Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a shower system, and relates to a shower system that can be used, for example, in medium- and long-distance trains and buses.

(Prior Art) As a public shower facility, one that allows use of the shower by inserting a coin is known. For example, according to Utility Model Application Publication No. 57-12092, a small room (compartment) is used as a public shower facility.
The compartment door opens when a coin is inserted, and after the user enters the compartment, the user locks the door, making it impossible to insert coins and allowing the user to use the shower. . Also, for example,
As in No. 126881, the shower can be used by being equipped with a control device that allows the shower valve to be opened and closed by inserting a coin.

(Problem that the invention attempts to solve) However, according to the first conventional technology, there is no management control over the use of the shower itself, and there is waste due to the shower being left on, and water overflowing due to this. This causes inconvenience. The second conventional technique manages and controls the hot water supply itself based on time, and does not have the disadvantages of the first conventional technique. However, the second prior art discloses a control device that allows the shower to be used only for a certain period of time by inserting a coin.
Nothing is disclosed about the relationship with other devices, such as display of usable time or cleaning management after using the shower. In particular, when installing such a shower system in a vehicle, due to the limited space and vibration, it is necessary to fully consider the safety of the user and from the viewpoint of maintenance management. It is also necessary to systemize the system, but such systemization has not been considered in the prior art.

Therefore, the object of this invention is to provide a shower system that is systematized in various ways, with due consideration given to the safety of the user and the maintenance and management of the shower.

(Means and actions for solving the problem) In order to achieve this purpose, according to this invention,
A shower head 21 that supplies hot water for shower users, a mixing faucet 22 that adjusts the hot water temperature, and a shower switch 2 that starts or stops hot water supply.
3 and 24, a water storage tank and a hot water storage tank provided outside the compartment 1 for supplying water and hot water to the mixing faucet 22, and a door 2 for entering and exiting the compartment 1; A shower system comprising a control unit 40 that enables the shower switches 23 and 24 to be operated by reading a usage card and enables water to be spouted from the shower head 21 only for a predetermined time. If the water temperature is lower than a predetermined value, the usage card will not be accepted, and if the water temperature falls below the predetermined value while using this shower system, the usage card will not be accepted. Each time, a predetermined amount of water is spouted.

According to such a configuration, it is possible to always supply hot water temperature according to the user's preference, and it is also possible to eliminate the problem of the shower water suddenly stopping when the hot water temperature drops. It is possible to maintain and manage the shower.

(Embodiment of the invention) Hereinafter, an embodiment of the invention will be described using a shower system for a vehicle as an example, with reference to the accompanying drawings. Note that the same reference numerals in each figure indicate similar objects.

FIG. 1 shows the interior of a compartment 1 having a vehicle shower system according to an embodiment of the invention. Such a compartment 1 can be provided, for example, in a section of a sleeper train as shown in FIG. The vehicle shown in FIG. 2 has four shower compartments 1 as an example.

Each compartment 1 has a sub-compartment 1a for undressing and a sub-compartment 1a for shower.
It is further divided into compartment 1b. The undressing sub-compartment 1a has a door 2 that can be opened and closed by operating a doorknob 2a that enters the interior from the passageway of the vehicle. This doorknob 2a is equipped with a door lock (not shown) so that it can be locked from the inside. This door lock also functions with an electric switch as described below. A hook 3 is attached to the wall of the sub-compartment 1a on the door 2 side for the shower user to hang his belongings on. In addition, the wall is equipped with a lighting lamp 4, a makeup mirror 5, a towel hanger 6, a usage card insertion device 7, and an automatically operated ventilation fan 8. Furthermore, several shelves 9 are provided on the other wall of this sub-compartment 1a.

Among the above components, usage card acceptance device 7
First, the card (magnetic card,
Various types of cards such as IC cards can be used), and a display means 70 is provided to indicate this. For example, if the door is locked, the display means 70 displays a message that the card can be accepted, and if the door is not locked, it flashes a message indicating that the door should be locked. Furthermore, if the water temperature is below a predetermined value, a display to that effect flashes to indicate that preparations are being made. Also,
After receiving one use card once, the next new use card will not be accepted unless the door lock of door 2 is released after using the shower. It is also displayed that this card cannot be accepted. Acceptance and refusal of such usage cards is controlled by a control unit 40, which will be described later. The reason why one usage card can be used only once (e.g., 8 minutes) is to prevent one person from using the facility for an unnecessarily long period of time, thereby impairing its function as a public facility. The other components of this compartment 1a do not require any special explanation.

