Description

Technical Field

[0001] This disclosure relates to a housing and a household appliance, and more particularly to a refrigerator or garment care device having the housing. Background Technology

[0002] A refrigerator is typically a household appliance used to store food in a cold storage space shielded by a door by using cold air. To this end, refrigerators are constructed to cool the internal storage space by using cold air generated through heat exchange with the refrigerant circulating in the refrigeration cycle, thereby storing food in optimal condition.

[0003] A refrigerator can be placed independently in the kitchen or living room, or it can be a built-in household appliance housed within a space defined by kitchen furniture cabinets or surrounding cabinets.

[0004] A refrigerator may include a cabinet that forms a storage space and a door connected to the cabinet to open and close the storage space.

[0005] For example, if the refrigerator is installed inside a furniture cabinet, there is a risk that the door may hit the cabinet when it is opened, which may limit the opening angle of the door.

[0006] Recently, hinge structures have been developed to prevent doors from interfering with surrounding structures, such as furniture cabinets, when opened.

[0007] There is an international publication No. WO2019 / 007278A1 that exists as prior art literature.

[0008] At the same time, door height adjustment may be necessary to ensure that the height of multiple doors in the refrigerator is consistent.

[0009] There is a prior art document, Korean Patent Publication No. 10-2021-0123087. Summary of the Invention

[0045] The second body may include a first inclined surface, and the second component slides along the first inclined surface.

[0046] At least a portion of the second member is located between the third member and the second body, and the third member may include a second inclined surface along which the second member slides.

[0047] The second component may include a first contact surface that contacts the first inclined surface and a second contact surface that contacts the second inclined surface.

[0048] The door may also include a housing installed at the door and accommodating the first component, the second component, and the third component.

[0049] The housing moves up and down together with the second component. The housing moves relative to the first component and the third component.

[0050] The refrigerator may also include an automatic closing device disposed on one side of the guide member at the door and used to provide a closing force to the door during the door closing process.

[0051] The second component is located above the automatic closing device and can overlap with the automatic closing device in the vertical direction.

[0052] At least a portion of the third component is located above the automatic closing device and may overlap the automatic closing device in the vertical direction.

[0053] The height adjustment device may further include a fourth component for transmitting external operating force to the third component.

[0054] The automatic closing device can be positioned between the fourth component and the guide component.

[0055] The first direction can be downward, and the second direction can be upward.

[0056] According to another aspect, a refrigerator may further include: a body having a storage space; a door for opening and closing the storage space; a hinge mechanism allowing the door to rotate relative to the body; a height adjustment device disposed inside the door to adjust the height of the door; and an automatic closing device for providing a closing force to the door during the door closing process.

[0057] The hinge device may include a hinge body installed on the housing, a pin unit disposed on the hinge body, and a guide member disposed on the door and forming a pin groove, wherein the pin unit is accommodated in the pin groove.

[0058] The automatic closing device may include: a body mounted on the door and located on one side of the guide member; and a rod rotatable relative to the body and interacting with the hinge body. At least a portion of the height adjustment device may be positioned further away from the guide member than the rotation center of the rod.

[0064] The height adjustment device may include a first component housed in the housing and connected to the guide member, a second component movable relative to the first component, and a third component movable relative to the second component and movable up and down by an external operating force.

[0065] When the third component moves along the first direction, the second component and the housing can move upward, thereby increasing the height of the door. When the third component moves along the second direction, the second component and the housing can move downward, thereby decreasing the height of the door.

[0066] The structure described above for refrigerators can also be applied to household appliances.

[0067] Therefore, the height of the door can be easily adjusted by attaching a tool to the connection recess exposed to the outside of the door and operating the door when it is opened or closed.

[0068] Therefore, the door opening angle can be increased while preventing interference with surrounding structures during the door opening process.

[0069] Therefore, the height adjustment device is positioned inside the door, with the connecting recess exposed to the outside, thereby minimizing the exposure of the height adjustment device to the outside.

[0070] Therefore, during the closing process, the door can be automatically closed by the automatic closing device, and the height adjustment device for adjusting the height is located near the automatic closing device, which has the advantage of being compact and not interfering with the automatic closing device.

[0071] Of course, the present invention can be applied to other household appliances besides refrigerators, such as clothing care equipment, such as garment fresheners, hair dryers, washing machines or dryers. Attached Figure Description

[0088] In the following, some embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that when components in the drawings are indicated by reference numerals, the same components will be represented by the same reference numerals as much as possible, even if shown in different drawings. Furthermore, in the description of embodiments of the present disclosure, detailed descriptions will be omitted when it is determined that detailed descriptions of well-known configurations or functions would interfere with the understanding of embodiments of the present disclosure.

