본 고안은 먼지나 오물을 강제로 흡입하여 집진커버 내부로 수거하는 진공청소기에 관한것으로 특히, 간단한 기구를 결합시켜 물청소, 광내기 등을 겸할 수 있는 다목적 진공청소기에 관한 것이다.The present invention relates to a vacuum cleaner forcibly sucking dust or dirt and collecting the dust inside the dust cover, and more particularly, to a multi-purpose vacuum cleaner that can combine water cleaning and polishing with a simple mechanism.

일반적으로 진공청소기는 고속회전하는 휀의 흡인력을 이용하여 먼지나 작은 오물 따위를 강제 흡입하는 원리로 동작하는 것으로서, 사람의 손이 잘 닿지 않는 구석구석까지의 먼지등을 힘들이지 않고 수거할 수 있으며 또한, 수거된 먼지는 일정한 장소에 버릴 수 있어서 많이 사용되고 있지만 상기와 같이 휀을 고속회전 시키기 위해 강력한 모터를 내장하고 있음에도 불구하고 종래의 진공청소기는 오직 먼지나 오물 따위만을 수거하는 단순성을 벗어나지 못했다.In general, the vacuum cleaner operates on the principle of forcibly sucking dust or small dirt by using suction force of high speed rotation, and it can collect dust to every corner that is hard to reach. In addition, the collected dust can be thrown away in a certain place, but it is used a lot, but despite the built-in powerful motor to rotate the fan at high speed as described above, the conventional vacuum cleaner did not escape the simplicity of collecting only dust or dirt.

본 고안의 목적은 이와 같은 진공청소기의 단순성을 벗어나고 내부 모터의 동력을 다른 방법으로 이용함으로써 먼지나 오물을 제거하는 본래의 기능을 함께 다른 여러가지 기능이 부가된 다목적 진공청소기를 제공하려는 것이다.The object of the present invention is to provide a multi-purpose vacuum cleaner with the addition of several other functions together with the original function of removing dust or dirt by using the power of the internal motor in a different way out of the simplicity of such a vacuum cleaner.

상기 목적을 달성하기 위하여 본 고안에서는 동력을 발생하는 모터 및 이의 동력으로 직접 구동하여 흡인력을 발생하는 휀을 내장한 몸체와, 상기 흡인력에 의해 먼지나 오물을 강제흡임 수거하는 집진커버로 결합되는 진공청소기에 있어서, 상기 휀을 구동시키는 모터축을 구동원으로 하는 감속기와, 감속기로부터 인출되어 감속구동하는 보조구동축을 구비하고 아울러 상기 보조구동축의 단부에 따른 청소기구 즉, 물청소용 브러쉬체, 광택용 솔 등을 각기 결합 사용할 수 있게 한 점에 특징이 있다.In order to achieve the above object, in the present invention, a motor having a power generating power and a body having a built-in power generating direct suction force by the power thereof, and a vacuum coupled to a dust collecting cover for forcibly collecting dust or dirt by the suction power A vacuum cleaner comprising: a speed reducer using a motor shaft for driving the fan; and a auxiliary drive shaft drawn out from the speed reducer and decelerating and driven, and a vacuum cleaner according to an end of the auxiliary drive shaft, that is, a water cleaning brush body, a polishing brush, and the like. It is characterized by the fact that each can be used in combination.

이하 본 고안의 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제 1 도와 같이, 전면에 집진커버(2)가 결합되는 몸체(1)내부에 동력을 발생하는 모터(3)와, 모터 축(4)에 직결됨과 동시에 몸체 전면의 흡기구(5)와 인접한 휀(6)이 설치되고, 또한 모터 축(4) 주변에는 후술하는 바와 같은 그 축을 구동원으로 하는 감속기(7)가 설치되어 있으며, 감속기(7)로부터 인출된 보조구동축(8)이 직하방으로 바람직하게는 몸체 저면(9)에서 수직한 중심선상을 뻗어서 그 중앙에 뚫린 구멍(9a)밖으로 약간 돌출되어 있다. 이러한 보조구동축(8)의 단부에는 다른 청소기가 즉, 예시된 바와 같은 물 청소용 브러쉬체(10)나 광택용 솔(11)등이 결합된다.As shown in FIG. 1, the motor 3 generates power in the body 1 to which the dust collecting cover 2 is coupled to the front surface, and is directly connected to the motor shaft 4 and adjacent to the inlet port 5 on the front surface of the body. (6) is provided, and a reduction gear (7) using the shaft as a drive source as described later is provided around the motor shaft (4), and the auxiliary drive shaft (8) drawn out from the reduction gear (7) is preferably directly below. Preferably it extends on the vertical center line at the bottom of the body 9 and slightly projects out of the hole 9a which is opened at the center thereof. Another cleaner is coupled to the end of the auxiliary drive shaft 8, that is, the brush 10 for cleaning water, the brush 11 for polishing, or the like, as illustrated.

