Description

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

最近の食生活においては、健康と食材の安全性確保の観点から、家庭で食品を冷凍保存するホームフリージングすることが頻繁に行なわれるようになってきた。従って、冷蔵庫にも手軽にホームフリージングをできる急速冷凍室を追加する要求が高くなってきた。ホームフリージングでは、急速冷凍室内で食品を急速冷凍することで、−５℃〜−１℃の温度帯をすばやく通過させる。この温度帯では氷結晶が生成するため、氷結晶が食品の細胞を傷つけて食品解凍時に食品のうまみが逃げるのを防ぐ必要があるからである。そのために急速冷凍室は、天井面に大風量の冷気を噴出するための冷気ダクトを設け、また急速冷凍容器の底面には金属板を設け、食品を急速冷凍することができるような構造になっている。（例えば、特許文献１参照。） In recent eating habits, from the viewpoint of ensuring health and food safety, home freezing in which food is stored frozen at home has been frequently performed. Therefore, a demand for adding a quick freezer room that can easily perform home freezing in the refrigerator has been increased. In home freezing, foods are rapidly frozen in a quick freezing room to quickly pass through a temperature range of -5 ° C to -1 ° C. This is because ice crystals are formed in this temperature range, and it is necessary for ice crystals to damage the food cells and prevent the food from escaping when the food is thawed. For this purpose, the quick freezer compartment has a structure in which a cold air duct for ejecting a large amount of cool air is provided on the ceiling surface, and a metal plate is provided on the bottom surface of the quick freeze container so that food can be quickly frozen. ing. (For example, refer to Patent Document 1.)

特開平１０−３８４５６号公報（３頁、図１）Japanese Patent Laid-Open No. 10-38456 (page 3, FIG. 1)

しかし、従来の急速冷凍室は、急速冷凍容器の収納深さ寸法についてはあまり考慮されてなかった。容器の収納深さ寸法が小さい場合には、大きな食品が入らなくなり、容器の収納深さ寸法が大きい場合には、急速冷凍室の占める容積が大きくなるうえ、冷気を吐出する冷気ダクトから食品までの距離が大きくなり、冷凍速度が遅くなってしまう。 However, in the conventional quick freezer, the storage depth dimension of the quick freeze container has not been considered much. If the container storage depth is small, large foods will not enter. If the container storage depth is large, the quick freezer will occupy a large volume, and from the cold air duct that discharges cold air to the food. Will increase the distance, and the refrigeration rate will slow down.

また、冷凍室に貯蔵する食品を既に貯蔵してある食品の上に新しい食品を重ねて貯蔵すると、既に貯蔵してある食品の食品温度が新しい食品のために温度上昇し、新鮮度低下につながる可能性がある。このときに、急速冷凍を行った食品の温度が−５℃を上回ってしまうと、再冷凍時に氷結晶が生成し食品細胞を傷つけ、食品のうまみが逃げ、急速冷凍の効果が薄れてしまう。 In addition, if the food stored in the freezer is stored on top of the food that has already been stored, the food temperature of the food that has already been stored rises due to the new food, leading to a decrease in freshness. there is a possibility. At this time, if the temperature of the rapidly frozen food exceeds −5 ° C., ice crystals are generated at the time of refreezing, and the food cells are damaged, and the taste of the food escapes and the effect of the quick freezing is diminished.

従って、貯蔵食品を積み重ねない冷蔵庫の要求が高くなっている。発明者らの調査によると、一般家庭用冷蔵庫に貯蔵される収納高さ寸法別冷凍食品例は、表１に示す如く、その収納高さ寸法が100mm以下の食品が多いにも拘らず、従来例の冷蔵庫では、収納深さ寸法が120mm以上の収納ケースしか無いため、実際の家庭用冷蔵庫では、貯蔵食品の積み重ねが多くみられた。食品を収納する容器の段数を増やすことにより、冷凍室中の食品を積み重ねを少なくすることはできるが、必要とする冷凍室の高さ寸法を増やしてしまったり、一段の収納深さ寸法が小さくなり大きな食品を貯蔵できなくなってしまう恐れがある。 Therefore, the demand for refrigerators that do not stack stored food is increasing. According to the inventors' investigation, examples of frozen foods stored in general household refrigerators according to storage height dimensions are as shown in Table 1, although there are many foods whose storage height dimensions are 100 mm or less. In the example refrigerator, there is only a storage case with a storage depth of 120 mm or more, so in an actual household refrigerator, a large amount of stored food was observed. By increasing the number of containers for storing food, it is possible to reduce the stacking of food in the freezer, but the required height of the freezer can be increased, or the storage depth of one step can be reduced. There is a risk that large foods cannot be stored.

本発明は、以上のような課題を解決するためになされたもので、ホームフリージングができる急速冷凍室を有する冷蔵庫において、素早く急速冷凍を行い、また、急速冷凍を行った食品を新鮮な状態で保存できる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 order to solve the above-described problems, and in a refrigerator having a quick freezing room capable of home freezing, quick freezing is performed quickly, and food that has undergone quick freezing is in a fresh state.

次に、図２により各貯蔵室３０、４０、６０、７０、８０の具体的構成の一実施例を説明する。 Next, an embodiment of a specific configuration of each storage room 30, 40, 60, 70, 80 will be described with reference to FIG.

図２は、図１のＡ−Ａ線縦断面図である。冷蔵庫の断熱箱体２は、外箱３と内箱４と、外箱３と内箱４との間に充填された断熱材５とにより構成されている。断熱箱体２は、その上部に冷蔵温度室２０を、その下部に冷凍温度室５０を、断熱材５を内蔵する断熱仕切壁８により区画形成している。 2 is a longitudinal sectional view taken along line AA in FIG. The heat insulating box 2 of the refrigerator includes an outer box 3, an inner box 4, and a heat insulating material 5 filled between the outer box 3 and the inner box 4.

The vegetable container 42 has a rear storage part 42a at the rear part and a front storage part 42b having a storage depth dimension f2 larger than the storage depth dimension f1 of the rear storage part 42a at the front part. Then, Chinese cabbage, cabbage and broccoli are stored in the rear storage section 42a, and carrots, cucumbers, beverages and the like are stored in the front storage section 42b having a large storage depth. That is, since the vegetable container 42 has storage parts with different storage depth dimensions in the rear part and the front part, when storing vegetables, it is configured so that the vegetables can be stored without being stacked.

冷凍温度室５０は、その上部に、急速冷凍容器７２を有する急速冷凍室７０と自動製氷機６３及び貯氷容器９６を有する貯氷室６０（図６）を仕切り部材９及び断熱仕切壁８により区画形成している。また、冷凍温度室５０は、急速冷凍室７０の下方に、容器８２、８３、８４を有する冷凍室８０を、仕切り部材９により区画形成している。 In the freezing temperature chamber 50, a quick freezing chamber 70 having a quick freezing container 72 and an ice storage chamber 60 (FIG. 6) having an automatic ice maker 63 and an ice storage container 96 are partitioned by the partition member 9 and the heat insulating partition wall 8. doing.

