Description

【０００１】
【発明の属する技術分野】
本発明は、観音開き式の冷蔵庫、冷凍庫、温蔵庫等各種の貯蔵庫に関する。
【０００２】
【従来の技術】
貯蔵庫は、その一例である観音開き式冷蔵庫として、例えば特開昭５８−１５３０７２号公報に示されているように、正面開口部を有する庫本体と、同庫本体の正面開口部の各側縁部に基端部を前後方向へ回動可能に組付けられて同庫本体の正面開口部を開閉する左右一対の開閉扉を備え、前記両開閉扉の閉鎖時、前記各開閉扉の背面側周縁部を庫本体の正面開口部の周縁部に当接させて、両開閉扉の背面と庫本体の正面開口部の周縁部間をシールする構成となっている。
【０００３】
かかる形式の貯蔵庫においては、両開閉扉の背面と庫本体の正面開口部の周縁部間におけるシール部の気密性を確保するために、各開閉扉の背面の基端側縁部、上端縁部、および下端縁部にそれぞれマグネット付きの側縁側ドアパッキン、上端側ドアパッキン、および下端側ドアパッキンを設け、また、両開閉扉の互いに対向する先端部間の気密性を確保するために、両開閉扉の互いに対向する先端部にマグネット付きの先端側ドアパッキンを設けて、両開閉扉の閉鎖時、各ドアパッキンを庫本体の正面開口部の周縁部に密着させて、両開閉扉の背面と庫本体の正面開口部の周縁部間を気密的にシールするとともに、両開閉扉の先端側ドアパッキンを互いに気密的にシールするように構成されている。
【０００４】
【発明が解決しようとする課題】
かかる形式の貯蔵庫においては、両開閉扉の閉鎖時には、開閉扉が円滑に回動して、その背面側のドアパッキンを基端部側から庫本体の周縁部に漸次当接して密着するようにすることが必要であり、かつ、両開閉扉の先端側ドアパッキン同士が互いの対向面にて的確に当接して密着することが必要である。これにより、両開閉扉の閉鎖時における庫本体の正面開口部の的確な密閉状態が確保される。
【０００５】
従って、本発明の目的は、上記した片開き式貯蔵庫、および観音開き式貯蔵庫におけるこのような要求に対処することにある。
【０００６】
【課題を解決するための手段】
本発明は貯蔵庫に関し、特に、正面開口部を有する庫本体における正面開口部の左右の各側縁部に基端部を前後方向へ回動可能に組付けられて同庫本体の正面開口部を開閉する左右一対の開閉扉を備え、前記各開閉扉の背面における基端側縁部および上下各端縁部にマグネット付きの側縁側ドアパッキン、マグネット付きの上端側ドアパッキン、およびマグネット付きの下端側ドアパッキンを備えるとともに、前記各開閉扉の互いに対向する先端部に互いに対向するマグネット付きの先端側ドアパッキンを備え、前記両開閉扉の閉鎖時、前記側縁側ドアパッキン、上端側ドアパッキンおよび下端側ドアパッキンを前記庫本体の正面開口部の周縁部に密着させ、かつ、前記両先端側ドアパッキンを互いに密着させて、前記両開閉扉の背面と前記庫本体の正面開口部の周縁部間、および、前記両開閉扉の先端部間を気密的にシールする形式の観音開き式の貯蔵庫を適用対象とするものである。
【０００７】
しかして、本発明は上記した形式の観音開き式の貯蔵庫において、前記上端側ドアパッキンおよび下端側ドアパッキンの磁力を前記側縁側ドアパッキンおよび前記先端側ドアパッキンの磁力に比較して相対的に強く設定したことを特徴とするものである。
【０００８】
本発明に係る貯蔵庫は、冷蔵庫として構成することが好ましい。
【０００９】
【発明の作用・効果】
このように構成した貯蔵庫においては、両開閉扉の閉鎖時には、両開閉扉の各ドアパッキンにおいては、開閉扉の基端側の側縁側ドアパッキンが先に庫本体の正面開口部の周縁部に当接し、その後、上端側ドアパッキンおよび下端側ドアパッキンがその基端部側から庫本体の正面開口部の周縁部に漸次当接して、開閉扉の閉鎖完了時には、これらのドアパッキンの全てが庫本体の正面開口部の周縁部に密着するとともに、両開閉扉の先端側ドアパッキンが互いの対向面にて当接して密着する。
【００１０】
この場合、側縁側ドアパッキンの磁力は上端側ドアパッキンおよび下端側ドアパッキンの磁力に比較して相対的に弱く設定されているため、側縁側ドアパッキンは、上端側ドアパッキンおよび下端側ドアパッキンが庫本体の正面開口部の周縁部に当接する際には、弱い吸引力で庫本体の正面開口部の周縁部に正常な形態を保持して当接して噛み込むようなことがなく、開閉扉の円滑な回動動作を維持する。
