Description

  The present invention relates to an electric vacuum cleaner, and more particularly to an electric vacuum cleaner that can easily discharge dust and can reduce maintenance work for a filter provided in a dust collection case.

Conventionally, as a vacuum cleaner having a dust collection case that can easily discharge the dust collected in the dust collection case and reduce the maintenance work of the filter, for example, a vacuum cleaner described in Patent Document 1 is known. ing.
The vacuum cleaner described in Patent Document 1 includes a dust collecting container including an outer case, an inner case, and a filter device, and the filter device includes a main surface facing the outer case, and an end of the main surface from the main surface. The main body and the side surface form a storage part for collecting dust.

Since such a storage part is formed in a dish shape having a bottom by the main surface and the side surface, when removing the filter device from the outer case in order to discard the dust stored in the storage part, the storage part should be leveled. Even without it, the dust accumulated in the reservoir can be smoothly thrown away without spilling unexpectedly.
In addition, tissue paper, which is a disposable filter, can be attached between the outer case and the filter device. When the filter device is attached to the outer case, the tissue paper is attached to the filter device so as to follow the shape of the reservoir. Since the pressing rib is provided, the tissue paper can be attached and the filter device can be attached together.

Moreover, what was described in patent document 2 is known as an electric vacuum cleaner which can discharge | emit easily the dust collected by the dust collection case.
In the vacuum cleaner described in Patent Document 2, the dust container is provided so as to be able to protrude from the opening of the dust collection case, and is disposed on the upstream side of the dust container in the dust collection case. Dust filter paper is arranged.
When cleaning is performed by operating such a vacuum cleaner, the dust sucked into the dust container is collected by a disposable dust collecting filter paper disposed on the upstream side of the dust container. Then, the dust accumulated on the dust collecting filter paper is compressed into an air flow and becomes a lump. Thereby, dust can be easily discharged.

JP 2007-244844 A JP 2008-194085 A

In the electric vacuum cleaner of Patent Document 1, dust is compressed by an air flow during operation, but when not being operated, the dust is not wrapped in a disposable dust collecting filter paper and spreads. For this reason, when a large amount of dust is collected, the dust is caught on the inner wall of the dust collection case, and it is necessary to scrape the dust when discharging. Therefore, in the electric vacuum cleaner of patent document 1, when dust is scraped off, fine dust rises and it is not desirable in terms of hygiene.
In addition, dust is likely to adhere to the rib for pressing the tissue paper against the filter device, and when the filter device is removed to discharge the dust, the rib protrudes from the outer case, which is not hygienic. .
Further, since the rib is inserted into the storage portion, it is necessary to reduce the volume of dust collection and frequently throw out the dust. For this reason, it took time and effort.

  In this respect, the electric vacuum cleaner of Patent Document 2 can easily discharge dust, and since there is no rib in the dust container, the dust is not caught on the rib or attached to the dust. However, when disposing a disposable dust collecting filter paper, if it is not mounted along the inner surface of the dust container, there is a risk of tearing due to the dust-containing air flow. When such a tear occurs, there is a risk that the filter provided on the downstream side may be clogged faster than when the dust collecting filter paper is not torn.

  The present invention solves the above-described conventional problems, and provides a vacuum cleaner that can easily discharge dust collected in a dust collection case and can reduce the maintenance of a filter provided in the dust collection case. The purpose is to provide.

The present invention relates to a vacuum cleaner having a vacuum cleaner body having a built-in electric blower, and a dust collection case that is detachably provided in the vacuum cleaner body and includes a dust container for collecting dust inside. A disposable dust collecting filter paper disposed in the opening of the dust collecting case so as to be freely opened and closed and interposed on the upstream side in the dust suction direction of the dust container is sandwiched between the dust collecting case and the dust collecting case. A lid member provided in a possible manner, wherein the dust collecting filter paper is brought into close contact with the dust container by a suction force when the electric blower is driven with the lid member opened. To do.
According to this vacuum cleaner, the dust collecting filter paper can be sucked into the dust container using the suction force generated by the driving of the electric blower, and can be brought into close contact with the dust container.

