<2. Characteristics of each heat insulating material>
Here, characteristics of each heat insulating material (“vacuum heat insulating material”, “foam heat insulating material”, and “specific heat insulating material G”) used in the refrigerator 1 of the present embodiment will be described.

The "vacuum heat insulating material" is also called VIP (Vacuum Insulation Panel), and is, for example, a heat insulating material including an exterior body and a core material housed in the exterior body, and the inside of the exterior body is decompressed. The core material is, for example, a fiber material such as glass wool or a porous body such as foam.

The "foamed heat insulating material" is a foamed heat insulating material such as urethane foam. The foamed heat insulating material is formed by being injected into the interior of the door 11 in a fluid state and heated to foam.

“The specific heat insulating material G” is a heat insulating material containing aerogel, xerogel, or cryogel, and is an example of a “heat insulating member”. The term "including aerogel, xerogel, or cryogel" is used to mean "including one or more of aerogel, xerogel, or cryogel". Aerogels, xerogels, and cryogels are low density structures (dry gels), respectively. The "aerogel" is, for example, a porous substance in which the solvent contained in the gel is replaced with gas by supercritical drying. The "xerogel" is a porous substance in which the solvent contained in the gel is replaced with a gas by evaporation drying. The "cryogel" is a porous substance in which the solvent contained in the gel is replaced with a gas by freeze-drying.

It should be noted that some airgels can be dried without using supercritical drying, for example, by introducing a specific element. The term "airgel" as used herein also includes such an airgel. That is, the term "aerogel" as used in the present specification is not limited to those produced by using supercritical drying, but widely means various materials distributed as "aerogel". As an aerogel that does not require supercritical drying, for example, an organic-inorganic hybrid aerogel in which an organic chain such as a methyl group is introduced into a molecular network of silicon dioxide is known, such as PMSQ (CH ₃ SiO _1.5 ) aerogel. There is. However, these are just examples.

Aerogels, xerogels, and cryogels are ultra-low-density dry porous bodies having a large number of fine pores (voids) and an extremely high porosity (porosity of 90% or more, preferably 95% or more). The density of the dry porous body is, for example, 150 mg / cm ³ or less. Aerogels, xerogels, and cryogels have, for example, a structure in which silicon dioxide and the like are bound in a beaded shape, and have many voids at the nanometer level (for example, 100 nm or less, preferably 2 nm to 50 nm). Since it has nanometer-level pores and a lattice structure in this way, the mean free path of gas molecules can be reduced, the heat conduction between gas molecules is very small even at normal pressure, and the thermal conductivity is very small. It is a thing. For example, aerogels, xerogels, and cryogels have fine voids that are smaller than the mean free path of air.

As the aerogel, xerogel, and cryogel, silicon, aluminum, iron, copper, zirconium, hafnium, magnesium, inorganic aerogel consisting of metal oxides such as yttrium, inorganic xerogel, or inorganic cryogel may be, for example, silica aerogel containing silicon dioxide. , Silica xerogel, silica cryogel, or the like. These are structures in which silica (SiO 2) fine particles having a diameter of 10 nm to 20 nm are connected and have pores with a width of several tens of nm. These have a very low thermal conductivity (0.012 W/(m·K)- 0.02 W/(m·K) Furthermore, since these silica fine particles and pores are smaller than the wavelength of visible light and do not scatter visible light, they have high light transmittance. The material constituting the cryogel may be carbon or the like.

Aerogels, xerogels, and cryogels can have arbitrary properties (for example, elasticity and flexibility) by selecting the materials. For example, by using polypropylene as a material, high elasticity or flexibility can be provided.

Airgel, xerogel, and cryogel may each form the specific heat insulating material G by themselves. Alternatively, the aerogel, the xerogel, and the cryogel may form a specific heat insulating material G that is a composite heat insulating material by immersing another material (for example, a fiber structure) in a precursor state. .. In this case, the fibrous structure acts as a reinforcing material or a support for reinforcing and supporting the dry gel, and in order to obtain a flexible composite heat insulating material, a flexible woven fabric, knitted fabric, or nonwoven fabric. Etc. are used, and more preferably, felt or blanket-shaped ones are used. As the material of the fiber structure, for example, in addition to organic fibers such as polyester fibers, inorganic fibers such as glass fibers can be used.

The above fiber structure is, for example, a natural polymer chitosan. The specific heat insulating material G includes a three-dimensional network structure of hydrophobized fine chitosan fibers and has an extremely high porosity (96 to 97% of the volume is voids). The hydrophobization keeps the homogeneous nanostructure of hydrophilic chitosan aerogel, while increasing the moisture resistance, which is a problem of the material composed of polysaccharide nanofibers, and having water repellency.

The specific heat insulating material G may be, for example, a heat insulating material in which polypropylene foam and one selected from silica aerogel, xerogel, and cryogel are combined.