蒸発器１５は、箱体２の下部に設けられた圧縮機１６から送られ凝縮器（図示せず）にて液化した冷媒を内部で蒸発させ、冷媒の気化熱で冷蔵温度室２０及び冷凍温度室５０に送る冷気を冷却する。送風機１２は、蒸発器１５で冷却した冷気を、制御装置（図示せず）及び操作パネル７４（図１）からの指令により冷蔵温度室２０または冷凍温度室５０に循環させ、各貯蔵室３０、４０、６０、７０、８０を所定の低温温度に冷却保持している。
ここで、野菜室４０を有する冷蔵温度室２０と、急速冷凍室７０を有する冷凍温度室５０との間に設けられた断熱仕切壁８の実施例を図２により説明する。断熱仕切壁８は、断熱材５を内蔵し、上方に野菜容器４２の大きい収納深さ寸法ｆ2を有する前部収納部４２bを有する断熱仕切壁前部８eと、前部８eより野菜室側に突出した断熱仕切壁後部８aとを有し、断熱仕切壁後部８aの下部に、急速冷凍室を上方に拡大する拡大部８bを有し、拡大部８bを急速冷凍室冷却用冷気ダクト８fとして形成してある。つまり、急速冷凍室内に上面が開口した急速冷凍容器７２を設置し、急速冷凍容器７２内に貯蔵された食品を所定のスピードで凍結できる冷気を吐出する冷気ダクト８fを、急速冷凍容器７２の上面開口上方に設けられるように、断熱仕切壁８の後部拡大部８bを形成している。つまり、貯蔵食品をホームフリージングする急速冷凍室は、通常の冷凍食品を貯蔵する冷凍室よりその冷却用冷気の循環量を大幅に増加させた冷却用冷気を直接食品に吹き当てる必要があるので、冷却用冷気を吐出する冷気ダクト８fを急速冷凍容器７２の上面開口上方に設け、下方に向かって冷気を吐出する構成とするために、断熱仕切壁８の後部に拡大部８bを形成している。 The evaporator 15 evaporates the refrigerant sent from the compressor 16 provided in the lower part of the box 2 and liquefied in the condenser (not shown) inside, and the refrigeration temperature chamber 20 and the freezing temperature by the heat of vaporization of the refrigerant. The cool air sent to the chamber 50 is cooled. The blower 12 circulates the cool air cooled by the evaporator 15 to the refrigeration temperature chamber 20 or the freezing temperature chamber 50 according to a command from a control device (not shown) and the operation panel 74 (FIG. 1). 40, 60, 70, and 80 are cooled and held at a predetermined low temperature.
An embodiment of the heat insulating partition wall 8 provided between the refrigerated temperature chamber 20 having the vegetable chamber 40 and the freezing temperature chamber 50 having the quick freezing chamber 70 will be described with reference to FIG.

A rear enlarged portion 8b of the heat insulating partition wall 8 is formed so as to be provided above the opening. In other words, the quick freezer that freezes the stored food at home freezes the food directly with the cooling air that greatly increases the circulation amount of the cooling air than the freezer that stores the normal frozen food. In order to provide a cool air duct 8f for discharging cool air for cooling above the upper surface opening of the quick freezing container 72 and discharge cool air downward, an enlarged portion 8b is formed at the rear of the heat insulating partition wall 8. .

さらに、冷気ダクト８ｆの下端は断熱壁前部８ｅの下端と略同一の高さ（±1cm以内）としてある。つまり、冷気ダクト８ｆを拡大部８ｂの中に設けたということである。これにより、急速冷凍室７０の天井面が略平面となるので、急速冷凍室７０内の高さ方向の収納空間を有効に使うことができ、急速冷凍容器７２の収納深さ寸法を確保しながら急速冷凍室７０が占める高さ方向の容積を小さくすることができる。また、冷気ダクト８ｆの高さ方向の大きさは拡大部８ｂの大きさ以下に限定されるが、急速冷凍に必要な冷気循環量を通過させる冷気ダクト８ｆの断面積を確保するためには、横方向の大きさを大きくすればよい。また、冷気ダクト８ｆを冷蔵庫１の前方から見た場合の断熱仕切壁８の投影面に収めれば、引出ドア７１を開閉した場合に食品と冷気ダクト８ｆとの衝突を回避することができる。 Furthermore, the lower end of the cold air duct 8f has substantially the same height (within ± 1 cm) as the lower end of the heat insulating wall front portion 8e. That is, the cold air duct 8f is provided in the enlarged portion 8b. As a result, the ceiling surface of the quick freezing chamber 70 is substantially flat, so that the storage space in the height direction in the quick freezing chamber 70 can be used effectively, and the storage depth dimension of the quick freezing container 72 is secured. The volume in the height direction occupied by the quick freezer 70 can be reduced. Moreover, although the size of the cold air duct 8f in the height direction is limited to the size of the enlarged portion 8b or less, in order to ensure the cross-sectional area of the cold air duct 8f that passes the amount of the cold air circulation necessary for quick freezing, What is necessary is just to enlarge the magnitude | size of a horizontal direction. Moreover, if the cold air duct 8f is stored on the projection surface of the heat insulating partition wall 8 when viewed from the front of the refrigerator 1, a collision between the food and the cold air duct 8f can be avoided when the drawer door 71 is opened and closed.

本願発明の一実施例は、冷蔵温度室２０と、冷蔵温度室２０の下部に設けられ、引出ドア４１と容器４２を有する野菜室４０と、野菜室４０の下方に設けられ、引出ドア６１、７１、８１と容器７２、８２、８３、８４、９６を有する冷凍温度室５０と、野菜室４０と冷凍温度室５０を仕切り、断熱材５を内蔵する断熱仕切り８とを備えた冷蔵庫において、断熱仕切り８は前部８ｅと後部８ａから構成され、断熱仕切りの前部８ｅの上側は、断熱仕切りの後部８ａの上側より低くなっており、断熱仕切りの前部８ｅの下側は、断熱仕切りの後部８ａの下側より低くなっており、断熱仕切りの後部８ａの下側に接する冷気ダクト８ｆと、断熱仕切り８の下に設けられ、その底面に金属板７３を有する容器７２とを備え、ダクト８ｆの下部と、断熱仕切り前部８ｅの下側は略同一の高さであることを特徴とする。 One embodiment of the present invention is a refrigerated temperature chamber 20, a lower portion of the refrigerated temperature chamber 20, a vegetable chamber 40 having a drawer door 41 and a container 42, a lower portion of the vegetable chamber 40, a drawer door 61, In a refrigerator provided with a freezing temperature chamber 50 having 71 and 81 and containers 72, 82, 83, 84, and 96, a vegetable room 40 and a freezing temperature chamber 50, and a heat insulating partition 8 containing a heat insulating material 5. The partition 8 is composed of a front portion 8e and a rear portion 8a. The upper side of the front portion 8e of the heat insulating partition is lower than the upper side of the rear portion 8a of the heat insulating partition, and the lower side of the front portion 8e of the heat insulating partition is A cool air duct 8f that is lower than the lower side of the rear part 8a and is in contact with the lower side of the rear part 8a of the heat insulating partition, and a container 72 that is provided under the heat insulating partition 8 and has a metal plate 73 on the bottom surface thereof. The bottom of 8f, Lower side of the partition front 8e is characterized in that substantially the same height.

この構成により、急速冷凍室７０の天井面が略平面となるので、急速冷凍室７０内の高さ方向の収納空間を有効に使うことができ、急速冷凍容器７２の収納深さ寸法を確保しながら急速冷凍室７０が占める高さ方向の容積を小さくすることができる。 With this configuration, since the ceiling surface of the quick freezing chamber 70 is substantially flat, the storage space in the height direction in the quick freezing chamber 70 can be used effectively, and the storage depth dimension of the quick freezing container 72 is secured. However, the volume in the height direction occupied by the quick freezer 70 can be reduced.

