[0069] S: Electric vacuum cleaner system DETAILED DESCRIPTION

[0070] <<First Implementation Method>>

[0071] Hereinafter, an electric vacuum cleaner 1 according to a first embodiment of the present invention and an electric vacuum cleaner system S having the electric vacuum cleaner 1 will be described in detail with reference to the accompanying drawings. In addition, in the following description, after the overall structure of the electric vacuum cleaner 1 is briefly described, the main parts are described in further detail. In addition, in the following description, unless otherwise specified, the positional relationship in the up-down direction, the front-back direction, the left-right direction (width direction), etc. is as follows: Figure 1 The description will be made based on the state in which the electric vacuum cleaner 1 is installed upright.

[0072] like Figure 1 , Figure 2 As shown in FIG. 1 , the electric vacuum cleaner 1 is a vacuum cleaner having a stick-shaped (vertical) appearance. The electric vacuum cleaner 1 may be, for example, a rechargeable type, or may obtain power from an external power source via a power cord. Figure 1 , Figure 2 As shown, the electric vacuum cleaner 1 includes a main body 10, a handle 20, a first dust collecting unit 50 (dust collecting unit), an extension pipe 180, and a suction tool 190. In addition, the electric vacuum cleaner system S can be arranged in a state of standing on the bracket 200 when the suction tool 190 is arranged on the bracket 200.

[0073] The main body 10 is a part that constitutes the main body of the electric vacuum cleaner 1 and performs the function of generating suction to collect dust. Figure 2 As shown, the main body 10 includes a drive circuit and other components inside a main body casing 12 constituting a housing. The drive circuit drives a first electric blower 14 (electric blower) for sucking air to generate airflow and other electronic components.

[0074] The main body 10 includes a battery storage portion 15 for storing a battery 15a. The battery 15a (battery storage portion 15) is provided in a region of the main body 10 further rearward than the position where the handle 20 is provided.

[0075] A suction port 38y for connecting the extension tube 180 or the suction piece 190 is provided at the lower end side of the main body 10. The main body 10 has a tube portion 38x, which is provided with a suction port 38y at one end, and a discharge port connected to the inlet of the first dust collecting portion 50 is formed on the tube portion 38x. The suction port 38y is provided on the lower side of the main body 10 in the up-down direction. The battery storage portion 15 is arranged side by side with the handle portion 20 in a direction (front-to-back direction) orthogonal to the axial direction (up-down direction) of the main body 10. In other words, the first electric blower 14 and the battery storage portion 15 are arranged side by side in a direction orthogonal to the axial direction of the main body 10.

[0076] The handle portion 20 is a portion provided for the user of the electric vacuum cleaner 1 to hold the main body 10. An opening portion 22 for inserting a hand is formed between the handle portion 20 and the main body 10. The opening portion 22 is opened in a manner such that the length in the up-down direction is greater than the length in the front-to-back direction. The electric vacuum cleaner 1 is configured such that the main body 10 can be held by, for example, allowing the user to pass fingers other than the thumb through the opening portion formed by the handle portion 20. The handle portion 20 is provided on the upper side relative to the main body 10. In addition, the handle portion 20 is located on the front side of the main body 10. In addition, the main body 10 has an external exhaust port on one or both sides in the left-right direction for exhausting the exhaust gas of the first electric blower 14 to the outside.

[0077] The first dust collecting section 50 is a part that collects dust sucked by the electric vacuum cleaner 1. The first dust collecting section 50 is connected to the main body 10. Specifically, the first dust collecting section 50 and the first electric blower 14 are arranged side by side in the axial direction (up and down direction) of the main body 10. In addition, the first dust collecting section 50 and the pipe section 38x are arranged side by side in a direction (front and back direction) orthogonal to the axial direction (up and down direction) of the main body 10. In the present embodiment, the first dust collecting section 50 is a cyclone dust collecting container that can centrifugally separate at least a portion of dust from the air sucked in by the action of the electric blower.

[0078] The extension tube 180 is a cylindrical member that detachably connects the main body 10 and the suction piece 190. One end of the extension tube 180 is shaped so as to be inserted into the suction port 38y of the tube 38x provided in the main body 10, and the other end is shaped so as to be connectable to the suction piece 190. By connecting the main body 10 and the suction piece 190 via the extension tube 180, a series of connected paths (air paths) from the suction piece 190 to the main body 10 can be formed.

[0079] The suction tool 190 is directly connected to the suction port 38y of the main body 10, or is indirectly connected via the extension tube 180. The suction tool 190 has a suction port 192 (see Fig.10 ) and a joint portion 194. The suction port 192 opens toward the bottom surface. In addition, the joint portion 194 can be connected to the suction port 38y or the extension tube 180. The characteristic portion of the suction piece 190 will be described in detail later.

[0080] The electric vacuum cleaner 1 is roughly constructed as described above. The configuration of the above-mentioned parts of the electric vacuum cleaner 1 is characteristic. Specifically, in the up-down direction, the upper end of the opening portion 22 of the electric vacuum cleaner 1 is located below the upper end of the battery 15a. In addition, in the up-down direction of the electric vacuum cleaner 1, the upper end of the battery storage portion 15 is located below the upper end of the handle portion 20. The electric vacuum cleaner 1 is bounded by a boundary line H that passes through the center position of the first electric blower 14 and extends in the front-to-back direction, and the battery 15a and the handle portion 20 are arranged on the upper side in the up-down direction. In addition, the electric vacuum cleaner 1 is bounded by a central axis V that passes through the center position of the first electric blower 14 and extends in the up-down direction, and the handle portion 20 and the battery 15a are arranged oppositely. In the up-down direction of the electric vacuum cleaner 1, the tube portion 38x and the handle portion 20 are arranged side by side. The electric vacuum cleaner 1 is configured so that the central axis of the first dust collecting portion 50 is consistent with the central axis V of the first electric blower 14. In addition, the first electric blower 14 may be arranged so that the central axis V is located at a position offset to the front side with respect to the rotation axis of the first dust collecting part 50 .

[0081] Second Implementation Method

[0082] Next, an electric vacuum cleaner 1 according to a second embodiment of the present invention and an electric vacuum cleaner system S including the electric vacuum cleaner 1 will be described. In this embodiment, components common to the above-described electric vacuum cleaner 1 are denoted by the same reference numerals, and detailed descriptions thereof will be omitted.

[0083] 《About the overall structure of electric vacuum cleaner system S》

[0084] like Fig. 9 As shown, the electric vacuum cleaner system S includes an electric vacuum cleaner 1 and a dust collecting device 100. The electric vacuum cleaner system S includes a bracket 200 in addition to the dust collecting device 100, but the bracket 200 may be included as a part of the dust collecting device 100. The electric vacuum cleaner system S can collect dust collected in the electric vacuum cleaner 1 to the dust collecting device 100 when the electric vacuum cleaner 1 is placed on the bracket 200. The electric vacuum cleaner system S has characteristics in the structure of the first dust collecting part 50 of the electric vacuum cleaner 1, the structure of the dust collecting device 100, the structure of the bracket 200, etc. The characteristic structures of the electric vacuum cleaner system S and the electric vacuum cleaner 1 of the second embodiment are described in further detail below.

[0085] <About the Structure of the First Dust Collecting Section 50>

[0086] Below, reference Figures 3 to 9The first dust collecting section 50 is described in detail. The first dust collecting section 50 is detachably provided on the main body 10. The first dust collecting section 50 is a so-called cyclone dust collecting device. That is, the first dust collecting section 50 can introduce the air sucked by operating the first electric blower 14 into the first dust collecting container 52, and after forming a swirling airflow in the first dust collecting container 52, collect dust contained in the air during the process of exhausting the air. In addition, the first dust collecting section 50 can adopt a so-called single-stage or multi-stage separation method, but a single-stage separation method is adopted in this embodiment.

[0087] The first dust collecting section 50 is arranged on one side (lower side) in the up-down direction (the length direction of the electric vacuum cleaner 1) relative to the main body 10. The first dust collecting section 50 has a first dust collecting container 52 (outer cylinder) and a structure 54, and a dust collecting space 56 is formed between them. The first dust collecting section 50 can use the air introduced into the dust collecting space 56 to form a swirling airflow that swirls between the structure 54 and the first dust collecting container 52. The first dust collecting section 50 is detachably arranged at a position below the first electric blower 14 in the main body 10. For example, the first dust collecting section 50 can be a structure in which the bottom side is fixed to the tube 38x and the upper side is provided with a locking button for locking or unlocking with the main body shell 12, or a structure in which the bottom side is provided with a locking button for locking or unlocking with the tube 38x and the upper side is fixed with the main body shell 12.

[0088] Figures 3 to 6 The first dust collecting container 52 shown in the figure is a container for accumulating dust inside. The first dust collecting container 52 is formed as a hollow cylinder. Thus, the first dust collecting unit 50 includes a first dust collecting chamber 52a forming a dust collecting space 56 inside the first dust collecting container 52. The first dust collecting container 52 is opened on the other side (upper side) of the axial direction. In addition, the first dust collecting container 52 has a waste port 52b and an opening and closing portion 52c at the lower end side of the first dust collecting chamber 52a.

[0089] The first dust collecting container 52 has a discarding port 52b (opening) on ​​one side (lower side) in the up-down direction. The discarding port 52b is an opening for discarding dust from the first dust collecting chamber 52a. The discarding port 52b opens at the lower end of the first dust collecting chamber 52a. In addition, when the first dust collecting unit 50 is mounted on the main body 10, the opening and closing portion 52c can close the discarding port 52b at the bottom of the first dust collecting chamber 52a. Therefore, if the opening and closing portion 52c is opened, the dust accumulated in the first dust collecting chamber 52a can be discarded through the discarding port 52b. As an example of the opening and closing portion 52c, a cover or a valve can be considered, but in the present embodiment, the opening and closing portion 52c adopts a cover that can close the discarding port 52b. The opening and closing portion 52c is connected to the first dust collecting chamber 52a (the outer cylinder constituting the first dust collecting container 52) in a manner that can rotate around the rotating shaft 52e. The opening and closing portion 52c has a contacted portion 52f in a region on one side relative to the rotation shaft 52e, and has a closing portion 52g in a region on the other side.

