The access hole 36 serves as a passage through which the foreign matter collecting device 46, which will be described below, can flow in and out of the washing machine.

The entrance hole 36 is provided with an entrance hole 38. The entrance hole 38 serves to selectively shield the entrance hole 36.

On the other hand, the tub 40 is provided inside the cabinet 30. The tub opening 42 is formed on the front surface of the tub 40 so as to correspond to the inlet 32 of the cabinet 30. In addition, the tub 40 is integrally formed with the cabinet 30. That is, the front surface of the tub 40 is coupled to the inner wall of the cabinet 30 so that the cabinet 30 and the tub 40 are integrally formed.

In addition, the rear surface of the tub 40 is shielded to form a predetermined space therein. The tub 40 serves to store the wash water in the predetermined space. One side of the tub 40 is supported by the shock absorber 44 inside the cabinet 30.

In addition, a foreign matter collecting device 46 is provided at an inner lower end of the tub opening 42 which is an inner side of the entrance hole 36. The foreign matter collecting device 46 prevents foreign matter from entering the space between the tub 40 and the drum 50 to be described below, and also serves to collect foreign matter.

The foreign matter collecting device 46 is provided with a storage container 48. One side of the storage container portion 48 is opened to form a predetermined space therein, and serves to substantially store the foreign matter.

The foreign matter collecting device 46 is provided with a container accommodating part 49. The container accommodating part 49 allows the cabinet 30 and the tub 40 to be in contact with each other so that a predetermined space is formed. The container accommodating part 49 is a place where the storage container part 48 is stably fixed inside the washing machine.

In addition, a hook member 48a may be provided at one side, and a hook groove 49a may be provided at the other side so that the storage container 48 may be detachably attached to the container accommodating part 49. In this embodiment, the hook member 48a is formed in the storage container portion 48, and the hook groove portion 49a is formed in the container accommodation portion 49, and the hook member 48a is formed in the container accommodation portion. A hook groove 49a may be formed in the storage container 48 at the 49.

In addition to the hook member 48a and the hook groove 49a, any structure can be applied as long as the storage container 48 can be stably fixed to the container housing 49 at the level of those skilled in the art.

The drum 50 is rotatably installed in the tub 40. The drum 50 is formed in a cylindrical shape and is provided with a drum opening 52 corresponding to the front opening 32 and the tub opening 42. Laundry can be introduced into the drum 50 through the drum opening 52.

In addition, a plurality of through holes (not shown) are formed in the body of the drum 50. The through hole serves to allow the wash water and the dry air to flow into and out of the drum 50 during washing.

The rear side of the tub 40 is provided with a motor portion 54 for rotating the drum (50). A driving shaft 56 is provided at the rotation center of the motor unit 54, and the driving shaft 56 is connected to the drum 50 through the tub 40. Therefore, the rotational force of the motor unit 54 is transmitted to the drum 50 along the drive shaft 56 so that the drum 50 can rotate.

A balance 58 is provided at the front of the drum 50, more specifically at the edge of the drum opening 52. The balance 58 is formed around the edge of the drum opening 52 in a ring shape, and the inside of the balance 58 is hollow to form a tube.

Liquid is injected into the hollow space of the balance 58. The liquid is injected into the hollow space, so that the eccentricity, which is about to be caused by the deflection of laundry and washing water, when the drum 50 rotates, is compensated by the movement of the liquid.

In addition, as shown in FIG. 2, the balance 58 is formed such that a plurality of hollow rings are sequentially stacked. Preferably it may be formed of a quadruple ring. The front surface of the balance 58 is formed to be inclined, and the outer width may be formed to be smaller than the inner width from the center of the drum 50.

The upper end of the balance 58 is provided with a guide 60 extending in the tub opening 42 direction. The guide 60 is preferably formed to be inclined in the direction of the foreign matter collecting device 46. The guide 60 serves to guide the foreign matter flowing in the drum 50 to be stably moved to the storage container 48 of the foreign matter collecting device 46.

Hereinafter, the operation of the drum washing machine according to the present invention having the configuration as described above will be described in detail.

First, the user inserts laundry into the drum 50, closes the door 34, and inputs an operation signal to a controller (not shown) of the washing machine. When the washing machine starts to operate, the washing water is introduced into the tub 40 through a water supply pipe (not shown).

In addition, while the washing water flows through the detergent container (not shown), the amount of detergent input to the controller of the washing machine is introduced into the drum 50 together with the washing water. The laundry in the drum 50 is prepared by washing water introduced into the tub 40 to complete the washing.

When the inflow of the wash water is completed, the controller instructs the motor unit 54 to rotate by applying power, and the rotational force of the motor unit 54 is transmitted to the drum 50 along the drive shaft 56. To rotate the drum 50.

Washing proceeds while the drum 50 rotates, and the washing process includes a washing process in which laundry is washed, a rinsing process for rinsing the laundry, a dehydration process for removing the wash water from the laundry, and washing water in the laundry. It consists of a drying process that removes completely.

In each process, the drum 50 rotates at a high speed. At this time, foreign matter introduced into the drum 50 such as laundry moves to the front of the drum 50 by the rotation of the drum 50. Done.

The foreign matter that has moved forward of the drum 50 is first restricted by the balance 58 protruding in the direction of the center of rotation of the drum 50. And, even though the balance 58 passes, the foreign matter is introduced into the storage container portion 48 of the foreign matter collecting device 46 by the guide 60 installed in the balance 58.

In addition, when the drum 50 is completely stopped, the user opens the access door 38 and removes the storage container part 48 from the container accommodating part 49 to the outside of the washing machine.

The foreign substance is removed from the storage container part 48 removed to the outside of the washing machine, and the storage container part 48 is seated in the container accommodating part 49 through the access hole 36.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

For example, in the present invention, the foreign matter collecting device 46 is provided at the front lower end of the tub 40, but the foreign matter collecting device 46 is provided at the front lower end of the cabinet 30, that is, the inlet 32. It may be provided at the bottom edge.

Drum washing machine according to the present invention as described in detail above has the following effects.

The foreign matter collecting device is provided between the drum and the tub to prevent foreign matter from entering between the drum and the tub, and at the same time, there is an effect of collecting the foreign matter.

In addition, the foreign matter is prevented from flowing between the drum and the tub, the noise generated by the operation of the drum and the tub is prevented, and the durability is increased.
