Abstract: A urinal capable of constraining the occurrence of uric scale in a discharge horizontal branch pipe even if flush water volume has been reduced by water conservation is disclosed. A urinal includes a control unit with a main flush mode M0; a first equipment flushing mode M1 in which a portion of flush water flushes the upstream side of a connecting portion; and a second equipment flushing mode M2 in which a portion of flush water flushes the upstream side of the connecting portion. At least one of either the first mode M1 or the second mode M2, the value of the discharge volume or the discharge instantaneous flow volume discharged is set to be equal to or greater than the value of the discharge volume or the discharge instantaneous flow volume in the main flush mode.

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.

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.

Abstract: A urinal capable of suppressing the flow speed differential between the flow speed of flush water flowing into the front side of an ascending pipe and the flow speed of flush water flowing into the back side thereof, and of suppressing the occurrence of stagnation in the flow of flush water, and of suppressing the occurrence of uric scale. The urinal having a discharge trap including a horizontal pipe; a top portion of horizontal pipe is formed by a return flow path-forming portion at the bottom end of the shared wall; and a resistance portion for slowing the flow speed of flush water flowing in the vicinity of this bottom portion is formed at the bottom portion of the horizontal pipe.

Abstract: A urinal for receiving and discharging urine having a bowl portion having a bowl surface for receiving urine; a spouting device disposed on a top portion of the bowl portion for spouting flush water onto the bowl surface; and a discharge trap portion, communicating with a discharge port disposed on a bottom portion of the bowl portion, for discharging flush water and forming a water seal on a downstream side of the bowl portion. The discharge trap includes a descending conduit, a horizontal conduit, and an ascending conduit, and a cross section perpendicular to a discharging direction of either the horizontal conduit or the ascending conduit on the discharge trap portion is formed so that an inner side of the urinal from a center of the cross section has a smaller cross sectional area than an outer side of the urinal from the center of the cross section.

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.
