Summary of the Invention

Problems to be Solved by the Invention

[0004] Here, the vacuum cleaner disclosed in Patent Document 1 (Japanese Utility Model Publication No. 53-134769) includes a dust collection box in the main body together with a rotary brush and an electric motor, and since it does not have an electric blower, the noise generated by driving does not occur, and it is possible to suppress the noise during cleaning. However, such a conventional vacuum cleaner has a problem that it is difficult to take in dust attached to, for example, a plush carpet or a carpet into the main body because it does not utilize the suction of the electric blower.

[0005] Therefore, an object of the present invention is to realize a vacuum cleaner capable of performing cleaning while suppressing the generation of noise due to the driving of an electric blower.

Means for Solving the Problems

[0006] The vacuum cleaner of the present invention includes an electric blower that generates a suction force, a dust collection unit where dust is collected, a suction port for sucking in dust, and a rotating cleaning body that rotates by the drive of a drive unit. The dust collection unit has a first dust collection unit and a second dust collection unit arranged closer to the suction port side than the first dust collection unit in a path connecting the first dust collection unit and the suction port. It is characterized in that it can be switched to any one of a plurality of operation 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.

[0007] In the vacuum cleaner adopting such a configuration, in the first drive mode where the electric blower operates with the first parameter, while performing cleaning with the noise associated with the drive of the electric blower suppressed, in the second drive mode where the electric blower operates with the second parameter, cleaning can be performed in a state where the suction force by the electric blower sufficiently acts. Therefore, it becomes possible to perform cleaning while suppressing the generation of noise due to the drive of the electric blower.

Effect of the Invention

[0008] According to the present invention, it is possible to realize a vacuum cleaner capable of performing cleaning while suppressing the generation of noise due to the drive of an electric blower.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, the electric vacuum cleaner 10 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings schematically show each part of the electric vacuum cleaner 10 and are not necessarily drawn at an accurate ratio of sizes. Also, in the drawings, the same components are denoted by the same reference numerals. In this specification, terms indicating positional relationships such as up and down, left and right, front and rear, etc. are described based on the state where the electric vacuum cleaner 10 is installed upright as shown in FIG. 1 unless otherwise specified. In the following description, after describing the configuration of the electric vacuum cleaner 10, the operation of the electric vacuum cleaner 10 will be described.

[0011] ≪Configuration of Electric 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, etc., but in this embodiment, it is a rechargeable vacuum cleaner. As shown in Fig. 1, the vacuum cleaner 10 includes a cleaner body 20, a suction tool 40, and an extension pipe 90. Further, the vacuum cleaner 10 constitutes a vacuum cleaner system S in combination with a separately provided support device 300. The vacuum cleaner 10 is configured to be installable while being supported by the support device 300. Note that the "installation" is not limited to the operation of the user supporting the vacuum cleaner 10 on the support device 10 when the vacuum cleaner 10 is a stick type or a canister type, and when the vacuum cleaner 10 is a robot vacuum cleaner, it may also include the operation of self-running and connecting to the support device 300. Hereinafter, the configuration of each part will be described in more detail.

[0012] <<Regarding the cleaner body 20>> The cleaner body 20 forms the main body of the vacuum cleaner 10 and is a part that exhibits the function of generating suction force and collecting dust. Specifically, the cleaner body 20 includes a housing (main body part) 20a having an electric blower 22 for generating suction force, and a first dust collection part 24 for collecting dust contained in the sucked air.

[0013] The first dust collection part 24 captures and collects the dust that has reached from the suction tool 40 side. The first dust collection part 24 may be provided as a part of the main body part 20a, or may be detachably provided separately from the main body part 20a. Further, the first dust collection part 24 is preferably, for example, a so-called paper pack type or a so-called cyclone type. In this embodiment, the first dust collection part 24 is of the cyclone type. In addition to the electric blower 22 and the first dust collection part 24, the cleaner body 20 includes, for example, a drive circuit for driving the electric blower 22 and other electronic components, a control device 32 for controlling the operation of the vacuum cleaner 10, a battery 34 for supplying power, and other components in the main body part 20a.

[0014] In addition, the cleaner main body 20 is provided with a gripping portion 26 and an operation portion 28 on the handle. The gripping portion 26 is a portion provided for the user of the electric cleaner 10 to grip the cleaner main body 20. That is, the electric cleaner 10 can hold the cleaner main body 20 by, for example, gripping the gripping portion 26. Further, the operation portion 28 is for operating the electric cleaner 10. By providing the operation portion 28 on the gripping portion 26 as shown in FIG. 1, for example, the user can operate it while gripping the gripping portion 26.

[0015] In addition, the cleaner main body 20 has a pipe connection portion 22b in the main body portion 20a. The pipe connection portion 22b is a portion to which a hollow extension pipe 90 connecting the cleaner main body 20 and the suction tool 40 is connected. Further, the pipe connection portion 22b communicates with the first dust collection portion 24. Therefore, by connecting the joint portion 44 of the suction tool 40 to the pipe connection portion 22b via the extension pipe 90, a path connecting the suction tool 40 side and the first dust collection portion 24 is formed.

[0016] ≪Regarding the suction tool 40≫ The suction tool 40 is for sucking air and dust from the outside. As shown in FIG. 2, the suction tool 40 has a suction tool main body portion 42 (main body portion) and a joint portion 44. Further, as shown in FIG. 3, the suction tool 40 has a rotary cleaning body 46, a cleaning body drive portion 48 (drive portion), and a second dust collection portion 50 inside the suction tool main body portion 42. In addition to these, the suction tool 40 is provided with an energization portion 52 and the like.

[0017] The suction tool main body portion 42 is a portion that is placed on the floor during cleaning and has a shape that is long in the left - right direction with respect to the front - rear direction, which is the direction of operation by the user during cleaning. As shown in FIGS. 3 to 5, the suction tool main body portion 42 has a rotary cleaning body placement portion 60, a suction port 62, a second dust collection portion placement portion 64, and a storage portion 66.

[0018] The rotary cleaning body placement portion 60 is a portion where the rotary cleaning body 46 is arranged. The rotary cleaning body placement portion 60 extends in the left - right direction of the suction tool main body portion 42 and has a hollow space capable of accommodating the rotary cleaning body 46.

[0019] The suction port 62 is a portion that is opened on the bottom surface side of the suction tool main body 42 for sucking dust. In the present embodiment, a rotary cleaning body arrangement portion 60 is provided in the suction space where the suction port 62 is formed.

[0020] As shown in FIGS. 3 to 5, the second dust collection portion arrangement portion 64 is a portion where the second dust collection portion 50, which will be described in detail later, is arranged. The second dust collection portion arrangement portion 64 is configured such that the second dust collection portion 50 can be arranged at a position closer to the suction port 62 than the first dust collection portion 24 in the dust passage route connecting the first dust collection portion 24 and the suction port 62.

[0021] As can be understood with reference to FIGS. 4, 6, and 7, the second dust collection portion arrangement portion 64 includes an opening portion 64a, a cover portion 64b, a biasing member 64c, and a locking portion 64d. The opening portion 64a is an opening provided so that the second dust collection portion 50 can be inserted into and removed from the top surface of the suction tool main body 42. The opening portion 64a is a rectangular opening formed to extend in the longitudinal direction (left - right direction) of the suction tool main body 42 along the rotary cleaning body arrangement portion 60 (rotary cleaning body 46). Further, the cover portion 64b is a lid - shaped member that opens and closes the opening portion 64a. The cover portion 64b is rotatably supported by a hinge or the like on one side in the short - hand direction (front - rear direction) of the opening portion 64a. Also, the biasing member 64c biases the cover portion 64b in the direction of opening the opening portion 64a. In the present embodiment, the biasing member 64c is constituted by a torsion spring and is arranged on the rotation fulcrum side of the cover portion 64b. Further, the locking portion 64d is for closing the cover portion 64b so that it does not open. In the present embodiment, the locking portion 64d is provided on the top surface side of the suction tool main body 42 on the side opposite to the side where the biasing member 64c is provided (the free end side of the cover portion 64b) so as to be exposed.

