Down-draught type range hood

Abstract

The invention relates to a down-draught type range hood, which comprises a cabinet, a fan system arranged in the cabinet, a fume collection chamber vertically arranged on the tabletop of the cabinet and a filter unit obliquely arranged in the fume collection chamber, wherein the filter unit comprises at least two layers of filter plates which are provided with a plurality of air vents; the air vents on two adjacent layers of filter plates are distributed in a misaligned manner; a turnup is formed around each air vent; the fan system comprises a fan, a fume exhaust pipe and static fume adsorption equipment; the fume collection chamber is communicated with the inlet of the fan; the inlet of the fume exhaust pipe is connected with the outlet of the fan; and the outlet of the fume exhaust pipe is connected with the inlet of the static fume absorption equipment. Compared with the prior art, the range hood has better fume filtration effect and less air flow loss, can further purify exhausted fume and ensure the air exhausted into the outside meet the requirements of fume exhaust standards of food industry.

Description

technical field [0001] The invention belongs to the technical field of range hoods, in particular to a downdraft range hood. Background technique [0002] At present, the range hoods used to remove kitchen fumes are mostly near-suction, tower type, and deep type. In these range hoods, the fans are mostly installed above the cabinets, at the rear side or front of the gas cooker. Above, the entire range hood occupies a very large position in the upper space of the kitchen, and the space is oppressive, which is not conducive to the overall appearance of the kitchen. In recent years, some downdraft range hoods have appeared one after another, generally including a cabinet, a fan system installed in the cabinet, and a smoke collection room vertically arranged on the countertop of the cabinet and located at the rear of the stove. There is an air inlet, and the smoke collection chamber has a smoke collection chamber connected with the fan system. [0003] In the existing downdraf...

Problems solved by technology

However, since the pore diameter of the mesh is always much larger than the diameter of the oil droplets mixed in the oil fume, the ability to filter oil fume is limited, and the smaller the mesh, the easier it is for oil to accumulate around the mesh, causing the mesh to shrink or even be blocked. Seriously affect the air intake of the range hood, thus affecting the overall fume removal effect of the range hood

More importantly, these filters are difficult to clean after they are stuck with greasy dirt, which makes users not very troubled, so usually they can only be replaced after a
