Description

Technical Field

[0001] Embodiments of the present invention relate to refrigerators. Background Technology

[0002] Conventionally, in refrigerators, shelves for storing items are supported by so-called reinforcing ribs protruding from the inner wall of the storage compartment. Regarding such shelf support structures, there are configurations that allow adjustment of the height or support position of the support member according to user preference, or that allow easy installation and removal of the support member. For example, in Patent Document 1, an inner component of the refrigerator with the support member and an outer component for fixing it to the inner wall of the storage compartment are arranged to clamp the inner wall, and the support member is detachably configured relative to the inner component.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2024-77243

[0004] However, the inner and outer components of the aforementioned structure overlap with each other across the inner wall of the storage compartment, resulting in an increase in volume in the thickness direction, which may lead to a decrease in the internal volume of the box or the volume of the insulation material on the outside of the box. Summary of the Invention

[0005] Therefore, a refrigerator is provided that, in a structure having an inner mounting member and an outer mounting member for mounting the support member of the shelf to the inner box, enables the thinning of these mounting members and suppresses the reduction of volume.

[0006] The refrigerator of the embodiment includes: a refrigerator body, insulated with heat-insulating material in the heat-insulating space between the inner box and the outer box, with the inner side of the inner box serving as the internal space; a shelf disposed in the internal space; and a support mechanism for supporting the shelf in the internal space.

[0007] The support mechanism includes: a support member having a mounting portion for placing the shelf; and a pair of mounting members for mounting the support member to the inner box, which are composed of an inner box mounting member and an outer box mounting member. The inner box mounting member is disposed on the inner box space side and is capable of holding the support member. The outer box mounting member is disposed on the heat-insulating space side opposite the inner box mounting member through the inner box. The inner box mounting member is provided with an insertion portion into which an insertion portion formed in the support member is inserted. The support member is configured to be mounted to the inner box by being inserted into the insertion portion through the insertion portion, and at least a portion of the insertion portion is located on the heat-insulating space side of the inner box through an opening provided in the inner box.

Detailed Implementation

[0039] Hereinafter, refrigerators according to several embodiments will be described with reference to the accompanying drawings. Furthermore, in each embodiment, substantially identical components are labeled with the same reference numerals, and descriptions are omitted.

[0040] <First Implementation Method>

[0041] Figure 1 The refrigerator 1 shown is mainly composed of a long, rectangular, box-shaped, insulated box 2 with an opening on the front surface. The insulated box 2 is the main body of the refrigerator, containing multiple storage compartments, and is also referred to below as "refrigerator body 2". Furthermore, in the following description, the opening side of the refrigerator body 2 is referred to as the front side or near the front side, and the left-right direction when viewed from the front of the refrigerator body 2 is referred to as the left-right direction of the refrigerator 1 (see reference). Figure 1 (The direction of the "left" and "right" arrows). Furthermore, in the refrigerator body 2, the direction towards the center inner side of the storage compartment is called the inner side of the compartment, and the direction towards the outer side of the storage compartment is called the outer side of the compartment.

[0042] exist Figure 1 In the refrigerator body 2 shown, a foamed insulation material 3a, such as polyurethane foam, is disposed in the heat-insulating space between the steel outer casing 2b and the synthetic resin inner casing 2a. For ease of explanation, this will only be discussed later. Figure 22 The diagram shows foamed thermal insulation material 3a. In addition to foamed thermal insulation material 3a, vacuum insulation board 3b (see figure) is also included as a thermal insulation material. Figure 22 They can also be used together, as will be discussed later.

[0043] As multiple storage compartments within the refrigerator body 2, i.e., the interior space inside the inner box 2a, for example, starting from the top of the refrigerator body 2, there are, for example, a refrigerator compartment 11 and a vegetable compartment 12, arranged sequentially below them on the left and right sides, an ice-making compartment 13 and a small freezer compartment 14, and a freezer compartment 15 arranged below them. The refrigerator compartment 11 and the vegetable compartment 12 are storage compartments in the refrigeration temperature range, while the ice-making compartment 13, the small freezer compartment 14, and the freezer compartment 15 are storage compartments in the freezing temperature range.

[0044] In addition, hinged double-opening insulated doors 11a and 11b are provided at the front surface opening of the refrigerator compartment 11, and drawer-type insulated doors 12a to 15a are provided at the front surface opening of the other storage compartments 12 to 15.

[0045] like Figures 1-3 As shown, the refrigerator 1 includes, for example, shelves 20 and 23 disposed in the refrigerator compartment 11; and a support mechanism 10 for supporting the shelves 20 and 23 in the refrigerator compartment 11.

[0046] Shelves 20 and 23 are shelves used for holding stored items, such as... Figure 2 , Figure 3 As shown, they are formed into rectangular plates.

[0047] like Figure 3 , Figure 4 As shown, the support mechanism 10 includes: a support member 30 having a mounting portion 31 for mounting shelves 20 and 23; and a pair of mounting members 40 and 50, which are composed of an inner mounting member 40 for mounting the support member 30 to the inner box 2a and an outer mounting member 50. Wherein, as Figures 1-3 As shown, the support member 30 and the inner mounting member 40 are disposed on the inner space side of the box, but the outer mounting member 50 is disposed on the heat-insulating space side outside the inner box 2a (see below). Figure 5 , Figure 6 ).

[0048] In this case, such as Figure 1 As shown, mounting components 40 and 50 are fixed to the left and right walls of the refrigerator compartment 11. Each mounting part in the inner box 2a is referred to as "the part to be installed 5" (see reference). Figure 2 , Figure 6 Furthermore, the support member 30 is configured to be detachable from the mounting member 40, thereby allowing the height position of the support member 30 and even the shelves 20 and 23 relative to the mounting member 40 to be changed. The structure of the shelves 20 and 23 and their support mechanism 10 will be described in detail below. In addition, the shelves 20 and 23 of this embodiment include a non-divided first shelf 20 and a two-divided second shelf 23, and the second shelf 23 is composed of a front member 21 and an inner member 22.

[0049] That is, firstly, shelves 20 and 23 Figure 2 , Figure 3 The first shelf 20 shown at the top has a plate component 20a that forms its main body and a frame component 20b surrounding it. The plate component 20a is formed, for example, from a glass plate, and the frame component 20b is formed, for example, from resin to protect the plate component 20a. When the first shelf 20 is placed on the mounting portion 31 of the support member 30, the frame component 20b becomes the part that contacts the support member 30. Alternatively, the plate component 20a and the frame component 20b may be made of, for example, a single molded article of resin.

[0050] like Figure 2 , Figure 3 As shown, on the first shelf 20, a clamping portion 20d and a first protrusion 20c are provided on the left and right sides of its frame member 20b. Here, Figure 7 (a) and (b) represent longitudinal sections near the clamping portion 20d and the first protrusion 20c on the left side of the first shelf 20.

[0051] Such as Figure 7 As shown in (a) and (b), both the clamping portion 20d and the first protrusion 20c protrude downwards from the lower surface of the first shelf 20. The clamping portion 20d, through the lower surface of the first shelf 20 and the portion protruding from that lower surface in an "L" or "へ" shape, has a longitudinal section resembling the shape of a "コ" (ko), clamping the mounting portion 31 side of the support member 30. Furthermore, the first protrusion 20c is shaped to fit into the recess 32a on the mounting portion 31 side, which will be described later.

[0052] Thus, the first shelf 20 is positioned appropriately within the support member 30 (see reference). Figure 3The upper part of the support member 30 is restricted from moving in the vertical direction by the clamping part 20d and from moving in the depth direction by the first protrusion 20c.

[0053] The clamping part 20d, the first protrusion 20c, and the frame member 20b in the first shelf 20 are integrally formed. Additionally, as... Figure 2 , Figure 3 As shown, the clamping portion 20d is formed at a rearward position of the frame member 20b, and the first protrusion 20c is formed at a forward position of the frame member 20b. Thus, in the first shelf 20, the clamping portion 20d exists on the inner side, which is further rearward than the first protrusion 20c.

[0054] In contrast, Figure 1 , Figure 3 The second shelf 23 shown at the bottom is a two-part structure consisting of a shelf 21 (also called front part 21) disposed on the front side of the support member 30 in the longitudinal direction and a shelf 22 (also called inner part 22) disposed on the inner side of the front part 21. Its width dimension in the left and right direction is the same as the width dimension of the first shelf 20.

[0055] That is, the front component 21 and the inner component 22 are each rectangular plate, and their respective depth dimensions in the front-to-back direction are, for example, set to approximately half or less than half the depth dimension of the first shelf 20. Therefore, when the front component 21 and the inner component 22 are arranged as follows... Figure 3 When the lower part of the support member 30 is arranged in a front-to-back arrangement on the mounting part 31 as shown, the front-to-back dimension of the entire component 21, 22 is equal to or less than the front-to-back dimension of the first shelf 20.

[0056] Although detailed illustrations are omitted, the front component 21 has, for example, a glass plate component and a resin frame component 21b, and the inner component 22 also has, for example, a glass plate component and a resin frame component 22b.

[0057] like Figure 3 As shown in the lower part, in the front part 21, a clamping part 21d is provided at a position in front of the frame part 21b, and a protrusion 21c (also called a second protrusion 21c) is provided at a position further back.

[0058] Similarly, in the inner component 22, a clamping part 22d is provided at a position in front of the frame component 22b, and a protrusion 22c (also called a third protrusion 22c) is provided at a position further back.

[0059] Thus, in the second shelf 23, which is composed of the front part 21 and the inner part 22, and the first shelf 20, which is not a two-part type, the relative positional relationship (front-back direction positional relationship) between the clamping parts 21d, 22d, 20d and the protrusions 21c, 22c, 20c is reversed, but the shapes of each clamping part 21d, 22d, 20d are the same, and the shapes of the protrusions 21c, 22c, 20c are also the same.

[0060] Thus, the shapes of the clamping portions 21d, 22d, and protrusions 21c, 22c in the front component 21 and the inner component 22 are consistent with... Figure 7 The clamping portion 20d and the first protrusion 20c of the first shelf 20 shown in (a) and (b) have the same shape, so their detailed description is omitted.

[0061] The support component 30 is detachably mounted on the left and right inner walls of the refrigerator compartment 11 via the mounting component 40.

