Description

refrigerator

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

[0002] First, there is the applicant's registered patent No. 10-0343719 (Patent Document 1). According to this patent, a vacuum adiabatic panel is manufactured, embedded in the wall of a refrigerator, and the exterior of the vacuum adiabatic panel is finished with a separate molded Styrofoam material. This method eliminates the need for foaming and improves insulation performance. However, this method has the drawback of increasing costs and complicating the manufacturing process.

[0003] As another example, there have been attempts to fabricate the entire refrigerator wall as a single piece of insulation. For example, U.S. Patent Publication No. US2040226956A1 (Patent Document 2) discloses a method for providing vacuum-insulated refrigerator structures. However, achieving a practical level of insulation by providing sufficient vacuum in the refrigerator walls is challenging. Specifically, this method suffers from several problems, including the difficulty in preventing heat transfer at the contact points between the outer and inner cases, which have different temperatures, the difficulty in maintaining a stable vacuum, and the difficulty in preventing deformation of the case due to negative vacuum pressure.

[0004] In addition, Japanese Patent Application Laid-Open No. 2011-247534 (Patent Document 3) discloses an insulation box that simplifies the bonding work and improves productivity when installing and preparing multiple vacuum insulation panels.

[0005] Patent Document 3 discloses an insulating case of a refrigerator comprising an inner case and an outer case and a plurality of vacuum insulation panels provided between them, and forming a plurality of wall sections of a refrigerator body, wherein the inner case is formed by combining a plurality of inner case partitions into which the entire inner case is divided, and at the same time, a plurality of vacuum insulation panels are formed in a shape corresponding to each inner case partition, and each of these vacuum insulation panels and each of the inner case partitions is installed.

[0006] In a refrigerator in which a portion of the body wall of the refrigerator includes a vacuum insulator, development of a refrigerator having a structure capable of improving the overall efficiency of the refrigerant compression cycle is required.

[0107] The insulator (10) of the present invention can be applied to a refrigerator (1). The refrigerator (1) may include a main body (2) provided with a cavity (9) capable of storing stored items, and a door (3) provided to open and close the main body (2). A cold source for supplying cold air (Cold) to the cavity (9) may be provided. For example, the cold source may be an evaporator (7) that evaporates a refrigerant to remove heat. The refrigerator may include a compressor (4) that compresses the refrigerant. The refrigerator may include a condenser (5) that condenses the compressed refrigerant. The condenser (5) may be connected to an expander (6) that expands the condensed refrigerant.

[0108] A refrigerator according to the present invention includes a main body (100) and a door (109, 110).

[0109] The main body (100) can form the exterior of the refrigerator. The main body (100) can include at least one panel. The main body (100) can include a first panel (101), a second panel (102), a third panel (103), a fourth panel (104), and / or a block (105).

[0110] The first panel (101) and the second panel (102) may be two sides of a refrigerator that are arranged parallel to each other. For example, the first panel (101) and the second panel (102) may be arranged so that the -y direction and the +y direction are normal lines, respectively.

[0111] The third panel (103) forms one side of the refrigerator (100). The third panel (103) may be arranged so that the -x direction is the normal, for example. The fourth panel (104) forms the other side of the refrigerator. The fourth panel (104) may be arranged so that the +z direction is the normal, for example.

[0112] The block (105) can define a surface that is arranged parallel to the fourth panel (104). For example, the block (105) can be arranged so that the -z direction is the normal.

[0113] A machine room (106) may be provided on one side of the block (105).

[0114] At least one or a portion of at least one of the first panel (101), the second panel (102), the third panel (103), the fourth panel (104) and the block (105) may be formed of a vacuum insulator.

[0115] For example, the first panel (101), the second panel (102), the third panel (103), and / or the fourth panel (104) may be formed of a vacuum insulator. The block (105) may be formed of a non-vacuum insulator.

[0116] The cycle piping may include, for example, a penetration member (122) and capillaries (1151, 1152). The cycle piping may be a liquid-gas heat exchanger.

[0117] The penetration part (122) (Suction Line Heat Exchanger; SLHX) can be formed as a tube that is connected between the evaporator (133) and the compressor (113) and allows the refrigerant to flow.

