Description

Rotating shelf and refrigerator including the same

[0001] The present disclosure relates to a rotating shelf and a refrigerator including the same, and more specifically, to a rotating shelf and a refrigerator that allows items stored at the rear of the shelf to be easily retrieved and the storage space at the rear of the shelf to be utilized.

[0002] Generally, a refrigerator is a home appliance designed to store food at low temperatures within an internal storage space enclosed by a door. To achieve this, the refrigerator is configured to maintain stored food in optimal conditions by cooling the interior of the storage space using cold air generated through heat exchange with a refrigerant circulating in a freezing cycle.

[0003] To efficiently utilize the entire storage space of a refrigerator, shelves are used to partition the space vertically. While these shelves expand vertical usability, items placed at the rear of the shelf are difficult for users to retrieve. Consequently, users tend to store items only at the front of the shelf, leading to a problem where usability in the front-to-back direction is reduced.

[0004] In the case of Patent Document 1, a shelf of a general refrigerator is disclosed, but in this case, when a storage item is stored at the rear end of the shelf, there is a problem that it is difficult to retrieve the storage item placed at the rear end of the shelf.

[0005] In the case of Patent Document 2, at least one carrier plate (3) having a bearing area (5) and a shelf (2) capable of rotating and translating on the bearing area (5) of the carrier plate (3) are featured, but there is a problem in that the rotation and translation movements are not smooth due to the complex structure of the bearing area and the shelf can be easily separated from the carrier plate.

[0009] The object of the present disclosure is to provide a rotating shelf that allows a user to easily retrieve a stored item placed at the rear end of the shelf, and a refrigerator including the same.

[0010] Another objective of the present disclosure is to provide a rotating shelf and a refrigerator that efficiently utilize the storage space at the rear end of the shelf.

[0011] Another objective of the present disclosure is to provide a rotating shelf and a refrigerator including the same, wherein the length of the rotating plate is maximized within a range that does not interfere with the storage space, so that the rotating plate is rotated after being pulled out of the shelf base.

[0012] Another objective of the present disclosure is to provide a rotating shelf and a refrigerator including the same, which allows the rotating plate to be smoothly withdrawn and rotated from the shelf base and has improved structural rigidity.

[0013] The problems of the present disclosure are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0014] A rotary lathe according to one aspect of the present disclosure for achieving the above-described purpose is characterized in that a rotary plate installed on a lathe base rotates 180 degrees after being moved forward by a slide lathe.

[0015] Specifically, a rotary lathe according to one aspect of the present disclosure comprises a lathe base, a slide lathe installed on the lathe base to translate about the lathe base, and a rotary plate installed on the slide lathe to rotate about a rotation axis about the slide lathe, wherein the slide lathe translates between a first position and a second position in which the area overlapping with the lathe base in the direction of the rotation axis is smaller than the first position, and the rotary plate rotates at the second position.

[0016] The length of the first direction, which is the translational motion direction of the slide shelf of the above-mentioned rotating plate, may be shorter than the length of the second direction that intersects the first direction of the above-mentioned rotating plate.

[0017] The above-described rotating plate includes a long edge facing in the first direction and a short edge facing in the second direction, wherein the long edge is in the shape of a straight line and the short edge may be in the shape of an arc having a center within the rotating plate.

[0018] Additionally, the present disclosure may further include a slider coupled to the slide shelf and sliding on the shelf base.

[0019] The shelf base may include a base plate and sliding guides disposed at both ends of one direction of the base plate to guide the slider.

[0020] The above sliding guide may include a top guide positioned to face a part of the base plate and a horizontal guide that separates the top guide from the base plate.

[0021] The above slider can slide in the space between the top guide and the base plate.

[0022] The above slider may include a vertical slider that contacts the top guide and the base plate to restrict vertical movement, and a horizontal slider that separates the vertical slider from the horizontal guide.

[0023] The above slider may further include a fastening portion to which a fastening member is coupled for fastening the vertical slider to the sliding shelf.

[0024] The length of the above horizontal guide may be longer than the length of the above top guide.

[0025] The top guide may be positioned adjacent to the front end of the horizontal guide in the horizontal guide.

[0026] The shelf base may further include a base cover disposed at one end of the other direction of the base plate and covering a part of the rotating plate at the first position.

[0027] The above slide shelf may include a space board to which the rotation axis of the rotation plate is coupled and which provides a space on the upper side for the rotation plate to rotate, slide side walls located at both ends in the longitudinal direction of the space board and having a step difference with respect to the space board, and a slide holder to which the slider is coupled.

[0028] The above-mentioned rotating plate may be positioned to overlap with the space board in the direction of the rotation axis, and may be positioned not to overlap with the slide side wall and the slide holder.

[0029] A portion of the above slide sidewall may be in the shape of an arc centered on the rotation axis.

