As shown in FIG. 5 , when the door 2 is closed by the user and the housing 1 is pushed by the door 2 via the gasket 3 , the gasket 3 contacts the housing 1 at the contact portion 34 . The gap between the door 2 and the housing 1 is closed by contacting the opening edge 1a on the front surface of the . When the door 2 is closed by the user, the gasket 3 is sandwiched between the housing 1 and the door 2 pushed by the user. Frictional force is acting between the housing 1 and the floor according to its own weight. Y direction) is applied. Therefore, the bellows portion 35 is deformed so as to shrink in the depth direction (the arrow Y direction), and the gasket 3 is compressed. When the bellows portion 35 is deformed to shrink in the depth direction, the distance between the contact portion 34 and the outer plate back surface portion 21c is shortened, and the fin tip portion 36c of the fin portion 36 extending from the contact portion 34 moves toward the outer plate back surface portion 21c. Get closer. At this time, the fin portion 36 slides on the curved surface of the cover tip portion 33b while the fin inner surface 36b of the fin tip portion 36c and the outer surface of the cover tip portion 33b are in contact with each other. Therefore, even when the door 2 is closed by the user and the gasket 3 is compressed by an external force, the state in which the air layer 8 is formed inside the gasket 3 can be maintained.

Further, as described above, since the front end portion 33b of the cover is located closer to the outside space 7 than the bellows portion 35, when the bellows portion 35 shrinks due to an external force, the fin portion 36 moves along the curved surface of the front end portion 33b of the cover. When sliding, the bellows portion 35 can be prevented from colliding with the fin portion 36. - 特許庁Therefore, even when the bellows portion 35 is contracted by an external force, the fin portion 36 can maintain the air layer 8 without interfering with the movement of the bellows portion 35 .

After the door 2 is closed, when the external force is no longer applied to the gasket 3, the bellows portion 35 elastically stretches and returns to its original shape. 4 with the door 2 closed. When the bellows portion 35 is elastically stretched and returns to its original shape, the fins are extended while the fin inner surface 36b of the fin tip portion 36c and the outer surface of the cover tip portion 33b are in contact with each other in the same manner as when the bellows portion 35 is contracted by an external force. The portion 36 slides on the curved surface of the cover tip portion 33b. Therefore, even when the external force on the gasket 3 disappears after the door 2 is closed, the state in which the air layer 8 is formed inside the gasket 3 can be maintained.

When the door 2 is open, the gasket 3 attached to the door 2 is not in contact with the housing 1, and no external force is applied to the bellows portion 35 of the gasket 3. The positional relationship among the housing 1, the door 2, and the gasket 3 when the door 2 is open is the same as the positional relationship when the door 2 is closed shown in FIG.

By the way, the door 2 is warped or twisted, and depending on the warped or twisted shape of the door 2, the gasket 3 may partially deform unevenly when the door 2 is closed. For example, the back surface 20 on the left side of the door 2 is warped, and when the door 2 is closed, the gasket 3 provided on the back surface 20 on the left side of the door 2 is only in the center in the vertical direction (direction of arrow Z). A force that compresses the gasket 3 may be applied. Even when the door 2 is deformed in this way, the gasket 3 can maintain the state in which the air layer 8 is formed in the vertical direction (the direction of the arrow Z) when the door 2 is closed. Thermal insulation between the inside and the space 7 outside the chamber can be ensured.

Each side of the door 2 is provided with a gasket 3 having the same configuration as the above-described gasket 3 provided on the left side of the door 2 . The gasket 3 may be provided on at least one of the upper, lower, right, and left sides of the door 2 . For example, the above-described gaskets 3 are provided on both sides in the width direction (arrow Y direction) of the door 2, ie, the left side and the right side, which are visible to the user, and the fins 36 are provided on the other sides, ie, the upper side and the lower side. It is possible to provide a gasket 3 which is not closed. Further, when the band-shaped gasket 3 described above is provided along the outer periphery of the back surface of the door 2, the gasket 3 on each side can be connected to form a single frame-shaped gasket 3.

