Further, the main body portion 10 is provided with a tube portion 38x having a suction port 38y for connecting an extension tube 180 or a suction tool 190. The suction port 38y is formed to open at the lower end side (one side in the first direction) of the main body portion 10. Moreover, the pipe part 38x is arranged so as to be aligned with the first dust collection part 50 in a second direction that intersects with the first direction.

The first dust collecting part 50 is a part where the dust sucked by the vacuum cleaner 1 is collected. The first dust collection section 50 is provided so as to be continuous with the main body section 10. Specifically, the first dust collection section 50 is arranged in a direction perpendicular to the axial direction (first direction) of the main body section 10 so as to be lined up with the tube section 38x. Since the first dust collecting section 50 has a characteristic configuration in the vacuum cleaner 1, the specific structure will be described in detail later.

The extension tube 180 is a cylindrical member that detachably connects the main body 10 and the suction tool 190. The extension tube 180 has a shape that allows one end to be inserted into the suction port 38y provided in the main body 10, and a shape that allows the other end to be connected to the suction tool 190. By connecting the main body 10 and the suction device 190 via the extension pipe 180, a series of communicating paths (air paths) from the suction device 190 to the main body 10 can be formed.

The suction tool 190 is connected directly to the suction port 38y of the main body 10 or indirectly via the extension pipe 180. The suction tool 190 has a suction port 192 and a joint portion 194.

The vacuum cleaner 1 has roughly the above-described configuration. The vacuum cleaner 1 is characterized by the layout of its constituent parts, the structure of the handle part 16 and the first dust collecting part 50, and the like. Below, these characteristic configurations will be explained in more detail.

≪About the configuration of the handle part 16≫
Although the main body part 10 is formed so that the main body case 12 extends toward one side (downward side in FIG. 1) in the first direction (vertical direction in FIG. 1; longitudinal direction of the vacuum cleaner 1). On the other hand, the handle portion 16 is formed to extend toward the other side in the first direction (the upper side in FIG. 1). As shown in FIGS. 1 to 4, the handle portion 16 includes a first extending portion 16a, a second extending portion 16b, a curved portion 16c, and an operating portion 16e. An opening 16d is formed between the main body part 10 (main body case 12) and the handle part 16.

The first extending portion 16a is a portion of the handle portion 16 that extends in the first direction. The first extending portion 16a extends in the first direction from the other side (the upper side in the illustrated example) of the first electric blower 14. The size of the first extending portion 16a can be set as appropriate, but in this embodiment, the size is set in a range of 6 cm or more and 10 cm or less in consideration of ease of gripping and the like.

The second extending portion 16b is a portion extending in a second direction (horizontal direction in the illustrated example) orthogonal to the first direction. Similarly to the first stretched part 16a, the second stretched part 16b can have an appropriate size, but in this embodiment, the size is set in the range of 6 cm or more and 10 cm or less in consideration of ease of grasping. It is said to be the size. Furthermore, in the present embodiment, the second extending portion 16b has the same size as the first extending portion 16a. Thereby, the handle portion 16 can be used with the same feeling even when gripping either the first extending portion 16a or the second extending portion 16b.

The curved portion 16c is a curved portion that connects the first extending portion 16a and the second extending portion 16b. By providing the curved portion 16c, the handle portion 16 has a curved boundary portion between the first extending portion 16a and the second extending portion 16b, and a step etc. from the first extending portion 16a to the second extending portion 16b. It is said to be a continuous, connected shape. As a result, by sliding your hand along the handle portion 16 while grasping one of the first extending portion 16a and the second extending portion 16b, the first extending portion 16a and the second extending portion 16b can be moved. The gripping position can be changed to the other side of 16b. That is, the gripping form of the handle portion 16 can be changed without removing the hand.

The opening 16d is an opening area formed between the first extending portion 16a, the second extending portion 16b, and the curved portion 16c, and the main body case 12 in the handle portion 16. The opening 16d can be used to insert a hand when gripping the handle portion 16. The opening 16d is located on the other side (upper side in FIG. 1) than the first electric blower 14 in the first direction (vertical direction in FIG. 1).

The operation unit 16e is provided for operating the vacuum cleaner 1 and the like. The operation unit 16e may include various switches and the like. The operating portion 16e may be provided on any of the first extending portion 16a, the second extending portion 16b, and the curved portion 16c, but in this embodiment, the operating portion 16e is provided on the first extending portion 16e, which is likely to be gripped in normal usage. It is provided in the extending portion 16a. The operating portion 16e may be provided anywhere in the portion forming the first extending portion 16a. In this embodiment, the operating portion 16e is provided on a surface facing away from the opening 16d so that it can be easily operated with the thumb during use.

≪About battery 15a≫
The battery 15a is arranged in a direction (second direction) perpendicular to the axial direction of the main body 10 so as to be lined up with the first electric blower 14. In other words, the first electric blower 14 and the battery housing section 15 are arranged in a direction (second direction) perpendicular to the axial direction (first direction) of the main body section 10 . Furthermore, when viewed from the first direction, the battery 15a is arranged so as to overlap the first dust collecting section 50 at least in part.

<<About the control unit 17>>
The control unit 17 is disposed inside the main body 10 on the opposite side of the battery 15a with respect to the first electric blower 14. That is, the control unit 17 is arranged on one side of the first electric blower 14 in the second direction (the front side of the vacuum cleaner 1), and the battery 15a is arranged on the other side of the first electric blower 14 in the second direction. (on the back side of the vacuum cleaner 1). The control section 17 exists within the projection area of the tube section 38x (the suction port 38y) forming the main body section 10 in the first direction. Further, the control section 17 is disposed in a region on the other side (lower side in FIG. 1) of the opening 16d of the handle section 16 in the first direction.

≪About the first electric blower 14≫
As shown in FIGS. 4 to 6, the first electric blower 14 is housed inside the main body 10 while being covered by a case body 14a. The case body 14a includes an exhaust opening 14x on the peripheral surface 14b. The exhaust opening 14x is arranged in a horizontal direction intersecting the first direction (vertical direction) and in a third direction (horizontal direction of the vacuum cleaner 1) orthogonal to the second direction (the longitudinal direction of the vacuum cleaner 1). (in the illustrated example, toward the right side of the vacuum cleaner 1). On the other hand, the external exhaust opening 10x provided on the outer circumference of the main body portion 10 is provided on the other side in the third direction (in the illustrated example, toward the left side of the vacuum cleaner 1). That is, the exhaust opening 14x provided in the case body 14a is provided on the opposite side in the third direction to the external exhaust opening 10x provided in the main body 10.

