Abstract

A coffee brewing machine utilizes a microprocessor controller and, preferably, preformed coffee filter packs in which the filter packs form a rectangular array. The microprocessor controller regulates the temperature of the prepared coffee in the reservoir at the base of the machine, the operation of the water distributor in the swingable lid or cover of the machine and of other operating conditions thereof.

Claims

1. A coffee-making machine, comprising:

a source of hot water;

brewing means connectable to said source and having at least one brewing compartment and adapted to receive a quantity of ground coffee brewable to form a coffee beverage;

a plurality of receptacles adapted to receive coffee beverage;

electrically operable distributor means interposed between said brewing means and said receptacles for selectively connecting said brewing means with a respective one of said receptacles to deliver the coffee beverage to said receptacles; and

electrical control circuit means operatively connected to said distributor means for selectively connecting said distributor means with said receptacles.

2. The coffee-making machine defined in claim 1 wherein said electrical control circuit means includes a microprocessor operatively connected to said distributor means, and means for energizing said microprocessor to effectuate a program selectively connecting said distributor means automatically with said receptacles.

3. The coffee-making machine defined in claim 1 wherein said brewing means comprises a plurality of brewing compartments, each adapted to receive a respective filter.

4. The coffee-making machine defined in claim 3 wherein said filters form part of a replaceable multicompartment filter unit prepackaged with quantities of ground coffee.

5. The coffee-making machine defined in claim 3 wherein said filters form parts of respective replaceable filter units, at least one of said units having filters thereof prepackaged with quantities of ground coffee.

6. A filter unit for use in a coffee-making machine, comprising:

a support;

a plurality of filters formed on said support and defining respective brewing compartments; and

a respective premeasured quantity of ground coffee received in each of said compartments for the brewing of a respective quantity of coffee therewith, said unit forming a package provided with machine-readable indicia representing a quantity of infusion substance per filter.

7. The filter unit defined in claim 6 wherein a cover is provided over said compartments and is formed with respective openings communicating with said compartments for delivering hot water thereto.

8. The filter unit defined in claim 6 wherein said support is generally rectangular and said filters are arrayed in a plurality of parallel rows.

9. The filter unit defined in claim 6 wherein said support is composed of a disposable material enabling said unit to be replaced in a coffee-making machine and to be discarded.

10. The filter unit defined in claim 6 wherein said unit has an array of horizontally spaced apart outlets.

11. The filter unit defined in claim 6 wherein said indicia is a bar code.
