Description
TECHNICAL FIELD

The present invention relates to a refrigerator, and more particularly to a receiving unit configured to efficiently utilize space for storing objects to be refrigerated or frozen and structures of a door and a cover for opening and closing the receiving unit.


BACKGROUND ART

A refrigerator is an apparatus for storing storage objects (objects to be refrigerated or frozen) received in a storage space in a refrigerated or frozen state through a cycle constituted by compression, condensation, expansion and evaporation of refrigerant. In other words, a conventional refrigerator is provided with a storage space for receiving storage objects and a heat exchange unit for absorbing heat from the air in the storage space so as to maintain the storage objects disposed in the storage space at a temperature lower than the ambient temperature.


Because the volume of the storage space is restricted by the storage capacity set for the refrigerator, designing the storage space to be efficiently utilized is one of the critical factors in the design of a refrigerator.


For efficient utilization of the storage space, a conventional refrigerator is provided therein not with a space for receiving storage objects but with a drawer configured to be put into and taken out of the storage space and shelves for supporting the storage objects.


Because the storage space provided in the refrigerator is partitioned by drawers, shelves or the line in consideration of the volume of storage objects, the number or the volume of receiving components (shelves, drawers and the like) capable of being mounted in the storage space having the maximum volume, which is determined according to the capacity of the refrigerator, is inevitably restricted.


This means that some of the drawers and shelves have to be omitted, the volume of the drawers has to be reduced, or the distance between the shelf and the drawer or the distance between the shelves has to be reduced in order to add additional receiving component space to the storage space in the refrigerator. The reason for this is because, in order to add a new receiving component, a portion of the storage space has to be used as a space required to accommodate installation of the receiving component.


However, a change of design in which the number or the volume of drawers and shelves is reduced for installation of a new receiving component may cause a problem whereby the drawers or shelves cannot accommodate the amount of storage objects that is determined at the time of design, thereby decreasing storage efficiency.


In addition, because a change of design in which the number or the volume of drawers and shelves is reduced for installation of a new receiving component is no different from the design of a new storage space, it is difficult to add a new receiving component to a conventional refrigerator while maintaining the volume of the storage space that is already designed.

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.



FIG. 1 is a front view of a refrigerator according to an embodiment of the present invention, in which a storage compartment door is open.


The refrigerator according to the present invention may be applied to both a top-mount type refrigerator, in which a refrigerating compartment and a freezing compartment for storing foodstuffs are isolated from each other upwards and downwards and the freezing compartment is located above the refrigerating compartment, and a side-by-side type refrigerator, in which a freezing compartment and a refrigerating compartment are isolated from each other right and left.


However, this embodiment will be described with a focus on a bottom-freezer type, in which a refrigerating compartment and a freezing compartment are isolated from each other upwards and downwards and the freezing compartment is located below the refrigerating compartment, for convenience of explanation.


The refrigerator includes a case or a cabinet 1, which defines the overall appearance of the refrigerator when viewed from the outside by a user, and storage compartments 11 and 13, which are defined in the cabinet 1 so as to store foodstuffs.


The refrigerator includes doors 20 and 30 for opening and closing the storage compartments. The doors may include a freezing compartment door 30 and a refrigerating compartment door 20, each of which is rotatably coupled at one end thereof to the cabinet 1 of the refrigerator via a hinge. Each of the doors 30 and 20 may be composed of a plurality of doors. In other words, each of the refrigerating compartment door 20 and the freezing compartment door 30 may be composed of a pair of doors, which are configured to be opened forwards about opposite lateral sides of the refrigerator, as illustrated in FIG. 1.


The storage compartments 11 and 13 define insulated spaces, which are isolated from the outside by means of the doors 20 and 30. The storage compartments 11 and 13 may define insulated spaces, which are isolated from the outside when the doors 20 and 30 close the storage compartments 11 and 13. In other words, the storage compartments 11 and 13 may be considered as spaces, which are thermally isolated from the outside by means of the insulated walls constituted by the doors 20 and 30 and the insulated wall constituted by the cabinet 1.


