In addition, when the sealing material is attached to the heat insulating box during assembly line work, the positioning accuracy of the sealing material varies depending on the skill of the operator. Therefore, when the positioning accuracy of the seal is poor, in the process of filling and foaming the foam insulation material into the space between the outer box and the inner box, the seal may be damaged due to the foaming pressure of the foam insulation material. The problem point where the foam insulation material is squeezed out and leaks out.

In addition, the refrigerator described in Patent Document 2 has a structure in which the shelf support attachment member is attached to the inner box by fitting the screw receiving portion into the through hole of the inner box. Therefore, there is a problem that the shelf support mounting member comes off and the foam heat insulating material leaks out in the foam filling process of the foam heat insulating material. Also, Patent Document 2 discloses a structure in which the shelf support attachment member is attached to the inner box with an adhesive, but when the shelf support attachment member is attached to the inner box with an adhesive, There is a problem that it takes time to dry the adhesive, which increases man-hours. In addition, in the structure in which the shelf support mounting member is attached to the inner box with an adhesive, since the application accuracy of the adhesive varies depending on the operator, when the amount of the adhesive applied is small, However, in the foam filling process of the foam heat insulation material, the problem of leakage of the foam heat insulation material still cannot be eliminated. And, for the refrigerator described in Patent Document 2, it is formed to install the internal parts (the shelf support in Patent Document 2) by screwing the screw into the threaded part of the screw receiving part of the shelf support mounting member. )Structure. Therefore, in the refrigerator described in Patent Document 2, there are problems that burrs caused by thread cutting remain in the storage compartment when installing the inner parts, and there are problems that the number of man-hours for installing the inner parts increases.

Moreover, the opening part in front of the heat insulation box 1a is closed with the left-right opening type or the drawer type door (not shown) corresponding to each store room. In addition, a drawer-type door is often provided with a basket-shaped storage box that moves in the front-rear direction together with the door.

(Detailed structure of the installation structure of the parts in the box)

Next, the detailed structure of the above-mentioned interior component attachment structure 10 which attaches the food shelf 40 is demonstrated using FIGS. 2-4.

The inner case 3 has an inner case convex portion 3 a protruding toward the outer case 2 side, for example, in a substantially quadrangular shape (in other words, formed in a concave shape when viewed from the storage room side and a convex shape when viewed from the outer case 2 side). In addition, an inner case through hole 3b is formed in, for example, a substantially central portion of the inner case convex portion 3a. Each inner member mounting structure 10 includes a bushing 11 and a bushing fixture 16 provided near the inner case convex portion 3 a and mostly buried on the outer case 2 side than the wall surface of the inner case 3 .

The sleeve 11 is arranged to be in contact with the surface of the inner case 3 on the side of the outer case 2 . A sleeve recess 12 into which the inner case protrusion 3 a is inserted is formed on a surface of the sleeve 11 facing the inner case 3 . The shape of the inner peripheral portion of the sleeve concave portion 12 is substantially the same as the shape of the outer peripheral portion of the inner case convex portion 3a. Therefore, by inserting the inner case convex part 3a into the sleeve recessed part 12, the sleeve 11 can be positioned in the up-down direction and the front-back direction of a storage room.

Further, a sleeve convex portion 13 protruding from the inside of the sleeve recess 12 toward the inner case 3 side is formed on a surface of the sleeve 11 facing the inner case 3 . When the inner case convex portion 3 a is inserted into the sleeve concave portion 12 , the sleeve convex portion 13 is inserted into the inner case through hole 3 b of the inner case convex portion 3 a. When the inner case convex portion 3a is inserted into the sleeve concave portion 12, and the outer peripheral portion of the sleeve 12 is in contact with the inner case 3 on the outer peripheral side of the inner case convex portion 3a, the front end portion of the sleeve convex portion 13 becomes A state that protrudes slightly from the wall surface of the inner box 3 . A holding recess 14 that opens toward the front end side of the sleeve protrusion 13 (that is, opens toward the storage compartment side) is formed in the sleeve protrusion 13 . The holding recessed portion 14 is a portion that holds (clamps) an attachment portion (for example, a holder 19 described later) of an in-box attachment member. Therefore, the opening shape of the retaining recess 14 , that is, the cross-sectional shape of the retaining recess 14 perpendicular to the protruding direction of the sleeve protrusion 13 is formed in a shape compatible with the mounting part (for example, the holder 19 described later) of the mounting member in the box. The corresponding shape (such as a horizontally long cuboid shape).

