Abstract: A vacuum cleaner includes a suction port assembly, a motor generating a suction force at the suction port assembly, and a cyclone dust collecting device for centrifugally separating air drawn in through the suction port assembly and the motor in sequence. The cyclone dust-collecting device includes an air discharge port penetratingly formed on an outer circumference of the cyclone dust-collecting device and exposed to an outside of the cleaner body, for guiding the air discharged to the outside. Accordingly, since the air discharge port is disposed in the cyclone dust collecting device, not in the cleaner body, a discharge channel for connecting the cyclone dust collecting device and cleaner body is omitted and thus a structure of the vacuum cleaner becomes simplified.

The vacuum cleaner having the dust receptacle includes a cleaner body, a dust receptacle detachably mounted to the cleaner body, a UV sterilizer lamp mounted within the cleaner body to scan the dust receptacle with a UV ray, a grill protecting the UV sterilizer lamp. In the vacuum cleaner, the dust receptacle has the same structure as described above.

Abstract: A suction brush and a method for manufacturing the same are provided. The suction brush includes an opening formed toward a surface being cleaned, the UV sterilizer lamp is mounted at an inner space of the opening to project a UV ray onto the surface, and a TEFLON window member covering the inner space. The method includes mounting the UV sterilizer lamp at an inner space of an opening formed toward a surface being cleaned, connecting a TEFLON window member by fitting a plurality of connection projections formed around the opening into a plurality of connection holes formed at the TEFLON window member to correspond to the connection projections, determining a connection position for the TEFLON window member so that the inner space is ventilative, and fixing the TEFLON window member by compressing ends of the plurality of connection projections as penetrating the connection holes by heat and pressure.

Abstract: A dust-collecting apparatus for a vacuum cleaner comprises a main body including an air inlet and an air outlet, a collection unit disposed at a lower part of the main body to store therein dust and moisture separated from dust-laden air, and one or more guide units disposed in an air passage in the main body to divert the course of the air.

Abstract: A vacuum cleaner has an air path for drawn air, one or more portions of which have their surfaces nano-coated with an antibiosis and sterilization material. In an embodiment, a vacuum cleaner has a suction brush with an air inlet, a dust collecting apparatus in fluid communication with the suction brush, and a body having mounting locations for a dust collecting apparatus and a motor assembly to generate suction force. One or more portions of the air path surface of the dust collecting apparatus that contacts the air is nano-coated with an antibiosis and sterilization material.

Abstract: A dust collecting apparatus of a vacuum cleaner separately collects liquid and dust particles. In an embodiment, the dust collecting apparatus of a vacuum cleaner has a cyclone body comprising an air inlet and an air outlet, a dust collecting receptacle coupled to the lower part of the cyclone body and storing therein dust which is separated from air drawn in via the air inlet, and a liquid collecting receptacle coupled to the lower part of the dust collecting receptacle and storing therein liquid particles separated from the air and the dust which are drawn in via the air inlet.

Abstract: A dust collecting apparatus for a vacuum cleaner separates dust and liquid particles from intake air. In an embodiment, the apparatus has a cyclone body with a cylindrical part including an air inlet passage and an air outlet passage, a tapered part, and a contaminant receptacle coupled to the tapered part of the cyclone body. The tapered part has a diameter that decreases from the cylindrical part toward the contaminant receptacle. In some embodiments, a screen with holes sized to pass liquid particles is disposed inside the cyclone body, so that liquid particles and dust are separated during operation.

Abstract: A dust collecting apparatus for a vacuum cleaner, for separating dust and moisture from external air, comprises a cyclone body having an air inlet and an air outlet, a screen mounted in the cyclone body and having a plurality of moisture passing holes, and a dust receptacle engaging the cyclone body to collect therein the dust and moisture separated from the air.
