Mechanical force is applied to the laundry while repeating this flow. Of course, these RPMs may vary depending on the washing course.

  • the motor RPM When the flow level of the fabric is "weak", the motor RPM is increased and additional water supply can be performed. In this case, an increase in motor RPM and additional water supply may be performed in parallel. However, the main cause of the low flow level of the fabric in the current state may be one of motor RPM and water level. Therefore, after the RPM increase control is performed first, the additional water supply can be performed only after the bubble flow level is weak. This is because, when more than necessary washing water is injected through additional water supply, waste of washing water is caused. After additional water supply of the washing water, the motor RPM can be controlled differently by re-evaluating the flow level of the fabric.

Abstract

La présente invention concerne un dispositif de traitement de linge et, plus particulièrement, un dispositif de traitement de linge comportant un appareil de prise de vues, ainsi qu'un procédé de commande associé. Selon un mode de réalisation de la présente invention, l'invention concerne un procédé de commande pour un lave-linge, comprenant, afin d'effectuer un lavage ou un rinçage, une étape de mouvement de linge consistant à entraîner un tambour ou un pulsateur qui forme un courant d'eau de sorte que l'eau de lavage et le linge bougent dans le tambour, une étape de production, dans l'étape de mouvement de linge, d'une image en série chronologique pour le mouvement du linge en photographiant l'intérieur du tambour par le biais d'un appareil de prise de vues, une étape d'identification de l'état de mouvement actuel du linge par le biais de l'image en série chronologique, une étape consistant à fournir de l'eau supplémentaire par entraînement d'une soupape d'alimentation en eau en fonction de l'état de circulation du linge, et une étape consistant à effectuer un lavage ou un rinçage par entraînement du tambour ou du pulsateur après l'alimentation en eau supplémentaire.