[0118] The through-hole component (122) can allow the low-temperature gaseous refrigerant passing through the evaporator (133) to flow to the compressor. At least one pair of through-hole components (122) can be provided.

[0119] Capillaries (1151, 1152) can be connected to one side and the other side of the capillaries (1151, 1152) in one direction and the other direction with the tube (123) therebetween. For example, the capillaries (1151, 1152) can be connected to both sides of the tube (123) by sealing or welding. The tube (123) and the capillaries (1151, 1152) can be formed in the form of long pipes. This allows the bending operation of the tube (123) to be performed smoothly.

[0120] Capillaries (1151, 1152) can implement an expander (115). Some of the expanders (115) implemented with capillaries (1151, 1152) are placed inside the machine room (106).

[0121] The expander (115) may be disposed between at least one of the walls within the machine room (106) and the duct. The expander (115) may be disposed between the side wall within the machine room (106) and the duct. The expander (115) may be provided as a capillary tube (1151, 1152). The capillary tubes (1151, 1152) are formed in the shape of a circular tube with a thin diameter. Through this, the capillary tubes (1151, 1152) can expand the refrigerant. The capillary tubes (1151, 1152) may be composed of at least two. Through this, the capillary tubes (1151, 1152) can increase the heat exchange efficiency.

[0122] One side of the capillary (1151, 1152) may be connected to the inside of the machine room (106). For example, it may be placed adjacent to one side cover within the machine room (106).

[0123] The refrigerant expanded in the capillary tube (1151, 1152) can be delivered to the evaporator (133). The through-hole component (122) is configured to enable the refrigerant evaporated in the evaporator (133) to be delivered to the compressor (113).

[0124] The penetrating part (122) may include a pipe (123), a first withdrawal portion (126) and / or a second withdrawal portion (127).

[0125] The tube (123) may be provided inside a panel on one side of the main body. The panel on one side of the main body may be a third panel (103) arranged in the -z direction. That is, the tube (123) may be arranged in the vacuum space (15) of the third panel (103).

[0126] Optionally, the tube (123) may be inserted into a panel on one side of the main body. The panel on one side of the main body may be, for example, a third panel (103).

[0127] For example, the pipe (123) may include a plurality of straight pipe sections and curved pipe sections connecting the straight pipe sections. FIG. 7a illustrates first to third straight pipe sections (123a, 123b, 123c) and first and / or second curved pipe sections (123d, 123e) provided therebetween. The pipe (123) is shown as having an example of having a shape roughly resembling an inverted "7". However, it is not necessarily limited to this configuration or shape. That is, the pipe (123) may include a different number of straight pipe sections and / or curved pipe sections than in FIGS. 7a and 7b, or may have various shapes such as a zigzag shape or an S shape.

[0128] The pipe (123) may have one side joined to a first communication hole formed in advance in the first plate (11) and / or the other side of the pipe (123) may be joined to a second communication hole (not shown) formed in advance in the first plate (11). The first communication hole may be a hole communicating with the first withdrawal portion (126), or the second communication hole may be a hole communicating with the second withdrawal portion (127). The first communication hole and the second communication hole may be spaced apart from each other in the first plate (11). The method by which both sides of the pipe (123) are joined to at least one of the first plate (11) and the second plate (12) may be welding. Both sides of the pipe (123) may also be joined only to the first plate (11). Optionally, one side of the pipe (123) may be coupled to the first plate (11) and / or the other side may be coupled to the second plate (12).

[0129] The relationship between the tube (123) and the surrounding components within the vacuum space (15) will be described later.

[0130] The first withdrawal portion (126) may be provided on one side of the pipe (123). For example, the first withdrawal portion (126) may be provided on the first straight pipe portion of the pipe (123). The first withdrawal portion (126) may be configured to transfer the refrigerant that has passed through the evaporator (133) to the pipe (123).

[0131] The first withdrawal portion (126) may have a portion arranged in a direction intersecting the panel on one side of the main body. For example, the first withdrawal portion (126) may have a first portion extending in a direction perpendicular to the panel on one side of the main body (+x direction).

[0132] The first withdrawal portion (126) may further have a portion extending between the first portion and the outlet of the evaporator (133).

