Abstract
The utility model relates to an anti-tainting air exhaust channel, which belongs to the civil building ventilating smoke exhaust field. The utility model is characterized in that a main air exhaust channel (5) is a rectangular cavity cylindrical body, a cuboid auxiliary air exhaust channel (3) is fixedly arranged in the main air exhaust channel (5), a main air exhaust channel side wall (1) is arranged on one side of the auxiliary air exhaust channel (3), a circular air inlet (4) is arranged on the inner main air exhaust channel side wall (1) of the auxiliary air exhaust channel (3), and a rectangular air exhaust channel air outlet (2) is arranged on the opposite side of the inner air inlet of the auxiliary air exhaust channel (3). The air exhaust channel ensures that the exhausted air on each floor is not tainted, the flue gas discharged from the auxiliary air exhaust channel at the lower floor is exhausted from the main air exhaust channel, the flue gas discharged from the auxiliary air exhaust channel at the current floor is also exhausted from the main air exhaust channel, according to the rule, the flue gas discharged from the auxiliary air exhaust channel from lower layer to the roof is exhausted from the main air exhaust channel. The air exhaust channel has the advantages that the structure is simple, the production and manufacture is easy, and the construction is convenient.
Description
Technical field
The utility model relates to civilian construction ventilation smoke exhaust field, and the vertical gas pass of using in the exhaust system is concentrated in lavatory, particularly a kind of dwelling house kitchen.
Background technology
China townsfolk lives in the multi-storey residential buildings more at present, for solving the oil smoke discharge problem, nation-building portion regulation rose in 99 years must install vertical centralized smoke vent in the construction wall in newly-built house kitchen, lavatory, 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, that builders have installed in flue is various ' check (non-return) valve, 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.
Summary of the invention
Technical problem to be solved in the utility model is: according to problems of the prior art, the utility model provides a kind of exhast duct, its simple structure, and cost is low, be easy to make and install, and air draft is effective.
Technical problem to be solved in the utility model realizes by following measure:
A kind of anti-taint of odour smoke blowing exhast duct, form by main exhast duct 5, auxiliary exhast duct 3, air intake 4, auxiliary exhast duct air outlet 2, it is characterized in that the be rectangle cylindrical body of cavity of main exhast duct 5, in main exhast duct 5, be installed with the auxiliary exhast duct 3 of cuboid, auxiliary exhast duct 3 one sides are exactly main exhast duct sidewall 1, circular air intake 4 is arranged on the main exhast duct sidewall 1 in auxiliary exhast duct 3, and the opposite of air intake 4 has rectangle to assist exhast duct air outlet 2 in the auxiliary exhast duct 3.
The utility model compared with prior art has following beneficial effect: the exhaust of each floor is not collaborated mutually, the flue gas that the auxiliary exhast duct of lower floor is discharged is walked from main exhast duct, the row of this layer of auxiliary exhast duct also is included into main exhast duct, the rest may be inferred to roof, there is not the dead angle in the whole exhast duct, the exhast duct system exhaust is unobstructed, and this exhast duct is simple in structure, manufacture easily, easy construction.
Description of drawings
Accompanying drawing is anti-taint of odour smoke blowing exhast duct structural representation.
Among the figure: 1. main exhast duct sidewall, 2. auxiliary exhast duct air outlet, 3. auxiliary exhast duct, 4. air intake, 5. main exhast duct.
The specific embodiment
As shown in the figure, the utility model is made up of main exhast duct 5, auxiliary exhast duct 3, air intake 4, auxiliary exhast duct air outlet 2, the be rectangle cylindrical body of cavity of main exhast duct 5, vertically extend through top layer from the residential building bottom, in main exhast duct 5, be installed with the auxiliary exhast duct 3 of cuboid, auxiliary exhast duct 3 one sides are exactly main exhast duct sidewall 1, circular air intake 4 is arranged on the main exhast duct sidewall 1 in auxiliary exhast duct 3, and the opposite of air intake 4 has rectangle to assist exhast duct air outlet 2 in the auxiliary exhast duct 3.The oil smoke that smoke exhaust ventilator in the kitchen is discharged enters in the auxiliary exhast duct 3 by air intake 4, and the oil smoke in the auxiliary exhast duct 3 enters in the main exhast duct 5 by auxiliary exhast duct air outlet 2, and the oil smoke in the main exhast duct 5 upwards is discharged to roof, finishes the smoke evacuation task.
