[About the operation of the vacuum cleaner body and the maintenance of the dust collector]

As shown in FIGS. 1 and 2, the vacuum cleaner body 1 of the electric vacuum cleaner of the present invention is connected with a flexible hose, an extension tube, and a suction port body having a handle and an operation part (not shown) during cleaning.

When the power is turned on via the operation unit, the electric blower 30 is driven to suck air together with dust on the surface to be cleaned for cleaning. The dust-containing air sucked into the suction port body is sucked into the cleaner body 1 via the extension tube and the flexible hose.

Hereinafter, the flow of air in the cleaner body 1 will be described with reference to FIGS. 1 to 10. Furthermore, the flow of air is in the order of arrows F ₁ to F _{10 in} FIG. 2.

The air containing dust first flows into the connection port 11b (arrow F ₁ ) of the drive device 10, and flows into the dust cup of the dust collection device 50 through the first flow path 18a (arrow F ₂ ) between the connection port 11b and the air outlet 11c The air inlet 61c of 60 (arrow F ₃ ).

The dust-containing air flowing into the dust cup 60 circulates in the dust cup 60, and the larger dust circulates on the inner circumferential surface side of the dust cup 60 by centrifugal force, and the air containing fine dust faces the mesh portion 74 (arrow F ₄ ). As a result, large dust is caught in the dust cup 60.

The air containing fine dust flowing through the mesh portion 74 flows into the cup portion 73 of the filter unit 70 (arrow F ₅ ), the fine dust is captured by the filter body 71, the fine dust is removed and the cleaned air passes through the filter The main body 71 flows into the filter cover 80 from the air discharge port 81a _{2 of} the filter cover 80 toward 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 second flow path 18b (arrow F ₇ ) between the air inlet 11d and the electric blower 30, passes through the electric blower 30, passes between the electric blower 30 and the exhaust port 11e The third flow path 18c (arrow F _8, arrow F _9), is discharged to the outside (arrow F ₁₀₎ from the discharge port 11e.

Next, the maintenance of the dust collector 50 after cleaning will be described.

The dust collected in the filter body 71 and the mesh portion 74 of the dust collector 50 and the compression of the dust accumulated in the dust cup 60 are simultaneously performed by rotating the handle portion 92 of the interlocking mechanism 90 in a predetermined direction. At this time, even if the dust collecting device 50 is installed in the driving device 10, the dust collecting and compressing are performed. However, for proper dust removing and compression, the dust collecting device 50 is preferably detached from the driving device 10, and the dust collecting device 50 is upright Status.

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 collecting device 50 mounted on the driving device 10, grasp the handle portion 92 of the dust collecting device 50 with your hand and pull, thereby engaging the dust collecting part 11g of the driving device 10 with a pair of engaging recesses One of the devices 50 swings the lock claws 91b and disengages from each of the engagement recesses 11g, so that the user can detach the dust collector 50 by one step of pulling up the handle 92. The diameter of the cylindrical shape is reduced downward so that the handle body 92a of the handle portion 92 can be easily grasped by hand. With this, the convex portion is formed so as to be easily grasped by hand.

Place the dust collector 50 detached from the drive device 10 in an upright position on a stable surface such as the ground, and rotate the handle 92 in the direction of the arrow shown on the flat surface of the lid 92b of the handle 92 (FIG. 1 ( A)). As a result, the entire interlocking mechanism 90 rotates.

In other words, by rotating the handle 92, the first coupling shaft 93, the second coupling shaft 94, and the first gear 96 connected to the handle 92 rotate, and the second gear 191a ₁ engaged with the first gear 96 rotates. The circular frame 191a of the dust removing portion 191 rotates, and each sliding member 191b rotates and slides to the upper surface side of the folded filter body 71 while rotating.

As a result, the filter body 71 vibrates, and fine dust adhering to the lower surface falls to the internal space of the spiral compression part 293, and the filter body 71 is dedusted.

