【００１０】
【発明の実施の形態】
以下本発明の冷蔵庫の実施の形態を図面とともに説明する。
【００１１】
図１は本発明の冷蔵庫の実施の形態を示す野菜室付近の要部断面図であり、図２は図１に示す野菜室付近のＡ−Ａ線の要部断面図である。
【００１２】
図１において、１は冷蔵庫本体、２は野菜室、３はケースで、上に開口部を設け、上方より貯蔵物の出し入れを行う、特に大型の野菜等の貯蔵物を収納するためのものである。４は隔壁でありケース３を各々独立した部屋に仕切っている。５は冷気吐き出し口であり野菜室背壁６の上部に設けられており、冷気吐き出し口５から野菜室２へ冷気を送り込んでいる。
【００１３】
７は調湿カバーでケース３および小物ケース８の上方を覆うように野菜室２の上部に位置し、少なくとも一部は湿気を透過する性質を持ち、ケース３内および小物ケース８内を一定湿度に保つための蓋の役目をする。なお、小物ケース８はケース３の上部に位置し、小型の野菜類や小さく切った食品等の小型の貯蔵品を収納するためのものである。
【００１４】
９は小物ケースの隔壁であり、上記隔壁４の上方部に設け、ケース３に合わせて小物ケース８を各々独立した部屋に仕切っている。１０は上部仕切部で野菜室２とその上にある上部貯蔵室とを仕切っており、本図は上部貯蔵室が野菜室２と温度差の少ない冷蔵室であるため、上部仕切部１０の断熱層を薄くしてある。
【００１５】
１０ａは低温部屋用仕切開口部であり、冷気吐き出し口５の近傍の上部仕切部１０に設けてある。１１は野菜室扉、１２はアングルで野菜室扉１１にビスなどにて固着されてあり、ケース３および小物ケース８を保持し、野菜扉１１を手前にひくことにより、ケース３および小物ケース８を野菜室２内から外部へ引き出すためのものである。１３は冷蔵庫本体１内の空気を冷やすための蒸発器、１４はファンおよび駆動モータからなる送風用のファン組品である。
【００１６】
次に野菜室２内の冷気流を図１で説明すると、蒸発器１３で冷やされた冷気は、ファン組品１４にて冷蔵室へ送るダクトの一部から野菜室２へ冷気を送る冷気通路を通り、冷気吐き出し口５より野菜室２へ送り込まれる。野菜室２へ送り込まれた冷気は、調湿カバー７と上部仕切部１０との空間を通過し、調湿カバー７の前方から下へ流れる。
【００１７】
この時、野菜室２の上に冷蔵室があり、冷気吐き出し口５近傍の上部仕切部１０に低温部屋用仕切開口部１０ａがある場合、冷気吐き出し口５から野菜室２へ送り込まれた冷気は、低温部屋用仕切開口部１０ａから流入する冷蔵室側からの比較的温度の高くなった冷気と混合し、野菜凍結の心配のない野菜保存に適した冷気となる。
【００１８】
その後、冷気は野菜室扉１１とケース３の空間を通りケース３外部の下方へ流れる。ケース３外部の下を流れた冷気は、各々の冷気もどり口（図２における符号１６、１７）へ流れ込む。この間、冷気はケース３内および小物ケース８内の貯蔵品を間接的に冷却する。
【００１９】
各々の冷気もどり口へ流れ込んだ冷気は、その後、蒸発器１３に通じる蒸発器用冷気通路（図２における符号１８）を通り蒸発器１３の下部へ帰る。隔壁４は、小物ケース８があるので、確実に各部屋を仕切るため、Ｌ字型にしてある。なお、１５は野菜室２側にも断熱材を設けた冷気もどり通路であり、野菜室２に設けた各々の冷気もどり口をつなぐためのものである。
【００２０】
図２は図１に示す野菜室２付近のＡ−Ａ線の要部断面図であるが、矢印で示された冷気流は、野菜室２を正面から見たときの野菜室２の内部全体での冷気流を示している。
【００２１】
冷気吐き出し口５を通って野菜室２に送られた冷気は、調湿カバー７とケース３とで囲まれた貯蔵部周辺を、矢印が示すように分散して流れ、野菜室背壁６両端近くの一方に設けた低温部屋冷気もどり口１６、および、高温部屋３ｂ近傍の野菜室背壁６に設けた高温部屋冷気もどり口１７を通り蒸発器へ帰る。
【００２２】
この間、冷気吐き出し口５を通って野菜室２に送られた冷気は、高温部屋冷気もどり口１７より低温部屋冷気もどり口１６の開口面積が広く、かつ、冷気吐き出し口５が低温部屋冷気もどり口１６近くの上部にあるため、調湿カバー７の小物低温部屋８ａ上部を集中的に流れ、その後多くの冷気は低温部屋３ａ外側の前方および下方を通り、低温部屋冷気もどり口１６へもどる。低温部屋３ａおよび小物低温部屋８ａの外側周辺には多くの冷気が流れ、これらの部屋の貯蔵物を間接的に低温に冷却する。
【００２３】
なお、冷気吐き出し口５を通って野菜室２に送られた一部の冷気は、調湿カバー７の小物高温部屋８ｂ上部を流れ、その後高温部屋３ｂ外側の前方および下方を通り、高温部屋冷気もどり口１７へもどるため、高温部屋３ｂおよび小物高温部屋８ｂの外側周辺にはわずかの冷気が流れるのみで、これらの部屋の貯蔵物を間接的にヒーターを使うことなく比較的に温度の高い状態で保存する。
