Description of the Related Art Conventionally, this type of refrigerator is composed of an insulating box body in which an insulating material such as foamed polyurethane is filled by an in-situ foaming method between an outer box made of steel plate and an inner box made of hard resin. By partitioning the inside of the heat-insulating box (inside the warehouse),
A freezer that is cooled to a freezing temperature such as -20 ° C or + 5 ° C
It defines a refrigerating room that is maintained at a refrigerating temperature such as, and a vegetable room for storing foods such as vegetables that do not want to be dried.

空断熱材が用いられるようになって来た。Further, in recent years, it is necessary to reduce the wall thickness of the heat insulating box in order to expand the effective volume in the refrigerator while reducing the installation space of the refrigerator or preventing its expansion. For example, Japanese Patent Publication No. 61-17263 (B32B5 / 18), Japanese Patent Publication No. 63-35911 (F25D23 / 06), or Japanese Patent Publication No. 2-544.
Vacuum heat insulating materials as disclosed in Japanese Patent Publication No. 79 (F16L59 / 06) have come to be used.

したものである。This vacuum heat insulating material is a bag formed by fusing the periphery of a film (gas barrier film) having a multilayer laminate structure that blocks the permeation of gas (air etc.), fine powder such as silica and pearlite, and glass. After inserting a heat insulating material made of fiber or open-cell polyurethane foam, the gas in the bag is evacuated and sealed in a vacuum state.

Since a thermal conductivity of 0.010 Kcal / mh ° C is achieved, it can be installed from the outside of the outer box even if the wall thickness of the heat-insulating box is reduced by placing it on the inner surface of the outer box around the freezing room where particularly low temperature is required. It can be expected that the heat entering the freezer can be effectively reduced.

低温となる冷凍室からの温度影響を受けて野菜室の温度
低下が著しくなる。By the way, the heat insulating partition wall for partitioning each chamber has conventionally been formed of a molded heat insulating material such as styrofoam. Therefore, particularly in the case where the freezing compartment and the vegetable compartment are adjacent to each other as described above, the temperature of the vegetable compartment is significantly lowered due to the influence of the temperature from the lowest freezing compartment.

Since the second storage chamber is also partitioned, the temperature effect from the cooling chamber when the cooling chamber where the temperature is to be lowered most is formed behind the second storage chamber. It is possible to effectively prevent or suppress the temperature decrease of the second storage chamber due to the above. Particularly, since the three chambers are divided by the same heat insulating partition wall, the number of parts can be further reduced.
