Furthermore, since the tissue paper placed on the facing surface is recessed along the facing surface, the tissue paper can reliably collect the captured dust, and the rotating part approaches the fixed part. When the paper is rotated, the tissue paper tends to become a bag.

According to the sixth aspect of the present invention, the dust collecting container attached to and detached from the vacuum cleaner main body includes a case in which a suction port is formed on one side and the other side is open, and a filter device. .
The filter device has one end connected to the case via a hinge, and can rotate around the hinge between an open position where the other side of the case is open and a closed position where the other side of the case is closed It is. In the dust collection container, air and dust are taken into the case from the suction port and flow out from the other side of the case. At this time, the filter device in the closed position allows air to pass but captures dust. .

The filter device is provided with a facing surface facing the other surface side of the case in the closed position, and the facing surface is formed of a breathable mesh. In the filter device in the closed position, the air-permeable mesh on the opposite surface captures dust. Since the facing surface is recessed toward the downstream side in the air flow direction, the captured dust can be reliably collected.
Since the tissue paper is mounted on the facing surface along the recessed portion, the tissue paper can capture dust prior to the breathable mesh on the facing surface. Thereby, the early clogging of a breathable mesh can be suppressed. Here, since the tissue paper mounted on the opposing surface has a shape that is recessed along the recessed portion of the opposing surface, the tissue paper can reliably collect the captured dust. Then, if the tissue paper is discarded by rotating the filter device to the open position, the dust captured by the tissue paper can be discarded together.

Here, the dust collecting container has a flow path member. The flow path member has a tubular shape having an inlet communicating with the suction port and an outlet facing the opposing surface when the filter device is in the closed position, and can be rotated around the inlet side in the recessed portion of the opposing surface. Is supported by the filter device.
In the flow path member, the first pressing portion provided on the outlet side presses the tissue paper mounted on the opposing surface against the opposing surface, and the second pressing portion provided on the inlet side presses another tissue paper. Take it and press it against the inside of the case. Thereby, in a state where the filter device is in the closed position, the flow path member is disposed between the tissue paper mounted on the opposite surface and another tissue paper, and these two pieces of tissue paper flow. It becomes the bag shape which has the internal space where a road member is arrange | positioned. At this time, since the flow path member presses the tissue paper bag against the opposing surface and the inner surface of the case, the tissue paper bag is positioned while maintaining the bag-like shape.

In this case, the dust taken into the case from the suction port enters the flow path member from the inlet and then flows into the tissue paper bag from the outlet. At this time, the dust is captured by the tissue paper and the tissue paper bag. Accumulate inside.
Therefore, the dust trapped in the tissue paper is discarded in a state where it is collected inside the tissue paper bag when the garbage is thrown away, so that the dust can be prevented from rising from the tissue paper.

According to the seventh aspect of the present invention, the binding portion of the dust collecting container includes the engaging portion provided on the peripheral portion of the opposing surface of the filter device and the engaged portion provided on the peripheral portion on the other surface side of the case. Including joints. The engaged portion is engaged with the engaging portion when the filter device is rotated to the closed position.
Here, when the filter device is rotated to the closed position, the binding portion is received by the peripheral edge portion of the tissue paper and the second pressing portion of the flow path member that are mounted along the recessed portion of the opposing surface. The tissue paper is bound between the engaging portion and the engaged portion and bound. Thereby, the dust accumulated inside the bag by these two sheets of tissue paper is confined in the bag, so that it is possible to reliably prevent the dust from rising from the tissue paper.

According to invention of Claim 8, the 1st cut member which a dust container has is supported by the case in the state penetrated by the suction inlet of the case, and protruded in the case and the 1st position which protruded out of the case It can move to the second position.
The first cut member moves to the second position when the dust collecting container is attached to the main body of the vacuum cleaner, and is applied to the inlet of the flow path member in the tissue paper received by the second pressing portion of the flow path member. Cut off the other parts from the rest. As a result, the entrance is not blocked by the tissue paper, so that dust and air taken into the case from the suction port can smoothly pass through the flow path member from the inlet and flow into the tissue paper bag. Can do.

Here, since the second pressing portion on the inlet side presses the tissue paper received on the inner surface of the case, the position of the portion of the tissue paper that is in contact with the inlet is stable. Can smoothly cut this part.
According to the invention of claim 9, since the second pressing portion is formed of a soft material, the received tissue paper can be pressed (adhered) to the inner surface of the case without a gap. This prevents dust and air taken into the case from the suction port from escaping into the gap between the inner surface of the case and the tissue paper, and ensures that these dust and air pass through the flow path member from the inlet. Can flow into the tissue paper bag.

In addition, since the second pressing portion formed of a soft material causes the tissue paper received to adhere to the inner surface of the case, the portion of the tissue paper that is in contact with the entrance is less likely to slip (the second pressing portion is slippery of this portion). The first cut member described above can smoothly cut this portion.
According to the tenth aspect of the present invention, the second urging member of the dust collecting container is such that the first pressing portion is separated from the facing surface when the filter device is rotated from the closed position toward the open position. Energize the flow path member. Thereby, when the filter device is in the open position, the first pressing unit does not press the tissue paper mounted on the facing surface against the facing surface. Further, when the filter device is in the open position, the flow path member on the filter device side is separated from the inner surface of the case, so that the second pressing portion does not press another tissue paper against the inner surface of the case.

As a result, the two tissue paper bags can no longer be positioned on the dust collecting container, so that the tissue paper bag having dust accumulated therein can be smoothly removed from the dust collecting container and discarded.
According to the invention of claim 11, the rib provided on the inner surface of the case has a tissue connected to the opposing surface between the tissue paper received by the second pressing portion and the inner surface of the case. Hold the paper.

  As a result, the air that has flowed into the tissue paper bag passes through the tissue paper pressed against the opposing surface by the first pressing portion and passes not only to the first flow path toward the opposing surface but also to the second pressing portion. After passing through another tissue paper that has been received, the second flow path toward the opposite surface via the space can also flow. Therefore, not only the tissue paper pressed against the opposing surface by the first pressing unit, but also another tissue paper received by the second pressing unit can capture the dust on the flowing air. The dust capturing efficiency can be improved.

According to invention of Claim 12, the dust collecting container attached to or detached from the vacuum cleaner body has a case in which a suction port is formed on one side and the other side is opened, and a filter device. .
The filter device has one end connected to the case via a hinge, and can rotate around the hinge between an open position where the other side of the case is open and a closed position where the other side of the case is closed It is. In the dust collection container, air and dust are taken into the case from the suction port and flow out from the other side of the case. At this time, the filter device in the closed position allows air to pass but captures dust. .

The filter device is provided with a facing surface that faces the other surface side of the case in the closed position. In the filter device in the closed position, the opposing surface captures dust. Since the facing surface is recessed toward the downstream side in the air flow direction, the captured dust can be reliably collected.
Here, the dust collecting container has a basket portion accommodated in a recessed portion of the facing surface so as to be positioned between the other surface side of the case and the facing surface. The basket portion is a bathtub-like shape having an opening at a position facing the other side of the case, and tissue paper is mounted three-dimensionally along the internal shape so that the end protrudes from the opening, and the opening is covered with a lid. Another tissue paper is attached to make it.

  Thereby, between the other side of the case and the opposing surface, there is a bag of two tissue papers attached to the basket portion. Therefore, the dust taken into the case from the suction port and flowing out from the other side of the case is captured by the tissue paper bag and collected inside the bag prior to the opposing surface. Thereby, the early clogging of the filter apparatus in an opposing surface can be suppressed.

When the filter device is rotated to the open position and the tissue paper bag is discarded, the dust captured by the tissue paper can also be discarded. In particular, the dust trapped in the tissue paper is thrown away in a state where it is collected inside the tissue paper bag when the garbage is thrown away, so that the dust can be prevented from rising from the tissue paper.
According to the thirteenth aspect of the present invention, the binding portion of the dust collecting container includes the engagement portion provided at the portion of the basket portion that borders the opening and / or the peripheral portion of the opposing surface, and the other surface side of the case. And an engaged portion provided at the peripheral edge portion. The engaged portion is engaged with the engaging portion when the filter device is rotated to the closed position.

  Here, when the filter device is rotated to the closed position, the binding portion includes a peripheral portion of the tissue paper attached along the internal shape of the basket portion and a peripheral portion of the tissue paper covering the opening. Stitching between the engaging portion and the engaged portion. Thereby, the dust accumulated inside the bag by these two sheets of tissue paper is confined in the bag, so that it is possible to reliably prevent the dust from rising from the tissue paper.

