Description

Technical Field

[0001] The present invention relates to a refrigerator, and in particular to a refrigerator comprising a structure for fixing a heat dissipation pipe. Background Art

[0002] In a refrigerator, condensation may occur on the surface of the refrigerator due to the difference between the temperature inside the refrigerator and the outside air temperature. In order to prevent such condensation, a heat dissipation pipe is provided in the refrigerator, and the heat dissipation pipe is a pipe in which a high-temperature refrigerant flows.

[0003] Such a heat dissipation duct can appropriately prevent the occurrence of condensation by appropriately contacting with other components. For example, Patent Document 1 discloses an invention for fixing a heat dissipation duct to the above-mentioned other components.

[0006] Patent Document 1: Japanese Patent Application Laid-Open No. 8-313142. Summary of the Invention

[0007] [Problems to be solved by the invention]

[0008] Patent Document 1 discloses an inventive solution for securing a heat dissipation duct to a front plate mounted on the front portion of a partition wall. This document describes an inventive solution in which the front plate and heat dissipation duct are pre-secured using other components, and then the front plate secured to the heat dissipation duct is secured to the front portion of the partition wall.

[0009] This invention presents the following problems: The front panel and other components must be secured together using methods such as welding. Furthermore, even when no other components are used, the heat dissipation pipe must be secured to the front panel during assembly, which significantly reduces assembly workability. However, if the heat dissipation pipe is not securely secured in this manner, it may not be in proper contact with the other components, resulting in reduced heat transfer efficiency.

[0010] Therefore, an object of the invention according to the present disclosure is to provide a refrigerator having a shape that allows a heat dissipation duct to be easily and appropriately fixed at a predetermined position, thereby improving the assembly workability of the heat dissipation duct and enhancing the heat transfer efficiency to the partition plate.

[0011] [Solutions to solve the problem]

[0012] The refrigerator involved in the present invention is characterized in that it includes: a refrigerator body; a heat dissipation duct connected to the outlet side of the compressor; a first storage box and a second storage box accommodated in the refrigerator body, the first storage box having an opening on the front surface, and the second storage box being located below the first storage box and having an opening on the front surface; two duct fixing members installed in a manner extending in the left-right direction to each of the front lower part of the first storage box and the front upper part of the second storage box; and a partition plate provided between the first storage box and the second storage box with respect to the up-down direction and in front of the duct fixing member; the two heat dissipation ducts are arranged in the up-down direction, extend respectively in the left-right direction and are installed on the duct fixing member; the partition plate is between the duct fixing members and is installed to abut against the heat dissipation duct.

[0013] According to the present invention, since the heat dissipation pipe disposed between the first and second storage boxes can be mounted on the pipe fixing member, the heat dissipation pipe can be easily positioned in a predetermined position and precisely contacted with the partition plate. This improves the efficiency of heat transfer from the heat dissipation pipe to the partition plate, thereby improving power consumption. Furthermore, since the heat dissipation pipe is not misaligned, the refrigerator assembly process is improved.

[0014] In addition, the feature may be that one of the pipe fixing components is configured to be installed by clamping the first flange located at the front lower portion of the first storage box and is positioned by abutting against the first section, and the first section is arranged along the first flange at the upper portion of the first flange, and the other of the pipe fixing components is configured to be installed by clamping the second flange located at the front upper portion of the second storage box and is positioned by abutting against the second section, and the second section is arranged along the second flange at the lower portion of the second flange.

[0015] According to the present invention, the pipe fixing member can be held in a predetermined position without providing other connecting components, thereby improving operability, reducing positional deviations between the pipe fixing member and the heat dissipation pipe, and preventing a decrease in heat transfer efficiency.

[0016] Furthermore, a feature may be that the partition plate is formed to be mounted by clamping each of the pipe fixing members in a front-rear direction.

[0017] According to the present invention, the partition plate can be held in a predetermined position without providing other connecting components. In addition, since the configuration applies force in the direction that causes the partition plate to contact the heat dissipation pipe, the partition plate and the heat dissipation pipe can be more firmly in contact, thereby improving the heat transfer efficiency.

[0018] Furthermore, the feature may be that the pipe fixing member is configured so that at least a portion thereof does not overlap with the partition plate in the vertical direction in a front view, and visual confirmation is possible even after the partition plate is installed.