Further, as described above, the control unit 17 is provided at a position away from the first electric blower 14 in the second direction (the front-rear direction of the vacuum cleaner 1). That is, the control section 17 is provided at a position separated from the exhaust opening 14x by a predetermined amount (approximately 90 degrees in this embodiment) in the circumferential direction. Further, an external exhaust opening 10x is provided at a position further away from the control unit 17 by a predetermined amount (approximately 90 degrees in this embodiment) in the circumferential direction. Therefore, the control unit 17 is arranged in the middle of the path from the exhaust opening 14x to the external exhaust opening 10x. Thereby, the exhaust air discharged from the first electric blower 14 is exhausted to the outside of the main body section 10 through a path passing through the control section 17 . Further, the exhaust opening 14x and the external exhaust opening 10x may be arranged so as to overlap at least in part when viewed from the third direction, or may be offset from each other.

In addition, the first electric blower 14 has a central axis that extends in the first direction of the first dust collecting section 50 (the longitudinal direction of the vacuum cleaner 1; the vertical direction in the attitude shown in FIG. 1). As a reference, the battery 15a is located at a position opposite to the side where the battery 15a is present in a second direction (horizontal direction in the orientation shown in FIG. 1) intersecting the first direction.

≪About the configuration of the first dust collection section 50≫
The first dust collecting section 50 will be described in detail below with reference to FIGS. 1 to 3, FIGS. 7 to 14, and the like. The first dust collection section 50 is provided in a detachable manner with respect to the main body section 10. The first dust collecting section 50 is a so-called cyclone type dust collecting device. That is, the first dust collection unit 50 operates the first electric blower 14 to introduce the sucked air into the first dust collection container 52, and after forming a swirling airflow within the first dust collection container 52, It is said to be able to collect dust contained in the air during the process of discharging the air. Further, the first dust collection section 50 can adopt a so-called single-stage or multi-stage separation system, but in this embodiment, a single-stage separation system is adopted.

As shown in FIGS. 1 to 3, the first dust collecting section 50 is arranged on one side (lower side) of the main body 10 in the first direction (the longitudinal direction of the vacuum cleaner 1). The first dust collection section 50 has a first dust collection container 52 (outer cylinder) and a structure 54, and a dust collection space 56 is formed between them. The first dust collection section 50 is capable of forming a swirling airflow in which the air introduced into the dust collection space 56 is swirled between the structure 54 and the first dust collection container 52 . The first dust collecting section 50 is removably attached to a position below the first electric blower 14 in the main body section 10 . For example, the first dust collecting section 50 may have a structure in which the bottom side is locked to the pipe part 38x, and the top side is provided with a lock button 52j for locking or unlocking with the main body case 12, or the bottom side is locked to the pipe part 38x. 38x and a lock button for locking or unlocking may be provided, and the upper side may be latched to the main body case 12.

As shown in FIGS. 7 to 9, etc., the first dust collection container 52 is a container for accumulating dust inside. The first dust collection container 52 is a hollow cylinder. As a result, the first dust collection section 50 includes a first dust collection chamber 52a that forms a dust collection space 56 inside the first dust collection container 52. The first dust collecting container 52 is open on the other side (upper side) in the axial direction. Moreover, the first dust collection container 52 has a waste port 52b and an opening/closing part 52c on the lower end side of the first dust collection chamber 52a.

The first dust collection container 52 has a waste port 52b (opening) on one side (lower side) in the axial direction. The disposal port 52b is an opening for allowing dust to be disposed of from the first dust collection chamber 52a. The waste port 52b opens at the lower end of the first dust collection chamber 52a. Moreover, the opening/closing part 52c can close the waste port 52b at the bottom of the first dust collection chamber 52a. Therefore, when the opening/closing part 52c is opened, the dust accumulated in the first dust collection chamber 52a can be disposed of through the disposal port 52b. A lid or a valve can be considered as an example of the opening/closing part 52c, but in this embodiment, the opening/closing part 52c is a lid that can close the waste port 52b. The opening/closing part 52c is connected to the first dust collection chamber 52a (the outer cylinder constituting the first dust collection container 52) so as to be rotatable about a rotation shaft 52e. The opening/closing portion 52c has a contact portion 52f in a region on one side of the rotation shaft 52e, and a closing portion 52g in a region on the other side.

The abutted portion 52f can be abutted by an abutting portion 152 provided on the receiving portion 130, which will be described in detail later. Further, the closing portion 52g is a portion that closes the waste port 52b. The opening/closing portion 52c is biased by a biasing member 52h (a torsion spring in this embodiment) at a portion closer to the abutted portion 52f than the rotating shaft 52e. Thereby, the closing portion 52g is biased in the direction of closing the waste port 52b. Further, the opening/closing portion 52c is closed by applying a force to the abutting portion 52f against the urging force of the urging member 52h, such as by abutting the abutting portion 152 against the abutting portion 52f. The waste port 52b can be opened by rotating the closing portion 52g so that the portion 52g moves away from the waste port 52b. Although the waste port 52b has an opening surface perpendicular to the axial direction of the first dust collecting container 52, it may have an opening surface inclined to the axial direction of the first dust collecting container 52. . For example, the opening surface of the waste port 52b may be inclined toward one side or the other side in the axial direction of the first dust collecting container 52 as it moves away from the rotating shaft 52e. This makes it easier for the dust in the first dust collection chamber 52a to form into lumps, making it easier for the dust collection device 100 to suction the dust.

In addition, although the structure which opens the opening-and-closing part 52c by the contact part 152 contact|abutting the to-be-contacted part 52f was demonstrated here as an example, it is not limited to this. That is, the structure is such that the urging member 52h is not biased, and as shown in FIG. 19, the opening/closing part 52c (closing part 52g) locks the waste port 52b of the first dust collection container 52 in a closed state. 52c (closed part 52g) or the first dust collecting container 52, and the opening/closing part 52c opens when the lock is released, and a contact part 152A that can come into contact with the lock part is provided on the contact part 152. Alternatively, it may be provided in the receiving part 130 so that the lock is released when the contact part 152A contacts the lock part. In this case, the lock portion has a contacted portion 52f1 that is contacted by the contact portion 152A. Note that, as shown in FIG. 19, it is preferable that the lock portion be configured to rotate around a rotation shaft. Although the rotation shaft 52e of the opening/closing part 52c is not shown in FIG. 19, it is located on the opposite side from the locking part.

In addition, on the premise that the opening/closing part 52c is biased by the biasing member 52h as described above, in addition to the configuration in which the abutting part 152 abuts the abutted part 52f, the opening/closing part 52c (the closing part 52g) is The receiving part 130 may be provided with a contact part 152A that can come into contact with a lock part that locks the waste port 52b of the first dust collection container 52 in a closed state. In this case, it is preferable that the abutting portion 152A abuts the lock portion (the abutted portion 52f1) before the abutting portion 152 abuts the abutted portion 52f. In this way, the opening/closing part 52c can be opened smoothly. On the other hand, when the opening/closing part 52c closes the waste port 52b, the contact part 152 separates from the opening/closing part 52c, and after the opening/closing part 52c closes the waste port 52b by force, the contact part 152A separates from the lock part. , it is preferable to lock the opening/closing part 52c. As such, it is preferable that the length of the contact portion 152A be appropriately designed to be longer than the contact portion 152. The closing portion 52g may be provided with an opening, and the closing portion 52g may be provided with a rotatable valve or a lid so that the opening can be opened and closed. In this case, the abutting portion 152 and the abutted portions 52f, 52f1 can mechanically perform the operation of opening the valve or lid described above.

