Description

本発明の実施形態は冷蔵庫に関する。 Embodiments of the present invention relate to refrigerators.

例えば家庭用の冷蔵庫においては、冷蔵庫本体の冷蔵室の前面の開口部を、観音開き式の扉により開閉するように構成されたものが知られている（例えば特許文献１参照）。この観音開き式の扉にあっては、左右の両扉の裏面の周縁部に、扉の閉塞時に冷蔵庫本体側との間の隙間を封止するためのガスケットが設けられる。これと共に、一方の扉（左扉）の、非枢支側（右辺側）の裏面側に、それらガスケットのうち、非枢支側の部分を受けるための縦仕切体が設けられる。この縦仕切体は、縦方向に延びる回転軸を中心に回動可能に取付けられ、左扉の開放時には、該左扉の右側面部に沿って邪魔にならない状態に位置され、左扉の閉塞時には、９０度回転してガスケットを受ける面を正面に向けるように構成されている。 For example, in a household refrigerator, it is known that the opening on the front surface of the refrigerator compartment of the refrigerator body is configured to be opened and closed by a double door (see, for example, Patent Document 1). In this double door, a gasket is provided on the peripheral edge of the back surface of both the left and right doors to seal the gap between the door and the refrigerator body when the door is closed. Along with this, on the back surface side of one door (left door) on the non-axial support side (right side side), a vertical partition body for receiving the non-axial support side portion of these gaskets is provided. This vertical partition is rotatably attached around a rotation axis extending in the vertical direction, and is positioned in an unobtrusive state along the right side surface of the left door when the left door is opened, and when the left door is closed. , 90 degrees rotated so that the surface receiving the gasket faces the front.

この場合、特許文献１においては、ガスケットの十分な吸着力を得るために、ガスケットの内部と、縦仕切体の内部との双方に磁石（磁性体）を設ける構成が採用されている。またこのとき、ガスケット側の吸着面の磁石を、例えば左右にＮ、Ｓの２極の磁極とすると共に、縦仕切体側の吸着面の磁石を、左右にＳ、Ｎの２極の磁極として、磁石同士の吸着がより確実に行われるようにしている。 In this case, Patent Document 1 employs a configuration in which magnets (magnetic materials) are provided both inside the gasket and inside the vertical partition in order to obtain a sufficient attractive force of the gasket. At this time, the magnet on the suction surface on the gasket side is, for example, two poles of N and S on the left and right, and the magnet on the suction surface on the vertical partition side is the two poles of S and N on the left and right. The magnets are attracted to each other more reliably.

特開２０１６−３８１１号公報Japanese Unexamined Patent Publication No. 2016-3811

上記のように、ガスケットと縦仕切体との双方に磁石を設ける構成を採用した場合、一方の吸着面のＳ極の位置と、他方の吸着面のＮ極の位置とが正しく対向していることが重要となる。ところが、各扉におけるガスケットの取付け位置のばらつき、冷蔵庫本体に対する扉の取付け位置のばらつき、縦仕切体における回転軸の位置のばらつき（ウレタン発泡時の発泡圧に起因する位置ずれ）等により、ガスケットと縦仕切体との間の磁石の位置に幅方向のずれが生ずることが考えられる。ガスケットと縦仕切体との間でそのような磁石の幅方向のずれが生じていると、例えばＮ極同士が対向して反発が生じる等、吸着力の低下を招いてしまう虞があり、ひいては、庫内からの冷気の漏れや、縦仕切体の露付き等の不具合を招いてしまうことになる。 As described above, when a configuration in which magnets are provided on both the gasket and the vertical partition is adopted, the position of the S pole on one suction surface and the position of the N pole on the other suction surface are correctly opposed to each other. Is important. However, due to variations in the mounting position of the gasket on each door, variations in the mounting position of the door with respect to the refrigerator body, variations in the position of the rotating shaft in the vertical partition (positional deviation due to foaming pressure during urethane foaming), etc. It is conceivable that the position of the magnet with the vertical partition is displaced in the width direction. If such a deviation of the magnet in the width direction occurs between the gasket and the vertical partition body, there is a risk that the attractive force may decrease, for example, the N poles face each other and repulsion occurs. , Leakage of cold air from the inside of the refrigerator and dew on the vertical partition will cause problems.

そこで、観音開き式の扉のガスケットと縦仕切体との双方に磁石を設けたものにあって、磁石の位置に多少の幅方向のずれがあっても、吸着力を確保することができる冷蔵庫を提供する。 Therefore, a refrigerator that has magnets on both the gasket of the double door and the vertical partition, and can secure the suction force even if the position of the magnets is slightly displaced in the width direction. provide.