[0019] According to the present invention, the duct fixing member can be used as part of the appearance. Therefore, the duct fixing member can be formed into a shape that is difficult to form in the first storage box or the second storage box, thereby improving the appearance compared to the case where the duct fixing member is not used.

[0020] In addition, the feature may be that the first storage box and the second storage box are formed by vacuum forming, the first storage box has a lower section provided on a lower flange, the lower flange extends from the front to the lower side at the lower surface of the first storage box, the second storage box has an upper section provided on an upper flange, the upper flange extends from the front to the upper side at the upper surface of the second storage box, the upper end of the partition plate is configured to be located on the upper side of the lower section, and the lower end of the partition plate is configured to be located on the lower side of the upper section.

[0021] According to the present invention, by providing the duct securing member, compared to refrigerators without the duct securing member, when the first and second storage boxes are formed by vacuum forming, a portion having a predetermined size can be positioned toward the center of the partition plate in the vertical direction. This allows the front openings of the first and second storage boxes to be enlarged, thereby increasing their respective capacities.

[0022] Effects of the invention

[0023] According to the invention disclosed herein, a refrigerator can be provided having a shape that allows a heat dissipation duct to be easily and appropriately fixed to a predetermined position, thereby improving assembly workability of the heat dissipation duct and enhancing heat transfer efficiency to a partition plate.

[0029] The outline of a refrigerator 1 according to the present invention will be described with reference to the drawings. Figure 1 It is a perspective view of the refrigerator 1 in the embodiment of the present invention. Figure 2 This is an exploded view of the components that make up part of refrigerator 1. Refrigerator 1 includes a refrigerator body 2. When placed on a horizontal surface, it comprises, in order from the top, a door 3 rotatably mounted on the front of the refrigerator body 2, a first drawer 4, a second drawer 5, and a third drawer 6. Door 3 is coupled to the refrigerator body 2 at its upper and lower portions via hinges 7 located on at least one of its left and right sides, allowing it to rotate about the hinge axis.

[0030] like Figure 1 As shown, the refrigerator 1 of this embodiment includes a total of four storage compartments. The four storage compartments are composed of a first refrigerating compartment, a second refrigerating compartment, and a first freezer compartment and a second freezer compartment. The first refrigerating compartment can be opened by rotating the door 3 forward. The second refrigerating compartment, the first freezer compartment, and the second freezer compartment can be opened by moving the first drawer 4, the second drawer 5, and the third drawer 6 forward, respectively. Storage containers are provided in these drawers for users to store items.

[0031] The present invention is not limited to the structure according to this embodiment, and can also be applied to a refrigerator having a refrigerator compartment on the upper side and a freezer compartment on the lower side, which includes two storage compartments in total. In addition, not only the upper portion but also the lower portion can be configured to include a door body.

[0032] like Figure 2 As shown, the refrigerator 1 involved in this embodiment has two inner boxes, namely a refrigerator inner box 10 (or first storage box, the same below) located on the upper side and a freezer inner box 11 (or second storage box, the same below) located on the lower side, wherein at least the refrigerator inner box 10 and the freezer inner box 11 have openings on the front surface. The above-mentioned first refrigerator and second refrigerator rooms are divided by providing a partition structure inside a single refrigerator inner box 10. The same applies to the above-mentioned first freezer and second freezer rooms. In addition, it can also be configured so that the storage space for the stored items can be divided by using storage containers instead of the above-mentioned partition structure.

[0033] like Figure 2 As shown, the refrigerator 1 includes a heat dissipation duct 12 , a duct fixing member 20 , and a partition plate 30 , which are provided between a refrigerator interior box 10 located at an upper side and a freezer interior box 11 located at a lower side. Figure 3 yes Figure 2The components shown are assembled in a complete state, showing a cross-sectional view of the pipe fixing component 20 and the partition plate 30, etc., in which the pipe fixing component 20 and the partition plate 30 are enlarged. Figure 3 In the example, a dotted line indicates that a portion of the components described (in Figure 3 When the portion located behind the partition insulation portion 31 described later in the refrigerator is omitted, the boundary portion of the portion omitted in the figure is shown. The same applies to the other figures. The heat dissipation duct 12 can be composed of, for example, a portion of a condenser in a refrigeration cycle. When the compressor connected to the condenser (especially the outlet side of the compressor) is working, the high-temperature refrigerant can flow into the compressor from the inside of the heat dissipation duct 12. In this way, the heat generated by the compressor can be discharged. In addition, the partition plate 30 described later in contact with the heat dissipation duct 12 can be heated, and the temperature difference between the temperature in the refrigerator or freezer and the outside air temperature can be used to prevent condensation on the partition plate 30.

