<Refrigerator compartment door configuration>
Next, a more specific configuration of the refrigerator compartment door 11 provided in the refrigerator 1 will be described with reference to FIGS.

  FIG. 2 is an enlarged view of the rear side of the refrigerator compartment door 11. 3 and 4 show the configuration of the front member (front member) 41 that forms the refrigerator compartment door 11. FIG. 3 shows the configuration of the back surface (back surface) of the front member 41. FIG. 4 shows the configuration of the front (front) side of the front member 41. FIGS. 5 and 6 show the configuration of the door back (back side member) 31 constituting the refrigerator compartment door 11. 5 and 6 show the configuration of the front side of the door back 31 (the side facing the front member 41). FIG. 7 shows the configuration of the front side of the refrigerator compartment door 11 with the display panel 50 removed. FIG. 8 shows a cross-sectional configuration of the refrigerator compartment door 11 on the open end side (the end opposite to the end where the hinge is provided). The refrigerator compartment door 11 is opened and closed from the open end side.

  As shown in FIG. 2, the rear side of the refrigerator compartment door 11 is formed by a door back 31. The door back 31 is formed of, for example, a resin plate member. A plurality of storage pockets 61, 62, and 63 are attached to the door back 31 so as to extend in the left-right direction on the back surface of the refrigerator compartment door 11. A protruding wall (projection) 32 is formed on the rear side of the refrigerator compartment door 11 along the outer periphery of the door. The protruding wall 32 is also called a bank, a flange, or the like.

  A center cap 21 is attached to an open end of the refrigerator compartment door 11. A radiation pipe for preventing condensation may be arranged inside the center cap 21. Further, a side cap 23 is attached to a right end (an end opposite to the open end) of the refrigerator compartment door 11. A hinge portion 22 is provided inside the side cap 23 (see FIG. 3).

  Further, three small cameras 70 (70a, 70b, 70c) are provided at the distal end of the protruding wall 32 at the open end of the refrigerator compartment door 11. The small camera 70 is composed of, for example, a CCD camera. Of the three miniature cameras 70, the uppermost miniature camera 70a is located above the storage pocket 61, the middle miniature camera 70b is located between the storage pockets 61 and 62, and the lowermost miniature camera 70b is located between the storage pockets 61 and 62. The small camera 70c is located between the storage pocket 62 and the storage pocket 63. By providing a plurality of small cameras 70 arranged at different heights as described above, it is possible to reduce blind spots in the refrigerator compartment where images cannot be taken.

  Subsequently, each component constituting the refrigerator compartment door 11 will be described. The refrigerator compartment door 11 includes, as main components, a front member 41, a door back 31, and a heat insulating layer 44 (see FIG. 8). The front member 41 is located on the front side of the refrigerator compartment door 11 and forms the front of the refrigerator compartment door 11. The door back 31 is arranged to face the front member 41 and forms the rear side of the refrigerator compartment door 11. The outer shape of the refrigerator compartment door 11 is formed by fitting the door back 31 into the back surface of the front member 41 and covering the side surface with the center cap 21 and the side cap 23. Further, the heat insulating layer 44 is disposed between the front member 41 and the door back 31.

  The heat insulating layer 44 is made of, for example, a vacuum heat insulating material and a foam heat insulating material. The vacuum heat insulating material is a sheet-shaped or plate-shaped heat insulating material. The foamed heat insulating material includes, for example, foamed polyurethane (also called rigid urethane foam).

  The vacuum heat insulating material is partially disposed inside the refrigerator housing and each door. The vacuum heat insulating material is formed by covering a core material having fine voids, such as glass wool or silica powder, with a jacket material having a gas barrier property (a bag-like body, for example, a laminate film), and sealing the inside of the jacket material under reduced pressure. You. The vacuum heat insulating material can realize a high heat insulating effect by keeping the internal space at a high vacuum and minimizing the amount of heat transmitted through the gas phase. As a material constituting the vacuum heat insulating material, a conventionally known material can be used.

