Abstract:
A beverage machine arranged to image at least a portion of a capsule held by a beverage forming station of the machine. Parts of the beverage forming station may be movable between open and closed positions, and a portion of the capsule may be imaged while parts of the forming station are between open and closed positions. A capsule image may be captured only when forming station parts are moved toward the closed position, and image date discarded if the forming station is moved toward the open position prior to beverage formation.
Abstract:
An inlet arrangement of a beverage forming apparatus is provided, where the inlet arrangement is configured to deliver liquid to a beverage cartridge. The inlet arrangement includes a central inlet port and a plurality of inlet ports arranged around the central inlet port. The beverage forming apparatus has the ability to implement different dispensing operations in which dispensing occurs through selectable subsets of the inlet ports.
Abstract:
Methods and cartridges for carbonating or otherwise dissolving gas in a precursor liquid, such as water, to form a beverage. A gas source is provided in a cartridge which is used to generate gas that is dissolved into the precursor liquid. A beverage medium, such as a powdered drink mix or liquid syrup, may be provided in the same, or a separate cartridge as the gas source and mixed with the precursor liquid to form a beverage. The gas source includes a solid molecular sieve formed in beads in which at least 85% of the beads by weight have a size of 0.71mm to 2.0mm.
Abstract:
A beverage making machine (1) may be arranged to cool a precursor liquid in a tank using a cooling liquid in a cooling container disposed around the tank. The cooling liquid may be freezable to form ice, e.g., to provide the system with improved cooling capacity and/or speed. A plurality of fins (63,73) may extend between the tank (6) and the cooling container (71), with each of the plurality of fins being physically attached to the cooling container or the tank and being arranged to conduct heat from the tank and/or from the cooling liquid. The plurality of fins (63,73) may include first portions attached to the tank and extending outwardly, and second portions attached to the cooling container and extending inwardly. Side surfaces of corresponding first and second portions may be in contact with each other to aid in transferring heat via the fin portions.
Abstract:
A method and apparatus for opening and closing a cartridge holder (3) of a beverage forming machine (10). The cartridge holder (3) may have an opening (31) arranged to receive and hold a cartridge (1) with the cartridge holder in an open position, e.g., the opening (31) may face a front of the beverage forming machine and be in an upwardly inclined position in the open position. A cam (34) and cam follower (63) may cause the cartridge holder (3) to pivot and move to a closed position, e.g., in which the opening (31) of the cartridge holder (3) is in a downwardly inclined orientation. Rotation of the cartridge holder (3) may be damped in at least a portion of movement between the open and closed positions.
Abstract:
A beverage forming method and system in which a heater tank (152) can be filled with liquid to an expansion level (159) after a beverage is formed. The liquid in the heater tank may be heated, causing expansion of the liquid in the tank. Thereafter, a volume of liquid may be delivered to the tank to fill the tank to a liquid delivery level (160) at which the tank is filled to deliver a controlled volume of liquid to form a beverage. No further heating of liquid in the tank may be performed or required after filling to the delivery level since the volume of liquid delivered to fill the tank to the liquid delivery level may be relatively small. Accurate volumes of liquid may be delivered in a way that compensates for any expansion that may occur due to heating.
Abstract:
Systems and methods for controlling liquid flow to the liquid supply of a beverage forming apparatus. The liquid supply (15) may include two valves (151a, 151b) positioned in series for controlling a flow of a liquid into the liquid supply. Pressures upstream, between and/or downstream of the valves may be detected and used to determine if one or both of the valves leak when closed.
Abstract:
Methods and systems for employing a sensor to detect two physical characteristics of a liquid in a beverage machine. A sensor may have a conductive probe portion to contact liquid, e.g., to detect a liquid level in a removable water tank, and a thermistor portion to detect a temperature of the liquid.
Abstract:
Methods and systems for employing a sensor to detect disconnection of a liquid supply tank and a low fill level of the liquid supply tank are disclosed herein. The sensor may have a conductive probe to contact liquid, e.g., to detect a liquid level in a removable liquid supply tank.
Abstract:
A beverage machine having a heater tank with a horizontally oriented heating element. The heating element may be arranged as a helical coil with a longitudinal axis arranged horizontally in the heater tank. A bottom wall of the heater tank may define a concave shape at the interior of the heater tank, and the heating element may be at least partially arranged within the concave shape, e.g., with a longitudinal axis of the coil extending along a central portion of the bottom wall. An inlet to the heater tank may be arranged at the bottom wall, e.g., in the central portion of the bottom wall, and may direct liquid at the heating element.
