The second sealing member 102 is configured similarly to the second sealing member 72 provided on the side of the fixture 511.

Further, as shown in Fig. 22, a portion where the right divided heat insulating wall 313 and the back divided heat insulating wall 315 are in contact with each other is provided, and a third sealing member 103 is provided. The third sealing member 103 is configured in the same manner as the third sealing member 73 provided in the portion where the right divided heat insulating wall 313 and the back divided heat insulating wall 315 are in contact with each other.

In this manner, the fixture 512 is constituted by the fixing cover 81 and the reinforcing member 82 holding the corner heat insulating member 83. The corner heat insulating member 83 accommodates the pipe 53 in the accommodating portion 98. The fixing cover 81 passes the through hole 84 in a state in which the end portion in the width direction overlaps the end portion in the width direction of the reinforcing member 82. The screw hole 57 of the reinforcing member 82 is screwed by the screw 57 of the through hole 84. In this way, the fixing cover 81 is fixed to the reinforcing member 82. Then, the fixing cover 81 is fixed to the reinforcing member 82, and the corner heat insulating member 83 and the pipe 53 are also fixed to the inside of the fixture 51.

In this case, the fixed cover 81, the reinforcing member 82, the corner heat insulating member 83, and the pipe 53 form an integrated structure. Then, the second partition The right rear end portion of the member 38 enters between the upper fixing cover 811 and the lower fixing cover 812, and is in contact with the connecting portion between the upper corner insulating member 831 and the lower corner insulating member 832. As a result, the divided portion of the fixture 512 is covered by the right rear end portion of the second partition member 38.

Further, the right divided heat insulating wall 313 and the back divided heat insulating wall 315 face the reinforcing member 82 via the second sealing member 102. In this manner, the adjacent right divided heat insulating wall 313 and the back divided heat insulating wall 315 are connected and fixed by the fixture 512, and the right divided heat insulating wall 313 and the back side divided heat insulating wall 315 form an angle. It is maintained at 90° corresponding to the right angle portion of the reinforcing member 82. In other words, the reinforcing member 82 can function as an angle holding portion that "holds the angle between the adjacent right divided heat insulating wall 313 and the back divided heat insulating wall 315 at 90 degrees".

The pipe 53 may also pass between the right end edge portion of the second partition member 38 and the right inner plate 24 as shown in Fig. 32. In this case, a heat insulating member 105 for partitions is provided between the surface partition portion 45 of the second partition member 38 and the right inner panel 24 of the inner box 14 inside the inner box 14. The heat insulating member 105 for partitions is composed of, for example, a foamed styrene polymer, and functions as a heat insulating member. The partition portion heat insulating member 105 is formed in a quadrangular prism shape that is elongated in the front-rear direction along the right end edge portion of the second partition member 38. The partition heat insulating member 105 has a recess 106. The concave portion 106 is formed in a concave shape in which the opening portion heat insulating member 105 has an opening on the right inner plate 24 side. A part of the pipe 53 is provided inside the recess 106 of the partition heat insulating member 105. In this case, although not shown in detail in the drawing, the piping 53 may be arranged in the following manner.

For example, the two pipes 53 are respectively inserted into the accommodating portion 98 of the upper corner heat insulating member 831 from the upper end portion of the fixture 512 and extend downward and downward. After that, the piping 53 projects from the connection portion between the upper corner heat insulating member 831 and the lower corner heat insulating member 832 toward the front side of the housing portion 98. Next, the pipes 53 pass through the inside of the recess 106 of the heat insulating member 105 for partitions, and extend forward along the right end edge of the second partition member 38. After that, the pipes 53 are respectively folded back toward the rear side at the front end portion of the second partition member 38, and are again extended rearward along the right end edge portion of the second partition member 38 inside the recess portion 106. Then, the piping 53 enters the inside of the accommodating portion 98 of the lower corner heat insulating member 832 from the connection portion between the upper corner heat insulating member 831 and the lower corner heat insulating member 832. After that, the pipes 53 are extended from the openings 86 and 88, and are connected to the refrigerating cooler and the refrigerating cooler, respectively.

