Description

  The present invention relates to a lead wire routing configuration using a refrigerator, particularly a door shaft support portion of the refrigerator.

  In general, a refrigerator is pivotally supported by a refrigerator main body via a hinge so that the door can be opened and closed. A lead wire that connects an operation display unit provided on the door and a control unit provided on the refrigerator main body using the hinge portion is generally used. The wiring is routed (see, for example, Patent Document 1).

  FIG. 22 shows a lead wire routing configuration in the door shaft support portion described in Patent Document 1, wherein the hinge shaft 104 of the hinge 103 that pivotally supports the refrigerator main body 101 and the door 102 is hollow, and the lead wire 105 Is routed through the hollow portion of the hinge shaft 104. The control unit on the refrigerator main body 101 side and the operation display unit on the door 102 side are connected.

JP 2004-293913 A

  According to the lead wire routing configuration described in Patent Document 1, the lead wire 105 is not twisted by opening and closing the door 102, and the length of the lead wire 105 changes when the door 102 is opened and closed. Therefore, disconnection or damage of the lead wire 105 can be prevented.

  However, the hinge 103 used in the door shaft support structure has a hinge piece 103 a attached to the top surface of the refrigerator main body 101 and protruding upward from the top surface of the refrigerator main body 101. When the door 102 is opened, the side surface of the door 102 protrudes from the side surface of the refrigerator body 1. For these reasons, for example, it cannot be used in a refrigerator such as a wine cellar that is incorporated in the lower part of a system kitchen or the like.

  Accordingly, in the case of such a refrigerator, a hinge provided with a link mechanism is attached between the front end surface of the refrigerator main body and the inner surface of the door to pivotally support the door.

  However, in the case of the pivot support structure using the hinge with the link mechanism, the opening / closing locus of the rear end of the door when the door is opened / closed is the door rear end of the door pivoted using the hollow hinge shaft type hinge described above. Therefore, the change in the length of the lead wire when the door is opened and closed becomes large, and the load on the lead wire when the lead wire is bent is large. In addition, there are cases where the lead wire is bitten between the door end and the hinge component and damaged.

  The present invention has been made in view of these points, and an object of the present invention is to provide a highly reliable refrigerator that suppresses disconnection of lead wires and the like.

  In order to achieve the above object, the present invention comprises a refrigerator body, a door for opening and closing a storage chamber of the refrigerator body, and a hinge for pivotally supporting the door on the refrigerator body, wherein the hinge is a hinge having a crank mechanism. Attach one end to the refrigerator body and the other end to the door, and cover the outer part of the hinge on the refrigerator body side with a hinge cover, provide a through hole in the hinge cover, and route the lead hole through the lead wire As a configuration.

  Thereby, the change in the length of the lead wire caused by the opening and closing of the door can be reduced, and the lead wire can be prevented from being bent or twisted at the hinge portion to damage the lead wire.

  According to the present invention, even if the door is pivotally supported using a hinge having a link mechanism, the lead wire can be prevented from being damaged, and a highly reliable refrigerator can be obtained.

The perspective view which shows the state which attached the hinge support bracket to the box, (c) is the perspective view which shows the state which incorporated the inner box in the outer box, FIG. 17 is the half-cut perspective view which shows the hinge attachment part of the door of the refrigerator, 18 is an enlarged perspective view of a hinge attachment portion of the refrigerator door, FIG. 19 is a perspective view of the shaft support portion of the refrigerator lower portion viewed from the bottom side, and FIG. 20 is a view of the lower portion of the refrigerator door. FIG. 21 is a perspective view showing a lower end surface portion of the door of the refrigerator, with the shaft support portion with the hinge cover removed.

  The door 20 is pivotally supported on the refrigerator body 1 by hinges at the top and bottom. As shown in FIG. 15, the upper part of the door 20 is pivotally supported by the upper part of the refrigerator main body 1 through an upper hinge 75a so as to be opened and closed. Moreover, the lower part of the door 20 is pivotally supported by the lower part of the refrigerator main body 1 through the lower hinge 75b so that opening and closing is possible, as shown in FIG. The upper hinge 75a and the lower hinge 75b are each composed of a hinge having a link mechanism. That is, the upper hinge 75a and the lower hinge 75b are hinges having at least two link portions and three rotation axes, respectively.

