Abstract

A pair of laundry treating appliances having power sharing capabilities through a piggyback plug with a rear facing electric socket. The rear facing electric socket is designed to receive a power plug from a compatible laundry treating appliance. The piggyback plug is connected to a terminal block of one of the laundry treating appliance wherein the terminal block is adapted to be selectively connected to one of a 120V or 240V electric power source. A controller is adapted with an algorithm to prevent electrical overloading by automatically reducing the electrical power consumed by one of the appliance when simultaneous energization of both appliances occur.

First claim

What is claimed is:

1. A washing machine adapted to interoperate with a dryer, the washing machine comprising:
a laundry treating chamber;
a terminal block adapted to connect to a 240V power supply;
at least one heating element to provide heat to the laundry treating chamber;
an electrical circuit between the terminal block and the at least one heating element; and
a controller connected to the electrical circuit and configured to control cycles of operation of the washing machine and to communicate with the dryer;
wherein the controller is configured to switch operation of the washing machine between two power levels in response to operational characteristics of the dryer.

2. The washing machine of claim 1 wherein the controller is configured to switch operation of the washing machine between two power levels by energizing or de-energizing heating elements.

3. The washing machine of claim 2 wherein the controller has a communication module adapted to form a connection between the dryer and the washing machine and the controller is further configured to reduce power consumed by the dryer depending on a power usage of the washing machine.

4. The washing machine of claim 2 further comprising a power plug adapted to connect the washing machine to a generic electric receptacle.

5. The washing machine of claim 4 wherein the power plug is a piggyback power plug having a rear facing electric socket.

6. The washing machine of claim 5 wherein the piggyback power plug includes a cover member to protect the rear facing electric socket when not in use.

7. The washing machine of claim 6 wherein the cover member can be secured via a fastener.

8. The washing machine of claim 5 wherein the rear facing electric socket includes a unique power terminal layout configured to receive a compatible clothes dryer power plug.

9. The washing machine of claim 8 wherein the power plug is adapted to receive the compatible clothes dryer power plug to allow power sharing from a single power source.

10. The washing machine of claim 3 wherein the controller automatically reduces electrical power consumed by the washing machine when simultaneous energization of the washing machine and dryer occurs.
