When a configuration is adopted in which the dust collection box is provided in the main body together with the rotating brush and the electric motor, and no electric blower is provided, as in the vacuum cleaner disclosed in Patent Document 1, no sound is generated by driving the electric blower, and therefore it is possible to suppress noise during cleaning. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Publication No. 53-134769 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a vacuum cleaner is configured without an electric blower that generates suction power, as in the vacuum cleaner of Patent Document 1, there is a problem that it is difficult to draw in dust adhering to a rug or carpet, for example, into the main body.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a vacuum cleaner that can selectively use either cleaning that utilizes the suction force of an electric blower or cleaning that utilizes the rotation of a rotating brush. [Means for solving the problem]

[0006] An embodiment of the present invention provides an electric vacuum cleaner that solves the above-mentioned problems, and comprises an electric blower that generates suction force, a dust collecting section that collects dust, an inlet for sucking in dust, and a rotating cleaning body that rotates by driving a drive section, wherein the dust collecting section has a first dust collecting section and a second dust collecting section that is arranged on the suction port side of the first dust collecting section in a path connecting the first dust collecting section and the suction port, and is characterized in that it is switchable between one of a plurality of operating modes including a first mode in which the drive section is driven with the electric blower stopped, and a second mode in which the electric blower is driven.

[0007] The vacuum cleaner of the present invention can be used in a first mode to rotate the rotary cleaning body for cleaning without generating the driving noise of the electric blower by driving the driving unit while the driving of the electric blower is stopped. Also, the vacuum cleaner of the present invention has a dust collecting unit that includes, in addition to the first dust collecting unit, a second dust collecting unit that is disposed on the suction port side of the first dust collecting unit. Therefore, when the vacuum cleaner of the present invention is operated in the first mode in which the suction force is not generated by the electric blower, dust collected by the rotation of the rotary cleaning body can be collected in the second dust collecting unit.

[0008] On the other hand, the vacuum cleaner of the present invention can also perform cleaning using the suction force of the electric blower by driving the electric blower in the second mode. Also, the vacuum cleaner of the present invention has a second dust collecting section on the suction port side of the first dust collecting section. Therefore, the vacuum cleaner of the present invention can collect dust that has been collected in the second dust collecting section by operation in the first mode in the first dust collecting section by the suction force of the electric blower in the second mode.

[0009] As described above, the vacuum cleaner of the present invention has a dust collecting section that includes a first dust collecting section and a second dust collecting section, and is operable in a plurality of modes including a first mode and a second mode, thereby enabling the vacuum cleaner of the present invention to selectively use cleaning that utilizes the suction force of the electric blower and cleaning that utilizes the rotation of the rotating brush. Effect of the Invention

[0010] According to the present invention, it is possible to realize a vacuum cleaner that can selectively use cleaning that utilizes the suction force of an electric blower and cleaning that utilizes the rotation of a rotating brush. [Brief description of the drawings]

[0012] Hereinafter, a vacuum cleaner 10 according to one embodiment of the present invention will be described in detail with reference to the accompanying drawings. Note that the accompanying drawings are schematic diagrams of the various parts of the vacuum cleaner 10, and are not necessarily drawn to scale. In addition, in the drawings, similar components are denoted by similar reference numerals. Furthermore, in this specification, terms indicating positional relationships such as up, down, left, right, front, back, etc. will be described based on the state in which the vacuum cleaner 10 is set upright as shown in FIG. 1, unless otherwise specified. In the following description, the configuration of the vacuum cleaner 10 will be described first, followed by the operation of the vacuum cleaner 10.

[0013] <Configuration of the vacuum cleaner 10> As shown in FIG. 1, the vacuum cleaner 10 is an example of a vacuum cleaner having a stick-shaped (vertical) appearance. The vacuum cleaner 10 can be, for example, one that obtains power from an external power source via a power cord, but in this embodiment, it is a rechargeable vacuum cleaner. As shown in FIG. 1, the vacuum cleaner 10 includes a vacuum cleaner body 20, a suction tool 40, and an extension tube 90. The vacuum cleaner 10 constitutes a vacuum cleaner system S in combination with a separately provided support device 300. The vacuum cleaner 10 can be installed in a state in which it is supported by the support device 300. Note that "installation" is not limited to an action in which the user supports the vacuum cleaner 10 on the support device 10 when the vacuum cleaner 10 is a stick type or canister type, but may also include an action in which the vacuum cleaner 10 travels on its own and connects to the support device 300 when the vacuum cleaner 10 is a robot vacuum cleaner. The configuration of each part will be described in more detail below.

[0014] <About the vacuum cleaner body 20> The vacuum cleaner main body 20 constitutes the main body of the vacuum cleaner 10 and is a part that exerts a suction force to collect dust. Specifically, the vacuum cleaner main body 20 includes a housing (main body) 20a having an electric blower 22 for generating suction force, and a first dust collecting part 24 for collecting dust contained in the sucked air.

[0015] The first dust collecting section 24 captures and collects dust that arrives from the suction tool 40 side. The first dust collecting section 24 may be provided as a part of the main body section 20a, or may be provided separately from the main body section 20a so as to be detachable. The first dust collecting section 24 may be, for example, a so-called paper bag type or a so-called cyclone type. In this embodiment, the first dust collecting section 24 is of a cyclone type. In addition to the electric blower 22 and the first dust collecting section 24, the vacuum cleaner main body 20 includes, in the main body section 20a, for example, a drive circuit that drives the electric blower 22 and other electronic components, a control device 32 that controls the operation of the vacuum cleaner 10, a battery 34 for supplying power, and other components.

[0016] The vacuum cleaner body 20 is also provided with a grip part 26 and an operation part 28 on the handle. The grip part 26 is a part provided to enable a user of the vacuum cleaner 10 to grip the vacuum cleaner body 20. That is, the vacuum cleaner 10 can be held by, for example, gripping the grip part 26. The operation part 28 is provided for operating the vacuum cleaner 10. For example, by providing the operation part 28 on the grip part 26 as shown in FIG. 1, the user can operate the operation part 28 while gripping the grip part 26.

[0017] Moreover, the vacuum cleaner body 20 has a pipe connection part 22b on the main body part 20a. The pipe connection part 22b is a part to which a hollow extension pipe 90 that connects the vacuum cleaner body 20 and the suction tool 40 is connected. The pipe connection part 22b also communicates with the first dust collecting part 24. Therefore, by connecting the joint part 44 of the suction tool 40 to the pipe connection part 22b via the extension pipe 90, a path that connects the suction tool 40 side and the first dust collecting part 24 is formed.

[0018] <About Suction Tool 40> The suction tool 40 is for sucking in air and dust from the outside. As shown in Fig. 2, the suction tool 40 has a suction tool main body 42 (main body) and a joint part 44. As shown in Fig. 3, the suction tool 40 has a rotating cleaning body 46, a cleaning body drive part 48 (drive part), and a second dust collecting part 50 inside the suction tool main body 42. In addition to these, the suction tool 40 also has an electric current part 52 and the like.

[0019] The suction tool body 42 is a part that is placed on the floor during cleaning, and has a shape that is long in the left-right direction compared to the front-rear direction in which the user moves during cleaning. As shown in Figures 3 to 5, the suction tool body 42 has a rotating cleaning body mounting section 60, a suction port 62, a second dust collecting section mounting section 64, and a storage section 66.

[0020] The rotary cleaning body mounting portion 60 is a portion in which the rotary cleaning body 46 is mounted. The rotary cleaning body mounting portion 60 extends in the left-right direction of the suction tool main body 42, and has a hollow space capable of housing the rotary cleaning body 46.

[0021] The suction port 62 is an opening for sucking in dust on the bottom side of the suction tool main body 42. In this embodiment, a rotating cleaning body arrangement portion 60 is provided in the suction space in which the suction port 62 is formed.

[0022] 3 to 5, second dust collecting section accommodating section 64 is a portion where second dust collecting section 50, which will be described later in detail, is arranged. Second dust collecting section accommodating section 64 is configured so that second dust collecting section 50 can be arranged at a position closer to suction port 62 than first dust collecting section 24 in a dust passage path connecting first dust collecting section 24 and suction port 62.