The shower sub-compartment 1b is entered from the undressing sub-compartment 1a by opening a door 12 provided in the wall between them. This shower sub-compartment 1b is equipped with a shower operation panel 13, a lighting lamp 14, a soap tray 15, a towel rack 16, a grip bar 17 to prevent falling, a washing water spout 18, and an automatically operated ventilation fan 19. are doing.

1. Mixing faucet 22 for adjusting shower temperature;
Shower stop button 23, shower discharge button 2
4. Shower remaining usage indicator 25, alarm buzzer 2
6, and another shower hanger 27. The functions of these shower operation panels 13 will become clear in the later description. Note that the shower stop button 23 and the shower discharge button 24 will hereinafter be collectively referred to as a shower switch as necessary.

FIG. 4 shows a waterway system of a vehicle shower system having the compartment 1 as described above.
Hot water is supplied to the shower head 21 by guiding water and hot water from a water storage tank and a hot water storage tank (both not shown) provided outside the compartment 1 to the mixing faucet 22 through inlet pipes 31 and 32, respectively. This mixing faucet 22 is a well-known device that mixes and continuously adjusts a predetermined amount of water and hot water so that a predetermined hot water supply temperature specified by, for example, a dial is obtained. 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 adjusted 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 stop valve 34 is connected to the shower switch 23 of the shower operation panel 13,
The shower hot water is discharged from the shower head 21 through an adapter 35 fixed to the wall of the compartment 1.

FIG. 5 shows an electrical system for controlling such a waterway system. The control unit 40 controls the center of the electrical system. The control unit 40 controls a door lock 41, a card acceptance 42, a hot water tank temperature 43, a water tank water level 44, shower switches 23, 24, and an emergency button 29.
With this as the main input condition, the ventilation fans 8 and 19, the cleaning valve 18, the display means 25, the alarm means 26, the electromagnetic water cutoff valve 34, the various display lamps 46 to 48, etc. are operated. The indicator lamps 46 to 48 are installed on the wall on the passage side of the compartment 1 so that the user can check them before entering the compartment 1.
The calculation means 40a of the control unit 40 determines whether the input conditions of the door lock 41, card acceptance 42, hot water tank temperature 43, and water tank water level 44 are appropriate, and sends a predetermined command signal. Achieve the following five functions:
That is, firstly, when the temperature 43 of hot water in the hot water storage tank is lower than a predetermined temperature, and when the water storage tank water level 44 is lower than a predetermined water level,
Lamp 46 indicating that the shower is being prepared
is turned on, the card acceptance by the card acceptance device 7 is stopped, and the display means 70 displays a message to that effect.
Shown below. Second, the door lock 4 where the shower user entered the compartment 1 and locked the door 2.
When condition 1 occurs, the lamp 47 indicating that the device is in use is turned on. Thirdly, when the shower user enters the compartment 1 and locks the door 2, a timer is started 41, and if a usage card is not accepted within a certain time 42, an alarm is generated and unnecessary usage is monitored. do. This situation may occur if the person stays in the compartment for a long time without using the shower. Fourth, even if the door lock 41 and usage card acceptance 42 conditions occur, the shower switches 23 and 24 will remain closed for a considerable period of time.
If the door lock condition 41 is not operated, or 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 48 is flashed. Fifth, the determination that all of the input conditions 41 to 44 are appropriate is transmitted to the calculation means 40b.

