본 고안은 진공소제기에 관한 것으로, 특히 모우터 브러쉬호울더에 덮개판을 설치하여 베어링안으로 이물질이 흡입되지 않도록 한 진공소제기의 모우터베어링 보호장치에 관한 것이다.The present invention relates to a vacuum cleaner, and more particularly, to a motor bearing protection device of a vacuum cleaner in which a cover plate is installed in a motor brush holder to prevent foreign substances from being sucked into a bearing.
종래에는 진공소제기의 필터에서 미처 걸러지지 못한 미세한 먼지(쵸크가루)나 브러쉬의 흑연가루가 베어링내부로 흡입되어 베어링의 마모를 가중시켰고 또한, 베어링의 마모로 인하여 모우터가 원활히 작동되지 못하게 됨으로써 모우터의 수명을 단축시키게 된다고 하는 문제가 있었다.Conventionally, the fine dust (choke powder) or the graphite powder of the brush that is not filtered by the vacuum cleaner filter is sucked into the bearing to increase the wear of the bearing, and the wear of the bearing prevents the motor from operating smoothly. There was a problem that the life of the site was shortened.
이에 본 고안은 상기와 같은 문제점을 해소시켜 진공소제기의 필터에서 미쳐 걸러지지 못한 미세한 먼지나 브러쉬의 흑연가루가 상기 덮개판에 부딪혀 베어링 내부로 흡입되지 못하도록 함으로써 베어링의 손상을 방지하고, 이로 인해 모우터의 수명을 연장시켜줄 수 있도록 한 진공소제기의 모우터 베어링 보호장치를 제공함에그 목적이 있다.Therefore, the present invention solves the above problems and prevents the damage of the bearing by preventing the fine dust or the graphite powder of the brush from being caught by the filter of the vacuum cleaner against the cover plate and not being sucked into the bearing. Its purpose is to provide motor bearing protection for vacuum cleaners to extend the service life of the rotor.
상기한 바의 목적을 달성하기 위한 본 고안은 진공소제기의 모우터축이 결합되는 하우징에다 반원형의 덮개판을 갖춘 브러쉬호울더를 나사로 고정시키되, 상기 덮개판 한쪽단부의 윗쪽과 다른쪽 단부의 아래쪽에 각각 제1걸림턱을 형성시키고 상기 베어링 덮개판과 마주보는 위치의 하우징에도 반원형의 덮개만을 갖춘 브러쉬호울더를 나사로 고정시켜주는 한편, 덮개판 한쪽단부의 윗쪽과 다른쪽 단부의 아래쪽에는 상기 제1걸림턱에 대응하는 제2걸림턱을 형성시켜 상기 두 반원형 덮개판의 제1,2걸림턱이 서로 맞물려 원형을 이루는 상태로 베어링 설치부 아랫면에 설치되도록 되어 있다.The present invention for achieving the above object is to fix the brush holder with a semi-circular cover plate to the housing to which the motor shaft of the vacuum cleaner is coupled, with a screw, but at the upper side and the lower end of one end of the cover plate Respectively forming a first catching jaw and fixing the brush holder with a semicircular cover only to the housing in a position facing the bearing cover plate, while the first and the lower end of the cover plate one end; By forming a second catching jaw corresponding to the catching jaw, the first and second catching jaws of the two semicircular cover plates are formed to be installed on the lower surface of the bearing installation part in a state of being engaged with each other.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 진공소제기의 모우터축(1)이 결합되는 하우징(2)에 반원형의 덮개판(3)을 갖춘 브러쉬호울더(4)를 나사로 고정시키되, 상기 덮개판(3) 한쪽 단부의 윗쪽과 다른쪽 단부의 아래쪽에는 각각 제1걸림턱(5)을 형성시키고, 상기 덮개판(3)과 마주보는 위치의 하우징(2)에도 반원형의 덮개판(3')을 갖춘 브러쉬호울더(4')를 나사로 고정시켜주는 한편, 덮개판(3') 한쪽 단부의 윗쪽과 다른쪽 단부의 아래쪽에는 상기 제1걸림턱(5)과 대응하는 제2걸림턱(6)을 각각 형성시켜 상기 제1,2걸림턱(5.6)이 서로 맞물려 결합되도록 되어 있다.According to the present invention, a brush holder (4) having a semicircular cover plate (3) is fixed to a housing (2) to which a motor shaft (1) of a vacuum cleaner is coupled, and the upper side of one end of the cover plate (3) and A brush holder (4 ') having a semicircular cover plate (3') is formed at the lower end of the other end, respectively, and having a first catching jaw (5), and the housing (2) facing the cover plate (3). ) Is fixed with a screw, and the first catching jaw 5 and the second catching jaw 6 corresponding to the first catching jaw 5 are formed at the top of one end of the cover plate 3 'and the bottom of the other end, respectively. , 2 engaging jaw (5.6) is to be engaged with each other.
