When the dust concentrated in the dust collecting box is to be discarded, it is desirable to sanitize it without being exposed to dust.

According to the invention described in Patent Document 1, it is proposed that the storage portion for accumulating the collected dust is formed into a disk shape, and when the storage portion is opened when dust is to be discarded, the storage portion can be prevented from being horizontal. A technique that discards dust by accidentally spilling. However, the collected dust is compressed in the flat bottom of the storage portion, and when the dust is discarded, the dust easily spreads outward and the dust is easily lifted, making it difficult to discard the dust.

In the invention described in Patent Document 1, it is proposed that dust can be easily discarded by using a dust collecting filter paper of a disposable paper type such as a paper towel in the storage portion, and a rib portion is provided inside the dust collecting box body. The paper towel is attached by pressing the tissue along the shape of the storage portion. However, the zoned ribs are formed to sandwich the collected dust. However, when discarded, there is a problem that dust is stuck and it is difficult to fall.

According to the invention of Patent Document 2, when the dust is discarded, the dust container is allowed to protrude from the dust box body, and the dust container is opened to expand up and down or left and right, so that the dust can be easily discharged. However, since the dust container having the depth is expanded up and down or left and right, when the dust is discarded, the opening degree of the dust container is limited, and dust may adhere to the inside of the dust container. It is desirable to improve the convenience of cleaning dust attached to a dust container having a depth.

In the invention described in the patent document 2, it is proposed to reduce the contamination of the dust container by using a dust collecting filter paper such as a paper towel or the like on the upstream side of the dust collecting container as a collecting means for collecting dust. However, it is difficult to attach a paper towel or the like along the wall surface of the dust container having a depth. When a paper towel or the like is installed, if a space is formed between the dust and the wall surface of the dust container, the paper towel may be allowed to be attracted when the dust is attracted. damaged.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a vacuum cleaner which is easy to discard dust and which is excellent in usability.

The dust collecting case 10 is detachably attached to the storage chamber 2b, and is periodically taken out from the storage chamber 2b after the cleaning is completed. Then, the dust collected inside the dust collecting box 10 is thrown into a garbage box or the like. The storage chamber 2b is formed on the front side of the inside of the cleaner body 2, and the electric blower is disposed on the rear side of the inside of the cleaner body 2.

The lid body 2a is opened when the dust box body 10 is taken in and out, and is closed during the cleaning operation. The direction in which the dust collecting case 10 is attached to and detached from the storage chamber 2b is substantially in the vertical direction.

As shown in FIG. 3, the dust collecting case 10 includes a cylindrical case member 11 and a cover member 12 rotatably provided at a front portion of the case member 11, and inside the case member 11, There is provided a dust container 20 as a function of the first filter for separating air from dust (refer to Fig. 4). A filter member 15 is provided at the rear of the box member 11 (refer to Fig. 4). The front opening (opening 11b) of the casing member 11 is closed by the cover member 12, and the rear portion of the casing member 11 is opened by the filter member 15.

As shown in Fig. 5, the cover member 12 is provided to be rotatable about a hinge portion 11a provided at a lower portion of the front end of the casing member 11, by operation: releasing the cover provided on the upper front portion of the casing member 11 The operation button 13 (refer to FIG. 3) is used to turn it downward, and the opening 11b of the case member 11 is opened. In a state where the lid member 12 is opened, the dust container 20 is caused to protrude through the opening portion 11b. In a state where the dust collecting container 20 protrudes from the opening portion 11b, the rear side of the dust collecting container 20 is positioned in the dust collecting box 10. However, in a state where the dust container 20 protrudes from the opening portion 11b, the rear side of the dust container 20 may be located outside the dust box body 10. In other words, in a state where the dust container 20 protrudes from the opening portion 11b, the entire dust container 20 may be located outside the dust box body 10. The cover member 12 may be provided to be rotatable about a hinge portion provided at an upper portion of the front end of the casing member 11 instead of being provided so as to be rotatable about a hinge portion 11a provided at a lower portion of the front end portion of the casing member 11.

