Embodiment 1

[0022] figure 1 It is a perspective view of a refrigerator to which the present invention is applied. This refrigerator is composed of a heat insulating box 2 provided with a heat insulating material between a steel plate outer box 1 opened at the front and an inner box made of a resin material not shown in the figure. Separated into multiple chambers. The front openings of the partitioned chambers are closed by swing-type doors 3 , 4 , 5 , 6 , and 7 so that they can be freely opened and closed. In this embodiment, 3 and 4 are refrigerator compartment doors, 5 is an ice compartment door, 6 is a freezer compartment door, and 7 is a vegetable compartment door. 8 is the evaporating dish cover that collects the water that produces when defrosting in the room. The doors of all the chambers show a door structure in which a handle of the same cross-sectional shape for opening and closing is provided in the center and opened to both sides. Therefore, the plurality of doors arrange...

Abstract

The present invention provides a refrigerator door capable of ensuring design property and strength and preventing dew condensation in a hand grip part with a minimized number of part items. The refrigerator comprises the refrigerator door covering an opening of a storage chamber, the door being opened and closed, thereby storing a storage matter in the storage chamber; a door outer plate made of a steel plate, which is arranged on the outer surface of the refrigerator door, and has a heat insulating material arranged in a space with a door inner plate combined to the inside thereof; a handle fixed to one side end of the door outer plate, and having a hand grip part formed of a recessed part for inserting a hand from the outside and a protruding part to be gripped at the time of opening and closing the refrigerator door; and a door cap fitted to the upper edges and lower edges of both the handle and the door outer plates to integrally form the refrigerator door. The handle is formed of a metal extrusion molded product of aluminum or the like.

Description

technical field [0001] The present invention relates to the structure of the refrigerator and the manufacturing method of the door. Background technique [0002] The door of present refrigerator is that the handle part of the resin material that injection molding is made is fixed on the door part with fasteners such as screws. Therefore, there are problems in that the number of parts is large and the mold is complicated. As a current refrigerator door manufacturing technology to solve this problem, a refrigerator door made of a handle body made of synthetic resin material by extrusion molding and a handle cover attached to the end of the handle is known. (For example, refer to Patent Document 1). In addition, there is a door that is provided with a handle shape by bending the door outer panel made of steel plate. (For example, refer to Patent Document 2). [0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 4-313674 (page 5, figure 1 ); [0004] [Pat...
