A cool air outlet 24 is formed on the right inclined surface 23a of the 23 and obliquely rearward to the right. When the fan 20a rotates, the cool air in the cooler chamber 17 is sucked by the fan 20a and sent out to the cool air supply passage 21, and a part of the cool air sent out into the cool air supply passage 21 is made into ice from each of the outlets 22. The cold air is blown out into the chamber 6 and the freezing room 8 and the remaining cool air is blown out from the cool air outlet 24.

The cool air outlet 24 is connected to a damper device 25 provided on the rear side of the specification switching chamber 7. As shown in FIGS. 3 and 4, the damper device 25 surrounds the mounting plate 26 as a front plate, a damper main portion 27 disposed on the rear side of the mounting plate 26, and the damper main portion 27. And a box-shaped cover 28 that is open to the front and is attached to the specification switching room 7. The mounting plate 26 also functions as a back plate of the specification switching room 7, and blocks the rear opening of the specification switching room 7 to partition between the specification switching room 7 and the damper main portion 27.

Here, inside the cover 28, a plurality of bosses 28a (only one is shown in FIG. 4) projecting forward from the rear surface are integrally provided, and the bosses 28a are integrally formed.
The mounting plate 26 is adapted to be screwed. The damper main part 27 and the mounting plate 26 are formed in the same size as the rear opening so as to be able to pass through the rear opening of the specification switching chamber 7, whereby the mounting plate 26 and the damper main part are formed. 27 is configured to be removable from the inside of the specification switching chamber 7 to perform repair or the like.

The cool air discharged from the chilled chamber 16
It is blown into the inside and the refrigerator compartment 5.

The cool air supplied to the ice making room 6, the freezing room 8, and the specification switching room 7 cools the respective rooms, and then cools the cooling room 1
The cold air supplied to the refrigerator compartment 5 and the chilled compartment 16 is then supplied to the vegetable compartment 9 to cool the vegetable compartment 9 and finally returned to the cooler compartment 17. Then, the air returned to the cooler chamber 17 is cooled again by the cooler 17 and circulates so as to be supplied to the chambers 5 to 9 and 16.

The refrigerating room 5, the chilled room 16, and the specification switching room 7 are cooled by the cool air blown out from the first and second outlets 32 and 33. Then, by controlling the supply amount of the cool air, the cool room 5 (the chill room 1) is controlled.
6) and the cooling temperature of the specification switching chamber 7 is controlled. In order to control the amount of cold air blown out from the first and second outlets 32 and 33, a branch path 3 is

When the temperature sensor for the specification switching room detects the ON set temperature, the baffle 36 is opened to supply cool air into the specification switching room 7 and when the OFF set temperature is detected,
The baffle 36 is closed, and the supply of cold air into the specification switching chamber 7 is stopped. Thereby, the temperature of the specification switching chamber 7 is controlled. In this case, the on-set temperature and the off-set temperature of the specification switching room temperature sensor can be switched by a setting device (not shown), and the specification of the specification switching room 7 is changed by the switching of the setting temperature. , A chilled room, a partial room, a refrigerator room, a vegetable room and the like can be switched to a plurality of specifications.

Incidentally, when the use switching room 7 is used as a vegetable room, it is preferable that the room is kept at an appropriate humidity for storing vegetables. In this regard, the internal volume of the use switching room 7 is relatively small, and if a small amount of cool air is supplied, the temperature reaches the off set temperature in the vegetable room specification and the supply of the cool air is stopped immediately. There is little air exchange, so the moisturizing effect is high and it is suitable for storing vegetables.

Similarly, in the refrigerating room 5, when the temperature sensor for the refrigerating room detects the on-set temperature, the baffle 37 is opened to supply cool air into the refrigerating room 5, and when the off-set temperature is detected, the baffle 37 is turned on. Is closed, and the supply of cold air into the refrigerator compartment 5 is stopped. Thereby, the temperature of the refrigerator compartment 5 is controlled.

As described above, the moisture contained in the air adheres to the cooler 17 which cools the air circulating in the refrigerator body 1 as frost, so that the frost is forcibly melted and removed. Is provided below the cooler 18. The water generated by the defrosting is received by a gutter-shaped cover member 41 as a water receiving member,

The right side surface of the rear portion) is formed on a slope 3a, and an opening 44 for communicating the cool air outlet 24 and the cool air inlet 30 is formed in the slope 3a.

FIG. 3 shows the inner box 3 formed by vacuum forming, and the ice making room 6 and the freezing room 8 are communicated with each other. And
A rectangular insertion opening 46 is formed in the front part of the part 45 for storing the box 43 by post-processing, and the rear parts of the ice making chamber 6 and the freezing chamber 8 are cut off, and the cover member 41 is attached to the cut-out part. Keep it. Also, box 43
Is attached to the partition frame 47 in advance. The partition frame 47 is mounted inside the inner box 3 at the front of a partition wall that partitions the chambers 5 to 8 from each other. This partition frame 47
Thereby, the space between the ice making room 6 and the freezing room 8 is partitioned.

Here, a procedure for manufacturing the refrigerator body 1 by inserting the inner box 3 into the outer box 22 will be described. First, the box 43 is attached to the rear side of the partition frame 47.
Is inserted into the storage part 45 through the insertion opening 46, and the partition frame 47 is fixed to the front of the partition part that partitions the refrigerator compartment 5, the ice making compartment 6, the specification switching compartment 7, and the freezing compartment 8 from each other.

