Abstract

The invention discloses a device for detecting the greasy dirt degree of smoke exhaust. The device comprises a capacitance detecting module and a control module, wherein a first input end of the capacitance detecting module is connected with a metal screen; a second input end of the capacitance detecting module is connected with a metal oil guide tank; the capacitance detecting module is used for detecting the capacitance value between the metal screen and the metal oil guide tank; the control module is connected with the output end of the capacitance detecting module, and is used for judging the greasy dirt degree according to the capacitance value. Through adoption of the device, the greasy dirt degree of a smoke exhaust can be accurately acquired, and a user is prompted when the amount of greasy dirt is relatively large, so that the user can clean off the greasy dirt in time; the detecting device is simple, reliable, small in size and low in cost, and can be easily integrated into the smoke exhaust. The invention further discloses the smoke exhaust and a method for detecting the greasy dirt degree of the smoke exhaust.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a device for detecting the degree of oil pollution of a range hood, a range hood and a method for detecting the degree of oil pollution of the range hood. Background technique [0002] At present, because the range hood cannot accurately judge the degree of oil pollution of the metal filter screen, the user cannot clean the metal filter screen and the metal oil guide groove in time, thereby affecting the use effect of the whole machine and the sanitation of the kitchen. [0003] In the related technology, an LED lamp containing ultraviolet light is used to irradiate the contamination on the metal surface, and at the same time, the intensity of UV fluorescence is measured through the photodiode in the probe of the measuring instrument. The stronger the UV fluorescence, the more serious the pollution, and vice versa. The cleanliness of the metal surface can ...
