  1. Electric vacuum cleaner

As shown in FIG. 1, the vacuum cleaner unit 1 includes a vacuum cleaner 3 and a vacuum cleaner support device 5. The electric vacuum cleaner 3 is a so-called stick-type vacuum cleaner including a suction tool 310, a cleaner body 340, and a handle 390 in this order. The vacuum cleaner 3 includes an accommodating portion 410 for accommodating the auxiliary dust collector 450 so as to be able to be taken out from the hand tool 390 side. The housing section 410 is mounted on the cleaner body 340. The vacuum cleaner 3 is a portable type that is charged from the vacuum cleaner support device 5.
Here, the direction in which the suction tool 310, the cleaner main body 340, and the handle tool 390 in the vacuum cleaner 3 are arranged in this order is defined as an axial direction (Z), and the suction port 323 of the suction tool 310 (the rotation axis of the rotating brush 319) is positioned. The extending direction is defined as the width direction (X), and the direction orthogonal to the axial direction and the width direction (the direction in which the rotating brush 319 travels) is defined as the depth direction (Y).

  1-1. Vacuum cleaner body

  The cleaner main body 340 includes a cylindrical housing 341. The cylindrical housing 341 includes a first cylindrical portion 343, a cylindrical extended portion 363, and a second cylindrical portion 373. The extension portion 363 is located between the first cylindrical portion 343 and the second cylindrical portion 373, and has a 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 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 cleaner body 340 has the extended portion 363 having a large outer peripheral dimension on the way from the handle 390 to the suction tool 310. The expanded 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, in addition to the outer peripheral surface 365. Both the end surface 369 and the end surface 371 are tapered.

  The shape of the 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. It may have a reduced portion. Further, the shape of the cleaner 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 quadrangular cross section, a hexagonal cross section, and an octagonal cross section, or a combination thereof, or an asymmetric shape May be used.

  The cleaner main body 340 includes, for example, components such as an electric blower, a battery, a circuit module, a dust collecting pack mounting portion, and an indicator 377. These components are housed in a cylindrical housing 341. For example, the first cylindrical portion 343 houses a battery, a circuit module, and an indicator 377. The extension 363 houses an electric blower. The second cylindrical portion 373 accommodates a dust collecting pack mounting portion and a dust collecting pack. The battery stores power received from a 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 collection pack mounting portion detachably mounts a dust collection pack that stores sucked dust. The circuit module executes 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 an outer peripheral surface 349 thereof. The indicator 377 is arranged so as to be visible to the outside through the oval 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 390 is detached, the operation of the vacuum cleaner 3 becomes possible.

  The cleaner main body 340 has an attaching means for detachably attaching the handle 390. The engaging portion, which is an example of the attaching means, is not shown in FIG. 1 because it is fitted inside the handle 390. By operating the attachment button 375 on the handle 390 side, the engagement protrusion on the handle 390 side is engaged with the engagement recess on the cleaner body 340 side. The attachment means is not limited to this, and may be a screw.

  The cleaner main body 340 has an attachment structure for detachably attaching the housing section 410. Details of this will be described later.

  1-2. Handle

  The handle 390 includes a cylindrical housing 391 having a closed upper surface and an open lower surface. The cylindrical housing 391 has a through hole 395 for operating the mounting button 375. The mounting button 375 is exposed to the outside of the cylindrical housing 391 through the through hole 395. When the mounting button 375 is pushed into the inside of the cylindrical housing 391, the engagement between the engaging concave portion and the engaging convex portion can be released. Thus, the cylindrical housing 391 and the handle 390 can be removed from the cleaner body 340. Note that the handle 390 may be detachably attached to the cleaner main body 340 by another method. Further, the handle 390 may be irremovably attached to the cleaner body 340. For example, the handle 390 may be formed integrally with the cleaner body 340.

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

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

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

  The handle 390 includes a holding section 399 that holds the auxiliary dust collecting tool 450 housed in the housing section 410. Details of this will be described later.

  1-3. Suction tool

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

  The suction tool 310 has a dust collection pipe connecting the second cylindrical portion 373 of the cleaner body 340 and the suction port 323 of the suction tool 310 inside. The inner wall 315 has a communication port 317 communicating with the dust collection pipe. The dust sucked from the suction port 323 is sent to the dust collection pack stored in the second cylindrical portion 373 through the communication port 317 and the dust collection pipe.

  The suction tool 310 includes three rollers 321 on the bottom cover 313. As a result, the suction tool 310 can travel smoothly on a surface to be cleaned such as a floor, for example.

