Description

本発明は冷蔵庫に関する。   The present invention relates to a refrigerator.

最上段を冷凍室とする多数段の貯蔵室を有する冷蔵庫では、冷凍室前面を回転式の扉で閉塞するものが知られており、この冷凍室に製氷皿が配置されたものとしては、例えば、特許文献1乃至3に記載のものがある。   In a refrigerator having a multi-stage storage room with the uppermost stage being a freezing room, it is known that the front of the freezing room is closed with a rotary door, and an ice tray is arranged in this freezing room, for example, Patent Documents 1 to 3 are available.

このような構成の冷蔵庫について図9を用いて説明する。図9は、最上段を冷凍室として多数段の貯蔵室を有する従来の冷蔵庫を示すものである。冷蔵庫1は、多数段の貯蔵室を備えてなり、最上段に冷凍室2を、下段に冷蔵室8、9を有する。冷凍室2は回転式の扉3でその前面が閉塞され、冷凍室2内には屋根つきの部材5で上面及び側面が囲まれる製氷空間内に製氷皿4が配される。また、氷をストックするために別の収納容器6を備えるものもある。   A refrigerator having such a configuration will be described with reference to FIG. FIG. 9 shows a conventional refrigerator having a multi-stage storage room with the uppermost stage being a freezing room. The refrigerator 1 includes a multi-stage storage room, and has a freezing room 2 at the top and refrigeration rooms 8 and 9 at the bottom. The freezer compartment 2 is closed at its front by a rotary door 3, and an ice tray 4 is arranged in the ice compartment where the upper surface and side surfaces are surrounded by a member 5 with a roof. Some have a separate storage container 6 for stocking ice.

これらの製氷皿4、屋根つきの部材5及び収納容器6の奥行方向の長さは、扉3が閉じられたときに、扉3の内側部7と干渉することを防ぐために、冷凍室2内の奥行方向より小さな寸法で形成される。   The length of the ice tray 4, the roofed member 5 and the storage container 6 in the depth direction is such that when the door 3 is closed, the length in the freezer compartment 2 can be prevented from interfering with the inner portion 7 of the door 3. It is formed with dimensions smaller than the depth direction.

特開平4−20772号公報(図1)JP-A-4-20772 (FIG. 1)

特開平5−34058号公報(図1)JP-A-5-34058 (FIG. 1) 特開平5−256564号公報(図1)JP-A-5-256564 (FIG. 1)

上記の従来技術のような、回転式扉によって閉塞された貯蔵室内に引き出し式の収納容器(製氷皿)を配置するという構成の場合には、以下のような点で問題があった。   In the case of a configuration in which a drawer-type storage container (ice tray) is arranged in a storage chamber closed by a rotary door as in the above-described prior art, there are problems in the following points.

すなわち、この種の冷凍室においては、扉の支持部側の収納物(製氷皿)を取り出す際には、扉を全開に開かないと冷凍室内の収納物(製氷皿)を取り出すことは容易ではなかった。更に、扉を全開で引出すことで庫内の冷気が庫外への流出する量が多く、効率の悪くなり、省エネという観点からも問題があった。   That is, in this type of freezer compartment, when taking out the stored item (ice tray) on the support portion side of the door, it is not easy to take out the stored item (ice tray) in the freezer compartment unless the door is fully opened. There wasn't. Furthermore, when the door is fully opened, the amount of cool air inside the warehouse flows out to the outside of the warehouse, resulting in inefficiency and a problem in terms of energy saving.

扉の支持部側の収納物を取り出す際に、扉を全開に開かないと冷凍室内の収納物(製氷皿)を容易に取り出すことは出来なかった。また、扉を全開に開くことにより、冷凍室内の冷気の流出が必要以上の量であった。換言すると、収納物の位置が、扉の支持部の位置に関わらず、何処の収納物の位置でも、流出される冷気量は殆ど同じであった。   When taking out the stored item on the support part side of the door, the stored item (ice tray) in the freezer compartment could not be easily taken out unless the door was fully opened. Moreover, by opening the door fully open, the outflow of cold air in the freezer compartment was more than necessary. In other words, the amount of cool air that flows out is almost the same regardless of the position of the stored item regardless of the position of the support part of the door.

