Detailed description of the specific embodiment

[0018] Hereinafter, an embodiment of the refrigerator will be described while referring to the attached Figure 1 while explaining one embodiment of the refrigerator. Figure 1 The exemplified refrigerator 10 has a plurality of storage chambers 12, 13, 14, 15, 16 formed inside a rectangular box-shaped heat insulating box body 11 that constitutes its outer contour. The heat insulating box body 11 is an example of the refrigerator main body. Various storage items such as foodstuffs can be stored inside the storage chambers 12, 13, 14, 15, 16. Although detailed illustration is omitted, the heat insulating box body 11 has a configuration with a heat insulating material between the inner box and the outer box. As the heat insulating material constituting the heat insulating box body 11, for example, various heat insulating materials such as a vacuum heat insulating panel, foamed polyurethane, and a heat insulating molded body obtained by molding a heat insulating material can be applied.

[0019] In this case, the storage chamber 12 is a refrigerating chamber maintained at a refrigerating temperature zone. Hereinafter, the storage chamber 12 may sometimes be referred to as the "refrigerating chamber 12". In this case, the storage chamber 13 is a vegetable chamber maintained at a refrigerating temperature zone. Hereinafter, the storage chamber 13 may sometimes be referred to as the "vegetable chamber 13". In this case, the storage chamber 14 is an ice-making chamber maintained at a freezing temperature zone. Hereinafter, the storage chamber 14 may sometimes be referred to as the "ice-making chamber 14". In this case, the storage chamber 15 is a small freezing chamber maintained at a freezing temperature zone. Hereinafter, the storage chamber 15 may sometimes be referred to as the "small freezing chamber 15". In this case, the storage chamber 16 is a large freezing chamber maintained at a freezing temperature zone. Hereinafter, the storage chamber 16 will be referred to as the "large freezing chamber 16".

[0020] The refrigerating chamber 12 becomes the uppermost storage chamber among the multiple storage chambers 12, 13, 14, 15, and 16 provided in the refrigerator 10. The vegetable chamber 13 is provided below the refrigerating chamber 12 and at a position approximately in the center in the vertical direction of the heat-insulating cabinet 11. The ice-making chamber 14 and the small freezing chamber 15 are provided below the vegetable chamber 13 and arranged horizontally along the lateral direction of the refrigerator 10 within the heat-insulating cabinet 11. The large freezing chamber 16 is provided below the ice-making chamber 14 and the small freezing chamber 15 within the heat-insulating cabinet 11. The large freezing chamber 16 becomes the lowermost storage chamber among the multiple storage chambers 12, 13, 14, 15, and 16 provided in the refrigerator 10.

[0021] The refrigerating chamber 12 has a rectangular opening at its front. The front opening of the refrigerating chamber 12 is opened and closed by a storage chamber door that can rotate in the left-right direction, that is, a rotatable refrigerating chamber door 12D. The vegetable chamber 13 has a rectangular opening at its front. The front opening of the vegetable chamber 13 is opened and closed by a storage chamber door that can move in the front-rear direction, that is, a pull-out vegetable chamber door 13D. The ice-making chamber 14 has a rectangular opening at its front. The front opening of the ice-making chamber 14 is opened and closed by a storage chamber door that can move in the front-rear direction, that is, a pull-out ice-making chamber door 14D. The small freezing chamber 15 has a rectangular opening at its front. The front opening of the small freezing chamber 15 is opened and closed by a storage chamber door that can move in the front-rear direction, that is, a pull-out small freezing chamber door 15D. The large freezing chamber 16 has an opening at its front. The front opening of the large freezing chamber 16 is opened and closed by a storage chamber door that can move in the front-rear direction, that is, a pull-out large freezing chamber door 16D. The refrigerating chamber door 12D, the vegetable chamber door 13D, the ice-making chamber door 14D, the small freezing chamber door 15D, and the large freezing chamber door 16D are all examples of storage chamber doors that can open and close the openings of the storage chambers.

