Description

本発明は左右に二つの扉を有し両開きが出来るすなわち観音開き式の扉を有する冷蔵庫に関するものである。   The present invention relates to a refrigerator that has two doors on the left and right and can be double-opened, that is, a double door.

大型の冷蔵庫、特に幅広の冷蔵庫においては、実使用に必要な面積を小さくすることを目的に、冷蔵庫扉を冷蔵庫本体の略半分で左右に分割し観音開き式扉を採用している。また、この観音開き式扉には、左右どちらの扉からでも優先順位をつけず開閉する構成のものが知られている(例えば、特許文献１参照)。その構成の概略を示すと図５、図６、図７の通りである。   In large refrigerators, particularly wide refrigerators, a double door is used by dividing the refrigerator door into left and right parts of the refrigerator body for the purpose of reducing the area required for actual use. In addition, a door opening type door is known that can be opened and closed without prioritization from either the left or right door (see, for example, Patent Document 1). The outline of the configuration is shown in FIGS. 5, 6, and 7. FIG.

第一扉４１を開いた状態において回転遮閉体３１は収納部材３２内に収納しておく。次に第一扉４１を閉じていくと、回転遮閉体３１の係合部３１Ａが案内溝３３の第一扉４１側の入り口から案内溝３３内に進入し、次に突提３４の曲面３４Ａに隅部が当接し、それに案内されて回動される。   In the state where the first door 41 is opened, the rotary shield 31 is stored in the storage member 32. Next, when the first door 41 is closed, the engaging portion 31A of the rotary shield 31 enters the guide groove 33 from the entrance of the guide groove 33 on the first door 41 side, and then the curved surface of the projecting 34 A corner portion comes into contact with 34A and is guided and rotated.

これによって回転遮閉体３１は反時計回りに回動される。そして回転遮閉体３１前面は開口３５と略面一となり、第一扉４１、第二扉４２のガスケット３６の着磁面を構成し、これによって開口３５は密閉される。   As a result, the rotary shield 31 is rotated counterclockwise. The front surface of the rotary shield 31 is substantially flush with the opening 35 and constitutes a magnetized surface of the gasket 36 of the first door 41 and the second door 42, thereby sealing the opening 35.

また、第一扉４１を開けば、回転遮閉体３１は突部３７の曲面３７Ａに沿って時計回りに回動し、収納部材３２内に収納される。   Further, when the first door 41 is opened, the rotary blocking body 31 rotates clockwise along the curved surface 37 </ b> A of the protrusion 37 and is stored in the storage member 32.

実開昭６２−６３６９２号公報（第２頁、第１、第２、第５図）Japanese Utility Model Publication No. 62-63692 (page 2, first, second, and fifth figures)

しかしながら、前記する従来の構成では、片手で一度の操作で開閉できる扉は左右いずれか一方の扉で、他方の扉は別途開閉する必要がある。第一扉を開動作しても、第二扉は閉状態のままであり、第二扉が邪魔で開口部の略半幅より大きい貯蔵物を出し入れすることは出来ない。すなわち、冷蔵庫幅の略半分以上の幅を有する物を出し入れする際には、貯蔵物を一旦別の場所に放置し両方の扉を開状態にし、放置した貯蔵物を出し入れする必要があった。すなわち、従来の観音開き扉式冷蔵庫では観音扉よりも幅の広い貯蔵物を出し入れする際に一度の開閉操作では出し入れできないという問題があった。   However, in the conventional configuration described above, the door that can be opened and closed by one operation with one hand is either the left or right door, and the other door needs to be opened and closed separately. Even if the first door is opened, the second door remains in a closed state, and the second door is obstructed, so that stored items larger than approximately half the width of the opening cannot be taken in and out. That is, when putting in or taking out a product having a width of approximately half or more of the width of the refrigerator, it is necessary to leave the stored product in another place, open both doors, and put in and out the stored product. In other words, the conventional double door type refrigerator has a problem that it cannot be put in and out by a single opening / closing operation when putting in / out a stored item wider than the double door.

