摘要:
An automatic washer having an imperforate wash tub, a perforate wash basket disposed within the tub and rotatable about a vertical axis and a bottom plate disposed within the lower portion of the wash basket and mounted for wobbling motion. A motor 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, disposed in the bottom of the tub, through a recirculation line and onto and through the clothes disposed within basket.

A method of washing clothes in an automatic washer having an imperforate wash tub, a perforate wash basket disposed within the tub and rotatable about a vertical axis and a bottom plate disposed within the lower portion of the wash basket and mounted for wobbling motion. The method of operation of the washer includes loading the clothes into the wash basket, adding water and detergent into the tub for forming wash liquid, recirculating the wash liquid over the clothes while driving the bottom plate in a nutating movement. Nutating movement describes the movement of the bottom plate wherein the bottom plate is slowly rotated within the wash basket while being driven in a rapid wobbling motion. In this fashion, the clothes are repeatedly moved under a spray pattern of wash liquid while being jostled and flexed for achieving he desired excellent soil removal.

A method of rinsing in an automatic washer having an imperforate wash tub, a perforate wash basket disposed within the tub and rotatable about a vertical axis and a bottom plate disposed within the lower portion of the wash basket and mounted for wobbling motion. The method of rinsing includes adding rinse liquid into the wash basket and recirculating the rinse liquid over the clothes items while driving the bottom plate in a nutating movement. Nutating movement describes the movement of the bottom plate wherein the bottom plate is slowly rotated within the wash basket while being driven in a rapid wobbling motion. In this fashion, the clothes are repeatedly moved under a spray pattern of rinse liquid while being jostled and flexed for achieving the desired excellent detergent and soil removal during rinse. In a second embodiment, the step of slowly rotating the wash basket for moving the clothes under a spray pattern of rinse liquid is combined with a step of wobbling the bottom plate for agitating the clothes while spraying rinse liquid onto the clothes items.

An automatic washing machine comprises a spin tube coupled to the basket and an agitator shaft coupled to an agitator mounted in the basket. A motor coupled to the agitator shaft applies a torque the agitator shaft and thereby the agitator in first and second torque directions. A clutch couples the spin tube to the agitator shaft for cooperative rotation of the basket and the agitator regardless of the rotational direction of the agitator shaft. Because of the dual directionality of the clutch, reversing the motor simultaneously dynamically brakes the basket and the agitator, thereby eliminating the need for a separate friction brake for the basket.

A pump assembly supportable in a tank having an opening includes a pump such as a grinder pump and a cover attachable to the pump. The cover has a peripherally-extending portion extending outwardly from the pump and the peripherally-extending portion is sized to rest on a first surface of the portion of the tank defining the opening. A quick-release latching mechanism may include a plurality of members such as arms or pawls which are movable generally radially between a retracted position wherein the outer ends of the plurality of members are disposed inwardly of the peripherally-extending portion of the cover allowing the pump assembly to be lowered into the opening in the tank, and an extended position wherein the outer ends of a plurality of members are positionable against a second opposite side of the portion of the tank defining the opening to compress the portion of the tank forming the opening between the cover and the plurality of members.

A material handling vehicle includes first and second control handles positioned at opposing ends of an operator compartment. The first control handle is positioned adjacent the forks for driving the vehicle in a fore or forks first direction, and the second control handle is positioned adjacent the back of the vehicle for driving the vehicle in the aft or forks trailing direction. The control handles provide stability for the operator and an intuitive operator interface irrespective of direction of travel.

In a combination appliance comprising a dryer mounted above an automatic washer wherein access to the basket of the washer is limited, the basket of the washer tilts forward automatically to improve access as the lid is opened by the user. The basket is located within a tub that in turn is mounted on a resiliently supported frame. A cable connected between the lid and a lower portion of the rear of the tub is maintained in tension by a pulley that is spring-mounted to the interior of the cabinet. As the lid is opened, the cable is pulled along the pulley to tilt the basket forward on the resiliently supported frame for improved access by the user to the interior of the basket.

A vacuum cleaner includes a device which senses brush speed while varying nozzle height settings until an optimum height setting is reached. Nozzle height is varied by a motor that rotates a cam to move a support roller and is set by stopping the motor when a predetermined brush speed condition is reached. A programmed control circuit senses the brush speed while controlling the cam motor.