또한, 상기 브러쉬호울더(4,4')에는 브러쉬(8)가 장착되고, 상기 하우징(2)의 상부에 형성되어 있는 베어링 설치부(7) 내부에는 베어링(9)이 설치되어, 상기 모우터축(1)과 결합된 정류자(10)를 관통한 모우터축(1)의 하단부에는 공지의 안내팬(11)과 임팰러(12)가 설치되어 있는 한편 상기 정류자(10) 외주의 하우징(21)과 모우터하우징(13)의 사이에는 고정자코어(14)가 설치된 구조로 되어 있다.In addition, a brush 8 is mounted to the brush holders 4 and 4 ', and a bearing 9 is installed inside the bearing mounting portion 7 formed on the housing 2, and the mower A well-known guide fan 11 and an impeller 12 are installed at the lower end of the motor shaft 1 penetrating the commutator 10 coupled to the rotor shaft 1, while the housing 21 of the outer periphery of the commutator 10 is provided. ) And the motor housing 13 have a structure in which a stator core 14 is provided.
상기와 같이 구성된 본 고안의 조립과정을 설명하면, 반원형의 덮개판(3,3')을 갖춘 브러쉬호울더(4,4')를 하우징(2) 옆쪽으로 끼워 하우징(2)에 나사로 고정시키는 한편, 상기 두개의 반원형덮개판(3,3')은 모우터축(1)과 결합되는 베어링설치부(7) 아랫면에서 원형을 이루는 상태로 결합되도록 하여 상기 덮개판(3,3')의 바로 위에 베어링(9)이 설치되도록 한다.Referring to the assembly process of the present invention configured as described above, by inserting the brush holder (4,4 ') with a semicircular cover plate (3,3') to the side of the housing (2) to screw to the housing (2) On the other hand, the two semi-circular cover plate (3, 3 ') is coupled to form a circular state on the lower surface of the bearing mounting portion 7 coupled to the motor shaft (1) of the cover plate (3, 3') Allow the bearing 9 to be installed on it.
따라서 브러쉬호울더(4,4')에 장착된 브러쉬(8)의 흑연가루나 공기흡입통로로 들이온 미세한 먼지가 덮개판(3,3')에 부딪혀 베어링의 내부로 들어오지 못하도록 되어 있다.Therefore, the graphite dust of the brush 8 mounted on the brush holders 4 and 4 'or the fine dust introduced into the air suction passage hit the cover plates 3 and 3' so as not to enter the inside of the bearing.
이상의 설명에서와 같이 본 고안은 2개의 반원형덮개판(3,3')을 브러쉬호울더(4,4')에 고정 설치함으로써 모우터축(1)과 결합되는 베이링설치부(7)의 내부에 이물질이 흡입되지 않도록 하여 베어링(9)의 손상을 방지하고, 이 결과로 모우터에 무리가 가지 않도록 하여 모우터의 수명을 연장시켜줄 수 있을 뿐만 아니라 제1,2걸림턱(5,6)에 의해 브러쉬호울더(4,4')를 하우징(2)에 신속하고 정확하게 결합할 수 있어 전반적인 조립시간을 단축케 하는 효과가 있다.As described above, the present invention fixes the two semicircular cover plates 3 and 3 'to the brush holders 4 and 4' so that the inside of the bearing installation part 7 is coupled to the motor shaft 1. This prevents damage to the bearings 9 by preventing foreign substances from being sucked into them, and as a result, the motors are not overwhelmed to extend the life of the motors, as well as the first and second locking jaws (5, 6). By the brush holder (4, 4 ') can be quickly and accurately coupled to the housing (2) has the effect of reducing the overall assembly time.
