1. A cooking appliance comprising:
- an oven cavity;
at least one heating element positioned to direct heat into the oven cavity;
a door mounted for movement relative to the oven cavity for selectively closing the oven cavity;
a control panel including a plurality of input members for programming at least time and temperature parameters for a cooking operation in the oven cavity, a mode selector input member, and means for selecting the cooking operation to be performed in the oven cavity from various distinct cooking operations including convection, bake and broil cooking options; and
means for controlling said at least one heating element in;
a default mode, entered without using the mode selector input member, wherein the controlling means requires both time and temperature parameters to be input through the control panel in order to initiate the cooking operation; and
a bypass mode, entered via the mode selector input member, wherein the controlling means requires only a temperature parameter to be input through the control panel in order to initiate the cooking operation,wherein, in both the default and bypass modes, the controlling means only initiates the cooking operation after a cooking operation selection is made through the selecting means.

Abstract
A control system for a cooking appliance can operate in first or second modes of operation. In the first mode, a consumer is required to input both a temperature parameter and a time parameter before initiating a cooking operation. Once the cooking operation has completed, the control system operates the cooking appliance in a low temperature mode for a predetermined period. In this manner, a cooked food item is maintained at a reduced temperature so that the food item does not burn. In the second mode, the consumer can choose to bypass the required time input parameter so as to operate the cooking appliance based solely on the temperature parameter.

5. In a cooking appliance including an oven cavity, at least one heating element disposed inside said oven cavity, and a control panel having a plurality of input members for programming at least time and temperature parameters for a cooking operation into a control system, a method of performing the cooking operation comprising:
-
a) selecting the cooking operation to be performed in the oven cavity from various distinct cooking operations, including convection, bake and broil cooking options, wherein the cooking operation can only be initiated after a cooking operation selection is made; b) operating the cooking appliance in a default mode, entered without using a mode selector input member, by; selecting a temperature parameter for the cooking operation through the control panel; inputting a time parameter through the control panel, said time parameter establishing a duration for the cooking operation; and initiating the cooking operation in the default mode after both the temperature parameter and time parameter have been input to the control system; and c) operating the cooking appliance in a bypass mode by; activating the mode selector input member to bypass the default mode wherein, upon bypassing the default mode, input of a time parameter is not required and the control system can perform the cooking operating based only on a temperature parameter; inputting a temperature parameter for the cooking operation through the control panel; and initiating the cooking operation in the bypass mode after the temperature parameter has been input. - View Dependent Claims (6, 7, 8)