In the central portion of the cover member 12, a circular inflow port (suction port) 12a is formed in the opening (refer to Fig. 3). The inflow port 12a communicates with the hose 3, and the dust-containing air flows into the dust collecting box body 10 through the inflow port 12a.

On the upper end of the front end of the operation button 13, an engagement rib 13b of a ridge is provided. The engaging rib 13b is engageable with a frame portion 14a of the shutter body 14 that is rotatably provided by the cover member 12.

The baffle body 14 is a member that opens and closes the inflow port 12a of the lid member 12, and the dust box body 10 is housed in the cleaner body 2 (refer to Fig. 2, the same applies hereinafter), and the frame is pressed by the protrusion 14b. The portion 14a is located above the front end of the operation button 13. In this way, when the dust box body 10 is taken out from the cleaner body 2, even if the hand held by the grip portion 16 accidentally presses the pressing operation portion 13a, the swing of the operation button 13 can be restricted, and the hook can be maintained. The part is engaged with the groove. Thus, it is possible to prevent the cover member 12 from being inadvertently opened when the dust box body 10 is taken out from the cleaner body 2. However, the baffle body 14 is not an essential configuration. In order to prevent dust accumulated in the dust collecting container 20 from overflowing from the inflow port 12a, a check valve for closing the opening of the inflow port 12a may be provided. The check valve is preferably made of an elastic member such as rubber. The check valve is composed of a fan-shaped three-piece valve body and a cylindrical tubular portion, and the arc-shaped portion of each valve body is rotatably supported by the inner surface of the cylindrical body. In a state where the air does not flow from the inflow port 12a, the check valve is in a state in which the opening of the inflow port 12a is closed, and in a state where the air flows in from the inflow port 12a, the check valve is biased against the elastic force by the wind pressure. The side is also elastically deformed on the inner side of the dust box body 10. Thereby, the inflow port 12a is opened in a state where air flows in from the inflow port 12a.

As shown in FIG. 4, FIG. 5, and FIG. 8, the inside of the cover member 12 (inside the dust collecting body 10) is provided with two protruding portions 12b and 12b that protrude toward the dust collecting container 20. In a state in which the lid member 12 is closed, the protruding portions 12b and 12b are formed in a flat shape which is thin in the vertical direction and wide in the left-right direction and the front-rear direction, and as shown in Fig. 5, flows from the inner side surface of the lid member 12. The left and right side portions of the inlet 12a are protruded substantially perpendicularly to the inner side surface of the cover member 12. Therefore, the protruding portions 12b and 12b are protruded in the substantially front-rear direction, that is, in the substantially horizontal direction. The protruding portions 12b and 12b may be formed in a rod shape instead of the flat plate shape. The protruding portions 12b and 12b may be formed to be tapered as they are away from the inner side surface of the cover member 12 (toward the front end portions 12c and 12c). The protruding portions 12b and 12b may have a shape that widens in the left-right direction as they move away from the inner side surface of the cover member 12 (toward the front end portions 12c and 12c).

As shown in FIG. 4, the protruding portions 12b and 12b are disposed along the lower side wall portion 21 in the vicinity of the upper side of the lower side wall portion 21 of the dust container 20 in a state where the lid member 12 is closed to the box member 11. The inside (inside). The front end portions 12c and 12c of the protruding portions 12b and 12b are formed to be slightly bent upward and along the shape of the lower side wall portion 21. As shown in FIG. 8, each of the protruding portions 12b and 12b is preferably disposed closer to the left side wall portion 23 or the right side wall portion 24 than the center portion. The shape and direction of each of the protruding portions 12b and 12b may be formed so as to be spaced apart from the distal end portions 12c and 12c so as to be spaced apart from each other. The front end portions 12c and 12c of the protruding portions 12b and 12b may be in contact with the lower side wall portion 21 or the rear side wall portion 22, and may be non-contact. The lower side wall portion 21 is not formed in a direction perpendicular to the inner side surface of the cover member 12, but is formed obliquely upward with respect to the inner side surface of the cover member 12 so as to be located on the upper side as approaching the rear side wall portion 22. . The protruding portions 12b, 12b are not parallel to the direction along the lower side wall portion 21, but are slightly inclined.