  According to invention of Claim 14, when the 2nd cut member provided so that it may protrude to the other surface side while fringing the suction inlet in the inner surface of a case rotates a filter apparatus from an open position to a closed position In the tissue paper covering the opening, a hole is made in the portion covering the opening. Thereby, the dust taken into the case from the suction port can be reliably stored inside the tissue paper bag by passing through the hole opened by the second cut member.

  In the vacuum cleaner body 2, an intake port 7 is formed on the front surface, and an exhaust port 8 is formed on the rear surface. An air flow path 9 communicating with the intake port 7 and the exhaust port 8 is defined in the vacuum cleaner body 2. In the air flow path 9, a vacuum cleaner dust collection container (hereinafter sometimes abbreviated as “dust collection container”) 10 and an electric blower 11 are connected to the intake port 7 → the dust collection container 10 → The electric blower 11 is arranged so as to be aligned with the exhaust port 8. The dust collecting container 10 can be attached to and detached from the vacuum cleaner main body 2 from above, for example, by opening a front side portion of the top surface 2A of the vacuum cleaner main body 2.

The hose 3 is a flexible bellows hose and can be bent into an arbitrary form. In the hose 3, a connecting cylinder 12 is coupled to one end (the rear end in FIG. 1). Specifically, one end of the hose 3 is accommodated inside the connection cylinder 12. In this state, one end of the hose 3 and the connecting cylinder 12 are substantially coaxial.
The connecting cylinder 12 is inserted from the front side with respect to the air inlet 7 and is connected to the dust collecting container 10. Thereby, the inside of the hose 3 communicates with the inside of the dust collecting container 10.

An auxiliary handle 13 is provided on the upper outer peripheral surface of the connecting cylinder 12. The vacuum cleaner body 2 can be easily moved by grasping the auxiliary handle 13 together with the folding handle 6 described above.
When the operation of the electric vacuum cleaner main body 2 is started, the electric blower 11 is driven by receiving electric power, thereby generating a suction force. Due to this suction force, the dust on the floor surface X is sucked into the above-described suction tool (not shown), passes through the suction tool, the pipe (not shown), and the hose 3 in this order, and then the inlet 7 To the air flow path 9 of the vacuum cleaner body 2. Further, the air around the suction tool (not shown) is sucked up to the air flow path 9 together with the dust on the floor surface X.

The air and dust sucked up to the air flow path 9 are first separated in the dust collecting container 10. Thereby, while dust is collected in the dust collecting container 10, air is discharged by the electric blower 11 to the downstream side of the electric blower 11 in the air flow direction in the air flow path 9. The discharged air is discharged from the exhaust port 8 to the outside of the machine.
<Dust collection container for electric vacuum cleaner>
Next, the dust container 10 (for a vacuum cleaner) will be described. Here, in this embodiment, there are three examples from the first to the third for the dust collecting container 10, and in the following, the respective examples are in the order of the first example, the second example, and the third example. The dust collecting container 10 will be described.
(1) 1st example FIG. 3: is the perspective view which looked at the dust collecting container 10 which concerns on a 1st example from the upper right front. FIG. 4 is a right sectional view of the dust collecting container 10. FIG. 5 shows a state where the filter device 21 is rotated away from the case 20 in the dust collecting container 10.

With reference to FIG. 3, the dust collecting container 10 includes a case 20 and a filter device 21.
The case 20 has a box shape in which the front side corner is substantially perpendicular. The case 20 is formed of, for example, a transparent or translucent resin, and the inside thereof can be seen through. A suction port 22 is formed on the front surface which is one surface of the case 20. The back side that is the other side of the case 20 is open. Plate-shaped guide rails 19 extending vertically are integrally provided at both ends in the width direction of the inner surface of the case 20 (see FIG. 5). A suction port 22 is located between the left and right guide rails 19 (see FIG. 5).

A handle 23 is provided on the upper surface of the case 20. By grasping the handle 23, the entire dust collecting container 10 can be moved.
The filter device 21 is attached to the other surface side (back surface side) of the case 20. The filter device 21 includes a resin filter frame and two types of filters held by the filter frame.

Specifically, the filter frame has a two-layer structure, and includes a first filter frame 24 connected to the outer peripheral edge of the back surface of the case 20 and a second filter frame 25 connected to the back surface of the first filter frame 24. Have.
Both the first filter frame 24 and the second filter frame 25 have a frame shape that forms a substantially square shape when viewed from the front.

  One end portion of the filter device 21 (the lower end portion of the first filter frame 24) is connected to one end portion (lower end portion) of the case 20 via a hinge 26. Therefore, the filter device 21 can be rotated with respect to the case 20 around the hinge 26 to open and close the filter device 21. In other words, the filter device 21 is centered on the hinge 26 between an open position where the back side of the case 20 is opened (the other side described above) and a closed position where the back side of the case 20 is closed. It can be rotated.

3 and 4 show a state where the filter device 21 is closed and in the closed position (a state where the dust collecting container 10 is completed). When the filter device 21 is rotated away from the case 20 in this state, the filter device 21 opens and reaches the open position as shown in FIG.
Referring to FIG. 4, in relation to opening and closing of the filter device 21, a button 27 and a button 27 are integrally provided on the rear end side (right end side in FIG. 4) of the handle 23 in the case 20. Hooks 28 are provided. A hook receiver 29 is provided at the upper end of the second filter frame 25. The hook receiver 29 is formed with a locking hole 30 that penetrates the hook receiver 29 in the front-rear direction.

The filter device 21 is kept closed by inserting the hook 28 into the locking hole 30 and then engaging with the hook receiver 29. On the other hand, when the button 27 is pressed, the engagement state between the hook 28 and the hook receiver 29 is released, and the filter device 21 can be opened (disposed in the open position) with respect to the case 20 (see FIG. 5). .
A filter unit 31 is disposed in the first filter frame 24. A hatched portion in FIG. 4 is a cross section of the filter unit 31. The filter unit 31 protrudes from the first filter frame 24 to the front side (left side in FIG. 4) while being disposed in the inner region of the frame-shaped first filter frame 24. The filter unit 31 faces the other surface side (back side) of the case 20 in the filter device 21 in the closed state (closed position).

With reference to FIG. 5, the filter unit 31 includes a support frame 32 and a rotation member 33.
The support frame 32 is made of, for example, resin, and has a concave shape that is recessed toward the downstream side (in FIG. 5, the back side in the drawing) in the air flow direction (see the thick broken line arrow in FIG. 2) in the dust collection container 10. ing. With reference to the posture of FIG. 5, the outline (outer peripheral edge) of the support frame 32 has a substantially rectangular shape. Three through holes 41 (engaged portions) are formed at intervals in the width direction on one side (upper side in FIG. 5) peripheral portion 32A of the support frame 32. Connecting shafts 34 extending in the width direction are integrally provided at both ends in the width direction of the deepest portion in the concave shape of the support frame 32.

With reference to the posture of FIG. 5, in the support frame 32, a region A between the left and right connecting shafts 34 and the one side peripheral edge portion 32 </ b> A is open over almost the entire area. The region B between the peripheral portion 32B (lower side in FIG. 5) is open over almost the entire region.
The support frame 32 is provided with a fixed filter 35 (fixed portion) so as to close the open area A described above. The fixed filter 35 is a hatched portion extending to the upper right in FIG. 5 and is formed of a breathable mesh. Here, the portion of the support frame 32 in which the through hole 41 is provided is the end portion of the fixed filter 35 that is farthest from the connecting shaft 34.

  The rotating member 33 is provided in the aforementioned open area B of the support frame 32. The rotating member 33 includes a substantially U-shaped movable frame 36 that is recessed downward based on the posture of FIG. 5, and a rotating filter that is held by the movable frame 36 so as to close an inner portion of the U-shape of the movable frame 36. 37 (rotating part). The rotating filter 37 is a hatched portion extending to the lower right in FIG. 5 and is formed of a breathable mesh.

  The movable frame 36 is curved so as to bulge rearward when viewed from the width direction, and the rotation filter 37 is also curved in the same manner as the movable frame 36 (see FIG. 4). Guide members 38 are integrally provided at both ends in the width direction at the portion of the movable frame 36 that forms the bottom of the U-shape (the lower end in FIG. 5), and three protrusions 39 (engagement between the left and right guide members 38). Are formed integrally at intervals in the width direction.

