[Operation of vacuum cleaner and maintenance of dust collector]
As shown in FIG. 1, the vacuum cleaner main body 1 of the vacuum cleaner provided with the dust collector 20 of the present invention has a flexible hose, an extension pipe, and a suction port body having a handle and an operation unit (not shown) at the time of cleaning. Connected.
When the power source is turned on at the operation unit, the electric blower 30 is driven and the dust on the surface to be cleaned is sucked together with the air to be cleaned. Air containing dust sucked into the suction port is sucked into the cleaner body 1 through the extension pipe and the flexible hose.

Hereinafter, the flow of air in the cleaner body 1 will be described with reference to FIGS. The air flow is in the order of arrows F _{1 to} F ₁₀ in FIG.
The air containing dust first flows into the connection port 11b of the drive device 10 (arrow F ₁ ), passes through the first flow path 17a between the connection port 11b and the air outlet port 11c (arrow F ₂ ), and collects dust. It flows into the air inlet 21a ₂ of the dust cup 21 of the apparatus 20 (arrow F ₃ ).

The air containing the dust flowing into the dust cup 21 swirls in the dust cup 21, and the relatively large first dust swirls on the inner peripheral surface side of the dust cup 21 by centrifugal force, and fine dust is collected. The contained air goes to the mesh member 22Aa ₁₁₁ (arrow F ₄ ). As a result, relatively large first dust accumulates in the first dust collecting chamber 21 </ b> R in the dust cup 21.

Air containing second dust that is finer than the first dust that has passed through the mesh portion 22Aa ₁₁₁ flows into the cylindrical portion 22Aa of the first centrifugal separation portion 22A (arrow F ₅ ), and the second centrifugal separation portion 22B. It flows into the air flow hole 22Bb _2. Then, air containing the second dust flows from a plurality of air inlet holes 22Ba ₁₂₁ into the interior of a plurality of centrifuge tube 22Ba, the inner peripheral surface of the outer tubular portion 22Ba ₁₂ of the double cylinder portion 22Ba ₁ and each It swirls along the inner circumferential surface of the tapered tube portion 22Bb _1.

When the air containing the second dust is swung along the inner peripheral surfaces of the plurality of tapered cylindrical portions 22Bb ₁ , the second dust is centrifuged and a plurality of second dust collections partitioned in the centrifuge unit 22 are obtained. It collects in the chamber 22R. On the other hand, the air from which the second dust has been removed passes through the inside (arrow F ₆ ) of the inner cylinder part 22Ba ₁₁ of the plurality of double cylinder parts 22Ba ₁ from the upper end opening 22Ba ₁₁₁ to the cover body of the rotating part 22D. It flows into 22Da ₁ , passes through the filter 50 of the driving device 10 from the air discharge port 22Da ₁₂ and flows into the air introduction port 11d (arrow F ₇ ).

The cleaned air flowing into the drive device 10 passes through the third flow path 17b between the air inlet 11d and the electric blower 30, passes through the electric blower 30, the electric blower 30 and the exhaust port 11e ₁ Is passed through the third flow path 17c (arrows F ₈ and F ₉ ) and discharged to the outside through the exhaust port 11e ₁ (arrow F ₁₀ ).

Next, the maintenance of the dust collector 20 after cleaning will be described.
Compression of dust removal and a first dust accumulated in the first dust collecting chamber 21R of the dust cup 21 of the mesh member 22Aa ₁₁₁ of the dust collecting device 20, at the same time by turning the handle 22Dc ₁ of the rotational portion 22D in a predetermined direction Done. At this time, dust removal and compression can be performed even when the dust collector 20 remains attached to the drive device 10, but appropriate dust removal and compression can be performed by removing the dust collector 20 from the drive device 10. It is desirable to carry out with 20 set up.
Hereinafter, dust removal and compression performed by removing the dust collector 20 from the drive device 10 will be described.

