  In the following description, dust and other dust may be collectively referred to simply as "dust". Also, air containing dust may be referred to as "dust-containing air". And air from which dust is removed may be called "clean air"

  A vacuum cleaner 1 according to Embodiment 1 of the present invention is a cordless type vertical vacuum cleaner. As shown in FIG. 1, the vacuum cleaner 1 includes a main body 3, a tube 4 and a suction tool 5 as main components. As shown in FIGS. 2 and 3, the main body 3 includes a handle 15, an outer shell 16 and a dust collector 17. The handle 15 is a part that the user holds by hand while using the vacuum cleaner 1. The user can hold the main body 3 of the vacuum cleaner 1 by holding the handle 15.

  The outer shell portion 16 is a member that forms an outer shell, that is, an outer cover of the main body 3. An electric blower 23 and a battery unit 19 (not shown in FIGS. 2 and 3) are incorporated in the outer shell portion 16 of the main body 3. The electric blower 23 is for generating suction air of the vacuum cleaner 1. The battery unit 19 includes a battery for driving the electric blower 23.

  The outer shell 16 includes a case 18 and a connecting pipe 20. The connection pipe portion 20 is a hollow cylindrical member to which the pipe 4 is detachably connected. The connection pipe portion 20 has a connection port 29 for sucking in dust. The connection port 29 is an opening formed at one end of the connection pipe portion 20. Inside the connection pipe portion 20, there is formed an air passage for guiding the air flow of the dust-containing air having passed through the connection port 29 to the dust collection portion 17. At the other end of the connection pipe portion 20, one end of the handle 15 is disposed so as to be continuous in appearance. An operation unit 22 is provided on the other end side of the handle 15.

  The dust collection unit 17 is for collecting the dust in the dust-containing air sucked into the main body 3 by the suction air generated by the electric blower 23. As shown in FIG. 4, the dust collection unit 17 is detachably attached to the main body 3. As shown in FIG. 5, the dust collection unit 17 has a columnar appearance as a whole. The dust collection unit 17 according to the first embodiment has a cyclone separation device. The cyclone separation device is a device that swirls the dust-containing air inside with the air flow generated by the electric blower 23 to separate the dust from the dust-containing air.

  As shown in FIG. 2, the outer shell part 16 includes an exhaust part 21. The exhaust part 21 is an opening formed in the outer shell part 16. The air flow from which dust has been removed by the dust collection unit 17 is discharged from the exhaust unit 21 to the outside of the main body 3.

  The electric blower 23 is driven in response to an operation on the operation unit 22 provided on the handle 15. When the electric blower 23 is driven, a suction force acts on the inside of the dust collection portion 17 and the connection pipe portion 20, and dust-containing air is sucked from the connection port 29. The dust-containing air sucked into the connection port 29 passes through the connection pipe portion 20 and is taken into the inside of the dust collection portion 17. In the dust collecting unit 17, dust is separated from the dust-containing air. The clean air discharged from the dust collection unit 17 passes through the electric blower 23. The clean air that has passed through the electric blower 23 is discharged from the exhaust unit 21 to the outside of the main body 3.

  Next, the configuration of the dust collection unit 17 will be described. As shown in FIG. 6, the dust collection part 17 is provided with a filter part 81, an inflow part case 82, a guide part 83, a discharge part 84, a conical part 85, a partition part 86 and a dust collection container 87 as main components. ing. The dust collection portion 17 has a cylindrical shape as an appearance. The dust collecting portion 17 is longer in the height direction, that is, in the direction perpendicular to the circumferential direction than in the circumferential direction. In other words, the dust collection portion 17 has a longitudinal axis in the direction perpendicular to the circumferential direction.

  As shown in FIGS. 7 and 8, the inflow port case 82 is formed with an inflow port 101. The side surface of the inflow portion case 82 is composed of a circular arc surface 102 and a straight surface 103. The inflow portion case 82 has a D-shape in top view, as particularly shown in FIG. The inlet 101 is disposed on the straight surface 103. The inlet 101 is an opening for introducing dust-containing air into the inside of the dust collection unit 17. A lever portion 94 is provided in the inflow portion case 82. The lever portion 94 is a portion engaged with a case portion 18 described later of the main body 3 when the dust collection portion 17 is attached to the main body 3.

  The filter portion 81 is detachably accommodated in the upper portion of the inflow portion case 82. As shown in FIG. 7, the filter unit 81 includes a frame 92, a filter 91 and a first packing 93. The frame 92 has a D-shape similar to the inflow portion case 82 in top view. The first packing 93 is disposed on the upper periphery of the frame 92. The first packing 93 is in close contact with the later-described case portion 18 of the main body 3 during the suction operation of the main body 3.

  The guide portion 83 is a member for guiding the dust-containing air flowing from the inflow port 101 of the inflow portion case 82 to the conical portion 85. The guide part 83 is provided with the guide plate 106, the top face part 107, and the 2nd packing 108, as shown in FIG.8 and FIG.9. The guide plate 106 is a portion for guiding the dust-containing air, which has flowed in from the inflow port 101, to a swirl chamber 111 described later. The top surface portion 107 is an upper surface of a swirl chamber 111 described later in a state where the dust collection portion 17 is properly assembled. The second packing 108 is disposed on the upper periphery of the top surface portion 107. The second packing 108 is in close contact with the inner wall of the inflow portion case 82 in a state where the dust collection portion 17 is properly assembled. The top surface portion 107 and the second packing 108 prevent the dust-containing air in the swirl chamber 111 described later from leaking out to the filter portion 81 side without passing through the discharge portion 84 described later.

