In order to achieve the fifth object described above, in the mounting guide, an inner surface surrounding the windshield may be formed parallel to an outer circumferential surface of the windshield in a thickness direction of the windshield.

The effects of the laundry treatment apparatus according to the present invention will be described as follows.

First, the mounting guide protrudes from the outer periphery of the outer frame to surround the outer periphery of the windshield, and the mounting guide is formed to cover a portion of the outer periphery (straight part and inner curved part) of the windshield, thereby reducing the size of the mounting guide while reducing the size of the front Glass can be supported.

If the mounting guide covers the entire thickness of the outer circumferential surface of the windshield, the length of the mounting guide protruding in the thickness direction of the windshield becomes longer. should be formed to increase the thickness of

For example, when the windshield has a first curved portion (outer curved portion), a straight portion, and a second curved portion (inner curved portion) in the thickness direction from the outside to the inside, the mounting guide is the outer circumferential surface of the windshield. It may be configured to cover the straight part of the. The length in which the mounting guide protrudes in the thickness direction of the windshield is configured to cover 2/3 of the outer circumferential surface of the windshield. According to this configuration, the size of the mounting guide can be reduced while securing the supporting force of the windshield.

Second, the mounting guide protrudes from the outer periphery of the windshield to surround the outer periphery of the windshield, preventing the adhesive formed on the inner side of the outer frame from leaking to the outside of the outer frame, as well as preventing moisture from penetrating into the inner side of the outer frame. can be prevented

Third, the outer periphery of the outer frame protrudes from the front surface of the outer frame so as to surround the windshield to form a mounting guide, and the inner surface of the mounting guide is formed parallel to the side surface of the windshield in the thickness direction of the windshield. Even if the adhesive force between the front surfaces of the outer frame is weakened, sufficient support force of the outer frame with respect to the windshield can be secured.

Second, as the thickness of the mounting guide increases from a point on the front or side of the windshield toward the rear of the windshield, the rigidity of the mounting guide that can withstand the weight of the windshield can be secured by itself.

Third, a structure such as a reinforcing rib is formed to protrude from the rear surface of the outer frame so as to overlap the adhesive filling groove in the thickness direction of the outer frame, so that it is possible to structurally reinforce the weakening of the rigidity of the outer frame due to the adhesive filling groove.

Fourth, since the outer frame and the inner frame are coupled to each other by a hook fastening structure, the coupling force between the outer frame and the inner frame can be improved without drilling a fastening hole in the windshield.

Second, each of the first hook of the outer frame and the second hook of the inner frame has a wedge-shaped hook protrusion, and each hook protrusion has a second inclined surface in contact with each other after the first hook and the second hook are fastened. It is formed to be steeper than the inclination of the first inclined surfaces in contact with each other, so it is easy for the second hook to enter the inside of the first hook, but it is possible to restrict the second hook from being separated from the first hook.

Third, by forming an elastic groove on the rear surface of the outer frame, the first hook of the outer frame and the second hook of the inner frame are fastened to each other to induce the first hook to be deformable in the radial direction, so that the second hook is Since it is possible to easily enter the inside of the first hook, it is possible to improve assembly between the outer frame and the inner frame.

Fourth, the compression unit has a plurality of compression ribs, connection ribs and support ribs on the rear surface of the outer frame, and the compression ribs compress the second hook when the first hook of the outer frame and the second hook of the inner frame are connected to each other. Even though the weight of the windshield occupies a relatively large proportion to the total weight of the door, it prevents the second hook from being deformed radially inwardly or in the gravitational direction with respect to the first hook, and the fastening force between the first and second hooks is reduced. You can keep it more robust.

Fifth, the connecting ribs protrude to connect the plurality of compression ribs to the rear surface of the outer frame, and are formed in a ring shape along the circumferential direction, so that the support strength of the outer frame with respect to the windshield and the compression force of the plurality of compression ribs can be strengthened. .

Sixth, the plurality of support ribs are formed to protrude from the rear surface of the outer frame and integrally connected to the inner circumferential surface of the connection ribs, thereby further strengthening the supporting force for the connection ribs and the compression ribs.

