Therefore, the dust captured by the second filter can be smoothly discarded.

As a result, the dust collecting container can be easily handled.

EMBODIMENT OF THE INVENTION Hereinafter, with reference to drawings, specific embodiment of this invention is described.

1 is a perspective view of an electric sweeper main body 1 according to an embodiment of the present invention. In the electric sweeper main body 1 shown in FIG. 1, the left inclined downward side is described as the front and the right inclined upper side as the rear, and in the following description, the direction is specified as well. Specifies.

The main body 1 is partitioned by the housing | casing 2 shape | molded with resin, for example, and the suction hose mounting hole 3 is formed in the front surface of the housing | casing 2. Moreover, the wheel 4 of a comparatively large diameter is provided in the rear left and right both sides of the housing 2. In addition, the upper surface of the housing 2 is provided with a handle 5 that can stand in the standing state from the folded state shown. The cover 6 which can be opened and closed is disposed at the front side of the handle 5. The cover 6 has an opening and closing point at the rear side, and the front side can be opened upward to expose the inside thereof.

2 is a perspective view of a state in which the cover 6 is removed from the electric sweeper main body 1. In the electric cleaner main body 1 covered with the cover 6, a dust collecting chamber 7 connected to the suction hose mounting hole 3 is formed, and the dust collecting chamber 10 is detachably attached to the dust collecting chamber 7. It is accepted. An electric blower (not shown) is built in the rear of the dust collecting chamber 7.

FIG. 3 is a perspective view of the dust collecting container 10, and in the drawing, the lower left slope is the front surface of the dust collecting container 10. As shown in FIG. 4 is an exploded perspective view of the dust collecting container 10, and in FIG. 4, the right side is the front surface of the dust collecting container 10. Here, the dust collection container 10 shown in FIGS. 2-4 and FIGS. 5-7 mentioned later is for the purpose of demonstrating the outline to the last, and is different from the dust collection container 10 of this invention in detail.

3 and 4, the dust collecting container 10 has 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 can penetrate the inside thereof. An inlet 14 is formed on the front surface of one side of the outer case 11. In the state where the dust collecting container 10 is accommodated in the dust collecting chamber 7 of the electric sweeper main body 1, the intake port 14 communicates with the suction hose mounting hole 3 formed in the main body 1 (refer FIG. 2). Therefore, air and dust sucked in by the suction hose (not shown) are collected in the outer case 11 from this intake port 14. The back side, which is the other side of the outer case 11, is open.

The inner case 12 is formed of resin colored in primary colors such as yellow, red, blue, and the like, and is fitted into the outer case 11 from the back side of the outer case 11 (see Fig. 4). In the fitted state, since the outer case 11 is transparent or translucent, it can be seen that the inner case 12 is disposed inside by penetrating the outer case 11. The inner case 12 cooperates with the outer case 11 in a state of being fitted to the outer case 11 to mainly pass air and dust entering the intake port 14 of the outer case 11, A turning flow path 25 for imparting centrifugal force, a bypass flow path 30 for securing a flow of air entering the intake port 14, a dust collecting space 26 where dust is collected, and a dust collecting surface 27 to be described later. To form. In addition, the turning flow path 25, the bypass flow path 30, the dust collecting space 26, and the dust collecting surface 27 are shown in FIG. 6 mentioned later.

Thus, since the revolving flow path 25 is formed by the outer case 11 and the inner case 12 in the dust collection container 10, dust collection can be performed by what is called a cyclone system. In addition, since the bypass flow path 30 is formed in the dust collecting container 10, the flow of air from the intake port 14 to the filter device 13 can be ensured even when the turning flow path 25 is blocked.

When these structures are explained in detail, as shown in Fig. 4, the front of the inner case 12 is viewed from the front of the buffer space 15 that receives the air entering the inlet 14 and the air of the buffer space 15 from the front. The turning flow path formation part 16 which guides in the direction, and the semi-convex convex part 17 protruded in the front direction inside the turning flow path formation part 16 are contained. In the peripheral surface downstream of the turning direction from the peripheral surface of the convex part 17, many ventilation holes 18 are laid. Air and dust entering the buffer space 15 from the inlet 14 flow mainly downstream along the turning channel forming portion 16 while turning clockwise in a clockwise direction. In other words, air and dust revolve around the convex portion 17. At this time, since the convex part 17 is provided with many ventilation small holes 18, the part of the air which turns is flows through the ventilation small hole 18, and flows to the back side. In this way, the plurality of vent holes 18 formed in the convex portion 17 form a bypass flow path 30 for securing the flow of air entering the intake port 14.

