Reference numeral 20 denotes a cooling air circulation fan provided above the cooler 8, and reference numeral 21 denotes a fan motor. As shown in FIG. 1, the cooler 8 and the cool air circulation fan 20
It is located on the back of the refrigerator body 1.

Therefore, in the compressor 6 in which the lower surface of the freezing compartment 9 has an upper bottom, the position of the cooling air circulation fan 20 is higher than the upper surface of the freezing compartment 9 (the lower surface of the partition wall 22). It will be located above.

Reference numeral 22 denotes a partition wall as described above. The partition wall 22 thermally divides the space between the freezing room 9 and the vegetable room 10. The partition wall 22 has a rising portion 22a at the rear. This rising amount is a height reaching the upper portion of the cool air circulation fan 20.

Further, the partition wall 22 forms the upper surface of the freezing compartment 9 as described above. In other words, the partition wall 22 also forms the receiving surfaces of the gaskets (not shown) of the doors 13 and 14. Therefore, at the front end of the partition wall 22, there is provided a high-temperature pipe 24 (meaning a pipe of a condenser part of a refrigeration cycle) for heating the surface of the partition plate 23 so as not to be exposed to dew. I have. This partition plate 23

Then, the first partition wall 22b is assembled to the refrigerator box 5 before foaming of the foamed heat insulating material 4. This is for attaching the high-temperature pipe 23 to the back surface of the partition plate 23. That is, the high-temperature pipe 23 is provided on most of the opening front surface of the box 5 of the refrigerator, and the high-temperature pipe 23 is a part thereof.

Therefore, it goes without saying that the first partition wall 22b may be a beam-shaped partition wall to which the high-temperature pipe 23 can be attached.

The second partition wall 22c is assembled to the box body 5 after foaming. That is, as shown in the figure, in a refrigerator in which the frontage of the freezing compartment 9 is divided into two by the third partition wall 28, the cooler 8, the cool air circulation fan 20, and the fan motor described above are used. 21
After the foaming of the heat insulating material 4, the partition wall 22 and the third partition wall 28
It is easy to guess that it is almost impossible to assemble through (within 30 cm). That is, the position of the eyes of the person who installs the cooler 8 and the cool air circulation fan 20 in the box 5 (the refrigerator body 1) is as shown in the figure. Therefore, in order to assist this work, the rising portion 22
The second partition wall 22c having a is to be assembled to the refrigerator body 1 at the end of the assembling of the cooler 8 after foaming.

In other words, the size of the second partition wall 22c is large enough to put the cooler 8 in and out when the cooler 8 is assembled to the cooler room 19, and large enough to allow the work of assembling the cooler 8 and the like. It is something to keep.

Thus, the damper assembly 32 has the protruding wall 2
The cold air passage formed in the heat insulating material on the side of the damper assembly 32 just before is mounted on the molded heat insulating material 30.
Is communicated with the cold air passage 31 formed at the bottom.

Therefore, the cool air from the cooling chamber 19 that has passed through the cooler 8 reaches the damper assembly 32 via the protruding wall 30, and only a necessary amount of the cool air is actuated by the damper. 11 or the like.

Reference numeral 18 denotes a drawer container for a vegetable room. As shown in the figure, the drawer container 18 for the vegetable room has a protruding wall 29 as shown in FIG.
In addition, the rising portion 22a of the partition wall 22 is cut away so as to travel to the vegetable room 10 side.

The drawer container provided in the refrigerator, such as the drawer container 18 for the vegetable room, is special (double rail).
Normally, the refrigerator opening surface (partition plate 23
Surface), only the 2/3 position of the container 18 can be pulled out without the whole projecting out. This is due to the structure of the frame 33 and the rail from which the drawer container 18 is drawn. Therefore, the drawer container 18 does not need to be deep enough to come into contact with the protruding wall 29 and the rising portion 22a.

In other words, the current refrigerator has an invalid space at the rear of the drawer container 18. In the present application, the damper assembly 32 is installed in order to use the invalid space.

Numeral 41 denotes a refrigerator compartment duct for supplying cool air from the damper assembly 32 to the refrigerator compartment 11. From this duct 41, cool air is blown out to the refrigerator compartment 11 as shown in the figure.

Although not shown in the figure, b is mounted in a guide groove formed in the inner box 3 by sliding it from the front side into a guide groove, which is conventionally employed.

Numeral 34 denotes guide holes for screwing provided on both side ends of the second partition wall 22c, and numeral 35 denotes a step formed on the side wall of the inner box 3 for mounting the partition wall. Using the step 35, the second partition wall 22c is screwed with the screw 36.

That is, the back of the second partition wall 22c is
As shown in FIG. 1, it is attached to the protruding wall, and both sides are
The front portion is assembled to the first partition wall 22b as shown in FIG.

As is apparent from the figure, the second partition wall 22
When the cooling device 8 and the cooling air circulating fan 20 are completely assembled in the cooling device room 19, the device c is mounted in a manner such that a lid is placed from above. Of course, a sealing material for preventing cold air and water leakage is applied to the step portion 35 and the protruding wall 29 that are in contact with the second partition wall 22c, and to the contact portion with the first partition wall 22b. That is natural.
As means for facilitating the attachment of the sealing material, as shown in FIG. 6, the second partitioning wall 22c is formed in a container shape, and a flange 37 is provided on an end surface thereof. A sealing material (for example, soft urethane) is provided on the back surface of the flange 37. Form, etc.).

Of course, at this time, it is needless to say that the inner box 3, the protruding wall 29, and the first partition wall 22b, which are the receiving surfaces, also need to correspond to each other.

5 has a cool air passage 43 connected thereto.

Reference numeral 47 denotes an electric component box (for example, housing a board or the like), which is incorporated in the case 40.

Next, the relationship between the cool air cooled by the cooler 8 and the damper assembly 32 will be described. In FIG. 5, among the cool air forcedly circulated by the cool air circulation fan 20, the cool air blown out to the freezing room 9 is discharged to the discharge ports 48 and 4.
The air is blown into the freezing compartment 9 through the fan guard 25 (FIG. 1) from the fan 9 and returns to the cooler 8 from the lower part of the fan guard 25.

On the other hand, the cool air blown out to the refrigerator compartment 11 enters the cool air passage 42 of the damper assembly 32 through the cool air passage 31 formed in the protruding wall 29, and the electric damper 38.
As shown in FIG. 1, the amount of cold air controlled by the above is blown out from the refrigerator compartment duct 41 to the refrigerator compartment 11 as shown in FIG.

Further, the cool air after cooling the refrigerator compartment 11 passes through the cool air passage 43 provided in the damper assembly 32, and projects to the inside of the refrigerator so as to be continuous with the projecting wall 29. It is returned to the lower part of the cooler 8 through a return duct 45 provided in the wall 44. At this time, vegetable room 1