[0022] The refrigerating compartment door 12D is pivotally supported by a rotating shaft at an end portion on one side in the left - right direction of the refrigerating compartment door 12D, which is the right - hand end portion when observing the refrigerating compartment door 12D in a closed state where the front opening of the refrigerating compartment 12 is blocked, from the front side of the refrigerator 10. That is, when the refrigerator 10 is observed from the front side, hinge portions 21 and 22 are provided at the right - hand end portion. The hinge portion 21 is provided at the upper part of the right - hand end of the heat - insulating cabinet 11 and has a rotating shaft 21a extending downward. The hinge portion 22 is provided at a position between the refrigerating compartment door 12D and the vegetable compartment door 13D at the right - hand end of the heat - insulating cabinet 11 and has a rotating shaft 22a extending upward.

[0023] As described above, the refrigerator 10 is configured such that the rotating shafts 21a and 22a are provided on the heat - insulating cabinet 11 rather than on the refrigerating compartment door 12D. In addition, the refrigerating compartment door 12D is pivotally supported by the rotating shafts 21a and 22a at one side in the left - right direction, that is, the right - hand end portion, and is configured to be rotatable in the left - right direction.

[0024] An operation portion 31 is provided on the refrigerating compartment door 12D. The operation portion 31 is disposed at a portion on the other side, that is, the left - hand side in the left - right direction of the refrigerating compartment door 12D. More specifically, the operation portion 31 is disposed at a position where, when observing the refrigerating compartment door 12D in a closed state where the front opening of the refrigerating compartment 12 is blocked, it is to the left of the center portion in the left - right direction and below the center portion in the up - down direction. In addition, the operation portion 31 is disposed at a position slightly closer to the inside than the left - hand side surface of the refrigerating compartment door 12D. The operation portion 31 includes a so - called capacitive electrostatic touch sensor 32. The electrostatic touch sensor 32 is an example of a detection portion and can detect the approach or contact of a human body, more specifically, the finger of a user, based on a change in electrostatic capacitance. That is, the electrostatic touch sensor 32 functions as a so - called touch switch.

[0025] In general refrigerators, it is mainstream that the operation portion for the user to operate is provided on the rotatable free - end side of the storage compartment door. Thus, in the refrigerator 10 of the present invention, the electrostatic touch sensor 32 is also disposed at a position biased toward the rotatable free - end of the refrigerating compartment door 12D, that is, on the side opposite to the right - hand end portion pivotally supported by the rotating shafts 21a and 22a, which is the left - hand end portion side. In addition, most general refrigerators have a configuration where the dimension in the up - down direction is longer than the dimension in the left - right direction, that is, the so - called vertically - long refrigerator is mainstream. Therefore, by making the electrostatic touch sensor 32 also have a configuration where the dimension in the up - down direction is longer than the dimension in the left - right direction, a configuration with a higher design harmony with the overall shape of the refrigerator 10 can be achieved.

[0026] As Figure 2As illustrated, the refrigerator 10 includes a rectangular plate-shaped substrate 33. The capacitive touch sensor 32 is provided on the substrate 33. The capacitive touch sensor 32 detects the approach and contact of a human body, and preferably ensures its area as large as possible. Thus, the area occupied by the capacitive touch sensor 32 in the substrate 33 is preferably as large as possible.

[0027] In addition, the refrigerator 10 includes a wiring 34 connected to the substrate 33 inside the refrigerating chamber door 12D. The wiring 34 extends from inside the heat-insulating cabinet 11 and is then introduced into the refrigerating chamber door 12D. The wiring 34 is arranged inside the refrigerating chamber door 12D to be substantially along the diagonal of the refrigerating chamber door 12D, but is arranged in a configuration with inventive efforts implemented everywhere. Next, the configuration of the wiring 34 will be described in detail.

[0028] That is, the refrigerator 10 includes a hinge hole 35 through which the wiring 34 can be introduced into the refrigerating chamber door 12D. The hinge hole 35 is provided in the right side portion of the upper part of the outer frame forming the outer contour of the refrigerating chamber door 12D, and rotatably houses the rotating shaft 21a of the hinge portion 21. The wiring 34 is introduced into the refrigerating chamber door 12D through the hinge hole 35. The hinge hole 35 is an example of an introduction hole. The opening diameter of the hinge hole 35 is at least large enough to house the rotating shaft 21a and the wiring 34.

