Description

Rotary lathe and home appliances including the same

[0001] The present disclosure relates to a rotating shelf and a home appliance including the same, and more particularly, to a rotating shelf and a home appliance that enable easy removal of stored items stored at the rear of the shelf and utilization of the storage space at the rear of the shelf.

[0002] A refrigerator, a common household appliance, is a device that allows food to be stored at low temperatures within an internal storage space enclosed by a door. To achieve this, refrigerators utilize the cold air generated through heat exchange with the refrigerant circulating in the refrigeration cycle to cool the interior of the storage space, thereby maintaining optimal storage conditions for stored food.

[0003] To efficiently utilize the entire refrigerator storage space, shelves are used to divide the storage space vertically. While these shelves increase the vertical usability of the storage space, they also make it difficult for users to access items located at the rear of the shelf. Therefore, items are stored only at the front of the shelf, reducing the usability of the storage space in the front-to-back direction.

[0004] In the case of patent document 1, a shelf of a general refrigerator is disclosed, but in this case, when storing items at the rear end of the shelf, there is a problem that it is difficult to take out the items placed at the rear end of the shelf.

[0005] In the case of patent document 2, it is characterized by at least one carrier plate (3) having a bearing area (5) and a shelf (2) that can rotate and translate on the bearing area (5) of the carrier plate (3), but there is a problem that the rotation and translational movement are not smooth due to the complex structure of the bearing area, and the shelf can be easily separated from the carrier plate.

[0007] (Patent Document 0001) Republic of Korea Publication Patent No. 10-2011-0002589

[0008] (Patent Document 0002) Republic of Korea Publication No. 10-2019-0130600

[0009] The purpose of the present disclosure is to provide a rotating shelf that allows a user to easily take out stored items placed at the rear end of the shelf, and an appliance including the same.

[0010] Another object of the present disclosure is to provide a rotating shelf and an appliance that efficiently utilizes 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 home appliance including the same, wherein a rotating plate is rotated while being pulled out onto a shelf base to maximize the length of the rotating plate and thereby secure storage space.

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

[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-mentioned purpose is characterized in that a rotary plate installed on a lathe base is moved forward while rotating from 0 to 90 degrees by a guide cam, and is moved backward while rotating from 90 to 180 degrees.

[0015] Specifically, a rotary lathe according to one aspect of the present disclosure includes a lathe base, a rotary plate positioned on the lathe base and configured to rotate and translate with respect to the lathe base, the rotary plate including a rotational axis and a guide projection, and a guide cam installed on the lathe base to guide the rotational plate to rotate and translate, wherein the guide cam is characterized in that it includes an axis guide portion that guides the rotational axis to rotate and move in a first direction, and a guide surface that guides the guide projection.

[0016] The above guide projection includes a first guide projection and a first guide projection spaced apart from the first guide projection, and the rotation axis may be located between the first guide projection and the second guide projection.

[0017] The above rotation axis, the first guide projection, and the second guide projection can be arranged on any straight line.

[0018] The guide surface may include a guide inclined surface that guides the guide projection to move in a straight line in a direction intersecting the first direction, and a guide curved surface that guides the guide projection to rotate at a certain angle with respect to an arbitrary center.

[0019] The above guide inclined surface can be connected to one end of the above guide curved surface.

[0020] The above guide inclined surface may include a first guide inclined surface that guides the guide projection to move in a straight line in a second direction intersecting the first direction, and a second guide inclined surface that guides the guide projection to move in a straight line in a third direction intersecting the first direction.

[0021] The angle formed by the first guide inclined surface and the second guide inclined surface may be an acute angle.

[0022] The above-mentioned shaft guide portion may be located between the first guide inclined surface and the second guide inclined surface.

[0023] The first guide inclined surface and the second guide inclined surface may be arranged symmetrically with respect to the axis guide portion.

[0024] The above guide surface may be an arc shape centered on the shear rotation point of the shaft guide portion.

