Title:
VACUUM CLEANER
Document Type and Number:
WIPO Patent Application WO/2017/077577
Kind Code:
A1
Abstract:
Provided is a vacuum cleaner, wherein a secondary battery (204) in a cleaner main body (200) is charged during storage, and when in use, power from the secondary battery (204) causes an electric blower (212) for sucking dust to rotate. When a power failure is detected, an illumination unit (250) is turned on with power from the secondary battery (204). When the cleaner main body (200) is connected to an external power source (420) and no power is supplied to the cleaner main body (200) from the external power source (420), it is determined that a power failure of the external power source (420) has occurred. The illumination unit is automatically turned on when a power failure occurs, thereby allowing a user to immediately understand the situation. Additionally, the presence of the illumination unit in the vacuum cleaner eliminates the need of another plug or another secondary battery.
