Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator having a storage compartment divided into left and right.

In a refrigerator having a freezer compartment for freezing and storing a stored object, a front surface thereof is opened and closed by an insulated door, and a heat insulating wall is disposed between other storage rooms such as a refrigerating chamber for storing and storing the stored product. Since the room temperature of the freezer is lower than the room temperature of the room where the refrigerator is installed and the room temperature of the refrigerating chamber, condensation is prevented by the heat insulation door and the heat insulation wall.

In the case where the temperature of the freezing chamber is uneven, it is necessary to form the heat insulation door and the heat insulation wall thickly in consideration of being lower than the set temperature, resulting in a problem of low volumetric efficiency. For this reason, the refrigerator which partitions a freezer compartment with the vertical partition plate installed in the center of a freezer compartment, narrows the volume of the 1st, 2nd storage compartment divided left and right, and is known is uniform.

The cold air circulation structure of the refrigerator is disclosed in Patent Document 1. Fig. 5 is a side sectional view showing a freezer compartment of this refrigerator. The refrigerator 1 is provided with the main-body part 2 which has the heat insulation box 2a which opens a front surface. The refrigerating chamber 3 is arrange | positioned at the upper part of the main-body part 2, and the freezing chamber 4 is arrange | positioned below through the heat insulation wall 10. As shown in FIG. The front surfaces of the refrigerating chamber 3 and the freezing chamber 4 are opened and closed by the insulating doors 3a and 4a, respectively. In the freezer compartment 4, a plurality of storage cases 12 for storing a storage object are provided.

At the rear of the freezing chamber 4, a rear duct 6 covered with the rear plate 5 is formed. The inside of the back duct 6 is divided back and forth by the partition plate 6a, and the cooler 7 is arrange | positioned at the back side, and the blower 8 is arrange | positioned above the cooler 7. A part of the back duct 6 is provided with a return passage 6b for inducing cold air to the cooler 7. The cooler 7 is connected to the compressor 9 arranged under the main body 2. The refrigerant is circulated by the drive of the compressor 9 so that the refrigeration cycle is driven, and the cooler 7 is at the low temperature side of the refrigeration cycle.

The cool air generated by heat exchange in the cooler 7 is led to the front side of the rear duct 6 by the driving of the blower 8. The cold air is dispersed up and down from the plurality of rear discharge ports 13 provided in the rear plate 5 and discharged into the freezing chamber 4. The cold air discharged to the freezing chamber 4 is led forward and flows around the storage case 12, flows into the return passage 6b through the cold air return opening 14, and returns to the cooler 7. As a result, the inside of the freezing chamber 4 is cooled. Moreover, the damper 15 provided in the heat insulation wall 10 is opened, and cold air is sent to the refrigerating chamber 3.

However, according to the conventional refrigerator 1, the rear discharge port 13 and the cold air return port 14 are disposed to approach. For this reason, a short circuit in which a part of the cold air discharged from the rear discharge port 13 flows into the cold air return port 14 without circulating inside the freezing chamber 4 occurs. Thereby, while cooling efficiency fell, the front part of the freezer compartment 4 lacked cooling, and there existed a problem that room temperature cannot be fully uniformed.

It is possible to reduce the short circuit by arranging the return passage 6b from the rear surface of the freezing chamber 4 to the bottom surface and arranging the cold air return port 14 in front. However, since the return passage 6b is disposed along the lower portion of the heat insulating housing 2a protruding forward by the compressor 9, the depth of the storage case 12 cannot be secured widely and the storage of the freezing compartment 4 is accommodated. The problem is that the volume decreases.
