The vacuum cleaner body 340 includes a cylindrical housing 341. The cylindrical housing 341 includes a first cylindrical portion 343, a cylindrical expansion portion 363, and a second cylindrical portion 373. The expansion portion 363 is located between the first cylinder portion 343 and the second cylinder portion 373 and has a central axis common to the first cylinder portion 343 and the second cylinder portion 373. The first cylindrical portion 343 has the same outer diameter as the second cylindrical portion 373. The expansion 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. As described above, the vacuum cleaner main body 340 has an expansion portion 363 having a large outer peripheral dimension on the way from the handle 390 side to the suction tool 310 side. In addition to the outer peripheral surface 365, the expansion portion 363 has an end surface 369 on the handle 390 side connected to the first cylindrical portion 343 and an end surface 371 on the suction tool side connected to the second cylindrical portion 373. Both the end face 369 and the end face 371 are tapered.

The shape of the vacuum cleaner body 340 is not limited to this, and may have a constant outer diameter from the handle 390 side to the suction tool 310 side, and the outer diameter dimension is small on the way from the handle 390 side to the suction tool 310 side. It may have a reduced portion. Further, the shape of the vacuum cleaner main body 340 is not limited to a cylindrical shape, for example, a cylindrical shape having a polygonal cross section such as a triangular cross section, a square cross section, a hexagonal cross section, an octagonal cross section, a combination thereof, or an asymmetrical shape. It may be in the shape of a cylinder.

The vacuum cleaner main body 340 includes parts such as an electric blower, a battery, a circuit module, a dust collecting pack mounting portion, and an indicator 377. 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 expansion portion 363 accommodates the electric blower. The second cylindrical portion 373 accommodates the dust collecting pack mounting portion and the dust collecting pack. The battery stores the power received from the commercial power source via the circuit module. The battery supplies the stored electric power to the electric blower via the circuit module. The electric blower creates a negative pressure to suck in the dust. The dust collection pack mounting portion attaches the dust collection pack that collects the sucked dust to and from the dust collection pack. The circuit module performs charge / 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 remaining battery level, the operation mode, and the filling rate of the dust collection pack. The first cylindrical portion 343 has an oval window 351 on its outer peripheral surface 349. The indicator 377 is visibly arranged to the outside through the oval window 351.

1-4. Containment section

As shown in FIG. 1, the accommodating portion 410 has an opening 433 for accommodating the auxiliary dust collector 450. The auxiliary dust collector 450 is freely taken out from the handle 390 side and accommodated in the accommodating portion 410. More specifically, the accommodating portion 410 has a bottomed cylindrical shape in which the opening 433 faces the handle 390 side. As a result, the auxiliary dust collector 450 can be easily taken out while using the vacuum cleaner 3. As described above, the vacuum cleaner 3 has a built-in battery for driving the electric blower. Therefore, the vacuum cleaner 3 has high mobility. Such a highly mobile vacuum cleaner 3 includes an accommodating portion 410 accommodating the auxiliary dust collector 450. Therefore, cleaning can be performed by the electric vacuum cleaner 3 while using the auxiliary dust collector 450 without impairing the high mobility of the auxiliary dust collector 450.

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

The first side surface portion 411 is substantially parallel to the second side surface portion 415. The first side surface portion 411 has two vertically elongated projecting pieces 413 on the facing surface facing the second side surface portion 415. Here, "vertical" means a direction along the cylinder axis of the accommodating portion 410. The two projecting pieces 413 are arranged at two places 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 facing surface facing the first side surface portion 411. The projecting piece 413 has a vertically long rectangular shape when the accommodating portion 410 is viewed from the front side. The four projecting pieces 413 are provided at locations near the four corners of the accommodating portion 410, respectively. As a result, the accommodating portion 410 can be stably fixed to the first cylindrical portion 343. The shape and position of the protruding 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 so that the front surface portion 425 is attached so as to face the first cylindrical portion 343. It suffices if it is done. For example, the projecting piece 413 may project from the front surface portion 425 in an L shape.

The front surface portion 425 has a concave surface shape that matches the outer peripheral surface 349 of the first cylindrical portion 343 of the vacuum cleaner main body 340. The front surface portion 425 has two vertically elongated ridge portions 427 and one horizontally elongated engaging convex portion 429. Here, "horizontal" means a direction (circumferential direction) perpendicular to the cylinder axis of the accommodating 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 so as to expand on the opening side. By expanding the area of the opening 433, the head portion 451 of the auxiliary dust collector 450 can be easily inserted into the accommodating portion 410. Further, when the auxiliary dust collector 450 is taken out from the accommodating portion 410, the handle portion 457 can be tilted so as to be separated from the handle portion 390. The inclined portion 423 is for gradually narrowing the internal space of the accommodating portion 410 from the opening 433 toward the bottom surface portion 431. As a result, the head portion 451 of the auxiliary dust collector 450 can be smoothly moved from the opening 433 to the bottom surface portion 431. The back surface portion 419 is not limited to this, and may be substantially parallel to the front surface portion 425. 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 from the bottom surface portion 431 side toward the opening 433 side. In this case, the width may be gradually widened from the bottom surface portion 431 to the middle, and may be tilted from the middle to the opening 433 side so as to be wider than before.

As shown in FIG. 3, the first cylindrical portion 343 of the vacuum cleaner body 340 has four vertically elongated guide grooves 353 on its outer peripheral surface 349. Here, "vertical" means a direction along the cylinder axis of the first cylindrical portion 343. The four guide grooves 353 each receive the four projecting pieces 413 of the accommodating portion 410 and guide the accommodating portion 410 to an appropriate position.

The first cylindrical portion 343 has four vertically elongated protruding pieces 355 on its outer peripheral surface 349. The four projecting pieces 355 are on the sides of the four guide grooves 353, respectively, arranged behind the four projecting pieces 355, and can engage with the four projecting pieces 413 of the accommodating portion 410, respectively. Specifically, when the projecting piece 355 engages with the projecting piece 413, the front surface of the projecting piece 355 comes into contact with the rear surface of the projecting piece 413. When the accommodating portion 410 (protruding piece 413) slides along the guide groove 353 to the lower end of the guide groove 353, the four projecting pieces 413 of the accommodating portion 410 engage with the four projecting pieces 355 of the first cylindrical portion 343, respectively. do. As a result, the movement of the first cylindrical portion 343 of the accommodating portion 410 in a direction other than the tubular axial direction is restricted.
In a state where the accommodating 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 peripheral surface 349 of the first cylindrical portion 343. Therefore, it is possible to prevent dust from entering between the accommodating portion 410 and the first cylindrical portion 343. In addition, a sense of unity between the accommodating portion 410 and the first cylindrical portion 343 can be obtained.

