Description

[Detailed description of the invention] This invention relates to an air conditioner with an improved drain hose for draining drain water outdoors.

The indoor unit of a split type air conditioner is installed at a high place indoors, such as on a wall, so the drain water generated from the air heat exchanger of this indoor unit is led outside by a relatively long drain hose and drained. There is.

1 and 2 show a conventional indoor unit, in which an air heat exchanger 2 and a blower 3 are provided in a main body 1 to exchange heat with indoor air.

A drain pan 4 is provided at the bottom of the air heat exchanger 2, and the drain water generated from the air heat exchanger 2 is collected in the center by the drain pan 4. It is designed to be discharged to the outside through a hose 6.

However, since the drain hose 6 is entirely a flexible tube and is piped along the back surface 7 of the main body 1 to the right or left side of the main body 1 and then led outside through a window or wall, etc., the drain hose 6 is a flexible tube. A substantially horizontal portion of the drain hose 6 along line 7 hangs down due to the weight of the drain water, and the drain water may accumulate in this portion and overflow.

Therefore, a guide fitting 8 for gripping the drain hose 6 is attached to the back surface 7 of the main body 1, but this increases the number of parts, causes an increase in cost, and increases the distance between the back surface 7 of the main body 1 and the wall surface. There is this inconvenience.

This idea was devised by paying attention to the above-mentioned circumstances.The key point of this idea is that a part of the drain hose made of flexible hose is provided with a straight part that cannot be bent.
It is an object of the present invention to provide an air conditioner that can prevent a drain hose from sagging and reduce costs by reducing the number of parts.

This invention will be explained below based on an embodiment shown in the drawings.

11 in Figures 3 to 5 is the indoor unit body of a split type air conditioner, and inside this body 11 is an air heat exchanger 1.
2 and a blower 13 are provided.

A drain pan 14 is installed at the bottom of the air heat exchanger 12, and a drain port 15 is provided at the center of the drain pan 14 in the longitudinal direction.

An opening 17 is formed in the back surface 16 of the main body 11 facing the drain port 15, and one end of a drain hose 18, which will be described later, is inserted through the opening 17 and connected to the drain port 15.

This drain hose 18 is a flexible hose made of a synthetic resin material, and has connection parts 19 a at both ends.
, 19b are provided.

At one end in the longitudinal direction of the drain hose 18, that is, on the side of the connecting portion 19a, a straight portion 21 that cannot be bent is provided, leaving a bent portion 20 that is inserted into the opening 17 of the main body 1.

The length l of this straight portion 21 is approximately + the width L of the main body 11.
The drain hose 18 is installed almost horizontally along the back surface 16 of the main body 11 whether it is placed on the right side or on the left side of the main body 11.

Therefore, drain water generated from the air heat exchanger 12 during cooling operation is collected in the center by the drain pan 14 and flows from the drain port 15 to the drain hose 18.

At this time, the weight of drain water is added to the straight part 21 of the drain hose 18, but since the straight part 21 cannot be bent, the drain hose 18 does not hang down and the drain water does not accumulate, and the water is drained smoothly into the room. .

In the above embodiment, an indoor unit of a split type air conditioner has been described, but the present invention is not limited to this, and it goes without saying that the present invention can also be used in a package type air conditioner.

As explained above, this invention has a part of the drain hose with an unbendable straight part, and this straight part is piped along the back of the main body, so even if the weight of drain water is added, the drain will not drain. The hose does not hang down, and the conventional drain hose grip fitting is unnecessary.

Therefore, the cost can be reduced by reducing the number of parts, and the distance between the wall surface and the back surface of the main body can be narrowed, especially in a wall-mounted indoor unit.
