Abstract

The present invention relates to a motor axial ventilation structure for blower fan, including fan housing, motor casing, with motor air inlet, sound-eliminating heat-insulating layer, perforated plate, guide blade, motor, hub and blade wheel, which is characterized by that between motor casing and perforated plate an annular channel is formed, the front end of motor casing is fixedly connected with ventilation ring, a half-open blade is fixedly-connected on the hum off blade wheel, the air vent of ventilation ring is opposite to air-inlet end of half-open blade, the internal diameter of rear end of blade wheel hub is greater than external diameter of front end of motor casing to form ring air vent blowing to surface of motor casing. As compared with existent technology is possesses the following advantages: adoption of motor axial ventilation structure can greatly increase motor ventilation flow grantity, effectively solve the problems of dust-proofing, damp-proofing and cooling of general motor, good effect and prolonging service life of motor.

Description

The motor shaft of blower fan is to aeration structure
The motor shaft that the present invention relates to a kind of motor ventilation structure of blower fan, particularly a kind of blower fan is to aeration structure.
In order to keep the proper functioning of blower fan, must take certain dust and moisture measure to motor, motor dust and moisture measure in the blower fan at present has following several substantially: a kind of is that its shortcoming is that the using scope of blower fan is restricted by the service condition of control blower fan and the normal use that temperature guarantees motor.Second kind is to select motor according to the blower fan service condition, and the motor performance grade has determined the structure of blower fan, thereby is subjected to the restriction of motor dust and moisture.The third is that motor is exposed in the physical environment, and it is damp to lower the temperature, loose by natural heat dissipation, but subjects to wind and weather, dust infringement, influences its working life.
The motor shaft that the purpose of this invention is to provide a kind of blower fan is to aeration structure, motor dust and moisture, good cooling effect.
The objective of the invention is to be achieved through the following technical solutions: it comprises motor casing, noise elimination thermal-protective coating, perforated plate, stator, motor, wheel hub, impeller of Fan casing, translator intake grill etc., it is characterized in that: between motor casing and perforated plate, constitute annular channel, the affixed venting ring of the front end of motor casing, affixed half-open blade on the hub of impeller, the air intake of the half-open relatively blade of the ventilated port of venting ring, the back end inside diameter of impeller hub constitutes the ring-type ventilated port to the blowing of motor casing surface greater than the front end external diameter of motor casing.Working principle: by the motor intake grill inspiration natural wind of motor casing, and through constituting annular channel and venting ring between motor casing and the perforated plate, discharge from ventilated port vertically, between the half-open blade of motor and impeller, set up a low-temperature airflow district, under high-temperature work environment, effectively accelerate the discharge of motor heat, half-open blade strengthens the motor ventilation flow, air-flow blows out from the ring-type ventilated port, axially discharges along motor case, reaches the effect of motor cooling.Simultaneously because axially blowing makes common electric machine reach the effect of dust and moisture.
The present invention compares with prior art has following advantage: owing to adopt motor shaft to strengthen the motor ventilation flow to aeration structure, efficiently solve the dust and moisture and the cooling of common electric machine, using effect is good.Prolong the working life of motor.
Provide embodiments of the invention below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment:
See Fig. 1-3, motor casing 9 is fixed in the Fan casing 11 by stator 8, elastic insert 7 and link 10, and motor casing 9 is provided with motor intake grill 15, motor casing 9 inboard assembling noise elimination thermal-protective material 12 and perforated plates 13.Front end at motor casing 9 passes through supporting plate 4, venting ring 1 and the affixed motor 14 of connecting bolt, motor shaft passes venting ring 1, the affixed impeller 5 of its front end, affixed half-open blade 3 on the hub 2 of impeller, the air intake of the half-open relatively blade 3 of the ventilated port of venting ring 1, the back end inside diameter of impeller hub 6 constitutes the ring-type ventilated port to the blowing of motor casing surface greater than the front end external diameter of motor casing 9.
