  An embodiment of a refrigerator according to the present invention will be described with reference to FIGS. It should be noted that the present invention is not limited to the present embodiment, and various modifications and additions can be made in consideration of known techniques and technical common knowledge of those skilled in the art.

  FIG. 1 is a front outline view of the refrigerator of the present embodiment. FIG. 2 is a cross-sectional view of the refrigerator shown in FIG. 3 is a BB cross-sectional view of the refrigerator shown in FIG.

  As shown in FIG. 2, the refrigerator 1 of this embodiment is the storage room of the refrigerator temperature zone of about 3-5 degreeC from the upper part in the refrigerator compartment 2, the upper stage freezer room 3, the lower stage freezer room 4, and the vegetable compartment 5. As shown in FIG. The upper freezer compartment 3 and the lower freezer compartment 4 are storage rooms in a freezing temperature zone of approximately −18 ° C.

  The refrigerator compartment 2 is provided with double door type refrigerator compartment doors 6 and 7 that divide the front side into left and right. The upper freezer compartment 3, the lower freezer compartment 4, and the vegetable compartment 5 are each provided with a drawer-type upper freezer compartment door 8, a lower freezer compartment door 9, and a vegetable compartment door 10. Further, packings 17 and 18 (seal members) (see FIG. 3) are provided on the surface of each door on the storage chamber side along the outer edge of each door, and the outside air enters the storage chamber when each door is closed. , And the cool air leakage from the storage room is suppressed.

  Reference numeral 11 denotes a cooler chamber. The cooler chamber 11 includes a cooler 12 that constitutes a refrigeration cycle, a cooling fan 13 that forcibly circulates cold air cooled by the cooler 12 to the refrigerator compartment 2, the freezer compartments 3, 4, and the like. Is provided.

  Reference numerals 14 and 15 denote fixed partitions. In the refrigerator 1 of the present embodiment, the refrigerator compartment 2 and the freezer compartment 3 (see FIG. 2) are separated by an upper heat insulating partition wall 14 through a heat insulating wall, and the lower heat insulating partition wall. The wall 15 separates the lower freezer compartment 4 from the vegetable compartment 5 in an adiabatic manner. Thereby, each chamber is maintained at a predetermined temperature.

  Reference numeral 16 denotes a rotating partition. The rotary partition 16 constitutes a packing receiving surface of a double door (right refrigeration chamber 6, left refrigeration chamber 7) provided so as to close the opening in front of the refrigeration chamber 2. The rotating partition 16 is attached to the left refrigerator compartment door 7. And the rotation partition 7 rotates from the position of a continuous line to the position of a broken line as FIG. 3 by the guide member (not shown) provided in the refrigerator main body 1 side which comprises the refrigerator compartment 2. As shown in FIG. Thereby, the rotation partition 16 comprises the receiving surface of the packings 17 and 18 (seal member) provided in the right refrigerator compartment door 6 and the left refrigerator compartment door 7, respectively. Further, the rotating partition 16 is formed with a thin heat insulating wall as shown in FIG. This is also for reducing the gap width dimension (W1 in FIG. 3) of the front door of the rotating partition 16, that is, the right refrigerator compartment door 6 and the left refrigerator compartment door 7, and in the refrigerator 1 of the present embodiment, The gap width dimension W1 between the rotating partition part front doors is 6 mm. Moreover, the gap depth dimension (dimension D in FIG. 3) from the door front edge to the surface of the rotating partition 16 is set to three times W1 or more, and the refrigerator 1 of this embodiment has D = 60 mm as an example.

  Further, the L1 dimension (see FIG. 4) in the vertical direction of the rotating partition 16 is configured to be shorter than the height dimension L2 of the refrigerator compartment 2 because of the structure that rotates in the refrigerator compartment 2. For this reason, a gap 21 corresponding to L2-L1 is formed between the rotating partition 16 and the inner box 29 constituting the refrigerator compartment 2 in the vertical direction. Reference numerals 19 and 20 denote flange-shaped packings (ridge-shaped sealing members) that protrude from the bases of the packings 17 and 18 and are integrally formed on the upper and lower ends, respectively. As shown in FIG. 4, the packings 19 and 20 are provided to close the gap 21 formed by L2-L1.

  Next, referring to FIG. 5, the rotating partition 16 will be described in detail. In the figure, 16 is a rotating partition, and this rotating partition 16 includes a box 22 made of resin, a plate-like metal member 23 (a plate-like metal member constituting a seal member receiving surface), and a heat insulating material. 24 (expanded polystyrene), a dew condensation prevention heater 25, and the like. And the box 22 and the plate-shaped metal member 23 are comprised so that the thickness (T dimension) of the rotation partition 16 may be set to about 20-30 mm as an example.

  Moreover, the plate-shaped metal member 23 is made of a thin steel plate having a plate thickness of 0.4 to 1.0 mm as an example. Usually, the plate-like metal member 23 is formed by painting after shaping with a press machine or the like. The plate-like metal member 23 serves as a receiving surface for the packings 17 and 18 incorporating a permanent magnet.

  Here, since the rotation partition 16 itself rotates, the heat insulation layer cannot be made too thick. Therefore, by the heat conduction from the box body 22 cooled by the cold air in the refrigerator compartment 2, the outdoor plate-like metal member 23, the packings 17 and 18, the right refrigerator compartment door side portion 27, and the left refrigerator compartment door side portion. There is a risk that 28 will be condensed at a temperature lower than the outside air temperature.