[0030] At least a portion of the slide sidewall may be positioned to overlap in a direction intersecting the rotation plate and the rotation axis.

[0031] The above-described rotating plate may include a bottom surface to which the rotation axis is coupled and which defines a surface intersecting the rotation axis, and an edge wall protruding from the edge of the bottom surface.

[0032] Additionally, the present disclosure further includes an axle holder that connects the rotation axis to the slide shelf, and the slide shelf may include a receiving portion positioned opposite to the rotation plate to accommodate the axle holder.

[0033] The above slide shelf further includes an axis hole through which the rotation axis passes, the diameter of the axis holder is larger than the diameter of the axis hole, and the receiving portion and the axis hole may be positioned to overlap in the direction of the rotation axis.

[0034] The above shelf base can be attached to and detached from the shelf of a home appliance.

[0035] The above shelf base can be formed integrally with the shelf of the home appliance.

[0036] Additionally, a rotary lathe according to another embodiment of the present disclosure comprises a lathe base, a slide lathe installed on the lathe base to translate about the lathe base, and a rotary plate installed on the slide lathe to rotate about a rotation axis about the slide lathe, wherein the length of the first direction of the rotary plate, which is the translational direction of the slide lathe, is shorter than the length of the second direction intersecting the first direction of the rotary plate, and further comprises a slider disposed at both ends of the second direction of the slide lathe and sliding on the lathe base.

[0037]

[0038] Specific details of other embodiments are included in the detailed description and drawings.

[0039] The present disclosure has the advantage that the rotating plate is installed on a shelf or rotated after being pulled forward relative to a shelf base integrated with the shelf, allowing the user to easily retrieve stored items stored at the rear end of the rotating plate from outside or at the front of the refrigerator's storage space.

[0040] In addition, the present disclosure has the advantage of efficiently utilizing the storage space at the rear of the shelf because the rotating shelf is pulled forward and rotated 180 degrees, so even if the user places a stored item at the rear of the rotating plate, it can be easily retrieved.

[0041] If the rotating plate is rotated in place, the length in the front-to-back direction and the length in the left-to-right direction of the rotating plate would be the same; however, in the present disclosure, the rotating plate is rotated after being withdrawn, so the length in the left-to-right direction of the rotating plate is formed to be longer than the length in the front-to-back direction, thereby maximizing the left-to-right length of the rotating plate and thus maximizing the space for placing items on the rotating shelf.

[0042] The present disclosure has the advantage that a slide shelf on a shelf base slides in the forward and backward direction by means of the connection between the slider and the side of the shelf base, and since the slider suppresses movement and shaking in the up and down direction, the rotating plate rotating on the slider shelf can rotate stably after the slider shelf moves forward.

[0043] The effects of the present disclosure are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description in the claims.

[0065] A singular expression includes a plural expression unless the context clearly indicates otherwise.

[0066] Before the explanation, directions are defined. In the embodiment of the present disclosure, the direction in which the front of the door shown in FIG. 1 faces can be defined as the front, the direction in which the cabinet faces relative to the front of the door can be defined as the rear, the direction in which the refrigerator is installed can be defined as the downward direction, and the direction away from the bottom surface can be defined as the upward direction.

[0067] FIG. 1 is a perspective view of a refrigerator (1) according to one embodiment of the present disclosure, and FIG. 2 is a front view of the storage space of the refrigerator shown in FIG. 1.

[0068] Referring to FIGS. 1 and 2, a refrigerator (1) according to an embodiment of the present disclosure may have an exterior formed by a cabinet (10) that forms a storage space (12, 13) and a door (20) that opens and closes the storage space (12, 13).

[0069] The storage space (12, 13) inside the cabinet (10) can be divided vertically by a partition wall (not shown), and a refrigerator room (12) can be formed in the upper part of the cabinet (10) and a freezer room (13) can be formed in the lower part of the cabinet (10).

[0070] The storage space (12, 13) can be divided vertically by the shelf (9). Specifically, the refrigerator room (12) can be divided vertically by the shelf (9). The shelf (9) extends in a direction parallel to the front-rear direction.

[0071] For example, the cabinet (10) may include a rear side (123) which is a surface facing the door (20), and a side (122) which extends from the edge of the rear side (123) and defines a surface that intersects the rear side (123). The side (122) may extend in the front-rear direction.

[0072] Also, a control unit (not shown) for controlling the overall operation of the refrigerator (1) may be formed on the upper surface of the cabinet (10).

[0073] Additionally, an output unit (not shown) is connected to the control unit to output the operating status of the refrigerator (1). An operation unit (not shown) is connected to the control unit to input operations for the operation of the refrigerator (1).