Although not shown in the drawing, the inside of the inner box 14 is provided with a heat insulating member 105 for the structure and partition between the surface partition portion 45 of the second partition member 38 and the left inner panel 25 of the inner box 14. Similarly to the above-described piping 53, the same member may be disposed along the left end edge of the second partition member 38.

The assembly procedure of the heat insulating box 12 of the refrigerator of this embodiment will be described with reference to Figs. 1 and 33.

First, the divided heat insulating wall 31 and the fixture 51 shown in Fig. 1 are produced separately. Next, as shown in Fig. 33, the fixture 511 is attached to one of the adjacent two divided heat insulating walls 31 by screws 57, such as the left divided heat insulating wall 314. Next, the back side divided heat insulating wall 315 is attached to The left divided heat insulating wall 314 and the fixture 511 form an integrated assembly. In this case, the adjacent divided heat insulating walls 31 are connected and fixed to the left divided heat insulating wall 314 and the back divided heat insulating wall 315, and the corner portions of the inner right side of the inner box 14 are formed. In this case, the angle of the adjacent wall formed by the left divided heat insulating wall 314 and the back divided heat insulating wall 315 is maintained at 90° in accordance with the right angle portion of the reinforcing member 55. The other corner portion of the inner box 14 is also formed by fixing and dividing the heat insulating wall 31 and the fixture 51. In this way, the inner box 14 "the angle of the adjacent divided heat insulating wall 31 is 90" is formed, and the cubic heat insulating box 12 is formed.

As described above, the fixture 51 defines the angle of the adjacent divided insulating wall 31 to a specific value, such as 90°. The angle of the adjacent divided heat insulating walls 31 is not limited to 90°. In this case, the angle of the adjacent divided heat insulating walls 31 is adjusted to approach 90°, and the heat insulating box 12 is provided. Each corner portion can be formed to approach 90 degrees. In other words, the angle specified by the fixture 51 need not be quite rigorous and can be tolerated within the scope of the general error produced by the manufacturing process.

The first partition member 37 and the second partition member 38 are attached to specific positions with respect to the heat insulating box 12 assembled as described above. In this way, the inside of the heat insulating box 12 is formed with a refrigerating chamber 39, a fruit and vegetable chamber 40, an ice making chamber 41, a first freezing chamber 42, and a second freezing chamber 43. Next, the front end portions of the right divided heat insulating wall 313 and the left divided heat insulating wall 314 are connected and fixed by the first partition member 37 and the second partition member 38.

According to the above configuration, the following effects can be achieved.

The heat insulating box 12 of the refrigerator 11 is a combination of a plurality of divided heat insulating walls 31 divided into a plurality of pieces, and is formed by connecting and fixing two adjacent heat insulating walls 31 by fixing means 51. According to this, the assembly work of the refrigerator 11 becomes easier than the conventional structure in which the heat insulating member is provided in the three-dimensional inner case in advance.

The reinforcing members 55 and 82 of the fixture 51 can function as an angle holding portion that maintains the angle of the adjacent divided heat insulating walls 31 at 90 degrees. Thereby, the inner box 14 can be formed into a cube. Further, since the heat insulating box 12 has a structure in which the corner portion of the inner box 14 can be held at 90 degrees, the assembly of the divided heat insulating walls 31 becomes easy.

The fixture 51 is fixed at a position facing the two adjacent heat insulating members 15. For this reason, the heat insulating member 15 can be fixed with the fixture 51 as a reference. In this way, it is easy to maintain the angle of the adjacent divided heat insulating walls 31 at 90°.

The right divided heat insulating wall 313 and the left divided heat insulating wall 314 are connected and fixed by the first partition member 37 and the second partition member 38 in the vicinity of the center in the vertical direction. Therefore, the front end portion of the right divided heat insulating wall 313 and the front end portion of the left divided heat insulating wall 314 can be stably fixed. As a result, it is possible to suppress the front opening portion of the inner case 14 from opening in the left-right direction. Moreover, the distortion of the inner box 14 can be suppressed, and the inner box 14 and the heat insulating box 12 can be held in a cubic shape.

