As shown in FIG. 11, the inside of the refrigerator is divided into two left and right storage rooms 2A and 2B by a heat insulating wall 1, and a cooler 3 and a first cooling fan 4A face the left storage room 2A. At the same time, a second cooling fan 4B is provided in the right storage room 2B.
The cooling air generated by the cooler 3 is circulated and supplied to the left storage room 2A by the first cooling fan 4A, and the left storage room is driven by the second cooling fan 4B. Part of the cool air in the chamber 2A is sucked from the suction duct 5 and circulated and supplied to the right storage chamber 2B. Then, for the left storage room 2A, the cooler 3 and the first cooling fan 4A are simultaneously turned on and off to maintain the set temperature, and for the right storage room 2B, the second cooling fan 4B is turned on and off. By controlling, another set temperature higher than the set temperature of the left storage room 2A is maintained.

に、温度帯が重なる部分ができて、芳しくない。In the above-mentioned conventional structure, the two chambers 2A, 2A,
It is good if there is a large difference between the set temperatures of 2B. For example, ice cream whose storage suitable temperature is slightly different
A, 2B, as in the case of storing separately,
If the difference between the set temperatures of B is relatively small, there is a considerable problem. That is, when the storage room is maintained at the set temperature, the room temperature is actually changed to a sine curve shape which raises and lowers the set temperature by repeatedly supplying and stopping the cool air,
Thereby, it is regarded as being at the set temperature. In particular, in the conventional type, temperature control is mainly performed based on the on / off of the cooling fan.Specifically, when the room temperature reaches the upper limit temperature exceeding the set temperature by a certain temperature, the cooling fan is turned on and the set temperature is set to a certain temperature. When the temperature falls below the lower limit temperature, the cooling fan is turned off, and the temperature difference between the heights of the temperature curve becomes relatively large. Therefore, as described above, both storage rooms 2
If the difference between the set temperatures A and 2B is small, as shown in FIG. 12, a portion where the temperature zones overlap is formed, which is not good.

のであって、その目的は、簡単な構造でもって室温の微
調整が行えるようにするところにある。In order to avoid this, it is conceivable to set the upper and lower limit temperatures at which the cooling fan is turned on and off to a temperature very close to the set temperature, and to finely control the cooling fan on and off. However, chattering may occur. It is not practical. It is also conceivable to provide a cooling fan with a small capacity in advance, but in this case, both storage rooms 2
In the case where the difference between the set temperatures of A and 2B is large and there is no need to worry about the overlapping of the temperature zones, for example, the supply of cool air is delayed and the temperature recovery is delayed. There is a problem that a cooling fan having a different capacity is required depending on the difference between the set temperatures of 2B. The present invention has been completed based on the above circumstances, and an object of the present invention is to enable fine adjustment of room temperature with a simple structure.

When the room temperature thermistor 28B detects that the room temperature of B has dropped to “−10−α ° C.” (lower limit temperature), the right cooling fan 26B stops. Thereafter, the temperature of the right storage room 12B rises, and when the temperature reaches “−10 + α ° C.” (upper limit temperature), the right cooling 26B is driven. Then, even when the compressor 18 is operating, as well as when it is stopped, the cooler room 16 is in a low-temperature atmosphere, so that cool air is circulated and supplied to the right storage room 12B to be cooled again. Right storage room 12
In B, after that, when the room temperature falls to the lower limit temperature, the right cooling fan 26B stops, and when the room temperature rises to the upper limit temperature, the right cooling fan 26B is driven and the cool air is circulated and supplied, and the room temperature is set.

Thereafter, when the temperature of the left storage room 12A rises and reaches “−15 ° C. + α ° C.” (upper limit temperature), the compressor 18 and the left cooling fan 26A are driven.

ある。Here, for example, both suction ducts 27A, 27
When the expansion device 30 of B is in the fully opened state, the temperature of the storage chambers 12A and 12B tends to be abrupt due to a large amount of circulation of the cool air, and therefore, the supply of the cool air is detected by detecting the upper limit temperature and the lower limit temperature. Even if the stop is controlled, the temperature actually fluctuates in a sine curve between a temperature significantly higher than and lower than the limit temperature. That is, if the temperature difference between the heights in the temperature curve is large and the difference between the set temperatures of the two storage chambers 12A and 12B is as small as “5 ° C.” as in this embodiment, the temperature zones may overlap.

Also, when the supply of cold air and the stop thereof are controlled, as shown in FIG.
The temperature changes in the storage chambers 12A and 12B become gradual, and the actual room temperature is kept close to the upper limit temperature and the lower limit temperature, that is, the temperature difference between the high and low levels is kept small. As a result, the difference between the set temperatures of the two storage rooms 12A and 12B is “5”.

Thus, even when the difference between the set temperatures in the left and right storage chambers 12A and 12B is small, the temperature zones can be clearly distinguished and controlled without overlapping. When there is no difference between the set temperatures in the two storage chambers 12A and 12B and there is no possibility that the temperature zones overlap, the throttle device 30 is fully opened to obtain a large amount of circulating cold air, and the speed of the temperature recovery is prioritized.

Further, since it is a so-called manual type, even if it is used in an ultra-low temperature atmosphere such as “−40 ° C.”, there is little possibility of failure. In addition,
The guide groove 34 of the diaphragm device 30 is preferably provided with a scale 35 of the tilt angle of the shutter 31. If the aperture ratio is also displayed, it is easier to use.

る。In this embodiment, the lower end of the intermediate wall 11 communicates with the bottom of the two storage chambers 12A and 12B.
Is open. Therefore, for example, even when the heat-insulating door of the right storage room 12B on the high-temperature side is frequently opened and the temperature inside the refrigerator increases, the cool air of the left storage room 12A on the low-temperature side is sucked in through the communication hole 36, and the right storage room is stored. The temperature of the chamber 12B is quickly restored. In detail, the bottom of the right storage room 12B is cooled by the cool air sucked from the communication hole 36, and the right cool air duct 27B and the right cool air are sucked while the sucked cool air flows from the right suction duct 27B to the cooler room 16. Heat exchange occurs with the storage room 12B, and the inside of the right storage room 12B is effectively cooled. In addition, since the air that has been cooled to some extent is returned to the cooler 17 side, the cooler 17 can generate cool air in a short time and supply it to the right storage room 12B. With this, the speed of returning the temperature of the right storage room 12B is greatly increased.

通化でき、構造が簡略化できる。As described above, the cooler 17 is in a state where cold air which has been cooled to a certain degree is sent to the cooler 17, that is, the load on the cooler 17 is reduced. Therefore, it is possible to prevent the liquid back phenomenon from occurring due to a sudden increase in the load of the cooler 17. In addition, the left storage room 12A on the low temperature side also
When the temperature inside the refrigerator rises to a level higher than that of the right storage room 12B, the cool air in the right storage room 12B
Suctioned through 6 also speeds up the temperature return. Further, since the bottoms of the two storage chambers 12A and 12B are communicated with each other, the body drain port 37 can be shared by the two chambers 12A and 12B, and the structure can be simplified.
