Fig. 1 is a front view of a refrigerator 100 according to an embodiment. Fig. 2 is a side view of the refrigerator doors 20, 30, 40 of the refrigerator 100 viewed from the right side of fig. 1. As shown in fig. 1, the refrigerator 100 includes a refrigerator main body 110 and a plurality of refrigerator doors 20, 30, 40. The refrigerator main body 110 includes a box 105, a known compressor, a cooling mechanism, a blower, a temperature sensor, a control device, and the like, which are not shown.

The casing 105 is provided with a plurality of storage chambers 101, 102, 103. The plurality of storage compartments are, for example, a first refrigerator compartment 101, a second refrigerator compartment 102, and a freezer compartment 103. In the embodiment, first refrigerator compartment 101 is disposed in the uppermost part, second refrigerator compartment 102 is disposed below first refrigerator compartment 101, and freezer compartment 103 is disposed below second refrigerator compartment 102. The arrangement of storage compartments 101, 102, and 103 is not limited to the above example, and the arrangement of second refrigerator compartment 102 and freezer compartment 103 may be reversed, for example. Storage shelves, storage containers, ice-making water storage containers, and the like are appropriately provided in each storage room.

The second refrigerator compartment 102 is used as a vegetable compartment. The second refrigerator compartment 102 is kept cold at a refrigerating temperature band suitable for storage of vegetables, for example, 1 to 5 ℃. Second refrigerating room 102 is not limited to a storage room suitable for the storage environment of vegetables, and may be a storage room having a refrigerating function set to the same refrigerating temperature band as first refrigerating room 101.

The freezing chamber 103 is kept cold in a freezing temperature range, for example, below-10 ℃. Second refrigerating room 102 and freezing room 103 are configured to be able to switch the cooling temperature arbitrarily from the freezing temperature range to the refrigerating temperature range. Therefore, the second refrigerating compartment can be used as a freezing compartment, and the freezing compartment 103 can be used as a refrigerating compartment.

The box 105 includes, for example, an inner box, an outer box, and a heat insulating portion. The inner box forms an inner surface of the housing 105 and the outer box forms an outer surface of the housing 105. A heat insulating part containing a foamed heat insulating material such as foamed polyurethane is provided between the inner box and the outer box. The box 105 has heat insulating properties. The box 105 has an opening on the front surface side of each storage room, through which stored articles can be taken out of or put into each storage room.

The refrigerator 100 is provided with refrigerator doors 20, 30, 40. The refrigerator door is a member that openably closes the openings of the storage chambers 101, 102, and 103. The refrigerator doors 20, 30, 40 are provided at the front of the cabinet 105. The refrigerator doors are, for example, a revolving door 20, a drawer door 30, 40.

The first refrigerating compartment 101 is provided with a revolving door 20. The swing door 20 is rotatably mounted to the cabinet 105. As shown in fig. 2, the swing door 20 includes a frame member 15, a decorative plate 62, and a rear surface member 122. The frame member 15 is a rectangular frame constituting the outer contour of the revolving door 20. A decorative plate 62 is attached to the front surface 57 of the frame member 15. A rear surface member 122 is attached to the rear portion of the frame member 15.

In fig. 1, the single-opening rotary door 20 is illustrated, but a double-opening rotary door may be used. In the case of the swing doors which are opened in two, the left and right swing doors may be the same size, or may be a pair of swing doors different in size in the width direction W.

Drawers 17 (see fig. 2) are disposed in second refrigerating room 102 and freezing room 103, respectively. Drawer 17 constitutes a drawer-type storage portion that is openable and closable in second refrigerating room 102 and freezing room 103 so as to be movable in front-rear direction D. Drawer doors 30, 40 are provided at the front of the drawer 17. The drawer doors 30 and 40 are examples of drawer doors for a refrigerator. The drawer doors 30 and 40 of the second refrigerating compartment 102 and the freezing compartment 103 have the same structure, and therefore, the drawer door 30 of the second refrigerating compartment 102 will be described, and the same reference numerals will be given to the common parts.

