An automatic cleaning range hood

Abstract

The invention discloses an automatic cleaning smoke exhaust ventilator. The automatic cleaning smoke exhaust ventilator comprises a smoke exhaust ventilator body; the smoke exhaust ventilator body mainly comprises a transmission shaft, a transmission bevel gear, residual gears, a bidirectional screw rod and cleaning plates; a driving motor is arranged at the upper end of the smoke exhaust ventilator body; the lower end of the driving motor is rotatably connected with the transmission shaft; the lower end of the transmission shaft is fixedly connected with each of the transmission bevel gear and an exhaust fan; the two ends of the transmission bevel gear are respectively engaged with a driven bevel gear; each driven bevel gear is fixedly connected with a driven shaft; each driven shaft is fixedly connected with a residual gear; the lower end of each residual gear is partially engaged with a large gear; the large gears are fixedly connected with the bidirectional screw rod; the cleaning plates are arranged at the lower end of the bidirectional screw rod; the lower ends of the cleaning plates are pressed against an air inlet plate. According to the smoke exhaust ventilator, the cleaning plates are driven to move left and right through discontinuous positive and negative rotation of the bidirectional screw rod, so that the exhaust fan is driven to rotate to exhaust while the cleaning plates are driven to move left and right to clean by one power source; a motor is fully utilized; electric resources is saved; the cleanness degree of the smoke exhaust ventilator is improved.

Description

technical field [0001] The invention relates to a household appliance, in particular to an automatic cleaning range hood. Background technique [0002] According to the research report of WHO, among the 4.3 million people who died from kitchen air pollution in the world in 2012, stroke accounted for 34%, chronic obstructive pulmonary disease and ischemic heart disease accounted for 22% and 26% respectively. Accounted for about 6% of lung cancer. The dietary structure of Chinese is different from that of Westerners, so the variety, style and layout of kitchen utensils in the kitchen are very different from those of Western countries. China is a country that pays attention to food. In food processing, frying, frying, cooking, and deep-frying account for a large proportion. Therefore, there is a lot of oil fume in Chinese kitchens, which easily makes the kitchen environment greasy and difficult to clean. Therefore, smoking oil fume The machine has become an essential machine ...

Problems solved by technology

[0003] At present, the common range hoods in the market have complex and changeable structures, but there are basically no range hoods with automatic cleaning function. The range hood cleans the kitchen air by absorbing oil and gas, but the oil stains accumulated inside the range hood are relatively difficult to deal with. The longer the oil stains adhere to the range hood, the more difficult it is to clean. The oil stains on the range hood should be able to absorb the oil fume and discharge the oil stains at the same time.
