As shown in FIG. 1, the vacuum cleaner unit 1 comprises a vacuum cleaner 3 and a cleaner support device 5. The vacuum cleaner 3 is a so-called stick-type vacuum cleaner provided with a suction tool 310, a cleaner body 340 and a handle tool 390 in this order. The vacuum cleaner 3 is provided with a housing portion 410 for housing the auxiliary dust collector 450 so as to be freely removed from the handle tool 390 side. The housing portion 410 is attached to the cleaner body 340. The vacuum cleaner 3 is a portable type charged from the vacuum cleaner supporting device 5.
Here, the suction tool 310, the vacuum cleaner main body 340, and the handle tool 390 in the vacuum cleaner 3 are arranged in this order in the axial direction (Z), and the suction port 323 of the suction tool 310 (rotation shaft of the rotating brush 319) is The extending direction is taken as the width direction (X), and the direction orthogonal to the axial direction and the width direction (the advancing direction of the rotating brush 319) is taken as the depth direction (Y).

  1-1. Vacuum cleaner body

  The cleaner body 340 comprises a cylindrical housing 341. The cylindrical housing 341 comprises a first cylindrical portion 343, a cylindrical expanded portion 363 and a second cylindrical portion 373. The extension portion 363 is located between the first cylindrical portion 343 and the second cylindrical portion 373 and has a central axis common to the first cylindrical portion 343 and the second cylindrical portion 373. The first cylindrical portion 343 has the same outer diameter as the second cylindrical portion 373. The extension portion 363 has an outer diameter larger than the outer diameter of each of the first cylindrical portion 343 and the second cylindrical portion 373. Thus, the cleaner body 340 has an enlarged portion 363 having a large outer peripheral dimension on the way from the handle tool 390 side to the suction tool 310 side. The extended portion 363 has an end face 369 on the handle tool 390 side continuous with the first cylindrical portion 343 and an end face 371 on the suction tool side continuous with the second cylindrical portion 373 in addition to the outer peripheral surface 365. The end face 369 and the end face 371 are both tapered.

  The shape of the cleaner body 340 is not limited to this, and may have a fixed outer diameter from the handle tool 390 side to the suction tool 310 side, and the outer diameter dimension is small on the way from the handle tool 390 side to the suction tool 310 side It may have a reduced portion. In addition, the shape of the cleaner body 340 is not limited to a cylindrical shape, and for example, a cross-sectional triangle, a cross-section quadrangle, a cross-section hexagon, a cross-section polygonal cylinder such as an octagon cross-section, or a combination thereof or an asymmetric shape It may be cylindrical.

  The vacuum cleaner body 340 includes parts such as an electric blower, a battery, a circuit module, a dust collection pack attachment portion, and an indicator 377, for example. These parts are housed in a cylindrical housing 341. For example, the first cylindrical portion 343 houses a battery, a circuit module and an indicator 377. The extension portion 363 accommodates the electric blower. The second cylindrical portion 373 accommodates the dust collection pack attachment and the dust collection pack. The battery stores power received from the commercial power supply through the circuit module. The battery supplies the stored power to the electric blower through the circuit module. The electric blower generates a negative pressure for suctioning dust. The dust collection pack attachment portion detachably mounts a dust collection pack that accumulates suctioned dust. The circuit module performs charge and discharge control of the battery, drive control of the electric blower, and display control of the indicator 377. The indicator 377 presents various information such as, for example, the battery remaining amount, the operation mode, and the filling rate of the dust collection pack. The first cylindrical portion 343 has an oblong window 351 on its outer circumferential surface 349. The indicator 377 is externally visible through the elongated window 351. The indicator 377 may have an operation function as well as a display function. The operation function is, for example, an ON / OFF button. Thereby, even when the handle tool 390 is removed, the operation of the vacuum cleaner 3 becomes possible.

  The cleaner body 340 has attachment means for removably attaching the handle 390. The engagement portion, which is an example of the attachment means, is not shown in FIG. By operating the attachment button 375 on the handle tool 390 side, the engagement convex portion on the handle tool 390 side is engaged with the engagement recess on the cleaner body 340 side. The attachment means is not limited to this, and may be a screw.

  The vacuum cleaner body 340 has a mounting structure for detachably mounting the housing portion 410. Details of this will be described later.

  1-2. Handle

  The handle 390 comprises a cylindrical housing 391 having a closed upper surface and an open lower surface. The cylindrical housing 391 has a through hole 395 for operating the attachment button 375. The mounting button 375 is exposed to the outside of the cylindrical housing 391 through the through hole 395. When the mounting button 375 is pushed into the interior of the cylindrical housing 391, the engagement between the engagement recess and the engagement projection can be released. Thus, the cylindrical housing 391 and hence the handle 390 can be removed from the cleaner body 340. In addition, the handle tool 390 may be removably attached to the cleaner body 340 by a method other than this. Also, the handle 390 may be attached to the cleaner body 340 in a non-removable manner. For example, the handle 390 may be integrally formed on the cleaner body 340.

  The outer shape of the handle tool 390 is not limited to a cylindrical shape, and for example, a tubular shape having a triangular cross-section, a rectangular cross-section, a hexagonal cross-section, a polygonal cross-section such as an octagonal cross-section, or a combination thereof or an asymmetric tubular May be.

  The cylindrical housing 391 has an outer diameter smaller than the outer diameter of the first cylindrical portion 343 of the cleaner body 340. Therefore, a stepped portion 359 composed of the tapered surface 347 and the upper surface 345 of the first cylindrical portion 343 is formed between the handle 390 and the cleaner body 340.

  The handle 390 includes an operation module 397. The operation module 397 is accessible from the outside through an oval window 393 provided in the cylindrical casing 391. The operation module 397 includes, for example, buttons assigned to start, stop, and suction adjustment of the vacuum cleaner 3, respectively.

  The handle tool 390 includes a holder 399 for holding the auxiliary dust collector 450 contained in the holder 410. Details of this will be described later.

  1-3. Suction tool

  The suction tool 310 has a suction port 323 at its bottom, as shown in FIG. The suction port 323 accommodates the rotating brush 319 therein.

  The suction tool 310 internally has a dust collection pipe that connects the second cylindrical portion 373 of the cleaner body 340 and the suction port 323 of the suction tool 310. The inner wall 315 has a communication port 317 connected to the dust collection pipe. The dust sucked from the suction port 323 is sent to the dust collection pack accommodated in the second cylindrical portion 373 through the communication port 317 and the dust collection pipe.

  The suction device 310 comprises three rollers 321 on the bottom cover 313. Thus, the suction tool 310 can travel smoothly on a surface to be cleaned, such as a floor.

