Figure 1 is a front view showing a refrigerator 100 according to an embodiment. Figure 2 is a side view showing refrigerator doors 20, 30, and 40 of the refrigerator 100 as viewed from the right side of Figure 1. As shown in Figure 1, the refrigerator 100 includes a refrigerator body 110 and a plurality of refrigerator doors 20, 30, and 40. The refrigerator body 110 includes a housing 105 and, although not shown, a known compressor, a cooling mechanism, a blower, a temperature sensor, a control device, etc.

The housing 105 is provided with a plurality of storage compartments 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, the first refrigerator compartment 101 is arranged at the top, the second refrigerator compartment 102 is arranged below the first refrigerator compartment 101, and the freezer compartment 103 is arranged below the second refrigerator compartment 102. The arrangement of the storage compartments 101, 102, 103 is not limited to the above example, and for example, the arrangement of the second refrigerator compartment 102 and the freezer compartment 103 may be reversed. Each storage compartment is appropriately provided with a storage shelf, a storage container, an ice-making water storage container, etc.

The second refrigerator compartment 102 is used as a vegetable compartment. The second refrigerator compartment 102 is kept at a refrigeration temperature range suitable for storing vegetables, for example, 1°C to 5°C. The second refrigerator compartment 102 is not limited to a storage compartment with a storage environment suitable for vegetables, but may be a storage compartment set to the same refrigeration temperature range as the first refrigerator compartment 101 and equipped with a refrigeration function.

The freezer compartment 103 is kept cold at a freezing temperature range, for example, at or below -10°C. The second refrigerator compartment 102 and the freezer compartment 103 are configured so that the cold storage temperature can be switched freely from the freezing temperature range to the refrigeration temperature range. Therefore, the second refrigerator compartment can be used as a freezing compartment, and the freezer compartment 103 can be used as a refrigeration compartment.

The housing 105 has, for example, an inner box, an outer box, and an insulating section. The inner box forms the inner surface of the housing 105, and the outer box forms the outer surface of the housing 105. An insulating section containing a foam insulating material such as urethane foam is provided between the inner box and the outer box. The housing 105 has insulating properties. The housing 105 has an opening on the front side of each storage chamber that allows stored items to be put in and taken out of each storage chamber.

Refrigerator 100 is provided with refrigerator doors 20, 30, and 40. The refrigerator doors are members that close the openings of storage compartments 101, 102, and 103 in an openable and closable manner. Refrigerator doors 20, 30, and 40 are provided at the front of housing 105. The refrigerator doors are, for example, revolving door 20 and drawer doors 30 and 40.

The first refrigerator compartment 101 is provided with a revolving door 20. The revolving door 20 is rotatably attached to the housing 105. As shown in FIG. 2, 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 periphery of the revolving door 20. The decorative panel 62 is attached to the front surface 57 of the frame member 15. The rear surface material 122 is attached to the rear of the frame member 15.

Although FIG. 1 illustrates a single-leaf revolving door 20, a double-leaf revolving door may also be used. In the case of a double-leaf revolving door, the left and right revolving doors may be the same size, or the pair of revolving doors may have different dimensions in the width direction W.

A drawer 17 (see FIG. 2) is provided in each of the second refrigerator compartment 102 and the freezer compartment 103. The drawer 17 constitutes a drawer-type storage section that can be opened and closed to move in the front-rear direction D within the second refrigerator compartment 102 and the freezer compartment 103. Drawer doors 30, 40 are provided at the front of the drawer 17. The drawer doors 30, 40 are an example of a refrigerator drawer door. Since the drawer doors 30, 40 of the second refrigerator compartment 102 and the freezer compartment 103 have the same configuration, they will be described using the drawer door 30 of the second refrigerator compartment 102, and the same reference numerals will be used for common parts.

9 is a vertical cross-sectional view of the drawer door 30 at approximately the center in the width direction W. FIG. 10 is a horizontal cross-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 FIGS. 9 and 10, the drawer door 30, 40 includes the frame member 5, 5A, the decorative panels 63, 64, and the rear surface material 22. The frame member 5, 5A is an example of a refrigerator door frame. The decorative panels 63, 64 are attached to the front surface 57 of the frame member 5, 5A. The rear surface material 22 is attached to the rear part of the frame member 5, 5A. A foam insulation material is filled in the space between the frame member 5, 5A, the rear surface material 22, and the decorative panel 62. The foam insulation material also contacts the rear surface of the decorative panel 62. The fixed state between the decorative panel 62 and the frame member 5, 5A is stably maintained by the foam insulation material. The foam insulation material is made of, for example, urethane.

