Hand (3) for controlling the driving of the cleaner, a plurality of extension pipes (4) assembled to the handle (3) to guide the suction of dust, and the suction port (5) to be fitted depending on the situation depending on the situation Consists of

상기 흡입구(5)는 통상적으로 넓은 면적을 청소하는 상용흡입구와, 청소상황에 따라서 필요시 조립하여 사용하는 보조흡입구로 구성되며, 보조흡입구는 좁은틈새등을 청소하는 틈새흡입구와, 바닥을 쓸어내면서 청소하는 빗자루흡입구로 구분된다.The inlet (5) is typically composed of a commercial inlet for cleaning a large area, and an auxiliary inlet for assembling and use if necessary according to the cleaning situation, the auxiliary inlet and the gap inlet for cleaning narrow gaps, etc., sweeping the floor It is divided into a broom suction port for cleaning.

따라서 진공청소기의 조립시 청소기본체(1)에 흡입호스(2)의 일단을 끼워서 조립하고 흡입호스(2)의 타단에 설치된 핸들(3)에는 다수개의 연장관(4)을 순서대로 끼워서 조립하며, 최하단의 연장관(4) 끝단에 흡입구(5)를 끼워 조립하여 사용한다.Accordingly, when assembling the vacuum cleaner, one end of the suction hose 2 is assembled to the cleaning main body 1, and the plurality of extension pipes 4 are sequentially assembled to the handle 3 installed at the other end of the suction hose 2. The suction inlet 5 is inserted into the lower end of the extension tube 4 and used.

그 후 사용자가 청소기를 사용하고자 할 때 전원스위치를 작동시키면, 청소기본체(1)내에 내장되어 있는 전동기가 구동되어 흡입구(5)의 흡입통로를 통해 방바닥에 있는 오물을 빨아들이게 되며, 흡입구(5)를 통해 흡입되는 오물은 연장과(4), 흡입호스(2)순을 거쳐 청소기본체(1)의 집진종이에 오물이 걸러지게 되고, 걸러진 공기는 다시 청소기본체(1)의 전동기를 냉각시키고 배기구를 통해 외부로 배기되는 것이다.Then, when the user wants to use the vacuum cleaner when operating the power switch, the electric motor built in the cleaning main body (1) is driven to suck the dirt on the floor through the suction passage of the suction port (5), suction port (5 Soil is sucked through the extension (4), the suction hose (2) in order to filter the dust on the dust collecting paper of the cleaning main body (1), the filtered air again cools the motor of the cleaning main body (1) It is exhausted to the outside through the exhaust port.

이때, 청소대상물이나 장소에 따라서 높은 곳(가구등)이나 구석진 곳(천정)을 청소하고자 하는 경우 상용흡입구를 분리시킨 뒤 보조흡입구를 조립하여 사용하도록 되어 있다.At this time, if you want to clean high places (furniture, etc.) or corners (ceilings) according to the object or place to be cleaned, the commercial intake is separated and the auxiliary intake is to be used.

즉, 상기 종래 상용흡입구의 구조는 제2도와 같이, 흡입구멍(11)을 통하여 먼지를 흡입하는 밑판(10)과, 밑판(10)의 상부에 조립되는 덮개(20)와, 밑판(10)과 덮개(20)사이에 일체로 조립되어 벽면 또는 가구(이하 벽면등이라 한다.)와의 충돌시 충격을 흡수하여 벽면 등 및 상용흡입구의 흠집 및 파손을 방지하는 고무재의 충격흡수수단(30)과, 밑판(10)과 덮개(20)의 후방 중간에 조립되어 흡입된 먼지를 청소기본체로 안내하는 연결관(40)과, 밑판(10)의 저면에 전, 후방 양측에 각각 설치되어 전, 후방으로 이동하도록 하는 롤러(50)로 구성되어 있다.That is, the structure of the conventional commercial suction port is a bottom plate 10 for sucking dust through the suction hole 11, a cover 20 assembled on the bottom plate 10, and a bottom plate 10 as shown in FIG. 2. And shock absorbing means (30) of rubber material, which are integrally assembled between the cover and the cover (20) to absorb a shock when colliding with a wall or furniture (hereinafter referred to as a wall), and to prevent scratches and breakage of the wall and the like. , The connecting pipe 40 which is assembled between the bottom plate 10 and the rear middle of the cover 20 to guide the sucked dust to the cleaning body, and is installed on both sides of the bottom and bottom of the bottom plate 10, respectively, before and after It is comprised by the roller 50 which makes it move.

