Problems solved by technology

[0004] In the prior art, the condensing plate is mainly to expand the smoking effect, but in terms of noise, it is a disadvantage of increasing the noise. Because the condensing plate affects the path of the air flow, the fluency of the air flow is reduced, and the vortex generated by the incoming air is increased. Possibly, the air intake noise becomes louder, which reduces the user's experience of using the range hood

Abstract

The invention discloses a range hood, comprising: a machine body and a baffle plate, the body has an air flow driving module and a smoke guide hood, and the smoke guide hood is provided with a smoke inlet connected to the air flow drive module; The baffle is opposite to the smoke inlet, and there is a smoke inlet passage between the baffle and the smoke hood, wherein a noise reduction structure is provided between the baffle and the smoke hood. The range hood according to the embodiment of the present invention has a good noise reduction effect.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a range hood. Background technique [0002] In the product development process of range hoods, the air volume and air pressure are getting bigger and bigger, and the noise is developing in the direction of silence. In terms of quietness, except for measures to optimize the air duct, methods such as active noise reduction and passive noise reduction are gradually applied to range hoods. The air duct optimization is an excellent method in terms of noise reduction. The main reason is that the air duct optimization has little effect on the performance of the fan, but generally has a very ideal effect on noise reduction. [0003] In the near-suction range fume, most of the volutes are directly connected with deflectors or other rectification devices, which can reduce the cyclone generated by the smoke. At the same time, in the structure of the existing technical scheme, there is a c...
