Description

Insulator

[0001] The present invention relates to an insulator. The present invention relates to a refrigerator equipped with an insulator.

[0002] As a related prior art for solving the door sagging problem, Korean Patent No. 10-1432301 (announced on August 20, 2014; hereinafter, “patent document”) discloses a refrigerator that prevents the door from sagging by reinforcing the rigidity of the bracket. The refrigerator of the patent document includes a bracket coupled to a hinge, side reinforcing members provided at both corners of the main body and connected to the bracket, and a reinforcing part formed by bending a predetermined portion of the bottom surface of the bracket upward so as to be connected to the surface of the bracket and the bottom surface. When the bracket, side reinforcing members, and reinforcing part of the patent document are applied to a conventional foam-insulated refrigerator, they can be joined by drilling holes in the foam or the main body. However, when applied to a vacuum-insulated refrigerator, there is a concern of vacuum leakage when welding or drilling holes on a portion of the surface of the main body. When the first case of a vacuum insulation body made of metal material is increased beyond a certain thickness for strength reinforcement, the insulation performance is reduced due to heat transfer through the first case, so there is a problem that it is difficult to satisfy both the improvement of insulation performance and the reinforcement of strength.

[0003] The purpose of the present invention is to provide a refrigerator having a structure capable of solving the above-described problems.

[0004] The first objective is to provide a refrigerator having a structure that can prevent sagging of the door by reinforcing the strength of the hinge while maintaining the insulation performance of the body composed of a vacuum insulator.

[0005] The second purpose is to provide a refrigerator having a structure capable of preventing cold air leakage and / or vacuum leakage due to deformation of a first case made of metal.

[0006] The third purpose is to provide a refrigerator having a structure that can secure additional strength of the hinge.

The second insulator may be provided as a separate component separated from the first insulator. The second insulator may be connected to the first insulator by a connecting member. In the present invention, the connecting member may be defined as a joint. The second insulator may include a portion extending in the same direction as the first insulator. The second insulator may include a portion extending in a direction different from the first insulator. The insulator may be provided in the form of a panel.

[0013] The above hinge reinforcement frame may include a second frame portion formed to protrude in one direction from a portion (e.g., the upper portion) of the first frame portion.

[0014] A hinge reinforcing plate may be accommodated in the fourth panel. The fourth panel may form one side of the main body.

The second frame portion may be coupled to the fourth panel and / or the hinge reinforcing plate by a second coupling member.

[0015] The support frame may be extended to support one side of the fourth panel. The support frame may include a first coupling portion and / or a second coupling portion. A support frame may further be provided that extends to support one side of the fourth panel forming the side of the main body among the at least two panels.

The first coupling portion may be coupled to the side of the first panel forming the first side of the main body among the at least two panels. The second frame portion may be arranged to overlap the first coupling portion and be coupled to the first coupling portion.

[0016] The support frame may include a second coupling portion extending from the first coupling portion. The support frame may include a coupling portion coupled to a cover forming one side of the machine room.

[0017] The above hinge reinforcement frame may include a third frame portion formed to protrude from one end of the second frame portion. A support frame may be provided that is coupled to a portion of a cover forming one side of the machine room. The third frame portion may be coupled to the surface of the support frame by a third coupling member.

[0018] The above hinge reinforcement frame may include a fourth frame portion formed to protrude from one end of the first frame portion.

[0019] The above hinge reinforcement frame may include at least one of a first frame portion; a second frame portion formed to be bent at a first end of the first frame portion; a third frame portion formed to be bent at one end of the second frame portion; and a fourth frame portion formed to be bent at a second end of the first frame portion.

[0020] At least one of the first frame portion to the fourth frame portion may be formed in the shape of a plate having a constant thickness. It may be provided in a shape with one side open.

[0021] The first connecting member may be positioned lower than the second connecting member penetrating the second frame portion and / or the third connecting member penetrating the third frame portion.

[0022] The at least two panels may be extended to support one side of the fourth panel forming the side of the main body. A support frame may be provided, both ends of which are joined to a side cover forming one side of the machine room. The hinge reinforcement frame may be arranged between the front cover and the support frame. The side of the hinge reinforcement frame may be joined to the front cover and / or the support frame, or the first side and the second side of the hinge reinforcement frame may be joined to the front cover and the support frame, respectively.

[0023] An inner cover may be positioned between the front cover and the first frame portion. A boss portion may be formed to protrude from the inner cover to surround the first connecting member. The first connecting member may be penetrated through the hinge connecting portion and / or the front cover and connected to the boss portion.

[0024] According to an embodiment of the present invention, the following effects can be achieved.

[0025] First, in the support structure of the hinge that supports the door to be movable on the surface of the main body, the hinge joint is not coupled to the main body but to the machine room. Accordingly, even if the main body is composed of a vacuum insulator, the hinge joint is not coupled to the main body, so there is no need to form a joint hole penetrating the main body. There is no concern about cold air leakage and / or vacuum leakage due to the formation of a hole in the vacuum insulator.

[0026] Second, the hinge reinforcement frame may include at least one of the first to fourth frame sections. The first frame section is coupled to the front cover of the machine room to which the hinge joint is coupled. The first frame section is coupled to the front cover of the machine room to increase the thickness of the front cover on which the hinge joint is supported, thereby improving the supporting strength of the hinge joint.

