(The composition of the refrigerator 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 .

In FIG. 2, the rear side of the refrigerator compartment door 11 is enlarged and shown. 3 and 4 show the configuration of the front member (front side member) 41 constituting the refrigerator compartment door 11 . In FIG. 3, the structure of the back (rear) side of the front member 41 is shown. In addition, in FIG. 4, the structure of the front (front) side of the front member 41 is shown. 5 and 6 show the structure of the door back (rear side member) 31 constituting the refrigerator compartment door 11 . In FIGS. 5 and 6 , the configuration of the front side (the side facing the front member 41 ) of the door back 31 is shown. In FIG. 7, the structure of the front side of the refrigerator compartment door 11 with the display panel 50 removed is shown. In FIG. 8, the cross-sectional structure of the open end side (end part opposite to the end part provided with a hinge) of the refrigerator compartment door 11 is shown. Refrigerating 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 with a door back 31 . The door back 31 is formed of, for example, a resin-made plate-shaped member. A plurality of storage bags 61 , 62 , and 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. Moreover, the protrusion wall (protrusion part) 32 is formed in the back surface side of the refrigerator compartment door 11 so that it may follow the outer periphery of a door. The protruding wall 32 is also called a bank, a flange, or the like.

The intermediate cover 21 is attached to the open end part of the refrigerator compartment door 11. As shown in FIG. Heat radiation pipes for frost prevention may be disposed inside the intermediate cover 21 . Moreover, the side cover 23 is attached to the right end part (end part opposite to an open end part) of the refrigerator compartment door 11. As shown in FIG. 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 of the protruding wall 32 at the open end of the refrigerator compartment door 11. As shown in FIG. The compact camera 70 is constituted by, for example, a CCD camera or the like. Among the three small cameras 70, the uppermost small camera 70a is located above the storage bag 61, the central small camera 70 is located between the storage bag 61 and the storage bag 62, and the bottommost small camera 70c is located between the storage bag 62 and the storage bag 63 . In this manner, by providing a plurality of small cameras 70 arranged at different height positions, it is possible to reduce blind spots in the refrigerator compartment that cannot be photographed.

Next, each component constituting the refrigerator compartment door 11 will be described. The main constituent members of the refrigerator compartment door 11 include the front member 41, the door back 31, and the heat insulation layer 44 (refer FIG. 8). The front member 41 is located on the front side of the refrigerator compartment door 11 and constitutes the front of the refrigerator compartment door 11 . Door back 31 is arranged to face front member 41 , and constitutes the rear side of refrigerator compartment door 11 . The door back 31 is fitted into the back surface of the front member 41 , and the side surfaces are covered with the middle cover 21 and the side covers 23 , whereby the outer shape of the refrigerator compartment door 11 is formed. In addition, the heat insulating layer 44 is arranged between the front member 41 and the door back 31 .

The heat insulating layer 44 is comprised with a vacuum heat insulating material, a foam heat insulating material, etc., for example. The vacuum heat insulating material is a sheet-like or plate-like heat insulating material. The foamed heat insulating material includes, for example, foamed urethane (also called rigid urethane foam) and the like.

The vacuum heat insulating material is partially arranged inside the casing and each door of the refrigerator. Vacuum heat insulation materials are formed by covering a core material with fine gaps such as glass wool or silica powder with an airtight outer covering material (bag-like body, such as a laminated film), and decompressing and sealing the inside of the outer covering material. form. Vacuum heat insulation material keeps its internal space highly vacuum, only possible to reduce the heat transferred in the gas phase, thus achieving high heat insulation effect. A well-known thing can be used about the material which comprises a vacuum heat insulating material.

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

Foamed urethane is a main constituent material of the heat insulating layer 44 . Foaming polyurethane is a uniform resin foam obtained by mixing two main raw materials, a foaming agent, a foaming agent, etc., and causing a foaming reaction and a resinization reaction at the same time. The foamed polyurethane after the reaction is rigid.

