< first embodiment >

1. Electric vacuum cleaner

As shown in fig. 1, the electric vacuum cleaner apparatus 1 includes an electric vacuum cleaner 3 and a cleaner support device 5. The electric vacuum cleaner 3 includes a suction tool 310, a cleaner main body 340, and a handle tool 390 in this order, and is a so-called stick-type vacuum cleaner. The electric vacuum cleaner 3 includes a housing 410 for housing the auxiliary dust collecting member 450 so as to be freely taken out from the handle member 390 side. The storage 410 is attached to the cleaner main body 340. The electric vacuum cleaner 3 is a portable type charged from the cleaner support device 5.

Here, the direction in which the suction tool 310, the cleaner body 340, and the grip piece 390 are sequentially arranged in the electric vacuum cleaner 3 is referred to as an axial direction Z, the direction in which the suction port 323 of the suction tool 310 (the rotation axis of the rotary brush 319) extends is referred to as a width direction X, and the direction orthogonal to the axial direction and the width direction (the direction in which the rotary brush 319 travels) is referred to as a depth direction Y.

1-1. Vacuum cleaner main body

The cleaner main 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 enlarged portion 363 is located between the first cylindrical portion 343 and the second cylindrical portion 373, having a common central axis with 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 enlarged portion 363 has an outer diameter larger than each of the outer diameters of the first cylindrical portion 343 and the second cylindrical portion 373. Thus, the cleaner main body 340 has an enlarged portion 363 having a large outer peripheral dimension in the middle of the movement from the handle member 390 side to the suction member 310 side. The enlarged portion 363 has not only the outer peripheral surface 365 but also an end surface 369 on the handle member 390 side connected to the first cylindrical portion 343 and an end surface 371 on the suction member side connected to the second cylindrical portion 373. The end surfaces 369 and 371 are tapered.

The shape of the cleaner main body 340 is not limited to this, and may have a predetermined outer diameter from the grip piece 390 side to the suction piece 310 side, or may have a reduced portion with a small outer diameter in the middle of the movement from the grip piece 390 side to the suction piece 310 side. The shape of the cleaner main body 340 is not limited to a cylindrical shape, and may be, for example, a cylindrical shape having a polygonal cross section such as a triangular cross section, a quadrangular cross section, a hexagonal cross section, or an octagonal cross section, or a combination thereof, or may be a cylindrical shape having an asymmetric cross section.

The cleaner main body 340 includes, for example, an electric blower, a battery, a circuit module, a dust collection unit mounting portion, and an indicator 377. These components are housed in the cylindrical housing 341. For example, the first cylindrical portion 343 houses a battery, a circuit module, and an indicator 377. The enlarged portion 363 houses an electric blower. The second cylindrical portion 373 houses the dust collecting assembly mounting portion and the dust collecting assembly. The battery stores electric power received from the commercial power supply via the circuit module. The battery supplies the stored electric power to the electric blower via the circuit module. The electric blower generates a negative pressure for sucking dust. The dust collecting component mounting part is detachably mounted with a dust collecting component for accumulating the sucked 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 displays various information such as the remaining battery level, the operation mode, and the filling rate of the dust collecting unit. The first cylindrical portion 343 has an elliptical window 351 in its outer peripheral surface 349. The indicator 377 is configured to be externally visually recognizable through the elliptical window 351. The indicator 377 may have not only a display function but also an operation function. The operation function is, for example, an ON/OFF button. Thus, even when the handle member 390 is removed, the electric vacuum cleaner 3 can be operated.

The cleaner main body 340 has a mounting unit for detachably mounting the handle member 390. An engaging portion as an example of the attachment means is not shown in fig. 1 because it is fitted into the grip member 390. The convex engaging portion on the handle member 390 side is engaged with the concave engaging portion on the cleaner body 340 side by operating the attachment button 375 on the handle member 390 side. The mounting unit is not limited thereto, and may be a screw.

The cleaner main body 340 has an attachment structure for detachably attaching the storage section 410. This will be described in detail later.

1-2. Handle piece

The handle 390 includes a cylindrical housing 391, and the cylindrical housing 391 has 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 attachment button 375 is exposed to the outside of the cylindrical housing 391 through a through hole 395. When the attachment button 375 is pressed into the cylindrical housing 391, the engagement between the engaging concave portion and the engaging convex portion can be released. This allows the cylindrical housing 391 and, hence, the handle 390 to be taken out of the cleaner main body 340. The handle member 390 may be detachably attached to the cleaner main body 340 by other methods. The handle member 390 may be detachably attached to the cleaner main body 340. For example, the handle member 390 may be integrally formed with the cleaner main body 340.

The outer shape of the grip piece 390 is not limited to a cylindrical shape, and may be, for example, a cylindrical shape having a polygonal cross section such as a triangular cross section, a quadrangular cross section, a hexagonal cross section, or an octagonal cross section, or a combination thereof, or a cylindrical shape having an asymmetric shape.

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

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

The handle 390 has a holding portion 399 for holding the auxiliary dust collecting member 450 accommodated in the accommodating portion 410. This will be described in detail later.

1-3. Inhalation piece

As shown in fig. 2, the suction member 310 has a suction port 323 at the bottom thereof. The suction port 323 accommodates a rotary brush 319 therein.

The suction member 310 has a dust collecting duct therein, which connects the second cylindrical portion 373 of the cleaner body 340 and the suction port 323 of the suction member 310. The inner wall 315 has a communication port 317 connected to the dust collection conduit. The dust sucked from the suction port 323 is transported to the dust collection unit housed in the second cylindrical portion 373 through the communication port 317 and the dust collection duct.

The suction unit 310 includes three rollers 321 on a bottom cover 313. This allows the suction tool 310 to smoothly move on a surface to be cleaned, such as a bed.

1-4. Storage part

As shown in fig. 1, the receiving part 410 has an opening 433 for receiving the auxiliary dust collecting member 450. The auxiliary dust collector 450 is freely taken out from the handle 390 side and is received in the receiving portion 410. More specifically, the housing 410 is formed in a bottomed tubular shape with an opening 433 facing the handle 390 side. Thereby, the auxiliary dust collector 450 can be easily taken out during the use of the electric vacuum cleaner 3. As described above, the electric vacuum cleaner 3 incorporates a battery for driving the electric blower. Therefore, the electric vacuum cleaner 3 has strong mobility. The electric vacuum cleaner 3 having such a high mobility includes the housing 410 for housing the auxiliary dust collector 450. Therefore, the auxiliary dust collector 450 can be used to clean the vacuum cleaner 3 without impairing the strength of the flexibility of the auxiliary dust collector 450.