[0027] Third, the second frame portion can increase the strength of the hinge reinforcement frame by being formed to be bent from a portion (e.g., the upper portion) of the first frame portion. In addition, the second frame portion can support the hinge axis coupled to the door more stably by being coupled to a surface of the machine room spaced in the opposite direction of the hinge axis on which the door load is applied, for example, an extension of the first panel or a surface of the fourth panel, based on the front cover or inner cover supporting the hinge joint.

[0028] Fourth, the third frame portion may be coupled to the first portion of a support frame that is coupled to a portion of the side cover of the machine room. This allows the third frame portion to be coupled to a support frame spaced in the opposite direction of the hinge axis from the front cover or inner cover, thereby further securing the strength of the hinge joint.

[0029] Fifth, the fourth frame portion may be formed to be bent at the lower end of the first frame portion. The fourth frame portion is arranged in the opposite direction of the second frame portion with respect to the first joining hole of the first frame portion as the reference, so that the strength of the hinge reinforcing frame can be evenly reinforced with respect to the hinge joining portion as the reference.

[0030] Sixth, the first frame portion forms the surface of the hinge reinforcement frame. The second frame portion forms the surface of the hinge reinforcement frame. The third frame portion forms the surface of the hinge reinforcement frame. The fourth frame portion forms the surface of the hinge reinforcement frame. The hinge reinforcement frame can prevent sagging of the door by reinforcing the strength of the hinge.

[0031] Seventh, at least one of the first to fourth frame sections may be formed into a polygon or quadrangle with one side open. This facilitates the manufacture of the hinge-reinforced frame, and reduces material and / or manufacturing costs.

[0093] A machine room (110) may be installed in a part of the fourth panel (104). The fourth panel (104) may partition the storage room of the main body (100) and the machine room (110).

[0094] The vacuum insulation can form a part of at least one of the second panel (101), the third panel (102), the first panel (103), the fourth panel (104), and the door (108, 109). In the present embodiment, the vacuum insulation can be applied to each of the second panel (101), the third panel (102), the first panel (103), and the door (108, 109). At least one of the first, second, third, and fourth panels (104) can be composed of a non-vacuum insulation, or a combination of a non-vacuum insulation and a vacuum insulation. The fourth panel (104) can be composed of a non-vacuum insulation, or a combination of a non-vacuum insulation and a vacuum insulation. In the present embodiment, the fourth panel (104) is shown as being composed of a non-vacuum insulation.

[0095] For example, the fourth panel (104), which is a non-vacuum insulation body, may be composed of a panel cover (1041) forming the exterior of the panel and / or a polyurethane foam (1042) formed by foaming by injecting a polyurethane foam liquid into the interior of the panel cover (1041).

[0096] A storage room is formed inside the main body (100). The storage room includes a first storage room (105) and / or a second storage room (106). The second storage room (106) can be maintained at a preset first temperature, for example, -20°C. However, the present invention is not limited to the preset first temperature. The first storage room (105) can be maintained at a preset second temperature, for example, +5°C. However, the present invention is not limited to the preset second temperature.

[0097] In this embodiment, the first storage chamber (105) and / or the second storage chamber (106) are shown arranged on one side (e.g., upper side) and the other side (e.g., lower side) of the main body (100). However, the positions of the first storage chamber (105) and the second storage chamber (106) may be reversed.

[0098] The first storage room (105) and the second storage room (106) may be partitioned by a partition wall (107). The partition wall (107) extends in one direction (e.g., horizontally) between one of the first panels (1031) and the other of the first panels (1032). The partition wall (107) may be spaced apart from the third panel (102) and the fourth panel (104).

[0099] The partition wall (107) may be positioned between 1 / 3 and 2 / 3 of the height (vertical distance) between the fourth panel (104) and the third panel (102) in one direction (e.g., upward) from the fourth panel (104) when the height is divided into three equal parts. In the present embodiment, the partition wall (107) is shown positioned at approximately 1 / 3 of the height in one direction (e.g., upward) from the fourth panel (104).

[0100] The fourth panel (104) is positioned between the main body (100) and the machine room (110). The fourth panel (104) is configured to separate the storage room of the main body (100) and the machine room (110). The fourth panel (104) forms a surface of the main body (100). The fourth panel (104) may also form a surface of the machine room (110).

[0101] A support frame (114) may be coupled to a portion of the machine room (110) to support the fourth panel (104). The support frame (114) may be formed in the shape of a metal plate.

[0102] The support frame (114) can be coupled to the surface of the fourth panel (104). The support frame (114) extends between the first side cover and the second side cover (1132) of the machine room (110) to be described later. The support frame (114) can have a ㄷ-shaped cross-section shape to improve strength. One side (e.g., left end) of the support frame (114) can be coupled to the first side cover of the machine room (110) to be described later, and / or the other side (e.g., right end) of the support frame (114) can be coupled to the second side cover (1132) of the machine room (110) to be described later.

[0103] A plurality of support frames (114) may be provided. At least two support frames (114) are arranged spaced apart from each other in one direction of the fourth panel (104) and are coupled to the surface of the fourth panel (104). The support frame (114) includes a first support frame (115) and / or a second support frame.