The thermal conductivity of the specific heat insulating material G is higher than that of the vacuum heat insulating material, but lower than the thermal conductivity of the foam heat insulating material. The heat insulating property of the specific heat insulating material G does not reach that of the vacuum heat insulating material, but is superior to that of the foam heat insulating material. The thermal conductivity of the specific heat insulating material G is, for example, 0.010 W/(m·K) to 0.015 W/(m·K). The thermal conductivity of the vacuum heat insulating material is, for example, 0.003 W/(m·K) to 0.005 W/(m·K). The thermal conductivity of the foamed heat insulating material is, for example, 0.020 W/(m·K) to 0.022 W/(m·K). Note that these numerical values are merely examples.

When the specific heat insulating material G has flexibility, the flexibility (easiness of bending) of the specific heat insulating material G is higher than that of the vacuum heat insulating material and higher than that of the foam heat insulating material, for example. When the specific heat insulating material has elasticity, the elasticity of the specific heat insulating material G is higher than that of the vacuum heat insulating material (substantially inelastic), and the elasticity of the foamed heat insulating material (substantially inelastic). Closer to) higher than.

The frame 51 is made of synthetic resin, for example.

The front plate 52 (see FIG. 5) is attached to the frame 51 and is located at the front end of the left refrigerator door 11Aa. The front plate 52 is a plate member along the vertical direction and the horizontal direction, and forms the front surface of the left refrigerating chamber door 11Aa. The front plate 52 is, for example, a glass plate. However, the front plate 52 is not limited to the glass plate, and may be formed of a synthetic resin or another material.

The rear surface member 53 is attached to the frame body 51 from the side opposite to the front surface plate 52, and is located at the rear end portion of the left refrigerating compartment door 11Aa. The rear surface member 53 forms the rear surface of the left refrigerating chamber door 11Aa.
The rear surface member 53 is made of synthetic resin, for example.

The rear surface member 53 has a rib (projection portion, bulge portion) 61 protruding rearward. The rib 61 projects from the rear member 53 toward the refrigerating compartment 27A (storage compartment) with the left refrigerating compartment door 11Aa closed with respect to the housing 10. In the present specification, the term “rib” is a name for convenience of description, and broadly means a portion protruding rearward from the rear surface member 53, and is not limited to a specific shape or function.

The rib 61 is formed in an annular shape, which is one size smaller than the outer shape of the frame body 51, for example. The term “annular” as used in the present specification is not limited to the case where the entire circumference is completely continuous, and includes the case where a cutout or the like is provided and a part of the circumference is interrupted.

And a rib (right rib) 61d extending vertically along the right side member 51d.

The rib 61 is provided, for example, in order to prevent cold air in the refrigerating compartment 27A (storage compartment) from escaping from the gap between the left refrigerating compartment door 11Aa and the housing 10. The rib 61 projects relatively rearward. For example, the protruding amount of the rib 61 to the rear is more than half the thickness of the outer member 50 excluding the rib 61 in the depth direction. In this embodiment, the protrusion amount of the rib 61 is larger than the thickness of the outer shell member 50 excluding the rib 61 in the depth direction. Further, the rib 61 is provided with a lighting unit 62 that illuminates the inside of the refrigerating chamber 27A when the left refrigerating chamber door 11Aa is opened. The illumination unit 62 will be described later.

The gasket (sealing member, cushioning member) 55 is attached to the rear member 53. More specifically, the rear member 53 has a throat 63 that is a recess that is recessed toward the inside of the left refrigerator door 11Aa. For example, the throat 63 is formed in an annular shape surrounding the outer peripheral side of the rib 61. In the present embodiment, the throat 63 is along the throat (upper throat) 63a extending in the horizontal direction along the upper side member 51a, the throat (lower throat) 63b extending in the horizontal direction along the lower side member 51b, and the left side member 51c.

The first region has a light-transmitting property, and when the light source of the operation panel unit 71 emits light, for example, the surface of the operation panel unit 71 is visible from the outside of the refrigerator 1. On the other hand, in the second region, the rear surface of the front plate 52 is coated with a colored paint, and the inside of the left refrigerating chamber door 11Aa cannot be seen from the outside.
Note that the operation panel unit 71 may be a unit that accepts a user operation via a physical button or switch provided on the left refrigerating compartment door 11Aa, instead of the above example.

Similarly, inside the left refrigerating compartment door 11Aa, a second accommodating portion (second accommodating space) 76 in which the opening operation operation unit 72 is detachably accommodated by the second case 82 (see FIG. 6) is formed.

