Abstract

A cooking appliance includes a control panel which includes a rotary dial for selecting and entering control information to the cooking appliance, and a control interface for providing a prompt to guide a user through a selection process of the control information. The control information includes at least one of a cooking mode, a food type, a food weight or size, a cooking temperature, and a degree of doneness. The cooking appliance is operatively responsive to the selection of the control information from the rotary dial before and during cooking.

Claims

1. A control system for a cooking appliance for use in cooking, said control system comprising:

a control panel comprising at least one rotary dial input device configured to actively input entry of control information for said cooking appliance before and during cooking, said control information comprising at least one of a cooking mode, a food type, a food weight, a temperature, and a degree of doneness, said cooking appliance operatively responsive to said selection of said control information from said rotary dial; and

a control interface for providing a prompt to guide a user through selecting said control information, said control interface configured to interact with at least one cooking mode of said cooking appliance.

2. A control system in accordance with claim 1 wherein said rotary dial input device is configured to provide tactile feedback simultaneously as said rotary dial is rotated, said tactile feedback permits a user to determine an amount of rotation.

3. A control system in accordance with claim 2 wherein said tactile feedback comprises a resolution of approximately 15–

25 counts per complete revolution.

4. A control system in accordance with claim 3 wherein said select switch is engaged when said rotary dial input device applies pressure to said select switch.

5. A control system in accordance with claim 3 wherein said select switch is configured to input said control information displayed on said control interface to said cooking appliance after said rotary dial input device applies pressure to said select switch.

6. A control system in accordance with claim 2 wherein said rotary dial input device is mechanically coupled to a select switch.

7. A control system in accordance with claim 1 wherein said control information further comprises at least one of adjust or review.

8. A control system in accordance with claim 1 wherein said active input entry of control information includes adjusting a cooking time during said cooking.

9. A control system in accordance with claim 1 wherein said cooking appliance cooking mode comprises a microwave mode.

10. A control system in accordance with claim 1 wherein said cooking appliance cooking mode comprises a lightwave mode.

11. A control system for a cooking appliance for use in cooking, said control system comprising:

a control panel comprising at least one rotary dial input device configured to select control information for said cooking appliance, said control information comprising a cooking time, a cooking mode, a food type, a food weight, a temperature, and a degree of doneness, said cooking appliance operatively responsive to said selection of said control information from said rotary dial, said rotary dial input device configured to actively input entry of said cooking time for said cooking appliance before and during cooking; and

a select switch mechanically coupled to said rotary dial input device, said select switch configured to input said control information to said cooking appliance.

12. A control system in accordance with claim 11 further comprising a control interface for providing a prompt to guide a user through selecting control information, said control interface display configured to interact with various cooking modes of said cooking appliance.

13. A control system in accordance with claim 12 wherein said rotary dial input device is configured to provide tactile feedback simultaneously as said rotary dial is rotated, said tactile feedback permitting a user to determine an amount of rotation.

14. A control system in accordance with claim 13 wherein said tactile feedback comprises a resolution of approximately 15–

25 counts per complete revolution.

15. A control system in accordance with claim 11 wherein said select switch is engaged when pressure is applied to said select switch by said rotary dial input device.

16. A control system in accordance with claim 15 wherein said select switch is configured to input said control information to said cooking appliance after pressure is applied to said select switch.
