Disclosed herein is a washing and drying nozzle device for a sanitary toilet seat cover. The washing and drying nozzle device includes: a toilet seat-cover device including a support frame configured such that a cover member and a seat are rotatably coupled thereto and a sensor unit configured to detect the presence of a foreign material is mounted on the front portion thereof; a drying nozzle coupled to the support frame, and configured to dry a user's washed body by spraying air toward the user's body and to radiate far-infrared rays toward the user's body; a washing nozzle coupled to the support frame, and configured to spray water toward the user's body; a nozzle driving means installed in the support frame, and configured to slide and rotate the drying nozzle and the washing nozzle; and a control unit configured to control the driving of the nozzle driving means.

A sterilization device for sanitary equipment, applicable to a toilet, the sterilization device including: a controller; a disinfectant sprayer, provided with a storage container and sprayer, the disinfectant sprayer in electric connection with the controller; and a disinfection lamp, in electric connection with the controller. The present invention controls the disinfectant sprayer or disinfection lamp through the controller to disinfect the sanitary equipment of the toilet, for example, to disinfect stool, bathtub or sink by spraying alcohol or emitting ultraviolet light. Furthermore, the controller may be in connection with the timer; when a predetermined time set by the timer has expired, the controller controls the opening or closing of the disinfectant sprayer, or the on and off of the disinfection lamp, thereby improving use safety and convenience.

Among others, the present invention provides toilet seat assemblies for cleaning, disinfecting, and/or sanitizing toilet seat, each including a base configured to be secured to the top surface of the toilet bowl; a toilet seat attached to the base and movable between an open position and a closed position; and a cover attached to the base and movable between an open position and a closed position. The toilet seat assembly may include a liquid discharge and disperse means, which further includes one or more liquid discharge apertures for discharging a liquid, particularly with an atomizer for spraying the mist, and one or more gas discharge apertures for facilitating dispersal of the liquid, thereby enabling the liquid to contact, clean, disinfect and/or sanitize the toilet seat.

Systems and methods for containing fluid splash include using a fluid flow spaced from a vessel and/or fluid surface to effectively trap materials from a fluid stream flowing through the fluid flow. The fluid flow creates a spray envelope in connection with the fluid surface and/or vessel and substantially prevents droplets of the fluid stream from exiting the vessel. The fluid flow is created by allowing a supply fluid to flow through a nozzle oriented to cast a spray pattern into the vessel and/or into contact with the fluid surface. The fluid flow may be selectively activated and deactivated and/or be automatically (e.g., light or motion) activated and deactivated.

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.

A clean water system includes at least one water tank including water, a plurality of water consuming devices coupled to the water tank, and an automatic dispenser. The automatic dispenser is configured to automatically discharge a predetermined amount of a cleaning compound into water of at least on water tank, wherein the cleaning compound is distributed to the plurality of water consuming devices.

A toilet seat cover is configured to fit over a corresponding toilet seat, forming an air tight seal around the toilet seat at a lower edge of the toilet seat cover when the toilet seat cover is in a lowered position. The toilet seat cover provides a seat channel in the underside of the toilet seat cover in which the seat resides when the toilet seat cover is lowered. There is a gap between the toilet seat and the underside of the toilet seat cover in the seat channel to allow air to flow between the seat and the underside of the toilet seat cover. The toilet seat cover includes a fluid channel and a plurality of nozzles along the fluid channel which spray the toilet seat with a cleaning or sanitizing fluid when the toilet seat cover is in the lowered position. After stopping the spraying of sanitizing fluid, the toilet is flushed using suction, lowering the air pressure under the toilet seat cover. Holes in the toilet seat cover into the seat channel direct the flow of air over the surface of the toilet seat to dry the toilet seat.

The fluid flow may be selectively activated and deactivated and/or be automatically (e.g., light or motion) activated and deactivated.

A toilet assembly with a self-cleaning rim system is provided. The toilet assembly includes a toilet tank for storing water used by the toilet assembly. The toilet assembly includes a flush valve disposed within the toilet tank that opens and closes to deliver the stored water in the toilet tank. The toilet assembly includes a toilet bowl comprising a rim having a hollow section and a top surface forming an area suitable for water flow. The toilet assembly includes a rinse channel including a rinse channel inlet for receiving water from the toilet tank, the rinse channel configured to deliver the water for cleaning the top surface of the rim with each activation of the flush valve.

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.
