Further, between the front end of the upper panel 3 and the front end of the lower panel 3, an access port 9 through which the filter 10 can be freely inserted and removed is formed.
[0020]
As shown in FIG. 3, the dust box 11 is composed of an upper box 11a and a lower box 11b, which are divided into upper and lower parts, between which are formed front and rear openings 13 through which the filter 10 passes. . FIG. 4 is an exploded perspective view of the dust box 11, in which a first brush 14 and a second brush 15 are provided on the inner wall of the upper box 11a one after another, and the first brush 14 is pulled out of the filter 10. When the second brush 15 is pulled out, the second brush 15 is planted obliquely so as to face the pulling-out direction.
[0021]
At the center of the lower box 11b, a first gear 17 rotatably supported by a pair of partition plates is provided, and on both sides thereof, the first gear 17 faces the second brush 15 provided on the upper box 11a. , A third brush 16 is implanted.

As shown in FIG. 5B, a rack 10e in which a plurality of gears are formed in a straight line is provided on the back surface of the center beam 10c.
[0023]
When the filter 10 passes through the inside of the dust box 11, as shown in FIG. 6, the first brush 14 and the second brush 15 provided in the upper box 11a contact the front side of the filter 10, and The third brush 21 provided in the lower box 11b comes into contact with the back side. Further, the first gear 17 meshes with a rack 10e provided on the back surface of the center beam 10c.
[0024]
The lower portion of the dust box 11 is provided with the rewinding device 12 as described above, and the upper portion of the rewinding device 12 meshes with the lower side of the first gear 17 as shown in FIG. A second gear 22 pivotally supported by the second shaft 22a, a spiral spring 23 having one fixed to the second shaft 22a, a damper device 24 having an upper side meshing with a lower side of the second gear 22; A cover 12a covers these.
[0025]
As shown in FIG. 7, the spiral spring 23 is wound in a spiral shape, and protrudes from a first spiral portion 23a rotatably supported by the second shaft 22a and a side wall of the cover 12a. The first spiral part 23a and the second spiral part 23b are connected by a spring material so that the first spiral part 23a and the second spiral part 23b rotate in the opposite directions. When a spring material is wound from the first spiral part 23a to the second spiral part 23b, a rotational force is generated in the first spiral part 23a in a direction opposite to the winding direction, and the rotational force is always constant. It can be towed by traction.
[0026]
As shown in FIG. 8, the upper box 11a and the lower box 11b are provided with positioning portions for positioning the filter 10, and the lower end of the upper box 11a has a rectangular projecting piece 26. However, a concave portion 27 corresponding to the protruding piece 26 is formed in the lower box 11b, while a notch 25 corresponding to these is formed at one end of the filter 10, The front, rear, left and right positioning of the filter 10 can be performed by making 25 correspond to the projecting piece 26.
[0027]
Next, the operation will be described. When dust accumulates on the front and back surfaces of the filter 10 due to long-term operation and needs to be cleaned, as shown in FIG. 1, the filter 10 is manually pulled out from the inlet / outlet to the near side. As shown in FIG. 6, when the filter 10 moves, the first brush 14 scrapes up the dust accumulated on the surface and collects the dust in the upper box 11a. The second brush 15 captures and collects dust that cannot be removed and collects the dust in the upper box 11a. The third brush 21 scrapes dust accumulated on the back surface of the filter 10 and collects the dust in the lower box 11b.
[0028]
When the filter 10 moves, the first gear 22 meshed with the rack 10e rotates, and accordingly the spring material of the spiral spring 23 moves from the first spiral portion 23a to the second spiral portion 23b. It is to be wound to the side. When the filter 10 is pulled out to the terminal end and the cleaning is completed, the hand is removed from the filter 10 to be free. As a result, a rotational force is generated in the second gear 22 of the rewinding device 12 in a direction opposite to the direction in which the filter 10 is pulled out by the spiral spring 23, and the second gear 22 is automatically stored in the main body. ing. Further, at this time, a damper device 24 provided in the rewinding device 12 is configured to be gradually stored so as not to cause danger.
