Description

冰箱 Refrigerator

本發明係關於在區隔貯藏室的各壁部配置真空隔熱材的冰箱。 The present invention relates to a refrigerator in which vacuum insulation materials are arranged on each wall of a partitioned storage room.

在過去的冰箱中，從上方起依序配置冷藏室、製冰室、冷凍室、蔬菜室。在此配置的情況下，在冰箱的最低位置配置蔬菜室。因此，使用者為了要從蔬菜室取出蔬菜，必須要屈膝蹲下或彎腰。 In the refrigerator of the past, the refrigerator compartment, the ice-making compartment, the freezing compartment, and the vegetable compartment are arranged in order from the top. In the case of this arrangement, the vegetable compartment is arranged at the lowest position of the refrigerator. Therefore, in order to remove the vegetables from the vegetable room, the user must kneel down or bend down.

在此，比較蔬菜室和冷凍室中的門片的開關次數或者門片的開時間的情況下，雖然有個別差異，但大致上是蔬菜室的門片之開關次數為多，門片的開時間也長。因此，將蔬菜室和冷凍室的位置交換，將蔬菜室配置在較冷凍室上方，預期可以提高冰箱整體的便利性。 Here, when comparing the number of openings and opening times of the doors in the vegetable room and the freezer, although there are individual differences, the number of openings and openings of the doors in the vegetable room is generally high. The time is also long. Therefore, it is expected that the convenience of the refrigerator as a whole can be improved by swapping the positions of the vegetable compartment and the freezing compartment and arranging the vegetable compartment above the freezing compartment.

但是，首先為了提高熱效率，過去的冰箱構成為，將冷凍溫度帶的複數個室集合為1處。 However, first, in order to improve thermal efficiency, the refrigerator in the past is configured to collect a plurality of compartments in a freezing temperature zone into one place.

再者，過去的冰箱構成為，將冷卻器配置在冷凍室的背面，在冷凍室和冷卻器之間即使不設置特別的隔熱構件，也不容易發生結露或結霜等的不良狀況。 In addition, the refrigerator in the past is configured such that the cooler is arranged on the back of the freezer compartment, and even if a special heat insulating member is not provided between the freezer compartment and the cooler, defects such as dew condensation or frost are unlikely to occur.

相對於此，為了提高使用者的便利性，考慮將冰箱配置為從上方起依序為冷藏室、製冰室、蔬菜室、冷凍室。此冰箱配置為，從上方起冷藏溫度帶(亦即正溫度帶)的貯藏室和冷凍溫度帶(亦即負溫度帶)的貯藏室互相交替。因此，首先，此種配置的冰箱的熱效率就比過去的冰箱差。另外，為了確保必要的隔熱性能，各室的壁部之厚度變大，在冰箱外形相同的情況下進行比較的話，則其能夠收納食品的空間變小。 On the other hand, in order to improve the user's convenience, it is considered to arrange the refrigerator in order from the top into a refrigerator compartment, an ice compartment, a vegetable compartment, and a freezer compartment. This refrigerator is configured such that the storage compartment of the refrigerating temperature zone (ie, positive temperature zone) and the storage compartment of the freezing temperature zone (ie, negative temperature zone) alternate from above. Therefore, first of all, the thermal efficiency of a refrigerator of this configuration is inferior to that of past refrigerators. In addition, in order to ensure the necessary heat insulation performance, the thickness of the wall of each room becomes larger, and when the refrigerator is compared with the same outer shape, the space for storing food becomes smaller.

另外，其次，此種配置的冰箱之冷卻器配置在蔬菜室的背面，相較於過去，其區隔蔬菜室和冷卻器的壁部必須具有較高的隔熱性能。為了提高隔熱性能，只要使壁部的厚度加大即可。但是，如前所述，就犧牲了食品收納空間。因此，過去係使用加工性良好、方便安裝及卸下、或者搬運的泡沫聚苯乙烯的成型品作為隔熱構件。但是，使用隔熱性能更高的真空隔熱材來作為隔熱構件，藉此兼顧隔熱性能及食品收納空間確保。所謂的隔熱性能高，係為熱傳遞係數小。 In addition, secondly, the cooler of this type of refrigerator is arranged on the back of the vegetable compartment. Compared with the past, the wall that separates the vegetable compartment and the cooler must have higher heat insulation performance. In order to improve the heat insulation performance, it is only necessary to increase the thickness of the wall portion. However, as mentioned earlier, food storage space is sacrificed. Therefore, in the past, molded products of Styrofoam with good processability, easy installation and removal, or transportation were used as heat insulating members. However, a vacuum heat insulating material with higher heat insulating performance is used as the heat insulating member, thereby taking into consideration the heat insulating performance and ensuring the food storage space. The so-called heat insulation performance is high, because the heat transfer coefficient is small.

專利文獻1：日本特開2012-242072號公報 Patent Literature 1: Japanese Patent Laid-Open No. 2012-242072

在蔬菜室和冷卻器之間配置真空隔熱材的情況下，必須要有用以將經由冷卻器冷卻後的空氣送入蔬菜室的風路。專利文獻1的請求項10中記載了「在構成內壁面的前述隔壁當中，於前述流入口及前述流出口以外的前面設置前述真空隔熱材」。有如上述般的，除了流入口和流出口以外都用真空隔熱材覆蓋的方法。但是，在此的情況下，必須在真空隔熱材上開孔、在真空隔熱材設置缺口、或者使用複數真空隔熱材。因此，製造成本增加。 When a vacuum insulation material is arranged between the vegetable compartment and the cooler, it is necessary to use an air path for sending the air cooled by the cooler into the vegetable compartment. Claim 10 of Patent Document 1 describes "the provision of the vacuum heat insulating material on the front surface other than the inflow port and the outflow port among the partition walls constituting the inner wall surface". As mentioned above, except the inflow port and the outflow port, the method is covered with a vacuum insulation material. However, in this case, it is necessary to make holes in the vacuum heat insulating material, provide a notch in the vacuum heat insulating material, or use a plurality of vacuum heat insulating materials. Therefore, the manufacturing cost increases.

另外，必須在有限的空間中形成風路，風路構成變得複雜。 In addition, the air path must be formed in a limited space, and the structure of the air path becomes complicated.

本發明係為了解決上述課題，其目的在於提供欲達成風路構成之簡便化的冰箱。 The present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a refrigerator for simplifying the configuration of an air passage.

