When the camera mounting member 70 is mounted on the refrigerator compartment door 11, the connector at the front end of the harness 82 and the connector of the small camera 71 are connected in advance (see FIGS. 6 and 7). Then, by mounting the camera mounting member 70 on the determined arrangement position of the refrigerator compartment door 11, the small camera 71 can be mounted on the refrigerator compartment door 11.

<About attaching a glass panel to the refrigerator compartment door> In the refrigerator 1 of this embodiment, the glass panel 51 is removably attached to the refrigerator compartment door 11. Moreover, in the refrigerator 1 of this embodiment, the camera mounting member 70 is also removably attached to the refrigerator compartment door 11. Hereinafter, a method of attaching the glass panel 51 and the camera mounting member 70 to the main body portion of the refrigerator compartment door 11 will be described.

First, an outer shape of a main body portion of the refrigerator compartment door 11 including a front member 41 and a door back portion 31 is formed. The vacuum heat insulating material is attached to at least one of the front member 41 and the door back 31 before the refrigerator compartment door 11 is formed into an outer shape. Next, various materials of a foam insulation material are added to the space between the front member 41 and the door back 31. After adding various materials of the foam insulation material, the front member 41 and the door back portion 31 are quickly combined. Thereby, various materials are foamed in the space between the front member 41 and the door back 31 to form a heat insulation layer 25 of a foamed heat insulation material.

Then, a glass panel 51 is mounted on the front surface of the main body portion of the refrigerator compartment door 11. At this time, the glass panel 51 is arranged on the front member 41 of the refrigerator compartment door 11 so that the glass panel 51 slides from the open end side of the refrigerator compartment door 11. Then, the lower end portion of the glass panel 51 is fitted into the holding portion 43 provided on the bottom surface portion 41 d of the front member 41. Further, the right end portion (the hinge-side end portion) of the glass panel 51 is fitted into the holding portion 42 provided on the side wall 41 a of the front member 41.

When the lower end portion and the right end portion of the glass panel are fitted into the holding portions 43 and 42, the side wall 41 b of the front member 41 is covered by the side member 52 at the left end portion (open end portion) of the glass panel 51. Then, the screw holes 55 a of the joint portion 55 provided at the end of the side member 52 are arranged so as to correspond to the screw holes 38 a formed in the side wall 41 b. The upper protrusion 53 provided above the rear surface of the glass panel 51 is supported by a support portion 44 provided on the upper surface portion 41 c of the front member 41.

In this way, in this embodiment, the side member 52 (first frame member) provided on the left end portion of the glass panel 51 and the upper protrusion 53 (first frame member) provided near the upper end portion correspond to the front member 41 Whose ends snap into place. Here, “engagement” means that the constituent members of the front member 41 and the constituent members (specifically, the first frame member) of the glass panel 51 are engaged with each other, and the glass panel 51 is supported or connected to the front member 41.

Next, the camera mounting member 70 is mounted on the main body portion of the refrigerator compartment door 11. At this time, as shown in FIG. 6 or FIG. 7, the camera is mounted so as to cover the side of the protruding wall 32 b of the door back 31 in a state where the small camera 71 provided inside the camera mounting member 70 is connected to the wire harness 82. Component 70. The screw holes 72 of the camera mounting member 70 are arranged so as to correspond to the screw holes 55 a of the joint portion 55 and the screw holes 38 a of the side wall 41 b.

Thereafter, the bolt 65 is inserted into each of the screw holes 72, 55a, and 38a. Each screw hole is formed in the groove part 21a (refer FIG. 3) in which the door gasket 21 is arrange | positioned. Finally, a door gasket 21 is installed on the refrigerator compartment door 11 so as to cover the screw holes.

The refrigerator compartment door 11 is assembled as described above.

<About the arrangement of the wiring harness for camera connection> Next, the internal structure of the refrigerator compartment door 11 which forms the wiring harness storage part 80 is demonstrated with reference to FIG. 13 and FIG. Fig. 13 is a cross-sectional view showing a configuration of a cut surface of a portion A-A shown in Fig. 2. Fig. 14 is a cross-sectional view showing a configuration of a part (open end side) of a cut surface of a B-B line portion shown in Fig. 3.

The outer shape of the main body portion of the refrigerator compartment door 11 is formed by a front member 41 and a door back portion 31 arranged to face the front member 41. A heat insulation layer 25 is formed in a space between the front member 41 and the door back 31. A door gasket 21 is provided on the side of the refrigerator compartment door 11 that faces the inside of the refrigerator 1 to improve the airtightness of the compartment when the refrigerator compartment door 11 is closed. A camera mounting member 70 is attached to the protruding wall 32 b on the open end side of the door back 31. A small camera 71 is provided inside the camera mounting member 70. The small camera 71 is connected to the display panel 50 via a camera harness 82.

The wire harness 82 enters into the heat insulation layer 25 from the front surface side of the front member 41 (see FIGS. 9 and 10). Further, the end of the camera connection side of the wire harness 82 is exposed from the heat insulation layer 25 to the outside of the box inner side of the door pad 21. That is, when the heat-insulating layer 25 is formed (for example, when the urethane is foamed), the end portion of the camera connection side of the wire harness 82 is housed inside the box (specifically, the back surface portion 38 of the front member 41 and The harness accommodating portion 80 of the nearby side wall 41b). When the camera mounting member 70 is installed after the heat insulation layer 25 is formed, the end of the camera connection side of the wire harness 82 is taken out from the wire harness accommodating part 80 and connected to the small camera 71 at the inner side of the box than the door gasket 21.