As a result, the accommodating portion 410 is detachably attached to the first cylindrical portion 343 and, by extension, the vacuum cleaner main body 340. Therefore, the accommodating portion 410 can be removed from the vacuum cleaner main body 340 to clean the accommodating portion 410.

The first cylindrical portion 343 has one horizontally long engaging recess 357 on its outer peripheral surface 349. Here, "horizontal" means a direction (circumferential direction) perpendicular to the cylinder axis of the first cylindrical portion 343. The engaging concave portion 357 can be engaged with the engaging convex portion 429 of the accommodating portion 410. When the accommodating portion 410 (projecting piece 413) slides along the guide groove 353 to the lower end of the guide groove 353, the engaging convex portion 429 is engaged (fitted) with the engaging concave portion 357. As a result, the movement of the first cylindrical portion 343 of the accommodating portion 410 in the tubular axial direction is restricted. However, the engagement between the engaging convex portion 429 and the engaging concave portion 357 is designed to be relatively loose. Therefore, the engagement between the engaging convex portion 429 and the engaging concave portion 357 can be disengaged by the intentional and forcible slide of the accommodating portion 410. This makes it possible to attach / detach the accommodating portion 410 to / from the first cylindrical portion 343, while preventing or reducing unintentional detachment of the accommodating portion 410 from the first cylindrical portion 343.

The front surface portion 425 of the accommodating portion 410 has a vertically elongated ridge portion 427 as described above. These ridges 427 form a clearance between the front surface 425 of the accommodating portion 410 and the outer peripheral surface 349 of the first cylindrical portion 343. The accommodating portion 410 contacts the first cylindrical portion 343 at the ridge portion 427 instead of the front surface portion 425. As a result, the contact area of the accommodating portion 410 with the first cylindrical portion 343 can be reduced, and as a result, the sliding of the accommodating portion 410 on the first cylindrical portion 343 can be smoothly performed.

The accommodating portion 410 is attached to the first cylindrical portion 343 as shown in FIG. The bottom surface portion 431 of the accommodating portion 410 is along the end surface 369 on the handle 390 side in the expansion portion 363 of the vacuum cleaner main body 340. As a result, it is possible to create a sense of unity between the accommodating portion 410 and the vacuum cleaner main body 340.

As shown in FIG. 4, the dimension in the depth direction (Y) between the back surface portion 419 of the accommodating portion 410 and the central axis C of the vacuum cleaner main body 340 is defined as the dimension L1. The dimension in the depth direction (Y) between the outer peripheral surface 365 of the extended portion 363 of the vacuum cleaner main body 340 and the central axis C of the vacuum cleaner main body 340 is defined as the dimension L2. The dimension in the depth direction (Y) between the back surface portion of the wiring cover 367 and the central axis C of the vacuum cleaner main body 340 is defined as the dimension L3. Dimension L1 is equal to or greater than dimension L2. Further, the dimension L1 is the same as or larger than the dimension L3. That is, the dimension L1 in the depth direction (Y) away from the mounting portion of the accommodating portion 410 on the outer peripheral surface 349 is the dimension L2 of the expansion portion 363, which is a dimension perpendicular to the central axis C of the vacuum cleaner main body 340. Is more than the same. In other words, the accommodating portion 410 is flush with or protrudes in the depth direction (Y) with respect to the extended portion 363 of the vacuum cleaner main body 340.
The central axis C of the first cylindrical portion 343 is displaced from the central axis C of the expansion portion 363, whereby the accommodating portion 410 is flush with or retracted in the depth direction (Y) with respect to the expansion portion 363. You may.
The wiring cover 367 internally houses the wiring connecting the connector 379 (see FIG. 5) and the battery in the first cylindrical portion 343. The wiring cover 367 is exposed to the outside of the expansion portion 363, but the wiring cover 367 is not limited to this. For example, the wiring cover 367 may be housed inside the expansion portion 363.

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

When the dimension in the depth direction and the dimension in the width direction satisfy the above relationship, it is possible to give a sense of unity between the accommodating portion 410 and the vacuum cleaner main body 340, and as a result, the design can be improved. Further, the accommodating portion 410 may be retracted in the depth direction (Y) with respect to the extended portion 363 of the vacuum cleaner main body 340.

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

As described above, the accommodating portion 410 can be removed from the first cylindrical portion 343. However, it is not limited to this. For example, the accommodating portion 410 may be integrally formed with a part of the back surface portion of the first cylindrical portion 343, and the accommodating portion 410 may be removed from the front surface portion of the first cylindrical portion 343 together with a part of the back surface portion thereof.
As described above, the accommodating portion 410 is detachably attached to the vacuum cleaner main body 340. However, the present invention is not limited to this, and the accommodating portion 410 may be attached to the vacuum cleaner main body 340 so as not to be removable. The accommodating portion 410 may be integrally formed with the vacuum cleaner main body 340.

Further, the detachable mounting structure is not limited to the above structure. For example, a fastening means such as a nut and bolt pair may be adopted. Magnetic means such as a set of permanent magnets and magnetic metals may be employed. Further, a suction means such as a suction cup may be adopted.

The accommodating portion 410 may have one or more holes in the bottom surface portion 431. As a result, it is possible to prevent or reduce the accumulation of dust in the internal space of the accommodating portion 410. On the contrary, the accommodating portion 410 may adopt the bottom surface portion 431 without holes. This makes it possible to prevent dust from leaking from the internal space of the accommodating portion 410.

1-5. Holding part

The holding portion 399 is provided on the handle 390 as shown in FIG. The holding unit 399 holds the auxiliary dust collector 450 housed in the housing unit 410. Specifically, the holding portion 399 is located in the vicinity of the vacuum cleaner main body 340 in the handle 390. As described above, the vacuum cleaner main body 340 has a stepped portion 359 on the handle 390 side. Since the holding portion 399 is located in the vicinity of the step portion 359, it is possible to prevent an object from being caught on the holding portion 399. Further, when the user holds the handle portion 457 of the auxiliary dust collector 450 and takes out the auxiliary dust collector 450 from the accommodating portion 410, it does not easily get in the way.

