Figure 9 shows the dust collection unit 14 detached from main body unit 13.

[0025] Fig. 10 is a perspective view showing the dust collection unit 14. Fig. 11 is a side view showing the dust collection unit 14. The dust collection unit 14 shown in Figs. 10 and 11 has a cylindrical shape as a whole. The dust collection unit 14 may have a prismatic shape as a whole. The dust collection unit 14 may have a prismatic shape with rounded corners as a whole.

[0026] The dust collection unit 14 includes a dust collection case 22, an inlet / outlet unit 23, a filter 24, and an attachment / detachment lever 25. The dust collection unit 14 also includes a separator (not shown) for separating dust from dust-laden air. The separator may be a cyclone-type separator that separates dust from dust-laden air by swirling the dust-laden air. The separator may be a filter-type separator. The separator may be a paper bag-type separator.

[0027] The dust collection case 22 is a case for storing dust separated from dust-laden air by the separator. The bottom surface of the dust collection case 22 forms the bottom surface of the dust collection unit 14. An outlet 22a is formed in the bottom surface of the dust collection case 22. The outlet 22a is an opening for removing dust accumulated in the dust collection unit 14, i.e., dust accumulated in the dust collection case 22. The dust collection unit 14 is provided with a lid 26 for opening and closing the outlet 22a. The lid 26 is provided on the dust collection case 22. The lid 26 is an example of an opening and closing mechanism. A valve may be provided in the dust collection unit 14 as the opening and closing mechanism.

[0028] Inlet / outlet unit 23 is provided on dust collection case 22. Inlet / outlet unit 23 is formed with suction port 23a for taking in dust-laden air into dust collection unit 14.

The upper end of the detachable lever 25 is positioned so as to protrude upward from the upper end of the inlet / outlet unit 23.

[0031] When the dust collection unit 14 is attached to the main unit 13, the upper end of the detachable lever 25 is positioned in a recess formed in the downward surface of the main case 16. When the user moves the detachable lever 25 downward against the force of the spring 27, the detachable lever 25 comes out of the recess. This allows the dust collection unit 14 to be removed from the main unit 13.

[0032] In main body 10 configured as described above, pressing the power button on operation unit 21 starts electric blower 18. For example, electric blower 18 includes fan 28. When the power button on operation unit 21 is pressed, fan 28 rotates in the forward direction. When electric blower 18 operates in the forward direction, that is, when fan 28 rotates in the forward direction, an airflow is generated in main body 10 to suck in dust.

[0033] As a result, dust-laden air enters connecting pipe 15 from suction port 15a. The dust-laden air that enters connecting pipe 15 passes through air passage 15b and enters dust collection unit 14 from connection port 15c and suction port 23a. The dust-laden air that enters dust collection unit 14 passes through air passage 23b and enters dust collection case 22, where dust is separated from the dust-laden air by a separator. The clean air from which dust has been separated enters main body case 16 from connection port 23c and connection port 16a. The clean air that enters main body case 16 passes through air passage 16b and is discharged to the outside of main body 10 from exhaust port 16c. The dust separated from the dust-laden air is collected in dust collection case 22.

[0034] [Body 11] 12 is a perspective view showing the tube body 11. The tube body 11 is a cylindrical member that is linear as a whole. The upper end of the tube body 11 is detachably connected to the connecting tube 15 of the main body 10. The tube body 11 connects the main body 10 and the suction tool 12. The tube body 11 includes a pipe 30, a pipe cover 31, a terminal 32, and a latch 33.

[0035] A linear air passage is formed inside the pipe 30, with openings at the upper and lower ends of the pipe 30. When the pipe body 11 is connected to the connecting pipe 15, the air passage communicates with air passage 15b. A pipe cover 31 is provided on the pipe 30. The pipe cover 31 covers the rear side of the pipe 30 and is arranged along the longitudinal direction of the pipe 30.

[0036] A lead wire (not shown) is arranged between the pipe 30 and the pipe cover 31. A terminal 32 is connected to one end of the lead wire. The terminal 32 is supported by the pipe 30. The terminal 32 is arranged adjacent to the upper end of the pipe 30 and along the upper end of the pipe 30. When the tube body 11 is connected to the connecting tube 15, the terminal 32 comes into contact with a metal member electrically connected to the battery unit 19. In addition, a metal member (not shown) is connected to the other end of the lead wire. The metal member is supported by the pipe 30. The metal member is arranged adjacent to the lower end of the pipe 30.

[0037] Latch 33 is provided at the upper end of pipe 30. Latch 33 is a component for maintaining the connection between tube body 11 and connecting tube 15. When the upper end of pipe 30 is inserted into connecting tube 15, a protrusion provided on the outer surface of the lower end of connecting tube 15 engages with latch 33. This maintains the connection between tube body 11 and connecting tube 15. To remove tube body 11 from connecting tube 15, the user presses the lower part of latch 33 with their finger.

[0039] The connecting pipe 42 is attached to the head 40 via the joint mechanism 41. An air passage is formed inside the connecting pipe 42, opening at the tip of the connecting pipe 42. This air passage communicates with the inside of the head 40 via the inside of the joint mechanism 41.

