- the protruding member 53 is pulled, by the pusher, in the direction in which the second door 33 is opened, and correspondingly, the rotator 51 is rotated in the second direction L.
- the pillar 4 is operated so as to be unfolded when the pillar boss 41 is inserted into the guide recess 510, and is operated so as to be folded when the pillar boss 41 is removed from the guide recess 510.
- the protrusion 53 is moved rearward to the maximum extent by the second door 33, and the rotator 51 is static in a state in which it is rotated in the first direction R to the maximum extent.
- the guide recess 510 is located at the left side of the rotator 51.
- the pillar boss 41 slides on the first slope 511 (see FIG. 6 ) and passes through the insertion portion 513, thereby being removed from the guide recess 510 (see FIG. 7 ).
- the pillar boss 41 Since the first slope 511 is convex rearward, the pillar boss 41 is rotated in the first direction R, and larger force than the elastic force of the pillar spring (not illustrated) provided inside the pillar 4 is applied to the pillar boss 41, thus causing the pillar 4 to be folded.

- A pillar provided in a refrigerator according to one embodiment of the present invention will be described below with reference to
FIG. 1 . - The refrigerator of the present invention may include a
cabinet 1 defining an external appearance of the refrigerator, astorage compartment 2 defined inside thecabinet 1, afirst door 31 and a second door 32 pivotably provided respectively at the left and right sides of thecabinet 1 in order to open or close thestorage compartment 2, apillar 4 provided at thefirst door 31, apillar boss 41 formed on the top of thepillar 4, and arotator 51 having aguide recess 510 configured to guide thepillar boss 41. - As such, the present invention provides the refrigerator in which the
pillar 4 is unfolded to seal a gap between thedoors doors pillar 4 is folded in a state in which at least one of thedoors - Hereinafter, considering a configuration of the refrigerator, the
storage compartment 2 refers to a space in which storage items may be stored. The storage compartment may be divided into a freezing compartment in which storage items are stored at a temperature below zero degrees, and a refrigerating compartment in which storage items are stored at a temperature higher than zero degrees. - The
storage compartment 2 may include ashelf 21 on which the storage items may be placed, and avegetable box 23 which is configured to receive storage items therein and to be pulled out of thestorage compartment 2. - The
doors storage compartment 2. Thedoors first door 31, which is hinged to the left side of thecabinet 1 and is pivotable, and thesecond door 33 which is hinged to the right side of thecabinet 1 and is pivotable. - Each of the
first door 31 and thesecond door 33 may be provided at a rear surface thereof with adoor basket 311 so as to receive storage items therein. - In addition, a
gasket 331 is provided at the periphery of the rear surface of each of thefirst door 31 and thesecond door 33, and prevents cold air from being discharged between thedoors cabinet 1. - Although the
pillar 4 is provided at thefirst door 31 in one embodiment of the present invention, in another embodiment, thepillar 4 may be provided at the second door 3, and other components related thereto may correspondingly be provided and operated in the opposite configuration. - Referring to
FIG. 2 , thepillar 4 takes the form of an elongated bar. That is, thepillar 4 is long in the vertical direction and wide in the horizontal direction. Thepillar 4 may incorporate a pillar spring (not illustrated) therein, and the elastic force of the pillar spring (not illustrated) becomes minimum force that must be supplied to thepillar 4 so as to allow thepillar 4 to be folded or unfolded. - Alternatively, there is present a first angle, which is an angular range to cause the
pillar 4 to be changed between a folded state and an unfolded state. Thus, when external force is applied to exceed the first angle when thepillar 4 is in the unfolded state, thepillar 4 is folded. Contrary, when external force is applied to exceed the first angle when thepillar 4 is in the folded state, thepillar 4 is unfolded. - Although the
pillar boss 41 may have a circular pole shape, thepillar boss 41 may have an oval pole shape in order to increase the radius of curvature. - The
pillar boss 41 protrudes from the top of thepillar 4. Thepillar 4 incorporates a pillar boss spring (not illustrated) therein to support thepillar boss 41 such that thepillar boss 41 is movable up and down. - Accordingly, it is possible to prevent the
pillar boss 41 from being damaged while being guided to theguide recess 510. - Referring to
FIGs. 3 and4 , theguide recess 510 has a prescribed space therein in order to guide thepillar boss 41. - More specifically, the