The holding portion 399 includes a pair of plate-shaped portions 401, as shown in FIG. 6 in detail. The pair of plate-shaped portions 401 extend in the depth direction (Y) orthogonal to the direction (Z: axial direction) in which the suction tool 310, the vacuum cleaner main body 340, and the handle tool 390 are arranged. Each plate-shaped portion 401 has a long rectangular shape in the axial direction (Z). As a result, the handle portion 457 of the auxiliary dust collector 450 can be firmly held. The tip of each plate-shaped portion 401 in the depth direction (Y) does not protrude from the outer peripheral surface 349 of the first cylindrical portion 343. Thereby, when the accommodating portion 410 is slid for attaching / detaching the accommodating portion 410, it is possible to prevent each plate-shaped portion 401 from interfering with the accommodating portion 410. Each plate-shaped portion 401 has facing surfaces 403 facing each other. Thereby, when the handle portion 457 of the auxiliary dust collector 450 is positioned between the facing surfaces 403, the 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 projects from the facing surface 403 of the plate-shaped portion 401 toward the other party. Each convex portion 405 is provided at the tip end portion in the depth direction (Y) of the plate-shaped portion 401.

As shown in FIG. 7, the holding portion 399 holds the auxiliary dust collector 450, and more specifically, holds the handle portion 457 of the auxiliary dust collector 450. The handle portion 457 has a first portion 459 and a second portion 463. The dimension in the width direction (X) of the first portion 459 is defined as the dimension W3. The dimension in the width direction (X) of the second portion 463 is defined as the dimension W4. The dimension W3 is larger than the dimension W4.

The distance G1 of the holding portions 399 is larger than the dimension W3 of the first portion 459 of the auxiliary dust collector 450. Thereby, the holding portion 399 can arrange the first portion 459 between the pair of plate-shaped 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. As a result, the holding portion 399 can restrict the movement of the first portion 459 in the depth direction (Y). That is, it is possible to prevent or reduce the auxiliary dust collector 450 from being detached from the holding portion 399 in the depth direction (Y). 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. As a result, 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 sliding along the axial direction (Z). Each plate-shaped portion 401 of the holding portion 399 may be elastically deformable in the thickness direction (X) thereof. As a result, the auxiliary dust collector 450 can be attached and detached even by moving the auxiliary dust collector 450 in the depth direction (Y). In particular, the convex portion 405 has a tapered tip. This makes it possible to easily attach / detach the auxiliary dust collector 450 by moving it in the depth direction (Y).

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

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

The holding portion 399 may be provided on the vacuum cleaner main body 340 instead of the handle 390. Two holding portions 399 may be provided on both the handle 390 and the vacuum cleaner body 340, respectively. One holding portion 399 may straddle both the handle 390 and the vacuum cleaner body 340.

1-6. Auxiliary dust collector

The auxiliary dust collector 450 is a cleaning tool such as a mop, a dust remover, a brush, a broom, and a scrubbing brush. As shown in FIG. 8, the auxiliary dust collector 450 includes a head portion 451 and a handle portion 457. The head portion 451 includes a head main body 453 and mounting means (mounting button 455 as an example). The handle portion 457 includes a first portion 459 and a second portion 463.

The second portion 463 of the handle portion 457 has an engagement hole 467 for engaging the mounting button 455. The mounting button 455 is exposed to the outside of the second portion 463 through the engaging hole 467. The mounting button 455 is urged by a spring force to realize a strong engagement with the engaging hole 467. As an example, a U-shaped notch is formed in the plate portion, and the mounting button 455 is provided in the internal portion of the U-shape. The U-shaped internal portion can be elastically deformed in the plate thickness direction with respect to the other portion of the plate portion. This makes it possible to generate a spring force. When the mounting button 455 is pushed into the inside of the second portion 463 against the spring force, the engagement between the mounting button 455 and the engaging hole 467 can be released. As a result, the head body 453 and thus the head portion 451 can be removed from the second portion 463 and thus the handle portion 457. The head portion 451 may be detachably attached to the handle portion 457 by any other method. For example, the handle portion 457 and the head portion 451 may be attached by screws. Further, the head portion 451 may be detachably attached to the handle portion 457. For example, the head portion 451 may be integrally formed with the handle portion 457.

As shown in FIG. 9, the first portion 459 of the handle portion 457 has a tubular shape having a substantially quadrangular cross section. The first portion 459 has a ridge portion 461 protruding toward the internal space on a pair of side surfaces facing each other. The second portion 463 of the handle portion 457 has a tubular shape having a substantially quadrangular cross section, and is internally fitted into the first portion 459. The second portion 463 has a pair of side surfaces facing each other and a guide groove 469 that fits the ridge portion 461. As described above, the second portion 463 is slidably attached to the first portion 459. That is, the handle portion 457 can be expanded and contracted. As a result, the handle portion 457 can be contracted when the auxiliary dust collector 450 is accommodated in the accommodating portion 410, and the handle portion 457 can be expanded when the auxiliary dust collector 450 is used.

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

2. 2. Vacuum cleaner support device

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

2-1. Suction device mounting stand

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 mounting portion 511 has one or more (seven in the example shown in FIG. 10) communication ports 513 that communicate with the internal space 525. Each communication port 513 has a substantially quadrangular shape that is long in the depth direction (Y). The plurality of communication ports 513 are arranged in the width direction (X). These 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 mounted on the mounting portion 511. In other words, a communication port 513 is provided so that air and dust in the internal space 525 can be sucked when the switch of the vacuum cleaner 3 is turned on.
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 a plurality other than 7. However, when a plurality of small holes are used rather than one large hole, the flow velocity of the fluid passing through the holes can be increased, and the residual dust can be prevented or reduced.

