Description
본 발명은 진공청소기에 관한 것으로, 보다 상세하게는 피청소면의 먼지를 보다 효율적으로 비산시키기 위해 솔부재의 구조를 개선한 진공청소기의 회전 브러시에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a rotary brush of a vacuum cleaner having an improved structure of a brush member in order to more efficiently scatter dust on a surface to be cleaned.
업라이트 청소기 또는 캐니스터형 청소기의 흡입브러시에는 피청소면의 먼지를 비산시켜 청소효율을 향상시킬 수 있는 회전 브러시가 구비될 수 있다. 상기 회전 브러시는, 다수의 솔부재가 나선형으로 식모되어 있는데, 이 솔부재의 강성에 따라 청소효율이 좌우된다. The suction brush of the upright cleaner or the canister type cleaner may be provided with a rotary brush to improve cleaning efficiency by scattering dust on the surface to be cleaned. In the rotary brush, a plurality of brush members are implanted in a spiral shape, and the cleaning efficiency depends on the rigidity of the brush member.
즉, 상기 솔부재의 강성이 일정 수준이상이 되도록 그 길이 신장시키고, 굵기를 증가시킬 경우 청소효율은 향상된다. 그러나, 이 경우 피청소면, 예컨대 카페트와 같은 섬유재질의 피청소면일 경우에는 상기 솔부재와의 마찰에 의해, 카페트 표면의 마모도가 증가할 수 있다. 이러한 피청소면의 마모를 방지하기 위해 상기 솔부재의 강성을 낮출 경우, 예컨대 보다 짧은 길이와 얇은 굵기의 솔부재를 사용하게 되면, 피청소면의 마모는 방지되지만 청소효율이 떨어지게 되는 문제점이 있다.In other words, when the length of the brush member is increased to a certain level or more, and the thickness thereof is increased, the cleaning efficiency is improved. However, in this case, in the case of the surface to be cleaned, for example, the surface to be cleaned of a fiber material such as a carpet, wear of the carpet surface may increase due to friction with the brush member. When the stiffness of the brush member is lowered to prevent the wear of the surface to be cleaned, for example, when a brush member having a shorter length and a thin thickness is used, wear of the surface to be cleaned is prevented but the cleaning efficiency is lowered.

When the upright type vacuum cleaner 10 is driven by a motor driven to generate suction power, dust and dirt on the cleaning surface are sucked through the suction port of the suction port 20 together with external air and collected in the dust bag of the dust collecting chamber.
한편, 카펫이나 마루 등의 청소면 깊숙히 달라붙은 이물질을 제거하기 위해 흡입구체(20)에는 회전 브러시(100)가 구비된다. 회전 브러시(100)는 구동벨트(22)에 연결되어 상기 모터에 의해 구동되도록 흡입구체(20)의 하우징(21)에 회전 가능하도록 설치된다.On the other hand, the suction inlet 20 is provided with a rotary brush 100 to remove the foreign matter stuck to the cleaning surface, such as carpet or floor. The rotary brush 100 is connected to the drive belt 22 and installed to be rotatable in the housing 21 of the inlet body 20 to be driven by the motor.
도 2는 본 발명에 의한 진공청소기의 회전 브러시(100)를 나타낸 사시도이다. 도시된 바와 같이, 회전 브러시 본체(110)는, 그 외주면이 나선형으로 꼬인 상태로 형성되며, 그 최외곽에는 다수의 솔부재(120)가 식모되는 솔부재 안착홈(111)이 일정 간격으로 마련된다.2 is a perspective view showing a rotating brush 100 of the vacuum cleaner according to the present invention. As shown, the rotating brush body 110, the outer peripheral surface is formed in a spiral twisted state, the outermost is provided with a brush member seating groove 111 is a plurality of brush members 120 are planted at regular intervals. do.
상기 솔부재 안착홈(111)에는, 다수의 솔부재(120)가 식모되어 있다. 도 3 및 도 4는 상기 솔부재(120)가 식모된 A부분을 확대하여 나타낸 도면으로, 서로다른 굵기의 제 1 및 제 2 솔부재(121)(122)가 식모된 상태를 나타낸 도면이다. 상기 제 1 솔부재(121)의 굵기는 상기 제 2 솔부재(122)의 굵기보다 굵게 마련되는 것이 바람직한데, 상기 제 1 솔부재(121)는, 0.25mm 정도의 굵기를 가지며, 상기 제 2 솔부재(122)는 0.20mm의 굵기를 가지는 것이 좋다. 한편, 상기 제 1 및 제 2 솔부재(121)(122)는, 균일한 비율(50:50)로 식모되는 것이 바람직하다. 상기 제 1 및 제 2 솔부재(121)(122)의 굵기는 상기한 수치로 한정하는 것은 아니며, 상기 제 1 솔부재(121)는, 0.225~0.275mm 사이의 값을 가지며, 상기 제 2 솔부재(122)는, 0.18~0.220mm 사이의 값을 가지는 범위 내에서 상기 제 1 솔부재(121)가 상기 제 2 솔부재(122)의 굵기보다 굵으면 족하다.A plurality of brush members 120 are planted in the brush member seating grooves 111. 3 and 4 are enlarged views showing a portion A in which the brush member 120 is planted, showing a state in which the first and second brush members 121 and 122 having different thicknesses are planted. The thickness of the first sole member 121 is preferably provided to be thicker than the thickness of the second sole member 122, the first sole member 121 has a thickness of about 0.25mm, the second Brush member 122 may have a thickness of 0.20mm. On the other hand, it is preferable that the first and second brush members 121 and 122 are planted at a uniform ratio (50:50). The thickness of the first and second sole members 121 and 122 is not limited to the above-described numerical values, and the first sole member 121 has a value between 0.225 and 0.275 mm, and the second sole The member 122 is sufficient if the first sole member 121 is thicker than the thickness of the second sole member 122 within a range having a value between 0.18 and 0.220 mm.
