Further, the air that has passed through the communication air passage portion 69 flows into the second centrifuge portion 62 through the suction opening 103, and is along the inner peripheral surface of the separation cylinder portion 94 in the second centrifuge portion 62. It is swirled and the fine dust is further centrifuged. The separated fine dust falls from the dust discharge port 106 at the lower end of the separation cylinder portion 94 to the second reservoir 66 in the dust collection cup 52 and is collected. The air from which the fine dust is 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) that remains slightly after passing through the lower air passage 179 is filtered and collected by the filter 63, and is further sucked from the suction opening 96 into the intake port 53a of the electric blower 53.

Then, the air sucked into the electric blower 53 passes through the electric blower 53 while cooling and becomes exhaust air, and after being discharged from the exhaust port into the electric blower room 91, the lower part of the electric blower room 91. While being rectified by the smooth inner peripheral surfaces of the exhaust section 162 and the exhaust stack section 122 from the exhaust opening 100 of the above, it passes downward through the inside of the separator section 115 to the outside of the dust collecting cup 52 (main body section 16). Is discharged, and is guided to each exhaust opening 171 while being dispersed by each rib 123, and is dispersed and exhausted along the radial direction from these exhaust openings 171.

When the cleaning is completed, the user operates the setting button 89 to stop the electric blower 53, install the vacuum cleaner 11 in the charging device 12, store it, and charge 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 holding portion 196 from above to lock and hold the hook portion 33.

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

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

The locking clamp 107 that locks the lid 74 to the case body 73 is exposed above the inclined portion 193a while being operably exposed to the upper part of the dust cup 52, and the clamp 117 and the locking clamp 107 can be operated respectively. (Fig. 1). Therefore, by operating the clamp 117 and the locking clamp 107, the dust collecting cup 52 and the lid 74 can be removed from the main body case 51 with the introduction portion 113 as a fulcrum.

When the charging device 12 recognizes the installation of the vacuum cleaner 11 via the terminal portion 198 or the like, the charging device 12 supplies the electric power supplied from the external power source via the power adapter 181 to the charging circuit of the vacuum cleaner 11 by the terminal portion 198. The charging circuit is driven, and this charging circuit charges the secondary battery 174. In the charging circuit, for example, the charging state of the secondary battery 174 is monitored, and when it is confirmed that the secondary battery 174 is in a predetermined charging state (fully charged), charging is stopped.

When disposing of dust, from the state shown in FIG. 1, the dust collecting cup 52 is moved to the main body case 51 (from the state shown in FIG. 1 by operating the clamp 117 with the non-slip portion 121 held by the cup portion main body 111. Remove from the mounting opening 77). That is, in the vacuum cleaner 11 mounted on the charging device 12, the dust collecting cup 52 whose axial direction is the horizontal direction intersecting (orthogonal) with respect to the vertical direction which is the longitudinal direction of the main body case 51 is the axis of the dust collecting cup 52. It is removed while rotating backward along the horizontal direction, which is the direction, with the introduction portion 113 as a fulcrum. At this time, the dust collecting cup 52 is in a state where the suction port 125 faces downward, but the check valve 126 is in a state where the negative pressure of the electric blower 53 is not acting, and the outer edge of the front portion of the valve body 128 is not acting. Since the portion is in contact with the regulation portion 129, dust is discharged from the lower side of the valve body 128, which is the side opposite to the cup portion main body 111 (the anti-cup portion main body 111 side), that is, the first reservoir 65. It does not open downward and does not allow dust in the first reservoir 65 to spill out from the suction port 125 through the introduction portion 113. Further, in the dust collecting cup 52 removed from the main body case 51, the cover portion 114 is attached to the cup portion main body 111, so that the upper portions of the first reservoir portion 65 and the second reservoir portion 66 are respectively covered by the cover portion 114. Covered and contained dust does not fly up. Further, even if dust adheres to the cover portion 114, the dust falls to the holding portion 188 side, so that the dust does not fall to the mounting surface (cleaned surface). In this state, the user carries the dust collecting cup 52 to a disposal position such as a trash can, picks the knob portion 146, and removes the cover portion 114 from the cup portion main body 111. At this time, since the knob portion 146 is located in the space portion 148 outside the air passage that communicates with the suction side of the electric blower 53, it is not in contact with dust-containing air, and is in a clean state without dust adhering to it. Because it keeps the air, the user's hands will not get dirty. Then, the user turns the cup portion main body 111 upside down and discharges the dust of the first reservoir 65 and the second reservoir 66 from the dust disposal port 118. Further, the cover portion 114 removed from the cup portion main body 111 is removed by sliding the brush body 152 attached to the upper portion of the cover portion 114 upward to separate the separate body portion 115 integrated with the cover portion 114. Care (maintenance) is performed by removing the dust adhering to the filter 165 and the compression filter 167, or the dust adhering to the surface of the dust receiving portion 112 and the like. After removing the dust, the dust collecting cup 52 can be reattached and used.

Since almost no dust remains in the air after passing through the second centrifuge 62, the filter 63 is not substantially clogged and basically does not require maintenance. , Operate the locking clamp 107 exposed above the holding portion 188 (expanded portion 193) of the charging device 12 to remove the lid 74 from the case body 73 forward to expose the exposed opening 75. Dust adhering to the filter 63 can also be removed by removing (FIG. 3) and tapping.

As described above, in the case of the stick-type vacuum cleaner 11, since it does not stand on its own as it is, it is necessary to temporarily place it on the floor or the like in order to remove the dust collecting cup. Therefore, according to the above-described embodiment, the main body 16 is held by the holding portion 188 in a state where the vacuum cleaner 11 (main body 16) is inserted into the holding portion 188 with the introduction portion 113 facing downward. Since the clamp 117 is mounted on the charging device 12 so as to be operably exposed above the dust collecting cup 52, at least a part of the dust collecting portion 54 by operating these clamps 117, in the present embodiment, the first centrifuge. The dust collecting cup 52 having the separating portion 61 and the reservoir 56 (the first and second reservoirs 65 and 66) inside can be removed from the main body case 51.

