Abstract
Abstract The invention relates to a coffee brewing machine which is particularly suitable for family use and for a small commercial establishment, such as a refreshment room. The machine extracts the coffee beverage from a pod which contains ground coffee and is housed in a chamber defined by an upper block and by a removable lower box, between a jet-forming member fixed to the upper block and a filter housed in the removable lower box. It includes a water container, a heater and a pump which supplies the water to the chamber at the proper temperature and pressure. In the chamber the water penetrates the pod and extracts the coffee beverage therefrom and then the coffee beverage flows out of the machine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
176 words
A hot-beverage machine, particularly a coffee maker, comprising a housing having a reservoir for water; means on said housing forming a brewing chamber having an inlet and an outlet and including a removable cover for the chamber; filter means in said chamber intermediate said inlet and outlet thereof; means for removably holding in said chamber, intermediate and spaced from both said inlet and said filter, a water-permeable cartridge containing a beverage-making substance; a distributor member removably mounted on said housing and to which said chamber-forming means are connected, said distributor member having one surface provided with an annular recess forming an annular distributing chamber of a first cross-section, and an annulus of distributing passages of second cross-section smaller than said first cross-section and each communicating with said intake and with said annular recess, respectively; electrically energized means for heating water from said reservoir; and means for forcing the heated water under pressure through said intake, said inlet and said cartridge into said chamber, so as to brew a beverage which leaves said chamber through said outlet.
Claim 2
Dependent Claim
176 words
A hot-beverage machine, particularly a coffee maker, comprising a housing having a reservoir for water; means on said housing forming a brewing chamber having an inlet and an outlet and including a removable cover for the chamber; filter means in said chamber intermediate said inlet and outlet thereof; means for removably holding in said chamber, intermediate and spaced from both said inlet and said filter, a water-permeable cartridge containing a beverage-making substance; a distributor member removably mounted on said housing and to which said chamber-forming means are connected, said distributor member having one surface provided with an annular recess forming an annular distributing chamber of a first cross-section, and an annulus of distributing passages of second cross-section smaller than said first cross-section and each communicating with said intake and with said annular recess, respectively; electrically energized means for heating water from said reservoir; and means for forcing the heated water under pressure through said intake, said inlet and said cartridge into said chamber, so as to brew a beverage which leaves said chamber through said outlet.
Claim 3
Dependent Claim
33 words
A machine as defined in claim 1, wherein said chamber-forming means comprises an upper member mounted on said housing and, a lower member removably mounted on said upper member and constituting said cover.
Claim 4
Dependent Claim
31 words
A machine as defined in claim 2, said holding means being constituted by respective juxtaposed edge faces of said upper and lower members between which portions of the cartridge are clamped.
Claim 5
Dependent Claim
25 words
A machine as defined in claim 1; and further comprising means adjacent said inlet for directing high-speed jets of the heated water against said cartridge.
Claim 6
Dependent Claim
64 words
A machine as defined in claim 1; said heating means including a casing having a compartment for water to be heated and communicating with said intake passage; and wherein said means for forcing comprises pump means communicating with said reservoir and said compartment for withdrawing water from the reservoir and forcing it under pressure beween substantially 8-10 atmospheres via said compartment into said chamber.
Claim 7
Dependent Claim
23 words
A machine as defined in claim 5; and further comprising means for preventing backflow of water from said chamber into said heating means.
Claim 8
Dependent Claim
30 words
A machine as defined in claim 5; and further comprising pressure-relief means for relieving said compartment to said reservoir in the event pressure in the compartment exceeds a predetermined limit.
Claim 9
Dependent Claim
25 words
A machine as defined in claim 5; said heating means comprising an electric heater operative for heating water to a temperature of substantially 80°-90° C.
Claim 10
Dependent Claim
68 words
A machine as defined in claim 5; and further comprising control means operatively connected with said heating means and pump and including a control element movable between a rest position, a first operating position in which said heating means is engaged, and a second operating position in which said pump is energized and remains energized for as long as said control element is in said second operating position.