[0062] Here, in Figure 3 For ease of explanation, three support components 30 are shown in the diagram. Figure 1 , Figure 2 The number of support members 30 shown in the figure is also different, but each support member 30 is related to... Figure 4 The support component 30 is the same.

[0063] That is, the support component 30 is made of resin material and is formed as a long strip of prism in the depth direction of the cold storage compartment 11.

[0064] In this case, Figure 4 In the support member 30 shown, the mounting portion 31 has a mounting surface 31a for mounting shelves 20 and 23 and a vertical wall surface 31b erected on the side of the shelves 20 and 23, and is in the form of a stepped column (see reference). Figure 7 (a)). Additionally, in the support member 30, Figure 4 The two claw portions 33, 33 and the three recesses 32a, 32b, 32c shown are formed symmetrically with respect to the center line that divides the support member 30 equally in the length direction.

[0065] Therefore, in Figure 1 Multiple support components 30 are installed on the left and right sides inside the refrigerator compartment 11, or as... Figure 3 The multiple support components 30 that are installed vertically are thus standardized.

[0066] In detail, such as Figure 3 , Figure 4 , Figure 7As shown in (a), in the mounting portion 31 of the support member 30, the mounting surface 31a is formed as a flat surface extending in the horizontal direction, and the vertical wall surface 31b is erected along the frame members 20b to 22b of the shelves 20 and 23. Thus, when the shelves 20 and 23 are mounted on the mounting surface 31a, even if they come into contact with the vertical wall surface 31b, they can extend in a manner that does not come into contact with the inner box 2a, which serves as the inner wall surface, on the vertical wall surface 31b.

[0067] In addition, such as Figure 4 As shown, inclined portions 34a and 34b, which are inclined in such a way that the width of the mounting surface 31a narrows as it moves toward the two ends of the support member 30 in the length direction, are symmetrically provided on the mounting portion 31 at both ends of the length direction.

[0068] like Figure 7 As shown in (a), the lower surface of the support member 30 is formed as an inclined surface that slopes downward toward the inner wall surface. In this case, the mounting surface 31a of the support member 30 and the inclined surface become the portions clamped by the clamping portions 20d to 22d of the shelves 20 and 23. Therefore, in the longitudinal section of this figure, the U-shape of the clamping portion 20d becomes a shape that slightly expands to match the inclined surface on the inner wall surface side.

[0069] like Figure 4 As shown, the support member 30 is provided with three recesses 32a, 32b, and 32c that cause the mounting surface 31a to be recessed downwards. The recesses 32a, 32b, and 32c are formed at positions corresponding to the protrusions 20c, 21c, and 22c of each shelf 20 and 23.

[0070] That is, the recessed portion 32a is in Figure 4 A recessed portion (also called end-side recessed portion 32a) is provided at the rearmost position of the inclined portion 34a shown on the mid-forward side, that is, at the end of the support member 30 near the front side in the longitudinal direction. For example... Figure 3 As shown above, the end-side recess 32a can restrict the movement of the shelf 20 in the depth direction by allowing the first protrusion 20c of the first shelf 20 to be inserted.

[0071] The recess 32b is a recess located at the center of the support member 30 in the longitudinal direction (also called a central side recess 32b). Figure 3 As shown in the lower part, the central recess 32b is able to restrict the movement of the front component 21 in the depth direction by being inserted into the second protrusion 21c of the front component 21.

[0072] The recessed portion 32c is provided in Figure 4 The recessed portion (also called end-side recessed portion 32c) located near the front of the inclined portion 34b shown on the inner side of the support member 30, i.e., at the end of the support member 30 along its length direction. Figure 3 As shown in the lower part, the end side recess 32c is inserted into the third protrusion 22c of the inner side member 22, thereby restricting the movement of the inner side member 22 in the depth direction.

[0073] Furthermore, the central recess 32b in the support member 30 is wider in the longitudinal direction compared to the other recesses 32a and 32c, but it is sufficient as long as it is formed at the position corresponding to the second protrusion 21c. That is, as long as the second protrusion 21c is provided on either the front member 21 or the inner member 22, and the third protrusion 22c is provided on the other, the second protrusion 21c is embedded in the central recess 32b, and the third protrusion 22c is embedded in the end recess 32a or 32c, thereby enabling the same support member 30 to support both the front member 21 and the inner member 22.

[0074] In addition, such as Figure 4 , Figure 7 As shown in (b), each recess 32a to 32c is open to the upper side and the inner side of the box. Furthermore, with shelves 20 and 23 placed on the mounting surface 31a, the bottom surface of recesses 32a to 32c is set to a depth that does not contact the lower ends of the corresponding protrusions 20c to 22c (see reference). Figure 7 (b)

[0075] In this way, the support member 30 is configured such that the recessed portions 32a to 32c are arranged to be used not only for the non-divided first shelf 20, but also for the front part 21 and the inner part 22 of the second shelf 23.

[0076] like Figure 4 As shown, the two claw portions 33, 33 are integrally formed insertion portions at locations separated along the length of the support member 30. Also as... Figure 7 As shown in (a), the claw portion 33 is formed to protrude from the support member 30 toward the inner wall surface, which is the inner box 2a side, and the front end portion of the claw portion 33 is bent at approximately a right angle toward the upper side. In this case, the outer peripheral surface of the claw portion 33 is formed as a curved surface that is bent into an arc shape.

[0077] Thus, the support member 30 is installed by inserting and hooking its two claws 33, 33 into and onto the insertion portions 41, 41 of the mounting members 40, 40 (see reference). Figure 7 (a)

[0078] Here, focusing on Figure 7 The method of mounting and dismounting the support member 30 is briefly described using a claw portion 33 and an insertion portion 41 of the mounting member 40 shown in (a).

[0079] First, when removing the support component 30 from the mounting component 40, the user should pre-install... Figure 7 Shelf 20 of (a) is removed. Additionally, in this case, as... Figure 7 As shown in (a), the support member 30 is in a locked state where the claw 33 is inserted into the inserted part 41, and the side of the support member 30 is in contact with the surface of the mounting member 40 and is held in a mounting position.

[0080] Here, the user, for example, holds the support member 30 near the recess 32b, so that... Figure 7 Using the claw portion 33 as a fulcrum, the entire support member 30 is rotated in the upward disassembly direction. Simultaneously, by rotating the claw portion 33 to a disassembly position where it is pulled out from the insertion portion 41, the locking state of the claw portion 33 can be released, thereby disassembling the support member 30.

[0081] In contrast, when installing the support member 30 onto the mounting member 40, the user positions the support member 30 in the aforementioned removed position, with the front end of the claw 33 facing the insertion portion 41, for alignment. This alignment is performed near the inner wall of the inner casing 2a, but it can be done relatively easily by holding the recessed portion 32b of the support member 30 or the stepped portion of the mounting portion 31. With the support member 30 aligned in this manner, it is rotated downwards in the mounting direction, using the claw 33 side as a fulcrum. Accompanying this, as... Figure 7 As shown in (a), the claw 33 is inserted into the inserted portion 41 and rotated to the mounting position, thereby enabling the support member 30 to be mounted.

[0082] Furthermore, mounting components 40 and 50 are respectively located at Figure 1 The left and right inner walls of the refrigerator compartment 11 shown are equipped with support members 30 at two locations separated along the depth direction.

[0083] Here, Figure 2 This is a perspective view of the structure on the left side of the refrigerator compartment 11 as seen from the inside of the box, that is, a perspective view showing the box-side mounting components 40, 40 on the left wall of the inner box 2a. Figure 6 This is a side view of the mounted portions 5, 5 on the left wall of the inner box 2a, viewed from the outside of the box; that is, a side view showing the outer mounting components 50 of the two mounted portions 5, 5. Furthermore, in this… Figure 6 In the diagram, the right-hand (near the front) mounting portion 5 represents the assembled state of the outer mounting component 50 and the inner mounting component 40, while the left-hand (inner) mounting portion 5 represents the state before these mounting components 40 and 50 are assembled. Additionally, Figure 5 This is an exploded perspective view of the inner mounting component 40 and the outer mounting component 50 of the box, viewed from the inside of the box.

[0084] like Figures 1-3 , Figure 6As shown, the mounting portions 5 of the mounting components 40 and 50 in the inner box 2a are located at various locations separated in the front-rear direction, and are referred to as being near the openings 6 formed on the left and right walls. The mounting components 40 and 50 are positioned opposite each other across the mounting portions 5 of the inner box 2a.

[0085] That is, such as Figure 6 As shown, multiple openings 6 are formed in a rectangular shape with cuts extending longitudinally along the length of the mounting components 40 and 50. In this case, for example, three openings 6 are provided with two bridging portions 5a that divide them vertically, thereby creating a configuration that suppresses deformation around the mounted portion 5 in the inner casing 2a. In addition, the width of the openings 6 is set to be smaller than the width of any of the mounting components 40 and 50.

[0086] Additionally, in the inner box 2a, the hole for the screw 7 shown above the opening 6 is positioned relative to the opening 6 in the front-back direction ( Figure 6 The holes are offset in the left-right direction. This is to prevent incorrect assembly of the mounting components (40° and 50°) by mirroring each other, which would cause the holes to be misaligned. Details will be explained later.

[0087] An installation component 40 is provided inside the mounting portion 5 of the inner casing 2a.

[0088] The inner mounting component 40 of the box is, for example, made of a flexible synthetic resin material, such as... Figure 5 As shown, the main body is a thin plate-shaped surface 40a with relatively low thickness (see reference). Figure 10 (a) is a long strip that is relatively long in the vertical direction.

[0089] The inserted part 41 has, for example, seven parts arranged at approximately equal intervals along the length direction (vertical direction) of the mounting component 40 inside the box. Additionally, as... Figure 8 of (a), Figure 7 As shown in (a), the inserted portion 41 penetrates the main face 40a and extends from the main face 40a toward the outer side of the box, which is the outer side. In this case, the inserted portion 41... Figure 7 In the longitudinal section of (a), it is an arc shape that matches the shape of the claw 33, and extends through the opening 6 of the inner box 2a to the clearance recess 51 of the mounting component 50 on the outside of the box.