  The conical portion 85 is a member mainly serving as a side wall of the swirl chamber 111. The conical portion 85 is disposed below the guide portion 83 in a state where the dust collection portion 17 is properly assembled. The swirl chamber 111 is a chamber for swirling the dust-containing air flowing in from the inflow port 101 to centrifugally separate the dust from the dust-containing air. The conical portion 85 has an inverted conical shape in its main part. The side wall of the conical portion 85 is formed with a first opening 112. At the bottom of the conical portion 85, a second opening 113 is formed. The bottom of the conical portion 85 corresponds to the apex of the inverted conical shape described above. The first opening 112 and the second opening 113 are openings for discharging the dust centrifugally separated from the dust-containing air to the outside of the swirl chamber 111.

  The discharge portion 84 is disposed inside the conical portion 85 with the dust collection portion 17 properly assembled. The discharge portion 84 has a cylindrical or conical shape, or a shape combining a cylindrical and a conical shape. The discharge part 84 is formed with a plurality of fine holes.

  The dust collection container 87 has a bottomed cylindrical shape. The dust collection container 87 is disposed outside the conical portion 85 with the dust collection portion 17 properly assembled. A recess 88 is formed on the outside of the bottom surface of the dust collection container 87. The lever portion 94 and the recess portion 88 are disposed on the opposite side of the center of the dust collection portion 17 in a state where the dust collection portion 17 is properly assembled. At the upper end portion of the inner wall of the dust collection container 87, a rotary engagement portion 89 is formed. The conical portion 85 and the dust collection container 87 are detachably combined via the rotary engagement portion 89. As described above, by providing the concave portion 88 on the bottom surface and the rotary engaging portion 89 on the inner wall, it is possible to make the side wall which is the design surface of the dust collection container 87 have no unevenness. And by eliminating the unevenness of the side surface of the dust collection container 87, the design is excellent.

  A space inside the dust collection container 87 and outside the conical portion 85 is a dust collection chamber. The dust collection chamber is a space for collecting the dust centrifugally separated from the dust-containing air in the swirl chamber 111. A partition 86 is disposed inside the dust collection container 87 and outside the conical part 85. The dust collection chamber is divided into two parts of the first dust collection chamber 114 and the second dust collection chamber 115 by the partition part 86. The first dust collection chamber 114 is disposed outside the second dust collection chamber 115. Therefore, the second dust collection chamber 115 is disposed inside the first dust collection chamber 114. The first dust collection chamber 114 communicates with the swirl chamber 111 through the first opening 112. The second dust collection chamber 115 communicates with the swirl chamber 111 via the second opening 113.

  The dust collection container 87 may be made of a transparent material at least in part. By doing this, the dust collection container 87 has excellent visibility from the outside, and the accumulated amount of dust can be confirmed, so it is easy to grasp the waste disposal time. The dust collection container 87 is longer in the height direction, ie, in the direction perpendicular to the circumferential direction than in the circumferential direction. In other words, the dust collection container 87 has a longitudinal axis in a direction perpendicular to the circumferential direction. Further, the dust collection container 87 has a central axis in parallel with the longitudinal axis.

  The discharge part 84, the conical part 85, and the dust collection container 87 are all circular in cross section perpendicular to their central axes. And each central axis of discharge part 84, cone part 85, and dust collection container 87 is arranged so that all may become parallel. Although the central axes of the discharge portion 84 and the conical portion 85 coincide with each other, they do not coincide with the central axis of the dust collection container 87.

  As described above, when the electric blower 23 of the main body 3 operates, suction air is generated, and dust-containing air is drawn into the dust collection unit 17 from the connection port 29 and the connection pipe unit 20. At this time, the dust-containing air flows into the dust collection unit 17 from the inflow port 101. The dust-containing air that has passed through the inflow port 101 flows into the swirl chamber 111 shown in FIG. 8 through the inflow air path 104 shown in FIG. At this time, the dust-containing air flows from the tangential or circumferential direction into the swirl chamber 111 along the inner surface of the conical portion 85, that is, the side wall forming the swirl chamber 111.

  The air that has flowed into the swirl chamber 111 rotates in a preset direction along the side wall forming the swirl chamber 111 and forms a swirling air flow in the swirl chamber 111. The swirling air flows downward by its path structure and gravity while forming a forced vortex region near the central axis and a free vortex region outside the forced vortex region.

  Centrifugal force acts on the air in the swirl chamber 111, that is, the dust contained in the swirl airflow described above. For example, relatively bulky waste α such as fiber waste and hair falls while being pressed against the cylindrical portion by the acting centrifugal force. Therefore, the dust α passes through the first opening 112 when the height of the first opening 112 is reached. The dust α that has passed through the first opening 112 is sent to the first dust collection chamber 114. In the first dust collection chamber 114, a part of the swirling airflow also slightly flows in with the dust α. The inflowing air swirls in the first dust collection chamber 114.

