  Next, the operation of the above embodiment will be described.

  When cleaning is started, first, the dust collection cup 52 is assembled and then attached to the main body case 51 in advance, and the filter 63 is attached to the main body case 51 in advance.

  In the dust collection cup 52, the seal member 143 is brought into pressure contact with the step portion 120 by inserting the cover portion 114 from above into the cup portion main body 111, and the first reservoir 65 and the second reservoir 66 are partitioned. And the separated body portion 115 integral with the cover portion 114 is coaxially inserted into the cup portion main body 111 to constitute the first centrifugal separation portion 61, and the exhaust cylindrical portion 122 is disposed on the separated body portion 115 from below. It is inserted and airtightly connected with the lower end of the exhaust part 162. Further, a part of the brush body 152 is fitted in the opening portion 151 and fixed to the cover portion 114 (FIG. 4).

  Then, by aligning the assembled dust collection cup 52 with the mounting opening 77 of the main body case 51 and pushing it toward the main body case 51 (case main body 73) side, the upper end of the cup part main body 111 of the dust collection cup 52 Is pressed against the seal member 84, and the seal member 102 located under the partition 93 of the unit 81 of the main body case 51 is press-contacted with the cover press-contact 142 of the cover 114 located above the dust collection cup 52 Thus, the communication air passage 69 is formed, and the lower end of each separation cylinder 94 is inserted into each communication opening 141 so that each dust discharge port 106 is in communication with the second reservoir 66. On the other hand, the upper end of the exhaust part 162 is pressure-welded and the exhaust part 162 is airtightly connected with the discharge opening 100, and the pressure-welding part 124 of the introduction part 113 is pressure-welded to the seal part 88 and the introduction air passage 68 is In a state of being airtightly connected to the rear end portion on the downstream side of the body connection portion 79 (air passage body 15), The dust collecting cup 52 is locked and held by the main body case 51 by the action of the lamp 117.

  In addition, the filter 63 inserts the discharge cylindrical portion 104 into each filter opening 63c and positions it with respect to the case main body 73, aligns the lid 74 with respect to the exposed opening 75, and pushes the case 74 side. Thus, the lid 74 is locked and held by the case main body 73 by the action of the locking clamp 107 while the gap between the case main body 73 and the lid 74 is closed.

  When the dust collection cup 52 and the filter 63 are already attached, the above-described respective operations are unnecessary.

  As a result, from the air passage body 15, the introduction air passage 68 (the check valve 126 and the suction port 125), the first centrifugal separation unit 61, the opening 164 (separation filter 165), the communicating air passage 69, the suction opening 103 , The second centrifugal separator 62, the discharge opening 105, the suction air passage 70 (the upper air passage 178, the filter 63 and the lower air passage 179), the suction opening 96 and the suction connected with the electric blower 53 (suction inlet 53a) An air passage and an exhaust air passage communicating with the electric blower 53 (exhaust port), the exhaust opening 100, the exhaust portion 162, the exhaust cylinder portion 122, and the exhaust opening 171 are airtightly formed.

  And when using the vacuum cleaner 11 as a stick type | mold, as shown, for example to FIG. 8 and FIG. 10, the rear end part of the handle 38 of the air passage body 15 is the position of the holding | maintenance receiving part 78 with respect to the main-body part 16. After the attachment portion 18 is attached and detached as required, the main body handle 80 is gripped to clean the entire body while moving.

  When the vacuum cleaner 11 is used as a handy type, for example, as shown in FIG. 9, the floor brush 21 or the attachment portion 18 is removed from the hose portion 19 and the handle 38 is gripped to make the air passage body 15 a main body The main body 16 is carried away by the main body handle 80, and the main body 16 is carried by shouldering with the belt (shoulder belt) (not shown). The position of the air passage body 15 is manipulated for cleaning while expanding (stretching) the fifteen hose bodies 35.

  Then, when the user operates the setting button 89 at the start of cleaning, the main control unit controls the electric blower 53 by conducting angles, and the electric blower 53 is driven in a desired operation mode to generate a negative pressure. Dust is sucked from the air passage body 15 together with air.

