Hereinafter, the conventional air conditioner will be described with reference to the drawings. FIG. 6 is a central longitudinal sectional view of a conventional air conditioner.

In FIG. 6, reference numeral 1 denotes an air conditioner main body, which has an air blower 2 and a heat exchanger 3 inside, and a suction port 4 and a blow-out port 5 at both side ends, which are arranged at the lower surface of the central portion. It is connected by ventilation path 6.

On the other hand, a drain pan 7 is provided below the heat exchanger 3, a drain pump 8 is provided in a water collecting portion 7 a of the drain pan 7, a drain hose 9 connected to the drain pump 8 and a main drain port 10 located above the drain hose 9. At the deepest part 7b of the water collecting part 7a, a service drain port 11 and a rubber sealing plug 12 inserted and sealed in the service drain port 11 are provided.

The operation of the air conditioner configured as above will be described below. First, the drain water condensed by the heat exchanger 3 is collected by the drain pan 7, absorbed by the drain pump 8 when reaching a predetermined water level, passes through the drain hose 9 and is discharged from the main drain port 10. .

On the other hand, since the drain water that is not absorbed by the drain pump 8 remains in the deepest portion 7b, the rubber-like sealing plug 12 is pulled out and drained from the service drain port 11 when the season is off.

[0009]

[Problems to be solved by the device]

 However, in the above-described conventional configuration, when the user does not discharge the residual water from the service drain port 11 every season off, the residual water in the drain pan 7 is contaminated and rotted due to the influence of dust and mold bacteria in the air. When the drain water starts to flow again in the next season, the solid dry matter may become clogged at the water intake port of the drain pump 8 or abnormal mold growth may occur. The drain pan 7 is easily contaminated, and once this happens, the air conditioner must be disassembled to clean the drain pan 7.

An object of the present invention is to solve the above conventional problems and to provide a highly reliable drainage structure and a sanitary air conditioner.
