Abstract

According to one embodiment, a toilet device includes a flush toilet, a toilet seat, a spray device, a detecting sensor, and a controller. The flush toilet includes a bowl, a rim upper surface, and a water discharge port. The bowl includes a flush region and a non-flush region. The controller executes a pre-mist mode by automatically controlling the spray device to spray the mist into the bowl. In the pre-mist mode, the controller controls the spray device to cause the mist to directly wet a front end part of the non-flush region and to cause an average wetting amount per unit area of the mist directly wetting an upper region of the front end part to be less than an average wetting amount per unit area directly wetting a lower region of the front end part.

First claim

What is claimed is:

1. A toilet device, comprising:
a flush toilet including a bowl, a rim upper surface, and a water discharge port, the bowl receiving excrement, the rim upper surface being positioned on the bowl, the water discharge port discharging flushing water into the bowl to discharge the excrement from the bowl, the bowl including a flush region and a non-flush region, the flush region being where the flushing water passes, the non-flush region being positioned higher than the flush region and lower than the rim upper surface;
a toilet seat mounted on the flush toilet, the toilet seat being where a user is seated;
a spray device positioned on a rearward side of the bowl, the spray device spraying a mist into the bowl;
a detecting sensor detecting the user; and
a controller controlling the spray device based on detection information of the detecting sensor,
the controller executing a pre-mist mode by automatically controlling the spray device to spray the mist into the bowl when a state in which the detecting sensor does not detect the user changes to a state in which the detecting sensor detects the user,
in the pre-mist mode, the controller controlling the spray device to cause the mist to directly wet a front end part of the non-flush region and to cause an average wetting amount per unit area of the mist directly wetting an upper region of the front end part to be less than an average wetting amount per unit area of the mist directly wetting a lower region of the front end part.

2. The toilet device according to claim 1 , wherein
the upper region has a tilted surface tilted downward toward an outside of the bowl, and
the lower region has a tilted surface tilted downward toward an inside of the bowl.

3. The toilet device according to claim 1 , wherein the controller controls a particle size of the mist sprayed from the spray device, and in the pre-mist mode, the controller controls a particle size of the mist directly wetting the lower region to be larger than a particle size of the mist directly wetting the upper region.

4. A toilet seat device mounted on a flush toilet, the flush toilet including a bowl, a rim upper surface, and a water discharge port, the bowl receiving excrement, the rim upper surface being positioned on the bowl, the water discharge port discharging flushing water into the bowl to discharge the excrement from the bowl, the bowl including a flush region and a non-flush region, the flush region being where the flushing water passes, the non-flush region being positioned higher than the flush region and lower than the rim upper surface, the toilet seat device comprising:
a toilet seat where a user is seated;
a spray device positioned on a rearward side of the bowl, the spray device spraying a mist into the bowl;
a detecting sensor detecting the user; and
a controller controlling the spray device based on detection information of the detecting sensor,
the controller executing a pre-mist mode by automatically controlling the spray device to spray the mist into the bowl when a state in which the detecting sensor does not detect the user changes to a state in which the detecting sensor detects the user,
in the pre-mist mode, the controller controlling the spray device to cause the mist to directly wet a front end part of the non-flush region and cause an average wetting amount per unit area of the mist directly wetting an upper region of the front end part to be less than an average wetting amount per unit area of the mist directly wetting a lower region of the front end part.

5. The toilet seat device according to claim 4 , wherein
the upper region has a tilted surface tilted downward toward an outside of the bowl, and
the lower region has a tilted surface tilted downward toward an inside of the bowl.

6. The toilet seat device according to claim 4 , wherein the controller controls a particle size of the mist sprayed from the spray device, and in the pre-mist mode, the controller controls a particle size of the mist directly wetting the lower region to be larger than a particle size of the mist directly wetting the upper region.
