Patent attributes
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.
