After the user enters the compartment, the user locks the door, disabling coin insertion and allowing the user to use the shower. Also, for example,
Some models, such as No. 128881, are equipped with a control device that allows the shower to be used by inserting a coin to open and close the reshower valve.

(Problem to be Solved by the Invention) However, according to the first conventional technology, there is no management control over the use of the shower itself, leading to waste due to leaving the shower running and water overflowing due to this. This causes inconvenience. The second conventional technology manages and controls this hot water supply itself based on time, and there is no problem like the first conventional technology. However, the second conventional technology allows shower use only for a certain period of time by inserting a coin. This disclosure discloses a control device for controlling the shower system, but does not disclose any relationship with other devices such as setting the shower temperature, displaying the usable time, and cleaning management after using the shower. When installing it in a vehicle, due to the limited space and vibrations, it is necessary to fully consider the safety of the user and to systemize it from the point of view of maintenance management. Technology did not consider such systemization.

Therefore, an object of the present invention is to provide a shower system in which various functions are systematized with due consideration to user safety and maintenance management.

(Means and effects for solving the problem) In order to achieve this object, the present invention provides a shower head (21) that supplies hot water to the compartment (1) for the shower user to enter, and adjusts the temperature of the hot water supply. a shower switch (23) that prompts you to start or stop hot water supply.

Figure 4 shows the water channel system of a vehicle shower system having the compartment (1) as described above. Hot water is supplied to the shower head (21) by a water storage tank and a hot water tank (both water (not shown) and hot water respectively through two inlaid pipes (31
), (32) to the mixing faucet (22). This mixing faucet (22) is a well-known type, and for example, a predetermined amount of water is supplied so that a predetermined hot water temperature specified by a dial can be obtained. and the amount of hot water is mixed and adjusted continuously. Detection of the hot water supply temperature is performed, for example, by a thermostat, and control of the amount of water and mixing of the amount of hot water, that is, control of the valve opening degree, is executed according to a predetermined program using a microcomputer or the like. Hot water heated to a desired temperature with such a mixing faucet (22) is supplied to an electromagnetic water stop valve (34) via a constant flow valve (33). The electromagnetic water shutoff valve (34) is connected to the shower switch (2) on the shower operation panel (13).

Install it on the wall on the aisle side of compartment (1).
The calculation means (40a) of the control unit (40) determines whether the input conditions of the door lock (41), usage card acceptance (42), hot water tank temperature (43), and water storage tank water level (44) are appropriate. and sends a predetermined command signal, and achieves the following five functions: first, when the temperature (43) of hot water in the hot water storage tank is lower than a predetermined temperature; When the tank water level (44) is lower than a predetermined water level, a lamp (46) is turned on to indicate that a shower is being prepared. In this case, the door (2) may be forcibly locked.Secondly, the shower user may lock the compartment (1)
Due to the condition of the door lock (41) that entered the room and locked the door (2), the lamp indicating that it is in use (
47) lights up. Third, if the shower user enters the compartment (1) and locks the door (2) (
41), a timer is started, and if no card is accepted within a certain period of time (42), an alarm is generated to monitor wasteful use. This situation may occur if the person enters the compartment and stays for a long time without using the shower. Fourth, even if the door lock (41) and card acceptance (42) conditions occur, if the shower switches (23) and (24) are not operated for a considerable period of time,
Alternatively, if the door lock condition (41) is not released even after a considerable period of time has elapsed, it is determined that there is something wrong with the user, and the emergency lamp (4 days) is flashed. Fifth, input conditions (41
to 44) are all appropriate using the calculation means (40
b).

