Referring to FIGS. 1 through 6, the refrigerator may include, for example, a body 10, a storage compartment 20 provided inside the body 10 so as to be open at a front surface thereof, a door 30 including a refrigerating compartment door 31 having an opening 31a and configured to open and close the storage compartment 20, and an outer door 35 to open and close the opening 31a provided at the refrigerating compartment door 31, an upper hinge 40 and a lower hinge 50 allowing the door 30 to be rotatably coupled to the body 10, and a sliding device 100 allowing a plurality of door guards 37 provided at the opening 31a of the refrigerating compartment door 31, to be inserted and withdrawn in a sliding manner. In an embodiment, the plurality of door guards 37 may be alternatively embodied as a plurality of storage containers or a plurality of door bins.

The body 10 includes an inner case (not shown) forming the storage compartment 20 and an outer case (not shown) forming the external appearance, and includes a cool air supply device (not shown) to supply the storage compartment 20 with cool air.

The cool air supply device includes a compressor, a condenser, an expansion valve, an evaporator, a blower fan, and a cool air duct, and heat insulation material (not shown), which is blown into a space between the inner case and the outer case to prevent cool air of the storage compartment 20 from leaking.

The body 10 is provided at a lower rear side thereof with a machine room (not shown) in which the compressor to compress refrigerant and the condenser to condense the compressed refrigerant are installed.

The storage compartment 20 is divided into left and right sides by a partition wall 11 to form a refrigerating compartment 21 at the right side of the body 10, and a freezing compartment 23 at the left side of the body 10.

A plurality of shelves 25 are provided at the refrigerating compartment 21 to divide the refrigerating compartment 21 into a plurality of spaces.

The refrigerating compartment 21 and the freezing compartment 23 are opened and closed by the refrigerating compartment door 31 and a freezing compartment door 33, respectively, which are pivotably coupled to the body 10, and the upper hinge 40 and the lower hinge 50 are coupled to an upper portion and a lower portion of the body 10, respectively, such that the refrigerating compartment door 31 and the freezing compartment door 33 are rotatably coupled to the body 10.

The refrigerating compartment door 31 is formed with the opening 31a, and the plurality of door guards 37 are provided at opening 31a.

The plurality of door guards 37 are provided so as to be alternatively inserted and withdrawn in a sliding manner by the sliding device 100, and the configuration of the sliding device 100 will be described later. For example, the plurality of door guards 37 may be pulled out or withdrawn away from the refrigerating compartment 21 and then may be inserted or pushed back into the refrigerating compartment 21 in a sliding manner by the sliding device 100, in order to more readily access food items stored using the door guards 37.

A refrigerating compartment door grip 31c and a freezing compartment door grip 33a are provided at the refrigerating compartment door 31 and the freezing compartment door 33, respectively. The grips 31c and 33a may be gripped by a user to open the refrigerating compartment door 31 and the freezing compartment door 33, respectively.

The opening 31a provided at the refrigerating compartment door 31 is open and closed by the outer door 35, and for the sake of convenience, the refrigerating compartment door 31 may be referred to as an inner door.

Separately from the refrigerating compartment door 31 and the freezing compartment door 33, the outer door 35 is also provided with an outer door grip 35a that may be gripped by a user to open the outer door 35.

Since the opening 31a provided at the inner door 31 has a size corresponding to the refrigerating compartment 21, the plurality of door guards 37 provided over the entire area of the refrigerating compartment 21, rather than a part of the refrigerating compartment 21, may be accessed or used by opening the outer door 35.

The upper hinge 40 and the lower hinge 50 are coupled at the upper portion and the lower portion of the body 10, respectively, such that each of the refrigerating compartment door 31 and the freezing compartment door 33 is rotatably coupled to the body 10, and each of the upper hinge 40 and the lower hinge 50 may be coupled to the outer door 35 and the refrigerating compartment door 31, which represents the inner door and on which the outer door 35 is provided.

Referring to FIGS. 5 to 8, the door guard 37 provided at the opening 31a in a plurality of units thereof are inserted and withdrawn in a sliding manner by the sliding device 100.