[0090] With the shape of the inserted part 41, the mounting member 40 can stably hold the claw part 33 and even the support member 30. In addition, combined with the structure of the main face 40a which is in the shape of a thin plate, at least a portion of the claw part 33 is located outside the inner box 2a through the opening 6.

[0091] On the inner side mounting component 40, engaging recesses 42 and 43 are formed on the outer side of the main face 40a (see reference). Figure 8of (a), Figure 10 (a) and (b)). On the other hand, on the outer mounting member 50, on the inner side of the main face 50a, there are engaging protrusions 52 and 53 corresponding to engaging recesses 42 and 43 (see reference). Figure 5 , Figure 8 (b) Figure 10 (a) and (b)).

[0092] In this embodiment, in the mounting components 40 and 50, the convex or concave parts that can engage with each other are referred to as "engaging convex parts" or "engaging concave parts", the latter of which includes "hole" shapes.

[0093] Thus, the mounting components 40 and 50 of this embodiment adopt a structure in which the two mounting components 40 and 50 are combined by engaging with each other through the opening 6 by a engaging protrusion formed on at least one of them and an engaging recess formed on the other. Details of these engaging protrusions and engaging recesses will be described later.

[0094] Furthermore, in this embodiment, the mounting components 40 and 50 on the inner and outer sides of the box are of two types: a left-side mounting component disposed on the left side wall of the inner box 2a, and a right-side mounting component disposed on the right side wall. Figures 5-10 In the diagram, the mounting components 40 and 50 on the left are indicated.

[0095] Regarding this, relative to the mounting components 40 and 50 of the left-hand specification, the mounting components of the right-hand specification are centered on the axis 400 and 500 in the width direction (see reference). Figure 5 , Figure 8 The shape is the result of reversing the axis of symmetry. Therefore, regarding the mounting components 40 and 50, the mounting component of the left side and the mounting component of the right side are respectively matched with the left and right side walls (corresponding mounting parts 5) of the inner box 2a, thus forming a configuration that is symmetrical with respect to the inner box 2a.

[0096] Therefore, for example, the sliding direction of the outer mounting component 50 of the box, described later, is independent of the left and right side specifications, and becomes a direction from the near front side toward the inward side (see reference). Figure 6 (The arrows pointing in the forward and backward directions). Therefore, for ease of explanation, the mounting components 40 and 50 in this embodiment will be referred to by the same symbols "40" and "50" regardless of the specifications of the left and right sides.

[0097] On the mounting components 40 and 50 of the left-side specification, on the outer surface of their respective housings, there is an additional mark indicating the left-side specification or the letter "L" as the identifier M1. Figure 6Only the marking M1 of mounting component 50 is shown in the diagram. Furthermore, although the diagram is omitted, the aforementioned suppression of misassembly is achieved by marking the mounting components 40 and 50 on the right side with the letter "R" as the marking for the right-side specification. Additionally, regarding the right-side specification, in other embodiments... Figure 12 , Figure 17 Further explanation will be provided in the following section.

[0098] like Figure 8 As shown, a boss 45 is provided at the rear of the upper end of the mounting component 40 inside the box. The front end of the boss 45 is larger than the hole for the screw 7 in the inner box 2a (strictly speaking...). Figure 7 The hole for the boss portion 45 shown protrudes further outward from the box. The two mounting components 40 and 50 are fixed to the inner box 2a by screwing the screw 7 into the boss portion 45 from the side of the mounting component 50 on the outside of the box. Furthermore, the boss portion 45 in the mounting component 40 on the inside of the box is located further rearward (…). Figure 8 (Middle left) can prevent misassembly.

[0099] like Figure 5 As shown, a downwardly extending flange 46 is provided at the lower end of the mounting component 40 inside the box. The flange 46 is inserted into the box from the lowermost edge of the opening 6 towards the outside (see below). Figure 11 (a)

[0100] Thus, the inner mounting component 40 is configured such that its main face 40a protrudes into the inner side of the box when it is embedded in the opening 6.

[0101] The external mounting component 50 of the enclosure is, for example, made of a flexible synthetic resin material, such as... Figure 5 As shown, the main body is a rectangular thin plate-shaped surface 50a with relatively small thickness (see reference). Figure 10 (a) is a long strip that is relatively long in the vertical direction.

[0102] In addition, such as Figure 5 , Figure 10 As shown in (a), the main face 50a of the outer mounting component 50 is wider than the main face 40a of the inner mounting component 40.

[0103] like Figure 5 As shown, the outer mounting component 50 of the box is provided with, for example, seven clearance recesses 51, the number and arrangement of which correspond to the seven insertion portions 41 of the inner mounting component 40 of the box.

[0104] The clearance recess 51 is a shallow, rectangular recess with an opening on all six sides. For example... Figure 7As shown in (a), the clearance recess 51 is formed such that both the claw portion 33 and the inserted portion 41 can enter, covering the inserted portion 41 from the heat insulation space side. The clearance recess 51 only needs to be formed such that at least one of the claw portion 33 and the inserted portion 41 can enter.

[0105] like Figure 7 , Figure 9 of (a), Figure 10 As shown in (a), the clearance recess 51 is formed such that the main surface 50a is recessed towards the heat insulation space side. Therefore, the outer wall portion of the clearance recess 51 on the heat insulation space side corresponds to the recess and becomes the outer side protrusion 51a of the box that protrudes towards the heat insulation space side from the main surface 50a. In addition, the outer side protrusion 51a is set to be larger than the main surface 50a. Figure 7 The head of screw 7 shown in (b) protrudes slightly (by a factor of ΔL) toward the insulation space by a certain length.

[0106] In addition, Figure 7 In the sectional view, to make it easier to understand the structure of each component, some section lines are omitted, or a part of the structure is simplified and schematically shown.

[0107] Furthermore, the outer mounting member 50 is positioned relative to the inner mounting member 40 embedded in the opening 6, along the wall of the mounted portion 5, for example from the front side to the inside (see reference). Figure 6 The components slide in a manner indicated by the arrows pointing forward and backward. At this time, the outer mounting component 50 engages with its engaging protrusions 52 and 53, which in turn engage with the engaging recesses 42 and 43 of the inner mounting component 40, and from... Figure 6 The main face 50a, as shown in the figure, is slid to its fixed position when viewed from the side of the insulated space.

[0108] In this state, the outer mounting component 50 is screwed into the boss portion 45 of the inner mounting component 40 through the screw 7 from its outer side (see reference). Figure 7 (a) is thus fixed to the inner box 2a together with the inner mounting part 40. In this way, screws 7 are used as fixing parts for fixing the outer mounting part 50 relative to the inner mounting part 40.

[0109] Here, Figure 10 (a), (b), (c), and (d) indicate along Figure 6 The cross-sectional views are shown along lines Xa-Xa, Xb-Xb, Xc-Xc, and Xd-Xd. The following is a detailed description of the engaging recesses 42 and 43 and engaging protrusions 52 and 53 and their surrounding structures in each mounting component 40 and 50.

[0110] Figure 10 (a) indicates along Figure 6The cross-section of the engaging recess 42 of the inner mounting component 40 of the Xa-Xa line and the engaging protrusion 52 of the outer mounting component 50.

[0111] like Figure 10 of (a), Figure 8 As shown in (a), the engaging recess 42 has its base end at the front end of the main surface 40a in the width direction, and its front end is a protrusion extending to the heat-insulating space side of another main surface 50a, which extends in a manner that engages with the engaging protrusion 52. The engaging recess 42 is formed with a concave shape having a hole 42a that passes through in the front-back direction, which is the sliding direction, as shown in (a). Figure 8 As shown in (a), it is a slightly elongated rectangular frame as a whole.

[0112] In this case, the hole 42a is a through-hole, not a non-through-hole. Additionally, as... Figure 9 of (a), Figure 10 As shown in (a), the engaging recess 42 is configured to be surrounded or sandwiched by the outer side protrusion 51a of the casing, and its protrusion length is set to not extend from the outer side protrusion 51a towards the heat insulation space side. In this case, the protrusion length of the engaging recess 42 may also be set to be smaller than the protrusion length of the outer side protrusion 51a of the casing.

[0113] like Figure 8 (b) Figure 10 As shown in (a), the engaging protrusion 52 is composed of a tongue portion 52a, which is located near the opening 52b formed on the main face 50a by cutting off the half of the width direction near the front side corresponding to the engaging recess 42, and extends inward (rearward) with the edge of the working side of the opening 52b as the base end.

[0114] Therefore, with the opening 52b surrounding the engaging recess 42 receiving the tongue portion 52a of the engaging protrusion 52, the tongue portion 52a moves in the sliding direction by inserting itself into the hole 42a of the engaging recess 42, thereby engaging with the engaging recess 42. Furthermore, in this case, as... Figure 9 As shown in (a), when viewing the outer mounting component 50 from the outside of the box, the engaging recess 42 can be seen from the opening 52b around the engaging protrusion 52.

[0115] The above Figure 10 The engagement recess 42 and engagement protrusion 52 of (a) are paired as follows Figure 6 The symbols "42, 52" or Figure 5 As indicated by the symbol "52", four pairs of mounting components 40 and 50 are arranged at approximately equal intervals in the vertical direction. Furthermore, as described above, a portion of the claw 33 enters... Figure 5The avoidance recess 51, therefore the engaging recess 42 and engaging protrusion 52 are disposed between the vertically arranged avoidance recesses 51, or separated from the avoidance recesses 51 in the vertical direction.

[0116] Figure 10 (b) indicates along Figure 6 The cross-section of the engaging recess 43 of the inner mounting component 40 and the engaging protrusion 53 of the outer mounting component 50 of the Xb-Xb line.

[0117] like Figure 10 (b) Figure 8 As shown in (b), the engaging protrusion 53 is located near the opening 53b formed by cutting off the central portion of the main face 50a in the width direction, and is composed of a tongue portion 53a with the working edge of the opening 53b as its base. The tongue portion 53a extends from its base toward the other side of the main face 40a (the box space side) and engages with the engaging recess 43, and is formed in an L-shape that curves inward along the main face 40a.

[0118] like Figure 8 of (a), Figure 10 As shown in (b), the engaging recess 43 is a concave-shaped portion recessed in the width direction of the main face 40a, and is composed of a receiving portion 43a. The receiving portion 43a uses a tongue portion 43b formed by folding back from the inside of the main face 40a to the front side to receive and engage the other tongue portion 53a.