【００１１】
また、その後の開閉扉の回動（閉鎖）操作により上端側ドアパッキンおよび下端側ドアパッキンがその基端部側から庫本体の正面開口部の周縁部に漸次当接するが、上端側ドアパッキンおよび下端側ドアパッキンは、その磁力が側縁側ドアパッキンの磁力に比較して相対的に強く設定されているため、庫本体の正面開口部の周縁部に正常な形態で漸次当接して密着し、開閉扉は円滑に閉鎖されて密閉される。
【００１２】
両開閉扉が閉鎖される際には、両開閉扉の先端側ドアパッキンは、それらの対向面を互いに密着させて両開閉扉の先端部間を気密的にシールするが、この場合には、上端側ドアパッキンおよび下端側ドアパッキンの強い吸引力が両先端側ドアパッキンの当接を助成して密着状態を形成し、両開閉扉の先端部間のシール部の気密性を、センタピラー等の支持部材を介することなく、確実なものとすることができる。
【００１３】
【発明の実施の形態】
以下、本発明を図面に基づいて説明すると、図１には本発明に係る観音開き式貯蔵の一例である観音開き式冷蔵庫の一例が示されている。冷蔵庫は、図１〜図３に示すように、正面開口部１１を有する庫本体１０と、庫本体１０の正面開口部１１の各側縁部に基端部を前後方向へ回動可能に組付けられて庫本体１０の正面開口部１１を開閉する上側の左右一対の開閉扉２０ａ、２０ｂと、下側の左右一対の開閉扉２０ｃ，２０ｄを備え、これらの４枚の開閉扉２０ａ〜２０ｄの開閉操作により、庫本体１０の正面開口部１１を開放し、かつ閉鎖し得るように構成されている。
【００１４】
上側の各開閉扉２０ａ，２０ｂは互に左右対称に、下側の各開閉扉２０ｃ，２０ｄは互に左右対称に、かつ、左側の各開閉扉２０ａ、２０ｃは互に上下対称に、右側の各開閉扉２０ｂ，２０ｄは互に上下対称に形成されている点を除き、全て同一構造に構成されている。従って、以下では、各開閉扉２０ａ〜２０ｄの構成については主として開閉扉２０ａに基づいて説明し、各開閉扉２０ａ〜２０ｄ相互の関係については必要により説明するに止める。
【００１５】
開閉扉２０ａは、図２および図３に示すように、扉本体２１の背面における周縁部に第１のドアパッキン２２が配設されているとともに、扉本体２１の背面における先端部側に第２のドアパッキン２３が配設されている。第１，第２のドアパッキン２２，２３は共に、ゴム製のパッキン本体にマグネットを内蔵させたのものである。
【００１６】
第１のドアパッキン２２はコ字状を呈しているもので、扉本体２１の背面にてその基端部側に位置する側縁側ドアパッキン２２ａと、上端側ドアパッキン２２ｂと、下端側ドアパッキン２２ｃにて構成されている。第２のドアパッキン２３は、上下方向に延びる直線状のもので、支持部材２４に支持された状態で配設されて、扉本体２１の背面における先端部側に位置して、第１のドアパッキン２２の上端側ドアパッキン２２ｂと、下端側ドアパッキン２２ｃの各端部に達している。
【００１７】
これにより、開閉扉２０ａの閉鎖時には、第１のドアパッキン２２は庫本体１０の正面開口部１１の周縁部に当接する。同様に、開閉扉２０ｂの閉鎖時には、第１のドアパッキン２２は庫本体１０の正面開口部１１の周縁部に当接するとともに、第２のドアパッキン２３が開閉扉２０ａの第２のドアパッキン２３と密着して、両開閉扉２０ａ，２０ｂ間をシールする。下側の左右の開閉扉２０ｃ，２０ｄにおいても同様に閉鎖され、庫本体１０の正面開口部１１が密閉状態に閉鎖される。
【００１８】
しかして、第１のドアパッキン２２においては、上端側ドアパッキン２２ｂおよび下端側ドアパッキン２２ｃの磁力を側縁側ドアパッキン２２ａの磁力に比較して相対的に強く設定されていて、庫本体１０の正面開口部１１の周縁部に対する吸着力が側縁側ドアパッキン２２ａでは弱く、上端側ドアパッキン２２ｂおよび下端側ドアパッキン２２ｃが強く構成されている。
【００１９】
一方、第２のドアパッキン２３においては、第１のドアパッキン２２を構成する側縁側ドアパッキン２２ａの磁力と同等に設定されていて、図４に示すように、支持部材２４に支持されていて、支持部材２４を介して開閉扉２０ａ，２０ｂに取付けられている。第２のドアパッキン２３は、支持部材２４の先端側に組付けられた状態で、開閉扉２０ａ，２０ｂの先端側に突出していて、両開閉扉２０ａ，２０ｂの閉鎖時には、互いに当接して密着するようになっている。下側の両開閉扉２０ｃ，２０ｄにおいても、第２のドアパッキン２３が同様の組付け状態で組付けられている。