Fig. 9 is a longitudinal sectional view of a substantially central portion of the drawer door 30 in the width direction W. Fig. 10 is a horizontal sectional view of the drawer door 30. Fig. 11 is a front view of the frame member 5A of the drawer door 40. As shown in fig. 9 and 10, the drawer doors 30 and 40 include frame members 5 and 5A, decorative panels 63 and 64, and a rear surface material 22. The frame members 5 and 5A are examples of a frame for a refrigerator door. Decorative plates 63, 64 are attached to the front surfaces 57 of the frame members 5, 5A. A rear surface material 22 is attached to the rear of the frame members 5 and 5A. The space between the frame members 5, 5A, the rear surface material 22, and the decorative plate 62 is filled with a foam heat insulating material. The foamed insulation material is also in contact with the rear surface of the decorative panel 62. The fixing state of the decorative plate 62 to the frame members 5 and 5A is stably maintained by the foamed heat insulating material. The foamed heat insulating material is made of, for example, polyurethane.

Fig. 4 is a front view of the frame member 5. Fig. 5 is a perspective view of the frame member 5. The frame part 5 forms the outer contour of the drawer door 30. Fig. 6 is a perspective view of the frame member 5 as viewed from the back side. As shown in fig. 4 to 16, the frame member 5 is a member having a rectangular three-dimensional shape and a thickness in the front-rear direction D when viewed from the front. The frame member 5 includes 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 the frame member 5 are integrally formed. The frame member 5 is a resin or steel plate profile, for example. The frame member 5 is formed with an opening 50 surrounded by a pair of vertical frames 53, an upper horizontal frame 51, and a lower horizontal frame 52. The opening 50 penetrates along the front-rear direction D of the frame member 5.

As shown in fig. 10, the vertical frame 53 includes side walls 531, a front wall 532, and a rear wall 533. The side walls 531 are arranged along the front-rear direction D. The front wall 532 extends inward in the width direction W from the front ends of the side walls 531. The rear wall 533 extends inward in the width direction W from the rear end of the side wall 531. 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 from the outer end of the rear wall 533. The side wall 531 includes a flat surface 531a extending from an end of the rear wall 533 toward the front side, and an inclined surface 531b inclined inward from an intermediate portion in the front-rear direction D toward an outer end of the front wall 532. A recess 4 recessed inward in the width direction W is formed at a connecting portion between the front end of the side wall 531 and the front wall 532. The recess 4 is recessed rearward of the front wall 532 more inward in the width direction W than the outer end 535 of the front wall 532. The horizontal cross-sectional shape of the recess 4 is a circular arc-shaped depression.

As shown in fig. 5, 6, and 9, a handle 511 is formed on the upper frame 51. The handle 511 has a groove shape recessed downward between the middle portion and the front end of the upper frame 51 in the front-rear direction D. As shown in fig. 2 and 3, the handle 511 is formed over the entire width W of the drawer door 30 and opens to the side wall 531. Therefore, the user has good accessibility to the portion holding the drawer door 30. Since both ends of the handle 511 are open on the side walls 531, dust entering the inside of the handle 511 can be easily removed, and cleaning performance is excellent.

The handle 511 has a substantially U-shape in plan view. The handle 511 has a bottom 511a and a pair of vertical surfaces 511b and 511c extending upward from the front and rear ends of the bottom 511a and facing each other, and substantially orthogonal to each other and at an angle of substantially right angle. The boundary between the bottom 511a and the vertical surfaces 511b and 511c forms a small-diameter R-surface. The handle 511 is formed of a linear rectangular concave portion. The handle 511 has a substantially U-shaped side view, and thus the decorative plate 63 of the drawer door 30 has a straight appearance. As shown in fig. 3, the decorative plate 63 and the handle 511 have a unified feeling. Further, since the handles 511 are opened at both ends in the width direction W of the drawer door 30, the user can easily visually recognize the handles.