[0089] Furthermore, in the description of embodiments of this disclosure, terms such as first, second, A, B, (a), and (b) may be used. Each of these terms is used only to distinguish the corresponding component from other components and does not limit the nature, order, or sequence of the corresponding components. It should be understood that when one component is "connected," "joined," or "engaged" to another component, the former may be directly connected, joined, or engaged to the latter, or may be "connected," "joined," or "engaged" to the latter by the insertion of a third component.

[0090] The following explanation uses a refrigerator as an example of a household appliance. However, the structure and height adjustment device used to rotate the refrigerator door can also be applied to other household appliances or storage cabinets besides refrigerators.

[0091] Figure 1 This is a perspective view of the refrigerator according to the first embodiment. Figure 2 This is a diagram showing the first hinge device according to the first embodiment. Figure 3 This is a bottom view of the first door in the first embodiment.

[0092] Reference Figures 1 to 3 The refrigerator 1 of this embodiment can be set up independently in the kitchen or housed in an indoor furniture cabinet (hereinafter collectively referred to as "furniture cabinet").

[0093] When refrigerator 1 is installed inside an indoor furniture cabinet, it can be installed independently or arranged side-by-side with another refrigerator, kitchen shelf, or cabinet. Therefore, the position of the door relative to adjacent cabinets or their front panels is important for adjusting gap dimensions.

[0094] Refrigerator 1 may also have a cabinet with storage space. The cabinet may have a main body 10 that defines the storage space. Refrigerator 1 may also include a door 20 that opens and closes the storage space and provides thermal shielding for the storage space.

[0095] The storage space can be divided into an upper first space and a lower second space, but is not limited thereto. Door 20 may also include a first door 21 for opening and closing the first space and a second door 22 for opening and closing the second space.

[0096] The first space can be a refrigerator compartment and the second space can be a freezer compartment, or vice versa, or there can be two refrigerator compartments or two freezer compartments. Alternatively, the storage space can include a first space and a second space separated to the left and right. Alternatively, the storage space can be a single space with a single door that can be opened and closed.

[0097] At least one of the first door 21 or the second door 22 can be a revolving door. Alternatively, a single door 20 can be a revolving door.

[0098] The revolving door 20 will be described below using the first door 21 as an example. Here, the first door 21 can be rotatably connected to the main body 10 of the box via a hinge device.

[0099] The hinge device may include a first hinge device 40 located on the lower side of the first door 21 and a second hinge device located on the upper side of the first door 21.

[0100] The first hinge device 40 and the second hinge device have the same structure for rotating the first door 21, but the structures for installation in or at the box body 10 are different.

[0101] For example, the shape or structure of the hinge body of the first hinge device 40 and the second hinge device can be different.

[0102] The following explanation will take the first hinge device 40 as an example.

[0103] The first door 21 may include a pair of doors arranged side by side. The exterior of the pair of doors may be symmetrical or at least substantially symmetrical. Furthermore, each of the pair of doors may be rotatably connected to the housing body 10 via a hinge mechanism.

[0104] One of the doors in a pair may be equipped with a dispenser 23 for distributing water and / or ice. Of course, the dispenser 23 may be omitted.

[0105] The first door 21 may include a front panel 210 that forms the front appearance. The first door 21 may also include a door frame 220 that is attached to the front panel 210 and forms the lower appearance of the first door 21.

[0106] As can be clearly seen from the above, neither refrigeration function nor the number of doors is a necessary condition. Therefore, the invention can be applied to any container having a storage compartment that can be closed by a door, provided that the door is rotatably connected to the enclosure surrounding the storage compartment via a hinged mechanism. Thus, there may be only one door.

[0107] The door frame 220 may include a first surface 221. The first surface 221 may include a portion facing the hinge assembly 40 or the hinge body 410, as will be described later. Thus, the hinge assembly may be primarily attached to the first surface. The first surface 221 may form the lowest surface of the door and may face the floor or bottom surface.

[0108] The door frame 220 may also include a second surface 222 that is stepped relative to the first surface 221. The second surface 222 may, for example, be positioned above the first surface 221.

[0109] The door frame 220 may also include a third surface 223 connecting the first surface 221 and the second surface 222. The third surface 223 may form part of the front appearance of the first door 21.

[0110] For example, the first surface 221 and the second surface 222 may be horizontal planes or planes inclined at a predetermined angle from the horizontal plane. The third surface 223 may be a plane extending substantially vertically or a vertical plane.

[0111] The door frame 220 may include a handle 230 for a user to grip. The handle 230 may be formed, for example, by making a portion of the second surface 222 recessed upward.

[0112] The first hinge device 40 may include a hinge body 410. The hinge body 410 may be attached to a surface of the housing body 10, preferably to a vertical surface. The surface may be, for example, the front surface of the housing body 10. A portion of the hinge body 410 may overlap the lower side of the first door 21 in the vertical direction.