  1-4. Housing

  The housing portion 410 has an opening 433 for housing the auxiliary dust collector 450, as shown in FIG. The auxiliary dust collector 450 is accommodated in the accommodating portion 410 so as to be freely removable from the handle 390 side. More specifically, the housing portion 410 has a bottomed cylindrical shape in which the opening 433 faces the handle tool 390 side. Thereby, the auxiliary dust collector 450 can be easily taken out during use of the vacuum cleaner 3. As mentioned above, the vacuum cleaner 3 incorporates a battery for driving the electric blower. Therefore, the vacuum cleaner 3 has high mobility. Such a highly mobile vacuum cleaner 3 is provided with a housing portion 410 for housing the auxiliary dust collector 450. Therefore, the cleaning with the vacuum cleaner 3 can be performed using the auxiliary dust collector 450 without obstructing the mobility of the auxiliary dust collector 450.

  As shown in FIG. 3, the housing portion 410 includes a first side surface 411, a second side surface 415, a back surface 419, a front surface 425, and a bottom surface 431.

  The first side surface 411 is substantially parallel to the second side surface 415. The first side surface 411 has two vertically elongated projecting pieces 413 on the opposite surface facing the second side surface 415. Here, “longitudinal” means a direction along the cylinder axis of the housing portion 410. The two projecting pieces 413 are respectively disposed at two positions above and below the facing surface. Although not shown in FIG. 3, similarly, the second side surface portion 415 has two vertically elongated projecting pieces 413 on the opposing surface facing the first side surface portion 411. The projecting piece 413 has a vertically-long rectangular shape when the accommodation portion 410 is viewed from the front side. The four projecting pieces 413 are provided at positions near the four corners of the housing portion 410, respectively. Accordingly, the housing portion 410 can be stably fixed to the first cylindrical portion 343. The shape and position of the projecting piece 413 is not limited to this, and an engaging portion is provided on one side and an engaged portion is provided on the other side so that the front surface portion 425 is attached to face the first cylindrical portion 343. It should be done. For example, the projecting piece 413 may project from the front surface 425 in an L shape.

  The front portion 425 has a concave shape that conforms to the outer circumferential surface 349 of the first cylindrical portion 343 of the cleaner body 340. The front face portion 425 has two vertically elongated ridges 427 and one horizontally long engagement projection 429. Here, “lateral” means a direction (circumferential direction) perpendicular to the cylinder axis of the housing portion 410.

  The back surface portion 419 has a parallel portion 421 substantially parallel to the front surface portion 425 and an inclined portion 423 inclined with respect to the front surface portion 425. The inclined portion 423 is for expanding the area of the opening 433. That is, the inclined portion 423 is inclined to the opening side spread. By expanding the area of the opening 433, the head portion 451 of the auxiliary dust collector 450 can be easily inserted into the housing portion 410. Further, when the auxiliary dust collector 450 is taken out from the housing portion 410, the handle portion 457 can be inclined so as to be separated from the handle tool 390. The inclined portion 423 is provided to gradually narrow the internal space of the housing portion 410 from the opening 433 toward the bottom portion 431. Thus, the head portion 451 of the auxiliary dust collection tool 450 can be smoothly moved from the opening 433 to the bottom surface portion 431. The back surface 419 is not limited to this, and may be substantially parallel to the front surface 425 on the entire surface. Further, instead of or in addition to the inclination of the back surface portion 419, the first side surface portion 411 and / or the second side surface portion 415 becomes wider in width from the bottom surface portion 431 toward the opening 433 side. In this case, the width may be gradually broadened from the bottom portion 431 to the middle, and the width may be further widened from the middle to the opening 433 side.

  As shown in FIG. 3, the first cylindrical portion 343 of the cleaner body 340 has four longitudinally extending guide grooves 353 on its outer circumferential surface 349. Here, “longitudinal” means a direction along the cylinder axis of the first cylindrical portion 343. The four guide grooves 353 respectively receive the four projecting pieces 413 of the housing portion 410 and guide the housing portion 410 to an appropriate position.

The first cylindrical portion 343 has four longitudinally extending projecting pieces 355 on its outer peripheral surface 349. The four projecting pieces 355 are disposed on the sides of the four guide grooves 353 and behind the four guiding grooves 353 and are engageable with the four projecting pieces 413 of the housing portion 410, respectively. Specifically, when the projecting piece 355 is engaged with the projecting piece 413, the front surface of the projecting piece 355 abuts on the rear surface of the projecting piece 413. When the housing portion 410 (projecting piece 413) slides along the guide groove 353 to the lower end of the guide groove 353, the four projecting pieces 413 of the housing portion 410 engage with the four projecting pieces 355 of the first cylindrical portion 343 respectively. Do. Thereby, the movement of the first cylindrical portion 343 of the housing portion 410 in the direction other than the cylinder axial direction is restricted.
In the state where the housing portion 410 is attached to the first cylindrical portion 343, the front ends of the first side surface portion 411 and the second side surface portion 415 are close to the outer circumferential surface 349 of the first cylindrical portion 343. Therefore, dust can be prevented from entering between the housing portion 410 and the first cylindrical portion 343. Further, the sense of unity between the housing portion 410 and the first cylindrical portion 343 can be obtained.

  Accordingly, the housing portion 410 is detachably attached to the first cylindrical portion 343 and thus to the cleaner body 340. Therefore, the housing portion 410 can be cleaned by removing the housing portion 410 from the cleaner body 340.

  The first cylindrical portion 343 has one laterally long engaging recess 357 in its outer circumferential surface 349. Here, “lateral” refers to a direction (circumferential direction) perpendicular to the cylinder axis of the first cylindrical portion 343. The engagement recess 357 is engageable with the engagement projection 429 of the housing portion 410. When the housing portion 410 (projecting piece 413) slides along the guide groove 353 to the lower end of the guide groove 353, the engagement convex portion 429 is engaged with (engaged with) the engagement recess 357. Thereby, the movement of the first cylindrical portion 343 of the housing portion 410 in the cylinder axial direction is restricted. However, the engagement between the engagement projection 429 and the engagement recess 357 is designed to be relatively loose. Therefore, the engagement between the engagement convex portion 429 and the engagement concave portion 357 can be released by the intentional and forced slide of the housing portion 410. Thereby, it becomes possible to prevent or reduce unintended detachment from the first cylindrical portion 343 of the housing portion 410 while making it possible to attach and detach the housing portion 410 to the first cylindrical portion 343.

  The front surface portion 425 of the housing portion 410 has the vertically elongated ridge portion 427 as described above. The ridges 427 form a clearance between the front surface 425 of the housing 410 and the outer circumferential surface 349 of the first cylindrical portion 343. The housing portion 410 contacts the first cylindrical portion 343 not at the front surface portion 425 but at the projecting portion 427. Thereby, the contact area to the 1st cylindrical part 343 of the accommodating part 410 can be reduced, As a result, the slide on the 1st cylindrical part 343 of the accommodating part 410 can be made smooth.

  The housing portion 410 is attached to the first cylindrical portion 343 as shown in FIG. The bottom surface portion 431 of the housing portion 410 is along the end surface 369 on the handle tool 390 side of the extension portion 363 of the cleaner body 340. Thereby, a sense of unity between the housing portion 410 and the cleaner main body 340 can be obtained.