As shown in FIG. 10, FIG. 11, etc., the first dust collection container 52 has a dust collection section inlet 52x (inflow port) on the periphery. The dust collecting section inlet 52x is a part that serves as an inlet for causing the air sucked into the air path formed inside the pipe section 38x from the suction port 38y to flow into the inside of the first dust collecting container 52. The dust collecting section inlet 52x is provided at a position corresponding to the opening provided at the end of the pipe section 38x, and is located, for example, in the middle of the first dust collecting container 52 in the first direction (axial direction). Therefore, by attaching the first dust collecting section 50 to the main body section 10, the dust collecting section inlet 52x and the air passage formed inside the pipe section 38x can be communicated with each other. Further, the dust collection section inlet 52x directs the air discharged from the air passage formed inside the pipe section 38x in the tangential direction of the inner peripheral surface of the first dust collection container 52 into the inside of the dust collection space 56. It is considered possible to introduce it. Therefore, the air introduced into the dust collection space 56 from the dust collection section inlet 52x forms a swirling flow that flows along the inner peripheral surface of the first dust collection container 52.

As shown in FIGS. 9 and 11, the structure 54 is a member disposed inside the first dust collection container 52. As shown in FIGS. The structure 54 is a member that constitutes a dust collection space 56 into which air flows between the structure 54 and the first dust collection container 52 . The structure 54 is arranged so that its axial center position substantially coincides with that of the first dust collecting container 52 . The structure 54 has a portion (tapered portion 70, which will be described later) whose outer shape decreases from one side (upper side in the figure) to the other side (lower side in the figure) in the axial direction. The structure 54 has a first inner cylinder 60 (inner cylinder) and one side cylinder part 64, and further includes a connecting body 62, although this is not an essential configuration. The first inner cylinder 60 is connected to the one side cylinder part 64, and when the connecting body 62 is provided, it is connected to at least one of the one side cylinder part 64 and the connecting body 62.

As shown in FIGS. 9, 12, 13, etc., the first inner cylinder 60 includes a tapered portion 70 and an extending portion 72. Further, the first inner cylinder 60 includes a first guide part 74 and a second guide part 76 on the outer circumference of the tapered part 70. Further, the first inner cylinder 60 is provided with a third guide portion 78 on the inner peripheral portion of the tapered portion 70, although this is not an essential configuration.

The tapered portion 70 is a portion formed such that the outer shape becomes smaller from one side (upper side in the figure) to the other side (lower side in the figure) in the axial direction. The tapered portion 70 is formed in the shape of a truncated cone, and is formed such that its outer circumferential surface slopes linearly toward the axial center as it goes from one side to the other side in the axial direction. The tapered portion 70 includes a closed portion 70a that is open toward one side (upper side) in the axial direction and closed on the other side (lower side) in the axial direction.

As shown in FIG. 9, the tapered portion 70 is formed such that the outer diameter of the large diameter portion 70b on one side in the axial direction substantially matches the inner diameter of the first dust collection container 52. As shown in FIG. Furthermore, a circumferential groove 70c extending in the circumferential direction is provided on the outer peripheral surface of the large diameter portion 70b. The tapered portion 70 seals the gap formed between it and the inner circumferential surface of the first dust collection container 52 by an airtight member (first airtight member 70d) made of an O-ring or the like attached to the circumferential groove 70c. A first sealing portion 73 can be formed. That is, by setting the tapered part 70 inside the first dust collecting container 52 with the closing part 70a facing the bottom side of the first dust collecting container 52, the first airtight member 70d attached to the circumferential groove 70c A first sealing portion 73 is formed in which the first dust collecting container 52 and the inner circumferential surface of the first dust collecting container 52 are in close contact with each other. Further, on the other side in the axial direction of the first sealing part 73 (bottom side of the first dust collecting container 52), dust is collected between the tapered part 70 (first inner cylinder 60) and the first dust collecting container 52. A space 56 is formed. Further, the first sealing part 73 is formed above the dust collecting part inlet 52x communicating with the dust collecting space 56.

In addition to the function of forming the dust collection space 56 as described above, the tapered part 70 also has a function as a dust collection space exhaust part 80 for exhausting air from the dust collection space 56. Specifically, the tapered portion 70 is provided with a large number of ventilation holes 70e in the circumferential direction, which are formed so as to communicate between the inside and the outside. The tapered portion 70 may be formed by resin molding or may be formed from a mesh member 82. The mesh member 82 is made of a resin material, a metal material, or a combination thereof. Therefore, the mesh member 82 can capture dust contained in the air passing through the ventilation hole 70e forming the dust collection space exhaust section 80. Since the surface of the tapered part 70 is smoother when the resin molding is used than the mesh member 82, it is possible to reduce the possibility of dust getting caught.

The extending portion 72 is a portion formed to further extend toward the other side in the axial direction from the tapered portion 70, but in this embodiment, the end portion on the other side in the axial direction (the lower end in the illustrated example) is the base end and the extending portion 72 extends along the axis. It extends toward the other side. The extending portion 72 is formed inside the dust collection space 56 so as to be spaced apart from the bottom of the first dust collection container 52 on one side in the axial direction (in the illustrated example, on the upper side). The extending portion 72 is formed so as to surround the periphery of the closing portion 70a. As a result, the extending portion 72 has a cylindrical shape whose upper end is closed by the closing portion 70a and whose lower end is open. Since the extending portion 72 is provided so as to surround the periphery of the closing portion 70a, the airflow and dust that have flown up from the bottom of the first dust collection container 52 at the position on the axis side of the dust collection space 56 are directed to the closing portion 70a. 70a and becomes difficult to spread in the direction crossing the axial direction. As a result, in the vacuum cleaner 1, dust such as hair and dust contained in the airflow is less likely to get entangled with the tapered portion 70. The extending portion 72 has a cylindrical shape. It is preferable that the extending portion 72 has a cylindrical shape having the same outer dimensions from the upper end to the lower end, or a tapered cylindrical shape whose outer diameter becomes smaller from the upper end to the lower end. This suppresses the airflow and dust that have been smoothly guided by the first guide portion 74 toward the other side in the axial direction (bottom side of the first dust collection container 52) from becoming entangled in the extension portion 72. can. Note that the extending portion 72 is not limited to a cylindrical shape, and may have a configuration in which a plurality of extending members extending in the axial direction are provided at intervals.

