By the way, when throwing away the dust collected in the dust collecting case, it is desirable in terms of hygiene to throw away the dust without touching it as much as possible.
In the invention described in Patent Document 1, the storage part for collecting collected dust is formed in a dish shape, so that when the storage part is opened in an attempt to throw away the dust, the dust is abruptly moved without being leveled. Proposals have been made that it can be thrown away without spilling. However, since the collected dust is compressed to the flat bottom portion of the storage portion, there is a problem in that it is difficult to throw away the dust because the dust easily spreads outside when throwing away the dust.

  Further, in the invention described in Patent Document 1, it has been proposed that disposable dust collecting paper such as tissue paper is used in the storage part to easily discard dust, and the tissue paper is stored inside the dust collecting case. Tissue paper is attached by providing partition ribs that are pressed so as to follow the shape. However, the partition ribs are formed so as to sandwich the collected dust, and there is a problem that the dust is caught and difficult to drop when thrown away.

  In the invention described in Patent Document 2, it has been proposed that when the dust is thrown away, the dust container protrudes from the dust collecting case and is opened so that the dust container expands up and down or left and right, thereby easily discharging the dust. . However, since the deep dust container is configured to expand vertically or horizontally, there is a limit to the opening of the dust container when the dust is thrown away, and there is a risk that the dust will remain attached to the back part of the dust container. there were. There has also been a desire to improve usability when cleaning dust adhering to a deep dust container.

  Further, in the invention described in Patent Document 2, the dust container is reduced by using a disposable dust collecting filter paper such as tissue paper on the upstream side of the dust container as a collecting means for collecting dust. Proposals have been made. However, it is difficult to attach tissue paper or the like along the wall surface of the dust container with a depth, and when a space is formed between the wall surface of the dust container when attaching tissue paper or the like, the tissue paper is sucked when dust is sucked. There was also a risk of breaking.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a vacuum cleaner that is easy to throw away dust and is easy to use.
In addition, the present invention solves the above-mentioned conventional problems, and provides a vacuum cleaner that can easily dispose of dust and that can be suitably disposed with a disposable dust collecting filter paper for collecting means for collecting dust. The purpose is to do.

  The present invention relates to an electric vacuum cleaner having a dust collection case and a dust container that is provided in and out of the dust collection case, the dust container having a plurality of side walls, At least one side wall part of the side wall parts can be opened and closed with a side part of another adjacent side wall part as a fulcrum, and the dust container is provided so as to protrude from the opening of the dust collecting case, When projecting from the dust collection case, the side wall part that can be opened and closed opens with respect to the other side wall part, and the side wall part that can be opened and closed is stored in the dust collection case, so that the side wall part that can be opened and closed is the other side wall part. It is characterized by closing against.

  Further, the present invention provides a vacuum cleaner comprising a vacuum cleaner body and a dust collection case detachably attached to a dust collection chamber of the vacuum cleaner body, wherein the dust collection case is formed by a suction port and the suction port. A collecting means for collecting the dust sucked from the suction port, and having a three-dimensional shape that is recessed to the opposite side of the formed side, being openable and closable with respect to the dust collecting case, and the collecting means Protruding means that protrudes in a direction along the side wall portion in the vicinity of the side wall portion constituting the collecting means in a state of being closed with respect to the dust collecting case.

The operation level of the electric blower can be switched by operating a hand operation SW provided on the operation tube 4.
In the following description, the direction of each part is referred to based on the direction shown in FIG.

As shown in FIG. 2, an openable / closable lid 2 a is provided on the upper surface of the cleaner body 2. By opening the lid 2 a, the accommodation chamber 2 b in which the dust collecting case 10 is accommodated is exposed. It is like that. The dust collection case 10 is detachably attached to the storage chamber 2b, and is periodically taken out from the storage chamber 2b after cleaning or the like. And the dust collected inside the dust collection case 10 is thrown away to a trash box etc. The storage chamber 2 b is formed on the front side inside the cleaner body 2, and the electric blower is arranged on the rear side inside the cleaner body 2.
The lid 2a is opened when the dust collecting case 10 is taken in and out, and is closed during the cleaning operation. The attaching / detaching direction of the dust collecting case 10 with respect to the storage chamber 2b is substantially vertical.

