  The dust removing member 13 and the upper lid 8 are provided with a rotation preventing means 53 for preventing the dust removing member 13 from rotating. The rotation preventing means 53 includes the rotation preventing rib 56 formed on the upper lid 8 and the rotation. It is composed of both side surfaces of the prevention rib 56 and a wall portion 52 formed with a slight gap, and is provided at a plurality of locations at equal intervals. That is, the wall 52 is formed in the dust removing member 13 so as to sandwich the rotation preventing rib 56.

  Further, the upper lid 8 is formed with a claw portion 50 for temporarily fixing the dust removing member 13 to the upper lid 8 in the middle of assembly at the lower end of the rotation preventing rib 56, and the dust removing member 13 has the claw portion 50.

  Further, the dust collecting container 7, the bottom lid 9, and the collecting member 23 are formed of a material having at least a part thereof.

About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
Air containing dust sucked from the suction tool 5 is sucked into the dust collecting device 6 from the intake port 15 via the extension pipe 4 and the hose 2. Since the intake port 15 is formed so as to face the tangential direction of the dust collecting container 7, the sucked air swirls along the inner peripheral surface of the dust collecting container 7, and is separated into dust and air. Is done.

  The separated dust accumulates below the dust collection container 7 or in a space between the collection member 23 and the bottom cover 9, and the air from which the dust is separated passes through the inner cylinder opening 25. And flows into the upper filter 12. The air that has flowed into the upper filter 12 contains a very small amount of dust that could not be separated a little, and the dust is collected on the upstream surface of the upper filter 12. The air that does not contain dust that has passed through the upper filter 12 passes through the suction passage 40 formed in the upper lid 8, is sucked into the electric blower, and is discharged out of the main body 1 of the vacuum cleaner.

In order to remove dust collected by the upper filter 12, the operation member 14 is rotated to rotate the connection member 34 and the projection 37 fixed by the operation member 14 and the screw 35. The rotation preventing rib formed on the upper lid 8 by the wall portion 52 formed on the dust removing member 13 while the crest portion 38 formed on the dust removing member 13 comes into contact with the inclined surface of the convex portion 37. When the rotation of the dust removing member 13 is restricted by coming into contact with 56, the mountain portion 38 operates so as to ride on the inclined surface.

  Due to the movement of the peak portion 38, the dust removing member 13 slides in a direction away from the upper filter 12 against the urging force of the elastic body 36 (a direction substantially perpendicular to the downstream surface of the upper filter 12). When the peak portion 38 gets over the convex portion 37, the dust removing member 13 slides toward the downstream surface of the upper filter 12 by the biasing force of the elastic body 36, and is formed in the dust removing member 13. The dust removing portion 58 is in contact with the upper filter 12, and dust applied to the upper filter 12 can be removed by giving an impact.

  In the present embodiment, since the convex portion 37 is formed at 12 locations, when the operation member 14 is rotated once, the upper filter 12 is moved 12 times by the dust removing portion 58 formed on the dust removing member 13. You will be shocked.

  The dust removed here passes through the inside of the inner cylinder 26 and falls into the bottom cylinder portion 29 to be accumulated. The dust accumulated in the dust collector 6 slides the lever body 18 downward, so that the locking portion 19 provided on the bottom lid 9 operates and the locking with the dust collecting container 7 is released. When the bottom cover 9 is opened, the dust accumulated under the dust collecting container 7 and inside the bottom cylindrical portion 29 is discharged to the outside of the dust collecting device 6.

  When the fine filter adhering to the upper filter 12, the inner cylinder filter 28, the dust collecting container 7, the collecting member 23 or the like is to be cleaned, the care brush 16 is removed from the brush holding portion 17, Care can be taken at the brush or handle. First, the dust collecting device 6 is detached from the electric vacuum cleaner main body 1, removed from the dust collecting container 7 by opening the buckle 11 pivotally supported on the upper lid 8, and holding the handle 10. The upper lid 8 is removed from the dust collecting container 7. At this time, each component constituting the dust removing means such as the dust removing member 13 is also removed integrally with the upper lid 8.