<3.3 Overview of the internal configuration of the left refrigerator door>
FIG. 5 is a sectional view taken along line F5-F5 of the left refrigerating compartment door 11Aa shown in FIG. FIG. 6 is a sectional view taken along line F6-F6 of the left refrigerating compartment door 11Aa shown in FIG. As shown in FIGS. 5 and 6, the left refrigerating compartment door 11Aa has, for example, a first case 81, a second case 82, a reinforcing member 83, a foam heat insulating material 84, a specific heat insulating material G, and a tape member 85. Since the second case 82 has the same configuration as the first case 81, detailed description of the second case 82 and the specific heat insulating material G attached to the second case 82 is omitted.

<3.4 First case>
The first case 81 is arranged along the rear surface of the front plate 52. The first case 81 is formed in a bowl shape with the front and right sides open. That is, the first case 81 includes a rear wall 81a, an upper wall 81b, a lower wall 81c, a left side wall 81d, and an overhanging portion 81e. The rear wall 81a is provided at a position away from the front plate 52 of the left refrigerating chamber door 11Aa, and extends substantially parallel to the front plate 52. The upper wall 81b extends forward from the upper end of the rear wall 81a and is in contact with the rear surface of the front plate 52. The lower wall 81c extends forward from the lower end of the rear wall 81a and is in contact with the rear surface of the front plate 52. The left side wall 81d extends forward from the left end of the rear wall 81a and is in contact with the rear surface of the front plate 52. The left side wall 81d has a hole 81da through which the cable C1 extending from the operation panel unit 71 passes (see FIG. 10). The cable C1 is connected to the control board 16 of the refrigerator body 5 via the hinge 30. The overhanging portion 81e extends from the front end portion of the left side wall 81d toward the left. The overhanging portion 81e extends along the rear surface of the front plate 52. The overhanging portion 81e overlaps with at least a part of the third portion 85c of the tape member 85, which will be described later, when viewed from the front of the refrigerator 1.

As a result, a first accommodating portion 73 accommodating the operation panel unit 71 is formed between the rear wall 81a of the first case 81 and the front plate 52. The operation panel unit 71 is fixed to the inner surface of the first case 81 by, for example, an engaging portion (not shown). The term "case" as used herein is not limited to a member formed in a box shape, but includes a member whose directions are open as in the above example. The first case 81 is an example of an “internal component”. In the area of the left refrigerating room door 11Aa where the first case 81 is provided, the foam insulating material 84 is provided at least by the amount in which the first case 81 is provided in the thickness direction (depth direction) of the left refrigerating room door 11Aa. The space to be filled becomes smaller.

The right end of the first case 81 has an engaging portion 81f that engages with the frame 51 of the left refrigerating compartment door 11Aa. The right end portion of the first case 81 is relatively firmly fixed to the frame body 51. On the other hand, the left end portion of the first case 81 is not fixed to the frame body 51. The left end portion of the first case 81 is fixed to the rear surface of the front plate 52 by a tape member 85 described later, for example.

In the present embodiment, the first case 81 is arranged inside the left refrigerating compartment door 11Aa at a position biased to the right. The first case 81 overlaps with the throat 63d of the rear member 53 when the refrigerator 1 is viewed from the front. Therefore, the space filled with the foamed heat insulating material 84 is further reduced between the first case 81 and the throat 63d.

<3.5 Reinforcement member>
The reinforcing member 83 is provided at the right end of the left refrigerating compartment door 11Aa and extends in the vertical direction. The reinforcing member 83 is, for example, a metal member having a U-shaped cross-sectional shape. The reinforcing member 83 is provided, for example, to suppress the deformation of the frame body 51 due to the temperature difference between the temperature of the refrigerating chamber 27A and the temperature outside the refrigerator 1. The reinforcing member 83 is provided between the first case 81 and the throat 63d in the depth direction of the refrigerator 1. Therefore, in the region where the first case 81, the reinforcing member 83, and the throat 63d overlap, the space filled with the foamed heat insulating material 84 becomes smaller. Further, the inside of the reinforcing member 83 is one of the places where the foamed heat insulating material 84 is difficult to be filled.

<3.6 Foam insulation>
The foam heat insulating material 84 is provided inside the outer member 50. For example, the foamed heat insulating material 84 is filled between the front plate 52 and the rear surface member 53 in a region outside the first case 81. The foamed heat insulating material 84 is also filled between the specific heat insulating material G and the rear surface member 53.

Here, an example of a manufacturing method for the left refrigerator door 11Aa will be described first. First, the frame 51 is formed by combining the above-described upper side member 51a, lower side member 51b, left side member 51c, and right side member 51d. Next, the front plate 52 is attached to the front end of the frame body 51 to form an intermediate assembly. Next, the intermediate assembly is placed on the workbench with the front plate 52 facing down, and the first case 81 and the second case 82 are attached to the frame body 51.

