[0112] like Fig. 9 and Fig.10As shown, the shelf base 300 may include a pair of interference ribs 305 formed on the front surface 302 and protruding forward (eg, +X direction). The shelf base 300 may further include a rear rib 360 formed on the rear surface 310f.

[0113] The shelf base 300 may include a guide extension 327 provided on the rear portion of the guide wall 303. The guide extension 327 may guide movement of a guide protrusion 428 of the cold air control lever 400, which will be described later.

[0114] Fig.11 is an exploded perspective view of a cold air control lever according to an embodiment of the present disclosure. Fig.12 and Fig.13 is a bottom perspective view of a cold air control rod with its length adjusted according to an embodiment of the present disclosure.

[0115] refer to Figures 11 to 13 The cold air control lever 400 may include a first cold air control lever 410 including a switch 401 and a second cold air control lever 440 , which is disposed behind the first cold air control lever 410 and includes an opening and closing portion 460 .

[0116] The first cool air control lever 410 may move in a horizontal direction (eg, Y direction) by movement of the switch 401 , and the second cool air control lever 440 may move according to movement of the first cool air control lever 410 moving in the horizontal direction.

[0117] The first cool air control lever 410 may include a guide plate 420 connected to the switch 401 , a seating portion 427 provided at the rear of the guide plate 420 , and a connection portion 430 bent from the seating portion 427 and extending rearward.

[0118] The guide plate 420 may include a pair of elastic protrusions 425 disposed on opposite sides. The seating portion 427 may be seated on the guide wall 303 of the shelf base 300 (see Figure 8 ). The connection part 430 may be a portion supported by the base surface 310 d of the shelf base 300 and coupled to the second cold air control lever 440 .

[0119] The first cold air control bar 410 may include a guide 435 that protrudes from the connection portion 430 in a moving direction (e.g., Y direction) of the first cold air control bar 410. The first cold air control bar 410 may include a guide protrusion 428 disposed between the guide 435 and the seating portion 427. The guide protrusion 428 may guide the movement of the first cold air control bar 410 in a horizontal direction by protruding from a bottom surface of the first cold air control bar 410 toward the shelf base 300, so that a front surface of the guide protrusion 428 comes into contact with the guide extension 327 of the shelf base 300.

[0120] The second cold air control lever 440 may include an insertion hole 450a into which the connection portion 430 of the first cold air control lever 410 is inserted. The second cold air control lever 440 may include a coupling portion 450, a horizontal connection plate 457 disposed at the rear of the coupling portion 450, and a vertical connection plate 458 vertically connected to the horizontal connection plate 457. The vertical connection plate 458 may vertically extend to the horizontal connection plate 457 to support the opening and closing portion 460.

[0121] like Fig.12 and Fig.13 As shown, when the first cold air control bar 410 is inserted into the coupling portion 450 through the insertion hole 450a, the length of the cold air control bar 400 can be adjusted in the front-rear direction (e.g., X direction). In order to adjust the length in the front-rear direction (e.g., X direction), the connecting portion 430 and the coupling portion 450 are not coupled by a coupling member such as a screw, but the connecting portion 430 is supported by a support 455. With this structure, the cold air control bar 400 can be provided on a shelf of the refrigerator 1 having various shapes, thereby increasing practicality.

[0122] Fig.14 is a perspective view of a cold air control lever disposed on a shelf base and in a first position according to an embodiment of the present disclosure. Fig.15 is a perspective view of a cold air control lever disposed on a shelf base and in a second position according to an embodiment of the present disclosure. Fig.16 is a bottom perspective view of a cold air control lever coupled to a shelf body and located in a first position according to an embodiment of the present disclosure. Fig.17 is a bottom perspective view of a cold air control lever coupled to a shelf body and located in a second position according to an embodiment of the present disclosure.

[0123] The cold air control lever 400 is movable between the first position P1 and the second position P2 by being seated on the shelf base 300, and is moved between the first position P1 and the second position P2 by making contact with the shelf body 200, which movement will be referred to below. Figures 14 to 17Described in detail.

