ある。 As shown in FIG. 5, the branch chamber 6 has an inner chamber inspection port 10 formed at its bottom, and the interior thereof can be inspected by opening and closing a lower lid 11 for opening and closing the inspection port. A damper 12 that can be opened and closed is provided at the attachment portion of each of the branch ducts 7 to the branch chamber 6, and an electric circuit board 13 for various controls such as adjusting the opening degree of the damper 12 is mounted on the upper inner wall surface of the damper 12. It is attached to.

いた。 When the branch chamber 6 is installed with these relative positions shifted, as shown in FIG.
As a result, after removing the inspection port opening/closing plate 17 on the ceiling 14, it is necessary to remove the inspection port opening/closing lower cover 11 and then reach into the branch chamber 6. Another problem is that it is difficult to repair and inspect the inside of the branch chamber 6 and the electric circuit board 13. Furthermore, if the lower lid 11 for opening and closing the inspection port has a completely flat shape, it may be removed during assembly or inspection of the air conditioner 1 or the branch chamber 6, for example, by placing it on the floor and reinstalling it. It is difficult to handle when trying to pick it up, and some kind of improvement has been desired.
