Summary of the invention
The objective of the invention is to consider the problems referred to above and a kind of manual dexterity height is provided, the production efficiency height, the qualification rate height, the control panel assembly of microwave oven of environmental protection,
Technical scheme of the present invention is: a kind of control panel assembly of microwave oven, comprise touch pad, inductive layer, control box and computer plate, wherein inductive layer and computer plate are packed in respectively on the front-back of control box, touch pad is packed in the control box front and places the front side of inductive layer, answer touch pad to be provided with some membrane keyboards, it is characterized in that described inductive layer made by the conductive material of soft and transparent, the set membrane keyboard of corresponding touch pad is provided with induction zone on the inductive layer, be provided with induction electrode in the induction zone, be provided with holding wire around the induction zone, one end of holding wire is connected with induction electrode, and the other end is electrically connected with the computer plate.
Above-mentioned inductive layer is made by tin indium oxide material.
The set induction zone of corresponding inductive layer is provided with loophole on the above-mentioned control box, and corresponding loophole is provided with backlight on the computer plate.
Above-mentioned touch pad is made by transparent acrylic or lucite.
The front of above-mentioned control box is a curved surface.
The top of above-mentioned computer plate is provided with display screen, and control box top and display screen correspondence position are provided with opening, between opening and the display screen sealing ring are housed.
Screen layer is equipped with in the inboard of above-mentioned computer plate.
The present invention is owing to adopt the conductive material of soft and transparent to replace pcb board as inductive layer, its material softness, production process is not yielding, induction electrode in the induction zone can be fine corresponding with the set membrane keyboard of touch pad, the sensitivity that makes the computer plate detect capacitance between staff and the electrode slice improves greatly, and fine being mounted on the control box of soft inductive layer energy, can not produce the gap between the two, improved the qualification rate of control panel assembly of microwave oven greatly, simultaneously, the inductive layer material is than more environmental protection of pcb board; In addition, the present invention can satisfy the demand of curved face type control box, has greatly enriched the appearance design and the function design of control panel assembly.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is the structural representation of inductive layer among Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to Fig. 2, Fig. 3, control panel assembly of microwave oven of the present invention, comprise touch pad, inductive layer 2, control box 3 and computer plate 4, wherein inductive layer 2 and computer plate 4 are packed in respectively on the front-back of control box 3, touch pad 1 is packed in control box 3 fronts and places the front side of inductive layer 2, answer touch pad 1 to be provided with some membrane keyboards 10, described inductive layer 2 is made by the conductive material of soft and transparent, corresponding touch pad 1 set membrane keyboard 10 is provided with induction zone 20 on the inductive layer 2, be provided with induction electrode in the induction zone 20, be provided with holding wire 5 around the induction zone 20, an end of holding wire 5 is connected with induction electrode, and the other end is electrically connected with computer plate 4.When staff contact membrane keyboard 10, the electric capacitance change between the induction electrode of staff and inductive layer 2 passes to computer plate 4 by holding wire 5, and computer plate 4 carries out passing to the relevant instruction of micro-wave oven after the relevant treatment, thereby finishes the function of cooking.Certainly, during regional outside staff touches the membrane keyboard of touch pad 1, also can form electric capacity between staff and the inductive layer, capacitance also can change with setting about the touch degree, but because its adjacent domain does not have holding wire or does not have holding wire to be connected on the computer plate, thereby can not make that the computer plate instructs, avoid faulty operation.