As shown in FIG. 3, the dust collection case 10 includes a cylindrical case member 11 and a lid member 12 rotatably provided at the front portion of the case member 11, and inside the case member 11, A dust container 20 (see FIG. 4) that functions as a first filter that separates air and dust is provided. Further, a filter member 15 (see FIG. 4) is provided at the rear portion of the case member 11. The front opening (opening 11 b) of the case member 11 is closed by the lid member 12, and the rear opening of the case member 11 is closed by the filter member 15.
As shown in FIG. 5, the lid member 12 is rotatably provided around the hinge portion 11 a provided at the lower front end of the case member 11, and the lid opening release provided at the upper front portion of the case member 11 is provided. By operating the operation button 13 (see FIG. 3), the operation button 13 is rotated so as to fall forward, and the opening 11b of the case member 11 is opened. And the dust container 20 protrudes through the opening part 11b in the state by which the cover member 12 was opened. In addition, the rear side of the dust container 20 is located in the dust collecting case 10 in a state where the dust container 20 protrudes from the opening 11b. However, the rear side of the dust container 20 may be located outside the dust collection case 10 in a state where the dust container 20 protrudes from the opening 11b. That is, the entire dust container 20 may be located outside the dust collection case 10 with the dust container 20 protruding from the opening 11b. Further, the lid member 12 is provided so as to be rotatable around the hinge portion provided at the upper front end of the case member 11 instead of being provided around the hinge portion 11a provided at the lower front end of the case member 11. May be.
A circular inflow port (suction port) 12 a (see FIG. 3) is formed in the center of the lid member 12. The inflow port 12a communicates with the hose 3, and air containing dust flows into the dust collecting case 10 through the inflow port 12a.

As shown in FIG. 3, the operation button 13 is provided so as to be swingable about a support shaft (not shown) projecting left and right at a substantially central portion, and a pressing operation portion 13 a provided at the rear end is provided. By pushing with a finger, a hook portion (not shown) provided on the front end side is released from a groove portion (not shown) provided on the upper end of the front surface of the lid member 12, and the lid member 12 is opened.
On the upper surface of the front end of the operation button 13, a protruding engagement rib 13 b is provided. The engagement rib 13b can be engaged with a frame portion 14a of a shutter body 14 that is rotatably provided on the lid member 12.

  The shutter body 14 is a member that opens and closes the inlet 12a of the lid member 12. When the dust collecting case 10 is housed in the cleaner body 2 (see FIG. 2, the same applies hereinafter), the protruding portion 14b is pressed. Thus, the frame portion 14 a is configured to be positioned above the front end of the operation button 13. As a result, even when the pressing operation portion 13a is accidentally pressed by a hand holding the gripping portion 16 when the dust collecting case 10 is taken out from the cleaner body 2, the swing of the operation button 13 is restricted, and the hook described above The engagement between the part and the groove part is maintained. Therefore, the lid member 12 is prevented from opening unexpectedly when the dust collecting case 10 is taken out from the cleaner body 2. However, the shutter body 14 is not an essential configuration. Moreover, you may provide the non-return valve which obstruct | occludes the opening of the inflow port 12a so that the dust accumulated on the dust container 20 may not spill out from the inflow port 12a. The check valve is preferably made of an elastic material such as rubber. The check valve is composed of three fan-shaped valves and a cylindrical tube portion, and the arc portion of each valve is swingably supported on the inner surface of the tube portion. When air is not flowing in from the inlet 12a, the check valve is in a state in which the opening of the inlet 12a is closed, and in a state where air flows in from the inlet 12a, the check valve is against the elastic force due to wind pressure. Then, it is elastically deformed to the downstream side, that is, the inner side of the dust collecting case 10. Accordingly, the inlet 12a is opened in a state where air flows from the inlet 12a.

