[0010] Hereinafter, a vacuum cleaner system S and an electric vacuum cleaner 1 according to one embodiment of the present invention will be described in detail with reference to the drawings. In the following description, unless otherwise specified, the positional relationships in the up-down direction, width direction, etc. will be described based on the state in which the vacuum cleaner system S, the electric vacuum cleaner 1, and the vacuum cleaner main body 10 are erected as shown in Figs. 1 to 7.

[0011] 1 and 3, the vacuum cleaner system S and the vacuum cleaner 1 are devices that share a vacuum cleaner main body 10 as a common component. That is, the vacuum cleaner main body 10 is positioned as a common component that can be used in both the vacuum cleaner system S and the vacuum cleaner 1. In the following explanation, the configuration of the vacuum cleaner main body 10, which is a common component, will first be explained, and then the configurations of the vacuum cleaner system S and the vacuum cleaner 1 will be explained.

[0012] <About the vacuum cleaner body 10> The vacuum cleaner body 10 is a part of the electric vacuum cleaner 1 that exerts a suction force to perform a function of collecting dust. Specifically, as shown in Fig. 6 and Fig. 7, the vacuum cleaner body 10 has an electric blower 40 for sucking air and generating an airflow, a dust collecting section 50, and other parts built in a case (vacuum cleaner housing 20) that forms a housing. Also, as shown in Fig. 2 and Fig. 5, the vacuum cleaner body 10 has a rod-shaped gripping section 14 at one end side in the longitudinal direction (axial direction) of the vacuum cleaner housing 20, and a first suction port 62a of a nozzle 62 at the other end side.

[0013] The cleaner housing 20 is configured by connecting a first cleaner housing section 20a on the grip section 14 side and a second cleaner housing section 20b on the first suction port 62a side in the axial direction. As shown in Fig. 7, the first cleaner housing section 20a is provided with a battery housing section 22, a cleaner side engagement section 24, a board housing section 26, a blower housing section 28, etc. The second cleaner housing section 20b is provided with a dust collection section 50 and a suction port configuration section 60.

[0014] The battery accommodating section 22 accommodates a battery 22x. The cleaner-side engaging section 24 is provided on the cleaner body 10 side to constitute an engaging structure (cleaner body engaging structure 142) for engaging the cleaner body 10 with the support 100. The board accommodating section 26 accommodates a board 26x. The blower accommodating section 28 accommodates an electric blower 40.

[0015] The electric blower 40 is for generating an airflow for sucking in dust. The electric blower 40 has an intake section 40a and an exhaust section 40b, and can generate an airflow from the intake section 40a to the exhaust section 40b by supplying power. The electric blower 40 is disposed inside the vacuum cleaner housing 20, between the board housing section 26 and the dust collection section 50. The electric blower 40 is disposed such that the intake section 40a faces the dust collection section 50.

[0016] 7, the dust collection unit 50 is provided in the second cleaner housing portion 20b of the cleaner housing 20. The dust collection unit 50 is a portion that collects dust sucked in from the first suction port 62a. The dust collection unit 50 has a dust cup 52, a first filter portion 54, and a second filter portion 56.

[0017] The dust cup 52 is hollow and has a cup-like shape. The dust cup 52 may be formed by providing a separate cylinder inside the second vacuum cleaner housing part 20b, but in this embodiment, the cylinder forming the second vacuum cleaner housing part 20b is used as the dust cup 52. The dust cup 52 is detachably connected to the housing (first vacuum cleaner housing part 20a) constituting the vacuum cleaner main body 10. The first filter part 54 is accommodated inside the dust cup 52 described above. The first filter part 54 is a bottomed cylindrical member with an open upper end and a closed lower end, and has a plurality of air holes 54a on the circumferential surface. The second filter part 56 is disposed inside the first filter part 54.

[0018] 6 and 7, the suction port forming part 60 is provided at the end part on the second cleaner housing part 20b side. The suction port forming part 60 has a nozzle 62 and a surrounding wall 64.

[0019] The nozzle 62 is cylindrical and has a first suction port 62a at one end for sucking dust. The first suction port 62a is an opening provided in the vacuum cleaner body 10 for sucking dust into the dust collecting section 50. The first suction port 62a has substantially the same opening shape and size as the extension tube 90 constituting the vacuum cleaner system S described later in detail and the second suction port 134 provided in the support body 100 constituting the vacuum cleaner 1.

