Abstract
The utility model discloses a wind guide ring. The wind guide ring comprises a body, wherein the body is in a volute shape, and the inner wall of the body is uneven. The wind guide ring with the structure solves the problem that noise is too high when a draught fan works. Experimental results show that the noise can be lowered by 20%-25% after the wind guide ring is used under the condition of the same power. Therefore, the wind guide ring is remarkable in effect.
Description
Technical field
The utility model discloses a kind of air-ducting ring, be used for the fume treating devices such as kitchen ventilator, integrated kitchen range.
Background technique
Cigarette cigarette machine, integrated kitchen range are domestic very universal fume treating devices, and it has improved the cooking environments in kitchen greatly.Present cigarette cigarette machine, the core of integrated kitchen range are blower fans, reach the purpose that absorbs oil smoke by blower fan, blower fan mainly is comprised of wind wheel and air-ducting ring, and present ubiquitous problem is, during blower fan work, noise is larger, cooking environments is affected, sometimes the invasion and attack of this noise of people's endurable.
The model utility content
The purpose of this utility model is to provide a kind of air-ducting ring, and this air-ducting ring can reduce the noise that the fume treating device inner blower sends, and improves the culinary cuisine environment.
In order to achieve the above object, the technical solution of the utility model is:
A kind of air-ducting ring comprises body, and this body is scroll casing shape, and described inner body wall is roughness.
As the further setting of such scheme, described inner body wall is wavy; Or be provided with row's square groove in described inner body wall; Or be provided with some recess holes on described inner body wall.
After adopting said structure, the large problem of noise when the utility model has solved blower fan work, be mainly roughness because of inner body wall, a plurality of planes of refraction have been increased, noise is absorbed through Multi reflection in propagation process weakens, through test in the situation that equal-wattage, after using the utility model, noise can reduce original 20%-25% left and right, successful.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model embodiment 2 expansion schematic diagram;
Fig. 3 is the utility model embodiment 3 expansion schematic diagram.
Embodiment
Embodiment 3, and as Fig. 3, a kind of air-ducting ring comprises body 1, and this body 1 is scroll casing shape, and described body 1 inwall is roughness.Specifically body 1 inwall is provided with some recess holes 3.
The large problem of noise when the utility model has solved blower fan work, be mainly roughness because of inner body wall, a plurality of planes of refraction have been increased, noise is absorbed through Multi reflection in propagation process to be weakened, through testing in the situation that equal-wattage, after using the utility model, noise can reduce original 20%-25% left and right, successful.
Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