Further, the damper main portion 27 is accommodated in the cover 28 of the damper device 25, and the mounting plate 26 is then mounted on the boss portion 2.
8a. Then, the cover 28 is fixed to the periphery of the back surface of the box 43 inserted and arranged in the storage part 45 by screwing as described above, and the distal end portion of the cool air introduction passage 29 is screwed as shown in FIG. It is fixed to the inner box 3. At this time, a packing 49 is applied between the periphery of the cool air inlet 30 at the end face of the cool air introduction passage 29 and the periphery of the opening 44 of the inner box 3, and the sealing between the two is performed by the packing 49. . As described above, the damper device 25 is attached to the outside of the back of the box 43 so as to cover the open rear surface.

On the other hand, a cooler 17 is arranged at the rear portion inside the freezing compartment 8 of the inner box 3. At this time, the reinforcing plate 50 is previously addressed to the inside of the back surface of the ice making chamber 6. Then, the inner box 3 to which the box 43, the damper device 25, the cooler 17 and the like are attached is housed in the outer box 2, and the foam heat insulating material 4 is filled between the outer box 2 and the inner box 3, and 1 is manufactured. When filling the foam insulating material 4, the back surface of the box 43 is closed by the cover 28, so that the foam insulating material 4 does not enter the box 43.

Thereafter, the partition member 19 to which the fan device 20 is mounted is inserted into the ice making room 6 and the freezing room 8 from the front opening thereof, and is arranged so as to cover the cooler 17 from the front side. At this time, the lower part of the partition member 19 is inserted into the cover member 41 as shown in FIG. 2, and the engaging portion 19c formed on the front partition plate 19a is engaged with the front upper end of the cover member 41, The upper end and the left and right sides of the front partition plate 19b are fixed to the refrigerator main body 1 with a plurality of screws 51 (only one is shown).

At this time, as shown in FIG.
A packing 52 is applied between the periphery of the cool air outlet 24 of FIG. 9 and the periphery of the opening 50a of the reinforcing plate 50 which is continuous with the opening 44 of the inner box 3, so that the packing 52 seals between the two. I do. Then, the partition member 19 is pressed rearward by the tightening of the screw 51, and the pressing force causes the periphery of the cool air outlet 24 to be pressed to the cool air inlet 30 via the periphery of the opening 44 of the inner box 3. Thereby, the space between the cool air outlet 24 and the cool air inlet 30 is more reliably sealed.

9, the cold air outlet 24 of the partition member 19 addressed from the front side is formed so that the cold air outlet 24 is formed obliquely to the right and left and the cold air inlet 30 of the damper device 25 is formed obliquely forward and to the left.
Comes into contact with the cold air inlet 30 side of the damper device 25 with a pressing force, so that the both can be sealed more reliably, and it is possible to prevent the cool air from leaking out between the two ports 24 and 30.

During the operation of the compressor 39, the air flowing into the cooler room 45 from the lower portion thereof flows into the fan 2
Since 0a is rotating in the direction of arrow B shown in FIG. 5, as shown by arrow C in FIG. 5, the air flows in an arc that expands to the right and is drawn into the fan 20a. At this time, since the fan device 20 is arranged on the left side, even if the air flows so as to draw an arc expanding to the right side as described above, the air tends to flow uniformly to the cooler 17 as a whole. Become. Therefore, the cooling capacity of the cooler 17 can be effectively used for air cooling, and the cooler 17 can be made smaller than before.

As described above, since the fan device 20 is provided so as to be deflected to the left side, an extra space is generated above the cooler room 18. In this embodiment, the damper device 25 is provided outside the back of the box 43 (specification switching chamber 7).
Unlike the configuration in which the damper device 25 is inserted and arranged at the rear of the box 43, the box 43 (specification switching chamber 7) is formed next to the ice making chamber 6, and the frontage cannot be made so large. However, the damper device 2 is installed in the extra space at the rear of the specification switching room 7.
5 can be provided.

As described above, since the surplus space generated at the back of the specification switching room 7 can be effectively used as the space for disposing the damper device 25, it is not necessary to provide the damper device unit 55 at the back of the refrigerator compartment 26. . For this reason, unlike the conventional configuration in which the damper device 25 is provided at the back of the refrigerator compartment 5, there is no problem that the lower part of the refrigerator room 5 where the chilled room 12 is provided projects into the refrigerator compartment 5,
The back of the chilled room 16 can be flush with the back of the refrigerator compartment 5.

The present invention is not limited to the embodiment described above and shown in the drawings, but can be extended or modified as follows. The specification switching room 7 may be replaced with, for example, a partial room having a fixed set temperature. In this case,
The damper device 25 only has to function so as to control the supply of cold air to only the refrigerator compartment 5. The fan 20a may be rotated in the right direction (the direction indicated by the arrow B).
And the specification switching room 7 may be reversed, and the damper device 25 may be disposed behind the left specification switching room 7.

According to another aspect of the present invention, there is provided a refrigerator having a structure in which a partition member is arranged at the back of a freezing room to form a cooler room.
It can be widely applied to a refrigerator configured to supply cold air blown from a cold air outlet provided in a partition member to a predetermined storage room via a damper device, and can be variously modified and implemented without departing from the gist thereof. You can do it.

[0041]

As described above, according to the present invention, the cold air inlet of the damper device opens obliquely forward and the cold air outlet of the partition member opens obliquely rearward. Can be pressed against the cold air inlet of the damper device, and the sealing between them can be performed more reliably.
