Apparatus and method for controlling the energy usage of an appliance
First Claim
Patent Images
1. A method of controlling an appliance during a cycle of operation being performed by the appliance, comprising:
- receiving a signal including at least one of an energy usage reduction request and energy cost data;
in response to the signal, determining a recovery cost as the energy cost of interrupting the cycle of operation and completing the cycle of operation at a later time;
determining a continued operation cost as the energy cost needed to continue the cycle of operation without interruption, including determining a normal operation cost, which is the cost of continuing the cycle of operation without interruption in a normal mode, and determining a reduced power operation cost, which is the cost of continuing the cycle of operation without interruption in a reduced power mode;
comparing the recovery cost to the continued operation cost, including comparing the recovery cost to the normal operation cost and comparing the recovery cost to the reduced power operation cost; and
if the recovery cost is less than the reduced power operation cost and the normal operation cost, interrupting the cycle of operation and if the recovery cost is equal to or greater than the reduced power operation cost and less than the normal operation cost, continuing the cycle of operation without interruption in the reduced power mode.

21. An appliance configured to perform a cycle of operation comprising:
-
a treating chamber for receiving an article for treatment according to the cycle of operation; and a controller configured to implement the cycle of operation on the article in the treating chamber, the controller comprising; a processor; and a non-transitory storage medium storing machine readable instructions that when executed by the processor causes the controller to at least; determine a recovery cost for the appliance as the energy cost of interrupting the cycle of operation and completing the cycle of operation at a later time, determine a continued operation cost as the energy cost needed to continue the cycle of operation without interruption, including determining a normal operation cost, which is the cost of continuing the cycle of operation without interruption in a normal mode, and determining a reduced power operation cost, which is the cost of continuing the cycle of operation without interruption in a reduced power mode; compare the recovery cost to the continued operation cost, including comparing the recovery cost to the normal operation cost and comparing the recovery cost to the reduced power operation cost; and if the recovery cost is less than the reduced power operation cost and the normal operation cost, interrupt the cycle of operation on the article in the treating chamber and if the recovery cost is equal to or greater than the reduced power operation cost and less than the normal operation cost, continuing the cycle of operation without interruption in the reduced power mode. - View Dependent Claims (22, 23, 24, 25)