Further, the closing portion 70a may have a convex shape with the center side facing outward toward the bottom of the first dust collecting container 52, and more preferably may be curved. This makes it easier for the airflow and dust that have flown up from the bottom of the first dust collection container 52 at the position on the axis side of the dust collection space 56 to move toward the extension part 72 at the closing part 70a.

In addition, the first dust collecting container 52 is rotatably supported via a bottom integrally formed as the bottom of the first dust collecting container 52 or a support shaft provided around the first dust collecting container 52. A plurality of ribs (protrusions) 52d are provided on the bottom of the lid-shaped first dust collection container 52 that can be opened and closed to prevent dust from moving due to swirling airflow. good. The plurality of ribs 52i extend toward the structure 54 and are arranged at intervals in the circumferential direction. Further, as described above, the bottom integrally formed as the bottom of the first dust collection container 52 or the bottom of the first dust collection container 52 in the form of a lid that can be opened and closed has a plurality of ribs 52i. Alternatively, in addition to the plurality of ribs 52i, a protrusion extending toward the structure 54 (occluding portion 70a) may be provided. When a protrusion is provided together with the plurality of ribs 52i, the plurality of ribs 52i are arranged around the protrusion at intervals in a direction (radial direction in this embodiment) intersecting the axis. Further, the protruding portion is columnar, for example, a cylinder, a prism, a column with a cross section, or a column tapered toward the structure 54, a prism, or a column with a cross section. That's good. Thereby, it is possible to suppress the dust that collects below the closing portion 70a from moving due to the airflow. When the bottom of the first dust collection container 52 is formed into a lid-like structure that can be opened and closed by rotation, even if the dust gets entangled with the protrusion or the ribs 52i, it is easy to dispose of the dust.

As shown in FIGS. 12 and 13, the first guide portion 74 is a rib-shaped portion provided on the outer peripheral side of the tapered portion 70, and is in contact with the inner peripheral surface of the first dust collection container 52. As shown in FIGS. The first guide part 74 is configured to operate when the structure 54 is inserted into the first dust collecting container 52 with the tapered part 70 and the extending part 72 facing the bottom side of the first dust collecting container 52. It is arranged between the container 52 and the first inner cylinder 60. The first guide part 74 directs the airflow flowing into the dust collection space 56 from the dust collection part inlet 52x and swirling in the direction along the inner circumference of the first dust collection container 52 to the other side in the axial direction (first dust collection container 52 (bottom side). The first guide portion 74 extends so as to approach the dust collecting portion inlet 52x from one side in the axial direction toward the other side (in the illustrated example, from the upper side to the lower side). The end of the first guide section 74 may reach the dust collecting section inlet 52x. In other words, the first guide section 74 moves in the swirling direction of the airflow with respect to the dust collecting section inlet 52x as it goes from one side to the other side in the axial direction (from the upper side to the lower side in the illustrated example). It extends from the upstream position toward the dust collecting section inlet 52x. Note that, although the first guide portion 74 has been described as being provided in the structure 54, it may be provided in the inner circumferential surface of the first dust collecting container 52. In this case, the first guide portion 74 preferably comes into contact with the outer peripheral surface of the tapered portion 70 (structure 54).

The second guide portion 76 is a rib-shaped portion provided on the outer peripheral side of the tapered portion 70, similarly to the first guide portion 74. The second guide section 76 is a rib that functions as a guide member for guiding the airflow flowing into the dust collection space 56 from the dust collection section inlet 52x. The second guide portion 76 is formed between the first dust collecting container 52 and the first inner cylinder 60 so as to intersect with the axial direction and extend along the turning direction. The second guide portion 76 is connected to the terminal end of the first guide portion 74 described above.

The third guide portion 78 is a rib-shaped member provided on the inner peripheral side of the first inner cylinder 60 . The third guide portion 78 is arranged inside the internal space 84 of the first inner cylinder 60 . A plurality of third guide parts 78 are provided in the internal space 84 at predetermined intervals in the circumferential direction. The third guide portion 78 is formed to extend from one circumferential side of the internal space 84 to the other side. In this embodiment, when the structure 54 is cut along a plane perpendicular to the axial direction and viewed from one side (upper side) in the axial direction, The distal end (free end) is located at a position apart in the clockwise direction (the same direction as the turning direction) with respect to the connecting part with the circumferential surface. In addition, when the connecting body 62 is provided, the third guide part 78 is arranged in the internal space 84 formed between the tapered part 70 (first inner cylinder 60) and the connecting body 62.

The connecting body 62 functions as an airflow outflow section 67 for causing the air that has flowed into the dust collection space 56 to flow out of the first dust collection section 50, and although it is not an essential configuration, the airflow outflow section 67 may have a filter. Further, the connecting body 62 may be detachably connected to the first inner cylinder 60, and in this case, the other end of the connecting body 62 in the axial direction is connected inside the first inner cylinder 60. Ru. As shown in FIG. 9 and the like, the connecting body 62 is formed of, for example, a cylindrical frame. Hereinafter, as an example, the connecting body 62 will be described as the second inner cylinder 62A. The second inner cylinder 62A is disposed inside the first inner cylinder 60 (on the axis side of the first dust collecting section 50). The second inner cylinder 62A is connected to both or one of the first inner cylinder 60 and the one side cylinder part 64. In this embodiment, the second inner cylinder 62A is connected to the first inner cylinder 60. Thereby, an internal space 84 is formed between the first inner cylinder 60 and the second inner cylinder 62A. A plurality of the third guide portions 78 described above are provided inside the internal space 84 at predetermined intervals in the circumferential direction.

As shown in FIG. 14, the second inner cylinder 62A includes a second inner cylinder outer frame 90, a second inner cylinder inner frame 92, and a second inner cylinder filter 94 (filter).

The second inner cylinder outer frame 90 has a cylindrical shape and has a support portion 90a and an opening 90b in the middle portion in the cylinder axis direction. The strut portions 90a are columnar portions extending in the cylinder axis direction, and are provided in plurality (four in this embodiment) at predetermined intervals in the circumferential direction of the second inner cylinder outer frame 90. The opening 90b is a portion of the second inner cylinder outer frame 90 that is open between the support portions 90a, 90a arranged in the circumferential direction.

The second inner cylinder frame 92 is a cylindrical member arranged inside the second inner cylinder outer frame 90. The second inner cylinder frame 92 has a support portion 92a and an opening 92b in the middle portion in the cylinder axis direction. The strut portions 92a are columnar portions extending in the cylinder axis direction, and are provided in plurality (four in this embodiment) at predetermined intervals in the circumferential direction of the second inner cylinder inner frame 92. The opening 92b is a portion of the second inner cylinder frame 92 that is opened between the support portions 92a, 92a arranged in the circumferential direction.