[0113] The hinge body 410 can support the load of the first door 21. The hinge body 410 may include, for example, a connecting portion 411 connected to the housing body 10 and an extension 412 extending from the connecting portion 411.

[0114] The connecting portion 411 may be connected to the front surface of the housing body 10, for example. One or more connecting holes 411a may be formed in the connecting portion 411.

[0115] When the refrigerator 1 is installed in a furniture cabinet or kitchen, it is necessary to increase the opening angle of the first door 21 during the opening process without interfering with the furniture cabinet or surrounding structure.

[0116] In this embodiment, the first hinge device 40 and the second hinge device can increase the opening angle of the first door 21 without interfering with the furniture cabinet or surrounding structure. For example, the first hinge device 40 and the second hinge device can move the rotation center of the first door 21 during at least one stage of the entire opening process of the first door 21. Here, a stage refers to a portion of the door opening stroke.

[0117] In the case where the second door 22 is a rotating type, the first hinge device 40 described below is also applicable to the second door 22.

[0118] The first hinge device 40 may also include a pin unit 420.

[0119] The pin unit 420 may include a first pin 421 and a second pin 422. The first pin 421 and the second pin 422 may be spaced apart from the hinge body 410. The first pin 421 and the second pin 422 may be integrally formed with the hinge body 410 or may be connected to the hinge body 410.

[0120] For example, the first pin 421 and the second pin 422 can extend from the hinge body 410 toward the first door 21. The first pin 421 and the second pin 422 can extend upward from the hinge body 410. For example, the pin unit 420 can be provided at the extension 412 of the hinge body 410.

[0121] The second hinge device may further include a first pin and a second pin, and the first pin 421 and the second pin 422 of the first hinge device 40 may be vertically aligned with the first pin and the second pin of the second hinge device.

[0122] The first door 21 may also include a pin groove 272 in which a pin unit 420 (i.e., at least one of its pins) is received. The pin groove 272 may be located on the underside of the first door 21. The pin groove 272 may be formed on the lower surface of the first door 21 and recessed upwards. Therefore, the pin groove 272 may be a recess or a slit. The pin groove 272 may be formed by a guide member 270. That is, the guide member 270 may include a recessed pin groove 272, i.e., a groove in the guide member 270. The guide member 270 may be connected to the underside of the first door 21. For example, the guide member 270 may be connected to the door frame 220, i.e., the lower part of the door.

[0123] The first pin 421 and the second pin 422 may be formed in a cylindrical shape. The first pin 421 and the second pin 422 may include flanges with an enlarged diameter. The flanges may contact the hinge body 410. For example, each of the first pin 421 and the second pin 422 may include a first portion received in a pin groove 272 and a second portion (or flange) positioned below the first portion and outside the pin groove 272. A guide member 270 may be mounted on the extension 412 or on the flange.

[0124] The pin groove 272 may be formed or comprise a curve. The curvature of the pin groove 272 may vary gradually or continuously. When the curvature of the pin groove 272 is gradually variable, the pin groove 272 may be divided into multiple parts. The curvature of each of the multiple parts may be different from each other. As described above, the curvature of the pin groove 272 defines the movement of the rotation center of the door.

[0125] The first door 21 can be opened with the first pin 421 and the second pin 422 accommodated in the pin groove 272. The rotation center of the first door 21 can move according to the shape of the pin groove 272. The rotation center of the first door 21 can be, for example, an imaginary rotation center. Depending on the shape of the pin groove 272, the rotation center can move continuously or gradually.

[0126] By moving the rotation center of the first door 21, the opening angle of the first door 21 can be adjusted or increased during the opening process without interfering with the furniture cabinet or surrounding structure.

[0127] The refrigerator 1 may also include a stop member 280. The stop member 280 can restrict the rotation of the first door 21 when the first door 21 is opened to its maximum opening angle.

[0128] The stop member 280 may be installed, for example, on the underside of the first door 21. The stop member 280 may be installed at the door frame 220.

[0129] The stop member 280 may include a stop 282. The stop 282 may extend in the vertical direction. When the stop 282 contacts a point of the extension 412 of the hinge body 410 during the opening process of the first door 21, the opening of the first door 21 can be restricted.

[0130] The refrigerator 1 may also include an automatic closing device 60, which provides a closing force to the first door 21 when the first door 21 is closed. Of course, the automatic closing device 60 may be omitted.

[0131] The automatic closing device 60 can be installed, for example, at the door frame 220. The automatic closing device 60 can be attached to the first surface 221 of the door frame 220.

[0132] The automatic closing device 60 can provide a closing force to the first door 21 while interacting with the hinge body 410 during the closing process of the first door 21.

