Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals are given to the same components. Their names and functions are also identical. Therefore, detailed descriptions thereof will not be repeated.

[ first embodiment ]

(integral construction of refrigerator)

In the present embodiment, a refrigerator 1 will be described as an example. Fig. 1 shows an external appearance of a back surface side of a refrigerator 1 according to the present embodiment. The refrigerator 1 is mainly composed of a heat insulating box (main body) 50 and various doors (not shown). The refrigerator 1 includes a plurality of storage compartments such as a refrigerator compartment, a vegetable compartment, a freezer compartment, and an ice making compartment.

In the present embodiment, the surface provided with the door is referred to as the front surface (front surface) of the refrigerator. Based on the front surface, the respective surfaces of the heat insulating box (main body) 50 constituting the refrigerator 1 are an upper surface portion 50a, a side surface portion 50b, a rear surface portion 50c, and a bottom surface portion, based on the positions existing when the refrigerator 1 is installed in a normal state. When the heat insulation box 50 is viewed from the front in a state where the refrigerator 1 is placed on the installation surface, the left-right direction (the lateral direction orthogonal to the up-down direction) is referred to as the left-right direction of the heat insulation box 50 (or the refrigerator 1 or the like). In a state where the refrigerator 1 is placed on the installation surface, the vertical direction of the heat-insulating box 50 (the vertical direction orthogonal to the left-right direction) is referred to as the vertical direction of the heat-insulating box 50 (or the refrigerator 1, etc.).

The heat insulating box 50 has a heat insulating structure for insulating each storage compartment from the surroundings. The heat insulating box 50 mainly includes an outer box 51, an inner box 52, and a heat insulating layer 53.

The outer case 51 forms an outer surface of the heat insulating case 50. The outer case 51 constitutes an upper surface portion 50a, a side surface portion 50b, a rear surface portion 50c, a bottom surface portion, and the like of the heat insulating case 50. The upper surface portion 50a, the side surface portion 50b, and the rear surface portion 50c are each formed of a thin plate-like metal plate. The metal plate forming the back surface portion 50c is also referred to as a back plate. The inner box 52 forms an inner surface of the heat insulation box 50.

The heat insulating layer 53 is provided in the space between the outer case 51 and the inner case 52. The heat insulating layer 53 is made of, for example, a foamed heat insulating material. The foamed heat insulating material 56 may be formed of, for example, foamed polyurethane (also referred to as rigid polyurethane foam) or the like.

An electric unit 60 is provided on the rear side of the upper surface portion 50a of the heat insulating box 50. In the present embodiment, the electric unit 60 is disposed at a substantially central portion in the left-right direction on the upper surface portion 50 a. The electric component unit 60 includes an electric substrate 61, a lower case member 62, an upper case member 63, and the like (see fig. 25). Electronic components such as a control unit and a memory are mounted on the electric substrate 61. The electric substrate 61 is disposed in a case formed by a lower case member 62 and an upper case member 63.

The lower case member 62 is formed of, for example, a resin material. The upper case member 63 is formed of, for example, a metallic material. The lower case member 62 is located on the lower side of the electric component substrate 61. The upper case member 63 is provided so as to cover the electric substrate 61 from above. By disposing the electric substrate 61 in the case formed by the lower case member 62 and the upper case member 63, water, dust, and the like can be prevented from falling onto the electric substrate 61.

A power line 71 extending downward along the rear surface 50c of the heat insulating box 50 is provided on the rear surface side of the electric unit 60. One end of the power supply line 71 is connected to the electric substrate 61 (see fig. 4). A power plug (not shown) is provided at the other end of the power cord 71. This allows electric power to be supplied to the electric substrate 61 and the like via the power supply line 71.

A pair of handle portions 31a and 31b are provided at left and right corner portions above the rear surface side of the heat insulating box 50. The pair of handle portions 31a and 31b have a laterally symmetrical structure. The handle portion 31a is located on the left side (right side viewed from the back side of the refrigerator 1) as viewed from the front side of the refrigerator 1. The handle portion 31b is located on the right side (on the left side as viewed from the back side of the refrigerator 1) as viewed from the front side of the refrigerator 1. By providing such handle portions 31a and 31b, an operator can carry the refrigerator 1 by hanging his/her hands on the respective handle portions 31a and 31b when carrying the refrigerator 1 or the like.

