It should be noted that the present invention is not limited by this embodiment. FIG. 1(a) is a perspective view of a filter cleaning device according to the present invention, and FIG. 1(b) is a sectional view taken along line AA of FIG. 1(a). Also, FIG. 2(a) is a perspective view of the dust remover, and FIG. 2(b) is a front view of the dust remover. The outline of the filter cleaning device according to the present invention will be described below with reference to these drawings.

The filter cleaning device 10 includes a filter body 1 that captures dust, a rotary cleaning body 2 that abuts on the filter body 1 and removes dust adhering to the filter body 1, a rotary cleaning body 2 that abuts, Two dust removing bodies 20a and 20b having a plurality of comb teeth for removing dust transferred from the filter body 1 to the rotating cleaning body 2 are connected to the dust removing bodies 20a and 20b so that the dust removing bodies 20a and 20b remove the dust. The rotary cleaning body 2, the dust box 3, and the dust removing bodies 20a and 20b constitute a cleaning device main body 10a. The rotary cleaning member 2 is composed of a rod-like shaft 2a and a brush 2b having a plurality of bristles 8, 8, . . . formed on the outer periphery of the shaft 2a.

The dust box 3 has an opening 3a in the upper part, and the rotating cleaning body 2 is detachably arranged near the upper part of the opening 3a. The two dust removing bodies 20a and 20b are formed in the vicinity of the dust box opening 3a so that their longitudinal directions are substantially parallel and their comb teeth face each other. extending towards.

The cleaning device main body 10a includes a gear A5 that rotates while meshing with the racks 4, 4 arranged along the left and right longitudinal directions of the filter body 1, and a gear that meshes with the gear A5 and rotates when the gear A5 rotates. B6 and a gear C7 rotated by a motor (not shown) are installed, and the rotation of the gear C7 rotates the gear A5. Further, the gear B6 is connected to the shaft 2a of the rotary cleaning body 2, so that the rotary cleaning body 2 rotates when the gear B6 rotates.

As a result, the cleaning device main body 10a moves along the longitudinal direction of the filter body 1 together with the rotation of the gear A5. Then, the gear B6 meshing with the gear A5 also rotates, and the rotary cleaning body 2 connected thereto rotates. The filter body 1 includes a filter (not shown) and a grid frame that partitions the filter into a plurality of sections. In addition, by using a stepping motor to reversely rotate a motor (not shown), it is possible to move the cleaning device main body 10a in the direction opposite to the moving direction indicated by the arrow in FIG. 1(b). , the rotation direction of the rotary cleaning body 2 is also reversed. Thus, by reciprocating the cleaning device main body 10a in the longitudinal direction of the filter body 1, the dust adhering to the filter can be reliably removed.

The dust removing bodies 20a and 20b are attached at positions facing each other in the opening of the dust box 3, and the position of the comb teeth of the dust removing body 20a is higher than the position of the comb teeth of the dust removing body 20b (closer to the filter body 1). position). Further, the inclination angle of the dust removing body 20a with respect to the longitudinal direction of the filter body 1 is larger than the inclination angle of the dust removing body 20b. In the direction of rotation of the rotary cleaning member 2 indicated by the arrow in FIG. On the other hand, when the rotation direction of the rotary cleaning member 2 is reversed, the dust remover 20b contributes to the removal of the dust 9. As shown in FIG. The dust 9 accumulated at the roots of the dust removing pieces 21 and 22 falls toward the bottom of the dust box due to its own weight, and the inside of the dust box is filled with the dust 9.例文帳に追加

The dust removing bodies 20a and 20b have a comb-teeth shape having a plurality of comb teeth (dust removing pieces 21 and 22). ing. The dust removing pieces 21 and 22 are alternately formed of two types of dust removing pieces having different lengths. 22 is formed. As a result, a wide valley 23 is formed between the adjacent long dust removing pieces 21, 21, and a narrow valley 24 is formed between the long dust removing piece 21 and the short dust removing piece 22. By guiding the bristles 8 from the wide trough 23 to the narrow trough 24, the dust 9 adhering to the bristles 8 can be easily removed. The dust removing pieces 21 and 22 are not limited to two types having different lengths, and two or more types are included in the present invention. The present invention also includes a dust removing body in which two or more short dust removing pieces 22 are formed between adjacent long dust removing pieces 21 , 21 .

The filter cleaning device has two dust removing bodies 20a and 20b. The dust removing pieces 21 and 22 formed at the positions where one is the long dust removing piece 21 and the other is the short dust removing piece 22 . As a result, by repeating forward and reverse rotations of the rotary cleaning member 2, the dust adhering to the rotary cleaning member 2 can be evenly removed by the two dust removal members 20a and 20b.

