Referring to FIGS. 11 to 13, the cold air control lever 400 may include a first cold air control lever 410 including the switch 401, and a second cold air control lever 440 disposed on the rear of the first cold air control lever 410 and including an opening/closing part 460.


The first cold air control lever 410 may be moved in the horizontal direction (e.g., Y direction) by the movement of the switch 401, and the second cold air control lever 440 may be moved depending on a movement of the first cold air control lever 410 moved in the horizontal direction.


The first cold air control lever 410 may include a guide plate 420 connected to the switch 401, a seating part 427 disposed at the rear of the guide plate 420, and a connection part 430 bent from the seating part 427 and extending rearward.


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


The first cold air control lever 410 may include a guider 435 protruding from the connection part 430 in a moving direction (e.g., Y direction) of the first cold air control lever 410. The first cold air control lever 410 may include the guide protrusion 428 provided between the guider 435 and the seating part 427. The guide protrusion 428 may guide the movement of the first cold air control lever 410 in the horizontal direction by protruding from a bottom surface of the first cold air control lever 410 toward the shelf base 300 such that a front surface of the guide protrusion 428 comes into contact with the guide extension part 327 of the shelf base 300.


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


As illustrated in FIGS. 12 and 13, a length of the cold air control lever 400 may be adjusted in a front-rear direction (e.g., X direction) while the first cold air control lever 410 is inserted into the coupling part 450 through the insertion hole 450a. In order to adjust the length in the front-rear direction (e.g., X direction), the connection part 430 and the coupling part 450 are not coupled by a coupling member such as a screw, but the connection part 430 is supported by a supporter 455. With this structure, the cold air control lever 400 may be disposed on the shelves of the refrigerator 1 having various shapes, thereby increasing usefulness.



FIG. 14 is a perspective view of a cold air control lever seated on a shelf base and located in a first position according to an embodiment of the present disclosure. FIG. 15 is a perspective view of a cold air control lever seated on a shelf base and located 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.


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 moved between the first position P1 and the second position P2 by coming into contact with the shelf body 200, which movement will be described in detail below with reference to FIGS. 14 to 17.


When the cold air control lever 400 is in the first position P1, the second cold air control lever 440 may be located at an open position OP, and the coupling part 450 may come into contact with the right side of a first stopper 350a. Because a plurality of the first stoppers 350a protrudes from the base surface 310d and is arranged in the front-rear direction (e.g., X direction), the cold air control lever 400 may be prevented from moving to the left side (e.g., −Y direction) of the first stopper 350a.


The cold air control lever 400 may slide to the second position P2 depending on the movement of the switch 401 in the horizontal direction. At this time, the second cold air control lever 440 may be located in a closed position CP. When the second cold air control lever 440 is located in the closed position CP, the coupling part 450 may interfere with the left side of the second stopper 350b. Because the structure of the first stopper 350a is also applied to the second stopper 350b as described above, the cold air control lever 400 may be prevented from moving in the second position P2.


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


In addition, because the seating part 427 of the cold air control lever 400 may be moved in the horizontal direction along the guide wall 303 of the shelf base 300, the movement of the first cold air control lever 410 may be guided.


Because one surface of the guide protrusion 428 of the cold air control lever 400 may be moved in the horizontal direction while coming into contact with the guide extension part 327 of the shelf base 300, the movement of the first cold air control lever 410 may be guided.


The cold air control lever 400 positioned below the shelf body 200 may be guided to be moved between the first position P1 and the second position P2 in the horizontal direction by the guide rib 235 provided on the bottom surface 210d of the shelf body 200.


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


With this structure, because a movement in the horizontal direction below the cold air control lever 400 disposed between the shelf base 300 and the shelf body 200 is guided by the guide wall 303, and at the same time a movement of the guider 435 above the cold air control lever 400 is guided by the guide rib 235, the movement of the cold air control lever 400 may be guided.



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


Referring to FIGS. 18 to 22, in addition to the structure in which the switch 401 interferes with the front opening 201 shown in FIG. 4, the cold air control lever 400 may require a structure for a user to detect that the cold air control lever 400 is in the first position P1 or the second position P2.


The pair of interference ribs 305 protruding forward (e.g., +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 protrusions 425 of the guide plate 420 of the cold air control lever 400.


Because the cold air control lever 400 is moved between the first position P1 and the second position P2 while the seating part 427 is supported by the guide wall 303, the guide plate 420 may be moved between the first position P1 and the second position P2 to face the front surface 302 of the shelf base 300.


