[0002]

2. Description of the Related Art In a conventional refrigerator-freezer, a refrigerating zone including a refrigerating compartment and a refrigerating zone including a refrigerating compartment are cooled by a single cooler. Therefore, both cooling zones are provided so as to communicate with each other so that cool air circulates between them. In detail, the cool air cooled by the cooler is blown into the refrigerating compartment from a duct provided at the rear of the refrigerating compartment for circulation, and is also blown into the freezing compartment for circulation. The entire interior is cooled by one cooler.

In a freezer-refrigerator that cools the refrigerating room and the freezing room with one such cooler, the evaporation temperature of the cooler is about -2.
The temperature is as low as 7 ° C. Therefore, cold air near -20 ° C flows into the duct for blowing cold air into the refrigerating chamber, and the cold air blown out from the duct is as low as -17 ° C. in this way,
When cold air near −20 ° C. flows in the duct, the wall of the duct on the refrigerating compartment side is also cooled to −20 ° C. Due to the temperature difference between the refrigerating compartment temperature (about 3 ° C.) and the humidity increase in the refrigerator. Condensation occurs on the surface. In addition, dew condensation is likely to occur even when a load is applied by opening and closing the refrigerating compartment door or throwing in something hot.

Therefore, in the conventional refrigerator-freezer, in order to prevent such dew condensation, a heat insulating material such as styrofoam is arranged on the back surface of the duct forming member made of a thin plate-shaped resin molding, and the duct forming member and the heat insulating material are arranged. And form the wall of the duct on the refrigerating room side.

12 and 13 show the structure of the rear duct of the refrigerating compartment in such a conventional refrigerator-freezer.

The inner box 101 forming the heat insulating box of the refrigerator is provided with a recess 104 for forming the rear duct 103 of the refrigerating chamber 102, and the recess 104 is formed with a duct made of a thin resin molding. Material (duct cover) 1
05 is covered. The duct forming member 105 has a plurality of outlets 106 for blowing cold air into the refrigerating chamber 102.
Is provided. A heat insulating material 107 made of expanded polystyrene is arranged on the rear surface of the duct forming member 105. The heat insulating material 107 includes a blowout port 106 of the duct forming member 105.
A cold air outlet 108 is provided corresponding to the above. A temperature sensor 109 for detecting the temperature inside the refrigerating chamber 102 is attached to the front surface of the heat insulating material 107, and a lead wire 110 is provided as an electric wiring for the temperature sensor 109 and the like.

As shown in FIG. 13 , the wall of the duct 103 on the refrigerating chamber 102 side is formed by a duct forming member 105 and a heat insulating material 107 that insulates heat from the duct forming member 105. Therefore, -20 in the duct 103
Even if cold air of ℃ flows in, the surface temperature of the duct forming member 105 can be maintained at a positive temperature by the heat insulating material 107, and the occurrence of dew condensation can be prevented.

[0008]

However, the above-mentioned conventional duct structure has a problem that the heat insulating material 107 acts as a resistance to narrow the cold air passage. Further, in order to form the duct 103, the duct forming member 105 and the heat insulating material 107.
However, there is a problem that manufacturing cost and transportation cost are required.

The present invention has been made in view of such problems, and an object thereof is to eliminate the heat insulating material for forming the duct to eliminate the flow resistance of the cool air and to reduce the cost. To do.

In the refrigerator 10 of the present embodiment as described above, the refrigerant supplied from one compressor 46 is cooled by a switching means such as a valve to cool the refrigerator 20 and cool the refrigerator 28.
By alternately supplying and to each cooling zone 24,
32 is cooled to a predetermined temperature zone (hereinafter, refrigerating cooler 2
The operation mode in which 0 is operated is set to R cooling and refrigerating cooler 28.
The operation mode to operate is called F cooling). And F
By operating the fan 22 during cooling,
Frost attached to the refrigerator 20 for refrigeration evaporates and is returned to the inside of the refrigerating compartment 12 and the vegetable compartment 14, whereby the compartments 12 and 14 are maintained at high humidity (hereinafter, this operation mode is called moisturizing operation). .

As shown in FIG. 6, during the F cooling, the humidity in the refrigerating compartment 12 rises due to the moisturizing operation in the refrigerating zone 24 (up to about 75%). Also increases both the air temperature (a) near the duct forming member 56 and the front surface temperature (a) of the duct forming member 56 (maximum 4 to 5 ° C.), and the front surface temperature (a).
Does not fall below the dew point temperature (0.0 to 0.9 ° C). Therefore, dew condensation does not occur on the front surface of the duct forming member 56.

The seal member 78 is pressed against the inner box 50 and the duct forming member 56 to compress the seal member 78, so that the inside of the storage portion 72 is shielded from the cool air in the first duct 34.

In the example shown in FIG. 10, a sealing rib 80 that is superposed on the inner peripheral surface of the enclosure 76 provided in the inner box 50 is
The rib 80 overlaps with the inner peripheral surface of the enclosure 76 by standing upright from the rear surface of the peripheral edge of the opening 74 of the duct forming member 56 and covering the inner box 50 with the duct forming member 56. It is configured to be shielded from the cold air in the first duct 34.

In the example shown in FIG. 11, the accommodating portion 72 is formed by recessing the duct forming member 56 rearward so that the recessed portion 8 is formed.
It is formed inside 2. A lead wire insertion hole 84 for drawing the terminal 70a of the lead wire 64a from the inner box 50 and the terminal 70b of the lead wire 64b to the temperature sensor 62 into the housing portion 72 is provided on the rear surface of the recessed portion 82. ing. The lead wire insertion hole 84 is sealed by bringing the rear surface of the recessed portion 82 into contact with the inner box 50, so that the inside of the storage portion 72 is shielded from the cool air in the first duct 34. There is. In this case, the front opening surface of the depressed portion 82 serves as the opening 74 for connecting work.

According to the examples of FIGS. 9 to 11, since the connecting portion 70 of the lead wire 64 is shielded from the cool air in the first duct 34, the metal of the connecting portion 70 can be prevented from rusting. 9 to 11, both terminals 70a and 70b of the lead wires 64a and 64b are pulled out from the opening 74 to the front side and connected, and the connection section 70 is connected to the storage section 7.
After being stored in 2, the opening 74 is closed by the cover 73.
