Description

technical field [0001] The invention relates to the field of home appliances, in particular to a range hood for automatic cleaning of oil filters. Background technique [0002] Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed in the kitchen and has the advantages of health and energy saving. The range hood is generally set above the stove, which can quickly suck away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it outdoors to reduce pollution and purify the air. It also has the function of anti-virus and explosion-proof safety guarantee. [0003] After the traditional range hood has been used for a period of time, a lot of oil stains stick to the surface of the metal filter. Although there is a waste oil collection box under the metal mesh, part of the waste oil will flow into the waste water along the slope of the metal filter. ...

Problems solved by technology

[0003] After the traditional range hood has been used for a period of time, a lot of oil stains stick to the surface of the metal filter. Although there is a waste oil collection box under the metal mesh, part of the waste oil will flow into the waste water along the slope of the metal filter. In the oil collection box, there is still a considerable part of oil stains sticking to the surface of the metal filter. These oil stains block the unsealed filter holes, resulting in a decrease in the passage of the smoke and a decrease in the efficiency of the suction, which in turn leads to the inability of the oil fume to discharge. Timely discharge, threatening the health of personnel