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

As shown in FIG. 10, the vertical 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 more than the front end. The outer end of the front wall 532 is located inside the width direction W more than the outer end of the rear wall 533. The side wall 531 includes a flat surface 531a extending forward from the end of the rear wall 533 and an inclined surface 531b inclined inward from the middle part 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 in the width direction W. The recess 4 is recessed inward in the width direction W behind the front wall 532 relative to the outer end 535 of the front wall 532. The recess 4 has an arc-shaped horizontal cross section.

As shown in Figures 5, 6 and 9, a handle 511 is formed on the upper frame 51. The handle 511 has a groove shape that is recessed downward between the middle part and the front end of the upper frame 51 in the front-rear direction D. As shown in Figures 2 and 3, the handle 511 is formed over the entire width direction W of the drawer door 30 and opens into the side wall 531. This allows good access to the part where the user grips the drawer door 30. As both ends of the handle 511 open toward the side wall 531, dust that has entered the inside of the handle 511 can be easily removed, making it easy to clean.

The handle 511 has a generally U-shape in side view. The handle 511 has a bottom 511a and a pair of vertical surfaces 511b, 511c that extend upward from the front and rear ends of the bottom 511a and face each other at a generally perpendicular angle and an angle that is close to a right angle. The boundary between the bottom 511a and each vertical surface 511b, 511c is formed with a small radius R surface. The handle 511 is composed of a linear rectangular recess. The generally U-shape in side view of the handle 511 gives the decorative plate 63 of the drawer door 30 a linear appearance. As shown in FIG. 3, the decorative plate 63 and the handle 511 have a sense of unity. In addition, the handle 511 is open at both ends of the width direction W of the drawer door 30, making it easy for the user to see the handle.

Since the recess 4 is formed in the side wall 531 of the frame member 5, the decorative panel 63 appears to be separated from the side wall 531. As a result, the decorative panel 63 appears to be floating away from the frame member 5. Therefore, the support that supports the decorative panel 63 is difficult to see, resulting in a frameless appearance. The drawer door 30 gives the visual effect of the decorative panel 63 floating away 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 four periphery of the front surface 57 of the frame member 5.

As shown in Figures 4 to 6, a reinforcing portion 54 is installed in the opening 50 of the frame member 5. Two reinforcing portions 54 are arranged spaced apart in the width direction W. The reinforcing portions 54 are installed from the upper frame 51 to the lower frame 52. The reinforcing portions 54 extend in the vertical direction V. The reinforcing portions 54 are located on the same plane as the adhesive surface 95 of the decorative panel 63 or behind the adhesive surface 95. In the example shown in Figures 7 and 8, the reinforcing portions 54 are located slightly behind the adhesive surface 95. The reinforcing portions 54 support 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 reinforcing portion 54. By having the thick portion 541 in the reinforcing portion 54, a higher reinforcing effect is obtained. In other words, by having the thick portion 541 in the reinforcing portion 54, the rigidity of the reinforcing portion 54 is increased. As a result, the reinforcing portion 54 is prevented from bending in the front-rear direction D. Because the thick portion 541 protrudes rearward from the rear surface 542 of the reinforcing portion 54, it does not interfere with the attachment of the decorative panel 63 to the frame member 5.

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

It is not essential that the upper end 544 of the thick portion 541 is formed continuously with the lower surface 511d of the handle 511. The upper end 544 of the thick portion 541 and the lower surface 511d of the handle 511 may be formed spaced apart. Spaced apart the upper end 544 of the thick portion 541 and the lower surface 511d of the handle 511, for example, when the frame member 5 is manufactured by integral molding from resin, it is possible to prevent sink marks from occurring in the center of the width direction of the handle 511, which is advantageous in terms of manufacturing.

The reinforcing portion 54 is formed integrally with the frame member 5. In the frame member 5 of this embodiment, the frame body 59, the handle 511, and the reinforcing portion 54 are formed integrally. It is not essential that the reinforcing portion 54 is formed integrally with the frame member 5. For example, the frame body 59 and the reinforcing portion 54 may be formed as separate members, and the reinforcing portion 54 may be fixed to the frame body 59.

