[About the operation of the vacuum cleaner and the maintenance of the dust collector]
As shown in FIGS. 1 and 2, the vacuum cleaner body 1 of the vacuum cleaner of the present invention is connected to a flexible hose having a handle and an operation portion (not shown), an extension pipe, and a suction port during cleaning.
When the power is turned on in the operation unit, the electric blower 30 is driven to suck dust on the surface to be cleaned together with air for cleaning. The air containing dust sucked into the suction port body is sucked into the vacuum cleaner main body 1 through the extension pipe and the flexible hose.

Hereinafter, the air flow in the vacuum cleaner main body 1 will be described with reference to FIGS. 1 to 10. 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 18a between the connection port 11b and the air outlet 11c (arrow F ₂ ), and collects dust. It flows into the air inlet 61c of the dust cup 60 of the device 50 (arrow F ₃ ).

The air containing dust that has flowed into the dust cup 60 swirls in the dust cup 60, and during this period, relatively large dust swirls on the inner peripheral surface side of the dust cup 60 due to centrifugal force, and the air containing fine dust swirls. Heading toward the mesh portion 74 (arrow F ₄ ). As a result, relatively large dust is trapped in the dust cup 60.

The air containing fine dust that has passed through the mesh portion 74 flows into the cup portion 73 of the filter unit 70 (arrow F ₅ ), and the fine dust is captured by the filter body 71, and the fine dust is removed and cleaned. The converted air passes through the filter main body 71 and flows into the filter cover 80, _{and heads from the air discharge port 81a 2} of the filter cover 80 to the air introduction port 11d of the drive device 10 (arrow F ₆ ).

The cleaned air flowing into the drive device 10 passes through the third flow path 18b between the air inlet 11d and the electric blower 30 (arrow F _7), passes through the electric blower 30, the electric blower 30 It passes through the third distribution path 18c between the exhaust port 11e (arrows F ₈ and F ₉ ) and is discharged to the outside from the exhaust port 11e (arrow F ₁₀ ).

Next, maintenance of the dust collector 50 after cleaning will be described.
Dust removal from the filter main body 71 and the mesh portion 74 of the dust collector 50 and compression of the dust accumulated in the dust cup 60 are performed at the same time by turning the handle portion 92 of the interlocking mechanism 90 in a predetermined direction. At this time, dust removal and compression are performed even when the dust collector 50 is attached to the drive device 10, but proper dust removal and compression is performed by removing the dust collector 50 from the drive device 10 and removing the dust collector 50. It is desirable to do it in an upright position.
Hereinafter, dust removal and compression performed by removing the dust collector 50 from the drive device 10 will be described.

First, when removing the dust collector 50 mounted on the drive device 10, the handle portion 92 of the dust collector 50 is grasped by hand and pulled to collect the dust collector engaged with the pair of engaging recesses 11g of the drive device 10. Since the pair of lock claws 91b of the dust device 50 swing to separate from each engaging recess 11g, the user can remove the dust collector 50 by a one-step operation of pulling up the handle portion 92. The diameter of the cylindrical shape decreases downward so that the handle body 92a of the handle portion 92 can be easily grasped by hand. As a result, a convex portion is formed so that it can be easily grasped by hand.

The dust collector 50 removed from the drive device 10 is placed upright on a stable surface such as a floor surface, and the handle portion 92 is placed in the direction of the arrow indicated on the flat surface of the lid 92b of the handle portion 92. (Fig. 1 (A)). As a result, the entire interlocking mechanism 90 rotates.
That is, as the handle portion 92 rotates, the first connecting shaft 93, the second connecting shaft 94, and the first gear 96 that are connected to the handle portion 92 rotate, and the second gear 191a ₁ that meshes with the first gear 96 is moved. The circular frame 191a of the dust removing portion 191 is rotated, and each sliding connector 191b is rotated to slide the upper surface side of the pleated filter main body 71.

