Abstract: Disclosed herein is a laundry machine. More particularly, a laundry machine for generating steam by an induction heater and a control method thereof are disclosed. According to an embodiment of the present disclosure, provided is a method of controlling a laundry machine including a tub, a drum rotatably arranged in the tub to accommodate an object and provided with a through hole on an outer circumferential surface thereof, and an induction heater provided to the tub, and configured to perform a steam operation. The steam operation may include heating a heating surface of the drum facing the induction heater by driving the induction heater, spraying, through a spray nozzle, water toward the heating surface heated in the heating operation, and rotating the drum such that the steam is introduced into the drum through the through hole in a space between the tub and the drum.

Abstract: Disclosed are a laundry treating apparatus, and more particularly, a laundry treating apparatus for heating a drum using an induction heater and a control method thereof.
The object treating apparatus includes a tub (2); a drum (3) rotatably disposed within the tub (2) and for accommodating an object therein; an induction heater (8) disposed on the tub (2) and configured to heat an outer circumferential face of the drum (3) contacting the heater; a motor (6) to rotate the drum (3); and an upper temperature sensor (96) configured to detect a temperature around a space between the tub (2) and the drum (3), wherein the upper temperature sensor is disposed at an upper portion of the tub (2) and inside the tub (2); a lower temperature sensor (95) configured to detect a temperature around condensed water stored on a bottom of the tub (2), wherein the lower temperature sensor (95) is disposed at a lower portion of the tub (2) and inside the tub (2), wherein humid steam evaporated in heat exchange between the heated drum (3) and the object is condensed into the condensed water inside the tub (2) and the condensed water flows to the bottom of the tub (2); and a processor (9) configured to control a rotation of the drum (3) and an operation of the induction heater (8) to heat the drum (3) to heat and dry the object, wherein the processor (9) is further configured to determine an ending timing of the drying of the object based on a difference (delta T) between a temperature detected by the upper temperature sensor (96) and a temperature detected by the lower temperature sensor (95).

Abstract: The present invention relates to a laundry care apparatus in which an induction module heats the drum uniformly using a magnetic field to dry laundry or heat wash-water, and center and front and rear regions of the drum are uniformly heated. The induction module comprises a coil formed by turns of a wire and includes a rectangular shaped base housing for accommodating the coil, said base housing comprising straight sections and corner sections; In order to prevent the coil from being detached from the induction module due to vibration, the structure of the base housing is formed with ribs protruding upwards to define a slot for accommodating the coil, wherein the ribs are thermo-fused; A thermal-fusing line is defined in each of the corner sections of the base housing.
