Description

本発明は高断熱性の回転仕切体を設置した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 having a double door with a highly heat insulating rotating partition.

一般に冷蔵庫は、扉によって開閉自在な冷蔵室、冷凍室、野菜室等を備えており、そのそれぞれの室は扉によって開閉自在となっているが、大型の冷蔵庫にあっては前記扉のうち冷蔵室の扉は観音開き式の扉となっている。そして、この観音開き式扉にはその左右いずれか一方に扉に扉開閉に連動して回動する回転仕切体を設け、扉閉止時に生じる扉端面同士間の隙間を塞いで気密を確保するようになっている。 Generally, a refrigerator is provided with a refrigeration room, a freezer room, a vegetable room, etc. that can be opened and closed by a door, and each room can be opened and closed by a door. The door of the room is a double door. And this double door is provided with a rotating partition that rotates in conjunction with the opening and closing of the door on either the left or right side of the door, so as to close the gap between the door end faces when the door is closed to ensure airtightness. It has become.

ここで、上記回転仕切体は扉同士の間の隙間を介して直接外気と接しており、外気から冷蔵室への熱侵入経路ともなるので、断熱性を持つ構成としてある（例えば、特許文献１参照）。 Here, the rotating partition is in direct contact with the outside air through a gap between the doors, and also serves as a heat intrusion path from the outside air to the refrigerator compartment. reference).

図１２は上記特許文献１に記載された回転仕切体を示し、この回転仕切体１００は貯蔵室側外郭部材となる仕切板１０１と外気側外郭部材となる仕切枠体１０２との間に発泡スチロールからなる断熱材１０３を設けて構成してある。 FIG. 12 shows the rotating partition described in Patent Document 1 described above, and this rotating partition 100 is made of foamed polystyrene between a partition plate 101 serving as a storage chamber side shell member and a partition frame 102 serving as an outside air side shell member. A heat insulating material 103 is provided.

また、回転仕切体の断熱性を向上するために、回転仕切体内部に発泡スチロールからなる断熱材１０３に代わり、発泡断熱材を充填させるものもある（例えば、特許文献２、３参照） Moreover, in order to improve the heat insulation of a rotary partition, there is also a type in which a foam heat insulating material is filled in the rotary partition instead of the heat insulating material 103 made of foamed polystyrene (see, for example, Patent Documents 2 and 3).

特開２０１５−１２９６０５号公報JP2015-129605A 特開２０１１−１１２２９０号公報JP 2011-112290 A 特開２０１１−１７４６２５号公報JP 2011-174625 A

貯蔵室側外郭部材４７に形成された注入孔５２は、図９に示すように、貯蔵室側外郭部材４７の平面部から内部空間側に凹んだ段差部７３を備え、その段差部７３から内側にフランジ部７４を形成している。 As shown in FIG. 9, the injection hole 52 formed in the storage chamber side outer member 47 includes a stepped portion 73 that is recessed from the flat portion of the storage chamber side outer member 47 to the inner space side, and the inner side from the stepped portion 73.

It is pasted.

以上のように構成した冷蔵庫について、次にその作用効果について説明する。 Next, the effect of the refrigerator configured as described above will be described.

冷凍サイクルを構成する圧縮機２３で冷媒が圧縮され、コンデンサで放熱し、キャピラリーチューブで減圧され、冷却器２０で生成された冷気は、冷却ファン２１からダクトを介して冷蔵庫本体１内の冷蔵室１４、切替室１５、製氷室１６、野菜室１７、冷凍室１８に供給され、所定の温度に冷却される。 The refrigerant is compressed by the compressor 23 constituting the refrigeration cycle, radiated by the condenser, depressurized by the capillary tube, and the cold air generated by the cooler 20 is supplied from the cooling fan 21 through the duct into the refrigerator compartment in the refrigerator main body 1. 14, the switching chamber 15, the ice making chamber 16, the vegetable chamber 17, and the freezing chamber 18 are cooled to a predetermined temperature.

