Tvättmaskin med vertikal axel

摘要

An automatic washer having an imperforate wash tub (34), a perforate wash basket (36) disposed within the tub and rotatable about a vertical axis and a bottom plate (80) disposed within the lower portion of the wash basket and mounted for wobbling motion. A motor (100) is selectively interconnected with the basket and bottom plate for rotating the basket and the bottom plate together and for wobbling the bottom plate relative to the wash basket while the basket is held stationary such that the clothes items are agitated within the wash basket. A controlled rotation device is provided for driving the bottom plate in a wobbling motion while rotating the bottom plate, at a reduced rate, within the bottom of the wash basket. In a second embodiment, the wobble plate is supported and constrained to be driven in a wobbling motion while experiencing no rotation within the basket. A liquid level control system is also provided for supplying an optimum quantity of wash liquid into the tub wherein the clothes items within the wash basket are washed in an out-of-water wash process rather than being submerged. A recirculation system operates to pump wash liquid from a sump (72), disposed in the bottom of the tub, through a recirculation line (74) and onto and through the clothes disposed within basket.
