Abstract: Filter-holder comprising a cup (3) receiving a coffee filter (10) and having a perforated bottom, a body (25) arranged under the filter, an infusion collecting chamber (41) opening into a channel (43) of which the outlet (45) communicates with at least one distribution funnel (32), and a foam-forming device. According to the invention, the channel (43) extends annularly about a bossing (39) provided on the body, and the foam-forming device has an elastic annular seal (48) arranged about the bossing, closing the outlet (45) of the channel (43) and deformable by expansion in order to form at least one infusion flowing passage (51). Application particularly to a filter-holder for domestic coffee machines.
Abstract: The invention relates to a domestic coffee maker having in a housing (1) with a front face, a cold water tank and a filter (4) having an outflow orifice (7) situated above an infusion collection jug (8) resting on a base (9). The filter (4) is equipped with a shut-off valve (13) for the outflow orifice (7). The shut-off valve is controlled by an actuating device which is movable relative to the housing. Displacement of the actuating device is caused by the positioning and removal of the jug (8) on the base. A substantial portion of the base (9) projects beyond the front face of housing (1). The filter (4) is enclosed within the housing (1). The actuating device comprises a rod (14) which is mounted to slide horizontally under the filter (4) against the urging of an elastic device (15). One end (16) of the rod (14) controls the valve (13). Movement of the rod (14) is controlled by a movement multiplier device actuated in response to the presence or absence of the pouring spout (12).
Abstract: The present invention concerns a water filter designed to be inserted into a drinking water circuit. The water filter has a support designed to house removably one or more different filters each having a different filtering property and adapted to be mounted either independently of each other or associated in a particular combination so as to effect a filtration of the drinking water according to its composition.
