- the shelf hanger 80 may include a guide groove 84 extending in the vertical direction.
- the guide groove 84 may be formed by coupling the first frame 81 and the second frame 82.
- a first roller 92 of the moving unit 90 may not be deviated from the shelf hanger 80 by the guide groove 84.
- the guide groove 84 may be provided to have a transverse width smaller than that of the first roller 92, which will be described below, and larger than a diameter of a first fastening member 93.
- the moving unit 90 may include a body part 91, the first roller 92, a second roller 94, an engagement lever 96, a second elastic member 99, and a switching bar 98.
- the first roller 92 and the second roller 94 may assist movement of the moving unit 90 in the vertical direction of the shelf hanger 80.
- the first roller 92 and the second roller 94 come into contact with the shelf hanger 80 and are rotated so that a frictional force can be reduced and the moving unit 90 can be stably moved.
- a plurality of first rollers 92 and second rollers 94 may be provided. According to the present embodiment, a pair of first rollers 92 and a pair of second rollers 94 may be provided.
- the first roller 92 may be coupled to the body part 91 by fastening the first fastening member 93 to the body part 91.
- the second roller 94 may be coupled to the body part 91 by fastening a second fastening member 95 to the body part 91.
- the first fastening member 93 and the second fastening member 95 couple the first roller 92 and the second roller 94 to the body part 91 and also function as rotational axes of the first roller 92 and the second roller 94.
- the engagement lever 96 may be coupled to the body part 91 via a third fastening member 97. Like the first roller 92 and the second roller 94, the engagement lever 96 may be rotated with respect to the third fastening member 97, which acts as a rotation axis thereof.
- the second elastic member 99 may be provided between the engagement lever 96 and the body part 91 to elastically bias the engagement lever 96 in one direction.
- a torsion spring may be provided as the second elastic member 99.
- the present disclosure is not limited thereto.
- the moving unit 90 may further include the switching bar 98.
- the switching bar 98 may be provided between moving units provided on left and right sides of the shelf 100.
- the switching bar 98 may be provided to be rotated with the engagement lever 96. Due to the above configuration, the user may rotate the switching bar 98 to rotate the engagement lever 96 without directly rotating the engagement lever 96. That is, the switching bar 98 may be provided to rotate the engagement lever 96.
- the shelf 100 may be coupled to the moving unit 90, and food and the like may be put on the shelf 100. At this time, weight may not be uniformly distributed on each of the moving units provided on the left and left sides of the shelf 100.
- the switching bar 98 may be provided between the moving units. That is, the switching bar 98 may rotate the engagement lever 96 and also reinforce a structure of the moving unit 90.
- FIG. 5 is a view illustrating a state in which the moving unit is coupled to the shelf hanger in the refrigerator of FIG. 1 .
- FIGS. 6 and 7 are views for describing an operation of moving the moving unit of FIG. 5 upward
- FIGS. 8 and 9 are views for describing an operation of moving the moving unit of FIG. 7 downward.
- a vertical height adjustment operation of the moving unit 90 will be described in detail with reference to FIGS. 5 to 9 below.
- the moving unit 90 may be fixed to the shelf hanger 80 by engaging the engagement lever 96 with the engagement projection 83 of the shelf hanger 80. Further, the moving unit 90 may be unfixed by disengaging the engagement lever 96 from the engagement projection 83. The engagement and disengagement of the engagement lever 96 and the engagement projection 83 may be adjusted by rotating the engagement lever 96. The second elastic member 99 may elastically bias the engagement lever 96 in one direction, and the engagement lever 96 may be rotated in the other direction to disengage the engagement lever 96 from the engagement projection 83.
- the engagement lever 96 When the moving unit 90 is moved upward, the engagement lever 96 is gradually rotated in the other direction by a first inclined portion 83a of the engagement projection 83. That is, even when the user simply lifts the shelf 100 without rotating the switching bar 98, the engagement lever 96 and the switching bar 98 are rotated in the other direction by the first inclined portion 83a.
- the engagement lever 96 When the moving unit 90 is continuously moved upward, the engagement lever 96 is gradually rotated in the other direction at the first inclined portion 83a and is then rotated in the one direction again at a second inclined portion 83b provided at one end of the first inclined portion 83a by an elastic force of the second elastic member 99. As the engagement lever 96 is rotated in the one direction at the second inclined portion 83b, the engagement lever 96 is engaged with the engagement projection 83 and the moving unit 90 is fixed to the shelf hanger 80.
- the engagement lever 96 When the moving unit 90 is moved downward, unlike the case in which the moving unit is moved upward, the engagement lever 96 is not rotated in the other direction even when the user exerts a downward force on the moving unit 90.
- the reason for this is that since a downward force is already being exerted on the moving unit 90 by the shelf 100, food placed on the shelf 100, and a weight of the moving unit 90, the moving unit 90 may not support the shelf 100 when the engagement lever 96 is rotated in the other direction.