These guide members 38 and protrusions 39 are provided so as to protrude toward the near side in the posture of FIG. Each guide member 38 has a thin plate shape in the width direction, and the left guide member 38 is integrally provided with a columnar guide shaft 40 protruding leftward, and the right guide member 38 is provided rightward. A protruding cylindrical guide shaft 40 is integrally provided.
In the U-shaped movable frame 36, the upper left end portion 36A in FIG. 5 is connected to the left connecting shaft 34 of the support frame 32. In the U-shaped movable frame 36, the upper right end portion in FIG. 36 </ b> B is connected to the connecting shaft 34 on the right side of the support frame 32. As a result, the entire rotation member 33 can rotate about the left and right connecting shafts 34. From this, it can be seen that the rotation filter 37 of the rotation member 33 is rotatably connected to the fixed filter 35 provided on the support frame 32 via the connection shaft 34. Further, the portion of the movable frame 36 where the guide member 38 (including the guide shaft 40) and the projection 39 are provided is connected to the fixed filter 35 and the rotary filter 37 (the connection shaft 34 described above) in the rotary filter 37. Is the end furthest away from.

Specifically, the rotation member 33 is rotatable between a normal position (see FIGS. 4 and 5) and a rotation position (see FIG. 10 described later).
When the rotating member 33 is in the normal position, the fixed filter 35 and the rotating filter 37 are continuous, and these are combined to form an opposing surface 42, which has a concave shape that is recessed along the support frame 32 (see FIG. (See also 4). Further, the rotation member 33 in the normal position closes the above-described open region B of the support frame 32. Therefore, there is almost no gap between the rotating member 33 and the support frame 32. Here, when the filter device 21 is in the closed position, the above-described facing surface 42 faces the open back side of the case 20, and the air flow direction in the filter device 21 (the thick broken line in FIG. 2). It is recessed downstream (see arrow). At this time, in the movable frame 36 of the rotating member 33, the guide member 38 and the protrusion 39 are in the vicinity of the other peripheral edge portion 32 </ b> B of the support frame 32.

On the other hand, with the posture of FIG. 5 as a reference, the turning member 33 in the normal position is turned so that the lower portion thereof rises while coming to the near side of FIG. Then, in the rotating member 33, the rotating filter 37 approaches the fixed filter 35 while rotating.
When the rotating member 33 is fully rotated, the rotating member 33 reaches the rotating position (see FIG. 10). When the rotation member 33 is in the rotation position, the rotation filter 37 faces the fixed filter 35, and the rotation filter 37 and the fixed filter 35 in the opposed state form water droplets as viewed from the width direction. A space C is partitioned (see FIG. 10). When the rotation member 33 is rotated to the rotation position, the protrusions 39 on the rotation member 33 side are fitted into the through holes 41 at the same position in the width direction on the one side peripheral edge portion 32A of the support frame 32 (see FIG. 10).

Here, a first urging member (not shown) such as a torsion spring is attached to the left and right connecting shafts 34, and the urging member 33 is positioned at the normal position by the urging member. Always energized.
Referring to FIG. 4, a pleat filter 50 is provided in an inner region of the second filter frame 25. The plane cross section of the pleated filter 50 has a continuous valley shape that is alternately folded in the opposite direction.

  During the operation of the vacuum cleaner main body 2, in this (completed) dust collecting container 10, the air taken into the air flow path 9 described above is contained in the dust collecting container 10 from the suction port 22 of the case 20 together with dust. (See the thick dashed arrow in FIG. 2). Then, these air and dust flow out from the opened back side of the case 20, and in the filter device 21, either the rotating filter 37 or the fixed filter 35 on the facing surface 42, and the pleat filter 50, Try to flow in this order.

  At this time, air passes through any of the filters in the filter device 21, but relatively large dust contained in the air is caused by one of the air-permeable meshes of the rotating filter 37 and the fixed filter 35 (opposing surface 42). The relatively small dust trapped and contained in the air (fine dust that could not be captured by the facing surface 42) is captured by the pleated filter 50. Thus, in the closed position, the filter device 21 allows air flowing out from the back side of the case 20 to pass through, but captures dust. As described above, the facing surface 42 of the filter device 21 is recessed toward the downstream side in the air flow direction (see the thick broken line arrow in FIG. 2), so that the captured dust can be reliably collected.

  Here, as described above, since both the rotating filter 37 and the fixed filter 35 (opposing surface 42) are formed of a breathable mesh, there is a possibility of clogging when dust is captured to some extent. Therefore, in the dust collecting container 10, the tissue paper P can be disposed on the upstream side (left side in FIG. 4) of the rotating filter 37 and the fixed filter 35 (opposing surface 42) in the air flow direction. Then, the tissue paper P can capture dust prior to the breathable mesh of the rotating filter 37 and the fixed filter 35 (opposing surface 42). Thereby, since dust is captured by the tissue paper P prior to the breathable mesh, early clogging of the breathable mesh of the rotating filter 37 and the fixed filter 35 can be suppressed, and the dust trapping performance of these filters can be increased. Can be maintained.

Then, if the filter paper 21 is rotated to the open position (see FIG. 5) and the tissue paper P is discarded, the dust captured by the tissue paper P can be discarded together.
In each figure, the tissue paper P is indicated by a thick solid line or a broken line. In addition, the part (refer FIG. 5 etc.) shown with the broken line in the tissue paper P may show the wrinkles of the tissue paper P.

Next, opening and closing of the filter device 21 will be described with reference to the tissue paper P.
First, the filter device 21 is opened as shown in FIG. In this state, the rotating member 33 is in the normal position. In this state, the tissue paper P is attached to the filter device 21 so as to completely cover the inside of the first filter frame 24 (including the filter unit 31). At this time, in the tissue paper P, a portion facing the opposing surface 42 (fixed filter 35 and rotating filter 37) that continuously form a concave shape is recessed and placed on the opposing surface 42 so as to follow the concave shape.

In this state, the peripheral edge of the tissue paper P protrudes outside the first filter frame 24 over the entire area. Further, in this state, the tissue paper P (lower part in FIG. 5) is applied to all the protrusions 39 of the rotating member 33.
Next, the filter device 21 in the open position is rotated and begins to close. Therefore, the position of the case 20 may be fixed and the filter device 21 may be rotated, or the position of the filter device 21 may be fixed and the case 20 may be rotated. In short, the filter device 21 may be rotated relative to the case 20 (the same applies to all cases where the filter device 21 is rotated from the open position hereinafter).

FIG. 6 is a right sectional view of the dust collecting container 10 at a position different from that in FIG. 4 and shows a state immediately before the filter device 21 is completely closed.
When the filter device 21 is rotated and the filter device 21 is in a state immediately before the filter device 21 is completely closed (immediately before the closed position) as shown in FIG. 6, the left and right guide shafts 40 of the rotation member 33 on the filter device 21 side are moved. The inner surface of the case 20 is in contact with one end (the upper end in FIG. 6) of the guide rail 19 on the same side in the width direction.

FIG. 7 shows a state in which the filter device 21 is completely closed in FIG.
When the filter device 21 is further rotated and completely closed to the closed position as shown in FIG. 7, each guide shaft 40 gets over one end of the corresponding guide rail 19 and fits into this one end. It is disposed between one end of the guide rail 19 and the inner surface of the case 20.
At this time, since the hook 28 on the case 20 side engages with the hook receiver 29 on the filter device 21 side as described above, the filter device 21 is closed and maintained in the closed position (see FIG. 4).

  At this time, as described above, the peripheral portion of the tissue paper P that has protruded outside the first filter frame 24 extends over the entire peripheral portion of the first filter frame 24 and the open side of the case 20. (Right side in FIG. 7). Thereby, the tissue paper P is positioned so as not to be displaced in a state along the suction port 22 side of the case 20 with respect to the fixed filter 35 and the rotation filter 37 (opposing surface 42).

  In this state, as described above, the tissue paper P is disposed on the upstream side of the rotating filter 37 and the stationary filter 35 (opposing surface 42) in the air flow direction (see the thick broken line arrow in FIG. 2). Therefore, when the dust collector 10 in this (completed) state is mounted on the vacuum cleaner main body 2 and the vacuum cleaner main body 2 is operated (see FIG. 2), the tissue paper P mainly captures dust, and the tissue paper In P, dust adheres to the side surface on the suction port 22 side. Here, since the tissue paper P has a concave shape along the facing surface 42, the tissue paper P can reliably collect the captured dust.

  The amount of dust adhering to the tissue paper P can be grasped by seeing through the inside of the case 20 through the water. Since a lot of dust adheres to the tissue paper P, if it is time to replace the tissue paper P with a new one, the dust collecting container 10 is detached from the electric vacuum cleaner main body 2 (see FIG. 2) and the filter device 21 is opened. (Rotate from the closed position to the open position). Therefore, the position of the case 20 may be fixed and the filter device 21 may be rotated, or the position of the filter device 21 may be fixed and the case 20 may be rotated (hereinafter, the filter device 21 is opened). The same applies in all cases).