The electric vacuum cleaner 3 can drive the electric blower while being supported by the vacuum cleaner support device 5. At this time, the vacuum cleaner 3 sucks the air and dust in the internal space 525 of the suction tool mounting table 510 through the communication port 513. On the other hand, the internal space 525 of the suction tool mounting table 510 can receive the head portion 451 of the auxiliary dust collector 450 through the insertion port 523. The dust adhering to the head portion 451 is sucked into the vacuum cleaner 3 through the communication port 513. As a result, 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 interior space 525. Each protrusion 515 is arranged between adjacent communication ports 513. For example, the auxiliary dust collector 450 is a mop having a large number 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 enters between the wings or fibers of the head portion 451 and scoops out the dust adhering to them. As a result, the head portion 451 can be cleaned more cleanly.

The plurality of protrusions 515 are arranged in parallel with each other. As a result, 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 slot 523 of the front surface portion 521 is defined as the dimension H5. The dimension in the width direction (X) of the insertion slot 523 is defined as the dimension W5. The area of the insertion slot 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) of the head portion 451 in the natural state is defined as the dimension H6. The dimension in the width direction (X) of the head portion 451 in the natural state is defined as the dimension W6. Here, the natural state means a state in which the head portion 451 is not subjected to the compressive force. The cross-sectional area of the head portion 451 is obtained by the product of the dimension H6 and the dimension W6. Preferably, the insertion slot 523 has an area smaller than the cross-sectional area of the head portion 451. As a result, the head portion 451 is filled in the entire insertion port 523. Air leakage due to insufficient filling of the insertion port 523 can be prevented or reduced, and therefore the suction force of the vacuum cleaner 3 can be effectively utilized.

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 the dimension L5. As shown in FIG. 10, the dimension of the head portion 451 in the insertion direction (Y) is defined as the dimension L6. The dimension L5 is smaller than the dimension L6. As a result, even if the head portion 451 is inserted all the way, the state in which the head portion 451 is filled in the entire insertion port 523 can be maintained. Therefore, the suction force of the vacuum cleaner 3 can be effectively utilized.
The suction tool mounting table 510 has a T-shape, and a support column 540 is erected on a stretched portion extending rearward. The internal space 525 is formed by utilizing this stretched portion as well. As a result, it is possible to sufficiently secure the dimension of the internal space 525 in the depth direction (Y) while forming the suction tool mounting table 510 in a slim manner. Further, since the stretched portion is in the center in the width direction (X), the balance of the support column 540 can be improved.

It should be noted that the influence of air leakage may not be present or may be small. In this case, the dimension L5 may be the same as or larger than the dimension L6. As a result, the head portion 451 can be cleaned as a whole.

As shown in FIG. 12, the suction tool mounting table 510 includes a positioning portion 527 in the mounting portion 511. The positioning unit 527 assists in arranging the suction tool 310 of the vacuum cleaner 3 in 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 a plurality of communication ports 513 of the mounting portion 511. The positioning portion 527 includes a first protruding piece 529 located at the front end of the mounting portion 511. The mounting portion 511 is inclined so that the rear end is higher than the front end thereof. The positioning portion 527 also serves as a stopper to prevent the suction tool 310 from rolling forward. The first projecting piece 529 abuts on the front end of the upper cover 311 of the suction tool 310 when the suction tool 310 is mounted on the mounting portion 511, 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 protruding pieces 531 located at the rear end of the communication port 513. Each second protruding piece 531 abuts on the inner wall 315 of the suction tool 310 when the suction tool 310 is mounted on the mounting portion 511, and moves in the depth direction (Y) and the width direction (X) of the suction tool 310. To regulate.

The first protruding piece 529 and the second protruding piece 531 are also members that increase the fluid impedance of the gap between the suction tool 310 and the mounting portion 511. As a result, air leakage through the gap between the suction tool 310 and the mounting portion 511 can be prevented or reduced, and as a result, the suction force of the vacuum cleaner 3 can be effectively utilized for cleaning the head portion 451.
The suction tool 310 has grooves 329 communicating with the suction port 323 on both side surfaces of the suction tool 310. Air can be sucked from the lateral direction through the groove 329. The second protruding piece 531 of the suction tool mounting table 510 may have a function of closing the groove 329. This makes it possible to prevent or reduce air leakage through the groove 329.

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

On the other hand, as shown in FIG. 11, each protruding portion 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. Therefore, the second blade portion 519 can scoop out more dust than the first blade portion 517.

In this way, since a large amount of dust is scraped out at the lower part of the second region 327, it is possible to prevent or reduce the amount of dust left behind in the internal space 525.
The shape of the protrusion 515 is not limited to the above shape, and may be a constant height from the front end to the rear end. Further, 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 unit 527 is not limited to the above configuration, and may be provided all around the circumference of the suction tool 310. Further, instead of the protruding piece protruding from the mounting portion 511, it may be a concave portion recessed from the mounting portion 511 that matches the shape of the suction tool 310.
Further, the insertion port 523 may be provided on the side surface portion instead of the front surface portion 521.

2-2. Prop

The stanchion 540 is arranged at the rear end of the suction device mounting table 510 as shown in FIG. The strut 540 has a tapered surface 541 and a concave surface 543 on the upper portion thereof. The tapered surface 541 fits the end surface 371 of the extended portion 363 of the vacuum cleaner body 340. The concave surface 543 fits the outer peripheral surface of the second cylindrical portion 373 of the vacuum cleaner main body 340. The vacuum cleaner body 340 is held by the tapered surface 541 and the concave surface 543 and is maintained in an upright position.

The stanchion 540 preferably includes a charging mechanism 545 that charges the battery of the vacuum cleaner 3. The charging mechanism 545 includes, for example, a circuit module 547 provided in the support column 540 and a connector receiving portion 549 provided in 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 source. The connector receiving portion 549 conforms to the connector 379 (see FIG. 5) provided in the vacuum cleaner main body 340, and electrically connects the circuit module 547 and the battery. The column 540 can charge the battery inside the vacuum cleaner body 340 while keeping the vacuum cleaner body 340 in an upright position. The vacuum cleaner 3 is designed to drive the electric blower when switched on, even while the battery is charging.