[0104] The first support frame (115) is positioned so as to be spaced apart from one end (e.g., the front end) of the surface of the fourth panel (104) by a predetermined first interval. The second support frame is positioned so as to be spaced apart from the other end (e.g., the rear end) of the surface of the fourth panel (104) by a predetermined second interval.

[0105] The support frame (114) may include a first part (1151), a second part (1152), and / or a third part (1154).

[0106] The first part (1151) is positioned to face the surface of the fourth panel (104) and can be joined to the fourth panel (104). The second part (1152) is formed to protrude from a portion (e.g., the front end) of the first part (1151). The third part (1154) is formed to protrude from another portion (e.g., the rear end) of the first part (1151). The second part (1152) and the third part (1154) are positioned to face each other in one direction.

[0107] The door (108, 109) includes a first storage room door (108) and / or a second storage room door (109).

[0108] The first storage compartment door (108) can be movably installed on one side (e.g., upper side) of the main body (100) to open and close the first storage compartment (105). One side (e.g., left or right side) of the first storage compartment door (108) is movably connected to the main body (100) by a hinge (127, 128, 129). In this embodiment, one side (e.g., right side) of the first storage compartment door (108) is shown connected to the main body (100) by a hinge (127, 128, 129).

[0109] However, in the case where a plurality of main bodies (100) are arranged adjacent to each other in one direction, a first hinge may be installed on one side (e.g., right side) of one side (e.g., right side) of one main body (100), and / or one side (e.g., right side) of one side (e.g., right side) of the first storage door (108) may be coupled by the first hinge. A second hinge may be installed on the other side (e.g., left side) of the other side (e.g., left side) of the first storage door (108) may be coupled by the second hinge.

[0110] The second storage compartment door (109) can be installed movably or slidably on one side (e.g., the lower side) of the main body (100) to open and close the second storage compartment (106). In this embodiment, the second storage compartment door (109) is shown as being movably installed on the main body (100).

[0111] The hinge (129) includes a first hinge (127; upper hinge) installed in the third panel (102), a second hinge (128; middle hinge) installed in the partition wall (107), and / or a third hinge (129; lower hinge) installed in the machine room (110). Here, a detailed description of the third hinge (129) will be described later.

[0112] The first side and / or the second side of the first storage room door (108) are installed on the side of the main body (100) so as to be movable by the first hinge (127) and / or the second hinge (128).

[0113] The first side and / or the second side of the second storage room door (109) are installed on the side of the main body (100) so as to be movable by the second hinge (128) and / or the third hinge (129).

[0114] When the door is closed, the surface of the door and the surface of the main body (100) come into contact with each other. A gasket (118) is placed between the surface of the door and the surface of the main body (100). The gasket (118) may be made of an elastic material such as rubber. Through this, the gasket (118) can prevent cold air from leaking through the gap between the door and the main body (100).

[0115] The door (108, 109) may include vacuum insulation and / or non-vacuum insulation. A portion of the door may be composed of vacuum insulation, and another portion of the door (108, 109) may be composed of non-vacuum insulation.

[0116] For example, the surface of the door (108, 109) may be arranged toward one side (e.g., the outside) of the refrigerator and / or may be composed of a vacuum insulator. The surface of the door (108, 109) may be arranged toward the other side (e.g., the inside) of the refrigerator and / or may be composed of a non-vacuum insulator. A receiving groove (119) may be formed on the surface of the door (108, 109) that is a non-vacuum insulator to receive a gasket joint (1181) protruding from a gasket (118).

[0117] When the door (108, 109) is opened, the surface of the main body (100) can be exposed to the outside. A decoration (120) (Front Decoration) is placed on the surface of the main body (100). The decoration (120) can be formed of a plastic material. In this way, the decoration (120) can finish the surface of the main body (100) to make the appearance of the main body (100) more attractive. The decoration (120) is formed to wrap the surface of the fourth panel (104).

[0118] A hotline (121) may be further installed inside the deco (120). A hotline receiving portion (122) (1261) may be formed in the deco (120) (126).

[0119] The hot line (121) is placed between the deco (120) (126) and the surface of the fourth panel (104). The hot line (121) is accommodated in the hot line receiving portion (122). Accordingly, the deco (120) can surround the hot line (121) to block heat exchange between the cold air of the storage room and the hot line (121).

[0120] The hot line (121) is a refrigerant pipe through which refrigerant flows, and by receiving heat from the condenser and radiating heat, it can minimize condensation caused by the temperature difference between the outside air and the cold air.

[0121] The machine room (110) is configured to accommodate components such as a compressor, a condenser, and / or a cooling fan therein. The machine room (110) includes a front cover (111), a back cover, a side cover (113), and a bottom cover that form the exterior. The front cover (111), the back cover, the side cover (113), and the bottom cover are made of a metal material that can maintain sufficient strength to support the load of the refrigerator and are thick. For example, the cover of the machine room (110) has a thickness thicker than the plates (123, 124, 125) of the vacuum insulator.

[0122] The front cover (111) forms the surface of the machine room (110). The back cover forms the surface of the machine room (110). The front cover (111) and the back cover are each extended.

[0123] The side cover (113) forms the side of the machine room (110). The side cover (113) extends in one direction and connects the front cover (111) and the back cover. The side cover (113) includes a first side cover and a second side cover (1131).

