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 diagonally lower side is described as the front, and the right diagonally upper side is defined as the rear. 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 detachably accommodated in the dust collection chamber 7. ing. 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. Here, the dust collecting container 10 shown in FIG. 2 to FIG. 4 and FIG. 5 to FIG. 7 to be described later is only for the purpose of explaining the outline, and in detail, the dust collecting container 10 of the present invention is Is different.

3 and 4, the dust collecting container 10 includes an outer case 11 (case), 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. In a state where the dust collecting container 10 is accommodated in the dust collecting chamber 7 of the vacuum cleaner main body 1, the air inlet 14 communicates with the suction hose mounting hole 3 formed in the main body 1 (see FIG. 2). Therefore, air and dust sucked in by a suction hose (not shown) are taken into the outer case 11 from the suction port 14. The back side which is the other side of the outer case 11 is open.

  The inner case 12 is formed of, for example, 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 (see FIG. 4). 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 applies centrifugal force to the dust in the air. The swirl flow path 25 for performing the above operation, the bypass flow path 30 for ensuring the flow of air entering from the air inlet 14, the dust collection space 26 for collecting dust, and the dust collection surface 27 described later are formed. The swirl flow path 25, the bypass flow path 30, the dust collection space 26, and the dust collection surface 27 are shown in FIG.

Thus, in the dust collection container 10, since the turning flow path 25 is formed by the outer case 11 and the inner case 12, dust collection can be performed by a so-called cyclone method. Further, since the dust collecting container 10 is provided with the bypass flow path 30, even if the swirl flow path 25 is clogged, the air flow from the intake port 14 to the filter device 13 can be secured.
More specifically, as shown in FIG. 4, in the front of the inner case 12, a buffer space 15 that receives air entering from the intake port 14, and a swirl flow path that guides the air in the buffer space 15 in a clockwise direction as shown in FIG. The formation part 16 and the semi-columnar convex part 17 which protruded inside toward the inside of the turning flow path formation part 16 are included. A large number of small vent holes 18 are formed on the peripheral surface of the convex portion 17 on the downstream side in the turning direction. Air and dust that have entered the buffer space 15 from the air inlet 14 mainly flow along the swirl flow path forming portion 16 while rotating clockwise as viewed from the front. That is, air and dust turn around the convex portion 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 convex portion 17 form a bypass flow path 30 for securing a flow of air entering from the intake port 14.

  The lower end portion of the filter device 13 is connected to the lower portion of the outer case 11 via a hinge 21. The inner case 12 is fitted to the outer case 11, the filter device 13 is rotated around the hinge 21 with respect to the outer case 11, and is closed so as to face the back side of the outer case 11. 13 is attached to the outer case 11, and the dust container 10 is comprised as shown in FIG.

  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 in a closed state in conjunction with the push button 22 are provided. Further, the filter device 13 is provided with a hook receiver 51. The hook receiver 51 is formed with a locking hole 52 penetrating in the front-rear direction. The hook 23 is inserted into the locking hole 52 and then engaged with the hook receiver 51, whereby the filter device 13 is inserted. The closed state is maintained. By operating the push button 22, the engagement state between the hook 23 and the hook receiver 51 can be released, and the filter device 13 can be opened (removed) from the outer case 11.

FIG. 5 is a diagram for explaining the flow of air flowing through the swirl passage 25 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. It is the perspective view which showed the dust container 10 from the front diagonally forward in the state.
As indicated by the thick arrows 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 convex portion 17. First, it flows in the left direction and turns clockwise around the 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 where the filter device 13 is opened. .
Referring to FIG. 6, a swirl flow path 25 is formed by the outer case 11 and the inner case 12, and air and dust 20 flow along the swirl flow path 25 (see the thick arrow in the drawing). When viewed from the back side, the guide surface 24 that smoothly bulges in a convex curve forming the downstream inner portion of the swirl passage 25 is partitioned by the inner case 12. The guide surface 24 is the back side of the buffer space 15 (see FIGS. 4 and 5) formed by the inner case 12. The guide surface 24 smoothly guides the air and dust 20 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 20.

  A dust collection space 26 is defined around the downstream side of the swirl passage 25. Here, the inner surface of the outer case 11 and the back surface (back surface) of the inner case 12 that define the swirl passage 25 and the dust collection space 26 including the guide surface 24 are collectively referred to as a dust collection surface 27. That is, the dust collection surface 27 is formed by the outer case 11 and the inner case 12. The dust collection space 26 is partitioned by a dust collection surface 27 on the front side, and is partitioned by the filter device 13 in a closed state on the back side. Since the centrifugal force is applied to the dust 20 in the air while the air and the dust 20 pass through the swirl flow path 25, the dust 20 flows outside the swirl flow path 25, as schematically shown in FIG. Then, it accumulates from the outside of the dust collection space 26.

