The return passage 34 leads downward from the vegetable compartment 5 and is connected to the lower end of the cooler compartment 12 . Moreover, the partition part 18 which forms the bottom wall of the refrigerator compartment 4 is provided with the communication port 4f which communicates with the refrigerator compartment 4 and the vegetable compartment 5. As shown in FIG.

A blower fan 10 , a baffle plate 23 , and a blower fan 24 are arranged in the upper passage 9 from below. Blower fan 10 (first blower fan) is arranged at a position overlapping with partition 36 in frontal projection. The lower passage 29 branches off from the upper passage 9 on the discharge side of the blower fan 10 and extends downward. Damper 23 is opened when cooling refrigerator compartment 4 and vegetable compartment 5 , and cold air is guided to refrigerating passage 8 of upper passage 9 formed above damper 23 . The blower fan 24 is driven when the damper 23 is opened.

The refrigerating passage 8 above the baffle plate 23 of the upper passage 9 is arranged along the back surface and the ceiling surface of the refrigerating chamber 4 , and a plurality of discharge ports 8 a to 8 f are opened facing the refrigerating chamber 4 .

The discharge port 29d is arranged vertically below the vegetable compartment 5 .

FIG. 5 shows a perspective view of the lower portion of the upper passage 9 of the cold air passage 7 and the cooler chamber 12 . FIG. 6 shows a schematic perspective view of the vegetable compartment 5 . The right side wall 9d of the upper passage 9 and the upper wall 12b of the cooler chamber 12 are connected by an inclined surface 12a. In this way, cold air smoothly flows from the cooler chamber 12 having a large lateral width into the upper passage 9 having a narrow lateral width disposed behind the freezing section 21 (see FIG. 1 ). Therefore, the pressure loss in the cool air passage 7 can be reduced.

At this time, between the rear portion of partition 19 forming the bottom wall of vegetable compartment 5 and the rear portion of partition 20 forming the left side wall, avoiding portion 5d for avoiding interference with inclined surface 12a is provided. The avoiding part 5d is integrally formed with the partition part 19 and the partition part 20, and the heat insulating material 13 is filled in the avoiding part 5d. In addition, a chamfer (not shown) for avoiding interference with the avoiding portion 5d is formed between the side wall and the bottom wall of the storage cabinet 50 (see FIG. 4 ) in the vegetable compartment 5 .

In refrigerator 1 configured as described above, compressor 31 and blower fan 10 are driven to exchange heat between air flowing in cooler chamber 12 and cooler 11 to generate cool air. The generated cold air is ejected from the ejection port 9a to the ice making compartment 25, and is ejected from the ejection port 9b to the freezing compartment 26. In addition, cold air flows through the lower passage 29 and is ejected from the ejection ports 29a, 29b, and 29c into the freezer compartment 6 . The ejected cold air flows through the ice making compartment 25, the freezing compartment 26, and the freezing compartment 6, and returns to the cooler 11 through the return port 9c. In this way, cooling of the ice making compartment 25, the freezing compartment 26, and the freezing compartment 6 is performed.

When the baffle plate 23 is opened, cold air flows into the refrigerating passage 8 of the upper passage 9, and is ejected into the refrigerating compartment 4 from the discharge ports 8a, 8b, 8c, 8d, 8e, and 8f. The blown cold air flows toward the front of the refrigerator compartment 4, flows downward, and flows out through the communicating port 4f. In this way, cooling in the refrigerator compartment 4 is performed.

Then, the cold air is ejected into the vegetable compartment 5 through the communicating port 4 f , flows from the front to the rear of the vegetable compartment 5 , and returns to the cooler compartment 12 through the return passage 34 . In this way, cooling in the vegetable compartment 5 is performed.

According to this embodiment, the cool air passage 7 has the cooler chamber 12 in which the cooler 11 is provided, and the upper passage 9 extending upward from the cooler chamber 12 . In addition, the cooler compartment 12 is provided from below the freezing compartment 21 to below the vegetable compartment 5 , and the upper passage 9 is provided behind the freezing compartment 21 avoiding the rear of the vegetable compartment 5 . Therefore, cold air generated in cooler 11 is supplied to refrigerator compartment 4 , freezer section 21 , and freezer compartment 6 via upper passage 9 disposed behind vegetable compartment 5 . Therefore, the temperature rise of the cool air flowing through the upper passage 9 is suppressed, and the cooling capacity of the refrigerator 1 can be improved.

