Abstract
The utility model relates to a kind of exhaust duct of housing construction, particularly relates to a kind of anti-crossing smell air channel.Anti-crossing smell air channel on prior art basis, is carried out technological improvement and combines the overall exhaust system of the housing construction formed.It comprises the exhaust duct of housing construction.The exhaust duct of housing construction forms female air channel, anti-crossing smell air channel by female air channel, sub-air channel, kitchen guarding's exhaust equipment, thermal-arrest pulls out wind metal drum and unpowered blast cap is formed.Anti-crossing smell air channel has hot pressing and positive/negative-pressure two ponderomotive force, and improve housing construction exhaust duct and pull out wind and air draft ability to outdoor, zygote busbar air flue solves in each layer unit resident family of housing construction and mutually alters taste problem.Its structure is simple, is convenient to implement, and construction cost is low, is a kind of desirable housing construction exhaust passage.
Description
Technical field
The utility model relates to a kind of house exhaust passage, particularly relates to a kind of anti-crossing smell air channel.
Background technology
In housing construction, between Ge Ceng resident family, exhaust duct is communicated with, and there will be the problem of mutually altering taste between kitchen guarding or resident family when exhaust duct air draft scarce capacity.Taste altered by exhaust duct, is the problem that indoor environmental quality needs solution badly always.At present, the technical scheme solving house exhaust passage anti-crossing smell mainly contains following three kinds of forms, and one is install anti-air-return valve at resident family's ventilation opening; Two is that exhaust duct is arranged to primary and secondary exhaust duct; Three is arrange unpowered blast cap at exhaust duct exit opening.But, with regard to above-mentioned every technical scheme, there is shortcoming all separately:
One, anti-air-return valve is that of installing additional in each layer air inlet of single tube flue makes flue gas to the equipment of flue one-way movement, and the drag effect of anti-air-return valve can reduce air draft ability, makes self peculiar smell between kitchen guarding or resident family discharge not smooth;
Two, each layer flue is made the exhaust passage of different cross section, this exhaust passage lower floor flue is by primary and secondary flue gas, and air draft ability in lower exhaust road is subject to upper strata impact and reduces, and time serious, can produce flue gas and pour in down a chimney between each layer kitchen guarding or resident family;
Three, unpowered blast cap is that the nature nature wind speed that utilizes installed in the outlet of roof exhaust duct promotes the equipment that air draft effect is played in the rotation of blower fan turbine, this equipment exhaust smoke evacuation ability when outdoor wind-force is not enough cannot meet design requirement, and can produce equally between kitchen guarding or resident family and alter taste problem.
Utility model content
The purpose of this utility model wants the deficiency of customer service prior art, provides a kind of house exhaust passage exhaust capacity strong, can avoid the anti-crossing smell air channel that peculiar smell between kitchen guarding, resident family is ganged up mutually.
The purpose of this utility model can realize.The utility model anti-crossing smell air channel comprises the exhaust duct of housing construction, the feature in the utility model anti-crossing smell air channel is: the exhaust duct of described housing construction forms female air channel, the sub-air channel be communicated with kitchen guarding's exhaust equipment of each layer unit resident family is respectively equipped with in described female air channel, the air outlet in all sub-air channels all collects in the flowing lumen in described female air channel, described female air channel connects a thermal-arrest and pulls out wind metal drum in the exit of building roof, described thermal-arrest pulls out on wind metal drum and installs unpowered blast cap, described female air channel, sub-air channel, kitchen guarding's exhaust equipment, thermal-arrest pulls out wind metal drum and the combination of unpowered blast cap forms the overall exhaust passage system of house.
The utility model anti-crossing smell air channel difference from prior art be the utility model anti-crossing smell air channel by female air channel, sub-air channel, kitchen guarding's exhaust equipment, thermal-arrest pulls out wind metal drum and unpowered blast cap is formed.Anti-crossing smell air channel of the present utility model on prior art basis, is carried out technological improvement and combines the overall exhaust system of the house formed.Anti-crossing smell air channel has hot pressing and positive/negative-pressure two ponderomotive force, and improve exhaust duct and pull out wind and air draft ability to outdoor, zygote busbar air flue solves in each layer unit resident family of housing construction and mutually alters taste problem.Its structure is simple, is convenient to implement, and construction cost is low, is a kind of desirable housing construction air exhaust passage.
Below in conjunction with accompanying drawing, anti-crossing smell air channel of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation in the utility model anti-crossing smell air channel.
Detailed description of the invention
As shown in Figure 1, anti-crossing smell air channel of the present utility model is the technological improvement and combination carried out on prior art basis.The utility model anti-crossing smell air channel comprises the exhaust duct of housing construction.In the utility model anti-crossing smell air channel, the exhaust duct of housing construction forms female air channel 1, is respectively equipped with the sub-air channel 3 be communicated with kitchen guarding's exhaust equipment 2 of each layer unit resident family 6 in female air channel 1.The air outlet in all sub-air channels 3 all collects in the flowing lumen in described female air channel 1.Female air channel 1 connects a thermal-arrest and pulls out wind metal drum 4 in the exit of building roof, thermal-arrest pulls out on wind metal drum and installs unpowered blast cap 5.Female air channel 1, sub-air channel 3, kitchen guarding's exhaust equipment 2, thermal-arrest pull out wind metal drum 4 and the overall exhaust system of unpowered blast cap 5 combination formation house.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
