본 고안은 흡입 유로의 관내에서 생기는 흡입손실과 소음을 줄이면서, 광감지 소자덮게부에 접착되어 기능을 저하시키는 먼지등 오물을 제거하기 쉽도록 하여주는 진공청소기의 오물 흡입량 검지구에 관한 것이다.The present invention relates to a dust suction detection detector of a vacuum cleaner, which reduces the suction loss and noise generated in the tube of the suction passage, and makes it easy to remove dirt such as dust, which is adhered to the light sensing element cover and degrades its function.
종래 진공 청소기는 흡입구에서 흡입된 오물이 연장관을 거쳐 손잡이관을 통하여 본체에 집적되는데, 상기 손잡이관에 장착된 발광소자와 수광소자 및 검지부로 구성된 광감지가 관내를 통과하는 오물의 흡입량을 검지하여 흡입력을 조절하도록 되어 있고, 상기 흡입된 오물이 상기 소자덮개부에 부착되어 검지기능을 떨어뜨리지 않도록 하기 위해 관내의 직경차이를 두되, 제1도에 도시되는 바와같이 소자덮개부위의 내경이 작아지는 경사부를 두어 소자덮개부위를 유속이 빠르게 통과함을 인해, 상기 소자덮개부를 오물이 접착되는 것을 방지하도록 되어 있다. 그러나, 이러한 종래의 진공 청소기는, 관내 경사부를 지나는 오물 및 유체의 와류로 인해, 소음과 흡입손실이 발생되는 단점을 가지고 있다.In the conventional vacuum cleaner, the dirt sucked from the suction port is integrated in the main body through the handle tube through an extension tube. The suction force is adjusted, and the diameter difference in the tube is set so that the sucked dirt is attached to the element cover part so as not to degrade the detection function. As shown in FIG. 1, the inner diameter of the element cover part is reduced. Since the flow velocity passes quickly through the element cover portion by placing the inclined portion, the element cover portion is prevented from adhering to the dirt. However, such a conventional vacuum cleaner has a disadvantage in that noise and suction loss are generated due to vortices of dirt and fluid passing through the inclined portion of the tube.
본 고안의 목적은 흡입된 오물을 본체로 유도하는 과정에서 발생하는 소음과 흡입손실을 줄이고, 뿐만아니라 광감지부의 소자덮개에 접착된 오물을 용이하게 씻어주는 시일링을 장착한 청소기의 오물 흡입량 검지구를 제공하기 위한 것이다.The purpose of the present invention is to reduce the noise and suction loss generated in the process of inducing the sucked dirt to the main body, as well as to detect the dirt suction amount of the vacuum cleaner equipped with a seal ring to easily wash the dirt adhered to the element cover of the light sensing unit. It is to provide the earth.
이하 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.
본 고안은 그 선단부가 흡입구에 연결되는 연장관(100), 상기 연장관의 말단부에 그 선단부가 끼워지는 손잡이관(200), 및 상기 손잡이관의 내면부에 설치되는 광감지부(300)로 구성되어 있다.The present invention is composed of an extension tube 100, the front end of which is connected to the suction port, the handle tube 200 is fitted to the distal end of the extension tube, and the light sensing unit 300 is installed on the inner surface of the handle tube have.
연장관(100)은 그 말단부의 외주변이 상기 손잡이관(200)의 선단부에 소정의 길이만큼 끼워지도록 단턱을 형성하는 그 끝까지 소정의 외경을 가지는 끼움부(110)가 형성된다. 상기 끼움부(111), (112)이 뚫려지며, 상기 검지구멍들(111), (112)뒷쪽으로 그 외주면에 링홈(114)이 파여진다. 또, 상기 링홈(114)에는 시일링(113)이 끼워진다.Extension tube 100 is formed with a fitting portion 110 having a predetermined outer diameter up to its end forming a step so that the outer periphery of the distal end portion of the handle tube 200 is fitted by a predetermined length. The fitting portions 111 and 112 are drilled, and the ring groove 114 is dug into the outer circumferential surface toward the back of the detection holes 111 and 112. In addition, a seal ring 113 is fitted into the ring groove 114.
