A plurality of positioning members are attached along the edge of the. By attaching the positioning member in this manner, when the positioning member protrudes from the edge of the main body and sticks the ceiling plate, the edge of the ceiling plate is prevented from being very close to the main body or coming into contact with the main body. Thus, by making the edge of the ceiling panel not very close to or in contact with the main body, it is easy to perform service inspection around the main body, and vibration caused by operation of the main body is not transmitted to the ceiling panel.

(C) Problems to be Solved by the Invention Here, when the ceiling panel is attached, it is difficult to handle the ceiling panel because it is faced upward, and therefore the corners of the ceiling panel are not covered with the positioning members. For example, such devices may be damaged by hitting them against a heat exchanger, a blower, or the like, or hooking them on a lead wire.

In addition, when the contractor performs interior construction work inside the room with the air equipment supplier attaching the main body to the ceiling space (the state where the decorative panel is not attached to the main body), dust and the like accompanying this work enter the main body, There was also a risk that the equipment inside would be dirty.

An object of the present invention is to make it difficult for a main body attached to a ceiling space to be scratched and for dust and the like to enter into the main body.

(D) Means for Solving the Problems In order to achieve this object, the present invention sets the size of the positioning member for maintaining a gap between the main body of the air conditioner and the opening of the ceiling plate to reduce the entire lower surface of the main body. The size is set to cover.

(E) Operation When the positioning member is attached to the lower surface of the main body, the ventilation hole on the lower surface of the main body is closed by this member, and the edge of the positioning member protrudes from the entire periphery of the main body.

20 is a concave portion provided on the right edge. Reference numeral 24 denotes a mounting piece obtained by cutting and bending substantially the center of the first positioning member 20, and the mounting piece 24 is directed outward (in the direction of the solid arrow in FIG. 2) by elastic force. Therefore, when attaching the first positioning member 20 to the lower right side of the main body 1, first put a hand through the notch 25, raise the attachment piece 24, and then attach the attachment piece 24 to the inner surface of the drain pan 11. At the same time, the concave portion 23 of the member 20 is hooked on the head 27 of the mounting screw 18 on the right side of the main body. In addition, overhang piece 22 of notch 21
Is bent as shown by the solid arrow in FIG. At this time, since the mounting piece 24 is exerted on the outer side by the elastic force, that is, the force toward the inner side surface 26 of the drain pan 11, the inner side surface 26 becomes the mounting portion of the positioning member 20, and the positioning member 20 falls. There is no danger. 28
Is a second positioning member, which is also formed of cardboard. The width dimension a of the central portion 29 of the second positioning member 28 is set slightly larger than the width dimension b of the concave portion 30 of the main body 1. Therefore, when attaching the positioning member 28 to the lower left side of the main body 1, the central portion 29 is attached to the concave portion 30 of the main body 1.
