Abstract

A vacuum cleaner arrangement includes a cleaner main body accommodating a secondary battery and a blower, and having a terminal connector. The arrangement also includes a charger having a charging terminal to be connected to the terminal connector for charging the cleaner main body, and the charger has a box portion accommodating a power transformer. A notice device is on the charger to indicate when the charging terminal is connected to the terminal connector such that power can be supplied from the charging terminal to the terminal connector. The charging terminal is positioned adjacent a side wall of the box portion.

Claims

1. A vacuum cleaner arrangement comprising:

a cleaner main body accommodating a secondary battery and a blower, and having a terminal connector;

a charger having a charging terminal to be connected to said terminal connector for charging said cleaner main body, and also having a box portion accommodating a power transformer; and

a notice device, on said charger, to indicate when said charging terminal is connected to said terminal connector such that power can be supplied from said charging terminal to said terminal connector,

wherein said charging terminal is positioned adjacent a side wall of said box portion.

2. The vacuum cleaner arrangement according to claim 1, wherein

said terminal connector is in said cleaner main body.

3. The vacuum cleaner arrangement according to claim 1, further comprising:

a guide for setting said cleaner main body onto said charger.

4. The vacuum cleaner arrangement according to claim 1, wherein

said notice device comprises a pilot lamp.

5. The vacuum cleaner arrangement according to claim 4, wherein

said pilot lamp is on a top of said box portion.

6. The vacuum cleaner arrangement according to claim 5, further comprising:

a handle unit for manipulating said cleaner main body, wherein a diameter of said handle unit is less than a width of said box portion.

7. The vacuum cleaner arrangement according to claim 1, wherein

said notice device is on a top of said box portion.

8. A vacuum cleaner arrangement comprising:

a cleaner main body accommodating a secondary battery and a blower, and having a terminal connector;

a suction unit for sucking dust via a suction force generated by said blower, said suction unit being positioned at a front portion of said cleaner main body;

a charger having a charging terminal to be connected to said terminal connector for charging said cleaner main body, and also having a box portion accommodating a power transformer; and

a notice device, on said charger, to indicate when said charging terminal is connected to said terminal connector such that power can be supplied from said charging terminal to said terminal connector,

wherein said charging terminal is positioned adjacent a side wall of said box portion, and said terminal connector is at a position other than where said suction unit is located.

9. The vacuum cleaner arrangement according to claim 8, further comprising:

a guide for setting said cleaner main body onto said charger.

10. The vacuum cleaner arrangement according to claim 8, wherein

said notice device comprises a pilot lamp.

11. The vacuum cleaner arrangement according to claim 10, wherein

said pilot lamp is on a top of said box portion.

12. The vacuum cleaner arrangement according to claim 11, further comprising:

a handle unit for manipulating said cleaner main body, wherein a diameter of said handle unit is less than a width of said box portion.

13. The vacuum cleaner arrangement according to claim 8, wherein

said notice device is on a top of said box portion.

14. A vacuum cleaner arrangement comprising:

a cleaner main body accommodating a secondary battery and a blower, and having a terminal connector and an engaging portion at a lower side of said cleaner main body;

a charger having a charging terminal to be connected to said terminal connector for charging said cleaner main body when said cleaner main body is mounted on said charger, and also having a box portion accommodating a power transformer;

a mounting portion for mounting part of said cleaner main body, said mounting portion extending forwardly from a front lower side of said box portion;

a mating portion to be engaged with said engaging portion, said mating portion being on said mounting portion; and

a notice device, on said charger, to indicate when said charging terminal is connected to said terminal connector such that power can be supplied from said charging terminal to said terminal connector,

wherein said charging terminal is positioned adjacent a side wall of said box portion.

15. The vacuum cleaner arrangement according to claim 14, wherein

said terminal connector is in said cleaner main body.

16. The vacuum cleaner arrangement according to claim 14, further comprising:

a guide for setting said cleaner main body onto said charger.

17. The vacuum cleaner arrangement according to claim 14, wherein

said notice device comprises a pilot lamp.

18. The vacuum cleaner arrangement according to claim 17, wherein

said pilot lamp is on a top of said box portion.

19. The vacuum cleaner arrangement according to claim 18, further comprising:

a handle unit for manipulating said cleaner main body, wherein a diameter of said handle unit is less than a width of said box portion.