  Next, the upper filter 12 can be taken out by grasping and lifting the filter knob 41. Further, the filter storage portion 27 can be taken out together with the inner cylinder 26 and the collecting member 23 when the storage knob portion 42 is grasped and lifted.

  After cleaning each part, the storage regulating rib 45 of the filter storage section 27 is inserted from above along the engagement rib 46 of the dust collecting container 7, and the positioning rib 43 of the upper filter 12 is inserted into the positioning rib 43. The upper filter 12 is inserted in accordance with the concave portion 44 of the filter storage portion 27. Finally, the upper cover 8 with dust removing means is attached to the dust collecting container 7 and locked by the buckle 11, and the dust collecting device 6 is housed in the main body 1 of the vacuum cleaner.

  As described above, in the present embodiment, the dust removal member 13 reciprocates in the direction of the upper filter 12 in conjunction with the turning operation of the operation member 14, so that the operation member 14 can be operated. Since the upper filter 12 can be repeatedly subjected to an impact, a high dust removal effect can be obtained even with a rotating operation with a small number of operation members 14, and the usability can be improved.

  Further, by forming a plurality of convex portions 37 in the circumferential direction on the connecting member 34 that reciprocates the dust removing member 13, the number of the convex portions 37 is the same as the number of rotation operations of the operating member 14. Since the impact of the number of times can be given to the upper filter 12, a high dust removal effect can be obtained even with a rotating operation with a small number of operation members 14, and the usability can be improved.

Further, since the dust removing member 13 is formed so as to be substantially circular and to cover more than half of the upper surface of the upper filter 12, an impact can be simultaneously applied to a wide range of the folded portion 33 of the upper filter 12. A high dust removal effect can be obtained even with a rotating operation with a small number of members 14, and usability can be improved.

  Further, by forming the peak portions 38 in the dust removing member 13 in a smaller number than the convex portions 37, it is possible to reduce the wear due to the contact between the convex portions 37 and the peak portions 38 as much as possible. Durability can be sustained. In particular, it is possible to suppress wear on the inclined surface of the convex portion 37 that affects the operating force of the operating member 14.

  Further, since the ridges 38 are formed at equal intervals, the portions where the projections 37 and the ridges 38 abut each other at the same timing, so that the dust removing member 13 is evenly balanced. Since it can slide and give an impact to a wide range at the same time, the upper filter 12 can be efficiently dedusted.

  Further, since the operation member 14 can be operated from the outside of the dust collector 6, even if the dust accumulated in the dust collector 6 is not discharged to the outside, the operation member 14 is operated to remove the dust adhering to the upper filter 12. If removed, clogging of the upper filter 12 is eliminated, and a reduction in suction force can be prevented. Further, since the user can operate the operation member 14 whenever he / she wants to operate, the usability can be improved.

  Further, the rotation prevention means 53 for preventing the rotation of the dust removing member 13 is sandwiched by the rotation prevention rib 56 between the wall portions 52 formed with a slight gap between both side surfaces of the rotation prevention rib 56. The wall portion 52 is in contact with the side surface of the rotation prevention rib 56 when a force in the rotation direction is applied to the dust removing member 13. Thus, the dust removing member 13 is regulated so as not to rotate with respect to the upper lid 8, and the dust removing member 13 is moved to the convex portion 37 when the mountain portion contacts the inclined surface of the convex portion 37 of the connecting member 34. Further, since it can move smoothly in the normal sliding direction without rotating together, the usability of the operation member 14 can be improved.

  The main parts constituting the dust removing means of the upper filter 12 are the operation member 14, the connecting member 34, the elastic body 36, and the dust removing member 13, and the number of parts can be reduced as compared with the parts structure of the conventional dust removing means. At the same time, the weight can be reduced.

