 Next, an operation of the vacuum cleaner configured as described above will be described.

First, as shown in FIG. 2, the dust container 50 is mounted in the dust container chamber 21 of the cleaner body 11, and the dust collection hose 12 is connected to the connection port 10A of the cleaner body 11 as shown in FIG. The suction port body 15 is connected to the operation pipe 13 via the extension pipe 14.

When the drive switch 13B of the operation section 13A of the hand operation pipe 13 is operated, the electric blower 23 is driven. By driving the electric blower 23, air is sucked from the suction opening 24 of the electric blower 23, acts on the rear opening 51 of the dust container 50 through the connection air passage G, and furthermore, the pleated filter body P The negative pressure in the negative pressure chamber 57 of the dust container 50 becomes negative.

[0054] This negative pressure acts on the air passage 62 of the dust separation 60 through the filter F2 of the dust collection chamber 55 and the inside of the dust collection chamber 55 and the net filter F1 of the dust separation unit 60. Acts on the dust collection hose 12, the extension pipe 14, and the suction port body 15 through the suction port 52 of the dust collection container 50, and the dust is sucked from the suction port body 15 together with air. The sucked dust and air are sucked into the suction port 52 of the dust collecting container 50 via 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 section 60.

 A part of the air sucked into the air passage 62 is sucked into the negative pressure chamber 57 of the dust collecting container 50 via the net filter F1 of the dust separating unit 60, and is further pleated at the rear opening 51 of the dust collecting container 50. The air is sucked into the suction opening 24 of the electric blower 23 through the filter body P and the connection air path G.

On the other hand, the dust sucked into the air passage 62 of the dust separating unit 60 travels straight through the air passage 62 because it has more mass than the air, and is guided by the guide wall portion 101 of the compression member 100 to be collected. It is introduced into the dust chamber 55. That is, air and dust are separated by the dust separating unit 60, and the separated dust is collected in the dust collecting chamber 55.

 The air that has traveled straight through the air passage 62 is guided by the guide wall 101 of the compression member 100 and is introduced into the dust collection chamber 55. The air introduced into the dust collecting chamber 55 is sucked into the negative pressure chamber 57 of the dust collecting vessel 50 through the filter F2 of the rear wall 55H of the dust collecting chamber 55, and further, the rear opening of the dust collecting vessel 50. The air is sucked into the suction opening 24 of the electric blower 23 through the pleated filter body P and the connection air passage G of 51.

To remove dust adhering to the filter surface F2a. Go. Further, the dust accumulated in the dust collection chamber 55 is compressed by pushing down the compression member 100. Therefore, a large amount of dust can be accumulated in the dust collection chamber 55.

[0062] When the button 42 is released, the lever 85 returns to the original position by the biasing force of the springs S1 and S1, and the compression member 100 and the button 42 are moved together with the lever 85 as shown in FIG. Return to the position.

 Next, a case where the dust accumulated in the dust collection chamber 55 is discarded will be described.

First, the lid 40 of the cleaner body 11 is opened and the dust container 50 is taken out. Then, when the operation unit 91A shown in FIG. 4 is pressed, the bottom cover 59 is rotated about the shaft 1 in the direction of arrow P1 by the opening / closing mechanism 90 to be opened.

Next, when the lever 85 is squeezed together with the grip portion 54, the lever 85 is pushed down toward the grip portion 54, and when the lever 85 is pushed down, the compression member 100 discharges dust by the interlocking mechanism 70. It is pushed down to a sufficient position. As a result, the dust in the dust collecting chamber 55 is pushed downward from the bottom opening of the dust collecting container 50, so that the dust can be easily discarded.

 [0066] Further, since the compression member 100 can be removed from the rods 104, 104, dust or the like that has entered the compression member 100 can be cleaned.

 FIG. 9 shows a part of a dust container 150 of another example. The dust collection container 150 is configured such that the compression member 200 is rotated around the axis 201 by the interlocking mechanism 70 to a position indicated by a chain line. In addition, the filter F2 is formed in an arc shape, and when the compression member 200 is rotated, the blade slides on the filter surface F2a of the filter F2 so that the filter slides in contact with the filter surface. The dust of the part 55 is pushed out. In FIG. 9, reference numeral 202 denotes an opening.
