The whole machine adopts slender vertical waist-closing shape, soft curved surface weakens the bulkiness of large household appliances, and the main body matte white and black air inlet structure form restrained color contrast. The top of the fuselage is embedded with a floating circular touch screen, and the outer ring surrounds the gradual blue atmosphere lamp. The screen can not only display air data such as PM2.5 and formaldehyde, but also present anthropomorphic expressions, giving the product emotional interactive experience. The back vertical close grille is used as the air inlet channel, with a simple metal decorative plate, giving consideration to ventilation performance and delicate texture. The top surface is designed with undulating heat dissipation texture to transform the heat dissipation function into a flowing visual shape. The overall language is simple and soft, and can be naturally integrated into modern, light luxury and other home scenes.
