    Description

    BACKGROUND



    [0001] The present specification relates to a refrigerator.

    [0002] Generally, a refrigerator is a household appliance which can store food in an internal storage space which is shielded by a door at low temperatures, and the refrigerator is configured to store the stored food in an optical state by cooling an inside of the storage space using cold air generated by heat exchange with a refrigerant circulating in a refrigeration cycle.

    [0003] Such a refrigerator tends to be large-sized and multifunctional as the dietary life is changed and taste of a user is diversified and the refrigerator which has various storage spaces for the user's convenience and has a convenience device is released.

    [0004] Korean Patent Laid-Open Publication No. 10-2017-0138321, which is a related art, discloses a refrigerator.

    [0005] The refrigerator of the related art includes a cabinet in which a storage space is formed, a pantry assembly provided in the storage space and forming a receiving space for a separate food, and a shielding member which is provided on the pantry assembly and shields a portion of the upper surface of the pantry assembly.

    [0006] The pantry assembly includes a pair of support members disposed on both sides of the storage space, a receiving member provided between the pair of support members to pull in and out along the support member, a cover member which shields a portion of an opened upper surface of the receiving member and is moved in a direction opposite to a moving direction of the receiving member by being interlocked with pulling-in and out operations of the receiving member, and a drive unit which is provided on the support member and connects so that the receiving member and the cover member are interlocked with each other.

    [0007] The drive unit includes a second gear assembly coupled to the receiving member and moved in the same direction as the receiving member when the receiving member is pulled in and out, a first gear member coupled to the cover member and moved in the same direction as the cover member; a connecting gear rotatably provided between the second gear assembly and the first gear assembly and connecting the second gear assembly and the first gear member; and an elastic member for forcing the receiving member to be pulled in in a state where the receiving member and the second gear assembly are coupled.

    [0008] According to the related art, a user has to apply a force greater than the elastic force of the elastic member and the load of the receiving member in order to pull the receiving member.

    [0009] When the elastic force of the elastic member is increased, while a force by which a user pulls the receiving member is increased to make it difficult to open the receiving member, the receiving member is easily returned to the original position thereof by the elastic member in a process of pushing the receiving member in order to return the receiving member to an original position thereof. However, in a case where the elastic force of the elastic member is large, there is a disadvantage that the collision noise is large in a process of returning the receiving member to the original position.

    [0010] On the other hand, when the elastic force of the elastic member is small, a force to pull the receiving member is required to be small. However, there is a disadvantage that the load of the receiving member is larger than the force that the elastic member pulls the receiving member in a process of pushing the receiving member in order to return the receiving member to the original position thereof, so that the receiving member cannot be completely returned to the original position thereof only by the elastic force of the elastic member.

    [0011] EP 3 358 282 A1 relates to a refrigerator having a cabinet having a storage space; a door for opening and closing the storage space; a pair of support members, each provided at each of both sides of the storage space; a storage member which is provided between the pair of support members and pushed in and drawn out along the support member, and has an opening in the top surface so that food is inserted therethrough; a shielding member, provided above the storage member, for shieling a rear portion of the opening of the storage member; a cover member which shields a front portion of the opening of the storage member, is moved, as a result of the storage member being pushed in or drawn out, in the opposite direction to the direction in which the storage member is moved, and is moved rearward between the shielding member and the storage member when the storage member is drawn out; and a driving unit connecting the storage member and the cover member so as to make same move together. EP 3 358 282 A1 discloses the preamble of claim 1.

    [0012] US 2011/219808 A1 presents a refrigerator comprising a main body provided with a freezing chamber and a refrigerating chamber; a receiving member provided to be able to be drawn in and out to the main body and receiving foods; fixing members disposed on right and left sides of the receiving member and supporting the receiving members; entrance guide members provided between the receiving member and the fixing members and guiding sliding movement of the receiving members; and shaking prevention members provided on right and left sides of the receiving members and preventing a right and left shaking phenomenon of the receiving members.

    [0013] WO 2014/201615 A1 presents a refrigerator having a drawer structure comprising a drawer and a box cover. Two ends of the drawer are separately provided with a drawer support. Each drawer support is provided with a guide rail, a gear, and a first gear rack. The drawer is disposed on the guide rails and is provided with second gear racks. The first gear racks, the gears and the second gear racks form a transmission fit. The box cover is of an overturned structure and is connected to the first gear racks. When the drawer is drawn out, the second gear racks on the drawer drive the gears to rotate. The gears further drive, by means of rotation, the first gear racks to move along a direction opposite to the second gear racks. The first gear racks are connected to the box cover, and accordingly, can automatically drive the box cover to overturn inwards within a 180-degree range. The box cover does not move beyond a specific plane and does not affect work of a part above the specific plane.

    [0081] The cover member 580 and the drawer supporter 43 may be overlapped in the vertical direction in the pulling-in completion position of the receiving member 510.

    [0082] Fig. 4 is a perspective view illustrating the pantry assembly according to an embodiment of the present invention, Fig. 5 is an exploded perspective view illustrating the pantry assembly of Fig. 4, and Fig. 6 is a perspective view illustrating a state where a side cover is separated from the pantry assembly of Fig. 4.

    [0083] Referring to Figs. 4 to 6, the receiving member 510 may form the receiving space 511. The receiving member 510 may be formed in a rectangular parallelepiped shape having an opened top surface. So the receiving member 510 may have a box shape having an open top surface.

    [0084] The receiving member 510 may include a bottom wall 512, a pair of side walls 513 and 514 extending upward from both side ends of the bottom wall 512, and a rear wall 515 connecting rear ends of a pair of side walls 513 and 514.

