[0003] [Patent Document 1] Patent No. 7165869 Summary of the Invention [Problem to be solved by the invention]

[0004] In this type of conventional vacuum cleaner set, the second electric blower is operated by connecting the vacuum cleaner to a docking station. However, when the vacuum cleaner is connected to the docking station and the second electric blower is operated, the user hears the operating noise of the second electric blower and the wind noise caused by the airflow passing through the vacuum cleaner, i.e., noise.

[0005] The present invention aims to solve the above problems and provide a vacuum cleaner set that can move dust inside the vacuum cleaner to a docking station while minimizing noise heard by people around. [Means for solving the problem]

[0006] The electric vacuum cleaner set according to claim 1 of the present invention comprises an electric vacuum cleaner having a first electric blower that generates a suction airflow, a suction nozzle that sucks in dust with the suction airflow generated by the first electric blower, a first dust collecting section that stores the dust sucked in through the suction nozzle, a dust discharge port that discharges the dust stored in the first dust collecting section to the outside, and a first control circuit that controls the operation of the first electric blower; a second electric blower that generates a suction airflow, a suction port that communicates with the dust discharge port, and a vacuum cleaner set having a first electric blower that generates a suction airflow, a suction nozzle that sucks in dust with the suction airflow generated by the first electric blower, a first dust collecting section that collects the dust sucked in through the suction nozzle, a dust discharge port that discharges the dust stored in the first dust collecting section to the outside, and a first control circuit that controls the operation of the first electric blower; In an electric vacuum cleaner set having a second dust collecting section that collects dust in the first dust collecting section that has been moved through the dust outlet and suction port, and a docking station that has a second control circuit that controls the operation of the second electric blower, a human presence sensor is provided in the electric vacuum cleaner or the docking station, and the second control circuit and / or the first control circuit operate the second electric blower on the condition that the dust outlet and suction port are connected and the human presence sensor does not detect a person.

[0007] The electric vacuum cleaner set according to claim 2 of the present invention is the electric vacuum cleaner set according to claim 1, wherein the electric vacuum cleaner or the docking station has a manual switch for operating the second electric blower.

[0008] Furthermore, the electric vacuum cleaner set according to claim 3 of the present invention is the electric vacuum cleaner set according to claim 1, wherein the electric vacuum cleaner or the docking station has a display unit that displays that the second electric blower is operating. [Effects of the Invention]

[0009] By configuring the electric vacuum cleaner set according to claim 1 of the present invention as described above, the second electric blower can be operated when no one is around the electric vacuum cleaner set, thereby preventing not only the user but also people around the user from hearing the noise caused by the second electric blower.

[0010] Furthermore, since the vacuum cleaner or docking station has a manual switch for operating the second electric blower, dust in the first dust collection section of the vacuum cleaner can be moved to the second dust collection section of the docking station even when the vacuum cleaner is used continuously.

[0011] Furthermore, since the vacuum cleaner or docking station has a display unit that indicates that the second electric blower has been activated, the user can know that the dust in the first dust collection unit of the vacuum cleaner has been moved to the second dust collection unit of the docking station while the user was away.

[Figure 3] 10 is a control flowchart. [Figure 4] FIG. 10 is a schematic explanatory view showing a vacuum cleaner set according to a second embodiment of the present invention. [Figure 5] FIG. [Figure 6] 10 is a control flowchart. DETAILED DESCRIPTION OF THE INVENTION

[0013] A first embodiment of the present invention will be described below with reference to Figures 1 to 3. Reference numeral 1 denotes a vacuum cleaner set of the present invention. This vacuum cleaner set 1 comprises a vacuum cleaner 2 and a docking station 3.