In addition, although the case where the inside wall portion 35b of the bellows portion 35 of the gasket 3 has a two-layer structure consisting of two wall portions has been described, the inside wall portion 35b can be formed by one wall portion. 2, the case where the gasket 3 has the extending portion 37 and the bag-like portion 38 has been described, but the extending portion 37 and the bag-like portion 38 can be omitted.

As described above, the refrigerator 100 of Embodiment 1 includes the housing 1 in which the storage chamber 6 is formed, the door 2 provided on the front surface of the housing 1 for opening and closing the storage chamber 6, and the housing 1 and a gasket 3 closing a gap between the door 2 and the door 2.例文帳に追加The gasket 3 is attached to the rear surface 20 of the door 2 and contacts the housing 1 when the door 2 is closed. The gasket 3 includes a gasket base portion 30 provided with a fitting portion 32 that is fitted to the back surface 20 of the door 2, and the gasket base portion 30 extends toward the outside space 7 along the back surface 20 of the door 2. and a cover portion 33 that covers a part of the The gasket 3 connects the contact portion 34 that contacts the housing 1 when the door 2 is closed, the contact portion 34, the gasket base portion 30, and the cover portion 33, and expands and contracts by an external force. and a portion 35 (3c). The gasket 3 has a fin portion 36 which is arranged closer to the outside space 7 than the bellows portion 35 and covers the outside space 7 side of the bellows portion 35 between the contact portion 34 and the cover portion 33 . The fin portion 36 is connected to one of the contact portion 34 and the cover portion 33 and contacts the other. An air layer 8 surrounded by the bellows portion 35 , the cover portion 33 , the fin portion 36 and the contact portion 34 is formed in the gasket 3 on the side of the outside space 7 from the bellows portion 35 .

As a result, the air layer 8 formed in the gasket 3 closer to the outside space 7 than the bellows portion 35 is surrounded by the bellows portion 35, the cover portion 33, the fin portion 36, and the contact portion 34. 8 does not contact the housing 1. Therefore, compared to the conventional configuration in which a space is formed between the bellows and fins of the gasket and the opening edge of the housing, the transmission of cold heat to the housing 1 through the space is suppressed, and the refrigerator can be The thermal insulation performance of 100 can be improved. Furthermore, the energy saving of the refrigerator 100 can be achieved by improving the heat insulation performance of the refrigerator 100 .

Also, the fin portion 36 has a flat plate shape. As a result, the fins 36 can slide easily on the contacting portion 34 or the cover portion 33 in contact therewith, and the movement of the bellows portion 35 is not hindered when the bellows portion 35 expands and contracts. In addition, since the user can see the flat fin outer surface 36a of the fin portion 36 and cannot see the curved bellows portion 35, the design of the refrigerator 100 is better than when the gasket 3 is not provided with the fin portion 36. can be improved. In addition, when cleaning the gasket 3, the user only needs to clean the flat plate-shaped fins 36, which makes cleaning easier than when the gasket 3 is not provided with the fins 36. Moreover, the expanding and contracting bellows part is sufficient. 35 can be avoided from being damaged by cleaning.

The cover part 33 has a tip part (cover tip part 33b) bent toward the back surface 20 of the door 2.例文帳に追加The fin portion 36 and the contact portion 34 are connected, the fin portion 36 is in contact with the cover tip portion 33b, and when the bellows portion 35 is contracted by an external force, the fin portion 36 slides on the curved surface of the cover tip portion 33b. It is configured.

As a result, when the bellows portion 35 contracts and when the shrunk bellows portion 35 expands and returns to its original shape, the fin portion 36 slides on the curved surface of the cover tip portion 33b while being in contact with the cover tip portion 33b. do. Therefore, not only when the door 2 is closed, but also when the user closes the door 2, or when the door 2 is warped or otherwise deformed, the gasket 3 partially deforms unevenly. Even in this case, the air layer 8 can be maintained within the gasket 3 .

In addition, the front end of the cover portion 33 (cover front end portion 33b) is located closer to the outside space 7 than the bellows portion 35 is. The fins 36 are inclined with respect to the virtual perpendicular line Lp of the rear surface 20 of the door 2 so that the cover 33 side of the fins 36 is positioned closer to the outside space 7 than the contact portion 34 side of the fins 36 is. ing.

