摘要： A washing machine appliance includes a wash tub defining a wash chamber, a wash basket rotatably mounted within the wash tub, and a motor operably coupled to the wash basket for selectively rotating the wash basket. A controller is configured for accelerating the wash basket to a predetermined speed during an acceleration period and maintaining that speed during a steady state period. The controller further determines a power drop from the maximum power required to accelerate the wash basket to the power required to maintain the predetermined speed, and the dry load weight is calculated using this power drop and a transfer function.

摘要： A method of controlling a washing machine that includes a drum rotatably provided in a tub that receives water, at least one nozzle spraying water into the drum, a washing motor rotating the drum, and a circulation pump circulating water within the washing machine, the method including: operating the washing motor to rotate the drum in a first rotational direction while repeatedly alternating between an acceleration and a deceleration of the drum so that laundry in the drum alternates between maintaining contact with an inner surface of the drum during acceleration, and separates from the inner surface of the drum during deceleration; and operating a circulation pump motor in the circulation pump, while the drum rotates in the first rotational direction, to accelerate a pump speed of the circulation pump during the acceleration of the drum, and to decelerate the pump speed during deceleration of the drum.

摘要： A laundry washing machine and method automate the selection of one or more parameters of a wash cycle of a laundry washing machine based in part on a color detection sensor disposed proximate an opening of the wash tub and configured to capture color composition data of one or more items added to the wash tub and a weight sensor operatively coupled to the wash tub, where the weight sensor is configured to detect the addition of an item among the one or more items to the wash tub and initiate capturing of the color composition data, and a controller is configured to configure one or more parameters for a wash cycle based upon the captured color composition data.

摘要： A method of operating a washing appliance includes obtaining images of a wash chamber using a camera assembly while the wash basket is tumbling a load of clothes positioned therein. The one or more images are analyzed using a machine learning image recognition process to determine a tumble condition of the load of clothes in the wash basket, e.g., whether the clothes are tumbling in the wash basket in a manner that generates suitable mechanical washing action. The motor assembly is then used to adjust a basket speed based at least in part on determining that the tumble condition deviates from a target tumble condition.

摘要： A portable handheld submersible ultrasonic cleaning device has a generally elongate body defining proximal and distal ends, a power supply and an ultrasonic transducer powered thereby, wherein the distal end exposes the ultrasonic transducer to agitate surrounding water when the base is submerged in the water use. A propeller device comprising a propeller may force the water across the ultrasonic transducer. When cleaning, the device may be held with the distal end thereof submerged for enhanced cleaning and removing surface contaminants such as dust, dirt, oil, pigments, bacteria and the like. The device may be stood upright upon the base on the floor of a container for hands-free application of ultrasound whilst cleaning.

摘要： Disclosed herein is a drum type washing machine capable of obtaining a high-water saving effect. The drum type washing machine comprises at least one processor configured to control a drive device configured to rotate a drum, a water supplier configured to supply water to a tub, and a sprinkler configured to spray water stored in the tub toward laundry accommodated in the drum. The drum comprises a lifter and a plurality of rear through-holes. The at least one processor is configured to perform a water spray process while rotating the drum in a state in which an amount of wash water absorbable by the laundry is maintained in the tub, in a washing cycle. In the water spray process, a waiting process, in which driving a circulation pump 91 is stopped, is intermittently and repeatedly performed.

摘要： Disclosed is a control method for a washing machine having three or more lifters inside a drum. The control method includes: positioning the lifters on an outer side of a first area including a drum lower portion, and positioning laundry on the first area; performing a first rotation step to rotate the drum in a first direction so that one of the lifters is positioned on the first area and the laundry is positioned on the lifter positioned on the first area; and performing a second rotation step to rotate the drum in a second direction opposite to the first direction, so that the lifters are positioned on the outer side of the first area and the laundry is positioned on the first area, wherein the first rotation step and the second rotation step are performed alternately and repeatedly.

摘要： A front-loading washing machine and a control method therefor are disclosed. The control method includes: when a sensed amount of laundry in a drum is equal to or less than a preset amount, rubbing step at which the drum is rotated in both directions, wherein the rubbing step comprises: a first rotation step at which the drum is rotated in a first direction by a preset one-direction rotational angle; and a second rotation step at which the drum is rotated by the one-direction rotational angle in a second direction opposite to the first direction, and wherein the first rotation step and the second rotation step are performed alternately and repeatedly. Accordingly, it is possible to perform a washing motion which improves washing performance and reduces wear and tear of the laundry.
