The present invention relates to an artificial intelligence washing machine and an operation method thereof. A method of operating a washing machine may comprise estimating, based on a previous setting of a previous washing operation, an estimated setting for a current washing operation, wherein the estimated setting includes a water supply time, a drainage time, and a spin-drying time, obtaining a user input, obtaining an amount of laundry from a weight sensor of the washing machine, determining, based on the estimated setting, the user input, and the amount of laundry, a washing time for the current washing operation and displaying the determined washing time to the user. Accordingly, the estimated washing time is provided with the reflection of data of the washing machine which has been accumulated by the increase of the number of uses, thereby reducing a difference between an actual operating time and the estimated washing time and minimizing the user inconvenience.

A washing machine that can shorten the drying time by improving the drying efficiency of the washing machine. A washing machine includes a tub, a drum rotatably installed inside of the tub, a condensing duct formed on an inner wall of the tub, a heating duct provided outside the tub, a duct heater provided inside the heating duct, a fan configured to circulate air in the drum, the condensing duct, and the heating duct and a controller configured to rotate the drum at a first rotational speed so as to tumble laundry contained in the drum while controlling the duct heater to heat the air circulated by the fan. The controller may rotate the drum at a second rotational speed, which is higher than the first rotational speed to separate water from the laundry contained in the drum while controlling the duct heater to heat the circulating air.

A laundry treating appliance and method of operating a laundry treating appliance that includes wetting the laundry load in a drum according to a selected cycle of operation and determining a magnitude of imbalance of the wetted laundry load. A controller of the laundry treating appliance is configured to determine a first extraction speed for rotating the drum based on the magnitude of imbalance.

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.