Although some of the plurality of door guards 37 are illustrated as fixed at both side walls 31b of the opening 31a and others of the plurality of door guards 37 are illustrated as being slidable by the sliding device 100 in FIGS. 5 to 8, all of the plurality of door guards 37 may be provided so as to be fixed to both side walls 31b or all of the plurality of door guards 37 may be provided so as to be slidable by the sliding device 100, or any combination of fixed or slidable door guards may be provided.

In addition, although the door guard 37 fixed to both side walls 31b of the opening 31a is illustrated to have a shape different from that of the door guard 37 slid by the sliding device 100, both of the door guards 37 may have the same shape, or the shapes of the door guards 37 may switched.

The sliding device 100 includes a guide rail 150 supported by both side walls 31b of the opening 31a of the inner door 31 to allow the door guard 37 to be inserted and withdrawn in a sliding manner, a case 110 coupled to a lower portion of the door guard 37, a slide unit 120 coupled to the case 110 so as to be slid along the guide rail 150, an elastic unit 130 to transmit a tensile force in a direction of the door guard 37 being inserted, and an automatic closing unit 140 configured to allow the elastic unit 130 to transmit a tensile force to the door guard 37 such that the door guard 37 is automatically inserted.

The guide rail 150 is supported by both side walls 31b of the opening 31a of the inner door 31 to guide the door guard 37 to be inserted and withdrawn in a sliding manner.

The guide rail 150 includes a support part 151 supported by both side walls 31b of the opening 31a, and a rail part 153 provided to extend from the support part 151 toward an interior of the refrigerating compartment 21 to guide the door guard 37.

Although not shown, in order to firmly fix the support part 151, a reinforcing member may be provided at both side walls 31b of the opening 31a such that the support part 151 is fixed to the reinforcing member.

The rail part 153 includes a first rail part 155 provided adjacent to a left side wall of side walls 31b, and a second rail part 157 provided adjacent to a right side wall of the side walls 31b.

The second rail part 157 is provided with a locking part 157a which protrudes upward and with which a hook part 135b of a rotator 135 of the elastic unit 130 may be locked and released from being locked. A more detailed description of the locking part 157a is provided later.

The case 110 is coupled to the lower portion of the door guard 37, and includes a second rotating shaft 111 and a third rotating shaft 113, which are coupled to a second rotation hole 141a and a third rotation hole 143a, respectively, which are formed at a first lever 141 and a second lever 143 of the automatic closing unit 140, respectively, and an opening 115 provided adjacent to the second rotating shaft 111.

The second rotation hole 141a formed through the first lever 141 is rotatably coupled to the second rotating shaft 111, and the third rotation hole 143a formed through the second lever 143 is rotatably coupled to the third rotating shaft 113.

The opening 115 is provided adjacent to the second rotating shaft 111 such that the first lever 141 protrudes to the outside when the door guard 37 is withdrawn or in a state of being partially withdrawn, and thus when the outer door 35 is closed, the first lever 141 makes contact with the outer door 35.

The slide unit 120 includes a first sliding part 121 coupled to a lower portion of the case 110 to correspond to the first rail part 155, a second sliding part 122 coupled to a lower portion of the case 110 to correspond to the second rail part 157, first slide rails 126 coupled to upper portions of the first rail part 155 and the second rail part 157, respectively, and second slide rails 127 coupled to lower portions of the first sliding part 121 and the second sliding part 122, respectively, so as to be slid along the first slide rail 126.

The first slide rails 126 are fixedly coupled to the upper portions of the first rail part 155 and the second rail part 157, respectively, and allow the second slide rails 127 fixedly coupled to the lower portions of the first sliding part 121 and the second sliding part 122, respectively, to be moved therealong such that the door guard 36 coupled to the case 110 is slidably moved in the front and back direction.

The second sliding part 122 includes a fixing part 123 to which one end of the elastic member 131 of the elastic unit 130 is fixed, an accommodation part 124 in which the elastic unit 131 is accommodated, and a guide rail 125 to guide a protrusion part 135c provided on the rotator 135 of the elastic unit 130.

