Novel oil screen

Abstract

The invention discloses a novel oil screen. An outer oil screen is positioned outside an inner oil screen; the inner oil screen and the outer oil screen are provided with first ventilation holes and second ventilation holes respectively; a side wall of each first ventilation hole is provided with a first turned edge which forms a set included angle with the first ventilation hole; the inner periphery of each second ventilation hole is provided with a second turned edge which faces the inner oil screen and has a closed ring shape; the first ventilation holes and the first turned edges corresponding to the first ventilation holes completely cover just above the second ventilation holes and the second turned edges corresponding to the second ventilation holes; and the lower end of each first turned edge is just positioned between two adjacent second turned edges corresponding to the outer oil screen. Through the novel oil screen, air flow has a smooth flow line during flowing, and the loss of air quantity is small; the air flow hardly forms eddy current when passing through the inner oil screen and the outer oil screen, so the noise is low; the oil smoke is mainly processed by a surface filtration method, so the gas can contact larger areas of the inner oil screen and the outer oil screen during movement to achieve a good oil smoke filtering effect; and since both the inner oil screen and the outer oil screen are at a certain angle with the horizontal plane, oil drops can smoothly flow into an oil collection cup.

Description

Technical field [0001] The invention relates to an oil net for a range hood, in particular to a novel oil net. Background technique [0002] Existing range hood oil nets generally have a one-layer structure, and basically have the following shortcomings: [0003] 1) The oil network has poor oil guiding performance and will leak oil; [0004] 2) After the range hood is installed with the oil net, the noise will increase significantly; [0005] 3) The oil net is not effective in filtering oil fume; [0006] 4) After the range hood is installed with the oil net, the air volume loss is great. Summary of the invention [0007] In order to make up for the above shortcomings, the present invention provides a new type of oil net, which has strong oil conduction performance, good filtering effect on oil smoke and low noise. [0008] The technical solution adopted by the present invention in order to solve its technical problems is: a new type of oil net, including an inner oil net and an outer o...