本発明はかかる従来の問題点を解決することを課題とするものである。   An object of the present invention is to solve such conventional problems.

前記する目的を達成する為に、請求項１記載に係る発明は、外側がヒンジにより冷蔵庫に軸支持されている一対の扉をなす第一扉と第二扉を有し、第一扉及び第二扉には、扉を支持する軸を中心とする歯車を有し、前記歯車と噛み合い回転する歯車を有し、前記歯車は他方の扉の歯車と噛み合う。上記の構成によれば、歯車は扉の開閉に追従し回転動作する。すなわち、第一扉を使用者が開閉動作を行なう時、それに追従し第二扉が開閉動作をする。また、第二扉を使用者が開閉動作を行なう時、それに追従し第一扉が開閉動作をする。   In order to achieve the above object, the invention according to claim 1 has a first door and a second door that form a pair of doors whose outer sides are axially supported by the refrigerator by hinges. The two doors have a gear centered on an axis that supports the door, a gear that meshes with the gear and rotates, and the gear meshes with a gear of the other door. According to the above configuration, the gear rotates following the opening and closing of the door. That is, when the user opens / closes the first door, the second door opens / closes following the opening / closing operation. When the user opens / closes the second door, the first door opens / closes following the opening / closing operation.

本発明によれば第一扉または第二扉の開閉操作時に、その動作に追従して他方の扉（第二扉または第一扉）も開閉動作を行ない、幅の広い貯蔵物を出し入れする再に、他方の扉が邪魔となり貯蔵物を一旦別の場所に放置する必要は無く、冷蔵庫本体の開口全幅の貯蔵物出し入れを一度の動作で行なうことができ、取扱いが便利な冷蔵庫を提供することができる。   According to the present invention, at the time of opening / closing operation of the first door or the second door, the other door (second door or first door) is also opened / closed following the operation, and the wide storage is taken in / out. In addition, it is not necessary to leave the storage in another place because the other door is obstructing, and it is possible to carry out storage in and out of the full width of the refrigerator body in one operation, and provide a refrigerator that is convenient to handle. Can do.

以下本発明の実施例を添付の図面を参照しつつ説明する。図１は本発明の一実施例における扉閉時の平面断面図である。図２及び図３は本発明の一実施例における扉開途中の平面断面図。図４は本発明の一実施例における扉開時の平面断面図である。この一対の扉をなす第一扉１０と第二扉２０は、それぞれ外側がヒンジ１１及び２１により冷蔵庫本体１に軸支持されている。前記、第一扉１０の開放端側には、第二扉２０側へ進退する様に回動する回転遮閉体３が取り付けてある。この回転遮閉体３は第一扉１０の開閉に合わせ冷蔵庫本体１の近傍で回転遮閉体軸２を中心に回転動作し、冷蔵庫の開口部における第一扉１０及び第二扉２０の隙間を塞ぐ働きをする。   Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan sectional view when a door is closed in one embodiment of the present invention. 2 and 3 are plan sectional views in the middle of opening the door in one embodiment of the present invention. FIG. 4 is a plan sectional view when the door is opened in one embodiment of the present invention. The outer sides of the first door 10 and the second door 20 forming the pair of doors are axially supported by the refrigerator main body 1 by hinges 11 and 21, respectively. On the open end side of the first door 10, a rotary blocking body 3 that rotates so as to advance and retreat toward the second door 20 is attached. The rotary shield 3 rotates around the rotary shield shaft 2 in the vicinity of the refrigerator body 1 in accordance with the opening and closing of the first door 10, and the gap between the first door 10 and the second door 20 at the opening of the refrigerator. Works to block.