한편, 상기 보조구동축(8)단부의 주위로는 상기 다른 청소기구들을 결합사용할 때 그들의 회전공간(12)을 확보하는 보호커버(13)가 상기 몸체저면(9)에 일체로 형성되고, 그 회전공간(12) 내벽에는 몸체(1) 후방에서 별도의 호오스(14)를 연결하여 상기 회전공간(12)으로 물을 주입할 수 있도록 하는 관체(15)가 설치되며, 상기 보호커버(13)의 하단 가장자리에는 상기와 같이 관체(15)를 통해 물을 주입할 때 그 물이 회전하는 청소기구에 의해 비산되는 것을 방지하는 비산방지용 브러쉬체(16)가 결합되는 구성이다.On the other hand, around the end of the auxiliary drive shaft (8) is formed integrally on the body bottom (9) with a protective cover (13) to secure their rotation space (12) when using the other cleaner mechanisms combined, the rotation The inner wall of the space 12 is provided with a tubular body 15 for injecting water into the rotating space 12 by connecting a separate hose 14 from the rear of the body 1, and of the protective cover 13. When the water is injected through the tubular body 15 as described above, the scattering prevention brush body 16 which prevents the water from being scattered by the rotating vacuum cleaner is coupled.

다음 제 2 도는 상기한 감속기(7)의 간단한 예로서 구동원으로 하는 모터축(4)의 웜(17)에 수직한 웜기어(18)가 맞물리고, 웜기어(18)와 동축을 갖는 소경기어(19)에는 보조구동축(8)에 체결된 대경기어(20)가 맞물려 된다.Next, FIG. 2 is a simple example of the above-mentioned reduction gear 7, in which a worm gear 18 perpendicular to a worm 17 of a motor shaft 4 serving as a driving source is engaged and has a small shaft 19 coaxial with the worm gear 18. ) Is engaged with the large-size gear 20 is fastened to the auxiliary drive shaft (8).

상기와 같은 본 고안 실시예의 작용을 설명하면 모터(3)가 구동됨과 동시에 직결된 휀(6)이 고속회전하고, 이 휀(6)은 그 전방의 흡기구(5)를 통해 집진 커버(2) 내부의 공기를 강제 흡입하게 되므로 집진 커버(2)내부의 압력이 떨어진다. 따라서 집진 커버(2)는 동시하지 않은 그 선단의 흡입구로 먼지나 작은 오물을 빨아들여 내부에 집진시킨다. 이와 동시에 모터축(4)의 동력이 웜(17)→웜기어(18)→소경기어(19)→대경기어(20)로 전달되는 감속기(7)에 의해 보조구동축(8)이 감속구동되는데 이의 단부는 몸체저면(9)의 구멍(9a)을 통해 보호커버(13)로 확보된 회전공간(12)으로 돌출된 것이므로 이에 다른 청소기구들을 결합시킴으로써 상기 먼지나 오물을 제거하는 작업 이외의 다른 작업도 가능하게 된다.Referring to the operation of the embodiment of the present invention as described above, while the motor (3) is driven at the same time directly connected to the fan (6) is rotated at high speed, the fan (6) is collected through the intake port (5) in front of the dust cover 2 Since the air is forcibly sucked inside, the pressure inside the dust collecting cover 2 drops. Therefore, the dust collecting cover 2 sucks dust or small dirt into the suction port of the tip which is not simultaneous and collects it inside. At the same time, the auxiliary drive shaft 8 is decelerated and driven by the reducer 7 in which the power of the motor shaft 4 is transmitted from the worm 17 to the worm gear 18 to the small diameter gear 19 to the large diameter gear 20. The end is protruded into the rotating space 12 secured by the protective cover 13 through the hole 9a of the bottom of the body 9, so that other operations other than the operation of removing the dust or dirt by combining the other vacuum cleaners It is also possible.

예컨데 물청소용 브러쉬체(10)를 결합시키고, 그 회전공간(12) 내벽에 설치된 관체(15)의 후미에는 호오스(14)를 연결하는 한편 보호커버(13)의 하단 가장자리에는 비산방지용 브러쉬체(16)를 결합시켜주면, 보조구동축(8)에 의해 물청소용 브러쉬체(10)가 회전하여 청소하려는 바닥에 마찰되어 지고 동시에 외부의 호오스(14)가 연결된 관체(15)를 통해 회전공간(12) 내부로 물을 공급하면 바닥이 물로 씻겨지게 되어 물청소가 가능한 것이다. 이때 회전하는 물청소용 브러쉬체(10)의 원심력 때문에 물이 비산되는데 그 보호커버(13)에 결합된 비산 방지용 브러쉬체(16)에 의해 밖으로 튀지는 않는다.For example, the brush body 10 for cleaning the water is coupled, and the hose 14 is connected to the rear end of the tubular body 15 installed on the inner wall of the rotary space 12, while the brush body for preventing scattering is attached to the lower edge of the protective cover 13. 16 is coupled, the rotation brush 12 through the tubular body 15 is connected to the external hose 14 is rubbed on the floor to be cleaned by rotating the brush body 10 for cleaning by the auxiliary drive shaft (8) ) If water is supplied inside, the floor is washed with water, and the water can be cleaned. At this time, water is scattered due to the centrifugal force of the rotating brush body 10 for cleaning, and does not splash out by the scattering prevention brush body 16 coupled to the protective cover 13.