[0124] When the cold air control lever 400 is in the first position P1, the second cold air control lever 440 may be in the open position OP, and the coupling portion 450 may come into contact with the right side of the first stopper 350a. Since the plurality of first stoppers 350a protrude from the base surface 310d and are arranged in the front-rear direction (e.g., the X direction), the cold air control lever 400 may be prevented from moving to the left side (e.g., the -Y direction) of the first stopper 350a.

[0125] The cold air control lever 400 can slide to the second position P2 according to the movement of the switch 401 in the horizontal direction. At this time, the second cold air control lever 440 can be located at the closed position CP. When the second cold air control lever 440 is located at the closed position CP, the coupling portion 450 can interfere with the left side of the second stopper 350b. Since the structure of the first stopper 350a is also applied to the second stopper 350b as described above, the cold air control lever 400 can be prevented from moving in the second position P2.

[0126] With this structure, unlike the structure in which the cold air control bar 400 interferes with the front opening 201 of the shelf body 200 , the rear portion of the cold air control bar 400 may slide only between the first position P1 and the second position P2 by interfering with the stopper 350 .

[0127] In addition, since the seating portion 427 of the cold air control bar 400 may move in a horizontal direction along the guide wall 303 of the shelf base 300 , movement of the first cold air control bar 410 may be guided.

[0128] Since one surface of the guide protrusion 428 of the cold air control bar 400 may move in a horizontal direction while making contact with the guide extension 327 of the shelf base 300 , movement of the first cold air control bar 410 may be guided.

[0129] The cool air control bar 400 positioned below the shelf body 200 may be guided by the guide ribs 235 provided on the bottom surface 210 d of the shelf body 200 to move in the horizontal direction between the first position P1 and the second position P2 .

[0130] More specifically, the cold air control lever 400 may include a guide 435 extending from the connection portion 430 (see FIG. 4 ) in the moving direction of the first cold air control lever 410. Fig.11) extends. The guide ribs 235 may be spaced apart by the width of the guide member 435 so as to make contact with the front and rear ends of the guide member 435. In order to have such a structure, the guide ribs 235 may be provided as a pair spaced apart in the front-to-rear direction. The guide ribs 235 may extend in the horizontal direction along the longitudinal direction (e.g., the Y direction) of the front opening 201 of the shelf body 200, and may be provided to be longer than the length between the left end of the guide member 435 of the cold air control bar 400 located at the first position P1 and the right end of the guide member 435 of the cold air control bar 400 located at the second position P2.

[0131] With this structure, since the horizontal movement of the cold air control rod 400 arranged between the shelf base 300 and the shelf body 200 is guided by the guide wall 303 at the bottom, and at the same time the movement of the guide member 435 above the cold air control rod 400 is guided by the guide rib 235, the movement of the cold air control rod 400 can be guided.

[0132] Fig.18 is Fig. 9 An enlarged view of area F is shown in FIG. Fig.19 is a top view of a first cold air control lever and a shelf base located at a first position according to an embodiment of the present disclosure. Fig. 20 is Fig.19 Magnified view of area I shown in . Fig.21 is a top view of a first cold air control lever and a shelf base located at a second position according to an embodiment of the present disclosure. Fig. 22 is Fig.21 Magnified view of area J shown in FIG.

[0133] refer to Figures 18 to 22 , except that switch 401 is connected to Figure 4 In addition to the structure that interferes with the front opening 201 shown in FIG. 1 , the cold air control lever 400 may also require a structure for the user to detect whether the cold air control lever 400 is in the first position P1 or the second position P2.

[0134] A pair of interference ribs 305 protruding forward (eg, +X direction) may be provided on the guide wall 303 of the shelf base 300. The pair of interference ribs 305 may be ribs protruding toward the guide plate 420 to be caught on the elastic protrusion 425 of the guide plate 420 of the cold air control bar 400.

[0135] Since the cold air control lever 400 moves between the first position P1 and the second position P2 when the seating portion 427 is supported by the guide wall 303 , the guide plate 420 may move between the first position P1 and the second position P2 to face the front surface 302 of the shelf base 300 .

