Although not shown in FIG. 1, the toilet lighting and the like may be turned off. The above-mentioned equipment protection operation may be possible even in the normal operation state as long as the urinal 110 is not in use.

Further, in the standby state, the display device 30 indicates to the display unit 36 that the toilet is not used or is absent (no user) by the control unit 32.

Next, when the entry of the user is detected by the entry detection sensor 26 of the entry detection device 20, the control unit 22 of the entry detection device 20 enters the communication unit 14 of the system management device 10 through the communication unit 24 or signals that the user is in the room. To send. When the system management device 10 receives the entry detection signal by the communication unit 14, the control unit 12 transmits the entry or occupancy signal to the display device 30 and the urinal system 100 through the communication unit 14.

When the communication unit 34 receives the room entry or occupancy signal, the display device 30 switches the control unit 32 to the occupancy display state. When the control unit 32 is in the occupancy display state, the display unit 36 displays that the user is in the room. Although not shown in FIG. 1, when the toilet lighting or the like is turned off in the absence state, it may be turned on by the entry or presence signal in the same manner.

Further, when the urinal system 100 receives the entry or occupancy signal by the communication unit 113, it is changed to the normal operating state. When the urinal system 100 is in the normal operating state, the human body detection unit 114 and that is, the detection unit 116 are operated. Then, when the human body detection unit 114 detects the approach of the user to the urinal 110, the urinal control unit 134 transmits a urinal use start signal to the system management device 10 via the communication unit 113. When the control unit 12 of the system management device 10 receives the urinal use start signal by the communication unit 14, the control unit 12 adds the number of times the urinal is used. When the number of times the urinal has been used by the control unit 12 of the system management device 10 reaches a predetermined number of times, the control unit 12 transmits a cleaning promotion signal to the display device 30 via the communication unit 14. When the display device 30 receives the cleaning promotion signal from the communication unit 34, the control unit 32 displays to the display unit 36 to urge the administrator to clean. As a result, the urinal 110 can be cleaned every predetermined number of times of use, and the urinal 110 can be kept clean.
It should be noted that the number of times the cleaning promotion signal is transmitted can be determined by the number of operations of cleaning (main cleaning) after use, which will be described later.

Further, when the control unit 12 of the system management device 10 receives the urinal use start signal from the communication unit 14, the communication unit 14 transmits the urinal use start signal to the display device 30. When the display device 30 receives the urinal use start signal in the communication unit 34, the display unit 36 displays that the urinal is in use.

When the urinal system 100 is set to perform pre-use cleaning (pre-cleaning), when the human body detection unit 114 continuously detects the user on the urinal 110 for a predetermined time, the urinal The control unit 134 transmits a pre-cleaning start signal from the discharge unit 120 to the urinal main body 112 to the system management device 10 via the communication unit 113 before the start of discharge of the cleaning water by the pre-cleaning. When the control unit 12 of the system management device 10 receives the pre-cleaning start signal by the communication unit 14, the control unit 12 adds the number of pre-cleaning executions. After that, after the cleaning water by the pre-cleaning is discharged from the discharge unit 120 to the toilet body 112, the urinal control unit 134 transmits the pre-cleaning end signal to the system management device 10 via the communication unit 113. The number of operations can be obtained by transmitting signals for cleaning after use (main cleaning) and each operation in the standby state, which will be described later, and can be used as detection information for parts replacement time of the water supply unit 132.

Next, when the human body detection unit 114 detects that the user has left the urinal 110, the urinal control unit 134 transmits a urinal use end signal from the communication unit 113 to the system management device 10. The timing of transmitting the urinal use end signal is before the start of discharging the washing water from the discharge unit 120 to the toilet body 112 or after the discharge is completed. When the system management device 10 receives the urinal use end signal from the communication unit 14, the communication unit 14 transmits the urinal use end signal to the display device 30. When the display device 30 receives the urinal use end signal from the communication unit 34, the display device 30 ends the display indicating that the urinal is used on the display unit 36.

When the human body detection unit 114 detects that the user has left the urinal 110, the urinal control unit 134 determines that the use has been completed, operates the water supply unit 132, and supplies water to the discharge unit 120. Then, the cleaning water from the main cleaning is discharged from the discharge port 115A of the spreader portion 115 to the toilet bowl main body 112 to clean the toilet bowl main body 112. After the wash water is discharged from the discharge unit 120, when the detection unit 116 detects that the wash water in the bowl unit 112A has been drained within a predetermined time, the urinal control unit 134 is blocked in the drain port of the urinal. Is not generated. In this way, when the urinal control unit 134 determines that the urinal drainage port is not clogged, the communication unit 113 transmits a clog-free signal to the system management device 10. It should be noted that the timing of transmitting this, that is, the non-generation signal is performed at a timing such as after the discharge of the washing water is not discharged from the discharge unit 120 to the toilet bowl main body 112. In addition, if clogging does not occur, it may not be transmitted.

Further, after the washing water is discharged from the discharge unit 120, when the detection unit 116 detects that the washing water in the bowl unit 112A has not been drained within a predetermined time, the urinal control unit 134 drains the urinal. It is determined that the mouth is clogged. Then, when the urinal control unit 134 determines that the clogging has occurred, the communication unit 113 transmits the clog generation signal to the system management device 10. It should be noted that the timing of transmitting this generation signal is such that the washing water is not discharged from the discharge unit 120 to the toilet body 112 after the discharge is completed. When the system management device 10 receives the generation signal in the communication unit 14, the system management device 10 transmits the generation signal from the communication unit 14 to the display device 30. When the display device 30 receives the generation signal by the communication unit 34, the control unit 32 displays on the display unit 36 that the urinal 110 is clogged. By confirming the display of the display unit 36, the toilet manager can remove the clogging of the urinal 110 at an early stage.
Further, when the urinal control unit 134 determines that clogging has occurred, the water supply operation from the water supply unit 132 to the water discharge unit 120 is stopped, and the overflow from the bowl unit 112A is also prevented. The stop of the water supply operation may be due to an instruction signal from the system management device 10 side.
