Wind adjustment method for range hood

Abstract

The invention provides a wind adjustment method for a range hood, which comprises the following steps that (1) infrared signals are continuously transmitted by an infrared transmitter set at one end of an air inlet to an infrared receiver at the other end according to a certain frequency, and the collected infrared signals are transmitted by the infrared receiver to a controller; (2) an average of the infrared signals received in a plurality of sampling cycles is obtained by the controller; (3) the average of the infrared signals and a value of a preset gear section are compared by the controller to obtain the required gear value; (4) corresponding power gear signals are outputted by the controller to a motor, and timing and latching are performed; (5) Steps (2), (3) and (4) are repeated by the controller after the timed operation of the motor in a plurality of sampling cycles according to the real-time gear value. The wind adjustment method provided by the invention has the beneficial effects that the output power of the motor is controlled via the infrared signals, and the action is accurate and reliable; and the encoding and decoding rules of the infrared signals are simple, and the reliability is high.

Description

technical field [0001] The invention relates to the field of kitchen appliance control, in particular to a method for adjusting the wind force of a range hood. Background technique [0002] In the prior art, the wind power adjustment of the range hood is preset and fixed, and the user manually adjusts it based on subjective feeling. There are not many range hoods that can be automatically adjusted. The invention patent application with the application number 201010243014.8 discloses a The range hood motor power adjustment method automatically adjusts the motor output power by detecting the temperature signal. Although the motor output power can be automatically adjusted, the correlation between the temperature signal and the oil fume concentration is limited, and the wind power cannot be adjusted accurately according to the oil fume concentration. Contents of the invention [0003] Aiming at the defects in the prior art, the invention provides a method for adjusting the wi...
