FIG. 2 is a front view showing the state in which the door 12 is viewed from the front in FIG. 1, and FIG. 3 is an exploded view showing the state in which the door 12 of FIG. 2 is disassembled.

The door 12 may be composed of a door frame 13, a door window 23, a windshield 20, a hinge unit 24 and a locking unit 30.

The door frame 13 may be formed in a ring shape.

The door frame 13 may be composed of an outer frame 14 (outer frame) and an inner frame 19 (inner frame). The outer frame 14 and the inner frame 19 may be formed of synthetic resin material (eg, ABS material, PC material, etc.).

When each of the outer frame 14 and the inner frame 19 is made of a synthetic resin material, it may be manufactured by injection molding.

Each of the outer frame 14 and the inner frame 19 is formed in a ring shape, and can be fastened by being arranged in an overlapping direction in the front-to-back direction. The fastening structure between the outer frame 14 and the inner frame 19 will be described in detail later.

When explaining the reasons for naming the outer frame 14 and the inner frame 19, the outer frame 14 and the inner frame 19 are based on the state in which the door 12 is closed, and the outer frame 14 is the main body 10 It faces the outside of, and the inner frame 19 is named as being disposed towards the inside of the main body 10. The outer frame 14 may be referred to as a first frame, and the inner frame 19 may be referred to as a second frame.

A circular opening 18 is formed inside each of the outer frame 14 and the inner frame 19 to correspond to each other.

The opening 18 may be eccentrically positioned at the center of each of the outer frame 14 and the inner frame 19. For example, the center of the opening 18 may be located above the center of each of the outer frame 14 and the inner frame 19.

According to this configuration, each of the outer frame 14 and the inner frame 19 may have a different width along the circumferential direction. That is, the distance (width) between the outer diameter and the inner diameter (the diameter of the opening 18) of each of the outer frame 14 and the inner frame 19 may be configured to increase (widen) from the top to the bottom.

The center of the drum may be disposed higher than the center of height (1/2) of the main body 10.

The drum is fixed in the height direction of the main body 10 apart from the minute vibration caused by rotation.

Consumers tend to prefer that the size of the door 12 is large compared to the same capacity and size of the washing machine when looking at the body 10 from the front.

In addition, consumers can look into the interior of the drum through the door 12 and, if possible, prefer to secure a wide field of view of the interior space of the drum.

In order to satisfy the needs of the above-mentioned consumers, in order to increase the size of the door 12 while the position of the drum is fixed, the door 12 must be enlarged downward.

The center of the door frame 13 should be moved downward than the center of the clothing inlet 102 or the opening 18. Similarly, the door frame 13 may be centered downward with respect to the door window 23 positioned corresponding to the opening 18.

In addition, in order to increase the size of the door 12, it is preferable that a part of the door 12 protrudes outward from the recess 103. The diameter of the door 12 is preferably formed larger than the recess portion 103.

The windshield 20 is formed in a circular shape with a predetermined radius. The windshield 20 is formed of a glass material.

The windshield 20 has a flat front and rear surfaces.

The windshield 20 is formed in a disc shape having a constant thickness, and is formed without bending even when viewed from up, down, left, or right.

As described above, the front windshield 20 made of a glass material is formed in a circular shape and the front and rear surfaces are flat, so that the quality of the door 12 is higher than that of the existing door cover made of synthetic resin material in which the front is convexly formed in an incomplete circular shape. Improves.

A transmissive alignment mark 221 is formed in the non-transmissive region 22. The alignment mark 221 is configured to guide the attachment position of the windshield 20 to the outer frame 14. In this figure, a circular alignment mark 221 is formed on the lower side of the windshield 20 (at 6 o'clock). However, the present invention is not limited to this. The alignment mark 221 may be formed in a polygonal shape or may be formed in a line shape. Of course, the position of the alignment mark 221 may be changed.

The front glass 20 may implement the light-transmissive region 21, the non-transmissive region 22, and the alignment mark 221 through the following layer structure.

For example, the front glass 20 may include a glass body formed of a light-transmitting glass material, and a shielding layer disposed to cover the rear surface of the glass body to form an opaque region 22. At this time, the portion where the shielding layer is not disposed forms the light-transmitting region 21 and the alignment mark 221. The shielding layer may be formed by initial printing on the rear surface of the glass body.

