Description
The application be submit on April 18th, 2008, denomination of invention divides an application for the application for a patent for invention that is 200810092965.2 of " for motor, fan and the filter for installation of vacuum cleaner ", application number.
Technical field
The vacuum cleaner that the present invention relates to a kind of motor for vacuum cleaner, fan and filter for installation and comprise this motor, fan and filter for installation.
Background technology
Well-known vacuum cleaner is mainly used in collecting dust and dirt, although can collect the dry wet modification (wet-and-dry variant) of liquid, is also known.Conventionally, vacuum cleaner is for home environment, although vacuum cleaner also can be used in other environment such as building site.Conventionally, they are electronic, therefore comprise motor and be connected to the fan of motor output shaft, for the entrance of foul atmosphere, for the outlet of pure air and for dust, dirt and dust storage chamber that also may liquid.Can provide electrical power for motor by main line power supply, in this case, vacuum cleaner can be by detachable and interchangeable battery pack or the power cable providing by one or more inbuilt rechargeable batteries by further comprising, in this case, this vacuum cleaner is by further comprising some devices such as plug, for vacuum cleaner is connected to and recharges unit.When providing electrical power from one of these sources for vacuum cleaner, Motor Drive fan, to suck foul atmosphere by dirty air inlet along air flow path, then arrives pure air outlet via dust storage chamber.
Also a certain device is arranged on to certain the some place along gas channel, described device is for separating of going out the dust and dirt carried secretly in foul atmosphere (and also possible liquid) and these dust and dirt being deposited in dust storage chamber.This separator can comprise one or more filters and/or cyclone separation equipment.Traditionally, as fruit separation device comprises filter, motor, fan and filter have the device as schematically shown in Fig. 1.As can be seen from Figure 1 the foul atmosphere that, has entered vacuum cleaner via dirty air inlet flow to region Q by filter 30 from region P.This separates the dust and dirt of carrying secretly in foul atmosphere (and also possible liquid), and therefore filtering material is retained in the P of region.If filter 30 itself is arranged in collecting chamber as conventionally, the filtering material being retained in the P of region just accumulates in there.Then pure air flow to the 3rd region R from the region Q of filter 30 opposite sides by the grid 42 being formed on wall 40, and its middle filtrator 30 is arranged on wall 40.Although additional filter can be set, grid 42 does not have filter effect conventionally.Its main purpose is to prevent that user from approaching the fan 20 on the motor output shaft 12 that is arranged on motor 10 on the contrary, and when providing electric power by electric terminal 14,16 for motor 10, motor 10 is by vacuum cleaner air amount.As shown in Figure 1, fan 20 is impellers, and it is axially to its blade face air amount the tangential air of discharging, and then air flow to the pure air outlet of vacuum cleaner from here.The example of hand-holdable vacuum cleaner with conventional motor, fan and the filter of Fig. 1 is also illustrated in the open No.EP1523916A of European patent with the applicant's name.
Therefore the conventional apparatus of above-mentioned motor, fan and filter has formed three separated region P, Q and R, and second area wherein, region Q is actually " " space extremely.In other words, region P can be used for for described filtering material provides dust storage chamber, and region R holds motor 10 and fan 20, and region Q only takes up room and unreal incumbent what object.On the one hand, filter 30 should have large as far as possible surface area to improve its filter effect, and this tends to increase the size of region Q.This surface of conventionally avoiding exactly crossing in the position of grid 42 fan 20 why arranges the reason of flat filtration device.Although this can save region Q completely, owing to forming bottleneck in air flow path, this little filter also can seriously reduce the efficiency of vacuum cleaner.In addition,, in order further to improve the efficiency of filter 30, often filter is arranged to cylindrical or frusto-conical shape.This shape impels the foul atmosphere in the P of region to walk around filter 30 turns before by filter 30, and this has and under the centrifugal action in cyclone separator, deviates from the effect that filter 30 is outwards thrown out dust and dirt particle.On the other hand, yet, if be necessary for filter 30, provide larger surface area or such shape, so in order to save space and to reduce region Q size, the possibility that fan 20 and possible same parts or whole motor 10 are inserted in the Q of region is also not expected, because this will hinder the pure air outlet that flows out to vacuum cleaner from the tangential air of discharging of fan 20, but make the inner surface of the air impact filter 30 of being discharged by fan, thereby relative with the pure air flowing into by filter 30, and again seriously reduce the efficiency of filter operation.