Further, as shown in FIGS. 4, 5, and 8, two protrusions 12 b and 12 b that protrude toward the dust container 20 are provided inside the lid member 12 (inside the dust collection case 10). It has been. The protrusions 12b and 12b are thin in the upward direction and have a wide plate shape in the left-right direction and the front-rear direction when the lid member 12 is closed. As shown in FIG. It protrudes substantially perpendicularly to the inner surface of the lid member 12 from the left and right side portions of the inflow port 12a. Therefore, the protrusions 12b and 12b are provided so as to protrude in a substantially front-rear direction, that is, a substantially horizontal direction. The protrusions 12b and 12b may be rod-shaped instead of flat. The protruding portions 12b and 12b may have a shape that becomes narrower as they move away from the inner surface of the lid member 12 (toward the distal end portions 12c and 12c). Moreover, the shape which becomes wide in the left-right direction may be sufficient as the protrusion parts 12b and 12b move away from the inner surface of the cover member 12 (as it goes to the front-end | tip parts 12c and 12c).
As shown in FIG. 4, such protrusions 12 b and 12 b are located on the inner side of the lower wall portion 21 at a position near the lower wall portion 21 of the dust container 20 with the lid member 12 closed to the case member 11. It is arranged along the (inner surface). In addition, the front-end | tip parts 12c and 12c of the protrusion parts 12b and 12b are bent upwards a little, and are made into the shape in alignment with the lower wall part 21. FIG. As shown in FIG. 8, each of the protrusions 12 b and 12 b is preferably arranged in the vicinity of the left side wall part 23 or the right side wall part 24 rather than the center part. The shape and direction of each of the protrusions 12b and 12b may be formed such that the distance between the two protrusions 12b and 12b increases toward the distal end portions 12c and 12c. The front end portions 12c and 12c of the projecting portions 12b and 12b may contact the lower wall portion 21 or the rear wall portion 22 or may not be in contact with each other. The lower side wall portion 21 is not formed in a direction perpendicular to the inner side surface of the lid member 12, but is positioned on the upper side as the rear side wall portion 22 is closer to the inner side surface of the lid member 12. It is formed obliquely upward. Therefore, the protrusions 12b and 12b are not parallel to the direction along the lower wall portion 21, but are slightly inclined.
In this embodiment, the support shaft of the hinge portion 11a is such that the rotation direction when the lid member 12 opens and closes and the rotation direction when the dust container 20 protrudes and retracts with respect to the case member 11 are substantially the same. And the support shaft 21a (rotation fulcrum) of the dust container 20 are arranged close to each other in the same direction. Accordingly, the protrusions 12 b and 12 b are smoothly inserted into the dust container 20 with the closing operation of the lid member 12. The operation of the protrusions 12b and 12b will be described later.

As shown in FIG. 4, the dust container 20 (dust collecting basket) is arranged in the case member 11 and has a mesh-like filter 20 a that collects large coarse dust on each surface. The shape of the dust container 20 is formed by a frame body (support frame). It is preferable that a filter 20a made of metal, nylon, or the like is covered or adhered to the bottom surface (rear side wall portion 22) other than the opening surface of the dust container 20 and the upper, lower, left, and right surfaces. The dust container 20 has a container shape that is open on the front side and closed on the back side (opens on the upstream side in the air flow direction and closes on the downstream side), and has an inlet 12a for the lid member 12. An opening is directed to the side to collect dust flowing in from the inlet 12a. As shown in FIG. 6, the dust container 20 has a three-dimensional shape that is recessed toward the side opposite to the side on which the inflow port 12 a (see FIG. 4) is formed. The rear side wall part 22, the left side wall part 23, the right side wall part 24, and the upper side wall part 25 are provided. The shape of the dust container 20 may be a cage shape, a three-dimensional shape, a box shape or a container shape with one open surface, or a dustpan shape. The cross-sectional shape of the dust container 20 may be a substantially square shape, a substantially circular shape, or a substantially triangular shape. The cross-sectional shape of the dust container 20 is preferably smaller from the opening surface toward the bottom surface. In the present embodiment, among these side wall portions, the upper side wall portion 25 is rotatably provided with the upper side portion of the adjacent rear side wall portion 22 as a fulcrum, and the dust container is opened from the opening portion 11 b of the case member 11. In a state where 20 protrudes, the upper side wall portion 25 is configured to open upward (see FIG. 5). Moreover, the lower side wall part 21, the rear side wall part 22, the left side wall part 23, and the right side wall part 24 are configured to open downward. A spring member that urges the upper side wall portion 25 in the opening direction with respect to the rear side wall portion 22 may be provided at the rotation fulcrum of the upper side wall portion 25.
In addition, the dust container 20 is comprised so that the upper side wall part 25 may close toward the downward direction by accommodating in the dust collection case 10. FIG.