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

The first side portion 411 and the second side portion 415 are substantially parallel. The first side surface portion 411 has two longitudinal protruding pieces 413 on a surface opposite to the second side surface portion 415. The "vertical" here means a direction along the cylinder axis of the housing 410. The two projecting pieces 413 are respectively disposed at two upper and lower positions of the opposing surfaces. Although not shown in fig. 3, similarly, the second side surface portion 415 has two longitudinal protruding pieces 413 on the surface opposite to the first side surface portion 411. When the housing 410 is viewed from the front, the protruding piece 413 has a rectangular shape that is long. The four protruding pieces 413 are provided at positions near four corners of the housing portion 410, respectively. Thereby, the receiving portion 410 can be firmly fixed to the first cylindrical portion 343. The shape and position of the protruding piece 413 are not limited to these, and an engaging portion may be provided on one side and an engaged portion may be provided on the other side so that the front surface portion 425 and the first cylindrical portion 343 are attached to face each other. For example, the protruding piece 413 may protrude from the front surface 425 in an L shape.

The front surface 425 has a concave shape that fits the outer peripheral surface 349 of the first cylindrical portion 343 of the cleaner main body 340. The front portion 425 has two elongated protrusions 427 and one elongated engagement projection 429. The "horizontal" here means a direction (circumferential direction) perpendicular to the cylindrical axis of the housing 410.

The back face portion 419 has a parallel portion 421 substantially parallel to the front face portion 425 and an inclined portion 423 inclined to the front face portion 425. The inclined portion 423 serves to enlarge the area of the opening 433. That is, the inclined portion 423 is inclined in such a manner that the opening side is expanded. The head 451 of the auxiliary dust collector 450 can be easily inserted into the receiving portion 410 by enlarging the area of the opening 433. Also, when the auxiliary dust collector 450 is taken out of the receiving part 410, the handle part 457 can be inclined to be separated from the handle part 390. The inclined portion 423 serves to gradually reduce the inner space of the receiving portion 410 from the opening 433 toward the bottom surface portion 431. Thereby, the head 451 of the auxiliary dust collector 450 can be smoothly moved from the opening 433 to the bottom portion 431. The back face portion 419 is not limited to this, and may be formed so that the entire face is substantially parallel to the front face portion 425. Further, instead of or in addition to the inclination of the back face portion 419, the first side face portion 411 and/or the second side face portion 415 may be inclined so as to widen from the bottom face portion 431 side toward the opening 433 side, and in this case, may be inclined so as to gradually widen from the bottom face portion 431 to the middle and to widen from the middle to the opening 433 side by a larger width than before.

As shown in fig. 3, the first cylindrical portion 343 of the cleaner main body 340 has four longitudinal guide grooves 353 in the outer peripheral surface 349 thereof. The "longitudinal" here is a direction along the cylinder axis of the first cylindrical portion 343. The four guide grooves 353 receive the four protruding pieces 413 of the receiving portion 410, respectively, and guide the receiving portion 410 to an appropriate position.

The first cylindrical portion 343 has four elongated projections 355 on the outer peripheral surface 349 thereof. The four protruding pieces 355 can engage with the four protruding pieces 413 of the housing 410 disposed on the flanks of the four guide grooves 353 and further toward the rear. Specifically, when the projection piece 355 is engaged with the projection piece 413, the front surface of the projection piece 355 abuts against the rear surface of the projection piece 413. When the housing 410 (the protruding piece 413) slides along the guide groove 353 to the lower end of the guide groove 353, the four protruding pieces 413 of the housing 410 engage with the four protruding pieces 355 of the first cylindrical portion 343, respectively. This restricts the movement of the housing portion 410 in a direction other than the cylinder axis direction of the first cylindrical portion 343.

In a state where the housing 410 is attached to the first cylindrical portion 343, the tips of the first side surface 411 and the second side surface 415 are close to the outer peripheral surface 349 of the first cylindrical portion 343. Therefore, dust can be prevented from entering between the housing 410 and the first cylindrical portion 343. And the accommodation portion 410 and the first cylindrical portion 343 are integrally sensed.

Thus, the housing 410 is detachably attached to the first cylindrical portion 343 and further to the cleaner main body 340. Therefore, the storage section 410 can be taken out from the cleaner body 340 and the storage section 410 can be cleaned.

The first cylindrical portion 343 has a laterally long engaging recess 357 on its outer peripheral surface 349. The "lateral" referred to herein is a direction (circumferential direction) perpendicular to the cylinder axis of the first cylindrical portion 343. The engaging concave portion 357 can engage with the engaging convex portion 429 of the receiving portion 410. When the receiving portion 410 (the protruding piece 413) slides along the guide groove 353 to the lower end of the guide groove 353, the engaging convex portion 429 engages with (fits into) the engaging concave portion 357. This can restrict the movement of the first cylindrical portion 343 of the housing 410 in the cylinder axis direction. However, the engagement between the engaging convex portion 429 and the engaging concave portion 357 is designed to be relatively gentle. Therefore, the engagement between the engaging convex portion 429 and the engaging concave portion 357 can be released by the purposefully forced sliding of the receiving portion 410. This enables the storage unit 410 to be attached to and detached from the first cylindrical portion 343, and prevents or reduces unintended detachment of the storage unit 410 from the first cylindrical portion 343.

As described above, the front surface 425 of the housing 410 has the vertically long protruding portion 427. These protrusions 427 form gaps between the front surface portion 425 of the receiving portion 410 and the outer peripheral surface 349 of the first cylindrical portion 343. The receiving portion 410 is not in contact with the front face portion 425 but is in contact with the first cylindrical portion 343 via the protruding portion 427. This reduces the contact area of the housing 410 with the first cylindrical portion 343, and as a result, the housing 410 can slide smoothly on the first cylindrical portion 343.

As shown in fig. 4, the receiving portion 410 is attached to the first cylindrical portion 343. The bottom 431 of the storage 410 is along an end 369 of the enlarged 363 of the cleaner body 340 on the side of the handle 390. This can provide a feeling of unity between the storage portion 410 and the cleaner body 340.

As shown in fig. 4, a dimension in the depth direction Y between the back side 419 of the storage 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 peripheral 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 center axis C of the cleaner body 340 is defined as a dimension L3. Dimension L1 is the same as or larger than dimension L2. Further, dimension L1 and dimension L3 are the same or larger than each other. That is, the dimension of the cleaner main body 340 perpendicular to the center axis C, that is, the dimension L1 in the depth direction Y from the mounting portion of the housing 410 on the outer peripheral surface 349 with respect to the center axis C is equal to or larger than the dimension L2 of the enlarged portion 363. In other words, the storage 410 may be flush with or protrude from the enlarged portion 363 of the cleaner body 340 in the depth direction Y.

Further, the center axis C of the first cylindrical portion 343 is offset from the center axis C of the enlarged portion 363, and thereby the housing 410 is flush with or drawn into the enlarged portion 363 in the depth direction Y.

The wiring cover 367 internally houses wiring for connecting a connector 379 (see fig. 5) and the battery in the first cylindrical portion 343. Although the wiring cover 367 is exposed outside the enlarged portion 363, it is not limited thereto. For example, the wiring cover 367 may be housed inside the enlarged portion 363.

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

When the depth direction dimension and the width direction dimension satisfy the above-described relationship, the storage section 410 and the cleaner body 340 can be integrally sensed, and as a result, the design can be improved. Further, the storage 410 may be drawn in the depth direction Y with respect to the enlarged portion 363 of the cleaner body 340.

