  • Patent number: 10597857
    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. The bowl includes a flush region and a non-flush region. The controller executes a pre-mist mode and an after-mist mode. The pre-mist mode includes automatically controlling the spray device, spraying the mist onto the flush region and the non-flush region, and forming a water droplet or a water film by causing the mist to accumulate in the flush region and the non-flush region. The after-mist mode includes automatically controlling the spray device to rinse away the water droplet or the water film formed in the non-flush region in the pre-mist mode by increasing a volume of the water droplet or the water film.

  • Patent number: 10590639
    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.

  • Patent number: 10584469
    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.

  • Patent number: 10570599
    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.

  • Patent number: 10563388
    Abstract: According to one embodiment, a toilet device includes a flush toilet, a toilet seat, a sterilizer, a sprayer, and a controller. The flush toilet includes a bowl and a rim. The sterilizer generates sterilizing water. The sprayer sprays a mist of the sterilizing water onto the bowl, the rim, and the toilet seat. The controller controls the sprayer to cause an average wetting amount per unit area at the toilet seat and the amount per unit area at an upper surface of the rim each to be smaller than the amount per unit area at the bowl and smaller than the amount per unit area at an inner wall surface of the rim for one time of performing a mist mode to spray the mist of the sterilizing water onto the bowl, the rim, and the toilet seat.