The calculation means (40b) of the control unit (40) has the following functions. First, upon receiving a signal from the calculation means (40a) indicating that the input conditions (41 to 40 are all appropriate),
The shower switches (23) and (24) can be operated. Second, by operating the shower discharge button (24) of the shower switch, the electromagnetic water stop valve (34) is opened to discharge water, and the shower stop button (23)
This operation closes the electromagnetic water stop valve (34) and stops the shower discharge. Third, also the shower discharge button (2
4) starts a timer (not shown), starts subtracting the usable time, and displays the remaining discharge time on the display (25).
). The display of the first usable time on the display (25) can also be performed on the condition that the usage card is accepted (42). Fourth, due to the operation of the above-mentioned timer, the remaining discharge time is less than a certain amount of time (for example, 3 minutes, 1 minute, etc.)
When this happens, the alarm buzzer (2B) generates a warning sound. Fifth, immediately after operating the shower discharge button (20) or after a certain period of time, the ventilation fan (8), (19
). The ventilation fans (8) and (19) are stopped after a predetermined period of time has elapsed. The conditions for starting and stopping the ventilation fans (8) and (19) can be arbitrary as required. For example, the ventilation fans (8) and (19) may be stopped after a certain period of time has passed after the door lock (4z) is released. Good, and a ventilation fan (8) during and after shower use.

It is also possible to change the rotation speed of (19). Sixth,
After the shower discharge time (that is, the calculation means (40b)
) After a certain period of time (for example, 1 minute) has elapsed, the wash valve (18) is opened for a certain period of time to wash the floor of the shower sub-compartment (lb). In addition, there is an emergency button (29) inside the compartment (1).
) is provided, and if the user feels something abnormal and operates this emergency button (28), an emergency lamp (48) will be activated.
It flashes and also sounds an alarm buzzer.

Next, the operation of the embodiment of the present invention will be explained. When a person wishing to take a shower stands in front of the door (2) of the compartment (1), either the hot water tank temperature (43) is low, the water storage tank water level (44) is low, or both conditions occur. , control unit) (40) is the lamp (46) being prepared.
) and lock the door (2). Therefore, it is not possible to enter compartment (1) at this time.
If the hot water storage tank temperature (43) is above the predetermined temperature and the water storage tank water level (40) is above the predetermined water level, it can be used and this lamp (46) will not be lit and the door (2) will be turned on.
In this case, a usable lamp (not shown) may be turned on.

A user enters the compartment (1) and opens the door (2).
When the door is locked, the lamp (47) in use is lit and a door lock signal (41) is generated, which causes the control unit to
(40) is a timer (not shown) of the calculation means (40a)
Activate. This timer generates an alarm if the usage card reception signal (42) is not generated even after a certain period of time (for example, 3 minutes) has elapsed after the door lock signal (41) was generated. If the usage card is properly accepted, the usage card reception signal (42) will be generated, and the input conditions (41 to 44) will be generated.
are aligned, the calculation means (40a) is the calculation means (40b)
A command signal to that effect is sent to the shower switch (23).
), (24) are enabled. When the shower discharge button (24) of the shower switch is operated, the control 22 (40) commands to open the electromagnetic water stop valve (31), and shower water is discharged from the shower head (21).

At the same time, a timer (not shown) of the calculation means (40b) is started and the remaining ejection time is displayed on the display (25). Also, at this time, the control unit ) (40) is the ventilation fan (8), (
19). If you operate the shower stop button (23) before the shower available time ends,
The timer is stopped and the display on the display (25) is also maintained. When the remaining discharge time of the shower becomes less than a predetermined time, the calculation means (40b) detects this and sounds the alarm buzzer (2B).When the usable time of the shower monitored by the calculation means (40b) ends, the control The unit (40) commands the electromagnetic water shutoff valve (31) to close, and the shower switch (
The shower discharge will stop regardless of the operation in step 23).

After a certain period of time (for example 3 minutes), the control 22 (40) commands the flush valve (18) to open and flush the floor of the shower sub-compartment (1b).

When the user unlocks the door to exit the compartment (1), all timers, counters, memories, etc. of the control unit (40) are reset to their initial state. At this time, the card rejection condition of the usage card acceptance determination means of the control unit (40) is canceled and the 1gt card can be accepted. However, ventilation fans (8), (19)
) and floor cleaning using the valve (18) are continued for a predetermined period of time. The monitoring alarm for abnormalities occurring between the time the user enters the room and the time the user leaves the room has been described in the configuration of the embodiment.

Moreover, although a train has been taken as an example above, it is clear that a similar configuration is possible for large automobiles and shower rooms at sports facilities and the like.

(Effects of the Invention) According to the present invention, as described above, by configuring a system that systematically performs the entire process from setting the conditions for using the shower to the end of use, including cleaning, It is possible to obtain a highly reliable shower system that fully considers user safety and maintenance management.