[0136] The guide plate 420 may be provided with elastic protrusions 425 positioned at opposite sides. The elastic protrusions 425 may be provided in a pair and may include a first elastic protrusion 425a positioned at one side of the guide plate 420 and a second elastic protrusion 425b positioned at the other side of the guide plate 420.

[0137] The interference rib 305 may include a first interference rib 305a formed to interfere with the first elastic protrusion 425a and a second interference rib 305b formed to interfere with the second elastic protrusion 425b.

[0138] One end of each elastic protrusion 425 can be connected to the guide plate 420, and the other end of each elastic protrusion 425 can be separated from the guide plate 420 without being coupled. In this structure, the other end of the elastic protrusion 425 can be in a rotatable state while the one end connected to the guide plate 420 is fixed.

[0139] like Fig. 20 As shown, as the cold air control lever 400 located at the first position P1 is moved to the second position P2 by means of the switch 401, the first elastic protrusion 425a can interfere with the first interference rib 305a. The other end of the first elastic protrusion 425a that interferes with the first interference rib 305a can rotate around one end of the first elastic protrusion 425a. With this structure, when the cold air control lever 400 is moved from the first position P1 to the second position P2 using the switch 401, the user can sense that the cold air control lever 400 moves from the first position P1.

[0140] The other end of the first elastic protrusion 425 a may be rotated by the first interference rib 305 a , and when the guide plate 420 further moves in one direction (eg, the Y direction), the first elastic protrusion 425 a may return to its original position.

[0141] When the switch 401 moves from the first position P1 toward the second position P2 and reaches a position adjacent to the second position P2, one end of the second elastic protrusion 425b can rotate by interfering with the second interference rib 305b. With this structure, the user can recognize that the cold air control lever 400 has reached a position adjacent to the second position P2.

[0142] like Fig. 22 As shown, there may be a case where the user moves the cool air control lever 400 located at the second position P2 in one direction (eg, −Y direction) so as to open the first cool air communication hole 260 a .

[0143] As the switch 401 moves, the other end of the second elastic protrusion 425b of the cold air control lever 400 located at the second position P2 can rotate by interfering with the second interference rib 305b protruding forward, and then return to its original position after passing the second interference rib 305b. With this structure, as described above, the user can recognize that the cold air control lever 400 located at the second position P2 is moved.

[0144] On the other hand, even when the cold air control lever 400 moves to the first position P1, the first elastic protrusion 425a can move from one side of the first interference rib 305a and interfere with the first interference rib 305a. The cold air control lever 400 located at the first position P1 needs to stop moving to one side (for example, -Y direction) in a state where the opening and closing portion 460 fully opens the first cold air communication hole 260a, and in this case, as the first elastic protrusion 425a interferes with the first interference rib 305a, the user can sense the interference.

[0145] Fig.23 is a side cross-sectional view of a shelf according to an embodiment of the present disclosure. Fig.24 is an enlarged view of a cover rib provided on a lower surface of a shelf body according to an embodiment of the present disclosure. Fig.25 is a cut-away perspective view of a cover rib and a shelf base according to an embodiment of the present disclosure.

[0146] refer to Figure 23 to Figure 25 In the rack 100, the rack body 200 and the rack base 300 may be coupled to each other in a state where the rack base 300 is disposed below the rack body 200 so that the support wall 200d of the rack body 200 and the bottom wall 300d of the rack base 300 are separated from each other. The bottom wall 300d may cover the lower side of the support wall 200d. The support wall 200d may cover the bottom wall 300d. The support wall 200d and the bottom wall 300d may be disposed parallel to each other to form a gap G. Air may be contained in the gap G.

[0147] Using this structure, Figure 2 As shown, the second refrigerating chamber 21b separated by the shelf 100 and the shelf cover 110 can be maintained at a temperature lower than the temperature of the first refrigerating chamber 21a by about 1 degree Celsius or more. The second refrigerating chamber 21b, which is a space separated separately from the first refrigerating chamber 21a, can store food different from the food stored in the first refrigerating chamber 21a according to user preferences. This can be because the shelf cover 110 prevents the cold air in the second refrigerating chamber 21a from leaking into the first refrigerating chamber 21a.

