(EN) DRAINING AND SPINNING CONTROL METHOD FOR SELF-CLEANING LAUNDRY MACHINE

Abstract
(EN) Provided is a draining and spinning control method for a self-cleaning laundry machine. The method comprises: arranging cleansing particles (4) in a space (3) between an inner drum (2) and an outer drum (1) of a laundry machine to cleanse an outer wall of the inner drum (2) and an inner wall of the outer drum (1) with the movement of a water flow, and receiving a draining instruction to open a draining valve (5); determining a quantity of the cleansing particles (4) per unit water volume in the space (3); and controlling a rotation speed of the inner drum (2) to adjust a frequency of friction and collision between the cleansing particles (4) and the walls of the inner and outer drums. The laundry machine arranges at least two control phases for draining and spinning processes according to the quantity of the cleansing particles (4) per unit water volume in the space (3). Different rotation manners are set for the inner drum in the respective control phases. In a control phase where the quantity of the cleansing particles (4) per unit water volume is larger, the rotation speed of the inner drum (2) is higher. During the draining and spinning processes, the laundry machine selects a corresponding control phase by detecting the quantity of the cleansing particles (4) per unit water volume in the space (3). The control method of the invention is simple, and can completely remove dirt from a drum wall of a laundry machine, thereby keeping a washing environment clean, preventing re-contamination, and improving clothes cleaning performance.
(FR) La présente invention concerne un procédé de commande de drainage et d'essorage pour une machine à laver autonettoyante. Le procédé comprend : l'agencement de particules de nettoyage (4) dans un espace (3) entre un tambour intérieur (2) et un tambour extérieur (1) d'une machine à laver pour nettoyer une paroi extérieure du tambour intérieur (2) et une paroi intérieure du tambour extérieur (1) avec le mouvement d'un écoulement d'eau, et la réception d'une instruction de drainage pour ouvrir une vanne de drainage (5) ; la détermination d'une quantité de particules de nettoyage (4) par volume d'eau unitaire dans l'espace (3) ; et la commande d'une vitesse de rotation du tambour intérieur (2) pour ajuster une fréquence de frottement et de collision entre les particules de nettoyage (4) et les parois des tambours intérieur et extérieur. La machine à laver agence au moins deux phases de commande pour des processus de drainage et d'essorage selon la quantité des particules de nettoyage (4) par volume d'eau unitaire dans l'espace (3). Différentes manières de rotation sont réglées pour le tambour intérieur dans les phases de commande respectives. Dans une phase de commande où la quantité des particules de nettoyage (4) par volume d'eau unitaire est plus grande, la vitesse de rotation du tambour intérieur (2) est plus élevée. Pendant les processus de drainage et d'essorage, la machine à laver sélectionne une phase de commande correspondante en détectant la quantité des particules de nettoyage (4) par volume d'eau unitaire dans l'espace (3). Le procédé de commande de l'invention est simple, et peut complètement éliminer la saleté d'une paroi de tambour d'une machine à laver, ainsi maintenant un environnement de lavage propre, empêchant la recontamination, et améliorant les performances de nettoyage de vêtements.
(ZH) 一种自清洁洗衣机排脱水控制方法,该洗衣机内外桶之间的空间(3)内设有随水流运动清洗内桶(2)外壁和外桶(1)内壁的清洗颗粒(4),接收排水指令,打开排水阀(5);判断空间(3)内水中单位体积清洗颗粒(4)的数量;控制内桶(2)的转速,调节清洗颗粒(4)与内外桶壁摩擦、碰撞的频率。洗衣机根据空间内水中单位体积清洗颗粒(4)的数量多少将排脱水过程分为至少两个控制阶段,每个阶段设有不同的内桶(2)转动方式,水中单位体积清洗颗粒(4)数量越多的阶段,内桶(2)转速越大。排脱水过程中,洗衣机根据检测空间(3)内水中单位体积清洗颗粒(4)的数量,选择对应的控制阶段。本发明控制方法简单,能够完全清除洗衣机桶壁污垢,保持洗涤环境清洁,杜绝二次污染,提高衣物洗净率。