  For this reason, a dew condensation prevention heater 25 composed of a cord heater 25a, an aluminum foil 25b, and the like is disposed in the box 22 and on the back side of the plate-like metal member 23, and the dew condensation prevention heater 25 is heated. Thus, condensation on the surface of the plate-shaped metal member 23, the packings 17 and 18, the right refrigerator compartment door side face portion 27, and the left refrigerator compartment door side face portion 28 is prevented.

  On the other hand, the temperature of the refrigerator compartment 2 gradually increases from the central portion toward the upper portion, and the temperature of the rotating partition 16 also increases gradually from the central portion toward the upper portion. Among the rotating partition 16, the plate-like metal member 23 has high heat conduction and is unlikely to generate temperature unevenness in the vertical direction, but the packings 17 and 18, the right refrigerator compartment door side portion 27, and the left refrigerator compartment door side surface. Since the portion 28 has lower heat conduction than the plate-like metal member 23, the temperature unevenness in the vertical direction is likely to occur, and local condensation may occur from the central portion to the lower portion.

  In the structure of the present embodiment, a plate shape is used so that heat of the dew condensation prevention heater 25 is not excessively transferred from the central portion to the upper portion of the packings 17 and 18, the right refrigerator compartment door side portion 27, and the left refrigerator compartment door side portion 28. The contact area between the metal member 23 and the packings 17 and 18 is reduced. And the heat | fever of the dew condensation prevention heater 25 concentrates from the center part of packing 17,18, the right refrigerator compartment door side part 27, and the left refrigerator compartment door side part 28 to the lower part, and generation | occurrence | production of local dew condensation occurs. And the input of the dew condensation prevention heater can be reduced.

  Specifically, a cross-sectional view from the central part to the lower part of the rotating partition 16 is shown in FIG. 5, and a cross-sectional view from the central part to the upper part is shown in FIG. From the center part of the rotating partition 16 to the lower part, the contact width w1 (see FIG. 5) between the plate-like metal member 23 and the packings 17 and 18, and from the center part of the rotating partition 16 to the lower part, the plate-like metal member. 23 and the contact width w2 of the packings 17 and 18 (see FIG. 6), and w1> w2, so that the packings 17 and 18, the right refrigerator compartment door side portion 27, and the left refrigerator compartment door side portion 28 The heat of the dew condensation prevention heater 25 is not conducted excessively from the central portion to the upper portion.

  Next, the contact surface between the box 22 and the plate-like metal member 23 will be described with reference to FIG. As described above, the plate-like metal member 23 on the outdoor side is cooled by the heat conduction from the box 22, and therefore the heat conduction from the box 22 is reduced by reducing the contact area between the box 22 and the plate-like metal member 23. The amount can be reduced and the temperature of the plate-like metal member 23 can be raised.

  Further, the side surface portion 29 of the plate-like metal member 23 is fitted by the projection portion of the box 22 and the resin projection fitting portion 30. The width W2 of the resin protrusion fitting portion 30 is about 8 mm, and a fitting hole of about 4 mm is opened at the center. Therefore, the bent part has a width of about 2 mm and maintains its shape. The width W3 of the plate-shaped metal member side surface portion 29 is about 6 mm, and the bent portion width of about 2 mm can be obtained by providing the centering portion 31 with a width direction of about 2 mm in the center. The shape of the side surface portion 29 can be maintained. By adopting this shape, cooling from the box 22 can be suppressed, and heat penetration from the dew condensation prevention heater 25 into the refrigerator compartment 2 can be suppressed. From the above, it is possible to reduce the input of the dew condensation prevention heater.

  However, by providing the cutout portion 31 of the plate-like metal member 23 on the plate-like metal member side surface portion 29, the fitting force between the box 22 and the plate-like metal member 23 is reduced, and the rotating partition 16 can be destroyed. Sex is conceivable.

  The box 22 is shaped so that the two side surfaces and the bottom surface are perpendicular to each other. And the box 22 is also cooled by the heat conduction from the refrigerator compartment 2, and two side parts shrink | contract inside while being minute. Thus, the rotary partition 16 can be configured by strengthening the fitting between the box 22 and the plate-like metal member 23.

  In order to improve the fitting force between the box 22 and the plate-like metal member 23, a slit 26 is provided in the box 22 as shown in FIG. The slit 26 is provided over the entire length at the center of the back side (storage chamber side) inside the box body 22 (see FIGS. 5, 6, and 8). The fitting between the body 22 and the plate-like metal member 23 is strengthened, and the configuration of the rotating partition 16 can be maintained.

  Since it is comprised as mentioned above, the shaping | molding intensity | strength of the plate-shaped metal member 23 and the intensity | strength of the rotation partition 16 are fully ensured, and the refrigerator excellent in energy saving performance can be provided.

  As described above, the configuration of the present embodiment includes a heat insulating box having a storage chamber in which an opening is formed in the front, a first door that opens and closes a part of the opening, and the opening adjacent to the first door. A second door that opens and closes the other part, and a rotating partition that is provided on the first door and rotates to seal a gap between the first door and the second door The rotating partition includes a dew condensation prevention heater that suppresses the occurrence of dew condensation, and a plate metal member that contacts the dew condensation prevention heater, and the plate metal member has a different width in the vertical direction. .

  That is, the temperature unevenness of the rotating partition is suppressed, the input of the dew condensation prevention heater provided in the rotating partition is reduced, and the temperatures of the first door, the second door, and the rotating partition to be packed are dew points. It is possible to keep above.

  Moreover, a slit is provided in the center of the back surface of the box constituting the rotating partition. As a result, the two side surfaces constituting the box body are contracted inward to strengthen the fitting between the box body and the plate-like metal member, and the configuration of the rotating partition body can be maintained.