[0029] In addition, the refrigerator 10 includes a hinge hole 36. The hinge hole 36 is provided in the right side portion of the lower part of the outer frame forming the outer contour of the refrigerating chamber door 12D, and rotatably houses the rotating shaft 22a of the hinge portion 22. The opening diameter of the hinge hole 36 is at least large enough to house the rotating shaft 22a.

[0030] The capacitive touch sensor 32 is arranged on the other side of the refrigerating chamber door 12D opposite to the side where the hinge hole 35 is provided, which is the left side portion when observing the refrigerating chamber door 12D in the blocked state of blocking the front opening of the refrigerating chamber 12 from the front side of the refrigerator 10. The substrate 33 has a connector 37 between the capacitive touch sensor 32 and the other side, i.e., the left side surface of the refrigerating chamber door 12D. The connector 37 is an example of a connecting portion for connecting the wiring 34. The wiring 34 is introduced into the refrigerating chamber door 12D from the hinge hole 35 and then extends downward. Then, the wiring 34 is connected to the connector 37 while avoiding the capacitive touch sensor 32 inside the refrigerating chamber door 12D.

[0031] To describe in more detail, the wiring 34 has an introduction portion 34a that extends into the refrigerator door 12D after being introduced from the hinge hole 35, and a portion 34b where the extending direction changes from the introduction portion 34a toward the other side of the refrigerator door 12D, i.e., the left side. The introduction portion 34a is an example of the first portion, and the portion 34b where the extending direction changes is an example of the second portion. After the wiring 34 extends linearly downward in the introduction portion 34a, it bends toward the other side of the refrigerator door 12D, i.e., the left side, in the portion 34b where the extending direction changes. Therefore, the portion 34b where the extending direction changes can also be defined as the "bending portion" of the wiring 34.

[0032] In addition, the introduction portion 34a does not necessarily have to have an extended long strip portion, and it can also be a portion that includes the portion introduced from the hinge hole 35 or the portion directly below the introduced portion. In addition, the portion 34b where the extending direction changes does not necessarily have to have an extended long strip portion, and it can also be a portion that includes the portion bent from the introduction portion 34a or the portion just after bending. In addition, within the refrigerator door 12D, various parts of the wiring 34 are fixed by tape or the like (not shown).

[0033] The electrostatic touch sensor 32 is disposed between the portion 34b where the extending direction of the wiring 34 changes and the connector 37 of the substrate 33. The wiring 34 is configured to be separated downward from the virtual straight line L that connects the portion 34b where the extending direction changes and the connector 37. The virtual straight line L can be defined as a straight line representing the shortest distance between the portion 34b where the extending direction changes and the connector 37. In this case, the distance between the wiring 34 and the virtual straight line L is configured such that the closer it is to the electrostatic touch sensor 32, the greater the distance becomes.

[0034] In addition, the wiring 34 has a bypass portion 34c that bypasses the electrostatic touch sensor 32. In this case, the bypass portion 34c is disposed at a position lower than the electrostatic touch sensor 32. In addition, the bypass portion 34c is configured to have a predetermined distance from the lower end of the electrostatic touch sensor 32. This predetermined distance is preferably at least several millimeters to several centimeters.

[0035] In addition, by disposing the bypass portion 34c at a position lower than the electrostatic touch sensor 32 rather than higher, the wiring 34 can suppress excessive bending of the portion 34b where the extending direction changes. In this case, the bending angle K of the portion 34b where the extending direction changes is, for example, suppressed to 45 degrees or less. In addition, the bending angle K of the portion 34b where the extending direction changes is more preferably suppressed to, for example, 40 degrees or less.

[0036] The refrigerator compartment door 12D has a heat insulation material storage area R1 for storing the vacuum heat insulation panel 38, a substrate storage area R2 for storing the substrate 33, and a partition wall 39 that separates the heat insulation material storage area R1 and the substrate storage area R2. The vacuum heat insulation panel 38 is an example of a heat insulation material. The portion other than the vacuum heat insulation panel 38 in the heat insulation material storage area R1 is filled with a heat insulation material such as foamed polyurethane (not shown).

