The pressing portion 521 of the dust collecting container 410 disposed at the regular storage position shown in the figure. It is formed at a position that contacts the upper surface of the handle portion 75 and a protruding amount.

  The pressing portion 521 is formed longer than the length of the handle portion 75 in the front-rear direction. This is because the pressing portion 521 is brought into contact with the upper surface of the handle portion 75 even when the dust collecting container 410 is disposed in the pop-up position as shown in FIG.

  That is, as described above, the lid case 500 is supported so as to be rotatable around the cylindrical axle 17 at the lower part of the vacuum cleaner 10, and the pressing portion 521 has a rotational trajectory around the cylindrical axle 17. Moving. On the other hand, the dust collecting container 410 moves in the vertical direction.

  For this reason, on the rotation trajectory of the lid case 500, a position overlapping the upper surface of the handle portion 75 of the dust collection container 410 disposed at the regular storage position and a handle portion 75 of the dust collection container 410 disposed at the pop-up position. The position overlapping the upper surface differs in the front-rear direction of the vacuum cleaner 10. Therefore, the pressing portion 521 has a length in the front-rear direction that reliably contacts the upper surface of the handle portion 75 at both the normal storage position and the pop-up position.

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

  First, as shown in FIG. 2, the dust collection unit 50 is mounted in the dust collection unit chamber 22 of the cleaner body 11, and the dust collection hose 12 is connected to the connection port 11 </ b> A of the cleaner body 11 as shown in FIG. 1. At the same time, the suction port body 15 is connected to the hand operation tube 13 via the extension tube 14.

  When the strength switch 13b of the operation unit 13A of the hand operation tube 13 is operated, the electric blower 24 is driven. By driving the electric blower 24, air is sucked from the suction opening 24 </ b> A of the electric blower 24, a negative pressure acts in the storage case 81 of the dust collection unit 50 through a connection air passage portion (not shown), and the suction wind It acts on the inside of the dust collection case 74 and the separation chamber portion 54 of the dust separation portion 52 via the passage portion 56. The negative pressure acts on the dust collecting hose 12, the extension pipe 14 and the suction port body 15 via the guide air duct tube 57, and dust is sucked together with air from the suction port body 15.

  The sucked dust and air are sucked into the suction connection port 57a of the dust collecting unit 50 through the extension pipe 14 and the dust collecting hose 12. Dust and air sucked into the suction connection port 57a are introduced into the separation chamber portion 54 of the dust separation portion 52 through the guide air duct 57, and rotate counterclockwise in FIG. I will do it.

  Then, the dust and air are separated by inertia by this rotation, and the air passes through the net filter NF1 (see FIG. 12) of the dust separating means 55 and the net filter NF2 (not shown) of the opening 154B, and further the suction air passage portion 56. Then, the air is sucked into the storage case 81 of the filter unit 80.

  On the other hand, the separated dust is introduced together with a part of air into the communication case portion 72 of the dust collecting container 410 from the introduction opening 53A of the separation chamber portion 54 by inertial force. The introduced dust and air are sucked into the dust collection chamber portion 73 through the communication passage 71 of the communication case portion 72, and the dust is collected in the dust collection chamber portion 73.

  The air sucked into the dust collection chamber 73 is sucked into the suction air passage 56 through the net filter NF3 together with fine dust, and further sucked into the storage case 81 of the filter 80. At this time, the fine dust is captured by the pleated filter 104.

  The air sucked into the storage case 81 passes through the pleated filter 104 of the pleated filter body 100 and is sucked into the connection air passage portion (not shown) of the cleaner body 11 and further sucked into the suction opening 24A of the electric blower 24. It will be done.

  The air sucked into the suction opening 24A of the electric blower 24 passes through the electric blower 24 and is exhausted from the exhaust port (not shown) of the cleaner body 11 shown in FIG.

  When the off switch 13a of the operation portion 13A of the hand operation tube 13 is operated, the lattice member 600 is rotated by a motor (not shown) for a predetermined time, whereby the pleat filter body 100 is rotated and the pleat filter is removed by dust removal means (not shown). The fine dust adhering to 104 is dropped.

  When the dust collected in the dust collecting container 410 is discarded after the cleaning is completed, the operation unit 701 of the clamp 700 is pressed from above. By this pressing, the clamp 700 rotates counterclockwise around the shaft portion 703 from the position shown in FIG. 7 against the biasing force of a spring (not shown).

  When the clamp 700 is rotated counterclockwise in FIG. 9, the locking claw 707 of the clamp 700 is disengaged from the distal end portion 511 of the engaging member 510 of the lid case 500, and the lid case 500 is unlocked. When this lock is released, the lid case 500 is opened by the torsion coil spring 18 (see FIG. 5) as shown by a chain line in FIG.