実施形態の冷蔵庫は、冷蔵庫本体の開口部を開閉する観音開き式の左右の扉と、前記各扉の裏面周縁部に設けられ内部に磁石を収容したガスケットと、前記扉のうち一方の扉の非枢支側の裏面に縦方向に延びる回転軸を中心に回動可能に設けられ、前記両扉のガスケットのうち非枢支側の部分を受けるための縦仕切体と、前記縦仕切体に前記両扉の非枢支側のガスケットに対応して左右に位置して設けられ、前記各ガスケットを吸着するための磁石とを具備し、前記縦仕切体の磁石または前記ガスケットの磁石は吸着面におけるＮ極とＳ極の割合が異なる磁石であって、前記縦仕切体の磁石と前記ガスケットの磁石との対向する面のうち、異極同士が対向する部分の幅方向寸法が、同極同士が対向する部分の幅方向寸法よりも大きくなっていると共に、前記縦仕切体の各磁石又は前記各ガスケットの磁石の、少なくとも一方の磁極は、幅方向に３極が並ぶように構成されている。尚、ここでいう幅方向寸法とは、ゼロであること、つまり、他方の磁石の磁極がＮ極だけ又はＳ極だけの１極であることも含んでいる。 The refrigerator of the embodiment includes left and right doors that open and close the opening of the refrigerator body, a gasket that is provided on the peripheral edge of the back surface of each door and contains a magnet inside, and one of the doors is not. A vertical partition body that is rotatably provided on the back surface of the pivotal support side and is rotatably provided around a rotation axis extending in the vertical direction to receive a portion of the gaskets on both doors that is not on the pivotal support side, and the vertical partition body. The magnets of the vertical partition or the magnets of the gaskets are provided on the left and right positions corresponding to the gaskets on the non-axial side of both doors and are provided with magnets for attracting the respective gaskets. Magnets having different ratios of N pole and S pole, and the width direction dimensions of the portions of the facing surfaces of the magnet of the vertical partition and the magnet of the gasket where the different poles face each other are the same. The magnetic poles of at least one of the magnets of the vertical partition and the magnets of the gaskets are configured so as to have three poles arranged in the width direction, while being larger than the width dimension of the opposing portions. The width direction dimension referred to here also includes that it is zero, that is, the magnetic pole of the other magnet is only one pole having only N poles or only S poles.

Along with this, a cold air supply mechanism for supplying the cold air generated by the evaporator to the refrigerating chamber 3, the freezing chamber 4, and the vegetable compartment 5 is provided.

ここで、前記ガスケット８、９及び縦仕切体１２について、図３〜図５も参照して述べる。ガスケット８、９は、ゴム等の柔軟性を有する材料から、断面が、四角形（長方形）の中空状に構成されている。図３、図５に示すように、ガスケット８内の背面側、つまり縦仕切体１２との当接面側に、第１の磁石１０が収容されており、ガスケット９内の背面側、つまり縦仕切体１２との当接面側に、第２の磁石１１が収容されている。これら第１の磁石１０及び第２の磁石１１は、共に前後方向に薄型の断面長方形状をなしており、後述するように、その背面側が、所定の磁極となるように着磁されている。 Here, the gaskets 8 and 9 and the vertical partition body 12 will be described with reference to FIGS. 3 to 5. The gaskets 8 and 9 are made of a flexible material such as rubber, and have a hollow shape having a rectangular cross section. As shown in FIGS. 3 and 5, the first magnet 10 is housed on the back surface side in the gasket 8, that is, the contact surface side with the vertical partition body 12, and the back surface side in the gasket 9, that is, the vertical direction. A second magnet 11 is housed on the contact surface side with the partition body 12. Both the first magnet 10 and the second magnet 11 have a thin rectangular cross section in the front-rear direction, and as will be described later, the back surface side thereof is magnetized so as to have a predetermined magnetic pole.

前記縦仕切体１２は、図３、図４に示すように、全体として、断面が長方形状をなす上下方向に延びる角柱状をなしている。より具体的には、図３に示すように、縦仕切体１２は、合成樹脂製の外殻体２０内に、発泡断熱材２１を充填すると共に、吸着するための２個の磁石２２及び２３や、結露防止用のヒータ２４などを組込んで構成されている。この縦仕切体１２は、左扉６の非枢支側である右側辺部の背面側に、支持部１９により縦方向に延びる回動軸Ｏを中心に回動可能に支持されている。 As shown in FIGS. 3 and 4, the vertical partition body 12 has a rectangular columnar shape extending in the vertical direction having a rectangular cross section as a whole. More specifically, as shown in FIG. 3, in the vertical partition body 12, the outer shell body 20 made of synthetic resin is filled with the foamed heat insulating material 21, and the two magnets 22 and 23 for adsorbing the foam heat insulating material 21. It is configured by incorporating a heater 24 for preventing dew condensation and the like. The vertical partition body 12 is rotatably supported by a support portion 19 on the back side of the right side portion of the left door 6 which is a non-axial support side, about a rotation shaft O extending in the vertical direction.

このとき、縦仕切体１２は、図４（ａ）に示すような、左扉６の側面部に沿うように配置される退避位置と、図４（ｂ）に示すような、左扉６のガスケット８の右側辺部、及び、右扉７のガスケット９の左側辺部を受ける状態となる作用位置との間で回動される。詳しく図示はしないが、縦仕切体１２は、ばね力によって、退避位置側に常時付勢されている。そして、縦仕切体１２の上下両端面部には、カム溝が形成されていると共に、冷蔵室３の開口部の上下部には、カム溝を相対的に移動することによって、縦仕切体１２を作用位置に回動させるための突起部２５、２６（図２参照）が設けられている。 At this time, the vertical partition body 12 has a retracted position arranged along the side surface portion of the left door 6 as shown in FIG. 4A and a retracted position of the left door 6 as shown in FIG. 4B. It is rotated between the right side of the gasket 8 and the working position where the left side of the gasket 9 of the right door 7 is received. Although not shown in detail, the vertical partition body 12 is constantly urged toward the retracted position by a spring force. A cam groove is formed on both upper and lower end surfaces of the vertical partition body 12, and the vertical partition body 12 is formed by relatively moving the cam groove in the upper and lower portions of the opening of the refrigerating chamber 3. Protrusions 25 and 26 (see FIG. 2) for rotating to the action position are provided.