In addition, as shown in FIG. 4, the upper side wall part 25 is located in the dust container 20 in the side facing the side in which the rotation fulcrum (support axis 21a) is provided.
The dust container 20 has a base portion 26 (see FIG. 6) attached to the bottom surface of the case member 11, and a spring member 30 (see FIG. 7) attached between the base portion 26 and the lower side wall portion 21. It is rotatably supported by the base part 26 via the reference (hereinafter the same). The spring member 30 urges the dust container 20 in a direction to push out the dust container 20 toward the opening 11 b of the case member 11. However, the spring member 30 is not an essential configuration. When there is no spring member 30, the dust container 20 protrudes from the case member 11 by gravity.
As shown in FIG. 6, the lower side wall portion 21 includes support holes 26 b and 26 b provided at the left and right side portions 26 a and 26 a of the base portion 26 with support shafts 21 a and 21 a provided at the left and right lower portions of the lower side wall portion 21. By being pivotally supported by (only one shown), the base 26 is provided so as to be rotatable.

  Such a dust container 20 can be detached from the case member 11 integrally with the base portion 26. Therefore, it can be easily cleaned. Further, when it is desired to wash the dust container 20 with water, the dust container 20 can be easily washed with it removed from the case member 11, and the drying time can be relatively short.

As shown in FIG. 6, the lower side wall portion 21, the rear side wall portion 22, the left side wall portion 23, and the right side wall portion 24 are integrally connected to form a part of the dust container 20. As a result, a container is formed in which two surfaces on the front side and the upper side (the side on which the upper side wall portion 25 is provided) are opened.
Support shafts 25b and 25b project from the left and right side portions of the rear side portion 25c of the upper side wall portion 25 toward the respective sides. On the other hand, receiving portions 22b and 22b are erected at the left and right upper end portions of the adjacent rear side wall portions 22, and support shafts 25b and 25b are supported by the receiving portions 22b and 22b, so that the upper side of the rear side wall portion 22 is supported. An upper side wall portion 25 is rotatably provided around the portion.

  As shown in FIG. 4, a plate-like regulation stopper 25 a protrudes obliquely rearward from the rear side portion 25 c of the upper side wall portion 25. The restriction stopper 25 a comes into contact with a restriction portion 11 d provided on the upper inner wall of the case member 11. That is, the restricting portion 11d is positioned on the turning locus of the restricting stopper 25a when the dust container 20 is pushed out toward the opening 11b of the case member 11.

  As a result, when the dust container 20 is rotated in the direction in which the dust container 20 is protruded by the urging force of the spring member 30, as shown in FIG. 7, the restriction stopper 25a abuts against the restriction portion 11d and the rotation is restricted. The upper side wall part 25 is adjacent to the rear side wall part 22 adjacent to the fulcrum (the rear side part 25c of the upper side wall part 25 is a fulcrum), and the rotation is restricted while the upper side wall part 25 is open upward. That is, the dust container 20 is rotated (projected) in the direction opposite to the direction of air flow when dust is collected, and thus the dust container 20 is opened. The dust collected inside can be easily thrown away into a trash can.

  In addition, when the dust container 20 is protruded by the urging force of the spring member 30, the lid member 12 is pressed and opened from the inside. That is, the opening of the lid member 12 and the protrusion of the dust container 20 can be performed in parallel by one operation of pressing the operation button 13. With the biasing force of the spring member 30, for example, even when the dust container 20 is held in the horizontal direction, the lid member 12 can be opened by one operation of pressing the operation button 13.

As shown in FIG. 9, the filter member 15 provided at the rear portion of the case member 11 includes, for example, a corrugated pleated filter 15 b, and the case member is provided by a hinge 15 a provided at the lower portion of the case member 11. 11 is openable and closable. Usually, the filter member 15 is locked in a closed state by a hook 17 a of a locking portion 17 provided on the upper portion of the case member 11.
The filter member 15 functions as a second filter that filters and collects fine fine dust that has passed through the dust container 20. Therefore, the opening of the filter 20 a of the dust container 20 is coarser (larger) than the opening of the filter 15 b of the filter member 15.

