Abstract

The invention discloses a control method of a range hood, which comprises the following steps: 1) the user starts cooking; 2) the range hood is turned on, and the fan of the range hood starts to run; 3) a temperature sensor starts to detect and obtain the current range hood The size reference value of the cooking utensil on the cooker below, the current temperature of the central point of the cooking utensil, the temperature change value of the central point of the cooking utensil, and the duration; 4) the data unit reads the pre-stored and currently detected temperature According to the user's usage habit data corresponding to the data, the predicted oil fume amount Qp is obtained according to the user's usage habit data, and the fan gear of the range hood is pre-adjusted according to Qp; 5) The actual amount of oil fume detected by the oil fume sensor is Qp', When Qp' is greater than Qp, increase the speed of the fan; when Qp' is smaller than Qp, reduce the speed of the fan; when Qp' is equal to Qp, keep the fan at the current gear.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a control method for a cooking fume machine. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] During the working process of the traditional range hood, the motor speed of the fan is fixed, that is, the gear of the fan is fixed...
