This is because the casing functions as a soundproof wall, and such an arrangement of the casing is effective in suppressing sound transmission.

On the other hand, when a filter is provided at the suction port as in the air conditioner of Patent Document 2, when the housing is brought close to the wall surface and the side wall portion with the suction port is disposed toward the wall surface, the filter is cleaned for filter cleaning. Every time it is removed, it is necessary to remove the housing from the wall surface, and the work becomes complicated. Furthermore, the type in which a duct is attached to the air outlet of the housing restricts the range of movement of the housing, so that a space for removing the filter by separating the housing from the wall cannot be provided in the first place. There was a problem.

In addition, it is conceivable that the filter is provided in the housing instead of the suction port. However, since air flows from the bottom to the top in the housing, simply placing the filter in the air flow path As a result, the dust adheres to the lower surface of the filter, and the dust falls into the housing and the housing cannot be kept clean. In addition, even when the arrangement of the suction port and the air outlet is not the lower side and the upper side of the housing, respectively, there is a flow path in which air travels upward in the housing, and the same problem occurs when a filter is provided in the flow path.
