Abstract
The utility model relates to a range hood air outlet seat with a noise-reducing function, which can reduce a noise during the working of a range hood. The technical scheme disclosed by the utility model is as follows: the range hood air outlet seat with the noise-reducing function comprises an air outlet seat body, and is characterized in that a barrel-shaped noise-reducing device is connected onto the air outlet seat body; and the noise-reducing device comprises a barrel-shaped surrounding plate, a noise-reducing pore plate coaxially arranged in the surrounding plate, and a noise-reducing material filled between the surrounding plate and the noise-reducing pore plate. The air outlet seat disclosed by the utility model is suitable for various range hoods.
Description
Technical field
The utility model relates to a kind of lampblack absorber air outlet seat, and particularly a kind of lampblack absorber air outlet seat with silencing function mainly is applicable in the various lampblack absorbers.
Background technology
Nowadays range hood becomes one of people kitchen imperative equipment, because therefore the most cooking method of the big oily quick-fried of custom of compatriots adopts the lampblack absorber of centrifugal fan big with its relative suction, noise ratio is lower and be subjected to the favor in market; Noise is generally from two aspects, the one, the noise that produces during wheel rotation, the 2nd, the turbulence noise that air-flow moves and sends in spiral case, how further to reduce noise, improve the culinary art comfortableness, be the subject matter that present each lampblack absorber producer needs to be resolved hurrily, existing denoising structure is based on the design that how to reduce the source of sound that has produced more.
Summary of the invention
The technical problems to be solved in the utility model is: the problem at above-mentioned existence provides a kind of lampblack absorber air outlet seat with silencing function, the noise when working to reduce lampblack absorber.
The technical scheme that the utility model adopts is: a kind of lampblack absorber air outlet seat with silencing function, comprise the spiral case and the air outlet seat body that are linked in sequence, it is characterized in that: between the air outlet of spiral case and air outlet seat body, connect a silencing means or connect a silencing means at the outlet air end of air outlet seat body, described silencing means comprises tubular coaming plate, the coaxial arrangement noise reduction orifice plate in this coaming plate, and is filled in the quieter material between coaming plate and the noise reduction orifice plate.
Evenly have one group of noise reduction hole on the described noise reduction orifice plate.
The diameter in described noise reduction hole is less than or equal to 3.5mm.
The thickness of described quieter material is 5mm-100mm.
Described quieter material adopts acoustical cotton, foamed plastics, aluminum fiber cotton or centrifugally glass-wool.
The beneficial effects of the utility model are: the utility model connects a silencing means at the air outlet seat body, utilizes the noise reduction orifice plate noise reduction of this silencing means, quieter material absorption portion noise, thereby the noise when having reduced lampblack absorber work; After tested, adopt this patent structure can effectively reduce noise 1.5dB-2.5dB.

The specific embodiment
As shown in Figure 1, present embodiment comprises air outlet seat body 1, and the hollow cylindrical silencing means that is connected with this air outlet seat body, and the air channel of described air outlet seat body 1 is communicated with formation air-out passage with the cavity of silencing means; Described silencing means comprises cylindric coaming plate 2, the coaxial arrangement cylindrical shape noise reduction orifice plate 3 in this coaming plate, and is filled in the quieter material 4 between coaming plate 2 and the noise reduction orifice plate 3; Wherein evenly have the noise reduction hole 5 that one group of diameter is less than or equal to 3.5mm on the noise reduction orifice plate 3, quieter material 4 adopts acoustical cotton, foamed plastics, aluminum fiber cotton or centrifugally glass-wool, and its thickness is 5-100mm.
As Fig. 2-shown in Figure 4, in actual the use, air outlet seat body 1 is installed on the air outlet place of spiral case 6, namely spiral case 6 directly is connected with the air outlet seat body 1 of lampblack absorber air outlet seat, and flue gas is discharged behind spiral case 6, air outlet seat body 1 and silencing means successively; As shown in Figure 5, also the silencing means of lampblack absorber air outlet seat can be connected in the air outlet place of spiral case 6, flue gas after spiral case 6, silencing means noise reduction, is discharged by air outlet seat body 1 successively.
After tested, after the employing present embodiment lampblack absorber air outlet seat, can effectively reduce noise 1.5dB-2.5dB.
