Abstract: front page image
(EN)The present invention relates to a drain pump driving apparatus and a laundry processing apparatus comprising the same. The drain pump driving apparatus and the laundry processing apparatus comprising the same, according to an embodiment of the present invention, comprise: a motor for operating a drain pump; an inverter for converting direct current power to alternating current power by a switching operation and outputting the converted alternating current power to the motor; an output current detection unit for detecting an output current flowing to the motor; and a control unit for controlling the inverter, wherein the control unit can calculate an RPM ripple of the motor on the basis of an output current, and can change the RPM of the motor on the basis of the calculated RPM ripple of the motor. As such, it is possible to reduce noise during drainage.
(FR)La présente invention concerne un appareil d’entraînement de pompe de vidange et un appareil de traitement du linge le comprenant. L'appareil d'entraînement de pompe de vidange et l'appareil de traitement du linge le comprenant, selon un mode de réalisation de la présente invention, comprennent : un moteur permettant d'actionner une pompe de vidange ; un onduleur permettant de convertir la puissance en courant continu en puissance en courant alternatif par une opération de commutation et de délivrer en sortie la puissance en courant alternatif convertie au moteur ; une unité de détection de courant de sortie permettant de détecter un courant de sortie circulant vers le moteur ; et une unité de commande permettant de commander l'onduleur, l'unité de commande pouvant calculer une fluctuation des tr/min du moteur en fonction d'un courant de sortie, et pouvant changer les tr/min du moteur d'après la fluctuation des tr/min calculée du moteur. Il est ainsi possible de réduire le bruit pendant la vidange.
(KO)본 발명은 배수펌프 구동장치, 및 이를 구비한 세탁물 처리기기에 관한 것이다. 본 발명의 실시예에 따른 배수펌프 구동장치 및 이를 구비하는 세탁물 처리기기는, 배수 펌프를 동작하기 위한 모터와, 스위칭 동작에 의해, 직류 전원을 교류 전원으로 변환하고, 변환된 교류 전원을 모터에 출력하는 인버터와, 모터에 흐르는 출력 전류를 검출하는 출력 전류 검출부와, 인버터를 제어하는 제어부를 구비하고, 제어부는, 출력 전류에 기초하여, 모터의 속도 리플을 연산하고, 연산된 모터 속도 리플에 기초하여, 모터의 속도를 가변할 수 있다. 이에 따라, 배수시의 노이즈를 저감할 수 있게 된다.
