Description

Technical Field

[0001] The utility model relates to the technical field of spray shielding, in particular to an auxiliary device for surface spray shielding of a main control board for a washing machine. Background Technique

[0002] The control of existing intelligent washing machines mostly uses a main control board. Knobs are usually installed on the main control board of the washing machine, and different washing modes can be selected through the knobs. Fonts are sprayed on the outer surface of the washing machine main control board along the side of the knobs to indicate the washing modes corresponding to the knobs. The spraying method used for spraying the fonts beside the knobs is spray shielding, and spray shielding technology is applied in various industries.

[0003] Chinese Patent No. CN202222633339.8 discloses a spray shielding for a TV back panel, which specifically includes a shielding plate. The shape of the shielding plate corresponds to the shape of the spray shielding area of the TV back panel. The shielding plate is a flexible metal plate. One side of the lower end of the shielding plate is provided with a strip-shaped block. Inside the strip-shaped block, two strip-shaped cavities are symmetrically arranged along the length direction of the strip-shaped block. The strip-shaped cavities are arranged along the length direction of the strip-shaped block and penetrate through both ends of the strip-shaped block. An L-shaped rod is accommodated in the strip-shaped cavity, and a compression spring is arranged inside the strip-shaped cavity. When this back panel spray shielding is used, through the elastic action of the compression spring, the L-shaped rod is pulled to clamp and fix the shielding plate on the TV back panel. At the same time, through the clamping of the edge of the back panel by the clamping plate and the fastening action of the elastic rubber pad, the fixing effect of the shielding plate on the back panel and the stability during spraying are improved, and the possibility of the shielding plate shaking during spraying is reduced.

[0004] The above patent provides a spray shielding device, but this structure of the spray shielding device is not suitable for spray shielding the fonts on the main control board of a washing machine. Currently, spray shielding of the fonts on the main control board of a washing machine mostly uses pre-prepared spray shielding stickers pasted on the main control board and then spraying is carried out. However, in the actual operation process, often due to the misalignment of the position of the spray shielding stickers, the position of the sprayed fonts is inclined, which cannot correspond to the position where the knob rotates, and thus repeated spray shielding is required, affecting the spraying efficiency of the washing machine main control board. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an auxiliary device for surface spray shielding of a main control board for a washing machine, aiming to improve the problem that the existing spray shielding method for the main control board of a washing machine is prone to misalignment of the position of the spray shielding stickers, resulting in the inclination of the position of the sprayed fonts, which cannot correspond to the position where the knob rotates, and repeated spray shielding is required, affecting the spraying efficiency of the washing machine main control board.