[0037] The substrate storage area R2 is provided in a portion of the left end face of the refrigerator compartment door 12D that is below the central portion in the vertical direction and is recessed toward the right side of the refrigerator compartment door 12D. A cover member 40 is provided at the left end of the substrate 33. As the substrate 33 is stored in the substrate storage area R2, the opening of the substrate storage area R2 is blocked by the cover member 40.

[0038] An insertion hole 39a through which the wiring 34 can be inserted is formed in the partition wall 39. The connector 37 is disposed on the lower side of the substrate 33, that is, at a position below the central portion in the vertical direction. The insertion hole 39a is disposed in a portion of the partition wall 39 that separates the lower side of the substrate storage area R2. The wiring 34 led out from the insertion hole 39a into the substrate storage area R2 is connected to the connector 37 in the upward direction.

[0039] As Figure 3 illustrated, in the manufacturing process of the refrigerator 10, the wiring 34 is connected to the connector 37 of the substrate 33 outside the substrate storage area R2. Then, the substrate 33 is stored in the substrate storage area R2 with the wiring 34 connected to the connector 37. At this time, the wiring 34 led out to the substrate storage area R2 side from the insertion hole 39a is pressed into the substrate storage area R2 and is bent.

[0040] However, the wiring 34 between the insertion hole 39a and the connector 37 is led out from the lower side of the substrate storage area R2. Therefore, the wiring 34 between the insertion hole 39a and the connector 37 is bent downward under the action of gravity. Therefore, as Figure 2 illustrated, the wiring 34 between the insertion hole 39a and the connector 37 converges in a region below the electrostatic touch sensor 32, and it is possible to prevent the wiring 34 from overlapping with the electrostatic touch sensor 32 or the wiring 34 from being too close to the electrostatic touch sensor 32.

[0041] In addition, in Figure 2 and Figure 3 example, the insertion hole 39a is formed in a portion of the partition wall 39 that separates the lower side of the substrate storage area R2. However, the insertion hole 39a can be appropriately disposed at different positions. For example, it can also be formed in the lower side of a portion of the partition wall 39 that separates the side portion of the substrate storage area R2.

[0042] In the refrigerator 10 according to the present invention, the electrostatic touch sensor 32 is disposed on the other side of the refrigerating chamber door 12D opposite to the side where the hinge hole 35 is provided. The substrate 33 has a connector 37 for connecting the wiring 34 between the electrostatic touch sensor 32 and the side surface of the other side of the refrigerating chamber door 12D. The wiring 34 extends from the hinge hole 35 within the refrigerating chamber door 12D and is connected to the connector 37 while avoiding the electrostatic touch sensor 32. According to this configuration example, within the refrigerating chamber door 12D, it is possible to avoid the wiring 34 from being disposed close to or in contact with the electrostatic touch sensor 32, and it is possible to suppress malfunction of the electrostatic touch sensor 32 caused by noise generated from the wiring 34 disposed within the refrigerating chamber door 12D.

[0043] In addition, for example Figure 4 As exemplified as Comparative Example 1, by disposing the connector 37 at a position closer to the hinge hole 35 than the electrostatic touch sensor 32, even if the wiring 34 is not disposed in a manner that avoids the electrostatic touch sensor 32, it is possible to avoid the wiring 34 from being disposed close to or in contact with the electrostatic touch sensor 32. However, in the configuration where the connector 37 is disposed at a position closer to the hinge hole 35 than the electrostatic touch sensor 32, it is necessary to further expand the substrate 33 within the refrigerating chamber door 12D, and accordingly, the volume of the heat insulating material storage region R1 will decrease. That is, the volume of the region R1 where the heat insulating material can be disposed decreases, and the heat insulating performance of the refrigerating chamber door 12D deteriorates.

