The cool air having flowed through the vegetable compartment 12 flows from the suction port 43 into the return duct 44 and returns to the refrigeration cooler room 32. The cold air returned to the refrigerator cooler chamber 32 exchanges heat with the refrigerator cooler 30 and is cooled again.

冷凍冷却器３４は、冷凍冷却器室３６の空気を冷却して、例えば、−２０〜−３０℃の冷気を生成する。生成した冷気は、冷凍ファン３５の回転によってダクト３７を介して製氷室、第１冷凍室１６及び第２冷凍室１７に供給されこれらの貯蔵室を冷却する。製氷室及び第１冷凍室１６を冷却した空気は、不図示の透孔を通って第２冷凍室１７へ流れ込み、第２冷凍室１７に供給された冷気と合流し、その後、第２冷凍室１７の背面に設けられた吸込口４５からリターンダクト４６を通って冷凍冷却器室３６に戻り、冷凍冷却器３４と熱交換して再び冷却される。   The refrigerator-cooler 34 cools the air of the refrigerator-cooler room 36, and produces cold air of, for example, -20 to -30.degree. The generated cold air is supplied to the ice making chamber, the first freezing chamber 16 and the second freezing chamber 17 through the duct 37 by the rotation of the freezing fan 35 and cools these storage chambers. The air that has cooled the ice making chamber and the first freezing chamber 16 flows into the second freezing chamber 17 through a through hole (not shown), merges with the cold air supplied to the second freezing chamber 17, and then the second freezing chamber It returns from the suction port 45 provided on the back surface 17 through the return duct 46 to the refrigeration cooler chamber 36, exchanges heat with the refrigeration cooler 34, and is cooled again.

このような構成の冷蔵庫１では、内部に調整空間Ｓ３を形成する調整容器５５が野菜室１２内に設けられている。図２に示すように、調整容器５５の前面には、下段後容器８０の後方壁８０ａに設けられた開口部８０ｂと前後に対向するように開口部５５ａが穿設され、開口部５５ａの外側を取り囲むようにゴム又はシリコーン等のゴム状弾性体からなるシール材６６が設けられている。   In the refrigerator 1 having such a configuration, the adjustment container 55 forming the adjustment space S3 inside is provided in the vegetable compartment 12. As shown in FIG. 2, an opening 55a is bored in the front of the adjustment container 55 so as to face the opening 80b provided in the rear wall 80a of the lower rear container 80 in the front-rear direction. And a sealing material 66 made of a rubber-like elastic material such as rubber or silicone.

貯蔵容器７０を野菜室１２内に収納すると、シール材６６が開口部８０ｂを取り囲むように下段後容器８０の後方壁８０ａに当接する。これにより、下段後容器８０の開口部８０ｂと調整容器５５の開口部５５ａとがシール材６６によって接続され、貯蔵空間Ｓ１の下部（貯蔵空間Ｓ１の高さ方向中央部より下側）において調整空間Ｓ３と連通する。つまり、本実施形態では、開口部８０ｂと開口部５５ａとシール材６６の内側が、貯蔵空間Ｓ１と調整空間Ｓ３とを連通する連通部５３を構成する。   When the storage container 70 is stored in the vegetable compartment 12, the seal material 66 abuts on the rear wall 80a of the lower rear container 80 so as to surround the opening 80b. Thus, the opening 80b of the lower rear container 80 and the opening 55a of the adjustment container 55 are connected by the sealing material 66, and the adjustment space is below the storage space S1 (lower than the central portion of the storage space S1). It communicates with S3. That is, in the present embodiment, the opening 80b, the opening 55a, and the inner side of the seal material 66 constitute the communication portion 53 communicating the storage space S1 with the adjustment space S3.

調整空間Ｓ３には、調整空間Ｓ３の酸素濃度を低減する酸素分離モジュール６０と、調整空間Ｓ３の空気をかき混ぜる撹拌ファン５６とが設けられている。   In the adjustment space S3, an oxygen separation module 60 for reducing the oxygen concentration in the adjustment space S3 and a stirring fan 56 for mixing the air in the adjustment space S3 are provided.

