Definitions

  • the present invention relates to a fixing device and a fixing structure for an air conditioner and, more particularly, to measures for improving fixing strength and workability in fixing the air conditioner.
  • Conventional air conditioners include a wall-mounted type as disclosed in Japanese Examined Patent Publication No. SHO 59-25927 and a ceiling-suspended type as disclosed in Japanese Examined Patent Publication No. SHO 63-15494, of which the wall-mounted air conditioner is designed to be fixed by, e.g., securing a fixing board having a hook provided on an upper portion thereof to a side wall of a room and hanging the air conditioner on the hook of the fixing board.
  • the ceiling-suspended air conditioner is typically designed to be fixed to hanger bolts buried in a ceiling.
  • a casing of the air conditioner is fixed to the ceiling by tightening, from above and below, a plurality of nuts screwed into the hanger bolts with the bolts extending through fixing holes formed in the casing.
  • the fixing structure of the wall-mounted air conditioner in which only the rear face of the casing is fixed by using the fixing board presents a problem in terms of strength.
  • the present invention has been achieved in view of the foregoing. It is therefore a first object of the present invention to enhance fixing strength in a fixing structure for a wall-mounted air conditioner.
  • a second object of the present invention is to provide a fixing structure which is also applicable to a ceiling-suspended air conditioner and thereby improve workability.
  • the present invention fixes an air conditioner (1) by fixing, to a side wall (72) or ceiling (71) of a room, a fixing device (80) with which a lower portion of a rear face (10b) of the air conditioner (1) and a portion of the air conditioner (1) anterior thereto are engaged and then bringing the air conditioner (1) into engagement with the fixing device (80) .
  • first solving means used in the present invention is a fixing device for an air conditioner, the device comprising a vertical plate member (81) extending along a rear face (10b) of an air conditioner (1) and a horizontal plate member (82) extending forwardly from the vertical plate member (81) , the vertical plate member (81) and the horizontal plate member (82) being formed integrally, the vertical plate member (81) comprising first fastening means (83) to be engaged with a lower portion (10f) of the rear face of the air conditioner (1) and the horizontal plate member (82) comprising second fastening means (84) to be engaged with the air conditioner (1) in a position anterior to the first fastening means (83) .
  • the vertical plate member (81) is formed with fixing holes (H3) for fixing the fixing device to a side wall (72) of a room and the horizontal member (82) is formed with fixing holes (H1) for bolts (90, 95) for fixing the air conditioner (1) .
  • the fixing holes (H1) of the horizontal plate member (82) are formed in positions corresponding to the hanger bolts (95) of a ceiling (71) for fixing the air conditioner (1) .
  • the first fastening means is first hooks (83) provided on a lower end portion of the vertical plate member (81) and the second fastening means is second hooks (84) provided on left and right edge portions of the horizontal plate member (82) to be engaged with side edge portions (10g) of the air conditioner (1) , the second hooks (84) being formed of an elastic material and comprising respective base portions (84a) located along the side edge portions (10g) of the air conditioner (1) and respective tip engaging portions (84b) formed to bend inwardly of the side edge portions (10g) of the air conditioner (1) from respective lower ends of the base portions (84a) .
  • the air conditioner (1) comprises a first engaging portion (10f) to be engaged with a first fastening means (83) and a second engaging portion (10g) to be engaged with a second fastening means (84) .
  • the fixing device (80) is fixed first to the side wall (72) or ceiling (71) of the room. Then, the first engaging portion (10f) as the lower portion of the rear face (10b) of the air conditioner (1) is brought into engagement with the first fastening means (83) and the second engaging portion (10g) of the air conditioner (1) anterior to the first engaging portion (10f) is brought into engagement with the second fastening means (84) , whereby the air conditioner (1) is fixed to the fixing device (80) .
  • the fixing device (80) is fixed to the side wall (72) of the room by using the fixing holes (H3) of the vertical plate member (81) , the air conditioner is fastened to the fixing device in the same manner as in the first and fifth solving means, and then the air conditioner (1) is secured to the horizontal plate member (82) of the fixing device (80) by using the bolts (90) .
  • the fastening means (83,84) and the engaging portions (10f,10g) are used to temporarily fasten the air conditioner (1) to the fixing device (80) .
  • the fixing device (80) can be fixed to the hanger bolts (95) through the ceiling (71) . Thereafter, the air conditioner (1) can be secured to the fixing device (80) after it is temporarily fastened thereto in the same manner as in the second solving means.
  • the side edge portions (10g) of the air conditioner (1) can be hung on the tip engaging portions (84b) of the second hooks (84) by raising the front side of the air conditioner (1) after hanging the lower portion (10f) of the rear face (10b) of the air conditioner (1) on the first hooks (83) .
  • the second hooks (84) are widened under pressure by the side edge portions (10g) of the air conditioner (1) passing therebetween and elastically deformed.
  • the second hooks (84) recover the original configurations after the side edge portions (10g) have passed through the tip engaging portions (84b) and come into engagement with the side edge portions (10g) .
  • a predetermined gap is formed between the horizontal plate member (82) of the fixing device (80) and the top face (10a) of the air conditioner (1) when the air conditioner (1) is fastened to the fixing device (80) .