Next, an operation when the dust collected in the dust container 20 is discarded will be described.
When the pressing operation portion 13a of the operation button 13 is pressed when the dust is thrown into a trash box or the like, a hook portion (not shown) is detached from the groove portion of the lid member 12, and the lid member 12 is opened. At this time, the lid member 12 is pressed forward by the dust container 20 urged by the spring member 30, and rotates around the hinge portion 11a (see FIG. 5). At the same time, as shown in FIG. 7, the dust container 20 protruding forward by the spring member 30 is restricted from rotating by the restriction stopper 25 a coming into contact with the restriction portion 11 d, and the upper wall portion 25 thereafter It opens upward with the side 25c as a fulcrum. At the same time, the side wall portions excluding the upper side wall portion 25 are integrally opened downward. Thereby, the dust collected inside the dust container 20 is thrown forward, and the dust is discharged.

  Here, generally, light and fluffy fiber dust such as cotton dust tends to be compressed into a lump due to the air flow passing through the dust container 20. Moreover, a part of the fine dust which flowed into the dust container 20 is also collected by the fiber dust which is compressed and solidified in the dust container 20. When the operation of the vacuum cleaner 1 is stopped, the compressed dust lump is easily compressed because the compression force due to the air flow is lost, and the volume of the dust lump tends to increase.

  The dust container 20 of the present embodiment has a shape that expands from the rear side toward the front opening serving as a dust disposal port, and the upper side wall 25 expands the dust disposal port when the accumulated dust is discarded. Therefore, even when the mass of dust stored in the dust container 20 and compressed is expanded, it can be easily discharged from the dust disposal port.

  Moreover, since the protrusion parts 12b and 12b which protrude toward the dust container 20 are provided inside the lid member 12, when the cover member 12 is closed, the lower wall part 21 of the dust container 20 is provided. The protrusions 12b and 12b are positioned so as to overlap with each other and follow the movement of the lid member 12 when the dust is thrown away, so that the protrusions 12b and 12b act to scavenge dust out of the dust container 20. Thereby, dust can be further easily discharged.

Here, an operation when a disposable dust collecting filter paper such as tissue paper is arranged inside the dust container 20 will be described.
Tissue paper T or the like (shown only in FIG. 4; the same applies hereinafter) is mounted in the dust container 20 with the lid member 12 opened before the dust collecting case 10 is attached to the cleaner body 2. The tissue paper T corresponds to a disposable dust collecting filter paper and may be sold as a daily necessities at a convenience store, for example.

  When the lid member 12 is open, the dust container 20 protrudes from the opening 11b, the upper side wall 25 is opened upward, and the side walls other than the upper side wall 25 are integrally opened downward. As a result, the opening is wider than that of a configuration in which the side wall portion is not opened, and a flat tissue paper T or the like can be disposed along the inner surface of the dust container 20.

  Further, when the lid member 12 is closed, the protruding portions 12 b and 12 b provided on the lid member 12 are inserted into the dust container 20 along the lower wall portion 21 of the dust container 20. As a result, the tissue paper T or the like is pushed in so as to be sandwiched between the projecting portions 12 b and 12 b and the lower side wall portion 21 and is adjusted along the lower side wall portion 21. Therefore, a flat tissue paper T or the like can be suitably disposed along the inner surface of the dust container 20. Therefore, the tissue paper T or the like can be suitably pushed into the dust container 20, and the tissue paper T or the like can be prevented from being broken when the dust is sucked.

  Further, by performing an operation of closing the lid member 12, the protrusions 12 b and 12 b press the lower wall portion 21 of the dust container 20 and rotate in a direction in which the dust container 20 is immersed in the case member 11. Therefore, if the operation of closing the lid member 12 is performed, the dust container 20 can be accommodated in parallel with a suitable arrangement of the tissue paper T and the like.

  After doing so, when the case member 11 is attached to the cleaner body 2 and the electric vacuum cleaner 1 is operated for cleaning, the dust sucked into the dust container 20 is disposed upstream of the dust container 20. Most of the deposited tissue paper T and the upstream side thereof are deposited.

  Even in this case, the dust sucked into the dust container 20 tends to become a mass compressed by the air flow. Therefore, the dust is placed on the tissue paper T or the like disposed upstream of the dust container 20 and in the recess of the dust container 20. Wrapped.

  Therefore, even when the lid member 12 is opened and dust is discharged, most of the dust is discharged in a lump state wrapped in the tissue paper T or the like.