  The dust that has not entered the first dust collection chamber 114 from the first opening 112 moves downward while being swirled by the air flow in the swirl chamber 111. A relatively bulky waste β such as sand waste and fine fiber waste passes through the second opening 113. Then, the dust β falls into the second dust collection chamber 115 and is captured.

  When the swirling air flow in the swirling chamber 111 reaches the lowermost portion of the swirling chamber 111, the traveling direction thereof is changed upward and rises along the central axis of the swirling chamber 111. The dust α and the dust β are removed from the air forming the updraft. The clean air from which the waste α and the waste β have been removed passes through the fine opening of the discharge unit 84 and flows out of the turning chamber 111. The air that has passed through the discharge unit 84 passes through the filter 91 and is discharged to the outside of the dust collection unit 17. The filter 91 may not be provided because large and small dusts can be separated from the air flow in the conical portion.

  Thereafter, the clean air passes through the electric blower 23 in the shell 16. Then, the clean air is blown out of the exhaust unit 21 to the outside of the main body 3. At this time, the blow-off direction of air from the exhaust unit 21 is parallel to the connection pipe unit 20.

  Next, the configuration of the tubular body 4 will be described with reference to FIGS. 10 to 12. The tube 4 is a hollow tubular member having a linear outer shape along the longitudinal axis. One end side of the tube 4 is detachably connected to the main body 3. The other end side of the tube 4 is detachably connected to the suction tool 5. The pipe 4 includes a pipe portion 11 and a pipe cover portion 12. The longitudinal axis of the tube 4 is the longitudinal axis of the internal air passage of the tube 4. The internal air path is a straight air path. The outer shape of the tube 4 has a bar-like shape.

  The pipe portion 11 includes a pipe 11a and a first engaging portion 11b. The pipe 11a is a hollow tubular member having a linear outer shape along the longitudinal axis. The first engaging portion 11 b is a protrusion formed on the above-mentioned other end side of the pipe 11 a. The first engagement portion 11 b is used to engage the tube 4 and the suction tool 5. The pipe cover portion 12 is attached to the lower portion of the pipe portion 11. The pipe cover portion 12 has a linear outer shape along the longitudinal axis. The cross section perpendicular to the longitudinal axis of the pipe cover 12 has an arc shape.

  A first latch portion 61 and a first terminal portion 64 are provided at the above-described one end side of the tube body 4. The first latch portion 61 is disposed on the opposite side of the pipe cover portion 12 at the above-described one end side of the tube 4. The first latch portion 61 holds the connected state of the connection pipe portion 20 of the main body 3 and the pipe body 4 and enables the user to easily release the connection. That is, the first latch portion 61 is a first connection holding means for holding the state in which the tube 4 and the main body 3 are connected.

  The first latch portion 61 includes a first latch 62 and a first cover latch 63. When the above-mentioned one end side of the tube 4 is inserted into the connection tube 20 of the main body 3, the first latch 62 is hooked on the connection tube 20, and the coupled state of the connection tube 20 and the tube 4 is maintained. When the user presses the first latch 62, the connection state of the connection pipe portion 20 and the pipe body 4 is released. The tube 4 can be removed from the main body 3 by moving the tube 4 away from the main body 3 in a state where the connection between the connection tube portion 20 and the tube 4 is released.

  That is, the first latch 62 is a first connection release operation unit for releasing the connection by the first connection holding unit described above. And this 1st connection release operation part is provided not in the main body 3 but in the pipe 4 side. In this way, the user can remove the tubular body 4 from the main body 3 while holding the handle 15 of the main body 3 with one hand and pressing the first latch 62 with the other hand.

  The first terminal portion 64 is a relay component for energizing the main body 3 and the suction tool 5. The first terminal portion 64 is disposed between the pipe portion 11 and the pipe cover portion 12 on the aforementioned one end side of the pipe 4. The first terminal portion 64 is connected to a lead (not shown). The lead wire is disposed between the pipe portion 11 and the pipe cover portion 12 over the aforementioned other end side of the pipe 4.

  Next, the configuration of the suction tool 5 will be described with reference to FIGS. 13 to 17. The suction tool 5 includes a suction port body 14 and a connecting portion 13. The suction tool 5 is connected to the above-mentioned other end side of the pipe 4 via the connection portion 13.

  As shown in FIG. 14, in plan view, the shape of the suction port body 14 has a rectangular shape. The cleaning direction in the suction port body 14 is referred to as the short side direction of the suction port body 14. In a plan view, a direction perpendicular to the short direction of the suction port body 14 is referred to as the longitudinal direction of the suction port body 14. The length in the longitudinal direction (maximum length) of the suction port body 14 is W, and the length in the lateral direction (maximum length) is L. The length W in the longitudinal direction of the suction port body 14 is longer than the length L in the lateral direction of the suction port body 14.

  The suction port body 14 is provided with two front wheels 47 and two rear wheels 48 at the bottom. The front wheel 47 and the rear wheel 48 are disposed at symmetrical positions from the longitudinal center of the suction port body 14 described above. The front wheel 47 and the rear wheel 48 make rolling contact with the surface to be cleaned during cleaning. A suction port 46 is formed on the bottom surface of the suction port body 14. The suction port 46 is an opening facing downward.