[0119] Therefore, with the tongue portion 53a of the engaging protrusion 53 housed in the concave space, the engaging recess 43 moves in the engaging direction, which is the sliding direction, in a manner that allows it to be inserted into the housing portion 43a, thereby engaging with the engaging protrusion 53.

[0120] Should Figure 10 (b) The engaging recess 43 and engaging protrusion 53 are paired as follows Figure 6 The symbols "43, 53" or Figure 5 As indicated by the symbol "53", a pair is provided between multiple clearance recesses 51 in the vertical direction of the mounting components 40 and 50. Alternatively, with... Figure 6 Similarly, multiple pairs of engaging recesses 42 and engaging protrusions 52 can also be provided.

[0121] As described above, the engaging protrusions 52 and 53 of this embodiment have tongue portions 52a and 53a that extend in the engaging direction along the wall of the inner box 2a, and engaging recesses 42 and 43 have holes 42a or receiving portions 43a that are formed so that the engaging protrusions 52 and 53 can be inserted in the engaging direction, but are not limited thereto (described in other embodiments).

[0122] In addition, at least one of the mounting components 40 and 50 in this embodiment has an anti-detachment portion that protrudes toward another mounting component in a direction perpendicular to the engagement direction.

[0123] For example, Figure 10 (d) indicates along Figure 6 The cross-section of the anti-detachment part 54a of the outer side mounting component 50 of the Xd-Xd line box and the inclined protrusion 44a of the inner side mounting component 40 of the box.

[0124] Figure 10 The inclined protrusion 44a shown in (d) is the flange 46 formed at the lower end of the main face 40a (see reference). Figure 5 The anti-detachment portion is integrally formed at the center of the outer side surface of the box in the width direction. The inclined protrusion 44a is located in this... Figure 10 The cross section of (d) is triangular, and has a gently sloping surface that protrudes from its front side toward the inside to the other side of the main face 50a and a step that locks the anti-detachment part 54a of the other side of the main face 50a.

[0125] Such as Figure 10 (d) Figure 5 As shown, the anti-detachment part 54a is a protrusion integrally formed with a concave part 54 that slightly recesses the inner side of the main face 50a, similar to the avoidance recess 51. It protrudes into the inner side of the box, perpendicular to the engagement direction, from the center of the main face 50a in the width direction.

[0126] When mounting components 40 and 50 are assembled, one mounting component 50 is positioned near the front in the sliding direction such that an inclined protrusion 44a is received in its concave portion 54. Furthermore, as the mounting component 50 moves in the sliding direction, the anti-detachment portion 54a rises along the inclined protrusion 44a, reaching the aforementioned fixed position (as described above). Figure 10 The moment when the position (d) is crossed is stopped by the step of the inclined protrusion 44a, giving a sense of rhythm (or making a sound when stopped).

[0127] In this way, the inclined protrusion 44a of the other mounting component 40 prevents the anti-detachment part 54a from falling off in the sliding direction near the front, i.e., in the opposite direction of the engagement direction, thereby maintaining the assembled state of the mounting components 40 and 50. When the mounting component 50 slides, the other temporarily engaged engagement recesses 42 and 43 and engagement protrusions 52 and 53 (refer to the above) can be engaged. Figure 10 (a) and (b) do not detach. In addition, by sliding the mounting part 50 to a fixed position that provides a sense of rhythm, the anti-detachment part 54a can be reliably prevented from falling off by using the inclined protrusion 44a.

[0128] As described above, the engaging recesses 42 and 43 and the engaging protrusions 52 and 53 are arranged in a configuration that extends along the length of the mounting members 40 and 50 and alternates with the insertion portion 41 of the claw portion 33 (see reference). Figure 5 Therefore, a robust assembly of the two mounting components 40 and 50 can be achieved. In addition, the assembly operation using sliding movement can be simplified and the assembly accuracy improved. Moreover, even if the mounting components 40 and 50 are relatively thin components, they can be combined with the reinforcing ribs and other structures described later to reinforce each other.

[0129] also, Figure 10 (c) indicates a cross-section of the inserted portion 41 and the clearance recess 51 in the mounting components 40 and 50, for example, provided on the mounting component 40 inside the box. Figure 10 The positioning part St1 of (c) will be described in detail in the second embodiment (see reference). Figure 11 (b) of St1′).

[0130] Furthermore, the openings 52b and 53b of the aforementioned outer casing mounting component 50 are connecting holes that allow the designated space between the mounting component 50 and the inner casing mounting component 40 to communicate with the insulation space (see reference). Figure 10 (a) and (b)), the specified space is surrounded by a first blocking portion protruding from at least one direction of these mounting components 40 and 50 to the other.

[0131] The first blocking portions 481 and 482 in this embodiment include, for example, […]. Figure 10 As shown in (a) and (b), the longitudinal ribs 48a to 48d formed on the inner side of the mounting component 40 of the box, the Figure 10 The openings 52b and 53b of the outer mounting component 50 of (a) and (b) serve as connecting holes (see reference). Figure 8 (b)) becomes a structure in which the foamed insulation material 3a is blocked from entering the inside of the box from the opening 6 of the specified spaces S1, S2 or the inner box 2a.

[0132] Here, Figure 9(b) and (d) illustrate the similarities with Figure 10 The first blocking portions 481 and 482 of the mounting component 40 corresponding to the specified spaces S1 in (a) and S2 in (b) are explanatory diagrams showing the openings 52b and 53b of the other mounting component 50 as viewed from the heat-insulating space side, indicated by double-dotted lines.

[0133] Right now, Figure 10 The longitudinal ribs 48a and 48b of the first blocking portion 481 shown in (a) are located at both ends of the main face 40a in the width direction opposite to the opening 52b of the outer mounting member 50 of the box, and extend in the vertical direction along the edge of the opening 6 of the inner box 2a (see reference). Figure 9 (b) of. For example Figure 10 As shown in (a), the longitudinal ribs 48a and 48b protrude in the thickness direction of the inner box 2a, and their front ends are formed in a manner that engages with the opposite main face 50a.

[0134] In addition, such as Figure 8 As shown in (a), on the outer side of the housing where the inner housing mounting component 40 is installed, there are a plurality of reinforcing ribs (hereinafter referred to as "horizontal ribs 48r") that divide the respective portions of the insertion portion 41, the engaging recess 42, and the engaging recess 43 vertically. The horizontal ribs 48r protrude in such a way that their front ends engage with the opposing main face portion 50a.

[0135] thus, Figure 10 The first blocking part 481 of (a) is framed by longitudinal ribs 48a and 48b fitted into the edge of the opening 6 of the inner box 2a and transverse ribs 48r and 48r on its upper and lower sides (see reference). Figure 9 The square with dashed lines shown by symbol 481 in (b) and Figure 8 (a) and has a structure blocked by the joint portion of the two mounting parts 40 and 50.

[0136] like Figure 10 As shown in (a), the longitudinal rib 48b becomes the joint portion that engages with the tongue portion 52a, and the joint surface is wider than that of the longitudinal rib 48a. A soft strip 8 can also be attached to the joint surface between the longitudinal rib 48b and the tongue portion 52a as a sealing surface.

[0137] so, Figure 9 of (a), Figure 10 The specified space S1 shown in (a) is surrounded by a frame-shaped first blocking portion 481 protruding from one mounting member 40 to another mounting member 50 (see reference). Figure 9 (b) A soft strip 8 is used on the mating surfaces of the mounting components 40 and 50.

[0138] Although a detailed illustration of the softband 8 is omitted, it can be seen, for example, as shown below. Figure 10As shown in (c), a gap G is provided on the inner side of the outer periphery of the outer mounting component 50 of the box to serve as the adhesive allowance for the soft strip 8, and the outer periphery of the outer mounting component 50 of the box also serves as a sealing surface.

[0139] Figure 10 The first blocking part 482 of (b) is also composed of... Figure 10 The longitudinal ribs 48a and 48b of (a) and the same longitudinal ribs 48c and 48d, along with the transverse ribs 48r and 48r, form a frame (see reference). Figure 9 The square with dashed lines shown by the symbol (d) 482 and Figure 8 (a) has a structure that serves as a barrier as the joint of the two mounting components 40 and 50.

[0140] Figure 9 (c) is along Figure 9 The perspective view near the first blocking portion 482, shown by sectioning along line IXc-IXc (d), is illustrated by double-dotted lines indicating the outer mounting component 50 of the housing, and the opening 53b, serving as a connecting hole, is simplified. Figure 9 As shown in (c), the defined space S2 between the two mounting members 40 and 50 is surrounded by a first blocking portion 482 protruding from one mounting member 40 to the other mounting member 50. Additionally, as shown in... Figure 9 The symbol 8 (c) can also be found in the tongue portion 43b (or Figure 10 A soft strip 8 is pasted onto the mating surfaces of the two mounting parts 40 and 50 near the tongue portion 53a) of (b) as a sealing surface.

[0141] Furthermore, in addition to the first blocking portions 481 and 482 described above, at least one of the mounting components 40 and 50 is provided with a second blocking portion 483 that engages with the inner box 2a on the outer periphery of the opening 6 of the inner box 2a.

[0142] For example, such as Figure 8 of (a), Figure 9 (b), (d) Figure 10 As shown in (c), the second blocking portion 483 is formed by the stepped edge portion 40e of the main face portion 40a at both ends in the width direction (on the sides of the longitudinal ribs 48a to 48d), which overlaps and joins with the periphery of the opening 6. Figure 12 The details of the second blocking part 483 are explained below.

[0143] As described above, the support mechanism 10 of this first embodiment is configured such that the inner side mounting member 40 is provided with an insertion portion 41 into which an insertion portion (e.g., claw portion 33) formed on the support member 30 is inserted, and the support member 30 is mounted on the inner box 2a by inserting the insertion portion into the insertion portion 41, and at least a portion of the insertion portion is located on the heat insulation space side of the inner box 2a through the opening 6 provided in the inner box 2a.

[0144] Therefore, the internal space into which the insertion part, such as the claw part 33, in the inner mounting component 40 is inserted can be expanded through the opening 6 to the heat insulation space side of the inner box 2a, thereby reducing the thickness of the inner mounting component 40 and thus reducing the thickness of the two mounting components 40 and 50.