guide recess 510 includes aninsertion portion 513 which is open for the insertion of thepillar boss 41, a first slope 511 (which may also be referred to as a first curved portion) which is connected to theinsertion portion 513 and is located close to thedoors first slope 51 being convex rearward, and a second slope 512 (which may also be referred to as a second curved portion) which is connected to theinsertion portion 513 and is located far from thedoors second slope 512 being concave forward. - Alternatively, the
guide recess 510 may include theinsertion portion 513 which is open to allow the insertion and removal of thepillar boss 41, thefirst slope 511 which is configured to guide thepillar boss 41 when thepillar boss 41 is removed from theinsertion portion 513, and thesecond slope 512 which is configured to guide thepillar boss 41 when thepillar boss 41 is inserted into theinsertion portion 513. - In this case, a prescribed space is defined between the
first slope 511 and thesecond slope 512 so as to guide thepillar boss 41. Thefirst slope 511 is convex and thesecond slope 512 is concave. - Here, the
insertion portion 513 is wider than thepillar boss 41. This prevents thepillar boss 41 from being damaged by colliding with the periphery of theinsertion portion 513 when thepillar boss 41 is inserted into theinsertion portion 513 due to the assembly tolerance of thedoors pillar 4. - The
rotator 51 includes theguide recess 510, and is provided belowhousings 55 and 56 (which will be described below), which are installed at the ceiling of thestorage compartment 2, so as to be rotatable about the rotation axis C. Since thehousings rotator 51 may be rotatably provided at the ceiling of thestorage compartment 2. In addition, theguide recess 510 may be formed in an inner case of thestorage compartment 2. - In addition, the
rotator 51 may take the form of a fan-shaped plate. Here, a straight portion of the fan-shapedrotator 51 is configured so as not to protrude forward from a top surface of thestorage compartment 2 even if therotator 51 is rotated, thus having no risk of interference with thedoors - The
storage compartment 2 may have a concavely stepped fixing portion (not illustrated) at the ceiling thereof, and therotator 51 and thehousings rotator 51 and thehousings storage compartment 2. - Here, as definitions related to rotation directions, which will be described in the specification, when viewing the
rotator 51 from the top side, the counterclockwise direction or the right-handed screw direction is referred to as a first direction R, and the clockwise direction or the left-handed screw direction is referred to as a second direction L. The first direction R and the second direction L are applied not only to the rotation of therotator 51, but also to the rotation of thepillar 4. - Meanwhile, the refrigerator according to one embodiment of the present invention may further include a protruding
member 53 connected to therotator 51 and anelastic member 571 connected to therotator 51. - The protruding
member 53 is configured to protrude downward from therotator 51. There is the rotation axis C between theguide recess 510 and the protrudingmember 53. That is, in one embodiment of the present invention, when viewing therotator 51 from the top side, theguide recess 510 is located at the left side of therotator 51 and the protrudingmember 53 is located at the right side of therotator 51. - In addition, the protruding
member 53 may be spaced apart from the rotation axis C to the maximum extent, so as to allow more torque to be applied when force is supplied in order to rotate therotator 51. - Accordingly, the protruding
member 53 comes into contact with thesecond door 33 when thesecond door 33 is closed, and is pushed rearward by the closing force of thesecond door 33, thereby rotating therotator 51 in the first direction R. - In this case, the protruding
member 53 may come into contact with a pusher (not illustrated) which protrudes from the rear surface of thesecond door 33, or may come into contact with thedoor basket 311 provided at the rear surface of thesecond door 33. - The protruding
member 53 may be rotatably provided in a protruding memberfitting hole 515 formed in therotator 51. In another embodiment, the protrudingmember 53 may be integrally formed at the underside of therotator 51. - Meanwhile, the
elastic member 571 provides elastic force required to allow therotator 51 to be rotated in the second direction L. - The
elastic member 571 may include a spring. - The rotation axis C may be present between the
guide recess 510 and theelastic member 571. That is, theelastic member 571 is located at the right side of therotator 51. - In this case, the
