  • Patent number: 9644306
    Abstract: A method of controlling steam supply in a laundry machine. The control method includes heating a predetermined space within a duct in communication with a tub and/or drum of the laundry machine to a higher temperature than a temperature of the other space within the duct, directly supplying water to the heated predetermined space to generate steam, and supplying air flow toward the heated predetermined space so as to supply the generated steam into the laundry.

  • Patent number: 9334601
    Abstract: A method of controlling steam supply in a laundry machine. The control method includes heating a predetermined space within a duct in communication with a tub and/or drum of the laundry machine to a higher temperature than a temperature of the other space within the duct, directly supplying water to the heated predetermined space to generate steam, supplying air flow towards the heated predetermined space so as to supply the generated steam into the tub, and judging the amount of water supplied during the supply of water based on a temperature increase rate within the duct for a predetermined time.
