Energy management of dishwasher appliance
First Claim
1. A control method for a dishwasher, comprising:
- receiving an energy signal from an associated energy supplying utility;
from the energy signal, determining a state of the associated energy supplying utility, the state being indicative of at least peak and off-peak demand periods;
operating the dishwasher in a normal mode during a determined off-peak demand period;
operating the dishwasher in an energy savings mode during a determined peak demand period by determining a logical stopping point between consecutive operating cycles and advancing through one or more operating cycles until the logical stopping point is reached, wherein the logical stopping point is based on a desired balance between (i) dishwasher performance and (ii) cost savings/energy savings, and when the logical stopping point is determined, selectively deactivating at least one active power consuming function of the dishwasher to prevent the dishwasher from running a next operating cycle in the energy savings mode; and
returning to the normal mode after the peak demand period is over.

Abstract
A dishwasher is provided comprising one or more power consuming functions and a controller in signal communication with an associated utility. The controller can receive and process a signal from the associated utility indicative of current cost of supplied energy. The controller operates the dishwasher in one of a normal operating mode and an energy savings mode based on the received signal. The controller is configured to change the power consuming functions by adjusting one or more of an operation schedule, an operation delay, an operation adjustment, and a selective deactivation of at least one of the one or more power consuming functions to reduce power consumption of the dishwasher in the energy savings mode.