(construction of cover Member of Power cord)

Next, the structure of the cover member 72 covering the power line 71 will be described. Fig. 2 shows a structure of the back surface side of the refrigerator 1 with the cover member 72 removed. Fig. 3 shows a structure of an upper portion of the back surface side of the refrigerator 1. Fig. 4 shows a sectional configuration of an A-A line portion of the back surface portion of the refrigerator 1 shown in fig. 3. Fig. 5 shows a sectional configuration of a line B-B portion of the back surface portion of the refrigerator 1 shown in fig. 3. Fig. 6 shows a sectional configuration of a C-C line portion of the back surface portion of the refrigerator 1 shown in fig. 3.

As shown in fig. 2, the power cord 71 extends from the outlet 64 provided on the rear surface side of the lower case member 62 and the upper case member 63 to the outside of the electric unit 60. The power cord 71 extends downward from the rear surface side of the heat insulation box 50. In fig. 1, 2, and the like, illustration of a lower portion of the power supply line 71 is omitted.

A cover member 72 for covering the power cord 71 is provided at the outlet 64 of the electric unit 60. The cover member 72 covers a portion (specifically, an upper portion) of the power supply line 71 extending from the outlet 64 to the outside of the electric unit 60. The cover member 72 is fixed to the heat insulating box 50 by a plurality of screws 73 (4 screws 73 in the example shown in fig. 2). By providing such a cover member 72, the power supply line 71 extending downward from the electric unit 60 can be protected.

In the present embodiment, the cover member 72 covers at least a part of the horizontal extension portion 71a of the power line 71 and the vertical extension portion 71b of the power line 71 continuous from the horizontal extension portion 71a (see fig. 4). With this configuration, the vicinity of the connection portion of the power supply line 71 with the electric substrate 61 is covered with the cover member 72, so that the load applied to the connection portion of the power supply line 71 with the electric substrate 61 can be reduced.

In the present embodiment, the cover member 72 is covered from above the outlet 64 of the electric unit 60 (see fig. 4). With this configuration, the outlet 64 of the electric unit 60 can be completely covered, and thus, the liquid such as water can be prevented from entering the electric unit 60 from the outlet 64.

The cover member 72 is obtained by molding a metal material, a resin material, or the like into a predetermined shape, for example. The cover member 72 mainly includes a wire arrangement portion 81, fixing portions 82a and 82b.

As shown in fig. 4 and 6, in a state where the cover member 72 is attached to the refrigerator 1, the wire arrangement portion 81 has a space extending in the up-down direction inside. A power supply line 71 is disposed in the space.

The fixing portions 82a and 82b are provided at side end portions of the wire arrangement portion 81. In a state where the cover member 72 is attached to the refrigerator 1, the fixing portions 82a and 82b are in contact with the rear surface portion 50c of the heat insulation box 50 (see fig. 5 and 6). The fixing portion 82a is located on the left side of the wire arrangement portion 81 as viewed from the back side of the refrigerator 1. The fixing portion 82b is located on the right side of the wire arrangement portion 81 as viewed from the back side of the refrigerator 1.

A plurality of holes into which the screws 73 are inserted are provided in the fixing portions 82a and 82b. A screw fixing hole 73a (see fig. 2) is provided in a position corresponding to the hole in the rear surface portion 50c of the heat insulating box 50. Further, screw receiving portions 75 and 75 (see fig. 6) are provided in the heat insulating box 50 at positions corresponding to the fixing portions 82a and 82b. The screw receiving portion 75 is formed of, for example, a resin material or a metal material, and is formed with a female screw in advance at a position corresponding to the screw fixing hole 73a or by screwing the screw 73. Thus, the fixing portions 82a and 82b can be reliably fixed to the rear surface portion 50c of the heat insulation box 50.

The screw receiving portion 75 may be attached to the back surface side of the back surface portion 50c of the heat insulating box 50 by an adhesive tape or the like. Accordingly, the screw receiving portion 75 can be easily temporarily fixed to the rear surface side of the rear surface portion 50c of the heat insulating box 50, and leakage of the foamed heat insulating material filled in the heat insulating box 50 from the screw fixing hole 73a can be suppressed.

