Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device that clearly displays the process of a washing machine and also provides a light source guide in the display section to improve installation workability and prevent light dispersion. It is.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figure 1, 1 is the outer frame of the single-tub washing machine, 2 is the upper frame provided on the outer frame 1, and 3 is the upper frame 2.
A top mark provided on the front surface, 4 an opening/closing lid, 5 an operation switch provided on the top mark 3, and 6 a display section for displaying the washing process, rinsing process, and dehydration process by operating the operation switch 5. This display section 6 is a light source display, and normally lights up and blinks. 7 is a decorative board provided with a window in the display portion 6 and provided on the top mark 3.

Next, the configuration of the display section 6 will be explained with reference to FIGS. 2 and 3. A display hole 8 is provided in the top mark 3, and the display part 6 itself, which is long in the horizontal direction, is attached to the display hole 8. The display part 6 is a molded product made of different materials, and the material and color tone are changed between the front side A and the back side B. In the embodiment, the front side A is colored transparent and molded with dark red and transparent, and the back side B is molded with a black opaque material. On the back side of the back side B, there is a guide groove/light dispersion prevention wall 9.
A light source window 10 is formed in the interior surrounded by a prevention wall 9. Reference numeral 11 denotes a light source such as a light emitting diode, which is located within the prevention wall 9 and is visible from the surface. The light source color uses the same color system as the color of the colored transparent parts.

The light source 11 is attached to the print base 12,
Attach the mounting screw 1 to the mounting boss 13 provided on the display section 6.
4, the whole is fixed. The height of the mounting boss 13 is the same as that of the prevention wall 9. Reference numeral 15 denotes a pattern foil provided on the print base 12 surface, which serves to guide electrical signals, and is further guided to the controller section by a lead wire 16.

According to the above configuration, since the display part 6 is composed of a series of molded parts, the installation work of the display part 6 is handled as one part, and the waterproof test of the top mark part is also done in one test because it is one part. The number of times is enough. Also, in terms of workability, when attaching the display section 6 and the print base 12, the display section 6
Since the mounting boss 13 is provided on the top mark 3, it is possible to attach and join the display section 6, print base 12, and light source 11 to the top mark 3 after completing the finished product.
This makes it possible to reduce the size of the assembly line. In addition, the display section 6, print base 12, and light source 11
It becomes possible to consider assembly with the completed product. Furthermore, since the display part 6 is formed by molding different materials, if the guide groove/light dispersion prevention wall 9 for the light source 11 is made of opaque black and is placed on the back side of the colored transparent part, the light source 11
The light passes straight through the light source window 10 without being dispersed in the outer circumferential direction. Therefore, it is possible to prevent the phenomenon of blurring due to the dispersion of light, making it possible to see clearly and giving an extremely sharp design feel. Also, surface side A
Since the back side of the colored transparent part is entirely covered with a colored opaque material on the back side B, the inside of the display part 6 cannot be seen at all, and the light source 1 cannot be seen from the light source window 10.
Only 1 is visible. Furthermore, when the color tone of the colored transparent part on the front side A is red and transparent, the single color of the light source 11 is made up of the same color system of red, and the red of the colored transparent part on the back side B is set to be more red than the red of the light source 11. By making it darker, when the light source 11 is not lit, the colored transparent color of the display part 6 is dark, so the individual color of the light source 11 is absorbed and its presence is lost, and when the light source 11 is lit, a part of the colored transparent part is When it shines, it becomes possible to give it a sense of design. In addition, when the display unit 6 is exposed to direct sunlight, if the colored transparent color is light, it will be absorbed by the sunlight color and the light source 1
The brightness of 1 is also absorbed, making it unclear to see the light. Therefore, it is desirable to use a very dark color for the colored transparent portion. If a dark color is used, the absorption power of sunlight is suppressed, and the lighting of the light source 11 can be relatively confirmed. Furthermore, if the heights of the prevention wall 12 and the mounting boss 13 of the display section 6 are made the same, the print base 12 can be constructed on the same plane just by being assembled, and the gap between the light source 11 and the display section 6 can be kept constant. This makes it easy to assemble.

As is clear from the above examples, the present invention
Particular consideration has been given to the structure of the display section, thereby providing an excellent display device with reliable display and easy installation of a light source.
