A preferred embodiment of the present invention will be described.

In the toilet system of the present invention, the control unit determines, based on a change in the detection result of the detection unit, that the private toilet room has changed from a state immediately after the start of use to a state in use, or the private toilet room is At least one of determining that the state has changed from the state in use to the state immediately before the end of use can be performed. In this case, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

In the toilet system of the present invention, when determining that the private toilet room is in a state immediately before the end of use, the control unit determines that the private room is in the state immediately before the end of use only when a plurality of predetermined conditions are satisfied. can be determined to be in the state of In this case, for example, a plurality of conditions are set in advance to eliminate the determination that the toilet cubicle is in a state just before the end of use for 10 seconds after the toilet cubicle starts to be used. Thus, erroneous determination can be prevented. As a result, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

In the toilet system of the present invention, the control unit can determine that the state has changed to the in-use state when the detection unit detects a predetermined state after determining that the private toilet room is in a state immediately before the end of use. In this case, the situation in the toilet compartment can be monitored even after the notification that the toilet is in a state immediately before the end of use, and the content of the notification can be returned to "in use" according to the situation. Therefore, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

Next, Embodiments 1 to 7 embodying the toilet system of the present invention will be described with reference to the drawings. The toilet systems of Examples 1 to 7 are provided in the toilet facility 1 shown in FIG. The toilet facility 1 includes a door 2 at the entrance, a shared space 3 inside the door 2, a washbasin 4 arranged in the shared space 3, and a plurality of toilet facilities provided partitioned from the shared space 3 (Fig. 1 and 3 toilet private rooms 10 in the middle.

Each toilet cubicle 10 is provided with a door 11, a toilet device 12, a paper holder 13, and a remote control 14, respectively. A door 11 is a door for entering and exiting each toilet room 10 . The toilet device 12 is a toilet device with a toilet seat device having a warm water washing function. A paper holder 13 rotatably holds the roll paper. The remote controller 14 is provided with various switches for operating the toilet device 12, such as opening and closing the toilet seat and toilet lid, cleaning the local area, and cleaning the toilet bowl.

Further, each toilet compartment 10 is provided with a door lock sensor 21, a seating sensor 22, a rotation sensor 23, and a toilet cleaning switch 24 as detection units for detecting the conditions inside the toilet compartment 10. FIG. A door lock sensor 21 detects whether the door 11 is locked. The seat sensor 22 detects whether or not the user is seated on the toilet seat of the toilet device 12 . A rotation sensor 23 detects whether the roll paper is rotating. A toilet cleaning switch 24 is a switch for cleaning the toilet and is provided on the remote controller 14 . These door lock sensor 21 , seating sensor 22 , rotation sensor 23 and toilet cleaning switch 24 are connected to and controlled by the control section 30 . Further, detection results by the door lock sensor 21 , the seating sensor 22 , the rotation sensor 23 , and the toilet cleaning switch 24 are transmitted to the control section 30 . The control unit 30 determines the state of use of the private toilet room 10 based on these detection results. The notification unit 40 notifies the result of determination by the control unit 30 . The notification unit 40 is a display device that displays the determination result of the control unit 30 in characters or figures. The notification unit 40 is arranged on the outer wall of the toilet equipment 1 . The notification unit 40 notifies information about the usage status of each toilet room 10 .

In normal use for the purpose of defecation, the user of the toilet cubicle 10 includes actions incidental to defecation, such as locking, undressing, sitting, cleaning the private area, rolling up roll paper, wiping the private area, removing the seat, cleaning the toilet bowl, dressing, It is assumed that an operation such as unlocking is performed. Among these operations, locking and unlocking are operations performed at the start of use of the private toilet room 10 (at the time of entering) and at the end of use (at the time of leaving), respectively. For this reason, in the toilet systems of Examples 1 to 7, the detection of locking and unlocking by the door lock sensor 21 allows the private toilet room 10 to be in an "empty" state, in which the private toilet room 10 is not in use, and the private toilet room 10 is in use. Determines the state of "in use", which is the state of being in use.