[0025] The above guide surface includes a first guide surface and a second guide surface spaced apart from the first guide surface, and at least a portion of the axial guide portion can be positioned between the first guide surface and the second guide surface.

[0026] The radius of curvature of the guide surface may be equal to the distance between the axis of rotation and the guide projection.

[0027] The above rotating plate may further include a first region where the rotating shaft and the guide protrusion are coupled, and a second region having a step from the first region, and a plate cover covering the first region.

[0028] Additionally, the present disclosure may further include a rear guide installed on the shelf base and guiding the outer surface of the rotating plate.

[0029] The above rear guide can be extended in a direction perpendicular to the above first direction.

[0030] The above-mentioned shaft guide may be a hole formed by penetrating a part of the guide cam.

[0031] The above-mentioned rotating shaft may include a first shaft portion and a second shaft portion connected to the lower end of the first shaft portion, having a diameter that is expanded compared to the first shaft portion.

[0032] The width of the shaft guide portion may be smaller than the diameter of the second shaft portion and larger than the diameter of the first shaft portion.

[0033] The above shelf base can be attached to and detached from the shelf of a home appliance.

[0034] The above shelf base can be formed integrally with the shelf of the home appliance.

[0035] In addition, a home appliance according to another embodiment of the present disclosure includes a cabinet forming a storage space, a door for opening and closing the storage space, and at least one rotating shelf for dividing the storage space, wherein the rotating shelf includes a shelf base, a rotating plate positioned on the shelf base and configured to rotate and translate with respect to the shelf base, and a guide cam installed on the shelf base for guiding the rotating plate to rotate and translate, wherein the guide cam moves the rotating plate forward while the rotating plate rotates from 0 degrees to 90 degrees, and moves the rotating plate backward while the rotating plate rotates from 90 degrees to 180 degrees.

[0036]

[0037] Specific details of other embodiments are included in the detailed description and drawings.

[0038] The present disclosure has the advantage that the rotating plate is installed on a shelf or is pulled out while rotating relative to a shelf base integrated with the shelf, allowing the user to easily retrieve the stored items stored at the rear end of the rotating plate from outside or at the front end of the storage space of the home appliance.

[0039] The present disclosure has the advantage of efficiently utilizing the storage space at the rear of the shelf, as the rotating shelf is pulled out while rotating 180 degrees, so even if the user places the stored item at the rear of the rotating plate, it can be easily retrieved.

[0040] If the rotating plate rotates 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 rotates while being pulled out, 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 providing the advantage of securing storage space.

[0041] In this disclosure, the rotation axis of a rotating plate is coupled to a guide cam of a shelf base to enable translational and rotational motion, and the guide projection of the rotating plate is guided along the outer surface of the guide cam. Since the rotational and translational motion of the rotating plate is guided using a single cam, there are advantages of guiding the rotating plate with a simple structure, reducing manufacturing costs, and improving structural rigidity and reliability.

[0042] The effects of the present disclosure are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0080] FIG. 3 is a drawing showing a rotating shelf (400) and a shelf placed within the storage space shown in FIG. 2, and FIG. 4 is a drawing showing the rotating shelf (400) shown in FIG. 3 combined with a bracket.

[0081] Referring to FIGS. 3 and 4, storage spaces (12, 13) can be divided vertically by a rotating shelf (400). The rotating shelf (400) extends in a direction parallel to the front-rear direction. The rotating shelf (400) and the shelf (9) can be installed in the storage spaces (12, 13) by a bracket (19). The bracket may include a support bracket (192) that supports the rotating shelf (400) 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).

[0082] Of course, as illustrated in FIG. 11, the rotating shelf (400) may be seated or installed on the shelf (9). The rotating shelf (400) may also be detachable from the shelf (9).

[0083]

[0084] The structure of the rotary shelf (400) is described in detail below.

