Description

Rotating lathes and 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 capable of easily taking out stored items stored at the rear of the shelf and utilizing 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 refrigerator-only rotating auxiliary shelf is disclosed that supports the load of food, side dishes, food ingredients, or at least one container for storing or containing the food, side dishes, or food ingredients and rotates the first circular upper panel by 1 to 360 degrees, thereby enabling food, side dishes, or food ingredients stored deep inside a refrigerator, which are essential items among home appliances, to be taken out and used immediately.

[0005] However, in the case of patent document 1, since the first circular upper panel is circular, there is a problem that the space for storing food is narrow, and generally, the entire square space of the shelf in the refrigerator cannot be utilized, and since the first circular upper panel only rotates in place, there is a problem that even when the first circular upper panel is rotated, it is difficult for the user to take it out at a distance.

[0006] 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.

[0018] The above rack gear can be formed in the moving space.

[0019] The above rotating plate further includes an axis member rotatably coupled to the shelf base, and the axis gear can be arranged to surround the axis member.

[0020] The shelf base may further include an axis guide that guides the axis member to be inserted and moved in the first direction.

[0021] The shelf base further includes a moving space that provides a space in which the shaft gear is accommodated and moved, the shaft guide may be formed on one side of the moving space, and the rack gear may be formed on the other side intersecting the one side of the moving space.

[0022] The above-mentioned axis guide may be formed by penetrating the shelf base and may be a long hole extending in the first direction.

[0023] Additionally, the present disclosure may further include an axis holder that limits the axis member from being dislodged from the axis guide.

[0024] The above rotating plate includes a support plate that supports a storage material on the upper surface, and the shaft gear can be installed on the lower surface of the support plate.

[0025] The above-mentioned shaft gear has an axis extending in a direction intersecting the support plate, and the axis of the above-mentioned shaft gear can be aligned with the center of the above-mentioned rotating plate.

[0026] The shelf base may include a base plate, a moving space having a height lower than the base plate and providing a space in which the shaft gear is accommodated and moved, and an axis guide formed in the moving space and guiding the shaft member to be inserted and moved in the first direction.

[0027] According to one embodiment of the present disclosure, a home appliance 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 rotatably installed on the shelf base, a rack gear installed on the shelf base and extending in a first direction, and an axial gear installed on the rotating plate and meshed with the rack gear, wherein the axial gear is rotated by rotation of the rotating plate, and the axial gear and the rotating plate move along the rack gear.

[0028]

[0029] The above-mentioned axis guide may be formed on the bottom surface of the moving space, and the above-mentioned rack gear may be formed on the side surface of the moving space.

[0063] Below, the explanation is based on a refrigerator, which is an example of a home appliance, but is not limited to this.

[0064]

[0065] Before explaining, let's define the direction. In the embodiment of the present disclosure, the direction in which the front of the door as shown in FIG. 1 faces is defined as front, the direction toward the cabinet based on the front of the door is defined as rear, the direction toward the floor surface on which the refrigerator is installed is defined as downward, and the direction away from the floor surface is defined as upward.

[0066] FIG. 1 is a perspective view of a refrigerator (1) according to one embodiment of the present disclosure, FIG. 2a is a perspective view of the interior of a storage space of the refrigerator illustrated in FIG. 1, and FIG. 2b is a drawing illustrating a rotating shelf arranged in the storage space illustrated in FIG. 2a in a rotated state.

[0067] 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) forming a storage space (12, 13) and a door (20) for opening and closing the storage space (12, 13).

[0068] The storage space (12, 13) inside the cabinet (10) can be partitioned vertically by partition walls (not shown), and a refrigerator (12) can be formed in the upper part of the cabinet (10) and a freezer (13) can be formed in the lower part of the cabinet (10).

[0069] The storage space (12, 13) can be partitioned vertically by shelves (9). Specifically, the refrigerator (12) can be partitioned vertically by shelves (9). The shelves (9) extend in a direction parallel to the front-back direction.

[0070] For example, the cabinet (10) may include a rear surface (123) facing the door (20), and a side surface (122) extending from the edge of the rear surface (123) and defining a surface intersecting the rear surface (123). The side surface (122) may extend in the front-back direction.

[0071] Additionally, 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).

