Cleaner-side control unit 68 that is, are disposed respectively.

  Each drive means 62-65 is a motor etc., for example, and is driven by supplying electric power from the secondary battery 2.

  The cleaner-side control means 68 controls the operation mode of the electric blower 7 by controlling the DC power control means 66 in accordance with the operation of the setting button by the operator. The cleaner-side control means 68 is configured to be able to control the driving of each of the driving means 62 to 65 corresponding to the output of the storage sensor 61.

  On the other hand, on the charging stand 3 side, a charging power source means 71 capable of supplying power to the secondary battery 2 on the vacuum cleaner 1 side and charging the secondary battery 2 is an apparatus side control means 72 and an AC power source means AC. The power supply means 73 is electrically connected to a commercial power supply. Further, the charging power source means 71, the device side control means 72, and the AC power source means 73 are electrically connected to the device side connection portion 53, respectively.

  The device-side control means 72 supplies the power of the commercial power supply via the AC power supply means 73 to the secondary battery 2 on the vacuum cleaner 1 side from the device-side connecting portion 53 by controlling the charging power supply means 71. The charging of the secondary battery 2 is configured to be controllable. The device-side control means 72 is configured to be controllable so that the electric blower 7 is operated by electric power from the AC power supply means 73 via the device-side connection portion 53.

  Next, the operation of the first embodiment will be described.

  When cleaning, the operator connects the hose body 19, extension pipe and floor brush to the main body suction port 11 in order, and grips the hand control section on the tip side of the hose body 19 to operate the predetermined setting button. To do.

  At this time, each of the valve bodies 15 and 25 and the dust collector lower lid 18 are in a closed state, and the third valve body 38 is in an open state. Therefore, the upstream side of the first dust collecting unit 6 communicates only with the main body suction port 11, and the upstream side of the electric blower chamber 8 communicates with the first dust collecting unit 6 via the communication port 21 and the opening 31. is doing.

  In this state, the cleaner-side control means 68 controls the operation of the DC power control means 66 according to the operation mode set by the operator's operation of the setting button, so that the electric blower 7 is set. Drive in the selected operation mode.

  Due to the negative pressure generated by the suction of the electric blower 7, dust is sucked together with air from the floor brush that has been run back and forth on the floor surface, and this air becomes the intake air, along with the dust, the extension pipe, the hose body 19 and It flows into the first dust collecting part 6 through the main body suction port 11.

  Of the dust sucked together with the intake air, relatively large coarse dust is accommodated in the first dust collecting unit 6 as it is, and relatively small fine dust is collected when the intake air passes through the main filter 13. It is collected by this main filter 13.

  Thereafter, the intake air passes through the communication port 21 and the opening 31 and is sucked into the electric blower 7, passes through the electric blower 7 and becomes exhaust air, and the exhaust air flows from the exhaust hole 22 to the vacuum cleaner main body. 5 is exhausted to the outside.

  And when cleaning is complete | finished, the cleaner side control means 68 stops the electric blower 7 via the DC electric power control means 66 by operator's setting operation. In this state, the operator attaches the cleaner body 5 to the attachment port 41 of the charging stand 3.

  At this time, due to the weight of the cleaner body 5, the seal packing 48 of the mounting port 41 is pressed against the lower portion of the cleaner body 5, thereby bringing the inside of the apparatus body 42 into an airtight state and the cleaner side. The connection part 36 is electrically connected to the apparatus side connection part 53 via the terminal 53a.

  At the same time, the storage sensor 61 detects the attachment of the cleaner body 5 and outputs a signal for transmitting this detection to the cleaner-side control means 68, so that the cleaner-side control means 68 is connected to the secondary battery 2. Power is supplied to each of the driving means 62 to 65, and the driving means 62 to 65 are driven to open the first valve body 15, the second valve body 25, and the dust collecting portion lower lid 18, respectively. The valve body 38 is closed.

