Description

[Technical Field]

[0001] The present disclosure relates to refrigerators. [Background technology]

[0002] Some refrigerators have built-in operation units for setting the temperatures of the refrigerator compartment and freezer compartment, operating and setting the ice-making device, and performing various other operations and settings. For example, Patent Document 1 discloses a refrigerator in which a unit (operation panel) including a circuit board and the like is arranged on a wall surface (side surface) inside the refrigerator. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-56500 A Summary of the Invention [Problem to be solved by the invention]

[0004] When the operating unit is disposed on the wall surface of the refrigerator interior as in Patent Document 1, a base component (board storage unit) having a recess for storing a control board and the like is provided on the wall surface of the refrigerator interior, and the operating unit is provided in the recess. Here, the outside (back side) of the base part is filled with urethane (foam insulation) by urethane foaming. When filling the foam insulation, a jig (mold) is set up so that it fits along the entire wall surface of the refrigerator interior. However, because the recess in the base part is recessed further outward than the wall surface, the stress (foaming pressure) generated when filling the urethane can cause the base part to deform and the recess to collapse. For this reason, it is necessary to support the base part from the inside (front side) of the recess when filling the urethane. The refrigerator described in Patent Document 1 is provided with a support member (reinforcing portion) that protrudes inward from the surface of the base part, and therefore, deformation of the base part when filled with urethane can be suppressed.

[0005] However, in order to store the control board in the recess of the base part (between the surface panel of the operation unit and the base part), it is necessary to provide a hole in the corresponding position of the support member, which results in a problem of reducing the effective area of ​​the control board. Furthermore, if the number of support members were increased to adequately prevent deformation (tilt) due to uneven foaming pressure applied to each part of the base part, the amount of wasted space would increase further, reducing the effective area of ​​the control board. For this reason, it was difficult to provide a sufficient number of support members. It is possible to consider fitting a separate small jig (placement jig) only into the recess of the base part to support the base part from the inside, but this method is not desirable because it makes the urethane filling operation complicated.

[0006] An object of the present disclosure is to suppress deformation of the base parts of the operation panel when filling with urethane in a refrigerator having an operation panel on a wall surface inside the refrigerator, in a simple manner without reducing the effective area of ​​the control board. [Means for solving the problem]

[0007] A base component according to one aspect of the present disclosure is disposed on the rear side of a front panel of an operating unit attached to an interior wall of a refrigerator. The operation unit includes the surface panel, the base component, and a control board disposed between the surface panel and the base component. The base part has a breakable support member that protrudes toward the surface panel. [Effects of the Invention]

[0008] According to one aspect of the present disclosure, in a refrigerator in which an operation panel is provided on a wall surface inside the refrigerator, deformation of a base component of the operation panel during urethane filling can be suppressed in a simple manner without reducing the effective area of ​​the control board.

[0010] Hereinafter, each embodiment of the present disclosure will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals, and their names and functions are also the same.

[0011] <Refrigerator> First, the overall configuration of a refrigerator 1 according to an embodiment will be described with reference to FIGS.

[0012] In this disclosure, the term "refrigerator" generally refers to a device that has an internal space (cooling compartment) that is kept at a temperature lower than the outside air temperature and can lower the temperature of stored items. The refrigerator may be, for example, a freezer. The refrigerator may have only one cooling compartment, or may have multiple cooling compartments. When a refrigerator has multiple cooling compartments, the multiple cooling compartments may include at least two of a refrigerator compartment, a freezer compartment, a vegetable compartment, a chilled compartment, a partial compartment, etc.

[0013] The refrigerator 1 includes an insulating box 5 (housing) as an insulating structure for insulating each storage space from the surroundings. The insulating box 5 includes an insulating layer, an outer box 52 that forms the outer shape of the refrigerator 1, an inner box 51 that forms the storage space (inner wall) of the refrigerator 1, and the like. The insulating layer includes a foam insulating material and a vacuum insulating material. The foam insulating material can be made of, for example, polyurethane foam (rigid urethane foam). The vacuum insulating material is a thin sheet-like or plate-like insulating material. The vacuum insulating material is arranged on, for example, the side, top, bottom, and back surfaces of the refrigerator 1.

