The specific embodiment
To combine the accompanying drawing of the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, all other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belong to the protection domain of the utility model.
Like Fig. 1 and shown in Figure 4, comprise main exhast duct 02 and a plurality of auxilliary exhast ducts 03 according to the exhaust system of the utility model exemplary embodiment, main exhast duct 02 has main air inlet 021, and auxilliary exhast duct 03 has auxilliary air intake 031.Exhaust system is arranged in the construction wall 01 basically vertically, and main air inlet 021 is arranged at surface of wall with auxilliary air intake 031, and is connected with indoor, and main air outlet 022 is connected with outdoor through roof blast cap 1.
Because the high extent between two air intakes, directly have influence on the size of the draft at air intake place, promptly the discrepancy in elevation between two air intakes is more little, and the draft at air intake place is more little, otherwise big more.Therefore; In order to reach more satisfied air draft effect, and strengthen the draft at air intake place, construction wall 01 in can be arranged side by side the twice exhast duct; The air intake of one exhast duct is connected with the indoor of odd-level, and the air intake of another road exhast duct is connected with the indoor of even level.
According to the utility model exemplary embodiment, for easy for installation, simple, main exhast duct 02 comprises main air draft elbow 7, more piece master's exhaust duct 2 and a plurality of tee piece 6.Two adjacent main exhaust ducts 2 are connected with two master ports of tee piece 6, and main exhaust duct 2 bottom is connected with main comb windbend head 7.Auxilliary exhast duct 03 comprises auxilliary exhaust duct 3 and auxilliary exhaust duct elbow 4; Auxilliary exhaust duct 3 is connected with an end of auxilliary exhaust duct elbow 4 and in main air duct 02, upwards extends certain-length; The other end of auxilliary exhaust duct elbow 4 stretches out from a port of tee piece 6, forms auxilliary air intake 031.
Auxilliary exhast duct elbow 4 cooperates with nut 5 from the extension of a port of tee piece 6; For example; Can external screw thread be set at the extension of auxilliary exhaust duct elbow 4, like this can through with being threaded of nut 5, said auxilliary exhast duct 03 is fixed in the said main exhast duct 02.Be provided with the steel gauze in the nut, its objective is to prevent that mosquitos and flies is in the exhast duct inlet chamber.
Ordinary circumstance gets in the main exhast duct 02 for fear of rain, snow, dust etc., also is provided with blast cap 1, and blast cap 1 is installed on the port of the main exhaust duct 2 that is positioned at the top.
In addition, for fixing more firm between each component, between blast cap 1 and the main exhaust duct 2, between main exhaust duct 2 and the tee piece 6, between main exhaust duct 2 and the main air draft elbow 7, assist between exhaust duct 3 and the auxilliary exhaust duct elbow 4, bond through special glue.Can certainly adopt to be threaded, as long as can reach identical technique effect.
According to the ventilation system of the utility model, the flow path of air-flow is: for one deck, gas flows into main exhast duct 02 after getting into main air inlet 021, continues to rise to roof blast cap 1 and discharges; More than one deck, after gas gets into auxilliary air intake 031, flow into main exhast duct 02 through auxilliary exhast duct 03, continue to rise to roof blast cap 1 and discharge.
According to the exemplary embodiment of the utility model, the exhaust system of the utility model can adopt the PVC material to form.In addition, though be the exhaust system that example is described the utility model with the washroom that is applied to multi-storey building, the exhaust system of the utility model can be applied in the tier building of other types.
Those skilled in the art are arranged at construction wall 01 inside with said exhast duct, construct simultaneously with building body, and said air intake is arranged on the washroom inner wall surface.For example, said exhaust system is arranged in the constructional column or is arranged in the construction wall 01 with reference to the form of constructional column, both guaranteed that the difficulty of construction of construction wall 01 can not increase, also can not influence the overall structure in house.
Because the exhaust system that the utility model provided has adopted main exhast duct 02; And main exhast duct 02 is arranged in the construction wall 01; Therefore with respect to background technology; When having avoided reserving installing hole with reinforcing bar around breaking off in the pre-position to the both sides in precalculated position or with reinforcing bar, and avoided picking the concrete floor around the cutter installing hole, improved the intensity of concrete floor relatively.
Because main exhast duct 02 is arranged in the construction wall 01, has avoided in the prior art installing hole place being carried out waterproofing work, and then has reduced the phenomenon of percolating water; Also, reduced the difficulty of plastering, increased indoor usable floor area because main exhast duct 02 is arranged in the construction wall 01.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
