As shown in FIG. 10, the decorative panel 120 has a ceiling hole 1 05 when the unit main body 110 is inserted into the ceiling 104. A suction port 121 is formed along one side edge in the longitudinal direction of the decorative panel 120 so as to suck in the air in the conditioned room, and along the other side edge. An air outlet 122 is formed.

[0024] A suction grille 124 that supports the filter 123 is detachably disposed at the suction port 121 of the decorative panel 120, and extends in the width direction of the decorative panel 120 at the outlet 122 of the decorative panel 120. A flap 125 is arranged. The flap 125 is supported so as to be rotatable about a shaft 126 by driving a motor (not shown). Further, as shown in FIG. 9, the decorative panel 120 includes a detachable side panel 127 at a position facing the hanging bracket 112 of the casing 111. When the side panel 127 is removed, the hanging bracket 112 is exposed. The operator can adjust the height of the unit body 110 from the room!

[0025] As shown in FIGS. 10 and 11, the unit main body 110 is provided with a partition plate 132 that partitions the internal space of the casing 111 into a machine chamber 130 and a heat exchange chamber 131. A blower 102 and an electrical equipment box 106 are arranged, and a heat exchanger 103 and a refrigerant pipe 107 connected to the heat exchanger 103 are arranged in the heat exchange chamber 131. The refrigerant pipe 107 constitutes a part of a refrigerant feed pipe that sends refrigerant supplied from an outdoor unit (not shown) to the heat exchanger 103 and a refrigerant return pipe that returns the refrigerant circulated through the heat exchanger 103 to the outdoor unit. is doing.

The blower 102 includes two fan units 136 that house the multi-blade fan 135 and a motor 137 that rotationally drives the multi-blade fan 135 of each fan unit 136 and is housed in the electrical box 106. The motor 137 is driven based on the drive signal from the control board, and as shown in FIG. 10, the air in the conditioned room is sucked through the suction port 121 of the decorative panel 120, and the filter 123 The indoor air purified by the above is blown toward the heat exchange chamber 131.

[0027] The heat exchange 103 is a fin-and-tube type heat exchange, and is arranged obliquely (inclined arrangement) in the heat exchange chamber 131 that secures a large heat exchange area. Under this heat exchange 103, a drain pan 138 made of polystyrene foam is installed to prevent the condensed water from the heat exchanger 103 from leaking into the conditioned room, and the drain pan 138 insulates the heat exchange chamber 131. Also serves as part of the material. In addition to the drain pan 138, the heat exchange chamber 131 is insulated by a foamed polystyrene heat insulating material 140 disposed along the inner wall surface of the casing 111.

[0028] With the above configuration, in this air conditioner 100, the indoor air in the conditioned room is blown from the suction port 121 of the decorative panel 120 through the filter 123 by the blower 102, as indicated by arrows in FIG. After being sucked into the unit body 110, blown out toward the heat exchanger ^ 103, exchanged heat with the heat exchanger ^ 103, and then collided with the inner wall surface 110A of the unit body 110 in a direction almost perpendicular to it. The direction is changed and blown out from the outlet 122 of the decorative panel 120. As a result, the room air circulates through the heat exchanger 103 in the unit body 110, and the room temperature can be adjusted (indoor air conditioning).

By the way, in this air conditioner 100, a blowout duct 150 (FIG. 13) is selectively connected to the side wall 111X of the casing 111 of the unit main body 110 according to a user's request or the like. Thus, the conditioned air heat-exchanged by the heat exchanger 103 can be blown out into the conditioned room. In this embodiment, as shown in FIG. 12, the side wall 11 1 IX to which the blowout duct 150 is connected is knocked out on the outer wall surface (scheduled connection surface) 111A of the blowout duct 150 along the edge of the planned duct opening D. Holes 160 are formed at intervals, and by cutting the members between the knockout holes 160 so as to connect the knockout holes 160, the duct opening DO (FIGS. 14 and 15) of the blowout duct 150 can be easily formed. Become! /

More specifically, in the present embodiment, as the planned duct opening D, as shown in FIG. 12, four planned vertical duct openings D1 to D4 in two vertical rows and two horizontal rows are assumed. Narrow-out knockout holes 160 are formed at intervals along the edges of the respective duct planned openings D1 to D4. Here, for the planned duct openings D1 and D2, the knockout hole 160 along the lower edge of the upper duct opening D1 extends along the upper edge of the lower duct opening D2. As a result, the number of knockout holes 160 can be reduced compared to the case where the knockout holes 160 are formed so that the planned duct openings D1 and D2 are separated from each other. The processing time of knockout hole 160 can be reduced.

[0031] Also, for the planned duct openings D3 and D4 arranged vertically, the knockout hole 160 along the edge of one planned duct opening D3 is connected to the other planned duct openings D4 in the same way as the planned duct openings D1 and D2. The knockout hole 160 along the edge is also used, and the work of processing the knockout hole 160 is reduced. In addition, as described above, the heat insulating material 140 is disposed inside the knockout holes 160, so that this heat insulating material 140 prevents outside air from entering the unit main body 110 via the knockout holes 160. Thus, the heat insulation in the unit body 110 is maintained.

