发明名称 Automatic washing machine with spin drain flow channels and reservoir; wash action tub ramps and cycles
摘要 An automatic washing machine includes a wash basin having a plurality of apertures and an annular liquid reservoir formed at an upper portion of the basin. A plurality of flow channels are arranged around the exterior surface of the wash basin. The plurality of flow channels includes upward flow channels, configured for directing wash liquid extracted from the wash basin into the reservoir under centrifugal force generated in a spin cycle. The plurality of flow channels also includes downward flow channels configured for directing wash liquid from the reservoir to a central drain following the spin cycle. The arrangement avoids the need for an outer wash tub, and at the same time provides stabilization to the wash basin during high speed spins. In another aspect, the wash basin may include wash action ramps provided on a bottom surface of the wash basin and at an upper sidewall of the wash basin. The wash action ramps, in conjunction with a sequence of wash basin acceleration and deceleration cycles, induce an effective wash action, and circulation of the wash load, in lieu of a conventional central agitator.
