Description

滚筒式洗衣机Drum washing machine

技术领域Technical field

本发明涉及一种滚筒式洗衣机。这种滚筒式洗衣机既可以从洗涤到烘干连续地进行，也可以进行洗涤但不进行烘干。The present invention relates to a drum type washing machine. Such a drum type washing machine can be continuously performed from washing to drying, or can be washed without drying.

背景技术Background technique

以往，滚筒式洗衣机使横轴式滚筒在底部蓄有水的外筒内旋转，并通过设置在滚筒内的提升筋使洗涤物升起并落下，将洗涤物摔到滚筒的内周面，由此对洗涤物进行洗涤。如此，在通过提升筋来搅拌洗涤物的结构中，洗涤物之间难以互相缠绕或互相摩擦。因此，在滚筒式洗衣机中，为了提高清洗性能，可以采用在滚筒的后表面设置具有多个突条部的旋转体，并在洗涤、漂洗时，使滚筒和旋转体以不同的转速独立旋转的结构(参照专利文献1)。Conventionally, a drum type washing machine rotates a horizontal axis drum in an outer cylinder in which water is stored at the bottom, and raises and falls the laundry by a lifting rib provided in the drum, and falls the laundry onto the inner circumferential surface of the drum. This washes the laundry. Thus, in the structure in which the laundry is stirred by the lifting ribs, it is difficult for the laundry to entangle or rub against each other. Therefore, in the drum type washing machine, in order to improve the cleaning performance, a rotating body having a plurality of ridge portions may be provided on the rear surface of the drum, and the drum and the rotating body may be independently rotated at different rotation speeds during washing and rinsing. Structure (refer to Patent Document 1).

发明内容Summary of the invention

发明所要解决的问题Problems to be solved by the invention

在上述滚筒式洗衣机中，在洗涤、漂洗时，旋转体以与滚筒的转速不同的转速进行旋转，因此，在滚筒内洗涤物容易扭曲，容易产生洗涤物的布缠绕。In the above-described drum type washing machine, the rotating body rotates at a rotation speed different from the rotation speed of the drum during washing and rinsing. Therefore, the laundry in the drum is easily twisted, and the cloth of the laundry is easily entangled.

发明人等观察了滚筒内的洗涤物的运动，其结果是，当产生这样的布缠绕时，产生如下洗涤物的运动：在滚筒内，通过旋转体的旋转，互相缠绕的洗涤物被卷入到旋转体的中央部，并被推出到旋转体的轴线上。当产生这样的洗涤物的运动时，根据投入滚筒内的洗涤物的量等，能变成如下状态：互相缠绕的洗涤物聚集于滚筒的中心部分，在覆盖滚筒前表面的门与旋转体之间堆积并压缩有大量的洗涤物。如此一来，由洗涤物产生的大负荷容易施加于旋转体，容易导致驱动旋转体的驱动电机的锁死。The inventors observed the movement of the laundry in the drum, and as a result, when such a cloth is wound, the movement of the laundry is generated in which the laundry which is intertwined by the rotation of the rotating body is caught in the drum. It is to the central portion of the rotating body and is pushed out onto the axis of the rotating body. When such a movement of the laundry is generated, depending on the amount of the laundry to be fed into the drum, etc., it can be changed to the following state: intertwined The laundry collects in the central portion of the drum, and a large amount of laundry is accumulated and compressed between the door covering the front surface of the drum and the rotating body. As a result, a large load generated by the laundry is easily applied to the rotating body, and the driving motor that drives the rotating body is easily locked.

本发明是鉴于这种问题而完成的发明，其目的在于，提供一种能期待防止由于布缠绕等导致的驱动电机的锁死的滚筒式洗衣机。The present invention has been made in view of such a problem, and an object thereof is to provide a drum type washing machine which can be expected to prevent locking of a drive motor due to winding of a cloth or the like.

用于解决问题的方案Solution to solve the problem

本发明的主要方案的滚筒式洗衣机具备：外筒，配置于机壳内；滚筒，配置于所述外筒内，并能以水平轴或相对于水平方向倾斜的倾斜轴为中心进行旋转；旋转体，配置于所述滚筒内，并在表面具有与洗涤物接触的突状部；驱动部，包括驱动电机，能进行基于第一驱动方式的动作和基于第二驱动方式的动作，其中，所述第一驱动方式是将该驱动电机的转矩传递给所述滚筒以及所述旋转体，并使所述滚筒和所述旋转体以彼此不同的转速进行旋转的方式，所述第二驱动方式是将所述驱动电机的转矩不传递给所述滚筒而传递给所述旋转体，并使所述旋转体进行旋转的方式；以及控制部，控制所述驱动部的动作。此处，所述控制部在洗涤过程和/或漂洗过程中，通过所述第一驱动方式使所述滚筒以及所述旋转体正转或反转，基于接受到规定的契机输入，通过所述第二驱动方式使所述旋转体正转或反转。A drum type washing machine according to a main aspect of the present invention includes: an outer cylinder disposed in the casing; a drum disposed in the outer cylinder and rotatable about a horizontal axis or an inclined axis inclined with respect to a horizontal direction; a body disposed in the drum and having a protrusion on the surface in contact with the laundry; the driving portion including a driving motor capable of performing an action based on the first driving mode and an action based on the second driving mode, wherein The first driving method is a mode in which the torque of the driving motor is transmitted to the drum and the rotating body, and the drum and the rotating body are rotated at different rotational speeds from each other, and the second driving method A mode in which the torque of the drive motor is not transmitted to the drum and transmitted to the rotating body to rotate the rotating body, and a control unit controls the operation of the driving unit. Here, the control unit rotates the drum and the rotating body forward or reverse by the first driving method during the washing process and/or the rinsing process, and receives the predetermined trigger input through the The second driving mode causes the rotating body to rotate forward or reverse.

根据上述结构，即使由于滚筒内的洗涤物的布缠绕等而导致施加于旋转体的负荷变大，通过第二驱动方式使旋转体正转或反转，从而也会解开洗涤物，并减轻施加于驱动电机的负荷。由此，能期待防止驱动电机的锁死。According to the above configuration, even if the load applied to the rotating body becomes large due to the cloth winding or the like of the laundry in the drum, the rotating body is rotated forward or reverse by the second driving method, and the laundry is also unwound and lightened. The load applied to the drive motor. Therefore, it is expected to prevent the lock of the drive motor.

在本方案的滚筒式洗衣机中，将表示施加于所述驱动电机的负荷超过规定的大小的输入可以作为所述契机输入。In the drum type washing machine of the present embodiment, an input indicating that the load applied to the drive motor exceeds a predetermined size can be input as the trigger.

根据上述结构，仅在施加于驱动电机的负荷变大而使必要性变高的情况下，进行第二驱动方式的洗涤物的解开。由此，洗涤过程、漂洗过程难以不必要地延长。According to the above configuration, when the load applied to the drive motor is increased and the necessity is increased, the laundry of the second drive method is released. Thereby, the washing process and the rinsing process are difficult to unnecessarily extend.

在本方案的滚筒式洗衣机中，将表示所述第一驱动方式的所述滚筒以及所述旋转体的旋转开始后经过了规定时间的输入可以作为所述契机输入。In the drum type washing machine of the present aspect, an input that has passed the predetermined time after the rotation of the drum of the first driving method and the rotation of the rotating body is started can be input as the trigger.

根据上述结构，洗涤过程、漂洗过程中，在适当的时机进行第二驱动方式的洗涤物的解开，因此，可以不设置用于检测施加于驱动电机的负荷的检测部。According to the above structure, during the washing process and the rinsing process, the second driving mode is performed at an appropriate timing. The laundry is unwound, and therefore, the detecting portion for detecting the load applied to the driving motor may not be provided.