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

The outer case 11 is provided with a handle 19 on its upper surface side. The rear end of the handle 19 is provided with a push button 22 and a hook 23 (see Fig. 6) for locking the filter device 13 in a closed state in conjunction with the push button 22. In addition, the filter device 13 is provided with a hook support 51. The hook hole 51 is provided with a locking hole 52 penetrating in the front and rear direction, and the hook 23 is inserted into the locking hole 52 and then engaged with the hook support 51 so as to engage the filter device. (13) is closed. Moreover, by operating the push button 22, the engagement state of the hook 23 and the hook support 51 is canceled | released, and the filter apparatus 13 can be opened (removable) with respect to the outer case 11. FIG.

FIG. 5 is a diagram for explaining the flow of air flowing through the turning flow path 25 in the dust collecting container 10, and separating the outer case 11 and the inner case 12, and further, the filter device 13. The perspective view which showed the dust collection container 10 from front oblique front in the state removed from the outer case 11 is shown.

As shown by the thick line arrow in FIG. 5, air entering the intake port 14 of the outer case 11 is collected in the buffer space 15 partitioned by the inner case 12, and the convex portion from the buffer space 15 is shown. It flows first to the left direction so that it may turn clockwise from the front with respect to (17) center, and turns to the right direction centering on the convex part 17. As shown in FIG.

FIG. 6 is a view for explaining the flow of air and dust in the dust collecting container 10, and is a perspective view of the dust collecting container 10 viewed from the rear side, and showing the filter device 13 in an open state.

Referring to Fig. 6, the turning channel 25 is formed by the outer case 11 and the inner case 12, and air and dust 20 flow along the turning channel 25 (refer to the thick arrow shown in Fig. 6). ). When viewed from the back side, the guide surface 24 smoothly expanded in the convex curvature which forms the downstream inner part of the turning flow path 25 is partitioned off by the inner case 12. As shown in FIG. The guide face 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 air and dust 20 flowing through the turning flow passage 25 from the downstream side of the turning flow passage 25 to assist the turning of the air and dust 20.

A dust collecting space 26 is partitioned around the downstream side of the turning flow 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 turning flow passage 25 and the dust collecting space 26 including the guide surface 24 are referred to as the dust collecting surface 27. . That is, the dust collecting surface 27 is formed by the outer case 11 and the inner case 12. The dust collecting space 26 is partitioned by the dust collecting surface 27 on the front side, and by the filter apparatus 13 which is in the closed state on the back side. The centrifugal force is applied to the dust 20 in the air while the air flow and the dust 20 pass through the swing flow passage 25, so that the dust 20 flows outside the swing flow passage 25 and is schematically shown in FIG. 6. As shown above, the dust is collected from the outside of the dust collecting space 26.

And even if many dusts 20 gather in the dust collecting space 26, the downstream side of the turning flow path 25 has the guide surface 24 smoothly expanded by the inner case 12, and this guide surface 24 is carried out. The dust 20 is hardly adhered to it, and air can be turned in the turning flow path 25. (As shown by the broken arrow shown in the figure, the air turns.)

Therefore, even in the state where many dusts 20 are gathered in the dust collecting space 26, the flow of air of the turning flow path 25 itself is not obstructed, and air sucks and the suction force hardly falls.

Air and dust 20 flow smoothly through the revolving flow path 25, so that the dust 20 does not adhere to the guide surface 24, and can be collected smoothly from the surroundings of the dust collecting space 26. You may coat fluorine resin, such as Teflon (trademark) at the molecular level, on both the inner surface and the front and back surfaces of the inner case 12, for example. Alternatively, carbon may be deposited on the inner surface of the outer case 11 or both front and back of the inner case 12. By coating the fluorine resin at the molecular level or depositing carbon, the water repellency of the inner surface of the outer case 11 and the front and rear surfaces of the inner case 12 is improved, dust separation is improved, dirt is prevented, and resistance to flowing air It is possible to reduce the amount of dust and make the dust collecting container with improved performance.