[0145] The mounting component 50 on the outer side of the box is provided with a clearance recess 51 into which at least one of the insertion part and the inserted part 41 can enter. The clearance recess 51 is configured to be open on the opening 6 side and cover the inserted part 41 from the heat insulation space side (see reference). Figure 7 (a)

[0146] Therefore, even if the recess 51 is provided in the outer mounting component 50 of the box as an insertion part or a space for an insertion part 41 such as a claw part 33, it can be provided in a closed form such that the foamed insulation material 3a will not flow into the space from the outside of the box.

[0147] For example, a vacuum insulation panel 3b (see reference) is disposed in the insulation space. Figure 22 As a vacuum insulation material, the mounting component 50 on the outside of the enclosure uses a fixing component for securing the vacuum insulation panel 3b. In this case, the mounting component 50 on the outside of the enclosure is at least one external protrusion 51a, having an external protrusion 51a, which, for example, is larger than... Figure 7 The part of the fixing component, such as screw 7 in (b), closest to the vacuum insulation material (e.g., the screw head), protrudes into the vicinity of the vacuum insulation material. Alternatively, it can be configured such that, in the outer mounting component 50, an outer protrusion 51a″ other than the outer protrusion 51a is provided (see below). Figure 22 Peripheral rib 51a″, Figure 7 (b) double-dotted lines), using the outer protrusions 51a, 51a″ of these boxes to surround or clamp the fixing parts.

[0148] According to this structure, even when using a fixing component such as screw 7 on the side of the insulated space, the distance from the vacuum insulation material can be ensured by the protrusions 51a and 51a″ on the outside of the box, thus suppressing the risk of damage to the vacuum insulation material.

[0149] At least one of the inner mounting component 40 and the outer mounting component 50 is provided with a locking recess 42, 43, and the other is provided with a locking protrusion 52, 53 that can engage with the locking recess 42, 43. The two mounting components 40, 50 are combined with each other by engaging with the locking recess 42, 43 and the locking protrusion 52, 53.

[0150] The engaging recess 42 is integrally formed with the outer side mounting component 50 or the inner side mounting component 40 of the box, and extends from one side of the inner box 2a’s heat insulation space side and the inner box space side to the other side and engages with the engaging protrusion 52 on the other side.

[0151] Thus, for example, Figure 10 The engaging recess 42 of (a) protrudes from the inner space side to the insulation space side, and even when it reaches the insulation space side of the inner box 2a, it can engage with the engaging protrusion 52 of the outer mounting member 50 without increasing the thickness of the inner mounting member 40 (e.g., the main face 40a).

[0152] The engaging protrusion 53 is integrally formed with the outer side mounting component 50 or the inner side mounting component 40 of the box, and extends from one side of the inner box 2a’s heat insulation space side and the inner box space side to the other side and engages with the engaging recess 43 on the other side.

[0153] Therefore, for example Figure 10 The engaging protrusion 53 of (b) protrudes from the insulation space side to the inner space side, and even when it reaches the inner space side of the inner box 2a, it can engage with the engaging recess 43 of the inner mounting member 40 without increasing the thickness of the mounting member 50 (e.g., the main face 50a) on the outer side of the box. With such a structure of engaging recesses 42, 43 and engaging protrusions 52, 53, it is generally possible to achieve a thinner profile for the two mounting members 40, 50, and to suppress the reduction of the volume inside the box or the volume of the insulation material side outside the box.

[0154] The engaging protrusions 52 and 53 are formed to extend in the engaging direction (e.g., the inner side of the sliding direction) along the wall of the inner box 2a, and the engaging recesses 42 and 43 are formed to be able to be inserted into the engaging protrusions 52 and 53 along the engaging direction.

[0155] Therefore, the engaging protrusions 52 and 53 and the engaging recesses 42 and 43 can be shaped to fit along the wall of the inner casing 2a, thus achieving a thinner profile. Furthermore, the engaging protrusions 52 and 53 and the engaging recesses 42 and 43 can be moved relative to each other along the wall of the inner casing 2a to engage, simplifying the assembly process of the mounting components 40 and 50. Additionally, as described in the above embodiment, since multiple engaging protrusions and engaging recesses are provided along the length of the mounting components 40 and 50, they can be engaged in one go through the sliding (relative movement in the engaging direction), resulting in a secure assembly.

[0156] At least one of the mounting components 40 and 50 (e.g.) Figure 10 The outer mounting member 50 of (d) has an anti-detachment portion 54a that protrudes to the other side in a direction perpendicular to the engagement direction (e.g., the inner space side of the case). The anti-detachment portion 54a is integrally formed on one of the mounting members 50 and is prevented from detaching in the opposite direction of the engagement direction (e.g., the side opposite to the sliding direction) by the other mounting member 40.

[0157] Thus, as the engaging protrusions 52 and 53 and the engaging recesses 42 and 43 engage with each other, the engaging state is maintained by the anti-disengagement part 54a, thereby maintaining the state in which the two mounting parts 40 and 50 are combined with each other.

[0158] The outer mounting component 50 of the enclosure is provided with a communication hole (e.g., to communicate with the heat insulation space through the predetermined spaces S1, S2 between it and the inner mounting component 40 of the enclosure). Figure 8 The openings 52b and 53b of (b) define spaces S1 and S2 as being surrounded by first blocking portions 481 and 482 that protrude from at least one of the mounting components 40 and 50 in the other direction.

[0159] Therefore, even if the foamed insulation material 3a flows in from the openings 52b and 53b of the mounting component 50 on the outside of the box, it can be blocked by the first blocking parts 481 and 482 (see reference). Figure 9 (b) and (d) block the foamed insulation material 3a so that it does not flow into the box from the specified spaces S1 and S2.

[0160] In addition, at least one of the mounting components 40 and 50 is provided with a second blocking portion 483 that overlaps with the inner box 2a on the outer periphery side of the opening 6 of the inner box 2a.

[0161] Therefore, even if there is an opening 6 in the inner box 2a, it can be shaped to block its outer periphery using the second blocking part 483. For example, even if the foamed insulation material 3a flows in from the openings 52b and 53b of the mounting component 50 on the outside of the box, the second blocking part 483 can block the foamed insulation material 3a from flowing into the inner space of the box. Therefore, when the first blocking parts 481 and 482 are provided together with the second blocking part 483, a double blocking part structure can be adopted.

[0162] The blocking portion is not limited to the structure of the blocking portions 481 to 483 described above. As described in other embodiments, a sealing surface may also be provided at the joint portion other than the joint portion. For example, the joint portion at the front end of the transverse rib 48r constituting the first blocking portions 481 and 482 (which joins with the main face 50a) may be used. Figure 9 The front end portion of the transverse ribs 48r (b) to (d) may serve as a sealing surface and may also include an adhesive soft strip 8. Additionally, as... Figure 10 As shown in (a), it can also be configured such that the partition wall 58 (shown only) that separates the opening 52b in the main face 50a is provided in a way that it joins with the main face 40a inside the box, so that it is blocked by the joint of the two 58, 40a.

[0163] A first protrusion 20c is provided on the first shelf 20. This first protrusion 20c can restrict the movement of the shelf 20 in the depth direction (e.g., the front-to-back direction) by embedding into the end-side recesses 32a and 32c of the support member 30. A second protrusion 21c is provided on the front side member 21 or the inner side member 22 constituting the second shelf 23. This second protrusion 21c can restrict the movement of the front side member 21 or the inner side member 22 in the depth direction by embedding into the central side recess 32b of the support member 30 (see reference). Figure 3 ).

[0164] Therefore, in the support member 30, by housing the first protrusion 20c of the first shelf 20 and the second protrusion 21c of the front member 21 or the inner member 22 in the corresponding recesses 32a to 32c, the movement of each shelf 20 and 23 in the depth direction can be restricted within the box space without the protrusions 20c and 21c protruding. In this case, even when the second shelf 23 is composed of the front member 21 and the inner member 22, the movement of the member 21 or 22 can be at least restricted by embedding the second protrusion 21c of one member 21 or 22 into the central recess 32b. Therefore, the first shelf 20 and the second shelf 23 can be used as a support member 30 that can be used together.

[0165] A second protrusion 21c is provided on one of the aforementioned front component 21 and inner component 22, and a third protrusion 22c is provided on the other. The second protrusion 21c is embedded in the central recess 32b, and the third protrusion 22c is embedded in the end recess 32a or 32c, thus enabling both the front component 21 and the inner component 22 to be supported by the same support member 30.

[0166] Therefore, for both the front component 21 and the inner component 22, the movement in the depth direction can be restricted by the support component 30, and appropriate support can be provided. In addition, the same support component 30 can be used to achieve the commonality of components.

[0167] In the support member 30, the mounting part 31 has a mounting surface 31a for mounting the shelves 20 and 23 and a vertical wall surface 31b erected on the side of the shelves 20 and 23, and is stepped.

[0168] Therefore, when placing or removing shelves 20 and 23 from the mounting surface 31a, the vertical wall surface 31b can be used for protection, preventing the sides of shelves 20 and 23 from contacting the inner box 2a. Additionally, for example... Figure 7 As shown in (b), by making the thickness of the shelves 20 and 23 consistent with the height of the vertical wall 31b, the storage area on the upper surface of the shelves 20 and 23 can be expanded toward the support member 30, which can also improve the appearance design.

[0169] <Other Implementation Methods>

[0170] Figures 11-23 The second to seventh embodiments of the present invention are shown. Hereinafter, the description will focus on the points that are substantially different from the embodiments already described.

[0171] Figure 11 (a) and (b) represent the mounted portion 5 and the inner mounting component 40 of the second embodiment, corresponding to the section along the inner side of the casing. Figure 6 The cross-sections of the XI-XI line and the Xc-Xc line.

[0172] That is, firstly, Figure 11 The opening 6′ of the installed part 5 in (a) and Figure 6 Unlike the opening 6, the bridging part 5a is not provided (because it is not divided into upper and lower sections), forming a continuous opening 6′.