  Therefore, it is desirable to arrange a vacuum heat insulating material in a refrigerator where a particularly high heat insulating property is required. For example, in the refrigerator 1, it is preferable to dispose a vacuum heat insulating material at a position facing the display panel 50 in the refrigerator compartment door 11. Thereby, the heat generated from the display panel 50 can be more reliably shut off, and the heat insulation performance of the refrigerator compartment door 11 can be improved.

  The foamed polyurethane is a main constituent material of the heat insulating layer 44. Foamed polyurethane is a uniform resin foam obtained by mixing a catalyst, a foaming agent, a foaming agent, and the like with two kinds of main raw materials and simultaneously causing a foaming reaction and a resinizing reaction. After the completion of the reaction, the polyurethane foam has rigidity.

  As shown in FIG. 4, the front side of the front member 41 includes a glass panel installation surface 42a, a display panel installation portion 42c, and a glass panel installation surface 42b in order from the top. Glass panels are attached to the glass panel installation surfaces 42a and 42b. Further, the display panel installation portion 42c located at the center is formed at a position recessed from the glass panel installation surfaces 42a and 42b. The display panel 50 is attached to the display panel installation part 42c.

  Further, harnesses 74 and 75 pass through the display panel installation section 42c. More specifically, the harnesses 74 and 75 pass through the space between the display panel 50 and the display panel installation part 42c. The harness 74 is an aggregate of wiring connecting the control unit and the power supply unit or the display panel 50 provided in the main body of the refrigerator 1 to each of the small cameras 70. The harness 75 is an assembly of wires for connecting a control unit and a power supply unit provided in the main body of the refrigerator 1 to the display panel 50 or the small camera 70. FIG. 4 illustrates a part of the harness 75.

  As shown in FIG. 3, on the rear side of the front member 41, the harness 74 extends along the open end (the side of the center cap 21). The harness 74 extends from the display panel installation part 42c to the installation part of each of the small cameras 70a, 70b, 70c. As shown in FIG. 3, a connector 72 is attached to the tip of each harness 74. The connector 72 is connected to the wiring 71 (see FIG. 8) on the small camera 70 side. Thus, power or the like can be supplied to the small camera 70. Further, data of an image captured by the small camera 70 can be transmitted to the control board of the display panel 50.

  On the back side of the front member 41, a connector protection member 43 is disposed at a position where each connector is disposed. In the example shown in FIG. 3, four connector protection members 43 are arranged along the open end (center cap 21 side). However, the number of the connector protection members 43 is not limited to four. The number of connector protection members 43 may be determined according to the number of connectors.

  The connector protection member 43 is provided with a space P for accommodating the distal end portion of the harness 74 including the connector 72. The space P is obtained by forming a recess on the surface of the connector protection member 43. As will be described later, in a state where the refrigerator compartment door 11 is assembled, the connector 72 is surrounded by the connector protection member 43 and the second connector protection member 33 (electronic component installation part) provided on the door back 31 side. Is covered (see FIG. 8). That is, foamed polyurethane cannot enter the area where the connector 72 is arranged.

  The connector protection member 43 is preferably formed of a heat insulating material in order to maintain the heat insulating performance of the refrigerator compartment door 11. Further, in order to easily form the space P, it is preferable that the space P is formed of a material softer than the foamed polyurethane which is a main component of the heat insulating layer 44. In the present embodiment, the connector protection member 43 is formed of styrene foam (a second heat insulating material).

  Styrofoam is formed of polystyrene containing cells. Since Styrofoam is softer than foamed polyurethane, it can be easily formed into a desired shape. Therefore, in the refrigerator 1 of the present embodiment, styrene foam is suitably used as a material of the connector protection member 43 and the second connector protection member 33.

  Next, the door back 31 will be described with reference to FIGS. 5 and 6 show a part of the configuration of the front side of the door back 31 (the side facing the front member 41). Specifically, FIGS. 5 and 6 show a detailed configuration of the open end 31a (center cap 21 side) where the harness 74 is arranged.