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 as described above. In addition, the filter device 13 includes filter frames 35 and 36 that form the outer circumference, and two types of filters held by the filter frames 35 and 36.

Specifically, referring to FIG. 6, the filter frame has a two-layer structure, and the first filter frame 35 connected to the rear outer circumference of the outer case 11 and the first filter frame 35 connected to the rear surface of the first filter frame 35. It has two filter frames 36.

On the front side of the first filter frame 35, a square mesh filter 37 with fine eyes is disposed. The mesh filter 37 has a flat surface (referred to as an opposing surface) facing the outer case 11 to capture the dust 20 collected in the dust collecting space 26, and the dust 20 is rearward (FIG. 6). In the bottom of the mesh filter 37). The large dust 20 is impeded by this mesh filter 37, and the fine dust 20 can flow backward through the mesh filter 37 with the air. That is, the mesh filter 37 passes the air flowing out from the back side of the outer case 11 and captures the large dust 20. In addition, the 1st filter frame 35 and the mesh filter 37 may be collectively called a 1st filter. Moreover, the hinge 21 mentioned above is provided in the 1st filter frame 35 in the filter apparatus 13. As shown in FIG.

The second filter frame 36 is equipped with a pleated filter 34 for capturing fine dust. The pleated filter 34 is a filter which has a valley shape in which cross-sectional shapes are alternately folded in opposite directions, and are continuous. The pleated filter 34 passes the air flowing out from the back side of the outer case 11 and captures the fine dust 20. In addition, the air passing through the pleated filter 34 is discharged to the outside through an electric blower (not shown). Thus, in this filter apparatus 13, the comparatively large dust 20 is captured by the mesh filter 37, and the comparatively small dust 20 is captured by the pleated filter 34, regardless of the difference in size, the dust 20 ) Can be captured.

In order to hold the pleated filter 34, the second filter frame 36 is provided with a holding member 38 for the pleated filter 34, as shown in FIG. The holding member 38 has irregularities that match the valley shape of the pleated filter 34, and holds the end and the central portion of the pleated filter 34. In addition, since the pleated filter 34 itself is shown to be complicated, the holding member 38 is shown in FIG. 4, and the pleated filter 34 itself is omitted. In addition, the second filter frame 36 and the pleated filter 34 may be collectively referred to as a second filter. The 2nd filter is arrange | positioned with respect to the 1st filter (the 1st filter frame 35 and the mesh filter 37) on the opposite side of the outer case 11, ie, the position which is farthest back side from the outer case 11.

You may perform the coating process performed to the front side of the 1st filter frame 35, and the mesh filter 37 arrange | positioned thereon to the inner surface of the outer case 11 mentioned above, or both front and back of the inner case 12. As shown in FIG. That is, the front side of the first filter frame 35 and the mesh filter 37 may be coated at the molecular level with fluorine resin or carbon may be deposited. In this way, dust attached to the front side of the first filter frame 35 and the mesh filter 37 can be easily dropped, and the resistance to air passing through the mesh filter 37 can be reduced. can do.

FIG. 7 shows a state in which the tissue paper 40 is loaded on the mesh filter 37 in FIG. As shown in FIG. 6, the mesh filter 37 is provided in the front side (upper surface side in FIG. 6) of the filter apparatus 13, and the captured dust 20 of the mesh filter 37 It is captured on the opposite surface to the outer case 11 and collected in the dust collecting space 26.

In the case where the dust 20 collected in the dust collecting container 10 is discarded, the dust 20 collected on the opposite surface of the dust collecting space 26 or the mesh filter 37 by opening the filter device 13 with respect to the outer case 11. Throw away. In this case, the fine dust 20 adheres to the opposing surface of the mesh filter 37 and the mesh of the mesh filter 37 may be clogged or the dust 20 attached to the mesh filter 37 may be difficult to discard.

Therefore, in this embodiment, as shown in FIG. 7, the dust 20 captured by placing the tissue paper 40 on the mesh filter 37 is collected on the tissue paper 40, and the filter device (with respect to the outer case 11) is used. 13), it is easy to discard the captured dust 20. That is, in the state shown in FIG. 7, when the tissue paper 40 is placed on the mesh filter 37 and the filter device 13 and the outer case 11 are closed to each other, the filter device 13 and the outer case 11 are closed. By this, the tissue paper 40 can be fitted and can be mounted between them. Thereby, since the dust 20 can be captured by the tissue paper 40 before the filter apparatus 13, the filter apparatus 13 can be extended. In addition, when the tissue paper 40 is dirty with the dust 20, maintenance is easy because only the new tissue paper 40 is replaced.

