[Action]
Conventionally, various methods have been used in order to prevent the cold air in the refrigerator compartment from flowing out to the outside when the refrigerator compartment door is opened.
For example, by installing a vinyl curtain in the opening of the refrigerator compartment, there is one that suppresses the cold air in the refrigerator compartment from flowing out. In this case, the vinyl curtain must be opened after the refrigerator compartment door is opened in order to search for food in the refrigerator compartment. Therefore, the opening time of the refrigerator compartment door becomes long, and it is sufficient that the cold air in the refrigerator compartment flows out to the outside. It was not something that could be suppressed. In addition, since the vinyl curtain blocks the refrigerator compartment door and the refrigerator compartment door, the cool air is not sufficiently sent to the storage case provided on the refrigerator compartment door side, and the temperature of food stored in the storage case is sufficiently lowered. There were times when I couldn't let you.

  In another example, a small door that closes the opening formed in the refrigerator compartment door is provided, and food stored in the storage case of the refrigerator compartment door is taken out from the small door without opening the refrigerator compartment door. In some cases, the cold air in the refrigerator compartment is prevented from flowing out. In this case, a favorite food drink or the like is not necessarily stored in the position corresponding to the small door, and in fact, it is often taken after seeing the food drink or the like actually stored in the refrigerator. Therefore, the refrigerator compartment door is eventually opened, and the outflow of cold air in the refrigerator compartment cannot be sufficiently suppressed.

  In the first embodiment, the inner door 8 is provided with a shielding plate 80 that separates the opening 2a of the refrigerating chamber 2 and the refrigerating chamber door 7, and a plurality of communication holes 81 are provided in the shielding plate 80. Even when the refrigerator compartment door 7 is opened, the shielding plate 80 can prevent cold air from flowing out from the opening 2a of the refrigerator compartment 2 to the outside. Furthermore, cold air can be sent from the refrigerator compartment 2 to the refrigerator compartment door 7 side through the communication hole 81.

  Further, in Example 1, the heat conductivity of the shielding plate 80 was made higher than the heat conductivity of air. Therefore, the air on the refrigerator compartment door 7 side can be cooled.

  Furthermore, in Example 1, the storage case 82 that can store foods and the like was formed on the side of the refrigerator compartment door 7 of the shielding plate 80. When the refrigerator compartment door 7 is opened, an accommodation space for food or the like is secured by the accommodation case 70 accommodated in the refrigerator compartment door 7 and the accommodation case 82 formed on the heat shield plate 80. Therefore, the number of times of opening the inner door 8 can be reduced by storing the beverages and the like that are frequently taken in and out in the storage cases 70 and 82.
