Next, operation | movement of the vacuum cleaner comprised as mentioned above is demonstrated.

First, as shown in FIG. 2, the dust collector 50 is disposed in the dust collecting chamber 21 of the vacuum cleaner main body 11, and the dust collecting hose 12 is connected to the main body 11 as shown in FIG. 1. The suction unit 15 is connected to the handle operating tube 13 via the extension tube 14 while being connected to the 10A.

When the drive switch 13B of the operation part 13A of the handle operation pipe 13 is operated, the electric blower 23 is driven. By driving of this electric blower 23, air is sucked in from the suction opening 24 of the electric blower 23, and suction of air is carried out through the connection air passage G, and the rear opening 51 of the dust collector 50 is carried out. ), And the negative pressure chamber 57 of the dust collector 50 becomes negative pressure through the pleated filter unit P.

This negative pressure acts on the air passage 62 of the dust separating means 60 through the filter F2 of the dust collecting chamber 55, inside the dust collecting chamber 55 and the net filter F1 of the dust separating means 60. Subsequently, this negative pressure acts on the dust collecting hose 12, the extension pipe 14, and the suction unit 15 through the suction port 52 of the dust collector 50 to suck air and dust through the suction unit 15.

The sucked dust and air are introduced into the suction port 52 of the dust collector 50 through the extension pipe 14 and the dust collecting hose 12. The dust and air sucked into the suction port 52 are sucked into the air passage 62 of the dust separating means 60.

And is introduced into the dust collection chamber 55. That is, the dust is separated from the air by the dust separating means 60, and the separated dust is collected into the dust collecting chamber 55.

In addition, the air going straight through the air passage 62 is guided by the guide wall 101 of the compression member 100 and introduced into the dust collection chamber 55. The air introduced into the dust collection chamber 55 is sucked into the negative pressure chamber 57 of the dust collector 50 by passing through the filter F2 of the rear wall 55H of the dust collection chamber 55, and of the dust collector 50. The suction opening 24 of the electric blower 23 is sucked through the pleated filter unit P and the connecting air passage G of the rear opening 51.

When cleaning is complete | finished, operation of the stop switch 13B arrange | positioned at 13 A of operation parts is stopped and the drive of the electric blower 23 is stopped. And the button 42 provided in the main body 11 is pushed down. When the button 42 is pressed downward, the lever 85 is pressed downward against the pressing force of the springs S1 and S1.

When the lever 85 is pushed downward, the compression member 100 is moved downward by the interlock mechanism 70.

When the compression member 100 is pressed downward, the blade 110 of the compression member 100 slides the filter surface F2a of the filter F2 to scrape off the dust attached to the filter surface F2a. Drop it. In addition, the dust stored in the dust collecting chamber 55 is compressed by moving the compression member 100 downward. Therefore, a large amount of dust can be accommodated in the dust collection chamber 55.

When the button 42 is released, the lever 85 returns to its original position by the pressing force of the springs S1 and S1, and together with the lever 85, the compression member 100 and the button 42 are depressed. Return to the original position shown in 2.

Next, the case where the dust stored in the dust collection chamber 55 is discarded is demonstrated.

First, the cover 40 is opened to take out the dust collector 50 from the main body 11. And when the operation part 91A shown in FIG. 4 is pressed, the bottom cover 59 will rotate to the arrow P1 direction centering on the axis J1, and will open by the opening-closing mechanism 90. FIG.

Subsequently, when the lever 85 is gripped together with the grip portion 54, the lever 85 is pressed downward toward the grip portion 54, and the compression member (by pressing the lever 85 downward) is pressed. 100 is pushed downward by the linkage mechanism 70 to a position sufficient to discharge the dust. As a result, the dust in the dust collecting chamber 55 is pushed downward from the bottom opening of the dust collector 50, so that it is easy to discard the dust.

In addition, since the compression member 100 can be attached and detached from the rods 104 and 104, it is possible to clean dust or the like on the compression member 100.

9 shows a portion of a dust collector 150 of another embodiment. The dust collector 150 is configured to rotate the compression member 200 around the shaft 201 to the position shown by the broken line by the interlock mechanism 70. Further, the filter F2 is formed in an arc shape, so that when the compression member 200 is rotated, the blade slides the filter surface F2a of the filter F2 and at the same time, the dust collecting chamber ( 55) dust is pushed out. In Fig. 9, reference numeral 202 denotes an opening.

In the above, the embodiment in the case where the dust collector according to the present invention is applied to the vacuum cleaner has been described, but the configuration of the dust collector can be applied not only to the vacuum cleaner but also to any other apparatus or device.
