유니버셜 모터의 하우징 구조{The Housing Structure of Universal Moter}The Housing Structure of Universal Moter

본 발명은 세탁기용 모터로 이용되는 유니버셜 모터 하우징 구조에 관한 것으로, 더 상세하게는 유니버셜 모터의 리어 하우징에 브러쉬 홀더를 일체형으로 구성하되, 타코미터와 브러쉬 관련 부재들의 조립이 간편, 용이하게 이루어질 수 있는 유니버셜 모터의 개선된 하우징 구조에 관한 것이다.The present invention relates to a structure of a universal motor housing used as a motor for a washing machine. More specifically, the brush holder is integrally formed on the rear housing of the universal motor, and the assembly of the tachometer and brush-related members can be easily and easily performed. An improved housing structure of a universal motor is disclosed.

일반적으로, 유니버셜 모터는 무부하 회전수가 높고, 고속회전을 용이하게 얻을 수 있어 고출력이 요구되는 세탁기 등에 사용되는 것으로, 하우징 타입과 프레임 타입으로 구분되고, 상기 하우징 타입은 모터를 하우징 내부에 설치하여 이물의 침투를 차단하는 것이고, 상기 프레임 타입은 모터를 외부에 설치하여 방열효과를 높이고자 하는데 있다.In general, a universal motor is used for a washing machine that requires high output due to a high no-load rotation speed and high speed rotation, and is divided into a housing type and a frame type, and the housing type is provided with a foreign body by installing the motor inside the housing. This is to block the penetration of the frame type is to increase the heat dissipation effect by installing the motor outside.

상기 하우징 타입의 유니버셜 모터는 전후 양측에 일정한 간격을 유지하는 전면 하우징과 후면 하우징이 설치되고, 그 사이에 스테이터, 로터, 회전축, 커뮤테이터와 커뮤테이터에 전류를 공급하는 브러쉬 어셈블리와, 타코미터를 포함하고 있다. The housing-type universal motor is provided with a front housing and a rear housing at regular intervals at both front and rear sides, and between the stator, the rotor, the rotating shaft, the brush assembly for supplying current to the commutator and the commutator, and a tachometer. Doing.

상기 후면 하우징에는 상기 브러쉬 어셈블리를 장치함에 있어, 크게 2가지로 나누어 볼 수 있는 것으로, 하나는 후면 하우징 상에 브러쉬 어셈블리를 나사로 체결하여 조립 고정하는 구조이고, 다른 하나는 후면 하우징과 브러쉬 홀더가 일체형으로 되어 브러쉬를 삽입한후 브러쉬 인출선을 단자처리하여 모터 하우징의 돌기에 나사 체결 고정하고, 토션스프링은 스프링 지지돌기에 삽입하여 브러쉬를 밀어 주는 하우징 구조로 이루어져 있다.In the rear housing, the brush assembly can be divided into two types, one of which is a structure for fastening and assembling the brush assembly on the rear housing by screwing, and the other of the rear housing and the brush holder are integrated. After inserting the brush, the brush lead wire is terminal-processed and screw-fastened to the protrusion of the motor housing, and the torsion spring is inserted into the spring supporting protrusion to push the brush.

이상의 구조중 전자는 후면 하우징에 각각 나사를 체결하여 조립 고정시키는 번거로움으로 생산성이 저감되는 문제점이 있었고, 후자는 인출선 및 토션스프링이 노출되어 감전의 위험이 있는 등의 문제점이 있었다. In the above structure, the former had a problem in that the productivity was reduced due to the trouble of assembling and fixing the screws to the rear housing, and the latter had a problem such as exposure of the leader line and the torsion spring and the risk of electric shock.

As shown, the present invention forms a brush holder 12 that can insert the brush 11 on both opposite sides of the universal motor housing 10 integrally with the housing 10, the brush holder 12 In inserting and fixing the brush 11 and the coil spring 13 to the (), one end of the pigtail 15 is inserted and connected to the brush proximal end 14, the other end of the pigtail 15 and the insulating material The lead wire 16 coated with the wire is connected by welding, and the lead wire 16 has a structure penetrating the coil spring 13 and the cover 17 to protrude on the outer surface of the cover 17. 18) and the cover 17 is formed by a groove 20 formed at the front end of the brush holder 12 by protruding the connecting hook 19 from the side of the cover 17. Consists of a structure that is opened and closed from the brush holder 12, the tachometer ( The support 22 of the "U" shape protrudes on both sides of the 21, and the support grooves 23 are formed on both sides of the rear housing 1 at the position where the tachometer 21 is assembled. Earth 22 is made of a structure that is assembled, detached to the support groove 23.