酸素分離モジュール６０は、箱形のケース６１に設けられた酸素分離膜６２を備える。酸素分離膜６２は、一方面が調整空間Ｓ３の空気と接触し、他方面がケース６１内部の空気と接触するように、調整空間Ｓ３とケース６１内部とを仕切っている。酸素分離膜６２は、その両側に圧力差が生じると高圧側の空気中の酸素が膜内部を拡散移動して低圧側の表面から離脱することで、低圧側の酸素濃度を低下させる。   The oxygen separation module 60 includes an oxygen separation membrane 62 provided in a box-shaped case 61. The oxygen separation membrane 62 divides the adjustment space S3 from the inside of the case 61 so that one surface is in contact with the air in the adjustment space S3 and the other surface is in contact with the air inside the case 61. When a pressure difference occurs on both sides of the oxygen separation membrane 62, oxygen in air on the high pressure side diffuses and moves inside the membrane to separate from the surface on the low pressure side, thereby reducing the oxygen concentration on the low pressure side.

なお、本実施形態では、下段後容器８０の後方壁８０ａの後方に間隔を開け、後方壁８０ａとほぼ平行に酸素分離モジュール６０を設けたが、調整空間Ｓ３の任意の位置に酸素分離モジュール６０を設けることができる。   In the present embodiment, the oxygen separation module 60 is provided at the rear of the rear wall 80a of the lower-stage rear container 80 and substantially parallel to the rear wall 80a. However, the oxygen separation module 60 is provided at any position in the adjustment space S3. Can be provided.

ケース６１の内部は、キャビネット２の背面下部に設けられた機械室３８に配置された排気ポンプ６３と排気ホース６４によって接続され、排気ポンプ６３の動作によってケース６１内部の空気を吸引して、機械室３８からキャビネット２の外部へ排気する（図１参照）。   The inside of the case 61 is connected by an exhaust pump 63 and an exhaust hose 64 arranged in a machine room 38 provided at the lower rear of the cabinet 2 and suctions air inside the case 61 by the operation of the exhaust pump 63 The chamber 38 is evacuated to the outside of the cabinet 2 (see FIG. 1).

なお、排気ポンプ６３は防音材で覆われて機械室３８に設けられることが好ましい。これにより排気ポンプ６３の動作音による騒音を抑えることができる。   The exhaust pump 63 is preferably covered with a soundproof material and provided in the machine room 38. Thereby, noise due to the operation noise of the exhaust pump 63 can be suppressed.

酸素分離膜６２を透過した酸素を機械室３８へ排気する排気ホース６４は、キャビネット２の背面壁に設けられた野菜室１２と機械室３８とを連通する挿通孔２ｂに挿通され、野菜室１２に設けられた酸素分離モジュール６０から機械室３８へ引き出されている。なお、図１に例示するように、排水ホース２８を挿通する挿通孔２ａと排気ホース６４を挿通する挿通孔２ｂとが途中で合わさって１つの挿通孔になってもよい。   The exhaust hose 64 for exhausting the oxygen that has permeated the oxygen separation membrane 62 to the machine room 38 is inserted into the insertion hole 2 b connecting the vegetable room 12 provided on the back wall of the cabinet 2 and the machine room 38. From the oxygen separation module 60 provided to the machine room 38. In addition, as illustrated in FIG. 1, the insertion hole 2 a for inserting the drainage hose 28 and the insertion hole 2 b for inserting the exhaust hose 64 may be combined halfway to form one insertion hole.

撹拌ファン５６は、調整空間Ｓ３内の空気を撹拌して、酸素分離膜６２に接触する調整空間Ｓ３内の空気を移動させる。撹拌ファン５６は、その吹出口５６ａが貯蔵空間Ｓ１と調整空間Ｓ３とを連通する連通部５３と対向しないように設けられることが好ましく、より好ましくは、吹出口５６ａが酸素分離モジュール６０の酸素分離膜６２に対向するように調整空間Ｓ３に設けられることがより好ましい。   The agitation fan 56 agitates the air in the adjustment space S 3 to move the air in the adjustment space S 3 in contact with the oxygen separation membrane 62. The stirring fan 56 is preferably provided so that the outlet 56a does not face the communication portion 53 that connects the storage space S1 and the adjustment space S3. More preferably, the outlet 56a is an oxygen separation module of the oxygen separation module 60 More preferably, it is provided in the adjustment space S3 so as to face the membrane 62.