The second inner cylinder filter 94 is for capturing dust contained in the air discharged from the internal space 84 via the second inner cylinder 62A. The second inner cylinder filter 94 has a mesh shape in which many fine holes are formed. The second inner cylinder filter 94 is curved along the second inner cylinder outer frame 90 and the second inner cylinder inner frame 92, and the second inner cylinder outer frame 90 and the second inner cylinder inner frame 92 are in a curved state. caught in between. As a result, the second inner cylinder filter 94 becomes a wall of the second inner cylinder 62A, and also passes through the opening 90b of the second inner cylinder outer frame 90 and the opening 92b of the second inner cylinder inner frame 92. It is said that it is possible to capture dust contained in the air. Note that in this embodiment, the second inner cylinder filter 94 is provided, but it may not be provided.

As shown in FIGS. 9 and 11, the one side cylinder part 64 is provided in a direction away from the bottom side of the first dust collection container 52 (one side in the axial direction) with respect to the second inner cylinder 62A described above. There is. The one side cylinder part 64 is provided integrally or detachably with the second inner cylinder 62A, and is provided at a position adjacent to the upper side of the second inner cylinder 62A. As shown in FIG. 11, the one side cylindrical portion 64 has an enlarged diameter portion 64a, an intermediate portion 64b, and a filter placement portion 64c.

The enlarged diameter portion 64a is a portion that continues upward from the second inner cylinder 62A side. The enlarged diameter portion 64a is formed so as to expand in a tapered shape toward the upper side. Further, the intermediate portion 64b is a portion provided at a position adjacent to the enlarged diameter portion 64a on the upper side in the axial direction. The intermediate portion 64b is formed to extend in the axial direction of the first dust collection container 52. A circumferential groove 64d extending in the circumferential direction is provided on the outer circumferential surface of the one side cylindrical portion 64. The one side cylindrical part 64 seals the gap formed between it and the inner circumferential surface of the first dust collection container 52 with an airtight member (second airtight member 64e) such as an O-ring attached to the circumferential groove 64d. A second sealing part 65 can be formed to seal the second sealing part 65. The filter placement portion 64c has approximately the same inner diameter as the first dust collection container 52. Therefore, almost no gap is formed between the outer circumferential surface of the filter arrangement part 64c and the inner circumferential surface of the first dust collecting container 52.

Further, the filter placement portion 64c has a step portion 64f formed at a portion forming a boundary with the intermediate portion 64b on the inner circumferential side. This stepped portion 64f is provided with an annular groove portion in which an airtight member 64j is disposed, and comes into contact with the lower end portion of the second filter 64h, thereby improving airtightness. A first filter 64g and a second filter 64h are arranged inside the filter arrangement part 64c. The first filter 64g is a filter made of, for example, nonwoven fabric or sponge. The first filter 64g is arranged on the step portion 64f. Further, the second filter 64h includes at least a pleated filter and a frame 64i surrounding the filter. The airtight member 64j comes into contact with the lower end of the frame 64i. Further, a pleated filter constituting the second filter 64h is disposed on the first filter 64g, and a frame body 64i is provided inside so as to surround the first filter 64g. Further, in the second filter 64h, an airtight member 64k is disposed on the upper surface of the frame 64i, and the airtight member 64k comes into contact with the intake side component 42a, thereby improving airtightness. Note that by separating the pleated filter of the second filter 64h and the first filter 64g, air is dispersed in the space, so that the surface of the pleated filter can be effectively utilized. This makes it possible to solve the problem that the filter becomes clogged early and the suction force decreases.

≪About the dust collection device 100≫
As shown in FIG. 15 and the like, the dust collection device 100 is disposed on the back side of a support 202 that constitutes a stand 200. The dust collection device 100 is configured to collect dust from the vacuum cleaner 1 by communicating with the first dust collecting section 50 of the vacuum cleaner 1 . The dust collection device 100 includes a device main body including a second dust collecting section 110 and a second electric blower 120, and a receiving section 130. Preferably, when the vacuum cleaner 1 is connected to the dust collection device 100, the main body of the dust collection device 100 is located directly below at least one of the first electric blower 14 and the battery 15a. Thereby, the space on the back side of the support column 202 and below the vacuum cleaner 1 can be utilized. Further, the dust collection device 100 has a configuration in which the receiving portion 130 is provided with a space portion 132 and a supporting portion 134, and the receiving portion 130 and the second dust collecting portion 110 are connected so as to communicate through a communicating portion 136. has been done. Further, the dust collection device 100 includes an opening means 150 for opening the first dust collecting section 50 of the vacuum cleaner 1 by arranging the first dust collecting section 50 of the vacuum cleaner 1 in the receiving section 130. As a result, the dust collecting device 100 opens the first dust collecting section 50 and applies the suction force generated by the operation of the second electric blower 120, thereby allowing the dust collecting section 50 to pass through the communication section 136 from the first dust collecting section 50 to the second electric blower 120. The second dust collecting section 110 is capable of collecting dust. The configuration of each part will be explained in more detail below.

The second dust collecting section 110 is a part where the dust sucked from the first dust collecting section 50 of the vacuum cleaner 1 is collected. The second dust collection section 110 can be configured to collect dust as it is or to be a cyclone type dust collection section like the first dust collection section 50, but in this embodiment, a paper pack is attached. This allows dust to collect inside the paper pack (so-called "paper pack type"). As shown in FIGS. 15 and 16, the second dust collection section 110 includes a second dust collection container 112 and a connection section 114.

The second dust collection container 112 is a hollow container having a second dust collection chamber 112a inside. Further, inside the second dust collecting container 112, there is provided a paper pack fixing part 112b for sandwiching and fixing a mount provided at the connection part of a paper pack for collecting dust (not shown). Further, on the surface constituting the second dust collection container 112 (the circumferential surface in this embodiment), a position corresponding to the opening provided in the mount of the paper pack when the paper pack is attached to the paper pack fixing part 112b is located. A communication hole 112c is provided in the. Further, the second dust collection container 112 can be opened and closed by attaching and detaching the lid 112d. Therefore, by removing the lid 112d, placing the paper pack inside the second dust collection chamber 112a, and fixing the mount of the paper pack to the paper pack fixing part 112b, the opening of the paper pack and the communication hole 112c are communicated with each other. be able to. Further, among the surfaces (bottom surface in this embodiment) constituting the second dust collection container 112, the surface separating it from the second electric motor housing chamber 140 (blower arrangement space) in which the second electric blower 120 is accommodated is , a ventilation hole 112e is provided.

The connecting portion 114 has a socket 114a and a connecting path 114b. The socket 114a is a part to which a pipe part 136b forming a communication part 136 connecting the receiving part 130 and the second dust collecting part 110 is connected. The connection path 114b is a path that connects the socket 114a and the communication hole 112c provided in the second dust collection container 112 so that air and dust can pass therethrough.

