The motor of household ventilation fan of the present invention is carried out heat dissipating method is: when machine operation, air-flow is inhaled into the inside of spiral case and all surface of full motor from the intake grill of spiral case; Then, the gas between each surface of blade and motor is in the zone that moves under the effect of the centrifugal force of blade between blade and the spiral case, and air-flow leaves described ventilation fan from the exhaust outlet of spiral case subsequently.
Compared with prior art, the invention has the beneficial effects as follows: by the motor integral body of ventilation fan being arranged at fully the inside of spiral case, under driving, the centrifugal force that wind wheel produces forces motor surface integral air motion, thereby motor has been realized whole wind cooling temperature lowering, effectively solved the problem low owing to the bad utilization efficiency that causes of motor surface radiating, that the life-span is short.And in the prior art, the structure that motor section is placed in the spiral case causes the whole or most surfaces of motor not have the motion of air-flow, so that the motor under current affects produces the high heat of high temperature, reduce motor speed and make the Efficiency Decreasing of ventilation fan, accelerate the aging of motor enamel-covered wire, shorten electrical machinery life.The air-flow that the structural design of household ventilation fan of the present invention produces when utilizing motor self work accelerates the motor surface radiating, temperature reduces, so that the hot resistance of motor winding reduces, improved operating current, rotating speed and the efficient of motor have been improved, thereby improve air quantity and the blast of ventilation fan, realize that the ventilation fan whole work efficiency improves, and effectively reduced machine operation and generated heat on the impact in motor utilization efficiency, life-span.The present invention has improved overall efficiency, the Security of product and the working life of product effectively by the raising of the motor ventilation radiating effect of ventilation fan, reduces simultaneously energy consumption.The invention enables maintenance and the maintenance of ventilation fan to become convenient and easy, such as when motor damages, only need pull down ventilation front plate, unload wind wheel, unload under electric machine support damaging motor again, i.e. replaceable new motor, and do not change again after will the ventilation fan complete machine not taking off from furred ceiling.