[0074] The door (20) may be composed of a refrigerator door (21) and a freezer door (22). The refrigerator door (21) may be configured to open and close the open front of the refrigerator (12) by rotation, and the freezer door (22) may be configured to open and close the open front of the freezer (13) by rotation. Meanwhile, the refrigerator door (21) may be called the upper door (20) as it is provided on the upper side, and the freezer door (22) may be called the lower door (20) as it is provided on the lower side.

[0075] Additionally, the refrigerator door (21) may be provided with a pair of left and right doors so that the refrigerator (12) is shielded by the pair of doors (21, 22). Additionally, the freezer door (22) may be provided with a pair of left and right doors so that the freezer (13) is opened and closed by the pair of doors (20). Of course, the freezer door (22) may be configured to be pull-out in a drawer-like manner as needed, and may be configured with one or more doors.

[0076] In the embodiment of the present disclosure, a refrigerator (1) is described as an example in which a bottom-freeze type refrigerator (1) with a freezer compartment (13) provided at the bottom is equipped with a French-type door (20) in which a pair of doors (20) rotate to open and close one space, but the present disclosure can be applied to any type of refrigerator (1) in which a camera module can be installed, regardless of the shape of the refrigerator (1).

[0077] Meanwhile, at least one of the pair of refrigerator doors (21) may be composed of a main door (40) and a sub-door (30). The main door (40) is rotatably mounted on the cabinet (10) to open and close the refrigerator room (12). Additionally, an opening (not shown) may be formed through the main door (40).

[0078] A sub-door (30) is provided in front of a main door (40) and can be rotatably mounted on the main door (40). The sub-door (30) can open and close an opening. Additionally, a viewing section (31) capable of viewing the inside of the opening may be formed in the sub-door (30). The viewing section (31) may be composed of at least one transparent panel and may optionally be configured to make the inside of the opening (41) visible. Additionally, if necessary, the viewing section (31) may be composed of a display device such as an LCD capable of screen output or a transparent LCD.

[0079] FIG. 3 is a drawing showing a rotating shelf (300) and a shelf placed within the storage space shown in FIG. 2, and FIG. 4 is a drawing showing the rotating shelf (300) shown in FIG. 3 combined with a bracket.

[0080] Referring to FIGS. 3 and 4, the storage space (12, 13) can be divided vertically by a rotating shelf (300). The rotating shelf (300) extends in a direction parallel to the front-rear direction. The rotating shelf (300) and the shelf (9) can be installed in the storage space (12, 13) by a bracket (19). The bracket may include a support bracket (192) that supports the rotating shelf (300) and an upper / lower bracket (191) to which the support bracket (192) is connected, which determines the upper / lower height of the support bracket (192). The upper / lower bracket (191) is connected to the cabinet (10). The support bracket (192) is height-adjustably connected to the upper / lower bracket (191).

[0081] Of course, as illustrated in FIG. 11, the rotating shelf (300) may be seated or installed on the shelf (9). The rotating shelf (300) may also be detachable from the shelf (9).

[0082]

[0083] The structure of the rotary shelf (300) is described in detail below.

[0084] FIG. 5 is a perspective view of the rotary shelf illustrated in FIG. 3, FIG. 6 is an exploded perspective view of the rotary shelf illustrated in FIG. 5, FIG. 7a is a cross-sectional perspective view taken along line 7a-7a' of the rotary shelf illustrated in FIG. 5, FIG. 7b is a cross-sectional perspective view taken along line 7b-7b' of the rotary shelf illustrated in FIG. 5, FIG. 8a is a perspective view of the sliding shelf illustrated in FIG. 5 in a state where it has been moved forward, FIG. 8b is a cross-sectional perspective view taken along line 8b-8b' of FIG. 8a, FIG. 9a is a perspective view of the sliding shelf illustrated in FIG. 5 in a state where it has been moved forward and the rotary plate (310) has been rotated 90 degrees, FIG. 9b is a cross-sectional view taken along line 9b-9b' of FIG. 9a.

[0085] Referring to FIGS. 5 and 6, a rotary lathe (300) according to one embodiment of the present disclosure includes a lathe base (330), a rotary plate (310), and a slide lathe (320). Additionally, the rotary lathe (300) according to one embodiment of the present disclosure may further include a slider (350) that guides the slide lathe (320) to slide.

[0086] In one embodiment of the present disclosure, the rotating shelf (300) can be rotated after the rotating plate (310) and the slide shelf (320) are pulled forward.

[0087] The shelf base (330) supports the slide shelf (320). The shelf base (330) is in a stationary state and can be attached to and detached from the shelf of the home appliance. As another example, the shelf base (330) may be formed integrally with the shelf of the home appliance. In this case, a bracket coupling part (339) to which a bracket is attached may be formed on the shelf base (330).

