In the casing 141 as shown in FIG.
The discharged cool air is formed in the intermediate wall 30 in a diffuser shape so as to be evenly distributed over the entire surface of the evaporator 11. At this time, the fans 110 and 12 are installed in the casings 141 and 142 so as to be freely rotatable.
0 is formed by a centrifugal fan having a mountain-shaped side section, but the upper and lower fans 110 and 120 are installed so as to be vertically symmetric with respect to the motor 130.

The compressor 59 is driven by a signal from the control unit, and sends the compressed cool air to each of the evaporators 11 and 21. The evaporators 11 and 12
1 is discharged into the freezer compartment 10 through the discharge port 15 in the freezer compartment 10, and the cold air is exchanged with the cold compartment 20.
In accordance with the temperature condition of the refrigerator compartment 20, the refrigerator compartment 2 through the discharge port 25 via the opened damper 23

て、冷気誘導路31に誘導する。In the freezer compartment 10, the low-temperature cold air that has passed through the discharge port 15 exchanges heat with food and drink stored in the freezer compartment 10, and then reaches the vicinity of the cool air circulation device 100.
It changes to relatively high temperature cold air. The centrifugal fan 110 rotated by the fan motor 130 smoothly draws in the cool air whose temperature has increased and the density has decreased, and at the same time, guides the cool air into the cool air guide path 31 by the casing 141 surrounding the centrifugal fan 110.

誘導路32に誘導する。On the other hand, in the refrigerating compartment 20, the low-temperature cold air passing through the discharge port 25 exchanges heat with food and drink stored in the refrigerating compartment 20, similarly to the progress of the cold air in the freezing compartment 10. Then, the air reaches the vicinity of the cool air circulation device 100 and is converted into relatively high-temperature cool air. The centrifugal fan 120 rotated by the fan motor 130 smoothly draws in the cool air whose temperature has increased and the density has decreased, and at the same time, guides the cool air into the cool air guide path 32 by the casing 142 surrounding the centrifugal fan 120.

高さを異ならしめて、対応せしめたものである。That is, since the temperature of the cool air passing through the upper fan 110 is lower than the temperature of the cool air passing through the lower fan 120, the density is relatively low. This difference in temperature is made to correspond by changing the heights of the fans 110 and 120 as shown in FIG.

きる。The cool air guided to each of the cool air guide paths 31 and 32 travels along the diffuser type cool air guide paths 31 and 32 whose width increases as they advance, and then, at the end portions thereof, each evaporator. It comes into contact with the suction portions 11 and 21. Thus, the cold air in each of the chambers 10 and 20 can independently advance to the evaporators 11 and 21 without being mixed with each other.

れるものである。At this time, if the cool air reaches the suction sections of the evaporators 11 and 21 while diffusing while traveling along the diffuser type cool air guide paths 31 and 32, the cool air passes through the entire surface of the suction sections and is evaporated. Even if frost is formed by flowing into the vessels 11 and 21, the frost can be formed on the entire surface of the suction portion. The cool air that has passed through the evaporators 11 and 21 is further discharged to the freezing compartment 10 and the refrigerating compartment 20, respectively.

By driving the centrifugal fans, power consumption can be reduced, and further, by forming the evaporator cover so as to be in contact with each evaporator, the internal volume of each chamber can be increased.