また、この収納容器は、内容積を出来るだけ多く確保することが望まれるため、冷凍室内の奥行方向より僅か小さな寸法で形成されていることから、収納容器は前後方向にはスライドするものの、スライドする距離が長く、収納容器の奥側にある収納物は、一旦、収納容器を取り出すか、手を奥まで伸ばして取り出すなどの余分な動作をユーザーに強いることがある等、収納物を手早く取り出すことへの配慮にかけていた。   In addition, since it is desired that the storage container has as much internal volume as possible, the storage container is formed with a size slightly smaller than the depth direction in the freezer compartment. For items stored on the far side of the storage container, take out the storage container quickly, such as temporarily removing the storage container or forcing the user to take extra actions such as extending the hand to the back. I was concerned about that.

本発明は、上記のような問題点に艦みてなされたものであり、省エネに配慮し、収納物を手早く取り出すことが可能な冷蔵庫を提供することを目的とするものである。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a refrigerator capable of quickly taking out stored items in consideration of energy saving.

本発明によれば、省エネに配慮し、収納物を手早く取り出すことが可能な冷蔵庫を提供することができる。   According to the present invention, it is possible to provide a refrigerator capable of quickly taking out stored items in consideration of energy saving.

以下、本発明の実施形態について図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図1は本発明の一実施形態に係る冷蔵庫正面図である。この冷蔵庫は図1に示すように上段に冷凍室10、下段に冷蔵室11を配設させている。冷凍室扉12は、冷凍室10前面開口部を開閉するように設けられ、冷蔵庫の左右の少なくともいずれかの側端部(この実施例では右側端部)に設けられた支持部13により支持され、水平方向に回動可能な回転式の扉である。   FIG. 1 is a front view of a refrigerator according to an embodiment of the present invention. As shown in FIG. 1, this refrigerator has a freezer compartment 10 in the upper stage and a refrigerator room 11 in the lower stage. The freezer compartment door 12 is provided so as to open and close the front opening of the freezer compartment 10, and is supported by a support portion 13 provided on at least one of the left and right side ends (right end portion in this embodiment) of the refrigerator. The rotary door is rotatable in the horizontal direction.

また、冷凍室扉12は冷凍室10前面全体を開閉する主扉14と、この主扉14の一部に設けた補助開口部15を開閉する補助扉16とを有している。   The freezer compartment door 12 has a main door 14 that opens and closes the entire front surface of the freezer compartment 10, and an auxiliary door 16 that opens and closes an auxiliary opening 15 provided in a part of the main door 14.

主扉は、水平方向に回動して冷凍室10を開閉するように側端部を支持する支持部13と、主扉14の支持部側最下部に、補助扉開口を形成した補助開口部15と、支持部13の反対側に設けられた主扉取手部17を有している。   The main door pivots in the horizontal direction to support the side end so as to open and close the freezer compartment 10 and an auxiliary opening formed with an auxiliary door opening at the lowermost support side of the main door 14 15 and a main door handle portion 17 provided on the opposite side of the support portion 13.

補助扉16は、主扉14の補助開口部15を開閉するように水平方向に回動可能に支持し、且つ、主扉14の支持部13と同じ側の側端部を支持する支持部18と、支持部18と反対側の下部に設けられた補助扉取手部19を有している。   The auxiliary door 16 is supported so as to be rotatable in the horizontal direction so as to open and close the auxiliary opening 15 of the main door 14, and supports the side end of the main door 14 on the same side as the support 13. And an auxiliary door handle 19 provided at the lower part opposite to the support 18.

このように、補助扉16は主扉14の支持部側で、しかも最下部に位置しているが、補助扉16の配置は必要に応じ、どこの場所に配置しても本発明は有効である。   As described above, the auxiliary door 16 is located on the support portion side of the main door 14 and at the lowest position. However, the auxiliary door 16 can be disposed anywhere as necessary. is there.

しかし、ユーザーの使い勝手を考慮すると、前記の如く、主扉14の支持部側で、しかも最下部に配置している方が、通常取り出し難い扉の支持部側の収納物の取り出しに有効であり、最上段に配設している冷凍室であるが故、極力低い位置に補助扉開口部15を設けた方が、使い勝手が良くなるのである。   However, considering user convenience, as described above, it is more effective to take out the stored items on the support side of the door, which is difficult to take out, if it is arranged on the support side of the main door 14 and at the bottom. Since it is the freezer compartment arranged in the uppermost stage, it is more convenient to provide the auxiliary door opening 15 at a position as low as possible.