[0014] The electric vacuum cleaner 2 has a cleaner body 4, a suction nozzle 5, and a handle 6. The cleaner body 4 has a first dust collecting unit 7, a first electric blower 8, a secondary battery 9, a main circuit board 10, and power receiving terminals 11, 11. The first electric blower 8 generates a suction airflow, which sucks dust through the suction nozzle 5. The first dust collecting unit 7 collects the dust sucked through the suction nozzle 5. Furthermore, a first control circuit 12 is provided on the main circuit board 10 to control the operation of the first electric blower 8 and to control the charging of the secondary battery 9. In this embodiment, the first dust collecting unit 7 is built into the cleaner body 4, but it may be detachable from the cleaner body 4. The first dust collecting unit 7 may be a filter type or a cyclone type. The vacuum cleaner body 4 is provided with a dust discharge port 13 that communicates with the first dust collecting unit 7 and that discharges dust accumulated in the first dust collecting unit 7 to the outside. Note that the dust discharge port 13 is closed by a cover (not shown) when the vacuum cleaner is removed from the docking station 3. The suction nozzle 5 is connected to the first dust collecting unit 7 by an air intake path (not shown). Furthermore, the handle 6 is provided with an operation unit board 14, and an operation unit 15 is provided on this operation unit board 14. The first electric blower 8, secondary battery 9, power receiving terminals 11, 11, and operation unit board 14 are electrically connected to the main circuit board 10.

[0015] The docking station 3 includes a station main body 16 and a station base 17. The station main body 16 includes a second dust collecting unit 18, a second electric blower 19, a power line 21 with a power plug 20 at its end, a circuit board 22, and power supply terminals 23, 23. The second electric blower 19 generates a suction airflow. The second dust collecting unit 18 collects dust in the first dust collecting unit 7 that is moved by the suction airflow generated by the second electric blower 19. A second control circuit 24 for controlling the operation of the second electric blower 19, a manual switch 25, and an LED 26 as a display unit are provided on the circuit board 22. In this embodiment, the second dust collecting unit 18 is built into the station main body 16, but it may be detachable from the station main body 16. The dust collecting capacity of the second dust collecting unit 18 is greater than that of the first dust collecting unit 7. Furthermore, the second dust collecting unit 18 may be of a filter type or a cyclone type. The station main body 16 is provided with an inlet 27 that communicates with the second dust collecting unit 18. The station main body 16 is formed with a window 28 that is transparent to infrared rays, and a human presence sensor 29 is provided inside this window 28. The second electric blower 19, power supply terminals 23, 23, and the human presence sensor 29 are electrically connected to the circuit board 22. The human presence sensor 29 may be mounted on the circuit board 22, or may be connected to the circuit board 22 via a lead wire (not shown).

[0016] The power supply terminals 23, 23 and the power receiving terminals 11, 11 are respectively provided at positions where they are electrically connected only when the suction nozzle 5 of the vacuum cleaner 2 is placed on the station base 17 and the dust discharge port 13 is connected to the suction port 27. That is, when the second control circuit 24 detects that the power supply terminals 23, 23 and the power receiving terminals 11, 11 are electrically connected, it can be determined that the dust discharge port 13 and the suction port 27 are connected to each other. Note that the lid that closes the dust discharge port 13 may be opened mechanically by attaching the vacuum cleaner 2 to the docking station 3, or may be opened by the airflow generated by the second electric blower 19.

[0017] Next, the operation of this embodiment will be described. It is assumed that the power plug 20 of the docking station 3 is connected to an AC power source. To clean a floor or the like, a user first removes the vacuum cleaner 2 from the docking station 3. Next, the user grips the handle 6 and operates the operating unit 15. By operating the operating unit 15 in this manner, the first control circuit 12 supplies power from the secondary battery 9 to the first electric blower 8. The power supply activates the first electric blower 8 to generate a suction airflow. This suction airflow travels from the suction nozzle 5 through the first dust collecting unit 7 to the first electric blower 8, and is then discharged from the first electric blower 8 to the outside of the vacuum cleaner body 4. By moving the suction nozzle 5 along the floor while the first electric blower 8 is operating, dust on the floor can be sucked in and collected in the first dust collecting unit 7. As described above, the dust discharge port 13 is closed by a lid, so that the suction airflow is not sucked into the first dust collecting section 7 from the dust discharge port 13 .