[0023] As can be seen from FIG. 4, FIG. 6, and FIG. 7, the second dust collecting unit arrangement part 64 includes an opening 64a, a cover part 64b, a biasing member 64c, and a lock part 64d. The opening 64a is an opening provided so that the second dust collecting unit 50 can be inserted and removed from the top surface of the suction tool main body part 42 and attached / detached. The opening 64a is a rectangular opening formed so as to extend in the longitudinal direction (left-right direction) of the suction tool main body part 42 along the rotating cleaning body arrangement part 60 (rotating cleaning body 46). The cover part 64b is a lid-like part that opens and closes the opening 64a. The cover part 64b is supported rotatably by a hinge or the like on one side of the short side direction (front-rear direction) of the opening 64a. The biasing member 64c biases the cover part 64b in the direction to open the opening 64a. In this embodiment, the biasing member 64c is formed of a torsion spring and is disposed on the pivot side of the cover portion 64b. The locking portion 64d is for closing the cover portion 64b so that the cover portion 64b does not open. In this embodiment, the locking portion 64d is provided so as to be exposed on the top surface side of the suction tool main body 42 on the side opposite to the side on which the biasing member 64c is provided (the free end side of the cover portion 64b).

[0024] Since the second dust collecting unit arrangement section 64 is configured as described above, the free end side of the cover section 64b is biased to jump up by the biasing force of the biasing member 64c by releasing the locking portion 64d. As a result, as shown in Figures 6 and 7, the second dust collecting unit arrangement section 64 is in a state in which the opening 64a is open and the second dust collecting unit 50, which will be described in detail later, can be inserted and removed. In addition, in a state in which the free end side of the cover section 64b is pressed against the biasing force of the biasing member 64c toward the top surface side of the suction tool main body 42 and the opening 64a is blocked by the cover section 64b, the locking portion 64d prevents the cover section 64b from jumping up, thereby closing the opening 64a as shown in Figure 2.

[0025] 3, the accommodation section 66 is for accommodating the driving machine 210 constituting the cleaning body driving section 48 described in detail below, wiring for supplying power to the driving machine 210, and the like. The accommodation section 66 is capable of arranging the driving machine 210 and wiring at a position away from the dust passage path. In this embodiment, the accommodation section 66 is provided at a position on the opposite side of the second dust collecting section 50 from the rotating cleaning body 46 (rearward of the second dust collecting section 50).

[0026] The joint part 44 is provided at a position on the suction tool main body 42 that is on the rear side of the vacuum cleaner 10 (a position on the opposite side of the rotary cleaning body 46 with respect to the second dust collecting part 50) so as to communicate with the second dust collecting part 50 via the communication part 45. The joint part 44 is attached to the suction tool main body 42 so as to be rotatable within a predetermined rotation range (at least one of the front-rear direction and the left-right direction). The joint part 44 is a part to which the extension tube 90 is connected, similar to the tube connection part 22b of the vacuum cleaner main body 20 described above. The joint part 44 is cylindrical, and communicates with the second dust collecting part 50 at the base end.

[0027] 3 and other figures, the rotating cleaning body 46 is a cylindrical member that is housed in and rotatably supported in the rotating cleaning body mounting portion 60 of the suction tool main body 42. The rotating cleaning body 46 receives power from a cleaning body drive portion 48, which will be described in detail later, and is rotatable in the rotating cleaning body mounting portion 60. The rotating cleaning body 46 has a cleaning body main body 200 that extends in the longitudinal direction (left-right direction) of the suction tool main body 42, and an attachment portion 202.

[0028] The attachment parts 202 are parts used for attaching the rotating cleaning body 46 to the suction tool main body 42. The attachment parts 202 are attached to the cleaning body 200 as separate members on one side and the other side in the longitudinal direction of the cleaning body 200, but may be integral with the cleaning body 200. The rotating cleaning body 46 is supported rotatably relative to the suction tool main body 42 by attaching the attachment parts 202, 202 provided on both ends (hereinafter, the two may be distinguished as "attachment part 202a" and "attachment part 202b" as necessary) to predetermined attachment positions provided within the suction tool main body 42.

[0029] 10(a), the mounting portion 202a has an end portion 205 having a prismatic columnar shape (having a substantially square cross-sectional shape) at one axial end side of the rotating cleaning body 46, and a flange portion 207a provided at a position adjacent to the end portion 205 in the axial direction. The end portion 205 is rotatably attached to the cleaning body 200 (flange portion 207a).

[0030] Here, as shown in Fig. 8 and Fig. 9, the receiving portion 42c of the suction tool main body 42 to which the mounting portion 202a of the rotary cleaning body 46 is attached is separable into a lower receiving portion 42x and an upper receiving portion 42y. The lower receiving portion 42x is removable from the back surface side of the suction tool main body 42. Specifically, as shown in Fig. 9, the portion where the upper receiving portion 42y is formed is provided with an upper engaging portion 42p on the front side (upper side in the illustrated state) of the suction tool main body 42 and a concave upper engaged portion 42q on the back surface side (lower side in the illustrated state). In addition, the lower receiving portion 42x is provided with a lower engaged portion 42r that can engage with the upper engaging portion 42p at a position corresponding to the upper engaging portion 42p on the upper receiving portion 42y side, and a convex lower engaging portion 42s is provided at a position corresponding to the upper engaged portion 42q. The lower receiving part 42x is provided with a claw part 42t, which allows the lower engaging part 42s to be swung. With this configuration, the lower engaged part 42r is engaged with the upper engaging part 42p, and then the lower engaging part 42s is inserted into and engaged with the upper engaged part 42q, so that the lower receiving part 42x can be attached to the upper receiving part 42y. Conversely, when removing the lower receiving part 42x from the upper receiving part 42y, the claw part 42t is operated to first release the engagement between the lower engaging part 42s and the upper engaged part 42q. Thereafter, the lower engaged part 42r is removed from the upper engaging part 42p, so that the lower receiving part 42x can be removed from the upper receiving part 42y. The upper receiving part 42y is provided on the inside of the suction tool main body 42. By attaching the lower receiving portion 42x to the back surface side of the suction tool body 42, the receiving portion 42c can be formed.

[0031] As shown in Fig. 8, upper receiving portion 42y has upper end fitting portion 42h, upper flange fitting portion 42i, and upper shaft support portion 42j. Upper end fitting portion 42h is a portion that opens toward the bottom surface side of suction tool main body 42 so that end portion 205 having a rectangular column shape as described above can be fitted therein. Upper flange fitting portion 42i is a portion that opens toward the bottom surface side of suction tool main body 42 so that flange portion 207a can be fitted therein. Upper shaft support portion 42j is a portion that curves in an arc shape along the axis that constitutes mounting portion 202a.

[0032] 8 and 9, the lower receiving portion 42x has a lower end abutment portion 42k and a lower shaft support portion 42l at positions corresponding to the above-mentioned upper end fitting portion 42h and upper shaft support portion 42j, respectively. The lower end abutment portion 42k is a block-shaped portion formed so as to abut against the outer circumferential surface (one side) of the end portion 205 from the cleaning surface side, and the upper end fitting portion 42h abuts against the other outer circumferential surfaces (three sides) of the end portion 205, thereby fixing the end portion 205 to the suction tool main body 42. Similarly to the upper shaft support portion 42j, the lower shaft support portion 42l is curved so as to follow the axis forming the mounting portion 202a. The rotating cleaning body 46 can be incorporated into the suction tool main body 42 by fitting the end 205 and flange portion 207a into the upper end fitting portion 42h and the upper flange fitting portion 42i, respectively, and then attaching the lower receiving portion 42x to the upper receiving portion 42y.

[0033] On the other hand, as shown in Fig. 10, the attachment portion 202b supports the other axial end side (opposite to the attachment portion 202a) of the rotating cleaning body 46. The attachment portion 202b is provided with a first attachment body 202x that can be connected to a second attachment body 202y, which will be described later. The first attachment body 202x is fixed to an end of the cleaning body main body 200. The second attachment body 202y is provided on a driven side pulley 216, which will be described later, and is disposed on the suction tool main body 42 (lower case 42a) side. The first attachment body 202x and the second attachment body 202y are connectable and separable in the axial direction.

[0034] The first mounting body 202x includes a mounting recess 202e and a first flange portion 202i. The mounting recess 202e is formed in a concave shape on the end surface of the first mounting body 202x. The mounting recess 202e may have any shape, but in this embodiment, it is cross-shaped. The mounting recess 202e is a portion into which a mounting protrusion 202j of a second mounting body 202y described below can be fitted and engaged. The first flange portion 202i is provided at an end (the end on the second mounting body 202y side) of the first mounting body 202x so as to bulge outward in the radial direction.

[0035] As shown in FIG. 10 and FIG. 11, the second attachment body 202y has an attachment protrusion 202j and a shaft portion 202k. The attachment protrusion 202j protrudes in the axial direction at the end of the second attachment body 202y and is engageable with the above-mentioned attachment recess 202e. The attachment protrusion 202j may have any shape, but in this embodiment, it is cross-shaped like the attachment recess 202e. The shaft portion 202k is a shaft provided at the axial center position of the second attachment body 202y. The shaft portion 202k is inserted from one side to the other side of a plate-shaped holding member 220 provided on the suction tool main body 42. The shaft portion 202k is inserted into the axial center position of a driven pulley 216 of the cleaning body driving unit 48 described later, and is rotatable integrally with the driven pulley 216. Therefore, the rotary cleaning body 46 is rotatable in conjunction with the driven pulley 216 in a state in which the first attachment body 202x provided on one end side is connected to the second attachment body 202y.