本發明之冰箱，其包括：具有前面部及背面部的冷凍溫度帶之第1 貯藏室；具有前面部及背面部的冷凍溫度帶之第2貯藏室；具有前面部及背面部，且配置於前述第1貯藏室和前述第2貯藏室之間的冷藏溫度帶之第3貯藏室；設置於前述第2貯藏室的前述背面部側的冷卻器；設置在區隔包含前述前面部及前述背面部的前述第3貯藏室之各壁部的真空隔熱材；第1風路，形成於設置在前述第3貯藏室的前述背面部的前述真空隔熱材之後方，將空氣從前述冷卻器導入前述第2貯藏室；第2風路，形成於設置在前述第3貯藏室的前述背面部的前述真空隔熱材之後方，使得在前述第2貯藏室中已被利用過的空氣回到前述冷卻器；及第3風路，使得前述第3貯藏室中已被利用過的空氣透過回流口回到前述冷卻器；前述第1風路及前述第2風路，係形成為前後重疊，分別在前述真空隔熱材的寬幅方向分岔為二；流過前述第1風路的空氣，從較前述真空隔熱材的下端還要靠下方處吹出；流過前述第2風路的空氣，從較前述真空隔熱材的下端還要靠下方處導入；前述回流口，形成於前述真空隔熱材的下方。 The refrigerator of the present invention includes: a first storage room having a freezing temperature zone of a front part and a back part; a second storage room having a freezing temperature zone of a front part and a back part; and having a front part and a back part A third storage room in the refrigerating temperature zone between the first storage room and the second storage room; a cooler provided on the back side of the second storage room; and a partition including the front part and the back side A vacuum insulation material for each wall portion of the third storage room; a first air path is formed after the vacuum insulation material provided in the back surface portion of the third storage room, and takes air from the cooler Introduced into the second storage room; the second air path is formed after the vacuum heat insulating material provided on the back side of the third storage room to return the air that has been used in the second storage room The cooler; and the third air path, so that the used air in the third storage chamber returns to the cooler through the return port; the first air path and the second air path are formed to overlap front and back, Respectively branch into two in the width direction of the vacuum heat insulation material; the air flowing through the first air path is blown out below the lower end of the vacuum heat insulation material; the air flowing through the second air path Air is introduced from below the lower end of the vacuum insulation material; the return port is formed below the vacuum insulation material.

依據本發明的冰箱，第1風路及第2風路形成為前後重疊，分別在真空隔熱材的寬幅方向分岔為二，因此，無須使風路構成複雜化，而能夠達成風路構成的簡便化。 According to the refrigerator of the present invention, the first air path and the second air path are formed so as to overlap front and back, and each branch into two in the width direction of the vacuum insulation material. Therefore, the air path can be achieved without complicating the air path configuration Simplified composition.

Based on FIG. 3, the refrigerant circuit 70 and the air circulation path 80 of the refrigerator 1 will be briefly described. In addition, in FIG. 3, the refrigerant and the air flow are indicated by arrows. In addition, in FIG. 3, each storage room is illustrated for the explanation of the air circulation path 80. Furthermore, the refrigerant used in the refrigerant circuit 70 is not particularly limited.

說明冷媒回路70的構成。 The configuration of the refrigerant circuit 70 will be described.

冰箱1具有冷媒回路70。如圖3所示，壓縮機71、空冷凝縮器72、放熱管73、減壓裝置76、及冷卻器600藉由配管連接構成冷媒回路70。在放熱管73和減壓裝置76之間，連接了結露防止管74及乾燥機75。另外，在圖3中，以設置了將空氣供給至冷卻器600的送風機800的狀態為例進行圖示。 The refrigerator 1 has a refrigerant circuit 70. As shown in FIG. 3, the compressor 71, the air condenser 72, the heat release tube 73, the decompression device 76, and the cooler 600 are connected by piping to form a refrigerant circuit 70. Between the heat release tube 73 and the decompression device 76, a condensation prevention tube 74 and a dryer 75 are connected. In addition, in FIG. 3, the state which provided the blower 800 which supplies air to the cooler 600 is shown as an example.

說明冷媒回路70的作用。 The role of the refrigerant circuit 70 will be described.

壓縮機71驅動以將冷媒從壓縮機71送出。從壓縮機71送出的冷媒，流入形成於箱體50的機械室中設置的空冷凝縮器72。從空冷凝縮器72流出的冷媒流經設置在冰箱1的箱體50之聚氨基甲酸酯內部的放熱管73。然後，流經放熱管73的冷媒，流經環繞冰箱1的貯藏室的前面部50A之周圍的結露防止管74。冷媒藉由空冷凝縮器72、放熱管73、及結露防止管74的凝縮過程而凝縮。 The compressor 71 is driven to send the refrigerant from the compressor 71. The refrigerant sent from the compressor 71 flows into the empty condenser 72 provided in the machine room of the casing 50. The refrigerant flowing out of the empty condenser 72 flows through the heat release tube 73 provided inside the polyurethane of the cabinet 50 of the refrigerator 1. Then, the refrigerant flowing through the heat release tube 73 flows through the condensation prevention tube 74 surrounding the front portion 50A of the storage compartment of the refrigerator 1. The refrigerant is condensed by the condensation process of the empty condenser 72, the heat release tube 73, and the condensation prevention tube 74.

已凝縮的冷媒，經過乾燥機75之後，經過減壓裝置76，被供給至冷卻器600。冷卻器600，藉由供給至冷卻器600的冷媒蒸發，和由送風機800強 制內部循環的空氣進行熱交換，以產生冷氣。已產生的冷氣被供給至各貯藏室，將各貯藏室冷卻。之後，冷媒經過吸入管和減壓裝置76進行熱交換的同時溫度上升，回到壓縮機71。 The condensed refrigerant passes through the dryer 75, passes through the decompression device 76, and is supplied to the cooler 600. The cooler 600 evaporates the refrigerant supplied to the cooler 600 and exchanges heat with the air forcedly circulated by the blower 800 to generate cool air. The generated cold air is supplied to each storage room to cool each storage room. After that, the refrigerant passes through the suction pipe and the decompression device 76 to exchange heat while the temperature rises and returns to the compressor 71.

如上述，冰箱1具有冷媒回路70，產生冷卻各貯藏室的冷氣。 As described above, the refrigerator 1 has the refrigerant circuit 70 and generates cold air for cooling each storage compartment.

說明空氣循環路徑80的構成。 The structure of the air circulation path 80 will be described.

