  • FIG. 6 is a diagram showing that a side cover of FIG. 1 is coupled to a side panel by screws;
  • FIG. 7 is a section view taken along line VII-VII in FIG. 6 .
  • FIG. 1 is a schematic view showing a laundry machine in accordance with one embodiment of the present invention
  • FIG. 2 is a diagram showing that a side cover of FIG. 1 is coupled to a side panel by a hook.
  • the laundry machine in accordance with the present invention includes a front cover 20 forming a front surface of a cabinet, a top cover 30 forming an upper surface thereof and a side cover 90 .
  • the front cover 20 and the side cover 90 have an excellent appearance considering a design. They are respectively formed of stainless steel so as not to be corroded in spite of frequent contact with water. In order to enhance a processability of the covers, a kind of the stainless steel in STS 300 group having a low spring back characteristic is used to form the covers resulting from checking physical properties of several kinds of the stainless steel.
  • the front cover 20 is integrally formed resulting from molding a stainless steel plate.