As shown in FIG. 4, the dimension in the depth direction (Y) between the back surface 419 of the housing portion 410 and the central axis C of the cleaner body 340 is defined as a dimension L1. A dimension in the depth direction (Y) between the outer circumferential surface 365 of the expanded portion 363 of the cleaner body 340 and the central axis C of the cleaner body 340 is defined as a dimension L2. A dimension in the depth direction (Y) between the rear surface of the wiring cover 367 and the central axis C of the cleaner body 340 is defined as a dimension L3. Dimension L1 is the same as or greater than dimension L2. Also, the dimension L1 is the same as or larger than the dimension L3. That is, a dimension L1 perpendicular to the central axis C of the cleaner body 340 and in the depth direction (Y) away from the attachment portion of the housing 410 on the outer circumferential surface 349 with respect to the central axis C is a dimension L2 of the extended portion 363 Or above. In other words, the housing portion 410 is flush with or protrudes in the depth direction (Y) with respect to the extension portion 363 of the cleaner body 340.
Incidentally, the central axis C of the first cylindrical portion 343 is offset from the central axis C of the expanded portion 363, whereby the receiving portion 410 is flush with or retracted in the depth direction (Y) with respect to the expanded portion 363. It may be
The wiring cover 367 accommodates the wiring connecting the connector 379 (see FIG. 5) and the battery in the first cylindrical portion 343 inside. The wiring cover 367 is exposed to the outside of the extended portion 363 but is not limited thereto. For example, the wiring cover 367 may be housed inside the extension portion 363.

  As shown in FIG. 5, the dimension in the width direction (X) between the first side surface 411 and the second side surface 415 of the housing 410 is defined as a dimension W1. A dimension in the width direction (X) of the expanded portion 363 of the cleaner body 340 is defined as a dimension W2. Dimension W1 is the same as or smaller than dimension W2. That is, the dimension W1 perpendicular to the central axis C of the cleaner body 340 and in the width direction (X) perpendicular to the depth direction (Y) is equal to or less than the dimension W2 of the extended portion 363.

  When the dimension in the depth direction and the dimension in the width direction satisfy the above relationship, a sense of unity between the housing portion 410 and the cleaner main body 340 can be obtained, and as a result, design can be improved. In addition, the housing portion 410 may be retracted in the depth direction (Y) with respect to the expanded portion 363 of the cleaner body 340.

  The housing portion 410 is preferably made of a water-washable material. By appropriately washing the containing portion 410, the containing portion 410 can be kept clean. Being washable means being chemically stable to water. For example, resins such as polypropylene, polycarbonate and polyethylene terephthalate, metals such as steel, aluminum alloys and stainless steel, or nonmetals such as ceramics are available.

As mentioned above, the receiving portion 410 can be removed from the first cylindrical portion 343. However, it is not limited to this. For example, the housing portion 410 may be integrally formed with a portion of the back surface portion of the first cylindrical portion 343, and the housing portion 410 may be removed from the front surface portion of the first cylindrical portion 343 together with a portion of the back surface portion.
As described above, the housing portion 410 is detachably attached to the cleaner body 340. However, not only this but the accommodating part 410 may be attached to the cleaner body 340 non-removably. The housing portion 410 may be integrally formed with the cleaner body 340.

  Moreover, the attachment structure which can be attached or detached is not restricted to said structure. For example, fastening means such as a set of a nut and a bolt may be employed. Magnetic means such as a permanent magnet and magnetic metal pair may be employed. Also, suction means such as a suction cup may be employed.

  The housing portion 410 may have one or more holes in the bottom portion 431. This can prevent or reduce the accumulation of dust in the internal space of the housing portion 410. Conversely, the housing portion 410 may adopt the bottom portion 431 without a hole. Thereby, dust can be prevented from leaking out from the internal space of the housing portion 410.

  1-5. Holding unit

  The holder 399 is provided on the handle 390, as shown in FIG. The holder 399 holds the auxiliary dust collector 450 housed in the housing 410. In detail, the holding portion 399 is located near the cleaner body 340 in the handle 390. As described above, the cleaner body 340 has the stepped portion 359 on the handle 390 side. The holding portion 399 is located in the vicinity of the step portion 359, so that an object can be prevented from being caught by the holding portion 399. In addition, when the user holds the handle portion 457 of the auxiliary dust collection tool 450 and takes out the auxiliary dust collection tool 450 from the storage unit 410, the user is less likely to get in the way.

  In detail, as shown in FIG. 6, the holding portion 399 includes a pair of plate-like portions 401. The pair of plate-like portions 401 extend in the depth direction (Y) orthogonal to the direction (Z: axial direction) in which the suction tool 310, the cleaner main body 340, and the handle tool 390 are arranged. Each plate-like portion 401 has a rectangular shape long in the axial direction (Z). Thereby, the handle portion 457 of the auxiliary dust collector 450 can be firmly held. The tip in the depth direction (Y) of each plate-like portion 401 does not protrude from the outer circumferential surface 349 of the first cylindrical portion 343. Thus, when the storage portion 410 is slid for mounting and demounting of the storage portion 410, interference of the plate-like portions 401 with the storage portion 410 can be prevented. Each plate-like portion 401 has opposing surfaces 403 facing each other. Thus, when the handle portion 457 of the auxiliary dust collection tool 450 is positioned between the facing surfaces 403, movement of the handle portion 457 in the width direction (X) can be restricted. The holding portion 399 includes a pair of vertically elongated convex portions 405. Each convex portion 405 protrudes from the opposing surface 403 of the plate-like portion 401 toward the other side. Each convex portion 405 is provided at the tip of the plate-like portion 401 in the depth direction (Y).

  The holding portion 399 holds the auxiliary dust collector 450, and more specifically, holds the handle portion 457 of the auxiliary dust collector 450, as shown in FIG. The handle portion 457 has a first portion 459 and a second portion 463. A dimension in the width direction (X) of the first portion 459 is defined as a dimension W3. The dimension in the width direction (X) of the second portion 463 is defined as a dimension W4. The dimension W3 is larger than the dimension W4.

  The interval G1 of the holding portion 399 is larger than the dimension W3 of the first portion 459 of the auxiliary dust collector 450. Thus, the holding portion 399 can arrange the first portion 459 between the pair of plate-like portions 401. The distance G2 between the holding portions 399 is smaller than the dimension W3 of the first portion 459 of the auxiliary dust collector 450. Thus, the holding unit 399 can restrict the movement of the first portion 459 in the depth direction (Y). That is, detachment of the auxiliary dust collector 450 from the holding portion 399 in the depth direction (Y) can be prevented or reduced. The distance G2 between the holding portions 399 is larger than the dimension W4 of the second portion 463 of the auxiliary dust collector 450. Thereby, the bent portion 465 of the second portion 463 can pass between the convex portions 405 of the holding portion 399.