Therefore the use of the conventional apparatus of motor, fan and the filter shown in Fig. 1 in its space is poor efficiency, but but significantly can not solve this way to solve the problem of itself.In compact or hand-held vacuum cleaner, it is undesirable especially that the space of this poor efficiency is used, and in such vacuum cleaner, effective use in space is considerable, the space of any waste all must increase the overall weight of described vacuum cleaner, and can not bring any benefit suitable with it.
Summary of the invention
Therefore the object of this invention is to provide a kind of motor for vacuum cleaner, fan and filter for installation, this device can utilize space better than the conventional apparatus shown in Fig. 1.Another object of the present invention is to provide a kind of motor, fan and filter for installation being particularly suitable in compact or hand-held vacuum cleaner.Another object of the present invention is to provide a kind of vacuum cleaner that comprises this motor, fan and filter for installation.
Therefore, in first aspect, the invention provides a kind of vacuum cleaner, this dust catcher comprises: motor; Fan, this fan is connected to the output shaft of motor and has axial air entrance; And filter; Wherein, fan is configured such that to its axial entrance is in the face of motor; And motor is accommodated in filter.This device makes it possible to along the direction contrary with conventional apparatus, described motor is arranged in filter, thereby makes before meeting with fan, to be inhaled into motor from the pure air of filter.Therefore by the output shaft from motor on motor output shaft, stretch out, still fan can be arranged on to filter outside, make the air of being discharged by fan can not be subject to the obstruction of filter, and still can easily flow to the pure air outlet of vacuum cleaner.In addition, owing to being inhaled into motor before the pure air experience fan from filter, so the useful side effect of the air cooling motor that is used to inherent filtration device is also provided, and unlike the conventional apparatus of Fig. 1, if motor has been carried out by the air of being discharged by fan coolingly in the conventional apparatus of Fig. 1, 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 will be incorporated in air-flow and reduce the whole efficiency of vacuum cleaner.In contrast, motor of the present invention, fan and filter for installation do not need to make the air of being discharged by fan to change circuit, and because motor holding is in filter, thus realized effective use in space, and be therefore particularly suitable in compact or hand-held vacuum cleaner.
Motor of the present invention, fan and filter for installation also have obvious advantage: in view of the fan in the conventional apparatus of Fig. 1 is the impeller of tangentially discharging air, and fan in motor of the present invention, fan and filter for installation can be impeller or screw, the latter from by fan by an air shaft side shaft relative to the surface sucking to discharging air.This is because in conventional apparatus, the back side of fan is subject to the obstruction of motor, therefore the air flowing out from fan must tangentially be drawn, and in motor of the present invention, fan and filter for installation, the back side of fan is not blocked, make from fan air can either as in impeller, tangential discharge again can axial discharge as in screw.This provides great multifunctionality for comprising the master-plan of the air-flow in the vacuum cleaner of this motor, fan and filter for installation, 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 being arranged between motor and filter.Therefore, if be for example dismountable in order to clean or replace its filter, housing can prevent that user from approaching motor and fan, but air still can arrive fan from filter by housing.Motor shell can be air-locked alternatively, and in this case, device also can comprise the grid being arranged between motor and fan, and motor output shaft is through this grid.Therefore, air-locked housing prevents that user from approaching the electric parts of motor completely, but air still can arrive fan from filter by grid.For the user, this possibility is more safer than breathable motor shell, but also has corresponding shortcoming, can not to motor, carry out cooling by the air from filter.
Preferably, the output shaft of motor extends from filter interior, and one end of output shaft is installed on bearing, and this bearing is arranged on the fan side contrary with motor.Like this, the axial entrance that leads to fan can not be subject to stopping of motor or bearing, this has improved the aerodynamic efficiency of the air-flow that enters fan, and the motor output shaft extending supports by bearing, when fan rotates, this can prevent that the motor output shaft extending is because any potential imbalance in fan is vibrated.
In second aspect, it is a kind of according to the vacuum cleaner that comprises motor, fan and filter for installation of first aspect present invention that the present invention also provides.Described vacuum cleaner comprises: motor; Fan, described fan is connected to the output shaft of described motor, and described fan has axial entrance; And filter; Wherein said fan is configured such that its axial entrance is in the face of described motor; And described motor holding is in described filter; It is characterized in that: described vacuum cleaner is hand-held vacuum cleaner, it comprise main part, handle and with the dust storage chamber of the longitudinal axis vertical orientation of described main part, described dust storage chamber has tangential inlet pipeline, makes the foul atmosphere that enters described dust storage chamber when described dust catcher operation around described filter turn.Preferably, this vacuum cleaner is hand-held vacuum cleaner, the saving space that this hand-held vacuum cleaner can utilize this motor, fan and filter for installation to provide substantially.