Preferably, the receiving part 410 is made of a material that can be washed with water. The housing 410 can be kept clean by appropriate water washing of the housing 410. Water washable is chemically stable with respect to water. For example, resins such as polypropylene, polycarbonate, and polyethylene terephthalate, metals such as steel, aluminum alloy, and stainless steel, or non-metals such as ceramics can be used.

As described above, the receiving portion 410 can be taken out from the first cylindrical portion 343. However, the present invention is not limited thereto. For example, the receiving portion 410 may be formed integrally with a part of the rear surface portion of the first cylindrical portion 343, and the receiving portion 410 may be taken out from the front surface portion of the first cylindrical portion 343 at the same time as the part of the rear surface portion.

As described above, the storage section 410 is detachably attached to the cleaner main body 340. However, the storage section 410 is not limited thereto, and may be non-detachably attached to the cleaner main body 340. The receiving portion 410 may be formed integrally with the cleaner body 340.

The detachable attachment structure is not limited to the above structure. For example, a coupling mechanism such as a combination of a nut and a bolt may also be employed. Magnetic means such as a permanent magnet and a magnetic metal may be used. Also, a suction mechanism such as a suction cup may be employed.

The receiving portion 410 may have one or more holes in the bottom portion 431. This prevents or reduces accumulation of dust in the internal space of the housing 410. Conversely, the bottom 431 having no hole may be used for the storage section 410. This prevents dust from leaking out of the internal space of the housing 410.

1-5. Holding part

As shown in fig. 1, the holding portion 399 is provided to the handle member 390. The holding part 399 holds the auxiliary dust collecting member 450 received in the receiving part 410. In detail, the holding portion 399 is located near the cleaner main body 340 of the handle member 390. As described above, the cleaner main body 340 has the step portion 359 on the handle member 390 side. Since the holding portion 399 is located near the stepped portion 359, it is possible to prevent an object from being caught on the holding portion 399. Further, it is difficult for the user to get the auxiliary dust collector 450 out of the receiving part 410 while holding the handle 457 of the auxiliary dust collector 450.

Specifically, 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 in which the suction tool 310, the cleaner body 340, and the grip piece 390 are arranged (Z: axial direction). Each plate-like portion 401 has a rectangular shape that grows in the axial direction Z. Thereby, the handle 457 of the auxiliary dust collecting member 450 can be firmly held. The front end of each plate-like portion 401 in the depth direction Y may not protrude beyond the outer peripheral surface 349 of the first cylindrical portion 343. Thus, when the housing portion 410 is slid for attachment and detachment of the housing portion 410, interference of the respective plate-like portions 401 with the housing portion 410 can be prevented. Each plate-like portion 401 has opposing faces 403 opposing each other. Thus, when the shank 457 of the auxiliary dust collector 450 is placed between the opposing surfaces 403, the movement of the shank 457 in the width direction X can be restricted. The holding portion 399 includes a pair of vertically long protrusions 405. The convex portions 405 protrude from the opposing surfaces 403 of the plate-like portion 401 toward each other. Each convex portion 405 is provided at the distal end portion of the plate-like portion 401 in the depth direction Y.

As shown in fig. 7, the holding part 399 holds the auxiliary dust collecting member 450, more specifically, the handle 457 of the auxiliary dust collecting member 450. The handle 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 a dimension W3. The dimension of the second portion 463 in the width direction X is defined as a dimension W4. Dimension W3 is greater than dimension W4.

The interval G1 of the holders 399 is greater than the dimension W3 of the first section 459 of the auxiliary dust collection member 450. Thus, the holding portion 399 can dispose the first portion 459 between the pair of plate-like portions 401. The interval G2 of the holders 399 is smaller than the dimension W3 of the first section 459 of the auxiliary dust collection member 450. Thus, holding portion 399 can restrict movement of first portion 459 in depth direction Y. That is, the auxiliary dust collector 450 can be prevented or reduced from being detached from the holding part 399 in the depth direction Y. The interval G2 of the holders 399 is greater than the dimension W4 of the second section 463 of the auxiliary dust collecting member 450. Thus, the curved 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 in 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 even by moving the auxiliary dust collector 450 in the depth direction Y. Specifically, the convex portion 405 has a tapered shape at its tip. This allows easy attachment and detachment by moving the auxiliary dust collector 450 in the depth direction Y.

The holder 399 can prevent the auxiliary dust collector 450 from being shaken during cleaning. Further, the holding part 399 can prevent the auxiliary dust collecting member 450 from being lost when the electric vacuum cleaner 3 is stored.

The holding unit 399 is not limited to the above configuration as long as it can detachably hold the auxiliary dust collector 450. For example, a coupling mechanism such as a combination of a nut and a bolt may also be employed. Magnetic means such as a permanent magnet and a magnetic metal may be used. Also, a suction mechanism such as a suction cup may be employed.

The shape of each plate-like portion 401 is not limited to a rectangular shape as long as it has a predetermined length in the axial direction Z. For example, the shape may be a semicircular shape, a trapezoidal shape, or a triangular shape. In the case of the trapezoidal shape and the triangular shape, the depth direction Y may be made larger from the upper end to the lower end, or vice versa.

The holding portion 399 may be provided not only to the handle member 390 but also to the cleaner main body 340. The two holding portions 399 are also provided in both the handle member 390 and the cleaner main body 340, respectively. One retaining portion 399 may also span both the handle member 390 and the cleaner body 340.

1-6. Auxiliary dust collecting member

The auxiliary dust collecting member 450 is a cleaning tool such as a mop, a dust brush, a broom, and a brush. As shown in fig. 8, the auxiliary dust collecting member 450 includes a head 451 and a handle 457. The head 451 includes a head body 453 and an attachment mechanism (an attachment button 455, for example). The handle 457 is provided with a first portion 459 and a second portion 463.

The second portion 463 of the handle 457 has a snap aperture 467 for snap fitting the mounting button 455. The attachment button 455 is exposed to the outside of the second portion 463 through the engagement hole 467. The mounting button 455 is urged by a spring force to be firmly engaged with the engaging hole 467. For example, a U-shaped cutout is formed in the plate portion, and the attachment button 455 is provided in an inner portion of the U-shape. The inner portion of the U-shape is elastically deformable in the plate thickness direction with respect to the other portions of the plate portion. Whereby a spring force can be generated. When the attachment button 455 is pushed into the second portion 463 against the spring force, the engagement between the attachment button 455 and the engagement hole 467 can be released. Thereby, the head body 453 and the head 451 can be taken out from the second portion 463 and the handle 457. The head 451 may be detachably attached to the shank 457 by other methods. For example, the shank 457 and the head 451 are also mounted by screws. The head 451 may be detachably attached to the shank 457. For example, the head 451 may also be integrally formed with the handle 457.

