Description

Door assembly and refrigerator including same {Door assembly and refrigerator having this}

The present invention relates to a door assembly and a refrigerator including the same, and more particularly, to a door assembly capable of varying the length of an outer cover of a door, and a refrigerator including the same.

BACKGROUND ART In general, a refrigerator is a home appliance that can store food at a low temperature in an internal storage space that is shielded by a door. To this end, the refrigerator is configured to store the stored food in an optimal state by cooling the inside of the storage space using cold air generated through heat exchange with the refrigerant circulating in the refrigeration cycle.

Recently, refrigerators are becoming increasingly multifunctional according to changes in dietary habits and the trend of luxury products, and various devices are being added to increase user convenience. In addition, as the capacity of the storage room is gradually increasing, large refrigerators are being made.

For example, a touch panel is placed on the front of the refrigerator door so that the user can input a signal through the touch panel, or an automatic opening device is installed at the top or bottom of the door to automatically open the door when the user approaches the door. You can also make it open. Korean Patent Application Laid-Open No. 10-2020-0015846 discloses a door opening device installed on the upper surface of a door, and Korean Patent Laid-Open Patent No. 10-2018-0067391 discloses a structure in which a display is installed on the door.

Since these door devices require power supply, they are electrically connected to the main body (cabinet) side of the refrigerator. Electrical connection is made with a wire harness, which is housed in Cap Deco, the frame of the door, and Cap Deco cover is coupled to Cap Deco to shield parts such as wire harnesses and hinges.

However, since door housing parts such as Cap Deco or Cap Deco cover must be designed and produced differently depending on the size and shape of the refrigerator, productivity and economic efficiency are deteriorated. In recent refrigerators, even when the capacity of the storage compartment is the same, the size of the entire or part of the refrigerator may be minutely changed depending on conditions such as an installation form or a housing structure, making it more difficult to share the housing parts.

For example, a free-standing type refrigerator and a built-in type refrigerator need to have a different outer shape to match the installation environment, and a customer-customized refrigerator needs to be placed on the outside of the refrigerator. Since housing parts of the material and color selected by the buyer are additionally installed, the length of the exterior also changes, and the door housing parts also change accordingly.

In addition, the door housing parts have a narrow width and a long length due to the characteristics of the door shape, so that the entire length may deviate from the allowable error while being warped or contracted during the injection molding process. In this case, there is a problem in that parts cannot be used or the exterior surface of the door does not form a continuous plane, which reduces the aesthetics.

SUMMARY OF THE INVENTION The present invention is to solve the problems of the prior art as described above, and an object of the present invention is to make it possible to use a cover for covering a door frame even if the housing shape or thickness of the door assembly is different.

Another object of the present invention is to compensate for this by adjusting the overall length of the cover even if the length of the housing parts constituting the door frame is out of tolerance.

According to a feature of the present invention for achieving the above object, a frame cover for covering a door frame is assembled in the present invention, and as the main cover and the hinge cover constituting the frame cover move away from or close to each other, the overall length of the frame cover may be variable. Accordingly, even if the shape and size of the door assembly are different, the frame cover can be shared.

In addition, the main cover and the hinge cover constituting the frame cover can adjust the overall length of the frame cover while moving relative to each other, and can match the length of the door frame. Even if the housing parts of the door assembly including the door frame deviate from the tolerance during the manufacturing process, it is possible to compensate for this by adjusting the length of the frame cover within a certain range.

According to the present invention, the door frame constitutes at least a part of the outer periphery of the door, and a storage space is formed therein. An edge of the door frame has a hinge mounting portion to which a hinge is mounted. The frame cover may be coupled to the door frame to shield the storage space, and form a part of a surface of the door together with the door frame. The frame cover includes a main cover extending along the longitudinal direction of the door frame, and a hinge cover for adjusting the overall length of the frame cover through relative movement with the main cover.

In addition, the main cover has a first assembly part at an assembly position with the hinge cover, and the hinge cover has a second assembly part coupled to the first assembly part and movable relative to the first assembly part. Separation of the main cover and the hinge cover can be prevented before the main cover is assembled to the door frame through the assembly of the first assembly part and the second assembly part.

In addition, in a state in which the main cover and the hinge cover are spaced apart from each other in the door frame, a spacer may fill a space formed between the main cover and the hinge cover. The spacer may prevent flow between the main cover and the hinge cover.

In this case, the spacer is provided at a position corresponding to between the main cover and the hinge cover, and the spacer protrudes in a direction in which the frame cover is coupled to the door frame. Accordingly, in the process of assembling the frame cover to the door frame, it may be naturally inserted between the main cover and the hinge cover.

