Detection and display device for automatic service expresso coffee machine
First Claim
1. Detection and display device for automatic service expresso coffee machine which automatically outputs and displays the number of ground coffee or water doses required for the desired infusion quantity, depending on the capacity of the filter-holder bowl engaged on the bowl-holder of the coffee grinder or coffee machine;
- automatic detection and display of the number of ground coffee or water doses according to the capacity of the filter-holder bowl are obtained by means of an actuator mounted on the filter-holder bowl and a detector mounted on the bowl-holder of the coffee grinder or coffee machine, characterized in that the actuator and detector form a system generating electric signals the number of which corresponds to the capacity in cups of the filter-holder bowl engaged on the bowl-holder, in that display of the number of cups corresponding to the capacity of the filter-holder bowl engaged on the bowl-holder is obtained by means of an electronic readout (14) and in that the number of water doses corresponding to the capacity of the filter-holder bowl engaged and the desired coffee strength is obtained by means of an electronic circuit controlled by strength selection keys (11 and
12) connecting the detector mounted on the bowl-holder to the water metering device (17).

Abstract
The invention concerns a detection and display device for automatic service expresso coffee machine which automatically outputs and displays water or ground coffee doses according to the capacity of the filter-holder bowl engaged on the bowl-holder of the coffee machine.
Detection and display are obtained by means of an actuator-detector system generating electric signals, such as one or more magnetic elements (5) mounted on filter-holder bowl (1) and a Hall effect detector (A) mounted on bowl-holder (11) of the coffee grinder or coffee machine.