Since the recess 4 is formed in the side wall 531 of the frame member 5, the decorative plate 63 is separated from the side wall 531 in appearance. As a result, the decorative plate 63 has an appearance of floating from the frame member 5. Therefore, it is difficult to visually confirm the support body supporting the decorative plate 63, and a frameless appearance is obtained. The drawer door 30 obtains a visual effect in appearance that the decorative plate 63 is suspended from the door.

The lower frame 52 is provided continuously between the lower ends of the pair of vertical frames 53.

An adhesive surface 95 of the decorative plate 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.

As shown in fig. 4 to 6, a reinforcing portion 54 is provided across the opening 50 of the frame member 5. The two reinforcing portions 54 are arranged apart in the width direction W. The reinforcement portion 54 spans from the upper frame 51 to the lower frame 52. The reinforcement portion 54 extends along the longitudinal direction V. The reinforcement portion 54 is located on the same surface as the adhesive surface 95 of the decorative plate 63 or behind the adhesive surface 95. In the example shown in fig. 7 and 8, the reinforcing portion 54 is located slightly rearward of the adhesion surface 95. The reinforcing portion 54 supports the upper frame 51 from below.

As shown in fig. 10, the reinforcing portion 54 has a thick portion 541. The thick portion 541 protrudes rearward from the rear surface 542 of the reinforcement portion 54. By providing the reinforcing portion 54 with the thick portion 541, a higher reinforcing effect can be obtained. That is, by providing the thick portion 541 in the reinforcing portion 54, the rigidity of the reinforcing portion 54 increases. As a result, the reinforcing portion 54 can be prevented from being bent in the front-rear direction D. Since thick portion 541 protrudes rearward from rear surface 542 of reinforcing portion 54, attachment of decorative plate 63 to frame member 5 is not hindered.

As shown in fig. 6 and 9, an upper end 544 of the thick portion 541 is provided continuously with the lower surface 511d of the bottom 511a of the handle 511. Since thick portion 541 is provided continuously with lower surface 511d of handle 511, downward load of upper frame 51 can be supported more stably.

The upper end 544 of the thick portion 541 is not necessarily formed continuously with the lower surface 511d of the handle 511. The upper end 544 of the thick portion 541 may be formed separately from the lower surface 511d of the handle 511. If the upper end 544 of the thick portion 541 is separated from the lower surface 511d of the handle 511, for example, in the case of manufacturing the frame member 5 by integral molding of resin, it is possible to prevent sink marks from being generated in the widthwise central portion of the handle 511, which is advantageous in terms of manufacturing.

The reinforcing portion 54 is formed integrally with the frame member 5. The frame main body 59, the handle 511, and the reinforcing portion 54 of the frame member 5 of the present embodiment are integrally formed. The structure in which the reinforcing portion 54 is formed integrally with the frame member 5 is not essential. For example, the frame main body 59 and the reinforcing portion 54 may be formed of different members, and the reinforcing portion 54 may be fixed to the frame main body 59.

A panel support portion 9 is provided at the front portion of the frame member 5. The panel support portion 9 is integrally formed with 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 at the outer edge portions of the front walls 512, 522, 532 of the frame member 5. As shown in fig. 9, the panel support portion 9 is formed to slightly protrude 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. As shown in fig. 10, the panel support portion 9 is formed to slightly protrude forward from the outer end of the front wall 532 in the width direction W of the vertical frame 53.