Since cold air supplied from a machinery room is introduced into and circulated in the storage compartments 11 and 13, it is possible to maintain the foodstuffs stored in the storage compartments at a low temperature. In this embodiment, the storage compartment that is positioned at the upper side of the refrigerator may be referred to as a first storage compartment. For example, the first storage compartment may be the refrigerating compartment. The storage compartment that is positioned at the lower side of the refrigerator may be referred to as a second storage compartment. For example, the second storage compartment may be the freezing compartment. The first storage compartment may be composed of a single storage compartment, which is opened and closed by means of left and right doors 20, and the second storage compartment may be composed of a pair of storage compartments, which are isolated from each other right and left and are opened and closed by left and right doors 30.


The storage compartment 11 may be provided at the bottom thereof with a barrier or a partition wall 15. Specifically, the storage compartment 11 may be provided at the lower end thereof with the partition wall 15 so as to isolate the refrigerating compartment from the freezing compartment. The partition wall 15 may have a predetermined thickness and may extend horizontally.


The storage compartment 22 may include a shelf 40 on which foodstuffs are placed. The shelf 40 may be composed of a plurality of shelves, on any of which foodstuffs are placed. The shelf 40 may partition the internal space of the storage compartment horizontally.


The storage compartment may be provided with a drawer 50, which is capable of being put into or drawn out of the storage compartment 11. The drawer 50 contains foodstuffs and the like. The drawer 50 may be composed of a pair of drawers, which are positioned at right and left sides in the storage compartment 12. A user may open the left door in order to access to the drawer disposed at the left side. Similarly, a user may open the right door in order to access to the drawer disposed at the right side.


The partition wall 15 may be provided with a space for containing foodstuffs. The space may be referred to as a multi-receiving compartment or a receiving unit P. The partition wall 15 may be constructed separately from the doors 20 and 30. Accordingly, the partition wall 15 may remain in place without moving even when the doors 20 and 30 are rotated. Consequently, a user may reliably put foodstuffs into the storage compartment by virtue of the receiving unit P, or may reliably take the foodstuffs out of the storage compartment by virtue of the receiving unit P.


The storage compartment 11 may be partitioned into a plurality of spaces for storing foodstuffs, that is, a space positioned above the shelf 40, a space defined by the drawer 50, and the receiving unit P, defined by the partition wall 15.


The receiving unit P may be depressed downwards from the partition wall 15, which defines the lower surface of the storage compartment 11. In other words, the receiving unit P may be formed by reducing the thickness of the partition wall 15 somewhat. Accordingly, the internal volume of the storage compartment 11 may be increased by virtue of the receiving unit P.


Cold air supplied to the storage compartment 11 may be introduced into all of the spaces defined in the single storage compartment 11. Specifically, since cold air is able to flow among the spaces, the spaces may be considered to be conceptually different from the above-described storage compartments.


Specifically, unlike the storage compartments which define insulated spaces, the spaces are not insulated from each other, although there may be a temperature difference between the spaces.


Cold air supplied to one of the storage compartments cannot flow into another storage compartment but can freely flow into any of the spaces defined in the storage compartment. In other words, cold air, which is positioned above the shelf 40, may flow into the space defined by the drawer 50.


The refrigerating compartment door 20 may be provided therein with a plurality of baskets 80. The plurality of baskets 80 may be disposed at different heights from each other, and foodstuffs may be stored in the internal space defined in the baskets 80.


A gap G may be defined between the upper surface of the partition wall 15, that is, the lower surface of the storage compartment 11 and a separate storage space such as the drawer 50. The gap G is intended to provide a space for allowing a receiver door, adapted to open and close a receiver to be described later, to be moved therethrough. Accordingly, the gap G may be formed at a height corresponding to the height of the receiver door having a horizontal plate shape. In other words, the gap G may have a height such that only the receiver door can be smoothly moved therethrough.


Hereinafter, the receiving unit P according to an embodiment of the present invention will be described in more detail.


As illustrated in FIG. 2, the refrigerator 100 according to an embodiment of the present invention may include the cabinet 1, the storage compartments, which are provided in the cabinet 1 to provide a space for receiving storage objects (objects to be refrigerated or objects to be frozen), and a heat exchange unit for exchanging heat with the internal air in the storage compartments.


The storage compartments may be provided in a plural number in the cabinet 1. FIG. 2 illustrates an example in which the storage compartment is divided into the first storage compartment 11 and the second storage compartment 13.


When the storage compartment is divided into the first storage compartment 11 and the second storage compartment 13, the first storage compartment 11 may be one of the refrigerating compartment and the freezing compartment, and the second storage compartment 13 may be the other of the refrigerating compartment and the freezing compartment. In this case, the first storage compartment 11 and the second storage compartment 13 may be separated from each other by means of the partition wall 15.


