change direction, thereby aerodynamic drag is incorporated in the air-flow and has reduced the whole efficiency of vacuum cleaner.In contrast; Motor of the present invention, fan and filter for installation need not make the air of being discharged by fan change circuit; And because motor holding is in filter, thus realized effective use in space, and therefore be particularly suitable in compact or the hand-held vacuum cleaner.

Motor of the present invention, fan and filter for installation also have tangible advantage: in view of the fan in the conventional apparatus of Fig. 1 is the impeller that air is discharged in the tangential; And the fan in motor of the present invention, fan and filter for installation can be impeller or screw, the latter from through fan with air shaft to a surperficial relative side shaft that sucks to the discharge air.This is because in conventional apparatus; The back side of fan receives the obstruction of motor; Therefore the air that flows out from fan must be drawn the tangential; And in motor of the present invention, fan and filter for installation, the back side of fan is not blocked, and making can either again can be like axial discharge in the screw as discharging in tangential in the impeller from the air of fan.This is that the master-plan that comprises the air-flow in the vacuum cleaner of this motor, fan and filter for installation provides great multifunctionality, thereby can freely guide the air of being discharged by fan.

Motor of the present invention, fan and filter for installation also can comprise the ventilative housing that is arranged between motor and the filter.Therefore, if be dismountable in order to clean or replace its filter for example, then housing can prevent the user near motor and fan, but air still can arrive fan from filter through housing.Motor shell can be air-locked alternatively, and in this case, device also can comprise the grid that is arranged between motor and the fan, and motor output shaft passes this grid.Therefore, air-locked housing prevents the electric parts of user near motor fully, but air still can arrive fan from filter through grid.For the user, this possibility is more safer than breathable motor shell, but also has corresponding shortcoming, promptly can not motor be cooled off through the air from filter.

Preferably, the output shaft of motor extends from filter interior, and an end of output shaft is installed on the bearing, and this bearing is arranged on the fan side opposite with motor.Like this; The axial entrance that leads to fan can not receive stopping of motor or bearing; This has improved the aerodynamic efficiency that gets into the air-flow of fan; And the motor output shaft that prolongs supports through bearing, and when fan rotated, this motor output shaft that can prevent to prolong was owing to any potential imbalance in the fan is vibrated.

In second aspect, the present invention also provides a kind of vacuum cleaner that comprises motor, fan and filter for installation according to first aspect present invention.Preferably, this vacuum cleaner is a hand-held vacuum cleaner, the saving space that this hand-held vacuum cleaner can be utilized this motor, fan and filter for installation substantially and provided.
