Embodiment Construction

[0043] refer to figure 1 , discloses a coffee grinder according to the invention, which is generally indicated by the reference number 1 .

[0044] The coffee grinder 1 comprises a container or hopper 2 for feeding coffee beans to a grinder assembly 3 for grinding coffee beans in a grinding chamber 30 . The motor 4 is connected to the grinding assembly 3 to activate or stop the grinding assembly 3 . A feed conduit 5 is connected to the grinding assembly 3 for feeding ground coffee into a filter 6 supported by a filter-holder 60 .

[0045] When the motor 4 is activated, the coffee beans are ground by the grinding assembly 3 and the ground coffee is supplied by the feed conduit 5 . When the motor 4 is stopped, the feed of ground coffee from the feed conduit 5 will be interrupted.

[0046] The motor 4 is a three-phase asynchronous motor. The electric motor 4 is connected with a frequency converter 7 for changing the rotational speed of the electric motor, which indicates the ...

Abstract

The invention relates to a coffee grinder (1). The coffee grinder comprises: a grinding assembly (3) to grind coffee beans, a container or hopper (2) to feed coffee beans to the grinding assembly (3),an electric motor (4) connected to the grinding assembly (3), a feeding conduit (5) connected to the grinding assembly (3) to feed coffee into a filter (6) supported by a filter-holder (60), an inverter (7) connected to the electric motor (4) to vary the speed of the electric motor, a control unit (C) connected to the inverter (7) to control the inverter, and a control panel (P) connected to theinverter (7) by means of the control unit (C) so that the user can vary the speed of the electric motor (4).

Description

technical field [0001] This patent application for industrial invention relates to a coffee grinder with a variable speed motor. Background technique [0002] Professional coffee machines are known to use a filter-holder with a filter which must be filled with one, two or more servings of ground coffee. Two conditions are necessary to ensure that coffee made with a coffee machine will retain its organoleptic characteristics: [0003] - coffee beans must be ground immediately before making coffee; and [0004] - The amount of ground coffee in the filter-holder must comply with the preset weight value for single or multiple servings. [0005] In fact, over time, ground coffee will lose its aroma; also, servings with little or too much ground coffee can create an unbalanced drink. [0006] In order to at least partly address these disadvantages, known coffee grinders include a grinding assembly actuated by an electric motor to grind coffee beans fed from a container or hoppe...
