a, 9b and drawer containers 16, 17 and vegetable compartment 1
0 is provided on the door side with a frame 33 (shown by a broken line). In other words, doors 12, 13,
Reference numeral 14 denotes a drawer-type door from which the drawer containers 16, 17, and 18 are pulled out in accordance with the drawer of the door.

The present refrigerator is also characterized in that the freezing room 9 is the lowest stage, the center is a vegetable room 10, and the refrigerator room 11 is above it.

Thus, the refrigerator main body 1 includes the compressor 6
The rear part of the freezer compartment 9 has an upper bottom in comparison with the front part. Accordingly, the drawer container 16 of the freezing compartment 9a is formed in a shape avoiding this portion.

Reference numeral 19 denotes a cooler room formed at the rear rear portion of the freezing room 9. In the cooler room 19, the cooler 8 is stored upright.

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 in which the lower surface of the freezing room 9 has an upper bottom by the compressor 6, the position of the cooling air circulation fan 20 is higher than the upper surface of the freezing room 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. . Based on the partition plate 23, the rising portion 22a is rising upward.

Reference numeral 25 denotes a fan guard which also serves as a partition between the cooler room 19 and the freezing room 9. The cool air cooled by the cooler 8 is transferred to the freezing room 9 by the operation of the cool air circulation fan 20. It is blown out via the guard 25.

26 is an ice tray. This ice tray 26
It is provided near the lower surface of the partition wall 22. Reference numeral 27 denotes a cool air duct for sending cool air to the ice tray 26, which is attached to the lower surface of the partition wall 22 as shown in FIG.
The space between the lower surface 2 and the cool air duct 27 is a cool air passage.

The partition wall 22 is divided into a side having a rising portion 22a (a second partition wall 22c) and a side having a partition plate 23 (a first partition wall 22b). 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 24 to the back surface of the partition plate 23. That is, the high-temperature pipe 24 is provided on most of the opening front surface of the box 5 of the refrigerator, and the high-temperature pipe 24 is a part of the high-temperature pipe 24.

Therefore, it is needless to say that the first partition wall 22b may be a beam-shaped partition wall to which the high-temperature pipe 24 can be attached.

The second partition wall 22c is assembled to the box 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 into the cooler room 19, and large enough to allow the work of assembling the cooler 8 and the like. It is something to keep.

Reference numeral 29 denotes a protruding wall. The protruding wall 29 and the partition wall 22 (the rising portion 22a) described above form an upper portion of the cooler room 19. Also, in this protruding wall 29,
A molded heat insulating material (styrofoam) 30 is provided before filling the foamed heat insulating material 4, and is adhered and fixed by the foamed heat insulating material 4.

Reference numeral 31 denotes the molded heat insulating material 30 and the protruding wall 29.
2 shows a cold air passage formed through the air passage. One side of the partition wall 22 described above is attached to the protruding wall 29 with a structure as shown in the figure.

Reference numeral 32 denotes a damper assembly. The damper assembly 32 is composed of a heat insulating material or the like having an electric damper described later and a cool air passage.

Thus, the damper assembly 32 has the protruding wall 2
9 and the cold air passage formed in the heat insulating material on the side of the damper assembly 32 just before is formed into the heat insulating material 3.
It is in communication with a cold air passage 31 formed at zero.

Accordingly, the cool air from inside 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 operated 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 compartment, is special (double rail).
Refrigerator opening surface (23 partitions)
Only 2/3 of the container 18 can be pulled out without the whole projecting. This is a frame 33 for pulling out the drawer container 18.
And the structure of the rail. 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 ineffective 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.

Next, the structure and the mounting structure of the partition wall 22 will be described with reference to FIGS. 2, 3 and 4. As described above, the partition wall 22 is formed by the first partition wall 22b.
And a second partition wall 22c. The connecting portion is configured as shown in FIGS. 2 and 4, and is devised so that water, cold air, etc., do not leak from the joint.

The connection between the second partition wall 22c and the inner box 3 is configured as shown in FIG. In addition, the first partition wall 22
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 is a screw tightening guide hole provided at both ends with respect to the second partition wall 22c.
Is a step formed on the side wall for mounting the partition wall. Utilizing this step 35, the second partition wall 22c is connected to the screw 3
It is screwed at 6.

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
The front portion is assembled to the first partition wall 22b as shown in FIG.

As is clear 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 serving as the receiving surface, the protruding wall 29, and the first partition wall 22b also need to correspond to each other.

Next, the relationship between the damper assembly 32 attached to the upper surface of the protruding wall 29 and the cooler room 19 formed below the damper assembly 32 will be described with reference to FIG.

In the figure, 32 is a damper assembly,
The damper assembly 32 includes an electric damper 38, a heat insulating material 39 surrounding the damper 38, a case 40, and the like.

The heat insulating material 39 is provided with the protruding wall 2.

And a cool air passage 43 connected to a return duct 45 for guiding the return cool air of the refrigerator compartment 11 to the cooler 8.

Reference numeral 47 denotes an electric component box (for example, housing a substrate 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 circulating fan 20, the cool air blown out to the freezing room 9 has discharge ports 48,
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.

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.
Is returned to the lower part of the cooler 8 through a return duct 45 provided in the protruding wall 44. At this time, vegetable room 10
Is cooled by turning a part or all of the cool air that has cooled the refrigerator compartment 11.

Then, the cool air after cooling the vegetable compartment 10 is returned to the cooler 8 through the vegetable compartment cool air return port 46 provided in the middle of the return duct 45.