이상에서 설명하고 있는 바와 같이. 본 발명은 유니버셜 모터의 후면 하우징에 있어서, 조립의 공정수를 저감시킴과 동시에 감전의 위험성을 근원적으로 해결한 효과가 있고, 기구적 구조의 변경으로 기계적 강도가 보강된 효과가 있으며, 생산성 및 내구성이 있는 효과가 있다.As explained above. The present invention has the effect of reducing the number of steps of the assembly and at the same time fundamentally solved the risk of electric shock in the rear housing of the universal motor, the mechanical strength is strengthened by changing the mechanical structure, productivity and durability This has the effect.

이상과 같은 구조로 이루어진 본 발명의 구체적 설명은 다음과 같다.Detailed description of the present invention having the above structure is as follows.

도 1에 도시된 바와 같이, 유니버셜 모터 하우징(10)의 양쪽 대향측에 일체로 형성된 브러쉬 홀더(12)로 상기 브러쉬(11) 및 코일스프링(13)을 삽입시키고 고정 조립함에 있어서, 피그테일(15)의 일단이 브러쉬 기단(14)에 삽입되어 연결되어 있고, 상기 피그테일(15)의 타단과 절연재로 피복된 인출선(16)은 용접으로 연결되어 있으며 이 인출선(16)이 상기 코일스프링(13)과 커버(17)를 관통한 후, 후방으로 끌어 당겨, 상기 커버(17)의 외면에 돌출된 고리(18)에 결속하여 가 조립한다.As shown in FIG. 1, when the brush 11 and the coil spring 13 are inserted into and fixed to the brush holder 12 integrally formed on opposite sides of the universal motor housing 10, the pigtail ( One end of 15) is inserted into and connected to the brush base 14, and the other end of the pigtail 15 and the lead wire 16 coated with an insulating material are connected by welding, and the lead wire 16 is connected to the coil. After passing through the spring 13 and the cover 17, and pulled backward, it is bound to the ring 18 protruding from the outer surface of the cover 17, and assembled.

이와 같은 가 조립상태에서 후면 하우징을 완전히 조립한 후에 상기 인출선(16)을 고리에서 해지 시키면 상기 코일스프링(13)에 의해 브러쉬(11)가 전방으로 밀착되어 정류자에 전원이 인가될 수 있도록 접촉되어 브러쉬(11)의 조립공정이 마무리된다.After the assembly of the rear housing is completely assembled in this temporary assembly state, the lead wire 16 is released from the ring so that the brush 11 is brought into close contact by the coil spring 13 so that power can be applied to the commutator. Then, the assembly process of the brush 11 is completed.

이상과 같은 가 조립후 조립의 공정를 거처야 하는 이유는 후면 하우징(10)을 조립한 후 상기 브러쉬(11) 및 코일스프링(13)을 브러쉬 홀더(12)에 삽입시키는 경우에는 상기 브러쉬(11)가 후면 하우징(10) 내측에 조립되어 있는 회전자의 정류자에 접촉이 된채 코일스프링(13)의 탄지로 압지되도록 조립해야 하는 공정에 어려움이 많았고, 불편했음에도 성공적으로 잘 이루어지지 못했기 때문이다. The reason for having to go through the assembly process after the temporary assembly as described above is that when the brush 11 and the coil spring 13 are inserted into the brush holder 12 after the rear housing 10 is assembled, the brush 11 is used. This is because the process to be assembled so that the contact with the commutator of the rotor is assembled in the rear housing 10 inside the coil spring 13, there are a lot of difficulties, because the inconvenience was not successfully achieved.

따라서, 이상과 같은 가 조립공정 후, 후면 하우징(10)을 조립하고, 상기 인출선(16)을 풀어 줌으로서, 코일스프링(13)의 탄지력이 유지되어 상기 정류자와 브러쉬(11)의 접촉이 유지된다.Therefore, after the temporary assembly process as described above, the rear housing 10 is assembled and the lead wire 16 is released to maintain the holding force of the coil spring 13 so that the commutator contacts the brush 11. Is maintained.

상기 커버(17)의 측면에 돌출된 연결걸이(19)는 상기 브러쉬 홀더(12) 선단면에 형성된 요홈(20)에 끼워져 걸렸다, 해지되며 상기 커버(17)가 상기 브러쉬 홀더(12)로부터 개폐된다. The connecting hook 19 protruding from the side of the cover 17 is caught by the groove 20 formed in the front end surface of the brush holder 12, and is terminated and the cover 17 is opened and closed from the brush holder 12. do.

또한, 타코미터(21)의 양측면에 "U"자 형상으로 돌출된 지지구(22)는 상기 타코미터(21)가 조립되는 위치의 후면 하우징(1) 양측면에 형성된 지지홈(23)에 끼워졌다, 해지되며 상기 지지구(22)가 지지홈(23)에 탈,부착 조립되며 사용된다.In addition, the support 22 which protrudes in a "U" shape on both sides of the tachometer 21 is fitted into the support grooves 23 formed on both sides of the rear housing 1 at the position where the tachometer 21 is assembled. It is terminated and the support 22 is used by being detached and attached to the support groove 23.