Also, some of the actions described above are performed in random order before or after defecation, depending on the user. On the other hand, for example, locking, undressing, and sitting are actions before defecation, and local washing, local wiping, toilet cleaning, unseat, dressing, unlocking, etc. are actions after defecation. The motions before defecation are performed at a relatively early stage after entering the private toilet room, prior to other motions, and the motions after defecation are performed at a relatively late stage after entering the private toilet room and before leaving the private room. This is the action to be taken. Examples 1 to 7 focus on one or more of these actions before and after defecation. Then, by directly or indirectly detecting these actions as the situation in the private toilet room, the state immediately before the end of use, which is the state in which the private toilet room is in use, or the state immediately before leaving the room, or even after entering the room. A state immediately after the start of use, which is a state in which there is no battery, is determined.

<Example 1>
The toilet system of Example 1 is configured with a door lock sensor 21 and a seating sensor 22 as detection units, and a control unit 30 . This toilet system detects the situation in the toilet cubicle 10 by detecting whether or not the door is locked by the door lock sensor 21 and whether or not the seat is seated by the seating sensor 22 . The control unit 30 determines the state of use of the private toilet room 10 based on these detection results. Also, the control unit 30 outputs a signal including this determination result. In the case of this embodiment, the output signal is transmitted to the notification section 40 . The notification unit 40 notifies the determination result by the control unit 30 by receiving the output signal.

Control processing of the toilet system having the above configuration will be described with reference to the flow chart of FIG. 2 and the timing chart of FIG. First, as shown in FIG. 2, in step S101, it is determined whether the door 11 is locked. A door lock sensor 21 determines whether the door 11 is locked.

In step S101, when it is determined that the door 11 is locked (the door lock sensor 21 is turned on), the control unit 30 determines that the toilet cubicle 10 is in use (step S102), and the notification unit 40 notifies that effect (step S103). That is, as shown in FIG. 3, when the door lock sensor 21 is switched from off to on, the notification content of the notification unit 40 is switched from "idle" to "in use".

It is determined that the toilet cubicle 10 is empty when it is detected that the door 11 is not locked, that is, the door lock sensor 21 is in the OFF state. This "vacant" state is a state in which there is no user in the private toilet room 10 . On the other hand, whether the toilet cubicle 10 is in use is determined by detecting that the door 11 is locked, that is, by detecting that the door lock sensor 21 is on. This "in use" state is a state in which a user is in the private toilet room 10 .

Next, in step S104, it is determined whether or not the user of the private toilet room 10 is seated on the toilet seat of the toilet device 12 or not. A seating sensor 22 determines whether or not the passenger is seated. That is, when the seating sensor 22 is on, it is determined that the person is seated, and when it is off, it is determined that the person is not seated. If it is determined that the user is seated because the seat sensor 22 is ON, the process proceeds to step S105. In step S105, it is determined whether or not the user of the toilet cubicle 10 has left the toilet device 12, that is, whether or not the seating sensor 22 in the on state has turned off. In the toilet system of the first embodiment, the controller 30 determines that the toilet cubicle 10 is in a state immediately before the end of use when it determines that the user has left the seat. That is, the determination "immediately before the end of use" in the first embodiment is made by determining that the user has left the seat.

If it is determined in step S105 that the user has left the seat (the seating sensor 22 is turned off), the control unit 30 determines that the toilet cubicle 10 is in a state immediately before the end of use (step S106). A determination result is output to the notification unit 40 . Then, the notification unit 40 notifies that it is "immediately before the end of use" as the determination result of the control unit 30 (step S107). That is, as shown in FIG. 3, by switching the seating sensor 22 from ON to OFF, the notification content of the notification unit 40 is switched from "during use" to "immediately before the end of use". In this way, the control unit 30 changes the state of the toilet cubicle 10 from the state in use to the state just before the end of use based on the change in the detection result of the seating sensor 22 as the detection unit from the ON state to the OFF state. It is determined that

Then, in step S108, it is determined whether or not the door 11 is unlocked. When it is determined that the door lock sensor 21 is unlocked (the door lock sensor 21 is turned off), the control unit 30 determines that the toilet cubicle 10 is vacant (step S109), and the notification unit 40 notifies to that effect. (Step S110). That is, as shown in FIG. 3, when the door lock sensor 21 is switched from ON to OFF, the notification content of the notification unit 40 is switched from "immediately before the end of use" to "empty".

