Description

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

(Prior art) A shower room that allows the door of the shower room to be opened by inserting a coin, locks it from the inside to prevent the insertion of another coin, and allows hot water to be supplied for a predetermined period of time. The equipment is
It is disclosed in Japanese Utility Model Application No. 57-12092.

Further, Japanese Utility Model Publication No. 126881/1981 discloses a technique for controlling the time during which a shower room can be used and the time during which the shower can be used (hot water tap time) according to the number of coins inserted.

(Problem that the invention aims to solve) However, conventional shower equipment allows entry by inserting a coin, or allows use of the shower for a predetermined time, and can supply hot water at an appropriate temperature. It is not configured to monitor whether or not the condition is met, and to permit coin insertion only when hot water supply at an appropriate temperature is possible.

For this reason, there is a possibility that the user may not be able to take a shower at the desired temperature even after inserting a coin.

In addition, since many people are using shower equipment installed in public places for the first time, check the operating status of the equipment, such as whether the shower equipment is in a usable state and whether the card used can be read. There was a desire for something that would display information in an easy-to-understand manner and guide the necessary operating procedures.

This invention was made to solve these problems, and the purpose is to provide a shower system that clearly informs the user of the status of the shower equipment and allows them to perform corresponding operations.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the shower system according to this invention includes a usage card acceptance device in the compartment, and a control system that enables the shower to be used for a predetermined time based on the reading of the usage card. In a shower system equipped with a shower unit, a display means is provided on the usage card acceptance device for reading the usage card, and the control unit also controls whether the shower is used when the temperature of hot water that can be supplied for the shower is within a predetermined range. The present invention is characterized in that a display indicating that the user card can be accepted is displayed when the door for entering and exiting the compartment is locked.

(Function) The control unit displays that the shower can be used if hot water at a predetermined temperature can be supplied. Then, when the door for entering and exiting the compartment is locked, a display is made to the effect that the usage card can be accepted.

Therefore, even a first-time user can easily know the status of the shower equipment and perform necessary operations based on the displayed operation guidance.

Furthermore, since the usage card can be accepted after the door is locked, it is safe and there is no need to forget to lock the door.

(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.

For example, this display means 70 uses a liquid crystal display, and displays "Preparing" when the hot water temperature 43 in the hot water storage tank is below a predetermined value, and displays "Open" when the hot water temperature 43 is above a predetermined value. Perform display.
At this time, when "open for business" is displayed, the control unit 40 flashes a display indicating that the door 2 of the compartment 1 should be locked. If the door is locked while this "Open for Business" is displayed, the display means 70 displays "Card Acceptance" indicating that the card can be accepted, and then after the card is accepted, displays "Shower discharge ready" to indicate that the shower is ready for use.

Furthermore, once the usage card accepting device 70 has received the usage card once, it will not accept the next new usage card unless the door lock of the door 2 is released after using the shower. It is also displayed that the usage card cannot be accepted, and this display is made, for example, after the shower starts discharging water.
Acceptance, refusal of acceptance, and display of such usage cards are controlled by a control unit 40, which will be described later. One use card can only be used once (for example,
8 minutes) was made available 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 shelf 16, a grip bar 17 to prevent falling, a washing water spout 18, and an automatically operated ventilation fan 19. are doing.

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 (none of which are 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, usage card acceptance 42, hot water tank temperature 43, and water storage tank water level 44 are appropriate, and sends a predetermined command signal. Achieve five functions such as.
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 7 of the device 7 is turned on.
0 is displayed as "Preparing". On the other hand, when the temperature of the hot water in the hot water storage tank is above a predetermined value, the lamp 46 indicating that the shower is in preparation is not turned on, and the display means 70 is displayed as "open for business".
Second, when the condition of the door lock 41 occurs when the shower user enters the compartment 1 and locks the door 2, the lamp 47 indicating that the shower is in use is turned on, and the display means 70 displays "Card accepted". . 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. When the door lock 41 and usage card acceptance 42 conditions occur, the display means 70 displays "Shower discharge possible". Fourthly, even if the door lock 41 and usage 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 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 is opened 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.

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, the card accepting device 7 cannot accept the card, and the display means 70 displays "Preparing". When the hot water storage tank temperature 43 is above a predetermined temperature and the water storage tank water level 44 is above a predetermined water level, the user who enters the compartment 1 can only accept a card by locking the door 2, and the display means 70 Display “Card Acceptance”. Also, lamp 4 in use at this time
7 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 card acceptance signal 41 is not generated even after a certain period of time (for example, 3 minutes) has elapsed after the door lock signal 41 was generated. When the usage card is properly accepted, the usage card acceptance signal 41 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 switch 23, 24 operations are possible. At this time, the display means 70 is displaying "Shower discharge possible". When the shower discharge button 24 of the shower switch is operated, the control unit 40 instructs the electromagnetic water stop valve 31 to open, 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 controls the ventilation fans 8 and 19.
Activate. 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. When the usable time of the shower monitored by the calculation means 40b 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.

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 card rejection condition of the usage card acceptance determination means of the control unit 40 is canceled, and a new card can be accepted. However, ventilation by ventilation fans 8 and 19 and valve 18
The floor cleaning 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.

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 such as sports facilities.

Further, although the display means 70 in the embodiment uses a liquid crystal display, this display means may also be a voice display equipped with a voice synthesizer or the like.
Furthermore, both may be used together.

(Effect of the invention) As explained above, the shower system according to this invention displays a message that the shower can be used when the temperature of hot water that can be supplied for showering is within a predetermined range, and allows entry and exit from the compartment. When the door is locked,
Since the system is configured to display that a usage card can be accepted, the user can easily know the status of the shower equipment and can perform the necessary operations according to the operation guide display.
