摘要： A laundry appliance includes a drum that is rotationally operable about a rotational axis within a tub. The rotational axis is oriented in a generally horizontal configuration. An impeller is rotationally operable within the drum about the rotational axis. A dual-rotor motor is coupled to the drum and the impeller for providing separate and independent rotation of the drum and impeller about the rotational axis. An inner rotor of the dual-rotor motor is coupled with the impeller and an outer rotor of the dual-rotor motor is coupled with the drum.

摘要： A laundry machine includes a tub, a drum that is rotatably mounted in the tub, and an induction heater that is provided in the tub and configured to heat an outer circumferential surface of the drum. The laundry machine also includes a motor that is configured to rotate the drum, a user interface comprising a course selection unit that is configured to allow a user to select a course, and an option selection unit that is configured to allow the user to select option information that is related with the course selected. The laundry machine further includes a processor that is configured to control the drum rotation speed and the induction heater. The course selection unit comprises a wash-drying course that performs heat-spinning by default, the heat-spinning being configured to heat the drum by driving the induction heater when the drum rotates.

摘要： A method for controlling a laundry washing machine. The method includes: performing a tub loading process comprising operating supply valve(s) to provide a first volume of water through a detergent supply system and into a tub to fill the tub with wash liquid; performing a washing process comprising rotating a drum to agitate laundry in in the presence of the wash liquid; performing a static rinsing process comprising operating a pump to remove a free volume of wash liquid from the tub without rotating the drum; and performing one or more rinsing processes comprising: operating the supply valve(s) to provide a volume of clean rinse water to the tub, operating the pump to remove the rinse water from the drum, and operating the motor to spin the drum at high speed to extract rinse water from the laundry, while continuing to operate the pump.

摘要： Disclosed is a drum washing machine, including: a drum configured in an outer tank and capable of rotating by using an inclination axis as center; a stirring body configured at a rear part of the drum and including main blades in contact with washings; a driving unit enabling the drum and the stirring body to rotate at different rotating speeds; and a water supply mechanism part configured to splash water to a surface of the stirring body. The water supply mechanism part includes a first water storage part capable of moving between a position in water soaked in the outer tank and a position higher than the water and storing water when soaked in water of the outer tank, and a first outflow port capable of enabling water stored in the first water storage part to flow out to the surface of the stirring body at an upper position.
