Description

Technical Field

[0001] The present disclosure relates to a base component, a refrigerator, and a manufacturing method. Background Art

[0002] The refrigerator is equipped with an operation unit for setting the temperature of the refrigerator compartment and the freezer compartment, operating and setting an ice maker, and performing other various operations and settings.

[0003] For example, Japanese Patent Application Laid-Open No. 2019-56500 discloses a refrigerator in which a unit (operation panel) including a substrate and the like is arranged on a wall surface (side surface) inside the refrigerator. Summary of the Invention

[0004] As disclosed in Japanese Patent Application Publication No. 2019-56500, when the operating unit is arranged on the wall surface inside the box, a base component (substrate storage portion) is provided on the wall surface inside the box. The base component has a recess for storing a control substrate, etc., and the operating unit is provided on the recess. Here, polyurethane (foaming insulation material) is filled on the outside (back side) of the base component by polyurethane foaming. When filling the foaming insulation material, a jig (mold) is provided along the entire wall surface inside the box. However, since the recess of the base component is more recessed to the outside than the wall surface, the base component is likely to be deformed and the recess is crushed due to the stress (foaming pressure) during polyurethane filling. Therefore, when filling with polyurethane, it is necessary to support the base component from the inside (front side) of the recess.

[0005] In the refrigerator described in Japanese Patent Application Laid-Open No. 2019-56500, since a support member (reinforcement portion) protruding inward from the surface of the base member is provided, deformation of the base member during polyurethane filling can be suppressed.

[0006] However, in order to accommodate the control board in the recess of the base member (between the surface panel of the operating unit and the base member), a hole must be provided at a position corresponding to the support member, which reduces the effective area of ​​the control board.

[0007] Furthermore, if the number of support members is increased to fully prevent deformation (tilting) caused by uneven foaming pressure applied to various locations of the base member, wasted space will increase further, reducing the effective area of ​​the control substrate. Therefore, it is difficult to provide a sufficient number of support members.

[0008] It is also conceivable to simply insert another small jig (placement jig) into the recess of the base member to support the base member from the inside, but this method is not advisable because the polyurethane filling operation becomes complicated.

[0009] The present disclosure aims to suppress deformation of a base member of a refrigerator having an operation panel provided on a wall surface thereof by a simple method when filling the refrigerator with polyurethane without reducing the effective area of ​​a control substrate.

[0010] One aspect of the present disclosure relates to a base component, disposed on the back side of a front panel in an operating unit mounted on the inner wall of a refrigerator. The operating unit includes the front panel, the base component, and a control substrate disposed between the front panel and the base component. The base component includes a foldable support member protruding toward the front panel.

[0011] According to one aspect of the present disclosure, in a refrigerator having an operation panel provided on a wall surface inside the refrigerator, deformation of a base member of the operation panel during polyurethane filling can be suppressed by a simple method without reducing the effective area of ​​a control board.

[0028] Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. In the following description, identical components are denoted by identical reference numerals, and their names and functions are also identical.

[0029] Refrigerator

[0030] First, refer to Figures 1 to 3 , the overall structure of the refrigerator 1 of this embodiment is described.

[0031] In this disclosure, the term "refrigerator" refers to any refrigerator that has an interior space (cooling chamber) at a temperature lower than the outside air temperature and is capable of lowering the temperature of stored items. A refrigerator may also be, for example, a freezer. A refrigerator may have only one cooling chamber or multiple cooling chambers. If a refrigerator has multiple cooling chambers, the multiple cooling chambers may include at least two of a refrigeration chamber, a freezer chamber, a vegetable chamber, a zero-degree chamber, a partial freezer, or the like.

[0032] The refrigerator 1 has an insulating box body 5 (shell) as an insulating structure for insulating each storage space from the surroundings. The insulating box body 5 has an insulating layer, an outer box 52 forming the outer shape of the refrigerator 1, an inner box 51 forming the storage space (inner wall of the box) of the refrigerator 1, etc. The insulating layer includes foam insulation materials and vacuum insulation materials. The foam insulation material can be formed of, for example, foamed polyurethane (rigid polyurethane foam). The vacuum insulation material is a thin plate or plate-shaped insulation material. The vacuum insulation material is arranged on, for example, the side, top, bottom and back of the refrigerator 1.

