In addition, cold air flowing into the refrigerator compartment 15 flows in from a plurality of cold air vents 43 formed between the shelves 42 through the duct 41 provided on the back surface thereof. The inflow of cold air is controlled by controlling the opening and closing of the damper device 45 installed on the lower part of the back of the refrigerating chamber 15 to adjust the temperature in the refrigerating chamber 15 . And the cold air which has cooled the inside of the refrigerator compartment 15 is reintroduced into the vegetable compartment 19, and is returned to the cooler 39 after that.

Fig. 3 is an enlarged perspective view with the storage container 31 of the second freezer compartment removed. In addition, in order to show the relationship between the movable rail 47 and the pulley 49 in detail, the figure shows the situation after the stopper 61 is removed. A pair of movable rails 47 extend left and right along the drawing direction on the back side of the door 23b, and a pair of pulleys 49 arranged on the front part of the inner box 5 side wall below the freezer compartment 17 are fixed pulleys. It is placed on the concave portion 47a formed on the movable rail 47 to control the direction in which the door is pulled out. 51 is a movable pulley arranged on the movable rail rear end portion 47b, which can slide in the U-shaped fixed rail 53 installed on the inner box side wall.

At this time, the container 31 is housed in the space formed by the door 23b, the left and right movable rails 47, and the stopper 61 (as shown in FIG. 4(B)) installed on the left and right movable rail rear ends 47b, The storage container 31 and the door 23b can be pulled out integrally by placing the bottom surface of the storage container 31 on the L-shaped receiving portion 59 protruding toward the space.

When the door 23b is drawn out, food or the like is put in from the upper opening 31a of the storage container to cool (in this embodiment, freezing), and the actual storage volume becomes the volume of the storage container.

In this embodiment, since the bottom surface of the container 31 is supported by the receiving portion 59, compared with the conventional support on the upper flange portion of the container, the inclined portion 63 of the container 31 can be made close to the side wall of the freezer. On the one hand, the width of the lower portion (b in FIG. 5 ) can be shortened to increase the storage capacity.

In addition, since it is not necessary to ensure the strength of the flange portion 57 by supporting the bottom surface of the container 31 with the movable rail 47, the dimensions of the flat portion 57a and the hanging portion 57b of the flange portion can be shortened so that the width dimension of the flange portion ( The a) in Fig. 5 is shortened, so that the volume of the container can be increased and the molding can be simplified.

Since the storage container 31 is provided to be detachable, when the storage container 31 is drawn out, the storage container 31 is lifted up after the door 23b is drawn out until the movable pulley 51 comes into contact with the stopper 65 . At this time, it is necessary to incline the storage container 31 for the periphery of the opening 31a of the storage container 31 does not collide with the partition plate 29. However, in this embodiment, since the movable rail 47 is arranged on the lower part of the storage room, The housing container 31 can be easily tilted. Therefore, the storage container can be easily attached and detached, and the cleanability is good.

Ribs 67 protruding into the space between the pair of left and right receiving parts 59 formed on the movable rail 47 are formed on the inside of the bottom surface of the container 31 to not only position the container 31 but also strengthen the container 31.

For the 2nd freezer compartment 17b as shown in the present embodiment, in the occasion that there is partition plate 13 at the bottom, after casing 9 is formed, filling in inner panel 13b, partition front surface 13a and non-illustrated vegetable compartment top plate The partition plate 13 formed by the heat insulating material 7 is installed separately as a single unit. As shown in FIG. 6 , the inner plate 13b (the bottom plate of the freezer compartment in this embodiment) and the fixed rail 13c can be integrated.

According to the above-mentioned structure, it is possible to reduce the screw connection space and manufacturing man-hours, reduce the cost, and prevent the occurrence of excessive fluctuations in manufacturing quality.

In addition, although this Example demonstrated using the 2nd freezer compartment, it is applicable also to a vegetable compartment and a 1st freezer compartment.

In addition, as for the structure in which the bottom surface of the storage container is supported by the movable rail, the stepped forming portion 71 may be formed as shown in FIG. 7 and placed on the movable rail.

In addition, as shown in FIG. 8, ribs (69 in the figure) formed on the lower side of the storage container may be used as supporting parts and placed on the movable rails.

In summary, the present invention has the advantage of expanding the overall width of the storage container and increasing the storage volume because the movable rail is disposed at the corner below the side wall of the freezing chamber in the depth direction and the container is supported by the bottom. At the same time, it has the effect of simplifying the forming and making the appearance more beautiful.

In addition, by integrating the fixed rail portion and the bottom plate, the cost can be reduced, the space for screwing and manufacturing man-hours can be reduced, and excessive fluctuations in manufacturing quality can be prevented.