[0034] In this embodiment, the heat dissipation duct 12 is configured to pass between the refrigerator compartment 10 and the freezer compartment 11. Furthermore, the heat dissipation duct 12 is configured to pass between the first refrigerator compartment and the second refrigerator compartment, and between the first freezer compartment and the second freezer compartment. Figure 2 As shown, the heat dissipation ducts 12 are arranged so that the two heat dissipation ducts extend in the horizontal direction (lateral direction) and are arranged vertically (vertically) between the refrigerator compartment 10 and the freezer compartment 11. The two heat dissipation ducts are mounted on the duct fixing member 20.

[0035] In this embodiment, two pipe fixing members 20 are provided to match the number of pipes extending in the above-mentioned portion, one of which is fixed to the front lower portion of the refrigerator compartment 10, and the other is fixed to the front upper portion of the freezer compartment 11. Figure 3 As shown, the front surface of the pipe fixing member 20 is provided with claws 21 for clamping and securing the heat dissipation pipe 12 from above. The heat dissipation pipe 12 is inserted into the claws 21 and clamped in the gap between the claws 21, thereby easily and securely holding the pipe 12. After the pipe fixing member 20 is installed in the refrigerator interior 10 and the freezer interior 11, the heat dissipation pipe 12 is attached to the pipe fixing member 20. At least a portion of the heat dissipation pipe 12 attached to the pipe fixing member 20 is configured to protrude forward of the claws 21. As a result, the heat dissipation pipe 12, while secured to the claws 21, can contact the partition plate 30, described later.

[0036] For example, Figure 3As shown, the duct fixing member 20 can be fixed by sandwiching the inner box flange 10A (or the first flange, provided at the front lower portion of the first storage box, the same below) or the inner box flange 11A (or the second flange, provided at the front upper portion of the second storage box, the same below) in the front-to-back direction, wherein the inner box flange 10A extends downward from the refrigerator inner box 10, and the inner box flange 11A extends upward from the freezer inner box 11. By sandwiching the flanges in this way, the duct fixing member 20 can be coupled to the refrigerator inner box 10 or the freezer inner box 11 without using other connecting components such as screws. In addition, the position of the duct fixing member relative to the up-down direction can be set, for example, so that it is arranged at a predetermined position by abutting against the segment 10B (or the first end, the same below), which is provided along and above the inner box flange 10A.

[0037] The upper portion of the duct fixing member 20 to which the inner box flange 10A is mounted in the refrigerator interior box 10 may be configured to abut against a portion of the refrigerator interior box 10 (see FIG. Figure 3 ). Thus, the duct fixing member 20 can be held in the refrigerator interior box 10 more stably.

[0038] The pipe securing member 20 attached to the inner box flange 11A of the freezer compartment 11 can also be similarly configured to be positioned in a predetermined position by abutting against a segment 11B (or second end portion, hereinafter the same) disposed below the inner box flange 11A. Furthermore, the lower portion of the pipe securing member 20 attached to the inner box flange 11A of the freezer compartment 11 can also be configured to abut against a portion of the freezer compartment 11, for example.

[0039] A partition plate 30 is installed between the refrigerator compartment 10 and the freezer compartment 11. After the pipe fixing member 20 and the heat dissipation pipe 12 are installed in the refrigerator compartment 10 and the freezer compartment 11, Figure 3 As shown, between the lower end of the refrigerator interior box 10 and the upper end of the freezer interior box 11, a partition plate 30 is installed from the front thereof relative to each pipe fixing member 20 and the heat dissipation pipe 12. As described above, the partition plate 30 is assembled between the pipe members and abuts against the heat dissipation pipe 12. And further, the partition plate 30 is formed so as to be installed by clamping each of the pipe fixing members in the front-to-back direction. The partition plate 30 can be made of a metal plate, for example, to efficiently transfer the heat of the heat dissipation pipe 12. Hereinafter, the portion divided by the refrigerator interior box 10, the freezer interior box 11 and the partition plate 30 is referred to as a partition insulation portion 31. The partition insulation portion 31 is finally filled and foamed with a heat insulating material 32 to insulate the second refrigerator compartment and the first freezer compartment, and to insulate them from the outside air.

