DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, this type of refrigerator is disclosed in, for example, JP-A-6-159916. Hereinafter, a conventional refrigerator will be described with reference to the drawings.

FIG. 11 is an external perspective view of a conventional refrigerator. FIG. 12 is a sectional view of a main part of a conventional refrigerator.

[0004] 1 is a refrigerator main body, 2 is a freezer compartment door provided on the front surface of the main body 1, and 3 is a refrigerator compartment door. 4 and 5 are freezer doors 2
In addition, an outer plate of each door made of a steel plate member constituting a front portion of the refrigerator compartment door 3 has a central portion curved forward to form a round shape. 6 is a freezer compartment door 2 facing the door outer plate 4.
7 is a gasket mounted inside the freezer compartment door 2, and 8 is a gasket attached to the inside of the freezer compartment door 2.
Is a door sash for fitting the gasket 7, and 9
Is a door cap attached to the upper and lower ends of the door outer plate 4.

[0005] Reference numeral 10 denotes a handle formed around a notch in the front plate of the door outer plate 4, and a body 1 formed of resin.
1, a base 12 and a trim 13 are formed, and a bag-like portion 14 is formed as a handle for opening and closing the door.
Reference numeral 15 denotes a foamed heat insulating material such as a polyurethane resin.

Next, the operation of the above configuration will be described.

The base 12 is curved concavely so as to form a bag-like portion 14 of the handle 10, and its surface is provided with a scratch having high hardness so as to match a film steel plate having a film adhered to the surface of the door outer plate 4. Thermal transfer of less hot stamp foil.

An ABS engaged with the lower end of the door outer plate 4
The door cap 9 made of resin is formed with a cutout portion that is curved so as to form the bag-like portion 14 of the handle 10.

The refrigerating compartment door 3 is provided with a handle 10 having a reciprocal design which is symmetrical with respect to the freezing compartment door 2 in the up-down direction, so that the refrigerating compartment door 2 and the refrigerating compartment door 3 communicate with each other. Since it is formed, it has a convenient shape for opening and closing the door.

[0010] In addition to having a handle with excellent appearance and design that is less likely to protrude from the door outer plate 4, the position of the bag-like portion 14 can be freely provided. It is described that the strength of the handle 10 can be improved because the cover foam insulation material 15 is configured to be filled and adhered to the back surface of the door outer panel 4.

[0011]

However, in the above-described conventional construction, the door outer plate 4 is a steel plate member, and can be formed into a three-dimensional curved surface in a round form.
Depending on the shape, the mold cost is very high, which causes an increase in cost.

Further, since the door outer plate 4 is made of a steel plate, it is necessary to configure the handle 10 with the body 11, the base 12, and the trim 13 in order to realize a handle 10 having an excellent design. Also caused an increase.

Further, the handle 10 is entirely made of a resin part, which may cause a loss of quality and quality in a refrigerator that emphasizes such a design.

Further, since the door outer plate 4 is made of a steel plate, it is very difficult to form a positioning groove for mounting a name plate on the door outer plate 4, and it is necessary to attach another part to the door outer plate 4 for positioning. This is inferior in design, increases the number of mounting steps, and increases the cost.

The present invention solves the above-mentioned conventional problems, and a first object of the present invention is to economically realize a refrigerator door which is easy to use and excellent in design including a handle.

A second object of the present invention is to provide a high-quality refrigerator door with a high-grade handle.

[0017]

In order to achieve this object, the present invention comprises a handle for opening and closing a door, and
The dollar is formed with a substantially circular handle portion and the handle portion.
With an approximately L-shaped mounting part, made of resin and convex
Positioning the mounting portion on a door surface having a curved surface
Groove formed integrally from the door surface to the door side surface
And a step formed in the concave groove, wherein the hand
Do not protrude from the door surface in the groove
So that the handle is fixed
A decorative plate covering a surface portion is fixed on the step portion
It is.

Thus, the design is economical and easy to use.
Door with excellent handle strength
it can.