  As shown in FIG. 5, the left end of the door back 31 is 31a, and the right end of the door back 31 is 31b. The left end 31a corresponds to an open end to which the center cap 21 is attached. In the present embodiment, a plurality of second connector protection members 33 are arranged along the left end 31a of the door back 31.

  The second connector protection members 33 are respectively arranged at positions corresponding to the connector protection members 43 of the front member 41. Therefore, in the example illustrated in FIG. 5, four second connector protection members 33 are arranged along the open end (the side of the center cap 21) corresponding to the connector protection member 43 on the front member 41 side. . However, the number of the second connector protection members 33 is not limited to four, and can be appropriately determined according to the number of connectors.

  A space P is provided in the second connector protection member 33. The space P is obtained by forming a recess on the surface of the second connector protection member 33. In a state where the refrigerator compartment door 11 is assembled, the space P formed in the second connector protection member 33 communicates with the space P formed in the front member 41 described above. The distal end portion of the harness 74 including the connector 72 is accommodated in the space P. Furthermore, when the small camera 70 is attached, the wiring 71 of the small camera 70 connected via the connector 72 is also arranged in the space P.

  In the present embodiment, as shown in FIG. 6, the second connector protection members 33 are respectively arranged along the arrangement positions of the protruding walls 32. This is because the small camera 70 corresponding to the electronic component is installed at the tip of the protruding wall 32. Therefore, the space P formed in the second connector protection member 33 passes through the inside of the protruding wall 32. The space P formed in the second connector protection member 33 corresponds to an electronic component installation part to which an electronic component is attached.

  The second connector protection member 33 is preferably formed of a heat insulating material in order to maintain the heat insulating performance of the refrigerator compartment door 11. Further, in order to easily form the space P, it is preferable that the space P is formed of a material softer than the foamed polyurethane which is a main component of the heat insulating layer 44. In the present embodiment, the second connector protection member 33 is made of Styrofoam (a second heat insulating material), like the connector protection member 43.

  With the heat insulating layer 44 inside, the above-described front member 41 and door back 31 are arranged to face each other, and the refrigerator compartment door 11 as shown in FIG. 7 is configured.

  FIG. 8 shows an internal configuration of the protruding wall 32 on which the small camera 70 is installed. In a state where the front member 41 and the door back 31 are arranged to face each other and the refrigerator compartment door 11 is assembled, the connector protection member 43 and the second connector protection member 33 overlap each other in the front-rear direction. The spaces P formed in the protection members 43 and 33 communicate with each other to form one space P. In this space P, a wiring 71, a connector 72, and a harness 74 that are electrically connected to the small camera 70 are arranged.

<About the manufacturing method of the refrigerator compartment door>
Subsequently, a method for manufacturing the refrigerator compartment door 11 according to one embodiment of the present invention will be described. As described above, the refrigerator compartment door 11 includes electronic components such as the small camera 70. Such a method of manufacturing the refrigerator compartment door 11 includes a step of arranging the front member 41 having the connector protection member 43 and the door back 31 having the electronic component installation portion in opposition to each other. The method includes at least a step of forming a heat insulating layer by foaming a raw material of the foamable heat insulating material, and a step of attaching an electronic component to an electronic component installation portion formed on the door back 31 side.

  In the above-described manufacturing method, the connector protection member 43 has a space P for arranging the connector 72 and the wiring 71 connected to the electronic component. In the step of arranging the front member 41 and the door back 31 to face each other, the front member 41 and the door back 31 are arranged so that the space formed in the connector protection member 43 and the electronic component installation portion overlap in the front-rear direction. I do.

  Hereinafter, a more specific manufacturing method will be described with reference to FIGS. FIGS. 9A and 9B show a part of the door back 31 before assembly. The area of the door back 31 shown in these figures corresponds to the area within the broken line frame shown in FIG. FIGS. 10A and 10B show a part of the front member 41 before assembly. The area of the front member 41 shown in these figures corresponds to the area within the broken line frame shown in FIG.