As shown in fig. 9, the first portion 459 of the shank 457 has a cylindrical shape having a substantially quadrangular cross section. The first section 459 has protrusions 461 protruding toward the internal space on a pair of side surfaces facing each other. The second portion 463 of the shank 457 has a cylindrical shape with a substantially quadrangular cross section and is fitted into the first portion 459. The second section 463 has guide grooves 469 fitted to the protrusions 461 on a pair of sides facing each other. In this way, the second portion 463 is slidably mounted with respect to the first portion 459. That is, handle 457 is telescopic. Thus, the handle 457 can be contracted when the auxiliary dust collector 450 is accommodated in the accommodating portion 410, and the handle 457 can be extended when the auxiliary dust collector 450 is used.

As shown in fig. 7, the shank 457 has a curved portion 465. Also, as described above, the first cylindrical portion 343 of the cleaner main body 340 has the stepped portion 359 formed by the conical surface 347 and the upper surface 345. The auxiliary dust collecting member 450 is received in the receiving part 410 and held in the holding part 399, and the bent portion 465 follows the stepped portion 359. This can provide a sense of unity in design.

2. Dust collector supporting device

As shown in fig. 1, the electric vacuum cleaner apparatus 1 includes an electric vacuum cleaner 3 and a cleaner support device 5. The cleaner support device 5 supports the electric cleaner 3. The cleaner support device 5 here is a charging station that charges a battery incorporated in the electric cleaner 3. The cleaner support device 5 includes a suction tool mounting base 510 on which the suction tool 310 of the electric cleaner 3 is mounted, and a support 540 that supports the cleaner main body 340 of the electric cleaner 3.

2-1. Suction piece placing table

As shown in fig. 10, the suction mount table 510 includes a mounting portion 511 on which the suction unit 310 is mounted, and a front surface portion 521 continuous with the mounting portion 511. The suction table 510 has an internal space 525 below the placement portion 511. The front surface 521 has an insertion port 523 communicating with the internal space 525. The insertion port 523 can receive the head 451 of the auxiliary dust collecting member 450. The placement 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 of the communication ports 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. When the suction tool 310 of the electric vacuum cleaner 3 is appropriately placed on the placement portion 511, the communication port 513 faces the suction port 323 at the bottom of the suction tool 310. In other words, when the switch of the electric vacuum cleaner 3 is opened, the communication port 513 is provided so that the air and dust in the internal space 525 can be sucked.

The shape of the communication port 513 is not limited to a substantially rectangular shape. For example, the shape may be circular, elliptical, triangular, hexagonal. The number of the communication ports 513 is not limited to seven. One or more than seven may be used. However, the flow rate of the fluid passing through the holes can be increased by making a plurality of small holes as compared with one large hole, and the remaining of 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 electric vacuum cleaner 3 sucks air and dust in the internal space 525 of the suction unit mounting table 510 through the communication port 513. On the other hand, the inner space 525 of the suction holder table 510 can receive the head portion 451 of the auxiliary dust collector 450 through the insertion port 523. The dust attached to the head portion 451 is sucked into the electric vacuum cleaner 3 through the communication port 513. Thereby, the head 451 of the auxiliary dust collecting member 450 can be cleaned.

The mounting portion 511 has one or more (six in the example shown in fig. 10) protruding portions 515 that protrude in the internal space 525. Each of the protruding portions 515 is disposed between adjacent communication ports 513. For example, the secondary dust collecting member 450 includes a plurality of rags of feathers or fibers at its head 451. When the head portion 451 of the auxiliary dust collecting member 450 moves in the inner space 525, each of the protrusions 515 enters between feathers or fibers of the head portion 451, and scoops out dust attached thereto. This enables the head 451 to be cleaned more cleanly.

The plurality of projections 515 are arranged in parallel with each other. This enables the air flow to be combed by the plurality of communication ports 513, and as a result, dust can be efficiently sucked.

As shown in fig. 10, the dimension in the height direction Z of the insertion opening 523 of the front face 521 is defined as a dimension H5. The dimension of the insertion port 523 in the width direction X 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 of the head portion 451 in the height direction Z in the natural state is defined as a dimension H6. The dimension of the head portion 451 in the width direction X in the natural state is defined as a dimension W6. The natural state referred to herein is a state in which the head 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 opening 523 has an area smaller than the sectional area of the head portion 451. Thereby, the head 451 is filled into all the insertion ports 523. Since air leakage can be prevented or reduced by insufficient filling of the insertion port 523, the suction force of the electric vacuum cleaner 3 can be effectively utilized.

As shown in fig. 11, a dimension in the depth direction Y of the region of the internal space 525 into which the head portion 451 is insertable is defined as a dimension L5. As shown in fig. 10, the dimension of the insertion direction Y of the head portion 451 is defined as a dimension L6. Dimension L5 is smaller than dimension L6. Thus, even if the head portion 451 is inserted into the innermost surface, the head portion 451 is maintained in a state of being filled into the entire insertion port 523. Therefore, the suction force of the electric vacuum cleaner 3 can be effectively used.

The suction unit mounting base 510 is formed in a T-shape, and the support 540 is erected on an extending portion extending rearward. The inner space 525 is also formed with an extension portion. This makes it possible to sufficiently secure the depth direction Y dimension of the internal space 525 while forming the suction mount table 510 to be narrow. Also, since the extension portion is located at the center in the width direction (X), the balance of the support 540 can be more preferably achieved.

Also, there are cases where the influence of air leakage is not or small. In this case, the dimension L5 may be the same as or larger than the dimension L6. This enables the head 451 to be cleaned as a whole.

As shown in fig. 12, the suction table 510 includes a positioning portion 527 in the placement portion 511. The positioning part 527 assists the electric vacuum cleaner 3 to be disposed to an appropriate position of the suction member 310. With the suction tool 310 disposed at an appropriate position, the suction port 323 of the suction tool 310 faces the one or more communication ports 513 of the placement portion 511. The positioning portion 527 includes a first protruding piece 529 located at the front end of the placing portion 511. The mounting portion 511 is inclined so that the rear end is higher than the front end. The positioning part 527 functions as a stopper for preventing the suction member 310 from rolling down in the front direction. When the suction tool 310 is placed on the placement portion 511, the first projecting 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 includes two second projecting pieces 531 located at the middle portion of the placement portion 511 in the depth direction Y and at the rear end of the communication port 513. When the suction tool 310 is placed on the placement portion 511, the second protrusions 531 abut against the inner wall 315 of the suction tool 310, and restrict the movement of the suction tool 310 in the depth direction Y and the width direction X.

The first protruding piece 529 and the second protruding piece 531 are also members for increasing the fluid resistance of the gap between the suction piece 310 and the placement portion 511. This can prevent or reduce air leakage through the gap between the suction tool 310 and the placement portion 511, and as a result, the suction force of the electric vacuum cleaner 3 can be effectively used for cleaning the head portion 451.

The suction material 310 has grooves 329 communicating with the suction port 323 on both side surfaces of the suction material 310. Air can be sucked through the groove 329 even from the lateral direction. The second protruding piece 531 of the suction device table 510 may also have a function of blocking the groove 329. This can prevent or reduce air leakage through the groove 329.

