[0021]
At the four corners of the grille frame 4, cushioning materials 42 for absorbing the impact at the time of the fall are attached in case the packed grille frame 4 is dropped during transportation or the like. ing. Then, the grill frame 4 and the elevating grill 200 (the suction grill 10) are packed in one packing box 43 by a packing device. As described above, since the grill frame 4 and the elevating grill 200 are packed in an assembled state, the elevating operation of the elevating grill 200 can be inspected at the time of factory shipment.
[0022]
When attaching the grill frame 4 and the elevating grill 200 to the main body 1, the operator takes out the grill frame 4 and the elevating grill 200 from the packing box 43, and attaches the cushioning members 42 attached to the four corners of the grill frame 4.

Next, the operator sends the grill frame 4 to the main body 1 so that the front side of the grill frame 4 faces down. Then, the operator temporarily fixes the grill frame 4 to the main body 1 by using the screw holes 30 provided in the above-described screw holes 30 (see FIG. 3), which are not covered by the suction grill 10. After that, the adhesive tape 51 that temporarily fixes the suction grill 10 to the grill frame 4 is peeled off, and the suction grill 10 is carefully lowered so that the temporarily fixed grill frame 4 does not drop. Thereby, the screw hole 30 covered and hidden by the suction grill 10 appears. In addition, since the hanging strings 12, 13, and 14 are previously extended, a suction area is formed as shown in FIG. 6 so that a worker can insert a tool such as a screwdriver into the lower surface of the grille frame 4. The grill 10 is supported while being lowered from the grill frame 4.
[0023]
Next, the operator fixes the grill frame 4 to the main body 1 using the screw holes 30 including the screw holes 30 covered and hidden by the suction grill 10, and also fixes the suction grill 10 and the long life filter. Then, the cardboard 40 that bundles the bundles 11 is removed, and all the packaging of the grille frame 4 and the elevating grille 200 (the suction grille 10) is removed. Then, the unit 21 of the grille frame 4 is energized, and the hoisting strings 12, 13, 14 are wound up on the bobbin, so that the lifting grill 200 (the suction grille 10) supported in the lowered state is raised, and the grille frame 4 In the state where it is stored. Next, the worker performs an air-conditioning operation (for example, a cooling operation) in order to confirm the operation of the ceiling-mounted air conditioner 100.
[0024]
When cleaning the long life filter 11, the operator operates the remote controller (not shown) which communicates wirelessly with the control device in the unit 21 to lower the suction grill 10 into the control device. Instruct. When receiving the instruction, the control device controls the driving of the stepping motor, rotates the bobbin to extend the hanging strings 12, 13, and 14, and lowers the suction grill 10. At this time, the extension amounts of the suspending cords 12, 13, and 14 which are extended from the unit 21 are maintained at the same amount by the control device, and the suction grill 10 is lowered while maintaining a substantially horizontal state. When the suction grill 10 is lowered to a position Y slightly higher than the filter replacement position X shown in FIG. 1, the control device (not shown) starts counting the first time. The first time is a time until the suction grill 10 is lowered from the position Y to the filter replacement position X. While the first time is counted, the suction grill 10 is lowered to the filter replacement position X in a horizontal state. When the suction grill 10 is lowered to the filter replacement position X, the bobbin around which one suspension string 14 is wound is detached from the drive system of the stepping motor via, for example, a clutch or the like, and the one suspension The feeding of the string 14 is stopped.
[0025]
Then, the control device (not shown) starts counting the second time. The second time is a time during which the suction grill 10 is tilted from the horizontal state to the tilt angle a. During this second time, only two suspension cords 12 and 13 are paid out from the unit 21, and the suction grill 10 is tilted from the horizontal state to the center portion side (air discharge side) of the conditioned room. When the suction grill 10 is tilted to the tilt angle a, the drive of the stepping motor is stopped by a control device (not shown), the feeding of the two suspension strings 12, 13 is stopped, and the descent operation is stopped.
[0026]
Here, the filter replacement position X is a low position where a worker can perform maintenance work. The filter replacement position X is a position where, for example, in a living space having a ceiling height of about 2.5 m, the hanging strings 12, 13, and 14 are extended from the ceiling by about 1 m, and the suction grill 10 is lowered by about 1 m. The suction grill 10 is about 1.5 m above the floor. In addition, the inclination angle a is an angle at which the surface of the filter 11 can be confirmed in the field of view of an operator located on the wide area side of the living space (center side of the harmonized room) at the filter replacement position X. Is desirable. For example, it is inclined by 45 degrees from the horizontal position toward the center portion (air discharge side) of the conditioned room. In the filter replacement position X, the filters 11 and 25 are removed from the suction grill 10 by an operator, and are cleaned and replaced.