冰箱1具有空氣循環路徑80。空氣循環路徑80構成為包含吹出風路110及回流風路140。吹出風路110係為將冷氣導入各貯藏室者。另外，回流風路140係為將各貯藏室中利用於冷卻後的冷氣引導至冷卻器600者。亦即，空氣循環路徑80為，透過吹出風路110及回流風路140，使冷氣循環到冷卻器600及各貯藏室的路徑。 The refrigerator 1 has an air circulation path 80. The air circulation path 80 is configured to include the blowing air path 110 and the return air path 140. The blowing air passage 110 is for introducing cool air into each storage room. In addition, the return air path 140 is for guiding the cool air used for cooling in each storage room to the cooler 600. That is, the air circulation path 80 is a path through which the cold air is circulated to the cooler 600 and each storage room through the blowing air path 110 and the return air path 140.

在吹出風路110的入口設置風量調整裝置。冷藏室11的入口設置的風量調整裝置為第1氣閘101。製冰室21的入口設置的風量調整裝置為第2氣閘201a。溫度切換室22的入口設置的風量調整裝置為第3氣閘202。蔬菜室31的入口設置的風量調整裝置為第4氣閘301。 An air volume adjusting device is installed at the entrance of the blowout air path 110. The air volume adjusting device provided at the entrance of the refrigerator compartment 11 is the first air lock 101. The air volume adjusting device provided at the entrance of the ice making chamber 21 is the second air lock 201a. The air volume adjusting device provided at the entrance of the temperature switching chamber 22 is the third air lock 202. The air volume adjusting device provided at the entrance of the vegetable compartment 31 is the fourth air lock 301.

說明空氣循環路徑80的作用。 The function of the air circulation path 80 will be described.

送風機800驅動以將冰箱1的空氣供給至冷卻器600。然後，經由送風機800強制內部循環的空氣，在冷卻器600與冷媒進行熱交換而被冷卻。在冷卻器600中的熱交換所產生的冷氣，流經吹出風路110並被吹出到冰箱1內的各貯藏室中，將各貯藏室冷卻。 The blower 800 is driven to supply the air of the refrigerator 1 to the cooler 600. Then, the air forcedly circulated through the blower 800 exchanges heat with the refrigerant in the cooler 600 to be cooled. The cold air generated by the heat exchange in the cooler 600 flows through the blowing air path 110 and is blown out into the storage rooms in the refrigerator 1 to cool the storage rooms.

因應設置在各貯藏室的未圖示的溫度感測器所檢知的貯藏室內的空氣溫度或者貯藏食品的溫度，未圖示的控制裝置使各風量調整裝置動作，於各貯藏室和冷卻器600循環的空氣使各貯藏室保持在適當的溫度。在各貯藏室中利用於冷卻後的空氣，流經回流風路140後，回到冷卻器600。 In accordance with the temperature of the air in the storage room or the temperature of the stored food detected by the temperature sensor (not shown) installed in each storage room, the control device (not shown) operates each air volume adjustment device in each storage room and cooler 600 cycles of air keep each storage room at an appropriate temperature. The air used for cooling in each storage room flows through the return air path 140, and returns to the cooler 600.

第4回流口331，不重疊在1枚矩形之板狀的真空隔熱材500A1的前方投影面上，而是位於較此前方投影面靠下方外側。由第4吹出口321吹出的冷氣以後述方式循環：從位於蔬菜室31的下方中央部的第4回流口331排出，被導向冷卻器600，再次通過冷卻器600並且被冷卻。 The fourth return port 331 is not superimposed on the front projection surface of one rectangular plate-shaped vacuum heat insulating material 500A1, but is located below the front projection surface. The cold air blown out from the fourth air outlet 321 circulates in a manner described below: it is discharged from the fourth return port 331 located at the lower central portion of the vegetable compartment 31, is guided to the cooler 600, passes through the cooler 600 again, and is cooled.

說明冷凍室41的空氣之循環。 The circulation of air in the freezer compartment 41 will be described.

在冷卻器600產生的冷氣，流經第5吹出風路411，並分岔到左側第5吹出風路411A和右側第5吹出風路411B。分岔到左側第5吹出風路411A的冷氣透過第5吹出口421A被導入冷凍室41。分岔到右側第5吹出風路411B的冷氣透過第5吹出口421B被導入冷凍室41。在冷凍室41中已被利用過的冷氣，透過第5回流口431A及第5回流口431B從紙面下側向紙面上側流經左側第5回流風路412A及右側第5回流風路412B，透過第5接合部451A及第5接合部451B回到冷卻器600。 The cool air generated in the cooler 600 flows through the fifth blowing air path 411 and branches to the left fifth blowing air path 411A and the right fifth blowing air path 411B. The cold air branched to the left fifth blowing air path 411A is introduced into the freezer compartment 41 through the fifth blowing port 421A. The cold air branched to the right fifth blowing air path 411B is introduced into the freezer compartment 41 through the fifth blowing port 421B. The cold air that has been used in the freezer compartment 41 flows through the fifth backflow air path 412A and the right fifth backflow air path 412B from the lower side of the paper to the upper side of the paper surface through the fifth return port 431A and the fifth return port 431B, and passes through The fifth joint 451A and the fifth joint 451B return to the cooler 600.

繼之，說明真空隔熱材500A。 Next, the vacuum heat insulating material 500A will be described.

如圖2所示，冰箱1配置為由上方起依序為冷藏室11、製冰室21及溫度切換室22、蔬菜室31、冷凍室41。亦即、冰箱1配置為由上方起冷藏溫度帶的貯藏室和冷凍溫度帶的貯藏室彼此交替。 As shown in FIG. 2, the refrigerator 1 is arranged in order from the top of the refrigerator compartment 11, the ice making compartment 21 and the temperature switching compartment 22, the vegetable compartment 31, and the freezing compartment 41. That is, the refrigerator 1 is arranged such that the storage compartment of the refrigerating temperature zone and the storage compartment of the freezing temperature zone alternate from above.

冷藏室11的底面部(換言之，製冰室21及溫度切換室22的上面部)為作為壁部55之一的隔板51。蔬菜室31的上面部(換言之，製冰室21及溫度切換室22的底面部)為作為壁部55之一的隔板53。蔬菜室31的底面部及冷凍室41的上面部為作為壁部55之一的隔板54。而且，在各隔板的內部設置真空隔熱材500A以抑制熱移動。 The bottom part of the refrigerator compartment 11 (in other words, the upper parts of the ice making compartment 21 and the temperature switching compartment 22) is a partition 51 as one of the wall parts 55. The upper surface of the vegetable compartment 31 (in other words, the bottom surface of the ice making compartment 21 and the temperature switching compartment 22) is a partition 53 as one of the wall portions 55. The bottom surface portion of the vegetable compartment 31 and the upper surface portion of the freezing compartment 41 are partitions 54 as one of the wall portions 55. In addition, a vacuum heat insulating material 500A is provided inside each separator to suppress heat movement.