Also, a vacuum cleaner body incorporating an electric blower, a dust collection case chamber provided in the vacuum cleaner body, and a dust container for detachably provided in the dust collection case chamber for collecting dust inside A vacuum cleaner having a dust collecting case, wherein the dust collecting case chamber is provided with a main body intake port for taking in dust-containing air and an inlet / outlet for taking in and out the dust collecting case. In addition, the vacuum cleaner main body is provided with a closing means for closing the main body intake port in a state where the dust collection case is taken out from the dust collection case chamber through the entrance and exit. In the state where it is taken out from the dust collection case chamber, the packing can be placed in contact with the opening edge of the inlet / outlet and installed at the inlet / outlet. Dust The installed casing in a state of opening the cover member, by the suction force when said electric blower is driven, characterized in that the dust collecting filter paper so as to close contact with the dust container.
According to this vacuum cleaner, the dust case has a packing at the downstream side in the dust suction direction, and the dust collection case is brought into contact with the opening edge of the entrance and exit of the dust collection case chamber via the packing. Since the main body inlet is closed by the closing means, the dust collecting filter paper can be sucked into the dust container by using the suction force driven by the electric blower. It can be closely attached inside.

Inside the vacuum cleaner main body 2, an electric blower 2A for generating a suction force, a dust collection case 10 (see FIG. 2) for collecting dust sucked by the suction force of the electric blower 2A, and the like are incorporated. The operation level of the electric blower 2A can be switched by operating a hand operation switch SW provided on the operation tube 4 or the like.
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 2a is provided on the upper surface of the vacuum cleaner main body 2. By opening the lid 2a, a dust collection case chamber 2b in which the dust collection case 10 is accommodated is provided. It is supposed to be exposed. The dust collection case 10 is provided detachably with respect to the dust collection case chamber 2b, and is periodically taken out from the dust collection case chamber 2b after completion of cleaning or the like. And the dust collected inside the dust collection case 10 is thrown away to a trash box etc. The dust collection case chamber 2 b is formed on the front side inside the cleaner body 2, and the electric blower 2 </ b> A is arranged on the rear side inside the cleaner body 2.

  The lid 2a is opened when the dust collecting case 10 is put in and out or when a disposable dust collecting filter paper such as a tissue paper T (see FIG. 10) described later is attached, and is closed during the cleaning operation. . The attaching / detaching direction of the dust collecting case 10 with respect to the dust collecting case chamber 2b is substantially vertical, and when the dust collecting case 10 is accommodated in the dust collecting case chamber 2b, a lid member 12 to be described later is disposed on the front side. The dust collection case 10 is inserted into the dust collection case chamber 2b so as to face the surface.

  In addition, a drive switch S for directly driving the electric blower 2A on the cleaner body 2 side is provided on the upper surface of the cleaner body 2. As will be described later, the drive switch S is turned on and off when the tissue paper T (see FIG. 10) is attached to the dust container 13 of the dust collection case 10.

  A main body inlet 2c through which the sucked dust enters through the hose 3 (refer to FIG. 1) is provided on the upstream side of the dust collection case chamber 2b. The main body inlet 2c is provided with an inlet 12a formed in a lid member 12 of a dust collecting case 10 to be described later and an opening packing 12c for ensuring airtightness. A partition wall 9 that partitions the dust collection case chamber 2b and the electric blower chamber 8 (see FIG. 10) in which the electric blower 2A is disposed is formed on the downstream side in the dust suction direction of the dust collection case chamber 2b. The partition wall 9 is formed with a communication port 2e that allows the dust collection case chamber 2b and the electric blower chamber 8 to communicate with each other.

