Description

[Detailed Description of the Invention] The present invention relates to a two-temperature type refrigerator, and its purpose is to easily form both freezing and refrigerating compartments and to improve the temperature distribution between the left and right sides of the refrigerating compartment.

The following is an explanation of the embodiment of the present invention with reference to the drawings: 1
1 is a refrigerator whose main body is composed of a heat insulating wall 2 with an opening at the front, and an L-shaped heat insulating plate 3 is installed at the lower left side of the interior defined by the heat insulating wall, and 1/2 of the inside of the refrigerator is 4 is a freezer compartment 4, and 3/4 is a refrigerator compartment 5. In the refrigerator compartment 4, a partition plate 8 having an air outlet 6 in two parts and an air inlet 7 in the lower part is arranged at a distance from the back wall. to form a cold air passage 11 in which a cooler 9 and a blower 10 are installed,
Further, a duct plate 12 is disposed at a distance from the side wall 3b of the heat insulating plate 3 to form a side passage 13. Inside the side wall 3b of the heat insulating board, there is a supply passage 14 which opens one end to the side passage 13 and the other end to a communication passage to be described later, and a supply passage 14 which opens one end to the side passage 13 and the other end to the lower part of the refrigerator compartment 5. A return path 15 is formed. Reference numeral 16 denotes a communication path extending upward from the upper wall 3a of the heat insulating plate through approximately the center of the refrigerator compartment 5, the upper end of which has an air outlet 17 on the front and suction holes 1 for short cycles on both sides.
It is connected to a blow-off duct 20 formed with 8A and 18B and housing a blower 19 therein, and also connected to a supply path 14 having an open bottom end. The opening area of the suction holes 18A and 18B of the blowout duct is the same as that of the large room 5 of the refrigerator compartment 5.
Since the volumes of A and small chamber 5B are different, the large chamber 5A side is made larger.

Next, to explain the cold air circulation in the freezer compartment 4 and the refrigerator compartment 5, the cold air that has been heat exchanged with the cooler 9 is blown out from the air outlet 6 by the blower 10, most of it is in the freezer compartment 4, and part of it is in the side passage. 13 and return to the suction port 7 as shown by the arrow. A part of the cold air passing through the side passage 13 is diverted from the supply passage 14 and passes through the communication passage 16 as shown by the chain arrow to reach the blow-off duct 20, and this duct short-cycles the refrigerator compartment 5 through the suction hole 1.
It joins with the cold air (indicated by a dashed line) from 8A and 18B and is blown out from the air outlet 17 into the refrigerator compartment 5.
The cold air that has passed through the refrigerator compartment 5 passes through the return path 15 and then enters the side path 1.
The cold air passing through 3 is joined together and reaches the suction port 7.

According to such a configuration, the cold air supply path 1 to the refrigerator compartment 5
Since the L-shaped heat insulating board 3 with the cold air return path 15 from the refrigerator compartment 4 and the refrigerator compartment 5 formed in advance on the side wall 3b is disposed inside the refrigerator, the formation of the freezer compartment 4 and the refrigerator compartment 5 can be easily performed. At the same time, the upper wall 3 of the insulation board 3
a serves as a product placement part, which makes it easy to store and take out products in the small compartment 5B of the refrigerator compartment 5, and the air outlet duct 20
By making the opening areas of the suction holes 18A and 18B asymmetric, it is possible to maintain a substantially uniform temperature distribution on the left and right sides of the refrigerator compartment 5.

In addition, as a means to maintain a substantially uniform temperature distribution on the left and right sides of the refrigerator compartment 5 without making the opening areas of the suction holes 18A and 18B asymmetric, as shown in FIG. It is sufficient to set it in

As described above, in this case, an L-shaped heat insulating board consisting of an upper wall and a side wall forming a cold air supply path to the refrigerator compartment and a cold air return path from the refrigerator compartment is placed below either the left or right side of the refrigerator. The refrigerator compartment is made up of a freezer compartment and a large compartment and a small compartment.The connecting passage is connected to the cold air supply passage and extends upward from the center of the refrigerator compartment.The upper end of the communication passage is connected to the cold air supply passage and is arranged to extend upward from the center of the refrigerator compartment. Since it is characterized by having an air outlet duct with a suction hole for the shot cycle having an asymmetrical opening area on its surface, it is not only possible to easily form both freezing and refrigerating chambers using the heat insulating board. The top wall of the insulation board can be used as a product placement area in the small compartment of the refrigerator, and the side wall can be used as part of the circulation path, and the asymmetrical suction holes can adjust the amount of cold air blown out to the large and small compartments. It is possible to maintain a uniform temperature distribution in the refrigerator compartment by setting an appropriate air volume.