[0022] Since the second dust collection unit arrangement portion 64 is configured as described above, by releasing the lock portion 64d, the free end side of the cover portion 64b is biased so as to spring up by the biasing force of the biasing member 64c. As a result, as shown in FIGS. 6 and 7, the second dust collection unit arrangement portion 64 is in a state where the opening portion 64a is open, and the second dust collection unit 50, which will be described in detail later, can be taken in and out. Further, when the free end side of the cover portion 64b is pushed into the top surface side of the suction tool main body portion 42 against the biasing force of the biasing member 64c and the opening portion 64a is closed by the cover portion 64b, the lock portion 64d prevents the cover portion 64b from springing up, so that the opening portion 64a can be closed as shown in FIG. 2.

[0023] As shown in FIG. 3, the accommodating portion 66 is for accommodating a drive machine 210 that forms a cleaning body drive portion 48, which will be described in detail later, and wiring for supplying power to the drive machine 210. The accommodating portion 66 is configured such that the drive machine 210 and the wiring can be arranged at a position deviated from the dust passage path. In the present embodiment, the accommodating portion 66 is provided at a position on the side opposite to the rotary cleaning body 46 with respect to the second dust collection unit 50 (behind the second dust collection unit 50).

[0024] The joint portion 44 is provided so as to communicate with the second dust collection unit 50 via the communication portion 45 at a position on the back side of the suction tool main body portion 42 of the electric vacuum cleaner 10 described above (a position on the side opposite to the rotary cleaning body 46 with respect to the second dust collection unit 50). The joint portion 44 is rotatably attached to the suction tool main body portion 42 within a predetermined rotation range (at least one of the front-rear direction and the left-right direction). The joint portion 44 is a portion to which the extension pipe 90 is connected, similar to the pipe connection portion 22b of the cleaner main body 20 described above. The joint portion 44 is cylindrical and communicates with the second dust collection unit 50 at the base end portion.

[0025] As shown in FIG. 3 and the like, the rotary cleaning body 46 is a cylindrical member that is housed in the rotary cleaning body arrangement portion 60 of the suction tool main body portion 42 and is rotatably supported. The rotary cleaning body 46 receives power from a cleaning body drive portion 48, which will be described in detail later, and is rotatable in the rotary cleaning body arrangement portion 60. The rotary cleaning body 46 includes a cleaning body main body 200 that extends in the longitudinal direction (left - right direction) of the suction tool main body portion 42, and attachment portions 202.

[0026] The attachment portion 202 is a portion used to attach the rotary cleaning body 46 to the suction tool main body portion 42. The attachment portions 202 are attached to the cleaning body main body 200 as separate members on one side and the other side in the longitudinal direction of the cleaning body main body 200, but they may be integrated with the cleaning body main body 200. The rotary cleaning body 46 is rotatably supported with respect to the suction tool main body portion 42 by attaching the attachment portions 202, 202 provided at both ends (hereinafter, the two may be distinguished as "attachment portion 202a" and "attachment portion 202b" as necessary) to predetermined attachment positions provided in the suction tool main body portion 42.

[0027] Specifically, as shown in FIG. 10(a), the attachment portion 202a has an end portion 205 having a prismatic shape (a substantially square cross - sectional shape) at one end side in the axial direction of the rotary 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 main body 200 (flange portion 207a).

[0028] Here, as shown in FIGS. 8 and 9, the receiving portion 42c on the suction tool main body portion 42 that is the attachment target of the attachment portion 202a of the rotary cleaning body 46 is separable into a lower receiving portion 42x and an upper receiving portion 42y. The lower receiving portion 42x is detachable on the back side of the suction tool main body portion 42. Specifically, as shown in FIG. 9, in the portion where the upper receiving portion 42y is formed, an upper engaging portion 42p is provided on the front side (upper side in the illustrated state) of the suction tool main body portion 42, and a concave upper engaged portion 42q is provided on the back side (lower side in the illustrated state). Further, 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 portion 42x is provided with a claw portion 42t, and the lower engaging portion 42s can be swung. Due to such a configuration, after engaging the lower engaged portion 42r with the upper engaging portion 42p, the lower receiving portion 42x can be attached to the upper receiving portion 42y by inserting and engaging the lower engaging portion 42s with the upper engaged portion 42q. Conversely, when removing the lower receiving portion 42x from the upper receiving portion 42y, by operating the claw portion 42t, first, the engagement between the lower engaging portion 42s and the upper engaged portion 42q is released. Then, the lower receiving portion 42x can be removed from the upper receiving portion 42y by removing the lower engaged portion 42r from the upper engaging portion 42p. Further, the upper receiving portion 42y is provided inside the suction tool main body portion 42. By attaching the lower receiving portion 42x to the back side of the suction tool main body portion 42, the receiving portion 42c can be formed.

[0029] As shown in FIG. 8, the upper receiving portion 42y has an upper end fitting portion 42h, an upper flange fitting portion 42i, and an upper shaft support portion 42j. The upper end fitting portion 42h is a portion opened toward the bottom surface side of the suction tool main body portion 42 so that the above-described prismatic end portion 205 can be fitted. Further, the upper flange fitting portion 42i is a portion opened toward the bottom surface side of the suction tool main body portion 42 so that the flange portion 207a can be fitted. The upper shaft support portion 42j is a portion curved in an arc shape along the shaft forming the attachment portion 202a.

[0030] As shown in FIGS. 8 and 9, the lower receiving portion 42x has a lower end contact portion 42k and a lower shaft support portion 42l at positions corresponding to the above-described upper end fitting portion 42h and upper shaft support portion 42j, respectively. The lower end contact portion 42k is a block-shaped portion formed to contact the outer peripheral surface (one side) of the end portion 205 from the cleaning surface side. By the upper end fitting portion 42h contacting the other outer peripheral surfaces (three sides) of the end portion 205, the end portion 205 is fixed to the suction tool main body portion 42. Further, the lower shaft support portion 42l is curved along the shaft forming the mounting portion 202a in the same manner as the upper shaft support portion 42j. The rotary cleaning body 46 can incorporate the end portion 205 side into the suction tool main body portion 42 by fitting the end portion 205 and the flange portion 207a into the upper end fitting portion 42h and the upper flange fitting portion 42i, respectively, and then mounting the lower receiving portion 42x on the upper receiving portion 42y.

[0031] On the other hand, as shown in FIG. 10, the mounting portion 202b supports the end portion on the other end side in the axial direction of the rotary cleaning body 46 (the side opposite to the mounting portion 202a). The mounting portion 202b includes a first mounting body 202x that can be connected to a second mounting body 202y described later. The first mounting body 202x is fixed to the end portion of the cleaning body main body 200. The second mounting body 202y is provided on the driven-side pulley 216 described later and is disposed on the side of the suction tool main body portion 42 (lower case 42a). The first mounting body 202x and the second mounting body 202y are connectable and separable in the axial direction.

[0032] 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 face of the first mounting body 202x. The shape of the mounting recess 202e may be any shape, but in the present embodiment, it is cross-shaped. The mounting recess 202e is a portion into which the mounting convex portion 202j of the second mounting body 202y described later can be fitted and engaged. The first flange portion 202i is provided so as to bulge outward in the radial direction at the end portion (the end portion on the side of the second mounting body 202y) of the first mounting body 202x.

[0033] As shown in FIGS. 10 and 11, the second attachment body 202y has an attachment convex portion 202j and a shaft portion 202k. The attachment convex portion 202j protrudes in the axial direction at the end of the second attachment body 202y and is engageable with the above-described attachment concave portion 202e. The shape of the attachment convex portion 202j may be any shape, but in this embodiment, it has a cross-shaped shape similar to that of the attachment concave portion 202e. The shaft portion 202k is a shaft body 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 portion 42. The shaft portion 202k is inserted through the axial center position of the driven pulley 216 of the cleaning body drive portion 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 where the first attachment body 202x provided at one end side is connected to the second attachment body 202y.