在本方案的滚筒式洗衣机中，可以设为如下结构，即，所述驱动部能进行基友第三驱动方式的动作，所述第三驱动方式是将所述驱动电机的转矩传递给所述滚筒以及所述旋转体，并使所述滚筒和所述旋转体以彼此相等的转速一体地进行旋转的方式。In the drum type washing machine of the present aspect, the drive unit can perform the operation of the third drive mode of the base, and the third drive mode transmits the torque of the drive motor to the drive unit. The drum and the rotating body are configured such that the drum and the rotating body are integrally rotated at equal rotational speeds.

在设为这种结构的情况下，可以设为如下结构，即，所述控制部在通过所述第二驱动方式使所述旋转体进行旋转之后，再次通过所述第一驱动方式使所述滚筒以及所述旋转体进行旋转之前，通过所述第三驱动方式使所述滚筒以作用于所述滚筒内的洗涤物的离心力大于重力的转速进行旋转。In the case of such a configuration, the control unit may perform the rotation by the first driving method after the rotating body is rotated by the second driving method. Before the drum and the rotating body are rotated, the drum is rotated by the third driving method such that the centrifugal force acting on the laundry in the drum is greater than the speed of gravity.

根据上述结构，能通过离心力将解开的洗涤物向外侧推开，能使其向滚筒的内周面侧分散。由此，会进一步减轻通过旋转体施加于驱动电机的负荷，会进一步抑制驱动电机的锁死。According to the above configuration, the unwound laundry can be pushed outward by centrifugal force, and can be dispersed toward the inner peripheral surface side of the drum. Thereby, the load applied to the drive motor by the rotating body is further reduced, and the locking of the drive motor is further suppressed.

在本方案的滚筒式洗衣机中，可以设为如下结构，即，所述驱动部包括：第一旋转轴，固定于所述旋转体；第二旋转轴，固定于所述滚筒；第一带轮，固定于所述第一旋转轴，并经由第一传动带连结于所述驱动电机；第二带轮，经由第二传动带连结于所述驱动电机，外径与所述第一带轮不同；以及离合器机构部，通过以所述第二带轮的旋转能传递给所述第二旋转轴的方式将所述第二旋转轴与所述第二带轮连结，将基于所述驱动部的驱动方式切换至所述第一驱动方式，通过将所述第二旋转轴与所述第一带轮以及所述第二带轮的任一个均不连结，将基于所述驱动部的驱动方式切换至所述第二驱动方式，通过以所述第一带轮的旋转能传递给所述第二旋转轴的方式将所述第二旋转轴与所述第一带轮连结，将基于所述驱动部的驱动方式切换至所述第三驱动方式。In the drum type washing machine of the present aspect, the driving unit may include a first rotating shaft fixed to the rotating body, a second rotating shaft fixed to the drum, and a first pulley. Fixed to the first rotating shaft and coupled to the driving motor via a first transmission belt; the second pulley is coupled to the driving motor via a second transmission belt, the outer diameter being different from the first pulley; a clutch mechanism portion that couples the second rotating shaft to the second pulley so that the rotation of the second pulley is transmitted to the second rotating shaft, and the driving method based on the driving portion Switching to the first driving mode, by connecting the second rotating shaft to any of the first pulley and the second pulley, switching the driving method based on the driving portion to the a second driving method for coupling the second rotating shaft to the first pulley by transmitting the rotational energy of the first pulley to the second rotating shaft, based on the driving portion Driving mode is switched to the third driving side .

根据上述结构，通过使用了借助于传动带和带轮的减速机构的简单结构，实现了采取第一驱动方式、第二驱动方式以及第三驱动方式这三种驱动方式的驱动部，因此，与使用了借助于齿轮的减速机构的情况相比，在故障等方面，能提高驱动部的可靠性。According to the above configuration, by using a simple structure of the speed reduction mechanism by means of the belt and the pulley, the drive unit adopting the three drive modes of the first drive mode, the second drive mode, and the third drive mode is realized, and thus, Compared with the case of the speed reduction mechanism of the gear, the reliability of the drive unit can be improved in terms of failure or the like.

具体实施方式detailed description

以下，参照附图，对本发明的滚筒式洗衣机的一实施方式即不具有烘干功能的滚筒式洗衣机进行说明。Hereinafter, a drum type washing machine which does not have a drying function, which is one embodiment of the drum type washing machine of the present invention, will be described with reference to the drawings.

图1是表示本实施方式的滚筒式洗衣机1的结构的侧剖图。FIG. 1 is a side cross-sectional view showing a configuration of a drum type washing machine 1 of the present embodiment.

滚筒式洗衣机1具备构成外观的机壳10。机壳10的前表面10a从中央部到上部倾斜，在倾斜的面形成有洗涤物的投入口11。投入口11由自由开闭的门12覆盖。The drum type washing machine 1 is provided with a casing 10 that constitutes an appearance. The front surface 10a of the casing 10 is inclined from the center portion to the upper portion, and an input port 11 for laundry is formed on the inclined surface. The inlet 11 is covered by a door 12 that is freely opened and closed.

在机壳10内，外筒20由多个阻尼器21弹性支承。在外筒20内，自由旋转地配置有滚筒22。外筒20以及滚筒22以后表面侧低的方式相对于水平方向倾斜。由此，滚筒22以相对于水平方向倾斜的倾斜轴为中心进行旋转。外筒20以及滚筒22的倾斜角度可以设为10～20度左右。外筒20的前表面的开口部20a以及滚筒22的前表面的开口部22a与投入口11对置，并与投入口11一起由门12关闭。在滚筒22的周壁，形成有许多脱水孔22b。而且，在滚筒22的内周面，沿周向以大致相等的间隔设置有三个提升筋23。In the casing 10, the outer cylinder 20 is elastically supported by a plurality of dampers 21. A drum 22 is rotatably disposed in the outer cylinder 20. The outer cylinder 20 and the drum 22 are inclined in a horizontal direction with respect to the horizontal direction. Thereby, the drum 22 rotates centering on the inclination axis inclined with respect to the horizontal direction. The inclination angle of the outer cylinder 20 and the drum 22 can be set to about 10 to 20 degrees. The opening 20a of the front surface of the outer cylinder 20 and the opening 22a of the front surface of the drum 22 face the input port 11, and are closed by the door 12 together with the input port 11. On the peripheral wall of the drum 22, a plurality of dehydration holes 22b are formed. Further, on the inner circumferential surface of the drum 22, three lifting ribs 23 are provided at substantially equal intervals in the circumferential direction.

在滚筒22的后部，自由旋转地配置有旋转翼24。旋转翼24具有大致圆盘形状。在旋转翼24的表面，形成有从中央部呈放射状延伸的多个突状部24a。旋转翼24与滚筒22同轴进行旋转。需要说明的是，旋转翼24相当于本发明的旋转体。 A rotary wing 24 is rotatably disposed at a rear portion of the drum 22. The rotary wing 24 has a substantially disc shape. A plurality of projecting portions 24a radially extending from the center portion are formed on the surface of the rotor blade 24. The rotary wing 24 rotates coaxially with the drum 22. It should be noted that the rotor blade 24 corresponds to the rotating body of the present invention.

在外筒20的后方，配置有产生驱动滚筒22以及旋转翼24的转矩的驱动部30。在洗涤过程以及漂洗过程时，驱动部30使滚筒22以及旋转翼24在同一方向以不同的转速进行旋转。A drive unit 30 that generates torque for driving the drum 22 and the rotary vane 24 is disposed behind the outer cylinder 20. During the washing process and the rinsing process, the driving unit 30 rotates the drum 22 and the rotating blades 24 at different rotational speeds in the same direction.

