Description

  The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner that can be attached with a garbage bag and can collect dust in the garbage bag.

Various types of conventional vacuum cleaners have been proposed that use a garbage bag generally called a paper pack as a container for storing sucked dust.
For example, Patent Document 1 proposes a vacuum cleaner having a paper pack and a detachable basket for mounting the paper pack.
Patent Document 2 proposes a vacuum cleaner that can be fitted with a simple dust box when the paper pack is exhausted.

Patent Document 3 proposes an electric vacuum cleaner that can be equipped with a paper pack or a cyclone dust collection type dust container instead of the paper pack.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic longitudinal sectional side view for explaining the structure of a vacuum cleaner 1 according to an embodiment of the present invention.
With reference to FIG. 1, the vacuum cleaner 1 is provided with the main body casing 2 formed, for example with resin. For example, on the rear side in the main casing 2, an electric blower housing chamber 3 is defined, and the electric blower 4 is housed in the housing chamber 3. A dust collection chamber 5 is defined on the front side of the electric blower housing chamber 3. The dust collection chamber 5 has an open top surface, and the open top surface is closed with a dust collection chamber cover 6 so that it can be opened and closed. FIG. 1 shows a state in which the dust collection chamber 5 is closed with the dust collection chamber cover 6, that is, a state in which the dust collection chamber cover is closed. On the other hand, FIG. 2 shows a state in which the dust collection chamber cover 6 is opened.

  Referring to FIGS. 1 and 2, dust collection chamber cover 6 is attached to main body casing 2 so as to be rotatable about support shaft 7. And in FIG. 1 and FIG. 2, the open surface which is the upper surface of the dust collection chamber 5 can be closed by rotating the dust collection chamber cover 6 counterclockwise centering on the spindle 7, conversely, The upper surface of the dust collection chamber 5 can be opened by rotating it about 90 degrees from the closed state about the support shaft 7 in the clockwise direction.

  The dust collection chamber cover 6 is formed with, for example, a suction port 8 penetrating the dust collection chamber cover 6 at a substantially central portion thereof. A rear end 10, which is one end of the suction pipe 9, can be inserted into the suction port 8. One end of a suction hose 11 shown only in part is connected to the distal end side which is the other end of the suction pipe 9. The suction pipe 9 is provided with a connection structure 12 for fitting with the dust collecting chamber cover 6 and holding the state where the suction pipe 9 is inserted when one end 10 is inserted into the suction port 8. A corresponding connected structure 13 is formed on the dust collection chamber cover 6 side.

  When the electric blower 4 is driven, dust is sucked together with air from a suction tool (not shown), and the air and dust enter the dust collection chamber 5 through the suction hose 11 and the suction pipe 9. Dust is captured. Then, the air passes around the electric blower 4 and is discharged to the outside of the main casing 2 from the exhaust port 14 formed on the rear surface side of the main casing 2.

Thus, air and dust flow into the dust collection chamber 5 through the suction hose 11 and the suction pipe 9. In order to capture the inflowing dust, a dust case 15 is accommodated in the dust collecting chamber 5 as a dust capturing member, and a dust bag 30 can be disposed in the dust case 15.
The dust case 15 is, for example, a box shape such as a substantially cubic shape or a substantially rectangular parallelepiped shape whose upper surface is open, and the four side surfaces and the bottom surface are, for example, mesh walls and have air permeability. And the part including each corner | angular part of the box shape is made into the frame structure so that it may have the rigidity which keeps a box shape.

The dust case 15 may be configured so that the air flowing in from the opened upper surface can flow out from any side surface or bottom surface to the electric blower housing chamber 3 side, and at least only a predetermined surface has air permeability.
The entire dust case 15 can be washed with water. Such a dust case can be integrally formed of, for example, a resin, or can be formed of a wire mesh and a metal frame. The dust case 15 itself constitutes a dust capturing filter capable of capturing dust.

