Abstract
The utility model discloses a flue system for residence comprising a main discharge flue communicated with the flue opening on each floor. The corresponding places of the main discharge flue and the flue openings on each floor are respectively equipped with an ejection exhauster. The both sides of the main discharging flue are respectively and oppositely equipped with a splitter of circular arc; the gap between the two splitters and the ejection exhauster enlarges with the heightening of the floor on which the gap located. No splitter is equipped in the portions of the main discharge flues on the bottom layer and the top layer. The ejection exhauster is a hollow body of cone shape or streamline shape and equipped with a closed bottom and an upper opening. The space between the ejection exhauster and an air discharging outlet is equipped with connection pipes downward or horizontally connected with the flue openings from the side wall of the ejection exhauster.
Description
Technical field
The utility model relates to a kind of smokejack system of dwelling house, is meant the vertical building channel that smoke evacuation or waste gas are used especially, and it belongs to the smokejack system field of building.
Background technology
Smokejack in multistoried housing construction has three types, i.e. major-minor flue, anti-check (non-return) valve flue and the pressure swing type flue on the middle and senior level of pouring in down a chimney.Pressure swing type smokejack on the middle and senior level is the most effective smoke evacuation system of current solution house kitchen smoke pollution problem, and its exhaust is smooth and easy, not smoke blowing, not taint of odour.The kitchen fume pollution problem has just obtained good solution, thereby has improved the environment of house domestic environment and residential area greatly.But, the structure of existing multilayer smokejack on the middle and senior level but has its weakness that is difficult to overcome, because it adopts the major-minor flue structure, causes its sectional area bigger in order to satisfy essential exhaust air rate, it is bigger that flue accounts for the kitchen area space, makes that occupant and dwelling construction person are difficult to accept.
Summary of the invention
The purpose of this utility model is, a kind of smokejack system of dwelling house is provided, and it can eliminate the retardation of air curtain and the phenomenon of the taint of odour of falling the cigarette effectively, discharges fume swimmingly, can dwindle the cross-sectional area of flue again, less occupies the space in kitchen.
The technical solution of the utility model is: the smokejack system of dwelling house comprises the main smokejack that communicates with each floor exhaust opening, the exhaust opening corresponding section of main smokejack and each floor respectively is provided with a jet draught unit, and the deflector of the circular arc of two symmetries respectively is housed in its both sides.The arc surface of two deflectors is opposing and establish; Distance between two deflectors increases with the increase of the floor at its place; In the main smokejack of bottom and top layer, only jet draught unit is set and deflector is not set; Jet draught unit is a taper or fairshaped hollow body, has closed bottom and upper opening, is provided with tube connector between jet draught unit and exhaust opening, and it is dipped down tiltedly by the sidewall of jet draught unit or flatly is connected with exhaust opening.
Advantage of the present utility model is:
(1) guaranteeing on the unimpeded necessary exhaust air rate of the exhaust basis sectional area of main smokejack comparatively to be dwindled.
(2) because all induced-draft fan is shut down the static pressure in the smoke exhaust pipe exit of layer is zero or negative pressure state slightly, prevented from effectively to pour in down a chimney, smoke blowing, reduced room air pollution.
(3) check (non-return) valve need not be installed in smoke exhaust pipe.

The specific embodiment
As shown in Fig. 1 and Fig. 2 A to 2F, the smokejack system of dwelling house comprises the main smokejack 1 to 6 of each floor, and they represent 1 to 6 layer main smokejack section respectively.Opposing and the deflector 8 established of one jet draught unit 7 and a pair of garden arc is installed in every joint flue collector, and deflector 8 is divided into four kinds of models, can select corresponding model for use by the different numbers of plies, and every pair of deflector 8 is installed in the both sides of jet draught unit 7.In the main smokejack 1 and 6 of bottom and top layer, do not need mounting guiding board 8; In the 2nd layer main smokejack 2, two deflectors 8 are nearest with the spacing of the outer surface of jet draught unit 7, and gorge seam therebetween is minimum; Along with increase by two deflectors 8 of floor are far away more with the distance of jet draught unit 7, gorge seam therebetween strengthens gradually; In the 5th layer main smokejack 5, two deflectors 8 are drawn close respectively on the two side of main smokejack 5, form maximum spacing.
The operation principle of this smokejack system is as follows: when some hugs the induced-draft fan start of layer, by the jet draught unit of installing on the main smokejack exhaust outlet 97, and, flue gas is become flue gas stream in the main smokejack 1 to 6 by means of the ejector action of the natural wind speed in the main smokejack 1 to 6; The deflector 8 that is provided with on the position of each jet draught unit 7 makes main smokejack 1 to 6 dwindle circulation area in varying degrees, the flow velocity maximum that flue gas is located at " eel-like figure loudspeaker ", and according to aerodynamic principle, the static air pressure at this place reduces suddenly; Adjusting circulation gorge seam size promptly changes effluxvelocity and can make its static pressure all around reduce to zero or negative value, thereby makes the static pressure at jet draught unit 7 and exhaust opening 9 places be lower than the indoor static pressure that each floor is not started shooting, and flows backwards and can not produce to indoor flue gas.In order successfully to discharge with hugging that layer increases and the exhaust gas volumn that increases, the gorge between deflector 8 and the jet draught unit 7 is stitched width and is strengthened with the increase of floor.In the main smokejack of on the middle and senior level and high residential building, whole layers of hugging except that bottom and top layer in the floor can be divided into four groups equably, install according to the 2nd layer to the 5th layer the position of deflector 8 in the present embodiment, flow equably to reach flue gas stream, make the acceleration relay effect of playing in the whole smokejack in each layer smoke evacuation, flue gas is upwards discharged rapidly.
Shown in Fig. 3 and Fig. 3 A, be provided with a tube connector 7A between the exhaust outlet 9 of jet draught unit 7 and smoke exhaust ventilator, it is connected with exhaust outlet 9 from jet draught unit 7 is downward-sloping, therefore, it has certain siphonic effect, and is better than the smoke discharging effect of common horizontal connection tube.
