Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a 5-temperature refrigerator.

(Prior Art) Fig. 9 shows a conventional example of a 5-temperature refrigerator shown in, for example, Japanese Utility Model Application Publication No. 55-54874. Cooling room 52, refrigerator room 5
3 and a vegetable compartment 54 are formed, and doors 51d, 53d, and 54d are attached to the openings of each compartment other than the cooling compartment 52.

55 is an ice maker installed in the freezer compartment 51, and 56 is a cooling compartment 52.
57 is a cold room placed on one side of the cooling room 53J, 58 is a fan placed on the top of the cooling room 52 for forced circulation of cold air, and 59 is an air blower installed at the back of the cooling room 52. A duct 60 is a communication duct provided on the back side of the refrigerator compartment 53 in communication with the blower duct 60, and guides cold air to the vegetable compartment 54. Reference numeral 61 denotes a damper, which is disposed in the communication duct 60 and whose opening and closing are controlled according to the temperature of the refrigerator compartment 53. 62 is a partition wall that separates the freezer compartment 51 and the refrigerator compartment 53, and a cold air passage 82t is provided inside the partition wall.

A suction port Ej2k is formed at the rear.

Since the conventional 5-temperature refrigerator is configured as described above,
The cold air cooled by the cooler 52 is blown out to the freezer compartment 51 by the fan 58, and after cooling the freezer compartment 51,
The air is circulated back to the cooling room 52 through the suction port 62k, and a part of the cold air cooled by the cooler 52 is divided into the communication duct 60, the low temperature room 57, and the refrigerator room 53 through the ventilation duct 59, and the cold air is cooled at a low temperature. The cold air flowing into the chamber 57 cools the cold room 57 and then circulates back to the cooling chamber 52 via the cold air passage 62t of the partition wall 62, and the cold air flowing into the refrigerator compartment 53 cools the refrigerator compartment 53. After that, the cold air passage 62t
The cold air that has flowed into the communication duct 60 is guided to the vegetable compartment 54 and cools the vegetable compartment 54.

[Problem that the invention seeks to solve]

In the conventional refrigerator, the damper 61 disposed at the entrance of the communication duct 60 is controlled to open and close depending on the temperature of the refrigerator compartment 53. Cold room 57. The temperature of the vegetable compartment 54 and the vegetable compartment 54 cannot be controlled independently.
If the refrigerator compartment 53 is strongly cooled, the temperature will drop below the optimum temperature, and conversely, if the refrigerator compartment 53 is cooled weakly, the temperature will exceed the optimum temperature, making precise temperature control difficult. Furthermore, since the freezer compartment 51 is configured to have an ice maker 55 disposed at the top and a large amount of cold air is applied to the ice maker 55, if the freezer compartment door 51d is opened and closed frequently to take out water, the freezing There was a problem in that temperature control of the chamber 51 became difficult.

[Means for solving problems]

The purpose of this invention is to control the temperature of each chamber in the refrigerator to an appropriate temperature, and the interior of the refrigerator is divided into a first freezer compartment, a second freezer compartment, a refrigerator compartment, and a vegetable compartment from above using partition walls. In the refrigerator, the refrigerator is provided with a cooling chamber at the back of the first freezer compartment and the second freezer compartment, and has an air passage in which the cooling compartment circulates cold air in a divided manner to each of the compartments, wherein the second freezer compartment is partitioned into left and right sides. It can be used as both an ice making room and a cold room.
