In FIG. 6, the dew condensation preventing heater 59 includes a heating portion (heater) 591, a lead wire (electric wire) 592 for supplying electricity to the heating portion (heater) 591, and a heating portion 591 and a lead wire 592. Switching parts 593a and 593b for electrical connection are provided.

  The switching parts 593a and 593b are arranged near the center of the double door 7 in the longitudinal direction. The heating portion 591 extends above the switching portion 593a along the longitudinal direction (the direction indicated by the arrow in FIG. 6) of the double door 7, and is folded near the upper end of the double door 7. The heating portion 591 is further disposed over substantially the entire length in the longitudinal direction of the door-opening door 7 toward the lower end of the door-opening door 7, is folded back near the lower end of the door-opening door 7, and is extended in the longitudinal direction of the door-opening door 7. It extends upward again along the direction and is connected to the switching portion 593b. The lead wire 592 is arranged so as to extend one above each of the switching portions 593a and 593b along the longitudinal direction of the double door 7 and above the switching portion 593a.

  More specifically, as shown in FIG. 6, the heating portion 591 is connected to the portion d having a watt density W1 and a length L1 arranged on the lead wire 592 side of the switching portion 593a, and is connected to the portion d in the upward direction. It has an inverted U-shaped part e having a length L2 and an extended watt density W2. The heating portion 591 is further connected to the portion e and extends downward in parallel with the portion d and has a length L3 with a watt density W3, and a watt density connected to the portion f and provided alongside the switching portions 593a and 593b.

With such a configuration, the outer surface of the side surface 321 has a substantially uniform temperature. For this reason, the air near the space S also has a substantially uniform temperature in the vertical direction, and the air near the space S can be efficiently heated. This makes it possible to reliably suppress the dew condensation on the rotary partition body 35 while reducing the power consumption of the dew condensation prevention heater 59.

The rotary partition body reinforcing plate 55 has a hole 66 in a portion facing the injection hole 52 provided in the storage room side outer member 47. Further, a hole 57 is provided facing the air vent hole 53.

  As shown in FIG. 10, a ring-shaped seal form 69 is provided between the injection hole 52 of the storage chamber side outer member 47 and the hole 66 of the rotary partition reinforcing plate 55, and the air vent hole 53 and the hole 57 are provided. Between them, a rectangular seal form 70 is provided.

  As shown in FIGS. 9 and 10, the soft bag member 64 interposed in the space between the storage room side outer member 47 and the outside air side outer member 48 constituting the outer wall of the rotary partition body 35 includes the storage room side outer member 47. An opening hole 65 is provided to face the injection hole 52 and the hole 66 of the rotary partition body reinforcing plate 55.

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

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

  Note that an end of the soft bag member 64 is provided with an opening for venting air. Thereby, unnecessary air at the time of filling and foaming the rotary partition body foaming heat insulating material 50 is discharged to the outside from the air vent hole 53 of the storage room side outer member 47 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 lower end of the rotary partition 35 is closed by fitting the lower side of the opening of the storage room side outer member 47 and the lower side of the opening of the outside air side outer member 48.

  The buffer sheet 54 is attached to the storage chamber side outer member 47 so as to cover at least the injection hole 52 and the air vent hole 53. The buffer sheet 54 closes the injection hole 52 and the air vent hole 53 on the storage chamber side surface of the storage chamber side outer member 47 after the rotary partition body 35 is filled and foamed with the rotary partition body foam insulating material 50. Pasted in.

  In this embodiment, the rotary partition 35 is not provided with a heating unit.

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

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

  The refrigerator 100 of the present embodiment includes a dew condensation preventing heater 59 for heating 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 respective door end surfaces of the first door 71 and the second door 72 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 the dew condensation of the rotary partition 35 can be suppressed.

  As shown in FIG. 5, the gap between the second door 72 on the side without the rotary partition 35 and the rotary partition 35 is the first door 71 on the side with the rotary partition 35 and the rotary partition 35. Larger than the gap. With such a configuration, the temperature of the side surface 321 of the second door 72 tends to be lower than that of the side surface 321 of the first door 71. With such a configuration, in the present embodiment, since the dew condensation preventing heater 59 is provided in the second door 72 that is likely to be at a low temperature, it is possible to effectively heat the cold air that touches the rotary partition 35.

  In addition, the second door 72 includes a dew condensation preventing heater 59 for heating, for example, a substantially half area inside the refrigerator, of the side surface area. With such a configuration, in the space S defined by the side surface 321 of each of the first door 71 and the second door 72 and the rotary partition 35, air in a region near the rotary partition 35 is effectively added. You can warm up.

  Further, the rotary partition 35 itself is not provided with a dew condensation preventing heater. With such a configuration, it is possible to prevent a part of the heat of the dew condensation prevention heater from entering the refrigerator compartment 14 via the rotary partition 35 and increasing the temperature inside the refrigerator compartment 14.