次に、ホームフリージングができる急速冷凍室７０の一実施例を図３により説明する。図３は、図２の急速冷凍容器７２の周辺の要部拡大図である。急速冷凍容器７２の上面開口部７２f上方に、冷気を吹き込む冷気ダクト８fを設けて、食品７５を所定のスピードで凍結できる構成にしてある。所定のスピードとは、ホームフリージングをする食品のうまみを保持するために、通常の冷凍室８０内で凍結する時間の、例えば、半分以下の時間で凍結する構成にしてある。そのために、冷気ダクト８fを急速冷凍容器７２の上面開口部７２fの上方に設けて、冷気ダクト８ｆから上面開口部７２ｆに急速冷凍容器７２内の食品を冷却するために吐出する冷気の循環量を、通常の冷凍室冷却冷気の循環量の倍以上に設定してある。従って、循環量の増加した冷却冷気の循環によりパッキン７１a外周縁に結露しないように、急速冷凍容器７２の上面開口フランジ７２aと断熱仕切壁８との間をシールするシール部材８cを、断熱仕切壁８下面に設置してある。また、貯蔵食品７５を冷却した冷気が循環し易いように、急速冷凍容器７２の前面側壁に通風孔７２eを設けてあるので、通風孔７２eから冷気通路７０aに循環する冷気により、パッキン７１ｃ外周縁が結露しないように、ドア内板７１ｂと仕切り部材９との間をシールするシール部材９aを、ドア内板７１ｂ下部に設置してある。 Next, an embodiment of the quick freezer 70 capable of home freezing will be described with reference to FIG. FIG. 3 is an enlarged view of a main part around the quick freezing container 72 of FIG. A cold air duct 8f for blowing cold air is provided above the upper surface opening 72f of the quick freezing container 72 so that the food 75 can be frozen at a predetermined speed. The predetermined speed is configured to freeze in, for example, half or less of the time for freezing in the normal freezer compartment 80 in order to maintain the taste of food freezing at home. For this purpose, the cold air duct 8f is provided above the upper surface opening 72f of the quick freezing container 72, and the circulation amount of the cold air discharged to cool the food in the quick freezing container 72 from the cold air duct 8f to the upper surface opening 72f is set. It is set to be more than twice the circulation amount of the normal freezer compartment cooling cold air. Therefore, the sealing member 8c that seals between the upper surface opening flange 72a of the quick-frozen container 72 and the heat insulating partition wall 8 is provided with a heat insulating partition wall so that condensation does not occur on the outer periphery of the packing 71a due to circulation of the cooling air having increased circulation amount. 8 is installed on the lower surface. Moreover, since the air vent 72e is provided in the front side wall of the quick-frozen container 72 so that the cool air which cooled the stored food 75 may circulate, outer periphery of packing 71c by the cold air which circulates from the air vent 72e to the cool air channel | path 70a. In order to prevent condensation, a seal member 9a that seals between the door inner plate 71b and the partition member 9 is provided below the door inner plate 71b.

また、ホームフリージングでは、食品の細胞膜を破壊しないように凍結するために、食品の水分の大部分が凍結する温度帯(−５℃から−１℃)を短時間で通過するのが望ましく、出来るだけ速く凍結するために、合成樹脂製の急速冷凍容器７２内面に熱良導性の金属板７３を設置している。金属板７３の詳細を図４により説明する。図４は図３のＤ−Ｄ線縦断面図である。熱良導性の金属板７３は、合成樹脂製の急速冷凍容器７２の底板部を覆う底部７３aと、底部７３aと連続して、急速冷凍容器７２の左右側壁部を覆う側部７３bを有し、側部７３bの上面フランジ７３c端面を、急速冷凍容器７２のフランジ溝７２c内に係止している。従って、急速冷凍容器７２に貯蔵された食品は、冷気ダクト８fより降り注ぐように吐出された冷気により冷却されるのと同時に、熱良導性の金属板底部７３a及び熱良導性の金属板側部７３bにより冷却されるので、その凍結スピードをより速くすることができる。なお、本実施例では、金属板７３は急速冷凍容器７２の底板部と側壁部を覆っているが、金属板７３が底板部のみを覆う容器でも、急速冷凍は可能である。 Further, in home freezing, it is desirable to pass through a temperature range (−5 ° C. to −1 ° C.) where most of the water content of the food freezes in a short time in order to freeze the cell membrane of the food without destroying it. In order to freeze as fast as possible, a heat-conductive metal plate 73 is installed on the inner surface of the quick-frozen container 72 made of synthetic resin. Details of the metal plate 73 will be described with reference to FIG. 4 is a longitudinal sectional view taken along the line DD of FIG. The heat conductive metal plate 73 has a bottom portion 73a that covers the bottom plate portion of the quick-frozen container 72 made of synthetic resin, and a side portion 73b that covers the left and right side walls of the quick-frozen container 72 continuously with the bottom portion 73a. The end surface of the upper surface flange 73 c of the side portion 73 b is locked in the flange groove 72 c of the quick freezing container 72. Accordingly, the food stored in the quick freezing container 72 is cooled by the cold air discharged so as to pour down from the cold air duct 8f, and at the same time, the heat conductive metal plate bottom 73a and the heat conductive metal plate side. Since it is cooled by the portion 73b, the freezing speed can be further increased. In the present embodiment, the metal plate 73 covers the bottom plate portion and the side wall portion of the quick freezing container 72, but quick freezing is possible even in a container in which the metal plate 73 covers only the bottom plate portion.

なお、冷気ダクト８ｆの冷気吐出口は、断熱仕切壁８の傾斜部８ｇよりも奥に配置されるように構成される。このことによって、冷気ダクト８ｆを通って吐出される冷気は傾斜部８ｇの下側にあたって急速冷凍容器７２側に案内される。前記冷気吐出口の位置は、傾斜部８ｇの位置によって変更できるものであるが、冷蔵庫奥行方向の中央部に配置すれば、急速冷凍容器７２内を前部と後部で同じように冷却できる。この際は、冷気吐出口から吐出される冷気を鉛直下向きの流れとすべく案内するように冷気吐出口を構成することが望ましい。また、冷気吐出口を冷蔵庫奥行方向中央部よりもさらに奥側に配置すれば、冷気吐出口からの冷気を必ずしも鉛直方向下向きの流れとする必要は無く、前方であって下方への流れとすれば急速冷凍容器７２の奥側から手前側まで冷却することができる。 The cold air discharge port of the cold air duct 8f is configured to be disposed behind the inclined portion 8g of the heat insulating partition wall 8. Thus, the cold air discharged through the cold air duct 8f is guided to the quick freezing container 72 side at the lower side of the inclined portion 8g. The position of the cold air discharge port can be changed depending on the position of the inclined portion 8g, but if it is arranged at the center in the refrigerator depth direction, the inside of the quick freezing container 72 can be cooled in the same manner at the front and rear. In this case, it is desirable to configure the cold air discharge port so as to guide the cold air discharged from the cold air discharge port to be a vertically downward flow. Further, if the cold air discharge port is arranged further to the back than the center part in the depth direction of the refrigerator, the cold air from the cold air discharge port does not necessarily have to be a downward flow in the vertical direction, and the flow is forward and downward. For example, the quick freezing container 72 can be cooled from the back side to the front side.