次に冷凍室10の構造について、図2を参照にして説明する。
10は冷凍室で、背面側には蒸発器20や蒸発器ファン21を有する冷却室22が配置され、前面側には冷凍室10の前面開口部を閉塞する主扉14と補助扉16を有する冷凍室扉12を配置している。蒸発器20は、図示にはないが、圧縮機、凝縮器、減圧装置などと共に冷凍サイクルを構成しており、この蒸発器20で冷媒が蒸発した際に周囲の空気温度が下がり冷却空気となり蒸発器ファン21の駆動に伴い冷凍室10や冷蔵室11に供給される。
Next, the structure of the freezer compartment 10 will be described with reference to FIG.
Reference numeral 10 denotes a freezer compartment, a cooling chamber 22 having an evaporator 20 and an evaporator fan 21 is arranged on the back side, and a main door 14 and an auxiliary door 16 that close the front opening of the freezer compartment 10 are arranged on the front side. A freezer compartment door 12 is arranged. Although not shown in the figure, the evaporator 20 forms a refrigeration cycle together with a compressor, a condenser, a decompression device, and the like. When the refrigerant evaporates in the evaporator 20, the temperature of the surrounding air is lowered and becomes cooling air to evaporate The freezer 10 and the refrigerator 11 are supplied as the fan 21 is driven.

23は自動製氷機であり、その内部に製氷皿23aと、製氷皿23aを動作させる機械部23bと製氷された氷を貯める貯氷容器24と、貯氷容器24を支持すると共に前方に引出し可能とする貯氷容器受25を備えている。   An automatic ice maker 23 includes an ice tray 23a, a mechanical unit 23b for operating the ice tray 23a, an ice storage container 24 for storing iced ice, and an ice storage container 24 that can be pulled forward. An ice storage container receiver 25 is provided.

補助扉16には、扉背面から後方に突出して貯氷容器受25の底部前端凹部25aと係合する合成樹脂製の扉側係合部材26が取付けられている。   A synthetic resin door side engaging member 26 that protrudes rearward from the door rear surface and engages with the bottom front end recessed portion 25 a of the ice storage container receiver 25 is attached to the auxiliary door 16.

この扉側係合部材26は、扉背面を形成する薄肉樹脂性の扉内側材27に、ネジ等により取付けられた係合部材固定具28に設けられた丸穴28aに係止され、その取付位置は、扉回転軸寄りの扉背面下端部設定されている。扉側係合部材26は、棒状の後方延設部26aと、後方延設部の先端に設けられた上方に突出する水平断面形の係合ピン26bよりなる。更に、係合部材26と係合部材固定具28との係止する箇所を回転軸とした弾性部材29を内部に有している。   The door-side engagement member 26 is locked to a round hole 28a provided in the engagement member fixture 28 attached to the thin resin door inner material 27 forming the rear surface of the door by screws or the like. The position is set at the lower end of the door rear surface near the door rotation axis. The door-side engaging member 26 includes a rod-like rearward extending portion 26a and an engaging pin 26b having a horizontal cross section projecting upward provided at the tip of the rearward extending portion. Further, an elastic member 29 having a portion where the engaging member 26 and the engaging member fixture 28 are locked as a rotation shaft is provided inside.

貯氷容器24は、上方に開口する水平断面が概略矩形をなす有底箱状の容器である。
25は貯氷容器を支持する貯氷容器受であり、自動製氷機23外壁に設けられた支持部30によりその底面が支えられている。また、貯氷容器受け25前面下部には、扉側系合部材26の係合ピン26bと係合する係合凹部25aを有している。
The ice storage container 24 is a bottomed box-shaped container in which a horizontal cross section that opens upward is substantially rectangular.
An ice storage container receiver 25 supports the ice storage container, and the bottom surface thereof is supported by a support portion 30 provided on the outer wall of the automatic ice making machine 23. In addition, an engagement recess 25 a that engages with the engagement pin 26 b of the door-side system coupling member 26 is provided at the lower front portion of the ice storage container receiver 25.

次に、扉側係合部材26の係合ピン26bと収納容器受け25の係合凹部25aとの関係について、図3と図4を参照して説明する。
図3は補助扉16を開けた直後の係合部材26周辺の断面詳細図で、図4は補助扉16を閉めた時の係合部材26周辺の断面詳細図である。
Next, the relationship between the engagement pin 26b of the door side engagement member 26 and the engagement recess 25a of the storage container receiver 25 will be described with reference to FIGS.
3 is a detailed sectional view around the engaging member 26 immediately after the auxiliary door 16 is opened, and FIG. 4 is a detailed sectional view around the engaging member 26 when the auxiliary door 16 is closed.