  The suction tool 5 is for cleaning the surface to be cleaned. The surface to be cleaned is, for example, a surface extending parallel to a horizontal surface such as a floor surface. At the time of cleaning, the suction tool 5 is installed on the surface to be cleaned in a cleanable posture. The cleanable posture is, for example, a posture when the suction port body 14 alone is installed on the surface to be cleaned in a state where no external force from any other than the surface to be cleaned is applied. In the cleanable posture, for example, three or more front wheels 47 and rear wheels 48 are in contact with the surface to be cleaned. In the cleanable posture, for example, when the suction tool 5 is moved back and forth, the front wheel 47 and the rear wheel 48 are in rolling contact with the surface to be cleaned. In the cleanable posture, for example, most of the bottom surface of the suction port body 14 is disposed parallel to the surface to be cleaned.

  The suction port body 14 includes a rotating brush 49 and a rotating brush motor (not shown). The rotating brush 49 is disposed so as to face the suction port 46 from above the suction port 46. The gear of the rotating brush motor is rotated by the power supplied from the main body 3 through the tube 4, and the rotation is transmitted by a belt or the like to rotate the rotating brush 49. By rotating the rotating brush 49, dust on the surface to be cleaned is scraped up.

  The suction port body 14 includes a safety switch 50. The safety switch 50 is for detecting whether the suction port body 14 is on the surface to be cleaned. The safety switch 50 includes a wheel 50a and an elastic member (not shown). The elastic member is, for example, a spring. The wheel 50a is mounted movably in the vertical direction. The wheel 50 a is movable to above the front wheel 47 and the rear wheel 48.

  When the suction port body 14 separates from the surface to be cleaned, the wheel 50 a projects downward from the front wheel 47 and the rear wheel 48 by the elastic member. In this state, the safety switch 50 detects that the suction port 14 is not on the surface to be cleaned. When the safety switch 50 detects that the suction port 14 is not on the surface to be cleaned, the rotating brush 49 does not rotate. When the suction port 14 is on the surface to be cleaned, the surface to be cleaned pushes the wheel 50 a to a position equivalent to the front wheel 47 and the rear wheel 48. In this state, the safety switch 50 detects that the suction port body 14 is on the surface to be cleaned. When the safety switch 50 detects that the suction port 14 is on the surface to be cleaned, the rotating brush 49 rotates.

  One end of the connection portion 13 is attached to a middle portion in the longitudinal direction of the suction port body 14 and to one side in the short side direction via a joint structure. The other end side of the pipe body 4 is detachably connected to the other end side of the connecting portion 13.

  A second latch portion 41 and a second terminal portion 44 are provided on the other end side of the connecting portion 13 described above. The second latch portion 41 holds the coupling state of the tube 4 and the coupling portion 13 and allows the coupling to be easily released by the operation of the user. That is, the 2nd latch part 41 is the 2nd connection holding means for holding the state where tube 4 and suction tool 5 were connected.

  The second latch portion 41 includes a second latch 42 and a second cover latch 43. When the other end of the connecting portion 13 is inserted into the other end of the pipe 4, the second latch 42 is engaged with the first engaging portion 11 b of the pipe 4, and the connecting portion 13 and the pipe 4 The binding state with is maintained. When the user presses the second latch 42, the coupling state of the coupling portion 13 and the tubular body 4 is released. The suction tool 5 can be removed from the pipe body 4 by moving the suction tool 5 away from the pipe body 4 in a state where the coupling portion 13 and the pipe body 4 are released.

  That is, the second latch 42 is a second connection release operating unit for releasing the connection by the second connection holding unit described above. And this 2nd connection release operation part is provided in the suction tool 5 side instead of the pipe body 4. By doing this, the user removes the suction tool 5 from the tube 4 while holding the handle 15 or the tube 4 of the main body 3 with one hand and pushing the second latch 42 with the other hand. be able to.

  The second terminal portion 44 is a relay component for energizing the main body 3 and the suction tool 5. The second terminal portion 44 is connected to a lead (not shown). This lead is connected to the rotating brush motor and the safety switch 50.

  The aforementioned joint structure of the connecting portion 13 has a plurality of rotation axes which are not parallel to each other, and can be independently rotated in the respective directions about the plurality of rotation axes. The joint structure of the connecting portion 13 has, for example, a first rotation axis X indicated by a black circle (●) in FIGS. 13 and 16 and a second rotation axis Y indicated by a dashed dotted line. The first rotation axis X is a rotation axis parallel to the longitudinal direction of the suction port body 14 in a side view. The second rotation axis Y is a rotation axis which is inclined with respect to the horizontal direction in the side view and parallel to the short direction in the top view. The first rotation axis X and the second rotation axis Y are in the relationship of the position of twist.

  Even when the connecting portion 13 rotates about the first rotation axis X and the second rotation axis Y, the opening direction of the suction port 46 is maintained. That is, the pipe 4 connected to the connecting portion 13 can be inclined with respect to the suction port body 14 in a preset angle range in a state in which the opening direction of the suction port 46 is maintained. Thus, the connecting portion 13 connects the suction tool 5 and the pipe body 4 so that the angle formed by the bottom surface of the suction tool 5 and the longitudinal axis of the pipe body 4 can be changed within a preset angle range.

