を要する問題がある。However, the above prior art does not consider the case where a plurality of indoor units are installed in the same room such as a building or a store. Therefore, when cleaning the filter or suction grill, etc., it is necessary to individually check the lifting operation of the suction grill from the remote controller (remote control) corresponding to each indoor unit, especially in the case of four or more indoor units. When the units are installed in the same room, there is a problem that the lifting operation of the suction grill requires a lot of time even during the cleaning work.

It is desirable to use C). However, R407C has poor heat exchange efficiency, and it is necessary to frequently clean the filter and the suction grill.

Or, if only one unit is to be cleaned and inspected, it is also required to lift and lower the suction grille individually.

Therefore, when the cleaning of one indoor unit is completed and the next indoor unit is cleaned, the efficiency of the cleaning operation can be remarkably improved as compared with the case where the lifting operation of the suction grill is performed again.

Even if there is an obstacle such as a shelf below, it is possible not to contact the obstacle below or the floor. The workability of cleaning, inspecting and replacing the filter and the suction grill can be improved.

ている。In FIG. 1, reference numeral 1 is a decorative panel of a unit body which is an indoor unit of a ceiling-embedded air conditioner. Inside the unit body, a heat exchanger, a drain pan, a blower, a fan and a fan motor (not shown). The decorative panel 1 is detachably attached to the lower part of the decorative panel 1 so as to cover the opening. At the center of the decorative panel 1, a suction grill 2 is supported by a wire 4 wound around a rotary drum 10, as shown in FIG. Further, the filter 5 is attached to the suction grill 2 so as to be detachable.

In particular, when using a CFC-free alternative CFC, specifically an HFC refrigerant (R407C), the heat exchange efficiency is poor and it is necessary to frequently clean the filter and the suction grill. Therefore, it is necessary to allow the lifting mechanism of the suction grill 2 to lower the suction grill to facilitate maintenance such as cleaning and replacement. However, in a building, a store, etc., there are many cases where a plurality of unit bodies are installed in the same room, and it is inefficient to raise and lower each unit body.

えば、部屋全体の作業に要する時間を短縮できる。In the embodiment shown in FIG. 1, the remote controller 3 is connected to a plurality of unit bodies, and the single remote controller 3 controls the raising and lowering of the plurality of suction grilles 2. Then, if the suction grill 2 is lowered almost at the same time and the cleaning work is performed at one time, the time required for the work of the entire room can be shortened.

リル２を同時に下降させることが望ましい。In this embodiment, the remote controller 3 is provided for a plurality of indoor unit bodies, but the remote controller 3 may be installed for each unit body. Even in this case, it is desirable that the arbitrary one remote controller 3 simultaneously lowers the suction grilles 2 of the arbitrary plural air conditioners to which the remote controller 3 is not connected.

Further, if the suction grill 2 can also be detached from the wire 4, it can be washed by washing it in a bucket 11 or the like at a place such as a tap as shown in FIG. After cleaning the filter 5, the filter is mounted on the suction grill 2 again, and the remote control 3 is operated to reverse the rotary drum 10 to wind up the wire 4, raise the suction grill 2, and attach the micro to the makeup panel 1. A detector (not shown) such as a switch raises the suction grill 2 until it is housed in the decorative panel 1.

作を制御する。FIG. 2 shows a case in which only the suction grill 2 of one of the plurality of unit bodies is moved up (down). If you need to raise and lower the suction grille individually, such as when there is an obstacle in the building or the construction structure of the building, or if there is an obstacle underneath, or if you want to inspect only a specific unit body, you can raise and lower it arbitrarily from the remote control 3. The unit main body to be operated is selected, and the lifting operation of only the suction grill 2 of the selected unit main body is controlled.

ようになる。When the remote controller 3 is installed for each unit body, the remote controller is provided with a unit for selecting the unit body, and the suction grille 2 of a specific unit body arbitrarily selected by any one remote controller 3. You may control only raising and lowering. In this case, it is desirable that even if the remote controller 3 is not directly connected, any suction grill 2 can be moved up and down if the respective unit bodies are connected. Further, when the unit body is selected by the remote controller 3, the number of the unit body is selected, but the suction grill 2 selected when the unit body is selected is provided with a function of slightly descending. As a result, the selected unit body can be visually confirmed.

As a result, it becomes possible to easily understand which indoor unit is moving up and down.

なり、清掃作業時間の短縮が可能となる。As described above, when cleaning, inspecting, or replacing the filter 5 or the suction grill 2, the suction grills of all the indoor units can be moved up and down at the same time. For example, four or more indoor units can be placed in the same room. Even when the unit is installed, the time required for the lifting and lowering operation of the suction grill becomes the same as in the case of one indoor unit, and the cleaning work time can be shortened.

It can also be advantageous for energy saving.

If it is 407C, it can be made suitable for global environment protection. Since the suction grills of the plurality of unit bodies can be moved up and down by the remote control, the filters and the suction grills can be frequently cleaned. Therefore, there is no fear of destroying the ozone layer, the heat exchange efficiency is good, and the cooling / heating capacity is excellent.

It becomes possible to do.
Therefore, it is possible to obtain a ceiling-embedded air conditioner that can significantly improve the efficiency of cleaning work.
