The present invention relates to a drum washing machine, and more particularly, to a door assembly structure and a method for assembling the machine to make the exterior of the washing machine beautiful by easily separating the glossy part and the matte part of the door.

The washing machine is mainly driven by the electric motor, and the washing, rinsing, and dehydration processes are carried out to remove the dirt on the clothes by using the action of detergent and water. Its components consist of a motor, a power unit, a machine that transfers energy to the laundry, a control unit to control the washing process, a water supply and drainage system, and a water supply and drainage system.

In addition, the washing machine is classified into a drum type, agitator type, and a pulsator type according to a washing method.

Stirring type is a method of washing by rotating the wing-shaped stirrer to the left and right in the center of the washing tank, whip winding method is to wash with water generated by rotating the disk-shaped pulsator. In the drum type, water and detergent and laundry are put inside the drum in which the plurality of protrusions are formed, and the washing machine is washed by the impact of falling and being lifted by the protrusions. This method has almost no damage to the laundry and has the advantage of using less water, and in recent years, its use is increasing.

1 is a perspective view showing the appearance of a typical drum washing machine.

Referring to FIG. 1, a general drum washing machine 10 includes a cabinet 11 forming an external shape, a door 20 provided at an approximately center portion of the front part of the cabinet 11, and an upper side of the front part of the washing machine 10. It is formed in the detergent container 12 is injected into the detergent for washing, and a control unit 13 for controlling the operation of the washing machine 10 is included.

In detail, the door 20 has a door frame 21 having a circular shape, a deco band 22 formed at a front edge of the door frame 21, and an inner side of the deco band 22. A door glass 23 is recessed and protrudes into the washing machine.

In addition, the door glass 23 is recessed into the washing machine, and is made of a transparent material so that the laundry inside the drum is rotated so that the state of the laundry can be directly observed.

In the drum washing machine 10 having the above configuration, the user fills the detergent in the detergent container 12, injects laundry into the drum, and then adjusts the power button and the washing level provided in the controller 13. The washing is started by operating the.

On the lower side, when the washing is finished, the process proceeds to a drying step, and when the laundry is dried, the drum accommodated in the washing machine 100 is stopped. When the drum stops rotating, the door 20 is opened to take out the laundry.

In the case of the door structure having the above configuration, the door frame and the decor band is generally formed integrally. Therefore, in most cases, the door frame and the decor band are integrally glossy or integrally matt. Therefore, it is not easy to distinguish the decor band from the door frame of the glossy part, and it is difficult to produce a contrast effect between the glossy part and the semi-mineral part. In addition, since the contrast effect of the gloss portion and the semi-gloss portion is insufficient as described above, there is a disadvantage that the aesthetic appearance outside the theta is lowered.

The present invention has been proposed to solve the above problems, by improving the assembly structure of the door frame and the deco band, to provide a door assembly structure and assembly method of the washing machine that can increase the contrast effect of the glossy and semi-mineral portion. It aims to do it.

In addition, an object of the present invention is to provide a door assembly structure and a method of assembling a washing machine, which further facilitates a work process for forming a gloss portion and a semi-glossy portion by improving the assembly structure of the door frame and the decor band.

The door assembly structure of the drum washing machine according to the present invention for achieving the above object is an upper cover that is curved with a predetermined curvature from the outer periphery to the inner periphery, protruding a center boss of a predetermined length on the back; A center cover coupled to a lower side of the upper cover and including a seating groove for seating the center boss; It includes; a lower cover coupled to the lower side of the center cover.
In another aspect, a door assembly structure of a drum washing machine according to the present invention includes an upper cover curved at a predetermined curvature from an outer circumference to an inner circumference; A center cover coupled to a lower side of the upper cover and including a band-shaped prefastening rib extending a predetermined length from a bottom to a lower side, and an undercut surrounding an outer circumferential surface of the prefastening rib; A lower cover is provided below the center cover and includes a strip-shaped prefastening rib extending from an upper side to a predetermined height and an undercut surrounding the inner circumferential surface of the prefastening rib.

In addition, the door assembly method of the drum washing machine according to the present invention for achieving the above object comprises the step of combining the center cover by the center boss formed on the bottom of the upper cover; Inserting a door glass below the inner circumferential surface of the upper cover; The lower cover is coupled to the lower side of the center cover; Includes.

By the configuration as described above, there is an effect that the appearance of the washing machine is more beautiful by distinguishing the gloss of the front portion and the side portion of the door frame.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the spirit of the present invention is not limited to the embodiments presented, and other embodiments included within the scope of other inventive inventions or the scope of the present invention can be easily made by adding, changing, or deleting other elements. I can suggest.
