Abstract
Disclosed is a self-purging double functional exhaust airway. The exhaust airway 1 mainly comprises a main exhaust airway 2 and two rows of auxiliary exhaust airway 3.The main exhaust airway 2 of the hollow cavity passes through the apartment from the bottom floor to the top floor, and two rows of auxiliary exhaust airway 3 are arranged on each floor, wherein a self purger 8 is respectively arranged on the air outlet 7 of the two rows of auxiliary exhaust airway 3, and a power-extractor 9 is arranged on the opening air place out of the top floor 6. According to the utility model, even though the kitchens of certain floors are not arranged with the ventilator or the ventilators which are communicated with the same auxiliary exhaust airway don't work, the ventilators of other floors which are working or the self purger of naturally exhausting in the exhaust airway and the suction of the power-extractor on the top floor can purify the air of each floor.
Description
Technical field
The utility model relates to building ventilation smoke evacuation field device, is that a kind of dwelling house is concentrated the vertical gas pass in the exhaust system specifically.
Background technology
China city dweller lives in multilayer and the middle and high layer residential building more at present, for solving the oil smoke discharge problem, nation-building portion regulation rose in 99 years must install vertical centralized smokejack in the construction wall in lavatory, newly-built dwelling house kitchen, i.e. the gas unification that each family is discharged with smoke exhaust ventilator, exhaust fan is sent to the high-altitude through pipe special.Yet in the real life, when many smoke exhaust ventilators, exhaust fan were worked simultaneously, oil, flue gas were known from experience and are formed negative pressure in each floor generation air pressure change in the flue, occurred ' pouring in down a chimney ' phenomenon such as ' collaborate ' easily, caused secondary pollution.Be head it off, builders have installed various ' check (non-return) valves ' in flue, but effect is not satisfactory.Just make the valve block folding malfunctioning owing to the greasy dirt adhesion after often using a period of time, maintenance cost is higher.
Inventor of the present utility model has proposed utility application " The Row-Type Anti-String Anti-Intrusion Exhaust Smoke Pipeline " on October 19th, 2004, and obtains the authorization on July 20th, 2005.This is novel to provide a kind of can making to keep in the passage stablize negative pressure state, prevents smoke blowing, pours in down a chimney the self arrangement exhausting duct of phenomenon appearance.But in real life, when smoke exhaust was not opened, the user can only rely on the gravity-flow ventilation ventilation.If long-term nobody home can cause IAQ bad.
Summary of the invention
The purpose of this utility model be to provide a kind of can still can be when not moving smoke exhaust to indoor exhausting duct of taking a breath.
The utility model is achieved in that exhausting duct 1 comprises main exhausting duct 2 and the auxiliary exhausting duct 3 of two row.Main exhausting duct 2 is cylindrical body of a cavity, vertically extends through top layer from the residential building bottom and is divided into and is the first floor 4, interlude 5,6 three parts of top layer.According to its discharging air pressure the auxiliary exhausting duct 3 that two row are respectively a joint or more piece is set at every floor, whenever exhaust outlet 7 places that are listed in the auxiliary exhausting duct 3 of a joint are provided with an elf-exhaustor 8, one of them elf-exhaustor 8 communicates with the flue gas mouth of each household, another one elf-exhaustor 8 natural exhausts.Be that the roof layer goes out the roofing place draught unit 9 is set in top layer 6 upper ends.
The utility model is simple in structure, reasonable in design, with low cost.Because adjacent two layers building smoke exhaust leads to different auxiliary exhausting ducts, even smoke exhaust is not opened in the kitchen of certain layer of resident family, the suction that smoke exhaust that other floor is being worked, that be communicated with the auxiliary exhausting duct of same row produces also can help to discharge the oil smoke gas in this kitchen.All not have work even full building is communicated with the smoke exhaust of the auxiliary exhausting duct of same row, the suction of the elf-exhaustor of natural exhaust and the generation of roof draught unit also can be realized the indoor air of each floor is purified in the auxiliary exhausting duct of another row.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for the same long limit of the utility model is provided with the partial structurtes schematic diagram that two row are assisted exhausting duct;
Fig. 3 is provided with the partial structurtes schematic diagram of the auxiliary exhausting duct of row respectively for long limit of the present utility model and minor face.
Among the figure, 1 exhausting duct, 2 main exhausting ducts, 3 auxiliary exhausting ducts, the 4 exhausting duct first floors, 5 exhausting duct interludes, 6 exhausting duct top layers, 7 exhaust outlets, 8 elf-exhaustors, 9 draught units.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described;
With reference to Fig. 1,2, rectangle exhausting duct 1 comprises main exhausting duct 2 and the auxiliary exhausting duct 3 of two row.Main exhausting duct 2 is cylindrical body of a cavity, vertically extends through top layer from the residential building bottom and is divided into and is the first floor 4, interlude 5,6 three parts of top layer.Four auxiliary exhausting ducts 3 of every floor are arranged on the long limit of rectangle exhausting duct 1, that be not connected with room load-bearing metope, have an auxiliary exhausting duct 3 to offer an exhaust outlet 7 in every row, and this is equivalent to the installation hole to be provided of elf-exhaustor 8.One of them elf-exhaustor 8 communicates with the flue gas mouth of this layer resident family, another one elf-exhaustor 8 natural exhausts.The elf-exhaustor 8 that communicates with the flue gas mouth of this floor resident family separately in the adjacent two layers building is installed in respectively on the staggered auxiliary exhausting duct 3 of two row.Be that roof layer 6 goes out the roofing place draught unit 9 is set in top layer 6 upper ends.
The auxiliary exhausting duct 3 of two row described in the utility model can be separately positioned on (as shown in Figure 3), two relative growing on limits or the two relative minor faces on long limit exhausting duct 1, that do not connect with room load-bearing metope and the minor face.
The cross section of auxiliary exhausting duct 3 of the present invention can be square, arc or its combination, and bore can unanimity also can be gradual change.Bore at the auxiliary exhausting duct 3 of each floor is 10-500mm, and the distance between adjacent two the auxiliary exhausting ducts 3 of same row is not less than 0.1cm.In the practical application, above-mentioned bore and distance can be consistent or change according to each floor pressure condition.
In the practice, the elf-exhaustor 8 that communicates with the flue gas mouth of each layer resident family in the continuous multilayer floor is on the auxiliary exhausting duct 3 of same row, and the elf-exhaustor 8 that communicates with the flue gas mouth of each layer resident family in the neighbouring multilayer floor is on the staggered auxiliary exhausting duct 3 of other row.
The auxiliary exhausting duct 3 of every row described in the utility model can replace by two space bars are set, and forms similar air draft path.