In the present embodiment, the support shaft of the hinge portion 11a and the branch of the dust container 20 are arranged such that the rotation direction when the lid member 12 is opened and closed is substantially the same as the rotation direction when the dust container 20 is opened and closed with respect to the box member 11. The shaft 21a (rotational fulcrum) is arranged close to the same direction. Thereby, the protruding portions 12b and 12b are smoothly inserted into the dust collecting container 20 in accordance with the closing operation of the lid member 12. The action on the protruding portions 12b and 12b will be described later.

As shown in Fig. 4, the dust collector 20 (dust collecting basket) is disposed in the casing member 11, and has a mesh-like filter 20a for collecting large coarse dust on each surface. The shape of the dust container 20 is formed by a frame (skeleton). The bottom surface (rear side wall portion 22) other than the opening surface of the dust container 20 is covered or attached with a filter 20a made of metal or nylon on the upper, lower, left, and right sides. The dust container 20 has a container shape in which the front side is opened and closed inside (the upstream side in the flow direction of the air is opened, and the downstream side is closed), and the opening faces the inflow port 12a side of the cover member 12, and flows in from the inflow port 12a. Dust collection. As shown in Fig. 6, the dust container 20 has a three-dimensional shape recessed toward the side opposite to the side where the inflow port 12a (refer to Fig. 4) is formed, and the side wall portion includes the lower side wall portion 21 and the rear side. The side wall portion 22, the left side wall portion 23, the right side wall portion 24, and the upper side wall portion 25. The shape of the dust container 20 may be a casing shape, a three-dimensional shape, a box shape, or a container shape in which one side is open, and the shape may be a 畚箕 shape. The cross-sectional shape of the dust container 20 may be substantially quadrangular, substantially circular, or substantially triangular. The cross-sectional shape of the dust container 20 is preferably small from the opening surface toward the bottom surface. In the present embodiment, among the 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 20 protrudes from the opening portion 11b of the box member 11. In the state, the upper side wall portion 25 is opened upward (refer to Fig. 5). 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 opposed to open downward. At the pivot point of the upper side wall portion 25, a spring member that biases the rear side wall portion 22 in a direction in which the upper side wall portion 25 is opened may be provided.

The dust container 20 is retracted in the dust box body 10 to close the upper side wall portion 25 downward.

As shown in Fig. 4, the upper side wall portion 25 is positioned on the side opposite to the side on which the pivot point (the support shaft 21a) is provided.

The dust container 20 has a base portion 26 (refer to FIG. 6) attached to the bottom surface of the box member 11 and interposed between the base member 26 and the lower side wall portion 21 (refer to the seventh section). The figure, hereinafter the same), is rotatably supported by the base 26. The spring member 30 is biased in a direction in which the dust collecting container 20 is pushed toward the opening portion 11b of the casing member 11. However, the spring member 30 is not an essential configuration. If there is no spring member 30, the dust container 20 is protruded from the box member 11 by gravity.

As shown in Fig. 6, the lower side wall portion 21 is pivotally supported by the support shafts 26a and 21b provided at the left and right lower portions 26a and 26a of the base portion 26 by the support shafts 21a and 21a provided at the left and right lower portions of the lower side wall portion 21. (only one of them is shown), and is provided to be freely rotatable with respect to the base portion 26.

The dust container 20 can be detached from the casing member 11 integrally with the base portion 26. So you can simply clean it. Further, even when the dust container 20 is washed with water, it can be easily washed with water in a state where it is detached from the box member 11, and the drying time can be shortened.

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 each other to constitute a part of the dust container 20, and these portions are connected to each other. : Containers having openings on both sides of the front side and the upper side (provided with the side of the upper side wall portion 25).

