  • the mounting module body 242 of the motor mounting module 240 of the second embodiment of the present invention includes the locking piece 254 to be locked to the cabinet 120 by the locking member 252. And, the locking boss 270 is provided to the correspondent position of the cabinet 120 to be locked by the locking piece 254.
  • the locking piece 254 is configured to be vertical to the mounting module body 242 to face a front side of the cabinet 120 in case of being assembled to the cabinet 120.
  • a locking piece 256 is provided to the locking piece 254 by perforating the locking piece 254 to be penetrated by the locking member 252.
  • a reinforcement rib 258 is provided to the motor mounting module 240 to prevent the bending or breakage of the locking piece 254 by vertically crossing over each of the mounting module body 242 and the locking piece 254 to connect them together.
  • the locking piece 254 in case that the locking piece 254 is locked to the locking boss 270 by the locking member 252, it is able to restrict the front-to-rear, upper-to-lower or right-to-left movement or rocking of the motor mounting module 240 and no gap is generated from the motor mounting module 240, and more particularly, between the mounting module body 242 and the insertion guide grooves 262 and 263.
  • FIG. 8 is an exploded perspective diagram of an outlet guide member separated from a cabinet in an indoor unit according to a third embodiment of the present invention
  • FIG. 9 is a perspective diagram of the outlet guide member assembled to the cabinet shown in FIG. 8.
  • outlet guide members 240 are detachably provided to outlets 322 formed at left side, right side and lower side of a cabinet 320 to guide flowing directions of air blown from the cabinet 320, respectively.
  • a vane 310 is rotatably provided to an outside of the outlet guide member 340 to selectively open/close the corresponding outlet 322.
  • the outlet guide member 340 includes a plurality of ribs 342 aligned upward to be evenly spaced apart from each other and at least one louver 344 provided between a plurality of the ribs 342 to guide flowing directions of blown air.
  • each louvers 344 is able to arrange three louvers 344 between the two ribs 343. And, it is able to configure each of the louvers 344 to be tilted against the correspondent rib 343 by a prescribed angle (e.g., 90°).
  • a prescribed angle e.g. 90°
  • the above-configured outlet guide member 340 is detachably provided to the corresponding outlet of the cabinet 320 to facilitate its replacement.
  • the outlet guide member 340 in order to detachably fix the outlet guide member 340, it is able to provide a guide groove 345 to one side of the outlet 322 of the cabinet 320 so that at least one of both upper and lower ends of the outlet guide member 340 can be fitted in the guide groove 345.
  • the guide groove 345 is provided to the cabinet 320.
  • a projection is provided to the cabinet 320 and a groove corresponding to the projection can be provided to the outlet guide member 340.
  • the outlet guide member 340 in order that the outlet guide member 340 is detachably assembled to the air outlet 322 provided to the cabinet 320 in a front-to-rear direction, it is assumed that the guide rove 345 is open in the front-to-rear direction and a front side has an open groove shape to enable a separation of the outlet guide member 340.
  • the above-configured guide groove 345 is configured to have a same size of an inserted portion of the outlet guide member 340 to be fitted into the guide groove 345.
  • FIG. 10 is a cross-sectional diagram according to a cutting line X-X in FIG. 9.
  • the outlet guide member 340 is provided between a base panel 302 of the cabinet 320 and an orifice 160 that will be explained later.
  • the rib 342 of the outlet guide member 340 has a size to enable its front and rear ends to come into contact with the cabinet 320 and the orifice 160, respectively.
  • the present invention provides the following effects or advantages.
  • a vane motor is loaded in a motor mounting module and the motor mounting module then slides in a cabinet to be assembled thereto. So, the present invention facilitates the vane motor to be mounted, thereby reducing a working time to enhance productivity.
  • a mounting module body is damaged or broken in installing a vane motor
  • a motor mounting module is replaced only instead of a whole cabinet. So, the present invention facilitates maintenance and repairs.
  • an outlet guide member prepared separate from a cabinet is detachably provided to an air outlet of the cabinet, the outlet guide member that is damaged or broken can be replaced in a simple manner to facilitate defect repair.
