  • FIG. 1 is a perspective view of an air conditioning indoor unit 1 while it is not operating.
  • FIG. 2 is a perspective view of the air conditioning indoor unit 1 while it is operating.
  • the air conditioning indoor unit 1 is a wall-mounted type, and a body 20 thereof is equipped with a casing 10, side surface members 24, and a movable panel 31 as members forming the outer enclosure.
  • FIG. 3 is a sectional view of the air conditioning indoor unit 1.
  • the casing 10 forms a substantially rectangular three-dimensional space with a front surface portion 101, an upper surface portion 102, and a lower surface portion 103; a frame 11, an indoor heat exchanger 12, a fan 13, and a filter 21 are housed in that three-dimensional space.
  • an air inlet 18 (see FIGS. 1 and 2 ) comprising plural slits is disposed in the upper surface portion 102.
  • an air outlet 19 (see FIG. 2 ) is disposed from the lower portion of the front surface portion 101 to the front portion of the lower surface portion 103.
  • the indoor heat exchanger 12 and the fan 13 are attached to the frame 11.
  • the indoor heat exchanger 12 performs heat exchange between it and the air passing through it.
  • the fan 13 applies the air taken in from the air inlet 18 to the indoor heat exchanger 12, causes the air to pass through the indoor heat exchanger 12, and blows out the air to the air outlet 19.
  • a horizontal flap (not shown in the drawings) that guides the air that is blown out is disposed in the air outlet 19.
  • the horizontal flap is driven by a motor 171 and not only changes the direction in which the air is blown out but can also open and close the air outlet 19 on the lower surface portion 103 side.
  • the filter 21 is placed between the front surface portion 101 and upper surface portion 102 of the casing 10 and the indoor heat exchanger 12.
  • the filter 21 removes dust and dirt included in the air inflowing toward the indoor heat exchanger 12.
  • the side surface members 24 are attached in such a way as to cover the sides of the casing 10 and are responsible for the outer appearance of the casing 10 as seen from the side.
  • the movable panel 31 creates a distinctive design with a front surface portion 31a that has a flat shape and side surface portions 31b that are formed continuously rearward from both ends of the front surface portion 31a.
  • the front surface portion 31a and the side surface portion 31b are formed integrally.
  • the front surface portion 31a covers the whole of the front surface portion 101 of the casing 10, and the side surface portions 31b cover front halves of the side surface members 24.
  • the front surface portion 31a of the movable panel 31 is responsible for the outer appearance of the front surface of the air conditioning indoor unit 1 and the side surface portions 31b of the movable panel 31 and the side surface members 24 are responsible for the outer appearance of the side surfaces.
  • the movable panel 31 moves to a position away from the front surface portion 101 of the casing 10 and is inclined compared to when the air conditioning indoor unit 1 is not operating. Consequently, the air inlet 18 and the air outlet 19 on the front surface portion 101 side of the casing 10 are opened.
  • the movable panel 31 has a layered structure, with a first panel member 311 in which design considerations are given greater importance being placed on the outer side responsible for the outer appearance and with a second panel member 312 that supports the first panel member 311 being placed on the inner side.
  • FIG. 4 is an exploded perspective view of the movable panel 31.
  • the first panel member 311 is made of aluminum alloy
  • the second panel member 312 is made of ABS resin.
  • the material of the first panel member 311 is not limited to aluminum alloy and may also be another metal such as stainless steel.
  • aluminum alloy is employed as the material of the first panel member 311 because it is light, resistant to corrosion, and suited to long-term use.
  • FIG. 5 is an enlarged sectional view of end portions of the movable panel 31.
  • the first panel member 311 and the second panel member 312 have the same shapes, but end portions on each side of the second panel member 312 curve back in the frontal direction to form grooves 312a. End surfaces of the first panel member 311 fit into these grooves 312a.
  • the first panel member 311 is formed by pressing from a plate material made of metal, so ordinarily an end surface treatment such as chamfering or hemming is performed so that safety and the beauty of the end surfaces are ensured; however, the end surfaces of the first panel member 311 are covered and hidden by the grooves 312a, so they are not noticeable to the eye and are not touchable by hand. Consequently, an end surface treatment is unnecessary.
  • FIG. 6 is an enlarged sectional view of lengthwise direction center end portions of the movable panel 31.
  • the first panel member 311 has claws 311 a that project from the end surfaces.
  • three claws 311a are placed at equally-spaced intervals on each end surface on the upper side and the lower side of the first panel member 311. The length to which the claws 311a project is longer than the thickness of the second panel member 312.
  • Through holes 312b through which the claws 311a are inserted are disposed in the groove 312a of the second panel member 312.
  • the claws 311a project through the through holes 312b in the grooves 312a, so the projecting sections are bent. For this reason, even if an external force acts to pull apart the first panel member 311 from the second panel member 312, the first panel member 311 does not separate from the second panel member 312 and fall because the claws 311a and the through holes 312b interfere.
  • Each of the end surfaces of the first panel member 311 faces a layering direction in which the first panel member 311 and the second panel member 312 are layered, and the direction in which the grooves 312a of the second panel member 312 are recessed also faces the layering direction.
  • the grooves 312a into which the end surfaces of the first movable panel 311 fit are formed in the end portions of the second panel member 312.
  • the end surfaces of the first panel member 311 are covered and hidden by the grooves 312a, so they are not noticeable to the eye and are not touchable by hand.
  • the assembler can convey the pressed first panel member 311 to the assembly process without having to perform an end surface treatment such as chamfering or hemming, so this is economical.
  • the movable panel 31 has a two-layer structure comprising the first panel member 311 and the second panel member 312, but the movable panel 31 is not limited to this and may also employ a structure with three or more layers in which one or more auxiliary panel members are placed between the first panel member 311 and the second panel member 312.
  • the present invention it is not necessary to perform an end surface treatment even in a case where a panel member made of metal is used as the panel member on the side noticeable to the eye, so the present invention has the advantage that manufacturing costs are kept low, and the present invention is useful not only in air conditioning indoor units but also in panels responsible for the outer appearances of devices.
