The side sealing member 50 has a length similar to that of the side surface of the heat insulation door main body 12, and has a predetermined width. The side sealing member 50 is attached to the side surface of the heat insulation door main body 12 so as to extend in the vertical direction along the vertical direction of the heat insulation door 4.

When the pair of heat insulation doors 4 of the refrigerator 1 is closed, the side surface sealing members 50 of the heat insulation door bodies 12 are brought into close contact with each other, whereby the side surfaces of the heat insulation doors 4 are sealed.

Next, the rear surface of the heat insulation door main body 12 will be described in detail.

As shown in fig. 2, the outer edge of the rear surface of the heat insulating door main body 12 has an upper surface side, a lower surface side, and side surface sides formed by the end portions of the door outer panel 13, and a rear surface center portion side formed by the end portions of the door inner panel 14.

An outer edge attachment groove 16 is provided around the entire periphery of an end portion of the door inner panel 14, that is, an outer edge of the rear surface of the heat insulation door main body 12. The width of the outer edge attachment groove 16 is formed so that the vicinity of the opening portion is narrow and the portion located on the front surface side of the heat insulating door main body 12 is wide when viewed in a cross section in the width direction. That is, the outer edge mounting groove 16 is formed in a so-called ant groove shape. A plurality of outer edge seal members 20 are mounted in the outer edge mounting groove 16.

Fig. 5 is a cross-sectional view of the outer edge seal member 20 in the width direction.

The plurality of outer edge sealing members 20 are sealing members such as gaskets or washers made of a soft resin such as rubber or soft polyvinyl chloride. These outer edge sealing members 20 are formed in a linear shape so as to correspond to the respective sides of the outer edge of the heat insulation door main body 12.

Each of the outer edge seal members 20 includes a seal member main body 28, an outer edge mounting portion 30, a first inner fin portion 31, a second inner fin portion 32, a third inner fin portion 33, and a pair of outer fin portions 35.

The seal member body 28 is formed in a hollow cylindrical shape having a substantially rectangular cross section, and the interior of the seal member body 28 is divided into a plurality of spaces.

Specifically, the sealing member body 28 is composed of a front panel 28A disposed on the storage container 2 side, a back panel 28B disposed on the heat insulation door body 12 side, an outer side panel 28C disposed apart from the opening 2B, and an inner side panel 28D disposed on the opening 2B side.

The thickness dimensions of the front panel 28A, the exterior side panel 28C, and the interior side panel 28D are all formed to be substantially the same thickness, and the thickness dimension of the back panel 28B is formed to be thicker than the thickness dimensions of the front panel 28A, the exterior side panel 28C, and the interior side panel 28D.

An outer edge magnet housing portion 21 having a rectangular cross section is provided at a corner portion of the seal member main body 28 formed by the front panel 28A and the outside side panel 28C. The outer edge magnet housing portion 21 is formed to be hollow, and a rod-shaped outer edge magnet 40 is housed inside the outer edge magnet housing portion 21. The outer edge magnets 40 have the same length as the respective edges of the rear surface of the heat insulation door main body 12, and are inserted through the respective outer edge magnet receiving portions 21 along the respective edges.

The storage 2 side of the outer edge magnet housing part 21 is constituted by a housing front panel 21A. The outer surface of the housing front panel 21A is formed as a contact surface 22 formed as a smooth flat surface over the entire length of the outer edge seal member 20.

Further, in the peripheral magnet housing portion 21, a portion located on the opposite side of the housing portion front plate 21A with the peripheral magnet 40 interposed therebetween is constituted by a housing portion back plate 21B. A first partition 24 is connected to a connection surface 23, which is an outer surface of the housing back plate 21B.

The first partition portion 24 is formed integrally with the seal member body 28 and partitions the space inside the seal member body 28. First partition 24 protrudes from connection surface 23 toward back panel 28B, extends along back panel 28B toward inner side panel 28D, is bent into a substantially U-shape, and is connected to front panel 28A.

