An opening hole 65 is provided so as to face the injection hole 52 and the hole 66 of the rotary partition reinforcing plate 55.

As shown in FIG. 10, the soft bag member 64 is connected to the rotary partition reinforcing plate 55 via the double-sided adhesive 67 between the hole 66 of the rotary partition reinforcing plate 55 and the opening hole 65 of the soft bag member 64. It is fixed. Further, the vicinity of the end portion of the soft bag member 64 is also fixed to the rotary partition reinforcing plate 55 via the double-sided adhesive 68.

The central portion of the double-sided adhesive 67 has a gap as shown in FIG. With such a configuration, when the foam heat insulating material 50 for the rotary partition is filled from the injection hole 52, the foam heat insulating material 50 for the rotary partition is surely filled in the soft bag member 64 (see FIG. 8). ..

The end of the soft bag member 64 is provided with an opening hole for venting air. As a result, unnecessary air during filling and foaming of the foamed heat insulating material 50 for the rotary partition is discharged to the outside from the air vent hole 53 of the outer shell member 47 on the storage chamber side via the seal foam 70 (see FIG. 10). ..

The upper end of the rotary partition 35 is covered with a cap 62 (see FIG. 9).

The cushioning sheet 54 fills and foams the foaming heat insulating material 50 for the rotating partition inside the rotating partition 35, and then closes the injection hole 52 and the air vent hole 53 on the side surface of the storage chamber of the outer member 47 on the storage chamber side. It is pasted on.

In the present embodiment, the rotary partition 35 is not provided with a heating portion.

Next, the action and effect of the refrigerator 100 configured as described above will be described.

The refrigerant compressed by the compressor 23 constituting the refrigeration cycle dissipates heat with a condenser, is depressurized by a capillary tube, absorbs heat with a cooler 20, and returns to the compressor 23 again. The cold air generated by the cooler 20 is supplied from the cooling fan 21 to the refrigerating chamber 14, the switching chamber 15, the ice making chamber 16, the vegetable chamber 17, and the freezing chamber 18 in the refrigerator main body 1 via a duct, and each storage chamber is supplied. Cool to a predetermined temperature.

The refrigerator 100 of the present embodiment includes a dew condensation prevention heater 59 that heats the side surface of the second door 72 on the second door 72 of the double door 7. With such a configuration, the air in the gap between the door end faces of the first door 71 and the second door 72, which is generated when the door is closed, is heated. Therefore, with such a configuration, cold air does not come into contact with the rotary partition 35, and dew condensation on the rotary partition 35 can be suppressed.

As shown in FIG. 5, the gap between the second door 72 on the side not provided with the rotating partition 35 and the rotating partition 35 is the first door 71 on the side provided with the rotating partition 35 and the rotating partition 35. Larger than the gap. With such a configuration, the side surface 321 of the second door 72 tends to have a lower temperature than the side surface 321 of the first door 71. With such a configuration, in the present embodiment, by providing the dew condensation prevention heater 59 on the second door 72, which tends to have a low temperature, it is possible to effectively heat the cold air that comes into contact with the rotary partition 35.

Further, the second door 72 is provided with a dew condensation prevention heater 59 that heats, for example, substantially half of the area on the side surface of the second door 72. With such a configuration, air in a region close to the rotary partition 35 in the space S partitioned by the side surfaces 321 of the first door 71 and the second door 72 and the rotary partition 35 is effectively added. Can be warmed.

Further, the rotary partition body 35 itself is not provided with a heater for preventing dew condensation. With such a configuration, it is possible to prevent a part of the heat of the dew condensation prevention heater from entering the refrigerating chamber 14 through the rotary partition 35 and raising the temperature in the refrigerating chamber 14.

Further, a gasket having a low thermal conductivity is provided between the second door 72 and the rotary partition 35. With such a configuration, it is possible to prevent a part of the heat of the dew condensation prevention heater 59 provided on the second door 72 from being transferred to the rotary partition 35.

Further, the heating portion 591 is divided into a plurality of portions. Further, the heating portion 591 has different watt densities for each of the plurality of portions. With such a configuration, the air in the gap between the end faces of the first door 71 and the second door 72 of the double door 7 can be efficiently heated according to the temperature distribution in the refrigerator compartment 14. As a result, the power consumption of the dew condensation prevention heater 59 can be reduced.