[0124] The first side cover may form one side (e.g., the left side) of the machine room (110). The first side cover is coupled to the front cover (111) and / or the back cover, or a part (e.g., the front end) and / or another part (e.g., the rear end) of the first side cover is coupled to one side (e.g., the left end) of the front cover (111) and the back cover.

[0125] The second side cover (1131) can form the other side (e.g., right side) of the machine room (110). The second side cover (1131) is coupled to the front cover (111) and / or the back cover, or a part (e.g., front end) and / or another part (e.g., rear end) of the second side cover (1131) is coupled to the other side (e.g., right end) of the front cover (111) and / or the back cover.

[0126] The corners of the bottom cover are joined to the front cover (111), the back cover, the first and / or second side covers (1131).

[0127] A roller is movably installed at the first end and / or the second end of the bottom cover. Accordingly, the roller moves along the ground, making it easy to transport the refrigerator.

[0128] The second panel (101) of the main body (100) and the back cover of the machine room (110) can be aligned to form the same plane. The first panel (103) of the main body (100) and the side cover (113) of the machine room (110) can be aligned to form the same plane. The door and the front cover (111) of the machine room (110) can be aligned to form the same plane.

[0129] The compressor and / or condenser are installed on the surface of the bottom cover. The compressor and condenser may be spaced apart from each other in one direction.

[0130] At least one of the compressor and the condenser may be arranged to be spaced apart from the back cover by a first distance and / or spaced apart from the front cover (111) by a second distance. In this case, the first distance and the second distance may be different from each other.

[0131] A cooling fan may be positioned between the compressor and the condenser. The cooling fan is configured to provide power to the air. The cooling fan is configured to allow the outside air to flow in one direction. In this embodiment, the cooling fan is configured to allow the outside air to flow from the compressor through the cooling fan and into the condenser.

[0132] An intake port (1132) may be formed in the second side cover (1132). An exhaust port may be formed in the first side cover. The intake port (1132) and the compressor may be spaced apart in one direction and arranged to face each other. The condenser and the exhaust port may be spaced apart in one direction and arranged to face each other.

[0133] The intake port (1132) and exhaust port can be formed in the form of narrow and long through holes. The through holes are formed to penetrate the side cover (113) in one direction.

[0134] According to this, the cooling fan draws in outside air through the intake port (1132). The drawn-in air can cool the compressor by exchanging heat with the compressor as it passes through the compressor. The air passing through the compressor can cool the condenser by exchanging heat with the condenser via the cooling fan. Subsequently, the air passing through the condenser can be discharged to the outside through the exhaust port.

[0135] The vacuum insulator includes a first plate (123), a second plate (124), and / or a side plate (125) made of metal. As a result, the door may have improved insulation performance when it includes a vacuum insulator, but its weight may increase compared to the door of a foam-insulated refrigerator.

[0136] Among the first hinge (127), the second hinge (128), and the third hinge (129), the hinge (129) on which the door load acts the greatest may be the third hinge (129). Therefore, it is necessary to increase the support strength of the third hinge (129).

[0137] Unless otherwise specified in the following description, hinge (129) refers to a third hinge (129).

[0138] Since the hinge (129) causes problems of cold air leakage and / or vacuum leakage when coupled to a vacuum insulator, the hinge (129) needs to be coupled to the machine room (110) rather than to the main body (100) composed of a vacuum insulator. For example, the hinge (129) may be coupled to the front cover (111).

[0139] The hinge (129) may be configured to include a hinge joint (130), a hinge shaft (134), and / or a hinge connection (133). The hinge (129) is formed of a metal material to support the load of the door.

[0140] The hinge joint (130) is coupled to the front cover (111). The hinge joint (130) may be formed in a polygonal (e.g., approximately rectangular) plate shape. The length of the hinge joint (130) in the first direction (e.g., left-right direction) may be extended longer than the width of the hinge joint (130) in the second direction (e.g., up-down direction).

[0141] The hinge joint (130) is connected and coupled to the front cover (111). Coupling holes (1301, 1302) are formed to penetrate through the hinge joint (130) in one direction. The coupling holes (1301, 1302) are arranged to be spaced apart from each other in one direction of the hinge joint (130). The coupling holes (1301, 1302) include a first coupling hole (1301) arranged on one side of the hinge joint (130) and / or a second coupling hole (1301, 1302) (1302) arranged on the other side.

[0142] A boss portion (1311) may be formed to protrude in one direction (e.g., rearward) toward the internal space of the machine room (110) from the surface of the front cover (111) or the inner cover (131) described later. In this embodiment, the boss portion (1311) is shown to protrude from the inner cover (131). At least two boss portions (1311) may be arranged to be spaced apart from each other in one direction on the inner cover (131).

[0143] The boss portion (1311) may be formed in a cylindrical shape. A female screw portion (1312) may be formed to penetrate the boss portion (1311) in one direction. The female screw portion (1312) and the coupling holes (1301, 1302) are arranged to overlap each other.

[0144] The front cover (111) may further include an inner cover (131) to enhance the strength of the hinge (129). The inner cover (131) may be formed to be thicker than the thickness of the front cover (111). The front cover (111) may form the exterior of the machine room (110), and / or the inner cover (131) may form the surface of the machine room (110).