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 spiral compression portion 293, and the dust of the filter main body 71 is removed.
It is also possible to remove dust from the filter body 71 without turning the handle portion 92. In this case, as shown in FIG. 8, the lock portion 81d is pushed to release the lock portion 81d from the locking convex portion 73d to release the lock, the first unit A is opened, and the knob 191a ₃ of the dust removing portion 191 is turned. The circular frame 191a is turned to remove dust from the filter body 71. After that, when the first unit A is closed, the first gear 96 meshes with _{the second gear 191a 1 again.}

As the circular frame body 191a rotates, the third connecting shaft 192 connected to the circular frame body 191a and the plurality of protrusions 193 rotate. Then, the plurality of upper protrusions 291a of the inner cylindrical frame portion 291 abut on the plurality of rotating protrusions 193, whereby the inner cylindrical frame portion 291 rotates, and the outer cylindrical frame portion 292 and the outer cylindrical frame portion 292 connected to the inner cylindrical frame portion 291 and The spiral compression unit 293 rotates.
As the outer cylindrical frame portion 292 rotates, the dust adhering to the outer surface of the mesh main body 74a of the mesh portion 74 is wiped off and dropped. As a result, the mesh portion 74 is dust-removed.
Further, as the spiral compression portion 293 rotates, the dust accumulated at the bottom of the dust cup 60 is compressed by the spiral blade portion 293c. At this time, a plurality of small protrusions 293c1 on the lower surface of the spiral blade portion 293c can form a mass of dust and effectively compress it.

When a large amount of dust accumulates in the dust cup 60 and the accumulated dust is compressed to the limit, the spiral compression portion 293 becomes difficult to rotate due to the dust mass, and the entire interlocking mechanism 90 may be overloaded and damaged. be. Therefore, when the interlocking mechanism 90 is overloaded, the plurality of protrusions 193 of the second connecting shaft 192 slide into contact with each other so as to get over the plurality of upper protrusions 291a of the inner cylindrical frame portion 291. The space between the portion 192 and the handle portion 92 is designed to idle.
As a result, the rotational force is not transmitted to the inner cylindrical frame portion 291 and the outer cylindrical frame portion 292 and the spiral compression portion 293, and the interlocking mechanism 90 is prevented from being damaged. The filter main body 71 is dust-removed by idling between the second connecting shaft portion 192 and the handle portion 92.

Further, since the idling of the interlocking mechanism 90 as described above generates a rattling sound and vibration, it is possible to make the user recognize that the dust in the dust cup 60 is full and stop the compression operation. , The user can be made aware that it is time to dispose of the dust in the dust cup 60.
When discarding the dust in the dust cup 60, the bottom lid portion 62 is opened by pushing the operating member 64c of the lock portion 64, and the dust in the dust cup 60 falls and is discarded.

Further, the dust collector 50 can be disassembled and cleaned as follows.
First, as shown in FIG. 9, after removing the dust cup 60 from the unit body X to which the first, second and third units A, B and C are bonded by turning the dust cup 60, as shown in FIG. The second and third units A, B, and C are disassembled, and the second and third units B, C, and the dust cup 60 are washed with water, respectively.
At this time, as shown in FIG. 13, the third unit C can be further disassembled into individual parts, so that each component can be cleaned to every corner. Since the mesh portion 74 is connected to the cup portion 73 with the screw 76 via the packing 75, disassembly of these is not recommended.

The vacuum cleaner main body of the second embodiment is configured in the same manner as the first embodiment except that the interlocking mechanism of the dust collector is different from that of the first embodiment.
Hereinafter, the points different from the first embodiment in the second embodiment will be mainly described.

In the first embodiment, when the spiral compression portion 293 of the interlocking mechanism 90 is overloaded, the plurality of protrusions 193 of the third connecting shaft 192 are slidably contacted so as to get over the plurality of upper protrusions 291a of the inner cylindrical frame portion 291. An example is shown in which the interlocking mechanism 90 is configured to prevent damage due to idling.

On the other hand, in the second embodiment, when the spiral compression portion 293 of the interlocking mechanism 90 is overloaded, _{the first gear 96 disengages from the second gear 191a 1} and runs idle, so that the interlocking mechanism 90 is prevented from being damaged. Is configured to. In this case, the first and second gears 96 and 191a ₁ are designed so that they are disengaged when a predetermined load or more is applied. Further, even if the spiral compression portion 293 is overloaded, the plurality of protrusions 193 of the third connecting shaft 192 are configured so as not to slip over the plurality of upper protrusions 291a of the inner cylindrical frame portion 291.