It is a basic feature of the present invention that a commercial suction port electrostatic generator of a vacuum cleaner is configured as a control unit connected to a power connection pin of a connector.

상기 정전기발생부가 바닥면으로부터 설정된 간격으로 이격되면 제어부를 온/오프시켜 감전사고의 위험을 예방하도록 바닥면에 거리감지센서를 설치한 것이 본 발명의 부가적인 특징이다.An additional feature of the present invention is that a distance sensor is installed on the bottom surface of the electrostatic generator to be spaced apart from the bottom by a predetermined interval to prevent the risk of electric shock by turning on / off the control unit.

이하 본 발명의 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings of the present invention.

도면 제3도 및 제4도는 본 발명의 실시예로서, 장판이나 융단등에 깊이 박혀 있는 먼지를 강력한 정전기로 끌어내도록 흡입구멍(11)의 전방에 설치되는 정전기발생부(60)와, 정전기발생부(60)에 공급되는 전원을 제어하도록 내부에 장착되어 연결관(40)의 전원연결핀(41)에 연결되는 제어부(70)로 진공청소기의 상용흡입구 정전기발생장치를 구성한다.3 and 4 are embodiments of the present invention, an electrostatic generator 60 installed in front of the suction hole 11 so as to attract dust deeply embedded in the floor plate or the rug, etc. with strong static electricity, and the electrostatic generator The control unit 70 is mounted inside to control the power supplied to the 60 is connected to the power connection pin 41 of the connection pipe 40 constitutes a commercial suction port electrostatic generator of the vacuum cleaner.

상기 상용흡입구는 어떠한 구조를 가진 것이라도 무방하나, 본 발명이 설치되는 상용흡입구의 구조의 일실시예를 설명하면 제4도와 같이, 흡입구멍(11)을 통하여 먼지를 흡입하는 밑판(10)과, 밑판(10)의 상부에 조립되는 덮개(20)와, 밑판(10)과 덮개(20)사이에 일체로 조립되어 벽면 또는 가구와의 충돌시 충격을 흡수하여 벽면등 및 상용흡입구의 흠집 및 파손을 방지하는 고무개의 충격흡수수단(30)과, 밑판(10)과 덮개(20)의 후방 중간에 조립되어 흡입된 먼지를 청소기본체로 안내하는 연결관(40), 밑판(10)의 저면에 전, 후방 양측에 각각 설치되어 전, 후방으로 이동하도록 하는 롤러(50)로 구성한다.The commercial inlet may have any structure, but when describing the embodiment of the structure of the commercial inlet in which the present invention is installed, as shown in FIG. 4, a bottom plate 10 for sucking dust through the suction hole 11 and , The cover 20 is assembled to the top of the base plate 10, and integrally assembled between the base plate 10 and the cover 20 to absorb the impact when colliding with the wall or furniture to scratch the wall and commercial intake and Impact absorbing means 30 of the rubber dog to prevent damage, the bottom of the bottom plate 10, the connecting pipe 40, which is assembled in the middle of the rear of the bottom plate 10 and the cover 20 to guide the sucked dust to the cleaning base body The rollers 50 are provided on both the front and rear sides, and move forward and backward.

이와같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

진공청소기의 작동원리는 상술한 종래와 동일하며, 다만 본 발명을 이용하여 장판이나 용단등에 깊이 박혀 있는 먼지를 청소하고자 하는 경우 핸들에 설치된 동작버턴을 누르면 본 발명의 정전기발생부가 동작하게 된다.The operation principle of the vacuum cleaner is the same as the above-described conventional method, but when the dust is deeply embedded in the floor plate or blown out using the present invention, pressing the operation button installed on the handle will operate the electrostatic generator of the present invention.

즉, 전원은 청소기본체, 연장호스, 핸들, 연장관을 거쳐 상용흡입구의 연결관(40)에 공급하게 되며, 연결관(40)에 연결된 제어부(70)를 통하여 정전기 발생부(60)가 동작하여 강력한 정전기가 발생하게 된다.That is, the power is supplied to the connecting pipe 40 of the commercial suction port through the cleaning base, the extension hose, the handle, the extension pipe, and the static electricity generating unit 60 is operated through the control unit 70 connected to the connecting pipe 40. Strong static electricity is generated.