Next, the specific heat insulating material G described later is attached to the first case 81 and the second case 82. The specific heat insulating material G may be attached to the first case 81 and the second case 82 before attaching the first case 81 and the second case 82 to the frame 51. Next, the left end portions of the first case 81 and the second case 82 are fixed to the front plate 52 by the tape member 85 described later. Next, the foamed heat insulating material 84 before foaming is supplied to the inside of the frame body 51. Next, the rear surface member 53 is attached to the rear end portion of the frame body 51. Next, the foam heat insulating material 84 is heated to foam the foam heat insulating material 84. Finally, the operation panel unit 71 and the open operation operation unit 72 are housed in the first housing unit 73 and the second housing unit 76. As a result, the left refrigerator compartment door 11Aa is manufactured.

<3.7 Specified heat insulating material>
The specific heat insulating material G is provided inside the outer member 50. The specific heat insulating material G overlaps with the first case 81 when the refrigerator 1 is viewed from the front. In the present embodiment, the specific heat insulating material G overlaps with the first case 81, the throat 63d, and the reinforcing member 83 when the refrigerator 1 is viewed from the front. In the present embodiment, the specific heat insulating material G is arranged between the first case 81 and the rear surface member 53. For example, at least a part of the specific heat insulating material G is arranged between the first case 81 and the throat 63d. For example, at least a part of the specific heat insulating material G is arranged between the first case 81 and the reinforcing member 83.

In the present embodiment, the specific heat insulating material G has a size that covers the entire first case 81 when the refrigerator 1 is viewed from the front. For example, the specific heat insulating material G is formed in a bowl shape along the rear wall 81a, the upper wall 81b, the lower wall 81c, the left side wall 81d, and the overhanging portion 81e of the first case 81, and the rear wall 81a of the first case 81. , The upper wall 81b, the lower wall 81c, the left side wall 81d, and the overhanging portion 81e.

In the present embodiment, the specific heat insulating material G is a molded product in which irregularities are formed according to the shape of the first case 81, and has rigidity. For example, the specific heat insulating material G is processed into a shape along the outer shape of the first case 81 by setting a sheet-shaped material in a mold corresponding to the shape of the first case 81, and heating and pressing the material. Has been done. The specific heat insulating material G includes a portion bent along the outer shape of the first case 81. For example, the specific heat insulating material G includes a portion bent along a bent portion between the rear wall 81a and the left side wall 81d of the first case 81. When the specific heat insulating material G is a molded product having rigidity, the specific heat insulating material G may be easily attached to the first case 81, and the workability in assembly may be improved.

The specific heat insulating material G may be a flexible sheet instead of the molded product. In this case, the specific heat insulating material G is attached to the first case 81 while being bent along the outer shape of the first case 81, and includes a portion that is bent along the outer shape of the first case 81.

The specific heat insulating material G is fixed to the first case 81 by, for example, a double-sided tape or an adhesive. The specific heat insulating material G has a hole ha that faces the hole 81da of the first case 81 (see FIG. 10). The cable C1 extending from the operation panel unit 71 extends through the hole 81da of the first case 81 and the hole ha of the specific heat insulating material G into the inside of the left refrigerating compartment door 11Aa.

<3.8 tape member>
The tape member 85 fixes the left end of the first case 81 to the front plate 52. The tape member 85 has, for example, a first portion (first end portion) 85a, a second portion (second end portion) 85b, and a third portion 85c. For example, the first portion 85a is attached to the rear surface of the specific heat insulating material G at a position corresponding to the left end portion of the first case 81. The second portion 85b is attached to the rear surface of the front plate 52. The third portion 85c extends between the first portion 85a and the second portion 85b, and connects the first portion 85a and the second portion 85b. The third portion 85c is separated from the front plate 52 of the left refrigerator door 11Aa. According to such a configuration, a space is formed between the third portion 85c of the tape member 85 and the front plate 52 because the tape 85 is an obstacle and the foamed heat insulating material 84 is difficult to be filled. The sex may be reduced. In the present embodiment, at least a portion of the specific heat insulating material G (for example, a portion that covers the overhanging portion 81e of the first case 81) is located between the third portion 85c of the tape member 85 and the front plate 52.

In the present embodiment, the tape member 85 is attached to the specific heat insulating material G, and the left end portion of the first case 81 is fixed to the front plate 52 of the left refrigerating compartment door 11Aa via the specific heat insulating material G. Alternatively, the first portion 85a may be attached directly to the first case 81 or may be attached to both the specific insulation G and the first case 81.