Alternatively, the first storage compartment 11 and the second storage compartment 13 may be formed by dividing one refrigerating compartment or freezing compartment into two compartments using the partition wall 15.


Each of the storage compartments 11 and 13 has to be provided with an open surface through which storage objects are taken out of the cabinet 1. Specifically, the first storage compartment 11 may communicate with the outside through a first open surface or a first opening 111, and may communicate with the outside through a second open surface or a second opening 131.


The first open surface 111 and the second open surface 131 may be configured to be opened and closed by the doors 20 and 30.


However, in the case in which the first storage compartment 11 and the second storage compartment 13 are isolated from each other in one refrigerating compartment or freezing compartment, the first storage compartment 11 and the second storage compartment 13 may be concurrently opened and closed by means of a single door.


The heat exchange unit may include a compressor configured to compress refrigerant, a condenser configured to cause the refrigerant discharged from the compressor to exchange heat with air outside the cabinet so as to condense the refrigerant, an expansion valve configured to reduce the pressure of the refrigerant discharged from the condenser and an evaporator configured to cause the refrigerant passed through the expansion valve to exchange heat with air in the storage compartments so as to evaporate the refrigerant. Since the evaporator absorbs heat from the air in the storage compartments, the air circulating in the storage compartments is cooled while passing through the evaporator. By virtue of this procedure, the heat exchange unit is able to control the temperature of the first storage compartment 11 and the second storage compartment 13 so as to be lower than the ambient temperature.


The partition wall 15, which divides the internal space of the refrigerator into the first storage compartment 11, that is, the first space, and the second storage compartment 13, that is, the second space, is provided with the receiving unit P. The receiving unit P may include the receiver 4, which is depressed downwards from the partition wall 15 so as to define a space for receiving storage objects, and the receiver door 5 configured to be moved in a direction parallel to the upper surface of the partition wall 15.


The receiver 4 may be formed in the partition wall 15 itself, or may be formed in a receiver body 3 coupled to the partition wall 15. When the receiver body 3 is coupled to an upper portion of the partition wall 15, the receiver body 3 may be made of a material different from that of the partition wall 15.


Any structure may be considered to be the partition wall 15 as long as the structure has a predetermined thickness (a length in the height direction of the cabinet, that is, a length in the z-axis direction) so as to divide the storage space into two spaces.


When the first storage compartment 11 is one of the refrigerating compartment and the freezing compartment and the second storage compartment 13 is the other of the refrigerating compartment and the freezing compartment, the partition wall 15 may include an insulator, and the receiver body 3 may define the upper surface of the partition wall 15.


However, if the first storage compartment 11 and the second storage 13 are spaces resulting from the division of a single refrigerating compartment or freezing compartment, the receiver body 3 may serve as the partition wall 15 because there is no necessity to provide the insulator.


Hereinafter, the case in which the receiver body 3 defines the upper surface of the partition wall 15 will be described for convenience of explanation.


As illustrated in FIG. 2, the receiver 4 may be a space that is formed by depressing the surface of the receiver body 3 toward the second storage compartment 13. Storage objects may be introduced into the receiver 4 through an introduction port or opening 41 formed in the upper surface of the receiver 4. The receiver 4 may be positioned at the front surface of the receiver body 3, which faces the door of the cabinet. In other words, the receiver 4 may be formed in the front side of the lower surface of the first storage compartment 11.


When the receiving unit P according to an embodiment of the present invention is provided at the partition wall 15, an additional component such as the above-described shelf 40 or the drawer 50 may further be provided above and close to the receiving unit P. In this case, if the gap between the receiving unit P and the additional component is small, a user may easily put a storage object into the receiver 4 or may easily take the storage object out of the receiver 4 only when the receiver 4 is positioned at a front side of the first storage compartment 11.


Specifically, the shelf 40 or the drawer 50 may be disposed above a rear side of the receiving unit P, rather than being disposed directly above the receiving unit P. A gap G may be defined between the receiving unit P and the shelf 40 or the drawer 50.


The receiver 4 may be composed of a receiving groove, which is integrally formed in the receiver body 3, or may be composed of the receiving groove and a tray, removably coupled to the receiving groove.


