On the other hand, the upper partition wall 8 is composed of an upper plate 66 and a lower plate 67 made of a hard resin and a molded heat insulating material 68 provided along the lower surface of the upper plate 66 as shown in FIGS. The ice greenhouse duct 48 is formed between the formed heat insulating material 68 and the lower plate 67. Ice greenhouse duct 4
Numeral 8 is configured to expand forward from a rear entrance 48A by a blind alley-shaped partition wall 69 provided on the upper surface of the lower plate 67, and the lower plate 67 located in the middle and front thereof has an ice greenhouse. A plurality of discharge ports 71 are formed.

A lower plate 67 on the front and right side of the partition wall 69 is also provided.
Are provided, and two refrigerating chamber suction ducts 77 and 78 are arranged side by side in the upper partition wall 8 outside the ice greenhouse duct 48. The front of the upper plate 66 has left and right refrigerator compartment suction ports 79 and 81 formed on the left and right, and the left refrigerator compartment front suction port 7.
Numeral 9 communicates with the inlet 77A of the left refrigerator compartment suction duct 77, and the right refrigerator compartment front suction port 81 communicates with the inlet 78A of the right refrigerator compartment suction duct 78. Also,
The rear end of each refrigerator compartment suction duct 77, 78 communicates with the return duct 63.

In this case, the passage cross-sectional area of the left refrigerator compartment suction duct 77 is formed to be larger than the passage cross-sectional area of the right refrigerator compartment suction duct 78, and the suction portion 77A is also connected to the suction portion 7.
8A (FIG. 15). Here, since the refrigerator compartment suction ducts 77 and 78 are formed so as to detour from the front side of the ice greenhouse duct 48 to the right side, the passage length of the refrigerator compartment suction duct 77 on the left side is equal to the passage length of the refrigerator compartment suction duct 78 on the right side. It is longer than long.

A narrow communication passage 83 is formed between the partition wall 72 and the partition wall 69. The communication passage 83 connects the front end of the ice greenhouse duct 48 and the suction portion 77A of the refrigerator compartment suction duct 77. ing. An ice greenhouse suction port 84 is formed on the right side of the back plate 62 of the ice greenhouse 10 and communicates with the return duct 63.

On the other hand, the upper end of the vegetable compartment duct member 86 is connected to the right portion of the molded heat insulating material 38, and the right side of the cooling room 24 is lowered downward, forming a vegetable compartment duct 87 inside. . The upper end of the vegetable compartment duct 87 communicates with the return duct 63, and the lower end is opened at a vegetable compartment discharge port 88 at the upper right rear of the vegetable compartment 12.

A vegetable compartment suction duct 91 is formed in the lower partition wall 9. The vegetable compartment suction duct 91 is connected to the vegetable compartment 1.
2, opened at the vegetable compartment suction port 92 opened at the top of the back,
In addition, it communicates with the lower end of the cooling chamber 24.

As shown in FIG. 16, the pre-partitioning member 15 is attached to a main body 93 made of hard resin, a molded heat insulating material 94 provided in the main body 93, a front plate 96 made of steel plate, and a back surface thereof. The lower wall of the main body 93 has a lower front portion 93A and a lower portion 93B.
Has a stepped shape.

At the rear end of the front portion 93A, an engagement portion 93C is formed integrally with the rear end of the front portion 93A so as to protrude rearward with a space below the rear portion 93B. . The base portion 98A of the seal member 98 is attached to the engaging portion 93C by engaging from behind, and the soft fin piece 98B projects forward and downward.

The soft fin piece 98B of the seal member 98 is to be tightly sealed to the rear surface of the front edge of the container 17A with the heat insulating door 17 closed, and in this case, the base 98A of the seal member 98 is closed. The lower surface is substantially flush with the lower surface of the front portion 93A of the main body 93. That is, since the base portion 98A of the seal member 98 or its mounting portion (formed on the pre-partitioning member 15) does not protrude downward, the container 17A does not get caught, and the vertical dimension of the container 17A is enlarged accordingly. Thus, the effective volume can be expanded.

This structure is similarly formed on the other partition walls 7, 8, and 9. Also, 104
Is a refrigerator compartment temperature sensor for detecting the temperature in the refrigerator compartment 11, attached to the rear duct plate 49, and 106 is an ice temperature compartment temperature sensor for detecting the temperature in the ice compartment 10;
It is attached to the lower plate 67.

Further, a machine room 99 is formed at a lower portion of the heat insulating box 6, and a compressor 101 and a condenser (not shown) forming a well-known refrigeration cycle are provided at a rear portion inside the machine room 99. , A machine room blower and the like are installed.
A kick plate 102 is attached to the lower side of the heat insulating door 18 at the front end of the machine room 99. The kick plate 102 has an air inlet 103 for ventilating the inside of the machine room 99. ing.

With the above configuration, the compressor 101 and the blower 2
9 is operated, the cooling chamber 2 cooled by the cooler 26 is operated.
4 is sucked upward by the fan 32 of the blower 29, and is discharged from the freezing chamber discharge port 13A in the front.
3 is blown out. Then, the container 16 in the freezing room 13
A, after circulating and cooling in the 17A, the cool air flows from the lower freezer inlets 13B, 13B, 13C, 13C to the cooling chamber 2A.
Return to 4 As a result, the freezing compartment 13 is maintained at a predetermined freezing temperature (about −20 ° C.). The compressor 101
The operation of the blower 29 is controlled based on a freezing room temperature sensor that detects the temperature in the freezing room 13.