  As shown in FIG. 17, a rotation angle of the connecting portion 13 with respect to the suction port body 14 with the first rotation axis X as a center is set as a first angle α. When the direction parallel to the bottom surface of the suction tool 5 and in which the connecting portion 13 is disposed as viewed from the suction port body 14 is the first angle α = 0 °, the first angle α is, for example, 0 ° It can be in the range of 90 °. More preferably, the first angle α may be in the range of 0 ° to 92 °. Therefore, the angle range where the bottom surface of the suction tool 5 and the longitudinal axis of the tube 4 are parallel is included in the above-mentioned angle range. Further, the angle range mentioned above includes the angle at which the bottom surface of the suction tool 5 and the longitudinal axis of the tube 4 are at right angles. Note that FIG. 16 shows the first angle α = 0 °, and FIG. 17 shows the first angle α = 92 °.

  Further, as shown in FIG. 15, the rotation angle of the connecting portion 13 with respect to the suction port body 14 with the second rotation axis Y as a center is set as a second angle β. When a direction perpendicular to the longitudinal direction of the suction port body 14 is a second angle β = 0 °, the second angle β can range, for example, from −90 ° to + 90 °. However, since FIG. 15 is viewed from a direction not orthogonal to the second rotation axis Y, the apparent second angle β in FIG. 15 is not −90 ° to + 90 °. When the first angle α = 0 ° and the second angle β = ± 90 °, the tip of the connecting portion 13 reaches below the bottom surface of the suction tool 5.

  When the main body 3, the tubular body 4 and the suction tool 5 are integrally connected, the connecting portion 13 and the tubular body 4 are at the front, even when the first rotation axis X and the second rotation axis Y are at any angle. It is disposed above the lower ends of the wheels 47 and the rear wheels 48. In addition, when the second angle β is 0 °, the main body 3 is disposed above the lower ends of the front wheel 47 and the rear wheel 48 regardless of the first rotation axis X.

  When the vacuum cleaner 1 configured as described above is used as a stick-type vacuum cleaner by connecting the main body 3, the tube 4 and the suction tool 5 so as to be integrated, for example, as shown in FIG. The user grips the handle 15 of the main body 3 and cleans the floor surface so that the longitudinal direction of the tube 4 is in the oblique direction. Also, for example, when cleaning the ceiling surface etc., as shown in FIG. 18, with the main body 3 and the pipe 4 connected and the suction tool 5 removed, the handle 15 of the main body 3 is gripped, So that the longitudinal direction of the

  Furthermore, the vacuum cleaner 1 which concerns on Embodiment 1 of this invention can take two forms of "the upright form" and the "flat form" which are described below. The upright form is a form in which the main body 3, the tube 4 and the suction tool 5 are connected integrally so as to make the first angle α = 90 ° or more and the second angle β = 0 °. The example of the upright form of the vacuum cleaner 1 is shown to FIGS. 19-22. In this example, the first angle α = 92 °.

  In the upright configuration, the center of gravity of the main body 3 is disposed closer to the front end side of the suction port body 14 than the tube 4, the first rotation axis X, or the rear wheel 48. Thus, the upright vacuum cleaner 1 can stand on its own. Moreover, as shown in FIG.20 and FIG.21, the vacuum cleaner 1 has symmetry as an external appearance. Furthermore, as shown in FIGS. 19 and 22, the tube 4 and the main body 3 can be disposed on the front side of the rear end of the suction tool 5. Further, in the upright form, on the projection plane parallel to the bottom surface of the suction tool 5, all of the electric blower 23, the control unit 24 and the dust collection unit 17 are arranged so as not to overlap with the battery unit 19.

  The flat form is a form in which the main body 3, the tube 4 and the suction tool 5 are connected integrally so as to make the first angle α = 0 ° and the second angle β = 0 °. In other words, in the flat form, the main body 3, the pipe 4 and the suction tool 5 are integrally connected, and the bottom surface of the suction tool 5 and the pipe 4 face downward with the bottom of the suction tool 5 facing downward. It is the form which made the longitudinal axis parallel.

  The flat form of the vacuum cleaner 1 is shown in FIG. 23 and FIG. As shown in these figures, in the flat configuration, the lowermost portion of the main body 3 and the lowermost portion of the tube 4 are arranged in the same vertical direction as the lowermost portion of the suction tool 5 or above the lowermost portion of the suction tool 5 . Here, specifically, the lowermost portion of the suction tool 5 is one of the front wheel 47 and the rear wheel 48. Further, in the flat configuration, the lowermost portion of the main body 3 is disposed in the same vertical direction as the lowermost portion of the tube 4 or above the lowermost portion of the tube 4.

  For this reason, when cleaning the gap in the low position between the furniture and the floor surface, the interior of the gap is cleaned without interference between the portion of the tube 4 or the portion of the main body 3 and the floor surface. Cheap. That is, since the height from the floor surface to the suction tool 5 and the tube 4 is kept low and the low place such as the lower part of the sofa can be easily cleaned, the operability of the electric vacuum cleaner 1 can be improved. In addition, the suction port body 14 can be inserted further into the lower part. Under the present circumstances, since it can be set as a flat form only by rotating centering around the 1st rotating shaft X, a low position can be cleaned without twisting a wrist.

  In addition, the outer periphery of the lower surface of the tube 4 has a linear shape on a projection plane perpendicular to the bottom surface of the suction tool 5 and parallel to the longitudinal axis of the tube 4 in a flat form. For this reason, even if there are irregularities or other objects on the floor surface, the tube 4 is less likely to be caught by the irregularities or other objects, and the operation can be improved.

