A wireless water control system includes a water heater connected to a water supply, a water line sensor device connected to a water line in fluid communication with the water heater, a wireless flow control valve connected to the water line, and at least one outlet faucet in fluid communication with the water line. The components are in wireless communication via a shared wireless network such as a Bluetooth connection. The control circuit receives user information including one or more parameters from an external device via the wireless network. The control circuit wirelessly activates the outlet faucet via a command sent through the wireless network, such that the outlet faucet emits water in a manner corresponding to the received user information. The outlet faucet also includes a speaker and microphone which facilitates voice activation. The speaker can emit music, text-to-speech for written information received from the internet, and other sounds.

The present invention intends to provide a drinking water circulation device (2) for cold water consumption, which is compactly accommodable in a building, universally and easily connectable to different cooling devices, easy to operate and, in addition, little failure-prone and easy to install. This drinking water circulation device (2) comprises a heat exchanger for cooling the drinking water, a return connection (24) for feeding drinking water returned from a circulation pipe into the drinking water circulation device (2), a supply connection (26) for discharging the cooled drinking water from the drinking water circulation device (2), a drinking water circulation pump (10) provided between the return connection (24) and the supply connection (26), a buffer tank (4) for a cooling medium (22), a cooling medium pump (22) provided in a cooling medium flow path between the buffer tank (4) and the heat exchanger (6), a control device (12) for controlling the cooling medium pump (8) and a supply temperature sensor (56), which is associated with the supply and is data-connected to the control device (12).

The present invention discloses a hot water dispenser comprising a water tank, an expansion chamber, and a Venturi module. The expansion chamber comprises a top shell, a bottom shell connected to the top shell, and a flexible bladder. Wherein, the water tank is connected to a dedicated faucet, the Venturi module is connected to a water source through the faucet, so when the dedicated faucet is closed, the expansion chamber then immediately creates suction and removes a part of the hot water from the water tank and into the expansion chamber to avoid hot water residue dripping from the faucet. In addition, when the water in the water tank is heated to its boiling point, a part of the hot water will be sucked into the expansion chamber to reduce the pressure in the water tank and prevent the hot water from being ejected out of the faucet due to vapour.

A sink system is provided. The sink system includes a sink basin and a discharge conduit coupled to the sink basin, which is positioned to expel fluid into the sink basin via an outlet thereof. The flow of fluid through the discharge conduit may be activated via a motion sensor or switch coupled directly to the basin or a spacer ring positioned between the basin and the countertop. Controls for adjusting the temperature and/or flow rate of fluid through the discharge conduit may also be coupled to the basin or a spacer ring positioned between the basin and the countertop, or alternatively, to a surface of the countertop. Methods of making and using sink systems are also provided.

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

Provided is a mixer faucet that can suppress the occurrence of water leakage. A mixer faucet includes: a fixed valve body including a hot water supply hole, a cold water supply hole, and a drain hole; a movable valve body that includes a flow path forming recess and is configured to slide on the fixed valve body; and a handle configured to control the movable valve body. The fixed valve body includes a collection groove that is not connected to either the hot water supply hole or the cold water supply hole and is connected only to the drain hole. The collection groove can capture water leaking from the hot water supply hole, the cold water supply hole, or the drain hole. The captured water can flow into the drain hole through the collection groove.

A water mixing system attached to an existing plumbing system supplying ambient temperature water and providing temperature regulated water to a user. The water mixing system includes an insulated water tank, a heat pump connected to the insulated water tank with a heat rejecting radiator inside the insulated water tank and a heat absorbing radiator outside the insulated water tank, a temperature detector in the insulated water tank, and one outlet of the insulated water tank connected to a first inlet of a first dispensing water tank. Having a second inlet to receive the ambient temperature water from the existing plumbing system and at least one dispensing outlet, the first dispensing water tank provides mixed water of a desirable temperature from heated water from the insulated water tank and the ambient temperature water via control of the valves attached to the first inlet and the second inlet.