[0040] A lead wire (not shown) is arranged along the connecting pipe 42 and the joint mechanism 41. A terminal 43 is connected to one end of the lead wire. The terminal 43 is supported by the connecting pipe 42. The terminal 43 is arranged adjacent to the connecting pipe 42 and along the connecting pipe 42. When the suction tool 12 is connected to the tubular body 11, the terminal 43 comes into contact with a metal member connected to the lead wire of the tubular body 11. When the suction tool 12 is connected to the connecting pipe 15, the terminal 43 comes into contact with a metal member electrically connected to the battery unit 19. The other end of the lead wire is connected to an electric motor (not shown) provided in the head 40. This electrically connects the electric motor to the battery unit 19. That is, power is supplied from the battery unit 19 to the electric motor.

[0041] Latch 44 is provided on connecting pipe 42. Latch 44 is a member for maintaining the connection between suction tool 12 and tubular body 11. When connecting pipe 42 is inserted into the lower end of tubular body 11, a protrusion provided on the outer surface of the lower end of tubular body 11 engages with latch 44. This maintains the connection between suction tool 12 and tubular body 11. To remove connecting pipe 42 of suction tool 12 from tubular body 11, a user presses latch 44 with their finger. This disengages latch 44 from the protrusion on the lower end of tubular body 11. The user can remove suction tool 12 from tubular body 11 by pulling connecting pipe 42 out of the lower end of tubular body 11 while pressing latch 44.

[0042] The latch 44 has a structure similar to that of the latch 33. Therefore, the latch 44 is also used to maintain the connection between the suction tool 12 and the connection pipe 15.

[0043] In addition to the electric motor described above, the head 40 includes a case 45, a rotating brush 46, a safety switch 47, and a wheel 48. An intake port 45a is formed in the case 45. The intake port 45a is a downward opening formed in the suction tool 12 for sucking in dust. An air passage is formed in the suction tool 12, extending from the intake port 45a to the tip of the connecting pipe 42. The rotating brush 46 is provided in this air passage. The rotating brush 46 is driven by the electric motor.

[0044] The safety switch 47 is a switch for detecting that the suction tool 12 is placed on a surface to be cleaned, such as a floor.

When the suction tool 12 is placed on the floor, the wheel 48 is pressed against the floor, turning on the safety switch 47. The rotating brush 46 rotates when the safety switch 47 is turned on. When the safety switch 47 is turned off, the rotating brush 46 does not rotate.

[0045] [Support device 3] FIG. 15 is a side view showing the stand device 3. The stand device 3 has a function of supporting the vacuum cleaner 2. The stand device 3 also has a function of charging the vacuum cleaner 2. The stand device 3 also has a function of collecting dust accumulated in the vacuum cleaner 2. Although not shown, it is preferable that the stand device 3 is supplied with power from a commercial power source. The stand device 3 shown in this embodiment includes a base 50, a support stand 51, and a collection device 52.

[0046] [Base 50] The base 50 is a base portion of the support device 3. The base 50 supports the support table 51 and the collection device 52. When the vacuum cleaner 2 is supported on the support device 3, the suction tool 12 is housed in the base 50.

[0047] [Support stand 51] The support base 51 is provided on the base 50 so as to extend upward in a straight line from the base 50. The support base 51 supports the collection device 52. The support base 51 supports the main body 10 when the vacuum cleaner 2 is supported on the support device 3.

[0048] [Recovery Device 52] The collection device 52 is provided on the base 50 so as to extend upward from the base 50. The collection device 52 is a device for collecting dust accumulated in the vacuum cleaner 2. With regard to the collection device 52, a position at which the vacuum cleaner 2 is placed to collect dust accumulated in the dust collection unit 14 is set in advance. Hereinafter, this position will also be referred to as the collection position. FIG. 15 shows an example in which the dust collection unit 14 must be placed at the collection position in order to collect dust accumulated in the dust collection unit 14. The collection device 52 includes a collection unit 53, an electric blower 54, and a control unit 55.

[0049] A space S for storing collected dust is formed inside collection unit 53. Space S is larger than the internal space of dust collection case 22 of vacuum cleaner 2. FIG. 15 shows an example in which a collection position for placing dust collection unit 14 is set above collection unit 53. That is, when dust collection unit 14 is placed at the collection position above collection unit 53, collection device 52 becomes able to collect dust that has accumulated in dust collection case 22 into collection unit 53.

[0050] The collection unit 53 is formed with an inlet 53a for taking in dust. The inlet 53a is positioned so as to face the outlet 22a when the dust collection unit 14 is placed in the collection position. In the example shown in FIG. 15 , the inlet 53a is formed on the top surface of the collection unit 53. The top surface of the collection unit 53 forms the top surface of the collection device 52. The collection unit 53 is provided with a lid 56 for opening and closing the inlet 53a. The lid 56 is an example of an opening and closing mechanism. The collection unit 53 may be provided with a valve as the opening and closing mechanism. The collection unit 53 may further include a detector 57 for detecting that the dust collection unit 14 is placed in the collection position.