[0173] like Figure 11As shown in (b), the mounting component 40 inside the box is integrally provided with positioning portions St1' and St2 that fit into the edges on both sides of the opening 6' in the width direction. Positioning portions St1' and St2 are positioned at both ends of the main surface 40a in the width direction, longitudinally connected to the longitudinal ribs 48a to 48d, and extend to the outer side of the box beyond the opening 6'. The protruding length of positioning portion St1' is greater than... Figure 6 The positioning part St1 is set to abut against another main face 50a.

[0174] In addition, the positioning parts St1′ and St2 are arranged in multiple locations (e.g., the same number of locations as the insertion parts 41) in a manner corresponding to the multiple insertion parts 41 in the length direction of the mounting part 40 inside the box.

[0175] Therefore, when the inner mounting component 40 is inserted into the opening 6′, it can be positioned relative to the inner box 2a at multiple locations along its length by means of the positioning parts St1′ and St2. Furthermore, in this case, by first... Figure 11 The flange 46 of (a) is inserted into the outside of the box, and then inserted from the positioning part St1′ along the edge of the opening 6′, so that the mounting part 40 can be inserted into the inside of the box more easily.

[0176] Figure 12 The outer mounting component 60 shown in (a) and (b) is combined with the inner mounting component 40 of the box.

[0177] like Figure 12 As shown in (a), the outer mounting component 60 of the box is set to the same thickness throughout the width of its main face 60a.

[0178] Furthermore, in the mounting components 40 and 60 of this second embodiment, Figure 6 The engagement recess 42 and engagement protrusion 52 shown are, for example, paired with... Figure 5 Seven pairs of seven clearance recesses 51 are provided in a corresponding manner. Additionally, Figure 6 The pairs of engaging recesses 43 and engaging protrusions 53 shown are arranged laterally with the pairs of engaging recesses 42 and engaging protrusions 52, for example, three pairs are arranged at equal intervals. That is, since there are three pairs of engaging recesses 43 and engaging protrusions 53, they are arranged every other pair relative to the seven pairs of engaging recesses 42 and engaging protrusions 52.

[0179] Thus, the pairs of engaging recesses 43 and engaging protrusions 53, and the pairs of engaging recesses 42 and engaging protrusions 52, which are laterally arranged in the mounting components 40 and 60, are arranged as follows: Figure 12 The shapes shown in (a) and (b) are as follows.

[0180] Here, in Figure 12In (a) and (b), for ease of explanation, the mounting components 40 and 60 on the right are indicated. Figure 12 The sliding direction indicated by the arrow in (b) is the same as Figure 10 The arrows point in the same direction (from the front to the inside).

[0181] In addition, Figure 12 In (a) and (b), the states before and after engagement, i.e., before and after sliding, are used in... Figure 10 The symbols used in (a) and (b) represent the engaging recesses 42 and 43 and the engaging protrusions 52 and 53. Strictly speaking, in Figure 12 In method (b), with Figure 10 Compared to methods (a) and (b), for example Figure 10 The shape of the partition wall 58 near (a) is slightly different, but it can be said to be essentially the same. Figure 10 The engaging recesses 42 and 43 and engaging protrusions 52 and 53 of (a) and (b) are arranged side by side in a transverse arrangement.

[0182] like Figure 12 As shown in (a) and (b), the first blocking part 48 of this second embodiment and Figure 10 Similar to the first blocking portions 481 and 482 in (a) and (b), the front ends of the longitudinal ribs 48b and 48c serve as sealing surfaces. Furthermore, together with the second blocking portion 483, which serves as a sealing surface at both ends of the main surface area 40a in the width direction (on the sides of the longitudinal ribs 48b and 48c), a double blocking structure is formed. In this case, soft strips 8 are provided at the joint portions of the longitudinal ribs 48b and 48c with the opposing main surface area 60a, and at the joint portions of the edge 40e of the main surface area 40a with the peripheral edge of the opposing opening 6′, respectively, to suppress leakage of the foamed insulation material 3a.

[0183] Furthermore, the second blocking portion 483 is composed of a peripheral portion 40e that is formed in descending order along the entire circumference of the main face portion 40a (see reference). Figure 8 (a) and Figure 12 (a) Therefore, the second blocking part 483 is in a configuration that surrounds the entire first blocking part 48, and is closely attached to it via the soft band 8 on the entire circumference of the opening 6′ periphery.

[0184] As explained above, the second blocking part 483 of this second embodiment surrounds the entire first blocking part 48 and is joined to it via a soft band 8 around the periphery of the opening 6′. Therefore, even if the foamed insulation material 3a is not blocked by the first blocking part 48, it can be effectively blocked by the second blocking part 483 to prevent leakage from the opening 6′ into the internal space of the box.

[0185] Furthermore, in the mounting components 40 and 60, the engaging recesses 43 and engaging protrusions 53 are arranged laterally, and the engaging recesses 42 and engaging protrusions 52 are arranged more horizontally than each other. Figure 6 The increased number of mounting parts results in a more robust assembly. In this case, the sliding movement of the mounting component 60 allows the engaging recesses 42, 43 and engaging protrusions 52, 53 to engage simultaneously, simplifying the assembly process and achieving the same effect as the first embodiment.

[0186] Figure 13 and Figure 14 The third embodiment represents the engaging recesses 42 and 43, the engaging protrusions 52 and 53, the anti-detachment portion 59, and the anti-detachment portion 49.

[0187] In the mounting components 40 and 50 of this third embodiment, similar to the second embodiment, for example, seven pairs of engaging recesses 42 and engaging protrusions 52 are provided, and for example, three pairs of engaging recesses 43 and engaging protrusions 53 are provided. Therefore, among the seven pairs of engaging recesses 42 and engaging protrusions 52, the pairing of engaging recesses 42 and engaging protrusions 52 is similar to the pairing of engaging recesses 43 and engaging protrusions 53. Figure 13 They are arranged horizontally in pairs like that.

[0188] Strictly speaking, in Figure 13 In the way, with Figure 10 Compared to methods (a) and (b), for example Figure 10 The shape of the partition wall 58 near (a) is slightly different, but it can be said to be essentially the same. Figure 10 The engaging recesses 42 and 43 and engaging protrusions 52 and 53 of (a) and (b) are arranged side by side in a transverse arrangement.

[0189] In addition, Figure 13 As indicated by reference numerals "42, 50b" in the attached drawings, the position of the engaging recess 42 in the mounting components 40, 50 and the position of the rib 50b surrounding the engaging recess 42 are positioned such that... Figure 10 In case (a), the opening is offset outward in the width direction. To address this offset, a flexible band 8 can be provided at the junction of the edge 40e of the main face 40a and the periphery of the opposite opening 6.

[0190] Furthermore, among the seven pairs of engaging recesses 42 and engaging protrusions 52 in the mounting components 40 and 50, the pair of engaging recesses 42 and engaging protrusions 52 located on the lowest side (and) Figure 6 The lowermost engaging recess 42 and engaging protrusion 52 are positioned in a horizontally arranged manner, and are provided with... Figure 14 The anti-detachment part 59 and the anti-detachment part 49 shown are paired.

[0191] Specifically, such as Figure 14 As shown in (a), on the main surface 50a of the mounting member 50, an opening 52b' is formed that connects to the opening 52b around the engaging protrusion 52 and expands in the front-back direction as the width direction, and an anti-detachment part 59 is integrally formed with the middle part of the width direction of the opening 52b and 52b' as the base.

[0192] The anti-slip part 59 has on its front end side Figure 14 As shown in (a), the burr 59a appears hook-shaped when viewed from the thickness direction of the main face 50a. Additionally, the anti-slip portion 59 has a directional... Figure 14 The thickness of the main face 40a (protruding along the direction perpendicular to the engagement direction) on the inner side of the box shown in (b).

[0193] In contrast, the anti-detachment part 49 is located in the... Figure 14 The slightly concave portion of the main face 40a shown in (b) has a locking rib 49a with a protrusion 59a on the main face 50a that locks off the anti-slip portion 59.

[0194] When mounting components 40 and 50 are assembled, one mounting component 50 is positioned near the front in the sliding direction such that a portion protruding inward from its anti-detachment portion 59 is housed within the concave space of the anti-detachment portion 49. Furthermore, as the mounting component 50 moves in the sliding direction, the front end of the anti-detachment portion 59 abuts against the locking rib 49a and flexes, reaching the aforementioned fixed position (as described above). Figure 14 At the moment when the anti-slip part 59 crosses the position as shown in (b), the burr 59a of the anti-slip part 59 is inserted into the locking rib 49a and locked, giving a sense of rhythm.

[0195] Thus, the anti-detachment part 59 and the anti-detachment part 49 are temporarily engaged by the sliding movement of the mounting member 50 through other engaging recesses 42, 43 and engaging protrusions 52, 53 (see reference). Figure 13 They engage with each other without disengaging.

[0196] In addition, by sliding the mounting part 50 to a fixed position that provides a sense of rhythm, the anti-detachment part 59 can be reliably locked onto the anti-detachment part 49.

[0197] As explained above, the anti-detachment part 59 of this third embodiment is integrally formed with one of the mounting members 50, for example having a burr 59a, and is prevented from falling off in the opposite direction of the engagement direction by the other mounting member 40 (for example, by the locking rib 49a of the anti-detachment part 49).

[0198] Thus, the anti-detachment part 59 hooks its burr 59a onto the locking rib 49a. Therefore, it functions similarly to the anti-detachment part 54a in the first embodiment, thus achieving the same effect as the above-described embodiment, such as maintaining the two mounting parts 40 and 50 in a combined state.

[0199] Figures 15-17 The mounting components 70 and 80 and the insertion plate 85 of the fourth embodiment are indicated. The mounting components 70 and 80 of this fourth embodiment differ from the mounting components 40 and 50 of the first embodiment in the following aspects.

[0200] That is, such as Figure 16 As shown, seven engaging protrusions 71 and 72 are integrally formed on the mounting member 70 inside the box. The engaging protrusions 71 and 72 are arranged alternately with the inserted part 41 in the longitudinal direction of the mounting member 70.

[0201] Here, Figure 17 Is along Figure 15 The corresponding cross-sectional view along the XVII-XVII line shows the vicinity of the engaging protrusions 71 and 72 of the mounting components 70 and 80. Additionally, in... Figure 17 In the diagram, for ease of explanation, mounting components 70 and 80 of the specifications on the right are shown (refer to the arrows pointing forward and backward), which is consistent with... Figure 15 , Figure 16 The mounting components 70 and 80 on the left side are different, but the insertion direction (from the front side to the inside) of the insertion plate 85 described later for either specification is the same.