This can prevent the bellows portion 35 from colliding with the fins 36 when the bellows portion 35 is shrunk by an external force and the fins 36 slide on the curved surface of the cover tip portion 33b. Therefore, even when the bellows portion 35 is contracted by an external force, the fin portion 36 can maintain the air layer 8 without interfering with the movement of the bellows portion 35 .

In addition, the door 2 is connected to a door outer plate 21 forming part of the front surface, the side surface, and the rear surface of the door 2, and the end portion 21c1 of the door outer plate 21 on the rear side of the door 2, and is connected together with the door outer plate 21. and a door inner plate 22 forming the back surface 20 of the door 2 . The cover portion 33 of the gasket 3 covers the portion of the inner door plate 22 that is connected to the end portion 21c1 of the outer door plate 21 (the end portion 22a1 of the inner door plate 22 on the side of the external space 7). The tip of the portion 33 contacts the door skin 21 .

As a result, cold air leakage through the gap between the gasket 3 and the door 2 can be suppressed, and the design of the refrigerator 100 can be improved by making the connecting portion between the door outer plate 21 and the door inner plate 22 invisible to the user. can be made

Further, the door 2 has a square shape when viewed from the front, and the gasket 3 is provided on at least one of the four sides of the door 2 . This suppresses the transmission of cold heat to the housing 1 on at least one side of the door 2 .

The refrigerator 100 also has a magnet 9, a storage space is formed in the contact portion 34, and the magnet 9 is stored in the storage space. As a result, the gasket 3 and the front opening edge portion 1a of the housing 1 can be brought into close contact with each other, and cold air leakage through the gap between the gasket 3 and the housing 1 can be suppressed.

Embodiment 2.
FIG. 6 is a cross-sectional view showing the positional relationship among housing 1, door 2, and gasket 3 when gasket 3 shrinks in refrigerator 100 according to the second embodiment. Refrigerator 100 of Embodiment 2 differs from that of Embodiment 1 in the configuration of fin portion 136 of gasket 3 , and the other configurations are the same as those of Embodiment 1. FIG.

Also in the second embodiment, similarly to the first embodiment, the fin portion 136 has a flat plate shape. A fin outer surface 136a of the fin portion 136 on the outside space 7 side and a fin inner surface 136b of the fin portion 36 on the bellows portion 35 side are substantially flat surfaces.

In the gasket 3 of Embodiment 2, the fin portion 136 is integrally formed with the cover portion 33, and the fin portion 136 and the cover portion 33 are connected. Specifically, the base 136d of the fin portion 136 is connected to the cover tip portion 33b of the cover portion 33, and the fin portion 136 and the cover tip portion 33b have a continuous flat plate shape. The fin portion 136 extends rearward and inside the refrigerator so as to face the outer surface 34a of the contact portion 34 from the front end portion 33b of the cover.

In the second embodiment, as in the case of the first embodiment, the fins 136 are arranged so that the cover 33 side of the fins 136 is positioned closer to the outside space 7 than the contact portion 34 side of the fins 136 . , with respect to an imaginary perpendicular line Lp perpendicular to the back surface 20 of the door 2 .

Further, in the gasket 3 of Embodiment 2, the fin portion 136 is not connected to the contact portion 34 . A fin tip portion 136c of the fin portion 136 is in contact with an outer surface 34a of the contact portion 34 located closest to the outside space 7 side. Specifically, the fin portion 136 and the contact portion 34 are in contact with each other such that the fin inner surface 136b of the fin tip portion 136c and the outer surface 34a of the contact portion 34 are in contact with each other. In the fin portion 136, a fin tip portion 136c that contacts the outer side surface 34a of the contact portion 34 is bent toward the outside space 7 side.

Next, the positional relationship between the tip portion 136c of the fin and the contact portion 34 and the operation of the gasket 3 will be described.