The guide plate 420 may be provided with the elastic protrusions 425 positioned on the opposite sides. The elastic protrusion 425 may be provided as a pair, and may include a first elastic protrusion 425a positioned on one side of the guide plate 420 and a second elastic protrusion 425b positioned on the other side of the guide plate 420.


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.


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


As illustrated in FIG. 20, as the cold air control lever 400 located at the first position P1 is moved to the second position P2 by the switch 401, the first elastic protrusion 425a may interfere with the first interference rib 305a. The other end of the first elastic protrusion 425a interfering with the first interference rib 305a may rotate about one end thereof. With this structure, the user may sense that the cold air control lever 400 is moved from the first position P1 when moving the cold air control lever 400 from the first position P1 to the second position P2 using the switch 401.


The other end of the first elastic protrusion 425a may be rotated by the first interference rib 305a, the first elastic protrusion 425a may return to an original position thereof when the guide plate 420 is further moved in one direction (e.g., Y direction).


When the switch 401 is moved 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 may be rotated by interfering with the second interference rib 305b. With this structure, the user may recognize that the cold air control lever 400 has reached a position adjacent to the second position P2.


As illustrated in FIG. 22, there may be a case in which the user moves the cold air control lever 400 located at the second position P2 in one direction (e.g., −Y direction) in order to open the first cold air communication hole 260a.


The other end of the second elastic protrusion 425b of the cold air control lever 400 located at the second position P2 may be rotated by interfering with the second interference rib 305b protruding forward as the switch 401 is moved, and then return to an original position thereof after passing the second interference rib 305b. With this structure, as described above, the user may recognize that the cold air control lever 400 located at the second position P2 is moved.


On the other hand, even when the cold air control lever 400 is moved to the first position P1, the first elastic protrusion 425a may be moved 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 the one side (e.g., −Y direction) in a state in which the opening/closing part 460 completely 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 may sense the interference.



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 cross-sectional perspective view of a cover rib and a shelf base according to an embodiment of the present disclosure.


Referring to FIGS. 23 to 25, in the shelf 100, the shelf body 200 and the shelf base 300 may be coupled to each other in a state in which the shelf base 300 is disposed below the shelf body 200 so that the support wall 200d of the shelf body 200 and the bottom wall 300d of the shelf base 300 are separated from each other. The bottom wall 300d may cover a 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 accommodated in the gap G.


With this structure, as illustrated in FIG. 2, the second refrigerating compartment 21b partitioned by the shelf 100 and the shelf cover 110 may be maintained at a temperature lower than that of the first refrigerating compartment 21a by about 1 degree Celsius or more. The second refrigerating compartment 21b, which is a space partitioned separately from the first refrigerating compartment 21a, may store food different from food stored in the first refrigerating compartment 21a depending on user preference. This may be because the shelf cover 110 prevents cold air in the second refrigerating compartment 21b from leaking into the first refrigerating compartment 21a.


Even when food accommodated in the second refrigerating compartment 21b is stored depending on the user preference, the temperature of the second refrigerating compartment 21b may need to be controlled even when the temperature of the entire refrigerating compartment 21 is not controlled. That is, by moving the cold air control lever 400, the user may adjust an amount of cold air introduced into the second refrigerating compartment 21b through the first cold air communication hole 260a by completely opening, completely closing, or partially opening the first cold air communication port 260a.


That is, because cold air may be introduced into the second refrigerating compartment 21b through the open portion of the first cold air communication hole 260a and the second cold air communication hole 260b, the user may independently control the temperature of the second refrigerating compartment 21b using the cold air control lever 400 even without controlling the entire temperature of the refrigerating compartment 21.


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


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


Referring to FIGS. 24 and 25, the cold air communication hole 260 positioned at the rear of the shelf 100 may be a configuration for guiding the cold air discharged from the cold air outlet 60 of the refrigerating compartment cold air duct 50 (see FIG. 2) to the second refrigerating compartment 21b of the shelf 100.


In addition, the cold air discharged from the cold air outlet 60 may flow not only through the cold air communication hole 260 but also into the first refrigerating compartment 21a positioned below the second refrigerating compartment 21b (e.g., −Z direction). With this structure, a part of the cold air may be introduced between the shelf body 200 and the shelf base 300 through a space in which the opening/closing part 460 of the cold air control lever 400 is moved (CA direction in FIG. 24).