The entrance / exit 20 of the dust collection case chamber 2b is opened in a substantially square shape so that the dust collection case 10 can be taken in and out, and the entrance / exit 20 has four opening edges 21 to 24 as shown in FIG. Is provided. A packing 18 (see FIG. 7) provided on the rear surface of the filter member 15 (see FIG. 7) (especially on the rear surface side of the frame body) can come into contact with these opening edges 21 to 24 over substantially the entire circumference. (The portion indicated by hatching in FIG. 3B). That is, the partition wall airtight surface 9a (see FIG. 5) of the partition wall 9 described later and the airtight surface formed by these opening edges 21 to 24 have substantially the same shape (see FIG. 3B). . As a result, as shown in FIG. 9, the dust collection case 10 can be placed at the entrance / exit 20 with the rear surface (packing 18) facing down. Therefore, the shape of the opening edges 21 to 24 of the entrance / exit 20 of the dust collection case chamber 2 b corresponds to (for example, matches) the shape of the opening edge of the rear opening of the dust collection case 10. For example, if the shape of the opening edge of the rear opening of the dust collection case 10 is a flat, substantially square shape, the shape of the opening edges 21 to 24 of the entrance / exit 20 of the dust collection case chamber 2b is preferably a flat, substantially square shape.
In addition, as shown in FIG. 2, the entrance / exit 20 is formed in the downward inclination shape from the partition wall 9 side toward the main body inlet 2c side. That is, when the height of the opening edge 21 on the partition wall 9 side in the entrance / exit 20 is compared with the height of the opening edge 24 on the main body inlet 2c side, the opening edge 21 on the partition wall 9 side is located at a higher place.

  As shown in FIG. 3A, the opening edge 21 forms the rear edge of the entrance / exit 20, and the upper portion of the packing 18 (see FIG. 3B) is brought into contact therewith. A notch 21 a is formed behind the opening edge 21. As shown in FIG. 10, the notch portion 21 a is a positioning portion of a locking portion 16, which will be described later, provided on the upper portion of the case member 11 of the dust collection case 10 when the dust collection case 10 is placed at the entrance / exit 20. And it functions as an escape portion of the locking portion 16.

  As shown in FIG. 3A, the opening edges 22 and 23 form left and right edges of the entrance / exit 20, and the left and right side portions of the packing 18 (see FIG. 3B) are in contact with each other. The opening edges 22 and 23 are narrower on the rear side than the front side, and the entrance / exit 20 is widened. In this embodiment, the wide part 11g (refer FIG. 2) of the rear part of the case member 11 is penetrated between these parts 22a and 23a. Note that a slight gap is formed between the portions 22a and 23a and the packing 18, but since the ratio of the gap is small, the tissue paper T (FIG. 10) is driven by the electric blower 2A described later. This does not affect the suction force when wearing the device.

The opening edge 24 forms the front edge of the entrance / exit 20, and the lower side portion of the packing 18 (see FIG. 3B) is brought into contact therewith.
In addition, it is not necessary to provide all the opening edges 21 to 24, and at least two of them may be provided at the entrance / exit 20. For example, only the opening edge 21 and the opening edge 24 may be provided, or only the opening edge 22 and the opening edge 23 may be provided.
Positioning ribs 25 and 26 project from the sides of the opening edges 22 and 23 so as to surround the doorway 20 from the left and right sides.

Further, a closing member 30 as a closing means is provided in the dust collection case chamber 2b. The closing member 30 is a member for closing the main body inlet 2c, and includes a rotating shaft 31, an arm portion 32, a lid portion 33, and a guide piece 34 as shown in FIG.
The rotation shaft 31 is rotatably supported by a receiving portion 2h (see FIG. 10) provided at the bottom of the dust collection case chamber 2b (see FIG. 11). The lid portion 33 provided from the rotating shaft 31 via the arm portion 32 has a circular shape when viewed from the front, and comes into contact with the downstream opening of the main body inlet 2c as shown in FIG. The main body inlet 2c is formed in a size for closing.

As shown in FIG. 4, the guide piece 34 is provided at the upper end of the lid portion 33, and is formed in a curved inclined shape from the lid portion 33 toward the rear upper side. The guide piece 34 is provided at a position corresponding to the lower surface of the dust collecting case 10 inserted into the dust collecting case chamber 2b (see FIGS. 11 and 12), and is in contact with the lower surface of the dust collecting case 10. It comes to be pressed.
The inclination angle of the guide piece 34 is desirably 30 to 70 ° with respect to the insertion direction of the dust collecting case 10. Further, as shown in FIG. 14, the guide piece 34 is a recess of the cleaner body 2 provided to accommodate the front wheel portion 40 when the closing member 30 is located on the bottom surface of the dust collecting case chamber 2b. The angle is along the surface of 41 of the dust collection case chamber 2b. By adopting such a shape, it can be accommodated with a protrusion corresponding to the wall thickness of the closing member 30, so there is no wasted space and the vacuum cleaner body 2 does not have to be enlarged.

