A toilet device includes a toilet body that has a toilet bowl, a toilet seat that is attached to the toilet body and has a bowl facing surface facing an inner surface of the toilet bowl in the up-and-down direction and provided on a back surface thereof, a discharge part that can discharge a cleaning liquid so that the cleaning liquid runs along a bowl facing surface, and a guide that can guide a part of the cleaning liquid so that the cleaning liquid runs along an inner peripheral side portion of the bowl facing surface.

Disclosed herein is an inactivation apparatus for inactivating microorganisms and/or viruses, comprising: an ultraviolet light irradiation unit configured to irradiate a surface or a space in a facility or a vehicle that a human or an animal is present with light including ultraviolet light having a wavelength that inactivates the microorganisms and/or viruses; and a controller unit configured to control irradiation and non-irradiation of the light by the ultraviolet light irradiation unit. The ultraviolet light included in the light emitted from the ultraviolet light irradiation unit is light having a wavelength range between 190 nm to 235 nm. The controller unit controls the ultraviolet light irradiation unit to alternately repeat a light-emitting operation and a non-light-emitting operation of the light based on the wavelength of the ultraviolet light included in the light irradiated from the ultraviolet light irradiation unit.

To collect excretion information indicating a content of excrement in a toilet bowl without having to ask a user of a toilet and prevent flushing of a foreign body other than the excrement, even when the foreign body is present in the toilet bowl.

The information processing system (1) includes an acquisition unit (1a) that acquires excretion information on the basis of imaging data captured by an image capture apparatus installed in such a way as to include, in an image capture range, an excretion range of excrement in a toilet bowl of a toilet, a generation unit (1b) that generates presentation information on the basis of the excretion information, an output unit (1c) that outputs the presentation information, and a washing control unit (1d) that controls a washing function of the toilet bowl. The acquisition unit (1a) acquires information that indicates whether a foreign body being an object other than feces and urine is included in the imaging data as a subject excluding the toilet bowl and washing liquid for the toilet bowl, as at least a part of the excretion information. When information including the foreign body is acquired, the washing control unit (1d) outputs a stop command for stopping the washing function to the toilet bowl side, and the generation unit (1b) generates alert information as at least a part of the presentation information.

An rinsing seat for a rimless toilet is disclosed. In one embodiment, the rinsing seat includes a large annular cavity for the purpose of storing and dispensing rinse water. In another embodiment, the rinsing seat includes a smaller annular cavity for the purpose of dispensing rinse water from a pressurized line. Outlet nozzles arranged about the circumference of the rinsing seat and designed to dispense rinse water at varying angles relative to the rinsing seat are disclosed. Rinsing seat supports, hinge assemblies, and seat sensors which offer additional functionality to the rinsing seat are also disclosed and claimed herein.

A lavatory accessory positioning device may include a support bracket having an aperture which may be used to couple the device to a toilet. A support pole may be coupled to the support bracket, and the support pole may be movable between an extended position and a retracted position. A support platform may be coupled to the support pole. A hanger bracket may be coupled to the support platform, and the hanger bracket may be movable between a horizontal position and a vertical position. The hanger bracket may have a distal accessory holder which may be configured to removably couple a lavatory accessory to the device. When a lavatory accessory is coupled to the distal accessory holder and the support pole is in the extended position and the hanger bracket is in the horizontal position, the lavatory accessory may be positioned above a portion of the toilet to which the device is coupled.

The present disclosure provides a descaling apparatus of an electronic toilet bidet, the descaling apparatus comprising: a descaling liquid storage tank comprising a descaling liquid chamber configured to house descaling liquid, wherein a pressure element is disposed and movable in the descaling liquid chamber, wherein the descaling liquid chamber comprises a descaling liquid outlet, wherein the descaling liquid storage tank further comprises a main body liquid outlet fixedly connected to and in communication with a bidet liquid inlet of the electronic toilet bidet, and wherein the main body liquid outlet is configured to be controlled to connect or disconnect the descaling liquid outlet. The descaling apparatus according to the present disclosure may supply the descaling liquid automatically and continuously to the internal pipes of the electronic toilet bidet for several times after the descaling liquid is added at one time.

Systems and methods of cleaning toilets are described; the system includes a structural frame, a foldable arm extendible from the structural frame and a rotatable brush, accommodated while being folded within and retracted into the foldable arm, at an idle state, while protruded from the foldable arm and being sprawl, during the operation of a cleansing cycle.

A fluid removal system includes an operative sub-system, such as an ultraviolet (UV) light sanitizing system, that is configured to operate according to an operative cycle, such as a sanitizing cycle, and is configured to output an activation signal during the operative cycle. An actuator is operatively coupled to the operative sub-system and moveably connected to a fluid removal conduit. The fluid removal conduit is closed when the actuator is in a closed position, and opened when the actuator is in an open position. The actuator moves into the open position in response to the operative sub-system outputting the activation signal. Fluid, such as ozone, within a confined space is drawn into the fluid removal conduit when the actuator is in the open position and exhausted through an exhaust port.

A self-cleaning floor assembly is configured to form or be positioned on a floor of an enclosed space. The self-cleaning floor assembly includes a moveable floor including a moveable floor panel, an actuation system that is operatively coupled to the floor panel, and a cleaning system proximate to at least a portion of the moveable floor. The actuation system is configured to move at least a portion of the floor panel into and through the cleaning system during a cleaning cycle. The cleaning system is configured to clean the portion(s) of the floor panel during the cleaning cycle.
