I am trying to be. Thus, the shortage of steam near the neck of the bather 4 is compensated for, the temperature-sensitive back portion is avoided, the shoulder and neck streaks are efficiently heated, and the temperature near the opening 55 of the lid 6 is prevented from lowering. At the same time, blood circulation to the head can be promoted. Also,
Since the fragrance case 26 is provided at the end of the communication pipe 25, aroma terraby using an aroma (perfume) material or the like is possible.

Further, in the bathing state, the legs of the bather 4 are placed on the leg rest members 31 and are kept at a position higher than the heart, so that the bathing is performed in a lying state. This can promote blood circulation in the legs,
Since the leg placing member 31 is movable, so-called tail fin movement can be performed during bathing.

The temperature of the steam from the steam generator 16 is set to a predetermined optimum temperature.
The plate-shaped heating element 20 is turned ON / OFF according to this optimum temperature.
Although controlled, the optimal temperature of the bather 4 varies depending on the person, and the preset optimum temperature may be too high for the bather 4 in some cases. Therefore, in this case, the plate heating element 20 is turned off.
Even if 0 is turned off, the temperature in the bathtub space 7 does not immediately drop.

Therefore, in such a case, the cool air blower 29 shown in FIG. 1 is activated, and cool air is positively sent into the central groove 13. Thus, the temperature in the bathtub space 7 can be quickly lowered and adjusted to the optimum sensible temperature of the bather 4.

When the bathing with steam is completed in this way, the motor 22 is stopped and the plate-shaped heating element 20 is turned off, and at the same time, the hot water shower by the shower device 38 is started. Then, the pack material and sweat applied to the body of the bather 4 are washed away by the hot water shower.

This hot water shower is, for example,
Hot water shower from 6 for 16 seconds, right side nozzle 3
5 hot water shower from left side nozzle 3 for 16 seconds
Hot water shower from 5 to 3 with 16 second rotation
Repeated ~ 4 times. Then, by changing the jetting direction of the hot water shower, the whole body of the bather 4 and the perspiration can be completely washed away.

In the final stage of the hot water shower, a chemical solution such as a lotion or a scented water is injected into the shower water by activating the injection pump 50 shown in FIG. 12, so that the whole-body beautiful skin conditioning can be performed.

Since the steam from the steam generator 16 is supplied into the bathtub space 7 through the steam passage inside the bathtub section 5, the steam can be uniformly spread over the entire body of the bather 4. The bathing effect can be improved.

The hot water shower is operated by the nozzles 35 on both sides.
And since it is sequentially sprayed from the upper nozzle 36, the pack material and sweat can be completely washed away.

Since the head of the bather 4 is exposed outside the cover 6 during bathing, the scalp care and hair washing can be performed using the hair washing device 58 during bathing. The solution after the completion of the hair washing is collected in the pit 10 and discharged from the drain port 12.
