Abstract

An appliance and a power cord assembly for providing electrical power to the appliance are provided. A plug receptacle is positioned on the appliance cabinet which includes two hot prongs, a neutral prong, and a ground prong. A power cord extends between an appliance plug and a wall plug, the wall plug being coupled to either a three prong or four prong outlet. The appliance plug includes four terminals complementary to the plug receptacle, with the neutral terminal and the ground terminal being electrically coupled within the appliance plug if the power cord has three wires.

First claim

What is claimed is:

1. An appliance comprising:
a cabinet;
a plug receptacle positioned on the cabinet, the plug receptacle including a first hot prong, a second hot prong, a neutral prong, and a ground prong, the plug receptacle being configured for receiving an appliance plug; and
a power cord that extends between a wall plug and the appliance plug, the appliance plug comprising a first hot terminal, a second hot terminal, a neutral terminal, and a ground terminal, wherein the neutral terminal and the ground terminal are electrically coupled by a jumper strap positioned within the appliance plug if the power cord has three wires;
wherein the neutral terminal and the ground terminal are electrically decoupled if the power cord has four wires.

2. The appliance of claim 1 , wherein the plug receptacle and the appliance plug define at least one keyed feature for properly aligning the appliance plug on the plug receptacle.

3. The appliance of claim 1 , wherein the first hot prong, the second hot prong, the neutral prong, and the ground prong are pins or blades that extend from the plug receptacle.

4. The appliance of claim 1 , wherein the plug receptacle is recessed within the cabinet.

5. The appliance of claim 1 , wherein the appliance plug defines a mating feature and the plug receptacle defines complementary feature for receiving the mating feature of the appliance plug.

6. The appliance of claim 1 , wherein the first hot terminal and the second hot terminal each have an electric potential of 120V relative to the ground terminal and 240V relative to each other.

7. The appliance of claim 1 , wherein the appliance is an electric dryer or an oven appliance.

8. A power cord assembly for an appliance, the power cord assembly comprising:
a plug receptacle positioned on the appliance, the plug receptacle including a first hot prong, a second hot prong, a neutral prong, and a ground prong, the plug receptacle being configured for receiving an appliance plug; and
a power cord that extends between a wall plug and the appliance plug, the appliance plug comprising a first hot terminal, a second hot terminal, a neutral terminal, and a ground terminal, wherein the neutral terminal and the ground terminal are electrically coupled by a jumper st rap positioned within the appliance plug if the power cord has three wire,
wherein the neutral terminal and the ground terminal are electrically decoupled if the power cord has four wires.

9. The power cord assembly of claim 8 , wherein the plug receptacle and the appliance plug define at least one keyed feature for properly aligning the appliance plug on the plug receptacle.

10. The power cord assembly of claim 8 , wherein the first hot prong, the second hot prong, the neutral prong, and the ground prong are pins or blades that extend from the plug receptacle.

11. The power cord assembly of claim 8 , wherein the plug receptacle is recessed within a cabinet of the appliance.

12. The power cord assembly of claim 8 , wherein the appliance plug defines a mating feature and the plug receptacle defines complementary feature for receiving the mating feature of the appliance plug.

13. The power cord assembly of claim 8 , wherein the first hot terminal and the second hot terminal each have an electric potential of 120V relative to the ground terminal and 240V relative to each other.

14. The power cord assembly of claim 8 , wherein the appliance is an electric dryer or an oven appliance.

15. A power cord for an appliance, the appliance comprising a cabinet and a plug receptacle including a first hot prong, a second hot prong, a neutral prong, and a ground prong, the power cord comprising:
a wall plug having a first hot terminal, a second hot terminal, and a neutral terminal;
an appliance plug configured for receipt within the plug receptacle, the appliance plug comprising a first hot terminal, a second hot terminal, a neutral terminal, and a ground terminal, wherein the neutral terminal and the ground terminal are electrically coupled by a jumper strap positioned within the appliance plug; and
a wire assembly extending between the wall plug and the appliance plug, the wire assembly comprising a first hot wire, a second hot wire, and a neutral wire.

16. The power cord of claim 15 , wherein the plug receptacle and the appliance plug define at least one keyed feature for properly aligning the appliance plug on the plug receptacle.

17. The power cord of claim 15 , wherein the appliance plug defines a mating feature and the plug receptacle defines complementary feature for receiving the mating feature of the appliance plug.

18. The power cord of claim 15 , wherein the first hot terminal and the second hot terminal each have an electric potential of 120V relative to the ground terminal and 240V relative to each other.