  1-4. Accommodation

  The accommodation section 410 has an opening 433 for accommodating the auxiliary dust collector 450 as shown in FIG. The auxiliary dust collecting device 450 is housed in the housing portion 410 so as to be able to be taken out from the handle 390 side. More specifically, the housing section 410 has a bottomed cylindrical shape with the opening 433 facing the handle 390 side. Thus, 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 a storage unit 410 that stores the auxiliary dust collector 450. Therefore, the cleaning by the vacuum cleaner 3 can be performed using the auxiliary dust collector 450 without hindering the mobility of the auxiliary dust collector 450.

  As shown in FIG. 3, the housing 410 includes a first side 411, a second side 415, a back 419, a front 425, and a bottom 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 long protruding pieces 413 on an opposing surface facing the second side surface portion 415. Here, “vertical” refers to a direction along the cylinder axis of the housing section 410. The two protruding pieces 413 are respectively disposed at two positions above and below the facing surface. Although not shown in FIG. 3, similarly, the second side surface portion 415 has two vertically long protruding pieces 413 on a facing surface facing the first side surface portion 411. The protruding piece 413 has a vertically long rectangular shape when the housing section 410 is viewed from the front side. The four protruding pieces 413 are provided at portions near the four corners of the housing portion 410, respectively. Thus, the housing portion 410 can be stably fixed to the first cylindrical portion 343. The shape and position of the protruding piece 413 are not limited to this, and one of the engaging portions is provided and the other is provided with the engaged portion so that the front surface portion 425 is attached to face the first cylindrical portion 343. It should just be done. For example, the protruding piece 413 may protrude from the front surface 425 in an L-shape.

  The front part 425 has a concave shape that fits the outer peripheral surface 349 of the first cylindrical part 343 of the cleaner body 340. The front surface 425 has two vertically long ridges 427 and one horizontally long engaging projection 429. Here, “lateral” refers to a direction (circumferential direction) perpendicular to the cylinder axis of the housing section 410.

  The back part 419 has a parallel part 421 substantially parallel to the front part 425 and an inclined part 423 inclined with respect to the front part 425. The inclined portion 423 is provided to increase 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 housing portion 410. Further, when removing the auxiliary dust collecting tool 450 from the storage section 410, the handle 457 can be inclined so as to be separated from the hand tool 390. The inclined portion 423 is for gradually narrowing the internal space of the housing portion 410 from the opening 433 toward the bottom surface portion 431. Thereby, the head part 451 of the auxiliary dust collector 450 can be smoothly moved from the opening 433 to the bottom part 431. The rear portion 419 is not limited to this, and may be substantially entirely parallel to the front 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 become wider in width from the bottom surface portion 431 toward the opening 433. In this case, the width may be gradually increased from the bottom surface portion 431 to the middle, and the width may be further increased from the middle to the opening 433 side.

  As shown in FIG. 3, the first cylindrical portion 343 of the cleaner body 340 has four vertically long guide grooves 353 on an outer peripheral surface 349 thereof. Here, “vertical” refers to 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 housing portion 410, respectively, and guide the housing portion 410 to an appropriate position.

The first cylindrical portion 343 has four vertically long projecting pieces 355 on an outer peripheral surface 349 thereof. The four protruding pieces 355 are disposed beside and behind the four guide grooves 353, respectively, and can be respectively engaged with the four protruding pieces 413 of the housing portion 410. Specifically, when the projecting piece 355 engages with the projecting piece 413, the front surface of the projecting piece 355 contacts the rear surface of the projecting piece 413. When the housing portion 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 portion 410 engage with the four protruding pieces 355 of the first cylindrical portion 343, respectively. I do. Thereby, the movement of the first cylindrical portion 343 of the housing portion 410 in a direction other than the cylinder axis direction is restricted.
In a state where the housing portion 410 is attached to the first cylindrical portion 343, the front ends of the first side surface portion 411 and the second side surface portion 415 are close to the outer peripheral surface 349 of the first cylindrical portion 343. Therefore, it is possible to prevent dust from entering between the housing portion 410 and the first cylindrical portion 343. In addition, a sense of unity between the housing portion 410 and the first cylindrical portion 343 can be obtained.

  As a result, the housing section 410 is detachably attached to the first cylindrical portion 343, and eventually to the cleaner main body 340. Therefore, the accommodating portion 410 can be cleaned by removing the accommodating portion 410 from the cleaner body 340.