FIG. 13 is a perspective view showing an example of the blowout duct 150. The blowout duct 150 includes a metal cylinder 151 connected to the unit body 110 of the air conditioner 100, and a metal cylinder 152 communicated with an opening (blowout duct air outlet) provided in the ceiling or the like. The cylinders 151 and 152 are connected to each other, and are roughly constituted by a connection body 153 formed of a flexible material. With this connection body 153, the direction of one cylinder 153 is arbitrarily set with respect to the other cylinder 152. The direction can be changed. A flange 154 extending inward is provided in the opening 151A of the cylindrical body 151. A plurality of pin holes 155 are provided in the flange 154, and the hooking member 156 is spaced apart. Connected with pins. The hook member 156 is formed by bending a metal plate member into a substantially U-shape, and this U-shaped portion is formed so as to be hooked on the work body 110. The hook member 156 is configured such that the U-shaped portion is hooked on the unit main body 110 so that the opening 151A side of the blowing duct 150 can be temporarily supported at the mounting position of the unit main body 110.

FIG. 14 and FIG. 15 are partial cross-sectional views showing a state where the blowout duct 150 is connected to the unit main body 110 of the air conditioner 100. As shown in these figures, when connecting the outlet duct 150 to the unit body 110, one or more of the planned duct ports D1 to D4 of the unit body 110 are opened as duct ports DO, and After blocking the duct opening DO, cutting a part of the heat insulating material 140 to allow the duct opening DO and the heat exchange chamber 131 to communicate with each other, further, on the planned connection surface 111A of the mute body 110, Female in the position corresponding to pin hole 55 of outlet duct 150 By forming a screw hole and pinning the blowout duct 150 to the female screw hole via the pin hole 155, the blowout duct 150 is connected to the unit main body 110. In this case, when the planned duct opening D1 is used as the duct opening DO in order to equalize the left and right air flow, the duct duct D3 is also preferably used as the duct opening DO. If the planned opening D2 is the duct opening DO, the duct opening D4 is also preferably the duct opening DO.

[0034] As described above, when connecting the blowout duct 150 to the unit main body 110, the hook member 156 of the blowout dust 150 is pulled out to insulate the lower edge DOL of the duct opening DO of the unit main body 110. By hooking through the cushioning material 157, the duct opening side of the blowout duct 150 is brought into a buoyant state, and in this state, the blowout duct 150 is aligned and pin-connected. For this reason, if the duct opening side of the blowout duct 150 is lifted once, the hooking member 156 can temporarily hold the datatro side in a buoyant state, and the connection work of the blowout duct 150 can be facilitated. it can. The heat insulating cushion material 157 is formed of a heat insulating material having a cushioning property that fills the gap between the blowout duct 150 and the unit main body 110, and is formed of, for example, a polyethylene material. By inserting this heat insulation cushioning material 157 between the blowout duct 150 and the unit main body 110, the gap between the blowout duct 150 and the unit main body 110 is completely blocked and sufficient heat insulation measures are taken. Is done.

[0035] As shown in FIG. 14, when only the duct scheduled ports D2 and D4 of the unit main body 110 are used as the duct port DO, the amount of air supplied to the blowing duct 150 can be reduced, so that the blowing duct 150 and the decorative panel 120 can be reduced. The distribution ratio of conditioned air supplied to the air outlet 122 can be increased on the air outlet 122 side.

On the other hand, as shown in Fig. 15, if all the planned duct openings D1 to D4 of the unit main body 110 are set as the duct opening DO, the opening area of the duct opening DO can be made larger than the case of Fig. 14, and therefore the supply to the outlet duct 150 Therefore, the distribution ratio of the conditioned air supplied to the outlet duct 150 and the outlet 122 of the decorative panel 120 can be increased on the outlet duct 150 side.

[0036] In the present embodiment, knockout holes 160 along the edges of the plurality of planned duct openings D1 to D4 are previously formed in the casing 111 at intervals, and the planned duct openings D1 to D4 are selected. Since the duct opening DO is selectively opened, the supply air volume to the outlet duct 150 can be adjusted, The distribution ratio of the conditioned air supplied to the blowout duct 150 and the blowout port 122 of the decorative panel 120 can be adjusted in various ways.

In addition, when forming the duct opening DO, it is only necessary to selectively cut between the knockout holes 160 formed in the casing 111, so that the conventional one having a disk for adjusting the air volume to the blowout duct is used. In comparison, the air volume to the blowout duct can be easily adjusted without increasing the number of parts, and retrofitting of the blowout duct is easy. Note that the air conditioner 100 can be configured such that when the blowout dust 150 is connected, the blowout port 122 of the decorative panel 120 is closed with a predetermined closing member, and the blowout duct 150 alone blows out the conditioned air. is there.

The embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made. For example, in the first embodiment, the force screw described in the case where the pocket portion 99 is configured as a sealed housing portion for housing the portion exposed on the side panel 19A side of the screw 80B, which is a fixing member, in a substantially sealed state. It is also possible to position the head of the inside of the concave portion, seal the concave portion in a detachable manner with a lid member, and configure the sealed housing portion with the concave portion and the lid member. Similarly, the shape of the pocket portion 99 is not limited to the box shape as in the embodiment, and various shapes such as a cylindrical shape can be applied.

[0038] Further, in the second embodiment, when the unit body 110 is previously formed with knockout holes 160 that allow easy opening of four duct openings D1 to D4 in two rows and two rows. Although exemplified, the number and shape of the planned duct opening may be arbitrary. For example, as shown in FIG. 16, knockout holes corresponding to four horizontal rows of scheduled ducts D1 to D4 may be formed symmetrically. In this case, when reducing the blowout air volume of the blowout duct 150, the planned duct openings D2 and D3 are set to the duct opening DO, and when increasing the blowout air volume, all the planned duct openings D1 to D4 are opened. Duct port DO should be used. The shape of the knockout hole is not limited to the narrow hole shape, and various hole shapes such as a round hole may be applied.
