Abstract:
A combination of a flow meter and printed circuit board or flex-print for a liquid food or a beverage preparation machine, which board or flex-print is rigidly connected to the flow meter. This combination is used in a liquid food or beverage preparation machine that includes an in-line heating device in which machine liquid is circulated through the heating device and then guided into a brewing chamber that includes a capsule or pod housing for brewing a food or beverage ingredient supplied into the brewing chamber.
Abstract:
The present invention presents a pumping system (1) with a preheated reservoir (2), a main pump (4) for pumping a preheated liquid (3) from the reservoir (2), and pressurizing means (5) for pressurizing the reservoir (2). Preferably, the pressurizing means set an absolute pressure of 0.5 to 1 bar in the reservoir (2). The liquid (3) in the reservoir (2) can be heated up to 90° C. or more. The present invention achieves a nearly complete suppression of the phenomenon of cavitation at the main pump entrance, and thus achieves an increased pumping performance at elevated liquid temperatures.
Abstract:
An in-line heater for a liquid food or beverage preparation machine, in which machine liquid is circulated through the heater and then guided into a brewing chamber for brewing a food or beverage ingredient supplied into said brewing chamber. The heater has a body incorporating an inlet, an outlet and a heating chamber extending therebetween, with the inlet, outlet and heating chamber forming together a rigid passage for guiding the liquid circulating through the body, and one or more electric components that are secured on or in the body and connected to a printed circuit board arranged to control the heater. The one or more electric components are rigidly connected to the printed circuit board.
Abstract:
A beverage preparation machine is disclosed that includes a base and at least one module. The base conditions and delivers a fluid to the at least one module that houses an ingredient to be mixed with the fluid. The base is controlled by a control unit that is configured to control the flow and the pressure of the liquid delivered to the module, during the preparation of a beverage, according to a command selected from a plurality of commands suitable for different types of ingredients and/or for different preparation processes of a given ingredient.
Abstract:
A liquid food or beverage preparation machine that includes a fluid arrangement and a printed circuit board for controlling one or more functions of the fluid arrangement, with the printed circuit board being enclosed within a substantially impervious housing to protect the printed circuit board from fluid or vapor emissions from the fluid arrangement.
Abstract:
The invention relates to a beverage machine that includes a brewing unit which can be opened for introducing or removing an ingredient capsule and closed for brewing a beverage from the ingredient capsule; a passage having an opening and which is arranged for guiding the ingredient capsule from the passage opening into the brewing unit; and a closing part for closing the passage opening when the brewing unit is closed. The closing part is relatively movable over the passage opening with a generally parallel relative movement thereto from an open relative position in which the ingredient capsule can be passed into the brewing unit via the passage to a closed relative position, in which the passage opening is closed by the closure member. The closing part optionally extends over edges of the passage opening.
Abstract:
A liquid food of beverage preparation machine that includes an electric supply circuit connectable to an electric power source; a heater powered by the electric supply circuit; and a thermal fuse device in thermal communication with the heater and associated with the electric supply circuit, the fuse device being arranged to interrupt the electric supply circuit from the power source when the heater exceeds a temperature limit. The thermal fuse device is reversible and includes a switch for automatically interrupting the electric supply circuit when the heater exceeds the temperature limit, the switch being operable by a user to close the electric supply circuit when the heater has a temperature that has returned below the temperature limit.
