The left and right first and second doors that open and close the front opening of the main body and the inner surface of the first side edge of the first door are rotatably supported inward and outward. It extends vertically along the front edge of the door of the door, and when it rotates outward, it protrudes from the front edge of the door along the inner surface of the first door and turns inward. A columnar closing member that retreats from the front edge of the door when moving, and a pair of upper and lower guide mechanisms that rotate the closing member outward, and when the doors are closed, the inner surfaces of both doors are The front side of the front opening of the cabinet body is brought into contact with the front surface of the peripheral edge via a seal member to close the periphery of the front opening, and the front A double-sided door configured such that the front surface of the closing member is brought into contact with the inner surfaces of the front edge portions of the doors via a seal member so as to close the vertical gap between the opposite front edge portions of the doors. In the type refrigerator, each guide mechanism is provided at a substantially central part of each of the upper and lower edges of the front opening of the main body and is located at a predetermined distance from the front surface of each edge part, and left and right along the front surface. First and second guide portions each having a guide surface extending a predetermined length in the direction, and sliding on the guide surfaces of the first guide portions provided at the upper and lower end portions of the closing member when the first door is closed. The closing member is rotated outward while in contact with the inner surface facing the guide surface and facing the guide surface, and protrudes a predetermined length in each of the upper and lower directions, and when the closing member is rotated outward.

  However, in the case shown in Patent Document 1, there has been a risk that the hook-shaped portion may be damaged by long-term use and the sealing performance may be deteriorated. Further, each time the door is opened and closed, the hook-shaped portion comes into contact with the other door (the one that is not opened and closed) and generates a rubbing sound, which may cause discomfort to the user.

  Moreover, if it is the gap blockage structure of patent document 2, if the door main body which attached the rotation partition will incline and fall with the weight of a storage thing, for example, a beer bottle, a 2L plastic bottle, etc., a rotation partition will also be together Go down. For this reason, the rear surface of the elastic body cannot be pushed up by the inclined surface provided on the rotating partition side, and the elastic body may not be able to close the gap.

  In addition, there is a possibility that dew phenomenon or freezing of dew condensation water, indoor cold air leakage, etc. may occur through the gap.

  In addition, in Patent Document 3, the closing member is not folded until approximately 90 degrees, and is tilted to approximately 50 to 70 degrees, and the first guide member (door side) is moved to the second guide on the main body side. The closing member that is in contact with the member and tilted is opened (a position parallel to the door). Therefore, the width of the first guide member is required to be the same size as the width of the closing member, and a gap that changes to the gap size is formed at both ends of the mating portion of the first guide member and the second guide member, This is covered with a soft sealing material. In other words, the first guide member and the second guide member cannot be said to have a structure in which the gap is eliminated.

  Furthermore, it is a structure that is not suitable for a refrigerator that has a door pocket or the like and that emphasizes expansion of the internal volume. That is, in this structure, it is difficult to apply the present invention to a refrigerator in which the width of the closing member is narrow and the size between the doors is narrow and the closing member is required to be folded 90 degrees.

  In the case of the one disclosed in Patent Document 4, the upper and lower surface guides are obstructive when the stored food is taken in and out of the refrigerator compartment. Further, since the upper and lower outer peripheries of the rotating partition are in contact with the upper and lower guide surfaces, the rotating partition is not smoothly rotated. Furthermore, if a convex part is provided, it will lead to formation of a gap dimension.

  Then, an object of this invention is to provide the refrigerator which prevented the dew, the cold air leak, the penetration | invasion of external air, etc. which generate | occur | produce by the clearance gap between doors.