    [0085] The receiving member 510 may further include a front opening 517 and the front opening 517 may be covered by a front cover 520 coupled to the front surface of the receiving member 510. A deco cover 522 may be coupled to a lower portion of the front cover 520.

    [0086] A cool air slot 516 for passing cool air may be formed in the rear wall 515 of the receiving member 510. The cool air slot 516 may be formed as a downwardly extending recess at the upper end of the rear wall 515.

    [0087] Each of the pair of side walls 513 and 514 of the receiving member 510 may be provided with a guide protrusion 518 extending in the front and rear direction. The guide protrusions 518 extend rearward from the front end portion of each of the side walls 513 and 514 and extend to a position spaced apart from the rear ends of the side walls 513 and 514 by a predetermined distance. So the guide protrusion 518 are shorter than a length of side wall 513, 514.

    [0088] The length of the guide protrusion 518 can be determined in consideration of a distance for pulling out the receiving member 510.

    [0089] A first roller supporter 513b to which the first roller 525 is coupled may be formed on each of the side walls 513 and 514 of the receiving member 510.

    [0090] The first roller supporter 513b may be positioned behind the guide protrusions 518 at the respective side walls 513 and 514. In other words, the first roller supporter 513b may be positioned behind the guide protrusion 518 and may be formed on a position adjacent to the rear ends of each of the side walls 513 and 514.

    [0091] The pair of supporters 530 supports the receiving member 510 and/or can guide pulling-in and out of the sliding of the receiving member 510.

    [0092] The guide rails 540 for guiding the first roller 525 of the receiving member 510 are provided on the surfaces of the pair of supporters 530 facing each other.

    [0093] The guide rails 540 protrude from the respective supporters 530 to receive the first rollers 525. At this time, the guide rails 540 protrude in a direction approaching each other at the respective supporters 530.

    [0094] The guide rail 540 include a first guide portion 541 and a second guide portion 542 spaced apart from the first guide portion 541 above the first guide portion 541.

    [0095] A space 540a is formed between the first guide portion 541 and the second guide portion 542 and the first roller 525 rotates in a state of being received in the space 540a, and can move along the guide rails 540.

    [0096] At this time, the vertical length/distance or space between the first guide portion 541 and the second guide portion 542 may be equal to or larger than the diameter of the first roller 525.

    [0097] In any case, the first roller 525 can move along the upper surface of the first guide portion 541 while rotating when the receiving member 510 is pulled in and out, in a state where the first roller 525 is seated on the upper surface of the first guide portion 541.

    [0098] Each of the guide portions 541 and 542 may include an inlet inclined portion 541a and 542a inclined in a direction away from each other, such that the first roller 525 of the receiving member 510 can be easily pulled in the space 540a of the guide rail 540 during the assembling process.

    [0099] In a process in which the receiving member 510 is pulled, in a state where the first roller 525 is received in a space 540a of the guide rail 540, each of the guide portions 541 and 542 include may inclined surfaces 541b and 542b inclined downward toward the rear side, so that the receiving member 510 can be easily moved to the pulling-in completion position.

    [0100] When the first roller 525 is positioned on each of the inclined surfaces 541b and 542b while moving along the upper surface of the first guide portion 541, the first roller 525 is inclined downward, and according to this, the receiving member 510 to which the first roller 525 is connected is inclined downward to move to the pulling-in completion position.

    [0101] In the present embodiment, the rear end portion of the first guide portion 541 and the rear end portion of the second guide portion 542 may be connected by a connection portion 543.

    [0102] The first roller 525 keeps a state where the first roller 525 is in contact with the inclined surfaces 541b and 542b in a state where the receiving member 510 is moved to the drawn-in complete position. The first roller 525 may be in contact with the connection portion 543.

    [0103] Accordingly, the connection portion 543 can serve as a stopper for stopping the receiving member 510 in a state where the receiving member 510 is moved to the pulling-in completion position.

    [0104] Each of the side walls 513 and 514 of the receiving member 510 may be provided with a transmission protrusion 519 for transmitting the movement force of the receiving member 510 to the cover member 580.

    [0105] The transmission protrusions 519 may be positioned above the guide protrusions 518 and/or may be approximately positioned at a central portion side in the front and rear direction of the respective side walls 513 and 514.

    [0106] When the receiving member 510 is slid in the first direction for pulling out the receiving member 510, the cover member 580 may slide in a second direction opposite to the first direction so that the receiving space 511 of the receiving member 510 is opened.

    [0107] At this time, the cover member 580 can be moved by receiving the movement force of the receiving member 510.

    [0108] Therefore, in the present embodiment, the supporter assembly may further include a transmission unit for transmitting the movement force of the receiving member 510 to the cover member 580.

    [0109] The transmission unit is supported by the supporter 530 and may be connected to the cover member 580.

    [0110] The transmission unit transmits the movement force of the receiving member 510 to the cover member 580 in some sections in a process of pulling in the receiving member 510 and does not transmit the moving force of the receiving member 510 to the cover member 580 in other sections.

    [0111] For example, the transmission unit transmits the movement force of the receiving member 510 to the cover member 580 until the receiving member 510 is drawn out by a predetermined distance from the pilling-in completion position.

    [0112] In a case where the receiving member 510 is pulled in by a distance greater than the predetermined distance from the pulling-in completion position, the transmission unit blocks that the movement force of the receiving member 510 is transmitted to the cover member 580.

    [0113] Specifically, the transmission unit includes a connection member 562 which is connected to the transmission protrusion 519 of the receiving member 510, a first rack 557 to which the connection member 562 is rotatably connected, a transmission gear 552 connected to the first rack 557, and a second rack 554 connected to the transmission gear 552 and coupled to the cover member 580.