[0020] The surrounding wall 64 is a wall-like portion formed to surround the outer periphery of the first suction port 62a. The surrounding wall 64 has an end portion at a position where the tip of the first suction port 62a is set back in the axial direction of the vacuum cleaner body 10 from the tip of the surrounding wall 64. That is, in the portion where the surrounding wall 64 is provided, the tip portion of the nozzle 62 on the first suction port 62a side protrudes in the axial direction of the vacuum cleaner body 10 beyond the surrounding wall 64. The end portion of the surrounding wall 64 abuts against the upper surface of the receiving portion 82.

[0021] About the Vacuum Cleaner System S The vacuum cleaner system S includes the above-mentioned vacuum cleaner body 10 and a support device 70. The vacuum cleaner system S can be used in two usage patterns: one in which the vacuum cleaner body 10 is supported by the support device 70 as shown in Fig. 1, and the other in which the vacuum cleaner body 10 is moved away from the support device 70 and used as shown in Fig. 6. The vacuum cleaner system S can be used not only by itself with the vacuum cleaner body 10 moved away from the support device 70, but also in the form of a stick-type vacuum cleaner (second mode) by connecting an extension tube 90 and a suction tool 92 to the nozzle 62 of the vacuum cleaner body 10 as shown in Figs. 2 and 4.

[0022] 1 and other figures, the support device 70 functions as a stand for supporting the vacuum cleaner body 10, and preferably has a charging mechanism. The support device 70 is provided with a support device main body 72, a space forming section 74, and a storage section 76.

[0023] The support device body 72 is a part that supports the vacuum cleaner body 10. The support device body 72 has a support column part 78 and a base part 80. The support column part 78 is a column-shaped part that is erected so as to be inclined from the front side to the rear side so that the vacuum cleaner body 10 can be supported in an oblique posture. Therefore, by making the rear side of the vacuum cleaner body 10 come into surface contact with the front side of the support column part 78 and leaning the vacuum cleaner body 10 against the support column part 78, the vacuum cleaner body 10 can be supported from the rear side in a state inclined from the front side to the rear side. The support device body 72 has a length that does not exceed the length from the first suction port 62a of the vacuum cleaner body 10 to the end of the grip part 14. Therefore, when the vacuum cleaner body 10 is leaned against the support device body 72, the part of the vacuum cleaner body 10 on the grip part 14 side protrudes upward from the support device body 72.

[0024] The base portion 80 is located on the base end side (lower end side) of the support portion 78. The base portion 80 is a portion that serves as a base for the vacuum cleaner body 10 supported by the support portion 78. The base portion 80 has a receiving portion 82 and a support portion 84. As shown in FIG. 1, FIG. 8, FIG. 9, etc., the receiving portion 82 is provided at a position where the nozzle 62 arrives when the vacuum cleaner body 10 is leaned against the support device body 72 with the nozzle 62 facing downward. The receiving portion 82 has a receiving port that receives the suction port forming portion 60. The receiving portion 82 is opened so that the cylinder that constitutes the suction port forming portion 60 can be inserted with almost no gap. In this embodiment, the nozzle 62 of the vacuum cleaner body 10 can be inserted into the receiving port of the receiving portion 82, and the outer peripheral surface (an example of a peripheral wall) of the nozzle 62 is covered by the receiving portion 82. Furthermore, a first airtight member 82a may be provided between the receiving portion 82 and the outer peripheral surface of the nozzle 62, or the first airtight member 82a may be provided between the tip end of the peripheral wall 64 and an upper surface portion where the receiving port of the receiving portion 82 is formed. The receiving portion 82 may cover the outer peripheral surface of the peripheral wall 64 (an example of a peripheral wall).