For comparison, the configuration of the periphery of the electric unit 60 of the conventional refrigerator 901 will be described. Fig. 24 shows an external appearance of a back side of a conventional refrigerator 901. Fig. 25 is a perspective view showing a state in which the upper case member 63 of the electric loading unit 60 is removed in the refrigerator 901 shown in fig. 24.

The cover member 72 is not provided on the refrigerator 901. Therefore, as shown in fig. 24, the power line 71 coming out of the outlet 64 of the electric unit 60 is exposed to the outside. In this way, if the power cord 71 is exposed at the outlet 64 of the electric device unit 60, for example, during transportation of the refrigerator or the like, a load is applied to the connection portion between the power cord and the electric device substrate, which may cause breakage of the power cord and the electric device substrate. In addition, in an environment where moisture is easily attached to the refrigerator such as when the refrigerator 901 is installed outdoors, the moisture attached to the power line 71 may be transferred to the outlet 64 of the electric unit 60 and may be immersed in the electric unit 60. In general, the outlet 64 of the electric unit 60 is provided with a waterproof seal, but it is considered that if moisture stagnates in the outlet 64 of the electric unit 60 for a long time, the waterproof property of the waterproof seal becomes poor.

In contrast, the outlet 64 of the electric unit 60 in the refrigerator 1 of the present embodiment is provided with a cover member 72 that covers the power cord 71. By providing such a cover member 72, the power supply line 71 extending downward from the electric unit 60 can be protected. Further, since the cover member 72 prevents moisture from directly entering the outlet 64 of the electric unit 60 and fixes the power cord 71 to extend downward, moisture adhering to the power cord 71 can be prevented from being transmitted to the outlet 64 of the electric unit 60. Therefore, moisture can be prevented from adhering to the outlet 64 of the electric unit 60.

(summary of the first embodiment)

As described above, the refrigerator 1 according to the present embodiment includes the heat-insulating box (main body portion) 50, the electric unit 60, and the power cord 71. The heat insulating box 50 has an upper surface portion 50a and a rear surface portion 50c. The electric unit 60 is disposed on the upper surface 50a of the heat insulation box 50. The electric component unit 60 includes an electric component substrate 61. The power supply line 71 is connected to the electric substrate 61. The power cord 71 extends downward from the rear surface side of the heat insulation box 50, and a cover member 72 for covering the power cord 71 is provided at the outlet 64 of the electric unit 60.

With the above configuration, the power supply line 71 extending downward from the electric unit 60 can be protected. Further, the outlet 64 of the electric unit 60 is covered with the cover member 72, whereby it is possible to make it difficult for moisture to enter the electric unit 60.

In the refrigerator 1 according to the present embodiment, the cover member 72 covers at least a part of the horizontal extension portion 71a of the power line 71 and the vertical extension portion 71b continuous from the horizontal extension portion 71a (see fig. 4). In this way, the cover member 72 extends downward from the electric unit 60 and opens downward, so that foreign matter such as water and dust is less likely to enter the cover member 72 and the electric unit 60.

Further, the cover member 72 preferably covers a portion of an appropriate length, for example, 15cm or more from the upper end of the refrigerator 1. Thus, the power cord 71 is covered with the cover member 72 until the portion below the handle portions 31a and 31b and the electric unit 60, and the power cord 71 exposed below the cover member 72 can be prevented from being caught by the handle portions 31a and 31b and the electric unit 60 when the refrigerator is transported and used, and the power cord 71 can be protected. Further, it is possible to configure: in the case where liquid such as water is sprinkled on the upper surface portion 50a of the refrigerator 1, it is more difficult for the liquid to be immersed into the inside of the electric unit 60 from the outlet 64.

[ second embodiment ]

Next, a second embodiment of the present invention will be described. In the second embodiment, a refrigerator in which a vacuum heat insulating material is provided in a heat insulating box 50 will be described as an example. In the refrigerator 1 of the present embodiment, the configuration of a cover member covering a power cord is different from that of the first embodiment. The cover member may have substantially the same structure as that of the first embodiment.