  Air sucked into the air passage body 15 together with dust, that is, dust-containing air flows from the downstream end of the hose body 35 of the air passage body 15 into the introduction air passage portion 68 via the air passage body connecting portion 79 and reversely It is guided along the outer side of the introduction part 113 while being rectified by the valve body 128 of the stop valve 126 and sucked into the first centrifugal separation part 61 along the tangential direction of the inner peripheral surface of the cup part main body 111 from the suction port 125 Be After this, the dust-containing air is swirled between the inner peripheral surface of the dust collection cup 52 (cup portion main body 111) and the outer peripheral surface of the separated portion main portion 161 of the separated portion 115 and particularly large dust (coarse dust) Is centrifugally separated from the air by its own weight, falls along the inner peripheral surface of the cup body 111, and is collected in the first reservoir 65 of the cup body 111. The dust is pressed and compressed against the compression filter 167 by passing a part of the swirling flow in the cup portion main body 111 from the lower end of the compression portion 163 through the compression opening 166 (compression filter 167). It accumulates inside.

  Air from which dust has been centrifugally separated flows into the opening 164 while passing through the separation filter 165. The air having passed through the opening 164 (separation filter 165) passes through the communicating air passage 69 while being rectified by the smooth cylindrical outer periphery of the exhaust unit 162, and cools the electric blower 53 together with the electric blower chamber 91. Furthermore, the air that has passed through the communication air passage 69 flows into the second centrifugal separator 62 through the suction opening 103, and the second centrifugal separator 62 follows the inner circumferential surface of the separation cylinder 94. It is swirled and fine dust is further centrifuged. The separated fine dust drops from the dust discharge port 106 at the lower end of the separation cylinder 94 to the second reservoir 66 in the dust collection cup 52 and is collected. The air from which the fine dust has been separated flows out from each discharge opening 105 to the upper air passage 178 of the suction air passage 70, and the entire filter 63 is inclined in the thickness direction (vertical direction) toward the suction opening 96. The dust (fine dust) slightly remaining after passing through the lower air passage 179 is filtered and collected by the filter 63, and is sucked into the suction port 53a of the electric blower 53 from the suction opening 96.

  The air sucked into the electric blower 53 passes while cooling the electric blower 53 and becomes exhaust air, and is discharged from the exhaust port into the electric blower chamber 91, and then the lower portion of the electric blower chamber 91. Is rectified by the smooth inner circumferential surface of the exhaust portion 162 and the exhaust cylindrical portion 122 from the discharge opening 100 of the lower portion of the separation body portion 115 and passes downward to the outer side of the dust collection cup 52 (main body portion 16) , And are dispersed by the ribs 123 and guided to the respective exhaust openings 171, and dispersed and exhausted from the exhaust openings 171 along the radial direction.

  When the cleaning is completed, the user operates the setting button 89 to stop the electric blower 53, installs the cleaner 11 in the charging device 12, stores it, and charges the secondary battery 174.

  At this time, the vacuum cleaner 11 first operates the holding clamp 40 of the suction port body portion 34 to remove the attachment portion 18 from the hose portion 19. The removed attachment portion 18 inserts the hook portion 33 into the locking and holding portion 196 from the upper side and holds it.

  The vacuum cleaner 11 from which the attachment portion 18 has been removed is inserted from above into the insertion opening 191 while the air passage body 15 is connected to the main body portion 16 at the position of the rear end of the handle 38 by the holding receiving portion 78. .

  At this time, the vacuum cleaner 11 inserts the air passage body 15 on the lower side and the main body portion 16 on the upper side, that is, from the air passage body 15 into the insertion opening 191. This insertion can be performed by natural operation by holding the main body handle 80 located on the opposite side of the air passage body 15 in the main body portion 16.

  The main body portion 16 is positioned by the positioning portion and supported from below, and the substantially entire main body portion 16 is placed on the holding portion 188 and the introducing portion is introduced. In addition, the charging terminal 176 is inserted into the terminal portion 198 from above and electrically connected. In this state, the main body portion 16 has the dust collection cup 52, the electric blower 53, the filter 63 (the lid 74), the secondary battery 174, etc. positioned above the upper end of the holding portion 188, etc. The side where the lid 52 and the lid 74 are separated from the main body case 51, that is, the rear (and upper side) of the dust collecting cup 52 and the front of the lid 74 are not regulated respectively, and the clamp 117 of the dust collecting cup 52 The lock clamp 107 for exposing the top of the dust cup 52 and for locking the lid 74 to the case body 73 is exposed above the inclined portion 193a, and the clamp 117 and the lock clamp 107 can be operated. It has become (Figure 1). Therefore, the dust collecting cup 52 and the lid 74 can be removed from the main body case 51 by operating the clamp 117 and the locking clamp 107 with the introduction portion 113 as a fulcrum.

  When the charging device 12 recognizes the installation of the vacuum cleaner 11 through the terminal portion 198 or the like, the power supplied from the external power supply through the power supply adapter 181 is supplied to the charging circuit of the vacuum cleaner 11 through the terminal portion 198 to The charging circuit is driven, and the charging circuit charges the secondary battery 174. The charging circuit monitors, for example, the charge state of the secondary battery 174, and stops charging when it is confirmed that the secondary battery 174 has reached a predetermined charge state (full charge).