As shown in FIGS. 17 and 18, the upper hinge 75 a is attached to a hinge mounting bracket 76 fixed to the inner surface of the upper end of the inner box 7. The hinge mounting bracket 76 is a metal plate whose cross section is bent in a substantially step shape so as to have the first and second mounting portions 76a and 76b. The first attachment portion 76a is a horizontal surface provided at the upper portion, and the second attachment portion 76b is provided below the first attachment portion 76a, and is a vertical position located on the front side from the front end of the first attachment portion 76a. It is a plane of direction.

  As shown in FIG. 16, the first mounting portion 76 a is fixed to the ceiling surface of the outer box 6 with screws 77. The second mounting portion 76b abuts against the inner surface of the hinge bracket mounting flange surface 7b of the inner box 7. The hinge metal fitting flange surface 7 b is a part of the upper flange portion of the inner box 7. As shown in FIGS. 17 and 18, the hinge mounting bracket 76 is fixed to the second mounting portion 76b with screws 77 via the hinge mounting flange surface 7b.

  As a result, the outer box 6 and the inner box 7 are integrally connected by the hinge mounting bracket 76.

  The lower hinge 75b that pivotally supports the lower portion of the door 20 has a lower surface of the lower hinge 75b covered with a hinge cover 78 as shown in FIGS. The hinge cover 78 includes a cover portion that covers the lower surface of the lower hinge 75b, and a lead wire regulating surface that is a surface substantially perpendicular to the cover portion and substantially parallel to the lower flange surface of the inner box 7. I have. The lead wire regulating surface is provided with a through hole 80 for regulating the movement range of the lead wire 79 described later.

  As shown in FIG. 20, the lower hinge 75 b includes a main body side fixing portion 751 fixed to the refrigerator main body 1 and a door side fixing portion 752 fixed to the door 20 side. A first link portion 754 is connected to the main body side fixing portion 751 via a main body side rotation shaft 753. A second link portion 756 is connected to the door side fixing portion 752 via a door side rotation shaft 755. The first link part 754 and the second link part 756 are connected via a moving rotation shaft 757. When the door 20 is closed, the first link portion 754 and the second link portion 756 overlap each other. In a state where the door 20 is opened, the door 20 protrudes from the refrigerator body 1 according to the lengths of the first link portion 754 and the second link portion 756. The upper hinge 75a has the same structure as the lower hinge 75b.

  By using such a hinge, when the door 20 is closed, as shown in FIG. 21, the side surface of the door 20 is substantially coincident with the side surface of the refrigerator main body 1 and the door 20 is opened. As shown in FIG. 19, the side surface of the door 20 can be positioned on the front side of the refrigerator body 1 (inside the side surface of the refrigerator body 1). For this reason, even if it is an undercounter type refrigerator built in a system kitchen etc., the door 20 can be opened and closed without interfering with the apparatus installed adjacent to the refrigerator, for example, a dishwasher.

  The lead wire 79 is an electric wire that electrically connects the operation display unit 23 provided on the upper portion of the door 20 and a control unit (not shown) provided on the back surface of the refrigerator body 1. The lead wire 79 from the operation display section 23 is wired along the bottom surface of the door 20 to the lower hinge 75b as shown in FIG. The lead wire 79 is drawn into the bottom surface of the refrigerator main body 1 through the through hole 80 of the hinge cover, and is connected to a control unit (not shown).

  The through hole 80 is a first restricting portion that restricts the movement of the lead wire 79 in the left-right direction at the portion where the lead wire 79 is drawn into the refrigerator body 1. The end of the through hole 80 on the center side of the refrigerator main body 1 is located on the side opposite to the central portion of the refrigerator main body 1 from the moving rotation shaft 757 in the state where the door 20 is closed. Further, the end of the through hole 80 on the center side of the refrigerator main body 1 is the anti-center of the refrigerator main body 1 from the midpoint of the line connecting the movable rotating shaft 757 and the main body side fixing portion 751 when the door 20 is closed. It is desirable to be located on the part side.