The electric wires 52 and the pipes 53 provided at the corners of the inner box 14 are covered by the fixture 51. For this reason, it is possible to prevent the food in the storage compartment from coming into contact with the electric wire 52 or the piping 53 as much as possible. Not only that, due to the wires 52 Since the piping 53 is not seen by the user, the appearance inside the storage compartment can be improved.

Corner insulating members 56 and 83 are provided at the corners of the inner box 14. In this way, the heat insulation effect at the corner portion can be improved. Further, since the corner heat insulating members 56 and 83 are covered by the fixture 51, the appearance of the inside of the storage compartment can be improved as described above.

The corner heat insulating members 56 and 83 are disposed so as to cover the abutting portions of the adjacent divided heat insulating walls 31. In other words, the heat insulating performance is likely to become a contact portion of the two lower divided heat insulating walls 31, and the heat insulating properties can be enhanced by the corner heat insulating members 56 and 83. In this way, the thermal insulation performance of the heat insulating box 12 as a whole can be improved.

The fixture 51 is formed in a tubular shape, and an electric wire 52 or a pipe 53 is housed inside the cylindrical shape; and the corner heat insulating members 56 and 83 are housed. As a result, the electric wire 52, the piping 53, and the corner heat insulating members 56 and 83 are not visible to the user, so that the appearance of the interior of the storage compartment can be further improved.

The fixture 51 has reinforcing members 55 and 82 that are formed in an L-shaped cross section. As a result, the fixture 51 can increase the strength of deformation such as twisting or bending. In addition, since the fixture 51 has a structure in which the fixing members 55 and 81 are provided in the L-shaped cross-section reinforcing members 55 and 82, the tubular shape can be easily formed.

Since the electric wires 52 and the pipes 53 are held by the accommodating portions 67 and 98 of the corner heat insulating members 56 and 83, it is possible to suppress the electric wires 52 and the pipes 53 from being displaced from a specific position.

The fixing cover 54 of the fixture 511 has openings 59, 60. Gateway to solid The electric wire 52 of the stator 511 can be guided to the storage compartment side through the openings 59 and 60. As a result, the electric wire 52 can protrude from the opening portions 59, 60 toward the storage compartment side, and is connected to the electric wire located outside the fixture 511, that is, on the storage compartment side. In particular, the electric wire 52 has a connecting portion 68 for connection with other electric wires at an end projecting from the opening portions 59, 60 of the fixture 511. Thereby, the electric wire 52 can be easily connected to other electric wires on the outside of the fixture 511.

The fixing cover 81 of the fixture 512 has openings 86, 88. The piping 53 leading to the fixture 512 can be guided to the storage compartment side through the openings 86 and 88. In this way, the pipe 53 can protrude from the opening portions 86, 88 toward the storage chamber side, and is connected to the pipe located on the storage compartment side. In particular, the pipe 53 has a welded portion 99 for welding to other pipes at the end portion extending from the opening portions 86, 88 of the fixture 512. Thereby, the pipe 53 can be easily welded to the other pipes on the outer side of the fixture 512 to form a connection.

Further, the electric wire 52 is integrated in the fixture 511, and the pipe 53 is integrated in the fixture 512. In this case, when the split heat insulating wall 31 is connected and fixed by the fixture 51, the electric wire 52 and the pipe 53 are also provided in a specific corner portion of the divided heat insulating wall 31. In this way, the assembly work of the electric wires 52 and the pipes 53 can be simplified.

The electric wire 52 is provided at a corner portion inside the left side of the inner box 14 and covered by the fixture 511. The pipe 53 is provided at a corner portion inside the right side of the inner box 14 and is covered by the fixture 512. In this way, it is possible to reduce the situation in which the electric wire 52 is frozen by the piping 53.

Further, in "a part of the pipe 53, along the second partition member 38 In the case of the right edge portion arrangement, the pipe 53 can be increased without increasing the fixture 51. In the case where the pipe 53 is a suction pipe, the storage space of the storage compartment can be sufficiently ensured, and the length of the pipe 53 can be ensured to improve the efficiency of heat exchange.