[0148] Even when the food contained in the second refrigerating chamber 21b is stored according to the user's preference, the temperature of the second refrigerating chamber 21b may need to be controlled even when the temperature of the entire refrigerating chamber 21 is not controlled. That is, by moving the cold air control lever 400, the user can adjust the amount of cold air introduced into the second refrigerating chamber 21b through the first cold air communication hole 260a by fully opening, fully closing, or partially opening the first cold air communication port 260a.

[0149] That is, since cold air can be introduced into the second cold storage chamber 21b through the opening portions of the first cold air communicating hole 260a and the second cold air communicating hole 260b, the user can use the cold air control lever 400 to independently control the temperature of the second cold storage chamber 21b even without controlling the overall temperature of the cold storage chamber 21.

[0150] Even when the cold air introduced into the second refrigerating chamber 21b is controlled, the space adjacent to the first refrigerating chamber 21a in the second refrigerating chamber 21b may be affected by the first refrigerating chamber 21a. To prevent this, the shelf 100 may include an insulating space by leaving a gap G between the shelf body 200 and the shelf base 300.

[0151] More specifically, the shelf 100 may provide a separation space (e.g., a gap G) between the support wall 200d of the shelf body 200 and the bottom wall 300d of the shelf base 300 to thermally insulate the second refrigerating chamber 21a from the first refrigerating chamber 21a by air contained in the gap G. With this structure, since the second refrigerating chamber 21b is adjacent to the first refrigerating chamber 21a but may have a relatively independent space, the temperature in the second refrigerating chamber 21b may be separately maintained, thereby improving user satisfaction.

[0152] refer to Fig.24 and Fig.25 The cold air communication hole 260 located at the rear of the shelf 100 may be used to pass the cold air from the refrigerating chamber cold air duct 50 (see Figure 2 ) is configured such that the cold air discharged from the cold air outlet 60 is guided to the second refrigerating chamber 21 b of the shelf 100.

[0153] In addition, the cold air discharged from the cold air outlet 60 can not only flow through the cold air communication hole 260, but also flow into the first refrigerating chamber 21a located below the second refrigerating chamber 21b (e.g., in the -Z direction). With this structure, a part of the cold air can be introduced into the space between the shelf body 200 and the shelf base 300 through the space in which the opening and closing part 460 of the cold air control lever 400 moves ( Fig.24 in the CA direction).

[0154] Therefore, since cold air may be introduced into the gap G, which is the separation space between the shelf body 200 and the shelf base 300 described above, the second refrigerating chamber 21b may be easily affected by the temperature from the adjacent portion of the second refrigerating chamber 21b.

[0155] To prevent this, the shelf body 200 may include a cover rib 250 protruding from the bottom surface 210d toward the shelf base 300. The cover rib 250 may cover between the shelf body 200 and the shelf base 300. Because the cover rib 250 may prevent the cold air flow ( Fig.24 The CA direction) is introduced between the shelf body 200 and the shelf base 300, so the heat insulation structure of the shelf 100 can be maintained unchanged.

[0156] The cover rib 250 can extend to surround the horizontal connecting plate 457, extend to contact the first rear wall 300e of the shelf base 300 arranged on both sides to prevent the movement of the cold air control rod 400 located at the first position P1 and the cold air control rod 400 located at the second position P2, and the cover rib 250 is arranged as a pair spaced apart from each other so as not to interfere with the connecting portion 450.

[0157] In this structure, the cold air discharged through the cold air outlet 60 may be prevented from being introduced between the rack body 200 and the rack base 300 by the second cold air control bar 440 or the cover rib 250 .

Fig.32 is a front cross-sectional view of a shelf according to an embodiment of the present disclosure. Fig.33 is Fig.32 An enlarged view of area K is shown in FIG.

[0159] The following will refer to Figure 26 to Figure 33 The coupling structure of the shelf body 200 and the shelf base 300 is described.

[0160] refer to Fig.26The front coupling protrusion 211 protruding rearward (eg, −X direction) from the front wall 203 of the shelf body 200 may be inserted into the front coupling groove 311 formed on the front surface of the guide wall 303 of the shelf base 300 .