<Second embodiment>
As shown in FIG. 13, the vacuum cleaner unit 1001 according to the second embodiment includes the vacuum cleaner 1003 and the vacuum cleaner support device 1005.
The electric vacuum cleaner 1003 is a so-called stick-type vacuum cleaner including 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 those in the first embodiment.
Similar to the first embodiment, the vacuum cleaner 1003 includes an accommodating portion 410 for accommodating the auxiliary dust collector 450 so as to be able to be taken out from the handle 390 side. The accommodating portion 410 is attached to the vacuum cleaner main body 340. The vacuum cleaner 1003 is charged from the vacuum cleaner support device 1005.
The vacuum cleaner support device 1005 includes a suction tool mounting stand 1510 for mounting the suction tool 1310 of the vacuum cleaner 1003, and a support column 540 for supporting the vacuum cleaner main body 340 of the vacuum cleaner 3.
In the second embodiment, mainly a part of the suction tool 1310 of the vacuum cleaner 1003 and the suction tool mounting stand 1510 of the vacuum cleaner support device 1005 are different from the first embodiment. Therefore, these differences will be mainly described below. The same reference numerals are used for the same configurations as in the first embodiment, and the description of the configurations will be omitted.

1. 1. Suction tool The suction tool 1310 has a suction space 1312 inside which communicates with the outside through the suction port 1323 at the bottom, as shown in FIG. 14 (a). The suction space 1312 is connected (communicates) with the inside of the dust collecting pipe 1320 via the communication port 1317 of the inner wall 1315 constituting the space. The dust collecting pipe 1320 is detachably connected to (the internal space) of the second cylindrical portion 373 of the vacuum cleaner main body 340.

1-1. Suction port The suction port 1323 includes a first region 1325 and a second region 1327, and the suction space 1312 is a first space 1314 existing behind the first region 1325 and a second area behind the second region 1327. It has 2 spaces 1316.
The tip of the leader line of the first space 1314 is an arrow in order to distinguish it from the leader lines of the first region 1325, the rotating brush 319, the inner wall 1315, and the like. Similarly, the leader line of the second space 1316 has an arrow at its tip in order to distinguish it from the leader lines of the second region 1327 and the inner wall 1315 and the like.

As shown in FIG. 14A, the first space 1314 has a shape close to a long columnar shape in the width direction (X). The first space 1314 accommodates a rotating brush 319 that is long in the width direction (X) and has a rotation axis in the width direction.
The second space 1316 exists between the first space 1314 (rotating brush 319) and the communication port 1317. As a result, the dust scraped out by the rotating brush 319 goes from the second space 1316 to the communication port 1317.
That is, the suction tool 1310 has two spaces adjacent to each other in the depth direction (Y), one of which is the first space 1314 for accommodating the rotating brush 319, and the other is the second space for generating a swirling airflow. 1316.
The rotary brush 319 consists of one or a plurality of brushes provided on the axis of rotation, for example, in a spiral shape. As the brush, a plate-like body such as a rubber material may be used, or a plurality of fibrous bodies such as a resin may be used. When a fibrous body is used, static elimination fibers such as organic conductive fibers obtained by chemically bonding copper sulfide to acrylic fibers or nylon fibers may be used as all or part of the fibrous bodies.

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

As shown in FIG. 14, the communication port 1317 is provided so as to be located in the second space 1316 on the opposite side of the first space 1314. By configuring the cross-sectional shape of the second space 1316 and the position of the communication port 1317 as described above, a swirling airflow is likely to be generated in the second space 1316. Further, since the second space 1316 is partitioned by the first space 1314 and the partition wall 1315a, the rotation brush 319 does not prevent the generation of the swirling airflow. The end portion of the tapered portion 1316b in the width direction (X) communicates with the outside via 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 1316a in the second space 1316.

Between the first space 1314 and the second space 1316, there is an overhanging portion 1318 that overhangs the first space 1314 side. The overhanging portion 1318 here is composed of an overhanging member different from the bottom cover 1313 constituting the suction space 1312.
The partition wall 1315a that separates 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 chipped portion of the intermediate portion in the width direction (X) of the partition wall 1315a. ..

The overhanging portion 1318 is provided so as to be in contact with the rotating brush 319. As shown in FIG. 15, the overhanging portion 1318 overhangs in the direction opposite to the rotation direction of the rotating brush 319 (the direction of the arrow in the drawing). That is, when they come into contact with each other, they project in the direction in which the brush of the rotating brush 319 is raised. As a result, 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. As a result, excessive wear of the rotating brush 319 can be suppressed. The overhanging portion 1318 may be made of a material capable of eliminating static electricity to prevent the adsorption of dust due to static electricity.
The dust separated from the rotating brush 319 is sucked to the adjacent second space 1316 side, and then sucked from the communication port 1317 to the vacuum cleaner main body 340 via the dust collecting pipe 1320.

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

As shown in FIG. 14 (b), the overhanging portion 1318 faces the communication port 1317 with the second space 1316 interposed therebetween. As a result, the dust scraped off by the overhanging portion 1318 is efficiently sucked from the communication port 1317.
The lower end of the overhanging portion 1318 in the axial direction (Z) is configured so as not to reach the cleaning surface as shown in FIG. 16B and FIG. As a result, the dust scraped off by the overhanging portion 1318 efficiently moves to the second space 1316.
As shown in FIG. 16B, the overhanging portion 1318 is located on the side opposite to the cleaning surface from the lower end (the end on the cleaning surface side) of the end portion in the width direction (X) of the partition wall 1315a. .. That is, the lower end of the overhanging portion 1318 is higher than the lower end of the partition wall 1315a constituting the tapered portion 1316b of the second space 1316 when the cleaning surface is used as a reference. As a result, the airtightness at the tapered portion 1316b of the second space 1316 can be enhanced, and the swirling airflow from the end in the width direction (X) toward the communication port 1317 in the second space 1316 can be strengthened.
The lower end of the overhanging portion 1318 in the axial direction (Z) 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 has a communication side pipe 1322 arranged facing the second space 1316 and a main body side pipe arranged on the vacuum cleaner main body 340 side. 1324 and a connecting pipe 1326 that rotatably connects 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 rotation axes. To prepare for. The connecting pipe 1326 is composed of a connecting lower pipe 1328 and a connecting upper pipe 1330.
The upstream side opening of the communication side pipe 1322 is attached to the bottom cover 1313 in a fixed state of being fitted to the opening provided in the inner wall 1315 of the bottom cover 1313. When the communication side pipe 1322 is attached to the bottom cover 1313, the upstream 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 portion with the vacuum cleaner main body 340 side, and is also electrically connected for rotationally driving the rotary brush 319 by a drive portion (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 connecting pipe 1326 around the X axis. The dust collecting pipe 1320 has a deregulation structure that regulates the rotation of the connecting pipe 1326 with respect to the communication side pipe 1322 around the Y axis and cancels the rotation regulation.