[0025] The support portion 84 is a portion that supports the nozzle 62 inserted into the receiving portion 82 on the bottom side of the area surrounded by the receiving portion 82. The support portion 84 is provided with a protruding stopper portion 84a that can abut against the tip of the nozzle 62 so that the nozzle 62 inserted into the receiving portion 82 does not shift position to the front side. The support portion 84 also has an opening 84b that opens into a space 74a formed on the lower side of the support portion 84 by a space forming portion 74 described later. Therefore, when the nozzle 62 is inserted into the receiving portion 82 and the vacuum cleaner body 10 is supported by the support device body 72, the first suction port 62a of the nozzle 62 can be communicated with the space 74a formed by the space forming portion 74 via the opening 84b. Therefore, when the nozzle 62 is inserted into the receiving portion 82 and supported by the support portion 84, the electric blower 40 of the vacuum cleaner body 10 is operated to generate a suction force in a direction from the space 74a toward the vacuum cleaner body 10 through the opening 84b. In addition, a second airtight member 82b may be provided at a position between the support portion 84 and the tip of the nozzle 62 when the nozzle 62 is inserted into the receiving portion 82. Note that, in this embodiment, three support portions 84 are provided to form four opening portions 84b, but it is sufficient to provide one or more support portions 84 to form two or more opening portions 84b.

[0026] As shown in FIG. 8 to FIG. 11, the space forming portion 74 is a portion that forms a hollow space 74a below the support portion 84. The space 74a formed by the space forming portion 74 communicates with the receiving portion 82 through the opening 84b described above. In addition, the space forming portion 74 has the space 74a open to the outside through the communication port 74b provided on the front side. This allows the auxiliary dust collector (head portion described later) to be inserted and removed from the space 74a through the communication port 74b, or the auxiliary dust collector to be used to bring dust close to the communication port 74b, thereby introducing (sucking) the dust into the space 74a. In addition, a static electricity removing plate 74c is provided on the bottom surface of the space forming portion 74. This allows the auxiliary dust collector to be inserted and removed through the communication port 74b, thereby suppressing static electricity charging of the auxiliary dust collector, and dust attached to the auxiliary dust collector can be separated in the space 74a. 9 and 11, the comb teeth 74d are provided on the back side of the support portion 84, but the position is not limited to this as long as they protrude into the space 74a. This allows dust attached to the auxiliary dust collector (head portion described later) to be scraped off and removed by the comb teeth 74d when the auxiliary dust collector is inserted or removed through the communication opening 74b. The auxiliary dust collector is, for example, a handy mop, has a handle portion and a head portion, and can collect dust with the head portion. The support device 70 has been described as having both the static elimination plate 74c and the comb teeth 74d, but may have at least one of them.

[0027] As shown in FIG. 1 and other figures, the storage section 76 is provided on the rear side of the support column 78. The storage section 76 is provided to utilize the area (space) formed below the support column 78, which is inclined from the front side to the rear side of the support device 70, for storing an auxiliary dust collector or an attachment. In this embodiment, a mop storage section 76a for inserting and storing a mop, which is the auxiliary dust collector, is provided in the storage section 76. In addition, an attachment holding section 94 capable of holding an extension tube 90 and a suction tool 92 connected to the nozzle 62 in an upright state is provided on the lateral side of the receiving section 82 and the support column 78. The attachment holding part 94 that holds the suction tool 92 can hold the short-side sidewall of the suction tool 92, whose joint part (joint pipe) can rotate relative to the suction tool main body in the longitudinal and short-side directions, and the short-side sidewall of the suction tool main body of the suction tool 92 is sandwiched between two protruding walls erected from the base part 80, so that the suction tool 92 fits within the range of the base part 80. In addition, since the joint part of the suction tool 92 can rotate left and right relative to the suction tool main body, the joint part is aligned in the direction of gravity due to the rotation, so that it can be stored more compactly. In this way, the vacuum cleaner main body 10 supported by the support part 78 in a top view, and the suction tool 92 and the attachment held by the attachment holding part 94 fit within the base part 80, so that the overall size can be reduced.

[0028] <About Vacuum Cleaner 1> As shown in Figs. 3, 5, and 12, the vacuum cleaner 1 is a stick-shaped (vertical) vacuum cleaner. The vacuum cleaner 1 may be a vacuum cleaner that obtains power from an external power source via a power cord, but in this embodiment, it is a rechargeable vacuum cleaner. The vacuum cleaner 1 includes a vacuum cleaner body 10, a support 100, and a suction section 200. The vacuum cleaner body 10 is detachable from the support 100, and the vacuum cleaner 1 can be used in either a mode in which the vacuum cleaner body 10 is used alone, or a mode in which the vacuum cleaner body 10 is used in a state in which it is attached to the support (attached state) (first mode). The vacuum cleaner 1 can be charged by placing it on a stand 300.