なお、急速冷凍能力は、冷気の温度、風量及び風速に依存するものであるが、風量と風速とを比較すると風速による効果が大きいものと考えられる場合があり、本例では、冷気ダクト８ｆ内の冷気の通り道となる断面積を冷気吐出口へ向かって狭める構成とすることによって風速を上げるように構成している。冷気吐出口は、図３に示すように冷気ダクト８ｆの下面を急速冷凍容器７２に向かって曲げられて構成されているが、冷気の速度が高い場合には、断熱仕切壁８の傾斜部８ｇの下部に冷気が吹き付けられ、傾斜部８ｇの冷気吹き付け部分は高い断熱能力を要求されることとなる。この場合は、断熱仕切壁８の傾斜部８ｇの上部は後部収納部４２ａの底面部４２ｃで覆うように構成することが有効である。すなわち、底面部４２ｃは略水平とするために、傾斜部８ｇの上方に位置する底面部４２ｃの部分は、底面部４２ｃの他の部分よりも断熱仕切壁８からの距離を多く取ることができるため冷熱が他の部分よりも伝わりにくくなる。また、この距離を多く取った部分をさらに断熱することもさらに有効である。
ここで、一般家庭用冷蔵庫に貯蔵する冷凍食品例およびホームフリージングを行う食材例について、表１により説明する。 The quick refrigeration capacity depends on the temperature, the air volume, and the wind speed of the cold air. However, when the air volume and the air speed are compared with each other, it may be considered that the effect of the air speed is large. It is configured to increase the wind speed by narrowing the cross-sectional area that becomes the path of the cool air toward the cool air discharge port. As shown in FIG. 3, the cold air outlet is formed by bending the lower surface of the cold air duct 8f toward the quick freezing container 72. However, when the speed of the cold air is high, the inclined portion 8g of the heat insulating partition wall 8 is formed. Cold air is sprayed on the lower part of the slab, and the cold air sprayed portion of the inclined portion 8g is required to have a high heat insulation capability. In this case, it is effective to cover the upper portion of the inclined portion 8g of the heat insulating partition wall 8 with the bottom surface portion 42c of the rear storage portion 42a. That is, since the bottom surface portion 42c is substantially horizontal, the portion of the bottom surface portion 42c located above the inclined portion 8g can take a greater distance from the heat insulating partition wall 8 than the other portions of the bottom surface portion 42c. Therefore, it becomes harder to transmit cold heat than other parts. It is also more effective to further insulate the portion where the distance is increased.
Here, an example of frozen food stored in a general household refrigerator and an example of food that performs home freezing will be described with reference to Table 1.

表１は貯蔵食品の収納高さ寸法別に例示したものである。表１に示す如く、その収納高さ寸法は、分類１（40〜70ｍｍ）、分類２（70〜100ｍｍ）、分類３（100ｍｍ〜150ｍｍ）、分類４（150ｍｍ以上）の約４段階に分類している。また、冷凍食品例の右側には、それぞれの分類の冷凍食品例の使用頻度が示されており、さらにその右側には、各分類の冷凍食品例のうち、ホームフリージングを行う食材の例が示されている。

Table 1 shows examples of stored foods according to storage height dimensions. As shown in Table 1, the storage height is classified into approximately four levels: Class 1 (40 to 70 mm), Class 2 (70 to 100 mm), Class 3 (100 mm to 150 mm), and Class 4 (150 mm or more). ing. On the right side of the frozen food examples, the frequency of use of each category of frozen food examples is shown, and on the right side of the frozen food examples of each category, examples of ingredients that perform home freezing are shown. Has been.

なお、表１に示す食品例で同一の食品名が分類の二箇所に表示してある食品は、長手方向を水平にする横置きの場合を、例えば、パイシ−ト紙パック類（１）と表示し、長手方向を鉛直にする縦置きの場合を、例えば、パイシ−ト紙パック類（２）と表示してある。また、表１に示す食品例で、牛乳パック類（１）、牛乳パック類（２）は共に、牛乳パック類を再利用して、スープ類等のホームフリージング食品を作る場合を示している。 In addition, the food in which the same food name is displayed in two places of the classification in the food examples shown in Table 1 is the case where the longitudinal direction is horizontal, for example, pie sheet paper packs (1) For example, the case where the longitudinal direction is set to be vertical is displayed as pie sheet paper packs (2). Also, in the food examples shown in Table 1, the milk packs (1) and the milk packs (2) both show the case where the milk packs are reused to make home freezing foods such as soups.

表１のホームフリージング食材例の欄に示すように、ホームフリージングを行うほとんどの食材の高さ寸法は、分類１及び分類２に分けられる100ｍｍ以下となっている。そこで、ホームフリージングするための急速冷凍容器７２は、その収納深さ寸法を70mmから100mmとすれば、ホームフリージング食材例の大部分を収納できる。従って、本実施例のホームフリージングができる急速冷凍容器の収納深さ寸法ｆ3（図２）は表１の分類２に示す70mmから100mmに設定してある。 As shown in the column of examples of home freezing ingredients in Table 1, the height dimension of most ingredients that perform home freezing is 100 mm or less, which can be divided into classification 1 and classification 2. Therefore, the quick-freezing container 72 for home freezing can accommodate most of the home freezing food examples if the storage depth is 70 mm to 100 mm. Therefore, the storage depth f3 (FIG. 2) of the quick-frozen container capable of home freezing in this embodiment is set from 70 mm to 100 mm shown in Category 2 of Table 1.

なお、容器の収納深さ寸法とは、容器の底面から左右側壁の上端までの鉛直方向の距離、または、容器の底面から容器の上にある他の容器等の下端までの鉛直方向の距離のうち、小さい方とする。 The storage depth dimension of the container is a vertical distance from the bottom surface of the container to the upper ends of the left and right side walls, or a vertical distance from the bottom surface of the container to the lower ends of other containers on the container. The smaller one is used.

本願発明の一実施例は、外箱３と、内箱４と、外箱３と内箱４との間に発泡断熱体５を充填した箱体１と、箱体１内に区分けされた冷蔵温度室２０、冷凍温度室５０とを備えた冷蔵庫において、冷凍温度室５０は、冷気を吐出する冷気ダクト８ｆと、冷気ダクト８ｆの下方に設けられ、底面に金属板７３を有する容器７２とを有し、金属板７３を有する容器７２の収納深さ寸法は７０〜１００ｍｍであることを特徴とする。 One embodiment of the present invention includes an outer box 3, an inner box 4, a box body 1 in which a foam insulation 5 is filled between the outer box 3 and the inner box 4, and refrigeration partitioned into the box body 1. In the refrigerator including the temperature chamber 20 and the freezing temperature chamber 50, the freezing temperature chamber 50 includes a cold air duct 8f that discharges cold air, and a container 72 that is provided below the cold air duct 8f and has a metal plate 73 on the bottom surface. The container 72 having the metal plate 73 has a storage depth of 70 to 100 mm.

この構成により、ホームフリージングを行う食材の大部分を収納できる急速冷凍容器７２の収納深さ寸法を確保しながら、急速冷凍室７０が占める高さ方向の容積を小さくすることができ、また、冷気ダクト８ｆから食品までの距離を小さくして、冷凍速度を速くすることができる。 With this configuration, it is possible to reduce the volume in the height direction occupied by the quick freezing chamber 70 while ensuring the storage depth dimension of the quick freezing container 72 that can store most of the ingredients for home freezing. The freezing speed can be increased by reducing the distance from the duct 8f to the food.

