題もあった。As described above, since the cooler is conventionally provided on the side of the freezer compartment having a low temperature, both the cool air supply duct to the refrigerating room having a high temperature and the cool air returning duct from the refrigerating room are provided. Since it has to be formed in the freezer compartment, there is a problem that the structure becomes complicated and the manufacturing cost rises. Also,
Since the freezing compartment having a low temperature and the refrigerating compartment having a high temperature are adjacent to each other with the partition wall in between, dew condensation easily occurs on the surface of the partition wall on the refrigerating compartment side due to the cooling action from the freezing compartment. Therefore, the partition wall is made thicker to improve the heat insulation performance between the two chambers, which causes a problem that the effective volume of the two chambers is reduced.

The temperature in B is maintained at an average of -3 ° C. In addition, since the first storage chamber 6A is cooled by the inflow of cold air (−3 ° C. or higher) after passing through the second storage chamber 6B having the relevant temperature, the temperature is higher than that of the second storage chamber 6B. The average temperature is about + 5 ° C.

Since the cold air has a relatively high temperature of about 0 ° C. to −5 ° C., the inside of the first storage chamber 6A is not overcooled. Further, since the blowing direction is directed to the surface of the heat insulating wall 5 on the side of the first storage chamber 6A as described above, the cool air blown from the auxiliary blower 53 is on the side of the first storage chamber 6A of the heat insulating wall 5. Flow along the surface. Therefore, it becomes possible to effectively eliminate the dew condensation on the surface of the heat insulating wall 5 on the side of the first storage chamber 6A due to the temperature difference between the two storage chambers 6A and 6B.

うになる。As described above in detail, according to the present invention, the cool air from the cooler is supplied to the second storage chamber having a low temperature through the duct, and the return cool air from the second storage chamber is thermally insulated. From the communication hole formed in the wall, it flows into the first storage chamber,
Since it returns to the cooling chamber through the suction port after passing through the storage chamber, the duct for returning cold air, which has been conventionally required, can be omitted. Further, since the first storage chamber is cooled to a higher temperature than the second storage chamber by the cold air flowing through the communication hole and passing through the second storage chamber, the structure of the cooling storage chamber is simplified and the manufacturing cost is reduced. And the effective volume of the first storage chamber can be increased by reducing the number of ducts.

Therefore, by operating this auxiliary blower to supply the cool air in the duct directly to the first storage chamber, it is possible to achieve the accurate temperature control of the first storage chamber.

とが可能となるものである。In particular, the temperature of this cold air is relatively high due to the heat generated by the operation of the auxiliary blower, so that the first storage chamber is not overcooled, and the blowing direction is the first direction of the heat insulating wall. Since it is directed to the surface on the side of the storage chamber, the cold air blown out from the auxiliary blower flows along the surface on the side of the first storage chamber of the heat insulating wall. Therefore, it becomes possible to effectively eliminate the dew condensation on the surface of the heat insulating wall on the first storage chamber side due to the temperature difference between the two storage chambers, thereby reducing the thickness of the heat insulating wall and reducing the thickness of the two storage chambers. It is possible to increase the effective volume.
