WIPO Patent Application WO/2023/182825
Kind Code:
A1
Abstract:
The present invention relates to a vacuum cleaner in which a discharge circuit line of a power wire connected to a cleaning nozzle from a battery is integrated with a charge circuit line for charging of the battery, and thus the structure thereof is lightweight. According to an embodiment of the present invention, a discharge path and a charge path are integrated with the power wire without being structurally divided, so that the weight of the vacuum cleaner can be reduced, and both a discharge function and a charge function can be performed in a circuit line of a partial section of the power wire, and thus costs are lower than when implementing charge and discharge circuits as separate structures.
