| 20100000267 | Spin Drain Cycles for Reduction of Load Tangling in Abbreviated or No Central Column Top Load Laundry Washer - In place of a static drain, a final tub spin interval during a wash cycle and/or rinse cycle of a laundry washing machine/process is continued at the time that the main drain of the free liquid in the wash tub is initiated. This spin may continue until completion of the drain and extraction. In one embodiment, the sequence includes a transition from a relatively slow speed spin of a rinse or wash agitation interval to a high speed extraction spin. Thus, the conventional transition from the rinse and/or wash cycle to a static drain is eliminated. In addition, the conventional transition from a static drain to a high-speed extraction spin drain is eliminated. Such a change in the operation sequence of the washer can help reduce tangling and/or balling of the wash load, especially in a washer having an abbreviated or no central column/agitator. Such a change can also reduce associated imbalance during the spin drain, which can benefit machines both with and without a central agitator. | 01-07-2010 |