參照圖6，一邊說明配置在蔬菜室31的周圍的真空隔熱材500A。如上述，冰箱1中配置了包圍蔬菜室31的前後及上下的真空隔熱材500A。配置在冷卻器600的前面側(亦即蔬菜室31的背面側)的真空隔熱材500A稱之為真空隔熱材500A1。配置在蔬菜室31的上面側的真空隔熱材500A稱之為真空隔熱材500A2。配置在蔬菜室31的前面側的真空隔熱材500A稱之為真空隔熱材500A3。配置在蔬菜室31的底面側的真空隔熱材500A稱之為真空隔熱材500A4。 6, the vacuum heat insulating material 500A disposed around the vegetable compartment 31 will be described. As described above, the refrigerator 1 is provided with the vacuum heat insulating material 500A that surrounds the front, back, and top and bottom of the vegetable compartment 31. The vacuum heat insulating material 500A disposed on the front side of the cooler 600 (that is, the back side of the vegetable compartment 31) is referred to as a vacuum heat insulating material 500A1. The vacuum heat insulating material 500A disposed on the upper side of the vegetable compartment 31 is referred to as a vacuum heat insulating material 500A2. The vacuum heat insulating material 500A disposed on the front side of the vegetable compartment 31 is referred to as a vacuum heat insulating material 500A3. The vacuum heat insulating material 500A disposed on the bottom surface side of the vegetable compartment 31 is referred to as a vacuum heat insulating material 500A4.

在從側面觀看的狀態下，真空隔熱材500A1配置為長邊方向延伸於垂直方向，抑制蔬菜室31和箱體50的背面部50F側之間的熱移動。另外，真空隔熱材500A1構成為具有較冷卻器600的寬幅還要大的寬幅。 In a state viewed from the side, the vacuum heat insulating material 500A1 is arranged to extend in the longitudinal direction to the vertical direction, and to suppress heat movement between the vegetable compartment 31 and the back surface 50F side of the cabinet 50. In addition, the vacuum heat insulating material 500A1 is configured to have a wider width than that of the cooler 600.

真空隔熱材500A2設置於隔板53的內部，抑制蔬菜室31與製冰室21及溫度切換室22之間的熱移動。真空隔熱材500A2的後方端位於較蔬菜室31中收納的第2蔬菜室貯藏盒420B的上方開放端之後方端還要靠後方。藉此，抑制由於冷凍室41的吸熱使得第1蔬菜室貯藏盒420A變得低溫。 The vacuum heat insulating material 500A2 is provided inside the partition plate 53 to suppress heat movement between the vegetable compartment 31, the ice making compartment 21, and the temperature switching compartment 22. The rear end of the vacuum heat insulating material 500A2 is located behind the upper open end of the second vegetable compartment storage box 420B housed in the vegetable compartment 31. This suppresses the low temperature of the first vegetable compartment storage box 420A due to the heat absorption of the freezing compartment 41.

但是，雖然具備了真空隔熱材500A2，但很難用真空隔熱材500A2把蔬菜室31的寬幅及進深都全部覆蓋。因此，蔬菜室31的前後端部及左右端部的周圍，從冷凍溫度帶的貯藏室的吸熱量變多。另外，真空隔熱材500A2構成為， 用鋁等的金屬蒸鍍後的樹脂製之袋或者重疊了金屬箔的樹脂製之袋包住玻璃纖維等構成的芯材。一般來說，真空隔熱材500A為，在真空包裝後，留下作為袋之端部的邊緣，將其折疊設置。因此，真空隔熱材500A2產生金屬層的熱傳遞(亦即熱橋)，也由於此影響，相較於中央部的隔熱效果，真空隔熱材500A2的前後端部及左右端部之周圍的隔熱效果有較差的傾向。 However, although the vacuum heat insulating material 500A2 is provided, it is difficult to cover all the width and depth of the vegetable compartment 31 with the vacuum heat insulating material 500A2. Therefore, the amount of heat absorbed from the storage compartment in the freezing temperature zone around the front and rear end portions and the left and right end portions of the vegetable compartment 31 increases. Moreover, the vacuum heat insulating material 500A2 is comprised so that the core material which consists of glass fiber etc. may be wrapped with the resin bag which vapor-deposited metal, such as aluminum, or the resin bag which laminated the metal foil. Generally speaking, the vacuum heat insulating material 500A is such that after vacuum packaging, the edge which is the end of the bag is left and folded. Therefore, the vacuum heat insulating material 500A2 generates heat transfer of the metal layer (that is, thermal bridge), and due to this effect, compared with the heat insulation effect of the central portion, the front and rear ends and the left and right ends of the vacuum heat insulating material 500A2 The thermal insulation effect tends to be poor.

而且，在箱體50的背面部50F側設置風路構成零件時，將風路構成零件安裝在箱體50後再安裝內建真空隔熱材500A2的隔板53，則組裝比較容易。但是，在此情況下，必須將風路構成零件和隔板53接合，將隔板53和箱體50的左右側壁接合，有可能無法完全阻斷冷氣洩漏。 In addition, when the air path components are provided on the back surface 50F side of the case 50, the air path components are attached to the case 50, and then the partition plate 53 with the built-in vacuum heat insulating material 500A2 is installed, and the assembly is relatively easy. However, in this case, it is necessary to join the air path components and the partition plate 53 and the partition plate 53 and the left and right side walls of the case 50 may not be able to completely block the leakage of cold air.

因此，也預期到隔板53的前後左右端變得低溫，從蔬菜室31中貯藏的蔬菜蒸散的水分有可能會局部結露、或者有時會視程度而有結霜或結冰 Therefore, it is also expected that the front, back, left, and right ends of the partition plate 53 become low in temperature, and moisture evapotranspiration from the vegetables stored in the vegetable compartment 31 may locally dew, or may frost or freeze depending on the degree

因此，在冰箱1中，藉由設置蓋構造體430，盡量鎖住第1蔬菜室貯藏盒420A及第2蔬菜室貯藏盒420B中收納的蔬菜所蒸散的水分。另外，冰箱1中，藉由設置蓋構造體430，不只是鎖住水分，還可能將第1蔬菜室貯藏盒420A及第2蔬菜室貯藏盒420B的內部維持在高濕度。因此，依據冰箱1，能夠進一步抑制來自第1蔬菜室貯藏盒420A及第2蔬菜室貯藏盒420B中收納的蔬菜的蒸散，還能夠抑制對於隔板53等的結露或結霜等對於使用者不利之現象的發生。 Therefore, by providing the lid structure 430 in the refrigerator 1, the moisture evaporated by the vegetables stored in the first vegetable compartment storage box 420A and the second vegetable compartment storage box 420B is locked as much as possible. In addition, by providing the lid structure 430 in the refrigerator 1, not only the moisture is locked, but also the inside of the first vegetable compartment storage box 420A and the second vegetable compartment storage box 420B can be maintained at high humidity. Therefore, according to the refrigerator 1, it is possible to further suppress the evapotranspiration of the vegetables stored in the first vegetable compartment storage box 420A and the second vegetable compartment storage box 420B, and it is also possible to suppress dew condensation or frost on the partition plate 53 and the like, which is unfavorable to the user The occurrence of the phenomenon.

