Description

Technology area

[0001] This document discloses a laundry treating device having a hook fastening structure between an outer frame and an inner door frame.

State of the art

[0002] Basically, an apparatus for treating laundry may include an apparatus having a function of washing or drying laundry or other articles (hereinafter, collectively, “laundry”). In addition, the laundry treating device may be configured to have both a washing function and a laundry drying function.

[0003] The laundry treating apparatus may include a main body having a laundry loading opening, a door configured to open and close the laundry loading opening, and a laundry receiving portion formed in the cabinet. The door may include a door frame, a front glass mounted on the front surface of the door frame, and a door window mounted on the door frame to protrude through the laundry loading opening.

[0004] The door frame may include an outer frame located on the outer side of the main body and an inner frame located on the inner side of the main body when the door is closed. Each of the outer frame and the inner frame in the prior art is fixed with a screw in a fixing hole. In the outer frame and the inner frame in the prior art, the weight of the front glass is large, and thus the clamping force between the outer frame and the inner frame must be increased to support the front glass.

[0005] In the prior art, Korean Patent No. 10-0595180, issued June 23, 2006, and hereinafter "Patent Document 1", which is incorporated herein by reference, discloses a door of a tumble dryer / washing machine. According to Patent Document 1, a plurality of hooks may be spaced apart from each other on the upper and lower inner sides on the outer edge of the outer door frame, and the plurality of hook grooves are configured to match the plurality of hooks on the outer edge of the inner door frame. When assembling the door, the hooks of the outer doorframe and the hook grooves of the inner doorframe may engage with each other.

[0006] However, Patent Document 1 has a drawback in that moisture penetrates through the gap between the outer door frame and the inner door frame, or heated air inside the main body flows out even when a plurality of hooks and hook grooves are connected to each other. To overcome this drawback, a sealing element such as a sealant must be positioned between the outer door frame and the inner door frame. However, even in this case, the sealing member cures when the usage time expires, and it is inconvenient to replace it when the sealing function is not performed properly.

[0007] In the prior art, Korean Patent No. 10-1708352, issued February 14, 2017, and hereinafter “Patent Document 2”, which is incorporated herein by reference, discloses an apparatus for treating laundry. According to Patent Document 2, the connection between the outer frame and the inner frame can be made by screw connection, hook connection or adhesive connection, for example.

[0008] However, when the outer frame and the inner frame are screwed together, in order to increase the clamping force between the outer frame and the inner frame, the number of fixing holes and screws must be increased, which causes the problem that the cost is increased due to the increase in the number of work processes and labor time. ... In addition, when the fastening holes between the outer frame and the inner frame do not coincide with each other, fastening is not possible. Thus, there is a problem in that rework is required due to the occurrence of defective elements, or the cost of material is wasted due to the need to discard the defective elements.

[0009] On the other hand, when the outer frame and the inner frame are connected to each other by a hook structure, the problem caused by the screw connection can be solved, but such a simple hook connection between the outer frame and the inner frame has a limitation in the reinforcement or clamping force required to support the weight of the front glass. For example, since the hook connection between the outer frame and the inner frame cannot support the weight of the front glass, the outer frame hook or the inner frame hook may deform in the direction of gravity and disengage the hook connection. As a result, the outer frame and the inner frame may be separated from each other, causing damage to the door, and cracking of the front glass may occur when the front glass is separated from the door frame.

[0010] In addition, when the outer frame and the inner frame are bonded to each other with an adhesive, for example, there is a problem that the assembly process between the outer frame and the inner frame and the process of applying the adhesive are difficult. For example, in order to apply an adhesive, the application process must be carried out while the outer frame and the inner frame are pre-assembled with each other, and thus the problem arises that the hook or screw connection for pre-assembly must precede and the adhesive must be applied evenly between the outer frame and the inner frame.

[0011] In addition, even after the adhesive is applied, a problem may arise that the adhesive passes between the outer frame and the inner frame by gravity. In addition, there is a problem in that the time period for drying the adhesive after the adhesive is applied, and thus the production time, is increased.

[0026] FIG. 1 is a perspective view of a laundry treating device according to an embodiment. The laundry treating device may include a main body 10, a tub, a drum, and a door 12.

[0027] The main body 10 may form the outer shape or appearance of the laundry treating apparatus. The main body 10 may have the shape of a rectangular parallelepiped.

[0028] The main body 10 may include a front panel 101 defining the front surface of the laundry treating device, a rear panel defining the rear surface of the laundry treating device, side panels defining the sides of the laundry treating device, a top panel defining an upper surface the laundry treating device; and a bottom panel defining the bottom surface of the laundry treating device. The rear panel and side panels can be formed in a "n" shape by folding one rectangular plate, thereby increasing the structural rigidity of the main body 10.

[0029] The laundry loading opening 102 may be formed in a circular shape on the front panel 101 (see FIG. 5). The laundry loading opening 102 may pass through the front panel 101 to allow the laundry to be loaded into the laundry receiving portion through the laundry loading opening 102.