[0033] In this specification, the surface on which the door (not shown) is provided (the surface on the side of the opening of the heat-insulating box body 5) is referred to as the front or front face of the refrigerator 1. Furthermore, based on the configuration of the refrigerator 1 set in a normal state, with the front face as a reference, the surfaces of the refrigerator 1 are referred to as the back face, top face, bottom face, and side face. In addition, 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 the two side faces is referred to as the width direction. In addition, the directions of the various components constituting the refrigerator 1 are sometimes also expressed based on the configuration of the refrigerator 1.

[0034] The storage space formed by the insulated box 5 can also be divided into an upper cooling chamber (refrigerated compartment 11) and other cooling chambers (vegetable compartment and freezer compartment) on the lower side by a horizontally extending partition. In this way, the insulated box 5 has cooling chambers (refrigerated compartment 11, vegetable compartment, freezer compartment, etc.). The arrangement of the cooling chambers is not limited to this.

[0035] For example, a space (machine room) for accommodating a compressor is provided on the back side below the insulated box 5. Furthermore, because the temperature inside the machine room rises as the cooling device operates, the machine room is located outside the insulated box 5. The cooling device includes a refrigeration cycle, a control unit, and other components. The refrigeration cycle consists of a compressor, a condenser, an expander, an evaporator, and other components connected by refrigerant pipes through which the refrigerant circulates.

[0036] [Operation Department]

[0037] The refrigerator 1 of this embodiment includes an inner box 51 forming an inner wall (inner surface of the inner box 51: side wall 51a in the refrigerating chamber 11) and an operation unit 2 attached to the inner wall.

[0038] That is, the operation unit 2 is attached to the inner wall of the refrigerator 1 .

[0039] Figure 16 The operation unit 2 is shown in a state disassembled into its components.

[0040] The operating unit 2 includes:

[0041] Surface panel 21;

[0042] a base member 22 disposed on the back side of the surface panel 21;

[0043] The control substrate 23 is disposed between the surface panel 21 and the base member 22 .

[0044] in addition, Figure 16 Also shown is a wiring harness (wiring) 25 connected to the control board 23 via a connector 24 .

[0045] (Surface panel)

[0046] 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 refrigeration chamber 11. A plurality of operation buttons 31 (see Figure 4 ), the operation button 31 is used to set the temperature of each storage room such as the refrigerator room 11, operate and set the ice making device, and other various operations and settings.

[0047] The front panel 21 is formed of, for example, a resin material into a predetermined shape. In addition, a space for accommodating the control board 23, the harness 25, and the like may be provided on the back side of the front panel 21.

[0048] In addition, a plurality of claws (such as the second claws 33) are provided on the side wall portion 34d of the surface panel 21. By fitting these claws into various locations of the base member 22, the surface panel 21 is fixed relative to the base member 22 (see Figure 15 、 Figure 16 ).

[0049] (Control board)

[0050] The control board 23 is arranged between the surface panel 21 and the base member 22. That is, the control board 23 is in a state of being sandwiched between the surface panel 21 and the base member 22.

[0051] The control board 23 has a substantially rectangular flat plate shape. Various electronic circuits are provided on the surface of the control board 23 .

[0052] For example, the connector 24 is mounted at a predetermined position on a side edge (for example, the side edge 23 d ) of the flat-plate-shaped control substrate 23 .

[0053] (Base components)

[0054] Reference Figures 5 to 7 The base member 22 is a member disposed on the back side of the surface panel 21 in the operation unit 2 mounted on the inner wall of the refrigerator (the inner surface of the inner box 51: the side wall 51a in the refrigerating chamber 11).

[0055] The refrigerator of the present embodiment is a refrigerator using (manufactured using) a base member 22 described below.

[0056] The base member 22 is attached to the opening 55 formed in the inner box 51 of the heat-insulating box body 5 , and forms a space (recessed portion 22 a ) capable of accommodating the control board 23 and a part of the front panel 21 .

[0057] The base member 22 has a flange portion 42 on the outer periphery of the recess 22a. The base member 22 is mounted on the opening 55 of the inner box 51 so that the flange portion 42 is fixed to the back surface (outer surface) around the opening 55 of the inner box 51.

[0058] In the present embodiment, the base member 22 (recessed portion 22 a ) includes a foldable support member 221 that protrudes toward the front panel 21 .

