Description

Technical Field

[0001] The present invention relates to a door position adjustment mechanism and a refrigerator provided with the same.

Background Art

[0002] As a conventional refrigerator, there is a built-in refrigerator configured by attaching a design surface to a heat insulating door, and in recent years, a type of refrigerator that allows the design surface of the heat insulating door itself to be replaced has appeared. By making the design surface replaceable in this way, users are enabled to freely customize the refrigerator, for example, to create a sense of unity in color, design, and the like with adjacent cabinets.

[0003] However, dimensional variations of the door and the cabinet may occur during the foaming of the heat insulating material in the refrigerator manufacturing process, which may cause a slight misalignment of the heat insulating door. Although such misalignment can be covered by the design surface in the manufacturing process, in the case of a refrigerator of the type with a replaceable design surface, the misalignment of the heat insulating door becomes noticeable at the time of replacement, leading to user dissatisfaction. As another problem, the door may sag under the weight of stored items accommodated in the door, which may cause, for example, the design surface of the door to appear inclined or the misalignment with adjacent cabinets to be prominent, potentially impairing the design appearance.

[0004] Accordingly, in order to ensure the design appearance, a mechanism that allows the door position to be adjusted after delivery is required. As such a door position adjustment mechanism, as shown in Patent Document 1, there is a mechanism configured to adjust the vertical position of the door by allowing one or more plates to be inserted into and removed from between the door and the hinge.

[0005] However, with such a configuration, the vertical position adjustment of the door is stepwise, and fine adjustment of the door in the vertical direction cannot be performed, as a result, the design appearance cannot necessarily be ensured.

[0006] [Patent Document 1] U.S. Publication No. 8,511,768 [Overview of the project] [Problems that the invention aims to solve]

[0007] Therefore, the present invention was made to solve the above-mentioned problems, and its main objective is to enable stepless adjustment of the door position, at least in the vertical direction. [Means for solving the problem]

[0008] In other words, the door position adjustment mechanism according to the present invention is a door position adjustment mechanism interposed between a door and a hinge that rotatably supports the door to adjust the position of the door, and is characterized by having a screw member for adjusting the position of the door in the vertical direction.

[0009] With this door position adjustment mechanism, the door's position is adjusted vertically using a screw member, allowing for stepless vertical adjustment. For example, when applied to a built-in refrigerator, it eliminates door tilt and misalignment with adjacent cabinets, thus ensuring aesthetic appeal.

[0010] Preferably, the device comprises a door base fixed to the door and a hinge base fixed to the hinge, with the screw member interposed between the door base and the hinge base so as to be able to move back and forth between them. With this configuration, a door position adjustment mechanism can be installed without modifying the design of existing hinges, and the door can be adjusted while maintaining the strength of the hinges.

[0011] By the way, if the above-mentioned door position adjustment mechanism is provided on both the upper and lower sides of the door, and the screw members are configured to be screwed into the hinge base, then even if you try to adjust the door's position vertically using the upper screw member, for example, the door cannot be moved up or down because the lower screw member is screwed into the hinge base. Therefore, it is preferable that the door base and the hinge base face each other in the vertical direction, and that an adjuster block is further provided, which is interposed between the door base and the hinge base and into which the screw member is screwed. With this configuration, since the screw member is screwed into the adjuster block, the adjuster block is free to move up and down relative to the hinge base. For example, if the door is moved up and down using the upper screw member, the lower screw member will move along with the adjuster block, allowing the door to be positioned vertically.

[0012] It is preferable that the door be adjustable in the left-right direction as well. This allows for even alignment of the gaps between adjacent cabinets, ensuring a harmonious design when combined with the surrounding cabinets.

[0013] It is preferable that the door be adjustable in the front-to-back direction as well. This allows for alignment of the design plane with adjacent cabinets, for example, when applied to a built-in refrigerator.

[0014] When the door is closed, it is preferable that at least a portion of the components are positioned to the side of the hinge. This prevents the door position adjustment mechanism from interfering with the gasket and gasket groove located in front of the hinge. This is particularly effective when the gap between the hinge and the door is small, and there is almost no space at the bottom.

