Noise can be seen everywhere in life. The noise in the home is mainly the noise in the kitchen, and the noise in the kitchen is mainly from the noise of cooking and range hoods. The current noise reduction method of range hoods is mainly to reduce the noise of the fan. , but as the main source of noise in the kitchen, the noise reduction effect has not been very satisfactory. The main function of the frame-type range hood is to prevent the spread of the range hood, concentrate the range hood in a certain area, and then suck it away. Compared with The noise and fume absorption effect of the traditional range hood is good, but not good enough, the noise problem is still difficult to solve, so it is necessary to improve the frame type range hood

The invention discloses a frame type range hood sound absorption box based on modified composite sound absorption cotton, and relates to the technical field of range hood noise reduction. The frame type range hood sound absorption box comprises a range hood shell, a frame and a smoke suction pipeline, wherein the range hood shell is mounted on a wall; the frame is mounted below the range hood shell; the smoke suction pipeline is mounted at the top of the range hood shell; and the modified sound absorption cotton is used as a sound absorption material so as to absorb noise of a kitchen range hood and noise generated by cooking. According to the frame type range hood sound absorption box based on the modified composite sound absorption cotton provided by the invention, the frame type range hood is improved under the condition that the performance of a range hood draught fan is not reduced, and the frame of the frame type range hood becomes a sound insulation device, so that the cooking sound or the noise of the range hood draught fan can be reduced to a large extent.
Description
technical field [0001] The invention relates to the technical field of noise reduction for range hoods, in particular to a frame-type sound-absorbing box for range hoods based on modified composite sound-absorbing cotton. Background technique [0002] Any sound that hinders people's normal rest, study and work, and any sound that interferes with the sound that people want to listen to is noise. In this sense, there are many sources of noise, such as the sound of cars on the street, the sound of talking in a quiet library, the sound of machinery on a construction site, and the loud sound of a neighbor's TV set are all noise. [0003] Noise can be seen everywhere in life. The noise in the home is mainly the noise in the kitchen, and the noise in the kitchen is mainly from the noise of cooking and range hoods. The current noise reduction method of range hoods is mainly to reduce the noise of the fan. , but as the main source of noise in the kitchen, the noise reduction effect ...