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

9, the panel support portion 9 of the lower frame 52 is formed with a locking claw 94 that protrudes forward. The amount of 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 on 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 provided in an area narrower than the lower side surface 633 of the decorative panel 63. Therefore, the corner of the front end 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 eyes. Therefore, the locking claw 94 is difficult for the user to see. As a result, it appears to be a frameless structure in which the entire lower side surface of the decorative panel 63 is 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 is formed on the upper portion of the panel support portion 9, which protrudes slightly forward from the front wall 512 of the handle 511. The amount of forward protrusion of the locking claw 93 is shorter than the thickness of the decorative board 63. The rear end 634 of the upper side surface 632 of the decorative board 63 abuts 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, and the other front part is exposed to the outside. The exposed part of the upper side surface 632 is exposed from the front end 635 to the rear of the middle part in the front-rear direction D. In the width direction W, the locking claw 93 is provided in a range narrower than the upper side surface 632 of the decorative board 63. Therefore, the corner of the front end of the upper end of the decorative board 63 in the width direction W is exposed. The locking claw 93 is only slightly exposed at the rear of the decorative plate 63, creating the visual effect of the entire upper side surface 632 of the decorative plate 63 being exposed.

The lower side surface 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 surface 632 is protected by a locking claw 93. As shown in FIG. 10, the lateral side surfaces 631 at both ends of the width direction W of the decorative panel 63 are exposed. The lateral side surfaces 631 at both ends of the width direction W of the decorative panel 63 are arranged on the same plane as the outer end portion 535 of the front wall 532.

As shown in FIG. 10, a reinforcing member 7 is provided on the inside of the vertical frame 53. The reinforcing member 7 is a member that reinforces the strength of the frame member 5. A load is applied to the drawer door when it is pulled out with refrigerated goods stored in the storage section. Therefore, the reinforcing member 7 is provided to reinforce the strength of the frame member 5 while reducing the weight of the drawer door. The reinforcing member 7 is, for example, a long member made of metal such as a steel plate.

The insulation material filling section 58 is formed in the gap between the reinforcing member 7 and the vertical frame 53. The vertical frame 53 is formed with insulation material filling holes 73. The insulation material filling holes 73 are formed at intervals in the vertical direction V. The insulation material is filled into the insulation material filling section 58 through the insulation material filling holes 73. The insulation material is, for example, a foam insulation material made of urethane or the like, which is filled into the insulation material filling section 58 through the insulation material filling holes 73 and solidified. By filling the insulation material filling section 58 with the foam insulation material, the insulation material is bonded to the vertical frame 53 and the reinforcing member 7, reinforcing the frame member 5. Even if the reinforcing member 7 is made of steel plate, the insulation performance of the drawer door 30 can be improved by filling it with insulation material.

Figures 11 to 13 show the drawer door 40 of the freezer compartment 103. The basic configuration of the drawer door 40 is the same as that of the drawer door 30 of the second refrigerator compartment 102. As shown in Figure 1, the drawer door 40 has a larger area in a front view than the drawer door 30. Therefore, the size of the frame member 5A of the drawer door 40 is larger than the frame member 5 of the drawer door 30. As shown in Figure 11, the frame member 5A further includes a second horizontal frame 56. The frame member 5A is integrally formed with an upper frame 51, a lower frame 52, a pair of vertical frames 53, a reinforcing portion 54, and a second horizontal frame 56. The reinforcing portion 54A is installed in the vertical direction V from the upper frame 51 to the second horizontal frame 56. 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 Figures 12 and 13, the rear surface 542 of the reinforcing portion 54A has a thick portion 541A whose central portion protrudes rearward more than 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, the pair of vertical frames 53, and the lower frame 52. A reinforcing portion may also be provided in the opening 55. The frame member 5 may be configured as a single member, or may be configured such that all or part of the vertical frame, horizontal frame, reinforcing portion, and second horizontal frame are formed as separate members and assembled.

The drawer doors 30, 40 are provided with a rear surface material 22 for the drawer at the rear of the frame members 5, 5A. The rear surface material 22 is a member attached to almost the entire rear of the frame member 5. The rear surface material 22 is a three-dimensional molded member made of resin with thermal insulation properties. As shown in Figures 9 and 10, 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 attached to the outer edge of the rear surface of the drawer doors 30, 40, which is the connection portion between the frame members 5, 5A and the rear surface material 22. The gasket 16 is configured to close 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.