具体而言，驱动部30使滚筒22以施加于滚筒22内的洗涤物的离心力小于重力的转速进行旋转，并使旋转翼24以比滚筒22的转速快的转速进行旋转。Specifically, the drive unit 30 rotates the drum 22 at a number of revolutions in which the centrifugal force applied to the laundry in the drum 22 is less than the gravity, and rotates the rotor 24 at a number of revolutions faster than the number of rotations of the drum 22.

另一方面，在脱水过程时，驱动部30使滚筒22以及旋转翼24以施加于滚筒22内的洗涤物的离心力远远大于重力的转速一体地进行旋转。驱动部30的详细结构随后进行说明。On the other hand, at the time of the dehydration process, the drive unit 30 integrally rotates the drum 22 and the rotary vane 24 with the centrifugal force of the laundry applied to the drum 22 being much larger than the rotational speed of gravity. The detailed structure of the drive unit 30 will be described later.

在外筒20的底部，形成有排水口部20b。在排水口部20b设置有排水阀40。排水阀40连接于排水软管41。当排水阀40被打开时，蓄于外筒20内的水就会通过排水软管41向机体外部排出。A drain port portion 20b is formed at the bottom of the outer cylinder 20. A drain valve 40 is provided in the drain port portion 20b. The drain valve 40 is connected to the drain hose 41. When the drain valve 40 is opened, the water stored in the outer cylinder 20 is discharged to the outside of the body through the drain hose 41.

在机壳10内的前方上部，配置有洗涤剂盒50。容纳有洗涤剂的洗涤剂容器50a从前方自由抽出地容纳于洗涤剂盒50。洗涤剂盒50通过给水软管52连接于配置在机壳10内的后方上部的给水阀51。此外，洗涤剂盒50通过注水管53连接于外筒20的上部。当给水阀51被打开时，自来水从水龙头通过给水软管52、洗涤剂盒50以及注水管53供给至外筒20内。此时，容纳在洗涤剂容器50a中的洗涤剂被水冲走而供给至外筒20内。A detergent box 50 is disposed in the front upper portion of the casing 10. The detergent container 50a containing the detergent is accommodated in the detergent box 50 freely withdrawn from the front. The detergent box 50 is connected to the water supply valve 51 disposed at the upper rear portion in the casing 10 through the water supply hose 52. Further, the detergent box 50 is connected to the upper portion of the outer cylinder 20 through a water injection pipe 53. When the water supply valve 51 is opened, tap water is supplied from the faucet into the outer cylinder 20 through the water supply hose 52, the detergent box 50, and the water injection pipe 53. At this time, the detergent contained in the detergent container 50a is washed away by water and supplied into the outer cylinder 20.

接着，对驱动部30的结构进行详细说明。Next, the configuration of the drive unit 30 will be described in detail.

The rotation of the drive motor 100 is decelerated in accordance with a reduction ratio determined by the outer diameter ratio of the wing pulley 510 and the first motor pulley 520, and is transmitted to the wing shaft 300 and the drum shaft 200.

翼带轮510由翼轴300的后端部自由旋转地支承。在翼带轮510中，在中央部形成有供翼轴300***的***孔511。将翼轴300的后端部******孔511，并通过使用了花键的压入等规定的固定方法，将翼轴300的后端部固定于***孔511。此外，通过安装于翼轴300的后端部的固定螺钉320，防止翼带轮510向后方脱落。The wing pulley 510 is rotatably supported by the rear end portion of the wing shaft 300.

滚筒带轮610形成为前表面打开的碟状，包括带轮部611和外径小于带轮部611的固定部612。由于带轮部611的外径、即滚筒带轮610的外径大于翼带轮510的外径，因此，滚筒减速机构600的减速比大于翼减速机构500的减速比。例如，滚筒减速机构600的减速比可以设为翼减速机构500的减速比的约2倍。The drum pulley 610 is formed in a dish shape in which the front surface is opened, and includes a pulley portion 611 and a fixing portion 612 having an outer diameter smaller than that of the pulley portion 611. Since the outer diameter of the pulley portion 611, that is, the outer diameter of the drum pulley 610 is larger than the outer diameter of the wing pulley 510, the reduction ratio of the drum reduction mechanism 600 is greater than the reduction ratio of the wing reduction mechanism 500. For example, the reduction ratio of the drum reduction mechanism 600 may be set to be about twice the reduction ratio of the wing reduction mechanism 500.

在固定部612，在中央部形成有***孔613。在该***孔613与滚筒轴200之间夹有前后两个滚动轴承614、615。通过两个滚动轴承614、615，滚筒带轮610相对于滚筒轴200顺畅地进行旋转。In the fixing portion 612, an insertion hole 613 is formed in the center portion. Two front and rear rolling

The insertion hole 712 is passed through the drum shaft 200, and the clutch guide 710 is fixed to the drum shaft 200 by a fixing method using a key groove 713 and a key (not shown). Thereby, the clutch guide 710 rotates together with the drum shaft 200.

如图6(a)所示，离合器体720包括：离合器部721、包围部722、以及滚动轴承723。离合器部721具有前表面以及后表面打开的圆筒形状。如图7(a)至图7(c)所示，在离合器部721的外周面，在前部以及后部分别遍及整个圆周形成有前花键724以及后花键725。As shown in FIG. 6(a), the clutch body 720 includes a clutch portion 721, an enclosing portion 722, and a rolling bearing 723. The clutch portion 721 has a cylindrical shape in which the front surface and the rear surface are opened. As shown in FIGS. 7(a) to 7(c), on the outer peripheral surface of the clutch portion 721, a front spline 724 and a rear spline 725 are formed on the front portion and the rear portion over the entire circumference.

离合器部721的内径设为与离合器导向件710的外径大致相等，离合器部721的前后的尺寸设为大于离合器导向件710的前后的尺寸。在离合器部721的内部，***有离合器导向件710。在离合器部721的内周面，遍及整个圆周形成有内花键726，该内花键726与离合器导向件710的花键711啮合。内花键726的前后的尺寸设为大于花键711的前后的尺寸。The inner diameter of the clutch portion 721 is substantially equal to the outer diameter of the clutch guide 710, and the front and rear dimensions of the clutch portion 721 are set to be larger than the front and rear dimensions of the clutch guide 710. A clutch guide 710 is inserted inside the clutch portion 721. Formed on the inner circumferential surface of the clutch portion 721 over the entire circumference There is an internal spline 726 that engages the spline 711 of the clutch guide 710. The front and rear dimensions of the inner splines 726 are set to be larger than the front and rear dimensions of the splines 711.

通过内花键726与花键711卡合，离合器部721变成能相对于离合器导向件710、即固定有离合器导向件710的滚筒轴200向滚筒轴200的轴线方向移动并且能与滚筒轴200一起进行旋转的状态。When the internal splines 726 are engaged with the splines 711, the clutch portion 721 becomes movable in the axial direction of the drum shaft 200 with respect to the clutch guide 710, that is, the drum shaft 200 to which the clutch guide 710 is fixed, and can be coupled to the drum shaft 200. The state of rotation together.

包围部722形成为圆环状，以离合器部721自由旋转的方式包围离合器部721的中央部。在离合器部721与包围部722之间，设置有滚动轴承723。滚动轴承723通过大小两个挡圈727、728固定为不前后移动。通过滚动轴承723，离合器部721相对于包围部722顺畅地进行旋转。The surrounding portion 722 is formed in an annular shape, and surrounds the central portion of the clutch portion 721 so that the clutch portion 721 is free to rotate. A rolling bearing 723 is provided between the clutch portion 721 and the surrounding portion 722. The rolling bearing 723 is fixed by the two sizes of the retaining rings 727, 728 so as not to move back and forth. The clutch portion 721 smoothly rotates with respect to the surrounding portion 722 by the rolling bearing 723.

