  Inside the unit main body 35, an indoor heat exchanger, a fan and a fan motor (not shown) are accommodated. The indoor heat exchanger is illustrated using a refrigerant pipe (liquid pipe) connected to the refrigerant pipe connection port 43 and a refrigerant pipe (gas pipe) connected to the refrigerant pipe connection port 44 shown in FIGS. Not connected to outdoor unit. The indoor heat exchanger in the unit main body 35 cools or heats the air sucked into the unit main body 35 by evaporation or condensation of the refrigerant guided from the outdoor unit. 45A indicates a drain pipe connection port, and 45B indicates a drain discharge port.

  A plurality of the blowout ducts 36 are extended from the unit main body 35, and one end of each of the blowout ducts 36 is fitted to a blowout outlet 47 that is integrally installed on one side plate 38 of the unit main body 35, and the other end. A blow-out chamber 48 is attached. The blowing chamber 48 is installed at an appropriate position on the ceiling board 33. As will be described later, the room air is sucked into the unit body 35 by the rotation of the fan in the unit body 35, and the air heat-exchanged by the indoor heat exchanger is blown out from the blowing chamber 48 to the conditioned room through the blowing duct 36. Is done.

  In the panel specification built-in air conditioner 30 shown in FIGS. 1A and 2, a ceiling panel 49 is fitted in the lower opening of the unit body 35. The ceiling panel 49 includes a suction plate 50 at a central position, and sucks room air through a gap with the suction plate 50 and introduces it into the unit body 35. 1 (B) and FIG. 3 is a side plate 38 of the unit main body 35, which is a side plate (that is, a duct specification built-in) facing the side plate 38 on which the air outlet 47 is installed. A suction opening (not shown) is formed in the back plate 38B) of the type air conditioner 40, and a single suction duct 52 is usually connected to the side plate 38 (back plate 38B) via, for example, a filter box 51. . A suction grill 53 is fitted to one end of the suction duct 52, and the suction grill 53 is installed at an appropriate position on the ceiling plate 33. Indoor air is taken in from the suction grille 53 and sucked into the unit main body 35 through the suction duct 52. The lower opening of the unit main body 35 is closed by a main body lid 77.

  As shown in FIG. 4, the blowing chamber 48 is paired with a blowing grill 55, and a hanging bolt 42 suspended from the ceiling 32 of the building 31 is attached to a hanging metal 48 </ b> A fixed to the side plate of the blowing chamber 48. It is installed behind the ceiling by hooking. The conditioned air sent through the blowout duct 36 flows as shown by arrows in FIG. 5, and is blown out into the conditioned room through the two blowout ports 55 </ b> A of the blowout grill 55.

  As shown in FIG. 6 (A), the blowout chamber 48 is disposed on the inside of the exterior member 81 made of a steel plate formed in a substantially box shape, and inside the exterior member 81, and on the inside thereof, guides the blown air. An air path forming body 83 made of styrene foam in which an air path 83A (FIG. 5) is formed, and a substantially plate-shaped steel plate lid member 85 covering the air path forming body 83 are configured. These are assembled as shown in FIG. 6B, and then the reinforcing plate 87 and the duct connection flange 90 are screwed as shown in FIG. In this configuration, since the blowout chamber 48 is composed of three parts including the exterior member 81, the air passage forming body 83, and the lid member 85, the number of parts is greatly reduced as compared with the conventional one. Man-hours are reduced and manufacturing costs are greatly reduced.

  As shown in FIGS. 5 and 6, the air path forming body 83 is divided into two forming bodies 83B and 83C, and a projection 89 that contacts either the exterior member 81 or the lid member 85 is formed. The protrusions 89 are integrally formed with all of the outermost peripheral edge portions of the respective surfaces of the respective formed bodies 83B and 83C and all of the peripheral edge portions of the air holes 83D of the one formed body 83B. With this configuration, since the contact area between the respective formed bodies 83B and 83C and the exterior material 81 or the lid material 85 is reduced, the respective formed bodies 83B and 83C are largely expanded and contracted due to a sudden temperature change or the like. Even if it does, the generation | occurrence | production of the dew condensation to the exterior material 81 or the lid | cover material 85 will be suppressed while the generation | occurrence | production of the squeak noise is suppressed, and the wraparound of the air which leaked from the mating surface of each formation body 83B, 83C is blocked | prevented. Is suppressed.