  The first cylindrical portion 343 has one laterally long engaging concave portion 357 on an outer peripheral surface 349 thereof. Here, “lateral” refers to a direction (circumferential direction) perpendicular to the cylinder axis of the first cylindrical portion 343. The engagement concave portion 357 can be engaged with the engagement convex portion 429 of the housing portion 410. When the accommodating 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 is engaged with (fits into) the engaging concave portion 357. Thereby, the movement of the first cylindrical portion 343 of the housing portion 410 in the cylinder axis direction is restricted. However, the engagement between the engagement projection 429 and the engagement recess 357 is designed to be relatively loose. Therefore, the engagement between the engaging protrusion 429 and the engaging recess 357 can be released by intentional and forcible sliding of the housing portion 410. This makes it possible to prevent or reduce unintentional detachment of the housing portion 410 from the first cylindrical portion 343 while enabling the housing portion 410 to be attached to and detached from the first cylindrical portion 343.

  The front part 425 of the housing part 410 has the vertically long ridge 427 as described above. These ridges 427 form a clearance between the front surface 425 of the housing portion 410 and the outer peripheral surface 349 of the first cylindrical portion 343. The accommodation portion 410 contacts the first cylindrical portion 343 not with the front surface portion 425 but with the ridge 427. Thereby, the contact area of the housing portion 410 with the first cylindrical portion 343 can be reduced, and as a result, the sliding of the housing portion 410 on the first cylindrical portion 343 can be performed smoothly.

  The accommodation section 410 is attached to the first cylindrical portion 343 as shown in FIG. The bottom surface portion 431 of the housing portion 410 is along the end surface 369 of the extended portion 363 of the cleaner body 340 on the handle 390 side. Thereby, the accommodation part 410 and the cleaner main body 340 can be integrated.

As shown in FIG. 4, a dimension in the depth direction (Y) between the back portion 419 of the storage unit 410 and the central axis C of the cleaner body 340 is defined as a dimension L1. The dimension in the depth direction (Y) between the outer peripheral surface 365 of the extended portion 363 of the cleaner body 340 and the central axis C of the cleaner body 340 is defined as a dimension L2. The dimension in the depth direction (Y) between the rear surface of the wiring cover 367 and the central axis C of the cleaner body 340 is defined as a dimension L3. The dimension L1 is equal to or larger than the dimension L2. The dimension L1 is equal to or larger than the dimension L3. That is, the dimension L1 perpendicular to the central axis C of the cleaner body 340 and the dimension L1 in the depth direction (Y) of the outer peripheral surface 349 away from the mounting portion of the housing portion 410 with respect to the central axis C is the dimension L2 of the extended portion 363. It is about the same or more. In other words, the accommodating portion 410 is flush or protrudes in the depth direction (Y) with respect to the extended portion 363 of the cleaner body 340.
Note that the central axis C of the first cylindrical portion 343 is shifted from the central axis C of the expanded portion 363, so that the housing portion 410 is flush or retracted in the depth direction (Y) with respect to the expanded portion 363. May be.
The wiring cover 367 houses therein wiring for connecting the connector 379 (see FIG. 5) and the battery in the first cylindrical portion 343. The wiring cover 367 is exposed outside the extended portion 363, but is not limited to this. For example, the wiring cover 367 may be accommodated inside the extension portion 363.

  As shown in FIG. 5, the 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 size W1. The dimension in the width direction (X) of the extended portion 363 of the cleaner body 340 is defined as a dimension W2. Dimension W1 is equal to or smaller than dimension W2. That is, the dimension W1 in the width direction (X) perpendicular to the center axis C of the cleaner body 340 and perpendicular to the depth direction (Y) is equal to or smaller than the dimension W2 of the expanded portion 363.

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

  The accommodation section 410 is preferably made of a water-washable material. By appropriately washing the housing section 410 with water, the housing section 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 can be used.

As described above, the housing portion 410 can be removed from the first cylindrical portion 343. However, it is not limited to this. For example, the housing portion 410 may be formed integrally with a part of the back portion of the first cylindrical portion 343, and the housing portion 410 may be removed from the front portion of the first cylindrical portion 343 together with a portion of the back portion.
As described above, the housing section 410 is detachably attached to the cleaner body 340. However, the configuration is not limited thereto, and the housing unit 410 may be irremovably attached to the cleaner body 340. The accommodation section 410 may be formed integrally with the cleaner body 340.

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

  The accommodation section 410 may have one or more holes in the bottom section 431. This can prevent or reduce the accumulation of dust in the internal space of the housing section 410. Conversely, the housing portion 410 may employ a bottom surface portion 431 without a hole. Thus, it is possible to prevent dust from leaking from the internal space of the storage unit 410.

