发明内容 Summary of the invention

在专利文献1～3的洗衣机中，由于用于消除滚筒内的洗涤物的偏倚的松散处理说不上充分，因而难以有效地消除洗涤物的偏倚。In the washing machines of Patent Documents 1 to 3, since the loosening treatment for eliminating the deviation of the laundry in the drum is not sufficient, it is difficult to effectively eliminate the bias of the laundry.

本发明是基于该背景而完成的，其目的在于，提供能够有效地消除滚筒内的洗涤物的偏倚的洗衣机。The present invention has been made in view of the background, and an object thereof is to provide a washing machine capable of effectively eliminating the bias of laundry in a drum.

此外，本发明的特征在于，所述控制单元在所述判断单元判断存在洗涤物的偏倚的情况下，在使所述滚筒和所述旋翼以互不相同的速度进行旋转之后，使所述制动单元工作从而对所述滚筒的旋转施加制动。Further, the present invention is characterized in that, in the case where the judging unit judges that there is a bias of the laundry, the control unit causes the drum and the rotor to rotate at mutually different speeds to make the system The moving unit operates to apply a brake to the rotation of the drum.

此外，本发明的特征在于，所述控制单元在所述判断单元判断存在洗涤物的偏倚的情况下，控制所述驱动单元使得所述滚筒和所述旋翼进行等速旋转，在这之后所述判断单元仍然判断存在洗涤物的偏倚的情况下，控制所述驱动单元使得所述滚筒和所述旋翼以互不相同的速度进行旋转。Further, the present invention is characterized in that the control unit controls the drive unit to cause the drum and the rotor to rotate at a constant speed in a case where the determination unit determines that there is a bias of the laundry, after which the In the case where the judging unit still judges that there is a bias of the laundry, the driving unit is controlled such that the drum and the rotor rotate at mutually different speeds.

此外，本发明的特征在于，包括向所述滚筒内供水的供水单元，所述控制单元在所述判断单元反复判断存在洗涤物的偏倚的次数达到规定次数的情况下，通过所述供水单元向所述滚筒内供水，控制所述驱动单元使得所述滚筒进行旋转。Further, the present invention is characterized in that it includes a water supply unit that supplies water into the drum, and the control unit, when the determination unit repeatedly determines that the number of times the laundry is biased reaches a predetermined number of times, passes through the water supply unit Water is supplied to the drum, and the driving unit is controlled such that the drum rotates.

根据本发明，在具有水平或倾斜配置的滚筒的洗衣机中，在洗涤物的脱水开始之前，判断滚筒内的洗涤物有无偏倚。According to the present invention, in a washing machine having a drum in a horizontal or inclined configuration, dehydration of the laundry Before starting, judge whether the laundry in the drum is biased.

在判断没有发生洗涤物的偏倚的情况下，不会徒劳地进行用于消除洗涤物的偏倚的处理，而会迅速地开始洗涤物的脱水。In the case where it is judged that the deviation of the laundry does not occur, the treatment for eliminating the bias of the laundry is not in vain, and the dehydration of the laundry is quickly started.

在判断存在洗涤物的偏倚的情况下，滚筒和滚筒内的旋翼以互不相同的速度进行旋转。由此，由于在滚筒内偏倚的洗涤物分别受到来自滚筒以及旋翼的冲击而变得容易松散，因此能够有效地消除滚筒内的洗涤物的偏倚。In the case where it is judged that there is a bias of the laundry, the rotors in the drum and the drum rotate at different speeds from each other. Thereby, since the laundry which is biased in the drum is easily loosened by the impact from the drum and the rotor, the deviation of the laundry in the drum can be effectively eliminated.

此外，在判断存在洗涤物的偏倚的情况下，在为了消除偏倚而使滚筒和旋翼以互不相同的速度进行旋转之前，通过对滚筒的旋转施加制动，由于在滚筒内偏倚的洗涤物受到制动器的冲击而变得更加容易松散，因此能够更加有效地消除滚筒内的洗涤物的偏倚。Further, in the case where it is judged that there is a bias of the laundry, before the drum and the rotor are rotated at mutually different speeds in order to eliminate the bias, by applying a brake to the rotation of the drum, the laundry which is biased in the drum is subjected to the laundry. The impact of the brake becomes easier to loosen, so that the bias of the laundry in the drum can be more effectively eliminated.

此外，根据本发明，由于在判断存在洗涤物的偏倚的情况下，在为了消除偏倚使滚筒和旋翼以互不相同的速度进行旋转之后，通过对滚筒的旋转施加制动，从而在滚筒内偏倚的洗涤物受到制动器的冲击而更加变得容易松散，因此能够更加有效地消除滚筒内的洗涤物的偏倚。Further, according to the present invention, since it is judged that there is a bias of the laundry, after the drum and the rotor are rotated at mutually different speeds in order to eliminate the bias, the brake is applied to the rotation of the drum, thereby biasing in the drum The laundry is more easily loosened by the impact of the brake, so that the deviation of the laundry in the drum can be more effectively eliminated.

此外，根据本发明，在判断存在洗涤物的偏倚的情况下，若洗涤物的偏倚较小，则只通过使滚筒和旋翼进行等速旋转，就能够迅速地消除洗涤物的偏倚。在洗涤物的偏倚大到即使这样也不能消除的情况下，通过使滚筒和旋翼以相互不同的速度进行旋转，从而即使是大的偏倚也能够消除。Further, according to the present invention, in the case where it is judged that there is a bias of the laundry, if the deviation of the laundry is small, the deflection of the laundry can be quickly eliminated only by rotating the drum and the rotor at a constant speed. In the case where the deviation of the laundry is so large that even if it cannot be eliminated, the drum and the rotor are rotated at different speeds, so that even a large bias can be eliminated.

此外，根据本发明，在洗涤物的偏倚大到存在洗涤物的偏倚的判断反复出现了规定次数的情况下，通过在滚筒内将洗涤物浸入到供给的水中并且使滚筒旋转，从而能够有效地松散洗涤物，可靠地消除洗涤物的偏倚。Further, according to the present invention, in the case where the determination of the deviation of the laundry is so large that the deviation of the laundry is repeated a predetermined number of times, it is possible to effectively immerse the laundry in the supplied water and rotate the drum in the drum, thereby effectively Loose laundry, reliably eliminating the bias of the laundry.

