Description

refrigerator

The embodiment of the present invention relates to a refrigerator.

In recent years, refrigerators have a demand for thinning of the heat insulating wall due to the large capacity of the internal space. In view of such a demand, it is considered to use a vacuum insulation panel as a heat insulating member for a heat insulating wall. Since the heat insulating performance of the vacuum heat insulating panel is superior to the foaming urethane used conventionally, the thickness of the heat insulating wall can be reduced, and thus the space in the refrigerator can be increased in capacity.

Here, in a conventional structure using a foamed urethane as a heat insulating member, a pipe constituting, for example, a refrigeration cycle or an electric wire connected to an electronic component in a refrigerator is buried in the inside of the heat insulating wall. Foamed in urethane.

However, in the case where a vacuum heat insulating panel is used as the heat insulating wall, since the vacuum heat insulating panel has a shape, it is necessary to arrange a pipe or a wire when avoiding the vacuum heat insulating panel in the heat insulating wall. The vacuum insulation panel is thinned or the heat insulation wall body is thickened. In this case, the former method will result in a decrease in thermal insulation performance, while the latter method will result in a reduction in space in the refrigerator.

Specifically, each of the pipes 53 extends from the machine room 21 side through the communication hole 211a of the upper side separation portion 211 toward the refrigerator compartment 39 side. In this case, the communication hole 211a is preferably formed on the upper surface of the fixture 512. After that, each of the pipes 53 passes through the bypass passage 531 and enters the accommodating portion 98 of the corner heat insulating member 83 from the upper end portion of the fixture 512. In this case, the bypass passage 531 is housed in the second heat insulating member 151 of the separating portion 211 as shown in FIG. Then, one of the two pipes 53 of the two pipes 53 passes through the inside of the first heat insulating protruding portion 94 provided in the upper corner heat insulating member 831, and is opened from the opening 95 and the opening 86 toward the cold room. 39 side extension. Then, although not shown in detail in the drawing, the pipes 53 extending from the openings 95 and 86 are connected to the cooler for refrigeration.

The other pipe 53 extends from the opening 97 and the opening 88 toward the first freezing compartment 42 by the inside of the second heat insulating projection 96 provided in the lower corner heat insulating member 832. Although not shown in detail in the drawing, the pipe 53 extending from the openings 97 and 88 is connected to the cold for freezing. But the device. In this case, the openings 86 and 88 are members for guiding a part of the pipe 53 housed inside the fixture 512 to the storage compartment side. A part of the pipe 53 may be introduced into the component storage chamber 212 from the lower end surface of the fixture 512 through the lower partition portion 213.

Each of the pipes 53 has a welded portion 99 at both end portions as shown in Figs. 25 and 27 . The welded portion 99 is formed such that the diameter of the pipe 53 is larger than that of the other pipes, whereby the welded portion of the other pipe can be welded. Each of the pipes 53 is external to the fixture 512 and welded to another pipe to form a connection. The other piping refers to, for example, a piping connected to an evaporator for refrigeration, an evaporator for freezing, and a compressor.

Between the fixing cover 81 and the reinforcing member 82, specifically, between the end portion in the width direction of the fixing cover 81 and the end portion in the width direction of the reinforcing member 82, as shown in Figs. 29 to 31, There is a first sealing member 101. The first sealing member 101 is configured similarly to the first sealing member 71 provided on the fixture 511.

Between the reinforcing member 82 and the right heat insulating wall 313 and between the reinforcing member 82 and the back heat insulating wall 315, as shown in Figs. 29 to 31, a second sealing member 102 is provided. 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 heat insulating wall 313 and the back 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 similarly to the third sealing member 73 provided in a portion where the right heat insulating wall 313 and the back heat insulating wall 315 are in contact with each other.

In this way, the fixture 512 is composed of the fixing cover 81 and the reinforcing member 82. The corner holding heat insulating member 83 is used. 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. Next, by fixing the fixing cover 81 to the reinforcing member 82, the corner heat insulating member 83 and the pipe 53 are also fixed to the inside of the fixture 512.