[0088] The shelf base (330) supports the rotating plate (310) and guides the slide shelf (320) without interfering when the slide shelf (320) is pulled forward, while allowing the slide shelf (320) to move back and forth, and restricting the slide shelf (320) to move left and right and up and down.

[0089] The slide shelf (320) is installed on the shelf base (330) and moves in translation relative to the shelf base (330). The slide shelf (320) may be guided directly by the shelf base (330), but it is preferable that it be guided by a slider (350).

[0090] A rotating plate (310) is rotatably coupled to the slide shelf (320). The rotating plate (310) moves together with the slide shelf (320) when the slide shelf (320) is translated.

[0091] The configuration of the shelf base (330) is described below.

[0092] Referring to FIGS. 6 to 8, for example, the shelf base (330) may have a space (322) in which a slide shelf (320) is accommodated. The space (322) in which the slide shelf (320) of the shelf base (330) is accommodated may have a shape in which at least the front and top are open. Accordingly, the slide shelf (320) located on the shelf base (330) can be moved in the forward and backward directions, and a rotating plate (310) can be located on the slide shelf (320).

[0093] Specifically, the shelf base (330) includes a plate-shaped base plate (331) and a sliding guide (333, 335) on which the slider (350) is guided.

[0094] The base plate (331) defines a surface that intersects the vertical direction, and a space (322) is defined on the upper side where the slide shelf (320) is positioned. The base plate (331) may be rectangular.

[0095] The sliding guides (333, 335) are positioned on the base plate (331) to guide the slider (350). Additionally, the sliding guides (333, 335) can guide the slide shelf (320). Specifically, the sliding guides (333, 335) can be positioned at both ends of one direction of the base plate (331).

[0096] More specifically, the sliding guides (333, 335) can be positioned at both ends of the base plate (331) in the left and right directions. When the sliding guides (333, 335) are positioned at both ends of the base plate (331) in the left and right directions, the sliding guides (333, 335) do not interfere with the slide shelf (320) when the slide shelf (320) moves in the forward and backward directions.

[0097] A base plate (331) defines the bottom surface of the shelf base (330), and a part of the sliding guide (333, 335) may define a part of the side of the shelf base (330). It is preferable that two sliding guides (333, 335) be positioned facing each other. Specifically, it may include a first sliding guide (333, 335) positioned at the left end of the shelf base (330) and a second sliding guide (334, 336) positioned at the right end of the shelf base (330).

[0098] For example, the sliding guide (333, 335) may include a top guide (335) and a horizontal guide (333). The top guide (335) may be positioned to face a part of the base plate (331). Specifically, the top guide (335) may be spaced upward from the base plate (331).

[0099] The horizontal guide (333) separates the top guide (335) and the base plate (331). The horizontal guide (333) connects the top guide (335) and the base plate (331). The lower end of the horizontal guide (333) is connected to either the left or right end of the base plate (331), and the upper end of the horizontal guide (333) can be connected to the top guide (335). The horizontal guide (333) may also define the left and right sides of the shelf base (330). The horizontal guide (333) may extend upward from both the left and right ends of the base plate (331).

[0100] The top guide (335) can extend from the horizontal guide (333) inwardly into the base plate (331). Thus, the top guide (335), the horizontal guide (333), and the part of the base plate (331) connected to the horizontal guide (333) can define a “C” shape that is open inwardly.

[0101] The vertical movement of the slider (350) or slide shelf (320) is restricted by a part of the base plate (331) connected to the top guide (335) and the horizontal guide (333), and the horizontal movement of the slide shelf (320) is restricted by the horizontal guides (333) positioned on both the left and right sides of the base plate (331).

[0102] Although the length of the horizontal guide (333) and the length of the top guide (335) may be the same, if the length of the horizontal guide (333) and the length of the top guide (335) are the same, when assembling the sliding shelf to the shelf base (330), it must be joined by inserting it from the front to the back, but there is a problem that assembly is difficult due to the limited space.

[0103] Therefore, it is preferable that the length of the horizontal guide (333) be longer than the length of the top guide (335). Specifically, the length of the horizontal guide (333) in the front-rear direction is longer than the length of the top guide (335) in the front-rear direction. At this time, the top guide (335) may be positioned so as to be offset toward the front of the horizontal guide (333). Since the rear end of the horizontal guide (333) is open at the top, a slider (350) or a part of a sliding shelf is inserted downward from the upper part of the rear end of the horizontal guide (333).

[0104] The horizontal guide (333) may have a step in the middle. This step sets a limit to the movement when the slider (350) moves forward and prevents the slider (350) from coming off.

[0105] The left and right thicknesses of the horizontal guide (333) may be the same in the front and rear directions, but the thickness of the front end of the horizontal guide (333) may be greater than the thickness of the rear end of the horizontal guide (332). Due to the difference in thickness of the horizontal guide (333), the slider (350) does not detach.

