Description

Technical Field

[0001] The utility model relates to the field of water purification equipment, in particular to a glass panel for a water purifier. Background Art

[0002] At present, in the field of water purifier panel display, most use plastic materials. After forming a plastic panel using a plastic mold, a film is laminated on its back (the color of the laminated film is the same as the appearance of the product) to ensure the integrity with the machine appearance. At the same time, various function slots need to be opened on the film laminated on the back in each function display area of the plastic panel. As the equipment is used for a longer time, the plastic panel will discolor, and there will be a color difference between the plastic panel and the laminated film, affecting the appearance of the product.

[0003] For high-end water purifiers, glass panels are generally used. The glass panels are in a stable state and the glass will not discolor. The water purifier panels produced by enterprises have function buttons (hot water outlet button, warm water outlet button, child lock button, etc.), status display areas (UV sterilization display area, filter element status display area, hot water volume display area, current water quality display area, logo display area, after-sales service phone number display area, real-time temperature display area, etc.). Originally, the glass panel was also laminated in the same way as the plastic panel. The specific process is as follows: screen-printing and laminating on the back of the glass (no screen-printing and laminating in each function button area), and a layer of black film needs to be attached to each function button area (on the one hand, assisting the lighting display effect; on the other hand, the display lighting intensity is relatively high, reducing the harm to the human eye).

[0004] When the glass panel of the water purifier is assembled with the installation area of the water purifier sheet metal door panel, due to errors in the manufacturing and assembly processes, there will be a deviation in the installation of the display panel, resulting in a slight misalignment in the display function area, thus causing partial occlusion of the function display and a display skew phenomenon in appearance. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the existing technical problems, the purpose of the utility model is to provide a glass panel for a water purifier and its processing method using an LDS laser direct writing lithography machine, effectively solving the problems of misalignment in the display function area caused by assembly errors in the installation area of the glass panel of the water purifier and the water purifier sheet metal door panel, occlusion of the function display, and a display skew phenomenon in appearance.

[0006] In addition, another purpose of the utility model is as follows: serious problems will occur when uniformly processing micropores using an LDS laser direct writing lithography machine, that is, water mark problems will occur in the installation area of the glass panel of the water purifier and the water purifier sheet metal door panel, affecting the appearance quality of the product.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0008] A glass panel for a water purifier, wherein the glass panel is processed with micro-holes by an LDS laser direct writing lithography machine. Micro-hole parameters: the diameter of the micro-hole points is 100 ± 20 um; the micro-holes are distributed at annular intervals, and the row spacing of the micro-holes is 130 ± 20 um; the proportion of the micro-hole surface, i.e., the micro-hole density, is 2.1% - 10.3%; the distribution mode of the micro-holes is four-side transition and middle transition.

[0009] Further, in the four-side transition, no micro-holes are processed at the four perimeters of the glass panel and the installation area of the water purifier. The micro-hole density gradually increases as a whole from the boundary between the four perimeters of the glass panel and the installation area of the water purifier inward; the micro-hole density gradually increases as a whole from the middle of the panel to the periphery; the micro-hole density in the middle of the panel is greater than that at the boundary between the four perimeters of the glass panel and the installation area of the water purifier.

[0010] Further, a wire-drawing texture is processed on the surface of the glass panel, and a paint layer is provided on the surface after wire-drawing.

[0011] Further, the thickness of the wire-drawing texture is 0.01 - 0.03 mm.

[0012] Further, the paint layer includes a bottom layer, a middle layer, and a surface layer, and the thickness of each layer in the paint layer is 0.02 - 0.15 mm.

[0013] Further, the bottom layer of the paint layer is a silver layer, and the middle layer and the surface layer are gray paint layers.

[0014] The advantages of the present utility model are as follows:

[0015] 1. The present utility model effectively solves the problems that the assembly error occurs in the display function area during the assembly of the glass panel of the water purifier and the sheet metal door panel of the water purifier, resulting in misalignment of the function display, occlusion of the function display, and skewed display appearance.

[0016] 2. By designing the non-uniform structure processed by the LDS laser direct writing lithography machine for the micro-holes on the glass panel of the water purifier, the present utility model effectively solves the problem of water marks in the installation area between the glass panel of the water purifier and the sheet metal door panel of the water purifier, ensuring that there are no problems with the appearance of the product during use.