【００２４】
高温部屋３ｂおよび小物高温部屋８ｂの外側周辺に流れた冷気は比較的温度が高い状態になっているが、低温部屋冷気もどり口１６へは流れ込まないため、その比較的温度の高い冷気が低温部屋３ａを暖めるというような冷却効率の悪さは防がれる。
【００２５】
１０ｂは高温部屋用仕切開口部であり、野菜室２の上に冷蔵室のある場合、高温部屋３ｂまたは小物高温部屋８ｂの近傍の上部仕切部１０に設けてある。高温部屋用仕切開口部１０ｂから流れ出る冷蔵室側からの比較的温度の高くなった冷気は、調湿カバー７の小物高温部屋８ｂ上部を集中するように流れ、その後高温部屋３ｂ外側の前方および下方を通り、高温部屋冷気もどり口１７へもどる。高温部屋３ｂおよび小物高温部屋８ｂの外側周辺には多くの冷蔵室側からの比較的温度の高くなった冷気が流れ、これらの部屋の貯蔵物を間接的にヒーターを使うことなく比較的に温度の高い状態で保存する。
【００２６】
高温部屋冷気もどり口１７にもどった冷気は冷気もどり通路１５をとおり、低温部屋冷気もどり口１６からもどった冷気と合流し、蒸発器１３に通じる蒸発器用冷気通路１８をとおり蒸発器１３の下部へ帰る。冷気もどり通路１５には野菜室２側にも断熱材を設けてあるため、低温部屋３ａおよび小物低温部屋８ａ近傍の冷気もどり通路１５を比較的温度の高くなった冷気がとおっても、冷気もどり通路１５内での結露のおそれはなく、また、低温部屋３ａおよび小物低温部屋８ａを暖めるおそれもない。
【００２７】
なお、低温部屋用仕切開口部１０ａが、高温部屋３ｂ側へ開口面積を多くなるように片寄って、冷気吐き出し口５近傍に設けられた場合、上記低温部屋用仕切開口部１０ａから流れ出る冷蔵室側からの比較的温度の高くなった冷気が高温部屋３ｂ側へ多く流れ、高温部屋３ｂをよりいっそう温度の高い状態に保つことは明白である。
【００２８】
また、小物ケース８が隔壁にて仕切られていない場合は小物ケース８内はケース３内の低温部屋３ａや高温部屋３ｂと異なる温度になり、ケース３上部の小物ケース８は断熱空気層を設けた場合と同じ働きになり、低温部屋３ａや高温部屋３ｂが設定温度になるには時間がかかる傾向にあるが、小物ケースの隔壁９にてケース３に合わせて小物ケース８を各々独立した小物低温部屋８ａや小物高温部屋８ｂに仕切っているため、ケース３側の対応する各々の独立部屋に近い温度に小物ケース８側の各部屋もなり、容易に各々の部屋が設定された温度になる。
【００２９】
ここで、隔壁４および小物ケースの隔壁９は２重構造にしてあり、断熱効果をあげている。場合によっては、隔壁４および小物ケースの隔壁９内に断熱材をいれてもよい。また、隔壁４はケース３と各々一体に、小物ケースの隔壁９は小物ケース８と各々一体に形成してもよい。
【００３０】

During this time, the cool air sent to the vegetable compartment 2 through the cool air outlet 5 has a wider opening area of the cold room cool air return port 16 than the hot room cold air return port 17, and the cold air outlet 5 is connected to the cold room cold air return port. Since it is located near the upper portion of the low-temperature room 8a, the cold air flows intensively over the small-sized low-temperature room 8a of the humidity control cover 7, and then a large amount of cold air passes forward and downward outside the low-temperature room 3a and returns to the low-temperature room cold air return port 16. A lot of cool air flows around the outside of the low-temperature room 3a and the small-item low-temperature room 8a, and indirectly cools the storage in these rooms to a low temperature.
