PURPOSE: A filter is provided to improve the eliminating efficiency of impurities by installing an elastic unit toward a filtering container at a brush and scraping impurities from the filtering container under the contacted state of the brush and the filtering container. CONSTITUTION: A filter includes a housing, a filtering container(200), a rotary shaft, a power transferring part, and a material eliminating part. An impurity eliminating part rotates with the rotary shaft and eliminates impurities from the filtering container. The eliminated impurities are discharged through an impurity discharging pipe(140). The impurity eliminating part includes a sucking container body and a brush. The sucking container body includes a sucking container(420) and a discharge connecting pipe(430). Sucking holes(421, 423) are formed at the sucking container and sucks impurities. The discharge connecting pipe is formed at the sucking container and discharges the impurities to the impurity discharging pipe. The brush is installed at the sucking container. The cross section area of the sucking container is different according to the height of the sucking container. The discharge connecting pipe is arranged at the sucking container of a larger cross section area. |