In addition, the first assembly part of the main cover and the second assembly part of the hinge cover may be assembled to each other in the same direction as the frame cover is assembled to the door frame. In this way, assembling direction is unified into one, and assembling property is improved.

In addition, when the main cover and the hinge cover are assembled with each other, a portion of the surface of the main cover and a portion of the surface of the hinge cover are in surface contact with each other to form a contact surface. In addition, the contact surface may be formed in a flat or curved surface along a direction in which the hinge cover moves relative to the main cover. This contact surface increases the contact area between the main cover and the hinge cover to enable stable adhesion, and may prevent sliding of each other during the assembly process.

A guide hole penetrating through the assembly direction of the main cover and the hinge cover is formed in the first assembly part, and the guide hole extends along a direction in which the main cover and the hinge cover move relative to each other. In addition, the second assembly part is provided with a guide hook that is inserted into the guide hole and moves inside the guide hole. Accordingly, the guide hook may move along a predetermined path in the guide hole.

At this time, when the guide hook is inserted into the guide hole, the engaging jaw of the guide hook is caught and fixed to the edge of the guide hole. The locking jaw may protrude in a direction orthogonal to the assembly direction of the main cover and the hinge cover to maintain a firmly hooked state.

In addition, the first assembly part has a plate-shaped assembly plate that protrudes in a direction perpendicular to the assembly direction of the main cover and the hinge cover, and the second assembly part has a pressing plate that is laminated with the assembly plate to make surface contact. do. Accordingly, the main cover and the hinge cover maintain a surface contact state in the vertical direction, thereby reducing the play of the assembly part.

In addition, when the main cover and the hinge cover are assembled with each other, the first assembly part and the second assembly part of the main cover are in surface contact with each other, and the first assembly part and the second assembly part are the main cover and the hinge They overlap each other in the assembly direction of the cover. Accordingly, the first assembly unit may press the second assembly unit downward toward the door frame, and play of the hinge cover may be prevented.

A guide hole is formed in the first assembly portion of the main cover, and the guide hole has a plurality of first length adjustment ends along a relative movement direction of the main cover and the hinge cover. In addition, the second assembly portion of the hinge cover has a guide hook fitted into the guide hole, and the guide hook has a second length adjusting end engaged with the first length adjusting end. Through this structure, the hinge cover can be moved in stages.

In addition, the first length adjustment end has a concave-convex shape continuously formed along the relative movement direction of the main cover and the hinge cover on the inner surface of the guide hole, and the second length adjustment end is the first length adjustment end on the surface of the guide hook. It protrudes in a direction opposite to the first length adjustment end and engages with at least one of the plurality of first length adjustment ends. In addition, the second length adjusting end may have a concave-convex shape continuously formed along the longitudinal direction of the first length adjusting end.

In addition, a pressing plate on which the first assembly part is seated is provided at a position adjacent to the guide hook of the second assembly part, and when the guide hook is caught on the edge of the guide hole of the first assembly part, the pressing plate is at least a part of the first assembly part can be interviewed with

In addition, a cover stopper protrudes from the hinge cover, and the cover stopper contacts the main cover while the hinge cover moves relative to the main cover. Accordingly, the cover stopper may limit the movement of the hinge cover.

In addition, the cover stopper protrudes in a direction parallel to the relative movement direction of the main cover and the hinge cover, and the main cover is provided with a stopper engaging end to interfere with the cover stopper to limit the movement of the hinge cover. The stopper engaging end may support at least a portion of the cover stopper, and may increase the fixing force of the hinge cover.

In addition, there is a pressing plate pressed in the direction of the door frame by the assembly plate of the first assembly part on one side of the hinge cover, and the cover stopper protrudes from the opposite side of the pressing plate with respect to the guide hook and the stopper of the main cover It can be supported on the locking end. In this way, both ends of the hinge cover can be stably supported by the main cover.

In addition, a position fixing part protrudes from a lower portion of the hinge cover, and the position fixing part is caught on an edge of the hinge mounting part to prevent the hinge cover from protruding outward of the door frame.

In addition, a harness guide having a curved outer surface protrudes from the upper surface of the first assembly part. In addition, an inclined surface may be formed on a side surface of the first assembly part in a direction to narrow a width of the first assembly part. Both the harness guide and the inclined surface may prevent damage to the wire harness.

In addition, a plurality of cantilever-shaped fastening hooks protrude from the main cover around the edge of the main cover toward the door frame, and the fastening hooks may be fixed by being caught on the fastening jaws of the door frame.

As discussed above, the door assembly according to the present invention and the refrigerator including the same have the following effects.