Fig. 7 shows an appearance of the back side of the refrigerator 1 according to the present embodiment. Fig. 8 shows a structure of an upper portion of the back surface side of the refrigerator 1. Fig. 9 shows a sectional configuration of an A-A line portion of the back surface portion of the refrigerator 1 shown in fig. 8. Fig. 10 shows a sectional configuration of a B-B line portion of the back surface portion of the refrigerator 1 shown in fig. 8. Fig. 11 shows a sectional configuration of a C-C line portion of the back surface portion of the refrigerator 1 shown in fig. 8.

The refrigerator 1 is mainly composed of a heat insulating box (main body) 50 and various doors (not shown). The heat insulating box 50 has a heat insulating structure for insulating each storage compartment from the surroundings. The heat insulating box 50 mainly includes an outer box 51, an inner box 52, and a heat insulating layer 53. The outer case 51 and the inner case 52 can be constructed in the same manner as in the first embodiment.

The heat insulating layer 53 is made of, for example, a foamed heat insulating material and a vacuum heat insulating material (VIP) 55. The foamed heat insulating material 56 may be formed of, for example, foamed polyurethane (also referred to as rigid polyurethane foam) or the like. The vacuum heat insulating material 55 is a sheet-like or plate-like heat insulating material. The vacuum heat insulating material 55 is disposed on, for example, a side surface, an upper surface, a bottom surface, a back surface, and the like of the refrigerator 1. By providing the vacuum heat insulating material 55 in the heat insulating layer 53, the heat insulating performance of the heat insulating box 50 can be further improved.

In the present embodiment, the vacuum heat insulating material 55 is disposed on the outer case 51 side of the heat insulating case 50. For example, a vacuum heat insulating material 55 is disposed on the rear surface 50c of the heat insulating box 50 so as to be in contact with the back plate of the outer box 51 (see fig. 9, etc.).

An electric unit 60 is provided on the rear side of the upper surface portion 50a of the heat insulating box 50. As in the first embodiment, the electric component unit 60 includes an electric substrate 61, a lower case member 62, an upper case member 63, and the like (see fig. 25). As in the first embodiment, the power cord 71 extends from the outlets 64 on the rear sides of the lower case member 62 and the upper case member 63, and extends downward along the rear surface 50c of the heat insulation box 50. In fig. 7 and the like, illustration of a lower portion of the power supply line 71 is omitted.

A portion of the power cord 71 extending from the outlet 64 of the electrical component unit 60 is covered with a cover member 172. The cover member 172 (specifically, the mounting member 181) is fixed to the heat insulating box 50 by a plurality of screws 73. Fig. 7 shows a state before the mounting member 181 is mounted on the back surface 50c of the refrigerator 1. By providing such a cover member 172, the power supply line 71 extending downward from the electric unit 60 can be protected.

As in the first embodiment, the cover member 172 covers at least a part of the horizontal extension portion 71a of the power line 71 and the vertical extension portion 71b of the power line 71 continuous from the horizontal extension portion 71a (see fig. 9).

The cover member 172 is mainly composed of a mounting member 181, fixing portions 182a and 182b, and a wire arrangement portion 183.

The mounting member 181 is obtained by molding a plate-like member made of a metal material, a resin material, or the like into a predetermined shape, for example. The mounting member 181 is fixed to the heat insulating box 50 by a plurality of screws 73 (4 screws 73 in the example shown in fig. 7). More specifically, the mounting member 181 is fixed to the fixing portions 182a and 182b provided on the back surface portion 50c of the heat insulating box 50.

The fixing portions 182a and 182b and the wire arrangement portion 183 are provided on the rear surface portion 50c of the heat insulation box 50. The fixing portions 182a and 182b have a convex shape that bulges a part of the back surface 50c of the outer case 51 toward the back surface side. Thus, the fixing portions 182a and 182b are also referred to as convex portions. The fixing portions 182a and 182b extend in the up-down direction along the extending direction of the power supply line 71 in a positional relationship substantially parallel to each other.