また、下段後容器８０の後方壁８０ａには、後方壁８０ａとの間に隙間５２ａをあけつつ開口部８０ｂを覆うように配置された板状の風制限部５２が設けられている。調整空間Ｓ３から連通部５３を通過した風は、風制限部５２に衝突して貯蔵空間Ｓ１への直接的な進入が抑制される。つまり、風制限部５２は、連通部５３における風の流れを制限しつつ、貯蔵空間Ｓ１と調整空間Ｓ３との間で空気の流通を可能とする。   In addition, a plate-like wind restricting portion 52 is provided on the rear wall 80a of the lower rear container 80 so as to cover the opening 80b with a gap 52a between the rear wall 80a and the rear wall 80a. The wind which has passed through the communication part 53 from the adjustment space S3 collides with the wind restriction part 52, and the direct approach to the storage space S1 is suppressed. That is, the wind restricting portion 52 enables the flow of air between the storage space S1 and the adjustment space S3 while restricting the flow of the wind in the communication portion 53.

キャビネット２の背面上部には、冷蔵庫１の動作全般を制御する制御部５０が設けられている（図１参照）。制御部５０は、冷蔵温度センサ２５、冷凍温度センサ２６、扉センサ２９などの各種センサ等から入力される信号や、ＥＥＰＲＯＭ等の不揮発性記録媒体からなるメモリに記憶された制御プログラムに基づいて、冷蔵ファン３１、冷凍ファン３５、圧縮機３９、冷凍サイクルに設けられた切替弁（不図示）、排気ポンプ６３などの各種電気部品を制御することで、各室を所定温度に冷却したり、野菜室１２に設けた上段容器７２及び下段後容器８０の内部の酸素濃度を低減する。   A control unit 50 that controls the overall operation of the refrigerator 1 is provided on the upper rear surface of the cabinet 2 (see FIG. 1). The control unit 50 is based on signals input from various sensors such as the refrigerated temperature sensor 25, the frozen temperature sensor 26, and the door sensor 29, and a control program stored in a memory composed of a non-volatile recording medium such as EEPROM. Each chamber can be cooled to a predetermined temperature by controlling various electric parts such as a refrigeration fan 31, a freezing fan 35, a compressor 39, a switching valve (not shown) provided in a freezing cycle, an exhaust pump 63, and vegetables The oxygen concentration in the upper container 72 and the lower rear container 80 provided in the chamber 12 is reduced.

具体的には、冷蔵温度帯の冷蔵室１０及び野菜室１２を冷却する場合には、制御部５０が、冷凍サイクルに設けられた切替弁を切り替えて冷蔵冷却器３０に冷媒が流れるようにするとともに、冷蔵ファン３１を運転させる冷蔵冷却運転を実行する。これにより、冷蔵冷却器３０で冷却された空気は冷蔵室１０及び野菜室１２に送風され、冷蔵室１０の背面に設けられた冷蔵温度センサ２５の検出温度が所定温度範囲に収まるように冷蔵室１０及び野菜室１２を冷却する。   Specifically, when cooling the refrigerator compartment 10 and the vegetable compartment 12 in the refrigerator temperature zone, the control unit 50 switches the switching valve provided in the refrigeration cycle so that the refrigerant flows to the refrigerator cooler 30 At the same time, the refrigeration cooling operation for operating the refrigeration fan 31 is executed. Thereby, the air cooled by the refrigerator cooler 30 is blown to the refrigerator compartment 10 and the vegetable compartment 12 so that the detection temperature of the refrigerator temperature sensor 25 provided on the back of the refrigerator compartment 10 falls within the predetermined temperature range 10 and the vegetable room 12 are cooled.

製氷室、第１冷凍室１６、及び第２冷凍室１７を冷却する場合には、制御部５０が、冷凍サイクルに設けられた切替弁４７を切り替えて冷媒が冷凍冷却器３４に流れるようにするとともに、冷凍ファン３５を運転させる冷凍冷却運転を実行する。これにより、冷凍冷却器３４で冷却された空気は製氷室、第１冷凍室１６、及び第２冷凍室１７に送風され、第２冷凍室１７の背面に設けられた冷凍温度センサ２６の検出温度が所定温度範囲に収まるように製氷室、第１冷凍室１６、及び第２冷凍室１７を冷却する。   When cooling the ice making chamber, the first freezing chamber 16, and the second freezing chamber 17, the control unit 50 switches the switching valve 47 provided in the refrigeration cycle so that the refrigerant flows to the refrigeration cooler 34 At the same time, the refrigeration cooling operation for operating the refrigeration fan 35 is executed. Thus, the air cooled by the refrigeration cooler 34 is blown to the ice making chamber, the first freezing chamber 16 and the second freezing chamber 17, and the detected temperature of the freezing temperature sensor 26 provided on the back of the second freezing chamber 17 Cool the ice making chamber, the first freezing chamber 16 and the second freezing chamber 17 so that the temperature of

