Description

[Detailed description of the invention] The present invention relates to a vehicle air conditioner, especially a thin air conditioner, which can be installed both horizontally and vertically, and can be installed on either the ceiling side or the window side of the vehicle. This relates to an air conditioner that can

Conventionally, vehicle air conditioners include a blower, an evaporator, a heater core, an air outlet, an evaporator and a heater core,
It is equipped with a drip pan, a drain pipe for discharging dehumidified water dripped onto the drip pan, etc., and the mounting position of the drain pipe is uniformly set according to the installation location of the air conditioner. For example, a ceiling-mounted air conditioner installed horizontally is installed below the drip pan.

However, if this ceiling-mounted air conditioner is installed vertically so as to face the window-side wall of a vehicle, the drain pipe will no longer perform the function of discharging dehumidified water to the outside, making it impossible to install it.

Further, in the case of a special vehicle such as a bulldozer that slopes severely during operation, dehumidified water may not be discharged from the drain pipe, and there is a risk that the dehumidified water may leak from other locations.

The purpose of this invention is to allow drain pipes to be installed in multiple directions of the air conditioner, so that dehumidified water will always be released no matter how the air conditioner is installed horizontally or vertically, or even if its angle of inclination changes. This will be described in detail below using examples.

1 and 2 are simplified configuration diagrams showing an embodiment of a vehicle air conditioner according to the present invention, FIG. 1 is a horizontally arranged state of the air conditioner, and FIG. 2 is a bottom view of FIG. 1. In each figure, inside the case 1, an intake port 2, an evaporator 3, a heater core 4, an air outlet 5, and a blower 6 are provided in order along the front direction of the vehicle, and the intake port 2 is provided with a filter 7. is fixed, and a fan 8 of the blower 6 is located at a location corresponding to this filter 7.

The blower 6, evaporator 3, and heater core 4 are almost entirely covered by a drip pan 9.

The pans 9 at the rear of the evaporator 3 and at the front of the heater core 4 are deformed so as to protrude upward, forming a portion 11 of the dish-shaped water tray. The pipe 12 protrudes, and the rear end of the pan 9 has a dish-shaped water receiver that receives dehumidified water dripping from the evaporator when the case 1 is installed vertically. Pipe 13 protrudes.

Note that the rear end wire portion 14 of the pan 9 is connected to this drain pipe 13.
is inclined in the direction of

In addition, a panel 15 for temperature and blower speed control is located at the front of the case 1.

Note that this panel 15 may be provided with an operation section for switching between outside air and inside air.

When the vehicle air conditioner having the above structure is to be mounted on the ceiling of the operator's cab of a special vehicle such as a bulldozer or shovel loader, the case 1 is screwed to the mounting bracket 16 while maintaining the horizontal state as shown in the figure.

As a result, the dehumidified water from the evaporator 3 etc. is transferred to the water receiver section 11.
This water receptacle is discharged to the outside via a drain pipe 12 extending from the section 11.

At this point, the special vehicle tilted significantly while driving, and the water pan was damaged in part 1.
Even if water from 1 flows to the rear side over the bend 10, this water is discharged through the drain pipe 13.

In addition, in order to install this vehicle air conditioner facing the window side wall of a microbus or special vehicle, install this air conditioner vertically with the air outlet 5 facing upward as shown in Figure 3. , is attached to the gap between the sheet 17 and the wall portion 19 having the window 18.

In this case, as shown in FIG. 4, a duct hole is provided in the wall 20 of the case 1 on the side where the air outlet 5 is located, and an extension duct 22 having an air outlet 21 is connected to this hole. Wind can be supplied throughout the entire length of the cabin.

According to the above configuration, even if the air conditioner is arranged vertically, the drain pipe 13 is located on the lower side and this pipe 1
Dehumidified water is released from 3.

Therefore, according to the present invention, it can be installed in either the horizontal or vertical direction, and it can be installed as is on the ceiling side or window side wall of bulldozers, microbuses, etc. without adding any special water drainage mechanism. Versatility can be increased.

Further, according to this embodiment, since the central axis of the fan 6 is installed in a direction perpendicular to the extending direction of the space A, even if the diameter of the fan 8 is increased for the purpose of increasing the air volume, the pan 9 and case 1 It is possible to maintain a thin shape without increasing the width of the vehicle, and there is no risk of narrowing the living space of the vehicle interior when it is attached to the ceiling of the vehicle interior.

In the present invention, a plurality of blowers 6 may be provided as shown in FIG.

In this case, by providing a recess 23 at the rear end of the pan 9 and attaching a drain pipe 25 to the ends of the two protrusions 24, water can be efficiently discharged when installed vertically.

In addition, in the present invention, as shown in Fig. 6, case 1
An inside air opening 2 and an outside air opening 26 are provided in the casing, and a part of the case 1 in which the inside air opening 2 is formed is made to protrude, and the inside air opening 2 and outside air opening 26 are closed with a door 27, so that inside air and outside air are You may also introduce it.

In the present invention, the extension duct 22 may be a bellows-type duct made of rubber or synthetic resin.

According to such a configuration, the duct can be extended by a desired length.

According to the present invention as explained above, there is a blower that introduces air from the intake port, an evaporator that cools the air from the blower, an outlet that blows out the cooled air, and a blower that faces one direction. The case is equipped with at least a case in which an intake port and an outlet are formed, and a drip pan that receives dehumidified water from the evaporator, and the dehumidified water that is dripped onto the drip pan when the intake port and the outlet are directed downward. Since we have provided a pipe to discharge dehumidified water and a pipe to discharge dehumidified water that drips onto the drip pan when the outlet is placed above the intake port, the air conditioner can be installed horizontally or vertically. It can be installed in a variety of special vehicles, improving versatility.