In addition, the sleeve 11 has an engaging pawl 15 that engages with a notch 18 of a sleeve holder 16 described later at the front end portion of the sleeve protrusion 13 . In addition, the sleeve 11 has a flange 11 a that contacts the inner case 3 on the outer peripheral side of the inner case convex portion 3 a on the outer peripheral portion of the sleeve recessed portion 12 . By forming the flange 11a, the adhesiveness between the sleeve 11 and the inner box 3 is further improved, so that when the foamed heat insulating material 5 is filled into the heat insulating material filling space 4, the foamed heat insulating material 5 can be further suppressed from slipping from the sleeve 11 and the inner box 3. The case of leakage between the boxes 3 towards the storage room side.

The sleeve holder 16 is inserted into the inner case convex portion 3a from the storage room side, and the outer peripheral portion of the sleeve holder 16 is formed in substantially the same shape as the inner peripheral portion of the inner case convex portion 3a. Therefore, by inserting the sleeve holder 16 into the inner case convex portion 3a, the sleeve holder 16 can be positioned in the up-down direction and the front-rear direction of the storage room. In addition, an insertion portion 17 is formed at, for example, substantially the center of the sleeve holder 16 , and a through hole into which the sleeve protrusion 13 of the sleeve 11 is inserted is formed in the insertion portion 17 . At the end of the insertion portion 17 on the side of the storage compartment, there is formed a cutout 18 for engaging with the engaging claw 15 of the sleeve 11 , in other words, for hooking the engaging claw 15 of the sleeve 11 . That is, by inserting the sleeve convex portion 13 of the sleeve 11 into the insertion portion 17 and engaging the engaging claw 15 of the sleeve 11 with the notch 18 of the sleeve fixing member 16, the sleeve 11 and the sleeve fixing member 16 are The inner case 3 (more specifically, the front end surface of the inner case convex portion 3a) can be clamped so that the outer peripheral portion of the sleeve concave portion 12 contacts the inner case 3 as the outer peripheral side of the inner case convex portion 3a. The cylinder 11 is fixed to the inner case 3 . In the state where the inner box 3 is clamped by the sleeve 11 and the sleeve fixing member 16, the front end portion of the sleeve convex portion 13 of the sleeve 11 and the storage room-side end portion of the insertion portion 17 of the sleeve fixing member 16 are located approximately same location.

In addition, as described above, the sleeve 11 is positioned between the sleeve 11 and the inner case convex portion 3a. Therefore, it is not necessary to position the sleeve fixing member 16 between the sleeve fixing member 16 and the inner case convex portion 3a, and the shape of the outer peripheral portion of the sleeve fixing member 16 may be smaller than that of the inner case convex portion 3a. shape. Even if the sleeve holder 16 is formed in this way, the sleeve 11 can be attached to the inner case 3 with high precision.

(How to install the parts inside the box)

Next, the detailed structure of the food shelf 40 which is an interior part attached to the interior part attachment structure 10 is demonstrated.

Fig. 5 is a side view showing a food rack as an example of an interior member of the refrigerator according to Embodiment 1 of the present invention. Moreover, FIG. 6 is a perspective view which shows the installation direction of this food rack.

Hereinafter, the detailed structure of the food rack 40 is demonstrated using FIG.5, FIG.6, and above-mentioned FIG.2-FIG.4.

