ABSTRACT:
A drip coffee maker comprises a housing (10), and in the housing (10) a filter holder (20) into which ground coffee (23) is to be poured. A measuring device (25) is provided for the ground coffee poured into the filter holder (20). The filter holder (20) is mounted movably in the housing, and the measuring device (25) comprises at least one deformable mechanical member (33) connected to the filter holder (20) and reacting by deformation to the quantity of ground coffee (23) poured into the filter holder. This deformable mechanical member (33) drives by its deformation a member (35) for visual indication of the desired quantity of ground coffee. The deformable member (33) is in stable position when that desired quantity of ground coffee is obtained. The deformable member (33) is comprised by four articulated arms (38a, 38b, 38c, 38d) constituting a deformable parallelogram (38), one (38a) of the arms of one of two pairs of arms of the parallelogram (38) being mechanically connected to the filter holder (20) and being connected with a resilient member (43) mounted in the housing so as to maintain in stable equilibrium the parallelogram (38) when the desired quantity of ground coffee is obtained, and one (38d) of the arms of the other pair of arms of the parallelogram (38) being connected to the visible indication member (35).