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 right rear end portion of the second partition member 38 enters between the upper fixing cover 811 and the lower fixing cover 812, and contacts 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 heat insulating wall 313 and the back heat insulating wall 315 face the reinforcing member 82 via the second sealing member 102. In this way, the adjacent right heat insulating wall 313 and the back side heat insulating wall 315 are fixed and fixed by the fixture 512, and the angle formed by the right heat insulating wall 313 and the back side heat insulating wall 315 is maintained to correspond to 90° of 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 heat insulating wall 313 and the back side 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, the inner box 14 In the inside, a partition heat insulating member 105 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. 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, but inside the inner box 14, in the second point The surface partition portion 45 of the partition member 38 and the left inner panel 25 of the inner box 14 are also provided with the same members as the partition portion heat insulating member 105. Similarly to the above-described piping 53, the electric wires 52 may be along The left end edge portion of the second partition member 38 is disposed.

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 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 heat insulating walls 31 by means of a screw 57, such as the left heat insulating wall 314. Next, the back side heat insulating wall 315 is attached to the assembly in which the left side heat insulating wall 314 and the fixture 511 are integrated. In this case, the adjacent heat insulating wall 31 is connected and fixed to the left heat insulating wall 314 and the back heat insulating wall 315 in this case, and a corner portion of the inner right side of the inner box 14 is formed. In this case, the angle of the adjacent wall formed by the left heat insulating wall 314 and the back side heat insulating wall 315 is maintained at 90° in correspondence with the right angle portion of the reinforcing member 55. The other corner portions of the inner box 14 are also formed by joining and fixing the heat insulating wall 31 and the fixture 51. In this way, the inner box 14 of "the angle of the adjacent heat insulating wall 31 is 90 degrees" is formed, and the cubic heat insulating box 12 is formed.

As described above, the fixture 51 defines the angle of the adjacent insulating wall 31 to a specific value, such as 90°. The angle of the adjacent heat insulating walls 31 is not limited to 90°. In this case, the angles of the adjacent heat insulating walls 31 are adjusted to be close to 90°, and each of the heat insulating boxes 12 is provided. The corner formation can be close to 90°. In other words, the angle specified by the fixture 51 does not have to be quite strict. It is tolerable 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 heat insulating wall 313 and the left 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.

According to the above configuration, the electric wire 52 and the pipe 53 are provided in the accommodating space of the heat insulating box 12. In other words, the electric wire 52 and the pipe 53 are not provided inside the heat insulating wall 31. Therefore, it is not necessary to consider a space for accommodating the electric wires 52 and the pipes 53 inside the heat insulating wall 31. In this way, the heat insulating wall 31 can thicken the thickness of the first heat insulating member 15 which is more excellent in heat insulating performance than the second heat insulating member 151. As a result, the refrigerator has excellent heat insulation properties and can sufficiently ensure the space inside the refrigerator.

The electric wire 52 and the pipe 53 are provided at the rear of the inner box 14, and in this case, are provided at the corners deep inside the heat insulating box 12. Therefore, the electric wire 52 and the piping 53 are 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 disposed in the machine room 21 and the parts accommodating chamber 212. Connect with other wires and piping.

Further, a communication hole 211a that penetrates the second heat insulating member 151 of the separating portion 211 and communicates with the machine chamber 21 is provided above the fixture 51. Therefore, the electric wire 52 and the pipe 53 can extend in the up and down direction. As a result, the arrangement of the electric wire 52 and the pipe 53 is facilitated.

The second heat insulating member 151 is configured to be filled. Therefore, the communication hole 211a can be easily formed. Further, the bypass passage 531 of the pipe 53 can be covered by the second heat insulating member 151.

The electric wires 52 and the pipes 53 provided at the corners of the inner box 14 are covered by the fixing covers 54, 81 of the fixture 51. Therefore, it is possible to prevent the food in the storage compartment from coming into contact with the electric wire 52 or the pipe 53 as much as possible. In addition, since the electric wire 52 and the pipe 53 are not seen by the user, the appearance of the inside of the storage compartment can be improved.

The heat insulating box 12 of the refrigerator 11 is formed by combining a plurality of heat insulating walls 31 divided into a plurality of heat insulating walls 31, and is connected and fixed by the fixing members 51 to fix the adjacent two heat insulating walls 31. 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 heat insulating member 15 is composed of a vacuum heat insulating panel. Therefore, the high heat insulating effect of the vacuum heat insulating panel can be obtained, and the heat insulating wall 31 constituting the heat insulating box 12 can be made thin, and as a result, the space in the refrigerator can be increased.