Thus, a first central space S1 is provided inside the seal member main body 28, and the first central space S1 is surrounded by the first partition 24, the front panel 28A, and the outer edge magnet housing 21.

Further, the first partition 24 has substantially the same thickness dimension as the front panel 28A.

A second partition 25 and a third partition 26 extending toward the back panel 28B are connected to intermediate portions of the first partition 24. These second and

third partitions

25 and 26 are integrally molded with the seal member main body 28, similarly to the first partition 24. Both the second partition 25 and the third partition 26 are connected to the back panel 28B with a predetermined gap therebetween. The second partition 25 has substantially the same thickness as the front panel 28A, and the third partition 26 has substantially the same thickness as the back panel 28B.

Inside the seal member main body 28, an outside space S2 surrounded by the second partition 25, the first partition 24, the outside side plate 28C, the connection surface 23, and the back plate 28B is provided. Further, an inner space S3 surrounded by the third partition 26, the first partition 24, the inner side plate 28D, the front plate 28A, and the back plate 28B is provided inside the seal member body 28. A second central space S4 surrounded by the first partition 24, the second partition 25, the third partition 26, and the back panel 28B is provided inside the outer edge seal member 20.

The rear plate 28B of the seal member body 28 is provided with an outer edge attachment portion 30 over the entire length of the outer edge seal member 20. The outer edge attachment portion 30 is provided to protrude from the rear plate 28B of the seal member body 28. The outer edge attachment portion 30 is formed to be tapered toward the projecting distal end side from the sealing member main body 28 side when viewed in a cross section of the sealing member main body 28 in the width direction.

A pair of return portions 30A each extending toward the sealing member main body 28 are provided near the tip of the outer edge mounting portion 30. The pair of return portions 30A is formed in a V shape when viewed in a cross section of the seal member body 28 in the width direction, and each return portion 30A extends to both sides across the outer edge mounting portion 30.

Therefore, the outer edge mounting portion 30 and the pair of return portions 30A provided at the distal ends thereof form an arrow shape of the present invention as viewed in a cross section in the width direction of the seal member body 28.

Outer edge mounting portion 30 is formed to be hollow and has substantially the same thickness as rear plate 28B.

The third partition 26 is connected to the center of the rear surface of the outer edge mounting portion 30. The third partition portion 26 connects the back surface of the outer edge mounting portion 30 and the first partition portion 24, and the third partition portion 26 is connected to the back surface of the outer edge mounting portion 30 in a state of extending in substantially the same direction as the direction in which the outer edge mounting portion 30 protrudes.

The first inner fin portion 31, the second inner fin portion 32, and the third inner fin portion 33 are provided at a corner portion of the sealing member main body 28 formed by the front panel 28A and the inner side panel 28D. The first inner fin portion 31, the second inner fin portion 32, and the third inner fin portion 33 are each formed into a thin plate shape having flexibility with a free end on the distal end side, and protrude toward the storage 2 so as to be in contact with the door inner panel 14 of the heat insulating door main body 12.

The first inner fin 31 has a predetermined thickness and is formed to be hollow.

Specifically, the first inner fin portion 31 includes a thick portion 34, and the thick portion 34 is formed thick from the front panel 28A of the sealing member main body 28 to the middle in the width direction. The thick portion 34 is formed to be hollow, and two hollow portions V1, V2 are provided inside the thick portion 34.

As shown in fig. 2, the thick portion 34 abuts against the side member 9 of the storage 2 in a state where the heat insulating door 4 is closed.

Therefore, the first inner fin portion 31 seals the space between the side member 9 and the door panel 14, and the hollow portions V1, V2 inside the thick portion 34 function as heat insulating air layers, thereby suppressing leakage of cold air from the storage compartment 2A.

Each space surrounded by the first inner fin portion 31, the second inner fin portion 32, the third inner fin portion 33, and the door inner panel 14 also functions as a heat insulating air layer, and thus cold air leakage from the storage compartment 2A is suppressed. That is, the first inner fin portion 31, the second inner fin portion 32, and the third inner fin portion 33 seal the space between the storage 2 and the heat insulating doors 4, thereby improving the sealing performance between the storage 2 and the heat insulating doors 4.

