The dust collecting device 20 includes a substantially cylindrical dust collecting case 21 formed of a transparent synthetic resin, and a cylindrical cylindrical body 22 rotatably mounted in the dust collecting case 21. A main filter 23 removably attached to the dust collecting case 21 inside the cylindrical body 22, a lid 24 for opening and closing a dust discharging opening formed on the upper surface side of the dust collecting case 21; It is composed of

The cylindrical body 22 is rotatably sandwiched between a main filter 23 and a side surface facing the opening of the dust collecting case 21 so that the cylindrical body 22 can be removed together with the main filter 23 from the opening of the dust collecting case 21. Has become. The cylindrical body 22 is provided with a mesh-shaped pre-filter 25 in substantially half of the lid 24 side, and a spiral body 26 is provided over substantially the entire outer periphery. A dust remover (not shown) is provided inside the tubular body 22, and when the tubular body 22 rotates, the dust attached to the main filter 23 is removed by flipping a fold-shaped tip portion 29 described later of the main filter 23. I have.

The main filter 23 is detachably engaged with a side surface of the dust collecting case 21 opposite to the opening by a locking piece 27. The main filter 23 is formed by arranging a non-woven fabric folded in a pleated shape on the outer periphery of a cylindrical body 28 serving as a passage of filtered air in a cylindrical shape, and the pleated tip portion 29 is made of synthetic resin. It is cured to prevent damage due to contact of the dust remover.

Reference numeral 41 denotes a connection port provided in the dust collecting case 21, which is eccentric with respect to the center of the dust collecting case 21 at a position below a front portion when the dust collecting device 20 is mounted on the cleaner body 1. It is formed at a position, and is hermetically connected to the connection port 10 of the cleaner body 1 by a packing 42 provided on the periphery. Further, the connection port 41 is provided with a valve body (not shown) which is constantly urged in a direction to close the connection port 41 and is opened only inside the dust collection case 21 so that dust and the like in the dust collection case 21 are connected. It prevents leakage from the mouth 41.

Reference numeral 43 denotes a clamp for locking the lid 24 formed at a position opposite to the position at which the handle 30 of the dust collecting case 21 is formed.

The cover 24 has a discharge port 44 formed at a substantially central portion thereof. The discharge port 44 communicates with the inside of the cylindrical body 28 of the main filter 23 and the main body of the cleaner 20 of the dust collector 20. 1
In the state of being mounted on the vacuum cleaner, the discharge port 44 is air-tightly connected to the suction port 11 of the cleaner body 1 via the packing 45.
The packing 45 provided at the outlet 44 abuts on the tubular body 28 of the main filter 23, and air that does not pass through the non-woven fabric of the main filter 23 from between the tubular body 28 and the lid 24 is supplied to the electric blower 6. It is designed to prevent it from flowing.

Reference numeral 46 denotes a recess formed in an annular shape toward the inside of the dust collecting case 21 at an outer peripheral position of the discharge port 44 of the lid 24. Is to be prevented. 47 is a packing provided on the cylindrical body 22, which abuts against the outer periphery of the concave portion 46 of the lid 24, and air that does not pass through the pre-filter 25 from between the cylindrical body 22 and the lid 24 is directed toward the main filter 23. We prevent flowing.

When a flexible hose is connected to the suction port 4 and the electric blower 6 is driven, dust sucked from the floor suction tool receives dust through the extension pipe and the flexible hose. From the dust-collecting case 21 through the dust-collecting path 12, the connection port 10, and the connection port 41, and swirls along the inner wall of the dust-collection case 21 to cover the cover 24.
The relatively large dust flows in the direction and accumulates in a compressed state from the lid 24 side.

The fine dust is removed from the pre-filter 28 together with air.
, Is filtered by the non-woven fabric of the main filter 23, and only clean air passes through the main filter 23, passes through the suction path 15, passes through the electric blower 6, and is discharged to the outside through the exhaust port 18.

When dust accumulates in the dust collecting device 20, the dust collecting device
By operating the removing operation mechanism 31 of 20, the first clamp 34 and the second clamp 37 are unlocked from the locking portions 33 and 36, and the dust collector 20 is removed from the cleaner body 1. Then, the lid 24 is opened, and the rotation handle 39 is turned to rotate the cylinder 22.

When the cylindrical body 22 rotates, the spiral body 26 provided on the outer periphery of the cylindrical body 22 acts to push out the dust inside the dust collecting case 21, and discharges the dust out of the dust collecting case 21 through the opening. Can be easily performed. Further, since the dust in the dust collection case 21 wipes the dust adhered to the outer peripheral surface of the pre-filter 25, it is possible to prevent a decrease in dust collection efficiency due to the adhesion of the dust to the pre-filter 25.

Also, the rotation of the cylinder 22 causes the dust removing body to flip the fold-shaped tip 29 of the main filter 23, and the vibration causes fine dust adhering to the non-woven fabric of the main filter 23 to be flipped off and collected from the opening. It is possible to prevent the dust collection efficiency from being reduced due to the dust being discharged to the outside of the dust case 21 and adhering to the main filter 23.

The dust collecting device storage chamber 9 of the cleaner body 1 is formed so as to become wider as it goes upward, so that the work of mounting the dust collecting device 20 to the dust collecting device storage room 9 can be easily performed. And the mounting workability can be improved. As shown in FIG. 8, when the user mistakenly tries to attach the dust collector 20 to the cleaner body 1 with the lid 24 of the dust collector 20 not completely closed, the dust collector 20 collects the dust. The lid 24 is not pressed and closed by the rear wall surface of the dust collection device storage chamber 9 as it enters the apparatus storage chamber 9, and the lid 24 does not remain open.

The dust collecting device 20 is attached to the cleaner main body 1 in an inclined state such that the opening of the dust collecting case 21 is located upward. Even when the lid 24 is opened for some reason or the like, the dust in the dust collector 20 is prevented from spilling from the opening as much as possible, in combination with the dust being accumulated in a compressed state on the lid 24 side. be able to.

When the dust collector 20 is mounted on the cleaner body 1, the outlet 44 is inclined toward the upper rear, and the electric blower 6 is mounted so that the air inlet 7 faces upward. As a result, the air can smoothly flow through the suction path 12 from the suction port 4 to the dust collector 20 and the suction path 15 from the dust collector 20 to the electric blower 6, thereby reducing the airflow resistance. Thus, the intake efficiency can be improved.

Further, since the opening of the dust collecting case 21 is gradually narrowed from the side surface on which the handle 30 is formed to the opposing side surface, the dust collecting case 21 is not greatly tilted. The opening can be made substantially parallel to the floor surface, so that dust in the dust collecting device 20 can be easily discharged.
