Abstract
Disclosed is a ceiling blower for exhausting and exchanging air for buildings, which changes the traditional method that the motor of the present ceiling blower is arranged in a blowing cover. The apparatus moves the motor to the outside of the blowing cover so as to greatly improve the working environment of the motor and avoid the motor body directly being invaded by a great amount of damp and dirty gas exhausted by an impeller and effectively extend the service life of the blower.
Description
The utility model relates to a kind of air bells conditioner of building.Mainly be installed in the roof of all kinds of buildings, as the usefulness of indoor exhaust ventilation.
The existing roof ventilator that is installed on the roof as FW4～75 air draft type roof ventilators, is to be sent out several parts such as orchid to constitute by blast cap, airduct, fan housing, motor, impeller, fan housing.This roof ventilator is arranged because motor shaft and impeller shaft are same axis, and all is arranged among blast cap and the fan housing, thereby ventilator when work, through a large amount of humidity of impeller discharge, filthy air-flow, directly pounce on the motor body, thereby seriously influenced the working life of whole ventilator.
In view of the problem of above-mentioned existence, the axis that the purpose of this utility model provides a kind of motor shaft and impeller shaft is the novel external motor formula roof ventilator that the De ， And that is arranged in parallel can significantly improve its working life.
The task that the utility model proposed realizes that by following measure it moves to the motor of blower fan outside fan housing, the axis of motor shaft and impeller shaft is is arranged in parallel, and motor shaft connects to transmit its power by belt with impeller shaft.
The utility model is owing to move to motor outside fan housing, thereby improved the working environment of motor widely, avoided directly attacking the motor body by a large amount of humidities, filthy gas that impeller is discharged, thereby improved effectively the working life of blower fan.
Concrete structure of the present utility model is by providing in the accompanying drawing.
Fig. 1 is the structural representation of external motor formula roof ventilator.
External motor formula roof ventilator is made of parts such as blast cap (1), fan housing (2), motor (3), impeller (4), fan housing falan seats (5), motor (3) is arranged at outside the fan housing (2), the axis of motor shaft and the axis of impeller shaft are and are arranged in parallel, and motor shaft connects by belt (6) with impeller shaft and transmits its power.During blower fan work, humidity, filthy gas through fan housing falan seat (5), fan housing (2), are arranged to atmosphere from the opening of blast cap (1) under impeller (4) effect within doors.
Claims (1)
1, a kind of outer cover motor type roof ventilator that contains blast cap (1), fan housing (2), impeller (4), fan housing falan seat (5), the motor (3) that it is characterized in that this blower fan is arranged at outside the fan housing (2), the axis of motor shaft and impeller shaft is and is arranged in parallel, and motor shaft connects by belt (6) with impeller shaft and transmits its power.
