HOME APPLIANCE WITH SELF-CLEANING SURFACE AND METHOD OF ITS PRODUCTION Russian patent published in 2019 - IPC B08B17/06 B23K26/364 

FIELD: household appliances.

SUBSTANCE: invention relates to household appliance with at least one self-cleaning surface. Household appliance (18, 21) with at least one self-cleaning surface (20, 33, 37) provided on base material (16), in which self-cleaning surface (20, 33, 37) comprises multiple double micro-dimensional structures (3). Double micro-dimensional structure (3) is formed by two single micro-dimensional structures, wherein one single micro-dimensional structure has the first geometrical shape, and the other single micro-dimensional structure has the second geometrical shape (2). Single micro-dimensional structure with a second geometrical shape (2) is placed over a single micro-dimensional structure with a first geometric shape. At that, first geometrical shape represents geometrical shape of micro-rod, and second geometrical form represents geometrical shape of micro-cell (2). Height of the micro clamp is 3–5 times higher than the height of the microcell, and the width of the micro clamp is equal to the width of the microcell.

EFFECT: providing a surface with super-hydrophobic properties, which provides improved capacity of the surface of the domestic appliance for self-cleaning, wherein cleaning of the domestic appliance according to the invention can be eliminated or at least performed less frequently and with lower intensity.
