  Next, the cleaning operation according to the embodiment will be described with reference to FIGS.

  When cleaning is started, the assembled dust collector 27 is attached to the main body case 26. When the dust collector 27 is assembled, the separation main body 52 and the magnet 57 are attached to the cup 51. The separation main body 52 is attached to the cup 51 so that the insertion portion 71 and the wall portion 73 are inserted into the dust disposal port 65 from above the cup portion 51. In addition, the magnet 57 picks the knob 69a of the magnet holder 69 and inserts it in an inclined shape or the like above the holding claw 68 of the magnet mounting part 56 of the cup part 51, and then within the magnet mounting part 56 The magnet holder 69 is slid downward, and the magnet holder 69 is attached to the cup portion 51 by being held and held on the cup portion 51 (magnet mounting portion 58) by the holding claws 68.

  Then, when the assembled dust collector 27 is placed on the protruding receiving portion 32 from the upper front side with respect to the mounting portion 33 of the main body case 26, the magnet 57 is attracted to the magnetic body 38, and the holding claw 68 is inserted into the concave portion 70, respectively. Thus, the dust collector 27 is held in a state of being positioned with respect to the main body case 26. At this time, for example, when the user operates the setting button 22 of the hand operating unit 17 or operates an operating unit such as a separate button, the magnetic force of the magnetic body 38 is relatively increased, so that The dust device 27 is securely held with respect to the main body case 26. As a result, the inlet 42 and the outlet 47 are airtightly connected to the communication opening 37 and the intake opening 36 of the main body case 26, respectively, and the dust collector 27 is located between the suction side of the electric blower 35 and the main body suction port 40. It is attached to the main body case 26 in an airtight connection state. That is, the dust collector 27 is positioned in a state where the axial direction is along the vertical direction. Note that when the dust collector 27 is already attached to the main body case 26, these operations are not necessary.

  In this state, the pipe part 12 is connected to the main body suction port 40 of the cleaner main body 13 (main body case 26). Specifically, the pipe part 12 inserts and connects the connection pipe part 15 to the main body suction port 40, and sequentially connects the extension pipe 18 and the floor brush 19 to the distal end side of the hand operation part 17 as necessary. In this state, the setting button 22 of the hand operation unit 17 is electrically connected to a control circuit unit in the cleaner body 13 (main body case 26) and the like. In addition, when the pipe part 12 is already connected to the cleaner body 13, these operations are unnecessary.

  Then, after the user pulls out the power cord from the cord outlet and connects it to an outlet such as a wall surface, the user grips the gripping part 21 and operates the desired setting button 22 to set the operation mode of the electric blower 35. To do. The control circuit unit controls the input of the electric blower 35 corresponding to the set operation mode, and starts the electric blower 35 in the set operation mode.

  The negative pressure generated by the activation of the electric blower 35 includes the intake opening 36, the discharge port 47, the air passage 46, the second separation part 45, the air guide part 44, the first separation part 43, and the first dust collection part 61. Then, it acts on the pipe portion 12 via the introduction port 42, the communication opening 37, the main body air passage portion, and the main body suction port 40.

  The user sucks dust together with air from the front end side of the floor brush 19, the extension pipe 18, or the hand operation unit 17 by the action of the negative pressure.

  The dust-containing air, that is, the dust-containing air, is guided from the pipe portion 12 to the inlet port 42 via the main body suction port 40, the main body air passage portion, and the communication opening portion 37, and the dust collector from the inlet port 42 The 27 cup parts 51 are sucked into the cup body part 54.

  In the cup body 54, the dust-containing air swirls in the air passage 79, so that particularly coarse dust in the dust-containing air is centrifuged and falls along the inner surface 51 a of the cup portion 51, thereby collecting the first dust. Stored in part 61. The coarse dust is carried from the air passage 79 to the shade portion 76 by a part of the flow of the dust-containing air, and is compressed in the shade portion 76. Further, the metal dust contained in the dust collected in the first dust collecting portion 61 is attracted to the position facing the magnet 57 on the inner surface 51a of the cup portion 51 (cup body portion 54) by the attracting force of the magnet 57. And separated from other dust.

  The dust-containing air from which coarse dust is mainly separated is filtered by the separation filter 78 when passing through the opening 77 of the inner cylinder portion 75. Further, the dust-containing air that has passed through the separation filter 78 is carried to the air guide section 44. The dust-containing air is rectified by gradually reducing the flow rate in the air guide section 44, and then flows into the second separation sections 45 by branching.

  In these second separation parts 45, the dust-containing air is swirled along the inner peripheral surface, the fine dust in the dust-containing air is centrifuged, falls along the cone part 85, and the wall part 73 is inclined. It is led to the second dust collecting part 66 and stored.

