Embodiment Construction

[0010] As can be seen from the figures, the grinder-dispenser according to the invention has a base 2 supporting a bell-shaped container 4 for containing coffee beans and a dispenser 6 for dispensing ground coffee.

[0011] Mounted in the base 2 is a motor 8 of the vertical axis type, the shaft 10 of which is rigidly connected to a cooling fan 12 and a pulley 14 .

[0012] The pulley 14 is connected by a belt 16 to a driven pulley 18 having a larger diameter than the pulley 14 .

[0013] The driven wheel 18 is rigidly connected in a rotatable manner to a shaft 20, the upper end of which is provided with a recessed seat 22 which engages a corresponding head 24 of a shaft 26 which makes the driven grinding wheel 28 rigidly rotate Engaged, the driven grinding wheel is disposed within the grinding chamber 36 .

[0014] The shaft 26 is axially guided by ball bearings 30 inserted into a bushing 32 on which the driven grinding wheel 28 rests.

[0015] Shaft 26 is free to rotate wit...

Abstract

A coffee grinder includes a support base containing a grinding chamber, the base housing an electric motor coupled to a first shaft, to which a second shaft rotatably coupled but which is axially free, the second shaft rotating a movable grinding wheel; a sleeve, within which the second shaft rotates freely but is axially restrained, and which has a threaded lateral surface cooperating with a threaded portion rigidly coupled to the base, the movable grinding wheel being axially constrained to the sleeve; a fixed grinding wheel facing the movable grinding wheel in the interior of the grinding chamber, the fixed grinding wheel being fixedly coupled to the base frame; and a moving system that translates the sleeve axially.

Description

technical field [0001] The invention relates to a coffee grinder-dispenser. Background technique [0002] Coffee grinder-dispensers are known to comprise a housing housing two oppositely arranged grinding wheels, one of which is rotated by an electric motor and the other can be rotated by means of a threaded ring incorporated into the grinding wheel holder. The operation moves axially relative to the previous grinding wheel. [0003] In these grinder-distributors, the continuous adjustment of the grind degree is achieved by a threaded coupling arrangement, which enables an axial approach and return movement of the grinding wheel in the grinding chamber, which is axially movable relative to the grinding wheel rotated by the motor. [0004] However, this known grinder-dispenser has the disadvantage that, after disengaging one of the two grinding wheels in order to clean the grinding chamber, a lengthy and laborious operation is required to bring the grinding wheels back to th...