[0145] The front cover (111) and the inner cover (131) are arranged to overlap each other to form two layers. Through this, the front cover (111) and the inner cover (131) can secure support for the hinge (129) in two layers.

[0146] A through hole can be formed in one direction so that a connecting member (132a, 132b) to be described later can pass through the front cover (111).

[0147] The connecting members (132a, 132b) may be implemented with screws, etc. The connecting members (132a, 132b) may have a size sufficient in strength to support the load of the refrigerator and may be formed of a metal material. The connecting members (132a, 132b) may penetrate the connecting holes (1301, 1302)(1301, 1302) of the hinge connecting part (130), the through hole of the front cover (111), and / or the boss part (1311) of the inner cover (131) and be connected to the boss part (1311). Through this, the hinge connecting part (130) may be connected to the front cover (111) and the inner cover (131) by the connecting members (132a, 132b).

[0148] The coupling members (132a, 132b) include a first coupling member (132a) coupled through a first coupling hole (1301) and / or a second coupling member (132b) coupled through a second coupling hole (1301, 1302). The coupling members (132a, 132b) may be arranged spaced apart from each other in one direction.

[0149] The hinge connection (133) is formed to protrude from a part (e.g., the upper part) of the hinge connection (130) to one side (e.g., the lower part) of the second storage compartment door (109). The hinge connection (133) may be formed to be bent in one direction (e.g., vertically) from the hinge connection (130). The hinge connection (133) and the hinge connection (130) may form an L-shape.

[0150] A portion of the hinge connection portion (133) may be arranged to overlap with the second storage compartment door (109). The protruding length of the hinge connection portion (133) protruding from the hinge joint portion (130) toward one side (e.g., the lower side) of the second storage compartment door (109) does not exceed the second storage compartment door (109).

[0151] The hinge axis (134) is formed in a cylindrical shape. The hinge axis (134) is extended. The hinge axis (134) may be formed to protrude from the hinge connection portion (133) toward the second storage compartment door (109), or may be coupled to the hinge connection portion (133) through a through hole formed in a part (e.g., a front end) of the hinge connection portion (133). In the present embodiment, the hinge axis (134) is shown as being integrally formed to protrude from the hinge connection portion (133).

[0152] A hinge shaft receiving portion (135) is formed to be sunken in one side of the surface of the second storage room door (109). The hinge shaft (134) is received in the hinge shaft receiving portion (135). A bushing or a bearing may be installed between the hinge shaft receiving portion (135) and the hinge shaft (134). The bushing or bearing is coupled to the hinge shaft receiving portion (135) and / or the hinge shaft (134) so ​​as to surround the hinge shaft (134). The bushing or bearing supports the second storage room door (109) so that the second storage room door (109) can move with respect to the hinge shaft (134). The second storage room door (109) can be coupled to the hinge connection portion (133) so as to move about the hinge shaft (134).

[0153] The thickness of the hinge connection (133) and / or the hinge joint (130) may be formed thicker than the thickness of the front cover (111) and / or the inner cover (131) to improve the strength of the hinge (129). As another example, the thickness of the hinge connection (133) or the hinge joint (130) may be greater than or equal to the sum of the thicknesses of the front cover (111) and the inner cover (131).

[0154] To reinforce the support strength of the hinge (129), a hinge reinforcement frame (136) is coupled to the front cover (111). When the inner cover (131) is coupled to the front cover (111), the hinge reinforcement frame (136) can be coupled to the inner cover (131).

[0155] The hinge reinforcement frame (136) includes a first frame portion (1361). The first frame portion (1361) is formed in a polygonal (e.g., rectangular) plate shape. The first direction (e.g., up and down) length of the first frame portion (1361) may be extended longer than the second direction (e.g., left and right) width of the first frame portion (1361).

[0156] The width of the first frame portion (1361) can be formed to correspond to the left-right width of the hinge joint portion (130).

[0157] The first frame portion (1361) can be in close contact with the surface of the front cover (111) or the inner cover (131). In this embodiment, the first frame portion (1361) is shown in close contact with the inner cover (131).

[0158] The first frame portion (1361) includes first coupling holes (1362a, 1362b). The first coupling holes (1362a, 1362b) are formed to penetrate the first frame portion (1361) in one direction. The first coupling holes (1362a, 1362b) are formed to correspond to the coupling holes (1301, 1302). For example, the first coupling holes (1362a, 1362b) and / or the coupling holes (1301, 1302) may be formed as a closed curve (e.g., circular).

[0159] The first coupling holes (1362a, 1362b) are arranged concentrically with the coupling holes (1301, 1302) with an imaginary line passing through the center of the coupling holes (1301, 1302) of the hinge joint (130) in one direction as the center.

[0160] However, the diameter of the first coupling hole (1362a, 1362b) may be larger than or equal to the diameter of the coupling hole (1301, 1302). In the present embodiment, the diameter of the first coupling hole (1362a, 1362b) is shown to be larger than the diameter of the coupling hole (1301, 1302). The diameter of the female screw portion (1312) of the boss portion (1311) is formed to correspond to the diameter of the coupling hole (1301, 1302).