[0036] The shaft portion 202k is rotatably supported at its tip by a bearing member 202z (bearing). The bearing member 202z may be rectangular (square in this embodiment) when viewed from the front and held non-rotatably by a plate-shaped holding member 202p, or the outer side (outer ring) may be held non-rotatably by the holding member 202p and the inner side (inner ring) may be rotatable. As shown in Figs. 3 and 8, the holding member 202p is held relative to the lower case 42a by being inserted into a slit-shaped insertion portion 202m provided in the lower case 42a. This allows the rotating cleaning body 46 to be stably supported.

[0037] In this embodiment, the suction tool 40 is provided with a cleaning body drive unit 48, and the rotating cleaning body 46 is driven by receiving power output from the cleaning body drive unit 48. As shown in Figures 3, 10, etc., the cleaning body drive unit 48 includes a drive machine 210, a power transmission body 212, an output side pulley 214, a driven side pulley 216, etc.

[0038] The driving machine 210 is composed of a motor and the like provided in the suction tool main body 42. The driving machine 210 is disposed in a storage section 66 provided on the rear side further than the rotating cleaning body 46 and the second dust collecting section arrangement section 64 (second dust collecting section 50). The power transmission body 212 is composed of a toothed endless belt. The output side pulley 214 is a toothed pulley attached to the output shaft of the driving machine 210.

[0039] The output pulley 214 is rotatably supported at its tip by a bearing member 214z (bearing). The bearing member 214z has a configuration similar to that of the above-mentioned bearing member 202z. Specifically, the bearing member 214z may be rectangular (square in this embodiment) when viewed from the front and held non-rotatably by a plate-shaped holding member 214p, or the outer side (outer ring) may be held non-rotatably by the holding member 214p and the inner side (inner ring) may be rotatable. As shown in FIG. 3 and FIG. 8, the holding member 214p is held by the lower case 42a by being inserted into a slit-shaped insertion portion 202n provided in the lower case 42a.

[0040] The driven pulley 216 is a toothed pulley that is integrally provided on the mounting portion 202b. The cleaning body driving portion 48 is configured by wrapping a power transmission body 212 made of an endless belt between the output pulley 214 and the driven pulley 216. Therefore, by operating the driving machine 210, the rotational power can be transmitted to the mounting portion 202b side, and the rotating cleaning body 46 can be rotated in the suction space of the suction tool main body 42.

[0041] As shown in FIG. 10 and other figures, each member constituting the cleaning body drive unit 48 is held by a holding member 220. The holding member 220 is erected in an area of ​​the suction tool body 42 on the side where the second attachment body 202y is attached. In other words, the holding member 220 is arranged side by side with the rotary cleaning body 46 in the axial direction of the rotary cleaning body 46. The holding member 220 is a plate-like member extending along the arrangement direction of the rotary cleaning body 46 and the driver 210. The output pulley 214, the driven pulley 216, and the power transmission body 212 are arranged on the opposite side of the rotary cleaning body 46 with respect to the holding member 220. As shown in FIG. 5, the holding member 220 specifically includes a lower holding member 222 and an upper holding member 224.

[0042] 10, 11, etc., lower holding member 222 has lower wall portion 222a and fixing portion 222b that fixes lower wall portion 222a to lower case 42a at the lower end side. Holding member 220 is erected so that lower wall portion 222a extends in the front-rear direction (direction from the front side to the rear side) of suction tool main body 42 by screwing lower holding member 222 to lower case 42a at fixing portion 222b. Note that fixing portion 222b is not an essential component, and it is sufficient that the configuration can structurally position lower holding member 222 in lower case 42a.

[0043] Here, the cleaning body driving part 48 will be specifically described with reference to FIG. 11. A shaft insertion hole 216a opening in a substantially oval shape is provided at the axial center position of the driven pulley 216. The shaft part 202k of the second attachment body 202y is a shaft body having a substantially oval external shape similar to the shaft insertion hole 216a. In addition, a shaft support part 220c that rotatably supports (supports) the second attachment body 202y is provided on the lower wall part 222a of the holding member 220. A bearing 225 that rotatably supports the shaft part 202k by inserting it therethrough is provided on the shaft support part 220c. Furthermore, the shaft part 202k is rotatably supported by a bearing member 202z at the tip side. Therefore, the second attachment body 202y is fixed to the driven pulley 216 with the shaft portion 202k inserted through the bearing 225 provided in the shaft support portion 220c of the lower wall portion 222a, the shaft insertion hole 216a provided in the driven pulley 216, and the bearing member 202z. Because of this configuration, by connecting the first attachment body 202x provided on the rotary cleaning body 46 side to the second attachment body 202y, the rotary cleaning body 46 can rotate in conjunction with the driven pulley 216. Therefore, the second attachment body 202y can also be expressed as being included as a part of the driven pulley 216.

[0044] At a position on the front side of the suction tool main body 42 in the lower wall 222a, a shaft support 220c is provided to rotatably support (support) the second attachment body 202y provided at the end of the rotary cleaning body 46. At a position on the rear side of the suction tool main body 42 in the lower wall 222a, a receiving portion 222d is provided that is cut out so as to be able to support the driving machine 210. Specifically, the driving machine 210 has an output shaft provided in a driving machine main body 210a forming a motor, a driving machine main body 210a1 forming the majority of the motor, and a bulging portion 210a2 that has a smaller diameter than the driving machine main body 210a1 and bulges in the axial direction. The output shaft is provided in the bulging portion 210a2.

[0045] The receiving portion 222d is formed so as to extend downward from the upper end of the lower wall portion 222a. Therefore, when the driving machine 210 is assembled, the bulging portion 210a2 can be slid along the receiving portion 222d to easily assemble the driving machine 210. If the power transmission body 212 is stretched across the output side pulley 214 and the driven side pulley 216, such assembly can be performed more easily without being difficult to do due to the tension of the power transmission body 212. In addition, since the holding member 220, the driving machine 210, the power transmission body 212, the output side pulley 214, the second mounting body 202y, the bearing 225, the driven side pulley 216, the bearing member 202z, the holding member 202p, the bearing member 214z, and the holding member 214p are unitized, the cleaning body driving unit 48 can be easily assembled into the lower case 42a. Furthermore, at a position adjacent to the receiving portion 222d, a screw hole 222e for screwing the end portion of the driving machine main body 210a1 is provided.

[0046] 5, upper holding member 224 is a plate-like portion erected relative to the upper portion (upper case 42b) of suction tool main body 42. Upper holding member 224 is provided in correspondence with a portion of lower holding member 222 where receiving portion 222d is provided. Therefore, when upper case 42b and lower case 42a are joined together to form suction tool main body 42, the upper open portion of receiving portion 222d is closed by upper holding member 224. This makes it possible to prevent driver 210 from unexpectedly falling off receiving portion 222d.

[0047] The second dust collecting section 50 collects dust introduced from the suction port 62 as the rotary cleaning body 46 rotates. The second dust collecting section 50 constitutes the dust collecting section 30 together with the first dust collecting section 24. The second dust collecting section 50 is provided at a position closer to the suction port 62 than the first dust collecting section 24 in the dust passage path connecting the first dust collecting section 24 and the suction port 62. As shown in Figs. 3 and 8, the second dust collecting section 50 is detachable from the second dust collecting section arrangement section 64 provided behind the rotary cleaning body 46 and in front of the communication section 45 described later. As shown in Figs. 8 and 12, the second dust collecting section 50 has an approximately rectangular parallelepiped appearance and is hollow. The second dust collecting section 50 is arranged in the second dust collecting section arrangement section 64 to form a hollow space extending along the axial direction of the rotary cleaning body 46 inside the suction tool main body 42.

[0048] The second dust collecting section 50 has an intake section 50a and a discharge section 50b. The intake section 50a is provided at the boundary between the second dust collecting section 50 and the rotary cleaning body arrangement section 60 in a state in which the second dust collecting section 50 is arranged in the second dust collecting section arrangement section 64. The intake section 50a is a section having an opening that can receive dust taken in from the suction port 62 into the second dust collecting section 50. The discharge section 50b is a section having an opening for leading out dust from the second dust collecting section 50. The discharge section 50b may be provided at any position of the second dust collecting section 50, but in this embodiment, it is provided at a position facing the intake section 50a. The discharge section 50b is connected to a communication section 45 that connects the joint section 44 and the second dust collecting section 50, which will be described in detail later, and is connected to an end of the communication section 45.