[0051] Electric blower 54 generates an airflow for collecting dust from dust collection unit 14 disposed at the collection position into collection unit 53. In the example shown in FIG. 15 , electric blower 54 generates a downward airflow inside collection device 52. Collection device 52 is formed with air passage 52a extending downward from inlet 53a. Air passage 52a also includes space S. Electric blower 54 is provided in air passage 52a. Clean air from which dust has been removed passes through the portion of air passage 52a where electric blower 54 is provided. In addition, exhaust port 52b is formed in a member forming the outer casing of collection device 52. Air passage 52a is a space formed inside collection device 52, extending from inlet 53a to exhaust port 52b.

[0052] Control unit 55 controls electric blower 54. Figure 15 shows an example in which control unit 55 is disposed in air passage 52a.

[0053] Fig. 16 is a diagram illustrating an example of a dust collection method. Fig. 16 shows a state in which the vacuum cleaner 2 is supported by the support device 3. In the state shown in Fig. 16, the main body unit 13 of the vacuum cleaner 2 is supported from below by the support base 51, and the dust collection unit 14 is supported from below by the collection device 52. By supporting the main body 10 of the vacuum cleaner 2 by the support base 51, the dust collection unit 14 is positioned at the collection position. Note that the main body 10 alone can also be supported by the support device 3 in a state similar to that shown in Fig. 16.

[0054] The dust collection unit 14, which is placed in the collection position, is placed on the collection unit 53 and is supported by the collection unit 53 from below. The lids 26 and 56 are not shown in FIG. 16 . The lids 26 and 56 can be opened when the dust collection unit 14 is placed in the collection position. The lids 26 and 56 may be opened and closed manually. The lids 26 and 56 may be closed unless an external force is applied, and may open when the dust collection unit 14 is placed in the collection position. The lids 26 and 56 may be closed unless an external force is applied, and may open when an airflow for collecting dust is generated in the collection unit 53. When the lids 26 and 56 are opened, the interior space of the dust collection case 22 communicates with the interior space of the collection unit 53.

[0055] 16, the dust accumulated in the dust collection unit 14 moves downward, passes through the outlet 22a and the inlet 53a, and is collected in the collection unit 53. As an example, the dust accumulated in the dust collection unit 14 falls into the collection unit 53 by its own weight.

[0056] As another example, an electric blower 54 may be used to collect dust in the collection unit 53. That is, the control unit 55 drives the electric blower 54 when the dust collection unit 14 is disposed in the collection position. As described above, the electric blower 54 generates an airflow for collecting dust from the dust collection unit 14 disposed in the collection position into the collection unit 53. The airflow generated by the electric blower 54 moves dust accumulated in the dust collection unit 14 downward and is collected in the collection unit 53. The air that enters the collection unit 53 from the dust collection unit 14 as a result of the operation of the electric blower 54 passes through the air passage 52a and is discharged from the exhaust port 52b.

[0057] As another example, the control unit 55 may control the electric blower 54 based on a detection signal from the detector 57. For example, when the detector 57 detects that the dust collection unit 14 has been placed in the collection position, the control unit 55 operates the electric blower 54 to generate an airflow for collecting dust.

[0058] As another example, the control unit 55 may control the electric blower 54 based on a detection signal from a detector provided in the main body 10 of the vacuum cleaner 2. For example, the detector detects that dust has accumulated in the dust collection unit 14 in excess of a reference amount and outputs a detection signal. The reference amount is set in advance. In this case, when the vacuum cleaner 2 is supported on the support device 3, the control unit 55 is electrically connected to the control unit 20. When the detection signal from the detector is input, the control unit 55 operates the electric blower 54 to generate an airflow for collecting dust. In this example, when the detector detects that dust has accumulated in excess of the reference amount, the dust accumulated in the dust collection unit 14 can be collected in the collection unit 53 if the dust collection unit 14 is positioned in the collection position.

[0059] In the example shown in this embodiment, dust accumulated in dust collection unit 14 of vacuum cleaner 2 can be collected in collection unit 53 of collection device 52. This allows dust collection unit 14 to be made smaller, and eliminates the need to frequently empty the dust, thereby reducing the burden on the user.

[0060] The following describes other functions and configurations that can be adopted by the vacuum cleaner system 1. If possible, the vacuum cleaner system 1 may adopt a combination of the functions and configurations described below.

[0061] Fig. 17 is a diagram showing another example of the vacuum cleaner system 1. The dust collection unit 14 can be placed in the collection position after being detached from the main unit 13. Fig. 17 shows the dust collection unit 14 placed alone on the collection unit 53.

[0062] 17, dust accumulated in dust collection unit 14 moves downward as shown by arrow B, passes through outlet 22a and inlet 53a, and is collected in collection unit 53. As an example, dust accumulated in dust collection unit 14 falls into collection unit 53 by its own weight.