[0059] Conventional designs (Japanese Patent Application Publication No. 2019-56500) have holes in the substrate corresponding to the support member 221, but this has made it difficult to place electronic components in this area. In particular, adding support member 221 to prevent deformation due to foaming pressure increases the number of holes in the substrate, preventing efficient use of the substrate surface.

[0060] In contrast, in this embodiment, since the support members 221 are foldable, even if the support members 221 are provided to support the base member 22 from the inside during polyurethane filling, the support members 221 can simply be folded out after polyurethane filling. Therefore, there is no need to provide a hole in the substrate for the support members 221 to pass through. This ensures that the effective area of ​​the substrate can be controlled. Furthermore, the number of support members 221 can be increased.

[0061] The base member 22 including the support member 221 can be produced by molding a resin material into a predetermined shape, for example.

[0062] In the product of the refrigerator 1 , the support member 221 is folded off from the base member 22 , but traces of the folding of the support member 221 can be confirmed by surface observation or surface analysis of the base member 22 .

[0063] The shape of the support member 221 of the base member 22 is not particularly limited as long as it can support the base member 22 from the inside in a manner that prevents the base member 22 from deforming due to the foaming pressure when the foam insulation material is filled. In this embodiment, the support member 221 is provided upright in a columnar shape from the bottom surface of the base member 22.

[0064] The base member 22 may include a harness storage portion 43 for storing the harness 25 connected to the control board 23 via the connector 24. The harness storage portion 43 is provided in one region of the recess 22a of the base member 22, for example.

[0065] In a state where the operation unit 2 is attached to the side wall 51 a of the refrigeration compartment 11 , the wire harness 25 is housed in the wire harness housing portion 43 .

[0066] In addition, in this embodiment, the harness storage portion 43 is located on the inner side of the refrigerator compartment 11 (the side away from the opening of the heat-insulating box body 5) in the recessed portion 22a of the base member 22 (the opening portion 55 of the side wall 51a) (see Figure 5 ).

[0067] The direction in which the support member 221 is easily folded is preferably the direction (direction D) opposite to the harness housing portion 43 (see Figure 7 ).

[0068] If there is a wire harness storage portion 43 in the direction of the bent support member 221, fragments of the support member 221 may enter the wire harness storage portion 43 and be difficult to remove. However, when the direction of the bent support member 221 is opposite to the wire harness storage portion 43, the fragments of the support member 221 can be prevented from entering the wire harness storage portion 43.

[0069] The shape of the direction in which the support member 221 is easily folded is not particularly limited. For example, the side wall of the support member 221 facing the direction is made flat, and the cross section is D-shaped and tapered toward the direction (see FIG. Figure 7 ). Thus, when the operator folds the support member 221, the fingers are less likely to feel pain by pressing against the flat surface. Therefore, the flat surface naturally becomes the pressing surface pressed by the fingers, and the support member 221 is folded in the direction D. In addition, the pressing surface is not limited to a flat surface. The surface of the side wall facing the direction of easy folding can be any surface that has a greater curvature than the surface of the side wall facing the direction of easy folding, so as to reduce the pressure on the fingers.

[0070] The shape of the support member 221 can be, for example, Figure 7 In this case, when the base member 22 with the support member 221 is manufactured by integral molding, the manufacturing becomes easy.

[0071] like Figure 8 As shown in (a) and (b) of FIG. 1 , the cross-sectional area of ​​the distal end side 221 a of the support member 221 may be large, and the cross-sectional area of ​​the proximal end side 221 b may be small.

[0072] If the area of ​​the portion of the front end side 221a that contacts the jig 6 is small, the base component 22 cannot be supported relative to the foaming pressure, and the base component 22 may be deformed. However, by increasing the cross-sectional area of ​​the front end side 221a (especially the front end) of the support component 221, the base component 22 can be supported more stably and deformation of the base component 22 can be more reliably prevented.

[0073] However, if the cross-sectional area of ​​the base end side 221b becomes larger, it becomes thicker and difficult to fold the support component 221, and the root part may be broken and remain. However, by making the cross-sectional area of ​​the base end side 221b relatively smaller (thinner), the support component 221 can be folded more reliably.

[0074] Furthermore, the support member 221 is preferably shaped so as to facilitate fixing of the wire harness 25 .

