초록 ▼

The coffee brewing machine can be used to prepare alternatively normal coffee or espresso coffee and comprises a boiler having a temperature control. The cold water is fed to the boiler by a water pump with adjustable feed rate. Two different brewing members are used for the preparation of the two kind of coffees, namely a sieve holder and a filter support which are connectable via a mounting and supporting flange to the boiler. A mode switch is assigned to the mounting and supporting flange which automatically changes the mode of operation of the coffee brewing machine upon exchanging the brewing member. Thereby, the feed rate of the water pump and the temperature of the hot water are adapted to optimize the conditions for preparing either normal coffee or espresso coffee.

대표청구항 ▼

A coffee brewing machine for preparing espresso coffee in a first mode of operation when hot water is forced under pressure through a compressed cake of coffee powder and for preparing normal coffee in a second mode of operation when hot water runs without pressure through a filter containing coffee powder, said machine comprising: first brewing means including a sieve holder for receiving a compressed cake of coffee powder; second brewing means including a coffee filter support member for receiving a filter containing coffee powder; an electrically operable boiler for heating water including thermostat means for enabling adjustment of the temperature to which the water in said boiler is to be heated, said boiler being operable in (i) a first mode of operation in which cold fresh water is heated to a first lower temperature of about between 85°C. and 90°C., and (ii) a second mode of operation in which cold fresh water is heated to a second higher temperature of about 95°C.; supporting means connected to said boiler and to which said first and second brewing means can be connected alternatively; a container adapted to receive cold fresh water; a water pump having an adjustable feed rate and for feeding cold fresh water from said container to said boiler and therefrom to said supporting means, said water pump including feed rate adjusting means for enabling adjustment of the feed rate at which water through said water pump is to flow, said water pump being operable in (i) a first mode of operation in which said water pump feeds water to said boiler at a first higher feed rate, and (ii) a second mode of operation in which said water pump feeds water to said boiler at a second lower feed rate; a mode switch including a pin member axially displaceable between a first switching position corresponding to the first mode of operation of said machine to prepare espresso coffee and a second switching position corresponding to the second mode of operation of said machine to prepare normal coffee, said pin member being in said first switching position when said sieve holder of said first brewing means is connected to said supporting means, said pin member being in said second switching position when said coffee filter support member of said second brewing means is connected to said supporting means; and a control unit for (i) monitoring the position of said pin member of said mode switch, (ii) controlling said thermostat means to adjust the temperature of the water in said boiler, and (iii) controlling said feed rate adjusting means to adjust the feed rate of the water flow through said water pump; said control unit controlling said thermostat means to control the temperature of the water in said boiler and said feed rate adjusting means to control the feed rate of the water flow through said water pump in response to the position of said pin member of said mode switch, said water pump being in its first mode of operation in which said water pump feeds water from said container to said boiler at said first higher feed rate and said boiler being in its first mode of operation in which the water in said boiler is heated to said first lower temperature of about between 85°C. and 90°C. to thereby prepare espresso coffee when said pin member of said mode switch is in its first switching position corresponding to the first mode of operation of said machine, said water pump being in its second mode of operation in which said water pump feeds water from said container to said boiler at said second lower feed rate and said boiler being in its second mode of operation in which the water in said boiler is heated to said second higher temperature of about 95°C. to thereby prepare normal coffee when said pin member of said mode switch is in its second switching position corresponding to the second mode of operation of said machine.