[0049] In addition to providing openings in the intake section 50a and the discharge section 50b as in the illustrated example, the second dust collecting section 50 may be provided with a closing member made of a shutter, a valve, or the like in either or both of the intake section 50a and the discharge section 50b. When a closing member is provided, the closing member may be in an open state when the second dust collecting section 50 is attached to the second dust collecting section mounting section 64, and the closing member may be in a closed state when the second dust collecting section 50 is removed from the second dust collecting section mounting section 64. The closing member may be electrically openable and closable, but it is preferable that the closing member be opened and closed mechanically in association with the attachment and detachment of the second dust collecting section 50 to and from the second dust collecting section mounting section 64.

[0050] For example, the closing member may be a plate-shaped shutter capable of closing the openings of the intake section 50a and the discharge section 50b, and the shutter may be biased by a biasing member such as a spring in a direction to close the opening, while a contact member may be provided to contact the shutter and push the shutter in an opening direction when the second dust collecting section 50 is inserted into the second dust collecting section 64. With this configuration, the intake section 50a and the discharge section 50b may be provided with a shutter that opens the opening when the second dust collecting section 50 is inserted into the second dust collecting section 64 and closes the opening when the second dust collecting section 50 is removed from the second dust collecting section 64. With this configuration, the second dust collecting section 50 may be configured such that the openings of the intake section 50a and the discharge section 50b are automatically opened by setting the second dust collecting section 50 in the second dust collecting section 64 and automatically closed by removing the second dust collecting section 50 from the second dust collecting section 64.

[0051] The dust removing section 54 is for removing dust adhering to the rotating cleaning body 46. As shown in FIG. 4 and FIG. 8, the dust removing section 54 is provided at the boundary between the rotating cleaning body arrangement section 60, on which the rotating cleaning body 46 rotates, and the second dust collecting section 50. The dust removing section 54 extends toward the rotating cleaning body 46. The dust removing section 54 is provided at a position where the dust removing section 54 abuts against the cleaning body 200 of the rotating cleaning body 46. The dust removing section 54 is also detachable from the suction tool body 42 as appropriate. In this embodiment, the dust removing section 54 is provided integrally with the above-mentioned second dust collecting section 50. Therefore, the dust removing section 54 is detachable from the suction tool body 42 as appropriate together with the second dust collecting section 50.

[0052] The dust removing part 54 can be, for example, in a blade shape, but in this embodiment, it is in a comb-like shape. The dust removing part 54 can efficiently scrape off dust from the surface of the rotating cleaning body 46, and is provided in a position suitable for scraping off the dust toward the second dust collecting part 50.

[0053] Specifically, the dust removal section 54 has a protrusion group 54g consisting of a plurality of protrusions 54a. The protrusions 54a are configured to protrude toward the rotary cleaning body 46 when the dust removal section 54 is installed on the suction tool main body 42. The protrusion group 54g is provided so that the plurality of protrusions 54a are aligned along the axial direction of the rotary cleaning body 46 when the dust removal section 54 is installed on the suction tool main body 42. The protrusion group 54g is also provided so that a plurality of protrusions are aligned along the rotation direction of the rotary cleaning body 46. Furthermore, the protrusion group 54g is disposed at a position downstream of the opening of the intake section 50a, which is the inlet to the second dust collecting section 50, in the rotation direction of the rotary cleaning body 46, and at a position rearward of the rotary cleaning body 46. Note that, although an example in which two sets of protrusion groups 54g are provided in the rotation direction of the rotary cleaning body 46 has been shown here, a configuration in which the protrusion amount of one protrusion group 54g is greater than the protrusion amount of the other protrusion group 54g may be used.

[0054] More specifically, the protrusions 54a constituting the protrusion group 54g are provided at a position above the opening constituting the intake portion 50a in the second dust collecting portion 50. The protrusions 54a are arranged at predetermined intervals across substantially the entire width of the opening of the intake portion 50a, and are arranged at predetermined intervals in multiple rows in the vertical direction. As a result, the protrusions 54a constituting the protrusion group 54g are arranged downstream in the rotation direction of the rotary cleaning body 46 and at a position rearward of the rotary cleaning body 46, so as to be aligned along the axial direction of the rotary cleaning body 46 and aligned along the rotation direction of the rotary cleaning body 46.

[0055] 4 and 9, a scraper 56 is provided on the bottom side of the suction tool main body 42. The scraper 56 is provided at the boundary portion of the suction port 62 so as to extend in the axial direction of the rotary cleaning body 46. The scraper 56 is provided so as to form a gap between itself and the rotary cleaning body 46 and so as to have its tip protrude toward the cleaning surface. This allows the scraper 56 to scoop up dust on the cleaning surface and collect the dust in the second dust collecting section 50. The upper surface of the scraper 56 is preferably inclined so that the upper surface approaches the cleaning surface toward the tip in order to facilitate the transfer of dust.

[0056] The current-carrying part 52 is a terminal electrically connected to the cleaning element driving part 48 via wiring arranged in the housing part 66. The terminal constituting the current-carrying part 52 is electrically connected to a terminal provided on the vacuum cleaner body 20 side by connecting the joint part 44 to the tube connection part 22b of the vacuum cleaner body 20. This allows power to be supplied from the vacuum cleaner body 20 side to the cleaning element driving part 48, causing the rotating cleaning element 46 to rotate.

[0057] <About Extension Tube 90> The extension pipe 90 is a cylindrical member that is connected to the pipe connection portion 22b of the vacuum cleaner body 20 and the joint portion 44 of the suction tool 40. As shown in Fig. 13, the extension pipe 90 has an engaged portion 310 that engages with a support portion 350 provided on a support device 300, which will be described later in detail.

[0058] 13, the engaged portion 310 is a portion that engages with an engaging portion 352 provided on the support device 300, which will be described later in detail. The engaged portion 310 may be provided integrally with the pipe that constitutes the extension pipe 90, but in this modified example, a receiving portion 312 is provided on a pipe cover 320 (the pipe cover on the suction tool 40 side of the extension pipe 90) that is attached to the pipe that constitutes the extension pipe 90. The receiving portion 312 is a hollow portion formed on the outer circumferential surface of the extension pipe 90 so as to bulge outward in the radial direction.

[0059] Receiving portion 312 has a first opening 314 that opens toward suction tool 40. Receiving portion 312 also has a second opening 316 formed to open on the back side. Specifically, second opening 316 is formed to open on a surface (contact surface 318) facing support portion 350 of supporting device 300 when installed on supporting device 300, which will be described in detail later. Receiving portion 312 also has a first current-carrying portion, which will be described later, for receiving power supply.

[0060] <Regarding the support device 300> As shown in Fig. 1, the support device 300 supports the vacuum cleaner body 20 with the extension tube 90 and the suction tool 40 attached thereto, and may have a charging function. As shown in Fig. 14, the support device 300 has a placement portion 340, a support portion 350, and a receiving portion 370.

[0061] The mounting portion 340 is a portion that serves as a base for mounting the suction tool 40. The mounting portion 340 has a stopper 342 on the front side. The stopper 342 is formed so as to protrude upward from the top surface side of the mounting portion 340. The stopper 342 is also formed so as to extend in the width direction of the mounting portion 340. Therefore, the stopper 342 can position the suction tool 40 arranged on the top surface of the mounting portion 340 so that it does not move beyond the stopper 342 to the front side.

[0062] The support part 350 is a support-shaped part erected in the vertical direction on the rear side (opposite side to the stopper 342) of the placement part 340. The support part 350 is a part that engages with and supports the extension tube 90 connected to the suction tool 40 arranged on the placement part 340. Specifically, the support part 350 can support the extension tube 90 by engaging the engaged part 310 of the extension tube 90 with the engagement part 352 provided on the upper end side. In addition, the support part 350 has a second current-carrying part that can be electrically connected to the first current-carrying part provided on the suction tool 40 side of the extension tube 90. This makes it possible to charge the battery 34 via the extension tube 90. To enable such a configuration, the extension tube 90 is provided with wiring for connecting the third current-carrying part (the third current-carrying part electrically connected to the battery 34) on the vacuum cleaner main body 20 side and the first current-carrying part. In order to supply power to the suction tool 40, an electrical current conducting section (fourth and fifth electrical current conducting sections) are provided on both the vacuum cleaner body 20 side and the suction tool 40 side of the extension tube 90, and wiring connecting the fourth electrical current conducting section (the fourth electrical current conducting section electrically connected to the battery 34) and the fifth electrical current conducting section is arranged in the extension tube 90.