[0090] The abutted portion 52f can abut against the second abutting portion 152 provided in the receiving portion 130 of the dust recovery device 100 which will be described in detail later. In addition, the closing portion 52g is a portion that closes the waste port 52b. The opening and closing portion 52c can apply force to the abutted portion 52f by causing the second abutting portion 152 to abut against the abutted portion 52f, thereby rotating the closing portion 52g in a manner that the closing portion 52g is separated from the waste port 52b. In this way, the waste port 52b can be opened. In addition, it is preferred that a force is applied to the opening and closing portion 52c by a force applying member 52h (a torsion spring in this embodiment) at a portion that is closer to the abutted portion 52f than the rotating shaft 52e. In this way, the closing portion 52g is forced in a direction to close the waste port 52b. The opening and closing portion 52c can apply force to the abutted portion 52f by making the second abutting portion 152 abut against the abutted portion 52f, etc., so as to overcome the force of the force-applying member 52h and apply force to the abutted portion 52f, so as to rotate the closing portion 52g in a manner that the closing portion 52g is separated from the waste port 52b, thereby opening the waste port 52b. In addition, the waste port 52b is formed as an opening surface perpendicular to the axial direction of the first dust collecting container 52, but can also be an opening surface inclined relative to the axial direction of the first dust collecting container 52. For example, the opening surface of the waste port 52b can be inclined toward one side or the other side of the axial direction of the first dust collecting container 52 as it moves away from the rotating shaft 52e. As a result, the dust in the first dust collecting chamber 52a is easy to agglomerate, so it is easy to use the dust recovery device 100 for suction.

[0091] In addition, the first dust collecting unit 50 is configured such that: a first dust collecting unit 50 is provided on either the opening and closing unit 52c (sealing unit 52g) or the first dust collecting container 52. Fig.13The locking portion 55 schematically shown in (a) of FIG. The locking portion 55 can lock the operation of the opening and closing portion 52c when the waste port 52b of the first dust collecting container 52 is closed (closed state) by the opening and closing portion 52c (sealing portion 52g). The locking portion 55 includes an abutted portion 57 and a rotating shaft 58. The abutted portion 57 is rotatably supported by the rotating shaft 58. The abutted portion 57 has a snap-fit ​​portion 57a ​​on one side and an abutted area 57b on the other side across the rotating shaft 58.

[0092] The engaging portion 57a ​​can engage with or disengage the engaged portion 52k provided on the bottom surface of the opening and closing portion 52c. The locking portion 55 can engage the engaging portion 57a ​​with the engaged portion 52k when the waste port 52b of the first dust collecting container 52 is closed by the opening and closing portion 52c, thereby forming a locked state in which the opening and closing portion 52c is fixed to a state in which it cannot be opened or closed (cannot be rotated around the rotating shaft 52e). In addition, a spring can also be used to apply force to the engaging portion 57a ​​so that it rotates in the engaging direction. On the contrary, the locking portion 55 can rotate the abutted portion 57 by applying a pressing force from the bottom to the top to the abutted area 57b located on the opposite side of the engaging portion 57a ​​across the rotating shaft 58 in the abutted portion 57, thereby disengaging the engaging portion 57a ​​from the engaged portion 52k. Thus, the lock portion 55 can be placed in an unlocked state in which the opening and closing portion 52c is freely rotatable (rotatable about the rotation shaft 52e).

[0093] The first dust collecting unit 50 is formed by providing a first dust collecting container 52 with Fig.13 The locking portion 55A is a structure shown in (b). The locking portion 55A can lock the operation of the opening and closing portion 52c when the waste port 52b of the first dust collecting container 52 is closed (closed state) by the opening and closing portion 52c (sealing portion 52g). The locking portion 55A includes an abutted portion 57 and a rotating shaft 58. The abutted portion 57 is rotatably supported by the rotating shaft 58. The abutted portion 57 has a locking portion 57a1 on one side and an abutted area 57b on the other side across the rotating shaft 58.

[0094] The locking portion 57a1 can be engaged with or disengaged from the locked portion 52k1 provided on the opening and closing portion 52c. The locking portion 55A can lock the locking portion 57a1 to the locked portion 52k1 when the waste port 52b of the first dust collecting container 52 is closed by the opening and closing portion 52c, thereby forming a locked state in which the opening and closing portion 52c is fixed to a state in which it cannot be opened or closed (cannot be rotated around the rotating shaft 52e). In addition, the locking portion 57a1 can also be forced by an elastic member 59a (such as a spring or rubber) to rotate it in the locked direction. On the contrary, the locking portion 55A can rotate the abutted portion 57 by applying a pressing force from the bottom to the top to the abutted area 57b located on the opposite side of the locking portion 57a1 across the rotating shaft 58 in the abutted portion 57, thereby disengaging the locking portion 57a1 from the locked portion 52k1. Thus, the lock portion 55A can be placed in an unlocked state in which the opening and closing portion 52c is freely rotatable (rotatable about the rotation shaft 52e).

[0095] In addition, the locking portion 55A is preferably located closer to the tube portion 38x than the rotation shaft 52e to prevent the user from accidentally touching the locking portion 55A. In addition, the locking portion 55A preferably has a housing 59b ( 59b ) that accommodates the abutment portion 57, the rotation shaft 58, and the elastic member 59a. Fig.13 (b) is shown with a two-dot chain line.) In addition, it is preferred that the locked portion 52k1 protrudes further in the radial direction than the first dust collecting container 52.

[0096] like Figure 5 , Figure 6 As shown in the figure, the first dust collecting container 52 has a dust collecting portion inlet 52x (inlet) at the periphery. The dust collecting portion inlet 52x is a portion that becomes an inlet for allowing the air sucked from the suction port 38y to flow into the air path formed inside the tube 38x into the first dust collecting container 52. The dust collecting portion inlet 52x is arranged at a position equivalent to the opening arranged at the end of the tube 38x, for example, in the middle of the up-down direction (axial direction) of the first dust collecting container 52. Therefore, by installing the first dust collecting portion 50 on the main body 10, the dust collecting portion inlet 52x can be connected to the air path formed inside the tube 38x. In addition, the dust collecting portion inlet 52x can introduce the air discharged from the air path formed inside the tube 38x into the interior of the dust collecting space 56 in the tangential direction of the inner peripheral surface of the first dust collecting container 52. Therefore, the air introduced from the dust collecting portion inlet 52x into the inside of the dust collecting space 56 forms a swirling flow that flows along the inner peripheral surface of the first dust collecting container 52.

[0097] like Figure 4 , Figure 6As shown, the structure 54 is a component disposed inside the first dust collecting container 52. The structure 54 is a component that forms a dust collecting space 56 for air to flow into between the structure 54 and the first dust collecting container 52. The structure 54 is configured in a manner that the axial position is substantially consistent with the axial position of the first dust collecting container 52. The structure 54 has a portion (a tapered portion 70 described later) that is formed to become smaller in shape as it moves from one side (the upper side in the figure) toward the other side (the lower side in the figure) in the axial direction. The structure 54 has a first inner cylinder 60 (inner cylinder) and a side cylinder 64, and also has a connector 62 that is not necessarily constituted. The first inner cylinder 60 is connected to the side cylinder 64, but in the case where the connector 62 is provided, the first inner cylinder 60 is connected to at least one of the side cylinder 64 and the connector 62.

[0098] like Figure 4 , Figure 7 As shown in FIG. 1 , the first inner tube 60 includes a tapered portion 70 and an extended portion 72 . In addition, the first inner tube 60 includes a first guide portion 74 and a second guide portion 76 on the outer circumference of the tapered portion 70 .

[0099] The tapered portion 70 is a portion formed so that the outer shape becomes smaller as it moves from one side of the axial direction (the upper side in the figure) toward the other side (the lower side in the figure). The tapered portion 70 is formed in a truncated cone shape, and is formed so that the outer peripheral surface is linearly inclined toward the axis side as it moves from one side of the axial direction toward the other side. The tapered portion 70 is open toward one side of the axial direction (the upper side), and has a closed portion 70a on the other side of the axial direction (the lower side).

[0100] like Figure 4 As shown, the tapered portion 70 is formed such that the outer diameter of the large diameter portion 70b on one side of the axial direction is substantially consistent with the inner diameter of the first dust collecting container 52. In addition, a circumferential groove 70c extending in the circumferential direction is provided on the outer peripheral surface of the large diameter portion 70b. The tapered portion 70 can form a first sealing portion 73 using an airtight component (first airtight component 70d) composed of an O-ring or the like installed on the circumferential groove 70c, and the first sealing portion 73 seals the gap formed between the tapered portion 70 and the inner peripheral surface of the first dust collecting container 52. That is, by placing the tapered portion 70 on the inner side of the first dust collecting container 52 with the closure portion 70a facing the bottom side of the first dust collecting container 52, the first airtight component 70d installed on the circumferential groove 70c is in close contact with the inner peripheral surface of the first dust collecting container 52 to form the first sealing portion 73. In addition, a dust collecting space 56 is formed between the tapered portion 70 (first inner cylinder 60) and the first dust collecting container 52 at a position closer to the other side in the axial direction (the bottom side of the first dust collecting container 52) than the first sealing portion 73. In addition, the first sealing portion 73 is formed at a position closer to the upper side than the dust collecting portion inlet 52x connected to the dust collecting space 56.