As shown in FIG. 10, such a closing member 30 is held in an upright posture in the dust collection case chamber 2 b by an urging spring 35 attached to the rotating shaft 31, and in this posture, the lid The portion 33 is configured to block the main body inlet 2c. Further, as will be described later, when the guide piece 34 is pressed against the lower surface of the dust collecting case 10 inserted into the dust collecting case chamber 2b, the guide piece 34 rotates from the upright position toward the bottom surface of the dust collecting case chamber 2b. However, the weight of the dust collection case 10 pushes down the bottom surface of the dust collection case chamber 2b (see FIG. 14).
That is, when the dust collection case 10 is taken out from the dust collection case chamber 2b, the main body inlet 2c is blocked by the closing member 30, and the dust collection case 10 is accommodated in the dust collection case chamber 2b. In the state, the main body inlet 2c is opened.
In order to enable such an operation of the closing member 30, the biasing force of the biasing spring 35 is set to be smaller than the gravity applied to the dust collection case 10.

  Further, as shown in FIG. 5, the partition wall 9 provided in the dust collection case chamber 2b has a frame shape in which the packing 18 at the rear end of the dust collection case 10 accommodated in the dust collection case chamber 2b is in close contact. It has the partition wall airtight surface 9a. Here, the hatched portion in FIG. 5 is an airtight surface between the partition wall 9 and the packing 18. In the present embodiment, the airtight surface between the opening edges 21 to 24 (see FIG. 3B) of the entrance / exit 20 and the packing 18 is substantially the same as the airtight surface between the partition wall 9 and the packing 18. .

Referring again to FIG. 2, the dust collection case 10 includes a cylindrical case member 11 and a lid member 12 that is rotatably provided at the front portion of the case member 11. And a dust container 13 having a mesh-like filter 13a for separating air and dust. Further, a filter member 15 (see FIG. 7) is provided at the rear portion of the case member 11. The front opening (opening 11d) 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 (see FIG. 7).
In the present embodiment, as will be described later, a tissue paper T functioning as a disposable dust collecting filter paper (see FIG. 10) is provided at the front opening of the dust container 13 on the upstream side in the dust suction direction of the dust container 13. The same applies hereinafter), and the interposed tissue paper T is configured to be sandwiched between the case member 11 and the lid member 12.
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.

As shown in FIG. 2, an operation button 11 c is provided at the upper front end of the case member 11. The operation button 11c is provided so as to be swingable about a support shaft portion (not shown) that protrudes from the left and right at a substantially central portion, and the front end is pushed by pushing the pressing operation portion 11h provided at the rear end with a finger. The hook portion 11e provided on the side is disengaged from the engaging portion 12e provided at the upper front end of the lid member 12, so that the lid member 12 is opened.
Further, the case member 11 has a handle 14 extending in the front-rear direction at an upper portion thereof.

  The lid member 12 is rotatably provided around a hinge portion 11a provided at the lower front end of the case member 11, and is rotated so as to fall forward by operating the operation button 11c. 11 openings 11d are opened. And the dust container 13 protrudes through the opening part 11d in the state by which the cover member 12 was opened. In addition, the rear side of the dust container 13 is located in the dust collection case 10 in a state where the dust container 13 protrudes from the opening 11d. However, the rear side of the dust container 13 may be located outside the dust collection case 10 in a state where the dust container 13 protrudes from the opening 11d. That is, the entire dust container 13 may be located outside the dust collection case 10 with the dust container 13 protruding from the opening 11d. Further, the lid member 12 can be rotated around a hinge portion (not shown) provided at the upper front end of the case member 11 instead of being provided around the hinge portion 11 a provided at the lower front end of the case member 11. May be provided.

  A circular inflow port (suction port) 12 a (see FIG. 2) is formed in the center of the lid member 12. The inlet 12a communicates with the hose 3 (see FIG. 1), and air containing dust flows into the dust collecting case 10 through the inlet 12a. The inlet 12a is provided with a check valve 12b that closes the opening of the inlet 12a. The check valve 12b is preferably made of an elastic material such as synthetic rubber. The check valve 12b closes the opening of the inlet 12a so that dust accumulated in the dust container 13 does not spill from the inlet 12a. When the air does not flow in from the inlet 12a, the check valve 12b closes the opening of the inlet 12a. When the air flows in from the inlet 12a, the check valve 12b It is elastically deformed to the downstream side, that is, the inner side of the dust collecting case 10 against the elastic force. Accordingly, the inlet 12a is opened in a state where air flows from the inlet 12a.

