The rear inner panel portion 15E is formed of a flat sheet member Sb made of synthetic resin as shown in Figs. 1 and 2 . The sheet member Sa and the sheet member Sb are produced by extrusion molding or roll forming without using a molding die having a special shape. It is also possible to use a flat sheet member of a commercially available product.

As shown in Fig. 4, between the outer box 14 and the inner box 15, there is a true Empty insulation panel 16. The vacuum heat insulating panel 16 is composed of a plate-shaped unit panel that is divided into a plurality of plates. That is, the vacuum heat insulating panel 16 is composed of a left unit panel 16A, a right unit panel 16B, an upper unit panel 16C shown in FIG. 10, a lower unit panel (not shown), and an inner unit panel 16E. Since each unit panel has the same basic structure, it will be described with respect to, for example, the left unit panel 16A.

As shown in FIGS. 8 and 9 , the left unit panel 16A is formed by accommodating the base material 19 in the covering body 20 and decompressing the inside thereof by vacuum evacuation. The base material 19 is formed into a plate shape by, for example, compressing and curing an aggregate of inorganic fibers such as glass fibers. The coating body 20 is formed, for example, as a metal layer containing an aluminum vapor-deposited layer or an aluminum foil layer in order to obtain a gas barrier property in which gas is hard to pass. Each unit panel is generally referred to as a vacuum insulation panel.

As shown in Fig. 5, the left heat insulating wall 9 is provided with a left unit panel 16A between the left outer plate portion 14A and the left inner plate portion 15A, and the three components are bonded by an adhesive to form a unit heat insulating layer. wall.

The front end portions of the outer casing 14 and the inner casing 15, that is, the front end portions of the left heat insulating wall 9 and the right heat insulating wall 10 are connected by the front end connecting member 21 as shown in Fig. 8. In other words, when viewed from the front end portion of the left heat insulating wall 9, the front end portions of the left outer panel portion 14A and the left inner panel portion 15A are coupled to each other by the distal end connecting member 21. The distal end connecting member 21 is made of synthetic resin and has heat insulating properties. In this case, since the front end portion of the left heat insulating wall 9 and the front end portion of the right heat insulating wall 10 are bilaterally symmetrical, the structure of the front end portion of the left heat insulating wall 9 will be described.

The front end portions of the left outer plate portion 14A and the left inner plate portion 15A are respectively from the left The front end portion of the unit panel 16A extends forward. The left outer plate portion 14A is bent toward the left inner plate portion 15A at the front end portion, and extends to the central portion in the thickness direction of the left unit panel 16A. The bent portion of the front end of the left outer plate portion 14A is referred to as a bent portion 14Aa. In this case, the bent portion 14Aa does not enter the inside of the heat insulating box 2, that is, the storage chamber side. That is, the bent portion 14Aa does not extend to the right side of the left inner plate portion 15A. Thereby, it is prevented that heat energy from the outside of the heat insulating box 2 is transmitted to the left outer plate portion 14A of the outer casing 14 and flows into the storage chamber.

A heat insulating material composed of, for example, a flexible tape 22 or the like is provided in the inner space portion formed by the front end portion of the left unit panel 16A, the inner surface of the front end portion of the left outer panel portion 14A, and the inner surface of the distal end connecting member 21. It is also possible to replace the flexible tape 22 with a foamed styrene.

The upper unit panel 16C is bonded to the upper inner plate portion 15C. A foamed polyurethane 24 is filled between the upper unit panel 16C and the upper outer panel portion 14C. As shown in FIG. 2, the upper outer plate portion 14C has an L-shaped portion 17a corresponding to the L-shaped portion 17 of the upper inner plate portion 15C. Thereby, the upper heat insulating wall 11 protrudes as a whole rear part. That is, the upper heat insulating wall 11 has a concave portion 11a at the rear portion. The space behind the concave portion 11a functions as the machine room 11b. In the machine room 11b, a compressor, a condenser, and the like (not shown) constituting a refrigeration cycle are provided. Mechanical 11b, as shown in Figure 3, is made up of a mechanical chamber housing 11c is closed.

As shown in Fig. 10, the dimension between the upper unit panel 16C and the upper outer panel portion 14C, that is, the thickness of the portion filled with the foamed polyurethane 24, is set to be smaller than the thickness of the upper unit panel 16C and smaller than the freezing The piping of the circulation such as the outer diameter of the straw. Thereby, the amount of the foamed polyurethane 24 used is reduced. In the case of pulling the piping of the refrigeration cycle in the tenth diagram, it is preferable that the piping passes through the corner portion of the upper left portion of the heat insulating box 2 in the front-rear direction. In this case, the corner portion is a space surrounded by the left end surface of the unit panel 16C, the upper end surface of the left unit panel 16A, the left end edge portion of the upper outer panel portion 14C, and the upper end edge portion of the left outer panel portion 14A.