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

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

In addition, as shown in FIG. 3 , on the back side of the front member 41 , the wire harness 74 extends along the open end portion (middle cover 21 side). The harness 74 extends from the display panel installation part 42c toward the installation part of each compact camera 70a, 70b, 70c. As shown in FIG. 3 , a connector 72 is attached to a front end portion of each wire harness 74 . The connector 72 is connected to the wiring 71 (see FIG. 8 ) on the small camera 70 side. Thereby, power and the like can be supplied to the compact camera 70 . In addition, the image data captured by the small camera 70 can be sent 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 arranged where each connector is arranged. In the example shown in FIG. 3 , four connector protection members 43 are arranged along the open end (on the side of the intermediate cover 21 ). However, the number of 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 wire 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 the assembled state of the refrigerator 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 Figure 8). That is, the polyurethane foam cannot enter the region where the connector 72 is arranged.

Connector protection member 43 is preferably formed of a heat insulating material in order to maintain the heat insulating performance of refrigerator compartment door 11 . In addition, in order to be able to form the space P easily, it is preferable to form it with a material softer than the foamed polyurethane which is the main component of the heat insulating layer 44 . In the present embodiment, the connector protection member 43 is formed of expanded polystyrene (second heat insulating material).

Expanded polystyrene is formed with polystyrene containing air cells. Expanded polystyrene is softer than expanded polyurethane and can be easily processed into desired shapes. Therefore, in the refrigerator 1 of the present embodiment, 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 . In addition, in FIG. 5 and FIG. 6, a part of the structure of the front side (the side facing the front member 41) of the door back 31 is shown. Specifically, FIGS. 5 and 6 show the detailed configuration of the open end side 31 a (middle cover 21 side) where the wire harness 74 is arranged.

As shown in FIG. 5, let the left end part of the door back 31 be 31a, and let the right end part of the door back 31 be 31b. The left end portion 31a corresponds to an open end portion where 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 respectively disposed at positions corresponding to the connector protection members 43 on the front member 41 side. Therefore, in the example shown in FIG. 5 , four second connector protection members 33 are arranged along the open end portion (middle cover 21 side) corresponding to the connector protection member 43 on the side of the front member 41 . However, the number of 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 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 described above. Moreover, the front-end|tip part of the wire harness 74 containing the connector 72 is accommodated in this space P. Furthermore, in the state where the small camera 70 is mounted, the wiring 71 on the side of the small camera 70 connected through the connector 72 is also arranged in the space P. As shown in FIG.

In this embodiment, as shown in FIG. 6 , the second connector protection members 33 are respectively arranged along the arrangement positions of the protruding walls 32 . The reason for this is that 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 where electronic components are mounted.

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 . In addition, in order to be able to form the space P easily, it is preferable to form it with a material softer than the foamed polyurethane which is the main component of the heat insulating layer 44 . 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 .

The front member 41 is disposed facing the door back 31 in a state where the heat insulating layer 44 is provided inside, and the refrigerator compartment door 11 shown in FIG. 7 is configured.

FIG. 8 shows the internal structure of the protruding wall 32 where the compact camera 70 is installed. The connector protection member 43 and the second connector protection member 33 are overlapped in the front-rear direction in a state where the front member 41 and the door back 31 are arranged and assembled to face the refrigerator compartment door 11 . In addition, the respective spaces P formed in the respective protective members 43 and 33 are connected to form one space P. As shown in FIG. In this space P, the wiring 71 electrically connected to the compact camera 70, the connector 72, and the wire harness 74 are arrange|positioned.

(about the manufacturing method of the refrigerator door)

Next, the manufacturing method of the refrigerator compartment door 11 which concerns on one aspect of this invention is demonstrated. As mentioned above, refrigerator compartment door 11 is provided with electronic components such as compact camera 70 . The manufacturing method of this kind of refrigerator compartment door 11 includes at least the process of arranging the front member 41 having the connector protection member 43 and the door back 31 having the electronic component installation part facing each other; The process of foaming the raw material of the foam heat insulating material to form a heat insulating layer; and the process of mounting electronic components on the electronic component installation part formed on the side of the door back 31 .

In the above manufacturing method, the space P for arranging the connector 72 and the wiring 71 connected to the electronic component is formed in the connector protection member 43 . In addition, in the process 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 overlaps the electronic component installation portion in the front-rear direction.