  In order to solve the above problems, for example, the configuration described in the claims is adopted. The present application includes a plurality of means for solving the above-described problems. For example, the first door and the second door adjacent to each other, and a rotating partition provided rotatably on the first door. And a receiving seat provided on the refrigerator main body side for rotating the rotating partition, and in a refrigerator in which a gap is formed between the rotating partition and the receiving seat, the front edge of the receiving seat A concave receiving portion provided; and a shielding plate that projects from the rotating partition toward the receiving seat to shield the gap, and moves within the receiving portion when the first door is rotated, The shielding plate has a cross-sectional shape that follows the shape of the receiving portion, and is provided so as to be on the same plane as the front surface of the rotating partition. The intermediate position of the receiving portion and the shielding plate is the first position It is located in the first door side rather than the middle position of the door and the second door.

  ADVANTAGE OF THE INVENTION According to this invention, the refrigerator which prevented the dew generated by the clearance gap between doors, a cold air leak, the penetration | invasion of external air, etc. can be provided.

  First, in FIG. 1, 1 is a refrigerator main body. This refrigerator body 1 has a refrigerator compartment 3 having a double door type first door 2a and a second door 2b from above, and a first freezer compartment 101, an ice making compartment 102 adjacent to the left and right in the lower part thereof, Furthermore, it is a general refrigerator having a second freezer compartment 103 at the bottom and a vegetable compartment 104 at the bottom. Note that the layout of the storage room is not limited to this, and a refrigerator in which the vertical and horizontal arrangements are appropriately changed may be used.

  Next, the first door 2a and the second door 2b will be described. The 1st door 2a and the 2nd door 2b are attached to the refrigerator main body 1 with the door hinges 4a and 4b shown in FIG. And between the 1st door 2a and the 2nd door 2b, it forms so that the dimension L between doors may be 10 mm or less on a design as shown in the figure.

  The inter-door dimension L is set to a dimension that does not allow the end surfaces of both doors to contact even when the first door 2a and the second door 2b are opened simultaneously. In other words, both doors are set so that the turning trajectory of the doors does not exceed the center line P (see FIG. 2) when the doors are turned.

  Reference numeral 5 denotes a rotating partition. The rotary partition 5 is attached to the side wall of the door inner plate 6 of the first door 2a with a rotary partition hinge 7 so as to be rotatable about a shaft 9. And this rotation partition 5 comprises the receiving surface of the gaskets 8a and 8b attached to the surface at the side of the storage chamber of the 1st door 2a and the 2nd door 2b.

  As shown in FIG. 2, when the first door 2a and the second door 2b close the refrigerator compartment 3, the rotary partition 5 is in the position of the solid line, and at least the first door 2a is opened. It is provided so as to be rotated by a spring 15 which is an elastic body, a guide pin 11 which will be described later, and a guide groove 13 so as to be in the position of the chain line (the position of the rotating partition 5 ').

  A receiving seat 10 includes a guide pin 11. The receiving seat 10 is attached to the ceiling surface and the front end of the inner box 12 constituting the refrigerator compartment 2. Further, the guide pin 11 slides in a guide groove 13 provided at the end of the rotary partition 5 to rotate the rotary partition 5 between a solid line position and a chain line position.

  Reference numerals 14a and 14b denote flanges provided on the gaskets 8a and 8b, respectively. The flanges 14a and 14b are formed at the time of extrusion molding of the gaskets 8a and 8b. In the longitudinal direction other than the flanges 14a and 14b (see FIG. 3), the central part is extruded and then used by a press machine or the like. Cutting and removing. The overlapping portions of the hook-like portions 14a and 14b block the gap G (shaded portion in FIG. 3) between the end of the rotating partition 5 and the receiving seat 10.

  Reference numeral 16 a denotes an upper end member provided at the upper end of the rotary partition 5. The upper end member 16a is provided at the upper end of the rotary partition 5 and is combined with a main body 17 constituting the outline of the rotary partition 5 as shown in FIG. 4 to form a container-like partition box. Moreover, the lower end member 16b is similarly provided in the lower end part of the rotation partition 5 (refer FIG. 6). A metal plate 18 (for example, a thin iron plate) on which the magnets on the gaskets 8a and 8b side are magnetized is provided on the surface of the rotary partition 5. Further, a heat insulating material 19 is filled in the rotating partition 5 configured in a container shape. Further, a dew condensation prevention heater 20 (heating means) is provided on the back side (the heat insulating material 19 side) of the metal plate 18.