  As a result, most of the coarse dust collected in the first dust collection unit 6 falls into the dust collection case 51 of the second dust collection unit 43 by its own weight and is collected in the dust collection case 51. .

  In this state, when charging of the secondary battery 2 is started by a predetermined operation such as connecting the charging stand 3 to the commercial power source, the secondary battery 2 is charged with the power of the commercial power source 71, the device side connection unit 53, The secondary battery 2 is supplied to the secondary battery 2 through the cleaner-side connection portion 36 and charged.

  Further, during this charging, the electric power of the commercial power source is supplied to the electric blower 7 by the apparatus-side control means 72 via the AC power supply means 73, the respective connection parts 53 and 36, and the AC power control means 67. 7 is driven, and the outside air is taken in from the upper opening 14 to the first dust collecting portion 6 through the outside air introduction hole 16 by the negative pressure generated by the driving of the electric blower 7, and this outside air is taken into the second dust collecting portion. After passing through the dust collecting case 51 of 43 and sucked into the electric blower 7 through the lower opening 24, the sub filter 26 and the opening 31, it is exhausted from the exhaust hole 22 to the outside of the cleaner body 5. .

  As a result, due to the action of this negative pressure, dust remaining in the first dust collecting portion 6, particularly dust adhering to the upstream side surface of the main filter 13 falls into the dust collecting case 51, and this dust collecting case 51 It is collected inside.

  At the same time, the deodorizing mechanism on the charging stand 3 side operates to deodorize odors generated from dust collected in the dust collecting case 51.

  The operation of the electric blower 7 continues for a predetermined time during which the dust in the first dust collecting unit 6 is sufficiently moved to the dust collecting case 51, and then the apparatus-side control means 72 supplies power to the electric blower 7 from a commercial power source. It ends by stopping.

  When the charging of the secondary battery 2 is completed, the device-side control means 72 controls the operation of the charging power supply means 71 to stop the supply of commercial power to the secondary battery 2.

  Thereafter, when the electric vacuum cleaner 1 is removed from the charging stand 3, the storage sensor 61 detects the removal and outputs a signal to the cleaner-side control means 68. The driving of 65 is controlled to close the first valve body 15, the second valve body 25, and the dust collector lower cover 18, and open the third valve body 38.

  When dust collects in the dust collecting case 51, the dust collecting case 51 is removed from the second dust collecting portion 43, and the dust is appropriately disposed in a trash box or the like.

  As described above, according to the first embodiment, when the main body 42 of the vacuum cleaner 1 is attached to the main body 42 of the charging stand 3 and the secondary battery 2 is charged by the charging power source means 71. In addition, the first dust collecting unit 6 is communicated with the second dust collecting unit 43, and the dust moving means 39 is operated to introduce outside air into the first dust collecting unit 6. Since the dust collected in the step moves to the dust collecting case 51 of the second dust collecting unit 43, the first dust collecting unit 6 of the vacuum cleaner 1 can be maintained simultaneously with the charging operation.

  As a result, it is possible to prevent the suction of the electric blower 7 from being reduced by the dust in the first dust collecting unit 6 without separately performing maintenance work for discarding the dust in the first dust collecting unit 6. The suction performance of the vacuum cleaner 1 is reduced every time it is charged, so that the opportunity for using the vacuum cleaner 1 in a state where it becomes heavier due to dust is reduced and the usability is improved. .

  Further, by using the electric blower 7 as a part of the dust moving means 39, the configuration of the entire vacuum cleaner can be simplified as compared with the case where a separate blower or the like is provided in the dust moving means 39, and this electric blower 7 operates by supplying power from a commercial power source, so that it does not consume power of the secondary battery 2 and can prevent the secondary battery 2 from being charged for a long time or a cycle life. .

  Furthermore, by providing a deodorizing mechanism that deodorizes the inside of the second dust collecting unit 43, it is possible to efficiently deodorize, and the configuration of the vacuum cleaner is complicated as in the case where such a deodorizing mechanism is provided on the vacuum cleaner side. I don't have to.