  The end of the through hole 80 on the side opposite to the central portion of the refrigerator main body 1 is located closer to the central side of the refrigerator main body 1 than the main body side rotation shaft 753.

  Furthermore, the center of the through hole 80 in the left-right direction (the width direction of the refrigerator main body 1) is located on an extension line X of an imaginary line passing through the center in the thickness direction of the door 20 with the door 20 fully opened. Is desirable (see FIG. 19). In the present embodiment, the first restricting portion is provided as the through hole 80 in the hinge cover 78, but may be provided directly in the refrigerator main body 1.

  The lead wire 79 drawn from the through hole 80 is held by a clip 81 provided on the bottom surface of the refrigerator body 1. The clip 81 is a second restricting portion that does not restrict the movement of the lead wire 79 in the axial direction (Y direction in FIG. 19) and restricts the movement of the lead wire 79 in the other direction. The position of the clip 81 in the width direction of the refrigerator main body 1 is the center side of the refrigerator main body 1 with respect to the moving rotation shaft 757 in the state where the door 20 is closed. The position of the clip 81 in the depth direction of the refrigerator body 1 is on the back side of the refrigerator body 1 from the lower hinge 75b.

  In the above configuration, the function and effect will be described below.

  The refrigerator door 20 is pivotally supported on the refrigerator main body 1 by upper and lower hinges 75, 75a. The lower hinge 75b is used as a lead wire, in this example, an operation display section provided on the upper portion of the door 20. A lead wire 79 is connected around 23 to a control unit (not shown) provided in the refrigerator main body 1.

  Here, the lead wire 79 from the operation unit 71 to the main body controller is bent by opening and closing the door 20. Further, the length of the lead wire required when the door 20 is closed is shorter than the length of the lead wire required when the door 20 is open. In particular, when a hinge having a link mechanism is used, the necessary difference in the length of the lead wire between the closed state and the open state of the door 20 becomes large. For these reasons, a load is applied to the lead wire 79 and the lead wire 79 may be disconnected.

  However, in this Embodiment, it draws in through the through-hole 80 provided in the hinge cover 78 of the lower hinge 75b to the bottom face of the refrigerator main body 1, and the drawing position is controlled. For this reason, the difference between the length of the lead wire required when the door 20 is closed and the length of the lead wire required when the door 20 is open can be reduced. Further, even if the lead wire 79 extends and contracts due to opening and closing of the door 20 and the length of the lead wire 79 changes, the lead wire 79 of the portion that is contracted and left is connected to the end portion of the door 20 and the lower hinge 75b. Can be prevented from being bitten between the two.

  That is, even if the door 20 is closed and the lead wire 79 is left in an excess state, the lead wire 79 of the portion having the excess dimension is restricted from moving to the center side of the refrigerator body 1 by the through hole 80. It moves to the bottom surface side of the refrigerator main body 1 through 80 and the clip 81. Therefore, even when the door 20 is pivotally supported using a hinge having a link mechanism and the lead wire 79 extends and contracts greatly, the load due to the bending of the lead wire 79 and the biting of the lead wire 79 are suppressed. Disconnection and the like can be prevented.

  In particular, the through-hole 80 restricts the movement of the lead wire 79 from the moving rotary shaft 757 to the side opposite to the center of the refrigerator main body 1, so that the amount of bending and deflection of the lead wire 79 is reduced and the lead wire 79 is damaged. Can be prevented more reliably.

Further, the clip 81 restricts the movement of the lead wire 79 in the depth direction of the refrigerator body 1 from the lower hinge 75 b to the back side of the refrigerator body 1 and allows the movement of the lead wire 79 in the axial direction. Thereby, it is possible to prevent an excess portion of the lead wire 79 generated by opening and closing the door 20 from being bitten by the lower hinge 75b.

  Particularly in this embodiment, the through hole 80 is provided on an extension line X of an imaginary line passing through the center in the thickness direction of the door 20 in a state where the door 20 is fully opened. As a result, the excessive dimension portion of the lead wire 79 generated when the door 20 is closed comes to slide straight through the through hole 80 and moves to the refrigerator main body side, thereby suppressing the bending at the hinge portion and the lead wire. 79 can be more reliably prevented.