[0101] In addition to the function of forming the dust collecting space 56 as described above, the tapered portion 70 also has the function of serving as a dust collecting space exhaust portion 80 for exhausting the dust collecting space 56. Specifically, a plurality of vents 70e formed to communicate the inside and the outside are provided in the circumferential direction on the tapered portion 70. The tapered portion 70 may be formed by resin molding or by a mesh component 82. The mesh component 82 is a mesh component made of a resin material, a metal material, or a combination thereof. Therefore, the mesh component 82 may be used to capture dust contained in the air passing through the vents 70e constituting the dust collecting space exhaust portion 80. Compared with the mesh component 82, the surface of the tapered portion 70 formed by resin molding is smooth, so that dust can be less likely to get stuck.

[0102] The extension portion 72 is a cylindrical portion formed to extend from the tapered portion 70 further to the other side (opening and closing portion 52c side) in the up-down direction. In the present embodiment, the extension portion 72 extends toward the other side in the axial direction with the end (lower end in the example in the figure) on the other side of the axial direction of the tapered portion 70 as the base end. The extension portion 72 is formed to separate from the bottom of the first dust collecting container 52 to one side in the axial direction (upper side in the example in the figure) inside the dust collecting space 56. The extension portion 72 is formed to surround the surrounding of the closed portion 70a. Thus, the extension portion 72 is formed into a cylindrical shape in which the upper end side is closed by the closed portion 70a and the lower end side is open. By setting the extension portion 72 in a manner that surrounds the surrounding of the closed portion 70a, the airflow and dust flying up from the bottom of the first dust collecting container 52 at the axial side position of the dust collecting space 56 collide with the closed portion 70a, and it is difficult to diffuse in a direction intersecting with the axial direction. As a result, in the electric vacuum cleaner 1, dust such as hair and dust contained in the airflow is difficult to be entangled in the tapered portion 70. The extension portion 72 is in a cylindrical shape. Preferably, the extension portion 72 is a cylindrical shape having the same outer dimensions from the upper end to the lower end, or a tapered cylindrical shape whose outer dimensions decrease from the upper end to the lower end. Thus, the airflow and dust smoothly guided toward the other side of the axial direction (the bottom side of the first dust collecting container 52) under the guidance of the first guide portion 74 can be prevented from being entangled in the extension portion 72. In addition, the extension portion 72 is not limited to a cylindrical shape, and can also be a structure in which a plurality of extension components extending in the axial direction are arranged at intervals from each other.

[0103] In addition, the closed portion 70a may also be convex in shape with the center side relative to the outside toward the bottom of the first dust collecting container 52, and more preferably curved. Thus, at the axial side position of the dust collecting space 56, the airflow and dust flying up from the bottom of the first dust collecting container 52 are easily moved toward the extension portion 72 at the closed portion 70a.

[0104] In addition, on the opening and closing portion 52c provided as the bottom of the first dust collecting container 52, a plurality of ribs 52i (protrusions) for limiting the swirling airflow to move the dust are provided. The ribs 52i are provided to extend toward the structure 54. The first dust collecting portion 50 can be formed as a portion without ribs 52i, a portion with only one rib 52i, etc., but in this embodiment, a plurality of ribs 52i are provided at intervals in the circumferential direction. In addition, on the opening and closing portion 52c, a protrusion extending toward the structure 54 (enclosed portion 70a) can also be provided instead of the ribs 52i, or on the basis of the ribs 52i. In the case where the protrusion is provided together with the ribs 52i, the ribs 52i are arranged around the protrusion at intervals along the direction intersecting the axis (radial direction in this embodiment). In addition, the protrusion is columnar, for example, it can be cylindrical, prism-shaped, a columnar with a cross section, or a cylindrical, prism-shaped, or a columnar with a cross section formed into a cone shape toward the structure 54 side. This can prevent the airflow from moving dust collected below the sealing portion 70a. When the bottom of the first dust collecting container 52 is formed into a lid shape that can be opened and closed by rotation, even if dust is entangled in the protrusions and ribs 52i, it is easy to discard the dust.

[0105] like Figure 7 As shown, the first guide portion 74 is a rib-shaped portion provided on the outer peripheral side of the tapered portion 70, and abuts against the inner peripheral surface of the first dust collecting container 52. The first guide portion 74 is arranged between the first dust collecting container 52 and the first inner cylinder 60 when the structure 54 is inserted into the first dust collecting container 52 with the tapered portion 70 and the extension portion 72 facing the bottom side of the first dust collecting container 52. The first guide portion 74 functions as a guide component for guiding the airflow flowing from the dust collecting portion inlet 52x into the dust collecting space 56 and swirling in the direction along the inner periphery of the first dust collecting container 52 to the other side of the axial direction (the bottom side of the first dust collecting container 52). The first guide portion 74 extends in a manner that approaches the dust collecting portion inlet 52x as it moves from one side of the axial direction toward the other side (from the upper side toward the lower side in the example shown in the figure). The end of the first guide portion 74 may also reach the dust collecting portion inlet 52x. In other words, the first guide portion 74 extends in a manner that approaches the dust collecting portion inlet 52x from a position on the upstream side of the swirling direction of the airflow relative to the dust collecting portion inlet 52x as it moves from one side of the axial direction toward the other side (from the upper side toward the lower side in the example shown). In addition, the configuration in which the first guide portion 74 is disposed on the structural body 54 is described as an example, but the configuration in which the first guide portion 74 is disposed on the inner peripheral surface of the first dust collecting container 52 may also be used. In this case, it is preferred that the first guide portion 74 abuts against the outer peripheral surface of the tapered portion 70 (structural body 54).

[0106] The second guide portion 76 is a rib-shaped portion provided on the outer peripheral side of the tapered portion 70, similarly to the first guide portion 74. The second guide portion 76 is a rib that functions as a guide member for guiding the airflow flowing from the dust collecting portion inlet 52x into the dust collecting space 56. The second guide portion 76 is formed to intersect the axial direction between the first dust collecting container 52 and the first inner cylinder 60 and extend along the swirling direction. The second guide portion 76 is connected to the terminal end of the first guide portion 74.

[0107] The connecting body 62 functions as an airflow outflow portion 67 for allowing the air flowing into the dust collecting space 56 to flow out to the outside of the first dust collecting portion 50. Although it is not a necessary structure, the airflow outflow portion 67 may have a filter. In addition, the connecting body 62 may be detachably connected to the first inner cylinder 60. When the connecting body 62 is detachable relative to the first inner cylinder 60, the end of the connecting body 62 on the other side of the axial direction may be connected to the inside of the first inner cylinder 60. Figure 4 As shown in the figure, the connecting body 62 can be composed of a cylindrical frame, for example. The connecting body 62 is arranged on the inner side (the axial side of the first dust collecting part 50) relative to the first inner cylinder 60. The connecting body 62 is connected to both or one side of the first inner cylinder 60 and the one side cylinder 64. In the present embodiment, the connecting body 62 is connected to the first inner cylinder 60. Thus, an internal space 84 is formed between the first inner cylinder 60 and the connecting body 62. The connecting body 62 has a filter 94 for capturing dust contained in the air of the vent 70e flowing into the tapered portion 70. The filter 94 is a mesh filter formed with a plurality of pores. In addition, in the present embodiment, a structure is formed to be configured with a filter 94, but the filter 94 may not be provided.

[0108] like Figure 4 , Figure 6 As shown, the one side cylinder 64 is provided in a direction away from the bottom side of the first dust collecting container 52 (the one side in the axial direction) relative to the above-mentioned connecting body 62. The one side cylinder 64 is provided integrally with the connecting body 62 or is provided detachably, and is provided at a position adjacent to the connecting body 62 on the upper side. Figure 6 As shown, the one side cylinder portion 64 has an enlarged diameter portion 64a, an intermediate portion 64b, and a filter placement portion 64c.

[0109] The enlarged diameter portion 64a is a portion extending from the connector 62 side toward the upper side. The enlarged diameter portion 64a is formed to expand in a conical shape as it moves toward the upper side. In addition, the middle portion 64b is a portion disposed at a position adjacent to the enlarged diameter portion 64a on the upper side in the axial direction. The middle portion 64b is formed to extend along the axial direction of the first dust collecting container 52. A peripheral groove 64d extending in the circumferential direction is provided on the outer peripheral surface of the one side cylinder 64. The one side cylinder 64 can form a second sealing portion 65 using an airtight component (second airtight component 64e) composed of an O-ring or the like installed on the peripheral groove 64d, and the second sealing portion 65 will seal the gap formed between the one side cylinder 64 and the inner peripheral surface of the first dust collecting container 52. The outer diameter of the filter configuration portion 64c is substantially the same as the inner diameter of the first dust collecting container 52. Therefore, there is almost no gap formed between the outer peripheral surface of the filter configuration portion 64c and the inner peripheral surface of the first dust collecting container 52.

[0110] In addition, the filter configuration part 64c is formed with a step portion 64f at the portion constituting the boundary with the middle part 64b in the inner peripheral side. The step portion 64f is provided with an annular groove portion for configuring an airtight component 64j, which is improved by abutting with the lower end of the second filter 64h. The first filter 64g and the second filter 64h are configured on the inner side of the filter configuration part 64c. The first filter 64g is a filter composed of, for example, nonwoven fabrics, sponges, etc. The first filter 64g is configured on the step portion 64f. In addition, the second filter 64h at least has a pleated filter and a frame 64i surrounding the filter. The airtight component 64j abuts with the lower end of the frame 64i. In addition, the pleated filter constituting the second filter 64h is configured on the first filter 64g, and the first filter 64g is located inside the frame 64i in a manner that the frame 64i surrounds the filter. In addition, the second filter 64h is provided with an airtight component 64k on the upper surface of the frame 64i, and the airtightness is improved by the airtight component 64k abutting against the air intake side component 42a. In addition, since the pleated filter of the second filter 64h is separated from the first filter 64g, the air is dispersed in the space, so the surface of the pleated filter can be effectively and flexibly utilized. Thus, the problem of the filter being clogged earlier and the attraction force being reduced can be solved.