The wire arrangement portion 183 is located between the fixing portion 182a and the fixing portion 182b. The wire arrangement portion 183 is located between the fixing portions 182a and 182b having a shape protruding toward the rear surface side, and thus has a shape recessed with respect to the fixing portions 182a and 182b (see fig. 11). A power line 71 is disposed in the recess.

The attachment member 181 is attached to the fixing portion 182a and the fixing portion 182b so as to cover the wire arrangement portion 183 from the back side. The mounting member 181 is provided with a plurality of holes into which the screws 73 are inserted. Further, screw fixing holes 173a (see fig. 7) are provided in the fixing portions 182a and 182b at positions corresponding to the holes provided in the mounting member 181. Further, screw receiving portions 75 and 75 (see fig. 11) are provided inside (on the insulating layer 53 side) the respective fixing portions 82a and 82b. Since the screw 73 attached to the heat insulating box 50 is located at the convex portions of the fixing portions 182a and 182b, the screw 73 can be prevented from contacting the vacuum heat insulating material 55 disposed along the rear surface portion 50c.

The upper portion of the mounting member 181 is an upper cover 184 that covers the outlet 64 of the electrical component unit 60 from above. With this configuration, the outlet 64 of the electric unit 60 can be completely covered, and thus, the liquid such as water can be prevented from entering the electric unit 60 from the outlet 64.

As described above, in the present embodiment, the mounting member 181 is fixed to the heat insulation box 50 by inserting the screw 73 into the convex fixing portion 182a and the fixing portion 182b formed on the rear surface portion 50c. Therefore, in the configuration in which the vacuum heat insulating material 55 is disposed on the rear surface side of the heat insulating layer 53 in the heat insulating box 50, the cover member 172 for protecting the power supply line 71 can be disposed without damaging the vacuum heat insulating material 55.

[ third embodiment ]

Next, a third embodiment of the present invention will be described. In the third embodiment, a refrigerator in which a vacuum heat insulating material is provided in a heat insulating box 50 is described as an example, as in the second embodiment. In the refrigerator 1 according to the present embodiment, the structure of a cover member covering a power cord is different from that of the first embodiment. The cover member may have substantially the same structure as that of the first embodiment.

Fig. 12 shows an appearance of the back side of the refrigerator 1 according to the present embodiment. Fig. 13 shows the periphery of the cover member 272 on the back side of the refrigerator 1 in an enlarged manner. Fig. 14 shows a structure of an upper portion of the back surface side of the refrigerator 1. Fig. 15 shows a sectional configuration of an A-A line portion of the back surface portion of the refrigerator 1 shown in fig. 14. Fig. 16 shows a cross-sectional configuration of a C-C line portion of the back surface portion of the refrigerator 1 shown in fig. 14.

The refrigerator 1 is mainly composed of a heat insulating box (main body) 50 and various doors (not shown). The heat insulating box 50 has a heat insulating structure for insulating each storage compartment from the surroundings. The heat insulating box 50 mainly includes an outer box 51, an inner box 52, and a heat insulating layer 53. The heat insulating layer 53 is made of, for example, a foamed heat insulating material and a vacuum heat insulating material (VIP) 55.

An electric unit 60 is provided on the rear side of the upper surface portion 50a of the heat insulating box 50. As in the first embodiment, the electric component 60 includes an electric substrate 61, a lower case member 62, an upper case member 63, and the like (see fig. 25). As in the first embodiment, the power cord 71 extends from the outlets 64 on the rear sides of the lower case member 62 and the upper case member 63, and extends downward along the rear surface 50c of the heat insulation box 50. In fig. 12 and the like, the lower portion of the power line 71 is not illustrated.

A portion of the power cord 71 extending from the outlet 64 of the electrical component unit 60 is covered with a cover member 272. The cover member 272 is fixed to the heat insulating box 50. Fig. 12 and 13 show a state before the cover member 272 is attached to the back surface 50c of the refrigerator 1. By providing such a cover member 272, the power supply line 71 extending downward from the electric unit 60 can be protected.

As in the first embodiment, the cover member 272 covers at least a part of the horizontal extension portion 71a of the power line 71 and the vertical extension portion 71b of the power line 71 continuous from the horizontal extension portion 71a (see fig. 15).

