Problems solved by technology

However, if the sensor is designed to detect the motor current and deduce therefrom the upward movement of the reciprocating piston, as is usual in practice, ie the rotational speed of a DC motor is in principle reciprocal with respect to the current consumption, one must take into account The inaccuracy of this indirect determination of rotational speed and consequently of the determination of filling height

Embodiment Construction

[0020] exist figure 1 and 2 shows a ferromagnetic gear 1 with straight toothing, which is made of a ferrous alloy and is part of a transmission denoted overall by 2 . The transmission 2 is driven by an unshown DC motor.

[0021] The components of the transmission 2 including the ferromagnetic gear 1 are mounted rotatably on a mounting plate 3 of the fully automatic coffee machine. A DC motor driving the transmission 2 is not visible.

[0022] Radially facing the teeth of the ferromagnetic gear 1 and at the same height as the teeth, a Hall sensor / magnet unit 4 is mounted on the mounting plate, precisely by means of a mounting plate 3 and connected to the interface 6 The printed circuit board 5 is contacted. These interfaces 6 lead to an electronic control unit (not shown), a counter or an analog-to-digital converter.

[0023] as by figure 1 and 2 As can be seen in detail, the Hall sensor 4a of the Hall sensor / magnet unit 4 is arranged between a permanent magnet 4b and th...

Abstract

The invention relates to a fully automatic coffee machine. The fully automatic coffee machine includes a position detection device and / or positioning speed detection device on a positionable or adjustable unit of the fully automatic coffee machine, wherein a ferromagnetic tooth wheel (1) is pivoted with a drive line of the positionable or adjustable unit. The position detection device and / or positioning control device comprises a Hall sensor / magnet unit (4) which is disposed vis-a-vis of a toothing of the ferromagnetic tooth wheel (1).

Description

technical field [0001] The invention relates to a fully automatic coffee machine with a position detection device and / or adjustment on a positionable or adjustable unit of the fully automatic coffee machine, in particular a brewing unit and / or a part of the brewing unit Speed ​​detection device. Background technique [0002] In a known Italian espresso machine, there is a positively controlled reciprocating piston and a sliding carriage with an ejector movable over an opening in the brewing chamber and brewing This opening of the chamber is sealed in an operating position of the sliding seat by means of a piston-shaped section on the underside of the sliding seat, a brewing chamber sleeve forming the peripheral wall of the brewing chamber is positively controlled in an operating position of the sliding seat Can be moved into a sealing position and can be moved back to a rest position after a brewing process (DE 20 2004 018 776U1). A reciprocating piston of the brewing cham...