When the door 2 is closed and the user is not touching the door 2, the gasket 3 attached to the door 2 contacts the opening edge 1a on the front surface of the housing 1 at the contact portion 34. , closes the gap between the door 2 and the housing 1.例文帳に追加At this time, the fin portion 136 connected to the cover tip portion 33b is in contact with the contact portion 34 so that the fin inner surface 136b of the fin tip portion 136c and the outer surface 34a of the contact portion 34 are in contact with each other. Therefore, inside the gasket 3, an air layer 8 surrounded by the bellows portion 35, the contact portion 34, the cover portion 33, and the fin portion 36 is formed on the outside space 7 side of the bellows portion 35. - 特許庁Also in the refrigerator 100 of the second embodiment, as in the case of the first embodiment, the air layer 8 is formed on the outside space 7 side inside the gasket 3. Therefore, as in the case of the first embodiment, The effect of improving heat insulation performance is obtained.

Further, as shown in FIG. 6, when the door 2 is closed by the user and the housing 1 is pushed by the door 2 via the gasket 3, the gasket 3 is in contact with the housing at the contact portion . The gap between the door 2 and the housing 1 is closed by coming into contact with the opening edge 1 a on the front surface of the body 1 . When the door 2 is closed by the user, the bellows portion 35 is deformed so as to shrink in the depth direction (arrow Y direction), and the gasket 3 is compressed. When the bellows portion 35 is deformed so as to shrink in the depth direction, the distance between the contact portion 34 and the outer plate back surface portion 21c is shortened. At this time, the fin tip portion 136c slides on the outer surface 34a while the fin inner surface 136b of the fin tip portion 136c and the outer surface 34a of the contact portion 34 are in contact with each other. Therefore, even when the door 2 is closed by the user and the gasket 3 is compressed by an external force, the state in which the air layer 8 is formed inside the gasket 3 can be maintained.

As described above, in the refrigerator 100 of Embodiment 2, the cover portion 33 of the gasket 3 has a tip portion (cover tip portion 33b) bent toward the back surface 20 of the door 2. As shown in FIG. The fin portion 136 and the cover tip portion 33b are connected to each other, and the fin portion 136 is in contact with the outer surface 34a of the contact portion 34 located closest to the outside space 7 side. The fin portion 136 is configured to slide on the outer surface of the contact portion 34 when the bellows portion 35 is contracted by an external force.

As a result, when the bellows portion 35 shrinks, and when the shrunk bellows portion 35 expands and returns to its original shape, the fin portion 136 slides on the outer surface 34a while being in contact with the outer surface 34a of the contact portion 34. do. Therefore, not only when the door 2 is closed, but also when the user closes the door 2, or when the door 2 is warped or otherwise deformed, the gasket 3 partially deforms unevenly. Even in this case, the air layer 8 can be maintained within the gasket 3 .

The shapes of the housing 1, the door 2, and the gasket 3 are not particularly limited to those described above. FIG. 7 is a cross-sectional view showing a modification of refrigerator 100 according to the second embodiment. In the modification of Embodiment 2 shown in FIG. 7, the door outer plate 121 and the door inner plate are connected without a step, and the cover portion 133 of the gasket 3 extends from the fitting portion cover 31 side to the tip of the outer side of the cabinet. , is flat. The cover portion 33 is connected to the outer end of the fitting portion cover 31 , and the front surface of the cover portion 133 is connected to the rear surface of the door 2 from the fitting portion cover 31 side to the tip of the outer side of the refrigerator. It is in contact with the rear surface at 20 . A base 136d of the fin portion 136 is connected to the cover tip portion 133b of the cover portion 133, and the fin portion 136 extends rearward and inside the refrigerator from the cover tip portion 133b toward the outer surface 34a of the contact portion 34. is doing.

Also in the modification of the second embodiment, similarly to the case of the refrigerator 100 shown in FIG. 136 slides on the outer surface 34a of the contact portion 34 while contacting the outer surface 34a. Therefore, in the second modification of the second embodiment, as in the case of the refrigerator 100 shown in FIG. 6, the air layer 8 can be maintained in the gasket 3 even when the gasket 3 is partially deformed unevenly. You can get the effect that you can.

In the refrigerator 100 of FIG. 6 provided with the door 2 in which the outer door plate 21 and the inner door plate 22 are overlapped and connected to each other in the front-rear direction, the outer end surface of the inner door plate 22 is covered with the cover portion 133 . It may be exposed to the outside space 7 without breaking. That is, the door 2 shown in FIG. 6 may be provided with the gasket 3 shown in FIG. 7 in which the entire cover portion 133 is flat. In this case, the front surface of the cover portion 133 and the rear surface of the inner plate outer peripheral portion 22a are in contact with each other.

