DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to an integrated air conditioner of the ceiling-embedded type that is embedded in the ceiling space of a building or the through-the-wall type that is installed through the wall of the building. Regarding machines.

(b) Conventional technology A partition plate that divides the interior of the exterior case of an integrated air conditioner into an indoor chamber and an outdoor chamber is formed in a planar L-shape, and this L-shaped interior is used as an indoor chamber; The one with a pair of outdoor heat exchangers installed along the back side of the outdoor chamber is the 52-5 Utility Model.
It is presented in Publication No. 3409.

(c) Problems to be solved by the invention The air conditioner presented in the above publication has the advantage that the depth dimension of the air conditioner can be shortened because the compressor is housed on the side of the indoor chamber. Since the L-shaped partition plate itself is not strong enough, it is necessary to use a strong metal plate for the side plate of the exterior case that is connected to the partition plate. Since equipment such as a compressor, a heat exchanger, and an air blower were assembled after the components were connected, the side panels of the exterior case became a hindrance during assembly, making it difficult to work.

The present invention provides an air conditioner that solves these problems.

(d) Means for Solving the Problems The present invention provides that the partition plate that divides the interior of the exterior case into an indoor chamber and an outdoor chamber is formed into a substantially U-shape in plan, and its lower end is placed above the bottom plate of the exterior case. At the same time, the indoor heat exchanger is fixed across the opposing side plates of the partition plate.

(*) When a sheet metal partition plate bent into a substantially U-shape in the working plane is installed and fixed on the bottom plate, the partition plate itself becomes strong, and the indoor side heat is exchanged with the opposing side plates of this partition plate. By bridging the containers, the partition plate becomes a support that provides strength to the air conditioner.

After the compressor, outdoor heat exchanger, and indoor/outdoor blower are assembled, the front plate, back plate, left and right side plates, and top plate are assembled to form an exterior case.