On the other hand, if it is determined that the door 11 is not unlocked (the door lock sensor 21 is ON), the process proceeds to step S111 to determine whether the user of the private toilet room 10 has sat on the toilet seat of the toilet device 12 again. to judge. This is based on the assumption that the user of the private toilet room 10 may have another urge to defecate and sit down again before unlocking. In this case, assuming that the private toilet room 10 will not be available soon, the content of the notification "immediately before the end of use" is returned to "in use". Specifically, when it is determined again that the vehicle is seated (the seating sensor 22 is turned on) in step S111, the control unit 30 determines that the vehicle is in use in step S112. In this case, the notification unit 40 notifies "in use" again in step S113, and returns to step S105. Thus, in the toilet system of the first embodiment, after determining that the toilet cubicle 10 is in a state immediately before the end of use, when the seating sensor 22 as the detection unit detects seating as a predetermined situation, control is performed. The unit 30 determines that the state of the private toilet room 10 has changed from the state immediately before the end of use to the state of being in use.

If the door is unlocked without detection of seating in step S104, it is not determined that the state is just before the end of use. You can switch directly to the "empty" announcement. That is, the toilet system of the first embodiment determines that the toilet cubicle 10 is in a state immediately before the end of use in subsequent processing only when locking and seating after locking are detected as a plurality of predetermined conditions. .

As described above, the toilet system of the first embodiment includes the door lock sensor 21 and the seating sensor 22 as detection units for detecting whether the toilet compartment 10 is locked or not, and whether or not the person is seated. Based on the detection result of the sensor 22, it is determined whether the private toilet room 10 is in an empty state or in use, and in the state in use, it is determined that the private toilet room 10 is in a state just before the end of use. and a control unit 30 for outputting a signal containing the results of these determinations.

The toilet system of the first embodiment detects whether or not the door lock sensor 21 is locked and whether or not the seat sensor 22 is seated in order to detect the situation in the toilet cubicle 10, and detects two states: an empty state and an in-use state. As another type of state, the state immediately before the end of use is determined, and a signal including this determination result is output. In this way, the toilet system of Example 1 can inform the outside whether or not the private toilet room will become available soon.

Therefore, the toilet system can provide more detailed toilet usage status.

Further, the control unit 30 determines that the state of the private toilet room 10 has changed from the state in use to the state immediately before the end of use based on the change in the detection result of the seating sensor 22 as the detection unit. Therefore, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

Further, when determining that the private toilet room 10 is in a state immediately before the end of use, the control unit 30 detects that the private toilet room 10 is locked and seated after being locked as a plurality of predetermined conditions. It is determined that the state is just before the end of use. As a result, erroneous determination can be prevented. As a result, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

Further, after the control unit 30 determines that the toilet cubicle 10 is in a state immediately before the end of use, when the seating sensor 22 as the detection unit detects the seating as a predetermined situation, it is determined that the state has changed to the in-use state. judge. As a result, the situation in the private toilet room can be monitored even after the notification that the toilet is in a state immediately before the end of use, and the content of the notification can be returned to "in use" according to the situation. Therefore, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

<Example 2>
Next, a toilet system according to a second embodiment will be described. In addition, in the second embodiment, the same symbols are attached to substantially the same components as the toilet seat device of the first embodiment, and the description of the structure, action and effect is omitted.

The toilet system of Example 2 is different from Example 1 in that it has a toilet cleaning switch 24 in addition to the door lock sensor 21 and the seating sensor 22 of Example 1 as detection units. That is, the toilet system of the second embodiment detects the state of the toilet cubicle 10 by detecting whether the door is locked by the door lock sensor 21, by detecting whether the person is seated by the seating sensor 22, and by detecting whether the toilet cleaning switch 24 is being operated. . Based on these detection results, the control unit 30 determines the state of use of the private toilet room 10 and outputs a signal including this determination result. A signal output from the control unit 30 is transmitted to the notification unit 40 . The notification unit 40 that has received the signal notifies the result of determination by the control unit 30 .