In the door assembly of the present invention, a frame cover (cap deco cover) that covers the frame (cap deco) of the door is assembled, and as the main cover and the hinge cover constituting the frame cover move away from or close to each other, the overall length of the frame cover may vary. can Since the length of the frame cover can be adjusted in this way, even if the shape and size of the door assembly are different, the frame cover can be shared, and the productivity and economic efficiency of the door assembly are improved.

In particular, even when the capacity of home appliances such as refrigerators is the same, but the installation shape or thickness of the housing is slightly changed, the frame cover constituting the door assembly of the present invention can be applied through length adjustment. Accordingly, the design freedom of the home appliance including the door assembly can be made more flexible, and the degree of freedom in design can be improved, and compatibility can be improved because it can be applied to various types of housings.

In addition, since the door frame of home appliances such as refrigerators has a narrow width and a long length, there is a fear that it is twisted or contracted during the injection molding process and deviate from an tolerance. can If the length of the frame cover is adjusted to the length of the door assembly in this way, the outer surfaces of the door frame and the frame cover can form a continuous plane, thereby increasing the aesthetics of the home appliance.

In addition, through the concavo-convex shape in the assembly portion of the main cover and the hinge cover constituting the frame cover, the length of the frame cover can be adjusted in stages. By adjusting the length of the frame cover step by step, the frame cover can be assembled on door frames of various lengths, and accordingly, it is possible to respond to housings of various thicknesses assembled on the outside of the door.

In addition, the main cover is assembled and fixed to the door frame, and the main cover and the hinge cover have sections overlapping each other in the assembly direction. Therefore, the hinge cover located between the main cover and the door frame is pressed toward the door frame by the overlapping amount of the main cover, and the hinge cover pressed toward the door frame can be firmly fixed in the vertical direction without play, thereby increasing assembly completion. there is

In addition, if the space between the main cover and the hinge cover is spaced apart to increase the length of the frame cover, the spacer of the door frame can fill the spaced space. When the spacer fills the space between the main cover and the hinge cover, the frame cover can be maintained in a solidly assembled state without any play, and the completeness of the product can be improved.

In particular, the spacer protrudes in a thin plate-like structure at the installation position of the frame cover, and in the process of assembling the frame cover to the door frame, the spacer naturally penetrates between the main cover and the hinge cover, thereby widening the gap between the main cover and the hinge cover. Therefore, the operator does not need to insert the spacer between the main cover and the hinge cover one by one or precisely adjust the distance between the main cover and the hinge cover in advance, thereby improving workability.

In addition, in the frame cover of the present invention, a harness guide having a curved surface is provided on the movement path of the wire harness. Accordingly, even if the wire harness is in contact with the frame cover, it is possible to prevent the wire harness from being damaged by the frame cover.

And, since the frame cover of the present invention is divided into a main cover and a hinge cover, the length of the parts is relatively short compared to that the entire frame cover is made of one part. Accordingly, the deformation rate of the component such as warpage can be reduced, and there is an effect that can lower the defective rate of the component.

In addition, (i) when the distance between the main cover and the hinge cover is narrowed to shorten the length of the frame cover, the main cover and the hinge cover are in continuous surface contact with each other along the longitudinal direction, (ii) to increase the length of the frame cover For this reason, even if the gap between the main cover and the hinge cover is widened, the spacer is filled in between them so that they are also in continuous surface contact with each other. Accordingly, the gap between the main cover and the hinge cover is minimized to improve aesthetics, and there is an effect of effectively preventing foreign substances from being introduced.

The frame cover 50 is composed of a main cover 60 and a hinge cover 70, as will be described below, before being assembled to the door frame 40 as shown in FIG. 6, the main cover 60. and the hinge cover 70 may be assembled to the door frame 40 in an assembled state.

Since the hinge cover 70 is assembled to either end of the main cover 60 constituting the frame cover 50, when the frame cover 50 is assembled to the door frame 40, the storage space 42 and one hinge mounting portion 45 may be shielded at the same time. The main cover 60 has a shape in which both left and right sides are symmetrical, and a hinge cover 70 may be assembled on either one of the left and right sides of the main cover 60 . That is, regardless of the position where the hinge is mounted, the main cover 60 is used in common, and only the hinge cover 70 is changed. In this embodiment, when viewed from the front of the door assembly 20, the hinge cover 70 is assembled to the right end of the main cover (60).

7 and 8, the cover body 61 of the main cover 60 has an approximately 'C'-shaped cross-section, and the inside is recessed to create an empty space. The front and rear surfaces of the cover body 61 have a wall structure protruding in the direction of the storage space 42, respectively, and an empty space is created therebetween. The inwardly recessed portion may be connected to the storage space 42 so as not to interfere with the wire harness stored in the storage space 42 .

