Automatic control method of air suction equipment and air suction equipment

Abstract

The invention relates to an automatic control method of air suction equipment and the air suction equipment. The control method comprises the following steps: A, arranging the air suction equipment at a plurality of different height grade positions above a stove in advance, respectively measuring the temperature values of the stove at the different height grade positions, and then analyzing the starting threshold value of each height grade position; B, during actual cooking of the stove, measuring the actual distance between the air suction equipment and the stove through distance measuring equipment on the air suction equipment to obtain the actual measurement height H, comparing the obtained actual measurement height H with height grades for judgment, determining which height grade the actual measurement height H most approaches, and obtaining the starting threshold value corresponding to the height grade; C, detecting the temperature of the stove in real time, and acquiring and obtaining a real-time temperature correlation value; and D, comparing the real-time temperature correlation value with the obtained starting threshold value, and controlling the air suction equipment to be started when the real-time temperature correlation value reaches the starting threshold value. Starting and stopping or power adjustment of the air suction equipment can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to an automatic control method for air suction equipment and the air suction equipment. Background technique [0002] When cooking is turned on, many people often forget to turn on the range hood. Harmful substances such as oil fume and PM2.5 will accumulate in large quantities during the cooking process, causing pollution to the indoor kitchen environment, which in turn affects the health of users. Forgetting to turn off the range hood will also cause Waste of power resources. For temperature measurement in a certain area, the industry usually chooses an infrared temperature sensor with single-point detection or multi-point detection. The sensor is installed at the bottom of the exhaust fan or OTR and is not affected by cooking utensils. It is a non-contact type Measurement. [0003] However, in the actual application process, due to the different kitchen ...

Problems solved by technology

[0003] However, in the actual application process, due to the different kitchen space and cabinet styles, the actual installation height of the range hood will change. Under different installation heights, the temperature change curve of the infrared temperature sensor during the cooking process is also inconsistent.

At present, the traditional method is basically to control the range hood according to the temperature change value or temperature change rate set by the factory, and the selected threshold is fixed, so that when the range hood is installed at a high The effect of quickly starting or shutting down the fan, when the installation height of the range hood is low, it is easy to cause accidental startup or shutdown
