Abstract

An appliance includes an appliance housing, an interface adapted to receive power information, a plurality of sensors for sensing environmental conditions, a plurality of controls for controlling operations of the appliance, and an intelligent control. The intelligent control is disposed within the appliance housing and operatively connected to the interface and the plurality of sensors and adapted to dynamically select control values associated with the plurality of controls based on at least one of the power information, the environmental conditions, or a combination thereof to increase energy efficiency of the appliance.

Claims

1. An appliance for use in an environment comprising:

an appliance housing;

an interface adapted to receive power information;

at least one sensor for sensing environmental conditions;

at least one control for controlling operations of the appliance;

an intelligent control disposed within the appliance housing and operatively connected to the interface and the at least one sensor and adapted to dynamically select at least one control value associated with the at least one control based on at least one of the power information, the environmental conditions, or a combination thereof to increase energy efficiency of the appliance.

2. The appliance of claim 1 wherein the interface is adapted to receive the power information from a smart grid.

3. The appliance of claim 1 wherein the appliance further comprises an onboard power meter and the interface is adapted to receive the power information from the onboard power meter.

4. The appliance of claim 1 wherein the intelligent control is further adapted to calculate or estimate environmental conditions based on data from the at least one sensor.

5. The appliance of claim 1 wherein the appliance includes a fan and the at least one control value includes a fan time delay.

6. The appliance of claim 1 wherein the appliance includes a compressor disposed within the appliance housing, the at least one control includes a compressor speed control and the at least one control value includes a compressor speed.

7. The appliance of claim 1 wherein the appliance includes a fan disposed within the appliance housing, the at least one control includes a fan control, and the at least one control value includes a fan time delay.

8. The appliance of claim 1 wherein the at least one sensor includes at least one of a temperature sensor for sensing ambient temperature, a humidity sensor for sensing humidity, a water hardness sensor, or a pH sensor.

9. The appliance of claim 1 wherein the appliance is a refrigerator and wherein the appliance housing is a refrigerator cabinet.

10. The appliance of claim 1 wherein the power information comprises at least one of power quality, load information, or energy consumption information.

11. The appliance of claim 1 further comprising a power meter operatively connected to the intelligent control.

12. A refrigerator for use in an environment comprising:

a refrigerator cabinet;

a compressor disposed within the refrigerator cabinet;

an interface adapted to receive power information;

at least one control for controlling the refrigerator;

an intelligent control disposed within the refrigerator cabinet and operatively connected to the interface and adapted to select at least one control value associated with the at least one control based on the power information to increase energy efficiency of the refrigerator.

13. The refrigerator of claim 12 wherein the interface is adapted to receive the power information from a smart grid.

14. The refrigerator of claim 12 further comprising a fan and the at least one control value includes a fan time delay.

15. The refrigerator of claim 12 wherein the at least one control includes a compressor speed control and the at least one control value includes a compressor speed.

16. The refrigerator of claim 12 wherein the refrigerator includes a fan disposed within the refrigerator housing, the at least one control includes a fan control, and the control values include a fan time delay.

17. The refrigerator of claim 12 further comprising at least one environmental sensor.

18. An appliance for use in an environment comprising:

an appliance housing;

an interface adapted to receive power information from a smart grid;

a sensor for sensing an environmental condition associated with the environment;

a control for controlling operation of the appliance;

an intelligent control disposed within the appliance housing and operatively connected to the interface and the sensor and adapted to select a control value associated with the control based on at least one of the power information, the environmental condition, or a combination thereof to increase energy efficiency of the appliance.

19. The appliance of claim 18 wherein the appliance is a refrigerator and wherein the appliance housing is a refrigerator cabinet.

20. The appliance of claim 19 wherein the sensor is from a set consisting of a temperature sensor for sensing ambient temperature, a humidity sensor for sensing humidity, a water hardness sensor for sensing water hardness, and a pH sensor for sensing pH.
