[0088] A foaming space is formed between the outer surface (31) of the door (30) and the inner surface (32) of the door (30), so that the door insulation (35) can be foamed. The door insulation (35) can prevent heat exchange between the outer surface (31) and the inner surface (32) of the door (30). The door insulation (35) can improve the insulation performance between the inside of the storage compartment (20) and the outside of the door (30).

[0089] As the door insulation (35), urethane foam insulation, expanded polystyrene insulation, vacuum insulation panel, etc. can be used. However, the present invention is not limited thereto, and the door insulation (35) can be composed of various materials.

[0090] A refrigerator (1) may include a shelf (70) on which food is placed. The shelf (70) may be provided in a storage compartment (20). In the drawing, the shelf (70) is shown to be provided only in the first storage compartment (21), but this is not limited thereto, and the shelf (70) may also be provided in the second storage compartment (22).

[0091] The shelf (70) can be detachably attached to the inner case (11). In other words, the shelf (70) can be detachably mounted on the first bead (100) described later. Through this configuration, the user can adjust the storage space by attaching the shelf (70) to a desired location.

[0092] A plurality of shelves (70) may be provided. The plurality of shelves (70) may be arranged vertically so as to be spaced apart from each other.

[0093] The refrigerator (1) may include a tray (81) forming a storage space. The tray (81) may be detachably connected to a shelf (70). For example, general food or bottles such as wine (W) may be stored on the tray (81).

[0094] The refrigerator (1) may include a tray coupling portion (82). The tray coupling portion (82) may be coupled to each of a shelf (70) and a tray (81), thereby coupling the tray (81) to the shelf (70). More specifically, the tray coupling portion (82) may be detachably coupled to the shelf (70), thereby coupling the tray (81) to the shelf (70) in a detachable manner. Through this configuration, a user may adjust the storage space by coupling the tray (81) to a desired shelf (70).

[0095] The tray (81) can be slidably connected to the tray coupling portion (82). That is, the tray (81) can be pulled out or inserted into the shelf (70). In other words, the tray (81) can be pulled out from the storage compartment (20) or inserted into the storage compartment (20). Through this configuration, a user can pull the tray (81) out of the storage compartment (20) to store or take out food, and can insert the tray (81) into the storage compartment (20) to store food in the storage compartment (20).

[0096] When the tray (81) is pulled out from the storage room (20), the tray (81) may receive a downward force due to the load of the food stored in the tray (81) or an external force from the user. At this time, the tray (81) is connected to the shelf (70), and since the tray (81) is pulled out from the storage room (20), the front end of the shelf (70) may also receive a downward force. When a downward force is applied to the front end of the shelf (70), the shelf (70) may come off from the first bead (100) described later and be separated from the inner case (11), and as a result, the food stored in the shelf (70) and the tray (81) may spill forward, causing unexpected damage to the user.

[0097] According to the concept of the present disclosure, the refrigerator (1) can more effectively prevent the shelf (70) from coming off the first bead (100). More details regarding this will be described later.

[0098] The configuration of the refrigerator (1) described above with reference to FIGS. 1 to 4 is merely an example for explaining a refrigerator according to the concept of the present disclosure, and the concept of the present disclosure is not limited thereto. A refrigerator according to the concept of the present disclosure may be provided to include various configurations for performing the function of supplying cold air to a refrigerating chamber and a freezing chamber for storing food.

[0103] The first trim (72) may include a lower protrusion (722) extending downward from the lower surface (721b) of the shelf body insert (721). The lower protrusion (722) may extend perpendicularly to the lower surface of the shelf body insert (721).

[0104] The refrigerator (1) may include a first bead (100) configured to support a shelf (70). Specifically, the shelf (70) may be detachably mounted on the first bead (100), and when the shelf (70) is mounted on the first bead (100), the first bead (100) may support the shelf (70).

[0105] The first bead (100) may be provided on the inner case (11). Specifically, the first bead (100) may be provided so as to protrude from the inner wall of the inner case (11). The first bead (100) may extend in the front-rear direction. When the shelf (70) is mounted on the first bead (100), the first bead (100) may be provided below the shelf (70).

[0106] The first bead (100) may be provided in multiple pieces. The plurality of first beads (100) may be arranged in a vertical direction along the inner wall of the inner case (11). In addition, the plurality of first beads (100) may be provided on both inner walls of the inner case (11). Any one first bead (100) provided on one inner wall of the inner case (11) may be provided in pairs with another first bead (100) provided on the other inner wall of the inner case (11) and having the same height. That is, multiple pairs of first beads (100) may be provided on both inner walls of the inner case (11). Any one shelf (70) may be placed on any one pair of first beads (100).

[0107] The refrigerator (1) may include a second bead (200) provided to limit movement of the shelf (70). Specifically, when the shelf (70) is mounted on the first bead (100), the second bead (200) may limit movement of the shelf (70) in the forward / backward direction (X-axis direction) and the upward / downward direction (Z-axis direction).

