Abstract

An electric cooking appliance operable from two 120 VAC household circuits. The electric cooking appliance includes a plurality of surface heating units and a pair of oven heating units operably coupled to two AC power sources. The oven heating units are coupled to one of the power sources through a thermostat and a switching circuit for alternately switching the heating units between a high bake, a high broil, and a dual bake/broil setting. A plurality of surface unit switches interposed between the power source and each surface unit controls the operation and current draw of the each surface unit.

Claims

1. An electrical cooking appliance for use with a first power source of approximately 120 volts and a second power source of approximately 120 volts without requiring a 240 volt power source, the electrical cooking appliance comprising:

a power supply circuit adapted to be connected to the first power source and the second power source, the power supply circuit having a first hot line for connecting to the first power source, a second hot line for connecting to the second power source, and a neutral line;

a plurality of surface heating units;

a pair of oven heating units;

wherein a first of the plurality of surface heating units and the pair of oven heating units are connected to the neutral line and the first hot line of the power supply circuit for supplying power from the first power source to the first surface heating unit and the pair of oven heating units; and

wherein the remaining surface heating units are connected to the neutral line and the second hot line of the power supply circuit for supplying power from the second power source to the remaining surface heating units.

2. The electrical cooking appliance of claim 1 further comprising a thermostat means operably coupled between the first power source and the oven heating units.

3. The electrical cooking appliance of claim 2 wherein the thermostat means further comprise an infinite heat control.

4. The electrical cooking appliance of claim 1 further comprising a plurality of switching means each operably coupled between the power supply circuit and a respective surface heating unit.

5. The electrical cooking appliance of claim 1 wherein each of the pair of oven heating units comprises dual coils, a first one of the pair of oven heating units comprising a broil heating unit and a second one of the pair of oven heating units comprising a bake heating unit, wherein one of the coils of each of the bake heating unit and the broil heating unit are supplied with power in a first cooking mode, one of the coils of the broil heating unit and both of the coils of the bake heating unit are supplied with power in a second cooking mode, and one of the coils of the bake heating unit and both of the coils of the broil heating unit are supplied with power in a third cooking mode.

6. The electrical cooking appliance of claim 5 wherein a toggle switch controls the selection of the first, second, and third cooking modes.

7. An electrical cooking appliance for use with a first power source of approximately 120 volts and a second power source of approximately 120 volts without requiring a 240 volt power source, the first power source being provided by an electrical power circuit of a building separate from an electrical power surface providing the second power source, the electrical cooking appliance comprising:

a power supply circuit adapted to be connected to the first power source and the second power source, the power supply circuit having a first hot line for connecting to the first power source, a second hot line for connecting to the second power source, and a neutral line;

a plurality of surface heating units;

a pair of oven heating units;

wherein a first of the plurality of surface heating units and the pair of oven heating units are connected to the neutral line and the first hot line of the power supply circuit for supplying power from the first power source to the first surface heating unit and the pair of oven heating units; and

wherein the remaining surface heating units are connected to the neutral line and the second hot line of the power supply circuit for supplying power from the second power source to the remaining surface heating units;

a thermostat means operably coupled between the first power source and the oven heating units, the thermostat means further comprising an infinite heat control;

a plurality of switching means each operably coupled between the power supply circuit and a respective surface heating unit;

wherein each of the pair of oven heating units comprises dual coils, a first one of the pair of oven heating units comprising a broil heating unit and a second one of the pair of oven heating units comprising a bake heating unit, wherein one of the coils of each of the bake heating unit and the broil heating unit are supplied with power in a first cooking mode, one of the coils of the broil heating unit and both of the coils of the bake heating unit are supplied with power in a second cooking mode, and one of the coils of the bake heating unit and both of the coils of the broil heating unit are supplied with power in a third cooking mode; and

wherein a toggle switch controls the selection of the first, second, and third cooking modes.