As shown in fig. 12, the suction inlet 323 at the bottom of the suction member 310 includes a first region 325 where the rotating brush 319 exists and a second region 327 between the rotating brush 319 and the inner wall 315. The second region 327 is adjacent to the first region 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 resistance. In contrast, since the second region 327 of the suction port 323 does not include the rotating brush 319, it has a relatively low fluid impedance. Thus, air is drawn primarily through 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 of the protruding portions 515 of the placing portion 511 has a first blade portion 517 and a second blade portion 519. The second blade portion 519 has a larger size 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.

Since a large amount of dust can be scraped out in the lower portion of the second region 327 in this manner, the suction residue of dust in the internal space 525 can be prevented or reduced.

The shape of the protruding portion 515 is not limited to the above configuration, 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 toward the rear end, and conversely, the height may be gradually decreased from the front end toward the rear end.

The positioning portion 527 is not limited to the above configuration, and may be provided along the entire circumference of the suction material 310. Further, instead of the protruding piece protruding from the placement portion 511, a concave portion recessed from the placement portion 511 may be used that is adapted to the shape of the suction piece 310.

The insertion port 523 may be provided not in the front surface 521 but in the side surface.

2-2. Support post

As shown in fig. 1, the support column 540 is disposed at the rear end of the suction mount table 510. The pillar 540 has a tapered surface 541 and a concave surface 543 at an upper portion thereof. The tapered surface 541 is adapted to (conforms to) the end surface 371 of the enlarged portion 363 of the cleaner body 340. The concave surface 543 is fitted to 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 is maintained in a standing state.

Preferably, the stay 540 is provided with a charging mechanism 545 for charging a battery of the electric vacuum cleaner 3. The charging mechanism 545 includes, for example, a circuit module 547 disposed in the pillar 540 and a connector receiver 549 disposed on the tapered surface 541. The circuit module 547 generates dc power suitable for charging a battery from ac power of a commercial power supply, for example. The connector receiver 549 is adapted to be provided at a connector 379 (see fig. 5) of the cleaner body 340 to electrically connect the circuit module 547 and the battery. The stay 540 charges the battery inside the cleaner body 340 while maintaining the cleaner body 340 in a standing state. Even in the charging of the battery, the electric vacuum cleaner 3 may be designed to drive the electric blower when the switch is turned on.

< second embodiment >

As shown in fig. 13, an electric vacuum cleaner 1001 according to the second embodiment includes an electric vacuum cleaner 1003 and a cleaner support device 1005.

The electric vacuum cleaner 1003 includes a suction tool 1310, a cleaner main body 340, and a handle tool 390 in this order, and is a so-called stick-type vacuum cleaner.

In the second embodiment, the width direction X, the depth direction Y, and the axial direction Z are defined similarly to the first embodiment.

The electric vacuum cleaner 1003 includes a housing section 410 for housing the auxiliary dust collector 450 so that the auxiliary dust collector 450 can be freely removed from the handle 390, as in the first embodiment. The storage 410 is attached to the cleaner main body 340. The electric vacuum cleaner 1003 is charged from the cleaner support 1005.

The cleaner support device 1005 includes: a suction unit mounting table 1510 for mounting a suction unit 1310 of the vacuum cleaner 1003 thereon; and a stay 540 supporting the cleaner main body 340 of the electric vacuum cleaner 3.

In the second embodiment, a part of a suction tool 1310 of the electric vacuum cleaner 1003 and a suction tool mounting table 1510 of the vacuum cleaner supporting apparatus 1005 are different from those of the first embodiment. Therefore, the following description will focus on these differences. The same reference numerals are used for the same components as those of the first embodiment, and the description of the components is omitted.

1. Inhalation piece

As shown in fig. 14(a), the suction piece 1310 has a suction space 1312 therein, which 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 duct 1320 via a communication port 1317 of an inner wall 1315 constituting the space. The dust collection duct 1320 is detachably connected to (the inner space of) the second cylindrical portion 373 of the cleaner main body 340.

1-1. Suction inlet

The suction port 1323 includes a first region 1325 and a second region 1327, and the suction space 1312 includes: a first space 1314 present on the back side of the first region 1325 and a second space 1316 present on the back side of the second region 1327.

The leading end of the first space 1314 forms an arrow to distinguish the lead wire from the lead wire in the first region 1325, the rotating brush 319, the inner wall 1315, and the like. Similarly, the front end of the second space 1316 forms an arrow to distinguish the lead wire from the lead wire of the second region 1327, the inner wall 1315, and the like.

As shown in fig. 14(a), the first space 1314 has a substantially long cylindrical shape in the width direction X. The first space 1314 houses a rotating brush 319 that is long in the width direction X and has a rotation axis in the width direction.

A second space 1316 exists between the first space 1314 (rotating brush 319) and the communication port 1317. Thereby, the dust scraped by the rotating brush 319 is directed from the second space 1316 to the communication port 1317.

That is, the suction unit 1310 has two spaces adjacent to each other in the depth direction Y, one of which is a first space 1314 for accommodating the rotating brush 319, and the other of which is a second space 1316 for generating a rotating airflow.

The rotating brush 319 is one or more brushes arranged in a spiral, for example, at the axis of rotation. Further, a plate-like body made of a rubber material or the like may be used as the brush, or a plurality of fibrous bodies made of a resin or the like may be used. When a fibrous body is used, a static elimination fiber such as an organic conductive fiber obtained by chemically bonding copper sulfide to an acrylic fiber or a nylon fiber may be used as all or a part of the fibrous body.

As shown in fig. 14(b), the middle portion in the width direction X of the second space 1316 is formed as a straight portion 1316a whose cross-sectional shape is constant in the width direction X. Both side portions of the second space 1316 in the width direction X are formed into tapered portions 1316b having substantially the same cross-sectional shape and gradually decreasing in area toward the end portions.

The shape of the cross section (inner wall shape) of the second space 1316 perpendicular to the width direction X is a shape in which the cleaning surface side is absent out of a circular shape or a substantially circular shape.

As shown in fig. 14, the communication port 1317 is provided in such a manner as to be located in the second space 1316, i.e., on the opposite side from the first space 1314. By configuring the cross-sectional shape of the second space 1316 and the position of the communication port 1317 in the above manner, it becomes easy to generate a swirling air flow in the second space 1316. Also, since the second space 1316 is divided into the first space 1314 and the dividing wall 1315 a. The generation of the swirling airflow by the swirling brush 319 is not hindered. The widthwise X end of the tapered portion 1316b communicates with the outside via the groove 329.

The communication port 1317 is formed to be long in the width direction X. That is, the rotary brush 319 is formed to have a shape elongated along the axial center thereof. The communication port 1317 is provided in the linear portion 1316a of the second space 1316.

Between the first space 1314 and the second space 1316, there is a protruding portion 1318 protruding from the first space 1314 side. The extension 1318 is formed of a different material from the bottom cover 1313 forming the dust collection space 1312.

A partition wall 1315a that divides the first space 1314 and the second space 1316 is included in the inner wall 1315, and a protruding member is detachably attached to a cutout portion in the middle portion in the width direction X of the partition wall 1315 a.