Even if a large amount of dust 20 accumulates in the dust collection space 26, the downstream side of the swirl passage 25 has the above-described smoothly swelled guide surface 24 by the inner case 12. The dust 20 hardly adheres to the air, and air can be swirled in the swirling flow path 25. (As shown by the broken arrows in the figure, the air turns.)
Therefore, even when a large amount of dust 20 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 the air and the dust 20 flow smoothly through the swirl passage 25 so that the dust 20 does not adhere to the guide surface 24 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 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 resistance to flowing air Can be reduced, and a dust collecting container with improved performance can be obtained.

Next, the filter device 13 will be described.
As shown in FIG. 4 and as described above, the filter device 13 is connected to the outer case 11 by the 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.
On the front side of the first filter frame 35, a fine rectangular mesh filter 37 is arranged. The mesh filter 37 has a flat surface facing the outer case 11 (referred to as an opposing surface), captures the dust 20 accumulated in the dust collection space 26, and the dust 20 is behind (in FIG. 6, the mesh filter 37). To move down). The large dust 20 is blocked by the mesh filter 37, and the fine dust 20 can pass through the mesh filter 37 and flow backward together with air. That is, the mesh filter 37 captures large dust 20 while allowing air flowing out from the back side of the outer case 11 to pass therethrough. The first filter frame 35 and the mesh filter 37 may be collectively referred to as a first filter. Further, the hinge 21 described above is attached to the first filter frame 35 in the filter device 13.

  The second filter frame 36 is provided with a pleated filter 34 for capturing fine dust. The pleated filter 34 is a filter having a mountain-valley shape in which the cross-sectional shape is alternately folded in the opposite direction. The pleated filter 34 captures fine dust 20 while allowing air flowing out from the back side of the outer case 11 to pass therethrough. The air that has passed through the pleat filter 34 is discharged to the outside through an electric blower (not shown). As described above, in the filter device 13, the relatively large dust 20 is captured by the mesh filter 37, and the relatively small dust 20 is captured by the pleated filter 34. Can be captured.

  In order to hold the pleat filter 34, the second filter frame 36 is provided with a holding member 38 for the pleat filter 34 as shown in FIG. The holding member 38 has irregularities that match the peak-and-valley shape of the pleated filter 34, and holds the end and center of the pleated filter 34. In addition, since it is complicated to illustrate the pleated filter 34 itself, the holding member 38 is shown in FIG. 4 and the pleated filter 34 itself is omitted. Note that the second filter frame 36 and the pleat filter 34 may be collectively referred to as a second filter. The second filter is disposed on the opposite side of the outer case 11 with respect to the first filter (the first filter frame 35 and the mesh filter 37), that is, at a position farthest away from the outer case 11 on the back side.

  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. 7 shows a state in which the tissue paper 40 is placed on the mesh filter 37 in FIG. As shown in FIG. 6, the mesh filter 37 is provided on the front side (the upper surface side in FIG. 6) of the filter device 13 as described above, and the captured dust 20 is outside the mesh filter 37. It is captured on the surface facing the case 11 and stored in the dust collection space 26.

  Here, when discarding the dust 20 accumulated in the dust collection container 10, the filter device 13 is opened with respect to the outer case 11, and the dust 20 accumulated on the opposing surface of the dust collection space 26 and the mesh filter 37 is discarded. In this case, fine dust 20 may adhere to the opposing surface of the mesh filter 37, the mesh filter 37 may be clogged, or the dust 20 attached to the mesh filter 37 may be difficult to throw away.

  Therefore, in this embodiment, as shown in FIG. 7, the tissue paper 40 is placed on the mesh filter 37, and the captured dust 20 is accumulated on the tissue paper 40, so that the filter device 13 is against the outer case 11. When the is opened, the captured dust 20 is easily discarded. That is, in the state shown in FIG. 7, when the filter device 13 and the outer case 11 are closed together after the tissue paper 40 is placed on the mesh filter 37, the tissue paper 40 is sandwiched between the filter device 13 and the outer case 11, Can be installed between these. Thereby, since the dust 20 can be captured with the tissue paper 40 prior to the filter device 13, the life of the filter device 13 can be extended. Further, when the tissue paper 40 is soiled with the dust 20, it is only necessary to replace the tissue paper 40 with a new tissue paper 40, so that maintenance is easy.