[0015] Furthermore, the refrigerator according to the present invention is characterized by being equipped with the door position adjustment mechanism described above. Such a refrigerator can provide the same effects as the aforementioned door position adjustment mechanism, even when multiple refrigerators are arranged side by side or placed in a storage space. Specifically, it can eliminate door tilting and height differences between adjacent cabinets, thereby ensuring aesthetic appeal.

[0016] It is preferable that the door position adjustment mechanism is provided on both the upper and lower sides of the door. With this configuration, the door's load can be supported by door position adjustment mechanisms at both the top and bottom of the door, and furthermore, finer adjustments to the door's position become possible.

[0017] An embodiment in which the effects and advantages of the present invention are more clearly demonstrated is a refrigerator in which the design surface facing forward of the door is configured to be replaceable.

[0018] Incidentally, while typical refrigerators use single-axis hinges, using single-axis hinges in a built-in refrigerator would necessitate positioning the refrigerator door slightly forward of the adjacent cabinet to ensure a sufficient door opening angle and avoid interference. This would make it impossible to align the design planes with adjacent cabinets, compromising the aesthetic appeal. Therefore, it is preferable that the hinge is a multi-axis hinge that rotates the door while pushing it forward. With this configuration, it is possible to achieve a wide door opening angle while aligning the design surfaces, thus ensuring aesthetic appeal. On the other hand, unlike single-axis hinges, multi-axis hinges have multiple link members and multiple rotation axes, so refrigerators using multi-axis hinges are more prone to door sagging than refrigerators using single-axis hinges. For this reason, the effects of the door position adjustment mechanism of the present invention are more pronounced in refrigerators using multi-axis hinges. [Effects of the Invention]

[0019] According to the present invention configured as described above, the door position can be adjusted steplessly at least in the vertical direction. For example, when applied to a built-in type refrigerator, it is possible to eliminate the inclination of the door and the level difference with the adjacent cabinet, thereby ensuring the design quality.

[Figure 10] A schematic diagram showing the disassembled state of the door position adjustment mechanism in another embodiment. [Modes for Carrying Out the Invention]

[0021] Hereinafter, one embodiment of the refrigerator according to the present invention will be described with reference to the drawings.

[0022] As shown in Figure 1, the refrigerator R according to this embodiment is a so-called built-in type and comprises one or more cabinets C, a single-opening or double-opening door D provided on the cabinet C, and a hinge H that rotatably supports the door D.

[0023] As shown in Figure 2, the hinge H has a fixed arm H1 attached to the cabinet C and a movable arm H2 attached to the door D and movable relative to the fixed arm H1. In this case, it is a multi-axis hinge that rotates the door D while pushing it forward.

[0024] By using such a multi-axis hinge H, the design surface D1 facing forward of the door D can be positioned on the same plane as the wall surface of a kitchen or, if another cabinet is adjacent, the design surface facing forward of that cabinet. In other words, the refrigerator R of this embodiment can be positioned so that the front-to-back position of the design surface D1 of the door D is aligned with the front-to-back position of the design surface of the wall or adjacent cabinet.

[0025] Furthermore, the refrigerator R of this embodiment is configured so that the decorative surface D1 of the door D can be replaced. Specifically, a detachable mechanism (not shown) is provided between the main body portion D2 of the door D and the decorative surface D1, allowing the user to attach a decorative surface D1 of a desired color or design to the main body portion D2 of the door D. In this embodiment, the decorative surface D1 of the door D has the same dimensions as the front surface of the main body portion D2, and if misalignment occurs, such as door sagging caused by the use of a multi-axis hinge H, the decorative surface D1 cannot cover up that misalignment. Thus, when the decorative surface D1 and the main body portion D2 have the same dimensions, the misalignment of the door D is noticeable not only when replacing the decorative surface D1, but also when the decorative surface D1 is attached.

[0026] Therefore, rather than concealing the aforementioned misalignment, the refrigerator R of this embodiment is equipped with a door position adjustment mechanism 100, as shown in Figure 3, which is interposed between the hinge H and the door D and is capable of steplessly adjusting the position of the door D at least in the vertical direction.

[0027] In this embodiment, door position adjustment mechanisms 100 are provided on both the upper and lower sides of door D. Since these door position adjustment mechanisms 100 have a vertically symmetrical structure, the following description will focus on the door position adjustment mechanism 100 provided on the upper side of the right-handed door D, as a representative example.