[0029] The support 100 supports the above-mentioned vacuum cleaner body 10. The support 100 is configured such that a storage section 120, a lower connection section 130, an upper connection section 140, and a handle section 150 are provided on a support housing 110 formed so as to extend in the vertical direction when the vacuum cleaner 1 is placed upright.

[0030] The storage section 120 is provided in the middle of the support housing 110 in the longitudinal direction. The storage section 120 is a portion that detachably stores the vacuum cleaner body 10. The storage section 120 has a size large enough to accommodate the vacuum cleaner body 10 in the vertical direction.

[0031] The lower connection part 130 is provided on the lower end side of the storage part 120. The lower connection part 130 is a part to which the suction port forming part 60 of the vacuum cleaner body 10 and the suction part 200 described later in detail are connected. The lower connection part 130 has a lower communication port 132 provided so as to open at the lower end part of the storage part 120. The lower communication port 132 opens so as to communicate with the first suction port 62a of the nozzle 62 provided in the suction port forming part 60 when the vacuum cleaner body 10 is stored in the storage part 120 in a posture in which the suction port forming part 60 faces downward and the grip part 14 faces upward. The tubular part constituting the first suction port 62a is inserted into the tubular communication part constituting the lower communication port 132, thereby improving airtightness.

[0032] The upper connection part 140 is provided on the upper end side of the storage part 120. The upper connection part 140 is engaged with the cleaner-side engagement part 24 provided on the grip part 14 side of the vacuum cleaner body 10 described above, thereby making it possible to fix the vacuum cleaner body 10 on the grip part 14 side.

[0033] The handle portion 150 is for a user to grasp when using the electric vacuum cleaner 1 in a mounted state in which the vacuum cleaner body 10 is mounted on the support 100. The handle portion 150 is a portion provided so as to continue in the longitudinal direction (up-down direction) of the vacuum cleaner body 10 at a position above the storage portion 120 of the support 100. The handle portion 150 has a straight portion 152 and a grip 154. The straight portion 152 is a portion formed so as to extend linearly along the central axis direction of the electric blower 40 built into the vacuum cleaner body 10. The grip 154 ​​is a portion continuing from the straight portion 152, extends in a direction intersecting with the central axis direction of the electric blower 40, and is a portion that can be grasped by the user. It is also preferable that the intersection of the front surface of the grip 154 ​​and the central axis of the electric blower 40 is included in the user's gripping area. This can improve operability.

[0034] When the vacuum cleaner body 10 is accommodated and attached to the accommodation section 120 of the support 100 described above, the front side (front surface side) of the vacuum cleaner body 10 is exposed, and the rear side (rear surface side) is covered by the support 100. That is, when the direction along the axial direction of the electric blower 40 of the vacuum cleaner body 10 is defined as a first direction, and the direction perpendicular to the first direction is defined as a second direction, the support 100 can be attached to the accommodation section 120 in a state in which the front side, which is one side of the second direction of the vacuum cleaner body 10, is exposed, and the rear side, which is the other side of the second direction, is covered, as the attachment state. In the attachment state in which the vacuum cleaner body 10 is attached to the support 100, the vacuum cleaner body 10 does not substantially protrude from the front side (front surface side) of the support 100. Specifically, in the electric vacuum cleaner 1 of this embodiment, in the attachment state in which the vacuum cleaner body 10 is attached to the support 100, the protrusion amount of the vacuum cleaner body 10 is within a range of 0 mm to 20 mm.

[0035] In addition, in a mounted state in which the vacuum cleaner body 10 is mounted on the support body 100, when viewed from the central axis direction of the handle portion 150, the central axis of the electric blower 40 is located within the width of the straight portion 152 in a direction perpendicular to the central axis direction. Furthermore, in the mounted state, the vacuum cleaner body 10 is mounted on the support body 100 such that, when viewed from the central axis direction of the handle portion 150, the central axis of the electric blower 40 is located within the opening width of the first suction port 62a of the vacuum cleaner body 10 and the lower communication port 132 on the support body 100 side.