상기 제 1 및 제 2 솔부재(121)(122)가 상기와 같은 범위의 굵기를 가지는 이유는, 만일 상기 제 1 솔부재(121)가 0.275mm 이상의 굵기를 가질 경우에는 청소효율은 증가하지만, 카페트와 같은 직물 바닥면의 마모가 심해져, 피청소면을 손상시킬 수 있으며, 상기 제 2 솔부재(122)가 0.225mm 이하의 굵기를 가질 경우에는 피청소면의 손상은 방지할 수 있으나, 상기 피청소면에 부착된 먼지를 타격하여 비산시키지 못하기 때문에 청소효율이 떨어지기 때문이다.The reason why the first and second brush members 121 and 122 have a thickness in the above range is that if the first brush member 121 has a thickness of 0.275 mm or more, the cleaning efficiency is increased. Abrasion of the bottom surface of the fabric, such as carpet, may be damaged, and the surface to be cleaned may be damaged. If the second brush member 122 has a thickness of 0.225 mm or less, damage to the surface to be cleaned may be prevented. This is because the cleaning efficiency is lowered because the dust attached to it cannot be blown and scattered.
또한, 상기 제 1 및 제 2 솔부재(121)(122)는 서로 다른 색을 가지도록 제작되어 사용자가 시각적으로 상기 제 1 및 제 2 솔부재(121)(122)를 구분할 수 있도록 하는 것이 좋다.In addition, the first and second sole members 121 and 122 may be manufactured to have different colors so that a user may visually distinguish the first and second sole members 121 and 122. .
이하, 도 1 내지 도 4을 참조하여 본 발명의 바람직한 실시예에 의한 진공청소기의 회전 브러시(100)를 구비한 진공청소기(10)의 동작을 설명한다.1 to 4, the operation of the vacuum cleaner 10 having the rotary brush 100 of the vacuum cleaner according to the preferred embodiment of the present invention will be described.
본 발명에 의한 회전 브러시(100)는, 진공청소기의 흡입구체(20) 측에 회동가능하게 설치되어 피청소면의 먼지를 상기 솔부재(120)가 타격하여 공중에 비산시켜 청소효율을 향상시키는 역할을 한다.The rotary brush 100 according to the present invention is rotatably installed on the suction inlet 20 side of the vacuum cleaner, and serves to improve cleaning efficiency by hitting the brush member 120 against the dust to be cleaned to the air. Do it.
상기 회전 브러시(100)에는, 그 외주면을 따라 다수의 솔부재(120)가 식모되어 있는데, 바닥면, 특히 카페트와 같이 직물로 이루어진 피청소면의 경우에는 굵고 긴 솔부재를 사용하는 것이 청소 효율을 향상시킬 수 있다. 그러나, 상기 솔부재(120)의 굴기와 길이가 증가할 수록 상기 피청소면 표면의 마모 정도가 증가하여 그 표면을 손상시킬 수 있다.In the rotary brush 100, a plurality of brush members 120 are planted along the outer circumferential surface thereof, and in the case of the surface to be cleaned, which is made of a fabric such as a carpet, a thick brush member is used for cleaning efficiency. Can be improved. However, as the length and length of the brush member 120 increase, the degree of wear on the surface to be cleaned increases, which may damage the surface.
따라서, 도 3 및 도 4에 도시된 바와 같이, 서로 굵기가 다른 제 1 및 제 2 솔부재(121)(122)를 동일한 비율로 식모한다. 이 경우, 상기 제 1 솔부재(121)의 굵기를 상기 제 2 솔부재(122)의 굵기보다 굵게 형성하여, 상기 제 1 솔부재(121)는 바닥면을 타격하는 역할을 하고, 상기 제 2 솔부재(122)는 바닥면을 쓸어주는 역할을 한다. 즉, 상기 제 1 솔부재(121)의 굵기만으로 상기 솔부재(120)를 형성하는 것에 비해, 피청소면과의 마찰력을 줄일 수 있기 때문에 카페트와 같은 직물 재질의 피청소면의 마모발생을 방지할 수 있다. 또한, 서로다른 굵기의 솔부재(120)를 사용하기 때문에 하나의 솔부재(120)로 타격과 쓸어주는 작업을 동시에 수행할 수 있어 보다 효율적으로 청소작업을 수행할 수 있다.Therefore, as shown in FIGS. 3 and 4, the first and second sole members 121 and 122 having different thicknesses are planted at the same ratio. In this case, the thickness of the first sole member 121 is made thicker than the thickness of the second sole member 122, the first sole member 121 serves to hit the bottom surface, the second Brush member 122 serves to sweep the bottom surface. That is, compared with forming the sole member 120 only by the thickness of the first sole member 121, since frictional force with the surface to be cleaned can be reduced, wear occurrence of the surface to be cleaned of a textile material such as carpet can be prevented. have. In addition, since the use of the brush member 120 of different thicknesses can be performed at the same time to blow and sweep with one brush member 120 can perform a more efficient cleaning operation.
이상과 같은 본 발명에 의한 회전 브러시 및 이를 구비하는 진공청소기에 의하면, 굵은 솔부재와 얇은 솔부재가 하나의 솔부재 삽입공에 식모되기 때문에, 피청소면의 마모를 줄일 수 있음과 아울러 청소 효율도 향상시킬 수 있다.According to the rotary brush and the vacuum cleaner having the same according to the present invention as described above, since a thick brush member and a thin brush member are planted in one brush member insertion hole, wear of the surface to be cleaned can be reduced and cleaning efficiency is also increased. Can be improved.