これにて、左扉６を開放した状態では、縦仕切体１２は退避位置に回動していて邪魔になることはなく、左扉６を閉塞した状態で、縦仕切体１２が作用位置に回動される。この作用位置では、図３に示すように、縦仕切体１２の磁石２２、２３を有する面が、前面を向くようになり、ガスケット８、９の非枢支側を吸着可能となる。この場合、縦仕切体１２の左側の磁石２２（以下、第３の磁石２２という）が、ガスケット８の第１の磁石１０と対向して吸着力が得られる。また、縦仕切体１２の右側の磁石２３（以下、第４の磁石２３という）が、ガスケット９の第２の磁石１１と対向して吸着力が得られる。 Now, when the left door 6 is open, the vertical partition 12 rotates to the retracted position and does not get in the way, and when the left door 6 is closed, the vertical partition 12 is in the working position. It is rotated. At this working position, as shown in FIG. 3, the surface of the vertical partition body 12 having the magnets 22 and 23 faces the front surface, and the non-axial side of the gaskets 8 and 9 can be attracted. In this case, the magnet 22 on the left side of the vertical partition 12 (hereinafter referred to as the third magnet 22) faces the first magnet 10 of the gasket 8 to obtain an attractive force. Further, the magnet 23 on the right side of the vertical partition body 12 (hereinafter referred to as the fourth magnet 23) faces the second magnet 11 of the gasket 9 to obtain an attractive force.

さて、本実施形態では、前記縦仕切体１２の磁石２２、２３またはガスケット８、９の磁石１０、１１は吸着面におけるＮ極とＳ極の割合が異なる磁石とされている。そして、前記縦仕切体１２の磁石２２、２３と前記ガスケット８、９の磁石１０、１１との対向する面（これらを吸着面という）のうち、異極同士が対向する部分の幅方向寸法が、同極同士が対向する部分の幅方向寸法よりも大きく構成されている。特に本実施形態では、縦仕切体１２の各磁石２２、２３及びガスケット８、９の磁石１０、１１は、磁極の数が１極に構成されている。さらに、縦仕切体１２の２つの磁石２２、２３の間隔が、各ガスケット８、９の２つの磁石１０、１１の間隔よりも狭く構成されている。 By the way, in the present embodiment, the magnets 22 and 23 of the vertical partition 12 or the magnets 10 and 11 of the gaskets 8 and 9 are magnets having different ratios of N pole and S pole on the suction surface. Then, among the surfaces facing the magnets 22 and 23 of the vertical partition 12 and the magnets 10 and 11 of the gaskets 8 and 9 (these are referred to as suction surfaces), the width direction dimension of the portion where the different poles face each other is , It is configured to be larger than the width direction dimension of the portion where the same poles face each other. In particular, in the present embodiment, the magnets 22 and 23 of the vertical partition 12 and the magnets 10 and 11 of the gaskets 8 and 9 are configured to have one pole. Further, the distance between the two magnets 22 and 23 of the vertical partition body 12 is narrower than the distance between the two magnets 10 and 11 of the gaskets 8 and 9, respectively.

より具体的には、本実施形態では、上記したガスケット８の第１の磁石１０、ガスケット９の第２の磁石１１、縦仕切体１２の第３の磁石２２及び第４の磁石２３は、図５に横断面で示すような、扉６、７閉塞時の平面的な配置、幅方向寸法及び吸着面における磁極を有する。即ち、第１の磁石１０は、幅方向寸法ａ１が例えば８ｍｍとされ、吸着面の磁極がＳ極の１極とされている。第２の磁石１１は、幅方向寸法ｂ１が例えば８ｍｍとされ、吸着面の磁極がＳ極の１極とされている。 More specifically, in the present embodiment, the first magnet 10 of the gasket 8, the second magnet 11 of the gasket 9, the third magnet 22 of the vertical partition 12, and the fourth magnet 23 are shown in FIG. As shown in the cross section in 5, the doors 6 and 7 have a planar arrangement when closed, widthwise dimensions, and magnetic poles on the suction surface. That is, the width direction dimension a1 of the first magnet 10 is, for example, 8 mm, and the magnetic pole of the suction surface is one pole of the S pole. The width direction dimension b1 of the second magnet 11 is, for example, 8 mm, and the magnetic pole on the suction surface is one pole of the S pole.

これに対し、縦仕切体１２の第３の磁石２２は、幅方向寸法ｃ１が例えば９ｍｍとされ、吸着面の磁極がＮ極の１極とされている。第４の磁石２３も，幅方向寸法ｄ１が例えば９ｍｍとされ、吸着面の磁極がＮ極の１極とされている。この際、第１の磁石１０と、第３の磁石２２とは、外側が揃うように配置され、内側に寸法ｇ１（１ｍｍ）のずれが生じている。第２の磁石１１と、第４の磁石２３とに関しても、外側が揃うように配置され、内側に寸法ｇ１（１ｍｍ）のずれが生じている。従って、縦仕切体１２の２つの磁石２２、２３の間隔が、各ガスケット８、９の２つの磁石１０、１１の間隔よりも、２ｍｍだけ狭くなっている。 On the other hand, the third magnet 22 of the vertical partition body 12 has a width direction dimension c1 of, for example, 9 mm, and the magnetic pole of the suction surface is one pole of the N pole. The fourth magnet 23 also has a width direction dimension d1 of, for example, 9 mm, and the magnetic pole of the suction surface is one pole of the N pole. At this time, the first magnet 10 and the third magnet 22 are arranged so that the outsides are aligned, and a deviation of the dimension g1 (1 mm) occurs inside. The second magnet 11 and the fourth magnet 23 are also arranged so that the outer sides are aligned, and a deviation of the dimension g1 (1 mm) occurs on the inner side. Therefore, the distance between the two magnets 22 and 23 of the vertical partition 12 is narrower by 2 mm than the distance between the two magnets 10 and 11 of the gaskets 8 and 9, respectively.