[0072] And, an output unit (not shown) is connected to the control unit to output the operating status of the refrigerator (1). The output unit may include a display that displays information on a screen or a speaker that displays information in voice. And, an operation unit (not shown) is connected to the control unit to input operations for the operation of the refrigerator (1). In addition to physical input methods such as buttons, switches, and touch, the operation unit may include a microphone capable of inputting voice.

[0073] In the embodiment of the present disclosure, the control unit (15) is described as being placed on the upper surface of the cabinet (10), but the control unit (15) may be provided at various locations of the refrigerator (1), and may be configured in multiple units and placed at different locations.

[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 rotating, and the freezer door (22) may be configured to open and close the open front of the freezer (13) by rotating. Meanwhile, the refrigerator door (21) may be referred to as an upper door (20) because it is provided at the top, and the freezer door (22) may be referred to as a lower door (20) because it is provided at the bottom.

[0075] And, the refrigerator door (21) may be configured to be provided with a left and right pair so that the refrigerator (12) is shielded by the pair of doors (21, 22). And, the freezer door (22) may be provided with a left and right pair 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 drawer-type and withdrawable as needed, and may be configured with one or more doors.

[0076] In the embodiment of the present disclosure, a refrigerator (1) having a bottom freeze type refrigerator (1) with a freezer (13) provided at the bottom and a French type door (20) that rotates to open and close a single space is described as an example, 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 configured with a main door (40) and a sub-door (30). The main door (40) may be rotatably mounted on the cabinet (10) to open and close the refrigerator (12). In addition, an opening (41 in FIG. 2) may be formed through the main door (40).

[0078] The sub-door (30) is provided in front of the main door (40) and can be rotatably mounted on the main door (40). In addition, the sub-door (30) can open and close the opening (41). In addition, the sub-door (30) can be formed with a transparent portion (31) that can view the inside of the opening (41). The transparent portion (31) can be composed of at least one transparent panel and can be selectively configured so that the inside of the opening (41) is visible. In addition, if necessary, the transparent portion (31) can be composed of a display device such as an LCD capable of screen output or a transparent LCD.

[0079] FIG. 3 is a perspective view of a rotary lathe (400) arranged in the storage space illustrated in FIG. 2a, FIG. 4 is an exploded perspective view of the rotary lathe (400) illustrated in FIG. 3, FIG. 5 is an exploded perspective view of the rotary lathe (400) viewed from a different direction from FIG. 4, and FIG. 6 is a cross-sectional view taken along line 6-6' of the rotary lathe (400) illustrated in FIG. 4.

[0080] Referring to FIGS. 3 to 6, the rotating lathe (400) may be mounted or installed on the lathe (9). The rotating lathe (400) may also be detachable from the lathe (9).

[0081] A rotary lathe (400) according to one embodiment of the present disclosure includes a lathe base (440) and a rotary plate (410).

[0082] A rotary lathe (400) according to one embodiment of the present disclosure has a rotary plate (410) that can rotate and translate on a lathe base (440). The rotary plate (410) can rotate and translate with respect to the lathe base (440) by the relative motion of the shaft gear (418) of the rotary plate (410) and the rack gear (445) of the rotary lathe (400).

[0083] The shelf base (440) is stationary and can be attached to or detached from a shelf of a home appliance. For example, a detachable member (490) that can be attached or detached to a shelf (9) may be installed on the shelf base (440). A detachable connecting portion (491) to which the detachable member (490) is attached may be formed on the shelf base (440).

[0084] The detachable member (490) may be an adsorption member that is attached to the lower surface of the shelf base (440) and is adsorbed to the shelf (9).

[0085] The detachable joint (491) may be a groove formed on the lower surface of the shelf base (440) into which the detachable member (490) is inserted. The detachable joint (491) may be arranged symmetrically on both sides of the shelf base (440) with respect to the axis guide (446).

[0086] The shelf base (440) supports the rotating plate (410) to rotate and translate, and may not interfere when the rotating plate (410) rotates.

[0087] For example, the shelf base (440) may include a plate-shaped base plate (441), a moving space (444), an axis guide (446), and a rack gear (445).

[0088] The moving space (444) has a lower height than the base plate (441), thereby providing a space in which the shaft gear (418) is accommodated and in which the shaft gear (418) moves. Specifically, the moving space (444) may have a groove shape in which the upper surface of the base plate (441) is sunken downward.