  Further, the first connection holding means described above and the second connection holding means described above are disposed above the central axis of the tubular body 4, that is, the vertical center of the internal air passage in the flat configuration. For this reason, the button of the 1st latch part 61 and the 2nd latch part 41 touches a to-be-cleaned surface accidentally in flat form, and the connection of the suction tool 5 and the pipe 4 or the pipe 4 and the main body 3 is released. You will not be

  The tube 4 is provided with a first terminal 64 for supplying power to the rotary brush motor of the suction tool 5, the first terminal 64 being arranged at the lower part of the tube 4 in a flat configuration. For this reason, the outer shape of the pipe cover portion 12 at the lower part of the tube 4 has no unevenness, and the tube 4 is not easily caught by the unevenness and other objects on the floor surface. Moreover, the external shape in the cross section perpendicular | vertical to the longitudinal axis of the pipe body 4 of the pipe body 4 which consists of the pipe part 11 and the pipe cover part 12 is constant. Therefore, the appearance is not impaired.

  Next, a configuration including the inside of the main body 3 will be described with reference to FIGS. 24 and 25. Inside the main body 3, the battery unit 19, the electric blower 23, and the control unit 24 described above are accommodated. The control unit 24 includes a circuit for controlling the operation of the electric blower 23 and the like.

  Next, the battery unit 19 will be described with reference to FIGS. 26 to 31. The battery unit 19 includes a battery 26 and a battery case 25 that houses the battery 26. A part of the cross section of the battery case 25 has a rounded triangular shape as an appearance. The battery 26 comprises, for example, a plurality of secondary batteries. The battery 26 comprises, for example, six secondary batteries. One secondary battery has, for example, a cylindrical shape.

  The battery 26 is composed of a first battery group 27 and a second battery group 28. The first battery group 27 and the second battery group 28 each include, for example, three secondary batteries. The first battery group 27 is fixed by the first holder 31. The second battery group 28 is fixed by the second holder 32. The first holder 31 and the second holder 32 bring the secondary batteries close to each other and arranged in a rounded triangular prism. The secondary batteries constituting the first battery group 27 and the second battery group 28 all face in the same direction. The first battery group 27 and the second battery group 28 are disposed in such a manner that their end faces face each other. The central axes of the individual secondary batteries whose end faces face each other coincide.

  The battery unit 19 configured as described above is disposed in the lower part of the case portion 18. Further, the battery unit 19 is disposed on an extension of the central axis of the connection pipe portion 20. Furthermore, the battery unit 19 and the dust collection unit 17 partially overlap in a flat form in a projection plane parallel to the bottom surface. By arranging in this way, the main body 3 can be made compact, and the height of the main body 3 in the flat form can be kept low.

  The external shape of the battery unit 19 and the dust collection unit 17 has a columnar shape. The central axes of the battery unit 19, the dust collection unit 17 and the connection tube 20, and the rotation axis of the electric blower 23 are all parallel. By arranging in this way, the whole of the main body 3 can be further made compact, and the height of the main body 3 in the flat form can be kept low. In addition, since there is no need to provide an extra bending air path, the pressure loss of the air flow is small.

  The handle 15 is continuously disposed from the side opposite to the connecting pipe portion 20 of the main body 3 from the side opposite to the connecting pipe portion 20 in the flat form to the upper side of the main body 3. A space is formed between the handle 15 and the outer shell 16. The finger of the hand holding the handle 15 can be inserted into this space. Thus, the handle 15 is continuously disposed from the upper end to the lower end of the outer shell 16. And, for example, the upper end and the lower end of the handle 15 are parallel. Also, for example, the middle part of the handle 15 is curvedly connected to the upper end and the lower end of the handle 15. For this reason, according to the scene where cleaning is performed, the user can secure an appropriate grip point. For example, by holding the wrist in a natural state without bending it, the load on the wrist and hand is reduced. In addition, the exhaust part 21 is arrange | positioned in the flat form in the position which becomes the front side rather than the front end of the handle 15. As shown in FIG.

  Further, a part of the handle 15 is disposed rearward of the rear end portion of the case portion 18. The portion of the handle 15 on the rear side of the case portion 18 can hold the user's forearm along the surface to be cleaned without bending the wrist. Therefore, when cleaning the horizontal plane, the user's load is reduced because the forearm can be easily cleaned by back and forth movement.

  The electric blower 23, the battery unit 19, the dust collection unit 17, and the handle 15 are disposed above the lowermost portion of the connection pipe unit 20 in a flat form. In addition, at least one of the electric blower 23, the battery unit 19, and the control unit 24 and the handle 15 overlap in a flat form on a projection plane parallel to the bottom surface of the suction tool 5. Further, the tip of the upper portion of the main body 3 of the handle 15 overlaps with the electric blower 23 on a projection plane parallel to the bottom surface of the suction tool 5 in a flat form. In this way, the weight of the electric blower 23, the battery unit 19, and the control unit 24 can be reduced by holding the front of the handle 15 as necessary while keeping the height of the main body 3 in the flat form low. Support with less power.