[0133] The automatic closing device 60 can be installed at the first door 21 at a position adjacent to the hinge body 410.

[0134] The automatic closing device 60 may include a main body 610 installed at the door frame 220.

[0135] The automatic closing device 60 may include a rod 620 movably mounted on the body 610. For example, the rod 620 may rotate relative to the body 610 based on a rotation center A1. The rod 620 may be movably connected to the body 610 while being elastically supported. For example, the automatic closing device 60 may also include an elastic member (not shown) for elastically supporting the rod 620. The elastic member may be directly or indirectly connected to the rod 620 within the body 610.

[0136] The lever 620 may also include a contact portion 622 that will come into contact with the hinge body 410. The contact portion 622 may be, for example, a rotatable roller or a deformable component.

[0137] When the door 20 is closed while the elastic member connected to the rod 620 has accumulated elastic force, the elastic force acts as a closing force on the first door 21, enabling the first door 21 to be closed automatically.

[0138] The extension 412 may include a contact surface for interacting with the contact portion 622. The contact surface may include a first contact surface 431, a second contact surface 432, and a third contact surface 433. The second contact surface 432 may be inclined relative to the first contact surface 431. The third contact surface 433 may be inclined relative to the second contact surface 432.

[0139] When the first door 21 is open at an angle greater than the set angle, the contact portion 622 does not contact the first contact surface 431. When the first door 21 is closed at an angle less than the set angle, the contact portion 622 can contact the first contact surface 431.

[0140] When the first door 21 is closed, the contact portion 622 moves along the second contact surface 432, thereby providing a closing force to the first door 21 so that the first door 21 can be closed automatically.

[0141] When the first door 21 is fully closed, the contact portion 622 can come into contact with the third contact surface 433.

[0142] The refrigerator 1 may include a height adjustment device (described below) for adjusting the height of the first door 21. For example, the height of the lower surface of the first door 21 relative to the extension 412 may be adjusted by the height adjustment device.

[0143] The first door 21 can be equipped with an opening 232. Figure 9A The tool used to operate the height adjustment device 50 can pass through the opening 232.

[0144] The height adjustment device 50 can be positioned adjacent to the hinge device 40. The opening 232 can be formed in the door frame 220. As an example, Figure 3 An opening 232 is shown to be formed in the first surface 221 of the door frame 220.

[0145] The height adjustment device 50 will now be described in detail.

[0146] Figure 4 This is a perspective view showing the door frame 200 and the height adjustment device 50 of the first embodiment. Figure 5This is an exploded perspective view showing the configuration of the door frame 220, the height adjustment device 50, and the hinge device 40 according to the first embodiment. Figure 6 This is an exploded perspective view of the height adjustment device according to the first embodiment. Figure 7 This is a front view of the height adjustment device 50 according to the first embodiment. Figure 8 It is along Figure 3 The sectional view taken from line 8-8.

[0147] refer to Figures 4 to 8 In one embodiment, the guide member 270 may be positioned at or inside the first door 21 and may move relative to the first door 21.

[0148] When the height adjustment device 50 of this embodiment is operated, the first door 21 can rise or fall while the guide member 270 is supported by the flange or extension 412 of the hinge body 410.

[0149] The height adjustment device 50 may include a first component 510.

[0150] The first component 510 may be connected to or integrally formed with the guide component 270.

[0151] The first component 510 may be a fixed component whose position is fixed during the height adjustment process. The first component 510 may include a first body 512 extending upward from the guide component 270 and a second body 514 extending horizontally from the first body 512.

[0152] At least a portion of the second body 514 may not overlap with the guide member 270 in the vertical direction. The second body 514 may be positioned above the pin groove 272.

[0153] The second body 514 may include a first inclined surface 515. The inclined surface 515 may, for example, be inclined in a direction away from the first body 512 from the upper side to the lower side. Therefore, the first inclined surface 515 may face the lower part of the door.

[0154] The second body 514 may include a first stop 516 located on the upper side of the first inclined surface 515 and a second stop 517 located on the lower side of the first inclined surface 515. The first stop 516 and the second stop 517 may protrude from the first inclined surface 515.

[0155] On the other hand, a recess may be formed in the second body 514, and the recessed surface may be an inclined surface. The upper and lower walls forming the recess can be used as stops.

[0156] The height adjustment device 50 may also include a second component 520. The second component 520 may be movable relative to the first component 510.

[0157] The second member 520 may include a portion extending in a horizontal direction. At least a portion of the second member 520 may be positioned above the automatic closing device 60. At least a portion of the second member 520 may overlap with the automatic closing device 60 in a vertical direction.

[0158] Therefore, interference between the second component 520 and the automatic shut-off device 60 can be prevented during the operation of the second component 520.

