Home appliance including hairline and manufacturing method thereof

Abstract

A home appliance includes a hairline. A manufacturing method for a home appliance including a hairline includes forming at least one plating layer on a base material; processing a transverse hairline on an upper surface of a plating layer by tilting a hairline processing wheel at a predetermined angle, and forming a coating layer on the hairline. A home appliance having corrosion resistance and anti-fingerprint properties is produced while generating a transverse hairline. In addition, it is possible not to perform a separate plating after hairline processing.

1 . A manufacturing method of a home appliance comprising a hairline, the manufacturing method comprises:
 forming at least one plating layer on a base material;   processing a transverse hairline on an upper surface of the plating layer by tilting a hairline processing wheel at a predetermined angle; and   forming a coating layer on the hairline.   
     
     
         2 . The manufacturing method according to  claim 1 , wherein the tilting angle of the hairline processing wheel is 4° to 10°. 
     
     
         3 . The manufacturing method according to  claim 1 , wherein a pressure applied to the plating layer during the hairline processing is 1 to 1.40 A. 
     
     
         4 . The manufacturing method according to  claim 1 , wherein the forming of the plating layer comprises:
 forming a copper plating layer by plating copper (Cu) on the base material, forming a nickel plating layer by plating nickel (Ni) on the copper plating layer and forming a chromium plating layer by plating chromium (Cr) on the nickel plating layer.   
     
     
         5 . The manufacturing method according to  claim 4 , wherein the forming of the plating layer comprises:
 plating the copper plating layer to 5 to 30 μm, plating the nickel plating layer to 5 to 30 μm on an upper surface of the copper plating layer, and plating the chromium plating layer to 0.30 to 0.80 μm on an upper surface of the nickel plating layer.   
     
     
         6 . The manufacturing method according to  claim 4 , wherein the chromium layer is processed to be worn by 0.08 to 0.20 μm during the hairline processing. 
     
     
         7 . The manufacturing method according to  claim 1 , wherein the base material is aluminum (Al). 
     
     
         8 . The manufacturing method according to  claim 1 , wherein the coating layer is coated using one of acrylic, fluorine, and silane-based paints. 
     
     
         9 . The manufacturing method according to  claim 1 , wherein the hairline is formed to form an angle of 87° to 93° with respect to a vertical line. 
     
     
         10 . A home appliance comprising a hairline, the home appliance comprises:
 a copper (Cu) plating layer formed on an aluminum (Al) base material;   a nickel (Ni) plating layer formed on the copper plating layer; and   a chromium (Cr) plating layer formed on the nickel plating layer and having unevenness formed on an upper surface thereof in a transverse direction.   
     
     
         11 . The home appliance according to  claim 10 , wherein the unevenness is formed to form an angle of 87° to 93° with respect to a vertical line. 
     
     
         12 . The home appliance according to  claim 10 , wherein the thickness of the chromium plating layer is 0.15 to 0.5 μm. 
     
     
         13 . The home appliance according to  claim 10 , wherein the thickness of the copper plating layer is 5 to 30 μm, and the thickness of the nickel plating layer is 5 to 30 μm. 
     
     
         14 . The home appliance according to  claim 10 , further comprising:
 a coating layer formed on the chromium plating layer.   
     
     
         15 . The home appliance according to  claim 14 , wherein the coating layer is one of acrylic, fluorine, and silane-based paints.