In addition, the other end portion (the end portion on the display panel connection side) of the harness 82 is exposed to the outside of the heat insulation layer 25 on the front side of the front member 41 (see FIG. 9).

A glass panel 51 is disposed on the front side of the front member 41. The glass panel 51 and the camera mounting member 70 are fixed to the main body portion of the refrigerator compartment door 11 (the screw hole 38 a of the front member 41 in this embodiment) by the same fixing member (specifically, the bolt 65).

In addition, a portion where a screw hole is formed in each of the constituent members (specifically, the side wall 41b of the front member 41, the joint portion 55 of the glass panel 51, and the end portion 70e of the camera mounting member 70) becomes a refrigerator door. The shape of the open end of the 11 side is slightly recessed inside. Thereby, a groove portion 21a for arranging a gasket is formed at a portion where the screw hole is formed. The door gasket 21 is fitted into the groove portion 21a.

Further, as shown in FIG. 14, convex portions 28 are formed on side surfaces on both sides of the groove portion 21 a. The door gasket 21 fitted into the groove portion 21a is notched. When the door gasket 21 is fitted into the groove portion 21 a, the door gasket 21 is mounted so that the convex portion 28 is located in the cutout. This can suppress the positional shift of the door gasket 21.

One of the side walls forming the groove portion 21 a is formed by the joint portion 55 of the glass panel 51, and the other side wall is formed by the end portion 70 e of the camera mounting member 70. Also, the convex portion 28 is similarly provided on each of the joint portion 55 and the end portion 70e. Thereby, the inner member (camera mounting member 70) of the box sandwiching the door gasket 21 and the outer member (glass panel 51) of the box are separate members, so it is possible to suppress heat leakage inside and outside the box caused by the heat conduction of the member itself . Therefore, the door gasket 21 can be used to maintain the heat insulation performance inside and outside the box.

(Summary) As described above, the refrigerator compartment door 11 of the refrigerator 1 of the present embodiment includes the compact camera 71 as an example of the electronic components. The small camera 71 is connected to the display panel 50 via a camera harness 82. Thereby, power is supplied from the display panel 50 to the small camera 71, and data of an image captured by the small camera 71 is transmitted to the display panel 50.

In addition, a wire harness 82 for camera connection enters the heat insulation layer 25 from the front surface side of the front member 41. Further, the end of the camera connection side of the wire harness 82 is exposed from the heat insulation layer 25 to the outside of the front member 41 (specifically, the wire harness accommodating part 80) on the inner side of the box than the door gasket 21.

According to the above configuration, the wire harness 82 connected to the small camera 71 for shooting in the box is pulled out from the heat insulation layer 25 to the inside of the box closer to the door pad 21 and can be placed closer to the inside of the box than the door pad 21. The connection with the small camera 71 is performed here. Therefore, when the camera mounting member 70 is mounted on the main body portion of the refrigerator compartment door 11, the connection portion of the wire harness 82 and the small camera 71 or the space for storing the wire harness 82 connected to the small camera 71 is the body portion of the refrigerator compartment door 11. The outside is closer to the inside of the box than the door pad 21. That is, since the space for connecting or accommodating the wire harness 82 is provided in a part of the refrigerating room space, it can be guided from the front side of the front member 41 to the inside of the box without reducing the heat insulation performance in the box due to the connection and storage of the wire harness 82. .

In addition, a wire harness 82 for a small camera 71 disposed inside the box can be provided without going through the door back portion 31. Therefore, it is not necessary to pass the wire harness 82 through the door back portion 31 before the door back portion 31 is fitted into the front member 41. Thereby, the formation of the main body part of the refrigerator compartment door 11 becomes easy. In addition, it is not necessary to make the harness 82 too long, and it is possible to suppress a decrease in the heat insulation performance of the refrigerator compartment door 11.

Therefore, the small-sized camera 71 can be connected to the wire harness 82 without reducing the heat insulation layer 25 between the front member 41 and the door back 31. Therefore, it is possible to suppress a decrease in the heat insulation performance caused by installing the small-sized camera 71 on the refrigerator compartment door 11. In addition, since the protruding wall 32b having the heat insulation layer 25 is located between the periphery of the small camera 71 and the inside of the door back 31, it is possible to suppress the occurrence of condensation that may be caused by the temperature difference between the periphery of the small camera 71 and the inside of the box.

Further, as in this embodiment, by mounting the camera mounting member 70 on the outer side surface of the protruding wall 32b of the door back 31, the small camera 71 can be arranged at the rear end of the refrigerator compartment door 11. Therefore, when the inside of the box is photographed by using the small camera 71, the possibility of blind spots formed by the components of the refrigerator compartment door 11 can be reduced.

The electronic components provided in the refrigerator compartment door 11 are not limited to small cameras. As an electronic component other than a small camera, an operation panel, an ion supply unit, and the like may be provided inside the box of the refrigerator compartment door 11.