上段容器７２及び下段後容器８０の内部の酸素濃度を低減する減酸素運転を実行するには、扉センサ２９によって野菜室扉１３が閉扉状態にあることを検出している時に、調整空間Ｓ３に設けられた撹拌ファン５６を回転させつつ、機械室３８に設けられた排気ポンプ６３を動作させる。これにより、酸素分離モジュール６０は、ケース６１内部が酸素分離膜６２を挟んで対向する調整空間Ｓ３より低圧になるため、調整空間Ｓ３の酸素が酸素分離膜６２を透過して排気ホース６４を介してキャビネット２の外部へ排気され、調整空間Ｓ３の酸素濃度が低下する。   In order to execute the oxygen reduction operation to reduce the oxygen concentration inside the upper container 72 and the lower rear container 80, it is detected in the adjustment space S3 that the door sensor 29 detects that the vegetable compartment door 13 is in the closed state. The exhaust pump 63 provided in the machine room 38 is operated while rotating the stirring fan 56 provided. As a result, since the oxygen separation module 60 has a lower pressure than the adjustment space S3 in which the inside of the case 61 opposes with the oxygen separation membrane 62 interposed therebetween, oxygen in the adjustment space S3 permeates the oxygen separation membrane 62 and passes through the exhaust hose 64 As a result, the air is exhausted to the outside of the cabinet 2, and the oxygen concentration in the adjustment space S3 decreases.

野菜室扉１３の閉扉状態では、調整空間Ｓ３が貯蔵空間Ｓ１と連通しているため、排気ポンプ６３の動作によって調整空間Ｓ３の酸素濃度が低下して貯蔵空間Ｓ１と調整空間Ｓ３との間で酸素濃度差が生じると、貯蔵空間Ｓ１の酸素が調整空間Ｓ３へ拡散し、その結果、通気孔７７を介して貯蔵空間Ｓ１に連通する貯蔵空間Ｓ２の酸素濃度が低下する。   Since the adjustment space S3 communicates with the storage space S1 in the closed state of the vegetable compartment door 13, the oxygen concentration in the adjustment space S3 is reduced by the operation of the exhaust pump 63, and between the storage space S1 and the adjustment space S3. When the oxygen concentration difference occurs, the oxygen in the storage space S1 diffuses to the adjustment space S3. As a result, the oxygen concentration in the storage space S2 communicated with the storage space S1 via the air vent 77 decreases.

また、調整空間Ｓ３の空気が酸素分離膜６２の近傍で滞留すると、調整空間Ｓ３の酸素がケース６１側へ移動しにくくなるが、本実施形態では、排気ポンプ６３の動作とともに撹拌ファン５６も回転するため、酸素分離膜６２に接触する調整空間Ｓ３の空気を移動させることができ、調整空間Ｓ３の酸素を酸素分離モジュール６０によって効率よく排出することができる。   In addition, when the air in the adjustment space S3 stays in the vicinity of the oxygen separation membrane 62, the oxygen in the adjustment space S3 becomes difficult to move to the case 61 side, but in the present embodiment, the stirring fan 56 also rotates with the operation of the exhaust pump 63. Therefore, the air in the adjustment space S3 in contact with the oxygen separation membrane 62 can be moved, and the oxygen in the adjustment space S3 can be efficiently discharged by the oxygen separation module 60.

その際、本実施形態では、連通部５３における風の流れを制限する風制限部５２が設けられているため、撹拌ファン５６によって調整空間Ｓ３の空気を撹拌しても、調整空間Ｓ３の空気が連通部５３から貯蔵空間Ｓ１へ吹き出にくくなる。そのため、貯蔵空間Ｓ１に収容された貯蔵品に直接当たる風量を抑えることができ、当該貯蔵品の乾燥を抑えることができる。   At this time, in the present embodiment, since the wind restricting portion 52 for restricting the flow of the air in the communication portion 53 is provided, the air in the adjustment space S3 is obtained even when the air in the adjustment space S3 is stirred by the stirring fan 56. It becomes difficult to blow out from the communication part 53 to the storage space S1. Therefore, it is possible to suppress the amount of air that directly hits the stored product stored in the storage space S1, and to suppress the drying of the stored product.