However, both ends of the main cover 60 are not 'C'-shaped, but have a 'L'-shaped cross-section as shown in FIG. 9 , from which an assembly plate 65 to be described below protrudes. Accordingly, both ends of the main cover 60 are opened in the front, more precisely, in the front direction of the door. As such, it can be seen that the first assembly part 63 and the second assembly part 73, which will be described below, are assembled with each other through the part open to the front.

A fastening hook 62 protrudes from the main cover 60 . The fastening hook 62 protrudes from the main cover 60 toward the receiving space 42 in a cantilever shape, and is caught and fixed by the fastening jaw 43 on the inner surface of the receiving space 42 . When the fastening hook 62 is caught on the fastening jaw 43 , the main cover 60 may be fixed without being separated from the receiving space 42 . A plurality of fastening hooks 62 are provided around the edge of the main cover 60 , and correspond to the number and position of the fastening jaws 43 .

As shown in FIGS. 8 and 9 , the main cover 60 includes a first assembly part 63 . The first assembly part 63 is provided at both ends of the main cover 60 , respectively, and is assembled with the hinge cover 70 . The first assembly part 63 is not clearly distinguished from the cover body 61 of the main cover 60, and is responsible for assembly with the hinge cover 70 at both ends of the cover body 61. It can be seen as a generic name for the parts that do.

Referring to FIG. 9 , when the hinge cover 70 is assembled to the main cover 60 , the first assembly part 63 is positioned relatively forward than the second assembly part 73 of the hinge cover 70 . do. In addition, the body portion constituting the first assembly portion 63 includes (i) a vertical portion 61a extending in a direction in which the frame cover 50 is assembled to the door frame 40, and (ii) the vertical portion It is connected orthogonally at (61a) and includes a horizontal portion (61b) covering the upper surface of the storage space (42). And, the inner space of the vertical portion (61a) and the horizontal portion (61b) is opened to the front.

10 and 11 in which the main cover 60 and the hinge cover 70 are separated from each other, the first assembly part 63 of the main cover 60 is based on the longitudinal direction of the cover body 61 . It protrudes forward and there is an empty space behind it. The empty space at the back becomes a coupling space 63 ′, and the coupling space 63 ′ is filled by the second assembly 73 . At this time, the surface 63a of the first assembly portion 63 facing the second assembly portion 73 of the hinge cover 70 is orthogonal to the direction in which the main cover 60 and the hinge cover 70 are assembled with each other. It may consist of a continuous flat surface or a curved surface along one direction.

And, the surface 63a of the first assembly part 63 is in surface contact with the surface of the second vertical plate 71c to be described below among the surfaces of the hinge cover 70 . Accordingly, a portion of the surface 63a of the main cover 60 and a portion of the surface of the second vertical plate 71c of the hinge cover 70 are in surface contact with each other to form a contact surface P. And the contact surface P may be formed in a flat or curved surface along the direction in which the hinge cover 70 moves relative to the main cover 60 . In this case, the surface 63a of the first assembly part 63 is engaged with the surface of the second vertical plate 71c, and the main cover 60 and the hinge cover 70 are arbitrarily sliding in the left and right directions. can In this case, the surface 63a of the first assembly part 63 may be configured only with a curved surface or only with a flat surface.

The first assembly part 63 includes an assembly plate 65 . The assembly plate 65 protrudes from the vertical portion 61a in a direction perpendicular to the assembly direction of the main cover 60 and the hinge cover 70 . The assembly plate 65 has a thin plate shape, and a guide hole 66 is penetrated therein. A guide hook 75 of the second assembly part 73 to be described below is fitted into the guide hole 66 .

The assembly plate 65 extends along the longitudinal direction of the main cover 60, and may be parallel to the horizontal portion 61b. The assembly plate 65 does not extend to the end of the edge of the main cover 60, but is spaced apart from the stopper engaging end 69 to be described below. And the cover stopper 78 of the hinge cover 70 is located in the empty space where the assembly plate 65 and the stopper engaging end 69 are spaced apart from each other.

The guide hole 66 formed in the assembly plate 65 is made to pass through the assembly plate 65 , and the guide hook 75 of the hinge cover 70 is inserted into the guide hole 66 to be caught. In this case, the main cover 60 and the hinge cover 70 may be temporarily assembled with each other and cannot be separated. The guide hole 66 extends along a direction in which the main cover 60 and the hinge cover 70 move relative to each other, and the guide hook 75 is inserted into the guide hole 66 to fit the guide hole 66 . ) can be moved inside.

Referring to FIG. 16 , the guide hole 66 has an uneven shape. The concave-convex shape is a first length adjusting end 66a, and the first length adjusting end 66a is a relative movement direction of the main cover 60 and the hinge cover 70 on the inner surface of the guide hole 66. formed continuously along the That is, the first length adjusting end 66a has a continuous concave-convex structure, and the second length adjusting end 76a of the guide hook 75 to be described below engages here.