[0030] The laundry loading hole 102 may be formed on the front panel 101, and a recess 103 may be recessed towards the inner side of the main body 10 to surround the laundry loading hole 102. The laundry inlet 102 may extend through the inner side of the recess 103. A portion of the door 12 may be received in the recess 103.

[0031] The door may be pivotally connected to the front panel 101 via a hinge assembly 24 to open and close the laundry loading opening 102. The laundry holding portion may be formed inside the main body 10. The laundry holding portion may include a drum for performing a drying function, or a tub and drum for performing washing and drying functions.

[0032] In one embodiment, to perform the drying function together with the washing function, the tub and drum may be installed inside the main body 10. The tub may be formed in a cylindrical shape. The central axis of the tank can be horizontal or inclined at a predetermined angle in the direction of the tank length. There may be water in the tub for washing. The drum can be rotatably mounted inside the tank.

[0033] A liner may be disposed at the front end of the tub to communicate with the laundry loading opening 102 to prevent wash water contained within the tub from leaking into the area for housing the main body 10. The drum may be rotatably mounted relative to the tub within the tub.

[0034] The front portion of the drum may be open and in communication with the laundry loading opening 102. The laundry can be placed inside the drum through the laundry loading opening 102.

[0035] The drive motor may be mounted on the rear surface of the tub, and the drive motor may be connected to a rotating shaft on the rear surface of the drum to rotate the drum by transmitting the drive motor power to the drum through the rotating shaft when driving the drive motor. The plurality of through holes may be located on a peripheral surface of the drum to allow fluid such as wash water to flow into and out of the drum through the plurality of through holes. The drum may have a plurality of lifting protrusions for rotating the laundry disposed within the drum, thereby performing the washing and drying functions.

[0036] The controller 11 may be located in or on the main body 10, or located in or on the door 12. In this embodiment, the controller 11 is located above the front panel 101 of the main body 10.

[0037] The controller 11 may be configured to display information related to modes of operation of the laundry treating device to a user and receive data input by the user. Controller 11 may include a knob and a plurality of buttons for receiving user input. In addition, the controller 11 may include a display that displays visual information.

[0038] Fig. 2 is a front view of the door 12 in Fig. 1. FIG. 3 is an exploded perspective view of the door 12 in FIG. 2. FIG.

[0039] The door 12 may include a door frame 13, a door window 23, a front glass 20, a hinge assembly 24, and a locking assembly 30. The door frame 13 may have an annular shape.

[0040] 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 from a synthetic resin such as acrylonitrile butadiene styrene or polycarbonate, for example. Each of the outer frame 14 and the inner frame 19 can be made by injection molding, for example, when made from synthetic resin.

[0041] Each of the outer frame 14 and the inner frame 19, respectively, may have an annular shape, and they may overlap and be fixed with each other in the front-to-back direction. The fastening structure between the outer frame 14 and the inner frame 19 will be described below.

[0042] The outer frame 14 and the inner frame 19 are respectively named when the outer frame 14 is located on the outer side of the main body 10 and the inner frame 19 is located on the inner side of the main body 10 based on the position in which the door 12 is closed. The outer frame 14 may be referred to as the “first frame” and the inner frame 19 may be referred to as the “second frame”.

[0043] Circular holes 18 may be formed to match each other on the outer frame 14 and the inner frame 19, respectively. The holes 18 may be offset from the center of each of the outer frame 14 and the inner frame 19. For example, the center of the hole 18 may be located above the center of each of the outer frame 14 and the inner frame 19.

[0044] According to this embodiment, each of the outer frame 14 and the inner frame 19 may vary in width in the circumferential direction. In other words, the distance (width) between the outer diameter and the inner diameter (hole diameter 18) of each of the outer frame 14 and the inner frame 19 can increase (expand) from the upper end to the lower end.

[0045] The center of the drum can be located above the center of height (1/2) of the main body 10. The drum can be fixed in the direction of the height of the main body 10, regardless of vibrations per minute due to rotation.

[0046] Consumers prefer the larger size of the door 12 relative to the same volume and size of the washing machine when viewed from the front of the cabinet 10. In addition, consumers can look into the drum through the door 12 and, if possible, prefer to have a wide field of view relative to the interior of the drum.

[0047] To meet the needs of the aforementioned consumers, the door 12 must be extended downward to increase the size of the door 12, while the position of the drum is fixed. The center of the door frame 13 should move below the center of the laundry loading opening 102 or opening 18. Similarly, the center of the door frame 13 can move downwardly relative to the door window 23 positioned to match the opening 18.

[0048] In addition, to increase the size of the door 12, a portion of the door 12 may protrude outwardly from the recess 103. The diameter of the door 12 may be larger than the recess 103.

[0049] The front glass 20 may be formed in a circular shape having a predetermined radius. Front glass 20 can be made of glass.

[0050] Front glass 20 can have flat front and back surfaces. The front glass 20 can be disc-shaped having a constant thickness, without bending, when viewed from any direction, up, down, left or right.

[0051] As described above, the front and rear surfaces of the front glass 20 made of glass may have a flat circular shape, thus improving the quality of the door 12 over a prior art door cover made of synthetic resin, which has convex anterior surface in an incomplete round shape.