  As described above, the rotary partition 5 includes the upper and lower upper end members 16a, the lower end member 16b, the main body 17 constituting the outer shell, the metal plate 18, the dew condensation prevention heater 20, the heat insulating material 19 and the like.

  Reference numeral 21 denotes a shielding plate. The shielding plate 21 is formed so as to protrude from the upper end member 16a and the lower end member 16b constituting the rotary partition 5 to the receiving seat 10 side. The surface of the shielding plate 21 is positioned in the same plane as the metal plate 18 on the rotating partition 5 side when the first door 2a is closed.

  And as shown in FIG. 3, it is desirable to form the width dimension W1 of the shielding board 21 a little larger than the dimension W2 between gaskets 8a and 8b. Moreover, the height dimension H1 is formed in the height which wraps to the concave receiving part 22 formed in the receiving seat 10 mentioned later. The shielding plate 21 may be provided only above the rotating partition 5 or may be provided below as shown in FIG.

  A concave receiving portion 22 is provided at the front edge of the receiving seat 10. When the first door 2a is rotated (when the rotary partition 5 is rotated), the shielding plate 21 is displaced in the receiving portion 22, and when the first door 2a is closed, as shown in FIG. The gap between the upper end of the partition 5 and the receiving seat 10) is closed. In other words, the width dimension, the height dimension, and the depth dimension of the receiving portion 22 are formed slightly larger than the width dimension W1, the height dimension H1, and the thickness dimension of the shielding plate 21, and even if there is some deformation. The shielding plate 21 is configured in a shape that can be displaced within the receiving portion 22 without difficulty.

  Further, when the shielding plate 21 is housed in the receiving portion 22, the surface of the receiving portion 22 and the outer peripheral surface of the shielding plate 21 come into contact with each other and can be sealed so as to suppress gas movement. In other words, the outer diameter of the shielding plate 21 and the inner diameter of the receiving portion 22 are formed to have a substantially common cross-sectional shape.

  Thereby, the cold air leak from the overlap part of the shielding board 21 and the receiving part 22 becomes the minimum. Furthermore, you may employ | adopt the structure which covers the overlap part of the shielding board 21 and the receiving part 22 with the gaskets 8a and 8b and the hook-shaped parts 14a and 14b. The same applies to the gap G between the upper end of the rotary partition 5 and the receiving seat 10. Further, the upper and lower receiving seats 10 themselves are small and simple in shape.

  The shielding plate 21 may be made of elastically deformable rubber so that the shielding plate 21 itself is deformed in the receiving portion 22 to the side opposite to the receiving portion 22. That is, in order to improve the sealing performance of the overlapping portion of the shielding plate 21 and the receiving portion 22, the shielding plate 21 is slightly deformed to the opposite side of the receiving portion 22 in order to reduce the amount of depression on the receiving portion 22 side. Can be considered. In this case, the shielding plate 21 is not integrated with the resin end piece but is provided separately. In this case, a sufficient contact surface can be secured between the surface of the receiving portion 22 and the outer peripheral surface of the shielding plate 21, and sealing is ensured. In other words, the shield plate 21 is elastically deformed and warped not on the guide groove 13 side but on the side opposite to the guide groove 13, thereby reducing the size of the shield plate 21 entering the receiving portion 22 side. In other words, when the rotary partition 5 rotates, the shape of the shielding plate 21 itself is deformed so as to absorb the dimensional error of the rotation locus drawn by the shielding plate 21, and the shielding plate 21 is temporarily outside the receiving portion 22. Displace. Thereby, compared with what does not change the width dimension of the shielding board 21, since the shielding board 21 can be made wide, it is also possible to eliminate the hook-shaped part by the side of a gasket.

