Since the conventional ceiling-mounted air conditioner is configured as described above, there are an air outlet 13 and an inlet 1 on the ceiling 17.
5. It is necessary to install three inspection ports 18. In addition, after long-term use, dust may accumulate on the fan 4, resulting in a significant drop in air blowing performance, and the heat exchanger 2
Dust accumulates, reducing heat exchange performance and increasing air resistance. In addition, dust adhered to the drain pan 3, preventing the condensed water from draining smoothly.
There is a high possibility that the heat exchanger 2, drain pan 3, and fan 4 will overflow and stain the ceiling 17, etc., and the heat exchanger 2, drain pan 3, and fan 4 require periodic inspection and cleaning. There was a problem that the structure was not designed to allow cleaning work. In other words, the second
Even if the inspection port 18 shown in FIG.
Furthermore, in order to inspect and clean the heat exchanger 2, it is necessary to remove at least the drain pipe 10, and such work is practically impossible.

This invention was made in order to solve such problems, and the purpose is to obtain an air conditioner in which the drain pan, fan, heat exchanger, etc. can be inspected and cleaned.

In addition, this invention aims to simplify the installation work and improve the aesthetic appearance of the ceiling by using the inspection port, air outlet grill, and suction grill that must be installed in the ceiling to serve as both the intake grill and the inspection port.

[Means for solving problems]

The ceiling-mounted recessed air conditioner according to this invention has an inspection port that serves as an inspection port and a suction grill at the bottom of the air conditioner, and from that part, the filter, fan, and drain pan can be removed and the main body including the heat exchanger can be removed. This makes it possible to inspect the inside, as well as inspect and clean the outside of the main body, such as piping.

[Effect]

By using the above-mentioned means, this invention improves the aesthetic appearance of the ceiling surface because there is only an inspection port and a blow-off grill on the ceiling, and the structure allows for easy inspection of contamination, especially in the fan, drain pan, and heat exchanger, which greatly improves the appearance of the ceiling. This prevents problems such as performance deterioration and condensed water overflow.