[0111] 《About Dust Recovery Device 100》

[0112] like Figure 8 , Fig. 9 , Fig.10As shown in the figure, the dust recovery device 100 is arranged on the back side of the pillar 202 constituting the bracket 200. The dust recovery device 100 is connected to the first dust collecting part 50 of the electric vacuum cleaner 1, thereby recovering dust from the electric vacuum cleaner 1. The dust recovery device 100 has a device body and a receiving part 130, and the device body includes a second dust collecting part 110 and a second electric blower 120. Preferably, when the electric vacuum cleaner 1 is connected to the dust recovery device 100, the device body of the dust recovery device 100 is located directly below at least one of the first electric blower 14 and the battery 15a. Thus, the back side of the pillar 202 and the space below the electric vacuum cleaner 1 can be flexibly utilized. In addition, the dust recovery device 100 is configured as follows: a space part 132 and a support part 134 are provided in the receiving part 130, and the receiving part 130 is connected to the second dust collecting part 110 in a manner of being connected via a connecting part 136. Furthermore, the dust collecting device 100 includes an opening unit 150, which is used to open the first dust collecting unit 50 of the electric vacuum cleaner 1 by arranging the first dust collecting unit 50 on the receiving portion 130. Thus, the dust collecting device 100 can open the first dust collecting unit 50 and make the suction force generated by the operation of the second electric blower 120 work, so as to collect dust from the first dust collecting unit 50 to the second dust collecting unit 110 via the connecting portion 136. The configuration of each unit will be described in further detail below.

[0113] The second dust collecting part 110 is a part that collects dust sucked from the first dust collecting part 50 of the electric vacuum cleaner 1. The second dust collecting part 110 may be a dust collecting part that directly collects dust inside, a cyclone-type dust collecting part like the first dust collecting part 50, or a paper bag-type dust collecting part that can collect dust inside a paper bag by installing a paper bag. Fig.10 As shown, the second dust collecting part 110 includes a second dust collecting container 112 and a connecting part 114. The second dust collecting container 112 includes a cover that can open and close the container body, and the cover is locked to the container body by a locking part 110a.

[0114] The second dust collecting container 112 is a hollow container having a second dust collecting chamber 112a therein. An exhaust hole for discharging the exhaust gas of the second electric blower 120 to the outside is provided in the second motor storage chamber 122 (blower configuration space) storing the second electric blower 120.

[0115] The connecting portion 114 includes a socket 114a and a connecting passage 114b. The socket 114a is a portion connected to a connecting pipe 136b, and the connecting pipe 136b constitutes a connecting portion 136 connecting the receiving portion 130 and the second dust collecting portion 110. The connecting passage 114b is a passage connecting the socket 114a and a connecting hole 112c provided in the second dust collecting container 112 in a manner that air and dust can pass through.

[0116] The second electric blower 120 can generate attraction as it moves. The second electric blower 120 is arranged in the second motor storage chamber 122, and the second motor storage chamber 122 is connected to the second dust collection container 112 of the second dust collection unit 110 via the exhaust hole 112e. As long as the second electric blower 120 can generate attraction relative to the second dust collection container 112, its configuration, setting posture, etc. can be appropriately set. In this embodiment, considering the tendency to easily generate vibration in the radial direction of the motor provided by the second electric blower 120 as the second electric blower 120 moves, and the second motor storage chamber 122 is arranged at the bottom side of the dust recovery device 100, etc., the second electric blower 120 is arranged in a manner such that the rotating shaft of the motor provided by the second electric blower 120 faces the up and down direction, so as to suppress the generation of vibration sound in the contact part with the ground of the device body of the dust recovery device 100.

[0117] like Fig. 9 As shown in FIG. 1 and FIG. 2 , the receiving portion 130 accommodates the first dust collecting portion 50 of the electric vacuum cleaner 1. Specifically, the receiving portion 130 has a first dust collecting portion recess 130a, which is formed to be fitted with a portion of the lower end side of the first dust collecting portion 50. Fig.11 As shown, the receiving portion 130 has a pipe recess 130b, which is formed to be engaged or abutted with the pipe portion 38x of the main body 10. The pipe recess 130b can also be composed of a cover that can move in the up and down directions. Specifically, the cover constituting the pipe recess 130b can also be supported from below by a spring, and when the pipe portion 38x is engaged or abutted, the cover moves downward, and when the engagement or abutment of the pipe portion 38x is released, the cover moves upward by the action of the spring. In addition, the pipe recess 130b can also be engaged or abutted with a part of the extension pipe 180 at the periphery. Furthermore, the receiving portion 130 is provided with a release unit 140 (release operation unit) and an opening unit 150.

[0118] The release unit 140 releases the lock of the locking portion 55, 55A. The release unit 140 can be provided in the first dust collecting portion 50 or the dust collecting device 100, but in the present embodiment, it is provided in the dust collecting device 100. In the present embodiment, the receiving portion 130 is provided with a first abutting portion 142 which functions as the release unit 140. The first abutting portion 142 protrudes in a protruding shape so that when the first dust collecting portion 50 is fitted into the first dust collecting portion recess 130a, as shown in FIG. Fig.11As shown, the first dust collecting part 50 abuts against the abutted area 57b of the abutted part 57 constituting the locking part 55, 55A. Therefore, by inserting the first dust collecting part 50 into the first dust collecting part recess 130a, a pressing force is applied from the first abutting part 142 to the abutted area 57b, so that the abutted part 57 rotates around the rotation axis 58. Along with this, the engaging part 57a and the locking part 57a1 of the abutted part 57 are disengaged from the engaged part 52k and the locked part 52k1 provided on the bottom surface of the opening and closing part 52c, and the locking part 55, 55A becomes unlocked.

[0119] The opening unit 150 is used to open the first dust collecting chamber 52a of the first dust collecting section 50. The opening unit 150 can be opened in structure (mechanism) by rotating the opening and closing section 52c provided in the first dust collecting section 50. Specifically, Fig.11 , Fig.15 As shown, when the first dust collecting part 50 is fitted into the first dust collecting part recess 130a, the second contact part 152 protruding in a protruding shape is provided at the position where the contacted part 52f of the opening and closing part 52c reaches, and acts as the opening unit 150. When the first dust collecting part 50 is fitted into the first dust collecting part recess 130a, the second contact part 152 contacts the contacted part 52f on the side of the first dust collecting part 50. When the second contact part 152 contacts the contacted part 52f, the opening and closing part 52c rotates around the rotation axis 52e and becomes an open state. In the case of having a force applying member 52h, a pressing force is applied in a direction opposite to the force of the force applying member 52h, so that the opening and closing part 52c rotates around the rotation axis 52e and becomes an open state. On the other hand, in the case of having a force-applying member 52h, when the first dust collecting unit 50 is removed from the first dust collecting unit recess 130a to release the engagement between the two, the pressing force applied from the second abutting portion 152 to the abutted portion 52f is released. Along with this, the opening and closing portion 52c is restored to a closed state by the force of the force-applying member 52h. In addition, it can also be configured so that when the opening and closing portion 52c is restored to a closed state, the opening and closing portion 52c is engaged (locked) with the first dust collecting container 52.

[0120] The amount of the first abutment portion 142 constituting the above-mentioned release unit 140 protruding upward (on the connection side with the first dust collecting portion 50) is greater than that of the second abutment portion 152 constituting the opening unit 150. Therefore, when the first dust collecting portion 50 is embedded in the first dust collecting portion recess 130a of the receiving portion 130 in order to install the electric vacuum cleaner 1 on the dust recovery device 100, the first abutment portion 142 abuts against the abutted area 57b to release the engagement (engagement) between the engaging portion 57a, the locking portion 57a1 and the engaged portion 52k, the locked portion 52k1, thereby achieving a locked released state (unlocked state). Then, the second abutment portion 152 abuts against the abutted portion 52f. As a result, as Fig.12In addition, preferably, when the first dust collecting part 50 is removed from the first dust collecting part recess 130a, the second contact part 152 is separated from the contacted part 52f, so that the opening and closing part 53c is rotated toward the closing direction by the force of the force applying member 52h, and then, the first contact part 142 is separated from the contacted area 57b, so that the engaging part 57a, the locking part 57a1 and the engaged part 52k, the locked part 52k1 are engaged (locked) in a state (locked state).

[0121] In addition, the space portion 132 provided in the receiving portion 130 is a space capable of accommodating the opening and closing portion 52c which is in an open state by fitting the first dust collecting portion 50 into the first dust collecting portion recess 130a, and is formed at a position in the opening direction (the lower side in this embodiment) of the opening and closing portion 52c relative to the first dust collecting portion recess 130a. Therefore, the opening and closing portion 52c does not interfere with the receiving portion 130, and the opening and closing action can be smoothly performed.

[0122] Furthermore, the receiving portion 130 is provided with a support portion 134, and the opening and closing portion 52c which is in an open state by fitting the first dust collecting portion 50 into the first dust collecting portion recess 130a can be supported by the support portion 134. In the present embodiment, when the opening and closing portion 52c is in an open state, the opening and closing portion 52c is in an inclined state. Therefore, the support portion 134 is formed in a state inclined along the opening and closing portion 52c in an open state.

