Embodiment
Embodiment:
Structural representation of the present invention such as Fig. 1,3, shown in 4, include panel 1, be installed in the knob assembly 2 of panel 1 end face, be installed in the touch sensible electrode 3 and the circuit board 4 of panel 1 bottom surface, wherein knob assembly 2 includes touch sensible parts 21, knob main body 22 and fixed part 23, sense of touch answers parts 21 to be installed in the bottom of knob main body 22, fixed part 23 is permanent magnets, it is installed on the knob main body 22, be equiped with permanent magnet 41 on the circuit board 4, the permanent magnet 41 of installing attracts each other and is fixed on the panel 1 on the fixed part 23 of knob assembly 2 by installing on it and the circuit board 4, and the touch sensible electrode 3 that is installed in panel 1 bottom surface answers the position of parts 21 corresponding with the sense of touch of the bottom that is installed in knob main body 22.In the present embodiment, panel 1 is a microcrystal glass plate.Above-mentioned touch sensible parts 21 are made by the good conductor material of electricity.
Above-mentioned touch sensible parts 21 are made with knob main body 22 one, or are assembled together after separately making again.In the present embodiment, touch sensible parts 21 and knob main body 22 are separated and are assembled together after making again.
Above-mentioned knob assembly 2 is installed in the operating area 11 of panel 1 end face, in operating area 11, be printed on corresponding culinary art in position or/and operational label symbol 12 corresponding to each touch sensible electrode 3, as: label symbols such as " cooking congee ", " chafing dish ", "+", "-".
Above-mentioned touch sensible electrode 3 is provided with some groups, and each touch sensible combination of electrodes in every group of touch sensible electrode 3 is arranged in a toroidal, and each touch sensible electrode be shaped as circular, square.
Shape, the sizableness of each touch sensible electrode in above-mentioned every group of touch sensible electrode 3 and the touch sensible parts 21 of knob main body 22 bottoms.
Above-mentioned knob assembly 2 is installed in the operating area 11 of panel 1 end face, and touch sensible electrode 3 is printed on the film Trackpad 5, and film Trackpad 5 sticks on panel 1 bottom surface and about in the of 11 corresponding position with operating area.In the present embodiment, be provided with 8 touch sensible electrodes 3, form an annular with the spacing that equates.Operating area 11 inherent positions of answering with each touch sensible electrode pair on the glass-ceramic panel 1 are printed on corresponding label symbol, also form an annular with the spacing that equates.
Operation principle of the present invention is as follows: during operation knob device 2, finger keeps connected state with the touch sensible parts 21 of metal material.And touch sensible parts 21 match with size, the shape of each touch sensible electrode 3.Because these touch sensible parts 21 are when people's operation knob device 2, be connected with finger, then in the rotary course of knob assembly 2, constantly enter or break away from inductive relationship, thereby change corresponding operating function or running parameter with induction electrode.
In addition, because knob assembly 2 is to be fixed on the glass-ceramic panel 1 with magnetic force, therefore can be with knob assembly 2 from glass-ceramic panel 1 dismounting, dismounting back electromagnetic oven can't operate as normal.Because position corresponding with each touch sensible electrode 3 in operating area 11 is printed on corresponding label symbol, therefore only with hand refers to carry out touch operation in the position of these label symbols, electromagnetic oven just can normally move, and this control mode has been avoided the shortcoming that can't operate because of knob assembly situation such as lose.
Embodiment 2:
The difference of present embodiment and embodiment 1 is that above-mentioned knob assembly 2 is installed in the operating area 11 of panel 1 end face, touch sensible electrode 3 is the traditional spring or the electrode of conductive sponge formula or conductive rubber formula, is directly installed on the circuit board 4 and about in the of 11 corresponding position with operating area.
