It is a principal part top view explaining the relationship between a door and a 2nd door with the state in a seal | sticker pillar drive device.

  In FIG. 7, the storage of the refrigerator 1 is opened and closed by a pair of double-open doors, and the first door and the second door forming the pair of doors are axially supported on the refrigerator 1 by hinges on the outside. Yes.

  On the open end side of the first door 2 is attached a seal column 4 that rotates so as to advance and retreat toward the second door 3 side. The operation of the seal column 4 is in the inner rotation position, that is, the retracted position where it does not protrude from the open end of the first door 2 in the state shown in FIG. The retracted position is maintained until the first door 2 is closed and the second door 3 is opened as shown in FIG. This is because the sealing column 4 is urged by the urging means (not shown) toward the retracted position.

  Next, when the second door 3 is closed, the seal column driving device (details will be described later) arranged on the upper inner surface of the storage in conjunction with this closing operation resists the force that biases the seal column 4 to the retracted position. Then, as shown in FIG. 7C, the seal column 4 is rotated to the forward position protruding toward the second door 3 side, and the first door 2 and the second door 3 are reliably sealed.

  Therefore, when the interlocking lever 6 is in the state shown in FIG. 9A, the guide body 18 is orthogonal to the interlocking lever 6 as shown in FIG. 9B, and the guide body 18 is shown in FIG. The seal column 4 attached to the lower portion is stored in the storage portion 17 of the first door at the retracted position. When the interlocking lever 6 is in the state shown in FIG. 9C, the guide body 18 is parallel to the interlocking lever 6 as shown in FIG. Rotates to a forward position protruding toward the second door 3 side. Note that the circles indicated by dotted lines in FIGS. 9B and 9D are fulcrums around which the seal column 4 rotates.

  As described above, in the state shown in FIGS. 7A, 7 </ b> B, and 7 </ b> D, the protrusion 16 protruding from the second door 3 is in a state of not pressing the action portion 11. In the state shown in (a) and (b), the seal column 4 is in the retracted position of the first door 2, and in the state shown in (c) of FIG. 9 presses the action portion 11 to be in the state shown in FIGS. 9C and 9D, and the seal column 4 rotates to the forward position protruding toward the second door 3 side. 7E, even if the protrusion 16 of the second door 3 pushes the action portion 11, the first door 2 is opened and the guide body 18 at the upper end of the seal column 4 of the first door 2 is Since the guide body 18 is not engaged with the drive pin 13 of the seal column driving device 5 and is urged by urging means (not shown), the guide body 18 is in the state shown in FIG. The column 4 is in the retracted position of the first door 2.

  Next, the case where the 1st door 2 is closed by (a), (b), (c), (d) of Drawing 11, and the 2nd door 3 is in various states is shown. In FIG. 11A, both the first door 2 and the second door 3 are closed, and the guide body 18 and therefore the seal column with the guide body 18 attached to the upper end is parallel to the opening surface of the refrigerator and can be sealed. . FIG. 11B shows a case where the second door 3 is slightly opened, and FIG. 11C shows a case where the second door 3 is further opened. At this time, it can be seen that the guide body 18 and therefore the sealing column rotate along the door back body, that is, to the retracted position of the first door 2. Further, when the second door 3 is closed as shown by an arrow in FIG. 11 (d), the guide body 18 and thus the seal column rotate clockwise and move in the direction shown in FIG. 11 (a). I understand that.

As described above, the interlocking lever 6 is rotated by the protrusion 16 of the second door 3, and the drive pin 13 moves in the pin sliding slot 12 and the pin guide groove 9 in response to the rotation of the interlocking lever 6. The guide body 18 attached to the upper end of the column can be rotated clockwise or counterclockwise so that the seal column 4 can be rotated smoothly.

FIG. 5 is a plan view of another interlocking lever of the seal column driving device of the refrigerator of the same embodiment, and FIG. 6 is an enlarged view of the operating body mounted on the second door of the refrigerator of the same embodiment.

  A spacer 20 having a hole in the center and formed into a disk shape with a resin material is located between the pin sliding long hole 12a of the interlocking lever 6a and the pin guide groove 9 of the lower case member 7b, and is driven to the center hole. A pin 13a is inserted and pivotally supported. The diameter of the spacer 20 is set to be larger than the groove width of the pin sliding long hole 12a and the pin guide groove 9 through which the drive pin 13a moves, and the thickness of the spacer 20 is the upper case member within the seal column driving device 5a. The clearance between the interlocking lever 6a and the inner surface of the lower case member 7b in which the pin guide groove 9 is formed when the upper surface of 7a is abutted is substantially the same.

