ADAPTIVE DRAIN ALGORITHM FOR CLOTHES WASHERS

摘要

This disclosure is related to a system and method which minimizes the period of time in which a drain pump is running in a washing machine uni t. The method includes determining the amount of washer fluid used to fill a washing machine tub when the washing machine has entered the draining portion of the cycle, measuring the time it takes in order to trip a water level sensor. The method generally continues with calculating a predicted time to drain and operating a drain pump according to the predicted time to drain. Use of this method minimizes the opportunities for machine malfunctions while further minimizing the opportunity for the pump to run dry, creating noise and increasing the length of the entire washing cycle.
