Description

refrigerator

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

Generally, a refrigerator is pivotally supported by a refrigerator body through a hinge so that the door can be opened and closed. Using this hinge portion, for example, a lead wire that connects an operation display unit provided on the door and a control unit provided on the refrigerator main body is routed and wired (see, for example, Patent Document 1). .

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

According to the lead wire routing configuration described in Patent Document 1, the lead wire 105 is not twisted by opening and closing of the door 102, and the length of the lead wire 105 when the door 102 is opened and closed. The lead wire 105 can be prevented from being broken or damaged.

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

Therefore, such a conventional refrigerator is configured such that 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 so that the door is pivotally supported.

However, in the case of a pivot support configuration using a hinge with a link mechanism, the opening / closing locus of the rear end of the door when the door is opened / closed is the door of the door pivotally supported using the hollow hinge shaft type hinge described above. It becomes larger than the movement locus of the rear end. For this reason, 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 is a case where the lead wire is caught between the door end portion and the hinge component and damaged.

JP 2004-293913 A

The present disclosure has been made in view of such problems, and provides a highly reliable refrigerator that suppresses disconnection of lead wires and the like.

Specifically, a refrigerator according to an example of the present disclosure includes a refrigerator main body, a storage chamber provided in the refrigerator main body, a door that opens and closes the storage chamber, and a hinge that pivotally supports the door on the refrigerator main body. Moreover, the refrigerator by an example of this indication is provided with the operation part provided in the door, the control part provided in the refrigerator main body, and the lead wire which electrically connects an operation part and a control part. The hinge has a link mechanism. At least one of the refrigerator main body and the door has a restricting portion that restricts the movement of the lead wire in the width direction of the refrigerator main body at a portion where the lead wire is drawn into the refrigerator main body from the door.

Such a configuration makes it possible to reduce the change in the length of the lead wire caused by opening and closing the door, and to prevent the lead wire from being bent or twisted at the hinge portion and damaging the lead wire. Therefore, with such a configuration, even if a hinge having a link mechanism is used and the door is pivotally supported, the lead wire can be prevented from being damaged, and a highly reliable refrigerator can be provided.

In the refrigerator according to an example of the present disclosure, the hinge includes at least a first link part pivotally supported by the refrigerator body, a second link part pivotally supported by the door, a first link part, and a second link part. And a moving rotation shaft for connecting the two. The restricting portion may include a first restricting portion configured to restrict the movement of the lead wire from the moving rotation shaft to the side opposite to the central portion side of the refrigerator main body.

Such a configuration can reduce the amount of bending and deflection of the lead wire and more reliably prevent the lead wire from being damaged. Therefore, such a configuration can provide a highly reliable refrigerator that can prevent damage to the lead wire and the like even when a hinge having a link mechanism is used and the door is pivotally supported.

Further, in the refrigerator according to an example of the present disclosure, the restriction unit restricts the movement of the lead wire in the depth direction of the refrigerator body from the hinge to the back side of the refrigerator body, and allows the movement of the lead wire in a predetermined direction. You may have the comprised 2nd control part.

Such a configuration can prevent the excessive portion of the lead wire generated by opening and closing the door from being caught in the hinge portion. Therefore, such a configuration can provide a highly reliable refrigerator that can prevent damage to the lead wire and the like even when a hinge having a link mechanism is used and the door is pivotally supported.

Therefore, even if it is an undercounter type refrigerator built in a system kitchen etc. by such a structure, without interfering with the apparatus installed adjacent to the refrigerator, for example, a dishwasher etc., the door 20 is made. Can be opened and closed.

The lead wire 79 (see FIG. 19) 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. . As shown in FIG. 21, the lead wire 79 from the operation display unit 23 is wired along the bottom surface of the door 20 to the lower hinge 75b. The lead wire 79 is drawn into the bottom surface of the refrigerator main body 1 through the through hole 80 (see FIG. 19) 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 place where the lead wire 79 is pulled into the refrigerator body 1. The end of the through hole 80 on the center side of the refrigerator body 1 is located on the opposite side of the center side of the refrigerator body 1 from the moving rotation shaft 757 in the state where the door 20 is closed. Furthermore, the end of the through hole 80 on the center side of the refrigerator main body 1 is located at the center of the line segment 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 side opposite to the center side.