尚、図５では、ガスケット８、９側の磁石１０、１１をＳ極、縦仕切体１２側の磁石２２、２３をＮ極としたが、Ｎ極とＳ極とが逆であっても良いことは勿論である。また、図５では図示していないが、各磁石１０、１１、２２、２３において、吸着面の反対側の面は、吸着面の磁極と反対の磁極を有しているが、片面つまり吸着面側だけを磁化する構成としても良い。片面だけを磁化した場合、各磁石１０、１１、２２、２３の厚みを薄くすることが可能となる。 In FIG. 5, the magnets 10 and 11 on the gaskets 8 and 9 side are the south poles, and the magnets 22 and 23 on the vertical partition 12 side are the north poles, but the north poles and the south poles may be reversed. Of course. Further, although not shown in FIG. 5, in each of the magnets 10, 11, 22, and 23, the surface opposite to the suction surface has a magnetic pole opposite to the magnetic pole of the suction surface, but one side, that is, the suction surface. It may be configured to magnetize only the side. When only one side is magnetized, the thickness of each magnet 10, 11, 22, and 23 can be reduced.

次に、上記のように構成された本実施形態の冷蔵庫１の作用・効果について述べる。即ち、本実施形態の冷蔵庫１においては、冷蔵室３を開閉する観音開き式の扉６、７を有し、扉６、７のガスケット８、９と縦仕切体１２との双方に磁石１０、１１、２２、２３を設けることによって、優れた吸着力を得て、高い密閉性を得ることができる。ここで、各扉６、７の冷蔵庫本体２に対する取付け位置のばらつき、各扉６、７におけるガスケット８、９の取付け位置のばらつき、縦仕切体１２における回転軸Ｏ（支持部１９）の位置のばらつき等により、ガスケット８、９と縦仕切体１２との間の磁石１０、１１、２２、２３の位置に幅方向のずれが生ずる虞が考えられる。 Next, the action / effect of the refrigerator 1 of the present embodiment configured as described above will be described. That is, the refrigerator 1 of the present embodiment has double doors 6 and 7 for opening and closing the refrigerating chamber 3, and magnets 10 and 11 are provided on both the gaskets 8 and 9 of the doors 6 and 7 and the vertical partition 12. , 22, 23 can be provided to obtain excellent adsorption force and high airtightness. Here, variations in the mounting positions of the doors 6 and 7 with respect to the refrigerator body 2, variations in the mounting positions of the gaskets 8 and 9 in the doors 6 and 7, and positions of the rotating shaft O (support portion 19) in the vertical partition 12 Due to variations and the like, there is a possibility that the positions of the magnets 10, 11, 22, and 23 between the gaskets 8 and 9 and the vertical partition 12 may be displaced in the width direction.

ところが、本実施形態では、各ガスケット８、９の磁石１０、１１と、縦仕切体１２の各磁石２２、２３との間においては、図５に示すような正規の位置にあっては、それらのうちの一方の吸着面、この場合磁石２２、２３の幅方向寸法（面積）の広いＮ極と、他方の吸着面、この場合磁石１０、１１幅方向寸法（面積）の広いＳ極とが対向する。これにて、ガスケット８、９の吸着面（磁石１０、１１）が、縦仕切体１２の吸着面（磁石２２、２３）に対して、高い吸着力で吸着される。 However, in the present embodiment, between the magnets 10 and 11 of the gaskets 8 and 9 and the magnets 22 and 23 of the vertical partition 12, they are in the regular positions as shown in FIG. One of the suction surfaces, in this case, the north pole having a wide width direction dimension (area) of the magnets 22 and 23, and the other suction surface, in this case, the S pole having a wide width direction dimension (area) of the magnets 10 and 11. opposite. As a result, the suction surfaces (magnets 10 and 11) of the gaskets 8 and 9 are attracted to the suction surfaces (magnets 22 and 23) of the vertical partition 12 with a high suction force.

仮に、ガスケット８、９と縦仕切体１２との間で左右方向の位置ずれがあって、磁石１０、１１と、磁石２２、２３とが左右方向がずれたとしても、同極同士が対向する部分の面積は小さく（この場合ゼロ）、異極同士が対向する部分の面積を相対的に大きく確保することができる。従って、ガスケット８、９と縦仕切体１２との間の多少の位置ずれが生じた場合でも、ガスケット８、９と縦仕切体１２との間での十分な吸着力を確保することができ、ひいては、吸着力の低下に起因する不具合の発生を未然に防止することができるという効果を奏する。 Even if the gaskets 8 and 9 and the vertical partition 12 are displaced in the left-right direction and the magnets 10 and 11 and the magnets 22 and 23 are displaced in the left-right direction, the same poles face each other. The area of the portion is small (zero in this case), and the area of the portion where the different poles face each other can be secured relatively large. Therefore, even if a slight misalignment occurs between the gaskets 8 and 9 and the vertical partition body 12, a sufficient suction force between the gaskets 8 and 9 and the vertical partition body 12 can be ensured. As a result, it is possible to prevent the occurrence of defects due to a decrease in the adsorption force.

特に本実施形態では、各磁石１０、１１、２２、２３の磁極の数が１極に構成されているので、簡単な構成で済ませながらも、同極同士が対向して反発するといった事態が発生することなく、高い効果を得ることができる。また、本実施形態では、縦仕切体１２の２つの磁石２２、２３の間隔が、各ガスケット８、９の２つの磁石１０、１１の間隔よりも狭く構成されているので、ガスケット８、９と縦仕切体１２との間で、いずれの方向にずれが生じても、適度な吸着力を得ることが可能となる。 In particular, in the present embodiment, since the number of magnetic poles of each magnet 10, 11, 22, and 23 is configured to be one pole, a situation occurs in which the same poles face each other and repel each other even though the configuration is simple. A high effect can be obtained without doing so. Further, in the present embodiment, the distance between the two magnets 22 and 23 of the vertical partition 12 is narrower than the distance between the two magnets 10 and 11 of the gaskets 8 and 9, so that the gaskets 8 and 9 are used. It is possible to obtain an appropriate suction force regardless of the direction of deviation from the vertical partition body 12.