  Further, the umbrella portion 21, the rib body 22, and the shielding member 24 formed on the collecting member 23 are provided at the lower portion of the inner cylinder 26, and when viewed from the bottom cover 9, a protective wall is disposed above. Therefore, it is possible to prevent dust accumulated near the bottom lid 9 from rising to the inner cylinder opening 25.

  Further, the upper lid 8 is formed with a filter pressing rib 47 that prevents the upper filter 12 from moving upward and a storage portion pressing rib 48 that prevents the filter storage portion 27 from moving upward. Airtightness can be reliably maintained in the filter packing 32, the storage unit packing 31, and the center bottom packing 30.

Further, a claw portion 50 for temporarily fixing the dust removing member 13 to the upper lid 8 is formed at the lower end of the rotation prevention rib 56 on the upper lid 8, and the dust removing member 13 is hooked to engage with the claw portion 50. By forming the part 51, in the assembly of the dust removing member 13, the dust removing member 13 is assembled so as to be sandwiched between the operation member 14 and the connecting member 34. At that time, the dust removing member 13 is formed on the dust removing member 13. When the hook portion 51 is engaged with the claw portion 50 formed on the rotation prevention rib 56 of the upper lid 8, the dust removing member 13 is not affected by the repulsive force of the elastic body 36. 14 and the connecting member 34 can be brought into a stable temporary assembly state before the screw tightening, so that the connecting member and the operating member can be easily screwed and the assemblability can be improved.

  Further, when the upper lid 8 is removed from the dust collection container 7, the upper filter 12 and the filter storage portion 27 can be attached and detached simply by lifting or inserting from the dust collection container 7 in the vertical direction. The dust device 6 can be easily disassembled and assembled, and usability can be improved.

  Further, since the position of the filter knob 41 and the position of the storage knob 42 are provided so as not to overlap with each other, they can be easily taken out without interfering with each other when gripping each knob.

  Further, the misassembly prevention rib 49 is formed on the upper lid 8, and when the storage knob portion 42 is viewed from the side, the upper lid 8 is asymmetrical with respect to the central axis of the dust collector 6. When the assembly is attempted to be assembled at an irregular position, the storage knob portion 42 of the filter storage portion 27 interferes with the erroneous assembly prevention rib 49, and the locking of the buckle 11 becomes impossible. Incorrect assembly can be prevented.

  Further, since the upper filter 12 is not provided with parts constituting dust removing means, it can be easily maintained.

  In addition, since at least a part of the dust collecting container 7, the bottom lid 9, and the collecting member 23 is formed of a visible material, the amount of dust accumulated in the dust collecting device 6 can be confirmed. The user can easily determine when to throw away the garbage.

  A plurality of substantially rib-like sliding ribs 54 are formed between the dust removing member 13 and the connecting member 34 on the dust removing member 13 so as to reduce the sliding resistance of the dust removing member 13. Therefore, since the contact area is small, the sliding resistance of the dust removing member 13 is reduced, so that it can operate smoothly, and an impact can be applied to the upper filter 12 efficiently.

  Further, by providing the avoidance space 55 between the sliding ribs 54, the dust removing member 13 and the connecting member when the upper lid 8 is removed from the dust collecting container 7 for cleaning, etc. Even if a minute dust enters between 34, there is a space in which the minute dust can be moved. Can be prevented.

  In the present embodiment, the convex portion 37 has 12 locations and the mountain portion 38 has 3 locations. However, the convex portion 37 is formed with a number other than a prime number, and the peak portion 38 is formed on the convex portion 37. If the projections 37 and the ridges 38 are in contact with each other at the same timing, the dust removal member 13 can be operated with a good balance, so that it is more efficient. Dust removal effect can be obtained.

  Further, in the present embodiment, the number of the convex portions 37 is twelve. However, if the number is further increased, the reciprocating operation of the dust removing member 13 is increased. A dust removal effect is obtained. Further, if the number is reduced, the contact between the convex part 37 and the peak part 38 is reduced, so that wear of the peak part can be suppressed and durability can be improved.