[0123] The receiving portion 130 is connected to the second dust collecting portion 110 via the connecting portion 136 so as to be able to attract dust from the first dust collecting portion 50 toward the second dust collecting portion 110. The connecting portion 136 has a connecting port 136a connected to the first dust collecting portion recess 130a and a connecting pipe 136b connected to the connecting port 136a. The connecting pipe 136b is composed of a hose, a pipe, etc. (a pipe in this embodiment). The connecting portion 136 is connected to the first dust collecting portion 50 that is in an open state by embedding the first dust collecting portion recess 130a of the receiving portion 130. The connecting portion 136 is formed such that the interval between the opening and closing portion 52c in the open state and the inner wall of the connecting portion 136 becomes narrower as the dust is attracted downstream from the first dust collecting portion 50 toward the second dust collecting portion 110. In addition, the part of the connecting pipe 136b on the opposite side of the connecting port 136a is connected to the socket 114a of the connecting portion 114 provided on the second dust collecting portion 110. Thus, the receiving portion 130 is in a state of being supported by the connecting pipe 136b on the upper side relative to the second dust collecting portion 110. Therefore, by embedding the first dust collecting portion 50 into the first dust collecting portion recess 130a of the receiving portion 130, the electric vacuum cleaner 1 is supported by the connecting pipe 136b via the receiving portion 130. In addition, the connecting pipe 136b is in a state of being parallel to the extension pipe 180 embedded in the pipe recess 130b of the receiving portion 130. Therefore, when the suction piece 190 connected to the front end side of the extension pipe 180 is arranged on the bracket 200 and the first dust collecting portion 50 is embedded in the receiving portion 130, the electric vacuum cleaner 1 is in a state of being stably supported by the extension pipe 180 and the connecting pipe 136b arranged in parallel.

[0124] 《Regarding the control of electric vacuum cleaner system S》

[0125] The electric vacuum cleaner system S may be configured such that when the electric vacuum cleaner 1 is connected to the dust collecting device 100, the dust collecting device 100 starts to operate. It may also be configured such that by connecting the electric vacuum cleaner 1 to the dust collecting device 100, the electric vacuum cleaner 1 is brought into contact with a switch provided on the bracket 200 and turned on, so that the dust collecting device 100 starts to perform a suction operation. As another embodiment, it may also be configured such that the bracket 200 is configured to have a charging mechanism, and when it is detected that the bracket 200 and the electric vacuum cleaner 1 are powered on, the dust collecting device 100 starts to perform a suction operation. In this case, it is sufficient to configure such that wiring is performed between the power-on terminal of the bracket 200 and the control unit separately from the wiring for charging so as to detect power-on.

[0126] 《Variation Example》

[0127] The electric vacuum cleaner system S of this embodiment adopts the above-mentioned structure, but it can be different from the above-mentioned structure within the scope of the main purpose of the present invention. For example, in this embodiment, by embedding the first dust collecting part 50 into the receiving part 130, the first contact part 142 naturally contacts the contacted area 57b of the contacted part 57, and the second contact part 152 naturally contacts the contacted part 52f, but the present invention is not limited to this.

[0128] Specifically, the first contacting portion 142 can be configured to be movable by providing a first operating portion for moving the first contacting portion 142, and the first contacting portion 142 can be made to contact the contacted area 57b by operating the first operating portion. Similarly, the second contacting portion 152 can be configured to be movable by providing a second operating portion for moving the second contacting portion 152, and the second contacting portion 152 can be made to contact the contacted portion 52f by operating the second operating portion.

[0129] Here, as a structure in which the first abutting portion 142 and the second abutting portion 152 are formed into a movable type, two methods can be considered. In method 1 in which the first abutting portion 142 is not formed into a movable type but the second abutting portion 152 is formed into a movable type, when the first dust collecting portion 50 is accommodated in the receiving portion 130, the lock of the locking portion 55 is released by the first abutting portion 142, so that the second abutting portion 152 can be abutted against the abutted portion 52f by operating the second operating portion, so that the opening and closing portion 52c is in an open state. Here, the second operating portion operates between a first position in which the second abutting portion 152 abuts against the abutted portion 52f and a second position in which the second abutting portion 152 is separated from the abutted portion 52f, but in the case of having a force-applying member 52h, it is preferred to have a fixing mechanism that fixes the second operating portion in the first position so that the user does not need to continue to operate the second operating portion.

[0130] Next, in method 2 in which both the first abutting portion 142 and the second abutting portion 152 are formed to be movable, the first abutting portion 142 can be used to unlock the locking portion 55 by the first operating portion while the first dust collecting portion 50 is accommodated in the receiving portion 130, and the second operating portion can be operated to cause the second abutting portion 152 to abut against the abutted portion 52f, thereby placing the opening and closing portion 52c in an open state.

[0131] Here, in method 2, the second operating part moves between a first position where the second abutting part 152 abuts against the abutted part 52f and a second position where the second abutting part 152 and the abutted part 52f are separated, but in the case of having a force-applying component 52h, it is preferred to have a fixing mechanism that fixes the second operating part at the first position so that the user does not need to continue to operate the second operating part.

[0132] In addition, in method 2, the first operating part moves between a first position in which the first abutting part 142 abuts against the abutted part 57 and a second position in which the first abutting part 142 and the abutted part 57 are separated. However, when the locking part 55 is urged in a locking direction by a spring, it is preferred to have a fixing mechanism that fixes the first operating part in the first position so that the user does not need to continue to operate the first operating part.

[0133] In addition, in methods 1 and 2, the fixing mechanism may be, for example, a mechanism in which the first and second operating parts are embedded in a small groove (first position) from a relatively large groove (second position), or an L-shaped groove having a horizontal groove (first position) and a vertical groove extending downward (the lower end of the vertical groove is the second position), or a structure having other movable parts that support the first and second operating parts at the first position or release the support at the first position. Thus, the user of the electric vacuum cleaner system S releases the lock of the locking part 55, 55A or opens the closing part 52g at a desired time, thereby transferring dust from the first dust collecting part 50 to the second dust collecting part 110.

[0134] In addition, the dust collecting device 100 is formed to connect the device body and the receiving portion 130 through the connecting pipe 136b, but is not limited to this. It can also be formed to have a structure in which the device body has the receiving portion 130, and the device body and the connecting path 114b extend together to the height of the first dust collecting part 50 embedded in the receiving portion 130 connected to the connecting path 114b. In this case, there is no need to provide a connecting pipe 136b separately.

[0135] In addition, the first dust collecting part 50 is a structure that can open and close the bottom of the first dust collecting container 52 by opening and closing the opening and closing part 52c, but an opening that can be opened and closed can also be provided on the side, and the opening is used as a waste port. Even in this case, as long as the receiving part 130 receives the waste port side of the side of the first dust collecting container 52, the opening and closing part 52c can be opened in an inclined direction or a horizontal direction by rotating.

[0136] In addition, the electric vacuum cleaner 1 of this embodiment is described as an example in which the main body 10 is connected to the suction piece 190 by the extension pipe 180 and the dust collection device 100 is connected, but the invention is not limited thereto. The electric vacuum cleaner 1 can also be connected to the dust collection device 100 in a state in which the suction piece 190 is installed in the suction port 38y of the main body 10.

[0137] The electric vacuum cleaner system S can be constructed as follows: the main body 10 of the electric vacuum cleaner 1 is embedded in the receiving portion 130 of the dust collecting device 100, and the second electric blower 120 is operated with the opening and closing portion 52c opened, so that not only the dust located in the first dust collecting portion 50 can be attracted, but also the dust attached to the first filter 64g and the second filter 64h (a single filter when one of the first filter 64g and the second filter 64h is configured). Specifically, Fig.14 As shown, regarding the structure 54 of the electric vacuum cleaner 1, the extension portion 72 is extended toward the closed portion 52g (opening and closing portion 52c) constituting the bottom of the first dust collecting portion 50. As shown in the example in the figure, the extension portion 72 can reach the opening and closing portion 52c in a closed state and abut against it. Fig.14 In the example shown, by adopting a structure in which the closing portion 70a provided on the extension portion 72 (first inner cylinder 60) illustrated in the above embodiment is not provided, an opening is provided in a portion corresponding to the closing portion 70a. Thus, the first inner cylinder 60 and the extension portion 72 are connected internally. By adopting such a structure, by embedding the main body 10 of the electric vacuum cleaner 1 into the receiving portion 130 of the dust recovery device 100, and operating the second electric blower 120 with the opening and closing portion 52c opened, the suction force of the second electric blower 120 also acts on the first filter 64g and the second filter 64h, and dust attached to the first filter 64g and the second filter 64h can be removed.

[0138] In addition, a configuration may be adopted in which an on-off valve is provided to adjust the air flowing into the dust collecting space 56 from the dust collecting portion inlet 52x by the suction of the second electric blower 120, the on-off valve is closed when removing the dust attached to the first filter 64g and the second filter 64h, and the on-off valve is opened in other cases. When such an on-off valve is provided, by closing the on-off valve, the air easily flows from the external exhaust opening (opening for discharging the exhaust gas of the first electric blower 14 to the outside of the main body 10) of the main body 10 through the first filter 64g and the second filter 64h (a single filter when one of the first filter 64g and the second filter 64h is arranged) and passes through the extension portion 72 to the dust collecting device 100 under the suction of the second electric blower 120, so that the dust attached to the first filter 64g and the second filter 64h (a single filter when one of the first filter 64g and the second filter 64h is arranged) can be more reliably attracted.

[0139] In addition, the above-mentioned on-off valve only needs to be provided at the suction port 192 (refer to Fig.10 ) to any position of the ventilation path from the dust collecting section inlet 52x. Fig.14As shown by the hatched line in the figure, the on-off valve 172 (first on-off valve, second on-off valve) for opening and closing the opening in the tube 38x opposite to the dust collecting section inlet 52x can be used as the above-mentioned on-off valve. The on-off valve 172 can be a structure that is opened and closed electrically, or a structure that is opened and closed by manual operation (for example, a structure of a gate section with a gate mechanism, etc.). In the case where the on-off valve 172 can be opened and closed electrically, it can be configured to provide an operation button for opening and closing on the electric vacuum cleaner 1, or by installing the electric vacuum cleaner 1 on the dust recovery device 100, the electric vacuum cleaner 1 is closed when the above-mentioned power-on is detected between the electric vacuum cleaner 1 and the dust recovery device 100, and is opened if the power-on is not detected.

