  • Patent number: 10563338
    Abstract: Laundry appliances use machine learning models and/or personalization to provide better treatments. As one example, a laundry appliance has a chamber in which laundry items are placed for treatment. Sensor(s) are positioned to sense contents of the chamber or to sense the laundry items as they are loaded into the chamber. The machine learning model uses data from these sensors to determine various attributes of the laundry items and/or the treatment, such as the type of fabric and/or how dirty the items are, and the treatment process is controlled accordingly. Personalized data, such as an individual's preferences for laundry treatments or his sensitivities and allergies, may also be used to personalize the treatment process.

    Abstract: A drive-signal-generating circuit includes: a current-detecting unit to detect a current flowing through a three-phase motor; a calculating unit to calculate d- and q-axis currents based on a detection output of the current detecting unit; a reference-signal-output unit to output a reference signal indicating a first-reference value of the q-axis current for rotating the motor at a target-rotational speed; first- and second-control-signal-output units to output first- and second-control signals corresponding to respective errors between current values of the d- and q-axis currents and a second and the first reference values, respectively; a drive-signal-output unit to output such a drive signal that the d- and q-axis currents reach the second and first reference values, respectively; and an adjusting unit to adjust the detection output so that a ripple of the second-control signal become smaller, after a rotational speed of the motor reaches a predetermined rotational speed corresponding to the target-rotatio

  • Patent number: 9121121
    Abstract: A method for driving laundry to roll in an upright tub with a pulsator and uses of the same are disclosed. The method makes laundry alternately but not simultaneously form at least two rolling faces in the upright tub. The rolling faces have a certain angle therebetween, laundry is performed more than one rolling on one of the rolling faces and then switched to another rolling face to be performed more than one rolling on the other rolling face. There is at least one pulsator to provide a side auxiliary force during rolling processes. The number of the pulsators driving laundry is preferably 3˜5, the number of rib on the pulsator is preferably 3˜8. The method can significantly improve cleaning performance and provide the advantage of multi-direction rolling.

  • Patent number: 9103060
    Abstract: The present invention relates to a washing machine and a method of operating the washing machine. In operating the washing machine according to inputted settings, each washing cycle is divided into a plurality of steps, and a washing tub or pulsator is controlled to be differently operated for each step. Accordingly, the washing machine may be operated in various patterns to effectively remove contaminants from the laundry.

  • Patent number: 9080276
    Abstract: A method of operating a washing machine to detect unbalanced loads has been developed. The method includes operating a motor to rotate a tub holding a load at a first rotational rate that is below a threshold rotational rate, identifying a mass of the load, operating the motor to rotate the tub at a second rotational rate that is above the threshold rotational rate, identifying a power applied to the motor to continue rotation of the tub at the second rotational rate, obtaining an out of balance mass value from a memory with reference to the power applied to the motor, second rotational rate, and identified mass, identifying a maximum rate for the tub with reference to the out of balance mass value, and operating the motor to rotate the tub at a rate that is less than or equal to the maximum rate.
