In addition, in the case of this embodiment, the under shower spout (
(la) Corresponding to (la), one on-off valve (4a) is provided on the left side and one on the right side, and the operation part (7) is equipped with a water discharge start switch (7a) for the under shower.
There are 3 types, ``Left'' and ``Right.'' In addition, there are 3 types with different shower functions such as the water spouting start switch (7b) for the overhead shower, and the water spouting start switch (7d) for the overhead shower.
) with different water spouting positions, and two types of body shower water spouting start switches (7e) with different shower functions.

That is, the controller part (6) operates other water spouting start switches (7b) (7c) (7d) (7
e) When the water discharging start signal is input by operating (71),
Corresponding on-off valves (4b) (4c) (4d
) (4e) (4f) is opened, and the malfunction prevention means (6g) inputs a safety signal by operating the safety switch (7g). Based on this, a count is started and a predetermined time T has elapsed. When a water spouting start signal is input by operating one of the water spouting start switches (7a) of the under shower, for example, the "both" switch, both the left and right opening/closing valves (4a) (4a) are opened. When a water spouting start signal is input by operating the "left" or "right" switch, the left or right on-off valve (4a) is opened, and if the count-up occurs without inputting either of these water spouting start signals, a safety signal is sent. cancel the input.

In the case of this embodiment, when the undershower on-off valve (4a) starts to open, the opening degree of the flow rate regulating valve (5) located upstream thereof is reduced, and after a certain period of time, the valve (5) is closed. For example, after operating the safety switch (7g), "both" of the water discharge start switches (7a) of the under shower are set within a predetermined time T after the safety switch (7g) is operated. By operating the switch, the opening degree of the flow rate adjustment valve (5) is narrowed down, and at the same time both the left and right on-off valves (4a) (4a) are opened, and the instantaneous flow rate is controlled from the left and right spout ports (la) (la). To start discharging a small amount of hot water or water to the extent that it does not hit the user's body violently.

After a certain period of time has elapsed since the start of water spouting, the opening degree of the flow rate regulating valve (5) is loosened to increase the instantaneous flow rate of the hot water or water being spouted, and the opening degree of the valve (5) is adjusted to the programmed opening degree. When the instantaneous flow rate reaches the set flow rate, the opening degree of the flow rate adjustment valve (5) is maintained.

In this state, operate the water stop switch (7h) or operate the "both" switch again to close the left and right opening/closing valves (4a) (4a).
) The water discharge from (la) is stopped.

In addition, by operating either the "left" or "right" switch of the water discharging start switch (7a) of the under shower without operating the water stop switch (7h), for example, the "left" switch, the flow rate adjustment valve can be adjusted. (5) to 1/2 of the above set flow rate, and at the same time open the on-off valve (4a) on the right side.
The valve is closed to stop water spouting from the right spout (1a), and then the flow rate adjustment valve (5) is loosened to cause the instantaneous flow rate spouted from the left spout (1a) to approach the set flow rate. When the set flow rate is reached, the operation of the flow rate regulating valve (5) is stopped and the instantaneous flow rate is maintained constant thereafter.

On the other hand, in the initial state, by operating either the "left" or "right" switch of the water discharge start switch (7a) of the under shower, for example, the "right" switch, the flow rate adjustment valve (5) is throttled and both are simultaneously controlled. On-off valve (4a) (4a
), open the left and right spout ports (1a) and start discharging hot water or water with a small instantaneous flow rate to the extent that it does not hit the body too hard, and after a certain period of time, close only the left on-off valve (4a). The valve is turned to stop water spouting from the left spout (1a), and then the flow rate adjustment valve (5) is loosened so that the instantaneous flow rate of water spouted from the right spout (1a) approaches the set flow rate. The operation of the flow rate adjustment valve (5) is stopped when the set flow rate is reached.

In this state, operate the water stop switch (7h) or operate the "right" switch again to open/close the right opening/closing valve (
4a) is opened to stop water spouting from the right water spout (1a).

In addition, by operating the "left" switch without operating the water stop switch (7h), the right-hand on-off valve (4a) is closed and the water spout from the right-hand spout (1a) is stopped. At the same time, the left on-off valve (4a) is opened to start discharging water from the left water spout (1a).

Furthermore, by operating the "both" switch from this state, both the left and right on-off valves (4a) (4a) are opened,
At the same time, the flow rate adjustment valve (5) is throttled.
a) Start discharging hot water or water from (la) to the extent that it does not hit the body violently, and then loosen the flow rate adjustment valve (5) to adjust the instantaneous flow rate of water discharged from both ridge water ports (la) and (la). When the flow rate approaches the set flow rate and reaches the set flow rate, the operation of the flow rate adjustment valve (5) is stopped.