FIG. 8 shows a state in which the filter device 21 starts to be opened in FIG.
When the filter device 21 is opened as shown in FIG. 8, the gap between the case 20 and the filter device 21 starts to expand from the upper region in FIG. 8. Accordingly, the peripheral edge of the tissue paper P is not sandwiched between the peripheral edge of the first filter frame 24 and the rear peripheral edge of the case 20.

  At this time, each guide shaft 40 that has been between one end portion of the guide rail 19 (upper end portion in FIG. 8) and the inner surface of the case 20 (fitted to one end portion of the guide rail 19) until now is attached to the case 20. In a state of being pulled and fitted to (engaged with) the guide rail 19, it moves along the guide rail 19 to the other end (lower end in FIG. 8) side. Along with this, the rotation member 33 that has been in the normal position until now rotates about the connecting shaft 34 and moves toward the rotation position described above.

At this time, the rotation filter 37 of the rotation member 33 rotates so as to approach the fixed filter 35. Then, the portion of the tissue paper P that has been applied to the rotating member 33 (the rotating filter 37) tends to approach the portion of the tissue paper P that has been applied to the fixed filter 35. Thereby, the tissue paper P tends to be deformed into a bag shape.
FIG. 9 shows a state where the filter device 21 is further opened in FIG. FIG. 10 is a right sectional view of the dust collecting container 10 at a position different from that in FIG. 9 and shows the same state as FIG.

  As shown in FIG. 9, when the filter device 21 is further opened toward the open position and each guide shaft 40 reaches the other end (the lower end in FIG. 9) of the guide rail 19, the rotation member 33 is moved to the rotation position. To reach. At this time, as shown in FIG. 10, the rotating filter 37 and the fixed filter 35 face each other, and the water droplet-shaped space C described above is partitioned by these filters, and the tissue paper P has an outline of the space C. It becomes a bag shape along. At this time, in the tissue paper P having a bag shape, the surface to which the dust T is attached comes to the inside of the bag, so that the dust T captured by the tissue paper P accumulates inside the bag of the tissue paper P.

Here, as described above, if the filter device 21 is rotated from the closed position to the open position, the rotation filter 37 is rotated so as to approach the fixed filter 35 in conjunction with this, thereby the filter device 21. The tissue paper P on the opposed surface 42 of 21 can be automatically folded into a bag shape, which is easy to use.
Further, as described above, since the tissue paper P placed on the facing surface 42 is recessed along the facing surface 42 (see FIG. 7), the rotating member 33 (the rotating filter 37) is a fixed filter. When the tissue paper P is rotated to the rotation position so as to approach 35, the tissue paper P tends to be in a bag shape.

Further, when the rotation member 33 reaches the rotation position, each protrusion 39 on the rotation member 33 side is fitted into the corresponding through hole 41 of the one side peripheral edge portion 32A of the support frame 32 provided with the fixed filter 35. In other words, the through holes 41 are engaged with the corresponding protrusions 39 when the rotation member 33 (the rotation filter 37) rotates so as to approach the fixed filter 35.
For this reason, in the tissue paper P, the portion that has been applied to each protrusion 39 and the portion that has been applied to the through hole 41 are pushed into the through hole 41 by the protrusion 39 in an overlapping state, and are thereby bound together. Here, the respective portions of the tissue paper P that have been applied to the protrusions 39 and the through-holes 41 are peripheral portions located toward the mouth of the tissue paper P bag. The mouth of P bag is bound.

  Since the peripheral edges of the tissue paper P are bound together in this way, the dust T collected inside the tissue paper P bag does not spill out of the tissue paper P bag. Such binding of the tissue paper P is sometimes referred to as a paper stapler. The protrusion 39 may be provided on the one side peripheral edge portion 32 </ b> A of the support frame 32, and the through hole 41 may be provided on the rotating member 33.

FIG. 11 shows a state in which the filter device 21 is completely opened in FIG.
When the filter device 21 is further opened from this state, the filter device 21 is completely opened to reach the open position as shown in FIG. At this time, each guide shaft 40 (see FIG. 9) is disengaged from the other end portion (right end portion in FIG. 11) of the guide rail 19 and is not engaged with the case 20 side. Thereby, the rotation member 33 (rotation filter 37) having the guide shaft 40 can return to the original position (the normal position away from the fixed filter 35) when the filter device 21 is in the closed position.

  Actually, as the guide shaft 40 is disengaged from the other end of the guide rail 19, the rotation member 33 having the guide shaft 40 rotates the rotation filter 37 in the direction away from the fixed filter 35. The first urging member (not shown) is urged to return to the normal position with certainty. Thereby, the fixed filter 35 and the rotation filter 37 (opposing surface 42) continuously form a concave shape again, and the bag of tissue paper P is disposed in the concave shape.

Therefore, if the tissue paper P bag is picked by hand and dropped into the trash box, or the dust container 10 is tilted to drop the tissue paper P bag into the trash box, the dust T captured by the tissue paper P is thrown into the trash box. be able to.
Referring to FIG. 10, in this way, the rotation filter 37 is rotated according to the rotation of the filter device 21 from the closed position to the open position (may be an intermediate position until reaching the open position). It rotates so that it may approach the fixed filter 35, and the tissue paper P on the opposing surface 42 is folded in a bag shape. Therefore, the dust T captured by the tissue paper P is discarded in a state where the dust T is collected inside the bag of the tissue paper P when the garbage is discarded, so that the dust T can be prevented from rising from the tissue paper P.

  Further, if the bundle of protrusions 39 and through holes 41 is a binding portion 43, the binding portion 43 is folded into a bag shape by the rotation filter 37 when the rotation filter 37 is rotated so as to approach the fixed filter 35. The peripheral edge of the tissue paper P is sandwiched between the protrusion 39 and the through hole 41 (strictly speaking, the peripheral edge of the through hole 41 in the one side peripheral edge 32A of the support frame 32).

As a result, the dust T accumulated in the tissue paper P bag is confined in the tissue paper P bag, so that the dust T can be reliably prevented from rising from the tissue paper P.
(2) Second Example Next, a dust collection container 10 according to a second example will be described. In the second example, the same members as those described in the first example are denoted by the same reference numerals, and the description of the overlapping parts in each member is omitted.

FIG. 12 is a perspective view of the dust collecting container 10 according to the second example of the present invention as viewed from the upper left front. FIG. 13 is a perspective view showing a state in which the filter device 21 is rotated away from the case 20 in the dust collecting container 10. FIG. 14 shows a state in which the flow path member 60 is rotated to the case 20 side in FIG.
Referring to FIG. 12, in the dust collection container 10 according to the second example, the case 20 has a box shape that narrows toward the front side.

  Further, the guide rail 19 (see FIG. 5) described above is not provided on the inner surface of the case 20, and instead, as shown in FIG. 13, three pressers are provided in the region between the suction port 22 and the handle 23 on the inner surface. Each pressing rib 51 with which the rib 51 is integrally provided has a substantially J shape when viewed from the right side in FIG. 13 and protrudes from the inner surface of the case 20 toward the inner side of the case 20. The three pressing ribs 51 are arranged at a predetermined interval in the width direction.

An L-shaped rib 52 having a substantially L-shaped block shape is integrally provided on the peripheral portion on the back side opened in the case 20. Two L-shaped ribs 52 are provided so as to form a pair on the left and right sides, and protrude from the outer peripheral edge on the back side of the case 20 to the outside.
13, the left L-shaped rib 52 extends linearly along the left peripheral edge on the back side of the case 20, and the left outer peripheral edge and the upper (handle 23 side) peripheral edge on the back side of the case 20. It bends to the right along the corner with the part and extends linearly along this upper peripheral edge to a position in front of the handle 23. Further, on the basis of the state of FIG. 13, the right L-shaped rib 52 extends linearly along the right peripheral edge on the back side of the case 20, and the right peripheral edge and the upper peripheral edge on the back side of the case 20. It bends to the left along the corner and extends linearly along this upper peripheral edge to a position just before the handle 23. Each L-shaped rib 52 is not provided at the peripheral edge portion on the hinge 26 side on the back side of the case 20.

