Abstract

Provided is a toilet system that can provide more detailed information about a use state of a toilet. The toilet system includes: a detection unit (a door lock sensor, a seating sensor, a rotation sensor, a toilet washing switch, etc.) which detects a situation inside a toilet stall; and a control unit which determines, based on a detection result of the detection unit, that the toilet stall is in a vacant state or in an used state, and further makes at least one of a determination that the toilet stall in the used state is in a state immediately after a start of use and a determination that the toilet stall in the used state is in a state immediately before an end of use, and outputs a signal including determination results.

Claims (20)

1. A toilet system comprising:

a detection unit configured to detect a situation inside a toilet stall; and

a control unit configured to determine, based on a detection result of the detection unit, that the toilet stall is in a vacant state or in a used state, is configured to make at least one of a determination that the toilet stall in the used state is in a state immediately after a start of use or a determination that the toilet stall in the used state is in a state immediately before an end of use, and is configured to output a signal including determination results.

2. The toilet system of claim 1 , wherein the control unit is configured to make, based on a change in the detection result of the detection unit, at least one of a determination that the toilet stall has changed from the state immediately after the start of use to the used state or a determination that the toilet stall has changed from the used state to the state immediately before the end of use.

3. The toilet system of claim 1 , wherein, the control unit is configured to make the determination that the toilet stall is in the state immediately before the end of use once a plurality of predetermined conditions is satisfied.

4. The toilet system of claim 1 , wherein, when the detection unit detects a predetermined situation after the control unit determines that the toilet stall is in the state immediately before the end of use, the control unit is configured to determine that the toilet stall has changed to the used state.

5. The toilet system of claim 1 , wherein the control unit is configured to make at least a determination that the toilet stall is in the state immediately after the start of use.

6. The toilet system of claim 1 , wherein the control unit is configured to make at least a determination that the toilet stall is in the state immediately before the end of use.

7. The toilet system of claim 2 , wherein, the control unit is configured to make the determination that the toilet stall is in the state immediately before the end of use once a plurality of predetermined conditions is satisfied.

8. The toilet system of claim 2 , wherein, when the detection unit detects a predetermined situation after the control unit determines that the toilet stall is in the state immediately before the end of use, the control unit is configured to determine that the toilet stall has changed to the used state.

9. The toilet system of claim 2 , wherein the control unit is configured to make at least a determination that the toilet stall is in the state immediately after the start of use.

10. The toilet system of claim 2 , wherein the control unit is configured to make at least a determination that the toilet stall is in the state immediately before the end of use.

11. The toilet system of claim 3 , wherein, when the detection unit detects a predetermined situation after the control unit determines that the toilet stall is in the state immediately before the end of use, the control unit is configured to determine that the toilet stall has changed to the used state.

12. The toilet system of claim 6 , wherein, the control unit is configured to make the determination that the toilet stall is in the state immediately before the end of use once a plurality of predetermined conditions is satisfied.

13. The toilet system of claim 6 , wherein, when the detection unit detects a predetermined situation after the control unit determines that the toilet stall is in the state immediately before the end of use, the control unit is configured to determine that the toilet stall has changed to the used state.

14. The toilet system of claim 7 , wherein, when the detection unit detects a predetermined situation after the control unit determines that the toilet stall is in the state immediately before the end of use, the control unit is configured to determine that the toilet stall has changed to the used state.

15. The toilet system of claim 10 , wherein, the control unit is configured to make the determination that the toilet stall is in the state immediately before the end of use once a plurality of predetermined conditions is satisfied.

16. The toilet system of claim 10 , wherein, when the detection unit detects a predetermined situation after the control unit determines that the toilet stall is in the state immediately before the end of use, the control unit is configured to determine that the toilet stall has changed to the used state.

17. The toilet system of claim 12 , wherein, when the detection unit detects a predetermined situation after the control unit determines that the toilet stall is in the state immediately before the end of use, the control unit is configured to determine that the toilet stall has changed to the used state.

18. The toilet system of claim 15 , wherein, when the detection unit detects a predetermined situation after the control unit determines that the toilet stall is in the state immediately before the end of use, the control unit is configured to determine that the toilet stall has changed to the used state.
