次に、本実施形態の作用について説明する。
まず、外縁封止部材２０を断熱扉本体１２に取り付ける手順について説明する。
外縁封止部材２０を取り付けるときには、外縁取付部３０を外縁取付溝１６に当接させた状態で、封止部材本体２８の前面板２８Ａが押圧される。このとき、第３仕切部２６は、外縁取付部３０の先端に向かって押し込まれる。外縁取付部３０は、中空に形成されているため、外縁取付部３０の背面がたわみ、当該外縁取付部３０の各側面が互いに接近する方向に変形する。そして、各返し部３０Ａも同様に変形し、外縁取付部３０の幅が狭く変形する。このため、外縁取付部３０を外縁取付溝１６に容易に挿入することができ、外縁封止部材２０の取付性を向上させることができる。 Next, the operation of this embodiment will be explained.
First, a procedure for attaching the outer edge sealing member 20 to the heat insulating door body 12 will be described.
When attaching the outer edge sealing member 20, the front plate 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 partition part 26 is pushed toward the tip of the outer edge attachment part 30. Since the outer edge attachment portion 30 is formed hollow, the back surface of the outer edge attachment portion 30 is bent, and each side surface of the outer edge attachment portion 30 is deformed in a direction in which they approach each other. Then, each return portion 30A is similarly deformed, and the width of the outer edge attachment portion 30 is deformed to become narrower. Therefore, the outer edge attachment portion 30 can be easily inserted into the outer edge attachment groove 16, and the ease of attaching the outer edge sealing member 20 can be improved.

このように、外縁取付部３０が外縁取付溝１６に挿入されることによって、外縁封止部材２０が扉外装板１３に取り付けられる。このとき、各返し部３０Ａは、幅方向に再び広がり、外縁取付溝１６の開口箇所に係合する。これによって、各返し部３０Ａが抜け止めとして作用し、外縁封止部材２０が断熱扉本体１２に確実に固定される。 In this manner, the outer edge sealing member 20 is attached to the door exterior plate 13 by inserting the outer edge attachment portion 30 into the outer edge attachment groove 16. At this time, each of the turned portions 30A widens again in the width direction and engages with the opening of the outer edge attachment groove 16. As a result, each return portion 30A acts as a retainer, and the outer edge sealing member 20 is reliably fixed to the heat insulating door body 12.

図６は、貯蔵庫２に密着した状態の外縁封止部材２０の幅方向における断面図である。
断熱扉４が閉止されると、金属板１０と、各外縁封止部材２０が備える外縁磁石４０とが磁力によって引き合い、図６に示すように、外縁磁石収容部２１が貯蔵庫２側に引っ張られる。また、封止部材本体２８の背面板２８Ｂは、外縁取付部３０によって断熱扉本体１２に固定されているため、封止部材本体２８の外部側側板２８Ｃと前面板２８Ａとが外縁磁石収容部２１と共に貯蔵庫２側に引っ張られ、封止部材本体２８が変形する。 FIG. 6 is a cross-sectional view in the width direction of the outer edge sealing member 20 in close contact with the storage 2. As shown in FIG.
When the heat insulating door 4 is closed, the metal plate 10 and the outer edge magnets 40 included in each outer edge sealing member 20 are attracted to each other by magnetic force, and the outer edge magnet accommodating portion 21 is pulled toward the storage 2 side, as shown in FIG. . Furthermore, since the back plate 28B of the sealing member main body 28 is fixed to the heat insulating door main body 12 by the outer edge attachment part 30, the outer side side plate 28C and the front plate 28A of the sealing member main body 28 are attached to the outer edge magnet accommodating part 21. At the same time, it is pulled toward the storage 2 side, and the sealing member main body 28 is deformed.

このとき、第１仕切部２４が伸長することによって、外縁磁石収容部２１の密着面２２は、金属板１０の表面に平行に移動される。これによって、密着面２２は、全面が金属板１０の表面に密着する。このため、断熱扉４が閉止されたときに、外縁封止部材２０が金属板１０から剥離することを抑制することができ、貯蔵庫２と断熱扉４との間を確実に封止することができる。そして、貯蔵室２Ａの冷気の漏洩を抑制することができる。
また、観音開き扉である一対の断熱扉４の内、一方の断熱扉４を開いたときに、他方の断熱扉４が開かれる、所謂共開きが生じることを抑制できる。 At this time, as the first partition part 24 expands, the contact surface 22 of the outer edge magnet housing part 21 is moved parallel to the surface of the metal plate 10. As a result, the entire surface of the contact surface 22 is brought into close 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 peeling off from the metal plate 10, and the space between the storage 2 and the heat insulating door 4 can be reliably sealed. can. And it is possible to suppress leakage of cold air from the storage room 2A.
Further, it is possible to suppress the occurrence of so-called co-opening, in which when one of the pair of heat-insulating doors 4, which are double-hinged doors, is opened, the other heat-insulating door 4 is opened.

