Low-noise range hood

Abstract

The invention discloses a low-noise range hood. The low-noise range hood solves the problems that in the prior art, the working efficiency of the range hood is reduced caused by the fact that oily fume scale adheres to the inner wall of an oily fume separation pipe, oily fume mixtures coagulated on the bottom surface of an oily fume suction cover drip on a kitchen stove to bring trouble to a user,and the noise is high and does harm to body health of an operator are solved. The low-noise range hood comprises an oily fume suction cover body, an oily fume separation box body, a waste gas discharging pipe, a flange, a control box, a microprocessor, an acousto-optical alarm, a smoke concentration sensor, a flange oil collecting tank, an oily fume extracting pipe, an oily fume separation pipe,a negative-pressure fan, an oily fume separation fan, an electric push rod, an oil push knife, a separation pipe oil collecting tank, a waste oil collecting box, an oil guide tank and a closed cavity.The low-noise range hood can clear oily fume scale on the inner wall of the oily fume separation pipe, can effectively collect a small amount of oily fume mixtures coagulated on the bottom surface ofthe oily fume suction cover, can prevent part of the oily fume mixtures from dripping on the kitchen stove, can reduce the working strength of the user, can effectively reduce noise and is favorablefor body health of an operator.

Description

technical field [0001] The invention relates to a range hood with low noise. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. It is installed above or on the side of the kitchen stove. It can quickly suck away the waste burned by the stove and the harmful oil fume generated during the cooking process, and discharge it outdoors to reduce pollution. Existing range hoods generally have a waste oil collection tank in the oil fume separation box, and an oil collection cup is connected to the bottom of the waste oil collection tank. It flows into the waste oil collection tank, and finally enters the oil collection cup to be disposed of, but the inner wall of the oil fume separation box is easy to adhere to a thick layer of oil fume after years of use, which will increase the oil fume in the oil fume separation box to pass through the oil fume Separate the resistivity of the cabinet, which will reduce the working efficiency...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to provide a low-noise range hood to solve the problem that the oil smoke dirt on the inner wall of the oil fume separation tube in the prior art is easy to adhere to reduce the working efficiency of the range hood, and the bottom surface of the range hood will condense during use. A small amount of oily fume mixture, and this part of the oily fume mixture will drip onto the kitchen stove along the bottom of the range hood, which will cause trouble for the user to clean the kitchen stove, and the loud noise is not good for the health of the operator
