That is, the specific operation as an example includes two times of water supply and three times of air blowing.

  The specific operation will be described with reference to FIG. FIG. 4 is a flowchart showing the steps of the cleaning method according to the present embodiment. In FIG. 4, the user first sets the filter 17 at an appropriate position of the support portion 9, and then turns on the cleaning operation switch 51 to start the cleaning operation. When the cleaning operation starts, first, as the first air blowing step S1, only air from the air outlet 21 to the filter 17 in a state where the filter 17 is supported by the support portion 9 at the position where the support portion 9 is raised. Is done. Here, this blown air is not in the position where the support portion 9 is appropriately raised when the filter 17 is first set, that is, when the filter 17 is first set, the filter 17 is not in the fully raised position. In some cases, the support 9 and the filter 17 are raised. In the filter 17, a considerable amount of dust such as dust is blown off by the wind pressure received in the dry state by the first air blowing before washing with water.

  Next, after the first air blowing process, as the first water feeding process S2, only the water feeding from the water feeding port 27 is performed on the filter 17 while lowering the filter 17 together with the support portion 9. Subsequently, after the first water feeding step, as the blowing water feeding step S3, both blowing and water feeding are performed while the filter 17 is lifted together with the support portion 9 (corresponding to the above-mentioned second water feeding and third blowing). . In the filter 17, dirt that cannot be removed by blowing is removed by water pressure or a dissolving action by water. And since the 3rd ventilation is also performed at the time of the 2nd water supply, the effect | action which blows away a dirt with water and the increase effect of a water force are also obtained, and a higher dirt removal result is obtained.

  Then, after the blowing water feeding process, as the second blowing process S4, only the air blown from the blower opening 21 to the filter 17 with the filter 17 supported by the support part 9 at the position where the support part 9 is raised. Is done. The filter 17 that has been washed with water is dried by the blowing. Further, the drying by the second air blowing step S4 is completed very efficiently and in a short time because the drainage is progressed to some extent by the third air blowing in the previous air blowing water feeding step S3.

  As described above, according to the cleaning device and the like of the present invention, the cleaning work time can be shortened because the drying by blowing is obtained while improving the cleaning result of the ventilation member by washing with water. In addition, since the rough trash removal is carried out before washing with water, the effect of washing with water is extremely high. In addition, since the two functions of dust blowing and drying are exhibited by one air blowing means, the apparatus can be made compact and light. Furthermore, it is possible to complete the trash removal, washing with water and drying with a single device. In addition, these series of steps are all automatically performed and can be completed.

  Moreover, in this Embodiment, since water supply or ventilation is performed while raising / lowering a ventilation member, it can act on a plate-shaped ventilation member uniformly. Furthermore, since the third air is sent together with the second water supply, the effect of removing dirt is extremely high. In addition, when the third air blowing is performed together with the second water feeding, the air blowing port injects air above the water feeding port, so that the supplied water is covered with the jet air from above. An action of pressing down is also obtained, and it is possible to suppress water scattering to some extent during washing with water. In addition, since the cleaning device body includes a moving carriage function, the cleaning device can be easily moved, and it is easy to carry in and install the product on the site. it can.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.

  For example, the ventilation member in the present invention is not necessarily limited to what is called a filter, that is, includes a wide range of members that are not expected to have a filtering action to block a specific target from the circulating fluid. Therefore, any member may be used as long as it is disposed in front of, behind, or in the middle of the fan, propeller, or the predetermined flow path, allows passage of gas, and has a portion that crosses the fan or the predetermined flow path in a projection direction. The name may be anything such as a net, a protective grille, etc.