  The holding section 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 unit 399 is located near the cleaner main body 340 in the handle 390. As described above, the cleaner body 340 has the step 359 on the handle 390 side. Since the holding portion 399 is located near the step portion 359, it is possible to prevent an object from being caught on the holding portion 399. In addition, it is less likely that the user holds the handle portion 457 of the auxiliary dust collector 450 and removes the auxiliary dust collector 450 from the storage unit 410.

  The holding unit 399 includes a pair of plate-shaped portions 401, as shown in detail in FIG. The pair of plate-shaped portions 401 extend in a depth direction (Y) orthogonal to a direction (Z: axial direction) in which the suction tool 310, the cleaner body 340, and the handle tool 390 are arranged. Each plate-shaped portion 401 has a rectangular shape long in the axial direction (Z). Thereby, the handle 457 of the auxiliary dust collector 450 can be firmly held. The distal end in the depth direction (Y) of each plate-shaped portion 401 does not protrude from the outer peripheral surface 349 of the first cylindrical portion 343. Thereby, when the accommodating part 410 is slid for the attachment / detachment of the accommodating part 410, it can prevent that each plate-shaped part 401 interferes with the accommodating part 410. Each plate-shaped portion 401 has opposing surfaces 403 opposing each other. Thus, when the handle 457 of the auxiliary dust collector 450 is positioned between the opposing surfaces 403, the movement of the handle 457 in the width direction (X) can be restricted. The holding portion 399 includes a pair of vertically long convex portions 405. Each projection 405 protrudes from the opposing surface 403 of the plate-shaped portion 401 toward the other party. Each convex portion 405 is provided at the tip of the plate-shaped portion 401 in the depth direction (Y).

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

  The distance G1 between 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. Accordingly, the holding unit 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 detachment of the auxiliary dust collector 450 from the holding unit 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. Accordingly, 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 unit 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). Thus, the auxiliary dust collector 450 can be attached and detached by moving the auxiliary dust collector 450 in the depth direction (Y). In particular, the projection 405 has a tapered tip. This makes it easy to attach and detach the auxiliary dust collector 450 by moving in the depth direction (Y).

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

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

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

  1-6. Auxiliary dust collector

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

  The second portion 463 of the handle 457 has an engagement hole 467 for engaging the mounting button 455. The mounting button 455 is exposed outside the second portion 463 through the engagement hole 467. The attachment button 455 is firmly engaged with the engagement hole 467 by being urged by a spring force. As an example, a U-shaped cut is formed in the plate portion, and the mounting button 455 is provided in an inner portion of the U-shape. The inside portion of the U-shape is elastically deformable in the thickness direction with respect to other portions of the plate portion. Thereby, a spring force can be generated. When the 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 main body 453 and, consequently, the head part 451 can be removed from the second part 463 and, consequently, the handle part 457. The head 451 may be removably attached to the handle 457 by any other method. For example, the handle 457 and the head 451 may be attached with screws. The head 451 may be irremovably attached to the handle 457. For example, the head 451 may be formed integrally with the handle 457.

  As shown in FIG. 9, the first portion 459 of the handle 457 has a tubular shape with a substantially rectangular cross section. The first portion 459 has a ridge 461 protruding toward the internal space on a pair of side surfaces facing each other. The second portion 463 of the handle 457 has a tubular shape with a substantially square cross section, and is fitted inside the first portion 459. The second portion 463 has a guide groove 469 on a pair of side surfaces facing each other, the guide groove 469 being adapted to the ridge 461. Thus, the second portion 463 is slidably attached to the first portion 459. That is, the handle 457 can be extended and contracted. Thus, the handle 457 can be contracted when the auxiliary dust collector 450 is accommodated in the housing portion 410, and the handle 457 can be extended when the auxiliary dust collector 450 is used.

  The handle 457 has a bent portion 465 as shown in FIG. Further, as described above, the first cylindrical portion 343 of the cleaner body 340 has the step portion 359 formed by the tapered surface 347 and the upper surface 345. In a state in which the auxiliary dust collector 450 is accommodated in the accommodating portion 410 and is held by the holding portion 399, the bent portion 465 follows the step portion 359. Thereby, a sense of unity of the design can be obtained.

  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 supporting device 5 supports the electric vacuum cleaner 3. The vacuum cleaner support device 5 here is a charging station that charges a battery built in the vacuum cleaner 3. The vacuum cleaner supporting device 5 includes a suction tool mounting table 510 on which the suction tool 310 of the vacuum cleaner 3 is mounted, and a support 540 that supports the cleaner body 340 of the vacuum cleaner 3.