First, when removing the dust collecting device 20 mounted on the drive 10, by pulling grip the handle 22Dc ₁ of the dust collecting device 20 by hand, engaged with the pair of engaging recesses 11g of the driving device 10 collecting since the pair of locking claws 22Db ₂ of dust 20 is disengaged by swinging from the engagement recess 11g, the user can detach the dust collecting device 20 with operation of one step of pulling a handle 22Dc _1. The handle 22Dc ₁ has a cylindrical diameter that becomes smaller toward the bottom so that the handle body 22Dc ₁₁ can be easily grasped by hand.

The dust collecting device 20 is detached from the drive 10, is placed in an upright state on a stable surface such as a floor surface, the arrow direction (clockwise shown in the flat surface of the lid 22Dc ₁₂ of the handle 22Dc ₁ turn the handle 22Dc ₁ in the direction). As a result, the rotational force transmission frame body 22Aa ₃ and the compression screw portion 22Aa ₂ of the inner cylinder portion 22Aa rotate.
More specifically, when the handle 22Dc ₁ rotates, the first connecting shaft 22Dc ₃ , the second connecting shaft 22Dc ₄ and the first gear 22Dc ₂ connected to the handle 22Dc ₁ are moved in the direction of the arrow Q1 shown in FIG. The second centrifugal separator 22B having the second gear 22Ba ₄ that rotates forward and meshes with the first gear 22Dc ₂ also rotates forward in the direction of the arrow Q1 shown in FIG.

By the second centrifugation unit 22B rotates, a plurality a plurality of turning force transmitting pawl 22Bc ₂ is rotated in the second centrifugal separator unit 22B, in contact with a plurality of rotating force transmission claw 22Bc ₂ of the first centrifugal separator unit 22A those The rotating screw transmission frame 22Aa ₃ having the receiving claws 22Aa ₃₂ rotates, and the compression screw portion has a plurality of receiving claws 22Aa ₂₅ that come into contact with the rotating force transmission claws 22Aa _{33 of} the rotating rotating power transmission frame 22Aa _3. 22Aa ₂ is rotated.

At this time, by the outer frame portion 22Aa ₂₁ of the compression screw portion 22Aa ₂ rotates, dust is performed wiped the dust attached to the outer surface of the mesh member 22Aa _111.
Further, the spiral blade 22Aa ₂₄ of the compression screw portion 22Aa ₂ is by rotating, a first dust accumulated in the bottom of the first dust collecting chamber 21R of the dust cup 21 is compressed by the spiral blade 22Aa _24. At this time, a dust lump can be formed by the plurality of small protrusions 22Aa ₂₄₁ on the lower surface of the spiral blade 22Aa ₂₄ and effectively compressed.

Accumulate a large amount of the first dust within the dust cup 21, the first dust that accumulates is compressed to the limit, it becomes difficult to rotate the compression screw portion 22Aa ₂ by mass of the first dust, turning part 22Dc, the second centrifuge 22B, etc. may be overloaded and damaged. Therefore, when an overload is applied to the rotation mechanism portion 22Dc, the second centrifuge portion 22B, etc., the plurality of rotational power transmission claws 22Bc _{2 of} the second centrifugal separation portion 22B become the plurality of receiving claws of the rotational power transmission frame body 22Aa _3. The rotating mechanism 22Dc and the second centrifugal separator 22B are idled so as to slide over the 22Aa ₃₂ . Further, the first gear 22Dc ₂ may idle with respect to the second gear 22Ba ₄ .
As a result, the rotational force is not transmitted to the rotating power transmission frame body 22Aa ₃ and the compression screw portion 22Aa ₂ , and damage to the rotation mechanism portion 22Dc, the second centrifugal separation portion 22B, and the like is prevented.

Further, since the idle rotation of the rotation mechanism portion 22Dc and the second centrifugal separation portion 22B as described above generates a sound and vibration such as “rattle”, it is assumed that the first dust in the dust cup 21 is full. And the compression operation can be stopped, and the user can recognize that it is time to discard the first dust in the dust cup 21.
Dispose of first dust in the dust cup 21, open bottom 21b by pressing the lock release button 21c ₁ of the locking portion 21c, the first dust in the dust cup 21 is dropped and falls ( 8 and 9).

