PROBLEM TO BE SOLVED: To reduce a noise of a refrigerator at midnight or the like by providing an input means for arbitrarily inputting, and controlling to operate a compressor only for a time of operating a timer for counting a predetermined time at a rotational speed of an upper limit rotational speed or lower irrespective of an indoor temperature in a refrigerator in which the compressor and the like are controlled to be operated. SOLUTION: When a sleep switch 8 is operated and its signal is input to a controller, the controller, judges whether a 24-hour clock 10 is operated or not. In the case of operating the clock 10, it is judged that the switch 8 is already input and an operation in which upper limits of rotational speeds of a compressor 2 and an indoor cooling fan motor 3 are suppressed have been conducted. Meanwhile, in the case of operating no clock 10, it is judged that the switch 8 is operated to newly execute a sleeping operation, and the clock 10 and a timer 11 are reset and started. And, during the operation of the timer 11, suppressing operations of rotational speeds of the compressor 2, an indoor cooling fan motor 3, and a compressor and condenser cooling fan motor 4 are executed. |
