Further, the bag-like filter 2 is provided with a mouth frame 6 made of synthetic resin and having a suction port 5, and around the suction port 5 of the mouth frame 6, an original mouth frame backing 7 made of rubber is provided. is provided. Conventionally, a structure has been adopted in which the mouth frame 6 is disposed on the opposite side of the bag-shaped filter 2 from the dust disposal opening 3. J3, both corners of the bag-shaped filter 2 on the mouth frame 6 side are rounded to prevent dust 8 from remaining, and both corners of the bag-shaped filter 2 on the dust disposal opening 3 side are rounded. , Preventing dust 8 from remaining and preventing dust 8 from remaining when the fastener 4 is not completely tightened.
An inclined seam 9 is provided to prevent leakage.

Moreover, as shown in FIG. 12, the above! The vacuum cleaner main body 11 has a dust collection chamber 10 in which the Iu bag 1 is removably attached on the inside front side, and an electric transport T5i machine (not shown) is disposed inside the rear side, and an IyI dust collection A lid body 12 that covers the chamber 10 in an openable and closable manner is pivotally attached to the upper front side. Furthermore, a spout holder 13 to which the spout 6 of the moeki collection bag 1 is removably attached is pivoted to the front part of the dust collection chamber 10.

Then, the dust disposal opening 3 is closed with the fastener 4! When the bag 1 is placed in the dust collecting chamber 10 for cleaning, dust 8 is introduced into the bag-like filter 2 from the suction port 5 of the mouth frame 6 and is captured. Further, the air filtered through the bag-shaped filter 2 is sucked into the electric blower that is being driven.

At this time, in the conventional structure described above, since the bag-shaped filter 2 has the dust disposal opening 3 on the opposite side of the mouth frame 6, this opening 3 is located inside the dust collection chamber 10 and on the side of the electric blower, that is, on the side of the electric blower. Located in the area with the highest wind speed near the electric blower.

Since the dust disposal opening 3 is located at a position where the suction action of the electric blower is directly applied, this opening 3
Even if the slide fastener 4 is closed, depending on the structure of the fastener 4, the small groove-like gap that exists between the mutually engaged engaging bodies of the slide fastener 4 may
Dust may leak.

In addition, when disposing of dust, after removing the collection bag 1 from the fish collecting space 10, as shown in FIG. The dust 8 in the bag-shaped filter 2 is dropped into the dust box 14 through the opened frontage 3 with the opening 3 facing down.

By the way, when opening the dust disposal opening 3, the dust disposal opening 3 must be positioned on the upper side in order to operate the fastener 4. However, in the above conventional structure,
At this time, the mouth frame 6 located on the opposite side of the opening 3 is located on the lower side, and the mouth frame 6 located at the bottom of the filled bag-like filter 2
The suction port 5 is directed outward and downward. Therefore,
Through this suction port 5, a considerable amount of thin liquid falls from inside the seat bag-shaped filter 2.

In addition, FIGS. 13 to 15 show other examples of the conventional dust collection bag for electric h1 remover. A mouth frame 6 is provided at the position, and the mouth frame 6 has a structure in which a rubber valve body 16 having a radial cutout 15 and which can be freely opened and closed is provided, as shown in FIG.

However, even with this conventional structure, when opening the frontage 3 with the dust disposal opening 3 facing upward, the valve body 16 is slightly weighed down by the load of the dust 8, as shown in FIG. After all, especially fine dust leaks from the suction port 5.

Further, the valve body 16 opens and closes as the insertion pipe at one end of the suction hose is inserted into and removed from the suction port 5.
6 imposes a considerable load on the insertion and removal of the insertion tube, resulting in poor operability in insertion and removal of the insertion tube, and in some cases, the insertion tube may become unmanageable.

(Problems to be Solved by the Invention) As mentioned above, in the conventional four-bag vacuum cleaner collection bag, the dust disposal opening and the suction port are arranged in opposite positions in the bag-like filter. Therefore, when opening the opening to dispose of dust, dust may leak from the suction port, and during cleaning, fine dust may leak from this opening even if the VU disposal opening is closed. There was a problem.

The present invention aims to solve these problems, and aims to prevent a
It is an object of the present invention to provide a dust collection bag for an electric dehydrator that can prevent the leakage of dust from the suction port when opening and closing the dust disposal opening. Another object of this dust collection bag for a vacuum cleaner is to enable the dust in the bag-shaped filter to be easily discarded.

Note that this mouth frame 57 and the slide fastener 54 are
In order to secure the space necessary for machine sewing the base fabric of the slide fastener 54, a slight distance n1 is provided. A circular suction port 58 that communicates the inside and outside of the bag-shaped filter 52 is formed in the center of the mouth frame 57. This suction port 58 is into which the distal end of the insertion tube 42 of the boss is removably inserted.

Further, a mouth frame backing 59 in the form of an annular thin film made of rubber or the like and having flexibility is fixed to the mouth frame 57 located at the peripheral edge of the suction port 58. The inner diameter of this mouth frame backing 59 is slightly smaller than the outer diameter of the insertion tube 42.

