DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door having improved design of a refrigerator.

[0002]

2. Description of the Related Art In recent years, the number of colors of a door of a refrigerator has been increased in order to improve the design, and the color has been given a gloss.
And there is a tendency that the gloss is deep and the design property is further improved.

Conventionally, as a door of this kind of refrigerator, NR-F sold by Matsushita Reiki Co., Ltd. in February 1991 has been used.
There is a door for a 46K1 refrigerator. Hereinafter, the conventional refrigerator door will be described with reference to the drawings.

FIG. 8 is a perspective view of a door, and FIG. 9 is a sectional view of the door. In the figure, reference numeral 1 denotes an iron plate 1a and a transparent layer 1
0.1mm thick decorative film 1 consisting of b and printed layer 1c
d is an outer panel attached with an adhesive 1e. 2 is the outer panel 1
The inner plate is arranged to face the inner plate. Reference numeral 3 denotes a frame having a substantially U-shaped outer plate insertion portion 3a to be inserted into the entire periphery of the outer plate 1. Reference numeral 4 denotes a heat insulating material that is foam-filled in a space formed by the outer plate 1, the inner plate 2, and the frame 3. Reference numeral 5 denotes a door reinforcing member inserted on the heat insulating material 4 side of the frame 3.

[0005]

However, in the above-described structure, the decorative film is used to make the surface glossy.
Since the decorative film cannot be made thick, it is not possible to make the gloss deep.

[0006] When attaching a decorative film to an iron plate,
The surface of the outer plate is uneven and does not become flat due to trapping bubbles and dust, opening and closing irregularities of the adhesive, and opening and closing irregularities on the surface of the iron plate.

When the door is exposed to cold heat, the adhesive is peeled off and lifted up due to the difference in the linear expansion coefficient between the iron plate and the decorative film, resulting in unevenness on the surface of the door.

[0008] In addition, since the iron plate is used as the base material, when water infiltrates from the end, it oxidizes from the end of the iron plate.

Further, there is a problem that the outer surface plate on the door body surface becomes uneven due to the foam-filled heat insulating material.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a refrigerator door body which is straight with no irregularities on the door body surface, can have a deep gloss, can respond to various designs, and does not oxidize. Is provided.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a door of a refrigerator according to the present invention has a front surface which is deformed when foaming a heat insulating material.
A transparent layer serving as a base material having a thickness to withstand , a colored resin plate having a colored layer on the back surface, a frame provided around the entire periphery of the colored resin plate, and an inner plate provided to face the colored resin plate And a heat insulating material foam-filled between the colored resin plate, frame, and inner plate.

[0012] Further, when the colored resin plate has a heat insulating material foamed on the front surface,
A door body of a refrigerator, which is a resin decorative board having a transparent layer serving as a base material having a thickness to withstand the deformation, a transfer printing layer on the back surface, and a print protection layer on the back surface of the transfer printing layer.

Further, when the colored resin plate has a heat insulating material foamed on its front surface,
A door body of a refrigerator, which is a laminated resin decorative board having a transparent layer serving as a base material having a thickness enough to withstand deformation, a translucent layer including a transparent portion and a printed portion in the middle, and a colored layer on the back surface.

A transparent layer is provided on the front surface and a transparent portion is provided in the middle.
The product of laminating a translucent layer consisting of a printing unit and a coloring layer on the back
A layer resin decorative plate, an outer plate disposed on the rear surface of the laminated resin decorative plate, and a frame body provided on the entire circumference of the laminated resin decorative plate-outer plate, a plate inner provided so as to face the outer plate And a heat insulating material filled and foamed between the outer plate, the frame, and the inner plate .

[0015] Also, the outer printed with transparent layer on the front surface, the laminated resin decorative laminate translucent layer made of a printing unit the transparent portion on the back surface was laminated plate, to the front and arranged on the back surface of the laminated resin veneer Board, a frame provided around the entire periphery of the laminated resin decorative board / outer board, an inner board provided opposite to the outer board, and heat insulation foam-filled between the outer board / frame / inner board. It is provided with a configuration of a material.

[0016]

The door of the refrigerator according to the present invention has the above-described structure.
While giving gloss in the transparent layer located in front of the coloring layer,
Gloss can have depth.

Also, since the surface is composed of one part,
Without trapping the decorative film on the iron plate, it traps air bubbles and dust, does not open irregularities on the adhesive, does not open the irregularities on the surface of the iron plate, etc. The adhesive does not peel off due to the difference in the coefficient of linear expansion at the time, and the door surface does not become uneven.

Further, the resin plate does not deform when the heat insulating material is foamed.
Since the thickness as the base material is secured, there is no unevenness due to the foam-filled heat insulating material, and the weight can be reduced as compared with the conventional iron plate door.

Further, since a translucent layer is provided on the colored resin plate, a printed portion is provided in front of the colored layer, so that a three-dimensional effect can be obtained by a front-back feeling.

Further, since the resin plate is used, it is not oxidized.
