Description

[Detailed explanation of the idea] [Industrial application field] This idea is related to refrigerator doors.

[Conventional technology]

FIG. 5 is a perspective view of a conventional refrigerator shown in Japanese Utility Model Publication No. 60-39742, and FIG. 6 is an enlarged sectional view taken along the line - in FIG. In Figures 5 and 6, 1 is a door provided on the front of the refrigerator body with insulation properties, 2 is a door outer panel made of painted steel plate, and 3 is a cross section fitted to the outer periphery of the door outer panel 1. Almost U-shaped frame member, 4
Reference numeral 5 indicates a heat insulating material such as polyurethane foam filled with foam inside the door body 1 composed of the door outer panel 2 and the frame member 3, and 5 indicates the inside of the door whose outer periphery is fixed to the inner surface of the frame member 3 with screws. A plate 6 is a gasket fixed to the frame member 3 to shut off cold air inside the refrigerator from the outside. 7 is a handle base fixed to one side of the front surface of the door outer panel 2 over the entire height; 8 is a decorative board made of a transparent plate subjected to secondary processing of hot stamping and silk screen printing from the back side; The decorative board 8 is fixed to the front surface of the handle base 7 with an adhesive such as double-sided tape (not shown). Reference numeral 9 denotes a handle for opening and closing the door body 1, and the handle 9 is composed of a handle body 12 in which a handle portion 10 and a base portion 11 are integrally formed, and a handle cover 13 fitted to the handle body 12. The handle body 12 is fixed to the door outer panel 2 with screws 14 via the handle base 7 and the decorative panel 8. Reference numeral 15 denotes an anchor nut having a main body 16 embedded in the door body 1 so as to withstand the strength during use when holding the handle 10 of the handle 9 to open and close the door. The screw 14 is tightened.

[Problem that the invention attempts to solve]

The conventional refrigerator door is constructed as described above.
Since a painted steel plate was used as the outer panel of the door, even if an attempt was made to form a convex part with a flat front surface on the outer panel of the door, the paint would crack during the drawing process, damaging the appearance. The exterior design has to be improved by using a handle base and decorative plate made of parts, which increases the cost. Also, when installing the handle, anchor nuts are used and the handle attachment screws are tightened to these nuts. However, there were problems in that the number of parts increased and the cost increased.

This invention was made in order to solve the above-mentioned problems, and the purpose is to provide a refrigerator door that has an excellent design, is low in cost, and has a high practical price.

[Means for solving problems]

In the refrigerator door according to this invention, the door outer panel is made of a vacuum-formed synthetic resin sheet laminated with a back layer serving as a base material, an intermediate layer with excellent design, and a transparent surface layer. A convex portion with a flat front surface is integrally formed over the entire height on one side of the door outer panel, and a handle is fixed to the front surface of this convex portion.

[Effect]

In the refrigerator door body of this invention, the outer panel of the door was formed by vacuum forming a laminated sheet of synthetic resin, so it was possible to easily form a convex part with a flat front surface, and it was also possible to perform secondary processing on the flat front surface. By applying
It is possible to eliminate the handle base and decorative panel of conventional doors, making it possible to manufacture doors with excellent design at low cost.In addition, the convex part can be used to prevent the handle body from turning when tightening screws, and the handle body The strength of the door outer panel near the base can be easily increased, anchor nuts can be eliminated, and the number of parts can be reduced.

〔Example〕

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a perspective view of a refrigerator equipped with a door according to an embodiment of the invention, and FIG. 2 is an enlarged vertical sectional view taken along the line - in FIG. In Figs. 1 and 2, the same reference numerals as in Figs. 5 and 6 indicate the same or corresponding parts, and 2 indicates the back layer serving as the base material, which is made of ordinary acrylic butadiene styrene (ABS) resin, and the intermediate layer made of ABS resin. Vacuum forming is performed using synthetic resin sheets made by laminating the back layer, intermediate layer, and surface layer, with the surface layer made of transparent resin such as acrylic resin, and the surface layer made of transparent resin such as metallic resin mixed with aluminum. Door outer panel 17 is door outer panel 2
It is a convex part integrally formed on one side part over the entire height of the door outer panel 2, and a concave part 18 slightly recessed through a step is formed on the front part of the convex part 17.
It is formed at a position facing the base 11 of No. 2.
By fitting the base 11 into the recess 18, the mounting position of the handle body 12 is determined and the handle body 12 is prevented from rotating when the screw 14 is tightened. On the other hand, since the step with the height dimension H is provided, the strength of the door outer panel 2 at the attachment part of the handle 9 is increased. 19 is the convex portion 1 of the door outer panel 2
7 is a printed design section formed by directly applying hot stamping and silk screen printing to the front surface, and with this design section 19, there is no need to use a handle base or decorative board made of separate parts like in the past.
It is possible to obtain a design effect that is equal to or better than conventional ones, and by eliminating the handle base and decorative board, the refrigerator door can be manufactured at a low cost. Further, due to the recess 18 provided integrally with the convex portion 17, anchor bolts for attaching the handle 9 can also be eliminated, resulting in a refrigerator with fewer parts and a lower cost.

3 and 4 show other embodiments of this invention. In FIG. 3, 20 is the convex portion 1 of the door outer panel 2.
The notch recess 20 is formed at a position corresponding to the handle part 10 of the handle body 12, forms a guide for the handle part 10, and extends the handle by the height of the front surface of the convex part 17. Even if the height of the handle 9 is reduced, the function of the handle 9 as a handle can be sufficiently obtained, and the dimension of the handle 9 that protrudes outward can be made shorter than the height of the handle of a conventional refrigerator. To easily produce a refrigerator door with an excellent design by eliminating the appearance.

[Effect of idea]

As explained above, according to this invention, the outer panel of the door can be formed by vacuum forming a synthetic resin sheet in which a back layer, an intermediate layer with excellent design, and a transparent surface layer are laminated. At the same time, a convex part can be provided on one side, and a printed design part can be easily provided on the flat front surface of the convex part, which makes it possible to eliminate the conventional handle base and decorative plate. By providing a concave part in the convex part,
The conventionally used anchor nut can be abolished, the number of parts is small, and therefore, it is possible to provide a refrigerator door that is inexpensive, has a good design, and has great practical value.
