The present invention provides an electronic plumbing fixture fitting including a preset feature.

A connector for an electronic faucet including a light source. The connector includes a socket and is configured to distinguish between an electrically conductive plug and an electrically non-conductive plug for controlling activation of the light source.

The present disclosure relates to a metered dispense input device that wirelessly communicates with a wireless control module of an electronic faucet to allow wireless control of the faucet such that selected volumes of water can be dispensed. The present disclosure further relates to a metered dispense input device that is integrated into an electronic faucet to allow the dispensing of selected volumes of water.

Various embodiments of a reverse thermostat for use in restricting hot water in a plumbing system from being delivered to cold water fixtures are disclosed.

A faucet having a series of nozzles positioned longitudinally along the length of a spray arm to provide a robust and thorough delivery of water for the washing of produce. A thermometer may be integrated into the faucet to provide water temperature readings from various locations along the faucet. A valve allows for the nozzles to be turned on or off as desired by a user. The nozzles of the faucet provide a robust spray over the area under faucet, thereby improving the rinsing of produce. The thermometer allows a user to ensure that produce is washed at the correct temperature to open stomata and remove any trapped bacteria or other harmful items.

Apparatus is provided to electronically operate the hot water and/or cold water supply lines connected to any manual faucet, which can be utilized for any home or business's kitchen and/or bathroom. The electronic water distribution center is a universal device that can connect to any faucet system or water spout to control the water temperature and pressure electronically, hence still allow the users preferred faucet's hot and cold manual controls to move the temperature and pressure up or down manually for the water which is outputted from the spout. The said apparatus has one or two main units in total, which is a central control system and/or a main mcu system. The wired central control system, which can be the entire apparatus, transmits a wired signal to actuate one or more electronic water valves or the wireless central controller or a mobile device send a wireless signal, by way of (Bluetooth, WIFI, ZIGBEE, or any radio controlled signal), to the main mcu system, which in this instance the central controller and the main mcu unit is a two piece apparatus, to actuate one or more electronic water valve. One electronic water valve controls the hot water and the second electronic water valve control the cold water. Both electronic water valves used in unison creates a precise warm water temperature. The said apparatus can electronically control the pressure output for any home or business's kitchen and/or bathroom, faucet electronically by pressing the hot, cold, or warm temperature switch push buttons up or down or can output water from the apparatus, via a touch-less and/or wireless means, by utilizing the central controller systems on-board motion sensor and/or the external stand-alone motion sensor circuit.

A plumbing system for a shower or the like includes a mixing valve operable for delivering a water flow of adjustable temperature from a water source to a dispensing device downstream from the mixing valve. The system further includes a diverter valve between the mixing valve and the dispensing device, and operable to divert a selectively variable portion of the water from the mixing valve back to the water source. A thermochromic thermal indicator, downstream from the mixing valve, may advantageously provide a visible indication of the water flow having achieved a predetermined temperature. The thermal indicator may be a thermochromic PVC conduit, or it may be a fitting having an inlet, an outlet, a thermochromic PVC element therebetween, and a barrier located between the inlet and the outlet so as to define a flow path that includes an interior surface of the thermochromic element.

A water delivery system includes a mixing valve operable for delivering a water flow of adjustable temperature from a water source to a dispensing device downstream from the mixing valve; a thermochromic thermal indicator, fluidly coupled between the mixing valve and the dispensing device, that provides a visible indication of the water flow having achieved a predetermined temperature; and a diverter valve, fluidly coupled between the mixing valve and the dispensing device, and operable to direct the water flow selectively either to the dispensing device or back to the water source. The thermal indicator may be a thermochromic PVC conduit, or it may be a fitting having an inlet, an outlet, a thermochromic PVC element therebetween, and a barrier located between the inlet and the outlet so as to define a flow path that includes an interior surface of the thermochromic element.

A sanitary device has a programmable electronic control unit that acts on a metering and mixer valve unit. The electronic control unit has a program memory suitable for the retrievable storage of multiple different water dispensing programs and a central data processing unit that acts on at least one actuator that actuates the metering and mixer valve unit. A user interface has a display that has a central display region and a peripheral display region annularly surrounding the central display region, a rotatable setting ring around the display and at least three buttons around the setting ring. The buttons of the user interface comprise a program selection button, an output button and a temperature button. Actuating a button results in the present setting value of the button function in question being displayed in the central display region of the display.

A water discharge structure and a sensor-operated water discharge device are disclosed. The water discharge structure includes a valve core seat having independent cold water, hot water and sensor-operated mixed water flow channels. An accommodating chamber is disposed inside the sensor-operated mixed water flow channel for accommodating a solenoid valve that controls opening and closing of the sensor-operated mixed water flow channel. The valve core seat has a cold water outlet, a hot water outlet, a sensor-operated mixed water inlet and a mechanically-operated mixed water inlet that are located on a same end face of the valve core seat. It is convenient to assemble the valve core seat and the valve core of the sensor-operated water discharge device. The overall assembly of the sensor-operated water discharge device can be realized when it leaves the factory, and the installation operation can be simplified for the user.