The end of the through hole 80 opposite to the central part side of the refrigerator main body 1 is located closer to the central side of the refrigerator main body 1 than the main body side rotating 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 an extension line X of a line parallel to a virtual line passing through the center of the door 20 in the thickness direction when the door 20 is fully opened. It is desirable to be located above (see FIG. 19). In the present embodiment, an example in which the first restricting portion is provided in the hinge cover 78 as the through hole 80 is shown, but it may be provided directly in the refrigerator main body 1.

Further, the lead wire 79 drawn from the through hole 80 is held by a clip 81 provided on the bottom surface of the refrigerator main body 1. The clip 81 is a second restricting portion that restricts movement of the lead wire 79 in other directions without restricting movement of the lead wire 79 in a predetermined direction (for example, the Y direction in FIG. 19). The position of the clip 81 in the width direction of the refrigerator main body 1 is closer to the center of the refrigerator main body 1 than 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 the back side of the refrigerator body 1 from the lower hinge 75b (see FIG. 19).

The operation and effect of the door 20 of the refrigerator 90 configured as described above will be described below.

The door 20 of the refrigerator 90 of the present embodiment is pivotally supported on the refrigerator main body 1 by an upper hinge 75a and a lower hinge 75b. Moreover, in the door 20 of the refrigerator 90 of this Embodiment, the lead wire is drawn around using the lower hinge 75b part. Specifically, for example, as described above, the lead wire 79 that connects the operation display unit 23 provided on the upper portion of the door 20 to the control unit (not shown) provided on the refrigerator main body 1 connects the lower hinge 75b portion. Utilized, it is routed to the refrigerator body 1 side.

In the refrigerator 90 of the present embodiment, the lead wire 79 routed from the operation unit 71 to the control unit of the refrigerator main body 1 bends when the door 20 is opened and closed. 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 opened. In particular, when a hinge having a link mechanism is used, the required difference in the length of the lead wire between the closed state and the opened state becomes large. For these reasons, a load is applied to the lead wire 79 and the lead wire 79 may be disconnected.

However, in the present embodiment, the lead wire 79 is drawn into the bottom surface of the refrigerator main body 1 through the through hole 80 provided in the hinge cover 78 of the lower hinge 75b. The refrigerator 90 of the present embodiment is configured such that the lead-in position of the lead wire 79 is regulated by at least one of the through hole 80 and the clip 81. With such a configuration, 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 opened can be reduced. Further, even if the lead wire 79 extends and contracts due to the opening and closing of the door 20 and the length of the lead wire 79 changes, the remaining lead wire 79 contracts between the end of the door 20 and the lower hinge 75b. It can prevent being bitten.

That is, even if the door 20 is closed and the lead wire 79 is left in a surplus state, the lead wire 79 of the portion having the excess dimension is restricted from moving to the center side of the refrigerator main body 1 through the through hole 80. Further, when the clip 81 is provided through the through hole 80, the clip body 81 moves to the bottom surface side of the refrigerator main body 1 through the through hole 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 is greatly expanded and contracted, the load due to the bending of the lead wire 79 and the biting of the lead wire 79 are caused. It is suppressed and disconnection etc. can be prevented.

In particular, the through-hole 80 is configured to restrict the movement of the lead wire 79 from the moving rotation shaft 757 to the side opposite to the central portion side of the refrigerator main body 1. With such a configuration, the bending amount and the bending amount of the lead wire 79 can be reduced, and the damage to the lead wire 79 can be more reliably prevented.

The clip 81 is configured to restrict the movement of the lead wire 79 in the depth direction of the refrigerator main body 1 from the lower hinge 75b to the back side of the refrigerator main body 1, and in a predetermined direction of the lead wire 79 (for example, , In the Y direction in FIG. 19). With such a configuration, 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.

