であつた。 In the refrigerator configured in this way, the cold air cooled by the cooler 5 is circulated and cooled in the freezer compartment 1 by the fan 6, and the cold air introduced from the rear duct 8 is used to cool the refrigerator compartment 2 and the ice temperature case. 4. Furthermore, circulate cold air in the vegetable compartment 3. Since the temperature control device 7 that controls the temperature of the refrigerator compartment 2 cools the ice-temperature case 4 and the vegetable compartment 3 with controlled cold air, it depends on the temperature of the refrigerator compartment 2, especially the ice-temperature case 4. This was less than the ideal condition of keeping the food at a temperature just above the freezing temperature. In addition, in the vegetable compartment 3, a part of the cold air that cools the refrigerator compartment 2, which enters from the cold air inlet 17 on the back side of the refrigerator compartment partition plate 16, circulates through the vegetable compartment 3 and circulates through the vegetable compartment partition plate 16. Cooling was performed by returning to the refrigerator compartment 2 from the front return hole 29, and the temperature was also slightly high.

の前面戻り孔２９から冷蔵室２へと戻る。 In the refrigerator configured as above, cooling is performed as follows. That is, the cold air cooled by the cooler 5 is blown out from the freezer compartment outlet 9 by the fan 6 to cool the inside of the freezer compartment 1 to -18°C. On the other hand, a part of the cold air passes through the freezer compartment rear duct 8, is branched in the middle, and one side is blown out from the refrigerator compartment blow-off duct 11, and is heated by the temperature sensor 7a of the refrigerator compartment temperature control device 7. It opens and closes to control the temperature inside the refrigerator compartment 2 at around 3°C. In addition, the other branched cold air is sent to the ice chamber temperature control device 13 by a full 13b.
By opening and closing, the water flows into the back duct 15 of the ice room and is guided to the ice room 12, where the temperature of the ice room 12 reaches 0°C, which is on the verge of freezing.
The temperature is precisely controlled to a certain degree. The cold air led to the ice room 12 flows into the ice temperature case 23, while the remaining cold air is heated to the ice temperature, the vegetable compartment partition plate 19,
It flows into the vegetable compartment 3 from the back cold air inlet 20, flows into the vegetable compartment 3, and cools the vegetable compartment 3. In addition, the cold air that has been cooled by circulating through the vegetable compartment 3 passes through the front return hole 21 of the vegetable compartment partition plate 19, and is further formed between the front wall 25 of the freezing case 23 and the inner plate 24 of the freezing greenhouse door. The refrigerator/ice chamber partition plate 28 passes through a ventilation passage 26 having a cross-sectional area equal to or larger than that of the front return hole 21
It returns to the refrigerator compartment 2 through the front return hole 29.

そして上記戻り冷気は冷蔵室を循環した冷気と
ともに公知の冷蔵庫と同様に冷凍、冷蔵室仕切壁

戻るように構成している。 The returned cold air is configured to return to the cooler room along with the cold air that circulated through the refrigerator compartment through a suction port opened on the front lower surface of the freezer/refrigeration compartment partition wall, similar to known refrigerators.

効果が得られる。 As mentioned above, this idea eliminates the high temperature caused by conventionally cooling the vegetable compartment by letting cold air from the refrigerator flow in, and eliminates the cold air from the ice room that is precisely controlled to about 0°C. By introducing this, the temperature can be lowered than before, and the shelf life can be further improved. In addition, the cold air return structure of the vegetable room can be easily and inexpensively created by forming an air path between the front wall of the freezing case of the icehouse and the inner plate of the icehouse door. Effects can be obtained.

多大の実用的効果を有するものである。 Furthermore, in order to prevent the cold return air from the ice room from mixing with the cold return air from the vegetable compartment, and to prevent the heat effect from the cold return air from the vegetable compartment from affecting the ice room, the refrigerator is placed in contact with the front edge of the ice room. , a packing box hangs down from the partition board of the ice room, and cold air return holes are provided at the front and rear of the packing box.The temperature control of the vegetable room can be controlled by increasing the number of air passage holes in the cold air return hole, or conversely decreasing the temperature. Either a shutter should be installed in the cold air return hole of the refrigerator/ice room partition plate so as to weakly cool the food by letting the food cool.
Alternatively, since both of these shutters are provided and can be adjusted, the temperature in the vegetable compartment can be controlled at an appropriate temperature, and storage stability can be improved, which has many practical effects.
