Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a vacuum cleaner body 1 according to an embodiment of the present invention. In the vacuum cleaner main body 1 shown in FIG. 1, the left oblique lower side is described as the front and the right oblique upper side is the rear, and in the following description, when specifying the direction, the front and rear, the left and right, the upper and lower Is identified.

  The outer shape of the main body 1 is defined by a housing 2 made of resin, for example, and a suction hose mounting hole 3 is formed on the front surface of the housing 2. Also, relatively large-diameter wheels 4 are provided on the left and right sides of the housing 2 near the rear. Furthermore, a handle 5 is provided on the upper surface of the housing 2 and can be raised from the folded state shown in the figure to a standing state. A cover 6 that can be opened and closed is disposed on the front side of the handle 5. The cover 6 has a fulcrum for opening and closing on the rear side, and the front side can be opened upward to expose the inside.

FIG. 2 is a perspective view of the electric vacuum cleaner body 1 with the cover 6 removed. A dust collection chamber 7 communicating with the suction hose mounting hole 3 is formed in the vacuum cleaner main body 1 covered with the cover 6, and a dust collection container 10 is accommodated in the dust collection chamber 7. An electric blower (not shown) is incorporated behind the dust collection chamber 7.
FIG. 3 is a perspective view of the dust collection container 10, and the lower left side in the drawing is the front surface of the dust collection container 10. FIG. 4 is an exploded perspective view of the dust collection container 10, and in FIG. 4, the right side is the front surface of the dust collection container 10. With reference to FIGS. 3 and 4, the dust collection container 10 includes an outer case 11, an inner case 12, and a filter device 13.

  The outer case 11 is formed of a transparent or translucent resin, and the inside can be seen through. An intake port 14 is formed on the front surface which is one surface of the outer case 11. As shown in FIG. 2, in a state where the dust collection container 10 is accommodated in the dust collection chamber 7 of the electric vacuum cleaner main body 1, the air inlet 14 communicates with the suction hose mounting hole 3 formed in the main body 1. Therefore, air and dust sucked in by the suction hose are taken into the outer case 11 from the air inlet 14. The back side which is the other side of the outer case 11 is open.

  The inner case 12 is formed of a resin colored in primary colors such as yellow, red, and blue, and is fitted into the outer case 11 from the back side of the outer case 11. Since the outer case 11 is transparent or semi-transparent in the fitted state, it can be confirmed through the outer case 11 that the inner case 12 is disposed therein. When the inner case 12 is fitted to the outer case 11, the inner case 12 cooperates with the outer case 11 to mainly pass air and dust entering from the air inlet 14 of the outer case 11, and centrifugal force is applied to the dust in the air. A swirl flow path for imparting air, a bypass flow path for securing a flow of air entering from the intake port 14, and a dust collection space for collecting dust are formed.

  Therefore, as shown in FIG. 4, the inner case 12 includes a buffer space 15 that receives air entering from the air inlet 14, a swirl flow path forming portion 16 that guides the air in the buffer space 15 clockwise, and a swirl flow A semi-columnar convex portion 17 protruding forward is included inside the path forming portion 16. A large number of small vent holes 18 are formed on the peripheral surface of the semi-columnar convex portion 17 on the downstream side in the turning direction. The air and dust that have entered the buffer space 15 from the intake port 14 flow to the downstream side while turning clockwise along the swirl flow path forming portion 16. That is, it turns around the convex part 17. At this time, since a large number of ventilation holes 18 are formed in the convex portion 17, a part of the swirling air flows to the back side through the ventilation holes 18. As described above, the large number of ventilation holes 18 formed in the semi-columnar protrusion 17 form a bypass flow path for ensuring the flow of air entering from the intake port 14.

As shown in FIG. 4, the filter device 13 is connected to the lower portion of the outer case 11 via a hinge 21. When the inner case 12 is fitted to the outer case 11 and the filter device 13 is rotated around the hinge 21 and closed so as to face the back side of the outer case 11, as shown in FIG. A dust container 10 is configured.
The outer case 11 is provided with a handle 19 on the upper surface side. Further, on the rear end side of the handle 19, a push button 22 and a hook (see FIG. 6) 23 for locking the filter device 13 interlocking with the push button 22 in a closed state are provided.

FIG. 5 is a diagram for explaining the flow of air flowing through the swirl flow path in the dust collecting container 10, with the outer case 11 and the inner case 12 separated and the filter device 13 removed from the outer case 11. FIG. 5 is a perspective view showing the dust collecting container 10 from a front oblique front.
As shown in FIG. 5, the air that has entered from the air inlet 14 of the outer case 11 accumulates in the buffer space 15 partitioned by the inner case 12, and rotates clockwise from the buffer space 15 around the semi-columnar convex portion 17. First, it flows in the left direction and turns clockwise around the semi-columnar convex portion 17.