[0040] The partition plate 30 is configured to sandwich and retain the heat dissipation duct 12, the duct securing member 20, and the inner flange 10A of the refrigerator interior 10. Furthermore, the partition plate 30 is also configured to sandwich and retain the heat dissipation duct 12, the duct securing member 20, and the inner flange 11A of the freezer interior 11. This allows the partition plate 30 to be coupled between the refrigerator interior 10 and the freezer interior 11 without the use of other fastening components such as screws, and furthermore, provides a more secure contact with the heat dissipation duct 12.

[0041] Furthermore, according to the refrigerator 1 according to the present embodiment, the volumes of the refrigerator inner box 10 including the second refrigerator compartment and the freezer inner box 11 including the first freezer compartment can be improved. Figure 4 and Figure 3 Similarly, it is a cross-sectional view of the partition plate 30 between the refrigerator compartment 10 and the freezer compartment 11. Figure 3 , Figure 4 It is a schematic cross-sectional view of an example of a conventional refrigerator that does not have a pipe fixing member 20. Except that the partitioning and insulating portion 31 of the refrigerator does not have a pipe fixing member 20, the refrigerator includes a refrigerator interior box 10, a freezer interior box 11, a heat dissipation duct 12, a partition plate 30 and a heat insulating material 32, similar to the refrigerator 1 involved in the present invention. The partition plate 30 can also be visually confirmed after being assembled in the refrigerator and constitutes a part of the appearance of the refrigerator. Therefore, it is not preferred to damage the beautiful shape. If it is arranged on the front surface of a structure such as the refrigerator interior box 10, a gap may be generated between the partition plate 30 and the refrigerator interior box 10 and the freezer interior box 11. Therefore, in Figure 4 The illustrated refrigerator includes a lower section 10D and an upper section 11D. The lower section 10D is provided at a lower flange 10C extending from the front to the bottom of the refrigerator compartment 10, and is recessed toward the rear. The lower flange 10C extends from the front to the bottom of the refrigerator compartment 10. The upper section 11D is provided at an upper flange 11C extending from the front to the top of the freezer compartment 11. A partition plate 30 is provided between the sections 10D and 11D, with the upper end of the partition plate 30 positioned above the lower section 10D and the lower end of the partition plate 30 positioned below the upper section 11D. This prevents the formation of gaps between the sections, or minimizes the likelihood of gaps forming between the sections.

[0042] Without a duct fixing member 20 shaped to secure the heat dissipation duct 12 as described in this embodiment, the heat dissipation duct 12 cannot be secured until the foaming agent is filled, foamed, and the partition plate 30 is installed. Therefore, conventional processes employ methods such as tape to temporarily secure the heat dissipation duct 12 to the refrigerator interior 10 or freezer interior 11 to allow for the installation of the partition plate 30. In this case, the heat dissipation duct 12 may float or shift in position, preventing it from properly contacting the partition plate 30 and potentially causing condensation on the partition plate 30. Furthermore, heat may leak into the interior of the refrigerator or freezer, increasing power consumption.

[0043] However, the duct securing member 20 of this embodiment secures the heat dissipation duct 12, eliminating the need for adhesive tape. Furthermore, the duct 12 will not shift out of position. Therefore, the heat dissipation duct 12 can be properly positioned during refrigerator assembly, preventing the aforementioned problems. Furthermore, since the application of adhesive tape is unnecessary, assembly work can be reduced, minimizing the use of adhesive tape. Consequently, manufacturing costs can be reduced.

[0044] In a refrigerator that does not have a pipe fixing member 20, the partition plate 30 and its surrounding components are constructed with the dimensional relationship shown in the figure. Dimension a is the dimension formed by the lower surface of the interior of the refrigerator interior box 10 to the upper surface of the interior of the freezer interior box 11. Dimension a is also the width of the partition insulation part 31. Dimension a of the partition insulation part 31 is equivalent to the size of the width between the second refrigerator compartment and the first freezer compartment. Dimension b is the dimension between the refrigerator interior box 10 and the above-mentioned lower section 10D. Dimension c is the dimension of the partition plate 30 in the vertical direction. Dimension d, like dimension b, is the dimension between the freezer interior box 11 and the above-mentioned upper section 11D.