  2-1. Suction tool mounting table

As shown in FIG. 10, the suction device mounting table 510 has a mounting portion 511 on which the suction device 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 section 511. Front portion 521 has an insertion port 523 communicating with internal space 525. The insertion port 523 can receive the head 451 of the auxiliary dust collector 450. The mounting section 511 has one or more (seven in the example shown in FIG. 10) communication ports 513 communicating with the internal space 525. Each communication port 513 has a substantially rectangular 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 ports 323 at the bottom of the suction tool 310 when the suction tool 310 of the vacuum cleaner 3 is properly placed on the mounting portion 511. In other words, the communication port 513 is provided so that air and dust in the internal space 525 can be sucked when the vacuum cleaner 3 is turned on.
The shape of the communication port 513 is not limited to a substantially square shape. For example, the shape may be a circle, an ellipse, a triangle, or a hexagon. The number of communication ports 513 is not limited to seven. One or more than seven may be used. However, when a plurality of small holes are used instead of one large hole, the flow velocity of the fluid passing through the holes can be increased, and the residue of dust can be prevented or reduced.

  The 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 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. Dust attached to the head 451 is sucked into the vacuum cleaner 3 through the communication port 513. Thus, the head 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) protruding portions 515 that protrude into the internal space 525. Each protruding portion 515 is provided between adjacent communication ports 513. For example, the auxiliary dust collector 450 is a mop including 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 scrapes dust attached to them. Thereby, the head part 451 can be more clearly cleaned.

  The plurality of protrusions 515 are arranged in parallel with each other. Thus, the flow of air passing through the plurality of communication ports 513 can be adjusted, and as a result, dust can be efficiently sucked.

  As shown in FIG. 10, the dimension in the height direction (Z) of the insertion port 523 of the front part 521 is defined as a dimension H5. The dimension in the width direction (X) of the insertion port 523 is defined as a dimension W5. The area of the insertion port 523 is obtained by multiplying 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 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. Here, the natural state refers to a state in which the head 451 is not receiving a compressive force. The cross-sectional area of the head 451 is obtained by multiplying the dimension H6 and the dimension W6. Preferably, the insertion port 523 has an area smaller than the cross-sectional area of the head part 451. As a result, the head portion 451 fills the entire insertion opening 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 used.

As shown in FIG. 11, a dimension in the depth direction (Y) of a region in the internal space 525 where the head unit 451 can be inserted is defined as a dimension L5. As shown in FIG. 10, the dimension of the head portion 451 in the insertion direction (Y) is defined as a dimension L6. Dimension L5 is smaller than dimension L6. Thereby, even if the head part 451 is inserted to the innermost position, the state where the head part 451 fills the entire insertion opening 523 can be maintained. Therefore, the suction force of the vacuum cleaner 3 can be effectively used.
The suction tool mounting table 510 has a T-shape, and a column 540 is provided upright at an extending portion extending rearward. The internal space 525 is formed also by using the extended portion. Accordingly, the dimension of the internal space 525 in the depth direction (Y) can be sufficiently ensured while the suction tool mounting table 510 is formed slim. In addition, since the extending portion is at the center in the width direction (X), the balance of the column 540 can be improved.

  In some cases, the influence of the air leak may be negligible or small. In this case, the dimension L5 may be equal to or larger than the dimension L6. Thereby, the head part 451 can be entirely cleaned.

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

Note that 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. Thus, 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 electric vacuum cleaner 3 can be effectively used for cleaning the head portion 451.
The suction tool 310 has grooves 329 communicating with the suction port 323 on both sides 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. Thus, air leakage through the groove 329 can be prevented or reduced.

  As shown in FIG. 12, the suction port 323 at the bottom of the suction tool 310 includes a first area 325 where the rotating brush 319 exists, and a second area 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 impedance. Conversely, the second region 327 of the suction port 323 does not include the rotating brush 319 and thus has a relatively low fluid impedance. Therefore, air is mainly sucked 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 scrape out more dust than the first blade portion 517.

As described above, since a large amount of dust is scraped off below the second region 327, it is possible to prevent or reduce the unabsorbed dust in the internal space 525.
Note that the shape of the protruding portion 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 reduced from the front end to the rear end.
The positioning portion 527 is not limited to the above configuration, and may be provided all around the outer periphery of the suction tool 310. Further, instead of the protruding piece protruding from the mounting portion 511, a concave portion recessed from the mounting portion 511 that matches the shape of the suction tool 310 may be used.
Further, the insertion port 523 may be provided not on the front surface part 521 but on the side surface part.

  2-2. Prop

  The support 540 is disposed at the rear end of the suction tool mounting table 510 as shown in FIG. The support 540 has a tapered surface 541 and a concave surface 543 at the upper part. The tapered surface 541 conforms to the end surface 371 of the extension 363 of the cleaner body 340. The concave surface 543 conforms to the outer peripheral 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.

