  • the inner panel 15 is link-coupled to a back surface of the front panel 14 and rotatably provided to the front frame 13.
  • the heat exchanger 19 is disposed between the front frame 13 and the chassis 11.
  • the fan 20 is provided at a lower side of the heat exchanger 19 to suck and discharge indoor air.
  • the discharge grill 16 supports a lower end of the heat exchanger 19 and includes a discharge hole.
  • the indoor unit 10 further includes a discharge vane 21, a discharge louver 22, a bottom plate 23, and a holder member 24.
  • the discharge vane 21 selectively shields the discharge hole.

  • the pre-filter 17 filters air sucked through the front surface of the front frame 13 and the intake grill 131.
  • the dust-collecting filter 18 is provided between the pre-filter 17 and the heat exchanger 19.
  • FIG. 2 is a perspective view of an indoor unit in which a signal receiver is installed according to an embodiment.
  • a signal receiver 40 according to an embodiment is installed on a bottom surface of the indoor unit 10.
  • the signal receiver 40 protrudes from the bottom surface of the indoor unit 10 in order to improve reception sensitivity.

  • FIGS. 3 and 4 are perspective views of a process in which a signal receiver is installed in an indoor unit according to an embodiment
  • FIG. 5 is a cross-sectional view taken along line I-I' of FIG. 4 .
  • the signal receiver 40 is installed on a bottom surface around an edge of a side of the front frame 13.
  • edges of both sides of the front frame 13 are bent several times to define an upper surface, a front surface, and a bottom surface.
  • a mounting hole 132 in which the signal receiver 40 is inserted is defined in the bottom surface of the front frame 13.
  • a plurality of coupling ribs 133 is disposed apart by a predetermined distance on an inner surface of the mounting hole 132.
  • a stopper 134 extends at an upper side of the bottom surface of the front frame in which the mounting hole is defined. The stopper 134 extends radially from an edge of the mounting hole 132.
  • the stopper 134 is a protrusion for setting a rotation limit when the signal receiver 40 is installed.
  • the signal receiver 40 includes a housing 42, a bracket 41, and a circuit board 43.
  • the housing 42 receives a sensor 44 for receiving a command signal.

  • the circuit board 43 is vertically inserted inside the housing 42.
  • the sensor 44 is attached to a lower end of one surface of the circuit board 43.
  • the bracket 41 and the housing 42 may be injection-molded in one body, or separately provided to couple the bracket 41 to the housing 42.
  • a plurality of coupling protrusions 421 is arranged on an outer surface of the housing 42. The coupling protrusions 421 interfere with the coupling ribs 133 to allow the signal receiver 40 to be fixed to the mounting hole 132.

  • top surfaces of the coupling protrusions 421 have the same height as bottom surfaces of the coupling ribs 133.
  • the signal receiver 40 is rotated in a clockwise direction or a counter-clockwise direction until the bracket 41 is hung on the stopper 134.
  • the top surfaces of the coupling protrusions 421 are hung on the bottom surfaces of the coupling ribs 133 to complete the installation of the signal receiver 40.
  • a separate process of the signal receiver 40 is performed in reverse order of the installation process thereof.
  • the circuit board 43 is detachably coupled to the support rib 422.
  • the circuit board 43 constituting the signal receiver 40 can be vertically disposed inside the housing 42, the sensor 44 can be maximally close to the bottom surface of the housing 42.
  • the circuit board 43 since the circuit board 43 must be horizontally disposed, the sensor 44 was spaced from the bottom surface of the housing 42 to the inside of the indoor unit 40. Therefore, there is a limitation that the reception sensitivity is reduced.