In addition, (71) in the figure is the on-off valve (4f) of the hand shower based on the program stored in advance in the controller part (6).
) Other on-off valves (4a) (4b) (4c)
(4d) This is an automatic control water spouting start switch that sequentially automatically controls the opening/closing operation of (4e), and three types are provided with different valve opening orders, respective valve opening times, etc.

Next, the operation of such a shower device will be explained.

First, in the initial state, first operate one of the under shower water discharge start switches (7a) of the operation part (7), or operate the safety switch (7g), and after a predetermined time T elapses, the under shower starts. Even if one of the water discharge start switches (7a) of the shower is operated, the on-off valves (4a) of the under shower do not open as shown in the time chart in Figure 5, and the safety switch (7g) is operated. If you then operate either one of the water discharge start switches (7a) of the under shower within the fixed time T, the left and right on-off valves (4a) (4a) or either one of the on-off valves will be activated accordingly. At the same time, only the valve (4a) is opened, and at the same time, the opening degree of the flow rate adjustment valve (5) is reduced, and hot water or water supplied from the hot water mixing faucet (3) is supplied to each spout, and each spout (1a) is opened.
), water starts spewing out to the extent that it does not hit the user's body too hard.

After a certain period of time, the opening degree of the flow rate regulating valve (5) is loosened to increase the instantaneous flow rate of hot water or water discharged, and the instantaneous flow rate of the hot water or water discharged increases to the instantaneous flow rate set in the program, and the flow rate from each spout (1a) to the shower tower body (A) is increased. Water is sprayed diagonally upward toward the lower body of the user while standing in front of the user.

If the user stands facing forward facing the shower tower (A), this upward water spout will hit the front of the waist, and if the user stands backward, it will hit the back of the waist and buttocks. It hits the thighs and calves.

In addition, if one foot is placed on the concave part (A2) on the top of the overhang part (A□) where hot water or water is spouted while standing, the sole of the foot will be touched and water will be spouted from both ridge water ports (1) (1). If you sit on a chair and place both feet on the recesses (A2) and (A2), they will hit the soles of both feet.

Furthermore, in this spouting water, operate the water stop switch (7h) of the operation part (7) or press the water spouting start switch (7h) again.
If any one of a) is operated, each open/close valve (
4a) is closed, water discharging from each spout (1a) is stopped, and the state returns to the initial state.

On the other hand, in the initial state, each water spouting start switch (7b) (7c) (7
d) (7e) If you operate (71), the corresponding on-off valve (4b) (4c) (4+])
(4e) The spout (41) opens and leads to it.
Ib) (Ic) (ld) (4e) (11)
Water starts to be spouted, and during this spouting water, the water stop switch (
7h) or press each water spouting start switch (7h) again.
b) (7c) (7d) (7e) (71
), each opening/closing valve (4b) (4c
) (4d) (4e) (4f) closes and each water outlet (lb) (lc) (Id) (Ie) (i
f) water discharging is stopped.

In the above embodiment, the under shower spout (
1a) starts water spouting only when the safety switch (7g) and water spouting start switch (7a) of the operation part (7) are operated, but the invention is not limited to this, and for example, the water spout (fb) other than the undershower (lc) (ld) (l
e) (if) also has a common safety switch (7g) and water discharge start switch (7b) (7c) (7d) (
7e) If you do not operate (71), each water spout will not start, or each water spout start switch (7g) (7b) (7c) (7d) (
7e) (It is also possible to have one film corresponding to 7D.

Further, although a pair of under-shower spouts (1a) are provided on the upper surface of the overhanging part (A) at the lower end of the shower tower body (A) diagonally upward on each left and right side, the present invention is not limited to this.
The number of a) may be 1 or 3 or more, and the number of spouts (1
The installation position in a) may be on the side wall or floor of the shower room as long as it is located below the height of the vertical center of the user's body.

In addition, each on-off valve (4a) (4b) (4c)
(4d) (4e) The opening/closing operation of (41) and the opening adjustment operation of the flow rate adjustment valve (5) (5) are controlled by the controller (6).
Although it was automatically controlled based on a program stored in advance,
The present invention is not limited to this, and the same effect can be achieved even if a relay or the like is used in addition to the program.

<Effect of the invention> Since the present invention has the above configuration, it has the following advantages.

■ Only by operating the water spouting start switch, the corresponding opening/closing valve will not open, and only when the safety switch is operated and then the water spouting start switch is operated within a predetermined time, the malfunction prevention means will open/close the corresponding opening/closing valve. Since the valve is opened, it can be operated reliably by the user's consciousness.

Therefore, compared to conventional systems in which operations are performed unconsciously and erroneous operations are likely to occur, the number of erroneous operations is significantly reduced, and the user is prevented from feeling uncomfortable due to unconscious water spouting from the shower spout. The thin water spout from the shower spout allows the user to use the shower with confidence without being surprised.