28は係合部材の固定具で補助扉16の扉内側材27の凹部27aにネジ等で固定されており、特に上下方向に可変出来るように、図示にはないが、固定具28のネジ締め用穴は長穴になっている。これは、各々の係合部材が、冷蔵庫本体側と扉側と別れている為に出来てしまう製作上のバラツキを許容することを目的としている。   Reference numeral 28 denotes a fixing member for the engaging member, which is fixed to the concave portion 27a of the door inner member 27 of the auxiliary door 16 with a screw or the like. The service hole is a long hole. The purpose of this is to allow manufacturing variations that occur because each engaging member is separated from the refrigerator main body side and the door side.

29は、係合部材26と係合部材固定具28とを係止する回転軸に設けられた弾性部材であり、その一端は、係合部材固定具28の傾斜面に位置させ、もう一端は係合部材26の棒状の後方延設部26aの内側に位置されている。この弾性部材29は、負荷のない状態における角度が90度程度となるように形成されており、係合ピン26bが貯氷容器受25側に付勢されるように備えられている。すなわち、補助扉16の開動作時は、図3に示す通り、貯氷容器24と貯氷容器受け25、及び、貯氷された氷の自重により、係合ピン26bと貯氷容器受け前端係合凹部25aが、丁度、係合されるような角度に設定されている。   Reference numeral 29 denotes an elastic member provided on a rotating shaft that locks the engaging member 26 and the engaging member fixing tool 28, one end of which is positioned on the inclined surface of the engaging member fixing tool 28, and the other end. The engaging member 26 is positioned inside the rod-like rearward extending portion 26a. The elastic member 29 is formed so that the angle in the state without load is about 90 degrees, and is provided so that the engaging pin 26b is urged toward the ice storage container receiver 25 side. That is, during the opening operation of the auxiliary door 16, as shown in FIG. 3, the engaging pin 26b and the ice storage container receiving front end engaging recess 25a are formed by the ice storage container 24, the ice storage container receiver 25, and the dead weight of the ice stored. The angle is set so that it is just engaged.

一方、補助扉16が閉まった時は、係合解除手段を備えることによって係合を解除して主扉14のみを開けるときに貯氷容器24が引き出されることを防ぐことができる。図4に示す通り、主扉の開口下部15aに補助扉16側に向けて延出した突起部15bに、補助扉16側の係合部材26の前端部26cが乗り上げることで、係合ピン26bが下方に移動し、貯氷容器受25の前端係合凹部25aよりも、下側に位置することで、係合ピン26bと貯氷容器受25の前端係合凹部25aとの係合を解除することができる。   On the other hand, when the auxiliary door 16 is closed, it is possible to prevent the ice storage container 24 from being pulled out when the engagement is released and only the main door 14 is opened by providing the engagement release means. As shown in FIG. 4, the front end portion 26c of the engaging member 26 on the auxiliary door 16 side rides on the protruding portion 15b extending toward the auxiliary door 16 side on the opening lower portion 15a of the main door, whereby the engaging pin 26b. Moves downward and is positioned below the front end engaging recess 25a of the ice storage container receiver 25, thereby releasing the engagement between the engagement pin 26b and the front end engaging recess 25a of the ice storage container receiver 25. Can do.

この一連の動作が成り立つことによって、主扉14を開ける時は、貯氷容器受25は通常の位置である製氷室23下部に位置することになり、また、補助扉16を開ける際は、貯氷容器受25と貯氷容器24が補助扉16の回動に伴い、前方に引き出せることが可能になるのである。   As a result of this series of operations, when the main door 14 is opened, the ice storage container receiver 25 is positioned below the ice making chamber 23, which is a normal position, and when the auxiliary door 16 is opened, the ice storage container The receptacle 25 and the ice storage container 24 can be pulled forward as the auxiliary door 16 rotates.

