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.
Claims18
A control method of a laundry machine, the laundry machine comprising a duct in communication with a tub and/or drum, a heater, a nozzle, and a blower which are each installed within the duct, a sensor which measures a temperature of an air in the duct, and a controller, the method comprising:
- judging, based on a temperature increase rate within the duct for a predetermined duration with the controller, an amount of water supplied to the heater for steam generation,
- wherein a first algorithm is performed by the controller to generate and supply steam to the tub and/or drum if the amount of supplied water exceeds a predetermined value, and
- wherein a second algorithm is performed by the controller so as not to generate steam if the amount of supplied water is less than the predetermined value, the second algorithm including performing a third drying to supply heated air to the laundry and supplying mist to the laundry.