离合器杆730的上端部以能相对于包围部722进行旋转的方式连结于包围部722。此外，离合器杆730自由转动地支承在设置于杆支承部740的支轴741。The upper end portion of the clutch lever 730 is coupled to the surrounding portion 722 so as to be rotatable relative to the surrounding portion 722. Further, the clutch lever 730 is rotatably supported by a support shaft 741 provided on the lever support portion 740.

离合器驱动装置750包括促动器(actuator)751和操作杆752。促动器751使操作杆752向前后移动。操作杆752连结于离合器杆730的下端部。离合器杆730的下端部能相对于操作杆752进行旋转。The clutch drive 750 includes an actuator 751 and an operating lever 752. The actuator 751 moves the operating lever 752 forward and backward. The operating lever 752 is coupled to the lower end portion of the clutch lever 730. The lower end portion of the clutch lever 730 is rotatable relative to the operating lever 752.

杆支承部740以及离合器驱动装置750固定于未图示的安装板，该安装板装接于轴承单元400、或者外筒20。The rod support portion 740 and the clutch drive device 750 are fixed to a mounting plate (not shown) that is attached to the bearing unit 400 or the outer tube 20.

在驱动部30的驱动方式从单轴驱动方式或旋转翼单体驱动方式切换至双轴驱动方式的情况下，如图2所示，操作杆752被拉入促动器751的内部。即，操作杆752向后方移动。离合器杆730的下端部***作杆752拉动而向后方移动，离合器杆730以支轴741为中心向前方进行旋转。离合器杆730的上端部向前方移动，离合器体720被离合器杆730的上端部推动而向前方移动。由此，离合器部721的前花键724与滚筒带轮610的花键617卡合。When the driving method of the driving unit 30 is switched from the single-axis driving method or the single-rotor driving method to the two-axis driving method, as shown in FIG. 2, the operating lever 752 is pulled into the inside of the actuator 751. That is, the operating lever 752 moves rearward. The lower end portion of the clutch lever 730 is pulled by the operating lever 752 to move rearward, and the clutch lever 730 is rotated forward about the spindle 741. The upper end portion of the clutch lever 730 moves forward, and the clutch body 720 is pushed by the upper end portion of the clutch lever 730 to move forward. Thereby, the front spline 724 of the clutch portion 721 is engaged with the spline 617 of the drum pulley 610.

当前花键724与花键617卡合时，离合器部721与滚筒带轮610在旋转方向上被固定，因此，变成能将滚筒带轮610的旋转经由离合器部721以及离合器导向件710传递给滚筒轴200的状态。在这样的状态下，当驱动电机100进行旋转时，该旋转经由翼减速机构500传递给翼轴300，固定于翼轴300的旋转翼24进行旋转。旋转翼24以驱动电机100的转速按照翼减速机构500的减速比降低后的转速进行旋转。此外，驱动电机100的旋转经由滚筒减速机构600 传递给滚筒轴200，固定于滚筒轴200的滚筒22进行旋转。滚筒22以驱动电机100的转速按照滚筒减速机构600的减速比降低后的转速进行旋转。如上所述，滚筒减速机构600的减速比大于翼减速机构500的减速比，因此，旋转翼24以比滚筒22快的转速在与滚筒22相同的方向进行旋转。When the current spline 724 is engaged with the spline 617, the clutch portion 721 and the drum pulley 610 are fixed in the rotational direction, and therefore, the rotation of the drum pulley 610 can be transmitted to the clutch portion 721 and the clutch guide 710 to The state of the drum shaft 200. In such a state, when the drive motor 100 rotates, the rotation is transmitted to the wing shaft 300 via the wing reduction mechanism 500, and the rotary blade 24 fixed to the wing shaft 300 rotates. The rotary wing 24 rotates at a rotational speed at which the speed of the drive motor 100 is reduced in accordance with the reduction ratio of the wing reduction mechanism 500. Further, the rotation of the drive motor 100 is via the drum reduction mechanism 600 It is transmitted to the drum shaft 200, and the drum 22 fixed to the drum shaft 200 is rotated. The drum 22 is rotated at a rotation speed at which the rotation speed of the drive motor 100 is reduced in accordance with the reduction ratio of the drum reduction mechanism 600. As described above, the reduction ratio of the drum reduction mechanism 600 is larger than the reduction ratio of the wing reduction mechanism 500, and therefore, the rotary vane 24 rotates in the same direction as the drum 22 at a higher rotational speed than the drum 22.

此处，虽然离合器部721与滚筒带轮610一起旋转，但离合器杆730连结于以自由旋转的状态连结有离合器部721的包围部722，因此，即使离合器部721进行旋转，该旋转也几乎不会传递给离合器杆730。Here, although the clutch portion 721 rotates together with the drum pulley 610, the clutch lever 730 is coupled to the enclosing portion 722 in which the clutch portion 721 is coupled to the freely rotatable state. Therefore, even if the clutch portion 721 rotates, the rotation hardly occurs. Will be transmitted to the clutch lever 730.

接着，在驱动部30的驱动方式从双轴驱动方式或旋转翼单体驱动方式切换至单轴驱动方式的情况下，如图3所示，操作杆752被从促动器751的内部向前方推出。离合器杆730的下端部***作杆752推动而向前方移动，离合器杆730以支轴741为中心向后方进行旋转。离合器杆730的上端部向后方移动，离合器体720被离合器杆730的上端部推动而向后方移动。由此，离合器部721的后花键725与翼带轮510的花键513卡合。Next, when the driving method of the driving unit 30 is switched from the two-axis driving method or the single-rotor driving method to the single-axis driving method, as shown in FIG. 3, the operating lever 752 is moved forward from the inside of the actuator 751. roll out. The lower end portion of the clutch lever 730 is pushed by the operating lever 752 to move forward, and the clutch lever 730 is rotated rearward about the spindle 741. The upper end portion of the clutch lever 730 moves rearward, and the clutch body 720 is pushed by the upper end portion of the clutch lever 730 to move rearward. Thereby, the rear spline 725 of the clutch portion 721 is engaged with the spline 513 of the wing pulley 510.

当后花键725与花键513卡合时，离合器部721与翼带轮510在旋转方向上被固定，因此，变成能将翼带轮510的旋转经由离合器部721以及离合器导向件710传递给滚筒轴200的状态。在这样的状态下，当驱动电机100进行旋转时，该旋转经由翼减速机构500传递给滚筒轴200以及翼轴300，滚筒22以及旋转翼24进行旋转。滚筒22以及旋转翼24以驱动电机100的转速按照翼减速机构500的减速比降低后的转速在相同的方向一体地进行旋转。When the rear spline 725 is engaged with the spline 513, the clutch portion 721 and the wing pulley 510 are fixed in the rotational direction, and therefore, the rotation of the wing pulley 510 can be transmitted via the clutch portion 721 and the clutch guide 710. The state of the roller shaft 200 is given. In such a state, when the drive motor 100 rotates, the rotation is transmitted to the drum shaft 200 and the wing shaft 300 via the wing reduction mechanism 500, and the drum 22 and the rotary blade 24 rotate. The drum 22 and the rotor blades 24 integrally rotate in the same direction in accordance with the number of revolutions of the drive motor 100 in accordance with the number of revolutions of the speed reduction mechanism 500.

