FIG. 7 is a control flowchart of the vacuum cleaner 50 of the present embodiment. Here, the control flowchart shown in FIG. 7 will be used for description.
When the user presses the operation start switch (step S1), the control unit 25 determines whether or not the suction port unit 1 is attached to the vacuum cleaner 50 (step S2). This determination is made by confirming whether or not one of the first reading unit 15 and the second reading unit 16 can communicate with the first radio tag 11.

When the suction port unit 1 is not installed, the control unit 25 sets the optimum various settings (suction force setting, necessity of rotation of the rotating brush, rotation speed of the rotating brush, error detection threshold value) without the suction port unit. Etc.) to automatically change and operate the vacuum cleaner 50 (step S7). For example, the vacuum cleaner 50 is operated with various settings optimal for cleaning with a brush 22 that can be used without a suction port unit. Further, various optimum settings without the suction port unit are stored in advance in the first storage unit 26. Next, the control unit 25 determines whether or not the operation end switch has been pressed (step S8). If the switch is pressed, the operation is terminated. If the switch is not pressed, the determination in step S2 is repeated.

When the suction port unit 1 is attached, the control unit 25 inputs information about the suction port unit 1 from the second storage unit 33 of the first wireless tag 11 (step S3), and based on this information, the vacuum cleaner It is determined whether or not the suction port unit 1 to which the 50 is mounted is a compatible model (step S4). Information on whether or not the vacuum cleaner 50 is a compatible model of the suction port unit 1 may be stored in the first storage unit 26 of the control unit 25, and may be stored in the second storage unit 33 of the first wireless tag 11. It may be saved. In addition, this information may be stored in both of them.
If the vacuum cleaner 50 is not a compatible model, the user is notified via a buzzer, a lamp, a display unit, or the like that the suction port unit 1 cannot be used (step S9).

When the control unit 25 determines that the vacuum cleaner 50 is a compatible model of the suction port unit 1, the control unit 25 sets various settings (suction) that are optimal for cleaning with the suction port unit 1 mounted on the vacuum cleaner 50. The vacuum cleaner 50 is operated by automatically changing the force setting, the necessity of rotating the rotating brush, the number of rotations of the rotating brush, the error detection threshold, etc.) (step S5). The various set values may be stored in the first storage unit 26 of the control unit 25, or may be stored in the second storage unit 33 of the first wireless tag 11. In addition, this information may be stored in both of them.

For example, when the floor / carpet suction port unit 1a is attached to the vacuum cleaner 50, various settings are changed so that the suction force becomes medium and the rotation speed of the rotating brush 19 increases. For example, when the futon suction port unit 1b is attached to the vacuum cleaner 50, various settings are changed so that the suction force becomes large and the rotation speed of the rotating brush 19 becomes medium. For example, when the vacuum cleaner 50 is equipped with the gap suction port unit 1c, various settings are changed so that the suction force becomes small (the setting does not have the rotating brush 19).

Next, the control unit 25 determines whether or not the operation end switch has been pressed (step S6). If the switch is pressed, the operation is terminated. If the switch is not pressed, the determination in step S2 is repeated. By repeating steps S2 to S6, it becomes possible to detect that the suction port unit 1 has been removed from the vacuum cleaner 50. For example, the control unit 25 can determine that the suction port unit 1 has been removed from the vacuum cleaner 50 when the reading unit 15 or 16 cannot communicate with the first wireless tag 11. Further, by repeating steps S2 to S6, the control unit 25 can appropriately change various settings even when the suction unit 1 is removed or replaced during operation.

The third embodiment FIG . 10A is a schematic cross-sectional view of the first connection portion 31, FIG. 10B is a schematic cross-sectional view of the second connection portion 32, and FIG. 10C is a first connection portion. It is the schematic sectional drawing of the 1st connection structure 7 which connected 31 and 2nd connection part 32.
In the first connection structure 7 shown in FIGS. 5 and 6, the surface where the first wireless tag 11 and the reading units 15 and 16 are close to each other or in contact with each other is parallel to the cross section of the air flow path 18. In the third embodiment, the surface where the first wireless tag 11 and the reading units 15 and 16 are in close proximity or in contact with each other is parallel to the air flow path 18. With such a configuration, it is possible to slim down the flow path member of the air flow path 18.
Other configurations are the same as in the first or second embodiment. In addition, the description of the first or second embodiment also applies to the third embodiment as long as there is no contradiction.