  The dust container 13 (dust collecting basket, ventilation member) is disposed in the case member 11 and has a mesh-like filter 13a that collects large coarse dust. The shape of the dust container 13 is formed by a frame body (branch), and the filter 13a is provided on a surface other than the opening of the dust container 13, and the filter 13a made of metal or nylon is covered or covered. It is preferable that it is stuck.

The dust container 13 has a container shape in which an upper container 13A and a lower container 13B, which are divided into upper and lower parts, are connected via a rear hinge 13C (see FIG. 6), the front side is open and the back side is closed. (The upstream side in the air flow direction is open and the downstream side is closed). The dust container 13 has a bottom portion that is downstream in the dust suction direction, and is recessed in an arc shape toward the downstream side (the opening side of the case member 11 (the filter member 15 in the case member 11 is disposed). (Opening side) to be recessed, see FIG.

The shape of the dust container 13 may be a cage shape, a three-dimensional shape, a box shape, a container shape, or a dustpan shape. The cross-sectional shape of the dust container 13 may be a substantially semicircular shape, or may be a substantially triangular shape in which the bottom (downstream) side has an arc shape. In any case, the cross-sectional shape of the dust container 13 is preferably a shape in which a tissue paper T, which will be described later, is easily adhered to the inner surface, and the cross-section becomes smaller from the opening toward the bottom surface.
A tissue paper T is arranged in close contact with the inside of the dust container 13 along the inner wall surface (filter 13a).

As shown in FIG. 6, the dust container 13 has a base portion 13D attached to the bottom surface of the case member 11, and via a spring member 17 attached between the base portion 13D and the lower container 13B. The base 13D is rotatably supported. The spring member 17 urges the dust container 13 in a direction in which the dust container 13 is pushed out toward the opening 11 d of the case member 11. However, the spring member 17 is not an essential configuration. When there is no spring member 17, the dust container 13 protrudes from the case member 11 due to gravity.
The lower container 13B is provided so as to be rotatable with respect to the base portion 13D via a support shaft (not shown) provided at the left and right lower portions of the lower container 13B.
The dust container 13 can be detached from the case member 11 integrally with the base portion 13D. Therefore, it can be easily cleaned. When it is desired to wash the dust container 13 with water, it can be easily washed with the case 11 removed from the case member 11, and the drying time is relatively short.

As shown in FIG. 8A, a restriction stopper 13f for restricting the rotation of the dust container 13 is provided on the upper portion of the upper container 13A. The restriction stopper 13f comes into contact with a restriction portion 11f provided on the upper inner wall of the case member 11. That is, the restricting portion 11f is positioned on the turning locus of the restricting stopper 13f when the dust container 13 is pushed out toward the opening 11d (see FIG. 2) of the case member 11.
As a result, when the dust container 13 is rotated in a direction in which the dust container 13 is protruded by the urging force of the spring member 17 (see FIG. 6), as shown in FIGS. 8A and 8B, the restriction stopper 13f is moved to the restriction portion 11f. The rotation is restricted by contact, and finally, the upper container 13A and the lower container 13B are opened in the vertical direction with the hinge 13C as a fulcrum, and the rotation is restricted. That is, the dust container 13 is rotated (projected) and opened in a direction opposite to the direction of air flow when collecting dust, whereby the dust container 13 is opened. The dust collected inside can be easily thrown away into a trash can.

