DETAILED DESCRIPTION OF EMBODIMENTS [0034] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures. [0035] Referring to FIGS. 1 through 2, a Kimchi refrigerator according to an embodiment of the present invention includes: a main body 10 having the storage compartment 13 and an opening 14 formed at the front of the storage compartment 13, a door assembly 20 accommodated in the storage compartment 13 of the main body 10 to slidably open/close the opening 14 and a door holding device 30 to hold a sliding of the door assembly 20 when the door assembly 20 slidably opens/closes the opening 14. [0036] The main body 10 includes an outer casing 11 forming an external appearance and an inner casing 12 provided inside the outer casing 11 with a foaming material layer between the outer casing 11 and forming the storage compartment 13 to accommodate the door assembly 20. [0037] Guide rails 15 are provided at opposite sides of the inner casing 12 corresponding to a pair of sliders 22 (to be described later) to slide the door assembly 20 through the opening 14. [0038] The door assembly 20 includes a door 21 provided at a front of the door assembly 20, the pair of sliders 22 provided at opposite sides of the door 21 to slide the door assembly 20 into/out of the storage compartment 13 and a pair of mounting brackets 23 each connected to inside each of the pair of the sliders to accommodate a container 24. [0039] The slider 22 slides along the guide rail 15 provided at the opposite sides of the inner casing 12 and includes a roller having a plurality of rolling bowls, thereby rolling-contacting with the guide rail 15. [0040] The door holding device 30 includes a hooking part 31 provided on one of the door assembly 20 and the main body 10 and a hook 32 that is provided on the other one of the door assembly 20 and the main body 10 and rotates with respect to the hooking part 31 to be hooked with/released from the hooking part 31. Here, the door holding device 30 includes a hinge shaft 33 to rotatably support the hook 32. [0041] According a first embodiment of the present invention, the holing part 31 is provided on the mounting bracket 23 of the door assembly 20 and moves as a single body with the door assembly 20 when the door 21 opens/closes the opening 14. [0042] The hook 32 is provided on opposite sides of the inner casing and rotates with respect to the hinge shaft 33 between a first position at which the hook is hooked with the hooking part 31 when the door assembly 20 closes the opening 14 and a second position at which the hook is released from the hooking part 31 when the door assembly 20 opens the opening 14. As shown in FIG. 2, the hook 32 includes an accommodating part 37 having an accommodating groove 39 to accommodate the hooking part 31 and a rotation supporting part 38 extending from the accommodating part 37 and having a hinge shaft accommodating hole 42 to accommodate the hinge shaft 33. [0043] The accommodating part 37 is of an approximate U shape and includes a first contacting part 40 and a second contacting part 41 oppositely positioned with respect to the accommodating groove 39. [0044] The first contacting part 40 is positioned at a front side of the accommodating groove 39 and shorter than the second contacting part 41. Thus, when the hook 32 is moved from the first position to the second position by the hooking part 31, the hooking part 31 pushes an inner surface of the first contacting part 40 and the pushed hook 32 rotates with respect to the hinge shaft 33. [0045] The second contacting part 41 is positioned at a rear side of the accommodating groove 39 and longer than the first contacting part 40. Thus, when the hook 32 is moved from the second position to the first position by the hooking part 31, the hook 31 pushes an upper part of the second contacting part 41 and the pushed hook 32 rotates with respect to the hinge shaft 33. [0046] A circumferential surface of the rotation supporting part 38 are formed with a first roller contacting part 43, a second roller contacting part 44 and a third roller contacting part 45 to contact with a roller 35 (to be described later). [0047] The first roller contacting part 43 is grooved from the circumferential surface of the rotation supporting part 38 to contact with the roller 35 when the door assembly 20 closes the opening 14. [0048] The second roller contacting part 44 is grooved under the first roller contacting part 43 to contact with the roller 35 when the door assembly 20 opens the opening 14. When the door assembly 20 opens the opening 14, the hook 32 moves from the first position to the second position and the roller 35 passes a first rolling guide 46 and contacts with the second roller contacting part 44 to support the hook 32. [0049] The third roller contacting part 45 is grooved on the first roller contacting part 43 to contacts with the roller 35 when the roller 32 further rotates backwardly from the first position. That is, if the door assembly 20 closes the opening 14 when the door assembly 20 opens the opening 14 but the roller 35 still