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

<Second embodiment>
The vacuum cleaner unit 1001 according to the second embodiment includes a vacuum cleaner 1003 and a vacuum cleaner support device 1005 as shown in FIG.
The electric vacuum cleaner 1003 is a so-called stick-type vacuum cleaner including a suction tool 1310, a cleaner body 340, and a handle 390 in this order.
Note that, also in the second embodiment, the width direction (X), the depth direction (Y), and the axial direction (Z) have the same definitions as in the first embodiment.
The vacuum cleaner 1003 is provided with a housing portion 410 for accommodating the auxiliary dust collecting device 450 so as to be able to be taken out from the hand tool 390 side similarly to the first embodiment. The housing section 410 is mounted on the cleaner body 340. The vacuum cleaner 1003 is charged from the vacuum cleaner supporting device 1005.
The vacuum cleaner supporting device 1005 includes a suction tool mounting table 1510 on which the suction tool 1310 of the vacuum cleaner 1003 is mounted, and a support 540 that supports the cleaner body 340 of the vacuum cleaner 3.
In the second embodiment, a part of the suction tool 1310 of the vacuum cleaner 1003 and a suction tool mounting table 1510 of the vacuum cleaner support device 1005 are different from the first embodiment. Therefore, the following description will focus on these differences. The same components as those of the first embodiment are denoted by the same reference numerals, and the description of the same components is omitted.

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

1-1. The suction port 1323 includes a first area 1325 and a second area 1327, and the suction space 1312 includes a first space 1314 existing on the back side of the first area 1325 and a second space 1327 existing on the back side of the second area 1327. It has two spaces 1316.
Note that the leading end of the leading line of the first space 1314 is an arrow in order to distinguish it from the leading lines of the first region 1325, the rotating brush 319, the inner wall 1315, and the like. Similarly, the leading end of the lead line of the second space 1316 is indicated by an arrow in order to distinguish it from the lead lines of the second region 1327 and the inner wall 1315.

As shown in FIG. 14A, the first space 1314 has a shape close to a column that is long in the width direction (X). In the first space 1314, a rotating brush 319 that is long in the width direction (X) and has the rotation axis in the width direction is accommodated.
The second space 1316 exists between the first space 1314 (the rotating brush 319) and the communication port 1317. Thus, the dust scraped out by the rotating brush 319 travels from the second space 1316 to the communication port 1317.
In other words, the suction tool 1310 has two spaces adjacent to each other in the depth direction (Y), one of which is the first space 1314 that houses the rotating brush 319, and the other is the second space that generates the swirling airflow. 1316.
The rotating brush 319 includes one or a plurality of brushes provided on a rotating shaft, for example, in a spiral shape. The brush may use a plate-like body such as a rubber material, or may use a plurality of fibrous bodies such as a resin. When a fibrous body is used, as the whole or a part of the fibrous body, a neutralizing fiber such as an organic conductive fiber in which copper sulfide is chemically bonded to an acrylic fiber or a nylon fiber may be used.

As shown in FIG. 14B, an intermediate portion of the second space 1316 in the width direction (X) 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) of the second space 1316 are tapered portions 1316b whose cross-sectional shapes are substantially the same and whose area gradually decreases toward the end.
The shape (inner wall shape) of the cross section orthogonal to the width direction (X) in the second space 1316 has a shape in which a cleaning surface side in a circular shape or a shape similar to a circular shape is chipped.

As shown in FIG. 14, the communication port 1317 is provided so as to be located in the second space 1316 on the side opposite to 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 easily 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 hinder the generation of the swirling airflow. The end 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.

An extension 1318 is provided between the first space 1314 and the second space 1316 so as to project toward the first space 1314. The overhang portion 1318 is formed of an overhang member different from the bottom cover 1313 that forms the suction space 1312.
A partition wall 1315a that partitions the first space 1314 and the second space 1316 is included in the inner wall 1315, and a projecting member is detachably attached to a cutout portion of the partition wall 1315a at an intermediate portion in the width direction (X). .

The overhang portion 1318 is provided so as to be able to contact the rotating brush 319. As shown in FIG. 15, the overhang portion 1318 overhangs in the direction opposite to the rotation direction (the direction of the arrow in the figure) of the rotating brush 319. In other words, the rotating brush 319 protrudes in the direction in which it comes into contact with the brush. As a result, dust scraped off by the rotating brush 319 around the suction port 1323 separates from the rotating brush 319. The overhang portion 1318 here is made of, for example, a rubber material. Thereby, excessive consumption of the rotating brush 319 can be suppressed. Note that the overhang portion 1318 may be made of a material capable of eliminating static electricity, so as to prevent dust from being attracted by static electricity.
The dust separated from the rotating brush 319 is sucked into the adjacent second space 1316 and then sucked into the cleaner body 340 from the communication port 1317 via the dust collecting pipe 1320.