[0063] An electric blower 54 may be used actively or auxiliary to collect dust. In the example shown in Fig. 17, the support base 51 is provided with a blocking body 58. The dust collection unit 14 is disposed so that the suction port 23a faces the blocking body 58. The suction port 23a is blocked by the blocking body 58. Therefore, when the electric blower 54 is started, air is taken into the dust collection unit 14 from the connection port 23c, as shown by arrow C. The air taken into the dust collection unit 14 from the connection port 23c enters the collection unit 53 from the dust collection case 22, via the discharge port 22a and the inlet port 53a.

[0064] Therefore, the airflow generated by electric blower 54 moves dust accumulated in dust collection unit 14 downward and is collected in collection unit 53. The air that enters collection unit 53 from dust collection unit 14 as a result of operation of electric blower 54 passes through air passage 52a and is discharged from exhaust port 52b.

[0065] Fig. 18 is a diagram showing another example of the vacuum cleaner system 1. The vacuum cleaner system 1 shown in Fig. 18 differs from the vacuum cleaner system 1 shown in Fig. 17 in that the support device 3 further includes a displacement prevention device 59. If the dust collection unit 14 is simply placed on the collection unit 53 by itself, there is a possibility that the dust collection unit 14 may fall off the collection unit 53. The displacement prevention device 59 is a device for preventing displacement of the dust collection unit 14 placed at the collection position.

[0066] The displacement prevention device 59 is provided on the support base 51. The displacement prevention device 59 includes a regulating body 61 that rotates around a horizontal shaft 60. The regulating body 61 is displaceable between a first position and a second position by rotating around the shaft 60. When the regulating body 61 is disposed at the first position, it prevents the dust collection unit 14 disposed at the collection position from shifting. When the regulating body 61 is disposed at the second position, it is possible to dispose the dust collection unit 14 at the collection position or to move the dust collection unit 14 disposed at the collection position. In FIG. 18 , the regulating body 61 disposed at the first position is indicated by a solid line, and the regulating body 61 disposed at the second position is indicated by a two-dot chain line.

[0067] In the example shown in FIG. 18 , the regulating body 61 disposed at the first position partially faces the dust collection unit 14 from above. A recess 61a is formed in the regulating body 61 to accommodate the tip of the detachable lever 25 when the regulating body 61 is disposed at the first position. The vertical movement of the dust collection unit 14 placed on the collection unit 53 is restricted by the regulating body 61 being disposed directly above the dust collection unit 14. Furthermore, the horizontal movement of the dust collection unit 14 is restricted by the tip of the detachable lever 25 being accommodated in the recess 61a. This prevents the dust collection unit 14 disposed at the collection position from shifting position.

[0068] 18, when the regulator 61 is disposed in the first position, a portion of the connection port 23c is blocked by the regulator 61. In order to minimize the obstruction of the flow of air taken into the dust collection unit 14 from the connection port 23c, the portion of the regulator 61 that is disposed directly above the connection port 23c when the regulator 61 is disposed in the first position may be formed in a mesh shape.

[0069] Fig. 19 is a diagram illustrating the function of displacement prevention device 59. Fig. 19 shows a state in which regulating body 61 is arranged in the second position. As shown in Fig. 19, when regulating body 61 is arranged in the second position, regulating body 61 does not interfere with vacuum cleaner 2 supported by stand device 3. Even when vacuum cleaner 2 is supported by stand device 3, dust accumulated in dust collection unit 14 can be collected in collection unit 53.

[0070] Fig. 20 is a diagram showing another example of a displacement prevention device 59. The vacuum cleaner system 1 shown in Fig. 20 differs from the vacuum cleaner system 1 shown in Fig. 18 in that the orientation of the dust collection unit 14 is reversed front to back. Restriction body 61 is formed with a recess 61b in which the tip of attachment / detachment lever 25 is accommodated when the dust collection unit 14 is placed in the first position. In the example shown in Fig. 20 as well, the tip of attachment / detachment lever 25 is accommodated in recess 61b, thereby restricting horizontal movement of dust collection unit 14.

[0071] In the example shown in Fig. 20, when electric blower 54 is started, air is drawn into dust collection unit 14 from connection port 23c and intake port 23a, as indicated by arrows C and D. The air drawn into dust collection unit 14 passes from dust collection case 22 through exhaust port 22a and intake port 53a and enters collection unit 53. Dust accumulated in dust collection unit 14 moves downward due to the airflow generated by electric blower 54 and is collected in collection unit 53. The air that has entered collection unit 53 from dust collection unit 14 as a result of operation of electric blower 54 passes through air passage 52a and is discharged from exhaust port 52b.

[0072] 20, either connection port 23c or suction port 23a may be blocked when collecting dust in collection unit 53. For example, when regulator 61 is placed in the first position, connection port 23c may be entirely blocked by regulator 61. Regulator 61 may be formed with an openable / closable opening so that the generation of airflow indicated by arrow C can be set as desired.

