First Claim
Patent Images
1. A method for measuring energy usage in an appliance, comprising:
- providing an AC-DC converter configured to receive an alternating current input voltage and to produce a high voltage direct current voltage;
providing an inverter configured to receive the high voltage direct current produced by the AC-DC converter and to provide a controllably variable alternating current output voltage;
providing a controller configured to provide inverter controlling signals to the inverter and to receive energy consumption related signals based at least in part on energy usage of the inverter;
providing a display coupled to the controller; and
configuring the controller to calculate real time power consumption and to cause the calculated results to be displayed on the display.

Abstract
The present subject matter relates to methods and apparatus for measuring energy usage in an appliance, particularly a washing appliance. A display, that may be a home energy monitor, is associated with the appliance. The appliance may include an AC-DC power supply and a controllable inverter configured to supply power to a motor associated with the appliance. Real power consumption is calculated by a controller that may also be used to control the inverter and other operational aspects of the appliance and causes the calculated real power to be displayed on the display.
