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

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

  And if the switch 13a of the operation part 13A of the hand operation tube 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 collecting container 50 via the connection air passage G, and further collects via the pleated filter body P. The negative pressure chamber 57 of the dust container 50 becomes negative pressure.

  The 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 dust filter 60 via the net filter F1 of the dust separation unit 60. The dust 50 acts on the dust collecting hose 12, the extension pipe 14 and the suction port body 15 through the suction port 52 of the container 50, and dust is sucked together with air from the suction port body 15.

  The sucked dust and air are sucked into the suction port 52 of the dust collecting container 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 separation unit 60.

  Part of the air sucked into the air passage 62 is sucked into the negative pressure chamber 57 of the dust collecting container 50 through the net filter F1 of the dust separating section 60, and further, the pleated filter body P in the rear opening 51 of the dust collecting container 50. Then, the air is sucked into the suction opening 24 of the electric blower 23 through the connection air passage G.

  On the other hand, the dust sucked into the air passage 62 of the dust separator 60 travels straight through the air passage 62 due to its mass rather than the air, and is guided by the guide wall portion 101 of the extrusion plate 100 to be collected in the dust collecting chamber. It will be introduced into 55. That is, air and dust are separated by the dust separation unit 60, and the separated dust is collected in the dust collection chamber 55.

  Further, the air that has traveled straight through the air passage 62 is guided by the guide wall portion 101 of the extrusion plate 100 and introduced into the dust collection chamber portion 55. The air introduced into the dust collection chamber 55 is sucked into the negative pressure chamber 57 of the dust collection container 50 through the filter F2 on the rear wall 55H of the dust collection chamber 55, and further the rear opening 51 of the dust collection container 50. Then, 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.

  When cleaning is completed, the switch 13a of the operation unit 13A is operated to stop driving the electric blower 23. And the button 42 of the cleaner body 11 is pushed downward. When the button 42 is pushed downward, the lever 85 is pushed downward against the urging force of the springs S1 and S1, as shown in FIGS.

  When the lever 85 is pushed down, the pushing plate 100 is pushed down by the interlocking mechanism 70.

  When the extruded plate 100 is pushed downward, the blade 110 of the extruded plate 100 is brought into sliding contact with the filter surface F2a of the filter F2, and the dust adhering to the filter surface F2a is scraped off. Further, the dust accumulated in the dust collection chamber 55 is compressed by the push-down of the push-out plate 100. For this reason, a large amount of dust can be stored in the dust collection chamber 55.

  When the hand is released from the button 42, the lever 85 returns to the original position by the urging force of the springs S1, S1, and the push plate 100 and the button 42 return to the original position shown in FIG.

  Next, the case where the dust collected 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 collecting container 50 is taken out. Then, when the operation unit 91A shown in FIG. 6 is pressed, the bottom cover 59 is rotated by the opening / closing mechanism 90 in the direction of the arrow P1 about the axis line J1 to be opened.

  Next, when the lever 85 is clamped together with the grip portion 54, the lever 85 is pushed down toward the grip portion 54 as shown in FIG. 23, and by the depression of the lever 85, as shown in FIG. The extruded plate 100 is pushed down to a position sufficient for discharging dust. 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 it is easy to throw away the dust.

  If the dust collection container 50 is forgotten to be installed in the dust collection container chamber 21 of the cleaner body 11, the suction opening 24 of the electric blower 23 and the dust collection container chamber 21 of the cleaner body 11 are directly connected via the guide air path G. Communicated. And if the switch 13a of the operation part 13A of the hand operation tube 13 is operated, the electric blower 23 is driven and the dust collection container chamber 21 becomes negative pressure.

  Due to this negative pressure, as shown in FIG. 4, the button 42 of the lid 40 is pushed downward against the urging force of a spring (not shown), and the hole 41 of the lid 40 is opened. Thereby, outside air is introduced into the dust collecting container chamber 21 of the cleaner body 11 through the hole 41, and almost no dust is sucked from the suction port body 15. That is, the dust is prevented from being sucked from the suction port body 15.

  For this reason, the malfunction that the dust attracted | sucked from the suction inlet 15 is attracted | sucked directly in the electric blower 23 can be prevented. Moreover, when the secondary filter (not shown) is installed in the upstream of the electric blower 23, it is prevented that the secondary filter is clogged immediately. Further, it is possible to prevent a problem that the suction port body 15 sucks hard foreign matter and the foreign matter breaks the secondary filter and is sucked into the electric blower 23 to break the electric blower 23.

  Further, since the extruded plate 100 can be removed from the rods 104, 104, dust or the like that has entered the extruded plate 100 can be cleaned.

  FIG. 24 shows a part of another example of the dust collecting container 150. The dust collecting container 150 is configured such that the push-out plate 200 is rotated around the axis 201 to the position indicated by the chain line by the interlocking mechanism 70. Further, when the filter F2 is formed in an arc shape and the push plate 200 is rotated, the blade (dust removing means) 110 is brought into sliding contact with the filter surface F2a of the filter F2, and the push plate 200 collects dust. The dust in the chamber 55 is pushed out. Reference numeral 202 denotes an opening.

  By the way, the negative pressure in the dust collecting container chamber 21 moves the button 42 of the lid 40 downward to open the hole 41. The magnitude of the biasing force of a spring (not shown) that biases the button 42 is predetermined. By setting the value, the button 42 can be vibrated in the up and down direction. The notification sound may be generated by the vibration of the button 42. In this case, the button 42 and the spring constitute the notification means.

  Further, a vibration member (warning member) that vibrates and generates sound when outside air flows through the hole 41 may be provided in the hole 41 to warn of forgetting to attach the dust collection containers 50 and 150. Good.

  In the above-described embodiment, the dust in the dust collection chamber 55 is pushed out by the extrusion plates 100 and 200, but the dust may not be pushed out. That is, the extrusion plates 100 and 200 may be for removing dust adhering to the filter F1 with the blade 110. In this case, the extrusion plate 100 (200), the blade 110, and the interlocking mechanism 70 constitute dust removing means. In this case, the button 42 is a dedicated button for operating the dust removing means.
