Consumable recognition system and beverage dispenser

A consumable recognition system for recognizing placement and/or type of a consumable containing a food substance for the preparation of a beverage by use of a beverage dispenser, the consumable system comprising:

• a light sensor for sensing light reflected from a reflection element of the consumable during a relative movement between the consumable and the light sensor to obtain a sensor signal, wherein the sensor signal depends on position, reflectivity and/or pattern of said reflection element;
• a movable sensor carrier carrying said light sensor, wherein said light sensor is configured to sense the light reflected from said reflection element during a movement of said movable sensor carrier;
• a signal processor for recognizing the placement and/the or type of the consumable based on said sensor signal;
• and
• a position sensor for sensing a position of said movable sensor carrier, at which light reflected from said reflection element is sensed, wherein said sensor signal represents said position.

A consumable recognition system for recognizing placement and/or type of a consumable containing a food substance for the preparation of a beverage by use of a beverage dispenser, the consumable system comprising:

• a light sensor for sensing light reflected from a reflection element of the consumable during a relative movement between the consumable and the light sensor to obtain a sensor signal, wherein the sensor signal depends on position, reflectivity and/or pattern of said reflection element;
• a movable sensor carrier carrying said light sensor, wherein said movable sensor carrier is part of a lid of the beverage dispenser, and wherein said light sensor is configured to sense the light reflected from said reflection element during a linear movement of said movable sensor carrier;
• a signal processor for recognizing the placement and/or the type of the consumable based on said sensor signal;
• and
• an angle sensor for sensing an angular position of said lid based on the light reflected from said reflection element sensed by the light sensor, wherein said sensor signal represents said angular position.

A beverage dispenser for preparation of a beverage by use of a consumable containing a food substance, from which the beverage is obtained by use of extraction liquid, the beverage dispenser comprising:

• a consumable recognition system as for recognizing placement and/or type of the consumable,
• a chamber for receiving the consumable and for passage of extraction liquid through the consumable,
• a liquid processing unit for the passage of the extraction liquid through the consumable, and
• a controller for controlling one or more parameters of the beverage dispenser according to the recognized placement and/or type of the consumable,
• wherein the consumable system comprises
• a light sensor for sensing light reflected from a reflection element of the consumable during a relative movement between the consumable and the light sensor to obtain a sensor signal, wherein the sensor signal depends on position, reflectivity and/or pattern of said reflection element;
• a movable sensor carrier carrying said light sensor, wherein said light sensor is configured to sense the light reflected from said reflection element during a linear movement of said movable sensor carrier;
• a signal processor for recognizing the placement and/or the type of the consumable based on said sensor signal.

A beverage preparation system for preparation of a beverage, the beverage preparation system comprising:

• a beverage dispenser including:
• a consumable recognition system as for recognizing placement and/or type of a consumable from among a set of consumables,
• a chamber for receiving the consumable and for passage of extraction liquid through the consumable,
• a liquid processing unit for the passage of the extraction liquid through the consumable, and
• a controller for controlling one or more parameters of the beverage dispenser according to the recognized placement and/or type of consumable,
• wherein the consumable system comprises
• a light sensor for sensing light reflected from a reflection element of the consumable during a relative movement between the consumable and the light sensor to obtain a sensor signal, wherein the sensor signal depends on position, reflectivity and/or pattern of said reflection element;
• a movable sensor carrier carrying said light sensor, wherein said light sensor is configured to sense the light reflected from said reflection element during a linear movement of said movable sensor carrier;
• a signal processor for recognizing the placement and/or the type of the consumable based on said sensor signal,
• wherein the set of consumables comprises at least two consumables, each consumable of said set comprising a filtering body defining a space containing a food substance, from which the beverage is obtained and a reflection element for reflecting incident light during a relative movement between the consumable and a light sensor of a consumable recognition system, wherein said reflection element has a different position, reflectivity and/or pattern for each type of consumable of the set of consumables, said consumable being arranged in the chamber of the beverage dispenser.