[0028] Some of the components that make up the door position adjustment mechanism 100 are located on the central side of the door D, or in other words, to the side of the hinge H when the door D is closed, as shown in Figures 3 and 4. Specifically, these components include a screw member 10 (hereinafter also referred to as the vertical adjustment screw 10), a door base 20 fixed to the door D, and a hinge base 30 fixed to the hinge H.

[0029] The vertical adjustment screw 10 is interposed between the door base 20 and the hinge base 30, and is attached to either the door base 20 or the hinge base 30, and is movable back and forth relative to the other. Specifically, various types of screws, such as bolts and screws, can be used as long as they have threads formed on their outer surface.

[0030] The vertical adjustment screw 10 here, as shown in Figures 3 and 4, is attached to the door base 20 and moves back and forth relative to the hinge base 30. Here, the head has a constricted shape, and this constricted portion 11 is hooked onto the notch 22x of the door base 20, which will be described later, thereby attaching it to the door base 20.

[0031] As shown in Figures 3 and 4, the door base 20 is plate-shaped and has a door-side mounting portion 21 that is attached to the door D, and a screw mounting portion 22 to which the above-mentioned vertical adjustment screw 10 is attached.

[0032] The door-side mounting portion 21 is a flat plate extending in the width direction of the door D, and is fixed to the surface of the door D facing the interior side using, for example, a screw member B0 such as a bolt.

[0033] The screw mounting portion 22 is a flat plate that is bent inward from the mounting portion, and is provided with a notch 22x for mounting the upper and lower adjustment screws 10 described above. The shape of the notch 22x is not particularly limited, but in this case it is U-shaped and opens toward the inside of the oven.

[0034] As shown in Figures 3 and 4, the hinge base 30 is plate-shaped and has a hinge-side mounting portion 31 that is attached to the movable arm H2 which constitutes the hinge H, and a pressure-receiving portion 32 that receives the pressing force from the upper and lower adjustment screw 10 mentioned above.

[0035] The hinge-side mounting portion 31 is a flat plate extending in the width direction of the door D, and is interposed between the hinge H and the door D, more specifically between the lower surface of the hinge H and the upper surface of the door D, and is fixed to the lower surface of the hinge H using, for example, a bolt or other screw member or a rivet.

[0036] The pressure-receiving portion 32 is a flat plate that extends from the hinge-side mounting portion 31 toward the center of the door D, and is positioned opposite the screw mounting portion 22 described above.

[0037] Here, as shown in Figures 3 and 4, the door position adjustment mechanism 100 of this embodiment further includes an adjuster block 40 interposed between the screw mounting portion 22 and the pressure receiving portion 32 described above, and having a screw hole 40h into which the vertical adjustment screw 10 is screwed.

[0038] In this configuration, when the vertical adjustment screw 10 is loosened relative to the adjuster block 40, the vertical adjustment screw 10 lifts the door base 20, causing the door D to which the door base 20 is fixed to lift. On the other hand, when the vertical adjustment screw 10 is tightened relative to the adjuster block 40, the door base 20 lowers along with the vertical adjustment screw 10, causing the door D to lower.

[0039] In this way, by moving the vertical adjustment screw 10 back and forth in the vertical direction, the door D can be moved vertically relative to the movable arm H2 of the hinge H, that is, relative to the cabinet C.

[0040] On the other hand, if door D is not to be moved vertically, the door base 20 needs to be fixed in the vertical direction, and here the door base 20 can be fixed to the hinge base 30.

[0041] More specifically, as shown in Figure 4, the door base 20, adjuster block 40, and hinge base 30 have overlapping through holes h1 to h3, and the door base 20 is fixed to the hinge base 30 using screw members B1 such as screws passed through these through holes h1 to h3. The door base 20 has a pair of through holes h1 on both the left and right sides of the aforementioned notch 22x, and the adjuster block 40 and hinge base 30 have a pair of through holes h2 and h3 at locations corresponding to these through holes h1.

[0042] By the way, as mentioned above, the door position adjustment mechanism 100 is provided on both the upper and lower sides of the door D. Therefore, even if you try to adjust the position of the door D vertically using the upper vertical adjustment screw 10, for example, the lower vertical adjustment screw 10 is screwed into the screw hole 40h of the adjuster block 40, so you cannot move the door D up or down.