なお、図２に示す如く、急速冷凍容器７２の上面開口に降り注ぐように冷気を吐出する冷気ダクト８fを急速冷凍容器７２の上面開口上方に設ける必要があり、冷気ダクト８ｆを断熱壁の拡大部８ｂに収めることができることから、急速冷凍容器７を設置する急速冷凍室は、断熱仕切壁８の下部に設置することが望ましい。従って、本実施例では、冷凍温度室の上部に急速冷凍室７０を、その下部に通常の冷凍室８０を設けてある。 In addition, as shown in FIG. 2, it is necessary to provide the cold air duct 8f which discharges cold air so that it may pour into the upper surface opening of the quick-freezing container 72, and the cold air duct 8f is provided in the enlarged part of the heat insulation wall. Since it can be accommodated in 8b, it is desirable to install the quick freezing chamber in which the quick freezing container 7 is installed in the lower part of the heat insulating partition wall 8. Therefore, in this embodiment, the quick freezing chamber 70 is provided above the freezing temperature chamber, and the normal freezing chamber 80 is provided below the freezing temperature chamber.

また、急速冷凍室のドア７１は、冷凍室のドア８１と別体で設けてある。冷凍室中に急速冷凍室を設け、それらのドアを同一とした場合、急速冷凍中に冷凍室８０に食品を入れたり取り出したりする場合、急速冷凍を中断しなければならず、急速冷凍の時間が長くなってしまう。特に、食品の温度が−５〜−１℃である温度が長くなると、氷結晶が生成して食品のうまみを逃がしてしまう。本実施例では、急速冷凍室７０と冷凍室８０のドアを別体としているので、冷凍室のドアを開けても急速冷凍を継続でき、素早い冷凍をすることができる。 The quick freezer door 71 is provided separately from the freezer door 81. If a quick freezer is provided in the freezer and the doors are the same, when the food is put into or taken out from the freezer 80 during the quick freezing, the quick freezing must be interrupted, and the quick freezing time Will become longer. In particular, when the temperature of the food is −5 to −1 ° C., ice crystals are generated and the food taste is lost. In this embodiment, since the doors of the quick freezing chamber 70 and the freezing chamber 80 are separated, the quick freezing can be continued even if the freezing door is opened, and quick freezing can be performed.

本願発明の一実施例は、冷凍温度室５０は、金属板７３を有する容器７２の下方に設けられた複数の容器８２、８３、８４を備え、金属板７３を有する容器７２は他の容器８２、８３、８４と別体で引出ドア７１を備えたことを特徴とする。 In one embodiment of the present invention, the freezing temperature chamber 50 includes a plurality of containers 82, 83, 84 provided below a container 72 having a metal plate 73, and the container 72 having the metal plate 73 is another container 82. 83, 84, and a drawer door 71 provided separately.

この構成により、急速冷凍中に冷凍室８０の複数の容器８２、８３、８４中の他の食品を取り出す場合に、急速冷凍を中断しないので、素早い冷凍を行うことができる。 With this configuration, when other foods in the plurality of containers 82, 83, 84 in the freezer compartment 80 are taken out during quick freezing, quick freezing is not interrupted, so that quick freezing can be performed.

ところで、既に冷凍室８０に貯蔵してある食品の上に新しく食品を重ねて貯蔵すると、既に貯蔵してある食品の食品温度が、新しい食品のために上昇し、鮮度が落ちる原因になる。特に、ホームフリージングを行った食品の上に別の食品を新たに貯蔵すると、ホームフリージングを行った食品の温度が上昇してしまい、このときに食品の温度が−５℃を超えてしまうと、再冷凍時に氷結晶が生成し、食品細胞が傷つき食品のうまみが流出する原因になる。従って、ホームフリージングを行った食品を鮮度を保って保存するためには、貯蔵食品を積み重ねを少なくする冷凍室構造が必要になる。 By the way, if a new food is stored on top of the food already stored in the freezer compartment 80, the food temperature of the already stored food rises due to the new food, which causes a decrease in freshness. In particular, when another food is newly stored on top of the food that has been subjected to home freezing, the temperature of the food that has been subjected to home freezing will increase, and if the temperature of the food exceeds -5 ° C at this time, Ice crystals are formed during re-freezing, causing damage to food cells and causing the food to escape. Therefore, in order to preserve foods that have been subjected to home freezing while maintaining freshness, a freezer structure that reduces the stacking of stored foods is required.

表１の分類の冷凍食品例のうち、高さ寸法が小さい分類１の食品は、体積が小さく熱容量も小さいため、他の食品と積み重ねられた場合に温度上昇が大きくなる。分類１の食品はホームフリージングを行う頻度が高いので、食品の積み重ねを極力抑えて鮮度を保つ必要がある。 Among the frozen food examples of the classification of Table 1, the food of the classification 1 having a small height dimension has a small volume and a small heat capacity, so that when it is stacked with other food, the temperature rise is large. Since foods of category 1 are frequently subjected to home freezing, it is necessary to keep food freshness by suppressing the stacking of foods as much as possible.

そこで、本実施例の冷蔵庫は、冷凍室８０に三段の容器８２、８３、８４を設け、上段の容器８２（第三の容器）の収納深さを40〜70ｍｍとして、分類１の食品専用としている。分類１の食品は、冷凍庫に貯蔵される食品の約３０％を占めているので、同一の高さでの冷凍室の水平方向の面積の７０％以上の底面積を持つ専用の容器を備えても十分なくらい使用頻度がある。これにより、急速冷凍を行った行わなかったにかかわらず、分類１の食品は上段の容器に貯蔵して、冷凍庫に保存中に食品の積み重ねによる温度上昇を防ぐことができる。 Therefore, the refrigerator of this embodiment is provided with three-stage containers 82, 83, 84 in the freezer compartment 80, and the upper container 82 (third container) has a storage depth of 40 to 70 mm. It is said. Category 1 food accounts for about 30% of the food stored in the freezer, so it has a dedicated container with a bottom area of 70% or more of the horizontal area of the freezer at the same height. There is enough use frequency. Thereby, irrespective of not performing quick freezing, the foodstuff of classification | category 1 can be stored in an upper container, and the temperature rise by stacking of foodstuffs can be prevented during preservation | save in a freezer.

本願発明の一実施例は、外箱３と、内箱４と、外箱３と内箱４との間に発泡断熱体５を充填した箱体１と、箱体１内に区分けされた冷蔵温度室２０、冷凍温度室５０とを備えた冷蔵庫において、冷凍温度室５０は、収納深さ寸法が４０〜７０ｍｍである容器を備えたことを特徴とする。 One embodiment of the present invention includes an outer box 3, an inner box 4, a box body 1 in which a foam insulation 5 is filled between the outer box 3 and the inner box 4, and refrigeration partitioned into the box body 1. In the refrigerator including the temperature chamber 20 and the freezing temperature chamber 50, the freezing temperature chamber 50 includes a container having a storage depth dimension of 40 to 70 mm.

この構成により、高さ寸法が70ｍｍ以下の食品を収納する専用の容器を設けて、70ｍｍ以下の食品の積み重ねを無くしたので、すでに貯蔵された食品の上に新たに貯蔵された食品が積み重ねられ、すでに貯蔵されていた食品の温度が上昇することを防ぐことができる。特に、熱容積が小さく温度上昇しやすい高さ寸法が小さい食品には、効果が大きくなる。 With this configuration, a dedicated container for storing foods with a height dimension of 70 mm or less is provided, and stacking of foods with a height of 70 mm or less is eliminated, so that newly stored food is stacked on food that has already been stored. The temperature of food that has already been stored can be prevented from rising. In particular, the effect is great for foods having a small heat volume and a small height that tends to rise in temperature.