In the case where a plurality of convex portions 19 are provided, the concave portions 24 and the convex portions 11 are provided in equal numbers.

齿轮切换装置7包括由螺线管等构成的促动器25、以及从促动器25伸出的工作片26。工作片26的顶端部26A与外轮齿轮21的外周面卡合。当促动器25工作时，如粗线箭头所示工作片26随着外轮齿轮21沿着倾斜方向K进行往返直线移动。由此，外轮齿轮21保持与各行星齿轮15咬合的状态，并且沿着倾斜方向K进行移动。The gear switching device 7 includes an actuator 25 composed of a solenoid or the like, and a work piece 26 extending from the actuator 25. The distal end portion 26A of the working piece 26 is engaged with the outer peripheral surface of the outer ring gear 21. When the actuator 25 is in operation, the work piece 26 is linearly moved back and forth along the tilting direction K as the outer wheel gear 21 as indicated by the thick arrow. Thereby, the outer ring gear 21 is kept in a state of being engaged with the respective planetary gears 15, and is moved in the oblique direction K.

将已向后方Y2最大限度地移动时的外轮齿轮21的位置称为“1轴侧”，将已向前方Y1最大限度地移动时的外轮齿轮21的位置称为“2轴侧”。图1的外轮齿轮21位于1轴侧和2轴侧之间的中立位置。齿轮切换装置7为使外轮齿轮21在1轴侧和2轴侧之间移动的装置。The position of the outer ring gear 21 when the rearward Y2 is maximally moved is referred to as "one axis side", and the position of the outer ring gear 21 when the front side Y1 is moved to the maximum is referred to as "two axis side". The outer ring gear 21 of Fig. 1 is located at a neutral position between the one-axis side and the two-axis side. The gear switching device 7 is a device that moves the outer ring gear 21 between the one-axis side and the two-axis side.

当外轮齿轮21位于1轴侧时，搅拌器5的旋转轴16的凸缘部18的凸部19从后方Y2嵌入外轮齿轮21的凹部24，外轮齿轮21与旋转轴16连结，且能够与其一体旋转。在该状态下当电机6工作且转子20进行旋转时，在传递机构22中，太阳齿轮17、各行星齿轮15以及外轮齿轮21以轴线13为中心向相同方向进行等速旋转。由此，行星齿轮15侧的滚筒4和太阳齿轮17侧的搅拌器5以轴线13为中心向圆周方向S上的相同方向进行等速旋转。此时，各行星齿轮15不以支承轴14为中心进行自转。When the outer ring gear 21 is located on the one-axis side, the convex portion 19 of the flange portion 18 of the rotating shaft 16 of the agitator 5 is fitted into the concave portion 24 of the outer ring gear 21 from the rear Y2, and the outer ring gear 21 is coupled to the rotating shaft 16, and can be integrated therewith. Rotate. When the motor 6 is operated and the rotor 20 is rotated in this state, in the transmission mechanism 22, the sun gear 17, the planetary gears 15, and the outer gear 21 rotate in the same direction at the same direction about the axis 13. Thereby, the drum 4 on the planetary gear 15 side and the agitator 5 on the sun gear 17 side rotate at a constant speed in the same direction in the circumferential direction S around the axis 13 . At this time, each of the planetary gears 15 does not rotate around the support shaft 14.

当外轮齿轮21位于2轴侧时，外槽3的底壁3B的凸部11从前方Y1嵌入外轮齿轮21的凹部23，外轮齿轮21与外槽3连结，无法旋转。在该状态下当电机6工作并且转子20进行旋转时，在传递机构22中，太阳齿轮17以轴线13为中心进行旋转，各行星齿轮15以支承轴14为中心进行自转，并且朝向与太阳齿轮17的旋转方向相同的方向在太阳齿轮17周围进行公转。由此，太阳齿轮17侧的搅拌器5以轴线13为中心进行旋转，行星齿轮15侧的滚筒4以通过搅拌器5减速后的速度，以轴线13为中心向与搅拌器5相同的方向进行旋转。传递机构22的减速比设定为例如1：2.75。When the outer ring gear 21 is positioned on the two-axis side, the convex portion 11 of the bottom wall 3B of the outer tub 3 is fitted into the concave portion 23 of the outer ring gear 21 from the front Y1, and the outer ring gear 21 is coupled to the outer groove 3 so as not to rotate. In this state, when the motor 6 is operated and the rotor 20 is rotated, in the transmission mechanism 22, the sun gear 17 rotates about the axis 13 and the planetary gears 15 rotate around the support shaft 14 and are oriented toward the sun gear. The direction in which the rotation direction of 17 is the same is revolved around the sun gear 17. Thereby, the agitator 5 on the side of the sun gear 17 rotates around the axis 13 , and the drum 4 on the side of the planetary gear 15 rotates in the same direction as the agitator 5 around the axis 13 at a speed decelerated by the agitator 5 . Rotate. The reduction ratio of the transmission mechanism 22 is set to, for example, 1:2.75.

如上，电机6通过与传递机构22以及齿轮切换装置7联动，使滚筒4以及搅拌器5分别以等速或不同的速度进行旋转。滚筒4内的洗涤物L通过旋转的滚筒4以及搅拌器5的搅拌叶片5A被一边搅拌一边洗涤。As described above, the motor 6 is rotated in conjunction with the transmission mechanism 22 and the gear switching device 7, so that the drum 4 and the agitator 5 are rotated at a constant speed or at different speeds. The laundry L in the drum 4 is rotated The drum 4 and the stirring blade 5A of the agitator 5 are washed while being stirred.

The rotational speed read by the rotational speed reading device 39 is input to the control unit 30 in real time. The control unit 30 controls the motor 6 based on the input rotational speed to adjust the rotational speed of the motor 6 to a desired value.

