Abstract: A vacuum cleaner that includes an upright main body, an upright fan motor generating a suction force, and a wheel assembly that is mounted on the upright main body and guides movement and rotation of the upright main body. The upright main body includes a first housing that is installed on the wheel assembly so as to be rotatable in a leftward/rightward direction, and a second housing that is installed in the first housing so as to be rotatable in a forward/backward direction. The vacuum cleaner can be moved and rotated by freely moving an extension frame extending upward from the second housing in forward, backward, leftward, and rightward directions.

Abstract: The present invention relates to a door lock structure including: an inner fixing plate having a protruding ring adapted to rotatably receive one end of the inner lever; an inner mounting plate adapted to abut against one surface of the inner fixing plate; an outer fixing plate having a center hole adapted to rotatably receive one end of the outer lever and a plurality of protruding portions extending circumferentially from the center hole; an outer mounting plate adapted to abut against one side of the outer fixing plate and having a plurality of through-holes formed along the circumferential direction thereof; and elastic means adapted to provide a given elastic force so as to allow the inner lever and the outer lever to be returned to their original positions.

Abstract: A filter assembly comprises a filter body for filtering dust and a filter housing for supporting the filter body. The filter body is configured in the form of a corrugation having alternate ridges and grooves, wherein a gap in the groove is blocked or shaped so as to prevent adhesion of the dust therein. Accordingly, detachment of the dust becomes easy when cleaning the filter body, and therefore, the filter assembly can maintain its performance as good as new one after being cleaned. A vacuum cleaner utilizing the filter assembly also provides the benefits of easy removal of the dust.