    [0114] The transmission unit can be covered by a unit cover 570. The unit cover 570 may be coupled to the supporter 530. The unit cover 570 may be positioned at a side of the supporter being opposite to the side of the guide rail 540 with respect to the supporter 530 to cover the transmission unit.

    [0115] In addition, the transmission unit may further include an elastic member 560 connected to the first rack 557.

    [0116] The first rack 557 may include a first rack gear portion 557a connected to the transmission gear 552, as a straight rack moving in a linear direction. The gears of the first rack gear portion 557a may be disposed so as to face upward.

    [0117] The first rack 557 may further include a coupling body 557b which be disposed to be bent downward from the first rack gear portion 557a and to which the connection member 562 is coupled.

    [0118] The connection member 562 may be rotatably connected to the coupling body 557b. One end of the elastic member 560 may be connected to the coupling body 557b. The supporter 530 may have a fixing portion 549 to which the other end of the elastic member 560 is connected.

    [0119] The elastic member 560 may be a coil spring, for example and may extend in the horizontal direction in a state where the elastic member 560 is connected to the coupling body 557b and the fixing portion 549.

    [0120] The elastic member 560 accumulates elastic force in a process of pulling out the receiving member 510 and provides an elastic force to the receiving member 510 in a process of pulling the receiving member 510, thereby assisting the pulling-in of the receiving member 510.

    [0121] The transmission gear 552 may be a multi-stage gear. In other words, the transmission gear 552 may include a first gear 552a having a first diameter, and a second gear 552b having a second diameter larger than the first diameter.

    [0122] The first gear 552a and the second gear 552b are pinion gears whose rotational centers coincide with each other. The rotation center line of the transmission gear 552 may extend in the horizontal direction.

    [0123] The first gear 552a can be engaged with the first rack 557. For example, the first gear 552a may be connected to the first rack gear portion 557a at an upper side of the first rack gear portion 557a.

    [0124] This is to reduce the lateral thickness in the horizontal direction by the transmission unit. As the lateral thickness of the transmission unit in the horizontal direction increases, since the volume of the receiving member 510 decreases, the volume reduction amount of the receiving member 510 can be minimized by reducing the thickness of the transmission unit in the horizontal direction.

    [0125] The second rack 554 may include a second rack gear portion 555 which engages with the second gear 552b as a linear rack which moves in a linear direction.

    [0126] The second rack gear portion 555 is engaged with the second gear 552b on the upper side of the second gear 552b. This is to reduce the lateral thickness in the horizontal direction by the transmission unit.

    [0127] The gear ratio of the first gear 552a and the second gear 552b may be, for example, 1: 2. Therefore, the length of the second rack gear portion 555 is longer than the length of the first rack gear portion 557a.

    [0128] According to the present embodiment, the cover member 580 can be moved by a length longer than the moving length of the receiving member 510, so that the opening area of the receiving space 511 of the receiving member 510 can be increased.

    [0129] The receiving member 510 is positioned on one side of the supporter 530 and the transmission unit is positioned on the other side of the supporter 530. This is to prevent the transmission unit from being exposed in a process of pulling in and out the receiving member 510.

    [0130] Since the receiving member 510 and the transmission unit are positioned opposite to each other with respect to the supporter 530, so that the transmission protrusion 519 of the receiving member 510 can be connected to the transmission unit, the supporter 530 may be provided with a protrusion slot 547 through which the transmission protrusion 519 passes.

    [0131] The protrusion slot 547 may extend in the longitudinal direction of the supporter 530. At this time, the longitudinal direction is the front and rear direction of the supporter 530.

    [0132] The supporter 530 may further include a gear shaft 547a for rotatably supporting the transmission gear 552. The gear shaft 547a may be positioned above the protrusion slot 547.

    [0133] The supporter 530 may further include a first rack guide 546a for guiding the movement of the first rack 557 in a state of supporting the lower side of the first rack 557. For example, the coupling body 557b may be supported by the first rack guide 546a.

    [0134] The supporter 530 may further include a rack slot 539a through which the second rack 554 passes.

    [0135] The second rack 554 may further include a cover coupling rib 556 extending in the horizontal direction. The cover coupling rib 556 can pass through the rack slot 539a.

    [0136] The rack slot 539a can extend to be lengthen in a direction (for example, front and rear direction) parallel to the moving direction of the second rack 554 so as not to interfere with the cover coupling rib 556 of the second rack 554 which linearly moves.

    [0137] The supporter 530 may further include a stopper 539b for restricting the movement of the second rack 554 in a process of pulling in the receiving member 510.

    [0138] The stopper 539b is located behind the second rack 554 and when the cover member 580 opens the receiving space 511 in a process of pulling out the receiving member 510, the cover member 580 is stopped by restricting the movement of the second rack 554.

    [0139] The position at which the cover member 580 is stopped can be substantially the opening completion position of the cover member 580.

    [0140] The supporter 530 may further include a guide slot for guiding the movement of the connection member 562. The guide slot may be a groove shape formed by being recessed in the supporter 530.

    [0141] The guide slot may include a first slot 538a for guiding the linear movement of the connection member 562 and a second slot 538b which is bent at the front end of the first slot 538a and extends downward.

    [0142] The first slot 538a is formed in a linear shape. The second slot 538b extends inclinedly at a front end of the first slot 538a and extends inclinedly rearward at the first slot 538a.

    [0143] As will be described later, the connection member 562 may move along the first slot 538a and may be rotated in a process of moving from the front end portion of the first slot 538a toward a side of the second slot 538b.

