Smoke quantity detection device and range hood

Abstract

The invention provides a smoke quantity detection device and a range hood, wherein the smoke quantity detection device comprises a sensor module and a control module, wherein the sensor module is used for detecting the smoke quantity data of the range hood; the control module is used for receiving the smoke quantity data coming from the sensor module and determining the smoke quantity according to the smoke quantity data; the control module is internally provided with a data calibration module; the data calibration module is used for determining that whether compensation calibration is carried out on the smoke quantity or according to the light quantity data received by the range hood; when the compensation calibration is determined to be carried out on the smoke quantity, smoke removal treatment is carried out by the range hood according to the smoke quantity after compensation calibration. After the smoke quantity detection device is used, the compensation calibration is carried out on the smoke quantity obtained by analysis of the control module according to the environmental factors such as oil dirt, so that light quantity proportion data deviation caused by the oil dirt can be compensated, the influence of the accuracy of smoke quantity detection to the detection performance of the smoke detection device is minimized, the accuracy of oil smoke detection is improved, and the smoke removal treatment of the range hood is conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a smoke detection device and a cigarette machine. Background technique [0002] The hoods in the related art generally adjust the suction by touching the buttons, and users often cannot effectively control the hoods when their hands are occupied. Moreover, when the buttons are touched, the foreign matter on the surface of the hood will flow into the food, affecting the hygiene of the food. In addition, oil, water, flour, etc. will also stick to the surface of the hood when the user touches the buttons, making the surface of the hood unhygienic. [0003] For this reason, it is also proposed in the related art that the amount of smoke generated during cooking can be detected, and the motor can be controlled based on the amount of smoke, so as to further control the suction force. Such as figure 1 As shown, a smoke detection device is installed in the hood, and the sm...

[0005] However, if Figure 4 As shown, as time changes, the light-emitting part and / or light-receiving part, and the transparent window outside the light-emitting part and / or light-receiving part will be covered with dirt such as grease, and the ratio of light intensity will also be reduced in a smoke-free state , where the light ratio is the ratio of the amount of light received when the hood is working to the amount of light received when the hood is not working, which greatly reduces the accuracy of smoke detection, making it impossible for the hood to remove smoke according to the actual situation and increasing energy consumption , which degrades the user experience
