Description

업라이트청소기Upright cleaner

본 발명은 업라이트청소기에 관한 것으로, 에지테이터를 구성하는 회전브러쉬를 밀봉부재와 용이하게 조립할 수 있도록 된 업라이트청소기에 관한 것이다.The present invention relates to an upright cleaner, and more particularly, to an upright cleaner capable of easily assembling a rotating brush constituting an edge data with a sealing member.

일반적으로 업라이트청소기는 모터축에 고무벨트를 매개로 솔이 심어진 에지테이터(Agitator)를 회전시켜 바닥을 청소하는 것으로 제1도에 도시된 것과 같이, 모터축에 고무벨트를 매개로 솔이 심어진 에지테이터(Agitator)를 회전시켜 이동하면서 바닥을 청소할 수 있도록 된 흡입구체(10)와, 이 흡입구체(10)에 회동가능하게 설치됨과 더불어 구동수단(도시않됨)의 흡입력에 의해 흡입구체(10)를 통해 흡입된 먼지 등을 집진할 수 있도록 필터가 설치된 본체(20)와, 이 본체(20)의 상부에 설치되어 사용자가 밀거나 끌고 다닐 수 있도록 된 손잡이부재(30)와, 상기 본체(20)에 설치되어 구동수단의 흡입력에 의해 흡입할 수 있도록 설치됨과 더불어 상기 흡입구체(10)에 끼워서 사용할 수 있음은 물론 상기 손잡이부재(30)에 거치할 수 있도록 된 흡입호스(40)로 이루어져 있다.In general, the upright cleaner cleans the floor by rotating an agitator in which the sole is planted with a rubber belt on the motor shaft, as shown in FIG. 1, as shown in FIG. The suction inlet 10, which is capable of cleaning the floor by rotating and moving the agitator, and the suction inlet 10, which is rotatably installed, and by the suction inlet of the driving means (not shown). On the main body 20, the filter is installed to collect the dust and the like sucked, the handle member 30 is installed on the upper portion of the main body 20 so that the user can push or pull, and the main body 20 It is installed to be sucked by the suction force of the drive means and can be used to fit into the suction inlet 10, as well as made of a suction hose 40 that can be mounted on the handle member (30) There.

여기서 상기 흡입구체(10)는 제1도와 제2도에 도시된 것과 같이, 상기 본체(20)에 설치된 전원스위치에 의해 작동되도록 상하부커버(11,12)의 사이에 설치된 모터(13)와, 이 상하부커버(11,12)에 회전가능하도록 설치된 에지테이터(Agitator; 14)와, 상기 모터(13)의 회전축과 에지테이터(14)에 설치되어 모터(13)의 회전력을 전달할 수 있도록 설치된 고무벨트(15)가 설치되어 있다.Here, the suction port 10 is a motor 13 installed between the upper and lower cover (11, 12) to be operated by a power switch installed in the main body 20, as shown in FIG. Edge data (Agitator) 14 is installed on the upper and lower cover (11, 12) to be rotatable, the rotation axis of the motor 13 and the rubber is installed on the edge data 14 to be installed to transmit the rotational force of the motor (13) The belt 15 is provided.

상기 에지테이터(14)는 제2도와 제3도에 도시된 것과 같이, 상기 상하부커버(11,12)에 끼워져 고정되는 커버(14a)와, 이 커버(14a)에 끼워지는 베어링(14b)과, 상기 커버(14a)의 내측면과 밀착된 상태로 배치되는 밀봉부재(14c)와, 이 밀봉부재(14c)의 축중심으로 삽입되어 선단이 상기 베어링(14b)에 끼워지는 지지축(14d)과, 이 지지축(14d)을 수용하도록 끼워서 상기 밀봉부재(14c)의 내측에 끼워맞춰지도록 됨과 더불어 외주면에 브러쉬가 심어진 회전브러쉬(14e)와, 상기 회전브러쉬(14e)와 밀봉부재(14c)에 끼워져 체결됨과 더불어 상기 지지축(14d)이 삽입되도록 된 보울트(14f)로 이루어져 있다.As shown in FIG. 2 and FIG. 3, the edge data 14 includes a cover 14a fitted to and fixed to the upper and lower covers 11 and 12, and a bearing 14b fitted to the cover 14a. And a sealing member 14c disposed in close contact with the inner surface of the cover 14a, and a support shaft 14d inserted into the shaft center of the sealing member 14c so that the tip is fitted to the bearing 14b. And a rotary brush 14e, which is fitted to receive the support shaft 14d and fits inside the sealing member 14c, and has a brush planted on its outer circumferential surface, and the rotary brush 14e and the sealing member 14c. And a bolt 14f through which the support shaft 14d is inserted.

따라서 상기 모터(13)가 회전하게 되면 고무벨트(15)를 매개로 에지테이터(14)가 회전하게 되는 바, 이때 상기 회전브러쉬(14e)에 인가된 회전력은 보울트(14f)를 매개로 밀봉부재(14c)도 상기 베어링(14b)의 외측과 지지축(14d)에 지지되어 회전되게 된다.Therefore, when the motor 13 rotates, the edge data 14 rotates through the rubber belt 15. At this time, the rotational force applied to the rotary brush 14e is sealed through the bolt 14f. 14c is also supported by the outer side of the bearing 14b and the support shaft 14d to rotate.

이때 상기 회전브러쉬(14e)에 심어진 솔이 회전하면서 바닥의 이물질을 비산시켜 쉽게 흡입할 수 있게 된다.At this time, the brush planted in the rotary brush 14e rotates to scatter foreign substances on the floor, thereby making it easy to inhale.

그러나 에지테이터(14)를 구성하는 회전브러쉬(14e)와 밀봉부재(14c) 및 지지축(14d)에 보울트(14f)를 삽입하여 결합하기가 매우 어려워서 조립에 따르는 공수가 많이 소요됨은 물론, 작업시 조립자의 피로를 가중시키는 결점이 있었다.However, since it is very difficult to insert the bolt 14f into the rotary brush 14e, the sealing member 14c, and the support shaft 14d constituting the edge data 14, it takes a lot of labor due to assembly, as well as work. There was a flaw that aggravated the fatigue of city assemblers.

이에 본 발명은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 지지축과 간섭이 없이 회전브러쉬와 밀봉재만을 간단히 조립하도록 된 구조로, 에지테이터를구성하는 회전브러쉬를 밀봉부재와 용이하게 조립할 수 있어 조립공수가 적게 소요됨은 물론, 조립자의 피로를 덜어줄 수 있도록 된 업라이트청소기를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned drawbacks, the structure is to simply assemble the rotary brush and the sealing material without interference with the support shaft, it is possible to easily assemble the rotary brush constituting the edge data with the sealing member. Its purpose is to provide an upright cleaner, which requires less assembly labor and can reduce the fatigue of the assembler.