    [0144] A connection frame 584 can be coupled to both sides of the cover member 580. The connection frame 584 is connected to the transmission unit to receive the movement force of the receiving member 510 through the transmission unit.

    [0145] The connection frame 584 prevents the cover member 580 from being damaged in a process of receiving the movement force of the receiving member 510.

    [0146] The cover member 580 may be formed in a form of a thin plate. When the cover member 580 is directly connected to the transmission unit, there is a possibility that the cover member 580 may be broken in a process of transmitting the moving force to the cover member 580, but, according to the present embodiment, this phenomenon can be prevented.

    [0147] Fig. 7 and Fig. 8 are perspective views illustrating a connection member according to an embodiment of the present invention.

    [0148] Referring to Figs. 7 and 8, the connection member 562 may include a space portion 563 formed by a portion of the upper surface thereof being recessed downward. The space portion 563 may receive the transmission protrusion 519 of the receiving member 510.

    [0149] The connection member 562 may include a front body 563b forming the space portion 563, a rear body 563c spaced apart from the front body 563b, and a lower body 563a forming a bottom of the space portion 563.

    [0150] Therefore, the transmission protrusion 519 can be received in the space portion 563 between the front body 563b and the rear body 563c.

    [0151] A first protrusion 564 and a second protrusion 565 which are spaced apart from each other in the horizontal direction may be provided on one surface of the lower body 563a.

    [0152] The first protrusions 564 and the second protrusions 565 may be arranged in a direction parallel to the linear movement direction of the connection member 562, for example.

    [0153] The first protrusions 564 may be disposed to overlap with the space portion 563 in the vertical direction. The second protrusions 565 may be positioned in front of the first protrusions 564 and may be disposed not to overlap with the space portion 563 in the vertical direction.

    [0154] A rack coupling shaft 566 for coupling with the first rack 557 may be provided on the other surface of the lower body 563a. For example, the rack coupling shaft 566 may be rotatably coupled to the coupling body 557b of the first rack 557.

    [0155] To this end, the rack coupling shaft 566 may be formed in a cylindrical shape so as to protrude from the other surface of the lower body 563a and so that the connection member 562 is be rotatable with respect to the first rack 557.

    [0156] The rack coupling shaft 566 may be positioned on the opposite side of the first protrusion 564 with respect to the lower body 563a. In other words, the first protrusions 564 may overlap with the rack coupling shaft 566 in the lateral horizontal directions.

    [0157] The first protrusion 564 and the second protrusion 565 may be received in the guide slot. For example, the first protrusion 564 and the second protrusion 565 may be located in the first slot 538a at the pulling-in completion position of the receiving member 510.

    [0158] The positional relationship of the first protrusion 564 and the second protrusion 565 in the guide slot in a process of pulling in the receiving member 510 will be described later with reference to the drawings.

    [0159] The lower body 563a may further include reinforcing grooves 569a, 569b, and 569c which are recessed so as to increase the strength of the lower body 563a while reducing the weight of the connection member 562. Although not limiting, one reinforcing groove 569a may be positioned around the rack coupling shaft 566.

    [0160] In addition, another reinforcing groove 569c may be disposed around the first protrusion 564.

    [0161] Fig. 9 is a side view illustrating a pantry assembly according to an embodiment of the present invention, Fig. 10 is an enlarged view illustrating portion A in Fig. 9, Fig. 11 is an enlarged view illustrating portion B in Fig. 9, Fig. 12 is an enlarged view illustrating portion C in Fig. 9.

    [0162] First, referring to Figs. 9 and 10, according to the invention, the elastic force of the elastic member 560 acts to the receiving member 510 in a process of pulling in the receiving member 510, thereby allowing the receiving member 510 to be automatically be pulled in.

    [0163] In the present embodiment, "automatic pull-in" means that the receiving member 510 can be pulled in even if the user removes the pushing force of the receiving member 510.

    [0164] When the elastic force (elastic modulus) of the elastic member 560 is increased as described above, the receiving member 510 can be automatically moved to the pulling-in completion position in a specific section in a process in which the receiving member 510 is pulled in. However, a collision noise may be generated in a process in which the receiving member 510 reaches the pull-in completion position. In addition, a force required by the user in the process of pulling out the receiving member 510 is large.

    [0165] Therefore, in the present embodiment, the pantry assembly 50 may further include a pulling-in guide structure which compensates for problems when using the elastic member 560. Due to the above-described pulling-in guide structure, a small amount of force is required in a process of pulling in the receiving member 510, and the collision noise in the pulling-in process can be reduced.

    [0166] The pulling-in guide structure may include the inclined surfaces 541b and 542b of the guide rail 540 as described above.

    [0167] When the first roller 525 of the receiving member 510 moves to the space between the inclined surfaces 541b and 542b while moving along the upper surface of the first guide portion 541, the roller 525 is rotated while being inclined downwardly by the inclined surfaces 541b and 542b so that the receiving member 510 can be stably and automatically moved to the pulling-in completion position.

    [0168] in a case of the present embodiment, the inclined surfaces 541b and 542b of the guide rail 540 are inclined downward with respect to the pulling-in direction of the receiving member 510. Therefore, when the receiving member 510 is pulled out, the first roller 525 is lifted along the inclined surfaces 541b and 542b.

    [0169] Since the first roller 525 is positioned on the rear end portion of the side walls 513 and 514 of the receiving member 510, although the first roller 525 is lifted along the inclined surfaces 541b and 542b, the front portion of the receiving member 510 may not be lifted due to the load of the receiving member 510.