[0014] In this specification, the surface on which a door (not shown) is provided (the surface on the front side of the insulated box body 5) is referred to as the front or front face of the refrigerator 1. Then, based on the arrangement of the refrigerator 1 when installed in a normal state with the front face as the reference, the respective faces of the refrigerator 1 are referred to as the back, top, bottom, and side faces. Also, the direction perpendicular to the front and back faces is referred to as the front-to-back direction, the direction perpendicular to the top and bottom faces is referred to as the up-down direction, and the direction perpendicular to both side faces is referred to as the width direction. Note that the orientation of each component that constitutes the refrigerator 1 may also be expressed based on the arrangement of the refrigerator 1.

[0015] The storage space formed by the insulated box 5 may be divided by a horizontally extending partition into an upper cooling compartment (refrigerating compartment 11) and other cooling compartments (vegetable compartment and freezing compartment) on the lower side. In this way, the insulated box 5 has cooling compartments (refrigerating compartment 11, vegetable compartment, freezing compartment, etc.). However, the arrangement of each cooling compartment is not limited to this.

[0016] For example, a space (machine room) for arranging a compressor is provided on the lower back side of the insulated box 5. Since the temperature inside the machine room rises when the cooling device is operated, the machine room is arranged outside the insulated box 5. The cooling device includes a refrigeration cycle, a control unit, etc. The refrigeration cycle is composed of a compressor, a condenser, an expander, an evaporator, etc., which are connected via refrigerant pipes through which a refrigerant flows.

[0017] [Operation unit] The refrigerator 1 of this embodiment includes an inner box 51 forming an inner wall (the inner surface of the inner box 51: the side wall 51a inside the refrigerator compartment 11), and an operating unit 2 attached to the inner wall. That is, the operating unit 2 is attached to the interior wall of the refrigerator 1.

[0018] FIG. 16 shows the operation unit 2 disassembled into its components. The operation unit 2 is A surface panel 21; a base component 22 disposed on the rear side of the surface panel 21; and a control board 23 disposed between the surface panel 21 and the base component 22.

[0019] 16 also shows a harness (wiring) 25 connected to the control board 23 via the connector 24.

[0020] (Front panel) The surface of the operation unit 2 is formed by a surface panel 21. The surface panel 21 is arranged along the side wall 51a of the refrigerator compartment 11. The surface panel 21 is provided with a plurality of operation buttons 31 for setting the temperature of each storage compartment such as the refrigerator compartment 11, operating and setting the ice maker, and performing various other operations and settings (see FIG. 4).

[0021] The surface panel 21 is obtained by, for example, molding a resin material into a predetermined shape. The rear surface of the front panel 21 may be provided with a space for storing the control board 23, the harness 25, and the like.

[0022] Additionally, a plurality of claws (such as the second claws 33) are provided on the side wall 34d of the surface panel 21. These claws are fitted into various locations on the base component 22, thereby fixing the surface panel 21 to the base component 22 (see FIGS. 15 and 16).

[0023] (control board) The control board 23 is disposed between the surface panel 21 and the base component 22. That is, the control board 23 is sandwiched between the surface panel 21 and the base component 22. The control board 23 has a generally rectangular flat plate shape. Various electronic circuits are provided on the surface of the control board 23.

[0024] For example, the connector 24 is attached to a predetermined position on a side edge (for example, the side edge 23d) of the flat control board 23.

[0025] (base part)

[0026] 5 to 7, base component 22 is a component arranged on the rear side of face panel 21 in operation unit 2 attached to the interior wall of the refrigerator (the inner surface of inner box 51: side wall 51a inside refrigerator compartment 11). The refrigerator of this embodiment is a refrigerator that uses (is manufactured using) the following base component 22.