  Here, as described above, in the mesh filter 37, the facing surface that captures the dust 20 is flat (see FIG. 6). Therefore, when the filter device 13 is opened with respect to the outer case 11, the facing surface of the mesh filter 37 is not only made to face upward, but if this is not horizontal, the tissue paper on the facing surface of the mesh filter 37. The dust 20 placed on 40 is spilled unexpectedly, causing a problem of soiling the floor (see FIG. 7). Note that. A similar problem occurs even when the tissue paper 40 is not used.

FIG. 8 shows a mode in which the present invention is applied in FIG. FIG. 9 shows a mode in which the present invention is applied in FIG. FIG. 10 is a diagram for explaining a state in which the tissue paper 40 and the dust 20 are discarded in FIG. 9.
In order to eliminate such a problem, the mesh filter 37 has a storage part 41 as shown in FIG. The storage part 41 is formed in three dimensions by a main surface 28 facing the outer case 11 and a side surface 29. Specifically, the main surface 28 is a substantially trapezoidal inclined surface connected to the peripheral edge of the first filter frame 35 on the hook receiver 51 side while being widened from the hinge 21 side to the hook receiver 51. The side surface 29 is an inclined surface that rises from the end of the main surface 28 (excluding the hook receiver 51 side) in the intersecting direction of the main surface 28 and is connected to the peripheral edge of the first filter frame 35 (excluding the hook receiver 51 side). . That is, the storage part 41 is wide and shallow from the hinge 21 side toward the opposite side of the hinge 21 side (the hook receiver 51 side) with respect to the storage part 41, and has a dish shape with a bottom. It is formed in a dust removal shape whose side is the gripping portion side.

  Therefore, when the tissue paper 40 is placed on the mesh filter 37, the tissue paper 40 is deformed along the shape of the storage part 41 of the mesh filter 37 as shown in FIG. Become a shape. As a result, when the filter device 13 is opened with respect to the outer case 11, the dust 20 placed on the tissue paper 40 spills from or rises up around the tissue paper 40 without leveling the storage portion 41. The dust 20 and the tissue paper 40 can be thrown away smoothly from the hook receiver 51 side in the storage part 41.

  Then, as shown in FIG. 10, when the outer case 11 and the filter device 13 are opened from each other, the handle 19 is grasped and the entire dust collection container 10 is tilted so that the hook receiver 51 side faces downward. The dust 20 on the paper 40 and the tissue paper 40 is shifted downward so as to be separated from the hinge 21 side (see the thick arrow in the figure). If a trash box (not shown) is disposed at the tip of the slip, the dust 20 can be thrown into the trash box without spilling on the floor surface.

Further, referring to FIG. 8, the back shapes of outer case 11 and inner case 12 are different from those shown in FIG.
Specifically, a rib protruding to the mesh filter 37 side (referred to as a compression chamber partitioning rib 42) on the side near the guide surface 24 of the inner case 12, that is, on the left side in FIG. Are provided integrally.

Further, a curved surface (substantially C-shaped in a rear view) that divides the dust collection surface 27 along the convex portion 17 described above (a dust collection surface partition rib 43) is provided at a substantially upper right portion on the back side of the inner case 12. Are provided integrally. The dust collection surface partition ribs 43 partition the upper right side in FIG. 8 of the dust collection surface 27 and protrude toward the mesh filter 37 side.
Further, a rib (referred to as a bypass passage partition rib 44) that is continuous with the dust collection surface partition rib 43 and protrudes toward the mesh filter 37 is integrally provided on the right side portion in FIG. 8 of the dust collection surface 27. It has been. The bypass channel partition rib 44 has a substantially inverted L shape when viewed from the back, and defines the lower side of the bypass channel 30 in FIG. Note that the dust collecting surface partition rib 43 and the bypass channel partition rib 44 that are continuous with each other partition the bypass channel 30, the swirl channel 25, and the dust collection space 26.