As shown in fig. 9, a locking claw 94 protruding forward is formed on the panel support portion 9 of the lower frame 52. The amount of forward projection of the locking claw 94 is substantially equal to the thickness of the decorative plate 63. The rear end 634 of the lower side 633 of the decorative plate 62 abuts against the catch 94. The lower side surface 633 is covered with the locking claw 94. The locking claw 94 is provided in a range narrower than the lower side surface 633 of the decorative plate 63 in the width direction W. Thus, the corner portion of the front end in the width direction W of the lower end of the decorative plate 63 is exposed. In the case where an adult stands in front of the refrigerator 100, the lower side 633 is lower than the eyes of the user. Therefore, the locking claw 94 is difficult to be seen by the user. As a result, it appears as a frameless construction with the entire area of the lower side of the decorative panel 63 exposed.

The panel support portion 9 of the upper frame 51 is provided in front of the handle 511. As shown in fig. 9, a locking claw 93 slightly protruding forward from the front wall 512 of the handle 511 is formed on the upper portion of the panel support portion 9. The amount of protrusion of the locking claw 93 toward the front is shorter than the thickness of the decorative plate 63. The rear end 634 of the upper side surface 632 of the decorative plate 63 abuts against the lower portion 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 with the locking claw 93, and the other front side portion is exposed to the outside. The exposed portion of the upper side surface 632 is exposed rearward of the intermediate portion in the front-rear direction D from the front end 635. The locking claw 93 is provided in a range narrower than the upper side surface 632 of the decorative plate 63 in the width direction W. Thus, the corner portion of the front end of the upper end of the decorative plate 63 in the width direction W is exposed. Since the locking claws 93 are slightly exposed only at the rear portion of the decorative plate 63, the entire area of the upper side surface 632 of the decorative plate 63 can be exposed visually.

The lower side surface 633 of the decorative plate 63 of the drawer door 30 is protected by the locking claw 94, and the rear end 634 of the upper side surface 632 is protected by the locking claw 93. As shown in fig. 10, lateral side surfaces 631 at both ends of the decorative plate 63 in the width direction W are exposed. Lateral side surfaces 631 at both ends of the decorative panel 63 in the width direction W are disposed on the same surface as the outer side end 535 of the front wall 532.

As shown in fig. 10, a reinforcing member 7 is provided inside the vertical frame 53. The reinforcing member 7 is a member that reinforces the strength of the frame member 5. The drawer door applies a load when the drawer door is pulled out in a state that the storage part stores the refrigerated goods. Therefore, the reinforcing member 7 is provided to reduce the weight of the drawer door and to reinforce the strength of the frame member 5. The reinforcing member 7 is a metal elongated member such as a steel plate.

A heat insulating material filling portion 58 is formed in a gap between the reinforcing member 7 and the vertical frame 53. The vertical frame 53 has a heat insulator filling hole 73 formed therein. The heat insulator filling holes 73 are formed in plural at intervals in the longitudinal direction V. The heat insulating material is filled into the heat insulating material filling portion 58 through the heat insulating material filling hole 73. The heat insulator is formed by, for example, filling a foamed heat insulator made of polyurethane or the like from the heat insulator filling hole 73 into the heat insulator filling portion 58 and curing the same. By filling the heat insulating material filling portion 58 with the foamed heat insulating material, the heat insulating material is bonded to the vertical frame 53 and the reinforcing member 7, and the frame member 5 is reinforced. Even if the reinforcing member 7 is made of a steel plate, the heat insulating performance of the drawer door 30 can be improved by filling the heat insulating material.