    [0170] In this case, when the receiving member 510 linearly moves in an inclined state without being linearly moved in a horizontal direction, the load of the receiving member 510 acts as a moment of the first rack 557 and thus there is a possibility that the receiving member 510 is not smoothly pulled in and out.

    [0171] Therefore, this embodiment of the invention further includes a horizontal keeping structure which is lifted or lowered in a state the receiving member 510 forms a horizontal state when the first roller 525 is lifted or lowered along the inclined surfaces 541b and 542b.

    [0172] Specifically, referring to Figs. 9 and 11, the supporter 530 may be provided with a second roller 534 for supporting the guide protrusion 518 of the receiving member 510.

    [0173] The second roller 534 may be installed on surfaces facing each other in a pair of supporters 530.

    [0174] The second roller 534 may be positioned in front of the guide rail 540 in the supporter 530.

    [0175] The second roller 534 is in contact with the lower surface of the guide protrusion 518 and rotates by friction with the guide protrusion 518 in a process of pulling-in and out the receiving member 510, and thus facilitating the pulling-in and out of the receiving member 510.

    [0176] The guide protrusion 518 may include a lower rib 518a, an upper rib 518b positioned above the lower rib 518a, and a plurality of connection ribs 518c which connect the lower rib 518a and the upper rib 518b to each other.

    [0177] The lower rib 518a may be in contact with the second roller 534 in a process of pulling-in and out the receiving member 510.

    [0178] The upper rib 518b may extend in a linear shape in the horizontal direction.

    [0179] A portion of the lower rib 518a may extend in a straight line in the horizontal direction and may be parallel to the upper rib 518b. The other portion of the lower rib 518b may be inclined upward toward the front. The lower rib 518a may include an inclined rib 518d. In other words, the horizontal keeping structure may include the inclined ribs 518d.

    [0180] At this time, the inclination angle of the inclined ribs 518d may be the same as the inclination angle of the inclined surfaces 541b and 542b of the guide rails 540.

    [0181] The front end portion of the inclined rib 518d may be connected to the upper rib 518b. The inclined ribs 518d and the upper ribs 518b may be connected by one or more connection ribs 518c.

    [0182] Therefore, when the first roller 525 is lifted or lowered along the inclined surfaces 541b and 542b, the front side of the receiving member 510 is lifted or lowered together by the inclined ribs 518d.

    [0183] Next, referring to Figs. 9 and 12, the cover member 580 or the connection frame 584 may include a spacer rib 589 protruding downward. For example, the spacer ribs 589 may protrude downward from the connection frame 584.

    [0184] The spacer ribs 589 can be in contact with the upper surfaces of the side walls 513 and 514 of the receiving member 510 at the pulling-in completion position of the receiving member 510. For example, the spacer ribs 589 may be in contact with a side of the front end portion of the upper surface of the side walls 513 and 514.

    [0185] The cover member 580 and the upper surface of the receiving member 510 may be spaced apart from each other by the spacer ribs 589 at the pulling-in completion position of the receiving member 510.

    [0186] In other words, a gap G1 may exist between the cover member 580 and the receiving member 510. The gap G1 allows the refrigerating chamber 11 and the receiving space 511 of the receiving member 510 to communicate with each other at the pulling-in completion position of the receiving member 510. Therefore, cold air can circulate through the receiving space 511 and the refrigerating chamber 11.

    [0187] The refrigerator 1 may further include a temperature sensor (not illustrated) for sensing the temperature of the receiving space 511. The amount of cool air supplied to the receiving space 511 may be determined based on the temperature sensed by the temperature sensor.

    [0188] In a case where there is no gap between the cover member 580 and the receiving member 510, since the cool air stagnates in the receiving space 511 and the temperature sensed by the temperature sensor is lowered, the cold air is not allowed to flow into the receiving member 511. When the temperature of the receiving space 511 sensed by the temperature sensor increases, cool air is again supplied to the receiving space 511.

    [0189] As described above, when the cold air supply and supply interruption are repeated, the temperature change width of the food stored in the receiving space 511 becomes large, and the freshness of the food becomes low.

    [0190] On the other hand, according to the present embodiment, since the receiving space 511 and the refrigerating chamber 11 communicate with each other by the gap G1 existing between the cover member 580 and the receiving member 510 and thus the cool air can be circulated, the temperature change width of the food stored in the receiving space 511 can be minimized and freshness can be kept.

    [0191] In a case of the present embodiment, the receiving member 510 is lifted by the inclined surfaces 541b and 542b and the inclined ribs 518d in a process of pulling-out of the receiving member 510.

    [0192] In a case where the sidewalls 513 and 514 of the receiving member 510 have the same height, there is a problem that the sidewalls 513 and 514 interferes with the spacer ribs 589 in the process of pulling-out of the receiving member 510.

    [0193] Therefore, in the present embodiment, in order to prevent the side walls 513 and 514 of the receiving member 510 from interfering with the spacer ribs 589 in the process of pulling-out of the receiving member 510, each of the side walls 513 and 514 of the receiving member 510 may include a first wall 513a having a horizontal upper surface, an inclined wall 513b having an upper surface inclined downward as it goes backward from the first wall 513a, and a second wall 513c which extends rearward from the inclined wall 513b and has a horizontal upper surface.

    [0194] The height of the second wall 513c is equal to the minimum height of the inclined wall 513b and the height of the first wall 513a is equal to the maximum height of the inclined wall 513b.

    [0195] At this time, the inclination angle of the upper surface of the inclined wall 513b may be the same as the inclination angle of the inclined surfaces 541b and 542b of the guide rail 540.