  A wall (referred to as a revolving wall 45) is provided inside the bypass channel 30, specifically, inside the convex portion 17 and extending in the reverse side in a reverse S-shape when viewed from the back. By providing the swirl wall 45, the bypass flow path 30 is provided with a swirl flow path (referred to as a swirl flow path 46 in the bypass (swivel part)) having a substantially C shape in the back view. As a result, the air flowing through the small vent hole 18 to the bypass flow path 30 inside the convex portion 17 is swung counterclockwise in the bypass swirl flow path 46 as viewed from the rear (the one-dot chain line in the drawing). See arrow). At this time, centrifugal force is applied to the dust 20 in the air. Thereby, the dust 20 can be separated from the air passing through the bypass flow path 30. Here, at the right end in FIG. 8, the swivel wall 45 extends linearly toward the hook 23 along the air flow direction in the bypass flow path 30.

  These compression chamber partition ribs 42, dust collection surface partition ribs 43, bypass flow path partition ribs 44 and swivel walls 45 protrude from the rear surface side periphery of the outer case 11 to the back surface side, that is, the mesh filter 37 side ( Each protruding portion is stored in the storage portion 41 of the mesh filter 37 when the outer case 11 and the filter device 13 are closed to each other. In particular, it can be said that the dust collection surface partition rib 43, the bypass channel partition rib 44 and the swivel wall 45 are components on the inner case 12 side, and the inner case 12 protrudes from the outer case 11. However, since the portion that protrudes from the inner case 12 is stored in the storage portion 41 in this way, the dust collecting container 10 does not increase by the amount that the inner case 12 protrudes from the outer case 11, and the dust collecting container 10 can be prevented from being increased in size. In addition, when the outer case 11 and the filter device 13 are closed to each other, the dust collection surface 27 and the storage portion 41 face each other.

  When the outer case 11 and the filter device 13 are closed after the tissue paper 40 is placed on the mesh filter 37, the compression chamber partition rib 42, the dust collecting surface partition rib 43, and the bypass flow path partition rib shown in FIG. 44 presses the tissue paper 40 against the filter device 13 so as to follow the dust removal shape of the storage portion 41 of the mesh filter 37. As a result, the tissue paper 40 is positioned between the filter device 13 and the outer case 11 and has a dust removal shape substantially equal to the shape of the storage portion 41.

  At the same time when the tissue paper 40 is positioned, the first compression chamber 47 (compression chamber 47) (the compression chamber 47) is interposed between the compression chamber partition rib 42 and the left side surface 29, main surface 28, and dust collection surface 27 in FIG. ) Is formed. That is, the compression chamber partition rib 42 partitions the first compression chamber 47. Further, a second compression chamber 48 (compression chamber) is formed between the dust collection surface partition rib 43, the bypass flow channel partition rib 44, the main surface 28, and the dust collection surface 27. In addition, a third compression chamber 49 (compression chamber) is formed between the portion of the revolving wall 45 extending toward the hook 23 as described above and the right side surface 29 in FIG. For convenience of explanation, the first compression chamber 47, the second compression chamber 48, and the third compression chamber 49 are shown on the back side of the outer case 11 and the inner case 12. Here, it can be said that the first compression chamber 47 and the second compression chamber 48 are provided in the dust collection surface 27, and the third compression chamber 49 is provided in the bypass flow path 30. The first compression chamber 47, the second compression chamber 48, and the third compression chamber 49 are provided on the peripheral side of the storage portion 41, and are out of the center of the storage portion 41 (specifically, the center of the main surface 28). In the position.

  In this way, the compression chamber partition rib 42 can position the tissue paper 40 in addition to partitioning the first compression chamber 47. Further, the dust collection surface partition ribs 43 can position the tissue paper 40 in addition to partitioning the dust collection surface 27. In addition to partitioning the bypass channel 30, the bypass channel partition rib 44 can also position the tissue paper 40. Therefore, it is not necessary to separately provide a part for positioning the tissue paper 40, and the dust collecting container 10 can be simply configured.

  When the filter device 13 is attached (closed) to the outer case 11, the tissue paper 40 can be positioned together, so that the tissue paper 40 can be easily attached. In order to prevent the tissue paper 40 placed on the mesh filter 37 from moving, it is preferable that the filter device 13 is stationary and the outer case 11 is closed with respect to the filter device 13.

