Description

【０００１】
【発明の属する技術分野】
本発明は、扉の開閉装置に関するものである。
【０００２】
【従来の技術】
従来、冷蔵庫の扉を閉める発明（例えば特許文献で）が開示されている。これは、図６に示すように区画室５３と前面区画棒に取り付けられる区画扉５０と、冷蔵庫庫内内方に向ってつば５２を形成したドア棚５４とから構成していた。すなわち、冷蔵庫庫内内方に向ってつば５２を形成したドア棚５４であるため、区画扉５０を開いた状態で冷蔵庫扉５４を閉めても、冷蔵庫扉５１と区画扉５０が当接する前に、つば５２が区画扉５０をはね上げることができる構成としていた（例えば特許文献１参照）。
【０００３】
【特許文献１】
特開平４−１７４２８３号公報
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の構成では、区画扉５０が９０°以上開いた状態で冷蔵庫扉５１を閉めようとすると区画扉５０がつば５２によりはね上げられず、また、冷蔵庫扉５１も閉まらず、また無理して閉めると破損をまねくという課題を有していた。
【０００５】
本発明はこのような従来の課題を解決するものであり、区画扉が９０°以上開いた状態で外郭扉を閉じた際、区画扉を外れる構成にし区画扉の閉め忘れを使用者に認識させる開閉装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記課題を解決するために、請求項１に記載の発明は、左右いずれかの端部に左右方向に回転する回転軸を有して外郭本体に着脱可能にて開閉するように設けられた第１の扉と、上端部に上下方向に回転する回転軸を有して前記第１の扉を覆う第２の扉と、前記第２の扉上で、かつ、前記第２の扉が閉動作時に前記第１の扉と対向する側に押しリブとを備え、前記第１の扉の全開時で、かつ、前記第２の扉の閉動作時に、前記第１の扉の上端部である一側面と当接する位置に前記押しリブが配設されるとともに、前記押しリブと前記一側面が当接してから、さらに前記第２の扉の閉動作を継続することで、前記押しリブによって前記一側面に外力が加わり、前記第１の扉が前記外郭本体から外れることを特徴とする。
【０００７】
上記第２の扉の押しリブによって、第１扉の一側面を押して回転軸を外郭本体から外すことが可能となり、第２扉の誤操作による閉動作時において第１の扉の閉め忘れ防止が得られる。
【０００８】
【発明の実施の形態】
以下本発明の実施の形態について空気調和機に例にして説明する。
【０００９】
（実施の形態１）
図１は空気調和機の室内ユニットで、前面グリルに相当する第２の扉２を開いた状態を示している。第２の扉の内部の本対側には電装部品の点検、操作などをするための第１の扉１が設けられている。
【００１０】
図２は、その第１の扉１近傍の拡大図で、第１の扉１が開いた状態を示している。図３は、第１の扉１を閉まった状態での方向から見た斜視図である。
【００１１】
第１の扉１には回転軸４ａ、４ｂが設けられ、この回転軸４ａ、４ｂが外郭本体面３の軸受け部８ａ、８ｂに回転自在に取りつけられて、第１の扉１が開閉できるようになっている。また第１の扉１が完全に開いた時に、外郭本体面３に当接する縦リブ５を設けている。
【００１２】
図４は図１のＡＡ断面であり、第１の扉１が完全に開いた状態を示している。第２の扉２の背面には、第１の扉１の側面１０に対応する位置に、所定長さの押しリブ９を設けている。この押しリブ９を図５に示す。
【００１３】
いま第１の扉１が完全に開いた状態で、第２の扉２を閉めようとした場合、押しリブ９の作用面９ａが第１の扉１の側面１０と接触し（図４の状態）、さらに第２の扉２を図４の矢印に示すように閉めていくと、押しリブ９の作用面９ａが第１の扉１の側面１０を斜め上方から押すように力が働き、その結果、回転軸4ａ、４ｂの台座６がたわみ、まず上方の回転軸４ａが軸受け部８ａから前方に外れ、そして下方の回転軸４ｂも外れて、第１の扉１は下方に脱落するようになっている。
【００１４】
また、下方の回転軸４ｂの長さを上方の回転軸４ａの長さより短くしておくと、上方の回転軸４ａが外れた後に、下方の回転軸４ｂだけで引っかかった状態になることなく下方の回転軸４ｂが容易に外れて脱落しやすいようにしている。
【００１５】
（実施の形態２）
また、本願の他の発明の実施例について説明する。
【００１６】
第１の扉１を上下方向に開閉するように取りつけた場合において、図５に示すように、第１の扉１の前面側に、短い縦リブ５ａを側面１１よりに設け、また第２の扉２の背面には、矢印に示すような位置（縦リブ５ａの反対側）に力がかかるように、押しリブ（図示せず）を設ければ、第２の扉が閉まるにしたがって、第１の扉がねじれを起こし、回転軸４aが外れるようになる。
【００１７】
以上のように、第1の扉１が開状態であるとき、第2の扉２を閉める際には、第1の扉１が外れることにより閉め忘れ防止を図ることができる。
【００１８】
【発明の効果】
上記から明らかなように、第１の扉が開状態であるとき、第２の扉を閉める際に、第２の扉の背面に設けた押しリブが、第１の扉の所定部分を押すことにより第１の扉の回転軸が外れ、外郭本体から第1の扉が脱落して、第１の扉の閉め忘れ防止を図ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a door opening and closing device.
