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.

A platform for onsite creation of consumable liquids is provided. The platform includes a liquid generating machine, a set of cubes, compatible bottles, and a user interface device. The liquid generating machine may include a water storage module, a cube module, a liquid making module and a bottle filling and cleaning module. The platform decentralizes the production of consumable liquids, such as drinking waters, enhances the consumer's experience, significantly increases consumers' choices, all while simplifying the consumption process (buying the water, carrying it, getting rid of/recycling the plastic bottle, etc.). The platform includes customizable liquid generating recipes associated with the cubes that may be provided through a network or local database and a security feature that allows the authorization of users to generate and access controlled liquids.

A multiple-piece vacuum-insulated heating tank for use in a water dispenser includes a threaded cover, a thermal insulation cover, and a heating tank body. The threaded cover is mounted on an upper opening of the heating tank body and includes a plastic cover and a protective cover mounted on and around the plastic cover. The thermal insulation cover is fitted in the upper opening and includes an upper cover and a lower cover. The lower cover is cup-shaped; is mounted with a heating tube, a water inlet pipe, a water outlet pipe, a thermowell, a temperature-sensing heat pipe, a heat collector block, and two snap-action thermostats at the bottom side; and has a sidewall formed with a step adjacent to the bottom side. The heating tank not only has a multiple-piece structure that facilitates mass production and maintenance, but also dispenses with electronic temperature control as is conventionally required.

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.

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 water purifier includes a working coil, a hot water tank that faces toward the working coil and is spaced apart from the working coil by a gap to heat a liquid passing through an inner space of the hot water tank by an induction of the working coil, a bracket that is coupled to the hot water tank, the working coil being located between the hot water tank and the bracket, and a spacer that is located between the working coil and the hot water tank to thereby define the gap between the working coil and the hot water tank.
