Abstract
The utility model discloses a public exhaust duct for houses, and is used for solving the problem of backward flowing of the convention exhaust duct. The exhaust duct comprises a sharing air passage and a plurality of branch air passages, wherein the branch air passages are arranged on one side of the sharing air passage and communicated with the sharing air passage; a unidirectional air door limiting the inflow of air and an axial flow fan are arranged in each branch air passage; and each unidirectional air door comprises a round frame the outer diameter of which corresponds to the inner diameter of the branch air passage, a plurality of long strips parallel to one other are fixed in the round frame from top to bottom, the upper edges of the long strips incline towards the interior of the branch air passage, the lower edges of the long strips incline towards the direction of the sharing air passage, and the upper or lower as well as the left or right projection parts of the upper and lower long strips are overlapped. The exhaust duct system enables the exhaust to be smooth and avoids the backward flowing of dirty air flow.
Description
Technical field
The utility model discloses a kind of house ancillary facility, concrete is the exhaust system of kitchen and washroom.
Background technology
At present, the building exhaust system that people live adopts public single channel usually and divides the family to connect airduct, and each resident family is connected airduct through smoke exhaust or exhaust fan and connects with the branch family, oil smoke gas and dirty waste gas are entered public single channel, and then enter in the atmosphere.Because the process through the public outside exhaust of single channel is the malleation exhaust, so exhaust resistance is very big, in order to alleviate this exhaust resistance, it is thicker that extract duct need design, and increased material cost virtually; Also have plenty of highly or receive the influence of wind direction when outdoor air pressure, extract duct not only can not exhaust, and the waste gas that other resident families discharged of common conduit pours in down a chimney into indoor on the contrary, and this phenomenon is recurrent in a lot of resident families; When outdoor wind-force is bigger, can produce very big noise in some exhaust duct in addition, though above-mentioned phenomenon causes big injury can for resident's life, its adverse effect of bringing is also annoying really.
Summary of the invention
The purpose of the utility model provides the public extract duct in a kind of house, and this extract duct has and prevents the function of pouring in down a chimney, and exhaust is smooth and easy, exhaust efficiency is high.
For realizing the foregoing invention purpose; The technical scheme that the application adopts is: the public extract duct in house; Comprise common air duct and some minutes family air flues, described minute family air flue is positioned at a side of common air duct, divides the family air flue to be communicated with shared air flue; In minute family air flue, be provided with and limit the unidirectional air door that gas flows into, and axial flow blower is arranged in a minute family air flue set inside; Said unidirectional air door; Comprise a round framework; The external diameter of this circle framework is corresponding with the internal diameter that divides the family pipeline, fixing from top to bottom some strip sheets that are parallel to each other in the circle framework, and the upper edge of strip sheet is to the lateral tilt; The lower edge tilts to the common conduit direction, up and down two strip sheets go up or down and a left side or right projection section superimposed.
The beneficial effect of the utility model: the public extract duct in the application's house, be provided with unidirectional air door in the lateral wherein, avoided dirty gas in the common conduit to pour in down a chimney in the lateral and then flow into the generation of indoor phenomenon; Also be provided with axial flow blower in addition in the lateral, the gas in the effect inferior division pipeline of blower fan can discharge smoothly, thereby has improved resident's comfort level.
Description of drawings
Fig. 1 is the structural representation of the application's extract duct.
Fig. 2 is the structural representation of unidirectional air door.
Among the figure: common air duct-1, branch family air flue-2, unidirectional air door-3, axial flow blower-4, circle framework-31, strip sheet-32.
The specific embodiment
Below in conjunction with accompanying drawing the application is further described:
By shown in Figure 1: the public extract duct in house; Comprise common air duct 1 and some minutes family air flues 2; Described minute family air flue 2 is positioned at a side of common air duct 1; Divide family air flue 2 to be communicated with, in minute family air flue 2, be provided with and limit the unidirectional air door 3 that gas flows into, and axial flow blower 4 is arranged in minute family air flue 2 set inside with shared air flue 1; Said unidirectional air door 3; By shown in Figure 2: comprise a round framework 31; The external diameter of this circle framework 31 is corresponding with the internal diameter that divides family pipeline 2, fixing from top to bottom some strip sheets that are parallel to each other 32 in circle framework 31, and the upper edge of strip sheet 32 is to a minute family pipeline tilt; The lower edge tilts to common conduit 1 direction, up and down two strip sheets 32 go up or down and a left side or right projection section superimposed.When if air-flow flows from minute family pipeline 2 directions towards common conduit 1 direction; Can discharge from the space between two strip sheets 32 of unidirectional air door 3; If but the flow direction of air-flow is towards the branch family during pipeline 2 directions from common conduit 1; 3 of unidirectional air doors will block this strand air-flow, thereby reach the purpose that prevents that air-flow from pouring in down a chimney.