[0052] The transparent alignment mark 221 may be formed on the opaque region 22. The alignment mark 221 may be a member for guiding the alignment position of the front glass 20 relative to the outer frame 14. In this embodiment, the circular alignment mark 221 is located on the underside (6 o'clock direction) front glass 20. However, the embodiments are not necessarily limited to this. The alignment mark 221, for example, may be formed in a polygonal shape or may be formed in a linear shape. Of course, the position of the alignment mark 221 can be changed.

[0053] The front glass may include a transparent region 21, an opaque region 22, and an alignment mark 221 in a laminate in a laminated structure. For example, the front glass 20 may include a glass body made of clear glass and a protective layer disposed to cover the rear surface of the glass body to form an opaque region 22. In this case, a portion where the protective layer is not located may form a transparent region 21 and alignment mark 221. The protective layer, for example, can be made by means of glass printing on the back surface of the glass body.

[0054] As another example, the front glass 20 may include a glass body made of clear glass and a film disposed to cover the rear surface of the glass body. The film may include a transparent portion positioned with transparency corresponding to the transparent region 21, an opaque portion positioned with an opacity corresponding to the opaque region 22, and an alignment mark 221 positioned with transparency corresponding to the alignment mark 221.

[0055] As another example, the front glass 20 may include a glass body made of clear glass and a film disposed to cover the back surface of the glass body. There is a difference from the above example in that the film includes a first hole positioned to match the transparent region 21, an opaque portion positioned with an opacity corresponding to the opaque region 22, and a second hole positioned to match the alignment mark 221. In other words, there is a difference in whether the transparent region 21 and the alignment mark 221 are disposed on the transparency film or have a perforated shape.

[0056] The front glass 20 may cover the opening 18 of the door frame 13. The front glass 20 may be adhered to the front surface of the outer frame 14 using an adhesive sealant or adhesive.

[0057] Due to the nature of the glass, the front glass 20 can easily break when a fixing hole is drilled therein, and thus the front glass 20 is fixed to the outer frame 14 using an adhesive, for example, to prevent the glass from breaking. On the other hand, the front glass 20 made of glass has a relatively large load compared to the overall load of the door 12. To support the load of the front glass 20, a locating rail 34 that mounts the front glass 20 may be located on the front surface of the outer frame 14.

[0058] In particular, the front glass 20 may be made of tempered glass. Due to the nature of the tempered glass, the front and rear surfaces of the front glass 20 have high strength, but the circular outer peripheral surface that is the side surface of the front glass 20 has low strength. To compensate for this, the locating rail 34 may extend forward from the front outer peripheral end of the outer frame 14 to surround the outer peripheral surface of the front glass 20 to support the load of the front glass 20 and also to protect the side or outer peripheral surface of the front glass from external impact.

[0059] The projection length of the positioning rail 34 may be formed to cover at least 2/3 of the thickness of the front glass 20. The reason is that an external shock load can be applied to the outer peripheral surface of the front glass 20, and the load of the front glass 20 cannot be sufficiently supported when the protrusion length of the positioning rail 34 is too short.

[0060] For example, a straight portion 202 and a plurality of curved portions 201, 203 may be formed on the outer peripheral surface of the front glass 20 (see FIG. 7). The plurality of bent portions 201, 203 may include a first bent portion 201 coupled to the front surface of the front glass 20 and a second bent portion 203 coupled to the rear surface of the front glass 20. Each of the bent portions 202, 203 can have a predetermined curvature and be formed in a curved shape.

[0061] The straight portion 202 may be located between the first and second curved portions 201, 203 and connect to the first and second curved portions 201, 203, respectively. Each of the first curved portion 201, the straight portion 202 and the second curved portion 203 may be 1/3 the thickness of the front glass 20.

[0062] The positioning rail 34 may cover the second curved portion 203 and the straight section 202 of the front glass 20. The positioning rail 34 may protrude from the front edge of the outer frame 14. The positioning rail 34 may extend in an annular shape to form an area in which the front glass 20 is located. ...

[0063] The locating guide 34 may have a predetermined inner diameter to form a circle. The inner diameter of the positioning rail 34 may match the outer diameter of the front glass 20, and thus the positioning rail 34 can surround the outer peripheral surface of the front glass 20.

[0064] The transparent area 21 and the opaque area 22 may be located on the inner and outer sides of the front glass 20, respectively. The transparent area 21 means an area capable of transmitting at least a portion of the light so that the inside of the laundry receiving area can be seen by the user. Therefore, the transparent area 21 may include a light transmission area.

[0065] The transparent area 21 may be positioned to match the opening 18 of the outer frame 14, the opening 18 of the inner frame 19, and the door window 23. While the door 12 is closed, the user can see the laundry receiving area through the transparent area 21.

[0066] The center of the transparent region 21 may be located at a position corresponding to the center of the opening 18 of each of the outer frame 14 and the inner frame 19. The corresponding position may include not only excellent center alignment, but also offsets in the center offset direction. In other words, the center of the transparent region 21 and the center of the hole 18 may coincide, and the displacement direction of the transparent region 21 may be the same as the displacement direction of the hole 18.