需要说明的是，在单轴驱动方式下，当驱动电机100进行旋转时，滚筒带轮610也随着该旋转而进行旋转。然而，滚筒带轮610仅相对于滚筒轴200进行空转，滚筒带轮610的旋转不会传递给滚筒轴200。It should be noted that in the single-axis driving mode, when the driving motor 100 rotates, the drum pulley 610 also rotates in accordance with the rotation. However, the drum pulley 610 is only idling with respect to the drum shaft 200, and the rotation of the drum pulley 610 is not transmitted to the drum shaft 200.

接着，在驱动部30的驱动方式从双轴驱动方式或单轴驱动方式切换至旋转翼单体驱动方式的情况下，如图4所示，通过离合器杆730，离合器部721被移动至前花键724与滚筒带轮610的花键617不卡合、后花键725与翼带轮510也不卡合的位置。即，离合器机构部700将滚筒轴200与滚筒带轮610以及翼带轮510均不连结。Next, when the driving method of the driving unit 30 is switched from the two-axis driving method or the single-axis driving method to the single-shaft driving method, as shown in FIG. 4, the clutch portion 721 is moved to the front by the clutch lever 730. The key 724 is not engaged with the spline 617 of the drum pulley 610, and the rear spline 725 and the wing pulley 510 are not engaged. That is, the clutch mechanism unit 700 does not connect the drum shaft 200 to the drum pulley 610 and the wing pulley 510.

在这样的状态下，当驱动电机100进行旋转时，虽然旋转翼24进行旋转，但任一个带轮510、610的旋转都不会传递给滚筒轴200，因此，滚筒22不进行旋转。In such a state, when the drive motor 100 rotates, although the rotary wing 24 rotates, However, the rotation of any of the

pulleys

510, 610 is not transmitted to the drum shaft 200, and therefore, the drum 22 is not rotated.

The drain drive unit 807, the clutch drive unit 808, the door lock device 809, and the like are controlled.

那么，滚筒式洗衣机1基于用户对操作部803的操作，进行各种运转模式的洗涤运转。在洗涤运转中，按顺序执行洗涤过程、中间脱水过程、漂洗过程以及最终脱水过程。需要说明的是，根据运转模式，有时会进行两次以上中间脱水过程和漂洗过程。Then, the drum type washing machine 1 performs a washing operation in various operation modes based on the operation of the operation unit 803 by the user. In the washing operation, the washing process, the intermediate dehydration process, the rinsing process, and the final dehydration process are sequentially performed. It should be noted that depending on the operation mode, the intermediate dehydration process and the rinsing process may be performed twice or more.

在洗涤过程以及漂洗过程中，驱动部30的驱动方式被切换至双轴驱动方式。在外筒20内蓄水至不到投入口11的下边缘的规定的水位，以使滚筒22内的洗涤物浸泡在水中。然后，在这种外筒20蓄有水的状态下，作为洗涤动作或漂洗动作，驱动电机100交替进行正转或反转，滚筒22和旋转翼24以旋转翼24的转速比滚筒22的转速快的状态交替进行正转或反转。此时，滚筒22以作用于滚筒22内的洗涤物的离心力小于重力的转速进行旋转。During the washing process and the rinsing process, the driving mode of the driving portion 30 is switched to the two-axis driving mode. Water is stored in the outer cylinder 20 to a predetermined water level below the lower edge of the inlet port 11 so that the laundry in the drum 22 is immersed in water. Then, in a state where the outer cylinder 20 is filled with water, the driving motor 100 alternately performs forward rotation or reverse rotation as the washing operation or the rinsing operation, and the drum 22 and the rotary wing 24 are rotated by the rotation speed of the rotary blade 24 than the rotation speed of the drum 22. The fast state alternates forward or reverse. At this time, the drum 22 is rotated by the centrifugal force of the laundry acting on the drum 22 being less than the speed of gravity.

滚筒22内的洗涤物被提升筋23搅起并落下，由此摔到滚筒22的内周面。除此之外，在滚筒22的后部，洗涤物与旋转的旋转翼24的突状部24a接触，洗涤物被突状部24a摩擦或者洗涤物被突状部24a搅拌。由此，洗涤物被洗涤或者漂洗。The laundry in the drum 22 is stirred up by the lifting ribs 23 and dropped, thereby falling onto the inner circumferential surface of the drum 22. In addition to this, at the rear portion of the drum 22, the laundry comes into contact with the projecting portion 24a of the rotating rotor blade 24, and the laundry is rubbed by the projecting portion 24a or the laundry is stirred by the projecting portion 24a. Thereby, the laundry is washed or rinsed.

如此，在洗涤以及漂洗时，不仅由滚筒22的旋转产生的机械力、而且由旋转翼24产生的机械力也被赋予洗涤物，因此，能期待提高清洗性能。在中间脱水过程以及最终脱水过程中，驱动部30的驱动方式被切换至单轴驱动方式。作为脱水动作，驱动电机100单向地高速旋转，滚筒22以及旋转翼24以作用于滚筒22内的洗涤物的离心力远大于重力的转速一体地进行旋转。通过离心力的作用，洗涤物被按压在滚筒22的内周面而被脱水。As described above, at the time of washing and rinsing, not only the mechanical force generated by the rotation of the drum 22 but also the mechanical force generated by the rotary blade 24 is imparted to the laundry, and therefore, it is expected to improve the washing performance. In the intermediate dehydration process and the final dehydration process, the driving mode of the drive unit 30 is switched to the single-axis drive mode. As the dehydration operation, the drive motor 100 rotates at a high speed in one direction, and the drum 22 and the rotary vane 24 integrally rotate with the centrifugal force of the laundry acting on the drum 22 being much larger than the rotational speed of the gravity. By the action of the centrifugal force, the laundry is pressed against the inner peripheral surface of the drum 22 to be dehydrated.

如此，在脱水时，滚筒22和旋转翼24一体地进行旋转，因此，不会存在由旋转翼24搅拌贴于滚筒22的洗涤物这样的事情，而能良好地将洗涤物脱水。As described above, since the drum 22 and the rotary vane 24 rotate integrally when the water is dehydrated, there is no such thing as the laundry attached to the drum 22 by the rotary vane 24, and the laundry can be dehydrated satisfactorily.

需要说明的是，在本实施方式中，在单轴驱动方式中，使用减速比小于滚筒带轮610的翼带轮510。因此，与使用滚筒带轮610的情况相比，能降低脱水时的驱动电机100的转速，能抑制驱动电机100的耗电量。此外，能缩小洗涤、漂洗时的转速与脱水时的转速之差，因此，能使驱动电机100在电机高效的区域进行旋转。 In the present embodiment, in the single-shaft driving method, the wing pulley 510 having a reduction ratio smaller than that of the drum pulley 610 is used. Therefore, compared with the case where the drum pulley 610 is used, the number of rotations of the drive motor 100 at the time of dehydration can be reduced, and the power consumption of the drive motor 100 can be suppressed. Further, since the difference between the number of rotations during washing and rinsing and the number of rotations during dehydration can be reduced, the drive motor 100 can be rotated in an area where the motor is efficient.

图9是表示本实施方式的洗涤过程以及漂洗过程中的控制部801的控制动作的流程图。图10(a)是示意性地表示本实施方式的互相缠绕的洗涤物聚集于滚筒22的中心部，旋转翼24被堆积于门12与旋转翼24之间的洗涤物压迫的样子的图，图10(b)是示意性地表示本实施方式的通过解开动作使聚集于滚筒22的中心部的洗涤物解开，洗涤物之间分离的样子的图。FIG. 9 is a flowchart showing a control operation of the control unit 801 in the washing process and the rinsing process according to the present embodiment. Fig. 10 (a) is a view schematically showing a state in which the mutually entangled laundry of the present embodiment is collected in the center portion of the drum 22, and the rotating blade 24 is pressed by the laundry deposited between the door 12 and the rotary blade 24. (b) of FIG. 10 is a view schematically showing a state in which the laundry collected in the center portion of the drum 22 is unwound by the unwinding operation, and the laundry is separated from each other.