A plurality of columnar protrusions 53 (engaged portions) projecting to the back side are provided on the side surfaces of the L-shaped ribs 52 exposed on the back side of the case 20. These protrusions 53 are arranged at a predetermined interval, and have a substantially L shape along the L-shaped rib 52 in a state of being gathered as a whole.
The case 20 is provided with a resin ring cutter 54 (first cut member). The ring cutter 54 has an annular shape slightly smaller than the suction port 22 and has a predetermined thickness in the axial direction thereof. The ring cutter 54 is inserted through the suction port 22 so that the outer peripheral surface thereof is along the suction port 22. In this state, the ring cutter 54 moves to a first position protruding from the suction port 22 to the outside (front side) of the case 20 and a second position protruding from the suction port 22 to the inside (back side) of the case 20. It is supported by the case 20 so as to be possible (to be able to rotate around the shaft 68 on the hinge 26 side in the front-packed manner). In FIG. 13, the ring cutter 54 in the second position is shown. Here, the ring cutter 54 is always urged so as to be positioned at the first position by a spring 67 (see FIG. 16B).

In the filter device 21, L-shaped ribs 55 having a substantially L-shaped thin plate shape are integrally provided on a peripheral portion of the first filter frame 24 (mesh filter 57 described later) on the case 20 side. Two L-shaped ribs 55 are provided so as to form a pair on the left and right sides and protrude outward from the peripheral edge (on the case 20 side) of the first filter frame 24.
13, the left L-shaped rib 55 extends linearly along the left peripheral edge of the first filter frame 24, and the left peripheral edge of the first filter frame 24 and the front side (hook receiver 29 side). ) It bends to the right along the corner with the peripheral edge and extends linearly along the front peripheral edge to a position in front of the hook receiver 29. Further, on the basis of the state of FIG. 13, the right L-shaped rib 55 extends linearly along the right peripheral edge of the first filter frame 24, and the right peripheral edge and the front peripheral edge of the first filter frame 24. It bends to the left along this corner and extends linearly along this labor side peripheral edge to a position in front of the hook receiver 29. Each L-shaped rib 55 is not provided on the outer peripheral edge of the first filter frame 24 on the hinge 26 side.

Each L-shaped rib 55 is provided with a plurality of round through-holes 56 (engaging portions) that penetrate the L-shaped rib 55 in the thickness direction. These through-holes 56 are arranged at a predetermined interval, and are substantially L-shaped along the L-shaped rib 55 in a state of being gathered as a whole.
In the second example, when the filter device 21 is closed and disposed in the closed position, the left L-shaped rib 55 contacts the left L-shaped rib 52 in the case 20 over the entire area, and the right L-shaped rib. 55 contacts the L-shaped rib 52 on the right side over the entire area. At this time, the corresponding protrusion 53 of the L-shaped rib 52 is fitted into the through hole 56 of the L-shaped rib 55 (not shown). That is, the protrusion 53 is engaged with the through hole 56 when the filter device 21 is rotated to the closed position.

  In the second example, the first filter frame 24 is provided with a fine mesh filter 57 (see a portion filled with dots). The mesh filter 57 is formed of a breathable mesh and closes the inner region of the frame-shaped first filter frame 24 over the entire area. The mesh filter 57 forms a facing surface that faces the other surface side (back side) of the case 20 in the filter device 21 in the closed position described above.

  Specifically, the mesh filter 57 is three-dimensionally formed by the main surface 58 and the side surface 59. The main surface 58 is a substantially trapezoidal inclined surface connected to the front side (hook receiver 29 side) periphery of the first filter frame 24 while being widened toward the front side (lower right side) in FIG. The side surface 59 rises from each of the left end, the right end, and the lower end (end on the hinge 26 side in FIG. 13) of the main surface 58 in the crossing direction of the main surface 58 and excludes the peripheral edge of the first filter frame 24 (excluding the front peripheral edge described above). ) Is an inclined surface connected to.

Due to the main surface 58 and the side surface 59, the mesh filter 57 is depressed toward the lower side (the downstream side in the air flow direction described above, see the thick broken line arrow in FIG. 2), and in FIG. Dust removal shape that becomes wider and shallower. Therefore, the mesh filter 57 can reliably collect the captured dust.
Here, the first filter frame 24 is provided with a plurality of resin-made elongate beam members 62, and these beam members 62 are arranged in the inner region of the frame-shaped first filter frame 24. . In the first filter frame 24, the beam member 62 holds the mesh filter 57, whereby the above-described dust removal shape of the mesh filter 57 is maintained.

The first filter frame 24 is provided with a flow path member 60. The flow path member 60 has a tubular shape that is bent so as to form a substantially J-shape when viewed from the right side. The cross section of the flow path member 60 has a substantially D shape having an arc portion at the center of curvature of the bent flow path member 60.
The channel member 60 has an inlet 60A at one end on the hinge 26 side, and an outlet 60B at the other end on the opposite side. The inlet 60A and the outlet 60B communicate with the channel member 60. .

Further, on the inlet 60A side of the flow path member 60, a substantially U-shaped flange 61 (second pressing portion) that borders the inlet 60A is integrally provided. The collar portion 61 is a flat plate shape and is formed of a soft material such as rubber. On the other hand, a portion that borders the outlet 60B on the outlet 60B side of the flow path member 60 is referred to as an outlet portion 64 (first pressing portion).
A support shaft 65 extending in the width direction is provided on the inner peripheral edge of the first filter frame 24 in the vicinity of the hinge 26 (see FIG. 14), and this support shaft 65 is provided at a portion of the flow path member 60 on the inlet 60A side. It is inserted. Thus, the flow path member 60 is supported by the first filter frame 24 (filter device 21) and is rotatable about the support shaft 65 (inlet 60A side). Specifically, the flow path member 60 is rotatable between a storage position shown in FIG. 13 and a floating position (see FIG. 14).

  The flow path member 60 in the storage position is stored inside the dust filter shape (recessed portion) of the mesh filter 57 inside the first filter frame 24, and is along the side surface 59 on the hinge 26 side of the mesh filter 57. At this time, the outlet portion 64 is in contact with the mesh filter 57, and the outlet 60 </ b> B faces the main surface 58 of the mesh filter 57. In FIG. 13, the outlet 60 </ b> B faces the main surface 58 from above. Further, in FIG. 13, the inlet 60 </ b> A faces upward, and the inlet 60 </ b> A is on the rotation locus of the ring cutter 54 when the case 20 is rotated.

  When the flow path member 60 in the storage position is rotated so that the outlet 60B (the outlet portion 64) is separated from the main surface 58, the flow path member 60 is lifted from the mesh filter 57 on the outlet portion 64 side, and more fully. When it rotates, it is placed at the floating position shown in FIG. At this time, the flow path member 60 completely protrudes from the inside of the first filter frame 24 and is positioned on the case 20 side. When the flow path member 60 is in the storage position, the outlet 60B facing the main surface 58 from above in FIG. 13 faces upward in FIG. 14 when the flow path member 60 is in the floating position. I have n’t met. Further, the outlet portion 64 floats from the mesh filter 57 and does not contact the mesh filter 57.

  Here, magnets 63 (second urging members) repelling each other are provided on each of the flow path member 60 and the portion on the hinge 26 side facing the flow path member 60 in the storage position in the first filter frame 24. Is provided. Therefore, as the magnets 63 are repelled, the flow path member 60 is always urged in the direction in which the outlet portion 64 moves away from the mesh filter 57 so as to go to the floating position.

  Then, as shown in FIG. 14, with the filter device 21 open (in the open position) and the flow path member 60 in the floating position, this time the filter device 21 is closed and placed in the closed position (described later). (See FIG. 18). Then, the flow path member 60 that has been in the floating position until now is brought into contact with a portion that borders the suction port 22 on the inner surface of the case 20, thereby rotating to the storage position against the repulsive force of the magnet 63 described above. Move (see FIG. 19B). At this time, in the flow path member 60, the inlet 60A communicates with the ring cutter 54 and the suction port 22 (see FIG. 19B).

In this state, as shown in FIG. 14, when the filter device 21 is rotated and opened from the closed position toward the open position, the flow path member 60 is separated from the inner surface of the case 20 and contacts the case 20. Therefore, it is rotated to the floating position side by being biased by the repulsive force between the magnets 63 described above.
In the dust container 10 of the second example, the air flowing in from the suction port 22 passes through the mesh filter 57 of the first filter frame 24 and then the pleated filter 50 of the second filter frame 25 (see FIG. 2). The mesh filter 57 is easily clogged with dust contained in the air.

Therefore, similarly to the first example, in the second example, tissue paper can be set on the upstream side of the mesh filter 57 in the air flow direction (see the thick broken line arrow in FIG. 2) in the dust collecting container 10. It has become.
Next, a procedure for setting and removing a tissue paper will be described.
First, the filter device 21 is opened as shown in FIG. Then, the flow path member 60 rises from the storage position to the floating position side. In addition, at this time, the flow path member 60 should just float from the accommodation position (mesh filter 57), and does not necessarily need to be arrange | positioned in a floating position.