The cover member 272 mainly includes a wire arrangement portion 281 and fixing portions 282a and 282b. The cover member 272 is obtained by molding a metal material, a resin material, or the like into a predetermined shape, for example.

As shown in fig. 15 and 16, in a state where the cover member 272 is attached to the refrigerator 1, the wire arrangement portion 281 has a space extending in the up-down direction inside. A power supply line 71 is disposed in the space.

The fixing portions 282a and 282b are provided in a flange shape on the outer periphery of the wire arrangement portion 281. In a state where the cover member 272 is attached to the refrigerator 1, the fixing portions 282a and 282b are in contact with the rear surface portion 50c of the heat insulation box 50. The fixing portion 282a is located on the left side of the line arrangement portion 281 as viewed from the back side of the refrigerator 1. The fixing portion 282b is located on the right side of the line arrangement portion 281 as viewed from the back side of the refrigerator 1.

Each of the fixing portions 282a and 282b is provided with a plurality of insertion claws 283a and 283b formed by cutting a part thereof. For example, 2 insertion claws 283a and 283a are provided in the fixed portion 282a, and 2 insertion claws 283b and 283b are provided in the fixed portion 282b. Each of the insertion claws 283a and 283b has a face portion along the rear face portion 50c of the heat insulation box 50. Each of the insertion claws 283a and 283b is inserted into an insertion hole 274 provided in the rear surface portion 50c of the heat insulation box 50.

A plurality of insertion holes 274 are provided in the rear surface 50c of the heat insulating box 50 at positions corresponding to the insertion claws 283a and 283b. In the present embodiment, 4 insertion holes 274 are provided. The insertion hole 274 has a convex shape (see fig. 16) that bulges a part of the rear surface 50c of the outer case 51 toward the rear surface side. Therefore, the insertion hole 274 is also referred to as a convex portion.

The upper portion of the cover member 272 becomes an upper cover 284 that covers the outlet 64 of the electrical component unit 60 from above. With this configuration, the outlet 64 of the electric unit 60 can be completely covered, and thus, the liquid such as water can be prevented from entering the electric unit 60 from the outlet 64.

A flange portion 285 is provided around the upper cover portion 284. The flange 285 is formed to be continuous from the fixing portions 282a and 282b. The flange portion 285 is provided with screw fixing holes 273a into which screws 73 are inserted.

In the present embodiment, the lid member 272 is attached to the heat insulation box 50 by inserting the insertion claws 283a and 283b of the lid member 272 into the insertion hole 274 provided in the rear surface portion 50c of the heat insulation box 50 from above. Further, by inserting the screw 73 into the screw fixing hole 273a provided in the flange portion 285, the cover member 272 can be fixed more reliably.

As described above, in the present embodiment, the lid member 272 is fixed to the heat insulation box 50 by inserting the insertion claws 283a and 283b of the lid member 272 into the insertion hole 274 formed in the rear surface portion 50c. Therefore, in the configuration in which the vacuum heat insulating material 55 is disposed on the rear surface side of the heat insulating layer 53 in the heat insulating box 50, the cover member 272 for protecting the power supply line 71 can be disposed without damaging the vacuum heat insulating material 55.

In the present embodiment, the cover member 272 can be attached to the rear surface 50c of the heat insulating box 50 without using screws. Therefore, the possibility of damaging the vacuum heat insulating material 55 in the heat insulating box 50 can be further reduced. Further, by attaching the tape so as to cover the insertion holes 274 from the heat insulating layer 53 side, leakage of the foamed heat insulating material filled in the heat insulating box 50 from the insertion holes 274 can be suppressed.

[ fourth embodiment ]

Next, a fourth embodiment of the present invention will be described. In the fourth embodiment, a description will be given of a configuration in which a cover member is attached to a handle portion forming member provided in the refrigerator 1. In the refrigerator 1 according to the present embodiment, the configuration of the handle portion and the cover member is different from the first embodiment. The other configurations may be substantially the same as those of the first embodiment.