[0085] FIG. 5 is a perspective view of the rotary lathe (400) illustrated in FIG. 3, FIG. 6 is an exploded perspective view of the rotary lathe (400) illustrated in FIG. 5, and FIG. 7 is a cross-sectional view taken along the 5-5' line of the rotary lathe (400) illustrated in FIG. 5.

[0086] Referring to FIGS. 5 to 7, a rotary lathe (400) according to one embodiment of the present disclosure includes a lathe base (410), a rotary plate (440), and a guide cam (420).

[0087] A rotating shelf (400) according to one embodiment of the present disclosure may be rotated as the rotating plate (440) is withdrawn forward from the shelf base (410), and may be rotated after the withdrawal is completed.

[0088] The shelf base (410) provides a place where the guide cam (420) is installed and supports the rotating plate (440).

[0089] The shelf base (410) 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 (410) may be formed integrally with the shelf of the home appliance. In this case, a bracket coupling part (415) to which a bracket is attached may be formed on the shelf base (410).

[0090] The shelf base (410) supports the rotating plate (440) and can avoid interference when the rotating plate (440) is pulled forward.

[0091] For example, the shelf base (410) may include a plate-shaped base plate (411) and a rear guide joint (413) protruding from the rear end of the base plate (411).

[0092] The base plate (411) is coupled with a guide cam (420). The base plate (411) may include a cam coupling portion (412) to which the guide cam (420) is coupled.

[0093] The rear guide coupling part (413) is coupled with the rear guide (450) described later. Of course, depending on the embodiment, the rear guide (450) may be omitted, and the rear guide coupling part (413) itself may set a rearward movement limit of the rotation plate (440) and guide the outer surface of the rotation plate (440) during the rotation and parallel movement of the rotation plate (440).

[0094] The rear guide coupling portion (413) can extend in a left-right direction intersecting with the front-back direction. The rear guide coupling portion (413) can protrude upward from the base plate (411).

[0095] The present disclosure may further include a rear guide (450). The rear guide (450) sets a rear limit line of the rotating plate (440) and guides the outer surface of the rotating plate (440) during the rotation and translational movement of the rotating plate (440).

[0096] The rear guide (450) may be formed integrally with the shelf base (410). Preferably, as shown in FIG. 6, the rear guide (450) may be coupled to the shelf base (410) via a rear guide coupling portion (413). The rear guide (450) may include a groove (451) into which the rear guide coupling portion (413) is inserted.

[0097] The rear guide (450) can extend in a direction perpendicular to the first direction. The rear guide (450) can extend in the left and right directions.

[0098] The shelf base (410) may further include a side step portion (414) having a step from the base plate (411). The side step portion (414) may be formed to surround a portion of the side of the rotation plate (440).

[0099] The rotating plate (440) is positioned on the shelf base (410) and rotates and translates with respect to the shelf base (410). Therefore, when the rotating plate (440) is pulled out, it rotates 180 degrees, so that the stored material positioned at the rear end of the rotating plate (440) can be easily taken out.

[0100] The rotating plate (440) may include a rotating shaft (430, R) and guide protrusions (W1, W2). For example, the rotating shaft (430, R) and the guide protrusions (W1, W2) may be coupled to the rotating plate (440). Of course, as another example, the rotating shaft (430, R) and the guide protrusions (W1, W2) may be formed integrally with the rotating plate (440).

[0101] The rotating plate (440) may include a shaft coupling portion (447) to which a rotating shaft (430, R) is coupled, and a projection coupling portion (445, 446) to which a guide projection (W1, W2) is coupled. The rotating shaft (430, R) and the guide projection (W1, W2) may be rotatably coupled to the rotating plate (440).

[0102] The guide protrusions (W1, W2) may include a plurality of them. Preferably, there may be two guide protrusions (W1, W2).

[0103] For example, the guide protrusions (W1, W2) may include a first guide protrusion (W1) and a first guide protrusion (W1) spaced apart from the first guide protrusion (W1).

