行し循環ポンプを停止させ、処理１に戻る。In the freeze prevention operation, the operation shown in the flow chart of FIG. 2 is performed. That is, in the process 1, the temperature of the bath water 26 is checked by the bath temperature detector 28, and the process 1 is repeated when the temperature is high without freezing, and the process 2 is performed when the temperature is low with freezing. In process 2, the circulation pump 27 is operated and the process proceeds to process 3. In process 3, the bath water switch 32 is used to confirm water flow, and when it is confirmed that there is water flow, the process moves to process 4 and the temperature of the bath water 26 is checked by the bath temperature detector 28 to freeze the temperature of the bath water 26. In the case of a low temperature at which there is a risk of, the operation of the circulation pump is continued until the temperature at which there is no fear of freezing, and then the process proceeds to process 5, the circulation pump is stopped, and the process returns to process 1.

２５の凍結を防止するものである。When it is confirmed that there is no water flow in the process 3, the process shifts to the process 6, the circulation pump is stopped, and the process shifts to the process 7. In process 7, the outside air temperature T is detected by the outside air temperature detector 33, the process proceeds to process 8, and the stop time t1 of the circulation pump 27 according to the outside air temperature T detected in process 7
After the stop time t1 has elapsed, the process proceeds to the process 9 and the circulation pump 27 is operated. In process 10, the circulation pump 27 is operated until the time t2 in which the water in the circulation pump 27 is sufficiently heated by the heat generation of the circulation pump elapses, and the process returns to process 3. By performing the intermittent operation in which the above operation is repeated, the circulation circuit 25 is prevented from freezing.

In the antifreezing operation of the circulation pump 27 when there is no 6, the stop time t1 is shortened when the outside air temperature T detected by the outside air temperature detector 33 is very low, and the stop time t1 is lengthened when it is not too low. As a result, the circulation pump 27 is operated only for a minimum time without freezing, so that the number of times of operation of the circulation pump 27 is reduced, power consumption can be reduced by the operation of the circulation pump 27, and the operation of the circulation pump 27 can be reduced. It is possible to minimize the time when an unpleasant driving sound is generated due to annoying noise caused by.

That is, when the outside air temperature T is not too low, the circulation circuit 25 is less likely to freeze, so that the operating time t2 of the circulation pump 27 can be shortened. As a result, when the outside air temperature T is not too low, the operation time of the circulation pump 27 in the antifreezing operation can be shortened and the operation interval can be lengthened, so that the operation time of the circulation pump 27 is further reduced and It is possible to reduce power consumption and driving noise due to driving.