また、撹拌ファン５６の吹出口５６ａを連通部５３と対向しないように配置することで、撹拌ファン５６から吹き出した風が連通部５３を通って貯蔵空間Ｓ１へ勢いよく吹き出すことがなくなり、より一層、貯蔵空間Ｓ１に収容された貯蔵品の乾燥を抑えることができる。   Further, by arranging the outlet 56a of the stirring fan 56 so as not to face the communication portion 53, the wind blown from the stirring fan 56 does not vigorously blow out to the storage space S1 through the communication portion 53. The drying of the stored products accommodated in the storage space S1 can be suppressed.

また、撹拌ファン５６の吹出口５６ａを酸素分離モジュール６０の酸素分離膜６２に対向して配置し、酸素分離膜６２に対して略垂直な方向から風を当てる場合であると、撹拌ファン５６から吹き出した風を整流しなくても酸素分離膜６２に接触する調整空間Ｓ３の空気を素早く移動させることができる。そのため、撹拌ファン５６を酸素分離モジュール６０に近接させて配置させることができ、調整容器５５を小さく設けることができる。   Further, when the blowout port 56a of the stirring fan 56 is disposed to face the oxygen separation membrane 62 of the oxygen separation module 60 and air is applied from a direction substantially perpendicular to the oxygen separation membrane 62, the stirring fan 56 Even if the blown-out wind is not rectified, the air in the adjustment space S3 in contact with the oxygen separation membrane 62 can be moved quickly. Therefore, the stirring fan 56 can be disposed close to the oxygen separation module 60, and the adjustment container 55 can be provided small.

また、本実施形態では、貯蔵空間Ｓ１の下部に連通部５３を介して調整空間Ｓ３が接続されており、酸素濃度が低下し比重が軽くなった空気が、調整空間Ｓ３から連通部５３を介して貯蔵空間Ｓ１の下部へ導入されるため、貯蔵空間Ｓ１において当該空気が自然対流しやすくなり、貯蔵空間Ｓ１内の酸素濃度を速やかに低下させることができる。   Further, in the present embodiment, the adjustment space S3 is connected to the lower part of the storage space S1 via the communication part 53, and the air whose oxygen concentration is reduced and the specific gravity is reduced is from the adjustment space S3 via the communication part 53. Since the air is introduced to the lower part of the storage space S1, the air is easily convected naturally in the storage space S1, and the oxygen concentration in the storage space S1 can be rapidly reduced.

（第２実施形態）
第２実施形態について、図３を参照して説明する。なお、第１実施形態と同一の構成のものについては同一の符号を付し、その構成の説明を省略する。 Second Embodiment
The second embodiment will be described with reference to FIG. The same components as those of the first embodiment are denoted by the same reference numerals, and the description of the components will be omitted.

上記した第１実施形態では、風制限部５２として、下段後容器８０の後方壁８０ａとの間に隙間５２ａをあけつつ開口部８０ｂを覆うように板状の部材を設ける場合について説明したが、本実施形態では、調整容器５５の開口部５５ａを開閉することで連通部５３における風の流れの遮断と開放とを切り替えるシャッタ１５２を風制限部として備える。   In the first embodiment described above, the case where the plate-like member is provided so as to cover the opening 80b while opening the gap 52a between the lower end rear container 80 and the rear wall 80a of the lower rear container 80 has been described. In the present embodiment, a shutter 152 that switches between blocking and opening the flow of air in the communication unit 53 by opening and closing the opening 55 a of the adjustment container 55 is provided as a wind restriction unit.

