Description
Technical field
The present invention relates to a kind of impeller assembly and its air-conditionings, belong to air-conditioning technical field.
Background technology
Air conditioner is as a kind of household electrical appliance generally used, traditional air conditioner, air duct and channel system and bottom case
As a whole, fixation is assembled at first as basic part, if need to unpick and wash, need each part of the professional to air-conditioning
Cleaning is split out after being split, it is highly inconvenient.
And during air-conditioning is used for a long time, the dust and other impurities that air duct and water channel are entered from air inlet make entire wind
Road, channel system are seriously polluted, if cleaning will bring harm during operation of air conditioner as pollution sources to environment not in time,
Have great importance to the health of user.
In order to solve the above-mentioned technical problem, Chinese patent literature CN20279231051U discloses a kind of wall convenient for unpicking and washing
Hanging air-conditioner indoor machine casing comprising the shell and rack mutually fastened, rack is split type, when cleaning, is first unloaded shell
Under, the fixed screw between upper spider and lower bearing bracket is dismantled, then lower bearing bracket removes, then unloads the fixation of impeller and impeller motor axis
Screw continues the reinforcing ring up and down for removing a side stand component, you can easily unload impeller.That is, needing in the prior art
First lower bearing bracket to be removed, and impeller is fixedly mounted at impeller motor on lower bearing bracket, therefore, impeller and impeller motor
It is removed with lower bearing bracket, then dismantles the screw between impeller and impeller motor again, is i.e. the dismounting of impeller and motor is complicated.This
Outside, impeller one end in the prior art is fixedly connected with motor using screw, and the other end is spindle rotationally arranged on bottom case,
That is be vacantly arranged between impeller and motor, although impeller is adopted with impeller motor axis and is screwed when fixed, connection
Reliably, still, when disassembled, operating personnel are needed to live impeller with hand rest always, otherwise, impeller can be fallen in dismounting.
In order to solve the technical problem of above-mentioned dismounting complexity, Chinese patent CN2823621Y discloses a kind of household electrical appliance
Blower fan apparatus comprising a kind of coupling arrangement, the coupling arrangement include the leaf at the other end center for being embedded in the fan
Motor support axle sleeve that is nested and being fixedly mounted on driving motor main shaft is taken turns, one or more is provided in the impeller nesting
Mounting groove, the motor support axle sleeve are provided with one or more installation cards, when need to remove fan cleaned when, it is only necessary to
Fan is moved into a certain distance to fan end axis direction, so that it may easily to take out fan.The i.e. above-mentioned prior art middle period
Wheel is first removed with lower bearing bracket with impeller motor, then mobile fan, and fan and motor are separately removed fan.Because this is existing
Impeller one end in technology is connect with motor by coupling arrangement, and the other end is spindle rotationally arranged on bottom case, that is to say, that
Impeller support sleeve is still hanging link together with motor support axle sleeve.Impeller is moved along axis makes impeller support shaft
Set detached with motor support axle sleeve after, impeller support sleeve does not have supporting point so that impeller it is crooked with fall, may cause
Impeller blade is impaired.Moreover, when impeller support sleeve and motor support axle sleeve are assembled, the joint face tune of two support sleeves is relied only on
Whole centering, it tends to be difficult to ensure that impeller axle is conllinear with motor shaft, to accelerate the abrasion of impeller axle and motor shaft.
