Abstract: Methods and systems of determining the amount of liquid in a liquid supply tank of a beverage forming machine without a dedicated sensor are disclosed herein. In some embodiments, the beverage forming machine includes a controller capable of determining the amount of liquid in the liquid supply tank based on a gas volume in a reference vessel, such as a conduit, in fluid communication with the liquid supply tank.

Abstract: A beverage preparation machine having an inlet arrangement and a gasket arrangement is provided, where the inlet arrangement is configured with a plurality of inlet ports to deliver liquid to a beverage cartridge. The gasket arrangement may include a single unitary shape with a plurality of openings for receiving the plurality of inlet ports. The gasket arrangement may include one or more inner ribs disposed about each of the plurality of openings. A perimeter rib may extend along a perimeter of the gasket arrangement.

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: 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. A gasket arrangement may be used with the inlet arrangement.

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.

Abstract: A beverage preparation machine having an inlet arrangement and a gasket arrangement is provided, where the inlet arrangement is configured with a plurality of inlet ports to deliver liquid to a beverage cartridge. The gasket arrangement may include a plurality of openings, wherein each of the plurality of inlet ports is received within one of the plurality of openings. The gasket arrangement may be integrally formed and may include one or more ribs disposed about each of the plurality of openings. A perimeter rib may extend along a perimeter of the gasket arrangement.

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: A beverage machine having a heater arranged to receive unheated liquid and deliver heated liquid to a dispensing station to form a beverage, and to receive unheated air and deliver heated air to the dispensing station to preheat portions of the dispensing station before forming a beverage. The machine may be arranged to deliver heated air to the dispensing station only if a temperature at the dispensing station is below a threshold.