The protrusion 1318 is provided so as to be able to contact the rotary brush 319. As shown in fig. 15, the protruding portion 1318 protrudes in the direction opposite to the rotation direction of the rotary brush 319 (the arrow direction in the figure). I.e., in a brush-up direction by contacting the rotary brush 319. Thereby, the dust scraped off by the rotary brush 319 around the suction port 1323 is separated from the rotary brush 319. The extension 1318 here is made of, for example, a rubber material. This can suppress excessive consumption of the rotary brush 319. The extension 1318 may be made of a material capable of removing electricity, and may prevent dust from being adsorbed by static electricity.

The dust separated from the rotating brush 319 is sucked into the adjacent second space 1316, and then is sucked into the cleaner main body 340 from the communication port 1317 through the dust collection duct 1320.

When the suction port 1323 is viewed from the bottom side (i.e., the state of fig. 14 (b)), the protruding portion 1318 is provided in the middle portion in the width direction X. As shown in fig. 16(b), the protruding portion 1318 is longer than the entire length of the straight portion 1316a of the second space 1316 and shorter than the entire length of the second space 1316. The overall length of the protruding portion 1318 in the present embodiment is equal to the overall length of the linear portion 1316a plus the lengths of the tapered portions 1316b on both sides, which are 0 (%) to 50 (%), but the length is not limited to this and may be equal to the entire length of the rotary brush 319.

As shown in fig. 14(b), the length of the extension 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), the protruding portion 1318 faces the communication port 1317 across the second space 1316. Thereby, the dust scraped off by the protrusion 1318 is efficiently sucked from the communication port 1317.

As shown in fig. 16(b) and 17, the lower end of the extension 1318 in the axial direction Z is configured so as not to reach the cleaning surface. Thus, the dust scraped off by the protrusion 1318 effectively moves to the second space 1316.

As shown in fig. 16b, the extension 1318 is located on the partition wall 1315a on the opposite side of the cleaning surface from the lower end (end on the cleaning surface side) of the end in the width direction X. That is, the lower end of the protruding portion 1318 is higher than the lower end of the partition wall 1315a constituting the tapered portion 1316b of the second space 1316 with respect to the cleaning surface. This improves the sealing performance of the second space 1316 at the tapered portion 1316b, and enhances the swirling air flow from the end in the width direction X in the second space 1316 toward the communication port 1317.

As shown in fig. 15, the lower end of the extension 1318 in the axial direction Z is higher than the lower end of the communication port 1317.

1-2. Dust collecting duct

(1) Integral structure

As shown in fig. 18, dust collection duct 1320 includes: a communication side guide pipe 1322 disposed to face the second space 1316, a main body side guide pipe 1324 disposed on the cleaner main body 340 side, and a connection guide pipe 1326 rotatably connected to the main body side guide pipe 1324 about an X axis parallel to the width direction X and a Y axis parallel to the depth direction Y with respect to the communication side guide pipe 1322. Also, connecting conduit 1326 is comprised of connecting downcomer 1328 and connecting downcomer 1330.

The upstream side opening of the communication side pipe 1322 is fitted to the bottom cover 1313 in a fixed state in which it is fitted to an 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 side opening of the communication side pipe 1322 functions as a communication port 1317.

The downstream end of the main body side duct 1324 functions as a connection portion with the cleaner main body 340, and is also electrically connected to the rotary brush 319 so as to be rotationally driven by a driving portion (not shown).

The connection pipe 1326 is rotatably connected to the connection side pipe 1322 around a Y axle. Main body side duct 1324 is connected to connection duct 1326 so as to be rotatable around the X axle. The dust collection duct 1320 has a restriction releasing structure for releasing the restriction of rotation of the connection duct 1326 while restricting the rotation around the Y-axis with respect to the connection side duct 1322.

(2) Communicating side conduit and connecting conduit

As shown in fig. 19(a), the connection between the communication-side conduit 1322 and the connection conduit 1326 is fixed by a C-shaped fixing member 1331 in a state in which the cylindrical portion 1322a on the downstream side of the communication-side conduit 1322 is fitted into a cylindrical fitting portion 1328a that connects the upstream end portion of the lower conduit 1328.

In order to insert the cylindrical portion 1322a into the fitting portion 1328a, a cylinder axis of the cylindrical portion 1322a becomes a Y-axis as a rotation axis, and the connection pipe 1326 is rotatable with respect to the connection side pipe 1322. In this state, the cylindrical portion 1322a can be pulled out from the fitting portion 1328 a.

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 has through holes 1328b, 1328c in the fitting portion 1328a at a position corresponding to the circumferential groove 1322b of the cylindrical portion 1322a (see fig. 18). The protrusions 1331a, 1331b of the C-shaped fixture 1331 are inserted through the through holes 1328b, 1328C of the connecting downcomer 1328, and are fitted into the peripheral groove 1322b of the communication-side conduit 1322. This prevents the connecting pipe 1326 (connecting downcomer 1328) from coming off the communication-side pipe 1322.

The description is made in detail.

The fitting portion 1328a to which the downcomer 1328 is connected has a circumferentially extending groove 1328d for the fixing member 1331, and through holes 1328b, 1328c are provided in the bottom wall of the groove 1328 d. Specifically, the positions of the through holes 1328b, 1328c correspond to the positions of the protrusions 1331a, 1331b of the fixture 1331. The "C" -shaped fastener 1331 is formed in an arc shape longer than a semicircle, the protrusion 1331a is located at the approximate center of the arc, and the protrusions 1331b are located at both ends of the arc. Thus, the securing member 1331 is difficult to disengage from the connecting downcomer 1328. The fixing member 1331 is fixed to the connection tube 1326, and not only the fixing member 1331 rotates.

As shown in fig. 19, the restriction releasing structure includes an engaged portion 1322c provided in the communication-side pipe 1322 and an engaging portion 1331c provided on the connection pipe 1326 side (here, the fixture 1331).

The engaged portion 1322c has a concave portion 1322d recessed in a direction parallel to the cylinder axis on the opposite side to the side where the fixing piece 1331 exists. The engaging portion 1331c has a convex portion 1331d that protrudes toward the communication-side pipe 1322 and in a direction parallel to the cylinder axis. When male portion 1331d is engaged with female portion 1332d, rotation of communication-side conduit 1322 with respect to connecting conduit 1326 is restricted.

When viewed from a direction orthogonal to the engagement direction (fig. 19 (c)), the concave portions 1322d and the convex portions 1331d have an arc-like shape. This allows the rotation restriction to be smoothly released.

When the restriction releasing structure is viewed from the direction orthogonal to the engaging direction (fig. 19 (c)), the engaged portion 1322c has inclined portions 1322e that are separated from the fixing piece 1331 on both sides of the concave portion 1322d as they are separated from the concave portion 1322d in the circumferential direction. Thus, even if the engaging portion 1331c (the convex portion 1331d) is located at a position (in a state where rotation is not restricted) apart from the engaged portion 1322c in the circumferential direction, the convex portion 1331d can be smoothly engaged with (fitted into) the concave portion 1322d by rotation on the connection pipe 1326 side.