Here, the light and fluffy fiber dust such as cotton dust collected in the dust container 13 is likely to be compressed and compressed by the air flow passing through the dust container 13. Part of the fine dust that has flowed into the dust container 13 is also collected by the fiber dust that has been compressed and solidified in the dust container 13. When the operation of the vacuum cleaner 1 is stopped, the compressed dust lump loses the compressive force due to the air flow, the compressed dust lump spreads, and the dust lump volume increases.
However, the dust container 13 extends toward the opening, and when the accumulated dust is thrown away, the upper container 13A and the lower container 13B are opened so as to expand the opening. Therefore, the dust container 13 is compressed in the dust container 13. Even when the lump of dust spreads, it can be easily discharged.
At this time, the dust sucked into the dust container 13 is easily compressed into a lump due to the air flow, and is discharged in a lump when discharged from the dust container 13 through the opening. The provided mesh-like filter 13a is less likely to be clogged with less dust adhesion and entanglement. For this reason, it is possible to prevent the trouble of removing the dust from the filter 13a only by throwing away the dust accumulated in the dust container 13.

As shown in FIG. 6, the filter member 15 provided in the rear part of the case member 11 has, for example, a shape corresponding to the opening edge of the rear opening of the case member 11 (opening communicating with the communication port 2e to the electric blower 2A). And a filter 15b that is formed in the frame and has a corrugated pleat process, and is provided so as to be openable and closable with respect to the case member 11 by a hinge 15a provided at a lower portion of the case member 11. Therefore, the rear opening of the dust collecting case 10 is formed by the frame body of the filter member 15, and the inside of the frame body is closed by the filter 15b so as to allow ventilation. Usually, the filter member 15 is locked in a closed state by a hook of a locking portion 16 provided on the upper portion of the case member 11.
The filter member 15 is configured to filter and collect fine fine dust that has passed through the dust container 13. Therefore, the opening of the filter 13 a of the dust container 13 is coarser (larger) than the opening of the filter 15 b of the filter member 15.

Next, the action when the dust collected in the dust container 13 is discarded and then the dust container 13 is housed in the dust collecting case chamber 2b of the cleaner body 2 will be described with reference to each drawing as appropriate.
When the dust is thrown into a trash box or the like, the handle 14 of the dust collection case 10 is grasped, the dust collection case 10 is taken out from the dust collection case chamber 2b of the cleaner body 2 (see FIG. 11), and the operation button 11c is pressed. The part 11h (see FIG. 2) is pressed. If it does so, the hook part 11e will remove | deviate from the latching | locking part 12e of the cover member 12, and the cover member 12 will be opened. At this time, the lid member 12 is pressed forward by the dust container 13 urged by the spring member 17 and pivoted about the hinge portion 11a (see FIG. 2). At the same time, the dust container 13 protruded forward by the spring member 17 is restricted in rotation by the restriction stopper 13f coming into contact with the restriction portion 11f (see FIGS. 8A and 8B) and vertically. The divided upper container 13A and lower container 13B are opened in the vertical direction via the rear hinge 13C. As a result, the dust collected inside the dust container 13 is thrown forward together with the tissue paper T housed inside as will be described later, and the dust is discharged.

  Further, when the dust collecting case 10 is taken out from the dust collecting case chamber 2b, as shown in FIG. 11, the closing member 30 arranged on the bottom surface of the dust collecting case chamber 2b is raised by the biasing spring 35, and the lid is covered by the biasing force. The portion 33 closes the main body inlet 2c.

After the dust is discharged, as shown in FIG. 10, with the lid member 12 open, the opening 11d of the case member 11 faces upward (the packing 18 at the rear end of the dust collecting case 10 is directed downward). The dust collecting case 10 is placed on the opening edges 21 to 24 (see FIG. 3A) so as to cover the entrance / exit 20 of the cleaner body 2.
Then, the tissue paper T is placed on the opening of the dust container 13, the dust container 13 is pushed toward the case member 11, and one end of the tissue paper T is sandwiched between the hook portion 11e of the operation button 11c and the upper container 13A. In this manner, the upper edge of the upper container 13A is hooked on the hook portion 11e.

  In this state, the drive switch S (see FIG. 2) provided on the upper surface of the cleaner body 2 is turned on. Then, the electric blower 2A of the cleaner body 2 is driven, and the air in the dust collection case chamber 2b is sucked into the electric blower 2A across the partition wall 9. At this time, since the main body inlet 2c is closed by the lid portion 33 of the closing member 30, the intake air flows into the dust collecting case chamber 2b through the dust collecting case 10 placed at the entrance / exit 20.

