SYSTEM FOR APPLIANCE AUTO RESTART AFTER A POWER SUPPLY LINE INTERRUPT
A system and method for restarting an appliance after a power supply interruption. A controller regularly communicates an operating status of the appliance and a power supply to a server which can send a restart command after a power supply interruption. The restart command is only communicated if the interrupt time was less than a time predetermined to be safe for restarting the appliance. Upon receiving the restart command, the controller restarts the appliance according to its most recently communicated operating status.
1 . An appliance with auto restart capability, the appliance comprising a controller configured to:
communicate an operating status of the appliance and a power supply status to a server in regular intervals;
restart the appliance after a power supply line interrupt responsive to a restart command from the server; and
operate the appliance based at least in part on the operating status most recently communicated to the server,
wherein the restart command is only received when a power supply line interrupt time is less than a predetermined time that indicates that the power supply line interrupt occurred due to a brief power outage.
2 . The appliance of claim 1 , wherein the appliance further comprises an internal power supply, the internal power supply configured to operate the appliance when the power supply line interrupt time is less than 0.6 seconds.
3 . The appliance of claim 2 , wherein the internal power supply is one or more capacitors.
4 . The appliance of claim 1 , wherein the power supply status is measured at a main circuit breaker.
5 . The appliance of claim 1 , wherein the power supply status is measured by a whole home meter.
6 . The appliance of claim 1 , wherein the appliance is a cooking oven and the operating status includes a cooking time or a cooking temperature.
7 . The appliance of claim 1 , wherein the appliance is a washing machine appliance and the operating status includes a wash time and a wash cycle.
8 . A method of restarting an appliance after a power loss event, the method comprising:
periodically communicating an operating status of the appliance and a power supply status prior to the power loss event for storage on a server;
receiving from the server a command to restart the appliance after the power loss event; and
restarting the appliance based at least in part on the operating status most recently stored on the server,
wherein the command to restart is received only if a duration of the power loss event was less than a predetermined duration.
9 . The method of claim 8 , wherein the appliance further comprises an internal power supply, the internal power supply configured to operate the appliance when the power loss event is less than 0.6 seconds.
10 . The method of claim 9 , wherein the internal power supply is one or more capacitors.
11 . The method of claim 8 , wherein the power supply status is measured at a main circuit breaker.
12 . The method of claim 8 , wherein the power supply status is measured by a whole home meter.
13 . The method of claim 8 , wherein the appliance is a cooking oven and the operating status includes a cooking time or a cooking temperature.
14 . The method of claim 8 , wherein the appliance is a washing machine appliance and the operating status includes a wash time and a wash cycle.
15 . A system for automatically restarting a cooking appliance after a power outage, the system comprising:
a remote server for storing an operating status of the cooking appliance and a power supply status for the appliance;
a cabinet defining a cooking chamber, the cooking chamber configured for receipt of food items to be cooked;
a heating assembly comprising a heating element disposed within the cooking chamber; and
a controller configured to:
receive a user input of a selected cooking cycle;
operate the heating assembly to cook the food items according to the selected cooking cycle;
periodically communicate an operational status of the selected cooking cycle to the remote server; and
restart the heating assembly after the power outage responsive to a restart command from the remote server to complete the cooking cycle.
16 . The system of claim 15 , wherein the appliance further comprises an internal power supply, the internal power supply configured to operate the appliance when the power outage time is less than 0.6 seconds.
17 . The system of claim 16 , wherein the internal power supply is one or more capacitors.
18 . The system of claim 15 , wherein the power supply status is measured at a main circuit breaker.
19 . The system of claim 15 , wherein the power supply status is measured by a whole home meter.
20 . The system of claim 15 , wherein the cooking cycle comprises a cooking temperature profile and a cooking time.