[0161] The shelf base 300 may include a front locking portion 311a forming a front coupling groove 311. The front coupling protrusion 211 of the shelf body 200 may be inserted into the front coupling groove 311 to be caught on the front locking portion 311a. In this way, a plurality of front coupling protrusions 211 of the shelf body 200 and the front coupling groove 311 of the shelf base 300 may be provided and arranged in a horizontal direction (e.g., a Y direction).

[0162] When the front coupling protrusion 211 of the shelf body 200 is coupled with the front locking portion 311 a of the shelf base 300 , the front portion of the shelf body 200 and the front portion of the shelf base 300 may be coupled and fixed to each other.

[0163] refer to Fig. 27 , the right coupling protrusion 213 protruding inward from the right wall 200c of the shelf body 200 may be inserted into the right coupling groove 313 of the shelf base 300. The right coupling protrusion 213 may be bent inward from the right wall 200c. Accordingly, the right coupling groove 313 may be formed on the bottom wall 300d of the shelf base 300. A plurality of right coupling protrusions 213 and right coupling grooves 313 may be provided and arranged along the front-rear direction (e.g., the X direction).

[0164] The left coupling protrusion 212 provided on the left wall 200 b of the shelf body 200 may be inserted into the left coupling groove 312 of the shelf base 300 , and the structure may be symmetrical with the structure in which the right coupling protrusion 213 is inserted into the right coupling groove 313 .

[0165] refer to Fig.28 The shelf body 200 may include a rear groove 214 formed at a lower portion of the first rear wall 200 e. The first rear wall 200 e may extend downward (eg, −Z direction) to cover a lower portion of the shelf base 300.

[0166] The bottom wall 300 d of the shelf base 300 may be configured to have a smaller area than the support wall 200 d of the shelf body 200 , and the bottom wall 300 d may include a rear protrusion 314 protruding from the first rear wall 300 e of the shelf base 300 toward the shelf body 200 .

[0167] The rear protrusion 314 may be formed to correspond to the position of the rear groove 214 so as to be inserted into the rear groove 214. A plurality of rear protrusions 314 and rear grooves 214 may be provided and arranged in one direction (eg, X direction), respectively.

[0168] When the plurality of rear protrusions 314 are inserted into the plurality of rear grooves 214 and captured on the rear locking portion 214 a of the first rear wall 200 e of the shelf body 200 , the rear portion of the shelf body 200 and the rear portion of the shelf base 300 may be coupled and fixed to each other.

[0169] like Figure 8 As shown, the second rear coupling protrusion 215 of the shelf body 200 may be inserted into the rear coupling groove 315 of the shelf base 300, and thus, the second rear wall 200f of the shelf body 200 and the second rear wall 300f of the shelf base 300 may be coupled to each other.

[0170] like Fig.29 As shown, a rear insertion protrusion 255 protruding from the rear surface 210f of the shelf body 200 toward the second rear wall 300f of the shelf base 300 may be provided. The second rear wall 300f of the shelf base 300 may face the rear surface 210f of the shelf body 200, and the second rear wall 300f may include a rear insertion groove 355 into which the rear insertion protrusion 255 is inserted.

[0171] The rear insertion protrusion 255 may be vertically arranged, and the rear insertion groove 355 may be vertically communicated so that the rear insertion protrusion 255 may be inserted into the rear insertion groove 355 .

[0172] With this structure, the shelf body 200 and the shelf base 300 may be assembled through the front portion, the left portion, the right portion, and the rear portion, respectively.

[0173] Since the shelf body 200 and the shelf base 300 may be relatively wide in the horizontal direction, a structure fixed to the inside thereof may be required.

[0174] refer to Figure 8 , Fig.30 and Fig.31 , the shelf base 300 may include a hook protrusion 320 formed on the bottom wall 300d. The hook protrusion 320 may be a configuration for hooking to the interference protrusion 220 provided on the bottom surface 210d of the shelf body 200.

