INTELLIGENT RANGE HOOD AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/120260
Kind Code:
A1
Abstract:
An intelligent range hood and a control method therefor. The intelligent range hood comprises a housing, a fan (4), a smoke collecting hood (3), a smoke guide plate (6), a controller, and a sensor (8) used for detecting the concentration of oily smoke and/or water vapor inside or outside the housing. A signal output end of the sensor (8) is connected to a signal input end of the controller for electric signal communication, and the speed of a fan motor (5) and a vertical position of the smoke guide plate (6) are controlled by receiving an output signal of the sensor (8). The sensor (8) can sense the concentration of the oily smoke and/or the water vapor, the controller can automatically adjust the speed of the fan motor (5), so that the air volume of the fan (4) can match with the working condition of the range hood in real time. The distance between an air suction surface and a negative pressure zone and a smoke source is automatically adjusted by means of the lifting and lowering of the smoke guide plate (6), so as to adapt to the change of the working condition.