    [0196] Thus, according to the present embodiment, in a process of the pulling-in of the receiving member 510, the receiving member 510 can be stably moved to the pulling-in completion position by the inclined surfaces 541b and 542b of the guide rail 540.

    [0197] In addition, in a process of pulling-out of the receiving member 510, the receiving member 510 can be moved in a state of being kept horizontal without being inclined forward and backward by the inclining rib 518d and the inclined wall 513b and thus there is an advantage that stable pulling-out is possible.

    [0198] Fig. 13 is a view illustrating a process of pulling out a receiving member according to an embodiment of the present invention in stages. Fig. 14 is a view illustrating a state of the connection member at a pulling-in completion position of the receiving member, and Fig. 15 is a view illustrating a state where a connection member is rotated according to an embodiment of the present invention. Fig. 16 is a perspective view illustrating a state where the receiving member has moved to the pulling-out completion position.

    [0199] Fig. 13 (a) illustrates a state where the receiving member is located at the pulling-in completion position, and Fig. 13 (b) illustrates a state where the receiving member is pulled out by the first distance at the pulling-in completion position.

    [0200] Fig. 13 (c) illustrates a state where the receiving member is pulled out by a second distance and the cover member has moved to the opening completion position, and Fig. 13 (d) illustrates a state where the receiving member has moved to the pulling-out completion position.

    [0201] Referring to Figs. 9 to 16, the transmission protrusion 519 of the receiving member 510 is positioned at the space portion 563 of the connection member 562 at the pulling-in completion position of the receiving member 510.

    [0202] The first protrusion 564 and the second protrusion 565 of the connection member 562 are located in the first slot 538a.

    [0203] In this state, when the receiving member 510 is pulled toward the user to pull out the receiving member 510, as illustrated in Fig. 13 (b), the receiving member 510 is moved linearly in the horizontal direction after being lifted to a predetermined height by the inclined surface 541b and 542b of the guide rail 540.

    [0204] At this time, in a case where the first protrusion 564 and the second protrusion 565 of the connection member 562 are positioned in the first slot 538a, in the process of pulling-out of the receiving member 510, the rotation of the connection member 562 is restricted and the connection member 562 can be linearly and moved stably.

    [0205] In a case where the connection member 562 linearly moves, the first rack 557 connected to the connection member 562 linearly moves in the first direction (arrow direction in Fig. 13).

    [0206] When the first rack 557 moves in the first direction, the transmission gear 552 is rotated in the clockwise direction in the drawing, and the rotation of the transmission gear 552 causes the second rack 554 to be linearly moved in a second direction opposite to the first direction.

    [0207] Then, the cover member 580 moves in the second direction together with the second rack 554, so that the receiving space 511 of the receiving member 510 is opened.

    [0208] In the present embodiment, the upper surface of the transmission protrusion 519 is positioned lower than the upper ends of the front body 563b and the rear body 563c forming the space portion 563.

    [0209] The height of the front body 563b is lower than the height of the rear body 563c. Therefore, the upper surface of the transmission protrusion 519 is positioned lower than the upper end 563d of the front body 563b.

    [0210] This is because the receiving member 510 is lifted by the inclined surfaces 541b and 542b of the guide rail 540 at the initial pulling-out of the receiving member 510, so that the transmission protrusion 519 prevents from being separated from the space portion 563.

    [0211] In addition, in order to prevent the transmission protrusion 519 from being separated, the upper surface of the transmission protrusion 519 is positioned at a position lower than the upper end 563d of the front body 563b at a position in which the transmission protrusion 519 is lifted.

    [0212] Therefore, even if the transmission protrusion 519 is lifted due to the lifting of the receiving member 510, the transmission protrusion 519 is kept in a state where the transmission protrusion 519 is positioned at the space portion 563, and thus the connection member 562 can be moved together when the transmission protrusion 519 is moved as illustrated in Fig. 13.

    [0213] In a process of pulling-out of the receiving member 510, the elastic member 580 is tensioned to accumulate the elastic force.

    [0214] In other words, when the receiving member 510 is pulled out, the transmission protrusion 519 is in contact with the front body 563b of the connection member 562 to push the front body 563b forward.

    [0215] Referring to Figs. 13 (c) and 14, when the second rack 554 is in contact with the stopper 539b in a process of pulling-out of the receiving member 510, the moving of the second rack 554 is restricted, and the cover member 580 is stopped.

    [0216] In the present embodiment, the position of the cover member 510 when the second rack 554 contacts the stopper 539b may be referred to as an opening completion position.

    [0217] If the movement force of the receiving member 510 is continuously transmitted to the cover member 580 in a state where the cover member 580 is stopped, the transmission unit and/or the cover member 580 can be broken.

    [0218] Therefore, the second protrusion 565 of the connection member 562 is aligned with the second slot 538b just before the cover member 580 is moved to the opening completion position and stopped. In this state, when the receiving member 510 is further pulled forward, the second protrusion 565 is moved to the second slot 538b, and the connection member 562 is rotated in this process.

    [0219] The connection member 562 is rotated around the rack coupling shaft 566. The guide slot may include a curved guide surface 538c which connects the first slot 538a and the second slot 538b to each other so that the second protrusion 565 smoothly moves into the second slot 538b in the first slot 538a.

    [0220] When the connection member 562 is rotated, the height of the front body 563b of the connection member 562 is lowered so that the front body 563b is deviated from the moving path of the transmission protrusion 519.

    [0221] Therefore, the transmission protrusion 519 can continuously move in the first direction without interfering with the front body 563b. On the other hand, the moving force of the transmission protrusion 519 is no longer transmitted to the connection member 562.

