Abstract

본 발명은 진공청소기의 먼지봉투내 먼지누적 감지장치 및 방법에 관한 것으로, 종래에는 청소기의 노즐부분이 청소면에 흡착되어질때 바닥의 종류에 따라 압력센서값이 다르게 나오게 되는 것을 고려하지 않음에 따라 기준바닥보다 압력센서 값이 큰 카페트, 장판, 커튼면을 흡착할 경우 먼지 누적으로 오인되는 문제점이 있었다. 따라서 본 발명은 먼지 봉투가 깨끗한 상태에서 노즐을 든 상태에서의 압력센서값을 기준값으로 하고, 바닥종류를 판별할 수 있는 압력센서를 손잡이 부분에 설치하여 먼지봉투내 먼지누적상태를 정확히 감지할 수 있도록 함으로써 보다 깨끗한 청소를 할 수 있도록 한다.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.

Claims

A dust bag shear pressure sensor installed on a handle part connected to the nozzle through a pipe to determine the type of floor, a dust bag collecting dust transferred through a hose connected to the handle part, and between the dust bag and the suction motor. Dust accumulator in the dust bag of the vacuum cleaner, characterized in that consisting of a dust bag rear pressure sensor for determining how much dust is accumulated in the dust bag by installing.

Checking the pressure value of the dust bag front end pressure sensor when the power is applied, and if the value checked in the above step is less than the first set pressure value, check the pressure value of the pressure bag after the dust bag again. In the dust bag of the vacuum cleaner comprising a step of determining, and if the value checked in the above step is not more than the second set pressure value or more than the clean dust bag, the dust is accumulated in the dust bag. Dust accumulation detection method.

The method of detecting dust accumulation in a dust bag of a vacuum cleaner according to claim 2, wherein the first set value is a pressure sensor value with a nozzle held when the dust bag is clean.