[0104] The rotation axis (430, R) becomes the rotation center of the rotation plate (440). The rotation axis (430, R) can be located between the first guide protrusion (W1) and the second guide protrusion (W2).

[0105] The rotation axis (430, R), the first guide protrusion (W1), and the second guide protrusion (W2) can be arranged on any straight line. The first guide protrusion (W1) and the second guide protrusion (W2) can be arranged symmetrically with respect to the rotation axis (430, R). The first guide protrusion (W1) and the second guide protrusion (W2) can be arranged spaced apart from the rotation axis (430, R) by the same distance.

[0106] The rotation shaft (430, R) can be installed to be rotatable and translationally movable on the guide cam (420). The rotation shaft (430, R) may have a structure that does not separate from the guide cam (420). For example, the rotation shaft (430, R) may include a first shaft portion (432) and a second shaft portion (431) that has a diameter larger than that of the first shaft portion (432) and is connected to the lower end of the first shaft portion (432).

[0107] The guide cam (420) can limit the vertical movement of the second axis (431) and allow the forward and backward movement.

[0108] The rotating plate (440) may include a first region (441) where a rotation axis (430, R) and a guide protrusion (W1, W2) are coupled, and a second region (442) having a step from the first region (441). The first region (441) may have a lower height than the second region (442).

[0109] A plate cover (448) can be positioned in the first region (441). The plate cover (448) covers the shaft coupling portion (447) and the protrusion coupling portions (445, 446) of the rotating plate (440).

[0110] The edge (443) of the rotating plate (440) may protrude upwards from the first region (441) and the second region (442). The edge (443) of the rotating plate (440) may inform the user of the limit of the items that can be stored on the rotating plate (440).

[0111] The rim (443) of the rotating plate (440) can be wrapped by a rim bumper (444). The rim bumper (444) provides cushioning between the rim (443) of the rotating plate (440) and the rear guide (450). The rim bumper (444) is ring-shaped and has a space (444a) formed inside to accommodate the rotating plate (440).

[0112] The rotating plate (440) may have a rectangular shape. Specifically, the rotating plate (440) may include a front end and a rear end that are parallel and spaced apart from each other, a left curved surface connecting the front end and the rear end, and a right curved surface connecting the front end and the rear end.

[0113] The left curved surface and the right curved surface may be located on any circumference centered on the rotation axis (430, R). The front and rear cross-sections may be located inside any circumference centered on the rotation axis (430, R).

[0114] FIG. 8 is a plan view of the guide cam (420) illustrated in FIG. 6.

[0115] Referring to FIGS. 6 to 8, a guide cam (420) is installed on a shelf base (410) to guide the rotation plate (440) to rotate and translate. The guide cam (420) can guide the translational movement of the rotation axis (430, R) and guide the linear and rotational movement of the guide projections (W1, W2).

[0116] The guide cam (420) can move the rotating plate (440) forward while the rotating plate (440) rotates from 0 to 90 degrees (Figs. 10a, 10b), and move the rotating plate (440) backward while the rotating plate (440) rotates from 90 to 180 degrees (Figs. 10c to 10e).

[0117] For example, the guide cam (420) may include an axis guide portion (421) and guide surfaces (425, 426, 427, 428).

[0118] While the rotating plate (440) rotates from 0 to 90 degrees (Figs. 10a, 10b), the rotation axis (430, R) is guided by the axis guide part (421) and moves forward while rotating, and the guide surfaces (425, 426, 427, 428) guide the rotation axis (430, R) to orbit as one of the guide protrusions (W1, W2) moves forward.

[0119] While the rotating plate (440) rotates from 90 degrees to 180 degrees (Figs. 10c to 10e), the rotation axis (430, R) is guided by the axis guide part (421) and moves backward while rotating, and the guide surfaces (425, 426, 427, 428) guide the rotation axis (430, R) to orbit as one of the guide protrusions (W1, W2) moves backward.