[0159] The height adjustment device 50 may further include a third component 530. The third component 530 is movable relative to the second component 520. The third component 530 can move up and down due to an external operating force.

[0160] The second component 520 and the third component 530 can be movable components whose positions can be changed during height adjustment.

[0161] At this time, during the height adjustment process, the third component 530 can move only in the vertical direction. Conversely, during the height adjustment process, the second component 520 can move in both the vertical and horizontal directions.

[0162] The second component 520 can be positioned between the first component 510 and the third component 530.

[0163] At least a portion of the third component 530 may be positioned above the automatic closing device 60. At least a portion of the third component 530 may overlap with the automatic closing device 60 in the vertical direction.

[0164] With this arrangement, the components constituting the height adjustment device 50 can be located near the hinge device 40 and the automatic closing device 60. The height adjustment device 50 can be compact.

[0165] According to the above arrangement, the length of the second component 520 can be reduced, thereby reducing the possibility of damage to the second component 520 during operation and improving power transmission efficiency.

[0166] The third member 530 may include a second inclined surface 532. The second inclined surface 532 may be inclined in a direction closer to the first member 510 as it moves from the lower side to the upper side. Therefore, the second inclined surface faces downward toward the bottom.

[0167] The inclination of the first inclined surface 515 can be the same as the inclination of the second inclined surface 532.

[0168] The third component 530 may include a first stop 533 located on the upper side of the second inclined surface 532 and a second stop 534 located on the lower side of the second inclined surface 532. The first stop 533 and the second stop 534 may protrude from the first inclined surface 532.

[0169] The third component 530 may have a recess, and the recessed surface may be an inclined surface. The upper and lower walls forming the recess may serve as stops.

[0170] The second component 520 may include a first contact surface 522 that contacts the first inclined surface 515. The length of the first contact surface 522 may be less than the length of the first inclined surface 515.

[0171] With the height of the first door 21 adjusted to its maximum height, the second component 520 can contact the first stop 516 of the first component 510.

[0172] With the height of the first door 21 adjusted to its minimum, the second component 520 can contact the second stop 517 of the first component 510.

[0173] The second member 520 may further include a second contact surface 524 that contacts the second inclined surface 532. The length of the second contact surface 524 may be less than the length of the second inclined surface 532.

[0174] With the height of the first door 21 adjusted to its maximum height, the second component 520 can contact the first stop 533 of the third component 530.

[0175] When the height of the first door 21 is adjusted to the minimum height, the second component 520 can contact the second stop 534 of the third component 530.

[0176] The height adjustment device 50 may also include a fourth member 540. The fourth member 540 may be rotatable relative to the third member 530. The fourth member 540 may be a tool-operated member and may be referred to as an operating member. Alternatively, the fourth member 540 may be a transmission member that transmits external operating force to the third member 530.

[0177] For example, the fourth component 540 may be a screw and / or may be rotatably connected to the third component 530.

[0178] The automatic closing device 60 can be positioned between the fourth component 540 and the guide component 270.

[0179] The tools used by the user can be connected to the fourth component 540.

[0180] The fourth component 540 may include a main body portion 544 connected to the third component 530 and a head portion 542 located below the main body portion 544. The diameter of the head portion 542 may be larger than the diameter of the main body portion 544.

[0181] Threads may be formed on the outer surface of the main body portion 544. A connecting hole 531 may be formed in the third member 530 to connect the main body portion 544. Threads that engage with the threaded part of the main body portion 544 may be formed on the surface forming the connecting hole 531.

[0182] The head portion 542 may be provided with a connecting recess 543 to which a tool is connected.

[0183] The connecting recess 543 can be, for example, a hexagonal groove, but is not limited to this.

[0184] The connecting recess 543 can be aligned with the opening 232. In this case, a tool can be connected to the connecting recess 543 by passing through the opening 232. In this embodiment, the connecting recess 543 in the height adjustment device 50 is exposed to the outside through the opening 232. Therefore, according to this embodiment, the exposure of the height adjustment device 50 to the outside of the first door 21 can be minimized.

[0185] Alternatively, the head portion 542 can be positioned within the opening 232. That is, the connecting recess 543 can also be located within the opening 232. In this case, the tool can be connected to the connecting recess 543 located within the opening 232.

[0186] In both of the above cases, since the fourth component 540 can be located inside the first door 21, the exposure of the height adjustment device 50 can be minimized.

[0187] As another example, the head portion 542 can be positioned outside the first door 21. In this case, the body of the fourth member 540 can be connected to the third member 530 through the opening 232. The tool can be connected to the connecting recess 543 located outside the first door 21.

[0188] Meanwhile, the door frame 220 may include a first wall 231 forming the handle 220.

[0189] The door frame 220 may also include a second wall 234, which forms a receiving space for accommodating the automatic closing device 60. The second wall 234 may be positioned spaced apart from the first wall 231.

