あるかを判別している。When the surroundings of the air detection thermistor 14 are water (warm water), since the heat radiation after heating is relatively large, the temperature difference before and after heating is small. When the surroundings are air, the temperature difference before and after heating is large because heat radiation after heating is relatively small. Based on the magnitude of this temperature difference, it is determined whether the surroundings are water (hot water) or air.

し、直ちに元電磁弁9で温水の供給を停止する。If it is determined in step S4 that it is dangerous,
No cleaning water is supplied to the human body. This determination prevents hot water from being supplied from the cleaning nozzle 17 to the human body part, thereby ensuring safety in the event of an emergency. Note that even during use, the temperature of the hot water is reduced by 50% due to the post-boiling of the heat exchanger 12 or the failure of the temperature control system of the heat exchanger 12.
When the temperature exceeds ° C, the hot water thermistor 16 detects this and immediately stops the supply of the hot water by the original solenoid valve 9.

また故障の原因となることを防止している。Here, the actuation of the air pump 21 first is a measure for preventing water from flowing backward even if the check mechanism of the air pump 21 itself fails. Due to this effect, water or hot water flows back into the air pump at the start of use, resulting in reduced or deteriorated performance.
Also, it is prevented from causing a failure.

The power consumption can be significantly reduced. At the start of cleaning of the human body by the setting of the cleaning setting means, the water supply control means is operated after the air mixing means is operated.Therefore, the cleaning liquid flows back to the air mixing means at the start of use, resulting in performance degradation or deterioration. This can prevent a failure from occurring.

手段の立ち上がりの促進が確実に図れる。After the heating means is stopped by the air delay control means, the delay time is managed to stop the air mixing means, so that the air is accumulated in the inside of the heating means, the hot water pipe, and the discharge means due to boiling after the stop. High-temperature cleaning liquid can be discharged, preventing hot water from being supplied to the human body part when reused for a relatively short time, and cold cleaning liquid to the human body part when reused after a long period of non-use. Thus, it is possible to reliably prevent the supply of water and promote the rising of the heating means.