A pair of outer fin portions 35 are provided at the corner portions formed by the back panel 28B and the outer side panel 28C of the seal member main body 28.

Each of the outer fin portions 35 protrudes toward the outer edge of the rear surface of the heat insulation door main body 12, and abuts against the door outer panel 13 of the heat insulation door main body 12.

Since these external fin portions 35 are provided, it is possible to suppress the intrusion of dust into the storage compartment 2A from the outside of the storage 2, the propagation of mold, and the like.

Further, the space surrounded by the outer fin portions 35 and the door outer panel 13 functions as an insulating air layer, and prevents the cold air in the storage compartment 2A from leaking between the outer edge seal member 20 and the heat insulating door main body 12.

The hollow thick portions are not limited to the first inner fin portion 31, but may be provided in the second inner fin portion 32, the third inner fin portion 33, and the outer fin portion 35.

Next, the operation of the present embodiment will be explained.

First, a procedure of attaching the outer edge sealing member 20 to the heat insulation door main body 12 will be described.

When the outer edge sealing member 20 is attached, the front panel 28A of the sealing member main body 28 is pressed with the outer edge attachment portion 30 in contact with the outer edge attachment groove 16. At this time, the third partitioning portion 26 is pressed toward the tip of the outer edge mounting portion 30. Since the outer edge mounting portion 30 is formed to be hollow, the back surface of the outer edge mounting portion 30 is bent, and the side surfaces of the outer edge mounting portion 30 are deformed in the direction of approaching each other. Further, each return portion 30A is also deformed similarly, and the width of the outer edge attachment portion 30 is deformed to be narrow. Therefore, the outer edge mounting part 30 can be easily inserted into the outer edge mounting groove 16, and the mounting property of the outer edge sealing member 20 can be improved.

In this way, the outer edge seal member 20 is mounted to the door outer panel 13 by inserting the outer edge mounting portion 30 into the outer edge mounting groove 16. At this time, each returning portion 30A is again expanded in the width direction and engaged with the opening of the outer edge mounting groove 16. Thus, the returning portions 30A function as a stopper, and the outer edge sealing member 20 is reliably fixed to the heat insulation door main body 12.

Fig. 6 is a cross-sectional view of the outer edge sealing member 20 in the width direction in a state of being in close contact with the storage 2.

When the heat insulating door 4 is closed, the metal plate 10 and the outer edge magnet 40 provided in each outer edge sealing member 20 are attracted to each other by magnetic force, and as shown in fig. 6, the outer edge magnet housing portion 21 is pulled toward the storage 2. Further, since the back surface plate 28B of the seal member body 28 is fixed to the heat insulation door body 12 by the outer edge attachment portion 30, the outer side plate 28C and the front surface plate 28A of the seal member body 28 are pulled toward the storage container 2 side together with the outer edge magnet housing portion 21, and the seal member body 28 is deformed.

At this time, the first partition portion 24 is extended, and thereby the contact surface 22 of the outer edge magnet housing portion 21 moves in parallel with the surface of the metal plate 10. Therefore, the entire surface of the contact surface 22 is in contact with the surface of the metal plate 10. Therefore, when the heat insulating door 4 is closed, the outer edge sealing member 20 can be prevented from being peeled off from the metal plate 10, and the storage 2 and the heat insulating door 4 can be reliably sealed. Further, leakage of cold air in the storage chamber 2A can be suppressed.

Further, the occurrence of so-called co-opening can be suppressed: when one of the pair of insulated doors 4, i.e., the insulated door 4, is opened, the other insulated door 4 is opened.

In a state where the heat insulating door 4 is closed, as shown in fig. 2, the outer edge sealing members 20 are disposed between the storage 2 and the heat insulating door main body 12. Further, as described above, the first central space S1, the outer side space S2, the inner side space S3, and the second central space S4 are formed inside each outer edge seal member 20.

