Each sensor 1a-6a is for detecting a human body close to each toilet 1-6. In this embodiment, the sensor 1a-6a is composed of a radio wave sensor that detects a human body by radio waves. It may be. If it is a radio wave type sensor, it can be installed without opening a sensor opening in a toilet bowl, toilet seat box, low tank cover or the like. Moreover, communication between the toilet bowls 1-6 is possible by the electromagnetic wave of the same frequency band as this sensor. Note that the sensor 1a of the urinal 1 closest to the entrance / exit 14 has a larger (wider) detection area than the other sensors 2a to 6a so as to detect a human body near the entrance / exit 14. In this embodiment, the urinal 1 is a first toilet device, and the urinals 2 and 3 and the urinals 4 to 6 are second toilet devices.

  In each of the urinals 1 to 3, an automatic cleaning device (shown in the figure) performs cleaning (flowing water through the urinal) when the human body stays in front of the urinal for a predetermined time (for example, about 5 to 60 seconds) or more and then moves away. Abbreviation) is installed.

  The toilet bowls 4 to 6 are provided with a toilet lid automatic opening / closing device that raises the toilet lid when the human body approaches within a predetermined distance and closes the toilet lid when the human body leaves. Each of the toilets 4 to 6 includes a heating toilet seat automatic control device that turns on the heating toilet seat when the human body approaches within a predetermined distance and turns off the heating toilet seat when the human body leaves, and when the human body moves away from the toilet bowl, An automatic cleaning device is installed for automatic cleaning.

  In this embodiment, when the sensor 1a detects the human body (specifically, when the sensor 1a detects the human body and then no longer detects the human body), the urinals 2 and 3 In addition, a control device with a timer for n minutes is provided which transmits a sensor operation start signal to the toilets 4 to 6 and transmits a sensor operation stop signal when a predetermined time (n minutes) elapses. Each of the urinals 2 and 3 and the urinals 4 to 6 is provided with a sensor control device that receives the sensor operation start or stop signal and starts or stops the operation of the sensors 2a to 6a based on the received signal. Yes.

  The sensor 1a is configured to always perform a human body detection operation, and the sensors 2a to 6a operate for a predetermined time (n minutes) after receiving the operation start signal from the urinal 1 as shown in FIG. The n minutes are preferably selected from 1 to 10 minutes, particularly from 1 to 3 minutes.

  An operation example of the sensors 2a to 6a will be described with reference to FIGS. FIG. 2 shows a case where a person enters the toilet room 15 from the entrance 14 and exits using only the urinal 1.