[0175] When the multiple hook protrusions 320 arranged on the inner side of the shelf base 300 are hooked to the multiple interference protrusions 220 arranged on the inner side of the shelf body 200, in addition to the connection structure formed along the edge of the shelf body 200 and the edge of the shelf base 300, the connection along the inner side of the shelf body 200 and the inner side of the shelf base 300 is also completed, so that the connection force between the shelf body 200 and the shelf base 300 can be improved.

[0176] It may be difficult to check from the outside the positions of the plurality of hook protrusions 320 provided on the inner side of the shelf base 300. To prevent this, a guide hole 321 formed to penetrate the bottom wall 300d may be provided at a position adjacent to the hook protrusion 320. The guide hole 321 may be formed such that the hook portion of the hook protrusion 320 is exposed to the outside.

[0177] The guide hole 321 may be formed so that the position of the hook protrusion 320 of the shelf base 300 can be checked on the bottom surface 310g of the bottom wall 300d. Therefore, the user may press the guide hole 321 so that the hook protrusion 320 is hooked to the interference protrusion 220.

[0178] Furthermore, even when the shelf body 200 is separated from the shelf base 300, the coupling of the hook protrusion 320 with the interference protrusion 220 can be released by using a sharp member passing through the guide hole 321. According to this structure, the user can use the shelf 100 more easily because the inner part of the shelf body 200 and the inner part of the shelf base 300 can be coupled or separated.

[0179] The guide hole 321 may be formed on the bottom wall 300d of the shelf base 300, and the shelf base 300 may include a closing rib 322 extending to surround the guide hole 321 to prevent air for insulation purposes contained in the gap G between the shelf body 200 and the shelf base 300 from being discharged to the outside of the shelf 100 through the guide hole 321.

[0180] The closing rib 322 may extend to surround the guide hole 321 and contact the support wall 200 d of the shelf body 200 to prevent air contained between the shelf body 200 and the shelf base 300 from being discharged through the guide hole 321 .

[0181] With this structure, the shelf body 200 and the shelf base 300 contain air in a space therebetween, so that heat insulation can be maintained, and at the same time, the hook protrusion 320 and the interference protrusion 220 can be coupled relatively easily.

[0182] refer to Fig.32 and Fig.33 , the shelf 100 may be arranged to be horizontally longer in the left-right direction (e.g., Y direction) than in the front-back direction (e.g., X direction). Accordingly, the shelf body 200 may be arranged to be longer in the left-right direction (e.g., Y direction). Since the shelf body 200 stores food on the support wall 200d, the support wall 200d of the shelf body 200 may receive downward (e.g., -Z direction) weight due to the weight of the food.

[0183] In this case, since the shelf body 200 is provided to be long in one longitudinal direction (eg, the Y direction), the shelf body 200 may be bent downward in the longitudinal direction.

[0184] Since the shelf body 200 may no longer support food when bent downward, it is necessary to improve the durability of the shelf body 200 in the longitudinal direction. With this structure, the insertion rib 240 of the shelf body 200 extending in the front-to-back direction (e.g., X direction) can be inserted into the support groove 340a between the support ribs 340 of the shelf base 300. The support rib 340 and the support groove 340a can extend from the bottom wall 300d of the shelf base 300 toward the shelf body 200 to contact the support wall 200d of the shelf body 200.

[0185] The supporting ribs 340 may be provided in a pair so as to form a supporting groove 340a in the front-rear direction (e.g., the X direction), and the insert rib 240 may be inserted between the pair of supporting ribs 340. In this way, the pair of supporting ribs 340 may support the supporting wall 200d of the shelf body 200, wherein the insert rib 240 is located between the pair of supporting ribs 340.

[0186] In the absence of the configuration of the support ribs 340 , the rack body 200 may be bent along the imaginary line and thus the durability may be weak, but due to the configuration of the support ribs 340 , the durability of the rack body 200 may be improved to support food.

[0187] Fig.34 is Fig.10 An enlarged view of area H is shown in FIG. Fig.35 is an enlarged side sectional view of an opening and closing plate according to an embodiment of the present disclosure.

[0188] refer to Fig.34 and Fig.35 , the shelf base 300 may include a rear rib 360 formed on the second rear surface 310f. The rear rib 360 may be formed on the second rear surface 310f and disposed below the opening and closing portion 460 of the shelf 100 (eg, -Z direction).

