The cooling chamber 22 communicates with the refrigerating and freezing chamber 24 through the air passage 23, and the cooling fan 25 sends the cooled airflow in the cooling chamber 22 to the refrigerating and freezing chamber 24. The heat exchanger 20 includes a large number of fins 2 arranged in parallel.

霜を充分に防ぐことができなかった。The airflow 29 is blown into the cooling chamber 22 from the lower central part of the heat exchanger 20 and comes into contact with each part of the heat exchanger 20 to be cooled. There is moisture contained in the freezer compartment 24, and the moisture becomes frost and adheres to the heat exchanger 20. In many cases, the frost forms a lump or a bridge and partially adheres to the fin 26 and the refrigerant pipe 27. The frost that forms in the form of lumps or bridges is larger than the frost that adheres to the surfaces of the fins 26 and the refrigerant tubes 27, so even if defrost heating is performed, the frost is not uniformly defrosted, Finally, it becomes a cause of deteriorating the cooling efficiency of the heat exchanger 20. Fin 2
In order to prevent the block-like frost formation and the bridge-like frost formation, as shown in FIG. 6, there are some through holes 28 including the end portions. Bridge-shaped frost could not be sufficiently prevented.

く抑制することができる。The heat exchanger configured as described above will be described in detail below. When a refrigerating cycle (not shown) operates and enters a cooling operation state, an airflow cooled by a cooling fan 9 is sent to a refrigerating compartment or the like to become a moist airflow in the refrigerator or the like, and an airflow path for guiding the airflow 6. An air flow containing water returns to the upper side portion 5 of the heat exchanger 1 through 7. The returned airflow 6 enters the lower part of the heat exchanger 1 and the gap 15 between the heat exchanger 1 and the partition plate 12 so that it can be blown in, so that the heat exchanger 1 is introduced from the upper side part 5 on the side where the airflow enters.
Around the center of the fin 2 evenly around the edges of the fins 2 and the refrigerant pipes 3.
It becomes frost and adheres to the surface of. On the other hand, since the upper side portion 5 of the heat exchanger 1 on the inflow side of the air flow 6 is inclined with the inclination angle 8, the surplus portion is left on the lower side portion 14 on the other side of the heat exchanger 1 and the bent portion 4 of the refrigerant pipe. Since a large amount of liquid refrigerant accumulates, due to the influence of the diffusion phenomenon of the air flow, frost is evenly adhered to the edges of the fins 2 and the surface of the refrigerant pipe 3 from the vicinity of the center of the heat exchanger 1 to the lower side portion 14. . Since frost is formed due to the above-described effect, the heat exchanger 1 is less likely to form lumpy frost over time, and therefore the performance is not significantly deteriorated. Then, the defrosting heater 1 is arranged at regular time intervals.
If defrosting is performed by energizing No. 3, the temperature rise in the refrigerator can be suppressed to a low level.

In addition, since the temperature rise in the refrigerator can be suppressed to a low level, it has a great effect on energy saving.

できる。FIG. 3 is a simplified schematic view of the refrigerator according to the second embodiment of the present invention. In FIG. 3, cooled airflows are sent to a plurality of refrigerating chambers and become airflows containing moisture in the refrigerators and the like, and heat exchangers are passed through air passages 7 and 16 that guide the airflows without converging the airflows at one location. Air flow containing water returns from both sides of 1. Of the returning airflow,
The large air flow 6a having the larger air flow rate enters the lower portion of the upper side portion 5 which is inclined upward so that the large air flow 6a is easily blown into the heat exchanger 1.
And into the gap 15 of the partition plate 12. By inclining the heat exchanger 1, an inclination angle 8 is formed. From the upper side portion 5 to the vicinity of the center of the heat exchanger 1, the edges of the fins 2 and the refrigerant pipes 3
Frost adheres evenly to the surface of. On the other hand, the lower side portion 1 of the heat exchanger 1, which is the inflow side of the small air flow 6b having the smaller air flow rate.
In particular, since excess liquid refrigerant accumulates in the bent portion 4 of the refrigerant pipe 3, the large-volume airflow 6a diffuses and the other small-volume airflow 6b blows into the lower-side portion 14, so that heat exchange from the lower-side portion 14 occurs. Frost uniformly adheres to the edges of the fins 2 and the surface of the refrigerant pipes 3 near the center of the container 1. Since frost is formed by this effect, the heat exchanger 1 is less likely to have lumpy frost and the like due to the passage of time, and therefore is not significantly deteriorated in performance. Then, if the defrosting heater 13 is energized at regular time intervals to defrost, the temperature rise in the refrigerator can be suppressed to a low level.

省エネルギーへの効果も大きい。As described above, in the refrigerator according to the second embodiment, even if there are many refrigerating chambers or freezing chambers and there are many temperature zones, the air passages do not join in one place, and the large air flow 6a and the small air flow 6b are not merged.
It can be divided into the air passages 7 and 16. Therefore, in addition to preventing the air passage from becoming complicated due to air passage crossing, etc., and not only preventing a sudden decrease in the heat exchange efficiency of the heat exchanger due to massive frost formation,
Since the temperature rise inside the refrigerator can be suppressed to a low level, it has a great effect on energy saving.

昇を低く抑制することができる。As described above, according to the present invention, frost is formed by blowing the air stream from the upper side of the inclined heat exchanger, and the bent portion of the refrigerant pipe on the lower side of the heat exchanger. The liquid refrigerant is forcibly stored in the heat exchanger, and the heat exchanger is uniformly frosted by the effect of frost formation due to airflow diffusion to prevent lumpy frost formation and prevent significant deterioration of the heat exchanger efficiency. It is possible to suppress the energy saving effect due to the reduction of the temperature and the rise in the temperature inside the refrigerator to a low level.

の高効率化が図れる。Further, frost caused by blowing in a large amount of air with a large air flow rate from the upper side of the heat exchanger and the liquid refrigerant on the lower side of the other side of the heat exchanger are forced into the refrigerant pipe and its bend. It is possible to prevent partial blocky frost formation and to prevent significant deterioration of the efficiency of the heat exchanger by uniformly frosting the heat exchanger due to the effect of frosting that is accumulated in the The energy saving effect due to the shortening of the defrosting time and the temperature rise in the refrigerator can be suppressed to a low level. Moreover, since the airflow is not taken in only one direction at the lower part of the heat exchanger, it is not necessary to join the airflow in one place even in the return air passage of the refrigerating room having a plurality of temperature zones such as a specific temperature room, so that the crossing can be performed. It is possible to design an air passage that does not require high efficiency such as increasing the internal volume.
