The brush body 2 rotates in a direction in which the filter F is rubbed downward with the brush 22. Further, the filter receiver 4 is raised to the standby position.
Further, the height of the height adjusting tool 8 is adjusted according to the size of the filter F to be cleaned up, and the filter F seems to pass through the brush body 2 when the filter receiver 4 is lowered to the maximum descending height. Set to. As a result, the entire filter F can be cleaned or washed, and a partially contaminated portion can be prevented from remaining on the filter F.
[0041]
A filter F is inserted from an entrance / exit 10 provided in the upper part of the casing 1. Most of the dirt on the filter F is removed by the water pressure of the cleaning liquid sprayed from the spray nozzle 3, and the filter F is rubbed downward by the brush 22 of the rotating brush body 2, thereby pulling in the filter F. Is stabilized by being pressed against the receiving member 40 of the filter receiver 4 below. Further, the brush 22 further removes dirt from the filter F.
[0042]
When the handle 61 is manually operated to rotate the rotary shaft 60 and the chain 63 is moved to lower the filter receiver 4, the filter F is also pressed against the filter receiver 4 and lowered while maintaining a stable state. The adjustment tool 8 moves down to a predetermined lowering height. As a result, the entire filter F is wet-cleaned by being sprayed with the cleaning liquid and rubbed with the brush body.
[0043]
The dust removed from the filter F is mixed with the cleaning liquid and falls onto the bottom plate 15 of the casing 1 and is discharged from the drain pipe 16 to the outside of the casing 1.
[0044]
In addition, when the brush 22 of the brush body 2 becomes dirty or foreign matter adheres to the brush 22, it is easy to clean by opening the opening / closing lid 12 so that the brush body 2 appears outside the casing 1. Further, when the brush 22 is worn out and the brush body 2 needs to be replaced, the replacement work is easy.