（２）第２〜第５の実施形態、その他の実施形態
図６は、第２の実施形態を示すものであり、扉６、７閉塞時の、第１〜第４の磁石の平面的な配置、幅方向寸法及び吸着面における磁極を表すものである。この第２の実施形態では、ガスケット８に第１の磁石３１が設けられ、ガスケット９に第２の磁石３２が設けられている。縦仕切体１２は、第１の実施形態と同様に、第３の磁石２２及び第４の磁石２３を収容している。 (2) Second to Fifth Embodiments and Other Embodiments FIG. 6 shows a second embodiment, in which the first to fourth magnets are planar when the doors 6 and 7 are closed. It represents the arrangement, the widthwise dimension, and the magnetic poles on the suction surface. In this second embodiment, the gasket 8 is provided with the first magnet 31, and the gasket 9 is provided with the second magnet 32. The vertical partition body 12 accommodates the third magnet 22 and the fourth magnet 23, as in the first embodiment.

このとき、前記第１の磁石３１の吸着面の磁極は、幅方向（左右方向）に、左から順にＮ極、Ｓ極、Ｎ極の３極が並ぶように構成されている。このとき、例えば、左のＮ極の幅方向寸法ａ１１は、１．５ｍｍ、Ｓ極の幅方向寸法ａ１２は、５ｍｍ、右のＮ極の幅方向寸法ａ１３は、１．５ｍｍとされている。全体の幅方向寸法ａ１は、８ｍｍである。第１の磁石３１と、第３の磁石２２とは、外側が揃うように配置され、内側に寸法ｇ１（１ｍｍ）のずれが生じている。これにて、第１の磁石３１と第３の磁石２２との対向する部分にあっては、異極となる部分の幅方向寸法（面積）が比較的大きく、同極となる部分の幅方向寸法（面積）が比較的小さく（ゼロ）なる。 At this time, the magnetic poles on the suction surface of the first magnet 31 are configured such that three poles, N pole, S pole, and N pole, are arranged in order from the left in the width direction (left-right direction). At this time, for example, the width direction dimension a11 of the left N pole is 1.5 mm, the width direction dimension a12 of the S pole is 5 mm, and the width direction dimension a13 of the right N pole is 1.5 mm. The overall width direction dimension a1 is 8 mm. The first magnet 31 and the third magnet 22 are arranged so that the outer sides are aligned with each other, and a deviation of the dimension g1 (1 mm) occurs on the inner side. As a result, in the portion where the first magnet 31 and the third magnet 22 face each other, the width direction dimension (area) of the portion having different poles is relatively large, and the width direction of the portion having the same poles. The size (area) becomes relatively small (zero).

また、前記第２の磁石３２についても、磁極が、左から順にＮ極、Ｓ極、Ｎ極の３極が並ぶように設けられている。例えば、左のＮ極の幅方向寸法ｂ１１は、１．５ｍｍ、Ｓ極の幅方向寸法ｂ１２は、５ｍｍ、右のＮ極の幅方向寸法ｂ１３は、１．５ｍｍとされている。全体の幅方向寸法ｂ１は、８ｍｍである。第２の磁石３２と、第３の磁石２２とは、外側が揃うように配置され、内側に寸法ｇ１（１ｍｍ）のずれが生じている。これにて、第２の磁石３２と第４の磁石２３との対向する部分にあっては、異極となる部分の幅方向寸法（面積）が比較的大きく、同極となる部分の幅方向寸法（面積）が比較的小さく（ゼロ）なる。 Further, the second magnet 32 is also provided so that the magnetic poles are arranged so that the three poles of N pole, S pole, and N pole are arranged in order from the left. For example, the width direction b11 of the left N pole is 1.5 mm, the width direction b12 of the S pole is 5 mm, and the width direction b13 of the right N pole is 1.5 mm. The overall width direction dimension b1 is 8 mm. The second magnet 32 and the third magnet 22 are arranged so that the outer sides are aligned with each other, and a deviation of the dimension g1 (1 mm) occurs on the inner side. As a result, in the portion where the second magnet 32 and the fourth magnet 23 face each other, the width direction dimension (area) of the portion having different poles is relatively large, and the width direction of the portion having the same poles. The size (area) becomes relatively small (zero).

上記構成において、磁石３１、３２、２２、２３が正規の位置にある状態では、第３の磁石２２及び第４の磁石２３の幅方向寸法（面積）の広いＮ極と、第１の磁石３１及び第２の磁石３２の幅方向寸法（面積）の広いＳ極とが夫々対向する。また、同極つまり第１の磁石３１及び第２の磁石３２のＮ極と、第３の磁石２２及び第４の磁石２３のＮ極とが対向する面積（幅方向寸法）は、異極が対向する面積に比べて十分に小さいものとなる。これにより、ガスケット８、９が、縦仕切体１２の吸着面に対して、高い吸着力で吸着される。 In the above configuration, when the magnets 31, 32, 22, and 23 are in the normal positions, the N pole having a wide width direction dimension (area) of the third magnet 22 and the fourth magnet 23 and the first magnet 31 And the S pole having a wide width direction dimension (area) of the second magnet 32 faces each other. Further, the same pole, that is, the area (width direction dimension) where the north poles of the first magnet 31 and the second magnet 32 and the north poles of the third magnet 22 and the fourth magnet 23 face each other has different poles. It is sufficiently small compared to the facing area. As a result, the gaskets 8 and 9 are attracted to the suction surface of the vertical partition body 12 with a high suction force.

