Description

[Detailed description of the invention] The present invention relates to a vacuum cleaner.

For dust cases with lids that can be opened and closed, if you open the lid and dump the dust directly from the dust case into a designated area, dust will fly up, so attach a dust collection bag made of polyethylene or other material to the opening edge of the dust case to prevent dust. A method of discarding the bag has been adopted, but since the lid is opened before setting the dust collection bag, the dust is scattered around and is unsanitary.

In addition, even after the dust collection bag is set, the inside of the dust collection bag remains in close contact with the inside of the bag, making it troublesome to expand the volume.Furthermore, most of the dust is cotton-like dust and is extremely light, so the dust inside the dust collection bag is It has the disadvantage that it is difficult to transfer.

This invention solves the above-mentioned drawbacks, and furthermore, stores the dust collection bag in the dust case for convenience when disposing of dust.
Furthermore, it is not intended to be used as a vacuum cleaner to prevent the dust collection bag from adhering to the filter due to negative pressure.

This invention connects a dust case in which a dust collection chamber with an opening on one side is formed to house a filter to a main body case with a built-in electric blower, and attaches a lid to the dust case to open and close the opening of the dust collection chamber. , while the opening edge of the dust collection bag is maintained in an open state by a holder, the dust collection bag is removably attached near the opening edge of the dust collection chamber, and the dust collection bag is housed in the dust collection chamber, and biased in one direction. A pressing plate that presses the dust collection bag against the lid is provided in the dust collection chamber so as to be rotatable in a direction in which the dust collection bag is pushed out while being spread out when the lid is opened. It is something.

Therefore, when you open the lid, the dust collection bag is already set, which eliminates the hassle of looking for the dust collection bag, and since the dust collection bag covers the opening surface of the dust collection chamber, dust can be removed. In addition, when the lid is opened, the holding plate rotates and the dust collection bag is inflated.
Dust can be transferred easily and hygienically,
Furthermore, since the dust collection bag of the vacuum cleaner is pressed against the lid by a presser plate, this prevents the dust collection bag from coming into close contact with the filter due to negative pressure, impairing the dust collection action, and causing the electric blower to overheat. It is configured as follows.

An embodiment of this invention will be described based on the drawings.

A main body case 1 in which an electric blower 2 is built-in and a dust case 3 are provided.

This dust case 3 is formed with a dust collection chamber 5 that is open at the bottom and communicates with the suction port 4, and one end of a lid 6 for opening and closing the dust collection chamber 5 is rotatably connected by a hinge 7. .

The other end of the lid 6 is locked by a clamp mechanism 9 provided on a support wall 8 on the exhaust side of the dust case 3.

Then, the locking protrusion 10 formed on the other end of the lid 6 is locked in the locking recess 11 formed in the main body case 1, and the clamp 12 provided on the upper part of the dust case 3 is clamped to the main body case 1. As a result, the dust case 3 is detachably held in the main body case 1.

Next, a compression plate 14 connected to the operation button 13 is provided on the dust case 3 so as to be biased upward and movable up and down.

A filter frame 15 is housed in the dust collection chamber 5, and a coarse mesh primary filter 16 is detachably attached to the suction side end face of the filter frame 15.

A secondary filter 1 such as a sponge is placed inside the filter frame 15.
7 and a tertiary filter 18 which is bent in the shape of a dense paper bellows with a menosh is held.

Furthermore, a dust removal body 19 is rotatably attached to the support wall 8 to scrape off dust adhering to the tertiary filter 18.

Next, a dust collection bag 20 made of polyethylene or the like is placed in the dust collection chamber 5.
is stored.

The opening edge of the dust collection bag 20 is detachably held by an annular frame 21 which is a holder elastically joined to the peripheral wall of the dust collection chamber 5.

Thus, hinge pieces 22 are formed on both sides of the lower part of the -order filter 16, and a presser plate 2 is attached to these hinge pieces 22.
3 is attached so as to be able to move up and down while being biased downward by a spring 24.

Therefore, a part of the dust collection bag 20 is pressed against the lid 6 by the press plate 23, and another part is pressed against the lid 6 by the filter frame 15.

In such a configuration, dust is sucked into the dust collection chamber 5 through the suction port 4 by driving the electric blower 2 .

At this time, since the dust bag 20 is held down by the holding plate 23 and the filter frame 15, it is not sucked up by negative pressure and does not come into close contact with the primary filter 16.

Thereby, it is possible to prevent an accident in which the dust collection function is impaired or the electric blower 2 overheats.

Dust disposal is performed by operating the clamp 12 to remove the dust case 3 from the main case 1, and then removing the clamp mechanism 9.

That is, the lid 6 rotates downward about the hinge 7 as shown in FIG. 3, and the holding plate 23 pushes the dust collection bag 20 downward into the dust case 3 while expanding its volume.

Therefore, the dust in the dust case 3 is quickly transferred to the dust collecting bag 20 which is inflated by the holding plate 23.

Next, the dust collection bag 20 is sealed with a string or tape, and then removed from the dust case 3 together with the annular frame 21, and finally the annular frame 21 is removed.

Alternatively, the dust collection bag 20 is pulled and removed, leaving the annular frame 21 in the dust case 3.

Next, the unused dust collection bag 20 is set in the dust case 3 using the annular frame 21 for the next dust disposal, but unlike the case where the dust collection bag 20 is set each time the dust collection is done, the dust collection bag 20 in the dust case 3 is Because it is set with all dust removed,
No dust is scattered.

This makes it possible to dispose of dust easily and hygienically.

Note that although the annular frame 21 that is detachably attached to the dust case 3 is used as a holder, a member that detachably holds the opening edge of the dust collection bag 20 is fixedly provided on the dust case 3, and this member is used as a holder. You can also use it as

Further, although the holding plate 23 is attached to the primary filter 16, it may also be attached to the peripheral surface of the dust case 3.

Since this invention is configured as described above, by storing the dust collection bag in the dust collection chamber, it is possible to eliminate the trouble of searching for and attaching the dust collection bag when disposing of dust, and also to remove the lid. When opened, the dust collection bag is already set, so the dust inside the dust case does not scatter, and the holding plate expands the volume of the dust collection bag, making it easier to transfer dust to the dust collection bag. It can be done easily and hygienically, and since the dust collection bag is pressed against the lid by the press plate during cleaning, the dust collection bag does not come into close contact with the filter due to negative pressure, which improves the dust collection effect. This has the effect of being able to prevent accidents such as a decrease in air flow rate and overheating of the electric blower.
