Benefits of technology

[0021] The apparatus of the present invention comprises a stationary outer tub, an inner washing basket having a basket wall, holes within the basket wall and an annular basket rim defining an open end to the washing basket. The inner washing basket is mounted for rotation within the stationary outer tub. A washing fluid is within the washing basket and a boot seal is attached to the outer tub. The boot seal is positioned closely adjacent the annular rim of the washing basket. A motor is adapted to rotate the washing basket at a tumble speed wherein the fabrics within the washing basket are tumbled but do not become plastered against the washing...

Problems solved by technology

If these fabrics are permitted to stay in this position during the spin cycle they will create friction against the stationary flexible boot seal and ultimately cause damage to the boot seal.

Embodiment Construction

[0025] Referring to the drawings, the numeral 10 generally designates a washing machine made according to the present invention. Washing machine 10 includes a cabinet 12 having a front door 14. The front door 14 includes a nose 16 which projects inwardly when the door is closed. The door is hinged to close over an access opening 18 having a boot seal 20 surrounding the access opening 18.

[0026] A detergent dispenser 22 is provided in the top of the washing machine 10 for introducing detergents and the like to the interior of the washing machine 10. Washing machine 10 also includes a control panel 24 having selector buttons 26, 28, 30, and 32. The control panel 24 also includes a control knob 34.

[0027] Mounted for rotation within the cabinet 12 is a wash basket 36 having holes 38 in its peripheral wall. Wash basket 36 also includes a plurality of fins or blades 40 protruding inwardly from its peripheral wall for tumbling the fabrics within the washing basket 36 during the time that ...

Abstract

The method of the present invention includes rotating the washing basket at a tumble speed insufficient to plaster the fabrics against the basket wall. The rotational speed is increased to a first plaster speed which causes the fabrics to be plastered against the basket wall. The plaster speed is increased to a second plaster speed higher than the first. Then the rotational speed of the washing basket is returned to the first plaster speed and the washing fluid is drained from the washing basket. The spin cycle is then begun. During the spin cycle a torque or speed sensor senses increased torque or reduced rotational speed of the washing basket caused by fabrics frictionally engaging the flexible boot during rotation of the washing basket at the spin speed. If such conditions are sensed, the spin cycle is terminated.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to the method and apparatus for spinning fabrics. [0002] Presently existing horizontal axis washing machines include a stationary tub which is mounted within a cabinet structure. Extending between the tub and an access opening within the cabinet is a flexible boot seal which is attached to both the cabinet and the stationary tub. Within the stationary tub is a washing basket that is mounted for rotation. The washing basket includes holes therein for permitting washing fluid to pass from the washing basket in an outward radial direction into the tub which surrounds it. [0003] The rotational axis of the washing basket is at an angle slightly elevated above horizontal. This results in the washing fluid within the basket residing in the lower rear portion of the washing basket. The washing basket includes a rim surrounding an access opening which is positioned closely adjacent to the flexible boot seal. [0004] During the w...