[0190] The door frame 220 may also include a third wall 235, which forms a space in which the guide member 270 is positioned. The third wall 235 may be positioned spaced apart from the second wall 234.

[0191] The first door 21 may also include a housing 550 that accommodates the height adjustment device 50.

[0192] The housing 550 can be connected to the door frame 220. The guide member 270 can pass through the space formed by the third wall 235.

[0193] The height of the housing 550 can be adjusted by the height adjustment device 50. Since the housing 550 is connected to the door frame 220 and exists as a single component together with the first door 21, the height of the first door 21 can be adjusted when the housing 550 moves up and down.

[0194] The housing 550 may include a first housing 560 and a second housing 562 connected to each other.

[0195] The first housing 560 and the second housing 562 can be connected to form a space in which the first component 510, the second component 520 and the third component 530 are positioned.

[0196] The space may include a first space 574 in which a first component 510 is positioned, a second space 575 in which a second component 520 is positioned, and a third space 576 in which a third component 530 is positioned.

[0197] Each of the first housing 560 and the second housing 562 may include a first portion 571 forming a first space 574, a second portion 572 forming a second space 575, and a third portion 573 forming a third space 576.

[0198] At least one of the first housing 560 or the second housing 562 may include a connecting portion 564 for connection to the door frame 220.

[0199] The left and right width (e.g., maximum width) of the first space 574 can be configured to correspond to the left and right width (e.g., maximum width) of the first member 510. The vertical length of the first space 574 can be configured to be greater than the vertical length of the first member 510.

[0200] Therefore, when the first component 510 is located in the first space 574, the left and right movement of the housing 550 is restricted, while the vertical movement of the housing 550 is possible.

[0201] The vertical length of the second space 575 can be configured to correspond to the vertical length of the second member 520. Therefore, with the second member 520 located in the second space 575, the housing 550 can move vertically together with the vertical movement of the second member 520. Furthermore, the second member 520 can move in the left-right direction within the second space 575 as shown in the figure.

[0202] The left and right width (e.g., maximum width) of the third space 576 can be configured to correspond to the left and right width (e.g., maximum width) of the third member 530. The vertical length of the third space 576 can be configured to be greater than the vertical length of the third member 530.

[0203] Therefore, with the third component 530 located in the third space 576, the left and right movement of the housing 550 is restricted, but the vertical movement of the housing 550 is possible.

[0204] At least a portion of the main body 544 of the fourth component 540 may be positioned within the third space 576. The head portion 542 may be positioned outside the third space 576.

[0205] Meanwhile, the door liner 250 can be positioned on the rear side of the front panel 210. The door liner 250 can be connected to the door frame 220.

[0206] The front panel 210, door liner 250, and door frame 220 can form an insulating space into which foaming liquid can be injected.

[0207] The foaming liquid injected into the insulating space can be hardened to form an insulator. At this time, since the height adjustment device 50 is housed inside the housing 550, contact between the insulator and the height adjustment device 50 can be prevented, and the height adjustment device 50 can operate stably.

[0208] The first door 21 may also include a plate 240 connected to the door frame 220. The plate 240 may include a shielding portion 242 covering the stop 282.

[0209] The shielding portion 242 can be positioned in front of the stop 282 by passing through one side of the door frame 220. As another example, there may be no separate plate 240, and only the shielding portion 242 extends from the door frame 220. The shielding portion 242 reduces the exposure of the stop 282 relative to the front side of the first door 21.

[0210] Figures 9A to 9C This is a diagram showing the relative positions of the housing and the height adjustment device 50 when adjusting the height of the first door 21 according to the first embodiment. Figures 10A to 10C This is a diagram showing the relative positions of the housing 550 and the guide member 270 of the first door 21 when the height of the first door 21 is adjusted according to the first embodiment.

[0211] based on Figure 9B , Figure 9A This shows the state where the height of the first door 21 decreases. Figure 9C This shows the state where the height of the first gate 21 has increased.

[0212] based on Figure 10B, Figure 10A This shows the state where the height of the first door 21 decreases. Figure 10C This shows the state where the height of the first gate 21 has increased.

[0213] refer to Figures 4 to 10C In order to adjust the height of the first door 21, when the first door 21 is in the closed or open state, the user can connect the tool to the connecting recess 543 of the fourth component 540.

[0214] The tool can be rotated in one direction to decrease the height of the first door 21. The tool can be rotated in another direction to increase the height of the first door 21.

[0215] In such Figure 9B In this state, when the tool rotates in one direction, the fourth component 540 can rotate in one direction.