断熱扉４が閉止された状態において、各外縁封止部材２０は、図２に示すように、貯蔵庫２と、断熱扉本体１２との間に配置されている。また、上述の通り、各外縁封止部材２０の内部には、第１中央空間Ｓ１と、外部側空間Ｓ２と、内部側空間Ｓ３と、第２中央空間Ｓ４とが形成されている。
これらの第１中央空間Ｓ１と、外部側空間Ｓ２と、内部側空間Ｓ３と、第２中央空間Ｓ４とは、いずれも断熱空気層として作用し、貯蔵室２Ａに熱が侵入することを抑制すると共に、貯蔵室２Ａから冷気が漏出することを抑制することができる。
さらに、貯蔵庫２と、断熱扉本体１２との間において、貯蔵庫２の内部と外部との間には、各外縁封止部材２０の内部に形成された各空間の内、少なくとも３つの空間が配置されている。
具体的には、外縁封止部材２０は、貯蔵庫２の内部と外部との間に、第１中央空間Ｓ１と、外部側空間Ｓ２と、内部側空間Ｓ３、または外部側空間Ｓ２と、内部側空間Ｓ３と、第２中央空間Ｓ４とが配置されるように取り付けられている。
すなわち、貯蔵庫２の内部と外部との間には、少なくとも３つの断熱空気層が設けられている。
これによって、貯蔵庫２と、断熱扉４との間において、より確実に貯蔵室２Ａの冷気の漏洩を抑制することができ、冷蔵庫１の節電効果を向上させることができる。 When the heat insulating door 4 is closed, each outer edge sealing member 20 is arranged between the storage 2 and the heat insulating door body 12, as shown in FIG. Furthermore, as described above, inside each outer edge sealing member 20, a first central space S1, an external space S2, an internal space S3, and a second central space S4 are formed.
These first central space S1, outer side space S2, inner side space S3, and second central space S4 all act as a heat insulating air layer and suppress heat from entering the storage room 2A. At the same time, leakage of cold air from the storage chamber 2A can be suppressed.
Furthermore, between the storage 2 and the heat insulating door body 12, at least three spaces are arranged between the inside and outside of the storage 2 among the spaces formed inside each outer edge sealing member 20. has been done.
Specifically, the outer edge sealing member 20 has a first central space S1, an outer space S2, an inner space S3, or an outer space S2, and an inner space between the inside and the outside of the storage 2. It is attached so that the space S3 and the second central space S4 are arranged.
That is, at least three heat-insulating air layers are provided between the inside and outside of the storage 2.
Thereby, leakage of cold air from the storage room 2A between the storage 2 and the heat insulating door 4 can be more reliably suppressed, and the power saving effect of the refrigerator 1 can be improved.

これによって、貯蔵庫２の内部と外部との間には、少なくとも３つの断熱空気層が設けられている。このため、貯蔵庫２と、断熱扉４との間において、より確実に貯蔵室２Ａの冷気の漏洩を抑制することができる。 The refrigerator 1 of this embodiment includes a storage 2 provided with an opening and a pair of heat insulating doors 4 provided in the opening 2B. Each of these heat-insulating doors 4 is provided with a plurality of outer edge sealing members 20 that seal the opening 2B, and each of the sealing member bodies 28 of these outer edge sealing members 20 is formed hollow. has been done. Further, inside the sealing member main body 28, a first partition part 24, a second partition part 25, and a third partition part 26 are provided.

The first partition 24 is provided on the connection surface 23, which is the outer surface of the housing back plate 21B, which is located on the opposite side of the housing front plate 21A with the outer edge magnet 40 interposed therebetween. Thereby, the contact surface 22 is moved parallel to the surface of the metal plate 10, and the entire surface can be reliably brought into close contact with the surface of the metal plate 10. Therefore, peeling of the outer edge sealing member 20 from the metal plate 10 can be suppressed.