elastic member 571 is compressed when therotator 51 is rotated in the first direction R, and returns to an original state thereof when therotator 51 is rotated in the second direction L. That is, therotator 51 is rotated in the second direction L using the compressive elastic force of theelastic member 571. - Meanwhile, in order to enhance the operation ability of the
elastic member 571, the refrigerator of the present invention may further include thehousings storage compartment 2, and guides 573 and 567 for theelastic member 571 provided inside thehousings - The
housings upper housing 56 and thelower housing 56. Therotator 51 is provided on a lower surface of thelower housing 55 so as to be rotatable about the rotation axis C. - The
guides housings first guide 573 into which theelastic member 571 is fitted, and thesecond guide 567 formed in thelower housing 55 in order to guide thefirst guide 573. - The
second guide 567 has a through-hole 567a into which one end of thefirst guide 573 is fitted so as to be guided. - The
first guide 573 has an expandedportion 573a formed at the other end thereof, the expandedportion 573a having a greater diameter than thefirst guide 573 so as to prevent theelastic member 571 from being removed from thefirst guide 573. - As such, the
elastic member 571 is fitted into thefirst guide 573, and in turn, thefirst guide 573 is fitted into the through-hole 567a so as to be guided in the front-and-rear direction. With this guidance, theelastic member 571 is compressed between the expandedportion 573a and the through-hole 567a. - Meanwhile, in order to enhance the elastic force of the
elastic member 571, two elastic members may be provided. Thus, in order to guide the respectiveelastic members 571, twofirst guides 573, two expandedportions 573a, twosecond guides 567, and two through-holes 567a may be provided. - In this case, the two expanded
portions 573a may be integrally formed with each other, which allow the twoelastic members 571 to be moved in the same manner. - Meanwhile, in a case where the
elastic members 571 and theguides housings linkage member 58 configured to connect the expandedportions 573a and therotator 51 to each other, and athird guide 555 formed in thelower housing 55 to enable the movement of thelinkage member 58. - As such, the elastic force of the
elastic members 571 may be transmitted to therotator 51 so as to rotate therotator 51. - The
third guide 555 takes the form of an elongated rectangular hole having a prescribed length in the front-and-rear direction, thethird guide 555 being perforated in the lower surface of thelower housing 55 and serving to allow thelinkage member 58 to be linearly moved in the front-and-rear direction. - In addition, in one embodiment of the present invention, as the protruding
member 53 and thelinkage member 58 are directly connected to each other using the same shaft, forces to rotate therotator 51 in different directions are present on the same shaft. - As such, when the
rotator 51 is rotated, unsmooth rotation such as, for example, rattling of therotator 51, which is caused by opposite forces applied at different distances from the rotation axis C, may hardly occur. - In this case, the protruding member
fitting hole 515 must be perforated in therotator 51 so as to have a prescribed area, in order to ensure that the rotating shaft of the protrudingmember 53 connected to therotator 51 is movable inside the protruding memberfitting hole 515. This is because thelinkage member 58 is linearly moved in the front-and-rear direction by thethird guide 555 and the protrudingmember 53 connected to therotator 51 is rotated, which causes the protrudingmember 53 and thelinkage member 58 to conflict with each other when connected using the same shaft. - Accordingly, as the rotating shaft of the protruding
member 53 is movable in the protruding memberfitting hole 515, the protrudingmember 53 is also linearly movable in the front-and-rear direction. - In addition, the
lower housing 55 may have afourth guide 553 perforated therein in order to prevent therotator 51 from falling down from thehousings rotator 51, and therotator 51 may further include a support piece 513' which is connected to therotator 51 through thefourth guide 553 so as to be guided by thefourth guide 553. - In the refrigerator according to another embodiment of the present invention, the protruding
member 53 may include aflat contact portion 531 so as to come into surface contact with thesecond door 33 or the pusher (not illustrated). - That is, the protruding
member 53 may have a semicircular pole shape, and thecontact portion 531 may be formed as a flat surface formed at the diameter of a semicircle. - The
contact portion 531 may incorporate a first magnet therein, and a second magnet may be incorporated inside the pusher (not illustrated). The first magnet and the second magnet have different polarities so as to be attracted to each other. - As such, when the
