본 발명은 직결식 세탁기의 모우터 구조에 관한 것으로, 특히 베어링지지부와 로터프레임의 사이에 결합되어 그 간격을 유지시키며 세탁축을 지지하는 세탁축지지부재의 구조 개선에 관한 것이다.The present invention relates to a motor structure of a direct type washing machine, and more particularly, to an improvement in the structure of a laundry shaft support member coupled to a bearing support and a rotor frame to maintain its spacing and supporting a laundry shaft.

도1은 종래 드럼세탁기의 구조도로서, 오염된 세탁물을 깨끗하게 세탁하는 세탁내조(I) 및 세탁외조(O)와;1 is a structural diagram of a conventional drum washing machine comprising: a washing inner tank (I) and a washing outer tank (O) for washing contaminated laundry cleanly;

상기 세탁내조(I)가 정, 역회전하며 세탁물을 세탁할 수 있도록 하기 위해 회전력을 전달하는 후단부에 세레이션부(S1)가 형성된 세탁축(S)과;A washing shaft (S) having a serration portion (S1) formed at a rear end portion of the washing inner tank (I) to forward and reverse rotation and transmitting rotational force to wash the laundry;

상기 세탁축(S)에 회전력을 발생시켜 전달하는 모우터(M)로 구성된다.It consists of a motor (M) for generating and transmitting a rotating force to the washing shaft (S).

그리고, 상기 모우터(M)는 내부에 베어링(B)이 결합된 베어링지지부(11)가 일체 성형된 세탁외조 후벽부에 체결되어 고정되는 고정자(1)와;And, the motor (M) and the stator (1) is fastened and fixed to the rear wall portion of the laundry outer tub integrally molded bearing bearing (11) coupled to the bearing (B) therein;

상기 고정자(1)의 외주면에 설치되어 전극차이로 인하여 회전하며, 중앙에 소정 등간격으로 결합공(22) 및 체결공(23)이 구비되고, 그 하면 복수개소에 통풍공(26)이 형성된 로터프레임(21)으로 이루어진 회전자(2)와;The rotor is installed on the outer circumferential surface of the stator 1 and rotates due to the electrode difference, and the coupling hole 22 and the fastening hole 23 are provided at predetermined equal intervals in the center thereof, and a rotor having ventilation holes 26 formed in a plurality of lower surfaces thereof. A rotor 2 made of a frame 21;

상기 회전자(2)의 회전력을 세탁축(S)에 전달하며 베어링지지부(11)와 로터프레임(21) 사이의 간격을 유지시켜주고, 그 하면에 로터프레임(21)의 결합공(22)과 대응결합하는 결합돌기(32)와 체결공(33)이 소정 등간격으로 형성되며 그 내부에 세레이션부(31)가 구비된 세탁축지지부재(3)로 이루어진다.The rotational force of the rotor (2) is transmitted to the washing shaft (S) to maintain the distance between the bearing support 11 and the rotor frame 21, the coupling hole 22 of the rotor frame 21 on the lower surface Coupling protrusion 32 and the fastening hole 33 corresponding to the corresponding is formed at a predetermined equal interval and consists of a washing shaft support member 3 having a serration portion 31 therein.

상기의 구성에 따른 작용효과를 설명하면 다음과 같다.Referring to the effect of the above configuration is as follows.

먼저, 모우터(M)는 고정자(1)에 전원 인가시, 고정자와 회전자 사이의 전자 기적 상호 작용에 의해 발생하는 회전력에 의해 회전하게 되고, 상기 회전자(2)의 로터프레임(21)에 결합 고정된 세탁축지지부재(3)도 회전하게 됨과 동시에 세탁축지지부재(3)의 내부와 세탁축(S)의 하부에 형성된 세레이션부(31),(S1)에 의해 회전자(2)의 회전력이 세탁축(S)에 전달됨과 동시에 세탁축(S)의 상부에 결합된 세탁내조(I)도 회전력을 전달받아 회전하며 세탁물을 세탁하게 된다.First, the motor M is rotated by the rotational force generated by the electromagnetic interaction between the stator and the rotor when power is applied to the stator 1, the rotor frame 21 of the rotor (2) Rotating the washing shaft support member (3) coupled to and fixed to the rotor at the same time the serration portion (31), (S1) formed inside the washing shaft support member (3) and the lower portion of the washing shaft (S) At the same time as the rotational force of 2) is transmitted to the washing shaft S, the washing inner tank I coupled to the upper portion of the washing shaft S also receives the rotational force and rotates to wash the laundry.

