Patent number: 8505139Abstract: A washer fill system and method supply a suitable minimum amount of water necessary to wash a particular load of laundry based on readings taken from a pressure sensor that measures liquid pressure in the wash tub. Pressure sensor readings are taken intermittently during the fill process to determine when a sufficient amount of free water for washing the load of clothes has accumulated in the tub. This includes pressure readings taken while pulsing the washer motor to spin the wash basket. Other pressure readings may be taken during a pause in filling to measure the water run-off from the wetted clothes above the free water line, and the release of air bubbles from a load portion below the water line. Determining the sufficiency of the amount of wash liquid in the wash tub involves implementation of an algorithm with coefficients determined through regression analyzes, and may include other factors.Type: GrantFiled: January 18, 2007Date of Patent: August 13, 2013Assignee: Electrolux Home Products, Inc.Inventors: Vicente Marconcin Vanhazebrouck, Marcos Paulo Soares Bittencourt, Marcelo Piekarski, David Irwin Ellingson, Jon Roepke
