摘要： An automatic washer having an improved recirculation system wherein wash liquid is collected in a sump and recirculated onto the clothes load in a first recirculation loop and wash liquid is recirculated from a mixing tank through conduits and a pump back to the mixing tank to effect thorough mixing of the wash liquid. The mixing tank can be selectively connected to the first recirculation loop to direct selected amounts of wash fluid into the wash load, and a sensor is provided to sense the amount of wash fluid in the sump to assure that a sufficient amount of wash fluid is being recirculated into the clothes load.

摘要： In an automatic washing, a wash additive dispenser is disposed in a tub, and a drive mechanism is provided for selectively rotating the dispenser at a first angular speed and a second, greater angular speed. The wash additive fluid dispenser may be mounted on an agitator. The dispenser includes first passages for permitting liquid flow from the dispenser into the tub when the dispenser is rotated at least as fast the first angular speed, and second passages for permitting liquid flow from the dispenser into the tub when the dispenser is rotated as least as fast as the second angular speed. The dispensing cup can include a frutoconical portion having a sidewall diverging upwardly and terminating in a radially outwardly-extending toroidal portion disposed at the upper end of the frustoconical portion. A method of dispensing wash additive fluid is disclosed which includes the steps of retaining wash additive fluid in the dispenser during agitation, and centrifugally dispensing wash additive fluid into the tub from dispensing passages in the dispenser wall during at least one spin cycle. The method may include the substeps of centrifugally dispensing a first portion of wash additive fluid into the tub during a first spin cycle, and centrifugally dispensing a second portion of wash additive fluid into the tub during a second spin cycle.

摘要： A method for rinsing a textile wash load is provided for use in a vertical axis washing machine in which a plurality of initial spray rinses are used in which the released water is discharged directly to drain and a plurality of subsequent spray rinses are used in which the water is recirculated through the spinning clothes load for a predetermined length of time before being discharged to drain. Enhanced detergent and soil removal with less water usage is achieved with this method.