FIG. 6 is a view for explaining the flow of air and dust in the dust collection container 10, and is a perspective view of the dust collection container 10 as viewed from the back side, and is a view in a state in which the filter device 13 is opened. is there.
With reference to FIG. 6, a swirl flow path 25 is formed by the outer case 11 and the inner case 12, and air and dust flow along the swirl flow path 25. When viewed from the back side, a guide surface 15A that bulges smoothly into a convex curve forming the downstream inner portion of the swirl passage 25 is partitioned by the inner case 12. The guide surface 15A is the back surface side of the buffer space 15 (see FIGS. 4 and 5) formed by the inner case 12. The guide surface 15A smoothly guides the air and dust flowing through the swirl flow path 25 on the downstream side of the swirl flow path 25, and assists the swirling of the air and dust.

As shown in FIG. 6, a dust collection space 26 is defined around the downstream side of the swirl passage 25. Since centrifugal force is applied to the dust in the air while air and dust pass through the swirl flow path 25, the dust D flows outside the swirl flow path 25, as schematically shown in FIG. In addition, it accumulates from the outside of the dust collection space 26.
And when many dusts D accumulate in the dust collection space 26, it will be in the state of FIG. As shown in FIG. 7, dust D accumulates from the outside of the dust collection space 26. However, the downstream side of the swirl passage 25 has the above-described smoothly swelled guide surface 15A by the inner case 12, and dust D hardly adheres to the guide surface 15A, and the dust collection space. Even in a state where a large amount of dust D is accumulated around 26, air can be swirled in the swirling flow path 25. (As shown by the thick arrows in FIG. 7, the air swirls.)
Therefore, even when a large amount of dust D is accumulated in the dust collection space 26, the air flow in the swirling flow path 25 itself is not hindered, the air swirls, and the suction force hardly decreases.

  The inner surface of the outer case 11 and the inner case 12 are arranged so that air and dust flow smoothly through the swirl passage 25, and the dust 26 does not adhere to the guide surface 15A and can be collected smoothly from around the dust collection space 26. For example, a fluorine resin such as Teflon (registered trademark) may be coated on the front and back surfaces of the film at the molecular level. Alternatively, carbon may be vapor-deposited on the inner surface of the outer case 11 and both the front and back surfaces of the inner case 12. By coating the fluorine resin at the molecular level or by depositing carbon, the water repellency of the inner surface of the outer case 11 and the front and back surfaces of the inner case 12 is improved, dust separation is improved, dirt is prevented, and the flowing air is prevented. Resistance can be reduced, and a dust collecting container with improved performance can be obtained.

FIG. 8 is a perspective view for explaining a locking structure when the inner case 12 is fitted to the outer case 11.
The back side of the outer case 11 is an open opening as described above, and the inner case 12 is fitted from the back side. A claw 31 is provided along one side of the outer case 11 (specifically, along the left side) so that when the inner case 12 is fitted in the outer case 11, the state is locked. Yes. Further, the inner case 12 has a recessed portion 32 formed along one side (specifically, along the left side) (see FIGS. 8A and 8B).

When the inner case 12 is fitted to the outer case 11, as shown in FIG. 8C, the claw 31 is fitted to the recessed portion 32, and the fitting state of the outer case 11 and the inner case 12 is locked.
The outer case 11 is formed with a gripping rib 33 protruding outward on the left side where the claw 31 is formed. The rib 33 is gripped when the inner case 12 is removed from the outer case 11. By gripping the rib 33, the claw 32 formed in the outer case 11 from the recessed portion 32 formed in the inner case 12. Can be easily removed.

Next, the filter device 13 will be described.
As shown in FIG. 4, the filter device 13 is connected to the outer case 11 by a pair of hinges 21. The filter device 13 includes filter frames 35 and 36 that form the outer periphery thereof, and two types of filters that are held by the filter frames 35 and 36.

  Specifically, referring to FIG. 6, the filter frame has a two-layer structure, and is connected to the first filter frame 35 connected to the outer peripheral edge of the back surface of the outer case 11 and the back surface of the first filter frame 35. And a second filter frame 36. A fine mesh filter 37 is arranged on the front side of the first filter frame 35. The mesh filter 37 prevents the dust D accumulated in the dust collection space 26 from moving backward. Large dust D is blocked by the mesh filter 37, and fine dust can pass through the mesh filter 37 and flow backward together with air.

