In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a perspective view of a touch panel for a storage device according to an embodiment of the present invention, FIG. 2 is a rear perspective view of the touch panel for a storage device according to an embodiment of the present invention, and FIG. 3 is an embodiment of the present invention. 4 is an exploded perspective view of a touch panel for a storage device, and FIG. 4 is a cross-sectional view of the touch panel for a storage device according to an embodiment of the present invention.

1 to 4, a touch panel for a storage device according to an embodiment of the present invention includes a housing 10 and an FPCB 20.

The housing 10 forms the entire outline of the touch panel and supports the FPC 20.

In this case, the housing 10 may be applied in various shapes and various materials.

The FPC 20 is formed on the front side of the housing 10.

In particular, the FPC 20 is formed on the front side of the housing 10 by various methods, it is preferable to be bonded and fixed to the front side of the housing 10.

In addition, the FPC 20 is made of a flexible material. This means that the FPC ratio 20 is formed thin enough to bend easily.

Thus, the height of the entire touch panel can be reduced.

In addition, the FPC 20 forms a plurality of touch circuit patterns 22.

The touch circuit pattern 22 is formed at different positions on the FPC 20 to generate a corresponding signal when a touch is applied from the outside.

Here, the housing 10 in which the FPC 20 is formed is provided as a touch panel in the storage device, and the storage device is a refrigerator, a kimchi storage, or the like.

Of course, the FPC 20 is formed in various shapes, and is not limited to the number.

Meanwhile, the housing 10 includes a printed circuit board 30.

The printed circuit board 30 is connected to the FPC ratio 20 to receive a signal generated from the FPC ratio 20.

In addition, the printed circuit board 30 receives power from the outside. Of course, the FPC 20 may be directly supplied with power from the outside.

In particular, the printed circuit board 30 is preferably formed inside the housing 10 to be protected from the outside.

At this time, the printed circuit board 30 is provided inside the housing 10 by various methods such as double injection or separation of the housing 10.

On the other hand, the FPC 20 forms the front deco 40 on the front side. The front deco 40 serves to protect the FPC.

In particular, the front deco 40 is fixed to the housing 10 by a variety of methods, such as adhesive.

In addition, the front deco 40 has a mode member 42 which is plotted for each operation mode.

In particular, the front deco 40 is made of a transparent film paper, the portion except the mode member 42 is coated with a set color.

At this time, the mode member 42 shows the set operation mode of the storage device in letters or figures.

In addition, the housing 10 forms a sector portion 50 corresponding to each of the mode members 42.

This sector portion 50 recesses or sets the set area into a hole shape. For convenience, the sector portion 50 is shown as having passed through a small hole in the large recessed area.

This sector portion 50 coincides with each of the mode members 42 of the front decor 40.

Each sector portion 50 includes a light emitting element 60 for emitting light.

Thus, when the light emitting device 60 of the corresponding sector portion 50 emits light, light is emitted outward along the trajectory of the mode member 42 of the front decor 40.

Thereby, the visibility of the mode member 42 is improved.

Here, the light emitting device 60 may be an LED or the like, and may be directly connected to an external power source, but is connected to the printed circuit board 30 through a small hole forming the sector part 50.

That is, the light emitting device 60 emits light by an external power source supplied to the printed circuit board 30.

In addition, the FPC 20 may weaken the visibility of the mode member 42 when the sector portion 50 is covered.

Thus, the FPC 20 passes through the opening hole 70 so as to correspond to each of the sector portions 50.

In particular, the FPC 20 forms the touch circuit pattern 22 along the edge of the opening hole 70.

This is to maintain or improve the touch sensitivity by concentrating the touch circuit pattern 22 along the edge of the opening hole 70 closest to the mode member 42.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. I will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