따라서 정전기발생부(60)는 전기이온을 가진 먼지와 반대되는 극성의 전기적 성질을 발생시키게 되며, 이러한 전기적 성질에 의하여 전기 이온화된 먼지는 그 반대 극성에 고착하게 되므로 장판이나 융단등에 깊이 박혀 있는 먼지를 빨아 들이게 된다.Therefore, the electrostatic generating unit 60 generates electrical properties of the opposite polarity to the dust having an electric ion, and the dust ionized by these electrical properties is fixed to the opposite polarity so that the dust is deeply embedded in the sheet or carpet. Will suck.

이때, 먼지는 정전기발생부(60)에 고착되므로 전기적 성질이 소멸되어야만 통상의 방법과 같이 흡입구멍(11)을 통하여 청소기본체로 흡입될 수가 있다. 따라서 제어부(70)가 정전기발생부(60)를 간헐적으로 온/오프시켜 정전기발생부(60)에 고착된 먼지가 바닥으로 다시 떨어지도록 하거나 고착력을 소멸시켜 진공청소기의 흡입력에 의하여 흡입구멍(11)을 통해 자연스럽게 흡입되도록 하면 되는 것이다.At this time, since the dust is fixed to the electrostatic generator 60, the electrical properties must be eliminated can be sucked into the cleaning basic body through the suction hole 11 as in the usual method. Therefore, the control unit 70 intermittently turns on / off the static electricity generating unit 60 so that the dust stuck to the static electricity generating unit 60 falls back to the floor or dissipates the fixing force so that the suction hole is removed by the suction force of the vacuum cleaner. 11) through the natural suction.

그러므로 이와 같은 정전기를 이용하여 깊이 박혀 있는 먼지를 빨아 들이고, 이를 다시 흡입력으로 청소하도록 하므로써, 흡입력을 종래와 같이 높일 필요없이 약간의 흡입력만으로 충분히 청소를 할 수가 있으므로 흡입력을 높이는데 따르는 흡음재의 사용과 고흡입력의 전동기등이 필요없이 저흡입력의 전동기만으로 충분하여 원가인하에도 도움을 줄 수가 있는 것이다.Therefore, by using such static electricity to suck up the deeply embedded dust and to clean it again with suction power, it is possible to clean enough with only a slight suction force without having to increase the suction power as in the prior art, so that the use of sound absorbing materials to increase the suction power and The motor of low absorption input is enough without the need of a high suction input motor, so it can help to reduce the cost.

이와 같이 정전기의 발생에 의하여 장판이나 융단등에 깊이 박혀 있는 먼지를 깨끗하게 청소를 할 수가 있어 청소효율을 향상시킬 수가 있으며, 이로인해 진공청소기의 신뢰도가 품질을 높일 수 있는 것이다.In this way, it is possible to clean the dust deeply embedded in the floor plate or the carpet by the generation of static electricity can improve the cleaning efficiency, thereby improving the quality of the vacuum cleaner reliability.

그리고, 상용흡입구를 바닥면으로부터 설정된 거리 이상으로 들어 올릴 경우 거리감지센서(80)가 이를 감지하여 제어부(70)를 오프시켜 주므로서 정전기발생부(60)의 전원을 차단시켜 부주의에 의한 감전사고의 위험을 예방할 수 있는 것이다.When the commercial suction port is lifted above the set distance from the floor surface, the distance sensor 80 detects this and turns off the control unit 70, thereby shutting off the power supply of the static electricity generating unit 60, thereby causing an accident. It can prevent the danger.

이와같이 본 발명은 상용흡입구에 정전기발생부를 설치하여 전기 이온을 가진 먼지등을 강력한 정전기로 끌어낸 뒤 청소기 고유의 흡입력으로 빨아들이도록 하므로서, 장판이나 융단등에 깊이 박혀 있는 먼지를 청소하여 청소효율을 높일 수 있는 매우 실용적인 것이다.As described above, the present invention installs an electrostatic generating unit at a commercial inlet, draws out the dust having electric ions with strong static electricity, and sucks it with a unique suction power of the cleaner, thereby cleaning the dust deeply embedded in the flooring plate or the carpet, thereby increasing the cleaning efficiency. It can be very practical.