As described above, the opposing surface that traps the dust 20 in the mesh filter 37 is flat (see FIG. 6). Therefore, of course, when the filter device 13 is opened with respect to the outer case 11, the opposing surface of the mesh filter 37 is upward, and if not, the tissue paper on the opposing surface of the mesh filter 37 is not. Unexpected overflow of the dust 20 contained in 40 causes the inconvenience of soiling the floor (see Fig. 7). In addition, the same inconvenience occurs even when the tissue paper 40 is not used.

FIG. 8 shows an embodiment to which the present invention is applied in FIG. FIG. 9 shows an embodiment to 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 inconvenience, the mesh filter 37 has the storage part 41 as shown in FIG. The storage part 41 is formed in three dimensions by the main surface 28 and the side surface 29 which oppose the outer case 11. Specifically, the main surface 28 is an approximately trapezoidal inclined surface connected to the periphery of the hook receiver 51 side of the first filter frame 35 while widening from the hinge 21 side toward the hook receiver 51. . The side surface 29 stands in the cross direction of the main surface 28 from the end of the main surface 28 (except the hook support 51 side), and excludes the periphery (hook support 51) side of the first filter frame 35. It is an inclined surface connected to). That is, the reservoir 41 is wide and shallow from the hinge 21 side toward the opposite side (the hook support 51 side) of the hinge 21 side with respect to the reservoir 41, and has a bottom plate shape, details. Preferably, hinge 21 side is formed in the shape of a trap which becomes a grip part side.

Therefore, when the tissue paper 40 is loaded on the mesh filter 37, the tissue paper 40 deforms according to the shape of the reservoir 41 of the mesh filter 37 as shown in FIG. It becomes a trap shape similar to (41). As a result, when the filter device 13 is opened with respect to the outer case 11, the dust 20 loaded on the tissue paper 40 overflows from the surroundings of the tissue paper 40 even when the reservoir 41 is not leveled. The dust 20 and the tissue paper 40 can be smoothly discarded from the hook receiving side 51 in the storage portion 41 without being blown off or flying off.

And as shown in FIG. 10, holding the handle 19 in the state which the outer case 11 and the filter apparatus 13 open each other, and inclining the whole dust collection container 10 so that the hook holder 51 side may become downward. The back tissue paper 40 and the dust 20 on the tissue paper 40 slide downwards away from the hinge 21 side (see the thick line arrow shown). If a trash can (not shown) is disposed first, the dust 20 may be thrown into the trash without flowing onto the floor.

8, the back shape of the outer case 11 and the inner case 12 is a shape different from that shown in FIG.

In detail, a rib (compression) protruding toward the mesh filter 37 on the side close to the guide surface 24 of the inner case 12, that is, on the left side in FIG. The seal compartment rib 42 is provided integrally.

In addition, a rib (dust collecting) having a curved shape (approximately C-shaped from the back) that partitions the dust collecting surface 27 along the convex portion 17 described above is provided on the substantially right upper portion on the rear side of the inner case 12. The surface partition rib 43 is provided integrally. The dust collection surface partition rib 43 partitions the upper right side in FIG. 8 of the dust collection surface 27, and protrudes toward the mesh filter 37 side.

In the right part in Fig. 8 on the dust collecting surface 27, ribs (called bypass flow path partitioning ribs 44) protruding toward the mesh filter 37 side continuously after the dust collecting surface partitioning rib 43 are referred to. It is installed integrally. The bypass flow path partition rib 44 has a substantially L-shape as viewed from the rear, and partitions the lower side in FIG. 8 of the bypass flow path 30. Moreover, between the bypass flow path 30, the turning flow path 25, and the dust collection space 26 is partitioned by the dust collection surface division rib 43 and the bypass flow path division rib 44 which are mutually continuous.

