Title
(EN) LAUNDRY MACHINE HAVING INDUCTION HEATER AND CONTROL METHOD THEREOF
(FR) LAVE-LINGE COMPRENANT UN DISPOSITIF DE CHAUFFAGE PAR INDUCTION ET PROCÉDÉ DE COMMANDE ASSOCIÉ
Abstract
(EN)
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.

L'invention concerne un lave-linge. Plus particulièrement, l'invention concerne un lave-linge capable de produire de la vapeur par un dispositif de chauffage par induction et un procédé de commande associé. Selon un mode de réalisation de la présente invention, l'invention concerne un procédé de commande d'un lave-linge comprenant une cuve, un tambour agencé avec faculté de rotation dans la cuve pour recevoir un objet et pourvu d'un trou traversant sur sa surface périphérique externe, et un dispositif de chauffage par induction disposé sur la cuve, et conçu pour effectuer une opération de production de vapeur. L'opération de production de vapeur peut comprendre le chauffage d'une surface de chauffage du tambour faisant face au dispositif de chauffage par induction par la commande du dispositif de chauffage par induction, la pulvérisation, par l'intermédiaire d'une buse de pulvérisation, d'eau vers la surface de chauffage chauffée dans l'opération de chauffage, et la rotation du tambour de telle sorte que la vapeur est introduite dans le tambour par le trou traversant dans un espace situé entre la cuve et le tambour.