[0140] In addition, if Fig.14 As shown, an on-off valve 170 (third on-off valve) that can be opened and closed may also be provided inside the extension portion 72 of the structure 54. The on-off valve 170 is rotated downward by the suction of the second electric blower 120 to open, and when the suction of the second electric blower 120 stops, it rotates in a direction to close the flow path inside the extension portion 72. Thus, after the suction of the second electric blower 120 stops, even if there is dust that falls off from the first filter 64g and the second filter 64h, the dust can be received by the on-off valve 170 in the closed state. Thus, after the suction of the second electric blower 120 stops, dust can be suppressed from adhering to the on-off portion 52c in the open state, and thus, when the on-off portion 52c in the open state is closed, dust can be reduced from falling from the on-off portion 52c.

[0141] In addition, the opening and closing valve 172 is described for the purpose of removing not only the dust in the dust collecting space 56 but also the dust attached to the first filter 64g and the second filter 64h (a single filter when one of the first filter 64g and the second filter 64h is configured), but it is not limited to this. The opening and closing valve 172 can be used for the purpose of removing the dust in the dust collecting space 56 alone. In this case, the extension part 72 may reach the opening and closing part 52c or may not reach it, and the closing part 70a may also exist. In addition, a gate for opening and closing the external discharge port of the main body 10 may be provided instead of the opening and closing valve 172 or on the basis of the opening and closing valve 172. In the case where the gate is provided instead of the opening and closing valve 172, when the gate is closed, air flows from the dust collecting part inlet 52x into the dust collecting space 56, and an air flow toward the second dust collecting part 110 can be easily generated, so that the dust in the first dust collecting chamber 52a can be removed. When a gate is provided in addition to the on-off valve 172, it is sufficient to operate to open either one of them.

[0142] In addition, it is preferred that an airtight member 160 such as an O-ring is provided to surround the periphery of the sealing portion 52g when the main body 10 is embedded in the receiving portion 130 of the dust collecting device 100. The airtight member 160 may be provided at either or both of the receiving portion 130 or the bottom of the first dust collecting container 52.

[0143] In addition, if Fig.15 As shown, the first dust collecting part 50 can be configured to position the structure 54 relative to the first dust collecting container 52. Specifically, Fig.15 The illustrated first dust collecting section 50 is configured such that a first convex portion 64x protruding radially outward is provided at a predetermined position in the circumferential direction of a side cylinder portion 64 constituting the structure 54, and a second convex portion 64y protruding radially outward is also provided at a predetermined position in the circumferential direction of a frame 64i for arranging a second filter 64h. Fig.15 The illustrated first dust collecting container 52 has an embedding portion 53 into which the first convex portion 64x and the second convex portion 64y are embedded. Therefore, the first dust collecting portion 50 is formed by embedding the first convex portion 64x and the second convex portion 64y into the embedding portion 53 and installing the structure 54 and the frame 64i into the first dust collecting container 52, thereby Fig.16 As shown, the frame body 64i constituting the upper end portion of the first dust collecting portion 50 can be arranged in a state where it is positioned at a predetermined position in the circumferential direction of the first dust collecting container 52.

[0144] If the frame 64i constituting the upper end of the first dust collecting part 50 can be positioned at a predetermined circumferential position of the first dust collecting container 52 as described above, the first convex portion 64x and the second convex portion 64y protruding from the embedding portion 53 toward the outside of the first dust collecting container 52 can be embedded in the concave portion 10b of the main body 10, so that the first dust collecting part 50 can be installed in a manner that does not deviate in the left-right direction or the circumferential direction. Fig.17 As shown, a configuration is formed to give an inclination to the portion (dust container connection portion 10a) of the main body 10 connected to the first dust collecting portion 50. For example, by forming a configuration to give an inclination to the dust collecting container connection portion 10a in a manner such that the thickness of the seal provided on the dust collecting container connection portion 10a is different depending on the location, when the first dust collecting portion 50 is mounted on the main body 10 by rotating with the engagement position of the tube portion 38x and the first dust collecting portion 50 as a fulcrum, the upper end of the first dust collecting portion 50 can slide smoothly on the lower end of the main body 10.

[0145] In the above-mentioned embodiment or modification, the following structure is illustrated: by forming a structure in which a release unit 140 (first abutment portion 142) and an opening unit 150 (second abutment portion 152) are provided on the receiving portion 130, the locking portion 55, 55A is released by the release unit 140, and the opening and closing portion 52c is rotated by the opening unit 150 to make it open, but the present invention is not limited to this. The electric vacuum cleaner system S may also be configured, for example, as follows: the release unit 140 (first abutment portion 142) is not provided on the receiving portion 130, and the locking portion 55, 55A can be manually operated, or the opening unit 150 (second abutment portion 152) is not provided and the opening and closing portion 52c can be opened. In addition, in the above-mentioned embodiment or modification, the structure in which the second electric blower 120 is provided on the second dust collecting portion 110 is illustrated, but the present invention is not limited to this, and the second electric blower 120 may not be provided. In the case where the second electric blower 120 is not provided, the electric vacuum cleaner system S may also be configured, for example, to open the opening and closing portion 52c of the first dust collecting portion 50 (first dust collecting container 52) of the electric vacuum cleaner 1 provided (installed) on the receiving portion 130 to allow dust to fall into the second dust collecting portion 110, or to apply air flow into the first dust collecting portion 50 by additionally operating the first electric blower 14 on the basis of opening the opening and closing portion 52c of the first dust collecting portion 50 provided on the receiving portion 130, so that dust falls from the first dust collecting portion 50 to the second dust collecting portion 110. These modified examples are described in further detail below.

[0146] [Variation Example of the Configuration in Which the Opening Unit 150 (Second Abutting Portion 152) Is Not Provided in the Receiving Portion 130]

[0147] The following, for example Fig.18 The modified example of the electric vacuum cleaner system S in which the opening unit 150 (the second contact portion 152) is not provided in the receiving portion 130 is described in detail. In addition, in this modified example, the same reference numerals are given to the same structures as those described in the above-mentioned embodiment, and the description of each structure is simplified or omitted.

[0148] like Figure 1 , Figure 2 As shown in FIG. 1 and FIG. 2 , the vacuum cleaner system S according to the present modification includes the vacuum cleaner 1 and the dust collecting device 100 , similarly to the above-described embodiment. The vacuum cleaner 1 includes the main body 10 and the first dust collecting unit 50 .

[0149] The main body 10 has a first electric blower 14 that generates suction. In addition, the first dust collecting unit 50 is used to collect dust, and in addition to the dust collecting container (first dust collecting container 52), as shown in FIG. Fig.13As shown in (b) and the like, it also includes an opening and closing portion 52c, a force applying member 52h and a locking portion 55A. The first dust collecting container 52 is a container for storing dust. The opening and closing portion 52c can open and close the waste port 52b provided at the bottom of the first dust collecting container 52 when the first dust collecting portion 50 is installed on the main body 10. The locking portion 55A is locked in a state where the opening and closing portion 52c is closed (a state where the waste port 52b is closed by the opening and closing portion 52c) so as to suppress the opening and closing portion 52c from becoming an open state. The locking portion 55A is provided on the outside of the first dust collecting container 52. The locking portion 55A includes a locking portion 57a1 that can be engaged with or disengaged from the opening and closing portion 52c. The locking portion 55A is present at a position closer to the suction port 38y of the main body 10 than the rotation axis 52e of the opening and closing portion 52c. In addition, if the dust collecting device 100 is provided with the second electric blower 120, the force applying member 52h may be configured to apply force in the direction of closing the opening and closing portion 52c, and the opening and closing portion 52c may be opened by the suction force from the dust collecting device 100. However, here, the force applying member 52h may be configured to apply force in the direction of opening the opening and closing portion 52c when the locking portion 55A is released, or the force applying member 52h may be configured to be opened by the deadweight of the opening and closing portion 52c without providing the force applying member 52h. The first dust collecting portion 50 has such a configuration, and the locking portion 57a1 is rotatably supported around the rotating shaft 58, and the rotating shaft 58 is along a direction orthogonal to the central axis passing through the waste port 52b.

[0150] The dust collecting device 100 includes a second dust collecting unit 110. The second dust collecting unit 110 collects dust from the electric vacuum cleaner 1 by communicating with the first dust collecting unit 50. Fig.18 As shown, in this modified example, the dust collecting device 100 is configured as follows: a first contact portion 142 is provided in the receiving portion 130 as a release unit 140, thereby enabling the locking portion 55A to be released, and on the other hand, the opening unit 150 provided as the second contact portion 152 in the above embodiment is omitted. Therefore, the dust collecting device 100 can make the first contact portion 142 contact with the locking portion 57a1 by embedding the first dust collecting portion 50 (first dust collecting container 52) in the receiving portion 130, thereby releasing the locking of the locking portion 57a1 with the opening and closing portion 52c, and making the opening and closing portion 52c open.

[0151] Here, as described above, the dust recovery device 100 may not have the second electric blower 120. In this case, a method may be adopted in which a force-applying member 52h is provided to apply force in the direction of opening the opening and closing portion 52c when the locking portion 55A is released, or a method in which the force-applying member 52h is not provided and the opening and closing portion 52c is opened by its own weight. In addition, in the case of a configuration in which the second electric blower 120 is omitted, the electric vacuum cleaner system S may be configured as follows: in the state in which the opening and closing portion 52c is opened, a vibration (air flow) generated by driving the first electric blower 14 is applied to the first dust collecting portion 50 (first dust collecting container 52), and the dust inside the first dust collecting container 52 is promoted to be collected by the second dust collecting portion 110 by the influence of the vibration (air flow).

