(Composition of the refrigerator compartment door)

Next, a more specific configuration of the refrigerator compartment door 11 included in the refrigerator 1 will be described with reference to FIGS. 2 to 8.

The back side of the refrigerator compartment door 11 is shown enlarged in FIG. 2. 3 and 4 show a configuration of a front member (front side member) 41 constituting the refrigerator compartment door 11. FIG. 3 shows the configuration of the back (rear) side of the front member 41. In addition, FIG. 4 shows the configuration of the front (front) side of the front member 41. 5 and 6 show a configuration of a door back (back side member) 31 constituting the refrigerator compartment door 11. 5 and 6 show the configuration of the front side (the side facing the front member 41) of the door back 31. 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 back side of the refrigerator compartment door 11 is formed by a door back 31. The door back 31 is formed of, for example, a plate-like member made of resin. A plurality of storage bags 61, 62, 63 are attached to the door back 31, and the plurality of storage bags 61, 62, 63 are arranged on the back surface of the refrigerator compartment door 11 so as to extend in the left-right direction. A projection wall (projection) 32 is formed on the back side of the refrigerator compartment door 11 so as to follow the outer periphery of the door. The protruding wall 32 is also called a bank, a flange, or the like.

An intermediate cover 21 is attached to the open end portion of the refrigerator compartment door 11. A heat dissipation tube for preventing frost may be disposed inside the intermediate cover 21. In addition, a side cover 23 is attached to the right end portion (the end opposite to the open end portion) of the refrigerator compartment door 11. A hinge portion 22 is provided inside the side cover 23 (see FIG. 3).

In addition, three small cameras 70 (70a, 70b, 70c) are provided at the front end portion of the protruding wall 32 at the open end portion of the refrigerator compartment door 11. The compact camera 70 is configured by, for example, a CCD camera. The top small camera 70a of the three small cameras 70 is located above the storage bag 61, the center small camera 70 is located between the storage bag 61 and the storage bag 62, and the bottom small camera 70c is located between the storage bag 62 and the storage bag 63 . In this way, by providing a plurality of small cameras 70 each having a different height position, it is possible to reduce the dead space in the refrigerating room that cannot be captured.

Next, each constituent member constituting the refrigerator compartment door 11 will be described. The main constituent members of the refrigerator compartment door 11 include a front member 41, a door back 31, and a heat insulation layer 44 (see FIG. 8). The front member 41 is located on the front side of the refrigerator compartment door 11 and constitutes the front surface of the refrigerator compartment door 11. The door back 31 and the front member 41 are arranged to face each other, and constitute the back side of the refrigerator compartment door 11. A door back 31 is fitted into the back surface of the front member 41, and the side surface is covered with the intermediate cover 21 and the side cover 23, thereby forming the outer shape of the refrigerator compartment door 11. The heat insulation 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, a foamed heat-insulating material, or the like. The vacuum insulation material is a sheet-shaped or plate-shaped insulation material. The foamed heat insulating material contains, for example, foamed polyurethane (also referred to as rigid polyurethane foam).

The vacuum heat-insulating material is partially arranged inside the casing and each door of the refrigerator. The vacuum insulation material is formed by covering a core material having fine voids such as glass wool or silicon dioxide powder with an airtight outer covering material (bag-like body, such as a laminated film), and the inside of the outer covering material is decompressed and sealed. . The vacuum insulation material maintains a high degree of vacuum in its internal space, and it is only possible to reduce the heat transferred in the gas phase, thereby achieving a high heat insulation effect. As a material constituting the vacuum heat insulating material, a publicly known person can be used.

Therefore, in a refrigerator, it is preferable to arrange a vacuum heat insulating material especially where high heat insulation is required. For example, in the refrigerator 1 and the refrigerator compartment door 11, it is preferable to arrange a vacuum heat insulating material at a position facing the display panel 50. Thereby, the heat generated from the display panel 50 can be more reliably blocked, 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 two main raw materials, a foaming agent, and a foaming agent, and simultaneously causing a foaming reaction and a resinization reaction. After the reaction, the foamed polyurethane has rigidity.

As shown in FIG. 4, the front side of the front member 41 is comprised from the top by the glass panel installation surface 42a, the display panel installation part 42c, and the glass panel installation surface 42b in this order. The glass panel installation surface 42a and 42b is fitted with a glass panel. The display panel installation portion 42c located at the center portion is formed at a position recessed from the glass panel installation surfaces 42a and 42b. A display panel 50 is attached to the display panel installation portion 42c.

