Abstract

An energy management system for an appliance comprising an interface to receive a schedule having an off-peak time segment and an on-peak time segment; a control to determine an operation to be performed by the appliance; a mode selecting device to select between an energy management mode and an immediate start mode; and a controller connected to the interface, the control, and the mode selecting device. The controller is arranged such that upon selection of the energy management mode, the controller initiates the operation when a majority of the energy consumption of the operation is within the off-peak time segment; and upon selection of the immediate start mode, the controller initiates the operation immediately.

Claims

1. A method for managing energy usage of an appliance comprising:

receiving a schedule having an off-peak time segment and an on-peak time segment;

storing the schedule in a memory;

determining a current time;

determining an operation that needs to be performed by the appliance;

initiating the operation if the current time is within the off-peak time segment;

determining if operation would be detrimentally affected if stopped for a duration and restarted at a later time;

if the current time changes to the on-peak time segment, selectively continuing the operation if the operation is detrimentally affected by stopping and restarting, or stopping the operation if not detrimentally affected by stopping and restarting; and

,

restarting the stopped operation during another off-peak time segment.

2. The method of claim 1 further comprising:

establishing a deadline for completing the operation; and

,

initiating the operation such that it is completed prior to the deadline.

3. The method of claim 1 wherein the step of receiving a schedule includes inputting the schedule via a user interface on the appliance.

4. The method of claim 3 wherein the step of storing the schedule includes storing the schedule in a memory located in the appliance.

5. The method of claim 1 wherein the step of determining an operation includes selecting an operation via a control panel on the appliance.

9. The energy management system of claim 1, wherein selecting the first operation includes a control panel on the appliance to select the first operation.

10. The energy management system of claim 9, wherein selecting the operation of the second appliance is initiated from the first appliance.

6. A method for managing energy usage of a plurality of appliances comprising:

receiving a schedule having an off-peak time segment and an on-peak time segment;

storing the schedule in a memory;

determining a current time;

determining a first operation of a first appliance that needs to be performed;

initiating the first operation if the current time is within the off-peak time segment;

determining if the first operation affects an operation of a second appliance; and

,

initiating the operation of the second appliance during at least a portion of the same off-peak time segment.

7. The energy management system of claim 6 wherein the operation of the second appliance includes heating of water.

8. The energy management system of claim 6 wherein the operation of the second appliance includes cooling of air.

11. The energy management system of claim 7, wherein selecting the operation of the second appliance is initiated from the first appliance.

12. The energy management system of claim 8, wherein selecting the operation of the second appliance is initiated from the first appliance.

13. The energy management system of claim 12, further comprising a time keeping mechanism for providing the current time wherein the time keeping mechanism is automatically updated.

14. The energy management system of claim 13, wherein the first appliance is selected from the group consisting of a washing machine, a dishwasher, a clothes dryer, and an oven, and the second appliance is selected from the group consisting of a hot water heater and an air conditioner.

15. The energy management system of claim 6, wherein the first appliance is selected from the group consisting of a washing machine, a dishwasher, a clothes dryer, and an oven, and the second appliance is selected from the group consisting of a hot water heater and an air conditioner.

16. A method for managing energy usage of an appliance comprising:

receiving a schedule having an off-peak time segment and an on-peak time segment;

storing the schedule in a memory;

determining a current time;

determining an operation that needs to be performed by the appliance;

determining if the operation can be completed in the off peak time segment;

initiating the operation if the current time is within the off-peak time segment and the majority of the operation can be completed within the off-peak time segment; and

,

wherein the majority of the operation is based on the majority of the energy consumption.

17. The method of claim 16, further comprising:

determining if operation would be detrimentally affected if stopped for a duration and restarted at a later time;

if the current time changes to the on-peak time segment, selectively continuing the operation if the operation is detrimentally affected by stopping and restarting, or stopping the operation if not detrimentally affected by stopping and restarting; and

,

restarting the stopped operation during another off-peak time segment.