The drawer door 40 of the freezer compartment 103 is shown in fig. 11 to 13. The basic structure of the drawer door 40 is the same as the drawer door 30 of the second refrigerator compartment 102. As shown in fig. 1, the drawer door 40 has a larger area as viewed from the front than the drawer door 30. Therefore, the size of the frame member 5A of the drawer door 40 is larger than the size of the frame member 5 of the drawer door 30. As shown in fig. 11, the frame member 5A further includes a second horizontal frame 56. The upper frame 51, the lower frame 52, the pair of vertical frames 53, the reinforcing portion 54, and the second horizontal frame 56 of the frame member 5A are integrally formed. The reinforcing portion 54A extends from the upper frame 51 to the second lateral frame 56 in the vertical direction V. The reinforcing portion 54A has a larger dimension in the width direction W than the reinforcing portion 54 of the drawer door 30. As shown in fig. 12 and 13, a thick portion 541A, in which the central portion protrudes rearward from both end portions in the width direction W, is formed on the rear surface 542 of the reinforcement portion 54A. The second horizontal frame 56 is an example of a lower horizontal frame. An opening 55 is formed between the second horizontal frame 56, the pair of vertical frames 53, and the lower frame 52. The opening 55 is also provided with a reinforcement. The frame member 5 may be formed of one member, or may be assembled by forming all or a part of the vertical frame, the horizontal frame, the reinforcing portion, and the second horizontal frame from different members.

The drawer doors 30 and 40 are provided with a rear surface material 22 for a drawer at the rear of the frame members 5 and 5A. The rear surface material 22 is attached to substantially the entire rear portion of the frame member 5. The rear surface material 22 is a resin three-dimensional molded member having heat insulation properties. As shown in fig. 9 and 10, the rear surface material 22 has a portion projecting rearward from the frame member 5. The rear surface material 22 can be inserted into an opening of the second refrigerator compartment 102. A gasket 16 is attached to the outer edge portion of the connecting portion between the frame members 5 and 5A and the rear surface material 22, which is the rear surface of the drawer doors 30 and 40. Gasket 16 is configured to close a gap between drawer doors 30 and 40 and an inner wall of second refrigerating compartment 102 in a state where drawer door 30 is closed.

The front surface 57 of the frame member 5 is covered by attaching the decorative plate 63 to the panel support portion 9. The decorative plates 63 and 64 are made of a substantially flat plate-like decorative material. The decorative plates 63 and 64 are thin plates made of glass, fiber-reinforced resin, ceramic, artificial marble, or the like, for example. The decorative plates 63 and 64 are colored, patterned, and finished in consideration of the design of the refrigerator. As an example, a glass decorative plate is shown.

The decorative plates 63 and 64 are fixed to the adhesive surface 95 of the frame member 5 with an adhesive. Outer edge portions of the rear surfaces of the decorative plates 63 and 64 abut against the panel support portion 9. An adhesive is disposed and fixed between the rear surfaces of the decorative plates 63, 64 and the front wall 532. The adhesive is not particularly limited as long as it is an adhesive of a coating type, an adhesive tape, or the like, and can fix the decorative plates 63, 64 to the front surface 57 of the frame member 5.

The side surfaces of the decorative plates 63 and 64 are arranged substantially flush with the outer peripheral end of the front end of the frame member 5. As shown in fig. 10, the lateral side surface 631 of the decorative panel 63 is disposed at the same position as the outer side end 535 of the front wall 532 in the width direction W. The side wall 531 of the frame member 5 does not protrude outward beyond the end in the width direction W of the decorative plate 63. The side wall 531 of the frame member 5 is disposed on the same surface or on the inner side in the width direction W as the lateral side surface 631 of the decorative plate 63. The lateral side surface 631 of the decorative plate 63 is disposed on the same surface or on the outer side in the width direction W as the outer side end 535 of the front wall 532 constituting the panel support portion 9. As shown in fig. 9, the upper side surface 632 of the decorative plate 63 is disposed at substantially the same height as the panel support portion 9 of the upper frame 51.

At least the front end 635 of the lateral side surface 631, the upper side surface 632, and the lower side surface 633 of the decorative plate 63 on both sides in the width direction W is exposed and supported by the frame member 5. That is, the frame member 5 is disposed on the same surface or inside of the lateral side surface 631 and the upper side surface 632 of the decorative plate 62, and the locking claw 94 covers the rear end 634 of the lower side surface 633 of the decorative plate 63. Thus, the user standing in front of the refrigerator 100 can hardly see the frame member 5, and a frameless appearance in which only the decorative plate 63 is exposed can be obtained. As a result, the drawer doors 30 and 40 have excellent design.