손잡이관(200)은 그 선단부의 내주면에 상기 연장관(100)의 끼움부(110)가 끼워지되, 끼워졌을 때, 상기 연장관(100)의 내경이 상기 손잡이관(200)의 내경과 일치되도록 소정의 길이만큼 소정의 내용을 가지도록 단턱이지는 끼움부(210)가 형성된다. 상기 끼움부(210)에는 상기 연장관(100)의 말단부가 끼워졌을 때, 상기 연장관의 검지구멍들(111), (112)이 위치되는 장소에 서로 대향되는 두 개의 소자구멍들(211), (212)이 뚫려 있다. 또, 상기 손잡이관(200) 상부 표면에는 손잡이 덮개(220)가 종래의 것과 같이 나사결합되어 있다.The handle tube 200 is fitted to the fitting portion 110 of the extension tube 100 to the inner peripheral surface of the tip portion, when fitted, the predetermined diameter so that the inner diameter of the extension tube 100 is matched with the inner diameter of the handle tube 200 The fitting portion 210 is formed to have a predetermined content as long as. When the distal end of the extension tube 100 is fitted into the fitting portion 210, two element holes 211 and (2) opposed to each other at a position where the detection holes 111 and 112 of the extension tube are positioned ( 212) is open. In addition, the handle cover 220 is screwed to the upper surface of the handle tube 200 as conventional.
광감지부(300)는 상기 손잡이관(200)의 끼움부(210)에, 서로 대향되어 뚫려 있는 소자구멍들(211), (212)에 설치되는 발광소자(310)와 수광소자(320) 및 빛을 검지하는 검지부(330)로 구성된다.The light detecting unit 300 includes a light emitting device 310 and a light receiving device 320 installed in the device holes 211 and 212 which are opposite to each other, to the fitting portion 210 of the handle tube 200. And a detector 330 for detecting light.
상기 발광소자(310)와 수광소자(320)는 상기 소자구멍들(211), (212)의 위치에 설치되되, 상기 손잡이관의 끼움부(210)의 내부 표면과 동일 직선상에, 그 접촉면과 밀접하게 설치된 투광성 덮개가 덮여져 있다. 그 기능과 사상은 종래의 것과 같다. 그러므로 이 부분에 관한 상세한 설명은 생략한다.The light emitting element 310 and the light receiving element 320 are installed at the position of the element holes 211, 212, the same contact surface with the inner surface of the fitting portion 210 of the handle tube It is covered with a transparent cover which is installed closely. Its functions and ideas are the same as in the prior art. Therefore, detailed description of this part is omitted.
본 고안은 상기와 같이 구성되어, 조립될 때에 손잡이관(200)의 끼움부(210)에 상기 연장관의 끼움부(110)가 기밀하게 끼워지며, 이때 상기 연장관(100)과 손잡이관(200)은 동일한 내경 이므로, 동일한 유속을 유도한다.The present invention is configured as described above, the fitting portion 110 of the extension tube is fitted in the airtight portion 210 of the handle tube 200 when assembled, the extension tube 100 and the handle tube 200 Since are the same inner diameter, they lead to the same flow rate.
또한, 상기 조립시에, 상기 연장관(100)에 장착된 시일링(113)은 상기 손잡이관(200)에 설치된 투광성 소자덮개들(311), (312)를 미끄럼접촉하여 닦아준다. 그리고 상기 손잡이관(200)로부터 상기 연장관(1000을 분해 할 때, 상기 시일링(113)은 다시, 투과성 소자덮개들(311), (312)위에 접착된 오물들을 닦아준다. 상기와 같은 구성과 분해, 조립을 인하여, 본 고안의 진공 청소기는 첫째, 종래의 손잡이관(200-A)에 있던, 경사부(201)의 내경 차이로 인하여 발생되었던 와류를 없애게 되며, 따라서 이로인해 발생했던 소음과 흡입손실로 줄여주게 된다. 둘째, 제3도에 도시된 바와같이, 상기 시일링(114)은 상기 두관(100)(200)이 착, 탈될 때마다 상기 소자덮개(311)(312)부를 닦아줌으로 투광성이 지속되기 때문에, 광감지부(300)의 본래 기능을 계속 유지하도록 하는 장점들을 가지게 된다.In addition, at the time of assembly, the sealing ring 113 mounted on the extension pipe 100 wipes the translucent element covers 311 and 312 installed on the handle tube 200 by sliding contact. And when disassembling the extension tube 1000 from the handle tube 200, the sealing ring 113 again wipes the dirt adhered on the transparent element covers 311, 312. With the above configuration Due to disassembly and assembly, the vacuum cleaner of the present invention firstly eliminates the vortex generated due to the difference in the inner diameter of the inclined portion 201, which is in the conventional handle tube 200-A, and thus caused noise. Second, as shown in FIG. 3, the sealing ring 114 is provided with the element covers 311 and 312 whenever the head tubes 100 and 200 are attached and detached. Since the light transmittance is maintained by wiping, it has the advantages of maintaining the original function of the light sensing unit 300.
