Description

Technical Field

[0001] The utility model relates to household electrical appliances, in particular to a household electrical appliance control mechanism. Background Art

[0002] Many existing household appliances are equipped with touch-type control mechanisms, which generally attach a film layer to the bottom surface of a transparent plastic panel. The structure in which the film is set at the bottom layer will cause some problems. For example, when the bottom light is not close to the plastic part, or when a white appearance effect is to be achieved, the surface light will have a scattered light problem; furthermore, the film is below the transparent injection molded part, and the light passes through the film and then penetrates the transparent plastic part. Since the plastic part has a certain thickness, the pattern on the film will be unclear, and the light will be unfocused, divergent, or haloed. Utility Model Content

[0008] Preferably, a hook is provided at the end of the control panel, and the hook is snap-fitted with the groove wall of the accommodating groove.

[0009] Preferably, the touch panel is an ITO conductive film touch panel.

[0010] Preferably, the control panel is a light-transmitting panel, an LED light bar is provided in the frame, and the lamp beads on the LED light bar face the control panel.

[0011] Preferably, a plurality of through holes are provided at the bottom of the accommodating groove, and the through holes correspond one-to-one to the lamp beads on the LED light strip.

[0012] Preferably, the frame is fixed inside the bottom cover, and the LED light strip is fixed inside the bottom cover.

[0013] In the household appliance control mechanism disclosed by the utility model, the film, the control panel, the adhesive backing and the touch pad are stacked in sequence from top to bottom, the film is attached and fixed to the surface layer of the control panel, the touch pad is attached to the back of the control panel through the adhesive backing, and then assembled based on the clamping fit relationship between the control panel and the frame. Among them, because the film is attached to the control panel, the two can be combined into a whole through the MD laminating process or the silk screen process, which not only ensures that the film is reliably attached to the control panel, but also has a good light transmission effect and a clear pattern display, which is helpful to improve the touch performance of the household appliance.

[0019] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0020] Embodiment 1

[0021] The utility model discloses a household appliance control mechanism, combined with Figure 1 to Figure 2 As shown, it includes a frame 1, a film 2, a control panel 3, an adhesive 4 and a touch pad 5, the film 2 is attached to the surface of the control panel 3, the adhesive 4 is attached between the bottom surface of the control panel 3 and the touch pad 5, and the control panel 3 is fixedly fitted with the frame 1.

[0022] In the above structure, the film 2, the control panel 3, the adhesive backing 4 and the touch pad 5 are stacked in sequence from top to bottom, the film 2 is attached and fixed to the surface of the control panel 3, the touch pad 5 is adhered to the back of the control panel 3 through the adhesive backing 4, and then assembled based on the clamping fit relationship between the control panel 3 and the frame 1. Among them, because the film 2 is attached to the control panel 3, the two can be combined into a whole through the MD lamination process or the silk screen process, which not only ensures that the film 2 is reliably attached to the control panel 3, but also has a good light transmission effect and a clear pattern display, which is helpful to improve the touch performance of household appliances.