[0152] In addition, in the above-mentioned embodiment and the illustration of this modification, an example is shown in which the abutted portion 57 is supported to be rotatable in the vertical direction around the rotating shaft 58, but the present invention is not limited thereto, and the abutted portion 57 can also be supported by the rotating shaft 58 in a manner that can be rotatable in the horizontal direction (a direction intersecting the axial direction of the main body 10 in the vertical direction). In addition, in the case where the release unit 140 is provided in the electric vacuum cleaner 1 instead of the dust collection device 100, it is sufficient to provide a switch for pressing the abutted area 57b in the first dust collecting part 50, or to press the switch for pressing the locking portion 57a1 in the direction of separation of the locking portion 57a1 and the opening and closing portion 52c (locked portion 52k1). In addition, when the electric vacuum cleaner 1 is removed from the dust collection device 100, the user can directly release the locking portion 55A. Specifically, the user can press the abutted area 57b, or separate the locking portion 57a1 from the opening and closing portion 52c.

[0153] [Variation Example of the Configuration in Which the Releasing Unit 140 (First Abutting Unit 142) and the Opening Unit 150 (Second Abutting Unit 152) Are Not Provided in the Receiving Unit 130]

[0154] Below, for Fig. 22 The modified example of the electric vacuum cleaner system S in which the release unit 140 (first abutment portion 142) and the opening unit 150 (second abutment portion 152) are not provided in the receiving portion 130 is described in detail. In addition, in this modified example, the same figure marks are marked for the same structures as those described in the above-mentioned embodiment, and the description of each structure is simplified or omitted.

[0155] like Figure 1 , Figure 2 As shown in FIG. 1 and FIG. 2 , the vacuum cleaner system S according to the present modification includes the vacuum cleaner 1 and the dust collecting device 100 , similarly to the above-mentioned embodiment and the modification. The vacuum cleaner 1 includes the main body 10 and the first dust collecting unit 50 .

[0156] The main body 10 includes a first electric blower 14 that generates suction force. In addition, the first dust collecting unit 50 collects dust and includes, in addition to a dust collecting container (first dust collecting container 52), Fig.13 The opening and closing portion 52c, the locking portion 55A and the biasing member 52h shown in (b) are shown.

[0157] In the first dust collecting section 50, the dust collecting container (first dust collecting container 52) is a container having a dust collecting chamber 52a for storing dust. In addition, the opening and closing section 52c can open and close the waste port 52b provided at the bottom of the first dust collecting container 52 when the first dust collecting section 50 is installed on the main body 10. The opening and closing section 52c can be moved in a direction away from the dust collecting chamber 52a by a release operation relative to the locking section 55A, thereby becoming an open state. The locking section 55A includes a locking section 57a1 that can be engaged with or disengaged from the opening and closing section 52c. Preferably, the locking section 57a1 can be engaged with or disengaged from a locked section 52k1 provided on the opening and closing section 52c. If the user presses the abutted area 57b, or separates the locking section 57a1 from the closing section 52c, the locking section 55A is released. Fig. 20 As shown, in this modified example, the locking portion 57a1 is arranged to be exposed from the receiving portion 130 when the first dust collecting portion 50 (first dust collecting container 52) is arranged on the receiving portion 130. That is, as long as it is exposed in a manner that the user can contact it from the outside of the receiving portion 130, the locking portion 57a1 can exist in the receiving portion 130 or outside the receiving portion 130. The locked portion 52k1 is arranged to protrude from the waste port 52b in a direction away from the central axis (the cylindrical axis extending in the up-down direction) of the waste port 52b passing through the first dust collecting container 52 when the opening and closing portion 52c is in the closed state.

[0158] like Fig.13 As shown in (b), the locking portion 55A locks the opening and closing portion 52c in a closed state. The locking portion 55A has a locking portion 57a1. The locking portion 57a1 is supported in the first dust collecting portion 50 so as to be rotatable around a rotating shaft 58, which is along a direction orthogonal to the central axis (cylindrical axis extending in the up-down direction) of the waste port 52b passing through the first dust collecting container 52.

[0159] Here, in this modification, Fig. 20As shown, the locking portion 55A is exposed from the receiving portion 130 when the first dust collecting portion 50 (first dust collecting container 52) is set in the receiving portion 130, and can be engaged with or disengaged from the opening and closing portion 52c. That is, in this modified example, as described in detail later, a notch portion 130x is provided in the receiving portion 130, and the locking portion 55A is exposed in a manner that can be operated from the outside of the receiving portion 130 through the notch portion 130. In other words, as long as the locking portion 55A is exposed in a manner that can be operated from the outside of the receiving portion 130, the locking portion 57a1 can be present in the receiving portion 130, or it can extend from the notch portion 130x to the outside of the receiving portion 130. In addition, the notch portion 130x is provided at a position opposite to the locking portion 55A. The notch portion 130x is in Fig. 20 The upper end of the receiving portion 130 is formed into an open shape in which the upper end of the receiving portion 130 is closed, but it can also be an open shape in which the upper end of the receiving portion 130 is open. In the case of an open shape in which the upper end of the receiving portion 130 is open, it is easy to suppress the receiving portion 130 from interfering with the locking portion 57a1 when the receiving portion 130 receives the first dust collecting portion 50. In addition, the locking portion 55A is arranged along the outer side and side wall (peripheral wall) of the first dust collecting container 52. It is preferably present on the side of the cylindrical side wall (peripheral wall) of the first dust collecting container 52 close to the suction port 38y. In addition, in other words, the locking portion 55A is present at a position closer to the suction port 38y of the main body 10 than the rotating shaft 52e of the opening and closing portion 52c. In addition, the force-applying component 52h applies force in the direction of closing the opening and closing portion 52c, and when the locking portion 55A is released, the opening and closing portion 52c is opened by the attraction of the dust recovery device 100. However, it can also be constructed as a force-applying component 52h that applies force in the direction of opening the opening and closing portion 52c, and it can also be constructed so that the force-applying component 52h is not provided and the opening and closing portion 52c is opened by its own weight.

[0160] The dust collecting device 100 includes a second dust collecting part 110 for collecting dust. The second dust collecting part 110 communicates with the first dust collecting part 50 to collect dust from the electric vacuum cleaner 1. The dust collecting device 100 includes a receiving part 130 for receiving the first dust collecting part 50.

[0161] The dust collecting device 100 can release the locking part 55A from the outside of the receiving part 130 when the receiving part 130 receives the first dust collecting part 50. The structure that can contact the locking part 55A from the outside of the receiving part 130 can be any structure, for example, Fig. 20 , Fig.21 As shown in FIG. 1 , a configuration may be formed in which a notch portion 130x formed by cutting out the receiving portion 130 is provided at a position corresponding to the locking portion 55A. According to such a configuration, the locking portion 55A can be operated from the outside of the receiving portion 130 via the notch portion 130x provided in the receiving portion 130. In addition, the electric vacuum cleaner system S may also be replaced with Fig.21 The structure of the notch 130x shown in the figure, or in the Fig.21 On the basis of the structure of the notch 130x shown, a release operation unit is provided on the dust collecting device 100 or the electric vacuum cleaner 1, and the release operation unit is provided on the outside of the receiving portion 130, wherein the release operation unit is used to perform a release operation relative to the locking portion 55A when the receiving portion 130 receives the first dust collecting portion 50. The release operation unit can be operated by releasing the locking portion 55A by pressing the abutted area 57b, or by pressing the locking portion 57a1 in the direction in which the locking portion 57a1 is separated from the opening and closing portion 52c (the locked portion 52k1). In addition, the release operation unit is preferably provided on the first dust collecting portion 50 when provided on the electric vacuum cleaner 1, and is preferably provided on the outside of the receiving portion 130 when provided on the dust collecting device 100. In addition, when the electric vacuum cleaner 1 is removed from the dust collecting device 100, the user can directly release the locking portion 55A. Specifically, the user can press the abutted region 57b or remove the locking portion 57a1 from the opening and closing portion 52c.

[0162] Here, even in the case of forming the structure involved in this modification, as described above, the dust recovery device 100 may not have the second electric blower 120. In this case, a method can be adopted in which a force-applying member 52h is provided to apply force in the direction of opening the opening and closing portion 52c when the locking portion 55A is released, or a method in which the force-applying member 52h is not provided and the opening and closing portion 52c is opened by its own weight. In addition, in the case of forming a structure in which the second electric blower 120 is omitted, the electric vacuum cleaner system S may also be configured as follows: when the opening and closing portion 52c is in an open state, the vibration (air flow) generated by driving the first electric blower 14 is applied to the first dust collecting portion 50 (first dust collecting container 52), and the dust inside the first dust collecting container 52 is promoted to be collected by the second dust collecting portion 110 by the influence of the vibration (air flow).

[0163] In addition, in the above-mentioned embodiment and the illustration of the present modified example, an example is shown in which the abutted portion 57 is supported so as to be rotatable in the up and down directions around the rotating shaft 58, but the present invention is not limited to this. The abutted portion 57 can also be supported by the rotating shaft 58 so as to be rotatable in the horizontal direction (a direction intersecting the axial direction of the main body 10).

[0164] 《Regarding the effects etc. obtained by the electric vacuum cleaner system S and the electric vacuum cleaner 1》

[0165] Hereinafter, for each aspect of the present invention, effects and the like obtained by the electric vacuum cleaner system S and the electric vacuum cleaner 1 illustrated in the above-described respective embodiments will be described.

