Embodiment Construction

[0053] The filter holders in these figures mainly consist of ( figure 1 ) body 1, handle 2 and coffee dispenser body 9. The coffee dispenser body 9 includes a flange 9.1 to facilitate its removal to allow cleaning of the filter.

[0054] Such as figure 2 As shown, the body 1 has an upper part 1.1 and a lower part 1.2. This lower part 1.2 encloses the lower cam 3, the upper cam 4, the brake lever for rotating the cams 3 and 4 around an axis parallel to the axis of the body, the filter-ejector 5 whose axis is the axis of rotation of the cams 3 and 4, A spring 6 that compresses the filter-ejector 5 axially (and generally downwards) and a pin 7 that pins the filter-ejector 5 to a corresponding pin slot provided on the lower part 1.2 of the main body 1 to engage the cam The rotation of 3 and 4 translates into an axial translation of the filter-displacer 5, since the cam can only rotate and the filter-displacer can only move axially.

[0055] Such as image 3 and 10As shown, ...

Abstract

Filter holder for a coffee machine comprising a main body (1) formed of an upper part (1.1) and a lower part (1.2), a filter-ejector (5) that can axially slide in said upper part (1.1), a first cam (4) that is located below the filter-ejector (5) and is adapted to engage and raise the latter upon a first relative rotation between both, in order to reduce the volume of the coffee powder to be brewed, and a second cam (3) that is fixed to the first cam (4) and is adapted to engage and further raise the filter-ejector (5) upon a second relative rotation between both, in order to eject the coffeegrounds after a coffee has been brewed. The filter-ejector (5) is keyed to said lower part (1.2), so that both the first and second cam can rotate with respect to it.

Description

technical field [0001] The present invention relates to a filter holder for a coffee machine and a coffee machine comprising said filter holder, in particular an espresso coffee machine, comprising: a main body; a filter-ejector, for filtering brewed coffee and ejecting coffee grounds and being axially slidable within said body; and a height adjustment mechanism comprising a first cam adapted to act as a filter-ejector and a first cam The initial or first relative rotation between engages and lifts the filter-ejector to reduce the volume of coffee grounds to be brewed. The height adjustment mechanism can be swapped between, for example, a double coffee position with a lower filter-ejector level and a single coffee position with a higher filter-ejector level, reducing the volume available for coffee powder in the filter holder . Background technique [0002] Such filter holders are used in espresso coffee machines where hot water is supplied at a pressure of 15 bar or more,...
