DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A fan cleaning method, a fan cleaning apparatus and a fan cleaning vehicle according to the present invention will be described below with reference to the accompanying drawings.

[Fan Cleaning Method] In the fan cleaning method of the present embodiment, a dirty fan is immersed in a cleaning liquid and rotated to perform cleaning. This fan includes an axial fan and a multi-blade fan. Sirocco fans are particularly effective. These fans are connected to a rotating shaft of a motor, immersed in a cleaning tank storing a cleaning liquid, and rotated by a motor. The rotation direction of the fan is mainly rotated in a direction opposite to the normal rotation of the fan.

According to this method, when the fan on which oil stains or the like are stuck is rotated in the washing liquid, the washing liquid strongly contacts the dirt on the surface of the fan, and the dirt is gradually removed. And when the dirty fan is rotated in the cleaning solution for a certain time,
The dirt on the fan will be removed.

In particular, a sirocco fan has a large number of blades. However, when the sirocco fan is rotated in the cleaning liquid, the cleaning liquid flows on the surface of each dirty blade and strongly hits the dirt on the surface of each blade. , And gradually remove dirt. That is, by simply rotating the sirocco fan in the cleaning liquid, it is possible to simultaneously clean the surfaces of all the blades in a short time.

When the sirocco fan is rotated in the cleaning liquid, the cleaning liquid is agitated, so that care should be taken so that the cleaning liquid does not overflow from the cleaning tank. In addition, since a large amount of foam is generated by stirring, the amount overflowing from the washing tank is collected. This will be described later.

Similarly, when the axial fan is rotated in the cleaning liquid, the cleaning liquid flows on the surface of each contaminated blade and strongly hits the dirt on the surface of each blade, and the dirt is gradually removed. Then, as with the sirocco fan, care is taken so that the cleaning liquid does not overflow. In addition, foam generated in large quantities and overflowing from the washing tank is collected.

As described above, if the dirty fan is rotated in the cleaning liquid for a certain period of time, the dirt will be removed from both the sirocco fan and the axial fan. In particular, in the case of a sirocco fan, the number of blades is very large and the gap between the blades is narrow. However, since all blades can be cleaned at once, the efficiency of the cleaning operation is improved.

The direction in which the fan is rotated in the cleaning liquid is mainly opposite to the normal rotation, in order to remove dirt more efficiently. In general, dirt tends to accumulate in portions where air flowing on the surface of each blade is strongly hit. When the fan is rotated in the reverse direction, the cleaning liquid flows in the direction opposite to the air flowing on the surface of each blade, and acts to remove accumulated dirt from the opposite direction. This makes it easier for the firmly adhered dirt to come off.

For this reason, if the dirty fan is rotated in the cleaning solution in the reverse direction, the dirt on the fan is removed in a short time. In particular, in the case of a sirocco fan, the number of blades is very large and the gap between the blades is narrow. However, all the blades can be washed to the depth of the gap at once in a short time. As a result, the efficiency of the cleaning operation is greatly improved.