另外，風路構成零件中包含形成吹出風路110及回流風路140的備品及風量調整裝置。 In addition, the components of the air path include the spare parts and the air volume adjustment device that form the blowout air path 110 and the return air path 140.

真空隔熱材500A3設置在蔬菜室31的門片部31A之內部，抑制蔬菜室31和冰箱1的外部之間的熱移動。 The vacuum heat insulating material 500A3 is provided inside the door portion 31A of the vegetable compartment 31, and suppresses heat movement between the vegetable compartment 31 and the outside of the refrigerator 1.

真空隔熱材500A4設置於隔板53的內部，抑制蔬菜室31和冷凍室41之間的熱移動。真空隔熱材500A4的後方端，位於較蔬菜室31中收納的第1蔬菜室貯藏盒420A的底面的後方端後方長度D2之處。藉此，抑制因為製冰室21及溫度切換室 22的吸熱使得第1蔬菜室貯藏盒420A變得低溫。 The vacuum heat insulating material 500A4 is provided inside the partition plate 53 and suppresses heat movement between the vegetable compartment 31 and the freezing compartment 41. The rear end of the vacuum heat insulating material 500A4 is located a length D2 behind the rear end of the bottom surface of the first vegetable compartment storage box 420A housed in the vegetable compartment 31. This suppresses the low temperature of the first vegetable compartment storage box 420A due to the heat absorption of the ice making compartment 21 and the temperature switching compartment 22.

像這樣，在冰箱1中，於隔板53設置真空隔熱材500A2，於隔板54設置真空隔熱材500A4。藉此，抑制因為從位於蔬菜室31的上下的冷凍溫度帶的貯藏室的吸熱，使得蔬菜室31的第1蔬菜室貯藏盒420A及第2蔬菜室貯藏盒420B的內部變得低溫。 In this manner, in the refrigerator 1, the vacuum heat insulating material 500A2 is provided on the partition 53, and the vacuum heat insulating material 500A4 is provided on the partition 54. Thereby, it is suppressed that the inside of the first vegetable compartment storage box 420A and the second vegetable compartment storage box 420B of the vegetable compartment 31 becomes low in temperature due to the heat absorption from the storage compartment located above and below the vegetable compartment 31.

繼之，說明真空隔熱材500A1和空氣循環路徑80的一部分的關係。 Next, the relationship between the vacuum heat insulating material 500A1 and a part of the air circulation path 80 will be described.

真空隔熱材500A1設置於冷卻器600的前面側。另外，真空隔熱材500A1構成為具有較冷卻器600的寬幅還要大的寬幅。因此，藉由冰箱1可以獲致高隔熱效果。 The vacuum heat insulating material 500A1 is provided on the front side of the cooler 600. In addition, the vacuum heat insulating material 500A1 is configured to have a wider width than that of the cooler 600. Therefore, the refrigerator 1 can achieve a high thermal insulation effect.

而且，如圖5所示，在離開真空隔熱材500A的寬幅方向的冷卻器600的右側面形成第1回流風路141。冷卻器600的下面構成與蔬菜室31的壁部，其一部分具有第4回流風路312的功能。 Further, as shown in FIG. 5, the first return air path 141 is formed on the right side surface of the cooler 600 in the width direction away from the vacuum heat insulating material 500A. The lower surface of the cooler 600 forms a wall portion with the vegetable compartment 31, and a part of it has the function of the fourth return air path 312.

亦即，在冰箱1中，因為是在較真空隔熱材500A1的寬幅還要靠外側形成第1回流風路141，所以可以使用1枚矩形的板形狀構成的真空隔熱材500A1。若使用此種真空隔熱材500A1，不需要真空隔熱材500A1的角部之倒角及開孔、或者、不需要使真空隔熱材500A1為多數構成。因此，依據冰箱1，能夠抑制加工及製造成本的增加。因此，冰箱1組裝簡便而且製造效率佳。 That is, in the refrigerator 1, since the first return air path 141 is formed outside the wider width of the vacuum heat insulating material 500A1, a vacuum heat insulating material 500A1 composed of one rectangular plate shape can be used. If such a vacuum heat insulating material 500A1 is used, the chamfering and opening of the corner portion of the vacuum heat insulating material 500A1 are not required, or the vacuum heat insulating material 500A1 is not required to be a majority structure. Therefore, according to the refrigerator 1, an increase in processing and manufacturing costs can be suppressed. Therefore, the refrigerator 1 is easy to assemble and has good manufacturing efficiency.

如上述，真空隔熱材500A1係垂直配置，在真空隔熱材500A1的背面側形成冷卻器600。另外，在冰箱1中，使得第5吹出風路411及第5回流風路412分岔，在分岔之間形成第4回流口331。亦即，從正面觀看冰箱1的狀態下，第4回流口331位於左側第5吹出風路411A及左側第5回流風路412A、及右側第5吹出風路411B及右側第5回流風路412B之間。因此，藉由冰箱1，有效運用了蔬菜室31的背面部50F側的空間。 As described above, the vacuum heat insulating material 500A1 is vertically arranged, and the cooler 600 is formed on the back side of the vacuum heat insulating material 500A1. In addition, in the refrigerator 1, the fifth blowing air path 411 and the fifth return air path 412 are branched, and a fourth return port 331 is formed between the branches. That is, in a state where the refrigerator 1 is viewed from the front, the fourth return opening 331 is located on the left fifth blowout air path 411A and the left fifth return air path 412A, and the right fifth blowout air path 411B and the right fifth return air path 412B between. Therefore, with the refrigerator 1, the space on the back side 50F side of the vegetable compartment 31 is effectively used.

