Detailed Implementation

[0030] Hereinafter, the refrigerator door frame, refrigerator drawer door, and refrigerator according to embodiments will be described with reference to the accompanying drawings. In the following description, structures with the same or similar functions will be labeled with the same reference numerals. Sometimes, repeated descriptions of structures will be omitted. In this specification, left and right are defined based on the direction from which the refrigerator is viewed from the front of the user. The side closest to the user standing in front of the refrigerator is defined as "front," and the side furthest away is defined as "rear." The "width direction" in this specification refers to the left-right direction as defined above. The "front-back direction" in this specification refers to the direction orthogonal to the width direction as defined above and connecting front and rear. The use of "A or B" in this application is not limited to either A or B, but includes both A and B.

[0031] Figure 1 This is a front view of the refrigerator 100 according to the embodiment. Figure 2 From Figure 1 View the side of refrigerator doors 20, 30, and 40 of refrigerator 100 from the right side. (See attached image.) Figure 1 As shown, the refrigerator 100 includes a refrigerator body 110 and multiple refrigerator doors 20, 30, and 40. The refrigerator body 110 includes a cabinet 105 and known components such as a compressor, cooling mechanism, fan, temperature sensor, and control device (not shown).

[0032] The housing 105 has multiple storage compartments 101, 102, and 103. These multiple storage compartments may be, for example, a first refrigerator compartment 101, a second refrigerator compartment 102, and a freezer compartment 103. In this embodiment, the first refrigerator compartment 101 is located at the top, the second refrigerator compartment 102 is located below the first refrigerator compartment 101, and the freezer compartment 103 is located below the second refrigerator compartment 102. The arrangement of the storage compartments 101, 102, and 103 is not limited to the above example; for example, the arrangement of the second refrigerator compartment 102 and the freezer compartment 103 may be reversed. Storage shelves, storage containers, and ice-making water containers are appropriately provided in each storage compartment.

[0033] The second cold storage compartment 102 is used as a vegetable storage compartment. The second cold storage compartment 102 is kept cold at a temperature suitable for vegetable storage, such as 1°C to 5°C. The second cold storage compartment 102 is not limited to a storage room with a suitable environment for vegetable storage, but can also be a storage room that is set to the same temperature range as the first cold storage compartment 101 and has a refrigeration function.

[0034] The freezer compartment 103 maintains cold temperatures within the freezing temperature range, for example, below -10°C. The second refrigerator compartment 102 and the freezer compartment 103 are configured to allow for arbitrary switching of the cold-keeping temperature between the freezing temperature range and the refrigeration temperature range. Therefore, the second refrigerator compartment can be used as a freezer compartment, and the freezer compartment 103 can be used as a refrigerator compartment.

[0035] The enclosure 105 includes, for example, an inner enclosure, an outer enclosure, and a heat insulation section. The inner enclosure forms the inner surface of the enclosure 105, and the outer enclosure forms the outer surface of the enclosure 105. A heat insulation section, comprising a foamed insulation material such as polyurethane foam, is provided between the inner and outer enclosures. The enclosure 105 has heat insulation properties. The enclosure 105 has an opening on the front surface side of each storage compartment for retrieving or placing stored items relative to each storage compartment.

[0036] Refrigerator 100 is equipped with refrigerator doors 20, 30, and 40. Refrigerator doors are components that can be opened and closed to block the openings of each storage compartment 101, 102, and 103. Refrigerator doors 20, 30, and 40 are located at the front of the cabinet 105. Refrigerator doors may be, for example, a rotating door 20, or drawer doors 30 and 40.

[0037] A rotating door 20 is provided in the first cold storage compartment 101. The rotating door 20 is rotatably mounted on the cabinet 105. Figure 2 As shown, the revolving door 20 has a frame member 15, a decorative panel 62, and a rear surface material 122. The frame member 15 is a rectangular frame that forms the outer contour of the revolving door 20. The decorative panel 62 is mounted on the front surface 57 of the frame member 15. The rear surface material 122 is mounted on the rear of the frame member 15.

[0038] exist Figure 1 The example shown is a single revolving door 20, but it can also be a double revolving door. In the case of a double revolving door, the left and right revolving doors can be the same size, or they can be a pair of revolving doors with different dimensions in the width direction W.