また、本願発明は、冷凍室８０中の容器を三段にして、食品の積み重ねを少なくしているが、中段の容器８３（第二の容器）、下段の容器８４（第三の容器）も、容器の収納深さを食品の高さ寸法と使用頻度を勘案して決定することにより、段数を増やしたための冷凍室８０の高さ寸法の増大を少なく抑えることができる。 The present invention has three containers in the freezer compartment 80 to reduce food stacking, but the middle container 83 (second container) and the lower container 84 (third container) are also used. By determining the storage depth of the container in consideration of the height dimension of the food and the frequency of use, an increase in the height dimension of the freezer compartment 80 due to the increased number of stages can be suppressed.

本実施例では、中段の容器８３を収納深さを100〜150ｍｍとして、分類２と分類３の食品を収納するようにしている。また、下段の容器８４の収納深さ寸法を150〜200ｍｍとし、分類３と分類４の食品を収納するようにしている。分類４の食品例のうち、牛乳パック類（２）や、パイシート紙パック類（２）は、高さ寸法が200ｍｍをこえるが、これらのものは縦置きであり、横置きにすることによって保存することができる。中段、下段の収納深さ寸法をこのような大きさにすることで、高さを小さく抑えた冷凍室８０で、高さ寸法ごとに食品を分別して積み重ねを少なくし、鮮度を保つことができる。 In this embodiment, the container 83 in the middle stage is set to a storage depth of 100 to 150 mm, and foods of category 2 and category 3 are stored. Further, the storage depth of the lower container 84 is set to 150 to 200 mm, and foods of Category 3 and Category 4 are stored. Among the food examples of Category 4, the milk packs (2) and the pie sheet paper packs (2) have a height dimension exceeding 200 mm, but these are vertically placed and stored by being placed horizontally. be able to. By setting the storage depth dimensions of the middle and lower tiers to such a size, it is possible to maintain the freshness by separating foods according to the height dimension and reducing the stacking in the freezer compartment 80 with a reduced height. .

本願発明の一実施例は、冷凍温度室８０は、第一の容器８４と、前記第一の容器８４の上に設けられ、収納深さ寸法が前記第一の容器８４より小さい第二の容器８３と、前記第二の容器８３の上に設けられ、収納深さ寸法が前記第二の容器８３より小さい第三の容器８２とを備え、前記第三の容器８２は、収納深さ寸法が４０〜７０ｍｍであることを特徴とする。 In one embodiment of the present invention, the freezing temperature chamber 80 is provided on the first container 84 and the first container 84, and the second container having a storage depth smaller than the first container 84. 83 and a third container 82 provided on the second container 83 and having a storage depth dimension smaller than that of the second container 83. The third container 82 has a storage depth dimension. It is 40-70 mm.

この構成により、食品を高さ寸法ごとに整理して収納することができるので、第二の容器、第三の容器の食品の積み重ねを少なくして、食品の温度上昇を防ぐことができ、また、冷凍室８０の高さ寸法も小さく抑えることができる。 With this configuration, food can be organized and stored by height, so the food in the second container and the third container can be reduced to prevent the food from rising in temperature. And the height dimension of the freezer compartment 80 can also be suppressed small.

次に、冷凍室８０に設けた三種類の容器８２、８３、８４の引き出し方法の一実施例を図５により説明する。 Next, an example of a method for pulling out the three types of containers 82, 83, 84 provided in the freezer compartment 80 will be described with reference to FIG.

本実施例の冷凍室は、三段の容器８２、８３、８４を設けており、上段容器８２は容器深さを40〜70mmとし、高さ70mm以下の薄い食品を収納するようにしてある。高さ寸法の小さい食品は、表面積と比べた体積が小さくなっており、かつ、積み重ねないようにしていているので、温かい外気に触れたときに食品の温度が上昇しやすくなっている。食品が外気に触れ、その温度が−５℃以上に上昇した場合も、前述した場合と同様に食品のうまみが流出する原因になる。そこで、本実施例の冷凍室の三段の容器８２、８３、８４は次のような引出方法を取る。 The freezer compartment of the present embodiment is provided with three-stage containers 82, 83, and 84, and the upper container 82 has a container depth of 40 to 70 mm and accommodates thin foods having a height of 70 mm or less. A food with a small height has a small volume compared to the surface area and is not stacked, so that the temperature of the food tends to rise when it is exposed to warm outside air. When the food comes into contact with the outside air and the temperature rises to −5 ° C. or higher, the taste of the food flows out as described above. Therefore, the three-stage containers 82, 83, 84 of the freezer compartment of this embodiment take the following drawing method.

図５（a）は、中段容器８３と下段容器８４とを引出ドア８１と共に所定寸法（Ｌ1）開放した状態を示す。下段容器８４は、冷凍室ドア８１と一緒に前後に移動可能に構成されている。また、中段容器８３の把手８３ａは、下段容器８４と係合しており、引出ドア８１を引出すと、下段容器８４と中段容器８３が一緒に引出され、図５(a)のようになる。この状態では、中段容器８３内の貯蔵食品の出し入れが出来る。そして、引出ドア８１の開放寸法Ｌ1のままで、中段容器８３の把手部８３aに手指を掛けて中段容器８３を冷蔵庫の奥側にスライドすると、図５（b）に示すようになり、下段容器８４への貯蔵食品の出し入れができる。また、図５（a）の状態から引出ドア８１をさらに開放し、図５（c）に示すように、引出ドア８１の開放寸法が、全開時の半分以上であるＬ2になると、上段容器８２の左右両端下側に設けられた突起８２ｂが中段容器８３の左右側壁の上部より外側の左右に伸びるフランジ部上側に設けられた突起８３ｂに引っかかって上段容器８２が引き出されて、上段容器８２の把手部８２aが、急速冷凍室ドア７１前面よりＬ3寸法だけ突出する。この状態で上段容器の把手部８２aに手指を掛けて上段容器８２を冷蔵庫の手前にスライドすると、図５（d）に示すように、上段の容器８２内への貯蔵食品の出し入れが出来る。 FIG. 5A shows a state in which the middle container 83 and the lower container 84 are opened together with the drawer door 81 by a predetermined dimension (L1). The lower container 84 is configured to be movable back and forth together with the freezer compartment door 81. Further, the handle 83a of the middle container 83 is engaged with the lower container 84, and when the drawer door 81 is pulled out, the lower container 84 and the middle container 83 are pulled out together as shown in FIG. 5 (a). In this state, the stored food in the middle container 83 can be taken in and out. When the middle container 83 is slid to the back side of the refrigerator with the finger on the handle 83a of the middle container 83 with the opening dimension L1 of the drawer door 81 remaining, the result is as shown in FIG. The stored food can be taken in and out of 84. Further, when the drawer door 81 is further opened from the state of FIG. 5A, and the opening dimension of the drawer door 81 is L2, which is half or more of the fully opened state, as shown in FIG. The protrusions 82b provided on the lower sides of the right and left ends of the upper container 82 are pulled out by hooking on the protrusions 83b provided on the upper side of the flange portion extending to the left and right outside the upper part of the left and right side walls of the middle container 83, and the upper container 82 is pulled out. The handle portion 82a protrudes from the front surface of the quick freezer compartment door 71 by the dimension L3. When the upper container 82 is slid to the front of the refrigerator by placing a finger on the handle 82a of the upper container in this state, the stored food can be taken in and out of the upper container 82 as shown in FIG. 5 (d).