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 all of the input conditions 41 to 44 are 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 opens to discharge water. Further, by operating the shower stop button 23, the electromagnetic water stop valve 34 is closed to stop the shower discharge. Thirdly, by operating the shower discharge button 24, a timer (not shown) is started to start subtracting the usable time,
The remaining ejection time is displayed 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 reception 42 is performed.
Fourthly, when the remaining ejection time becomes less than a certain time (for example, 3 minutes, 1 minute, etc.) due to the operation of the above-mentioned timer, the alarm buzzer 26 generates a warning sound. Fifth, the ventilation fans 8 and 19 are activated immediately after the shower discharge button 24 is operated or after a certain period of time has elapsed. 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 set as desired. For example, the door lock 41 may be stopped after a certain period of time has passed after the door lock 41 is released. Further, the rotational speed of the ventilation fans 8 and 19 can be changed during and after using the shower. Sixthly, after the end of the shower discharge time (that is, the calculation means 40b
after the timer stops operating) for a certain period of time (e.g. 1
minutes), the cleaning valve 18 is opened for a certain period of time to clean the floor of the shower sub-compartment 1b. In addition, an emergency button 29 is provided in the compartment 1, and when the user feels something abnormal and operates this emergency button 29, the emergency lamp 48 will flash and the alarm buzzer will sound. be. Seventhly, the above first to sixth operations are based on the input conditions 41 to 44 from the calculation means 40a.
This is performed when all of In this case, the above operation is continued. After this time has elapsed, the calculation means 40a does not accept a card from the next user, and
Lamp 46 indicating that the shower is being prepared
It is set to light up.

Next, the operation of the embodiment of this invention will be explained. When a person wishing to use the shower stands in front of the door 2 of the compartment 1, the control unit 40 turns on the ready lamp 46 under either or both of the following conditions: the hot water tank temperature 43 is low and the water storage tank water level 44 is low. lights up, and at this time compartment 1
Even if the card is entered inside, the card accepting device 7 cannot accept the card, and the display means 70 displays the card. When a hot water storage tank temperature 43 is above a predetermined temperature and a water storage tank water level 44 is above a predetermined water level, a card can only be accepted when the user enters the compartment 1 and locks the door 2. Also, at this time, the lamp 47 in use is turned on, a door lock signal 41 is generated, and the control unit 40 starts a timer (not shown) of the calculation means 40a. This timer generates an alarm if the usage card acceptance signal 42 is not generated even after a certain period of time (for example, 3 minutes) has elapsed after the generation of the door lock signal 41. When the usage card is properly accepted, a coin insertion signal 42 is generated and the input conditions 41 to 44 are met, so the calculation means 40a sends a command signal to that effect to the calculation means 40b, and the shower switches 23, 24 are activated. operation is possible. When the shower discharge button 24 of the shower switch is operated, the control unit 40 instructs the electromagnetic water shutoff valve 31 to open, and the shower water flows into the shower head 21.
Discharge from. 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
starts the ventilation fans 8 and 19. If the shower stop button 23 is operated before the shower usable 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 26. Arithmetic means 40b
When the usable time of the shower monitored by the controller ends, the control unit 40 instructs the electromagnetic water stop valve 31 to close, and the shower discharge is stopped regardless of the operation of the shower switch 23. The above operation is performed when the water temperature in the hot water tank is 43° while the shower is in use.
If the water level 44 becomes less than a predetermined value, or the water level 44 becomes less than a predetermined value, it will continue regardless of the card acceptance conditions, and only the accepted amount will be spouted, and there will be no problem that the water spout will suddenly stop during use. .

Then, after a certain period of time (for example, 3 minutes) has elapsed, the control unit 40 commands the cleaning valve 18 to be opened and the floor of the shower sub-compartment 1b is rinsed.

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 states. At this time, the water temperature in the hot water tank is 4
3 or the water level 44 is not below the predetermined value, the card rejection condition of the usage card acceptance determination means of the control unit 40 is canceled, and a new card can be accepted. These hot water temperature 43 or water level 44
If the value is less than a predetermined value, no further cards will be accepted. In addition, ventilation by ventilation fans 8, 19,
The floor cleaning by the valve 18 is 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.

Furthermore, 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 this invention, as described above, the hot water temperature in the hot water storage tank is one of the conditions for enabling use of the shower, and if the condition is no longer met while the shower is being used, By making it possible to continue using the shower until the end of use, there is no problem of water discharging suddenly stopping, and the system has been constructed to systematically carry out the entire process, including cleaning, until the end of use. By doing so, it is possible to obtain a highly reliable shower system that fully considers user safety and maintenance management.