Furthermore, the compression chamber partition rib 42, the dust collection surface partition rib 43, and the bypass flow path partition rib 44 press the tissue paper 40 against the filter device 13 so as to follow the shape of the storage portion 41. Can be installed without breaking.
As described above, the dust collection surface 27 faces the storage portion 41 that stores the dust 20, and the dust 20 to which the centrifugal force is applied in the swirling flow path 25 is divided into the dust collection surface 27, the storage portion 41, and the like. (A part of the dust collection space 26) and a part of them is taken into the first compression chamber 47. The dust 20 is subsequently compressed by the dust 20 taken into the first compression chamber 47 (see the solid line arrow in the figure). When the dust 20 is taken up to the full in the first compression chamber 47, the dust 20 flowing along the swirl passage 25 is now taken into the second compression chamber 48 and is the same as in the first compression chamber 47. (See the broken arrow in the figure). Thus, since the first compression chamber 47 and the second compression chamber 48 are provided on the dust collection surface 27, it is possible to prevent the dust 20 from being clogged at an early stage between the dust collection surface 27 and the storage portion 41. Thereby, the dust collection capability of the dust collection container 10 can be improved.

  Further, as described above, the dust 20 flowing in the convex portion 17, that is, in the bypass flow path 30, is swung counterclockwise in the rear view while being applied with centrifugal force. It flows outside and is taken into the third compression chamber 49 and compressed in the same manner as in the first compression chamber 47 and the second compression chamber 48 (see the dashed line arrows in the figure). Thus, since the third compression chamber 49 is provided in the bypass flow path 30, the dust 20 separated from the air can be compressed by the swirl flow path 46 in the bypass, and the bypass flow path 30 is compressed by the dust 20. It can prevent clogging early. Thereby, the dust collection capability of the dust collection container 10 can be improved.

  Further, as described above, the first compression chamber 47, the second compression chamber 48, and the third compression chamber 49 are arranged at positions that are out of the center of the storage portion 41. Here, the center of the storage part 41 is a position where the suction force tends to concentrate when the vacuum cleaner main body 1 is operated, and the first compression chamber 47, the second compression chamber 48, and the third compression chamber 49 that take in the dust 20 are arranged. By removing from the center of the storage unit 41, it is possible to suppress a decrease in suction force.

FIG. 11 is a side view of the dust collecting container 10 in a state where the outer case 11 and the filter device 13 are closed. FIG. 12 is a side view of the dust collecting container 10 in a state where the outer case 11 and the filter device 13 are opened from each other and placed on the floor surface. FIG. 13 shows a state in which the dust collecting container 10 is suspended in the air by grasping the handle 19 in FIG.
As shown in FIG. 11, the rear side periphery (the right side periphery in FIG. 11) of the outer case 11 and the periphery (the left side periphery in FIG. 11) of the storage portion 41 of the mesh filter 37 facing the outer case 11 The filter device 13 is formed so as to be inclined with respect to the passage direction X of the air flowing out from the back side of the outer case 11 when the filter device 13 is closed. Thereby, compared with the case where the periphery of the storage part 41 is orthogonal to the passage direction X of air, in the storage part 41, more air flowing out from the outer case 11 can be passed, and the storage part 41 is formed. The main surface 28 and the side surface 29 can be enlarged. Therefore, the storage part 41 can be prevented from being clogged with the dust 20 at an early stage. Thereby, the dust collection capability of the dust collection container 10 can be improved. In addition, by increasing the main surface 28 and the side surface 29, the amount of dust 20 captured by the mesh filter 37 can be increased.

  Further, as shown in FIG. 12, the back side peripheral edge (upper peripheral edge in FIG. 12) of the outer case 11 and the peripheral edge (upper peripheral edge in FIG. 12) of the storage portion 41 are opened from the outer case 11 and the filter device 13. When formed, it is formed so as to be substantially continuous in the horizontal direction. Therefore, the tissue paper 40 can be easily placed on the storage unit 41, and the tissue paper 40 can be prevented from spilling from the storage unit 41.

  Further, as shown in FIG. 13, the pleat filter 34 and the second filter frame 36 are centered on a shaft 57 at a position different from the rotation shaft (the shaft of the hinge 21) of the first filter frame 35 with respect to the outer case 11. The first filter frame 35 is rotatably connected. Here, when the handle 19 is grasped and the outer case 11 and the filter device 13 are opened with the dust container 10 suspended in the air, the second filter frame 36 rotates downward with respect to the first filter frame 35. Then, the space between the first filter frame 35 and the second filter frame 36 is opened. Thereby, the pleated filter 34 described above is exposed from between the first filter frame 35 and the second filter frame 36, and can be taken out.

  As described above, since the rotation shaft 57 of the second filter frame 36 and the rotation shaft of the first filter frame 35 (the shaft of the hinge 21) are located at different positions, the first filter is compared with the case where they are the same. The second filter frame 36 and the pleat filter 34 are easily rotated (easy to open) with respect to the frame 35. Therefore, the dust 20 captured by the pleated filter 34 can be thrown away smoothly. As a result, the dust collection container 10 can be easily handled.