(2) Communication-side pipe and connection pipe The connection between the communication-side pipe 1322 and the connection pipe 1326 is such that the cylindrical portion 1322a on the downstream side of the communication-side pipe 1322 is connected to the connection lower pipe 1328 as shown in FIG. It is fitted to the cylindrical fitting portion 1328a at the upstream end of the above, and in this state, it is fixed by the “C” -shaped fixture 1331.
Since the cylindrical portion 1322a here is inserted into the fitting portion 1328a, the cylindrical axis of the cylindrical portion 1322a becomes the Y axis which is the rotation axis, and the connecting pipe 1326 can rotate with respect to the communication side pipe 1322. In this state, the cylindrical portion 1322a comes off from the fitting portion 1328a.

The communication side pipe 1322 has a peripheral groove 1322b extending in the circumferential direction in the cylindrical portion 1322a, and the connecting pipe 1326 has through holes 1328b and 1328c in the fitting portion 1328a at a portion corresponding to the peripheral groove 1322b of the cylindrical portion 1322a (FIG. 18). See). The convex portions 1331a and 1331b of the "C" -shaped fixative 1331 insert through the through holes 1328b and 1328c of the connecting lower pipe 1328 and fit into the peripheral groove 1322b of the communication side pipe 1322. As a result, it is possible to prevent the connecting pipe 1326 (connecting lower pipe 1328) from coming off from the communication side pipe 1322.

It will be explained in detail.
The fitting portion 1328a of the connecting lower pipe 1328 has a groove 1328d extending in the circumferential direction for the fixture 1331, and through holes 1328b and 1328c are provided in the bottom wall of the groove 1328d. Specifically, the positions of the through holes 1328b and 1328c correspond to the positions of the convex portions 1331a and 1331b of the fixture 1331. The "C" -shaped fixative 1331 has an arc shape longer than a semicircle, the convex portion 1331a is substantially in the center of the arc, and the convex portions 1331b are at both ends of the arc. This makes it difficult for the fixative 1331 to come off the connecting lower pipe 1328. The fixative 1331 is fixed to the connecting pipe 1326 and does not rotate only by the fixative 1331.

As shown in FIG. 19, the deregulation structure is composed of an engaged portion 1322c provided on the communication side pipe 1322 and an engaging portion 1331c provided on the connecting pipe 1326 side (here, the fixture 1331). It is composed.
The engaged portion 1322c has a recessed portion 1322d which is on the side opposite to the side where the fixture 1331 is present and is recessed in a direction parallel to the cylinder axis. The engaging portion 1331c has a convex portion 1331d that is on the communication side pipe 1322 side and projects in a direction parallel to the cylinder axis. When the convex portion 1331d engages (fits) with the concave portion 1332d, the rotation of the connecting pipe 1326 with respect to the communication side pipe 1322 is restricted.
The concave portion 1322d and the convex portion 1331d have an arcuate appearance when viewed from a direction orthogonal to the engaging direction (FIG. 19 (c)). As a result, the rotation regulation can be smoothly released.

Looking at the deregulation structure from a direction orthogonal to the engaging direction ((c) in FIG. 19), the engaged portion 1322c is inclined as it moves away from the recessed portion 1322d in the circumferential direction and becomes farther from the fixture 1331. The portion 1322e is provided on both sides of the recessed portion 1322d. As a result, even if the engaging portion 1331c (convex portion 1331d) is located at a position (in a state where rotation is not regulated) away from the engaged portion 1322c in the circumferential direction, the convex portion 1331d is moved by the rotation on the connecting pipe 1326 side. Smoothly engages (fits) with the recessed portion 1322d.
As shown in FIGS. 19A and 19B, the engaged portion 1322c is provided on the outer cylindrical portion 1322f coaxial with the cylindrical portion 1322a, and is engaged with the connecting lower pipe 1328 during rotation. The engaged portion 1322c is located on the orbit of the portion 1331c.

The fixative 1331 has an engaging portion 1331c that can be elastically deformed in a direction parallel to the cylinder axis. Specifically, the fixture 1331 has a U-shaped portion 1331f that projects in an inverted "U" shape outward in the radial direction from the "C" -shaped main body portion 1331e, and is engaged with the U-shaped portion 1331f. A joint portion 1331c is provided.
As a result, when the connecting pipe 1326 rotates 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 convex portion 1331d is engaged with the concave portion 1322d or the concave portion. The engagement can be smoothly disengaged from 1322d.

Since the fixture 1331 regulates the communication side pipe 1322 from coming off from the connecting pipe 1326, it has a rigidity (thickness) that does not break even when a load is applied. However, by providing the engaging portion 1331c in the U-shaped portion 1331f having a space between the main body portion 1331e, the U-shaped portion 1331f is engaged in the engaging direction (here, the cylindrical portion 1322a of the communication side pipe 1322) with an appropriate load. It can be prevented from being elastically deformed (in a direction parallel to the cylinder axis direction), making it difficult to release the engagement state between the convex portion 1331d and the concave portion 1322d.
In this way, by adopting the structure of the U-shaped portion 1331f, by appropriately selecting the space between the main body portion 1331e and the U-shaped portion 1331f, the engagement condition or engagement between the convex portion 1331d and the concave portion 1322d is performed. You can adjust the degree of release. The portion where the convex portion 1331d is provided may have a shape other than the U-shaped portion 1331f, for example, an L-shaped portion, an O-shaped portion, or the like.

Further, a drive unit (not shown) for rotationally driving the rotary brush 319 is provided in the suction tool 1310. Generally, there is a communication side pipe 1322 or the like in the central portion of the suction tool 1310 in the width direction (X), and the drive unit is arranged in a state of being displaced from the center of the suction tool 1310 in the width direction to one side in the width direction. ing. Therefore, when the suction tool 1310 is lifted during use, a load is generated in which the communication side pipe 1322 side tries to rotate with respect to the connecting pipe 13326 due to the influence of the rotation moment due to the weight of the drive unit. By configuring the U-shaped portion 1331f so as not to be elastically deformed (the engaged state is not released) with respect to the load of this rotation, it is possible to eliminate wobbling when the suction tool 1310 is lifted.