[0063] As shown in FIG. 15, the engagement portion 352 has four protrusions consisting of a first protrusion 354, a second protrusion 356, a third protrusion 358, and a fourth protrusion 359. The first protrusion 354 is a protrusion-like portion provided on the front side of the support portion 350 so as to protrude from the lower side toward the upper side. The first protrusion 354 is a portion that is inserted into the receiving portion 312 through the first opening 314 provided in the extension tube 90 described above. The second protrusion 356 is provided on the inside of a space 360 ​​that is open toward the front side and the top surface side at the upper end side of the support portion 350, and is provided so as to face the first protrusion 354 with a predetermined gap therebetween. The third protrusion 358 is a protrusion-like portion that is arranged so as to intersect with the first protrusion 354. The third protrusion 358 is arranged on the inside of the space 360, similar to the second protrusion 356. In addition, the first protrusion 354 and the third protrusion 358 may be spaced apart from each other, but in this embodiment, the third protrusion 358 is connected to the first protrusion 354 at the middle part of the first protrusion 354 in the width direction. Therefore, the first protrusion 354 and the third protrusion 358 are formed in a substantially "T" shape in a plan view. In addition, the fourth protrusion 359 is provided so as to protrude toward the space 360 ​​on the surface of the first protrusion 354 facing the space 360. The fourth protrusion 359 is provided at a position facing the second protrusion 356.

[0064] The space 360 ​​is a portion in which the second protrusion 356 and the third protrusion 358 are arranged. The edge of the upper end side of the space 360 ​​is provided with a chamfered portion 360a that is chamfered, for example, in a tapered shape, in order to easily guide the receiving portion 312 provided on the extension tube 90. The opening width of the space 360 ​​on the front side is equal to or greater than the width of the receiving portion 312 provided on the extension tube 90. The first protrusion 354 described above is formed so as to rise from below to above at a position that protrudes slightly toward the front side from the opening portion on the front side of the space 360. The width of the third protrusion 358 described above is equal to or less than the width of the second opening 316 formed on the abutting surface 318 of the receiving portion 312 in the extension tube 90. The second protrusion 356 is provided on both sides of the third protrusion 358 in the width direction. Therefore, by inserting the receiving portion 312 in the extension tube 90 aiming at the space 360, the abutment surface 318 of the receiving portion 312 enters between the first protrusion 354 and the second protrusion 356, and the third protrusion 358 enters the second opening 316 provided in the abutment surface 318. As a result, the engaged portion 310 provided on the extension tube 90 side and the engaging portion 352 provided on the support portion 350 side are engaged with each other.

[0065] In the above modified example, an example is shown in which four protrusions consisting of first protrusion 354, second protrusion 356, third protrusion 358, and fourth protrusion 359 are provided as engagement portion 352. However, the present invention is not limited to this, and for example, it may be one that only has first protrusion 354, or one that does not have one or more of the protrusions other than first protrusion 354 (second protrusion 356, third protrusion 358, and fourth protrusion 359).

[0066] As shown in Fig. 14, the receiving part 370 receives the first dust collecting part 24 of the vacuum cleaner 10, thereby supporting the vacuum cleaner 10 in an upright state. The receiving part 370 is provided on the upper end side of a receiving part support 372 that is provided on the rear side of the support part 350 of the support device 300. As shown in Fig. 14, the receiving part 370 has a first dust collecting part recess 370a formed so that the lower end part of the first dust collecting part 24 fits into it. In addition, an extension tube recess 370b is provided on the periphery of the receiving part 370. The extension tube recess 370b is formed in a concave shape so as to fit into or abut against a part of the periphery of the extension tube 90 that connects the vacuum cleaner body 20 and the suction tool 40 in the vacuum cleaner 10.

[0067] 1, when the first dust collecting part 24 of the vacuum cleaner 10 is fitted into the first dust collecting part recess 370a, the receiving part support 372 is aligned with the extension tube 90 fitted into the extension tube recess 370b. Therefore, by fitting the first dust collecting part 24 into the receiving part 370 while arranging the suction tool 40 connected to the tip side of the extension tube 90 on the mounting part 340, the vacuum cleaner 10 is stably supported by the extension tube 90 and the receiving part support 372 arranged side by side. Note that instead of the extension tube recess 370b, a pipe connecting part recess that fits or abuts against a part of the periphery of the pipe connecting part 22b may be used.

[0068] The receiving portion 370 is provided with a support-side terminal 370c. The support-side terminal 370c is provided to correspond to the body-side terminal 25 provided in the vacuum cleaner 10. The support-side terminal 370c is brought into contact with the body-side terminal 25 provided in the vacuum cleaner body 20 at a position adjacent to the first dust collecting portion 24 by fitting the first dust collecting portion 24 of the vacuum cleaner 10 into the first dust collecting portion recess 370a of the receiving portion 370, and is electrically connected to the body-side terminal 25. Specifically, the body-side terminal 25 is disposed between the suction port of the pipe connection portion 22b and the connection port of the pipe connection portion 22b with the first dust collecting portion 24. Preferably, the body-side terminal 25 is provided on a surface of the support device 300 facing the bottom surface of the receiving portion 370. The body-side terminal 25 is electrically connected to the control device 32, and the control device 32 may detect the passage of electricity. It is also possible to provide the main body side terminal 25 on the extension tube 90, but this poses the problem that the extension tube 90 has the charging wiring mentioned above, making it difficult to run further wiring. By providing the main body side terminal 25 on the vacuum cleaner main body 20, the complication of running further wiring to the extension tube 25 can be avoided.

[0069] <Operation of the vacuum cleaner 10> The vacuum cleaner 10 is capable of operating in a plurality of operation modes, including a first mode, a second mode, and a third mode. In this embodiment, the operation unit 28 of the vacuum cleaner 10 functions as a mode selection receiving unit that receives a selection of an operation mode, and the vacuum cleaner 10 is capable of selecting an operation mode that is intentionally or automatically selected by performing a switching operation via the operation unit 28. The vacuum cleaner 10 can perform an operation according to the selected operation mode under the control of the control device 32 (processing execution unit).

[0070] The first mode is an operation mode in which the cleaning body drive unit 48 is driven while the driving of the electric blower 22 is stopped. In the first mode, the electric blower 22 is stopped, so no suction force is generated by the electric blower 22. On the other hand, in the first mode, the cleaning body drive unit 48 is driven, so the rotating cleaning body 46 rotates and scrapes off dust from the cleaning surface. In the first mode, dust is collected in the second dust collecting unit 50 by the rotation of the rotating cleaning body 46. In the first mode, the suction force by the electric blower 22 does not act, so the dust collected in the second dust collecting unit 50 remains in the second dust collecting unit 50.

[0071] The second mode is an operation mode in which the electric blower 22 is driven. In the second mode, the electric blower 22 is driven to generate a suction force. In addition, if dust has accumulated in the second dust collecting section 50 collected by the operation in the first mode before the operation in the second mode, the operation in the second mode can be started to collect the dust accumulated in the second dust collecting section 50 into the first dust collecting section 24 by the suction force of the electric blower 22. In addition, the second mode may drive the cleaning body driving section 48 together with the electric blower 22. As a result, the rotating cleaning body 46 is rotated by the driving of the cleaning body driving section 48, so that the dust collected by the rotating cleaning body 46 passes through the second dust collecting section 50 and is collected into the first dust collecting section 24 by the suction force. For example, the user can clean in the first mode at a time when he does not want to generate noise (at night or while the child is sleeping) and clean in the second mode at another time, so that cleaning according to the situation is possible.

[0072] The third mode is an operation mode in which dust is sucked from the second dust collecting section 50 toward the first dust collecting section 24 by driving the electric blower 22 for a predetermined time. The third mode can be performed by the user intentionally switching the operation via the operation section 28. Alternatively or in addition to this, in this embodiment, the operation in the third mode is automatically performed with the start condition being that the vacuum cleaner 10 is supported (placed) on the support device 300. The operating conditions for the operation in the third mode may include other conditions in addition to the vacuum cleaner 10 being supported (placed) on the support device 300, as in a modified example described separately later, but in this embodiment, the operation in the third mode is automatically performed when the vacuum cleaner 10 is supported (placed) on the support device 300.

[0073] Detection of the vacuum cleaner 10 being supported (placed) on the support device 300 can be realized by an appropriate method, such as providing a sensor. In this embodiment, when the first dust collecting part 24 is fitted into the first dust collecting part recess 370a of the receiving part 370, and the main body side terminal 25 and the support side terminal 370c are electrically connected, the vacuum cleaner 10 is considered to be supported (placed) on the support device 300, and operation in the third mode is automatically performed. That is, in this embodiment, the main body side terminal 25 and the support side terminal 370c function as a detection part for detecting that the vacuum cleaner 10 is supported (placed) on the support device 300, and operation in the third mode is automatically performed on the condition that it is detected that the vacuum cleaner 10 is supported (placed) on the support device 300.

