Abstract

A microcomputer-controlled, integrated cooking apparatus for automatically preparing culinary dishes. The constituent ingredients of a particular dish are loaded into a compartmentalized carousel, which is mounted on the cooking apparatus. The apparatus includes a memory for storing one or more recipe programs. The recipe program specifies schedules for dispensing the ingredients from the carousel into a cooking vessel, for heating the vessel (either covered or uncovered), and for stirring the contents of the vessel. These operations are performed automatically under control of the microcomputer.

Claims

1. Apparatus for automatically cooking a culinary preparation of prescribed ingredients according to a predetermined recipe comprising:

a cooking vessel;

dispensing means structured and arranged to hold and to dispense said ingredients into said vessel;

heating means for heating said vessel;

stirring means for stirring the contents of said vessel;

control means communicating with said dispensing means for controlling the dispensing of said ingredients therefrom according to a dispensing schedule predetermined by said recipe, said control means further communicating with said heating means for controlling the heating of said vessel according to a heating schedule predetermined by said recipe, and said control means further communicating with said stirring means for controlling the stirring of said contents according to a stirring schedule predetermined by said recipe;

means, responsive to said control means, for automatically closing said cooking vessel; and

memory means for storing control instruction according to said recipe.

2. In an apparatus for automatically cooking a culinary preparation of prescribed ingredients according to a predetermined recipe, including a cooking vessel, heating means for heating the vessel, dispensing means for holding and dispensing said ingredients into said vessel, and control means communicating with said dispensing means and with said heating means for controlling the dispensing of said ingredients and the heating of said vessel according to dispensing and heating schedules predetermined by said recipe, the improvement wherein

said dispensing means comprises:

a chamber-defining assembly mounted for rotation and formed with a plurality of chambers of first and second types, said first type for holding non-liquid ingredients and said second type for holding liquid ingredients; and

means, actuated by rotation of said chamber-defining assembly, for mechanically causing the contents of said chambers to be dispensed, in sequence, into said vessel; and

said apparatus further comprises means for rotating said chamber-defining assembly upon command from said control means.

3. The apparatus of claim 2 wherein said chamber-defining assembly includes demountable first and second means for defining a selectable number of said first and second types of chambers, respectively.

4. The apparatus of claim 3 wherein

said dispensing means defines a dispensing aperture over said vessel and each said chamber has an opening at the bottom thereof;

and

said means for rotating said chamber-defining assembly is operable upon command from said control means to bring the openings of said chambers sequentially into registration with said aperture at times specified by said dispensing schedule.

5. The apparatus of claim 4 wherein

said second type of chamber includes a stopper and means for biasing said stopper in a position closing the opening at the bottom of said chamber;

and

said dispensing means further comprises cam means responsive to rotational movement of said chamber-defining assembly for urging said stopper out of said opening when the respective chamber opening is in registration with said dispensing aperture.

6. In an apparatus for automatically cooking a culinary preparation of prescribed ingredients according to a predetermined recipe, including a cooking vessel, heating means for heating the vessel, dispensing means for holding and dispensing said ingredients into said vessel, agitation means for agitating the contents of said vessel, and control means communicating with said dispensing means, heating means, and agitation means for controlling the dispensing and agitation of said ingredients and the heating of said vessel according to dispensing, agitation, and heating schedules predetermined by said recipe, the improvement wherein

said cooking vessel is disposed in fixed relation with respect to said heating means;

and

said agitation means comprises a stirring member extending into said vessel and mounted for rotation about a vertical axis for stirring the contents of said vessel in a generally circular pattern; and

said apparatus further comprises means for rotating said stirring member upon command from said control means.

7. The apparatus of claim 6 wherein said means for rotating said stirring member is operable for bidirectional rotation of said stirring member.

8. The apparatus of claim 7, further comprising:

a lid for covering said cooking vessel, said lid being formed with a lid aperture through which said dispensing means dispenses ingredients into said vessel; and

a closure member sized to cover said lid aperture, said closure member being mounted for rotation about said vertical axis, and being rotated by said means for rotating said stirring member into position closing said lid aperture upon command from said control means.

9. The apparatus of claim 6 wherein said dispensing means comprises:

a chamber-defining assembly mounted for rotation and formed with a plurality of chambers therein of first and second types, said first type for holding non-liquid ingredients and said second type for holding liquid ingredients; and

means, actuated by rotation of said chamber-defining assembly for mechanically causing the contents of said chambers to be dispensed, in sequence, into said vessel; and

said apparatus further comprises means for rotating said chamber-defining assembly upon command from said control means.

10. The apparatus of claim 9 wherein said chamber-defining assembly includes demountable first and second means for defining a selectable number of said first and second types of chambers, respectively.

11. Apparatus suitable for use in a domestic kitchen for automatically cooking a culinary preparation of prescribed ingredients according to a predetermined recipe comprising:

a cooking vessel having substantially vertical walls;

heating means for heating said vessel;

dispensing means for holding and dispensing said ingredients into said vessel, said dispensing means comprising;

a chamber-defining assembly mounted for rotation and formed with a plurality of chambers therein of first and second types, said first type for holding non-liquid ingredients and said second type for holding liquid ingredients; and

means, actuated by rotation of said chamber-defining assembly, for mechanically causing the contents of said chambers to be dispensed, in sequence, into said vessel;

a housing having a lower portion for housing said heating means, whereby said vessel is maintained in heat transfer relation to said heating means, and an upper portion for supporting said chamber-defining assembly over said vessel;

a stirring member extending into said vessel and mounted for rotation about a vertical axis for stirring the contents of said vessel in a generally circular pattern;

a lid for covering said vessel, said lid being formed with a lid aperture through which said dispensing means dispenses ingredients into said vessel, and a closure member mounted for rotation about said vertical axis and sized to cover said lid aperture;

control means for controlling the heating of said vessel, the dispensing and stirring of said ingredients, and the covering and uncovering of said lid aperture according to heating, dispensing, stirring, and covering schedules predetermined by said recipe;

means for rotating said chamber-defining assembly upon command from said control means;

means for simultaneously rotating said stirring member and said closure member upon command from said control means according to said stirring and dispensing schedules; and

memory means for storing control instructions according to said recipe;

wherein said control means and said means for rotating are housed within said housing so as to form a compact, self-contained, integrated cooking apparatus.

12. The apparatus of claim 11 wherein said control means comprises a microprocessor and said apparatus further comprises manual key entry means communicating with said microprocessor for manually activating and deactivating said dispensing, heating, and stirring means and for manually setting a heating level and a heating time for said heating means, said microprocessor and said key entry means being housed within said housing.