contacts with the first roller contacting part 43, the hook 32 rotates with respect to the hooking part 31 backwardly, so that the roller 35 passes the second rolling guide 47 to contact with the third roller contacting part 45. [0050] The door holding device 30 includes an elastic member 34 to elastically rotate the hook 32. [0051] The elastic member 34 may be a coil spring provided at the rear of the rotation supporting part 38. The coil spring may be a compression spring that can be pressed by a pressure by the hook 32 when the hook 32 rotates. However, by way of non-limiting examples, the elastic member 34 may also be a plate spring or be made of rubber. [0052] Then, the hook 32 can elastically rotate and hold the sliding of the door assembly 20 by being hooked with/released from the hooking part 31. [0053] Further, the door holding device 30 further includes the roller 35 to rolling-contact with a part of the hook 32. The door holding device 30 further includes a supporting brackets 36 provided on opposite sides of the main body 10 forming the storage compartment 13 to rotatably support the hook 32. [0054] The roller 35 positioned between the hook 32 and the elastic member 34 includes a roller shaft 48 on a side thereof. By way of non-limiting example, the roller 35 may be of a cylinder shape and made of material having a small coefficient of elasticity to smoothly rolling-contact with the hook 32. Especially, the roller 35 may be injection molded with polyacetal. Thus, the first, second and third roller contacting parts 43, 44 and 45 to rolling-contact with the roller 35 may be a shape of an arc corresponding to the shape of the roller 35. [0055] The roller shaft 48 is accommodated in a roller shaft accommodating slit 49 (to be described later) formed on a surface of the supporting bracket 36 and movable in the roller shaft accommodating hole 49 according to a rotation of the hook 32. [0056] The supporting bracket 36 is of an approximately U shape. A surface of the supporting bracket 36 is formed with a connecting hole 50 to connect the supporting bracket 36 to the inner casing 12, a hinge hole 51 to accommodate the hinge shaft 33 and the roller shaft accommodating slit 49 to accommodate the roller shaft 48. The supporting bracket 36 includes a supporting part 52 in the vicinity of the roller 35 to accommodate a part of the elastic member 34 and support the elastic member 34. [0057] A description of an operation of the door holding device 30 of the Kimchi refrigerator 1 according to the first embodiment of the present invention with a configuration described above follows. [0058] As shown in FIG. 3, when the door 21 closes the opening 14 (shown in FIG. 1), the hooking part 31 is accommodated in the accommodating part 37 (shown in FIG. 2) of the hook 32 (shown in FIG. 1) and the roller contacts to the first roller contacting part 43. [0059] As shown in FIG. 4, if a user pulls the door 21 forwardly to draw out the door 21, the hooking part 31 moves forwardly corresponding to a moving direction of the door assembly 20 and the hook 32 rotates with respect to the hinge shaft 33 to be release from the hooking part 31. At this time, the hook 32 pushes the roller 35 and presses the elastic member 34 until the roller 35 passes the first rolling guide 46 and contacts to the second rolling-contacting part 44. The roller 35 pushed by the hook 32 moves toward the elastic member 34 inside the roller shaft accommodating slit 49 corresponding to the length by which the elastic member 34 is pressed. Then, the roller 35 returns to the former position due to a restoring force of the elastic member 34 and contacts to the second roller contacting part 44, which holds a rotation of the hook 32. [0060] If the user slides the door 21 slid out of the main body 10 into the main body 10, the hooking part 31 moves with the door 21 and pushes the second contacting part 41 of the hook 32 to rotate the hook 32. Thus, the hooking part 31 is accommodated in the accommodating groove 39 of the hook 32 and hooked with the hook 32. [0061] Referring to FIG. 5, if the user slides the door 21 slid out of the main body 10 backwardly into the main body 10 when the user draws out the door 21 but the roller 35 still contacts to the first roller contacting part 43, the hooking part 31 pushes an outer surface of the first contacting part 40 of the hook 32 and is accommodated in the accommodating groove 39. At this time, the hook 32 applies force on the roller 35 and presses the elastic member 34 until the roller 35 passes the second rolling guide 47 and contacts to the third roller contacting part 45. At this time, the roller 35 pushed by the hook 32 moves toward the elastic member 34 inside the roller shaft accommodating slit 49 corresponding to the length by which the elastic member 34 is pressed (shown by arrow A in FIG. 5). Then, the roller 35 contacts to the first roller contacting part 43 due to a restoring force of the elastic member 34. [0062] Referring to FIGS. 6 and 7, a door holding device 30′ according to a second embodiment of