Further, not only the upper tier but also the lower tier may be configured to include a door body.

As shown in FIG. 2, the refrigerator 1 according to the present embodiment has two inner boxes, a refrigerating chamber box 10 on the upper side and a freezing chamber box 11 on the lower side. The first refrigerating chamber and the second refrigerating chamber described above are partitioned by providing a partition inside a single refrigerating chamber box 10. The same applies to the first freezing chamber and the second freezing chamber. Further, the storage container may be used to partition the storage place of the contained object without partitioning by such a partition.

As shown in FIG. 2, the refrigerator 1 includes a heat radiation pipe 12, a pipe fixing member 20, and a partition plate 30 between the upper refrigerating room box 10 and the lower freezing room box 11. FIG. 3 is a cross-sectional view of a front-rear-upper and lower plane showing an enlarged view of the pipe fixing member 20, the partition plate 30, and the like in a state where the member shown in FIG. 2 is assembled. In FIG. 3, the alternate long and short dash line is a boundary portion with a portion omitted from the illustration when a part of the described components (the rear portion of the partition cutting heat portion 31 described later in FIG. 3 in FIG. 3) is omitted. show. The same applies to other figures. The heat dissipation pipe 12 is configured by using, for example, a part of the condenser in the refrigeration cycle, and can flow a high temperature refrigerant into the compressor when the compressor connected to the condenser is operating. Thereby, the heat generated by the compressor can be released. Further, it is possible to heat the partition plate 30 described later, which is in contact with the heat radiation pipe 12, and prevent the partition plate 30 from dew condensation due to the difference between the temperature in the refrigerating room or the freezing room and the outside air temperature.

In the present embodiment, the heat dissipation pipe 12 is configured to pass between the refrigerating chamber box 10 and the refrigerating chamber box 11. Further, it is configured to pass between the first refrigerating chamber and the second refrigerating chamber and between the first freezing chamber and the second freezing chamber. As shown in FIG. 2, in the heat radiating pipe 12, two heat radiating pipes are arranged in the horizontal direction (horizontal direction) so as to be arranged in the vertical direction (vertical direction) between the refrigerating room box 10 and the freezing room box 11. It is configured to extend in the direction).

In the present embodiment, two pipe fixing members 20 are provided according to the number of pipes extending to the above-mentioned portion, and one is fixed to the front lower portion of the refrigerating chamber box 10 and one to the front upper portion of the freezing chamber box 11. Will be done. As shown in FIG. 3, the pipe fixing member 20 is provided with a claw shape 21 on the front surface thereof for vertically sandwiching and fixing the heat radiation pipe 12. The pipe 12 can be easily and surely held by pushing the heat radiating pipe 12 into the claw shape 21 and sandwiching it in the gap between the claw shapes 21. The heat radiating pipe 12 is attached to the pipe fixing member 20 after the pipe fixing member 20 is attached to the refrigerating chamber box 10 and the refrigerating chamber box 11. At least a part of the heat radiating pipe 12 attached to the pipe fixing member 20 is configured to project forward from the claw shape 21. As a result, the heat radiating pipe 12 can be brought into contact with the partition plate 30 described later in a state of being fixed to the claw shape 21.

As shown in FIG. 3, the pipe fixing member 20 has, for example, an inner box flange 10A extending downward from the refrigerating room box 10 or an inner box flange 11A extending upward from the freezing room box 11 in the front-rear direction. It may be fixed so as to be sandwiched. By sandwiching the flange in this way, the pipe fixing member 20 can be connected to the refrigerating chamber box 10 or the freezing chamber box 11 without using another fastening component such as a screw. Further, the position of the pipe fixing member in the vertical direction may be provided so as to be arranged at a predetermined position by, for example, abutting the step portion 10B provided above along the inner box flange 10A. good.

The upper portion of the pipe fixing member 20 attached to the inner box flange 10A of the refrigerating chamber box 10 may be configured to abut on a part of the refrigerating chamber box 10, for example (see FIG. 3). Thereby, the pipe fixing member 20 can be more stably held in the refrigerating chamber box 10.

Similarly, the pipe fixing member 20 for the inner box flange 11A of the freezing chamber box 11 is brought into contact with the step portion 11B provided downward along the inner box flange 11A so as to be arranged at a predetermined position. It may be provided. Further, the lower portion of the pipe fixing member 20 attached to the inner box flange 11A of the freezing chamber box 11 may be configured to come into contact with, for example, a part of the freezing chamber box 11.

