DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a drain tank for an air conditioner.

[0002]

2. Description of the Related Art Conventionally, this type of air conditioner has been
JP-A-49298 discloses a box-shaped drain tank for collecting dew water condensed in an evaporator below a main body case, which is detachably provided. An apparatus in which a water level indicating portion is formed is disclosed.

When dew water accumulates in the drain tank, light below the water surface of the water level display portion appears transparent because light entering the water level display portion is not reflected by the uneven portions of the water level display portion. Above the water surface, the light is irregularly reflected by the irregularities and looks white. Thereby, the water level in the drain tank can be determined.

However, since the water level display portion is transparent (colorless) and whitish (white), it is not easy to recognize the water level.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner capable of easily confirming the level of dew water accumulated in a drain tank.

[0006]

Means for solving the above problems are as follows: an evaporator for cooling the air sucked from the air inlet, and an air sucked from the air inlet are provided inside a main body case having an air inlet and an air outlet. A blower that blows air from an outlet through an evaporator, a drain tank having a light-transmitting property for collecting dew water condensed in the evaporator, and a tank housing portion that houses the drain tank formed in a main body case. In the air conditioner, the drain tank facing the water level confirmation window provided in the main body case is used as a water level display section having an uneven surface,
A wall portion of the tank storage portion facing the water level display portion is brought close to the water level display portion, and a chromatic member is provided on the wall surface portion.

Thus, below the water surface, the light entering from the water level display portion enters the drain tank without being substantially reflected by the uneven portion, and the light reflected by the chromatic member is returned to the water level again. The water level indicator appears chromatic because it passes through the indicator. On the other hand, above the water surface, light that has entered from the water level display portion is almost reflected by the uneven portion, and even if it passes through the uneven portion and is reflected by the chromatic member, it is irregularly reflected into the drain tank by the uneven portion. However, the water level display board looks whitish without looking chromatic. Therefore, the water level can be determined by comparing the portion that looks chromatic and the portion that looks achromatic and whitish. In addition, by bringing the wall portion provided with the chromatic member close to the water level display section, the amount of light attenuated when light entering the drain tank from the water level display section passes through the water accumulated in the drain tank. Can be reduced, and the range in which the chromatic member can be seen from an oblique direction through the water level checking window can be increased.

In the above structure, it is desirable that the chromatic member be detachable. Thereby, it can be detached when performing cleaning or the like, and can be easily replaced.

It is desirable that the chromatic color be a color having high lightness and saturation. As a result, the water level can be determined with a color with high color saturation that is easy to recognize.

Further, the chromatic color may be a self-luminous fluorescent color. Thereby, the water level can be recognized even in a dark place.

It is desirable that the components of the air conditioner be arranged in a space on the rear surface side of the main body case generated by projecting the tank housing portion toward the front side of the main body case. Thereby, the space can be effectively used, and the entire apparatus can be made compact.
