う問題点もあった。However, in the above-mentioned conventional construction, since one chamber is cooled by one evaporator 8 and one blower 9, the cooling air flowing through the cooling chamber 2 and the cooling chamber 7 having a particularly large cooling load is cooled. Discharge air path 15 and cool air suction air path 19
However, there has been a problem that the cooling efficiency is reduced due to an increase in wind path resistance and heat loss. Furthermore, the cold air discharge air passage 15 has a large temperature difference from the inside of the refrigerator compartment 2 and requires a considerable heat insulating structure. There was also a problem of becoming smaller.
【0017】また、一つの蒸発器8で冷却能力を確保す

あり、その結果冷蔵室2と冷凍室3間の断熱区画壁6の
位置が高くなって冷蔵室2内の使いやすい高さの収納範
囲(中央部及び下部)が圧縮され、使い勝手が悪くなる
という問題点があった。Further, it is necessary to increase the dimension of the evaporator 8 in the height direction in order to secure the cooling capacity with one evaporator 8, and as a result, the heat insulating partition wall 6 between the refrigerator compartment 2 and the freezer compartment 3 is required. There is a problem that the storage position (the central portion and the lower portion) of the refrigerator compartment 2 having a height that is easy to use is compressed and the usability is deteriorated.
【0018】また、一つの蒸発器8で貯蔵温度の異なる
複数の室を冷却するため蒸発器8の蒸発温度の設計を最

った。Further, in order to cool a plurality of chambers having different storage temperatures with one evaporator 8, it is necessary to lower the temperature of the evaporator 8 by adjusting the design of the evaporating temperature to the freezing room 3 having the lowest temperature (for example, -30). ° C), refrigeration cycle efficiency (refrigeration capacity /
Input) and power consumption increases.

という問題点があった。In addition, the refrigerator compartment 2, the vegetable compartment 10, and the low-temperature compartment 11, which have higher storage temperatures than the freezer compartment 3, are supplied with cold air at an unnecessarily low temperature, thereby promoting the drying of the stored food. Also, there is a problem that the storage quality of the stored food is deteriorated by causing partial supercooling near the cool air discharge ports 16 and 18.

た。The front part of the refrigeration compartment 2 is opened and closed by the door 4 and the door 4
Although the storage temperature tends to be high due to heat absorption due to heat absorption around the outside, the cold air discharged from the cold air discharge port 16 does not easily reach the front because the cold air discharge passage 15 is provided at the rear of the refrigerator compartment 2. The temperature unevenness in the refrigerator compartment 2 is further expanded, and the temperature in the front portion of the room is high and the temperature in the rear portion of the compartment is low,
There was also a problem that the storage quality of the stored food was not stabilized.

都合もあった。Further, since the lighting device 27 is provided on the rear surface in the refrigerator compartment 2, uneven illumination is caused only by lighting from the rear of the room, and the front portion is blocked especially when a large amount of food is stored. There was also an inconvenience that the lighting sometimes did not reach the room.

び冷凍室38内の冷却が行われる。If the temperature detector 64 in the freezer compartment 38 is higher than the set value, the compressor 66 is operated, and the refrigerant compressed to a high pressure by the compressor 66 is radiated by the condenser 67 to become a liquid refrigerant, and becomes the first refrigerant. The pressure is reduced while passing through the pressure reducer 68 and reaches the switching valve 69. At this time, first, if the temperature detector 63 in the refrigerator compartment 37 detects a temperature higher than the set value, the switching valve 69 is switched to the first refrigerant circuit 71 side, and the refrigerant flows into the compressor 66 and the condenser 67. Circulates through the first decompressor 68, the switching valve 69, the first evaporator 45, and the second evaporator 61, and absorbs heat in the first cooling chamber 44 by the first evaporator 45. The portion expands and vaporizes, and then the second evaporator absorbs heat in the second cooling chamber and expands and vaporizes. The vaporized refrigerant returns to the compressor 66, and this operation is repeated to cool the refrigerator compartment 37 and the freezer compartment 38.

戻される。That is, the cool air generated by cooling the surrounding air by the heat absorbing action of the first evaporator 45 is supplied to the first blower 4.
Due to the forced ventilation action of 6, the air passes through the cool air discharge air passage 49 in the first cooling chamber 44 and is discharged from the cool air discharge port 48 on the front to the upper front of the refrigerator compartment 37. The discharged cool air is stored in each storage section 56 of the main body side storage section 40, the vegetable room 57, and the storage room 59.
After cooling the door storage section 41, the cooling air is returned into the first cooling chamber 44 through a cold air suction port 47 provided at the lower end of the first cooling chamber 44.