[0089] The moving space (444) may include a space bottom surface (4441) having a step with a base plate (441), and a space side surface (4442) connecting both ends of the space bottom surface (4441) and the base plate (441) and extending in a direction intersecting the space bottom surface (4441).

[0090] The moving space (444) extends forward and backward from the base plate (441). The moving space (444) may be located at the center of the base plate (441).

[0091] The shaft guide (446) guides the shaft member (417) of the rotation plate (410) to be inserted and to move and rotate in the first direction (forward). Specifically, the shaft guide (446) may be a hole formed by penetrating the shelf base (440) plate. The shaft guide (446) may be a long hole extending in the front-back direction.

[0092] More specifically, the axis guide (446) can be formed in the moving space (444). The axis guide (446) can be formed on one surface of the moving space (444). The axis guide (446) can be formed on the space bottom surface (4441). The axis guide (446) can be formed by penetrating the space bottom surface (4441).

[0093] The rack gear (445) meshes with the shaft gear (418) of the rotating plate (410) to allow the shaft gear (418) to move while rotating. The rack gear (445) is gear-coupled with the shaft gear (418) of the rotating plate (410) to allow the shaft gear (418) to move while rotating. Here, gear coupling and meshing are structures in which the teeth (teeth) of the shaft gear (418) and the teeth (teeth) of the rack gear (445) mesh with each other to transmit force or rotational force.

[0094] The rack gear (445) can extend in the first direction. Specifically, the rack gear (445) is formed to be long in the front and rear directions.

[0095] The rack gear (445) can be formed in the moving space (444). When the rack gear (445) is formed in the moving space (444), the shaft gear (418) is accommodated in the moving space (444), which has the advantage of reducing the thickness of the rotating lathe (400).

[0096] Specifically, the rack gear (445) can be formed on a space side surface (4442) that is different from the space bottom surface (4441) on which the shaft guide (446) is formed. When the rack gear (445) is formed on the space side surface (4442), the shaft gear (418) forms a rotation axis in a direction parallel to the vertical direction, and the rotation plate (410) can move in the forward and backward direction by the rotation of the shaft gear (418).

[0097] The rack gear (445) can be arranged parallel to the shaft guide (446). When the rack gear (445) and the shaft guide (446) are parallel, when the shaft gear (418) moves while rotating around the rack gear (445), the distance between the shaft gear (418) and the rack gear (445) can be maintained constant.

[0098]

[0099] The rotating plate (410) is positioned on the shelf base (440) and rotates and translates with respect to the shelf base (440). Therefore, as the rotating plate (410) moves forward, it rotates 90 degrees or 180 degrees, so that the stored material positioned at the rear end of the rotating plate (410) can be easily taken out.

[0100] The rotating plate (410) may include a support plate (411), an axis member (417), and an axis gear (418).

[0101] The support plate (411) supports the stored material. The support plate (411) may be plate-shaped. The front and rear surfaces of the support plate (411) extend in a direction perpendicular to the front and rear direction, and the left and right surfaces of the support plate (411) may be rounded. If the support plate (411) is rectangular, when the support plate (411) rotates, the corners of the rectangle may interfere with other surfaces of the storage or the shelf base (440), making rotation difficult. If the length is reduced to reduce this interference, the area of ​​the support plate (411) is greatly reduced. To overcome this drawback, if the left and right surfaces of the support plate (411) form curves, the support plate (411) can rotate while having a larger area than when it is rectangular.

[0102] The rotating plate (410) may further include an edge wall (412). The edge wall (412) restricts movement of the stored material. The edge wall (412) may protrude upward from the edge of the support plate (411). The edge wall (412) may be formed only on the left and right ends of the support plate (411).

[0103] The rotating plate (410) may further include a lever protrusion (419). The lever protrusion (419) may protrude downward from the edge of the support plate (411). Specifically, the lever protrusion (419) may be formed only at the front and rear ends of the support plate (411) where the edge wall (412) is not formed. The lever protrusion (419) provides a gripping force when a user rotates the rotating plate (410).

[0104] The shaft member (417) is coupled to the shelf base (440) and defines the rotation axis of the rotating plate (410). The shaft member (417) can be directly inserted into the shaft guide (446) of the shelf base (440).

[0105] The shaft member (417) may be formed by protruding from the support plate (411). Specifically, the shaft member (417) becomes the center of rotation of the rotating plate (410). The shaft member (417) may be placed at the center of the shaft gear (418).

