Description

Air purifier including a polymer part with a translucent layer One embodiment disclosed in this document relates to an air purifier or home appliance comprising a polymer part including a translucent layer. Generally, various surface treatment technologies can be used to improve the aesthetics and durability of metal surfaces. Surface treatment technologies may include polishing, coating, and etching. Polishing is a method of grinding a metal surface to impart gloss and create a smooth texture. While polishing provides a luxurious appearance, it has limitations in producing unique visual effects such as texture or transparency. Coating (e.g., electrodeposition, painting, or deposition) involves applying various materials to the metal surface to form a protective layer or impart color and texture. However, the thickness and uniformity of the coating layer are limited, and peeling or damage may occur over time. Etching technology is a technique that forms an etching layer on the metal surface using chemical or electrochemical methods. While etching technology can provide natural textures and unique surface patterns, it focuses primarily on forming opaque oxide films, making it difficult to create translucent layers. Surface treatment technologies such as polishing, coating, and etching lack optical versatility, make it difficult to simultaneously achieve appropriate transparency and texture, and struggle to strike a balance between durability and aesthetics; therefore, there is a need for improved surface treatment technologies that provide consumers with aesthetic appeal and beauty while possessing durability.
