A flush toilet includes a toilet main body and a tank device for supplying flush water to the toilet main body, where the tank device includes a storage tank provided behind the toilet main body and above a floor surface, the storage tank includes a large tank section and a small tank section and has an asymmetrical shape in a front-back or left-right direction, the large tank section being a large-capacity side of the storage tank that is divided into two at a center in the left-right direction when seen in the front-back direction, the small tank section being a small-capacity side of the storage tank that is divided into two at the center in the left-right direction, and the storage tank or the toilet main body includes a deformation-preventing supporting member for preventing deformation of the storage tank by supporting the storage tank.

Flush toilet

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.

Urinal

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.

Toilet device and toilet seat device

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.

Toilet seat device and toilet device

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.

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.

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.

To provide a urinal apparatus, including: a water supplying device configured to supply water to a bowl section of a urinal; a trap section provided in a lower part of the bowl section and configured so that urine and water flow into the trap section; and a water sprinkling device configured to sprinkle water droplets to a region inside the bowl section, the region being located between the trap section and position of a nose of a user facing the bowl section, wherein the timing of sprinkling the water droplets by the water sprinkling device being different from timing of supplying water by the water supplying device.

Urinal with separate water supplying and water spraying devices

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.

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 M; a first equipment flushing mode Min which a portion of flush water flushes the upstream side of a connecting portion; and a second equipment flushing mode Min which a portion of flush water flushes the upstream side of the connecting portion. At least one of either the first mode Mor the second mode M, 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.