[0034] Further, the shaft portion 202k is rotatably supported by a bearing member 202z (bearing) at the tip side. The bearing member 202z may be non-rotatably held with respect to a plate-shaped holding member 202p having a rectangular shape (square in this embodiment) when viewed from the front, or the outer side (outer ring) may be non-rotatably held by the holding member 202p and the inner side (inner ring) may be rotatable. Also, as shown in FIGS. 3 and 8, the holding member 202p is held with respect to the lower case 42a by being inserted into a slit-shaped insertion portion 202m provided in the lower case 42a. For this reason, the rotating rotary cleaning body 46 can be stably supported.

[0035] In this embodiment, the suction tool 40 is provided with a cleaning body drive portion 48, and the rotary cleaning body 46 is driven by receiving the power output from the cleaning body drive portion 48. As shown in FIGS. 3, 10, etc., the cleaning body drive portion 48 includes a drive machine 210, a power transmission body 212, an output side pulley 214, a driven side pulley 216, etc.

[0036] The drive unit 210 is composed of a motor or the like provided within the suction tool main body 42. The drive unit 210 is disposed in a housing portion 66 provided on the back side further than the rotary cleaning body 46 and the second dust collection portion arrangement portion 64 (second dust collection portion 50). Also, the power transmission body 212 is composed of a toothed endless belt. Further, the output side pulley 214 is a toothed pulley attached to the output shaft of the drive unit 210.

[0037] The output side pulley 214 is pivotally supported by a bearing member 214z (bearing) on the tip side so as to be rotatable. The bearing member 214z has the same configuration as the above-described bearing member 202z. Specifically, the bearing member 214z may be non-rotatably held with respect to a plate-shaped holding member 214p that is rectangular (square in this embodiment) when viewed from the front, or the outer side (outer ring) may be non-rotatably held by the holding member 214p and the inner side (inner ring) may be rotatable. Also, as shown in FIGS. 3 and 8, the holding member 214p is held with respect to the lower case 42a by being inserted into a slit-shaped insertion portion 202n provided in the lower case 42a.

[0038] The driven side pulley 216 is a toothed pulley integrally provided on the attachment portion 202b. The cleaning body drive unit 48 is configured such that a power transmission body 212 formed of an endless belt is looped between the output side pulley 214 and the driven side pulley 216. Therefore, by operating the drive unit 210, rotational power can be transmitted to the attachment portion 202b side, and the rotary cleaning body 46 can be rotationally driven within the suction space of the suction tool main body 42.

[0039] Also, as shown in FIG. 10 and the like, each member forming the cleaning body driving unit 48 is held by the holding member 220. The holding member 220 is erected in a region on the side of the suction tool main body 42 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. Further, the holding member 220 is a plate-like member extending along the arrangement direction of the rotary cleaning body 46 and the drive machine 210. The output side pulley 214, the driven side pulley 216, and the power transmission body 212 are arranged on the side of the holding member 220 opposite to the rotary cleaning body 46. Also, as shown in FIG. 5, specifically, the holding member 220 has a lower holding member 222 and an upper holding member 224.

[0040] As shown in FIG. 10, FIG. 11, etc., the lower holding member 222 has a lower wall portion 222a and a fixing portion 222b that fixes the lower wall portion 222a to the lower case 42a side at the lower end side. The holding member 220 is screwed to the lower case 42a with the lower holding member 222 at the fixing portion 222b, so that the lower wall portion 222a is erected so as to extend in the front-rear direction (the direction from the front side to the back side) of the suction tool main body 42. Note that the fixing portion 222b is not an essential configuration, and any configuration that can structurally position the lower holding member 222 with respect to the lower case 42a may be used.

[0041] Here, with reference to FIG. 11, the cleaning body driving unit 48 will be specifically described. At the axial center position of the driven pulley 216, a shaft insertion hole 216a that opens in a substantially oval shape is provided. The shaft portion 202k of the second attachment body 202y is a shaft body having a substantially oval external shape similar to the shaft insertion hole 216a. Further, on the lower wall portion 222a of the holding member 220, a shaft support portion 220c for rotatably supporting (supporting) the second attachment body 202y is provided. In the shaft support portion 220c, a bearing 225 for rotatably supporting by inserting the shaft portion 202k is provided. Further, the shaft portion 202k is rotatably supported by a bearing member 202z on the tip end side. Therefore, the second attachment body 202y is fixed to the driven pulley 216 in a state where the shaft portion 202k is 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. Since it is configured in this way, by connecting the first attachment body 202x provided on the rotating cleaning body 46 side to the second attachment body 202y, the rotating cleaning body 46 can rotate in conjunction with the driven pulley 216. For this reason, it can also be expressed that the second attachment body 202y is a part of the driven pulley 216.

[0042] At a position on the front side of the suction tool main body portion 42 in the lower wall portion 222a, a shaft support portion 220c for rotatably supporting (supporting) the second attachment body 202y provided at the end of the rotating cleaning body 46 is provided. Further, at a position on the back side of the suction tool main body portion 42 in the lower wall portion 222a, a receiving portion 222d that is cut out so as to be able to support the drive motor 210 is provided. Specifically, the drive motor 210 has a drive motor main body 210a that forms a motor and an output shaft, and includes a drive motor main body 210a1 that forms most of the motor and a bulging portion 210a2 that has a smaller diameter than the drive motor main body 210a1 and bulges in the axial direction. The output shaft is provided in the bulging portion 210a2.

[0043] The receiving portion 222d is formed to extend downward from the upper end of the lower wall portion 222a. Therefore, when incorporating the drive unit 210, it can be easily assembled by sliding the bulging portion 210a2 along the receiving portion 222d. Such incorporation can be more easily performed if it is carried out with the power transmission body 212 spanned between the output-side pulley 214 and the driven-side pulley 216, as there is no problem of being difficult to span due to the tension of the power transmission body 212. Further, since the holding member 220, the drive unit 210, the power transmission body 212, the output-side pulley 214, the second attachment 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, it is easy to incorporate them into the lower case 42a of the cleaning body drive unit 48. Further, a screw hole 222e is provided at a position adjacent to the receiving portion 222d for screwing the end of the drive unit main body 210a1.

[0044] Also, as shown in FIG. 5, the upper holding member 224 is a plate-shaped portion erected with respect to the upper case 42b, which constitutes the upper side of the suction tool main body 42. The upper holding member 224 is provided corresponding to the portion where the receiving portion 222d is provided in the above-described lower holding member 222. Therefore, when the upper case 42b and the lower case 42a together constitute the suction tool main body 42, the open portion above the receiving portion 222d is closed by the upper holding member 224. Thereby, it is possible to prevent the drive unit 210 from unexpectedly dropping out of the receiving portion 222d.

[0045] 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.

[0046] 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 when 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 portion 50b is in communication with a communication portion 45 that connects the joint portion 44 and the second dust collecting portion 50, which will be described in detail later, and is connected to an end portion of the communication portion 45.

[0047] In addition to providing openings in the intake section 50a and the discharge section 50b as shown in the illustrated example, it is preferable that a closing member such as a shutter or a valve is provided in either or both of the intake section 50a and the discharge section 50b for the second dust collection section 50. Further, when providing the closing member, it is preferable that the closing member is in an open state when the second dust collection section 50 is attached to the second dust collection section placement section 64, and the closing member is in a closed state when the second dust collection section 50 is removed from the second dust collection section placement section 64. The closing member can be electrically opened and closed, but it is preferable that it is mechanically opened and closed along with the attachment and detachment operation of the second dust collection section 50 with respect to the second dust collection section placement section 64.

[0048] For example, the closing member is a plate-shaped shutter capable of closing the openings forming the intake section 50a and the discharge section 50b, and while the shutter is biased in the direction of closing the opening by a biasing member such as a spring, a contact member that contacts the shutter and pushes it in the opening direction is provided when the second dust collection section 50 is inserted into the second dust collection section placement section 64. It is preferable to adopt a configuration such as this. By adopting such a configuration, in a state where the second dust collection section 50 is inserted into the second dust collection section placement section 64, the opening is opened, and in a state where the second dust collection section 50 is removed from the second dust collection section placement section 64, a shutter that operates so as to close the opening can be provided in the intake section 50a or the discharge section 50b. Thereby, the second dust collection section 50 can be configured such that when the second dust collection section 50 is set in the second dust collection section placement section 64, the openings forming the intake section 50a and the discharge section 50b automatically open, and when the second dust collection section 50 is removed from the second dust collection section placement section 64, they automatically close.