Between the fixed covers 54, 81 and the reinforcing members 55, 82, first sealing members 71, 101 are provided, respectively. The first sealing members 71, 101 can suppress cold airflow into the interior of the fixtures 511, 512. As a result, it is possible to suppress the occurrence of condensation on the inside of the fixture 51, such as the electric wire 52.

Between the divided heat insulating wall 31 and the fixture 51, second sealing members 72, 102 are provided. The second sealing members 72, 102 seal between the reinforcing members 55, 82 and the divided heat insulating walls 31, respectively. In other words, the second sealing members 72, 102 can improve the airtightness between the reinforcing members 55, 82 and the divided heat insulating walls 31, respectively. In this way, air can be prevented from entering the inside of the heat insulating box 12 through the abutting portion of the adjacent two divided heat insulating walls 31, that is, the storage chamber. Therefore, it is possible to reduce the leakage of the cold air in the storage compartment to the outside of the heat insulating box 12, and to reduce the flow of the heater outside the heat insulating box 12 into the storage compartment.

The abutting portions of the adjacent two divided heat insulating walls 31, for example, between the right divided heat insulating wall 313 and the back divided heat insulating wall 315, and the left divided heat insulating wall 314 and the back divided heat insulating wall 315 The third sealing members 73, 103 are provided. Thereby, the inside and the outside of the heat insulating box 12 can be sufficiently thermally insulated, and thus the inside of the heat insulating box 12 can be efficiently cooled.

The fixture 51 is divided into a plurality of pieces in a direction extending along the corner portion In the case of the embodiment, it is divided into two. Therefore, the operation of the fixture 51 becomes easy. Further, a second partition member 38 is disposed at a divided portion of the fixture 51. As a result, it is possible to suppress the cold air in the storage chamber from entering the inside of the fixture 51 from the divided portion of the second partition member 38.

The heat insulating wall 31 is divided by sandwiching the heat insulating member 15 between the outer plates 16 to 20 and the inner plates 22 to 26. The heat insulating member 15 is composed of a vacuum heat insulating panel which is thin and has excellent heat insulating properties. Therefore, dividing the heat insulating wall 31 can obtain high heat insulating properties of the vacuum heat insulating panel and reduce the thickness thereof. Therefore, compared with the conventional technique using a heat insulating material such as urethane, as long as the outer shape of the heat insulating box 12 is the same, the internal volume can be greatly increased.

Further, according to the above configuration, since the electric wires 52 and the pipes 53 are provided at the corners deep inside the inner box 14, it is less likely to cause interference when the food is stored.

An upper side separation portion 211 that is connected to the machine room 21 is provided right above the fixture 51. Further, a lower side separation portion 213 that is connected to the component storage chamber 212 is provided directly below the fixture 51. Therefore, the electric wire 52 and the pipe 53 in the fixture 51 can be easily guided to the machine room 21 and the component storage chamber 212 by the upper and lower separating portions 211 and 213. In this way, the electric wires 52 and the pipes 53 can be easily connected to other electric wires and pipes in the machine room 21 and the component storage chamber 212.

(Second embodiment)

Next, a second embodiment will be described with reference to Fig. 34. The structure of the corner portion of the left inner side of the inner box 14 described in the second embodiment is also Can be applied to other corners.

The fixture 111 of the second embodiment does not have a reinforcing member. The fixture 111 is a plate member having a shape almost the same as that of the fixing cover 54 of the first embodiment, and is formed to extend along a corner portion of the inner box 14. In this embodiment, the two adjacent divided heat insulating walls 31 are referred to as the left side divided heat insulating wall 314 and the back side divided heat insulating wall 315, which are not shown in the drawing. The screw is fixed to the fixture 111. In other words, the adjacent two divided heat insulating walls 31 are connected and fixed by the fixture 111.

The fixture 111 has two extensions 112, 113. The extending portions 112 and 113 are respectively provided in the short side direction of the fixture 111, that is, both end portions in the width direction. The extending portions 112 and 113 face the inner plates 22 to 26 which are close to each other, and in the case shown in the drawing, the left inner plate 25 of the left divided heat insulating wall 314 and the back inner plate 26 of the rear divided heat insulating wall 315 are Form an extension. In other words, the extension portion 112 extends toward the front side of the heat insulating box 12 along the left inner panel 25. The extension portion 113 extends along the back inner panel 26 toward the right side of the heat insulating box 12.