The tape member 85 is not limited to the fixing tape member. For example, the tape member 85 may be a tape member provided to reduce the foaming pressure acting on the boundary between the first case 81 and the front plate 52 when the foamed heat insulating material 84 is foamed. That is, if the foaming pressure acting on the boundary between the first case 81 and the front plate 52 is excessively large, the foamed heat insulating material 84 penetrates between the first case 81 and the front plate 52. As a result, the first case 81 and the operation panel unit 71 may be displaced in the direction away from the front plate 52, and the detection accuracy of the touch detection unit of the operation panel unit 71 may be lowered. Therefore, by providing the tape member 85 as described above, the flow rate of the foamed heat insulating material 84 toward the boundary between the first case 81 and the front plate 52 is limited, and the foamed heat insulating material 84 moves from the first case 81 to the front plate 52. You may reduce the foaming pressure which acts on a boundary. In this case, the tape member 85 may have a size ranging from the upper end to the lower end of the first case 81, for example.

FIG. 7 is a plan view showing an example of the tape member 85. In the third portion 85c of the tape member 85, the foam insulation 84 during foaming is moved from the space between the tape member 85 and the rear surface member 53 to the space between the third portion 85c of the tape member 85 and the front plate 52. It may have one or more (for example, a plurality of) holes hb through which an appropriate amount is allowed to flow. Even when such a tape member 85 is provided, the packing density of the foamed heat insulating material 84 between the third portion 85c of the tape member 85 and the front plate 52 is smaller than that in other places, and the heat insulation is performed. Sex may decrease. Therefore, in the present embodiment, the specific heat insulating material G is provided so that at least a part of the specific heat insulating material G is located between the third portion 85c of the tape member 85 and the front plate 52.

According to the above configuration, in the area of the left refrigerating compartment door 11Aa where the first case 81 is provided, the space filled with the foamed heat insulating material 84 is small in the thickness direction of the left refrigerating compartment door 11Aa. Become. Therefore, the possibility that dew condensation will occur on the frame 51 and the front plate 52 around the area where the first case 81 is provided increases. However, in the present embodiment, the specific heat insulating material G that overlaps the first case 81 when the refrigerator 1 is viewed from the front is provided. As a result, for example, the heat insulating property behind the first case 81 is improved, and it is possible to suppress the occurrence of dew condensation on the frame 51 and the front plate 52 around the area where the first case 81 is provided.

In the present embodiment, the specific heat insulating material G includes a portion bent along the outer shape of the first case 81. According to such a configuration, it is possible to suppress the formation of a space (a space having low heat insulating property) in which the foamed heat insulating material 84 is not filled between the specific heat insulating material G and the first case 81. Thereby, the heat insulating property can be further improved.

In the present embodiment, the specific heat insulating material G has a portion that overlaps with at least a part of the third portion 85c of the tape member 85 when the refrigerator 1 is viewed from the front. According to such a configuration, it is possible to improve the heat insulating property of the region where the foamed heat insulating material 84 is less likely to be filled due to the tape member 85. As a result, it is possible to suppress dew condensation on the front plate 52 in the region where the tape member 85 is provided.

The specific heat insulating material G may be provided for the second case 82 instead of/in addition to the first case 81. In this case, the second case 82 is an example of “internal component”. The electronic components housed in the first case 81 or the second case 82 are not limited to the operation panel unit 71 and the opening operation operation unit 72. The electronic component housed in the first case 81 or the second case 82 may be, for example, a display device such as a liquid crystal display, an organic EL (Organic Electro-Luminescence) display, a plasma display, or a camera. In this case, the display device and the camera correspond to an example of “electronic component”. These modifications can be applied to all the embodiments described below.

(Second embodiment)
Next, a second embodiment will be described. The second embodiment is different from the first embodiment in that the first case 81 and the second case 82 themselves are formed of the specific heat insulating material G. The configuration other than that described below is the same as that of the first embodiment. Further, since the second case 82 has the same configuration as the first case 81, the description thereof will be omitted.

FIG. 8 is a sectional view showing the left refrigerating compartment door 11Aa of the second embodiment. In the present embodiment, the first case 81 itself is formed of the specific heat insulating material G. The first case 81 is a molded product having rigidity. The operation panel unit 71 is housed inside the first case 81. The first case 81 overlaps the operation panel unit 71 when the refrigerator 1 is viewed from the front. For example, the first case 81 covers the entire operation panel unit 71 when the refrigerator 1 is viewed from the front. The first case 81 has a portion that overlaps at least a part of the third portion 85c of the tape member 85 when the refrigerator 1 is viewed from the front. In the present embodiment, the operation panel unit 71 is an example of an “internal component”, and the first case 81 is an example of an “insulating member”. According to such a configuration, it is possible to improve the heat insulating property as in the first embodiment.

Note that, as described above, the electronic component housed in the first case 81 or the second case 82 may be, for example, a display device or a camera. In this case, the display device and the camera are examples of “internal components” and correspond to examples of “electronic components”. For example, the display device and the camera are arranged along the rear surface of the front plate 52.

(Third Embodiment)
Next, the third embodiment will be described. The third embodiment is different from the first embodiment in that the specific heat insulating material G is provided over the first case 81 and the front plate 52 of the left refrigerating room door 11Aa.