The reinforcing members 55 and 82 of the fixture 51 can function as an angle holding portion that maintains the angle of the adjacent heat insulating walls 31 at 90 degrees. Thereby, the inner box 14 can be formed into a cube. In addition, since the heat insulating box 12 is available inside Since the corner portion of the case 14 is maintained at a 90° configuration, assembly of the heat insulating wall 31 becomes easy.

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

The right heat insulating wall 313 and the left heat insulating wall 314 are connected and fixed by the first partition member 37 and the second partition member 38 in a portion near the center in the vertical direction. Therefore, the front end portion of the right heat insulating wall 313 and the front end portion of the left 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.

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 to cover the abutting portions of the adjacent heat insulating walls 31. In other words, the heat insulating performance is likely to become a contact portion of the two lower 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, 83 cannot be used by the user. As seen, it can further enhance the aesthetics of the interior of the storage compartment.

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. The electric wire 52 leading to the fixture 511 can be guided to the storage compartment side through the openings 59, 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 in the The fixture 512 is integrated. In this case, when the heat insulating wall 31 is connected and fixed by the fixture 51, the electric wire 52 and the piping 53 are also provided in a specific corner portion of the 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.

In addition, in the case where "a part of the pipe 53 is disposed along the right edge portion of the second partition member 38", 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 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 heat insulating wall 31, respectively. In other words, the second sealing members 72, 102 can improve the airtightness between the reinforcing members 55, 82 and the heat insulating wall 31, respectively. In this way, the air can be prevented from entering the inside of the heat insulating box 12 through the abutting portion of the adjacent two heat insulating walls 31, that is, the storage chamber. Therefore, the cold air in the storage compartment can be reduced to the outside of the heat insulation box 12 Leakage and lowering the heat outside the heat insulating box 12 into the storage chamber.

Between the abutting portions of the adjacent two heat insulating walls 31, for example, between the right heat insulating wall 313 and the back side heat insulating wall 315, and between the left heat insulating wall 314 and the back side heat insulating wall 315, Three sealing members 73, 103. 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 the direction in which the corner portions extend, and is divided into two in the case of the embodiment. 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 constituted by sandwiching the first heat insulating member 15 between the outer plates 16 to 20 and the inner plates 22 to 26. The first heat insulating member 15 is composed of a vacuum heat insulating panel which is thin and has excellent heat insulating properties. Therefore, 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.

The second heat insulating member 151 is filled in the separation portion 211. Therefore, the strength of the heat insulating wall 31 can be improved.

Then, in the conventional structure in which the "insulation box is not divided", for example, after the inner box or the outer box is assembled into a box, they are separately combined, and therefore, the assembled part becomes a large and relatively space-consuming component. . In the present configuration, since the heat insulating box 12 is formed by combining a plurality of heat insulating walls 31 divided into a plurality of pieces, the assembly can be miniaturized.

(Second embodiment)

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

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 heat insulating walls 31 refer to the left heat insulating wall 314 and the back side heat insulating wall 315 in the case of the drawing, and are fixed by screws not shown in the drawing. Fixture 111. In other words, the adjacent two 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 insulating plate 25 of the left heat insulating wall 314 and the back inner plate 26 of the rear heat insulating wall 315 are extended. . 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 surface on which the extending portion 112 faces the left inner panel 25 side and extends toward the back heat insulating wall 315 side, and the surface on which the extending portion 113 faces the back inner panel 26 side and extends toward the left heat insulating wall 314 side. Form an orthogonal. Therefore, once the adjacent left heat insulating wall 314 and the back side heat insulating wall 315 are fixed by the fixture 111 is formed to be fixed by the joint, and the angle of the adjacent wall formed by the left heat insulating wall 314 and the back side heat insulating wall 315 is 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 heat insulating walls 31 can be joined 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 panel of the inner box 14 can be maintained as 90°. In this way, the inner box 14, that is, the heat insulating box 12, can be formed into a cube.