[0043] Therefore, when adjusting the vertical position of door D, it is first necessary to loosen the screw members B1 that pass through the aforementioned through holes h1 to h3 in the upper and lower door position adjustment mechanisms 100 of door D.

[0044] As a result, the upper and lower adjuster blocks 40 become free in the vertical direction. Therefore, as shown in Figures 5(a) and (b), if the door D is moved vertically using the upper vertical adjustment screw 10, the lower vertical adjustment screw 10 moves along with the adjuster block 40, allowing the door D to be positioned vertically.

[0045] Then, as shown in Figures 5(b) and (c), the lower adjuster block 40 is pressed against the hinge base 30 using the lower vertical adjustment screw 10, and in this state, the vertical adjustment of the door position is completed by tightening the screw members B1 into the through holes h1 to h3 in the upper and lower door position adjustment mechanisms 100.

[0046] Here, the door position adjustment mechanism 100 of this embodiment is configured to allow stepless position adjustment not only in the vertical direction of the door D, but also in the front-to-back and left-to-right directions, which will be explained below.

[0047] First, regarding the adjustment of the position in the front-to-back direction, as described above, the door base 20 of this embodiment has a through hole h1 formed therein for passing a screw member B1 (hereinafter also referred to as the front-to-back adjustment fixing screw B1), as shown in Figure 4, and this through hole h1 is an elongated hole that extends in the front-to-back direction.

[0048] This allows the door base 20 to be moved and fixed relative to the hinge base 30 by the length of the elongated hole h1 in the front-to-back direction, and the door D can be moved in the front-to-back direction as the door base 20 moves.

[0049] Next, regarding movement in the left-right direction, as shown in Figure 4, the door position adjustment mechanism 100 of this embodiment further includes a slide plate 50 interposed between the door base 20 and the hinge base 30.

[0050] This slide plate 50 is flat and is sandwiched between the adjuster block 40 and the hinge base 30. In this embodiment, the slide plate 50 is attached to the door base 20 and the adjuster block 40, and is integrally attached to the hinge base 30, and has a through hole h4 into which the aforementioned front-to-back adjustment fixing screw B1 is inserted.

[0051] Furthermore, the slide plate 50 has an elongated hole h5 that extends in the left-right direction, separate from the through hole h4 described above, through which a screw member B2 such as a bolt (hereinafter also referred to as the left-right adjustment fixing screw B2) passes. The hinge base 30 has a through hole h6 formed at a location corresponding to this elongated hole h5 through which the left-right adjustment fixing screw B2 passes. In this case, a pair of elongated holes h5 are formed on the left and right outer sides of the through hole h4 described above.

[0052] This allows the slide plate 50 to be moved and fixed relative to the hinge base 30 by the length of the elongated hole h5 in the left-right direction, and as the slide plate 50 moves, the adjuster block 40, door base 20, and door D can be moved together in the left-right direction.

[0053] With a refrigerator R configured in this way, the door D can be adjusted vertically using the vertical adjustment screw 10, allowing for stepless vertical adjustment of the door D. For example, if applied to a built-in type refrigerator R, it can eliminate the tilt of the door D and any gaps between it and adjacent cabinets, thus ensuring aesthetic appeal.

[0054] Furthermore, since the door position adjustment mechanism 100 of this embodiment can move the door D in the front-to-back direction and the left-to-right direction, the design surface position can be aligned with adjacent cabinets by adjusting the position in the front-to-back direction, and the left-to-right position can be aligned to evenly match the left-to-right gaps with adjacent cabinets by adjusting the position in the left-to-right direction.

[0055] The door position adjustment mechanism 100 of this embodiment is provided in a space hidden by the design surface D1 on the inside of the upper or lower part of the door D, and since the adjustment mechanism in three directions—up and down, left and right, and front and back—is housed in a limited space, the aesthetic appeal can be ensured in this sense as well.

[0056] Furthermore, since the door position adjustment mechanism 100 is assembled using a door base 20 fixed to door D and a hinge base 30 fixed to hinge H, the door position adjustment mechanism 100 can be installed without redesigning the existing hinge H, and the door D can be adjusted while maintaining the strength of hinge H.