Next, the tissue paper P is set on the mesh filter 57 from above (from the case 20 side) with the posture of FIG. 14 as a reference.
FIG. 15 shows a state where the flow path member 60 is pressing the tissue paper P in FIG. 16A is a front view of the dust collecting container 10 in a state where the filter device 21 is closed in FIG. 15, and FIG. 16B is a cross-sectional view taken along line AA in FIG.

  Regarding the setting (attachment) of the tissue paper P, referring to FIG. 15, the portion on the hinge 26 side of the tissue paper P enters the gap between the flow path member 60 floating from the mesh filter 57 and the mesh filter 57. To. In addition, the peripheral edge of the tissue paper P excluding the hinge 26 side protrudes from the left and right L-shaped ribs 55 (see FIG. 13) of the first filter frame 24.

The tissue paper P set in this way covers the mesh filter 57 over the entire area. The portion of the tissue paper P that covers the mesh filter 57 is recessed along the dust filter shape (recessed portion) of the mesh filter 57.
When the filter device 21 is closed in this state, as shown in FIG. 16A, the peripheral edge portion of the tissue paper P protruding outside the first filter frame 24 extends over the entire area (excluding the hinge 26 side). The left and right L-shaped ribs 55 (see FIG. 13) on the first filter frame 24 side and the left and right L-shaped ribs 52 on the case 20 side are sandwiched.

  Thereby, the tissue paper P is positioned so as not to be displaced in a state where the tissue paper P is depressed along the dust-collecting shape of the mesh filter 57 (see FIG. 15). As described above, at this time, since the protrusion 53 of the L-shaped rib 52 is fitted into the through-hole 56 of the L-shaped rib 55 (see FIG. 13), the peripheral edge of the tissue paper P is in contact with the through-hole 56. The portion is pushed into the through hole 56 by the protrusion 53 (not shown). Therefore, the tissue paper P is firmly positioned.

Further, as shown in FIG. 16B, when the filter device 21 is closed, the flow path member 60 is disposed at the storage position. At that time, the outlet portion 64 is attached to the mesh filter 57 in the flow path member 60. The tissue paper P is pressed against the mesh filter 57. This also positions the tissue paper P.
In this state, the tissue paper P is arranged on the upstream side of the mesh filter 57 in the air flow direction (see the thick broken line arrow in FIG. 2). Therefore, when the dust collector 10 in this (completed) state is mounted on the vacuum cleaner main body 2 and the vacuum cleaner main body 2 is operated (see FIG. 2), the tissue paper P mainly captures dust, and the tissue paper In P, dust accumulates in a portion recessed along the mesh filter 57.

  Thereby, since the tissue paper P can capture dust prior to the breathable mesh of the mesh filter 57, early clogging of the breathable mesh can be suppressed. In addition, since the tissue paper P attached to the mesh filter 57 has a shape that is recessed along the recessed portion of the mesh filter 57, the tissue paper P can reliably collect captured dust.

  Then, when the dust collecting container 10 is detached from the electric vacuum cleaner main body 2 (see FIG. 2) and the filter device 21 is opened as shown in FIG. 15, the tissue paper P is sandwiched between the L-shaped rib 55 and the L-shaped rib 52. In addition, it is not pressed against the mesh filter 57 by the flow path member 60 floating from the normal position. Thereby, the positioning of the tissue paper P is released. Therefore, when the dust collecting container 10 is tilted in this state, the tissue paper P that captures the dust can be dropped together with the dust into the trash box and discarded.

However, in this case, when the filter device 21 is opened, there is a risk that dust accumulated in the depression of the tissue paper P will be scattered by the bounce.
Therefore, in the second example, the use of two tissue papers prevents the dust captured by the tissue papers from being scattered. Here, the sign of the first tissue paper along the mesh filter 57 is P, and the sign of the second another tissue paper is marked Q, so that the two tissue papers are distinguished.

In this case, first, as shown in FIG. 15, the first tissue paper P is set (attached) along the recessed portion of the mesh filter 57 by the procedure described above.
FIG. 17 shows a state in which another tissue paper Q is placed on the flow path member 60 in FIG.
Next, as shown in FIG. 17, the second tissue paper Q is set so as to cover the entire flow path member 60. At this time, the portion on the hinge 26 side of the tissue paper Q is configured to block almost the entire area of the inlet 60 </ b> A of the flow path member 60. Further, the peripheral edge of the tissue paper Q excluding the hinge 26 side is overlapped with the peripheral edge of the tissue paper P excluding the hinge 26 side over almost the entire region.

At this time, in the tissue paper Q, the portion on the hinge 26 side is received by the flange 61 of the flow path member 60, and the tissue paper P flows between the portion of the tissue paper P that is recessed along the mesh filter 57 and the tissue paper Q. A space D in which the road member 60 is disposed is formed.
FIG. 18 shows a state in which the filter device 21 is closed in FIG. 19, (a) is a front view of the dust collecting container 10 in the state of FIG. 18, and (b) is a cross-sectional view taken along the line BB of (a).

  And the filter apparatus 21 is closed and arrange | positioned in a closed position. Then, as shown in FIG. 18, the peripheral edges of the tissue papers P and Q that have protruded outside the first filter frame 24 (see FIG. 13) extend over the entire region (excluding the hinge 26 side). It is sandwiched between the left and right L-shaped ribs 55 (see FIG. 13) on the one filter frame 24 side and the left and right L-shaped ribs 52 on the case 20 side.

  Further, as shown in FIG. 19B, the entire area of the portion (see FIG. 17) of the tissue paper Q that is received (hangs) by the flange 61 of the flow path member 60 at the storage position is as shown in FIG. Is pressed against the inner surface of the case 20. Further, the outlet portion 64 of the flow path member 60 at the storage position presses the tissue paper P attached to the mesh filter 57 against the mesh filter 57.

  As described above, the tissue papers P and Q are positioned so as not to be displaced in the state where the space D described above is formed. In this state, the flow path member 60 is disposed between the tissue paper P and another tissue paper Q, and the flow path member 60 is disposed between the two tissue papers P and Q. A bag having an internal space D is formed. At this time, since the flow path member 60 presses the tissue paper bag H against the mesh filter 57 and the inner surface of the case 20, the tissue paper bag H is positioned while maintaining the bag shape.

  At this time, as described above, since the protrusion 53 of the L-shaped rib 52 is fitted into the through-hole 56 of the L-shaped rib 55 (see FIG. 13), the through-hole is formed at the peripheral edge of the tissue paper P and Q that overlap each other. The portion in contact with 56 is pushed into the through hole 56 by the protrusion 53 (not shown). Therefore, the tissue papers P and Q are firmly positioned.

  Further, the peripheral edges (excluding the hinge 26 side) of the tissue papers P and Q that are overlapped with each other are bound (paper stapled) by being pushed into the through holes 56 by the respective protrusions 53. Here, when the bundle of the protrusion 53 and the through hole 56 is a binding portion 66 (see FIG. 13), the binding portion 66 overlaps the tissue papers P and Q when the filter device 21 is rotated to the closed position. The peripheral edge is sandwiched between the protrusion 53 and the through hole 56 (strictly speaking, the peripheral edge of the through hole 56 in the L-shaped rib 55, see FIG. 13).

By binding in this way, the above-described bag H is completed by the tissue papers P and Q, and the tissue papers P and Q are not separated. The protrusion 53 may be provided on the L-shaped rib 55 on the filter device 21 side, and the through hole 56 may be provided on the L-shaped rib 52 on the case 20 side (see FIG. 13).
At this time, the holding rib 51 provided on the inner surface of the case 20 faces the inner surface of the case 20 on the handle 23 side in the second tissue paper Q received by the flange portion 61 of the flow path member 60. The pressed portion is pressed away from the inner surface of the case 20. Thereby, a space E having a thickness equivalent to the pressing rib 51 is secured between the inner surface of the case 20 where the pressing rib 51 is provided and the tissue paper Q. The space E is connected to the mesh filter 57.

Thus, the setting of the two tissue papers P and Q is completed, and the dust collecting container 10 is completed. At this time, the ring cutter 54 of the case 20 is in the first position and protrudes from the suction port 22 to the outside (front side) of the case 20.
Next, the dust collecting container 10 completed in this way is attached to the vacuum cleaner main body 2 (see FIG. 2).
FIG. 20 is a right side sectional view of the electric vacuum cleaner main body 2 and shows a state where the dust container 10 in the state of FIG. 19B is being attached to the electric vacuum cleaner main body 2. FIG. 21 shows a state where the dust container 10 is attached to the electric vacuum cleaner main body 2 in FIG.