  Further, a gasket having a low thermal conductivity is provided between the second door 72 and the rotary partition body 35. With such a configuration, a part of the heat of the dew condensation prevention heater 59 provided on the second door 72 can be suppressed from being transmitted 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 of a 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. Thereby, 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. In the present embodiment, the watt density of each portion of the heating portion (heater) 591 is set so that the temperature at 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. For example, the dew condensation prevention heater 59 may be provided in a substantially half area below the double door 7 in the longitudinal direction. With such a configuration, the amount of heating at the lower portion of the double door 7 can be increased without finely setting each watt density of the heating portion (heater) 591. With such a configuration, an inexpensive heater can be used as the condensation prevention heater 59. The thermal conductivity of at least the side surface 321 of the door outer peripheral frame 32 is determined by the outer shell (the storage room outer shell member 47 or the outer air side outer member 48) of the rotary partition body 35 or the heat insulating material (the molded heat insulating member 49, Or, it is higher than the thermal conductivity of the foamed heat insulating material for a rotary partition 50). With such a configuration, the heat of the condensation prevention heater 59 can be efficiently conducted to the side surface 321. Therefore, with such a configuration, the air in contact with the rotary partition 35 can be effectively heated.

  In addition, the thermal conductivity of the outer shell of the rotary partition 35 (the storage room side outer member 47 or the outer air side outer member 48) or the heat insulating material (the molded heat insulating member 49 or the foam heat insulating material 50 for the rotary partition). Is lower than the thermal conductivity of the door outer peripheral frame 32. With such a configuration, part of the heat of the dew condensation prevention heater 59 provided on the second door 72 can be suppressed from being transmitted to the refrigerator compartment 14 via the rotary partition 35.

  Further, the rotary partition 35 is configured such that a foam insulating material 50 for a rotary partition is filled between the storage room side outer member 47 and the outside air side outer member 48 via a soft bag member 64 as an intervening member. Have been. With such a configuration, the heat insulating property of the rotary partition body 35 is much higher than that of the rotary partition body 35 in which styrofoam is used. Therefore, it is possible to effectively suppress the outside air heat that tends to enter the refrigerator compartment 14 through the rotary partition 35.

  In the present embodiment, an example has been described in which the rotatable partition body 35 is filled with the rotatable partition foam insulating material 50 via the soft bag member 64 inside the outer shell, but is not limited to this mode. Instead, a rotary partition body provided with styrofoam via the soft bag member 64 inside the outer shell may be used.

  Further, in the rotary partition 35, when the foam insulating material 50 for a rotary partition is elongated vertically, the storage chamber side outer member 47 and the outside air side outer member 48 are fitted by the foaming pressure in the conventional configuration. It is easy for the foamed heat insulating material for a rotary partition body 50 to leak out from the portion where it is fitted. However, in the present embodiment, the rotary partition 35 is provided between the storage room side outer member 47 and the outside air side outer member 48 via the soft bag member 64 as an intervening member, and the rotary partition body foam insulation material. 50 are filled. With such a configuration, it is possible to reliably suppress the leakage of the foamed heat insulating material 50 for the rotary partition from the portion where the storage room side outer member 47 and the outside air side outer member 48 are fitted. Therefore, with such a configuration, it is possible to obtain the rotary partition body 35 with improved heat insulation.

  In addition, the flexible bag member 64 serving as an intervening member disposed between the storage room side outer member 47 and the outside air side outer member 48 stores the rotatable partition foam insulating material 50 and the rotatable partition 35. Adhesion strength between each of the room-side outer member 47 and the outside-air-side outer member 48 is reduced, and warpage and deformation due to a difference in cooling and heating temperatures of the rotary partition 35 can be suppressed.

  A ring-shaped seal foam 69 is arranged between the injection hole 52 of the storage chamber side outer member 47 and the hole 66 of the rotary partition body reinforcing plate 55. A rectangular seal form 70 is disposed between the air vent hole 53 and the hole 57. The storage room side outer member 47 and the rotary partition body reinforcing plate 55 are fixed by 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 into the rotary partition 35 via the soft bag member 64.

However, the intervening member is not limited to this, and may be, for example, a blow-molded member, a release material applied, or an adhesive such as a release tape.

  In the present embodiment, the storage chamber side outer member 47 and the outside air side outer member 48 are formed of a resin having low thermal conductivity, and the example in which the magnet is embedded inside the rotary partition 35 has been described. However, the present invention is not limited to this, and a magnetized metal plate may be provided inside the rotary partition 35 instead of the magnet 58. Further, the outside air-side outer member 48 may be formed of a metal plate.

  In this case, the magnet arrangement space inside the rotary partition 35 can be filled with the foam insulating material 50 for the rotary partition via the soft bag member 64, so that the heat insulating property is improved and the strength of the rotary partition 35 is increased. be able to. In this case, by using an iron plate for the storage room side outer member, the rotary partition body reinforcing plate 55 provided on the storage room side outer member 47 can be unnecessary or thinned, and the optimal balance between heat insulation, strength and cost can be achieved. Can be achieved.

  Further, in the present embodiment, the form in which the molded heat insulating member 49 made of styrene foam is provided near the hinge member at the upper end of the rotary partition body 35 is described as an example, but the present invention is not limited to this. Almost the entire area inside the rotary partition 35, including the vicinity of the hinge members at the upper and lower ends of the partition 35, may be filled with the foam insulating material 50 for the rotary partition via the soft bag member 64.

  In this case, it is possible to obtain effects such as an improvement in heat insulation performance and an improvement in strength due to an increase in the filling rate of the urethane foam, and a cost reduction by eliminating the need for the molded heat insulation member 49 made of styrene foam.