Here, the cold air flowing from the freezer compartment suction ports 13B, 13B flows into the cooler 26 from the lower region 26A of the cooler 26 and rises between the fins 27. The cool air flowing in from the ports 13C, 13C is in a region 26 slightly lower than the central portion above and below the cooler 26.
B flows into the cooler 26.

As will be described later, since the humid cold air circulating in the refrigerator compartment 11, the ice warming compartment 10 and the vegetable compartment 12 flows from the vegetable compartment suction duct 91 from the area 26A at the lower end of the cooler 26, the cooling is performed. A large amount of frost adheres and grows in the region 26A of the cooler 26, but the cool air flowing from the freezing chamber suction ports 13C, 13C flows from above (downstream side) into the region 26B having a low fin density of the cooler 26, and thereafter Since the fin density is introduced into the region below the dense blower 29, the flow of the cool air flowing from the region 26B is not hindered by the frost that has grown in the region 26A.

The left and right front and rear edges of the cooler 26 (the outer portions of the cooler 26 where the edges of the vertically extending fins 27 through which the cool air flows) are located.
.. Are configured, even if the area 26A is blocked by the growth of frost, the area 26C
Frost blockage is delayed by the presence of

Therefore, even in such a case, since the cool air can be introduced into the cooler 26 from the region 26C and heat exchange can be performed, the heat exchange between the fins 27 and the flowing cool air is generally maintained, and the cooler 26 is cooled. Can significantly improve the cooling capacity.

Further, since the regions 26C are formed on the left and right other than the center of the cooler 26 corresponding to the blower 29, the fin density of the portion of the cooler 26 where cool air flows most becomes dense as described above. Therefore, when the frost grows while maintaining the heat exchange efficiency in a state where there is no or little frost, the flow of the cool air is maintained from the regions 26B and 26C as described above, and the heat exchange is secured. Will be able to do it.

A part of the cool air blown out from the blower 29 flows into the guide duct 39 and is divided in two directions by the branch duct 42, and one of the cool air passes through the cooler baffle 43 of the motor damper 46, and the other cools the rear duct. It flows into 47. Cold air flowing into the refrigerator compartment rear duct 47 is discharged from the refrigerator compartment outlet 11A.
.. Are blown out into the refrigerator compartment 11 and circulated through the inside of the refrigerator to cool it.
9 and 81.

The other branch of the branch duct 42 flows into the ice greenhouse duct 48 via the ice greenhouse baffle 44 of the motor damper 46. The cold air that has flowed into the ice greenhouse duct 48 is blown out from the ice greenhouse discharge ports 71 to the ice greenhouse 10, circulates through the inside and cools, and then flows into the ice greenhouse suction port 84.

The motor damper 46 opens and closes the baffle 43 based on the output of the refrigerator compartment temperature sensor 104, and maintains the refrigerator compartment 11 at a refrigerator temperature of about + 5 ° C. Also, the baffle 44 based on the output of the ice greenhouse temperature sensor 106 is used.
To open and close the container 19A in the ice greenhouse 10,
Maintain an ice temperature range of about -3 ° C.

The above-mentioned refrigerator compartment suction port 61 and ice greenhouse suction port 8
The cool air that has flowed into 4 flows into return duct 63 as it is, but the cool air that has flowed through inlets 79 and 81 in front of the refrigerator compartment flows into return duct 63 through refrigerator duct intake ducts 77 and 78, respectively. Further, a part (a small amount) of the cold air flowing into the ice greenhouse duct 48 passes through the communication passage 83 directly without passing through the ice greenhouse 10, and the refrigerator air suction duct 77.
And merges with the cool air from the suction port 79 and flows into the return duct 63.

Here, as described above, the passage length of the refrigerator compartment suction duct 77 on the left side is longer than the passage length of the refrigerator compartment suction duct 78 on the right side. Therefore, at the same passage cross-sectional area and suction area, the flow path resistance of the refrigerator compartment suction duct 77 becomes larger than the flow path resistance of the refrigerator compartment suction duct 78, so that the amount of cold air sucked from the refrigerator compartment front suction port 79 is refrigerated. This is smaller than the amount of cold air sucked from the front suction port 81.

If the amount of the intake cold air differs between the left and right sides of the refrigerator compartment 11, the cooling effect of the front part inside the refrigerator compartment 11 will be deviated left and right, and in the embodiment, the left side will not cool down more than the right side. However, as described above, the passage cross-sectional area of the left refrigerator compartment suction duct 77 is formed larger than the passage cross-sectional area of the right refrigerator compartment suction duct 78, and the suction portion 77A is formed to be larger than the suction portion 78A. The flow path resistance of the two ducts 77 and 78 is made substantially uniform. Therefore, the amount of cool air flowing into the inlets 79 and 81 in front of the refrigerating compartment is substantially uniform, and the refrigerating compartment 11
The inside can be cooled uniformly.

Next, the cool air that has flowed into the return duct 63 flows into the vegetable room duct 87, descends there, and is discharged from the vegetable room discharge port 88 into the vegetable room 12. Then, after circulating in the vegetable compartment 12 and indirectly cooling the inside of the container 18A, it is sucked from the vegetable compartment 92, passes through the vegetable compartment suction duct 91 formed in the lower partition wall 9, and reaches the uppermost portion of the cooling chamber 24. Return to the bottom. Then, as described above, the region 26 of the cooler 26
A flows again into A.

As a result, the vegetables in the container 18A are kept cool at a temperature of + 3 ° C. to + 5 ° C. in a state where drying is prevented.
3, that is, low-temperature cold air (as it is cooled by the cooler 26) that has not passed through the ice room 10 or the refrigerator room 11. Even when the load in the inside increases and the cold air temperature rises, the cooling capacity in the vegetable compartment 12 is ensured.
