A kind of guidance panel that is used to touch control
Technical field
The utility model relates to a kind of guidance panel, particularly a kind of guidance panel that is used to touch control that can be applicable on the products such as electric pressure cooker, electric cooker, electromagnetic oven.
Background technology
Present guidance panel adopts sandwich construction; Form by printing rete, printing ink layer and substrate layer; Its course of processing is at first on film, to print contents such as button, pattern; Be pressed into the shape that needs to film then, then be put into film in the mould, the interior injection moulding substrate material of last past mould also makes it moulding.There is following shortcoming in existing guidance panel: multi-layer structure process is complicated, and cost is than higher; Substrate layer is easy to generate delamination with the printing rete; The film printing content shows that through very thin film the outward appearance stereovision is not strong again.
Summary of the invention
For solving problem and the defective that existing guidance panel exists, the utility model provides the guidance panel that is used to touch control that a kind of technology is simple, cost is low, the outward appearance stereovision is strong.
The technical scheme of the utility model is: the guidance panel that is used to touch control of the utility model; Include transparent or semitransparent substrate; Substrate includes viewing area and key zone; Wherein the zone of the inner surface of substrate except that the viewing area is sprayed with the bottom surface skin of paint, and the outer surface of substrate is printed with the button patterned layer in the position of key zone.
Be fixed with wiring board on the aforesaid substrate, wiring board is provided with display screen and induction coil, and wherein display screen is located at the below of viewing area, and the displaying contents transmission display district of viewing area shows; Induction coil is located at the below of key zone, and during the touch key-press district, induction coil produces induced signal.
Above-mentioned wiring board passes through screw on the screw post of substrate.
Above-mentioned wiring board through set button bit spiral-lock on shell, shell again through screw on the set screw post of substrate.
The utility model guidance panel is because to adopt substrate be whole, the structure that skin of paint and button patterned layer only are provided with on regional area, so technology is simple, reliably, cost is low, do not have delamination problems; Simultaneously, the bottom surface skin of paint shows that through transparent or semitransparent substrate stereovision is more intense again.The utility model is that a kind of design is ingenious, function admirable, and convenient and practical being used to touches the guidance panel of control.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment 1:
Like Fig. 1, shown in 2: the guidance panel that is used to touch control of the utility model; Include transparent or semitransparent substrate 1; Substrate 1 includes viewing area 11 and key zone 12, is fixed with wiring board 4 on the substrate 1, and wiring board 4 is provided with display screen 5 and induction coil 6; Wherein display screen 5 is located at the below of viewing area 11, and the displaying contents transmission display district 11 of viewing area 11 shows; Induction coil 6 is located at the below of key zone 12; During touch key-press district 12; Induction coil 6 produces induced signal, and wherein the zone of the inner surface of substrate 1 except that viewing area 11 is sprayed with bottom surface skin of paint 2, and the outer surface of substrate 1 is printed with button patterned layer 3 in the position of key zone 12.
In the present embodiment, above-mentioned wiring board 4 is fixed on the screw post 13 of substrate 1 through screw 7.
Embodiment 2:
As shown in Figure 3, the difference of present embodiment and embodiment 1 be wiring board 4 through set button bit 81 spiral-locks on shell 8, shell 8 again through screw on the set screw post of substrate 1.