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

To install the dust collection bag 51 into the dust collection chamber 25 of the vacuum cleaner main body 21, as shown in FIG.
Slide the bag-shaped filter 52 of the dust collection bag 51 into the slide fastener 5A.
[f: Place the bag 51 into the dust chamber 25 with the closed dust disposal opening 53 facing upward, and attach the mouth frame 57 of the bag 51 to the mouth frame boulder 37. After that, the lid body 24 is closed.

At this time, since the dust disposal opening 53 is located near the mouth frame 57, the dust disposal opening 53 is exposed upward in the dust collection chamber 25 that opens upward. Therefore, if the slide fastener 54 is forgotten to be tightened, the user will easily notice this. Therefore, there is little possibility that the dust disposal opening 53 will be used with it open.

When cleaning, the vacuum cleaner body 21, hose 41 and extension pipe 45 are
and the suction port body 46 are connected to each other. In particular, the insertion tube 42 of the hose 41 is inserted into the connection port 26 of the vacuum cleaner body 21, but at the same time, the insertion tube 42 is inserted into the suction port 58 of the mouth frame 57 facing the connection port 26. The tip end is inserted, and the mouth frame backing 59 is brought into airtight contact with the outer peripheral surface of the insertion tube 42.

Then, the dust 61 sucked together with air from the dust suction port of the suction port body 46 by the drive of the electric blower inside the vacuum cleaner main body 21 passes through the extension pipe 45 and the hose 41, and then passes through the insertion pipe of the hose 41. 42 into the inside of the bag-like filter 52, and 1iIi is trapped there. In addition, the air filtered by the bag-like filter 52 passes through a sub-filter and is further purified, and then passes through an electric blower to the exhaust port 33.
is discharged from.

At this time, the dust disposal opening 53 is located near the suction port 58 in the bag-shaped filter 52, that is, on the upstream side, and is therefore located away from the electric blower in the dust collection chamber 25. Therefore, the strong suction action of the electric blower is not directly applied to the dust disposal opening 53, so that a slight gap is created between the engaging bodies when the slide fastener 54 that closes this opening 53 is tightened. Even if it is, fine dust will not leak from this slide fastener 54.

For small cleaning, the vacuum cleaner body 21, hose 41 and extension pipe 45 are used.
and the suction port body 46 are removed from each other and stored.

In particular, when pulling out the insertion tube 42 of the hose 41 from the connection port 26 of the vacuum cleaner main body 21, the mouth frame backing 59 is attached to the insertion tube 42.
This insertion pipe 42 is inserted into the mouth frame 5 while
It can be handled from the suction port 58 of No.7. At this time, the annular mouth frame backing 59 does not place much load on the insertion tube 42 when it is removed or removed compared to the valve body 16 having the cut groove 15, so the insertion tube 42 can be easily handled. Moreover, this insertion tube 42 will not become unmanageable. Also, the same applies when inserting and removing the insertion tube 42, and the opening frame backing 5
Since the load on the tube 9 is not so great, the insertion tube 42 can be easily inserted.

In addition, in order to discard the dust 61 accumulated in the bag-like filter 52 of the bag 51, first, as shown in FIG.
4, and while removing the mouth frame 57 from the mouth frame holder 37, remove the dust collection bag 51 from inside the collection rfj box 25.

Next, as shown in FIG. 1, with the dust disposal opening 53 of the bag-shaped filter 52 facing upward, the opening/closing knob 55 of the slide fastener 54 is operated to open the dust disposal opening 5.
Open 3.

At this time, the suction port 58 near this opening 53 is also located on the upper side, and the suction port 58 is located at the top of the bag-shaped filter 52 that is swollen due to dust, and the suction port 58 faces upward toward the outside. The dust 61 inside the bag-shaped filter 52 hardly leaks from the bag-shaped filter 58. Furthermore, since there is no need to lay down the bag-shaped filter 52 and open the opening 53 in order to prevent dust from leaking from the suction port 58, the opening operation can be performed easily.

Next, as shown in FIG. 2, the bag 51 is turned upside down so that the opened dust disposal opening 53 faces downward, and the inside of the bag-shaped filter 52 is exposed through the opening 53, for example, with a whistle. Dust 61 is caused to fall into 62.

Thereafter, the dust disposal opening 53 is closed again with the slide fastener 54, and the O collection bag 51 is closed as described above.
Collect! ! ! iInstall it in the sky 25.

Thus, according to the above configuration, by arranging the dust disposal opening 53 and the suction port 58 in the vicinity of each other, the dust
The dust collecting bag 51 is easy to use and has little leakage. Furthermore, in order to prevent the leakage of dust 61 from the suction port 58 when disposing of dust, there is no need to provide a valve body in the suction port 58, so that the insertion and removal of the insertion pipe 42 of the hose 41 is easy as described above. It can be done easily.

In the above embodiment, the opening/closing means for the dust disposal opening 53 is the slide fastener 54, but the opening/closing means may be a fastener consisting of a removable protrusion and groove, or a fastener that extends in the axial direction and opens the dust disposal opening 53. A clip made of an impact vibrator having a groove for tightening the opening 53 may be used.

In addition, a disposable dust collection bag consisting of a breathable paper bag-shaped filter and a cardboard mouth frame having a suction port is installed in the dust collection chamber 25 of the vacuum cleaner main body 21 of the above embodiment. It can also be used as