Control processing of the toilet system having the above configuration will be described with reference to the flow chart of FIG. 4 and the timing charts of FIGS. As shown in FIG. 4, in the toilet system control process of the second embodiment, it is detected whether or not the door 11 is locked in step S201, and when it is determined that the door 11 is locked (the door lock sensor 21 is turned on), determines that the toilet cubicle 10 is "in use" by the control unit 30 (step S202), and notifies it by the notification unit 40 (step S203). That is, as shown in FIGS. 5 and 6, when the door lock sensor 21 is switched from off to on, the notification content of the notification unit 40 is switched from "idle" to "in use". These steps S201 to S203 are the same as steps S101 to S103 of the first embodiment. However, in the control process of the toilet system of the second embodiment, the determination by the control unit 30 that the user is in a state immediately before the end of use is based on the fact that the seat sensor 22 has detected that the user has left the seat and the toilet flushing switch 24 has been operated. The control process differs from the control process of the first embodiment in that it is performed when is detected.

Specifically, in step S204, it is determined whether or not the user of the toilet cubicle 10 is seated on the toilet seat of the toilet device 12. If it is determined that the user is seated (the seat sensor 22 is turned on), then is detected (steps S205, S210) and whether the toilet bowl is being washed (steps S206, S209). In the toilet system of Example 2, as in Example 1, only when locking and seating after locking are detected as a case where a plurality of predetermined conditions are satisfied, the toilet cubicle 10 is in a state immediately before the end of use. Make a judgment. The judgment that the toilet cubicle 10 is in a state immediately before the end of use is made by detecting whether or not the seat has been removed and whether or not the toilet bowl has been cleaned.

In step S205, it is detected whether or not the seat has been removed. If it is determined in step S205 that the user has left the seat (seat sensor 22 is turned off), then in step S206 it is determined whether or not the toilet bowl has been washed. do. That is, the judgment as to whether or not the toilet bowl has been washed in step S206 is made after leaving the seat. When it is determined that both the user has removed the seat (the seat sensor 22 is turned off) and the toilet bowl has been cleaned (the toilet bowl cleaning switch 24 has been turned on), the control unit 30 determines that the toilet cubicle 10 is in a state immediately before the end of use. Determine (step S207). A determination result is output to the notification unit 40 . Then, the notification unit 40 notifies "immediately before the end of use" as the determination result of the control unit 30 (step S208). That is, as shown in FIG. 5, when the seating sensor 22 is first switched from ON to OFF and then the toilet bowl cleaning switch 24 is operated, the content of the notification of the notification unit 40 when the toilet bowl cleaning switch 24 is operated is switched from "in use" to "immediately before use ends".

On the other hand, if it is determined in step S205 that the user has not left the seat (seating sensor 22 is ON), the process proceeds to step S209. In step S209, it is determined whether or not the toilet bowl has been washed, as in step S206. If it is determined in step S209 that the toilet has been washed (toilet cleaning switch 24 is turned on), the process proceeds to step S210, and if it is not determined that the toilet has been washed, the process returns to step S205. If it is determined in step S209 that the toilet has been washed, it is determined in step S210 whether or not the user has left the seat. If it is determined that the user has left the seat, the process proceeds to step S207. In this way, when it is determined that both toilet flushing (toilet flushing switch 24 is turned on) and seating removal (seating sensor 22 is turned off) are performed, the control unit 30 determines that the toilet cubicle 10 is in a state immediately before the end of use. Determine (step S207). Then, the notification unit 40 notifies "immediately before the end of use" as the determination result of the control unit 30 (step S208).

That is, as shown in FIG. 6, when the toilet cleaning switch 24 is operated while the seating sensor 22 is on, the seating sensor 22 is switched off after the toilet cleaning switch 24 is operated. The notification content of the notification unit 40 is switched from "in use" to "immediately before the end of use". At this time, the control unit 30 determines that the state of the private toilet room 10 has changed from the state in use to the state immediately before the end of use based on the change in the detection result of the seating sensor 22 as the detection unit from ON to OFF.

