[0012] Next, the mechanism of bath water purification and heat retention will be explained. First, the bath water sucked in from the suction port 5 is filtered by a filter of the first purification device 6 to remove dust such as hair. Next, fat and the like are removed by a filter stone in a second purifying device 8 via a circulation device 7, and the bath water is returned to the bathtub 3 through a discharge port 10 and this circulation is repeated to keep the bath water always clean. For this purification effect, the circulation device 7 is always operated by the bathing time control means 35 during the bathing time determined by the bathing time setting device 22. On the other hand, outside the time set by the bathing time setting device 22, the circulation device 7 is forcibly operated for 10 minutes every hour by the bathing outtime control means 36.

On the other hand, regarding heat retention, if the water temperature detected by the temperature detection device 11 is lower than the set temperature, the heating device 9 heats the water. At this time, during the bath time set by the bath time setting device 22, the bath water is always kept at the set temperature by the bath time control means 35 and the circulation device 7 and heating device 9. on the other hand,
Outside the set time of the bathing time setting device 22, the bathing time overtime control means 36 detects the water temperature 10 minutes after every hour and sets it to 35°C.
In the following cases, the bath water is heated to 35° C. by the circulation device 7 and heating device 9 only once. In the case of Figure 2, the water temperature is always kept at about 41°C from 6pm to 9pm, and around 35°C at other times.

Next, the function of the absence switch 27 is determined by pressing the switch 27 before going out for several days.
The ED 28 lights up, and as shown in FIG. 3, the switching means 34 of the control device 33 causes the bathing time outside control means 36 to keep the water temperature around 35° C. regardless of the bathing time set by the bathing time setting device 22, thereby saving energy. The aim is to This switch is released by pressing it again when returning home, and at the same time the operation display LED 28 turns off, the temperature is maintained according to the bath time set by the bath time setting device 22.

Next, the function of the bathing switch 29 is that when it is pressed when suddenly taking a bath outside the set bathing time, the display LED 30 lights up and at the same time the circulation device 7 and heating device 9 are activated until the water temperature reaches the set temperature. It is heated.

As described above, in this embodiment, during the bathing time set by the bathing time setting device 22, the bath water is always kept clean and at the set temperature, and outside the time set by the bathing time setting device 22, the bath water is kept clean for 10 minutes every hour. The circulation device 7 is forcibly operated, and the bath water temperature is detected 10 minutes after every hour, and if it is below 35°C, the bath water is heated only once by the circulation device 7 and the heating device 9 to 35°C. By doing so, the power consumption of the circulation device 7 and the heating device 9 is suppressed as much as possible to save energy, and even in the case of sudden bathing, it is possible to take a bath in a relatively short time.

Furthermore, if the absence switch 27 is pressed before going out for several days, the bathing time overtime control 36 is always performed regardless of the time set by the bathing time setting device 22, so that even if the bathing time is within the set time, However, the bath water is kept warm at around 35° C. by the purification device and the circulation device without boiling the bath using the heating device, and at the same time keeps the bath water clean and saves energy.