第一扉１０は、開閉に合わせヒンジ１１を中心として回動する内歯車１２を有し、冷蔵庫本体１は内歯車ガイド１３を有し、確実に内歯車１２をヒンジ１１を中心に回動させている。また、内歯車１２は歯車１４を従動させ、歯車１４と歯車１５、歯車１５と歯車１６、歯車１６と歯車１７はそれぞれ噛み合っている。   The first door 10 has an internal gear 12 that rotates about the hinge 11 in accordance with opening and closing, the refrigerator body 1 has an internal gear guide 13, and reliably rotates the internal gear 12 about the hinge 11. ing. The internal gear 12 drives the gear 14, and the gear 14 and the gear 15, the gear 15 and the gear 16, and the gear 16 and the gear 17 are engaged with each other.

第二扉２０は、開閉に合わせヒンジ２１を中心として回動する内歯車２２を有し、冷蔵庫本体１は内歯車ガイド２３を有し、確実に内歯車２２をヒンジ２１を中心に回動させている。また、内歯車２２は歯車２４を従動させ、歯車２４と歯車２５、歯車２５と歯車２６、歯車２６と歯車２７はそれぞれ噛み合っている。また歯車２７は前記歯車１７とも噛み合っている。   The second door 20 has an internal gear 22 that rotates about the hinge 21 in accordance with opening and closing, and the refrigerator main body 1 has an internal gear guide 23, and reliably rotates the internal gear 22 about the hinge 21. ing. The internal gear 22 drives the gear 24, and the gear 24 and the gear 25, the gear 25 and the gear 26, and the gear 26 and the gear 27 are engaged with each other. The gear 27 is also meshed with the gear 17.

前記内歯車１２及び２２は、それぞれ厚さ方向に１２ａ、１２ｂ、１２ｃ（２２ａ、２２ｂ、２２ｃ）と重なって構成されている。最上段の内歯車１２ａ（２２ａ）及び２段目の内歯車１２ｂ（２２ｂ）はガイド溝１８ａ及びガイド溝１８ｂ（２８ａ及び２８ｂ）を有し、２段目の内歯車１２ｂ（２２ｂ）及び最下段の内歯車１２ｃ（２２ｃ）はガイドピン１９ｂ及び１９ｃ（２９ｂ及び２９ｃ）が設けられている。前記ガイド溝１８ａ、１８ｂ（２８ａ、２８ｂ）の量終端部はバネ製を有した構造を有しており、ガイドピン１９ｂ、１９ｃ（２９ｂ、２９ｃ）を着脱可能に保持することができ、量終端部以外の部分では前記ガイドピン１９ｂ、１９ｃ（２９ｂ、２９ｃ）は自由に周動することができる。   The internal gears 12 and 22 are configured to overlap with 12a, 12b, and 12c (22a, 22b, and 22c) in the thickness direction, respectively. The uppermost internal gear 12a (22a) and the second internal gear 12b (22b) have a guide groove 18a and a guide groove 18b (28a and 28b), and the second internal gear 12b (22b) and the lowermost step. The internal gear 12c (22c) is provided with guide pins 19b and 19c (29b and 29c). The end portions of the guide grooves 18a and 18b (28a and 28b) have a structure made of a spring, and can detachably hold the guide pins 19b and 19c (29b and 29c). In portions other than the portion, the guide pins 19b and 19c (29b and 29c) can freely move.

以上の構成によれば、第一扉１０を開動作すると、内歯車１２ａはヒンジ１１を中心に時計回り方向に回動し、内歯車１２ａのガイド溝１８ａに内歯車１２ｂのガイドピン１９ｂが接し、歯車１４を従動させる。歯車１４の回転は歯車１５及び１６を介し歯車１７を回動する。歯車１７の回動は歯車２７を回動させ、歯車２６及び歯車２５を介し歯車２４を回動する、歯車２４の回転は内歯車２２ａ、２２ｂ及び２２ｃをヒンジ２１を中心に回動させ、第二扉２０を開動作する。   According to the above configuration, when the first door 10 is opened, the internal gear 12a rotates clockwise around the hinge 11, and the guide pin 19b of the internal gear 12b contacts the guide groove 18a of the internal gear 12a. The gear 14 is driven. The rotation of the gear 14 rotates the gear 17 via the gears 15 and 16. The rotation of the gear 17 rotates the gear 27 and rotates the gear 24 via the gear 26 and the gear 25. The rotation of the gear 24 rotates the internal gears 22a, 22b and 22c around the hinge 21, The two doors 20 are opened.