Also, the projecting direction of the dust removing pieces 21 and 22 is formed to be substantially parallel to the longitudinal direction of the bristle material 8 at the position where the dust removing pieces 21 and 22 abut. This makes it easy to guide the bristles in contact with the tips of the dust removing pieces 21 and 22 to the troughs 23 and 24 formed between the adjacent dust removing pieces 21 and 22 .

Further, the tip of the dust removing piece 22 having a short length is made to abut on the tip side of the bristle material 8 rather than the tip of the dust removing piece 21 having a long length. As a result, the tip side of the bristle 8 is separated by the short dust removing piece 22 and guided to the narrow valley 24, so that the dust adhering to the bristle 8 can be easily removed.

The length of the long dust removing piece 21 is preferably 1.5 to 3.0 times the length of the short dust removing piece 22 . As a result, the brush 2b constituting the rotary cleaning member 2 is guided to the narrow valley 24 between the long dust removing piece 21 and the short dust removing piece 22 while the bristles 8 are prevented from spreading. Therefore, dust adhering to the bristles 8 can be removed more easily.

The long dust removing piece 21 has a substantially arc-shaped tip and is formed so that both sides thereof are substantially parallel. As a result, the bristles can be pushed aside without being damaged, and the spread of the bristles can be suppressed.

On the other hand, the short dust removing piece 22 has a substantially triangular tip. Thereby, the trough portion 24 can be narrowed to guide the bristles, and the dust adhering to the bristles can be removed more easily.

Similarly, the side of the long dust removing piece 21 and the side of the short dust removing piece 22 form an acute angle. As a result, the bristles can be guided by narrowing the troughs, and dust adhering to the bristles can be removed more easily.

3(a) to 3(d) are sectional views showing the first embodiment of the filter cleaning device according to the present invention. Note that the filter body is omitted and not drawn. The procedure for discharging dust in the filter cleaning device of the first embodiment will be described below with reference to these drawings.

In the filter cleaning device 10 of the first embodiment, hinges 11a and 11b are provided at two positions on the upper side of the dust box 3 and rotate in the direction in which the opening 3a of the dust box expands. As a result, two dust removers 20a and 20b, which are substantially parallel to each other in the longitudinal direction and have comb teeth facing each other, are rotatable with respect to the dust box 3 near the opening edge of the dust box. The position of the comb teeth of the dust removing body 20b is formed below the dust box 3 from the position of the comb teeth of the dust removing body 20a.

As the rotary cleaning member 2 rotates in the direction of the arrow, the dust removal member 20a that abuts from the tip side of the comb teeth functions to remove dust from the rotary cleaning member. The dust 9 collected in the dust box 3 is biased toward the dust remover 20a. Incidentally, when the rotary cleaning member 2 is rotated in the reverse direction, the dust removing member 20b abutting from the tip side of the comb teeth functions to remove the dust 9 from the rotary cleaning member 2, so that the dust collected in the dust box 3 is removed. 9 is biased toward the dust removing body 20b side. Therefore, when the rotary cleaning member 2 is rotated forward, the dust 9 can be removed by one dust removing member 20a, and when the rotary cleaning member 2 is rotated in the reverse direction, the dust is removed by the other dust removing member 20b. 9 can be removed, the dust removal performance can be improved.

In this state, when the left dust removing member 20a is rotated upward after removing the rotary cleaning member 2 in FIG. The clump of dust 9 in the dust box 3 is lifted up by the 9, but when the clump of dust 9 abuts against the dust removing body 20b on the right side, the clump of dust 9 can no longer move upward, and the clump of dust 9 can no longer move upward. Since the clump of dust 9 is peeled off from the dust removing body 20a, scattering of the dust 9 to the outside can be prevented.

In FIG. 3(b), when the rotary cleaning body 2 is removed after the left dust removing body 20a is rotated upward, the left dust removing body 20a is rotated upward. The dust adhering to the comb teeth of the dust removing body 20a lifts the dust clumps in the dust box 3 upward. Further, the clump of dust 9 cannot move upward, and the clump of dust 9 is peeled off from the dust remover 20a on the left side, so that the scattering of the dust 9 to the outside can be prevented. Moreover, since the opening of the dust box 3 is narrowed before the rotary cleaning member 2 is removed, the dust 9 can be prevented from scattering to the outside.

Then, as shown in FIG. 3(c), the right dust removing body 20b is rotated upward to maximize the opening 3a of the dust box, and then the dust box 3 is turned upside down as shown in FIG. 3(d). to complete the discharge of dust.
