Description
Technical field
The utility model relates to a kind of drainage arrangement, relates in particular to a kind of rainwater that prevents and gathers the drainage arrangement that enters automotive air-conditioning system.
Background technology
Usually cavity is open type (being convenient to draining) before the air conditioning for automobiles discharge outlet, cavity has following defective before this open type air-conditioning discharge outlet: if discharge outlet is excessive, have the contaminant particles such as dust that take up in too much vehicle exhaust and the driving process and enter passenger compartment, cause passenger's discomfort by air-conditioning system; If discharge outlet is too small, then can influence drainage effect, may cause ponding in the preceding cavity of air-conditioning air inlet, and ponding is easy to enter in the air-conditioning box and cause motor to damage.Therefore, the coach work teacher is difficult to take into account the position and the size of air-conditioning air inlet when design air-conditioning air inlet.
U.S. Pat 3701560 and Chinese patent CN200974558 disclose a kind of design of discharge outlet respectively, but these schemes more complicated but also reduced the effective area of discharge outlet all also is unfavorable for rapid draining.
In sum, be necessary to design a kind of drainage arrangement of automotive air-conditioning system to overcome the defective of prior art in fact.
The utility model content
The purpose of the drainage arrangement of automotive air-conditioning system of the present utility model is: a kind of drainage arrangement with automotive air-conditioning system of certain sealing is provided, this drainage arrangement can prevent that rainwater from gathering, help the smooth draining of automotive air-conditioning system, can stop the contaminant particles such as dust that take up in vehicle exhaust and the driving process to enter passenger compartment again by air-conditioning system.
In order to achieve the above object, a kind of drainage arrangement of automotive air-conditioning system is provided is like this design to the utility model:
A kind of drainage arrangement of automotive air-conditioning system, it comprises air-conditioning drain chamber and the elastic cover plate that links to each other with described air-conditioning drain chamber, described air-conditioning drain chamber comprises sidewall and two openings, one of them opening connects air-conditioning system, another opening connects described elastic cover plate, described sidewall comprises side and base, and described elastic cover plate comprises cover board body and the fixed part that is connected with a side elasticity of described cover board body.
As preferred implementation, the angle between described fixed part and the described cover board body is 90 °, and fixed part is connected with the side elasticity of described air-conditioning drain chamber sidewall.
As preferred implementation, described fixed part and described cover board body are on the same horizontal plane, and fixed part is connected with the base elasticity of described air-conditioning drain chamber opening.
As preferred implementation, the light heat-resisting elastic sheet rubber that described elastic cover plate is formed in one.
The existing certain sealing of the drainage arrangement of automotive air-conditioning system of the present utility model, can stop the contaminant particles such as dust that take up in vehicle exhaust and the driving process to enter passenger compartment by air-conditioning system, can prevent that again rainwater from gathering, help the smooth draining of automotive air-conditioning system.Simultaneously this scheme also have simple in structure, cost low and to complete vehicle weight do not have substantially the influence characteristics.

The specific embodiment
Please in conjunction with consulting Fig. 1, Fig. 2, the drainage arrangement of automotive air-conditioning system of the present utility model comprises air-conditioning drain chamber 10 and the elastic cover plate 12 that links to each other with described air-conditioning drain chamber 10.Described air-conditioning drain chamber 10 comprises sidewall and two openings, and one of them opening connects air-conditioning system, and another opening connects described elastic cover plate 12.Described elastic cover plate 12 comprises cover board body 120 and the fixed part 122 that is connected with a side elasticity of described cover board body 120.Described sidewall comprises side 100 and base 102.
In first embodiment of the present utility model, angle between described fixed part 122 and the described cover board body 120 is roughly 90 °, and fixed part 122 is connected with side 100 elasticity of described air-conditioning drain chamber 10 sidewalls, and described cover board body 120 shelters from the opening of described air-conditioning drain chamber 10 just.Preferably, described elastic cover plate 12 is selected integrated light heat-resisting elastic sheet rubber for use.
In second embodiment of the present utility model, described fixed part 122 is on the same horizontal plane with described cover board body 120, and fixed part 122 is connected with base 102 elasticity of described air-conditioning drain chamber 10 openings, and described cover board body 120 shelters from the opening of described air-conditioning drain chamber 10 just.Preferably, described elastic cover plate 12 is selected integrated light heat-resisting elastic sheet rubber for use.It will be understood by those skilled in the art that the utility model can also establish, count the elastic cover plate 12 of respective shapes specially at difform drain chamber 10.
Briefly introduce the operation principle of described elastic cover plate 12 below.When described elastic cover plate 12 does not have water and air-conditioning not to open in drain chamber 10 yet, there is a normal pressure in the drain chamber 10, though described elastic cover plate 12 is not fine in deadweight effect lower seal effect, but under the effect of this normal pressure, tail gas, contaminant particle also are difficult for entering in the passenger compartment; When in drain chamber 10, not having water and air-conditioning to open, there is a negative pressure before the air-conditioning air inlet in the cavity, described elastic cover plate 12 is in the closed condition of adsorbed close under this negative pressure effect, its sealing effectiveness is good, prevented vehicle effectively under each transport condition, the waste hot gas in the enging cabin enters air-conditioning system, can effectively reduce the air-conditioning intake air temperature, thereby strengthen the refrigerating capacity of air-conditioning system, can also weaken from discharge outlet entering car external noise in the passenger compartment simultaneously.When in the drain chamber 10 water being arranged, elastic deformation takes place in described elastic cover plate 12 under the effect of current gravity, cover board body 120 is opened automatically and is carried out draining, and this moment, drain chamber 10 was full of by water and bubble thereof, played the effect of natural block contaminants particle and cool exhaust hot air.
The drainage arrangement of automotive air-conditioning system of the present utility model does not need to reduce the size of drain chamber 10 openings, and the opening angle of described elastic cover plate 12 also can reach 90 degree nearly, so also can not influence the drainability of discharge outlet, can prevent that under big rainfall situation rainwater gathers and enters the motor damage that automotive air-conditioning system causes.The drainage arrangement of automotive air-conditioning system of the present utility model drainage effect in 40 continuous 8 minutes gallon per minute rain drop tests is good.
