Problems solved by technology

[0003] Therefore, the range hoods at the present stage have gradually changed from traditional side suction machines to light and thin hoods. However, due to the large thickness reduction of light and light hoods, the airflow flows quickly in the narrow hood space, resulting in low noise levels. The sharp deterioration has greatly affected the user experience

Abstract

The invention provides a noise reduction system and a range hood, relates to the technical field of kitchen electric equipment, and aims to optimize the structure of a thin range hood to a certain extent and improve the noise reduction and sound absorption capabilities of the range hood. The noise reduction system is used for the range hood and comprises a first sound absorption assembly, a second sound absorption assembly and a draught fan sound absorption assembly. A mounting part is formed on the fan sound absorption assembly, and a fan assembly of the range hood is arranged in the mounting part; the first sound absorption assembly is arranged at the rear end of the fan sound absorption assembly, the second sound absorption assembly is arranged opposite to the first sound absorption assembly and connected with a smoke guide plate of the range hood, and a sound absorption space is defined by the first sound absorption assembly, the second sound absorption assembly and the fan sound absorption assembly.

Description

Technical field [0001] The present invention relates to the technical field of kitchen electrical equipment, in particular, to a noise reduction system and a hood. Background technique [0002] The problem of suction hoods can solve the problem of flexible smoke generated during the kitchen, which has become one of the necessary appliances in the family. With the development of the suction hood, the demand for the oil hood has not only stayed in the ability of the cigarette, and the smoking hood has a smaller noise and smaller space occupancy. [0003] Therefore, the suction hoods in this stage have gradually changed from the traditional side suction machine to the lightweight hood, but because the thin hood is greatly reduced because the thickness is greatly reduced, the gas stream flows urgently in the narrow hoodroom space, leading to noise levels It is sharply deteriorated, which greatly affects the user's feelings. [0004] Therefore, there is an urgent need to provide a noi...
