A method is adopted in which the air in the room is sucked by a blower, passed through a heat exchanger to exchange heat, and then introduced into the room. In that case, powder adheres to the inside of the heat exchanger or the air conditioner and the inside of the air conditioner becomes unsanitary, or the powder closes the heat exchanger, which reduces the heat exchange efficiency and the amount of air blown, and the air conditioning function is reduced. There was a problem that it caused trouble. To avoid this,
A filter may be provided on the inlet side of the heat exchanger, but the filter is clogged with the powder, and the air conditioning function deteriorates as described above.

ができる。As described above, according to the present invention, it is possible to provide an internal automatic cleaning air conditioner that automatically cleans powder adhering to the inside of a casing or a heat exchanger without manpower. Further, by providing the automatic cleaning mechanism, it is possible to provide an internal automatic cleaning air conditioner that can be installed regardless of whether it is a floor-standing type or a ceiling-suspended type. Also, the switchgear,
Since the upstream casing and the downstream casing provided with the cleaning device and the drain pan, the heat exchanger, and the constituent members such as the blower chamber are independent units, the constituent members can be separately carried in and installed, It can contribute to labor saving during on-site construction. Furthermore, by providing an automatic cleaning mechanism and an automatic drying mechanism using the switchgear, the inside of the casing, the inside space of the air conditioner such as a heat exchanger, the outside space of the air conditioner, and the air-conditioned room can be easily installed during and after cleaning. It is possible to provide an internal automatic cleaning air conditioner capable of maintaining low humidity.
