Description

  The present invention relates to a refrigerator provided with a door device that seals and opens an opening of a box.

  In recent years, as refrigerators have become larger, there are provided refrigerators that employ a so-called double door system that opens and closes an opening of a storage room with two doors. In order to keep the interior of the refrigerator airtight with the gaskets provided on the back surfaces of both doors, the conventional refrigerator with double doors has to form a surface on which the gasket located on the non-pivot side of the door comes into contact. The closing material which partitions the opening part of a heat insulation box was attached (for example, refer patent document 1).

  7 to 10 show a conventional refrigerator door device described in Patent Document 1. FIG. FIG. 7 is a perspective view of a conventional refrigerator. FIG. 8 is a front view of a conventional refrigerator. FIG. 9 is a plan sectional view of an opening of a conventional refrigerator. FIG. 10 is a perspective view of a conventional refrigerator door.

  7 to 10, reference numeral 1 denotes a refrigerator, which is located forward from an outer box 2 made of steel plate and an inner box 3 formed of synthetic resin, and a foam heat insulating material (not shown) filled between the boxes 2 and 3. An opened heat insulating box 4 is configured, and the opening 5 is formed by two double doors 7 and 8 pivotally supported by upper and lower hinges 6 on the left and right edges of the opening 5 of the heat insulating box 4. It can be opened and closed freely.

  Guide members 9 are provided opposite to each other on the top and bottom of the edge of the opening 5 of the heat insulating box in the portions located on the non-pivot side of the doors 7 and 8. A guide groove 10 is formed in the guide member 9.

  A pair of left and right vertical walls 13, 14 are formed on the door inner plates 11, 12, respectively, and a gasket 19 with a built-in magnet is attached to the grooves 17, 18 at the ends of the frame members 15, 16. Close contact with the vertical walls 13 and 14 on the non-pivot side. The gasket 19 is magnetized on the front edge of the outer box 2 of the opening 5 of the heat insulating box 4 when the doors 7 and 8 are closed, thereby sealing the inside 21.

  Further, a partition 22 having a substantially rectangular cross section is attached to the outside of the vertical wall 13 inside the gasket 19 positioned on the non-pivot side of the back surface of the door 7. Reference numeral 23 denotes a hinge plate, which is fixed at two places on the outer surface of the vertical wall 13 by screws 24 to the reinforcing plate 23a on the heat insulating material side, and the partition 22 is freely rotatable on a rotation shaft 25 of the hinge plate 23. It is supported by.

  Further, projections 26 are formed as engaging portions on the upper and lower ends of the partition 22 so as to protrude in the vertical direction. The hinge plate 23 is inserted into the partition 22 through two notches 27 formed on the rear edge of the partition 22 on the door 7 side, and a rotating shaft 25 is positioned there. A spring member 28 made of a coil spring is inserted through one end, and one end is engaged with the hinge plate 23 and the other end is engaged with a claw 29 in the partition 22 spaced apart from the rotating shaft 25, respectively. The partition 22 is always rotated clockwise as indicated by an arrow in FIG.

  About the conventional door apparatus comprised as mentioned above, the operation | movement is demonstrated below.

  First, the partition 22 is held in a state in which the door 7 is in contact with the screw 24 along the outer side surface of the vertical wall 13 of the door inner plate 11 by the restoring force of the spring member 28 with the restoring force of the spring member 28 shown in FIG. Has been. Even if the user's hand accidentally hits the partition 22 and is rotated counterclockwise in FIG. 9 in this initial state, the spring member 28 can return to the initial state.

  Next, when the door 7 is closed, the protrusion 26 of the partition 22 enters the guide groove 10 and slides along the curved surface in the guide groove 10. The center is rotated counterclockwise against the spring member 28, and the protrusion 26 enters the inner part of the guide groove 10. On the contrary, when the door 7 is opened, the projection 26 slides along the curved surface in the guide groove 10 and is rotated clockwise by the restoring force of the spring member 28, and eventually returns to the initial state.

Thus, it is necessary to provide a partition fixed to the opening 5 side between the doors 7 and 8 by rotating the partition 22 in accordance with the opening and closing of the door 7 to securely seal the gasket 19. Since there is no, the opening of the opening 5 can be used widely.
