Description

An injection molded object for luminous display part of refrigerator and mufacturing method of the same}

The present invention relates to an injection molded product for a light emitting display of a refrigerator and a method of manufacturing the same.

Generally, a refrigerator is a home appliance having a storage space shielded by a door to store food at a low temperature. The refrigerator is cooled by circulating the refrigerant and causes the cooled air to circulate inside the storage space. Ensure food is stored optimally.

Such refrigerators are gradually becoming larger and more versatile in accordance with changes in dietary life and quality of products, and refrigerators having various structures and convenience devices for the convenience of users have been released and developed.

Accordingly, recently released refrigerators are provided with a plurality of operation buttons on the main body and the door and a display showing an operation state of the refrigerator according to a user input using the operation buttons for multifunction. The user can input various control commands through the operation button while checking the operation state through the display.

On the other hand, the operation button and the display as described above to form a light through the backlight to facilitate the user's visual recognition in the dark or at night.

Korean Patent No. 10-0411518 discloses a display device and a manufacturing method of an electronic product for improving visual recognition of a user.

Referring to the prior art, a first frame is formed by attaching or printing a first frame, which transmits light of a luminaire and is formed on a front surface of a transparent plate having a predetermined thickness, and is attached to or printed on the rear surface of the transparent plate. A second frame that transmits light toward the first frame side is attached or printed.

In the formation of the first frame, a reflective layer is printed on one side of the transparent plate, and the display code is printed on the entire surface of the reflective layer.

In addition, when the second frame is formed, a background color layer serving as the background of the display symbol is printed, and a white layer for printing the background color of the background color layer is printed on the front of the background color layer, and on the front of the white layer. A light shielding layer is printed to block light generated from the luminaire to portions except for the reference numeral.

In addition, a reflective layer is further printed on the front surface of the light blocking layer to increase the brightness of the light by reflecting the light generated from the luminaire, and the display device to diffuse the light generated from the luminaire on the front surface of the reflective layer. A diffusion layer formed of the same size as is further printed.

When light is irradiated from the lighting device through the above configuration, the display code formed in the first frame is exposed to the outside, so that the user can easily identify the display code in a dark place or at night, and the light shielding of the second frame is performed. By preventing light from being exposed to the periphery of the display code by the layer, light leaking out of the display code is prevented.

However, in the prior art, in order to create the above effects, a plurality of flat plate-shaped frames made of an injection molded product are subjected to a plurality of processes in which a display code and a background color, a white layer, a diffusion layer, and a blocking layer are attached in the form of a print or a film. .

Therefore, the time required for manufacturing the display device is increased due to the plurality of work processes as described above, and thus there is a problem that productivity is lowered.

In addition, the display code, the background color, the white layer, the diffusion layer, the blocking layer, and the like are printed by screen printing or formed in a film form. Therefore, the first frame and the second frame has a problem that the printed surface should be formed only in a plane.

The present invention provides an injection molded product for a light emitting display of a refrigerator, which is not limited to a flat plate shape.

Another object of the present invention is to provide an injection molded product for a light emitting display of a refrigerator in which a work process is reduced through coating and laser processing of paint.

Still another object of the present invention is to provide a method of manufacturing an injection molded part for a light emitting display of the refrigerator as described above.

The present invention provides a base that is injection molded in a form corresponding to a light emitting display of a refrigerator, a colored layer formed by spraying paint on the entire surface of the base, and the colored layer is removed by laser processing, and the base is laser processed. It is characterized in that it comprises a recognition unit formed through a diffusion process through which the user can recognize.

In addition, a method of manufacturing an injection molded part for a light emitting display part of a refrigerator according to the present invention includes a base forming step of injection molding a transparent material in a form corresponding to the light emitting display part of a refrigerator, and spraying paint onto the entire surface of the base. And a recognition layer forming step of forming a colored layer forming step and a pattern recognizable by a user through laser processing on the colored layer and the base.

According to the present invention, the base is injection molded in a form corresponding to the light emitting display of the refrigerator, and the paint is evenly sprayed on the entire area of the injection molded base to form a colored layer.

The colored layer performs a light shielding function so that light emitted from the light emitting display unit does not leak to the outside, and a portion of the colored layer is removed through laser processing and a user-recognizable pattern is formed on the base. When the light is irradiated, the processed pattern is exposed to the color of the irradiated light.

In addition, when the light is not irradiated, the user can recognize the processed pattern through the diffusion-printed printing pattern, so that the injection molding for the light emitting display unit can be easily formed without the need of forming a separate light shielding layer or a diffusion layer. There is an advantage.

In addition, by forming a printing pattern formed by diffusion while removing the colored layer through the laser processing as described above, even if the surface on which the printing pattern is formed has a flat surface as well as a bend can be easily formed.

Therefore, it is possible to give a three-dimensional impression to the injection molding, the light emitting display can have a more aesthetic sense, there is an advantage that it is possible to form a three-dimensional design of more various forms.
