(concerning the operation of the vacuum cleaner main body and maintenance of the dust collecting device)
As shown in fig. 1 and 2, a flexible hose having a handle and an operation portion, not shown, an extension pipe, and a suction port body are connected to a cleaner body 1 of the vacuum cleaner of the present invention during cleaning.
When the power is turned on by the operation unit, the electric blower 30 is driven, and dust on the surface to be cleaned is sucked together with air and cleaned.
The air containing dust sucked into the suction port body is sucked into the cleaner body 1 through the extension pipe and the flexible hose.
The flow of air in the cleaner body 1 will be described below with reference to fig. 1 to 10.
Further, the flow of air becomes an arrow F in fig. 21～F10The order of (a).
The air containing dust first flows into the connection port 11b of the driving device 10 (arrow F)1) Through a first flow path 18a (arrow F) between the connection port 11b and the air outlet port 11c2) Flows into the air inlet 61c of the dust cup 60 of the dust collecting device 50 (arrow F)3)。
The air containing dust flowing into the dust cup 60 is swirled in the dust cup 60, during which time the larger dust is swirled on the inner peripheral surface side of the dust cup 60 by the centrifugal force, and the air containing fine dust is directed toward the mesh portion 74 (arrow F)4)。
Thereby, larger dust is captured into the dirt cup 60.
The particles passing through the mesh part 74The small dust-laden air flows into the cup portion 73 of the filter unit 70 (arrow F)5) The fine dust is caught by the filter main body 71, the fine dust is removed, and the purified air flows into the filter cover 80 through the filter main body 71, and is discharged from the air discharge port 81a of the filter cover 802Toward the air inlet 11d of the driving device 10 (arrow F)6)。
The cleaned air flowing into the driving device 10 passes through the second flow path 18b between the air introduction port 11d and the electric blower 30 (arrow F)7) The third flow path 18c between the electric blower 30 and the exhaust port 11e is formed by the electric blower 30 (arrow F)8Arrow F9) And is discharged to the outside from the exhaust port 11e (arrow F)10)。
Next, maintenance of the dust collecting device 50 after cleaning will be described.
The dust collection between the filter main body 71 and the mesh part 74 of the dust collecting device 50 and the compression of the dust collected in the dust cup 60 are performed simultaneously by rotating the handle part 92 of the interlocking mechanism 90 in a predetermined direction.
In this case, dust removal and compression are performed even in a state where the dust collecting device 50 is attached to the driving device 10, but it is preferable that appropriate dust removal and compression be performed in a state where the dust collecting device 50 is detached from the driving device 10 and the dust collecting device 50 is upright.
The dust removal and compression performed by detaching the dust collecting device 50 from the driving device 10 will be described below.
First, when the dust collection device 50 attached to the drive device 10 is detached, the pair of locking claws 91b of the dust collection device 50 engaged with the pair of engaging recesses 11g of the drive device 10 are swung and disengaged from the respective engaging recesses 11g by grasping and pulling the handle portion 92 of the dust collection device 50 with a hand, so that the user can detach the dust collection device 50 in one step of pulling up the handle portion 92.
The diameter of the cylindrical shape decreases downward so as to facilitate gripping of the handle main body 92a of the handle portion 92 with a hand.
Thus, the convex portion is formed so as to be easily grasped by a hand.
The dust collecting device 50 detached from the driving device 10 is placed on a stable surface such as a floor surface in an upright state, and the handle 92 is rotated in the direction of the arrow shown by the flat surface of the lid body 92b of the handle 92 (fig. 1 a).
Thereby, the interlocking mechanism 90 rotates as a whole.
That is, when the handle 92 rotates, the first coupling shaft 93, the second coupling shaft 94, and the first gear 96 coupled to the handle 92 rotate, and the second gear 191a that meshes with the first gear 96 is provided1The circular frame 191a of the dust removing unit 191 rotates, and the sliders 191b slide on the upper surface side of the pleated filter body 71 while rotating.
As a result, the filter main body 71 vibrates, and fine dust adhering to the lower surface side falls into the internal space of the screw compressor 293, thereby removing dust from the filter main body 71.
Further, the dust can be removed from the filter main body 71 without rotating the handle portion 92.
In this case, as shown in fig. 8, the locking portion 81d is pushed to disengage the locking portion 81d from the locking protrusion 73d and unlock the unit, the first unit a is opened, and the grasping piece 191a of the dust removing portion 191 is rotated3The circular frame 191a is rotated to remove dust from the filter body 71.
Thereafter, when the first unit A is closed, the first gear 96 and the second gear 191a are again engaged1And (4) occlusion.