In the case in which the receiver 4 is composed of the receiving groove and the tray, it is possible for a user to take the tray out through the introduction port 41 and to wash the tray when it is a necessary to wash the receiver 4, thereby providing an effect of enabling the receiver 4 to be easily cleaned compared to the case in which the receiver 4 is composed only of the receiving groove.


When the receiver body 3 is configured to form the upper surface of the partition wall 15, there is no need to provide an additional space for mounting the receiver 4 because the receiver 4 is embedded in the partition wall 15.


Specifically, when the receiver body 3 forms the upper surface of the partition wall 15 and the receiver 4 is positioned in the partition wall 15, the receiving unit P according to an embodiment of the present invention may be mounted in the storage compartment 11 without reducing the sizes of the storage compartments 11 and 13, which have limited internal spaces. In other words, it is possible to increase the overall internal space.


That it is possible to mount the receiver 4 without reducing the internal space in the storage compartments 11 and 13 indicates that it is possible to add space for receiving storage objects without changing the volume or the number of the components (the drawer, the shelf or the like), which is mounted in the storage compartments 11 and 13 so as to receive storage objects. Accordingly, if the receiver body 3 is configured to form the upper surface of the partition wall 15 (i.e., the receiving unit is provided at the partition wall), there is an effect of maximizing the efficiency of storage.


The receiver door 5, which is intended to open and close the introduction port 41 formed in the receiver, may include a door body 51 capable of being moved along the surface of the receiver body 3. The door body 51 may be provided with a handle 53.


The receiver 4 is depressed downwards, and the introduction port 41 is formed in the upper surface of the receiver. Accordingly, introduction and removal of foodstuffs through the introduction port 41 is performed vertically. The movement of the receiver door for opening and closing the introduction port 41 is performed vertically. Accordingly, the direction of introduction of foodstuffs may be perpendicular to the direction of movement of the receiver door 5.


Generally, each of the storage compartments 11 and 13 of the refrigerator may be provided with the drawer 50, which is drawn out of the storage space so as to receive storage objects, or may be provided with the shelves 40, which are arranged in a vertical direction and are secured to the inside of the storage space so as to support storage objects.


Accordingly, the drawer or the shelf may be provided above the receiving unit P. Here, in the case in which the receiver door 5 is coupled to the receiver body 3 so as to be rotated toward the drawer or the shelf positioned thereabove, it is possible to put storage objects into the receiver 4 or to take the storage objects out of the receiver 4 only when the distance between the receiving unit P and the drawer or the shelf is larger than the radius of rotation of the receiver door 5.


If there is a need to change the height of the drawer or the shelf in order to mount the receiving unit P, this means that the storage space is reduced. Accordingly, the configuration, in which the introduction port 41 of the receiving unit P is opened and closed by means of the door body 51, which is capable of being moved in a direction parallel to the surface of the receiver body 3, is intended to minimize the internal space required to mount the receiver P.


An embodiment of the present invention may include a position holder or latch 6 capable of holding the state in which the door body 51 opens the introduction port 41. The embodiment of the present invention may include transfer units or closers 7a and 7b, which provide the door body 51 with force capable of moving the door body 51 in conjunction with or independently of the position holder 6 in the direction in which the introduction port 41 is closed.


The position holder 6 may include a coupling body 61 coupled to the door body 51, a coupling protrusion 63 provided at one of the receiver body 3 and the coupling body 61, and a coupling grab or coupling retainer 65 provided at the other of the receiver body 3 and the coupling body 61 so as to be removably engaged with the coupling protrusion 63. FIG. 3 illustrates an example in which the coupling protrusion 63 is provided at the coupling body 61 and the coupling grab 65 is secured to the receiver body 3.


As illustrated in FIG. 4, the coupling body 61 may be provided with a coupling portion 611 into which the door body 51 is fitted. Here, since the peripheral edge of the door body 51 is fitted into the coupling portion 611 and is thus secured to the coupling body 61, the coupling body 61 will be moved in conjunction with the door body 51.


The coupling portion 65 may be configured to be repeatedly engaged with or released from the coupling protrusion 63 whenever external force is applied to the coupling protrusion 63. FIG. 4B illustrates an example of the coupling portion 65 for realizing the above function.


As illustrated in FIG. 4B, the coupling grab 65 may include a first coupling grab body 651, secured to the receiver body 3, and a second coupling grab body 653, which is disposed in the first coupling grab body 651 so as to reciprocate therein and is removably engaged with the coupling protrusion 63.