When the second length adjusting end 76a is engaged with the first length adjusting end 66a, the guide hook 75 may move step by step along the guide hole 66 . More specifically, it can be seen that the first length adjustment end 66a has a plurality of groove structures in succession, and the distance between the plurality of grooves becomes the moving distance of the first stage of the guide hook 75 .

Referring back to FIG. 10 , a harness guide 67 is provided on the assembly plate 65 of the first assembly part 63 . The harness guide 67 is formed in a curved shape on the upper surface of the assembly plate 65 . In this embodiment, the harness guide 67 has a substantially semicircular cross-section, and extends in the same direction as the direction in which the assembly plate 65 protrudes from the vertical portion 61a.

The harness guide 67 is to prevent the surface of the wire harness (not shown) passing the upper portion of the assembly plate 65 from being swept away by the assembly plate 65 from being damaged. Of course, since the harness guide 67 has a plurality of ribs, it can also serve to enhance durability by reinforcing the strength of the assembly plate 65 . As shown in FIG. 9 , the same shape as the harness guide 67 may be provided on the bottom surface of the horizontal portion 61b.

In addition, an inclined surface 67a is formed on the side surface of the building plate 65 constituting the first assembly part 63 in a direction to narrow the width of the assembly plate 65 . Like the harness guide 67 , the inclined surface 67a may also serve to prevent the surface of the wire harness passing through the upper portion of the assembly plate 65 from being swept away by the assembly plate 65 .

Meanwhile, the assembly plate 65 is laminated with the pressing plate 77 of the second assembly part 73 to be described below. 9, the assembly plate 65 is laminated on the upper surface of the pressing plate 77 of the second assembly part 73, and the assembly plate 65 pushes the pressing plate 77 downward, that is, the door frame ( 40) direction. In this case, the hinge cover 70 can be firmly fixed without flowing in the vertical direction. This structure will be described again below.

Referring to FIG. 11 , an assembly projection 68 is provided on the outer surface of the first assembly part 63 . The assembly jaw 68 is caught on the outer edge of the door frame 40 when the main cover 60 is assembled to the door frame 40 . The assembling jaw 68 is drawn outward from the side surface of the first assembly part 63 and may be provided at both ends of the main cover 60, respectively.

The first assembly part 63 has a stopper engaging end 69 . The stopper engaging end 69 protrudes inward from the vertical part 61a of the first assembly part 63 . The stopper engaging end 69 protrudes inward from the inner surface of the vertical portion 61a and is located at the lower end of the vertical portion 61a. Referring to FIG. 10 , the end of the stopper engaging end 69 may be seen to protrude toward the assembly plate 65 .

Referring to FIG. 12 , the cover stopper 78 of the second assembly part 73 is seated on the stopper engaging end 69 . More precisely, the cover stopper 78 interferes with the stopper engaging end 69 during the movement of the hinge cover 70 . In this case, the hinge cover 70 can no longer protrude outward, and movement is restricted.

In this embodiment, the stopper engaging end 69 supports the cover stopper 78 from below. In addition, it can be seen that the stopper engaging end 69 in the first assembly part 63 is provided at a position farthest from the assembly plate 65 . Accordingly, at one end, the assembly plate 65 presses the pressing plate 77 from top to bottom, and at the opposite end, the stopper engaging end 69 supports the cover stopper 78 from the bottom to the top. Conversely, it can be seen that the cover stopper 78 supports the stopper engaging end 69 from above. In this way, the first assembly part 63 and the second assembly part 73 may support each other at both ends.

Next, looking at the hinge cover 70 , the hinge cover 70 is assembled to the main cover 60 . The hinge cover 70 may move relative to the main cover 60 in a state of being assembled to the main cover 60 . When the hinge cover 70 moves relative to the main cover 60 , the overall length of the frame cover 50 may vary. More precisely, when the hinge cover 70 moves in a direction away from the main cover 60, the overall length of the frame cover 50 increases, and on the contrary, when the hinge cover 70 moves in a direction closer to the main cover 60, the frame The overall length of the cover 50 is reduced.

In this way, since the length of the frame cover 50 can be adjusted, even if the shape and size of the door assembly 20 are different, the frame cover 50 can be used as it is. In particular, as described above while comparing FIGS. 4 and 5 , even when the installation shape or thickness of the housing is slightly changed, the length of the frame cover 50 of this embodiment can be adjusted and applied.