The decorative plate 63 is attached to the panel support portion 9, thereby covering the front surface 57 of the frame member 5. The decorative plates 63, 64 are made of a substantially flat decorative material. The decorative plates 63, 64 are thin plates made of, for example, glass, fiber-reinforced resin, ceramic, artificial marble, or the like. The decorative plates 63, 64 are given a color, pattern, and surface treatment in consideration of the design of the refrigerator. As an example, a glass decorative plate is shown below.

The decorative panels 63, 64 are fixed to the adhesive surface 95 of the frame member 5 with an adhesive. The outer edge of the rear surface of the decorative panels 63, 64 abuts against the panel support portion 9. An adhesive is disposed between the rear surface of the decorative panels 63, 64 and the front wall 532 to fix them. The adhesive is not particularly limited as long as it is an adhesive that can be applied with adhesive, adhesive tape, or the like, and is capable of fixing the decorative panels 63, 64 to the front surface 57 of the frame member 5.

The side surfaces of the decorative panels 63 and 64 are arranged in approximately the same plane as the outer peripheral edge of the front end of the frame member 5. As shown in FIG. 10, in the width direction W, the lateral side surface 631 of the decorative panel 63 and the outer end portion 535 of the front wall 532 are arranged in the same position. The side wall 531 of the frame member 5 does not protrude outward beyond the end portion of the decorative panel 63 in the width direction W. The side wall 531 of the frame member 5 is arranged in the same plane as the lateral side surface 631 of the decorative panel 63 or on the inside in the width direction W. The lateral side surface 631 of the decorative panel 63 is arranged in the same plane as the outer end portion 535 of the front wall 532 that constitutes the panel support portion 9 or outward in the width direction W. As shown in FIG. 9, the upper side surface 632 of the decorative panel 63 is arranged at approximately the same height as the panel support portion 9 of the upper frame 51.

At least the front ends 635 of the lateral side surfaces 631, upper side surfaces 632, and lower side surfaces 633 on both sides of the width direction W of the decorative panel 63 are exposed and supported by the frame member 5. That is, the frame member 5 is disposed on the same plane as or inside the lateral side surfaces 631 and upper side surfaces 632 of the decorative panel 62, and the locking claws 94 cover the rear ends 634 of the lower side surfaces 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 is obtained with only the decorative panel 63 exposed. As a result, the design of the drawer doors 30, 40 is excellent.

In the embodiment, an example is shown in which three refrigerator doors 20, 30, 40 are provided for the first refrigerator compartment 101, the second refrigerator compartment 102, and the freezer compartment 103, but the refrigerator is not limited to this. Any number of refrigerator doors may be provided depending on the number and size of the storage compartments of the refrigerator. The first refrigerator compartment 101 may be provided with a pair of revolving doors that open both ways.

The frame member 5 is not limited to an example in which the pair of vertical frames 53, the upper frame 51, the lower frame 52, and the reinforcing portion 54 are made of a single member. The frame member may be configured such that all or part of the vertical frames, horizontal frames, and reinforcing bars are formed of separate members and then assembled.

The reinforcing portion is not limited to the example arranged along the vertical direction V, as in the reinforcing portion 54, 54A of the drawer door 30, 40. For example, as in the modified example shown in FIG. 14 and FIG. 15, it may be arranged at an angle with respect to the vertical direction V. In the modified frame member 5B shown in FIG. 14, the reinforcing portion 54B is arranged diagonally downward from the upper frame 51. The reinforcing portion 54B is installed 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 both ends of the width direction W of the lower frame 52. In the modified frame member 5C shown in FIG. 15, the reinforcing portion 54B is installed diagonally from the upper frame 51 to the lower frame 52. In this way, even if the reinforcing portions 54B, 54C are installed diagonally downward from the upper frame 51, the upper frame 51 can be supported from below, as in the above embodiment.

The configuration of the thick portion provided in the reinforcing portion 54, 54A is not limited to the above-mentioned example. Figures 16 to 19 show horizontal cross-sectional shapes of modified examples of the thick portion.

As shown in FIG. 16, both ends of the rear surface 542 of the reinforcing portion 54D in the width direction W are approximately parallel to the front surface 543, and the center portion may protrude rearward to form a thick portion 541D. The thick portion 541D has a curved shape that protrudes rearward.

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

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

As shown in FIG. 19, a thick portion 541F protruding rearward may be formed in the center of the width direction W of the rear surface 542 of the reinforcing portion 54G. The thick portion 541F protrudes in a direction substantially perpendicular to the rear surface 542.

