With reference to FIGS. 7 and 8 , the shape of the cover door (Y) according to an embodiment of the present disclosure will be described.

The door assembly (X) may include a cover door (Y).

The cover door (Y) may have a substantially circular shape.

In particular, as shown in FIG. 7, when the cover door (Y) is viewed from the front, the outside of the cover door (Y) may have a circular shape.

However, since tolerances may occur in the process of producing the cover door (Y), it may be difficult to say that the actual cover door (Y) has a perfect circular shape.

The shape of a circle or ellipse defined by the outside of the cover door (Y) may have an ellipse tolerance. The ellipse tolerance below can be said to be the difference or ratio between the shortest and longest distances when measuring the distance between two points that meet a circle or ellipse based on a line passing through the center of the circle or ellipse.

The cover door body 200 may have a circular cross-section. Oval tolerance can be less than 0.5%. It may be desirable for the elliptical tolerance to be 0.26% or less.

When forming the film layer 300 using the heat transfer method described later, it was confirmed that wrinkles appear in the film layer 300 if the elliptical tolerance is 0.25% or more.

In particular, it was experimentally confirmed that when the current size is 599.34 mm and the elliptical deviation is 3 mm or more, wrinkles appear when forming the film layer 300 by the heat transfer method.

If the elliptical tolerance of the cover door (Y) is 0.5% or less, it is possible to prevent wrinkles from forming in the film layer 300.

The cover door (Y) may include a film layer 300. The film layer 300 may be configured to cover at least a portion of the exterior of the cover door (Y).

Since the cover door (Y) may include a plastic material, it may be damaged by external impact. To prevent this, the cover door (Y) may include a film layer 300. Additionally, the user may have a higher aesthetic sense with respect to a metal material than with a plastic material. Since the cover door Y of the washing machine 1 is a component that defines part of the exterior of the washing machine 1, it may be necessary to create a high aesthetic feeling. This is because a high sense of aesthetics leads to purchases. Film layer 300 may include a metal layer 723 (FIG. 13) and thus may have a metallic color. If the film layer 300 is located on the cover door body 200, the user does not recognize the cover door (Y) as the material of the cover door body 200, but as a material of metal provided by the film layer 300.

The handle groove 212H may be configured to extend along the circumferential direction of the cover door (Y).

FIG. 10 is a cross-sectional view showing a cross-section of the cover door (Y) shown in FIG. 7. FIG. 11 is an enlarged view of the film attachment portion 210 of the cover door (Y) shown in FIG. 10. FIG. 12 is an enlarged view of the film attachment portion 210 of the cover door (Y) shown in FIG. 11.

With reference to FIGS. 10 to 12 , a cover door (Y) according to an embodiment of the present disclosure will be described.

The door assembly (X) may include a cover door (Y).

The cover door Y may include a seating portion 220 positioned to correspond to the shield member 100 and a film attachment portion 210 positioned outside the shield member 100. The film attachment portion 210 may be provided to extend from the seating portion 220.

The film attachment portion 210 may include an inclined portion. The inclined portion may be configured to facilitate the heat transfer method using the roller 900.

The inclined portion may be configured to have an inclined surface.

The inclined portion may include a decoration portion 211 provided adjacent to the shield member 100.

The inclined portion may include a cover portion 212 extending from the decoration portion 211 toward the rear of the door assembly (X).

The film attachment portion 210 may include a decoration portion 211 located on the radial outer side of the shield member 100 so that at least a portion of the edge of the shield member 100 is protected.

Explain in more detail.

The axis provided in the vertical direction based on the door assembly (X) can be referred to as the z-axis. The axis provided in the front-back direction may be referred to as the x-axis. The axis provided in the left and right directions can be called the y-axis.

In this case, the zy plane may be a configuration related to the deco portion 211. The zy plane can be called the deco plane.

The plane along which the shield member 100 extends may be parallel to the deco plane.

The deco portion 211 may have a deco inclined surface 211A located on the outside. A film layer 300 may be positioned on the deco inclined surface 211A.

When the deco part 211 is formed by pressing the film layer 300 on the deco part 211 by the roller 900, the deco part 211 has a deco inclined surface 211A that is inclined to prevent the film layer 300 from being folded. You can have it.

The deco inclined surface 211A may extend at an angle with the deco plane. The deco inclined surface 211A may be configured to be inclined with respect to the deco plane. The deco inclined surface 211A may be configured to be inclined with the deco plane.

As will be described later, the film layer 300 may be formed as the film 700 is attached to the cover door body 200. The film 700 may be attached to the cover door body 200 while the roller 900 rotates along the cover door body 200. If the deco inclined surface 211A is not inclined, the roller 900 cannot rotate and move along the deco inclined surface 211A. In this case, the roller 900 may need to press the film 700 through a linear motion so that the deco inclined surface 211A and the film 700 are compressed. If the roller 900 is not large enough, the roller 900 may require several reciprocating movements to attach the film 700 to the decoration portion 211.

When the deco inclined surface 211A has an inclination, the roller 900 is moved in the circumferential direction of the cover door (Y) while pressing the film 700 or the deco inclined surface 211A with which the film 700 is in contact. You can. Since the roller 900 can be moved in the circumferential direction of the cover door (Y) along the deco inclined surface 211A, the film 700 can be attached to the deco part 211 with only a small movement of the roller 900. there is.

The angle formed between the deco inclined surface 211A and the deco plane can be referred to as the deco angle. If the deco angle is not set appropriately, wrinkles may appear in the film layer 300.

Through experimentation, we looked for an appropriate decor angle. When the diameter of the cover door (Y) was 600 mm, wrinkles were formed in the film layer 300 when the deco angle was less than 10 degrees. Therefore, it is desirable that the deco angle has an angle of 10 degrees or more to prevent wrinkles from forming in the film layer 300.