And inside the bypass flow path 30, the convex part 17 is provided with the wall (referred to as the turning wall 45) extended to the back side by the substantially reverse S-shape from the back surface. By providing the swing wall 45, the bypass flow path 30 is provided with a substantially C-shaped swing flow path (referred to as a swing flow path 46 in the bypass). As a result, the air flowing through the vent hole 18 and flowing into the bypass flow path 30 inside the convex portion 17 is turned counterclockwise from the rear side in the turning flow path 46 in the bypass. (See dashed-dotted arrow shown). At this time, centrifugal force is applied to the dust 20 in the air. As a result, the dust 20 can be separated from the air passing through the bypass flow path 30. Here, the swivel wall 45 extends linearly to the hook 23 side along the flow direction of the air in the bypass flow path 30 at the right end in FIG.

These compression chamber compartment ribs 42, dust collecting surface compartment ribs 43, bypass flow path compartment ribs 44, and the swivel wall 45 are further backside from the back side periphery of the outer case 11, that is, the mesh filter. It protrudes toward the side (37) (refer FIG. 12), and each protruding part is stored in the storage part 41 of the mesh filter 37 when the outer case 11 and the filter apparatus 13 are closed mutually. In particular, the dust collecting surface partition rib 43, the bypass flow path partition rib 44, and the turning wall 45 are components on the inner case 12 side, and the inner case 12 protrudes from the outer case 11. I can speak. However, since the protruding portion of the inner case 12 is stored in the storage portion 41, the dust collecting container 10 does not become as large as the portion of the inner case 12 protruding from the outer case 11. Inhibition of enlargement of size (10) can be aimed at. In addition, when the outer case 11 and the filter device 13 are closed with each other, the dust collecting surface 27 and the reservoir 41 face each other.

In addition, when the tissue paper 40 is placed on the mesh filter 37 and the outer case 11 and the filter device 13 are closed to each other, the compression chamber compartment rib 42 and the dust collecting surface compartment rib 43 shown in FIG. The bypass flow path partition rib 44 pushes the tissue paper 40 onto the filter device 13 so as to follow the trap shape of the reservoir 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 to have a trap shape substantially equal to the shape of the storage portion 41.

In addition, while the tissue paper 40 is positioned, the first compression chamber is located between the compression chamber partition rib 42 and the side surface 29, the main surface 28, and the dust collecting surface 27 on the left side in FIG. 47 (compression chamber) is formed. That is, the compression chamber division rib 42 partitions the 1st compression chamber 47. Moreover, the 2nd compression chamber 48 (compression chamber) is formed between the dust collection surface division rib 43, the bypass flow path division rib 44, the main surface 28, and the dust collection surface 27. As shown in FIG. In addition, a third compression chamber 49 (compression chamber) is formed between the portion extending in the hook 23 side in the swing wall 45 and the side surface 29 on the right side in FIG. 8. . In addition, the 1st compression chamber 47, the 2nd compression chamber 48, and the 3rd compression chamber 49 are shown in the back side of the outer case 11 and the inner case 12 for convenience of description. Here, it can be said that the 1st compression chamber 47 and the 2nd compression chamber 48 are provided in the dust collection surface 27, and the 3rd compression chamber 49 is provided in the pie path flow path 30. As shown in FIG. Moreover, the 1st compression chamber 47, the 2nd compression chamber 48, and the 3rd compression chamber 49 are provided in the periphery side of the storage part 41, and the center of the storage part 41 (in detail) The center of the main surface 28).

In this manner, the compression chamber partition rib 42 may position the tissue paper 40 in addition to partitioning the first compression chamber 47. The dust collecting surface partition rib 43 may also position the tissue paper 40 in addition to partitioning the dust collecting surface 27. The bypass flow path partition rib 44 may position the tissue paper 40 in addition to partitioning the bypass flow path 30. Therefore, it is not necessary to separately install the part which positions the tissue paper 40, and the dust collection container 10 can be comprised easily.

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

In addition, the compression chamber compartment rib 42, the dust collecting surface compartment rib 43, and the bypass passage compartment rib 44 push the tissue paper 40 to the filter device 13 so as to conform to the shape of the reservoir 41. Therefore, the tissue paper 40 can be mounted without tearing.