In particular, in the present embodiment, the through hole 80 is provided on an extension line X of a line parallel to a virtual line passing through the center in the thickness direction of the door 20 in a state where the door 20 is fully opened. With such a configuration, the excessive dimension portion of the lead wire 79 generated when the door 20 is closed slides through the through hole 80 and moves to the refrigerator main body side. Therefore, with such a configuration, bending at the hinge portion can be suppressed, and damage to the lead wire 79 can be more reliably prevented.

When the door 20 is attached to the inner plate 56 via a hinge, it is difficult to make the top surface of the outer box 6 and the upper surface of the door 20 parallel to each other, that is, it is difficult to ensure parallelism. is there. 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.

With such a configuration, even when the door 20 is pivotally supported by 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 is inclined with respect to the outer box 6 can be solved. Can do. Therefore, even if it is a case where it is used as a refrigerator with which the inclination of the door 20 is conspicuous like a built-in type, the inclination of the door 20 can be prevented reliably. Therefore, with such a configuration, the quality of the refrigerator is improved, the yield is increased, and cost reduction can be promoted.

The operation display unit 23 provided on the upper portion of the door 20 is installed such that the first pressing piece 74a and the second pressing piece 74b of the operation unit unit 71 are elastically contacted with the inner wall portion of the operation unit installation recess 70. Yes. With such a configuration, 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 capacitance at the time of the touch operation on the operation display unit 23 can be increased, and the operation quality on the operation display unit 23 can be improved.

Furthermore, the operation unit installation recess 70 in which the operation unit unit 71 is installed is provided with an inclined surface 73 a on the back side of the operation unit unit 71. With such a configuration, the gasket 62 can be mounted using a dead space generated behind the inclined surface 73a. That is, the operation unit 71 and the gasket 62 can be installed in an overlapping manner. With such a configuration, the installation space between the operation unit 71 and the gasket 62 can be reduced, and the center plate 21 can be enlarged correspondingly to increase the visibility.

Further, the gasket 62 provided on the inner plate 56 of the door 20 is provided so as to be positioned between the opening portions of the storage chambers 3 and 4 and the operation unit unit 71. With such a configuration, it is possible to prevent the cool air in the storage chambers 3 and 4 from flowing to the installation back surface portion of the operation unit unit 71 and cooling the installation back surface portion of the operation unit unit 71. Therefore, with such a configuration, it is possible to prevent a failure such as the occurrence of condensation due to excessive cooling of the operation unit 71.

Further, the refrigerator door 20 is configured such that a translucent central plate 21 is sandwiched and held between an outer plate 57 and an inner plate 56 of a frame-like edge frame 55. With such a configuration, the main components for holding and fixing the central plate 21 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 projecting toward the outer plate 57 and the rib projecting from the side surface forming the depression of the concave portion 60 on the inner plate 56. is there. However, in the present embodiment, the gasket holding member 61 is mounted in the recess 60 formed simultaneously with the molding of the inner plate 56 by the injection molding, in the configuration for holding the gasket of the inner plate 56 that is difficult to form by the injection molding. Is realized.

Therefore, although the number of parts increases 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, 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 the number of assembling steps and reducing the part manufacturing cost.

In the present embodiment, the convex portion 66 is configured to project into the opening portion of the concave portion 60. Further, in the present embodiment, the convex portion 66 is not a rib provided over the entire width of the concave portion 60 but is formed by protrusions provided at a predetermined interval. With such a configuration, the convex portion 66 can be easily formed by injection molding.

Further, the gasket holding member 61 has a gasket removal preventing rib 64 at the opening of the gasket holding recess 63. With such a configuration, the gasket 62 can be firmly fixed and held without dropping from the gasket holding recess 63. Therefore, with such a configuration, reliable sealing performance between the door 20 and the refrigerator main body 1 can be maintained. Further, the rib for preventing gasket removal 64 is configured to protrude into the opening portion of the gasket holding recess 63. Since the gasket removal preventing rib 64 is provided on the gasket holding member 61, it can be easily formed by extrusion.