[0073] 21 and 22 are diagrams showing other examples of the vacuum cleaner system 1. Figs. 21 and 22 show an example in which an outlet 22a for removing dust accumulated in the dust collection case 22 is formed on the side of the dust collection case 22. The upper end of the lid 26 is supported on a horizontal shaft, and the lid 26 is attached to the dust collection case 22 so as to rotate around the shaft. Fig. 21 shows an example in which the outlet 22a is formed in a lower part of the side of the dust collection case 22. Fig. 22 shows an example in which the outlet 22a is formed across the top and bottom of the side of the dust collection case 22.

[0074] 21 and 22, dust accumulated in dust collection unit 14 moves downward as indicated by arrow B, passes through outlet 22a and inlet 53a, and is collected in collection unit 53. An electric blower 54 may be used actively or supplementarily to collect the dust. In the example shown in FIGS. 21 and 22, dust collection case 22 may be formed with an inclined surface 22b for guiding dust accumulated in dust collection case 22 to outlet 22a. Inclined surface 22b is formed so as to become lower as it approaches outlet 22a.

[0075] 21 and 22, the height of the vacuum cleaner system 1 can be reduced compared to when the outlet 22a is formed on the bottom surface of the dust collection case 22. In addition, dust is less likely to adhere to the lid 26, and dust can be collected smoothly.

[0076] 23 is a diagram showing another example of the main body 10 of the vacuum cleaner 2. In FIG. 23, the main body 10 is shown schematically for ease of explanation. In the example shown in FIG. 23, the main body unit 13 and the dust collection unit 14 are integrated together. The dust collection unit 14 may be detachable from the main body unit 13.

[0077] In the example shown in Figure 23, the entire lower part of the dust collection case 22 is opened, forming the discharge port 22a. The lid 26 is attached to the dust collection case 22 so that its end is supported by a horizontal shaft and it rotates around that shaft. The lid 26 is also provided with a lever 26a for opening and closing the lid 26. As an example, the lid 26 is constantly subjected to a force from a spring (not shown) so as to close the discharge port 22a. The lid 26 opens when the lever 26a rotates clockwise in Figure 23. When no external force is applied to the lever 26a, the lid 26 is closed.

[0078] The recovery unit 53 may have a protrusion that pushes up the lever 26a when the dust collection unit 14 is placed in the recovery position. In this case, the lid 26 opens automatically when the dust collection unit 14 is placed in the recovery position.

[0079] 24 and 25 are diagrams showing other examples of the main body 10 of the vacuum cleaner 2. The main body 10 shown in Fig. 24 differs from the main body 10 shown in Fig. 23 in that the opening and closing direction of the lid 26 is reversed front to back. The main body 10 shown in Fig. 25 differs from the main body 10 shown in Fig. 23 in that the dust collection unit 14 is provided with multiple lids 26. The opening and closing direction of the lids 26 and the number of lids 26 can be set arbitrarily.

[0080] When the dust collection unit 14 has a rectangular column shape as a whole, the lid 26 is also formed in a rectangular shape.

[0081] Fig. 26 is a diagram showing another example of the main body 10 of the vacuum cleaner 2. Figs. 23 to 25 show examples in which the dust collection unit 14 is provided with an outward-opening lid 26. As shown in Fig. 26, the dust collection unit 14 may also be provided with an inward-opening lid 26. The main body 10 shown in Fig. 26 differs from the main body 10 shown in Fig. 23 in that the lid 26 is an inward-opening lid.

[0082] 27 and 28 are diagrams showing other examples of the main body 10 of the vacuum cleaner 2. The main body 10 shown in Fig. 27 differs from the main body 10 shown in Fig. 26 in that the opening and closing direction of the lid 26 is reversed front to back. The main body 10 shown in Fig. 28 differs from the main body 10 shown in Fig. 26 in that the dust collection unit 14 is provided with multiple lids 26. Even when the dust collection unit 14 is provided with inward-opening lids 26, the opening and closing direction of the lids 26 and the number of lids 26 can be set arbitrarily.

[0083] 29 and 30 are diagrams showing another example of the main body 10 of the vacuum cleaner 2. Figs. 29 and 30 show an example in which the dust collection unit 14 of the main body 10 further includes a compression device 29. The compression device 29 is a device for compressing dust accumulated in the dust collection case 22. The dust accumulated in the dust collection case 22 is compressed by the compression device 29 and aggregates into clumps inside the dust collection case 22. This makes it easy to collect the dust into the collection unit 53.

[0084] When the dust collection unit 14 is equipped with the compression device 29, it is preferable that the lid 26 receives force from a spring or the like so that the lid 26 is not opened by the compression action of the compression device 29.

[0085] In the example shown in Fig. 29, compressor 29 has a function of mechanically compressing dust. Compressor 29 includes spiral blade members 29a and an electric motor 29b. Blade members 29a compress dust accumulated in dust collection case 22 by rotating. Blade members 29a are driven by electric motor 29b. Electric motor 29b is controlled by control unit 20. Control unit 20 may rotate blade members 29a when lid 26 is open.

[0086] In the example shown in Fig. 30, compressor 29 has a function of aerodynamically compressing dust. Compressor 29 includes a cylindrical member that opens downward. In the example shown in Fig. 30, dust is collected by this member in the center of dust collection unit 14 and forms clumps.