Accordingly, because cold air may be introduced into the gap G, which is a separation space between the shelf body 200 and the shelf base 300 described above, the second refrigerating compartment 21b may be easily affected by a temperature from an adjacent part of the second refrigerating compartment 21b.


In order to prevent this, the shelf body 200 may include the cover rib 250 protruding toward the shelf base 300 from the bottom surface 210d. The cover rib 250 may cover between the shelf body 200 and the shelf base 300. Because the cover rib 250 may prevent the flow of cold air (CA direction in FIG. 24) from being introduced between the shelf body 200 and the shelf base 300, the insulation structure of the shelf 100 may be maintained as it is.


The cover rib 250 may extend to surround the horizontal connection plate 457, extend to be in contact with the first rear wall 300e of the shelf base 300 disposed on both sides to prevent the movement of the cold air control lever 400 located at the first position P1 and the cold air control lever 400 located at the second position P2, and be provided as a pair spaced apart from each other so as not to interfere with the coupling part 450.


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

FIG. 28 is a cross-sectional view taken along line D-D′ shown in FIG. 4. FIG. 29 is a cross-sectional perspective view illustrating a combination of a shelf body and a shelf base according to an embodiment of the present disclosure from the rear. FIG. 30 is an enlarged view of area E shown in FIG. 8. FIG. 31 is an enlarged cross-sectional view taken along line C-C′ shown in FIG. 4. FIG. 32 is a front cross-sectional view of a shelf according to an embodiment of the present disclosure. FIG. 33 is an enlarged view of area K shown in FIG. 32.


A coupling structure of the shelf body 200 and the shelf base 300 will be described below with reference to FIGS. 26 to 33.


Referring to FIG. 26, the front coupling protrusion 211 protruding rearward (e.g., −X direction) from the front wall 203 of the shelf body 200 may be inserted into the front coupling groove 311 formed on a front surface of the guide wall 303 of the shelf base 300.


The shelf base 300 may include a front locking part 311a forming the 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 part 311a. As such, a plurality of the front coupling protrusions 211 of the shelf body 200 and the front coupling grooves 311 of the shelf base 300 may be provided and arranged in the horizontal direction (e.g., Y direction).


When the front coupling protrusion 211 of the shelf body 200 and the front locking part 311a of the shelf base 300 are coupled, front portions of the shelf body 200 and the shelf base 300 may be coupled and fixed to each other.


Referring 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. Correspondingly, the right coupling groove 313 may be formed on the bottom wall 300d of the shelf base 300. A plurality of the right coupling protrusions 213 and the right coupling grooves 313 may be provided and arranged in the front-rear direction (e.g., X direction).


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


Referring to FIG. 28, the shelf body 200 may include the rear groove 214 formed at a lower portion of the first rear wall 200e. The first rear wall 200e may extend downward (e.g., −Z direction) to cover a lower portion of the shelf base 300.


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


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


When the plurality of rear protrusions 314 is inserted into the plurality of rear grooves 214 and caught on the rear locking part 214a of the first rear wall 200e of the shelf body 200, rear portions of the shelf body 200 and the shelf base 300 may be coupled and fixed to each other.


As shown in FIG. 8, 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 accordingly, 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.


As illustrated in FIG. 29, a rear insertion protrusion 255 protruding from a 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 include a rear insertion groove 355 into which the rear insertion protrusion 255 is inserted.


The rear insertion protrusion 255 may be arranged vertically, and the rear insertion groove 355 communicates vertically such that the rear insertion protrusion 255 may be inserted therein.


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


Because the shelf body 200 and the shelf base 300 may be wide in the horizontal direction, structures to be fixed to the insides thereof may be required.


Referring to FIGS. 8, 30, and 31, the shelf base 300 may include the hook protrusion 320 formed on the bottom wall 300d. The hook protrusion 320 may be a configuration for being hooked to the interference protrusion 220 provided on the bottom surface 210d of the shelf body 200.


When the plurality of hook protrusions 320 disposed on an inner side of the shelf base 300 is hooked to the plurality of interference protrusions 220 disposed on an inner side of the shelf body 200, in addition to the coupling structure formed along edges of the shelf body 200 and the shelf base 300, coupling of the inner sides of the shelf body 200 and the shelf base 300 is completed, so that a coupling force between the shelf body 200 and the shelf base 300 may be increased.