  As shown in FIG. 10, fine dust that has passed through the filter 20 a of the dust container 20 adheres to the upstream side of the filter member 15 at the rear of the case member 11. The attached fine dust falls and accumulates in the case member 11 when the operation of the vacuum cleaner ends. The fine dust accumulated in the lower portion travels in the direction of the arrow through the passage R formed between the base portion 26 and the case member 11 and is discharged from the front side of the dust container 20.

  Next, an operation for removing the dust container 20 will be described. Here, as shown in FIG. 11A, the spring member 30 urges the dust container 20 toward the opening with the urging force in the X1 direction, but at the same time, the base portion toward the X2 direction. 26 is also energized. Accordingly, the rear end portion 26c of the base portion 26 is securely locked to the step portion 11e of the case member 11, and the dust container 20 is locked to the case member 11 so as not to drop off.

When removing the dust container 20, as shown in FIG.11 (b), the base 26 is pressed with a finger | toe toward Y1 direction. Then, the base portion 26 is lifted, and the base portion 26 can move to the opening side. Thereby, the dust container 20 can be removed from the case member 11. In this case, since the biasing force in the X2 direction of the spring member 30 is used as a reaction force when a force is applied in the Y1 direction, the dust container 20 can be removed in a stable state without fluttering. .
Since the urging force to the dust container 20 and the urging force to the base portion 26 are performed by one spring member 30, the number of parts can be reduced as compared with the case where these are performed by separate spring members. it can. Thus, the maintenance of the dust container 20 can be carried out by taking it out from the dust collection case 10, so that the maintenance is easy. In addition, internal cleaning of the case member 11 can be easily performed.

The operational effects of this embodiment will be described below.
(1) In the dust container 20 of the present embodiment, the dust container 20 extends from the rear side toward the front opening serving as a dust disposal port, and the upper wall portion 25 expands the dust disposal port when the accumulated dust is discarded. Therefore, even when the mass of compressed dust stored in the dust container 20 expands, it can be easily discharged from the dust disposal port. Therefore, the vacuum cleaner 1 which is easy to throw away dust and is hygienic and easy to use can be obtained.
(2) The dust sucked into the dust container 20 tends to become a mass compressed by the air flow, and is also discharged in a lump when discharged from the dust container 20 through the dust disposal port. The 20 mesh-shaped filter 20a is less likely to be clogged with less dust adhesion and entanglement. For this reason, it is possible to save the trouble of removing the filter 20a simply by throwing away the dust accumulated in the dust container 20.
(3) A part of fine dust such as dust flowing into the dust container 20 is also collected by the fiber dust compressed and solidified in the dust container 20, and the fiber dust wraps the fine dust. Therefore, when the dust accumulated in the dust container 20 is thrown away, the fine dust does not rise and is hygienic.
(4) Since the filter 20a is less likely to be clogged, it is possible to suppress a decrease in the air volume when the electric vacuum cleaner 1 is operated, and it is possible to suppress a decrease in suction force, so that dust on the surface to be cleaned is sucked. A decrease in ability can be suppressed.
(5) The protrusions 12b and 12b follow the movement of the opening of the lid member 12 when the dust is thrown away, and the protrusions 12b and 12b scrape the dust out of the dust container 20, so that the dust can be more easily discharged. In particular, with the lid member 12 closed to the case member 11, the projecting portions 12 b and 12 b are positioned along the inner side (inner side surface) of the lower wall portion 21 at a position near the lower wall portion 21 of the dust container 20. By disposing, most of the compressed dust mass accumulates above the protrusions 12b and 12b. Since the lid member 12 rotates with the lower end as a fulcrum, the projections 12b and 12b are displaced following the movement of the lid member 12 opening, and the projections 12b and 12b scrape most of the dust. Further, the protrusions 12b and 12b are formed substantially perpendicular to the inner surface of the lid member 12 and have a flat plate shape, thereby being substantially perpendicular to the direction in which the protrusions 12b and 12b rotate. Therefore, when the protrusions 12b and 12b are displaced following the movement of the lid member 12 opening, the protrusions 12b and 12b can easily catch dust. Further, when the tip portions 12c and 12c of the projecting portions 12b and 12b are bent slightly upward, the projecting portions 12b and 12b are displaced following the movement of the lid member 12 opening. Further, dust can be prevented from spilling from the tip portions 12c and 12 of the projecting portions 12b and 12b, and the dust can be easily captured. Furthermore, since the protrusions 12b and 12b have a flat plate shape, dust can be prevented from being sandwiched between the two protrusions 12b and 12b, and the protrusion 12b follows the movement of the lid member 12 opening. , 12b is easily displaced from the protrusions 12b, 12b.
(6) Since the upper side wall portion 25 is located on the side facing the side where the rotation fulcrum (support shaft 21a) is provided in the dust container 20, the upper side wall portion 25 is located above and below the case where it is not in this position. The dust container 20 can be greatly opened in the direction.
(7) When the lid member 12 is open, the dust container 20 protrudes from the opening 11b, the upper side wall 25 is opened upward, and the side walls other than the upper side wall 25 are integrally lowered. Since it opens in the direction, it is easy to arrange a flat tissue paper T or the like along the inner surface of the dust container 20.
(8) By performing the operation of closing the lid member 12, the projecting portions 12 b and 12 b press the lower wall portion 21 of the dust container 20 in parallel with this operation, and the dust container 20 is accommodated in the case member 11. can do. Since the upper side wall portion 25 is positioned on the side facing the side where the rotation fulcrum is provided in the dust container 20, the front end of the dust container 20 is moved to the lid member by performing an operation of closing the lid member 12. Since the upper side wall portion 25 is easily closed when pushed by the inner side surface of the dust 12, the dust container 20 can be easily accommodated in the case member 11 even when the protruding portions 12 b and 12 b are not provided.
(9) By performing the operation of closing the lid member 12, the protruding portions 12b and 12b can suitably push the tissue paper T or the like into the dust container 20 (along the inner surface of the dust container 20). It is possible to prevent the tissue paper T and the like from being broken during dust suction. In particular, the front end portions 12c, 12c of the projecting portions 12b, 12b reach the vicinity of the lower side wall portion 21 or the rear side wall portion 22, so that the tissue paper T or the like can be suitably pushed into the dust container 20. Further, since the tip portions 12c and 12c of the projecting portions 12b and 12b are bent, when the tissue paper T or the like is pushed into the dust container 20, the tip portions 12c and 12c of the projecting portions 12b and 12b. Can prevent the tissue paper T and the like from being broken. In addition, when there is no protrusion part 12b, 12b, it is preferable to push the tissue paper T etc. into the dust container 20 by a user's hand.
(10) The dust container 20 can be accommodated in parallel with a suitable arrangement of the tissue paper T or the like.
(11) Since the tissue paper T or the like can be suitably disposed, even when the lid member 12 is opened and the dust is discharged, most of the dust is in a lump state wrapped in the tissue paper T or the like. It is sanitary because no dust rises.
(12) By disposing the tissue paper T or the like of the dust container 20, it is difficult for dust to adhere to the filter 20a of the dust container 20, and clogging of the filter 20a can be prevented. Can be prevented.