26dは係合部材26の一段低い位置にある段差部である。この段差部26dは特に無くても前述の一連の動作に支障はないが、段差部26dがあることにより、特に補助扉16を閉めた際に発生する、係合ピン26bと貯氷容器受凹部25aとが解除されるA寸法が、より多く確保できることで、前述の固定具28の長穴と同様に、製作上のバラツキを許容することを可能にするものである。   Reference numeral 26 d denotes a stepped portion at a position one step lower than the engaging member 26. Even if the step 26d is not particularly provided, the above-described series of operations is not hindered. However, the presence of the step 26d causes the engagement pin 26b and the ice storage container receiving recess 25a to be generated particularly when the auxiliary door 16 is closed. Since a larger A dimension can be secured, it is possible to allow manufacturing variations as in the case of the long hole of the fixture 28 described above.

次に、補助扉16の開閉時の貯氷容器受25の動作について図5を参照して説明する。
図5に示すように、開扉動作と共に引出された貯氷容器受25と貯氷容器24は、製氷室23外壁に設けた支持部30前端のストッパー30aに係止されることにより、更なる前方への引出しが規制される。その為、この係止された状態が補助扉16の最大開き時となる。補助扉16の最大開き角度は通常90度より大きく、この実施形態では105度に設定されている。
Next, the operation of the ice storage container receiver 25 when the auxiliary door 16 is opened and closed will be described with reference to FIG.
As shown in FIG. 5, the ice storage container receiver 25 and the ice storage container 24 pulled out together with the opening operation are locked forward by a stopper 30 a at the front end of the support portion 30 provided on the outer wall of the ice making chamber 23, thereby moving further forward. Withdrawal is regulated. Therefore, this locked state is when the auxiliary door 16 is fully opened. The maximum opening angle of the auxiliary door 16 is usually larger than 90 degrees, and is set to 105 degrees in this embodiment.

補助扉16を閉めている際は、補助扉16側の係合部材26の係合ピン26bが、貯氷容器受前端の係合凹部25a内を左側にスライドしながら、貯氷容器受25と貯氷容器24を背面側に押し込むことになる。その閉めていく過程で、貯氷容器受25が扉内側材27や主扉側の開口部15に当ってロックせず、スムーズに動作することが前提となるが、ここでは、係合ピン26bと貯氷容器受25の係合凹部25a間に多少の隙間を設けて適度な遊び代(5mm程度)B寸法を設けると共に、貯氷容器受25の前端角部25dの扉側を丸める等の配慮をしている。   When the auxiliary door 16 is closed, the engaging pin 26b of the engaging member 26 on the auxiliary door 16 side slides to the left in the engaging recess 25a at the front end of the ice storage container, and the ice storage container receiver 25 and the ice storage container 24 is pushed to the back side. In the process of closing, it is assumed that the ice storage container receiver 25 does not lock against the door inner member 27 or the opening 15 on the main door side, and operates smoothly. Provide some allowance (about 5mm) B dimension by providing a slight gap between the engagement recesses 25a of the ice storage container receiver 25, and take care such as rounding the door side of the front end corner 25d of the ice storage container receiver 25. ing.

更に、貯氷容器受25には、自身の走行がスムーズとなるように滑車を設けるとともに、主扉側の開口部15にも、貯氷容器受25の走行を補助するための滑車15cを設け、更に、この滑車15cと貯氷容器受25間に適度な隙間(5mm程度)C寸法を確保している。   Furthermore, the ice storage container receiver 25 is provided with a pulley so that the running of the ice storage container receiver 25 is smooth, and the opening 15 on the main door side is provided with a pulley 15c for assisting the traveling of the ice storage container receiver 25. An appropriate gap (about 5 mm) C is secured between the pulley 15c and the ice storage container receiver 25.

25bは、貯氷容器受25に設けた案内リブであり、貯氷容器24の前後方向の案内を目的としている。また、25cは、貯氷容器受25に設けたストッパーであり、補助扉16の開動作で一度引き出された貯氷容器24を、更に、前方に引出す際の貯氷容器24の脱落防止を目的としている。この様な配慮をすることにより、通常取り出し難い貯氷容器24の奥側の氷も、補助扉16の開閉だけで、安全で、かつ、容易に取り出すことが出来るのである。   Reference numeral 25b denotes a guide rib provided on the ice storage container receiver 25 for the purpose of guiding the ice storage container 24 in the front-rear direction. Reference numeral 25c denotes a stopper provided in the ice storage container receiver 25 for the purpose of preventing the ice storage container 24 from dropping out when the ice storage container 24 once pulled out by the opening operation of the auxiliary door 16 is further pulled out forward. By taking such consideration into consideration, the ice on the back side of the ice storage container 24 that is usually difficult to remove can be safely and easily removed simply by opening and closing the auxiliary door 16.