In this case, the extending portion 112 faces the left inner panel 25 side and divides the surface extending toward the back side of the heat insulating wall 315 side, and extends the side of the extending portion 113 facing the back inner panel 26 side and dividing toward the left side heat insulating wall 314 side. Face" formed an orthogonal. Therefore, once the adjacent left divided heat insulating wall 314 and the back side divided heat insulating wall 315 are joined and fixed by the fixture 111, the adjacent wall formed by the left side divided heat insulating wall 314 and the back side divided heat insulating wall 315 is formed. The angle will be limited to 90°. In this case, the extending portions 112 and 113 of the fixture 111 can function as an angle holding portion.

A fourth sealing member 114 is provided between the extending portions 112, 113 and the inner plates 25, 26 which are adjacent to each other. The fourth sealing member 114 is configured identically to the second sealing members 72, 112.

Further, in the case where the triangular columnar space formed by the corner portion of the inner box 14 and the fixture 111 is formed by the left inner panel 25 and the back inner panel 26 and the fixture 111, the level is horizontal. The cross section of the direction has a triangular shape and is provided with a second corner heat insulating member 115. In this case, the fixture 111 is covered by the second corner heat insulating member 115. The second corner heat insulating member 115 is composed of a heat insulating member such as a foamed styrene polymer, and is formed in a triangular column shape.

The second corner heat insulating member 115 has a housing portion 116. The accommodating portion 116 is formed by causing the second corner heat insulating member 115 to be recessed from the left inner panel 25 side. The accommodating portion 116 extends in the longitudinal direction of the second corner heat insulating member 115. The electric wire 52 is provided inside the accommodating portion 116 and held by the accommodating portion 116. In this case, the accommodating portion 116 can function as a holding portion that holds the electric wire 52.

According to the above configuration, the adjacent two divided heat insulating walls 31 can be connected and fixed by using the fixture 111 having no structure of the reinforcing member.

The fixture 111 has extension portions 112, 113 that are orthogonal to each other. Therefore, the angle of the adjacent inner plates of the inner box 14 can be maintained at 90 degrees. In this way, the inner box 14, that is, the heat insulating box 12, can be formed into a cube.

Between the extending portions 112, 113 and the divided heat insulating wall 31, there is a fourth Sealing member 114. Therefore, it is possible to suppress the cold air in the storage chamber from leaking to the outside of the heat insulating box 12, and it is possible to suppress the warm air outside the heat insulating box 12 from flowing into the storage chamber.

The electric wire 52 is housed in the accommodating portion 116 of the second corner heat insulating member 115. Therefore, it is possible to prevent the electric wire 52 from being displaced from a predetermined position as much as possible.

(Third embodiment)

Next, a third embodiment will be described with reference to Fig. 35. The structure of the corner portion of the inner right side of the inner box 14 described in the third embodiment can also be applied to other corner portions.

In the third embodiment, as shown in Fig. 35, the heat insulating member 120 is composed of the first heat insulating member 121 and the second heat insulating member 122. The first heat insulating member 121 is composed of a vacuum heat insulating panel. The first heat insulating member 121 is disposed on the outer surface side of the inner plates 22 to 26 of the inner box 14. The second heat insulating member 122 is a member having a higher thermal conductivity than the first heat insulating member 121, in other words, a member having a lower heat insulating property than the first heat insulating member 121. For example, the second heat insulating member 122 is a flexible tape or a foamed heat insulating material such as urethane.

The second heat insulating member 122 is positioned between the outer box 13 and the inner box 14 and covers the periphery of the first heat insulating member 121. In this case, the second heat insulating member 122 is disposed in a space in which the heat insulating member 120 is housed, and a space other than the first heat insulating member 121 is disposed. That is, the second heat insulating member 122 is provided at a corner portion of the heat insulating box 12, that is, a position corresponding to the third sealing member 73 in the first embodiment. In this case, the first heat insulating member Preferably, 121 is 50% or more of the total volume of the "space in which the heat insulating member 120 is housed", and more preferably 80% or more.

