A high temperature adjustment valve 11 is connected thereto.

Reference numeral 12 denotes a cold water pipe, and the cold water temperature _t2 is, for example,
In order to set the temperature to 20°C, the water is communicated with the hot water storage tank 7 via a third switching valve 13 operated by the timer and connected to the room temperature water channel 9 via a fourth switching valve 14 operated in synchronization with the third switching valve 13. A low temperature regulating valve 15 is connected.

16 is a mixing valve in which hot water pipe 6 and cold water pipe 12 are connected in parallel to alternately supply hot water and cold water to each injection pipe 2 via water supply pipe 3, and the capacity can be increased or decreased. Adjustment screw 17 to
A movable plate 17 is provided therein, and the movable plate 17 is movable and adjusted by the timer, and excites (demagnetizes) the first and second switching valves 8 and 10 according to the command from the timer, and also controls the third and fourth switching valves 13 and 13. When the hot water pipe 6 is opened and the cold water pipe 12 is closed by demagnetizing (energizing) the hot water pipe 14, the hot water set at the water temperature _t1 by the high temperature adjustment valve 11 is unilaterally supplied into the mixing tank 16. While hot water is continuously injected at high water pressure from the nozzle group 2a of each injection pipe 2, after the time set by the timer has elapsed, each switching valve 8, 1
0, 13, and 14 to close the hot water pipe 6 and open the cold water pipe 12, the cold water set at the water temperature _t2 by the low temperature adjustment valve 15 is unilaterally supplied into the mixing tank 16. Cold water is continuously injected at high water pressure from the nozzle group 2a of each injection pipe 2, and the alternating injection of hot water and cold water is repeated according to a command from a timer. When switching from hot water to cold water, the cold water pipe 12 is connected to the mixing tank 16.
The cold water that sequentially flows into the mixing tank 16
The temperature t of the water supplied to each injection pipe 2 gradually decreases with the passage of time m as shown in FIG. 4 until the mixing tank 16 is filled with cold water. The temperature changes stepwise over time and changes to the set cold water temperature t ₂ , and the water is switched to cold water.
When switching from cold water to hot water, each injection pipe 2
The water temperature t supplied to the water changes steplessly over time and changes to the set hot water temperature _t1 , and the water is switched to hot water. Note that if the movable plate 17 in the mixing tank 16 is moved to increase or decrease the capacity of the mixing tank 16,
The switching time and water temperature gradient during switching can be adjusted.

18 is a temperature sensor installed in the middle of the water supply pipe 3, which detects the abnormal temperature when water with an abnormal temperature flows through the water supply pipe 3, and activates a solenoid valve 19 installed in the middle of the water supply pipe 3. Water supply pipe 3
can be closed. In addition, the solenoid valve 19 closes the door 1 of the shower room 1 while the timer is operating.
When the door switch 20 detects the opening of the door 1a, it operates to close the water supply pipe 3, and when the door switch 20 detects the opening and closing of the door 1a, it returns and opens the water supply pipe 3, interlocking with the door 1a. The water discharge from the injection pipe 2 can be controlled by

Note that 25 and 25 are warm air ducts connected to the upper and lower parts of the shower chamber 1 to dry the body after a shower, and a blower (not shown) is activated by a switching signal from the timer after the hot and cold water is finished being sprayed. Warm air is blown into the shower room 1.

Next, the operation and effects of the embodiment having the above configuration will be explained.

In this example, each injection pipe 2 installed in the shower chamber 1 is connected to alternately supply hot water and cold water to each injection pipe 2 in order to spray shower from the surrounding area toward the body. The mixing tank 16 has a hot water pipe 6 connected to a high temperature adjustment valve ₁₁ for setting the hot water temperature t1, and a hot water pipe 6 connected to the high temperature adjustment valve 11 for setting the hot water temperature t1.