the present invention includes a hook 32′ including an accommodating part 37 having an accommodating groove 39 to accommodate a hooking part 31, a rotation supporting part 38′ extending from the accommodating part 37 and having a hinge shaft accommodating hole 42 to accommodate a hinge shaft 33, a first protruding part 60 extending from the rotation supporting part 38′ and a second protruding part 62 bent from the first protruding part 60. [0063] The first protruding part 60 has a plate shape and protrudes from the front of the rotation supporting part 38′ and the second protruding part 62 is bent downwardly from the first protruding part 60. [0064] The door holding device 30′ according to the second embodiment of the present invention also includes a supporting bracket 36′. The supporting bracket 36′ includes a first stopper 63 to prevent a rotation of the hook 32′ by contacting to the first protruding part 60 when the hook 32′ is in the first position and a second stopper 63 to prevent a rotation of the hook 32′ by contacting to the second protruding part 60 when the hook 32′ is in the second position. The supporting bracket 36′ also includes a surface having a hinge shaft accommodating slit 65 to accommodate the hinge shaft 33. By way of non-limiting example, the hinge shaft 33 may move in the hinge shaft accommodating slit 65 according to the rotation of the hook 32′. Further, the door holding device 30′ also includes an elastic member 34′, which may be a coil spring. The coil spring may be an extension spring having a first end connected to the supporting bracket 36′ and a second end connected to the hook 32′ to elastically rotate the hook 32′ due to an extension force thereof. [0065] A description of an operation of the door holding device of the Kimchi refrigerator 1 according to the second embodiment of the present invention with a configuration described above follows with concurrent reference to FIGS. 8-10. [0066] As shown in FIG. 8, when the door 21 closes the opening 14 of the main body 10, the hooking part 31 is accommodated in the accommodating part 37 of the hook 32′ and the first stopper 63 contacts to the first protruding part 60 to prevent the rotation of the hook 32′. [0067] Then, as shown in FIG. 9, if a user pulls the door 21 forwardly to draw out the door 21, the hooking part 31 moves forwardly corresponding to a moving direction of the door 21 and the hook 32′ rotates with respect to the hinge shaft 33 to be release from the hooking part 31. At this time, the hook 32′ rotates with respect to the hinge shaft 33 and extends the elastic member 34′ until the second protruding part 62 contacts to the second stopper 64. Thus, the second stopper 64 provided at a lower part of the supporting bracket 36′ prevents the rotation of the hook 32′. If the user slides the door assembly 20 slid out of the main body 10 backwardly into the main body 10, the hooking part 31 moves backwardly along a moving direction of the door 21 and pushes the second contacting part 41 of the hook 32′ to rotate the hook 32′. Thus, the hooking part 31 is accommodated in the accommodating groove 39 and hooked with the hook 32′. [0068] However, as shown in FIG. 10, if the user moves the door 21 backwardly toward the main body 10 when the user draws out the door 21 out of the main body 10 but the first protruding part 60 still contacts to the first stopper 63, the hooking part 31 pushes an outer surface of the first contacting part 40 of the hook 32′ and is accommodated in the accommodating groove 39. At this time, the hinge shaft 33 moves downwardly in the hinge shaft accommodating slit 65, so that the hook 32′ is hooked with the hooking part 31 (refer to the arrow in FIG. 6 c). At this time, a specified force is applied on the hook 32, so that the first protruding part 60 is detached from the first stopper 63. However, the hook 32′ can return to the former position due to a restoring force of the elastic force 34′. [0069] The present invention is embodied as a Kimchi refrigerator having the door holding devices 30 and 30′ in the embodiments described above but not limited thereto. However, it is to be understood that the door holding devices of the present invention may be applied to all of apparatuses having a drawer, especially to furniture. [0070] As described above, the embodiments of the present invention provide a storage in which the main body and the door assembly are more airtight and have a simple structure. [0071] Further, the described embodiments of the present invention provide the storage in which the hook rotates with respect to the hook to be hooked with/released from the hooking part when a user draws the door assembly out of the storage compartment, so that the structure to open/close the door is improved. [0072] Although a few embodiments of the present invention have been shown and described, the present invention is not limited to the described embodiments. Instead, 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 invention, the scope of which is defined by the claims and their equivalents.