【００２０】
このように構成した観音開き式冷蔵庫においては、全ての開閉扉２０ａ〜２０ｄを閉鎖した状態では、図２〜図４に示すように、各開閉扉２０ａ〜２０ｄの背面に設けた第１のドアパッキン２２が庫本体１０の正面開口部１１の周縁部に密着するとともに、上側の両開閉扉２０ａ，２０ｂに設けた第２のドアパッキン２３同士、および下側の両開閉扉２０ｃ，２０ｄに設けた第２のドアパッキン２３同士がその先端部の対向面にて密着し、庫本体１０の正面開口部１１を密閉する。
【００２１】
図４は、左右の両開閉扉２０ａ，２０ｂを閉鎖した場合の両開閉扉２０ａ，２０ｂ間のシール状態を示すもので、この閉鎖状態においては、両開閉扉２０ａ，２０ｂに設けた第２の各ドアパッキン２３は、ピラーカバー２６の先端部２６ａと支持部材２４のカバー体２４ａとにより、それらの前側および後側を覆蓋されており、ヒータ２５からピラーカバー２６を介して伝達される熱により、凍結および結露を防止されている。
【００２２】
また、両開閉扉２０ａ，２０ｂの第２のドアパッキン２３は、埋設されているマグネット２３ａの吸引力にてその対向面を密着させて、庫本体１０の正面開口部１１からの冷気の漏洩を防止している。なお、下側の左右の両開閉扉２０ｃ，２０ｄの閉鎖状態も同様である。
【００２３】
ところで、当該観音開き式冷蔵庫においては、各開閉扉の閉鎖時には、開閉扉の第１のドアパッキン２２においては、開閉扉の基端側の側縁側ドアパッキン２２ａが先に庫本体１０の正面開口部１１の周縁部に当接し、その後、上端側ドアパッキン２２ａおよび下端側ドアパッキン２２ｂがその基端部側から庫本体１０の正面開口部１１の周縁部に漸次当接して、開閉扉の閉鎖完了時には全てのドアパッキン２２ａ，２２ｂ，２２ｃが庫本体１０の正面開口部１１の周縁部に密着する。
【００２４】
この場合、側縁側ドアパッキン２２ａの磁力は上端側ドアパッキン２２ｂおよび下端側ドアパッキン２２ｃの磁力に比較して相対的に弱く設定されているため、側縁側ドアパッキン２２ａは、上端側ドアパッキン２２ｂおよび下端側ドアパッキン２２ｃが庫本体１０の正面開口部１１の周縁部に当接する際には、弱い吸引力で庫本体１０の正面開口部１１の周縁部に正常な形態を保持して当接して噛み込むようなことがなく、開閉扉の円滑な回動動作を維持する。
【００２５】
また、その後の開閉扉の回動（閉鎖）操作により、上端側ドアパッキン２２ｂおよび下端側ドアパッキン２２ｃがその基端部側から庫本体１０の正面開口部１１の周縁部に漸次当接して密着するが、上端側ドアパッキン２２ｂおよび下端側ドアパッキン２２ｃは、その磁力が側縁側ドアパッキン２２ａの磁力に比較して相対的に強く設定されているため、庫本体１０の正面開口部１１の周縁部に漸次当接し、開閉扉は円滑に閉鎖されて密閉される。
【００２６】
また、当該観音開き式冷蔵庫においては、各開閉扉の互いに対向する先端部側に同先端部に沿って上下方向に延びる第２のドアパッキン２３を設けて、両開閉扉の閉鎖時、第２のドアパッキン２３の対向面を互いに密着させて両開閉扉の先端部間を気密的にシールするように構成している。この場合には、上端側ドアパッキン２２ｂおよび下端側ドアパッキン２２ｃの強い吸引力が第２のドアパッキン２３の当接を助成して密着状態を形成し、両開閉扉の先端部間のシール部の気密性を確実なものとする。
【００２７】
なお、以上の構成は観音開き式の冷凍庫に関するものであるが、本発明はこのような冷蔵庫に限らず、冷凍庫、温蔵庫等、各種の観音開き式貯蔵庫に対しても同様に適用することができる。

The part is brought into contact with the peripheral edge of the front opening of the storage body, and the space between the rear surfaces of the two doors and the peripheral edge of the front opening of the storage main body is sealed.