  Further, a part of the handle 15 is disposed on the extension of the battery unit 19. For this reason, the battery unit 19 which is a heavy load is disposed at a position close to the hand of the user who holds the handle 15. Therefore, for example, when twisting the wrist and rotating the suction tool 5 to the left and right, etc., since the heavy load is near the hand, the load is hardly applied to the hand, and the operability is improved.

  The dust collection unit 17 is disposed adjacent to the upper side of the connection pipe 20 and along the connection pipe 20. Further, the dust collection unit 17 is attached to the front of the case unit 18. Under the present circumstances, the recessed part 88 of the dust collection container 87 bottom part engages with the convex part 36 of the upper part of the connection pipe part 20. As shown in FIG. Then, the dust collection portion 17 is rotated with the contact point of the recess 88 and the connection pipe portion 20 as a fulcrum, and the lever 95 of the lever portion 94 is hooked on the case portion 18 side. It is fixed.

  In the flat configuration, the foremost portion of the dust collection portion 17 is disposed rearward of the foremost portion of the connection pipe portion 20. For this reason, when using the vacuum cleaner 1 as a handy type only with the main body 3 without using the pipe 4 and the suction tool 5, the dust collection part 17 is hard to contact the surface to be cleaned, and the cleaning property is improved. Do. Further, also in the flat form, the distance from the foremost part of the suction tool 5 to the bottom of the dust collection portion 17 becomes long, and it becomes easier to clean the lower part having a depth.

  In addition, the dust collection unit 17 is provided in front of the electric blower 23. And it is good to make at least one copy of dust collection part 17 which becomes upper side with a flat form transparent. By doing this, the user can easily check the amount of dust collected in the dust collection unit 17 when cleaning. On the other hand, making at least a part of the dust collecting part 17 opaque makes it difficult for the dust collected in the dust collecting part 17 to be visible to the outside, for example, when the electric vacuum cleaner 1 is in an upright form when not in use. Can.

  The case portion 18 of the main body 3 has a cylindrical shape. Further, in a state where the dust collection part 17 is attached to the main body 3, the dust collection part 17 has a cylindrical shape having the same diameter as that of the case part 18. And the external shape which unified case part 18 and dust collection part 17 is cylindrical. For this reason, it can be made into the unified appearance.

  The vacuum cleaner system 1000 which concerns on Embodiment 1 of this invention is equipped with the vacuum cleaner 1 and the stand 2 which were comprised as mentioned above, as shown in FIG.30 and FIG.31. The stand 2 is placed, for example, on the floor of the living room. The vacuum cleaner 1 is removed from the stand 2 at the time of use. The stand 2 is, for example, a charging stand. By placing the vacuum cleaner 1 on the stand 2 when not in use, the battery unit 19 of the vacuum cleaner 1 can be charged.

  The stand 2 includes a base portion 201, a support portion 202, and a main body support portion 203. The base portion 201 is a base portion disposed at the lowermost position of the stand 2. The support portion 202 is formed vertically upright from the upper surface of the base portion 201. The main body support portion 203 is fixed to the middle portion of the support portion 202.

  When the vacuum cleaner 1 is placed on the stand 2, the front end side of the suction tool 5 and the side on which the dust collection portion 17 is disposed are viewed from the pipe 4 and the connection pipe portion 20 toward the support portion 202 of the stand 2. It is directed to. That is, the stand 2 supports the main body 3 of the vacuum cleaner 1 in the upright form described above from the front end side of the suction tool 5. After the cleaning is completed, the user can place the vacuum cleaner 1 on the stand 2 while moving the vacuum cleaner 1 to the front side of the suction tool 5 as it is. The suction device 5 is supported by the base portion 201 of the stand 2 when the vacuum cleaner 1 is attached to the stand 2.

  In the present embodiment, an example in which the dust collection unit 17 has a cyclone separation device for performing centrifugal separation has been described. However, if the dust collection unit 17 separates dust from dust-containing air and stores the separated dust, the method of separating and storing dust is not limited to this. For example, dust and air may be separated by a filter without performing centrifugation. Also, it may be a so-called paper pack type. According to the present embodiment, it is possible to clean a low place having a depth without being limited to the dust collection method. However, the dust collection portion 17 in the first embodiment has a cylindrical shape, and dust-containing air is made to flow in along the tangential direction or the circumferential direction of the cylindrical shape. Then, the dust collection portion 17 is formed along the connection pipe portion 20. In the centrifugal separation method, the pressure loss can be reduced and dust can be efficiently separated by introducing dust-containing air along the tangential or circumferential direction. Therefore, dust can be separated in a compact and efficient manner by causing the dust-containing air to flow in the dust collecting portion 17 along the tangential direction or the circumferential direction, and connecting the connection pipe portion 20 along the dust collecting portion 17. The electric vacuum cleaner 1 which can be obtained is obtained.

  In the above, the terms longitudinal axis and central axis are used. With respect to these terms, the central axis does not necessarily limit the outer shape to a complete circle, and the outer shape may have, for example, irregularities for engagement or fitting. The central axis may also include an axis at the center in the width direction or at the center in the depth direction. That is, the central axis is also taken as a longitudinal axis that is at the center in the width direction or at the center in the depth direction. In short, the central axis refers to the axis of the approximate center of an object having a longitudinal axis.

Second Embodiment
FIG. 32 is a side view of a main body of a vacuum cleaner according to Embodiment 2 of the present invention. Hereinafter, the vacuum cleaner which concerns on this Embodiment 2 is demonstrated focusing on difference with Embodiment 1. FIG.