[0067] In this embodiment, the center of the opening 18 is offset from the center of the door frame 13 toward the top side (12 o'clock direction), and accordingly, the center of the transparent region 21 is also located from the center of the front glass 20 toward the top side (12 o’clock direction) ... The center of the transparent area 21 and the center of the hole 18 may coincide.

[0068] The opaque region 22 may surround the transparent region 21. The opaque region 22 does not transmit light, and thus the glass itself may appear black in the opaque region 22. The opaque region 22 may cover the rest of the door frame 13 except for the opening 18 and the region the door frame 13. The boundary line between the transparent area 21 and the opaque area 22 surrounding the transparent area 21 can be clearly distinguished from the opaque area 22.

[0069] The boundary line between the transparent area 21 and the opaque area 22 surrounding the transparent area may be clearly visible by the opaque area 22. Alternatively, the boundary between the transparent area 21 and the opaque area 22 may be fuzzy due to the grayscale method, thus providing a visual transition from the transparent region 21 to the opaque region 22. The opaque region 22 may include a plurality of security dots around the transparent region 21, and the plurality of security dots may be arranged at a density decreasing towards the transparent region 21.

[0070] The outer frame 14 may include a flat portion 15 and a curved portion 16. The flat portion 15 may be in contact with the rear surface of the front glass 20 and a portion of the flat portion 15 may overlap with the opaque area 22. The adhesive may be applied to the flat section 15 so that the front glass 20 can be adhered to the flat section 15.

[0071] The adhesive groove 37 for placing the adhesive on the front surface of the flat portion 15 of the outer frame may be recessed in the thickness direction of the flat portion 15 on the front surface of the flat portion 15. The adhesive can be placed in the adhesive groove 43 and the rear surface of the front glass 20 can be glued to the flat area 15 with an adhesive.

[0072] The adhesive may flow radially onto the outside or the inside of the adhesive groove 43 when the adhesive groove 43 is filled. To accommodate the adhesive flowing out of the adhesive groove 43, the adhesive drainage grooves 441, 442 may be recessed in an annular shape on the inner side and the outer side of the adhesive groove 43, respectively (see FIG. 6).

[0073] The adhesive groove 43 and the plurality of adhesive discharge grooves 441, 442 may extend in the circumferential direction of the outer frame 14. The adhesive groove 43 and the plurality of adhesive discharge grooves 441, 442 may be radially disposed on the outer side of the flat portion 15. The opaque region 22 of the front glass 20 may cover an adhesive groove 43 and a plurality of adhesive draining grooves 441, 442 of the flat portion 15.

[0074] The plurality of adhesive discharge grooves 441, 442 may include a first adhesive discharge groove 441 and a second adhesive discharge groove 444. The first adhesive discharge groove 441 may have an annular shape on the outside of the radially filling groove 43. The second adhesive discharge groove 442 may have an annular shape on the inner side of the adhesive groove 43. The plurality of adhesive drain grooves 441, 442 may receive the adhesive when the adhesive is poured into the adhesive groove 43 after filling with the adhesive.

[0075] The plurality of water drain holes 48 may be disposed to penetrate on the underside of the flat portion 15 in the thickness direction to drain water or moisture (liquid) formed between the rear surface of the front glass 20 and the front surface of the outer frame 14 to the outside doors 12 through a plurality of water drain holes 48.

[0076] The curved portion 16 may be bent in an arcuate shape having a predetermined curvature at the outer periphery of the opening 18 of the inner frame 19 from the inner end of the flat portion 15. The inner portion of the flat portion 15 and the curved portion 16 may overlap with the outer edge of the transparent region 21. The opening 18 may be located on the inner side of the curved portion 16 in the radial direction.

[0077] The mounting rail 34 may protrude from the flat portion 15 in a circumferential direction at the outermost portion of the flat portion 15. The mounting rail 34 of the outer frame 14 may surround the outer peripheral surface of the front glass 20, thus preventing radially outward separation of the outer peripheral surface of the front glass 20 from the flat section 15 of the outer frame 14.

[0078] The plated layer 17 may be located on the front and outer peripheral surfaces of the outer frame 14 by, for example, chrome plating. The outer frame 14 can be completely immersed in the chrome plating solution, and thus the plated layer 17 can be positioned over the entire surface of the outer frame 14 by chromium plating.

[0079] The plated layer 17 may coat the outer frame 14 with a polished metallic silver color. Accordingly, the plated layer 17 can have an effect in that it looks like bright silvery round water droplets. In addition, the plated layer 17 can give a high quality feeling when viewed with the naked eye.

[0080] The door window 23 can be positioned to match the laundry loading opening 102 when the door 12 is closed. The door window 23 can be mounted on the door frame 13 to match the opening 18 of the inner frame 19.

[0081] The door window 23 may be made of a transparent material such as a synthetic resin having a high transmission property so that the interior of the laundry receiving portion such as a drum can be seen through the door window 23. The door window 23 may not necessarily limited to synthetic material, and can also be made of glass.

