Description

  The present invention relates to a refrigerator, and more particularly to a drawer door.

  In recent years, it has become common for refrigerators to use rollers as members that support the frame on which the food storage case is placed from below (see, for example, Patent Document 1).

  Hereinafter, the conventional refrigerator will be described with reference to the drawings.

  3 and 4 are sectional views showing a conventional drawer door device of the refrigerator described in Patent Document 1. FIG.

  In the figure, 1 is a refrigerator main body, 2 is a heat insulating material filled between the inner box 3 and the outer box 4, and 5 is a rail portion fixed to a pair of both side walls of the inner box 3, and the rear part of the frame 6. The moving roller 7 provided on the slides. Reference numeral 8 denotes a main body side fixed roller embedded in both ends of the lower middle partition wall 9, which is attached to the lower middle partition wall 9 via a shaft 8a, and the first flange portion 6a of the frame 6 slides. Reference numeral 10 denotes a case 10 placed on the inner side of the second flange portion 6b of the left and right frames 6 and on the first flange portion. The frame 6 is substantially L-shaped so as to cover the lower corners on both sides of the case 10. positioned.

  Reference numeral 11 denotes a roller storage box which is a fixed roller storage portion embedded in both ends of the lower inner partition wall 9. The main body side fixed roller 8 is a roller via a shaft 8 a engaged with a claw 11 a of the roller storage box 11. It is attached to the storage box 11.

Reference numeral 11c denotes an L-shaped rib provided on the front horizontal portion of the roller box 11, and suppresses left and right blurring when the drawer door 16 is pulled out by contacting the frame 6.

  However, in the above conventional refrigerator, the combined dimensional accuracy of the roller attached to the lower inner partition wall via the roller storage box and the rail deteriorates, and the position of the door varies vertically when the drawer door is pulled out. Had problems. In addition, there is a problem that the number of parts increases and costs increase.

  The present invention solves the above-described conventional problems, and an object thereof is to provide an inexpensive refrigerator in which the drawer doors do not vary up and down.

  In order to solve the above-described conventional problems, the refrigerator of the present invention includes a main body formed of a heat-insulating material filled and foamed in a space surrounded by an outer box and an inner box, and a storage chamber for the main body. A partition wall and a drawer door to which a frame for placing a food storage case is attached are provided in the storage chamber, and the middle partition wall is filled with a heat insulating material in a space surrounded by an upper partition member and a lower partition member. The first projection shape for supporting the frame from below is formed integrally with the partition member.

  Thus, the roller and the roller storage box are fixed by the heat insulating material filled in the main body and the partition wall and the dimensional accuracy is increased, and the first and second protrusions are integrally formed from the partition wall, thereby providing the roller and the roller storage box. The number of parts can be reduced.

  The refrigerator of the present invention can provide an inexpensive refrigerator in which there is no vertical variation in the drawn out door.

  The invention according to claim 1 is a main body formed of a heat insulating material filled and foamed in a space surrounded by an outer box and an inner box, a partition wall that defines a storage chamber of the main body, and a food storage case The storage chamber is provided with a drawer door to which a frame for mounting the frame is mounted, and the inner partition wall is filled and foamed with a heat insulating material in a space surrounded by the upper partition member and the lower partition member, and supports the frame from below. The first protrusion shape is integrally formed with the partition member, and is fixed by a heat insulating material filled in the main body and the partition wall, so that the dimensional accuracy is increased, and the first protrusion is integrally molded from the partition wall. By providing the protrusions, the roller and the roller storage box can be eliminated, the number of parts can be reduced, and an inexpensive refrigerator can be provided in which the drawer door does not vary vertically.

  According to a second aspect of the present invention, in the first aspect of the present invention, the second protrusion shape for guiding the side surface of the frame formed on the partition member is formed independently of the first protrusion shape. When a large load is applied to the storage case, the deformation is only the first protrusion and the deformation is not transmitted to the second protrusion, so that a correct guide is provided and the drawer door does not shake from side to side. be able to.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a partial longitudinal sectional view of a drawer door device for a refrigerator according to Embodiment 1 of the present invention, and FIG. 2 is a partial side sectional view of the drawer door device for a refrigerator according to Embodiment 1 of the present invention.

  In FIG. 1 to FIG. 2, 1 is a refrigerator body, 2 is a heat insulating material filled between the inner box 3 and the outer box 4, and 5 is a rail portion fixed to a pair of both side walls of the inner box 3, A moving roller 7 provided at the rear of the frame 6 slides. The lower middle partition wall 9 is composed of the heat insulating material 2 filled between the upper partition member 9a and the lower partition member 9b on the storage chamber 12 side, and is integrally configured with the heat insulating material 2 together with the main body. Reference numeral 13 denotes a first protrusion formed integrally from the upper partition member 9a on the storage chamber 12 side, and is disposed near both ends of the lower middle partition wall 9. The first flange portion 6a of the frame 6 slides. Move. Reference numeral 10 denotes a case placed on the inner side of the second flange portion 6b of the left and right frames 6 and on the first flange portion. The frame 6 is positioned in a substantially L shape so as to cover the lower corners on both sides of the case 10. is doing.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the refrigerator main body 1 and the lower partition 9 are integrally foamed with the heat insulating material 2, there is no rattling, and the lower middle partition wall 9 is also integrally foamed with the heat insulating material 2, so there is no deflection. Therefore, since the dimensional relationship between the rail portion 5 and the first protrusion shape does not vary, it is possible to provide a refrigerator in which the door that is pulled out does not vary up and down. Moreover, since the 1st protrusion shape 13 is integrally shape | molded from the upper partition member 9a by the side of the storage chamber 12, since it can be comprised by one part and the number of parts can be reduced, there exists an effect that an inexpensive refrigerator can be provided. .

  Reference numeral 14 denotes a second protrusion shape integrally formed from the upper partition member 9a on the storage chamber 12 side, which is disposed at both ends of the lower middle partition wall 9, and is independent of the first protrusion shape 13. Because when the large load is applied to the storage case, the deformation is only the first protrusion shape, and the deformation is not transmitted to the second protrusion shape. Can be provided.

  As described above, the refrigerator according to the present invention can provide an inexpensive refrigerator that does not vary in the vertical direction of the drawer door, and thus can be applied to objects other than a cooling device having a drawer door such as kitchen furniture and furniture.