冷蔵室１４の扉は、第一扉７１と第二扉７２からなる観音開き式扉７となっていて、それぞれ冷蔵庫本体１に扉ヒンジ１３で回動自在に軸支している。 The door of the refrigerator compartment 14 is a double door type door 7 including a first door 71 and a second door 72, and is pivotally supported by the refrigerator main body 1 by a door hinge 13.

冷蔵庫の観音開き式扉７の第一扉７１に軸支した回転仕切体３５は、貯蔵室側外郭部材４７と外気側外郭部材４８との間に介在部材である軟質袋部材６４を介して回転仕切体用発泡断熱材５０を充填して構成しているので、従来の発泡スチロールを断熱材としているものに比べその断熱性は格段に高いものとなる。よって、回転仕切体３５を介して冷蔵室１４内に侵入しようとする外気熱を強力かつ効果的に抑制することができる。 The rotary partition 35 pivotally supported on the first door 71 of the double door 7 of the refrigerator is a rotary partition via a soft bag member 64 which is an interposed member between the storage chamber side outer member 47 and the outside air side outer member 48. Since it is configured by filling the body foam heat insulating material 50, its heat insulating property is remarkably higher than that of a conventional foamed polystyrene as a heat insulating material. Therefore, it is possible to strongly and effectively suppress the outside air heat that tends to enter the refrigerator compartment 14 via the rotating partition 35.

また、回転仕切体３５は上下に細長く回転仕切体用発泡断熱材５０を充填した際、従来の構成では、その発泡圧によって貯蔵室側外郭部材４７と外気側外郭部材４８とが嵌合している部分から回転仕切体用発泡断熱材５０が漏出しやすい課題を有しているが、本実施の形態では、回転仕切体３５は貯蔵室側外郭部材４７と外気側外郭部材４８との間に介在部材である軟質袋部材６４を介して回転仕切体用発泡断熱材５０を充填して構成しているので、貯蔵室側外郭部材４７と外気側外郭部材４８とが嵌合している部分からの回転仕切体用発泡断熱材５０の漏れを確実に抑制することができ、断熱性を高めた回転仕切体３５を得ることができる。 In addition, when the rotary partition 35 is elongated vertically and filled with the foamed heat insulating material 50 for the rotary partition, in the conventional configuration, the storage chamber side outer member 47 and the outside air side outer member 48 are fitted by the foaming pressure. However, in this embodiment, the rotary partition 35 is interposed between the storage chamber side outer member 47 and the outside air side outer member 48. Since the foamed heat insulating material 50 for the rotating partition is filled through the soft bag member 64 which is an interposition member, the storage chamber side outer member 47 and the outside air side outer member 48 are fitted from the portion where they are fitted. Leakage of the foaming heat insulating material 50 for the rotating partition can be reliably suppressed, and the rotating partition 35 with improved heat insulation can be obtained.

さらに、貯蔵室側外郭部材４７と外気側外郭部材４８との間に備えた介在部材である軟質袋部材６４により、回転仕切体用発泡断熱材５０と、回転仕切体３５を構成する貯蔵室側外郭部材４７と外気側外郭部材４８との接着強度を緩和し、回転仕切体３５の冷熱温度差によるソリや変形を抑制することができる。 Further, the flexible bag member 64 which is an interposed member provided between the storage chamber side outer member 47 and the outside air side outer member 48 is provided with the foaming heat insulating material 50 for the rotating partition and the storage chamber side constituting the rotating partition 35. The adhesion strength between the outer shell member 47 and the outer air side outer member 48 can be relaxed, and warping and deformation due to the temperature difference of the rotating partition 35 can be suppressed.