[0045] Generally speaking, a refrigerator's interior preferably has a larger storage volume relative to its overall dimensions. Furthermore, a larger front opening in a refrigerator compartment, for example, also improves convenience. A smaller dimension a of the insulating portion 31 increases the vertical dimensions of the second refrigerator compartment and the first freezer compartment, thereby increasing the storage volume and the front opening. Dimension a of the insulating portion 31 corresponds to the width of the member dividing the second refrigerator compartment from the first freezer compartment.

[0046] Preferably, the embodiment and the like of the present invention are formed by vacuum forming the refrigerator interior box 10 and the freezer interior box 11. Figure 4The refrigerator shown. Vacuum forming can produce relatively large shapes, but there is a disadvantage that the freedom of shape is small. For the size between the lower surface of the interior of the refrigerator compartment 10 and the lower section 10D provided at the lower flange 10C (i.e., dimension b), there are necessary conditions for forming. As this necessary condition, regarding dimension b, for example, it is generally required to have a size of about 10 mm or more. The same is true for the size between the upper surface of the interior of the freezer compartment 11 and the upper section 11D provided at the upper flange 11C (i.e., dimension d). Therefore, in the case of Figure 4 In the case of the structure shown in FIG. 1 in which the partition plate 30 is provided so as to be sandwiched between the refrigerator interior box 10 and the freezer interior box 11 , when the dimension c is set to 50 mm, the dimension a is set to at least 70 mm.

[0047] Regarding dimension c, its minimum required dimension is determined by the relationship between a portion of the first drawer 4 and a portion of the second drawer 5, which are arranged further forward of the partition plate 30. Based on this, it is difficult to configure this minimum required dimension to be smaller. Therefore, in order to reduce dimension a, it is necessary to reduce dimensions b and d.

[0048] According to the refrigerator of the embodiment of the present invention, Figure 3 As shown, the pipe fixing member 20 is arranged between the partition plate 30 and each inner box 10, 11. Thus, a structure can be formed in which the partition plate 30 is arranged between the pipe fixing members 20, rather than between each inner box 10, 11. Then, as shown in FIG. Figure 5 As shown in FIG, the dimensions b'' and d'' corresponding to the dimensions b and d related to the manufacturing requirements can be arranged to be located inside the upper and lower ends of the partition plate 30. As a result, the outer dimensions can be made Figure 4 The dimensions b' and d' corresponding to the dimensions b and d are reduced to a few millimeters (eg, about 3 to 5 mm). Therefore, by providing the duct fixing member 20, the dimension a' of the partitioning and insulating portion 31 can be made smaller than the dimension a.

[0049] In this embodiment, the duct securing member 20 is arranged so that at least a portion thereof does not overlap with the partition plate 30 in the vertical direction when viewed from the front. That is, the portion of the duct securing member 20 installed in the refrigerator compartment 10 can be visually confirmed from above the partition plate 30, and the portion of the duct securing member 20 installed in the freezer compartment 11 can be visually confirmed from below the partition plate 30.

[0050] Unlike the inner boxes 10 and 11, the pipe fixing member 20 is not preferably formed by vacuum molding, so it can be formed by injection molding or extrusion molding, for example. Generally, injection molding has a higher degree of freedom in shape than vacuum molding, and the accuracy of the dimensions after molding is also higher, so the pipe fixing member 20 can be formed in a more accurate shape. As a result, Figure 4 Compared to the case where the inner boxes 10, 11 and the partition plate 30 are installed in the refrigerator shown, the likelihood of a gap forming between the duct securing member 20 and the partition plate 30 is reduced. Furthermore, the duct securing member 20 can be formed to be thinner than the inner boxes 10, 11. Therefore, by configuring the duct securing member 20 so that it can be visually recognized even after the partition plate 30 is installed, the aesthetic appearance of the partitioned and insulating portion 31 can be improved.

[0051] The present invention is not limited to the illustrated embodiments, and various improvements and design changes can be made without departing from the spirit of the present invention.

[0052] Industrial applicability

[0053] As described above, according to the invention disclosed herein, a refrigerator can be provided having a shape that allows the heat dissipation duct to be easily and appropriately fixed in a predetermined position. This shape improves the assembly workability of the heat dissipation duct and enhances the heat transfer efficiency to the partition plate. Therefore, the refrigerator can be preferably applied to the industrial field of such refrigerators.
