Description

[Detailed Description of the Invention] The present invention relates to an improvement of an air conditioner in a vehicle such as an automobile.

An example of an air conditioning system in a conventional truck will be explained with reference to FIG. 1, which conveniently shows an embodiment of the present invention. A windshield is disposed above the front panel, 18 is an instrument panel to which instruments (not shown) are attached, 20 is a blower of an air conditioner, and 22 is an air conditioner casing that houses the blower 20. The casing 22 includes an outside air intake 26 for taking in outside air through the air intake opening 24 of the front panel 12, and a cabin air intake (commonly known as an inside air intake) for taking in air from inside the cabin C. 28, and these outside air and inside air intake ports 26, 28 are controlled to open and close by a damper 30. Of course, air conditioning elements such as a heater core and a cooler evaporator are housed within the casing 22, but these are not shown.
Filters 32 and 34 are provided at the outside air and inside air intakes 26 and 28, respectively, to separate out dust and the like.

In the above device, when the truck is running under rain or snow, especially when the damper 30 is in the position shown by the solid line in the figure, that is, when the truck is running while ventilating by taking in outside air from the inlet 26, the opening 2 of the front panel 12
Most of the water droplets in the running wind taken in from the vehicle 4 are separated by the filter 32, but a portion inevitably enters the casing 22 beyond the filter and accumulates at the bottom of the casing 22. When the damper 30 is switched to the position shown by the dotted line in the figure for the purpose of heating or cooling while driving, water accumulated at the bottom of the casing 22 flows from the inside air intake port 28 through the filter 34 into the passenger compartment C. There was a problem in which the water penetrated the inside of the casing and wet electrical equipment, mats, etc. (not shown) installed below the casing, causing their failure and corrosion.

The present invention was devised in view of the above, and includes a gutter groove that receives water droplets dripping from the opening edge of the intake port on the peripheral edge of the filter support frame that is attached to the cabin air intake port of the air conditioner casing. The gist of the present invention is to provide an air conditioner for a vehicle, characterized in that a drain pipe for discharging water collected in the gutter groove to the outside of the vehicle interior is connected to the filter support frame.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. (Incidentally, the explanation of the matters already explained in relation to the above-mentioned conventional device will be omitted to avoid duplication.) In the present invention, the filter 34 provided at the inside air intake port 28 of the casing 22 is supported by the support frame 36. , the support frame is provided with a gutter groove 38 surrounding the filter. Further, the support frame 36 has a stepped portion 40 on the outer wall of the gutter groove at both side edges thereof, and the stepped portion is slidably fitted into the corresponding supporting groove 42 of the casing 22. Furthermore, the gutter groove 38
The drain pipe 46 slopes leftward in FIG. Through it, the same darts board 10
The vehicle compartment C passes through the space between the front panel 12 and the front panel 12.
It is open to the outside. In addition, in Figure 3, 48
5 is a sponge plate attached to the outside air intake port 26 side of the damper 30, and 50 is a sponge plate similarly attached to a portion of the damper 30 that comes into contact with the area around the inside air intake port 28.

According to the device according to the present invention described above, the damper 3
When driving in the rain with the inside air intake port 28 closed and the outside air intake port 26 open, some rainwater enters the casing 22 through the filter 32 and accumulates mainly at the bottom of the casing on the side of the damper 30. Even if it is
Next, when the damper 30 is rotated and the inside air intake port 28 is opened, the air flows from the peripheral edge of the intake port 28 into the gutter groove 38 of the filter support frame, collects in the water collection part 44, and then flows into the water drain pipe 46. It is immediately discharged from the vehicle compartment C. Therefore, water does not fall into the vehicle interior and wet the electrical equipment, mats, etc. below the casing 22, unlike in the conventional case. Note that if the watertightness of the sponge 50 is incomplete, water in the casing will flow down into the gutter groove 38 even when the damper 30 closes the inside air intake port 28, but in this case, of course, the same procedure as above applies. It is definitely discharged outside the vehicle compartment C.

As described above, the vehicle air conditioner according to the present invention receives water droplets dripping from the opening edge of the intake port on the peripheral edge portion of the filter support frame attached to the cabin air intake port of the air conditioner casing. The feature is that a gutter groove is provided, and a drain pipe for discharging water collected in the gutter groove to the outside of the vehicle interior is connected to the filter support frame, and the simple structure allows the drain pipe to be connected to the filter support frame. This is extremely beneficial as it can reliably prevent water from entering the vehicle interior.