  • This allows the inclination of the air conditioner (1) to be adjusted finely by, e.g, differently tightening the bolts (90) against the front, rear, left, and right sides of the air conditioner (1) in securing the air conditioner (1) to the horizontal plate (82) .
  • the air conditioner (1) is installed in the room by bringing the first engaging portion (10f) on the lower portion of the rear face of the air conditioner (1) and the second engaging portion (10g) of the air conditioner (1) anterior to the first engaging portion (10f) into engagement with the first fastening means (83) and second fastening means (84) of the fixing device (80) fixed to the side wall (72) or ceiling (71) of the room.
  • This provides strong fixation even if the air conditioner (1) is of the type having a large depth and thereby attains the first object.
  • the air conditioner (1) is temporarily fastened to the fixing device (80) and then secured to the horizontal plate member (82) . This provides stronger fixation.
  • the third solving means if the fixing device (80) is fixed to the hanger bolts (95) through the ceiling (71) , the air conditioner (1) can be fastened temporarily to the fixing device (80) and then secured thereto. This obviates the necessity for a worker who supports the air conditioner (1) in tightening the nuts against the hanger bolts (95) .
  • the fixing device (80) is also applicable to the ceiling-suspended air conditioner (1) and fixing workability can be enhanced, whereby the second object is attained.
  • the third solving means also offers the advantage that the air conditioner (1) can be fixed to either of the side wall (72) and ceiling (71) of the room and placement flexibility is enhanced.
  • the air conditioner (10) can be fastened to the fixing device (80) by merely raising the front side of the air conditioner (1) after hanging the lower portion (10f) of the rear face (10b) of the air conditioner (1) on the first hooks (83) , so that fixation is performed easily.
  • the air conditioner (1) having, e.g., a large depth and therefore likely to be inclined forwardly when it is fixed is prevented from being inclined forwardly and can be held in a horizontal position. Even if the ceiling (71) or the side wall (72) is inclined, the inclination of the air conditioner (1) can be adjusted in accordance with the inclination of the ceiling (71) or the side wall (72) .
  • an air conditioner (1) of the present embodiment is installed at a corner portion defined by a ceiling (71) of a room and a side wall (72) of the room.

  • the fixing device (80) is fixed first by sandwiching it between nuts (96) screwed to the hanger bolts (95) through the ceiling (71) from above and below.
  • the fixing device (80) is fixed to the hanger bolts (95)
  • the lower portion (10f) of the rear panel (10b) of the casing (10) is hung on the first hooks (83) and the front end portion of the air conditioner (1) is raised by using the hooked lower portion (10f) as a support, whereby the air conditioner (1) is temporarily fastened to the fixing device (80) , similarly to the case of fixing the air conditioner (1) to the side wall (72) .
  • nuts (97) against the hanger bolts (95) protruding downwardly from the top panel (10a) and attaching the side panels (10e) to the casing (10) the fixation of the air conditioner (1) is completed.
  • the fans (20R, 20L) are driven by the fan motor (25) to rotate and introduce the room air by suction from the air inlet (41) into the casing (10) .
  • the room air introduced by suction into the casing (10) flows through the air passage (45) , passes through the bellmouth (27) , flows into the fans (20R, 20L) , and laterally flows out of the fans (20R, 20L) toward each of the air outlets.
  • the present embodiment achieves the following effects. That is, since the fixing device (80) is used to fix the air conditioner (1) to the side wall (72) of the room and the top side of the casing (10) is fastened to the fixing device (80) , sufficient fixing strength is obtainable even if the air conditioner has a large depth.
  • the air conditioner (1) is fastened temporarily to the fixing device (80) and then secured thereto whether the air conditioner (1) is fixed to the side wall (72) or to the ceiling (71) , the worker who supports the air conditioner (1) in tightening up the nuts (92, 97) is no more required so that only one worker is sufficient to perform the fixing operation, which improves workability.
  • the gap is provided between the arms (82) and the top panel (10a) of the casing (10) when the air conditioner (1) is brought into engagement with the fixing device (80) , the casing (10) is prevented from being inclined forwardly. Even if the ceiling (71) or the sidewall (72) is inclined, e.g., the gap between the air conditioner (1) and the ceiling (71) can be adjusted advantageously.
  • the present invention is also applicable to the air conditioner (1) having a casing configured as a rectangular parallelepiped on the whole.
  • the present invention is not limited to the air conditioner having a casing with a large depth and is also applicable to an air conditioner of the type having a smaller depth.
  • the horizontal panel member (82) is separated into the left and right parts each formed as an arm having an L-shaped cross section in the foregoing embodiment, the configuration thereof is determined appropriately in accordance with the configuration of the casing (10) and need not necessarily be separated into the left and right parts.
  • the fixing device (80) may also be used exclusively for a wall-mounted application. In that case, fixing means other than the bolts (90) may also be used. To fix the fixing device (80) to the side wall (71) of the room, proper fixing means other than bolts may also be used.
  • the air conditioner can also be fixed to the side wall or the like of the room by using only the hooks (83, 84) without using the bolts (90) or the like if the air conditioner is for, e.g., home use and has a smaller depth.