以下，参照图9至图10(b)，对洗涤过程以及漂洗过程中的控制部801的控制动作进行说明。Hereinafter, the control operation of the control unit 801 in the washing process and the rinsing process will be described with reference to FIGS. 9 to 10(b).

当洗涤过程或漂洗过程开始时，控制部801通过离合器机构部700将驱动部30的驱动方式从单轴驱动方式切换至双轴驱动方式(S101)。接着，控制部801向外筒20内进行给水(S102)。即，控制部801打开给水阀51向外筒20内供水，当外筒20内的水位达到规定水位时，关闭给水阀51停止向外筒20内供水。When the washing process or the rinsing process is started, the control unit 801 switches the driving mode of the driving unit 30 from the single-axis driving method to the two-axis driving method by the clutch mechanism unit 700 (S101). Next, the control unit 801 performs water supply to the inside of the outer cylinder 20 (S102). That is, the control unit 801 opens the water supply valve 51 to supply water into the outer cylinder 20. When the water level in the outer cylinder 20 reaches a predetermined water level, the water supply valve 51 is closed to stop the water supply to the outer cylinder 20.

当给水完成时，作为洗涤动作或漂洗动作，控制部801使驱动电机100交替进行正转或反转(S103)。例如，正转或反转的开启时间设为10～20秒左右的时间，关闭时间设定为1秒左右的时间。此外，驱动电机100以规定转速进行旋转，例如滚筒22以45rpm进行旋转，旋转翼24以90rpm进行旋转。如上所述，滚筒22以作用于滚筒22内的洗涤物的离心力小于重力的转速进行旋转，旋转翼24以高于滚筒22的转速进行旋转。洗涤物在滚筒22内一边翻滚一边被旋转翼24搅拌或摩擦。When the water supply is completed, the control unit 801 alternately performs the forward rotation or the reverse rotation of the drive motor 100 as a washing operation or a rinsing operation (S103). For example, the opening time of forward rotation or reverse rotation is set to a time of about 10 to 20 seconds, and the closing time is set to a time of about 1 second. Further, the drive motor 100 is rotated at a predetermined number of revolutions, for example, the drum 22 is rotated at 45 rpm, and the rotary vane 24 is rotated at 90 rpm. As described above, the drum 22 rotates with the centrifugal force acting on the laundry in the drum 22 being less than the rotational speed of the gravity, and the rotary vane 24 is rotated at a higher rotational speed than the drum 22. The laundry is tumbling in the drum 22 while being agitated or rubbed by the rotary wing 24.

洗涤动作或漂洗动作中，控制部801接受流经驱动电机100的驱动电流值的输入，监视所输入的驱动电流值是否超过了规定的阈值(S104)。在驱动电流值没有超过规定的阈值的情况下，如果没有经过规定的运转时间、例如20分钟(S105：否)，则继续进行洗涤动作或漂洗动作。In the washing operation or the rinsing operation, the control unit 801 receives an input of the drive current value flowing through the drive motor 100, and monitors whether or not the input drive current value exceeds a predetermined threshold (S104). When the drive current value does not exceed the predetermined threshold value, if the predetermined operation time has not elapsed, for example, 20 minutes (S105: NO), the washing operation or the rinsing operation is continued.

在洗涤、漂洗时，旋转翼24以与滚筒22的转速不同的转速进行旋转，因此，在滚筒22内洗涤物容易扭曲，容易产生洗涤物的布缠绕。当产生这样的布缠绕时，产生如下洗涤物的运动：在滚筒22内，通过旋转翼24的旋转，互相缠绕的洗涤物被卷入到旋转翼24的中央部，并被推出到旋转翼24的轴线上。当产生这样的洗涤物的运动时，在投入滚筒22内的洗涤物多的情况下，如图10(a)所示，能变成如下状态：互相缠绕的洗涤物聚集于滚筒22的中心部分，在门12与旋转翼24之间堆积并压缩有大量的洗涤物。如此一来，由洗涤物产生的大负荷容易施加于旋转翼24，大负荷容易施加于驱动电机100。During the washing and rinsing, the rotary vane 24 rotates at a rotational speed different from the rotational speed of the drum 22. Therefore, the laundry is easily twisted in the drum 22, and the cloth of the laundry is easily entangled. When such a cloth winding is generated, the movement of the laundry is generated in which, in the drum 22, the mutually wound laundry is taken up to the central portion of the rotary wing 24 by the rotation of the rotary wing 24, and is pushed out to the rotary wing 24 On the axis. When the movement of the laundry is generated, when there is a large amount of laundry to be fed into the drum 22, as shown in FIG. 10(a), it can be changed to a state in which the mutually entangled laundry gathers in the central portion of the drum 22. , A large amount of laundry is deposited and compressed between the door 12 and the rotary wing 24. As a result, a large load generated by the laundry is easily applied to the rotary blade 24, and a large load is easily applied to the drive motor 100.

如此，当由于滚筒22内的布缠绕而导致产生洗涤物对旋转翼24的压迫状态，由此大负荷施加于旋转翼24时，为了使驱动电机100以规定转速进行旋转而需要大量的驱动电流，因此，驱动电流值大于阈值。如此一来，作为契机输入，超过阈值的驱动电流值从驱动电流检测部810输入给控制部801。Thus, when the pressing state of the laundry to the rotary blade 24 is caused by the winding of the cloth in the drum 22, and thus a large load is applied to the rotary blade 24, a large amount of driving current is required in order to rotate the drive motor 100 at a predetermined rotational speed. Therefore, the drive current value is greater than the threshold. As a result, as a trigger input, the drive current value exceeding the threshold is input from the drive current detecting unit 810 to the control unit 801.

当判断为驱动电流值超过阈值时(S104：是)，控制部801结束洗涤动作或漂洗动作，通过离合器机构部700将驱动部30的驱动方式从双轴驱动方式切换至旋转翼单体驱动方式(S106)。接着，作为解开动作，控制部801使驱动电机100以短于双轴驱动方式的洗涤动作或漂洗动作的周期交替进行正转或反转(S107)。例如，正转或反转的开启时间设为0.5秒左右的时间，关闭时间设为0.5秒左右的时间。此外，驱动电机100设定为如下目标转速，例如使旋转翼24以1000r1m进行旋转。When it is determined that the drive current value exceeds the threshold value (S104: YES), the control unit 801 ends the washing operation or the rinsing operation, and the clutch mechanism unit 700 switches the drive mode of the drive unit 30 from the biaxial drive mode to the rotary wing single drive mode. (S106). Next, as the unwinding operation, the control unit 801 alternately rotates or reverses the drive motor 100 in a cycle shorter than the two-axis drive mode of the washing operation or the rinsing operation (S107). For example, the turn-on time of forward rotation or reverse rotation is set to about 0.5 second, and the shutdown time is set to about 0.5 second. Further, the drive motor 100 is set to a target rotation speed, for example, the rotary vane 24 is rotated at 1000 r1 m.

滚筒22停止的状态下，旋转翼24以短周期重复进行正转和反转。通过该旋转翼24的反转旋转动作，互相缠绕的洗涤物解开，如图10(b)所示，聚集于滚筒22的中央部的洗涤物之间分离。由此，会消除洗涤物对旋转翼24的压迫，会减轻施加于旋转翼24的负荷，会减轻施加于驱动电机100的负荷。In a state where the drum 22 is stopped, the rotary wing 24 repeats forward rotation and reverse rotation in a short cycle. By the reverse rotation operation of the rotary blade 24, the mutually entangled laundry is unwound, and as shown in FIG. 10(b), the laundry collected in the central portion of the drum 22 is separated. Thereby, the pressing of the laundry to the rotary blade 24 is eliminated, the load applied to the rotary blade 24 is reduced, and the load applied to the drive motor 100 is reduced.