[0082] The outer edge of the door window 23 can be inserted between and connected to the outer frame 14 and the inner frame. The outer edge of the door window 23 may be flat and can be secured between the rear end of the curved portion 16 of the outer frame 14 and the inner end of the inner frame 19.

[0083] The first portion of the outer frame 14 and inner frame 19 may protrude forward from the recess 103 in the closed position of the door 12, and the second portion of the outer frame 14 and the inner frame 19 may be received in the recess 103.

[0084] The flat portion 15 of the outer frame 14 may be located on the outside of the recess 103 and protrude forward from the recess 103, and the rear end of the curved portion 16 of the outer frame 14 may be positioned within the recess 103.

[0085] The front portion of the outer periphery of the inner frame 19 may protrude outwardly from the recess 103, and the rear portion of the outer periphery of the inner frame 19 may be located in the recess 103. The front glass 20 may be spaced outwardly and forwardly from the recess 103 and is located vertically.

[0086] The door 12 may be pivotally mounted back and forth with respect to the main body 10 by the hinge assembly 24. The hinge assembly 24 may include a hinge 25, a hinge holder 28, and a bushing 29.

[0087] The hinge 25 may be secured to the main body 10 and pivotally coupled to the door frame 13. The hinge 25 may include a plate base 26 coupled to the main body 10 and a pivotable connecting portion 27 that projects from the base 26 and pivotally coupled to the door frame 13. A plurality of pivot connecting portions 27 may be formed and spaced apart from each other in the vertical direction.

[0088] The hinge holder 28 may be coupled to the door frame 13 to support a plurality of pivot joint portions 27 to prevent the plurality of pivot joint portions 27 from separating from the door frame 13. A bushing 29 may be inserted onto the rotating shaft of the pivot joint portion 27 to effectively rotate the rotating shaft ...

[0089] The hinge assembly 24 may be mounted on one or the first side of the door 12, and the locking assembly 30 may be mounted on the other or second side of the door 12. The locking assembly 30 is configured to lock or unlock the door 12 relative to the housing 10.

[0090] The blocking assembly 30 may include a shaft 31, a door latch 32, and a spring 33. The shaft 31 may pass through the door latch 32 and be mounted on the door frame 13. The spring 33 has a resilient force to stretch as the door latch 32 pivots. In accordance with this embodiment, the door latch 32 may be configured to pivot and return to the door frame 13 to lock or unlock the door 12 relative to the main body 10.

[0091] Fig. 4 is a rear view of the door 12 in Fig. 2, Fig. 5 is a cross-sectional view showing a state in which the door 12 is mounted on the front panel 101 of the main body 10 to close the laundry loading opening 102, Fig. 6 is a cross-sectional view of the hook fastening structure between the outer frame 14 and the inner frame 19 along the line VI-VI in Fig. 4; Fig. 7 is a cross-sectional view of the hook fastening structure between the outer frame 14 and the inner frame 19 containing the handle 35 along the line VII-VII in FIG. 4, and FIG. 8 is a view showing a state in which the hook is partially disposed on the handle 35 when viewed from the front of the inner frame 19 in FIG. 4.

[0092] FIG. 5 shows the state where the controller in FIG. 1 is removed from the top side of the front panel 101. As shown in FIGS. 4 and 5, the handle 35 may be recessed on the rear top side of the inner frame 19, so that the user can open the door 12 by gripping the handle 35. The rear surface of the inner frame 19 can be convex backward in a curved shape.

[0093] A handle 35 may be located on the door 12 for opening and closing the door 12 by a user. In the prior art, the handle is typically located on the front side of the door. However, in embodiments, since the front glass 20 is configured to cover the front surface of the door 12, it is difficult to position the handle 35 on the front glass 20. Thus, the handle 35 is not located on the front surface of the door 12 due to the front glass 20, but rather may be located on the rear surface of the door 12. The handle 35 can be located on the inner frame 19.

[0094] In addition, the handle 35 may be located at the upper portion of the door 12 for easy grip by the user of the door 12. When the handle 35 is located at the lower portion of the door 12, the user must bend more at the waist or knees to grip the handle 35.

[0095] In addition, since the hinge assembly 24 and the locking assembly 30 are located, respectively, on the sides of the door frame 13 along a horizontal center line that horizontally passes through the center of the door frame 13 in the radial direction, they can be located above the horizontal center line ... In addition, the handle 35 can be positioned above the door frame 13 to be higher than the locking assembly 30 to open and close the door 12 with less force.

[0096] The handle 35 may be located on the rear upper side of the inner frame 19. When the door 12 is closed, the handle 35 may be located on the upper right side to be above the blocking assembly 30 when viewed from the front of the main body 10, i.e. within an interval of 1-3 hours in a circular direction in a clockwise direction.

[0097] The handle 35 may be recessed on the rear surface of the inner frame 19. The handle 35 may have an arcuate shape along a partial cut in the circumferential direction on the rear surface of the inner frame 19. The handle 35 may be thin and flat compared to the outer periphery of the inner frame 19 (area excluding handle 35).