Embodiment 3.
FIG. 8 is a cross-sectional view showing the positional relationship among housing 1, door 2, and gasket 3 when gasket 3 shrinks in refrigerator 100 according to Embodiment 3. As shown in FIG. In the refrigerator 100 of the third embodiment, the shape of the fin tip portion 36c of the fin portion 36 of the gasket 3 is different from that of the first embodiment, and the rest of the configuration is the same as that of the first embodiment.

As described with reference to FIG. 5, when the bellows portion 35 is deformed so as to shrink in the depth direction, the distance between the contact portion 34 and the outer plate back surface portion 21c is shortened, and the fin portion 36 extending from the contact portion 34 is deformed. The fin tip portion 36c approaches the outer plate back surface portion 21c. Here, when the gasket 3 is compressed, the distance between the fin tip portion 36c and the outer plate back surface portion 21c changes according to the force with which the door 2 is pushed. In this case, the fin tip portion 36c comes into contact with the outer plate back surface portion 21c. As in the gasket 3 of Embodiment 1, in the configuration in which the fin tip portion 36c has a flat plate shape, when the door 2 is pushed with a force greater than a certain level, the corners of the tip of the fin portion 36 are pushed into the outer plate back surface portion 21c. may come into contact with and get caught. If the movement of the tip of the fin portion 36 is hindered, the fin portion 36 may bend toward the bellows portion 35 and the movement of the bellows portion 35 may be hindered.

Therefore, in Embodiment 3, a bent portion 36c1 is formed on the tip end side of the fin tip portion 36c so as to be convex toward the rear surface 20 side of the door 2, that is, forward.

When the door 2 is pushed with a force greater than a certain level, for example, when the user closes the door 2 with a strong force, the bent portion 36c1 of the fin portion 36 of the gasket 3 abuts against the outer panel rear portion 21c of the door 2. Meanwhile, the bent portion 36c1 of the fin portion 36 slides on the outer plate back portion 21c.

As described above, in the refrigerator 100 of Embodiment 3, the tip of the fin portion 36 is formed with a bent portion 36c1 that is bent so as to protrude toward the back surface 20 of the door 2 . As a result, even if the door 2 is pushed with a certain amount of force or more, for example, when the user closes the door 2 with a strong force, the bellows portion 35 is greatly deformed. The bent portion 36c1 of the portion 36 slides, and the tip portion 36c of the fin moves smoothly. Therefore, even when the door 2 is pushed with a certain force or more, the fins 36 are not bent toward the bellows part 35 side, and the fins 36 can prevent the movement of the bellows part 35 from being hindered.

When the door 2 is pushed with a certain amount of force or more, the fins 36 are separated from the cover 33. Therefore, an air layer surrounded by the bellows 35, the contact portion 34, the cover 33, and the fins 36 is formed. 8 is not formed. However, since the space surrounded by the bellows portion 35, the contact portion 34, the cover portion 33, the fin portion 36, and the outer plate back surface portion 21c is formed, airtightness is maintained.

It should be noted that it is possible to combine each embodiment, and to modify or omit each embodiment as appropriate. For example, in Embodiments 1 to 3, the case where the gasket 3 is provided on the rotating door 2 has been described, but the configuration of the door 2 on which the gasket 3 is provided is not limited to this. For example, the door 2, which is a sliding door, may be provided with the gasket 3.

Further, in Embodiments 1 to 3, the groove 22b is formed in the rear surface of the door 2, and the fitting portion 32, which is a protrusion, is formed in the gasket 3, and the fitting portion 32 of the gasket 3 is formed in the groove 22b of the door 2. The gasket 3 is fixed to the rear surface of the door 2 by being fitted. However, the fixing structure is not limited to the one described above as long as the gasket 3 is fixed to the rear surface of the door 2 . For example, a protrusion may be formed on the rear surface of the door 2 instead of the groove 22b, and a groove protruding into the space inside the bellows portion 35 may be formed on the gasket base 30 as the fitting portion 32 .