[0036] As shown in FIG. 3, FIG. 5, and FIG. 12, the suction unit 200 includes a suction unit main body 202 and a joint part 204. As shown in FIG. 12, the suction unit 200 includes, inside the suction unit main body 202, a cleaning body 206, a drive mechanism (not shown) for driving the cleaning body 206, and other components. The suction unit main body 202 is a part that is placed on the floor during cleaning, and has a shape that is long in the left-right direction compared to the front-rear direction in which the user operates the cleaning unit during cleaning. Inside the suction unit main body 202, a suction space is formed with the floor side as an open end, for sucking in air and dust from the outside. The joint part 204 is attached to the suction unit main body 202 so as to be rotatable within a predetermined rotation range (front-rear and left-right directions). The joint part 204 is a part that is connected to the second suction port 134 provided in the lower connection part 130 of the support 100 described above. The joint portion 204 is cylindrical, and its internal space communicates with the suction space.

[0037] The stand 300 can be used to place the vacuum cleaner 1 when the vacuum cleaner 1 is not in use. By placing the vacuum cleaner 1 on the stand 300, the battery 22x built into the vacuum cleaner body 10 can be charged.

[0038] The cleaner system S according to the embodiment described above has the configurations described below in (1-1) to (1-11), and thereby provides the following effects.

[0039] Conventionally, there has been provided a vacuum cleaner as disclosed in Japanese Patent Laid-Open Publication No. 50-119460. The vacuum cleaner of Patent Document 1 is designed to be stored in a storage box after cleaning is completed. By adopting such a configuration, the vacuum cleaner of Patent Document 1 solves the problem of storage space and also aims to eliminate the trouble of dust removal by automatically removing dust from a filter provided in the vacuum cleaner body for a predetermined period of time. Here, the electric vacuum cleaner of Patent Document 1 mentioned above has the problem that although the filter installed inside the vacuum cleaner body can remove dust when the vacuum cleaner body is stored in the storage box, the vacuum cleaner body cannot collect dust. SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a vacuum cleaner system that allows cleaning to be performed using the vacuum cleaner main body even when the vacuum cleaner main body is supported by a support device. (1-1) The vacuum cleaner system S of the present embodiment described above comprises a vacuum cleaner body 10 that sucks in dust from a first suction port 62a of an suction port forming part 60 by suction from an electric blower 40, and a support device 70 that supports the vacuum cleaner body 10, the support device 70 having a space forming part 74 that forms a hollow space 74a, a communication port 74b that connects the inside and outside of the space 74a, and an opening 84b that connects the first suction port 62a to the space 74a when the suction port forming part 60 is supported by the support device 70.

[0040] The vacuum cleaner system S of this embodiment includes a vacuum cleaner body 10 and a support device 70, and the vacuum cleaner body 10 can be supported by the support device 70. The vacuum cleaner system S is configured to have a hollow space 74a formed by the space forming part 74, and an opening 84b for communicating the first suction port 62a of the suction port forming part 60 of the vacuum cleaner body 10 supported by the support device 70 with the space 74a. Furthermore, the space 74a is configured to communicate with the outside through the communication opening 74b. Because of this configuration, the vacuum cleaner system S can create a negative pressure in the space 74a of the support device 70 through the opening 84b communicating with the first suction port 62a of the suction port forming part 60 and suck dust through the communication opening 74b by operating the vacuum cleaner body 10 in a state in which the vacuum cleaner body 10 is supported by the support device 70. Therefore, according to the vacuum cleaner system S, even when the vacuum cleaner body 10 is supported by the support device 70, cleaning can be performed using the vacuum cleaner body 10.

[0041] (1-2) The vacuum cleaner system S of this embodiment described above is characterized in that an auxiliary dust collector can be inserted through the communication opening 74b.

[0042] With this configuration, the vacuum cleaner system S can clean the auxiliary dust collector by operating the electric blower 40 while the vacuum cleaner body 10 is supported on the support device 70 and moving the auxiliary dust collector in and out of the space 74a through the communication port 74b.

[0043] (1-3) In the vacuum cleaner system S of the present embodiment described above, the support device 70 is characterized in that it has a receiving portion 82 that receives the suction port component 60, and the receiving portion 82 covers the peripheral wall of the suction port component 60.

[0044] Because of this configuration, the vacuum cleaner system S can make the suction port forming part 60 and the receiving part 82 airtight when the suction port forming part 60 is received in the receiving part 82.

[0045] (1-4) The vacuum cleaner system S of the present embodiment described above is characterized in that the first airtight member 82a is disposed between the support device 70 and the suction port configuration portion 60.