[0098] According to this structure, when the door is closed by the user, the handle 35 is recessed in front of the rear outer periphery of the inner frame 19 and is formed in a flat shape when viewed from the front of the main body 10, thus facilitating the insertion of the user's hand into the handle 35 thus facilitating the placement of the user's hand on the handle 35 as well as making it easier to determine the position of the handle 35 in the closed position of the door 12.

[0099] To secure the outer frame 14 and the inner frame 19 to each other, hooks 37, 36 may be located on the outer frame 14 and the inner frame 19, respectively. The hooks 37, 36 may include a first hook 37 located on the outer frame 14 and a second hook 36 located on the inner frame 19. The first hook 37 and the second hook 36 may each be annular in the circumferential direction. The first and second hooks 37, 36 may be press fit or snap-fit to connect the outer frame to the inner frame 19, as discussed herein below.

[0100] The first hook 37 may protrude from the outer frame 14 to the inner frame 19. The first hook 37 may be disposed on the outside in the radial direction of the mounting guide 34 to surround the outer periphery of the inner frame 19. The first hook 37 may be located on the outside of the mounting rail. rail 34 when viewed from the front of the main body 10.

[0101] The locating guide 34 and the first hook 37 may be integrally connected by the protruding portion 341. The protruding portion 341 may extend from the locating guide 34 to the first hook 37. The protruding portion 341 may extend from the locating guide 34 to the first hook 37 for a gradual increase in diameter. The protruding portion 341 may have a curved shape.

[0102] Each of the locating guide 34, the first hook 37, and the protruding portion 341 may extend in the circumferential direction of the outer frame 14. According to this embodiment, the locating guide 34, the protruding portion 341, and the first hook 37 form the outer peripheral surface of the outer frame 14 in one curved shape to close the inner frame 19 so as to close the main body 10 when viewed from the front of the main body 10, thereby enhancing the appearance of the door 12. The mounting rail 34, the protruding portion 341, and the first hook 37 may each have a curved or an inclined surface shape so that its diameter gradually increases from the locating guide 34 to the first hook 37 without folds or steps.

[0103] The first hook 37 and the second hook 36 may overlap radially with each other. The first hook 37 may have a larger diameter than the second hook 36, and the second hook 36 can be inserted into the first hook 37.

[0104] The locating groove 191 may be located between the outer peripheral end of the inner frame 19 and the second hook 36 in the circumferential direction. The second hook 36 may be spaced radially inwardly from the outer peripheral end of the inner frame 19. The radial height of the locating groove 191 may be the same or similar to the thickness of the first hook 37.

[0105] According to this embodiment, when the outer frame 14 and the inner frame 19 are fixed to each other, there is no step between the outer peripheral end of the first hook 37 and the outer peripheral end of the inner frame 19, thus making the door 12 beautiful in appearance. The first hook 37 may protrude rearwardly from the outer periphery of the outer frame 14 to the inner frame 19. The hook protrusion 371 may project radially inward toward the second hook 36 on the inner peripheral surface of the first hook 37.

[0106] The second hook 36 may project forward from the outer periphery of the inner frame 19 to the outer frame 14. The hook protrusion 371 may protrude radially outwardly towards the first hook 37 on the outer peripheral surface of the second hook 36. The protrusion 371 of the first hook 37 and the protrusion 361 of the second hook 36 can project parallel to each other in a radial direction.

[0107] The hook protrusions 371, 361 may be tapered at each end of each of the first hook 37 and the second hook 36. The protrusion 371 of the first hook 37 and the protrusion 361 of the second hook 36 may axially overlap with each other. The hook protrusions 371, 361 may engage between the first hook 37 and the second hook 36 towards each other, but do not disengage them from each other in opposite directions.

[0108] Each of the protrusion 371 of the first hook 37 and the protrusion 361 of the second hook 36 may be formed with a first inclined surface in contact with the other prior to being secured, and a second inclined surface inclined on the opposite side of the first inclined surface to be in contact with each other after fixing. The first ramp and the second ramp change the angles of the hook protrusions 371 and 362 in opposite directions relative to the tops of the hook protrusions 371 and 361, respectively.

[0109] The slope angles of the first ramp surface and the second ramp surface may be different from each other. The first inclined surface of each of the hook projections 371, 361 facing each other prior to attachment may be positioned at a lower inclination angle than the second inclined surface of each of the hook projections 371 and 361 facing each other after attachment. In other words, the second inclined surface of each of the hook projections 371, 361 facing each other after being secured may have a greater inclination angle than the first inclined surface of each of the hook projections 371, 361 facing each other before being secured.

[0110] According to this embodiment, the first hook 37 and the second hook 36 are movable towards each other in the axial direction to engage the hook protrusions 371, 361 with each other, thereby securing the outer frame 14 and the inner frame 19. In addition, hook wedges 371, 361 may engage between the first hook 37 and the second hook 36 relative to each other, but prevent them from disengaging from each other in opposite directions until the first hook 37 or the second hook 36 is damaged.