FIG. 14 is a side sectional view of the dust collecting container 10 in a state where the outer case 11 and the filter device 13 are closed with the tissue paper 40 interposed therebetween.
As described above, the filter device 13 (specifically, the second filter frame 36) is provided with the hook receiver 51, and the hook receiver 51 is formed with the locking hole 52 (see FIG. 8).

  When the hook 23 provided in the outer case 11 is engaged with the hook receiver 51, the tip of the hook 23 (the right side in FIG. 14) enters the locking hole 52 as shown in FIG. 14. At this time, a portion of the tissue paper 40 positioned in the locking hole 52 is sandwiched between the hook 23 and the hook receiver 51. This makes it difficult for the hook 23 to be engaged with the hook receiver 51, and conversely, the engagement state between the hook 23 and the hook receiver 51 is difficult to be released. There is a risk of tearing at a portion sandwiched between the hook receiver 51. If the tissue paper 40 is made small as a whole so as not to be pinched between the hook 23 and the hook receiver 51, the so-called pinching margin is reduced as a whole, so that the space between the outer case 11 and the filter device 13 is reduced. It becomes difficult to sandwich the tissue paper 40.

15 is a plan view of the disposable sheet 53 according to the present invention, and FIG. 16 is a diagram in which the disposable sheet 53 is applied in FIG. FIG. 17 is a modification of FIG. 15 applied.
In order to eliminate the above-described problems, the disposable sheet 53 shown in FIGS. 15 and 16 is applied.

  Specifically, in the disposable sheet 53, when the disposable sheet 53 is placed on the mesh filter 37, a portion close to the hook receiver 51 is cut away. That is, the disposable sheet 53 is formed with a V-shaped notch 58 as shown in FIG. Accordingly, as shown in FIG. 16, the disposable sheet 53 can be placed on the mesh filter 37 by avoiding the hook receiver 51 at the notch 58. Therefore, when the outer case 11 and the filter device 13 are closed to each other, the disposable sheet 53 is not sandwiched between the hook 23 and the hook receiver 51, and the above-described problems can be solved. Further, in the disposable sheet 53, it is possible to secure a pinch margin necessary for being pinched between the outer case 11 and the filter device 13 at a portion other than the notch 58.

As a modification of the disposable sheet 53, the notch 58 may be semicircular as shown in FIG.
FIG. 18 is a plan view of the scooping frame 54 attached to the dust collecting container 10. FIG. 19 is a side sectional view of the dust collecting container 10 when the filter device 13 is opened with respect to the outer case 11 and the dust 20 is discarded. FIG. 20 is a diagram in which the net 56 is applied in FIG.

When the dust 20 in the dust collecting container 10 is thrown away, the scooping frame 54 shown in FIG.
The scooping frame 54 has a substantially rectangular frame shape that approximates the periphery of the mesh filter 37, and is supported by the hinge 21 (see FIG. 19). The scooping frame 54 is sandwiched between the outer case 11 and the periphery of the mesh filter 37 when the outer case 11 and the filter device 13 are closed to each other. Here, when the outer case 11 and the filter device 13 are closed to each other, the tissue paper 40 is sandwiched between the scooping frame 54 and the outer case 11. Then, as shown in FIG. 19, when the filter device 13 is opened with respect to the outer case 11 and rotated downward, the scooping frame 54 takes a substantially horizontal posture and is not shown. The tissue paper 40 is placed on the frame 54. However, since the scooping frame 54 has a substantially rectangular frame shape as described above, the inside is a space. Therefore, the dust 20 on the tissue paper 40 is biased and collected on the inner side of the scooping frame 54 in the tissue paper 40, so that the tissue paper 40 is deformed into a bag shape and falls from the inside of the scooping frame 54 to the trash box 55. . Here, when the tissue paper 40 changes into a bag shape, the dust 20 is wrapped in the tissue paper 40 and hardly rises from the tissue paper 40.

  Further, as shown in FIG. 20, a net 56 may be stretched inside the scooping frame 54. The net 56 has elasticity and has a hole at the center. Therefore, the tissue paper 40 on which the dust 20 is placed is surely deformed into a bag shape when passing through the hole of the net 56 and falls into the trash box 55. Thereby, the rising of the dust 20 from the tissue paper 40 can be sufficiently prevented.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.