  As shown in FIG. 9A, the door back 31 is provided with second connector protection members 33a and 33b. A space P1 is formed in the second connector protection member 33a, and a space P2 is formed in the second connector protection member 33b.

  As shown in FIG. 10A, the front member 41 is provided with connector protection members 43a and 43b. A space P1 is formed in the connector protection member 43a, and a space P2 is formed in the connector protection member 43b. Note that the distal end portion of the harness 74 having the connector 72 is accommodated in the space P1 and the space P2.

  Prior to the step of disposing the front member 41 and the door back 31 to face each other, as shown in FIG. 9B, the surfaces of the second connector protection members 33a and 33b are covered so as to cover the spaces P1 and P2. The sheet member 81 is stuck on. Similarly, as shown in FIG. 10B, a sheet member 82 is attached to the surfaces of the connector protection members 43a and 43b so as to cover the space P1 and the space P2. The sheet members 81 and 82 are, for example, an adhesive tape or the like.

  Subsequently, a raw material of foamed polyurethane is added to one of the front member 41 and the door back 31. Here, the raw material of the foamed polyurethane is a mixture of two types of main raw materials, such as a catalyst, a foaming agent, and a foaming agent.

  Thereafter, the front member 41 and the door back 31 are arranged to face each other. Here, the space P1 of the connector protection member 43a and the space P1 of the second connector protection member 33a face each other, and the space P2 of the connector protection member 43b and the space P2 of the second connector protection member 33b. The front member 41 and the door back 31 are arranged to face each other.

  During this time, the raw material of the polyurethane foam present between the front member 41 and the door back 31 simultaneously causes a foaming reaction and a resinification reaction to form a hard foamed polyurethane which is a resin foam. Thereby, the heat insulating layer 44 is formed.

  During the reaction for producing the polyurethane foam, each of the spaces P1 and P2 is covered with the sheet member 81 or 82. Therefore, even when the space P on the connector protection member 43 side and the space P on the second connector protection member 33 side are slightly displaced from each other or when a slight gap is formed, the foamed polyurethane is kept in the space P. Can be suppressed more reliably.

  Thereafter, the small camera 70 is installed at the tip of the protruding wall 32 of the door back 31. Specifically, a portion of the door back 31 where the space P is formed (that is, the electronic component installation portion) is partially cut away. Then, the sheet member 81 and 82 are broken into the space P from the formed notch. Thus, the connector 72 housed in the space P on the connector protection member 43 side can be pulled out. In addition, the wiring 71 of the small camera 70 passes through the cutout formed in the door back 31. Then, by connecting the wiring 71 to the connector 72, the mounting of the small camera 70 is completed (see FIG. 8).

  Note that the notch may be formed in the door back 31 in advance, or an installation location of an electronic component installed in the door back 31 may be a notch. In such a case, the periphery of the notch is surrounded by the connector protection member 33 so that the polyurethane foam does not enter the notch. Alternatively, after attaching a sealing member such as an adhesive tape to the notch so that the foamed polyurethane does not leak out of the door back 31 from the notch, the foamed polyurethane is generated to form the heat insulating layer 44.

(Summary)
According to the configuration according to the present embodiment, the connector 72 can be arranged in the space P formed in the connector protection member 43. Therefore, when the refrigerator compartment door 11 is manufactured, the connector 72 can be protected so as not to come into contact with the polyurethane foam which is a main component of the heat insulating layer 44. That is, it is possible to prevent the connector 72 from being eroded by the foamed polyurethane that expands and expands during the manufacture of the refrigerator compartment door 11 and buried in the foamed polyurethane.

  The door back 31 of the refrigerator compartment door 11 is provided with an electronic component installation portion to which an electronic component such as a camera is attached, and this electronic component installation portion communicates with the space P of the connector protection member 43. . Therefore, after the assembly of the refrigerator compartment door 11 is completed, the electronic component can be connected to the connector 72 from the electronic component installation portion of the door back 31. Thereby, electronic components can be easily installed on the back side of the refrigerator compartment door 11.