  Next, the shielding plate 21 and the receiving portion 22 will be described with reference to FIG. The shielding plate 21 is provided so as to protrude above the guide groove 13 on the upper surface of the upper end member 16a. Further, when the rotating partition 5 is rotated, the shielding plate 21 is rotated along a locus along the outer shape of the shielding plate 21 with the receiving portion 22.

  Accordingly, the receiving portion 22 has a shape that matches the locus drawn by the shielding plate 21. Thereby, the cold air leak from the overlap part of the shielding board 21 and the receiving part 22 which block | closes the clearance gap G becomes the minimum.

  The shielding plate 21 is about half the width of the upper end member 16a and has a thickness of 10 mm or less. The receiving portion 22 has a size for receiving the shielding plate 21 and a cross-sectional shape substantially the same as that of the shielding plate 21.

  Further, the gap G between the upper end of the rotary partition 5 and the receiving seat 10 is closed with the shielding plate 21. Further, the gap between the receiving portion 22 and the side portion 21a of the shielding plate 21 (the gap between A and B in FIG. 6) is closed with gaskets 8a and 8b. Thereby, the gaskets 8a and 8b can eliminate the hook-shaped portions 14a and 14b.

  Further, even if the hook-shaped portions 14a and 14b are provided, the length of the hook-shaped portions 14a and 14b is shortened and does not come into contact with the second door 2b when the first door 2a is rotated. Thereby, the deformation | transformation etc. of gasket 8a, 8b are lose | eliminated, and deterioration of gasket 8a, 8b can be suppressed.

  Reference numeral 23 denotes a sealing material. The shape of the shielding plate 21 is approximately matched to the shape of the receiving portion 22, but since the rotary partition 5 is a movable body, it is difficult to seal the two completely together. If so, a sealing material 23 having elasticity is provided on the receiving portion 22 side so that it can be absorbed. The sealing material 23 may be provided on the shielding plate 21 side.

  The sealing material 23 is provided in a place near the upper end of the upper end member 16a. Thereby, the inflow of cold air in the gaps A, B, and C in FIG. In addition, it is preferable to block the cool air with a plurality of sealing materials 23 instead of a single sealing material 23. The sealing material 23 is formed of a member that does not become a large resistance when the shielding plate 21 is displaced in the receiving portion 22, for example, silicon rubber.

  Next, referring to FIG. 6, a case where the door is lowered by about 3.0 to 5.0 mm due to a change with time will be described.

  As shown in FIG. 6, the shielding plate 21 of the rotary partition 5 is incorporated at a position having a gap L <b> 2 in the height direction with respect to the receiving portion 22 of the upper receiving seat 10. When the door position is lowered, the rotary partition 5 is also lowered and lowered to the position L3 of the one-dot chain line. As for the shielding plate 21 at the lower end, the one having the gap L4 with the receiving portion 22 is contracted to L5.

  In the present embodiment, the receiving portion 22 is secured to the lower receiving seat 10 assuming a lowering amount L4-L5 of the shielding plate 21 that descends with the door over time. The height dimension of the shielding plate 21 and the height dimension H2 of the rotary partition 5 are set according to this.

  Note that the receiving portion 22 provided on the upper receiving seat 10 has a dimensional relationship such that the gap between the receiving portion 22 and the shielding plate 21 does not increase even when the door position is lowered.

  Further, in FIG. 6, a gap G (shown in FIG. 3) between the end surface of the upper end member 16 a or the lower end member 16 b and the receiving seat 10 (the lower portion may be the inner box 12 without the receiving seat 10). Is covered with gaskets 8a and 8b and flanges 14a and 14b provided on the gaskets 8a and 8b and with a shielding plate 21. Thereby, the cold air flow in the gap G is blocked, but even if there are no hook-like portions 14a and 14b, there is no problem as long as it can be sufficiently closed.