[0044] Therefore, as in the refrigerator 10 of the present invention, it is preferable that the connector 37 is disposed on the side opposite to the hinge hole 35 side with respect to the electrostatic touch sensor 32. However, if the wiring 34 introduced from the hinge hole 35 is disposed at the shortest distance from the connector 37, that is, for example, along the virtual straight line L, the wiring 34 will be disposed close to or in contact with the electrostatic touch sensor 32. Therefore, the refrigerator 10 of the present invention is a configuration example in which an inventive effort of disposing the wiring 34 in a manner that avoids the electrostatic touch sensor 32 is implemented.

[0045] In addition, according to the refrigerator 10, the wiring 34 has an introduction portion 34a extending from the hinge hole 35 into the refrigerating chamber door 12D, and an extension direction changing portion 34b whose extension direction changes from the introduction portion 34a to the other side of the refrigerating chamber door 12D. And, the electrostatic touch sensor 32 is disposed between the extension direction changing portion 34b and the connector 37. And, the wiring 34 is disposed away from the virtual straight line L connecting the extension direction changing portion 34b and the connector 37. In addition, the wiring 34 has a bypass portion 34c that bypasses the electrostatic touch sensor 32.

[0046] According to this configuration example, the wiring 34 extends from the side of the electrostatic touch sensor 32 opposite to the connector 37 and is connected to the connector 37. However, since the wiring 34 is formed with a bypass portion 34c that bypasses the electrostatic touch sensor 32, it is possible to more reliably avoid arranging the wiring 34 close to or in contact with the electrostatic touch sensor 32, and it is possible to more reliably suppress malfunction of the electrostatic touch sensor 32 caused by noise generated from the wiring 34.

[0047] In addition, according to the refrigerator 10, the refrigerating chamber door 12D is configured to be rotatable by being pivotally supported by a rotating shaft 21a and 22a on the right side, which is one side of the refrigerating chamber door 12D. The rotating shafts 21a and 22a are provided on the heat-insulating cabinet 11, and the hinge holes 35 and 36 are configured to receive the rotating shafts 21a and 22a in the refrigerating chamber door 12D. The bypass portion 34c of the wiring 34 is arranged at a position lower than the electrostatic touch sensor 32.

[0048] According to this configuration example, it is possible to suppress the bending angle K in the extension direction changing portion 34b of the wiring 34, avoid excessive bending of the wiring 34, and reduce the load applied to the wiring 34.

[0049] In addition, according to the refrigerator 10, the refrigerating chamber door 12D includes a heat-insulating material storage area R1 for storing the vacuum heat-insulating panel 38, a substrate storage area R2 for storing the substrate 33, and a partition wall 39 that separates the heat-insulating material storage area R1 and the substrate storage area R2. The partition wall 39 is an example of a separating portion. An insertion through hole 39a through which the wiring 34 can be inserted is provided in the partition wall 39. The connector 37 is arranged on the lower side of the substrate 33. The insertion through hole 39a is arranged in a portion of the partition wall 39 that separates the lower side of the substrate storage area R2.

[0050] According to this configuration example, in the manufacturing process of the refrigerator 10, when the substrate 33 is stored in the substrate storage area R2, it is possible to easily store the wiring 34 in an area lower than the electrostatic touch sensor 32 by utilizing the action of gravity. As a result, it is possible to suppress the wiring 34 from overlapping or being too close to the electrostatic touch sensor 32 in the substrate storage area R2, and it is possible to more reliably suppress malfunction of the electrostatic touch sensor 32 caused by noise generated from the wiring 34.

[0051] In addition, according to the refrigerator 10, the wiring 34 is connected to the connector 37 in the upward direction. Here, as exemplified as Comparative Example 2 in Figure 5 when studying the configuration in which the wiring 34 is connected to the connector 37 in the downward direction, it can be seen that the wiring 34 may hang down from above the connector 37 to a position lower than the connector 37. And if the wiring 34 hangs down in this way, the wiring 34 may be subjected to useless stress and load due to gravity. In addition, as inFigure 5 As exemplified in Comparative Example 3, it is conceivable that when the wiring 34 is connected to the connector 37 horizontally, the wiring 34 may hang down below the connector 37 in the lateral direction of the connector 37. And if the wiring 34 hangs down like this, the wiring 34 may be subjected to unnecessary stress and load due to gravity.