  The auxiliary dust collector 450 is detachably attached to the holding portion 399 by a slide along the axial direction (Z). Each plate-like portion 401 of the holding portion 399 may be elastically deformable in the thickness direction (X). Thus, the auxiliary dust collector 450 can be attached and detached by moving the auxiliary dust collector 450 in the depth direction (Y). In particular, the tip of the convex portion 405 is tapered. Thereby, the attachment / detachment by the movement of the depth direction (Y) of the auxiliary | assistant dust collector 450 can be made easy.

  The holder 399 prevents rattling of the auxiliary dust collector 450 at the time of cleaning. The holding portion 399 also prevents the auxiliary dust collector 450 from being lost when the vacuum cleaner 3 is stored.

The holder 399 is not limited to the above structure as long as the auxiliary dust collector 450 can be detachably held. For example, fastening means such as a set of a nut and a bolt may be employed. Magnetic means such as a permanent magnet and magnetic metal pair may be employed. Also, suction means such as a suction cup may be employed.
The shape of each plate-like portion 401 is not limited to the rectangular shape as long as it has a fixed length in the axial direction (Z). For example, it may be semicircular, trapezoidal or triangular. In the case of the trapezoidal shape and the triangular shape, the dimension in the depth direction (Y) may increase from the upper end to the lower end, or vice versa.

  The holder 399 may be provided on the cleaner body 340 instead of the handle 390. Two holders 399 may be provided on both the handle 390 and the cleaner body 340, respectively. One holder 399 may extend over both the handle 390 and the cleaner body 340.

  1-6. Auxiliary dust collector

  The auxiliary dust collector 450 is a cleaning tool such as a mop, dust collector, brush, broom, scrub, and the like. The auxiliary dust collector 450 includes a head 451 and a handle 457, as shown in FIG. The head portion 451 includes a head main body 453 and mounting means (for example, a mounting button 455). The handle portion 457 includes a first portion 459 and a second portion 463.

  The second portion 463 of the handle 457 has an engagement hole 467 for engaging the attachment button 455. The mounting button 455 is exposed to the outside of the second portion 463 through the engagement hole 467. The mounting button 455 is biased by a spring force to realize a strong engagement with the engagement hole 467. As an example, a U-shaped notch is formed in the plate portion, and the attachment button 455 is provided at the inner portion of the U-shape. The U-shaped internal portion is elastically deformable in the thickness direction with respect to other portions of the plate portion. Thereby, a spring force can be generated. When the mounting button 455 is pushed into the interior of the second portion 463 against the spring force, the engagement between the mounting button 455 and the engagement hole 467 can be released. As a result, the head main body 453 and hence the head portion 451 can be removed from the second portion 463 and thus the handle portion 457. The head 451 may be detachably attached to the handle 457 by any other method. For example, the handle 457 and the head 451 may be attached by screws. Also, the head portion 451 may be attached to the handle portion 457 in a non-removable manner. For example, the head 451 may be formed integrally with the handle 457.

  The first portion 459 of the handle portion 457, as shown in FIG. The first portion 459 has protrusions 461 projecting toward the inner space on a pair of side surfaces facing each other. The second portion 463 of the handle portion 457 has a cylindrical shape with a substantially rectangular cross section, and is fitted inside the first portion 459. The second portion 463 has a guide groove 469 fitted to the protrusion 461 on a pair of side surfaces facing each other. Thus, the second portion 463 is slidably attached to the first portion 459. That is, the handle portion 457 is stretchable. Accordingly, when the auxiliary dust collection tool 450 is stored in the storage unit 410, the handle 457 can be contracted, and when the auxiliary dust collection tool 450 is used, the handle 457 can be extended.

  The handle 457 has a bent portion 465 as shown in FIG. Also, as described above, the first cylindrical portion 343 of the cleaner body 340 has a stepped portion 359 formed by the tapered surface 347 and the upper surface 345. In the state where the auxiliary dust collector 450 is accommodated in the accommodation portion 410 and held by the holding portion 399, the bent portion 465 follows the stepped portion 359. This makes it possible to give a sense of unity in design.

  2. Vacuum cleaner support device

  As shown in FIG. 1, the vacuum cleaner unit 1 comprises a vacuum cleaner 3 and a cleaner support device 5. The vacuum cleaner supporting device 5 supports the vacuum cleaner 3. The vacuum cleaner supporting device 5 here is a charging station for charging a battery built in the vacuum cleaner 3. The vacuum cleaner supporting device 5 includes a suction tool mounting table 510 for mounting the suction tool 310 of the vacuum cleaner 3 and a support 540 for supporting the vacuum cleaner main body 340 of the vacuum cleaner 3.

  2-1. Suction tool placement table

As shown in FIG. 10, the suction tool mounting table 510 has a mounting portion 511 on which the suction tool 310 is mounted and a front surface portion 521 connected to the mounting portion 511. The suction tool mounting table 510 has an internal space 525 below the mounting portion 511. The front surface portion 521 has an insertion port 523 communicating with the internal space 525. The insertion port 523 can receive the head portion 451 of the auxiliary dust collector 450. The placement unit 511 has one or more (seven in the example shown in FIG. 10) communication ports 513 in communication with the internal space 525. Each communication port 513 has a substantially rectangular shape elongated in the depth direction (Y). The plurality of communication ports 513 are arranged in the width direction (X). The communication ports 513 face the suction port 323 at the bottom of the suction tool 310 when the suction tool 310 of the vacuum cleaner 3 is properly placed on the mounting portion 511. In other words, when the switch of the vacuum cleaner 3 is turned on, the communication port 513 is provided so that air and dust in the internal space 525 can be sucked.
The shape of the communication port 513 is not limited to a substantially square shape. For example, it may be circular, oval, triangular or hexagonal. The number of communication ports 513 is not limited to seven. It may be one or more than seven. However, a plurality of small holes rather than one large hole can increase the flow velocity of the fluid passing through the holes, and prevent or reduce the removal of dust.

  The vacuum cleaner 3 can drive the electric blower while being supported by the vacuum cleaner supporting device 5. At this time, the vacuum cleaner 3 sucks the air and dust in the internal space 525 of the suction tool placement table 510 through the communication port 513. On the other hand, the internal space 525 of the suction tool placement table 510 can receive the head portion 451 of the auxiliary dust collection tool 450 through the insertion port 523. The dust attached to the head portion 451 is sucked by the vacuum cleaner 3 through the communication port 513. Thus, the head portion 451 of the auxiliary dust collector 450 can be cleaned.

  The mounting portion 511 has one or more (six in the example shown in FIG. 10) protrusions 515 protruding into the internal space 525. Each protrusion 515 is disposed between the adjacent communication ports 513. For example, the auxiliary dust collector 450 is a mop including a plurality of wings or fibers in its head portion 451. When the head portion 451 of the auxiliary dust collector 450 is moved in the internal space 525, each protrusion 515 gets in between the wings or fibers of the head portion 451 and scrapes out the dust attached to them. Thereby, the head portion 451 can be cleaned more cleanly.

