DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer type door structure for a refrigerator.

[0002]

2. Description of the Related Art In recent years, it has become mainstream that even small-sized refrigerators have a drawer-type door.

A conventional refrigerator door structure is disclosed in Japanese Utility Model Publication No. 60-27350.

Hereinafter, a drawer type door structure of the above-mentioned conventional refrigerator will be described with reference to the drawings. 15 is a front perspective view of a refrigerator provided with a conventional drawer-type door, FIG. 16 is a central sectional view of a conventional drawer-type door, FIG. 17 is a detailed view showing part A of FIG. 16, and FIG. FIG. 17 is a sectional view taken along the line BB of FIG. In FIG. 15, reference numeral 1 denotes a refrigerator body (hereinafter, referred to as a refrigerator) provided with a drawer-type door (hereinafter, referred to as a door) 2 for closing a front opening in the refrigerator. The door 2 is fitted with a door frame 5 in which the door frame reinforcing plate 4 is inserted on the four sides of the door outer panel 3, and the door back surface reinforcing plate 7 is fixed to the left and right sides of the door frame back surface 6 with screws 8 (not shown). Then, each part is fixed by filling the foamed polyurethane heat insulating material 9 therein. A handle 10 is fixed to a front surface of the door 2 with screws 11 (not shown) and is covered with a handle cover 12. Reference numeral 13 denotes a frame that supports and fixes the container 14 so as not to abut on the bottom 15 of the box in the refrigerator. The end 16 is fixed to the door back reinforcing plate 7 by a screw 17. Reference numeral 18 denotes a frame roller pivotally attached to the rear portion of the frame 13, which rides on a rail 20 provided on the refrigerator inner box side wall 19, and the lower side edge 21 of the frame 13 is connected to the refrigerator inner box side wall 19. Roller 22 protruding from the front portion of the
I'm on Reference numeral 23 denotes a sheet-metal-molded rail reinforcing plate for fixing the rail 20 and the front roller 22 to the refrigerator inner box side wall 19, and 24 fills the foamed polyurethane insulation material 9 into the refrigerator outer box outer wall and the refrigerator inner box side wall 19. By doing so, it is fixed.