Further, with the vacuum cleaner 11 attached to the charging device 12, the lid 74 is located above the holding portion 188 and the locking clamp 107 is also operably exposed. Therefore, the lid is operated by operating the locking clamp 107. The body 74 can be removed, and the filter 63 arranged on the suction side of the electric blower 53 can be removed from the main body case 51.

Therefore, the dust collecting cup 52 and the filter 63 can be easily removed, and the dust can be easily disposed of.

Further, the cup portion main body 111 in which the electric blower 53 and the second centrifuge portion 62 are arranged in the main body case 51 and the first reservoir portion 65 of the dust collecting cup 52 detachable from the main body case 51 is formed inside. The opened upper end side (one end side) is integrally inserted with the cup portion main body 111 to form the first centrifuge portion 61, and is integrated with a part of the communication air passage portion 69 and the first centrifuge portion. When the dust collection cup 52 is removed from the main body case 51 when the dust in the first reservoir 65 and the second reservoir 66 is disposed of by being detachably covered by the cover portion 114 that separates the 61, this collection Since the dust cup 52 is composed of only the cover portion 114 integrated with the cup portion main body 111 and the separator portion 115, the dust collecting cup 52 is lightweight and easy to handle, and the first reservoir portion 65 (and the second reservoir) 65 (and the second reservoir) are easy to handle. Since the upper part of the part 66) is covered by the cover part 114, it is difficult to accidentally spill or raise dust at the time of disposal.

Moreover, since the cover portion 114 is not a mere lid that covers the upper end side of the cup portion main body 111, but a part (upstream side) of the communication air passage portion 69, the cover portion 114 has a common configuration. Can be formed by, and the configuration can be simplified.

That is, in the present embodiment, when the main body case 51 and the dust collecting cup 52 that can be attached to and detached from the main body case 51 are configured, the wall portion and the like to be divided by these are appropriately selected to form a lid or the like. A cover portion that covers a part of the essential configuration (communication air passage portion 69) with the cup portion main body 111 (first reservoir portion 65 (and second reservoir portion 66)) without requiring a new configuration separately. Since it can be used as 114, it is possible to realize a configuration that reliably prevents dust from spilling and flying up during disposal with a simple configuration (low cost).

Further, since the second collecting portion 66 for collecting the dust centrifugally separated by the second centrifuging portion 62 is formed between the cup portion main body 111 and the cover portion 114 attached to the cup portion main body 111, the dust is collected. 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 main body 111, and the inside of the second reservoir 66 is used when dust is discarded. Dust is less likely to spill or fly up. In particular, fine dust, which is relatively small dust, is accumulated in the second reservoir 66, and such fine dust easily rises up. Therefore, the cover portion 114 covers the upper part of the second reservoir 66. It is possible to surely prevent the flying of fine dust.

Further, since the cover portion 114 is attached to the cup portion main body 111 and the first reservoir portion 65 and the second reservoir portion 66 are partitioned, the negative pressure generated by the drive of the electric blower 53 causes the second reservoir portion. Dust (fine dust) collected in the portion 66 does not circulate to the first reservoir 65 (first centrifuge 61), and the dust can be reliably accumulated in the second reservoir 66. it can.

The check valve 126 is provided with a check valve 126 that allows the suction port 125 that sucks dust-containing air inside by the electric blower 53 to be opened only in the direction in which the dust-containing air is sucked. Therefore, the check valve 126 is the suction port 125. When the dust in the first reservoir 65 that is about to spill from the outside is blocked and the dust is discarded, the dust accumulated in the first reservoir 65 can be reliably prevented from spilling from the suction port 125. In particular, in the present embodiment, since the suction port 125 faces downward in a state where the vacuum cleaner 11 is placed vertically on the charging device 12, the check valve 126 is provided in the suction port 125 to provide the vacuum cleaner 11. Can be reliably prevented from spilling dust from the suction port 125 when the dust collecting cup 52 is removed while the dust collecting cup 52 is placed on the charging device 12.

Moreover, the valve body 128 of the check valve 126 has an outer portion or a lower portion because the position on the upper side and the central axis side of the cup portion main body 111 is fixed to the cup portion main body 111 by the fixed body 131. Since it is deformed in an inclined shape so as to open, the dust-containing air sucked from the introduction portion 113 (introduction air passage portion 68) into the first centrifuge portion 61 is rectified by this valve body 128 and is rectified by the valve body 128, and the inner circumference of the cup portion main body 111 It is guided along the tangential direction with respect to the surface. Therefore, the dust-containing air can easily swirl in the cup body 111, the efficiency of centrifugation at the first centrifuge 61 can be improved, and the dust-containing air is located coaxially with the cup body 111. It becomes difficult to spray directly on 115, and dust adhesion to the separation filter 165 can be suppressed.

And since the stand on which the vacuum cleaner 11 is placed is the charging device 12 for charging the secondary battery 174, it is necessary to perform a special operation just by placing it on the charging device 12 to store the vacuum cleaner 11. The secondary battery 174 can be charged easily and reliably. Therefore, the secondary battery 174 can be charged even during maintenance work such as removing the dust collecting cup 52 and the filter 63 from the main body case 51 of the vacuum cleaner 11 placed on the charging device 12 and discarding the dust. The time until the next battery 174 can be used next can be effectively used, and the usability is good.

Although the charging circuit is built in the vacuum cleaner 11, it can also be built in the holding unit 188 of the charging device 12.

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