In the embodiment, an example in which three refrigerator doors 20, 30, and 40 for the first refrigerator compartment 101, the second refrigerator compartment 102, and the freezer compartment 103 are provided is shown, but the refrigerator mode is not limited thereto. Any number of refrigerator doors can be provided according to the number and size of the storage chambers of the refrigerator. A double-opening pair of rotary doors may be provided in the first refrigerating compartment 101.

The frame member 5 is not limited to the example in which the pair of vertical frames 53, the upper frame 51, the lower frame 52, and the reinforcing portion 54 are formed by one member. The frame members may also be structures assembled by forming all or a portion of the vertical frames, the horizontal frames, and the reinforcing stack from different members.

The reinforcing portions are not limited to the example in which the reinforcing portions are arranged along the longitudinal direction V as in the reinforcing portions 54, 54A of the drawer doors 30, 40. For example, as in the modification shown in fig. 14 and 15, the vertical direction V may be inclined. In frame member 5B of the modification shown in fig. 14, reinforcing portion 54B is disposed so as to be inclined downward from upper frame 51. The reinforcement portion 54B extends from the upper frame 51 to the lower corner portion 50B of the opening 55, which is the connection portion between the lower end of the vertical frame 53 and the both end portions of the lower frame 52 in the width direction W. In a frame member 5C of a modification shown in fig. 15, a reinforcing portion 54B is provided obliquely from an upper frame 51 toward a lower frame 52. As described above, even if the reinforcing portions 54B and 54C are obliquely erected downward from the upper frame 51, the upper frame 51 can be supported from below, as in the above-described embodiment.

The structural example of the thick portion provided in the reinforcing portions 54 and 54A is not limited to the above example. Fig. 16 to 19 show horizontal cross-sectional shapes of modified examples of the thick portion.

As shown in fig. 16, the reinforcing portion 54D may be formed as a thick portion 541D in which both end portions in the width direction W of the rear surface 542 are substantially parallel to the front surface 543 and a central portion protrudes rearward. The thick portion 541D has a curved surface shape protruding rearward.

As shown in fig. 17, the reinforcing portion 54E may be formed as a pair of thick portions 541E in which the center portion in the width direction W of the rear surface 542 is substantially parallel to the front surface 543 and both end portions protrude rearward. The pair of thick portions 541E protrude in a direction substantially perpendicular to the rear surface 542.

As shown in fig. 18, a plurality of thick portions 541F may be provided apart from the rear surface 542 of the reinforcing portion 54F in the width direction W. The plurality of thick portions 541 are arranged at equal intervals in the width direction W. The plurality of thick portions 541F protrude in a direction substantially perpendicular to the rear surface 542.

As shown in fig. 19, the reinforcing portion 54G may be formed as a single thick portion 541G projecting rearward at the center portion in the width direction W of the rear surface 542. One thick portion 541G protrudes in a direction substantially orthogonal to the rear surface 542.

Although not shown, the handle 511 may be provided on the lower frame 52 of the drawer door. When the handle 511 is provided on the lower frame 52, a load of the handle 511 is applied to the lower frame 52, and the lower frame 52 is easily bent downward. In such a case, the reinforcing portion is provided in the opening 50, whereby the frame member can be prevented from being bent or warped.

The number of the reinforcing portions provided in the frame member may be 1 or more. For example, as in the frame member 5F shown in fig. 20, one reinforcing portion 54 may be provided at a substantially central portion in the width direction W of the opening 50. Further, 3 or more reinforcing portions may be disposed apart in the width direction W.

