Definitions

  • a method for manufacturing a front sheet of a microwave oven comprises a first process including a chemical polishing process of removing foreign materials from and polishing a surface of an aluminum sheet so as to give a constant luster thereto, a process of forming a porous anodic oxide film onto the surface of the aluminum sheet, a process of dipping the aluminum sheet into a dye solution containing a dye and of penetrating the dye into a porous film of the anodic oxide film, and a process of sealing the porous film into which the dye has been penetrated.
  • Further processes for removing foreign materials from the surface of the aluminum sheet for example, the process for cleaning up the surface after removing the foreign materials from the surfaces by means of an alkali such as sodium hydroxide, etc. may be included between the steps 108 and 110.
  • a washing process is again performed in a step 112.
  • acid treatment for the surface of the aluminum sheet is performed in a step 114.
  • the acid treatment process is a process for perfectly removing impurities contained on the surface of the aluminum sheet.
  • the aluminum sheet cannot have a pure surface since white spots may be created thereon due to various impurities contained therein. Therefore; the treatment to be described below can be more perfectly performed by completely removing the impurities adhered to the surface of the aluminum sheet.
  • the front sheet 7 of the present invention is installed to wrap around at least a portion of the front, lateral, upper and lower sides of the door panel 1.
  • edge portions where the front side joins with the lateral side and the upper and lower sides, respectively, are treated to have predetermined rounded shapes.