When the circular housing 191a rotates, the third coupling shaft 192 and the plurality of protrusions 193 coupled to the circular housing 191a rotate.
As described above, the plurality of upper protrusions 291a of the inner cylindrical frame 291 contact the plurality of rotating protrusions 193, and as a result, the inner cylindrical frame 291 rotates, and the outer cylindrical frame 292 and the helical compression portion 293 connected to the inner cylindrical frame 291 rotate.
By the rotation of the outer cylindrical frame portion 292, dust adhering to the outer surface of the mesh main body 74a of the mesh portion 74 is wiped and dropped.
This removes dust from the mesh 74.
In addition, the dust accumulated at the bottom of the dust cup 60 is compressed by the spiral blade portion 293c by the rotation of the spiral compression portion 293.
At this time, the plurality of small protrusions 293c passing under the spiral blade portion 293c1Dust cake can be formed and compressed efficiently.
When a large amount of dust is accumulated in the dust cup 60 and the accumulated dust is compressed to the maximum, the screw compressor 293 may be difficult to rotate due to dust lumps, and the entire link mechanism 90 may be damaged by applying an excessive load.
Therefore, when an excessive load is applied to the interlocking mechanism 90, the plurality of protrusions 193 of the second coupling shaft 192 slide over the plurality of upper protrusions 291a of the inner cylindrical frame portion 291, and the second coupling shaft 192 of the interlocking mechanism 90 is idle-rotated to the handle portion 92. Thus, the rotational force is not transmitted to the inner cylindrical frame portion 291, the outer cylindrical frame portion 292, and the screw compressor portion 293, thereby preventing the link mechanism 90 from being damaged.
Further, the second coupling shaft 192 is idle-rotated to the handle portion 92, thereby removing dust from the filter main body 71.
Further, since the idling of the interlocking mechanism 90 causes the sound and vibration of "rattling", the user can recognize that the dust in the dust cup 60 is full and the compression operation is stopped, and can recognize the timing of discarding the dust in the dust cup 60.
When the dust in the dust cup 60 is discarded, the bottom cover 62 is opened by pressing the operation member 64c of the lock portion 64, and the dust in the dust cup 60 drops and is discarded.
The dust collecting device 50 can be disassembled and cleaned as follows.
First, as shown in fig. 9, after the dust cup 60 is detached by rotating the unit body X to which the first, second, and third units A, B, C are coupled, as shown in fig. 10, the first, second, and third units A, B, C are disassembled, and the second, third units B, C and the dust cup 60 are washed with water, respectively. At this time, since the third unit C can be further disassembled into the respective members as shown in fig. 13, each corner of the respective members can be cleaned cleanly.
Further, since the mesh portion 74 is coupled to the cup portion 73 and the screw 76 via the packing 75, the disassembly of these is not recommended.
(second embodiment)
The cleaner body of the second embodiment is configured in the same manner as the first embodiment, except that the interlocking mechanism of the dust collecting device is different from that of the first embodiment.
Hereinafter, the second embodiment is mainly described as being different from the first embodiment.
The first embodiment exemplifies a case configured as follows: when an excessive load is applied to the screw compression portion 293 of the interlocking mechanism 90, the plurality of protrusions 193 of the third coupling shaft 192 slide and run idle so as to straddle the plurality of upper protrusions 291a of the inner cylindrical frame portion 291, and therefore, breakage of the interlocking mechanism 90 is prevented.
In contrast, in the second embodiment, the structure is such that: since the first gear 96 is driven from the second gear 191a when an excessive load is applied to the helical compression part 293 of the interlocking mechanism 901Disengaged and idled, so that the link mechanism 90 is prevented from being damaged.
In this case, the first and second gears 96, 191a are designed to be1The engagement is released when a predetermined load is exceeded.
Further, the structure is: even if an excessive load is applied to the screw compression portion 293, the plurality of protrusions 193 of the third coupling shaft 192 ride over the plurality of upper protrusions 291a of the inner cylindrical frame portion 291 and do not run idle.
(third embodiment)
In the first embodiment, the case where the battery 20 is detachably attached to the drive device 10 is exemplified, but in the third embodiment, a lead shaft having a plug connectable to a commercial power supply is provided at the rear of the drive device instead of the battery.

Further, when the compression of dust reaches the limit and an excessive load is applied to the screw compression portion, the first gear of the shaft portion is disengaged from the second gear and idles, so that the interlocking mechanism can be prevented from being damaged. At this time, the user can recognize that an excessive load is applied to the screw compression portion and the compression operation is stopped by the idle rotation of the first gear.
