することもできる。[Function] When you finish bathing and turn on the operation button with the lid set correctly and hot water remaining in the bathtub, the second three-way valve opens to the drain side and the circulation pump starts operating. The remaining hot water will be drained from the drain pipe. When the end of drainage is detected by, for example, a pressure sensor, the first three-way valve is opened and, for example, tap water is supplied to the injection nozzle through the water supply pipe, and is injected from the injection nozzle into the bathtub, leaving some water remaining in the bathtub. Remove large debris such as hair from the drain pipe. Note that it is also possible to control such that washing away large pieces of dirt is not performed when there is no dirt.
ゴミ類の洗い流しは時間単位て終了し、次に第2三方弁

内の水を一旦加熱装置内に循環させて加熱してもよい。Once water has accumulated in the buffer, the wash liquid valve is opened and wash liquid is injected into the buffer from within the wash liquid container. Next, the first three-way valve switches to the circulation side, the heating device and the circulation pump start operating, and the heated cleaning water is injected into the bathtub from the injection nozzle. The cleaning water is heated and maintained at about 60°C, and its chemical cleaning power washes away dirt adhering to the inner walls of the bathtub. This washing is controlled on an hourly basis, and after a certain period of time,
The heating device and circulation pump are then stopped and the second three-way valve is opened to drain the dirty wash water. Note that after water is stored in the buffer, the water in the buffer may be once circulated in a heating device and heated before injecting the cleaning liquid.

浄不足が無いように注意されている。This washing may be repeated several times by first draining the water and then switching to clean water. Next, the second three-way valve is switched to the drain side, and the circulation pump drains the water to prepare for filling with water or hot water. However, when using the heating device for reheating other than cleaning the bathtub, switch the water filling section 1 and the second three-way valve to the circulation side, and turn the heating device → circulation pump → second three-way valve → first three-way valve → Reheating is performed along the route from the injection nozzle to the bathtub to the circulation port to the heating device. Next, when a heat exchanger for hot water supply is separately incorporated into the heating device, hot water is poured into the bathtub from the heat exchanger for hot water supply, and if there is a shortage or the temperature of the hot water decreases, the above-mentioned reheating is performed. Perform heating. All of the above steps are performed by signals from the controller. Note that the amount of dirt in the bathtub varies greatly depending on the number of bathers, so the cleaning time is controlled depending on the degree of dirt so that there is no waste or insufficient cleaning.