As shown in FIG. 2, the dust case 15 can be taken into and out of the dust collection chamber 5 with the dust collection chamber cover 6 opened. When the dust case 15 is accommodated in the dust collection chamber 5, the open surface peripheral edge 17 of the accommodated dust case 15 has the same height as the open surface peripheral edge 16 that is the upper surface of the dust collection chamber 5. It is comprised so that it may become one.
The upper surface, which is the open surface of the dust collection chamber 5, can be closed with the inner cover 18. Referring to an enlarged view of portion A in FIG. 1, a seal packing 19 as a peripheral portion sealing means is fitted to the peripheral edge of the inner cover 18. The seal packing 19 is made of, for example, rubber, and has two fins 20 and 21 that extend left and right on the lower surface side of the inner cover 18. The outer fin 20 is in contact with the open surface peripheral edge 16 of the dust collecting chamber 5 and seals the open surface peripheral edge 16. Further, the inner fin 21 is in contact with the open surface periphery 17 of the dust case 15 and seals the open surface periphery 17 of the dust case 15.

That is, the seal packing 19 as the peripheral portion sealing means can contact both the open surface peripheral edge 16 of the dust collection chamber 5 and the open surface peripheral edge 17 of the dust case 15, and the open surface peripheral edge 16 of the dust collection chamber 5 and the dust. Both the open surface peripheral edge 17 of the case 15 and the dust collection chamber cover 6 can be hermetically sealed.
When the dust collection chamber cover 6 is closed, the seal packing 19 fitted to the peripheral edge of the inner cover 18 is pressed by the rib 22 provided on the inner surface side of the dust collection chamber cover 6, and the open surface peripheral edge 16 is outside. The fin 20 is securely sealed, and similarly, the open face periphery 17 is reliably sealed with the inner fin 21.

  The inner cover 18 is provided with a mounting mechanism 23 for setting the garbage bag 30 on the lower surface thereof, that is, on the surface facing the inside of the dust case 15. More specifically, the garbage bag 30 is, for example, a paper pack, and includes a cover 31 for mounting and a paper bag 32. An entrance 33 is formed at the center of the cover 31, and the entrance 33 is attached to the inner cover 18 so as to correspond to the suction port 8.

  As shown in the enlarged view of portion B in FIG. 1, the inner cover 18 is formed with a hole 24 into which the one end 10 of the suction pipe can be inserted at a substantially central portion thereof. For example, a seal packing 25 integrally formed of rubber is fitted. The seal packing 25 is provided with a fin 26 and a flange 27 for sealing a gap between the base 31 and the inner cover 18, and a seal between the outer peripheral surface of the one end 10 of the suction pipe 9 and the hole 24 of the inner cover 18. And a closing piece 29 for closing the hole 24 formed in the inner case 18 when the one end 10 of the suction pipe 9 is extracted.

The seal packing 25 hermetically seals between the hole 24 formed in the substantially central portion of the inner cover 18 and the one end 10 of the suction pipe 9 and between the inner cover 18 and the cover 31. Therefore, there is no possibility that air and dust flowing into the dust collection chamber 5 through the suction pipe 9 will leak out of the machine from the hole 24 formed in the inner cover 18.
As described above, the seal packing 25 is integrally formed of rubber, for example, and can be easily manufactured and has high sealing performance.

  The upper surface which is an open surface of the dust collecting chamber 5 is covered with the inner cover 18 described above, and the inner cover 18 is provided with a seal packing 19 as a peripheral edge sealing means and a seal packing 25 as a central sealing means. Yes. For this reason, as shown in FIGS. 1 and 2, the electric vacuum cleaner 1 is used with a structure in which the dust case 15 is accommodated in the dust collecting chamber 5 and the dust bag 30 is disposed in the dust case 15. In addition, as shown in FIG. 3, it can be used without the garbage bag 30 attached, or as shown in FIG. 4, the dust case 15 is removed and only the garbage bag 30 is attached for use. It is also possible to do.