[0189] The rear rib 360 may have a shape that is rounded downward in the horizontal direction. The rear rib 360 may also have a shape that is inclined downward.

[0190] The opening and closing portion 460 may include a first opening and closing wall 460 a , a second opening and closing wall 460 b , and a separation space 460 c formed between the first opening and closing wall 460 a and the second opening and closing wall 460 b .

[0191] The first opening and closing wall 460a and the second opening and closing wall 460b of the opening and closing portion 460 may be arranged to be spaced apart from each other in the front-rear direction (eg, X direction). More specifically, the first opening and closing wall 460a may be connected to the vertical connecting plate 458, and the second opening and closing wall 460b may be formed by bending from the first opening and closing wall 460a.

[0192] Even when the opening and closing portion 460 is closed with the cold air outlet 60 (see Figure 4 ) when the first cold air communicating hole 260a is connected to the first cold air outlet 60a, the cold air can also be discharged forward (for example, in the X direction) through the first cold air outlet 60a.

[0193] Air with relatively high humidity may be contained in the second refrigerating chamber 21b provided in front of the opening and closing portion 460. When the cold air discharged from the rear (e.g., X direction) of the opening and closing portion 460 encounters the air with high humidity and the opening and closing portion 460 is placed between the cold air discharged from the rear (e.g., X direction) of the opening and closing portion 460 and the air with high humidity, frost may be formed in an area adjacent to the opening and closing portion 460.

[0194] According to the structure in which the first opening and closing wall 460a and the second opening and closing wall 460b of the opening and closing portion 460 are spaced apart from each other in the front-rear direction (e.g., the X direction) to provide a separation space 460c between the first opening and closing wall 460a and the second opening and closing wall 460b, frost may be formed in the separation space 460c. When frost is formed in the separation space 460c, the frost may be invisible to the user's eyes due to the first opening and closing wall 460a. That is, since frost may be prevented from forming on the front surface of the first opening and closing wall 460a and thus the user may not see the frost, the user may feel more comfortable when using the refrigerator 1 (see FIG. 1 ). Figure 1 ) can feel comfortable.

[0195] On the other hand, when the opening and closing portion 460 is provided as a single opening and closing wall, frost may be formed on the front surface of the single opening and closing wall, so that the frost may be visible to the eyes of the user.

[0196] When the cold air control lever 400 is at the second position P2, the opening and closing portion 460 may be located at a closed position where the first cold air communication hole 260a is closed. In this case, the rear rib 360 of the shelf base 300 may be disposed below the separation space 460c of the opening and closing portion 460.

[0197] When frost formed in the separation space 460 c of the opening and closing portion 460 receives a downward force due to gravity or other reasons, the frost may move downward through the upper surface 360 ​​a of the rear rib 360 .

[0198] According to this structure, not only is the frost in the separation space 460c from the opening and closing portion 460 invisible to the user's eyes while being contained in the separation space 460c, but even when the frost moves downward, the frost can fall to the bottom plate of the refrigerating chamber 21 through the rear ribs 360, and even when the frost falls to the bottom plate of the refrigerating chamber 21, the frost can be invisible to the user's eyes.

[0199] Figure 36 to Figure 39 is a view illustrating a process in which a shelf body and a shelf base are coupled according to an embodiment of the present disclosure.

[0200] The following will refer to Figure 36 to Figure 39 The process of coupling the shelf base 300 and the shelf body 200 is described in detail.

[0201] In the coupling process of the shelf body 200 and the shelf base 300 , the shelf body 200 may be relatively easily disposed under the shelf base 300 and coupled thereto.

[0202] It will be appreciated that the cold air control bar 400 is disposed on the bottom surface 210 d of the shelf body 200 .

[0203] The front coupling groove 311 of the shelf base 300 may be positioned to correspond to the position of the front coupling protrusion 211 of the shelf body 200, and the front coupling protrusion 211 may be captured and fixed to the front locking portion 311a. In this way, since the plurality of front coupling protrusions 211 may be formed to be inserted into the front coupling groove 311 so as to be captured on each of the plurality of front locking portions 311a, the front portion of the shelf body 200 and the front portion of the shelf base 300 may be coupled to each other.

