  • Patent number: 10179963
    Abstract: A fabric treating appliance includes a rotatable basket defining a treating chamber for receiving a load of laundry items for treatment. A float valve can be incorporated into the basket structure, selectively opening or closing the valve based upon the liquid level in a tub. As liquid fills the tub, the float valve will rise until it moves into a closed position, permitting the basket and treating chamber to fill with liquid. As the tub drain, the float valve can fall, opening the valve and permitting liquid to drain from the basket or treating chamber. The opened or closed positions can be selectively operated by opening or closing a pump or sump and allowing a tub to drain or fill, respectively.

  • Patent number: 8490439
    Abstract: In a laundry washer, relatively short bursts of operation of a recirculation pump are coordinated with corresponding brief intervals of tub rotation during the initial fill periods. The aim is to thoroughly wet the clothes early in each wash/rinse phase to thus improve the wash/rinse effectiveness, while also avoiding excessive suds formation. Following the initial fill periods and during regular wash/rinse agitations, the recirculation system may also be employed to “recharge” the laundry load with detergent that has settled in the bottom of the tub. In a further aspect of the invention, some or all of the conventional intermediate spin extractions are omitted. In this manner, more water is carried over in the clothes from one wash/rinse cycle to the next. An intermediate spin of reduced speed (RPM) and duration as compared to typical normal intermediate spins may be employed between the wash phase and first rinse.
