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 freezer compartment 9 is the lowest stage, the center is a vegetable compartment 10 and the refrigerator compartment 11 is above it.

In the refrigerator main body 1, the rear part of the freezer compartment 9 has an upper bottom in comparison with the front part for housing the compressor 6. Along with this, the drawer container 16 of the freezing room 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 vertically.

A cooling air circulation fan 20 is provided above the cooler 8. 21 is a fan motor. The cooler 8 and the cooling air circulation fan 20 are located on the back of the refrigerator body 1 as shown in FIG.

Therefore, in the case where the lower surface of the freezer compartment 9 is at the upper bottom by the compressor 6, the position of the cooling air circulation fan 20 is higher than the upper surface of the freezer compartment 9 (the lower surface of the partition wall 22). It will be located in.

Reference numeral 22 denotes a partition wall as described above. This partition 2
2 thermally partitions 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 cooling 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 form 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. Based on the partition plate 23, the rising portion 22a is rising upward.

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 passes through the fan guard 25 to the freezing room 9 by the operation of the cool air circulation fan 20. What is blown out.

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 the figure, and forms a cool air passage between the lower surface of the partition wall 22 and the cool air duct 27.

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 the foam insulating material 4 is foamed. 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 front surface of the opening 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.

After foaming, the second partition wall 22c forms the box 5
Is to be assembled. 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 and the cooling air circulation fan 20 and the fan motor 21 described above are used. Between the partition wall 22 and the third partition wall 28 (3
It is easy to guess that it is almost impossible to assemble through (within 0 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 second partition wall 22c having the rising portion 22a 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 such that the cooler 8 can be taken in and out when the cooler 8 is assembled into the cooler room 19, and that the work of assembling the cooler 8 and the like can be performed. It is something to keep.

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 drawing.

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

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

Accordingly, the cool air from the cooling chamber 19 through the cooler 8 reaches the damper assembly 32 via the protruding wall 30, and only a necessary amount of the cool air is cooled by the operation of the damper. Is to be supplied.

18 is a drawer container for a vegetable room. As shown in the drawing, the drawer container 18 for the vegetable compartment is cut out so that the protruding wall 29 and the rising portion 22a of the partition wall 22 travel to the vegetable compartment 10 side.

The drawer containers provided in the refrigerator, such as the drawer container 18 for the vegetable compartment, except for the special one (double rail), usually do not pop out from the refrigerator opening surface (the partition plate 23 surface) without the whole. Can only draw 2 / 3rd place. 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 behind the drawer container 18. In the present application, the damper assembly 32 is installed in order to use the invalid space.

Reference numeral 41 denotes a refrigerator compartment duct for supplying cool air from the damper assembly to the refrigerator compartment 11. Cool air is blown out from the duct 41 into the refrigerator compartment 11 as shown in the figure.

Next, the structure and mounting structure of the partition wall 22 will be described with reference to FIGS.

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 22b
Although not shown in the figure, it is mounted in a guide groove formed in the inner box 3 by sliding from the front surface and mounted by a conventionally used method.

Reference numeral 34 denotes a screw tightening guide hole provided at both ends with respect to the second partition wall 22c. Reference numeral 35 denotes a step formed on the side wall of the inner box 3 for attaching a partition wall. Utilizing this step 35, the second partition wall 22c is screwed to the second partition wall 22c.

That is, the back of the second partition wall 22c is
As shown in FIG. 1, it is attached to the protruding wall, both sides are assembled to the step 35, and the front part is assembled to the first partition wall 22b as shown in FIG.

As is apparent from the figure, the second partition wall 22
c is a cooler 8 and a cool air circulation fan 2 to a cooler room 19.
At the time when the installation of the “0” has been completed, it is attached in such a manner that the lid is placed from above. Of course, the second partition wall 22
It is natural that a sealing material for preventing cool air and water leakage is applied to the step portion 35, the protruding wall 29, and the contact portion with the first partition wall 22b. As means for facilitating the attachment of the sealing material, the second partitioning wall 22c is formed in a container shape as shown in FIG. 6, and a flange 37 is provided on an end surface thereof. It is conceivable to paste it.

Needless to say, at this time, the inner box 3, the protruding wall 29, and the first partition wall 22b serving as the receiving surfaces 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 chamber 19 formed below the damper assembly 32 will be described with reference to FIG.

In the figure, 32 is a damper assembly, this damper assembly 32 is an electric damper 38 and this damper 3
8 comprises a heat insulating material 39 wrapping the case 8 and a case 40.

However, the heat insulating material 39 includes the protruding wall 2.
The cool air passage 4 guides the cool air received in the cool air passage 31 provided in the motor 9 to the electric damper 38 and guides the cool air passing through the electric damper 38 to the refrigerator compartment duct 41 as shown by the arrow.
2, and a cool air passage 43 connected to a return duct 45 that guides cool air returning from the refrigerator compartment 11 to the cooler 8.

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, of the cool air forcedly circulated by the cool air circulation fan 20, the cool air blown out to the freezing compartment 9 is discharged to the discharge ports 48 and 49.
The air is blown out to the freezing compartment 9 through the fan guard 25 (FIG. 1) 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 on the duct assembly side through the cool air passage 31 formed in the protruding wall 29, and the amount of cool air controlled by the electric damper 38 is refrigerated. It is blown out from the room duct 41 to the refrigerator compartment 11 as shown in FIG.

Further, the cool air after cooling the refrigerator compartment 11 passes through a 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, and is formed as a second projecting air. It is returned to the lower part of the cooler 8 through a return duct 45 provided in the wall 44. At this time, the vegetable compartment 10 is cooled by turning part or all of the cool air that has cooled the refrigerator compartment 11.

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