The guide rail 125 includes a straight line path 125a along which the protrusion part 135c provided on the rotator 135 performs a straight linear motion in a front and back direction, and a locking groove 125b provided at an end portion of the straight line path 125a so as to allow the protrusion part 135c, while performing a straight linear motion on the straight line path 125a, to be locked with the locking groove 125b as the rotator 135 rotates on a first rotating shaft 135a.

The elastic member 131 having the one end fixed to the fixing part 123 generates a tensile force with the other end moving in a direction away from the fixing part 123. A more detailed description thereof will be provided later.

The elastic unit 130 includes the elastic member 131 having one end fixed to the second sliding part 122 to generate a tensile force, a connection member 133 to which the other end of the elastic member 131 is coupled, and the rotator 135 connected to the connection member 133 so as to allow the connection member 133 to move in a front and back direction and configured to move while being guided by the guide rail 125.

In an embodiment, the elastic member 131 has one end fixed to the fixing part 123 of the second sliding part 122 and has the other end coupled to the connection member 133. As the connection member 133 moves away from the fixing part 123, the elastic member 131 accumulates a tensile force, and the accumulated tensile force acts in an insertion direction of the door guard 37 by the automatic closing unit 140 that operates in contact with the outer door 35, so that the door guard 37 is automatically closed.

The connection member 133 includes a coupling part 133a, to which the other end of the elastic member 131 is coupled, and a first rotation hole 133b coupled to the rotator 135.

The rotator 135 includes the first rotating shaft 135a rotatably coupled to the first rotation hole 133b formed through the connection member 133, the hook part 135b locked with and released from the locking part 157a provided on the second rail part 157, and the protrusion part 135c protruding from a lower side of the rotator 135.

The hook part 135b is locked with the locking part 157a during a process of withdrawing the door guard 37. As the hook part 135b is locked with the locking part 157a, the other end of the elastic member 131, coupled to the connection member 133, is fixed and the one end of the elastic member 131 moves together with the door guard 37 in the direction in which the door guard 37 is being withdrawn, so that the elastic member 131 generates a tensile force.

In order for the elastic member 131 to generate a tensile force, the protrusion part 135c moves along the straight line path 125a of the guide rail 125, and if the withdrawing of the door guard 37 is completed, the rotator 135 rotates on the first rotating shaft 135a clockwise and the protrusion part 135c is locked with the locking groove 125b, so that the elastic member 131 maintains the tensile force.

The automatic closing unit 140 includes the first lever 141 rotatably coupled to the case 110 to make contact with the outer door 35, the second lever 143 rotatably coupled to the case 110 to make contact with the rotator 135, and a link 145 connecting the first lever 141 to the second lever 142.

The automatic closing unit 140 is coupled to a right portion of the case 110 adjacent to a portion of the inner door 31 at which the upper hinge 40 and the lower hinge 50 are provided, such that the automatic closing unit 140 makes contact with the outer door 35 when the outer door 35 is closed.

The first lever 141 of the door 30 having the upper hinge 40 and the lower hinge 50, which are configured to rotatably couple the door 30 to the body 10, is formed with the second rotation hole 141a rotatably coupled to the second rotating shaft 111 of the case 110, and the second lever 143 is formed with the third rotation hole 143a rotatably coupled to the third rotating shaft 113.

In a state in which the door guard 37 is being pulled out or withdrawn, the first lever 141 partially protrudes to the outside through the opening 114 formed through the case 110, and if the outer door 35 is closed while the door guard 37 is withdrawn, the first lever 141 protruding to the outside comes into contact with the outer door 35 before the door guard 37 comes into contact with the outer door 35.

Upon contact with the outer door 35, the first lever 141 rotates clockwise, and then is inserted into the case 110, and according to the rotation of the first lever 141, the second lever 143 connected to the first lever 141 through the link 145 rotates counterclockwise to operate the elastic unit 130, so that the door guard 37 is automatically inserted by the tensile force of the elastic member 131.