[0003]
In this type of storage, in order to ensure the airtightness of the seal portion between the back of both doors and the peripheral edge of the front opening of the main body, the base end side edge and the top edge of the back of each door In addition, side edge side door packing with magnets, upper end side door packing, and lower end side door packing are provided at the lower end edges, respectively, and in order to ensure airtightness between the opposite end portions of both opening and closing doors, Front door seals with magnets are provided at the opposite ends of the doors, and when both doors are closed, each door packing is brought into close contact with the peripheral edge of the front opening of the cabinet body, And the peripheral edge portion of the front opening of the storage body are hermetically sealed, and the front end side door packings of both opening and closing doors are hermetically sealed .
[0004]
[Problems to be solved by the invention]
In such a type of storage, when both the doors are closed, the doors rotate smoothly so that the door packing on the back side gradually contacts the peripheral edge of the storage body from the base end side. In addition, it is necessary for the front end side door packings of both the open / close doors to be in close contact with each other on the opposing surfaces. Thus, accurate sealing state of the front opening of the refrigerator body at the time of closure of the two door is ensured.
[0005]
Accordingly, an object of the present invention is to cope with such a requirement in the above-described single-opening storage and double door-opening storage.
[0006]
[Means for Solving the Problems]
The present invention relates to a reservoir, in particular, a front opening of the refrigerator body assembled to be rotatable back and forth direction base end to a respective side edge portions of the left and right front opening in the cabinet main body having a front opening A pair of left and right open / close doors that opens and closes, a base side edge on the back of each open / close door, and a side edge side door packing with a magnet on each of the upper and lower end edges, an upper end side door packing with a magnet, and a lower end with a magnet A side door packing, and a front end side door packing with magnets facing each other at the front ends facing each other , and when the both opening and closing doors are closed, the side edge side door packing, the upper end side door packing, and The lower end side door packing is brought into close contact with the peripheral edge of the front opening of the main body, and the both end side door packings are brought into close contact with each other, and Between the periphery of the front opening of the body, and is intended to the double doors type reservoir of the type to hermetically seal between the tip portion of the two door and applied.
[0007]
Thus, the present invention is a double door storage of the type described above, wherein the magnetic force of the upper end side door packing and the lower end side door packing is relatively stronger than the magnetic force of the side edge side door packing and the front end side door packing. It is characterized by setting.
[0008]

Since the lower end side door packing is relatively strong compared to the magnetic force of the side edge side door packing, the lower end side door packing gradually comes into close contact with the peripheral edge of the front opening of the main body in a normal form, The open / close door is smoothly closed and sealed.
[0012]
When both door is closed, the tip-side door packing of both door is brought into close contact with their opposing surfaces to each other air-tightly seal between the tip portions of the opening and closing door, but in this case, strong suction force of the upper end-side door packing and lower side door packing to assist in abutment of both the tip side door gasket to form a close contact, the air-tightness of the seal portion between the distal end portions of the door, a center pillar or the like It can be assured without using a support member.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 shows an example of a double door refrigerator which is an example of a double door storage according to the present invention. As shown in FIGS. 1 to 3, the refrigerator is configured such that a base body 10 having a front opening 11 and a base end portion of each side edge of the front opening 11 of the storage body 10 can be rotated in the front-rear direction. A pair of upper left and right open / close doors 20a and 20b attached to open and close the front opening 11 of the main body 10 and a pair of lower left and right open / close doors 20c and 20d are provided, and these four doors 20a to 20d are provided. The front opening 11 of the cabinet body 10 can be opened and closed by the opening / closing operation.
