Abstract
An automatic liquid level control system is provided for a laundry appliance having a tub and a perforate fabric basket within the tub. Washing liquid is injected onto the surface of fabrics to be laundered. A portion of the washing liquid will be absorbed by the fabrics and a portion will flow through the fabrics and fabric basket perforations for accumulation in the tub. Sensing devices are provided for monitoring the changing liquid level in the tub and the time required to reach predetermined levels. A programmable controller determines the quantity of additional liquid required to launder the fabric load responsive to the sensing devices and commensurate with the load characteristics and controls the injection thereof onto the fabrics.
