RANGE HOOD SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/023389
Kind Code:
A1
Abstract:
Disclosed is a range hood system, comprising a housing (1), an air blower and a range hood control circuit board, wherein an air inlet (3), an air outlet (4) and an air duct (2) are arranged on the housing (1), the air blower and the range hood control circuit board are mounted in the housing (1), the air blower comprises a blower motor (6) and a fan (7), the fan (7) is driven by the blower motor (6), the blower motor (6) drives the fan (7) to rotate, so that air enters the air duct (2) from the air inlet (3) and then is output from the air outlet (4), the blower motor (6) comprises a motor controller (62) and a motor unit (61), the motor unit (61) comprises a stator component (612), a rotor component (613) and a housing component (611), the stator component (612) is mounted on the housing component (611), the stator component (612) is magnetically coupled with the rotor component (613), the motor controller (62) comprises a motor control circuit board (621), a microprocessor and an inverter circuit are arranged on the motor control circuit board (621), the microprocessor controls the inverter circuit, the inverter circuit controls electric current of each phase coil winding of the stator component (612), and the blower motor (6) is a permanent magnet brushless direct current motor with constant air quantity control, and can automatically regulate operating parameters to output constant air quantity according to different external static pressures.
