Abstract
The utility model relates to a combined central exhaust pipe which can centrally exhaust waste gas in a house building, comprising a mother flue 1, an upper son flue 2, a lower son flue 3, a gas inlet 4 and a gas outlet 5. The utility model is characterized in that the gas inlet on the exhaust pipe is communicated with the upper son flue, the upper end of the upper son flue is in butt joint with the lower end of the lower son flue in the upper floor exhaust pipe of the house, and the gas outlet on the lower son flue is communicated with the mother flue. A waste gas exhaust system in the house building is composed of a group of combined central exhaust pipes, a range hood, a check valve and a wind cowl. The number of the combined central exhaust pipes is equal to the number of the house floors, the pipe length is same with the standard height of the house floors, the combined central exhaust pipes are vertically arranged, and the pipes are in butt joint. The waste gas exhaust system in the house building solves the mutual gas-blowby and flavor-blowby phenomena between floors.
Description
The utility model relates to the vertical extract duct in a kind of residential building, and particularly waste gas concentrates the primary-secondary type in the exhaust system to concentrate stack in the residential building.
In the market, mainly contain three kinds of model residential buildings and concentrate exhaust uptake, promptly main flue, single hole flue, the pressure swing type flue paid.The main flue of paying is not one-shot forming owing to intermediate section dividing plate in the pipeline is connected with the flue pipe outer wall, the junction is easy to generate the slit, the masters of two joint flue joints pay flue and misplace easily, have lost the main flue of paying and have answered role, cause between each floor kitchen mutually gas blowby to scurry the flavor phenomenon.Single hole flue indoor exhaust air directly is discharged in the flue, relies on flap valve control return-air, because that the flap valve valve block is stained with easily is sticking greasy, valve block is not closed completely, and gas blowby promptly takes place between each floor kitchen mutually scurry the flavor phenomenon.The pressure swing type flue mainly exists floor space big, and the manufacturing process complexity is installed inconvenience, only is applicable to low residential building.
The purpose of this utility model provides a kind of concentrated stack of primary-secondary type that waste gas in the residential building can be concentrated discharging.
The technical solution of the utility model is that design one profit comprises one group and equates with the residential building number of plies, the primary-secondary type that pipe range is identical with residential building standard floor height is concentrated stack, the tube and tube vertical butt joint, establish female flue, last sub-flue, following sub-flue in the pipe, go up on the sub-flue and have air inlet port, air inlet port is connected with flap valve, and the flap valve other end is connected with the range hood gas outlet, and the stack of uppermost storey docks with blast cap tube connector on the roof.
The utility model advantage is to establish sub-flue, female flue in the concentrated stack of primary-secondary type, the one-shot forming of primary and secondary flue, kitchen flue gas concentrates from primary-secondary type by flap valve that air inlet port enters sub-flue on the stack, gas outlet, sub-flue upper end enters female flue under concentrating in the stack by primary-secondary type in the last floor kitchen again, discharges outdoor again.Take this structure can prevent that not only flue gas from pouring in down a chimney phenomenon, make kitchen flue gas discharge the open air smoothly, and the order air-flow is lived female flue and is flowed smooth and easy, the interference of forced-ventilated wind when not opened by every pull-up smoke exhaust, so concentrate the exhaust duct section to amass under square one, primary-secondary type concentrates the stack capacity all bigger than the flue gas amount of other specification.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is Fig. 1 vertical view of the present utility model.
Comprise female flue 1 among the figure, go up sub-flue 2, sub-flue 3, air inlet port 4, gas outlet 5 down, it is characterized in that: the air inlet port 4 on the stack is communicated with last sub-flue 2, go up on sub-flue upper end and the dwelling house floor stack interior under sub-flue 3 lower ends right
Connect, gas outlet 5 is communicated with female flue 1 on the following sub-flue.
During installation, one group equates that with the residential building number of plies pipe range is identical with residential building standard floor height, the vertical primary-secondary type that is provided with is concentrated stack, the tube and tube butt joint, and the mutual structure of female flue is logical in the pipe, go up sub-flue and be communicated with following sub-flue, high floor stack docks with blast cap tube connector on the roof.
Open when range hood, open flap valve, waste gas enters sub-flue 2 from air inlet port 4, enters female flue 1 by gas outlet 5 on the following sub-cigarette logical 3 in the last floor stack, discharges outdoor by blast cap.Waste gas is concentrated exhaust system in the residential building of the utility model and range hood, flap valve, the supporting composition of blast cap, has solved interior toxic emission of residential building and the mutual gas blowby of each floor gap and has scurried the flavor phenomenon, helps to improve dwelling environment.
