  • This front panel 26b is formed from a transparent resin, and a painted portion 262 which covers the entire backside of the front panel 26b is provided with a paint layer 27b that is given a color scheme, pattern, and the like.
  • This paint layer 27b is formed by applying paint on the entire backside of the front panel 26b.
  • this front panel 26b is mounted to the front grill 25a via hinges 74. Also, this front panel 26b can open and close by these hinges 74.
  • the method for manufacturing the indoor unit 2 according to the second embodiment is described. Note that the method for manufacturing the indoor unit according to the second embodiment is entirely the same as the method manufacturing the indoor unit according to the first embodiment, excepting manufacturing of the indoor unit casing. Therefore, here, only manufacturing of the indoor unit casing is described.
  • Step S1 of manufacturing the indoor unit casing 23b is, as shown in Figure 13 , constituted by step S20 of manufacturing the front grill 25a, step S21 of manufacturing the bottom frame 24, and step S22 of manufacturing the front panel 26b.
  • step S20 of manufacturing the front grill 25a and step S21 of manufacturing the bottom frame 24 the front grill 25a and the bottom frame 24 are respectively integrally molded from a resin material or respectively assembled from parts molded from a resin material, and then manufactured.
  • Step S22 of manufacturing the front panel 26b is constituted by step S23 of molding the front panel 26b and step S24 of painting.
  • step S23 of molding the front panel 26b the front panel 26b is molded from a transparent resin material, and thus the transparent front panel 26b is manufactured.
  • a resin material such as a transparent ABS, polystyrene, and the like is used as a transparent resin material in this invention.
  • the hinges 74 (for mounting to the front grill 25a) are integrally molded (refer to Figure 12 ). Further, here, on the front side surface of the front panel 26b, portions opposite the hinges 74 are given an embossed grain pattern as shown in Figure 12 .
  • This embossed pattern is obtained by forming a desired embossed grain pattern, in advance, on a metal mold for molding the front panel 26b.
  • step S24 of painting painting is applied on the entire backside of the front panel 26b.
  • the paint layer 27b which is given a color scheme, pattern, and the like is provided in close contact with the painted portion 262 of the backside of the front panel 26b. Note that, instead of painting, printing may be applied on the backside of the front panel 26b.
  • the portions opposite the hinges 74 are given an embossed grain pattern. Because of this, the portions on the front side opposite the hinges 74 can be designed such that it is completely different from the remaining flat portion on the front side. Therefore, if the portions on the front side opposite the hinges 74 can be designed such that they harmonizes with the design of the flat portion, it is possible to obviate the risk that the design of the front panel 26b of the indoor unit 2 may be hampered by the hinges 74.
  • the indoor unit of the air conditioner according to the present invention obviates the risk that the design of the front panel of the indoor unit may be hampered by the mounting portion.
  • the method for manufacturing an indoor unit of an air conditioner according to the present invention it is possible to manufacture an indoor unit having a highly attractive design. As a result, a more attractively designed indoor units than before can be provided to the market.