接下来，关于在洗衣机1中进行的洗涤运转的一部分进行说明。具体地说，作为洗涤运转的一个例子，设为连续进行清洗过程、一次或多次漂洗过程、以及脱水过程，在图3中，关于经过漂洗过程的最后阶段和脱水过程的初始阶段的洗涤运转的流程进行说明。此外，在说明图3时，也一并参照图4的时间图。在图4的时间图中，横轴表示经过的时间，纵轴表示电机6的转速。Next, a part of the washing operation performed in the washing machine 1 will be described. Specifically, as an example of the washing operation, it is assumed that the washing process, the one or more rinsing processes, and the dehydrating process are continuously performed, and in FIG. 3, regarding the final stage of the rinsing process and the initial stage of the dehydration process. The flow of the washing operation is explained. In addition, in explaining FIG. 3, the time chart of FIG. 4 is also referred to together. In the time chart of Fig. 4, the horizontal axis represents the elapsed time, and the vertical axis represents the rotational speed of the motor 6.

控制部30在用蓄在滚筒4中的水漂洗洗涤物L的漂洗过程的最后阶段，首先，打开排水阀43排出滚筒4内的水(步骤S1)，在此之后，将传递机构22的外轮齿轮21切换到1轴侧(步骤S2)。The control unit 30 first opens the drain valve 43 to discharge the water in the drum 4 at the final stage of the rinsing process of rinsing the laundry L with the water stored in the drum 4 (step S1), after which the outer wheel of the transmission mechanism 22 is used. The gear 21 is switched to the one-axis side (step S2).

当滚筒4内的水的水位下降到可以开始脱水的水位即开始脱水水位时(在步骤S3中为“是”)，控制部30将存储于存储器32的判断次数清除为0(零)(步骤S4)。When the water level of the water in the drum 4 drops to the water level at which dehydration can be started, that is, when the dehydration level is started (YES in step S3), the control unit 30 clears the number of judgments stored in the memory 32 to 0 (zero) (step) S4).

接着，在时间图的定时T₁处，控制部30使至今一直停止着的电机6的转子20从前方Y1观察进行右旋转，渐渐提高其旋转速度(步骤S5)。此时，由于外轮齿轮21位于1轴侧，因而滚筒4以及搅拌器5都处于与转子20直接连结的状态，向相同方向进行等速旋转，并且渐渐提高各自的旋转速度。通过渐渐提高旋转速度，能够在滚筒4的内周面上使滚筒4内的洗涤物L尽可能均匀地向圆周方向S分散。Next, at the timing T ₁ of the time chart, the control unit 30 causes the rotor 20 of the motor 6 that has been stopped so far to rotate rightward from the front Y1, and gradually increases the rotation speed (step S5). At this time, since the outer ring gear 21 is located on the one-axis side, the drum 4 and the agitator 5 are both directly coupled to the rotor 20, and are rotated at the same speed in the same direction, and the respective rotational speeds are gradually increased. By gradually increasing the rotation speed, the laundry L in the drum 4 can be dispersed in the circumferential direction S as uniformly as possible on the inner circumferential surface of the drum 4.

当在时间图的定时T₂处转子20的转速上升到100rpm时，控制部30将转子20的转速维持在100rpm，使转子20从前方Y1观察向右旋转一圈(步骤S6)。控制部30通过转速读取装置39读取该旋转一圈期间的转子20的转速的偏差(步骤S7)。该旋转一圈相当于时间图的定时T₂～T₃期间。此外，以下称“左”和“右”的情况为从前方Y1观察时的左和右的意思。When the rotation speed of the rotor 20 rises to 100 rpm at the timing T ₂ of the time chart, the control unit 30 maintains the rotation speed of the rotor 20 at 100 rpm, and rotates the rotor 20 one turn to the right as viewed from the front Y1 (step S6). The control unit 30 reads the deviation of the number of revolutions of the rotor 20 during one rotation of the rotation by the rotation speed reading device 39 (step S7). This one rotation corresponds to the timing T ₂ to T ₃ of the time chart. Further, the case of "left" and "right" hereinafter is the meaning of left and right when viewed from the front Y1.

所谓的100rpm的转速为洗涤物L通过滚筒4旋转时的离心力被压到滚筒4的内周面上的转速。控制部30控制电机6使转子20的转速维持为100rpm，然而实际上，由于滚筒4内的洗涤物L的偏倚，转子20的转速不会精确地维持为100rpm，会有偏差。The so-called rotation speed of 100 rpm is the number of revolutions of the laundry L that is pressed against the inner circumferential surface of the drum 4 by the centrifugal force when the drum L is rotated by the drum 4. The control unit 30 controls the motor 6 to maintain the rotation speed of the rotor 20 at 100 rpm. However, in actuality, the rotation speed of the rotor 20 is not accurately maintained at 100 rpm due to the bias of the laundry L in the drum 4, which may vary.

具体地，在洗涤物L在滚筒4中由于偏倚并集中而重叠了的部分位于最下面的情况下，当想要将该部分通过滚筒4的旋转扬起时，电机6需要很大的转矩。但是，由于通过控制部30所进行的电机6的控制不能立刻做出反应，因而转速瞬间变低。反过来，在想要将洗涤物L没有偏倚的部分在滚筒4中通过滚筒4的旋转扬起的情况下，由于通过控制部30所进行的电机6的控制的反应迅速，因而转速变高。因此，转子20的转速会产生偏差。Specifically, in the case where the portion in which the laundry L is overlapped in the drum 4 due to the bias and concentration is located at the lowermost position, the motor 6 requires a large torque when it is desired to lift the portion through the rotation of the drum 4. . However, since the control of the motor 6 by the control unit 30 cannot immediately react, the rotational speed instantaneously becomes low. Conversely, in the case where the portion where the laundry L is not biased is raised in the drum 4 by the rotation of the drum 4, the reaction of the motor 6 by the control portion 30 is quickly reacted. Speed, and thus the speed becomes higher. Therefore, the rotational speed of the rotor 20 is deviated.

偏差越大，越多的洗涤物L处于局部堆积地置于滚筒4的圆周方向S上的一部分处的状态，这意味着洗涤物L的偏倚较大。因此，在步骤S7中读取转子20的转速的偏差的转速读取装置39，为用于检测滚筒4内的洗涤物L的偏倚的结构。The larger the deviation, the more the laundry L is in a state of being partially deposited on a portion of the drum 4 in the circumferential direction S, which means that the laundry L has a large bias. Therefore, the rotational speed reading device 39 that reads the deviation of the rotational speed of the rotor 20 in step S7 is a structure for detecting the bias of the laundry L in the drum 4.