[0106] Specifically, as illustrated in FIG. 6, the horizontal guide (334) located at the right end of the shelf base (330) may include a first horizontal guide (334a) and a second horizontal guide (334b) located in front of the first horizontal guide (334a) and having a thicker thickness than the first horizontal guide (334a).

[0107] The slide shelf (320) translates between a first position and a second position in which the area overlapping with the shelf base (330) and the rotation axis (313) direction (up and down direction) is smaller than that of the first position.

[0108] Here, the first position is the position of FIG. 5, which means a position where the slide shelf (320) and the shelf base (330) are completely or almost completely overlapped in the vertical direction. The second position is the position of FIG. 8a, which means a position where the area where the slide shelf (320) and the shelf base (330) overlap in the vertical direction is smaller than that of the first position. That is, the second position is a position where the slide shelf (320) is pulled forward more than in the first position. The rotating plate (310) is rotated in the second position.

[0109] The top guide (335) can be positioned adjacent to the front end of the horizontal guide (333) in the horizontal guide (333). Accordingly, in the first position, the slide shelf (320) can be easily connected and disconnected in the vertical direction from the shelf base (330), and when the slide shelf (320) moves from the first position to the second position, movement in the vertical and horizontal directions is restricted, and it is guided in the front and rear directions.

[0110] The shelf base (330) may further include a base cover (337a) that is positioned at one end of the other direction of the base plate (331) and covers a portion of the rotating plate (310) at the first position.

[0111] The base cover (337a) is spaced above the base plate (331) to define a space where a rotating plate (310) is positioned between the base plate (331) and the base cover (337a). Specifically, the base cover (337a) may be positioned facing the rear end of the base plate (331). The length of the base cover (337a) in the front-rear direction may be shorter than that of the base plate (331).

[0112] More specifically, the shelf base (330) may further include a base rear (337). The base rear (337) extends upward from the rear end of the base plate (331). The base rear (337) is located between the base cover (337a) and the base plate (331). The upper end of the base rear (337) is connected to the base cover (337a), and the lower end of the base rear (337) is connected to the rear end of the base plate (331). The base cover (337a) protrudes forward from the upper end of the base rear (337).

[0113] Both ends of the rear of the base (337) can be connected to the rear ends of the horizontal guides (333). When both ends of the rear of the base (337) are connected to the rear ends of the horizontal guides (333), the warping of the shelf base (330) can be suppressed.

[0114] The shelf base (330) may be formed integrally with the shelf of the refrigerator. In this case, the shelf base (330) may have a bracket coupling portion (339) to which a bracket (19) is coupled. The bracket coupling portion (339) may be a groove to which the bracket (19) is coupled, or a screw hole to which a screw penetrating the bracket (19) is fastened.

[0115] Specifically, the bracket joint (339) may be a groove recessed in the left and right directions at the left and right ends of the shelf base (330).

[0116] The shelf base (330) may have a size and shape corresponding to the storage space (12) of the refrigerator. The shelf base (330) may be a rectangular plate corresponding to the horizontal cross-sectional shape of the storage space (12).

[0117] The shelf base (330) may further include a bracket insertion portion (338) into which a portion of the bracket (19) is inserted. The bracket insertion portion (338) defines a space into which a portion of the bracket (19) is inserted. Specifically, the bracket insertion portion (338) may define a space into which a portion of the bracket (19) is inserted between the lower surface of the base plate (331) and the base plate (331). More specifically, the bracket insertion portion (338) may have a structure that extends downward from the bottom of the base plate (331) and then extends outward.

[0118] The structure of the slide shelf (320) is described below.

[0119] The slide shelf (320) is installed on the shelf base (330) to translate relative to the shelf base (330). The slide shelf (320) may be directly guided to the shelf base (330), and a slider (350) may be coupled to the slide shelf (320) and the slider (350) may be guided to the shelf base (330).

[0120] The slide shelf (320) moves in a translational motion between a first position and a second position. That is, the slide shelf (320) moves in a translational motion in the forward and backward directions. Both ends of the slide shelf (320) can be connected to sliding guides (333, 335) to slide. However, as described below, it is preferable to guide through a slider (350). Below, a structure using a slider (350) will be described.

[0121] The slide shelf (320) has a structure that allows translational movement in the forward and backward directions on the shelf base (330) and supports rotation of the rotating plate (310).

[0122] For example, the slide shelf (320) may include a space board (321), a slide side wall (322), and a slide holder (326). Of course, the slide holder (326) may be omitted if the slider (350) is omitted.

[0123] The space board (321) provides a space on its upper surface where the rotating plate (310) rotates. The space board (321) further includes an axis hole (323) to which the rotation axis (313) of the rotating plate (310) is coupled. The axis hole (323) may be a hole formed by penetrating the space board (321).

