A control device cover 27 that covers the control device 8 is provided, and the connection line 10 has a configuration that is covered by the wireless communication device cover 93 and the control device cover 27. With this additional configuration, the refrigerator 1 according to the first embodiment has an effect of suppressing the connection line 10 from being exposed to the outside. By suppressing the exposure of the connecting wire 10 to the outside, for example, the design can be improved, or the connecting wire 10 can be prevented from being caught and broken during transportation.

A modified example of the refrigerator 1 according to the first embodiment will be described.

In the refrigerator 1 according to the first embodiment, a screw is used as the fixing member 11, but the present invention is not limited to this. For example, a double-sided tape may be used for the fixing member, and the wireless communication device and the housing may be fixed with the double-sided tape. Further, a magnet may be used as the fixing member, the magnet may be fixed to the wireless communication device, and the wireless communication device may be fixed to the outer box of the housing by magnetic force. When fixing with these double-sided tapes or magnets, the recess 22a of the heat insulating material 22 is unnecessary and the upper surface space 28 may not be formed.

However, when double-sided tape is used as the fixing member, the adhesive strength of the double-sided tape deteriorates over time, and the force of fixing the wireless communication device weakens. Further, when a magnet is used as the fixing member, the magnetic force of the magnet hinders the transmission and reception of radio waves of the wireless communication device. Therefore, in the refrigerator 1 according to the first embodiment, as an additional configuration, the housing 2 is located on the outer box 21 facing the space outside the housing 2 and on the storage space 23 side of the outer box 21. A heat insulating material 22 is provided, and an upper surface space 28 is formed between the outer box 21 and the heat insulating material 22 on the upper surface 25 of the housing 2, and at least a part of the fixing member 11 is the upper surface space 28. It is a configuration located in. With this configuration, the fixing member 11 and a part of the outer box 21 can be fitted, and the wireless communication device 9 can be firmly fixed.

Further, the fixing member fitted to the outer box 21 does not have to be a screw. For example, the refrigerator 1 according to the following modification of the first embodiment may be configured. In the refrigerator 1 according to the modified example of the first embodiment, the configuration except for the parts described below is the same as that of the refrigerator 1 of the first embodiment, and thus the description thereof will be omitted.

FIG. 7 is an enlarged view of a portion corresponding to region C in FIG. 5 of the refrigerator according to the modified example of the first embodiment. In the refrigerator 1 of the modified example of the first embodiment, a fitting portion 95 protruding into the storage space 23 is provided in front of the wireless communication device cover 93 of the wireless communication device 9. Further, the tip of the fitting portion 95 is formed with a claw portion 95a protruding toward the inner space 93a of the wireless communication device cover. Further, a hole 21b into which the fitting portion 95 can be inserted is formed in the outer box 21 of the housing 2. Further, a recess 22a is formed in the heat insulating material 22 at a position overlapping the hole 21b in the vertical direction, and an upper surface space 28 is formed between the outer box 21 of the housing 2 and the heat insulating material 22. Further, the size of the recess 22a in the front-rear direction is larger than the size of the hole 21b in the front-rear direction. Therefore, the upper surface space 28 is also formed at a position where the edge portion 21c, which is the edge of the hole portion 21b, overlaps in the downward direction. Then, by inserting the fitting portion 95 into the hole portion 21b, the claw portion 95a and the edge portion 21c are fitted, and the wireless communication device 9 is fixed to the housing 2. In the case of the refrigerator 1 of the modified example of the first embodiment, the fitting portion 95 corresponds to the fixing member.

Further, in the refrigerator 1 according to the first embodiment, the vertical dimension of the upper surface space 28 is such that the shaft portion of the screw does not come into contact with the heat insulating material 22, but the dimension is not limited to this. For example, the heat insulating material is a urethane heat insulating material, and the urethane heat insulating material before inserting the screw does not have a space on the upper surface, and the screw is inserted into the screw hole of the outer box and the screw hole of the wireless communication device cover. The screws may pierce the urethane insulation when doing so. In this case, the holes formed in the urethane heat insulating material that are perforated by the screws correspond to the upper surface space.

However, when the urethane heat insulating material is drilled with screws, the heat insulating property may deteriorate, such as cracks in the urethane when drilling. Therefore, in the refrigerator 1 according to the first embodiment, as an additional configuration, the vertical dimension of the upper surface space 28 is the vertical dimension of the portion of the fixing member 11 located inside the upper surface space 28. Has a longer configuration. Due to this additional configuration, since the fixing member 11 and the heat insulating material 22 do not come into contact with each other, it is possible to prevent the fixing member 11 from coming into contact with each other when the fixing member 11 is attached and to reduce the heat insulating property of the heat insulating material 22.

Further, in the refrigerator 1 according to the first embodiment, the storage space 23 is divided into a plurality of storage chambers by the partition member 26, but the present invention is not limited to this. For example, the storage space may be a refrigerator that does not have a partition member and forms only one storage room.

