A cylinder section 91 is provided. A filter 93 having air permeability is detachably attached to the upper surface of the lid 86 so as to close the air collecting cylinder 89.

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

First, the lid 24 is removed from the case 23,
A dust collecting body 80 having a lid 86 previously attached to the dust collecting cup 82 is engaged with and mounted on one end side of the bottom plate 27 of the case body 23 in the mounting concave portion 81. Thereafter, the lower surface of one end side of the lid 24 on which the lattice portion 61 is provided is brought into contact with the upper end of the dust collector 80, and the upper portion of the case 23 is sandwiched between the case 23 and the lid 24. The cover 24 is integrally attached to the cover. And
The base end of the hose 72 is connected to the connecting portion 73 of the suction section 68, and the suction port is connected via an extension pipe (not shown) as appropriate, to be in a cleaning standby state. Note that accessories may be connected instead of the suction port body, or accessories may be connected instead of the extension pipe and the suction port body.

In the cleaning standby state, the electric blower 40 is appropriately driven and cleaned by operating the operating means of the cleaner main body 21 and the hand operating means of the gripping portion provided at the tip of the hose 72. When the hose 72 is not connected and the cleaning standby state is not established, the control unit mounted on the circuit board 44 operates the electric blower even if the operating unit is operated to prevent unnecessary use of electric power. Control not to drive 40.

Then, dust is sucked in together with air from a floor suction port (not shown) opened on the lower surface of the suction port body. The sucked dust is sucked into the suction part 68 via the extension pipe and the hose 72, and passes through the penetrating part 70 of the suction part 68 to collect dust.
The air is drawn into the dust collecting cup 82 in a spiral form from the intake cylinder portion 91 of 80. Then, the dust falls along the inner surface of the dust collection cup 82 due to the centrifugal force of the vortex, and the air flows out of the center of the vortex from the air collection cylinder 89 of the lid 86 of the dust collector 80, and the air and the dust are removed. Are separated. Further, the separated air passes through the intake passage 65 from the through hole 60 of the lattice portion 61 after the fine dust mixed without being separated by the filter 93 attached to the lid portion 86 of the dust collecting body 80 is removed. Then, the air is blown from the intake port of the electric blower 40 through the communication hole 37. Further, the air passes through the inside of the electric blower 40 and is exhausted into the electric blower room 41, and is further exhausted to the outside air through the exhaust hole.

After the electric blower 40 is stopped by the setting operation of the operating means and the hand operating means to complete the cleaning, the lid 24 is removed from the case body 23 and the dust collecting body 80 is removed.
Is removed from the case body 23. Then, the lid 86 of the dust collecting body 80
Is removed from the dust collection cup 82 and discharged.

On the other hand, when the cleaning place is changed, for example, when the cleaner body 21 is carried to clean the next room, or when the cleaner body 21 is to be cleaned while holding the cleaner body 21 in a place where the cleaner body 21 cannot travel, such as a staircase. For example, when carrying to the storage place and storing it in a predetermined position in the storage place, the cleaner main body 21 is lifted by grasping the first handle 76 or the second handle 77, 77 of the handle means 75.

Here, the first handle 76 and the second handle 7
Since the axes 7 and 77 have different axial directions, it is only necessary to select and grip a position that the operator can easily hold when gripping.

In the above embodiment, the first handle 76 and the paired second handle 76 centered on the center of gravity G of the cleaner main body 21.
Since the handles 77, 77 are provided radially, it is only necessary to select and grip a portion that the operator can easily hold, so that the main body case 25 can be easily carried and the cleaning workability can be improved.

Further, the handle means 75 is substantially symmetrical with the first handle 76 and the first handle 76 using the first handle 76 as an axis of symmetry.
The second handle 7 that is connected to form a pair
7 and 77 are integrally provided, and a handle means 75 is formed in a substantially Y shape so that the first handle 76 is provided along the front-rear direction on the cleaner body 21 provided with the suction portion 68 on the front side. The first handle 76 is positioned above the center of gravity G even if the position of the center of gravity G moves forward from the position of the center of gravity G when only the cleaner body 21 is connected. Since it is located, even if the center of gravity G moves according to the cleaning mode, it can be gripped at a position above the center of gravity G, and the cleaner body 21 can be stably lifted, thereby improving workability.

Further, the handle means 75 is provided on the lid 24 which is removed from the case body 23 in order to discharge the collected dust. Therefore, a separate handle for removing the lid 24 from the case 23 is provided in order to discharge the dust. There is no need to use the handle means 75, and the structure can be simplified.

In the above-described embodiment, a canister-type cleaner main body that captures dust absorbed by centrifugal force.
Although the handle means 75 is provided on the 21, any type of vacuum cleaner, such as one that captures dust with a dust collection bag and a handy type that does not have the driven wheel 28 or the running wheel 35, can be applied.

The handle means 75 includes a first handle.
The second handle 77 is not limited to the structure in which the second handle 77 is branched in a substantially Y-shape, but may be any shape such as a structure in which the second handle 77 is branched in a substantially T-shape. Further, a first handle 76 and a paired second handle 76
The structure is not limited to three branches 77 and 77, and may be any structure in which three or more handles are radially provided.

[0037]

According to the first aspect of the present invention, there is provided a handle having a plurality of handles whose distal ends are connected to the main body case in a radial manner with a center substantially above the center of gravity of the main body case. It is only necessary to select and hold one of the handle means which is the easiest to grasp by the user, and the main body case can be easily carried and the workability can be improved.

According to the vacuum cleaner of the second aspect, in addition to the effect of the vacuum cleaner of the first aspect, the first handle has an axial direction along the front-rear direction of the main body case having the suction portion at the front portion. By providing a pair of second handles, one end of which is connected to the first handle substantially symmetrically with the first handle as a symmetric axis, with the front-rear direction and the axial direction intersecting with each other in the main body case,
For example, even when the center of gravity moves due to the connection of the hose when carrying the main body case with the hose connected thereto, the first handle is located on the center of gravity and can be gripped at a position substantially above the center of gravity, which is different from the first embodiment. However, it can be easily gripped and workability can be improved.