Although not shown in the figures, the handle 511 may be provided on the bottom frame 52 of the drawer door. If the handle 511 is provided on the bottom frame 52, the weight of the handle 511 is applied to the bottom frame 52, which is likely to bend downward. Even in such a case, bending or warping of the frame member can be prevented by installing the reinforcing portion described above across the opening 50.

The number of reinforcing parts provided in the frame member may be one or more. For example, as in the frame member 5F shown in FIG. 20, one reinforcing part 54 may be provided in the approximate center of the width direction W of the opening 50. Alternatively, three or more reinforcing parts may be arranged spaced 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 bending. In the case of the drawer doors 30, 40, the drawer 17 moves in the front-rear direction D with items stored inside. When the drawer doors 30, 40 are opened or closed, a downward force is applied to the center of the lower part of the drawer door 30, 40, and as a result, a load is applied to the frame member 5 of the drawer door 30, 40. In contrast, since the reinforcing member 7 is provided inside the frame member 5, the vertical frame 53 is less likely to bend, and the shape of the drawer door 30, 40 is stably maintained. As a result, the drawer doors 30, 40 can be opened and closed smoothly.

According to the embodiment, the frame member 5 has a reinforcing portion 54 that spans the opening 50, and therefore 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 an opening 50 is formed in the center when viewed from the front. As a result, the frame member 5 is made lighter. The frame member 5 has a handle 511 that is continuous with the upper frame 51, and the handle 511 portion is thicker than the vertical frame 53, the upper frame 51, and the lower frame 52. Therefore, the frame member 5 is prone to bending due to the load of the handle portion. In contrast, the reinforcing portion 54 spans the opening 50, and therefore the load resistance of the frame member 5 in the vertical direction V is improved. Therefore, warping, bending, deformation, etc. of the frame member 5 can be prevented. As a result, warping and distortion of the decorative panels 63, 64 provided on the front surface 57 of the frame member 5 can be prevented. In other words, the drawer doors 30, 40 using the frame member 5 can achieve both design and user convenience.

According to the embodiment, the frame member 5, the handle 511, and the reinforcing portion 54 are integrally formed, so that manufacturing efficiency is high. Since the frame member 5, the handle 511, and the reinforcing portion 54 are integrally formed, weight reduction can be achieved. The reinforcing portion 54 can prevent the frame member 5 from warping, warping, deformation, etc. The handle 511 needs to be stronger than the frame body 59. For this reason, the handle 511 is thicker than the vertical frame 53 and the horizontal frames 51 and 52. If the handle 511, the vertical frame 53, and the horizontal frames 51 and 52 are integrally molded from resin, sink marks may occur during the hardening stage of the handle 511 during manufacturing. If sink marks occur, the handle 511 is likely to bend downward. In contrast, the frame member 5 has the reinforcing portion 54, so that warping, bending, deformation, etc. of the upper frame 51 can be prevented.

According to the embodiment, the reinforcement portion 54 includes the thick portion 541, which prevents the reinforcement portion 54 from warping and stably supports the upper frame 51. As a result, the frame member 5 can be prevented from warping, bending, deformation, etc. As a result, the decorative plate 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 portion 541 protrudes rearward from the rear surface 542 of the reinforcement portion 54, so it does not interfere with the mounting position of the flat decorative plate 63 relative to the frame member 5.

According to the embodiment, the upper end of the thick part of the reinforcing part is connected to the lower end of the handle, so that the handle is supported from below. As a result, the load of the handle acting on the frame member is supported by the reinforcing part, and the strength of the frame member can be reinforced.

According to the embodiment, the drawer door uses a refrigerator frame, so warping, flexing, deformation, etc. of the drawer door can be prevented. As a result, misalignment and warping of the decorative panel relative to the frame member can be prevented. Therefore, the external design of the drawer door is maintained. In particular, in the case of a frameless drawer door in which no decorative frame is provided around the decorative panel, misalignment between the decorative panel and the frame member is not noticeable, and high design quality can be maintained.

According to the embodiment, the refrigerator 100 is provided with the above-mentioned drawer door, and therefore warping, bending, and deformation of the drawer door, which are easily visible from the outside, are prevented, and high design quality can be maintained. The refrigerator 100 is provided with the above-mentioned drawer door, and therefore has excellent load-bearing capacity. As a result, the strength of the drawer door is maintained, and smooth drawer operation is maintained. Therefore, convenience for the user can be improved.