Then, the tissue paper T placed in the opening of the dust container 13 of the dust collecting case 10 is sucked toward the inside of the dust container 13 and arranged while closely adhering along the inner surface (filter 13a) of the dust container 13. It is done.
Therefore, the flat tissue paper T can be disposed in close contact with the inner surface of the dust container 13. Therefore, the tissue paper T can be suitably mounted in the dust container 13, and the tissue paper T can be prevented from being broken during dust suction.

In this state, the lid member 12 is rotated and closed, and the tissue paper T is sandwiched between the case member 11 and the lid member 12. And the drive switch S provided in the upper surface of the cleaner body 2 is turned off, and the electric blower 2A is stopped.
Then, the dust collection case 10 is removed from the entrance / exit 20, and this is accommodated in the dust collection case chamber 2b. At this time, as shown in FIG. 12, when the lower surface of the dust collection case 10 is inserted into the dust collection case chamber 2b through the doorway 20, the lower surface of the dust collection case 10 comes into contact with the guide piece 34 of the closing member 30. By pressing, the closing member 30 starts to rotate backward.

  Thereafter, as illustrated in FIG. 13, when the dust collection case 10 is further inserted into the dust collection case chamber 2 b, the guide piece 34 of the closing member 30 is further pressed by the lower surface of the dust collection case 10. Then, as shown in FIG. 14, when the dust collection case 10 is completely accommodated in the dust collection case chamber 2b, the closing member 30 falls to the bottom surface of the dust collection case chamber 2b, and the main body intake port 2c and the inflow port 12a of the cover member 12 communicate.

Thereafter, when the electric vacuum cleaner 1 is operated for cleaning, most of the dust sucked into the dust container 13 accumulates on the tissue paper T disposed in the dust container 13 and the upstream side thereof. In this case, the dust sucked into the dust container 13 tends to become a mass compressed by the air flow, and thus is in a state of being wrapped in the tissue paper T in the upstream region of the dust container 13.
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.

  Fine dust that has passed through the filter 13 a of the dust container 13 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. Fine dust accumulated in the lower portion can be discharged from the front side of the dust container 13 through a passage (not shown) formed between the base portion 13 </ b> D and the case member 11.

The operational effects of this embodiment will be described below.
(1) According to the vacuum cleaner 1 of the present embodiment, the packing 18 of the dust collecting case 10 can be placed in contact with the opening edges 21 to 24 of the entrance / exit 20 of the cleaner body 2, and the lid member 12. Since the tissue paper T can be brought into close contact with the inner surface of the dust container 13 by the suction force when the electric blower 2A is driven in a state where the electric blower is opened, the tissue paper T is preferably disposed in the dust container 13 can do. Therefore, the dust collected in the dust collection case 10 can be easily discharged, and the maintenance work of the filter 13a (filter member 15) provided in the dust collection case 10 can be reduced.
(2) At the time of sucking the tissue paper T, the suction force acts evenly on the entire filter 13a, so that it is easy to adhere to the whole as compared with a method of pressing a part with a rib or the like. Further, when the tissue paper T is pushed in by hand, there is a case where it is unclear how much the paper is pushed in. However, in this embodiment, the tissue paper T is uniformly adhered to the inner surface of the dust container 13 without being lost. It is easy to use.
(3) Since the tissue paper T is sandwiched between the case member 11 and the lid member 12 when the lid member 12 is closed while the tissue paper T is stuck to the dust container 13, the tissue paper T is kept in close contact. In addition, the clamping operation can be easily performed.
(4) Since the dust collecting case 10 can be brought into close contact with the entrance / exit 20 using the packing 18 provided in the dust collecting case 10, no separate parts for close contact by suction are required, and the large size of the vacuum cleaner main body 2 can be obtained. The tissue paper T can be suitably disposed in the dust container 13 without increasing the number of parts or the number of parts.
(5) Since the partition wall airtight surface 9a and the airtight surface of the entrance / exit 20 formed of the opening edges 21 to 24 have substantially the same shape, one type of packing 18 may be provided in the dust container 13, and these airtights Compared with the case where the packing has two kinds of shapes so as to correspond to the surface, the configuration is simpler, thereby preventing the vacuum cleaner body 2 and the dust collecting case 10 from being enlarged.
(6) Since the tissue paper T can be attached to the inside of the dust container 13 without a gap by a suction force, even if a large amount of dust is sucked in, the tissue paper T is not easily torn and the tissue paper T is torn. The life of the filter member 15 can be improved as compared with the above.
(7) When placing the tissue paper T, the tissue paper T can be sandwiched between the dust container 13 (upper end portion of the upper container 13A) and the hook portion 11e of the operation button 11c. Can be suitably positioned. Therefore, it is possible to prevent the tissue paper T from being displaced due to wind or the like, and there is an advantage that attachment is easy. Moreover, the tissue paper T can be prepared and attached neatly.
(8) The dust container 13 has a bottom portion that is downstream in the dust suction direction, and is recessed in an arc shape toward the downstream side, so that, for example, compared to a case where the bottom portion is formed in a square shape or the like. The tissue paper T can be brought into close contact with the inner surface of the dust container 13 without any gaps, and is more difficult to tear.
(9) Since the dust container 13 is rotated and opened in a direction opposite to the direction of air flow when collecting dust, the dust container 13 is collected in the dust container 13. Dust can be easily thrown away into a trash can. Since the tissue paper T is disposed on the upstream side of the dust container 13 as a disposable dust collecting filter paper, the filter 13a of the dust container 13 and the filter member 15 at the rear of the dust collecting case 10 are clogged. Can be suppressed. Further, since the collected dust tends to become a mass compressed by the air flow, it is in a state of being wrapped in the tissue paper T upstream of the dust container 13, and most of the dust is discharged when the dust is discharged. It is discharged in the form of a lump wrapped in paper T. Therefore, it does not cause fine dust soot and is hygienic.
(10) Since the entrance / exit 20 is formed so as to be inclined downward from the partition wall 9 side toward the main body inlet 2c side, the opening 11d of the dust container 13 faces the user and the tissue paper T is attached. easy.