  The fine dust-centrifuged air that is substantially free of dust is exhausted from the central portion of each second separation portion 45 to the air passage portion 46 and joined, and the air passage portion 46 restricts the flow rate. Then, it is guided rearward and exhausted from the outlet 47 to the outside of the dust collector 27.

  Thereafter, the air passes through the intake opening 36 and is then sucked into the electric blower 35, passes through the electric blower 35 while cooling, and becomes exhausted air, and is discharged from the electric blower 35 through the exhaust hole. The air is exhausted to the outside of the main body case 26.

  When the cleaning is completed, the user operates the predetermined setting button 22 so that the control circuit unit decreases the input of the electric blower 35 and stops the electric blower 35.

  At this time, if the dust collecting device 27 can be removed from the main body case 26 every time cleaning is completed, the magnetic material is collected when the electric blower 35 is stopped or when a predetermined short period of time has elapsed since the stop. By making the magnetic force of 38 relatively small, the adsorption of the magnetic body 38 and the magnet 57 is released or weakened, and the dust collector 27 can be removed from the main body case 26. On the other hand, when the dust collector 27 is to be removed from the main body case 26 when a certain amount of dust has accumulated in the dust collector 27, for example, the user can, for example, set the setting button 22 of the hand operation unit 17 or separately. When the operation unit such as a button is operated, or when it is detected by the sensor that detects the amount of dust that a predetermined amount or more of dust has accumulated in the cup unit 51, the magnetic force of the magnetic body 38 is automatically relative. By reducing the size, the adsorption of the magnetic body 38 and the magnet 57 is released or weakened, and the dust collecting device 27 can be detached from the main body case 26.

  Then, the dust collector 27 removed from the main body case 26 removes the separation main body portion 52 from the cup portion 51. As a result, the adhesion of the seal member 88 to the partition 55 is released, and the fine dust collected in the second dust collector 66 falls and moves to the first dust collector 61 inside the cup body 54, The dust falls on the upper side of the coarse dust accumulated in the first dust collecting portion 61 and is mixed with the coarse dust.

  After this, the user grips the dust collector handle 63 and carries the cup 51 to a disposal position such as a trash can, and then turns the upper side to tilt downward so that the cup 51 is compressed. Coarse dust accumulated in this state and fine dust mixed with the coarse dust are simultaneously discarded from the dust disposal port 65.

  Further, the metal dust adsorbed to the inner surface 51a of the cup part 51 by the magnet 57 is discarded by removing the magnet 57 from the cup part 51 at a predetermined disposal position. At this time, the user picks the knob 69a, slides the magnet holder 69 upward in the magnet mounting portion 56 to disengage the holding claws 68, and removes the magnet holder 69 from the magnet mounting portion 56. Thus, the magnet 57 can be removed from the cup portion 51.

  According to the embodiment described above, the magnet 57 for applying a magnetic force in the first dust collecting portion 61 is provided with the dust collecting device 27 open to a predetermined direction side of the main body case 26, in this embodiment, the front portion. By attaching magnetically to the magnetic body 38 in a state of being attached to the attachment portion 33, the metal dust in the cup portion 51 of the dust collector 27 can be separated by the magnetic force of the magnet 57, and for example, an L-shaped engagement There is no need for a structure for hooking the claws on the main body case 26 side, the dust collecting device 27 can be easily attached to the main body case 26, and the structure of the dust collecting device 27 can be simplified.

  By making the magnet 57 detachable from the cup portion 51, the magnet 57 is disposed when the metal 57 separated from the dust collected in the first dust collecting portion 61 is disposed by attaching the magnet 57 to the cup portion 51. Is removed from the cup part 51, so that the suction force of the metal dust to the cup part 51 can be eliminated and the air can be easily exhausted.

  Since the magnetic force of the magnetic body 38 can be changed, the dust collector 27 is held in the main body case 26 while the magnetic force of the magnetic body 38 is relatively large, so that the dust collector 27 is not detached from the main body case 26. The dust collector 27 can be removed from the main body case 26 with the magnetic force of the magnetic body 38 relatively lowered.

  Further, since dust is collected in the first dust collecting part 61 below the cup part 51 by gravity, the introduction port 42 is arranged at the upper part of the dust collecting device 27, and the magnet 57 is arranged therebelow, Extra space is not required, and the dust collector 27 can be configured compactly.

  In the above embodiment, the second separation unit 45 may be a filter for filtering fine dust from dust-containing air, or if the first separation unit 43 and the separation filter 78 can reliably separate coarse dust and fine dust. It is not necessary to provide it.

  In addition, although the attachment portion 33 of the main body case 26 is opened to the front portion, it may be configured to open to other predetermined direction sides such as the upper portion or the upper front portion.

  Although one embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