[0133] Optionally, the first withdrawal portion (126) may further have a portion that is bent multiple times from the first portion. FIG. 7A illustrates an example in which the first withdrawal portion (126) includes a second portion that is bent in one direction from one side of the first portion, a third portion that is bent in the other direction intersecting with the one direction from one side of the second portion, and a fourth portion that extends parallel to the second portion from one side of the third portion. The first withdrawal portion (126) may have at least one pair. In the case of a double pipe, it may have a structure in which it is drawn out in a single, interconnected form.

[0134] The third panel (103) may be provided with a pull-out joint (161, 163). The pull-out joint (161, 163) may be arranged on one surface of the third panel (103). One surface of the third panel (103) may be the exterior of the vacuum space (15) or one surface of a storage room. The storage room may be a space formed by at least one panel and in which an item is stored. One surface of the third panel (103) may be one surface of the first plate (11) or one surface of a wall formed by at least a portion of the first plate (11). The pull-out joint (161, 163) may be a plate shape having a predetermined width. The first plate (11) is formed of a thin sheet metal, so there is a risk of breakage during joining, making it difficult to join the tube (123) or the capillary tube (1151, 1152). Therefore, through the withdrawal joint (161, 163), the tube (123) or the capillary tube (1151, 1152) can secure joining strength or support strength and / or be easily and firmly joined.

[0135] The withdrawal joint (161, 163) may be provided with a withdrawal hole for receiving the first and / or second withdrawal parts (126, 127) and / or a capillary hole for receiving the capillary tube (1151, 1152). An example in which the first and second withdrawal parts (126, 127) are installed in the withdrawal hole and / or the capillary tube (1151, 1152) is installed in the capillary hole is illustrated in Fig. 8c and the like.

[0136] The withdrawal coupling unit (161, 163) may include a first withdrawal coupling unit (161) to which one side of the first withdrawal unit (126) is connected and / or a second withdrawal coupling unit (163) to which one side of the second withdrawal unit (127) is connected.

[0137] In the part where at least one of the first and second withdrawal parts (126, 127) and the capillary tube (1151, 1152) is installed in the withdrawal joint (161, 163), a connecting support tube may be provided to support at least one side of the first and second withdrawal parts (126, 127) and the capillary tube (1151, 1152) so as to prevent at least one of the first and second withdrawal parts (126, 127) and the capillary tube (1151, 1152) from being damaged. In the part where the first and second withdrawal parts (126, 127) and the capillary tubes (1151, 1152) are installed in the withdrawal joint (161, 163), a connecting support tube may be provided to support the first and second withdrawal parts (126, 127) and the capillary tubes (1151, 1152) by surrounding one side thereof so as to prevent the first and second withdrawal parts (126, 127) and the capillary tubes (1151, 1152) from being damaged.

[0138] The pipe (123) is embedded in the third panel (103) (-x direction, for example, the rear). The penetrating part (122) can penetrate the first plate (11) in a direction intersecting the surface of the third panel (103) for connection with the high-temperature evaporator (133). Since the first plate (11) is made of a thin sheet, the fitting for pipe connection cannot be directly sealed or welded. For this purpose, the first draw-out part (126) can be sealed or welded to a draw-out joint part (161) of a certain thickness. The draw-out joint part (161) can be sealed or welded to the first plate (11).

[0139] In order to withdraw the pipe to the machine room (106), the pipe fitting must be sealed or welded through the extraction joint (161, 163) that penetrates one side or side of the third panel (103) (for example, one side or side of the first plate (11)). However, the one side or side of the third panel (103) has a narrow space, making sealing or welding impossible. To solve this problem, the pipe (123) is withdrawn in a direction (for example, vertically) intersecting the third panel (103) in order to withdraw the pipe to the machine room (106).

[0140] The second withdrawal portion (127) may be provided on the opposite side of one side of the pipe (123). For example, the second withdrawal portion (127) may be provided on the third straight pipe portion (123c) of the pipe (123). The first withdrawal portion (126) and the second withdrawal portion (127) may be provided on both sides of the pipe (123). The second withdrawal portion (127) may be arranged at a lower height than the first withdrawal portion (126).

[0141] The second withdrawal section (127) may be configured to transfer the refrigerant passing through the pipe (123) to the compressor. The second withdrawal section (127) may extend from the third straight pipe section (123c) toward the inlet of the compressor.