As shown in Fig. 10, the left end portion of the upper outer plate portion 14C is separated from the upper surface of the upper unit panel 16C and connected to the left outer plate portion 14A. Although not illustrated in detail, the right end portion of the upper outer panel portion 14C is also separated from the upper surface of the upper unit panel 16C and connected to the right outer panel portion 14B. The upper inner plate portion 15C has a coupling portion 15C1. The connecting portion 15C1 is also provided on the left and right edges of the upper inner plate portion 15C as shown in Fig. 6 . As shown in Fig. 10, the connecting portion 15C1 connects the upper inner plate portion 15C and the left inner plate portion 15A. In this case, the front end portion of the coupling portion 15C1 is coupled to the left inner panel portion 15A by a coupling member (not shown).

Here, the connection portion 15C1 on the left side will be described. The connection portion on the right side has the same structure as the connection portion 15C1 on the left side except for the left-right symmetrical shape. As shown in Fig. 10, the connecting portion 15C1 has a rib 15C2. The rib 15C2 protrudes upward in the inner side of the front end portion of the connecting portion 15C1, that is, on the side of the foamed urethane 24, and substantially in parallel with the left inner plate portion 15A. In the rib For example, a soft tape 23 as a heat insulating material leakage preventing member is inserted between the portion 15C2 and the left inner plate portion 15A. The flexible tape 23 is for preventing leakage of the foamed polyurethane 24 when the foamed polyurethane 24 is filled.

The lower heat insulating wall 12 has a lower unit panel (not shown) between the lower outer plate portion 14D and the lower inner plate portion 15D. The lower unit panel is bonded to the lower outer plate portion 14D and the lower inner plate portion 15D, respectively. Thereby, the unit heat insulating wall is formed. The lower heat insulating wall 12 may be formed by bonding the lower inner plate portion 15D to the lower unit panel and filling the lower unit panel and the lower outer plate portion 14D with foamed polyurethane to be cured. The lower heat insulating wall 12 and the lowermost portion of the drain receiving portion 18 communicate with the outside of the heat insulating box 2.

The inner heat insulating wall 13 is also provided with an inner unit panel 16E between the rear outer panel portion 14E and the rear inner panel portion 15E, and the three are formed of an adhesive. In this case, it is also possible to increase the structure which is suitably filled with foamed polyurethane and cured.

In the upper inner plate portion 15C and the lower inner plate portion 15D, the integrally molded members Ia and Ib made of a hydrocarbon resin are surface-processed into a rough surface by the surface of the bonding surface of the unit panel, thereby enhancing the unit panel. Adhesiveness. In the left inner plate portion 15A, the right inner plate portion 15B, and the rear inner plate portion 15E, since the sheet members Sa and Sb are made of ABS resin, the adhesion to the unit panel is excellent.

Here, the connection between the left heat insulating wall 9 and the inner heat insulating wall 13 will be described with reference to FIGS. 9 and 11 to 14 . The left heat insulating wall 9 and the inner heat insulating wall 13 are connected by a sheet member connecting plate 25, a fixing member 26, and the like. In this case, the sheet member connecting plate 25 functions as a connecting member for the sheet member, and the fixing member 26 functions as the first protruding portion.

When the beam member 52 is assembled, the front partition plate 52a and the reinforcing plate 52b are first integrated by the screws 63. Then, the left end portions of the front partition plate 52a and the reinforcing plate 52b are inserted into the back side of the front surface portion 14A1 of the left outer plate portion 14A. Then, the screw 62 is screwed into the screw hole of the reinforcing plate 52b through the folded portion 14A2 of the left outer plate portion 14A and the hole portion of the end portion of the front partition plate 52a. Thereby, the front partitioning plate 52a is clamped between the reinforcing plate 52b and the folded-back portion 14A2 to be fixed.

On the rear side of the front partition plate 52a, a rear partition casing 52c in which the heat insulating material 52d is housed is attached. The left heat insulating wall 9 and the right heat insulating wall 10 are fixed by connecting the left and right edge portions of the front opening of the heat insulating box 2 by the front partitioning plate 52a. Thereby, it is possible to prevent the front opening of the heat insulating box 2 from opening or contracting, and it is possible to hold the storage compartment in a rectangular parallelepiped shape.

If the strength of the front partitioning plate 52a is sufficient, the reinforcing plate 52b may not be provided.

The back partition casing 52c has a mounting portion that protrudes downward, although not shown, and the mounting portion is screwed by a fixing member similar to the fixing member 26.