  Further, in the present embodiment, there are three ridges 38, but when there are more ridges, the number of places where the projections 37 and the ridges 38 abut increases, and the dust removing member 13 is more balanced. Since it can operate | move, the dust removal effect is acquired more efficiently.

  In the present embodiment, a convex portion having an inclined surface is formed on the connecting member and a mountain portion is formed on the dust removing member. On the contrary, a convex portion having an inclined surface is formed on the dust removing member, and the connecting member is formed. The same effect can be obtained even if the ridges are formed.

  In the present embodiment, the dust removing portion is formed in a circular shape, but the same effect can be obtained even if it is formed in a polygonal shape such as a quadrangle or an elliptical shape.

FIG. 12 is a perspective view of the upper lid including the dust removing means of the dust collector in the second embodiment of the present invention, FIG. 13 is a cross-sectional view of the main part of the upper lid including the dust removing means of the dust collector, and FIG. FIG. 15 is an overall perspective view of the dust removing member of the dust collector, and FIG. 15 is a cross-sectional view taken along line BB in FIG. 3 of the dust collector.

  In the dust collector in the present embodiment, the dust removing portion 58 that forms the dust removing member 13 is formed by the outer dust removing portion 59 and the inner dust removing portion 60, and the arm portion 61 that connects the outer dust removing portion 59 and the inner dust removing portion 60. Are formed at equal intervals, and a hole portion 62 through which exhaust gas passes is formed between the arm portions 61.

About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
The air that does not contain dust that has passed through the upper filter 12 passes around the dust removing member 13 and the hole 62, passes through the suction passage 40 formed in the upper lid 8, and is sucked into the electric blower, and the main body of the vacuum cleaner 1 is exhausted outside.

  In order to remove the dust collected by the upper filter 12, by rotating the operating member 14, the connecting member 34 and the projection 37 fixed by the operating member 14 and the screw 35 are also rotated, A crest portion 38 formed on the dust removing member 13 abuts on the inclined surface of the convex portion 37, and a wall portion 52 formed on the dust removing member 13 abuts on a rotation prevention rib 56 formed on the upper lid 8 and the dust removing When the rotation of the member 13 is restricted, the mountain portion 38 operates so as to ride on the inclined surface.

  By the operation of the peak portion 38, the dust removing member 13 slides in a direction away from the upper filter 12 against the urging force of the elastic body 36 (a direction substantially perpendicular to the downstream surface of the upper filter 12). Then, when the peak portion 38 gets over the convex portion 37, the dust removing member 13 slides toward the downstream surface of the upper filter 12 by the urging of the elastic body 36, and the dust removing member 13 is formed. The outer dust removing portion 59 and the inner dust removing portion 60 of the dust removing portion 58 are in contact with the upper filter 12, and dust attached to the upper filter 12 can be removed by giving an impact.

  As described above, in the present embodiment, the dust removal member 13 reciprocates in the direction of the upper filter 12 in conjunction with the turning operation of the operation member 14, so that the operation member 14 can be operated. Since the outer dust removing portion 59 and the inner dust removing portion 60 are in contact with the upper filter 12 and can repeatedly give an impact to the upper filter 12, a high dust removal effect can be obtained even with a small rotation operation of the operation member 14, and it is easy to use. Can be improved.

  In addition, since a plurality of the holes 62 are formed between the outer dust removing part 59, the inner dust removing part 60 and the arm part 61 in the dust removing member 13, a part of the air that has passed through the upper filter 12 is formed. Since the gas is smoothly exhausted by passing through the hole 62, the air permeability can be improved and the suction force can be improved while maintaining high dust removal performance.

Further, since the arm portions 61 are regularly arranged, the air permeability can be improved and the strength of the dust removing portion 58 can be secured.

  In the present embodiment, the outer dust removing portion is formed in a circular shape, but the same effect can be obtained even if it is formed in a polygonal shape such as a quadrangle or an elliptical shape.

  As described above, the vacuum cleaner according to the present invention includes a dust collecting device that can obtain a high dust removal effect even with a rotating operation with a small number of operation members, and can improve usability. It can be applied to other uses.