It may be difficult to check positions of the plurality of hook protrusions 320 disposed on the inner side the shelf base 300 from the outside. In order to prevent this, the 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 a hook portion of the hook protrusion 320 is exposed to the outside.


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


In addition, even when the shelf body 200 and the shelf base 300 are separated, the coupling of the hook protrusion 320 and the interference protrusion 220 may be released by using a sharp member through the guide hole 321. According to this structure, the user may more easily use the shelf 100 because the inner parts of the shelf body 200 and the shelf base 300 may be coupled or separated.


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 closed rib 322 extending to surround the guide hole 321 to prevent air accommodated in the gap G between the shelf body 200 and the shelf base 300 for the purpose of insulation from being discharged to the outside of the shelf 100 through the guide hole 321.


The closed rib 322 may extend to surround the guide hole 321 and be in contact with the support wall 200d of the shelf body 200 to prevent air accommodated between the shelf body 200 and the shelf base 300 from being discharged through the guide hole 321.


With this structure, the shelf body 200 and the shelf base 300 accommodate air in the space therebetween so that insulation may be maintained, and at the same time, the hook protrusion 320 and the interference protrusion 220 may be coupled relatively easily.


Referring to FIGS. 32 and 33, the shelf 100 may be provided to be horizontally longer in a left-right direction (e.g., Y direction) than in the front-rear direction (e.g., X direction). Correspondingly, the shelf body 200 may be provided to be long in the left-right direction (e.g., Y-direction). Because the shelf body 200 stores food on the support wall 200d, due to a weight of the food, the support wall 200d of the shelf body 200 may receive the weight downward (e.g., −Z direction).


In this case, because the shelf body 200 is provided to be long in one longitudinal direction (e.g., Y direction), the shelf body 200 may be bent downward in the longitudinal direction.


Because the shelf body 200 may no longer support food when bent downward, durability of the shelf body 200 in the longitudinal direction needs to be improved. For this structure, the insertion rib 240 of the shelf body 200 extending in the front-rear direction (e.g., X direction) may 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 may extend from the bottom wall 300d of the shelf base 300 toward the shelf body 200 to be in contact with the support wall 200d of the shelf body 200.


The support ribs 340 may be provided as a pair to form the support groove 340a in the front-rear direction (e.g., X direction), and the insertion rib 240 may be inserted between the pair of support ribs 340. As such, the pair of support ribs 340 may support the support wall 200d of the shelf body 200 with the insertion rib 240 therebetween.


In a case in which there is no configuration of the support rib 340, the shelf body 200 may be bent in a dotted line, and thus the durability may be weak, but due to the configuration of the support ribs 340, the durability of the shelf body 200 may be improved to support food.



FIG. 34 is an enlarged view of area H shown in FIG. 10. FIG. 35 is an enlarged side cross-sectional view of an opening/closing plate according to an embodiment of the present disclosure.


Referring to FIGS. 34 and 35, the shelf base 300 may include the rear rib 360 formed on the second rear surface 310f. The rear rib 360 may be formed on the second rear surface 310f and provided below the opening/closing part 460 of the shelf 100 (e.g., −Z direction).


The rear rib 360 may have a shape rounded downward in the horizontal direction. The rear rib 360 may also have a downwardly inclined shape.


The opening/closing part 460 may include a first opening/closing wall 460a, a second opening/closing wall 460b, and a separation space 460c formed between the first opening/closing wall 460a and the second opening/closing wall 460b.


The first opening/closing wall 460a and the second opening/closing wall 460b of the opening/closing part 460 may be provided to be spaced apart from each other in the front-rear direction (e.g., X direction). More specifically, the first opening/closing wall 460a may be connected to the vertical connection plate 458, and the second opening/closing wall 460b may be formed by being bent from the first opening/closing wall 460a.


Even when the opening/closing part 460 closes the first cold air communication hole 260a communicating with the first cold air outlet 60a of the cold air outlet 60 (see FIG. 4), cold air may be discharged forward (e.g., X direction) through the first cold air outlet 60a.


Air with relatively high humidity may be accommodated in the second refrigerating compartment 21b provided in front of the opening/closing part 460. When cold air discharged from the rear of the opening/closing part 460 (e.g., −X direction) encounters air with high humidity with the opening/closing part 460 interposed therebetween, frost may form in an area adjacent to the opening/closing part 460.