These first central space S1, outer space S2, inner space S3, and second central space S4 all function as heat insulating air layers, and can suppress the intrusion of heat into storage compartment 2A and the leakage of cold air from storage compartment 2A.

At least three spaces among the spaces formed inside the outer edge sealing members 20 are disposed between the storage 2 and the heat insulation door main body 12 and between the inside and the outside of the storage 2.

Specifically, the external seal member 20 is attached so that the first central space S1, the external space S2, the internal space S3, the external space S2, the internal space S3, and the second central space S4 are disposed between the inside and the outside of the storage container 2.

That is, at least three heat-insulating air layers are provided between the inside and the outside of the storage 2.

Therefore, between the storage 2 and the heat insulating door 4, leakage of cold air in the storage compartment 2A can be more reliably suppressed, and the power saving effect of the refrigerator 1 can be improved.

According to the above embodiment, the following effects are obtained.

The refrigerator 1 of the present embodiment includes a storage 2 provided with an opening and a pair of heat insulating doors 4 provided in the opening 2B. Each of the heat insulating doors 4 is provided with a plurality of outer edge sealing members 20 for sealing the opening 2B, and each of the sealing member bodies 28 of the outer edge sealing members 20 is formed hollow. Further, a first partition 24, a second partition 25, and a third partition 26 are provided inside the seal member main body 28. These first, second and

third partitions

24, 25 and 26 form a first central space S1, an outer lateral space S2, an inner lateral space S3 and a second central space S4. Further, the structure is as follows: at least three of these spaces are arranged between the inside and the outside of the storage 2.

Thereby, at least three heat insulating air layers are provided between the inside and the outside of the storage 2. Therefore, leakage of cold air in the storage compartment 2A can be more reliably suppressed between the storage compartment 2 and the heat insulating door 4.

Further, according to the present embodiment, the outer edge magnet housing portion 21 for housing the outer edge magnet 40 is provided in the seal member main body 28, and the housing front panel 21A of the outer edge magnet housing portion 21 is provided with the contact surface 22 which is in contact with the metal plate 10 of the storage 2. Further, the first separator 24 is configured to: the connection surface 23 is provided on the outer surface of the housing back surface plate 21B located on the opposite side of the housing front surface plate 21A with the peripheral magnet 40 interposed therebetween. Therefore, the close contact surface 22 can be moved parallel to the surface of the metal plate 10, and the entire surface of the close contact surface 22 can be reliably brought into close contact with the surface of the metal plate 10. Therefore, the outer edge seal member 20 can be prevented from peeling off from the metal plate 10.

Further, according to the present embodiment, the outer edge sealing member 20 is detachably attached to the heat insulating door main body 12 at the outer edge attachment portion 30 protruding from the outer edge sealing member 20, and the outer edge attachment portion 30 is formed in an arrow-like shape in cross section in the width direction. The third partition 26 is provided on the rear surface of the outer edge attachment portion 30. Therefore, when the outer edge sealing member 20 is attached to the heat insulation door main body 12, the third partitioning portion 26 is pushed toward the end of the outer edge attachment portion 30, and the returning portions 30A are deformed in the direction of approaching each other. Therefore, the outer edge mounting portion 30 can be easily inserted into the outer edge mounting groove 16, and the mounting property of the outer edge seal member 20 can be improved.

Further, according to the present embodiment, the outer edge sealing member 20 is provided with the first inner fin portion 31 for sealing between the storage 2 and the heat insulating door main body 12, and the first inner fin portion 31 is formed to have a hollow structure including the hollow portions V1 and V2. Therefore, the first inner fin portion 31 seals the space between the side member 9 and the door panel 14, and the hollow portions V1, V2 inside the thick portion 34 function as heat insulating air layers, thereby suppressing leakage of cold air in the storage compartment 2A.

The above-described embodiment exemplifies one aspect of the present invention, and can be arbitrarily modified and applied within a range not departing from the gist of the present invention.