  The plurality of protrusions 515 are disposed in parallel to one another. Thus, the flow of air passing through the plurality of communication ports 513 can be adjusted, and as a result, dust can be efficiently sucked.

  As shown in FIG. 10, the dimension in the height direction (Z) of the insertion port 523 of the front surface portion 521 is defined as a dimension H5. A dimension in the width direction (X) of the insertion port 523 is defined as a dimension W5. The area of the insertion port 523 is determined by the product of the dimension H5 and the dimension W5. On the other hand, the dimension in the height direction (Z) in the natural state of the head portion 451 is defined as a dimension H6. The dimension in the width direction (X) in the natural state of the head portion 451 is defined as a dimension W6. Here, the natural state refers to a state in which the head portion 451 does not receive a compressive force. The cross-sectional area of the head portion 451 is determined by the product of the dimension H6 and the dimension W6. Preferably, the insertion port 523 has an area smaller than the cross-sectional area of the head portion 451. Thus, the head portion 451 is filled in the entire insertion opening 523. Air leakage due to insufficient filling of the insertion port 523 can be prevented or reduced, so that the suction force by the vacuum cleaner 3 can be effectively used.

As shown in FIG. 11, the dimension in the depth direction (Y) of the region where the head portion 451 can be inserted in the internal space 525 is defined as a dimension L5. As shown in FIG. 10, the dimension in the insertion direction (Y) of the head portion 451 is defined as a dimension L6. Dimension L5 is smaller than dimension L6. As a result, even when the head portion 451 is inserted all the way in, the state in which the head portion 451 is filled in the entire insertion opening 523 can be maintained. Therefore, the suction force by the vacuum cleaner 3 can be used effectively.
The suction tool placement table 510 has a T-shape, and a support 540 is provided upright at an extension portion extending rearward. An internal space 525 is formed by utilizing this extended portion. Thereby, the dimension of the depth direction (Y) of the internal space 525 is securable enough, forming the suction tool mounting base 510 slimly. Further, since the extended portion is at the center in the width direction (X), the balance of the support 540 can be improved.

  In addition, there may be no or small influence of air leakage. In this case, the dimension L5 may be equal to or larger than the dimension L6. Thereby, the head portion 451 can be cleaned entirely.

  As shown in FIG. 12, the suction tool placement table 510 includes a positioning portion 527 on the placement portion 511. The positioning portion 527 assists the placement of the suction tool 310 of the vacuum cleaner 3 at an appropriate position. By arranging the suction tool 310 at an appropriate position, the suction port 323 of the suction tool 310 faces one or more communication ports 513 of the mounting portion 511. The positioning portion 527 includes a first projecting piece 529 located at the front end of the mounting portion 511. The placement portion 511 is inclined such that the rear end is higher than the front end. The positioning portion 527 also functions as a stopper for preventing the suction tool 310 from rolling forward. When the suction tool 310 is placed on the placement portion 511, the first protruding piece 529 abuts on the front end of the upper cover 311 of the suction tool 310, and restricts the movement of the suction tool 310 in the depth direction (Y). The positioning portion 527 is an intermediate portion in the depth direction (Y) of the mounting portion 511, and includes two second projecting pieces 531 located at the rear end of the communication port 513. Each of the second projecting pieces 531 abuts the inner wall 315 of the suction tool 310 when the suction tool 310 is placed on the placement portion 511, and movement of the suction tool 310 in the depth direction (Y) and width direction (X) Regulate.

In addition, the 1st protrusion piece 529 and the 2nd protrusion piece 531 are also members which raise the fluid impedance of the clearance gap between the suction tool 310 and the mounting part 511. As shown in FIG. Thus, air leakage through the gap between the suction tool 310 and the placement unit 511 can be prevented or reduced, and as a result, the suction force by the vacuum cleaner 3 can be effectively used for cleaning the head portion 451.
In addition, the suction tool 310 has the groove | channel 329 in communication with the suction port 323 in the both sides | surfaces of the suction tool 310. As shown in FIG. Air can also be sucked from the lateral direction through the grooves 329. The second projecting piece 531 of the suction tool mounting table 510 may have a function of closing the groove 329. This can prevent or reduce air leakage through the grooves 329.

  As shown in FIG. 12, the suction port 323 at the bottom of the suction tool 310 includes a first area 325 in which the rotating brush 319 is present, and a second area 327 between the rotating brush 319 and the inner wall 315. The second area 327 is adjacent to the first area 325 in the depth direction (Y). Since the first region 325 of the suction port 323 includes the rotating brush 319, it has a relatively high fluid impedance. Conversely, the second region 327 of the suction port 323 does not include the rotating brush 319 and thus has a relatively low fluid impedance. Thus, air is mainly sucked through the second region 327. That is, the second area 327 can suction dust more smoothly than the first area 325.

  On the other hand, as shown in FIG. 11, each protrusion 515 of the mounting portion 511 has a first blade portion 517 and a second blade portion 519. The second blade portion 519 has a larger dimension in the height direction (Z) than the first blade portion 517. Thus, the second blade portion 519 can scrape more dust than the first blade portion 517.

In this manner, a large amount of dust is scraped out in the lower part of the second region 327, so that it is possible to prevent or reduce dust remaining in the internal space 525.
The shape of the protrusion 515 is not limited to the above shape, and may have a fixed height from the front end to the rear end. In addition, the height may be gradually increased from the front end to the rear end, and conversely, the height may be gradually decreased from the front end to the rear end.
The positioning portion 527 is not limited to the above configuration, and may be provided along the entire periphery of the suction tool 310. Further, instead of the projecting piece protruding from the mounting portion 511, the recessed portion may be recessed from the mounting portion 511 that conforms to the shape of the suction tool 310.
The insertion port 523 may be provided not on the front surface portion 521 but on the side surface.

  2-2. Pillar

  The post 540 is disposed at the rear end of the suction tool placement table 510 as shown in FIG. The post 540 has a tapered surface 541 and a concave surface 543 at its top. The tapered surface 541 fits on the end surface 371 of the expanded portion 363 of the cleaner body 340. The concave surface 543 fits on the outer circumferential surface of the second cylindrical portion 373 of the cleaner body 340. The cleaner body 340 is held by the tapered surface 541 and the concave surface 543 and maintained in a standing state.

  The post 540 preferably comprises a charging mechanism 545 for charging the battery of the vacuum cleaner 3. The charging mechanism 545 includes, for example, a circuit module 547 provided in the support 540 and a connector receiving portion 549 provided on the tapered surface 541. The circuit module 547 generates, for example, DC power suitable for charging a battery from AC power of a commercial power supply. The connector receiving portion 549 fits the connector 379 (see FIG. 5) provided on the cleaner body 340, and electrically connects the circuit module 547 and the battery. The support 540 can charge the battery inside the cleaner body 340 while keeping the cleaner body 340 standing. Even during charging of the battery, the vacuum cleaner 3 is designed to drive the electric blower when switched on.