The second electric blower 120 is capable of generating suction force as it operates. The second electric blower 120 is arranged in a second electric motor storage chamber 140 that communicates with the second dust collection container 112 of the second dust collection section 110 via the ventilation hole 112e. As long as the second electric blower 120 can exert a suction force on the second dust collecting container 112, its arrangement, installation posture, etc. can be set as appropriate. In the present embodiment, as the second electric blower 120 operates, vibrations tend to occur in the radial direction of the motor included in the second electric blower 120, and the second electric blower 140 is located in the dust collection device 100. The motor of the second electric blower 120 is designed to suppress the generation of vibration noise at the part of the dust collection device 100 that makes contact with the floor where the device body is placed. The rotation axis is arranged so as to face in the vertical direction.

As shown in FIGS. 1 to 3, etc., the receiving section 130 receives the first dust collection section 50 of the vacuum cleaner 1. Specifically, the receiving part 130 has a first dust collecting part recess 130a formed so that the lower end side part of the first dust collecting part 50 fits therein. In addition, as shown in FIG. 7, the receiving part 130 has an extension pipe recess 130b formed so as to fit or abut on a part of the circumference of the cylindrical part having the suction port 38y in the main body part 10. have Preferably, the cylindrical portion of the main body portion 10 has a step shape, and the step surface 10a may be supported by the receiving portion 130 from below. Note that the extension tube 180 may fit into or abut a part of the circumference of the extension tube recess 130b. Further, the receiving portion 130 is provided with an opening means 150.

The opening means 150 is for opening the first dust collection chamber 52a of the first dust collection section 50. The opening means 150 can be structurally (mechanically) opened by rotating the opening/closing part 52c provided in the first dust collection part 50. Specifically, as shown in FIG. 18, when the first dust collecting part 50 is fitted into the first dust collecting part recess 130a, at the position where the abutted part 52f of the opening/closing part 52c comes, A protruding contact portion 152 is provided to function as an opening means 150. When the first dust collecting part 50 is fitted into the first dust collecting part recess 130a, the contact part 152 comes into contact with the abutted part 52f on the first dust collecting part 50 side. By fitting the first dust collecting part 50 into the first dust collecting part recess 130a, a pressing force is applied from the contact part 152 to the abutted part 52f in a direction opposite to the urging force of the urging member 52h. Then, the opening/closing portion 52c rotates around the rotation shaft 52e and enters the open state. On the other hand, when the first dust collecting part 50 is removed from the first dust collecting part recess 130a and the fitting between them is released, the pressing force acting from the abutting part 152 to the abutted part 52f is canceled. Accordingly, the opening/closing portion 52c returns to the closed state due to the urging force of the urging member 52h. In addition, when the opening/closing part 52c returns to the closed state, the opening/closing part 52c may be configured to engage with the first dust collection container 52. Note that, as described above, the receiving portion 130 may be provided with the abutting portion 152A instead of or in addition to the abutting portion 152.

Moreover, the space part 132 provided in the receiving part 130 is a space that can receive the opening/closing part 52c that becomes open by fitting the first dust collecting part 50 into the first dust collecting part recess 130a. It is formed at a position in the opening direction of the opening/closing part 52c (in the present embodiment, on the lower side) with respect to the dust collecting part recess 130a. Therefore, the opening/closing part 52c can smoothly perform opening/closing operations without interfering with the receiving part 130.

Further, the receiving part 130 is provided with a support part 134, and the support part 134 supports the opening/closing part 52c which becomes open when the first dust collecting part 50 is fitted into the first dust collecting part recess 130a. It is considered possible. In this embodiment, when the opening/closing part 52c is in the open state, the opening/closing part 52c is in an inclined state. Therefore, the support part 134 is formed in an inclined state so as to follow the opening/closing part 52c in the open state.

The receiving part 130 communicates with the first dust collecting part 50 toward the second dust collecting part 110 via the communicating part 136 so as to be able to suck dust. The communication portion 136 has a communication port 136a that communicates with the first dust collecting portion recess 130a, and a pipe portion 136b that is connected to the communication port 136a. The pipe portion 136b is configured by a hose, a pipe, or the like (in this embodiment, a pipe). The communication part 136 communicates with the first dust collection part 50 which is in the open state by fitting into the first dust collection part recess 130a of the receiving part 130. In the communication section 136, the distance between the opening/closing section 52c in the open state and the inner wall of the communication section 136 becomes narrower toward the downstream side in the dust suction direction from the first dust collection section 50 to the second dust collection section 110. It is formed like this. Further, a portion of the pipe portion 136b opposite to the connection side with the communication port 136a is connected to a socket 114a provided in the connection portion 114 of the second dust collecting portion 110. Thereby, the receiving part 130 is supported by the pipe part 136b on the upper side with respect to the second dust collecting part 110. Therefore, by fitting the first dust collecting part 50 into the first dust collecting part recess 130a of the receiving part 130, the vacuum cleaner 1 is supported by the pipe part 136b via the receiving part 130. Further, the tube portion 136b is aligned with the extension tube 180 fitted into the extension tube recess 130b of the receiving portion 130. Therefore, by placing the suction tool 190 connected to the distal end side of the extension pipe 180 on the stand 200 and fitting the first dust collecting section 50 into the receiving section 130, the vacuum cleaner 1 can be installed side by side. The state is such that it is stably supported by the disposed extension tube 180 and the tube portion 136b.

≪About controlling the vacuum cleaner system S≫
The vacuum cleaner system S can be configured such that the dust collection device 100 starts operating when the vacuum cleaner 1 is connected to the dust collection device 100. The vacuum cleaner 1 may be connected to the dust collection device 100, and the vacuum cleaner 1 may be turned on by contacting a switch provided on the stand 200, so that the dust collection device 100 starts the suction operation. . As another form, the stand 200 may have a charging mechanism, and the dust collection device 100 may start the suction operation when it detects that the stand 200 and the vacuum cleaner 1 are energized. In this case, apart from the wiring for charging, a configuration may be adopted in which wiring is provided between the energizing terminal of the stand 200 and the control unit 17 for detecting energization.

≪Modification example≫
Although the vacuum cleaner system S of this embodiment has the configuration as described above, it can be different from that described above without departing from the spirit of the present invention. For example, in the present embodiment, a configuration has been exemplified in which the first dust collecting section 50 is fitted into the receiving section 130 so that the abutting section 152 naturally comes into contact with the abutted section 52f. The invention is not limited to this.

Specifically, it is possible to provide an operating section for operating one or both of the abutted section 52f and the abutting section 152, so that the two come into contact with each other by operating the operating section. . In this case, the operating section is preferably provided in either the vacuum cleaner 1 or the dust collection device 100 together with a member that is operated by operating the operating section. More specifically, it is preferable that the abutting part 152 is movable and can be brought into contact with the abutted part 52f by operating the operating part. Thereby, the user of the vacuum cleaner system S can open the closing part 52g or transfer dust from the first dust collecting part 50 to the second dust collecting part 110 at desired timing.

