Abstract
The utility model discloses a touch panel of household electric appliances. The touch panel comprises a circuit board and a touch insulating board, wherein a touch control circuit is arranged on the circuit board; a pit is formed on the inner side of the touch insulating board; and a conductor electrically connected with the touch control circuit is arranged in the pit. The touch panel has the benefits of lower cost and higher reliability.
Description
Technical field
The utility model relates to a kind of household electrical appliance touch panel.
Background technology
Along with science and technology development, existing increasing now household electrical appliance adopt contact type panel, as for present electromagnetic oven, its contact type panel adopts crystallite plate or tempered glass, it is expensive to restrict touching technique applying on equipment such as electromagnetic oven, moreover in a single day crystallite plate and tempered glass break, and the electromagnetic oven complete machine damages, can not work, cause with protecting complaint.
For other household electrical appliance, also there is same problem, need reduce cost and improve and do aspect the reliability further to improve.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of cost low, the high household electrical appliance touch panel of reliability.
Its technical scheme is as follows:
A kind of household electrical appliance touch panel comprises circuit board, is provided with touch control circuit on circuit board, also includes the touch insulcrete, and the inboard of this touch insulcrete is provided with recess, is provided with electric conductor in recess, and this electric conductor and touch control circuit are electrically connected.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
The bottom connection of described electric conductor and described recess touches.
Described touch insulcrete is for touching offset plate.
Described touch insulcrete is located at the top of described circuit board and is parallel to each other with described circuit board.
Between described touch insulcrete and circuit board, be provided with power spring, described electric conductor in the form of sheets, power spring is pressed on described electric conductor in the recess of described touch insulcrete inboard, electric conductor is electrically connected by power spring and described touch control circuit.Power spring is used for sheet metal is withstood on plastic cement spare inwall, play electric action, the capacitance variations that produces between human body and the sheet metal is passed to inductance capacitance on the circuit board, a perhaps direct electric conductor, can withstand between glue spare and the circuit board and get final product, promptly power spring and sheet metal can integrated setting.
Described electric conductor also can be column, and the one end is pressed on the bottom of described recess, and the other end and described touch control circuit are electrically connected.
The bottom of described recess is 1 to 2 millimeter with respect to the distance between the outside surface of described touch insulcrete.
Principle of the present utility model is:
Utilize the low cost and the plasticity of offset plate, take the structure of clearance position (being recess), make between power spring and the human body apart from furthering, like this behind finger touch, produce capacitive coupling with electric conductor, and changes in capacitance reaches circuit board by power spring, and the inductance capacitance on the circuit board changes, and carries out relevant operation.
The utility model has the advantages that:
1, adopts offset plate as touching insulcrete, reduced the cost of contact type panel;
2, with offset plate as touching insulcrete, its physical strength is far longer than tempered glass and crystallite plate, in transportation and use, not fragile, reliability is higher.

Description of reference numerals:
1, circuit board, 2, touch insulcrete, 3, recess, 4, electric conductor, 5, power spring.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
A kind of household electrical appliance touch panel (household electrical appliance described in the present embodiment are electromagnetic oven), as shown in Figure 1, it comprises circuit board 1, on circuit board 1, be provided with touch control circuit, also include and touch insulcrete 2, the inboard of this touch insulcrete 2 is provided with recess 3, is provided with electric conductor 4 in recess 3, and this electric conductor 4 is electrically connected with touch control circuit.
Wherein, described touch insulcrete 2 is for touching offset plate, and the thickness of this touch offset plate is 3mm, its inboard recess 3 recessed 2mm, and making and touching the thickness of offset plate at the recess place only is 1mm, the distance that touches between insulcrete 2 and the circuit board 1 is 10mm; Touch insulcrete 2 is located at the top of circuit board 1 and is parallel to each other with circuit board 1, between touch insulcrete 2 and circuit board 1, be provided with power spring 5, electric conductor 4 in the form of sheets, adopt sheet metal in the present embodiment, power spring 5 is pressed on the bottom of the recess 3 that touches insulcrete 2 inboards with electric conductor 4, and electric conductor 4 is electrically connected with touch control circuit by this power spring 5.
The principle of present embodiment is:
Utilize the low cost and the plasticity of offset plate, take the structure of clearance position (being recess 3), make between power spring and the human body apart from furthering, like this behind finger touch, produce capacitive coupling with electric conductor 4, and changes in capacitance reaches touch induction circuit on the circuit board 1 by power spring 5, and the inductance capacitance in the touch induction circuit changes, and carries out relevant operation.
The advantage of present embodiment is:
1, adopts offset plate as touching insulcrete 2, reduced the cost of contact type panel;
2, with offset plate as touching insulcrete 2, its physical strength is far longer than tempered glass and crystallite plate, in transportation and use, not fragile, reliability is higher.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