FIG. 9 is a sectional view showing the left refrigerating compartment door 11Aa of the third embodiment. In the present embodiment, the specific heat insulating material G is formed in a sheet shape, for example, and has flexibility. The specific heat insulating material G has, for example, a first portion (first end portion) 91a, a second portion (second end portion) 91b, and a third portion 91c. The first portion 91a is attached to the left end of the rear surface of the first case 81. For example, the first portion 91a is fixed to the first case 81 with a double-sided tape or an adhesive. The second portion 91b is attached to the rear surface of the front plate 52. For example, the second portion 91b is fixed to the front plate 52 with double-sided tape or an adhesive. The third portion 91c extends between the first portion 91a and the second portion 91b and connects the first portion 91a and the second portion 91b.

In the present embodiment, the specific heat insulating material G is provided in the same role as the tape member 85 of the first embodiment. That is, the specific heat insulating material G is for the purpose of fixing the left end portion of the first case 81 to the front plate 52 and/or the foaming pressure acting on the boundary between the first case 81 and the front plate 52 from the foam heat insulating material 84. It is provided for the purpose of reducing. For example, the third portion 91c of the specific heat insulating material G may have one or more (for example, a plurality of) holes hb through which the foaming heat insulating material 84 that is being foamed passes, similarly to the tape member 85 of the first embodiment. Good.

According to the above configuration, the specific heat insulating material G is provided at a position overlapping a part of the first case 81 when the refrigerator 1 is viewed from the front, and thus when the refrigerator 1 is viewed from the front. The heat insulating property of the region overlapping with the first case 81 is improved, and the occurrence of dew condensation on the front plate 52 can be suppressed. In addition, it is possible to improve the heat insulating property of a region which is unlikely to be filled with the foamed heat insulating material 84 which may occur near the third portion 91c of the specific heat insulating material G.

(Fourth Embodiment)
Next, a fourth embodiment will be described. The fourth embodiment is different from the first embodiment in that the specific heat insulating material G is provided in substantially the entire area of the left refrigerating room door 11Aa when the refrigerator 1 is viewed from the front. The configuration other than that described below is the same as that of the first embodiment.

FIG. 10 is a sectional view showing the left refrigerating compartment door 11Aa of the fourth embodiment.

The first portion 95a has a hole hc through which a structure ST (for example, a protrusion or a rib) provided on the inner surface of the right side member 51d is passed. The first portion 95a is in contact with the inner surface of the right side member 51d as the structure ST is passed through the hole hc.

The second portion 95b is provided along the rear wall 81a of the first case 81. The third portion 95c is provided along the left side wall 81d of the first case 81. The third portion 95c is provided with a hole ha that faces the hole 81da of the left side wall 81d of the first case 81 and that allows the cable C1 to pass therethrough. The fourth portion 95d is provided along the rear surface of the front plate 52.

The fifth portion 95e is provided along the inner surface of the left side member 51c of the frame body 51. The fifth portion 95e has a hole hc through which a structure ST (for example, a protrusion or a rib) provided on the inner surface of the left side member 51c is passed. The fifth portion 95e is in contact with the inner surface of the left side member 51c as the structure ST is passed through the hole hc.

As shown in FIG. 11, the sixth portion 95f is provided along the rear wall of the second case 82. The seventh portion 95g is provided along the inner surface of the upper side member 51a of the frame body 51.

Note that one or more of the first portion 95a to the eighth portion 95h may be omitted. For example, the specific heat insulating material G may have only the first portion 95a, the fifth portion 95e, the seventh portion 95g, and the eighth portion 95h.

(Fifth Embodiment)
Next, the fifth embodiment will be described. The fifth embodiment is different from the fourth embodiment in that one or more holes hd are provided in the fourth portion 95d of the specific heat insulating material G of the fourth embodiment. The configuration other than that described below is the same as that of the fourth embodiment.

FIG. 12 is a sectional view showing the left refrigerating compartment door 11Aa of the fifth embodiment. In the present embodiment, the front plate 52 is a glass plate. Therefore, in the present embodiment, the front plate 52 is referred to as the glass plate 52. Here, the left refrigerator compartment door 11Aa is a so-called frameless door, and does not have a support portion that supports the glass plate 52 from the front. The frame 51 has a support portion 51e that supports the peripheral end portion of the glass plate 52 from the rear side. The peripheral edge portion of the glass plate 52 is fixed to the support portion 51e of the frame body 51 with a double-sided tape or an adhesive. In this case, the double-sided tape or the adhesive has high reliability for long-term use. When the double-sided tape or the adhesive is used in the refrigerator 1 for a period longer than the product life, corrosion or the like may occur. When the double-sided tape or the adhesive is corroded, the adhesive force for holding the glass plate 52 is weakened, and there is a possibility that the glass plate 52 may come off from the frame 51 when a strong impact is applied.