The first coupling grab body 651 may include a fitting gate 651f into which the second coupling grab body 653 is fitted, a spring 651a for supplying elastic force to the second coupling grab body 653, and moving path sections 631b, 631c, 631d and 631e, which guide the movement of the second coupling grab body 653.


The spring 651a serves to push the second coupling grab body 653 toward the fitting gate 651f.


As illustrated in FIG. 3C, the moving path of the second coupling grab body 653 may include a first path section 651b, which extends toward the bottom surface of the first coupling grab body 651 (in a direction away from the fitting gate) from the fitting gate 651f, a second path section 651c, extending toward the fitting gate 651f from one end of the first path section, a third path section 651d, extending toward the bottom surface of the first body 631 from the second path section, and a fourth path section 651e, extending toward the fitting gate 651f from the third path section 651d and connected to the other end of the first path section 651b.


Here, the second coupling grab body 653 may include a bar 653a, rotatably coupled to the second coupling grab body via a shaft 653b, a protrusion 653c, provided at the bar so as to be inserted into the path sections 651b, 651c, 651d and 651e, and a first bar 653d and a second bar 653e, which are rotatably coupled to the second coupling grab body 653 and are exposed to the outside of the first coupling grab body 651 through the fitting gate 65 if.


Accordingly, when the door body 51 is moved in the posterior direction of the first space 11 (when the door body is moved so as to open the introduction port), the coupling protrusion 63 moves the second coupling grab body 653 toward the bottom surface of the first coupling grab body 651.


When the second coupling grab body 653 is pushed, the protrusion 653c is moved along the first path section 651b and the second path section 651c and is positioned at the connecting point (first point) between the second path section 651c and the third path section 651d, and the first bar 653d and the second bar 653e are rotated toward the coupling protrusion 63 while interfering with the fitting gate 651f. Consequently, when the protrusion 653c provided at the second coupling grab body is positioned at the first point, the coupling protrusion 63 is held on the second coupling grab body 653, and the door body 51 is maintained in the state of opening the introduction port 41.


In this state, when a user pushes the door body 51 toward the rear surface of the first space 11 once more, the coupling protrusion 63 pushes the second coupling grab body 653, and the protrusion 653c is thus moved to the connecting point (second point) between the fourth path section and the first path section 651b through the third path section 651d and the fourth path section 651e.


When the protrusion 653c provided at the second coupling grab body is positioned at the second point, the coupling protrusion 63 is released from the second coupling grab body 653. Accordingly, the door body 51 is moved in the forward direction of the first space 11 by means of the transfer unit 7a and 7b, thereby closing the introduction port 41.


Each of the transfer units 7a and 7b may include an elastic-force provider or elastic-spring 75 configured to provide the door body 51 with restoring force (force capable of moving the door body toward the introduction port when the external force applied to the door body is released) when the door body 51 is moved so as to open the receiver 4. Each of the transfer units 7a and 7b may include a speed controller 76 for controlling the moving speed of the door body 51 when the door body 51 is moved in conjunction with or independently of the elastic-force provider 75 so as to close the receiver 4.


The elastic-force provider 75 and the speed controller 76 may be configured to directly connect the door body 51 to the body 3, or may be configured to connect the support 71 to the slider 77 which is moved together with the door body 51, as illustrated in FIG. 5.


The support 71, which is provided in a direction parallel to the direction of movement of the door body 51 so as to provide the moving path of the slider 77, may be secured to the receiver body 3.


The slider 77, which is reciprocated in the slider recess 31 formed in the body 3 in a direction parallel to the direction of movement of the door body 51, may include a through hole 771 into which the support 71 is inserted, and a door coupler 773 coupled to the door body 51.


The elastic-force provider 75 may be composed of a tensile spring, which is connected to both the support 71 and the slider 77 so as to provide restoring force capable of moving the door body 51 so as to close the receiver 4.


Alternatively, the elastic-force provider 75 may be composed of a compression spring. The elastic-force provider 75, which is composed of the compression spring, has to be configured to push the slider 77 toward the receiver 4, as illustrated in FIG. 5.


Accordingly, the door body 51, which has been moved so as to open the receiver 4, is moved toward the first opening 111 so as to close the receiver 4 by means of the elastic-force provider 75 when the coupling protrusion 63 is released from the coupling grab 65.