[0087] Fig. 31 is a diagram showing another example of the main body 10 of the vacuum cleaner 2. Fig. 31 shows the main body 10 in a schematic manner for ease of explanation. Fig. 31 shows an example in which the connecting pipe 15 is arranged in the center of the main body 10 in a plan view. In the example shown in Fig. 31, the main body unit 13 and the dust collection unit 14 are integrated. In addition, the lid 26 and the separation device are integrated.

[0088] Connecting pipe 15 is connected to dust collection case 22. For this reason, discharge port 22a is formed at an angle on dust collection case 22 so as to avoid connecting pipe 15. Lid 26 is supported at its upper end on a horizontal shaft and is provided on dust collection case 22 so as to rotate around that shaft. In the example shown in Fig. 31 as well, it is preferable that dust collection case 22 be formed with inclined surface 22b for guiding dust accumulated in dust collection case 22 to discharge port 22a.

[0089] Fig. 32 is a diagram showing another example of the vacuum cleaner system 1. Fig. 32 shows a state in which the electric vacuum cleaner 2 having the main body 10 shown in Fig. 31 is supported by the support device 3. In the example shown in Fig. 32 as well, dust that has accumulated in the dust collection unit 14 moves downward as shown by arrow B, passes through the outlet 22a and the inlet 53a, and is collected in the collection unit 53. An electric blower 54 may be used actively or auxiliary to collect the dust.

[0090] Fig. 33 is a diagram showing another example of the main body 10 of the vacuum cleaner 2. Fig. 33 shows the main body 10 in a schematic manner for ease of explanation. Fig. 33 shows an example in which the connecting pipe 15 is arranged in the central part of the main body 10 in a plan view. In the example shown in Fig. 33, the main body unit 13 and the dust collection unit 14 are integrated. Furthermore, the dust collection case 22 does not have an outlet 22a.

[0091] FIG. 34 is a diagram showing another example of the vacuum cleaner system 1. FIG. 34 shows a state in which the main body 10 shown in FIG. 33 is supported by the support device 3. The tube body 11 and suction tool 12 of the vacuum cleaner 2 are supported by the support device 3 in a state in which they are detached from the main body 10. In the example shown in FIG. 34, the main body 10 is supported by the support base 51, so that the dust collection unit 14 is positioned in the collection position. The dust collection unit 14 positioned in the collection position is placed above the collection unit 53 and is supported by the collection unit 53 from below. Furthermore, in the example shown in FIG. 34, the dust collection unit 14 is positioned in the collection position, so that the tip of the connecting pipe 15, i.e., the suction port 15a, faces the intake port 53a.

[0092] In the example shown in Fig. 34, electric blower 18 is used to collect dust in collection unit 53. As described above, when electric blower 18 rotates in the forward direction, an airflow is generated to suck dust into main body 10. Control unit 20 causes electric blower 18 to rotate in the reverse direction when dust collection unit 14 is located at the collection position, in order to send dust accumulated in dust collection unit 14 to collection unit 53. That is, control unit 20 causes fan 28 to rotate in the reverse direction.

[0093] The airflow generated by the reverse rotation of electric blower 18 causes dust accumulated in dust collection unit 14 to pass through connecting pipe 15 and be collected into collection unit 53 via suction port 15a and intake port 53a. The air that enters collection unit 53 from dust collection unit 14 by the reverse rotation of electric blower 18 passes through air passage 52a and is discharged from exhaust port 52b.

[0094] 34, electric blower 54 may be used instead of electric blower 18 to collect dust in collection unit 53, or both electric blower 18 and electric blower 54 may be used. Note that in each example shown in this embodiment, such as the example shown in FIG. 16, electric blower 18 may be used instead of electric blower 54 to collect dust in collection unit 53, or both electric blower 18 and electric blower 54 may be used.

[0095] Fig. 35 is a diagram showing another example of vacuum cleaner system 1. Vacuum cleaner system 1 shown in Fig. 35 is similar to vacuum cleaner system 1 shown in Fig. 34 in that when collecting dust in collection unit 53, dust accumulated in dust collection unit 14 is sent to connecting pipe 15. On the other hand, in vacuum cleaner system 1 shown in Fig. 35, dust accumulated in dust collection unit 14 is sent from connecting pipe 15 to pipe body 11 and collected in collection unit 53 via pipe body 11.

[0096] 35, the support device 3 includes a base 50, a holder 62, and a recovery device 52. The suction tool 12 is placed on the base 50. The base 50 also includes a sealing material 63. When the suction tool 12 is placed on the base 50, the gap between the placement surface and the suction tool 12 is sealed by the sealing material 63. In other words, the gap is closed so that air around the suction tool 12 is not sucked in through the suction port 45a.

[0097] The holder 62 is provided to extend upward from the collection device 52. The holder 62 holds the tube 11 above the collection device 52. In the example shown in FIG. 35 , the suction tool 12 is placed on the base 50, and the tube 11 is held by the holder 62, thereby supporting the vacuum cleaner 2 on the support device 3. FIG. 35 shows an example in which the tube 11 must be placed in the collection position to collect dust accumulated in the dust collection unit 14. The suction tool 12 is placed on the base 50, and the tube 11 is held by the holder 62, thereby placing the tube 11 in the collection position.

