Abstract

The invention discloses a system for controlling a range hood by utilizing a cooker sensor. The system is characterized by comprising an information processing circuit, a heating sensing circuit, a pan temperature sensing circuit, a heating control circuit and a range hood control circuit, wherein the heating sensing circuit, the pan temperature sensing circuit, the heating control circuit and the range hood control circuit are connected with the information processing circuit, and the information processing circuit is used for controlling the heating control circuit and the range hood control circuit to operate according to feedback information of the heating sensing circuit, the pan temperature sensing circuit and the heating control circuit. According to the system, the pan temperature sensing circuit is arranged, so that a sensor for oil smoke does not need to be additionally arranged on the range hood, the judgment is accurate, the reliability is high, and the service life is long; the current cooking condition can be sensed, and the subsequent cooking condition can be automatically controlled, so that the variation trend of the oil smoke is indirectly sensed, intelligent control modes of a cooker and the range hood can be conveniently corrected in time, the condition that the air quantity changes before the oil smoke quantity changes is realized, and the intelligent control effect of the range hood is increased.

Description

technical field [0001] The invention relates to a linkage control technology of kitchen appliances, in particular to a system for controlling a range hood by using a cooker sensor. Background technique [0002] At present, there are generally two types of automatic control methods for range hoods in the industry. One is to match different cooker firepower to different range hood modes, and directly control the speed of the range hood motor by detecting the cooker firepower. The other is to control the speed of the range hood motor by directly sensing the concentration of the oil fume by setting a fume sensing device on the hood, the stove or other positions in the kitchen. The former type of control method is not one-to-one corresponding to the size of the firepower and the size of the oil fume, so the control of the range hood is very rough and the accuracy is low. The latter type of control method, because the oil fume sensing device (including chemical sensor, optical s...