[0018] When dust accumulates in the first dust collecting section 7 or the charge level of the secondary battery 9 decreases, the user attaches the vacuum cleaner 2 to the docking station 3. At this time, as described above, the power supply terminals 23, 23 are connected to the power receiving terminals 11, 11, and the dust discharge port 13 is communicated with the suction port 27. As a result, the first control circuit 12 supplies the power supplied via the power supply terminals 23, 23 and the power receiving terminals 11, 11 to the secondary battery 9, thereby charging the secondary battery 9.

[0019] When the power supply terminals 23, 23 and the power receiving terminals 11, 11 are electrically connected, the second control circuit 24 uses the human presence sensor 29 provided in the docking station 3 to determine whether or not a person is present around the vacuum cleaner set 1. When the human presence sensor 29 detects that a person is present around the vacuum cleaner set 1, the second control circuit 24 maintains the supply of power to the second electric blower 19. On the other hand, when the human presence sensor 29 does not detect that a person is present around the vacuum cleaner set 1, the second control circuit 24 supplies power to the second electric blower 19. When the second electric blower 19 is thus supplied with power to operate, the suction airflow generated by the second electric blower 19 moves dust stored in the first dust collecting unit 7 through the dust discharge port 13 and the suction port 27 to the second dust collecting unit 18, where it is stored. In this way, by operating the second electric blower 19 when no one is around the vacuum cleaner set 1, it is possible to prevent not only the user but also other people around the user from hearing the noise caused by the second electric blower 19. Then, when a sufficient amount of time has passed for the dust in the first dust collecting unit 7 to move to the second dust collecting unit 18, the second control circuit 24 stops the power supply to the second electric blower 19 and then turns on the LED 26. That is, when the LED 26 is turned on, it indicates that the dust in the first dust collecting unit 7 has moved to the second dust collecting unit 18. In this way, the user can know that the dust has moved from the first dust collecting unit 7 to the second dust collecting unit 18. Note that the second control circuit 24 turns off the LED 26 when it detects that the power receiving terminals 11, 11 have been separated from the power supply terminals 23, 23, i.e., when it detects that the vacuum cleaner 2 has been removed from the docking station 3.

[0020] In such an electric vacuum cleaner set 1, it is sufficient to move the dust in the first dust collecting unit 7 of the electric vacuum cleaner 2 to the second dust collecting unit 18 of the docking station 3 at any time before the next use. In particular, if the electric vacuum cleaner 2 is rechargeable, it is sufficient to move the dust in the first dust collecting unit 7 to the second dust collecting unit 18 of the docking station 3 at any time while the secondary battery 9 is being charged. Therefore, if the second electric blower 19 is operated when no one is around the electric vacuum cleaner set 1, the noise caused by the second electric blower 19 will not be heard, improving usability.

[0021] If a person remains around the electric vacuum cleaner set 1, the second electric blower 19 will not operate, and dust will not move from the first dust collecting section 7 to the second dust collecting section 18. Also, there may be cases where a user wishes to empty the first dust collecting section 7 and immediately resume cleaning. In this case, the second electric blower 19 can be manually operated by operating the manual switch 25. By manually operating the second electric blower 19 in this way, the user and people nearby will hear noise caused by the second electric blower 19, but the first dust collecting section 7 can be emptied and cleaning can be performed.

[0022] As described above, the present invention provides an electric vacuum cleaner 2 having a first electric blower 8 that generates a suction airflow, a suction nozzle 5 that sucks in dust with the suction airflow generated by the first electric blower 8, a first dust collecting section 7 that stores the dust sucked through the suction nozzle 5, a dust discharge port 13 that discharges the dust stored in the first dust collecting section 7 to the outside, and a first control circuit 12 that controls the operation of the first electric blower 8; a second electric blower 19 that generates a suction airflow, a suction port 27 that communicates with the dust discharge port 13, and a second dust collecting section 7 that stores dust in the first dust collecting section 7 that has been moved through the dust discharge port 13 and the suction port 27 by the suction airflow generated by the second electric blower 19. In an electric vacuum cleaner set (1) having a docking station (3) having a dust outlet (13) and a second control circuit (24) for controlling the operation of the second electric blower (19), the docking station (3) is provided with a human presence sensor (29), and the second control circuit (24) operates the second electric blower (19) on the condition that the dust outlet (13) and the suction port (27) are connected and the human presence sensor (29) has not detected a person. By operating the second electric blower (19) when there is no person around the electric vacuum cleaner set (1), it is possible to prevent not only the user but also people around other than the user from hearing the noise caused by the second electric blower (19).