当在偏倚较大的状态下作为脱水运转使滚筒4以高速进行脱水旋转时，滚筒4会大幅度晃动而施加给洗衣机1较大的振动，产生噪声并且由于用于使滚筒4旋转的能量被振动获取，因而会产生滚筒4无法达到目标转速的问题。When the drum 4 is dehydrated and rotated at a high speed as a dehydrating operation in a state where the bias is large, the drum 4 is greatly shaken to apply a large vibration to the washing machine 1, generating noise and due to the energy for rotating the drum 4 is The vibration is acquired, and thus the problem that the drum 4 cannot reach the target rotational speed is generated.

控制部30基于步骤S7中的通过转速读取装置39所得的检测结果，根据旋转一圈期间的转子20的转速的偏差是否大到规定以上，具体地说根据转速的最大值Tmax和最小值Tmin的差是否在3rpm以上，判断在滚筒4内的洗涤物L有没有需要进行修正的大小的偏倚(步骤S8)。Based on the detection result obtained by the rotational speed reading device 39 in step S7, the control unit 30 determines whether the deviation of the rotational speed of the rotor 20 during the one rotation is larger than a predetermined value or more, specifically, the maximum value Tmax and the minimum value Tmin of the rotational speed. Whether or not the difference is 3 rpm or more, it is judged whether or not the laundry L in the drum 4 is biased in size (step S8).

当最大值Tmax和最小值Tmin的差不到3rpm时(在步骤S8中为“否”)，控制部30判断在滚筒4内没有需要进行修正的大小的偏倚，将电机6的转速从目前为止的100rpm提高并且开始脱水运转(步骤S9)。由此，洗涤运转从漂洗过程转到脱水过程。在脱水运转中，滚筒4通过脱水旋转，用离心力使水分从洗涤物L中飞出。When the difference between the maximum value Tmax and the minimum value Tmin is less than 3 rpm (NO in step S8), the control unit 30 determines that there is no bias in the size of the drum 4 that needs to be corrected, and the rotation speed of the motor 6 is now The 100 rpm is increased and the dehydration operation is started (step S9). Thereby, the washing operation is transferred from the rinsing process to the dehydration process. In the dehydrating operation, the drum 4 is rotated by dehydration, and the water is released from the laundry L by centrifugal force.

另一方面，当最大值Tmax和最小值Tmin的差在3rpm以上时(在步骤S8中为“是”)，控制部30判断在滚筒4内存在需要进行修正的大小的偏倚，使判断次数加1(+1)(步骤S10)。On the other hand, when the difference between the maximum value Tmax and the minimum value Tmin is 3 rpm or more (YES in step S8), the control unit 30 determines that there is a bias in the size of the drum 4 that needs to be corrected, so that the number of determinations is increased. 1 (+1) (step S10).

然后，当加1后的判断次数没有达到规定次数(这里为7次)(在步骤S11中为“否”)、并且是奇数时(在步骤S12中为“是”)，控制部30进行用于修正的第一修正处理以使偏倚减少。因此，当判断次数为第一次时，就进行第一修正处理。Then, when the number of determinations after the addition of 1 has not reached the predetermined number of times (here, 7 times) (NO in step S11) and is odd (YES in step S12), the control unit 30 performs the use. The corrected first correction process is to reduce the bias. Therefore, when the number of determinations is the first time, the first correction processing is performed.

作为第一修正处理，具体地说，首先，在时间图的定时T₃处，控制部30通过使设置于洗衣机1的制动单元(未图示)工作而对电机6的转子20施加制动，在时间图的定时T₄～T₅期间，使电机6停止(步骤S13)。这里的停止，不是减缓转子20的旋转，而是使转子20的旋转完全停止。由此，由于对滚筒4的旋转进行紧急制动，因其反作用而会施加冲击给滚筒4内的洗涤物L，因此在滚筒4内使洗涤物L分散开，能够一定程度地消除偏倚。此外，作为制动单元，能够使用例如将直流电压施加给电机6的直流制动结构。Specifically, first, at the timing T ₃ of the time chart, the control unit 30 applies a brake to the rotor 20 of the motor 6 by operating a brake unit (not shown) provided in the washing machine 1 at the timing T ₃ of the time chart. At the timing T ₄ to T _{5 of the} time chart, the motor 6 is stopped (step S13). The stop here does not slow down the rotation of the rotor 20, but completely stops the rotation of the rotor 20. As a result, since the rotation of the drum 4 is urgently braked, the laundry L is applied to the drum 4 by the reaction. Therefore, the laundry L is dispersed in the drum 4, and the bias can be eliminated to some extent. Further, as the braking unit, for example, a DC braking structure that applies a DC voltage to the motor 6 can be used.

然后，控制部30在时间图的定时T₅～T₆期间，使电机6的转子20以45rpm的转速向左旋转一圈(步骤S14)，之后，在时间图的定时T₇～T₈期间，以45rpm的转速向右旋转一圈(步骤S15)。换句话说，控制部30通过进行将转子20向左右交替旋转一圈这种翻滚动作，将滚筒4的内周面的洗涤物L松散开，能够消除偏倚。Then, the control unit 30 rotates the rotor 20 of the motor 6 one turn to the left at a rotation speed of 45 rpm during the timing T ₅ to T _{6 of the} time chart (step S14), and thereafter, during the timing T ₇ to T _{8 of the} time chart. Rotate one turn to the right at 45 rpm (step S15). In other words, the control unit 30 loosens the laundry L on the inner circumferential surface of the drum 4 by performing a rolling process in which the rotor 20 is alternately rotated one by one to the right and left, thereby eliminating the bias.

控制部30在进行第一修正处理之后，在时间图的定时T₉～T₁₁期间，在进行步骤S5～S7的偏倚检测之后进行步骤S8的偏倚有无判断。当通过第一修正处理消除了偏倚时(在步骤S8中为“否”)，控制部30开始脱水运转(步骤S9)。The control unit 30 after the first correction processing is performed, the step S8 determines whether or bias after the time T ₉ ~ FIG timing period T _11, after step S5 ~ S7 bias detection. When the bias is eliminated by the first correction processing (NO in step S8), the control unit 30 starts the dehydration operation (step S9).