[0124] The space board (321) has a plate shape and has a shape and size corresponding to the shelf base (330). Specifically, the space board (321) may be a rectangle in which the length in the left-right direction is longer than the length in the front-back direction. This shape of the space board (321) corresponds to the shape of the rotating plate (310), and is intended to secure a large storage space as the rotating plate (310) rotates.

[0125] The slide side walls (322) are located at both ends in the longitudinal direction of the space board (321) and have a step difference with the space board (321). The slide side walls (322) can protrude upward from both ends of the space board (321).

[0126] At least a portion of the slide side wall (322) may be positioned to overlap in a direction intersecting the rotation plate (310) and the rotation axis (313). Specifically, at least a portion of the slide side wall (322) may be positioned to overlap in the left-right direction.

[0127] It is preferable that the height of the top of the slide side wall (322) be the same as the height of the top of the rotating plate (310). If the height of the top of the slide side wall (322) is the same as the height of the top of the rotating plate (310), the side of the rotating plate (310) is not exposed to the outside when not rotating, thereby preventing the rotating plate (310) from rotating unnecessarily and preventing the rotating plate (310) from coming off.

[0128] A portion of the slide side wall (322) may have an arc shape centered on the rotation axis (313). Specifically, the inner surface of the slide side wall (322) may have an arc shape centered on the rotation axis (313). The arc shape of the slide side wall (322) corresponds to the hole shape of the rotation plate (310). Because the slide side wall (322) has an arc shape, when the rotation plate (310) is rotated, it does not interfere with both ends of the rotation plate (310) in the longitudinal direction, and the rotation plate (310) can have the widest storage area.

[0129] The slide holder (326) is coupled with the slider (350). The slide holder (326) may be part of the slide side wall (322). Alternatively, the slide holder (326) may protrude outward from the slide side wall (322). The slide holder (326) may have a shape that supports the slider (350) in the direction of gravity. The top of the slider (350) holder may have a step lower than the top of the slider (350) side wall.

[0130] The front-rear length of the slide holder (326) may be shorter than the front-rear length of the slide side wall (322). The slider (350) holder may be positioned adjacent to the rear end of the slide side wall (322).

[0131] In particular, referring to FIG. 9, the rotary shelf may also include an axle holder (325) that connects the rotation axis (313) to the slide shelf (320). The axle holder (325) is connected to the free end of the rotation axis (313), and a space board (321) of the slide shelf (320) is positioned between the axle holder (325) and the rotation plate (310).

[0132] The slide shelf (320) includes a receiving portion (329) that accommodates an axis holder (325) and is positioned opposite to the rotating plate (310). The receiving portion (329) is formed by being recessed upward from the lower surface of the space board (321) of the slide shelf (320).

[0133] The diameter of the shaft holder (325) is larger than the diameter of the shaft hole, and the receiving portion (329) and the shaft hole can be positioned to overlap in the direction of the rotation axis (313). Of course, the diameter of the rotation axis (313) may be smaller than the diameter of the shaft hole. If the diameter of the shaft holder (325) is larger than the diameter of the shaft hole, the shaft holder (325) is positioned in the receiving portion (329), preventing the rotation axis (313) from coming out of the shaft hole.

[0134] The rotating plate (310) is positioned to overlap with the space board (321) in the direction of the rotation axis (313) and not to overlap with the slide side wall (322) and the slide holder (326). That is, the rotating plate (310) is positioned to overlap with the space board (321) in the vertical direction and not to overlap with the slide side wall (322) and the slide holder (326).

[0135] The slide shelf (320) may further include a stopper (327) that limits the forward and backward movement of the slide shelf (320). The stopper (327) contacts the shelf base (330) to define the limit of the backward movement of the slide shelf (320). Specifically, the stopper (327) may be formed to protrude in the left and right directions from the front end of the slide shelf (320).

[0136] The structure of the slider (350) is described below.

[0137] Referring again to FIGS. 6 through 8, the slider (350) is coupled to the slide shelf (320) and slides on the shelf base (330). Specifically, the slider (350) is coupled to the slide holder (326). The slider (350) holder can be positioned on the left and right sides of the slide shelf (320).

[0138] The slider (350) slides in the space between the top guide (335) and the base plate (331). The space between the top guide (335) and the base plate (331) extends in the front-rear direction, and the slider (350) is guided in the front-rear direction.

[0139] Specifically, the slider (350) includes a vertical slider (352) that contacts the top guide (335) and base plate (331) to restrict vertical movement, and a horizontal slider (353) that separates the vertical slider (352) from the horizontal guide (333).

[0140] The vertical slider (352) has a height corresponding to the distance between the top guide (335) and the base plate (331). The vertical slider (352) is inserted into the space between the top guide (335) and the base plate (331) and slides back and forth.