[0106] The shaft gear (418) is engaged with the rack gear (445) and rotates to move along the rack gear (445). The shaft gear (418) may have a ring shape surrounding an arbitrary center point. The shaft gear (418) may have a ring shape surrounding a shaft member (417). In addition, the shaft gear (418) may have a cylindrical shape, and the shaft member (417) may be formed by protruding from the center of the shaft gear (418). Teeth are formed on the circumference surrounding an arbitrary center point of the shaft gear (418).

[0107] The shaft gear (418) may be formed to protrude from the lower surface of the support plate (411). The shaft gear (418) may have an axis extending in a direction intersecting with the support plate (411) of the rotating plate (410). Specifically, the shaft gear (418) has an axis that is parallel to the vertical direction. The center (or axis) of the shaft gear (418) may coincide with the center of the rotating plate (410).

[0108] The diameter of the shaft gear (418) may be smaller than the width of the moving space (444). If the diameter of the shaft gear (418) is smaller than the width of the moving space (444), the shaft gear (418) can be accommodated in the moving space (444) to reduce the thickness of the rotating lathe (400).

[0109] When the rotating plate (410) rotates, the shaft gear (418) also rotates, and when the shaft gear (418) rotates, the shaft gear (418) moves along the rack gear (445), and the rotating plate (410) moves along the direction of the rack gear (445). At this time, the shaft member (417) is guided by the shaft guide (446), thereby maintaining a constant distance between the shaft gear (418) and the rack gear (445), and preventing the rotating plate (410) from being separated from the shelf base (440).

[0110] When the rotation plate (410) is rotated in the forward direction, the rotation plate (410) can be moved forward, and when the rotation plate (410) is rotated in the reverse direction, the rotation plate (410) can be moved backward.

[0111] The shaft gear (418) may have a gear number positioned at the front end of the moving space (444) when the shaft gear (418) rotates 180 degrees. Accordingly, even if the user rotates the rotating plate (410), the rotating plate (410) is not rotated more than 180 degrees due to the gear number and is positioned in the fixed position. Of course, the shaft gear (418) may have a gear number positioned at the front end of the moving space (444) when the shaft gear (418) rotates 90 degrees.

[0112]

[0113] Meanwhile, the shaft member (417) is inserted into the shaft guide (446) of the shelf base (440), and a shaft holder (480) can be coupled to the end of the shaft member (417). The shaft holder (460) restricts the shaft member (417) from being separated from the shaft guide (446). The shaft holder (460) can have a width greater than the width of the shaft guide (446). The shaft holder (460) is located at the bottom of the shaft guide (446).

[0114] A holder receiving portion (447) for receiving a shaft holder (460) may be formed on the shelf base (440). The holder receiving portion (447) may be formed by the lower surface of the shelf base (440) being sunken upward. Since the shaft holder (460) is coupled to the shaft member (417) and rotates together with the shaft member (417), if the shaft holder (460) comes into contact with the floor, the rotation of the rotating plate is restricted, and therefore, a structure for separating the shaft holder (460) from the floor is required.

[0115] The present disclosure may further include an anti-friction unit that prevents friction between the shelf base (440) and the rotating plate (410).

[0116] The anti-friction unit (420) is positioned between the shelf base (440) and the rotating plate (410) to limit contact between the shelf base (440) and the rotating plate (410). The anti-friction unit (420) can reduce or eliminate friction between the shelf base (440) and the rotating plate (410).

[0117] The planar area of ​​the shelf base (440) and the rotating plate (410) may be larger than the planar area of ​​the anti-friction unit (420). Therefore, the planar area of ​​the anti-friction unit (420) is smaller than that of the shelf base (440) and the rotating plate (410), thereby reducing the contact area between the shelf base (440) and the rotating plate (410). Here, the planar area of ​​each component refers to the area of ​​each component when viewed from above.

[0118] Referring to FIGS. 4 and 7, the anti-friction unit may include a bearing (421) installed on either the shelf base (440) or the rotating plate (410). Hereinafter, the description will be made based on the bearing (421) being installed on the shelf base (440), but the present invention is not limited thereto.

[0119] A plurality of bearings (421) may be arranged symmetrically around the rotation axis of the rotating plate (410). The plurality of bearings (421) may be arranged spaced apart from each other on a circular orbit based on the center of the shelf base (440).

