Device for sensing a capsule in a beverage production apparatus

摘要

The invention aims to provide a device sensing a capsule (2) inserted in a receptacle (1) in machine and physical parameters of liquid supplied by a beverage production apparatus flowing through the capsule in function of the type of capsule. The capsule containing beverage ingredient is inserted in a cylindrical or conical wide mouthed receptacle having an upper opening for inserting the capsule and a lower bottom closing the receptacle. The receptacle rotates around an axis of a hollow shaft (3) attached at the center and perpendicularly to the external face of the bottom of the receptacle, said shaft forming a hole at the center of the inner face of the bottom of the receptacle. The device comprises a rod sliding in the shaft and passing through the hole of the inner face of the bottom of the receptacle, said rod (4) being provided with a spring maintaining an end of the rod lifted inside the receptacle in contact with the capsule, the other end being inside the shaft. The device further comprising means for measuring the position of the end of the rod in the shaft, in order to control, in function of the size of the capsule inserted in the receptacle, rotation speed of the receptacle, discharge and physical parameters of liquid supplied by the beverage production apparatus flowing through the capsule.