2. 2. Vacuum cleaner support device The vacuum cleaner support device 1005 supports the electric vacuum cleaner 1003. The vacuum cleaner support device 1005 here is a charging station for charging the battery built in the vacuum cleaner 1003. As shown in FIG. 13, the vacuum cleaner support device 1005 includes a suction tool mounting stand 1510 for mounting the suction tool 1310 of the vacuum cleaner 1003, and a support column 540 for supporting the vacuum cleaner 3 (vacuum cleaner main body 340). The suction tool mounting table 1510 has a nozzle holding portion 1535 that holds a gap nozzle 1007 to be mounted in place of the suction tool 1310.

As shown in FIG. 20, the suction tool mounting table 1510 has a mounting portion 511 on which the suction tool 1310 is mounted, a front surface portion 521 connected to the mounting portion 511, and a base portion 1530 facing the installation surface. The suction tool mounting table 1510 is located below the mounting section 511, that is, between the mounting section 511 and the base section 1530, and the front portion of the suction tool mounting table 1510 is located in front of the suction device mounting table 1510 via an insertion port 523 capable of receiving the head portion 451 of the auxiliary dust collector 450. It has an open internal space 525. The mounting portion 511 has a plurality of communication ports 513 communicating with the internal space 525 along the axial direction of the rotating brush 319. The mounting portion 511 is provided with a first protruding piece 529 as a positioning portion of the suction tool 1310 in the mounting portion 511.

The base portion 1530 has a recessed portion 1533 recessed in the installation surface side on the surface on the mounting portion 511 side, and a static elimination member, here, an iron plate 1534, is arranged in the recessed portion 1533. The base portion 1530 has a guide portion 1538 so that the head portion 451 of the auxiliary dust collector 450 can be smoothly inserted into the insertion port 523. The guide portion 1538 is composed of an inclined surface that descends forward.
The iron plate 1534 has a function of removing electric charges charged in the head portion 451 of the auxiliary dust collector 450. The iron plate 1534 is arranged 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 width direction (X) of the insertion port 523 and extends to the side opposite to the internal space 525 from the side wall 525a forming the internal space 525. This eliminates the need for a special configuration for fixing the iron plate 1534, and can be easily implemented.

The suction tool mounting table 1510 has a nozzle holding portion 1535 behind the mounting unit 511 when the suction device mounting table 1510 is viewed from above. The nozzle holding portion 1535 here is composed of an overhanging portion 1536 protruding from the base portion 1530 and a tubular portion 1537 extending upward from the overhanging portion 1536. The gap nozzle 1007 is detachably supported by fitting the tubular portion 1071 to the outside of the tubular portion 1537.
The overhanging portion 1536 is in a rectangular region having two sides, the dimension in the width direction (X) in the mounting portion 511 or the base portion 1530, and the dimension in the depth direction (Y) including the mounting portion 511 and the support column 540. It is provided so that it fits in. As a result, the gap nozzle 1007 can be held without substantially increasing the installation area of the vacuum cleaner support device 1005.

<Third embodiment>
In the first embodiment, the handle portion 457 of the auxiliary dust collector 450 is held so as to be sandwiched by the pair of plate-shaped portions 401 of the vacuum cleaner 3.
However, in the third embodiment, the auxiliary dust collector 2450 is held by the vacuum cleaner 2003 by utilizing the engaging structure. Hereinafter, the holding portion of the vacuum cleaner 2003 and the auxiliary dust collector 2450 will be described.

As shown in FIG. 21, the vacuum cleaner 2003 has a holding portion for holding the auxiliary dust collector 2450. The holding portion here is composed of an engaging portion 2399 that engages with the engaged portion 2458 of the handle portion 2457 of the auxiliary dust collector 2450.
The engaging relationship may be such that the engaged portion of the electric vacuum cleaner is engaged by the engaging portion of the handle portion of the auxiliary dust collector.

Here, the engaged portion 2458 of the auxiliary dust collector 2450 is composed of an inverted U-shaped plate portion 2458a extending in an inverted "U" shape from the end portion of the handle portion 2457 opposite to the head portion (451). The engaging portion 2399 is composed of an L-shaped plate portion 2399a extending in an "L" shape on the side opposite to the head portion (451) of the auxiliary dust collector 2450.
The L-shaped plate portion 2399a passes through the through hole 2460 formed by the inverted U-shaped plate portion 2458a and the end surface 2457a of the handle portion 2457 and engages with the handle portion 2457 of the auxiliary dust collector 2450. Supported by the vacuum cleaner 2003.

As shown in the enlarged view, the engaging portion 2399 has a convex region 2399b protruding inward at the tip end portion of the L-shaped plate portion 2399a. This prevents the inverted U-shaped plate portion 2458a from coming off the L-shaped plate portion 2399a.
The engaging portion may have a groove in which the L-shaped plate portion is fitted (tightly fitted) instead of the convex region 2399b.

The vacuum cleaner 2003 here has a convex portion 2392 protruding to the back side in the handle portion 2390. As a result, it is possible to reduce the possibility that the handle portion 1390 slips from the user's hand when the vacuum cleaner 2003 is used.

As shown in FIG. 22, the handle portion 2457 of the auxiliary dust collector 2450 includes a cylindrical first portion 2459 and a tubular second portion 2463, as in the first embodiment. The second portion 2463 is inserted inside the first portion 2459 and is configured to be stretchable with respect to the first portion 2459.
The first portion 2459 has through holes 2459a and 2459b on both sides in the longitudinal direction. The second portion 2464 has an operation button 2464 projecting outward from the through hole 2463a on the side opposite to the head portion (451) in the longitudinal direction.
The operation button 2464 has a button portion 2466 and a button portion that are fitted into the through holes 2459a and 2459b of the first portion 2459 and are supported so as to appear and disappear in the thickness direction (inner and outer directions) of the first portion 2459 and the second portion 2463. It has an elastic spring 2468 that urges the 2466 in the inward and outward directions of the through hole 2464a.

