【考案の詳細な説明】本考案は冷蔵庫本体の前面開口に備える扉に、さらに補
助扉を設けた冷蔵庫に関する。[Detailed Description of the Invention] The present invention relates to a refrigerator which further includes an auxiliary door in addition to the door provided at the front opening of the refrigerator main body.

一般に冷蔵庫の扉を開放すれば、その度に庫内の冷気漏
出、そして暖気侵入があり、貯蔵物品に悪影響を与えた
り、圧縮機の運転率を高めて使用電力量を多くする等の
欠点があり、そこで必要箇所の物品のみを取出し得るべ
く、主扉に対してさらに補助扉を設けることが知られて
；Ｇ）る。Generally, every time you open the refrigerator door, cold air leaks out and warm air enters the refrigerator, which has disadvantages such as adversely affecting stored items and increasing the operating rate of the compressor, increasing the amount of electricity used. Therefore, it is known that an auxiliary door is provided in addition to the main door in order to take out only the necessary items;G).

しかし、補助扉の開口部は構造上断熱壁を十分とれない
ため、開口部外周に露が付く欠点があり、外周部にヒー
タを入れて霜付を防止していだが、使用電力量の増加を
招く事になった。However, because the opening of the auxiliary door cannot have a sufficient insulating wall due to its structure, there is a drawback that dew forms on the outer periphery of the opening.Although a heater was installed around the outer periphery to prevent frost formation, this resulted in an increase in power consumption. I decided to invite him.

□そこで本考案はこのよう□な欠点を解消すべく簡
単な構造にて発汗防止を計るものであり、以下その一実
施例を添付図面に従い説明する。□Therefore, the present invention aims to prevent sweating with a simple structure in order to eliminate such □ drawbacks.One embodiment thereof will be described below with reference to the accompanying drawings.

図において、１は冷蔵庫本体を示し、本体１前面開口部
には上ヒンジ２、中ヒンジ３、下ヒンジ４によって冷凍
室扉５、冷蔵室主扉６（以下主扉と称す）が開閉自在に
装着されている。In the figure, 1 indicates the refrigerator main body, and the front opening of the main body 1 has a freezer compartment door 5 and a refrigerator compartment main door 6 (hereinafter referred to as the main door) that can be opened and closed by an upper hinge 2, a middle hinge 3, and a lower hinge 4. It is installed.

この主扉６は外板７、内板８、両板７，８間の断熱材９
より成り、内板８の両側には棚等を支持するための膨出
部１０が一体に形成されている。This main door 6 has an outer panel 7, an inner panel 8, and a heat insulating material 9 between both panels 7 and 8.
A bulge 10 for supporting a shelf or the like is integrally formed on both sides of the inner plate 8.

１１は主扉６の略下半分に両板７，８を接続する化粧枠
１２にて区画形成された取出口で、左右の膨出部１０の
巾と略等しい開口巾を有する。Reference numeral 11 denotes an outlet defined by a decorative frame 12 that connects both plates 7 and 8 to approximately the lower half of the main door 6, and has an opening width approximately equal to the width of the left and right bulges 10.

取出口１１には下端が枢支ピン１３にて支持され上端が
開閉する補助扉１４が備えられており、この補助扉１４
も主扉６と同じく外板１５と内板１６と断熱材１７にて
構成される。The outlet 11 is equipped with an auxiliary door 14 whose lower end is supported by a pivot pin 13 and whose upper end opens and closes.
Like the main door 6, it is also composed of an outer panel 15, an inner panel 16, and a heat insulating material 17.

１８は補助扉１４の裏面周縁に備えたガスケットで、化
粧枠１２の段部１２ａに吸着して開口部１４を密閉する
。A gasket 18 is provided on the periphery of the back surface of the auxiliary door 14, and is attracted to the stepped portion 12a of the decorative frame 12 to seal the opening 14.

１９は取出口１１に対向して左右の膨出部１０間にピン
２０にて回動自在に枢着した収容棚で、ピンＡ等を収納
する。Reference numeral 19 denotes a storage shelf that faces the outlet 11 and is rotatably pivoted between the left and right bulges 10 with a pin 20, and stores the pin A and the like.