  Further, there are gaps A, B, C between the side portion 21 a of the shielding plate 21 and the receiving portion 22. Therefore, as shown in FIG. 6, the gaskets 8a and 8b cover the gaps A and B, and the gap C is provided with a sealing material 23 to suppress cold air leakage. In the case of the lower receiving part 22, the position of the sealing material 23 is preferably close to the receiving part bottom part 22b. When the sealing member 23 is provided on the receiving portion 22 so as to contact the outer periphery of the back surface of the shielding plate 21, it is necessary to prevent the movement of the rotating partition 5 from being deteriorated. For example, the sealing member 23 is cylindrical, In addition, it is preferable to use a material with good slipperiness such as silicon rubber. The same applies to the upper receiving seat 10.

  In FIG. 6, the flanges 14 a and 14 b are provided in the gaskets 8 a and 8 b so that the gap G is closed by the flanges 14 a and 14 b and the shielding plate 21. This seal is a further improvement. Further, unlike the hook-shaped portions 14a and 14b shown in FIGS. 2 and 3, the hook-shaped portion 14 shown in FIG. 6 has a shorter length (dimension m). In other words, the lengths shown in FIGS. 2 and 3 are longer than the center line, but the hooks 14a and 14b shown in FIG. The reason is that the boundary between the shielding plate 21 and the receiving portion 22, that is, the gaps A and B are closer to the gaskets 8a and 8b, and if the gaps A and B are sufficiently covered with the gaskets 8a and 8b, The shape portions 14a and 14b can also be omitted. Furthermore, since the short hook-shaped portions 14a and 14b do not rub against the door that has been closed without being opened when the first door 2a or the second door 2b is opened and closed, the upper and lower ends are left as in the prior art. Even if the intermediate portion is not deleted, no rubbing sound is generated and the deformation does not occur.

  Next, further description will be given with reference to FIGS. FIG. 7 is an upper cross-sectional view for explaining the movement of the rotating partition during rotation. FIG. 8 is a diagram for explaining a dimensional relationship between the receiving portion and the shielding plate shown in FIG. 9 is a view in which a sealing material is provided in the receiving portion in FIG. 7, FIG. 9A is a front view of the main part of FIG. 3, and FIG. 9B is an XX cross section of FIG. FIG. FIG. 10 is a cross-sectional view corresponding to the YY section of FIG. FIG. 11 is a cross-sectional view corresponding to the YY section of FIG. 9A, and shows a different embodiment from FIG. 10.

  As shown in FIG. 7, along the guide pin 11 provided in the receiving portion 22 of the refrigerator body 1, the guide groove 13 provided in the upper end member 16 a of the rotary partition 5 is guided, so that the rotary partition 5 is Rotate. When the first door 2a and the second door 2b are closed, the rotary partition 5 is in the position of 5 and serves as a receiving surface for the gasket 8b of the second door 2b. When the first door 2a is opened from the closed state, the rotary partition 5 moves along the guide pin 11 and the guide groove 13 moves along the guide pin 11 to the 5 ″ position via the 5 ′ position. Note that when the first door 2a is open (position 2a '), the rotary partition 5 is separated from the gasket 8b of the second door 2b.

  Further, the position of the rotary partition 5 is regulated by a spring 15 shown in FIG. The spring 15 plays a role of maintaining the open state and the closed state of the rotary partition 5. That is, the spring 15 is in the maximum compression state at an intermediate position between the open state and the closed state, and the rotary partition 5 is elastically biased in the opening direction or the closing direction by overcoming this maximum compression state.

  7 and 8, reference numeral 24 denotes a convex portion formed by extrusion molding or the like integrally with the gasket 8b, and corresponds to the collar portion 14 described above.

  Here, the relationship between the shielding plate 21 and the receiving portion 22 in FIG. 7 will be described. If the center line of the gap between the first door 2a and the second door 2b is P, and the shielding plate 21 is provided with a width equivalent to the left and right from the center line P, the rotation trajectory of the shielding plate 21 is as shown in FIG. As shown by the broken line, it becomes a complicated locus K1. When the locus is K1, the concave shape of the receiving portion 22 is complicated, and the shape of the shielding plate 21 is necessarily complicated.