If the restoring force provided to the door body 51 by the elastic-force provider 75 is excessive, there are risks of the door body 51 being damaged due to collision with the receiver body 3 and of a user's hand colliding with the door body 51. The speed controller 76 according to an embodiment of the present invention is able to solve the above-described problems by reducing the speed of movement of the door body 51 when the door body 51 is moved so as to close the introduction port 41.


As illustrated in FIG. 5, the speed controller 76 may include a cylinder 761 secured to the support 71, a piston, which is disposed at one end thereof in the cylinder and is connected at the free end thereof to the slider 77, and a head 765 secured to the one end of the piston and disposed in the cylinder 761.


The speed controller 76 may be configured to increase the extension distance of the piston 763 as the door body 51 is moved so as to open the introduction port 41 (as the coupling protrusion 63 is moved toward the coupling grab 65).


The speed controller 76, which has the above structure, may reduce the moving speed of the door body 51 when the door body 51 is moved so as to open the introduction port 41 and the door body 51 is moved so as to close the introduction port 41.


As illustrated in FIG. 3, the transfer units, which have the above structure, may be respectively provided at opposite lateral side edges of the door body 51. The reason for this is to prevent the occurrence of a problem in which the movement of the door body 51 is stopped because the distance of movement of one of opposite lateral ends of the door body 51, which are parallel to the direction of movement of the receiver door 5, is different from the distance of movement of the other of the opposite lateral ends of the door body 51.


Assuming that a single transfer unit is provided so as to support the center of the door body 51, when a user pushes the door body 51 in the rearward direction of the first storage compartment 11 at a point deviating from the center of the door body 51, the moving distance of the left lateral end L may be different from the moving distance of the right lateral end R. If the moving distances of the left and right lateral ends are different from each other, a problem in which the door 51 cannot be moved or in which a lot of force is required to move the door body 51 may occur.


However, when the transfer units 7a and 7b are respectively provided at the left lateral end L and the right lateral end R of the door body 51, it is possible to prevent the above problem in which the door body 51 is inclined when a user pushes the door body at a point deviating from the center of the door body 51.


In order to prevent the door body 51 from being slanted, an embodiment of the present invention may further include a guide 8 for guiding the movement of the door body 51.


As illustrated in FIG. 3, the guide 8 may further include at least one of first guides 811 and 813, disposed between the two transfer units 7a and 7b, and second guides 842 and 843, which are respectively provided at opposite lateral ends L and R of the door body 51, which is parallel to the direction of movement of the receiver door 5. The guide 8 may be provided at the center of the receiver door 5 in a lateral direction.


The transfer units 7a and 7b are configured to generate elastic force and/or damping force when the force applied to the receiver door 5 by a user is released. In other words, the transfer units 7a and 7b are configured not only to guide movement of the receiver door 5 through the transfer units but also to provide elastic force and/or damping force to the receiver door 5. However, the guide 8 may be configure so as not to provide elastic force or damping force to the receiver door 5. In other words, the guide 8 may be configured to guide the anteroposterior movement of the transfer-unit door 50 at the center of the transfer-unit door 5 in a lateral direction.


The first guide may include a roller 811, rotatably provided in the door body 51, and a roller-receiving groove 813 provided in the receiver body 3 so as to receive the roller.


The roller 811 may be disposed at any location on the door body 51, as long as the roller is disposed between the pair of transfer units 7a and 7b. FIG. 3 illustrates an example in which the roller (first roller) 811 is positioned at the center of the door body 51.


In this case, the first roller 811 may be rotatably secured to the coupling body 61 positioned at the center of the door body 51, and the roller-receiving groove 813 may be formed by depressing the surface of the receiver body 3.


Each of the second guides may include a roller (second roller) 841, rotatably secured to opposite lateral ends L and R of the door body 51, which are parallel to the direction of movement of the receiver door 5, and a support wall 843 provided at one of opposite lateral ends, which is parallel to the direction of movement of the receiver door 5, so as to support the second roller 841.


The support wall may be composed of a rib projecting from the peripheral edge of the receiver body 3. The support wall 843 may further include a cover defining a space for receiving the peripheral edge portion of the door body 51.


Since the cover 845 is made of a plate extending toward the door body 51 from the support wall 843 so as to support the front peripheral edge of the door body 51, the present invention is able to prevent the door body 51 from being separated from the receiver body 3 by virtue of the cover 845.