[0023] In addition, the present invention provides a manual switch 25 for operating the second electric blower 19 in the docking station 3, so that dust in the first dust collection section 7 of the vacuum cleaner 2 can be moved to the second dust collection section 18 of the docking station 3 even when the vacuum cleaner 2 is used continuously.

[0024] Furthermore, the present invention provides the docking station 3 with an LED 26 as an indicator that indicates that the second electric blower 19 has been activated, thereby enabling the user to know that the dust in the first dust collection section 7 of the electric vacuum cleaner 2 has been moved to the second dust collection section 18 of the docking station 3 while the user was away.

[0025] Next, a second embodiment of the present invention will be described with reference to Figures 4 to 6. Reference numeral 31 denotes a vacuum cleaner set of the present invention. This vacuum cleaner set 31 comprises a vacuum cleaner 32 and a docking station 33.

[0026] The electric vacuum cleaner 32 includes a cleaner body 34, a suction nozzle 35, and a handle 36. The cleaner body 34 includes a first dust collecting unit 37, a first electric blower 38, a secondary battery 39, a main circuit board 40, and power receiving terminals 41, 41. The first electric blower 38 generates a suction airflow, which sucks dust through the suction nozzle 35. The first dust collecting unit 37 collects the dust sucked through the suction nozzle 35. A first control circuit 42 is provided on the main circuit board 40 to control the operation of the first electric blower 38 and to control charging of the secondary battery 39. In this embodiment, the first dust collecting unit 37 is built into the cleaner body 34, but it may be detachable from the cleaner body 34. The first dust collecting unit 37 may be a filter type or a cyclone type. The vacuum cleaner body 34 is provided with a dust outlet 43 that communicates with the first dust collecting unit 37 and that discharges dust accumulated in the first dust collecting unit 37 to the outside. When the vacuum cleaner is removed from the docking station 33, the dust outlet 43 is closed by a cover (not shown). The suction nozzle 35 is connected to the first dust collecting unit 37 via an air intake path (not shown). The handle 36 is further provided with an operation unit board 44, on which an operation unit 45 and an LED 56 serving as a display unit are provided. The operation unit 45 includes a manual switch 55. A window 58 that is transparent to infrared rays is formed at the tip of the handle 36, and a human presence sensor 59 is provided inside the window 58. The human presence sensor 59 may be mounted on the operation unit board 44 or may be connected to the operation unit board 44 via a lead wire (not shown). The first electric blower 38, secondary battery 39, power receiving terminals 41, 41, and operation unit board 44 are electrically connected to the main circuit board 40. That is, the human presence sensor 59 is connected to the main circuit board 40 via the operation unit board 44. Furthermore, an antenna 60 for Bluetooth (registered trademark) connection is formed on the main circuit board 40.

[0027] The docking station 33 includes a station main body 46 and a station base 47. The station main body 46 includes a second dust collecting unit 48, a second electric blower 49, a power line 51 with a power plug 50 at its end, a circuit board 52, and power supply terminals 53. The second electric blower 49 generates a suction airflow. The second dust collecting unit 48 collects dust in the first dust collecting unit 37 that is moved by the suction airflow generated by the second electric blower 49. A second control circuit 54 that controls the operation of the second electric blower 49 and an antenna 61 for Bluetooth® connection are also provided on the circuit board 52. In this embodiment, the second dust collecting unit 48 is built into the station main body 46, but it may be detachable from the station main body 46. The dust collecting capacity of the second dust collecting unit 48 is greater than that of the first dust collecting unit 37. Furthermore, the second dust collecting section 48 may be of a filter type or a cyclone type. The station main body 46 is provided with a suction port 57 that communicates with the second dust collecting section 48.

