Abstract
The utility model relates to a new wind intake water-proof device of air-conditioning unit, especially a new wind intake water-proof device suitable for top intake vehicle air conditioner, belonging to the technical field of track transportation vehicle air-conditioning apparatus. The structure of the utility model includes a water-proof cavity; a new wind intake connected with the air is opened in the wall of the water-proof cavity; one side of the water-proof cavity is connected with an evaporating cavity of the air-conditioning unit through a new wind valve; the bottom of the water-proof cavity is provided with a drain hole, wherein a flashing board that prevents the rain from entering the evaporating cavity along with the new wind is provided between the new wind valve and the new wind intake. The special design of the flashing board of the utility model can effectively prevent the rain from entering the evaporating cavity along with the new wind so as to greatly improve the water tightness of the whole machine.
Description
Technical field
The utility model relates to the new wind air inlet of a kind of air-conditioning unit water-tight device, and particularly a kind of new wind air inlet water-tight device that adapts to top air intake vehicle air conditioning belongs to the rail traffic vehicles air conditioner technical field.
Background technology
The air intake vehicle air conditioning waterproof construction design of existing top is made of new wind admission port and discharge port, the rainwater that enters with new wind at first directly is discharged to outside the air-conditioning unit through discharge port behind the process fresh wind port grid, the remarkable shortcoming of this waterproof construction is easily to enter the evaporation cavity of a/c system with new wind in the new wind intake process moderate rain water capacity, and then increases the possibility of rainwater through return air channel or supply air duct injection vehicular traffic passenger area.
The utility model content
The utility model technical issues that need to address provide the new wind air inlet of a kind of air-conditioning unit water-tight device, can prevent effectively that rainwater from entering evaporation cavity, improve the water tightness of rail traffic vehicles air-conditioning.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The new wind air inlet of a kind of air-conditioning unit water-tight device, comprise in its structure, anti-water cavity, anti-water cavity wall is offered the new wind admission port that is communicated with atmosphere, anti-water cavity one side is communicated with the evaporation cavity of air-conditioning unit by new air-valve, anti-water cavity bottom is provided with drain gutter, is provided with between new air-valve and new wind admission port and can prevents that rainwater from entering the rain visor of evaporation cavity with new wind.
The further improvement of the technical solution of the utility model is: new wind admission port is arranged on the top of anti-water cavity.
Because the technological advance that has adopted technique scheme, the utility model to obtain is:
The utility model structure can effectively stop rainwater to enter evaporation cavity with new wind owing to increased the particular design of rain visor, makes the water tightness of complete machine significantly improve.
Description of drawings
Fig. 1 is the new wind air inlet of an a kind of air-conditioning unit water-tight device structural representation;
Wherein: 1, new air-valve, 2, new wind admission port, 3, rain visor, 4, drain gutter, 5, anti-water cavity, 6, evaporation cavity.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
As shown in Figure 1, the utility model structure comprises, anti-water cavity 5, the new wind admission port 2 that is communicated with atmosphere is offered at 5 tops, chamber that discharge water, anti-water cavity 5 passes on left the evaporation cavity 6 that new air-valve 1 is communicated with the air-conditioning unit, and anti-water cavity 5 bottoms are provided with drain gutter 4, above new air-valve 1 rain visor 3 is set.
When the air-conditioning unit needed new wind, new air-valve 1 was opened, and at first through the top of new wind admission port 2 arrival rain visors 3, rain visor 3 forces new wind to detour to rainwater, thereby stops rainwater directly to enter evaporation cavity 6 by new air-valve 1 with new wind with new wind; Rainwater flows to anti-water cavity 5 bottoms again after the upper surface of rain visor 3 converges, be discharged from unit through drain gutter 4, and the rainwater quality after converging increases, and is difficult for being brought in the evaporation cavity 6 by air-flow; When not needing new wind as the air-conditioning unit, new air-valve 1 is in closed condition, has thoroughly stopped the possibility that rainwater enters unit evaporation cavity 6.
Claims (2)
1, the new wind air inlet of a kind of air-conditioning unit water-tight device, comprise in its structure, anti-water cavity, anti-water cavity wall is offered the new wind admission port that is communicated with atmosphere, anti-water cavity one side is communicated with the evaporation cavity of air-conditioning unit by new air-valve, anti-water cavity bottom is provided with drain gutter, it is characterized in that: be provided with between new air-valve and new wind admission port and can prevent that rainwater from entering the rain visor of evaporation cavity with new wind.
2, the new wind air inlet of a kind of air-conditioning unit according to claim 1 water-tight device is characterized in that described new wind admission port is arranged on the top of anti-water cavity.