  Therefore, it is necessary to simplify the rotation trajectory of the shielding plate 21 and to simplify the shapes of the shielding plate 21 and the receiving portion 22.

  7 and 8 do not have a configuration in which the shielding plate 21 is distributed to the left and right uniform widths from the center line P, but the intermediate position between the receiving portion 22 and the shielding plate 21 is the first door 2a and the second door 2b. Is positioned closer to the first door 2a than the intermediate position (center line P). In other words, the receiving part 22 and the shielding plate 21 are formed so that the side opposite to the shaft 9 of the rotary partition 5 is short. Accordingly, the rotation locus K2 (the shape of the receiving portion 22) becomes simple as shown in FIG.

  Here, the shielding plate 21 will be further described with reference to FIG. The shielding plate 21 is not located at the left and right equal width from the center line P indicating the center between the first door 2a and the second door 2b, but the dimension L7 opposite to the shaft 9 is set to the shaft 9 side. It is made smaller than the dimension L6. Further, the receiving portion 22 is configured such that the dimension L8 (axis 9 side) is larger than the dimension L9 (opposite side of the axis 9) in accordance with the locus K2 of the shielding plate 21. That is, the shielding plate 21 and the receiving portion 22 are configured such that the first door 2a side where the rotary partition 5 is provided is longer in the width direction than the second door 2b side. Thereby, the locus K2 of the shielding plate 21 is not applied to the guide groove 13 side like the locus K1, and the receiving portion 22 is not applied to the guide groove 13.

  In other words, the shielding plate 21 is formed integrally with the upper end member 16a of the rotary partition 5, and the locus K2 that the shielding plate 21 draws in the receiving portion 22 has a shape that does not cover the guide groove 13 of the upper end member 16a. Left and right widths L6 and L7 from the center line P are determined.

  As a result, the shielding plate 21 can be integrally formed with the upper end member 16a and does not need to be a separate member, so that an inexpensive structure can be achieved.

  In this configuration, it is difficult to cover the gap between the shielding plate 21 and the receiving portion 22 (gap B in FIG. 6; the gap between the shielding plate 21 and the receiving portion 22 on the second door 2b side) only with the gasket 8b. Become. This is because the gap (L9-L7) on the second door 2b side may not be increased by the gasket 8b because of the relationship of L6> L7 and L8> L9. Therefore, as shown in FIG. 8, a convex portion 24 is provided on the second door 2b side.

  On the other hand, the gap (L8-L6) on the first door 2a side (gap A in FIG. 6; the gap between the shielding plate 21 on the first door 2a side and the receiving portion 22) is sufficiently covered only with the gasket 8a. Therefore, the convex portion 24 may not be provided in this portion.

  The reason is as follows. That is, when the shielding plate 21 is based on the center line P, the width (L6) on the first door 2a side is wider than the width (L7) on the second door 2b side. Further, the rotation trajectory K2 of the shielding plate 21 that rotates to rotate the rotary partition 5 is formed in a shape that does not cover the guide groove 13. Thereby, it is because the case where the edge part of the shielding board 21 does not wrap with the gasket 8b by the side of the 2nd door 2b, and a clearance gap is not fully obstruct | occluded is assumed.

  In addition, since the width dimension m (see FIGS. 7 and 8) of the convex portion 24 is a dimension that does not exceed the center line P, it can be formed integrally with the gasket 8b by extrusion molding or the like.

  As described above, the gap L8-L6 (first door 2a side) shown in FIG. 8 is sufficiently covered by the magnetized portion of the gasket 8b, and the gap L9-L7 (second door 2b side) is By covering with the convex part 24, cold air leakage is greatly suppressed.