[0028] The power supply terminals 53, 53 and the power receiving terminals 41, 41 are respectively provided at positions where they are electrically connected only when the suction nozzle 35 of the vacuum cleaner 32 is placed on the station base 47 and the dust discharge port 43 is connected to the suction port 57. That is, when the first control circuit 42 detects that the power supply terminals 53, 53 and the power receiving terminals 41, 41 are electrically connected, it can be determined that the dust discharge port 43 and the suction port 57 are connected to each other. Note that the lid that closes the dust discharge port 43 may be opened mechanically by attaching the vacuum cleaner 32 to the docking station 33, or may be opened by an airflow generated by the second electric blower 49.

[0029] Next, the operation of this embodiment will be described. It is assumed that the power plug 50 of the docking station 33 is connected to an AC power source. To clean a floor or the like, a user first removes the vacuum cleaner 32 from the docking station 33. Next, the user grips the handle 36 and operates the operating unit 45. By operating the operating unit 45 in this manner, the first control circuit 42 supplies power from the secondary battery 39 to the first electric blower 38. The power supply activates the first electric blower 38 to generate a suction airflow. This suction airflow travels from the suction nozzle 35 through the first dust collecting unit 37 to the first electric blower 38, and is then discharged from the first electric blower 38 to the outside of the vacuum cleaner body 34. By moving the suction nozzle 35 along the floor while the first electric blower 38 is operating, dust on the floor can be sucked in and collected in the first dust collecting unit 37. As described above, the dust discharge port 43 is closed by the lid, so that the suction airflow is not sucked into the first dust collecting section 37 from the dust discharge port 43 .

[0030] When dust accumulates in the first dust collecting section 37 or the charge level of the secondary battery 39 decreases, the user attaches the vacuum cleaner 32 to the docking station 33. At this time, as described above, the power supply terminals 53, 53 are connected to the power receiving terminals 41, 41, and the dust discharge port 43 is connected to the suction port 57. As a result, the first control circuit 42 supplies the power supplied via the power supply terminals 53, 53 and the power receiving terminals 41, 41 to the secondary battery 39, thereby charging the secondary battery 39.

[0031] When the power supply terminals 53, 53 and the power receiving terminals 41, 41 are electrically connected, the first control circuit 42 uses the human presence sensor 59 provided at the tip of the handle 36 of the vacuum cleaner 32 to determine whether or not a person is present around the vacuum cleaner set 31. When the human presence sensor 59 detects that a person is present around the vacuum cleaner set 31, the first control circuit 42 sends a control signal via the antenna 60. When this control signal is received by the antenna 61, the second control circuit 54 maintains the supply of power to the second electric blower 49. On the other hand, when the human presence sensor 59 does not detect that a person is present around the vacuum cleaner set 31, the first control circuit 42 sends a control signal via the antenna 60. When this control signal is received by the antenna 61, the second control circuit 54 supplies power to the second electric blower 49. When power is supplied to the second electric blower 49, the second electric blower 49 generates a suction airflow that moves dust collected in the first dust collecting section 37 through the dust outlet 43 and the suction port 57 to the second dust collecting section 48, where it is collected again. By operating the second electric blower 49 when no one is around the vacuum cleaner set 31, the noise generated by the second electric blower 49 can be prevented not only from being heard by the user but also by people around the user. After a sufficient amount of time has passed for the dust in the first dust collecting section 37 to be transferred to the second dust collecting section 48, the second control circuit 54 stops supplying power to the second electric blower 49 and then sends a control signal via the antenna 61. When the antenna 60 receives this control signal, the first control circuit 42 turns on the LED 56. That is, when the LED 56 is lit, the dust in the first dust collecting section 37 has been transferred to the second dust collecting section 48. In this way, the user can know that dust has moved from the first dust collecting section 37 to the second dust collecting section 48. When the first control circuit 42 detects that the power receiving terminals 41, 41 have been separated from the power supply terminals 53, 53, that is, when the first control circuit 42 detects that the vacuum cleaner 32 has been removed from the docking station 33, it turns off the LED 56.