  Further, when discarding dust, the dust collecting cup 52 is used as a main body case 51 (by operating the clamp 117 while holding the cup main body 111 by putting a hand on the non-slip portion 121 from the state shown in FIG. Remove from the mounting opening 77). That is, in the vacuum cleaner 11 attached to the charging device 12, the dust collection cup 52 whose axial direction is the horizontal direction crossing (orthogonal to) the vertical direction which is the longitudinal direction of the main body case 51 is the axis of the dust collection cup 52. Along the horizontal direction, which is the direction, it is removed while being rotated backward while using the introduction portion 113 as a fulcrum. At this time, although the dust collection cup 52 is in a state where the suction port 125 is directed downward, the outer edge of the front surface of the valve body 128 when the negative pressure of the electric blower 53 does not act on the check valve 126 When the valve body 128 abuts on the suction port 125 opposite to the cup body 111 (on the side opposite to the cup body 111), dust comes from the first reservoir 65. The dust does not open downward, and dust in the first reservoir 65 does not spill out of the suction port 125 through the introduction portion 113. Further, the dust collecting cup 52 removed from the main body case 51 has the upper portions of the first reservoir portion 65 and the second reservoir portion 66 by the cover portion 114 because the cover portion 114 is attached to the cup portion main body 111. Covered, contained dust does not rise. Furthermore, even if dust is temporarily attached on the cover portion 114, this dust falls to the holding portion 188 side, and therefore does not fall on the placement surface (cleaned surface). In this state, the user carries the dust collection cup 52 to a disposal position such as a trash can, and picks the picker 146 to remove the cover 114 from the cup body 111. At this time, the knob portion 146 is located in the space portion 148 outside the air passage communicating with the suction side of the electric blower 53, so that the knob portion 146 is not in contact with dusty air, and dust is not attached. To keep the user's hands clean. Then, the user turns the cup body 111 upside down and discharges the dust in the first reservoir 65 and the second reservoir 66 from the dust disposal port 118. The cover 114 removed from the cup body 111 is removed by sliding the brush body 152 attached to the upper part of the cover 114 upward, and separation of the separated body 115 integral with the cover 114 is performed. The dust attached to the filter 165 and the compression filter 167 or the dust attached to the surface of the dust receiving portion 112 or the like is removed and maintained (maintenance). Then, after the dust is removed, the dust collection cup 52 can be remounted and used.

  In addition, since almost no dust remains in the air after passing through the second centrifugal separation part 62, the filter 63 is not substantially clogged, and maintenance is basically unnecessary. The cover 74 is removed forward from the case body 73 by operating the locking clamp 107 exposed above the holding portion 188 (the expanding portion 193) of the charging device 12, and the exposed opening 75 is exposed. The dust attached to the filter 63 can also be removed by removing (FIG. 3) or tapping.

  As described above, in the case of the stick-type vacuum cleaner 11, since it does not stand alone as it is, in order to remove the dust collection cup, an operation such as placing it on a floor surface or the like is required. Therefore, according to the embodiment described above, the main body portion 16 is held by the holding portion 188 in a state where the vacuum cleaner 11 (main body portion 16) is inserted into the holding portion 188 with the introduction portion 113 facing downward. And the clamp 117 is mounted on the charging device 12 so that the clamp 117 can be operationally exposed above the dust collection cup 52. Therefore, at least a part of the dust collection portion 54, in the present embodiment, the first centrifugal The dust collection cup 52 having the separation part 61 and the storage part 56 (first and second storage parts 65 and 66) inside can be removed from the main body case 51.

  Further, in a state where the vacuum cleaner 11 is attached to the charging device 12, the lid 74 is positioned above the holding portion 188 and the locking clamp 107 is also exposed so as to be operable. The body 74 is removed, and the filter 63 disposed on the suction side of the electric blower 53 can be removed from the main body case 51.

  Therefore, the dust collection cup 52 and the filter 63 can be easily removed, and dust can be easily discarded.