On the left and right side portions of the rear side portion 25c of the upper side wall portion 25, the support shafts 25b and 25b are respectively protruded toward the side. On the other hand, at the left and right upper end portions of the adjacent rear side wall portions 22, support portions 22b and 22b are erected, the support shafts 25b and 25b are supported by the support portions 22b and 22b, and the upper side wall portion 25 is disposed to be rotatable. The upper side portion of the rear side wall portion 22 is rotated.

As shown in Fig. 4, a plate-shaped restricting stopper 25a is protruded obliquely rearward from the rear side portion 25c of the upper side wall portion 25. The restricting stopper 25a is in contact with the restricting portion 11d provided on the upper inner wall of the casing member 11. That is, the restricting portion 11d is located on the rotational locus of the restricting stopper 25a when the dust collecting container 20 is pushed toward the opening portion 11b of the casing member 11.

Thereby, when the dust container 20 is rotated in a direction in which the spring pressure of the spring member 30 is projected, as shown in FIG. 7, the restricting stopper 25a abuts against the restricting portion 11d to restrict the rotation, and finally, the upper side wall portion 25 The upper side portion of the adjacent rear side wall portion 22 is used as a fulcrum (the rear side portion 25c of the upper side wall portion 25 is used as a fulcrum), and is opened upward and the rotation is restricted. In other words, the dust container 20 is rotated (projected) in a direction opposite to the direction in which the air flows when the dust is collected, and the dust collected in the dust container 20 can be easily thrown into the dustbin. Wait.

When the dust container 20 protrudes by the elastic pressure of the spring 30, the cover member 12 is pressed from the inside to push it away. That is, with one operation operation of pressing the operation button 13, it is possible to simultaneously perform the opening of the cover member 12 and the protrusion of the dust container 20. By the elastic pressure of the spring member 30, for example, in a state where the dust container 20 is held in the horizontal direction, the lid member 12 can be opened by one operation operation of pressing the operation button 13.

As shown in Fig. 9, the filter member 15 provided at the rear portion of the casing member 11 is provided with, for example, a filter 15b for performing wavy wrinkles, and a hinge 15a provided at a lower portion of the casing member 11, It is provided so that the case member 11 can be freely opened and closed. Usually, the filter member 15 is locked in a closed state by the hook portion 17a of the locking portion 17 provided at the upper portion of the casing member 11.

The filter member 15 functions as a second filter for collecting and collecting fine fine dust passing through the dust container 20. Therefore, the mesh of the filter 20a of the dust container 20 is a mesh which is thicker (larger) than the filter 15b of the filter member 15.

Next, the action when the dust collected in the dust collection container 20 is discarded will be described.

When the dust is thrown into the garbage can or the like, when the pressing operation portion 13a of the operation button 13 is pressed, the hook portion (not shown) is detached from the groove portion of the cover member 12, and the lid member 12 is opened. At this time, the lid member 12 is pressed forward by the dust container 20 that is biased by the biasing member 30, and is rotated by the hinge portion 11a as a center (refer to FIG. 5). At the same time, the dust container 20 projecting forward by the spring member 30 causes the restricting stopper 25a to abut against the restricting portion 11d to restrict rotation as shown in Fig. 7, and the upper side wall portion 25 is fulcrum with its rear side portion 25c as a fulcrum And open upwards. At the same time, the side wall portions excluding the upper side wall portion 25 are integrated and open downward. Thereby, the dust collected on the inside of the dust container 20 is discharged to the front, and the dust is discharged.

In general, fluffy fiber dust such as cotton wool is easily compressed and agglomerated by the air flow passing through the dust container 20. On the other hand, a part of the fine dust that has flowed into the dust container 20 can be collected by the fiber dust which is compressed and agglomerated in the dust container 20. In the agglomerated state of the compressed dust, when the operation of the cleaner 1 is stopped, the compressive force due to the air flow disappears, and it is easy to expand, and the volume of the dust agglomerates tends to increase.

