Abstract

The invention belongs to the technical field of kitchen ventilators, and provides a constant-air-volume output control method and a constant-air-volume output control system for a kitchen ventilator. The constant-air-volume output control method comprises the following steps of generating a corresponding air volume control command when receiving a user control command in a working process of the kitchen ventilator; detecting running diameters of a motor; judging whether the current exhaust air rate of the kitchen ventilator conforms to the air volume control command or not according to the running diameters and a constant-air-volume algorithm model; controlling the motor to run if the current exhaust air rate of the kitchen ventilator conforms to the air volume control command; generating a running parameter command of the motor if the current exhaust air rate of the kitchen ventilator does not conform to the air volume control command; controlling the motor in the kitchen ventilator to run according to the running parameter command of the motor; and detecting the running parameters of the motor. After the running parameters of the motor are adjusted circularly and repeatedly, the exhaust air rate of the kitchen ventilator is close to the air volume set by a user and tends to be constant, and a lampblack discharging effect is improved while sufficient exhaust air rate is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of range hood control, and in particular relates to a method and system for controlling constant air volume output of a range hood. Background technique [0002] The function of the range hood is to discharge the indoor oil fume to the outside or the flue. With the development of the city, the design of the flue of the commercial housing in the community is different from that of ordinary houses. If the range hood is controlled only by constant speed or constant current control, it will not be able to meet the sufficient air volume demand. For example, for the public flue, when the frequency of low-floor residents turning on the range hood is too high, the static pressure at the public flue position of the high-floor residents will increase. If the constant speed control method is adopted, the range hood will be damaged. Insufficient exhaust air volume leads to poor fume emission effect of the range hood. ...
