Description

[Detailed explanation of the idea] <Industrial application field> The present invention relates to an air conditioner.

<Conventional technology> Figure 2 is an exploded perspective view of a conventional air conditioner, and Figure 3 is an exploded perspective view of a conventional air conditioner.
The figure is a perspective view of the vicinity of a heat exchanger mounting rib of a conventional air conditioner.

The air conditioner houses a heat exchanger 20 for exchanging heat, a cross flow fan 40 for blowing air, and a drain pan 30 for receiving drain water D generated in the heat exchange cycle and discharging it to the outside of the airframe 10. It has a fuselage 10.

The heat exchanger 20 is fixed to a pair of heat exchanger mounting ribs 12 provided on a rear cabinet 11 of the body 10 by screws or the like. The heat exchanger mounting rib 12 is formed into a substantially right triangular shape, and the portion corresponding to the oblique side contains drain water D generated near both ends of the heat exchanger and attached near the apex of the heat exchanger mounting rib 12. A path 121 is formed for guiding the water to the drain pan 30.

<Problem to be solved by the invention> However, in the conventional configuration as described above, the drain water adhering to the side surface of the heat exchanger mounting rib does not drip into the water guide path of the heat exchanger mounting rib, so it is collected in the drain pan. Not done. In other words, the drain water adhering to the side surface may run down the side surface of the heat exchanger mounting rib and drip to the outside of the machine, contaminating the interior of the machine. In order to prevent this drain water from dripping into the room, it is possible to attach a heat insulating material to the side of the heat exchanger mounting rib to prevent the drain water from adhering to the side, but this increases the number of work steps.
The cost will be high.

This idea was devised in view of the above circumstances.
The purpose of the present invention is to provide an air conditioner that guides all drain water to a drain pan without increasing the number of work steps.

<Means for Solving the Problems> The air conditioner according to the present invention includes a heat exchanger, a body provided with heat exchanger mounting ribs that support the heat exchanger from both sides, and a body that is provided with a heat exchanger mounting rib that supports the heat exchanger from both sides. The heat exchanger mounting rib is provided with a first path for guiding drain water adhering to the apex of the heat exchanger mounting rib to the drain pan, and a drain pan that is attached to the side surface of the heat exchanger mounting rib. A second path for guiding the drain water to the drain pan is integrally formed.

<Function> This air conditioner cools air through a normal heat exchange cycle and blows the air out to the outside of the aircraft using a crossflow fan.

During the heat exchanger cycle, water vapor in the air condenses and adheres to the surface of the heat exchanger as drain water. This drain water travels along the surface of the heat exchanger and drips into the drain pan. In addition, drain water also adheres to the heat exchanger mounting rib to which the heat exchanger is attached. The drain water that adheres to the vicinity of the top of the heat exchanger mounting rib travels through the first path and drips into the drain pan. Further, the drain water adhering to the side surface of the heat exchanger mounting rib travels along the side surface, drips into the second path, and drips into the drain pan via the first path.

<Example> Hereinafter, an example according to the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of the vicinity of a heat exchanger mounting rib of an air conditioner according to the present invention. Note that parts and the like that are substantially the same as those of the conventional one will be described with the same reference numerals.

The air conditioner according to the present invention includes a heat exchanger 20 that performs heat exchange, a body 10 provided with heat exchanger mounting ribs 12 that support the heat exchanger 20 from both sides, and a body 10 that carries drain water D generated during the heat exchange cycle. 10, and a drain pan 30 for discharging to the outside, and the heat exchanger mounting rib 12 has a first path 121 that guides the drain water D attached to the apex of the heat exchanger mounting rib 12 to the drain pan 30; A second path 122 that guides drain water D adhering to the side surface of the heat exchanger mounting rib 12 to the drain pan 30 is integrally formed.

The aircraft body 10 has a front cabinet (not shown).
and a rear cabinet 11 to which the front cabinet is attached, and a rib 12 for attaching the heat exchanger.
is integrally formed with the rear cabinet 11.
The heat exchanger mounting ribs 12 are provided at intervals corresponding to the width dimension of the heat exchanger 20 to be mounted. That is, the heat exchanger 20 is interposed between a pair of heat exchanger mounting ribs 12 and fixed with screws or the like (not shown).
A drain pan 30 is provided below the heat exchanger 20 for discharging drain water D generated in the heat exchange cycle to the outside of the body 10. This drain pan 30 is formed in a substantially gutter shape in order to receive the drain water D. The heat exchanger mounting rib 12 is formed into a substantially right triangular shape, and the lower side thereof is cut into a substantially semicircular shape for mounting a crossflow fan 40 for blowing air. The side corresponding to the oblique side of this heat exchanger mounting rib 12 is the heat exchanger mounting rib 1
A first path 121 is provided that guides the drain water D adhering to the portion corresponding to the apex of 2 to the drain pan 30. That is, as shown in FIG. 1, a pair of protrusions 121a are provided on both sides, and the slide is shaped like a slide. Further, a second path 122 is provided inside the heat exchanger mounting rib 12 and joins the first path 121 from the middle.
This second path 122 drains the drain water D adhering to the inner side surface of the heat exchanger mounting rib 12 to the drain pan 30.
Similarly to the first path 121, the groove 122a is provided in a substantially groove-like shape.

In the drawings, reference numeral 41 is a motor that rotates the cross flow fan for blowing air, and reference numeral 31 is a discharge pipe for discharging the drain water D dripping into the drain pan 30 to the outside of the body 10.

Next, the operation of the air conditioner according to the present invention will be explained.

This air conditioner performs a normal heat exchange cycle to cool the air and blows the air out of the fuselage 10 using a cross flow fan 40.

Due to the heat exchange cycle, water vapor in the air condenses and adheres to the surface of the heat exchanger 20 as drain water D. This drain water D travels along the surface of the heat exchanger 20 and drips into the drain pan 30. Moreover, the drain water D also adheres to the heat exchanger mounting rib 12 to which the heat exchanger 20 is attached. The drain water D that has adhered to the vicinity of the top of the heat exchanger mounting rib 12 is transmitted through the first path 121 and drips into the drain pan 30 . Further, the drain water D adhering to the side surface of the heat exchanger mounting rib 12 travels along the side surface, drips into the second path 122, and drips into the drain pan 30 via the first path 121.

<Effects of the invention> The air conditioner according to the invention has a second path that also guides drain water adhering to the side surface of the heat exchanger mounting rib to the drain pan, so all the drain water can be routed through the drain pan. It can be discharged outside the aircraft. That is, unlike conventional air conditioners, drain water does not drip to the outside of the machine and pollute the interior of the machine.