The dust container 20 of the present embodiment has a shape in which the front side opening toward the dust discarding opening is expanded from the rear side, and when the accumulated dust is discarded, the upper side wall portion 25 is opened to expand the dust discarding opening. Even if the compressed dust agglomerated in the dust container 20 is expanded, it can be easily discharged from the dust discarding port.

On the inner side of the cover member 12, protrusions 12b and 12b projecting toward the dust container 20 are provided, so that when the cover member 12 is closed, its position overlaps along the lower side wall portion 21 of the dust container 20, and will follow The operation of opening the cover member 12 when the dust is discarded serves to cause the protruding portions 12b and 12b to pry the dust out of the dust collecting container 20. Thereby, it is easier to discharge the dust.

Here, the action in the case where a dust collecting filter paper of a disposable paper type such as a paper towel is disposed inside the dust container 20 will be described.

The paper towel T or the like (illustrated only in Fig. 4, the same applies hereinafter), before the dust box body 10 is attached to the cleaner body 2, the lid member 12 is attached to the dust container 20 in a state where the lid member 12 is opened. The paper towel T is equivalent to a disposable dust collecting filter paper, and is sold as a commodity, for example, in a convenience store.

In a state where the lid member 12 is opened, the dust container 20 protrudes from the opening portion 11b, the upper side wall portion 25 opens upward, and the side wall portion other than the upper side wall portion 25 is integrally opened downward, so that the side wall portion is not opened. When the opening is widened, a flat paper towel T or the like can be placed along the inner surface of the dust container 20.

When the lid member 12 is closed, the protruding portions 12b and 12b provided in the lid member 12 are inserted into the dust collecting container 20 along the lower side wall portion 21 of the dust container 20. Thereby, the paper towel T or the like is pushed into between the protruding portions 12b and 12b and the lower side wall portion 21, and is adjusted along the lower side wall portion 21. Therefore, the flat paper towel T or the like can be appropriately disposed along the inner surface of the dust container 20. Therefore, the paper towel T or the like can be appropriately pushed into the dust container 20, and when the dust is attracted, the paper towel T or the like can be prevented from being damaged.

By the operation of closing the lid member 12, the protruding portions 12b and 12b are pressed against the lower side wall portion 21 of the dust container 20, and the dust container 20 is rotated in a direction that does not enter the casing member 11, so that if When the lid member 12 is closed, the paper towel T can be appropriately disposed and the dust container 20 can be accommodated at the same time.

Then, the case member 11 is attached to the cleaner body 2, and the cleaner 1 is operated to perform cleaning, and the dust sucked into the dust container 20 is mostly deposited on the paper towel T disposed upstream of the dust container 20 and the like. Its upstream side.

In this case, the dust that has been sucked into the dust container 20 is likely to be compressed and agglomerated by the air flow. Therefore, in the upstream of the dust container 20, the paper towel T or the like placed in the concave portion of the dust container 20 is wrapped.

Then, when the lid member 12 is opened to discharge the dust, almost all of the dust is discharged into the agglomerated state surrounded by the paper towel T or the like.

As shown in Fig. 10, the fine dust passing through the filter 20a of the dust container 20 adheres to the upstream side of the filter member 15 at the rear of the casing member 11. The fine dust adhered will fall and accumulate in the casing member 11 when the operation of the cleaner is completed. The fine dust deposited on the lower portion is discharged from the front side of the dust container 20 by the passage R formed between the base portion 26 and the case member 11 as the arrow travels.

Next, an operation of the case where the dust collection container 20 is removed will be described. As shown in Fig. 11 (a), the spring member 30 biases the dust container 20 toward the opening side by the elastic pressure in the X1 direction, and simultaneously biases the base portion 26 in the X2 direction. Thereby, the rear end portion 26c of the base portion 26 is surely locked to the segment portion 11e of the case member 11, and the dust container 20 is locked to the case member 11 without being detached.