이때, 상기 베어링지지부(11)와 로터프레임(21) 사이에 결합된 세탁축지지부재(3)는 절연성 수지재질로 형성되어 있기 때문에, 상기 고정자(1)의 코일부와 회전자(2)의 로터프레임(21) 사이의 절연이 파괴될 경우에도 세탁축(S)으로는 전류가 흐르지 않아 세탁외조(O)의 내부에 담겨진 세탁수에 전류가 흐를 수 없으므로 안전사고가 방지된다.At this time, since the laundry shaft support member 3 coupled between the bearing support 11 and the rotor frame 21 is formed of an insulating resin material, the coil part and the rotor 2 of the stator 1 Even when the insulation between the rotor frame 21 is broken, since no current flows through the washing shaft S, current cannot flow in the wash water contained in the washing tub O, thereby preventing safety accidents.

그리고, 상기 세탁축지지부재(3)는 모우터(M)의 진동을 저감시켜 세탁축(S)에 전달하기 때문에 세탁외조의 진동 및 이에 따른 소음을 줄여준다.In addition, the laundry shaft support member 3 reduces the vibration of the motor M and transmits the washing shaft S to the washing shaft S, thereby reducing the vibration of the washing tub and the noise thereof.

그러나, 기존의 세탁축지지부재는 수지재질로만 이루어짐으로 인해 강도측면에서 내구성이 약한 단점이 있었다.However, the conventional laundry shaft support member has a weak durability in terms of strength because it is made of a resin material only.

즉, 단순히 수지재질로만 되어 있는 경우에는 세탁축지지부재가 금속재로만 이루어진 경우에 비해 비록 절연성능과 진동 감소측면에서는 유리하지만 부품의 강도가 약해 내구성 측면에서는 불리한 점이 있다. That is, when the resin shaft is simply made of a resin material, the laundry shaft support member is advantageous in terms of insulation performance and vibration reduction, but it is disadvantageous in terms of durability because it is advantageous in terms of insulation performance and vibration reduction.

그리고, 세탁축지지부재가 수지재질로만 이루어질 경우에는 각 성형 부위의 두께가 지나치게 두꺼워지게 되고, 이는 사출성형후의 냉각에 많은 시간이 소요되고 각 부분에서의 냉각속도 차를 유발시켜 세탁축지지부재의 정확한 성형이 이루어 지기 곤란한 단점이 있을 수 있다.In addition, when the laundry shaft support member is made of only a resin material, the thickness of each molding part becomes too thick, which takes a lot of time for cooling after injection molding and causes a difference in cooling speed in each part of the laundry shaft support member. There may be drawbacks that are difficult to achieve precise molding.

본 발명은 이와 같은 문제점을 해결 보완하기 위한 것으로서, 모우터의 고정자 코일부와 회전자 로터프레임 사이의 절연이 파괴되어도 세탁축에까지 전류가 흐르는 것을 차단하여 안전사고가 발생되는 것을 방지하도록 함과 더불어 모우터의 진동이 세탁축에 전달되는 것을 효과적으로 방지하면서도 세탁축지지부재의 내구성을 향상시킬 수 있는 세탁축지지부재를 구비한 직결식 세탁기의 모우터 구조를 구현함에 그 목적이 있다.The present invention is to solve and solve the above problems, and even if the insulation between the stator coil portion and the rotor rotor frame of the motor is broken to prevent the flow of current to the washing shaft to prevent the occurrence of a safety accident It is an object of the present invention to implement a motor structure of a direct type washing machine having a washing shaft support member that can effectively prevent the vibration of the motor from being transmitted to the washing shaft and improve the durability of the washing shaft support member.

그리고, 상기 절연성 체결부재(4)는, 예를 들어, 도시된 바와 같이 금속재질의 볼트 외면에 수지재질의 절연성 코팅층(40)이 형성된 것이거나, 아예 전체 재질이 플라스틱 재질로 된 것일 수 있다.The insulating fastening member 4 may include, for example, an insulating coating layer 40 made of a resin material formed on an outer surface of a metal bolt, or may be made of a plastic material as a whole.

