On the other hand, when the control plate 63 opens the cool air variable amount supply passage 43B, the cool air supply to the vegetable compartment 4 is performed by the cool air supply from the cool air variable amount supply passage 43B in addition to the cool air supplied from the cool air constant amount supply passage 43A. As a result, the temperature of the vegetable room 4 is set to a relatively low temperature state of about 3 ° C. on average.
[0031]
In the system in which the control plate 63 increases or decreases the supply cool air amount passing through the cool air variable amount supply passage 43B, if the control plate 63 decreases the supply cool air amount through the cool air variable amount supply passage 43B by operating the operation lever 62, the vegetable room 4 The supply of cool air to the chiller is performed by reducing the amount of cool air from the cool air variable amount supply passage 43B and supplying the cool air mainly from the constant cool air supply passage 43A. It will be in the normal storage temperature state. On the other hand, when the control plate 63 increases the amount of cool air supplied through the cool air variable amount supply passage 43B, the cool air supply to the vegetable compartment 4 is performed in addition to the cool air supplied from the cool air constant amount supply passage 43A and from the cool air variable amount supply passage 43B. The increased supply of cold air is performed, and the temperature of the vegetable compartment 4 becomes a relatively low temperature state of about 3 ° C. on average.
[0032]
The temperature of the vegetable compartment 4 can be switched in a plurality of stages in addition to the two types of switching as described above. However, in actual use, the temperature of the vegetable compartment 4 is switched between too many temperature zones. Since there is no need to perform the above, two kinds of switching as described above are sufficient.

[0033]
Thereby, the articles stored in the refrigerator compartment 3 are not obstructed, and the operation from the refrigerator compartment 3 is easy. When the vegetable container 15 is drawn out together with the vegetable compartment door 11, it becomes difficult to provide the operation lever 62 in the vegetable compartment 4, but this problem is also solved. Further, the effective storage volume of the vegetable compartment 4 does not decrease when the operation lever 62 is provided in the vegetable compartment 4, and the vegetable container 15 having a large capacity can be provided.
[0034]
By the cool air passage control device 60 of the present invention, the temperature of the vegetable room 4 is switched between a relatively high temperature state of about 5 ° C. on average and a relatively low temperature state of about 3 ° C. on average, as in the conventional temperature state. it can. Therefore, by setting one of the cool air passages 43A and 43B as a cool air constant supply passage and the cool air passage 43B as a cool air variable amount supply passage, the vegetable room 4 can be switched to two different temperatures. Therefore, the refrigerator can be economically operated without cooling the vegetable compartment continuously or unnecessarily for a long time to a low temperature state.
[0035]
In addition, the present invention is not limited to the refrigerator of the above-described embodiment, and can be applied to various types of refrigerators, and various changes can be made without departing from the technical scope of the present invention. Is what you do.
