초록 ▼

A method and control for an automatic washer is provided in which moisture extraction from a fabric load is controlled by extracting the moisture at increasingly faster levels of basket rotation. Initially the basket is rotated relatively slowly and it is subsequently rotated at successively faster speed levels, each increase occurring after substantially all of the moisture has been removed which is removable at a given speed level. Inertia of the fabric load is measured to determine the amount of incremental moisture removal. Use of such a method substantially reduces the force applied to the fabric load during the centrifugal extraction resulting in less wrinkling of the fabrics.

대표청구항 ▼

A method of extracting moisture from a fabric load in an automatic washer which has a rotatable wash basket comprising the steps: rotating said basket at a first, low rotational speed level until all of the moisture removable at that rotational speed level has been removed; increasing the rotational speed of the basket to a next, higher rotational speed level until all of the moisture removable at that rotational speed level has been removed; and repeating the prior step until a desired degree moisture removal has occurred. A control for use in an automatic washer which has a rotatable wash basket driven by an electric motor comprising: means for energizing said motor to rotate said basket at a first low speed level; means for periodically sensing an incremental amount of moisture removed from a fabric load within said wash basket; means for repeatedly increasing the rotational speed of said basket to a next higher speed level upon the occurrence of sensing an incremental amount of removed moisture below a preselected amount; and means for terminating the rotation of said basket when said increment amount of removed moisture is below a preselected amount at a predetermined maximum rotational speed level.