The overhang portion 1318 is provided at an intermediate portion in the width direction (X) when the suction port 1323 is viewed from the bottom side (that is, in the state of FIG. 14B). As shown in FIG. 16B, the overhang portion 1318 is longer than the entire length of the straight portion 1316a in the second space 1316 and shorter than the entire length of the second space 1316. The total length of the overhang 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 full length of the straight portion 1316a, but is not limited thereto. Instead, the length may be adjusted to fit the entire rotating brush 319.
As shown in FIG. 14B, the length of the overhang 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. 14B, the overhang portion 1318 faces the communication port 1317 with the second space 1316 interposed therebetween. As a result, the dust scraped off by the overhang portion 1318 is efficiently sucked from the communication port 1317.
The lower end in the axial direction (Z) of the overhang portion 1318 is configured not to reach the cleaning surface as shown in FIG. 16B and FIG. As a result, dust scraped off by the overhang portion 1318 moves to the second space 1316 efficiently.
As shown in FIG. 16B, the overhang portion 1318 is located on the opposite side of the cleaning surface from the lower end (the end on the cleaning surface side) of the end of the partition wall 1315a in the width direction (X). . In other words, the lower end of the overhang portion 1318 is higher than the lower end of the partition wall 1315a that forms the tapered portion 1316b of the second space 1316 with respect to the cleaning surface. Accordingly, the hermeticity of the tapered portion 1316b of the second space 1316 can be improved, and the swirling airflow from the end in the width direction (X) to the communication port 1317 in the second space 1316 can be strengthened.
The lower end of the overhang 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 includes a communication side pipe 1322 disposed facing the second space 1316 and a main body side pipe disposed on the cleaner main body 340 side. A connection pipe 1326 for rotatably connecting the main body side pipe 1324 to the communication side pipe 1322 with an X axis parallel to the width direction (X) and a Y axis parallel to the depth direction (Y) as a rotation axis; Is provided. The connecting pipe 1326 includes 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 in which the opening is 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 part with the cleaner main body 340 side, and is also electrically connected so that the rotating brush 319 is rotationally driven by a driving unit (not shown).
The connection pipe 1326 is connected to the communication pipe 1322 so as to be rotatable around the Y axis. The main body side pipe 1324 is connected to the connection pipe 1326 so as to be rotatable around the X axis. The dust collection pipe 1320 has a restriction release structure that restricts the connection pipe 1326 from rotating around the Y axis with respect to the communication side pipe 1322, and releases the rotation restriction.

(2) Communication side pipe and connection pipe The connection between the communication side pipe 1322 and the connection pipe 1326 is performed by connecting the lower cylindrical portion 1322a of the downstream side of the communication side pipe 1322 as shown in FIG. Is fitted to the cylindrical fitting portion 1328a at the upstream end of the housing, and in this state, it is fixed by the "C" -shaped fixture 1331.
Here, since the cylindrical portion 1322a 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 circumferential groove 1322b extending in the circumferential direction in the cylindrical portion 1322a, and the connecting pipe 1326 has through holes 1328b, 1328c (FIG. 18) in the fitting portion 1328a at positions corresponding to the circumferential groove 1322b of the cylindrical portion 1322a. Reference). The protrusions 1331a and 1331b of the “C” -shaped fixture 1331 are inserted through the through holes 1328b and 1328c of the connecting lower pipe 1328 and fit into the circumferential groove 1322b of the communication side pipe 1322. This can prevent the connection pipe 1326 (connection lower pipe 1328) from coming off from the communication side pipe 1322.

This will be described in detail.
The fitting part 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 protrusions 1331a and 1331b of the fixture 1331. The “C” -shaped fixture 1331 has an arc shape longer than a semicircle, the protrusion 1331a is located substantially at the center of the arc, and the protrusions 1331b are located at both ends of the arc. This makes it difficult for the fixture 1331 to come off the lower connection pipe 1328. Note that the fixture 1331 is fixed to the connection pipe 1326, and does not rotate with the fixture 1331 alone.