When the dust container 20 is removed, as shown in Fig. 11(b), the base portion 26 in the Y1 direction is pressed with a finger. In this way, the base portion 26 floats and can move toward the opening side. Thereby, the dust container 20 can be detached from the box member 11. In this case, the spring pressure in the X2 direction of the spring member 30 as the reaction force when the force is applied in the Y1 direction is utilized, so that the dust container 20 can be removed in a stable state without rattling.

Since the spring force of the dust container 20 and the spring pressure toward the base portion 26 are performed by one spring member 30, the number of parts can be reduced as compared with the manner in which these operations are performed by using different spring members. Since the dust container 20 can be taken out from the dust box body 10 for maintenance, it is easy to perform maintenance. Moreover, the inside of the case member 11 can be easily cleaned.

The operation and effect of the present embodiment will be described below.

(1) In the dust container 20 of the present embodiment, the front side opening toward the dust discarding opening is expanded from the rear side, and when the accumulated dust is discarded, the upper side wall portion 25 is opened to expand the dust discarding opening, so that even When the compressed dust agglomerates contained in the dust container 20 are expanded, they can be easily discharged from the dust discarding port. Thus, it is possible to obtain a vacuum cleaner 1 which is easy to discard dust and which is excellent in hygiene and ease of use.

(2) The dust sucked into the dust container 20 is easily compressed and agglomerated by the air flow, and is discharged as agglomerated when the dust container 20 is discharged through the dust discarding port, so that the dust is in the mesh of the dust container 20. In the case of the filter 20a, less dust is attached or entangled, and clogging is less likely to occur. Therefore, as long as the dust accumulated in the dust container 20 is discarded, the procedure for dusting the filter 20a is saved.

(3) By compressing the agglomerated fiber dust in the dust container 20, a part of fine dust such as dust that has flowed into the dust container 20 is collected, and the fiber dust surrounds the fine dust, so that it accumulates in the dust. When the dust in the dust accommodating chamber 20 is discarded, fine dust does not rise and the hygiene is good.

(4) Since the clogging of the filter 20a does not occur, it is possible to prevent a decrease in the air volume when the cleaner 1 is operated, and it is possible to prevent a decrease in the suction force, so that the ability to attract the dust on the surface to be cleaned can be prevented from being lowered.

(5) Following the operation of opening the lid member 12 when the dust is discarded, the protruding portions 12b and 12b scrape the dust from the dust container 20, so that the dust can be more easily discharged. In particular, in a state where the lid member 12 is closed to the box member 11, the protruding portions 12b and 12b are disposed so as to be located along the inner side (inner side surface) of the lower side wall portion 21 near the upper side of the lower side wall portion 21 of the dust container 20. Then, most of the compressed dust block is deposited on the upper side of the protruding portions 12b, 12b. Since the lower end of the cover member 12 is pivoted as a fulcrum, the lid member 12 is followed by the opening operation, and the projections 12b and 12b are displaced to scrape most of the dust. Further, the protruding portions 12b and 12b are formed so as to be substantially perpendicular to the inner side surface of the lid member 12, and have a width of a certain extent in a direction substantially perpendicular to the direction of rotation of the protruding portions 12b and 12b by being formed into a flat shape. Therefore, when the protrusions 12b, 12b are displaced in accordance with the opening operation of the cover member 12, the projections 12b, 12b easily catch dust. Further, by bending the front end portions 12c, 12c of the protruding portions 12b, 12b slightly upward, when the protruding portions 12b, 12b are displaced in accordance with the opening operation of the cover member 12, dust can be prevented from the protruding portions 12b, 12b. The front end portions 12c and 12c overflow and fall, and dust can be easily caught. Further, by making the protruding portions 12b and 12b flat, it is possible to prevent dust from being interposed between the two protruding portions 12b and 12b, and when the protruding members 12b and 12b are moved in following the opening operation of the cover member 12, the dust is easy. It is separated from the protruding portions 12b, 12b.

(6) The upper side wall portion 25 is positioned on the side opposite to the side on which the rotation fulcrum (the support shaft 21a) is provided, so that the dust collecting container can be disposed as compared with the case where the position is not provided at the position. 20 is opened vertically in the up and down direction.

