Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain tank water level confirmation device for a local air conditioner installed in a factory.

[0002]

2. Description of the Related Art In recent years, there has been a growing demand for a drain tank water level confirmation device for a local air conditioner of this type, although the drainage time of the drain water collected in the drain tank can be easily confirmed with the spread of the local air conditioner.

Conventionally, a drain tank water level confirmation device of this type of local cooling machine generally has a structure as shown in FIG. The configuration will be described below with reference to FIG.

As shown in the figure, the body 101 of the local air conditioner
A drain tank 102 is provided in the lower portion, and a water level window 103 for confirming the water level of the drain tank 102 is provided on the lower side of the body 101.
Was provided.

In the above structure, the main body 10 is operated during the cooling operation.
The drain water condensed and discharged in the drain tank 102
Will be collected. The user checked the amount of drain water in the drain tank 102 made of a translucent resin by looking through the water level window 103, and if the water was full, the drain tank 102 was transported and the drain water was drained.

[0006]

In such a conventional drain tank water level confirmation device for a local air conditioner, the drain water level in the drain tank 102 is passed through the water level window 103 through the drain tank 102 made of a translucent resin. Since it was visually confirmed, it was difficult for the user to accurately check the water level with colorless and transparent water in the drain tank 102 and the translucent drain tank 102, and the collected drain water exceeded the full state of the drain tank 102. There was a problem of getting the floor around the local air conditioner wet.

The present invention is intended to solve the above problems, and a user can surely judge the water level in the drain tank with his / her eyes, and the drain tank water level confirmation device for a local air conditioner does not mistake the drain time of the collected drain water. The first purpose is to provide.

A second object is to prevent the water level in the drain tank from being mistaken even when installed in a relatively dark work place.

[0009]

In order to achieve the above first object, the drain tank water level confirmation apparatus for a local air conditioner of the present invention has a first means, which is a drain tank made of a translucent resin, and this drain tank. A visual auxiliary means provided in the drain tank so that the projection surface corresponds to the inside of the side wall for visually observing the water level of the water level of the drain water accumulated in the drain tank. The configuration will be confirmed by.

Further, in order to achieve the second object, the second means has a construction in which the projection surface of the visual aid means is provided with a fluorescent color.

[0011]

According to the present invention, when the drain water is collected in the drain tank and the level of the drain water rises by the configuration of the above-mentioned first means, when the drain water is not initially accumulated, the visual aid means is provided. The projection surface reflected light and had brilliance and brightness, but due to the contact of drain water with the projection surface,
The brightness of that part becomes dull and dark, and the light level can be confirmed on the projection surface between the part that is not submerged in drain water and the part that is submerged in water.

Further, with the configuration of the second means, the projection surface shines even when weak light is received, and the boundary between bright and dark can be discriminated, so that the water level can be confirmed even in a weak illumination place.

【Example】

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIG.

As shown in the figure, a drain tank 1 for collecting drain water condensed in a local air conditioner during cooling operation is formed of a semitransparent resin, and a side wall 1a for visually observing the water level of the collected drain water is provided. The full line 2 is provided, and the visual aid 3 is provided inside the side wall 1a so that the projection surface 3a corresponds to it.

Then, the projection surface 3a of the visual aid 3 is a thin plate made of metal such as stainless steel or aluminum that reflects light.

With the above structure, when the drain water is collected in the drain tank 1 and the drain water level rises, the projection surface 3a of the visual aid 3 reflects light when the drain water is not initially stored. It has a brilliance and brightness,
As the projection surface 3a is submerged in the drain water, the submerged projection surface 3a becomes darker than the non-submerged projection surface 3a, and when viewed from the side wall 1a side of the drain tank 1, the projection surface 3
The part of a that is not submerged in water and the part that is submerged in water are divided into bright and dark areas, and the position that becomes the boundary line represents the water level. The position of the boundary line that represents this water level is the full water line 2 applied to the drain tank 1.
The drain water in the drain tank 1 should be drained when approaching.

As described above, according to the drain tank water level confirmation apparatus for the local air conditioner of the first embodiment of the present invention, as the projection surface 3a of the visual aid 3 is submerged, the submerged portion becomes darker and submerged. The light and dark areas can be easily seen and the water level can be confirmed accurately, the drainage time is correct, and it is possible to prevent the drain water from becoming full and wetting the floor and the like.

In the first embodiment, the projection surface 3a of the visual aid 3 is formed of a thin plate of stainless steel or aluminum, but the projection surface 3a of the visual aid 3 is described.
Is not limited in its material and shape as long as it receives light and reflects it, and it suffices as long as it is possible to visually distinguish lightness and darkness between the part not submerged in drain water and the part submerged in drain water. There is no end.

(Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIG.

Regarding the same parts as in the first embodiment,
The same reference numerals are given and detailed description is omitted.

As shown in the figure, the projection surface 3b of the visual aid 3 is provided with a fluorescent color that reflects even weak light.

With the above structure, the side wall 1 of the drain tank 1
When viewed from the side a, the fluorescent color applied to the projection surface 3b of the visual aid 3 shines upon receiving weak light, so that the fluorescent color makes the contrast clear and the water level can be confirmed by light and dark.

As described above, according to the drain tank water level confirmation device for the local air conditioner of the second embodiment of the present invention, it is possible to easily visually confirm the water level in the drain tank in a place where the illumination is weak.

[0024]

As is apparent from the above embodiments, according to the present invention, a visual aid is provided so that the projection surface corresponds to the inside of the side wall for observing the water level of the drain tank. The drain tank water level confirmation device for the local air conditioner that allows the user to reliably judge the water level in the drain tank with eyes and prevent the collected drain water from leaking to the floor due to full water. Can be provided.

Further, since the projection surface of the visual aid is colored with fluorescent color, it is possible to make visual confirmation in a place where the illumination is weak.