[0057] Furthermore, since the door position adjustment mechanism 100 is positioned to the side of the hinge H when the door D is closed, it is possible to prevent the door position adjustment mechanism 100 from interfering with the gasket positioned in front of the hinge H.

[0058] In addition, since door position adjustment mechanisms 100 are provided on both the upper and lower sides of door D, the load of door D can be supported by the door position adjustment mechanisms 100 at both the top and bottom, and furthermore, finer position adjustment of door D becomes possible.

[0059] Furthermore, since a multi-axis hinge H is used to rotate the door D while pushing it forward, it is possible to achieve a large opening angle for the door D while aligning the position of the design surface D1 with that of the adjacent cabinet, thus ensuring aesthetic appeal. On the other hand, unlike a single-axis hinge, a multi-axis hinge has multiple link members and multiple rotation axes. Therefore, the refrigerator R of this embodiment, which uses a multi-axis hinge, is more prone to door sagging compared to a refrigerator using a single-axis hinge. For this reason, the effects of the door position adjustment mechanism 100 according to the present invention are more pronounced in the refrigerator R of this embodiment, which uses a multi-axis hinge.

[0060] However, the present invention is not limited to the embodiments described above.

[0061] For example, the door position adjustment mechanism 100 in the above embodiment moved the door D not only in the vertical direction but also in the front-to-back and left-to-right directions. However, it is not necessarily required to move the door in the front-to-back direction, nor is it necessarily required to move it in the left-to-right direction.

[0062] Furthermore, in the above embodiment, an elongated hole h2 in the front-to-back direction was formed in the door base 20, but a through hole h3 in the front-to-back direction may also be formed as an elongated hole in the hinge base 30.

[0063] Furthermore, in the above embodiment, an elongated hole h5 extending in the left-right direction was formed in the slide plate 50, but an elongated hole extending in the left-right direction may also be formed in the hinge base 30.

[0064] Furthermore, the movement of door D in the front-to-back direction and / or the movement of door D in the left-to-right direction, or both, are not limited to the use of elongated holes, but may also be carried out using screw members, for example, in the same way as in the up-and-down direction, or even using eccentric cams or the like. Furthermore, a door position adjustment mechanism 100 that uses the screw member B3 to adjust the position of the door D in the front-to-back direction, for example, can be configured as shown in Figure 6.

[0065] Furthermore, as shown in Figure 6, the door position adjustment mechanism 100 may also have a guide section G that guides movement in the left-right or front-back direction.

[0066] Furthermore, although the slide plate 50 was interposed between the adjuster block 40 and the hinge base 30 in the above embodiment, it may also be interposed between the adjuster block 40 and the door base 20, as shown in Figure 6.

[0067] Furthermore, as shown in Figure 6, the front-to-back adjustment fixing screw B1 may be the same type of screw as the up-to-down adjustment screw 10, and similarly, although not shown, the left-to-right adjustment fixing screw B2 may also be the same type of screw as the up-to-down adjustment screw 10.

[0068] Furthermore, as shown in Figure 7, by changing the shape of the components of the hinge H, the components of the hinge H may be made to perform some of the functions of the door position adjustment mechanism 100 of the above embodiment. Specifically, the components of the hinge H extend towards the center of the door D, and a lateral elongated hole is formed in this extension H3, and the slide plate 50 is attached to the extension H3 through this elongated hole. With this configuration, the number of parts can be reduced, leading to lower costs and a more compact design.

[0069] Furthermore, as shown in Figure 7, the slide plate 50 may have a pressure-receiving surface on its front side by bending it. In addition, in Figure 7, the member attached to the extension H3 can also be seen as the hinge base 30, in which case the hinge base 30 is equipped with the function of the slide plate 50 in the above embodiment.

[0070] In the above embodiment, the door position adjustment mechanism 100 was positioned to the side of the hinge H when the door D was closed. However, as shown in Figure 8, the door position adjustment mechanism 100, which is positioned above the door D, may also be positioned below the hinge H. Furthermore, although not shown, the door position adjustment mechanism 100, which is positioned below the door D, may also be positioned above the hinge H.