[0002]
[Prior art]
Conventionally, the invention (for example, patent document) which closes the door of a refrigerator is disclosed. As shown in FIG. 6, this comprises a compartment door 50 attached to the compartment 53 and the front compartment bar, and a door shelf 54 in which a collar 52 is formed inward of the refrigerator. That is, since it is the door shelf 54 which formed the collar 52 toward the inside of the refrigerator cabinet, even if the refrigerator door 54 is closed with the compartment door 50 opened, the refrigerator door 51 and the compartment door 50 are not in contact with each other. The collar 52 is configured to be able to flip up the partition door 50 (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
JP-A-4-174283 [0004]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, if the refrigerator door 51 is to be closed with the compartment door 50 opened 90 ° or more, the compartment door 50 is not lifted up by the collar 52, and the refrigerator door 51 is not closed. When closed, it had the problem of causing damage.
[0005]
The present invention solves such a conventional problem, and when the outer door is closed with the partition door opened 90 ° or more, the user can recognize that the partition door has been forgotten to be closed when the outer door is closed. An object is to provide a switchgear.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 has a rotating shaft that rotates in the left-right direction at either one of the left and right ends, and is provided so as to be detachable from the outer shell body. 1 door, a second door that has a rotating shaft that rotates in the vertical direction at the upper end and covers the first door, and the second door is closed on the second door. A push rib is sometimes provided on the side facing the first door, and is a top end of the first door when the first door is fully opened and when the second door is closed. The push rib is disposed at a position in contact with the side surface, and after the press rib and the one side surface are in contact with each other, the closing operation of the second door is further continued, so that the first rib is pushed by the push rib. An external force is applied to the side surface, and the first door is detached from the outer body .
[0007]
The pushing rib of the second door makes it possible to push one side of the first door and remove the rotating shaft from the outer body. This prevents the first door from being forgotten to be closed when the second door is closed due to an erroneous operation. It is done.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described using an air conditioner as an example.
[0009]
(Embodiment 1)
FIG. 1 shows an indoor unit of an air conditioner in a state where a second door 2 corresponding to a front grille is opened. A first door 1 for inspecting and operating electrical parts is provided on the opposite side inside the second door.
[0010]
FIG. 2 is an enlarged view of the vicinity of the first door 1 and shows a state in which the first door 1 is opened. FIG. 3 is a perspective view of the first door 1 as viewed from the closed state.
[0011]
The first door 1 is provided with rotating shafts 4a and 4b. The rotating shafts 4a and 4b are rotatably attached to the bearing portions 8a and 8b of the outer shell main body surface 3 so that the first door 1 can be opened and closed. It has become. Moreover, when the 1st door 1 opens completely, the vertical rib 5 contact | abutted to the outer shell main body surface 3 is provided.
[0012]
FIG. 4 is a cross-sectional view taken along the line AA in FIG. 1 and shows a state where the first door 1 is completely opened. On the back surface of the second door 2, a push rib 9 having a predetermined length is provided at a position corresponding to the side surface 10 of the first door 1. This pushing rib 9 is shown in FIG.
[0013]
When the first door 1 is fully open and the second door 2 is to be closed, the action surface 9a of the push rib 9 comes into contact with the side surface 10 of the first door 1 (the state shown in FIG. 4). When the second door 2 is further closed as shown by the arrow in FIG. 4, a force acts so that the action surface 9 a of the push rib 9 pushes the side surface 10 of the first door 1 obliquely from above, As a result, the pedestal 6 of the rotating shafts 4a and 4b bends. First, the upper rotating shaft 4a is disengaged forward from the bearing portion 8a , and the lower rotating shaft 4b is also disengaged, so that the first door 1 drops downward. It has become.
[0014]
Further, if the length of the lower rotating shaft 4b is made shorter than the length of the upper rotating shaft 4a, the upper rotating shaft 4a is removed and the lower rotating shaft 4b is not caught by only the lower rotating shaft 4b. The rotating shaft 4b is easily detached and easily removed.
[0015]
(Embodiment 2)
Further, other embodiments of the present invention will be described.
[0016]
When the first door 1 is installed so as to open and close in the vertical direction, as shown in FIG. 5, a short vertical rib 5a is provided on the front side of the first door 1 from the side surface 11, and the second door 1 If a push rib (not shown) is provided on the rear surface of the door 2 so that a force is applied to the position indicated by the arrow (the opposite side of the vertical rib 5a), the second door is closed as the second door is closed. The door 1 is twisted and the rotating shaft 4a comes off.
[0017]
As described above, when the first door 1 is in the open state, when the second door 2 is closed, it is possible to prevent the first door 1 from being forgotten to be closed.
[0018]
【The invention's effect】
As is clear from the above, when the first door is in the open state, the push rib provided on the back surface of the second door pushes the predetermined portion of the first door when the second door is closed. As a result, the rotation axis of the first door is removed, and the first door is dropped from the outer shell body, thereby preventing the first door from being forgotten to be closed.