また、貯蔵室側外郭部材４７の注入孔５２と回転仕切体補強板５５の孔６６の間にはリング状のシールフォーム６９、および、空気抜き孔５３と孔５７との間には矩形状のシールフォーム７０を有して、貯蔵室側外郭部材４７と回転仕切体補強板５５とは爪５６によって固定されるので、軟質袋部材６４を介して、より確実に回転仕切体３５内部へ回転仕切体用発泡断熱材５０の充填性を高めることができる。 Further, a ring-shaped seal foam 69 is formed between the injection hole 52 of the storage chamber side outer member 47 and the hole 66 of the rotating partition reinforcing plate 55, and a rectangular seal is formed between the air vent hole 53 and the hole 57. Since the storage chamber side outer member 47 and the rotating partition reinforcing plate 55 are fixed by the claw 56 with the foam 70, the rotating partition body is more reliably brought into the rotating partition 35 through the soft bag member 64. The filling property of the foamed heat insulating material 50 can be enhanced.

また、回転仕切体３５の外郭を構成する貯蔵室側外郭部材４７と外気側外郭部材４８との空間に介在する軟質袋部材６４は、貯蔵室側外郭部材４７の注入孔５２と回転仕切体補
強板５５の孔６６に対向して開口孔６５が設けられ、回転仕切体補強板５５の孔６６と軟質袋部材６４の開口孔６５の間には両面接着剤６７を介して軟質袋部材６４が回転仕切体補強板５５に固定されるので、軟質袋部材６４を介して、より確実に回転仕切体３５内部へ回転仕切体用発泡断熱材５０の充填性を高めることができる。 In addition, the soft bag member 64 interposed in the space between the storage chamber side outer member 47 and the outside air side outer member 48 constituting the outer shell of the rotating partition 35 is provided to reinforce the injection hole 52 of the storage chamber side outer member 47 and the rotary partition member. An opening hole 65 is provided to face the hole 66 of the plate 55, and the soft bag member 64 is interposed between the hole 66 of the rotating partition reinforcing plate 55 and the opening hole 65 of the soft bag member 64 through a double-sided adhesive 67. Since it is fixed to the rotating partition reinforcing plate 55, the filling property of the foaming heat insulating material 50 for the rotating partition can be more reliably increased into the rotating partition 35 via the soft bag member 64.

また、上記回転仕切体３５はその上下部分をヒンジ部材４６で第一扉７１に枢結するとともに、ヒンジ部材４６の設置部分には発泡スチロールからなる成形断熱部材４９を設けてあるので、複雑な構造となるヒンジ部材４６の軸支部や結露防止用ヒータ５９のハーネス接続部などの近傍を成形断熱部材４９で構成することで、貯蔵室側外郭部材４７と外気側外郭部材４８との空間を簡素な構造にでき、軟質袋部材６４を簡素な矩形形状としたものとすることができ、ヒンジ部材４６近傍の回転仕切体用発泡断熱材５０の漏れや、充填不足を解消することができる。これにより、回転仕切体３５の回転動作を安定したものとすることができる。 The rotary partition 35 is pivotally connected to the first door 71 by the hinge member 46 at the upper and lower portions, and a molded heat insulating member 49 made of foamed polystyrene is provided at the installation portion of the hinge member 46, so that the complicated structure is provided. By forming the vicinity of the shaft support portion of the hinge member 46 and the harness connection portion of the dew condensation prevention heater 59 with the molded heat insulating member 49, the space between the storage chamber side outer member 47 and the outside air side outer member 48 can be simplified. The structure can be made, and the flexible bag member 64 can be made into a simple rectangular shape, and leakage of the foaming heat insulating material 50 for the rotating partition near the hinge member 46 and insufficient filling can be solved. Thereby, the rotation operation of the rotary partition 35 can be stabilized.