  FIG. 15 is a perspective view showing a vacuum cleaner body according to a modified vacuum cleaner, and FIG. 16 is a perspective view showing a state in which a front wall portion of the vacuum cleaner body is opened.

In such a configuration, when the tissue paper T is mounted, the front wall portion 51 is rotated to expose the lid member 12 of the dust collecting case 10. Then, the operation button 11 c is operated to open the lid member 12, the dust container 13 is protruded, and the tissue paper T is applied from the front side of the dust container 13.
Thereafter, the drive switch S is turned on to drive the electric blower 2A, and the tissue paper T is attached to the inside of the dust container 13 by the suction force. When the attachment is completed, the lid member 12 is closed, the tissue paper T is sandwiched between the case member 11 and the lid member 12, and the drive switch S is turned off.
Thereafter, the front wall 51 is rotated and closed.

  According to such a configuration, the tissue paper T can be attached while the dust collecting case 10 is stored in the dust collecting case chamber 2b, and the trouble of taking out the dust container 13 one by one becomes unnecessary. , It improves usability.

It is formed in a curved shape corresponding to the lower frame body 13j, and is provided so as to be able to contact or detach from the frame body 13j by rotation. And the holding member 60 can clamp the tissue paper T between the frame bodies 13j.

Here, the frame 13j at the lower front end of the lower container 13B is recessed rearward with the step 13k as a boundary. As shown by a two-dot chain line in FIG. 18, the holding member 60 contacts the frame 13j. In the state of contact, the front surface of the holding member 60 is configured to be flush with the front surface of the adjacent frame portion 13m. As a result, the lid member 12 is in a state in which the lid member 12 is preferably in close contact with the front surface of the holding member 60 and the frame portion 13m of the lower container 13B while being closed with respect to the case member 11, thereby providing airtightness. The tissue paper T is configured to be held.
The holding member 60 may be provided on the upper container 13A side.

When sandwiching the tissue paper T using such a restraining member 60, as shown in FIG. 19, the tissue paper T is applied to the opening of the dust container 13, and one end thereof is restrained between the restraining member 60 and the frame body 13j. Between them.
Then, the drive switch S (not shown in FIG. 19, not shown below) is turned ON to drive the electric blower 2A, and the tissue paper T is attached to the inside of the dust container 13 by the suction force. When the attachment is completed, the lid member 12 is closed, the tissue paper T is sandwiched between the case member 11 and the lid member 12, and the drive switch S is turned off.
