A water purifier includes: a cooling water tank that keeps cooling water; a stirring member that is provided in the cooling water tank to stir cooling water; a cold water pipe that is provided in the cooling water tank; an evaporator that is provided in the cooling water tank; and a separator on which the evaporator is provided and that is provided over the cold water pipe to divide the internal space of the cooling water tank into a first space and a second space, in which the separator has: a bottom that is horizontally formed and has a center hole through which the stirring member is inserted; a first extension that extends upward from the edge of the center hole; and a plurality of separation walls that extend upward from the top of the bottom and are arranged at a predetermined distance from each other around the center hole.

An induction heater and a water dispenser having an induction heater are provided. The induction heater may include a hot water tank assembly formed by coupling edges of a first cover and a second cover to each other and provided with an inner space to heat liquid. The first cover may be configured to have a flat plate shape and to be heated by a working coil. The second cover may include a base configured to face the first cover and separated from the first cover, and a welding portion formed by welding with the first cover and provided on a protruding surface that protrudes from the base toward the first cover.

A water purifier according to an embodiment comprises: a cooling water tank storing cooling water; a partition member mounted inside the cooling water tank and partitioning an inner space of the cooling water tank into an upper space and a lower space; a cold water pipe which is accommodated in the lower space and through which edible water flows; an evaporator which is accommodated in the upper space and through which a refrigerant flows; and an agitator penetrating the partition member and disposed in the lower space so as to stir the cooling water. The partition member comprises: a bottom portion on which the evaporator is mounted, the bottom portion having a plurality of cooling water through-holes formed therein; and an outer wall portion extending upward along an edge of the bottom portion to form an evaporator accommodating portion. The outer wall portion is spaced apart from an inner wall of the cooling water tank so as to prevent ice formed in the evaporator accommodating portion from being in contact with the inner wall of the cooling water tank.

A dispenser system for providing variable carbonation can include a carbonated water source in communication with a carbonated water valve for controlling flow of carbonated water through the dispenser system; a still water source in communication with a still water valve for controlling flow of still water through the dispenser system; a nozzle in fluid communication with the carbonated water source and still water source; a processing device adapted to modulate the carbonated water and still water valves within a modulate cycle to achieve a ratio of carbonated to non-carbonated water; and a pour mechanism adapted to provide an input to the processing device to dispense the beverage.

A system and method for dispensing fluids is introduced. A preferred embodiment comprises a sealed tank, a bag containing fluid inside the sealed tank, an outlet for dispensing the liquid in the bag, and a pressure generating device to create pressure in the sealed tank.

An adapter having a female coupling configured to receive and establish a friction seal with a male coupling of an external device for inserting or extracting a liquid to or from a container, by applying a load to the male coupling after inserting it into the female coupling, the load being provided by the weight of a portion of the external device, the adapter being configured for insertion in a mouth of the container and secured therein using a stretchable membrane that fits snugly around the mouth of the container for obtaining a tight seal, the stretchable membrane having tabs for a user to grasp.

A carbonated drink dispensing system includes a carbonation tank, a CO.sub.2 cylinder configured to deliver CO.sub.2 to the carbonation tank at a pressure of between 50 psi and 60 psi, a low-pressure pump configured to pump water into the carbonation tank, and a level sensor configured to determine when the water in the carbonation tank has reached a pre-determined level. The low-pressure pump is configured to stop pumping water when the level sensor determines that the water in the carbonation tank has reached the pre-determined level. The low-pressure pump starts pumping water again after a time delay.

A liquid dispenser is provided. The liquid dispenser may include a water tank to store water, a cooling module provided in the water tank to circulate cooling water to cool the water to make cold water, a drain valve that connects to the water tank and protrudes from the water tank to discharge the cooling water in the water tank, and a foam insulator that covers an outer circumferential surface of the water tank and contacts the drain valve to prevent the drain valve from being exposed to air.

A cooling system for rapidly cooling a beverage comprises a cooling channel configured to convey a beverage from upstream to downstream and a nozzle. The cooling channel includes an inner peripheral surface and the nozzle sprays the beverage on the inner peripheral surface such that the beverage is conveyed by gravity along the inner peripheral surface. The beverage cools as the beverage is conveyed by gravity along the inner peripheral surface such that the beverage is cooled by condensation and convection. The nozzle is further configured to reduce the pressure of the beverage such that the beverage cools due to expansion and reduction of pressure. The cooling system can also include a cooling media circulation system, a cooling media refrigeration system, and a post-chill coil.

A beverage dispenser includes a gas infusion device that receives a base fluid and a gas and dispenses a gas infused liquid, a ratio pump that receives the gas infused liquid and a concentrate from a concentrate source and dispenses a predetermined ratio of the gas infused liquid and the concentrate, and a mixing chamber that mixes the predetermined ratio of the gas infused liquid and the concentrate to form a reconstituted beverage. An insulated enclosure has an interior space in which the ratio pump and the mixing chamber are positioned. A cooling heat exchanger is positioned in the insulated enclosure, and a first refrigeration system circulates a cooling media through the cooling heat exchanger to thereby cool the interior space to a suitable temperature such that the gas infused liquid and the concentrate dispensed from the ratio pump and the mixing chamber are cooled to the suitable temperature.