9 and 10, the movable body 71 forming the skeleton of the hinge cover 70 is relatively shorter than the main cover 60, and is coupled with a part of the end of the main cover 60. it can be seen that When the hinge cover 70 is assembled to the door frame 40 , the hinge mounting part 45 is shielded. To this end, the hinge cover 70 has a shape corresponding to the hinge mounting portion 45 .

In this embodiment, the movable body 71 of the hinge cover 70 includes a first vertical plate 71a and a second vertical plate extending in a direction in which the frame cover 50 is assembled to the door frame 40 ( 71c) and a horizontal plate 71b connecting the first vertical plate 71a and the second vertical plate 71c in a direction perpendicular to the upper part. 11, on the outer surface of the movable body 71, there is an outer plate 71d connecting all of the first vertical plate 71a, the second vertical plate 71c, and the horizontal plate 71b.

A predetermined space is provided inside the first vertical plate 71a, the second vertical plate 71c, the horizontal plate 71b, and the outer plate 71d, and the space includes the hinge mounting part 45 and connected 18 shows a state in which the movable body 71 surrounds the hinge mounting part 45 .

The hinge cover 70 has a second assembly part 73 . The second assembly part 73 is a part assembled with the first assembly part 63 of the main cover 60, and a guide hook 75, a pressing plate 77 and a cover stopper 78 to be described below. may include all of them. Although the second assembly part 73 is assembled to the first assembly part 63, it is not completely fixed. Even when the second assembly part 73 is assembled to the first assembly part 63 , the hinge cover 70 can move relative to the main cover 60 .

The second assembly part 73 includes a hook block 74 . The hook block 74 has a substantially hexahedral shape and is provided on the second vertical plate 71c. The hook block 74 protrudes in the front direction, that is, in the front direction of the door assembly 20, and a guide hook 75 is provided in the front part thereof. A guide hook 75 is provided at the center of the hook block 74, and a pressing plate 77 and a cover stopper 78 are connected to the left and right sides, respectively.

The guide hook 75 extends upward from the hook block 74 and has a cantilever shape. Therefore, the guide hook 75 has a structure that can be elastically deformed to some extent. The guide hook 75 is fitted into the guide hole 66 of the main cover 60 when the main cover 60 and the hinge cover 70 are assembled with each other. To this end, at least a portion of the guide hook 75 protrudes so that at least a portion of the guide hook 75 can pass through the guide hole 66 .

The guide hook 75 has a locking protrusion 76 . The stopping protrusion 76 extends in a direction perpendicular to the direction in which the guide hook 75 protrudes from the end of the guide hook 75 . When the guide hook 75 is inserted into the guide hole 66 , the locking protrusion 76 is fixed to the edge of the guide hole 66 . The upper surface of the locking protrusion 76 has an inclined shape, so that the locking protrusion 76 can be easily fitted into the guide hole 66 .

On the other hand, the guide hook 75 has a second length adjustment end 76a. The second length adjustment end 76a is provided on a surface of the guide hook 75 toward the inner surface of the guide hole 66 . The second length adjusting end 76a is engaged with the first length adjusting end 66a. To this end, the second length adjusting end 76a may have a concave-convex shape corresponding to the first length adjusting end 66a. Accordingly, the second length adjusting end 76a may be engaged with at least one of the plurality of first length adjusting ends 66a.

Referring to FIG. 16 , the second length adjusting end 76a has a structure of two protrusions, and the two protrusions are fitted to the first length adjusting end 66a, respectively. Accordingly, one of the three grooves constituting the first length adjustment end 66a is empty, and the second length adjustment end 76a is directed in the direction of filling the empty groove (right direction based on the drawing). can move A state in which the second length adjusting end 76a is moved is shown in FIG. 17 .

Of course, if the number of grooves of the first length adjustment end 66a is four or more, the hinge cover 70 can move to a more subdivided step as the second length adjustment end 76a sequentially passes them. have. In the present embodiment, the first length adjustment end 66a and the second length adjustment end 76a have a substantially semicircular curved surface corresponding to each other.

As shown in FIGS. 16 and 17 , there is an empty space between the opposite surface of the second length adjusting end 76a without a protrusion structure and the inner surface of the guide hole 66 . Accordingly, the guide hook 75 may be elastically deformed in the direction of the empty space while the second length adjusting end 76a rides over the first length adjusting end 66a.

For reference, other examples of the guide hole 66 and the guide hook 75 are shown in FIG. 21 . First, referring to FIG. 21 (a), the first length adjustment end 66a is composed of a total of four grooves, the shape is not a curved surface but a flat surface, and the second length adjustment end 76a is also a planar structure. . In this embodiment, since the first length adjustment end 66a has a total of four grooves, the guide hook 75 may be disposed at three different positions while moving to the right.

