The inside of the main body 1 is partitioned by a partition wall 12 into a heat source side air chamber 13 and a use side air chamber 14, and inside the heat source side air chamber 13, a condenser 4, a condenser fan 5, a compressor 6, a drain tank 10, etc. An evaporator 2, an evaporator fan 3, a drain pan 8 and the like are provided in the use side air chamber 14.

During the cold air operation of the air conditioner, the compressor 6 is driven, and the condenser fan 5 and the evaporator fan 3 are driven by the fan drive motor 7.

Then, the refrigerant gas discharged from the compressor 6 flows into the condenser 4 and is condensed and liquefied by exchanging heat with air there, and then adiabatically expanded by being throttled by a throttling mechanism (not shown), and then the evaporator. It flows into 2 and evaporates and vaporizes by exchanging heat with air here, and in this state, it circulates again to the compressor 6. On the other hand, the indoor air is sucked into the heat source side air chamber 13 through the suction ports 15 provided on both sides of the lower portion of the main body 1, flows through the condenser 4 to raise the temperature, and then is urged by the condenser fan 5. Then, it is blown out from the exhaust port 16 provided on the rear surface of the main body 1. At the same time, the indoor air
Is sucked into the use-side air chamber 14 from the suction port 17 provided at one side of the upper part, cooled by passing through the evaporator 2, and then urged by the evaporator fan 3 to the front surface of the main body 1. It is blown out from the conditioned air outlet 18 provided.

Moisture contained in the air cooled by the evaporator 2 is condensed and dropped on the drain pan 8, and is stored in the drain tank 10 via the drain hose 9.

During the dehumidifying operation of the air conditioner, the damper 20 that opens and closes the communication hole 19 provided in the partition wall 12 is opened, and a part of the air heated through the condenser 4 is cooled in the air cooled through the evaporator 2. The mixed air is blown into the room from the conditioned air outlet 18 as dehumidified air.

The upper main body 1a, which constitutes the upper part of the main body 1, is formed by molding a synthetic resin, and a flat operation panel 21 is attached to the upper part, that is, the three-dimensional curved surface part in a tilted state.

The mounting structure of this operation panel 21 is shown in FIG.