当通过第一修正处理没有消除偏倚时(在步骤S8中为“是”)，控制部30再次判断存在偏倚，使判断次数加1(步骤S10)。在滚筒4内的洗涤物L量多的情况下，由于洗涤物L处于以覆盖滚筒4的内周面的全部区域的方式缠绕在滚筒4上的状态，因而难以仅通过第一修正处理中的翻滚动作来消除偏倚。When the bias is not eliminated by the first correction processing (YES in step S8), the control unit 30 determines again that there is bias, and increments the number of determinations by one (step S10). In the case where the amount of the laundry L in the drum 4 is large, since the laundry L is wound on the drum 4 so as to cover the entire area of the inner circumferential surface of the drum 4, it is difficult to pass only the first correction processing. Roll over to eliminate bias.

然后，当加1后的判断次数没有达到规定次数(在步骤S11中为“否”)、并且为偶数时(在步骤S12中为“否”)，控制部30进行用于修正偏倚的第二修正处理。因此，若由针对第一次存在偏倚的判断的第一修正处理所进行的偏倚修正不充分，则控制部30根据第二次存在偏倚的判断，进行第二修正处理而非第一修正处理。Then, when the number of determinations after the addition of 1 has not reached the predetermined number of times (NO in step S11) and is even (in the case of NO in step S12), the control unit 30 performs the second for correcting the bias. Correction processing. Therefore, if the bias correction by the first correction processing for the determination of the first presence bias is insufficient, the control unit 30 performs the second correction processing instead of the first correction processing based on the determination of the second presence bias.

作为第二修正处理，具体地说，首先，在时间图的定时T₁₂～T₁₃期间，控制部30与步骤S13相同地使电机6制动停止(步骤S16)，并一定程度地修正滚筒4内的洗涤物L的偏倚。然后，控制部30将传递机构22的外轮齿轮21切换到2轴侧(步骤S17)。然后，在时间图的定时T₁₃～T₁₅期间，控制部30使电机6的转子20以124rpm的转速向右旋转2.75圈(步骤S18)。由此，转子20上直接连结的搅拌器5与转子20相同地以124rpm的转速进行旋转，另一方面滚筒4如在时间图的定时T₁₃～T₁₅期间用粗虚线所示，按照以所述的减速比进行减速后的45rpm的转速进行旋转。 Specifically, in the second correction processing, first, during the timing T ₁₂ to T _{13 of the} time chart, the control unit 30 brakes the motor 6 in the same manner as in step S13 (step S16), and corrects the drum 4 to some extent. The bias of the laundry L within. Then, the control unit 30 switches the outer ring gear 21 of the transmission mechanism 22 to the two-axis side (step S17). Then, during the timing T ₁₃ to T _{15 of the} time chart, the control unit 30 rotates the rotor 20 of the motor 6 to the right by 2.75 turns at a rotation speed of 124 rpm (step S18). Thereby, the agitator 5 directly coupled to the rotor 20 rotates at the number of revolutions of 124 rpm in the same manner as the rotor 20, and the drum 4 is indicated by a thick broken line during the timing T ₁₃ to T _{15 of the} time chart. The reduction ratio described above is rotated at a rotation speed of 45 rpm after deceleration.

由于滚筒4和搅拌器5通过像这样以相互不同的转速进行旋转，挂在滚筒4的内周面上的洗涤物L被挂在搅拌器5上的洗涤物L拉动而进行移动，从滚筒4的内周面剥离，因而能够比第一修正处理更有效地修正偏倚。之后，在时间图的定时T₁₅～T₁₆期间，控制部30与步骤S16相同地使电机6制动停止(步骤S1)，以期完全地消除洗涤物L的偏倚。Since the drum 4 and the agitator 5 are rotated at mutually different rotational speeds as described above, the laundry L hung on the inner peripheral surface of the drum 4 is pulled by the laundry L hung on the agitator 5, and is moved from the drum 4 The inner peripheral surface is peeled off, and thus the bias can be corrected more effectively than the first correction processing. Thereafter, during the timing T ₁₅ to T _{16 of the} time chart, the control unit 30 brakes the motor 6 in the same manner as in step S16 (step S1), in order to completely eliminate the bias of the laundry L.

当第二修正处理结束时，控制部30将传递机构22的外轮齿轮21切换到1轴侧(步骤S20)。When the second correction processing is completed, the control unit 30 switches the outer gear 21 of the transmission mechanism 22 to the one-axis side (step S20).

在控制部30进行第二修正处理之后，在进行步骤S5～S7的偏倚检测后进行步骤S8的偏倚有无判断。当通过第二修正处理消除了偏倚时(在步骤S8中为“否”)，控制部30开始脱水运转(步骤S9)。After the control unit 30 performs the second correction processing, the determination of the presence or absence of the deviation in step S8 is performed after performing the detection of the deviation in steps S5 to S7. When the bias is eliminated by the second correction processing (NO in step S8), the control unit 30 starts the dehydration operation (step S9).

当通过第二修正处理也没有消除偏倚时(在步骤S8中为“是”)，控制部30使判断次数加1(步骤S10)。当加1后的判断次数没有达到规定次数(在步骤S11中为“否”)、并且为奇数时(在步骤S12中为“否”)，控制部30进行第一修正处理。然后，第一修正处理和第二修正处理交替进行直到加1后的判断次数达到规定次数。When the bias is not eliminated by the second correction processing (YES in step S8), the control unit 30 increments the number of determinations by one (step S10). When the number of determinations after the addition of 1 has not reached the predetermined number of times (NO in step S11) and is an odd number (NO in step S12), the control unit 30 performs the first correction processing. Then, the first correction processing and the second correction processing are alternately performed until the number of determinations after the addition of 1 reaches a predetermined number of times.

在图3的情况下，在分别进行一次第一修正处理以及第二修正处理后，尽管第一修正处理和第二修正处理被控制为按照该顺序交替地进行，但是也可以在分别进行一次第一修正处理以及第二修正处理后，连续地只进行第一修正处理以及第二修正处理中的任一个。或者，也可以在分别进行一次第一修正处理以及第二修正处理后，将第一修正处理以及第二修正处理各自以任意的顺序以及次数进行。In the case of FIG. 3, after the first correction processing and the second correction processing are performed once, respectively, although the first correction processing and the second correction processing are controlled to be alternately performed in this order, they may be performed once. After one correction process and the second correction process, only one of the first correction process and the second correction process is continuously performed. Alternatively, after the first correction processing and the second correction processing are performed once, the first correction processing and the second correction processing may be performed in an arbitrary order and number of times.

