As shown in FIGS. 2 and 6, when the paper pack 4 is set in the basket 5, the fixing plate 10 fixed to the paper pack 4 may be fitted between the groove 15 and the clamp 17. Conversely, when the paper pack 4 is taken out and discarded, it is only necessary to rotate the clamp 17 upward.

In this embodiment, since the outlet 9 is formed on the rear surface of the basket 5, the paper pack 4 mounted inside the basket 5 can be easily discarded by the natural fall through the outlet 9. As a result, convenience is improved. In addition, even if the paper pack 4 is swollen by dust or the like and becomes almost full, the paper pack 4 is stuck on the four side walls (the rear wall 8, the side wall 11, and the front wall 12 in the case of the basket 5 in FIG. 2) and cannot be removed. No defects.

In the present embodiment, an example has been described in which the outlet 9 is formed on the rear surface, but the present invention is not limited to this, and the outlet 9 is formed on the side. In the same manner as described above, the paper pack 4 can be easily taken out of the basket 5 through the outlet 9 and discarded.

The front wall 12 of the basket 5 is formed with a connection port 13 communicating with the suction port 1a of the cleaner body 1, and a packing 14 is provided on the periphery of the connection port 13.

When the ring portion 14a contacts the fixed plate 10 without any gap, the space between the front wall 12 and the fixed plate 10 is hermetically sealed. At the same time, the ring portion 14d comes into contact with the inner wall of the dust collecting chamber 3 without any gap, thereby hermetically sealing the space between the inner wall of the dust collecting chamber 3 and the front wall 12.

Further, as shown in FIGS. 3 and 6, the basket 5 is provided with a rib 5a for receiving the semicircular maximum outer peripheral portion 14e of the ring portion 14d of the packing 14, so that the ring portion 14d is provided. It can prevent turning over and catching.

In the present embodiment, since a vertical wall (rear wall 8) is formed at the lower opening edge of the outlet 9 of the basket 5, fine dust and the like are not collected in the paper pack 4 but are collected in the basket 5. Even if it accumulates, the dust and the like are guarded by the rear wall 8, so that fine dust does not spill when the paper pack 4 is discarded (the basket 5 is tilted).

The height of the rear wall 8 (in other words, the size of the outlet 9) is not particularly limited in the present invention. It is sufficient if it is left so that it does not catch.

When the outlet 9 is formed in the side wall 11, dust and the like do not spill into the dust collecting chamber 3 as described above, except for the vicinity of the lower end of the side wall 11.

In this embodiment, the outlet 9 is formed on the rear surface (that is, on the side closer to the electric blower 2), so that the outlet 9 is provided between the electric blower 2 and the paper pack 4. By communicating, suction performance can be improved.

Further, in the present embodiment, the basket 5
A handle 16 and the clamp 17 are provided on the front wall 12 of the vehicle. Specifically, a handle 16 having an arched shape is fixed to the front wall 12 of the basket 5 by claws 18 (see FIG. 3) projecting downward from both ends of the handle 16. Inside the space surrounded by the handle 16,
The clamp 17 has a pair of shafts 19 projecting from both sides.
(See FIG. 3).
As shown in FIG. 6, the clamp 17 is constantly urged by a spring 20 in a direction to clamp the fixed plate 10.

With such a structure, when the paper pack 4 is discarded, it is performed as follows. First, with the paper pack 4 attached to the basket 5, the basket 5 is pulled out from the cleaner body 1 with the handle 16, and while holding the handle 16 by hand, the clamp 17 on the front wall 12 is rotated upward. Remove it. In the present embodiment, since the rear surface of the box-shaped basket 5 is the outlet 9, and the handle 16 is attached to the front end of the basket 5, the back of the basket 5 is lowered when the handle 16 is held. As a result, paper pack 4
Can be easily disposed of by natural fall. Therefore, the paper pack 4 can be easily discarded without turning the basket 5 upside down while holding the handle 16 by hand. Further, the clamp 17 can be operated with one hand with the hand holding the handle 16, which is convenient.

On the other hand, when replacing the paper pack 4,
The paper pack 4 is mounted on the basket 5 outside the cleaner main body 1, and then the basket 5 can be easily mounted on the cleaner main body 1 by holding the handle 16.

Also, as shown in FIG.
Is located at the forefront side (front wall 12 side) of the basket 5, when the basket 5 attached to the cleaner body 1 is pulled up, the basket 5 is positioned behind the basket 5 due to the center of gravity of the basket 5. The side (the rear wall 8 side) tilts downward. As a result, the suction port 21 of the paper pack 4 faces upward, so that dust and dust are less likely to leak when the basket 5 is transported.

In addition, since the clamp 17 is rotated while the rear side of the basket 5 is tilted as described above, the paper pack 4 is discarded through the outlet 9 on the rear side of the basket 5.
The paper pack 4 can be easily dropped.

As described above, the handle 16 of the basket 5
By providing the clamp 17, it is possible to improve the convenience of taking out, attaching, and transporting the basket 5 and attaching and discarding the paper pack 4.
Moreover, in the conventional basket, a rubber packing for preventing dust from leaking is provided at a peripheral edge of an upper end of the basket so that dust can be collected without a paper pack. Since it is intended to be used with
Further, attachment and detachment become easy.

Further, in the related art, when a basket with a filter is used without a paper pack, the suction performance is reduced due to clogging of the filter due to dust or the like. In the present embodiment, the suction performance is prevented from lowering. As shown in FIGS. 2 and 4, at least one ventilation opening 22 is formed in at least the side wall 11 of the basket 5 on the assumption that the paper pack 4 is used.

The present invention does not particularly limit the shape, number and arrangement of the ventilation openings 22. Therefore, the shape of the opening 22 may be a round hole as shown in FIG. 4 or a square hole. As shown in FIG. 4, the number of the openings 22 may be such that about 16 small-diameter holes are formed in each side wall, or one large-diameter hole is formed in each side wall 11 and the periphery of the hole is formed. A reinforcing rib may be formed on the base.
Furthermore, as for the arrangement of the openings 22, as shown in FIG. 4, a plurality of openings 22 may be regularly arranged up, down, left, and right,
They may be distributed.

As shown in FIG. 8, a slight gap 24 is formed between the basket 5 and the inner side wall 23 of the dust collecting chamber 3 of the cleaner body 1. Therefore, the opening 22 of the side wall 11 of the basket 5 communicates with the electric blower 2 through the gap 24 and the exhaust port 3b. With this configuration, a flow path of air to the opening 22 is secured, so that the air can be uniformly sucked into the inside of the paper pack 4 and dust can be collected not only on the rear surface but also on the side surface of the paper pack 4, and the suction performance is reduced. Can be prevented.

The opening 22 can be formed in the bottom wall 25 of the basket 5 shown in FIGS. 2 and 7 to 8. In this case as well, a decrease in suction performance can be prevented as described above. Instead of forming the opening 22 in the wall 25, FIG.
And the paper pack 4 and the bottom wall 2 as shown in FIGS.
By protruding the planar protrusion 26 to prevent the close contact with 5,
Deterioration of suction performance can be prevented without dust or dust spilling from the basket 5 to the dust collection chamber 3.

As described above, the vacuum cleaner of the type in which the filter is attached to the basket without using the conventional paper pack by using the paper pack 4 and providing the ventilation opening 22 and the planar protrusion 26. As compared with, the filter is not clogged, the suction performance can be prevented from lowering, and the number of parts can be reduced to reduce the cost.
