Also include the air draft case, in the air draft case, be provided with air exhaust channel, said exhaust port communicates with air exhaust channel.
Also include retainer ring, be provided with fastening flange at the middle part of said drive motor, this fastening flange is vertical with said output shaft, and the inboard of retainer ring is connected with fastening flange, and the outer ring is connected with said worm gear.
Two said intake grills are located at respectively on the axle side of said spiral case, and two axle sides are vertical with said output shaft.
Advantage or principle in the face of the aforementioned techniques scheme describes down:
1, because drive motor is located at the middle part of spiral case, can be through two axle sides difference air intakes of spiral case, air output is bigger, and the resistance during exhausting is littler, and it is more steady to work, and effectively improves the smoke discharging effect of range hood;
2, fixing frame comprises central sleeve and at least three fixed arms that circumferentially are uniformly distributed with, can be with stable being installed on the spiral case of drive motor;
3, in central sleeve, be provided with cushion collar, the vibration in the time of can effectively reducing the drive motor operation reduces noise;
4, plane, fixed arm place is parallel with respect to said output shaft, makes fixed arm little on axial projection plane, avoids air intake is impacted;
5, drive motor adopts external rotor electric machine, and more steady during its operation, operational noise is little;
6, the fastening flange of drive motor is connected with worm gear through retainer ring, and simple in structure, retainer ring also plays compartmentation to two axle sides;
7, the axle side of spiral case is vertical with output shaft, reduces the shared space of spiral case.