A partition plate 30 is attached between the refrigerating chamber box 10 and the freezing chamber box 11. After the pipe fixing member 20 and the heat dissipation pipe 12 are attached to the refrigerating chamber box 10 and the refrigerating chamber box 11, the partition plate 30 has a lower end of the refrigerating chamber box 10 and an upper end of the refrigerating chamber box 11 as shown in FIG. In between, it is attached to each pipe fixing member 20 and the heat dissipation pipe 12 from the front. As described above, the partition plate 30 is assembled so as to be in contact with the heat dissipation pipe 12. The partition plate 30 is made of, for example, sheet metal, and heat is efficiently transferred by the heat dissipation pipe 12. Hereinafter, the portion partitioned by the refrigerating chamber box 10, the freezing chamber box 11, and the partition plate 30 will be referred to as a partition heat section 31. Finally, the heat insulating material 32 is filled and foamed in the partition heat section 31, to insulate between the second refrigerating chamber and the first freezing chamber, and between them and the outside air.

The partition plate 30 is held by sandwiching the heat radiation pipe 12, the pipe fixing member 20, and the inner box flange 10A of the refrigerating chamber box 10, and sandwiching and holding the heat radiation pipe 12, the pipe fixing member 20, and the inner box flange 11A of the refrigerating chamber box 11. It is configured to be. As a result, the partition plate 30 can be coupled between the refrigerating chamber box 10 and the refrigerating chamber box 11 without using another fastening component such as a screw, and the heat radiating pipe 12 can be more reliably contacted with the partition plate 30. can.

Further, according to the refrigerator 1 according to the present embodiment, it is possible to improve the volumes of the refrigerating chamber box 10 including the second refrigerating chamber and the freezing chamber box 11 including the first freezing chamber. FIG. 4 is a cross-sectional view of a partition plate 30 between the refrigerating chamber box 10 and the freezing chamber box 11 as in FIG. 3, and is a conventional refrigerator having no pipe fixing member 20 with respect to FIG. It is a schematic cross-sectional view of an example. The partition cutting heat portion 31 of the refrigerator is the same as the refrigerator 1 according to the present invention except that it does not have the pipe fixing member 20, the refrigerating chamber box 10, the freezing chamber box 11, the heat radiation pipe 12, the partition plate 30, and the heat insulating material 32. It is equipped with. Since the partition plate 30 is visible even after the refrigerator is assembled and forms a part of the appearance of the refrigerator, a shape that spoils the aesthetic appearance is not preferable. If it is arranged in front of the refrigerating room box 10 or the like, a gap may occur between the partition plate 30 and the refrigerating room box 10 and the freezing room box 11. Therefore, in the refrigerator shown in FIG. 4, the lower flange 10C extending downward from the front of the lower surface of the refrigerating chamber 10 extends rearward to the lower stage portion 10D, and extends from the front to the upper surface of the freezing chamber 11. An upper step portion 11D in which the upper flange 11C is recessed rearward is provided. Then, the partition plate 30 is arranged between the step portions 10D and 11D so that a gap or the like does not occur or the possibility of the gap is reduced as much as possible.

When a member having a shape for fixing the heat radiation pipe 12 such as the pipe fixing member 20 according to the present embodiment is not provided, the heat radiation pipe 12 is fixed until the partition plate 30 is attached by filling and foaming with a foaming agent. Can't. Therefore, conventionally, the work of temporarily fixing the pipe 12 to the refrigerating room box 10 or the freezing room box 11 by using an adhesive tape, for example, and attaching the partition plate 30 has been performed. In this case, the pipe 12 may float or be displaced, the pipe 12 may not properly contact the partition plate 30, and dew condensation may occur on the partition plate 30. In addition, heat may leak to the inside of the refrigerator or freezer, increasing power consumption.

However, according to the pipe fixing member 20 according to the present embodiment, since the heat radiation pipe 12 can be fixed, it is not necessary to fix it with the adhesive tape, and the position of the pipe 12 does not shift. Therefore, the position of the heat radiating pipe 12 can be appropriately maintained during the assembling work of the refrigerator, and the occurrence of the above-mentioned problems can be prevented. Further, since it is not necessary to attach the adhesive tape, the amount of assembling work can be reduced and the adhesive tape can be reduced. Therefore, the manufacturing cost can be reduced.