In other words, the volume of the second heat insulating member 122 is set to be smaller than the volume of the first heat insulating member 121. Further, as shown in Fig. 35, if the thickness of the first heat insulating member 121 is defined as T ₁ , the thickness of the second heat insulating member 122 is defined as T ₂ , and the outer diameter of the pipe 53 is defined as T _{3 .} Then, it is set to T ₁ > T ₃ > T ₂ . The plate thickness referred to herein means the thickness of the outer casing 13 and the inner casing 14 in the cross-sectional direction in the horizontal cross section of the heat insulating wall 31. That is, the thickness of the second heat insulating member 122 means that the first heat insulating member 121 and the inner surface of the outer case 13 facing the first heat insulating member 121, such as the right outer plate 18 in FIG. The distance between them. Further, in the case of the foamed heat insulating material, it means the thickness after curing.

According to the above configuration, the refrigerator using the two kinds of heat insulating members of the first heat insulating member 121 and the second heat insulating member 122 can be obtained. Even in this case, the electric wire 52 and the pipe 53 are provided in the inner corner portion of the accommodating space of the heat insulating box 12. Next, the increase in the heat insulating effect is superior to the volume of the first heat insulating member 121 of the second heat insulating member 122. Thereby, the wall of the heat insulating box 12 can be made thinner and high heat insulating performance can be obtained, and the storage space can be sufficiently ensured.

In other words, if the space for accommodating the pipe 53 is secured between the first heat insulating member 121 and the outer casing 13 in the interior of the heat insulating wall 31, it is necessary to make the plate of the first heat insulating member 121. The thickness T _{1 is} thinned or the thickness T _{2 of the} second heat insulating member 122 is increased. The former method reduces the heat insulating performance of the heat insulating box 12, and the latter method increases the thickness of the divided heat insulating wall 31 to reduce the accommodating space. Therefore, in the present embodiment, the pipe 53 is housed in the rear of the storage compartment, and in this case, the compartment is housed in a corner portion on the right side inside the inner casing 14. As a result, since the heat insulating box 12 does not need to lower the thickness T _{1 of the} first heat insulating member 121, good heat insulating performance can be obtained. Further, since the heat insulating box 12 does not need to increase the thickness T _{2 of the} second heat insulating member 122, it is not necessary to increase the thickness of the divided heat insulating wall 31, and a sufficient housing space can be secured.

In other words, as in the present embodiment, when the outer diameter T _{3 of the} pipe 53 is larger than the plate thickness T ₂ of the second heat insulating member 122, the pipe 53 cannot be accommodated inside the divided heat insulating wall 31, particularly the first partition. The heat member 121 is between the outer casing 13. In this case, the pipe 53 is housed in the accommodating space, such as the inside of the storage compartment, and the thickness T _{1 of the} first heat insulating member 121 can be increased to be larger than the thickness T _{2 of the} second heat insulating member 122, and can be formed. The heat insulating box 12 has a heat insulating structure.

As for the first heat insulating member 121, good heat insulating properties can be obtained by using a vacuum heat insulating panel. Further, even if the vacuum heat insulating panel having a small thickness has a good heat insulating effect, the wall of the heat insulating box 12 can be made thin, and the storage space can be sufficiently ensured.

The second heat insulating member 122 can be embedded in the first heat insulating member 121, the first heat insulating member 121 and the outside by using a foamed heat insulating material, in this case, urethane. Between the boxes 13, between the first heat insulating member 121 and the inner box 14. As a result, the heat insulating effect of the entire heat insulating box 12 can be improved.

In the above description, the outer diameter of the pipe 53 is defined as T ₃ , but the wire 52 located at the corner of the inner left side of the inner box 14 may be defined as the outer diameter of the bundle of the plurality of wires. For T ₃ .

(Other embodiments)

Although the structure in which the electric wire 52 and the piping 53 are provided in the corner portion of the inner box is formed, the present invention is not limited thereto, and it is also possible to provide a hose (or a telescopic tube) in addition to the electric wire 52 and the pipe 53. A part such as a cover 51 is used to cover the construction of the part.