[0039] The second refrigerator compartment 102 and the freezer compartment 103 are each equipped with a drawer 17 (see reference). Figure 2 Drawer 17 constitutes a drawer-type storage section within the second refrigerator compartment 102 and the freezer compartment 103, capable of being opened and closed in the front-to-back direction D. Drawer doors 30 and 40 are provided at the front of drawer 17. Drawer doors 30 and 40 are examples of refrigerator drawer doors. Since the drawer doors 30 and 40 of the second refrigerator compartment 102 and the freezer compartment 103 have the same structure, the description will focus on the drawer door 30 of the second refrigerator compartment 102, and common parts will be labeled with the same reference numerals.

[0040] Figure 9 This is a longitudinal cross-sectional view of the approximate center of the drawer door 30 in the width direction W. Figure 10 This is a horizontal cross-sectional view of drawer door 30. Figure 11 This is the front view of the frame component 5A of drawer door 40. (Example) Figure 9 as well as Figure 10As shown, drawer doors 30 and 40 include frame components 5 and 5A, decorative panels 63 and 64, and a rear surface material 22. Frame components 5 and 5A are an example of a refrigerator door frame. Decorative panels 63 and 64 are mounted on the front surface 57 of frame components 5 and 5A. The rear surface material 22 is mounted on the rear of frame components 5 and 5A. Foamed insulation material fills the space between frame components 5 and 5A, the rear surface material 22, and the decorative panel 62. The foamed insulation material also contacts the rear surface of the decorative panel 62. The foamed insulation material stably maintains the decorative panel 62 in a fixed position with the frame components 5 and 5A. The foamed insulation material is, for example, made of polyurethane.

[0041] Figure 4 This is the main view of frame component 5. Figure 5 This is a perspective view of frame component 5. Frame component 5 forms the outer contour of drawer door 30. Figure 6 This is a perspective view of frame component 5 from the rear side. (Example) Figures 4 to 16 As shown, frame component 5 is a rectangular, three-dimensional component with thickness in the front-rear direction D when viewed from the front. Frame component 5 has a pair of vertical frames 53, an upper horizontal frame 51, and a lower horizontal frame 52. The pair of vertical frames 53, the upper horizontal frame 51, and the lower horizontal frame 52 of frame component 5 are integrally formed. Frame component 5 is, for example, a profile made of resin or steel sheet. An opening 50 is formed in frame component 5, surrounded by the pair of vertical frames 53, the upper horizontal frame 51, and the lower horizontal frame 52. The opening 50 extends through frame component 5 in the front-rear direction D.

[0042] like Figure 10 As shown, the longitudinal frame 53 includes a side wall 531, a front wall 532, and a rear wall 533. The side wall 531 is arranged along the front-rear direction D. The front wall 532 extends inward from the front end of the side wall 531 along the width direction W. The rear wall 533 extends inward from the rear end of the side wall 531 along the width direction W. In other words, the outer ends of the front wall 532 and the rear wall 533 are connected by the side wall 531. The rear end of the side wall 531 protrudes outward in the width direction W than the front end. The outer end of the front wall 532 is located inward in the width direction W than the outer end of the rear wall 533. The side wall 531 includes a plane 531a extending forward from the end of the rear wall 533, and an inclined surface 531b that slopes inward from the middle portion in the front-rear direction D toward the outer end of the front wall 532. A recess 4 is formed at the connection between the front end of the side wall 531 and the front wall 532, recessed inward toward the width direction W. The recess 4 is located behind the front wall 532, and is recessed inward in the width direction W compared to the outer end 535 of the front wall 532. The horizontal cross-sectional shape of the recess 4 is an arc-shaped recess.

[0043] like Figure 5 , Figure 6 as well as Figure 9As shown, a handle 511 is formed on the upper frame 51. The handle 511 has a downwardly recessed groove shape between the middle portion and the front end of the upper frame 51 in the front-rear direction D. Figure 2 as well as Figure 3 As shown, the handle 511 is formed over the entire area of ​​the drawer door 30 in the width direction W, and opens in the side wall 531. Therefore, the user has good accessibility to the part of the drawer door 30 that is held. The two ends of the handle 511 are open in the side wall 531, thereby making it easy to remove dust that has entered the interior of the handle 511, resulting in excellent cleaning performance.

