Abstract
The utility model relates to an invisible switch applied on the panel of household electric appliance. The switch comprises an indicator, an inductor, a control wiring board and a guidance panel. The guidance panel is surmounted over the control wiring board, the indicator is arranged between the control wiring board and guidance panel and linked to control wiring board by electric connection, the inductor is linked to control wiring board by electric connection and arranged on the medial surface of the guidance panel and located above the indicator; the guidance panel is made of translucent or transparent material; the inductor is an inducting chip on which an aperture is preformed above the indicator; a spring is arranged between the control wiring board and the guidance panel, the spring sleeve is arranged above the indicator and one end of the sleeve is put against the control wiring board and the other end pushes the inducting chip against the medial surface of the guidance panel. The utility model has the following merits: when the invisible switch is idle, the guidance panel does not display any design or text, nor indicates the position of the switch. Therefore, the guidance panel is very tidy and smooth, the structure is simple and the whole product is economic and practical.
Description
Technical field
The utility model relates to household appliance technical field, particularly a kind of stealthy switch that is used for the household electrical appliance panel.
Background technology
The existing switch that is used for the household electrical appliance panel, a kind of is the button touch-switch, as the patent No. is 01254756.5, " a kind of luminous the Show Button switch " disclosed, it comprises switch body and is overlying on its surperficial push button panel, in switch body, be provided with the light-emitting component with the synchronous break-make of switch, it is characterized in that described push button panel central authorities are opaque position, and periphery be transparent position.Described push button panel can be made of center panel that is transparent material and the peripheral panel that is centered around its periphery, wherein center panel is analysed and observe and is ", its central protuberance is coated with the button cap of transparent materials, and peripheral panel then is pressed on the low recessed position of its periphery.Though it is more convenient that this kind switch uses, following shortcoming is always arranged: it makes operation planar totally smooth inadequately, and the printed patterns of the function of switch and position indication has been upset whole effect.
Another kind is the touch sensible switch, as the patent No. is 91228701.2, a kind of " multi-functional soft-touch control " disclosed, it is by housing, sensing chip and electronic circuit board are formed, electronic circuit board is provided with touch detection circuit, differential circuit, trigger, the 2S testing circuit, the memory delay circuit, switch execution and power circuit and function conversion circuit, the output that it is characterized in that touch detection circuit respectively with differential circuit, the 2S testing circuit, function conversion circuit is connected, differential circuit matches with trigger, the output signal of trigger is connected to switch and carries out and power circuit, the output of 2S testing circuit joins with the memory delay circuit, the memory delay circuit also carries out with trigger and switch and power circuit matches, function conversion circuit is trigger also, the 2S testing circuit is connected, on switch execution and power circuit, be connected to two lead-in wires, one is civil power live wire inlet wire, and another root is a civil power live wire loop line.Though this kind switch has solved the problems referred to above, its circuit complexity, the induction display panel is bigger, very uneconomical.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of operation planar that can make totally smooth at above-mentioned prior art present situation, simple in structure, the economical and practical again stealthy switch that is used for the household electrical appliance panel.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of stealthy switch that is used for the household electrical appliance panel is characterized in that: it comprises indicator light, inductor, control circuit board and guidance panel; Described guidance panel is covered in described control circuit board top; Described indicator light is arranged between described control circuit board and the guidance panel, and is electrically connected on the control circuit board; Described inductor is arranged at described guidance panel medial surface and is positioned at the top of described indicator light, and inductor is electrically connected with control circuit board.
Described guidance panel is translucent material or transparent material; Described inductor be one be positioned at described indicator light directly over and have the sensing chip in a hole on it; Also be provided with a spring between described control circuit board and guidance panel, described spring housing is located on the described indicator light, and the one end is butted on the control circuit board, and the other end is butted on described sensing chip on the described guidance panel medial surface; And described spring makes described control circuit board and described sensing chip conduct.
Compared with prior art, advantage of the present utility model is, when product did not use, no any pattern and literal on guidance panel do not have the position at indicator cock place yet, make guidance panel totally smooth, and be simple in structure again, economical and practical.