As shown in fig. 19(a) and (b), the engaged portion 1322c is provided on an outer cylindrical portion 1322f coaxially with the cylindrical portion 1322a, and the engaged portion 1322c is positioned on a rail to which an engaging portion 1331c during rotation of the downcomer 1328 is connected.

The fixing piece 1331 has an engaging portion 1331c that is elastically deformable in a direction parallel to the cylinder axis. Specifically, the fixing piece 1331 has a U-shaped portion 1331f extending in a reverse "U" shape radially outward from the C-shaped main body portion 1331e, and an engaging portion 1331C is provided in the U-shaped portion 1331 f.

Thus, when the connection pipe 1326 is rotated with respect to the communication side pipe 1322, the engaging portion 1331c is elastically deformed on the side opposite to the communication side pipe 1322, and the male portion 1331d can be smoothly engaged with the female portion 1322d or disengaged from the female portion 1322 d.

In order to restrict detachment of communication side conduit 1322 from connection conduit 1326, fixture 1331 has a rigidity (thickness) that does not break even if a load is applied. However, by providing the engaging portion 1331c in the U-shaped portion 1331f having a space with the main body portion 1331e, the U-shaped portion 1331f is elastically deformed in the engaging direction (here, the direction parallel to the cylindrical axis direction of the cylindrical portion 1322a of the communication side conduit 1322) by an appropriate load, and the engaged state of the convex portion 1331d and the concave portion 1322d can be prevented from becoming difficult to release.

By adopting the U-shaped portion 1331f and appropriately selecting the space between the main body portion 1331e and the U-shaped portion 1331f in this manner, the engagement or disengagement of the male portion 1331d and the female portion 1322d can be adjusted. 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.

The suction unit 1310 is provided with a driving unit (not shown) for rotationally driving the rotary brush 319. Generally, a communication side guide 1322 and the like are provided in the center portion of the suction piece 1310 in the width direction X, and the driving unit is disposed in a state shifted from the center of the suction piece 1310 in the width direction to one side in the width direction. Therefore, when the suction tool 1310 is lifted up in use, a load is generated to rotate the communication side conduit 1322 with respect to the connection conduit 13326 due to the influence of the rotational torque caused by the weight of the driving unit. The U-shaped portion 1331f is not elastically deformed (the engagement state is not released) with respect to the load of the rotation, and thus, the shake when the suction piece 1310 is lifted can be eliminated.

2. Dust collector supporting device

The cleaner support 1005 supports the electric cleaner 1003. The cleaner supporting apparatus 1005 is a charging station for charging a battery incorporated in the electric cleaner 1003. As shown in fig. 13, the cleaner supporting apparatus 1005 includes a suction tool mounting table 1510 for mounting a suction tool 1310 of the electric cleaner 1003 thereon, and a support 540 for supporting the electric cleaner 3 (cleaner main body 340), and the suction tool mounting table 1510 includes a nozzle holding portion 1535 for holding a gap nozzle 1007 attached in place of the suction tool 1310.

As shown in fig. 20, the suction holder mounting table 1510 includes a mounting portion 511 on which the suction holder 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 has an internal space 525 below the mounting portion 511, i.e., between the mounting portion 511 and the base portion 1530, and the internal space 525 is open in front of the insertion port 523 that can receive the head portion 451 of the auxiliary dust collector 450. The mounting portion 511 has a plurality of communication ports 513 communicating with the internal space 525 along the axial direction of the rotary brush 319. The mounting portion 511 includes a first projecting piece 529 as a positioning portion of the suction piece 1310 in the mounting portion 511.

The base portion 1530 has a recessed portion 1533 recessed toward the installation surface side on the surface on the mounting portion 511 side, and an electricity removing member, here an iron plate 1534, is disposed in the recessed portion 1533. Also, 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 formed of an inclined surface that descends forward.

The iron plate 1534 has a function of removing charges charged in the head 451 of the auxiliary dust collector 450. The iron plate 1534 is disposed in a position close to the installation surface, and has a function of supporting the electric vacuum cleaner 1003 in a stable state. The iron plate 1534 is larger than the width direction (X) of the insertion opening 523, and extends further toward the opposite side of the internal space 525 than the side wall 525a forming the internal space 525. This eliminates the need for a special structure for fixing the iron plate 1534, and can be easily implemented.

When the suction tool mounting table 1510 is viewed from above, the suction tool mounting table 1510 has a nozzle holding portion 1535 behind the mounting portion 511. The nozzle holder 1535 here includes a projecting portion 1536 projecting from the base portion 1530 and a cylindrical portion 1537 extending upward from the projecting portion 1536. The gap nozzle 1007 is detachably supported by fitting the cylindrical portion 1071 to the outside of the cylindrical portion 1537.

The extension portion 1536 is provided so as to be received in a rectangular region having a dimension in the width direction X of the mounting portion 511 or the base portion 1530 and a dimension in the depth direction Y of the mounting portion 511 and the support 540 as both sides. This allows the gap nozzle 1007 to be held without substantially increasing the installation area of the cleaner holder 1005.

< third embodiment >

In the first embodiment, the handle 457 of the auxiliary dust collecting member 450 is held between the pair of plate-like portions 401 of the electric vacuum cleaner 3.

However, in the third embodiment, the auxiliary dust collector 2450 is held by an engagement structure with the electric vacuum cleaner 2003. The holding unit and the auxiliary dust collector 2450 of the electric vacuum cleaner 2003 will be described below.

As shown in fig. 21, the electric vacuum cleaner 2003 has a holding portion that holds the auxiliary dust collection member 2450. The holding portion here is constituted by an engaging portion 2399 which engages with an engaged portion 2458 of the shank 2457 of the auxiliary dust collecting member 2450.

The engagement relationship may be such that the engaged portion of the electric vacuum cleaner is engaged by the engaging portion of the handle of the auxiliary dust collecting member.

Here, the engaged portion 2458 of the auxiliary dust collecting member 2450 is constituted by an inverted U-shaped plate portion 2458a extending in an inverted "U" shape from an end portion of the head portion 451 of the shank 2457 on the opposite side, and the catching portion 2399 is constituted by an L-shaped plate portion 2399a extending in an "L" shape on the opposite side of the head portion 451 of the auxiliary dust collecting member 2450.

The L-shaped plate portion 2399a is engaged with a through hole 2460 formed by the inverted U-shaped plate portion 2458a and the end face 2457a of the shank 2457, whereby the shank 2457 of the auxiliary dust collection member 2450 is supported by the electric vacuum cleaner 2003.

As shown in an enlarged view, the engaging portion 2399 has a convex region 2399b protruding inward at the tip of the L-shaped plate portion 2399 a. This prevents the inverted U-shaped plate portion 2458a from being pulled out from the L-shaped plate portion 2399 a.

Instead of the convex region 2399b, the engaging portion may have a groove into which the L-shaped plate portion is fitted (tightly fitted).

The electric vacuum cleaner 2003 herein has a convex portion 2392 protruding to the back side at a grip portion 2390. This reduces the risk of the grip section 1390 slipping off the user's hand during use of the electric vacuum cleaner 2003.

