Abstract
A cooking appliance includes an oven cavity, an electric heating element and a rapid cook heating system both of which being operable on either one of first and second supply voltages, and a controller including a memory module having stored therein first and second control algorithms. The controller will operate the cooking appliance based on one of the first or second control algorithm depending upon whether the cooking appliance is connected to the first or second supply voltages respectively. Preferably, the appliance includes a sensor for signaling the controller as to the presence of either the first or second supply voltage. In the alternative, the appliance can be manually set for use with a particular voltage supply.
Claims24
A cooking appliance comprising:
- an oven cavity including top, bottom, rear and opposing side walls;
- an electric heating element for heating the oven cavity during at least a portion of a cooking process, said electric heating element being operable on at least first and second supply voltages;
- a rapid cook heating source;
- and
- a controller including a memory module having stored therein first and second control algorithms, wherein the controller operates at least one of the electric heating element and rapid cook heating source in accordance with the first control algorithm when the appliance is connected to the first supply voltage and in accordance with the second control algorithm when the appliance is connected to the second supply voltage, with said first and second control algorithms establishing differing duty cycles and cycle times for the at least one of the electric heating element and rapid cook heating source in dependence upon an available supply voltage.
A cooking appliance comprising:
- an oven cavity;
- a radiant heating element arranged for producing radiant heat in the oven cavity;
- a rapid cook heating source;
- a control panel for inputting control parameters for a desired cooking operation;
- voltage selector means for establishing a permissible operating mode base on an input voltage available to the cooking appliance;
- and
- means for controlling the radiant heat element and the rapid cook heating source, said controlling means functioning to alter at least one of a duty cycle and a cycle time of at least one of the radiant heating element and the rapid cook heating source in dependence on the permissible operating mode.
A method of operating a cooking appliance including an oven cavity, an electric heating element and a rapid cook heating system which are operable on either one of first and second supply voltages for heating the oven cavity, and a controller having a memory comprising:
- connecting the cooking appliance to one of the first or second supply voltages;
- inputting to the controller which of the first and second supply voltages the appliance is connected;
- and
- operating at least one of the electric heating element and the rapid cook heating source in accordance with a first control algorithm stored in the memory when the cooking appliance is connected to the first supply voltage and in accordance with a second control algorithm stored in the memory when the cooking appliance is connected to the second supply voltage, with said first and second control algorithms establishing differing duty cycles and cycle times for the at least one of the electric heating element and rapid cook heating source in dependence upon an available supply voltage.