[0161] The outer circumferential diameter of the boss portion (1311) is larger than the diameter of the joining holes (1301, 1302). The thickness of the boss portion (1311) is formed between the outer circumferential surface and the inner circumferential surface of the boss portion (1311). The thickness of the boss portion (1311) may be greater than or equal to the thickness of the inner cover (131). In the present embodiment, the thickness of the boss portion (1311) is shown to be formed to be larger than the thickness of the inner cover (131).

[0162] The diameter of the first coupling hole (1362a, 1362b) is formed to correspond to the diameter of the outer surface of the boss portion (1311). The periphery of the first coupling hole (1362a, 1362b) is formed to surround the outer surface of the boss portion (1311) of the inner cover (131). The boss portion (1311) of the inner cover (131) can be inserted through the first coupling hole (1362a, 1362b) and coupled with the first frame portion (1361). Through this, the first frame portion (1361) forms three layers together with the inner cover (131) on the front cover (111), and the supporting strength of the hinge coupling portion (130) can be increased. The first frame portion (1361) can be restricted from moving in one direction (e.g., up and down) with respect to the boss portion (1311).

[0163] The first frame portion (1361) can be force-fitted to the boss portion (1311) through the first coupling hole (1362a, 1362b). Through this, the first frame portion (1361) can be restricted from moving in one direction along the boss portion (1311).

[0164] At least two first coupling holes (1362a, 1362b) are coupled to at least two boss portions (1311) spaced apart from each other in one direction, so that movement of the first frame portion (1361) can be restricted.

[0165] The support frame (114) includes a first connecting portion (116). The support frame (114) is configured to be connected to a portion of the first panel (103) by the first connecting portion (116). The first connecting portion (116) is provided at each end of the support frame (114).

[0166] The first connecting portion (116) extends from one end (e.g., left-right direction) of the support frame (114) toward one side (e.g., lower side) of the first panel (103).

[0167] A part (e.g., front end) of the first connecting portion (116) of the first support frame (115) is arranged adjacent to a part of the front cover (111), and / or another part (e.g., rear end) of the first connecting portion (116) of the first support frame (115) is arranged spaced apart in one direction from a part (e.g., front end) of the first connecting portion (116) of the second support frame.

[0168] A joining hole (1161) is formed in a part of the first joining portion (116) and / or another part, or a joining hole (1161) is formed in a part (e.g., front end) and / or another part (e.g., rear end) of the first joining portion (116). The joining hole (1161) is formed to penetrate the first joining portion (116), so that a joining member (132a, 132b), such as a screw, which will be described later, can penetrate the joining hole (1161).

[0169] The first panel (103) is composed of a vacuum insulator and includes a first plate (123), a second plate (124), and a side plate (125). A vacuum space (126) is formed between the first plate (123) and the second plate (124). A support is provided between the first plate (123) and the second plate (124). The support is configured to maintain the vacuum space (126).

[0170] The first plate (123) is positioned toward the storage compartment inside the refrigerator. The second plate (124) is positioned toward the exterior of the refrigerator. The side plate (125) is connected to the second plate (124) extending from the first plate (123) to form the side of the vacuum space (126).

[0171] The side plate (125) can be connected to the second plate (124) by sealing or welding, etc. A sealing line or welding line can be formed at the part where the side plate (125) and the second plate (124) are connected.

[0172] An extension portion (1241) is provided on a portion of the second plate (124). The extension portion (1241) is formed to be bent in one direction at the lower end of the second plate (124).

[0173] The first connecting portion (116) can be connected to the extension portion (1241) of the second plate (124) by a connecting member (132a, 132b) such as a screw penetrating the connecting hole (1153).

[0174] The second connecting portion (117) is formed to be bent in one direction (e.g., left and right) from the side of the first connecting portion (116). The second connecting portion (117) is positioned to face the side cover (113) of the machine room (110). A connecting hole (1153) is formed to penetrate the second connecting portion (117) in one direction, so that the second connecting portion (117) is connected to the side cover (113) by a connecting member (132a, 132b) such as a screw.

[0175] Through this, both ends of the support frame (114) can be joined to the first panel (103) by the first joining portion (116). It can be joined to and supported by the side cover (113) of the machine room (110) by the second joining portion (117).

[0176] The hinge reinforcement frame (136) may include a second frame portion (1363). The second frame portion (1363) may be connected to the first frame portion (1361) integrally or in a combined manner. The second frame portion (1363) may be formed to protrude in one direction (e.g., in the rearward direction) from a portion (e.g., the upper portion) of the first frame portion (1361). The first frame portion and the second frame portion (1363) are connected to each other in one direction (e.g., vertically).

[0177] The length in the first direction (e.g., left-right direction) of the second frame portion (1363) may be formed to be longer than or equal to the width in the second direction (e.g., front-to-rear direction) of the second frame portion (1363). In the present embodiment, the length in the first direction (e.g., left-to-right direction) of the second frame portion (1363) is shown to be formed to be longer than the width in the second direction (e.g., front-to-rear direction) of the second frame portion (1363).