[0216] Since the third member 530 is positioned in the third space 576 in a polygonal shape, the rotation of the third member 530 is restricted when the fourth member 540 rotates in one direction, and in response to the rotation of the fourth member 540, the third member 530 moves in direction A within the housing 550, causing the third member 530 to move upward.

[0217] When the third member 530 moves upward, the second inclined surface 532 of the third member 530 also moves upward. Then, the force pressing the second contact surface 524 is removed, and the second member 520 moves in direction C and downward in direction B. For example, when the third member 530 rises, the second member 520 moves downward due to the loads from the first door 21 and the second member 520, causing the second member 520 to move in direction C.

[0218] Then, finally, the housing 550 moves in direction B, as follows: Figure 9A and Figure 10C As shown in B, the height of the first gate 21 decreases.

[0219] On the one hand, in such Figure 9B In this state, when the tool rotates in another direction, the fourth component 540 can rotate in the other direction.

[0220] Since the third member 530 is positioned in a polygonal shape within the third space 576, its rotation is restricted when the fourth member 540 rotates in the opposite direction. In response to the rotation of the fourth member 540, the third member 530 moves within the housing 550 in direction B, causing it to move downwards. As the third member 530 moves downwards, its second inclined surface 532 also moves downwards. Then, the second contact surface 524 slides together with the second inclined surface 532, causing the second member 520 to move in direction D.

[0221] When the second component 520 moves along direction D, the first contact surface 522 of the second component 520 slides along the first inclined surface 515, causing the second component 520 to move upward.

[0222] Then, the housing 550 eventually moves along direction A, thereby increasing the height of the first door 21, as... Figure 9C and Figure 10C As shown.

[0223] Figure 11 This is a diagram showing the location of the opening to which the height adjustment tool at the first door is connected, according to the second embodiment. Figure 12 and Figure 13 This is a diagram showing the height adjustment device according to the second embodiment.

[0224] Except for the location of the opening through which the height adjustment tool passes and the structure of the height adjustment device, this embodiment is identical to the first embodiment in all other respects. Therefore, the characteristic parts of this embodiment will be described below, and the same reference numerals will be used for the same constituent elements as in the first embodiment.

[0225] Reference Figures 11 to 13 In the first embodiment, an opening for a height-adjusting tool formed in the first surface 221 of the door frame 220 was described. However, in the second embodiment, an opening 232a for a height-adjusting tool can be formed in the third surface 223 of the door frame 220. In this case, the tool can be easily accessed through the opening 232a without opening the first door 21.

[0226] The height adjustment device 50A of the second embodiment may include a first component 510, a second component 520 and a third component 530a.

[0227] The shape and operation of the first component 510 and the second component 520 are the same as in the first embodiment, so their detailed description will be omitted.

[0228] The basic shape of the third member 530a can be the same as that of the third member 530 in the first embodiment. However, in the second embodiment, the third member 530a may include a rack 536 on which gear teeth are formed. For example, the rack 536 may extend downward from the third member 530a. That is, the rack 536 may extend in a vertical direction.

[0229] The height adjustment device 50A may also include a pinion 538 connected to the rack 536.

[0230] The height adjustment device 50A may further include an operating member 540a connected to the pinion 538. The operating member 540a may also be referred to as the fourth member. The operating member 540a may be formed with the same shape as the fourth member 540 of the first embodiment. That is, the operating member 540a may also include a head portion and a body portion, with a connecting recess formed in the head portion. The connecting recess in the head portion may be aligned with the opening 232a. The arrangement relationship between the connecting recess and the opening 232a may be the same as the arrangement relationship between the connecting recess and the opening described in the first embodiment.

[0231] The operating component 540a can be arranged, for example, in a horizontal direction.

[0232] The third component 530a can move vertically by rotating the pinion 538.

[0233] In the second embodiment, the first component 510, the second component 520, and the third component 530a can be housed within the housing 550 as described in the first embodiment. On the other hand, the pinion 538 and the operating component 540a can be located inside or outside the housing 550.

[0234] Figure 14 This is a diagram showing the location of the opening for the tool in the third embodiment. Figure 15 This is a diagram showing the location of the opening for the tool in the fourth embodiment. Figure 16 This is a diagram showing the location of the opening for the tool in the fifth embodiment.

[0235] First refer to Figure 14 An opening 232b for the tool can be formed in the second surface 222 of the door frame 220. In this case, the opening 232b can be located in the area between the automatic closing device 60 and the handle 230.

[0236] Depending on the position of the opening 232b in the third embodiment, the shape or size of at least the third member 530 of the height adjustment device can be changed, and the length of the second member 520 can be increased.

[0237] Next, refer to Figure 15 Alternatively, the handle 230 can be removed from the first door 21, and the opening 232c can be formed at the location where the handle 230 is. Alternatively, the opening 232c can be formed in the wall forming the handle 230 within a range that does not interfere with the structure surrounding the handle 230. For example, if a light-emitting portion for emitting light to the handle 230 exists around the handle 230, the opening 232c can be formed at a location that does not interfere with the light-emitting portion.