次に、図6について説明する。図6は補助扉側のガスケット周辺の詳細図である。この発明は特に冷凍室に係るものである。即ち、主扉開口部15と補助扉16間のシールは、冷蔵庫内の冷気漏れを防止するとともに、冷蔵庫外の熱が庫内側に伝達されることを抑制する上で、とても重要な役目を担う。   Next, FIG. 6 will be described. FIG. 6 is a detailed view around the gasket on the auxiliary door side. The present invention particularly relates to a freezer compartment. That is, the seal between the main door opening 15 and the auxiliary door 16 plays a very important role in preventing cold air leakage in the refrigerator and suppressing the heat outside the refrigerator from being transmitted to the inside of the refrigerator. .

本例では図6に示すように、主扉14にも適用している磁石付ガスケット31で主扉開口部15と補助扉16間のシールを行うが、主扉開口部15の形状が複雑であることから、材質は樹脂性から形成される為、磁石の吸着力がない。そこで、磁石部31aと当接する面には磁性部材が必要となる。しかし、磁石付ガスケット31と当接する面に、直接、磁性部材を設けるとなると、部材の固定方法や、表面処理などの理由により、高価な構造となってしまう。そこで、今回は、主扉開口部15の断熱材側全周に凹部15aを設け、磁石付ガスケット31と当接する板厚を0.5〜1.0mm程度の薄肉にして、この凹部15aに磁性部材32をアルミテープ等で固定することで、安価で、かつ、確実に冷気をシールできるのである。   In this example, as shown in FIG. 6, the gasket 31 with a magnet applied to the main door 14 is sealed between the main door opening 15 and the auxiliary door 16, but the shape of the main door opening 15 is complicated. For this reason, since the material is made of resin, there is no magnetic attraction. Therefore, a magnetic member is required on the surface that comes into contact with the magnet portion 31a. However, if a magnetic member is provided directly on the surface that comes into contact with the gasket 31 with magnet, the structure becomes expensive due to the fixing method of the member, surface treatment, and the like. Therefore, this time, a recess 15a is provided on the entire periphery of the main door opening 15 on the heat insulating material side, and the thickness of the plate abutting on the gasket 31 with magnet is reduced to about 0.5 to 1.0 mm. By fixing the member 32 with aluminum tape or the like, cold air can be reliably sealed at a low cost.

次に、図7について説明する。図7は、補助扉回転軸側の周辺詳細図である。   Next, FIG. 7 will be described. FIG. 7 is a detailed view of the periphery on the auxiliary door rotating shaft side.

13は主扉14用の支持部であり、33は主扉14用のクローザーである。36 は補助扉16側の支持部下面側にネジ35等で固定された補助扉16側のクローザーであり、34aは主扉エンドピース34のクローザー33の手前側に近接して設けられた凹部で、この凹部34aに補助扉16側の支持部18を固着している。この補助扉16側のクローザー36は、ユーザーの通常の使用状態では不要なものであるが、ユーザーの故意的な扉開閉や他扉を閉めた際に生ずる風圧により、補助扉16が半開き状態になることを抑制することを目的としている。   Reference numeral 13 denotes a support portion for the main door 14, and 33 denotes a closer for the main door 14. Reference numeral 36 denotes a closer on the auxiliary door 16 side which is fixed to the lower surface side of the supporting portion on the auxiliary door 16 side with a screw 35 or the like, and 34a denotes a concave portion provided in the vicinity of the front side of the closer 33 of the main door end piece 34. The support 18 on the auxiliary door 16 side is fixed to the recess 34a. The closer 36 on the side of the auxiliary door 16 is not necessary in the normal use state of the user, but the auxiliary door 16 is in a half-opened state due to the wind pressure generated when the user intentionally opens and closes the door or closes the other door. The purpose is to suppress becoming.