The food rack 40 further divides the storage room and includes a shelf 42 . Moreover, the food rack 40 which concerns on this Embodiment 1 is also equipped with the holder 19 inserted into the recessed part 14 for holding of the internal component attachment structure 10. As shown in FIG. Furthermore, the shelf plate 42 is configured to be attached to the holder 19 .

As described above, the holder 19 is a member that is inserted into the holding recess 14 of the interior component mounting structure 10 . The width and height of the holder 19 are formed smaller than the width and height of the holding recess 14 . Therefore, even after the holder 19 is inserted into the holding recess 14 , the holder 19 also has a degree of freedom, and when a force is applied, the holder 19 can slide in the holding recess 14 . That is, the holder 19 is slidably held by the holding recess 14 . In the state where the holder 19 is held by the holding recess 14 , the storage compartment-side front end of the holder 19 protrudes to a position closer to the storage compartment than the interior component mounting structure 10 . The holder 19 is formed of, for example, a metal plate, and has, for example, two pin holes 20 through which a pin 41b described later is inserted vertically at a front end portion on the storage compartment side.

As described above, the shelf 42 further divides the storage room, and is formed in a substantially rectangular parallelepiped flat plate shape. A leg portion 41 attached to the holder 19 is formed below the shelf plate 42 . In this Embodiment 1, the food rack 40 is hold|maintained by the two inner member mounting structures 10 provided in each of the two side surfaces of the inner box 3. As shown in FIG. That is, the shelves 42 are held by the holders 19 inserted into the holding recesses 14 of the four interior component mounting structures 10 described above. Therefore, in the shelf plate 42 according to Embodiment 1, the leg portions 41 are formed at positions corresponding to the above-mentioned four interior component attachment structures 10 (that is, four positions). The said leg part 41 is provided with the leg part cover 41a and the pin 41b, respectively. The foot cover 41 a extends downward from, for example, the lower surface of the shelf plate 42 , and is formed in a shape in which the outer side (the side surface of the inner box 3 that faces) is recessed. The pin 41b is inserted into the pin hole 20 of the holder 19 . In Embodiment 1, two pins 41 b are provided corresponding to the number of pin holes 20 . These pins 41b are provided on the side of the foot cover 41a facing the inner case 3, that is, on the side of the recess of the foot cover 41a.

As shown in FIG. 6 , the shelf 42 is moved downward from the top, and the pin 41 b is inserted into the pin hole 20 of the holder 19 from above, whereby the shelf 42 is coupled to the holder 19 in the front, rear, left, and right directions through the holder 19 . It is held in the internal component mounting structure 10 . At this time, the interior component mounting structure 10, the holder 19, and the pin 41b are covered with the foot cover 41a. Therefore, since the user of the refrigerator 1 cannot see the internal component attachment structure 10, the holder 19, and the pin 41b, the refrigerator 1 which has the food rack 40 excellent in appearance can be obtained.

Here, for the heat insulating box 1a, there are various heat insulating boxes due to the accuracy of parts of the outer box 2 and the inner box 3, the pressure applied to the outer box 2 and the inner box 3 in the foaming process of the foamed heat insulating material 5, and the like. There may be deviations in the dimensions of 1a. Therefore, the interior components held by the interior component mounting structures 10 provided on both sides of the inner box 3, such as the food rack 40, may be difficult to attach to the storage room due to the dimensional variation of the heat insulating box 1a. However, by attaching the shelf plate 42 through the holder 19 as in Embodiment 1, even if there is a variation in the size of each heat insulating box 1a, it can be fixed in the holding recess of the internal component mounting structure 10 through the holder 19 . 14 to absorb the dimensional deviation of the heat insulating box 1a, so that the food rack 40 can be reliably attached to the storage room.

(Manufacturing method of heat insulating box)

Next, a method of manufacturing the heat insulating box 1a will be described.