[0074] <<Variations>> The above-described vacuum cleaner 10 is merely one example of the present invention, and may be configured as shown below.

[0075] Although the above-described vacuum cleaner 10 allows the mode switching operation to be performed by the operation unit 28, the present invention is not limited to this, and a voice recognition unit that accepts operations by voice recognition may be provided instead of or in addition to the operation unit 28. In such a configuration, it is preferable that the voice recognition unit recognizes a voice indicating one of a plurality of modes, and the recognized mode is switched to. In such a configuration, mode switching can be easily performed not only in a type of vacuum cleaner that is used by the user by holding it in his / her hand, such as the above-described vacuum cleaner 10, but also in a type of vacuum cleaner that operates without the user touching it, such as a so-called robot vacuum cleaner.

[0076] The above-mentioned electric vacuum cleaner 10 has been exemplified as a configuration in which the electric blower 22 is stopped in the first mode and driven in the second mode, but the present invention is not limited thereto. For example, instead of the first and second modes, or in addition to the first and second modes, a first drive mode in which the electric blower 22 is driven with a first parameter and a second drive mode in which the electric blower 22 is driven with a second parameter larger than the first parameter may be provided. In the first and second drive modes, the cleaning body drive unit 48 may be driven together with the electric blower 22. The parameter here may be the rotation speed of the electric blower 22, a value indicating the suction force by the electric blower 22, or a value indicating the negative pressure acting on the suction port 62. The electric vacuum cleaner 10 may not only control the electric blower 22 to be turned on and off, such as by switching between the first and second modes, but may also change the suction force by adjusting the output of the electric blower 22, such as in the first and second drive modes. With this configuration, the vacuum cleaner 10 performs cleaning with reduced noise associated with the operation of the electric blower 22 in the first drive mode in which the electric blower 22 operates at a first parameter (e.g., low rotation speed), while in the second drive mode in which the electric blower 22 operates at a second parameter (e.g., high rotation speed), cleaning can be performed with sufficient suction force from the electric blower 22. For example, by setting the electric blower 22 to operate with a parameter at which dust reaches the second dust collecting section 50 as the first parameter in the first drive mode and with a parameter at which dust reaches the first dust collecting section 24 as the second parameter in the second drive mode, cleaning according to the situation can be performed.

[0077] The above-mentioned electric vacuum cleaner 10 is an example of a vacuum cleaner having a stick-shaped appearance, but the present invention is not limited thereto, and it is possible to use, for example, a canister-type vacuum cleaner (a vacuum cleaner main body having a main body part and a first dust collecting part, a handle, a suction tool 40 communicating with the vacuum cleaner main body via a hose, and a configuration in which the handle and the suction tool 40 are connected via an extension tube) or a so-called robot vacuum cleaner. In addition, in the case where the vacuum cleaner main body 20 and the suction tool 40 are not separate bodies, such as a self-propelled robot vacuum cleaner, it is not necessary to provide the first dust collecting part 24 on the vacuum cleaner main body 20 and the second dust collecting part 50 on the suction tool 40 as in the electric vacuum cleaner 10, and it is also possible to provide the first dust collecting part 24 and the second dust collecting part 50 in the same housing. In this case, too, the second dust collecting part 50 is provided between the rotating cleaning body 46 and a communication part having an exhaust part 50b at its end that exhausts to the first dust collecting part 24 side.

[0078] In addition, the above-mentioned electric vacuum cleaner 10 is a vacuum cleaner having an extension tube 90 that connects the vacuum cleaner body 20 and the suction tool 40, but the present invention is not limited to this. It is also possible to have a vacuum cleaner that does not have an extension tube 90 that connects the vacuum cleaner body 20 and the suction tool 40.

[0079] In the above-described electric vacuum cleaner 10, the second dust collecting section 50 is formed so that its width is substantially the same at any point from the intake section 50a side to the discharge section 50b side, but the present invention is not limited thereto. For example, as shown in FIG. 11, the second dust collecting section 50 may be formed so that its width along the axial direction of the rotating cleaning body 46 decreases from the intake section 50a side to the discharge section 50b side. With this configuration, when the suction force of the electric blower 22 acts, dust that has flowed into the second dust collecting section 50 can be smoothly sucked from the intake section 50a side to the discharge section 50b side.

[0080] In the above embodiment, an example has been shown in which the vacuum cleaner 10 is supported by the support device 300, and the main body side terminal 25 and the support side terminal 370c are brought into contact to energize the vacuum cleaner 10, and the vacuum cleaner 10 automatically operates in the third mode. However, it is also possible to configure the vacuum cleaner 10 such that it is possible to set whether or not the vacuum cleaner 10 automatically operates in the third mode when the vacuum cleaner 10 is supported by the support device 300. Specifically, for example, as shown in FIG. 1, it is also possible to configure the vacuum cleaner 10 such that a third mode setting unit 380 for setting whether or not the vacuum cleaner 10 operates in the third mode is provided on the receiving unit 370 or on the placement unit 340 of the support device 300. In such a configuration, it is preferable to operate the vacuum cleaner 10 in the third mode under the following conditions: the third mode setting unit 380 is set to permit operation in the third mode, and the vacuum cleaner 10 is supported (placed) on the support device 300. This allows the user to set whether or not the vacuum cleaner 10 automatically operates in the third mode when the vacuum cleaner 10 is supported by the support device 300, according to the user's intention, thereby further improving convenience. The third mode setting unit 380 is, for example, a switch for switching between enabled (ON) and disabled (OFF). The third mode setting unit 380 may be provided in the vacuum cleaner .

[0081] In the above embodiment, an example was shown in which the operation in the third mode was performed with the operation condition being that the vacuum cleaner 10 was supported by the support device 300, but it is possible to provide other conditions as the operation condition for the third mode. For example, the vacuum cleaner 10 may be configured to operate in the third mode with the operation condition being that the vacuum cleaner 10 is supported by the support device 300 and that there is an operation history in which operation in either the first mode or the second mode was performed after an operation in the third mode that was previously performed. With such a configuration, it is possible to more reliably prevent dust collected by performing an operation in the first mode or the second mode from remaining in the second dust collecting section 50. The operation history may be stored in the control device 32 of the vacuum cleaner 10 or in a recording medium that the control device 32 can read or communicate with. In addition, the control device 32 may reset the operation history when the third mode is performed based on the operation history.

[0082] Furthermore, the electric vacuum cleaner 10 may have, for example, a timer setting. That is, the electric vacuum cleaner 10 may include a clock means for clocking time and a time setting means for setting the time, and when the electric vacuum cleaner 10 is placed on the support device 300, the third mode may be performed when the time clocked by the clock means reaches the set time by the time setting means.

[0083] Note that the vacuum cleaner system S may not have any of the setting of the third mode setting unit 380, the operation history, and the timer setting, or may have at least one of them as a function. Specifically, in a case where the vacuum cleaner 10 is placed on the support device 300, the system may be in an aspect 1 in which the system has any of the setting of the third mode setting unit 380, the operation history, and the timer setting, or in an aspect 2 in which the system has the setting of the third mode setting unit 380 and at least one of the operation history and the timer setting, or in an aspect 3 in which the system has the operation history and the timer setting.

[0084] The embodiment 1 is as described above. In the embodiment 2, when the setting of the third mode setting unit 380 is in an permitted state, the third mode may be executed in a state where there is an operating history, when the setting of the third mode setting unit 380 is in an permitted state, the third mode may be executed when the time set by the timer is reached, or further, when the setting of the third mode setting unit 380 is in an permitted state, the third mode may be executed when the time set by the timer is reached in a state where there is an operating history.

[0085] In the third aspect, in a case where the vacuum cleaner 10 is installed on the support device 300, the third mode may be executed when the timer setting time comes in a state where there is an operation history. On the other hand, in a case where the vacuum cleaner 10 is not installed on the support device 300, the third mode may be executed according to the timer setting, or the operation history and the timer setting. In other words, the third mode may be executed when the timer setting time comes in a state where there is an operation history, or the third mode may be executed when the timer setting time comes regardless of the presence or absence of an operation history.

[0086] Furthermore, in the above embodiment, the vacuum cleaner 10 executes the third mode in which the electric blower 22 is driven for a predetermined period of time, but the vacuum cleaner 10 may be provided with a dust detection means for detecting dust passing through the air passage communicating with the first dust collecting section 24, and the third mode in which the electric blower 22 is driven may be executed when the dust detection means detects dust.