Moreover, when the contact part 152 is made movable, the contact part 152 (opening means 150) may be provided on the first dust collecting part 50 side. For example, it is preferable that the abutting part 152 is shaped like a shaft, and that the abutting part 152 can push the obstructing part 52g from inside the first dust collection container 52 to open the obstructing part 52g. . In this case, the position at which the abutting portion 152 abuts in the closing portion 52g is the abutted portion 52f2 (not shown). Preferably, the abutting portion 152 is configured to push a portion of the closing portion 52g away from the rotation axis 52e from the axial center position of the first dust collection container 52 as the abutted portion 52f2. When there is a locking structure in which the closing portion 52g locks with the first dust collection container 52 in the closed state, it is preferable that the contact portion 152 pushes the locking structure side more than the rotation shaft 52e. Note that the closing portion 52g may be provided with an opening, and a valve or a lid may be rotatably provided in the closing portion 52g so that the opening can be opened and closed. In this case, the above-mentioned opening operation of the valve or lid can be performed mechanically by the abutting part 152 and the abutted parts 52f, 52f2, regardless of whether they are movable or not.

Further, although the dust collection device 100 has a configuration in which the device main body and the receiving portion 130 are connected through the pipe portion 136b, the present invention is not limited to this. It is also possible to configure the device main body to have a receiving portion 130 and to extend the device main body together with the connecting path 114b to a height at which the first dust collecting portion 50 fits into the receiving portion 130 connected to the connecting path 114b. In this case, there is no need to separately provide the tube portion 136b.

Moreover, although the first dust collection part 50 was configured to open the bottom of the first dust collection container 52, it may also be configured to open the side surface to form a waste port. Even in this case, the receiving part 130 may receive the first dust collecting container 52 from the disposal port side on the side surface thereof, and the opening/closing part 52c can be opened diagonally or horizontally by rotation.

Although the vacuum cleaner 1 of the present embodiment has been described using an example in which the main body 10 and the suction tool 190 are connected to the dust collection device 100 with the extension tube 180 connected, the present invention is not limited to this. It's not something you can do. The vacuum cleaner 1 may be connected to the dust collection device 100 with the suction tool 190 attached to the suction port 38y of the main body 10.

The vacuum cleaner system S described above is configured by fitting the main body 10 of the vacuum cleaner 1 into the receiving part 130 of the dust collection device 100 and operating the second electric blower 120 with the opening/closing part 52c open. The structure is capable of sucking not only dust present in the dust collecting section 50 but also dust attached to the first filter 64g and the second filter 64h (or one filter when one of the first filter 64g and the second filter 64h is arranged). It is good to say. Specifically, regarding the structure 54 of the vacuum cleaner 1, the extending portion 72 extends toward the closing portion 52g (opening/closing portion 52c) forming the bottom of the first dust collecting portion 50, and is preferably closed. It comes into contact with the bottom of the opening/closing part 52c.

[About the vacuum cleaner according to the fourth aspect of the present invention]
Conventionally, as disclosed in Japanese Patent Application Laid-open No. 2004-283327, there has been provided a vacuum cleaner that generates a suction airflow and collects dust using the generated airflow. The vacuum cleaner disclosed in this patent document includes a vacuum cleaner body having a dust case on the main body side that collects and stores dust, and a dust case on the installation stand side that stores dust from the dust case on the main body side. and an installation stand, and includes a means for discharging the dust in the dust case on the side of the main body of the vacuum cleaner into the dust case on the side of the installation stand when the main body of the vacuum cleaner is installed on the installation stand. ing. In addition, the vacuum cleaner disclosed in the patent document is provided with a valve on each of the vacuum cleaner body and the installation stand, and by opening the valve by the airflow of the fan motor, the vacuum cleaner is moved from the dust case on the vacuum cleaner body side to the installation stand side. It is said that the dust can be discharged into the dust case.

However, since the vacuum cleaner of Patent Document 1 collects dust into a dust case on the installation stand side by circulating airflow, there is a problem that dust tends to remain in the dust case on the main body side.

Therefore, an object of the present invention is to realize a vacuum cleaner unit that can easily collect dust on the vacuum cleaner side.

(4-1) The vacuum cleaner system S provided to solve the above-mentioned problems includes a vacuum cleaner 1 and a dust collection device 100, and the vacuum cleaner 1 generates suction force. The main body part 10 has a first electric blower 14 that allows the dust to flow, and a first dust collection part 50 that collects dust, and the first dust collection part 50 has a dust collection part inlet 52x. A first dust collecting container 52 (outer cylinder), a structure 54 having a dust collecting space exhaust part 80 and configuring a dust collecting space 56 between the first dust collecting container 52 and the first dust collecting container 52 The structure 54 has a tapered part 70 whose outer shape becomes smaller as it goes from one side to the other side in the central axis direction. The dust collecting device 100 collects dust from the first dust collecting section 50 of the vacuum cleaner 1, and includes a second dust collecting section 110 where dust is collected and a second electric motor that generates suction force. The vacuum cleaner 1 or the dust collection device 100 is provided with an opening means 150 for opening the opening/closing part 52c.

In the vacuum cleaner system S, an opening 16d provided at the bottom of the first dust collection container 52 constituting the first dust collection section 50 of the vacuum cleaner 1 can be opened and closed by an opening/closing part 52c. Further, the vacuum cleaner system S includes a dust collection device 100 for collecting dust from the first dust collection section 50 of the vacuum cleaner 1, and generates a suction force with a second electric blower 120 to collect dust. Dust can be collected in the second dust collecting section 110. Further, in the vacuum cleaner system S, the vacuum cleaner 1 or the dust collection device 100 is provided with an opening means 150 for opening the opening/closing part 52c. Therefore, by opening the opening/closing part 52c provided at the bottom of the first dust collecting container 52 using the opening means 150, the vacuum cleaner system S removes the dust collected in the first dust collecting part 50 due to the influence of gravity. It can be dropped. In addition, by operating the second electric blower 120 provided in the dust collection device 100 while the opening/closing portion 52c is open, a suction force toward the second dust collection portion 110 is applied to the dust. It can be made to work. Therefore, the vacuum cleaner system S applies both gravity and the suction force of the second electric blower 120 to the dust collected in the first dust collection part 50, and collects the dust in the second dust collection part 110. be able to. Therefore, in the vacuum cleaner system S, the dust collected on the vacuum cleaner 1 side can be easily and smoothly collected by the dust collection device 100.