Hereinafter, a more specific manufacturing method will be described with reference to FIGS. 9 and 10 . Fig. 9(a) and Fig. 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 line frame shown in FIG. 6 . (a) of FIG. 10 and (b) of FIG. 10 have shown 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 line frame shown in FIG. 3 .

As shown in FIG. 9( a ), the door back 31 is provided with second connector protection members 33 a and 33 b. Moreover, the space P1 is formed in the 2nd connector protection member 33a, and the space P2 is formed in the 2nd connector protection member 33b.

As shown in FIG. 10( a ), the front member 41 is provided with connector protection members 43 a and 43 b. Moreover, the space P1 is formed in the connector protection member 43a, and the space P2 is formed in the connector protection member 43b. Moreover, the front-end|tip part of the wire harness 74 which has the connector 72 is accommodated in space P1 and space P2.

In addition, before the process of arranging the front member 41 and the door back 31 facing each other, as shown in (b) of FIG. P2. Similarly, as shown in FIG. 10( b ), the sheet member 82 is attached to the surfaces of the connector protection members 43 a and 43 b 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 polyurethane foam is added to any one 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.

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 is opposed to the space P1 of the second connector protection member 33a and the space P2 of the connector protection member 43b is opposed to the space P2 of the second connector protection member 33b. In such a manner, the front member 41 and the door back 31 are arranged.

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

In addition, the respective spaces P1 and P2 are covered with the sheet member 81 or 82 during the production reaction of foamed polyurethane. Therefore, even when the space P on the side of the connector protection member 43 and the space P on the side of the second connector protection member 33 are arranged with a slight offset or some gaps are formed, entry of the polyurethane foam into the space P can be more reliably prevented.

After that, a small camera 70 is installed at the front end 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. Then, the sheet members 81 and 82 are torn off by entering the space P through the formed notch. Thereby, the connector 72 housed in the space P on the side of the connector protection member 43 can be drawn out. In addition, the wiring 71 of the compact camera 70 is passed through a notch formed in the door back 31 . Next, the wiring 71 is connected to the connector 72, thereby completing the installation of the compact video camera 70 (see FIG. 8 ).

In addition, the notch can also be formed in advance on the door back 31 , and the place where the electronic components are installed on the door back 31 can also be used as the notch. In this case, the notch is surrounded by the connector protection member 33 so that the foamed polyurethane does not penetrate into the notch. Alternatively, a sealing member such as an adhesive tape is attached to the notch so that the foamed polyurethane does not leak out of the door back 31 from the notch, and then the foamed polyurethane is formed to form the heat insulating layer 44 .

(Summarize)

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 contacting the foamed urethane which is the main component of the heat insulating layer 44 . That is, it is possible to prevent the connector 72 from being corroded by the polyurethane foam expanded when the refrigerator compartment door 11 is manufactured, and being buried in the polyurethane foam.

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

Moreover, in the refrigerator compartment door 11 of this embodiment, the connector protection member 43 is formed with the 2nd heat insulating material (for example, foamed polystyrene) different from foamed polyurethane. Therefore, it is possible to suppress a reduction in the heat insulation performance of refrigerator door 11 .

In addition, in the refrigerator compartment door 11 of this embodiment, the 2nd connector protection member 33 is provided in the electronic component installation part of the door back 31. As shown in FIG. The second connector protection member 33 forms a space P in which the connector 72 is arranged together with the connector protection member 43 . Accordingly, a larger space for arranging the connector 72 can be 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, it is possible to reduce the possibility that polyurethane foam enters the space P for accommodating the connector 72 and the like.

(Second Embodiment)

Next, a second embodiment of the present invention will be described. In the second embodiment, the mounting structure of the electronic components is different from that in the first embodiment. Regarding other configurations, basically the same configurations as those of the first embodiment are applicable. Therefore, the following description will focus on the mounting structure of electronic components.

Fig. 11 shows a cross-sectional configuration of a refrigerator compartment door 111 of the refrigerator 1 according to the second embodiment. In addition, FIG. 12 and FIG. 13 have shown the left side of the refrigerator compartment door 111 (the side which released|released the end part side). The main constituent members of refrigerator compartment door 111 include front member 141 , door back 131 , and heat insulating layer 44 .

