Description

[Detailed description of the invention] In the indoor unit 1' of the conventional separate air conditioner, as shown in FIG. A drain pan 4' is installed below the exchanger 2', and the drain from the drain pan 4' is led out to the outside through a drain hose 5' that forms the connection part of the extended drain pipe. In this type of unit, the auxiliary pipe 3' was led out separately and the outer periphery of the auxiliary pipe 3' was surrounded by a heat insulating material 7, but in this type of unit, the indoor unit 1' was connected to the wall. When installing, a through hole must be formed in the wall surface, and the auxiliary pipe 3' surrounded by the above-mentioned heat insulating material 7 and the drain hose 5' must be bundled with string, tape, etc. and inserted into the through hole. Not only does it take time to insert the pipe into the pipe, the through hole must be made relatively large, and a gap is created between the through hole and the auxiliary pipe 3' and the drain hose 5', resulting in an unsightly appearance. There was.

The present invention has been devised to eliminate the above-mentioned drawbacks and will be explained in detail below with reference to an embodiment shown in the drawings.

Reference numeral 1 denotes an indoor unit in the form of a rectangular box, which is provided with an indoor heat exchanger 2, an auxiliary pipe 3 such as a refrigerant pipe, and a drain pan 4 installed below the indoor heat exchanger 2.

5 is a connecting portion 4a formed in the drain pan 4.
The drain hose is fitted into a hollow cylinder with a relatively large diameter, and the auxiliary pipe 3 is inserted through the inside of the drain hose. This auxiliary pipe 3 passes through the upper part of the drain hose 5 so as not to come into contact with the drain from the drain pan 4. Further, a connecting portion 6 for connecting an extended drain pipe (not shown) is formed at the lower end of the drain hose 5.

Therefore, according to the present invention, when installing the indoor unit 1 on a wall, the drain hose 5 is inserted into a through hole (not shown) formed in the wall, and the indoor unit 1 is attached to the wall using appropriate mounting brackets. By doing so, the assembly work can be simplified without requiring the work of putting together the auxiliary pipe 3 and the drain hose 5 or the work of sealing the through holes as in the conventional case. Also, when connecting the extension drain pipe,
It is sufficient to simply connect the extension drain pipe to the connection part 6 at the tip of the drain hose 5 inserted through the through hole.

As described above, the present invention provides an indoor unit for a separate air conditioner equipped with an indoor heat exchanger, auxiliary pipes such as refrigerant pipes, and a drain pan installed below the indoor heat exchanger. This is because a relatively large diameter drain hose is provided to lead the drain to the outside, an auxiliary pipe is inserted into this drain hose, and a connection part for an extended drain pipe is formed at the lower end of the drain hose. Not only is it extremely easy to insert the through hole formed in the wall, but the diameter of the through hole can also be smaller than before, and the part of the auxiliary pipe that passes through the drain hose is provided with a heat insulating material. Since there is no need to enclose it, material costs can be reduced and costs can be reduced, which is a remarkable effect.