As described above, in the control process of the second embodiment, determination is made based on the detection results of the two detection units that detect the presence or absence of the two actions of seating and flushing the toilet. The processing is performed by assuming two patterns, one in which the toilet bowl is cleaned in the state in which the seat is removed, and the other in which the toilet bowl is cleaned in the state in which the seat is not removed. Further, the control unit 30 operates based on a change in the detection result from the ON state to the OFF state of the seating sensor 22 as a detection unit and a change in the detection result from the OFF state to the ON state of the toilet flushing switch 24. Then, it is determined that the toilet cubicle 10 has changed from the state in use to the state just before the end of use.

The control processing after step S211 is the same as the processing after step S108 in the first embodiment. That is, in step S211, it is determined whether or not the door 11 is unlocked, and if it is determined that the door 11 is unlocked, it is determined that the private toilet room 10 is "empty" (step S212), and that effect is notified. (Step S213). If it is determined that the door 11 is not unlocked, it is determined again whether or not the vehicle is seated (step S214). S215), and "in use" is notified again (step S216). That is, as shown in FIGS. 5 and 6, when the door lock sensor 21 is switched from ON to OFF, the notification content of the notification unit 40 is switched from "Immediately before the end of use" to "Empty".

As described above, the toilet system of the second embodiment includes the door lock sensor 21, the seating sensor 22, and the toilet cleaning switch 24 as detection units for detecting the conditions inside the toilet compartment 10, the door lock sensor 21, the seating sensor 22, and the toilet cleaning Based on the detection result of the switch 24, it is determined that the private toilet room 10 is in an empty state and in use, and in the state in use, it is determined that the private toilet room 10 is in a state immediately before the end of use. and a control unit 30 for outputting a signal containing the results of these determinations.

The toilet system of the second embodiment detects whether or not the door lock sensor 21 is locked, whether or not the seat sensor 22 is seated, and whether or not the toilet flushing switch 24 is being operated. A state immediately before the end of use is determined as another of the two types of states, namely, the vacant state and the in-use state, and a signal containing this determination result is output. Thus, the toilet system of Example 2 can inform the outside whether or not a private toilet room will become available soon.

Therefore, the toilet system of Example 2 is also capable of informing more detailed usage conditions of the toilet.

Further, the control unit 30 determines that the state of the private toilet room 10 has changed from the state in use to the state immediately before the end of use, based on the change in the detection result of the seating sensor 22 and the toilet flushing switch 24 as the detection unit. . Therefore, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

Further, when determining that the private toilet room 10 is in a state immediately before the end of use, the control unit 30 detects that the private toilet room 10 is locked and seated after being locked as a plurality of predetermined conditions. It is determined that the state is just before the end of use. As a result, erroneous determination can be prevented. As a result, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

Further, after the control unit 30 determines that the toilet cubicle 10 is in a state immediately before the end of use, when the seating sensor 22 as the detection unit detects the seating as a predetermined situation, it is determined that the state has changed to the in-use state. judge. As a result, the situation in the private toilet room can be monitored even after the notification that the toilet is in a state immediately before the end of use, and the content of the notification can be returned to "in use" according to the situation. Therefore, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

In addition, the control unit 30 determines that the toilet cubicle 10 is in a state immediately before the end of use, based on the detection results of the two detection units of the seating sensor 22 and the toilet flushing switch 24 as detection units. do. Therefore, compared to the case where the determination is made based on the detection result of one detection unit as in the first embodiment, it is possible to inform the outside of the information as to whether or not the private toilet room will soon become available more precisely and accurately. .

<Example 3>
Next, a toilet system according to Example 3 will be described. In addition, in Example 3, the same reference numerals are given to components that are substantially the same as those of the toilet system of each of the above examples, and the description of the structure, action and effect is omitted.

The toilet system of the third embodiment differs from that of the first embodiment in that it has a rotation sensor 23 instead of the seating sensor 22 of the first embodiment. In other words, the toilet system of the third embodiment detects the situation in the toilet cubicle 10 by detecting whether or not the door lock sensor 21 is locked and whether or not the rotation sensor 23 is rotating the roll paper. Based on these detection results, the control unit 30 determines the state of use of the private toilet room 10 and outputs a signal including this determination result. A signal output from the control unit 30 is transmitted to the notification unit 40 . The notification unit 40 that has received the signal notifies the result of determination by the control unit 30 .