  If the door 20 is attached to the inner plate 56 via a hinge, there is a problem that it is difficult to make the top surface of the outer box 6 parallel to the upper surface of the door 20, that is, it is difficult to ensure parallelism. However, in the present embodiment, the door 20 is attached to the hinge mounting bracket 76 connected to the outer box 6 via the inner box 7.

  Thereby, even if the door 20 is pivotally supported on the inner box 7, the parallelism of the door 20 with respect to the outer box 6 can be secured, and the problem that the door 20 tilts with respect to the outer box 6 can be solved. . Therefore, even if it is a refrigerator like the built-in type where the inclination of the door 20 is conspicuous, the inclination of the door 20 can be reliably prevented. As a result, the quality of the refrigerator is improved, and the yield can be increased, thereby reducing the cost.

  The operation display unit 23 provided on the upper portion of the door 20 is installed by elastically contacting the first and second pressing pieces 74a and 74b of the operation unit unit 71 with the inner wall portion of the operation unit installation recess 70. Therefore, the electrode film of the operation display unit 23 is pressed against the inner surface of the transparent front plate 68. Therefore, the detection accuracy of the electrostatic capacity at the time of the touch operation can be increased, and the operation quality can be improved.

  Further, since the operation unit installation recess 70 for installing the operation unit unit 71 has an inclined surface 73a on the back side of the operation unit unit 71, the gasket 62 is mounted using a dead space generated behind the inclined surface 73a. can do. That is, the operation unit 71 and the gasket 62 can be installed in an overlapping manner. Thereby, the installation space of the operation part unit 71 and the gasket 62 can be reduced, and the central plate 21 can be enlarged correspondingly to increase the visibility.

  Further, since the gasket 62 provided on the inner plate 56 of the door 20 is provided so as to be positioned between the opening of the storage chambers 3 and 4 and the operation unit unit 71, the cool air in the storage chambers 3 and 4 is provided. Can be prevented from flowing to the installation back surface portion of the operation unit 71 and cooling it. Thereby, troubles such as the occurrence of condensation due to excessive cooling of the operation unit 71 can be prevented.

  Further, the door 20 of the refrigerator is configured by sandwiching and holding the translucent central plate 21 between the outer plate 57 and the inner plate 56 of the frame-like edge frame 55, and thus holds and fixes the central plate 21. Therefore, the main components are only the outer plate 57 and the inner plate 56 of the edge frame 55, and the number of components can be greatly reduced. In addition, since the outer plate 57 and the inner plate 56 can be manufactured by relatively inexpensive injection molding, the component manufacturing cost can also be suppressed.

  In addition, it is difficult to form the inner plate 56 by injection molding and simultaneously form the concave portion 60 protruding toward the outer plate 57 and the rib protruding from the side surface forming the depression of the concave portion 60 on the inner plate 56. . However, in the present embodiment, the gasket holding configuration of the inner plate 56 that is difficult to form by the injection molding is configured by mounting the gasket holding member 61 on the recess 60 formed at the same time as the inner plate molding by the injection molding. .

  Therefore, although the number of parts is increased by one, the gasket holding member 61 is a linear member having the same cross-sectional shape and can be formed by inexpensive extrusion molding. For this reason, the cost increase due to an increase in the number of parts can be suppressed to a minimum. Therefore, the cost can be significantly reduced by reducing the number of parts and assembly man-hours and the cost of manufacturing parts.

  The convex portion 66 is configured to protrude from the opening portion of the concave portion 60, but is not a rib provided over the entire width of the concave portion 60, but is a projection provided at a predetermined interval, and thus is easily formed by injection molding. can do.

  Further, since the gasket holding member 61 has the gasket removal preventing rib 64 at the opening portion of the gasket holding recess 63, the gasket 62 can be firmly fixed and held without dropping off. Therefore, reliable sealing performance can be maintained. Moreover, although the rib 64 for gasket removal prevention protrudes in the opening part of the gasket holding | maintenance recessed part 63, since it is provided in the gasket holding member, it can form easily by extrusion molding.
