Oven cooking control system with scanning display

Claim 2

In a cooking control system comprising an alphanumeric display, a keyboard having a plurality of data entry pads, and a programmed control system connected to said data entry pads and alphanumeric display for producing a timed control output for the operation of a microwave oven: the improvement wherein said data entry pads include a plurality of food entry pads each corresponding to a separate food type, said control means comprising means responsive to operation of said food entry pads for controlling said alphanumeric display to continually sequentially display the names of a plurality of different food items of the food type corresponding to the operated food entry pad, and to control the cessation of said sequential display in response to a further determined signal from said keyboard, said control means controlling the duration of said timed control output as a function of the food item displayed on said alphanumeric display at the time of said further determined signal.

Claim 3

The cooking control system of claim 1 wherein the name of each said food item of said plurality of food items is displayed for a period of 1 to 2 seconds during said continual sequential display.

Claim 4

The cooking control system of claim 1 wherein said control system comprises means for stopping said sequential display in response to release of the operated said food entry pad.

Claim 5

The cooking control system of claim 1 wherein said control means comprises means responsive to said cessation of said sequential display for displaying a prompt on said alphanumeric display for the quantity of food to be cooked.

Claim 6

The cooking control system of claim 4 wherein said control means further comprises means responsive to entry and said keyboard of a quantity, following the prompt quantity, for displaying on said alphanumeric display, a doneness/size prompt.

Claim 7

The cooking control system of claim 5 wherein said means for displaying said doneness/size prompt comprises means for sequentially displaying a plurality of doneness/size parameters on said alphanumeric display.

Claim 8

The cooking control system of claim 6 wherein said doneness/size prompt consists of sequentially displaying three different sequentially displayed items.

Claim 9

In a cooking control system comprising an alphanumeric display, a keyboard having a plurality of data entry pads, and a programmed control system connected to said data entry pads and alphanumeric display for producing a timed control output for the operation of a cooking control system: the improvement wherein said data entry pads include a plurality of food entry pads each corresponding to a separate food type, said control means comprising means responsive to operation of said food entry pads for controlling said alphanemeric display to continually sequentially display the names of a plurality of food items of the food type corresponding to the operated food entry pad, and to control the cessation of said sequential display in response to a further determined input from said keyboard, said control means further comprising means for receiving quantities from said data entry pads corresponding to the desired doneness or size, and quantity, of food items to be cooked, said control system further comprising means for providing an output control duration T, for energizing said cooking control system, of a duration: T=(M×Q×(1+K×D)+B)×(V) where M and B are linear equation constants dependent upon the selected food items, D is a constant that is a function of the selected food item determining the spread between the low and high doneness/size levels, K is a doneness/size integer which may be -1, 0 or +1, Q is a parameter dependent upon food quantity to be cooked, and V is a variable dependent upon the operating voltage of the cooking control system.

Claim 10

In a cooking control system comprising an alphanumeric display, a keyboard having a plurality of data entry pads, and a programmed control system connected to said data entry pads and alphanumeric display for producing a timed control output for the operation of a cooking control system: the improvement wherein said data entry pads include a plurality of food entry pads each corresponding to a separate food type, said control means comprising means responsive to operation of said food entry pads for controlling said alphanemeric display to continually sequentially display the names of a plurality of food items of the food type corresponding to the operated food entry pad, and to control the cessation of said sequential display in response to a further determined input from said keyboard, said control means further comprising means for receiving quantities from said data entry pads corresponding to the desired doneness or size, and quantity, of food items to be cooked, said control system further comprising means for providing an output control duration T, for energizing said cooking control system, of a duration: T=(M×Q×(1+K×D)+B)×(V) where M and B are linear equation constants dependent upon the selected food items, D is a constant that is a function of the selected food item determining the spread between the low and high doneness/size levels, K is a doneness/size integer which may be -1, 0 or +1, Q is a parameter dependent upon food quantity to be cooked, and V is a variable dependent upon the operating voltage of the cooking control system.