In this case, depressed first centrifugation unit 22A by a plurality of compression springs 22y, mass of the first dust so as to be dragged by the compression screw portion 22Aa ₂ falls. Therefore, even if the mass of the first dust collected in the narrow space between the dust cup 21 and the compression screw portion 22Aa ₂ falls smoothly.

Moreover this time, since the first centrifugation portion 22A is lowered, the shutter member 22Aa ₄ is lowered for communicating with the interior of the plurality of second dust collecting chambers 22R inner cylinder portion 22Aa, in each of the second dust collection chamber 22R The second dust accumulated in the water drops through the inside of the inner cylinder portion 22Aa and is discarded. At this time, since there is a case where the second dust remains in the plurality of second dust collecting chamber 22R, by rotating the wiper portion 22C together with the second centrifugally separating part 22B by turning the handle 22Dc _1, a plurality of wipers pieces 22C ₃ can scrape off the second dust toward the inner cylinder portion 22Aa and remove it cleanly.

At this time, the plurality of wipers pieces 22C _3, thinner than the thickness of the base end portion 22C ₃₁ thickness of their tip 22C ₃₂ is, to close contact with the inner surface of the tapered portion 22Ab ₁₂ is a bottom of the cup portion 22Ab The tip 22C ₃₂ of the wiper piece 22C ₃ is easily bent (FIG. 16). Further, the plurality of wiper pieces 22C ₃ are inclined at a predetermined angle with respect to the radial direction centered on the axis so as to easily scrape off the second dust (FIG. 15), and are dropped into the inner cylindrical portion 22Aa. and the second dust is discarded and falls from the inside of the lower tubular portion 22Aa ₂₂ of the compression screw portion 22Aa _2.

Further, by turning the handle 22Dc _1, a plurality of rotational force transmission pawl 22 bc ₂ is in contact with a plurality of receiving claws 22Aa ₃₂ of the rotational force transmitting frame 22Aa ₃ by the rotation of the second centrifugal separator unit 22B, the rotational force the transmission pawl 22Bc ₂ slidably contacts the inclined surface 22Aa ₃₂₁ of the receiving claws 22Aa _32. Thereby, for example, even if the second dust is clogged in the gap between the shutter member 22Aa ₄ and the inner peripheral surface of the insertion hole of the upper cup 22Ab ₁ , it is difficult to lower the shutter member 22Aa _4. pawl 22Bc ₂ is the rotational force transmitting frame 22Aa ₃ forcibly pushed lowered by sliding contact with the inclined surface 22Aa ₃₂₁ of the receiving claws 22Aa _32, the shutter together with the intermediate tubular member 22Aa ₁ which receives a rotational force transmitting frame 22Aa ₃ The member 22Aa ₄ is pushed down, and each second dust collection chamber 22R communicates with the inside of the inner cylinder portion 22Aa.

Thus, cleaning of the in conjunction with the rotation of the handle 22Dc ₁ in the second dust collecting chamber 22R by the rotation of the downward movement and the wiper portion 22C of the shutter members 22Aa ₄ is performed, the same outer frame compression screw portion 22Aa ₂ simultaneously parts 22Aa ₂₁ is removed of dust that again by the mesh member 22Aa ₁₁ to rotate, and the discharge of the first dust mass by the downward movement of the compression screw portion 22Aa ₂ is performed.
Further, as described with reference to FIG. 19B, by rotating the handle 22Dc1 in the reverse direction, the first gear 22Dc2 is rotated in the reverse direction of the arrow Q2, thereby causing the first gear to slide on the second gear 22Ba4. Then, vibration may be generated thereby to remove dust remaining in the second dust collection chamber 22R and the first dust collection chamber 21R.

As shown in FIGS. 9 and 10, the dust collector 20 can be decomposed into a dust cup 21, a first centrifugal separator 22A, a second centrifugal separator 22b, and a rotating part 22d, and the first centrifugal separator 22A. Can be disassembled into an assembly of the intermediate cylinder member 22Aa ₁ and the shutter member 22Aa ₄ , the rotational power transmission frame body 22Aa _3, and the compression screw portion 22Aa ₂ .
