Abstract
The utility model relates to a blower of cleaner without volute and guide pulley, which is improved on the base of present blower of cleaner without volute and guide pulley, air through the filter cloth goes into the dynamo of vacuum cleaner first, then goes into the centrifugal impeller through the hole in bearing cap, and then to meet the requirement of aspiration in the way of direct expulsion. The utility model reduces the drag force for air stream caused by volute and guide pulley, decreases the current drain, and has the advantages of simple structure and low cost.
Description
The utility model is applicable to vacuum cleaner without the vacuum cleaner blower fan of spiral case and guide wheel, and it is by motor of dust collector, and receded disk impeller and outer cover etc. are formed.
The vacuum cleaner blower fan that present vacuum cleaner is adopted, as the People's Education Publishing House, in April, 1988 Liao Quanzhu that front page is published 297 pages in home appliance repair handbook in the vacuum cleaner blower fan introduced, it is by receded disk impeller, spiral case, guide wheel, outer cover, and motor of dust collector etc. are formed.Deficiency is to use spiral case and guide wheel, and the air by receded disk impeller is discharged at first passes through spiral case and guide wheel, enters motor by the hole on the bearing cap again, the cooling winding, and then the through hole from motor housing is discharged.Will overcome the resistance of spiral case and this section of guide wheel like this, consume certain electric energy, spiral case and guide wheel increase the increase of vacuum cleaner volume, cost on the other hand, design the vacuum cleaner blower fan without spiral case and guide wheel in order to overcome above-mentioned deficiency.
Above-mentioned purpose reaches by following measure, it is that receded disk impeller is fixed on the axle head of motor of dust collector, and the air sucking mouth conversely towards the bearing cap of motor of dust collector, bearing cap becomes the passage of drawing the motor internal air having the hole of leading to motor internal facing to place, receded disk impeller air sucking mouth.The motor of dust collector the other end is that shell just had the air hole with exterior originally.There is outer cover at the back side of receded disk impeller, and it is fixed by bolts on the motor housing by gasket ring.The motor air outside enters motor internal by the air of filter cloth from the through hole on the motor housing earlier when motor rotates like this, is directly being dished out by impeller by the receded disk impeller suction through the hole on the bearing cap, then by discharging for the exhaust port of vacuum cleaner again.Realized reducing power consumption and the purpose that reduces manufacturing expenses without spiral case and guide wheel.
Now further specify as follows in conjunction with the accompanying drawings:
Accompanying drawing is the vacuum cleaner blower fan structure sketch without spiral case and guide wheel.
On the axle (7) of motor in the accompanying drawing (1) receded disk impeller (3) is housed, its air sucking mouth is towards the bearing cap (2) of motor (1) and bearing cap (2) has the hole facing to the place, air sucking mouth of receded disk impeller (3).Close to each other and the not phase grazing of the face that bearing cap (2) is relative with receded disk impeller (3), and make air in the motor (1) can lead to the air sucking mouth of receded disk impeller (3).There is outer cover (4) at the back side of receded disk impeller (3), and it is fixed on the shell of motor (1) by bolt (6) by gasket ring (5).Linked up inside and outside vent because motor of dust collector (1) shell just has originally, air-flow will enter the inside of motor (1) from motor (1) outside when motor rotates, and be sucked then by receded disk impeller (3) air sucking mouth and be dished out by centrifugal force.Such method has reached not spiral case and guide wheel is realized cutting down the consumption of energy and the purpose of cost.
Comparing it with the blower of cleaner that spiral case and guide wheel are arranged that uses now without the blower of cleaner of spiral case and guide wheel, to have energy consumption low, the advantage that cost is low.
Claims (3)
1, by motor of dust collector, receded disk impeller, the vacuum cleaner blower fan that outer cover is formed without spiral case and guide wheel, it is characterized in that: the air sucking mouth of receded disk impeller (3) is fastened on the axle (7) of motor (1) towards the bearing cap (2) of motor (1), case (4) is fixed on the motor (1) by bolt (6) by gasket ring (5), is covering the back side of receded disk impeller (3).
2, according to the vacuum cleaner blower fan without spiral case and guide wheel of claim 1, it is characterized in that: the bearing cap (2) of motor (1) has perforate to lead to motor internal facing to the place, air sucking mouth of receded disk impeller (3).
3, according to the vacuum cleaner blower fan without spiral case and guide wheel of claim 1, it is characterized in that: the close to each other and not grazing of bearing cap (2) and receded disk impeller (3) facing surfaces.