(4-2) A vacuum cleaner system S is the vacuum cleaner system S of (4-1) above, in which the structure 54 includes a first inner cylinder 60 (inner cylinder) having a tapered portion 70 and a first inner cylinder. It is preferable that it has an extending portion 72 extending from the tube 60 to the other side in the central axis direction.

Since the vacuum cleaner system S has such a configuration, when the vacuum cleaner system S rotates in the dust collection space 56 and an airflow that rises toward the tapered portion 70 is generated at a position on the axis side of the dust collection space 56, the airflow and this The extension portion 72 obstructs the flow of dust contained in the dust. That is, in the case of the above-mentioned configuration, the airflow and dust that have flown up from the bottom of the first dust collection container 52 at a position on the axis side of the dust collection space 56 are difficult to spread in a direction intersecting the axial direction. Thereby, the vacuum cleaner system S can make it difficult for dust such as hair and dust contained in the airflow to become entangled with the tapered portion 70 in the dust collection space 56.

In addition, in the said embodiment, although the example which made the extension part 72 into a cylindrical shape was shown, this invention is not limited to this. The vacuum cleaner 1 can also be provided with something like a brush or comb teeth extending from the first inner cylinder 60 to the other side in the axial direction, and this can be provided as an extension part 72. .

(4-3) The vacuum cleaner system S is the vacuum cleaner system S of (4-2) above, in which the other end of the extension portion 72 in the central axis direction is spaced apart from the opening/closing portion 52c. It would be good if it was characterized by this.

With this configuration, the vacuum cleaner system S can prevent the airflow rising from the bottom of the first dust collection container 52 from spreading outward while ensuring a sufficient internal volume of the dust collection space 56. That is, by having the vacuum cleaner system S configured as described above, dust tends to collect below the first inner cylinder 60 and inside the extension part 72.

(4-4) In the vacuum cleaner system S, the first inner cylinder 60 has a closed end on the other side in the central axis direction in the vacuum cleaner system S of (4-2) to (4-3) above. It is good if it is characterized by the fact that

By having the above-described configuration, the vacuum cleaner system S can avoid clogging of the other axial end of the first inner cylinder 60 with dust.

Although the present embodiment shows an example in which the other end of the first inner cylinder 60 in the axial direction is closed, the present invention is not limited to this, and the other end of the first inner cylinder 60 in the axial direction is closed. It is also possible to leave the end portions unoccluded. Note that when the other end of the first inner cylinder 60 in the axial direction is not closed, it is preferable to adopt a structure in which this part is not easily clogged with dust.

(4-5) The vacuum cleaner system S is the vacuum cleaner system S of (4-1) to (4-4) above, in which the structure 54 or the first dust collection container 52 is on one side in the central axis direction. It is preferable to have a first guide part 74 that extends from the upstream side in the turning direction toward the dust collecting part inlet 52x as it goes to the other side.

Since the vacuum cleaner system S includes the first guide section 74 as described above, the airflow flowing into the dust collection space 56 from the dust collection section inlet 52x is guided by the first guide section 74 and directed in the axial direction. It is smoothly guided toward the other side (the bottom of the first dust collection container 52). That is, in the vacuum cleaner 1 of the present embodiment, the swirling airflow that flows into the dust collection space 56 from the dust collection section inlet 52x and is generated on one side (upper side) in the axial direction tends to flow toward the other side in the axial direction. By doing so, it is possible to suppress dust such as hair and dust contained in the airflow from wrapping around the tapered portion 70 of the first inner cylinder 60.

Although the present embodiment shows an example in which the first guide part 74 as described above is provided, the present invention is not limited to this. A configuration may be adopted in which another guide member is provided in place of the guide portion 74. When the first guide portion 74 is not provided, for example, the dust collecting portion inlet 52 It is a good idea to take measures such as optimizing the shape, etc. Moreover, when providing another guide member in place of the first guide part 74, similarly to the first guide part 74, the airflow flowing into the dust collection space 56 from the dust collection part inlet 52x is directed toward the other side in the axial direction. The direction of the airflow may be guided so that it flows smoothly, or the direction of the airflow may be changed to the other side in the axial direction before the airflow flowing in from the dust collection section inlet 52x goes around once in the circumferential direction of the dust collection space 56. It is a good idea to do something like that.

(4-6) The vacuum cleaner system S is the vacuum cleaner system S of (4-1) to (4-4) above, in which the structure 54 or the first dust collection container 52 is the dust collection part inlet 52x. It has a second guide part 76 that guides the airflow flowing into the dust collection space 56 from the (inflow port), and the second guide part 76 is provided so as to extend in a direction intersecting the axial direction. It is good if it is something that does.

Since the vacuum cleaner 1 of the present embodiment includes the second guide portion 76 as described above, the airflow can be smoothly introduced into the dust collection space 56 from the dust collection portion inlet 52x and rotated.

In addition, in this embodiment, although the structure which provided the second guide part 76 mentioned above was illustrated, this invention is not limited to this, The structure which does not provide the second guide part 76, or the second guide part 76 In place of the section 76, a structure that exhibits an equivalent function may be provided.

(4-7) The vacuum cleaner system S is the vacuum cleaner system S of (4-1) to (4-6) above, in which the first dust collection section 50 is located closer to the center axis than the dust collection section inlet 52x. It is preferable that it has a contact portion that comes into contact with the structure 54 on one side in the direction. The contact portion may be, for example, a brush, a blade, or a combination thereof.

Since the vacuum cleaner system S has such a configuration, when the structure 54 is removed from the first dust collecting section 50, dust entangled with the structure 54 can be removed by the contact portion.

(4-8) In the vacuum cleaner system S of (4-1) to (4-7) above, the vacuum cleaner system S has an opening means 150 on one side of the dust collection device 100 and the vacuum cleaner 1. Abutting portions (contacting portions 152, 152A) are provided, and abutted portions (contacted portions 52f, 52f1) are provided on the other side, and the opening/closing portion 52c is such that the abutting portion is abutted. It is preferable that the opening is opened by coming into contact with the contact portion.

Since the vacuum cleaner system S has such a configuration, the vacuum cleaner 1 can be opened and closed by the opening means 150 by arranging the vacuum cleaner 1 with respect to the dust collection device 100 so that the abutting part and the abutted part are in contact with each other. The portion 52c can be in an open state.

(4-9) In the vacuum cleaner system S of (4-8) above, the vacuum cleaner system S has a contact portion (abutment It is preferable that the portions 152, 152A) come into contact with the abutted portions (the abutted portions 52f, 52f1).

Since the vacuum cleaner system S has such a configuration, by connecting the vacuum cleaner 1 to the dust collection device 100, the abutting portion 152 naturally comes into contact with the abutted portion 52f, and the opening/closing portion 52c is opened. It can be in an open state. Thereby, the vacuum cleaner system S does not require a separate operation to open the opening/closing part 52c, and is excellent in terms of convenience.
