Abstract

According to one embodiment, a toilet seat device includes a toilet seat, a sterilizer, a sprayer, a blower, and a controller. The sterilizer generates sterilizing water. The sprayer sprays a mist of the sterilizing water. The blower generates a rising air stream. The controller controls the sprayer to execute first and second processes and cause a total amount of the mist sprayed in the first process to be less than that in the second process. The first process and the second process are executed at different timing. The first process includes controlling the blower to generate a first rising air stream capable of lifting the mist toward the toilet seat. The second process includes the blower not generating the first rising air stream and not lifting the mist toward the toilet seat.

Claims (31)

1. A toilet seat device mounted on a flush toilet, the toilet seat device comprising:

a toilet seat where a user is seated;

a sterilizer generating sterilizing water;

a sprayer disposed lower than the toilet seat in a state in which the toilet seat device is mounted on the flush toilet, the sprayer spraying a mist of the sterilizing water into the flush toilet;

a blower generating a rising air stream by blowing air into the flush toilet; and

a controller controlling the sterilizer, the sprayer, and the blower,

the controller controlling the sprayer to execute a first process and a second process and cause a total amount of the mist of the sterilizing water sprayed in the first process to be less than a total amount of the mist of the sterilizing water sprayed in the second process, the first process and the second process being executed at different timing in a state in which the controller controls the sprayer to spray the mist of the sterilizing water into the flush toilet, the first process including controlling the blower to generate a first rising air stream capable of lifting the mist of the sterilizing water toward the toilet seat, the second process including the blower not generating the first rising air stream and not lifting the mist of the sterilizing water toward the toilet seat.

2. The toilet seat device according to claim 1 , wherein the controller stops the blower in the second process.

3. The toilet seat device according to claim 1 , wherein

the controller controls the blower to generate a second rising air stream, and

a flow velocity of the second rising air stream is lower than a flow velocity of the first rising air stream in the second process.

4. The toilet seat device according to claim 1 , wherein the sprayer sprays the mist of the sterilizing water in a radial configuration when viewed in the top view in the second process.

5. The toilet seat device according to claim 1 , wherein the controller sets a time of the execution of the first process to be shorter than a time of the execution of the second process.

6. The toilet seat device according to claim 1 , wherein the controller controls the sprayer to cause a particle size of the mist of the sterilizing water sprayed in the execution of the second process to be larger than a particle size of the mist of the sterilizing water sprayed in the execution of the first process.

7. The toilet seat device according to claim 1 , wherein the controller performs the execution of the second process after the execution of the first process.

8. A toilet device, comprising:

a flush toilet including a bowl and a rim, the bowl receiving excrement, an upper edge part being formed of the rim;

a toilet seat mounted on the flush toilet, the toilet seat being where a user is seated;

a sterilizer generating sterilizing water;

a sprayer disposed lower than the toilet seat in a state in which the toilet seat is mounted on the flush toilet, the sprayer spraying a mist of the sterilizing water into the flush toilet;

a blower generating a rising air stream by blowing air into the flush toilet; and

a controller controlling the sterilizer, the sprayer, and the blower,

the controller controlling the sprayer to execute a first process and a second process and cause a total amount of the mist of the sterilizing water sprayed in the first process to be less than a total amount of the mist of the sterilizing water sprayed in the second process, the first process and the second process being executed at different timing in a state in which the controller controls the sprayer to spray the mist of the sterilizing water into the flush toilet, the first process including controlling the blower to generate a first rising air stream capable of lifting the mist of the sterilizing water toward the toilet seat, the second process including the blower not generating the first rising air stream and not lifting the mist of the sterilizing water toward the toilet seat.

9. The toilet device according to claim 8 , wherein the controller stops the blower in the second process.

10. The toilet device according to claim 8 , wherein

the controller controls the blower to generate a second rising air stream, and

a flow velocity of the second rising air stream is lower than a flow velocity of the first rising air stream in the second process.

11. The toilet device according to claim 8 , wherein the sprayer sprays the mist of the sterilizing water in a radial configuration when viewed in the top view in the second process.

12. The toilet seat device according to claim 8 , wherein the controller sets a time of the execution of the first process to be shorter than a time of the execution of the second process.

13. The toilet device according to claim 8 , wherein the controller controls the sprayer to cause a particle size of the mist of the sterilizing water sprayed in the execution of the second process to be larger than a particle size of the mist of the sterilizing water sprayed in the execution of the first process.

14. The toilet device according to claim 8 , wherein the controller performs the execution of the second process after the execution of the first process.
