A method for controlling a refrigerating device of a water dispenser. The method includes: S1, controlling a refrigerating module to cool water in a cold water tank; S2, when the temperature of the water in the cold water tank is reduced to a first preset temperature, stopping the refrigerating module at the first preset time; S3, controlling the refrigerating module to work again to continue cooling the water in the cold water tank; S4, when the temperature of the water in the cold water tank is reduced to an n.sup.th preset temperature, stopping the refrigerating module at the n.sup.th preset time; and S5, determining whether the temperature of the water in the cold water tank reaches a target temperature, and if not, repeating steps S3 and S4 after reaching a predefined number. Through multi-stage refrigeration, an ultra-low temperature refrigeration is achieved.

A liquid dispensing device includes a needle. The needle is adapted to penetrate a container without tearing out a portion of the container. The portion of the container is near a point of penetration on the container. The liquid dispensing device includes a motion control system. The motion control system is configured to rotate the needle while the needle penetrates the container.

A refrigerator having a carbonated water production module integrally provided with a carbon dioxide gas cylinder having carbon dioxide gas stored therein and a carbonated water tank to mix purified water with the carbon dioxide gas to produce carbonated water. The carbonated water production module is mounted to the rear surface of the door, and thus it may be cooled by cool air in the refrigeration compartment and be easy to access, and thereby repair and replacement thereof is facilitated. The dispenser includes a carbonated water discharge channel into which carbonated water from the carbonated water tank is discharged, and a purified water discharge channel into which purified water from the water tank is discharged. Since the purified water discharge channel does not pass through the carbonated water tank, a user is allowed to selectively dispense purified water or carbonated water anytime.

The embodiments disclose a method of an intelligent beverage kiosk system for customized beverage preparation including preparing customized beverage selections for meeting a consumer's taste, recording a member's customized beverage selection for reducing member beverage delivery wait time, creating a member smart beverage cup with layered component compartment modules for downloading and ordering a member customized beverage selection, ordering member customized beverage selections using a wireless intelligent beverage kiosk application for reducing ordering time for a customized beverage selection and adjusting intelligent beverage kiosk window height for facilitating beverage delivery for drive-thru vehicle pickup.

An automated consumable dispenser with a precision method for delivering consumable ingredients in specific proportions to a container up to a specified volume. This method involves the use of a system of sensors and a micro-microprocessor, which detects, digitizes and develops a three dimensional rendering of the container, calculates the container volume and dispenses specific amounts of consumable ingredients. A user is able to pick the level in the vessel to which the consumable ingredients should be dispensed and displays the selected desired level. The embodiments described include an automated dispenser capable of dispensing beverages and food items, either separately or together.

A refrigerated consumable-liquid dispenser. A consumable-liquid container is carried in a covered refrigerated housing that includes a heat exchanger for maintaining consumable-liquid at a predetermined temperature which may be pre-selected depending on the type of consumable-liquid being carried. A dispensing tube provides a conduit for the consumable-liquid. To dispense the consumable-liquid, a pressure differential is produced in response to the user command, whereby the pressure on the liquid in the container is greater than the pressure at a dispensing port. User command may be achieved without physical contact with the consumable-liquid dispenser, for sanitary and health related considerations.

The present invention discloses a beverage dispenser, including: an inlet connected to a water source; an outlet for dispensing the water to a user vessel; at least one filter element having an input and an output for filtered water; a pump for pumping water to the input of the filter element; a flow sensor connected between the inlet and the outlet, wherein the flow sensor determines the actual flow rate of the water; at least one water preparation element connected between the output for outputting filtered water and the outlet and adapted to prepare the water for drinking by a human, wherein the water preparation element comprises a water preparation rate input by which the water preparation rate of the water preparation element can be controlled; and a controller connected to the water preparation rate input of the water preparation element and the flow sensor, wherein the controller controls the water preparation rate of the water preparation element by a signal to the water preparation rate input such that the water preparation rate is proportional to the actual flow rate.

A beverage dispensing device prepares and dispenses a beverage. The dispensing device includes a housing which has a beverage unit with a liquid inlet and a beverage outlet. The beverage unit has a receiving means for at least one container containing a unit dose of concentrated beverage ingredient to be dispensed, and an ingredient discharge. The beverage unit has a liquid line. The liquid line first section extends from the base liquid inlet to receiving means liquid inlet to guide base liquid into the unit dose of beverage ingredient through the beverage discharge into the liquid line second section that extends from the ingredient discharge to the beverage outlet. A mixing chamber is defined in the liquid line. Temperature regulating means are provided in the mixing chamber or in that the mixing chamber comprises an inlet for pressurized fluid for expanding said fluid in said mixing chamber.

Disclosed herein is a refrigerator capable of producing carbonated water and a control method thereof. The refrigerator includes a carbonated water tank to store carbonated water a carbon dioxide gas supply valve to open/close a carbon dioxide gas flow path to guide carbon dioxide gas from a carbon dioxide gas cylinder to the carbonated water tank, and a carbonated water tank pressure sensor to detect an internal pressure of the carbonated water tank.

The present disclosure provides a drinking liquid cooling system comprising: a first cooler configured to cool drinking liquid; a second cooler configured to allow the drinking liquid from the first cooler to have a pre-defined temperature; and a drinking liquid guider configured to guide the drinking liquid via the first cooler and, then, via the second cooler and, then, to allow the drinking liquid to be discharged.