  Further, the electric blower 53 and the second centrifugal separation portion 62 are disposed in the main body case 51, and the first reservoir portion 65 of the dust collection cup 52 which can be attached to and detached from the main body case 51 is formed inside. The open upper end side (one end side) is inserted into the cup body 111 to form a part of the communication air passage 69 and the first centrifugal separation part integrally with the separation body part 115 constituting the first centrifugal separation part 61 When the dust collection cup 52 is removed from the main body case 51 when disposing of the dust in the first reservoir 65 and the second reservoir 66 by covering the cover 61 detachably with the cover 61 in a removable manner, the dust can be collected. Since the dust cup 52 is constituted only of the cover portion 114 integral with the cup portion main body 111 and the separation body portion 115, the dust collection cup 52 is lightweight and easy to handle, and the first reservoir 65 (and the second reservoir Since the upper part of the part 66) is covered by the cover part 114, dust is accidentally removed during disposal. Or mother and child, it is difficult or not Maiagara.

  Moreover, since the cover portion 114 is not a simple lid that covers the upper end side of the cup portion main body 111, but is for partitioning a part (upstream side) of the communication air passage portion 69, the cover portion 114 has a plurality of common components. And the structure can be simplified.

  That is, in the present embodiment, when configuring the main body case 51 and the dust collection cup 52 which is attachable to and detachable from the main body case 51, the wall portion divided by these can be appropriately selected. A cover that covers a portion of the essential configuration (the communicating air passage 69) without requiring a separate new configuration (the first reservoir 65 (and the second reservoir 66)) Since the present invention can be used as the configuration 114, it is possible to realize the configuration for reliably preventing the spillage and the rise of dust at the time of disposal with a simple configuration (low cost).

  Further, since the second reservoir 66 for storing the dust centrifugally separated by the second centrifugal separator 62 is formed between the cup body 111 and the cover 114 attached to the cup body 111, Even when the dust cup 52 is removed from the main body case 51, the second reservoir 66 can be covered by the cover 114 attached to the cup body 111, and the inside of the second reservoir 66 can be removed when dust is discarded. Dust is less likely to spill or soar. In particular, fine dust, which is relatively small dust, is stored in the second reservoir 66, and such fine dust is easily thrown up, so that the cover 114 covers the upper side of the second reservoir 66, Soaring of fine dust can be reliably prevented.

  Furthermore, since the first reservoir 65 and the second reservoir 66 are partitioned in the state where the cover 114 is attached to the cup body 111, the second reservoir is generated by the negative pressure generated by the drive of the electric blower 53. The dust (fine dust) stored in the portion 66 is not circulated to the first storage portion 65 (first centrifugal separation portion 61), and the dust may be reliably stored in the second storage portion 66. it can.

  And since the suction port 125 which sucks dust-containing air inside with the electric blower 53 is provided with the check valve 126 which can be opened only in the suction direction of dust-containing air, the check valve 126 is the suction port 125. When the dust in the first reservoir portion 65 which tends to spill out of the housing is blocked and the dust is discarded, it is possible to reliably prevent the dust retained in the first reservoir portion 65 from spilling out from the suction port 125. In particular, in the present embodiment, the suction port 125 faces downward in a state where the vacuum cleaner 11 is placed vertically on the charging device 12, and the suction port 125 is provided with the check valve 126. When the dust collection cup 52 is removed while the charging device 12 is placed in the charging device 12, it is possible to reliably prevent the spilling of dust from the suction port 125.

  Moreover, the valve body 128 of the check valve 126 is fixed to the cup body 111 by the fixed body 131 at the upper side and on the central axis side of the cup body 111, so that the outer side portion or the lower side is Since it deforms in an inclined manner so as to open, dust-containing air sucked into the first centrifugal separation unit 61 from the introduction unit 113 (introduction air passage unit 68) is rectified by the valve body 128 and the inner periphery of the cup unit main body 111 Guided along a direction tangential to the surface. Therefore, the dust-containing air is easily swirled in the cup portion main body 111, and the efficiency of the centrifugal separation in the first centrifugal separation portion 61 can be improved, and the separated body portion in which the dust containing air is positioned coaxially with the cup portion main body 111 It becomes difficult to spray directly to 115, and adhesion of dust to the separation filter 165 can also be suppressed.

  Then, since the holder on which the vacuum cleaner 11 is placed is the charging device 12 for charging the secondary battery 174, special operations etc. are required only by placing it on the charging device 12 in order to store the vacuum cleaner 11. Thus, the secondary battery 174 can be charged easily and reliably. Therefore, the secondary battery 174 can be charged even while performing maintenance work such as removing the dust collection cup 52 and the filter 63 from the main body case 51 of the vacuum cleaner 11 placed in the charging device 12 and discarding dust and the like. The time during which the secondary battery 174 is charged next can be used effectively, and it is easy to use.

  In addition, although the charging circuit was incorporated in the vacuum cleaner 11, it can also be incorporated in the holding part 188 of the charging device 12, etc.

  While 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. This novel embodiment can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