  And when moving the dust of the 1st dust collection part 6 to the dust collection case 51 of the 2nd dust collection part 43, this outside air is taken in by taking in outside air from the upper opening 14 located above the main filter 13. As a result, the dust adhering to the main filter 13 can also be moved to the dust collecting case 51, so that maintenance of the main filter 13 is not required, and the maintainability is further improved.

  In addition, by providing the sub-filter 26 in the lower opening 24, it is possible to prevent fine dust contained in the outside air from being sucked into the electric blower 7 when the dust moving means 39 operates.

  Next, a second embodiment will be described with reference to FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the second embodiment, in the first embodiment, the dust moving means 39 is operated by the negative pressure generated by the driving of the device-side electric blower 75 provided in the charging base 3. The dust collected in is moved to the dust collecting case 51 of the second dust collecting portion 43.

  That is, a lower horizontal portion 77 substantially parallel to the horizontal portion 57 is provided below the horizontal portion 57 in the electrical equipment storage chamber 45, and the first storage portion 78 and the second storage portion are provided by the lower horizontal portion 77. A portion 79 is formed in the upper and lower sections.

  In the first accommodating portion 78, the device-side electric blower 75 is accommodated with the axial direction being along the front-rear direction, and the device-side connecting portion 53 is located above the device-side electric blower 75. Yes. A device-side communication port 81 communicating with the second dust collecting portion 43 and the first housing portion 78 is formed in the vicinity of the upper side of the projecting portion 56 that defines the first housing portion 78, and the device side A sub-filter 82 that is an auxiliary filter is attached so as to cover the communication port 81. Further, device-side exhaust holes 83 communicating with the first housing portion 78 are formed in a lattice shape at the rear portion of the device body 42 that partitions the first housing portion 78. The suction side of the device-side electric blower 75 is airtightly connected to the device-side communication port 81.

  In addition, the second electrical storage unit 44 is accommodated in the second accommodating portion 79.

  Therefore, as shown in FIG. 6, inside the charging stand 3, the device side power control means 85 for controlling the power supplied from the commercial power supply to the device side electric blower 75 via the AC power supply means 73 is provided on the device side. The control means 72 is electrically connected.

  Next, the operation of the second embodiment will be described.

  When cleaning, the operator connects the hose body 19, extension pipe and floor brush to the main body suction port 11 in order, and grips the hand control section on the tip side of the hose body 19 to operate the predetermined setting button. To do.

  At this time, each valve body 15 and the dust collector lower cover 18 are in a closed state. Therefore, the upstream side of the first dust collecting unit 6 communicates only with the main body suction port 11, and the upstream side of the electric blower chamber 8 communicates with the first dust collecting unit 6 via the communication port 21 and the opening 31. is doing.

  In this state, the cleaner-side control means 68 controls the operation of the DC power control means 66 according to the operation mode set by the operator's operation of the setting button, so that the electric blower 7 is set. In the same manner as in the first embodiment, the negative pressure generated by the suction of the electric blower 7 causes the dust sucked from the floor brush that has run back and forth on the floor surface to be 1 is collected in the dust collecting unit 6.

  After the cleaning is completed, when the operator attaches the cleaner body 5 to the attachment port 41 of the charging stand 3, the seal packing 48 of the attachment port 41 is placed under the cleaner body 5 due to the weight of the cleaner body 5. Is brought into an airtight state, the cleaner-side connecting portion 36 is electrically connected to the device-side connecting portion 53 via the terminal 53a, and the storage sensor 61 is connected to the cleaner body 5. Is detected, and a signal for transmitting this detection is output to the cleaner-side control means 68, and the cleaner-side control means 68 supplies the power from the secondary battery 2 to the drive means 62, 65. Then, the driving means 62 and 65 are driven to open the first valve body 15 and the dust collector lower cover 18 respectively.

  As a result, most of the coarse dust collected in the first dust collection unit 6 falls into the dust collection case 51 of the second dust collection unit 43 by its own weight and is collected in the dust collection case 51. .

