Water curtain type filtering range hood

Abstract

The invention provides a water curtain type filtering range hood. The water curtain type filtering range hood comprises a fan housing, a fume collection hood, a fume guiding plate, an oil collection cup and a water curtain filtering mechanism. The water curtain filtering mechanism comprises a liquid storage tank, an air inlet net cover, a water outlet cavity and a circulating pump, wherein the liquid storage tank is connected with a liquid outlet pipeline, the water outlet cavity is formed in the edge of the air inlet net cover in a ring shape or in a surrounding mode, and a plurality of water outlets are formed in the lower end face of the water outlet cavity at intervals. The fume guiding plate is located below the air inlet net cover and can receive cleaning water or cleaning liquid flowing out of the water outlets and guide the cleaning water or the cleaning liquid to the oil collection cup. A return pipe is arranged between the oil collection cup and the liquid storage tank. Compared with the prior art, the water curtain type filtering range hood has the advantages that the water curtain filtering mechanism can wash and filter cooking fume entering the water curtain filtering mechanism, and meanwhile, the cleaning water or the cleaning liquid obtained after washing can automatically clean the back side of the fume guiding plate and the inner wall of the oil collection cup.

Description

technical field [0001] The invention relates to a range hood and belongs to the technical field of kitchen utensils. Background technique [0002] The range hood has entered thousands of households and has become a mass consumer product. Its main function is to remove the cooking fume and waste gas generated in the kitchen. At present, common range hoods are generally equipped with air ducts, blowers, oil filter screens and oil collection cups. There is an oil collecting cup, but it will be found that oil stains will accumulate in the air duct and on the fan, which is very laborious and time-consuming to deal with, and will increase the load of the fan and reduce the suction force; in addition, the oil filter and the oil collecting cup are removed After that, it is also very troublesome to deal with. [0003] For this reason, a lot of water-washing range hoods have been disclosed in the prior art, such as the Chinese utility model patent "Automatic Cleaning Range Hood" (au...

Problems solved by technology

However, due to the lack of consideration in the structural layout of the above-mentioned patents, the mixing density of water and air is not enough, resulting in poor washing effect of oil fumes, and the fan still needs to be cleaned irregularly. In the patent ZL200820145732.X, an additional protective cover is required, which will inevitably increase manufacturing. cost

[0006] Nowadays, in order to improve the effect of oil absorption, many range hoods generally add a smoke guide plate at the air inlet. The smoke guide plate is generally detachable for easy cleaning, but the smoke guide plate is generally large in size and made of metal, so the overall weight is relatively heavy. It is very laborious for housewives to disassemble and clean. How to combine washing with water and cleaning the smoke deflector and apply it to the range hood has always been the direction of efforts of researchers.