[0120] The shaft guide part (421) guides the rotation shaft (430, R) to rotate and move in the first direction.

[0121] The shaft guide portion (421) may be a hole formed by penetrating a part of the guide cam (420). The shaft guide portion (421) may be an elongated hole extending in a first direction. Specifically, the shaft guide portion (421) may be extended in a front-rear direction.

[0122] Specifically, the front end of the shaft guide (421) may be open, and the rear end of the shaft guide (421) may be closed. The front end of the shaft guide (421) may have an opening (422) having a width smaller than the diameter of the rotation axis (430, R) to prevent the rotation axis (430, R) from coming loose.

[0123] The width of the shaft guide portion (421) may be smaller than the diameter of the second shaft portion (431) and larger than the diameter of the first shaft portion (432). An insertion space (421a) into which the second shaft portion (431) is inserted may be formed between the shaft guide portion (421) and the base plate (411) of the shelf base (410). Accordingly, the rotation axis (430, R) can be rotated while moving back and forth along the shaft guide portion (421).

[0124] The guide surfaces (425, 426, 427, 428) guide the guide projections (W1, W2). The guide surfaces (425, 426, 427, 428) can guide the linear movement of the guide projections (W1, W2) and the rotational movement of the guide projections (W1, W2). The guide surfaces (425, 426, 427, 428) can form some of the outer surfaces of the guide cam (420).

[0125] For example, the guide surface (425, 426, 427, 428) may include a guide inclined surface (425, 426) and a guide curved surface (427, 428).

[0126] The guide inclined surface (425, 426) guides the guide projection (W1, W2) to move in a straight line in a direction that intersects the first direction.

[0127] The guide inclined surface (425, 426) can be connected to one end of the guide curved surface (427, 428). Specifically, the front end of the guide inclined surface (425, 426) can be connected to the rear end of the guide curved surface (427, 428).

[0128] The guide inclined surface (425, 426) may include a first guide inclined surface (425, A2) that guides the guide projection (W1, W2) to move in a straight line in a second direction that intersects the first direction, and a second guide inclined surface (426, A3) that guides the guide projection (W1, W2) to move in a straight line in a third direction that intersects the first direction.

[0129] The second and third directions may have slopes that move away from each other as they move forward. The second direction may be the direction between the front and the right, and the third direction may be the direction between the front and the left.

[0130] The angle formed by the first guide slope (425, A2) and the second guide slope (426, A3) may be an acute angle. Preferably, the angle formed by the first guide slope (425, A2) and the second guide slope (426, A3) may be greater than 45 degrees and less than 90 degrees.

[0131] The rear end of the first guide slope (425, A2) and the rear end of the second guide slope (426, A3) can be connected to each other. A curved portion (424, A0) having a curvature can be formed at the connection portion of the first guide slope (425, A2) and the second guide slope (426, A3).

[0132] The shaft guide portion (421) may be positioned between the first guide slope (425, A2) and the second guide slope (426, A3). Specifically, the first guide slope (425, A2) and the second guide slope (426, A3) may be arranged symmetrically with respect to the shaft guide portion (421). The shaft guide portion (421) may be positioned to overlap the curved portion (424) in the front-rear direction.

[0133] The rear end of the first guide slope (425, A2) and the rear end of the second guide slope (426, A3) can be positioned further rearward than the rear end of the shaft guide portion (421).

[0134] The guide slope (425, 426) guides the guide protrusions (W1, W2) when the rotation axis (430, R) moves along the shaft guide portion (421).

[0135] The guide surfaces (427, 428) guide the guide protrusions (W1, W2) to rotate at a certain angle based on an arbitrary center. For example, the guide surfaces (427, 428) may have an arc shape centered on the front rotation point (O) of the shaft guide portion (421). The front rotation point (O) of the shaft guide portion (421) refers to the rotation center of the rotation axis (430, R) when the rotation axis (430, R) is positioned at the frontmost position in the shaft guide portion (421).