在一般的冰箱中，將蔬菜室的背面部50F側的真空隔熱材垂直配置，則在箱體的進深方向中的下端之位置和上端的位置為一致。因此，無法擴大蔬菜室的背面部50F側的上下的任一者的空間，另外在此空間中必須要形成風路，只能採用複雜的風路構成。 In a general refrigerator, when the vacuum heat insulating material on the rear surface portion 50F side of the vegetable compartment is vertically arranged, the position of the lower end and the position of the upper end in the depth direction of the cabinet are the same. Therefore, it is not possible to expand the space of any one of the upper and lower sides on the back surface portion 50F side of the vegetable compartment, and an air path must be formed in this space, and only a complicated air path can be used.

相對於此，冰箱1中，將真空隔熱材500A1垂直配置，同時使第5吹出風路411及第5回流風路412分岔，在分岔之間形成第4回流口331，藉此，無須使風路構成變得複雜，就能夠實現蔬菜室31之背面部50F側的空間之擴大。 On the other hand, in the refrigerator 1, the vacuum heat insulating material 500A1 is vertically arranged, and the fifth blowing air path 411 and the fifth return air path 412 are branched at the same time, and a fourth return opening 331 is formed between the branches, thereby, The space on the side of the rear surface 50F of the vegetable compartment 31 can be expanded without complicating the configuration of the air passage.

第4回流風路312及第5回流風路412，可以形成為使空氣從冷卻器600的下端流入，能夠使空氣向冷卻器600的前面前緣流入，並提高冷卻器600的熱交換效率。 The fourth return air path 312 and the fifth return air path 412 may be formed to allow air to flow in from the lower end of the cooler 600, to allow air to flow into the front front edge of the cooler 600, and to improve the heat exchange efficiency of the cooler 600.

<冰箱1發揮的效果> <effect of refrigerator 1>

如上述，冰箱1在真空隔熱材500A1的後方設置第5吹出風路411和第5回流風路412，第5吹出風路411及第5回流風路412形成為前後重疊，在真空隔熱材500A1的寬幅方向分岔為二。 As described above, the refrigerator 1 is provided with the fifth blowing air path 411 and the fifth return air path 412 behind the vacuum heat insulating material 500A1. The fifth blowing air path 411 and the fifth return air path 412 are formed to overlap front and back, and are insulated in vacuum The width direction of the material 500A1 is bifurcated in two.

因此，依據冰箱1，無須使風路構成複雜化，能夠實現風路構成的簡便化。 Therefore, according to the refrigerator 1, there is no need to complicate the configuration of the air duct, and the configuration of the air duct can be simplified.

在從正面觀看的狀態下，冰箱1之第4回流口331形成於在蔬菜室31的背面部50F之分岔的左側第5吹出風路411A及左側第5回流風路412A、及右側第5吹出風路411B及右側第5回流風路412B之間。 In a state viewed from the front, the fourth return opening 331 of the refrigerator 1 is formed on the left fifth blowing air path 411A, left left fifth return air path 412A, and right fifth Between the blowing air path 411B and the right fifth return air path 412B.

因此，依據冰箱1，無須使風路構成複雜化，就能夠有效運用蔬菜室31之背面部50F側的空間。 Therefore, according to the refrigerator 1, it is possible to effectively use the space on the back side 50F side of the vegetable compartment 31 without complicating the configuration of the air passage.

冰箱1，由於真空隔熱材500A1具有較冷卻器600的寬幅還要大的寬幅，所以獲致高隔熱效果。 In the refrigerator 1, the vacuum heat insulating material 500A1 has a wider width than that of the cooler 600, so a high heat insulating effect is obtained.

冰箱1配置由上方起依序為製冰室21、蔬菜室31、冷凍室41，所以能夠在維持隔熱效果的同時，提高使用者的便利性。 The refrigerator 1 is arranged from the top into the ice making compartment 21, the vegetable compartment 31, and the freezing compartment 41, so that the user's convenience can be improved while maintaining the heat insulation effect.

實施形態2. Embodiment 2.

圖8為概略顯示本發明的實施形態2之冰箱1A的一部份的剖面放大的剖面圖。基於圖8，說明本發明的實施形態2之冰箱1A。圖8係對應於實施形態1所示之圖6。圖8中，以箭頭表示空氣流。 FIG. 8 is an enlarged cross-sectional view schematically showing a part of the refrigerator 1A according to Embodiment 2 of the present invention. Based on FIG. 8, the refrigerator 1A according to Embodiment 2 of the present invention will be described. Fig. 8 corresponds to Fig. 6 shown in the first embodiment. In FIG. 8, the air flow is indicated by arrows.

另外，實施形態2中，係以與實施形態1之相異點為中心進行說明，和實施形態1相同的部分係標示以相同符號並省略其說明。 In addition, in the second embodiment, the differences from the first embodiment are mainly described, and the same parts as in the first embodiment are denoted by the same symbols and their description is omitted.

實施形態2中，第5吹出風路411的構成與實施形態1中已說明的第5吹出風路411相異。為了方便與實施形態1的第5吹出風路411有所區別，在實施形態2中以第5吹出風路411C來進行說明。實施形態2的除此之外的構成，則和實施形態1中所說明的一樣。不過，如圖8所示，冷凍室41中收納了第1冷凍室貯藏盒440A及第2冷凍室貯藏盒440B。 In the second embodiment, the configuration of the fifth blowing air path 411 is different from the fifth blowing air path 411 described in the first embodiment. In order to facilitate the difference from the fifth blowing air duct 411 of the first embodiment, the fifth blowing air duct 411C will be described in the second embodiment. The other configurations of Embodiment 2 are the same as those described in Embodiment 1. However, as shown in FIG. 8, the first freezer compartment storage box 440A and the second freezer compartment storage box 440B are stored in the freezer compartment 41.

第2冷凍室貯藏盒440B配置於第1冷凍室貯藏盒440A的上方，其容積小於第1冷凍室貯藏盒440A。第2冷凍室貯藏盒440B收納於第1冷凍室貯藏盒440A中，在門片部31A關閉的狀態下，第2冷凍室貯藏盒440B的後方的上方開放端位於較第1冷凍室貯藏盒440A的後方之上方開放端還要靠前方之處。另外，冷凍室41中收納的貯藏盒的個數並不特別限定，但至少收納第1冷凍室貯藏盒440A及第2冷凍室貯藏盒440B即可。 The second freezer compartment storage box 440B is disposed above the first freezer compartment storage box 440A, and has a smaller volume than the first freezer compartment storage box 440A. The second freezer compartment storage box 440B is housed in the first freezer compartment storage box 440A, and the upper open end of the rear of the second freezer compartment storage box 440B is located higher than the first freezer compartment storage box 440A in a state where the door section 31A is closed. The open end of the upper part of the rear should also be close to the front. In addition, the number of storage boxes stored in the freezer compartment 41 is not particularly limited, but at least the first freezer compartment storage box 440A and the second freezer compartment storage box 440B may be stored.

