The kitchen ventilator is arranged above a kitchen stove, and can rapidly pump away waste burnt by the stove and oil smoke harmful to human bodies generated in the cooking process, discharge the waste and the oil smoke out of a room, reduce pollution and purify air. The first range hood was developed from china in 1984, and the range hood has changed greatly in appearance style, including chinese style, european style, side draft type and L type, in more than 30 years in china, and shows diversified trend. However, the control mode is not changed all the time, and a mechanical switch or an electronic switch is usually adopted for control, so that manual opening and closing are required. Before cooking in a kitchen starts, the range hood needs to be remembered to be manually opened, the wind speed needs to be manually adjusted in the cooking process, and after the cooking is finished, the range hood needs to be manually closed after waiting for a period of time. Such an operation mode often causes a problem that the range hood is not opened until half of cooking is finished or the range hood is not opened, or the wind speed of the range hood is not adjusted in the cooking process, so that the kitchen is filled with oil smoke, the kitchen environment is greasy, and toxic substances contained in the oil smoke cause harm to human health.
For this reason, the current solutions are: 1) the gas stove controller is connected with the thermocouple flame detection module, when the thermocouple flame detection module detects flame combustion, the wireless transmission module on the gas stove sends a detection value to the wireless receiving module of the range hood, the range hood controller controls the fan module to start, and when the thermocouple flame detection module detects that no flame is combusted on the gas stove, the range hood controller controls the fan module to stop working. 2) Culinary art sound control lampblack absorber starts or closes, through the sound in the analysis kitchen, detects the various environment sound in kitchen, and then judges whether this sound is the sound that the culinary art process sent, sets up starting or closing of range hood and adjusts the rotational speed of fan to reach the intelligent control to range hood.
The above scheme has at least the following problems: 1) the linkage system of the gas stove and the range hood needs the gas stove and the range hood to be used together, and the gas stoves and the range hoods of different brands cannot be matched.