Second Embodiment
The vacuum cleaner unit 1001 which concerns on 2nd Embodiment is provided with the vacuum cleaner 1003 and the vacuum cleaner support apparatus 1005, as FIG. 13 shows.
The vacuum cleaner 1003 is a so-called stick-type vacuum cleaner provided with a suction tool 1310, a vacuum cleaner main body 340 and a handle tool 390 in this order.
Also in the second embodiment, the width direction (X), the depth direction (Y) and the axial direction (Z) have the same definitions as in the first embodiment.
Similar to the first embodiment, the vacuum cleaner 1003 includes a housing portion 410 for housing the auxiliary dust collector 450 so as to be freely removable from the handle 390 side. The housing portion 410 is attached to the cleaner body 340. The vacuum cleaner 1003 is charged from the vacuum cleaner supporting device 1005.
The vacuum cleaner supporting apparatus 1005 includes a suction tool placement table 1510 for mounting the suction tool 1310 of the vacuum cleaner 1003 and a support 540 for supporting the vacuum cleaner main body 340 of the vacuum cleaner 3.
In the second embodiment, a part of the suction tool 1310 of the vacuum cleaner 1003 and the suction tool placement table 1510 of the vacuum cleaner supporting apparatus 1005 are mainly different from those of the first embodiment. Therefore, these differences are mainly described below. The same reference numerals are used for the same configuration as the first embodiment, and the description of the configuration is omitted.

1. Suction Tool As shown in (a) of FIG. 14, the suction tool 1310 internally has a suction space 1312 that communicates with the outside through a suction port 1323 at the bottom. The suction space 1312 is connected (communicated) with the inside of the dust collection pipe 1320 through the communication port 1317 of the inner wall 1315 which constitutes the space. The dust collection pipe 1320 is detachably connected to (the internal space of) the second cylindrical portion 373 of the cleaner body 340.

1-1. Suction port The suction port 1323 includes a first area 1325 and a second area 1327, and a suction space 1312 exists in a first space 1314 present on the back side of the first area 1325 and a back side of the second area 1327. There are two spaces 1316.
In order to distinguish the lead lines of the first space 1314 from the lead lines of the first region 1325, the rotary brush 319, the inner wall 1315, and the like, the tip is an arrow. Similarly, in order to distinguish the lead lines of the second space 1316 from the lead lines of the second region 1327, the inner wall 1315, and the like, the tip thereof is an arrow.

The first space 1314 has a shape close to a long cylindrical shape in the width direction (X), as shown in FIG. In the first space 1314, a rotating brush 319 long in the width direction (X) and having the width direction as a rotation axis is accommodated.
The second space 1316 is present between the first space 1314 (rotation brush 319) and the communication port 1317. Accordingly, the dust scraped out by the rotating brush 319 travels from the second space 1316 to the communication port 1317.
That is, the suction tool 1310 has two spaces adjacent to the depth direction (Y), one of which is the first space 1314 for housing the rotating brush 319, and the other one of which is the second space for generating the swirling air flow. It is 1316.
The rotating brush 319 is provided with one or more brushes, for example, in a spiral shape on the rotating shaft. The brush may use a plate-like body such as a rubber material, or may use a plurality of fibrous bodies such as resin. When a fibrous body is used, a static elimination fiber such as an organic conductive fiber in which copper sulfide is chemically bonded to acrylic fiber or nylon fiber may be used as all or part of the fibrous body.

As shown in (b) of FIG. 14, the middle portion in the width direction (X) of the second space 1316 is a straight portion 1316 a whose cross-sectional shape does not change in the width direction (X). Both side portions in the width direction (X) of the second space 1316 are tapered portions 1316 b having substantially the same cross-sectional shape and gradually decreasing in area toward the end.
The shape (inner wall shape) of the cross section orthogonal to the width direction (X) in the second space 1316 has a circular shape or a shape resembling a circular shape in which the cleaning surface side is cut off.

As shown in FIG. 14, the communication port 1317 is provided on the opposite side to the first space 1314 in the second space 1316. By configuring the cross-sectional shape of the second space 1316 and the position of the communication port 1317 as described above, the swirling air flow is easily generated in the second space 1316. Further, since the second space 1316 is divided by the first space 1314 and the dividing wall 1315a, the generation of the swirling air flow is not hindered by the rotating brush 319. The end in the width direction (X) of the tapered portion 1316 b communicates with the outside through the groove 329.
The communication port 1317 has a long shape in the width direction (X). That is, it has a long shape along the axis of the rotating brush 319. The communication port 1317 is provided in the straight portion 1316 a in the second space 1316.

Between the first space 1314 and the second space 1316, there is provided a projecting portion 1318 that protrudes to the first space 1314 side. The overhanging portion 1318 here is formed of an overhanging member different from the bottom cover 1313 that constitutes the suction space 1312.
A partition wall 1315a that partitions the first space 1314 and the second space 1316 is included in the inner wall 1315, and the overhanging member is detachably attached to the cutout in the middle of the partition wall 1315a in the width direction (X) .

The overhanging portion 1318 is provided to be able to contact the rotating brush 319. The overhanging portion 1318 overhangs in the direction opposite to the rotational direction of the rotary brush 319 (which is the arrow direction in the figure), as shown in FIG. In other words, contact with the brush causes the brush of the rotating brush 319 to protrude in the direction of raising. Thereby, the dust scraped off by the rotating brush 319 around the suction port 1323 is separated from the rotating brush 319. The overhanging portion 1318 here is made of, for example, a rubber material. Thereby, excessive wear of the rotating brush 319 can be suppressed. Note that the overhanging portion 1318 may be made of a material capable of removing electricity to prevent adsorption of dust due to static electricity.
The dust separated from the rotating brush 319 is drawn to the adjacent second space 1316 side, and then drawn from the communication port 1317 to the cleaner body 340 via the dust collection pipe 1320.

The overhanging portion 1318 is provided at an intermediate portion in the width direction (X) when the suction port 1323 is viewed from the bottom side (that is, in the state of (b) in FIG. 14). The overhanging portion 1318 is longer than the total length of the straight portion 1316 a in the second space 1316 and shorter than the total length of the second space 1316 as shown in (b) of FIG. 16. The total length of the overhang portion 1318 in this embodiment is a length obtained by adding 0 (%) to 50 (%) of each of the tapered portions 1316b on both sides to the total length of the straight portion 1316a, but is limited thereto Instead, the length may be adjusted to the entire rotating brush 319.
The length in the width direction (X) of the overhang portion 1318 is longer than the length in the width direction of the communication port 1317 as shown in (b) of FIG. 14.