[0014]
The upper doors 20a, 20b are symmetrical with each other, the lower doors 20c, 20d are symmetrical with each other, and the left doors 20a, 20c are vertically symmetrical with each other. Each of the open / close doors 20b and 20d has the same structure except that they are formed symmetrically with respect to each other. Therefore, hereinafter, the configuration of each of the open / close doors 20a to 20d will be described mainly based on the open / close door 20a, and the relationship between the open / close doors 20a to 20d will be described only if necessary.
[0015]
As shown in FIGS. 2 and 3, the opening / closing door 20 a is provided with a first door packing 22 at the peripheral edge portion on the back surface of the door body 21, and at the front end portion side on the back surface of the door body 21. Door packing 23 is provided. Both the first and second door packings 22 and 23 are made by incorporating a magnet in a rubber packing body.

The second door packings 23 are in close contact with each other at the front surface of the front end portion, and the front opening 11 of the main body 10 is sealed.
[0021]
FIG. 4 shows a sealed state between the two doors 20a and 20b when the left and right doors 20a and 20b are closed. In this closed state, the second doors 20a and 20b provided with the second doors 20a and 20b are closed. Each door packing 23 is covered by a front end portion 26a of the pillar cover 26 and a cover body 24a of the support member 24, and the heat and the heat transmitted from the heater 25 through the pillar cover 26 are covered. Freezing and condensation are prevented.
[0022]
Further, the second door packing 23 of both the open / close doors 20a, 20b is brought into close contact with the attracting force of the embedded magnet 23a so that the cold air leaks from the front opening 11 of the box body 10. It is preventing. The same applies to the closed state of the left and right open / close doors 20c, 20d on the lower side.
[0023]
By the way, in the double door type refrigerator, when each door is closed, in the first door packing 22 of the opening / closing door, the side edge side door packing 22a on the base end side of the opening / closing door is the front opening of the main body 10 first. 11 and then the upper end side door packing 22a and the lower end side door packing 22b gradually come into contact with the peripheral edge portion of the front opening 11 of the main body 10 from the base end side to complete the closing of the door. Sometimes all the door packings 22 a, 22 b, 22 c are in close contact with the peripheral edge of the front opening 11 of the cabinet body 10.
[0024]
In this case, since the magnetic force of the side edge side door packing 22a is set relatively weak compared to the magnetic force of the upper end side door packing 22b and the lower end side door packing 22c, the side edge side door packing 22a is the upper end side door packing 22b. When the lower end side door packing 22c comes into contact with the peripheral edge portion of the front opening 11 of the main body 10, the normal form is held in contact with the peripheral portion of the front opening 11 of the main body 10 with a weak suction force. The opening / closing door can be smoothly rotated without being bitten.
[0025]
Further, by the subsequent turning (closing) operation of the door, the upper end door packing 22b and the lower end door packing 22c are gradually brought into close contact with the peripheral edge portion of the front opening 11 of the main body 10 from the base end side. However, since the magnetic force of the upper end side door packing 22b and the lower end side door packing 22c is set relatively stronger than the magnetic force of the side edge side door packing 22a, the peripheral edge of the front opening 11 of the case body 10 The opening / closing door is smoothly closed and sealed.
[0026]
Further, in the double door open refrigerator, the second door packing 23 extending in the vertical direction along the front end portion is provided on the front end portions facing each other of the open / close doors. The opposing surfaces of the door packing 23 are brought into close contact with each other so as to hermetically seal between the front ends of both the doors. In this case, the strong suction force of the upper end side door packing 22b and the lower end side door packing 22c assists the contact of the second door packing 23 to form a close contact state, and a seal portion between the front end portions of the both opening and closing doors. The airtightness of the is ensured.
[0027]
In addition, although the above structure is related with a double-opening type freezer, the present invention is not limited to such a refrigerator, but can be similarly applied to various double-opening storages such as a freezer and a warm storage. .