[0071] Furthermore, although the above embodiment described a case where the door position adjustment mechanisms 100 provided on the upper and lower sides of the door D have a vertically symmetrical structure, these door position adjustment mechanisms 100 do not necessarily have the same configuration. For example, the upper door position adjustment mechanism 100 may be capable of adjusting the door D in three directions: up and down, left and right, and front and back, while the lower door position adjustment mechanism 100 may be capable of adjusting the door D in only one direction: up and down.

[0072] Furthermore, although the door position adjustment mechanism 100 was configured using a single adjuster block 40 in the above embodiment, the adjuster block 40 may be divided into multiple elements, as shown in Figures 9 and 10.

[0073] More specifically, the adjuster block 40 here consists of a first element 41 attached to the door base 20 and a second element 42 attached to the hinge base 30, with an up-and-down adjustment screw 10 interposed between the first element 41 and the second element 42.

[0074] The first element 41 is a small piece extending in the width direction of the door, and is provided in this case to abut against the lower surface of the door base 20.

[0075] The second element 42 is a small piece extending in the width direction of the door, and is provided so as to abut the upper surface of the hinge base 30, sandwiching the vertical adjustment screw 10 between it and the first element 41.

[0076] The vertical adjustment screw 10 is screwed into at least one of the first element 41 or the second element 42. In this case, it is screwed into the second element 42, and its head 12 is positioned to abut against the lower surface of the first element 41. In this example, the door base 20, the first element 41, the second element 42, and the hinge base 30 are unitized using multiple screw members B4, which are unified with the vertical adjustment screw 10.

[0077] The first element 41 and the door base 20 each have peepholes h7 and h8 positioned facing the head 12 of the vertical adjustment screw 10. By inserting a tool such as a wrench through these peepholes h7 and h8, the tool can be inserted into the tool hole 12h provided in the head 12, thereby tightening or loosening the vertical adjustment screw.

[0078] With this configuration, when the vertical adjustment screw 10 is loosened relative to the second element 42, the head 12 pushes up the first element 41, causing the door base 20 and door D to lift up together with the first element 41. On the other hand, when the vertical adjustment screw 10 is tightened relative to the second element 42, the door base 20 lowers along with the vertical adjustment screw 10, causing door D to lower.

[0079] Here, the door position adjustment mechanism 100 shown in Figures 9 and 10 is similar to the above embodiment in that it allows the door to be positioned horizontally using a left / right adjustment fixing screw B2 and an elongated hole h5 through which the screw passes. On the other hand, the door position adjustment mechanism of the above embodiment differs from the door position adjustment mechanism 100 shown in Figures 9 and 10 in that the direction in which the left and right adjustment fixing screws advance and retract is in the door height direction (up and down direction), whereas the direction in which the left and right adjustment fixing screws B2 advance and retract is in the door thickness direction (front and back direction).

[0080] Furthermore, while the door position adjustment mechanism of the above embodiment is configured to allow the door to be positioned in the front-rear direction using a front-rear adjustment fixing screw and an elongated hole, the door position adjustment mechanism 100 shown in Figures 9 and 10 differs in that it is configured to allow the door to be positioned in the front-rear direction by tightening or loosening the front-rear adjustment fixing screw B1.

[0081] Furthermore, the door position adjustment mechanism 100 shown in Figures 9 and 10 further includes a guide section G that guides the movement of the door, and in this case, the guide section G guides the movement of the door in the front-rear direction.

[0082] More specifically, the door position adjustment mechanism 100 is equipped with a guide plate GP that covers the door base 20 from above. Both ends of the guide plate GP in the width direction are bent downwards and clamp the door base 20 from the outside in the width direction, thereby performing the function of the guide part G described above.

[0083] As described above, the door position adjustment mechanism 100 shown in Figures 9 and 10 allows for stepless adjustment of the door in the vertical, horizontal, and front-to-back directions. For example, when applied to a built-in refrigerator, it eliminates door tilt and gaps between adjacent cabinets, thereby ensuring aesthetic appeal.

[0084] Furthermore, the door position adjustment mechanism 100 according to the present invention is not limited to use in refrigerators R, but may also be used in various cabinet products, such as clothing care devices for storing clothes. In particular, the door position adjustment mechanism 100 according to the present invention is effective for products in which it is not possible to place hinges H inside the cabinet.

[0085] Furthermore, it goes without saying that the present invention is not limited to the embodiments described above, and various modifications are possible without departing from its spirit. [Explanation of Symbols]