  Therefore, the second filter frame 36 is provided with a pleated filter for capturing fine dust. The pleated filter is a filter having a mountain-valley shape in which cross-sectional shapes are alternately folded in opposite directions and are continuous. In order to hold the pleated filter, the second filter frame 36 is provided with a holding member 38 for the pleated filter, as shown in FIG. The holding member 38 has irregularities that match the ridges and valleys of the pleated filter, and holds the end and center of the pleated filter. Note that, since the pleat filter itself is complicated, the holding member 38 is shown in FIG. 4 and the pleat filter itself is omitted.

  The front side of the first filter frame 35 and the mesh filter 37 disposed there may be coated on the inner surface of the outer case 11 and the front and back surfaces of the inner case 12 described above. That is, the front side of the first filter frame 35 and the mesh filter 37 may be coated with a fluorine resin at a molecular level, or carbon may be evaporated. In this way, dust attached to the front side of the first filter frame 35 and the mesh filter 37 can be easily separated, and resistance to air passing through the mesh filter 37 can be reduced.

FIG. 9 is a rear view of the dust collecting container 10 and is a view for explaining a configuration of the filter device 13 viewed from the rear side.
On the back surface of the filter device 13, there is a second filter frame 36 that constitutes the outer periphery of the filter device 13. A region surrounded by the second filter frame 36 is a ventilation surface 39. Although not shown in FIG. 9, a pleated filter having peaks and valleys extending in the vertical direction is disposed on the ventilation surface 39. Further, a duster frame 40 extending in the left-right direction along the lower side 361 of the second filter frame 36 is attached. The duster frame 40 is provided with a dust removal lever 41 that is slidable in the left-right direction along the duster frame 40. The dust removal lever 41 is moved in the left-right direction along the duster frame 40, thereby flipping the pleat filter crease during the movement to vibrate the pleat filter and dropping the fine dust trapped in the pleat filter by the vibration. To prevent clogging of the pleated filter.

  As shown in FIG. 9, a plurality of through holes 401 are formed in the duster frame 40. When the duster frame 40 is attached along the lower side 361 of the second filter frame 36, the duster frame 40 and the dust removal lever 41 are connected to the ventilation surface. It is possible to reduce as much as possible the obstruction of the air flow at 39, and the suction power in the vacuum cleaner is not reduced. Further, the dust removing lever 41 is also formed with a plurality of through holes 411 so that the ventilation is not hindered. Further, since the duster frame 40 is attached along the lower side 361 of the second filter frame 36, there is an effect that the second filter frame 36 is reinforced.

  At the center of the upper side 362 of the second filter frame 36, a hook receiver 51 protruding upward is provided. The hook receiver 51 includes a locking hole 52 into which the hook 23 provided in the outer case 11 is fitted. Since the locking hole 52 of the hook receiver 51 is a through-hole at the front and rear, it is possible to prevent the sandwiched tissue paper from being broken by the engagement between the locking hole 52 and the hook 23 as will be described later.

Instead of the configuration of FIG. 9, a duster frame 40 may be attached along the upper side 362 of the second filter frame 36 as shown in FIG. 10. Even in such a configuration, the second filter frame 36 can be reinforced, and the duster frame 40 and the dust removal lever 40 can be prevented from interfering with the ventilation of the ventilation surface 39 to a minimum.
FIG. 11 is a perspective view of the main body 1 of the electric vacuum cleaner, with the cover removed and the dust collecting container 10 taken out from the dust collecting chamber 7.

The dust collection chamber 7 formed in the electric vacuum cleaner main body 1 can accommodate the dust collection container 10 described above, and can store a dust collection paper pack instead of the dust collection container 10. For this purpose, the rear surface 71 of the dust collection chamber 7 is provided with a rib 54 that extends in the vertical direction and protrudes into the dust collection chamber 7 at a predetermined interval.
As described above, an electric blower (not shown) is incorporated in the housing 2 of the vacuum cleaner body 1 behind the dust collection chamber 7. A ventilation hole 72 is secured on the rear surface 71 of the dust collection chamber 7. Therefore, the air in the dust collection chamber 7 is sucked to the rear surface 71 side. That is, the rear surface 71 functions as an inner surface for suction.

When the paper pack is accommodated in the dust collection chamber 7, the paper pack is flexible, so that it may be sucked by the rear surface 71 and block the ventilation hole 72 of the rear surface 71.
In order to prevent this, a rib 54 is provided on the rear surface 71 so that the paper pack does not adhere to the rear surface 74 by the rib 54 so that the ventilation holes 72 on the rear surface 74 are not blocked by the paper pack.