また、筒状部材６０は内部にヒンジ部材４６の軸支部を介して回転仕切体３５内に引き込んだ結露防止用ヒータ５９を通しているので、筒状部材６０内ではその伸縮等の動きを自由に行うことができ、回転仕切体用発泡断熱材５０を充填していても結露防止用ヒータ５９のねじれ等による断線を引き起こすようなことを防止できる。 Further, since the tubular member 60 passes through a condensation prevention heater 59 drawn into the rotary partition 35 through the shaft support portion of the hinge member 46, the tubular member 60 freely moves such as expansion and contraction. Even if the foamed heat insulating material 50 for the rotating partition is filled, it is possible to prevent disconnection due to twisting of the heater 59 for preventing condensation.

さらに、回転仕切体３５は回転仕切体用発泡断熱材５０を充填した区域では外気側外郭部材４８の内面に回転仕切体マグネット５８を貼り付けて表面をテープ６１で覆っているので、介在部材である軟質袋部材６４に加えて、回転仕切体用発泡断熱材５０が外気側外郭部材４８と回転仕切体マグネット５８との間に入り込むのを確実に防止でき、発泡断熱材の入り込みによる磁力低下を防止できる。その結果、回転仕切体３５による冷蔵室１４の密閉を確実かつ良好なものとすることができ、外気熱の侵入をより効果的に抑制して省エネ性を高めることができる。 Further, in the area where the rotary partition 35 is filled with the foam heat insulating material 50 for the rotary partition, the rotary partition magnet 58 is attached to the inner surface of the outside air side outer member 48 and the surface is covered with the tape 61. In addition to a certain soft bag member 64, it is possible to reliably prevent the foaming heat insulating material 50 for the rotating partition from entering between the outside air side outer member 48 and the rotating partition magnet 58, and to reduce the magnetic force due to the entry of the foam insulating material. Can be prevented. As a result, the refrigerating chamber 14 can be reliably sealed by the rotating partition 35, and the intrusion of outside air heat can be more effectively suppressed to improve the energy saving performance.

また、回転仕切体３５は貯蔵室側外郭部材４７の内面に金属製の回転仕切体補強板５５を設けた構成としてあるから、回転仕切体用発泡断熱材５０の熱収縮によって生じる変形を防止でき、扉閉止時における密閉性をより高いものとして省エネ性を更に向上させることができる。 Further, since the rotary partition 35 has a configuration in which a metal rotary partition reinforcing plate 55 is provided on the inner surface of the storage chamber side outer member 47, deformation caused by thermal contraction of the foam heat insulating material 50 for the rotary partition can be prevented. The energy-saving property can be further improved by making the sealing property at the time of closing the door higher.

また、回転仕切体３５内の回転仕切体用発泡断熱材５０は軟質袋部材６４を介して回転仕切体補強板５５に接しているので、回転仕切体用発泡断熱材５０と回転仕切体補強板５５とは間接的な接触となり、回転仕切体用発泡断熱材５０の熱収縮によって生じる回転仕切体補強板５５の直接的な変形を抑制できる。 Moreover, since the foaming heat insulating material 50 for rotating partitions in the rotating partition 35 is in contact with the rotating partition reinforcing plate 55 via the soft bag member 64, the foam insulating material 50 for rotating partitions and the rotating partition reinforcing plate are used. It becomes an indirect contact with 55 and can suppress the direct deformation | transformation of the rotary partition reinforcement board 55 which arises by the thermal contraction of the foaming heat insulating material 50 for rotary partitions.

また、回転仕切体補強板５５は貯蔵室側外郭部材４７に設けた回転仕切体用発泡断熱材の注入孔５２と空気抜き孔５３に対向する孔を含めその長手方向に複数の孔５７を形成してあるから、貯蔵室側外郭部材４７に設けた注入孔５２から軟質袋部材６４内に充填する回転仕切体用発泡断熱材５０の注入を可能としつつ回転仕切体補強板５５の軽量化を図ることができる。その結果、回転仕切体３５自体も軽量化でき、回転仕切体３５の回転動作が安定するとともに、回転時に生じる回転仕切体３５の慣性力が軽減するので衝突音等もより少ないものになる。 The rotating partition reinforcing plate 55 includes a plurality of holes 57 in the longitudinal direction including a hole facing the foaming heat insulating material for the rotating partition provided in the storage chamber side outer member 47 and a hole facing the air vent hole 53. Therefore, the rotating partition reinforcing plate 55 can be reduced in weight while allowing the foam insulating material 50 for the rotating partition to be filled into the soft bag member 64 from the injection hole 52 provided in the outer shell member 47 of the storage chamber. be able to. As a result, the rotating partition 35 itself can be reduced in weight, the rotating operation of the rotating partition 35 can be stabilized, and the inertial force of the rotating partition 35 generated during the rotation can be reduced, so that the collision sound and the like can be reduced.