[0027]
After the cleaning and replacement, the operator instructs the control device to raise the elevating grill 200 by operating the above-described remote controller. When receiving such an instruction, the control device starts counting the third time. This third time is a time until the suction grille 10 tilted at the tilt angle a returns to the horizontal state. When the third time starts counting, the stepping motor is driven, the winding of the two suspension strings 12 and 13 is started, and the suction grille inclined toward the center (air discharge side) of the harmonized chamber. One end of 10 is raised while returning to a horizontal state. Here, the bobbin around which one suspension string 14 is wound is separated from the drive system of the stepping motor via, for example, a clutch or the like, and the winding of the suspension string 14 is stopped.
[0028]
Next, when the suction grill 10 is returned to the horizontal state, the bobbin around which one suspension string 14 is wound is further connected to the drive system of the stepping motor, and the upper suction grill 10 is raised in the horizontal state. Then, the suction grill 10 is inserted into the grill frame 4 in a horizontal state. When the suction grill 10 is inserted into the grill frame 4, the ascending operation is stopped by a control device (not shown).
[0029]
As described above, according to the present embodiment, since the grill frame 4 and the elevating grill 200 (the suction grill 10) are packed in an assembled state, the elevating grill 200 is attached when the grill frame 4 is attached. Work for attaching the grill frame 4 and the elevating grill 200 to the main body 1 is simplified. In addition, since the elevating grill 200 is attached to the grill frame 4 in advance, when the operator attaches the elevating grill 200 to the grill frame 4, it is possible to prevent the elevating mechanism of the elevating grill 200 from being erroneously damaged.
[0030]
Further, at the time of packing, the hanging cords 12, 13, and 14 are drawn out in advance, and when the grill frame 4 is addressed to the lower end of the main body 1, a driver or the like is provided between the grill frame 4 and the suction grill 10. The suction grill 10 is supported in a lowered state so that the tool can be inserted. Thereby, the operator can screw and fix the grill frame 4 to the main body 1 by using the screw holes 30 formed at locations that are covered and hidden by the suction grill 10 during storage.
[0031]
Further, according to the present embodiment, since the substantially central portion of the other side edge 10B on the long side of the suction grille 10 is supported by one hanging string 14, at least the substantially central portion of the other side edge 10B is When the suction grille 10 is retracted, it is completely lifted by the single hanging string 14. Further, when it is completely lifted, the contact body 23 comes into contact with the lower surface of the storage portion of the grille frame 4, so that the position of the approximate center of the other side edge 10B is completely positioned. Therefore, the possibility that the central portion of the suction grill 10 is deformed into a downwardly convex state and stored by the own weight of the suction grill 10 is eliminated.
[0032]
Furthermore, according to the present embodiment, at the time of cleaning and replacing the filter 11, the suction grill 10 is lowered and tilted toward the center portion (air discharge side) of the conditioned room, so that the worker A The state of the filter 11 can be confirmed, and the attachment / detachment work of the filter 11 can be easily performed. After the filter 11 is cleaned and replaced, the suction grill 10 is returned from the inclined state to the horizontal state and rises in the horizontal state, so that the suction grill 10 is smoothly and smoothly mounted on the grill frame 4. be able to. Further, since the suction grill 10 is raised while maintaining a horizontal state, vibration of the suction grill 10 can be suppressed.
[0033]
As described above, the present invention has been described based on the above embodiment, but the present invention is not limited to this.
[0034]
For example, when the suction grill 10 is housed in the grill frame 4 and the unit 21 is in a non-energized state during test operation or cleaning and replacement of the filter, the suction grill 10 cannot be lowered. Therefore, as shown in FIG. 7, a hook 60 having a shape to be hooked on the rib of the suction grill 10 is packed together with the grill frame 4 and the suction grill 10. The hook 60 is hooked on a rib of the suction grill 10 so that the suction grill 10 is pulled down.
[0035]
Further, for example, in the above-described embodiment, the one-way cassette type air conditioner has been described, but the present invention is also applicable to a two-way cassette type and a four-way cassette type. In this case, the direction in which the suction grill is inclined is not limited to the air discharge side.