[0044] The handle 511, viewed from above, has a roughly U-shaped form. The handle 511 has a bottom 511a and a pair of opposing vertical surfaces 511b and 511c extending upwards from the front and rear ends of the bottom 511a. The boundary portions of the bottom 511a and each of the vertical surfaces 511b and 511c form a small-diameter R-surface. The handle 511 is composed of a rectangular concave portion with straight lines. The side view of the handle 511 is also roughly U-shaped, thus giving the decorative panel 63 of the drawer door 30 a straight-line appearance. Figure 3 As shown, the decorative panel 63 and the handle 511 are integrated. Furthermore, the handle 511 has openings at both ends in the width direction W of the drawer door 30, making it easy for the user to visually confirm the handle.

[0045] A recess 4 is formed in the side wall 531 of the frame member 5, so the decorative panel 63 appears to be separated from the side wall 531. As a result, the decorative panel 63 appears to float from the frame member 5. Therefore, it is difficult to visually confirm the support for the decorative panel 63, resulting in a frameless appearance. The drawer door 30 has the visual effect of the decorative panel 63 floating from the door.

[0046] The lower frame 52 is continuously set between the lower ends of a pair of vertical frames 53.

[0047] An adhesive surface 95 for the decorative panel 63 is formed on the front surface 57 of the frame member 5. The adhesive surface 95 is formed around the front surface 57 of the frame member 5.

[0048] like Figures 4 to 6 As shown, a reinforcing part 54 is provided in the opening 50 of the frame component 5. Two reinforcing parts 54 are separately arranged in the width direction W. The reinforcing parts 54 extend from the upper frame 51 to the lower frame 52. The reinforcing parts 54 extend along the longitudinal direction V. The reinforcing parts 54 are located on the same surface as the adhesive surface 95 of the decorative panel 63 or behind the adhesive surface 95. Figure 7 as well as Figure 8 In the example shown, the reinforcement 54 is located slightly behind the adhesive surface 95. The reinforcement 54 supports the upper frame 51 from below.

[0049] like Figure 10As shown, the reinforcing part 54 has a thick-walled portion 541. The thick-walled portion 541 protrudes rearward from the rear surface 542 of the reinforcing part 54. By having a thick-walled portion 541 in the reinforcing part 54, a higher reinforcing effect can be obtained. That is, by having a thick-walled portion 541 in the reinforcing part 54, the rigidity of the reinforcing part 54 is increased. As a result, it is possible to prevent deflection of the reinforcing part 54 in the front-rear direction D. Since the thick-walled portion 541 protrudes rearward from the rear surface 542 of the reinforcing part 54, it does not hinder the installation of the decorative panel 63 relative to the frame member 5.

[0050] like Figure 6 as well as Figure 9 As shown, the upper end 544 of the thick-walled portion 541 is continuously provided with the lower surface 511d of the bottom 511a of the handle 511. By continuously providing the thick-walled portion 541 with the lower surface 511d of the handle 511, the downward load on the upper frame 51 can be supported more stably.

[0051] The structure in which the upper end 544 of the thick-walled portion 541 and the lower surface 511d of the handle 511 are continuously formed is not necessary. The upper end 544 of the thick-walled portion 541 and the lower surface 511d of the handle 511 can also be formed separately. If the upper end 544 of the thick-walled portion 541 is separated from the lower surface 511d of the handle 511, for example, in the case of manufacturing the frame component 5 by integral molding from resin, it is possible to prevent shrinkage marks from forming in the center of the width direction of the handle 511, which has manufacturing advantages.

[0052] The reinforcing part 54 is integrally formed with the frame member 5. In this embodiment, the frame body 59, handle 511, and reinforcing part 54 of the frame member 5 are integrally formed. The structure in which the reinforcing part 54 is integrally formed with the frame member 5 is not a necessary structure. For example, the frame body 59 and the reinforcing part 54 may be composed of different components, and the reinforcing part 54 may be fixed relative to the frame body 59.

