The first arm 62 may be fixed to the drum 3 by a bolt fastened to the first fastening groove 623 by passing through the first through hole 355, the second arm 63 may be fixed to the drum 3 by a bolt fastened to the second fastening groove 633 by passing through the second through hole 356, and the third arm 64 may be fixed to the drum 3 by a bolt fastened to the third fastening groove 643 by passing through the third through hole 357.

As shown in FIG. 3A, in order to reinforce strength of the connector C, a strength reinforcing unit 65 may further be provided on a surface in the space provided by the connector, wherein the surface is in contact with the second surface 35.

The strength reinforcing unit 65 may be provided in such a manner that a plurality of boards cross one another to form a lattice structure. However, if the strength reinforcing unit 65 is provided in such a lattice structure, particles from laundry or detergent may remain in the space formed between the respective boards.

In some embodiments, the strength reinforcing unit 65 may be provided in a shape shown in FIG. 3B. That is, as shown in FIG. 3B, the strength reinforcing unit 65 may comprise a first arm rib 621 provided along a longitudinal direction (Z-axis direction) of the first arm 62, a second arm rib 631 provided along a longitudinal direction of the second arm 63, and a third arm rib 641 provided along a longitudinal direction of the third arm 64.

The first arm rib 621 may comprise a plurality of boards spaced apart from one another along a width direction (Y) of the first arm 62, the second arm rib 631 may comprise a plurality of boards spaced apart from one another along a width direction of the second arm 63, and the third arm rib 641 may comprise a plurality of boards spaced apart from one another along a width direction of the third arm 64. Since the respective boards of the connector C according to this embodiment are provided along the longitudinal direction of each arm even though particles and the like enter the space between the respective boards, the particles and the like may be discharged to the outside of the connector C while the drum is being rotated.

FIG. 4 illustrates another example of the connector C. The connector C according to this embodiment comprises a structure in which particles and the like may be washed by the water stored in the tub 2 when the drum 3 is rotated.

That is, the connector C according to this embodiment comprises a first body 71 fixed to the second surface 35 (e.g., rear surface) of the drum, a second body 73 to which the rotary shaft S is fixed, and a connecting portion 74 configured to connect the first body 71 with the second body 73. The connecting portion 74 may be configured to form a path through which water passes to a space between the first body 71 and the second body 73 as well as maintain the state in which the first body 71 is spaced apart from the second body 73.

The first body 71 may comprise a first body hub 711 fixed to the second surface 35 and located in the center of rotation of the drum 3, and first body arms 713, 714 and 715 extending from the first body hub 711 toward the rim of the second surface 35.

The second body 73 may comprise a second body hub 731 disposed inside the tub 2, to which the rotary shaft 2 is fixed, and second body arms 733, 734 and 735 extending from the second body hub 731 toward the same direction as the direction, in which the first body arms are extended. The second body hub 731 may be provided in the same shape as that of the first body hub 711 and thus may be parallel to the first body hub 711.

The first body arm may be only comprise a first body first arm 713 extending from the first body hub 711 toward the rim of the second surface 35, and the second body arm may only comprise a second body first arm 733 extending from the second body hub 731 along the direction in which the first body first arm 713 is extended from the first body hub 711.

In this case, the connecting portion 74 may comprise a first connecting body 741 provided to be downwardly inclined from one end (left end of the first body first arm in FIG. 4) of both ends of the first body first arm 713 toward the rotary shaft S, and a second connecting body 743 provided to be downwardly inclined from the other end (right end of the first body first arm in FIG. 4) of both ends of the first body first arm 713 toward the rotary shaft S.

One end of each of the first connecting body 741 and the second connecting body 743 may be fixed to the first body first arm 713, and the other end of each of the first connecting body 741 and the second connecting body 743 may be provided with a board connected to the second body first arm 733.

However, one end of the first connecting body 741 and one end of the second connecting body 743 may be provided so as not to be connected with each other, or may be provided to be connected with each other at a connecting point 745. FIG. 4 illustrates that the two connecting bodies 741 and 743 are configured to meet each other at the connecting point 745, as an example. In any case, the connecting portion 74 may have a V shape pointed toward the rotary shaft S.

If the connecting portion 74 comprises a V-shape pointed toward the rotary shaft S, the connector C may support all of a force acting on a width direction (Y-axis direction) of the first body first arm 713, a force acting on a longitudinal direction (Z-axis direction) of the first body first arm 713, and a force acting on a thickness direction (X-axis direction) of the connector. Therefore, the present disclosure may provide a connector C that may not only stably transfers the rotation power provided by the motor to the drum and but also has high strength.

Although not shown, the connecting portion 74 may comprise a V-shape pointed toward a direction away from the rotary shaft S. That is, the connecting portion 74 may include a first connecting body 741 upwardly inclined from a left end of the first body first arm 713 toward the direction away from the rotary shaft S, and a second connecting body 743 provided to be upwardly inclined from a right end of the first body first arm 713 toward the direction away from the rotary shaft S.

Meanwhile, as shown in FIG. 5, the connecting portion 74 may comprise a board shaped connecting body parallel to the width direction (Y-axis direction, that is, direction orthogonal to the direction headed for the free end of the first body first arm from the rotary shaft) of the first body first arm 713.

Moreover, the connecting portion 74 may be disposed along the width direction Y of the first body first arm 713, and may be comprise a board shaped connecting body bent toward a direction (−Z-axis direction) in which the rotary shaft S is located or bent at a certain curvature toward a direction (+Z-axis direction) away from the rotary shaft S.

The connecting portion 74 of the aforementioned structure may comprise a plurality of connecting portions, each of which may be spaced apart from another one along the longitudinal direction (Z-axis direction, that is, direction toward the free end of the first body first arm from the rotary shaft) of the first body first arm 713. As such, a path 77, through which water moves between the respective connecting portions 7, may be formed.

In some embodiments, the first connecting body provided in one connecting portion and the first connecting body provided in another connecting portion are parallel to each other, and the second connecting body provided in one connecting portion and the second connecting body provided in another connecting portion are parallel to each other. As such, manufacturing convenience may be enhanced when the connector is manufactured using a mold.

The water stored in the tub during rotation of the drum (during rotation of the rotor or during rotation of the connector) may move along the path 77 formed by the connecting portion 74. Therefore, the present disclosure may not only minimize particles and the like discharged from laundry remaining in the connector C but also wash the particles remaining in the connector C.

Also, the connector C of the aforementioned structure may minimize a weight of the connector due to the path 77 formed by the connecting portion 74, whereby energy to be supplied to the motor may be minimized due to the weight of the connector (energy required for rotation of the drum is minimized).

As shown in FIG. 6, the connector C may further comprise rib 78 connecting the connecting point 745 provided in one connecting portion to the connecting point 745 provided in another connecting portion, thereby enhancing the strength of the connector.