以上のように構成すれば、一個の冷凍室引出ドア８１内に三段の容器を設置して、その使い勝手を良好に出来ると共に、三段の容器のうち最も収納深さ寸法部が小さい上段容器８２を、不要なときには引き出さないので、上段容器８２内に貯蔵した、冷凍食品の中で最も食品厚さの薄い食品、つまり、冷凍食品の中で最も熱容量の少ない食品類の温度上昇を防ぐことができる。これによって、食品の新鮮度が失われづらい冷蔵庫構造を提供できる。 If comprised as mentioned above, while installing the three-stage container in one freezer compartment drawer door 81 and making it easy to use, the upper-stage container having the smallest storage depth dimension portion among the three-stage containers. 82 is not pulled out when it is not required, so that the food with the thinnest food thickness among the frozen foods stored in the upper container 82, that is, the food with the smallest heat capacity among the frozen foods, is prevented from rising. Can do. Thereby, it is possible to provide a refrigerator structure in which the freshness of food is not easily lost.

また、上段容器は、冷凍室の最上段にあり、その収納深さ寸法が小さいため、仕切り部材７に隠れて把手８２ａが見えにくくなっている。引出ドア８１と下段容器８４を大きく引出したときに、上段容器８２をその把手８２ａが見えるくらいに引出すことにより、上段容器８２を引出して中の食品を出し入れしやすくなっている。 Moreover, since the upper container is in the uppermost stage of the freezer compartment and the storage depth is small, it is difficult to see the handle 82a behind the partition member 7. When the drawer door 81 and the lower container 84 are pulled out largely, the upper container 82 is pulled out to the extent that the handle 82a can be seen, so that the upper container 82 can be pulled out and food inside can be easily taken in and out.

本願発明の一実施例は、第一の容器８４は冷凍室の引出ドア８１と一緒に前後に移動し、第一の容器８４が全移動量の半分引出されたときに、第三の容器８２は連動して引出されておらず、第一の容器８４が全移動量引出されたときに、第三の容器８２は引出されることを特徴とする冷蔵庫。 In one embodiment of the present invention, the first container 84 moves back and forth together with the freezing room drawer door 81, and when the first container 84 is pulled out by half of the total movement amount, the third container 82 is moved. The refrigerator is characterized in that the third container 82 is withdrawn when the first container 84 is withdrawn in total without being pulled out in conjunction with each other.

この構成により、高さ寸法が小さく温まりやすい食品を収納してある第三の容器が引出される回数を減らすことができ、第三の容器中の食品の温度上昇を抑えて鮮度を保つことができる。 This configuration can reduce the number of times the third container that holds food that is easy to warm with a small height is pulled out, and keeps the freshness by suppressing the temperature rise of the food in the third container. it can.

次に、前述の図１のＢ−Ｂ線縦断面図を示す図６について説明する。貯氷室６０が急速冷凍室７０（図２）と、そのドア６１、７１の上端、下端の高さを略同一にして並置されている。貯氷室６０と野菜室４０との間に、後方が野菜室側に突出し、その下部に貯氷室６０を上方に拡大する拡大部８ｄを有した断熱仕切壁８を設けてあり、断熱仕切壁の拡大部８ｄに、製氷機６３を設置し、製氷機６３の下方への投影面に、その開口面が製氷機６３の投影面より大きい開口を有する貯氷容器６２を設けてあり、貯氷容器６２の収納深さ寸法ｆ9を、急速冷凍容器７２（図２）の収納深さ寸法ｆ3にほぼ一致させて形成してある。そのために、貯氷容器６２の収納深さ寸法ｆ9を、急速冷凍容器７２（図２）の収納深さ寸法ｆ3にほぼ一致させられるように、貯氷容器６２の上方に設ける製氷機６３を、断熱仕切壁の拡大部８d内に所定寸法Ｇ3を有して設置してある。 Next, FIG. 6 showing a longitudinal sectional view taken along the line BB of FIG. 1 will be described. The ice storage chamber 60 and the quick freezing chamber 70 (FIG. 2) are juxtaposed with the heights of the upper and lower ends of the doors 61 and 71 being substantially the same. Between the ice storage chamber 60 and the vegetable compartment 40, a heat insulating partition wall 8 having an enlarged portion 8d that protrudes rearward to the vegetable compartment side and expands the ice storage chamber 60 upward is provided at the lower portion thereof. An ice making machine 63 is installed in the enlarged portion 8 d, and an ice storage container 62 having an opening surface larger than the projection surface of the ice making machine 63 is provided on a projection surface below the ice making machine 63. The storage depth dimension f9 is formed so as to substantially coincide with the storage depth dimension f3 of the quick freezing container 72 (FIG. 2). For this purpose, the ice making machine 63 provided above the ice storage container 62 is provided with an adiabatic partition so that the storage depth dimension f9 of the ice storage container 62 can be made substantially equal to the storage depth dimension f3 of the quick freezing container 72 (FIG. 2). A predetermined dimension G3 is provided in the enlarged portion 8d of the wall.

従って、貯氷容器６２を出し入れする貯氷室６０の前面開口高さ寸法Ｇ2を、貯氷室６０と並置する急速冷凍室７０（図２）の前面開口高さ寸法Ｇ1とほぼ同一に出来るため、貯氷室６０前面に設置される引出ドア６１の高さ寸法と、引出ドア６１と並置される急速冷凍室７０（図２）の前面に設置される引出ドア７１の高さ寸法とをほぼ同一に出来るため、冷蔵庫の外観上スッキリした意匠感を有するとともに、図１に示すように、貯氷室引出ドア６１と急速冷凍室引出ドア７１が並置された上下に設置される、野菜室引出ドア４１と冷凍室引出ドア８１を単純な矩形形状にできるので、製造加工が容易になる。
なお、図６の貯氷容器６２の収納深さ寸法ｆ9を、図２の急速冷凍容器７２の収納深さ寸法ｆ3にほぼ一致させることは、表１で説明したように、貯氷容器６２の収納深さ寸法ｆ9を、分類２の収納高さ寸法70mmから100mmにすることであるが、このことは、従来技術の貯氷容器９３の収納深さ寸法を浅くすることにも繋がるものである。従って、貯氷容器の収納深さ寸法を浅くする場合の一実施例について、図７の製氷皿と貯氷容器の関係説明図により説明する。図７（a）が従来例の自動製氷機の製氷皿９１と貯氷容器９３の関係説明図である。貯氷容器９３の上面開口幅Ｗ3と製氷皿９１の幅Ｗ5との間には、左側余裕代Ｗ4および右側余裕代Ｗ6を設けており、その大きさはＷ６がＷ４よりもはるかに大きかった。従って、自動製氷機の製氷皿９１から落下する氷が偏心した山状９２を形成するために、貯氷容器の収納深さ寸法を大きい寸法であるｆ12に設定する必要があった。なお、製氷機自身の体積は、それ自身が冷蔵庫の貯蔵容積を減少させるために、冷蔵庫内の出来るだけ隅部に設ける傾向があったので、前記のＷ4をＷ6より小さくする傾向があった。従って、前述した製氷皿９１から落下する氷が作り出す山が偏心した山状９２を形成する傾向がより強かった。 Therefore, the front opening height dimension G2 of the ice storage chamber 60 into and out of the ice storage container 62 can be made substantially the same as the front opening height dimension G1 of the quick freezing chamber 70 (FIG. 2) juxtaposed with the ice storage chamber 60. 60 because the height dimension of the drawer door 61 installed on the front surface and the height dimension of the drawer door 71 installed on the front surface of the quick freezer compartment 70 (FIG. 2) juxtaposed with the drawer door 61 can be made substantially the same. A vegetable room drawer door 41 and a freezer compartment, which have a refreshing design on the exterior of the refrigerator and are installed above and below the ice storage compartment drawer door 61 and the quick freezer compartment drawer door 71 as shown in FIG. Since the drawer door 81 can be made into a simple rectangular shape, the manufacturing process becomes easy.
The fact that the storage depth f9 of the ice storage container 62 in FIG. 6 is substantially the same as the storage depth f3 of the quick freezing container 72 in FIG. The height dimension f9 is changed from the storage height dimension 70 mm to 100 mm in Category 2, which also leads to a reduction in the storage depth dimension of the conventional ice storage container 93. Therefore, an embodiment in which the storage depth of the ice storage container is reduced will be described with reference to the explanatory diagram of the relationship between the ice tray and the ice storage container in FIG. FIG. 7A is an explanatory view of the relationship between the ice tray 91 and the ice storage container 93 of the conventional automatic ice making machine. A left margin W4 and a right margin W6 are provided between the upper surface opening width W3 of the ice storage container 93 and the width W5 of the ice tray 91, and W6 is much larger than W4. Therefore, in order to form the mountain shape 92 in which the ice falling from the ice tray 91 of the automatic ice making machine is eccentric, it is necessary to set the storage depth dimension of the ice storage container to f12 which is a large dimension. Since the volume of the ice making machine itself tended to be provided at the corner of the refrigerator as much as possible in order to reduce the storage volume of the refrigerator, there was a tendency to make W4 smaller than W6. Accordingly, the mountain created by the ice falling from the ice tray 91 described above has a tendency to form an eccentric mountain 92.