[0053] A panel support portion 9 is provided at the front of the frame member 5. The panel support portion 9 is integrally formed on the frame member 5. The panel support portion 9 is formed at the front end of the frame member 5. The panel support portion 9 is formed on the outer edges of the front walls 512, 522, and 532 of the frame member 5. For example... Figure 9 As shown, the panel support portion 9 protrudes slightly forward from the upper end of the front wall 512 of the upper frame 51 and the lower end of the front wall 522 of the lower frame 52. Figure 10 As shown, the panel support portion 9 is formed by slightly protruding forward from the outer end of the front wall 532 of the longitudinal frame 53 in the width direction W.

[0054] like Figure 9As shown, a forward-protruding locking claw 94 is formed on the panel support portion 9 of the lower frame 52. The forward protrusion of the locking claw 94 is approximately equal to the thickness of the decorative panel 63. The rear end 634 of the lower side surface 633 of the decorative panel 62 abuts against the locking claw 94. The lower side surface 633 is covered by the locking claw 94. In the width direction W, the locking claw 94 is positioned in a narrower area than the lower side surface 633 of the decorative panel 63. Therefore, the front corner of the lower end of the decorative panel 63 in the width direction W is exposed. When an adult user stands in front of the refrigerator 100, the lower side surface 633 is lower than the user's eye level. Therefore, the locking claw 94 is difficult for the user to see. As a result, it appears as if the entire area of ​​the lower side surface of the decorative panel 63 is exposed, creating a frameless structure.

[0055] The panel support portion 9 of the upper frame 51 is located at the front of the handle 511. For example... Figure 9 As shown, a locking claw 93 is formed on the upper part of the panel support portion 9, protruding slightly forward from the front wall 512 of the handle 511. The forward protrusion of the locking claw 93 is shorter than the thickness of the decorative panel 63. The rear end 634 of the upper side surface 632 of the decorative panel 63 abuts against the lower part of the locking claw 93. The front end 635 of the upper side surface 632 is located forward of the locking claw 93. The rear end 634 of the upper side surface 632 is covered by the locking claw 93, while the other front portion is exposed outward. The exposed portion of the upper side surface 632 extends from the front end 635 to a position further rearward than the middle portion in the front-rear direction D. In the width direction W, the locking claw 93 is provided in a narrower range than the upper side surface 632 of the decorative panel 63. Therefore, the corner of the front end of the upper end of the decorative panel 63 in the width direction W is exposed. The locking claw 93 is only slightly exposed at the rear of the decorative panel 63, thus achieving the visual effect of exposing the entire area of ​​the upper side 632 of the decorative panel 63.

[0056] The lower side 633 of the decorative panel 63 of the drawer door 30 is protected by a locking claw 94, and the rear end 634 of the upper side 632 is protected by a locking claw 93. For example... Figure 10 As shown, the transverse sides 631 at both ends of the width direction W of the decorative panel 63 are exposed. The transverse sides 631 at both ends of the width direction W of the decorative panel 63 are disposed on the same surface as the outer end 535 of the front wall 532.

[0057] like Figure 10 As shown, a reinforcing member 7 is provided on the inner side of the longitudinal frame 53. The reinforcing member 7 is a component that strengthens the frame member 5. When the drawer door is pulled out with refrigerated items stored in the storage section, a load is applied. Therefore, the reinforcing member 7 is provided to reduce the weight of the drawer door and strengthen the frame member 5. The reinforcing member 7 is, for example, a long strip of metal such as a steel plate.

[0058] A heat insulation material filling portion 58 is formed in the gap between the reinforcing member 7 and the longitudinal frame 53. Heat insulation material filling holes 73 are formed in the longitudinal frame 53. Multiple heat insulation material filling holes 73 are formed at intervals along the longitudinal direction V. Heat insulation material is filled into the heat insulation material filling portion 58 through the heat insulation material filling holes 73. The heat insulation material is formed, for example, by filling the heat insulation material filling portion 58 with foamed heat insulation material made of polyurethane or the like from the heat insulation material filling holes 73 and then curing it. By filling the heat insulation material filling portion 58 with foamed heat insulation material, the heat insulation material is bonded to the longitudinal frame 53 and the reinforcing member 7, and the reinforcing frame member 5. Even if the reinforcing member 7 is made of steel plate, the heat insulation performance of the drawer door 30 can be improved by filling it with heat insulation material.