Also, the lower passage 29 of the cold air passage 7 branches off from the upper passage 9 downstream of the blower fan 10 (first blower) and extends downward. Therefore, the length of the lower passage 29 that branches off from the upper passage 9 and blows cool air from the blower fan 10 can be shortened. Therefore, the pressure loss in the cool air passage 7 can be reduced.

Moreover, since the side wall 9d of the upper passage 9 and the upper wall 12b of the cooler chamber 12 are connected by the inclined surface 12a, cold air flows into the upper passage 9 from the cooler chamber 12 easily.

In addition, since the freezing section 21 is divided up and down, and the ice making chamber 25 is disposed above and adjacent to the refrigerator compartment 4, ice can be easily made in the ice making chamber 25 using the water in the water storage box 72 in the refrigerator chamber 4.

<Second Embodiment>

Next, FIG. 7 has shown the front view of the main-body part 2 of the refrigerator 1 of 2nd Embodiment. For convenience of explanation, the same reference numerals are assigned to the same parts as those in the first embodiment shown in FIGS. 1 to 6 described above. This embodiment differs from the first embodiment in the shape of the upper passage 9 . Other parts are the same as the first embodiment.

The upper passage 9 is provided with division passages 32 a , 32 b divided left and right by a partition wall 32 c extending vertically between the blower fan 10 and the damper 23 . The discharge ports 9a, 9b are opened in the left divided passage 32b, and the blower fan 10 and the damper 23 are connected through the right divided passage 32a.

In this way, when the damper 23 is opened, cold air can be smoothly guided to the refrigerating passage 8 above the damper 23 . In addition, it is possible to prevent the cold air guided to the passage 8 for refrigeration from decreasing due to the discharge of cold air from the discharge ports 9 a and 9 b. Therefore, it is possible to reduce supercooling of freezer compartments 6 and 26 and ice maker compartment 25 when cooling refrigerator compartment 4 and vegetable compartment 5 .

In addition, in the case where the divided passages 32a, 32b are not provided in the upper passage 9, if the air volume of the upper passage 9 from the blower fan 10 to the ejection port 9a of the ice making chamber 25 is reduced due to the clogging of the cooler 11, when the damper is opened, When the plate 23 is driven and the blower fan 24 is driven, the backflow of cold air drawn from the discharge port 9a occurs. However, since the cold air sent from the blower fan 10 is immediately branched by the divided passage 32a and the divided passage 32b, the backflow from the outlet 9a is reliably prevented, and the cooling efficiency of the refrigerator 1 can be improved.

According to this embodiment, the same effect as that of the first embodiment can be obtained. In addition, since the upper passage 9 has the divided passages 32a, 32b, cold air can be smoothly guided to the passage 8 for refrigeration, and supercooling of the freezer compartments 6, 26 and the ice making compartment 25 can be reduced.

In addition, in this embodiment, the upper passage 9 may be divided in the front-rear direction by the partition wall 32c, and the divided passage 32a may be arranged behind the divided passage 32b.

<Third Embodiment>

Next, FIG. 8 shows a front view of the main body 2 of the refrigerator 1 according to the third embodiment, and FIG. 9 shows a C-C sectional view of FIG. 8 . For convenience of explanation, the same reference numerals are assigned to the same parts as those in the first embodiment shown in FIGS. 1 to 6 described above. The present embodiment differs from the first embodiment in that a blower fan (second blower) 33 is provided. Other parts are the same as the first embodiment.

The blower fan 33 is provided behind the discharge port 29d. Cool air is blown into the freezer compartment 6 by driving the cooler 11 , the blower fan 10 , and the blower fan 33 . At this time, even if the discharge port 29d is separated from the blower fan 10, the cold air can be reliably blown out from the discharge port 29d into the freezer compartment 6 by the blower fan 33 . In this way, the cold air is scattered and sprayed from the discharge ports 29a to 29d, so that the temperature in the freezer compartment 6 can be made uniform. In addition, a plurality of discharge ports 29d may be provided in the right end portion of the freezer compartment 6 .

According to this embodiment, the same effect as that of the first embodiment can be obtained. Moreover, the temperature in freezing compartment 6 can be made uniform by providing blower fan 33 . In addition, the blower fan 33 may be provided in the second embodiment.