According to the first embodiment described above, the left inner plate portion 15A and the right inner plate portion 15B of the inner box 15 are formed by a flat sheet member Sa. The rear inner panel portion 15E is constituted by a flat sheet member Sb. Thereby, the left inner plate portion 15A, the right inner plate portion 15B, and the rear inner plate portion 15E do not require a molding die at the time of manufacture, so that the manufacturing is very simple, and as a result, the manufacturing cost is also reduced.

The other portions of the inner box 15 are the upper inner plate portion 15C and the lower inner plate portion 15D, and are integrally formed by a mold. However, compared with the conventional structure in which the entire inner casing 15 is integrally molded by a large mold, it is easier to manufacture and the manufacturing cost can be further reduced. It can also help to reduce the cost of the refrigerator 1.

In this case, at least one of the left inner plate portion 15A, the right inner plate portion 15B, the upper inner plate portion 15C, the lower inner plate portion 15D, and the rear inner plate portion 15E may be formed of a sheet member.

In this embodiment, the inner box 15 is configured by combining the left inner panel portion 15A, the right inner panel portion 15B, the upper inner panel portion 15C, the lower inner panel portion 15D, and the rear inner panel portion 15E. In this case, the two adjacent inner plate portions, that is, the left inner plate portion 15A, the rear inner plate portion 15E, and the right inner plate portion 15B are each divided by different sheet members. Between the adjacent inner plate portions, that is, between the left inner plate portion 15A and the rear inner plate portion 15E, and between the right inner plate portion 15B and the rear inner plate portion 15E, adjacent inner plates are respectively provided The sheet member connecting plates 25 and 25 which are the connecting members for the sheet members are connected to each other.

Thereby, the left inner plate portion 15A and the rear inner plate portion 15E, and the right inner plate portion 15B and the rear inner plate portion 15E which are formed of the sheet member are simply used by the sheet member connecting plates 25 and 25 using other components. Link, you can reach Simplification of assembly.

In the first embodiment, the heat insulating box 2 is divided into a plurality of unit heat insulating walls, that is, the left heat insulating wall 9, the right heat insulating wall 10, the upper heat insulating wall 11, and the lower heat insulating wall 12 The inner heat insulating wall 13 is connected to each other. In the conventional structure, the heat insulating box is constructed by assembling an undivided outer box and an inner box, so that the assembly is large and the operation is also large. However, in the present embodiment, the heat insulating box 2 is formed by assembling the heat insulating walls 9 to 13 having the vacuum heat insulating panel, so that the assembly is simple, the work is not too large, and the work can be easily performed.

According to the first embodiment, the front end portion 15 is connected to the front end portion of the outer casing 14 by the distal end connecting member 21 at the distal end portion of the portion formed of the sheet member. Therefore, even if the inner casing 15 is a portion formed of a sheet member, it can be easily assembled or joined by a member different from the outer casing 14, that is, the distal end connecting member 21.

In the first embodiment, the inner box 15 has the L-shaped portion 17 in the upper heat insulating wall 11 and the drain receiving portion 18 in the lower heat insulating wall 12. The L-shaped portion 17 is integrally formed in the upper inner plate portion 15C, and the drain receiving portion 18 is integrally formed in the lower inner plate portion 15D. Thereby, the L-shaped portion 17 or the drain receiving portion 18 can be easily formed by being integrally molded with respect to the inner plate portions 15C and 15D even in a complicated shape.

In the first embodiment, the inner box 15 has a first protruding portion that is formed separately from the sheet members Sa and Sb and protrudes toward the inside of the refrigerator, that is, the fixing member 26. The fixing member 26 is directly bonded to the left unit panel 16A at a stage before assembling the left heat insulating wall 9, for example. Sheet member The left and right inner plate portions 15A and 15B formed by Sa and the rear inner plate portion 15E formed of the sheet member Sb are formed with a hole portion 15u. The fixing member 26 is provided to pass through the hole portion 15u.

Thereby, by inserting the fixing member 26 into the hole portion 15u, the position of the fixing member 26 can be determined with respect to the inner box 15, that is, the sheet members Sa, Sb. The partition wall supports 35, 36 and the rear casing mount 37 are also formed in the same mounting structure as the fixture 26. Then, the partition wall supports 35 and 36 and the rear outer casing mount 37 are positioned in the same manner as the stator 26.

The fixing member 26 may be inserted and adhered from the back side of the sheet members Sa and Sb with respect to the hole portion 15u at a stage before the left heat insulating wall 9 is assembled. Thereby, the fixing member 26 and the sheet member can be handled in an integrated state. Therefore, when the unit heat insulating wall is assembled, the unit panel and the integrated product of the fixing member 26 and the sheet members Sa and Sb can be bonded to each other, and the assembly workability is excellent.

As shown in Fig. 13, the mounting surface of the fixing member 26 of the unit panel 16A can also be recessed. Thereby, the fastener 26 can be attached without bending the sheet member Sa.