在加1后的判断次数达到规定次数的情况下(在步骤S11中为“是”)，由于通过第一修正处理以及第二修正处理的任一个都难以消除偏倚，因而控制部30开始作为第三修正处理的不平衡修正处理(步骤S21)。When the number of determinations after the addition of 1 is a predetermined number of times (YES in step S11), since it is difficult to eliminate the bias by either of the first correction processing and the second correction processing, the control unit 30 starts as the first The imbalance correction processing of the three correction processing (step S21).

在不平衡修正处理中，控制部30通过在关闭排水阀43后打开供水阀41向滚筒4内供水到规定水位，从而将滚筒4内的洗涤物L浸到水中使其容易松开。在该状态下，控制部30通过使滚筒4以及搅拌器5旋转而将贴在滚筒4的内周面上的洗涤物L剥离并搅拌，由此消除偏倚。当不平衡修正处理结束时，控制部30进行步骤S1以后的处理。In the unbalance correction processing, the control unit 30 opens the water supply valve 41 and closes the water supply valve 41 to the predetermined water level after the drain valve 43 is closed, so that the laundry L in the drum 4 is immersed in water to be easily released. In this state, the control unit 30 rotates the drum 4 and the agitator 5 to peel off and agitate the laundry L attached to the inner circumferential surface of the drum 4, thereby eliminating the bias. When the imbalance correction process ends, control The unit 30 performs the processing in and after step S1.

如上，控制部30在洗涤物L的脱水开始(步骤S9)之前，判断滚筒4内的洗涤物L的偏倚的有无(步骤S8)。As described above, the control unit 30 determines the presence or absence of the bias of the laundry L in the drum 4 before the start of dehydration of the laundry L (step S9) (step S8).

控制部30在判断出没有发生洗涤物L的偏倚的情况下(在步骤S8中为“否”)，控制电机6以使滚筒4进行脱水旋转，开始洗涤物L的脱水(步骤S9)。由此，不会徒劳地进行用于消除洗涤物L的偏倚的处理，迅速地开始洗涤物L的脱水。When the control unit 30 determines that the deviation of the laundry L has not occurred (NO in step S8), the motor 6 is controlled to rotate the drum 4 to start dehydration of the laundry L (step S9). Thereby, the process for eliminating the bias of the laundry L is not in vain, and the dehydration of the laundry L is quickly started.

另一方面，控制部30在判断出存在洗涤物L的偏倚的情况下(在步骤S8中为“是”)，控制电机6以使滚筒4和搅拌器5以相互不同的速度进行旋转(步骤S18)。由此，由于在滚筒4内偏倚的洗涤物L通过受到来自滚筒4以及搅拌器5的各自的冲击而变得容易松散开，因而能够有效地消除滚筒4内的洗涤物L的偏倚。On the other hand, when the control unit 30 determines that there is a bias of the laundry L (YES in step S8), the motor 6 is controlled to rotate the drum 4 and the agitator 5 at mutually different speeds (steps). S18). Thereby, since the laundry L which is biased in the drum 4 is easily loosened by the respective impacts from the drum 4 and the agitator 5, the deviation of the laundry L in the drum 4 can be effectively eliminated.

因此，能够有效地消除滚筒4内的洗涤物L的偏倚，并且与洗涤物L的偏倚相关联地实现洗涤时间的缩短。Therefore, the bias of the laundry L in the drum 4 can be effectively eliminated, and the shortening of the washing time can be achieved in association with the bias of the laundry L.

此外，控制部30在判断出存在洗涤物L的偏倚的情况下，首先，作为第一修正处理控制电机6以使滚筒4和搅拌器5进行等速旋转(步骤S14以及S15)。因此，如果洗涤物L的偏倚小，则只通过使滚筒4和搅拌器5进行等速旋转，就能够迅速地消除洗涤物L的偏倚。Further, when the control unit 30 determines that there is a bias of the laundry L, first, the motor 6 is controlled as the first correction processing so that the drum 4 and the agitator 5 are rotated at a constant speed (steps S14 and S15). Therefore, if the bias of the laundry L is small, the deflection of the laundry L can be quickly eliminated only by rotating the drum 4 and the agitator 5 at a constant speed.

控制部30在第一修正处理之后仍然判断存在洗涤物L的偏倚的情况下，作为第二修正处理控制电机6以使滚筒4和搅拌器5以相互不同的速度进行旋转(步骤S18)。换句话说，在洗涤物L的偏倚大到即使第一修正处理也不能消除的情况下，通过以第二修正处理使滚筒4和搅拌器5以相互不同的速度进行旋转，从而即使是大的偏倚也能够消除。When the control unit 30 still determines that there is a bias of the laundry L after the first correction processing, the control unit 30 controls the motor 6 as the second correction processing so that the drum 4 and the agitator 5 rotate at different speeds from each other (step S18). In other words, in the case where the deviation of the laundry L is so large that even if the first correction processing cannot be eliminated, the drum 4 and the agitator 5 are rotated at mutually different speeds by the second correction processing, so that even the large Bias can also be eliminated.

此外，控制部30在判断出存在洗涤物L的偏倚的情况下(在步骤S8中为“是”)，在第二修正处理中，在使滚筒4和搅拌器5以相互不同的速度进行旋转之前，对滚筒4的旋转进行紧急的制动直到滚筒4停止(步骤S16)。此外，控制部30在第二修正处理中，在使滚筒4和搅拌器5以相互不同的速度进行旋转之后，对滚筒4的旋转施加制动(步骤S19)。通过这里的制动，由于在滚筒 4内偏倚的洗涤物L通过受到制动的冲击变得更加容易松散开，因而能够更有效地消除滚筒4内的洗涤物L的偏倚。Further, when the control unit 30 determines that there is a bias of the laundry L (YES in step S8), in the second correction processing, the drum 4 and the agitator 5 are rotated at mutually different speeds. Previously, the rotation of the drum 4 is urgently braked until the drum 4 is stopped (step S16). Further, in the second correction processing, the control unit 30 applies the brake to the rotation of the drum 4 after the drum 4 and the agitator 5 are rotated at different speeds (step S19). Through the brakes here, due to the roller The inner-biased laundry L becomes easier to loosen by the impact of the brake, so that the deviation of the laundry L in the drum 4 can be more effectively eliminated.