[0059] exist Figures 11 to 13 The image shows the drawer door 40 of the freezer compartment 103. The basic structure of drawer door 40 is the same as that of drawer door 30 of the second refrigerator compartment 102. Figure 1 As shown, drawer door 40 has a larger area when viewed from the front compared to drawer door 30. Therefore, the size of the frame component 5A of drawer door 40 is larger than the size of the frame component 5 of drawer door 30. Figure 11 As shown, frame component 5A also includes a second horizontal frame 56. The upper frame 51, lower frame 52, a pair of vertical frames 53, reinforcing part 54, and second horizontal frame 56 of frame component 5A are integrally formed. Reinforcing part 54A extends from the upper frame 51 to the second horizontal frame 56 in the longitudinal direction V. The reinforcing part 54A is larger in the width direction W than the reinforcing part 54 of drawer door 30. Figure 12 as well as Figure 13 As shown, the rear surface 542 of the reinforcing part 54A has a thick-walled part 541A that protrudes rearward from both ends in the width direction W. The second horizontal frame 56 is an example of a lower horizontal frame. An opening 55 is formed between the second horizontal frame 56, a pair of vertical frames 53, and the lower frame 52. A reinforcing part is also provided in the opening 55. The frame component 5 can be composed of a single component, or it can be a structure in which all or part of the vertical frames, horizontal frames, reinforcing parts, and the second horizontal frame are formed and assembled from different components.

[0060] Drawer doors 30 and 40 have a rear surface material 22 for the drawer at the rear of the frame components 5 and 5A. The rear surface material 22 is a component installed over approximately the entire rear area of ​​the frame component 5. The rear surface material 22 is a three-dimensional molded component made of heat-insulating resin. For example... Figure 9 as well as Figure 10 As shown, the rear surface material 22 has a portion that protrudes rearward from the frame member 5. The rear surface material 22 can be inserted into the opening of the second refrigerator compartment 102. A gasket 16 is installed at the connection between the frame members 5, 5A and the rear surface material 22, and at the outer edge of the rear surface of the drawer doors 30, 40. The gasket 16 is configured to block the gap between the drawer doors 30, 40 and the inner wall of the second refrigerator compartment 102 when the drawer doors 30 are closed.

[0061] A decorative panel 63 is installed on the panel support 9 to cover the front surface 57 of the frame component 5. The decorative panels 63 and 64 are made of a generally flat decorative material. The decorative panels 63 and 64 are, for example, thin sheets of glass, fiber-reinforced resin, ceramic, artificial marble, etc. The decorative panels 63 and 64 are customized in terms of color, pattern, and surface finish with regard to the refrigerator's aesthetic design. As an example, a glass decorative panel is shown.

[0062] Decorative panels 63 and 64 are fixed to the bonding surface 95 of the frame member 5 by adhesive. The outer edge of the rear surface of the decorative panels 63 and 64 abuts against the panel support portion 9. Adhesive is disposed and fixed between the rear surface of the decorative panels 63 and 64 and the front wall 532. The adhesive is not particularly limited to any adhesive material that can fix the decorative panels 63 and 64 to the front surface 57 of the frame member 5, such as a coating adhesive or adhesive tape.

[0063] The sides of decorative panels 63 and 64 are positioned on approximately the same plane as the outer periphery of the front end of frame component 5. For example... Figure 10 As shown, in the width direction W, the lateral side 631 of the decorative panel 63 and the outer end 535 of the front wall 532 are positioned at the same location. The side wall 531 of the frame member 5 does not protrude outward beyond the end of the decorative panel 63 in the width direction W. The side wall 531 of the frame member 5 is disposed on the same surface or inside the width direction W relative to the lateral side 631 of the decorative panel 63. The lateral side 631 of the decorative panel 63 is disposed on the same surface or outside the width direction W relative to the outer end 535 of the front wall 532 constituting the panel support portion 9. Figure 9 As shown, the upper side 632 of the decorative panel 63 is positioned at approximately the same height as the panel support portion 9 of the upper frame 51.