The overhanging portion 1318 is opposed to the communication port 1317 across the second space 1316 as shown in (b) of FIG. 14. As a result, the dust scraped off by the overhanging portion 1318 is efficiently sucked from the communication port 1317.
The lower end in the axial direction (Z) of the overhanging portion 1318 is configured not to reach the cleaning surface as shown in (b) of FIG. 16 and FIG. As a result, the dust scraped off by the overhang portion 1318 efficiently moves to the second space 1316.
The overhanging portion 1318 is located on the opposite side to the cleaning surface than the lower end (end on the cleaning surface side) of the end in the width direction (X) of the section wall 1315a, as shown in FIG. . That is, the lower end of the overhanging portion 1318 is higher than the lower end of the partition wall 1315 a that constitutes the tapered portion 1316 b of the second space 1316 based on the cleaning surface. Accordingly, the sealing performance of the second space 1316 in the tapered portion 1316 b can be enhanced, and the swirling air flow from the end in the width direction (X) toward the communication port 1317 can be strengthened in the second space 1316.
The lower end in the axial direction (Z) of the overhanging portion 1318 is higher than the lower end of the communication port 1317, as shown in FIG.

1-2. Dust Collection Pipe (1) Overall Configuration As shown in FIG. 18, the dust collection pipe 1320 is a communication side pipe 1322 disposed facing the second space 1316, and a main body pipe disposed on the cleaner body 340 side. 1324 and a connecting pipe 1326 rotatably connecting the main body side pipe 1324 to the communication side pipe 1322 with the X axis parallel to the width direction (X) and the Y axis parallel to the depth direction (Y) as a rotation axis Equipped with The connecting pipe 1326 is composed of a connecting lower pipe 1328 and a connecting upper pipe 1330.
The upstream opening of the communication side pipe 1322 is attached to the bottom cover 1313 in a fixed state in which the opening on the inner wall 1315 of the bottom cover 1313 is fitted. When the communication side pipe 1322 is attached to the bottom cover 1313, the upstream side opening of the communication side pipe 1322 functions as a communication port 1317.
The downstream end of the main body side pipe 1324 functions as a connection with the cleaner main body 340, and also electrically connects the rotary brush 319 in order to rotationally drive the rotary brush 319 by a drive unit (not shown).
The connecting pipe 1326 is rotatably connected to the communication side pipe 1322 around the Y axis. The main body side pipe 1324 is rotatably connected to the connection pipe 1326 around the X axis. The dust collection pipe 1320 has a restriction release structure that restricts the connection pipe 1326 from rotating about the Y axis with respect to the communication side pipe 1322 and releases the rotation restriction.

(2) Communication side pipe and connection pipe The connection between the communication side pipe 1322 and the connection pipe 1326 is, as shown in FIG. 19A, the downstream cylindrical portion 1322a of the communication side pipe 1322 is a connection lower pipe 1328. It is fitted in the cylindrical fitting portion 1328a at the upstream end portion of the upper end portion, and in this state, is fixed by the “C” -shaped fixing tool 1331.
In this case, the cylindrical portion 1322a is inserted into the fitting portion 1328a, so the cylinder axis of the cylindrical portion 1322a becomes the Y axis which is the rotation axis, and the connection pipe 1326 can rotate relative to the communication side pipe 1322. In this state, the cylindrical portion 1322a is disengaged from the fitting portion 1328a.

  The communication side pipe 1322 has a circumferential groove 1322b extending in the circumferential direction in the cylindrical portion 1322a, and the connection pipe 1326 is a through hole 1328b, 1328c in a portion corresponding to the circumferential groove 1322b of the cylindrical portion 1322a in the fitting portion 1328a (FIG. 18). See). The convex portions 1331 a and 1331 b of the “C” -shaped fixing tool 1331 are inserted through the through holes 1328 b and 1328 c of the connection lower pipe 1328 to fit in the circumferential groove 1322 b of the communication side pipe 1322. This can prevent the connection pipe 1326 (the connection lower pipe 1328) from being detached from the communication side pipe 1322.

It will be described in detail.
The fitting portion 1328a of the connection lower pipe 1328 has a groove 1328d extending in the circumferential direction for the fixing tool 1331, and through holes 1328b and 1328c are provided in the bottom wall of the groove 1328d. Specifically, the positions of the through holes 1328 b and 1328 c correspond to the positions of the convex portions 1331 a and 1331 b of the fixing tool 1331. The “C” -shaped fixture 1331 has an arc shape longer than a semicircle, the convex portion 1331 a is substantially at the center of the arc, and the convex portion 1331 b is at both ends of the arc. As a result, the fixing tool 1331 can be prevented from easily coming off the lower connection pipe 1328. In addition, the fixing tool 1331 is fixed to the connection pipe 1326 and does not rotate only by the fixing tool 1331.

The restriction releasing structure is, as shown in FIG. 19, from an engaged portion 1322 c provided on the communication side pipe 1322 and an engaging portion 1331 c provided on the connection pipe 1326 side (in this case, the fixing tool 1331). Configured
The engaged portion 1322c has a recessed portion 1322d which is recessed in the direction parallel to the cylinder axis, on the side opposite to the side where the fixing tool 1331 is present. The engaging portion 1331c has a convex portion 1331d that protrudes in the direction parallel to the cylinder axis on the communication side pipe 1322 side. When the convex portion 1331d engages (fits in) the recessed portion 1332d, the rotation of the connection pipe 1326 with respect to the communication side pipe 1322 is restricted.
The external shape of the concave portion 1322 d and the convex portion 1331 d has an arc shape as viewed from a direction orthogonal to the engaging direction ((c) in FIG. 19). This makes it possible to release the rotation restriction smoothly.

When the restriction releasing structure is seen from the direction orthogonal to the engaging direction (as shown in (c) of FIG. 19), the engaged portion 1322c is inclined such that it gets farther from the fixing tool 1331 as it gets away from the recessed portion 1322d in the circumferential direction. The portions 1322 e are provided on both sides of the recessed portion 1322 d. Thereby, even if the engaging portion 1331c (convex portion 1331d) is at a position (state in which the rotation is not restricted) away from the engaged portion 1322c in the circumferential direction, the convex portion 1331d is rotated by the rotation on the connection pipe 1326 side. Smoothly engage (fit) the recessed portion 1322d.
The engaged portion 1322c is provided on the outer cylindrical portion 1322f coaxial with the cylindrical portion 1322a as shown in (a) and (b) of FIG. The engaged portion 1322c is positioned on the track of the portion 1331c.

The fixing tool 1331 has an engaging portion 1331c so as to be elastically deformable in a direction parallel to the cylinder axis. Specifically, the fixing member 1331 has a U-shaped portion 1331 f projecting in an inverted “U” shape radially outward from the “C” -shaped main body portion 1331 e, and is engaged with the U-shaped portion 1331 f A mating portion 1331 c is provided.
Thereby, when the connecting pipe 1326 is rotated with respect to the communication side pipe 1322, the engaging portion 1331c is elastically deformed to the opposite side to the communication side pipe 1322, and the engagement of the convex portion 1331d with the concave portion 1322d or the concave portion The engagement release from 1322d can be smoothly performed.