第5吹出風路411C和實施形態1中已說明的第5吹出風路411一樣，具有吹出到冷凍室41的冷氣流經的冷凍室吹出風路的功能。第5吹出風路411分岔為左側第5吹出風路411A和右側第5吹出風路411B。而且，冰箱1A中，左側第5吹出風路411A及右側第5吹出風路411B又再分岔。在此，係以第5吹出風路411C為左側第5吹出風路411A來進行說明。 The fifth blowing air path 411C has the function of the freezing chamber blowing air path through which the cold air blown to the freezing room 41 passes, like the fifth blowing air path 411 described in the first embodiment. The fifth blowing air path 411 branches into a left fifth blowing air path 411A and a right fifth blowing air path 411B. Furthermore, in the refrigerator 1A, the left fifth blowing air passage 411A and the right fifth blowing air passage 411B are branched again. Here, the description will be made with the fifth blowing air passage 411C as the left fifth blowing air passage 411A.

如圖8所示，第5吹出風路411C在冷凍室41中分岔。分岔出來的一方的第5吹出風路411C稱之為下段第5吹出風路411C-1，分岔出來的另一方的 第5吹出風路411C稱之為上段第5吹出風路411C-2。 As shown in FIG. 8, the fifth blowing air path 411C branches in the freezing compartment 41. The branched fifth blowing air path 411C is called the lower fifth blowing air path 411C-1, and the branched fifth blowing air path 411C is called the upper fifth blowing air path 411C-2 .

下段第5吹出風路411C-1具有吹出到冷凍室41的第1冷凍室貯藏盒440A的冷氣流經的冷凍室吹出風路的功能。在下段第5吹出風路411C-1中形成圖示省略的吹出口。流經下段第5吹出風路411C-1的冷氣，透過吹出口被導入冷凍室41的第1冷凍室貯藏盒440A。另外，從正面觀看冰箱1A的狀態下，下段第5吹出風路411C-1的吹出口可以形成於較上段第5吹出風路411C-2的吹出口靠下方的位置。下段第5吹出風路411C-1之吹出口的個數並不特別限定。 The lower fifth blowing air duct 411C-1 has a function of a freezer compartment blowing air duct through which the cold air flow blown to the first freezer compartment storage box 440A of the freezer compartment 41 passes. A blow-out port (not shown) is formed in the lower fifth blow-out air path 411C-1. The cold air flowing through the lower fifth blowing air path 411C-1 is introduced into the first freezer compartment storage box 440A of the freezer compartment 41 through the outlet.

The rear end of the vacuum heat insulating material 500A4 is located a length D2 behind the rear end of the bottom surface of the first vegetable compartment storage box 420A housed in the vegetable compartment 31. This suppresses the low temperature of the first vegetable compartment storage box 420A due to heat absorption from the freezing compartment 41.

像這樣，在冰箱1B中，於隔板53設置真空隔熱材500A2，於隔板54設置真空隔熱材500A4。藉此，抑制因為從位於蔬菜室31之上下的冷凍溫度帶的貯藏室的吸熱，使得蔬菜室31的第1蔬菜室貯藏盒420A及第2蔬菜室貯藏盒420B的內部變得低溫。 As described above, in the refrigerator 1B, the vacuum heat insulating material 500A2 is provided on the partition 53, and the vacuum heat insulating material 500A4 is provided on the partition 54. Thereby, it is suppressed that the inside of the first vegetable compartment storage box 420A and the second vegetable compartment storage box 420B of the vegetable compartment 31 becomes low in temperature due to the heat absorption from the storage compartment located above and below the vegetable compartment 31.

繼之，說明真空隔熱材500A1和空氣循環路徑80之一部分的關係。 Next, the relationship between the vacuum heat insulating material 500A1 and a part of the air circulation path 80 will be described.

真空隔熱材500A1設置在冷卻器600的前面側。另外，真空隔熱材500A1固定為下端位於箱體50的前面部50A側、上端位於箱體50的背面部50F側的傾斜的配置。而且，真空隔熱材500A1構成為具有較冷卻器600的寬幅還要大的寬幅。 The vacuum heat insulating material 500A1 is provided on the front side of the cooler 600. In addition, the vacuum heat insulating material 500A1 is fixed in an inclined arrangement where the lower end is located on the front side 50A side of the case 50 and the upper end is located on the rear side 50F side of the case 50. Moreover, the vacuum heat insulating material 500A1 is configured to have a wider width than that of the cooler 600.

而且，如圖9所示，在離開真空隔熱材500A的寬幅方向的冷卻器600的右側面形成第1回流風路141。另外，第3回流風路242及第4回流風路312形成於第1回流風路141的前方。冷卻器600的左側面構成與蔬菜室31的壁部，其一部分具有第4回流風路312的功能。 As shown in FIG. 9, the first return air path 141 is formed on the right side surface of the cooler 600 in the width direction away from the vacuum heat insulating material 500A. In addition, the third return air path 242 and the fourth return air path 312 are formed in front of the first return air path 141. The left side surface of the cooler 600 constitutes a wall portion with the vegetable compartment 31, and a part of it has the function of the fourth return air path 312.

另外，在真空隔熱材500A1的背面側且於真空隔熱材500A1的寬幅方向投影範圍內，與真空隔熱材500A1的傾斜略並行地形成第5吹出風路411。而且，在第5吹出風路411的背面側，形成第5回流風路412。第5吹出風路411及第5回流風路412構成為同樣寬幅。在從正面觀看冰箱1B的狀態下，第5吹出風路411和第5回流風路412係重疊配置。第5回流風路412路構成為與冷卻器室27接合，使得空氣流入冷卻器600的前面之下端到中段。另外，第5吹出風路411的寬幅和第5回流風路412的寬幅不必為完全相同寬幅。 In addition, the fifth blowing air path 411 is formed slightly parallel to the inclination of the vacuum heat insulating material 500A1 on the back side of the vacuum heat insulating material 500A1 and within the projection range of the vacuum heat insulating material 500A1 in the wide direction. Further, on the back side of the fifth blowing air path 411, a fifth return air path 412 is formed. The fifth blowing air path 411 and the fifth return air path 412 are configured to have the same width. In a state where the refrigerator 1B is viewed from the front, the fifth blowing air path 411 and the fifth return air path 412 are arranged to overlap. The fifth return air path 412 is configured to engage with the cooler chamber 27 so that air flows into the lower front end of the cooler 600 to the middle. In addition, the width of the fifth blowing air path 411 and the width of the fifth return air path 412 need not be the same width.

