[Prior art]
FIG. 7 shows a door of a conventional refrigerator-freezer. FIG. 8 shows a zz section of FIG. 7 and 8, a heat insulating material 5 is filled inside the design panel 1 by sandwiching the upper and lower sides of the design panel 1 with an upper cap 2 and a lower cap 4. The upper cap 2 also serves as a handle 3 for handling.
[0003]
An ornament 3a is provided on the front side of the handle 3 to enhance the design. Ornaments are decorations that have a metallic luster on a part of the handle, such as a method in which aluminum-deposited foil is transferred, for example, to be placed for the purpose of improving design.
[0004]
FIG. 9 shows a method of forming the ornament 3a as a design on a part of the handle 3 provided on the panel 1 in the door of the conventional refrigerator-freezer by using a design molding die 7. A foil 12 shown as a sheet printed with aluminum or the like is filled between the design-side mold surface 9 and the ornament-side mold surface 10, and a resin part is injected from the resin spout 8 into the design mold 7. 11 shows the insert molding for forming the foil 12 at the same time.
[0005]
A technique similar to the related art is disclosed in Japanese Patent Application Laid-Open No. 2001-116435 shown in FIG. 10. As shown in the figure, the surface of a design panel 1 made of resin and having a convexly curved surface is formed. The handle 3 provided with a substantially circular handle portion 29 was provided, and the handle 3 was constituted by a substantially L-shaped mounting portion formed integrally with the handle portion 29. In the example of FIG. 10, when the handle 3 and the handle attachment portion 30 are designed as members to be colored differently according to design requirements, there is a request to cover the handle 3 and color the handle attachment portion 30.
[0006]
FIG. 11 shows a step of painting the ornament 3a of the handle 3. In step 100, a masking jig for covering the unpainted part of the handle 3 and the upper cap 2 is attached. In the next step 101, the ornament 3a is painted, and the ornament 3a is dried for the purpose of forming a coating film. In the next step 102, the masking jig is removed from the handle 3 in the step 103. In FIG. 12, in the case of insert molding and hot stamping, there are many restrictions on the shape of the part to be molded. An example where only ornaments can be placed is shown.
[0007]
FIG. 12 is a cross-sectional view of the case where the foil 12 is formed simultaneously with the resin component 11 from the resin filling port 8 to be injected into the design molding die 7 as viewed from the direction of the arrow in FIG. As shown in FIGS. 12 (b) and 12 (c), FIG. 12 (b) corresponds to a case where the length L of the foil 12 is shortened below the center point of the R portion in FIG. 12 (a). In FIG. 12 (c), the foil 12 is beautifully formed on the handle 3 in a horizontal straight line, but in FIG. 12 (c), which corresponds to the case where the length L of the foil 12 is increased downward from the center point of the other R portion, When it is traced in the lateral direction, it is wavy up and down and formed on the handle 3.
[Problems to be solved by the invention]
As shown in FIG. 9, there is a conventional method of placing an ornament as a design accent on a part of a door handle of a refrigerator-freezer, in which a sheet printed with glossy aluminum or the like is injected into a mold when the resin is filled. Insert molding to insert and mold at the same time, secondary processing of molded parts, that is, hot stamping and painting to transfer the design you want to decorate by heating and pressing the surface of the molded part newly from another print medium etc. Etc. exist. In the two processing methods, insert molding and hot stamping, there are many restrictions on the shape of the part to be molded, and only one side of the part, or R as shown in FIG. However, there is a problem that the ornament can be arranged only up to the R stop where it comes into contact with the tangent to the front or side. In addition, when it is desired to implement a design in which a design is prioritized over other product elements in a refrigerator, there is a problem that the shape must be changed due to processing technology restrictions.
[0008]
In the method using hot stamping, when the shape of a processed part (such as a handle) is complicated, it is difficult to uniformly transmit temperature and pressure to the foil over the entire surface, so that the adhesive strength of the foil is reduced and the foil is easily peeled.
[0009]
When the door is closed like a drawer door of a refrigerator, the front of the door becomes a design, and when the door is pulled out, when the upper surface of the door also becomes a design, the ornament cannot be processed on the upper surface, thereby impairing the design.
[0010]
Also, in the processing of ornaments by painting, the whole part is sprayed with paint, so if you want to process part of the handle in a point manner, do not cover the surface of the part you do not want to paint with masking etc. In addition, the processing cost of attaching and detaching the masking jig is increased, and as shown in FIG. 11, in a mass-produced product, a large number of masking jigs are applied to a plurality of parts to be painted almost simultaneously. There is a problem that it becomes necessary and a jig manufacturing cost is required.
[0011]
The present invention has been made in order to solve the above-described problems, and provides an inexpensive, high-design refrigerator door, and a hand-holding ornament in consideration of a manufacturing method and recyclability. The purpose is to produce designed panels as refrigerator doors.
[0012]