As shown in fig. 22, the shank 2457 of the auxiliary dust collecting member 2450 includes a cylindrical first portion 2459 and a cylindrical second portion 2463, as in the first embodiment. The second portion 2463 is inserted into the first portion 2459 and is configured to be telescopic 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 2463 has an operation button 2464 protruding outward from a through hole 2463a on the opposite side of the head portion 451 in the longitudinal direction.

The operation button 2464 includes a button portion 2466 fitted into the through holes 2459a and 2459b of the first portion 2459 and supported in the thickness direction (inner and outer direction) of the first portion 2459 and the second portion 2463, and an elastic spring 2468 for biasing the button portion 2466 in the inner and outer direction of the through hole 2463 a.

When the auxiliary dust collector 2450 is stored in the storage section 410 of the electric vacuum cleaner 2003, the second section 2463 is inserted into the first section 2459, and the button 2466 is fitted into the through hole 2459a of the first section 2459. This allows compact storage while maintaining the compact state.

When the auxiliary dust collector 2450 is used, the button portion 2466 is pushed into the first portion 2459, and the fitting state of the button portion 2466 into the through hole 2459a is released. 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. Thus, the second portion 2463 can be used in a long state drawn out from the first portion 2459.

Here, two through holes 2459a and 2459b of the first portion 2459 are provided on both sides in the longitudinal direction, but three or more through holes may be provided at intervals in the longitudinal direction. This enables more precise length adjustment.

The embodiment has been described above, but the present invention is not limited to this embodiment, and the following modifications are possible, for example. Further, the embodiment, the modification and the modification may be combined.

In addition, even examples not described in the embodiment and the modification are included in the present invention as long as design changes are made without departing from the scope of the present invention.

< modification example >

(1) In the above embodiment, the electric vacuum cleaner apparatus 1 includes both the housing section 410 housing the auxiliary dust collector 450 and the structure (the insertion port 523, the internal space 525, the communication port 513) for cleaning the auxiliary dust collector 450 of the cleaner support device 5. The present invention is not limited thereto, and may include only one.

(2) In the above embodiment, the cleaner supporting apparatus 5 includes the charging mechanism 545, but the present invention is not limited thereto. The cleaner support device 5 may not have the charging mechanism 545.

In the above embodiment, the electric vacuum cleaner 3 is a vacuum cleaner without a power cord, but is not limited thereto. Also can be a dust collector with a power line.

(3) Although the head main body 453 of the auxiliary dust collecting member 450 is not particularly described in the above embodiment, for example, when a fibrous body such as a wiper or a brush is used as the head main body, a polypropylene tear yarn (split yarn) is preferably used. By using this, dust and the like can be easily captured, and the head main body is inserted into the internal space 525 of the suction tool mounting tables 510, 1510, so that the dust can be favorably detached (released) from the fibrous body when sucked by the vacuum cleaners 3, 1003.

That is, the fibrous main body of the head main body inserted into the internal space 525 can suck dust from the head main body without being entangled with a rotating brush (nylon fiber) of the electric vacuum cleaner.

(4) The restriction canceling structure is not limited to the description of the second embodiment, and focusing on the restriction canceling structure, the type of the electric vacuum cleaner (rod type, can type), the presence or absence of the auxiliary dust collector or the housing portion, the presence or absence of the cleaner support device, the presence or absence of the second space, and the like do not matter.

In the case where the restriction releasing structure is connected to the second pipe side (for example, a second pipe or a peripheral member of the second pipe as the connection pipe) rotatably with respect to the first pipe side (for example, a first pipe as the communication-side pipe or a peripheral member of the first pipe), the second pipe side has an engaging portion that engages with the engaged portion on the first pipe side and restricts rotation with respect to the first pipe, and at least one of the engaged portion and the engaging portion is configured to be elastically deformable so as to allow the second pipe to rotate with respect to the first pipe. This makes it possible to easily release and restore the engagement relation.

In the second embodiment, the engaging portion 1331c is provided in the fixing member 1331 (an example of the peripheral member) fixed to the second conduit, but the engaging portion may be provided in the connecting conduit 1326. That is, the member that rotates integrally with the second duct may have an engagement portion.

In the second embodiment, the pulled-up portion 1322c is provided to the communication-side conduit 1322 of the first conduit, but an engaged portion or an engaging portion may be provided to a bottom cover (an example of a peripheral member) to which the first conduit is attached, and an engaged portion or an engaging portion may be provided to an upper cover (an example of a peripheral member).

In the second embodiment, the engaging portion 1331c of the fixing member 1331 is configured to be elastically deformable, but may be configured such that the engaged portion on the first pipe side is elastically deformable, or may be configured such that the engaged portion and the engaging portion are elastically deformable.

In the second embodiment, the engaging portion 1331c may be formed of a convex portion 1331d protruding in a direction parallel to a rotation axis of rotation with respect to the first conduit, and the engaged portion 1322c may be formed of a concave portion 1322d recessed in a direction parallel to the rotation axis. However, the relationship between the engaged portion and the engaging portion may be reversed. That is, the engaging portion of the male portion may be located on the first catheter side, and the engaged portion of the female portion may be located on the second catheter side.

Further, although the convex portion and the concave portion are provided in parallel with the rotation axis, they may be provided outward or inward in a direction orthogonal to the rotation axis.

In the second embodiment, the U-shaped portion 1331f provided with the convex portion 1331d in the fixing piece 1331 is elastically deformable, but the convex portion may be formed as a sheet, for example, and the convex portion itself may be configured to be elastically deformable.

(5) Although the suction devices 310 and 1310 according to the first and second embodiments include a space (first space) for accommodating the rotating brush 319 and a space (second space) capable of generating a whirling airflow, the suction device may include 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, and the second space may be a space in which the whirling airflow is not generated.

The second space 1316 may be tapered 1316b in a direction parallel to the rotation axis of the rotating brush 319 and at both side portions thereof, but may not be tapered. Further, the swirling airflow is generated even if both side portions are not tapered, but strong swirling airflow can be obtained by tapering.

The front-rear positional relationship between the first space and the second space is not particularly limited. However, it is preferable that the second space exists in the first regions 325 and 1325 of the suction ports 323 and 1323 on the downstream side in the rotation direction of the rotating brush 319.

In the second embodiment, the extension portion 1318 is provided between the first space 1314 and the second space 1316, and the sealing degree between the cleaning surfaces of the tapered portion 1316b of the second space 1316 is greater than that of the cleaning surfaces of the linear portion 1316a, but the sealing degree of the tapered portion 1316b may be the same as that of the linear portion 1316a or may be lower than that of the linear portion 1316 a. However, when a strong swirling flow is used, the sealing degree of the tapered portion 1316b may be higher than that of the linear portion 1316 a.

Focusing on the whirling airflow, the type of the vacuum cleaner (rod type, canister type), the presence or absence of the auxiliary dust collector or the housing unit, the presence or absence of the cleaner support device, and the like are irrelevant.