  On the other hand, when the clamp 700 is rotated as shown in FIG. 9, the pressing portion 705 of the clamp 700 moves the slide member 1201 to the right, and by this movement, in the lock unit 1200, the hook 72 </ b> F of the dust collecting container 410 is moved. However, it comes off from the edge 1204a of the opening 1204 of the slide member 1201, and the dust collecting container 410 is released from being fixed.

  Thereby, the ribs 72R and 74R of the dust collecting container 410 are pushed upward by the urging force of the springs 1102 and 1112 of the guide cases 1101 and 1111 as shown in FIG. That is, the dust collecting container 410 is popped up by the urging force of the springs 1102 and 1112 as shown in FIGS.

  By the way, when there is a gap between the pressing portion 705 of the clamp 700 and the distal end portion 1201a of the slide member 1201, when the operation portion 701 of the clamp 700 is pressed, first, the locking claw 707 as the locking portion and the distal end portion. 511 is disengaged and the lid case 500 is opened, and the locking means 1200 is disengaged after this. Therefore, the dust collection container 410 is reliably popped up.

  Thus, simply pressing the operation portion 701 of the clamp 700 opens the lid case 500 and pops up the dust collecting container 410, so that the dust collecting container 410 can be easily detached from the cleaner body 11.

  Next, when the dust collected in the dust collecting container 410 is discarded and then attached to the cleaner body 11, the user attaches the ribs 72R and 74R of the dust collecting container 410 to the pop-up means 1100 and 1110, respectively. Are inserted into the slits 1103 and 1113. Here, the dust collecting container 410 may be further pushed downward to be placed in the normal storage position to lock the locking means 1200, but may remain in the pop-up position shown in FIG.

  Even when the dust collecting container 410 is arranged in the pop-up position in this way, the lid case 500 is engaged with the engaging claw 707 as the lock portion and the tip portion 511 to completely close the upper opening 22A. When the dust collecting container 410 is rotated to the fully closed position, the dust collecting container 410 is pushed down to the normal storage position, and the lock unit 1200 is locked and fixed.

  That is, when the dust collecting container 410 is placed in the pop-up position and the lid case 500 is closed, the pressing portion 521 formed on the rib 522 on the back surface of the lid case 500 as shown in FIG. Comes into contact with the upper surface of the handle portion 75 of the dust collecting container 410. When the lid case 500 is further rotated in the closing direction, the dust collecting container 410 is pushed downward and pushed down against the urging force of the springs 1102 and 1112, and when it reaches the normal storage position, The hook 72F on the lower surface of the dust container 410 and the edge portion 1204a of the cylindrical portion 1203 are engaged, and the locking means 1200 is locked.

  In the first embodiment, as shown in FIG. 15, the pressing portion 521 of the lid case 500 is in contact with the handle portion 75 so that it is farthest from the center of rotation in the entire rotation locus of the lid case 500. The rotation locus from this position in the closing direction is directed substantially downward, and the dust collecting container 410 is efficiently pushed downward.

  As described above, in the first embodiment, when the dust collected in the dust collecting container 410 is discarded, when the operation of unlocking the cover case 500, that is, when the clamp 700 is pushed and rotated, the cover case 500 is moved upward. At the same time, the dust collection container 410 is released from the fixed position and lifted upward from the normal storage position.

  Thus, since the dust container 410 is unlocked and popped up, it is easier to take out and the dust container 410 is unlocked in addition to the operation of the clamp 700 compared to the case where the dust container is not popped up. The number of operations is small and easy to take out as compared with the conventional one.

  Further, when the dust collection container 410 is stored in the regular storage position, after the dust collection container 410 is placed in the pop-up position, the lid case 500 is locked by the locking claw 707 as the lock portion, and the upper opening 22A is completely opened. When rotating to the closed fully closed position, the dust collecting container 410 is simultaneously pushed down to the normal storage position and fixed by the locking means 1200 as the fixing means.

  For this reason, the number of operations is small and the operation is easy compared to performing the mounting of the dust collecting container 410 to the regular storage position and the fully closing operation of the lid case 500, respectively.

  In addition, after the user places the dust collection container 410 in the pop-up position, the user forgets to push the dust collection container 410 to the regular storage position or the pushing operation force is insufficient, so that the dust collection container 410 is fixed at the regular storage position. Even when the lid case 500 is closed, it is moved and fixed to the regular storage position even when the lid case 500 is closed. In this way, the dust collection container is reliably arranged at the regular storage position.

  For this reason, when the vacuum cleaner 10 is used after the lid case 500 is closed, the dust collecting container 410 is not properly attached, and malfunction does not occur, resulting in excellent operability.

  Furthermore, in the first embodiment, since the pressing portion 521 is formed in a part of the reinforcing rib 522 of the lid case 500, compared to forming the pressing portion 521 separately from the rib 522, If the height is the same, the amount of material used can be reduced, which is advantageous in terms of cost.
