  FIG. 7 is a flowchart illustrating an operation example of the electric vacuum cleaner according to the first embodiment.

  With reference to FIG. 7, the schematic flow of the process of the cleaner body 2 and the air cleaner 23 when the operation of the air cleaner 23 is started based on the operation state of the cleaner body 2 will be described.

  In step S101, the cleaner body control unit 24 determines whether or not the operation of the cleaner body 2 has been started. When the operation of the cleaner body 2 is not started, the process of step S101 is repeated. When the operation of the cleaner body 2 is started by the operation of the hand switch 9, step S102 is performed.

  In step S <b> 102, the cleaner main body control unit 24 generates an operation start signal as a control signal based on the start of operation of the cleaner main body 2.

  In step S <b> 103, the cleaner main body control unit 24 transmits an operation start signal from the cleaner main body communication unit 28.

  In step S104, the charging stand communication unit 33 receives an operation start signal. This information is transmitted to the charging stand control unit 29.

Moreover, the charging stand control part 29 may stop the driving | operation of the air cleaner 23 based on a control signal different from an operation start signal, for example.

  According to the first embodiment, the cleaner body control unit 24 generates a control signal based on at least one of the operation state of the cleaner body 2 and the cleaning operation. The cleaner main body communication unit 28 wirelessly transmits the control signal generated by the cleaner main body control unit 24 to the charging stand 3. The charging stand communication unit 33 receives a control signal from the cleaner body communication unit 28. The charging stand control unit 29 controls the air purifier 23 based on the control signal received by the charging stand communication unit 33. For this reason, the air cleaner 23 of the charging stand 3 can be efficiently controlled according to the use state of the cleaner body 2. Moreover, since it is not necessary to provide an electrical contact for transmitting and receiving a control signal, the air cleaner 23 can be controlled without complicating the structure of the vacuum cleaner 1.

  In Embodiment 1, the charging stand control part 29 starts the driving | operation of the air cleaner 23 based on the control signal produced | generated based on the driving | operation of the cleaner body 2 having been started, for example. In this case, the operation of the air cleaner 23 can be started simultaneously with the start of the operation of the cleaner body 2. For this reason, it is possible to efficiently collect the dust that has risen into the indoor air during cleaning. Further, in this case, power is unnecessarily consumed as compared with the case where the operation of the air purifier 23 is started immediately after the charging current detector 25 detects that the cleaner body 2 has been removed from the charging base 3. The air purifier 23 can be controlled without doing so.

  In the first embodiment, the charging stand control unit 29, for example, air based on the control signal generated based on the start of the operation of the cleaner body 2 and the detection of the cleaning operation by the cleaning operation detection sensor 26. The operation of the cleaner 23 may be started. In this case, for example, even if the cleaner main body 2 left in the room starts operating for some reason, the operation of the air cleaner 23 is not started. For this reason, the air purifier 23 can be operated in a situation where the cleaning is reliably performed.

  In the first embodiment, the cleaner main body control unit 24, for example, when the operation of the cleaner main body 2 is stopped separately from the control signal for starting the operation of the air cleaner 23. The control signal may be generated based on the elapsed time from the start to the stop of the operation. The charging stand control unit 29 is, for example, the air purifier until the time based on the control signal generated based on the elapsed time from the start to the stop of the operation of the cleaner body 2 elapses from the start of the operation of the air cleaner 23. 23 operation may be continued. In this case, a short air cleaning operation can be performed after a short cleaning, and a long air cleaning operation can be performed after a long cleaning. For this reason, the air cleaner 23 can be efficiently controlled according to the state of indoor air.

  According to Embodiment 1, the charging stand 3 includes the charging stand notification unit 31 that notifies that the air purifier 23 is in operation. For this reason, it can alert | report to a user that the air cleaner 23 is drive | operated appropriately according to the use condition of the cleaner body 2. FIG.