As another example, the front glass 20 may include a glass body formed of a light-transmissive glass material, and a film disposed to cover the rear surface of the glass body. The film has a light-transmitting portion formed to have light-transmitting properties corresponding to the light-transmitting region 21, a light-transmitting portion formed to have light-transmitting properties corresponding to the non-light-transmitting region 22, and light-transmitting properties corresponding to an alignment mark 221. It may include an alignment portion formed.

As another example, the front glass 20 may include a glass body formed of a light-transmissive glass material and a film disposed to cover the rear surface of the glass body. Here, the difference from the above example is, the first hole in which the film is formed to correspond to the transmissive region 21, the opaque portion formed to have opacity in response to the translucent region 22, and the alignment mark ( The second hole is formed to correspond to 221). That is, there is a difference in whether the portion corresponding to the light-transmitting region 21 and the alignment mark 221 in the film is formed to have light-transmitting properties or has a perforated shape.

The windshield 20 may be arranged to cover the opening 18 of the door frame 13. The windshield 20 may be adhered to the front surface of the outer frame 14 by a sealant or adhesive.

Due to the nature of the glass material, it is easy to break when a fastening hole is drilled in the windshield 20, so the windshield 20 is attached to the outer frame 14 using an adhesive or the like to prevent the glass from breaking.

On the other hand, the windshield 20 is a glass material and occupies a relatively large load compared to the total load of the door 12. In order to support the load of the windshield 20, a mounting guide 34 for mounting the windshield 20 is provided on the front of the outer frame 14.

In particular, the windshield 20 may be made of tempered glass. Due to the characteristics of the tempered glass, the front and rear surfaces of the windshield 20 have strong strength, but the circular outer peripheral surface, which is the side surface of the windshield 20, has a weak strength.

In order to compensate for this, the mounting guide 34 is formed to protrude forward from the front outer circumferential end of the outer frame 14 so as to surround the outer circumferential surface of the windshield 20, as well as support the load of the windshield 20, The side of the windshield 20 can be protected from external impact.

The protruding length of the mounting guide 34 may be formed to cover at least 2/3 of the thickness of the windshield 20.

This is because, when the protruding length of the mounting guide 34 is too short, external impact may be applied to the outer circumferential surface of the windshield 20, and the load of the windshield 20 cannot be sufficiently supported.

For example, a straight portion 202 and a plurality of curved portions 201 and 203 may be formed on the outer circumferential surface of the windshield 20 (see FIG. 7 ). The plurality of curved portions 201 and 203 may include a first curved portion 201 connected to the front surface of the windshield 20 and a second curved portion 203 connected to the rear surface of the windshield 20. have. Each of the plurality of curved portions 201 and 203 has a constant curvature and is formed in a curved shape.

The straight portion 202 is disposed between the first and second curved portions 201 and 203 and connected to the plurality of curved portions 201 and 203, respectively. Each of the first curved portion 201, the straight portion 202, and the second curved portion 203 may be 1/3 of the thickness of the windshield 20.

The mounting guide 34 may be configured to cover the second curved portion 203 and the straight portion 202 of the windshield 20.

The mounting guide 34 may protrude from the front edge of the outer frame 14. The mounting guide 34 extends in a ring shape to form a space in which the windshield 20 is accommodated.

The mounting guide 34 has a preset inner diameter and forms a circular shape. The inner diameter of the mounting guide 34 corresponds to the outer diameter of the windshield 20, so that the mounting guide 34 surrounds the outer circumferential surface of the windshield 20.

The mounting guide 34 may be formed to protrude to a constant thickness to form the same plane as the front surface of the windshield 20. According to this configuration, a simpler appearance can be realized by eliminating the step between the mounting guide 34 and the windshield 20.

The transmissive region 21 and the non-transmissive region 22 may be formed inside and outside the windshield 20, respectively.

The light-transmitting area 21 is configured to transmit at least a portion of light, and means an area formed to be visible from the opposite side to the inside. Accordingly, the light-transmitting region 21 is a concept including the semi-light-transmitting region 21.
