Abstract

The utility model discloses a structural improvement of a range hood volute casing, which comprises a range hood volute casing body and a boosting noise reduction plate disposed inside a square air outlet of the range hood volute casing. The boosting noise reduction plate consists of a plate I and a plate II which are crossed, two ends of the plate I are respectively perpendicularly fixed on a pair of inner walls of the square air outlet of the range hood volute casing body, two ends of the plate II are respectively perpendicularly fixed on another pair of inner walls of the square air outlet of the range hood volute casing body, and the square air outlet of the range hood volute casing body are uniformly divided into four portions through the plate I and the plate II. Compared with the prior art, the structural improvement of a range hood volute casing increases air pressure by 2%, reduces noise by 1 decibel, leads the range hood volute casing to be in the best state, and can achieve better environment-friendly and energy-saving effect.

Description

A kind of architecture advances of cigarette machine spiral case
Technical field
The utility model relates to the range hood field, specifically is a kind of cigarette machine spiral case.
Background technology
At present, the mode of its use of cigarette machine spiral case of China's range hood product manufacturing industry production has multiple, and more general has: inwall does not have any rectification and supercharging noise-reducing design around the spiral case, by self power air-flow is rushed out fully, air turbulence, the blast instability, noise strengthens.
General cigarette machine spiral case passes through result of use analysis: though can satisfy the GB requirement substantially to above-mentioned cigarette machine spiral case, but whole air quantity, blast, noise are still undesirable, because the non-optimum data of each parameter, cause the wind speed running resistance big, air-flow has some setbacks, so produce bigger noise, air quantity, blast have been reduced, not environmental protection, not energy-conservation.
The utility model content
The purpose of this utility model provides a kind of blast that promotes, and effectively reduces the architecture advances of the cigarette machine spiral case of noise.
The technical solution of the utility model is such: a kind of architecture advances of cigarette machine spiral case, comprise cigarette machine spiral case body and the interior supercharging noise reducing plate of the square air outlet that is arranged at this cigarette machine spiral case body, this supercharging noise reducing plate is made of the plate one and the plate two that are the cross fork, the two ends difference vertical fixing of plate one is on the pair of inner wall of the square air outlet of cigarette machine spiral case body, the two ends of plate two respectively vertical fixing in another of the square air outlet of cigarette machine spiral case body to inwall on, by plate one and plate two the square air outlet of cigarette machine spiral case body evenly is separated into four.
Above-mentioned supercharging noise reducing plate is the cross steel plate.
By adopting the aforementioned techniques scheme, air-flow is evenly divided into 4 in the utility model through the spiral case air outlet time, when no matter which part air-flow is through air outlet after the rectification of criss-cross supercharging noise reducing plate blast uniform and stable, because of being divided into fritter, area reduces to some extent again, blast increases, the flow velocity of wind strengthens, and after the rectification of supercharging noise reducing plate, forces air-flow to concentrate in order, make resistance minimum, along sliding with best angle by the spiral case air outlet.Perfect comprehensively supercharging noise reducing plate design can make blast promote 2%, can make noise reduce by 1 decibel.Make cigarette machine spiral case perform to optimum state, compared with prior art, the utility model can promote blast, effectively reduces noise, can reach better environmental protection, energy-saving effect.
Description of drawings
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is a stereogram of the present utility model;
Fig. 3 is the structural representation of supercharging noise reducing plate.
The specific embodiment
The architecture advances of a kind of cigarette machine spiral case of the present utility model, referring to figs. 1 to Fig. 3, comprise cigarette machine spiral case body 1 and the supercharging noise reducing plate 2 that is arranged at square air outlet 11 tops of this cigarette machine spiral case body 1, this supercharging noise reducing plate 2 is the cross steel plate, constitute by the steel plate 21 and the steel plate 22 that are the cross fork, the two ends of steel plate 21 and steel plate 22 have connecting portion 211 respectively, 221, the two ends of steel plate 21 are welded in by connecting portion 211 vertical point on the pair of inner wall of square air outlet 11 of cigarette machine spiral case body, the two ends of steel plate 22 are welded in another of square air outlet 11 of cigarette machine spiral case body on the inwall by connecting portion 221 vertical point, by steel plate 21 and steel plate 22 the square air outlet 11 of cigarette machine spiral case body evenly is separated into four.
After adopting such scheme, air-flow is evenly divided into 4 in the utility model through square air outlet 11 time, when no matter which part air-flow is through air outlet after criss-cross supercharging noise reducing plate 2 rectifications blast uniform and stable, again because of being divided into fritter, area reduces to some extent, blast increases, the flow velocity of wind strengthens, after 2 rectifications of supercharging noise reducing plate, force air-flow to concentrate in order, make resistance minimum by square air outlet 11, along sliding with best angle, perfect comprehensively supercharging noise reducing plate 2 designs can make blast promote 2%, can make noise reduce by 1 decibel.Make cigarette machine spiral case perform to optimum state, compared with prior art, the utility model can promote blast, effectively reduces noise, can reach better environmental protection, energy-saving effect.

Claims (2)

1. the architecture advances of a cigarette machine spiral case, comprise cigarette machine spiral case body, it is characterized in that: also comprise the supercharging noise reducing plate in the square air outlet that is arranged at this cigarette machine spiral case body, this supercharging noise reducing plate is made of the plate one and the plate two that are the cross fork, the two ends difference vertical fixing of plate one is on the pair of inner wall of the square air outlet of cigarette machine spiral case body, the two ends of plate two respectively vertical fixing in another of the square air outlet of cigarette machine spiral case body to inwall on, by plate one and plate two the square air outlet of cigarette machine spiral case body evenly is separated into four.