[0049] The dust removing part 54 is for removing the dust adhering to the rotary cleaning body 46. As shown in FIGS. 4 and 8, the dust removing part 54 is provided at the boundary part between the rotary cleaning body arrangement part 60 where the rotary cleaning body 46 rotates and the second dust collecting part 50. The dust removing part 54 extends toward the rotary cleaning body 46. The dust removing part 54 is provided at a position where it abuts against the cleaning body main body 200 of the rotary cleaning body 46. Also, the dust removing part 54 is detachably attached to the suction tool main body part 42 as appropriate. In the present embodiment, the dust removing part 54 is integrally provided with respect to the second dust collecting part 50 described above. Therefore, the dust removing part 54, together with the second dust collecting part 50, is detachably attached to the suction tool main body part 42 as appropriate.

[0050] The dust removing part 54 can be, for example, in the shape of a blade or the like, but in the present embodiment, it is in the shape of comb teeth. The dust removing part 54 can efficiently scrape off the dust from the surface of the rotary cleaning body 46 and is provided in a posture suitable for scraping off the dust toward the second dust collecting part 50 side.

[0051] Specifically, the dust removing part 54 has a protrusion group 54g composed of a plurality of protrusions 54a. The protrusions 54a protrude toward the rotary cleaning body 46 in a state where they are installed with respect to the suction tool main body part 42. The protrusion group 54g is provided such that, in a state where it is installed with respect to the suction tool main body part 42, the plurality of protrusions 54a are arranged along the axial direction of the rotary cleaning body 46. Also, the protrusion group 54g is provided such that a plurality of them are arranged along the rotation direction of the rotary cleaning body 46. Further, the protrusion group 54g is arranged at a position downstream in the rotation direction of the rotary cleaning body 46 with respect to the opening of the intake part 50a which is the entrance to the second dust collecting part 50 and at a position behind the rotary cleaning body 46. Here, an example in which two sets of protrusion groups 54g are provided in the rotation direction of the rotary cleaning body 46 is shown, but a configuration in which the protrusion amount of one protrusion group 54g is larger than the protrusion amount of the other protrusion group 54g may also be used.

[0052] More specifically, the protrusion 54a forming the protrusion group 54g is provided at a position above the opening forming the intake part 50a in the second dust collection part 50. Further, the protrusions 54a are arranged at predetermined intervals across substantially the entire opening width of the intake part 50a, and are also arranged at predetermined intervals in multiple rows in the vertical direction. As a result, the protrusions 54a forming the protrusion group 54g are arranged along the axial direction of the rotary cleaning body 46 and along the rotation direction of the rotary cleaning body 46 at a position on the downstream side in the rotation direction of the rotary cleaning body 46 and behind the rotary cleaning body 46.

[0053] Also, as shown in FIGS. 4 and 9, a scraper 56 is provided on the bottom surface side of the suction tool main body 42. The scraper 56 is provided so as to extend in the axial direction of the rotary cleaning body 46 at the boundary portion of the suction port 62. The scraper 56 forms a gap with the rotary cleaning body 46 and is provided such that its tip protrudes toward the cleaning surface. Thereby, the scraper 56 can scoop up the dust on the cleaning surface and collect the dust in the second dust collection part 50. Further, it is preferable that the upper surface of the scraper 56 has an inclined shape that gets closer to the cleaning surface toward the tip so as to facilitate the transfer of dust.

[0054] The energization part 52 is a terminal electrically connected to the cleaning body drive part 48 via wiring arranged in the housing part 66. The terminal forming the energization part 52 is electrically connected to the terminal provided on the cleaner main body 20 side by connecting the joint part 44 to the pipe connection part 22b of the cleaner main body 20. Thereby, power can be supplied from the cleaner main body 20 side to the cleaning body drive part 48 to rotate the rotary cleaning body 46.

[0055] ≪Regarding the extension pipe 90≫ The extension pipe 90 is a cylindrical member connected to the pipe connection part 22b of the cleaner main body 20 and the joint part 44 of the suction tool 40 described above. As shown in FIG. 13, the extension pipe 90 has an engaged part 310 that engages with a support column part 350 provided on a support device 300 to be described in detail later.

[0056] As shown in FIG. 13, the engaged portion 310 is a portion that engages with the engaging portion 352 provided in the support device 300, which will be described in detail later. The engaged portion 310 may be provided integrally with the pipe forming the extension pipe 90, but in this modified example, it is configured such that 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) attached to the pipe forming the extension pipe 90. The receiving portion 312 is a hollow portion formed to bulge radially outward on the outer peripheral surface of the extension pipe 90.

[0057] The receiving portion 312 includes a first opening 314 that opens toward the suction tool 40 side. Further, the receiving portion 312 has a second opening 316 formed to open on the back side. Specifically, the second opening 316 is formed to open on the surface (contact surface 318) on the side facing the support column portion 350 provided in the support device 300 in a state where it is installed in the support device 300, which will be described in detail later. Also, the receiving portion 312 has a first energizing portion, which will be described later, for receiving power supply.

[0058] ≪Regarding the support device 300≫ As shown in FIG. 1, the support device 300 supports the state in which the extension pipe 90 and the suction tool 40 are attached to the cleaner main body 20, and may have a charging function. As shown in FIG. 14, the support device 300 has a placement portion 340, a support column portion 350, and a receiving portion 370.

[0059] The placement portion 340 is a portion that serves as a pedestal for placing the suction tool 40. The placement portion 340 has a stopper 342 on the front side. The stopper 342 is formed to protrude upward from the top surface side of the placement portion 340. Also, the stopper 342 is formed to extend in the width direction of the placement portion 340. Therefore, the stopper 342 can position the suction tool 40 disposed on the top surface of the placement portion 340 so that it does not move beyond the stopper 342 to the front side.

[0060] The support portion 350 is a columnar portion erected vertically on the back side of the placement portion 340 (the side opposite to the stopper 342). The support portion 350 is a portion that engages with and supports an extension pipe 90 connected to a suction tool 40 disposed on the placement portion 340. Specifically, the support portion 350 can support the extension pipe 90 by engaging the engaged portion 310 of the extension pipe 90 with an engaging portion 352 provided on the upper end side. Further, the support portion 350 has a second energizing portion that can be electrically connected to a first energizing portion provided on the suction tool 40 side of the extension pipe 90. Thereby, it is possible to charge the battery 34 via the extension pipe 90. To enable such a configuration, the extension pipe 90 is provided with wiring for connecting a third energizing portion (a third energizing portion electrically connected to the battery 34) on the cleaner body 20 side and the first energizing portion. And, in order to supply power to the suction tool 40, energizing portions (fourth and fifth energizing portions) are provided on each of the cleaner body 20 side and the suction tool 40 side of the extension pipe 90, and wiring for connecting the fourth energizing portion (a fourth energizing portion electrically connected to the battery 34) and the fifth energizing portion is arranged in the extension pipe 90.

[0061] As shown in FIG. 15, the engaging portion 352 has four protruding portions including a first protruding portion 354, a second protruding portion 356, a third protruding portion 358, and a fourth protruding portion 359. The first protruding portion 354 is a protruding portion provided so as to protrude from the lower side toward the upper side on the front side of the support portion 350. The first protruding portion 354 is a portion that is inserted into the receiving portion 312 through the first opening 314 provided in the extension pipe 90 described above. The second protruding portion 356 is inside a space 360 that is open toward the front side and the top surface side on the upper end side of the support portion 350, and is provided so as to face the first protruding portion 354 with a predetermined interval therebetween. The third protruding portion 358 is a protruding portion arranged so as to intersect the first protruding portion 354. The third protruding portion 358 is arranged inside the space 360 in the same manner as the second protruding portion 356. Further, although the first protruding portion 354 and the third protruding portion 358 may be separated from each other, in the present embodiment, the third protruding portion 358 is connected to the first protruding portion 354 at the middle portion in the width direction of the first protruding portion 354. Therefore, the first protruding portion 354 and the third protruding portion 358 are formed in a substantially "T" shape in plan view. Further, the fourth protruding portion 359 is provided so as to protrude toward the space 360 on the surface of the first protruding portion 354 facing the space 360 side. The fourth protruding portion 359 is provided at a position facing the second protruding portion 356.