Referring to FIG. 21( b ), a first length adjusting end 66a and a second length adjusting end 76a are omitted in the guide hole 66 and the guide hook 75 , respectively. That is, the inner surface of the guide hole 66 is flat, and the surface of the guide hook 75 is also flat. Accordingly, the guide hook 75 can move within the guide hole 66 without being caught. Since the spacer 48 to be described below fills the space between the main cover 60 and the hinge cover 70, the guide hook 75 can be fixed at a specific position even if it is not caught in the guide hole 66. .

Referring to FIG. 21( c ), one side of the guide hook 75 has a second length adjusting end 76a , which is a plurality of protrusions toward the first length adjusting end 66a , and the guide hook 75 ), a support protrusion 76b protrudes from the opposite surface. The support protrusion 76b protrudes in a direction to fill the empty space of the guide hole 66 to limit the extent to which the guide hook 75 is elastically deformed. Accordingly, it is possible to prevent the guide hook 75 from being excessively elastically deformed to cause a whitening phenomenon or to be damaged.

Referring to FIG. 21( d ), first length adjustment ends 66a and 66b are respectively provided on both inner surfaces of the guide hole 66 , and second length adjustment ends 76a on both surfaces of the guide hook 75 , respectively. , 76b). Accordingly, the first length adjusting ends 66a and 66b and the second length adjusting ends 76a and 76b may be engaged with each other on both surfaces. And a deformable slit 66c passes through the assembly plate 65, and the deformable slit 66c allows the guide hook 75 to be more easily elastically deformed.

On the other hand, in this embodiment, the hinge cover 70 has a guide hook 75 and the main cover 60 has a guide hole 66. Conversely, a guide hole is formed in the hinge cover 70 and , a guide hook may protrude from the main cover 60 . In this case, the guide hook may protrude from top to bottom toward the door frame 40 .

Referring back to FIG. 10 , a pressing plate 77 is connected to the hook block 74 . The pressing plate 77 is provided on the second vertical plate 71c, and protrudes in a direction perpendicular to the surface of the second vertical plate 71c. The pressing plate 77 is a portion stacked under the assembly plate 65 of the first assembly part 63 and is pressed downward by the assembly plate 65 .

Referring to FIG. 18 , it can be seen that the assembly plate 65 is positioned on the pressing plate 77 . There is an overlap section M between the assembling plate 65 and the pressing plate 77, and the assembling plate 65 presses the pressing plate 77 downward, that is, toward the bottom surface of the hinge mounting part 45. .

At this time, the hinge cover 70 is positioned between the main cover 60 and the door frame 40, and since the main cover 60 is assembled and fixed to the door frame 40, the main cover 60 ) may press the pressing plate 77 with the assembling plate 65 in a fixed state. In this way, the hinge cover 70 can maintain a firmly fixed state without moving in the vertical direction.

Referring back to FIG. 10 , there is a cover stopper 78 on the opposite side of the pressing plate 77 with respect to the guide hook 75 . The cover stopper 78 protrudes in the relative movement direction of the main cover 60 and the hinge cover 70 . The cover stopper 78 serves to limit the movement of the hinge cover 70 by contacting the main cover 60 while the hinge cover 70 moves relative to the main cover 60 .

The cover stopper 78 is positioned between the assembly plate 65 and the stopper engaging end 69, and in the process of left and right movement of the hinge cover 70, the assembly plate 65 and the stopper engaging end 69 ) can take In this embodiment, a part of the stopper engaging end 69 protrudes in the relative movement direction of the main cover 60 and the hinge cover 70 , and the protruding end interferes with the stopper engaging end 69 . The cover stopper 78 may be omitted.

And, referring to FIG. 9 , the stopper engaging end 69 supports the front portion of the cover stopper 78 from below. When the stopper engaging end 69 supports the cover stopper 78 from below, it is possible to prevent the hinge cover 70 from being excessively pressed in the direction of the door frame 40 .

The hinge cover 70 has a position fixing part 79 . The position fixing part 79 is provided at the lower part of the hinge cover 70, and has an approximately 'L' shape. The end portion of the position fixing portion 79 protrudes downward and is caught on the edge of the hinge mounting portion 45 of the door frame 40 . As shown in FIGS. 18 and 19 , when the position fixing part 79 is caught on the edge of the hinge mounting part 45 , the hinge cover 70 can be prevented from protruding to the outside of the door frame 40 . have.

Next, looking at the process of assembling the frame cover 50 , as shown in FIGS. 10 and 11 , the main cover 60 is assembled from the top to the bottom with the hinge cover 70 underneath. At this time, the guide hook 75 of the second assembly part 73 may be naturally fitted into the guide hole 66 of the first assembly part 63 .

