Problems solved by technology

In order to ensure the brightness of the development, the distance between the LED and the panel must be very small. Because the light is close to the panel, the range of light divergence is small, the middle part of the button icon is very bright, and the rest of the part is dark. uniform

Embodiment 1

[0023] figure 1 It is a schematic cross-sectional structure diagram of the touch button of the electromagnetic oven of the present invention, figure 2 It is a structural schematic diagram of the PCB board in the touch button of the electromagnetic oven of the present invention, as Figure 1-2 As shown, the touch buttons of the induction cooker include: a panel 1, a PCB board 5, a spring button 51 arranged on the PCB board 5, and an LED 52 located at the center of the spring button 51. The spring button 51 is a hollow cylindrical button, or it can be other The shape of the button is, for example, hollow conical or hollow round platform. The number of spring buttons 51 and the LED52 located in the center of the spring button 51 depends on the number of function items of the induction cooker. The diameter of the spring button 51 can be between Φ16mm-Φ24mm , the inner diameter of the area occupied by the button icon is smaller than the inner diameter of the spring button 51, tha...

Abstract

The invention provides a touch key of an induction cooker. The touch key comprises a panel (1), a PCB (5), spring keys (51) arranged on the PCB (5) and LEDs (52) located in the centers of the spring keys (51), and further comprises a diffusion film (4) and a panel label (3) pasted onto the diffusion film (4), wherein the diffusion film (4) is arranged between the upper surfaces of the LEDs (52) and the panel (1); key icons are arranged in the positions, right facing the upper parts of the LEDs (52), of the panel labels by means of silk screening; and the position that corresponds to the panellabel (3) of the panel (1) is pervious to light. According to the touch key of the induction cooker, not only the developing brightness but also the developing uniformity and diffusivity of the touchkey can be guaranteed.

Description

technical field [0001] The invention relates to an electromagnetic cooker, in particular to a touch button of the electromagnetic cooker. Background technique [0002] In the prior art, the touch buttons of an induction cooker generally use a PCB board, on which a spring button (sensing button) and an LED located at the center of the spring button are arranged, and the button is screen-printed on the upper surface of the panel facing the spring button. Icons and panels are generally transparent boards, and the frame of the button icon on the transparent board is the light-transmitting part. When the induction cooker is working, the light emitted by the LED shows the effect of the button icon through the transparent frame of the button icon on the panel. In order to ensure the brightness of the development, the distance between the LED and the panel must be very small. Since the light is close to the panel, the range of light divergence is small, the middle part of the butto...
