A drain motor for driving the drain pump is embedded in the drain pump housing 24.

The drainage assembly 20 may be disposed between the outer tub 4 and the base 5.

3 is a perspective view illustrating a state in which a lint filter is detached from a tub cover of a washing machine according to a first embodiment of the present invention, FIG. 4 is a perspective view of the lint filter shown in FIG. 3, and FIG. 5 is shown in FIG. 3. The bottom surface of the top cover is shown in plan view.

3 to 5, the tub cover 14 is equipped with a lint filter 50 for filtering foreign substances such as seams contained in the wash water.

When the inner tub 6 rotates at a high speed, the wash water is discharged to the outside of the inner tub 6 through the through hole of the inner tub 6 by centrifugal force, and then the inner tub 6 and the outer tub 6 (4) flows to the tub cover 14 side along the space between, and after hitting the tub cover 14 is introduced into the interior of the inner tub (6) (hereinafter referred to as 'alpha stream'. ).

The lint filter 50 is provided on the rear surface of the tub cover 14 that is the flow path of the alpha stream. When the alpha stream is formed, foreign matter may be filtered while washing water passes through the lint filter 50.

The lint filter 50 may be disposed in the circumferential direction on the rear surface of the tub cover 14, or may be disposed over the entire rear surface of the tub cover 14. In the present embodiment, it is described that the plurality of lint filters 50 are arranged to be spaced apart from the rear surface of the tub cover 14 by a predetermined interval. As an example, as shown in FIG. 5, three lint filters 50 may be disposed.

The lint filter 50 is detachably coupled to the tub cover 14 to facilitate cleaning. In other words, the lint filter 50 may be detachably attached to the tub cover 14. In addition, the tub cover 14 may be slid in a radial direction.

That is, the user can easily take out the lint filter 50 by pulling the lint filter 50 in the radial direction of the tub cover 14 and pushing the lint filter 50 to the lower side of the tub cover 14.

A guide rail 14a for guiding the slide movement of the lint filter 50 is formed on the rear surface of the tub cover 14. The guide rail 14a protrudes downward from the rear surface of the tub cover 14.

A guide rib 54 protrudes from the lint filter 50 so as to be caught by the guide rail 14a. The guide rib 54 may be mounted on the guide rail 14a and slide along the guide rail 14a. The guide ribs 54 protrude from the left and right side surface portions 51b and 51c of the lint filter 54, respectively.

The lint filter 50 includes a filter box 51 having a drawer shape having an upper surface and a rear surface thereof, and a mesh portion 52 provided on the lower surface of the filter box 51 to filter foreign substances from the wash water. do.

The rear surface of the filter box 51 is formed to be opened so that the washing water rising along the space between the outer tub 4 and the inner tub 6 can be introduced into the inside. However, the present invention is not limited thereto, and the rear surface of the filter box 51 may be shielded and a separate inflow hole may be formed.

The mesh unit 52 forms a lower surface of the filter box 51.

In the filter box 51, the handle portion 53 is formed at the front portion 51a facing the center of the tub cover 14 so as to be grasped by a user. The handle portion 53 is a recess recessed toward the rear of the filter box 51.

Looking at the action of the lint filter according to an embodiment of the present invention configured as described above are as follows.

When the washing machine is turned on and the motor 8 is driven, the inner tub 6 is rotated.

When the inner tub 6 is rotated at a high speed higher than a predetermined rotation speed, the washing water flows out of the inner tub 6 through the through hole of the inner tub 6 by centrifugal force. The drained wash water rises toward the tub cover 14 along the space between the inner tub 6 and the outer tub 4, and is then reintroduced into the inner tub 6.

At this time, the washing water rising toward the tub cover 14 passes through the lint filter 50.

The washing water raised toward the tub cover 14 flows into the open rear surface of the lint filter 50, and foreign matter in the washing water is filtered while passing through the mesh part 52.

As described above, when the inner tub 6 rotates at a high speed to form an alpha stream, the lint filter 50 is disposed in the flow path of the alpha stream, thereby filtering out foreign substances in the wash water using the alpha stream. have.

When foreign matter accumulates in the lint filter 50, after the operation of the washing machine is finished, the user may detach the lint filter 50 by pulling the handle 53 of the lint filter 50.

By detaching the lint filter 50, the foreign matter in the lint filter 50 can be washed off or shaken off. Since the attachment and detachment of the lint filter 50 is easy, the use and management of the lint filter 50 are easy.

6 is an exploded perspective view illustrating a lint filter according to a second embodiment of the present invention.

Referring to FIG. 6, the lint filter 60 according to the second embodiment of the present invention has a structure and an operation other than the mesh portion 64 detachably coupled from the filter box 62, according to the present invention. Since the same as the first embodiment of the present invention can be implemented similarly, the description of the overlapping with the first embodiment of the present invention can be omitted.

That is, the lint filter 60 is a filter box 62 which is detachably coupled to the tub cover 14, and a mesh unit which is detachably coupled to the filter box 62 and filters foreign substances of washing water ( 64).

A lower opening hole 62b is formed in a lower surface of the filter box 60, and the mesh part 64 is placed on the lower opening hole 62b.

In addition, a front opening hole 62a may be formed in the front portion of the filter box 60, and the mesh portion 64 may be inserted and removed through the front opening hole 62a.

In addition, it may be possible to replace only the mesh unit 64 as a separate consumable at regular intervals.

Those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is indicated by the scope of the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalent concept are included in the scope of the present invention. Should be interpreted.

According to the present invention, a lint filter is disposed below the tub cover, which is on the upper side of the alpha flow path, by using a principle of forming an alpha stream flowing upward through the side wall of the inner tub by centrifugal force when the inner tub rotates. By mounting, the wash water can filter out the foreign matter more effectively. In addition, since the lint filter is mounted in a drawer type and detachable, it is easy to clean and the usability can be improved.