    [0222] Therefore, in a state where the cover member 580 is stopped, the receiving member 510 can move in the first direction.

    [0223] The elastic force of the elastic member 560 acts to the connection member 562 in a state where the second protrusion 565 is moved to the second slot 538b. The elastic member 560 acts as a force for pulling the connection member 562.

    [0224] In a case of the present embodiment, the second slot 538b is inclined downward from the front end portion of the first slot 538a toward the rear, although the elastic force of the elastic member 560 acts to the connection member 562 in a state where the second protrusion 565 is positioned to the second slot 538b, the connection member can be prevented from being rotated clockwise with reference to Fig.13 by the elastic member 560.

    [0225] Referring to Fig. 13 (d), in a state where the cover member 580 is stopped, the receiving member 510 can be continuously pulled out in the first direction. The pulling-out of the receiving member 510 may be restricted by a pulling-out restricting portion 518e provided in the receiving member 510 in a process of pulling out the receiving member 510.

    [0226] The position at which the pulling-out of the receiving member 510 is restricted and thus the receiving member 510 is stopped is the pulling-out completion position.

    [0227] For example, the pulling-out restricting portion 518e may be provided on the guide protrusion 518. The pulling-out restricting portion 518e may protrude downward from the rear end portion of the lower rib 518a.

    [0228] The pull-out restricting portion 518e is in contact with the second roller 534 of the supporter 530 at the pull-out completion position. The pulling-out restricting portion 518e may have a curved surface for surface contact with the second roller 534 so that the receiving member 510 is kept a state of being stopped at the pull-out completion position.

    [0229] Fig. 17 is a view illustrating a relative position between the center of gravity of the receiving member and the center of gravity of the cover member.

    [0230] Fig. 17 (a) illustrates a state where the cover member has moved to the opening completion position, Fig. 17 (b) illustrates a state where the first roller of the receiving member enters the inclined surface of the guide rail, and Fig. 17 (c) illustrates a state where the receiving member has moved to the pulling-out completion position.

    [0231] Referring to Figs. 9 to 17, the receiving member 510 can be pushed to be moved in the second direction so that the receiving member 510 which is moved to the pulling-out completion position is pulled in.

    [0232] Since the transmission protrusion 519 of the receiving member 510 is deviated from the space portion 563 of the connection member 562 at the beginning of the pulling-in of the receiving member 510, the connection member 562 keeps a state of being stopped at the time of moving of the receiving member 510. In other words, the cover member 580 keeps a state of being stopped at the opening completion position.

    [0233] Next, as illustrated in Fig. 17 (a), the transmission protrusion 519 is in contact with the rear body 563c of the connection member 562 in a process in which the receiving member 510 is pulled in.

    [0234] As illustrated above, since the height of the rear body 563c is higher than the height of the front body 563b, even if the connection member 562 is rotated in the process of pulling-out of the receiving member 510, the rear body 563c may be located on the path of the transmission protrusion 519.

    [0235] Accordingly, as illustrated in Fig. 17 (b), when the transmission protrusion 519 pushes the rear body 563c backward, the connection member 562 is rotated in the clockwise direction in the drawing, the transmission protrusion 519 are positioned in the space portion 563 of the connection member 562.

    [0236] In this state, when the receiving member 510 is continuously pulled in, the transmission protrusion 519 pushes the rear body 563c, so that the connection member 562 is moved in the second direction together with the receiving member 510.

    [0237] Then, the first rack 557 moves together with the connection member 562 in the second direction, and the transmission gear 552 is rotated counterclockwise in the drawing.

    [0238] As the transmission gear 552 rotates, the second rack 554 linearly moves in the first direction.

    [0239] Then, the cover member 580 moves in the first direction together with the second rack 554 to close the receiving space 511 of the receiving member 510.

    [0240] When the receiving member 510 rotates the connection member 562 so that the second protrusion 565 of the connection member 562 is moved to the first slot 538a in the second slot 538b, the elastic force of the elastic member 560 acts to the connection member 562 through the first rack 557.

    [0241] Then, since the elastic force of the elastic member 560 is transmitted to the receiving member 510, although the user remove the force pushing the receiving member 510, the receiving member 510 is automatically moved toward the pulling-in completion position by the elastic force of the elastic member 560.

    [0242] When the first roller 525 meets the inclined surfaces 541b and 542b of the guide rail 540 while the receiving member 510 is automatically slid along the pulling-in completion position, the receiving member 510 moves to the pulling-in completion position while the receiving member 510 is lowered by the inclined surface 541b and 542b.

    [0243] At this time, the inclined surfaces 541b and 542b automatically move the receiving member 510 to the pulling-in completion position even if there is no force to push the receiving member 510.

    [0244] Meanwhile, referring to Fig. 17 (c), the center of gravity C2 of the receiving member 510 and the center of gravity C1 of the cover member 580 at the pulling-in completion position of the receiving member 510 are located forward of the imaginary line A1 passing the rotation shaft of the transmission gear 552 vertically.

    [0245] The center of gravity C2 of the receiving member 510 is located closer to the imaginary line A1 than the center of gravity C1 of the cover member 580 at the pulling-in completion position of the receiving member 510.

    [0246] Referring to Fig. 17 (b), at the time when the first roller 525 of the receiving member 510 is in contact with the inclined surfaces 541b and 542b of the guide rail 540 in the process of pulling-in of the receiving member 510, the center of gravity C2 of the receiving member 510 and the center of gravity C1 of the cover member 580 are located forward of the imaginary line A1.

    [0247] At the time when the first roller 525 of the receiving member 510 is in contact with the inclined surfaces 541b and 542b of the guide rail 540, the center of gravity C2 of the receiving member 510 is located forward of the center of gravity C1 of the cover member 580.

