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 into a flush toilet. The blower generates a rising air stream. The controller controls the sprayer to simultaneously generate first and second mists in a state in which the blower generates a first rising air stream. The first mist has a particle size liftable toward the toilet seat by the first rising air stream. The second mist is generated to have a particle size larger than that of the first mist and not to be lifted toward the toilet seat by the first rising air stream. The sprayer causes a total amount of the first mist to be less than that of the second mist.

Claims (27)

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 simultaneously generate a first mist of the sterilizing water and a second mist of the sterilizing water in a state in which the controller causes the blower to generate a first rising air stream inside the flush toilet, the first mist having a particle size liftable toward the toilet seat by the first rising air stream, the second mist being generated to have a particle size larger than the particle size of the first mist and not to be lifted toward the toilet seat by the first rising air stream, the sprayer causing a total amount of the first mist to be less than a total amount of the second mist.

2. The toilet seat device according to claim 1 , wherein the sprayer sprays the sterilizing water to cause the first mist to be formed higher than the second mist.

3. The toilet seat device according to claim 2 , wherein the sprayer sprays the first mist obliquely upward with respect to a horizontal plane.

4. The toilet seat device according to claim 3 , wherein the sprayer sprays the second mist parallel or obliquely downward with respect to the horizontal plane.

5. The toilet seat device according to claim 1 , wherein the sprayer sprays the first mist and the second mist each in radial configurations when viewed in the top view.

6. The toilet seat device according to claim 1 , further comprising a washing nozzle discharging water toward a private part of the user seated on the toilet seat,

the washing nozzle being disposed between the sprayer and the blower in a width direction of the washing nozzle.

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

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 simultaneously generate a first mist of the sterilizing water and a second mist of the sterilizing water in a state in which the controller causes the blower to generate a first rising air stream inside the flush toilet, the first mist having a particle size liftable toward the toilet seat by the first rising air stream, the second mist being generated to have a particle size larger than the particle size of the first mist and not to be lifted toward the toilet seat by the first rising air stream, the sprayer causing a total amount of the first mist to be less than a total amount of the second mist.

8. The toilet device according to claim 7 , wherein the sprayer sprays the sterilizing water to cause the first mist to be formed higher than the second mist.

9. The toilet device according to claim 8 , wherein the sprayer sprays the first mist obliquely upward with respect to a horizontal plane.

10. The toilet device according to claim 9 , wherein the sprayer sprays the second mist parallel or obliquely downward with respect to the horizontal plane.

11. The toilet device according to claim 8 , wherein the sprayer sprays the first mist and the second mist each in radial configurations when viewed in the top view.

12. The toilet device according to claim 8 , further comprising a washing nozzle discharging water toward a private part of the user seated on the toilet seat,

the washing nozzle being disposed between the sprayer and the blower in a width direction of the washing nozzle.
