Technical field:
The utility model relates to a kind of injection flow-guiding type fire-type house kitchen toilet exhaust duct system, it is the kitchen at dwelling house, the important component in the toilet vertical out-fall system, is a kind of exhaust duct system of collection exhaust duct body, jet nozzle, variable-pressure plate, fire resisting damper, the supporting formation of preventing air reverse flow cap; This system can be in dwelling house kitchen, toilet ventilation ventilation, Smoke prevention, fire prevention, in order to improve indoor air quality and protection occupant life property safety, be widely used for building field.
Background technology:
At present, house kitchen, toilet exhaust duct technology on traditional sense are: house kitchen toilet air discharging structure is that the single hole exhaust duct communicates with a plurality of exhaust branch pipes, exhaust duct exists smoke blowing between each layer, taint of odour, particularly exists the drawback of mutual string fire when fire in actual use, and existing version can not be controlled effectively to gas flow.In order to eliminate this drawback of exhaust duct, be provided with check (non-return) valve in the import department of exhaust duct with anti-backflow, exhaust duct has carried out remodeling several times technically, does not have thoroughly to solve the difficult problem that this is directly threatening people's lives safety all the time.
Technical scheme:
The purpose of this utility model is, a kind of injection flow-guiding type fire-type house kitchen toilet exhaust duct system is provided, air discharging structure is a rectangle diplopore air discharging structure, each layer air inlet place in the exhaust duct body is provided with variable-pressure plate and fire resisting damper assembly, changed the drawback that a plurality of exhaust branch pipes in the exhaust duct of dwelling house and full building communicate, made and do not go here and there fire when in this system, keeping not smoke blowing, not taint of odour, fire substantially.
The technical solution of the utility model is: injection flow-guiding type fire-type house kitchen toilet exhaust duct system, comprise the exhaust duct body that runs through each floor, and the exhaust duct body is a rectangle diplopore exhaust duct; Be provided with central dividing plate between two exhaust ducts, the air inlet of exhaust duct is interlayer setting alternately all; Above the exhaust duct with on the position of air inlet equal height jet nozzle and fire resisting damper assembly are being housed; Be provided with a pair of variable-pressure plate on the relevant position of the inwall both sides of exhaust duct and fire resisting damper assembly, the slit between two variable-pressure plates and the jet nozzle increases along with floor and strengthens; All do not establish variable-pressure plate at one or two layers of exhaust duct and top layer, be provided with the preventing air reverse flow cap that stretches out roofing at the top of exhaust duct; Described jet nozzle is provided with taper hollow body and hemispheric bottom, is provided with adpting flange between the exhaust branch pipe of jet nozzle and level, and the air inlet of jet nozzle dips down and tiltedly is connected with this exhaust branch pipe.
Advantage of the present utility model is:
1, native system has provided the whole good function of use of exhaust duct and auxiliary accessories, has determined advantageous environment and economic results in society.
2, the air inlet of the levels exhaust duct of dwelling house is crisscross arranged, and more helps avoiding smoke blowing, taint of odour, string fire and outdoor wind-fall to irritate phenomenon.
3, native system can apply to kitchen, toilet and other Architectural Equipment of all kinds of residential buildings widely.

The specific embodiment:
Shown in Fig. 1, Fig. 2 A to 2F, injection flow-guiding type fire-type house kitchen toilet exhaust duct system comprises exhaust duct body 1A, 1B, and its structure is the diplopore rectangle, be provided with central dividing plate 2 between two exhaust ducts, the equal interlayer of the air inlet of exhaust duct 1A, 1B is provided with alternately; Above exhaust duct 1A, the 1B with on the position of air inlet equal height jet nozzle 3 and fire resisting damper assembly 4 commonly used are being housed; Be provided with slit between a pair of variable-pressure plate 5, two variable-pressure plates 5 and the jet nozzle 3 on the both sides of the exhaust duct inwall in Fig. 2 B to 2E and the relevant position of fire resisting damper assembly 4 and increase along with floor and strengthen, all do not establish variable-pressure plate 5 at one or two layers of exhaust duct and top layer; Be provided with the preventing air reverse flow cap 6 that stretches out roofing at the top of this system.
Shown in Fig. 3 and 4, jet nozzle 3 is provided with taper hollow body 7, and its bottom 8 is a hemispherical, is provided with adpting flange 9 between the horizontal exhaust branch pipe in jet nozzle 3 and kitchen, and the air inlet 10 of jet nozzle 3 dips down and tiltedly is connected with this adpting flange 9.
The structural principle of native system is as follows; Separately become exhaust duct 1A, 1B with central dividing plate 2 between two exhaust ducts, odd number layer air inlet 10 is located at the left side, and even numbers layer air inlet 10 is located at the right.Two side in the exhaust duct is provided with variable-pressure plate 5, jet nozzle 3 and fire resisting damper assembly 4, and the structure of fire resisting damper assembly 4 wherein is a known technology; When different floors were opened smoke exhaust ventilator, flue gas formed jet by fire resisting damper assembly 4 through jet nozzle 3 in smokejack, formed the exhaust effect of multiple jets on the different height of exhaust duct; When smoke exhaust ventilator cuts out, in the slit of the both sides of jet nozzle 3 and variable-pressure plate 5, produce ejector action by the speed of the gas in the exhaust duct, jet nozzle 3 and fire resisting damper assembly 4 locate to form negative pressure, reach and effectively prevent to pour in down a chimney smoke blowing, the effect of taint of odour.Slit width between jet nozzle 3 and the variable-pressure plate 5 can be adjusted to favourable exhaust effect according to differing heights.Fire resisting damper assembly 4 is installed in and exhaust duct air inlet 10 outer sustained heights, and its function is: blade is often opened at ordinary times, and blade can be at 0～90 degree, during 70 ℃ ± 0.5 ℃ of heat detector in one minute action close blade, make regular check on for the ease of the occupant, available manual-lock and resetting also can adopt automatically controlled.