  When the secondary battery 2 is charged in the same manner as in the first embodiment, the power of the commercial power is supplied by the device-side control means 72 via the AC power supply means 73 and the device-side power control means 85 during the charging. The device-side electric blower 75 is driven to drive the device-side electric blower 75. The negative pressure generated by the drive of the device-side electric blower 75 causes the first collection from the upper opening 14 through the outside air introduction hole 16. Outside air is taken into the dust portion 6, and this outside air passes through the dust collecting case 51 of the second dust collecting portion 43 and is sucked into the device-side electric blower 75 through the sub filter 82 and the device-side communication port 81. After that, the air is exhausted from the apparatus-side exhaust hole 83 to the outside of the apparatus main body 42.

  As a result, due to the action of this negative pressure, dust remaining in the first dust collecting portion 6, particularly dust adhering to the upstream side surface of the main filter 13 falls into the dust collecting case 51, and this dust collecting case 51 It is collected inside.

  At the same time, the deodorizing mechanism on the charging stand 3 side operates to deodorize odors generated from dust collected in the dust collecting case 51.

  The operation of the apparatus-side electric blower 75 continues for a predetermined time during which the dust in the first dust collection unit 6 sufficiently moves to the dust collection case 51, and then the apparatus-side control means 72 applies commercial power to the apparatus-side electric blower 75. The process ends by stopping the power supply from the power source.

  When the charging of the secondary battery 2 is completed, the device-side control means 72 controls the operation of the charging power supply means 71 to stop the supply of commercial power to the secondary battery 2 and charge the vacuum cleaner 1. When removed from the base 3, the storage sensor 61 detects this removal and outputs a signal to the cleaner-side control means 68. The cleaner-side control means 68 controls the driving of the drive means 62 and 65, respectively. The first valve body 15 and the dust collector lower cover 18 are closed.

  As described above, according to the second embodiment, when the vacuum cleaner main body 5 of the electric vacuum cleaner 1 is attached to the apparatus main body 42 of the charging stand 3 and the secondary battery 2 is charged by the charging power source means 71. The first dust collecting unit 6 communicates with the second dust collecting unit 43, and the dust moving means 39 operates to introduce the outside air into the first dust collecting unit 6, and the first dust collecting unit 6 captures the outside air. By having the same configuration as the first embodiment, such as moving the collected dust to the dust collection case 51 of the second dust collection unit 43, the same effects as the first embodiment are obtained. Can play.

  Further, the vacuum cleaner 1 only needs to be provided with each of the first valve body 15 for taking in outside air and the dust collection unit lower cover 18 for opening and closing the first dust collection unit 6. Since the lower opening 24, the sub-filter 26, the third valve body 38, the second valve body driving means 63, the third valve body driving means 64, the AC power control means 67 and the like of the embodiment are not required, the cleaner body 5 Therefore, the vacuum cleaner body 5 can be reduced in weight, and the operability of the electric vacuum cleaner 1 during cleaning can be improved.

  In each of the above embodiments, the dust moving means 39 is automatically started and stopped while the secondary battery 2 is being charged. The dust moving means 39 is manually operated by the operator when the secondary battery 2 is charged. May be started and stopped.

  Further, the valve bodies 15, 25, 38 and the dust collector lower lid 18 may be configured to be mechanically opened and closed when the cleaner body 5 is attached to the apparatus body 42. In this case, the control by the cleaner side control means 68 is simplified.

  Furthermore, as the vacuum cleaner 1, in addition to the secondary battery 2, a so-called chargeable vacuum cleaner capable of obtaining the power of the electric blower 7 from a commercial power source using a power cord is also supported. Can be used. In this case, the electric blower 7 is to be compatible with the charging / discharging type, and the DC power control means 66 and the AC power control means 67 are provided in parallel to the electric blower 7, and the power control means 66 and 67 are selected. And the driving of the electric blower 7 can be controlled by the cleaner-side control means 68.