[0238] In other words, when the first door 21 is divided into two halves in the left-right direction, the guide member 270 and the automatic closing device 60 can be located in the left region, and the opening 232c can be located in the right region. In this case, the third member 530 can be located in the right region. A portion of the second member 520 can also be located in the right region. Therefore, interference between the height adjustment device 50 and the automatic closing device 60 is avoided. Furthermore, the accessibility of the opening for adjusting the height of the door 21 is improved.

[0239] Now for reference Figure 16 The opening 232d for the tool can be positioned on the opposite side of the automatic closing device 60 relative to the handle 230. That is, the handle 230 can be located between the opening 232d and the automatic closing device 60.

[0240] In the above embodiment, the first door 21 is described as a single door. However, even if the first door 21 includes a main door connected to the housing body 10 and a secondary door that can rotate relative to the main door, the height adjustment device described above can still be used. That is, the height adjustment device can be located at the main door, and the opening for tools can also be located at various positions on the main door.

[0241] In summary, the size and / or position of the height adjustment device can be changed according to the change in the opening position. However, typically, a portion of the height adjustment device (or opening) can be positioned further away from the guide member 270 than the rotation center A1 of the lever 620. Furthermore, typically, a portion of the height adjustment device can overlap with the automatic closing device in the vertical direction.

[0242] Figure 17 This is a diagram illustrating a hinge device according to a sixth embodiment. Except for the shape of the guide member, this sixth embodiment is identical to the first embodiment in all other respects. Therefore, only the characteristic parts of this embodiment will be described below.

[0243] Reference Figure 17 The hinge device of the sixth embodiment may include an upper hinge device 90 and a lower hinge device 950.

[0244] The upper hinge device 90 may include a first hinge body 910 and a first pin unit 920.

[0245] The first pin unit 920 may extend, for example, from the first hinge body 910 toward the first door 21. The first pin unit 920 may extend downward from the first hinge body 910.

[0246] The first pin unit 920 may include a first pin 921 and a second pin 922. The first pin 921 and the second pin 922 may be spaced apart from each other in the first hinge body 910.

[0247] The basic shape and function of the first pin 921 and the second pin 922 are the same as those of the first pin and the second pin in the first embodiment, so their detailed description will be omitted.

[0248] The upper hinge device 90 may include a first guide member 930. The first guide member 930 may be disposed on the first door 21. The first guide member 930 may form a first pin groove.

[0249] The first pin groove may include a first groove 942 for receiving a first pin 921 and a second groove 944 for receiving a second pin 922. The first groove 942 and the second groove 944 may be spaced apart from each other and separate from each other.

[0250] The first guide member 930 may include an extension 931 for connection to the first door 21. A connection hole 932 may be formed for a connecting member to pass through the extension 931. The connecting member can be connected to the first door 21 by passing through the connection hole 932.

[0251] The first guide member 930 may include a first main body portion 933 forming a first slot 942 and a second main body portion 934 forming a second slot 944. The first main body portion 933 and the second main body portion 934 may extend from the extension portion 931.

[0252] The lower hinge device 950 of this embodiment may include a second hinge body and a second pin unit 960.

[0253] The second hinge body may include, for example, a connecting portion 951 connected to the housing body 10 and an extension portion 952 extending from the connecting portion 951. A second pin unit 960 may be disposed in the extension portion 952.

[0254] The second pin unit 960 may extend upward from the extension 952, for example.

[0255] The second pin unit 960 may include a first pin 961 and a second pin 962. The first pin 961 and the second pin 962 may be spaced apart from the extension 952.

[0256] The lower hinge device 950 may also include a second guide member 970. The second guide member 970 may be disposed at the first door 21.

[0257] The second guide member 970 can form a second pin groove.

[0258] The second pin groove may include a first slot 982 that receives the first pin 961 and a second slot 984 that receives the second pin 962. The first slot 982 and the second slot 984 may be spaced apart from each other and separate from each other.

[0259] The second guide member 970 may include an extension 971 that is connected to the first door 21. A connection hole 972 through which a connecting member passes may be formed in the extension 971. The connecting member can be connected to the first door 21 by passing through the connection hole 972.

[0260] The second guide member 970 may include a first body portion 973 forming a first slot 982 and a second body portion 974 forming a second slot 984. The first body portion 973 and the second body portion 974 may extend from the extension portion 971.

[0261] Even in the sixth embodiment, the rotation center of the first door 21 can be moved by the upper hinge device 90 and the lower hinge device 950.

[0262] This disclosure includes non-restrictive examples of the following provisions:
