The air exhaust device has the advantages of good ventilation effect, rain-proof function and energy saving.
Description
Technical field
The utility model relates to a kind of air interchanger, particularly a kind of air exhausting device.
Background technology
Along with growth in the living standard, people are more and more higher to the requirement of indoor environment.On the one hand, increasing skyscraper is built in city, and on the other hand, the room air problem of skyscraper is severe gradually.Traditional air-conditioner is conceived to ensure indoor temperature, and air draft effect is not quite desirable, and adopts traditional air exhauster to carry out air draft, turns, so there is the problem that air exhauster energy consumption is larger because needs rely on power supply to drive air exhauster not stop transport.
Utility model content
The technical problems to be solved in the utility model is the defect that existing air exhausting device air draft effect is undesirable or energy consumption is larger, and a kind of good air draft effect, rainproof and save the air exhausting device of the energy that has is provided.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of air exhausting device, it includes at least three horizontal guide ducts, a vertical guide duct, one indoor vent pipe and a Ventilating valve, one end of each described horizontal guide duct is connected and forms a joint portion, and each described horizontal guide duct is laid in same level, described vertical guide duct is communicated with described joint portion, described vertical guide duct is sheathed on outside described indoor vent pipe, on the inwall of described vertical guide duct, be laid with some hemispherical projections, on the outer wall of described indoor vent pipe, there is the suitable hemispherical groove of some and described hemispherical projections, described vertical guide duct can rotate and fix around 360 °, the axis of described indoor vent pipe, one Ventilating valve is installed in described indoor vent pipe, for controlling the switching of indoor vent pipe.
Preferably, on described horizontal guide duct, be fixed with rain visor, described rain visor is fixed on the upper edge of the other end that described horizontal guide duct is not connected with other horizontal guide ducts.This makes rainwater be difficult for entering in horizontal guide duct.
Preferably, the quantity of described horizontal guide duct is three.
Preferably, the angle between described horizontal guide duct is 120 °.
Preferably, on described indoor vent pipe, an air extractor is installed.Air extractor can be extracted into indoor air in indoor vent pipe, strengthens exhaust effect.
Preferably, described horizontal guide duct adopts stainless steel.Can make horizontal guide duct there is better rust-proof effect.
Preferably, described horizontal guide duct surface scribbles protective coating.Can make horizontal guide duct there is better rust-proof effect.
Positive progressive effect of the present utility model is: make air exhausting device have good air draft effect, rainproof and save the energy.

Detailed description of the invention
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
Embodiment
Understood incorporated by reference to Fig. 1, Fig. 2, a kind of air exhausting device, it includes three horizontal guide ducts 1, vertical guide duct 2, an indoor vent pipe 3 and a Ventilating valve 4.Described horizontal guide duct 1 adopts stainless steel, and surface scribbles protective coating.On described horizontal guide duct 1, be fixed with rain visor 5, described rain visor 5 is fixed on the upper edge of the other end that horizontal guide duct 1 is not connected with other horizontal guide ducts 1.One end of each horizontal guide duct 1 is connected and forms a joint portion, and each horizontal guide duct 1 is laid in same level, and the angle between described horizontal guide duct 1 is 120 °.Described vertical guide duct 2 is communicated with described joint portion, described vertical guide duct 2 is sheathed on outside described indoor vent pipe 3, on the inwall of described vertical guide duct 2, be laid with some hemispherical projections, on the outer wall of described indoor vent pipe 3, have the suitable hemispherical groove of some and described hemispherical projections, described vertical guide duct 2 can rotate and fix around 360 °, the axis of described indoor vent pipe 3.On described indoor vent pipe 3, an air extractor is installed, indoor air can be extracted in vertical guide duct 2, accelerate scavenging period.One Ventilating valve 4 is installed, for controlling the switching of indoor vent pipe 3 in described indoor vent pipe 3.
This air exhausting device is generally placed on high level and high-rise building Zhongting roof, wherein the axis direction of a horizontal guide duct can be consistent with local wind direction, so just can increase the natural ventilation rate in this horizontal guide duct, and then can take away more room airs, reduce more mechanical exhaust energy consumption.This air exhausting device is used for reference the partial pressure properties of three-way device, when the air-flow that a horizontal guide duct is come in enters after two other horizontal guide duct, air-flow pressure reduces, thereby room air is flowed from the lower horizontal guide duct of trend air pressure, the energy consumption while having reduced traditional air exhauster operation.The direction of the horizontal guide duct of described air exhausting device also can be arranged by many group different directions, its gravity-flow ventilation is maximized.Ventilating valve can be closed in the situation that it does not need air draft.
Although more than described detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and amendment all fall into protection domain of the present utility model.
