Disclosed is a temperature adjusting method for instant heating or cooling with an energy-saving water dispenser, the method including: installing a water dispenser, which includes a heating device, a control processor, etc.; coupling a water inlet to a tap water pipe and heating the water to 100 C., where the produced boiling water is split into two branches, one flows out from a high-temperature water outlet; the other branch flows through a preheater and performs heat exchange with cold water to achieve a temperature drop thus forming warm boiled water, which enters a refrigeration unit to be cooled to 5 C. When the user sets a single-time output water temperature and amount within an effective range, the control processor automatically matches the corresponding working mode and provides an accurate output according to the user-set single-time output water temperature and amount. There is further disclosed a water dispenser.

A beverage dispenser includes an inlet for drawing a liquid from a source and an outlet for outputting a beverage to a portable user vessel. A demineralization device demineralizes the liquid from the source and has an input and an output. The input of the demineralization device is coupled with the inlet. A beverage preparation device has an input and an output. The input of the beverage preparation device is coupled with the output of the demineralization device and the output of the beverage preparation device is coupled with the outlet. The beverage preparation device, the outlet, all active components and all passive components downstream of the demineralization device contacting the beverage are made of a biological inert material, particularly a biological inert metal, on any surface contacting the water. All couplings of the beverage dispenser are manufactured such that stagnation even of small quantities of beverage is avoided.

A beverage making pack according to an embodiment of the present disclosure may include a flexible container having a beverage making space, a pack body to which the flexible container is coupled and which has a pack opening communicating with the beverage making space and a seating part seated on a fermentation tank module, a tube connected to a lower portion of the pack body and accommodated in the flexible container, and a cap configured to open/close the pack opening.

A beverage-making apparatus includes a fermentation tank assembly including a fermentation tank having an opening formed therein and a fermentation tank cover configured to open and close the opening. The beverage-making apparatus also includes a refrigeration cycle apparatus including a compressor, a condenser, an expansion device, and an evaporator. The refrigeration cycle apparatus is configured to circulate a refrigerant therethrough and to control a temperature of the fermentation tank as the evaporator is disposed at the fermentation tank. The beverage-making apparatus further includes a heat insulating wall surrounding both the fermentation tank and the evaporator.

Bottom-loading bottled water dispensers are disclosed that include hot water sanitizing capabilities (and, optionally, UV light sanitizing features). The dispensers include a water bottle that is operably connected to a pump that is configured to extract water from the bottle and force the water through one or more tubes and into a cold tank. The cold tank includes an evaporator that is configured to chill the water in the cold tank. The dispensers further include a hot tank that is fluidly coupled to the cold tank through one or more tubes, with the hot tank being attached to a heating element that is configured to heat the water in the hot tank. In addition, the dispensers include an electronic control board that is configured to heat a volume of water contained in the cold tank above a defined threshold temperature and for a defined period of time that is effective to sanitize the internal surfaces of the cold tank.

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.

The subject matter discloses a water dispenser, comprising a water container, a water supply system, a fluid pump and a control unit. The water supply system is configured to supply water from the water container to a hot water reservoir and to a cold water reservoir and is further configured to provide hot water from said hot water reservoir and cold water from said cold water reservoir to a user of said water dispenser. The fluid pump is fluidly coupled to a fluid flow system and the water supply system and is configured to pump a quantity of hot water from the hot water reservoir to the water container via a fluid flow conduit of the fluid flow system for a cleansing operation of at least the fluid flow system. The control unit is in communication with the fluid pump for controlling the cleansing operation.