[0062] The space 360 is the portion where the second protrusion 356 and the third protrusion 358 are arranged. At the edge on the upper end side of the space 360, a chamfered portion 360a having a shape such as a tapered shape is provided in order to easily guide the receiving portion 312 provided in the extension pipe 90. Further, the space 360 has an opening width on the front side that is equal to or greater than the width of the receiving portion 312 provided in the extension pipe 90. Further, the above-described first protrusion 354 is formed so as to rise upward from below at a position slightly protruding forward from the opening portion on the front side of the space 360. Further, the width of the above-described third protrusion 358 is equal to or less than the width of the second opening 316 formed in the contact surface 318 of the receiving portion 312 in the extension pipe 90. Further, the second protrusion 356 is provided on both sides in the width direction with respect to the third protrusion 358. Therefore, by inserting the receiving portion 312 in the extension pipe 90 toward the space 360, the contact 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 contact surface 318. Thereby, the engaged portion 310 provided on the extension pipe 90 side and the engaging portion 352 provided on the support portion 350 side are in an engaged state.

[0063] In addition, in the above-described modification, as the engaging portion 352, an example in which four protrusions including the first protrusion 354, the second protrusion 356, the third protrusion 358, and the fourth protrusion 359 are provided is shown, but the present invention is not limited to this. For example, only the first protrusion 354 is provided, or among the other protrusions (the second protrusion 356, the third protrusion 358, and the fourth protrusion 359) excluding the first protrusion 354, one or more of the protrusions may not be provided.

[0064] As shown in FIG. 14, the receiving part 370 supports the vacuum cleaner 10 in an upright state by receiving the first dust collecting part 24 of the vacuum cleaner 10. The receiving part 370 is provided on the upper end side of a receiving part support column 372 which is erected on the rear side with respect to the column 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 side part of the first dust collecting part 24 fits therein. Further, a recess 370b for the extension pipe is provided on the peripheral part of the receiving part 370. The recess 370b for the extension pipe is formed in a concave shape so as to fit or abut against a part of the peripheral part of an extension pipe 90 that connects the cleaner main body 20 and the suction tool 40 in the vacuum cleaner 10.

[0065] As shown in FIG. 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 column 372 is in a state aligned with the extension pipe 90 fitted into the recess 370b for the extension pipe. Therefore, by placing the suction tool 40 connected to the tip side of the extension pipe 90 on the placement part 340 and making the first dust collecting part 24 fit into the receiving part 370, the vacuum cleaner 10 is in a state of being stably supported by the extension pipe 90 and the receiving part support column 372 arranged side by side. Note that, instead of the recess 370b for the extension pipe, a recess for the pipe connection part that fits or abuts against a part of the peripheral part of the pipe connection part 22b may be used.

[0066] A support side terminal 370c is provided on the receiving part 370. The support side terminal 370c is provided so as to correspond to a main body side terminal 25 provided on the vacuum cleaner 10. The support side terminal 370c is in a state of being in electrical contact and connected to the main body side terminal 25 provided at a position adjacent to the first dust collecting part 24 in the cleaner main body 20 by fitting the first dust collecting part 24 of the vacuum cleaner 10 into the first dust collecting part recess 370a of the receiving part 370. Specifically, the main body side terminal 25 is arranged between the suction port of the pipe connection part 22b and the connection port of the pipe connection part 22b with the first dust collecting part 24. Preferably, the main body side terminal 25 is provided on the surface of the support device 300 that faces the bottom surface of the receiving part 370. The main body side terminal 25 may be electrically connected to the control device 32 so that the control device 32 can detect energization. Although a configuration in which the main body side terminal 25 is provided on the extension pipe 90 can be considered, there is a problem that it is difficult to perform further wiring because the extension pipe 90 has the above-described charging wiring. By providing the main body side terminal 25 on the cleaner main body 20, it is possible to avoid the complexity of further wiring the extension pipe 25.

[0067] ≪Operation of the Electric Vacuum Cleaner 10≫ The electric vacuum cleaner 10 is operable in a plurality of operation modes including a first mode, a second mode, and a third mode. In the present embodiment, the electric vacuum cleaner 10 functions as a mode selection reception unit that receives the selection of the operation mode by the operation unit 28, and is capable of selecting an intentionally or automatically selected operation mode by performing a switching operation via the operation unit 28. The electric vacuum cleaner 10 can execute an operation according to the selected operation mode under the control of the control device 32 (processing execution unit).

[0068] The first mode is an operation mode in which the cleaning body drive unit 48 is driven while the drive of the electric blower 22 is stopped. In the first mode, since the electric blower 22 is in a stopped state, the suction force by the electric blower 22 is not generated. On the other hand, in the first mode, since the cleaning body drive unit 48 is driven, the rotary cleaning body 46 rotates to scrape off the dust on the cleaning surface. In the first mode, the dust is collected in the second dust collecting unit 50 by the rotation of the rotary cleaning body 46. In the first mode, since the suction force by the electric blower 22 does not act, the dust collected in the second dust collecting unit 50 remains in the second dust collecting unit 50.

[0069] The second mode is an operation mode for driving the electric blower 22. In the second mode, the electric blower 22 is put into a driving state, and a suction force is generated. Also, before the operation in the second mode, if dust has accumulated in the second dust collecting part 50 collected by the operation in the first mode, by starting the operation in the second mode, the dust accumulated in the second dust collecting part 50 can be recovered to the first dust collecting part 24 by the suction force of the electric blower 22. Further, in the second mode, the cleaning body driving part 48 may be driven together with the electric blower 22. Thereby, since the rotary cleaning body 46 rotates by the driving of the cleaning body driving part 48, the dust collected by the rotary cleaning body 46 passes through the second dust collecting part 50 and is collected into the first dust collecting part 24 by the suction force. For example, the user can perform cleaning in the first mode at a timing when they do not want to generate noise (at night or while the child is sleeping), and perform cleaning in the second mode at other timings, so that cleaning according to the situation becomes possible.

[0070] The third mode is an operation mode for sucking dust from the second dust collecting part 50 toward the first dust collecting part 24 by driving the electric blower 22 over a predetermined time. The third mode can be performed by the user intentionally switching the operation via the operation part 28. Instead of this, or in addition to this, in the present embodiment, it is assumed that the operation in the third mode is automatically performed on the condition that the vacuum cleaner 10 starts to be supported (installed) on the support device 300. The operation conditions of the operation in the third mode may be, as in a modification example described separately later, in addition to the vacuum cleaner 10 being supported (installed) on the support device 300, other conditions may be added, but in the present embodiment, when the vacuum cleaner 10 is supported (installed) on the support device 300, the operation in the third mode is automatically performed.

[0071] Detection of the support (installation) of the vacuum cleaner 10 on the support device 300 can be realized by an appropriate method, such as providing a sensor. In the present embodiment, when the main body side terminal 25 and the support side terminal 370c are electrically connected by fitting the first dust collection part 24 into the recess 370a for the first dust collection part of the receiving part 370 in the receiving part 370, it is assumed that the vacuum cleaner 10 is supported (installed) on the support device 300, and the operation in the third mode is automatically performed. That is, in the present 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 (installed) on the support device 300, and the operation in the third mode is automatically performed on the condition that the detection that the vacuum cleaner 10 is supported (installed) on the support device 300 is performed.

[0072] ≪Modification Example≫ The above-described vacuum cleaner 10 is merely an example of the present invention, and may have a configuration as shown below, for example.

[0073] The above-described vacuum cleaner 10 can perform a mode switching operation by the operation unit 28, but the present invention is not limited thereto, and instead of the operation unit 28 or in addition to the operation unit 28, it can be provided with a voice recognition unit that accepts operations by voice recognition. In such a configuration, it is preferable to switch to the recognized mode on the condition that the voice recognition unit recognizes a voice indicating any of a plurality of modes. When configured in this way, not only a vacuum cleaner of the type that the user holds by hand and uses as described above, but also a vacuum cleaner of the type that operates without the user touching it, such as a so-called robot vacuum cleaner, can easily switch modes.