[0136] That is, the guide curved surface (427, 428) may be a part of a circumference (A4) centered on the shear rotation point (O) of the shaft guide portion (421). When the guide curved surface (427, 428) has an arc shape, the central angle of the arc may be an acute angle. Preferably, when the guide curved surface (427, 428) has an arc shape, the central angle of the arc may be greater than 45 degrees and less than 90 degrees.

[0137] Specifically, the guide surface (427, 428) may include a first guide surface (427, A41) and a second guide surface (428, A42) spaced apart from the first guide surface (427, A41). At this time, at least a portion of the shaft guide portion (421) may be positioned between the first guide surface (427, A41) and the second guide surface (428, A42). The front end of the shaft guide portion (421) may be positioned between the first guide surface (427, A41) and the second guide surface (428, A42).

[0138] The guide cam (420) may further include a connecting surface (423) that connects the opening (422) of the axis guide portion (421) and the guide curved surface (427, 428). The connecting surface (423) provides a space where the guide protrusions (W1, W2) are positioned when the rotating plate (440) is housed in the rotating base.

[0139] The connecting surface (423) may include a first connecting surface (423a) connecting the right front end of the opening (422) of the shaft guide part (421) and the front end of the first guide curved surface (427, A41), and a second connecting surface (423b) connecting the left front end of the opening (422) of the shaft guide part (421) and the front end of the second guide curved surface (428, A42). The first connecting surface (423a) and the second connecting surface (423b) may have a slope that becomes closer as they move toward the rear.

[0140] The distance between the first connecting surface (423a) and the second connecting surface (423b) and the shear rotation point (O) of the shaft guide portion (421) may be smaller than the distance between the first guide curved surface (427, A41) and the second guide curved surface (428, A42) and the shear rotation point (O) of the shaft guide portion (421).

[0141] FIG. 9 is a conceptual diagram of a rotary lathe (400) according to one embodiment of the present disclosure.

[0142] Referring to FIGS. 7 to 9, the radius of curvature (D2 / 2) of the guide curved surface (427, 428) may be equal to the distance (L2 / 2) between the rotation axis (430, R) and the guide protrusions (W1, W2). That is, the diameter (D2) of the circumference (A4) defined by the guide curved surface (427, 428) may be equal to the distance (L2) between the first guide protrusion (W1) and the second guide protrusion (W2).

[0143] Accordingly, when the rotation axis (430, R) rotates around the shear rotation point (O) of the shaft guide portion (421), the guide protrusions (W1, W2) can be guided along the guide curved surfaces (427, 428).

[0144] The front-back length (L1) of the rotating plate (440) may be greater than the distance (L2) between the first guide protrusion (W1) and the second guide protrusion (W2). The diameter (D1) of the rotating plate (440) may be greater than the front-back length (L1) of the rotating plate (440).

[0145] The diameter (D1) of the rotating plate (440) is larger than the front-back length (L1) of the rotating plate (440), so that the rotating plate (440) cannot rotate in place, but moves forward by the distance that the rotating shaft (430, R) moves to rotate. The moving distance of the rotating shaft (430, R) may be a value obtained by subtracting the front-back length (L1) of the rotating plate (440) from the diameter (D1) of the rotating plate (440) and dividing it by 2. When the rotating plate (440) is pulled out, the moving distance of the rotating shaft (430, R) corresponds to the front-back length of the shaft guide part (421).

[0146]

[0147] Hereinafter, the operation of the rotary lathe (400) of the present disclosure will be described in detail.

[0148] FIGS. 10A to 10E are drawings illustrating a rotary lathe (400) in operation according to one embodiment of the present disclosure.

[0149] Referring to FIG. 10a, in the storage state of FIG. 9, when the user holds the edge of the rotating plate (440) and pulls the left or right end of the rotating plate (440), the rotating plate (440) rotates and moves forward.