The fixture 51 is formed to be divided into a plurality of structures in the longitudinal direction. However, for example, when the fixture 51 is provided in a corner portion having no partition member or a corner portion having a short length, the fixture 51 does not have to be divided into a plurality of pieces in the longitudinal direction.

The fixture 51 of the first embodiment may have the extending portions 112 and 113 of the fixture 111 in the second embodiment. In this case, it is only necessary to provide the fourth sealing member 114 between the fixture 51 and the inner box 14 instead of the second sealing member 72.

A part of the electric wire 52 and a part of the pipe 53 may be disposed between the second partition member 38 and the back inner plate 26 along the rear end edge of the second partition member 38 in the left-right direction. Further, a part of the electric wire 52 and a part of the pipe 53 may be arranged to extend in the front-rear direction or the left-right direction along the edge portion of the first partition member 37.

As the heat insulating member, a vacuum heat insulating panel, a urethane, a foamed styrene polymer or the like can be used as the surface partitioning portion 45. Further, the face partition portion 45 may be formed by holding a heat insulating member from above and below by a resin or metal plate. structure.

The partition reinforcing plate 442 may be omitted as long as the partitioning plate 441 is a member having sufficient strength.

The two adjacent divided heat insulating walls 31 may be connected and fixed by screws or the like in addition to the fixing and fixing of the fixing tools 51 and 111 in the above embodiments.

The assembly order of the heat insulating box 12 is only one example, and may be changed as described below. For example, the fixtures 51 and 111 are attached to the back divided heat insulating wall 315, and thereafter, the right divided heat insulating wall 313 or the left divided heat insulating wall 314 is attached to the fixtures 51 and 111.

Each of the sealing members 71, 72, 73, 101, 102, and 114 is not limited to a flexible tape, and a silicone sealer or the like may be used.

Further, the second corner heat insulating member 115 may be provided at a corner portion inside the right side of the inner box 14, and the pipe 53 may be housed in the inside of the accommodating portion 116 of the second corner heat insulating member 115.

The refrigerator 11 may also be provided with a spraying means. In the spraying method, the mist generated by the electrostatic atomization is ejected toward the inside of the storage chamber. The diameter of the droplets is preferably from 1 to 1000 nm. In this case, by providing the fixtures 51 and 111 at the corner portions formed by the two adjacent divided heat insulating walls 31, it is possible to suppress the mist from being passed between the adjacent divided heat insulating walls 31. Dissipated outside the refrigerator.

The fixtures 51, 111 may also be integrally formed on one of the inner panels of the inner box 14.

The split heat insulating wall 31 can also be formed when viewed from the side or the top. It is L-shaped and U-shaped. In other words, the fixing tools 51 and 111 are not limited to the connection and fixing of the plate-shaped divided heat insulating walls 31, and the divided heat insulating walls other than the plate shape, the plate-shaped divided heat insulating walls, and the plate shape may be used. The insulation wall is divided and fixed.

The heat insulating member 15 that divides the heat insulating wall 31, that is, the vacuum heat insulating panel, is not necessarily integrally provided on the inner panel of the inner box 14, and may be integrally provided on the outer panel of the outer box 13. That is, the heat insulating member 15 may be provided so as to be in contact with one of the inner panel of the inner box 14 or the outer panel of the outer box 13.

The heat insulating box 12 can also be assembled in the following manner. First, the box-shaped inner case 14 is formed by fixing and fixing the inner plates 22 to 26 by the fixing tool 51. Unlike the inner box 14, the heat insulating member 15 is previously attached to the outer box 13. Next, the heat insulating box 12 is formed by attaching the inner box 14 to the "assembly formed by the outer box 13 and the heat insulating member 15". In this case, the inner panel constituting the inner box 14 is not limited to a flat plate shape, and may have an L-shape in a plan view.

As described above, the refrigerator of the above embodiment includes the heat insulating box and the fixing member. The heat insulating box is formed in a box shape by a combination of "a plurality of heat insulating walls having heat insulating members inside", and has a storage chamber inside the box shape.