한편, 상기 세탁축지지부(3b) 또는 절연 가스켓(3a)은 평면에서 볼 때 대략 원판형을 이루게 되나, 반드시 이에 한정되는 것은 아니다.On the other hand, the washing shaft support 3b or the insulating gasket 3a is formed in a substantially disk shape in plan view, but is not necessarily limited thereto.

상기와 같은 구성에 따른 작용효과를 설명하면 다음과 같다.Referring to the effects of the configuration as described above are as follows.

로터프레임(21)에 세탁축지지부재(3) 조립시, 먼저, 로터프레임(21)의 허브부에 형성된 결합공(22)으로 결합돌기(32)를 삽입시켜 절연 가스켓(3a)을 로터프레임(21) 내측면과 밀착시킨다.When assembling the laundry shaft support member 3 to the rotor frame 21, first, the coupling protrusion 32 is inserted into the coupling hole 22 formed in the hub of the rotor frame 21 to insert the insulating gasket 3a into the rotor frame. (21) It is in close contact with the inner surface.

이와 같이 된 상태에서 금속재질의 세탁축지지부(3b)를 절연 가스켓(3a)에 형합시킨 다음, 절연재질의 체결부재(4)를 세탁축지지부(3b) 및 절연 가스켓(3a)의 통공(33)(34)을 통과하여 체결공(23)에 체결되도록 하면 세탁축지지부재(3)는 로터프레임(21)에 견고하게 결합된다.In this state, the metal washing shaft support part 3b is molded into the insulating gasket 3a, and then the fastening member 4 of the insulating material is connected to the laundry shaft support part 3b and the insulating gasket 3a. When passed through the (34) to be fastened to the fastening hole 23, the washing shaft support member (3) is firmly coupled to the rotor frame (21).

이 때, 도 2에 도시된 바와 같이 세탁축(S)은 절연체인 가스켓(3a)로 인해 로터프레임(21)과 접촉되지 않을 뿐 아니라 절연성 체결부재(4)로 인해 유일한 간접 연결통로마저 차단되어 있어 로터프레임(21)에 전류가 흘러도 세탁축(S)에는 전류가 흐르지 않게 된다.At this time, as shown in Figure 2, the washing shaft (S) is not only in contact with the rotor frame 21 due to the gasket (3a) as an insulator, but also the only indirect connection path is blocked by the insulating fastening member (4) Therefore, even if a current flows in the rotor frame 21, a current does not flow in the washing shaft S.

즉, 상기 모우터(M)의 고정자(1) 코일부와 회전자(2)의 로터프레임(21)에 절연이 파괴되어 로터프레임(21)에 전류가 흐르게 되어도, 절연 가스켓(3a) 및 절연 성 체결부재(4)로 인해 로터프레임(21)과 세탁축지지부(3b) 사이의 전기적 연결이 차단되므로 전류가 세탁축(S)으로 전달되지 못해 안전사고를 미연에 방지할 수 있게 되는 것이다.That is, even if the insulation is destroyed in the coil part of the stator 1 of the motor M and the rotor frame 21 of the rotor 2 and a current flows in the rotor frame 21, the insulating gasket 3a and the insulation Since the electrical fastening member 4 blocks the electrical connection between the rotor frame 21 and the washing shaft support part 3b, current cannot be transferred to the washing shaft S, thereby preventing safety accidents.

요컨대, 본 발명에서는 세탁축지지부재(3)를 금속재 및 수지재의 개별 피스로 분리 구성하면서 체결부재를 절연성을 갖는 것을 사용함으로써 전체적으로는 강도를 보강시킴과 동시에 절연성능을 부여하여, 로터프레임(21)에 전류가 흘러도 세탁축(S)으로 전류가 전달되는 것을 차단하여 안전사고가 발생되는 것을 방지하며 사용자를 보호할 수 있게 되는 것이다.In other words, in the present invention, by separating the laundry shaft support member 3 into individual pieces of metal and resin, by using the fastening member having insulation, the rotor frame 21 is strengthened as a whole and the insulation performance is imparted. ) Even if current flows to the washing shaft (S) to prevent the transmission of current to prevent safety accidents will be able to protect the user.

