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.

A soda maker having convenient gas intake and discharge comprises main, auxiliary unit. Main unit comprises housing, base, carbon dioxide cylinder provided within the housing, gas intake main body provided at top of carbon dioxide cylinder, gas intake support, gas intake connecting rod, locking engagement member. The auxiliary unit comprises outer casing, auxiliary unit main body, water bottle, tapered ring, soda bottle. The auxiliary unit main body provides gas discharge valve and switch valve. The housing provides installation hole. The soda maker further comprises pivoting base having side and top opening. The pivoting base fixed within housing, pivoting plate passes through installation hole, half shaft is pivoted half shaft hole. While operation, positioning protrusion engages with operation positioning blind hole, axis of connecting part parallels to horizontal plane, gas discharge valve engages end plate of pivoting base, switch valve engages locking engagement member. The positioning protrusion engages gas discharge positioning blind hole. The structure enables auxiliary unit to rotate by specific angle when operation complete, automatic gas discharge achieves before soda bottle removal performed, very convenience.

In order to reduce limescale formation on the continuous flow heater during operation of an apparatus for preparing freshly brewed hot beverages which has a hot water generator, which is embodied as a continuous flow heater, and a brewing apparatus, to which hot water from the hot water generator can be supplied, a controller for actuating the continuous flow heater is provided, which controller switches on the continuous flow heater for the purpose of drawing a pre-specified quantity of hot water and switches off said continuous flow heater shortly before the quantity of hot water is completely output, so that the temperature of the hot water at the output of the continuous flow heater is declining at the end of the drawing operation.

An appliance (100, 200) for heating a liquid to make a beverage, the appliance (1) including: a sensor assembly (10) including: a duct (12) having an inlet (18) and an outlet (20), the duct (12) defining a liquid flow path (21) between the inlet (18) and the outlet (20) for the liquid; a sensor (22) having an operative end portion (28) in the flow path (21) for measuring line parameters of the liquid in the flow path (21); and a nozzle (34) to receive water under pressure and direct a water jet transverse to the flow path (21) and towards the operative end portion (28) of the sensor (22) to at least aid in cleaning the operative end portion (28) of the sensor (22).

A system for preparing a brewed beverage from at least one flavorant includes a housing, a receptacle connectable to the housing for holding the at least one flavorant and a reservoir connectable to the housing. The receptacle including a first fluid inlet and a second fluid inlet and a first fluid flow path fluidly connects the reservoir to the first fluid inlet and a second fluid flow path fluidly connects the reservoir to the second fluid inlet.

Ingredient dispensing systems and methods are disclosed. A disclosed system includes an ingredient reservoir and an electromechanical valve configured so that, when the electromechanical valve is activated, an ingredient is dispensed from the ingredient reservoir. The disclosed system also includes a current sensor configured to measure a current draw of the electromechanical valve. The disclosed system also includes a controller programmed to sample the current draw from the current sensor and to detect a dispense error of the electromechanical valve based on the sampled current draw.

A valve body structure is provided and includes a main pipe, a secondary pipe and a liquid storage tank, where the liquid storage tank stores a second liquid from the secondary pipe and controls whether the second liquid in the liquid storage tank flows into the main pipe by a solenoid valve, so that the second liquid is mixed with a first liquid in the main pipe. Therefore, the valve body structure can mix liquids without combining other components and has a lower cost and a smaller volume. As such, the issue of the remaining residual liquid when combined with other components for control, which reduces the control accuracy and even causes the problem of mixed pollution, can be avoided.