[0023]
Part of the cool air sent to the vegetable room 2 through the cool air outlet 5 flows in the upper part of the small high-temperature room 8b of the humidity control cover 7, and then passes in front of and below the outside of the high-temperature room 3b. To return to the return port 17, only a small amount of cool air flows around the outside of the high-temperature room 3b and the small-item high-temperature room 8b, and the stored items in these rooms are in a relatively high temperature state without using a heater indirectly. Save with.
[0024]
Although the cool air flowing around the outside of the high-temperature room 3b and the accessory high-temperature room 8b has a relatively high temperature, it does not flow into the low-temperature room cool air return port 16, so that the relatively high-temperature cool air flows into the low-temperature room. Poor cooling efficiency such as warming 3a is prevented.
[0025]
Reference numeral 10b denotes a high-temperature room partition opening, which is provided in the upper partition 10 near the high-temperature room 3b or the small accessory high-temperature room 8b when there is a refrigerator room above the vegetable room 2. The relatively high-temperature cold air from the refrigerating compartment that flows out of the high-temperature compartment partitioning opening 10b flows so as to concentrate on the upper part of the small-sized high-temperature compartment 8b of the humidity control cover 7, and thereafter forward and downward outside the high-temperature compartment 3b. And return to the hot room cold air return port 17. A relatively high temperature of cool air flows from the refrigerating room side around the outside of the high temperature room 3b and the small item high temperature room 8b, and the stored items in these rooms are relatively heated without indirectly using a heater. Store in a high state.
[0026]
The cool air returned to the high-temperature room cold air return port 17 passes through the cool air return path 15, merges with the cool air returned from the low-temperature room cool air return port 16, and passes through the evaporator cold air passage 18 leading to the evaporator 13 to the lower part of the evaporator 13. Go back. Since the cooling air return passage 15 is also provided with a heat insulating material on the vegetable room 2 side, even if cold air having a relatively high temperature passes through the cold air return passage 15 near the low-temperature room 3a and the small accessory low-temperature room 8a, the cold air returns. There is no risk of dew condensation in the passage 15 and no risk of heating the low-temperature room 3a and the accessory low-temperature room 8a.
[0027]
When the low-temperature room partition opening 10a is provided near the cool air discharge port 5 so as to be offset toward the high-temperature room 3b so as to increase the opening area, the refrigerating room side flowing out from the low-temperature room partition opening 10a. It is clear that a relatively high temperature of the cool air flows into the high temperature room 3b and keeps the high temperature room 3b at a higher temperature.
[0028]
When the accessory case 8 is not partitioned by a partition wall, the inside of the accessory case 8 has a temperature different from that of the low-temperature room 3a or the high-temperature room 3b in the case 3, and the accessory case 8 on the upper part of the case 3 is provided with an insulating air layer. It tends to take time for the low-temperature room 3a and the high-temperature room 3b to reach the set temperature. However, the small case 8 is separated from the small case 8 by the partition 9 of the small case. 8a and the small accessory high-temperature room 8b, each room on the accessory case 8 side has a temperature close to the corresponding independent room on the case 3 side, and each room easily reaches the set temperature.
[0029]
Here, the partition wall 4 and the partition wall 9 of the accessory case have a double structure, and have a heat insulating effect. In some cases, a heat insulating material may be provided in the partition 4 and the partition 9 of the accessory case. The partition 4 may be formed integrally with the case 3, and the partition 9 of the small case may be formed integrally with the small case 8.
