The invention provides a carbonation tank assembly for admixing a gas and a potable liquid used in preparation of drinks. The assembly includes a tank body with an interior that can be easily accessed for cleaning and repair purposes by removing upper and lower end plates securely and sealing fitted by gaskets to the upper and lower ends of the tank. The interior is connected to a liquid source for supplying liquid, a gas source for carbonating the liquid, and drawing means for dispensing carbonated liquid from the interior of the tank.

A dispenser of nitrogen gas infused cold brew beverages includes a product container, a nitrogenator, a mixing unit, and a dispensing unit. The nitrogenator receives water from a water source and nitrogen gas from a nitrogen gas source and infuses the nitrogen gas into the water to produce nitrogen gas infused water. The mixing unit receives product from a product container and nitrogen gas infused water from the nitrogenator. The mixing unit combines the product and the nitrogen gas infused water to induce a mixing thereof that creates a nitrogen gas infused beverage. The dispensing unit receives nitrogen gas infused beverage from the mixing unit. The dispensing unit chills the nitrogen gas infused beverage to produce a nitrogen gas infused cold brew beverage for dispensing therefrom.

The present invention is directed towards a liquid drink dispensing apparatus. The apparatus comprises a gas generating component and a liquid drink dispensing component. The generated gas is supplied to the liquid drink dispensing component which infuses the generated gas into a liquid drink prior to dispensing the gas-infused liquid drink. The advantage of using a gas generating component is that the gas can be created on-site and no bottled gas needs to be used. This obviates the problems associated with purchasing, storing, using and replacing gas cylinders.

A refrigerator having a carbonated water production device, according to one concept of the present invention, comprises: a pressure regulator for adjusting and emitting the pressure of carbon dioxide emitted from a carbon dioxide cylinder; a solenoid switch valve for controlling the supply of the carbon dioxide discharged from the pressure regulator to a carbonated water tank; a connection channel for connecting the pressure regulator and the solenoid switch valve; and a relief valve arranged in the connection channel so as to discharge the carbon dioxide of the connection channel to the atmosphere if the pressure of the carbon dioxide of the connection channel is greater than a predetermined pressure limit. Thus, the pressure of the carbon dioxide of the connection channel is capable of being maintained at a predetermined pressure limit or less, and solenoid malfunction can be prevented so as to improve reliability and stability of a system.

A beverage machine system that includes: an insulated potable liquid storage tank having an interior volume; a liquid carbonator spaced within the interior volume of the insulated potable liquid storage tank and submerged therein; a high pressure potable liquid pump configured to pump potable liquid from the interior volume of the insulated potable liquid storage tank through a potable liquid conduit to a spray nozzle within an interior volume of the liquid carbonator; and a cooling coil positioned in a spaced apart relationship but wound around the carbonator such that the cooling coil does not physically touch an exterior surface of the carbonator submersed within the chilled potable liquid and the space between the cooling coil and the carbonator is at least substantially free of any other structure other than periodic frozen potable liquid adjacent the cooling coil.

A carbonation tower for containers of household appliances, more specifically for appliances for the automatic preparation of instant drinks, which has been developed to provide more optimized operation and use and efficient than those achieved with the known similar. Said carbonation tower including a substantially elongated body included of at least one pipe provided with at least two holes and said pipe secured to a base including at least a nozzle, said cooperating base further including a lid of a lower compartment; said lid further including at least one toroidal contoured rib cooperating with at least one lower nozzle of the container, and wherein the water and the carbon dioxide are sucked by the upper edge of the pipe and/or the holes and expelled in a path orthogonal to the suction axis through the at least one nozzle.

This disclosure is related to a refrigerator and a method of controlling the same. The refrigerator includes a dispenser passage, a water supplier for supplying sterilizing water or rinsing water to the dispenser passage, a drain for draining the sterilizing water or the rinsing water that is supplied to the dispenser passage, and a controller for performing a sterilization cycle and controlling the water supplier and the drain to perform a rinsing cycle after completing the sterilization cycle, wherein the sterilization cycle is a cycle of keeping the sterilizing water in the dispenser passage and then draining the sterilizing water, and the rinsing cycle is a cycle of supplying the rinsing water to the dispenser passage and draining the rinsing water therefrom.

A nano-bubble water generating apparatus containing an application gas includes a motor, a pump integrated with the motor for supplying liquid, typically water, from an inlet pipe under a predetermined pressure through a supplying pipe to a pressure tank, a nano-bubble water generating tube mounted at the water entrance of a pressure tank, an electronic control portion, a pressure adjuster including an outer air inflowing portion to introduce an outer air or a specific gas supplied thereinto to control a pressure in the pressure tank, uniformly and a pressure adjusting portion airtightly coupled on the upper portion of the outer air inflowing portion to adjust an amount of outer air or specific gas to be supplied, and a nano-bubble water expanding tube for expanding and shattering nano-bubble water through an outlet pipe from the pressure tank, so that the size of the nano-bubble water is better micronized.

Systems, methods and cartridges for carbonating or otherwise dissolving gas in a precursor liquid, such as water, to form a beverage. A gas source can be provided in a cartridge which is used to generate gas that is dissolved into the precursor liquid. A beverage medium, such as a powdered drink mix or liquid syrup, may be provided in the same, or a separate cartridge as the gas source and mixed with the precursor liquid to form a beverage. The use of one or more cartridges for the gas source and/or beverage medium may make for an easy to use and mess-free system for making sparkling beverages, e.g., in the consumer's home.

A beverage dispenser (1) includes a cold water tank (20) for storing cold water (50), a carbonation tank (30) disposed with at least a bottom portion thereof being submerged in the cold water (50) in the cold water thank (20), the carbonation tank being configured to generate carbonated water (60) by adding carbon dioxide gas to the cold water (50) supplied from the cold water tank (20), a carbonated water outlet passage (35) for taking out the carbonated water (60) from the carbonation tank (30) and a heater (41) for heating the cold water (50) in the cold water tank (20). In order to sterilize the above beverage dispenser (1), the heater (41) is caused to heat the cold water (50) in the cold water tank (20) to a temperature higher than a predetermined temperature, thereby to sterilize the cold water tank (20) and the carbonation tank (30). After the carbonated water (60) in the carbonation tank (30) is taken out via the carbonated water outlet passage (35), hot/warm water (70) in the cold water tank (20) is cooled.
