  • Patent number: 12000072
    Abstract: A method of operating a washing machine appliance includes filling a wash tub with a wash liquid during a first cycle. The method also includes receiving a pause input after filling the wash tub and before draining the wash tub during the first cycle. In response to the pause input, the first cycle is paused for a pause duration. The method further includes incrementing a pause counter in response to the pause input and storing the pause duration after pausing the first cycle. The method also includes filling the wash tub with a wash liquid during a second cycle after the first cycle and automatically pausing the second cycle after filling the wash tub with the wash liquid during the second cycle, based on the pause counter and the stored pause duration.

  • Patent number: 11043776
    Abstract: The present disclosure is directed to preventing serious injury or death by electrocution due to contact with a power source, such as an alternating current (AC) voltage source. Methods and apparatus consistent with the present disclosure may controllably provide an electrical voltage to an electrical conductor for a period of time and then remove that voltage from the electrical conductor before providing the electrical voltage to the electrical conductor a second time. By initially connecting the electrical voltage to the conductor, then removing that electrical voltage from the conductor before re-connecting that electrical voltage to the conductor, methods and apparatus consistent with the present disclosure allow a person to let go of the electrical conductor before the person is seriously injured or killed by an electrical shock in an instance where the body of the person is in physical contact with the electrical conductor.

    Abstract: A method of automatically initiating a procedure to adjust dosing of laundry treating chemistry after satisfying a threshold of determined over-sudsing conditions in a laundry treating appliance during a cycle of operation. When an over-sudsing condition is detected, an over-sudsing counter is initialized, and the data is stored in the memory of a laundry treating appliance as an aggregate total. Once a predetermined threshold is satisfied, a predetermined dosage of laundry treating chemistry is reduced and the over-sudsing counter is reset. The over-sudsing counter can also be reset in the event of an operational event such as a replenishment of a bulk treating chemistry, input by a user of a default value, or passing of a temporal reference, wherein the predetermined dosage is reset to a default value.

    Abstract: A method for washing articles in a wash chamber of the washing machine appliance is provided. The method includes providing a tub and a basket, the basket rotatably positioned within a tub, with an amount of wash water for washing one or more articles positioned in the basket. After the wash cycle, the method initiates a spin cycle while maintaining at least a minimum amount of wash water from the wash cycle in the basket and tub. Maintaining the wash water during the initiation of the spin cycle can assist in preventing an imbalance of the wash load. For example, the wash load may be more evenly distributed during the draining of the wash water, as the wash basket is spinning during such draining of the wash water.

    Abstract: A washing machine that performs refresh washing in which smell or mold that permeates laundry can be removed, and a method of controlling the washing machine. When clothes that are kept for a long time without being worn or laundries that are hardly contaminated due to a short wearing time are washed, a refresh washing course in which various smell or mold that permeates laundry can be removed using a very small amount of detergent, is performed. Thus, overuse of detergent caused by an excessive use of detergent can be prevented, and since the necessity for rinsing is low due to the use of the very small amount of detergent, an intermediate dehydration operation may be omitted, or an intermediate dehydration revolutions per minute (rpm) may be reduced so that washing and rinsing operations do not need to be excessively performed and thus damage of laundry is reduced.

  • Publication number: 20130081431
    Abstract: In a laundry washer, relatively short bursts of operation of a recirculation pump are coordinated with corresponding brief intervals of tub rotation during the initial fill periods. The aim is to thoroughly wet the clothes early in each wash/rinse phase to thus improve the wash/rinse effectiveness, while also avoiding excessive suds formation. Following the initial fill periods and during regular wash/rinse agitations, the recirculation system may also be employed to “recharge” the laundry load with detergent that has settled in the bottom of the tub. In a further aspect of the invention, some or all of the conventional intermediate spin extractions are omitted. In this manner, more water is carried over in the clothes from one wash/rinse cycle to the next. An intermediate spin of reduced speed (RPM) and duration as compared to typical normal intermediate spins may be employed between the wash phase and first rinse.

  • Patent number: 8302431
    Abstract: A commercial steam-cleaning laundry machine is configured to use steam instead of dry-cleaning chemicals or water as a primary cleaning agent for garments rotating in a drum of the commercial steam-cleaning laundry machine. In one embodiment of the invention, a steam injector at least partially exposed to an inner surface of the drum is configured to provide a MCU-controlled fresh steam injection into the drum during a cleaning cycle of the commercial steam-cleaning laundry machine. The fresh steam into the commercial steam-cleaning laundry machine is from an outtake of a standalone boiler system which is typically used for a variety of fabric treatment machines in a commercial laundry operation. A debris and clean steam/air separation chamber periodically or continuously separates and/or filters debris, chemicals, and/or other undesirable elements from the drum and evacuates clean or cleaned-up air and moistures to an air-out duct.

  • Publication number: 20120192450
    Abstract: In a washing machine, a power management apparatus and a method of controlling the same, washing operation and drying operation commands are input by a user, power rate information for each time period is received from an EMS, a drying operation execution time is confirmed, and power rates corresponding to the drying operation execution time are determined based on the power rate information for each time period. Then, the power rates corresponding to the drying operation execution time are compared with the standard power rates to determine whether the power rates corresponding to the drying operation execution time are higher than the standard power rates, and an algorithm of a final spinning mode in the washing operation is adjusted if the power rates corresponding to the drying operation execution time are higher than the standard power rates.