When manufacturing the heat insulating box body 1a, first, the box interior component attachment structure 10 is attached to the inner box 3 (1st process). Specifically, the sleeve protrusion 13 of the sleeve 11 is inserted into the inner case through hole 3b of the inner case protrusion 3a from the outer case 2 side, and the inner case protrusion 3a of the inner case 3 is inserted into the inner case protrusion 3a of the sleeve 11.

On the other hand, the sleeve holder 16 is inserted into the inner case convex portion 3 a from the storage room side, and the sleeve protrusion 13 of the sleeve 11 is inserted into the insertion portion 17 of the sleeve holder 16 . As a result, the engaging claws 15 of the sleeve 11 engage with the cutouts 18 of the sleeve holder 16 , and the sleeve 11 can be held by the sleeve holder 16 . In other words, the inner case 3 (more specifically, the front end surface of the inner case convex portion 3 a ) can be sandwiched by the sleeve 11 and the sleeve holder 16 .

At this time, the sleeve 11 can be positioned between the sleeve 11 and the inner case convex portion 3a, and the sleeve fixing member 16 can be positioned between the sleeve fixing member 16 and the inner case convex portion 3a. Positioning of the inner component mounting structure 10 becomes easy. And, by clamping the inner case 3 (more specifically, the front end surface of the inner case convex portion 3a) by the sleeve 11 and the sleeve holder 16, the outer peripheral portion of the sleeve recess 12 (more specifically, the flange 11a ) is in contact with the inner case 3 which is the outer peripheral side of the inner case convex portion 3 a. That is, in the box interior component mounting structure 10 according to the first embodiment, the tightness between the sleeve 11 and the inner box 3 can be ensured only by engaging the sleeve 11 with the sleeve holder 16 . Therefore, unlike the conventional ones, the box interior component mounting structure 10 according to the first embodiment does not need to attach a sealing material or apply an adhesive to ensure the adhesiveness between the sleeve 11 and the inner box 3 . Therefore, in the case internal component mounting structure 10 according to the first embodiment, the adhesiveness between the sleeve 11 and the inner case 3 can be ensured without being affected by the operator's work deviation. In the filling process of the foam heat insulating material 5 , it is possible to stably prevent the leakage of the foam heat insulating material 5 .

In addition, the installation work of the above-mentioned box internal component installation structure 10 may be performed on a stationary workbench, or may be performed in a line operation while conveying the inner box 3 by a belt conveyor.

After the inner box component mounting structure 10 is attached to the inner box 3, the inner box 3 and the outer box 2 are combined. Furthermore, the raw material of the foamed heat insulating material 5 is injected into the heat insulating material filling space 4 between the inner peripheral side of the outer case 2 and the outer peripheral side of the inner case 3 and foamed, and the foamed heat insulating material is filled into the heat insulating material filling space 4 . Material 5 (second process). As described above, in the box internal component mounting structure 10 according to the first embodiment, the adhesiveness between the sleeve 11 and the inner box 3 can be ensured without being affected by the operator's work deviation. In the filling process of the foam heat insulating material 5 , it is possible to stably prevent the leakage of the foam heat insulating material 5 .

As mentioned above, in the refrigerator 1 comprised as this Embodiment 1, the box interior component attachment structure 10 can be easily attached to the inner box 3 only by engaging the sleeve 11 with the sleeve holder 16. As shown in FIG.

The heat-insulating box 1a of the refrigerator 1 according to the second embodiment includes an outer case 2 mainly constituting the outer peripheral surface of the heat-insulating box 1a ; The material fills the vacuum insulation material 6 of the space 4 and the foam insulation material 5 . The vacuum insulation material 6 is bonded and fixed to the inner side of the outer box 2 by means of double-sided adhesive, hot melt adhesive or the like. The raw material of the foamed heat insulating material 5 is injected between the inner peripheral side of the outer case 2 and the outer peripheral side of the inner case 3, and the raw material is foamed in the entire heat insulating material filling space 4 within the range where the vacuum heat insulating material 6 is not arranged, The foam insulation material filling space 5a between the vacuum insulation material 6 and the inner box 3 within the range of the vacuum insulation material 6 is made to foam the raw material, and by filling the foam insulation material 5 into these spaces, the outer box 2 and the inner box 3 are connected. combine together.