  Next, in FIGS. 9A and 9B, a gap L <b> 2 may be formed between the tip of the shielding plate 21 and the receiving portion 22. The cold air leaking from the gap L2 is cold air that reaches through the gap D1-D2 (D1: depth dimension of the receiving portion 22, D2: wall thickness of the shielding plate 21) shown in FIG. D1-D2 are formed with a minimum dimensional relationship. However, since the gap cannot be completely eliminated, the sealing material 23 is provided in order to reduce the amount of cool air reaching the gap L2 through the gap D1-D2. This sealing material 23 is also effective for absorbing the error of the locus K2 described with reference to FIG.

  The sealing material 23 is provided in an arc shape on the inner periphery of the receiving seat 10. Moreover, since the sealing material 23 suppresses the amount of cold air that leaks into the gap L2 through the gap D1-D2 from the opening Q formed by the back surface of the shielding plate 21 and the lower end of the receiving seat 10, It is preferable to provide as close to the opening Q as possible. Further, a plurality of them may be provided in order to improve the sealing performance.

  Next, in FIG. 10 and FIG. 11, attachment of the sealing material 23 to the receiving portion 22 will be described.

  In FIG. 10, the sealing material 23 is disposed along the inner periphery of the receiving portion 22 so as to contact the shielding plate 21. By comprising in this way, a structure with high sealing performance is obtained.

  Further, the sealing material 23 shown in FIG. 11 is not disposed along the inner periphery of the receiving portion 22 but is provided at a place where the gap is most easily formed between the receiving portion 22 and the shielding plate 21. Is. With this configuration, even when a stress due to an assembly error or the like is applied to the shielding plate 21, the shielding plate 21 is smoothly displaced, and an efficient seal structure can be obtained.

  Thereby, since the shielding plate 21 can close the gap G regardless of the door position lowering (especially when the shielding plate 21 and the receiving seat 10 are above and below the rotary partition 5), the dew generated by the gap G, It can suppress freezing of condensed water, cold air leakage in the storage room, intrusion of outside air, and the like. Furthermore, the heat insulation effect of the refrigerator main body 1 can be improved.

  Next, FIG. 12 is a figure explaining a different form from FIG. 4, Comprising: It is the principal part longitudinal cross-section of a refrigerator. The shielding plate 21 shown in FIG. 12 has a base portion, which is a fixed end of the shielding plate 21 formed integrally with the upper end member 16a, thinner than the other portion (including the free end), and when the rotating partition 5 rotates, The shielding plate 21 can be displaced to the side opposite to the refrigerator compartment 3, that is, the first door 2a side.

  Thereby, the locus K2 shown in FIG. 8 can be further away from the guide groove 13 and the attachment of the receiving seat 10 to the inner box 12 is facilitated. That is, although the dimension in the depth direction of the locus K2 is provided by recessing the receiving seat 10 toward the heat insulating material, the amount of the recess can be reduced, so that a decrease in heat insulating performance can be suppressed.

  Therefore, by reducing the dimension of the trajectory K2 in the depth direction, the mounting of the receiving seat 10 is facilitated, and the shape change of the inner box 12 can be minimized.

  Further, the fixed end 21 b that is a thin portion of the shielding plate 21 is provided at a lower position away from the receiving portion 22. This is to prevent the fixed end 21b from guiding the cold air to the gaps A, B, and C in FIG. That is, a thin portion is provided on the fixed end 21b at a location that does not contribute to the gaps A, B, and C.

  Since the present invention has the configuration described above, the following effects can be obtained.

  That is, a first door and a second door adjacent to each other, a rotary partition provided rotatably on the first door, a receiving seat provided on the refrigerator main body side for rotating the rotary partition, A refrigerator in which a gap is formed between the rotating partition and the receiving seat, and a concave receiving portion provided on a front edge of the receiving seat, and protruding from the rotating partition toward the receiving seat. A shielding plate that shields the gap and moves in the receiving portion when the first door rotates, the shielding plate having a cross-sectional shape along the receiving portion shape, It provided so that it might become the same plane as the rotating partition front surface. As a result, the shielding plate that closes the gap can close the gap regardless of the conventional lowering of the door position, and can prevent dew, leakage of cold air, intrusion of outside air, and the like.

