The refrigerator disclosed in Japanese Patent Application Laid-Open No. Hei 9-113108 has a refrigerator room and a low-temperature room in the upper part of the refrigerator body, a freezing room in the lower part, and a vegetable room in the middle. . A cooler and an electric fan provided at the rear of the freezing room, and one compressor are provided, and cool air is sent to each room by an electric fan through a provided cool air passage, and cooled to a set temperature. I have.

[0005]

In the two prior arts described above, since the cool air exchanged by the cooler is sent to all the chambers by the electric fan and cooled, all the chambers of one compressor are normally used. Load and the amount of power generated by operation is large. In addition, when a large amount of food is replenished suddenly or under a high load such as a high outside air temperature, a load is applied to one compressor and the life is affected. It takes a long time for the compressor, which is not preferable. Furthermore, the operation of the compressor requires a large amount of electric power, which is not preferable in terms of power saving and environment.

[0006] Further, in the above two prior arts, it is necessary to provide a cool air passage for guiding cool air to each room in a limited space of the refrigerator main body, so that the storage capacity of the whole refrigerator is adversely affected, and This is not preferable because it complicates the structure of the cool air passage and causes a cool air leak.

Further, in the above two conventional techniques, the low-temperature room is inside the refrigerator compartment and the ice storage room is inside the freezer room, so that it has no independent doors and cannot have a large storage volume, so that it is inconvenient to use.

Further, in the former of the prior art, the vegetable compartment is located at the lower part of the refrigerator body, so that the user has to bend down to put in and out heavy vegetables, which is inconvenient.

The present invention solves the above-mentioned problems, and
By cooling the room with the highest temperature with conduction and radiant heat from the surroundings, the structure of the cold air passage was simplified, thereby increasing the storage capacity of the entire refrigerator, and saving power and improving the usability of each room. Provide refrigerator.

In addition, food can enter and exit from the cold room 6 and the vegetable room 9 in an easy posture.

Further, since the low-temperature chamber 6 is controlled by the temperature control means 30 such as a single damper, fine cooling control with less load fluctuation can be performed, and the cool air passage to the low-temperature chamber 6 can be shortened. In such a low-temperature room 6, cold air is radiated from the front side of the low-temperature room 6 through a low-temperature room passage 4a in the heat insulating partition wall 4,
It is like falling from the ceiling.

Remains in the freezer compartment 12 and the heat insulating partition wall 10 is located at the top. The upper case 23 can be pulled out and carried independently through the drawer means 36 as needed. Further, the cool air is discharged from the independent cool air passages 23a and 24a to the upper case 23 and the lower case 24, respectively, so that the cool air uniformly flows in each case.

Further, since the freezer passage 21 for guiding the cold air to the freezer 12 is gradually inclined toward the freezer compartment toward the freezer compartment, the cooling fan naturally descends smoothly even with its own weight, and the electric fan is cooled. In addition, the discharge force by the nozzle 19 can be reduced, the load can be reduced, and cool air can be efficiently guided.

Further, a freezer compartment return passage 31 for the cool air exchanged in the freezer compartment 12 is provided behind the freezer compartment passage 21, and a part of the inner box 14 is used in particular. Therefore,
The whole of the two cool air passages can be made compact, and the storage case can be made large.

Further, even though the freezer compartment passage 21 and the freezer compartment return passage 31 are designed to be compact, the partitioning section 35 separates them, so that the cold air does not short-circuit and is drawn out. When the door 11 is closed as usual, the lower case 24 hits the partition portion 35 to partition, so that the partition can be easily confirmed.
