Abstract
A washing appliance includes a spinner basket having a curved labyrinth ring around its outer surface. The labyrinth ring blocks water from leaving the spinner basket during the washing cycle wherein the basket spins in a first direction. The labyrinth ring permits water to exit the spinner basket when it is rotating in the opposite direction during its spinning cycle.
Claims8
A washing appliance comprising:
- a spinner basket defining a basket cavity for holding a quantity of water and being mounted within said appliance for rotation about a non vertical spinner axis
- said spinner basket having a curved labyrinth ring extending around the outside of said spinner basket and positioned to rotate around said spinner axis when said spinner basket is rotating;
- said labyrinth ring having a plurality of elongated curved labyrinths therein;
- each of said labyrinths having a first end provided with an inlet opening providing communication from said basket cavity into said labyrinth and an opposite second end with an outlet opening providing communication from said labyrinth to the exterior of said spinner basket;
- drive mechanism connected to said spinner basket for rotating said spinner basket in a first rotational direction with said inlet openings trailing said outlet openings of each of said labyrinths, whereby said quantity of water does not exit said outlet openings of said labyrinth;
- said drive mechanism being capable of rotating said spinner basket in a second direction opposite from said first direction, whereby said quantity of water enters each of said labyrinths through said inlet openings and exits each of said labyrinths through said outlet openings to the exterior of said spinner basket.

A washing appliance comprising:
- a washing appliance cabinet;
- a spinner basket mounted within said appliance cabinet for rotation about a non vertical spinner axis;
- said spinner basket having walls defining a spinner cavity, a plurality of water drain holes in said walls of said spinner basket and being positioned in a circular line extending around said spinner axis, said spinner basket walls being free from water drain holes other that those in said circular line;
- a labyrinth ring surrounding said spinner basket and registered with said circular line of said water drain holes;
- said labyrinth ring having a plurality of labyrinths therein, each of said labyrinths being in communication with one of said water drain holes and having an exit opening spaced a predetermined distance from said one water drain hole;
- a water drain being in communication with said exit openings of said labyrinth ring for receiving water therefrom and draining said water from said appliance;
- said labyrinth ring blocking the exit of water from said spinner basket when said spinner basket rotates in a first rotational direction and permitting the exit of water from said spinner basket into said drain when said spinner basket rotates in a second rotational direction opposite from said first rotational direction.

A method for washing and spin drying fabrics comprising:
- placing a quantity of water within a spinner basket adapted to rotate about a non vertical axis, said spinner basket having a labyrinth ring extending around the exterior thereof, said labyrinth ring having a plurality of labyrinths therein, each of said labyrinths having an inlet opening providing communication into the interior of said spinner basket, and an outlet opening providing communication from said labyrinth to the exterior of spinner basket;
- placing said fabrics within said spinner basket;
- rotating said spinner basket in a first direction for tumbling and washing said fabrics;
- using said labyrinth ring to block the exit of said quantity of water from said spinner basket during said rotation of said spinner basket in said first rotational direction;
- reversing the rotational direction of said spinner basket to a second rotational direction opposite from said first rotational direction;
- using said labyrinth ring to permit said quantity of water to exit said spinner basket during said reversed rotation of said spinner basket in said second rotational direction.