In the case where the unit panel 16A is inflated, since the inner panel portion 15A is constituted by the sheet member Sa, the inner panel portion 15A is not broken and is completed to a slight degree of deformation.

The fixing member 26, the panel supporting member 30, the rail mounting members 33, 34, and the partition wall supporting members 35, 36 can also be commonly used in the heat insulating box of the refrigerator of different models.

According to the first embodiment, the fixing member 26 is directly bonded to the left unit panel 16A, the right unit panel 16B, and the inner unit panel 16E. Therefore, each of the unit panels 16A, 16B, and 16E can be easily inserted into the hole portions 15u of the corresponding inner plate portions 15A, 15B, and 15E, respectively, for the respective inner plate portions 15A, 15B, and 15E. Decide on the location. In this case, since the fixing member 26 is made of ABS resin having excellent adhesion, the adhesion strength between the lifting fixture 26 and each of the unit panels 16A, 16B, and 16E can be achieved.

The partition wall supports 35, 36 and the rear outer casing mount 37 are also formed in the same mounting structure as the fixture 26. Thus, the partition wall supports 35, 36 and the rear outer casing mount 37 also contribute to the alignment of the inner panel portions with the unit panels.

The fixing member 26 may be bonded to each of the unit panels 16A, 16B, and 16E via other members.

In the first embodiment described above, the fixing member 26 has a flange portion 26a larger than the hole portion 15u. The flange portion 26a is sandwiched between the sheet members Sa, Sb, and a unit panel corresponding thereto. Thereby, the fixing member 26 can be prevented from falling off from the hole portion 15u by the flange portion 26a. The flange portion 26a can be adhered to the corresponding inner plate portion to help increase the strength of the corresponding inner plate portion. The flange portion 26a is formed in a sheet shape. Therefore, the fixing member 26 can be inserted between the inner panel portion and the unit panel by passing the flange portion 26a from the inside of the refrigerator through the hole portion 15u.

In the first embodiment, the inner box 15 has the panel supporting portion 30b as the second protruding portion. a shed support 30 having a shed support 30b, and The sheet member Sa constituting the left and right inner plate portions 15A and 15B is made of a different component and protrudes toward the inside of the refrigerator. A screw insertion hole portion 31 is formed in the sheet member Sa. The slab support member 30 is fixed to the surface side of the sheet member Sa from the back side of the sheet member Sa, that is, the side opposite to the inside of the refrigerator, with respect to the screw insertion hole portion 31 by the head screw 32 that passes toward the inside of the refrigerator. It is the face inside the refrigerator.

Thereby, the panel support member 30 can be attached to the sheet member Sa by the fastening member, that is, the head screw 32. In this case, a rivet can also be used as the fastening member. The rivet, for example, penetrates the sheet member Sa and the panel support member 30, and the panel support member 30 is fixed to the sheet member Sa by caulking both end portions thereof.

In the first embodiment, the peripheral edge portion 31a of the screw insertion hole portion 31 is separated from the vacuum heat insulating panels, that is, the right and left unit panels 16A and 16B. In other words, the screw head portion 32a of the head screw 32 does not protrude from the peripheral edge portion 31a of the screw insertion hole portion 31 toward the left and right unit panels 16A and 16B, respectively.

Thereby, the screw head portion 32a does not protrude toward the rear surfaces of the inner plate portions 15A, 15B, that is, the unit panels 16A, 16B. Therefore, the screw head 32a is prevented from coming into contact with the unit panels 16A, 16B. Therefore, it is possible to prevent the covering body 20 of each unit panel 16A, 16B from being damaged due to the contact of the screw head portion 32a. Further, the screw head portion 32a does not interfere with the adhesion between the left unit panel 16A and the left inner panel portion 15A, and the adhesion between the right unit panel 16B and the right inner panel portion 15B.

Further, the slab support member 30 has a peripheral portion of the opening of the screw hole portion 30c. A counterbore 30d having a tapered hole shape is formed. When the screw head 32 is screwed into the screw hole portion 30c, the peripheral edge portion 31a of the screw insertion hole portion 31 of the sheet member Sa is deformed toward the counterbore 30d side, and is naturally separated from the right and left unit panels 16A, 16B. . Thereby, the sheet member Sa does not need to specifically form a concave portion for accommodating the screw head portion 32a.

The rail mounting members 33 and 34 are also formed in the same mounting structure as the panel supporting member 30. Thus, the same effect as the panel support member 30 can be achieved with respect to the rail mounting members 33, 34 portions. Further, the same effects as those of the panel support member 30 can be achieved for the panel support member 30 and the rail attachment members 33 and 34 (not shown) provided on the right heat insulating wall 10.
