By the engagement of the engaging hole 16d and the engaging claw 17e, the members disposed inside can be stably held at a specific position without being loosened (sounding sound).

Further, the strength of the rotary separator 13 can be increased without increasing the number of parts, and the bending deformation of the suction surface 16a in the longitudinal direction can be prevented, and the front and rear positions of the doors 7 and 8 can be suppressed from being deviated, which is good. Keep the exterior design of the refrigerator.

As can be seen from Fig. 7, the above cross section is substantially The front end portion of the side wall portion 17b of the partitioning frame body 17 is formed with a slightly recessed groove 17f in the longitudinal direction at the corner portion on the inner surface side thereof, as described above, when the rotary partition body 13 is assembled, so that Both of the end edges of the folded-back portions 16c of the partition plate 16 are fitted in a state in which the concave grooves 17f are completely aligned with each other.

By this fitting, it is possible to suppress a gap between the partition portion of the partition plate 16 and the partition frame 17, and it is possible to ensure a beautiful appearance of the interface of the front corner portion.

Further, a pivot portion 15 facing the door inner panel 14 side is provided on one side of the rotary partition body 13, and a plurality of longitudinally parallel side wall portions 17b of the partition frame body 17 are vertically arranged in parallel in the longitudinal direction. In the present embodiment, the strip has two ribs 25 (see FIG. 6) protruding toward the door inner panel 14 when the door is closed.

When the rotary partition 13 is rotated at the time of closing the door, and the door pads 11, 12 of the left and right doors 7, 8 are attracted to the surface of the partition 16 (refer to FIG. 3), the gap between the rib 25 and the inner panel 14 is also reduced. It can suppress the flow of cold air from the inside of the refrigerator toward the door mat 11 to reduce heat leakage.

Further, the anti-pivot side of the rotary partition 13 is narrowed by the projection formed on the door inner panel 14 opposite to the rotary partition 13 when the door is closed.

By the slit 26, heat transfer from the inside of the refrigerator to the outside of the refrigerator to the side wall surface 17b as the heat conductor can be suppressed, and the air flow can be suppressed by the rib 25 to form a heat blocking portion.

With such a configuration, heat leakage from the inside of the refrigerator to the outside of the refrigerator can be suppressed, whereby the cooling can be effectively performed, and the power consumption can be reduced.

Since the rib 25 is provided on the side wall surface 17b of the pivotal side, and the slit 26 is provided between the two ribs 25, it is not exposed to the outside, so that the appearance is not impaired.

Further, as shown in another embodiment in FIG. 9 which is a cross-sectional view of the same portion as that of FIG. 5, if the central portion of the surface of the spacer 16' which forms the door pad adsorption portion is formed, the reinforcement in the longitudinal direction is formed. The edge 27 can increase the strength of the stress in the longitudinal direction of the spacer 16' itself, so that the strength of the rotary separator 13' in the up and down direction can be further enhanced, and as a result, the left and right doors 7, 8 can be further suppressed from being in the front and rear stages. The difference happened.

Further, although the reinforcing edge 27 has been described as having a concave shape, it may be formed as a ridge without affecting the suction portion of the door mat.

Further, in the present embodiment, before the pivot portion 15 is disengaged from the shaft hole 30, the convex portion 17g that abuts against the lower attachment member 56 is integrally extended from the lower end of the side wall portion 17b of the partition frame 17. Therefore, it is not necessary to attach the other member for arranging the lower side mounting member 56 to the partition frame 17 on the lower side mounting member 56, so that the number of parts can be reduced.

Next, other embodiments will be described. As shown in Fig. 10, in the present embodiment, the partition frame 17" of the rotary partition 13" is integrally formed into a frame shape having a cross-sectional shape of the front portion 28. Further, the wall thickness of the front surface 28 is formed as a thin film having a degree of damage to the adsorption force of the adsorption surface 16a of the separator 16" which forms the adsorption surface of the door pads 11, 12, and is inside the inner surface. The side is configured with the adsorption surface 16a".

In the assembly of the rotary separator 13", the planar heater 19" or the heat diffuser 20" is pre-fixed between the corner portions 16b" of the partition 16", and the partition 16" is separated from the partition frame The 17" upper opening is inserted into the inside, and the front end of the corner portion 16b" is fitted to the side of the groove 18a" formed in the molded heat insulating member 18", whereby both sides can be combined.

Further, the partition frame 17" is of course not necessarily required to have a cross-sectional shape, and may be covered by a separate film member. According to this configuration, since the partition 16" can be disposed in a state in which it is not visible from the outside, It can be formed from uncoated steel sheets, which can contribute to cost reduction.