  In the electric vacuum cleaner according to Embodiment 2 of the present invention, as shown in FIG. 32, the handle 15 is disposed on the opposite side of the connection pipe portion 20 of the main body 3 in the flat form. More specifically, the handle 15 is provided in parallel with the lower end and the upper end of the handle 15 continuously disposed from the lower end to the upper end of the outer shell 16 in the flat configuration. The rear end portion of the handle 15 is formed in an arc shape. Preferably, the rear end of the handle 15 is formed in a semicircular shape. The handle 15 is disposed behind the shell 16.

  The upper end of the handle 15 is disposed at the same height or below the upper end of the outer shell 16. For this reason, in the flat configuration, the handle 15 does not come out above the outer shell portion 16 and the dust collection portion 17. Therefore, the height of the main body 3 of the vacuum cleaner 1 including the handle 15 can be lowered, and the low part with depth can be cleaned further to the back.

The exhaust unit 21 is disposed in a portion of the outer shell portion 16 in which the battery unit 19 is incorporated. Then, the clean air having passed through the electric blower 23 passes through the battery unit 19 and is discharged from the opening of the exhaust unit 21 to the outside of the main body 3. Therefore, the battery unit 19 can be cooled by the air flow of the clean air. Thus, the temperature rise of the battery 26 can be reduced, and the life of the battery 26 can be extended.
The other configuration is the same as that of the first embodiment, and the description thereof is omitted here.

  Even in the vacuum cleaner configured as described above, the same effects as in the first embodiment can be obtained. Furthermore, as described above, in the flat configuration, the handle 15 does not go above the outer shell 16 and the dust collector 17. Therefore, the height of the main body 3 of the vacuum cleaner 1 including the handle 15 can be lowered, and the low part with depth can be cleaned further to the back.

Third Embodiment
FIG. 33 is a side view of a main body of a vacuum cleaner according to Embodiment 3 of the present invention. Hereinafter, the vacuum cleaner according to the third embodiment will be described based on the difference from the second embodiment, taking as an example the case based on the configuration of the second embodiment.

In the electric vacuum cleaner according to Embodiment 3 of the present invention, as shown in FIG. 33, the lever portion 94 for attaching the dust collecting portion 17 to the main body 3 is disposed on the side surface of the dust collecting portion 17 instead of the upper surface Be done.
The other configuration is the same as that of the second embodiment, and the description thereof is omitted here.

  Even in the vacuum cleaner configured as described above, the same effect as that of the second embodiment can be obtained. Furthermore, since the lever portion 94 is disposed on the side surface of the dust collection portion 17 in the flat form, the height of the main body 3 of the electric vacuum cleaner 1 in the flat form can be lowered, further lowering a low place with depth. Can be cleaned up.

Fourth Embodiment
FIG. 34 is a side view of a main body of a vacuum cleaner according to Embodiment 4 of the present invention. Hereinafter, the vacuum cleaner according to the fourth embodiment will be described based on the difference from the first embodiment, taking as an example the case based on the configuration of the first embodiment. In FIG. 34, the positions of the battery unit 19 and the electric blower 23 inside the main body 3 are indicated by dotted lines. The positions of the battery unit 19 and the electric blower 23 are the same as in the first to third embodiments.

  In the electric vacuum cleaner according to Embodiment 4 of the present invention, as shown in FIG. 34, in the flat configuration, the upper front end of the handle 15 becomes thinner toward the front. The handle 15 is disposed in a range not in contact with the trajectory of the dust collection unit 17 during attachment and detachment. That is, when the dust collection portion 17 rotates in a state where the concave portion 88 of the dust collection container 87 contacts the convex portion 36 of the connection pipe portion, the dust collection portion 17 does not contact the handle 15. Further, the outer wall of the handle 15 also functions as a guide portion 401 when the dust collection portion 17 is removed. Thereby, it is easy to guide the removal direction of the dust collection part 17, and the convenience at the time of dust collection part 17 attachment or detachment can be improved.

  The upper front end portion of the handle 15 is disposed in front of the rear end portion of the dust collection portion 17. At least a part of each of the handle 15, the dust collection unit 17 and the battery unit 19 is disposed at an overlapping position in the front-rear direction. The front end of the space 402 formed between the handle 15 and the outer shell 16 is disposed at a position equivalent to the front end of the case 18 or the electric blower 23 or in front of the front end of the case 18 or the electric blower 23 Ru. The battery unit and the dust collection unit 17 partially overlap in the front-rear direction, and the front end of the handle 15 is disposed forward of the front end of the battery unit.

For this reason, particularly when lifting the front side of the vacuum cleaner 1, such as high-level cleaning, the user can hold the same or front as a heavy object, so the vacuum cleaner 1 can be lifted with a small amount of force. be able to. In addition, the guide portion 401 can be held by holding a finger. In this case, the vacuum cleaner 1 can be lifted with less force because it can hold the front further.
The other configuration is the same as that of the first embodiment, and the description thereof is omitted here.

  Even in the vacuum cleaner configured as described above, the same effects as in the first embodiment can be obtained. Furthermore, as described above, particularly when lifting the front side of the vacuum cleaner 1 upward, the vacuum cleaner 1 can be lifted with less force.