当经过作为解开所需的时间预先设定的解开时间时(S108：是)，控制部801结束解开动作，通过离合器机构部700将驱动部30的驱动方式从旋转翼单体驱动方式切换至双轴驱动方式(S109)。然后，作为洗涤动作或漂洗动作，控制部801再次使驱动电机100交替进行正转或反转(S103)。需要说明的是，在进行从S106至S109的处理期间，运转时间的计时停止。When the unwrapping time set in advance as the time required for the disengagement is passed (S108: YES), the control unit 801 ends the unwinding operation, and the driving mechanism of the driving unit 30 is driven from the single rotor by the clutch mechanism unit 700. Switch to the two-axis drive mode (S109). Then, as the washing operation or the rinsing operation, the control unit 801 causes the drive motor 100 to alternately perform forward rotation or reverse rotation (S103). It should be noted that the timing of the operation time is stopped during the processing from S106 to S109.

然后，当经过运转时间时(S105：是)，控制部801结束洗涤动作或漂洗动作，打开排水阀40从外筒20内进行排水(S110)。当排水完成时，洗涤过程或漂洗过程结束。When the operation time has elapsed (S105: YES), the control unit 801 ends the washing operation or the rinsing operation, and opens the drain valve 40 to drain water from the inside of the outer cylinder 20 (S110). When the drainage is completed, the washing process or the rinsing process ends.

<实施方式的效果><Effects of Embodiments>

根据本实施方式，作为表示施加于驱动电机100的负荷超过规定的大小的契机输入，当接受到超过规定的阈值的驱动电流值时，基于此，驱动部30的驱动方式被从双轴驱动方式切换至旋转翼单体驱动方式，在滚筒22停止的状态下，旋转翼24进行正转或反转。由此，集中在滚筒22的中央部的洗涤物会解开，洗涤物之间会分离。因此，会减轻通过旋转翼24施加于驱动电机100的负荷，会抑制驱动电机100的锁死。此外，由于消除了由布缠绕导致的洗涤物的运动的恶化，因此能防止清洗性能的降低。According to the present embodiment, when a drive input value exceeding a predetermined threshold value is received as a trigger input indicating that the load applied to the drive motor 100 exceeds a predetermined magnitude, the drive unit 30 is driven based on this. The moving mode is switched from the biaxial driving mode to the rotary wing single driving mode, and the rotating blade 24 performs forward rotation or reverse rotation in a state where the drum 22 is stopped. Thereby, the laundry concentrated in the central portion of the drum 22 is unwound, and the laundry is separated. Therefore, the load applied to the drive motor 100 by the rotary wing 24 is reduced, and the lock of the drive motor 100 is suppressed. Further, since the deterioration of the movement of the laundry caused by the winding of the cloth is eliminated, the deterioration of the washing performance can be prevented.

而且，根据本实施方式，通过监视驱动电流值，检测对驱动电机100的负荷变大，因此，能仅在必要性变高的情况下进行旋转翼单体驱动方式的洗涤物的解开。由此，洗涤过程、漂洗过程难以不必要地延长。Further, according to the present embodiment, by monitoring the drive current value, it is detected that the load on the drive motor 100 is increased. Therefore, it is possible to perform the unwinding of the laundry of the rotary wing single drive type only when the necessity is high. Thereby, the washing process and the rinsing process are difficult to unnecessarily extend.

而且，根据本实施方式，通过使用了借助于传动带和带轮的减速机构的简单结构，实现了采取双轴驱动方式、单轴驱动方式以及旋转翼单体驱动方式这三种驱动方式的驱动部30，因此，与使用了借助于齿轮的减速机构的情况相比，在故障等方面，能提高驱动部30的可靠性。Moreover, according to the present embodiment, by using a simple structure of a speed reduction mechanism by means of a belt and a pulley, a driving unit that adopts three driving modes of a two-axis driving method, a single-axis driving method, and a single-rotor driving method is realized. Therefore, the reliability of the drive unit 30 can be improved in terms of malfunction or the like as compared with the case where the speed reduction mechanism by means of the gear is used.

以上，对本发明的实施方式进行了说明，但本发明不受上述实施方式等的任何限制，另外，本发明的实施方式也可以进行上述以外的各种变更。Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and various modifications other than the above may be made in the embodiments of the present invention.

<变更例1><Modification 1>

在上述实施方式中，通过驱动电流检测部810来监视驱动电流值，由此，在施加于驱动电机100的负荷超过规定的大小的情况下进行旋转翼单体驱动方式的洗涤物的解开。与此相对，在本变更例中，在洗涤过程或漂洗过程中，在洗涤动作或漂洗动作开始之后，定期地进行旋转翼单体驱动方式的洗涤物的解开。由于不监视驱动电流值，因此，在本变更例中，不设置驱动电流检测部810。In the above-described embodiment, the driving current detecting unit 810 monitors the driving current value, thereby releasing the laundry of the rotary wing unit driving method when the load applied to the driving motor 100 exceeds a predetermined size. On the other hand, in the present modification, in the washing process or the rinsing process, the washing of the rotary wing unit driving method is periodically performed after the washing operation or the rinsing operation is started. Since the drive current value is not monitored, in the present modification, the drive current detecting unit 810 is not provided.

图11是表示变更例1的洗涤过程以及漂洗过程中的控制部801的控制动作的流程图。在图11的流程图中，与图9的流程图相比，S104的处理被置换为S121的处理。FIG. 11 is a flowchart showing a control operation of the control unit 801 in the washing process and the rinsing process in the first modification. In the flowchart of FIG. 11, the processing of S104 is replaced with the processing of S121 as compared with the flowchart of FIG.

在本变更例中，洗涤动作或漂洗动作中，控制部801判断是否到了解开开始时间(S121)。具体而言，在从开始洗涤动作或漂洗动作经过了预定的一定时间(例如，5分钟)以及该一定时间的倍数的时间(例如，10分钟、15分钟等)时，控制部801判断为到了解开开始时间。在本变更例中，一定时间的输入以及一定时间的倍数的时间的输入成为契机输入。此外，一定时间以及一定时间的倍数的时间相当于本发明的规定时间。In the present modification, in the washing operation or the rinsing operation, the control unit 801 determines whether or not the opening start time is known (S121). Specifically, when a predetermined period of time (for example, 5 minutes) and a multiple of the predetermined time (for example, 10 minutes, 15 minutes, etc.) elapse from the start of the washing operation or the rinsing operation, the control unit 801 determines that it is Untie the start time. In the present modification, the input of a certain time and the input of a multiple of a certain time become an opportunity input. In addition, a certain time and a certain time The multiple of the time corresponds to the prescribed time of the present invention.

在到了解开开始时间的情况下(S121：是)，控制部801结束洗涤动作或漂洗动作，通过离合器机构部700将驱动部30的驱动方式从双轴驱动方式切换至旋转翼单体驱动方式(S106)。When the start time is known (S121: YES), the control unit 801 ends the washing operation or the rinsing operation, and the clutch mechanism unit 700 switches the driving method of the driving unit 30 from the two-axis driving method to the single-rotor driving method. (S106).

根据本变更例的结构，双轴驱动方式的洗涤动作或漂洗动作中，在适当的时机进行旋转翼单体驱动方式的解开动作，因此，即使产生互相缠绕的洗涤物集中在滚筒22的中央部这样的状态，也能消除这样的状态。According to the configuration of the present modification, in the washing operation or the rinsing operation of the biaxial drive system, the unwinding operation of the rotary wing unit driving method is performed at an appropriate timing, and therefore, even if the mutually entangled laundry is concentrated in the center of the drum 22 Such a state can also eliminate such a state.

