A motion activated bidet washing apparatus light emitting diode (LED) display system includes a bidet washing apparatus equipped with a control unit, a passive infrared (PIR) sensor supported by the apparatus or control unit, wherein the control unit regulates a flow of water through the apparatus and the LED display system; a light-dependent resistor (LDR) supported by the apparatus or control unit; one or more LEDs arranged around the apparatus or control unit; an electrical power source; and a printed circuit board in electrical communication with the electrical power source, the PIR sensor, the LDR, and the one or more LEDs, wherein a combination of the MR sensor and the LDR allows the LED display system to turn on only when in a dark environment and when someone comes nearby.

A trip lever assembly for a toilet includes a body and an infrared sensor. The body is configured to be mechanically coupled to a flush valve assembly of the toilet. The infrared sensor is coupled to the body, and is configured to be electrically coupled to the flush valve assembly. The body is configured to be manually actuated to control the flush valve assembly. The infrared sensor is a time-of-flight sensor configured to detect the distance of an object in a detection region of the infrared sensor to control the flush valve assembly.

A unisex urinal structure contains: a body including a horizontal receptacle and a vertical urinal portion. The horizontal receptacle includes an arcuate rib, a draining portion, at least one water spray element, a dropping segment, and a pipe. The pipe has a first straight section, an S-shaped section, and a second straight section. The vertical urinal portion includes a collection tank and at least one water spray element of the vertical urinal portion. A guide conduit is fixed on a predetermined position thereof in the vertical urinal portion and a predetermined position in the horizontal receptacle to communicate with the at least one water spray element of the vertical urinal portion and the at least one water spray element of the horizontal receptacle. A sensory switch is fixed on a predetermined position of the body.

There is provided a flush water tank apparatus capable of returning to a state where next toilet flush operation can be started in a short time while opening a discharge valve using a water supply pressure. A flush water tank apparatus (4) includes a reservoir tank (10), a discharge valve (12), a discharge valve hydraulic drive portion (14) configured to drive the discharge valve using a water supply pressure, and a discharge/vacuum break valve device (30) provided on an upstream side of the discharge valve hydraulic drive portion and configured to supply the water supplied from the upstream side to the discharge valve hydraulic drive portion on a downstream side. The discharge valve hydraulic drive portion includes a cylinder (14a) into which the water from the discharge/vacuum break valve device flows, and a piston (14b) configured to be moved by a pressure of the water flowing into the cylinder to move the discharge valve. The discharge/vacuum break valve device includes a valve body that operates to discharge the water flowing backward from the discharge valve hydraulic drive portion while opening the upstream side to an atmosphere when the supply of the water from the upstream side is stopped.

A system of household appliances is configured to provide services according to user identity. The system includes a first appliance, a server or other network device, and a second appliance. The first appliance is configured to collect sensor data associated with an identity of a user. The server or other network device is configured to receive the sensor data from the first appliance and analyze the sensor data to determine the identity of the user. The second appliance is configured to provide a device function to the user based on the identity determined from the sensor data collected by the first appliance.

A system for monitoring flush valves includes a plurality of flush valves arranged in at least one restroom, each flush valve including a communication device configured to transmit flush valve data, and at least one controller arranged in a first flush valve and in communication with each other flush valve. The at least one controller is configured to determine a static pressure within the first flush valve, detect a second pressure within the first flush valve, determine that the second pressure is less than the static pressure, in response to determining that the second pressure is less than the static pressure, compare the second pressure with at least one other pressure associated with at least one other flush valve, and determine that the first flush valve is in need of servicing or replacement based on comparing the second pressure with the at least one other pressure.

A flush valve has a relief valve including a stationary relief valve housing and an axially-translatable valve element. The axially-translatable valve element has an axial end that can be selectively translated to unseal an upper opening in a relief passageway through the stationary relief valve housing in order to permit fluid flow therethrough in order to initiate a flush cycle by the lifting of a diaphragm assembly. The axially-translatable valve element may include lead screw-like features which can be used to axially drive the axially-translatable valve element relative to the stationary relief valve housing to open or close the relief valve.

A flush toilet includes: a toilet main body; a rim which is provided on an upper portion of a toilet bowl of the toilet main body and which flows a flush water into the toilet bowl; and a water level detection sensor which is provided inside the rim.

A method for controlling water spouting of a toilet includes: a target region where a foreign object exists is determined from multiple predetermined regions in the toilet; a target water spout corresponding to the target region is determined according to pre-stored correspondences between the multiple regions in the toilet and water spouts for flushing the multiple regions; and the target water spout is controlled to spout water.

A flush toilet includes a bowl, a tank coupled to the bowl, a flush valve positioned within the tank, and a flush device configured to initiate a flush cycle. The automatic toilet further comprises an electronic sensing assembly having a sensing member positioned on the bowl for detecting an overflow condition of the bowl, an overflow device operably coupled to the flush device, and a controller in electronic communication with the electronic sensing assembly and the overflow device for controlling the flush device in response to a condition of the toilet.
