Abstract

PROBLEM TO BE SOLVED: To simplify a sliding roller attaching structure and improve the pulling-out operability of the structure by reducing the load applied to each sliding roller, by evenly receiving the load of foodstuffs housed in an upper case in a pulling-out door at multiple points by means of two sliding rollers and a flange section attached to the upper case. SOLUTION: The main body of a refrigerator is provided with an upper case 8, a lower case 9, and a pulling-out door section partitioned from the outside by a pulling-out door 5. First sliding rollers 16 attached to the front side faces of the upper case 8 are slid on flange sections formed in the upper sections of both side faces of the lower case 9, and second sliding rollers 18 attached to the rear-side upper sections of the upper case 9 are slid on first projecting rail 20 integrally formed with both side walls of the inner box 2 of the refrigerator. In addition, flange sections 8b integrally formed with both side walls of the inner box 2 are slid on second projecting rail 21. Therefore, the load of foodstuffs housed in the upper case 8 can be received evenly at multiple points.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly to a drawer mechanism for an upper case in a drawer door having two upper and lower cases.

[0002]

2. Description of the Related Art FIG. 9 is a front view showing an upper case drawer structure in a drawer door of a conventional refrigerator in two upper and lower cases, and FIGS. 10 and 11 are longitudinal sectional views of a drawer door portion of the conventional refrigerator. 12 and 13 are cross-sectional views of the upper case sliding roller portion of the drawer door portion of the conventional refrigerator. In the figure,
1 is a refrigerator body, 2 is a refrigerator inner box, 3 is a pair of plastic molded rails attached to both side walls of the inner box 2,
4 is a roller attached to the rail 3, 5 is a drawer door, 6 is an inner plate of the drawer door 5, 6a is a recess for a cool air circulation path for cooling the drawer door, and 7 is a drawer door. 8 and 9 are food storage cases arranged in upper and lower tiers in a compartment partitioned by the drawer door 5, 8 is an upper case, 9 is a lower case, and 8a is for pulling out an upper case. It is a handle.

[0003] Reference numeral 10 denotes a frame mounted inside the left and right flanges at the upper side of the upper case 8, reference numeral 11 denotes a sliding roller mounted at a lower rear portion of the frame 10, reference numeral 12 denotes an attachment for fixing the sliding roller 11, 13 is a sliding roller attached to the frame 7 of the drawer door 5, 14 is a pair of guide rails for the rollers 13 attached to both side walls of the inner box 2, and 15 is a roller attached to the rail 14.

[0004] Since the case drawer mechanism in the drawer door of the conventional refrigerator is configured as described above, the drawer door 5 is pulled out and the upper case 8 is housed in the upper case with the upper case 8 pulled out toward the user.

[0027]

The refrigerator according to the present invention has an upper case and a lower case, and is provided at a drawer-type drawer door portion separated from the outside by a drawer door, and at a lower portion on the side of the upper case at the side of the lower case. A first sliding roller that slides on a lower case flange portion provided on an upper side surface of the case, and a first rail protrusion provided on a main body and provided on a rear upper side surface of the upper case. By providing the second sliding roller and the upper case flange portion provided on the upper side of the upper case and provided on the main body, the load of the food stored in the upper case in the drawer door can be reduced. It is possible to receive evenly at multiple points of the first sliding roller, the second sliding roller and the upper case flange attached to the upper case, and it takes one sliding roller as compared with the conventional one. Load is 1 / It is reduced to below. Therefore, the mounting structure of the sliding roller can be simplified.

Further, the handle portion having the opening of the upper case is configured so as to be located in the concave portion provided inside the drawer door when the drawer door is closed, so that the storage space for the upper case is provided. Can be increased.

Further, the upper case can be easily removed by using the upper case flange as a handle for removing the upper case.

The handle of the upper case has an opening, and is configured to be located in a recess provided inside the drawer door in a state where the drawer door is closed, so that the recess matches the opening. Since the space portion is penetrated, the handle portion can be located at a position that is very easy to use with normal usability.

The upper case is provided on the upper side surface of the case,
Since the upper case flange portion that slides on the second rail protrusion provided on the main body is provided, the mounting structure of the sliding roller can be simplified.

[0032] Further, the door is provided with a protruding portion protruding downward in front of the ceiling portion (main body side) of the storage room opened and closed by the drawer door, and another protruding portion protruding upward behind the flange of the upper case. Since they are arranged so as to face each other in the opening and closing direction, the handle portion can be located at a position that is very easy to use with normal usability.

In a state where the drawer door is closed, a first sliding roller provided on the lower front side of the upper case is disposed in front of the lower case flange provided on the upper side surface of the lower case. The upper case can be pulled out together with the lower case because it is configured to match the recessed portion.

Further, the upper case has a side wall provided with a gap outside the lower case flange provided on the upper side surface of the lower case and a first sliding roller provided on the front lower side of the side surface of the upper case. The door can be smoothly opened and closed.

In addition, a U-shaped slit hole is provided on the outer periphery of the base of the downwardly protruding convex portion in front of the ceiling (main body side) of the storage room opened and closed by the drawer door, and the convex portion has a spring function. Therefore, even if the upper case-side protrusion is located ahead of the ceiling-side protrusion, such as when the upper case is removed and then set again, the ceiling-side protrusion moves upward with a little resistance. The case can be pushed in.