そして、仮に磁石３１、３２、２２、２３の位置ずれが発生したとしても、第３の磁石２２及び第４の磁石２３のＮ極と、第１の磁石３１及び第２の磁石３２のＳ極との対向する面積にほとんど変動はなく、同極同士の対向する面積は比較的小さく済むものとなる。従って、この第２の実施形態においても、ガスケット８、９と縦仕切体１２との間の多少の位置ずれが生じた場合でも、それらの間での吸着力を確保することができる。ひいては、吸着力の低下に起因する不具合の発生を未然に防止することができる。 Then, even if the magnets 31, 32, 22, and 23 are misaligned, the north poles of the third magnet 22 and the fourth magnet 23 and the south poles of the first magnet 31 and the second magnet 32 are generated. There is almost no change in the area facing the magnet, and the area facing the same poles is relatively small. Therefore, also in this second embodiment, even if there is a slight misalignment between the gaskets 8 and 9 and the vertical partition body 12, the suction force between them can be ensured. As a result, it is possible to prevent the occurrence of defects due to a decrease in the suction force.

特に本実施形態では、第１の磁石３１及び第２の磁石３２を横方向に３極が並ぶように構成したので、比較的簡易な構成で、Ｎ極、Ｓ極の面積の相違を得ることができる。また、本実施形態では、第１の磁石３１及び第２の磁石３２の３極が横方向に並ぶ磁極にあって、幅寸法が他と異なるものが含まれている構成としたので、目的とする適度な吸着力を得ることが容易となる。さらに、縦仕切体１２の２つの磁石２２、２３の間隔が、各ガスケット８、９の２つの磁石３１、３２の間隔よりも狭く構成されているので、ガスケット８、９と縦仕切体１２との間で、いずれの方向にずれが生じても、適度な吸着力を得ることが可能となる。 In particular, in the present embodiment, since the first magnet 31 and the second magnet 32 are configured so that three poles are arranged in the lateral direction, a difference in the areas of the north and south poles can be obtained with a relatively simple configuration. Can be done. Further, in the present embodiment, the three poles of the first magnet 31 and the second magnet 32 are on the magnetic poles arranged in the horizontal direction, and the width dimension is different from the others. It becomes easy to obtain an appropriate adsorption force. Further, since the distance between the two magnets 22 and 23 of the vertical partition 12 is narrower than the distance between the two magnets 31 and 32 of the gaskets 8 and 9, the gaskets 8 and 9 and the vertical partition 12 It is possible to obtain an appropriate adsorption force regardless of the direction of deviation between the two.

図７は、第３の実施形態を示している。この第３の実施形態では、第１の磁石３１及び第２の磁石３２は、上記第２の実施形態と同等の構成を備えている。そして、縦仕切体１２側に設けられる第３の磁石４１及び第４の磁石４２の構成が、上記第２の実施形態と異なっている。即ち、例えば、第３の磁石４１は、幅方向寸法ｃ２が８ｍｍとされ、吸着面の磁極がＮ極の１極とされている。第４の磁石４２も、幅方向寸法ｄ２が８ｍｍとされ、吸着面の磁極がＮ極の１極とされている。これら第３の磁石４１及び第４の磁石４２の幅方向寸法は、第１の磁石３１及び第２の磁石３２の幅方向寸法と同等とされている。 FIG. 7 shows a third embodiment. In this third embodiment, the first magnet 31 and the second magnet 32 have the same configuration as that of the second embodiment. The configuration of the third magnet 41 and the fourth magnet 42 provided on the vertical partition body 12 side is different from that of the second embodiment. That is, for example, the third magnet 41 has a width direction dimension c2 of 8 mm, and the magnetic pole of the suction surface is one pole of the N pole. The fourth magnet 42 also has a width direction dimension d2 of 8 mm, and the magnetic pole of the suction surface is one pole of the N pole. The widthwise dimensions of the third magnet 41 and the fourth magnet 42 are the same as the widthwise dimensions of the first magnet 31 and the second magnet 32.

このとき、第２の磁石３２と第４の磁石４２とは、両端が揃うように配置されている。これに対し、第３の磁石４１は、第１の磁石３１に対し、図で左側に寸法ｇ２（例えば１ｍｍ）だけずれて配置されている。従って、縦仕切体１２の２つの磁石４１、４２の間隔が、各ガスケット８、９の２つの磁石３１、３２の間隔よりも、１ｍｍだけ狭くなっている。 At this time, the second magnet 32 and the fourth magnet 42 are arranged so that both ends are aligned. On the other hand, the third magnet 41 is arranged on the left side in the drawing with a deviation of the dimension g2 (for example, 1 mm) from the first magnet 31. Therefore, the distance between the two magnets 41 and 42 of the vertical partition body 12 is 1 mm narrower than the distance between the two magnets 31 and 32 of the gaskets 8 and 9, respectively.

この第３の実施形態においても、上記第２の実施形態と同様に、第３の磁石４１及び第４の磁石４２のＮ極と、第１の磁石３１及び第２の磁石３２のＳ極との夫々対向する面積を大きく確保することができ、同極同士の対向する面積は比較的小さく済む。また、ガスケット８、９と縦仕切体１２との間の多少の位置ずれが生じた場合でも、吸着力にほとんど変動はない。従って、ガスケット８、９と縦仕切体１２との間での高い吸着力を確保することができ、吸着力の低下に起因する不具合の発生を未然に防止することができる。 Also in this third embodiment, similarly to the second embodiment, the north pole of the third magnet 41 and the fourth magnet 42 and the south pole of the first magnet 31 and the second magnet 32 It is possible to secure a large area facing each other, and the area facing the same poles can be relatively small. Further, even if a slight positional deviation occurs between the gaskets 8 and 9 and the vertical partition body 12, there is almost no change in the suction force. Therefore, it is possible to secure a high suction force between the gaskets 8 and 9 and the vertical partition body 12, and it is possible to prevent the occurrence of a defect due to a decrease in the suction force.