Seventh, the mounting guide protrudes from the outer periphery of the outer frame to surround the outer circumferential surface of the windshield toward the front of the door, and a gap is formed between the inner circumferential surface of the mounting guide and the outer circumferential surface of the windshield. It is possible to prevent the breakage of the outer peripheral surface of the windshield and to protect the side surface of the windshield from external impact.

Since the rear panel and the left and right side panels are formed by bending a single rectangular plate in a "C" shape, structural rigidity of the main body 10 can be improved.

The clothes inlet 102 may be formed in a circular shape on the front panel 101 (refer to FIG. 5 ). The clothes inlet 102 is formed to penetrate through the front panel 101 , so that clothes can be put into the clothes accommodating part through the clothes inlet 106 .

The clothes inlet 102 may be formed to be recessed toward the inside of the main body 10 so that the recess 103 in the front panel 101 surrounds the clothes inlet 102 . The clothes inlet 102 is formed to pass through the inside of the recess 103 . A portion of the door 12 may be accommodated in the recess 103 .

The door 12 may be rotatably coupled to the front panel 101 by a hinge 25 to open and close the clothing inlet 102 .

A clothing accommodating part may be provided inside the main body 10 . The clothes accommodating unit may include a drum to perform a drying function, or a tub and a drum to perform both washing and drying functions.

In this embodiment, in order to perform a drying function together with washing, a tub and a drum may be provided inside the main body 10 . The tub may be formed in a cylindrical shape, and a central axis of the tub in the longitudinal direction may be horizontal or inclined at a predetermined angle. Washing water can be stored inside the tub.

The drum may be rotatably provided inside the tub.

A gasket is installed at the front end of the tub in communication with the clothes inlet 102 to prevent the washing water stored in the tub from leaking into the receiving space of the main body 10 .

The drum may be rotatably installed in the tub with respect to the tub.

The front part of the drum is open and connected to the clothes inlet 102 in communication with it, and clothes can be accommodated in the drum through the clothes inlet 102 .

A driving motor is installed on the rear surface of the tub, and the driving motor is connected to a rotating shaft on the rear surface of the drum.

A plurality of through-holes are formed on the circumferential surface of the drum, so that a fluid such as washing water can enter and exit the drum through the plurality of through-holes.

The drum may be configured to have a plurality of lifters therein to rotate the clothes accommodated in the drum to perform washing and drying functions.

The control unit 11 may be provided in the main body 10 or may be provided in the door 12 . In this embodiment, the control unit 11 is shown to be positioned above the front panel 101 of the main body 10 .

The control unit 11 is configured to display information related to an administration process processed by the laundry treatment apparatus to a user and receive a user's manipulation. The control unit 11 may include a circular knob and a plurality of buttons for receiving a user's manipulation. Also, the control unit 11 may include a display unit for displaying visual information.

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

The door 12 may include 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 include an outer frame 14 and an inner frame 19 . The outer frame 14 and the inner frame 19 may be formed of a 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 may be overlapped and fastened to each other in the front and rear directions. A fastening structure between the outer frame 14 and the inner frame 19 will be described in detail later.

When explaining the reason for naming the outer frame 14 and the inner frame 19, the outer frame 14 and the inner frame 19 are the body 10 based on the state in which the door 12 is closed. It faces the outside of, and the inner frame 19 is named as being disposed toward 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.

Circular openings 18 are formed inside each of the outer frame 14 and the inner frame 19 to correspond to each other.

The opening 18 may be located eccentrically from 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, it may be configured such that the distance (width) between the outer and inner diameters (diameter of the opening 18) of each of the outer frame 14 and the inner frame 19 increases (widens) from the uppermost end to the lowermost end.

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

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

Consumers tend to prefer a larger door 12 compared to the same capacity and size of the washing machine when the main body 10 is viewed from the front.

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

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

The center of the door frame 13 should be moved lower than the center of the clothes inlet 102 or the opening 18 . Similarly, the door frame 13 may be centrally moved downward with respect to the door window 23 positioned to correspond 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 protrude outward from the recess 103 . Preferably, the door 12 has a larger diameter than the recess 103 .