FIGS. 6 to 8 illustrate another embodiment of the transfer unit according to an embodiment of the present invention. Each of the transfer units 7a and 7b according to this embodiment may include a support 71 extending in a direction parallel to the direction of movement of the door body 51, a transfer space S, which is parallel to the direction of movement of the door body 51, a first slider 772, which is movable in the transfer space and is connected to the free end 7633 of the piston, and a second slider 778, which is connected to the door body 51 and is secured to one end of the elastic-force provider 75.


The second slider 778 is characterized by being separated from the first slider 772 depending on whether the free end 7633 of the piston passes over a predetermined reference point P2 (see FIG. 8).


The support 71 may include a base 711, secured in a slider recess 31 provided in one of opposite lateral ends the receiver body and secured to the body 3 so as to be parallel to the direction of movement of the door body 51, and a first side wall 712 and a second side wall 713, which are provided at opposite lateral ends of the base 711 parallel to the direction of movement of the door body 31 (the x-axis direction). Here, the transfer space S is defined by the base 711, the first side wall 712 and the second side wall 713.


The transfer space S is provided therein with a first support 716 and a second support 717, which are spaced apart from each other by a predetermined distance so as to provide the moving path of the first slider 772. Here, the first slider 772 is positioned between the first support 716 and the second support 717, and is connected to the free end 7633 of the piston via a piston coupler 776.


As illustrated in FIG. 7, the first slider 772 may include a mount portion 777 in which the second slider 778 is received. The mount portion 777 may be defined by a first stopper 777a and a second stopper 777b, which are spaced apart from each other so as to receive the second slider 778.


The first stopper 777a may be defined as a stopper, which is positioned in a direction in which the second slider 778 is separated from the first slider 772, and the second stopper 777b may be defined as a stopper closer to the free end 7633 of the piston.


The second slider 778 may include a door coupler 778b coupled to the door body 51 and a spring coupler 778a secured to an end of the elastic-force provider 75.


In the transfer units 7a and 7b having the above-described structure, the second slider 778 may be separated from the first slider 772 by means of height controllers 716a, 716b, 717a, 717b, 718a and 718b.


As illustrated in FIGS. 6 and 8, the height controllers may include a first projection 718a (see FIG. 8), which projects from the first slider 772 so as to cause the first slider 772 to be supported by the first support 716, a second projection 718b, which projects from the first slider 772 so as to cause the first slider to be supported by the second support 717, a first receiving groove 716b formed at a position lower than the first support 716 so as to receive the first projection 718a therein, a second receiving groove 717b formed at a position lower than the second support 717 so as to receive the second projection 718b therein, a first sloped portion 716a inclined downwards toward the first receiving groove from the first support 716, and a second sloped portion 717a inclined downwards toward the second receiving groove 717b from the second support 717.


As illustrated in FIG. 8, when the free end 7633 of the piston reaches the reference point P2, the height controllers move the first projection 718a and the second projection 718b to the first receiving groove 716b and the second receiving groove 717b, thereby lowering the first stopper 777a to a position lower than the first support 716 and the second support 717.


Since the first stopper 777a is the stopper that is positioned in the direction in which the second slider 778 is separated from the first slider 772, when the first stopper 777a is moved to a position lower than the first support 716 and the second support 717, the second slider 778 is allowed to be separated from the mount portion 777 of the first slider 772.


Accordingly, when a user pushes the door body 51 in the posterior direction of the first space 11 (in the negative x-axis direction) such that the free end 7633 of the piston passes over the reference point P2, the door body 51 is able to move together with the second slider 778 until the coupling protrusion 63 is coupled to the coupling grab 65.


When the coupling protrusion 63 is separated from the coupling grab 65, the door body 51 is moved toward the first slider 772 by means of the second slider 778, which is connected to the elastic-force provider 75. At this time, the second slider 778 collides with the second stopper 777b provided at the first slider. Upon collision of the second slider with the second stopper, the first projection 718a and the second projection 718b are taken out of the first receiving groove 716b and the second receiving groove 717b.


When the first projection 718a and the second projection 718b are taken out of the first receiving groove 716b and the second receiving groove 717b, the second slider moves together with the first slider toward the introduction port 41. At this time, since the first slider 772 is connected to the speed controller 76, an excessive increase in the moving speed of the door body 51 is prevented.


