  • the indoor unit is attached to the wall surface, and then the lower end of the indoor unit is rotated forward to perform the piping work.
  • the piping work includes disposing a refrigerant piping extending from the heat exchanger provided to the indoor unit, and a drain hose for discharging condensed water generated from the heat exchanger, at the lower end of the indoor unit, and wrapping the refrigerant piping with an insulation member, and then wrapping the refrigerant piping and the drain hose with a tape.
  • Embodiments provide an indoor unit of an air conditioner.
  • an indoor unit of an air conditioner including: a main body including a chassis and a front frame coupled to a front portion of the chassis; a base rotatably coupled to a rear surface of the chassis and fixed to a wall surface; a fan in the main body, the fan sucking indoor air; and a heat exchanger configured to heat-exchange the indoor air sucked by the fan with a refrigerant, the indoor unit further including: a holder member rotatably coupled to the chassis and supported against the wall surface, with being rotated from the main body, so that at least one portion of the main body is spaced apart from the wall surface.
  • FIG. 1 is a cross-sectional view illustrating an indoor unit 10 of an air conditioner according to one embodiment.
  • the indoor unit 10 of the air conditioner includes a chassis 11, a main body, a base 12, and a front panel 14.
  • a front surface of the chassis 11 is provided with a flow guide 111 for generating airflow.
  • the main body includes a front frame 13 coupled to a front portion of the chassis 11.
  • An intake grill 131 is provided to an upper surface of the front frame 13.
  • the base 12 is rotatably coupled to a rear surface of the chassis 11 and fixed to a mounting wall surface.
  • the front panel 14 is movably coupled to a front surface of the front frame 13.
  • the indoor unit 10 further includes an inner panel 15, a heat exchanger 19, a fan 20, and a discharge grill 16.
  • the inner panel 15 is linked to a rear 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 to a lower side of the heat exchanger 19 and sucks and discharges 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 covers the discharge hole.
  • the discharge louver 22 is provided to the discharge hole and controls a discharge direction of air, together with the discharge vane 21.
  • the bottom plate 23 covers piping passing through a lower end of the indoor unit 10.
  • the holder member 24 is rotatably coupled to the chassis 11 and supports the piping.
  • the indoor unit 10 further includes a pre-filter 17 and a dust-collecting filter 18.
  • 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 partial perspective view illustrating a portion A of FIG. 1 .
  • the holder member 24 is rotatably coupled to a rear portion of the indoor unit 10.
  • a piping work on the indoor unit 10 is performed in a state where the indoor unit 10 is mounted to the wall surface.
  • the piping connected to the indoor unit 10 or protruding from the indoor unit 10 to the outside, extends laterally along a bottom surface of the indoor unit 10. At an edge of the indoor unit 10, the piping passes through the bottom surface of the indoor unit 10 to the outside.
  • the piping working on the indoor unit 10 may be performed in a state where the lower end of the indoor unit 10 has been rotated from the wall surface to the front side.
  • the holder member 24 is rotatably connected to the rear portion of the indoor unit 10, particularly, to a lower end of the chassis 11.
  • the holder member 24 includes a holder body 241 bent in an L-shape, an elastic end 242 elastically bendable at an end of the holder body 241, a coupling hook 243 protruding from an outer surface of the elastic end 242, and a pressure surface 244 (refer to FIG. 3 ) pressed by a user's finger.
  • the holder body 241 includes a first body 241a and a second body 241b.
  • the first body 241a provides a spacing distance between the main body and the wall surface in a state where the main body has been rotated.
  • the second body 241b is bent from the first body 241a to stably support the main body against the wall surface in the state where the main body has been rotated.
  • the first body 241a is rotatably coupled to the chassis 11, and the second body 241b is removably coupled to the chassis 11.
  • the first body 241a extends in the up-and-down direction of the main body, and the second body 241b extends in the back-and-forth direction of the main body.
  • the first body 241a extends in the back and forth direction, and the second body 241b extends in the up-and-down direction.
  • a coupling rib 112 protrudes from a rear surface of the lower end of the chassis 11 to catch the coupling hook 243.
  • the coupling rib 112 is fitted between the coupling hook 243 and the pressure surface 244 (refer to FIG. 3 ), so that the holder member 24 is fixed to the rear lower portion of the indoor unit 10.
  • FIG. 3 is a cross-sectional view illustrating the rotated indoor unit 10 for a piping work, according to an embodiment.
  • FIG. 4 is a bottom perspective view illustrating the piping exposed through the rotated indoor unit 10 of FIG. 3 .
  • the piping work is performed after raising and rotating the lower end of the indoor unit 10.
  • the base 12 of the indoor unit 10 is fixed to the wall surface, and the lower portion of the indoor unit 10 is rotated about the upper end of the base 12 as a rotation center.
  • the pressure surface 244 of the holder member 24 is pushed rearward to rotate the holder member 24, so that the holder member 24 is in close contact with the wall surface as illustrated in FIG. 3 .
  • a refrigerant piping P and a drain hose H is disposed at the bottom surface of the indoor unit 10 as illustrated in FIG. 4 .
  • an outer surface of the refrigerant piping P is wrapped with a heat insulation cover C.
  • the lower end of the indoor unit 10 is slightly raised, and then the holder member 24 is rotated forward. After that, the coupling hook 243 of the holder member 24 is caught to the coupling rib 112. Then, the holder member 24 supports the refrigerant piping P and the drain hose H to prevent them from sagging downward.
  • the holder member maintains the state where the lower end of the indoor unit is rotated forward from a wall surface.
  • the holder member rotates and closely contacts a wall surface, thereby improving workability.
  • the holder member supports the indoor unit against the wall surface, so that a user is not required to hold the indoor unit during an installing work, thereby increasing the speed of the installing work.