[0098] The collection device 52 is provided on the base 50. In the example shown in Fig. 35, an inlet 53a formed in the collection unit 53 faces sideways. That is, when the pipe 11 is placed at the collection position and the inlet 53a faces a specific part of the pipe 11, the collection device 52 can collect dust accumulated in the dust collection case 22 into the collection unit 53 via the pipe 11.

[0099] Figures 36 and 37 are views showing the internal structure of part E in Figure 35. As shown in Figures 36 and 37, tubular body 11 of vacuum cleaner 2 further includes air path switching valve 35. Air path switching valve 35 is a valve for switching the air path formed inside tubular body 11, i.e., inside pipe 30, between a first air path and a second air path. The first air path is an air path that runs from suction port 45a through suction tool 12, tubular body 11, and connecting pipe 15 to dust collection unit 14. Figure 36 shows an example in which the first air path is formed by air path switching valve 35.

[0100] An exhaust port 30a is formed on the side surface of the tubular body 11, that is, on the side surface of the pipe 30. In the state shown in FIG.

[0101] The second air passage is an air passage that leads from the dust collection unit 14 to the collection unit 53 via the connecting pipe 15 and a part of the tubular body 11. The second air passage is an air passage that can be formed when the tubular body 11 is arranged in the collection position. Figure 37 shows an example in which the second air passage is formed by the air passage switching valve 35.

[0102] When the duct body 11 is placed in the collection position, the duct body 11 is placed relative to the collection unit 53 so that the exhaust port 30a faces the intake port 53a. When the air-path switching valve 35 is rotated 90° clockwise from the state shown in Fig. 36, the portion of the air-path switching valve 35 that was blocking the exhaust port 30a falls over, and the space inside the duct body 11 communicates with the space inside the collection unit 53. In addition, the air path that was formed inside the pipe 30 and extended linearly from top to bottom is blocked by the air-path switching valve 35. That is, the air path switching valve 35 switches from the first air path to the second air path.

[0103] The switching of the air passage by the air passage switching valve 35 may be performed manually. The switching may be performed by the electric blower 18 operating in reverse when the pipe body 11 is located at the recovery position. The switching may be performed by the electric blower 54 generating an airflow when the pipe body 11 is located at the recovery position.

[0104] For example, when tubular body 11 is disposed in the collection position, electric blower 54 generates an airflow to form a second air passage. The airflow generated by electric blower 54 causes dust accumulated in dust collection unit 14 to pass through connecting pipe 15 and enter tubular body 11. The dust that has entered tubular body 11 is collected in collection unit 53 via exhaust port 30a and intake port 53a. The air that has entered collection unit 53 from dust collection unit 14 due to the operation of electric blower 54 passes through air passage 52a and is discharged from exhaust port 52b.

[0105] Figure 38 is a diagram showing another example of vacuum cleaner system 1. Vacuum cleaner system 1 shown in Figure 38 is similar to vacuum cleaner system 1 shown in Figure 35 in that, when collecting dust in collection unit 53, dust accumulated in dust collection unit 14 is sent to connecting pipe 15. On the other hand, in vacuum cleaner system 1 shown in Figure 38, dust accumulated in dust collection unit 14 is sent from connecting pipe 15 to suction tool 12 and collected in collection unit 53 via suction tool 12.

[0106] 38, similar to the example shown in Fig. 35, the support device 3 includes a base 50, a holder 62, and a recovery device 52. The base 50 includes a sealing material 63. When the suction tool 12 is placed on the base 50, the gap between the placement surface and the suction tool 12 is sealed by the sealing material 63.

[0107] The holder 62 is provided to extend upward from the collection device 52. The holder 62 holds the handle 17 above the collection device 52. The holder 62 also holds the main body case 16. In the example shown in FIG. 38, the suction tool 12 is placed on the base 50 and the main body unit 13 is held by the holder 62, thereby supporting the vacuum cleaner 2 on the support device 3. FIG. 38 shows an example in which the suction tool 12 must be placed in the collection position to collect dust accumulated in the dust collection unit 14. The suction tool 12 is placed on the base 50 and the main body unit 13 is held by the holder 62, thereby placing the suction tool 12 in the collection position.

[0108] Collection device 52 is provided on base 50. In the example shown in Fig. 38, an air passage extending from collection unit 53 extends to base 50. That is, inlet 53a is formed in base 50. In the example shown in Fig. 38, suction tool 12 is placed in the collection position so that inlet 45a faces inlet 53a from above, which enables collection device 52 to collect dust accumulated in dust collection case 22 into collection unit 53 via suction tool 12.