[0075] For example, Figure 8 As shown in (a) and (b), by extending the front end side 221a of the support member 221 in one direction of the protrusion direction relative to the base end side 221b, a claw-shaped hook portion can also be provided to easily hook and fix the wire harness 25 at this portion.

[0076] Preferably, a plurality of support members 221 are provided in the longitudinal direction and the lateral direction (in a plan view) of the base member 22 .

[0077] The purpose is to prevent the base member (22) from tilting in the event that the foaming pressure during filling of the heat insulating material may be unevenly applied to the back surface of the base member 22. In the case of providing multiple support members, it has been necessary to provide multiple holes in the base plate in accordance with the number of holes. However, in this embodiment, a foldable support member 221 is used, so that multiple support members can be provided.

[0078] When multiple support members 221 are provided on the base member, it is preferred that the pressing surfaces of the multiple support members 221 face the same direction. This allows the operator to apply force to the fingers in a single direction when folding the support members 221, eliminating the need to change the direction of the fingers and enabling efficient folding of the multiple support members 221.

[0079] Furthermore, it is preferable that the support member 221 is disposed at least at a position where the wire harness 25 can be fixed.

[0080] Specifically, for example, Figure 6 As shown, the support member 221 is preferably provided at least at a position close to the removal port of the wire harness 25 (a position close to the side edge 23d of the control board 23 to which the connector 24 is mounted).

[0081] In addition, if Figure 6 As shown, it is preferable that a part of the support member 222 of the support member 221 is arranged so that the wire harness 25 is hung between the two support members 221 and 222 and the connector 24 is accommodated in the recessed portion 22 a.

[0082] When filling the insulation material, in order to prevent the connector 24 and the wiring harness 25 from being damaged by being sandwiched between the jig 6 and the inner wall of the box (side wall 51a), it is preferable to fix the connector 24 and the wiring harness 25 in the recess 22a (not protruding from the opening 55). Conventionally, temporary fixation is performed using a band or the like. However, by being able to fix the wiring harness 25 using the support member 221, the operation is simplified and the use of a band for temporary fixation is no longer necessary.

[0083] (Method for manufacturing refrigerator)

[0084] The manufacturing method of the present embodiment is a method for manufacturing a refrigerator including an inner box 51 forming an inner wall of the box and an operation unit 2 attached to the inner wall of the box.

[0085] As described above, the operation unit 2 includes the surface panel 21 , the base member 22 disposed on the rear surface side of the surface panel 21 , and the control substrate 23 disposed between the surface panel 21 and the base member 22 .

[0086] The manufacturing method of this embodiment includes a heat insulating material filling step and a support member 221 removal step (a step of folding the support member 221 from the base member 22 after the heat insulating material filling step).

[0087] Furthermore, the base member installation step is included before the heat insulating material filling step, and the operation unit assembly step is included after the support member removal step.

[0088] (Base component installation process)

[0089] When the operation unit 2 is mounted on the refrigerator 1, first (before the heat insulating material filling step) the base member 22 is mounted on the inner box 51 in advance.

[0090] Specifically, the recessed portion 22a of the base member 22 is aligned with the opening 55 of the inner box 51, and the flange portion 42 of the base member 22 is attached to the back surface of the inner box 51 using tape or the like.

[0091] At this time, the wire harness 25 passes through the heat-insulating box 5 and is led out to the recess 22a from the back side of the wire harness storage portion 43 of the base member 22. The connector 24 is attached to the front end of the wire harness 25 and is led out to the recess 22a together with the wire harness 25 and is fixed by a portion of the support member 221 so as not to move.

[0092] Therefore, if Figure 6 As shown, the opening 55 of the side wall 51a forms a recess 22a for arranging the front panel 21 and the like. Furthermore, the harness storage portion 43 is located on the back side of the refrigeration compartment 11 in the base member 22 attached to the side wall 51a.

[0093] (Thermal insulation material filling process)

[0094] Reference Figures 9 to 12 In the heat insulating material filling process, the base member 22 having the foldable support member 221 (which protrudes toward the surface panel 21) is placed at a position on the back side of the surface panel 21, and the outer side of the inner box 51 (the space 53 between the inner box 51 and the outer box 52) is filled with a foamed heat insulating material such as polyurethane foam (see Figure 12 ).

