Range hood

Abstract

The invention relates to the technical field of kitchen utensils, in particular to a range hood. The range hood comprises a box body assembly and a silencing assembly arranged in the box body assembly; the silencing assembly is inclined relative to the corner position inside the box body assembly at an angle; and the angle between the silencing assembly and the vertically-arranged side wall of thebox body assembly is in the range of 20-60 degrees. With adoption of the range hood, the silencing assembly is arranged in the corner position of the box body assembly and is inclined relative to thecorner position of the box body assembly at the angle, so that silencing and noise reduction can be performed on cooking fume inside the range hood, the flow guiding effect on the cooking fume can also be realized, and the cooking fume suction effect can be improved. Preferably, the angle between the silencing assembly and the vertically-arranged side wall of the box body assembly is in the rangeof 20-60 degrees, so that flow guidance and sound absorption are better facilitated. Besides, the range hood is simple in structure, reasonable in design and high in practicability, the machining technology is simple and convenient, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a range hood. Background technique [0002] The range hood includes a box body and a fan assembly arranged in the box body, and the fan unit is driven by a motor to suck out the oil fumes in the range hood. Fans, motors and airflow are important sources of noise. Among them, aerodynamic noise includes eddy currents entering the cabinet, radiation noise to the outlet of the volute, and reverberation noise inside the range hood. [0003] Generally, aerodynamic methods are used to optimize the centrifugal fan and volute, or a low-noise motor is used, or sound-insulating or sound-absorbing materials are used. Although the above-mentioned various passive noise reduction methods can also reduce noise, they have a single function, and often reduce the exhaust air volume of the range hood while reducing noise, and also affect the vibration noise of the outer wall of the range h...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a range hood with simple structure, reasonable design and the ability to effectively achieve the effect of noise reduction and noise reduction while improving the intake efficiency, so as to solve the existing noise reduction methods to reduce the exhaust of the range hood. Noise reduction is achieved at the expense of smoke volume and the problem of single noise reduction functionality