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

As shown in FIG. 3, on the back side of the front member 41, the wire harness 74 extends along the open end portion (on the middle cover 21 side). The wiring harness 74 extends from the display panel installation portion 42c toward the installation portions of the respective small cameras 70a, 70b, and 70c. As shown in FIG. 3, a connector 72 is attached to a front end portion of each harness 74. The connector 72 is connected to the wiring 71 (see FIG. 8) on the small camera 70 side. This makes it possible to supply power and the like to the compact camera 70. In addition, the image data captured by the small camera 70 can be transmitted to the control board of the display panel 50.

In addition, on the back side of the front member 41, a connector protection member 43 is disposed at each connector. In the example shown in FIG. 3, four connector protection members 43 are arranged along the open end portion (on the middle cover 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 front end portion of the harness 74 including the connector 72. The space P is obtained by forming a recessed portion on the surface of the connector protection member 43. As will be described later, in the assembled state of the refrigerator compartment door 11, the connector 72 is covered by the connector protection member 43 and the second connector protection member 33 (electronic component installation portion) provided on the door back 31 side. State (see Fig. 8). That is, the 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 insulation performance of the refrigerator compartment door 11. In addition, in order to easily form the space P, it is preferable that the space P is formed of a material that is softer than the main constituent element of the heat-insulating layer 44, that is, foamed polyurethane. In the present embodiment, the connector protection member 43 is formed of expanded polystyrene (second heat insulating material).

Expanded polystyrene is formed as polystyrene containing bubbles. Expanded polystyrene is softer than foamed polyurethane and can be easily processed into a desired shape. Therefore, in the refrigerator 1 of the present embodiment, the expanded polystyrene is suitably used as the 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. 5 and 6 show a part of the configuration of the front side (the side facing the front member 41) of the door back 31. Specifically, FIGS. 5 and 6 show a detailed configuration of the open end portion side 31 a (the middle cover 21 side) where the wire harness 74 is arranged.

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

The second connector protection members 33 are arranged at positions corresponding to the connector protection members 43 on the front member 41 side, respectively. Therefore, in the example shown in FIG. 5, the second connector protection member 33 corresponds to the connector protection member 43 on the front member 41 side, and four are arranged along the open end portion (on the middle cover 21 side). However, the number of the second connector protection members 33 is not limited to four, and may be appropriately determined depending on the number of connectors.

A space P is provided in the second connector protection member 33. The space P is obtained by forming a recessed portion on the surface of the second connector protection member 33. In the assembled state of the refrigerator compartment door 11, the space P formed in the second connector protection member 33 communicates with the space P formed in the front member 41. In addition, the front end portion of the wire harness 74 including the connector 72 is housed in the space P. Furthermore, small-scale photography is installed In the state of the camera 70, the wiring 71 on the small camera 70 side connected through the connector 72 is also arranged in the space P.

In this embodiment, as shown in FIG. 6, the second connector protection members 33 are arranged along the arrangement positions of the protruding walls 32. This is because a small camera 70 corresponding to an electronic component is provided at the front end of the protruding wall 32. Therefore, the space P formed in the second connector protection member 33 penetrates the inside of the protruding wall 32. The space P formed in the second connector protection member 33 corresponds to an electronic component installation portion on which electronic components are mounted.

The second connector protection member 33 is preferably formed of a heat insulating material in order to maintain the heat insulation performance of the refrigerator compartment door 11. In addition, in order to easily form the space P, it is preferable that the space P is formed of a material that is softer than the main constituent element of the heat-insulating layer 44, that is, foamed polyurethane. In the present embodiment, the second connector protection member 33 is formed of expanded polystyrene (second heat insulating material) similarly to the connector protection member 43.

In a state where the heat-insulating layer 44 is provided inside, the above-mentioned front member 41 and the door back 31 are arranged to face each other to constitute the refrigerator compartment door 11 shown in FIG. 7.

FIG. 8 shows the internal structure of the protruding wall 32 in which the compact camera 70 is provided. In a state where the front member 41 and the door back 31 face each other and the refrigerator compartment door 11 is assembled, the connector protection member 43 and the second connector protection member 33 are overlapped in the front-rear direction. Further, each space P formed in each of the protection members 43 and 33 communicates with each other to form a single space P. In this space P, a wiring 71, a connector 72, and a wiring harness 74 electrically connected to the small camera 70 are arranged.

(About manufacturing method of refrigerator compartment door)

Next, a method for manufacturing the refrigerator compartment door 11 according to an aspect of the present invention will be described. As described above, the refrigerator compartment door 11 includes electronic components such as the compact camera 70. Such a manufacturing method of the refrigerator compartment door 11 includes at least a front member 41 having a connector protection member 43 and a door back 31 having an electronic component installation portion. A step of arranging; a step of foaming a raw material of a foamable heat-insulating material between the front member 41 and the door back 31 to form a heat-insulating layer; step.