As in the first embodiment, the connector protection member 143 is provided with a space P for accommodating the front end portion of the wire harness 74 including the connector 72 . The space P is obtained by forming a recess on the surface of the connector protection member 143 . Similar to the first embodiment, the connector protection member 143 is formed of expanded polystyrene (second heat insulating material).

In addition, in the first embodiment, the second connector protection member 33 is provided at a position corresponding to the connector protection member 43 on the side of the door back 31 . On the other hand, in the second embodiment, the connector protection member is not provided on the door back 131 . Therefore, as shown in FIG. 11 , the connector protection member 143 is formed in contact with the door back 131 .

In addition, the front member 141 is arranged to face the door back 131 so that the concave portion 132 of the door back 31 is located at a position corresponding to the space P formed in the connector protection member 143 . In addition, an opening is provided in the recess 132 , and the opening faces the space P formed in the connector protection member 143 . On the surface of the connector protection member 143, a sheet member is pasted so as to cover the space P, as in the first embodiment. In addition, a sheet member may be attached to the opening of the recess 132 .

In this way, after the front member 141 and the door back 131 are arranged, the raw material of polyurethane foam is injected between the front member 141 and the door back 131 to form rigid polyurethane foam to form the heat insulating layer 44 .

On the other hand, the camera mounting structure 135 is formed separately from the refrigerator compartment door 111 . The camera mounting structure 135 is constituted by the small camera 70, the wiring 71, the second connector protection member 133, the mounting part 136, and the like. The same structure as that of the first embodiment can be applied to the compact camera 70 and the wiring 71 .

The mounting portion 136 forms the outer shape of the camera mounting structure 135 . The attachment portion 136 can be formed of the same resin material as that of the door back 131 , for example. The mounting portion 136 is arranged to protrude rearward from the surface of the door back 131 . The attachment portion 136 has a substantially cylindrical shape that is substantially the same shape as the protruding wall 32 in cross section, and has a cavity formed therein. In addition, a small camera 70 is attached to one end portion (tip portion) of the attachment portion 136 . Moreover, the other end part of the attachment part 136 is connected with the door back 131. As shown in FIG.

In addition, the second connector protection member 133 is disposed inside the mounting portion 136 . The second connector protection member 133 is arranged to occupy a part of the inner space of the mounting portion 136 having a substantially cylindrical shape. The second connector protection member 133 is formed of a heat insulating material such as expanded polystyrene, like the connector protection member 143 . In the present embodiment, the second connector protection member 133 is arranged at a position corresponding to the outside of the refrigerator 1 .

In the space P, wiring 71 connected to the compact camera 70 is arranged. As shown in FIG. 11 , in the state where the camera mounting structure 135 is mounted on the door back 131 , the space P inside the mounting portion 136 and the space P of the connector protection member 143 formed on the side of the refrigerator compartment door 111 are at least partly viewed from the front. overlapping. Thus, the space P of the connector protection member 143 and the space P of the second connector protection member 133 form a space for arranging the connector 72 , the wiring 71 , and the wire harness 74 of the compact camera 70 .

Camera attachment structure 135 is attached to refrigerator door 111 after refrigerator door 111 is formed. When the camera mounting structure 135 is attached to the recess 132 of the door back 131 , the connector 72 and the front end of the wire harness 74 housed in the space P in the connector protection member 143 are taken out from the opening formed in the recess 132 . At this time, when the sheet member is pasted to the connector protection member 143 or the opening, the sheet member is torn to lead out the front end of the connector 72 and the wire harness 74 . Thereafter, the wiring 71 is connected to the connector 72 , and the mounting portion 136 is fixed to the door back 131 .

As described above, according to the configuration of the second embodiment, by attaching the camera mounting structure 135 to the concave portion 132 of the door back 131, the small camera 70 can be installed on the back of the refrigerator compartment door 111. Thus, electronic components can be more easily mounted on the door back 131 of the refrigerator compartment door 111 . In addition, since the camera mounting structure 135 is formed independently of the refrigerator compartment door 111, it can be easily detached from the refrigerator compartment door 111 even when the compact camera 70 is replaced due to failure or upgrade.