In the present embodiment, the dew condensation prevention heater 59 is provided over substantially the entire length of the double door 7 in the longitudinal direction. Further, in the present embodiment, the watt density of each portion of the heating portion (heater) 591 is set so that the temperature of the lower portion of the double door 7 is the highest. However, the refrigerator 100 of the present embodiment is not limited to such a configuration, and for example, a dew condensation prevention heater 59 may be provided in a region substantially half of the lower part of the double door 7 in the longitudinal direction. With such a configuration, it is possible to increase the heating amount of the lower part of the double door 7 without finely setting each watt density of the heating portion (heater) 591. With such a configuration, it is possible to use an inexpensive heater for the dew condensation prevention heater 59. Of the door outer frame 32, at least the thermal conductivity of the side surface 321 is determined by the outer shell of the rotary partition 35 (storage chamber side outer shell member 47 or the outside air side outer shell member 48) or the heat insulating material (molded heat insulating member 49, Alternatively, it is higher than the thermal conductivity of the foamed heat insulating material 50) for the rotary partition. With such a configuration, the heat of the dew condensation prevention heater 59 can be efficiently conducted to the side surface 321. Therefore, with such a configuration, the air that comes into contact with the rotary partition 35 can be effectively heated.

Further, the thermal conductivity of the outer shell of the rotary partition 35 (the outer shell member 47 on the storage chamber side or the outer shell member 48 on the outside air side) or the heat insulating material (the molded heat insulating member 49 or the foamed heat insulating material 50 for the rotary partition body). Is lower than the thermal conductivity of the door outer frame 32. With such a configuration, it is possible to prevent a part of the heat of the dew condensation prevention heater 59 provided on the second door 72 from being transmitted to the refrigerating chamber 14 via the rotary partition 35.

Further, the rotary partition body 35 is configured by filling the foam heat insulating material 50 for the rotary partition body between the storage chamber side outer shell member 47 and the outside air side outer shell member 48 via the soft bag member 64 which is an intervening member. Has been done. With such a configuration, the heat insulating property of the rotary partition 35 is remarkably higher than that in which expanded polystyrene is used as the heat insulating material. Therefore, it is possible to effectively suppress the heat of the outside air that tends to enter the refrigerating chamber 14 through the rotating partition 35.

In the present embodiment, the rotary partition 35 is described by taking as an example a form in which the foam heat insulating material 50 for the rotary partition is filled inside the outer shell of the rotary partition 35 via a soft bag member 64, but the present invention is limited to this embodiment. Instead, it may be a rotary partition body in which styrofoam is provided inside the outer shell via a soft bag member 64.

Further, in the rotary partition 35, when the foam heat insulating material 50 for the rotary partition is vertically elongated and filled, in the conventional configuration, the storage chamber side outer member 47 and the outside air side outer member 48 are fitted by the foaming pressure. The foamed heat insulating material 50 for the rotary partition easily leaks from the mating portion. However, in the present embodiment, the rotary partition 35 is a foamed heat insulating material for the rotary partition between the storage chamber side outer member 47 and the outside air side outer member 48 via the soft bag member 64 which is an intervening member. 50 is filled and configured. With such a configuration, leakage of the foamed heat insulating material 50 for the rotary partition from the portion where the storage chamber side outer shell member 47 and the outside air side outer shell member 48 are fitted can be reliably suppressed. Therefore, with such a configuration, it is possible to obtain the rotary partition body 35 having improved heat insulating properties.

Further, the soft bag member 64, which is an intervening member, arranged between the storage chamber side outer shell member 47 and the outside air side outer shell member 48, constitutes the storage foam heat insulating material 50 for the rotary partition body and the rotary partition body 35. The adhesive strength between the chamber-side outer shell member 47 and the outside air-side outer shell member 48 is relaxed, and warpage and deformation due to the difference in cold and hot temperatures of the rotary partition 35 can be suppressed.

Further, a ring-shaped seal foam 69 is arranged between the injection hole 52 of the outer shell member 47 on the storage chamber side and the hole 66 of the rotary partition reinforcing plate 55. Further, a rectangular seal foam 70 is arranged between the air vent hole 53 and the hole 57. Further, the storage chamber side outer shell member 47 and the rotary partition reinforcing plate 55 are fixed by the claws 56. With such a configuration, it is possible to more reliably improve the filling property of the foamed heat insulating material 50 for the rotary partition body 35 into the rotary partition body 35 via the soft bag member 64.

Further, the soft bag member 64 interposed in the space between the storage chamber side outer shell member 47 and the outside air side outer shell member 48, which constitutes the outer shell of the rotary partition body 35, rotates with the injection hole 52 of the storage chamber side outer shell member 47. An opening hole 65 is provided so as to face the hole 66 of the partition body reinforcing plate 55. The soft bag member 64 is fixed to the rotary partition reinforcing plate 55 via the double-sided adhesive 67 between the hole 66 of the rotary partition reinforcing plate 55 and the opening hole 65 of the soft bag member 64. With such a configuration, it is possible to more reliably improve the filling property of the foamed heat insulating material 50 for the rotary partition body 35 into the inside of the rotary partition body 35 via the soft bag member 64.