In addition, in the heat insulating box 1 a according to the second embodiment, a condensation pipe (not shown) that undertakes the condensation process in the refrigeration cycle system is attached to the inner side surface of the outer case 2 with aluminum tape or the like. Therefore, in the vacuum heat insulating material 6 provided in the range facing the condensation pipe, the vacuum heat insulation material 6 is formed with a groove-shaped condensation pipe avoidance portion 8 so that the vacuum heat insulation material 6 straddles the condensation pipe.

Furthermore, in the heat insulating box 1a according to Embodiment 2, the thickness of the vacuum heat insulating material 6 having low thermal conductivity is increased as much as possible in order to minimize the wall thickness (insulation thickness) of the heat insulating box 1a. Therefore, the foam insulation flow path width 7 (interval between the vacuum insulation material 6 and the inner box 3 ) of the foam insulation material filling space 5 a is suppressed to the minimum width that can ensure the fluidity of the foam insulation material 5 . . Thereby, while maintaining or improving the heat insulating performance of the heat insulating box 1a, the wall surface thickness (heat insulation thickness) of the heat insulating box 1a is reduced, and the internal volume of the refrigerator 1 is enlarged and the energy-saving performance is improved.

In the heat-insulating box 1a constructed as described above, when it is desired to install the internal component mounting structure 10 in the range where the vacuum heat insulating material 6 is arranged, the sleeve 11 of the internal component mounting structure 10 is embedded in the foam insulation. The material fills the space 5 a (between the vacuum insulation material 6 and the inner box 3 ). Therefore, the thickness of the portion of the sleeve 11 according to the second embodiment protruding from the inner box 3 toward the outer box 2 (hereinafter referred to as the thickness on the heat insulating side) is set to the foam insulation filling space 5a. The material flow path width is 7 or less. Furthermore, as described above, in the heat insulating box 1a according to the second embodiment, in order to increase the thickness of the vacuum heat insulating material 6 having low thermal conductivity as much as possible, the foam heat insulating material flow path width 7 is suppressed so that the foam heat insulating material can ensure Minimum width of 5 for mobility. Therefore, in the heat insulating box 1a according to the second embodiment, when the internal component mounting structure 10 is to be installed in the range where the vacuum heat insulating material 6 is arranged, the vacuum heat insulating material 6 may come into contact with the sleeve 11. . Therefore, in Embodiment 2, the surface of the sleeve 11 that faces the vacuum heat insulating material 6 is formed in a planar shape.

As described above, in the refrigerator 1 configured in the second embodiment, the thickness of the heat insulation side of the sleeve 11 is narrowed to be equal to or less than the foam insulation flow path width 7 of the foam insulation filling space 5a, and the sleeve The surface of the cylinder 11 that faces the vacuum insulation material 6 is formed in a planar shape. Therefore, in the refrigerator 1 according to Embodiment 2, even when the vacuum heat insulating material 6 is in contact with the sleeve 11, it is possible to prevent the vacuum heat insulating material 6 from being damaged and the degree of vacuum of the vacuum heat insulating material 6 decrease, that is, to prevent the vacuum The heat insulating performance of the heat insulating material 6 is lowered, and the heat insulating performance of the heat insulating box 1a is lowered. Therefore, in the refrigerator 1 according to the second embodiment, the wall thickness (insulation thickness) of the heat insulating box 1a can be suppressed to a minimum, and compared with the conventional refrigerator having the same width as the refrigerator 1, it is possible to achieve a larger internal volume. expansion.