By the way, since the rib 54 is provided on the rear surface 71 of the dust collection chamber 7, when the dust collection container 10 is accommodated in the dust collection chamber 7, the dust removal lever 41 of the filter device 13 provided on the back surface of the dust collection container 10. May interfere with the ribs 54. In this embodiment, the following measures are taken so that the dust removal lever 41 does not interfere with the rib 54.
12A and 12B show the rear surface 71 of the dust collection chamber 7 and the position of the rib 54 provided on the rear surface 71, and the pleat filter 43 and the dust removal lever 41 when the dust collection container 10 is accommodated in the dust collection chamber 7. It is a top view showing the positional relationship of these.

  Referring to FIGS. 12A and 12B, the dust removal lever 41 protrudes backward (upward in FIGS. 12A and 12B) and forward (downward in FIGS. 12A and 12B) and is disposed in front of the handle. It has a claw 45 that collides with a peak of the pleated filter 43. When the dust collecting container 10 is taken out from the dust collecting chamber 7, when the handle 44 is pinched and the dust removing lever 41 is moved left and right along the duster frame 40, the claw 45 becomes a peak (crease peak) of the pleat filter 43. The pleat filter 43 is vibrated by hitting it and vibrating the pleat filter 43, and the fine dust accumulated in the pleat filter 43 is dropped to prevent clogging of the pleat filter 43.

  In the pleated filter 43, peaks and valleys are regularly folded at a constant pitch. On the other hand, since the claw 45 collides with the crease crest of the pleat filter 43 when the dust removal lever 41 is slid to the left and right along the duster frame 40, the stop position corresponds to the valley of the pleat filter 43. Always stop at the position. Therefore, the stop position of the handle 44 provided on the dust removal lever 41 is stopped at a pitch at a position where the claw 45 corresponds to the valley of the pleated filter 43.

  Therefore, in this embodiment, as shown in FIGS. 12A and 12B, the pitch between the valleys of the pleated filter 43 and the position of the rib 54 formed on the rear surface 71 are shifted. Therefore, the handle 44 stops at the position shown in FIG. 12A in accordance with the pitch of the valleys of the pleat filter 43, or stops at the position shown in FIG. The rib 54 is provided at a position where it does not interfere with the stopped handle 44 so as to deviate from the stop position of the handle 44.

  Returning to FIG. 11, the capacity of the dust collection chamber 7 of the vacuum cleaner body 1 is limited. That is, the vacuum cleaner body 1 is partitioned by the housing 2, and an electric blower, a control circuit, an electric wire cord, and the like are accommodated behind the housing 2, and the capacity of the dust collection chamber 7 is limited. . When the dust collecting chamber 10 having a capacity as large as possible is accommodated in the dust collecting chamber 7 having a limited capacity, if the rib 54 is protruded from the rear surface 71 of the dust collecting chamber 7, the rib 54 54 and the protrusion of the dust collecting container 10 interfere with each other.

In this embodiment, as described above, the protrusion position of the rib 54 is designed in consideration of the stop position of the dust removal lever 41, so that interference between the handle 44 of the dust removal lever 41 and the rib 54 does not occur. As a result, it is realized that the high-performance dust collection container 10 is accommodated in the dust collection chamber 7 having a limited capacity.
FIG. 13 is a perspective view of a dust collection container 10 according to another embodiment of the present invention. The dust collecting container 10 shown in FIG. 13 is characterized in that a protrusion 61 for temporarily holding tissue paper or lifting it is provided in relation to the hinge 21. As described above, the mesh filter 37 is provided on the front surface of the filter device 3, and the captured dust is received by the mesh filter 37. When the dust collected in the dust collection container 10 is discarded, as shown in FIG. 13, the filter device 13 is opened from the outer case 11, and the dust accumulated on the dust collection space 26 and the mesh filter 37 is discarded. In this case, fine dust may adhere to the mesh filter 37, the mesh filter 37 may be clogged, or the dust attached to the mesh filter 37 may be difficult to throw away.

  Therefore, in this embodiment, when tissue paper is placed on the mesh filter 37 and the captured dust accumulates on the tissue paper and the filter device 13 is opened, the captured dust is easily discarded. Has been. That is, in the state shown in FIG. 13, a tissue paper is placed on the mesh filter 37 so that the tissue paper placed between the filter device 13 and the outer case 11 can be sandwiched.

At that time, the protruding piece 61 is provided so that the tissue paper placed on the mesh filter 37 does not fall carelessly. The protruding piece 61 presses the filter frame 36 before the outer case 11 is put on the filter device 13, so that the tissue paper placed on the mesh filter 37 can be temporarily fixed.
Alternatively, when a tissue paper is placed on the protruding piece 61, as shown in FIG. 14, when the outer case 11 and the filter device 13 are opened, the protruding piece 61 lifts one end of the tissue paper T, and the tissue paper T There is also an advantage that it is easy to process so as to enclose the dust D placed thereon.