A fourth sealing member 114 is provided between the extending portions 112, 113 and the heat insulating wall 31. 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 case 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 is disposed in the space A space other than the heat insulating member 121. 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 121 preferably accounts for 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 thickness of the first heat insulating member 121 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 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. Moreover, 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 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 thickness T ₂ of the second heat insulating member 122, the pipe 53 cannot be accommodated inside the heat insulating wall 31, particularly the first heat insulation. Between the member 121 and the outer box 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, the first insulation member 121 is between 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 have a structure in which a heat insulating member is held from above and below by a resin or a metal plate.

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

The two adjacent 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, 111 are attached to the back side heat insulating wall 315, and thereafter, the right side heat insulating wall 313 or the left side heat insulating wall 314 is attached to the fixtures 51, 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 of the "two adjacent heat insulating walls 31", it is possible to suppress the droplets from passing between the adjacent heat insulating walls 31 toward the refrigerator. Scattered outside.

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

The heat insulating wall 31 may be formed in an L shape or a U shape when viewed from the side surface or the upper surface. In other words, the fixtures 51 and 111 are not limited to the connection and fixing of the plate-shaped heat insulating walls 31, and the heat insulating walls other than the plate shape, the plate-shaped heat insulating wall, and the heat insulating wall other than the plate shape may be used. Connected and fixed.

The first heat insulating member 15 of 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 first heat insulating member 15 may be provided 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 first heat insulating member 15 is previously mounted 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 first 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.

It is preferable that the communication hole 211a is a slit in which the opening of the rear side heat insulating wall 311 is formed. Accordingly, the electric wire 52 and the pipe 53 can be disposed from the rear end of the rear end portion of the upper heat insulating wall 311 through the opening of the communication hole 211a. For this reason, the electric wires 52 and the piping 53 are easy to perform work because the respective end portions do not have to pass through the communication hole 211a from below the separating portion 211. Further, as long as the communication hole 211a is in the shape of the aforementioned slit, Therefore, it is not necessary to make the inner diameter of the communication hole 211a larger than the connecting portion 68 and the welded portion 99. Therefore, the inner diameter of the communication hole 211a can be reduced as much as possible.

In this case, the right heat insulating wall 313 and the left heat insulating wall 314 and the back heat insulating wall 315 are fixed by the fixture 51, and the electric wire 52 and the pipe 53 are inserted into the communication hole 211a, and the upper heat insulating wall is attached. . At this time, the communication hole 211a can be positioned such that the position of the upper heat insulating wall 311 is "the right side heat insulating wall 313 and the left side heat insulating wall 314 and the back side heat insulating wall 315 which are integrated by the fixture 51". The positioning unit functions. In this way, assembly of the heat insulating box 12 is facilitated. The bottom side heat insulating wall 312 is also the same.

The communication hole 211a may not be located directly above the fixture 51. For example, it may be located on the heat insulating member 15 of the back side heat insulating wall 315. According to this, the shape of the slit of the communication hole 211a can be shortened, and when the foamed urethane is filled, the leakage of the foamed urethane from the communication hole 211a can be reduced.

Further, in this case, the upper end portion of the back side heat insulating wall 315, more specifically, the "heat insulating member 15 of the back side heat insulating wall 315 and the upper outer plate 16 of the upper side heat insulating wall 311" As the separation portion 211, the electric wire 52 and the pipe 53 are bent from the fixture 51 toward the back outer panel 20 side of the back heat insulating wall 315, and pass through the separation portion 211. In this way, the electric wire 52 and the pipe 53 can be inserted into the through hole 211a of the heat insulating member 15 of the back heat insulating wall 315.

The bypass passage 531 of the pipe 53 can also be housed in the machine room 21.

As described above, in the refrigerator of the above embodiment, the electric wire and the distribution The tube is placed in the accommodating space of the heat insulating box, and is not disposed inside the heat insulating wall. Therefore, it is not necessary to consider: in the inside of the heat insulating wall, a space for accommodating wires and piping is secured. In this way, the heat insulating wall can strongly thicken the thickness of the first heat insulating member having better heat insulating properties than the second heat insulating member. As a result, the refrigerator has excellent heat insulation properties and can sufficiently ensure the space inside the refrigerator.