[0142] The second withdrawal portion (127) may have a portion extending in a direction intersecting the panel on one side of the main body. For example, the second withdrawal portion (127) may have a fifth portion (127a) extending in a direction perpendicular to the panel on one side of the main body (+x direction). The second withdrawal portion (127) may have a sixth portion (127b) extending from the fifth portion (127a) so as to be further bent in a direction intersecting therewith. As illustrated in Fig. 7a, the fifth portion (127a) may extend in the +x direction. The sixth portion (127b) may extend in the -z direction.

[0143] In the second outlet (127), a high-temperature refrigerant at a temperature almost similar to the outside temperature flows, so it is preferable that the second outlet (127) have a structure that is advantageous for insulation.

[0144] The second withdrawal portion (127) may be, at least in part, insulated by the block (105). For example, the sixth portion of the second withdrawal portion (127) may be accommodated in a through hole of the block (105).

[0145] The second withdrawal section (127) may have at least one pair. In the case of a double pipe, it may have a structure in which they are withdrawn in a single form that is connected to each other.

[0146] The block (105) may be formed of a non-vacuum insulator. The block (105) may be formed by filling a PU foam liquid into the inside of the block (105) cover, which is an example of a non-vacuum insulator, and then foaming the same. The block (105) may include a surface facing the machine room (106) on one side or may include a bottom surface (1051). The block (105) may include a surface facing at least one of the first panel and the second panel or may include side walls (1052, 1053). The block (105) may include a surface facing the third panel (103). The block (105) may be provided with an evaporator mounting portion (1054) on which the evaporator (133) is placed. The second withdrawal portion (127) may be formed on one side or the bottom surface of the block (105). A through hole (1051a) having a portion for receiving a second withdrawal portion (127) may be provided on one side or the bottom surface of the block (105). The second withdrawal portion (127) may be arranged to be insulated from the block. At least a portion of the second withdrawal portion (127) may be insulated by the block (105), so that heat exchange between the second withdrawal portion (127), which is relatively high temperature, and the interior of the furnace can be minimized, thereby improving insulation performance. A through hole (1051b) for receiving a capillary (1151, 1152) for insulation may be provided on one side or the bottom surface of the block (105).

[0147] Optionally, referring to FIG. 9d, the second withdrawal portion (127) may be formed toward the outer side. When the second withdrawal portion (127) is formed toward the outer side, the second withdrawal portion (127) may be coupled to the second plate (12). When the second withdrawal portion (127) is formed toward the outer side, the pipe (123) may be coupled to the first plate on one side and / or coupled to the second plate on the other side. When the second withdrawal portion (127) is formed toward the outer side, a cover portion (12a) may be provided that covers the second withdrawal portion (127) disposed toward the outer side. When the second withdrawal part (127) is formed toward the outer side, a passage guiding the second withdrawal part (127) so that it can be connected to the machine room (106) may be provided in the machine room (106). When the second withdrawal part (127) is formed toward the outer side, the second withdrawal part (127) through which relatively high-temperature refrigerant flows is arranged toward the outer side, so that the insulation performance at the inner side can be improved.

[0148] Optionally, a recessed portion (132) may be formed on one surface of the evaporator mounting portion (1054). The recessed portion (132) is formed to be sunken from one side to the other in the Z-axis direction. The recessed portion (132) may be formed to be inclined. A first through-hole portion (131) may be formed in the center of the recessed portion (132). The first through-hole portion (131) is configured to accommodate a portion of a drain pipe through which defrost water flows. The first through-hole portion (131) is formed to penetrate at least one of the walls of the block (105) or is formed to penetrate a side wall (1053) of the block (105). The first through-hole portion (131) is formed to penetrate at least one of the walls of the block (105) or is formed to penetrate in the Z-axis direction.

[0149] One side of the first through-hole (131) is connected to a drain pipe formed in the evaporator (133). The other side of the first through-hole (131) is connected to a drain (118) of the machine room (106).

[0150] Optionally, in the present invention, the through-hole (122) may be spaced apart from the drain (118) by a predetermined distance. The closer the distance between the through-hole (122) and the drain (118), the more advantageous it may be for preventing freezing. The further the distance between the through-hole (122) and the drain (118), the less effective the freezing may be. Therefore, it is preferable that the through-hole (122) and the drain (118) be spaced apart appropriately.