The windshield 20 is formed in a circle having a predetermined radius. The windshield 20 is formed of a glass material.

The front glass 20 has a flat front and a rear surface.

The windshield 20 is formed in the form of a disk having a constant thickness, and is formed without bending when viewed from anywhere up, down, left, and right.

As such, the glass windshield 20 is formed in a circular shape with flat front and back surfaces, so that the luxury of the door 12 is improved compared to the conventional door cover made of synthetic resin, which has a convex front in an incomplete circular shape. is improved

A transmissive alignment mark 221 is formed in the non-transmissive area 22 . The alignment mark 221 is a configuration for guiding 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 (6 o'clock) of the windshield 20 . However, the present invention is not limited thereto. 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 windshield 20 may implement the transmissive area 21 , the non-transmissive area 22 , and the alignment mark 221 through the following layer structure.

For example, the windshield 20 may include a glass body formed of a light-transmitting glass material, and a shielding layer disposed to cover a rear surface of the glass body to form a non-transmissive region 22 . In this case, the portion where the shielding layer is not disposed forms the light-transmitting area 21 and the alignment mark 221 . The shielding layer may be formed by vitreous printing on the back surface of the glass body.

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

As another example, the windshield 20 may include a glass body formed of a light-transmitting glass material, and a film disposed to cover the rear surface of the glass body. Here, the difference from the above example is that the film has a first hole formed to correspond to the transmissive area 21 , a non-transmissive portion formed to have opacity corresponding to the non-transmissive area 22 , and an alignment mark ( 221) in that it includes a second hole formed to correspond to it. That is, there is a difference in whether portions of the film corresponding to the light-transmitting area 21 and the alignment mark 221 are formed to have light-transmitting properties or have a perforated shape.

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

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

Meanwhile, the windshield 20 is made of glass 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 surface of the outer frame 14 .

The mounting guide 34 serves the following three functions.

First, the mounting guide 34 may protect the windshield 20 from external impact.

Second, the mounting guide 34 may support the windshield 20 .

Third, it is possible to guide the position of the windshield 20 when assembling the windshield 20 . The main role of the mounting guide 34 is to protect the windshield 20 .

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

To compensate for this, the mounting guide 34 is formed to protrude forward from the outer peripheral end of the outer frame 14 so as to surround the outer peripheral surface of the windshield 20, so as to protect the side surface of the windshield 20 from external impact. have.

9 is a front view showing a state in which the windshield 20 is mounted on the inside of the mounting guide 34 according to the present invention. FIG. 10 is a cross-sectional view taken along line X-X in FIG. 9 .

The outer frame 14 may be made of a plastic material. The outer frame 14 may be manufactured by plastic injection molding. For example, the outer frame 14 may be formed by chromium plating (or painting) on the ABS injection molding. The mounting guide 34 may be integrally formed on the outer periphery of the outer frame 14 .

The windshield 20 may be mounted inside the mounting guide 34 . A gap (G) may be formed between the inner circumferential surface of the mounting guide 34 and the outer circumferential surface of the windshield 20 .

The gap G between the mounting guide 34 and the windshield 20 is an allowance for preventing the outer peripheral surface of the windshield 20 from breaking (tempered glass self-breaking phenomenon) due to the plastic injection molding deformation of the outer frame 14 . it is space

Since plastic and glass have different degrees of deformation due to heat due to the characteristics of the material, the outer peripheral surface of the windshield 20 may be broken due to deformation of the plastic injection product.

The gap G between the mounting guide 34 and the windshield 20 may be in the range of 0.1 mm to 1.0 mm.

If the gap G is smaller than 0.1 mm, the windshield 20 may be cracked due to deformation of the plastic injection molded product.

If the gap (G) is greater than 1.0 mm, when the door is viewed from the front, the gap (G) may be seen or a problem in which a foreign material is caught in the gap (G) may occur. In addition, if the gap G is too large, the windshield 20 may be tilted toward one side from the inner center of the mounting guide 34 .

In addition, the mounting guide 34 wraps the outer circumferential surface of the windshield 20 to support the load of the windshield 20 .

