In step S1, the human body detection means 6 determines whether or not a human body can be detected in front of the toilet 2. If a human body is detected, the process proceeds to step S2. On the other hand, if no human body is detected, step S1 is repeated. When a human body is detected, the toilet lid opening / closing mechanism 8 is controlled to open the toilet lid 3 in step S2, and the toilet lid timer 16 starts counting in step S3.

  Next, in step S4, it is determined whether or not the footwear detecting means 7 can detect the footwear 11. If the footwear 11 can be detected, the process proceeds to step S5. If not detected, the process proceeds to step S10. When the footwear 11 is detected, the toilet seat opening / closing mechanism 15 is controlled to open the toilet seat 4 in step S5, the toilet seat timer 17 starts counting in step S6, and the process proceeds to step S7.

  In step S7, it is determined whether or not the toilet seat timer 17 has passed a predetermined time (for example, 5 minutes). If it has elapsed, the process proceeds to step S8, and if not, step S7 is repeated. When the time has elapsed, the toilet seat opening / closing mechanism 15 is controlled to close the toilet seat 5 in step S8, and the toilet lid opening / closing mechanism 9 is controlled to close the toilet lid 3 in step S9. And it returns to step S1 and it is determined whether a human body is detected again. If the footwear 11 is not detected in step S4, it is determined in step S10 whether the toilet lid timer 16 has elapsed. If it has elapsed, the process proceeds to step S11. If not, step S10 is repeated. In step S11, the toilet lid opening / closing mechanism 9 is controlled to close the toilet lid 3. And it returns to step S1 and it is determined whether a human body is detected again. The above processing is repeated.

  In the present embodiment, as shown in FIG. 5, the presence of the footwear 11 is detected only when it is detected that there is a user in front of the toilet 2. After use, when the user takes off the footwear 11 in front of the toilet 2, the toilet seat 4 is not opened when the footwear is detected without detecting the human body. 4 can be prevented from opening.

  In the present embodiment described above, the toilet lid 3 and the toilet seat 4 are closed when a predetermined time elapses using the toilet lid timer 16 and the toilet seat timer 17, but other sensors are added. Then, for example, it is detected whether or not a person is sitting in front of the toilet seat 4 by detecting whether or not a person is sitting in front of the toilet bowl 2 even when the toilet seat 4 is opened. There is also a method of closing if there are no people. If the toilet 2 is used, the toilet 2 is usually washed, and there is a method of detecting the washing operation and closing the toilet lid 3 and the toilet seat 4.
