A two-way or four-way water faucet dispenses near-boiling water on demand but has a safety interlock. A control valve assembly is attached to the faucet. The interlock uses two disks pressed into contact, each having a single projecting sector. One disk is fixed to the valve body. The other disk, fixed to the handle, slides against the first. The disks must be pulled apart by sliding the handle while it is being turned to superimpose the sectors and turn the control valve, connecting the faucet to the vented near-boiling water supply. A reed switch inside the fixed sector is activated by a magnet inside the rotatable sector and activates a near-boiling water pump.

Dispensing of hot water having an adjustable temperature by way of a water outlet fitting that can be installed on a sink. This is achieved by a continuous flow heater and a measured value sensor arranged in a water inlet of the water outlet fitting as the hot water heater. The measured value sensor detects a measurement variable with regard to water flowing through the continuous flow heater (10). The water dispensing device has a control unit, which is designed to regulate a flow rate through the continuous flow heater as a function of measured values of the measured value sensor in order to adjust the temperature of the hot water.

Kitchen appliances usually include devices such as a water system, a cooker, a kitchen hood (range hood), an oven, a refrigerator, a microwave, a dishwasher and other devices. The devices are mostly operated independent from each other. Unlike those devices the drinkable tap water-based liquid supply system according to the present invention comprises a few devices controlled by an advanced control system according to the invention for providing connectivity and system management. The system is designed to provide comfort, convenience and energy saving. The water-based liquid supply system according to the present invention provides a variety of water-based liquids, dispatched with the desired properties from a countertop faucet.

Water tap (2) or water valve assembly is provided which has biometric recognition means (20) provided on or associated with the same. The biometric recognition means (20) are arranged such that operation of the water tap (2) or water valve assembly and/or operation of one or more functions of the water tap (2) or water valve assembly takes place only upon recognition or a positive match of one or more biometric features of a user.

The present invention provides an injection-molded faucet body and a method for manufacturing the same. The faucet body includes a plastic housing constituting the outer layer thereof and a plastic inner core constituting the inner layer thereof. When the plastic inner core, among the same, is injection-molded using double plastic injection molding, a valve spool mounting groove, a cold water supply opening, a warm water supply opening, a cold water supply tank, a warm water supply tank, and a water discharge tank are formed. In addition, sealing cover plates are installed in the cold water supply tank, the warm water supply tank, and the water discharge tank such that a cold water supply cavity, a warm water supply cavity, and a water discharge cavity are formed therein, respectively. The plastic housing is formed by performing secondary injection coating with regard to the plastic inner core.

Tap provided with a tap outflow having a first channel and a second channel and a jet aerator having a jet aerator housing which forms a downstream end of the tap outflow. The jet aerator is further provided with a jet breaker having a jet breaker wall with liquid passage openings, at least one wire mesh layer which is included downstream of the jet breaker wall in the jet aerator housing, an aeration chamber which is situated between the jet breaker and the at least one wire mesh layer, and an air supply of which an entrance opens into the environment and of which an exit opens into the aeration chamber. The tap outflow is further provided with a coupling assembly which is situated upstream of the jet breaker wall in the jet aerator housing and which forms a liquid-tight connection between the first conduit and the jet breaker wall, such that liquid from the first channel is kept separate from liquid from the second channel upstream of the jet breaker wall.

A tap includes a tap outflow having a first channel and a second channel and a jet aerator in a housing. The jet aerator includes a jet breaker having a wall with liquid passage openings, a wire mesh layer included downstream of the jet breaker wall, an aeration chamber situated between the jet breaker and the wire mesh layer, and an air supply having an entrance that opens into the environment and an exit that opens into the aeration chamber. The tap outflow includes a coupling assembly situated upstream of the jet breaker wall. The outflow forms a liquid-tight connection between the first conduit and the jet breaker wall, such that liquid from the first channel is kept separate from liquid from the second channel upstream of the jet breaker wall.

A fluid heating system including a heating chamber that receives fluid and heats the fluid to provide heated fluid, a dispensing device that dispenses the heated fluid, the dispensing device encompassing the heating chamber, a thermostatic control device that regulates a power supply to the heating chamber, an energy recovery device that harvests mechanical energy provided by a flow of the heated fluid from the heating chamber to the dispensing device and generates electrical energy to power the thermostatic control device, a pressure regulating valve, wherein in a closed position, passage for the heated fluid is prevented between the heating chamber and the drain when a pressure in the heating chamber is below a predetermined pressure threshold and passage for the heated fluid is provided between the heating chamber and the drain when the pressure in the heating chamber is above the predetermined pressure threshold.

A method of operating a water tap, in particular a hot water tap, including a dispensing step in which water is dispensed from the water tap. Initiation of the dispensing step requires several preceding steps, including an actuation of a first actuating element and an actuation of a second actuating element. Within an actuation step, the actuation of a first actuating element is detected by a control unit. The actuation step also includes an unlocking step, in which, upon detection of the actuation of the first actuating element, an unlocking time window is started by the control unit. The actuation step also includes an activating step in which the actuation of the second actuating element activates a dispensing switch. The dispensing step is only initiated in case that the activating step is triggered within the unlocking time window.

A water tap body (10) has a housing (110) having an exterior wall (112). At least one valve (120) is contained within the housing (110). The valve (120) has least one inlet (121,122) and at least one outlet (123) and is operable to control the flow of water from the inlet (121,122) to the outlet (123). The valve (120) is spaced from the exterior wall (112) of the housing (110).