  A plurality of ribs 23 are provided on the upper surface of the upper case member 7a of the seal column driving device 5a in contact with the upper flange 14 of the driving pin 13a along the operation direction of the driving pin 13a.

  Further, buffer members 24 are provided at both ends of the pin sliding long hole 12a so that the drive pin 13a does not directly collide with the wall surface inside the arc of the pin sliding long hole 12a formed in the interlocking lever 6a. The buffer member 24 uses an elastic member such as a spring or rubber.

  Further, a protrusion cover 21 made of a flexible material is attached to the protrusion pin 22 of the operating body 16a attached to the second door 3 from above.

  The drive pin 13a may be resin-molded, but may be formed of a metal material having a specific gravity greater than that of the resin.

  With the above configuration, the drive pin 13a having the flange 14 is inserted into the pin sliding long hole 12a, and the drive pin 13a is further inserted into the cam groove 19 above the seal column 4 through the pin guide groove 9 formed in the seal column drive device 5a. The seal column 4 is inserted to rotate, and the spacer 20 is pivotally supported on the drive pin 13a between the interlocking lever 6a having the pin sliding long hole 12a and the surface having the pin guide groove 9 formed thereon. Therefore, the clearance around the drive pin 13a can be set to a minimum while improving the usability by preventing the seal column 4 from protruding toward the second door 3 when the second door 3 is opened and closed. By suppressing the rattling during the operation of the drive pin 13a, the collision noise between the components in the seal column driving device is reduced, and the quality when the refrigerator door is opened and closed can be improved.

  The diameter of the spacer 20 is set to be larger than the groove width of the pin sliding long hole 12a and the pin guide groove 9 through which the drive pin 13a moves, and the thickness of the spacer 20 is such that the drive pin 13a is placed in the upper case member within the seal column driving device 5a.

It is possible to reduce the impact force that hits. Thereby, the centrifugal force is reduced and the sound generated at the time of the collision by the drive pin 13a can be further reduced, and the quality of the refrigerator can be improved.

  In addition, since a plurality of ribs 23 are provided along the operation direction of the drive pin 13a on the upper surface of the upper case member 7a of the seal column drive device 5a in contact with the upper flange 14 of the drive pin 13a, the vertical direction of the drive pin 13a is increased. It becomes possible to restrict play. Thereby, the sound which generate | occur | produces in the case of a collision can be reduced and the quality of a refrigerator can be improved. Further, the contact surface between the upper flange 14 surface of the drive pin 13a and the rib 23 is reduced, and the drive pin 13a can move smoothly. Further, sliding noise can be reduced by reducing the contact surface.

  Further, since the protrusion cover 21 made of a flexible material is attached to the protrusion pin 22 of the operating body 16a attached to the second door 3 from above, the flexible material of the operating body 16a is closed when the second door 3 is closed. The protrusion cover 21 can reduce the impact with the action portion 11 formed on the interlocking lever 6a, reduce the vibration transmitted from the interlocking lever 6a to the drive pin 13a, and reduce the impact between the interlocking lever 6a and the drive pin 13a.

  The drive pin 13a may be resin-molded. However, when a metal pin having a specific gravity greater than that of the resin is used, the drive pin 13a eliminates play in the vertical direction due to its own weight, and the interlocking lever 6a rotates. Thus, by moving in parallel along the pin sliding long hole 12a, it is possible to reduce the sound generated at the time of a collision by the drive pin 13a and to improve the quality of the refrigerator.

  Further, in place of the buffer members 24 provided at both ends of the pin sliding long hole 12a formed on the interlocking lever 6a, as shown in FIG. Alternatively, a flexible member 25 may be provided. In this case, it is possible to reduce the sound including the sliding sound when the drive pin 13a and the pin sliding long hole 12a slide, and to further improve the quality of the refrigerator.

  As described above, the refrigerator according to the present invention can reduce the collision noise of components when the door is opened and closed, and can improve the original quality of the product, so that it can be applied to applications such as a refrigeration apparatus having a double door. .