[0087] In addition, the vacuum cleaner 10 of the above embodiment may be configured to execute the third mode before or after charging by the support device 300, and the power supplied to the electric blower 22 while the third mode is being executed may be supplied from both the battery 34 and the support device 300 (commercial power source).

[0088] As described above, the electric vacuum cleaner of the present invention is an invention that solves the problems in the technology disclosed in the above-mentioned Patent Document 1 (Japanese Utility Model Publication No. 53-134769). That is, the above-mentioned Patent Document 1 provides a vacuum cleaner that includes a rotating brush, an electric motor that drives the rotating brush, a transmission device that transmits the power of the electric motor to the rotating brush, and a dust collection box with a dust inlet on the surface facing the rotating brush, and an opening on the underside of the rotating brush. When the vacuum cleaner is configured as disclosed in Patent Document 1, with the rotating brush and the electric motor as well as the dust collection box in the main body and without the electric blower, noise caused by the driving of the electric blower is not generated, so that it is possible to suppress noise during cleaning. However, when a vacuum cleaner is configured without an electric blower that generates suction power, as in the vacuum cleaner of Patent Document 1, there is a problem that it is difficult to draw in dust adhering to a rug or carpet, for example, into the main body. SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a vacuum cleaner that can selectively use either cleaning that utilizes the suction force of an electric blower or cleaning that utilizes the rotation of a rotating brush.

[0089] The vacuum cleaner 10 according to the above-described embodiment and modified examples is an embodiment of the inventions according to the following items (1-1) to (1-14). According to the inventions according to the following items (1-1) to (1-14), for example, the following effects can be obtained.

[0090] (1-1) The electric vacuum cleaner of the present invention comprises an electric blower that generates suction force, a dust collecting section that collects dust, an inlet for sucking in dust, and a rotating cleaning body that rotates by driving a drive section, wherein the dust collecting section has a first dust collecting section and a second dust collecting section that is arranged on the suction port side of the first dust collecting section in a path connecting the first dust collecting section and the suction port, and is characterized in that it is switchable between one of a plurality of operating modes including a first mode in which the drive section is driven with the electric blower stopped, and a second mode in which the electric blower is driven.

[0091] The vacuum cleaner of the present invention can be used in a first mode to rotate the rotary cleaning body for cleaning without generating the driving noise of the electric blower by driving the cleaning body drive unit while stopping the driving of the electric blower. Also, the vacuum cleaner of the present invention has a dust collection unit that includes, in addition to the first dust collection unit, a second dust collection unit that is disposed on the suction port side of the first dust collection unit. Therefore, when the vacuum cleaner of the present invention is operated in the first mode in which the suction force is not generated by the electric blower, dust collected by the rotation of the rotary cleaning body can be collected in the second dust collection unit.

[0092] On the other hand, the vacuum cleaner of the present invention can perform cleaning using the suction force of the electric blower by driving the electric blower in the second mode. Also, the vacuum cleaner of the present invention has a first dust collecting section at a position away from the second dust collecting section in a direction away from the suction port (suction direction). Therefore, the vacuum cleaner of the present invention can collect dust collected in the second dust collecting section by operation in the first mode in the first dust collecting section by the suction force of the electric blower.

[0093] As described above, the vacuum cleaner of the present invention has a dust collecting section that includes a first dust collecting section and a second dust collecting section, and is operable in a plurality of modes including a first mode and a second mode, whereby the vacuum cleaner of the present invention can selectively use cleaning that utilizes the suction force of the electric blower and cleaning that utilizes the rotation of the rotating brush.

[0094] (1-2) The vacuum cleaner of the present invention is preferably one that can be installed on a support device provided separately from the vacuum cleaner, and is characterized in that, when installed on the support device, it operates in a third mode in which the electric blower is driven to suck dust toward the first dust collecting section.

[0095] The electric blower is driven on the condition that the vacuum cleaner of the present invention is placed on the support device. Therefore, the vacuum cleaner of the present invention can keep the second dust collecting section clean by operating in the third mode. In other words, it is possible to prevent excessive accumulation of dust in the second dust collecting section.

[0096] (1-3) The vacuum cleaner of the present invention may be one that can be installed on a support device provided separately from the vacuum cleaner, and is characterized in that, when installed on the support device and satisfies one or more other conditions, it operates in a third mode in which it drives the electric blower to suck dust toward the first dust collecting section.

[0097] The vacuum cleaner of the present invention, having the above-mentioned configuration (1-3), can keep the second dust collecting section clean. In other words, it is possible to prevent excessive accumulation of dust in the second dust collecting section.

[0098] (1-4) As in the above-described modified example, the vacuum cleaner of the present invention is preferably characterized in that the support device or the vacuum cleaner is provided with a third mode setting unit that sets whether or not to operate in the third mode, and the vacuum cleaner is operated in the third mode with the other condition being that the third mode setting unit is set to permit operation in the third mode.

[0099] By configuring the vacuum cleaner of the present invention as described above in (1-4), when the vacuum cleaner 10 is placed on the support device 300, the user can set whether or not to automatically operate in the third mode according to his or her intention, thereby further improving convenience.

[0100] (1-5) It is preferable that the vacuum cleaner of the present invention, as in the above-described modified example, is characterized in that it operates in the third mode with the other condition being that there is an operating history in which operation in either the first mode or the second mode has been performed after a previous operation in the third mode.

[0101] By being configured as described above in (1-5), the vacuum cleaner of the present invention can more reliably prevent dust collected by operating in the first mode or the second mode from remaining accumulated in the second dust collecting section 50.

[0102] (1-6) The vacuum cleaner of the present invention may further include a detection unit that detects that the vacuum cleaner is placed on the support device.

[0103] The vacuum cleaner of the present invention can detect that it is placed on the support device by being configured as described above in (1-6). Note that, in the above embodiment, the main body side terminal 25 provided on the vacuum cleaner 10 and the support side terminal 370c provided on the support device 300 function as the detection unit, but the present invention is not limited to this, and for example, various sensors, switches, etc. may be used as the detection unit.

[0104] (1-7) The electric vacuum cleaner of the present invention may preferably be characterized by comprising a vacuum cleaner body having the electric blower and the first dust collecting section, and a suction tool having the suction port, the second dust collecting section, the drive section, and the rotating cleaning body.

[0105] The vacuum cleaner of the present invention, by being configured as described above in (1-7), can rotate the rotating cleaning body to clean and collect dust in the second dust collecting section of the suction tool without generating driving noise from the electric blower when operated in the first mode. Also, by being configured as described above in (1-7), the vacuum cleaner of the present invention, by being configured as described above in (1-7), can perform cleaning using the suction force of the electric blower when operated in the second mode, and can also perform an operation in which the dust collected in the second dust collecting section by operation in the first mode is collected in the first dust collecting section.

[0106] (1-8) The vacuum cleaner of the present invention may preferably be characterized in that it comprises a detection unit provided in the vacuum cleaner body for detecting that the vacuum cleaner is placed on the support device by electrical connection with the support device, and an extension tube connecting the vacuum cleaner body and the suction tool, and that a battery provided in the vacuum cleaner body can be charged by supplying power from the support device via an electrical connection provided in the extension tube. The vacuum cleaner of the present invention, by being configured as described above in (1-8), can detect the installation on the support device. Also, by being configured as described above in (1-8), the vacuum cleaner of the present invention can supply power from the support device via a conductive part provided on the extension tube to charge the battery provided in the vacuum cleaner body. Furthermore, by providing the detection part on the vacuum cleaner body as described above in (1-8), the vacuum cleaner of the present invention does not need to provide wiring connected to the detection part on the extension tube.

[0107] (1-9) In the vacuum cleaner of the present invention, it is preferable that the support device includes a receiving part that supports the first dust collecting part and a detection part that detects that the vacuum cleaner has been installed, and the detection part is provided on the receiving part and detects that the vacuum cleaner has been installed when the first dust collecting part is supported by the receiving part.

[0108] By configuring the vacuum cleaner of the present invention as described above in (1-9), the first dust collecting part is installed in the receiving part, which improves the stability of support relative to the support device, thereby improving the detection accuracy.

[0109] (1-10) The vacuum cleaner of the present invention may be one that can be installed on a support device provided separately from the vacuum cleaner, and is characterized by including an instruction receiving unit that receives an instruction to operate in a third mode in which the electric blower is driven by contact with the support device to suck dust toward the first dust collecting unit. For example, the instruction receiving unit may be a switch that executes the third mode, and the third mode may be executed by a part of the support device (e.g., a protrusion) contacting or pressing the switch.

[0110] The vacuum cleaner of the present invention can also be provided with an instruction receiving unit instead of a detection unit consisting of a sensor or the like, as described above (1-10), so that it can be operated in the third mode to clean the second dust collecting section, provided that the vacuum cleaner is placed on the support device.