[0046] Because of this configuration, when the vacuum cleaner system S is in a state in which the suction port component 60 is supported on the support device 70, the suction port component 60 and the support part 84 can be airtightly connected via the first airtight member 82a.

[0047] (1-5) The vacuum cleaner system S of the present embodiment described above is characterized in that the second airtight member 82b is disposed between the receiving portion 82 and the suction port configuration portion 60.

[0048] Because of this configuration, when the vacuum cleaner system S has the suction port component 60 received in the receiving part 82, the suction port component 60 and the receiving part 82 can be made airtight via the second airtight member 82b.

[0049] (1-6) The vacuum cleaner system S of the present embodiment described above may be characterized in that the support device 70 includes a support column 78 that supports the vacuum cleaner body 10 in an oblique position.

[0050] With this configuration, the vacuum cleaner system S can support the vacuum cleaner body 10 in a state where it is leaned against the support column 78.

[0051] (1-7) The vacuum cleaner system S of the present embodiment described above is preferably characterized in that the support device 70 has a support portion 78 that supports the vacuum cleaner body 10 in a position tilted from the front side to the rear side, a base portion 80 that serves as a base for the vacuum cleaner body 10 supported by the support portion 78, and a storage portion 76, rearward of the support portion 78, for storing an auxiliary dust collector or an attachment.

[0052] Because of this configuration, the vacuum cleaner system S can utilize the space formed on the rear side of the support pillar 78 as the storage section 76.

[0053] (1-8) In the vacuum cleaner system S of the present embodiment described above, the vacuum cleaner body 10 has a first suction port 62a on one side in the axial direction and a grip portion 14 on the other side, and the support portion 78 is preferably characterized in that its length does not exceed the length from the first suction port 62a to the grip portion 14.

[0054] Because of this configuration, when the vacuum cleaner body 10 is leaned against the support column 78, the vacuum cleaner system S can have the portion on the grip part 14 side protruding upward beyond the support column 78. This allows the grip part 14 to be smoothly gripped when the vacuum cleaner body 10 is detached from the support device 70 for use.

[0055] Here, in the prior art, as disclosed in JP-A-2-177922, a hose attachment device that can be suitably used when connecting a suction hose and a hose joint in a freely rotatable manner is disclosed. As disclosed in the patent document, if parts compatible with multiple attachments are used, multiple attachments and a hose may be easily connected. However, there is a problem in that it is difficult to make it possible to switch the usage form of the vacuum cleaner body using compatible parts. Therefore, the present invention aims to realize a vacuum cleaner body that can be used by switching the usage form of the vacuum cleaner body.

[0056] (2-1) In order to solve such problems, the vacuum cleaner body 10 of the above-mentioned embodiment comprises an electric blower 40, a nozzle 62 having a first suction port 62a for sucking in dust by the suction of the electric blower 40, and a dust collection section 50 for collecting the dust sucked through the first suction port 62a, and is usable in both a first mode in which it is attached to the storage section 120 of a support body 100 having a handle section 150, and a second mode in which it is connected to a suction tool 92 via an extension tube 90.

[0057] The vacuum cleaner body 10 of this embodiment can be used not only in a first mode in which it is attached to the storage part 120 of the support 100 having the handle part 150, but also in a second mode in which it is connected to the suction tool 92 via the extension tube 90. Therefore, the vacuum cleaner body 10 of this embodiment can be used by switching the usage form of the vacuum cleaner body 10.

[0058] (2-2) The vacuum cleaner body 10 of the present embodiment described above is preferably characterized in that the support 100 has a lower connection portion 130 in the storage portion 120 that communicates with the first suction port 62a, and the nozzle 62 is airtightly connected to the lower connection portion 130 in the first aspect, and is connected to the extension tube 90 so that the outer surface is covered by the extension tube 90 in the second aspect.

[0059] According to this configuration, whether the first or second embodiment is used, airtightness is ensured at the connection portion of the nozzle 62, and a decrease in dust collection capacity can be suppressed.

[0060] (2-3) The vacuum cleaner body 10 of the present embodiment described above is preferably characterized in that the handle portion 150 has a straight portion 152 that extends linearly along the central axis of the electric blower 40, and when viewed from the axial direction of the central axis, the central axis of the electric blower 40 is located within the width of the straight portion 152 in a direction perpendicular to the central axis direction.

