Abstract

The invention relates to the field of kitchen appliances and aims at providing a low noise and large suction range hood. The low noise and large suction range hood comprises a main case provided with two inner side plates and a rear through hole located in the rear end, an air duct arranged in the main case, a smoke collecting hood arranged at the lower end of the main case, and a check valve arranged at the upper end of the main case. The low noise and large suction range hood further comprises two parallel micro perforated plates provided with silencing small hole sets, and two sound absorbing and noise lowering plates; the two opposite side ends of the air duct are each provided with an air inlet; the two micro perforated plates are opposite to the two air inlets one to one; and the two micro perforated plates correspond to the two inner side plates one to one and each press one sound absorbing and noise lowering plate to be connected with the inner side of the corresponding inner side plate. The low noise and large suction range hood has the large air volume and air pressure strong suction performance and is low in noise.

Description

Technical field [0001] The invention relates to the field of kitchen appliances, in particular to a range hood with low noise and large suction. Background technique [0002] The structure of a large-suction range hood can be understood from a large-suction range hood disclosed in the utility model of Chinese Patent Application No. CNCN201520806136.1; large range hoods often have the disadvantage of large noise when pursuing large air volume. Therefore, a design Both the strong suction performance of large air volume and pressure, and the low-noise large suction range hood with lower noise have become a problem to be solved urgently. Summary of the invention [0003] The purpose of the present invention is to overcome the problem of large noise in the current large range hood when pursuing large air volume, and to provide a low-noise large-suction range hood with high air volume and pressure and low noise . [0004] The specific technical scheme of the present invention is: [0005...