次に図8について説明する。
図8は主扉の支持部側と補助扉の支持部側との関係を示す図である。正面から見て、補助扉の支持部側が主扉の支持部側と同じ側にある時は補助扉を開ける時に補助扉の把手が主扉の支持部側より略補助扉の巾分離れたところに位置するため主扉の支持部を起点とする回転モーメントが大きくなり、主扉の磁石等による吸着力が弱いと補助扉を開く力で補助扉が開く前に主扉が開くことがあった。
Next, FIG. 8 will be described.
FIG. 8 is a diagram showing the relationship between the support portion side of the main door and the support portion side of the auxiliary door. When the support part side of the auxiliary door is on the same side as the support part side of the main door when viewed from the front, when the auxiliary door is opened, the handle of the auxiliary door is separated from the support part side of the main door by about the width of the auxiliary door. Rotation moment starting from the support part of the main door increases, and the main door may open before the auxiliary door opens due to the force to open the auxiliary door if the adsorption force by the magnet of the main door is weak. .

そこで本発明は主扉14の中に補助扉16を設ける時は主扉の支持部30が右側の時は補助扉16の支持部18が補助扉の左側に設けるようにすると補助扉16の把手部19が右側に来て、主扉の支持部30に略補助扉の巾分近づくので、補助扉16を開けようとする時の力による主扉の支持部を起点とする回転モーメントは小さくなり、主扉に働く力は小さくなり主扉は開きにくくなるので、補助扉を開く時に、主扉を押さえていたり、又は開きかけた扉を閉めるなどの手間が不要となり、ユーザーの使い勝手がよくなる。   Therefore, according to the present invention, when the auxiliary door 16 is provided in the main door 14, the support 18 of the auxiliary door 16 is provided on the left side of the auxiliary door 16 when the support portion 30 of the main door is on the right side. Since the portion 19 comes to the right side and approaches the main door support portion 30 by the width of the auxiliary door, the rotational moment starting from the main door support portion due to the force when opening the auxiliary door 16 is reduced. Since the force acting on the main door is reduced and the main door is difficult to open, there is no need to hold down the main door or close the opened door when opening the auxiliary door, which improves the usability of the user.

以上、本実施例の冷蔵庫によれば、回転式扉で開閉される冷凍室でありながら、その内部の収納容器を、補助扉の開扉動作に伴って引き出すことが出来るので、開扉後に更に収納容器を引き出すといった余分な動作が不要となると共に、補助扉の配置を主扉の回転軸側に近接させ、更に主扉の最下部に位置させているので、主扉の回転軸側に収納されている収納物も容易に取り出せて、しかも、適切な高さで収納物を取り出すことができる。   As described above, according to the refrigerator of the present embodiment, although the freezer is opened and closed by the rotary door, the storage container inside thereof can be pulled out with the opening operation of the auxiliary door. The extra operation of pulling out the storage container is not necessary, and the auxiliary door is placed close to the main door's rotary shaft side and positioned at the bottom of the main door, so it can be stored on the main door's rotary shaft side. The stored items can be easily taken out, and the stored items can be taken out at an appropriate height.

また、補助扉の開動作で引き出された収納容器を、更に前方に引き出せることにより、通常、取りだし難い奥側にある収納物も容易に取り出すことができるので使い勝手が良くなる。   In addition, since the storage container pulled out by the opening operation of the auxiliary door can be pulled out further forward, it is possible to easily take out the stored items on the far side which is usually difficult to take out.

また、主扉の一部に設けられた補助扉開口部と補助扉とが磁石付ガスケットで当接しているため、確実に冷蔵庫内の冷気漏れを防止すると共に、冷蔵庫外の熱が庫内側に伝達されることが抑制される。   In addition, since the auxiliary door opening provided in a part of the main door and the auxiliary door are in contact with the gasket with magnet, it is possible to prevent leakage of cold air in the refrigerator and heat outside the refrigerator to the inside of the refrigerator. Transmission is suppressed.

また、補助扉の回転軸側下面にクローザーを備えているので、主扉を故意に開閉させた時や、他扉を閉めた時の負圧により、補助扉が半開き状態になることを抑制することができる。   In addition, since the closer is provided on the lower surface of the rotating shaft of the auxiliary door, the auxiliary door is prevented from being half-opened due to negative pressure when the main door is intentionally opened or closed or when other doors are closed. be able to.

更に、主扉の中に補助扉を設ける時に、補助扉の支持部を主扉の支持部の反対側にすることで、補助扉を開く時の主扉に発生する回転モーメントが小さくなり、主扉が開きにくくすることができる。   Furthermore, when the auxiliary door is provided in the main door, the rotational moment generated in the main door when the auxiliary door is opened is reduced by setting the auxiliary door support to the opposite side of the main door support. The door can be made difficult to open.
