Next, the operation of embodiment 1 will be described.
When the user grips the grip 101 of the electric vacuum cleaner 1 and operates the setting means 14, the control means 15 controls the amount of electricity flowing from the secondary battery 16 to the electric blower 12 in accordance with the operation, thereby driving the electric blower 12. The dust is directly sucked into the separator 13 from the main body suction port 100 together with air by the negative pressure generated by the driving of the electric blower 12, or the dust is sucked into the separator 13 from the main body suction port 100 through the air passage body 11 mechanically and fluidically connected to the main body suction port 100 together with air, and the dust is separated and collected in the separator 13. Further, the user operates the setting means 14 to operate the cleaning element 1112 by the magnetic element 1113 as an actuator as necessary, thereby scooping out dust entering the cleaning target portion. The air discharged from the separation portion 13 is sucked into the electric blower 12, cools the electric blower 12, and is then discharged to the outside of the cleaner main body 10. When cleaning is completed, the user operates the setting means 14, and the control means 15 stops the electric blower 12 and the like.
The electric vacuum cleaner 1 that is not used is provided with: the power plug portion is mechanically and electrically connected to the charging device 2 of the external power supply. In this case, in the present embodiment, the suction port body 111 of the electric vacuum cleaner 1 is disposed close to the disposition portion 20 of the charging device 2. In the example shown in the figure, the inlet body 111 is disposed inside the restricting portion 200 of the disposing portion 20 of the charging device 2, the bottom portion of the inlet body 111 is placed on the power feeding surface 201 of the disposing portion 20, and the power receiving surface 11102 and the power feeding surface 201 are vertically opposed to each other so as to be in contact with or close to each other. In this state, power receiving surface 11102 and power feeding surface 201 are positioned parallel or substantially parallel to each other, and power receiving unit 17 of electric vacuum cleaner 1 and power feeding unit 21 of charging device 2 are close to each other. In the present embodiment, the power receiving unit 17 and the power feeding unit 21 are disposed to face each other in the vertical direction. Preferably, a part of the power receiving portion 17 overlaps with a part of the power feeding portion 21 when viewed in the vertical direction. More preferably, power receiving unit 17 and power feeding unit 21 are positioned coaxially or substantially coaxially with each other as viewed in the vertical direction.
In charging device 2, a current is caused to flow from an external power supply to power supply unit 21 by an arbitrary triggering method, and a magnetic field is generated in power supply unit 21. Examples of the triggering method include: a method of setting or bringing the electric vacuum cleaner 1 close to the charging device 2, a method of reaching a predetermined time, a method of issuing a charging start command by a predetermined input operation or the like by the user, or a combination of these methods. Then, an induced electromotive force is generated in power receiving unit 17 of electric vacuum cleaner 1 disposed to face power feeding unit 21 and magnetically coupled to power feeding unit 21 by the magnetic field generated in power feeding unit 21, and secondary battery 16 is charged by the induced electromotive force. In the present embodiment, the power receiving unit 17 and the power feeding unit 21 are opposed to each other in the vertical direction in a state of magnetic field coupling, and the direction B of the magnetic field coupling therebetween is the vertical direction. Here, the direction B of the magnetic field means: the direction of the magnetic lines in the coil surface of the power receiving portion 17 and/or the power feeding portion 21. The magnetic field coupling between power receiving unit 17 and power feeding unit 21 is substantially distributed in the vicinity of power receiving unit 17 and power feeding unit 21, and is not affected by magnetic substance 1113 on the opposite side with respect to connection pipe 1111 in suction port body 111.
The control means 15 monitors the state of charge of the secondary battery 16 and charges the secondary battery 16 until the fully charged state, a predetermined state of charge or charge ratio, or a desired state of charge or charge ratio set by the user is reached.
According to embodiment 1, the suction port body 111 is provided with: receiving unit 17 that receives electric power for charging secondary battery 16 from power supply unit 21 that has performed magnetic field coupling, and by disposing magnetic material 1113 and receiving unit 17 on opposite sides of connecting pipe 1111, the induced electromotive force generated by power supply unit 21 in receiving unit 17 is less likely to be inhibited by magnetic material 1113, and secondary battery 16 can be efficiently charged by magnetic field coupling. Therefore, a mechanical contact portion for charging the secondary battery 16 is not required, maintenance of the contact portion is not required, and the degree of freedom in design of the main body portion 1110 of the inlet body 111 can be improved. Further, the weight of magnetic material 1113 or power receiving unit 17, or the moment about the axial center of connection pipe 1111 can reduce the shift of the center of gravity of main body 1110 of inlet body 111 to one side or the other side with respect to connection pipe 1111, and the operability in handling inlet body 111 can be improved when gripping grip 101 during cleaning.
In particular, in the case where the connection pipe 1111 is connected to the main body portion 1110 so as to be rotatable in one direction and the other direction around the axial center to form the suction port body 111, when the grip portion 101 is gripped to lift the suction port body 111 from a cleaning target portion such as a floor surface, the main body portion 1110 of the suction port body 111 can be reduced from being relatively tilted around the axial center of the connection pipe 1111 by the magnetic member 1113 or the moment of the power receiving portion 17 around the axial center of the connection pipe 1111, and the operability during cleaning can be improved.
Further, since magnetic material 1113 is an actuator, non-contact charging at power receiving unit 17 is less likely to be hindered by magnetic material 1113 even in intake body 111 including an operating unit operated by the actuator.
Further, since at least a part of power receiving unit 17 and power feeding unit 21 are located at positions facing each other in a state of being magnetically coupled, it is possible to improve the charging efficiency of secondary battery 16 and shorten the charging time.
In the present embodiment, since at least one of the power receiving unit 17 and the power feeding unit 21 is located at a position facing each other in the vertical direction in a state where the power receiving unit 17 and the power feeding unit 21 are magnetically coupled, the magnetic substance 1113 is not located within the projection range of the power receiving unit 17 and the power feeding unit 21 in the direction B of the coupled magnetic field, and the non-contact charging of the secondary battery 16 is more difficult to be hindered by the magnetic substance 1113.
In embodiment 1, the charging device 2 is not limited to a device on which the suction port body 111 of the vacuum cleaner 1 is placed.