[0204] When the front coupling protrusion 211 is inserted into the front coupling groove 311 and is caught on the front locking portion 311a, the rear portion of the shelf base 300 can rotate while the front portion of the shelf base 300 is fixed. For example, the rear portion of the shelf base 300 can rotate clockwise.

[0205] After the rear portion of the shelf base 300 is rotated, the rear insertion groove 355 of the shelf base 300 may be rotated to correspond to the protruding shape of the rear insertion protrusion 255 of the shelf body 200 .

[0206] Thereafter, the bottom surface 310g of the shelf base 300 can be pressed downward so that along the edge of the bottom surface 310g of the shelf base 300 set above the shelf body 200, the left connecting protrusion 212 is inserted into the left connecting groove 312, the right connecting protrusion 213 is inserted into the right connecting groove 313, the rear protrusion 314 is inserted into the rear groove 214, and the rear connecting protrusion 215 is inserted into the rear connecting groove 315.

[0207] After the edge of the shelf body 200 and the edge of the shelf base 300 are coupled, the shelf body 200 and the shelf base 300 may be turned over so that the shelf body 200 is placed above the shelf base 300. In order to couple the inner side of the shelf body 200 and the inner side of the shelf base 300, the hook protrusion 320 and the interference protrusion 220 may be hooked by pressing one of the hook protrusion 320 and the interference protrusion 220 toward the other. That is, when the support surface 200g of the shelf body 200 is pressed against the shelf base 300, the hook protrusion 320 and the interference protrusion 220 may be hooked to each other.

[0208] However, the present disclosure is not limited to the contents shown in the drawings, and the hook protrusion 320 and the interference protrusion 220 may be hooked by pressing a portion near the guide hole 321 provided on the bottom surface 310 g of the shelf base 300 .

[0209] Through the above process, the rack body 200 and the rack base 300 can be coupled. Through this structure, the assembly of the rack 100 provided with the cold air control rod 400 can be completed.

[0210] Figure 40 to Figure 42 2 is a view illustrating a process of separating a shelf base from a shelf body according to an embodiment of the present disclosure.

[0211] The following will refer to Figure 40 to Figure 42 The structure for separating the shelf base 300 from the shelf body 200 is described in detail.

[0212] Similar to the structure in which the shelf base 300 and the shelf body 200 are coupled, the shelf base 300 may be disposed above the shelf body 200. In this state, the rear portion of the shelf base 300 may be separated from the rear portion of the shelf body 200 by pressing the rear locking portion 314a side of the shelf base 300 backward (e.g., in the -X direction).

[0213] Thereafter, the hook protrusion 320 formed on the inner side of the shelf base 300 can be separated from the interference protrusion 220 of the shelf body 200 through the guide hole 321 provided on the bottom surface 310g of the shelf base 300. In this process, in order to separate the hook protrusion 320 and the interference protrusion 220, a pressing member can be inserted through the guide hole 321 to rotate the hook protrusion 320, and thereby the hook protrusion 320 and the interference protrusion 220 can be more easily separated. Since the hook protrusion 320 has elasticity, the hook protrusion 320 can return to its original position after being rotated by the pressing member.

[0214] Thereafter, when the coupling structures positioned on both sides of the shelf body 200 and the shelf base 300 are separated, the rear portion of the shelf base 300 may be rotated around the front portion of the shelf base 300 .

[0215] The separation of the shelf body 200 from the shelf base 300 may be completed by separating the front coupling protrusion 211 of the shelf body 200 from the front coupling groove 311 of the shelf base 300 .

[0216] As described above, the coupling structure or the separation structure of the shelf body 200 and the shelf base 300 may be relatively easily guided by a plurality of coupling protrusions or the like, and at the same time, the coupling force between the shelf body 200 and the shelf base 300 may be increased.

[0217] Specific embodiments have been illustrated and described above. However, it should be understood by those skilled in the art that the present disclosure is not limited to the above embodiments and that various changes and modifications may be made without departing from the technical concept of the present disclosure described in the following claims.
