Abstract

The invention discloses a noise reduction assembly and a range hood, the noise reduction assembly comprises a plurality of noise reduction elements, each noise reduction element comprises a shell and a connecting plate, a containing cavity is formed in the shell, and a micropore structure is arranged on one side of the shell; the connecting plate is arranged in the accommodating cavity, so that the accommodating cavity forms a winding channel, and the winding channel is communicated with the microporous structure; wherein the multiple noise reduction elements are arranged side by side, and the ends, provided with the micropore structures, of the multiple noise reduction elements are arranged in the same direction. The noise reduction assembly is simple in structure and has a better noise reduction effect.

Description

technical field [0001] The present application relates to the field of household appliances, in particular to a noise reduction component and a range hood. Background technique [0002] With the improvement of user needs, the oil suction range hood needs to reduce the noise during operation on the premise of meeting the core indicators such as air volume and static pressure. The aerodynamic noise is the main noise source of the oil-absorbing range hood. The aerodynamic noise generated by the fan system will be transmitted to the human ear through the air duct through the suction port of the oil-absorbing range hood. Therefore, adding a sound-absorbing structure to the air duct can effectively reduce the oil-absorbing range hood. the overall noise of the machine. [0003] In the existing scheme, a sound-absorbing resonant cavity is added on the inner wall of the air duct. In order to widen the sound-absorbing frequency band, the cavity is filled with porous sound-absorbing m...
