In the refrigerator that circulates the cool air from the refrigerator to the refrigerating compartment and the vegetable compartment, cools each compartment, and then circulates it back to the cooler, the duct extends outward from the refrigerating compartment of the inner box to the vegetable compartment. A first heat insulating plate having a bulged groove and a cold air intake installed on the front surface thereof, a second heat insulating plate having a cold air outlet installed on the front surface of the first heat insulating plate, and the second heat insulating member. And a cover mounted on the front surface of the plate to send a part of the cool air from the cooler to the refrigerating chamber through the cool air outlet of the second heat insulating plate and the cool air intake port of the first heat insulating plate. Through the groove to the vegetable compartment.

[0005]

[Action]

 According to the above structure, the duct for guiding the cool air to the vegetable compartment is provided in the inner box to reduce the volume of the duct and increase the effective volume of the refrigerating compartment.

【Example】

 Embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, those having the same functions as those in FIG. 6 are designated by the same reference numerals, and detailed description thereof will be omitted. As shown in FIGS. 1 and 2, the first heat insulating plate 14 is fitted into the concave portion formed by bulging the inner box 13 in the deep part of the refrigerating chamber 3 so as to face the first heat insulating plate 14. A second heat insulating plate 15 is additionally provided, and the two heat insulating plates 14 and 15 form a duct 16 that guides cool air from the cooling chamber 8. Then, the cover 17 is attached so as to cover the left side portion of the second heat insulating plate 15, and the internal components such as the heat insulating plate are covered so as not to be seen by the user. On the other hand, the inner box 13 on the right side of the first heat insulating plate 14 is further expanded to form a groove 18 leading from the refrigerating compartment 3 to the vegetable compartment 4, and a part of the cool air flowing from the upper part of the duct 16 is formed into the groove 18. It leads to the vegetable room 4 through. As shown in FIG. 3, the first heat insulating plate 14 is formed of a rectangular styrofoam material or the like, and has a cold air intake 20 for taking in cold air to the vegetable compartment 4 in the center. As shown in FIG. 4, the second heat insulating plate 15 is formed of a styrofoam material, has a box shape with an upper opening, and is provided with a plurality of cool air outlets 3a on a flat surface portion. As shown in FIG. 5, the cover 17 is formed in a U-shape, and the front surface is provided with the cool air outlet 3a corresponding to the cold air outlet 3a of the second heat insulating plate 15. In the above structure, the cold air cooled in the cooling chamber 8 enters the duct 16 and is guided by the duct 16 and part of the cold air is delivered to the refrigerating chamber 3 from the cold air outlet 3a. The remaining cool air is delivered from the cool air intake 20 to the groove 18, the delivered cool air is guided by the groove 18, reaches the upper part of the vegetable compartment 4, and is delivered to the vegetable compartment 4 from the cold air outlet 4a.
