PROBLEM TO BE SOLVED: To reduce the possibility of contamination on a ceiling, etc., due to water leakage into a living room by operating a drain pump at high revolutions when continuous operation time of a compressor is relatively long while performing the same at low revolutions when the continuous operation time of the compressor is relatively short during a predetermined time after interruption of the compressor. SOLUTION: For a predetermined time after compressor operation interruption detection means 8 detects interruption of the compressor 7, a revolution set means 11 sets high revolutions when continuous operation time of the compressor 7 is relatively long in response to the continuous operation time of the compressor 7 detected by a counter 9 while setting low revolutions when the continuous operation time of the compressor 7 is relatively short, and outputs them to pump driving means 12. The pump driving means 12 operates a drain pump 3 with the number of revolutions outputted from the revolution set means 11. Hereby, there is reduced the possibility of a ceiling and a wall surface, etc., being contaminated owing to water leakage into a living room. |