[0064] The two lateral sides 631, upper side 632, and lower side 633 of the decorative panel 63 in the width direction W are exposed at least at their front ends 635 and supported by the frame member 5. That is, the frame member 5 is arranged on the same surface or inside the decorative panel 62 relative to the lateral side 631 and upper side 632, and the locking claw 94 covers the rear end 634 of the lower side 633 of the decorative panel 63. Therefore, the frame member 5 is difficult for a user standing in front of the refrigerator 100 to see, and a frameless appearance with only the decorative panel 63 exposed is obtained. As a result, the drawer doors 30 and 40 have excellent appearance design.

[0065] In this embodiment, an example is shown with three refrigerator doors 20, 30, and 40 for a first refrigerator compartment 101, a second refrigerator compartment 102, and a freezer compartment 103, but the refrigerator configuration is not limited to this. Any number of refrigerator doors can be provided depending on the number and size of the refrigerator's compartments. Alternatively, a pair of double-opening rotating doors can be provided in the first refrigerator compartment 101.

[0066] The frame component 5 is not limited to the example where a pair of longitudinal frames 53, upper frame 51, lower frame 52, and reinforcing member 54 are formed by a single component. The frame component can also be a structure in which all or part of the longitudinal frames, transverse frames, and reinforcing members are formed by different components and then assembled.

[0067] The reinforcing parts are not limited to examples like the reinforcing parts 54 and 54A of drawer doors 30 and 40, which are arranged along the longitudinal direction V. For example, they can also be arranged as follows: Figure 14 as well as Figure 15 As shown in the variant example, it is inclined relative to the longitudinal direction V. In Figure 14 In the modified frame member 5B shown, the reinforcing part 54B is arranged obliquely downward from the upper frame 51. The reinforcing part 54B extends from the upper frame 51 to the lower corner 50B of the connection between the lower end of the longitudinal frame 53 and the two ends of the lower frame 52 in the width direction W. Figure 15 In the modified example shown, the frame member 5C has a reinforcing part 54B mounted at an angle from the upper frame 51 toward the lower frame 52. Thus, even though the reinforcing parts 54B and 54C are mounted at an angle from the upper frame 51 toward the lower, the upper frame 51 can still be supported from below, just like in the embodiment described above.

[0068] The structural examples of thick-walled portions provided in the reinforcing parts 54 and 54A are not limited to the examples described above. Figures 16 to 19 The image shows the horizontal cross-sectional shape of a deformed example of a thick-walled section.

[0069] like Figure 16 As shown, the rear surface 542 of the reinforcing portion 54D can also be formed with its two ends in the width direction W being approximately parallel to the front surface 543, and its central portion protruding rearward into a thick-walled portion 541D. The thick-walled portion 541D has a curved surface shape that protrudes rearward.

[0070] like Figure 17 As shown, the rear surface 542 of the reinforcing portion 54E may also be formed with a pair of thick-walled portions 541E, the central portion of which is approximately parallel to the front surface 543 in the width direction W, and the two ends of which protrude rearward. The pair of thick-walled portions 541E protrude in a direction that is approximately orthogonal to the rear surface 542.

[0071] like Figure 18 As shown, a plurality of thick-walled portions 541F may also be provided separately in the width direction W from the rear surface 542 of the reinforcing portion 54F. The plurality of thick-walled portions 541F are arranged at equal intervals in the width direction W. The plurality of thick-walled portions 541F protrude in a direction substantially orthogonal to the rear surface 542.

[0072] like Figure 19As shown, it can also be formed as a thick-walled portion 541G that protrudes rearward from the center of the rear surface 542 in the width direction W of the reinforcing portion 54G. The thick-walled portion 541G protrudes in a direction that is approximately orthogonal to the rear surface 542.

[0073] Although the illustration is omitted, the structure could also be that the handle 511 is located on the lower frame 52 of the drawer door. When the handle 511 is located on the lower frame 52, the load of the handle 511 is applied to the lower frame 52, making it prone to downward bending. In such a case, by providing the aforementioned reinforcement at the opening 50, bending and warping of the frame component can be prevented.

[0074] The number of reinforcing parts provided on the frame component only needs to be one or more. For example, such as Figure 20 As shown in the frame member 5F, a reinforcing part 54 can also be provided at approximately the center of the width direction W of the opening 50. Alternatively, three or more reinforcing parts can be separately arranged in the width direction W.