[0027] The base component 22 is attached to an opening 55 formed in the inner box 51 of the heat-insulating box body 5, and a space (recess 22a) capable of accommodating the control board 23 and part of the surface panel 21 is formed therein. The base part 22 has, for example, a flange portion 42 on the outer periphery of the recessed portion 22a. The base part 22 is attached to the opening 55 of the inner box 51 so that the flange portion 42 of the base part 22 is fixed to the back surface (outer surface) around the opening 55 of the inner box 51.

[0028] In this embodiment, the base component 22 (recess 22a) has a breakable support member 221 that protrudes toward the surface panel 21 side.

[0029] In the past (Patent Document 1), holes were drilled in the substrate at the locations corresponding to the support members 221, which posed a problem in that electronic components could not be placed in those locations. In particular, increasing the number of support members 221 to prevent deformation due to foaming pressure increases the number of holes in the substrate, making it impossible to use the substrate surface effectively. In contrast, in this embodiment, the support member 221 can be broken off, so even if a support member 221 is provided to support the base component 22 from the inside during urethane filling, the support member 221 can be simply broken off after urethane filling, eliminating the need to provide a hole in the board for passing the support member 221 through. This makes it possible to ensure the effective area of ​​the control board. It is also possible to increase the number of support members 221.

[0030] The base component 22 having the support member 221 can be produced, for example, by molding a resin material into a predetermined shape. In the refrigerator 1 product, the support member 221 is broken off from the base part 22, but traces of the support member 221 being broken off can be confirmed by observing or analyzing the surface of the base part 22.

[0031] The shape of the support member 221 of the base component 22 is not particularly limited as long as it is a shape that can support the base component 22 from the inside so as to prevent the base component 22 from being deformed by the foaming pressure when the foam insulation material is filled. In this embodiment, the support member 221 is provided in a columnar shape standing upright from the bottom surface of the base component 22.

[0032] The base component 22 may have a harness storage section 43 for storing the harness 25 connected to the control board 23 via the connector 24. The harness storage section 43 is provided in one area of ​​the recess 22a of the base component 22, for example. With the operating unit 2 attached to the side wall 51 a of the refrigerator compartment 11 , the harness 25 is stored in the harness storage section 43 . In this embodiment, the harness storage section 43 is located at the back side of the refrigerator compartment 11 (the side farther from the opening of the insulated box body 5) in the recess 22a of the base part 22 (the opening 55 of the side wall 51a) (see Figure 5).

[0033] The direction in which the support member 221 is most likely to fold is preferably the opposite direction (direction D) to the harness storage section 43 (see FIG. 7).

[0034] If the harness storage section 43 is located in the direction in which the support member 221 is folded, there is a possibility that fragments of the support member 221 may get into the harness storage section 43 and become difficult to remove, but if the direction in which the support member 221 is folded is opposite to the harness storage section 43, it is possible to prevent fragments of the support member 221 from getting into the harness storage section 43.

[0035] The shape that determines the easy-to-fold direction of support member 221 is not particularly limited, but an example is a D-shaped cross section (see FIG. 7) in which the side wall of support member 221 facing the easy-to-fold direction is a flat surface and tapers toward the easy-to-fold direction. As a result, when a worker breaks off support member 221, the worker is less likely to hurt their fingers if they press against the flat surface, so this flat surface naturally becomes the pressing surface that is pressed by the fingers, and support member 221 is folded in direction D. Note that the pressing surface is not limited to a flat surface, and it may be any surface that applies less pressure to the fingers, such as a surface of the side wall facing the easy-to-fold direction that has a greater curvature than the surface of the side wall facing the easy-to-fold direction.

[0036] The support member 221 may have a columnar shape, for example, as shown in Fig. 7. In this case, the base part 22 with the support member 221 can be easily manufactured by integral molding.

[0037] As shown in FIGS. 8(a) and 8(b), the support member 221 may have a large cross-sectional area on the distal end side 221a and a small cross-sectional area on the proximal end side 221b.

