Abstract

A microwave oven control utilizing a microcomputer. The control permits changing or adding to previously inputted parameters without requiring the cancellation of the entire program and without affecting the progression of other cycles of the program. In the illustrated embodiment, the control provides for facilitated initial input and changing of parameters, such as time, temperature, power; and the like, relative to different commands or functions inputted by suitable touch pads provided in a control panel for actuation by the user.

Claims

1. In a microwave oven having means defining an oven cavity and heating means for effecting microwave energy heating of matter in said oven cavity, the improvement comprising

control means for providing selectively different programs of operation of said heating means, said programs having different cycles of operation therein, and including means for changing the selection of cycles including addition and elimination of subsequent cycles and changing the parameters of any cycles of operation during continued running of a presently running cycle of a selected program.

2. The microwave oven structure of claim 1 wherein said control means includes selectively operable first input elements.

3. The microwave oven structure of claim 1 further including means for selectively cancelling the entire selected program during running thereof.

4. The microwave oven structure of claim 1 wherein at least one of the cycle of operation requires no input of parameters.

5. The microwave oven structure of claim 1 wherein said control means includes a manually operable touch pad input means for use in selecting said cycles.

6. The microwave oven structure of claim 1 wherein one of said cycles comprises a cycle of cooking to a selected temperature.

7. The microwave oven structure of claim 1 wherein one of said cycles comprises a "Keep Warm" cycle effecting said microwave energy heating of matter at a five percent power level.

8. The microwav,e oven structure of claim 1 wherein one of said cycles comprises a cycle of de-energization of the heating means prior to a cycle of further energization thereof.