Referring to FIG. 20, as described above, dust container 10 can be attached to vacuum cleaner body 2 from above by opening the front side portion of top surface 2A of vacuum cleaner body 2. Therefore, first, the dust collecting container 10 is disposed right above the opened front portion of the top surface 2A, and then lowered (see the thick arrow).
Here, the upper end of the front wall 2 </ b> B of the electric vacuum cleaner main body 2 is located directly below the ring cutter 54 in the first position. Therefore, when the dust collecting container 10 is lowered as it is, the front end edge of the ring cutter 54 at the first position comes into contact with the upper end portion of the front wall 2B from above, and accordingly, the rear side (second position side). Start moving to. Here, since the front end edge of the ring cutter 54 at the first position is inclined to the front upper side when viewed from the width direction, when the upper end portion of the front wall 2B contacts the front end edge of the ring cutter 54, the contact force Effectively acts on the ring cutter 54 to the rear side. Therefore, the ring cutter 54 slides smoothly to the rear side.

Then, as shown in FIG. 21, when the lowering of the dust collecting container 10 is completed and the dust collecting container 10 is completely attached to the electric vacuum cleaner body 2, the ring cutter 54 reaches the second position. . At this time, the front wall 2B of the vacuum cleaner body 2 is in contact with the ring cutter 54 from the front, and the ring cutter 54 is held in the second position.
Here, when the ring cutter 54 moves rearward from the first position toward the second position, the ring cutter 54 protrudes from the suction port 22 to the inside of the case 20 as described above, so that the flow path member 60 It is inserted through the inlet 60A. Thereby, the inside of the ring cutter 54 (in other words, the suction port 22) communicates with the inside of the flow path member 60.

  Then, when the ring cutter 54 is inserted into the inlet 60A, the ring cutter 54 is a portion R of the tissue paper Q that is applied to the inlet 60A (as received by the flange portion 61 of the flow path member 60) as described above. Is cut from other parts. As a result, the inlet 60A is not blocked by the tissue paper Q, so that dust and air taken into the case 20 from the suction port 22 can be smoothly passed through the flow path member 60 from the inlet 60A as will be described later. It can be allowed to flow into the tissue paper bag H.

Here, since the collar portion 61 on the inlet 60A side presses the tissue paper Q that is being received against the inner surface of the case 20, the position of the portion R that covers the inlet 60A in the tissue paper Q is stable. The ring cutter 54 can cut the portion R smoothly.
In particular, since the collar portion 61 is formed of a soft material, the received tissue paper Q is brought into close contact with the inner surface of the case 20, so that the portion R of the tissue paper Q that covers the inlet 60 </ b> A is less likely to be displaced (鍔Therefore, the ring cutter 54 can cut the portion R smoothly. The cut portion R is accommodated in the space D between the tissue paper P and Q described above.

In this state, the vacuum cleaner body 2 (see FIG. 2) can be operated.
FIG. 22 is a right side cross-sectional view of the dust collecting container 10 during operation of the electric vacuum cleaner main body 2.
When the electric vacuum cleaner main body 2 is operated, as indicated by broken line arrows in FIG. 22, the air and dust T sucked into the electric vacuum cleaner main body 2 are discharged from the suction port 22 (ring cutter 54) to the dust collecting container 10. It is taken into the case 20. The dust T thus taken into the case 20 enters the flow path member 60 from the inlet 60A and then flows into the tissue paper bag H (the space D between the tissue papers P and Q) from the outlet 60B. At this time, it is captured by the tissue paper P or Q and collected in the tissue paper bag H.

  Here, the collar portion 61 formed of a soft material in the flow path member 60 presses the tissue paper Q against the inner surface of the case 20 without any gap (adheres it). This prevents the dust T and air taken into the case 20 from the suction port 22 from escaping into the gap between the inner surface of the case 20 and the tissue paper Q, and ensures that these dust T and air are reliably discharged from the inlet 60A. It can pass through the flow path member 60 and flow into the tissue paper bag H.

  In FIG. 22, the flow of air flowing into the internal space D of the bag H is indicated by three dashed arrows, and the air indicated by the lowest dashed arrow flows to the mesh filter 57 on the side surface 59 on the hinge 26 side. The tissue paper P in the portion along the side and the side surface 59 pass in this order, and then pass through the pleated filter 50 toward the electric blower 11 (see FIG. 2).

On the other hand, the air shown by the broken line arrow between the uppermost broken line arrow and the lowermost broken line arrow causes the tissue paper P in the main surface 58 along the mesh filter 57 and the main surface 58 to be It passes in order, and then passes through the pleated filter 50 toward the electric blower 11 (see FIG. 2).
Then, the air indicated by the uppermost broken line arrow rises in FIG. 22, passes through the portion of the tissue paper Q that is pressed by the pressing rib 51, flows into the space E described above, and then the main surface 58 ( After passing through the mesh filter 57), it passes through the pleated filter 50 and goes to the electric blower 11 (see FIG. 2).

As a result, the air that has flowed into the tissue paper bag H passes through the tissue paper P and passes through the tissue E after passing through another tissue paper Q as well as the first flow path toward the mesh filter 57. A second flow path toward the mesh filter 57 can also flow therethrough.
Therefore, not only the tissue paper P but also another tissue paper Q can capture the dust on the flowing air, so that the efficiency of capturing dust by the tissue paper P and Q can be improved. In particular, in this case, since the area of the tissue paper through which the dust passes is approximately doubled, it is possible to capture about twice as much dust at a time as compared with the case of capturing the dust with the tissue paper P alone. . Since the air can flow smoothly in the dust collecting container 10 accordingly, the suction amount of dust can be increased while maintaining the suction force described above.

The dust T thus captured by the tissue papers P and Q accumulates in the bag H (the space D described above) constituted by the tissue papers P and Q.
Next, a procedure for discarding the dust T collected in the bag H will be described.
FIG. 23 shows a state in which the filter device 21 is rotated away from the case 20 in the dust collecting container 10 in which dust is accumulated. 24 is a left sectional view of the dust collecting container 10 in FIG. FIG. 25 shows a state in which the dust T is discarded from the dust collecting container 10 in FIG. FIG. 26 is a perspective view of the dust collecting container 10 in the state of FIG.

First, the filter device 21 is opened as shown in FIG. At this time, when the filter device 21 is positioned below the case 20 and the handle 23 of the case 20 is grasped and the button 27 is pressed, the filter device 21 rotates away from the case 20 downward. Open.
At the moment when the filter device 21 is opened, as shown in FIG. 24, the portion on the hinge 26 side of the tissue paper P constituting the bag H is pressed against the mesh filter 57 by the outlet portion 64 of the flow path member 60 in the storage position. It has been.

  However, immediately after opening the filter device 21, as shown in FIG. 25, the flow path member 60 is quickly rotated toward the floating position by the repulsive force between the two magnets 63 described above. The outlet portion 64 of the member 60 does not press the tissue paper P attached to the mesh filter 57 against the mesh filter 57. Further, when the filter device 21 is in the open position, the flow path member 60 on the filter device 21 side is separated from the inner surface of the case 20, so that the collar portion 61 does not press the tissue paper Q against the inner surface of the case 20.

As a result, the bag H made of the two tissue papers P and Q is not positioned in the dust collecting container 10, so that the tissue paper bag H in which the dust T is accumulated is collected by its own weight with reference to FIG. It can be dropped from the dust container 10 and thrown away into the trash bin.
Here, the dust T trapped in the tissue paper P or Q is discarded in a state where the dust T is collected in the tissue paper bag H when the garbage is thrown away, so that the dust T is prevented from rising from the tissue paper P or Q. it can.

As described above, when the filter device 21 is rotated to the closed position (see FIGS. 18 and 19), the binding portion 66 (see FIG. 13) is separated from the peripheral portion of the tissue paper P and another tissue paper Q. Bind with the peripheral edge. Here, a reference numeral 78 is attached to the joint between the peripheral edge of the tissue paper P and the peripheral edge of the tissue paper Q.
By binding in this way, the dust accumulated inside the bag H by these two tissue papers P and Q is trapped inside the bag H, so that it is ensured that the dust T rises from the tissue paper P or Q. Can be prevented.
(3) Third Example Finally, a dust collection container 10 according to a third example will be described. Note that in the third example, the same members as those described in the first and second examples are denoted by the same reference numerals, and description of overlapping portions in each member is omitted.

