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 fully automatic beverage machine for preparing freshly brewed hot beverages, having at least one hot-water generator (10, 20), a brewing device (50) to which hot water can be supplied from the hot water generator (10, 20), and a water pump (11, 21) which pumps drinking water from a drinking water supply line (30) to the hot water generator (10, 20). The hot water generator (10, 20) is a continuous flow heater and a flowmeter (12, 22) for determining the volume of drinking water pumped by the water pump (11, 21). Additionally, the fully automatic beverage machine is equipped with an automatic decalcification system (40) for automatically decalcifying the continuous flow heater (10, 20). The decalcification system has a mixing container (41) for mixing a descaling solution, a receiving chamber for a storage container (42) for liquid decalcifier concentrate, and a metering pump (43) for pumping decalcifier concentrate out of the storage container (42) into the mixing container (41) in a metered manner, wherein the descaling solution is mixed from decalcifier agent concentrate and water in the mixing container. The water pump (11, 21) can be connected to a removal line (49) of the mixing container (41) in a switchable manner on the suction side via a first directional valve (44) in order to pump the descaling solution from the mixing container (41) to the hot water generator (10, 20) in the switched valve position of the first directional valve (44), and the water pump (11) can be connected to a water supply line (47) of the mixing container (41) in a switchable manner on the pressure side via a second directional valve (45) in order to pump drinking water to the mixing container (41) in the switched valve position of the second directional valve (45).

A beverage preparation apparatus and method are provided, the apparatus including a brewing chamber, at least one pump configured to supply a diluent to the brewing chamber, two heaters configured to heat the diluent, at least one heater of the two heaters being a pipe heater, a controller configured to independently supply power to one or both of the heaters as a function of a flow rate and of a temperature of the diluent.

Method and machine for preparing beverages, in particular infusions, such as coffee or tea, having a liquid supply source supplying a liquid, in particular water, an infusion chamber and an infusion circuit, which connects said supply source to said infusion chamber; the machine having an infusion circuit with a heat exchanger and a dispensing assembly, which is configured to heat the liquid at a predetermined temperature that is lower than the boiling temperature of the liquid, for example at approximately 90°, before the infusion of the liquid itself on the inside of the infusion chamber.

A coffee brewer contains a brewing unit in which coffee grounds having been poured in are compressed by a plunger driven by an actuator. Heated water flows through the compressed coffee grounds. A control device controls the actuator in accordance with signals of an angle of rotation sensor. The control device first moves the plunger against a stop in an ejection position to calibrate the sensor, then moves the plunger by a predetermined distance in a downwards direction into a pouring-in position. Afterwards the control device moves the plunger by a second distance into the brewing position, a length of the predetermined distance and the second distance corresponds to a number of pulses of the sensor which are stored in the memory. The control device subsequently moves the plunger by a third distance back into the ejection position in which the coffee grounds are removed from the plunger.

An appliance for making a beverage, the appliance comprising: a plurality of heating components for heating a liquid, and a power management system, wherein the power management system comprises: an energy storage device, wherein at least a first function of the appliance requires simultaneous operation of a first heating component and a second heating component of the plurality of heating components, and wherein at least the first heating component comprises a first heater element and a second heater element, where the first heater element is powered using mains power, and the second heater element is powered using the energy storage device.

A system and method. The system may include a beverage machine including a pump, heater, a sensor, and a processor. The pump may be configured to pump fluid including gas or liquid. The heater may be configured to heat the fluid. The sensor may be implemented downstream of the pump and the heater. The sensor may be configured to sense a pressure, a flow rate, a steam quality, or a temperature of the heated fluid and to output sensor data including information of the pressure, the flow rate, the steam quality, or the temperature of the heated fluid. The processor may be communicatively coupled to the heater, the pump, and the sensor. The processor may be configured to: receive the sensor data; control operation of the pump or the heater; and based on the sensor data, adjust an operational parameter of the pump or the heater.

The invention concerns a unit for controlling transmission of power to a thermal conditioning device e.g. for coffee machine, comprising a controller with a start-up profile for starting-up the device from a temperature of inactivity to an operative temperature for bringing to a target temperature a fluid circulating through said device at start-up end, the controller being arranged to allow circulation of fluid through the device at start-up end and to compare the determined temperature of fluid circulated at start-up end to the target temperature and derive a temperature difference therefrom. The start-up profile has at least one parameter and in that the controller has a self-learning mode for adjusting the parameter as a function of the temperature difference and to store the adjusted parameter for a subsequent starting-up of the device.