また、上記回転仕切体３５は方形状としてあるので、その左右全域に渡って良好な断熱効果を発揮するようになり、断熱効果を高めることができる。 Moreover, since the said rotation partition 35 is made into square shape, it comes to exhibit a favorable heat insulation effect over the right-and-left whole region, and can improve a heat insulation effect.

また、回転仕切体３５は貯蔵室側外郭部材４７の貯蔵室側面に緩衝シート５４を装着してあるので、回転仕切体３５が第一扉７１の内面側に回転して第一扉内枠３１ａの縦壁面
に衝突してもその衝突音や振動を抑制することができる。したがって、第一扉７１の開成に連動して回転仕切体３５が回転しても衝突音や振動を感じにくい使い勝手を高めた冷蔵庫を提供することができる。 In addition, since the rotating partition 35 has the buffer sheet 54 attached to the storage chamber side surface of the storage chamber side outer member 47, the rotating partition 35 rotates to the inner surface side of the first door 71 and the first door inner frame 31a. Even if it collides with the vertical wall surface, the collision sound and vibration can be suppressed. Therefore, it is possible to provide a refrigerator with improved usability that makes it difficult to feel a collision sound or vibration even when the rotary partition 35 rotates in conjunction with the opening of the first door 71.

また、緩衝シート５４は貯蔵室側外郭部材４７の貯蔵室側面の長手方向に亘って設けてあるので、この注入孔５２や空気抜き孔５３を覆い隠し、貯蔵室側外郭部材４７の貯蔵室側面をすっきりとしたものにすることができる。 Further, since the buffer sheet 54 is provided along the longitudinal direction of the storage chamber side surface of the storage chamber side outer member 47, the buffer sheet 54 covers and conceals the injection hole 52 and the air vent hole 53, and the storage chamber side surface of the storage chamber side outer member 47 is covered. It can be neat.

また、図１１（ａ）（ｂ）に示すように回転仕切体３５の回転遊端側と第二扉７２の内面縦壁との間に柔軟な補助シール部材６３を設けておくことによって、回転仕切体３５の回転軌跡によって生じる隙間Ｔを前記補助シール部材６３によって閉塞することができる。これにより、回転仕切体遊端と扉縦壁内面との間の隙間から外気が侵入するのをより確実に防止することができ、更に省エネ性を高めることができる。 Further, as shown in FIGS. 11A and 11B, a flexible auxiliary seal member 63 is provided between the rotary free end side of the rotary partition 35 and the inner wall vertical wall of the second door 72, thereby rotating the rotary partition 35. A gap T generated by the rotation trajectory of the partition 35 can be closed by the auxiliary seal member 63. Thereby, it can prevent more reliably that external air penetrate | invades from the clearance gap between a rotating partition free end and a door vertical wall inner surface, and can improve energy-saving property further.

なお、本実施の形態では、回転仕切体３５の外郭を構成する貯蔵室側外郭部材４７と外気側外郭部材４８との間に介在する介在部材を軟質袋部材６４で説明したが、介在部材はこれに限定されるものではなく、例えば、ブロー成形部材や離型材塗布、離型テープ等の貼付でも可能である。 In the present embodiment, the interposition member interposed between the storage chamber side outer member 47 and the outer air side outer member 48 constituting the outer shell of the rotary partition 35 has been described as the soft bag member 64. However, the present invention is not limited to this. For example, it is possible to apply a blow molded member, a release material application, a release tape or the like.