[0166] [First aspect of the present invention]

[0167] In the past, as disclosed in Japanese Utility Model Publication No. Showa 61-47961, a rechargeable vacuum cleaner was provided, which was configured as follows: a fan motor and a rechargeable secondary battery for supplying power to the fan motor were provided on the vacuum cleaner body, a floor suction port was connected to the suction port of the vacuum cleaner body via an extension pipe, and the center of gravity of the vacuum cleaner body was located further rearward than the center of the grip of the vacuum cleaner body.

[0168] Here, in the electric vacuum cleaner of Patent Document 1, the opening formed in the grip for inserting the hand exists on the opposite side of the secondary battery with respect to the rotating shaft of the fan motor. Although the suction port of the dust collecting part formed in the vacuum cleaner body of the electric vacuum cleaner is consistent with the rotating shaft of the fan motor, when an extension tube is connected to the suction port, the center of gravity of the electric vacuum cleaner is located closer to the extension tube side than the grip. As a result, the electric vacuum cleaner of Patent Document 1 has a structure that the user feels heavy when using it, and there is a problem of poor operability.

[0169] Therefore, an object of the present invention is to realize an electric vacuum cleaner capable of improving operability.

[0170] (1-1) The electric vacuum cleaner 1 of the present invention provided to solve the above-mentioned problems is characterized in that it comprises: a main body 10 having a suction port 38y capable of connecting an extension tube 180 at the lower side in the up-down direction and having an electric blower 14 for generating suction force inside; a dust collecting part 50, which is arranged in parallel with the electric blower 14 in the up-down direction and collects dust; a battery 15a; and a handle 20, which is arranged on the upper side of the up-down direction relative to the main body 10, the main body 10 having a tube 38x, the tube 38x having the suction port 38y, the tube 38x being arranged in parallel with the dust collecting part 50 along a front-to-back direction orthogonal to the up-to-back direction, and being arranged at a front side relative to the dust collecting part 50, and in the front-to-back direction, the handle 20 is located at the front side and the battery 15a is located at the rear side.

[0171] The electric vacuum cleaner 1 of the present invention can hold the handle 20 at a position close to the electric blower 14 and the battery 15a, which are heavy objects, when the extension tube 180 is not connected to the suction port 38y provided on the tube 38x. In addition, the electric vacuum cleaner 1 of the present invention is connected to the extension tube 180 at the suction port 38y provided on the tube 38x, so that the center of gravity of the electric vacuum cleaner 1 exists at the lower side of the up-down direction and the front side of the front-back direction compared with the state where the extension tube 180 is not connected. As a result, compared with the case where the extension tube 180 is not connected, the distance from the handle 20 to the center of gravity of the electric vacuum cleaner 1 of the present invention becomes longer, but compared with the electric vacuum cleaner in which the suction port of the dust collecting part of the vacuum cleaner body and the extension tube exist coaxially under the prior art, the handle 20 can be held at a position close to the upper side relative to the center of gravity. As a result, the electric vacuum cleaner 1 of the present invention can also suppress the sense of weight given to the user when the extension tube 180 is connected. Therefore, according to the present invention, the vacuum cleaner 1 can be realized with high operability while suppressing the feeling of heaviness given to the user in both the state where the extension tube 180 is connected to the tube 38x and the state where the extension tube 180 is not connected to the tube 38x.

[0172] Furthermore, when the extension tube 180 to which the suction piece 190 is also connected is connected to the tube portion 38x, the center of gravity of the electric vacuum cleaner 1 is located closer to the tube portion 38x than the handle portion 20, but the handle portion 20 can be held at an upper side relative to the center of gravity. As a result, the electric vacuum cleaner 1 of the present invention can suppress the feeling of weight given to the user even when the extension tube 180 is connected.

[0173] (1-2) The electric vacuum cleaner 1 of the present invention according to (1-1) above is characterized in that an opening portion 22 for inserting a hand is formed between the handle portion 20 and the main body portion 10, and the opening portion 22 is opened in a manner such that the width in the up-down direction is larger than the width in the front-to-back direction.

[0174] The electric vacuum cleaner 1 of the present invention adopts the above-mentioned structure (1-2), and it is easier to hold when holding the portion extending in the vertical direction than when holding the portion extending in the front-rear direction on the upper end side of the handle portion 20 in the vertical direction. As a result, the electric vacuum cleaner 1 of the present invention becomes an electric vacuum cleaner in which the user can easily and naturally hold the portion extending in the vertical direction of the handle portion 20. Therefore, the electric vacuum cleaner 1 of the present invention can be easily adjusted between the situation where it is held at a position close to the center of gravity and the situation where it is held at a position far from the center of gravity. Therefore, according to the present invention, an electric vacuum cleaner 1 with high operability can be realized.

[0175] (1-3) The electric vacuum cleaner 1 of the present invention involved in any one of the above (1-1) to (1-2) is characterized in that an opening portion 22 for inserting a hand is formed between the handle portion 20 and the main body portion 10, and in the up-down direction, the upper end of the opening portion 22 is located below the upper end of the battery 15a.

[0176] The electric vacuum cleaner 1 of the present invention adopts the above-mentioned structure (1-3), and compared with the case where the upper end of the opening 22 is formed at a position higher than the upper end of the battery 15a, it is possible to suppress the gripping of the handle 20 at a position away from the center of gravity. As a result, the electric vacuum cleaner 1 of the present invention can suppress the feeling of weight given to the user, and has high operability.

[0177] (1-4) The electric vacuum cleaner 1 of the present invention according to any one of (1-1) to (1-3) above is characterized in that the upper end of the battery storage portion 15 that stores the battery 15a is located below the upper end of the handle portion 20 in the up-down direction.

[0178] By adopting the configuration (1-4) described above, the electric vacuum cleaner 1 of the present invention can prevent the battery storage portion 15 from becoming an obstacle when the handle portion 20 is held, compared to a state where the battery storage portion 15 protrudes in the vertical direction relative to the handle portion 20. Thus, the electric vacuum cleaner 1 of the present invention can improve operability.

[0179] (1-5) The electric vacuum cleaner 1 of the present invention involved in any one of the above (1-1) to (1-4) is characterized in that the battery 15a and the handle portion 20 are arranged on the upper side in the up-down direction, with a boundary line passing through the center position of the electric blower 14 and extending along the front-to-back direction as the boundary.

[0180] The electric vacuum cleaner 1 of the present invention adopts the above-mentioned configuration (1-5), and thus has a configuration in which the battery 15a as a weight is arranged near the handle 20. Thus, the electric vacuum cleaner 1 of the present invention allows the handle 20 to be held at a position closer to the center of gravity than when the battery 15a is arranged at a position lower than the center of the electric blower 14. Therefore, the electric vacuum cleaner 1 of the present invention can suppress the feeling of weight given to the user, and has high operability.

[0181] (1-6) The electric vacuum cleaner 1 of the present invention according to any one of the above (1-1) to (1-5) is characterized in that the handle portion 20 and the battery 15a are arranged opposite to each other with a central axis passing through the center position of the electric blower 14 and extending in the up-down direction as a boundary.

[0182] The electric vacuum cleaner 1 of the present invention adopts the above-mentioned configuration (1-6), so that the handle 20 can be held at a position close to the battery 15a which is a heavy object.

[0183] (1-7) The electric vacuum cleaner 1 of the present invention according to any one of (1-1) to (1-6) is characterized in that the tube portion 38x and the handle portion 20 are arranged in parallel in the up-down direction.

[0184] The electric vacuum cleaner 1 of the present invention adopts the above-mentioned structure (1-7), and the handle part 20 can be held at a position above the position of the center of gravity when the pipe part 38x is connected to the extension pipe 180. Therefore, compared with the case where the pipe part 38x and the handle part 20 are not arranged side by side in the vertical direction, the electric vacuum cleaner 1 of the present invention can suppress the feeling of weight given to the user, and has high operability.

[0185] (1-8) The electric vacuum cleaner 1 of the present invention involved in any one of the above (1-1) to (1-7) is characterized in that the dust collecting section 50 centrifugally separates at least a portion of the dust from the air sucked in by the action of the electric blower 14, and the central axis of the dust collecting section 50 is consistent with the central axis of the electric blower 14.

As a result, the electric vacuum cleaner system S of the present invention can more easily collect dust attached to the structure 54 and the like into the dust collecting device 100.

[0218] (3-6) The electric vacuum cleaner system S of the present invention involved in any one of the above (3-1) to (3-5) is characterized in that the main body 10 has: a suction port 38y, which is connected to the first dust collecting part 50; an external exhaust port, which discharges the air sucked by the first electric blower 14 to the outside; and a gate part, which is used to open and close the external exhaust port.

[0222] However, since the electric vacuum cleaner of the above patent document opens and closes the valves of each dust box arranged on the vacuum cleaner body side and the installation base side by the suction force of the vacuum cleaner body, there is a problem that the opening and closing degree of the valve is affected by the suction performance of the vacuum cleaner body side.

[0223] Therefore, an object of the present invention is to realize an electric vacuum cleaner system capable of easily collecting dust on the electric vacuum cleaner side.

[0224] (4-1) The electric vacuum cleaner system S of the present invention is characterized by comprising: an electric vacuum cleaner 1 having a main body 10 and a first dust collecting part 50 for collecting dust, the main body 10 having a first electric blower 14 for generating suction force; and a dust collecting device 100, which collects dust from the electric vacuum cleaner 1 by being connected to the first dust collecting part 50 and having a second dust collecting part 110 for collecting dust, the first dust collecting part 50 having a dust collecting container (first dust collecting container 52) for storing dust; The opening and closing portion 52c can open and close the waste port 52b at the bottom of the dust collecting container when the first dust collecting portion 50 is installed on the main body 10; and the locking portion 55A can lock the opening and closing portion 52c in a closed state.