- the user may rotate the switching bar 98 forward to artificially rotate the engagement lever 96 in the other direction. That is, the engagement lever 96 is disengaged from the engagement projection 83 to unfix the moving unit 90 fixed to the shelf hanger from the shelf hanger 80.
- the moving unit 90 When the moving unit 90 is unfixed, the user may move a location of the shelf 100 downward to adjust the height thereof to be lower without needing to continuously rotate the switching bar 98.
- the shelf of the present disclosure has an advantage in that the height of the shelf may be adjusted without detaching the shelf from the shelf hanger so that the height of the shelf may be adjusted without taking food placed on the shelf out of the refrigerator or moving the food in the refrigerator.
- the user since a separate switching operation, which is inconvenient due to food placed on the shelf, is not required when the shelf is moved upward, the user may conveniently adjust the height of the shelf. That is, according to the spirit of the present disclosure, it is possible to provide a shelf which improves user convenience.
- FIG. 10 is an exploded view of the shelf of the refrigerator according to one embodiment of the present disclosure

- the first latch unit 141 and the second latch unit 142 are fixed, even though the first elastic member 126 applies the elastic force to withdraw the second shelf 120 from the first shelf 110, the second shelf 120 is not withdrawn.
- the first latch unit 141 and the second latch unit 142 are unfixed, the second shelf 120 may be withdrawn from the first shelf 110 by the elastic force of the first elastic member 126.
- the damper 143 may adjust the withdrawal speed of the second shelf 120 to prevent the food placed on the second shelf 120 from falling off the second shelf 120 due to the second shelf 120 being rapidly withdrawn.
- first elastic member 126 may be supported by one side of the second shelf 120, and the other end thereof may be supported by a support wall 113 provided at the first shelf 110.
- first elastic member 126 may provide the elastic force to allow the second shelf 120 to be moved away from the first shelf 110. That is, the first elastic member 126 may elastically bias the second shelf 120 in one direction in which the second shelf 120 is withdrawn from the first shelf 110.

- The shelf may be provided such that a height thereof may be adjusted according to convenience of a user, and may be provided to be slidable in a front-rear direction.
- In an existing refrigerator, when a user desires to adjust a height of a shelf, the shelf should be completely separated from a hanger provided on a rear wall of a storage compartment. During the process of separating the shelf from the hanger, food put on the shelf may fall into the storage compartment. Therefore, a user must take all the food put on the shelf out of the refrigerator before adjusting the height of the shelf, and put the food on the shelf again after the height of the shelf is adjusted. In addition, there is an inconvenience in that an operation of mounting the shelf, such as an operation for leveling the shelf and the like, should be performed whenever the height of the shelf is adjusted.
- Further, even in the case of a shelf which is slidable in the front-rear direction, since the shelf is not completely withdrawn in the frontward direction, it is inconvenient for a user to take out food and the like put on the shelf.
- Therefore, it is an aspect of the present disclosure to provide a refrigerator which allows a height of a shelf to be adjusted without detaching the shelf from a hanger.

FIG. 4 is an exploded view illustrating the shelf hanger and the moving unit in the refrigerator ofFIG. 1 . - Hereinafter, configurations of the
shelf hanger 80 and the movingunit 90 will be described in detail with reference toFIG. 4 . - The
shelf hanger 80 may include afirst frame 81 and asecond frame 82. Each of thefirst frame 81 and thesecond frame 82 may include a fastening groove, and thefirst frame 81 and thesecond frame 82 may be coupled by fastening a fastening member (not shown) to the fastening grooves. - The
shelf hanger 80 may include a plurality ofengagement projections 83 provided in the vertical direction. The movingunit 90 may be supported by any oneengagement projection 83 of the plurality of engagement projections. The movingunit 90 may be selectively engaged with any one of the plurality of engagement projections to adjust the height of the shelf in the vertical direction. - The
shelf hanger 80 may include aguide groove 84 extending in the vertical direction. Theguide groove 84 may be formed by coupling thefirst frame 81 and thesecond frame 82. Afirst roller 92 of the movingunit 90 may not be deviated from theshelf hanger 80 by theguide groove 84. To this end, theguide groove 84 may be provided to have a transverse width smaller than that of thefirst roller 92, which will be described below, and larger than a diameter of afirst fastening member 93. - The moving
unit 90 may include abody part 91, thefirst roller 92, asecond roller 94, anengagement lever 96, a secondelastic member 99, and a switchingbar 98. - The
first roller 92 and thesecond roller 94 may assist movement of the movingunit 90 in the vertical direction of theshelf hanger 80. When the movingunit 90 is moved in the vertical direction, thefirst roller 92 and thesecond roller 94 come into contact with theshelf hanger 80 and are rotated so that a frictional force can be reduced and the movingunit 90 can be stably moved. - A plurality of
first rollers 92 andsecond rollers 94 may be provided. According to the present embodiment, a pair offirst rollers 92 and a pair ofsecond rollers 94 may be provided. - The