(7) When the lid member 12 is opened, the dust container 20 protrudes from the opening portion 11b, the upper side wall portion 25 is opened upward, and the side wall portions other than the upper side wall portion 25 are integrally opened downward, so that a flat paper towel is easily formed. T or the like is disposed along the inner surface of the dust container 20.

(8) By performing the operation of closing the lid member 12 and simultaneously pressing the protruding portions 12b and 12b against the lower side wall portion 21 of the dust container 20, the dust container 20 can be housed in the box member 11. The upper side wall portion 25 is located on the side opposite to the side on which the rotation fulcrum is provided, so that the operation of closing the cover member 12 causes the dust container to be pressed by the inner side surface of the cover member 12. At the front end of 20, the upper side wall portion 25 is easily closed, so that the dust collecting container 20 can be easily accommodated in the casing member 11 without the protruding portions 12b and 12b.

(9) By performing the operation of closing the lid member 12, the paper towel T or the like can be appropriately pushed into the dust container 20 (along the inner surface of the dust container 20) by the protruding portions 12b and 12b, when dust is present It can prevent the paper towel T from being damaged when attracted. In particular, by allowing the front end portions 12c and 12c of the protruding portions 12b and 12b to reach the vicinity of the lower side wall portion 21 or the rear side wall portion 22, the paper towel T or the like can be appropriately pushed into the dust containing chamber 20, and by When the front end portions 12c and 12c of the protruding portions 12b and 12b are bent, when the paper towel T or the like is pushed into the dust accommodating chamber 20, the front end portions 12c and 12c of the ten protruding portions 12b and 12b can prevent the paper towel T from being damaged. . If the protruding portions 12b and 12b are not provided, it is preferable to push the paper towel T or the like into the dust receiving chamber 20 by the user's hand.

(10) The proper arrangement of the paper towel T or the like and the storage of the dust container 20 can be simultaneously performed.

(11) Since the paper towel T or the like can be appropriately disposed, when the lid member 12 is opened to discharge the dust, almost all the dust is discharged by the paper towel T or the like, and the dust is lifted. More sanitary.

(12) When the paper towel T or the like of the dust container 20 is disposed, the dust does not easily adhere to the filter 20a of the dust container 20, and clogging of the filter 20a can be prevented, so that the attraction force can be prevented from being lowered.

The support portions 22b and 22b and the support portions (fulcrums) of the support shafts 25b and 25b may be located outside the case member 11 (through the outside of the opening) in a state where the dust container 20 protrudes from the case member 11.

By making such a structure, the upper side wall portion 25 of the dust container 20 can be opened more vertically upward, and even if dust adheres to the filter 20a of the dust container 20, it can be easily cleaned with a brush or the like. .

As shown in Fig. 12, the upper side wall portion 25 of the dust container 20' may be formed not only, but also the side wall portion of the rear side wall portion 22 as a fulcrum, and the lower side wall portion 21, the left side wall portion 23, and the right side wall portion 24 may be formed. Can be opened and closed. In other words, in a state in which the dust container 20' protrudes from the dust collecting box 10, it can be expanded into a substantially flat shape.

By making such a structure, the side wall portions of the dust container 20' are completely opened. Therefore, even if the compressed dust agglomerates contained in the dust container 20' expand, it can be easily discharged from the dust disposal port. It is easy to clean the dust container 20'.

In the fulcrum portion, a hinge (not shown) may be provided, or the thickness of the fulcrum portion may be made thin, and the portion formed thinner may be freely bent. Alternatively, the spring member (not shown) may be biased in a direction in which the corresponding side wall portion is opened at least at one side.

It is also possible to form the openable and closable side wall portions individually or in appropriate combination.

Further, the shape of the dust container 20 (20'), the number of side wall portions, and the like can be arbitrarily set.

The dust collecting container 20 may be provided in the case member 11 instead of being sandwiched between the cover member 12 and the case member 11, as in Patent Document 1, provided to be sandwiched between the case member 11 and the filter member. 15 is also possible.