[0108] The second bead (200) may be provided on the inner case (11). Specifically, the second bead (200) may be provided so as to protrude from the inner wall of the inner case (11). The second bead (200) may be provided on the rear side of the first storage chamber (21). A portion of the second bead (200) may be provided on the rear side of the first bead (100).

[0109] The second beads (200) may be provided in multiple numbers. The plurality of second beads (200) may be arranged in a vertical direction along the inner wall of the inner case (11). In addition, the plurality of second beads (200) may be provided on both inner walls of the inner case (11). Any one of the second beads (200) provided on one inner wall of the inner case (11) may be provided as a pair with another second bead (200) provided on the other inner wall of the inner case (11) and having the same height. That is, multiple pairs of second beads (200) may be provided on both inner walls of the inner case (11). Each of the plurality of second beads (200) may be arranged at a position corresponding to each of the plurality of first beads (100).

[0110] The second bead (200) may include a stopper portion (210). The stopper portion (210) may extend approximately perpendicularly to the first bead (100). In other words, the stopper portion (210) may extend approximately in the vertical direction (Z-axis direction).

[0111] The stopper portion (210) may be provided at the rear of the first bead (100). The stopper portion (210) may be arranged to be spaced apart from the first bead (100). That is, a spaced apart space (210a) may be formed between the stopper portion (210) and the first bead (100). When the shelf (70) is mounted on the first bead (100), a part of the first trim (72) may be arranged in the spaced apart space (210a). Specifically, when the shelf (70) is mounted on the first bead (100), the lower part of the first trim (72) may be arranged in the spaced apart space (210a). In other words, when the shelf (70) is mounted on the first bead (100), the lower part of the shelf body insertion portion (721) and the lower protrusion (722) may be arranged in the spaced apart space (210a).

[0112] When the shelf (70) is mounted on the first bead (100), the stopper portion (210) can limit the backward movement of the first trim (72). When the shelf (70) is mounted on the first bead (100), the forward movement of the first trim (72) can be limited by the first bead (100), and the backward movement of the first trim (72) can be limited by the stopper portion (210) of the second bead (200). Through this configuration, when the shelf (70) is mounted on the first bead (100), the forward and backward movement of the shelf (70) can be limited.

[0113] The second bead (200) may include an anti-lifting portion (220). The anti-lifting portion (220) may extend forward from the stopper portion (210). Specifically, the anti-lifting portion (220) may extend forward from the top of the stopper portion (210).

[0114] The lifting prevention unit (220) may be provided on the upper side of the first bead (100). Specifically, the lifting prevention unit (220) may be provided on the upper side of the rear end of the first bead (100). In other words, when the shelf (70) is mounted on the first bead (100), the lifting prevention unit (220) may be provided on the rear end (71b) of the shelf body (71).

[0115] The anti-lifting member (220) can prevent the rear end of the shelf (70) from lifting upward. In other words, the anti-lifting member (220) can prevent the first trim (72) from lifting upward. In other words, the anti-lifting member (220) can limit the distance by which the first trim (72) can move upward within a predetermined range. This will be discussed in detail below.

[0116] The anti-slip portion (220) may include an extension portion (221) extending in one direction. Specifically, the extension portion (221) may extend parallel to the first bead (100). In other words, the extension portion (221) may extend approximately in the front-back direction (X-axis direction).

[0117] The anti-slip portion (220) may include a protrusion (222) protruding from the extension portion (221). The protrusion (222) may protrude toward the separation space (210a). In other words, when the shelf (70) is mounted on the first bead (100), the protrusion (222) may protrude toward the rear end of the shelf (70). In other words, when the shelf (70) is mounted on the first bead (100), the protrusion (222) may protrude toward the first trim (72).

[0118] The protrusion (222) may be positioned above the space (210a). In other words, when the shelf (70) is mounted on the first bead (100), the protrusion (222) may be positioned above the first trim (72). Specifically, when the shelf (70) is mounted on the first bead (100), the protrusion (222) may be positioned above the shelf body insert (721) of the first trim (72).

[0119] The protrusion (222) may be connected to the stopper portion (210). That is, the protrusion (222) may be simultaneously connected to the stopper portion (210) and the extension portion (221). Accordingly, the protrusion (222) may be defined as a configuration that protrudes from the stopper portion (210). In addition, the protrusion (222) may be defined as a configuration that protrudes between the stopper portion (210) and the extension portion (221).