[0074] The above-described vacuum cleaner 10 has been exemplified as having a configuration in which the electric blower 22 is stopped in the first mode and the electric blower 22 is driven in the second mode. However, the present invention is not limited to this. For example, instead of or in addition to the first mode and the second mode, 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 greater 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 vacuum cleaner 10 not only performs control to turn on and off the electric blower 22, such as switching between the first mode and the second mode, but may also change the suction force by adjusting the output of the electric blower 22, such as in the first drive mode and the second drive mode. With such a configuration, the vacuum cleaner 10 performs cleaning while suppressing the noise associated with the driving of the electric blower 22 in the first drive mode in which the electric blower 22 operates with a first parameter (for example, a low rotation speed), and can perform cleaning in a state where the suction force by the electric blower 22 sufficiently acts in the second drive mode in which the electric blower 22 operates with a second parameter (for example, a high rotation speed). For example, in the first drive mode, if the parameter at which dust reaches the second dust collection unit 50 is set as the first parameter, and in the second drive mode, if the parameter at which dust reaches the first dust collection unit 24 is set as the second parameter and the electric blower 22 is operated, cleaning according to the situation becomes possible.

[0075] The above-described vacuum cleaner 10 is an example of a vacuum cleaner having a stick-like appearance, but the present invention is not limited thereto. For example, a canister-type vacuum cleaner (a vacuum cleaner main body including a main body portion and a first dust collection portion, 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 pipe), or a so-called robot vacuum cleaner, etc. are also possible. Further, when the vacuum cleaner main body 20 and the suction tool 40 are not separate from each other like a self-propelled robot vacuum cleaner, it is not necessary to provide the first dust collection portion 24 in the vacuum cleaner main body 20 and the second dust collection portion 50 in the suction tool 40 as in the case of the vacuum cleaner 10, and a configuration in which the first dust collection portion 24 and the second dust collection portion 50 are arranged in the same housing or the like may be employed. Even in this case, the second dust collection portion 50 is disposed between a communication portion having a discharge portion 50b discharging toward the first dust collection portion 24 side at an end and a rotary cleaning body 46.

[0076] Further, the above-described vacuum cleaner 10 is a vacuum cleaner in a form including an extension pipe 90 connecting the vacuum cleaner main body 20 and the suction tool 40, but the present invention is not limited thereto. It is also possible to use a vacuum cleaner in a form not including the extension pipe 90 connecting the vacuum cleaner main body 20 and the suction tool 40.

[0077] In the above-described vacuum cleaner 10, an example is shown in which the second dust collection portion 50 is formed such that the width is substantially the same at any position from the intake portion 50a side toward the discharge portion 50b side, but the present invention is not limited thereto. For example, as shown in FIG. 11, the second dust collection portion 50 may be formed such that the width along the axial direction of the rotary cleaning body 46 decreases as it goes from the intake portion 50a side toward the discharge portion 50b side. By adopting such a configuration, when the suction force by the electric blower 22 acts, the dust flowing into the second dust collection portion 50 can be smoothly sucked from the intake portion 50a side toward the discharge portion 50b side.

[0078] In the above-described embodiment, an example was shown in which the operation in the third mode is automatically performed by energization due to the contact between the main body side terminal 25 and the support side terminal 370c by supporting the vacuum cleaner 10 on the support device 300. However, it is also possible to adopt a configuration in which it is possible to set whether or not to automatically perform the operation in the third mode when the vacuum cleaner 10 is supported on the support device 300. Specifically, for example, as shown in FIG. 1, a third mode setting unit 380 for setting whether or not the operation in the third mode is possible may be provided in the receiving unit 370, or may be provided in the mounting unit 340 or the like of the support device 300. In such a configuration, it is preferable to perform the operation in the third mode on the condition that the third mode setting unit 380 has set to permit the operation in the third mode and that the vacuum cleaner 10 is supported (installed) on the support device 300, either partially or entirely, as part of the operating conditions. Thereby, when the vacuum cleaner 10 is supported on the support device 300, it becomes possible to set whether or not to automatically perform the operation in the third mode according to the intention of the user, and the convenience is further improved. Note that the third mode setting unit 380 is, for example, a changeover switch between effective (on) and ineffective (off). Also, the third mode setting unit 380 may be provided in the vacuum cleaner 10.

[0079] In the above-described embodiment, an example was shown in which the operation in the third mode was performed on the condition that the vacuum cleaner 10 is supported by the support device 300. However, it is possible to provide further other conditions as the operation conditions for the third mode. For example, in addition to the vacuum cleaner 10 being supported by the support device 300, the vacuum cleaner 10 may be configured to operate in the third mode on the condition that there is an operation history in which the operation in either the first mode or the second mode has been performed after the operation in the third mode performed previously. By adopting such a configuration, it is possible to more reliably prevent the dust collected by the operation in the first mode or the second mode from remaining in the second dust collection unit 50. Note that the operation history may be stored in the control device 32 of the vacuum cleaner 10 or in a recording medium that can be read or communicated with by the control device 32. Further, when the third mode is executed based on the operation history, the control device 32 may reset the operation history.

[0080] Further, the vacuum cleaner 10 may, for example, have a timer setting. That is, the vacuum cleaner 10 may be provided with a time measuring means for measuring time and a time setting means for setting time, and may be configured to perform the third mode when the time measured by the time measuring means becomes the set time by the time setting means when the vacuum cleaner 10 is installed on the support device 300.

[0081] Note that the vacuum cleaner system S may not have any of the settings 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, when the vacuum cleaner 10 is installed on the support device 300, it may be Mode 1 having any one of the settings of the third mode setting unit 380, the operation history, and the timer setting, or may be Mode 2 having the setting of the third mode setting unit 380 and at least one of the operation history and the timer setting, or may be Mode 3 having the operation history and the timer setting.

[0082] Aspect 1 is as described above. In Aspect 2, when the setting of the third mode setting unit 380 is in an enabled state, the third mode may be executed in a state with an operation history, or when the setting of the third mode setting unit 380 is in an enabled state, the third mode may be executed when the time of the timer setting is reached. Furthermore, when the setting of the third mode setting unit 380 is in an enabled state, the third mode may be executed when the time of the timer setting is reached in a state with an operation history.

[0083] In Aspect 3, when the vacuum cleaner 10 is installed on the support device 300, the third mode may be executed when the time of the timer setting is reached in a state with an operation history. On the other hand, when the vacuum cleaner 10 is not installed on the support device 300, the third mode may be performed according to the timer setting, or the operation history and the timer setting. That is, the third mode may be executed when the time of the timer setting is reached in a state with an operation history, or the third mode may be executed when the time of the timer setting is reached regardless of the presence or absence of an operation history.

[0084] Also, in the above embodiment, the vacuum cleaner 10 is configured to execute the third mode in which the electric blower 22 is driven for a predetermined time. However, a dust detection means for detecting dust passing through the air passage communicating with the first dust collection unit 24 may be provided in the vacuum cleaner 10, and the third mode in which the electric blower 22 is driven may be executed in a state where the dust detection means detects dust.

[0085] Also, the vacuum cleaner 10 of the above embodiment may execute the third mode before or after charging by the support device 300, or the power supplied to the electric blower 22 during the execution of the third mode may be used from both the battery 34 and the support device 300 (commercial power supply).

[0086] As described above, the vacuum cleaner of the present invention is an invention that solves the problems in the technology disclosed in the above Patent Document 1 (Japanese Utility Model Publication No. 53-134769). That is, in the above Patent Document 1, a vacuum cleaner is provided 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 collecting box provided with a dust inlet on a surface facing the rotating brush, and an opening is provided on the lower surface of the rotating brush. When the vacuum cleaner disclosed in Patent Document 1 includes a dust collecting box in the main body together with the rotating brush and the electric motor and does not include an electric blower, since no noise is generated by the driving of the electric blower, it is possible to suppress the noise during cleaning. However, when configured not to include an electric blower that is a source of suction force, as in the vacuum cleaner of Patent Document 1 above, there is a problem that it is difficult to take in dust adhering to, for example, a plush carpet or a carpet into the main body. Therefore, an object of the present invention is to realize a vacuum cleaner capable of selectively using cleaning by suction force of an electric blower and cleaning by rotation of a rotating brush.