Control processing of the toilet system having the above configuration will be described with reference to the flow chart of FIG. 7 and the timing chart of FIG. As shown in FIG. 7, in the toilet system control process of the third embodiment, the door lock sensor 21 detects whether or not the door 11 is locked in step S301, and the door 11 is locked (the door lock sensor 21 is on). When determined, the control unit 30 determines that the private toilet room 10 is "in use" (step S302), and the notification unit 40 notifies (step S303). That is, as shown in FIG. 8, when the door lock sensor 21 is switched from off to on, the notification content of the notification unit 40 is switched from "empty" to "busy". These steps S301 to S303 are the same as steps S101 to S103 of the first embodiment. However, in the control processing of the toilet system of the third embodiment, the determination by the control unit 30 of the state immediately before the end of use is based on the determination of whether or not the user of the toilet cubicle 10 is winding up the roll paper. done based on Specifically, the rotation sensor 23 detects the presence or absence of rotation caused by the winding of the roll paper, and when the winding is detected, the timer is started, and after a predetermined time has passed, it is determined that the state is about to end. conduct.

Specifically, in step S304, it is determined whether or not the user of the toilet cubicle 10 is winding up the roll paper. , a timer for a predetermined time T1 is started (step S305). After the timer is started, it is determined in step S306 whether winding is stopped. If it is determined in step S306 that the winding is stopped (the rotation sensor 23 is turned off), the process advances to step S307 to wait for the end of the countdown by the timer. While the countdown by the timer continues, the process returns to step S306 to continuously detect whether or not the roll paper is wound.

If it is determined in step S306 that the winding is not stopped (the rotation sensor 23 is turned on) while the timer counts down, the process returns to step S305 to reset the timer and start it again. This is based on the assumption that the roll paper is wound multiple times during one bowel movement. Therefore, as shown in FIG. 8, when it is detected that the roll paper is wound again during the countdown by the timer, the countdown of the timer due to the detection of the previous winding is invalidated, and the predetermined countdown is performed again. A timer starts at time T1.

Then, when it is determined in step S307 that the countdown of the timer has ended, the control unit 30 determines that the use of the private toilet room 10 is about to end (step S308). A determination result is output to the notification unit 40 . Then, the notification unit 40 notifies “immediately before the end of use” as the determination result of the control unit 30 (step S309). That is, as shown in FIG. 8, when the countdown of the timer ends, the notification content of the notification unit 40 is switched from "in use" to "immediately before the end of use". In this way, the control unit 30 activates the timer based on the change in the detection result from the ON state to the OFF state of the rotation sensor 23 as the detection unit. 10 is changed from being in use to being just before the end of use.

Then, in step S310, it is determined whether or not the door 11 is unlocked, and if it is determined that the door 11 is unlocked, it is determined that the private toilet room 10 is "vacant" (step S311), and the fact is notified. (Step S312). That is, as shown in FIG. 8, when the door lock sensor 21 is switched from ON to OFF, the notification content of the notification unit 40 is switched from "immediately before the end of use" to "empty".

As described above, the toilet system of the third embodiment has the door lock sensor 21 and the rotation sensor 23 as the detection unit for detecting the situation in the toilet compartment 10, and based on the detection results of the door lock sensor 21 and the rotation sensor 23, It is determined that the private room 10 is in an empty state and in use, and in the state in use, it is determined that the private toilet room 10 is in a state immediately before the end of use, and a signal containing the results of these determinations is transmitted. and a control unit 30 for outputting.

In the toilet system of the third embodiment, when detecting the situation in the private toilet room 10, the door lock sensor 21 detects whether the door is locked and the rotation sensor 23 detects whether or not the roll paper is wound, thereby determining whether the toilet is empty or in use. As another state of the two types of states, the state immediately before the end of use is determined, and a signal including this determination result is output. Thus, the toilet system of Example 3 can inform the outside whether or not the private toilet room will become available soon.

Therefore, the toilet system of Example 3 is also capable of informing more detailed usage conditions of the toilet.

In addition, the control unit 30 activates a timer based on a change in the detection result of the rotation sensor 23 as a detection unit, and when the countdown of the timer ends, the state of the toilet cubicle 10 changes from the state in use to the state immediately before the end of use. It is determined that it has changed to Therefore, it is possible to more accurately inform the outside of the information as to whether or not the private toilet room will become available soon.