[0141] A horizontal slider (353) may protrude from the vertical slider (352) to separate the vertical slider (352) from the horizontal guide (333). Since the vertical slider (352) extends in the forward and backward directions and the length in the upward direction is longer than the length in the left and right directions, friction increases when the side of the vertical slider (352) and the horizontal guide (333) come into surface contact, so a horizontal slider (353) is required to separate the vertical slider (352) from the horizontal guide (333).

[0142] The vertical length of the horizontal slider (353) may be shorter than the vertical length of the vertical slider (352). Additionally, to reduce the contact area, the horizontal slider (353) may have a narrower width as it moves away from the vertical slider (352), or the free end may be rounded.

[0143] Meanwhile, the slider (350) may further include a fastening portion (351) to which a fastening member is coupled for fastening the vertical slider (352) to the sliding shelf. A fastening hole (351a) through which the fastening member passes may be formed in the fastening portion (351). Specifically, a screw passes through the fastening hole (351a) and is coupled to the slide holder (326).

[0144] The fastening portion (351) may be supported on the slider (350) holder. The fastening portion (351) may be supported on the top of the slider (350) holder. Additionally, a portion of the fastening portion (351) may be supported on the side of the slider (350) holder.

[0145] The length of the slider (350) is not limited, but it may have a length that facilitates easy connection from top to bottom when the rotating plate (310) is positioned at the rear (first position) and allows stable guidance when the slide shelf (320) moves from the rear to the front.

[0146] Specifically, the front-rear length of the slider (350) may be shorter than the front-rear length of the slide shelf (320) and the horizontal guide (333). More specifically, the front-rear length of the slider (350) may be shorter than the distance between the rear end of the horizontal guide (333) and the rear end of the top guide (335).

[0147] If the front-to-back length of the slider (350) is shorter than the distance between the rear end of the horizontal guide (333) and the rear end of the top guide (335), the slider (350) can be easily connected and separated in the up-and-down direction through the rear end of the shelf base (330) where the top guide (335) is not formed.

[0148] The structure of the rotating plate (310) is described in detail below.

[0149] The rotating plate (310) is positioned on the shelf base (330) and rotates relative to the slide shelf (320). Thus, the slide shelf (320) is withdrawn from the shelf base (330), and the rotating plate (310) is rotated 180 degrees, allowing the stored item located at the rear end of the rotating plate (310) to be easily removed. The rotating plate (310) is rotated at a second position on the slide shelf (320).

[0150] The rotating plate (310) is installed on the slide shelf (320). The rotating plate (310) may include a rotation axis (313). For example, the rotation axis (313) may be coupled to the rotating plate (310). Of course, for another example, the rotation axis (313) may be formed integrally with the rotating plate (310). The rotation axis (313) may extend downward from the lower surface of the rotating plate (310). The rotation axis (313) may extend parallel to the up and down direction. The rotation axis (313) becomes the rotation center of the rotating plate (310).

[0151] The rotation axis (313) may have a structure that prevents it from being dislodged from the slide shelf (320). As described above, the rotation axis (313) is inserted into the shaft hole (323) of the slide shelf (320) and has a structure in which it is prevented from being dislodged by the shaft holder (325).

[0152] The rotating plate (310) has a shape that maximizes storage space and does not interfere with the storage space of the refrigerator when rotated.

[0153] For example, the length of the first direction, which is the translational motion direction of the slide shelf (320) of the rotating plate (310), may be shorter than the length of the second direction that intersects the first direction of the rotating plate (310). Specifically, the length of the slide front-back direction of the rotating plate (310) may be shorter than the length of the left-right direction of the rotating plate (310).

[0154] The rotating plate (310) includes a bottom surface (311, 312) that defines a surface intersecting the rotating axis (313) and to which the rotating axis (313) is coupled, and an edge wall (314, 315) that protrudes from the edge of the bottom surface (311, 312).

[0155] The bottom surface (311, 312) may include a first region (312) where a rotation axis (313) is formed, and a second region (311) having a step difference from the first region (312). The first region (312) may have a lower height than the second region (311). The second region (311) may be located at both ends in the longitudinal direction of the first region (312).

[0156] A plate cover (316) may be positioned in the first area (312). The plate cover (316) covers the rotation axis (313) of the rotating plate (310).

[0157] The edge walls (314, 315) of the rotating plate (310) may protrude above the first area (312) and the second area (311). The edge walls (314, 315) of the rotating plate (310) may indicate to the user the limit on which items can be placed on the rotating plate (310) and provide a grip when the user rotates the rotating plate (310).

