Abstract

The invention provides a noise reduction structure and a range hood. The noise reduction structure comprises a front plate, a sound absorption part and a rear plate, wherein the sound absorption partis arranged opposite to the front plate; the rear plate is connected with the front plate to form a containing cavity, the containing cavity is suitable for containing the sound absorption part, and at least one of the front plate and the rear plate is provided with a plurality of connecting parts in a protruding mode in the direction back on to the other one of the front plate and the rear plate.Through the built-in sound absorption part, noise from the direct-facing direction of the front plate or the rear plate is blocked, the noise reduction structure can be arranged at the position of anair inlet of the range hood, airflow impact sound and other noise transmitted from the air inlet are effectively weakened, in addition, the protruding connecting parts ensure that a gap exists between the noise reduction structure and the air inlet, lampblack can smoothly enter the air inlet, the noise reduction structure is easy to install and low in cost, the defects that in the prior art, a noise reduction structure of a range hood is complex in design and high in noise reduction cost are overcome while noise is reduced, and the life quality of a user is improved.

Description

technical field [0001] The invention relates to the technical field of household kitchen utensils, in particular to a noise reduction structure and a range hood. Background technique [0002] In the era of rapid economic development, people's requirements for the living environment are getting higher and higher. Therefore, the range hood that removes kitchen fumes has become one of the must-have appliances in every home kitchen. It solves the problem of kitchen fumes very well, but the noise generated inside the range hood due to factors such as fan movement or airflow impact during the cooking process , but has been troublesome. [0003] In the existing technology, there are many ways to reduce the noise of range hoods. In addition to the optimization and improvement of sound-absorbing materials, etc., it is mainly to optimize the fan structure and its motion form to reduce the noise generated when the fan rotates. The method has the disadvantages of complex noise reducti...