本実施形態では、図３に示すように、減酸素運転の実行時にシャッタ１５２による調整容器５５の開口部５５ａの開放量を小さくすることで、撹拌ファン５６によって調整空間Ｓ３の空気を撹拌しても、調整空間Ｓ３の空気が連通部５３から貯蔵空間Ｓ１へ吹き出にくくなる。そのため、連通部５３を介して貯蔵空間Ｓ１と調整空間Ｓ３との間で空気の流通を可能としつつ、貯蔵空間Ｓ１に収容された貯蔵品に直接当たる風量を抑えることができ、当該貯蔵品の乾燥を抑えることができる。   In the present embodiment, as shown in FIG. 3, the air in the adjustment space S3 is agitated by the agitation fan 56 by reducing the opening amount of the opening 55a of the adjustment container 55 by the shutter 152 at the time of execution of the oxygen reduction operation. Also, the air in the adjustment space S3 is less likely to blow out from the communication portion 53 to the storage space S1. Therefore, air flow can be made between the storage space S1 and the adjustment space S3 via the communication portion 53, and the volume of air directly impinging on the stored product stored in the storage space S1 can be suppressed. Drying can be suppressed.

また、野菜室扉１３の開扉時には、図３において二点鎖線で示すように、シャッタ１５２によって調整容器５５の開口部５５ａを閉じて調整空間Ｓ３を閉塞した空間とすることができ、野菜室扉１３が閉扉された後に速やかに貯蔵空間Ｓ１の酸素濃度を低下させることができる。   Further, when the vegetable compartment door 13 is opened, as shown by a two-dot chain line in FIG. 3, the opening part 55a of the adjustment container 55 can be closed by the shutter 152 to make the space closed the adjustment space S3. The oxygen concentration in the storage space S1 can be reduced promptly after the door 13 is closed.

なお、その他の構成及び作用効果は上記した第１実施形態と同様であり、詳細な説明は省略する。   In addition, the other structure and the effect are the same as that of above-mentioned 1st Embodiment, and detailed description is abbreviate | omitted.

（第３実施形態）
第３実施形態について、図４を参照して説明する。なお、第１実施形態と同一の構成のものについては同一の符号を付し、その構成の説明を省略する。 Third Embodiment
The third embodiment will be described with reference to FIG. The same components as those of the first embodiment are denoted by the same reference numerals, and the description of the components will be omitted.

上記した第１実施形態では、風制限部５２として、下段後容器８０の後方壁８０ａとの間に隙間５２ａをあけつつ開口部８０ｂを覆うように板状の部材を設ける場合について説明したが、本実施形態では、調整容器５５の開口部５５ａを塞ぐように設けた気体透過シート２５２を風制限部として備える。   In the first embodiment described above, the case where the plate-like member is provided so as to cover the opening 80b while opening the gap 52a between the lower end rear container 80 and the rear wall 80a of the lower rear container 80 has been described. In the present embodiment, a gas-permeable sheet 252 provided to close the opening 55 a of the adjustment container 55 is provided as a wind restriction part.

気体透過シート２５２は、防水性及び透湿性を有するシート材、例えば、直径が０．５μｍ〜３μｍの孔を多数有する多孔質シート材であり、水蒸気粒子や酸素分子を通過させるが、孔よりも大きな水の粒子を遮断する。また、気体透過シート２５２は、多孔質状であることから、撹拌ファン５６の回転によって発生する空気（風）の流通をある程度許容しつつ、調整空間Ｓ３の空気が貯蔵空間Ｓ１へ進入するのを抑制する。一例を挙げると、ポリエステル長繊維不織布とポリエチレン多孔質フィルムをラミネートした透湿防水シートなどを気体透過シート２５２に用いることができる。   The gas-permeable sheet 252 is a waterproof and moisture-permeable sheet material, for example, a porous sheet material having a large number of holes with a diameter of 0.5 μm to 3 μm, and allows water vapor particles and oxygen molecules to pass therethrough. Block large water particles. Further, since the gas permeable sheet 252 is porous, air in the adjustment space S3 enters the storage space S1 while allowing the circulation of air (wind) generated by the rotation of the stirring fan 56 to some extent. Suppress. As an example, a moisture-permeable waterproof sheet in which a polyester long-fiber non-woven fabric and a polyethylene porous film are laminated can be used as the gas-permeable sheet 252.

本実施形態では、調整容器５５の開口部５５ａを塞ぐように設けられた気体透過シート２５２が空気の流通を抑制するため、撹拌ファン５６によって調整空間Ｓ３の空気を撹拌しても連通部５３における風の流れが弱められ、調整空間Ｓ３の空気が貯蔵空間Ｓ１へ吹き出にくくなり、貯蔵空間Ｓ１に収容された貯蔵品の乾燥を抑えつつ、貯蔵空間Ｓ１の酸素濃度を低下させることができる。   In the present embodiment, the gas permeable sheet 252 provided so as to close the opening 55 a of the adjustment container 55 suppresses the flow of air, so even if the air of the adjustment space S3 is agitated by the agitation fan 56 The flow of wind is weakened, air in the adjustment space S3 is less likely to blow out to the storage space S1, and the concentration of oxygen in the storage space S1 can be reduced while suppressing the drying of the stored products accommodated in the storage space S1.