[0111] In other words, when the first hook 37 and the second hook 36 move towards each other in the axial direction to secure the outer frame 14 and the inner frame 19, the resistance to movement between the hook protrusions 371, 361 before fastening can be reduced, and the protrusions 371, 361 the hooks may be restrained from moving in the disengaging direction with each other when the second ramp surfaces are brought into contact with each other after the first hook 37 and the second hook 36 are secured.

[0112] The outer frame 14 may include a resilient groove 38 and a hold-down portion to support the heavy load of the front glass and securely support the hook fastening structure between the outer frame and the inner frame 19. The hold-down portion can include a plurality of hold down ribs 39, connection ribs 40 and support ribs 41.

[0113] The elastic groove 38 may be located radially inward from the first hook 37 on the rear surface of the outer frame 14. The elastic groove 38 may be concave in the thickness direction of the flat portion 15 on the rear surface of the flat portion 15 of the outer frame 14. The elastic groove 38 may be larger concave in the thickness direction of the flat portion 15 on the inner side of the first hook 37 so that the thickness of the first hook 37 is reduced, thereby allowing the first hook 37 to resiliently deform radially outward.

[0114] According to this embodiment, when the second hook 36 extends to the inside of the first hook 37 in the axial direction, the protrusion 371 of the first hook 37 may extend outward in the radial direction, while the protrusion 371 of the first hook 37 and the protrusion 361 of the second hook 36 are brought into contact with each other, thus allowing the projection 361 of the second hook 36 to pass onto the inner side of the projection 371 of the first hook 37. In addition, since the pressing force between the projection 371 of the first hook 37 and the projection 361 of the second hook 36 is weakened, in As the protrusion 361 of the second hook 36 passes through the highest point of the protrusion 371 of the first hook 37, the first hook 37 returns to its original position from the deformed state, thus allowing the protrusion 371 of the first hook 37 and the protrusion 361 of the second hook 36 to engage each other ...

[0115] The plurality of pressing ribs 39 may be disposed on the rear surface of the flat portion 15. The plurality of pressing ribs 39 may protrude from the rear surface of the flat portion 15 to bring into contact with the inner peripheral surface of the second hook 36 to hold down the second hook 36 while securing the first hook 37 with a second hook 36. The plurality of pressure ribs 39 may be spaced apart from each other in a direction along the circumference of the flat portion 15.

[0116] According to this embodiment, a plurality of pressing ribs 39 press the inner circumferential surface of the second hook 36 radially outward while securing the first hook 37 to the second hook 36. Accordingly, since the second hook 36 is not forced inward in the radial direction, the attachment position between the outer the frame 14 and the inner frame 19 can be reliably supported without axial disengagement from each other after the projections 361, 371 of each of the first hook 37 and the second hook 36 are secured to each other.

[0117] In addition, the plurality of pressure ribs 39 may press down on the second hook 36, thereby increasing the traction force between the outer frame 14 and the inner frame 19. The plurality of pressure ribs 39 may be disposed radially inward from resilient grooves 38 on the rear surface of the outer frame 14 ...

[0118] The lead-in guide surface 391 can be tilted toward an elastic groove 38 on the rear surface of the hold-down rib 39. The lead-in guide surface 391 can guide the movement of the second hook 36 to guide the second insertion hook 36 between the plurality of hold-down ribs 39 and the first hook 37. The guide surface The insertion 391 can provide for the insertion of the second hook 36 into the first hook 37, thereby increasing assembly efficiency.

[0119] The press fit or snap fit of the first and second hooks 37, 36 may operate as follows. The first oblique surface of the hook projections 371, 361, then the second oblique surface of the hook projections 371, 361 interact when the second hook 36 is inserted into the first hook 37, the first hook 37 being bent to accommodate the second hook, and the insertion guide surface 391 allows the second hook 36 to be inserted into first hook 37. After insertion or connection of the second hook 36 with the first hook 37, the second ramp as well as the plurality of pressure ribs function to maintain the connection between the first hook 37 and the second hook 36 and thus between the outer frame 14 and inner frame 19.

[0120] The connecting rib 40 may protrude rearwardly on the rear surface of the outer frame 14 and may extend in the circumferential direction in an annular shape. The connecting rib 40 can connect a plurality of pressure ribs 39.

[0121] The connecting rib 40 may protrude from the opposite side of the first adhesive drain groove 441 to the inner frame 19 at the rear surface of the flat portion 15. Some or all of the connecting ribs 40 may overlap in the thickness direction of the first adhesive drain groove 441 and the flat portion 15. According to this embodiment, the connecting rib 40 can compensate for the decrease in rigidity caused by the small thickness of one side of the flat portion due to the adhesive discharge groove 441.

[0122] The resilient groove 38 may be located between the connecting rib 40 and the first hook 37. The resilient groove 38 may have an inner inclined surface that is inclined so that the thickness of the flat portion 15 gradually decreases from the connecting rib 40 towards the first hook 37.

[0123] The plurality of support ribs 41 may protrude from the rear surface of the outer frame 14. The plurality of support ribs 41 may have a trapezoidal plate structure to extend vertically in a radial direction.