このとき、ガイド溝１８の終端部によりガイドピン１９が保持され第一扉１０は完全に開く位置まで歯車１４を回転させ、第二扉の歯車群に回転力を伝達する。歯車２４の回転により内歯車２２ａを回動させ、内歯車の終端部まで回転した時には、ガイド溝２８ａの終端部にてガイドピン２９ｂが保持され、２２ｂが回動し始め歯車２４と噛み合い、第二扉の開放力を伝達する、同様に２２ｃが回動し第二扉を完全に開く位置まで開放する。   At this time, the guide pin 19 is held by the terminal portion of the guide groove 18, and the first door 10 rotates the gear 14 to the fully open position, and transmits the rotational force to the gear group of the second door. When the internal gear 22a is rotated by the rotation of the gear 24 and is rotated to the end portion of the internal gear, the guide pin 29b is held at the end portion of the guide groove 28a, and 22b starts to rotate and meshes with the gear 24. The opening force of the two doors is transmitted. Similarly, 22c rotates to open the second door to the fully open position.

また、第一扉１０を閉動作するときは、ガイド溝１８ａ及びガイド溝１８ｂの終端部によりガイドピン１９ｂ及びガイドピン１９ｃが保持されており内歯車１２ｃ及び内歯車１２ｂに反時計回り方向に回転力が生じ、歯車１４を従動する。内歯車１２ｂ及び内歯車１２ｃは、それぞれの終端部では、それ以上回動できなくなるとガイドピン１９ｂ及びガイドピン１９ｃは、ガイド溝１８ａ及びガイド溝１８ｂの終端の保持部分から開放され順次冷蔵庫内部に収納され、第一扉１０は閉状態にすることができる。このとき、歯車１４の回転は中間歯車及び第二扉２０の歯車群を介し、歯車２４を回転させる、前記歯車２４の回転は内歯車２２ｃに伝達され第二扉２０の扉閉力となる。内歯車２２ｃが冷蔵庫内部に完全に収納される時、ガイドピン２９ｃはガイド溝２８ｂの保持部分から脱し自由周動部分へと移動し、歯車２４の回転は内歯車２２ｂに伝達され第二扉２０を閉じる力となる。同様にして、歯車２４の回転は内歯車２２ａに伝達され、第二扉２０を完全に閉じることができる。   When the first door 10 is closed, the guide pin 19b and the guide pin 19c are held by the end portions of the guide groove 18a and the guide groove 18b, and rotate counterclockwise to the internal gear 12c and the internal gear 12b. A force is generated and the gear 14 is driven. When the internal gear 12b and the internal gear 12c can no longer be rotated at the respective end portions, the guide pin 19b and the guide pin 19c are released from the holding portions at the end of the guide groove 18a and the guide groove 18b and sequentially enter the refrigerator. The first door 10 can be closed when stored. At this time, the rotation of the gear 14 rotates the gear 24 via the intermediate gear and the gear group of the second door 20. The rotation of the gear 24 is transmitted to the internal gear 22 c and becomes the door closing force of the second door 20. When the internal gear 22c is completely housed in the refrigerator, the guide pin 29c moves away from the holding portion of the guide groove 28b and moves to the free peripheral movement portion, and the rotation of the gear 24 is transmitted to the internal gear 22b and transmitted to the second door 20. Power to close. Similarly, the rotation of the gear 24 is transmitted to the internal gear 22a, and the second door 20 can be completely closed.

以上の第一扉１０の開閉操作により第二扉２０が追従して開閉することを説明したが、第二扉２０の開閉操作により第一扉が追従することは言うまでもない。   Although it has been described that the second door 20 opens and closes by the opening and closing operation of the first door 10 described above, it goes without saying that the first door follows by the opening and closing operation of the second door 20.