Here, the support portions (support points) of the receiving portions 22b and 22b and the support shafts 25b and 25b are located outside the case member 11 (outside through the opening) in a state where the dust container 20 protrudes from the case member 11. You may comprise as follows.
With this configuration, the upper side wall portion 25 of the dust container 20 can be further opened upward, and even if dust adheres to the filter 20a of the dust container 20, this can be removed. Can be cleaned easily.

Further, as shown in FIG. 12, not only the upper side wall portion 25 of the dust container 20 ′ but also the lower side wall portion 21, the left side wall portion 23, and the right side wall portion 24 are opened and closed with the respective side portions of the rear side wall portion 22 as fulcrums. You may comprise. That is, when the dust container 20 ′ protrudes from the dust collection case 10, the dust container 20 ′ is developed in a substantially flat shape.
By configuring in this way, each side wall portion of the dust container 20 ′ is completely opened, so that even when a mass of compressed dust stored in the dust container 20 ′ expands, it can be easily obtained from the dust disposal port. Further, the dust container 20 ′ can be easily cleaned.

  The fulcrum portion may be provided with a hinge (not shown), or the fulcrum portion may be configured to be bent from the thin portion by forming the fulcrum portion thin. Further, a spring member (not shown) may be interposed in at least one side portion so that the corresponding side wall portion is urged in the opening direction.

Moreover, you may comprise the side wall part which can be opened and closed independently or in combination suitably.
Furthermore, the shape of the dust container 20 (20 ′), the number of side walls, and the like can be arbitrarily set.