[0178] The width in the second direction (e.g., front-to-rear direction) of the second frame portion (1363) may be formed to correspond to the gap between the front cover (111) or the inner cover (131) and the first support frame (115). In the present embodiment, the width in the second direction (e.g., front-to-rear direction) of the second frame portion (1363) is shown to be formed to correspond to the gap between the inner cover (131) and the first support frame (115). Through this, the second frame portion (1363) may connect the first frame portion (1361) and the third frame portion (1365) to be described later, and / or the first frame portion (1361) may be tightly coupled to the inner cover (131). The third frame portion (1365) may be tightly coupled to the second part (1152) of the first support frame (115).

[0179] A folded portion (112) is provided on a portion of the front cover (111). The folded portion (112) is formed to protrude from a portion (e.g., the upper portion) of the front cover (111) so as to cover a portion of the second frame portion (1363). The folded portion (112) may extend along a portion of the front cover (111). Through this, the folded portion (112) can enhance the strength of the front cover (111).

[0180] The bending portion (112) is arranged to overlap and / or be connected to the second frame portion (1363). Through this, the bending portion (112) and the second frame portion (1363) can support each other, thereby reinforcing the supporting strength of the hinge (129).

[0181] A second coupling hole (1364) may be formed in the second frame portion (1363). The second coupling hole (1364) may be positioned adjacent to a portion (e.g., the right end) of the second frame portion (1363). In the present embodiment, one second coupling hole (1364) may be provided, but the number of second coupling holes (1364) is not limited thereto.

[0182] The second coupling hole (1364) may be arranged to overlap with the coupling hole (1153) formed in a part (e.g., the front end) of the first coupling portion (116). Through this, a coupling member (132a, 132b) such as a screw may pass through the second coupling hole (1364), the coupling hole (1153) of the first coupling portion (116) and / or the coupling hole (1153) of the extension portion (1241) to be coupled to the second frame portion (1363), the first coupling portion (116) and / or the extension portion (1241). The second frame portion (1363), the first coupling portion (116) and / or the extension portion (1241) may be tightly coupled to other components by the coupling members (132a, 132b). Through this, two or more of the second frame portion (1363), the support frame (114), and the first panel (103) can be combined with each other. Therefore, two or more of the second frame portion (1363), the support frame (114), and the first panel (103) are arranged to overlap each other, thereby increasing the thickness, thereby not only improving the support strength of the hinge (129), but also increasing the support strength of the first panel (103).

[0183] As another example, the second frame portion (1363) may be coupled with a hinge reinforcing plate (137), or may be coupled with a hinge reinforcing plate (137) accommodated within the fourth panel (104). The hinge reinforcing plate (137) may be made of a metal material. A coupling groove (1371) may be formed in a portion (e.g., a front end) of the hinge reinforcing plate (137). A coupling member (132a, 132b), such as a screw, may pass through the second coupling hole (1364) of the second frame portion (1363) and be coupled to the coupling groove (1371) of the hinge reinforcing plate (137). Through this, the hinge reinforcing plate (137) may be coupled with the second frame portion (1363), thereby increasing the support strength of the hinge joint portion (130).

[0184] The hinge reinforcement frame (136) may include a third frame portion (1365). The third frame portion (1365) may be integrally connected to the second frame portion (1363). The third frame portion (1365) is formed to protrude from a portion (e.g., the rear end) of the second frame portion (1363).

[0185] The first direction (e.g., left-right direction) length of the third frame portion (1365) is formed to correspond to the first direction (e.g., left-right direction) width of the second frame portion (1363). The second direction (e.g., up-down) width of the third frame portion (1365) may be formed to be shorter than the second direction (e.g., up-down) length of the first frame portion (1361).

[0186] The third frame part (1365) can be spaced apart from the first frame part (1361) to face each other at a preset interval.

[0187] The third frame portion (1365) is arranged in close contact with the second portion (1152) of the first support frame (115) in one direction. Third coupling holes (1366a, 1366b) are formed to penetrate through the third frame portion (1365) in one direction. At least two third coupling holes (1366a, 1366b) are arranged to be spaced apart from each other in one direction in the third frame portion (1365).

[0188] At least two third coupling holes (1366a, 1366b) can be spaced apart from the first coupling holes (1362a, 1362b) so as to face each other in one direction.

[0189] A joining hole (1153) may be formed to penetrate in one direction in the second part (1152) of the first support frame (115). The joining hole (1153) of the second part (1152) may be formed to correspond to the third joining hole (1366a, 1366b) of the third frame part (1365). A joining member (1367a, 1367b), such as a screw, may pass through the third joining hole (1366a, 1366b) of the third frame part (1365) and / or the joining hole (1153) of the second part (1152) of the support frame (114) to be joined to the third frame part (1365) and / or the support frame (114). Through this, the third frame part (1365) and the support frame (114) can be firmly connected to each other through the third connecting hole (1366a, 1366b) and / or the connecting hole (1153) of the second part (1152).

[0190] The third coupling hole (1366a, 1366b) of the third frame part (1365) may be positioned higher than the first coupling hole (1362a, 1362b) of the first frame part (1361). This is because the coupling position of the support frame (114) coupled to the side cover (113) of the machine room (110) is higher than the coupling position of the hinge coupling part (130) coupled to the front cover (111) of the machine room (110).

[0191] It is preferable that the support frame (114) be installed in a part of the machine room (110) to support the fourth panel (104) and / or the hinge reinforcement frame (136).