In a refrigerator without a pipe fixing member 20, the partition plate 30 and its peripheral parts are configured in a dimensional relationship as shown in the figure. The dimension a is a dimension composed of an inner lower surface of the refrigerating chamber box 10 and an inner upper surface of the freezing chamber box 11. The dimension a is also the width of the partition cutting heat portion 31. The dimension a of the partition cutting heat unit 31 corresponds to the size of the width between the second refrigerating chamber and the first freezing chamber. The dimension b is the dimension between the refrigerating chamber box 10 and the lower stage portion 10D described above. The dimension c is a dimension in the vertical direction of the partition plate 30. The dimension d is the dimension between the freezing chamber box 11 and the above-mentioned upper stage portion 11D, similarly to the dimension b.

Generally, it is preferable that the refrigerator has a large storage volume in the refrigerator with respect to its external dimensions. In addition, the convenience is improved when the frontage opening of the refrigerating room or the like is increased. The smaller the dimension a of the partition heat portion 31 corresponding to the width corresponding to the width of the component separating the second refrigerating chamber and the first freezing chamber, the larger the vertical dimension of the second refrigerating chamber and the first freezing chamber can be. The accommodation volume and frontage opening can be increased.

In the embodiment according to the present invention and the refrigerator as shown in FIG. 4, it is preferable that the refrigerating chamber box 10 and the freezing chamber box 11 are formed by vacuum forming. Vacuum forming can create a relatively large shape, but has the disadvantage of having a small degree of freedom in shape, and has the lower surface inside the refrigerating chamber box 10 and the lower step portion 10D provided on the lower flange 10C described above. There is a molding requirement in the dimension between (ie, dimension b). As the requirement, the dimension b is generally required to have a size of, for example, about 10 mm or more. The same applies to the dimension (that is, the dimension d) between the inner upper surface of the freezing chamber box 11 and the upper step portion 11D provided on the upper flange 11C described above. Therefore, in the case of a configuration in which the partition plate 30 is sandwiched between the refrigerating chamber box 10 and the freezing chamber box 11 as shown in FIG. 4, if the size of the dimension c is 50 mm, the dimension a is at least 70 mm. It becomes.

The dimension c is more than the minimum required dimension because the minimum required dimension is determined by the relationship between the part of the first drawer 4 arranged further in front of the partition plate 30 and the part of the second drawer 5. It's difficult to make it smaller. Therefore, in order to reduce the dimension a, it is necessary to reduce the dimension b and the dimension d.

According to the refrigerator of the embodiment according to the present invention, as shown in FIG. 3, the pipe fixing member 20 is arranged between the partition plate 30 and the inner boxes 10 and 11. Thereby, the partition plate 30 can be configured to be arranged not between the inner boxes 10 and 11 but between the pipe fixing members 20. Then, as shown in FIG. 5, the dimensions b ", d" corresponding to the dimensions b and d related to the manufacturing requirements can be configured to be located inside the upper and lower ends of the partition plate 30. As a result, the external dimensions b'and d'corresponding to the dimensions b and d shown in FIG. 4 can be reduced to about several mm (for example, about 3 to 5 mm). Therefore, by providing the pipe fixing member 20, the dimension a'of the partition cutting heat portion 31 can be made smaller than the dimension a.

In the present embodiment, at least a part of the pipe fixing member 20 is configured so as not to overlap the partition plate 30 in the vertical direction in the front view. That is, a part of the pipe fixing member 20 attached to the refrigerating room box 10 can be visually recognized above the partition plate 30, and a part of the pipe fixing member 20 attached to the freezing room box 11 can be seen on the partition plate 30. It can be seen below.

Unlike the inner boxes 10 and 11, the pipe fixing member 20 is not preferably formed by vacuum forming, and therefore can be formed by, for example, injection molding or extrusion molding. In general, injection molding has a higher degree of freedom in shape than vacuum forming, and the accuracy of the dimensions after molding is also high, so that the pipe fixing member 20 can be formed with a more accurate shape. As a result, the possibility that a gap between the pipe fixing member 20 and the partition plate 30 is generated is reduced as compared with the case of the inner boxes 10 and 11 and the partition plate 30 in the refrigerator as shown in FIG. Further, it is possible to form a finer shape than the inner boxes 10 and 11. Therefore, by providing the pipe fixing member 20 so that it can be visually recognized even after the partition plate 30 is attached, it is possible to improve the aesthetic appearance of the partition cutting heat portion 31.

The present invention is not limited to the exemplified embodiments, and various improvements and design changes can be made without departing from the gist of the present invention.

As described above, according to the invention according to the present disclosure, by making it possible to easily and appropriately fix the heat radiating pipe to a predetermined position, the workability of assembling the heat radiating pipe is improved, and the heat transfer efficiency to the partition plate is improved. Since it is possible to provide a refrigerator having a shape capable of improving the above, it can be suitably used in the industrial field of this type of refrigerator.
