Abstract

A standby power system for an appliance having a power input coupled to a main power source includes a power enabling device coupled between the main power source and power input of the appliance, a standby power state sensing device coupled to the power enabling device, and a power restore device coupled to the power enabling device.

Claims

1. A standby power system for an appliance having a power input coupled to a main power source, comprising:

a power enabling device coupled between the main power source and the power input of the appliance;

a standby power state sensing device coupled to the power enabling device; and

a power restore device coupled to the power enabling device.

2. The standby power system of claim 1, wherein the power enabling device comprises a relay that electrically connects the power input of the appliance to the main power source in one state, and disconnects the power input of the appliance from the main power source in another state.

3. The standby power system of claim 1, wherein the power enabling device is configured to electrically disconnect the power input of the appliance from the main power source.

4. The standby power system of claim 1, wherein the standby power state sensing device is configured to detect a standby state and generate a standby power state signal and the power enabling device is responsive to said power state sensing device and operative in response to said signal to disconnect the power input of the appliance from the main power source.

5. The standby power system of claim 4, wherein the detected standby state comprises at least one of a user proximity to the appliance, elapsed time from last use, ambient light level, activity level, motion sensing, manual input, power management control input, energy management commands, time of day, user presets, control status sensing, intermodule communication.

6. The standby power system of claim 4, wherein the detected standby state comprises a sensed physical property of the appliance.

7. The standby power system of claim 6, wherein the sensed physical property comprises at least one of pressure, temperature, wind speed, wind direction, luminous intensity, sound.

8. The standby power system of claim 4, wherein the detected standby state comprises a randomized time event.

9. The standby power system of claim 1, wherein the power restore device comprises a switch that is configured to provide a power-on signal to the power enabling device to cause the power enabling device to automatically connect the main power source to the power input of the appliance.

10. The standby power system of claim 9, wherein the switch comprises a manually activated switch configured to provide the power-on signal to the power enabling device when activated.

11. The standby power system of claim 9, wherein the appliance further comprises:

at least one door; and

a door opening device coupled to each of the at least one door;

wherein the switch is coupled to the door opening device and is configured to generate the power-on signal when the door opening device is activated to open a respective door.

12. The standby power system of claim 9, wherein the appliance includes a body, and the switch is incorporated in the body of the appliance.

13. The standby power system of claim 1, further comprising a standby power source coupled to the appliance, the standby power source configured to provide electrical power to predetermined electrical components of the appliance in a standby state.

14. The standby power system of claim 13, wherein the switch is a touch sensitive switch or proximity sensor.

15. A power control system for an appliance, comprising:

a power input to the appliance;

an external source of electrical power;

a power enabling device coupled between the external source of electrical power and the power input to the appliance; and

a standby state sensing device coupled to the power enabling device and configured to detect an existence of a standby state trigger and transmit a standby state activation signal to the power enabling device.

16. The power control system of claim 15, wherein the power enabling device is configured to disconnect the external source of electrical power from the power input to the appliance when the standby state activation signal is detected.

17. The power control system of claim 15, further comprising a power restore device coupled to the power enabling device, the power restore device configured to provide a power restore signal to the power enabling device, wherein the power enabling device establishes an electrical connection between the external source of electrical power and the power input to the appliance.

18. The power control system of claim 17, wherein the power restore device is a manually activated switch or a signal triggered by a manual input setting.

19. The power control system of claim 16, further comprising a standby power source electrically connected to or within the appliance, the standby power source configured to provide a minimum source of electrical power to control components of the appliance when the standby state activation signal is detected and the power input to the appliance is disabled from the external source of electrical power.

20. The power control system of claim 19, wherein the standby power source comprises an energy storage device.