The reference point P2 may be set to be a point in the moving range P1 of the free end 7633 of the piston. FIG. 8 illustrates an example in which the reference point P2 is set to be the limiting point of the moving range of the free end 7633 of the piston.


The reference point P2 may be set to be the position of the free end 7633 of the piston that is located between the point at which the door body 51 begins to close the introduction port 41 and the point at which the door body 51 closes the introduction port 41 by 50%.


Assuming that the drawer or the shelf is positioned above the receiving unit P, it is advantageous for the door body 51 to be quickly moved to the reference point in terms of rapid closing of the introduction port 41. The reason for this is because, even when the door body 51 is quickly moved to the reference point, none of the above-mentioned problems caused by the high speed of the door body 51 occur.


For this reason, the reference point P2 may be set to be the position of the free end 7633 of the piston that is located between the point at which the door body 51 closes the introduction port 41 by 50% or more and the point at which the door body 51 closes the introduction port 41 by 90%.


As illustrated in FIG. 7, each of the transfer units 7a and 7b according to this embodiment may further include slider guides 791, 793, 795 and 797 configured to guide the movement of the first slider 772.


Specifically, each of the slider guides may include a first transfer groove 791, which is formed in the first side wall 712 of the support in the direction of movement of the door body 51, a second transfer groove 793, which is formed in the second side wall 713 in the direction of movement of the door body 51, a first protrusion 795, which projects from the first slider 772 and is fitted into the first transfer groove 791, and a second protrusion 797, which projects from the first slider 772 and is fitted into the second transfer groove 793.


In the above-described embodiments, the position holder 6 is positioned behind the receiver door 5. A portion of the position holder 6 may be positioned below the drawer 50 through the gap G. In other words, a portion of the position holder 6 may be positioned below the drawer 50 even when the receiver door 5 closes the introduction port 41.


When the receiver door 5 opens the introduction port 41, the receiver door 50 may be further moved through the gap G.


Accordingly, the position holder may be a structure, all of which is visible to a user or only a portion of which is visible to a user. When a user intuitively pushes the receiver door 5 rearwards, the movement of the receiver door 5 may be restricted at a certain moment. Subsequently, when a user intuitively pushes the receiver door 5 rearwards again, the movement of the receiver door 5 may be restricted.


By virtue of these characteristics, it is possible to prevent damage to the position holder 6. Furthermore, it is possible to prevent a reduction in storage space and deterioration of design due to the presence of the position holder 6. Particularly, when the receiver door 5 is made of a transparent material, it is possible to prevent deterioration in design of the receiver door 5 due to the presence of the position holder 6.


In the above embodiments, the transfer units 7a and 7b may be provided at opposite lateral ends of the receiver door, and may be disposed below the receiver door. Accordingly, it is possible to prevent a reduction in the amount of storage space, deterioration in the design of the storage compartment, and deterioration in the design of the receiver door 5 by virtue of the transfer units.


In the above embodiments, the receiver door 5 may be easily removed from the receiving unit P. Basically, the receiver door 5 may come into contact with the upper surface of the partition wall due to its own weight, and may be configured to have a horizontal plate shape so as to be moved horizontally.


The transfer units 7a and 7b and the position holder 6 may be removably coupled to the rear end of the receiver door 5.


Specifically, as illustrated in FIG. 2, each of the transfer units 7a and 7b may be provided with the door coupler 773. The position holder 6 may be provided with the coupling body 61. The door coupler and the coupling body may be configured to have a groove shape so as to receive the receiver door to the rear from the front. Accordingly, as the receiver door is moved rearwards, the receiver door pushes the transfer units and the position holder rearwards. Similarly, as the transfer units and the position holder are moved forwards, the receiver door is moved forwards.


When a user moves the receiver door vertically in the state of grasping the front portion of the receiver door and then pulls the receiver door forwards, the receiver door can be easily separated from the door coupler and the coupling body. Similarly, the receiver door can be easily coupled to the door coupler and the coupling body through the reverse manipulation.


Accordingly, a user can separate the receiver door 5 and can perform cleaning of the receiver door 5 and the receiver 4.


The present invention may be embodied so as to have various modifications, and the scope of rights thereof is not limited to the above embodiments. Accordingly, as long as the modifications thereof include the components disclosed in claims, it should be understood that such modifications are considered to fall within the scope of rights of the present invention.