[0158] The rotating plate (310) may have a rectangular shape. Specifically, the rotating plate (310) may include a long edge (315) facing in a first direction and a short edge (314) facing in a second direction. That is, the rotating plate (310) may have two long edges (315) spaced apart in the front-rear direction and extended in the left-right direction. The two short edges (314) may connect each end of the two long edges (315) and be spaced apart from each other in the left-right direction.

[0159] The long edge (315) may be a straight shape, and the short edge (314) may be an arc shape centered within the rotating plate (310). The short edge (314) may be an arc shape located on a circumference centered on the axis of rotation (313). The long edge (315) may be located inside any circumference centered on the axis of rotation (313). Of course, the long edge (315) and the short edge (314) may form part of the edge wall. Thus, due to the arc shape of the short edge (314), interference with the slide side wall (322) and the shelf base (330) can be eliminated.

[0160]

[0161] The operation of the rotary lathe (300) of the present disclosure is described below.

[0162] FIGS. 10a to 10f are drawings illustrating the operation of a rotary lathe (300) according to one embodiment of the present disclosure.

[0163] Referring to FIG. 10a, the slide shelf (320) is positioned in a first position so as to be completely overlapped with the shelf base (330) in a vertical direction.

[0164] Referring to FIG. 10b, in the state of FIG. 10a, when the user grasps the edge of the rotating plate (310) and pulls the rotating plate (310) forward, the slide shelf (320) and the rotating plate (310) are moved forward (second position).

[0165] At this time, the distance (E) by which the rotating plate (310) is moved forward is smaller than the front-rear length (L) of the rotating plate (310). More preferably, the distance (E) by which the rotating plate (310) is moved forward is smaller than 60% of the front-rear length (L) of the rotating plate (310). This is because if the rotating plate (310) moves forward too much, the center of gravity of the rotating plate (310) and the slide shelf (320) will shift toward the front of the shelf base (330), and the rotating shelf may overturn.

[0166] The diameter (D) of the short edge (314) of the rotating plate (310) is greater than the front-rear length (L) of the rotating plate (310). This is because if the diameter (D) of the short edge (314) of the rotating plate (310) is greater than the front-rear length (L) of the rotating plate (310), the rotation limit of the rotating plate (310) is determined by the diameter (D) of the short edge (314).

[0167] Referring to FIG. 10c, with the rotating plate (310) (410) and the slide shelf (320) moved to a second position, the rotating plate (310) is rotated. The rotating plate (310) rotates relative to the slide shelf (320) and the rotating base.

[0168] Referring to FIG. 10d, when the rotating plate (310) (410) is rotated 180 degrees relative to its initial position, the storage at the rear end of the rotating plate (310) is moved forward, and the user can easily take out the storage located at the rear.

[0169] Referring to FIG. 10e, in the second position, the rotating plate (310) is rotated. The rotating plate (310) rotates relative to the slide shelf (320) and the rotating base.

[0170] Referring to FIG. 10f, the rotating plate (310) is rotated 180 degrees relative to FIG. 10d.

[0171] Referring to FIG. 10g, when the rotating plate (310) is rotated 180 degrees, the rotating plate (310) and the slide shelf (320) are moved backward. The rotating plate (310) and the slide shelf (320) return to the initial position of FIG. 10a.

[0172] In conclusion, the rotating plate (310) is moved forward, then rotated 180 degrees, then rotated 180 degrees again, and then moved backward.

[0173]

[0174] Below, other rotary lathes in other embodiments are described in detail.

[0175] FIG. 11 is a drawing showing a rotating shelf according to another embodiment (second embodiment) of the present disclosure installed on a shelf of a refrigerator, and FIG. 12 is an exploded perspective view of the rotating shelf of FIG. 11.

[0176] The embodiment of FIG. 11 differs from the embodiments of FIG. 1 to FIG. 10 (first embodiment) in that the rotating shelf (300') is coupled to the shelf of the refrigerator.

[0177] The rotating shelf (300') may be seated or installed on the shelf (9). The rotating shelf (300') may also be detachable from the shelf (9). The rotating shelf (300') may be attached or connected to the upper surface of the shelf (9) by means of an adsorption member (390) or a coupling member.

[0178] The suction member (390) can be attached to the bottom of the shelf base (330). It is preferable that 2 to 4 suction members (390) be placed on the shelf base (330). The suction member (390) is suctioned to the upper surface of the shelf (9) of the refrigerator.

[0179] The shelf base (330) may have a size and shape corresponding to the shelf (9) of the refrigerator. Specifically, the shelf (9) of the refrigerator may be rectangular. Of course, the shelf base (330) may have a smaller size than the shelf (9) of the refrigerator so that the rotating shelf (300') can be easily detached from the shelf (9) of the refrigerator.

[0180] In the shelf base (330) of the second embodiment, the bracket connecting part (339) is omitted compared to the first embodiment.

[0181]