[0120] The shelf base (440) may further include a slider receiving portion (443) that receives a bearing (421). The slider receiving portion (443) may be formed by the upper surface of the base plate (441) being sunken downward. The slider receiving portion (443) may receive the lower portion of the bearing (421).

[0121] In addition, the present disclosure may further include a slider cover (422) that prevents the bearing (421) from being detached from the shelf base (440). The shelf base (440) may further include a cover receiving portion (442) in which the slider cover (422) is received. The cover receiving portion (442) is formed by recessing the upper surface of the base plate (441) downward. The cover receiving portion (442) may be arranged to surround the slider receiving portion (443).

[0122] The slider cover (422) has a structure that surrounds a portion of the upper part of the bearing (421) and exposes the top of the bearing (421).

[0123] The rotating plate (410) stably supports the storage material by a plurality of bearings (421) and can rotate smoothly.

[0124]

[0125] Below, the operation of the rotary lathe (400) is described.

[0126] FIGS. 8A to 8C are drawings illustrating a rotary lathe (400) in operation according to one embodiment of the present disclosure.

[0127] Referring to FIG. 8 a, in the storage state, when the user holds the edge of the rotating plate (410) and pulls the left or right end of the rotating plate (410), the rotating plate (410) rotates in the forward direction.

[0128] Referring to FIG. 8B, when the rotating plate (410) rotates, the shaft gear (418) that is constrained to rotate by the rotation of the rotating plate (410) rotates. When the shaft gear (418) rotates, the shaft gear (418) moves forward along the rack gear (445). When the shaft gear (418) moves forward, the rotating plate (410) also moves forward. The rotating plate (410) and the shaft gear (418) rotate around the shaft member (417), and the shaft member (417) is guided along the shaft guide (446).

[0129]

[0130] Referring to Fig. 8c, when the rotating plate (410) is rotated 180 degrees from the initial position, the shaft gear (418) comes into contact with the front end of the moving space (444), and the shaft member (417) comes into contact with the front end of the shaft guide (446). Therefore, when the rotating plate (410) is rotated 180 degrees from the initial position, the forward rotation and forward movement of the rotating plate (410) are restricted.

[0131]

[0132] Users can easily retrieve the storage located at the rear.

[0133] When the rotating plate (410) is rotated in the reverse direction, the rotating plate (410) moves backward while rotating in the reverse direction.

[0134]

[0135] FIGS. 9a to 9c are drawings illustrating a rotary lathe (400') in operation according to another embodiment of the present disclosure.

[0136] In another embodiment, another rotary lathe is structured so that the rotary plate (410) moves forward and rotates 90 degrees or 180 degrees.

[0137] The shaft gear (418) may have a gear number positioned at the front end of the moving space (444) when the shaft gear (418) rotates 180 degrees. Therefore, even if the user rotates the rotation plate (410), the rotation plate (410) is not rotated more than 180 degrees due to the gear number and is positioned in the correct position.

[0138] Referring to FIG. 9 a, in the stored state, when the user holds the edge of the rotating plate (410) and pulls the left or right end of the rotating plate (410), the rotating plate (410) rotates in the forward direction.

[0139] Referring to FIG. 9B, when the rotating plate (410) rotates, the shaft gear (418) that is constrained to rotate by the rotation of the rotating plate (410) rotates. When the shaft gear (418) rotates, the shaft gear (418) moves forward along the rack gear (445). When the shaft gear (418) moves forward, the rotating plate (410) also moves forward. The rotating plate (410) and the shaft gear (418) rotate around the shaft member (417), and the shaft member (417) is guided along the shaft guide (446).

[0140] Referring to Fig. 9c, when the rotation plate (410) is rotated 180 degrees from the initial position due to the gear number of the shaft gear (418), the shaft gear (418) comes into contact with the front end of the moving space (444), and the shaft member (417) comes into contact with the front end of the shaft guide (446). Therefore, when the rotation plate (410) is rotated 180 degrees from the initial position, the forward rotation and forward movement of the rotation plate (410) are restricted.

[0141] Therefore, the user can easily take out the storage located at the rear.

[0142] When the rotating plate (410) is rotated in the reverse direction, the rotating plate (410) moves backward while rotating in the reverse direction.