<Example 4>
Next, a toilet system according to Example 4 will be described. In addition, in Embodiment 4, the same symbols are attached to substantially the same components as those of the toilet seat device of each of the above embodiments, and the description of the structure, action and effect is omitted.

The toilet system of Example 4 has a toilet cleaning switch 24 in addition to the door lock sensor 21 and rotation sensor 23 of Example 3 as a detector. That is, the toilet system of the fourth embodiment detects the state of the toilet cubicle 10 by detecting whether or not the door lock sensor 21 is locked, whether or not the roll paper is being rotated by the rotation sensor 23, and whether or not the toilet cleaning switch 24 is being operated. do. Specifically, the control unit 30 determines the state of use of the private toilet room 10 based on these detection results, and outputs a signal including this determination result. A signal output from the control unit 30 is transmitted to the notification unit 40 . The notification unit 40 that has received the signal notifies the result of determination by the control unit 30 .

Control processing of the toilet system having the above configuration will be described with reference to the flow chart of FIG. 9 and the timing chart of FIG. As shown in FIG. 9, in the toilet system control process of the fourth embodiment, the door lock sensor 21 detects whether or not the door 11 is locked in step S401, and the door 11 is locked (the door lock sensor 21 is on). When determined, the control unit 30 determines that the private toilet room 10 is "in use" (step S402), and the notification unit 40 notifies (step S403). That is, as shown in FIG. 10, when the door lock sensor 21 is switched from off to on, the notification content of the notification unit 40 is switched from "idle" to "in use". These steps S401 to S403 are the same as steps S101 to S103 of the first embodiment.

In step S404, it is determined whether or not the user of the toilet cubicle 10 is winding up the roll paper. A timer is started (step S405). Then, when the timer is started, it is determined whether or not winding is stopped (step S406). If it is determined in step S406 that the winding is stopped (the rotation sensor 23 is turned off), the flow advances to step S407 to wait for the end of the countdown by the timer. As long as the countdown by the timer continues, the process returns to step S406 to continuously detect whether or not the roll paper is wound. If it is determined in step S406 that the winding is not stopped (the rotation sensor 23 is on) while counting down the timer, the process returns to step S405 to reset the timer and start it again. These steps S404 to S407 are also similar to steps S304 to S307 of the third embodiment.

Next, in step S408, it is determined whether or not the toilet bowl has been washed, that is, whether or not the toilet bowl washing switch 24 has been operated is detected.

FIG. Then, the notification unit 40 notifies "immediately before the end of use" (step S410). As described above, in the control process of the toilet system of the fourth embodiment, the determination by the control unit 30 of the state immediately before the end of use is made when the toilet cleaning switch 24 is operated, that is, when the toilet cleaning switch 24 is turned on. by being detected. However, as shown in FIG. 10, while the countdown of the timer activated by the rotation sensor 23 continues, even if the toilet flushing switch 24 is detected to be on, it is not determined that the use is about to end. . That is, in the toilet system of the fourth embodiment, the control unit 30 determines that the toilet cubicle 10 is in a state immediately before the end of use, based on the change in the detection result of the toilet flushing switch 24 as the detection unit from off to on. I do. In addition, the control unit 30 detects that winding is in progress as a case where a plurality of predetermined conditions are satisfied, and only when the countdown of the timer that is started when the winding is detected ends. is in a state immediately before the end of use.

Then, in step S411, it is determined whether or not the door 11 is unlocked, and if it is determined that the door 11 has been unlocked, it is determined that the private toilet room 10 is "empty" (step S412), and that effect is notified. (Step S413). That is, as shown in FIG. 10, when the door lock sensor 21 is switched from ON to OFF, the notification content of the notification unit 40 is switched from "immediately before the end of use" to "empty".

As described above, the toilet system of the fourth embodiment includes the door lock sensor 21, the rotation sensor 23, and the toilet cleaning switch 24 as detection units for detecting the situation in the toilet cubicle 10, the door lock sensor 21, the rotation sensor 23, and the toilet bowl.
