するようにされている。During the cooling operation, the condensed water generated in the indoor heat exchanger 5 drops into the indoor water tray 10 and then flows into the outdoor water tray 11. Further, during the heating operation, the outdoor heat exchanger 7 functions as an evaporator, and frost adheres to and grows on the fin surface,
For example, when the pipe temperature of the outdoor heat exchanger 7 falls below a certain value, the defrosting operation is started, and the frost is melted and stored in the outdoor water tray 11 provided below the outdoor heat exchanger 7. In particular,
During the heating operation, if the water accumulated in the outdoor water pan 11 falls below 0 ° C, it may freeze. Therefore, the outdoor water tray 11
When the water temperature inside becomes 0 ° C. or less, as shown in the flowchart of FIG. 6, the controller 15 increases the oscillation frequency of the ultrasonic vibrator 12a, uses the atomizer 12 as a heating element, and heats water. Ultrasonic transducer 12 when the water temperature becomes higher than 0 ℃
The water in the outdoor water tray 11 is prevented from freezing by stopping a. On the other hand, water collects in the outdoor water pan 11,
When the water level (h) reaches a predetermined height (for example, h 1 ), a signal from the water level detector 13 is sent to the controller 15, and the controller 15 energizes the oscillator 16 of the ultrasonic transducer 12a. The atomizer 12 is actuated and the mist is ejected from the ejection hole 12b. Of course, the ultrasonic vibrator 12a is vibrated at a frequency that allows optimum spraying. The above ejection hole 12
The mist discharged from b is scattered far by the blast air sent from the outlet of the outdoor blower 8. Also,
Even after the main body 1 is stopped, when the water level in the outdoor water tray 11 is high, the ultrasonic transducer 12a and the outdoor blower 8 are operated by the delay circuit of the control device 15 until the water level falls to a predetermined height. At the start of operation, the water level is always the prescribed water level (minimum water level). Further, the water level detector 13 automatically stops the sprayer 12 when the water runs out.

る。Effects of the Invention According to the air conditioner of the present invention, all the water generated in the indoor and outdoor heat exchangers is collected in the outdoor water tray and then discharged by the ultrasonic atomizer, so the generated water Can be discharged outdoors not only during cooling but also during the defrosting cycle during heating. Also, since the ultrasonic atomizer is arranged on the outlet side of the outdoor blower,
The fog emitted from the sprayer is forcibly discharged outdoors and does not stay as in the past, so there is no risk of misidentifying it as smoke, and it is possible to eliminate wetting near the outdoor side due to recombination of mist particles. it can. Further, since the ultrasonic atomizer is controlled based on the water level detector and the water temperature detector, by changing the oscillation frequency to the ultrasonic transducer when the water temperature becomes a predetermined temperature, for example, 0 ° C. or less, From the atomization of water, the atomizer itself can be used as a heating element, and therefore, it is possible to prevent freezing of water accumulated in the outdoor water tray even in winter. In addition, if the water level in the outdoor water pan is high after the air conditioner body is stopped,
The controller can continuously operate the sprayer to lower the water level to the predetermined water level (minimum water level). Therefore, it is possible to prevent the outdoor water pan from becoming full immediately after the start of operation.