[0120] The distance (W2) at which the protrusion (222) is spaced apart from the first bead (100) in the vertical direction may be smaller than the vertical width (W1) of the first trim (72). In other words, the distance (W2) at which the protrusion (222) is spaced apart from the first bead (100) in the vertical direction may be smaller than the distance (W1) at which the upper surface (721a) of the shelf body insertion portion (721) is spaced apart from the lower end (722a) of the lower protrusion (722) in the vertical direction. In this case, the distance (W2) at which the protrusion (222) is spaced apart from the first bead (100) in the vertical direction may refer to the distance (W2) from a point between the first inclined surface (222a) and the second inclined surface (222b) described below to the upper surface of the first bead (100). Through this configuration, the distance that the first trim (72) can move upward can be limited within a predetermined range. Specifically, the distance that the first trim (72) can move upward can be smaller than the width (W1) of the first trim (72).

[0121] As described above, when a force is applied downward to the front end of the shelf (70), the shelf (70) can be separated from the inner case (11) by being detached from the first bead (100) to be described later. Specifically, when a force is applied downward to the front end of the shelf (70), the first trim (72) provided at the rear end of the shelf (70) is lifted upward, and when the first trim (72) is completely detached from the separation space (210a), the restriction on the forward and backward movement of the first trim (72) by the first and second beads (100, 200) disappears, and the shelf (70) can be separated from the inner case (11).

[0122] According to the concept of the present disclosure, the lifting prevention unit (220) can limit the distance that the first trim (72) can move upward within a predetermined range through the protrusion (222). Accordingly, the lifting prevention unit (220) can prevent the first trim (72) from being completely separated from the separation space (210a) even when a downward force is applied to the front end of the shelf (70). For example, the lifting prevention unit (220) can prevent the lower portion of the first trim (72) from being separated from the separation space (210a). For example, the lifting prevention unit (220) can prevent the lower protrusion (722) from being separated from the separation space (210a).

[0123] That is, the refrigerator (1) according to the present disclosure can prevent the shelf (70) from coming off the first bead (100). Accordingly, the safety of using the refrigerator (1) can be improved.

[0124] The front surface of the protrusion (222) may include a first inclined surface (222a) inclined toward the extension (221). The first inclined surface (222a) may be inclined upward. The first inclined surface (222a) may be connected to the extension (221). For example, the angle (X1) at which the first inclined surface (222a) is inclined with respect to the extension (221) may be 20 degrees or more and 40 degrees or less. However, the present invention is not limited thereto.

[0125] As described above, the distance (W2) at which the protrusion (222) is spaced apart from the first bead (100) in the vertical direction may be smaller than the vertical width (W1) of the first trim (72). Therefore, in order to mount the shelf (70) on the first bead (100), when inserting the rear end of the shelf (70) between the first bead (100) and the second bead (200) in a direction parallel to the first bead (100) (X-axis direction), the entry of the shelf (70) may be blocked by the protrusion (222).

[0126] According to the concept of the present disclosure, the first inclined surface (222a) of the protrusion (222) can facilitate the process of mounting the shelf (70) on the first bead (100). Referring to FIG. 8, when mounting the shelf (70) on the first bead (100), by inserting the rear end of the shelf (70) between the first bead (100) and the second bead (200) while tilting the shelf (70) in the direction in which the first inclined surface (222a) is inclined, the entry of the shelf (70) can be prevented from being blocked by the protrusion (222).

[0127] The lower surface of the protrusion (222) may include a second inclined surface (222b) inclined toward the stopper portion (210). The second inclined surface (222b) may be inclined toward the rear. The second inclined surface (222b) may be connected to the stopper portion (210).

[0128] Since the front of the protrusion (222) includes an upwardly inclined first inclined surface (222a), the protrusion (222) may have a shape in which the width in the vertical direction becomes smaller as it goes forward. At this time, the angle (X1) at which the first inclined surface (222a) is inclined with respect to the extension (221) may be greater than the angle (X2) at which the second inclined surface (222b) is inclined with respect to the extension (221). Like the first inclined surface (222a), the second inclined surface (222b) can also facilitate the process of mounting the shelf (70) on the first bead (100).

[0129] FIG. 9 is an enlarged view of the rear end of the shelf, the trim, and the second bead according to one embodiment.

[0130] Hereinafter, a second bead (2000) according to one embodiment of the present disclosure will be described with reference to FIG. 9.

The protrusion portion (2220) may be arranged to be spaced apart from the stopper portion (210). Even in this case, since the distance (W2) at which the protrusion portion (2220) is spaced apart from the first bead (100) in the vertical direction is smaller than the width (W1) of the first trim (72) in the vertical direction, the distance at which the first trim (72) can move upward is limited within a predetermined range, thereby preventing the shelf (70) from coming off the first bead (100).

[0132] A refrigerator (1) according to one embodiment includes a main body (10) including an inner case (11) in which a storage compartment (21) is formed and an outer case (12) coupled to the outside of the inner case (11), a shelf (70) provided in the storage compartment (21) and including a shelf body (71) and a trim (72) coupled to a rear end (71b) of the shelf body (71), a first bead (100) provided in the inner case (11) to support the shelf (70), and a second bead (200, 2000) provided in the inner case (11).
