The present invention provides a refrigerator door body with a water dispenser and a water intake passage arranged thereon. A water intake assembly of the water dispenser comprising: a water inlet component, a water outlet component, a valve core and a water intake handle. The water intake handle has one end pivotally connected to the refrigerator door body and is provided with a through hole. When the water intake assembly is in a closed status, there is no acting force between the water outlet component and the through hole in the water intake handle; and the other end of the water intake handle is pressed such that one end, pivotally connected to the refrigerator door body, of the water intake handle is rotated. The water outlet component is displaced axially relative to the water inlet component and thus the water intake assembly is in an open status.

A removable liquid transport assembly configured to be readily installed in and removed from a liquid dispenser to permit the liquid dispenser to be readily sanitized. The removable liquid transport assembly preferably includes a liquid manifold, a valve assembly and a pump head. The removable liquid transport assembly is configured such that liquid can flow in a first direction through the removable liquid transport assembly to permit a liquid to be dispensed from a liquid dispenser and liquid can flow in a second direction back to a liquid storage container to prevent damage to one or more components of the liquid dispenser.

A liquid dispenser includes a first lifting cover, a second lifting cover, a lifting motor, a gear module, and a dispenser nozzle. The first lifting cover includes a lifting gear extending in a vertical direction. The gear module includes a gear bracket coupled to the second lifting cover and a gear. The gear is rotated along the lifting gear by the operation of the lifting motor, and the second lifting cover is relatively moved with respect to the first lifting cover in the vertical direction.

A system can coordinate a smart bottled water delivery service, which comprises one or more processors of a network-accessible server and one or more memory resources storing program instructions. The system determines whether a trigger event has occurred based on a first data and a second data, which are related to a total number of bottled water currently hold by a customer, and a total number of the bottled water used up by the customer, respectively. After the trigger event has occurred, the system sends a replenishment message to a customer's device. When the system receives data associated with the replenishment order, it determines a pool of candidate delivery drivers that can satisfy a criterion. Then the system provides an instruction to a device of a selected delivery driver to dispatch the selected delivery driver with a particular vehicle to a designated collection, storing and distribution device.

Various beverage preparation systems and methods are disclosed. The beverage preparation system can include a dispensing unit configured to receive beverage, such as a shot of espresso, from a beverage preparation machine. The dispensing unit can include a dispensing unit with a first end and a second end. The dispensing unit can be rotatable between an upright position and an inverted position. The dispensing unit can be configured to receive the beverage through the second end when the dispensing unit is in the upright position, and can be configured to receive cleansing fluid through the second end when the dispensing unit is in the inverted position. In some embodiments, when the dispensing unit is in an intermediate position between the upright and inverted positions, the dispensing unit is configured to dispense the beverage out of the first end and into a cup or other vessel.

A system and method for dispensing sparkling and other pressurized beverages from a container. Sparkling wine and other beverages may be dispensed without removing a cork or other closure. One or more needles may be inserted through the closure and sparkling beverage dispensed through the one or more needles. The one or more needles may be inserted at an angle to the vertical or axis of the bottle opening in which the closure is positioned, e.g., to avoid contact with a metal retainer on the closure. Dispensed beverage may be directed to a pressurized reservoir to help maintain or recover carbonation prior to dispensing.

A water purifier that includes: a filter unit that is configured to purify water; a cooling unit that is configured to cool water purified by the filter unit using cooling water; a water discharge unit that is configured to discharge water cooled by the cooling unit; a cold water flow path that couples the cooling unit to the water discharge unit and through which water cooled by the cooling unit passes; a cold water discharge valve that is coupled to a first side of the cooling unit and that is configured to control water flow inside the cold water flow path; and a check fitting unit that is coupled to a first side of the water discharge unit and that is configured to block pressure change inside the cold water flow path is disclosed.

A water storage device and a refrigerator, the water storage device comprising: a housing having a water inlet end and a water outlet end, and a water distribution plate. The water distribution plate divides a water storage cavity into a water inlet cavity and a water outlet cavity; a gap for allowing water to flow through is provided between the outer edge of the water distribution plate and the inner wall of the housing; when the water distribution plate moves from the water inlet end towards the water outlet end, water entering the water inlet cavity from the water inlet end will not mix with cold water in the water outlet cavity.

A removable liquid transport assembly configured to be readily installed in and removed from a liquid dispenser to permit the liquid dispenser to be readily sanitized. The removable liquid transport assembly preferably includes a liquid manifold, a valve assembly and a pump head. The removable liquid transport assembly is configured such that liquid can flow in a first direction through the removable liquid transport assembly to permit a liquid to be dispensed from a liquid dispenser and liquid can flow in a second direction back to a liquid storage container to prevent damage to one or more components of the liquid dispenser.

Apparatus, and methods for constructing and implementing beverage containment and dispensing systems are provided herein. An example apparatus includes a thermally-insulated container, an adjustable pressure regulator positioned within the thermally-insulated container, a stopper component, and one or more tubes connected to the adjustable pressure regulator and to the stopper component. The example apparatus also includes an external housing within which the thermally-insulated container is contained, and a user-controllable faucet component affixed to the external housing and connected to the adjustable pressure regulator through the external housing and thermally-insulated container via at least one conduit.