Fig. 17 shows an appearance of the back side of the refrigerator 1 according to the present embodiment. Fig. 18 shows a structure of the back surface side of the refrigerator 1 with the attachment member 381 removed. Fig. 19 shows a structure of a vertical section of an upper portion of the back surface side of the refrigerator 1 shown in fig. 17. Fig. 19 is a sectional view corresponding to the position of the line A-A of fig. 3. Fig. 20 shows a configuration of a cross section of a rear side upper portion of the refrigerator 1 shown in fig. 17. Fig. 20 is a sectional view corresponding to the position of the C-C line portion of fig. 3.

The refrigerator 1 is mainly composed of a heat insulating box (main body) 50 and various doors (not shown). The heat insulating box 50 has a heat insulating structure for insulating each storage compartment from the surroundings. The heat insulating box 50 mainly includes an outer box 51, an inner box 52, and a heat insulating layer 53. The heat insulating layer 53 is made of, for example, a foamed heat insulating material, a vacuum heat insulating material (VIP) 55, or the like.

An electric unit 60 is provided on the rear side of the upper surface portion 50a of the heat insulating box 50. As in the first embodiment, the electric component 60 includes an electric substrate 61, a lower case member 62, an upper case member 63, and the like (see fig. 25). As in the first embodiment, the power cord 71 extends from the outlets 64 on the rear sides of the lower case member 62 and the upper case member 63, and extends downward along the rear surface 50c of the heat insulation box 50. In fig. 17 and the like, illustration of a lower portion of the power supply line 71 is omitted.

A pair of handle portions 31a and 31b are provided at left and right corner portions above the rear surface side of the heat insulating box 50. The pair of handle portions 31a and 31b have a laterally symmetrical structure. The handle portion 31a is located on the left side (right side viewed from the back side of the refrigerator 1) as viewed from the front side of the refrigerator 1. The handle portion 31b is located on the right side (on the left side as viewed from the back side of the refrigerator 1) as viewed from the front side of the refrigerator 1.

In the above embodiment, the pair of handle portions 31a and 31b are formed of different members. In contrast, in the present embodiment, the pair of handle portions 31a and 31b is constituted by one handle portion forming member 330.

The handle forming member 330 extends in the left-right direction along the upper end of the rear surface portion 50c of the heat insulating box 50. The handle portion forming member 330 is obtained by molding a resin material into a predetermined shape, for example. As shown in fig. 19, the upper end of the handle forming member 330 is connected to the rear end of the upper surface 50a of the outer case 51. The lower end of the handle forming member 330 is connected to the upper end of the back surface 50c (back plate) of the outer case 51.

As shown in fig. 19 and the like, the outlet 64 of the electric unit 60 is located near the upper end portion of the handle portion forming member 330. Therefore, in the present embodiment, the cover member 372 covering the power cord 71 is attached to the handle portion forming member 330. Fig. 18 shows a state before the cover member 372 is attached to the handle portion forming member 330.

The cover member 372 covers a portion of the power cord 71 extending from the outlet 64 of the electrical unit 60. By providing such a cover member 372, the power supply line 71 extending downward from the electric unit 60 can be protected.

As in the first embodiment, the cover member 372 covers at least a part of the horizontal extension portion 71a of the power line 71 and the vertical extension portion 71b of the power line 71 continuous from the horizontal extension portion 71a (see fig. 19).

The cover member 372 is mainly composed of a mounting member 381 and a fixing portion 333 provided to the handle portion forming member 330.

The mounting member 381 is obtained by, for example, forming a plate-like member formed of a metal material, a resin material, or the like into a predetermined shape. The mounting member 381 is fixed to the handle portion forming member 330 by a plurality of screws 73 (4 screws 73 in the example shown in fig. 18). More specifically, the mounting member 381 is fixed to the fixing portion 333 provided to the handle portion forming member 330.

The fixing portion 333 is located at the center portion of the handle portion forming member 330 in the left-right direction, and extends in the up-down direction. The fixing portion 333 is provided with a wire arrangement portion 334 extending along the extending direction of the power supply wire 71. The power supply line 71 (see fig. 20) is arranged in the line arrangement unit 334.