FIG. 27 is a perspective view of the dust collecting container 10 according to the third example of the present invention as seen from the upper right front.
Referring to FIG. 27, in the dust collecting container 10 according to the third example, the case 20 has a box shape that narrows toward the front side. However, since the case 20 is thin in the front-rear direction, the case 20 is recessed toward the front side rather than the box shape. It can be said to be a dish shape (see also FIG. 28 described later).
FIG. 28 is a perspective view showing a state in which the filter device 21 is rotated away from the case 20 in the dust container 10.

Referring to FIG. 28, at the peripheral portion on the back side opened in case 20, plate-like protruding portions 70 that protrude outward are integrally formed on the peripheral portions on the left side, right side, handle 23 side, and hinge 26 side. Provided. On the back side of each protrusion 70, a protrusion 71 (engaged portion) that protrudes toward the back is integrally provided.
Further, an annular cut portion 72 (second cut member) is integrally provided on the inner surface of the case 20 so as to project the suction port 22 toward the back surface side. The peripheral wall of the cut portion 72 has a conical shape that becomes narrower toward the back side.

  In the third example, the first filter frame 24 is divided into two parts on the case 20 side and the second filter frame 25 side. In addition, a facing surface 80 that is recessed toward the downstream side in the air flow direction is provided inside the first filter frame 24 having a substantially quadrangular frame shape. Here, the facing surface 80 is a surface partitioned by the pleated filter 50, but may be formed of a breathable mesh as in the second example. The facing surface 80 faces the opened back side of the case 20 when the filter device 21 is in the closed position. The opposing surface 80 that is recessed in this way can reliably collect the captured dust.

Then, in the first filter frame 24, at the peripheral portion on the case 20 side (in other words, the peripheral portion of the facing surface 80), a plate-like protrusion that protrudes outward at the peripheral portion on the left side, the right side, and the hinge 26 side. The part 73 is provided integrally. Each projection 73 is formed with a through hole 74 (engagement portion) that penetrates the projection 73 in the thickness direction.
In the first filter frame 24, the basket portion 75 is disposed inside the portion on the case 20 side (that is, the recessed portion of the facing surface 80 described above). The basket portion 75 is a resin basket having a large opening 76 on the case 20 side (position facing the back side of the case 20), and has a wide bathtub shape (substantially rectangular parallelepiped shape) as a whole. The basket portion 75 fits almost exactly in the inner portion of the first filter frame 24 (specifically, the recessed portion of the facing surface 80). The protrusion 73 described above is integrally provided on the peripheral edge of the basket 75 that borders the opening 76 on the opposite side of the hinge 26. A through hole 74 is also formed in the protruding portion 73. The protrusion 73 (through hole 74) may be provided only at the peripheral edge of the basket 75, or may be provided only at the peripheral edge of the facing surface 80 of the first filter frame 24. Further, the protrusion 71 may be provided on the filter device 21 side, and the through hole 74 may be provided on the case 20 side.

Here, when the filter device 21 is rotated to the closed position, the basket portion 75 is positioned between the back surface side of the case 20 and the facing surface 80, and the first filter frame 24 and the protruding portions 73 of the basket portion 75 are arranged. A corresponding protrusion 71 is fitted into the through hole 74 on the case 20 side. In other words, each protrusion 71 is engaged with the corresponding through hole 74.
In the third example, two tissue papers P and Q can be set as in the second example.

For this purpose, first, as shown in FIG. 28, the filter device 21 is opened, and the opening 76 of the basket portion 75 is directed upward.
FIG. 29 shows a state in which the tissue paper P is set in the basket portion 75 in the dust collecting container 10 in the state of FIG.
Next, as shown in FIG. 29, the first tissue paper P is set (attached) to the basket portion 75 along the inner surface of the basket portion 75. At this time, the tissue paper P follows the internal shape of the basket portion 75, and has a concave shape that is recessed downward in FIG. That is, the tissue paper P is three-dimensionally attached to the basket portion 75. Here, in the tissue paper P, the peripheral edge (end) protrudes from the opening 76 over the entire area.

FIG. 30 shows a state in which another tissue paper Q is additionally set in the basket portion 75 in the dust collecting container 10 in the state of FIG.
In this state, next, as shown in FIG. 30, the second tissue paper Q is mounted on the basket portion 75 so as to overlap the first tissue paper P. At this time, the peripheral edge of the tissue paper Q is overlapped with the peripheral edge of the tissue paper P over the entire area. Then, the tissue paper Q is flattened substantially horizontally as a whole, and the opening 76 of the basket portion 75 (in other words, the opening of the concave portion recessed downward in the tissue paper P) is in a state of being covered from above. .

Finally, the filter device 21 is rotated to the closed position and closed.
31, (a) is a front view of the dust collecting container 10 in a state where the filter device 21 is closed in FIG. 30, and (b) is a sectional view taken along the line CC of (a).
When the filter device 21 is closed as shown in FIG. 31, the peripheral edge portions of the tissue paper Q and the tissue paper P that overlap each other over the entire region are projected over the entire region, the first filter frame 24, and the basket portion 75. Between the projections 73 (see FIG. 28). At this time, the peripheral edge portions of the tissue paper Q and the tissue paper P that overlap each other are pushed into the through hole 74 (see FIG. 28) of the protrusion 73 by the protrusion 71 of the protrusion 70 and are bound together (paper) Stapled).

Here, if a group of the protrusion 71 and the through hole 74 is a binding portion 79 (see FIG. 28), the binding portion 79 overlaps the tissue papers P and Q when the filter device 21 is rotated to the closed position. The peripheral edge portion is sandwiched between the protrusion 71 and the through hole 74 (strictly speaking, the peripheral edge portion of the through hole 74 in the protruding portion 73).
As a result, referring to FIG. 31B, a bag H having a shape similar to the basket portion 75 is formed by the tissue paper Q and the tissue paper P. This bag H exists between the back side (inner surface) of the case 20 and the facing surface 80.

  Here, when the filter device 21 is closed and rotated from the open position to the closed position, the cut portion 72 of the case 20 pierces the portion of the tissue paper Q that covers the opening 76, and a hole 77 is formed in this portion. I can make it. Thereby, the suction port 22 communicates with the inside of the bag H through the hole 77. Therefore, as will be described later, the dust taken into the case 20 from the suction port 22 can be reliably stored in the tissue paper bag H by passing through the hole 77 formed by the cut portion 72.

  The dust container 10 with the filter device 21 in the closed position is attached to the vacuum cleaner body 2 (see FIG. 2), and the vacuum cleaner body 2 is operated. Then, the air sucked into the vacuum cleaner main body 2 flows into the tissue paper bag H from the suction port 22 through the hole 77 described above, and after passing through the tissue paper P, the pleat filter It goes to the electric blower 11 (refer FIG. 2) side through 50.

The dust contained in the air is captured by the tissue paper P of the bag H prior to the facing surface 80 and accumulates inside the bag H. Thereby, the early clogging of the filter device 21 (here, the pleated filter 50) on the facing surface 80 can be suppressed.
Next, a procedure for throwing away dust accumulated in the bag H will be described.
FIG. 32 is a perspective view showing a state in which the filter device 21 is rotated away from the case 20 in the dust collecting container 10 in the state of FIG. 31. FIG. 33 is a left sectional view of the dust collecting container 10 in the state of FIG. 32, and shows a state in which the dust T is discarded from the dust collecting container 10.

First, the filter device 21 is opened as shown in FIG. At this time, when the filter device 21 is positioned below the case 20 and the handle 23 of the case 20 is gripped and the button 27 (see FIG. 3) is pressed, the filter device 21 moves away from the case 20 downward. Rotate to open.
In this state, the bag H is fitted in the basket portion 75. When the filter device 21 is tilted as shown in FIG. 33, the bag H falls off the basket portion 75 due to its own weight. Therefore, if there is a trash box where the bag H falls, the tissue paper bag H packed with the dust T can be thrown into the trash box. In particular, the dust T captured by the tissue paper P is discarded in a state in which the dust T is collected in the tissue paper bag H when the garbage is discarded, so that the dust T can be prevented from rising from the tissue paper P or Q.

Here, as described above, when the filter device 21 is rotated to the closed position, the binding portion 79 (see FIG. 28) binds the peripheral portion of the tissue paper P and the peripheral portion of the tissue paper Q (FIG. 31). reference). Here, a reference numeral 78 is attached to the joint between the peripheral edge of the tissue paper P and the peripheral edge of the tissue paper Q (see FIG. 32).
By binding in this way, the dust T accumulated inside the bag H by these two pieces of tissue paper is confined in the bag H, so that the dust T can be reliably prevented from rising from the tissue paper P or Q. .

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