This is because a portion of the surface of the main cover 60 and a portion of the surface of the hinge cover 70 are in surface contact with each other to form a contact surface P, so that they can be assembled in a certain direction. In particular, the contact surface P is formed with a flat surface and a curved surface along the direction in which the hinge cover 70 moves relative to the main cover 60, and these shapes are the main cover 60 and the hinge cover ( 70) provides a structure that engages each other, and thus allows them to be assembled in a constant vertical direction without sliding in the left and right directions.

When the guide hook 75 is inserted into the guide hole 66 , the locking protrusion 76 is caught on the edge of the guide hole 66 , and a space between the main cover 60 and the hinge cover 70 is temporarily assembled. As described above, in this embodiment, the first assembly part 63 of the main cover 60 and the second assembly part 73 of the hinge cover 70 are the frame cover 50 and the door frame 40 . They are assembled to each other in the same direction as they are assembled to each other.

When the main cover 60 and the hinge cover 70 are assembled to each other in the same direction as the assembly direction to the door frame 40, the assembly plate 65 attaches the pressing plate 77 to the door frame 40. direction, and it is possible to prevent the flow of the hinge cover 70 .

Next, a process of relative movement of the hinge cover 70 with respect to the main cover 60 will be described with reference to FIGS. 12 to 17 . For reference, FIGS. 12, 14 and 16 show a state in which the hinge cover 70 moves away from the main cover 60, and FIGS. 13, 15 and 17 show that the hinge cover 70 is the main cover. (60) is an expression of the state approaching.

12 and 14 , the hinge cover 70 is moved in a direction away from the main cover 60 . In this case, the overall length of the frame cover 50 is in a long state. Therefore, even when the thickness of the housing constituting the side surface 22 of the door assembly 20 is thick, it can match the side line (refer to L2 of FIG. 5 ) of the housing.

However, when the side of the hinge cover 70 does not match the side line L1 of the housing because the thickness of the housing is thin as shown in FIG. 14 , the overall length of the frame cover 50 must be reduced. To this end, when the operator presses the hinge cover 70 in the direction of the main cover 60 , that is, in the direction of the arrow in FIG. 14 , the guide hook 75 moves while being inserted into the guide hole 66 .

In this process, the second length adjusting end 76a of the guide hook 75 can move step by step while riding over the first length adjusting end 66a of the guide hole 66 . The user can press the hinge cover 70 while overcoming the elastic force of the guide hook 75 generated when the second length adjustment end 76a rides over the first length adjustment end 66a. 13 and 17 show the state in which the hinge cover 70 is moved through this process.

In this case, the guide hook 75 is positioned on the inner surface of the guide hole 66 , and the overall length of the frame cover 50 is shortened. 15 , it can be seen that the hinge cover 70 moves toward the main cover 60 so that the side surface of the hinge cover 70 coincides with the side line L1 of the housing. Of course, the operator may adjust the length of the frame cover 50 in advance before the frame cover 50 is assembled to the door frame 40 .

In addition, the overall length of the frame cover 50 may be adjusted according to the thickness of the exterior material, but the length may be adjusted to compensate for this even when the door frame 40 or the frame cover 50 itself is manufactured outside the tolerance. . In this embodiment, since the door frame 40 has a narrow width and a long length, there is a fear that it may be twisted or contracted during the injection molding process. 40) to fit the length. When the length of the frame cover 50 is adjusted to the length of the door frame 40 in this way, the outer surfaces of the door frame 40 and the frame cover 50 may constitute a continuous plane.

On the other hand, the operation of increasing the length of the frame cover 50 is performed opposite to the previous process. When the operator pulls the hinge cover 70 away from the main cover 60 , the second length adjustment end 76a of the guide hook 75 is the first length in the guide hole 66 . It moves while riding over the adjustment end (66a).

In the process of moving the hinge cover 70 , the extent to which the cover stopper 78 of the hinge cover 70 comes into contact with the main cover 60 and moves outward may be limited. And the stopper engaging end 69 of the main cover 60 supports the front part of the cover stopper 78 from below. In this case, the overall length of the frame cover 50 is increased.

Of course, even if the operator does not move the hinge cover 70 one by one, the length of the frame cover 50 may naturally increase by the spacer 48 described above. The spacer 48 is formed in a thin plate shape at a position corresponding to between the main cover 60 and the hinge cover 70 , and the spacer 48 has a frame cover 50 attached to the door frame 40 . It protrudes along the bonding direction. Accordingly, in the process of assembling the frame cover 50 to the door frame 40, the spacer 48 is naturally inserted between the main cover 60 and the hinge cover 70, and the hinge cover 70 and the main cover (60) It can widen the gap.
