Abstract

A vacuum cleaner. The vacuum cleaner according to one aspect of the present invention includes: a vacuum cleaner body provided with a suction motor for generating suction, a suction part communicated with the vacuum cleaner body for sucking air and dust, and a battery capable of supplying to the vacuum cleaner body. The suction motor supplies power, the battery management device can detect the state of the battery, the charger can connect the charging current to the battery for charging the battery, and the body connector can be detachably connected for charging the battery. The charging connector of the vacuum cleaner body supplies commercial power, and the controller can control the charging of the battery; wherein, when the controller detects that the charging connector is connected to the body connector, it tries to perform The charging of the battery is retried when the charging of the battery cannot be performed normally.

Description

technical field [0001] The present invention relates to a vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner is a device that uses suction generated by a suction motor installed inside the main body to filter dust from the inside of the main body after sucking in air containing dust. [0003] Such vacuum cleaners are distinguished into manual vacuum cleaners and automatic vacuum cleaners. A manual cleaner is a cleaner that needs to be cleaned by a user himself, and an automatic cleaner is a cleaner that travels and performs cleaning by itself. [0004] The manual vacuum cleaner can be divided into: a horizontal vacuum cleaner, the suction nozzle is separately provided with the main body, and is connected through a connecting pipe; an upright vacuum cleaner, the suction nozzle is combined with the main body. [0005] Korean Laid-Open Patent Publication No. 10-2006-0118796 (published on November 24, 2006), which is a prior document, discloses a power c...
