Novel range hood oil filtering net

Abstract

The invention discloses a novel range hood oil filtering net which is arranged at a fume sucking hole of a range hood or at any position from the fume sucking hole to a range hood volute air inlet. The oil filtering net comprises an outer frame, wherein an air guide channel is formed in an edge of the outer frame; the outer frame is internally provided with a plurality of hollow metal tubes which are communicated with the air guide channel; a plurality of vent holes are formed in another edge of the outer frame; the other ends of the hollow metal tubes are connected with the vent holes. As a jungle-type arrangement structure is adopted for the metal tubes, hot oily fume can be well condensed on the outer surfaces of the metal tubes and subsequently flows into an oil cup below the range hood along the walls of the metal tubes, so that the capacity of oily fume condensation is greatly improved, the air resistance is alleviated, and the noise is reduced.

Description

[technical field] [0001] The invention relates to a novel oil filter net for a range hood. [Background technique] [0002] In our country's family kitchen, because people have the habit of stir-frying, a lot of oily smoke will be generated. Yet, although the oil filter screen that the air inlet position of existing range hood is used has various structures, still has following shortcoming, and its one mesh is too big and can't have the effect of real filtering oil dirt; Small ones are often greasy and difficult to clean (especially in northern areas where animal oil is used), and the wind resistance is large; third, some oil filters may produce obvious howling noises. [Content of the invention] [0003] The present invention overcomes the deficiencies of the above-mentioned technologies, and provides a new type of oil filter screen for range hoods. The metal tubes adopt a jungle-like arrangement structure, which better condenses the hot oil and gas on the outer surface of...
