Disclosed are a water purifier and a control method thereof for controlling a main body by executing an artificial intelligence (AI) algorithm or a machine learning algorithm in a 5G environment established for the Internet of things. The control method of the water purifier according to the present disclosure includes a photographing step, a scanning step, a recognizing step, a calculating step, a determining step, and a water discharging step. When the water discharging step is initiated, the distance sensor generates real-time height information on the water surface, and may stop discharging water before a real-time height exceeds the highest point height.

A water purifier includes a hot water tank for receiving and heating received water by induction heating, a water outlet portion that is at least partially exposed to an outside of the water purifier for discharging hot water, a hot water line that is connected to the water outlet portion to communicate the hot water from the hot water tank to the water outlet portion, a hot water outlet valve that is located at the hot water line and that opens or closes the hot water line based on a control command, a connector that includes a hot water inlet connected to a water outlet pipe of the hot water tank and a hot water outlet connected to the hot water line, and a temperature sensor that is connected to the connector and that is configured to measure a temperature of the hot water that passes through the connector.

A fluid heating system including a heating chamber that receives fluid and heats the fluid to provide heated fluid, a dispensing device that dispenses the heated fluid, the dispensing device encompassing the heating chamber, a thermostatic control device that regulates a power supply to the heating chamber, an energy recovery device that harvests mechanical energy provided by a flow of the heated fluid from the heating chamber to the dispensing device and generates electrical energy to power the thermostatic control device, a pressure regulating valve, wherein in a closed position, passage for the heated fluid is prevented between the heating chamber and the drain when a pressure in the heating chamber is below a predetermined pressure threshold and passage for the heated fluid is provided between the heating chamber and the drain when the pressure in the heating chamber is above the predetermined pressure threshold.

Content containers and vessels, one aspect including a deformable fluid-tight container shell defining an internal volume and separating the internal volume from an external environment; a room-temperature semi-solid content contained within the internal volume; and a valve operationally connected to and disposed at least partially without the deformable container shell; where the semi-solid content is a hydrophobic matrix with at least partially emulsified hydrophilic components; where the container shell is substantially fluid-tight; where the valve has open state(s) and a closed state; where the valve may be actuated between the open state(s) and the closed state; where the valve is self-cleaning; where during the open state(s), the internal volume is in fluidic communication with the external environment; where during the closed state, the internal volume content cannot fluidically communicate with the external environment; and where the content remains moisture-stable while the valve is in the closed state.

Methods for treating and preparing chocolate. In one aspect, a method includes heating a quantity of chocolate to a temperature of about 46 degrees Celsius; decreasing the pressure of in a pressure-controllable environment to about 25 Torr; holding the pressure of the pressure-controllable environment at about 25 Torr for a first predetermined period of time; decreasing the pressure of the pressure-controllable environment to about 5 Torr; and holding the pressure of the pressure-controllable environment at about 5 Torr for a second predetermined period of time. Other aspects include ceasing heating the quantity of chocolate; decreasing pressure occurs at an average rate of about 150 Torr per minute; decreasing pressure occurs at an average rate of about 4 Torr per minute; and others.

Apparatus and systems for melting and liquefying chocolate. In one aspect, a system includes a generally fluid-tight exterior housing defining a first volume; a bulkhead positioned within the housing and dividing the first volume into separate second and third volumes; at least one vertical support member operationally connected to the exterior housing; a base support member operationally connected to the vertical support member; a dispenser guiding member disposed within the first volume and operationally connected to the exterior housing; and a heating element in thermal communication with the first volume, wherein energization heats the first volume to 37 to 46 degrees Celsius. Other aspects include where the liquid chocolate contains less than 3% water; where the liquid chocolate is solid at room temperature; a multiple pivot hinge; and a noninterfering interdigitating hinge.

A beverage dispense system for a countertop having a water inlet including a solenoid valve and a beverage concentrate inlet to which a bag-in-box containing a supply of liquid coffee concentrate is attached. A beverage dispense font is mounted on the countertop. A water conduit connects the water inlet with the dispense font. A separate liquid beverage concentrate conduit connects the beverage concentrate inlet with the beverage dispense font. An electric syrup pump pumps liquid coffee concentrate from the bag-in-box to the end of the dispense font. A control unit controls the separate delivery of water from the mains water inlet and/or liquid coffee concentrate to the end of the beverage dispense font. Where water and liquid coffee concentrate are delivered, they will mix in the beverage receptacle.

An apparatus and method may be configured for detecting selection between a hot version and a cold version of a beverage, causing opening of a first of a plurality of valves and closing of a second of the plurality of valves for providing water to a first of a plurality of mixing chambers based on the selection, causing delivery of beverage concentrate to the first mixing chamber, controlling a flow rate of the water and a flow rate of the beverage concentrate into the mixing chamber for mixing of the water with the beverage concentrate in a controlled ratio to create the beverage, and dispensing the beverage from the mixing chamber.

A fluid heating system including a heating chamber that receives fluid and heats the fluid to provide heated fluid, a dispensing device that dispenses the heated fluid, the dispensing device encompassing the heating chamber, a thermostatic control device that regulates a power supply to the heating chamber, an energy recovery device that harvests mechanical energy provided by a flow of the heated fluid from the heating chamber to the dispensing device and generates electrical energy to power the thermostatic control device, a pressure regulating valve, wherein in a closed position, passage for the heated fluid is prevented between the heating chamber and the drain when a pressure in the heating chamber is below a predetermined pressure threshold and passage for the heated fluid is provided between the heating chamber and the drain when the pressure in the heating chamber is above the predetermined pressure threshold.