Furthermore, the filter body 71 can be dedusted without turning the handle 92. In this case, as shown in FIG. 8, pressing the locking portion 81d to detach the locking portion 81d from the locking convex portion 73d and unlock it, open the first unit A, and rotate the grasping member 191a _{3 of the} dust removing portion 191, thereby rotating the circular shape The housing 191a removes dust from the filter body 71. After that, if the first unit A is closed, the first gear 96 will again engage with the second gear 191a ₁ .

When the circular frame 191a rotates, the third coupling shaft 192 and the plurality of protrusions 193 connected to the circular frame 191a rotate. In this way, the plurality of upper protrusions 291a of the inner cylindrical frame portion 291 resist the plurality of rotating protrusions 193, whereby the inner cylindrical frame portion 291 rotates and the outer cylindrical frame portion connected to the inner cylindrical frame portion 291 292 and the spiral compression part 293 rotate.

By rotating the outer cylindrical frame portion 292, the dust adhering to the outer surface of the mesh body 74a of the mesh portion 74 is wiped and dropped. By this, dust removal of the mesh section 74 is performed.

Further, by the rotation of the spiral compression portion 293, the dust accumulated in the bottom of the dust cup 60 is compressed by the spiral blade portion 293c. At this time, the small protrusions 293c ₁ below the spiral blade portion 293c can form a dust block and be effectively compressed.

If 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 block, and the entire interlocking mechanism 90 may be damaged due to excessive load. Therefore, if an excessive load is applied to the interlocking mechanism 90, there will be as many second connecting shafts 192 as possible The two protrusions 193 are slidably connected across the plurality of upper protrusions 291a of the inner cylindrical frame portion 291, and the space between the second coupling shaft 192 and the handle portion 92 in the interlocking mechanism 90 is idling.

As a result, the rotational force is not transmitted to the inner cylindrical frame portion 291, the outer cylindrical frame portion 292, and the spiral compression portion 293, preventing damage to the interlocking mechanism 90. In addition, the space between the second coupling shaft 192 and the handle portion 92 is idling to perform dust removal of the filter body 71.

In addition, the idling of the interlocking mechanism 90 as described above will produce a "clapping" sound and vibration, so that the user can recognize that the dust in the dust cup 60 is full and stop the compression operation, and can make the user recognize The time to discard the dust in the dust cup 60.

When discarding the dust in the dust cup 60, the bottom cover 62 is opened by pressing the operating member 64c of the lock part 64, and the dust in the dust cup 60 falls and is discarded.

In addition, the dust collector 50 can be decomposed and washed as follows.

First, as shown in FIG. 9, after the unit cup X combined with the first, second, and third units A, B, and C rotates the dust cup 60 and is removed, as shown in FIG. 10, the first, second And the third units A, B, and C are decomposed, 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 decomposed into each member, so that each member can be cleanly cleaned to each corner. Furthermore, since the mesh portion 74 is the filler 75 and is coupled to the screw 76 by the cup portion 73, such decomposition is not recommended.

(Embodiment 2)

The vacuum cleaner 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 the first embodiment.

In the following, the differences between Embodiment 2 and Embodiment 1 are mainly explained.

The first embodiment exemplifies the case where the excessive compression is applied to the helical compression portion 293 of the interlocking mechanism 90, and the plurality of protrusions 193 of the third coupling shaft 192 cross over The plurality of upper protrusions 291a of the side cylindrical frame portion 291 are slidably connected and idle, thereby preventing the damage of the interlocking mechanism 90.

On the other hand, in the second embodiment, it is configured such that if an excessive load is applied to the screw compression portion 293 of the interlocking mechanism 90, the first gear 96 is detached from the second gear 191a ₁ and is idling, thus preventing the interlocking mechanism 90 from damage. In this case, the first and second gears 96 and 191a _{1 are} designed to be disengaged when they are above a predetermined load. In addition, the configuration is as follows: even if an excessive load is applied to the spiral compression portion 293, the plurality of protrusions 193 of the third coupling shaft 192 will cross the plurality of upper protrusions 291a of the inner cylindrical frame portion 291 without idling.

(Embodiment 3)