[0087] The vacuum cleaner 10 according to the above-described embodiment and modification embodies the inventions according to the following (1-1) to (1-14). According to the inventions according to the following (1-1) to (1-14), for example, the following effects can be obtained.

[0088] (1-1) The vacuum cleaner of the present invention includes an electric blower that generates a suction force, a dust collecting unit where dust is collected, a suction port for sucking in dust, and a rotating cleaning body that rotates by driving of a driving unit. The dust collecting unit has a first dust collecting unit and a second dust collecting unit arranged closer to the suction port side than the first dust collecting unit in a path connecting the first dust collecting unit and the suction port, and is switchable to any one of a plurality of operation modes including a first mode in which the driving unit is driven with the driving of the electric blower stopped and a second mode in which the electric blower is driven.

[0089] By operating the vacuum cleaner of the present invention in the first mode, the cleaning body driving unit is driven with the drive of the electric blower stopped, so that the rotating cleaning body can be rotated and cleaned without generating the driving noise of the electric blower. Further, the vacuum cleaner of the present invention is provided with a dust collecting unit including, in addition to the first dust collecting unit, a second dust collecting unit arranged on the suction port side with respect to the first dust collecting unit. Therefore, when the vacuum cleaner of the present invention operates in the first mode in which the suction force by the electric blower is not generated, the dust collected by the rotation of the rotating cleaning body can be collected in the second dust collecting unit.

[0090] On the other hand, by operating in the second mode, the vacuum cleaner of the present invention can drive the electric blower to perform cleaning using the suction force by the electric blower. Further, the vacuum cleaner of the present invention is provided with the first dust collecting unit at a position away in the direction away from the suction port (suction direction) with respect to the second dust collecting unit. Therefore, the vacuum cleaner of the present invention can collect the dust collected in the second dust collecting unit by the operation in the first mode in the first dust collecting unit by the suction force by the electric blower.

[0091] As described above, the vacuum cleaner of the present invention is provided with the dust collecting unit including the first dust collecting unit and the second dust collecting unit, and is operable in a plurality of modes including the first mode and the second mode. Thereby, the vacuum cleaner of the present invention can properly use cleaning using the suction force by the electric blower and cleaning by the rotation of the rotating brush.

[0092] (1-2) The vacuum cleaner of the present invention can be installed on a support device provided separately from the vacuum cleaner, and is characterized by operating in a third mode of driving the electric blower to suck dust toward the first dust collecting unit on the condition that it is installed on the support device.

[0093] The electric vacuum cleaner of the present invention is driven by an electric blower on the condition that it is installed on a support device. Therefore, by operating in the third mode, the electric vacuum cleaner of the present invention can keep the second dust collection part clean. In other words, it is possible to suppress excessive accumulation of dust in the second dust collection part.

[0094] (1-3) The electric vacuum cleaner of the present invention can be installed on a support device provided separately from the electric vacuum cleaner. When installed on the support device and satisfying one or more other conditions, it is characterized in that it operates in a third mode in which the electric blower is driven to suck dust toward the first dust collection part.

[0095] By configuring the electric vacuum cleaner of the present invention as described in (1-3) above, the second dust collection part can be kept clean. In other words, it is possible to suppress excessive accumulation of dust in the second dust collection part.

[0096] (1-4) As in the above-described modification, the electric vacuum cleaner of the present invention is provided with a third mode setting unit for setting whether or not to operate in the third mode in the support device or the electric vacuum cleaner. As the other condition, a setting for permitting operation in the third mode is made in the third mode setting unit, and it is characterized in that it operates in the third mode.

[0097] By configuring the electric vacuum cleaner of the present invention as described in (1-4) above, when the electric vacuum cleaner 10 is installed on the support device 300, it is possible to set whether to automatically operate in the third mode according to the user's intention, further improving convenience.

[0098] (1-5) As in the above-described modification, the electric vacuum cleaner of the present invention has an operation history in which operation in any one of the first mode and the second mode is performed after the operation in the third mode performed previously as the other condition, and it is characterized in that it operates in the third mode.

[0099] By adopting the configuration as described in (1-5) above, the vacuum cleaner of the present invention can more reliably prevent the dust collected by operating in the first mode or the second mode from remaining in the second dust collection unit 50.

[0100] (1-6) It is preferable that the vacuum cleaner of the present invention is characterized by including a detection unit that detects that the vacuum cleaner is installed on the support device.

[0101] By adopting the configuration as described in (1-6) above, the vacuum cleaner of the present invention can detect that it is installed on the support device. In the above embodiment, an example is shown in which 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. However, the present invention is not limited to this. For example, various sensors, switches, etc. may be used as the detection unit.

[0102] (1-7) It is preferable that the vacuum cleaner of the present invention is characterized by including a cleaner main body having the electric blower and the first dust collection unit, and a suction tool having the suction port, the second dust collection unit, the drive unit, and the rotary cleaning body.

[0103] By adopting the configuration as described in (1-7) above, when the vacuum cleaner of the present invention operates in the first mode, it is possible to rotate and clean the rotary cleaning body without generating the driving sound of the electric blower, and collect dust in the second dust collection unit of the suction tool. Also, by adopting the configuration as described in (1-7) above, when the vacuum cleaner of the present invention operates in the second mode, it can perform cleaning using the suction force of the electric blower, and can perform an operation of collecting the dust collected in the second dust collection unit in the first dust collection unit by the operation in the first mode.

[0104] (1-8) The electric vacuum cleaner of the present invention is provided on the cleaner main body, and includes a detection unit that detects that the electric vacuum cleaner is installed on the support device by electrical connection with the support device, and an extension pipe that connects the cleaner main body and the suction tool. It is characterized in that it can be charged by supplying power from the support device through a power supply unit provided on the extension pipe to a battery provided on the cleaner main body. By adopting the configuration as described in (1-8) above, the electric vacuum cleaner of the present invention can detect the installation on the support device. Further, by adopting the configuration as described in (1-8) above, the electric vacuum cleaner of the present invention can supply power from the support device through the power supply unit provided on the extension pipe to charge the battery provided on the cleaner main body. Furthermore, as described in (1-8) above, by providing the detection unit on the cleaner main body, it is not necessary to provide wiring or the like connected to the detection unit on the extension pipe.

[0105] (1-9) In the electric vacuum cleaner of the present invention, the support device includes a receiving part that supports the first dust collection part and a detection unit that detects that the electric vacuum cleaner is installed. The detection unit is provided on the receiving part and detects the installation of the electric vacuum cleaner in a state where the first dust collection part is supported by the receiving part.

[0106] By adopting the configuration as described in (1-9) above, in the electric vacuum cleaner of the present invention, since the first dust collection part is installed on the receiving part, the stability of the support for the support device is improved, and the detection accuracy can be improved.

[0107] (1-10) The electric vacuum cleaner of the present invention is installable on a support device provided separately from the electric vacuum cleaner, and includes an instruction receiving unit that receives an instruction for operating in a third mode in which the electric blower is driven by contact with the support device to suck dust toward the first dust collection part. For example, the instruction receiving unit is a switch for executing the third mode, and the third mode may be executed by contact or pressing of a part (for example, a protrusion) of the support device against the switch.

[0108] As described in (1-10) above, the vacuum cleaner of the present invention can also be configured to include an instruction receiving unit instead of the detection unit including a sensor or the like, and perform an operation of operating in the third mode and cleaning the second dust collection unit on the condition that the vacuum cleaner is installed on the support device.

[0109] (1-11) The vacuum cleaner of the present invention is provided with a timekeeping means for timing the time and a time setting means for setting the time. As another condition, when the time by the timekeeping means becomes the time by the time setting means, it is preferable that the vacuum cleaner is characterized by performing the third mode.

[0110] As described in (1-11) above, the vacuum cleaner of the present invention can execute the third mode at a timing desired by the user. In addition, the timekeeping means and the time setting means may be applied to the configuration of (1-1) above so that the third mode in which the time by the timekeeping means becomes the time by the time setting means is performed.

[0111] (1-12) In the vacuum cleaner of the present invention, 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 in a state where dust detection means for detecting that dust passes in an air passage communicating with the first dust collection unit detects dust. It is preferable that it is characterized by being.

