を停止する処理をする。The control operation of the control circuit 8 is as shown in the flow chart of FIG. That is, when the cooling operation of the air conditioner is started, it is determined in step # 1 whether the lower water level detection sensor 6 has an output. If there is no output from the lower water level detection sensor 6, the drain water level is normal, and processing is continued in step # 2. If there is an output from the lower water level detection sensor 6, then the drain water level is abnormal in step # 3. An abnormality warning is displayed on the display means 10, processing for continuing the operation is performed, and the process proceeds to step # 4. In step # 4, it is determined whether or not the upper water level detection sensor 7 has an output. If there is no output in the upper water level detection sensor 7, the abnormality warning is continued and the operation is continued in step # 5. If there is an output in the upper water level detection sensor 7, the drain water level is abnormal in step # 6. Assuming that there is, an abnormality warning is displayed on the display means 10, and processing for stopping the cooling operation is performed.

けではないので、詰まったりすることは殆どない。If the lower water level detection sensor 6 has an output,
The drainage pipe 5 connected to the first drainage port 3 is defectively drained or cannot be drained due to slime produced by microorganisms in dust or water. Therefore, an abnormal warning is displayed and the air conditioner is not operated. continue. The user who recognizes the abnormality warning contacts the maintenance company and requests that the abnormality be resolved. However, there may be cases where the maintenance company does not respond immediately, but during this time there is no inconvenience that the air conditioning cannot be done.
When time passes after the abnormal warning and the condensed water accumulates in the water tray 2 and reaches the water level of the second drain port 4, the condensed water is drained from the second drain port 4 through the drain pipe 5.
Since the second drain port 4 and the drain pipe 5 do not always function, they are hardly clogged.

い。However, the first and second drain ports 3 and 4 or the drain pipe 5 may be clogged together. In such a case, the operation is stopped if the condensed water reaches the water level of the upper water level detection sensor 7 while continuing the abnormal warning, and the overflow from the water pan 2 is prevented in advance. As described above, in the present air conditioner, even if the first drain port 3 or the drain pipe 5 has poor drainage, the cooling operation can be continued while the drainage failure is eliminated, which is convenient. There is a grace period until the drainage failure is resolved. The first and second drain ports 3 and 4 are
The drain treatment device can be made smaller by providing it on the bottom surface of the water tray 2, but there is no problem in function even if it is provided on the side surface.
