Some specific examples of control patterns for the spray device 47 by the control device 49 will be described. When the control device 49 receives the operation signal of the mist switch of the first operation section 21, the control device 49 causes the spray device 47 to spray manual mist.

When the control device 49 determines that the state has changed from not detecting the user to detecting the user based on the detection information of the human body detection unit 31, it causes the spray device 47 to spray the premist. The area where the pre-mist is sprayed is the area excluding the top surface of the toilet seat 11.

When the control device 49 determines that the state in which the user is detected has changed from the state in which the user is not detected based on the detection information of the human body detection unit 31, the control device 49 causes the spray device 47 to spray aftermist. . The spray area of the aftermist may cover a wide range of the toilet device R, and may include, for example, the upper surface of the toilet seat 11.

The control device 49 causes the spray device 47 to spray regular mist at a predetermined timing. The timing of periodic misting may be, for example, a predetermined day or time, or when a predetermined period of time has elapsed after the last mist of manual misting, pre-mist, after-mist, or periodic mist. Good too. The spray areas of the periodic mist may be the second area and the third area. This suppresses drying of the second region and the third region, and prevents water scale and dirt from sticking to the second region and the third region.

The control device 49 places the spray device 47 in either the first state or the second state under predetermined conditions. In the first state, the spray device 47 is stopped. The first state includes a state in which the spray device 47 in operation stops immediately, a state in which the spray device 47 in operation stops for a time shorter than the predetermined time T, and a state in which the spray device 47 in stoppage continues to stop. include. In the second state, mist is sprayed onto a second predetermined area below the first predetermined area. The upper end of the second predetermined area is lower than the upper end of the first predetermined area. The second predetermined region may be, for example, a region below the waste receiving surface 14 of the toilet bowl portion 13, or a region of the toilet bowl portion 13 close to the water surface. The means for changing the mist spray area from the first predetermined area to the second predetermined area include, for example, reducing the amount of liquid to be sprayed, changing the direction of the airflow of the blower, reducing the force of the spray, or The particle size of the mist may be changed, the direction of the mist ejected from the nozzle 47A may be changed, the nozzles 47A may be provided in the upper and lower parts of the toilet device R, and the mist may be ejected only from the lower nozzle 47A.

The predetermined condition is when a person approaches the toilet main body 10. Specifically, the predetermined conditions include the following conditions 1, 2, 3, 4, 5, 6, and 7. Condition 1 is when the user approaches the toilet main body 10 before sitting on the toilet seat 11. Condition 2 is when the user is present near the toilet main body 10 when the toilet lid 12 is in the upright state. Condition 3 is when the user sits on the toilet seat 11. Condition 4 is when either the toilet seat 11 or the toilet lid 12 changes from a collapsed state to an upright state. Condition 5 is when the operation unit 20 is operated.
