A ceramic toilet pan having a raised rear portion to which a hinge tube may be accurately located and fixed in position for example by adhesive using a jig despite variations in pan body size due to ceramic firing, a water pump and air pump being provided for flushing the toilet pan when a seat and lid are in a closed position. The seat and lid are rotationally mounted to the pan by a horizontal hinge pin located in the hinge tube and a latch member is provided for latching the lid and seat closed. A cistern is also provided having an overflow weir.

A brace includes two or more spacers connected together using an interlocking mechanism, such as a press fit, an interference fit, a friction fit, a snap fastener, a projection-and-recess coupling system or a stud-and-tube coupling system, to provide a desired combined length. The brace may further include a U-shaped clip for attachment to a toilet tank or may use a plate with an adhesive layer for attachment to an object. The brace may also include a threaded stud and a nut coupled to a spacer for adjusting the combined length of the brace.

A toilet system with a toilet base including a toilet bowl and a shroud for covering a plumbing riser located at a rear end of the toilet base that provides ligature-resistance for institutional applications. The shroud has a mating feature that joins with a corresponding feature at a rear portion of the toilet base to prevent formation of a gap between the base and a front of shroud in at least at a top side of the area of contact between the shroud and the back of the toilet base. The mating feature can be provided by forming a rectangular cross-section at the rear of the toilet base and providing a matching aperture through the shroud. A toilet seat, which may be bonded or bolted to toilet base has an outer edge that is chamfered to prevent ligature formation around a portion of toilet seat.

A toilet apparatus for providing intelligent bidet dispensing is disclosed. Dynamic dispensing according to a bidet wand position, type of substance dispensed, user preferences, user gender, and user identification is disclosed. Cleansers, surfactants, moisturizers, medicines, deodorants, and fragrances are dispensed through a bidet wand to a user and are stored reservoirs which are contained in a tank area of the toilet. In other embodiments, reporting of levels of reservoir substances is automated.

The instant invention provides an improved toilet 10 that promotes ease and convenience of cleaning and promotes simplicity without clutter, by providing easy access to implements housed by the toilet. An example provides an access port 40 formed through a toilet wall, such as a cover 25 that allows passage of an implement, i.e., a toilet brush 55, stored within the toilet.

A toilet tanks can be stabilized by an adjustable brace that is adjustably securable to and passes through a wall of the tank, and which can extend beyond the tank to engage a nearby structural wall surface. The amount of extension can be adjusted to match the distance from the tank wall to the structural wall in a particular situation.

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.

A siphon valve assembly, the assembly comprising a tubular core; a head coupled to and surrounding a top of the core; and a fluid spray initiator coupled to the head; wherein a lower end of the head defines a siphon valve inlet, a lower end of the tubular core defines a siphon valve outlet, an upper end of the tubular core comprises a weir, and the spray initiator is configured to discharge a fluid into the core to induce a siphon flow of a surrounding fluid through the siphon valve inlet, over the weir, and out the siphon valve outlet.