また、本実施の形態では、回転仕切体内部にマグネット５８を埋設したもので説明したが、これは、貯蔵室側外郭部材４７および外気側外郭部材４８を熱伝導性の低い樹脂で形成することを前提とした為である。すなわち、扉側のマグネットを備えたガスケットが回転仕切体に確実に吸着し、シール性を確保するために回転仕切体内部にマグネット５８を埋設したものであるが、これに限定されることなく、回転仕切体内部にマグネット５８を用いずに着磁性のある鉄板を貯蔵室側外郭部材としたものでもよい。 In the present embodiment, the magnet 58 is embedded in the rotary partition. However, this is because the storage chamber side outer member 47 and the outdoor air side outer member 48 are formed of a resin having low thermal conductivity. This is because of the assumption. That is, the gasket provided with the door-side magnet is securely adsorbed to the rotating partition, and the magnet 58 is embedded inside the rotating partition to ensure sealing performance, but not limited thereto, A magnetized iron plate may be used as the storage chamber side outer member without using the magnet 58 inside the rotating partition.

この場合、回転仕切体内部のマグネット配置空間部分を軟質袋部材６４を介して回転仕切体用発泡断熱材５０で充填することができ、断熱性の向上と回転仕切体３５の強度を高めることができる。この場合、貯蔵室側外郭部材に鉄板を用いることで貯蔵室側外郭部材４７に設けた回転仕切体補強板５５も不要、あるいは薄肉化することができ、断熱性と強度とコストの最適バランスを図ることができる。 In this case, the magnet arrangement space portion inside the rotary partition can be filled with the foamed heat insulating material 50 for the rotary partition via the soft bag member 64, so that the heat insulation can be improved and the strength of the rotary partition 35 can be increased. it can. In this case, by using an iron plate for the storage chamber side outer member, the rotating partition reinforcing plate 55 provided in the storage chamber side outer member 47 can be eliminated or thinned, and the optimum balance of heat insulation, strength and cost can be achieved. Can be planned.

また、本実施の形態では、回転仕切体３５の上端部のヒンジ部材近傍には発泡スチロールからなる成形断熱部材４９を設けたもので説明したが、これに限定されるものではなく、回転仕切体３５の上下端部のヒンジ部材近傍も含めて回転仕切体３５内部のほぼ全域に軟質袋部材６４を介して回転仕切体用発泡断熱材５０を充填する仕様としてもよい。 Further, in the present embodiment, the description has been made on the case where the molded heat insulating member 49 made of foamed polystyrene is provided in the vicinity of the hinge member at the upper end of the rotating partition 35, but the present invention is not limited to this, and the rotating partition 35 is not limited thereto. It is good also as a specification which fills the foaming heat insulating material 50 for rotary partitions through the soft bag member 64 to the substantially whole area inside the rotary partition 35 also including the hinge member vicinity of upper and lower ends.

この場合、発泡ウレタンの充填率向上による断熱性能向上、強度向上、発泡スチロールからなる成形断熱部材４９の不要によるコストダウン等の効果を得ることができる。 In this case, it is possible to obtain effects such as an improvement in heat insulation performance due to an improvement in the filling ratio of urethane foam, an improvement in strength, and a cost reduction due to the need for the molded heat insulation member 49 made of foamed polystyrene.

以上、本発明に係る冷蔵庫について、上記実施の形態を用いて説明したが、本発明は、これに限定されるものではない。すなわち、今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。つまり、本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。 As mentioned above, although the refrigerator concerning this invention was demonstrated using the said embodiment, this invention is not limited to this. That is, the embodiment disclosed this time should be considered as illustrative in all points and not restrictive. That is, the scope of the present invention is shown not by the above description but by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
