よりも集塵効率の高い集塵装置を提供することである。However, in the dust collecting device (10), as shown in FIG.
Since a swirling flow as indicated by an arrow is generated in the dust collecting chamber (36) with the rotation of (2), the dust collecting chamber (36) passes through the air inlet (34) from the dust suction port (3). There was a problem that the flow rate of the airflow flowing into the inside was reduced, and the dust collection efficiency was low. As the rotating brush (2) rotates counterclockwise as indicated by the arrow, the brush cover wall (93) and the brush portion of the rotating brush (2) are rotated.
Air is entrained in the gap W formed between the outer peripheral end of (21) and the air as shown by the arrow, and the entrained air becomes an airflow that blows out from the dust suction port (3) to the front of the dust collector. However, there is a problem that the dust (53) on the floor (5) is blown off in the direction shown by the arrow. Further, the dust swept up by the rotating brush (2) is caught in the gap W, and the dust collection chamber (3)
6) Sometimes not collected. Further, the airflow flowing from the dust suction port (3) flows into the end of the brush cover wall (93).
(93a), the airflow was disturbed as indicated by the arrow, and the flow rate of the airflow flowing into the dust collection chamber (36) was reduced, resulting in low dust collection efficiency. Then, an object of the present invention is to provide a dust collecting device having higher dust collecting efficiency than the conventional one.

As shown in (1), when the rotary brush (2) is driven to rotate, an airflow flowing from the dust suction port (3) into the dust collecting chamber (36) through the airflow passage port (34) is formed. Here, the airflow flowing from the dust suction port (3) is guided substantially vertically upward along the wall of the airflow guide wall (81), and the direction of the airflow is aligned. The generation of the airflow circling in the dust chamber is suppressed. As a result, the flow rate of the airflow increases, and a suction airflow is generated at the dust suction port (3). As a result, the dust swept up by the rotation of the rotating brush (2) in the direction of the arrow is guided substantially vertically upward along the wall of the airflow guide wall (81), and further flows into the dust collection chamber (36). Follow the airflow as shown by the airflow passage (34)
Through the dust collection chamber (36). The air in the dust collection chamber (36) passes through the filter (37) and is discharged from a plurality of exhaust ports (38) formed in the upper wall of the dust collection chamber (36).

Similarly to the dust collector of the embodiment, an airflow flowing from the dust suction port (3) into the dust collection chamber (36) through the airflow passage port (34) is formed, and the airflow is unidirectionally controlled by the airflow guide wall (81). Therefore, the generation of an airflow that swirls in the dust collection chamber as in the conventional dust collection device is suppressed. As a result, the flow rate of the airflow increases, and a suction airflow is generated at the dust suction port (3). As a result, the dust swept up by the rotation of the rotating brush (2) in the direction of the arrow is housed in the dust collecting chamber (36) through the airflow passage (34), as in the first embodiment, and the dust is collected in the dust collecting chamber. The air in (36) is discharged from the exhaust port (38) through the filter (37).

Is sharp at an acute angle, so that the airflow guided substantially vertically upward along the wall of the airflow guide wall (81) as shown in FIG. 3 is largely undisturbed by the collision with the end (83a). Of the dust collection chamber (3
6). Thereby, the flow rate of the airflow flowing into the dust collection chamber (36) increases, and as a result, a larger suction airflow is generated. Furthermore, since the gap between the brush cover wall (83) and the outer peripheral end (21a) of the brush portion (21) of the rotating brush (2) is sufficiently small, the amount of air entrained in the gap is extremely small, The flow rate of the airflow blown in front of the dust collecting device with the rotation of the rotating brush (2) is extremely small.
Also, the amount of dust caught in the gap is extremely small.

る。As described above, according to the dust collector of the present invention, the flow rate of the airflow flowing from the dust suction port (3) into the dust collection chamber (36) through the airflow passage port (34) increases. Since the suction airflow is generated at the dust suction port (3), the dust collection efficiency is improved as compared with the conventional dust collector. Also, there is no danger of blowing dust toward the front of the dust collector, and the brush cover wall
(83) and the outer peripheral end (21a) of the brush part (21) of the rotating brush (2)
Since the amount of dust caught in the gap between the dust collecting device and the dust collecting device is greatly reduced, the dust collecting efficiency is greatly improved as compared with the conventional dust collecting device.