[0075] According to the above embodiment, the drawer door 30 is equipped with a reinforcing member 7, thus preventing the longitudinal frame 53 from bending. In the case of drawer doors 30 and 40, when items are stored in the drawer 17, they move along the front-to-back direction D. When opening and closing drawer doors 30 and 40, a downward force is applied to the lower center of the drawer doors 30 and 40, resulting in a load on the frame member 5 of the drawer doors 30 and 40. In contrast, by providing the reinforcing member 7 within the frame member 5, the longitudinal frame 53 is less prone to bending, and the shape of the drawer doors 30 and 40 can be stably maintained. As a result, smooth opening and closing of the drawer doors 30 and 40 is possible.

[0076] According to the embodiment, the frame member 5 has a reinforcing portion 54 mounted on the opening 50, thus improving the strength of the frame member 5. Specifically, the frame member 5 is composed of a pair of longitudinal frames 53, an upper frame 51, and a lower frame 52, with the opening 50 formed in the center when viewed from the front. As a result, the frame member 5 can be made lightweight. A handle 511 is continuously provided on the frame member 5 along with the upper frame 51, and the portion of the handle 511 is thicker than the longitudinal frames 53, the upper frame 51, and the lower frame 52. Therefore, the frame member 5 is prone to bending due to the load on the handle portion. In contrast, by mounting the reinforcing portion 54 on the opening 50, the load-bearing capacity of the frame member 5 in the longitudinal direction V is improved. Therefore, warping, bending, and deformation of the frame member 5 can be prevented. As a result, warping and deformation of the decorative panels 63 and 64 provided on the front surface 57 of the frame member 5 can be prevented. That is, drawer doors 30 and 40 using the frame member 5 can balance aesthetic design with user convenience.

[0077] According to the embodiment, the frame component 5, handle 511, and reinforcing part 54 are integrally formed, thus achieving high manufacturing efficiency. Since the frame component 5, handle 511, and reinforcing part 54 are integrally formed, weight reduction is possible. The reinforcing part 54 prevents warping, deformation, and other distortions of the frame component 5. The handle 511 requires higher strength than the frame body 59. Therefore, the handle 511 is thicker than the vertical frame 53 and the horizontal frames 51 and 52. When the handle 511 is integrally molded with the vertical frame 53 and the horizontal frames 51 and 52 using resin, shrinkage marks sometimes occur during the curing stage of the handle 511 during manufacturing. If shrinkage marks occur, the handle 511 is prone to bending downwards. In contrast, the frame component 5 is provided with the reinforcing part 54, thus preventing warping, bending, and other distortions of the upper frame 51.

[0078] According to the embodiment, the reinforcing portion 54 includes a thick-walled portion 541, thus preventing warping of the reinforcing portion 54 and stably supporting the upper frame 51. As a result, warping, deflection, deformation, etc., of the frame member 5 can be prevented. As a result, the decorative panel 63 provided on the front surface 57 of the frame member 5 can be prevented from shifting relative to the frame member 5. The thick-walled portion 541 protrudes rearward from the rear surface 542 of the reinforcing portion 54, thus not interfering with the mounting position of the flat decorative panel 63 relative to the frame member 5.

[0079] According to the embodiment, the upper end of the thick-walled portion of the reinforcing part is continuously provided at the lower end of the handle, thus supporting the handle from below. As a result, the load of the handle applied to the frame member can be supported by the reinforcing part, thereby strengthening the frame member.

[0080] According to the embodiment, the drawer door uses a refrigerator frame, thus preventing warping, deflection, and deformation. As a result, it prevents the decorative panel from shifting or warping relative to the frame components. Therefore, the aesthetic design of the drawer door can be maintained. In particular, in the case of a frameless drawer door without a decorative frame around the decorative panel, the shift between the decorative panel and the frame components is not significant, and a high degree of aesthetic design can be maintained.

[0081] According to the embodiment, the refrigerator 100 is equipped with the aforementioned drawer door, thus preventing warping, bending, and deformation of the drawer door, which are easily visually identifiable, and maintaining a high degree of aesthetic design. The refrigerator 100, equipped with the aforementioned drawer door, therefore exhibits excellent load-bearing capacity. As a result, the strength of the drawer door is maintained, ensuring smooth pull-out operation. Therefore, user convenience is improved.