Further, an upper portion of the mounting member 381 becomes an upper cover portion 384 covering the outlet 64 of the electric unit 60 from above. With this configuration, the outlet 64 of the electric unit 60 can be completely covered, and thus, the liquid such as water can be prevented from entering the electric unit 60 from the outlet 64.

As described above, in the present embodiment, the mounting member 381 for protecting the power cord 71 is mounted to the handle portion forming member 330 constituting the upper portion of the rear surface portion 50c of the heat insulation box 50. The handle portion forming member 330 is formed of a resin material or the like, and therefore can be formed into a desired shape more easily than the back plate of the outer case 51. Therefore, the fixing portion 333 for mounting the mounting member 381 can be more easily formed into a desired shape.

By fixing the mounting member 381 to the handle portion forming member 330 in this manner, the screw 73 for fixing the mounting member 381 can be configured not to enter the heat insulating layer 53.

[ fifth embodiment ]

Next, a fifth embodiment of the present invention will be described. In the fifth embodiment, a structure in which a cover member is attached to a handle portion forming member provided in the refrigerator 1 is described as in the fourth embodiment. Therefore, the following description will focus on points different from the fourth embodiment.

Fig. 21 shows an appearance of the back side of the refrigerator 1 according to the present embodiment. Fig. 22 shows a structure of an upper portion of the back surface side of the refrigerator 1. Fig. 23 shows a structure of the back surface side of the refrigerator 1 with the cover member 472 removed.

An electric unit 60 is provided on the rear side of the upper surface portion 50a of the heat insulating box 50. In the present embodiment, the electric unit 60 is disposed at a position slightly shifted to the right side when viewed from the front side of the refrigerator 1. That is, the electric unit 60 is disposed on the side closer to the handle portion 31b.

As in the first embodiment, the electric component 60 includes an electric substrate 61, a lower case member 62, an upper case member 63, and the like (see fig. 25). As in the first embodiment, the power cord 71 extends from the outlets 64 on the rear sides of the lower case member 62 and the upper case member 63, and extends downward along the rear surface 50c of the heat insulation box 50. In fig. 21 and the like, a lower portion of the power line 71 is not illustrated.

In the present embodiment, the outlet 64 of the power cord 71 is disposed near the rear-side corner of the lower case member 62 and the upper case member 63.

A pair of handle portions 31a and 31b are provided at left and right corner portions above the rear surface side of the heat insulating box 50. In the first embodiment, the pair of handle portions 31a and 31b have a laterally symmetrical structure, but in the present embodiment, the pair of handle portions 31a and 31b have a laterally asymmetrical structure. This is because the handle forming member 430 forming the handle 31b located on the left side (right side when viewed from the back side of the refrigerator 1) has a fixing portion 433 and the like for attaching the cover member 472 in addition to the handle 31b when viewed from the front side of the refrigerator 1 (see fig. 23).

That is, the handle portion forming member 430 includes the handle portion 31b, the fixing portion 433, the wire arrangement portion 434, and the like.

As shown in fig. 23, the outlet 64 of the electric unit 60 is located in the vicinity of the upper end portion of the wire arrangement portion 434 of the handle portion forming member 430. The line arrangement portion 434 extends in the extending direction of the power supply line 71. The power supply line 71 (see fig. 23) is arranged in the line arrangement unit 434.

The cover member 472 is fixed to the fixing portion 433 of the handle forming member 430 by a plurality of screws 73 (2 screws 73 in the example shown in fig. 23). Thereby, the wire arrangement portion 434 is covered with the cover member 472. By providing such a cover member 472, the power cord 71 extending downward from the electric unit 60 can be protected.

As described above, in the present embodiment, the cover member 472 for protecting the power cord 71 is attached to the handle forming member 430 provided at the upper corner portion of the rear surface portion 50c of the heat insulating box 50. The handle portion forming member 430 is formed of a resin material or the like, and therefore can be formed into a desired shape more easily than the back plate of the outer case 51. Therefore, the fixing portion 433 for mounting the cover member 472 and the wire arrangement portion 434 for arranging the power supply wire 71 can be more easily formed into a desired shape.

In this way, by fixing the cover member 472 to the handle portion forming member 430, the screw 73 for fixing the cover member 472 can be configured not to enter the heat insulating layer 53.
