A low-noise surround top-side range hood

Abstract

The invention relates to a range hood and in particular relates to a low-noise surrounding top side type range hood. The low-noise surrounding top side type range hood mainly comprises a shell, multiple oil fume separating plates and a plurality of fans, wherein the shell comprises a fume exhaust duct, two baffle plates, two back plates and two side walls; the two back plates are perpendicularly arranged at the outer sides of two opposite walls of the fume exhaust duct respectively, the baffle plate is arranged on the back plate, the baffle plate is provided with an inwards-concave arc from the opening direction of the fume exhaust duct to the rear part of the back plate, the two side walls are perpendicularly arranged at one end, away from the fume exhaust duct, of each back plate, and point to the opening side of the fume exhaust duct, the oil fume separating plates are arranged at the opening part of the fume exhaust duct at the inner side of the shell, the inner side of the back plate and the inner side of the side wall, fans are also arranged at the inner side of the fume exhaust duct and the inner side of the side wall, the shell is made of stainless steel, and a fireproof sound absorption coating is also coated on the shell. The low-noise surrounding top side type range hood has high oil fume suction efficiency, good air purification effect and low noise.

Description

technical field [0001] The invention relates to a range hood, in particular to a low-noise surround top-side range hood. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. It is installed on the upper part of the range hood. After the range hood is powered on, it drives the motor to make the wind wheel rotate at a high speed, forming a negative pressure area in a certain space above the range hood, sucking the indoor fume gas into the range hood, and the fume gas passes through it. The oil screen is filtered for the first oil fume separation, and then enters the inside of the hood air duct, and the oil fume gas is separated for the second time through the rotation of the impeller. The oil fume in the air cabinet is subjected to centrifugal force, and the oil mist condenses into oil droplets , collected into the oil cup through the oil circuit, and the purified flue gas is finally discharged outside along a fixed path, ...

AI Technical Summary

Problems solved by technology

However, the top-side range hood uses a fume collection hood, and the fume collection hood is mainly divided into three types: shallow hood, deep hood and cabinet hood, and the oil fume extraction rate of the shallow hood is only 40%. About 50%-60% of the oil fume extraction rate of the deep hood type is only 50%-60%, and the oil fume extraction rate of the cabinet hood type can only reach 95%.

Therefore, although the top-side range hood has the advantages of both the top-side air intake type range hood and the side-side air intake type range hood, the effect of the range hood is still average, and the user uses the top-side type range hood when cooking. There will still be part of the fume that cannot be sucked out; moreover, since the top-side range hood combines the features of the top-suction and side-suction range hoods, the side-suction range hood makes a lot of noise when in use The problem is also present in the patent

Therefore, this patent still has problems such as poor oil absorption rate and high noise, and cannot provide users with a comfortable cooking environment.