[0202] like Figure 17 As shown, the engaging protrusions 71 and 72 extend outward from the inner casing 2a, with both ends of the main surface 70a in the width direction (front-back direction) as their bases. In this case, the engaging protrusion 71 on the front side has a forward-folding burr 71a on its front end side, forming an approximately "L" shape, while the engaging protrusion 72 on the inner side has an inward-folding burr 72a on its front end side, forming an approximately "U" shape. In this case, the engaging protrusion 71 is configured such that its burr 71a is larger than the burr 72a of the engaging protrusion 72, and it first inserts into the opening 6 of the inner casing 2a (the engaging recess 81 of the mounting member 80).

[0203] Furthermore, the engaging protrusions 71 and 72, like the longitudinal ribs of the aforementioned blocking portion 48, are located at both ends in the width direction where they engage with the opening 6 of the inner box 2a, through... Figure 16 The upper and lower transverse ribs 48r shown and the engaging protrusions 71 and 72 at both ends form a frame shape, constituting a blocking structure. That is, this blocking structure is equivalent to surrounding... Figure 17The first blocking part 480, which is composed of a pair of transverse ribs 48r and engaging protrusions 71 and 72, is located in the designated space S3 between the mounting components 70 and 80 shown.

[0204] on the other hand, Figure 16 The mounting component 80 on the outside of the box shown has seven engaging recesses 81 formed at approximately equal intervals along its length, corresponding to the seven engaging protrusions 71 and 72 mentioned above.

[0205] like Figure 16 , Figure 17 As shown, the engaging recess 81 has: a rectangular opening 81a (connecting hole) that matches the frame shape of the engaging protrusions 71 and 72; and stepped portions 811 and 812 on the outer side of the box, formed on both sides of the opening 81a in the width direction of the main surface 80a.

[0206] The stepped portion 811 is formed by a relatively shallow groove extending along the length of the mounting member 80, connecting the near-front sides of each opening 81a, and descends to a lower level on the outer side of the main face 70a. In this case, in order to accommodate the insert plate 85, the length and width dimensions of the stepped portion 811 are set to be slightly larger than the insert plate 85.

[0207] The stepped section 812 is composed of seven stepped sections located on the inner side of each opening 81a, which descend in steps on the outer side of the main face 70a.

[0208] Figure 16 The insert plate 85 shown is a long and narrow thin plate that can be housed in the step portion 811. The insert plate 85 has seven cutout portions 85a at seven locations, with one end of its width direction aligned with the arrangement of the engaging protrusions 71.

[0209] Furthermore, the mounting components 70 and 80 can be assembled in a manner that does not create gaps around the opening 6 by using the insert plate 85 when assembling into the inner box 2a.

[0210] That is, when assembling and installing components 70 and 80, the mounting component 80 is first placed on the outside of the box of the part to be installed 5, so that the engaging protrusions 71 and 72 of the mounting component 70 engage with the engaging recesses 81 of the mounting component 80 from the inside of the box through the opening 6 of the inner box 2a.

[0211] In this case, the mounting component 70 first tilts the large engaging protrusion 71 of the flash 71a so that it passes through the opening 6 and engages with the stepped portion 811 of the engaging recess 81. Then, using the engaging protrusion 71 side as a fulcrum, the mounting component 70 is rotated outwards in a manner that mates with the wall of the inner box 2a. At this time, the insertion plate 85 has not yet been inserted into the stepped portion 811, and the small engaging protrusion 72 of the flash 72a abuts against the opening 6 and flexes, reaching the fixed position (e.g., Figure 17 At the moment when the opening 81a is crossed, the burr 72a is embedded in the step portion 812 and is stopped.

[0212] In this state, the insertion plate 85 is configured such that its cutout 85a faces inward, and as... Figure 15 As shown, the flash 71a and the cutout 85a are aligned vertically to offset each other, and then the flash 71a is inserted into the lower side of the step 811 from the front side (see reference). Figure 17 ).

[0213] Alternatively, the insert plate 85 is pressed and stored toward the step portion 811 such that its cut portion 85a is aligned with the burr 71a, or by directly sliding the insert plate 85 downwards (e.g., ...). Figure 15 (Move it to the underside of the flash 71a with the cut 85a exposed) and it can be easily inserted into the underside of the flash 71a.

[0214] As explained above, the mounting member 70 of this fourth embodiment is in the flexural direction of the engaging protrusions 71 and 72 (e.g., Figure 17 When viewed from the outer side of the width direction of the component 70 (as shown in the front-back direction), which is the engagement direction, the engagement protrusions 71 and 72 can be described as anti-detachment portions protruding from the mounting component 80 in a direction perpendicular to the engagement direction. That is, the engagement protrusions 71 and 72 with burrs 71a and 72a are integrally formed with the mounting component 70, and are prevented from falling off in the opposite direction of the engagement direction by another mounting component 80 (e.g., the stepped portions 811 and 812 of the engagement recess 81).

[0215] Thus, for example, the engaging protrusions 71 and 72 function as anti-detachment parts by hooking their burrs 71a and 72a onto the engaging recess 81, thereby maintaining the state in which the two mounting parts 70 and 80 are assembled together.

[0216] Furthermore, the insertion plate 85 can be inserted in a manner that prevents play in the portion of the flash 71a and even around the engaging protrusions 71 and 72. Additionally, it can ensure, for example, compliance with the flexibility of the engaging protrusions 71 and 72. Figure 16 The sealing function of the sealing surface in the blocking structure, including the transverse rib 48r.

[0217] Furthermore, for example, even if the foamed insulation material 3a is from Figure 17 The opening 81a of the mounting component 80 shown can be used to block the foamed insulation material 3a from flowing into the box space from the designated space S3, thus achieving the same effect as the above embodiment.

[0218] Figures 18-22 The mounting components 90 and 100 are indicated in the fifth embodiment.

[0219] Here, Figure 18 as well as Figure 20 This is a perspective view of the lower and central portions of the refrigerator as seen from the outside, showing the assembled components 90 and 100. Figure 19 (a) and (b) are perspective views showing the upper and lower portions of mounting components 90 and 100 cut apart. Figure 22 It is along Figure 20 The cross-sectional view along line XVII-XVII shows the engaging protrusions 91 and 92 of the mounting component 90.

[0220] In the mounting component 90 inside the box, such as Figure 21 As shown, between the multiple insertion portions 41 arranged vertically on the main face 90a, engaging protrusions 91, 91 and cylindrical ribs 92 are provided, or in Figure 19 A square tube rib 93 is provided at the lower end of the main face 90a (the lower side of the inserted part 41) shown in (b).

[0221] The square tube rib 93 of this fifth embodiment can be provided with one or more engaging protrusions instead of engaging protrusions 91, 91. That is, by adopting a structure in which only one of the square tube rib 93 and engaging protrusions 91, 91 are selectively provided as engaging protrusions, the number and arrangement of these engaging protrusions can also be appropriately changed. Therefore, the following description will be divided into the square tube rib 93 and engaging protrusions 91, 91.

[0222] That is, firstly, the square tube rib 93, as Figure 18 , Figure 19 As shown in (b), one is formed at the lower end of the main face 90a of the mounting component 90, or another is formed in the middle part in the vertical direction.

[0223] The square tube rib 93, for example, has a square longitudinal section, and its front end extends outward from the opening 6c of the inner box 2a to the outer surface of the mounting member 100. Additionally, as... Figure 18 , Figure 19 As shown in (b), on the front end side of the square tube rib 93, the tongue portion 93a hanging down from the lower edge of the square tube rib 93 is formed as a protrusion that protrudes into the heat insulation space.

[0224] An opening 103 is formed in the mounting component 100 on the outside of the box at a position corresponding to the square tube rib 93.

[0225] like Figure 18 , Figure 19 As shown in (b), the opening 103 is a snap-fit ​​recess formed by cutting the main face 100a of the mounting component 100 into a square, and the tongue portion 93a of the square tube rib 93 is inserted into and snapped onto the outside of the box.

[0226] In this way, the tongue portion 93a of the square tube rib 93 engages with the opening 103 through the opening 6c of the inner box 2a, thereby assembling the mounting components 90 and 100 together. In this case, it is possible to achieve an engaged state in which the square tube rib 93 blocks the opening 103 of the mounting component 100.

[0227] The opening 103 is equivalent to a connecting hole that connects the specified space inside the mounting components 90 and 100 with the heat insulation space. The specified space (the interior of the square tube rib 93) is surrounded by the square tube rib 93, which protrudes from one mounting component 90 to another mounting component 100 as a first blocking part.

[0228] In addition to being fixed by the engagement of the square tube rib 93 at its lower end with the opening 103, the mounting components 90 and 100 are also fixed by the screw 7 at their upper end with the boss portion 45 (see reference). Figure 19 (a) In addition, if a boss 45 is provided in the middle part in the vertical direction, a structure in which the screw 7 is used for fixing can be adopted, thus fixing can be achieved at three locations. Furthermore, the mounting components 90 and 100 can also adopt the following structure: in addition to their lower ends, a square tube rib 93 and an opening 103 are provided in the middle part in the vertical direction, thereby fixing can be achieved at three locations, including fixing at the upper end based on the screw 7 to the boss 45.

[0229] Furthermore, in this fifth embodiment, the openings 6a to 6c of the mounted portion 5' are... Figure 6 The opening 6 is different, including Figure 19 The protrusion portion has an opening 6a, the insertion portion has an opening 6b, and the engaging portion has an opening 6c, as shown in (a) and (b). That is, the openings 6a, 6b, and 6c correspond to the number of the protrusion portion 45, the insertion portion 41, the square tube rib 93, etc., that penetrate the inner box 2a, and are individually opened according to their respective shapes. Furthermore, as shown in... Figure 22 As shown, the area around the mounted portion 5' is not flat, unlike the mounted portion 5 in the embodiment described above, but details are available in [the document / section]. Figure 23 This will be discussed later.