[0192] The hinge reinforcement frame (136) may include a fourth frame portion (1368). The fourth frame portion (1368) is formed to protrude from a portion (e.g., the lower portion) of the first frame portion (1361). The length of the fourth frame portion (1368) in the first direction (e.g., the left-right direction) is formed to be longer than the width of the fourth frame portion (1368) in the second direction (e.g., the front-rear direction).

[0193] The fourth frame portion (1368) may be positioned facing and / or spaced apart from the second frame portion (1363). The width in the first direction (e.g., front-to-rear direction) of the fourth frame portion (1368) may be formed to be smaller than or equal to the width in the first direction (e.g., front-to-rear direction) of the second frame portion (1363). In the present embodiment, the width in the first direction (e.g., front-to-rear direction) of the fourth frame portion (1368) is shown to be formed to be smaller than the width in the first direction (e.g., front-to-rear direction) of the second frame portion (1363).

[0194] The hinge reinforcement frame (136) may be configured to include at least one of the first frame portion (1361), the second frame portion (1362), the third frame portion (1363), and the fourth frame portion (1368) described above. The first frame portion (1361), the second frame portion (1362), the third frame portion (1363), and / or the fourth frame portion (1368) may be integrally formed in a polygonal shape (e.g., a square). However, the hinge reinforcement frame (136) may be formed in a polygonal shape (e.g., a square) with one side open rather than a closed loop shape. The first direction (e.g., up and down) width of the third frame portion (1365) may be shorter than the first direction (e.g., up and down) length of the first frame portion (1361), and / or the first direction (e.g., front-to-rear) width of the fourth frame portion (1368) may be shorter than the first direction (e.g., front-to-rear) width of the second frame portion (1363). As a result, the third frame portion (1365) and the fourth frame portion (1368) are not connected to each other and are spaced apart from each other.

[0195] Through this, the hinge reinforcement frame (136) formed in a polygonal (e.g., square) structure with one side open can form the first frame portion (1361), the second frame portion (1362), the third frame portion (1363) and / or the fourth frame portion (1368) by bending a rectangular metal plate through press processing. The hinge reinforcement frame (136) can form the first coupling holes (1362a, 1362b) to the third coupling holes (1366a, 1366b) of the first frame portion (1361) to the third frame portion (1365) respectively through press processing. According to this, the hinge reinforcement frame (136) is easy to manufacture while securing the support strength of the hinge (129). The material cost and / or manufacturing cost of the hinge reinforcement frame (136) can be reduced.

[0196] Accordingly, according to the present invention, in the support structure of the hinge (129) that supports the door to be movable on the surface of the main body (100), the hinge joint (130) is coupled to the machine room (110). Through this, even if the main body (100) is composed of a vacuum insulator, there is no need for the hinge joint (130) to form a joint hole (1301, 1302) penetrating the main body (100). There is no concern about cold air leakage and / or vacuum leakage due to the formation of a hole in the vacuum insulator.

[0197] The hinge reinforcement frame (136) may include at least one of the first frame portion (1361) to the fourth frame portion (1368). The first frame portion (1361) is coupled to the front cover (111) of the machine room (110) to which the hinge joint portion (130) is coupled. The first frame portion (1361) is coupled to the front cover (111) of the machine room (110) to increase the thickness of the front cover (111) on which the hinge joint portion (130) is supported, thereby improving the supporting strength of the hinge joint portion (130).

[0198] The second frame portion (1363) can increase the strength of the hinge reinforcing frame (136) by being formed to be bent from a portion (e.g., the upper portion) of the first frame portion (1361). In addition, the second frame portion (1363) can be coupled to a surface of the machine room (110) spaced in the opposite direction of the hinge axis (134) on which the load of the door is applied, based on the front cover (111) or inner cover (131) supporting the hinge joint (130), for example, the extension (1241) of the first panel (103) or the surface of the fourth panel (104), thereby more stably supporting the hinge axis (134) coupled to the door.

[0199] The third frame portion (1365) can be coupled to the first part (1151) of the support frame (114) that is coupled to a part of the side cover (113) of the machine room (110). Through this, the third frame portion (1365) can be coupled to the support frame (114) that is spaced apart from the hinge axis (134) in the opposite direction from the front cover (111) or the inner cover (131), thereby ensuring stable strength of the hinge joint portion (130).

[0200] The fourth frame portion (1368) may be formed to be bent at one end or the lower end of the first frame portion (1361). The fourth frame portion (1368) is arranged in the opposite direction of the second frame portion (1363) with respect to the first coupling hole (1362a, 1362b) of the first frame portion (1361), thereby enabling the strength of the hinge reinforcing frame (136) to be evenly reinforced with respect to the hinge coupling portion (130).

[0201] In addition, the first frame portion (1361) forms a surface of the hinge reinforcement frame (136). The second frame portion (1363) forms a surface of the hinge reinforcement frame (136). The third frame portion (1365) forms a surface of the hinge reinforcement frame (136). The fourth frame portion (1368) forms a surface of the hinge reinforcement frame (136).

[0202] Furthermore, the first, second, and third frame sections (1361, 1362, and 1363) and / or the fourth frame section (1368) may form a polygon or a quadrangle with one side open. This facilitates the manufacture of the hinge reinforcement frame (136), and reduces material costs and / or manufacturing costs.