As a result, it is possible to prevent dew condensation from forming on the frame body 51 and the front plate 52.

Note that, instead of the above configuration, the specific heat insulating material G is provided between the first portion 162a of the fixing member 162 and the flat surface portion 161a of the fixing portion 161 (that is, between the fixing member 162 and the rear surface member 53). May be good.

(16th Embodiment)
Next, a sixteenth embodiment will be described. The 16th embodiment is different from the 15th embodiment in that the specific heat insulating material G is provided between the rail mounting portion 35b and the fixing portion 161 of the rear surface member 53. The configuration other than that described below is the same as that of the fifteenth embodiment. The configuration of this embodiment is also applicable to the ice making chamber door 11C, the small freezing chamber door 11D, and the main freezing chamber door 11E.

FIG. 26 is a sectional view showing the vegetable compartment door 11B of the sixteenth embodiment. In the present embodiment, the specific heat insulating material G is formed in a sheet shape, for example, and is sandwiched between the rail mounting portion 35b and the fixing portion 161 of the rear surface member 53. That is, the specific heat insulating material G is provided as a part of the outer shell member 50. The specific heat insulating material G overlaps with at least the flat surface portion 161a of the fixing portion 161 and the first portion 162a of the fixing metal fitting 162 when the refrigerator 1 is viewed from the front. The specific heat insulating material G has a plurality of holes hi through which the fastening members 151 are passed. According to such a configuration, the heat insulating property of the vegetable compartment door 11B can be improved and dew condensation can be suppressed on the frame body 51 and the front plate 52 as in the fifteenth embodiment.

(17th Embodiment)
Next, a seventeenth embodiment will be described. The 17th embodiment is different from the 15th embodiment in that the specific heat insulating material G covers the recess 110 for the handle of the vegetable room door 11B. The configuration other than that described below is the same as that of the fifteenth embodiment. The configuration of this embodiment is also applicable to the ice making chamber door 11C, the small freezing chamber door 11D, and the main freezing chamber door 11E.

FIG. 27 is a sectional view showing the left refrigerating compartment door 11Aa of the seventeenth embodiment. As shown in FIG. 27, the upper end portion of the vegetable compartment door 11B has a depression 110 for holding. The recess 110 is provided in the upper side member 51a of the outer shell member 50, and is recessed toward the inside (that is, downward) of the outer shell member 50. The depression 110 is a depression that the user holds when opening the vegetable compartment door 11B. The recess 110 extends in the lateral width direction.

In the present embodiment, the specific heat insulating material G is provided on the upper end portion inside the outer shell member 50. The specific heat insulating material G overlaps the recess 110 when the refrigerator 1 is viewed from the front. Moreover, the specific heat insulating material G overlaps with the depression 110 when the refrigerator 1 is viewed from above. For example, the specific heat insulating material G has a length extending from the left end portion and the right end portion of the recess 110 and extends in the lateral width direction. The depression 110 is an example of the “specific structure portion”.

Specifically, the inner surface 111 (the surface exposed inside the outer shell member 50) of the upper side member 51a of the outer shell member 50 has a protrusion 112 that protrudes into the outer shell member 50 in correspondence with the depression 110. The protrusion 112 has a curved surface corresponding to the shape of the recess 110.

The specific heat insulating material G is attached to the inner surface 111 of the upper side member 51a and covers the protrusion 112.
In the present embodiment, the specific heat insulating material G is a molded product formed according to the shape of the protrusion 112 and has rigidity. The specific heat insulating material G may be a flexible sheet. At least a part of the specific heat insulating material G is located between the vegetable compartment 27B (storage compartment 27) and the depression 110.

In the present embodiment, the specific heat insulating material G includes the first portion 171a, the second portion 171b, and the third portion 171c. The first portion 171a is provided inside the outer shell member 50 along the surface of the protrusion 112, and includes a bent portion corresponding to the shape of the recess 110. The second portion 171b is arranged along the rear surface of the front plate 52. For example, the second portion 171b extends below the lower end of the rib 61a. The third portion 171c is arranged along the inner surface of the upper side member 51a.

According to the above-described configuration, a space filled with the foamed heat insulating material 84 in the thickness direction of the vegetable compartment door 11B is provided around the region of the vegetable compartment door 11B where the hand-holding depression 110 is provided. It becomes smaller. Therefore, there is a high possibility that dew condensation will occur inside the frame 51, the front plate 52, and the recess 110 around the region where the recess 110 is provided. However, in the present embodiment, the specific heat insulating material G that overlaps with the recess 110 when the refrigerator 1 is viewed from the front is provided.

