Abstract

PURPOSE:To simply, efficiently inspect drain discharge of an air conditioner installed at a high place such as a ceiling, etc., or a place having a small service space. CONSTITUTION:When generated drain water B is fed into a transparent drain hose 6 through a drain pump 5, it is identified by a transparent peep hole 9 of a service panel 10 to inspect an operation of the pump. When adhered dye adhered to an outer frame of the pump and solid dye arranged on a drain pan are dissolved and solution liquid is fed into the hose through the pump, it is identified via the hole of the panel to inspect the operation of the pump. Further, a rotation of an impeller to be rotated by a water flow by the hose is identified via the hole of the panel to inspect the operation of the pump.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain discharge inspection device for an air conditioner for inspecting the discharge condition of drain water of the air conditioner.

[0002]

2. Description of the Related Art In recent years, there have been air conditioners installed in high places such as ceilings (for example, a ceiling-embedded air conditioner).
In the case of an air conditioner installed at such a high place, if drain water is not discharged smoothly, not only will the air conditioner itself malfunction due to overflow from the drain pan, but also the drain water on the floor surface. There is a problem that the item will fall.

Therefore, it is necessary to eliminate the above-mentioned problems by inspecting the drain water discharge condition when the air conditioner is installed.

Hereinafter, the conventional drain discharge inspection apparatus for an air conditioner will be described with reference to the drawings.

FIG. 5 (a) is a front sectional view of the entire conventional drainage discharge inspection device for an air conditioner. In FIG. 5 (a), A is an air conditioner, 1 is a casing, 4 is a drain pan, B is a drain water, 5 is a drain pump, 6 is a transparent drain hose, and 8 is a heat exchanger. From this, it is out of the machine, 7 is a drain pipe, C is a top plate, and D is an inspection port.

FIG. 5 (b) is a side sectional view of FIG. 5 (a). Figure 5
In (b), 2 is a side panel, and 3 is a screw for fixing the side panel.

The operation of the drain discharge inspection device for an air conditioner configured as described above will be described.

First, as a conventional inspection method, an air conditioner A generally installed in a high place such as a ceiling is used.
Supply water to the drain pan 4 using a cup, etc.
Then, the side panel 2 was opened, and the discharge condition of the drain water B from the drain pump 5 to the transparent drain hose 6 was inspected.

[0009]

However, in the above-mentioned conventional structure, since the side panel 2 is opened, a considerable working space is required in the ceiling or the like, and the fixing screw 3 or the like must be removed. There is a drawback in that it takes a lot of time and effort just to perform the drain discharge inspection in one air conditioner.

The present invention solves the conventional problems, and provides a drain discharge inspection device for an air conditioner, which is capable of efficiently performing a drain discharge inspection installed in a high place such as a ceiling. That is the purpose.

[0011]

In order to achieve the above object, the present invention firstly provides a service panel provided with a transparent peephole in the vicinity of a drain pump installed in an air conditioner, and a transparent drainage water drainage panel. It is composed of a drain hose.

Secondly, a service panel having a transparent peephole near the drain pump installed in the air conditioner, a dye attached to the outer frame of the drain pump, and a transparent drain for draining drain water are provided. It consists of a hose.

Thirdly, a service panel provided with a transparent peephole near the drain pump installed in the air conditioner, a solid dye placed on the drain pan, and a transparent drain hose for draining drain water are provided. It is configured.

Fourth, a service panel provided with a transparent peephole in the vicinity of the drain pump installed in the air conditioner, and an impeller rotated by the flow of drainage sent into the transparent drain hose, It consists of a transparent drain hose that drains drain water.

[0015]

According to the first aspect of the present invention, when the generated drain water is fed into the transparent drain hose through the drain pump, it is identified by the transparent peep hole of the service panel,
The operation of the drain pump can be inspected.

According to the second aspect of the present invention, the generated drain water dissolves the adhering dye attached to the outer frame of the drain pump, and the solution is fed into the transparent drain hose through the drain pump. When it is turned on, you can identify it through the transparent peephole on the service panel and check the operation of the drain pump.

According to the third aspect of the present invention, the generated drain water dissolves the solid dye placed on the drain pan, and the solution is fed into the transparent drain hose via the drain pump. At this time, the operation can be inspected by identifying it through the transparent peephole on the service panel.

According to the fourth aspect of the present invention, when the generated drain water is fed into the transparent drain hose via the drain pump, the rotation of the impeller rotating by the water flow in the transparent drain hose is You can check the operation of the drain pump by identifying it through the transparent peephole on the service panel.