According to the above embodiment, since the drawer door 30 is provided with the reinforcing member 7, the vertical frame 53 can be prevented from being bent. In the case of the drawer doors 30 and 40, the drawer 17 moves in the front-rear direction D in a state where the stored items are stored therein. When the drawer doors 30 and 40 are opened and closed, a downward force is applied to the lower center of the drawer doors 30 and 40, and as a result, a load is applied to the frame member 5 of the drawer doors 30 and 40. In contrast, by providing the reinforcing member 7 in the frame member 5, the vertical frame 53 is less likely to be bent, and the shape of the drawer doors 30 and 40 can be stably maintained. As a result, the drawer doors 30 and 40 can be smoothly opened and closed.

According to the embodiment, since the frame member 5 has the reinforcing portion 54 that is bridged over the opening 50, the strength of the frame member 5 can be improved. That is, the frame member 5 is composed of a pair of vertical frames 53, an upper frame 51, and a lower frame 52, and has an opening 50 formed in the center portion in front view. As a result, the frame member 5 can be reduced in weight. The frame member 5 is provided with a handle 511 continuously extending from the upper frame 51, and the handle 511 is thicker than the vertical frame 53, the upper frame 51, and the lower frame 52. Therefore, the frame member 5 is easily deflected by the load of the handle portion. In contrast, the reinforcing portion 54 is provided across the opening 50, thereby improving the load resistance of the frame member 5 in the longitudinal direction V. Thus, warping, bending, deformation, and the like of the frame member 5 can be prevented. As a result, the decorative plates 63 and 64 provided on the front surface 57 of the frame member 5 can be prevented from warping or deforming. That is, the drawer doors 30 and 40 using the frame member 5 can achieve both the design and the user's convenience.

According to the embodiment, the frame member 5, the handle 511, and the reinforcing portion 54 are integrally formed, and therefore, the manufacturing efficiency is high. Since the frame member 5, the handle 511, and the reinforcement portion 54 are integrally formed, the weight can be reduced. The reinforcing portion 54 can prevent the frame member 5 from warping, deforming, or the like. The handle 511 needs to have higher strength than the frame main 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 by resin, sink marks may be generated at the curing stage of the handle 511 during manufacturing. If sink marks are generated, the handle 511 is easily bent downward. In contrast, since the frame member 5 is provided with the reinforcing portion 54, warping, bending, deformation, and the like of the upper frame 51 can be prevented.

According to the embodiment, since the reinforcing portion 54 includes the thick portion 541, the upper frame 51 can be stably supported by preventing the reinforcing portion 54 from warping. As a result, warping, bending, deformation, and the like of the frame member 5 can be prevented. As a result, the decorative plate 63 provided on the front surface 57 of the frame member 5 can be prevented from being displaced with respect to the frame member 5. Since the thick portion 541 protrudes rearward from the rear surface 542 of the reinforcing portion 54, it does not interfere with the mounting position of the flat decorative plate 63 to the frame member 5.

According to the embodiment, the upper end of the thick portion of the reinforcing portion is continuously provided to the lower end of the handle, and therefore, the handle is supported from below. As a result, the load of the handle applied to the frame member can be supported by the reinforcing portion, and the strength of the frame member can be reinforced.

According to the embodiment, the drawer door uses the refrigerator frame, so that the warping, bending, deformation, and the like of the drawer door can be prevented. As a result, the decorative plate can be prevented from shifting or warping with respect to the frame member. Thus, the design of the drawer door can be maintained. In particular, in the case of a frameless drawer door in which a decorative frame is not provided around a decorative panel, the decorative panel does not significantly deviate from a frame member, and high design can be maintained.

According to the embodiment, since the refrigerator 100 includes the drawer door described above, warping, bending, and deformation of the drawer door, which is easily visually recognized in appearance, can be prevented, and high design properties can be maintained. The refrigerator 100 includes the drawer door described above, and thus has excellent load resistance. As a result, the strength of the drawer door can be maintained, and a smooth drawing operation can be maintained. Thus, user convenience can be improved.

Several embodiments of the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the invention described in the claims and the scope equivalent thereto.