図８は、第４の実施形態を示している。この第４の実施形態では、上記第２、第３の実施形態と同様に、各ガスケット８、９内の第１の磁石３１及び第２の磁石３２の磁極が３極に構成されている。これと共に、縦仕切体１２側に設けられる第３の磁石５１及び第４の磁石５２の磁極が２極に構成され、それら第３の磁石５１及び第４の磁石５２は、磁極の並び方が同じに構成されている。しかもこのとき、縦仕切体１２内の磁石５１、５２における回転軸Ｏ（支持部１９）に近い側の磁極、つまり最も左側の磁極（この場合Ｓ極）が、各ガスケット内８、９の第１及び第２の磁石３１及び３２の中央の磁極（Ｓ極）と同じとなるように構成されている。 FIG. 8 shows a fourth embodiment. In the fourth embodiment, as in the second and third embodiments, the magnetic poles of the first magnet 31 and the second magnet 32 in the gaskets 8 and 9 are configured to have three poles. At the same time, the magnetic poles of the third magnet 51 and the fourth magnet 52 provided on the vertical partition body 12 side are configured to have two poles, and the third magnet 51 and the fourth magnet 52 have the same arrangement of magnetic poles. It is configured in. Moreover, at this time, the magnetic poles on the magnets 51 and 52 in the vertical partition 12 on the side closer to the rotation axis O (support portion 19), that is, the leftmost magnetic pole (in this case, the S pole) are the 8th and 9th magnetic poles in the gaskets. It is configured to be the same as the central magnetic pole (S pole) of the first and second magnets 31 and 32.

具体的には、第３の磁石５１は、吸着面の磁極は、左側にＳ極、右側にＮ極の２極が並ぶように構成されている。このとき、第３の磁石５１は、例えば、全体の幅方向寸法ｃ２が８ｍｍとされ、そのうち左のＳ極の幅方向寸法ｃ２１は４ｍｍ、右のＮ極の幅方向寸法ｃ２２も４ｍｍとされている。第４の磁石５２も、左側にＳ極、右側にＮ極の２極が並び、全体の幅方向寸法ｄ２が８ｍｍとされ、そのうち左のＳ極の幅方向寸法ｄ２１が４ｍｍ、右のＮ極の幅方向寸法ｄ２２も４ｍｍとされている。 Specifically, the third magnet 51 is configured such that the magnetic poles on the suction surface are arranged with two poles, an S pole on the left side and an N pole on the right side. At this time, for the third magnet 51, for example, the overall width direction dimension c2 is 8 mm, of which the width direction dimension c21 of the left S pole is 4 mm and the width direction dimension c22 of the right N pole is also 4 mm. There is. The fourth magnet 52 also has two poles, an S pole on the left side and an N pole on the right side, and the overall width direction dimension d2 is 8 mm, of which the width direction dimension d21 of the left S pole is 4 mm and the right N pole. The width direction dimension d22 of is also set to 4 mm.

このとき、第２の磁石３２と第４の磁石５２とは、両端が揃うように配置されている。これに対し、第３の磁石５１は、第１の磁石３１に対し、図で左側に寸法ｇ２（例えば１ｍｍ）だけずれて配置されている。従って、縦仕切体１２の２つの磁石５１、５２の間隔が、各ガスケット８、９の２つの磁石３１、３２の間隔よりも、１ｍｍだけ狭くなっている。この場合も、やはり、第１及び第２の磁石３１及び３２と、第３及び第４の磁石５１及び５２との対向する面のうち、異極同士が対向する部分の幅方向寸法が、同極同士が対向する部分の幅方向寸法よりも大きく構成されている。 At this time, the second magnet 32 and the fourth magnet 52 are arranged so that both ends are aligned. On the other hand, the third magnet 51 is arranged on the left side in the drawing with a deviation of the dimension g2 (for example, 1 mm) from the first magnet 31. Therefore, the distance between the two magnets 51 and 52 of the vertical partition 12 is 1 mm narrower than the distance between the two magnets 31 and 32 of the gaskets 8 and 9, respectively. In this case as well, the widthwise dimensions of the portions of the surfaces facing the first and second magnets 31 and 32 and the third and fourth magnets 51 and 52 where the different poles face each other are the same. It is configured to be larger than the width direction dimension of the portion where the poles face each other.

この第４の実施形態においても、第１の磁石３１及び第２の磁石３２と、第３の磁石５１及び第４の磁石５２との間で、異極同士が対向する部分の幅方向寸法（面積）を比較的大きく確保することができる。また、部分的に同極同士の対向状態をつくることにより、ガスケット８，９及び縦仕切体１２に関して、取付け位置等の厳密な管理（設計通りの配置）を不要とし、多少の位置ずれを許容しながら、必要かつ十分な吸着力を得ることができる。従って、観音開き式の扉６、７のガスケット８、９と縦仕切体１２との双方に磁石を設けたものにあって、ガスケット８、９と縦仕切体１２との間での高い吸着力を確保することができ、吸着力の低下に起因する不具合の発生を未然に防止することができる。 Also in this fourth embodiment, the width direction dimension of the portion where the different poles face each other between the first magnet 31 and the second magnet 32 and the third magnet 51 and the fourth magnet 52 ( Area) can be secured relatively large. In addition, by partially creating a state in which the same poles face each other, it is not necessary to strictly control the mounting positions of the gaskets 8 and 9 and the vertical partition 12 (arrangement as designed), and some misalignment is allowed. However, a necessary and sufficient adsorption force can be obtained. Therefore, magnets are provided on both the gaskets 8 and 9 of the double doors 6 and 7 and the vertical partition 12, and a high attractive force between the gaskets 8 and 9 and the vertical partition 12 can be obtained. It can be secured, and it is possible to prevent the occurrence of a problem due to a decrease in the suction force.