そしてこの収容棚１９は補助扉１４の突出部１４′に常
時押圧されて扉１４の開放と同時に取出口１１側に傾刹
するようピン２０、棚１９の配置が決定されている。The arrangement of the pins 20 and the shelf 19 is determined so that the storage shelf 19 is always pressed by the protrusion 14' of the auxiliary door 14 and tilts toward the outlet 11 at the same time the door 14 is opened.

次に上記取出口１１部分をさらに詳述する。Next, the above-mentioned outlet 11 portion will be explained in more detail.

化粧枠１２は外板７の開口縁を被うフランジ１２ａと、
内板８の開口縁を接続すべく収納するよう形成された溝
１２ｂとを有し、また略中夫にはガスケット１８が当接
する段部１２ｃを形成している。The decorative frame 12 includes a flange 12a that covers the opening edge of the outer panel 7,
It has a groove 12b formed to accommodate and connect the opening edge of the inner plate 8, and a stepped portion 12c with which the gasket 18 abuts is formed substantially at the center shaft.

この化粧枠１２は鉄板等の熱伝導材料で戒り、一端が外
板７の裏面にスポット溶接（Ｐで示す）された補強枠２
１にて固定される。This decorative frame 12 is made of a heat conductive material such as an iron plate, and one end of the reinforcing frame 2 is spot-welded (indicated by P) to the back surface of the outer panel 7.
It is fixed at 1.

すなわちこの補強枠２１は上述の如く外板７裏面に当接
する当接部２１ａと化粧枠１２の段部１２ｃ裏面へ延出
して化粧枠１２と一体に形成されたボス部１２ｄに嵌合
しカップワッシャ２２並びにビス２３にて固定される固
定部２１ｂとを有する。That is, as described above, this reinforcing frame 21 fits into the contact portion 21a that contacts the back surface of the outer panel 7 and the boss portion 12d that extends to the back surface of the stepped portion 12c of the decorative frame 12 and is integrally formed with the decorative frame 12, thereby forming a cup. It has a washer 22 and a fixing part 21b fixed with a screw 23.

また外板７への補強枠２１のスポット溶接部Ｐは化粧枠
１２のフランジ１２ａ内に位置し、しかも当接部２１ａ
はフランジ１２ａの端面より十分外方へ延出するようそ
の長さが設定されている。Further, the spot welding portion P of the reinforcing frame 21 to the outer panel 7 is located within the flange 12a of the decorative frame 12, and the contact portion 21a
The length is set so as to extend sufficiently outward from the end face of the flange 12a.

すなわち、当接部２１ａがフランジ１２ａより十分延出
していることで室内温度とほぼ等しくなっている外板７
の温度を補強枠２１を介して化粧枠１２に伝導するもの
で、庫内の低温度に影響されやすい化粧枠１２を外気温
（室内温度）近くまで上昇せしめ、よって、化粧枠１２
への発汗を防止することができるものである。In other words, the outer plate 7 has a contact portion 21a that extends sufficiently beyond the flange 12a, so that the temperature is almost equal to the indoor temperature.
temperature is conducted to the decorative frame 12 via the reinforcing frame 21, and the decorative frame 12, which is easily affected by the low temperature inside the refrigerator, is raised to near the outside temperature (indoor temperature).
It can prevent sweating.

またフランジ１２ａによってスポット溶接部ｐを外部に
露見しない。Furthermore, the spot weld p is not exposed to the outside due to the flange 12a.

以上の説明からも明らかな如く、主扉の取出口を形成す
る化粧枠の発汗を、化粧枠を固定する補強枠が主扉の外
板から熱伝導し得るよう構成したものであるから、別途
発汗防止部材やヒータ等を必要とせず、組立が簡単にな
り、省電力にも寄与できるものである。As is clear from the above explanation, the reinforcing frame that fixes the decorative frame is configured to conduct heat from the decorative frame that forms the outlet of the main door from the outer panel of the main door, so it is necessary to separately It does not require a sweat prevention member, a heater, etc., simplifies assembly, and contributes to power savings.
