A packet filter 3 is interposed in the reflux pipe 34 to the reflux pipe 34 .

The configuration of the alternate hot and cold water injection system from the rear shower nozzle 40 will be explained based on FIG.

In the figure, a branch pipe 47 branches off from the hot water supply pipe 44 and is connected to the cold water supply pipe 46 via a valve device 52 that is opened and closed by a solenoid 50. The cold water supply pipe 46 is provided with a valve f53 that is opened and closed by a solenoid 51, and has branch pipes 48.49 connected to the hot water supply pipes 42.44. In addition, ball valves 22D are provided between the communication portions of the branch pipes 47 and 48 of the hot water supply pipe 44 and in the branch pipes 49, respectively.
.

22C is provided. Further, a ball valve 22g is provided on the downstream side of the cold water supply pipe connection portion of the pipe 29.

Next, the operation will be explained.

■ By operating the mixing valve 1.1', the circulation tank 4
Hot water is supplied to the cleaning tank 25, and cold water is supplied to the cleaning tank 25.

■ Circulation switch in control circuit 38 (not shown)
When turned on, the hot water in the circulation tank 4 is pumped up by the centrifugal pump 8, passes through the line filter 11, and is injected at once from the plurality of shower nozzles 19, 19'.

At this time, the control circuit 38 controls the electric ball valve 12, so that the hot water injection force is initially weak (see A in Figure 3) and becomes stronger after a certain period of time (see B in Figure 3).
(see).

By operating the electric ball valve 12, when lowering the water pressure, the water flows through the path a without the electric pole valve 12, and when increasing the water pressure, the water flows through the path where the electric ball valve 12 is present.

■ Ball valves 22A and 22D for alternately spraying hot and cold water from the rear shower nozzle 40.

22E is closed by hand, ball valves 22B and 22C are opened by hand, and an electric valve switch for circulation (not shown) is used.
and close the electric drain valve switch (not shown), and a timer (not shown) in the control circuit 38 determines the hot and cold water injection time (i.e., valve device 52.5).
3 alternate opening/closing times). For example, the hot water jetting time from the rear shower nozzle 40 is set to be longer than the cold water jetting time. When the settings are completed, a manual switch (not shown) is turned on, and the hot water in the circulation tank 4 and the cold water in the cleaning tank 25 are pumped up by the centrifugal pumps 8.8'. The valve devices 52, 53 are alternately opened and closed by signals from the control circuit 38, respectively. Then, when the valve device 52 opens and the valve device 53 closes, the hot water in the circulation tank 4 flows from the piping 28 to the hot water supply pipe 44.
- branch pipe 41 - valve device 52 - branch pipe 48, 49 and is ejected from the rear shower nozzle 40. Further, when the valve device 52 is closed and the valve device 53 is opened, the cold water in the cleaning tank 25 is transferred from the pipe 29 to the cold water supply pipe 46 to the valve device 53 to the branch pipe 48.49.
The water is then sprayed from the rear shower nozzle 40. In addition,
Only hot water is spouted from the front shower nozzle 19, the ceiling shower nozzle +9', and the lower shower nozzle 20.

(2) The water collected from the drain port 27 of the shower pit P passes through the packet type filter 3 and returns to the circulation 1M tank 4 for circulation by the operation of the electric ball valve 8.

■ Cleaning switch in control circuit 38 (not shown)
When turned on, the water in the cleaning tank 25 is pumped up by the SS pump 8', and the water is pumped up to the hand shower nozzle 2.
After being sprayed from 0', drain port 2 of shower pit P
7 through a drain pipe 35.

In this case, by operating the three-way electric ball valve 17 and the chatter valve 21, it is possible to switch between spraying from the ceiling shower nozzle 19' and spraying from the hand shower nozzle 20'.

Circulation tank 4. Drainage from the communication drain pipes 36 and 37 led out from the cleaning tank 25 is carried out by an electric ball valve 18.
'Controlled by '.

According to the shower device configured in this way, it is possible to bathe in hot water from the front through the front shower nozzle 19, and to alternately bathe in hot water and cold water (the spouting time of hot water is longer than that of cold water) from the rear through the rear shower nozzle 40. can.

As a result, hot and cold bathing, which could not be expected with conventional showers, becomes possible, and it is possible to promote blood circulation and metabolism in the skin more than in the case of thermal stimulation.

Moreover, since hot water is sprayed from the front by the front shower nozzle 19, there is less cooling sensation and stimulation to the heart, ensuring safety in use.

Furthermore, by setting the timer, you can freely select the hot and cold water injection times, allowing you to bathe in a way that suits your personal preferences.

Furthermore, by circulating the hot water of the shower, water can be continuously spouted from the plurality of front shower nozzles 19°, ceiling shower nozzle 19', lower shower nozzle 20, and rear shower nozzle 40 with a small amount of water.

In addition, since a hand shower nozzle 20' for washing is provided, the whole body can be washed at the end, and there are no hygiene problems.

Furthermore, since the electric ball valve 12 controls the water pressure so that it is initially low and gradually increases, the water temperature and water pressure have little sudden effect on the body, and safety is high.

Note that a valve device including a three-way valve may be provided between the rear sower nozzle and the hot water supply pipe and the cold water supply pipe to switch hot and cold water.

Further, as the valve device, a valve that is opened and closed by hydraulic pressure or pneumatic pressure may be used.

〔Effect of the invention〕

According to the shower device of the present invention, the following effects can be obtained.

Since hot water is bathed from the front and hot water and cold water are alternately bathed from the back, it is possible to take hot and cold baths, which promotes blood circulation in the skin and metabolism.

Moreover, since the warm water is bathed from the front, there is less stimulation of the heart (and safety of use is ensured).