另外，在冰箱1B中，藉由將真空隔熱材500A1傾斜配置，已圖蔬菜室31之上方的空間(亦即蔬菜室31的容積)之擴大。亦即，依據冰箱1B，能夠使得蔬菜室31的上部之進深為深的構造。 In addition, in the refrigerator 1B, the space above the vegetable compartment 31 (that is, the volume of the vegetable compartment 31) is enlarged by arranging the vacuum heat insulating material 500A1 at an angle. That is, according to the refrigerator 1B, the depth of the upper part of the vegetable compartment 31 can be deepened.

將可自由移動的第2蔬菜室貯藏盒420B收納在此部分中。將真空 隔熱材500A1傾斜配置，藉此以圖蔬菜室31的上方之空間的擴大，另一方面，必須使第1蔬菜室貯藏盒420A為對應於真空隔熱材500A的傾斜配置的形狀。亦即，雖然能夠擴大第1蔬菜室貯藏盒420A的收納容積，但可能導致有損於使用者之便利性的形狀。相對於此，在冰箱1B中，使第1蔬菜室貯藏盒420A及第2蔬菜室貯藏盒420B重疊配置，藉此，能夠縮小無效收納容積，而且可提高對應於食品大小的整理性。 The freely movable second vegetable compartment storage box 420B is stored in this part. By arranging the vacuum heat insulating material 500A1 obliquely to expand the space above the vegetable compartment 31 in the figure, on the other hand, it is necessary to make the first vegetable compartment storage box 420A have a shape corresponding to the oblique arrangement of the vacuum heat insulating material 500A. That is, although the storage volume of the first vegetable compartment storage box 420A can be enlarged, it may result in a shape that impairs the user's convenience. On the other hand, in the refrigerator 1B, the first vegetable compartment storage box 420A and the second vegetable compartment storage box 420B are arranged in an overlapping manner, whereby the ineffective storage volume can be reduced, and the tidyness corresponding to the size of the food can be improved.

另外，藉由將真空隔熱材500A1傾斜配置，以圖箱體50的蔬菜室31之背面部50F側的空間之擴大。因此，能夠使得位於蔬菜室31的背面部50F側的第5吹出風路411及第5回流風路412為直線構成。因此，能夠減少朝向最必須要有冷卻能力的冷凍室41的第5吹出風路411及第5回流風路412的彎曲及風路面積的變化，以圖降低壓力損失。而且，第5回流風路412可以形成為使空氣流入冷卻器600的前面之下端到中段，使空氣流入冷卻器600的前面前緣，可以提高冷卻器600的熱交換效率。 In addition, by arranging the vacuum heat insulating material 500A1 at an angle, the space on the back side 50F side of the vegetable compartment 31 of the cabinet 50 is enlarged. Therefore, the fifth blowing air path 411 and the fifth return air path 412 on the side of the rear surface portion 50F of the vegetable compartment 31 can be linearly configured. Therefore, it is possible to reduce the curvature of the fifth blowing air path 411 and the fifth return air path 412 toward the freezer compartment 41 where cooling capacity is most necessary, and the change in the air path area, in order to reduce the pressure loss. Furthermore, the fifth return air path 412 may be formed so that air flows into the lower front end of the cooler 600 to the middle section, and air flows into the front front edge of the cooler 600, thereby improving the heat exchange efficiency of the cooler 600.

<冰箱1B發揮的效果> <Effect of Refrigerator 1B>

如上述，冰箱1B之真空隔熱材500A1係傾斜配置，使其下端位於前面部50A側、其上端位於背面部50F側，以圖蔬菜室31的容積之擴大。 As described above, the vacuum heat insulating material 500A1 of the refrigerator 1B is inclinedly arranged such that its lower end is located on the front side 50A side and its upper end is located on the rear side 50F side, as shown in FIG.

冰箱1B中，真空隔熱材500A4的後方端，位於較第1蔬菜室貯藏盒420A的底面的後方端更靠背面側，真空隔熱材500A2的後方端位於較第2蔬菜室貯藏盒420B的上方的後方端更靠背面側。 In the refrigerator 1B, the rear end of the vacuum insulation material 500A4 is located on the back side of the rear end of the bottom surface of the first vegetable compartment storage box 420A, and the rear end of the vacuum insulation material 500A2 is located on the back side of the second vegetable compartment storage box 420B The upper rear end is closer to the back side.

因此，依據冰箱1B，抑制因為製冰室21、溫度切換室22、及冷凍室41的吸熱，使得第1蔬菜室貯藏盒420A及第2蔬菜室貯藏盒420B變得低溫。 Therefore, according to the refrigerator 1B, it is suppressed that the first vegetable compartment storage box 420A and the second vegetable compartment storage box 420B become low in temperature due to the heat absorption of the ice making compartment 21, the temperature switching compartment 22, and the freezing compartment 41.

冰箱1B構成為，第5吹出風路411及第5回流風路412形成為前後重疊，第5回流風路412使空氣回到冷卻器600的前面之下端到中段。 The refrigerator 1B is configured such that the fifth outlet air path 411 and the fifth return air path 412 are formed to overlap front and back, and the fifth return air path 412 returns air to the lower front end of the cooler 600 to the middle.

因此，依據冰箱1B，可以提高冷卻器600的熱交換效率。 Therefore, according to the refrigerator 1B, the heat exchange efficiency of the cooler 600 can be improved.

冰箱1B，設置了蓋構造體430，其形成附加部430A，並覆蓋第2蔬菜室貯藏盒420B的上方開放面。 The refrigerator 1B is provided with a lid structure 430 which forms an additional portion 430A and covers the upper open surface of the second vegetable compartment storage box 420B.

因此，依據冰箱1B，不僅是將水分鎖在蔬菜室31中，還能夠將第1蔬菜室貯藏盒420A及第2蔬菜室貯藏盒420B的內部維持在高濕度。 Therefore, according to the refrigerator 1B, not only the moisture is locked in the vegetable compartment 31, but also the inside of the first vegetable compartment storage box 420A and the second vegetable compartment storage box 420B can be maintained at high humidity.

冰箱1B配置由上方起依序為製冰室21、蔬菜室31、冷凍室41，所以能夠在維持隔熱效果的同時，提高使用者的便利性。 The refrigerator 1B is arranged from the top into the ice making compartment 21, the vegetable compartment 31, and the freezing compartment 41 in sequence, so that the user's convenience can be improved while maintaining the heat insulation effect.