second door 33 is opened, the protrudingmember 53 is pulled, by the pusher, in the direction in which thesecond door 33 is opened, and correspondingly, therotator 51 is rotated in the second direction L. - Through provision of the
guide recess 510, thepillar 4 is operated so as to be unfolded when thepillar boss 41 is inserted into theguide recess 510, and is operated so as to be folded when thepillar boss 41 is removed from theguide recess 510. - Hereinafter, the folding and unfolding operations of the
pillar 4 upon the opening and closing of thefirst door 31 and thesecond door 33 will be described with reference toFIGs. 5 ,6 and7 . - First, a folding configuration of the
pillar 4 when thefirst door 31 is opened and an unfolding configuration of thepillar 4 when thefirst door 31 is closed will be described. - Referring to
FIG. 5 , in a state in which thesecond door 33 is closed, theprotrusion 53 is moved rearward to the maximum extent by thesecond door 33, and therotator 51 is static in a state in which it is rotated in the first direction R to the maximum extent. In addition, as described above, theguide recess 510 is located at the left side of therotator 51. - Here, when the
first door 31 is opened, thepillar boss 41 slides on the first slope 511 (seeFIG. 6 ) and passes through theinsertion portion 513, thereby being removed from the guide recess 510 (seeFIG. 7 ). - Since the
first slope 511 is convex rearward, thepillar boss 41 is rotated in the first direction R, and larger force than the elastic force of the pillar spring (not illustrated) provided inside thepillar 4 is applied to thepillar boss 41, thus causing thepillar 4 to be folded. That is, folding torque applied to thepillar boss 41 by thefirst slope 511 must be larger than the elastic force of the pillar spring described above. - Alternatively, once the
pillar boss 41 has been removed from theinsertion portion 513, thepillar 4 is rotated beyond the first angle, thereby being folded. - Accordingly, as the
pillar 4 is folded as exemplarily illustrated inFIG. 6 , when thefirst door 31 is opened, thepillar 4 hardly collides with thesecond door 33 or thedoor basket 311 of thesecond door 33, and thepillar 4 hardly protrudes from the side surface of thesecond door 31, which may improve the aesthetic appearance of the refrigerator. - Although not illustrated in the drawings, contrary, when the
first door 31 is closed, thepillar boss 41 is introduced into theinsertion portion 513 and comes into contact with thesecond slope 512 so as to slide on thesecond slope 512. Thereby, thepillar boss 41 is inserted inside theguide recess 510. - Since the
second slope 512 is concave forward, thepillar boss 41 is rotated in the second direction L, and larger force than the elastic force of the pillar spring (not illustrated) provided inside thepillar 4 is applied to thepillar boss 41, thus causing thepillar 4 to be unfolded. - That is, the
pillar boss 41 receives unfolding torque required to allow thepillar 4 to be unfolded by sliding and rotating on thesecond slope 512, and the unfolding torque must be larger than the elastic force of the pillar spring described above. - Alternatively, as the
pillar 4 is rotated beyond the first angle while thepillar boss 41 is being guided by thesecond slope 512, thepillar 4 is unfolded. - Accordingly, the
pillar 4 is unfolded and seals a gap between thefirst door 31 and thesecond door 33 so as to prevent leakage of cold air. - Hereinafter, a folding configuration of the
pillar 4 when thesecond door 33 is opened will be described with reference toFIGs. 8 ,9 and10 . -
FIG. 8 illustrates a state in which both thefirst door 31 and thesecond door 33 are closed. In such a state, the protrudingmember 53 is pushed rearward by thesecond door 33, and therotator 51 is rotated in the first direction R to the maximum extent. - This is because the closing force of the
second door 33 is larger than the elastic force of theelastic member 571. The closing force of thesecond door 33 may include, for example, the weight of thedoor 33, the weight of items stored in thedoor basket 311, and magnetic force of the magnet in the closed state of thedoor 33. - In this case, the
pillar 4 is in the unfolded state, and prevents leakage of cold air between thefirst door 31 and thesecond door 33. - As exemplarily illustrated in
FIG. 9 , when thesecond door 33 begins to be opened, the closing force of thesecond door 33 applied to therotator 51 is removed, and therefore therotator 51 is rotated in the second direction L by the elastic force of theelastic member 571. - Thereby, the
guide recess 510 formed in therotator 51 is also rotated in the second direction L. - Force is applied to the
pillar boss 41 located in theguide recess 510 by thefirst slope 511 in the direction in which thepillar 4 is rotated (i.e. the first direction R). Since this force is larger than the elastic force of the pillar spring (not illustrated) provided inside thepillar 4, thepillar 4 is rotated toward thefirst door 31. - That is, the elastic force of the