[0095] The heat insulating material filling step can be implemented by injecting the foam heat insulating material (uncured) from the injection head 7 while the jig 6 (mold) is inserted into the storage space formed by the heat insulating box 5 (see Figures 9 to 11). In addition, injected foam insulation materials such as Figure 11 As shown by the dotted arrows, the liquid flows into the space 53 between the inner box 51 and the outer box 52 and fills the entire space 53.

[0096] In the heat insulating material filling step (in a state where 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 .

[0097] That is, Figure 12 As shown, it is preferred that the front end of the support member 221 protrudes to a position that is flush with the wall surface inside the box (the inner surface of the inner box 51: the side wall 51a). In this case, in the base member 22 alone, the front end of the support member 221 is formed to be the same height as the flange portion 42 or slightly higher than the flange portion 42.

[0098] Thus, the surface of the jig 6 supporting the opening 55 of the side wall 51 a and the surface of the jig 6 supporting the periphery of the opening 55 can be flush with each other, and the jig 6 can be easily inserted into the inner box 51 .

[0099] (Support member removal process)

[0100] The support member removal step is performed after the heat insulating material filling step and before assembling the operation unit 2 (ie, before attaching the control board 23 and the surface panel 21 of the operation unit 2 to the base member 22 ).

[0101] In the support member removing step, the support member 221 is folded off from the base member 22 .

[0102] Although the operating unit 2 cannot be assembled with the support member 221 remaining, Figure 13 ), but by folding the support member 221, the operation portion 2 ( Figure 14 ).

[0103] (Operation unit assembly process)

[0104] Reference Figure 15 as well as Figure 16 In the operation unit assembly process, the control board 23 and the surface panel 21 are mounted in the recessed portion 22 a (the opening 55 of the side wall 51 a ) of the base member 22 .

[0105] Specifically, the control board 23 is first mounted on the back side of the front panel 21. When the front panel 21 with the control board 23 mounted thereon is mounted on the side wall 51a, the connector 24 at the front end of the wiring harness 25, which is led into the recessed portion 22a of the base member 22, is pre-installed at a predetermined position on the control board 23. Furthermore, the wiring harness 25 connected to the control board 23 is connected to the main body of the refrigerator 1.

[0106] The base member 22 is provided with fitting portions into which the claws (the first claws and the second claws 33 ) of the surface panel 21 are fitted.

[0107] like Figure 15 As shown, the front panel 21 is first fitted into the recess 22a from the rear side edge connected to the harness 25. Specifically, a first claw (not shown) provided on the rear side wall of the front panel 21 is inserted into the fitting portion 41 of the base member 22.

[0108] At this time, the harness storage portion 43 is provided on the side end side on the inner side of the opening portion 55 (the recessed portion 22 a of the base member 22 ), and the harness 25 is guided to the harness storage portion 43 .

[0109] Then, the surface panel 21 is rotated using the side edge of the inner side of the surface panel 21 as the rotation axis. Furthermore, the side wall portion 34d on the front side of the surface panel 21 (on the side of the opening of the heat-insulating box body 5) is pressed into the recessed portion 22a, and the second claw portion 33 provided on the side wall portion 34d on the front side of the surface panel 21 is inserted into the insertion portion of the base member 22.

[0110] In this manner, the control substrate 23 and the surface panel 21 are mounted on the base member 22 , and the operation unit 2 is assembled.

[0111] In addition, as described above, the control substrate 23 can be first installed in the space on the back side of the surface panel 21, and then the surface panel 21 with the control substrate 23 can be installed on the base component 22. In addition, the control substrate 23 can be first set in the recess 22a of the base component 22, and then the surface panel 21 can be installed on the base component 22 with the control substrate 23.

[0112] [Summarize]

[0113] The base component (e.g., base component 22) involved in one aspect of the present disclosure is arranged on the back side of a surface panel (e.g., surface panel 21) in an operating part (e.g., operating part 2) installed on the inner wall (e.g., side wall 51a) of a refrigerator (e.g., refrigerator 1).

[0114] The operation unit includes a surface panel, a base member, and a control substrate (for example, control substrate 23 ) disposed between the surface panel and the base member 22 .

[0116] In one aspect of the present disclosure, the support member is a columnar member erected on the bottom surface of the base member. The curvature of the pressing surface of the side wall of the support member, which faces the direction for easy folding, is preferably greater than the curvature of the flat surface or other surface.