In the manufacturing method described above, a space P is formed in the connector protection member 43 in which the connector 72 and the wiring 71 connected to the electronic component are arranged. In addition, 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.

Hereinafter, a more specific manufacturing method will be described with reference to FIGS. 9 and 10. 9 (a) and 9 (b) 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 inside the dotted frame shown in FIG. 6. 10 (a) and 10 (b) 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 inside the dotted frame shown in FIG. 3.

As shown in FIG. 9 (a), the door back 31 includes second connector protection members 33 a and 33 b. 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. 10 (a), the front member 41 includes connector protection members 43 a and 43 b. A space P1 is formed in the connector protection member 43a, and a space P2 is formed in the connector protection member 43b. In addition, the space P1 and the space P2 house the front end portion of the wire harness 74 having the connector 72.

In addition, before the step of arranging the front member 41 and the door back 31 to face each other, as shown in FIG. 9 (b), a sheet member 81 is stuck on the surfaces of the second connector protection members 33a and 33b to cover the space P1 and the space P2. Similarly, as shown in FIG. 10 (b), a sheet member 82 is stuck on 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, adhesive tapes.

Next, a raw material of foamed polyurethane is added to either of the front member 41 and the door back 31. Here, the raw material of the foamed polyurethane is a mixed medium of two main raw materials, a foaming agent, a foaming agent, and the like.

After that, 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 face each other. In this way, the front member 41 and the door back 31 are arranged.

During this period, the raw material of the foamed polyurethane existing between the front member 41 and the door back 31 simultaneously causes a foaming reaction and a resinization reaction to form a resin foam, that is, a rigid foamed polyurethane. Thereby, the heat insulation layer 44 is formed.

In the reaction for generating the foamed polyurethane, each of the spaces P1 and P2 is covered by the sheet member 81 or 82. Therefore, in a case where the space P on the connector protection member 43 side and the space P on the second connector protection member 33 side are slightly offset from each other, or when a small gap is formed, it is possible to more surely prevent the foamed polyurethane from entering the space P.

Thereafter, a small camera 70 is provided at the front end of the protruding wall 32 of the door back 31. Specifically, a part of the portion of the door back 31 where the space P is formed (that is, the electronic component installation portion) is cut out. Next, the chip members 81 and 82 are pulled into the space P from the formed notch portion. Thereby, the connector 72 accommodated in the space P accommodated in the connector protection member 43 side can be drawn out. In addition, the wiring 71 of the small camera 70 is passed through a cutout portion formed in the door back 31. Next, the wiring 71 is connected to the connector 72, thereby completing the mounting of the small camera 70 (see FIG. 8).

In addition, the notch portion may be formed in the door back 31 in advance, and an electronic component provided on the door back 31 may be used as the notch portion. In this case, the connector protection member 33 surrounds the periphery of the notch so that the foamed polyurethane does not enter the notch. Alternatively, a sealing member such as an adhesive tape is adhered to the cutout portion so that the foamed polyurethane does not leak out of the door back 31 from the cutout portion, and then the foamed polyurethane is formed to form the heat insulation layer 44.

(to sum up)

According to the configuration of this 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 from contact with the foamed polyurethane, which is a main component of the heat-insulating layer 44. That is, the connector 72 can be prevented from being eroded by the foamed polyurethane foamed when the refrigerator compartment door 11 is manufactured, and buried in the foamed polyurethane.

In addition, an electronic component mounting section on which electronic components such as a camera are mounted is provided on the door back 31 of the refrigerator compartment door 11, and this electronic component mounting section 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 components can be connected to the connector 72 from the electronic component installation portion of the door back 31. Thereby, the electronic component can be easily installed on the back side of the refrigerator compartment door 11.

In the refrigerator compartment door 11 of the present embodiment, the connector protection member 43 is formed of a second heat-insulating material (for example, expanded polystyrene) different from the foamed polyurethane. Therefore, it is possible to suppress a decrease in the heat insulation performance of the refrigerator door 11.

Moreover, in the refrigerator compartment door 11 of this embodiment, the second connector protection member 33 is provided in the electronic component installation portion of the door back 31. The second connector protection member 33 together with the connector protection member 43 forms a space P in which the connector 72 is arranged. Thereby, the space for arranging the connector 72 can be more ensured. In addition, by bringing the surface of the connector protection member 43 into contact with the surface of the second connector protection member 33, the possibility of the foamed polyurethane entering the space P in which the connector 72 and the like are accommodated can be reduced.
