Such a railroad vehicle is equipped with an air conditioner for air circulation or cooling and heating inside, and a filter that can block the inflow of foreign substances in the process of inhaling indoor air is installed and used in the air conditioner.

Here, since foreign matter accumulates when used for a long period of time, the filter must be periodically cleaned to remove foreign matter. In this case, the filter has a structure in which a fine metal net is embedded in the outer frame like a screen, and is easily separated and remounted for cleaning, and generally, it must be cleaned at least once a month.

However, while a number of filters are applied with only one railroad vehicle, there is a problem in that since the filter cleaning operation is performed by a manual method, more manpower is input than necessary, the work is very cumbersome, and a lot of time is required to clean the filter.

There is a known filter cleaning apparatus capable of improving the cleaning efficiency of the filter by spraying in different directions so that foreign matters stuck to the filter are released and removed.

However, in the case of the above-described prior art, since the filter is washed in an air odor method that continuously moves each filter on a conveying device such as a conveyor, it occupies a lot of work space, and the cleaning efficiency of the filter is lowered by washing the filter being transferred. In order to increase the efficiency, since the transfer of the filter from the transfer mechanism must be stopped continuously, there is a problem that workability is deteriorated and a lot of work time is required.

In addition, since the above-described conventional technology sprays washing water while the filter is exposed on the transport mechanism, it causes external environmental pollution by dust generated during the washing process, and the worker is directly exposed to work dust, which adversely affects health. There was a problem that it would cause.

Further, conventionally, since only washing operation using washing water is performed, drying of the filter is not performed properly immediately after washing, so that washing efficiency is deteriorated and additional manual drying operation by an operator is required.