[0230] like Figure 21 , Figure 22As shown, the engaging protrusions 91 and 91 extend outward from the center of the main surface 90a in the width direction, respectively, compared to the inner casing 2a. In this case, the engaging protrusions 91 and 91... Figure 17 Compared to the engaging protrusions 71 and 72, the engaging part of the inner box 2a is located near the center in the width direction, and the opening 6c is also formed to be narrow.

[0231] Furthermore, the protrusion of the engaging protrusions 91, 91 towards the outside of the refrigerator is set to not exceed the outer surface of the mounting member 100 (main surface 100a). The engaging protrusions 91, 91... Figure 21 The axis 400 shown is formed symmetrically as an axis of symmetry, and the shapes of the finials 91a, 91a at their respective tops are also formed symmetrically in a way that they hook outwards in the width direction.

[0232] A second blocking portion 48' is provided on the main face 90a of the mounting component 90 inside the box, surrounding the engaging protrusions 91, 91 (only on the main face 90a of the mounting component 90 inside the box). Figure 22 (See diagram). Although detailed illustrations are omitted, the second blocking portion 48' is formed into a rectangular frame shape in the main face 90a by longitudinal and transverse ribs surrounding the base end sides of the engaging protrusions 91 and 92. Thus, the front end side of the ribs constituting the second blocking portion 48' is formed as a sealing surface that engages with the periphery of the opening 6c and overlaps with the inner box 2a, and is covered with a soft strip 8.

[0233] On the main surface 100a of the mounting member 100 on the outside of the box, an opening 101 is formed as an engaging recess that engages with engaging protrusions 91, 91. That is, as Figure 20 , Figure 22 As shown, the outer side of the main face 100a is recessed except for its outer periphery and the avoidance recess 51. An opening 101 is provided in the recessed area to form a locking recess for receiving the burrs 91a and the locking recess of the locking protrusions 91 and 91a.

[0234] Furthermore, the opening 101 is equivalent to a connecting hole that connects the designated space inside the mounting components 90 and 100 with the heat insulation space, but a first blocking portion 910 is integrally formed at the base end of the engaging protrusions 91 and 91. That is, as Figure 21 , Figure 22As shown, the first blocking portion 910 is a portion of the square tube on the base end side of the engaging protrusions 91, 91, the front end of which is configured to protrude from the main face portion 90a in a manner that engages with the opening 101. For example, four pairs of such engaging protrusions 91, 91 and openings 101 are provided at equal intervals along the length direction of the mounting members 90, 100. When the mounting members 90, 100 are assembled, the engaging protrusions 91, 91 are aligned with the opening 101 at the mounted portion 5′, allowing the two mounting members 90, 100 to align with each other in the thickness direction and engage with the opening 101. Furthermore, as described above, the engaging protrusions 91, 91, 91, Figure 17 The engaging protrusions 71 and 72 are flexible, and the desired engaging state can be confirmed by the tactile sensation or sound when they engage.

[0235] Additionally, on the outer side of the box indicating the mounting component 100 Figure 20 and Figure 18 In this case, the shapes of the avoidance recesses 51 and 51' are different. This is because the avoidance recess 51 forms a space to avoid interference with the claw portion 33, therefore... Figure 19 of (a), Figure 18 As shown, an example of the shape of the avoidance recess 51' is shown, in which the thickness of the plate of the main face 100a is formed to match the shape of the inserted portion 41.

[0236] Here, as Figure 19 (b) Figure 22 As shown, the outer wall portion on the heat insulation space side of the clearance recesses 51 and 51' is formed as an outer box protrusion 51a and 51a' that protrudes towards the heat insulation space side from the main surface portion 100a, corresponding to the recess of the clearance recesses 51 and 51'. Furthermore, Figure 22 The outer peripheral rib 51a″ shown is also integrally formed on the outer periphery of the main face 100a and protrudes toward the heat insulation space side compared to the main face 100a, and is therefore also called the outer side protrusion 51a″.

[0237] These outer protrusions 51a, 51a′, and 51a″ are set to a protruding length that extends to the vicinity of the vacuum insulation plate 3b, compared to the protrusions of the inner mounting parts 90 such as the engaging protrusions 91 and 91.

[0238] In this case, such as Figure 20 , Figure 22 As shown, the engaging protrusions 91, 91 are positioned between the outer protrusions 51a, 51a′ and surrounded by the outer peripheral rib 51a″. The outer protrusions 51a, 51a′ and the outer peripheral rib 51a″ are formed to be slightly smaller than the engaging protrusions 91, 91. Figure 22 The amount of ΔL shown protrudes towards the insulation space side.

[0239] same, Figure 19 The tongue portion 93a of the square tube rib 93 shown in (b) is also in a configuration where it is sandwiched or surrounded by the outer side protrusions 51a, 51a′, 51a″, and the protrusion length of the outer side protrusions 51a, 51a′, 51a″ toward the heat insulation space is greater than that of the tongue portion 93a.

[0240] Figure 21 The cylindrical rib 92 shown is, for example, a positioning rib formed in the middle of the vertical direction of the main surface 90a of the mounting member 90. The cylindrical rib 92 has, for example, a circular longitudinal section, and its front end protrudes through the opening (not shown) of the inner box 2a to the large-diameter rib 102 (see reference 102) of the mounting member 100. Figure 20 The inner surface side of the surface is extended in a manner.

[0241] The large-diameter rib 102 is a bottomed cylindrical shape in which its inner circumferential surface slides in contact with the outer circumferential surface of the cylindrical rib 92, and is integrally formed on the main surface 100 of the mounting component 100. Thus, in the assembly of the mounting components 90 and 100, the large-diameter rib 102, by being embedded in the cylindrical rib 92, can achieve a positioning effect between the mounting components 90 and 100, thereby improving the assembly accuracy.

[0242] As explained above, the mounting member 90 of this fifth embodiment is in the flexural direction of the engaging protrusions 91, 91 (e.g.) Figure 22 When viewed from the outer side of the width direction of the component 90 (as shown in the front-back direction), which is the engagement direction, the engagement protrusions 91, 91 can be described as anti-detachment portions protruding from the mounting component 80 in a direction perpendicular to the engagement direction. That is, the engagement protrusions 91, 91 with burrs 91a, 91a are integrally formed with the mounting component 90, and are prevented from falling off in the opposite direction of the engagement direction by another mounting component 100 (e.g., the periphery of the opening 101).

[0243] Thus, for example, the engaging protrusions 91, 91 function as anti-detachment parts by hooking their burrs 91a, 91a around the periphery of the opening 101, thereby maintaining the state in which the two mounting parts 90, 100 are combined with each other.

[0244] Additionally, because the mounting component 90 inside the box is provided with, for example... Figure 19 (b) shows the square tube rib 93 as the first blocking part. Figure 22 The first blocking part 910 and the second blocking part 48' shown thus achieve the same effect as the above embodiment, such as being able to suppress the intrusion of the foamed insulation material 3a into the box space.

[0245] In addition, Figure 22The figure shows the positional relationship between the vacuum insulation panel 3b and the foamed insulation material 3a in the insulation space and the mounting components 90 and 100. As shown in the figure, there is a gap between the vacuum insulation panel 3b and the mounting component 100 on the outside of the refrigerator. In addition, assuming there are small gaps around the engaging protrusions 91 and 91 of the opening 101, even if the foamed insulation material 3a flows into the refrigerator through these gaps along the engaging protrusions 91 and 91, the first blocking part 910 on the base end side of the engaging protrusions 91 and 91 can block the foamed insulation material 3a, or the sealing surface of the second blocking part 48' on its outer periphery can block the foamed insulation material 3a, so that the foamed insulation material 3a will not flow into the refrigerator space.

[0246] The outer mounting component 100 of the box has outer protrusions 51a, 51a′, and 51a″, each of which is at least one outer protrusion 51a, 51a′, and 51a″, configured to surround or clamp the protrusions (e.g., engaging protrusions 91, 91, and square tube ribs 93) of the inner mounting component 90 of the box, and protrudes to the vicinity of the vacuum insulation material compared to the protrusions.

[0247] Therefore, even if the component 90 installed inside the box has a protrusion extending into the heat insulation space (e.g., Figure 22 The engaging protrusions 91, 91, etc. can also ensure the distance between the front end of the protrusion and the vacuum insulation material through the outer protrusions 51a, 51a′, 51a″, suppressing the risk of damage to the vacuum insulation material.

[0248] In addition, as a protrusion for mounting components inside the box, for example including Figure 17 The engaging protrusions 71 and 72 are configured to protrude into the heat insulation space.

[0249] Figure 23 A cross-sectional view showing the area near the mounted portion 5′ of the inner casing 2a in the sixth embodiment.

[0250] As shown in the figure, a raised portion 9 is formed on the side wall of the inner casing 2a, slightly bulging around the mounted portion 5'. The raised portion 9 protrudes further into the casing than the side wall (the straight line labeled 2a in the figure). In this case, the amount of protrusion of the raised portion 9 is smaller than the thickness of the plate of the mounting member 90 inside the casing; for example, the maximum amount of protrusion on the side of the mounted portion 5' shown in the figure is approximately half the thickness of the plate of the mounting member 90.

[0251] Furthermore, the raised portion 9 symmetrically protrudes on the working side and the inner side, separated from the mounting portion 5'. Thus, the raised portion 9 on the front side protrudes towards the inside of the box in such a way that it forms a gently sloping surface from its working side toward the mounting portion 5', while the raised portion 9 on the inner side protrudes towards the inside of the box in such a way that it forms a gently sloping surface from its inner side toward the mounting portion 5'.

[0252] As explained above, the mounted portion 5′ of this sixth embodiment has a relatively concave shape due to the raised portions 9 on both the front and rear sides, so that at least a portion of the inner mounting member 90 is hidden when viewed from the front of the refrigerator 1. In addition, in this case, by making the inner mounting member 90 thinner and increasing the amount of the raised portion 9 below it, the internal space is not substantially reduced, and the appearance design can be improved.

[0253] In addition, although the illustration is omitted, a raised portion that bulges towards the inside of the box can also be symmetrically formed on the upper and lower sides of the mounting portion 5′, so as to form a gently sloping surface towards the mounting portion 5′.

[0254] The foregoing has described one embodiment of the present invention, but this embodiment is provided as an example and is not intended to limit the scope of the invention. These new embodiments can be implemented in various other ways, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, and are included in the scope of the invention described in the patent claims and its equivalents.