図７（b）に示す関係が本発明の一実施例である。従来に比べ、製氷皿９６の横幅Ｗ７を拡大している。製氷皿９４を貯氷容器９６の中心付近に設置し、幅Ｗ9と貯氷容器９６の上面開口幅Ｗ7との間に、充分な余裕代Ｗ8及びＷ10（Ｗ8、Ｗ10＞Ｗ4、Ｗ6）を設けてある。つまり、自動製氷機の製氷皿９４から落下した氷が、中央部が突出した自然な山状９５を形成するために必要な寸法Ｗ8及びＷ10を設けてある。従って、貯氷容器９６の収納深さ寸法を前述のｆ12より小さいｆ13に設定できるため、貯氷容器９６の収納深さ寸法を前述の図２で示した急冷凍容器７２の収納深さ寸法ｆ3に合わせることができる。なお、この場合も製氷皿９４を有する製氷機は、それ自身が冷蔵庫の貯蔵容積を減少させるが、本発明の場合は、製氷機を図６で説明したように、断熱仕切壁の拡大部８d内に所定寸法Ｇ3を有して設置してあるので、貯氷容器９６の出し入れ時の障害にはならない構成となる。 The relationship shown in FIG. 7B is an embodiment of the present invention. Compared to the prior art, the width W7 of the ice tray 96 is enlarged. An ice tray 94 is installed near the center of the ice storage container 96, and sufficient margins W8 and W10 (W8, W10> W4, W6) are provided between the width W9 and the upper surface opening width W7 of the ice storage container 96. . That is, the dimensions W8 and W10 necessary for the ice falling from the ice tray 94 of the automatic ice making machine to form a natural mountain shape 95 whose central portion protrudes are provided. Accordingly, since the storage depth dimension of the ice storage container 96 can be set to f13 smaller than the above-described f12, the storage depth dimension of the ice storage container 96 is matched with the storage depth dimension f3 of the quick freezing container 72 shown in FIG. be able to. In this case as well, the ice making machine having the ice tray 94 itself reduces the storage capacity of the refrigerator. In the present invention, the ice making machine is expanded as shown in FIG. Since it is installed with a predetermined dimension G3 inside, it is configured not to obstruct the storage of the ice storage container 96.

本例によれば、ホームフリージングを行う食品のほとんどを収容できる高さ寸法を確保しながら、急速冷凍室の占める容積を小さくし、また、冷気ダクトと食品の距離を小さくして冷凍速度を速くすることができる。また、急速冷凍室内の空間を有効に活用し、急速冷凍室の占める容積を小さくすることができる。また、急速冷凍中に冷凍室の複数の容器中の他の食品を取り出すときに急速冷凍を中断しないので、急速冷凍時間を短縮することができる。また、この構成により、急速冷凍室室の占める高さ方向の大きさを小さくしたので、冷凍室の高さ寸法を拡大して、容器を三段とすることができる。また、高さ寸法が70ｍｍ以下の食品を収納する専用の容器を設けて、食品の積み重ねを少なくしたので、すでに貯蔵された食品の上に新たに貯蔵された食品が積み重ねられ、すでに貯蔵されていた食品の温度が上昇することを防ぐことができる。特に、熱容積が小さく温度上昇しやすい70ｍｍ以下の食品には、効果が大きくなる。また、食品を高さ寸法ごとに整理して収納することができるので、第二の容器、第三の容器も食品の積み重ねを少なくして、食品の温度上昇を防ぐことができる。また、高さ寸法が小さい食品を収納してある第三の容器が引出される回数を減らすことができ、第三の容器中の食品の温度上昇を抑えて鮮度を保つことができる。また、第一の容器が全部引出されたときには、第三の容器も引出されるので、第三の容器中の食品を取り出しやすくすることができる。また、急速冷凍を行った食品を、高さ寸法ごとに整理して冷凍室中に収容することができるので、食品の積み重ねによる温度上昇を防いで、急速冷凍の効果を保つことができる。 According to this example, while securing a height dimension that can accommodate most of the food to be subjected to home freezing, the volume occupied by the quick freezing chamber is reduced, and the distance between the cold air duct and the food is reduced to increase the freezing speed. can do. Further, the space in the quick freezer can be effectively utilized and the volume occupied by the quick freezer can be reduced. Moreover, since quick freezing is not interrupted when other foods in a plurality of containers in the freezer compartment are taken out during quick freezing, the quick freezing time can be shortened. Also, with this configuration, the size in the height direction occupied by the quick freezer compartment is reduced, so that the height dimension of the freezer compartment can be expanded and the container can be divided into three stages. In addition, since a special container for storing food with a height dimension of 70 mm or less has been provided to reduce the stacking of food, the newly stored food is stacked on top of the already stored food and has already been stored. Can prevent the food temperature from rising. The effect is particularly great for foods of 70 mm or less that have a small heat volume and easily rise in temperature. In addition, since the food can be arranged and stored for each height dimension, the second container and the third container can also reduce the accumulation of food and prevent the temperature of the food from rising. Moreover, the frequency | count that the 3rd container which accommodates the foodstuff with a small height dimension can be pulled out can be reduced, and the temperature rise of the foodstuff in a 3rd container can be suppressed, and freshness can be maintained. In addition, when the first container is completely pulled out, the third container is also pulled out, so that the food in the third container can be easily removed. Moreover, since the food which performed quick freezing can be arranged for every height dimension and accommodated in a freezer compartment, the temperature rise by stacking of food can be prevented and the effect of quick freezing can be maintained.