[0061] According to this configuration, in the first mode in which vacuum cleaner body 10 is attached to support 100, electric blower 40 can be disposed closer to the inside of accommodating section 120 to a position where the central axis of electric blower 40 fits within the width of straight portion 152 in a direction perpendicular to the central axis direction. This makes it possible to prevent vacuum cleaner body 10 from protruding from support 100 in the mounted state in which vacuum cleaner body 10 is accommodated in accommodating section 120 provided in support 100, thereby achieving a compact configuration for electric vacuum cleaner 1 in which vacuum cleaner body 10 is attached to support 100.

[0062] (2-4) The vacuum cleaner body 10 of the present embodiment described above may be characterized in that, when viewed from the axial direction of the central axis of the electric blower 40, the central axis of the electric blower 40 is located within the opening width of the first suction port 62a and the lower communication port 132 of the lower connection portion 130.

[0063] According to this configuration, in the first mode in which vacuum cleaner body 10 is attached to support body 100, electric blower 40 can be disposed closer to the inside of accommodating section 120 to a position where the central axis of electric blower 40 fits within the opening width of first suction port 62a and lower communication port 132. As a result, in the first mode, in the mounted state in which vacuum cleaner body 10 is accommodated in accommodating section 120 provided in support body 100, vacuum cleaner body 10 is prevented from protruding from support body 100, and the electric vacuum cleaner 1 can be configured compactly.

[0064] (2-5) The vacuum cleaner body 10 of the present embodiment described above may be characterized in that the handle portion 150 extends in a direction intersecting the axial direction of the central axis of the electric blower 40 and has a grip 154 ​​that can be grasped.

[0065] According to this configuration, in the first mode in which the vacuum cleaner body 10 is attached to the support 100, the user can easily handle the vacuum cleaner 1 by gripping the grip 154. In the present embodiment, an example is shown in which the handle portion 150 is provided with the grip 154 ​​extending in a direction intersecting with the central axis direction of the electric blower 40, but the present invention is not limited to this, and the handle portion 150 may be a rod-like one that extends linearly without the grip 154. The handle portion 150 may also be a one that extends in a loop shape from the front side (front side) to the rear side (back side). In the case of such a configuration, it is preferable that the handle portion 150 of the support 100 and the central axis of the electric blower 40 intersect with each other, and the central axis of the electric blower 40 is contained within the range of the thickness of the handle portion 150.

[0066] Here, in the prior art, it is known that an attachment is stored in a support device by inserting an opening of the attachment into a protrusion erected on the base of the support device. A suction tool is sometimes stored as one of the attachments, but when a suction tool whose joint part (joint pipe) is rotatable relative to the suction tool body is supported by the support device in the above-mentioned manner, the suction tool body rotates, resulting in a problem of unstable support. Therefore, the present invention has an object to realize a vacuum cleaner system capable of stably supporting a suction tool.

[0067] (3-1) In order to solve such problems, the vacuum cleaner system S of the present embodiment described above includes a vacuum cleaner body 10 and a support device 70 that supports the vacuum cleaner body 10, the support device 70 having an attachment holding part 94 capable of supporting a suction tool 92 whose joint part is rotatable relative to the suction tool body, and the attachment holding part 94 supports a side wall in the short direction of the suction tool 92. With this configuration, it is possible to stably support the suction tool.

[0068] (3-2) The vacuum cleaner system S of the present embodiment described above may be characterized in that, when the suction tool 92 is held by the attachment holding portion 94, the joint portion rotates so that the communication port at the end of the joint portion faces the direction of gravity.

[0069] (3-3) The vacuum cleaner system S of the present embodiment described above may be characterized in that the extension tube is held by the attachment holding portion on one side in the left-right direction with the vacuum cleaner main body 10 supported by the support device 70 as a reference, and the suction tool is held by the attachment holding portion on the other side in the left-right direction.

[0070] The present invention is not limited to the configurations described in the above-mentioned embodiments, and appropriate design modifications and the like are possible within the scope of the technical idea of ​​the present invention. The components of the above-mentioned embodiments and modifications may be arbitrarily selected and combined. Any component of each embodiment or modification may be arbitrarily combined with any component described in the means for solving the invention, the mode for carrying out the invention, etc., or any component that embodies any component described in the means for solving the invention, the mode for carrying out the invention, etc. The present invention also intends to obtain rights to these in this application or in a divisional application based on this application.
