  • Patent number: 10822735
    Abstract: A washing machine appliance includes a motor for selectively rotating a wash basket within a wash tub. A controller is configured for initiating a spin cycle by ramping up the speed of the wash basket to a target speed. The controller monitors a measured basket speed to determine whether the measured basket speed has reached a predetermined acceleration reference speed within an acceleration time limit or whether the measured basket speed has fallen below a dropout reference speed for a dropout time limit. If either condition exists, the controller adjusts the operation of the washing machine appliance, e.g., by reducing the wash basket speed to permit wash fluid entrained in the annulus to escape and reduce drag on the wash basket.

  • Patent number: 10344415
    Abstract: A method of washing fabric articles in a tunnel washer that includes moving the fabric articles from the intake of the washer to the discharge of the washer and through multiple modules or sectors. Liquid can be counter flowed in the washer interior along a flow path that is generally opposite the direction of travel of the fabric articles. A dual use zone includes multiple of the modules or sectors. In a dual use zone, a module or modules can be used to both wash and thereafter rinse the fabric articles. While counterflow rinsing, the flow rate can be maintained at a selected flow rate or flow pressure head. One or more booster pumps can optionally be employed to maintain constant counterflow rinsing flow rate or constant counterflow rinsing pressure head. During rinsing, extracted water or reuse water is first used to rinse followed by a clean water rinse.