first roller 92 may be coupled to thebody part 91 by fastening thefirst fastening member 93 to thebody part 91. Similarly, thesecond roller 94 may be coupled to thebody part 91 by fastening asecond fastening member 95 to thebody part 91. In this case, thefirst fastening member 93 and thesecond fastening member 95 couple thefirst roller 92 and thesecond roller 94 to thebody part 91 and also function as rotational axes of thefirst roller 92 and thesecond roller 94. - The
engagement lever 96 may be coupled to thebody part 91 via athird fastening member 97. Like thefirst roller 92 and thesecond roller 94, theengagement lever 96 may be rotated with respect to thethird fastening member 97, which acts as a rotation axis thereof. The secondelastic member 99 may be provided between theengagement lever 96 and thebody part 91 to elastically bias theengagement lever 96 in one direction. In the embodiment, a torsion spring may be provided as the secondelastic member 99. However, the present disclosure is not limited thereto. - The moving
unit 90 may further include the switchingbar 98. The switchingbar 98 may be provided between moving units provided on left and right sides of theshelf 100. The switchingbar 98 may be provided to be rotated with theengagement lever 96. Due to the above configuration, the user may rotate the switchingbar 98 to rotate theengagement lever 96 without directly rotating theengagement lever 96. That is, the switchingbar 98 may be provided to rotate theengagement lever 96. - The
shelf 100 may be coupled to the movingunit 90, and food and the like may be put on theshelf 100. At this time, weight may not be uniformly distributed on each of the moving units provided on the left and left sides of theshelf 100. To compensate for this, the switchingbar 98 may be provided between the moving units. That is, the switchingbar 98 may rotate theengagement lever 96 and also reinforce a structure of the movingunit 90. -
FIG. 5 is a view illustrating a state in which the moving unit is coupled to the shelf hanger in the refrigerator ofFIG. 1 .FIGS. 6 and7 are views for describing an operation of moving the moving unit ofFIG. 5 upward, andFIGS. 8 and9 are views for describing an operation of moving the moving unit ofFIG. 7 downward. - A vertical height adjustment operation of the moving
unit 90 will be described in detail with reference toFIGS. 5 to 9 below. - The moving
unit 90 may be fixed to theshelf hanger 80 by engaging theengagement lever 96 with theengagement projection 83 of theshelf hanger 80. Further, the movingunit 90 may be unfixed by disengaging theengagement lever 96 from theengagement projection 83. The engagement and disengagement of theengagement lever 96 and theengagement projection 83 may be adjusted by rotating theengagement lever 96. The secondelastic member 99 may elastically bias theengagement lever 96 in one direction, and theengagement lever 96 may be rotated in the other direction to disengage theengagement lever 96 from theengagement projection 83. - According to the spirit of the present disclosure, when the moving
unit 90 is moved upward, a separate switching operation of the user is not required. Conversely, when the movingunit 90 is moved downward, it is necessary for the user to rotate the switchingbar 98. - When the moving
unit 90 is moved upward, theengagement lever 96 is gradually rotated in the other direction by a firstinclined portion 83a of theengagement projection 83. That is, even when the user simply lifts theshelf 100 without rotating the switchingbar 98, theengagement lever 96 and the switchingbar 98 are rotated in the other direction by the firstinclined portion 83a. - When the moving
unit 90 is continuously moved upward, theengagement lever 96 is gradually rotated in the other direction at the firstinclined portion 83a and is then rotated in the one direction again at a second inclined portion 83b provided at one end of the firstinclined portion 83a by an elastic force of the secondelastic member 99. As theengagement lever 96 is rotated in the one direction at the second inclined portion 83b, theengagement lever 96 is engaged with theengagement projection 83 and the movingunit 90 is fixed to theshelf hanger 80. - When the moving
unit 90 is moved downward, unlike the case in which the moving unit is moved upward, theengagement lever 96 is not rotated in the other direction even when the user exerts a downward force on the movingunit 90. The reason for this is that since a downward force is already being exerted on the movingunit 90 by theshelf 100, food placed on theshelf 100, and a weight of the movingunit 90, the movingunit 90 may not support theshelf 100 when theengagement lever 96 is rotated in the other direction. - Accordingly, the user may rotate the switching
bar 98 forward to artificially rotate theengagement lever 96 in the other direction. That is, theengagement lever 96 is disengaged from theengagement projection 83 to unfix the movingunit 90 fixed to the shelf hanger from theshelf hanger 80. When the movingunit 90 is unfixed, the user may move a location of theshelf 100 downward to adjust the height thereof to be lower without needing to continuously rotate the switchingbar 98. - Unlike a conventional shelf, the shelf of the present disclosure has an advantage in that the height of the shelf may be adjusted without detaching the shelf from the shelf hanger so that the height of the shelf may be adjusted without taking food placed on the shelf out of the refrigerator or moving the food in the refrigerator. In addition, since a separate switching operation, which is inconvenient due to food placed on the shelf, is not required when the shelf is moved upward, the user may conveniently adjust the height of the shelf. That is, according to the spirit of the present disclosure, it is possible to provide a shelf which improves user convenience.