As shown in FIG. 19, the restriction release structure includes 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 fixing device 1331). Be composed.
The engaged portion 1322c has a recess 1322d that is recessed in a direction parallel to the cylinder axis on the side opposite to the side where the fixture 1331 exists. The engagement portion 1331c has a protruding portion 1331d that is on the communication pipe 1322 side and protrudes in a direction parallel to the cylinder axis. When the convex portion 1331d engages (fits) with the concave portion 1332d, the rotation of the connection pipe 1326 with respect to the communication side pipe 1322 is restricted.
The concave portion 1322d and the convex portion 1331d have a circular arc shape when viewed from a direction perpendicular to the engagement direction (FIG. 19C). This makes it possible to smoothly release the rotation restriction.

When the restriction release structure is viewed from a direction orthogonal to the engagement direction (FIG. 19C), the engaged portion 1322c is inclined such that it becomes farther from the fixing member 1331 as it moves away from the concave portion 1322d in the circumferential direction. A portion 1322e is provided on both sides of the concave portion 1322d. Accordingly, even when the engaging portion 1331c (the protruding portion 1331d) is at a position circumferentially separated from the engaged portion 1322c (in a state where rotation is not restricted), the protruding portion 1331d is rotated by the connection pipe 1326. It smoothly engages (fits) with the concave portion 1322d.
The engaged portion 1322c is provided on an outer cylindrical portion 1322f coaxial with the cylindrical portion 1322a as shown in FIGS. 19A and 19B, and is engaged when the lower coupling pipe 1328 rotates. The engaged portion 1322c is located on the track of the portion 1331c.

The fixture 1331 has an engaging portion 1331c so as to be elastically deformable in a direction parallel to the cylinder axis. More specifically, the fixture 1331 has a U-shaped portion 1331f that projects in a reverse “U” shape radially outward from a “C” -shaped main body portion 1331e, and engages with the U-shaped portion 1331f. A joint 1331c is provided.
Accordingly, 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 engagement of the convex portion 1331d with the concave portion 1322d or the concave portion is performed. Disengagement from 1322d can be performed smoothly.

Since the fixture 1331 regulates the communication side pipe 1322 from coming off the connection pipe 1326, it has 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 and the U-shaped portion 1331f in the engaging direction (here, the cylindrical portion 1322a of the communication side pipe 1322) with an appropriate load. Elastic deformation in the direction parallel to the cylinder axis direction), making it difficult to disengage the engaged state between the convex portion 1331d and the concave portion 1322d.
As described above, 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 degree of engagement or engagement between the convex portion 1331d and the concave portion 1322d can be increased. Adjustment degree can be adjusted. The portion where the convex portion 1331d is provided may have a shape other than the U-shaped portion 1331f, such as an L-shaped portion or an O-shaped portion.

  In addition, a driving unit (not shown) for rotating and driving the rotating brush 319 is provided in the suction tool 1310. In general, a communication side pipe 1322 and the like are provided at a central portion of the suction tool 1310 in the width direction (X), and the driving unit is disposed so as to be shifted from the center of the suction tool 1310 in the width direction to one side in the width direction. ing. For this reason, when the suction tool 1310 is lifted during use, a load is generated in which the communication side pipe 1322 tries to rotate with respect to the connection pipe 13326 under 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 rotation load, it is possible to eliminate wobble when the suction tool 1310 is lifted.

2. Vacuum cleaner support device The vacuum cleaner support device 1005 supports the vacuum cleaner 1003. The vacuum cleaner supporting device 1005 here is a charging station that charges a battery built in the vacuum cleaner 1003.

The base portion 1530 has a recessed portion 1533 that is recessed into the installation surface side on the surface on the placement portion 511 side, and a static elimination member, here, an iron plate 1534, is disposed in the recessed portion 1533. The base portion 1530 has a guide portion 1538 so that the head portion 451 of the auxiliary dust collector 450 can be smoothly inserted into the insertion opening 523. The guide portion 1538 is formed by a downwardly inclined surface.
The iron plate 1534 has a function of removing charges that have been charged on the head portion 451 of the auxiliary dust collector 450. The iron plate 1534 is provided at a position close to the installation surface, and has a function of supporting the vacuum cleaner 1003 in a stable state. The iron plate 1534 is larger than the dimension of the insertion port 523 in the width direction (X), and extends to the opposite side of the inner space 525 from the side wall 525a forming the inner 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 section 1535 behind the mounting section 511 when the suction tool mounting table 1510 is viewed from above. Here, the nozzle holding portion 1535 includes a protruding portion 1536 protruding from the base portion 1530, and a cylindrical portion 1537 extending upward from the protruding portion 1536. The gap nozzle 1007 is detachably supported by its tubular portion 1071 fitted outside the tubular portion 1537.
