Dust accumulation detection device and method in dust bag of vacuum cleaner

摘要

The present invention relates to an apparatus and method for detecting dust accumulation in a dust bag of a vacuum cleaner. In the related art, when a nozzle part of a vacuum cleaner is adsorbed on a cleaning surface, a pressure sensor value is different depending on the type of floor. There was a problem that the pressure sensor is larger than the floor when the carpet, flooring, curtain surface is adsorbed due to the accumulation of dust. Therefore, the present invention is based on the pressure sensor value with the nozzle in the clean state of the dust bag as a reference value, it is possible to accurately detect the accumulated state of dust in the dust bag by installing a pressure sensor that can determine the type of floor to the handle portion By doing so, you can make the cleaning more clean.
