Definitions

  • the present invention relates to an indoor unit for an air conditioner.
  • a conventional indoor unit for an air conditioner includes a heat exchanger disposed in a casing, the heat exchanger having a U shape in plan view (see, for example, JP 2015-81692 A ).
  • the heat exchanger includes a first heat exchange part and a second heat exchange part that extend in parallel to the first heat exchange part.
  • the first and second heat exchange parts have distal ends each facing one of four walls of the casing.
  • a distance between the wall and the distal end of the first heat exchange part is equal to a distance between the wall and the distal end of the second heat exchange part.
  • the wall extends in a direction perpendicular to the direction in which the first and second heat exchange parts extend, such that the distance between the wall and each of the distal ends of the first and second heat exchange parts is fixed.
  • EP 0985889 A2 discloses a ceiling embedded type indoor unit which is reduced in height to provide a compact unit body size and which provides a large cooling/heating capability
  • EP2378217 discloses an indoor unit of an air conditioner upon which the preamble of appending claim 1 is based.
  • the present invention provides an indoor unit for an air conditioner, the indoor unit being capable of achieving reduction in size of a casing.
  • the present invention provides an indoor unit for an air conditioner, the indoor unit including:
  • the first extension part in the heat exchanger extends beyond a distal end of the second extension part in the heat exchanger toward the second wall of the casing. Therefore, the distal end of the second extension part in the heat exchanger is closer to the first wall of the casing than the distal end of the first extension part in the heat exchanger is. Accordingly, for example, a portion of the second wall in the casing, the portion being located near the second extension part, is allowed to be recessed toward the first wall of the casing. In addition, for example, a portion of the fourth wall in the casing, the portion being located near the distal end of the second extension part, is recessed toward the third wall of the casing. This configuration thus enables reduction in size of the casing.
  • the indoor unit for an air conditioner further includes: a drain pump disposed between a portion of the second wall in the casing, the portion being located near the first extension part, and the distal end of the first extension part in the heat exchanger.
  • the drain pump is disposed between the portion of the second wall in the casing, the portion being located near the first extension part, and the distal end of the first extension part in the heat exchanger, which is allowed to eliminate a necessity to dispose the drain pump outside the casing.
  • This configuration therefore reduces increase in required space around the casing.
  • the indoor unit for an air conditioner further includes: a refrigerant pipe connection part connected to a refrigerant pipe and disposed on a portion of the second wall in the casing, the portion being located near the second extension part.
  • the portion of the second wall in the casing, the portion being located near the second extension part is allowed to be recessed toward the first wall of the casing. Therefore, the refrigerant pipe connection part does not largely protrude outward (i.e., oppositely to the first wall) from the remaining portion of the second wall in the casing in such a manner that the refrigerant pipe connection part connected to the refrigerant pipe is disposed on the portion of the second wall in the casing, the portion being located near the second extension part.
  • the indoor unit for an air conditioner further includes: a refrigerant pipe connection part connected to a refrigerant pipe and disposed on a portion of the fourth wall in the casing, the portion being located near the distal end of the second extension part.
  • the portion of the fourth wall in the casing is allowed to be recessed toward the third wall of the casing. Therefore, the refrigerant pipe connection part does not largely protrude outward (i.e., oppositely to the third wall) from the remaining portion of the fourth wall in the casing in such a manner that the refrigerant pipe connection part connected to the refrigerant pipe is disposed on the portion of the fourth wall in the casing, the portion being located near the distal end of the second extension part.
  • the partition is connected to the distal end of the first extension part in the heat exchanger and the distal end of the second extension part in the heat exchanger to cause air from the centrifugal fan to flow toward the first and second extension parts, which is allowed to improve efficiency of heat exchange between the air from the centrifugal fan and the first and second extension parts.
  • the present invention provides an indoor unit for an air conditioner, the indoor unit being capable of achieving reduction in size of a casing.
  • FIG. 1 is a perspective view of an indoor unit for an air conditioner according to a first embodiment of the present invention, the indoor unit being seen obliquely from below.
  • FIG. 2 is a perspective view of the indoor unit seen obliquely from above.
  • the indoor unit according to the first embodiment is designed to be embedded in a ceiling, and includes a casing main body 1, a panel 2 having a quadrilateral shape, the panel 2 being mounted to a lower side of the casing main body 1, and a grille 3 detachably mounted to the panel 2.
  • the casing main body 1, the panel 2, and the grille 3 constitute an example of a casing.
  • the indoor unit also includes a pipe connection part 5, a pipe connection part 6, and a drain socket 7 each protruding from a sidewall of the casing main body 1.
  • each of the pipe connection parts 5 and 6 is connected to an external refrigerant pipe (not illustrated).
  • the drain socket 7 is connected to an external drain hose (not illustrated).
  • the indoor unit also includes an electrical component 8 disposed on the sidewall of the casing main body 1 and juxtaposed with the pipe connection parts 5 and 6 and the drain socket 7.
  • the panel 2 has a blow-out port 10.
  • the blow-out port 10 is located on one of longitudinally opposite sides of the grille 3 so as to extend along a shorter side of an outer edge of the panel 2.
  • the panel 2 also has a flap 20 pivotably mounted thereto and configured to open and close the blow-out port 10. In FIG. 1 , the flap 20 closes the blow-out port 10.
  • the indoor unit according to the first embodiment also includes hanger fittings 101, 102, 103, and 104 (the hanger fitting 104 is illustrated in FIG. 5 ).
  • the hanger fittings 101, 102, 103, and 104 are secured to hanger bolts (not illustrated) suspended from, for example, a framework in a roof-space. The indoor unit is thus suspended from a ceiling.

  • the flap 20 has a U shape as seen from below with the blow-out port 10 closed by the flap 20.
  • the casing main body 1 (see FIGS. 1 and 2 ) has in its center a suction port 1a.
  • a filter 4 (see FIG. 4 ) is disposed between the suction port 1a and the grille 3.
  • FIG. 4 is a sectional view taken along line IV-IV in FIG. 3 .
  • the same constituent elements as those illustrated in FIGS. 1 to 3 are denoted with the same reference signs as those for the constituent elements illustrated in FIGS. 1 to 3 .
  • the casing main body 1 houses therein a turbo fan 30.
  • the turbo fan 30 is driven by a motor 31 to rotate in a predetermined rotation direction.
  • the predetermined rotation direction corresponds to a counterclockwise direction when the turbo fan 30 is seen from below.

  • the turbo fan 30 sucks in indoor air via a space inside the bell mouth 32.
  • the casing main body 1 also houses therein a heat exchanger 40 and a partition plate 50 at a position around the turbo fan 30. Air from the turbo fan 30 flows toward the blow-out port 10 via the heat exchanger 40. At this time, the partition plate 50 guides to the heat exchanger 40 the air from the turbo fan 30.
  • the partition plate 50 is an example of a partition. The partition may constitute a part of the casing main body 1.
  • the casing main body 1 also houses therein a drain pan 60 at a position below the heat exchanger 40 and partition plate 50.
