Liquid dispensing systems which sanitize the liquid and liquid-contacting parts of a liquid dispensing system using ozonation, by periodically flushing the system with ozonated gas or liquid. Also disclosed and claimed are an apparatus and method for controlling temperature variations between the liquid in holding (e.g., cold and/or hot) tanks and the liquid as it is dispensed, which may be used with an Insta-Boil feature.

A cooling device including a water tank case, an evaporator at least a portion of which is accommodated in the water tank case to exchange heat with cooling water stored inside the water tank case, a water tank case insulating portion foam-molded to surround an outer surface of the water tank case, a water tank cover having at least one component disposed thereon and disposed on the upper side of the water tank case, a water tank cover insulating portion foam-molded to form a water tank insulating portion seamlessly integrated with the water tank case insulating portion and surrounding an outer surface of the water tank cover, and a sealing member around the at least one component disposed on the water tank cover to prevent a gap leading to the water tank case from being formed.

The present invention is directed to a beverage dispenser connector (1) comprising a dispenser body (2) defining a cavity (3) with an opening (4) to be open at a side of the dispenser body (2), a connection section (6) to attached the dispenser body (2) with the open cavity (3) over a delivery section (102) of a container (100) to close the cavity (3) with the delivery section (102), an inlet (7) to deliver a fluid into the cavity (3), an outlet (8) to discharge the fluid out of the cavity (3), and a needle (9) with a piercing tip (90), the needle (9) being associated with the dispenser body (2) so as to be moveable between a retracted position in which the piercing tip (90) is positioned within the cavity (3) and an extended position in which the piercing tip (90) protrudes out of the cavity (3) via the opening (4). The invention is further directed to a beverage production device comprising the beverage dispenser connector (1), a liquid supply (201), a gas supply (202), and a discharge section (203). Further, the present invention is directed to a method for beverage production with the beverage production device (200).

A water heating system is provided. The water heating system includes an inlet connectable to a supply of untreated water, supply and return lines connectable to a point-of-use water treatment system, and an output for dispensing a supply of treated and optionally heated water. An internal heating element is adapted to heat the treated water to one of a plurality of pre-selected temperature settings. Temperature control can be achieved by cycling the power applied to the heating element and/or controlling the flow rate of treated water through the heating element. The water heating system includes additional improvements in electrical compatibility, energy consumption, and remote failure detection.

The present invention is directed to a beverage mixing device (2) comprising a mixing body (3) defining a mixing chamber (30), at least one or a plurality of fluid inlets (4, 5, 6) for supplying a fluid (L, W, A, S) into the mixing chamber (30), a discharge opening (7) to discharge a liquid (P) from the mixing chamber (30), a sealing element (8) being moveably provided between a closed position for closing the discharge opening (7) and an open position for releasing the discharge opening (7) to allow a liquid (P) in the mixing chamber (30) be discharged via the discharge opening (7), and an evacuation outlet (9) for evacuating the mixing chamber (30) by a fluid (G) be introduced into the mixing chamber (30) via the at least one or the plurality of fluid inlets (4, 5, 6) when the discharge opening (7) is closed by the sealing element (8). The present invention is further directed to a beverage preparation device (1) comprising the beverage mixing device (2), a liquid supply (20), at least one or a plurality of product supplies (40), a gas supply (50), and a drainage (60). Also, the present invention is directed to a method for preparing a beverage product using the beverage preparation device according to the invention.

A drinking water dispenser includes a cold water tank and a hot water tank. A cold water outlet pipeline connects the cold water tank to a cold water outlet. A hot water outlet pipeline connects the hot water tank to a hot water outlet. A first pipeline connects an inlet pipeline to the cold water tank. A circulation pump circulates hot water in a disinfection mode. The first pipeline is connected to the cold water tank through a vertical pipe installed in the cold water tank with an open upper end. A second pipeline connects the inlet pipeline to the hot water tank. A circulation pipeline connects the hot water outlet pipeline to the cold water outlet pipeline. A check valve is installed in the circulation pipeline allowing water to flow only from the hot water outlet pipeline to the cold water outlet pipeline.
