Abstract

An appliance controller is provided comprising an appliance including demand response settings. The settings include threshold variables for determining a reaction of the appliance in response to reaching one or more threshold variables. The controller further comprises a signal from an associated utility to the appliance, wherein the appliance includes a controller in signal communication with the associated utility. The controller receives and processes the signal from the associated utility. The signal is converted and compared to the demand response threshold variables and the appliance is operated in one or more power consuming functions based on the comparison of the signal to the demand response variables.

Claims

1. An appliance controller for controlling an appliance, the controller comprising:

a memory in communication with a processor, the memory including program instructions for execution by the processor to;

receive demand response settings from the appliance, the demand response settings comprising demand response threshold variables for determining a reaction of the appliance in response to reaching one or more of the demand response threshold variables;

receive a signal from an associated utility indicative of at least one of the demand response threshold variables, the controller being in signal communication with the associated utility;

convert and compare the signal from the associated utility to the demand response threshold variables; and

control an operation of the appliance in one or more power consuming functions based on the comparison of the signal from the associated utility to the demand response threshold variable, wherein the one or more power consuming functions comprise cycle selections comprising a reduced energy consumption mode to one or more energy cycles.

2. The appliance controller according to claim 1, wherein the demand response threshold variables are selected from the group consisting of cost of energy, carbon usage, maximum criticality level of demand, minimum criticality level of demand, total power consumption, and cost of power.

3. The appliance controller according to claim 1, wherein the one or more power consuming functions of the appliance and the controller are connected with a home energy management system (HEM).

4. The appliance controller according to claim 3, further comprising:

a demand response module for receiving signals from the HEM system, the demand response module comprising a USB interface for setting levels of the demand response threshold variables.

5. The appliance controller according to claim 3, further comprising:

a demand response module for receiving signals from the HEM system, the demand response module comprising a wireless module for receiving the signals.

6. The appliance controller according to claim 3, further comprising:

a demand response module for receiving signals from the HEM system, the demand response module comprising a power line carrier for receiving the signals.

7. The appliance controller according to claim 3, further comprising:

a demand response module for receiving signals from the HEM system, the demand response module comprising a web-based application for processing the received signals.

8. The appliance controller according to claim 3, wherein the processor is configured to:

pre-select an energy consumption maximum, wherein the one or more power consuming functions are dependent upon the pre-selected energy consumption maximum.

9. The appliance controller according to claim 3, wherein the processor is configured to:

pre-select a power consumption maximum wherein the one or more power consuming functions are dependent upon the pre-selected power consumption maximum.

10. The appliance controller according to claim 1, wherein the reaction of the appliance in the reduced energy consumption mode is based on a comparison of the signal indicative of at least one of the demand response threshold variables to the demand response settings.

11. The appliance controller according to claim 10, wherein the reaction of the appliance in the reduced energy consumption mode is based on user inputs regarding a desired elapsed completion time.

12. A method of controlling an appliance, the method comprising:

establishing demand response settings of the appliance, the demand response settings comprise demand response threshold variables for determining a reaction of the appliance responsive to reaching one or more of the demand response threshold variables;

connecting one or more power consuming functions with a home energy management system (HEM);

sending a signal indicative of at least one of the demand response threshold variables from an associated utility to the HEM, wherein the HEM includes a controller in signal communication with the associated utility;

the controller receiving and processing the signal indicative of the at least one of the demand response threshold variables from the associated utility;

converting and comparing the signal indicative of the at least one of the demand response threshold variables to the demand response settings; and

operating the appliance in the one or more power consuming functions based on the comparison of the signal to the demand response settings;

wherein the one or more power consuming functions comprises cycle selections comprising a reduced energy consumption mode to one or more energy cycles.

13. The method according to claim 12, wherein the demand response threshold variables are selected from the group consisting of cost of energy, carbon usage, maximum criticality level of demand, minimum criticality level of demand, total power consumption, and cost of power.

14. The method according to claim 12, further comprising:

receiving signals from the HEM controller in a demand response module, wherein receiving the signals includes receiving the signals in a USB interface for setting levels of the demand response settings.