[0150] The first guide protrusion (W1) comes into contact with the rear end of the first guide slope (425, A2), and the first edge of the rotating plate (440) moves to the right along the rear guide (450) (A1).

[0151] The rotation axis (430, R) is moved from the rear end of the shaft guide part (421) to the middle of the shaft guide part (421).

[0152] Referring to Fig. 10b, when the rotation plate (440) rotates, the first guide protrusion (W1) moves to the left front along the first guide slope (425, A2), and the first edge of the rotation plate (440) moves to the right along the rear guide (450) (A1). The first guide protrusion (W1) becomes adjacent to the rear end of the first guide curved surface (427, A41).

[0153] The rotation axis (430, R) moves from the stop of the shaft guide part (421) to the front end of the shaft guide part (421).

[0154] The second guide protrusion (W2) is adjacent to the front end of the second guide curved surface (428, A42) in front of the shaft guide portion (421).

[0155] Referring to Fig. 10c, as the rotating plate (440) continues to rotate, the first guide protrusion (W1) rotates along the first guide curved surface (427, A41). The first guide protrusion (W1) is guided from the rear end to the front end of the first guide curved surface (427, A41).

[0156] The rotation axis (430, R) rotates at the front end of the shaft guide portion (421). The second guide protrusion (W2) rotates along the second guide curved surface (428, A42). The second guide protrusion (W2) is guided from the front end to the rear end of the second guide curved surface (428, A42).

[0157] Accordingly, the rotating plate (440) is rotated around the shear rotation point (O) of the shaft guide part (421).

[0158] Referring to FIG. 10d, as the rotation plate (440) continues to rotate, the rotation plate (440) moves backward and rotates.

[0159] The second guide projection (W2) is moved rearward along the second guide inclined surface (426, A3), and the second guide projection (W2) becomes adjacent to the rear end of the second guide curved surface (428, A42). The rotation axis (430, R) is moved from the front end of the axis guide portion (421) to the middle of the axis guide portion (421). The first guide projection (W1) is located in front of the connecting surface (423).

[0160] Referring to FIG. 10e, as the rotating plate (440) continues to rotate, the rotating plate (440) moves backward and rotates.

[0161] The second guide projection (W2) is spaced apart from the rear of the second guide inclined surface (426, A3). The rotation axis (430, R) is located at the rear end of the shaft guide portion (421). The first guide projection (W1) is located at the opening (422) of the shaft guide portion (421).

[0162] That is, the positions of the first guide projection (W1) and the second guide projection (W2) are swapped with those of FIG. 10a. Since the rotating plate (440) is rotated 180 degrees, the user can easily take out the stored item at the rear end of the rotating plate (440).

[0163] In conclusion, the rotating plate (440) moves forward while rotating 90 degrees and moves backward while rotating from 90 degrees to 180 degrees.

[0164]

[0165] Below, other rotary lathes in other embodiments are described in detail.

[0166] 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.

[0167] The embodiment of FIG. 11 differs from the embodiments of FIG. 1 to FIG. 10 (first embodiment) in that the rotating shelf (400') is coupled to the shelf of the refrigerator.

[0168] The rotating shelf (400') may be seated or installed on the shelf (9). The rotating shelf (400') may also be detachable from the shelf (9). The rotating shelf (400') may be attached or connected to the upper surface of the shelf (9) by means of an adsorption member (490) or a coupling member.

[0169] The suction member (490) can be attached to the bottom of the shelf base (410). It is preferable that 2 to 4 suction members (490) be placed on the shelf base (410). The suction member (490) is suctioned to the upper surface of the shelf (9) of the refrigerator.

[0170] The shelf base (410) 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 (410) may have a smaller size than the shelf (9) of the refrigerator so that the rotating shelf (400') can be easily detached from the shelf (9) of the refrigerator.

[0171] In the shelf base (410) of the second embodiment, the bracket joint (415) is omitted compared to the first embodiment.