When accommodating the auxiliary dust collector 2450 in the accommodating portion 410 of the vacuum cleaner 2003, the second portion 2463 is inserted into the first portion 2459, and the button portion 2466 is fitted into the through hole 2459a of the first portion 2459. Let me. As a result, the contracted state can be maintained and it can be accommodated compactly.
When using the auxiliary dust collector 2450, the button portion 2466 is pushed inside the first portion 2459 to release the fitting state of the button portion 2466 into the through hole 2459a. Then, the second portion 2463 is pulled out from the first portion 2459, and the button portion 2466 is fitted into the through hole 2459b of the first portion 2459. As a result, the second portion 2463 can be used in a long state pulled out from the first portion 2459.
Although two through holes 2459a and 2459b of the first portion 2459 are provided on both sides in the longitudinal direction, three or more through holes may be provided at intervals in the longitudinal direction. This enables finer length adjustment.

Although the embodiment has been described above, the embodiment is not limited to this embodiment, and for example, the following modification may be used. Further, the embodiment, the modified example, and the modified example may be combined.
Further, the present invention includes examples not described in the embodiments and modifications, and design changes within a range not deviating from the gist.

<Modification example>

The present invention is not limited to this, and may include only one of them.

(2) In the above embodiment, the vacuum cleaner support device 5 includes a charging mechanism 545, but the present invention is not limited to this. The vacuum cleaner support device 5 does not have to include the charging mechanism 545.
In the above embodiment, the vacuum cleaner 3 is a vacuum cleaner to which a power cord is not attached, but the present invention is not limited to this. It may be a vacuum cleaner with a power cord.

(3) Although the head main body 453 of the auxiliary dust collector 450 is not particularly described in the above embodiment, when a fibrous body such as a mop or a brush is used as the head main body, a polypropylene split is used. It is preferable to use yarn. By using this, it is easy to catch dust, etc., and when the head body is inserted into the internal space 525 of the suction tool mounting tables 510, 1510 and sucked by the vacuum cleaner 3,1003, the fibrous form of dust. Good release from the body.
That is, the fibrous body of the head body inserted in the internal space 525 can absorb dust from the head body without being entangled with the rotating brush (nylon fiber) of the vacuum cleaner.

(4) The deregulation structure is not limited to the contents described in the second embodiment, and focusing on the deregulation structure, the type of vacuum cleaner (stick type, canister type), auxiliary dust collector and accommodating portion. It does not matter whether or not there is a vacuum cleaner, whether or not there is a vacuum cleaner support device, and whether or not there is a second space.
The deregulation structure is such that the first pipe side (one example is the first pipe or the peripheral member of the first pipe which is the communication side pipe) is opposed to the second pipe side (one example is the second pipe or the second pipe which is a connecting pipe). In the case of rotatably connecting (which is a peripheral member of 2 pipes), the 2nd pipe side has an engaging portion that engages with the engaged portion on the 1st pipe side to regulate the rotation with respect to the 1st pipe. However, at least one of the engaged portion and the engaged portion is configured to be elastically deformable when the second pipe tries to rotate with respect to the first pipe. As a result, the engagement relationship can be easily released and restored.
In the second embodiment, the fixture 1331 (an example of a peripheral member) fixed to the second pipe is provided with the engaging portion 1331c, but even if the connecting pipe 1326 is provided with the engaging portion. good. That is, it suffices if the member that rotates integrally with the second pipe has an 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 attached to the bottom cover (which is an example of the peripheral member) to which the first pipe is mounted. Alternatively, an engaging portion may be provided, or an engaged portion or an engaging portion may be provided on the upper cover (an example of a peripheral member).

In the second embodiment, the engaging portion 1331c of the fixture 1331 is configured to be elastically deformable, but the engaged portion on the first pipe side may be configured to be elastically deformable or engaged. The portion and the engaging portion may be configured to be elastically deformable.
In the second embodiment, the engaging portion 1331c is composed of a convex portion 1331d protruding in a direction parallel to the rotation axis of rotation with respect to the first pipe, and the engaged portion 1322c is recessed in a direction parallel to the rotation axis. It is composed of a recessed portion 1322d. However, the relationship between the engaged portion and the engaged portion may be reversed. That is, the engaging portion of the convex portion may be on the first pipe side, and the engaged portion of the concave portion may be on the second pipe side.
Further, although the convex portion and the concave portion are provided parallel to the rotation axis, they may be provided outward or inward in the direction orthogonal to the rotation axis.
In the second embodiment, the U-shaped portion 1331f provided with the convex portion 1331d in the fixture 1331 is elastically deformable, but the convex portion can be elastically deformed by forming the convex portion with, for example, a thin piece. It may be configured as.

(5) The suction tools 310 and 1310 of the first and second embodiments include a space for accommodating the rotating brush 319 (first space) and a space capable of generating a swirling airflow (second space). However, the suction tool has a first space (1314) for accommodating the rotating brush 319 and a second space (1316) parallel to the rotation axis of the rotating brush 319 and adjacent to the first space (1314). The second space may be a space having a structure in which a swirling airflow does not occur.
The second space 1316 is in a direction parallel to the rotation axis of the rotation brush 319, and both side portions thereof are tapered portions 1316b, but the second space 1316 does not have to be tapered. Although a swirling airflow is generated even if both side portions are not tapered, a stronger swirling airflow can be obtained by making the tapered shape.
The positional relationship between the first space and the second space before and after is not particularly limited. However, in the first regions 325 and 1325 of the suction ports 323 and 1323, it is preferable that the second space exists on the downstream side in the rotation direction of the rotary brush 319.

In the second embodiment, the overhanging portion 1318 is provided between the first space 1314 and the second space 1316, and the degree of sealing between the tapered portion 1316b and the cleaning surface of the tapered portion 1316b in the second space 1316 is the straight portion 1316a. Although the degree of sealing with the cleaning surface is higher than the degree of sealing, the degree of sealing of the tapered portion 1316b may be the same as the degree of sealing of the straight portion 1316a, or may be lower than the degree of sealing of the straight portion 1316a. However, when it is desired to use a strong swirling airflow, it is better to make the degree of sealing of the tapered portion 1316b higher than the degree of sealing of the straight portion 1316a.
Focusing on the swirling airflow, it does not matter what type of vacuum cleaner (stick type, canister type), whether or not there is an auxiliary dust collector or accommodating part, and whether or not there is a vacuum cleaner support device.