또한 광내기를 할 경우에는 광택제를 바른 광택용솔(11)만을 상기 보조구동축(8)의 단부에 결합 시킴으로써 같은 동작원리로 광내기 작업을 행할 수 있는 것이다.In addition, in the case of the polishing, by combining only the polishing brush 11 with a varnish to the end of the auxiliary drive shaft (8) it is possible to perform the polishing operation by the same operation principle.

특히 상기와 같이 보조구동축(8)을 이용하여 물청소나 광내기를 할때 통상 몸체(1)를 누르면서 작업하게 되는데 그 힘을 직접적으로 받는 보조구동축(8)의 하중감은 모터축(4)에 직접 전달되지 않으므로 모터(3)가 과부하로 운전되지는 않는다.In particular, when cleaning or polishing the water using the auxiliary drive shaft 8 as described above, the work is usually carried out while pressing the body 1, and the load of the auxiliary drive shaft 8 directly receiving the force is applied to the motor shaft 4. Since it is not transmitted directly, the motor 3 does not operate with overload.

제 3 도는 상기한 모터축(4)의 동력과 감속기(7)를 통한 보조구동축(8)의 동력을 선택적으로 차단함으로써 필요이상의 동력손실을 방지하기 위해 추가기능을 갖는 감속기에 대한 다른실시예로서 감속기(7) 상부에 푸쉬록 장치(21)와, 이것에 의해 원터치 조작 가능한 2개의 푸쉬버튼(22)(22')을 설치하고, 모터축(4)의 휀(6)과 웜(17)사이를 양분시켜 한쌍의 클러치(23)를 설치하되 이 클러치(23)가 상기 일측의 푸쉬버튼(22)으로 연동되는 레버(24)로 조작되게 하는 한편, 웜(17)과 맞물리는 웜기어(18)의 수직축(25)을 상하유동 가능하게 하여 그 하부에 스프링(26)을 탄지시키고, 그 수직축(25) 상단부가 상기 타측의 푸쉬버튼(22)으로 연동되는 레버(27)와 연결시켜 된다. 이와 같은 실시예에 의하여 모터축(4)에 설치된 한쌍의 클러치(23)는 레버(24)에 의해 결합 또는 해탈되므로 이 레버(24)를 연동시키는 일측 푸쉬버튼(22)으로써 모터축(4)의 부하측 즉, 휀(6)의 동력만을 차단시킬 수 있게 되고, 이 상태에서 타측 푸쉬버튼(22')을 누르면 도시된 바와 같이 웜기어(18)가 모터축(4)의 웜(17)에서 이탈하여 구동되지 않으므로 보조구동축(9)이 차단된 결과가 되고 반대로 그 푸쉬독 장치(21)에 의해 일측 푸쉬버튼(22)이 복귀하면서 휀(6)은 다시 모터축(4)으로부터 구동될수 있는 상태가 된다.3 is another embodiment of the speed reducer having an additional function to prevent power loss more than necessary by selectively shutting off the power of the motor shaft 4 and the power of the auxiliary drive shaft 8 through the speed reducer 7. The push lock device 21 and two push buttons 22 and 22 'which are one-touch-operated by this are provided in the upper part of the reducer 7, and the worm | wing 6 and the worm 17 of the motor shaft 4 are provided. Two pairs of clutches 23 are provided to allow the clutch 23 to be operated by the lever 24 interlocked with the push button 22 on the one side, and the worm gear 18 engaged with the worm 17. The vertical axis 25 of the c) is allowed to flow up and down, and the spring 26 is held on the lower part thereof, and the upper end of the vertical axis 25 is connected to the lever 27 interlocked with the push button 22 on the other side. According to this embodiment, the pair of clutches 23 installed on the motor shaft 4 are engaged or disengaged by the lever 24, so that the motor shaft 4 is provided as one push button 22 for interlocking the lever 24. It is possible to cut off only the power of the load side, i.e., the 6, and in this state, when the other pushbutton 22 'is pressed, the worm gear 18 disengages from the worm 17 of the motor shaft 4 as shown. Since the auxiliary drive shaft 9 is blocked because it is not driven, on the contrary, the push button 22 is returned by the push-dock device 21, and the 휀 6 can be driven from the motor shaft 4 again. Becomes