The deco inclined surface 211A may have an angle of 10° or more with the vertical direction.

The deco angle may be less than 1/60 (degrees/mm) relative to the diameter (mm) of the cover door (Y).

The film layer 300 provided on the decoration portion 211 may be referred to as a decoration film layer 310. That is, the film layer 300 may include a decor film layer 310.

The xy plane can be called the cover plane.

The cover portion 212 may have a cover inclined surface 212A located on the outside. Film layer 300 may be positioned on cover inclined surface 212A.

The cover inclined surface 212A may extend at an angle with the cover plane. The cover inclined surface 212A may be configured to be inclined with respect to the cover plane. The cover inclined surface 212A may be configured to be inclined with the cover plane.

The cover door (Y) may be formed by an injection method. The injection-type production method may include putting the injection-molded product into a mold, forming it, and then separating it from the mold. When separating the injection product from the mold, the injection product needs an inclined surface so that it can be separated from the mold. If the mold has a vertically accommodated configuration, the extruded product may be difficult to separate from the mold.

Since the cover portion 212 of the cover door body 200 is provided on the outside of the cover door (Y), it may need to have an inclination so that it can be easily separated from the mold.

If the cover inclined surface 212A has an inclination, the cover door body 200 can easily be removed from the mold.

Through experimentation, we looked for an appropriate cover angle. When the diameter of the cover door (Y) was 600 mm and the cover angle was 3 degrees or more, the cover door body 200 was easily separated from the mold. Therefore, it may be desirable for the cover inclined surface 212A to be configured to have an angle of 3 degrees or more with the cover plane.

The cover angle can be 1/200 (degree/mm) or more with respect to the diameter (mm) of the cover door (Y).

However, if the cover angle is too large, it may be difficult to attach the film at once, or wrinkles may appear in the film layer 300.

This is because the cover inclined surface 212A is inclined, so the diameter of the edge located at the rear is larger than the diameter of the edge located at the front. Accordingly, the film 700 extending along this may not be able to cover as much as the difference in circumference due to the difference in diameter as it moves from the front edge of the cover inclined surface 212A toward the rear edge.

Additionally, if the cover angle is too steep, wrinkles may appear in the film 700.

Through experiments, we looked for an appropriate cover angle that would not cause wrinkles in the film 700. When the diameter of the cover door (Y) was 600 mm and the cover angle exceeded 6 degrees, wrinkles were formed in the film layer 300. Therefore, the cover angle is preferably less than 6 degrees to prevent wrinkles from forming in the film layer 300.

The cover angle may be less than 1/100 (degrees/mm) relative to the diameter (mm) of the cover door (Y).

In summary, it is desirable for the cover angle to be between 3 degrees and less than 6 degrees. Alternatively, the cover angle is preferably 1/200 (degree/mm) or more and less than 1/100 (degree/mm) with respect to the diameter (mm) of the cover door (Y).

The cover inclined surface 212A may have a direction perpendicular to the vertical direction and an inclination of 3° or more.

When the cover inclined surface 212A is formed by pressing the film layer 300 on the cover inclined surface 212A by the roller 900, the cover inclined surface 212A may have an inclination of 6° or less to prevent the roller 900 from being separated. there is.

The film layer 300 provided on the cover portion 212 may be referred to as a decor film layer 310. That is, the film layer 300 may include a decor film layer 310.

FIG. 13 is an enlarged cross-sectional view of the film 700 attached to the cover door body 200 shown in FIG. 7.

With reference to FIG. 13, a film 700 according to an embodiment of the present disclosure will be described.

The cover inclined surface 212A-2 may be configured to be parallel to the cover plane. The cover inclined surface 212A-2 may be configured to be parallel to the xy plane.

The cover inclined surface 212A-2 may require a predetermined cover angle for injection. However, when the cover door body 200-2 is not formed using injection, the cover inclined surface 212A-2 may not require a cover angle. Alternatively, even if injection is used, if a process that does not require an angle for injection is used, a cover angle may not be needed.

When the cover angle is 0 degrees, it may be easy for the film layer 300 to be formed on the cover inclined surface 212A-2. This is because there is no difference in the circumference of the circle provided on the front side of the cover portion 212 and the circumference of the circle provided on the rear side, so the film 700-2 can be easily wound.

A film layer 300-2 may be positioned on the cover portion 212-2. A cover film layer 320-2 may be positioned on the cover portion 212-2. A cover film layer 320-2 may be positioned on the cover inclined surface 212A. The film layer 300-2 may be configured to correspond to the cover inclined surface 212A-2.

The deco inclined surface 211A-3 may require a deco angle so that the roller 900 can rotate and move along the deco inclined surface 211A-3. However, if a configuration other than the roller 900 can perform the heat transfer process by pressing the deco inclined surface 211A-3, the deco inclined surface 211A-3 may not require a deco angle. Alternatively, even if the roller 900 is used, if there is another configuration that guides the movement of the roller 900, the deco angle may not be necessary.

When there is a deco angle, the difference between the circumference of the circle provided on the front side of the deco part 211-3 and the circumference of the circle provided on the rear side of the deco part 211-3 is the same as when there is a cover angle. Therefore, when the deco angle is 0 degrees, it may be easy for the film layer 300-3 to be formed on the deco inclined surface 211A-3.

The film layer 300-3 may be positioned on the decoration portion 211-3. The decor film layer 310-3 may be positioned on the decor portion 211-3. The deco film layer 310-3 may be positioned on the deco inclined surface 211A-3. The film layer 300-3 may be configured to correspond to the deco inclined surface 211A-3.
