Abstract
(EN)
A dewatering machine, capable of monitoring abnormal vibrations in stable rotation of a rotary tub for dewatering washing objects. The dewatering machine (1) comprises: a motor (6) for enabling the rotation of a rotary tub (4) of a dewatering tub (16), an acceleration sensor (27) for detecting vibration of the dewatering tub (16), and a control unit (21). The control unit (21) is configured to control the motor (6), so that the rotational speed of the motor (6) increases to a specified dewatering rotational speed and then the motor stably rotates at the dewatering rotational speed, so as to dewater the washing objects (Q) in the rotary tub (4). The control unit (21) acquires a peak-to-peak value of a detection value of the acceleration sensor (27) during each of a plurality of sampling periods in the stable rotation of the motor (6) at the dewatering rotational speed. If the peak-to-peak value is equal to or greater than a specified threshold, the control unit (21) adds one to the count value. When the count value reaches a specified value, the control unit (21) determines that there is an imbalance of a specified or larger size in the rotary tub (4).

La présente invention concerne une machine de déshydratation, permettant de surveiller des vibrations anormales dans une rotation stable d'une cuve rotative pour déshydrater des objets de lavage. La machine de déshydratation (1) comprend : un moteur (6) pour permettre la rotation d'une cuve rotative (4) d'une cuve de déshydratation (16), un capteur d'accélération (27) pour détecter une vibration de la cuve de déshydratation (16), et une unité de commande (21). L'unité de commande (21) est conçue pour commander le moteur (6), de telle sorte que la vitesse de rotation du moteur (6) augmente jusqu'à une vitesse de rotation de déshydratation spécifiée, puis le moteur tourne de façon stable à la vitesse de rotation de déshydratation, de façon à assécher les objets de lavage (Q) dans la cuve rotative (4). L'unité de commande (21) acquiert une valeur de pic à pic d'une valeur de détection du capteur d'accélération (27) pendant chaque période d'une pluralité de périodes d'échantillonnage pendant la rotation stable du moteur (6) à la vitesse de rotation de déshydratation. Si la valeur de pic à pic est supérieure ou égale à un seuil spécifié, l'unité de commande (21) ajoute un à la valeur de comptage. Lorsque la valeur de comptage atteint une valeur spécifiée, l'unité de commande (21) détermine qu'il existe un déséquilibre d'une importance spécifiée ou plus grande dans la cuve rotative (4).

一种脱水机,其能监视用于将洗涤物脱水的旋转桶的稳定旋转中的异常振动。脱水机(1)包括:使脱水桶(16)的旋转桶(4)旋转的马达(6)、检测脱水桶(16)的振动的加速度传感器(27)以及控制部(21)。控制部(21)为控制马达(6),使得马达(6)的转速上升到规定的脱水转速之后以脱水转速稳定旋转,以使旋转桶(4)内的洗涤物(Q)脱水。控制部(21)在脱水转速下的马达(6)的稳定旋转中的多个采样期间的各个期间获取加速度传感器(27)的检测值的峰间值。如果峰间值为规定的阈值以上,则控制部(21)将计数值加1。当计数值达到规定值时,控制部(21)判断旋转桶(4)中存在规定以上大小的不平衡。