[0032] In such an electric vacuum cleaner set 31, it is sufficient to move the dust in the first dust collecting section 37 of the electric vacuum cleaner 32 to the second dust collecting section 48 of the docking station 33 at any time before the next use. In particular, if the electric vacuum cleaner 32 is rechargeable, it is sufficient to move the dust in the first dust collecting section 37 to the second dust collecting section 48 of the docking station 33 at any time while the secondary battery 39 is being charged. Therefore, if the second electric blower 49 is operated when no one is around the electric vacuum cleaner set 31, the noise caused by the second electric blower 49 will not be heard, improving usability.

[0033] If a person remains near the vacuum cleaner set 31, the second electric blower 49 will not operate, and dust will not move from the first dust collecting section 37 to the second dust collecting section 48. Also, there may be cases where a user wishes to empty the first dust collecting section 37 and immediately resume cleaning. In this case, the second electric blower 49 can be manually operated by operating the manual switch 55. That is, when the manual switch 55 is operated, the first control circuit 42 sends a control signal via the antenna 60. When this control signal is received by the antenna 61, the second control circuit 54 supplies power to the second electric blower 49. In this way, by manually operating the second electric blower 49, the user and people nearby will hear noise from the second electric blower 49, but the first dust collecting section 37 can be emptied and cleaning can be performed.

[0034] As described above, the present invention provides an electric vacuum cleaner 32 having a first electric blower 38 that generates a suction airflow, a suction nozzle 35 that sucks in dust by the suction airflow generated by the first electric blower 38, a first dust collecting section 37 that stores the dust sucked through the suction nozzle 35, a dust discharge port 43 that discharges the dust stored in the first dust collecting section 37 to the outside, and a first control circuit 42 that controls the operation of the first electric blower 38; a second electric blower 49 that generates a suction airflow, a suction port 57 that communicates with the dust discharge port 43, and a second dust collecting section 37 that stores dust in the first dust collecting section 37 that has been moved through the dust discharge port 43 and the suction port 57 by the suction airflow generated by the second electric blower 49. In an electric vacuum cleaner set 31 having a docking station 33 having a dust outlet 48 and a second control circuit 54 that controls the operation of the second electric blower 49, the electric vacuum cleaner 32 is provided with a human presence sensor 59, and the first control circuit 42 and the second control circuit 54 operate the second electric blower 49 on the condition that the dust outlet 43 and the suction port 57 are connected and the human presence sensor 59 has not detected a person. By operating the second electric blower 49 when there is no person around the electric vacuum cleaner set 31, it is possible to prevent not only the user but also people around other than the user from hearing the noise caused by the second electric blower 49.

[0035] In addition, the present invention provides the electric vacuum cleaner 32 with a manual switch 55 for operating the second electric blower 49, so that even when the electric vacuum cleaner 32 is used continuously, dust in the first dust collecting section 37 of the electric vacuum cleaner 32 can be moved to the second dust collecting section 48 of the docking station 33.

[0036] Furthermore, the present invention provides the electric vacuum cleaner 32 with an LED 56 as an indicator that indicates that the second electric blower 49 has been activated, thereby enabling the user to know that dust in the first dust collecting section 37 of the electric vacuum cleaner 32 has been moved to the second dust collecting section 48 of the docking station 33 while the user was away.

[0037] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the gist of the invention. For example, in the second embodiment, the human presence sensor is provided at the tip of the handle of the vacuum cleaner, but it may be provided on the vacuum cleaner body. Also, in the second embodiment, the first control circuit and the second control circuit are wirelessly connected via Bluetooth (registered trademark), but signals may be exchanged via a contact connection. Furthermore, in each of the above embodiments, only one human presence sensor is used, but multiple human presence sensors may be used. [Explanation of symbols]