Here, in the housing 10 of the refrigerator main body 5, the refrigerating chamber 27A and the vegetable compartment 27B are storage chambers in the same refrigerating temperature zone. Therefore, the first partition 28 between the refrigerating compartment 27A and the vegetable compartment 27B has a heat insulating property as compared with the second partition 29 located between the vegetable compartment 27B and the ice making compartment 27C and the small freezing compartment 27D. Has a small structure. For example, the first partition 28 is made of a general synthetic resin member and does not include the foamed heat insulating material 11c. In other words, there is no wall with high heat insulation behind the upper end of the vegetable compartment door 11B. For this reason, the cold air supplied from the cold air outlet h1 of the refrigerating compartment 27A easily contacts the upper end of the vegetable compartment door 11B and easily lowers the temperature of the upper end of the vegetable compartment door 11B. Therefore, the upper rib 61a of the vegetable compartment door 11B is formed larger than the lower rib 61b.

However, in the present embodiment, the specific heat insulating material G is provided at the upper end of the inside of the outer member 50, and the heat insulating property of the upper end of the outer member 50 is improved. When the heat insulating property of the upper end portion of the outer member 50 is improved, the rib 61a on the upper side of the vegetable compartment door 11B can be reduced. If the upper rib 61a can be made smaller, the vegetable compartment containers 13Ba and 13Bb can be made larger, and the appearance of the vegetable compartment 27B can be improved (the opening can be made larger).

(19th Embodiment)
Next, a nineteenth embodiment will be described. The nineteenth embodiment differs from the seventeenth embodiment in that it relates to the main freezer compartment door 11E. The configuration other than that described below is the same as that of the 17th embodiment. The configuration of this embodiment can also be applied to the vegetable compartment 27B, the ice making chamber door 11C, and the small freezing chamber door 11D.

FIG. 30 is a sectional view showing a main freezer compartment door 11E of the nineteenth embodiment.

With this configuration, it is possible to improve the heat insulation of the main freezer compartment 27E. When the left specific heat insulating material G1 and the right specific heat insulating material G2 are arranged behind the vacuum heat insulating material 130, the left specific heat insulating material G1 and the right specific heat insulating material G1 are positioned after the vacuum heat insulating material 130 is positioned inside the frame 51. The specific heat insulating material G2 can be installed and the rear surface member 53 can be attached. According to such a configuration, workability may be improved in some cases.

(22nd Embodiment)
Next, the 22nd embodiment will be described. The twenty-second embodiment is different from the twenty-first embodiment in that the specific heat insulating material G is provided as a protection member for the vacuum heat insulating material 130. The configuration other than that described below is the same as that of the 21st embodiment. The configuration of this embodiment is also applicable to the left refrigerating compartment door 11Aa, the right refrigerating compartment door 11Ab, the vegetable compartment 27B, the ice making compartment door 11C, and the small freezing compartment door 11D.

FIG. 33 is a sectional view showing the main freezer compartment door 11E of the 22nd embodiment. In the present embodiment, the main freezing chamber door 11E has a left specific heat insulating material G1 and a right specific heat insulating material G2 as the specific heat insulating material G.

The sheet 201 is a sheet having a smaller surface roughness than the left specific heat insulating material G1. The sheet 201 is made of nylon, for example, but is not limited to this. If the surface roughness of the left specific heat insulating material G1 is sufficiently small, the sheet 201 may be omitted.

Similarly, the right specific heat insulating material G2 has a recess 202 into which the right end portion of the vacuum heat insulating material 130 is inserted. That is, the right specific heat insulating material G2 has a shape of holding the right end portion of the vacuum heat insulating material 130 from the right side and the front and rear three directions. A flexible sheet 201 is sandwiched between the recess 202 of the right specific heat insulating material G2 and the right end of the vacuum heat insulating material 130. The sheet 201 has a smaller surface roughness than the right specific heat insulating material G2. When the surface roughness of the right specific heat insulating material G2 is sufficiently small, the sheet 201 may be omitted.

In the present embodiment, the left specific heat insulating material G1 and the right specific heat insulating material G2 are attached to the vacuum heat insulating material 130 before the vacuum heat insulating material 130 is installed in the frame 51. For example, in the vacuum heat insulating material 130, the left specific heat insulating material G1 and the right specific heat insulating material G2 are attached before the rear surface member 53 is attached to the frame body 51. The vacuum heat insulating material 130 is attached to the rear surface member 53 (or the frame body 51) by the left specific heat insulating material G1 and the right specific heat insulating material G2, so that the left heat insulating material G1 and the right specific heat insulating material G2 are integrated into the rear surface. It is attached to the member 53 (or the frame body 51). After that, the rear surface member 53 is attached to the frame body 51. As a result, it is possible to position the vacuum heat insulating material 130 in the horizontal width direction while reducing the possibility that the outer wall of the vacuum heat insulating material 130 will be damaged (for example, the possibility that the end portion of the outer heat insulating body in the horizontal width direction will be damaged). it can.