  In the use state shown in FIG. 3, the air and dust in the dust case 15 do not leak out from the peripheral edge 17 of the open surface. This is because the peripheral edge 17 of the open surface is hermetically closed by the seal packing 19. Further, since the hole 24 formed substantially at the center of the inner cover 18 and the one end 10 of the suction pipe 9 are airtightly closed by the projection 28 of the seal packing 25, the dust case passes through the hole 24. The air and dust in 15 do not leak out of the machine.

In the use state shown in FIG. 4, the dust case 15 is removed, but the open surface peripheral edge 16 of the dust collecting chamber 5 is airtightly closed by the fins 20 of the seal packing 19. Therefore, also in this case, the air in the dust collecting chamber 5 does not leak out from the peripheral edge 16 of the open surface.
FIG. 5 is a diagram showing a modification of dust case 15 and seal packing 19 in the configuration described in FIG.

  The feature of the configuration shown in FIG. 5 is that the open surface periphery 17 of the dust case 15 is configured to be one step higher than the open surface periphery 16 of the dust collecting chamber 5. When the open surface peripheral edge 17 of the dust case 15 is raised one step higher than the open surface peripheral edge 16 of the dust collection chamber 5 as shown in FIG. 5, the dust collection chamber cover 6 is opened, and the dust case 15 is removed from the dust collection chamber 5. When taking out, there exists an advantage that the dust case 15 is easy to take out.

In this case, the structure of the seal packing 19 is devised so that the seal packing 19 reliably and tightly closes both the open surface peripheral edge 16 of the dust collecting chamber 5 and the open surface peripheral edge 17 of the dust case 15. Yes.
Referring to the enlarged view of portion A in FIG. 5, the peripheral portion of the inner cover 18 is bent downward from the horizontal direction, and a seal packing 19 is fitted therein. The outer fin 20 and the inner fin 21 provided in the seal packing 19 can be brought into pressure contact with the open surface peripheral edge 16 of the dust collecting chamber 5 and the open surface peripheral edge 17 of the dust case 15, respectively.

By adopting such a configuration, even if there is a difference in height between the open surface peripheral edge 16 of the dust collecting chamber 5 and the open surface peripheral edge 17 of the dust case 15, the open surface peripheral edges 16, 17 are reliably sealed airtight. can do.
The rest of the configuration is the same as in FIG. 1, and the same parts are denoted by the same reference numerals, and redundant description is omitted.

FIG. 6 is a schematic longitudinal cross-sectional side view for explaining the configuration of a vacuum cleaner 60 according to another embodiment of the present invention. In the configuration shown in FIG. 6, the same components as those in FIG.
A feature of the electric vacuum cleaner 60 shown in FIG. 6 is that when the dust case 15 accommodated in the dust collecting chamber 5 is taken out, a lifting mechanism 61 is provided as an auxiliary means for taking out the dust case 15.

  The lifting mechanism 61 extends along the bottom surface of the dust collection chamber 5, a fork portion 62 positioned below the dust case 15 accommodated in the dust collection chamber 5, and an arm that is connected to the fork portion 62 and extends vertically upward. An inverted L-shaped member having a portion 63 and a long hole 64 provided in the dust collection chamber cover 6 for connecting the upper end of the arm portion 63 to the dust collection chamber cover 6 are included. The fork part 62 and the arm part 63 can be formed of, for example, a metal wire or a plastic material.

  In such a configuration, when the dust collection chamber cover 6 is opened from the state of FIG. 6 as shown in FIG. 7, the arm portion 63 is moved upward through the long hole 64 along with the operation of opening the dust collection chamber cover 6. The fork part 62 connected to the lower part of the arm part 63 lifts the dust case 15 upward. Thereby, when taking out the dust case 15 from the dust collection chamber 5, the easiness of taking it out improves markedly.

The structure of the lifting mechanism 61 is not limited to the structure shown in FIGS. 6 and 7, and at least the lifting member disposed on the inner bottom surface of the dust collecting chamber 5 and the space between the lifting member and the dust collecting chamber cover. Any structure may be used as long as the lifting member moves up and down in conjunction with opening and closing of the dust collection chamber cover 6.