  Further, the receiving portion has a depth that is in contact with the outer periphery of the shielding plate when the first door is closed, and has a dimension for absorbing the vertical movement of the shielding plate. As a result, the shielding plate can handle even if the door position is lowered, and this shielding mechanism is performed between the seat and the rotary partition, so that it has an inexpensive structure without adding special parts. The gap can be closed.

  Further, at least one of the first door and the second door has a hook-shaped portion provided on the gasket at a position facing the gap, and the first door and the second door are closed. At this time, the gap is closed with the hook-shaped portion and the shielding plate. As a result, the gap is double blocked, so that cold air leakage through the gap is further prevented.

  Further, the shielding plate is an elastic body, and the shielding plate is displaced in the receiving portion when the rotating partition is rotated. Thereby, since the width dimension of a shielding board can be taken wide, the hook-shaped part by the side of a gasket can be eliminated.

  Further, when the gasket is provided on the first door, the gasket is provided on the second door so that the gasket does not come into contact with the second door along the turning locus of the first door. In this case, the gasket does not come into contact with the first door along the trajectory of the second door. Thereby, the deformation of the gasket is eliminated, and deterioration can be suppressed. In addition, a shorter hook-shaped portion can be provided on one side as compared with the conventional case to close the gap.

  Further, the first door and the second door adjacent to each other, a rotating partition provided rotatably on the first door, a receiving seat provided on the refrigerator main body side for rotating the rotating partition, A refrigerator in which a gap is formed between the rotating partition and the receiving seat, and a concave receiving portion provided on a front edge of the receiving seat, and protruding from the rotating partition toward the receiving seat. A shielding plate that shields the gap and moves in the receiving portion when the first door rotates, the shielding plate having a cross-sectional shape along the receiving portion shape, Provided to be on the same plane as the front surface of the rotary partition, the intermediate position of the receiving portion and the shielding plate is closer to the first door than the intermediate position of the first door and the second door To position. Thereby, even if it is a case where a door position falls from the beginning of an assembly, the clearance gap G can be closed appropriately between the overlap part of a receiving part and a shielding board. Further, it is possible to suppress dew condensation, freezing of condensed water, cold air leakage, intrusion of outside air, and the like. Furthermore, since the rotation trajectory of the rotating partition can be reduced and the shape can be simplified, the shape of the receiving portion can be simplified. Further, it does not require a significant design change on the upper end member or the inner box side.

  Further, a gasket is provided on the gap side of the second door, and the gasket has a convex portion facing the gap between the receiving portion and the shielding plate. Thereby, even if it is in the state which cannot cover the clearance gap B (refer FIG. 6) of a receiving part and a shielding board with the gasket 8b, it can cover with a convex-shaped part and can control entrance / exit of gas. In addition, since this convex part is made into the dimension which does not contact a 2nd door at the time of door opening and closing, it becomes a structure which considered the reliability which prevented rubbing.

  A guide pin provided on the seat; and a guide groove provided on the rotating partition that is guided by the guide pin to rotate the rotating partition, and the guide is provided when the rotating partition is rotated. Since the shield plate and the receiving portion are configured so as not to change the rotation trajectory of the groove and the guide pin, the rotation trajectory of the shield plate is not applied to the guide groove. The shielding plate and the receiving portion can be provided without changing the relationship with the groove.

  In addition, the fixed end of the shielding plate is thinner than the free end, and can be displaced toward the first door when the rotating partition is rotated. Thereby, the locus | trajectory in which a shielding board penetrate | invades into the back | inner side of a receiving part is fastened, the attachment to the inner box of a receiving seat is made easy, and the reduction | decrease in heat insulation thickness can be suppressed.

  Moreover, the thin part of the said fixed end of the said shielding board was provided in the downward position from the said receiving part. This prevents the thin portion from guiding cold air to the gaps A, B, and C (see FIG. 6).