[0038] If the area of ​​the portion of the tip side 221a that abuts against the jig 6 is small, the base part 22 may not be able to be supported against the foaming pressure, and the base part 22 may become deformed. However, by increasing the cross-sectional area of ​​the tip side 221a (particularly the very tip) of the support member 221, the base part 22 can be supported more stably, and deformation of the base part 22 can be more reliably prevented. However, if the cross-sectional area of ​​the base end side 221b is also increased, the support member 221 becomes thicker, making it difficult to break off, and there is a possibility that the base portion will remain broken off. However, by making the cross-sectional area of ​​the base end side 221b relatively smaller (thinner), the support member 221 can be broken off more reliably.

[0039] Furthermore, it is more preferable that the support member 221 has a shape that allows the harness 25 to be easily fixed. For example, as shown in (a) and (b) of Figure 8, the tip side 221a of the support member 221 extends in one direction bent relative to the protruding direction of the base side 221b, thereby providing a claw-like hook portion, which makes it easy to hook and fix the harness 25 on this portion.

[0040] It is preferable that a plurality of support members 221 are provided in each of the vertical and horizontal directions of the base component 22 (in a plan view). This is to prevent the base component 22 from tilting in the case where foaming pressure when filling the insulating material is applied unevenly to the back surface of the base component 22. In the past, when providing a large number of support members in this manner, it was necessary to provide a large number of holes in the substrate according to the number of support members. However, in this embodiment, since a breakable support member 221 is used, it is possible to provide a large number of support members. When multiple support members 221 are provided on a base component, it is preferable that the pressing surfaces of the multiple support members 221 face the same direction. This allows the direction in which the worker applies force with their fingers to be limited to one direction when breaking off the support members 221, eliminating the need to change the orientation of the fingers and allowing the multiple support members 221 to be broken off efficiently.

[0041] Furthermore, it is preferable that the support member 221 is disposed at a position where at least the harness 25 can be fixed. Specifically, for example, as shown in FIG. 6, it is preferable that the support member 221 is provided at a position at least close to the outlet of the harness 25 (a position close to the side edge 23d of the control board 23 to which the connector 24 is attached). As shown in FIG. 6, it is preferable that some of the support members 221, 222, are arranged so that the harness 25 is hooked between the two support members 221, 222 and the connector 24 is housed in the recess 22a.

[0042] To prevent the connector 24 and the harness 25 from being pinched between the jig 6 and the interior wall (side wall 51a) and being damaged when the insulating material is filled, it is desirable to fix the connector 24 and the harness 25 within the recess 22a (so that they do not protrude from the opening 55). Conventionally, temporary fixing has been performed using tape or the like, but by making it possible to fix the harness 25 with the support member 221, the operation is simplified and tape for temporary fixing is no longer necessary.

[0043] (Refrigerator manufacturing method) The manufacturing method of this embodiment is a method for manufacturing a refrigerator that includes an inner box 51 that forms an inner wall of the refrigerator, and an operating unit 2 that is attached to the inner wall of the refrigerator. As described above, the operation unit 2 includes the surface panel 21, the base component 22 arranged on the back side of the surface panel 21, and the control board 23 arranged between the surface panel 21 and the base component 22.

[0044] The manufacturing method of this embodiment includes a heat insulating material filling step and a support member removing step (a step of breaking off the support member 221 from the base part 22 after the heat insulating material filling step). Furthermore, the method includes a step of attaching the base part before the step of filling the insulating material, and a step of assembling the operating part after the step of removing the support member.

[0045] (Base part installation process) When attaching the operating unit 2 to the refrigerator 1, first, the base part 22 is attached to the inner box 51 (before the step of filling the heat insulating material).

[0046] Specifically, the recess 22a of the base part 22 is aligned with the opening 55 of the inner box 51, and the flange part 42 of the base part 22 is attached to the back surface of the inner box 51 with tape or the like. At this time, the harness 25 is passed through the heat-insulating box 5 and is pulled out from the back side of the harness storage section 43 of the base part 22 to the recess 22a. A connector 24 is attached to the tip of the harness 25, and is pulled out together with the harness 25 into the recess 22a and fixed by a part of the support member 221 so as not to move.