또한, 종래에는 상기 진동이 세탁축(S)에 전달됨으로 인하여 발생된 소음에 의해 사용자에게 제품에 대한 신뢰성을 저하시키게 되었으나, 본 발명에서는 상기 모우터(M)에서 발생된 진동이 세탁축지지부재(3)를 통해 세탁축(S)으로 전달되는 바, 상기 전달된 진동은 철재인 로터프레임(21)과는 다른 진동모드를 갖는 수지재질의 절연 가스켓(3a)에 의해 감쇠되어 세탁축(S)으로 전달됨으로써, 소음발생이 효과적으로 차단됨으로 인해, 사용자에게 제품에 대한 신뢰성을 향상시킬 수 있게 된다.In addition, in the related art, the vibration of the vibration generated from the motor M is reduced in the user's reliability by the user due to the noise generated due to the vibration transmitted to the washing shaft S, in the present invention. It is transmitted to the washing shaft (S) through (3), the transmitted vibration is attenuated by a resin insulating gasket (3a) of a resin material having a vibration mode different from the rotor frame 21 is made of steel washing shaft (S) By passing through), the noise is effectively blocked, it is possible to improve the reliability of the product to the user.

또한, 상기 로터프레임(21)의 하면에는 통풍공(26)과 냉각팬(25)이 복수개소에 형성되어 있는 바, 이때 상기 통풍공(26)은 냉각팬(25)을 직각으로 상향 절곡시키게 되면 자연적으로 형성되며, 상기 냉각팬(25)과 통풍공(26)에 의해 모우터(M)의 열이 냉각됨으로서, 종래 통풍공(26)에만 의존하여 냉각하는 방식에 비해 월등한 냉각효과를 갖게되어 모우터(M)의 성능 및 수명을 연장시킬 수 있게 된다. In addition, the lower surface of the rotor frame 21 is formed with a plurality of vent holes 26 and the cooling fan 25, wherein the vent holes 26 are naturally bent when the cooling fan 25 is bent upward at a right angle Is formed in the cooling fan 25 and the ventilation holes 26 by the heat of the motor (M), by cooling only has a superior cooling effect compared to the conventional cooling method depending only on the ventilation holes 26 It is possible to extend the performance and life of (M).                     

그리고, 상기 통풍공(26)과 냉각팬(25) 사이사이에는 돌출 형성된 강도보강용 요철부(27)가 형성되고, 그 하면에는 배수공(28)이 형성되어 있는바, 상기 로터프레임(21)에 떨어진 세탁수는 배수공(28)이 형성된 강도보강용 요철부(27)에 모여 배수공(28)으로 배출된다.In addition, between the ventilation hole 26 and the cooling fan 25, a protrusion-strength convex portion 27 protrudingly formed is formed, and a drain hole 28 is formed on the lower surface of the rotor frame 21. The washed water is collected in the strength reinforcing concave-convex portion 27 in which the drain hole 28 is formed and discharged into the drain hole 28.

이때, 상기 로터프레임(21)에 떨어진 세탁수가 외부로 배출됨으로서, 상기 모우터(M)의 온도상승시 증발한 세탁수가 모우터로 유입됨에 기인한 모우터(M)의 동작상태 불량을 방지하게 되어 세탁기의 세탁성능을 최적 상태로 유지할 수 있도록 한다.At this time, the washing water dropped to the rotor frame 21 is discharged to the outside, to prevent the operation state of the motor (M) due to the washing water evaporated when the temperature of the motor (M) rises into the motor. Therefore, the washing performance of the washing machine can be maintained in an optimal state.

이와 같이 된 본 발명은 세탁축지지부재의 강성을 높이면서도 가스켓에 의해 절연이 이루어지도록 함으로써, 모우터의 고정자 코일부와 회전자의 로터프레임에 절연이 파괴되어도 세탁축지지부재에 의해 전류가 세탁축으로 전달되는 것을 차단하여 안전사고를 방지할 수 있게 된다.According to the present invention, while the rigidity of the washing shaft support member is made to be insulated by the gasket, the current is washed by the washing shaft support member even if the insulation is destroyed in the stator coil part of the motor and the rotor frame of the rotor. It prevents the safety accident by blocking the transmission to the shaft.

또한, 본 발명은 모우터의 진동이 세탁축으로 전달되는 현상이 다른 진동모드를 갖는 수지재질의 가스켓에 의해 저감됨으로써 소음 발생을 줄일 수 있어, 사용자에게 제품에 대한 신뢰성을 향상시킬 수 있는 유용한 효과를 갖는다.In addition, the present invention is a phenomenon that the vibration of the motor is transmitted to the washing shaft is reduced by the resin material gasket having a different vibration mode can reduce the generation of noise, a useful effect that can improve the reliability of the product to the user Has