而且，根据本变更例的结构，可以不设置驱动电流检测部810等用于检测施加于驱动电机100的负荷的检测部。Further, according to the configuration of the present modification, the detection unit for detecting the load applied to the drive motor 100 such as the drive current detecting unit 810 can be omitted.

<变更例2><Modification 2>

图12是表示变更例2的洗涤过程以及漂洗过程中的控制部801的控制动作的流程图。图13是示意性地表示变更例2的通过解开动作解开后的洗涤物通过分散动作分散至滚筒22的内周面侧的样子的图。需要说明的是，在图12的流程图中，与图9的流程图相比，在S108的处理与S109的处理之间追加了S131至S133的处理。FIG. 12 is a flowchart showing the control operation of the control unit 801 in the washing process and the rinsing process according to the second modification. FIG. 13 is a view schematically showing a state in which the laundry that has been unwrapped by the unwinding operation in the second modification is dispersed to the inner circumferential surface side of the drum 22 by the dispersing operation. In addition, in the flowchart of FIG. 12, the process of S131 to S133 is added between the process of S108 and the process of S109, compared with the flowchart of FIG.

本变更例中，当经过解开时间(S108：是)、旋转翼单体驱动方式的解开动作结束时，控制部801通过离合器机构部700将驱动部30的驱动方式从旋转翼单体驱动方式切换至单轴驱动方式(S131)。然后，作为分散动作，控制部801以如下转速使驱动电机100单向地旋转(S132)，即，滚筒22以及旋转翼24以作用于滚筒22内的洗涤物的离心力大于重力的转速、例如120rpm一体地进行旋转。如图13所示，通过解开动作被解开而相互分离这样的状态的洗涤物通过由分散动作产生的离心力被向外侧推开，分散至滚筒22的内周面侧。由此，会进一步消除洗涤物对旋转翼24的压迫，会进一步减轻施加于旋转翼24的负荷。In the present modification, when the unwinding time has elapsed (S108: YES) and the unwinding operation of the single-rotor driving method is completed, the control unit 801 drives the driving method of the driving unit 30 from the rotary wing unit by the clutch mechanism unit 700. The mode is switched to the single-axis drive mode (S131). Then, as a dispersing operation, the control unit 801 rotates the drive motor 100 unidirectionally at a rotation speed (S132), that is, the drum 22 and the rotary vane 24 have a centrifugal force acting on the laundry in the drum 22 greater than the rotational speed of gravity, for example, 120 rpm. Rotate integrally. As shown in FIG. 13 , the laundry in a state in which the disengagement operation is disengaged and separated from each other is pushed outward by the centrifugal force generated by the dispersing operation, and is dispersed to the inner peripheral surface side of the drum 22 . Thereby, the pressing of the rotating blade 24 by the laundry is further eliminated, and the load applied to the rotary blade 24 is further reduced.

当经过作为分散所需的时间预先设定的分散时间时(S133：是)，控制部801结束分散动作，通过离合器机构部700将驱动部30的驱动方式从单轴驱动方式切换至双轴驱动方式(S109)。然后，作为洗涤动作或漂洗动作，控制部801再次使驱动电机100交替进行正转或反转(S103)。When the dispersion time set in advance for the time required for the dispersion is passed (S133: YES), the control unit 801 ends the dispersion operation, and the clutch mechanism unit 700 switches the drive mode of the drive unit 30 from the single-axis drive mode to the two-axis drive. Mode (S109). Then, as the washing operation or the rinsing operation, the control unit 801 causes the drive motor 100 to alternately perform forward rotation or reverse rotation (S103).

根据本变更例的结构，会进一步减轻通过旋转翼24施加于驱动电机100的负荷，会进一步抑制驱动电机100的锁死。According to the configuration of the present modification, the application to the drive motor 100 by the rotary wing 24 is further alleviated. The load further suppresses the locking of the drive motor 100.

需要说明的是，本变更例的S104的处理也可以置换为变更例1的S121的处理。该情况下，在适当的时机定期地进行旋转翼单体驱动方式的解开动作和单轴驱动方式的分散动作。In addition, the process of S104 of this modification example may be replaced with the process of S121 of the modification example 1. In this case, the unwinding operation of the rotary wing unit drive method and the dispersing operation of the single-axis drive method are periodically performed at an appropriate timing.

<其它变更例><Other changes>

在上述实施方式中，通过驱动电流检测部810来检测流经驱动电机100的驱动电流，由此判断施加于驱动电机100的负荷的大小。然而，也可以通过其它方法来判断施加于驱动电机100的负荷的大小。例如，也可以检测驱动电机100的转速，根据该转速是否达到为了洗涤动作或漂洗动作而设定的转速，判断施加于驱动电机100的负荷的大小。此外，也可以根据驱动电机100的转速达到设定的转速的时间来判断施加于驱动电机100的负荷的大小。In the above embodiment, the drive current detecting unit 810 detects the drive current flowing through the drive motor 100, thereby determining the magnitude of the load applied to the drive motor 100. However, the magnitude of the load applied to the drive motor 100 can also be judged by other methods. For example, the number of revolutions of the drive motor 100 may be detected, and the magnitude of the load applied to the drive motor 100 may be determined based on whether the number of revolutions reaches the number of revolutions set for the washing operation or the rinsing operation. Further, the magnitude of the load applied to the drive motor 100 may be determined based on the time when the rotational speed of the drive motor 100 reaches the set rotational speed.

此外，在上述实施方式中，虽然使用借助于传动带和带轮的减速机构实现了采取双轴驱动方式、单轴驱动方式以及旋转翼单体驱动方式这三种驱动方式的驱动部30，但也可以使用借助于齿轮的减速机构来实现采取上述三种驱动方式的驱动部30。Further, in the above-described embodiment, the drive unit 30 that adopts the three-drive method of the two-axis drive method, the single-axis drive method, and the rotary wing single drive method is realized by using the speed reduction mechanism by the drive belt and the pulley, but also The drive unit 30 that adopts the above three driving modes can be realized using a speed reduction mechanism by means of a gear.

而且，在上述实施方式中，在洗涤过程和漂洗过程双方，进行旋转翼单体驱动方式的解开动作。然而，这样的解开动作也可以仅在洗涤过程或漂洗过程中的某一方进行。Further, in the above embodiment, the unwinding operation of the single rotor driving method is performed in both the washing process and the rinsing process. However, such an unwinding action can also be performed only in one of the washing process or the rinsing process.

而且，在上述实施方式中，滚筒22以相对于水平方向倾斜的倾斜轴为中心进行旋转。然而，滚筒式洗衣机1也可以采用滚筒22以水平轴为中心进行旋转这样的结构。Further, in the above embodiment, the drum 22 is rotated about the tilt axis that is inclined with respect to the horizontal direction. However, the drum type washing machine 1 may be configured such that the drum 22 rotates around the horizontal axis.

而且，虽然上述实施方式的滚筒式洗衣机1不具备烘干功能，但本发明也可以适用于具备烘干功能的滚筒式洗衣机、即滚筒式洗衣干衣机。Further, although the drum type washing machine 1 of the above embodiment does not have a drying function, the present invention is also applicable to a drum type washing machine having a drying function, that is, a drum type washing and drying machine.

此外，本发明的实施方式可以在权利要求书所示出的技术思想的范围内适当地进行各种变更。 Further, the embodiments of the present invention can be variously modified as appropriate within the scope of the technical idea of the claims.
