AIR CONDITIONING DEVICE
FIG4 is a view for showing a cooling unit, the humidification unit and a discharged-water storage unit of the air conditioner
Next, the discharged-water storage unit 40 is described. The discharged-water storage unit 40 is disposed for storing water discharged from the cooling unit 14 and the water discharged from the humidification unit 20. In the example shown in FIG4, the discharged-water storage unit 40 is structured as the drain pan 41 disposed below the cooling unit 14. The exhaust pipe (first exhaust pipe) 46 for discharging water stored in the discharged-water storage unit 40 is connected to the discharged-water storage unit 40 (drain pan 41). In the illustrated example, the air conditioner 10 has a pump P for discharging water stored in the discharged-water storage unit 40. The exhaust pipe 46 is connected to the pump P at an end opposed to the end connected to the discharged-water storage unit 40. In the illustrated example, the exhaust pipe (second exhaust pipe) 34 for discharging water in the storage tank 22 of the humidification unit 20 is connected to the exhaust pipe 46 at a connection 48 positioned at an intermediate portion of the exhaust pipe 46. Thus, the exhaust pipe 46 has the first part 461 that extends from the discharged-water storage unit 40 to the connection 48, and a second part 462 that extends from the connection 48 to the pump P. As described above, water droplets adhering to the cooling unit 14 fall down into the discharged-water storage unit 40 disposed below the cooling unit 14 so as to be stored in the discharged-water storage unit 40. In addition, water discharged from the storage tank 22 of the humidification unit 20 flows into the discharged-water storage unit 40 so as to be stored therein through the exhaust pipe 34 and the exhaust pipe 46 (first part 461) or through the overflow pipe 38, the exhaust pipe 34 and the exhaust pipe 46 (first part 461). In the example shown in FIG4, liquid level detectors 44, 45 that detect water levels in the discharged-water storage unit 40 are disposed in the discharged-water storage unit 40. Particularly in the illustrated example, in the discharged-water storage unit 40, there are a lower water level detector 44 disposed relatively below, and a higher water level detector 45 disposed relatively above. Float switches may be used as the water level detectors 44, 45, for example.