特に本実施形態では、第３の磁石５１の回転軸Ｏ側の磁極が、ガスケット８の第１の磁石３１の中央の磁極と同じ（Ｓ極）となるように構成した。これにより、左扉６の開放状態からの閉塞時に、縦仕切体１２の回転軸Ｏ側の第３の磁石５１が、ガスケット８の第１の磁石３１を吸着する際に、同極が対向することによって左扉６の閉扉の直前まで反発力が与えられるようになる。これにて、縦仕切体１２の移動（回転）が促進されるようになり、縦仕切体１２の変位不良（回転不足）を防止することができるといったメリットも得ることができる。 In particular, in the present embodiment, the magnetic pole on the rotation shaft O side of the third magnet 51 is configured to be the same (S pole) as the central magnetic pole of the first magnet 31 of the gasket 8. As a result, when the left door 6 is closed from the open state, the same poles face each other when the third magnet 51 on the rotation axis O side of the vertical partition 12 attracts the first magnet 31 of the gasket 8. As a result, the repulsive force is given until just before the closing of the left door 6. As a result, the movement (rotation) of the vertical partition body 12 is promoted, and it is possible to obtain an advantage that the displacement defect (insufficient rotation) of the vertical partition body 12 can be prevented.

図９は、第５の実施形態を示しており、上記第４の実施形態と異なる点は、第３の磁石６１の構成にある。即ち、第３の磁石６１は、吸着面の磁極が、左側にＮ極、右側にＳ極の２極が並ぶように構成されている。このとき、第３の磁石６１は、例えば、全体の幅方向寸法ｃ３が８ｍｍとされ、そのうち左のＮ極の幅方向寸法ｃ３１は４ｍｍ、右のＳ極の幅方向寸法ｃ３２も４ｍｍとされている。また、第３の磁石６１は、第１の磁石３１に対し、図で左側に寸法ｇ２（例えば１ｍｍ）だけずれて配置されている。 FIG. 9 shows a fifth embodiment, which differs from the fourth embodiment in the configuration of the third magnet 61. That is, the third magnet 61 is configured such that the magnetic poles on the suction surface are arranged with two poles, an N pole on the left side and an S pole on the right side. At this time, for the third magnet 61, for example, the overall width direction dimension c3 is 8 mm, of which the width direction dimension c31 of the left N pole is 4 mm and the width direction dimension c32 of the right S pole is also 4 mm. There is. Further, the third magnet 61 is arranged so as to be offset from the first magnet 31 by a dimension g2 (for example, 1 mm) on the left side in the drawing.

この第５の実施形態においても、第１の磁石３１及び第２の磁石３２と、第３の磁石６１及び第４の磁石５２との間で、異極同士が対向する部分の幅方向寸法（面積）を比較的大きく確保することができる。従って、観音開き式の扉６、７のガスケット８、９と縦仕切体１２との双方に磁石を設けたものにあって、ガスケット８、９と縦仕切体１２との間での高い吸着力を確保することができ、吸着力の低下に起因する不具合の発生を未然に防止することができる。 Also in this fifth embodiment, the width direction dimension of the portion where the different poles face each other between the first magnet 31 and the second magnet 32 and the third magnet 61 and the fourth magnet 52 ( Area) can be secured relatively large. Therefore, in the case where magnets are provided on both the gaskets 8 and 9 of the double doors 6 and 7 and the vertical partition 12, a high attractive force between the gaskets 8 and 9 and the vertical partition 12 can be obtained. It can be secured, and it is possible to prevent the occurrence of a problem due to a decrease in the suction force.

尚、上記した各実施形態では、各磁石の磁極の数を、１極或いは２極或いは３極に構成したが、縦仕切体の各磁石又は各ガスケットの磁石の、少なくとも一方については、磁極の数を横方向に４極以上が並ぶように構成しても良い。この場合、磁極の数を多くすることにより、位置ずれが発生した場合でも、多少のばらつきを吸収することができ、十分な吸着力を得ることができる。各部の磁石を夫々１個の磁石から構成するものに限らず、複数個の磁石から構成しても良い。 In each of the above-described embodiments, the number of magnetic poles of each magnet is set to 1 pole, 2 poles, or 3 poles, but at least one of the magnets of the vertical partition and the magnets of each gasket has magnetic poles. The number may be configured so that four or more poles are lined up in the horizontal direction. In this case, by increasing the number of magnetic poles, even if the position shift occurs, some variation can be absorbed, and a sufficient suction force can be obtained. The magnets of each part are not limited to one magnet each, and may be composed of a plurality of magnets.

また、上記各実施形態における、ガスケット側と縦仕切体側との磁石の磁極を逆にしたり、磁極の数を逆にしたりしても良いことは勿論である。縦仕切体を右扉側に設ける構成としても良い。磁石の各部の幅方向寸法や、ずれ量等の具体的数値に関しても、一例を挙げたに過ぎず、適宜変更することが可能である。その他、例えば冷蔵庫の全体構成としても、各貯蔵室の配置や数を変更して実施することが可能であるなど、要旨を逸脱しない範囲内で適宜変更して実施し得るものである。 Further, it goes without saying that the magnetic poles of the magnets on the gasket side and the vertical partition side in each of the above embodiments may be reversed, or the number of magnetic poles may be reversed. A vertical partition may be provided on the right door side. Specific numerical values such as the width direction dimension of each part of the magnet and the amount of deviation are only given as an example, and can be changed as appropriate. In addition, for example, the overall configuration of the refrigerator can be changed as appropriate within a range that does not deviate from the gist, such as the arrangement and number of storage rooms can be changed.