Preferably, the gap G between the mounting guide 34 and the windshield 20 is preferably within the range of 0.5 mm to 0.7 mm. The reason is to manage the size of the gap within 1 mm because one side may be larger than 1 mm when the front glass 20 is tilted.

When the door is viewed from the front, the mounting guide 34 may be formed in a ring shape. The smaller the width (W) of the mounting guide 34 compared to the diameter of the door 12, the better. This is because the diameter of the windshield 20 can be increased as the width W of the mounting guide 34 is smaller compared to the same size of the door. The mounting guide 34 may be 3.5% of the diameter of the door.

The width (W) of the mounting guide 34 is an outer circumferential diameter (D1; Outer Diameter) and an inner circumferential diameter (D2: Inner Diameter) of the mounting guide 34 along a radial center line passing in a radial direction through the center of the outer frame 14 ) means half the difference. That is, the width W=(D2-D1)/2 of the mounting guide 34 .

The width W of the mounting guide 34 may be uniformly formed in the circumferential direction.

The width W of the mounting guide 34 may be 1.5 mm to 6.0 mm.

The width W1 of the mounting guide 34 is preferably at least 1.5 mm or more in consideration of the thickness (3.2 mm) of the windshield 20 . If the width W1 of the mounting guide 34 is too small, the mold resolution is not managed and molding is impossible.

Here, the minimum value of the width W1 of the mounting guide 34 means the width W1 of a portion formed in a plane on the upper portion of the mounting guide 34 in the cross-sectional view of FIG. 10 .

The width W2 of the mounting guide 34 is preferably 6.0 mm at most. If the width W2 of the mounting guide 34 is too large, a problem of shrinkage occurs during plastic molding, making it difficult to accurately manage the dimensions of the mounting guide 34 .

In addition. If the width of the mounting guide is too large, there is a problem that the appearance is not beautiful.

Here, the maximum value of the width W2 of the mounting guide 34 is the horizontal distance between the outer circumferential surface of the hook 37 provided under the mounting guide 34 in the cross-sectional view of FIG. 10 and the inner circumferential surface of the mounting guide 34 . means (distance).

The mounting guide 34 may include an inner peripheral surface portion 345 , a front surface portion 342 , a round portion 343 , and an inclined surface portion 344 , and may form the outermost portion of the outer frame 14 .

The inner peripheral surface portion 345 is formed to protrude more toward the front of the door than the front surface of the outer frame 14 . The front surface of the outer frame 14 may include a flat portion 15 to which the rear surface of the windshield 20 is attached.

The inner circumferential portion 345 is formed in a ring shape along the circumferential direction to surround the outer circumferential surface of the windshield 20 .

An elastic groove 38 is formed on the back surface of the flat portion 15 of the outer frame 14 in the thickness direction, so that when the first hook 46 is inserted into the second hook 47, the first hook ( 46) can be elastically deformed radially outward by the elastic groove (38).

In addition, the second hook 36 can easily enter the inside of the first hook 37 by the chamfers 461 and 471 .

In addition, the first hook 37 and the second hook 36 can be prevented from being separated from each other by the contact portions 462 and 472 .

A reinforcing rib 45 from one side of the handle 35 may protrude toward the second adhesive overflow groove 442 .

The reinforcing rib 42 may be disposed to contact the opposite side of the second adhesive overflow groove 442 . The reinforcing rib 45 of the handle 35 can compensate for the weakening of the strength of the flat portion 15 due to the thinness of the flat portion 15 due to the second adhesive overflow groove 442 .

In addition, the reinforcing rib 42 serves as a spacer for maintaining a constant distance between the handle 35 and the flat portion 15 , thereby making it possible to reduce the thickness of the handle 35 .

In addition, the reinforcing rib 42 can not only reinforce the strength of the handle 35 even when the thickness of the handle 35 is reduced, but also the contact portion 462 of the first hook 46 and the second hook 47 . of the contact portions 472 may maintain a state of mutual contact.

Therefore, by the fastening structure of the first hook 46 of the outer frame 14 and the second hook 47 of the handle 35, the coupling and assembly properties between the outer frame 14 and the inner frame 19 can be improved. can