[0109] 38, in order to collect dust in collection unit 53, electric blower 18 may be operated in reverse, or electric blower 54 may be operated. For example, the airflow generated by electric blower 54 causes dust accumulated in dust collection unit 14 to pass through connecting pipe 15 and enter suction tool 12. The dust that has entered suction tool 12 is collected in collection unit 53 via suction port 45a and intake port 53a. The air that has entered collection unit 53 from dust collection unit 14 as a result of operation of electric blower 54 passes through air passage 52a and is discharged from exhaust port 52b.

[0110] 39 is a diagram showing another example of the vacuum cleaner system 1. Fig. 39 shows an example including a plurality of vacuum cleaners 2 and a support device 3. Each of the plurality of vacuum cleaners 2 is supported by the support device 3.

[0111] The support device 3 comprises a base 50, a holder 62, and a collection device 52. The suction tool 12 of the vacuum cleaner 2 is placed on the base 50. The collection device 52 is provided so as to extend upward from the base 50. The holder 62 is provided on the collection device 52. The holder 62 holds the tube body 11 of the vacuum cleaner 2. The holder 62 may also hold the main body 10 of the vacuum cleaner 2. Figure 39 shows an example in which the dust collection unit 14 must be placed in the collection position to collect dust accumulated in the dust collection unit 14. The suction tool 12 is placed on the base 50 and the tube body 11 is held by the holder 62, so that the dust collection unit 14 is placed in the collection position.

[0112] In the following, the simplest example will be described in which the vacuum cleaner system 1 includes two vacuum cleaners 2. When it is necessary to individually identify elements related to the vacuum cleaners 2, the reference numeral for the vacuum cleaner 2 located on the left side of FIG. 39 will be followed by the letter L, and the reference numeral for the vacuum cleaner 2 located on the right side will be followed by the letter R. For example, the vacuum cleaner 2L includes a main body 10L, a tube body 11L, and a suction tool 12L. The main body 10L includes a dust collection unit 14L. The dust collection unit 14L includes a dust collection case 22L. The support device 3 includes a holder 62L.

[0113] The recovery device 52 includes a recovery unit 53, an electric blower 54, and a control unit 55, as well as: It is equipped with a detector 64, a connecting pipe 65, and a valve 66.

[0114] Detector 64 detects that the vacuum cleaner 2 has been placed in the collection position. In the example shown in FIG. 39, the support device 3 supports two vacuum cleaners 2. Therefore, for the collection device 52, a first collection position for the vacuum cleaner 2L and a second collection position for the vacuum cleaner 2R are set. Detector 64L detects that the dust collection unit 14L of the vacuum cleaner 2L has been placed in the first collection position. Detector 64R detects that the dust collection unit 14R of the vacuum cleaner 2R has been placed in the second collection position.

[0115] The connecting pipe 65 connects to the dust collection unit 14, which is disposed at the collection position, from below. An air passage is formed in the connecting pipe 65, extending upward from the space S. For example, a first air passage is formed in the connecting pipe 65L, and a second air passage is formed in the connecting pipe 65R. The first air passage opens at the upper end of the connecting pipe 65L. When the dust collection unit 14L is disposed at the first collection position, the opening at the upper end of the connecting pipe 65L faces and is connected to the exhaust port 22aL formed in the dust collection case 22L. The second air passage opens at the upper end of the connecting pipe 65R. When the dust collection unit 14R is disposed at the second collection position, the opening at the upper end of the connecting pipe 65R faces and is connected to the exhaust port 22aR formed in the dust collection case 22R.

[0116] Valves 66 open and close air passages formed in connecting pipe 65. For example, valve 66L opens and closes the first air passage. Valve 66R opens and closes the second air passage. Valves 66 are controlled by control unit 55. As an example, control unit 55 controls electric blower 54 and valves 66 based on the detection result of detector 64.

[0117] In the example shown in FIG. 39 , for example, when dust collection unit 14L of vacuum cleaner 2L is placed in the first collection position, detector 64L detects that dust collection unit 14L has been placed in the first collection position. Based on the detection result of detector 64L, control unit 55 generates an airflow for collecting dust from dust collection unit 14L placed in the first collection position to collection unit 53. That is, when detector 64L detects that dust collection unit 14L has been placed in the first collection position, control unit 55 opens valve 66L and drives electric blower 54. At this time, control unit 55 keeps valve 66R closed. As a result, an airflow is generated in the first air passage from dust collection unit 14L toward collection unit 53. Due to this airflow, dust accumulated in dust collection unit 14L passes through the first flow path and is collected in collection unit 53.

[0118] Similarly, when dust collection unit 14R of vacuum cleaner 2R is placed in the second collection position, detector 64R detects that dust collection unit 14R has been placed in the second collection position. Based on the detection result of detector 64R, control unit 55 generates an airflow to collect dust from dust collection unit 14R placed in the second collection position to collection unit 53. That is, when detector 64R detects that dust collection unit 14R has been placed in the second collection position, control unit 55 opens valve 66R and drives electric blower 54. At this time, control unit 55 keeps valve 66L closed. As a result, an airflow is generated in the second air passage from dust collection unit 14R toward collection unit 53. Due to this airflow, dust accumulated in dust collection unit 14R passes through the second flow path and is collected in collection unit 53.