[0047] 6, a recess 22a in which the surface panel 21 and the like are disposed is formed in the opening 55 of the side wall 51a. In the base component 22 attached to the side wall 51a, the harness storage section 43 is located at the back side of the refrigerator compartment 11.

[0048] (insulation material filling process) 9 to 12, in the insulating material filling process, a base part 22 having a support member 221 (which can be broken off and protrudes toward the surface panel 21) is positioned on the back side of the surface panel 21, and then a foam insulating material such as foamed urethane is filled on the outside of the inner box 51 (the space 53 between the inner box 51 and the outer box 52) (see FIG. 12). The insulating material filling step can be carried out by injecting foam insulating material (uncured) from injection head 7 while jig 6 (mold) is inserted into the storage space formed by insulating box body 5 (see Figures 9 to 11). The injected foam insulating material flows through space 53 between inner box 51 and outer box 52, as shown by the dotted arrow in Figure 11, and fills the entire space 53.

[0049] In the step of filling the heat insulating material (when the jig 6 is inserted into the heat insulating box 5), the support member 221 preferably has a length that reaches the same height as the inner surface of the inner box 51. 12, it is preferable that the tip of the support member 221 protrudes to a position that is flush with the wall surface of the interior of the refrigerator (the inner surface of the inner box 51: the side wall 51a). In this case, in the base part 22 alone, the tip of the support member 221 is formed to be at the same height as the flange portion 42 or slightly higher than the flange portion 42. This allows the surface of the jig 6 supporting the opening 55 in the side wall 51a and the surface of the jig 6 supporting the periphery of the opening 55 to be flush with each other, making it easy to insert the jig 6 into the inner box 51.

[0050] (Support member removal process) The support member removing step is performed after the heat insulating material filling step and before assembling the operation unit 2 (that is, before the control board 23 and the surface panel 21 of the operation unit 2 are attached to the base component 22). In the support member removing step, the support member 221 is broken off from the base component 22. The operation unit 2 cannot be assembled while the support member 221 remains (FIG. 13), but by breaking off the support member 221, the operation unit 2 can be assembled (FIG. 14).

[0051] (Operation unit assembly process) 15 and 16, in the operation unit assembling process, control board 23 and surface panel 21 are attached to recess 22a of base component 22 (opening 55 of side wall 51a).

[0052] Specifically, first, the control board 23 is attached to the rear surface side of the front panel 21. When attaching the front panel 21 with the control board 23 attached to the side wall 51a, the connector 24 at the end of the harness 25, which is drawn into the recess 22a of the base part 22, is attached to a predetermined position on the control board 23 in advance. The harness 25 connected to the control board 23 is connected to the main body of the refrigerator 1.

[0053] The base component 22 is provided with fitting portions into which the respective claw portions (first claw portion and second claw portion 33) of the surface panel 21 are fitted.

[0054] 15, the surface panel 21 is first fitted into the recess 22a from the rear side edge connected to the harness 25. That is, a first claw portion (not shown) provided on the rear side wall portion of the surface panel 21 is inserted into the fitting portion 41 of the base component 22. At this time, the harness storage section 43 is provided on the side edge on the far side of the opening 55 (the recess 22a of the base part 22), and the harness 25 is guided toward the harness storage section 43.

[0055] Thereafter, the surface panel 21 is rotated around the rear side edge of the surface panel 21 as a rotation axis. Then, the side wall portion 34d on the front side of the surface panel 21 (the front side of the insulated box 5) is pressed into the recess 22a, and the second claw portion 33 provided on the side wall portion 34d on the front side of the surface panel 21 is fitted into the fitting portion of the base component 22.

[0056] In this manner, the control board 23 and the surface panel 21 are attached to the base component 22, and the operation unit 2 is assembled.

[0057] As described above, the control board 23 may be first incorporated into the space on the back side of the surface panel 21, and then the surface panel 21 with the control board 23 attached to the base component 22; alternatively, the control board 23 may be first installed in the recess 22a or the like of the base component 22, and then the surface panel 21 may be attached to the base component 22 with the control board 23 attached to it.