[0151] In the present invention, the third panel (103) formed of a vacuum insulator may include a first plate (11) and / or a second plate (12).

[0152] The third panel (103) may include a vacuum space (15) provided between the first plate (11) and the second plate (12).

[0153] Optionally, the third panel (103) may include a third plate (13). The third plate (13) may reduce deformation, sinking, or collapse of the wall forming the insulation (10) toward the inside of the vacuum space (15).

[0154] The wall forming the insulation (10) may include a first plate (11) and a second plate (12). A third plate (13) may be placed on at least one of the first plate (11) and the second plate (12).

[0155] The third plate (13) may be placed on a thinner portion of the first plate (11) and the second plate (12). The third plate (13) may be placed on a weaker portion of the first plate (11) and the second plate (12).

[0156] The third plate (13) may be placed on at least one side among the inner and outer sides of the vacuum space (15). In the present invention, an example in which it is placed on the inner side of the vacuum space (15) is mainly described.

[0157] Although not shown in the present invention, the third plate (13) may be formed to have a cut portion (not shown) in which one side is cut.

[0158] The third plate (13) may be cut from one side of the insulator (10). The third plate (13) may be cut from one side at a portion where a non-vacuum insulator is installed to improve insulation on the side of the first plate (11) or at a portion where the insulators (10) are joined to each other. The cut portion of the third plate (13) may be spaced apart from the non-vacuum insulator.

[0159] Referring to FIG. 8d, optionally, the third plate (13) may have grid-shaped ribs (13b, 13c, 13d).

[0160] The third plate (13) is arranged on the supporter (19). The third plate (13) may be arranged to overlap the block (105) on one side where the grid-shaped ribs (13b, 13c, 13d) are provided. The non-vacuum insulation body may have a portion that does not overlap with the plate portion (13a) of the third plate (13) or is spaced apart from it. The non-vacuum insulation body may be understood as a configuration that is arranged on the side of at least one of the first and second plates (11, 12) or between the panels that are connected to each other to improve insulation. The non-vacuum insulation body may be understood as a configuration that is arranged on the side of the first and second plates (11, 12) or between the panels that are connected to each other to improve insulation.

[0161] The penetrating part (122) may include a tube (123) arranged inside the vacuum space (15). The tube (123) may be provided with a portion spaced apart from one side of the third plate (13).

[0162] The pipe (123) may have a portion positioned between one of the first and second plates (11, 12) and the third plate (13).

[0163] The pipe (123) may not overlap with the third plate (13) in the thickness direction of the vacuum space (15).

[0164] The third plate (13) may be formed in a plate shape, formed in a grid shape, or include a plate-shaped portion and a grid-shaped portion.

[0165] The penetrating part (122) may have a portion penetrating the plate-shaped portion of the third plate (13), or may be positioned so as not to overlap with the grid-shaped portion of the third plate (13).

[0166] Optionally, the pipe (123) may be formed at a position where at least one of the first and second withdrawal portions (126, 127) does not overlap with the grid-shaped ribs (13b, 13c, 13d) of the third plate (13).

[0167] The first withdrawal portion (126) can be positioned at a position where a cut portion of the third plate (13) is formed so as to be spaced apart from the third plate (13).

[0168] Optionally, the tube (123) may be placed outside the third plate (13).

[0169] Optionally, the pipe (123) may not overlap with the third plate (13) in the thickness direction.

[0170] Optionally, the pipe (123) may be spaced apart from the third plate (13) in the thickness direction.

[0171] By having a structure in which the pipe (123) is spaced apart from the third plate (13) without overlapping it, heat bridges can be reduced, thereby improving insulation performance.

[0172] The pipe (123) can be arranged closer to the second plate (12) than to the first plate (11). As a result, in forming a curved pipe section (123d, 123e) having a predetermined R, a structure can be formed that is advantageous for bending toward the first plate (11).

[0173] For example, the pipe (123) can have a first withdrawal portion (126) that penetrates the third plate (13).

[0174] Optionally, the refrigerator of the present invention may include a supporter (19).

[0175] For example, the third panel (103) may include a supporter (19). The supporter (19) may include a plurality of bars (20).
