When the connection determination unit 45 confirms that the received signal matches the main body side collation information, the control unit 46 permits the driving of the electric blower 8 and, in other cases, prohibits the driving of the electric blower 8 and the reporting unit. 47. The case where the reception signal and the main body side collation information do not coincide with each other is reported based on the confirmation result of the connection determination unit 45. Here, the term "only when the secondary battery 4 is mounted on the sweeper main body 2" is a period in which the secondary battery 4 is installed in the sweeper main body 2 for a limited period of, for example, about 10 seconds.

The switching element 42 is, for example, a field effect transistor (FET) including a gate connected to the body control device 9. The switching element 42 changes the input of the electric blower 8 in accordance with the change in the gate current.

The control power supply unit 43 converts the voltage of the power source supplied from the secondary battery 4 to the control circuit 41 into a control power supply voltage, and supplies it to the main body control device 9.

The connection determination unit 45 and the control unit 46 are executed by the body control device 9. Program. The main body control device 9 includes a microcomputer, and includes a central processing unit (not shown), a storage unit 48, an input/output (I/O) unit (not shown), and a timer (omitted) Graphic).

The memory unit 48 is, for example, an electrically erasable programmable read-only memory (EEPROM) and is a non-volatile memory.

The reporting unit 47 reports the case where the secondary battery 4 of the irregular product is connected to the scanner main body 2 in accordance with an instruction from the main body control device 9.

The secondary battery identification control executed by the body control device 9 will be described.

3 is a flow chart of secondary battery identification control of the electric appliance sweeper of the present embodiment.

As shown in FIG. 3, when the secondary battery 4 is mounted on the sweeper main body 2, the secondary battery 4 of the present embodiment is applied to the control power supply unit 43 from the secondary battery 4, and the self-control power supply is used. The unit 43 supplies power to the main body control device 9 to activate the main body control device 9 (step S1). Then, after the main body control device 9 is activated, the connection determination unit 45 of the main body control device 9 transmits an acknowledgment signal to the secondary battery 4 (step S2). The confirmation signal is any information previously stored in the memory unit 48 of the main body control device 9.

When the main body control device 9 on the side of the main body 2 of the secondary battery 4 receives the confirmation signal (step S3), it checks the confirmation signal and the battery side collation information (step S4). The battery side collation information is previously stored in the protection circuit of the secondary battery 4. When it is confirmed that the confirmation signal coincides with the battery side verification information (step S4), the secondary battery 4 sends a confirmation response signal including the information (consistency information) for confirming the coincidence confirmation to the connection determination unit 45 (step S5). . On the other hand, the secondary battery 4 confirms that the confirmation signal is inconsistent with the battery side verification information. In the case (the step S4 does not match), the confirmation response signal including the information (inconsistency information) for discriminating the inconsistency confirmation is sent back to the connection determination unit 45 (step S6).

When the connection determination unit 45 acquires the confirmation response signal from the secondary battery 4 (step S7), it checks the confirmation response signal and the main body side verification information (step S8). When it is confirmed that the confirmation response signal matches the main body side collation information (step S8 is coincident), the connection determination unit 45 determines the coincidence confirmation (step S9). On the other hand, when it is confirmed that the confirmation response signal does not coincide with the main body side collation information (step S8 does not match), the connection determination unit 45 determines the disagreement confirmation (step S10). Further, it is considered that the secondary battery 4 of the irregular product does not have the function of returning the confirmation response signal to the connection determination unit 45 regardless of the coincidence information or the inconsistency information. At this time, since the connection determination unit 45 cannot acquire the confirmation response signal, it is of course impossible to check the confirmation response signal and the main body side collation information, and it is confirmed that the confirmation response signal does not coincide with the main body side collation information (step S8 does not match), and it is determined. Inconsistent confirmation (step S10).

In addition, the confirmation response signal is a signal generated by the secondary battery 4 based on the result of the verification confirmation signal and the battery side verification information, and is different from the confirmation signal transmitted from the connection determination unit 45 to the secondary battery 4. In other words, the connection determination unit 45 stores the confirmation signals and the body verification information that are different from each other. Further, when the connection determination unit 45 collates the confirmation response signal and the body side collation information, it includes a case where the confirmation response signal is a digital signal including a plurality of bit strings, or a digital signal of a single bit. The case, or a single or multiple analog of any shape such as a sine wave, a half sine wave, an impulse, or a step. The condition of the signal.

When the connection determination unit 45 determines the coincidence confirmation, the control unit 46 permits the operation of the electric blower 8 and ends the secondary battery identification control (step S11). Then, the control unit 46 causes the electric blower 8 to operate in the operation mode selected by the operation unit 24.

On the other hand, when the connection determination unit 45 determines the inconsistency confirmation, the control unit 46 prohibits the operation of the electric blower 8 and ends the secondary battery identification control (step S12). Then, the control unit 46 blocks the supply of power to the electric blower 8 regardless of the operation mode selected by the operation unit 24, and prohibits the operation. Further, the control unit 46 reports to the user that the secondary battery 4 is an irregular product by the reporting unit 47. Further, the control unit 46 stores the case where the secondary battery 4 is an irregular product in the memory unit 48.

As described above, the electric appliance sweeper 1 of the present embodiment transmits an acknowledgment signal to the secondary battery 4 only when the secondary battery 4 is mounted on the squeegee main body 2, and collates the received signal and the collation information acquired from the secondary battery 4. In accordance with this, it is possible to significantly reduce the power consumption of the secondary battery 4 as compared with the conventional electric sweeper. That is, the electric appliance sweeper 1 of the present embodiment does not continuously transmit the confirmation signal as in the conventional electric appliance sweeper, but only when the secondary battery 4 is mounted on the sweeper main body 2, whether or not the regular product is connected is checked. The secondary battery 4, by this, greatly suppresses the consumption of electric power.

Further, the electric appliance sweeping machine 1 of the present embodiment stores mutually different confirmation signals and main body collation information, whereby both the cleaner main body 2 side and the secondary battery 4 side can mutually confirm whether or not each other is a regular product.

Further, the electric appliance sweeper 1 of the present embodiment includes a reporting unit 47 because For example, even if the secondary battery 4 of the irregular product is connected to the sweeper main body 2 without knowing the user, the electric blower 8 is not driven, and it is suspected that the electric sweeper 1 is in a malfunction, and it is possible to surely The user reports that the electric blower 8 is not driving to cause it to be properly handled.

Further, since the electric cleaning device 1 of the present embodiment includes the storage unit 48, when the secondary battery 4 connected to the irregular product is worried about the failure of the cleaning machine main body 2 side, the driving of the electric blower 8 is prohibited afterwards. When the manufacturer is inspected, or when the cause of the failure of the cleaning machine body 2 is found, the use history of the secondary battery 4 of the irregular product is confirmed, which helps to quickly ascertain the cause, etc., and the maintenance or after-sales can be improved. The convenience of the after service.

Therefore, according to the electric appliance sweeper 1 of the present invention, it is possible to confirm the power saving of whether or not the regular secondary battery 4 is mounted in the main body 2 of the sweeper.