elastic member 571 must be larger than the elastic force of the pillar spring of thepillar 4 in order to ensure that thepillar 4 may be folded. Thus, as exemplarily illustrated inFIG. 10 , thepillar 4 is folded when thesecond door 33 is completely opened. - Alternatively, the
pillar 4 is rotated beyond the first angle to thereby be folded when thepillar boss 41 is removed from theinsertion portion 513. - Since the
pillar 4 is in the folded state, thepillar 4 does not cover an opening of thestorage compartment 2 that is opened or closed by thesecond door 33, which allows thevegetable box 23 provided inside thestorage compartment 2 to be configured to have a great volume, and may prevent the user from being blocked by thepillar 4 when introducing or retrieving storage items. - Hereinafter, an unfolding configuration of the
pillar 4 when thesecond door 33 is closed will be described with reference toFIGs. 11 ,12 and13 . -
FIG. 11 illustrates a state in which thesecond door 33 is opened. In such a state, therotator 51 is rotated in the second direction L to the maximum extent by the elastic member 571 (seeFIG. 10 ), and thepillar 4 is folded. In addition, the protrudingmember 53 is moved toward thesecond door 33. - As exemplarily illustrated in
FIG. 12 , when thesecond door 33 is being closed, thesecond door 33 comes into contact with the protrudingmember 53. The closing force of thesecond door 33 is transmitted through the protrudingmember 53 to therotator 51 so as to rotate therotator 51 in the first direction R. As such, theguide recess 510 formed in therotator 51 is also rotated in the first direction R. - In this case, the
pillar boss 41 is inserted into theguide recess 510 through theinsertion portion 513. Thesecond slope 512 applies force to thepillar boss 41 in the direction in which thepillar 4 is rotated (i.e. the second direction L), and comes into contact with thepillar boss 41 so as to guide thepillar boss 41. - Accordingly, as exemplarily illustrated in
FIG. 13 , thepillar 4 is unfolded when thesecond door 33 is completely closed, thereby preventing leakage of cold air between thefirst door 31 and thesecond door 33. - Alternatively, the
pillar boss 41 is guided by thesecond slope 512 and is unfolded when thepillar 4 is rotated beyond the first angle. - As described above, as the
rotator 51 is rotated when thesecond door 33 is opened or closed, theguide recess 510 is also rotated, and thepillar boss 41 is guided by therotating guide recess 510. With this operation, the refrigerator of the present invention achieves enhanced operation ability compared to a pillar and a pillar guide of the related art. - This is because the
guide recess 510 pushes thepillar boss 41 in the direction in which thepillar 4 is rotated, in order to rotate thepillar 4. In other words, since theguide recess 510 pushes thepillar boss 41 in the tangential direction of the radius of rotation of thepillar 4, rather than pushing thepillar boss 41 in the rotation axis direction of thepillar 4, torque applied to thepillar 4 is increased. - Meanwhile,
FIGs. 14 to 22 illustrate a refrigerator according to another embodiment of the present invention.FIGs. 14 to 22 sequentially correspond toFIGs. 5 to 13 . A description except for a difference as follows overlaps the above description with reference toFIGs. 5 to 13 , and thus will be omitted below. - As exemplarily illustrated in
FIGs. 14 to 22 , thepillar 4 is pivotably provided at thefirst door 31 using acoupler 43 and is secured to the side surface of thedoor basket 311 provided at thefirst door 31. - As is apparent from the above description, with a refrigerator according to the exemplary embodiments of the present invention, when a user opens a door and pulls out a vegetable pulled out from a storage compartment, there occurs no interference between a pillar and the vegetable box, which may result in increased convenience of use.
- In addition, according to the present invention, there occurs no interference between a pillar and a door basket when a door is opened, which may increase the practical storage capacity of the door basket.
- In addition, according to the present invention, as a pillar is folded when a door is opened, which may result in increased usability and increased storage capacity.
- Although the exemplary embodiments have been illustrated and described as above, of course, it will be apparent to those skilled in the art that the embodiments are provided to assist understanding of the present invention and the present invention is not limited to the above described particular embodiments, and various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention, and the modifications and variations should not be understood individually from the viewpoint or scope of the present invention.
