A water inlet pipe connects a water supply to a faucet. A water flow control valve in the water inlet pipe regulates the flow of water through the water inlet pipe from the water supply to the faucet. A drip tray located beneath the faucet captures water overflow. A conduit connects the drip tray a storage container such that water in the drip tray drains into the storage container. A water level sensor associated with the storage container generates a overflow signal when the water level in the storage container reaches a pre-set level. The water flow control valve automatically prevents water flow through the water inlet pipe to the faucet in response to the overflow signal. A visible display and a sound generator are also energized in response to the alarm signal.

Provided is a liquid dispensing device. The liquid dispensing device includes an internal member coupled to a sink and a nozzle. A liquid processing module is installed separately from the dispenser and may include components to generate, for example, a heated liquid, a cooled liquid, or a liquid having a sterilizing agent. Piping coupling the liquid processing module to the nozzle may extend through the internal member, and one or more components may couple the internal member under the sink. One or more valves may be positioned on the piping to direct fluid from the liquid processing module to the nozzle or to discharge fluid.

An embedded system controls an electric fluid valve, and the embedded system is connected to and receives overlooking images from an overlooking camera. It processes the images using a sequence labeling unit to tell if a fluid container is ready to receive and operates the valve accordingly.

A beer dispenser having a nozzle for positioning above a container and dispensing beer into the container. The dispenser includes at least one imaging device for generating at least one image of the dispensed beer, and a processor. The processor determines a measured foam height and a liquid upper surface from the at least one image of the dispensed beer, and adjusts a distance between the nozzle and the liquid upper surface as the beer is dispensed to control the measured foam height.

A dispense control system for a dispensing assembly of a refrigerator appliance and a method for operating the same are provided. The dispensing assembly defines a base plane for receiving a container. A dispense control system includes an emitter for directing a beam of energy toward the container and the base plane and a receiver for detecting a projection of the beam of energy in an image plane of the receiver. The dispense control system may be configured to obtain a measured displacement of the projection when the container is positioned on the base plane, and an actual height of the container or a liquid level within the container may be determined from the measured displacement of the projection.

A beverage dispenser includes an inlet for drawing a liquid from a source and an outlet for outputting a beverage to a portable user vessel. A demineralization device demineralizes the liquid from the source and has an input and an output. The input of the demineralization device is coupled with the inlet. A beverage preparation device has an input and an output. The input of the beverage preparation device is coupled with the output of the demineralization device and the output of the beverage preparation device is coupled with the outlet. The beverage preparation device, the outlet, all active components and all passive components downstream of the demineralization device contacting the beverage are made of a biological inert material, particularly a biological inert metal, on any surface contacting the water. All couplings of the beverage dispenser are manufactured such that stagnation even of small quantities of beverage is avoided.

A liquid dispenser comprise a nozzle comprising an inlet in fluid communication with an outlet to form a flow path, a thermistor in fluid communication with the inlet, an actuator rod comprising a gasket rod tip viton, at least one centering pin to center the actuator rod in at least a portion of the flow path, a flowmeter in fluid communication with the inlet, a double acting pneumatic cylinder comprising a first pneumatic inlet and a second pneumatic inlet operatively connected to the actuator rod, and a switch lever operatively coupled to a micro switch, wherein the nozzle opens when gas enters the first pneumatic inlet when the switch lever is activated by pressing on the micro switch and closes when gas enters the second pneumatic inlet when the switch lever is deactivated. Portable and non-portable liquid dispensing systems comprising the liquid dispenser are also described.

A beverage maker may include a fermenter having a space therein to make a beverage; a fluid tank configured to contain fluid; a fluid supply pump connected with the fluid tank; a flow rate detection sensor disposed in a channel connected with the fluid supply pump to detect a flow velocity or a flow rate of fluid which is discharged through the channel by the fluid supply pump; and a controller configured to perform a plurality of operations related to making of a beverage or cleaning of an inside of the beverage maker. The controller may be configured to when an operation requiring a supply of fluid is ongoing from among the plurality of operations, turn on the fluid supply pump to discharge fluid contained in the fluid tank; detect a lack of fluid in the fluid tank based on a first flow velocity or a first flow rate detected by the flow rate detection sensor; and generate a fluid replenishment request for the fluid tank based on a result of detecting.

A water purifier according to an embodiment of the present invention may include a housing accommodating components for generating cold water and/or hot water; a water cock which protrudes from a front surface of the housing, the water cock being configured to discharge the cold water or the hot water; a control panel which is provided so as to input a command for discharging the cold water or the hot water; a sterilization module which is detachably mounted on the water cock, the sterilization module being configured to emit ultraviolet rays for sterilizing the inside of the water cock; and a fastening part which is formed on the water cock and the sterilization module, respectively, so that the sterilization module can be attached to and detached from the water cock.