[0111] (1-11) The vacuum cleaner of the present invention may preferably be characterized in that it comprises a timing means for timing a time and a time setting means for setting the time, and performs the third mode with the other condition being that the time measured by the timing means becomes the time measured by the time setting means.

[0112] The vacuum cleaner of the present invention can execute the third mode at a timing desired by the user, as described above in (1-11). The clock means and the time setting means may be applied to the configuration described above in (1-1) to execute the third mode in which the time measured by the clock means becomes the time measured by the time setting means.

[0113] (1-12) In the electric vacuum cleaner of the present invention, it is preferable that the third mode is a mode in which the electric blower is driven for a predetermined time, or a mode in which the electric blower is driven when dust is detected by dust detection means that detects the passage of dust in an air passage communicating with the first dust collecting section.

[0114] The vacuum cleaner of the present invention can improve noise reduction by limiting the time for which the electric blower is driven, as described above in (1-12).

[0115] (1-13) The vacuum cleaner of the present invention preferably has a mode selection receiving unit (operation unit 28) that receives a selection of the operation mode, and a process execution unit (control device 32) that, when a selection of an operation mode is received by the mode selection receiving unit, executes an operation related to the received operation mode, and is characterized in that the operation modes that can be received for selection by the mode selection receiving unit include a third mode in which the electric blower is driven to suck dust toward the first dust collecting unit.

[0116] The vacuum cleaner of the present invention, by being configured as described above in (1-13), can cause the process execution unit to execute an operation in the third mode when the third mode is intentionally selected as the operation mode in the mode selection receiving unit. Therefore, by being configured as described above in (1-13), the vacuum cleaner of the present invention can operate in the third mode according to the user's intention, and can keep the second dust collecting unit clean.

[0117] (1-14) The vacuum cleaner of the present invention is preferably one that can be installed on a support device having a charging mechanism provided separately from the vacuum cleaner, and is characterized in that it operates in a third mode in which the electric blower is driven by power supplied from a battery and the support device (commercial power source).

[0118] By configuring the vacuum cleaner of the present invention as described above in (1-14), it becomes possible to drive the electric blower with power supplied from the support device even when the battery is low in charge. Note that the vacuum cleaner may be configured to supply power from the support device when the battery charge is equal to or less than a threshold, and not to supply power from the support device when the battery charge is greater than the threshold.

[0119] Here, the vacuum cleaner disclosed in Patent Document 1 (Japanese Utility Model Publication No. 53-134769) is equipped with a dust collection box in the main body along with a rotating brush and an electric motor, and since it does not have an electric blower, no noise is generated by driving, making it possible to suppress noise during cleaning. Although this conventional technology employs a configuration equipped with a dust remover, there was a problem that maintenance was difficult.

[0120] SUMMARY OF THE PRESENT EMBODIMENTS Accordingly, an object of the present invention is to provide a vacuum cleaner with improved maintainability of the dust removal section.

[0121] In order to achieve this object, the vacuum cleaner 10 according to the above-described embodiment and modified example embodies the following inventions according to (2-1) to (2-6). According to the following inventions according to (2-1) to (2-6), for example, the following effects can be obtained.

[0122] (2-1) The vacuum cleaner of the present invention is characterized in that it comprises a main body (corresponding to the suction tool main body 42 in the above embodiment) having a dust collecting section (corresponding to the second dust collecting section 50 in the above embodiment) for collecting dust, a suction port for sucking in dust, and a rotating cleaning body that rotates when driven by a drive unit, and a dust removing section for removing dust attached to the rotating cleaning body, the dust removing section being detachably provided on the main body. Note that the main body of the vacuum cleaner in this case may include a configuration in which it communicates with an electric blower, or a configuration in which it is not connected to a vacuum cleaner main body having an electric blower.

[0123] In the vacuum cleaner of the present invention, as described above in (2-1), the dust removal unit is detachable from the main body, making it easy to perform maintenance on the dust removal unit.

[0124] (2-2) The vacuum cleaner of the present invention may be characterized in that the main body portion includes an opening through which the dust collection portion is detachably attached to the main body portion, a cover portion for opening and closing the opening, and a biasing member for biasing the cover portion in a direction to open the opening.

[0125] By configuring the vacuum cleaner of the present invention as described above in (2-2), the cover can be opened and closed to easily attach and detach the dust collecting unit.

[0126] (2-3) The vacuum cleaner of the present invention may be characterized in that the dust removal section has a plurality of protrusions protruding toward the rotating cleaning body and a group of protrusions aligned along the axial direction of the rotating cleaning body.

[0127] The vacuum cleaner of the present invention, by being configured as described above in (2-3), can clean each part of the rotary cleaning body in the axial direction by the projections forming the projection group.

[0128] (2-4) In the vacuum cleaner of the present invention, it is preferable that the projections constituting the projection group are arranged in a plurality of rows along the rotation direction of the rotary cleaning body.

[0129] By being configured as described above in (2-4), the vacuum cleaner of the present invention can increase the frequency with which the rotary cleaning body comes into contact with dust adhering to the rotary cleaning body during one rotation by the number of protrusions aligned in the rotation direction of the rotary cleaning body. Therefore, by being configured as described above in (2-4), the vacuum cleaner of the present invention can improve the dust removal ability of the dust removal part.

[0130] (2-5) The vacuum cleaner of the present invention may be characterized in that the dust collection unit is attached to the rear of the rotating cleaning body, and the dust removal unit is located at an inlet of the dust collection unit, downstream in the rotational direction of the rotating cleaning body, and rearward of the rotating cleaning body.

[0131] By being configured as described above in (2-5), the vacuum cleaner of the present invention can remove dust from the rotary cleaning body at the inlet side of the dust collecting part and smoothly collect it in the dust collecting part.

[0132] (2-6) The electric vacuum cleaner of the present invention may be characterized in that the main body is a suction tool that communicates with a vacuum cleaner main body having an electric blower.

[0133] By configuring the electric vacuum cleaner of the present invention as described above in (2-6), it is possible to use the electric vacuum cleaner by rotating the rotating cleaning body to clean without generating the driving noise of the electric blower by driving the drive unit provided in the suction tool while stopping the driving of the electric blower provided in the vacuum cleaner body.

[0134] Here, the vacuum cleaner disclosed in Patent Document 1 (Japanese Utility Model Publication No. 53-134769) has a dust collection box in the main body along with a rotating brush and an electric motor, and since it does not have an electric blower, no noise is generated by driving, making it possible to reduce noise during cleaning. However, since this conventional vacuum cleaner does not use the suction of an electric blower, there is a problem that it is difficult to take in dust that has adhered to a rug or carpet, for example, into the main body.

[0135] SUMMARY OF THE PRESENT EMBODIMENTS Accordingly, an object of the present invention is to provide a vacuum cleaner capable of cleaning while suppressing noise caused by driving the electric blower.

[0136] In order to achieve this object, the vacuum cleaner 10 according to the above-described embodiment and modified example employs the configuration as shown in (3-1). As a result, the vacuum cleaner 10 can obtain the effects described below.

[0137] (3-1) The electric vacuum cleaner of the present invention comprises an electric blower (electric blower 22) that generates suction force, a dust collecting section in which dust is collected, an inlet for sucking in dust, and a rotating cleaning body that rotates by driving a drive section, and the dust collecting section has a first dust collecting section and a second dust collecting section that is arranged on the suction port side of the first dust collecting section in a path connecting the first dust collecting section and the suction port, and is characterized in that it is switchable between one of a plurality of operating modes including a first drive mode in which the electric blower is driven with a first parameter and a second drive mode in which the electric blower is driven with a second parameter larger than the first parameter.

[0138] The vacuum cleaner 10 having such a configuration can perform cleaning with reduced noise caused by the operation of the electric blower in the first drive mode in which the electric blower operates with the first parameters, while cleaning can be performed with sufficient suction force from the electric blower in the second drive mode in which the electric blower operates with the second parameters, thereby enabling cleaning with reduced noise caused by the operation of the electric blower.

[0139] Moreover, the above-mentioned configurations (1-2) to (1-14) can be applied to the above-mentioned configuration (3-1).

[0140] The present invention is not limited to the configurations described in the above-mentioned embodiments, and appropriate design modifications and the like are possible within the scope of the technical idea of ​​the present invention. The components of the above-mentioned embodiments and modifications may be arbitrarily selected and combined. Any component of each embodiment or modification may be arbitrarily combined with any component described in the means for solving the invention, the mode for carrying out the invention, etc., or any component that embodies any component described in the means for solving the invention, the mode for carrying out the invention, etc. The present invention also intends to obtain rights to these in this application or in a divisional application based on this application.
