[0030]
Next, the operation of the vacuum cleaner 10 will be described.
[0031]
To use the vacuum cleaner 10, first, the lid 30 is turned upward, and then the empty dust container 40 is placed on the container mounting recess 60. At this time, the dust collection container 40 can be easily positioned by fitting the lower end portion of the grip portion 44 into the notch portion 63 provided on the peripheral wall 62 of the container mounting concave portion 60. Further, the peripheral wall 62 prevents the container main body 41 from being displaced, and can be securely fitted and mounted on the container mounting concave portion 60.
[0032]
Then, the lid 30 is rotated downward, and the dust container 40 is sandwiched between the lid 30 and the container mounting recess 60. In this state, a switch (not shown) provided on the hand operation pipe 13 is turned on to drive the electric blower 23. At this time, the electric power stored in the battery pack 26 is used.
[0033]
When the electric blower 23 is driven, the air containing dust enters the suction unit 43 from the suction port body 15 through the extension pipe 14, the hand operation pipe 13, the dust collection hose 12, the connection pipe 32, and the communication port 33. Then, while being spirally guided by the guide plate 43 b of the suction part 43, the vortex flows along the inside of the container main body 41 and reaches the bottom of the container main body 41. The dust in the vortex is separated from the air by centrifugal force, and the separated dust is accumulated at the bottom of the container body 41. In particular, if the dust is relatively light, such as cotton dust, the dust is compressed by the sequentially flowing air.
[0034]
The air separated from the dust at the bottom of the container body 41 flows into the connection air passage 34 from the upper opening of the container body 41 via the filter member 42. When air passes through the filter member 42, fine dust that cannot be completely separated in the container body 41 is captured by the filter member 42.
[0035]
Then, the air in the connection air passage 34 passes through the intake air passage 36 to the rear air passage 35, and flows into the intake air passage 28 via the intake portion 27 formed in the main body case 20. At this time, the fine dust in the air is filtered by the filter device 27a. Further, after the air is sucked into the electric blower 23, the air is exhausted from the exhaust port 23a into the atmosphere through an exhaust hole (not shown).
[0036]
On the other hand, when a certain amount of dust is accumulated in the dust collection container 40, first, an open / close button 32a provided on the lid 30 is pressed to release a lock mechanism (not shown), and the lid 30 is turned upward. Move. Then, the dust container 40 is lifted up with the grip portion 44, and the dust container 40 is removed from the container mounting recess 60. Then, as shown in FIG. 5, the bottom cover 45 is opened by operating the opening / closing mechanism 46 provided inside the grip portion 44, and the dust is discarded from the lower opening of the container body 41.
[0037]
In order to operate the opening / closing mechanism 46, first, the upper end of the lock release member 46a protruding from the upper end of the grip portion 44 is pressed downward while resisting the first spring 46b.
[0038]
When the unlocking member 46a moves downward, the lower end of the unlocking member 46a abuts on the upper portion of the locking member 46c, and the upper portion of the locking member 46c of the cleaner body 11 is pressed against the second spring 46e. Move backward. This causes the locking member 46c to rotate clockwise (in FIG. 5) about the rotation shaft 46d.
[0039]
When the locking member 46c rotates clockwise, the locking piece 45a of the bottom cover 45 locked at the lower portion of the locking member 46c is released, and the bottom cover 45 is rotated counterclockwise around the hinge 47. (In FIG. 5).
[0040]
Thereby, the lower opening of the container body 41 of the dust container 40 is opened, and the dust can be easily discarded as shown in FIG. Further, since it is only necessary to push down the upper end of the unlocking member 46a, the hand is not stained.
[0041]
Further, in order to clean the container mounting concave portion 60 in which the dust collecting container 40 is fitted and mounted, after removing the dust collecting container 40 as described above, the cleaning is performed by wiping the container mounting concave portion 60 with a cloth or the like. Do. At this time, since the container mounting surface 61 of the container mounting concave portion 60 has a planar shape, the container mounting surface 61 can be easily wiped, and dust attached to the container mounting concave portion 60 can be easily removed.
[0042]
In particular, in the case of the dust collecting container 40 in which the bottom cover 45 is opened and dust is discarded as described above, the peripheral portion and the like of the bottom cover 45 are easily soiled, and the container mounting recess 60 is often soiled. However, since the container mounting surface 61 of the container mounting concave portion 60 has a flat shape and is easily wiped, it is easy to always keep the container clean.
[0043]
Since the notch 63 provided on the peripheral wall 62 of the container mounting recess 60 reaches the container mounting surface 61, the notch 63 adheres to the container mounting surface 61 from the notch 63 toward the outside of the cleaner body 11. It can also sweep out dust.
[0044]
In addition, since the container mounting recess 60 having the planar shape is provided in the upper case 21, the container mounting surface 61 of the container mounting recess 60 regardless of the shape of the lower case 22 located below the container mounting recess 60. Can have a planar shape.
[0045]
For this reason, as described above, the swelling portion 64 is formed in the lower case 22, and the slewing ring 50 is arranged in the slewing ring installation chamber 65 formed inside (lower side) of the swelling portion 64. The container mounting recess 60 can be positioned above the bulging portion 64.
[0046]
As described above, one embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above-described embodiment, and there are design changes and the like that do not depart from the gist of the present invention. Is also included in the present invention.
[0047]
For example, the container mounting surface 61 of the container mounting recess 60 may be covered with an ion generating sheet that generates negative ions. Thereby, when the dust collecting container 40 is fitted and mounted in the container mounting concave portion 60, the ion generating sheet is interposed between the dust collecting container 40 and the container mounting concave portion 60, and the dust adheres to the container mounting concave portion 60. Can be prevented.
[0048]
Further, if the ion generating sheet is detachably provided, the container mounting recess 60 can be cleaned only by replacing the ion generating sheet.
[0049]
Note that the container mounting recess 60 is not limited to the ion generating sheet, but may be a general vinyl sheet, cloth, or the like.