And the dust collection surface 27 opposes the storage part 41 which collects the dust 20 as mentioned above, and the dust 20 provided with the centrifugal force to the turning flow path 25 is the dust collection surface 27 and the storage part. It collects in between 41 (the dust collection space 26 side), and part of it is taken in by the 1st compression chamber 47. As shown in FIG. This dust 20 is subsequently compressed by the dust 20 taken in in the 1st compression chamber 47 (refer the solid arrow shown). In the first compression chamber 47, when the dust 20 is picked up until the compression chamber is full, the dust 20 flowing along the turning flow passage 25 is collected in the second compression chamber 48, and this time is made. It is compressed similarly to the case in the 1 compression chamber 47 (refer to the broken-line arrow shown). Thus, since the 1st compression chamber 47 and the 2nd compression chamber 48 are provided in the dust collecting surface 27, the dust 20 closes between the dust collecting surface 27 and the storage part 41 early. Can be prevented. Thereby, the dust collection capability of the dust collection container 10 can be improved.

In addition, the inside of the convex portion 17, that is, the dust 20 flowing through the bypass flow path 30 is rotated counterclockwise from the back while being given a centrifugal force as described above, so that the outside of the turning flow path 46 in the bypass. It flows into the 3rd compression chamber 49, it collects, and is compressed similarly to the case of the 1st compression chamber 47 and the 2nd compression chamber 48 (refer to the dashed-dotted line arrow shown). Thus, since the 3rd compression chamber 49 is installed in the bypass flow path 30, the dust 20 isolate | separated from the air in the turning flow path 46 in a bypass can be compressed, and the bypass flow path 30 is a dust. The blockage can be prevented early by (20). Thereby, the dust collection capability of the dust collection container 10 can be improved.

Moreover, as mentioned above, the 1st compression chamber 47, the 2nd compression chamber 48, and the 3rd compression chamber 49 are arrange | positioned in the position away from the center of the storage part 41. As shown in FIG. Here, the center of the reservoir 41 is a position where suction force tends to be concentrated when the electric cleaner main body 1 is operated, and the first compression chamber 47 and the second compression chamber 48 which collect the dust 20 are used. And the fall of a suction force can be suppressed by removing the 3rd compression chamber 49 from the center of the storage part 41. 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 to each other. 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 to each other and placed on the floor surface. FIG. 13 shows a state in which the dust collecting container 10 is held in the air while holding the handle 19 in FIG.

As shown in FIG. 11, the back side edge (right side edge in FIG. 11) of the outer case 11 and the periphery of the storage part 41 of the mesh filter 37 which oppose this (in FIG. The left peripheral edge is formed to be inclined with respect to the passage direction X of air flowing out from the back side of the outer case 11 when the outer case 11 and the filter device 13 are closed to each other. Thereby, compared with the case where the peripheral edge of the storage part 41 orthogonally crosses the passage direction X of air, in the storage part 41, the air which flows out from the outer case 11 can be made to pass, The main surface 28 and the side surface 29 which form the storage part 41 can be enlarged. Therefore, it is possible to prevent the reservoir 41 from being blocked early by the dust 20. 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 trapping of the dust 20 in the mesh filter 37 can be increased.

In addition, as shown in FIG. 12, the back side edge (upper edge in FIG. 12) of the outer case 11 and the periphery (upper edge in FIG. 12) of the storage portion 41 are the outer case 11. ) And the filter device 13 are formed so as to be substantially continuous in the horizontal direction. Therefore, the tissue paper 40 can be easily mounted on the reservoir 41, and the tissue paper 40 can be prevented from overflowing from the reservoir 41.

In addition, the pleated filter 34 and the second filter frame 36 have a rotational axis (axis of the hinge 21) with respect to the outer case 11 of the first filter frame 35 as shown in FIG. Is rotatably connected with respect to the first filter frame 35 about the axis 57 at different positions. Here, when the outer case 11 and the filter device 13 are opened to each other while holding the handle 19 and the dust collecting container 10 is in the air, the second filter frame 36 is connected to the first filter frame 35. It rotates downward with respect to the 1st filter frame 35 and the 2nd filter frame 36 open. Thereby, the above-mentioned pleated filter 34 is exposed between the 1st filter frame 35 and the 2nd filter frame 36, and this can be taken out.