然后，控制部30在尽管进行了第一修正处理以及第二修正处理，反复判断存在洗涤物L的偏倚的次数也达到了规定次数的情况下(在步骤S11中为“是”)，通过控制电机6以便向滚筒4内供水，使滚筒4进行旋转，从而进行最终方法的不平衡修正处理(步骤S21)。当如此处理时，在进行不平衡修正处理之前的早期阶段，能够通过第一修正处理和第二修正处理消除绝大多数的偏倚。Then, when the first correction process and the second correction process are performed, the control unit 30 repeatedly determines that the number of times the laundry L has been biased has reached the predetermined number of times (YES in step S11), and controls The motor 6 supplies water to the inside of the drum 4 to rotate the drum 4, thereby performing an imbalance correction process of the final method (step S21). When this is done, most of the bias can be eliminated by the first correction process and the second correction process at an early stage before the imbalance correction process is performed.

此外，通过避免不必要的不平衡修正处理，能够抑制不平衡修正处理所需要的水的消耗量，并且实现时间的缩短。另一方面，在洗涤物L的偏倚大到以规定次数反复判断存在洗涤物L的偏倚的情况下，通过不平衡修正处理，能够有效地松散洗涤物L，可靠地消除洗涤物L的偏倚。Further, by avoiding the unnecessary imbalance correction processing, it is possible to suppress the amount of water consumption required for the imbalance correction processing, and to realize the shortening of the time. On the other hand, when the bias of the laundry L is so large that it is repeatedly determined that the laundry L is biased a predetermined number of times, the laundry L can be effectively loosened by the imbalance correction process, and the deviation of the laundry L can be reliably eliminated.

此外，虽然成为判断是否进行不平衡修正处理时的基准的步骤S11中的规定次数在该实施方式中为7次，然而也可以任意地设定。例如，在将该规定次数设为2次，将第一修正处理以及第二修正处理按顺序分别进行一次，即使这样偏倚的修正也仍然不充分的情况下，也可以进行不平衡修正处理。In addition, although the predetermined number of times in the step S11 for determining whether or not to perform the imbalance correction processing is seven times in the embodiment, it may be arbitrarily set. For example, when the predetermined number of times is set to two times, the first correction processing and the second correction processing are performed once in order, and even if the correction of such bias is still insufficient, the imbalance correction processing may be performed.

接下来，参照图5以后的各图，关于经过漂洗过程的最终阶段和脱水过程的初始阶段的洗涤运转的流程的变形例进行说明。此外，在图5以后的各图中，在与图3的处理步骤相同的处理步骤中，赋予与图3相同的步骤编号，省略关于其处理步骤的详细说明。Next, a modification of the flow of the washing operation through the final stage of the rinsing process and the initial stage of the dehydration process will be described with reference to the respective drawings of FIG. It is to be noted that the same steps as those in FIG. 3 are given to the same steps as those in FIG. 3, and detailed descriptions of the processing steps are omitted.

在从步骤S16到S19的第二修正处理中，如图5所示，作为步骤S18，也可以使电机6以相同的转速向左旋转2.75圈，代替在所述的步骤S18中使电机6以124rpm的转速向右旋转2.75圈，。In the second correction processing from steps S16 to S19, as shown in FIG. 5, as step S18, the motor 6 may be rotated to the left by 2.75 turns at the same rotational speed instead of causing the motor 6 to be in the above-described step S18. The speed of 124 rpm is rotated 2.75 turns to the right.

此外，在第二修正处理中，如图6所示，在步骤S17的处理之后，控制部30也可以确认在上次的第二修正处理中电机6是否进行了左旋转(步骤S22)。在这种情况下，当上次电机6进行了左旋转时(在步骤S22中为“是”)，控制部30使电机6以124rpm的转速向右旋转2.75圈(步骤S18)，当上次电机6进行了右旋转时(在步骤S22中为“否”)，控制部30使电机6以124rpm的转速向左旋转2.75圈(步骤S18)。由此，通过上次的第二修正处理和这次的第二修正处理，能够使电机6向左右交替旋转，将洗涤物L更有效地松散开。Further, in the second correction processing, as shown in FIG. 6, after the processing of step S17, the control unit 30 may confirm whether or not the motor 6 has performed the left rotation in the previous second correction processing (step S22). In this case, when the last rotation of the motor 6 is performed (YES in step S22), the control unit 30 causes the motor 6 to rotate right by 2.75 turns at a rotation speed of 124 rpm (step S18), when the last time When the motor 6 is rotated rightward (NO in step S22), the control unit 30 rotates the motor 6 to the left by 2.75 turns at a rotation speed of 124 rpm (step S18). Thus, the last second correction process and the second repair this time The positive treatment can alternately rotate the motor 6 to the left and right to loosen the laundry L more effectively.

在图7所示的变形例的情况下，在第二修正处理中，与图3的情况相同，控制部30在步骤S1～S4之后，在进行步骤S5～S7的偏倚检测之后进行步骤S8的偏倚有无判断。当控制部30判断没有发生偏倚时(在步骤S8中为“否”)，开始脱水运转(步骤S9)，当判断存在偏倚时(步骤S8中为“是”)，使判断次数加1(步骤S10)。In the case of the modification shown in FIG. 7, in the second correction processing, as in the case of FIG. 3, the control unit 30 performs the step S8 after performing the bias detection of steps S5 to S7 after steps S1 to S4. Whether there is judgment on bias. When the control unit 30 determines that no bias has occurred (NO in step S8), the dehydration operation is started (step S9), and when it is judged that there is bias (YES in step S8), the number of determinations is incremented by one (step S10).