  In addition, an air hole 83D communicating with the blowout duct 36 is opened in one of the air passage forming bodies 83B, and an air volume adjusting plate 93 is disposed in the lid member 85 at a position corresponding to the air hole 83D. ing. The air volume adjusting plate 93 is formed by a remaining portion of the lid member 85 cut out by a substantially arc-shaped notch 93A and a substantially linear notch 93B. The air volume adjusting plate 93 is a pair of connecting portions 93C. It is connected to the lid member 85 via the via.

  In this case, the air volume is adjusted by bending the air volume adjusting plate 93 around the pair of connecting portions 93C in the direction of the arrow X so as to be pushed into the air holes 83D of the air path forming body 83B. If the air volume adjusting plate 93 is largely bent, the air volume increases, and conversely, if the bending amount is reduced, the air volume decreases. In this configuration, since the air volume adjusting plate 93 is formed by the remaining portion of the lid member 85 cut out by the substantially arc-shaped cutout 93A and the substantially linear cutout 93B, an extra member is required. Therefore, the air volume adjusting plate 93 can be easily formed. A blowout opening 86 is opened below the air passage forming body 83, and the blowout opening 86 is closed by the blowout grill 55.

  As shown in FIGS. 7 and 8, the blow-out grill 55 includes a resin decorative panel 60, a styrene foam heat insulator 61 disposed on the decorative panel 60, and a louver 62. The decorative panel 60 is provided with two air outlets 55A substantially parallel to the longitudinal direction of the panel, and a wall surface panel 63 constituting a wall surface of the two air outlets 55A is formed integrally with the two air outlets 55A. A central frame 64 extending in the longitudinal direction of the panel is provided. The heat insulator 61 is formed by integrally molding a first heat insulator 65 that is stacked on the wall surface panel 63 and a second heat insulator 66 that is stacked on the central frame 64. The louver 62 is pivotally supported at both ends so as to be rotatable in each blowing air passage, and is used for adjusting the blowing direction of the conditioned air blown out from each blowing outlet 55A.

  In this configuration, the second heat insulator 66 extends in the longitudinal direction of the central frame 64 and is formed in an upward convex cross-sectional shape (substantially triangular cross-sectional shape in the present embodiment). In addition to functioning as a blowout air passage partition body, it is possible to function as a blowout air passage partition body that partitions each blowout air passage.

By the way, in the said structure, there exists a possibility that the blowing air quantity which blows off from two blower outlets 55A may not become equal.
In this configuration, as shown in FIG. 5, in the other formation body 83C of the air passage formation body 83, a wind guide surface 83E is formed on the inner wall surface (opposite surface) facing the air hole 83D. The surface 83E has substantially the same position as the extended line L0 of the substantially central point of the air hole 83D, that is, the amount of protrusion gradually increases from the position 83G toward the blowing opening 86, and the lowermost point of the air hole 83D is extended. It is formed so as to be the highest at a position slightly closer to the blowout opening 86 side from the line L, that is, at a position 83F. That is, the guide surface 83E is formed at a position where the blown air supplied through the air hole 83D collides, and is formed to have an inclination that the amount of protrusion increases as it approaches the blowout duct 36.

  In this configuration, the guide surface 83E is inclined so that the upper end 66A of the second heat insulator 66 is positioned on the extension line M of the surface. In this case, the air blown from the blowout duct 36 collides with the inner wall surface including the guide surface 83E of the forming body 83C, and is guided in the direction toward the upper end 66A of the second heat insulating body 66 by the guide surface 83E. Thereby, the blown air is branched by the second heat insulator 66, and the amount of blown air from the two outlets 55A can be adjusted uniformly.

  Moreover, in this structure, since the air path formation body 83C in which this guide surface 83E is formed is made of a polystyrene foam, compared with what forms a wind guide surface by bonding various heat insulating materials etc. like the past. In addition to reducing the number of parts, it is also possible to integrally mold the profile very accurately and easily.

  Each of the above configurations can be applied to both a panel specification built-in air conditioner and a duct specification built-in air conditioner. In the above embodiment, the guide surface 83E is formed on the inner wall surface of the air passage forming body 83C. However, the guide surface 83F may be formed of a panel-shaped heat insulator or the like.