[0112] As described in (1-12) above, the vacuum cleaner of the present invention can improve quietness by giving a limit to the driving time of the electric blower.

[0113] (1-13) The vacuum cleaner of the present invention has a mode selection reception unit (operation unit 28) that receives the selection of the operation mode, and a processing execution unit (control device 32) that, when receiving the selection of the operation mode in the mode selection reception unit, executes the operation related to the received operation mode. As the operation mode that can be received for selection in the mode selection reception unit, a third mode in which the electric blower is driven to suck dust toward the first dust collection unit is included, which is preferably the case.

[0114] By configuring the vacuum cleaner of the present invention as in the above (1-13), when the third mode is intentionally selected as the operation mode in the mode selection reception unit, the processing execution unit can execute the operation in the third mode. Therefore, by configuring the vacuum cleaner of the present invention as in the above (1-13), the operation in the third mode can be performed according to the user's intention, and the second dust collection unit can be kept clean.

[0115] (1-14) The vacuum cleaner of the present invention is installable on a support device having a charging mechanism provided separately from the vacuum cleaner, and is characterized by performing a third mode in which the electric blower is driven by power supply from a battery and the support device (commercial power supply), which is preferably the case.

[0116] By configuring the vacuum cleaner of the present invention as in the above (1-14), it becomes possible to drive the electric blower by power supply from the support device even when the remaining charge of the battery is low. In addition, when the remaining amount of the battery is below the threshold value, power supply from the support device may be performed, and when the remaining amount of the battery is greater than the threshold value, power supply from the support device may not be performed.

[0117] Here, the vacuum cleaner disclosed in Patent Document 1 (Japanese Utility Model Publication No. 53-134769) includes a dust collection box in the main body together with a rotating brush and an electric motor. Since it does not have an electric blower, no noise is generated during driving, and it is possible to suppress the noise during cleaning. In this prior art, although a configuration in which a dust removing body is provided is adopted, there is a problem that maintenance is difficult.

[0118] Therefore, an object of the present invention is to realize a vacuum cleaner with improved maintainability of the dust removing unit.

[0119] In order to achieve such an object, the vacuum cleaner 10 according to the above-described embodiments and modified examples embodies the inventions according to the following (2-1) to (2-6). According to the inventions according to the following (2-1) to (2-6), for example, the following effects can be obtained.

[0120] (2-1) The vacuum cleaner of the present invention includes a dust collection unit (corresponding to the second dust collection unit 50 in the above embodiment) where dust is collected, a suction port for sucking in dust, and a main body unit (corresponding to the suction tool main body unit 42 in the above embodiment) including a rotating cleaning body that rotates by driving of a driving unit, and a dust removing unit that removes dust adhering to the rotating cleaning body, and the dust removing unit is detachably provided with respect to the main body unit. In this case, the main body unit of the vacuum cleaner may include a configuration communicating with an electric blower or a configuration not connected to a vacuum cleaner main body having an electric blower.

[0121] In the vacuum cleaner of the present invention, as in the above (2-1), since the dust removing unit is detachable from the main body unit, it is easy to perform maintenance on the dust removing unit.

[0122] (2-2) The vacuum cleaner of the present invention is preferably characterized in that the main body unit includes an opening that opens the dust collection unit detachably with respect to the main body unit, a cover unit that opens and closes the opening, and a biasing member that biases the cover unit in a direction to open the opening.

[0123] By adopting the configuration as described in (2-2) above, the vacuum cleaner of the present invention can easily perform the operation of opening and closing the cover and attaching and detaching the dust collection unit.

[0124] (2-3) The vacuum cleaner of the present invention is preferably characterized in that the dust removing unit has a plurality of protrusions protruding toward the rotary cleaning body and arranged in a group of protrusions along the axial direction of the rotary cleaning body.

[0125] By adopting the configuration as described in (2-3) above, the vacuum cleaner of the present invention can clean the rotary cleaning body at each part in the axial direction by the protrusions forming the group of protrusions.

[0126] (2-4) The vacuum cleaner of the present invention is preferably characterized in that a plurality of the protrusions forming the group of protrusions are arranged along the rotation direction of the rotary cleaning body.

[0127] By adopting the configuration as described in (2-4) above, the vacuum cleaner of the present invention can improve the frequency of contact with the dust attached to the rotary cleaning body during one rotation of the rotary cleaning body by the number of the protrusions arranged in the rotation direction of the rotary cleaning body. Therefore, by adopting the configuration as described in (2-4) above, the vacuum cleaner of the present invention can improve the dust removing ability of the dust removing unit.

[0128] (2-5) The vacuum cleaner of the present invention is preferably characterized in that the dust collection unit is mounted rearward with respect to the rotary cleaning body, and the dust removing unit is arranged at a position downstream of the rotation direction of the rotary cleaning body at the inlet of the dust collection unit and rearward with respect to the rotary cleaning body.

[0129] By adopting the configuration as described in (2-5) above, the vacuum cleaner of the present invention can remove dust from the rotary cleaning body at the inlet side of the dust collection unit and smoothly collect it in the dust collection unit.

[0130] (2-6) The electric vacuum cleaner of the present invention is preferably characterized in that the main body portion is a suction tool that communicates with a vacuum cleaner main body having an electric blower.

[0131] By configuring the electric vacuum cleaner of the present invention as described in (2-6) above, it is possible to rotate the rotary cleaning body for cleaning without generating the driving sound of the electric blower by driving the driving unit provided in the suction tool while the driving of the electric blower provided in the vacuum cleaner main body is stopped.

[0132] Here, the vacuum cleaner disclosed in Patent Document 1 (Japanese Utility Model Publication No. 53-134769) includes a dust collection box in the main body together with a rotary brush and an electric motor, and since it does not have an electric blower, no sound generated by driving occurs, and it is possible to suppress the noise during cleaning. However, such a conventional vacuum cleaner has a problem that it is difficult to take in dust adhering to, for example, a plush carpet or a carpet into the main body because it does not utilize the suction of the electric blower.

[0133] Therefore, an object of the present invention is to realize a vacuum cleaner capable of performing cleaning while suppressing the generation of noise due to the driving of an electric blower.

[0134] To achieve such an object, the electric vacuum cleaner 10 according to the above-described embodiment and modification employs a configuration as in (3-1). As a result, the electric vacuum cleaner 10 obtains the following effects.

[0135] (3-1) The electric vacuum cleaner of the present invention includes an electric blower (electric blower 22) that generates suction force, a dust collection unit where dust is collected, a suction port for sucking in dust, and a rotary cleaning body that rotates by the driving of a driving unit. The dust collection unit has a first dust collection unit and a second dust collection unit arranged closer to the suction port side than the first dust collection unit in a path connecting the first dust collection unit and the suction port, and is switchable to any one of a plurality of operation modes including a first driving mode for driving the electric blower with a first parameter and a second driving mode for driving the electric blower with a second parameter larger than the first parameter.

[0136] In the electric vacuum cleaner 10 adopting such a configuration, in the first drive mode in which the electric blower operates with the first parameter, cleaning is performed while suppressing the noise associated with the drive of the electric blower. On the other hand, in the second drive mode in which the electric blower operates with the second parameter, cleaning can be performed in a state where the suction force by the electric blower sufficiently acts. Therefore, it is possible to perform cleaning while suppressing the generation of noise due to the drive of the electric blower.

[0137] In addition, it is possible to apply the configurations of the above (1-2) to (1-14) to the configuration of the above (3-1).

[0138] The present invention is not limited to the configurations described in the above embodiments, and can be appropriately modified in design and the like without departing from the scope of the technical idea of the present invention. The constituent elements of the above-described embodiments and modification examples may be arbitrarily selected and combined. Further, any constituent element of each of the above-described embodiments and modification examples may be arbitrarily combined with any constituent element described in the means for solving the invention, the form for implementing the invention, etc., or a constituent element embodying any constituent element described in the means for solving the invention, the form for implementing the invention, etc. It is good to combine and configure arbitrarily. Regarding these, there is also an intention to acquire rights in the present application or a divisional application based on the present application.