As such, the rotational axis 57 of the second filter frame 36 and the rotational axis of the first filter frame 35 (the axis of the hinge 21) are in different positions, so that they are the same as those of the first case. The second filter frame 36 and the pleated filter 34 are easily rotated (easy to open) with respect to the filter frame 35. Therefore, the dust 20 captured by the pleated filter 34 can be discarded smoothly. As a result, the dust collection container 10 can be handled easily.

14 is a side sectional view of the dust collecting container 10 with the tissue paper 40 inserted and the outer case 11 and the filter device 13 closed.

As described above, the hook device 51 is provided in the filter device 13 (in detail, the second filter frame 36), and the locking hole 52 is formed in the hook support 51 (see Fig. 8). .

When the hook 23 provided in the outer case 11 is engaged with the hook support 51, as shown in FIG. 14, the front (right side in FIG. 14) of the hook 23 is located in the locking hole 52. As shown in FIG. Enter. At this time, the part located in the locking hole 52 in the tissue paper 40 is fitted to the hook 23 and the hook support 51. As a result, it becomes difficult for the hook 23 to be engaged with the hook support 51, or, conversely, the engagement state between the hook 23 and the hook support 51 becomes difficult to release, or the tissue paper 40 is further removed from the hook ( There is a risk of tearing at the portion sandwiched between 23 and the hook support 51. In addition, if the tissue paper 40 is made smaller so as not to be sandwiched between the hook 23 and the hook support 51, the so-called fitting range becomes smaller as a whole, so that the tissue paper is between the outer case 11 and the filter device 13. 40 becomes difficult to fit.

FIG. 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 applies a modified example in FIG.

In order to eliminate the above inconvenience, the disposable sheet 53 shown in Figs. 15 and 16 is applied.

In detail, when the disposable sheet 53 is mounted on the mesh filter 37 in the disposable sheet 53, the portion close to the hook holder 51 is cut out. That is, the V-shaped concave groove 58 as shown in FIG. 15 is formed in the disposable sheet 53. As shown in FIG. As a result, as shown in Fig. 16, the disposable sheet 53 can be mounted on the mesh filter 37 in a concave groove 58, away from the hook support 51. Therefore, when the outer case 11 and the filter apparatus 13 are mutually closed, the disposable sheet 53 does not fit in the hook 23 and the hook support 51, and can eliminate the inconvenience mentioned above. Moreover, in this disposable sheet 53, the fitting range required for fitting to the outer case 11 and the filter apparatus 13 in parts other than the recessed groove 58 can be ensured.

In addition, as a modification of the disposable sheet 53, as shown in Fig. 17, the concave groove 58 may have a semicircular shape.

18 is a plan view of the lifting edge 54 attached to the dust collecting container 10. As shown in FIG. 19 is a side sectional view of the dust collecting container 10 when the filter device 13 is opened and the dust 20 is discarded with respect to the outer case 11. 20 is a diagram showing the net 56 in FIG.

When the dust 20 of the dust collecting container 10 is discarded, it can be performed more smoothly by using the rising edge 54 shown in FIG.

The rising edge 54 is a substantially rectangular edge shape similar to the periphery of the mesh filter 37 and is supported by the hinge 21 (see Fig. 19). The lift edge 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 rising edge 54 and the outer case 11. And, as shown in Fig. 19, when the filter device 13 is opened with respect to the outer case 11, and this is rotated downward, the floating edge 54 is in a substantially horizontal position, and although not shown, the rising edge The tissue paper 40 is loaded on 54. However, since the floating edge 54 has a substantially rectangular edge shape as described above, the inside is spaced. Thus, the dust 20 on the tissue paper 40 is biased to the inner part of the rising edge 54 in the tissue paper 40 so that the tissue paper 40 is deformed into a bag shape and the rising edge 54 It falls to the trash can 55 from the inside of the trash bin. Here, the tissue paper 40 is changed into a bag shape, so that the dust 20 is wrapped in the tissue paper 40, so that it rarely rises from the tissue paper 40.

In addition, as shown in FIG. 20, the net 56 may be struck inside the lifted edge 54. This net 56 has elasticity and a hole is drilled at the center position thereof. Therefore, the tissue paper 40 which loaded the dust 20 deforms into a bag shape certainly when it passes through the hole of the net 56, and falls to the trash bin 55. As shown in FIG. Thereby, the flying off of the dust 20 from the tissue paper 40 can fully be prevented.