Hereinafter, a process of inserting and withdrawing the door guard 37 with the sliding device 100 will be described with reference to FIG. 5 and FIGS. 8 to 12.

Referring to FIG. 8, in a state in which the door guard 37 is inserted, the first lever 141 of the automatic closing unit 140 is accommodated in the case 110.

If the inserted door guard 37 is withdrawn as shown in FIG. 9, the case 110 coupled to the door guard 37 also moves together with the door guard 37 in a direction of the door guard 37 being withdrawn, and the second sliding part 122 of the sliding unit 120 coupled to the case 110 also moves in the direction of the door guard 37 being withdrawn.

If the second sliding part 122 moves in the direction of the door guard 37 being withdrawn, the elastic unit 130 fixed to the fixing part 123 of the second sliding part 122 moves together with the second sliding part 122 in the direction of the door guard 37 being withdrawn.

If the door guard 37 is partially withdrawn, the hook part 135b provided on the rotator 135 of the elastic unit 130 is locked with the locking part 157a provided on the second rail part 157.

As the hook part 135b is locked with the locking part 157a, the rotator 135, the connection member 133 connected to the rotator 135, and the other end of the elastic member 131 coupled to the connection member 133 are fixed, and the one end of the elastic member 131 coupled to the fixing part 123 of the second sliding part 122 moves together with the second sliding part 122 to generate a tensile force at the elastic member 131.

While the one end of the elastic member 131 is moving together with the second sliding part 122 in the direction of the door guard 37 being withdrawn, the protrusion part 135c of the rotator 135 is guided along the guide rail 125 provided on the second sliding part 122 so as to be moved in a direction opposite to the direction of the door guard 37, which is being withdrawn, with respect to the guide rail 125.

If the withdrawing of the door guard 37 is completed as shown in FIG. 10, the protrusion part 135c, while being guided along the straight line path 125a of the guide rail 125, is guided to the locking groove 125b provided at an end portion of the straight line path 125a.

Since the rotator 135 is coupled to the connection member 133 so as to rotate on the first rotating shaft 135a, when the rotator 135 rotates clockwise, the protrusion part 135c is guided to the locking groove 125b.

The protrusion part 135c guided to the locking groove 125b maintains a locked state with the locking groove 125b to maintain the tensile force of the elastic member 131, and the rotator 135, which rotates clockwise, making contact with the second lever 143 pushes the second lever 143 such that the second lever 143 rotates clockwise on the third rotating shaft 113.

If the second lever 143 rotates clockwise, the first lever 141 connected to the second lever 143 through the link 145 rotates counterclockwise on the second rotating shaft 111, so that a part of the first lever 141 protrudes through the opening 115 formed through the case 110.

When the withdrawing of the door guard 37 has been completed, as shown in FIGS. 5 and 10, a part of the first lever 141 of the automatic closing unit 140 protrudes to the outside through the opening 115 formed through the case 110.

When the outer door 35 is closed while the door guard 37 is withdrawn, as shown in FIG. 11, the first lever 141 making contact with the outer door 35 rotates on the second rotating shaft 111 clockwise, and the second lever 143 connected to the first lever 141 through the link 145 rotates counterclockwise on the third rotating shaft 113.

The second lever 143 rotating counterclockwise pushes the rotator 135, the protrusion part 135c of which is locked with the locking groove 125b, and thus the rotator 135 rotates counterclockwise on the first rotating shaft 135a.

As the rotator 135 rotates counterclockwise, the protrusion part 135c locked with the locking groove 125b escapes from the locking groove 125b and moves along the straight line path 125a.

As the protrusion part 135c moves along the straight line path 125a, as shown in FIG. 12, the tensile force maintained by the elastic member 131 acts in a direction of the door guard 37 being inserted, and is transmitted to the door guard 37.

Since the door guard 37 having received the tensile force of the elastic member 131 is automatically inserted back into the refrigerating compartment 21 without having to be manually pushed, as described above, the shortcoming in which the outer door 35 fails to completely close when the outer door 35 is being closed while the door guard 37 is withdrawn is overcome, and the door guard 37 is prevented from breaking.

Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