但是，在图7的变形例中，在加1后的判断次数没有达到规定次数的情况下(在步骤S11中为“否”)，控制部30不进行步骤S12(参照图3)的判断，进行步骤S13～S15的第一修正处理，之后，继续进行步骤S16～S19的第二修正处理。之后，控制部30在将传递机构22的外轮齿轮21切换到1轴侧之后(步骤S20)，返回步骤S5。在这种情况下，当存在偏倚时，通过连续进行第一修正处理以及第二修正处理，能够迅速并且有效地消除偏倚。此外，能够实现进一步的时间缩短。However, in the modification of FIG. 7, when the number of determinations after the addition of 1 has not reached the predetermined number of times (NO in step S11), the control unit 30 does not perform the determination of step S12 (see FIG. 3). The first correction processing of steps S13 to S15 is performed, and thereafter, the second correction processing of steps S16 to S19 is continued. After that, the control unit 30 switches the outer ring gear 21 of the transmission mechanism 22 to the one-axis side (step S20), and returns to step S5. In this case, when there is a bias, the bias can be quickly and effectively eliminated by continuously performing the first correction processing and the second correction processing. In addition, further time reduction can be achieved.

在图8所示的变形例的情况下，与图3的情况相同，控制部30在进行步骤S5～S7的偏倚检测之后进行步骤S8的偏倚有无判断，当判断没有发生偏倚时(在步骤S8中为“否”)，开始脱水运转(步骤S9)，当判断存在偏倚时(在步骤S8中为“是”)，使判断次数加1(步骤S10)。In the case of the modification shown in FIG. 8, the control unit 30 performs the determination of the bias of step S8 after performing the bias detection of steps S5 to S7, and determines that there is no bias (in the step). If "NO" in S8, the dehydration operation is started (step S9), and when it is judged that there is a bias (YES in step S8), the number of determinations is incremented by one (step S10).

但是，在图8的变形例中，在加1后的判断次数没有达到规定次数的情况下(在步骤S11中为“否”)，控制部30先进行步骤S16～S19的第二修正处理，之后，在将传递机构22的外轮齿轮21切换到1轴侧之后(步骤S20)，进行步骤S14～S15的第一修正处理。在这种情况下，由于从最初开始通过第二修正处理能够迅速地消除在第一修正处理中不能消除的大小的偏倚，不需要按顺序经过第一修正处理以及第二修正处理，因而能够实现进一步的时间缩短。此外，在图7以及图8的任一变形例中，作为第二修正处理，也可以进行以图5或图6来说明了的处理。However, in the modification of FIG. 8, when the number of determinations after the addition of 1 has not reached the predetermined number of times (NO in step S11), the control unit 30 first performs the second correction processing of steps S16 to S19. After that, after the external gear 21 of the transmission mechanism 22 is switched to the one-axis side (step S20), the first correction processing of steps S14 to S15 is performed. In this case, since the size correction which cannot be eliminated in the first correction processing can be quickly eliminated by the second correction processing from the beginning, it is not necessary to pass the first correction processing and the second correction processing in order, and thus it is possible to realize Further time is shortened. Further, in any of the modifications of FIGS. 7 and 8, the processing described with reference to FIG. 5 or FIG. 6 may be performed as the second correction processing.

本发明不局限于以上进行了说明的实施方式，可以在权利要求记载的范围内进行各种变更。The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the claims.

例如，在以上的说明中，关于经过漂洗过程的最终阶段和脱水过程的初始阶段的运转的流程进行了说明，然而脱水过程之外，在漂洗过程的最终阶段中进行脱水运转的情况下，在漂洗过程的最终阶段的脱水运转中，也可以进行以上说明了的的图3或图5～图8的处理。For example, in the above description, regarding the final stage of the rinsing process and the initial stage of the dehydration process The flow of the operation of the stage has been described. However, in the case of the dehydration operation in the final stage of the rinsing process, in the dehydration operation in the final stage of the rinsing process, FIG. 3 described above may be performed. Or the processing of FIGS. 5 to 8.

此外，作为偏倚检测的一个环节在步骤S6中使电机6的转子20旋转时的100rpm这一转速，只是一个例子，当洗涤物L通过滚筒4旋转时的离心力被推到滚筒4的内周面上时，也可以是200rpm或400rpm这样的更高的转速。此外，由于在步骤S14或S15中的45rpm这一转速也只是一个例子，因而能够根据需要进行任意变更。Further, as a link of the bias detection, the rotation speed of 100 rpm when the rotor 20 of the motor 6 is rotated in step S6 is only an example, and the centrifugal force when the laundry L is rotated by the drum 4 is pushed to the inner circumferential surface of the drum 4. On the top, it can also be a higher rotation speed of 200 rpm or 400 rpm. Further, since the rotation speed of 45 rpm in step S14 or S15 is only an example, it can be arbitrarily changed as needed.

此外，在以上的实施方式中，为了使滚筒4和搅拌器5进行等速旋转、和以相互不同的速度进行相对旋转，使用了传递机构22以及齿轮切换装置7。也可以通过将电机6分别设置为滚筒4用和搅拌器5用来代替传递机构22以及齿轮切换装置7，使滚筒4以及搅拌器5通过各自的专用电机独立进行旋转，控制部30控制各专用电机的转速，从而自由地调整滚筒4以及搅拌器5各自的转速。Further, in the above embodiment, the transmission mechanism 22 and the gear switching device 7 are used in order to rotate the drum 4 and the agitator 5 at a constant speed and to rotate relative to each other at different speeds. It is also possible to arrange the motor 6 for the drum 4 and the agitator 5 instead of the transmission mechanism 22 and the gear switching device 7, so that the drum 4 and the agitator 5 are independently rotated by the respective dedicated motors, and the control unit 30 controls each dedicated The rotational speed of the motor, thereby freely adjusting the respective rotational speeds of the drum 4 and the agitator 5.

此外，虽然以上实施方式的滚筒4倾斜地配置成能够以在相对于水平方向H的倾斜方向K上延伸的轴线13为中心进行旋转，但是也可通过使轴线13在水平方向H上延伸而水平地配置滚筒4。Further, although the drum 4 of the above embodiment is obliquely arranged to be rotatable about the axis 13 extending in the oblique direction K with respect to the horizontal direction H, it is also possible to horizontally extend the axis 13 in the horizontal direction H. The drum 4 is disposed.

此外，洗衣机1也可以是具备洗涤物L的烘干功能的洗涤烘干机。Further, the washing machine 1 may be a washing and drying machine having a drying function of the laundry L.