なお、気体透過シート２５２は、上記のように風の流れを弱めて調整空間Ｓ３の空気を貯蔵空間Ｓ１へ供給してもよく、また、連通部５３における風の流れを遮断し、貯蔵空間Ｓ１と調整空間Ｓ３との間の酸素濃度差によって生じる拡散で調整空間Ｓ３の空気を貯蔵空間Ｓ１へ供給してもよい。   As described above, the gas permeable sheet 252 may weaken the flow of wind and supply the air of the adjustment space S3 to the storage space S1, and also block the flow of wind in the communication portion 53, thereby reducing the flow of the storage space S1. The air of the adjustment space S3 may be supplied to the storage space S1 by diffusion caused by the oxygen concentration difference between the space S1 and the adjustment space S3.

その他の構成及び作用効果は上記した第１実施形態と同様であり、詳細な説明は省略する。   Other configurations and operational effects are the same as those of the first embodiment described above, and the detailed description will be omitted.

（第４実施形態）
第４実施形態について、図５を参照して説明する。なお、第１実施形態と同一の構成のものについては同一の符号を付し、その構成の説明を省略する。 Fourth Embodiment
The fourth embodiment will be described with reference to FIG. The same components as those of the first embodiment are denoted by the same reference numerals, and the description of the components will be omitted.

上記した第１実施形態では、風制限部５２として、下段後容器８０の後方壁８０ａとの間に隙間５２ａをあけつつ開口部８０ｂを覆うように板状の部材を設ける場合について説明したが、本実施形態では、調整容器５５の開口部５５ａを塞ぐように設けたルーバー３５２を風制限部として備える。   In the first embodiment described above, the case where the plate-like member is provided so as to cover the opening 80b while opening the gap 52a between the lower end rear container 80 and the rear wall 80a of the lower rear container 80 has been described. In the present embodiment, a louver 352 provided so as to close the opening 55 a of the adjustment container 55 is provided as a wind restriction part.

本実施形態では、調整容器５５の開口部５５ａを塞ぐように設けられたルーバー３５２が、空気の流通を抑制するため、撹拌ファン５６によって調整空間Ｓ３の空気を撹拌しても連通部５３における風の流れが弱められ、調整空間Ｓ３の空気が貯蔵空間Ｓ１へ吹き出にくくなる。そのため、本実施形態でも貯蔵空間Ｓ１に収容された貯蔵品の乾燥を抑えつつ、貯蔵空間Ｓ１の酸素濃度を低下させることができる。   In the present embodiment, the louver 352 provided so as to close the opening 55 a of the adjustment container 55 suppresses the flow of air, so even if the stirring fan 56 stirs the air in the adjustment space S 3 The air flow in the adjustment space S3 is less likely to blow out to the storage space S1. Therefore, also in the present embodiment, it is possible to reduce the oxygen concentration in the storage space S1 while suppressing the drying of the stored products accommodated in the storage space S1.

なお、その他の構成及び作用効果は上記した第１実施形態と同様であり、詳細な説明は省略する。   In addition, the other structure and the effect are the same as that of above-mentioned 1st Embodiment, and detailed description is abbreviate | omitted.

（その他の実施形態）
第１実施形態では、貯蔵空間Ｓ１を形成する下段後容器８０の後方壁８０ａに風制限部５２を設ける場合について説明したが、調整容器５５の開口部５５ａから後方へ隙間をあけつつ調整容器５５の開口部５５ａを覆うように、調整空間Ｓ３を形成する調整容器５５に板状の風制限部を設けてもよい。 (Other embodiments)
In the first embodiment, the case where the wind restriction portion 52 is provided on the rear wall 80a of the lower rear container 80 forming the storage space S1 has been described, but the adjustment container 55 is opened while leaving a gap rearward from the opening 55a of the adjustment container 55. A plate-like wind restriction may be provided in the adjustment container 55 forming the adjustment space S3 so as to cover the opening 55a.