And a substantially L-shaped first cooling chamber 4 provided in the top portion
Since the exclusive first evaporator 45 and the cool air discharge air passage 49 are incorporated into the inside 4 for cooling, the air passage is simplified and the effective internal volume is expanded. Further, since the first cooling chamber 44 is provided at the upper rear portion and the top portion of the refrigerator compartment, which has been conventionally inconvenient, the influence on the actual internal volume is further reduced, and the frequently used storage area which is easily reachable by the user. The usability is improved.

By providing the pressure reducing device 5, the evaporation temperature can be increased in accordance with the room temperature by appropriately setting the pressure reduction amount of the first pressure reducing device 68, and the vapor pressure difference between the room and the first evaporator 45 is reduced. Therefore, drying of the stored food is suppressed and storage quality is improved.

が高まる。Further, since the cool air having a temperature closer to the room temperature is discharged from the cool air discharge port 48 provided in the upper front surface of the refrigerator compartment 37, the temperature rise in the front of the room and the excessive cooling in the rear of the room are suppressed. Conventionally, the temperature unevenness in the room where the front part is high and the rear part is low is reduced, and the storage quality is stabilized. Further, since the cooling is performed independently of the freezing compartment 38, the storage quality is improved without being affected by the temperature rise due to the defrosting of the second evaporator 61.

便利である。Further, since the drying in the refrigerator compartment 37 is suppressed, the atmosphere around the vegetable compartment 57 and the storage compartment 59 does not become low in humidity, so that the drying inside the compartment is suppressed. Therefore, the vegetable room 57 can store vegetables and fruits under high humidity conditions in combination with the humidity control action of the humidity control means 58, and the storage room 59 can also be used for divisional management of fresh foods such as meat and fish that do not like drying. Then it is convenient.

It is discharged into. The discharged cool air cools the inside of the storage container 43 and then returns to the second cooling chamber 60. This cooling operation is performed until the temperature detector 64 is cooled to the set value. When the temperature reaches the set value, the compressor 66 and the second blower 62 are also stopped. Then, when the temperature rises to the set value, the compressor 66 and the second blower 62 are operated again, and thereafter, this operation is intermittently repeated, so that the inside of the freezing room 38 has a predetermined value (for example,-).
18 ° C.). As described above, the freezing compartment 38 is also cooled by the dedicated second evaporator 61 independently of the refrigerating compartment 37, and thus has a high storage temperature and a large storage load.

6, condenser 67, first decompressor 68, switching valve 69, second
Circulates through the decompressor 70 and the second evaporator 61, and the second evaporator 61 absorbs heat in the second cooling chamber 60 and expands and vaporizes. The vaporized refrigerant returns to the compressor 66, and this circulation operation is repeated, so that only the second evaporator 61 exerts a cooling operation. Therefore, the operation of the second blower 62 and the freezing room 3
8 alone is cooled, and the temperature sensor 64 in the freezer compartment drops to the set value and the compressor 66 and the second blower 62 stop, or the temperature sensor 63 in the refrigerator compartment rises to the set value. The process is continued until it is switched to the first refrigerant circuit 71 side.

得られる。This operation is repeated intermittently to keep the inside of the freezing room 38 cooled to a predetermined value (for example, -18 ° C.). In this way, the freezing compartment 38 also sets the second decompressor 70 to an appropriate amount of pressure reduction, so that the second chamber can be cooled independently during the second cooling.
The evaporator 61 can be set at a lower evaporating temperature, and the cooling capacity can be increased by lowering the cool air temperature. Therefore, a rise in the temperature of the food stored in the freezing compartment 38 can be suppressed, and stable storage quality can be obtained.

冷却効率が高まり電力消費を低減させることができる。As described above, the refrigerating room 37 is provided with the first evaporator 4.
5 and the first blower 46 and the freezer compartment 38 are provided with the second evaporator 6.
Since the first and second blowers 62 are cooled at a cool air temperature corresponding to the respective storage temperatures, the efficiency of the refrigeration cycle is increased by elevating the evaporation temperature particularly during cooling of the refrigerator compartment, and the cooling air passages are also provided in the respective compartments. Thus, the cooling efficiency is increased and the power consumption can be reduced.

よう構成して安価な二方弁を利用してもよい。In order to further increase the evaporating temperature of the first evaporator 45, the first decompressor 68 may be reduced in pressure and the second decompressor 70 may be decompressed in a larger amount. After reducing the amount of pressure reduction of the pressure reducer 68, another pressure reducer is added between the first evaporator 45 and the second evaporator 61 to lower the evaporation temperature of the second evaporator 61. Is also good. An appropriate combination and setting may be selected according to the target degree of the improvement of the efficiency of the refrigeration cycle and the improvement of the storage quality of food. Further, the switching valve 69 may be, for example, a three-way valve that selectively switches between the first refrigerant circuit 71 and the second refrigerant circuit 72. When the valve is opened, the valve almost flows to the first refrigerant circuit 71 due to a resistance difference. When closed, it may be configured to flow only to the second refrigerant circuit 72 side, and an inexpensive two-way valve may be used.