The fixing tool 1331 regulates that the communication side pipe 1322 is not detached from the connection pipe 1326, and therefore has rigidity (thickness) which is not broken even if a load is applied. However, by providing the engaging portion 1331c in the U-shaped portion 1331f having a space between itself and the main body portion 1331e, the U-shaped portion 1331f engages with the appropriate load (here, the cylindrical portion 1322a of the communication side pipe 1322 It is possible to prevent elastic deformation in a direction parallel to the axial direction of the cylinder and to make it difficult to release the engagement between the convex portion 1331d and the concave portion 1322d.
As described above, by adopting the structure of the U-shaped portion 1331 f, by appropriately selecting the space between the main body portion 1331 e and the U-shaped portion 1331 f, the degree of engagement or engagement between the convex portion 1331 d and the recessed portion 1322 d You can adjust the degree of cancellation. The portion where the convex portion 1331d is provided may have a shape other than the U-shaped portion 1331f, for example, a shape such as an L-shaped portion or an O-shaped portion.

  In addition, a driving unit (not shown) for rotationally driving the rotating brush 319 is provided in the suction tool 1310. Generally, there is a communication side pipe 1322 or the like at the central portion in the width direction (X) of the suction tool 1310, and the drive portion is arranged in a state of being shifted from the center in the width direction of the suction tool 1310 to one side in the width direction ing. For this reason, when the suction tool 1310 is lifted during use, a load is generated in which the communication side pipe 1322 tends to rotate relative to the connection pipe 13326 due to the influence of the rotational moment due to the weight of the drive unit. By configuring the U-shaped portion 1331 f not to elastically deform (engagement state is not released) with respect to the load of the rotation, it is possible to eliminate the wobble when lifting the suction tool 1310.

2. Vacuum Cleaner Support Device The vacuum cleaner support device 1005 supports the vacuum cleaner 1003. The vacuum cleaner supporting device 1005 here is a charging station for charging a battery built in the vacuum cleaner 1003. The vacuum cleaner supporting apparatus 1005 is provided with a suction tool placement table 1510 for mounting the suction tool 1310 of the vacuum cleaner 1003 and a support 540 for supporting the vacuum cleaner 3 (vacuum cleaner main body 340) as shown in FIG. The suction tool placement table 1510 has a nozzle holding portion 1535 for holding a gap nozzle 1007 which is mounted instead of the suction tool 1310.

It has an internal space 525 to be opened. The placement unit 511 has a plurality of communication ports 513 communicating with the internal space 525 along the axial direction of the rotating brush 319. The placement unit 511 includes a first projecting piece 529 as a positioning unit for the suction tool 1310 in the placement unit 511.

The base portion 1530 has a recessed portion 1533 recessed on the mounting surface side on the surface on the mounting portion 511 side, and a charge removing member, here, an iron plate 1534 is disposed in the recessed portion 1533. The base portion 1530 has a guide portion 1538 so that the head portion 451 of the auxiliary dust collection tool 450 can be smoothly inserted into the insertion port 523. Guide portion 1538 is configured with a forward and downward slope.
The iron plate 1534 has a function of removing the charge on the head portion 451 of the auxiliary dust collector 450. The iron plate 1534 is disposed at a position close to the installation surface and has a function of supporting the vacuum cleaner 1003 in a stable state. The iron plate 1534 is larger than the dimension in the width direction (X) of the insertion port 523 and extends to the opposite side of the internal space 525 from the side wall 525 a forming the internal space 525. This eliminates the need for a special configuration for fixing the iron plate 1534, which can be implemented easily.

The suction tool placement table 1510 has a nozzle holding portion 1535 behind the placement portion 511 when the suction tool placement table 1510 is viewed from above. The nozzle holding portion 1535 here is configured of an overhanging portion 1536 overhanging from the base portion 1530 and a cylinder portion 1537 extending upward from the overhanging portion 1536. The gap nozzle 1007 is detachably supported by fitting its cylindrical portion 1071 to the outside of the cylindrical portion 1537.
The overhanging portion 1536 is in a rectangular region having two sides each having the dimension in the width direction (X) of the placement portion 511 or the base portion 1530 and the dimension in the depth direction (Y) obtained by combining the placement portion 511 and the support 540 Provided to fit within the Thus, the gap nozzle 1007 can be held without substantially enlarging the installation area of the vacuum cleaner supporting device 1005.

Third Embodiment
In the first embodiment, the handle portion 457 of the auxiliary dust collection tool 450 is held by the pair of plate-like portions 401 of the vacuum cleaner 3 so as to be held therebetween.
However, in the third embodiment, the auxiliary dust collector 2450 is held by the vacuum cleaner 2003 using the engagement structure. Hereinafter, the holder of the vacuum cleaner 2003 and the auxiliary dust collector 2450 will be described.

The vacuum cleaner 2003 has a holding portion for holding the auxiliary dust collector 2450 as shown in FIG. The holding portion here is constituted by an engaging portion 2399 which engages with the engaged portion 2458 of the handle 2457 of the auxiliary dust collector 2450.
The engagement relationship may be such that the engaged portion of the vacuum cleaner is engaged by the engagement portion of the handle of the auxiliary dust collection tool.

Here, the engaged portion 2458 of the auxiliary dust collector 2450 is configured by an inverted U-shaped plate portion 2458 a that extends in an inverted “U” shape from the end of the handle 2457 opposite to the head portion (451). The engaging portion 2399 is constituted by an L-shaped plate portion 2399a extending in an “L” shape on the opposite side to the head portion (451) of the auxiliary dust collector 2450.

The restriction releasing structure is a second pipe side (one example is a connection pipe) with respect to the first pipe side (one example is a peripheral portion of the first pipe or the first pipe which is the communication side pipe). In the case where the peripheral members of 2 pipes are rotatably connected, the second pipe side has an engaging portion that engages with the engaged portion on the first pipe side to restrict the rotation of the first pipe. At least one of the engaged portion and the engaging portion is configured to be elastically deformable when the second pipe attempts to rotate with respect to the first pipe. Thereby, the engagement relationship can be easily released and returned.
In the second embodiment, the engaging portion 1331 c is provided in the fixing tool 1331 (which is an example of the peripheral member) fixed to the second pipe, but even if the connecting portion is provided with the engaging portion Good. In other words, it is sufficient that the member rotating integrally with the second pipe has the engaging portion.
In the second embodiment, the engaged portion 1322c is provided on the communication side pipe 1322 which is the first pipe, but the engaged portion is on the bottom cover (an example of the peripheral member) to which the first pipe is attached. Alternatively, the engaging portion may be provided, or the engaged portion or the engaging portion may be provided on the upper cover (which is an example of the peripheral member).

In the second embodiment, the engaging portion 1331c of the fixing tool 1331 is configured to be elastically deformable, but the engaged portion on the first pipe side may be configured to be elastically deformable, or the engaged portion The portion and the engagement portion may be configured to be elastically deformable.
