One compressor and one cooler are mounted, and the cooler is placed in a cooling chamber above the main body, sends cold air from the cooling chamber to the lower freezing chamber, circulates the freezing chamber, and forms a circulating cold air returning to cooling. Cooling the refrigerating compartment installed through the partition plate at the bottom of the freezing compartment, and is installed separately inside the freezing compartment, and is connected to the freezing compartment and the refrigerating compartment by the cooling discharge tube and the refrigerating suction tube. The refrigerator introduced and performed can be seen conventionally, as shown to Unexamined-Japanese-Patent No. 60-9663.

However, in the conventional refrigerator presented in the above publication, the effective content of the freezer compartment is inevitably reduced in volume due to the refrigeration discharge and the presence of the suction pipe.

In addition, the complicated task of assembling two tubes was forced, and assembly was very difficult.

In addition, the net shelf installed in the freezer compartment and the net shelf installed in the refrigerating compartment is different in size and each must be prepared separately, each has a defect that leads to an increase in the number of parts.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a refrigerator which is further improved in securing a wide effective contents in the freezer compartment, facilitating a pipe attachment process, and in terms of manufacturing, structural and usability such as common use of parts. It aims to provide.

The space formed as the heat insulation plate 10 which electrically connected with this cooler cover 17 as the cooler cover which is attached and fixed by it becomes the cooling chamber 7 mentioned above.

The cooler cover 17 described above has a bottom inclined to one side, and the bottom face is formed with a round hole directed to the freezer compartment cold air blower 9 described above, and becomes the inlet 19 of the freezer compartment cold air. The rear end of the portion is cut off and serves as the discharge port 20 of the freezer compartment cold air.

Therefore, the cooling chamber 7 described above and the freezing chamber 4 described above communicate with each other by the suction port 19 and the discharge port 20.

In addition, a drainage plate 21 is disposed on the inner surface side of the cooler cover 17, and the water drain 22a and the drain hose 22b are received by receiving the water at the time of defrosting of the cooler 8, which has been removed. It is drained out of the main body by way of gas.

However, when the cooling operation is performed and the freezer compartment cold air circulation blower 9 described above is driven, in the freezer compartment 4 described above, the air inlet of the freezer compartment 4, which is delivered from the freezer compartment 4, which is aired by the freezer compartment 4, 19, which is sucked through the cooler 8 described above, becomes cold, and the freezer compartment circulated through the intake port 19, which is circulated in the freezer compartment 4, which has been delivered from the discharge port 20, which is electrical electricity. The circulation flow shown by the arrow A of FIG. 3 returning to the cooling chamber 7 mentioned above from (4) is formed, and the inside of the freezer compartment 4 mentioned above is cooled.

25 is a refrigeration discharge tube for guiding a part of the cold air near the inlet port 19 described above to the freezer compartment 5 which has been delivered by a freezer compartment cold air circulation blower (to be described later).

The refrigeration chamber 25 described above and the refrigeration suction tube 26 described above are embedded in the left and right heat insulating side walls 2A and 2B, so that the tube is not present in the freezer compartment 4, and thus the freezer compartment ( 4) Since all of them can be used as a storage unit, unlike in the prior art, a lot of effective contents are secured.

Then, both the refrigeration discharge tube 25 and the refrigeration suction tube 26 described above have bent portions 25a and 26a which are bent at right angles to the cooling chamber 7 described above and extended horizontally. The refrigerating chamber 5 in which the hole at the end of the bent portion 25a becomes the cold air inlet 27 into the refrigerating chamber 5 which has been posted, and the hole at the end of one bent portion 26a is joined to the cold of the freezer compartment. The cold air discharge port 28 which discharges the cold air from the inside into the cooling chamber 7 which was electric was used.

Naturally, the opening at the lower end of the refrigerating discharge tube 25 is the discharge port 29 of the introduced cold air, and the opening at the lower end of the refrigerating suction tube 26 is the refrigerating chamber cold air. It becomes a suction port 30 for returning to the cooling chamber 7 which was transmitted through the above-mentioned refrigeration suction pipe 26.