    [0248] Referring to Fig. 17 (a), in a state where the cover member 580 is moved to the opening completion position, the center of gravity C2 of the receiving member 510 and the center of gravity C1 of the cover member 580 is positioned forward of the imaginary line A1 passing the rotation shaft of the transmission gear 552 vertically.

    [0249] The center of gravity C2 of the receiving member 510 is located forward of the center of gravity C1 of the cover member 580 in a state where the cover member 580 is moved to the opening completion position.

    [0250] In this state, the horizontal distance between the center of gravity C1 of the cover member 580 and the imaginary line A1 in the front and rear direction may be shorter than the radius of the transmission gear 552 (for example, the radius of the second gear).

    [0251] Fig. 18 is a plan view illustrating a pantry assembly according to an embodiment of the present invention, Fig. 19 is an enlarged view of Fig. 18 (D), Fig. 20 is a sectional view taken along line A-A in Fig. 19, and Fig. 21 is a sectional view taken along line B-B of Fig. 19.

    [0252] Referring to Figs. 18 to 21, the connection frame 584 may be coupled to the cover member 580. The connection frame 584 may be detachably coupled to the second rack 554 in a state where the connection frame 584 is coupled to the cover member 580.

    [0253] Therefore, the cover member 580 can be separated from the pantry assembly 50 in a state where the pantry assembly 50 is installed in the inner case 101.

    [0254] The cover member 580 may include an upper wall 580a, a pair of outer walls 580b extending downward from both ends of the upper wall 580a, and a front wall 580e extending downward from the front end of the upper wall 580a.

    [0255] The front wall 580c may connect the pair of outer walls 580b to each other.

    [0256] The cover member 580 may further include a pair of inside walls 580c spaced apart from each of the pair of outside walls 580b between the pair of outside walls 580b. Each of the inside walls 580c may extend downward from the lower surface of the cover member 580.

    [0257] The connection frame 584 may be received in a space between the inside wall 580c and the outside wall 580b.

    [0258] The connecting frame 584 may include a rib receiving slot 587 for receiving the cover coupling rib 556 of the second rack 554. The rib receiving slot 587 may be formed to have a predetermined length from the rear end portion of the connecting frame 584 toward the front end.

    [0259] The connection frame 584 may be partitioned into an upper frame 586 and a lower frame 585 with reference to the rib receiving slot 587.

    [0260] The upper frame 586 may include a recessed portion 586c formed by a portion of the upper surface thereof being recessed downward. The weight of the upper frame 586 can be reduced by the recessed portion 586c, and the strength thereof can be improved.

    [0261] The recessed portion 586c may be formed with a coupling wall 586a for coupling with the cover member 510. A coupling hole 586b may be formed in the coupling wall 586a.

    [0262] The upper surface wall 580a of the cover member 580 may be provided with a coupling hook 580d for coupling with the coupling wall 586a.

    [0263] In a process in which the connection frame 584 is received in the space between the inner wall 580c and the outer wall 580b, the coupling hook 580d is received in the recessed portion 586c and is hooked to the coupling hole 580b of the coupling wall 586a.

    [0264] A hook hole 556a is formed in the cover coupling rib 556 of the second rack 554 and the lower frame 585 may include a frame hook 587a for hooking the hook hole 556a.

    [0265] In a process in which the cover coupling rib 556 is received in the rib receiving slot 587, when the frame hook 587a is hooked to the hook hole 586a, the coupling of the connection frame 584 and the second rack 554 is completed. In the connection frame 584, the upper frame 586 may be provided with an opening 586d aligned with the hook hole 586a in the vertical direction.

    [0266] The user can press the frame hook 587a so that the frame hook 587a is separated from the hook hole 556a in a state where the tool is passed through the opening 586d from above the connecting frame 584. Then, the frame hook 587a may be disengaged from the hook hole 556a and thus the connecting frame 584 may be separated from the second rack 554.

    [0267] In the present embodiment, the connection frame 584 and the cover member 580 may be referred to as a cover unit.

    [0268] According to this embodiment, there is an advantage that the receiving member is automatically pulled in by the elastic member in a process in which the receiving member is moved from the pulling-out completion position to the pulling-in completion position and the receiving member can be automatically returned to the pulling-in completion position by the inclined surface of the guide rail.

    [0269] Therefore, there is an advantage that the elastic modulus of the elastic member can be reduced, and the force required for the pulling out of the receiving member can be reduced in a process of pulling out the receiving member.

    [0270] In addition, according to the present embodiment, since the diameter of the first gear connected to the connection member in the transmission gear is smaller than the diameter of the second gear connected to the cover member, there is an advantage that the sliding distance of the cover member compared to the pulling-out distance of the receiving member is increased and thus the opening area of the receiving member can be increased.

    [0271] In addition, according to the present embodiment, since the guide protrusion provided on the side wall of the receiving member includes the inclined rib, when the height is changed by the inclined surface in a process in which the receiving member is pulled in and out, there is an advantage that the entire receiving member can be kept horizontal without being inclined.

    [0272] In addition, in the present invention, since the connection frame is connected to the cover member and the connection frame is connected to the second rack of the transmission unit, in a process in which the cover member is operated to open and close the receiving space of the receiving member, the cover member can be prevented from being damaged.

    [0273] In addition, according to the present invention, the gap between the cover member and the receiving member is formed by the cover member or the spacer rib formed on the connection frame, so that the cool air flow is smooth, and in a state where the cover member covers the receiving space, a phenomenon in which the cover member tilts forward can be prevented.