[0052] In contrast, according to the configuration in which the wiring 34 is connected to the connector 37 upward as in the refrigerator 10 of the present invention, even if gravity acts on the wiring 34, the action is applied along the direction in which the wiring 34 extends. Therefore, it is possible to suppress the wiring 34 from being subjected to unnecessary stress and load. Then, by suppressing the wiring 34 from being subjected to unnecessary stress and load, it is possible to suppress the wiring 34 from detaching from the connector 37.

[0053] In addition, the present invention is not limited to the above-described one embodiment, and can be appropriately changed, extended, etc. within the scope not departing from its gist. For example, the wiring 34 includes various wirings such as a signal line for transmitting an operation instruction signal to a control device (not shown) that controls the overall operation of the refrigerator 10, and a power supply line for supplying power from the refrigerator main body side to the storage room door side.

[0054] The arrangement mode of the wiring 34 in the refrigerating chamber door 12D is not limited to the above arrangement mode, and various arrangement modes can be applied as long as it at least avoids the arrangement of the electrostatic touch sensor 32. In addition, as long as the wiring 34 at least bypasses the electrostatic touch sensor 32, it may be in contact with or close to components other than the electrostatic touch sensor 32.

[0055] For example Figure 6 As exemplified, the refrigerator 10 may be configured to include a metal noise shielding member 41 between the electrostatic touch sensor 32 and the wiring 34. The noise shielding member 41 is an example of a suppression portion. The noise shielding member 41 is, for example, a foil-like member formed of a metal material such as aluminum, and suppresses the propagation of noise such as electromagnetic waves generated from the wiring 34 to the electrostatic touch sensor 32.

[0056] In addition, in Figure 6In the illustrated configuration example, the noise shielding member 41 covers the entire substrate 33 including the capacitive touch sensor 32. Thus, by covering the entire substrate 33 including the capacitive touch sensor 32 with the noise shielding member 41, it is also possible to suppress the propagation of noise generated from components other than the wiring 34 to the capacitive touch sensor 32. However, the noise shielding member 41 may also be sized to cover only a part of the substrate 33, particularly the part where the capacitive touch sensor 32 is disposed. Additionally, the noise shielding member 41 may also be sized to cover at least only the part between the capacitive touch sensor 32 and the wiring 34. Further, the refrigerator 10 may also be configured such that, instead of the noise shielding member 41, or while having the noise shielding member 41, the wiring 34 itself is covered by the noise shielding member. That is, for example, the refrigerator 10 may also be configured to wind a foil-like member formed of a metal material such as aluminum around the wiring 34.

[0057] Further, as Figure 7 illustrated, the refrigerator 10 may also be configured such that the rotating shaft 51 is provided on the refrigerating chamber door 12D and not on the heat insulating cabinet 11, and the rotating shaft 51 is rotatably supported by an unillustrated hinge hole provided on the heat insulating cabinet 11 side. Then, in this case, it is preferably configured such that the introduction hole 52 for introducing the wiring 34 into the refrigerating chamber door 12D is provided in the rotating shaft 51. In this case, the introduction hole 52 is formed on the circumferential side surface of the rotating shaft 51.

[0058] The storage chamber is not limited to the refrigerating chamber 12 and may also be other storage chambers. Additionally, the storage chamber door is not limited to the refrigerating chamber door 12D and may also be other storage chamber doors. Further, the refrigerating chamber door 12D may also be configured to be rotatably supported by a rotating shaft at the other end in the left-right direction of the refrigerating chamber door 12D, which is the left end when observing the refrigerating chamber door 12D in a closed state closing the front opening of the refrigerating chamber 12 from the front side of the refrigerator 10 in this case. Also, the refrigerator 10 is not limited to the configuration in which the front opening of the refrigerating chamber 12 is closed by one refrigerating chamber door 12D, and for example, it may also be a configuration in which the front opening of the refrigerating chamber is closed by a left refrigerating chamber door and a right refrigerating chamber door, that is, a so-called French door type configuration.