According to a structure in which the first opening/closing wall 460a and the second opening/closing wall 460b of the opening/closing part 460 are spaced apart from each other in the front-rear direction (e.g., X direction) to provide the separation space 460c therebetween, frost may form in the separation space 460c. When frost forms in the separation space 460c, the frost may be invisible to eyes of the user by the first opening/closing wall 460a. That is, because frost may be prevented from forming on a front surface of the first opening/closing wall 460a, and thus the user does not see frost, the user may feel comfortable in using the refrigerator 1 (see FIG. 1).


On the other hand, when the opening/closing part 460 is provided as a single opening/closing wall, frost may form on a front surface of the single opening/closing wall, so that the frost may be visible to the eyes of the user.


When the cold air control lever 400 is in the second position P2, the opening/closing part 460 may be located at the 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/closing part 460.


When frost formed in the separation space 460c of the opening/closing part 460 is forced downward due to gravity or other causes, the frost may move downward through the upper surface 360a of the rear rib 360.


According to this structure, because not only is frost invisible to the eyes of the user while the frost that may from in the separation space 460c of the opening/closing part 460 is accommodated in the separation space 460c, but the frost may fall to the floor of the refrigerating compartment 21 through the rear rib 360 even when moving downward, even while the frost falls to the floor of the refrigerating compartment 21, the frost may be invisible to the eyes of the user.



FIGS. 36 to 39 are views illustrating a process in which the shelf body and a shelf base are coupled according to an embodiment of the present disclosure.


A process of coupling the shelf base 300 and the shelf body 200 will be described in detail below with reference to FIGS. 36 to 39.


In the process of coupling the shelf body 200 and the shelf base 300, it may be relatively easy for the shelf body 200 to be disposed below the shelf base 300 and coupled thereto.


It will be understood that the cold air control lever 400 is seated on the bottom surface 210d of the shelf body 200.


The front coupling groove 311 of the shelf base 300 may be positioned corresponding to a position of the front coupling protrusion 211 of the shelf body 200, and the front coupling protrusion 211 may be caught on and fixed to the front locking part 311a. As such, because the plurality of front coupling protrusions 211 may be formed to be inserted into the front coupling groove 311 so as to be caught on each of the plurality of front locking parts 311a, the front portions of the shelf body 200 and the shelf base 300 may be coupled to each other.


When the front coupling protrusion 211 is inserted into the front coupling groove 311 and caught on the front locking part 311a, the rear portion of the shelf base 300 may be rotated while the front portion thereof is fixed. For example, the rear portion of the shelf base 300 may be rotated clockwise.


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 a protruding shape of the rear insertion protrusion 255 of the shelf body 200.


Thereafter, the bottom surface 310g of the shelf base 300 may be pressed downward so that along an edge of the bottom surface 310g of the shelf base 300 disposed above the shelf body 200, the left coupling protrusion 212 is inserted into the left coupling groove 312, the right coupling protrusion 213 is inserted into the right coupling groove 313, the rear protrusion 314 is inserted into the rear groove 214, and the rear coupling protrusion 215 is inserted into the rear coupling groove 315.


After the edges of the shelf body 200 and 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 disposed above the shelf base 300. In order to couple the inner sides of the shelf body 200 and 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 one. 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 with each other.


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


The coupling of the shelf body 200 and the shelf base 300 may be completed through the above process. Through this structure, the combination of the shelf 100 provided with the cold air control lever 400 may be completed.



FIGS. 40 to 42 are views illustrating a process in which a shelf base is separated from a shelf body according to an embodiment of the present disclosure.


A structure for separating the shelf base 300 from the shelf body 200 will be described in detail below with reference to FIGS. 40 to 42.


Like 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 part 314a side of the shelf base 300 rearward (e.g., −X direction).


Thereafter, the hook protrusion 320 formed on the inner side of the shelf base 300 may 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 may be inserted through the guide hole 321 to rotate the hook protrusion 320, and thus the hook protrusion 320 and the interference protrusion 220 may be separated more easily. Because the hook protrusion 320 has elasticity, the hook protrusion 320 may return to an original position thereof after being rotated by the pressing member.


Thereafter, while 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 thereof.


Separation of the shelf body 200 and 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.


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


The foregoing has illustrated and described specific embodiments. However, it should be understood by those of skilled in the art that the present disclosure is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the technical idea of the present disclosure described in the following claims.