Further, in the refrigerator 1 according to the first embodiment, the opening / closing door 3 is a double door, but the present invention is not limited to this. For example, it may be a refrigerator with a single door in which the opening of the housing 2 is closed by either an opening / closing door whose right end is supported by a hinge or an opening / closing door whose left end is supported by a hinge. Absent.

Embodiment 4.
Next, the refrigerator 1 according to the fourth embodiment will be described. The refrigerator 1 according to the fourth embodiment has a different structure of the heat insulating material 22 as compared with the refrigerator 1 according to the first embodiment. Since the refrigerator 1 according to the fourth embodiment has the same configuration as the refrigerator 1 according to the first embodiment except for the configuration of the heat insulating material 22, the description thereof will be omitted.

FIG. 12 is a cross-sectional view showing a portion corresponding to the BB cross section in FIG. 3 of the refrigerator according to the fourth embodiment. FIG. 13 is an enlarged view of the area E in FIG. 12 of the refrigerator according to the fourth embodiment.

The heat insulating material 22 will be described. The heat insulating material 22 is composed of a foam heat insulating material 22b such as urethane and a vacuum heat insulating material 22c having a core material surrounded by a film and having a vacuum inside the film. Further, the vacuum heat insulating material 22c is located on the outer box side of the foam heat insulating material 22b. That is, on the upper surface portion 25, the vacuum heat insulating material 22c is located above the foam heat insulating material 33b.

A recess 22a is formed in the vacuum heat insulating material 22c at a position overlapping the screw hole 21a formed in the outer box 21 in the vertical direction. The recess 22a is formed on the surface of the vacuum heat insulating material 22c facing the outer box 21, and is recessed toward the storage space 23 from the surroundings. Therefore, an upper surface space 28 is formed between the outer box 21 of the housing 2 and the vacuum heat insulating material 22c.

Here, the vertical dimension of the upper surface space 28 is longer than the vertical dimension of the portion of the fixing member 11 located inside the upper surface space 28, and the fixing member 11 does not come into contact with the vacuum heat insulating material 22c. That is, the size of the upper surface portion space 28 is such that the fixing member 11 does not come into contact with the vacuum heat insulating material 22c.

As described above, in the refrigerator 1 according to the fourth embodiment, similarly to the refrigerator 1 according to the first embodiment, the storage space 23 for storing the cooling target is formed inside, and the upper surface portion 25 located above the storage space 23 is provided. Controls the housing 2, the outer box 21 that is a part of the housing 2 and faces the space outside the housing 2, the cooling device 5 that supplies cooled air to the storage space 23, and the cooling device 5.

With this configuration, the refrigerator 1 according to the fourth embodiment has the same effect as that described in the first embodiment.

Further, the refrigerator 1 according to the fourth embodiment has a configuration in which the vacuum heat insulating material 22c is used as the heat insulating material 22 as an additional configuration. Unlike foam insulation, vacuum insulation cannot be punctured. Therefore, when the connecting wire is laid in the wall of the housing and the vacuum heat insulating material is used as the heat insulating material as in the refrigerator disclosed in Patent Document 1, the following problems occur. When pulling out the connecting wire laid in the wall to the upper surface, the vacuum heat insulating material cannot be placed at the place where the connecting wire is pulled out. However, in the refrigerator 1 according to the fourth embodiment, since the connecting wire 10 is laid outside the housing 2, the vacuum heat insulating material can be arranged over the entire upper surface portion, and the connecting wire is laid in the wall. The heat insulating performance is higher than that of the case. Therefore, the refrigerator 1 according to the fourth embodiment has a more remarkable effect by having this additional configuration.

Further, in the refrigerator 1 according to the fourth embodiment, as an additional configuration, the housing 2 has the heat insulating material 22 located closer to the storage space 23 than the outer box 21, and the heat insulating material 22 is the foam heat insulating material 22b. The vacuum heat insulating material 22c is located on the outer box 21 side of the foam heat insulating material 22b, and the upper surface space 28 is formed between the outer box 21 and the vacuum heat insulating material 22c. , At least a part of the fixing member 11 has a structure located in the upper surface space 28. By forming the upper surface space 28, this additional configuration prevents the fixing member 11 and the vacuum heat insulating material 22c from coming into contact with each other to damage the film of the vacuum heat insulating material 22c and impair the heat insulating performance of the vacuum heat insulating material 22c. It has a suppressing effect. Further, in general, the inner box 20 is provided with interior lighting or the like (not shown). Here, when the vacuum heat insulating material 22c is located closer to the inner box 20 than the foam heat insulating material 22b, the film of the vacuum heat insulating material 22c may be damaged by an attachment for fixing the lighting inside the refrigerator. Therefore, in this additional configuration, the vacuum heat insulating material 22c is located closer to the outer box 21 than the foam heat insulating material 22b, which has the effect of suppressing the heat insulating property of the vacuum heat insulating material 22c from being impaired.

A modified example of the refrigerator 1 according to the fourth embodiment will be described.
