Description

TECHNICAL FIELD The present invention relates to a door structure for a refrigerator, a freezer or the like.

2. Description of the Related Art A conventional refrigerator door structure will be described with reference to FIGS. 3, 4, and 5.

Reference numeral 1 denotes a refrigerator body, which includes an outer box 2, an inner box 3 and a door 4.
The door 4 is formed by bending a side 5 formed by profile extrusion to form four sides, and a seam portion is formed as a portion to form a door frame. The flat panel 6 is inserted before the side 5 is bent, and the heat insulating material 7, the door packing 8, and the door inner plate 9 constitute the door 4.

The handle 10 for opening and closing the door is tightened and fixed to the door 4 with a screw 11, and a cap 12 is fitted over the entire handle so that the screw 11 cannot be seen from the outside, thereby forming a handle portion.

Problems to be Solved by the Invention However, in the conventional structure, since the side 5 forming the door frame is bent, the seam is cut by 45 °, and the burr on the cut surface and the seam on the vertical and horizontal sides are displaced. There are some cases in which a person using a refrigerator is injured due to a step due to the step or burr, and at the time of manufacturing the refrigerator, especially this joint part is finished with great care. ,
It was time-consuming and expensive.

In addition, since the handle part is on the business trip from the panel side, the number of packing people is increased and the transportation efficiency is poor.

In order to eliminate the conventional problems, the present invention has a structure in which no burr or step is formed in the seam, so that no injury is required or finishing is required, and the handle is integrally formed with the door frame. As a result, the number of packaging workers can be reduced and the transportation efficiency can be improved.

Means for Solving the Problems In order to achieve the above object, the present invention forms a door frame by inserting and fitting a side formed by profile extrusion into a side formed by injection molding having a recess for opening and closing the door. The structure.

Therefore, the present invention inserts and fits the door frame into the side formed by profile extrusion and the side formed by injection molding in which the end of this side is pushed in and the recess for opening and closing the door is integrally formed. By configuring, the end of the profile extrusion molding is covered with the side of the injection molding, and the conventional problem is solved without the end being exposed on the surface.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2, but the same components as those of the prior art will be designated by the same reference numerals.
Detailed description thereof will be omitted.

Reference numeral 13 denotes a recess for opening and closing the door, which is integrally provided on an upper side 14 formed by injection molding. Denoted at 15 is a side formed by profile extrusion molding, which forms the left and right sides and the lower side. The side 15 is inserted and fitted into the side 14 to form a frame 16. Further, the panel 6 is inserted into the side 15, and the upper side 14 is further inserted so that the sides 14 and 15 and the panel 6 are fitted. The door 17 is constructed by attaching the heat insulating material 7, the door inner plate 9, and the door packing 8 to the frame 16.

That is, the handle portion for opening and closing the door is replaced by the recessed portion 13 provided on the side 14, so that the handle portion does not travel than the door 17 and the number of packing can be reduced and the transportation efficiency can be improved.

Further, by inserting and fitting the side 15 of profile extrusion molding into the side 14 of injection molding, the end portion 18 of the side 15 is covered with the side 14, so that injury due to burrs or the like of the joint portion can be prevented.

EFFECTS OF THE INVENTION As is clear from the above description, the present invention is formed by injection molding on the frame forming the door structure, and the side formed by the modified extrusion molding is inserted and fitted into the side integrally provided with the recess for opening and closing the door. As a result, the end portion of the profile extrusion molding is hidden, so that injury due to this end portion can be prevented.

It also has the excellent effects of reducing the packaging talent and improving the transportation efficiency.