[0124] The plurality of support ribs 41 may be spaced apart from each other in the circumferential direction. One side of each of the plurality of support ribs 41 may be integrally connected to the rear surface of the flat portion 15. An outer surface perpendicular to one or the first side of the plurality of support ribs 41 may be integrally connected to the connecting rib 40, and thus , a plurality of support ribs 41 may be connected to each other by a connecting rib 40. The other or second side of the support ribs 41 located on the side opposite to the first side of the support ribs 41 may be parallel to the flat portion 15.

[0125] According to this embodiment, the plurality of support ribs 41 may be integrally disposed in direct contact with the inner surface of the connecting rib 40 and the flat portion 15 to securely support the connecting rib 40 and the plurality of pressing ribs 39.

[0126] The plurality of pressing ribs 39 and the plurality of abutment ribs 41 may face each other radially on the inner and outer sides of the connecting rib 40 by placing the connecting rib therebetween. The plurality of abutment ribs 41 may overlap with each other in the thickness direction of the adhesive groove 43 and the flat portion 15 on the rear surface of the flat portion 15. According to this embodiment, the plurality of abutment ribs 41 can compensate for the reduction in rigidity of the flat portion 15 by the adhesive groove 43 ...

[0127] The reinforcement rib 42 may protrude from the opposite side of the second adhesive discharge groove 442 located on the inner side of the adhesive groove 43 between the adhesive discharge grooves 441, 442 on the rear surface of the flat portion 15. The reinforcement rib 42 may overlap with the second groove 442 to drain the adhesive in the thickness direction of the flat portion 15. According to this embodiment, the reinforcement rib 42 can compensate for the weakening of the flat portion 15 by the adhesive drain groove 442.

[0128] The handle 35, which is a portion of the inner frame 19, has a smaller thickness than the handle 35 on the outer edge of the inner frame 19. The handle 35 does not axially cover the outer surface of the first hook 37 of the outer frame 14. Consequently, the hook fastening structure between the handle 35 and the outer frame 14 differs slightly from the hook fastening structure between the inner frame 19 and the outer frame 14.

[0129] The plurality of second hooks 47 of the handle 35 may be spaced apart in the circumferential direction of the handle 35. Each of the plurality of second hooks 47 disposed on the handle 35 may have different lengths in the circumferential direction.

[0130] The first hook 46 of the outer frame 14 and the second hook 47 of the handle 35 may protrude parallel to each other in the radial direction. The first hook 46 of the outer frame 14 may project radially inward from the inner peripheral surface of the outer frame 14, and the second hook 47 of the handle 35 may project radially outward from the outer peripheral surface of the handle 35. The first hook 46 of the outer frame 14 and the second hook 47 of the handle 35 may overlap in the thickness direction of the handle 35 to engage with each other in the thickness direction when the outer frame 14 and the inner frame 19 are fixed to each other.

[0131] The chamfer 461 can be angled at one or the first edge or side of the first hook 46. The contact portion 462 can be located substantially vertically on the other or second side of the first hook 46.

[0132] The chamfer 471 can be angled at one or the first edge or side of the second hook 47 of the handle 35. The contact portion 472 can be located substantially vertically on the other or the second side of the second hook 47 of the handle 35.

[0133] According to this embodiment, when the outer frame 14 and the inner frame 19 are fixed to each other in the front-to-back direction (axial direction). The chamfers 461, 471 are in contact with each other, thus allowing the second hook 47 of the handle 35 to enter the inner side of the first hook 46 of the outer frame 14. In addition, after the outer frame 14 and the handle 35 are secured, the contact portions 462, 472 of each of the first the hook 46 of the outer frame 14 and the second hook 47 of the handle 35 are in contact with each other substantially vertically, thus preventing them from disengaging from each other.

[0134] The elastic groove 38 may be concave in the thickness direction on the rear surface of the flat portion 15 of the outer frame 14, and thus the first hook 46 can elastically deform radially outwardly by the elastic groove when the first hook 46 is inserted on the inner side of the second hook 47 and is connected to the inside of the second hook 47. In addition, the second hook 36 can easily pass to the inside of the first hook 37 by means of the chamfers 461, 471. Also, the first hook 37 and the second hook 36 can be prevented from disengaging with each other by the account of contact areas 462, 472.

[0135] The reinforcement rib 45 may protrude toward the second adhesive discharge groove 442 on one side of the handle 35. The reinforcement rib 42 may be in contact with the opposite side of the second adhesive discharge groove 442. The reinforcing rib 45 of the handle 35 can compensate for the decrease in the strength of the flat portion 15 caused by the small thickness of the flat portion 15 by the second adhesive drainage groove 442.

[0136] In addition, the reinforcing rib 42 can serve as a spacer to maintain a constant gap between the handle 35 and the flat portion 15, thereby reducing the thickness of the handle 35. In addition, the reinforcing rib 42 can not only increase the strength of the handle 35 even when the thickness of the handle 35 is reduced, but also maintains a state of contact between the contact portion 462 of the first hook 46 and the contact portion 472 of the second hook 47. Accordingly, the connection and assembly efficiency of the outer frame 14 and the inner frame 19 can be improved by the fastening structure between the first hook 46 of the outer frame 14 and the second hook 47 of the handle 35.
