Description
본 고안은 세탁기에 적용되어지는 외전형전동기에 관한 것으로, 더욱 상세하게는 외전형전동기에 냉각팬을 형성하여 세탁기의 작동과정에서 외전형전동기를 효율적으로 냉각시켜줄수 있도록 함으로서 상기 외전형전동기가 과열되는 것을 미연에 방지할수 있도록 한 세탁기용 외전형전동기에 관한 것이다.The present invention relates to an external electric motor that is applied to a washing machine. More specifically, the external electric motor is overheated by forming a cooling fan in the external electric motor to efficiently cool the external electric motor during the operation of the washing machine. The present invention relates to an electric motor for a washing machine, which can be prevented in advance.
일반적으로 세탁기에 적용되어지는 전동기는 하우징내에 장착되어진 로터가 회전하면서 그 회전력에 의해 구동력을 얻게 됨으로서 세탁기를 작동시키는데 주동력원으로 이용되게 된다.In general, an electric motor applied to a washing machine is used as a main power source to operate the washing machine by obtaining a driving force by the rotational force of the rotor mounted in the housing.
그러나 상기 세탁기에 적용되어지는 전동기는 세탁기가 원활하게 작동되기 위해서는 많은 출력이 요구되기 때문에, 최근에는 출력축에 회전력을 전달시키게 되는 로터가 고정자의 외주방향으로 위치되어 전동기의 출력을 향상시킬수 있도록 하는 외전형전동기가 일부적용되어 지고 있는 실정이다.However, since the electric motor applied to the washing machine requires a lot of output in order to operate the washing machine smoothly, the rotor, which transmits the rotational force to the output shaft, is located in the outer circumferential direction of the stator, thereby improving the output of the motor. A typical electric motor is being applied in part.
한편, 상기 외전형전동기의 구조는 첨부된 도면의 도1에 도시된 바와같이, 상단외주면에 플랜지(80)가 장착되어지고 그 외주면에는 스핀샤프트(90)와 베어링(100)이 각각 장착되어지는 출력축(20)과; 상기 출력축(20)의 외주방향에 로터하우징(30)을 매개로 소정의 이격거리를 두고 장착되어지는 로터(50)와; 상기 스핀샤프트(90)의 외주면에 결합되어진 베어링(100)에 그 일측이 결합되면서 상기 로터(50)의 외주방향에 근접배치되는 모터하우징(40)과; 상기 로터(50)와 모터하우징(40)간에 발생되어지는 공간부내에 장착되면서 그 상.하방향으로는 코일(70)이 권취되어지는 고정자(60)로 구성되어, 상기 고정자(60)와 근접배치되어진 로터(50)가 회전하게 되면서 로터하우징(30)을 매개로 출력축(20)을 회전시킬수 있도록 구성되어진 것이다.Meanwhile, as shown in FIG. 1 of the accompanying drawings, the structure of the abduction type motor is provided with a flange 80 mounted on an outer circumferential surface of the top, and a spin shaft 90 and a bearing 100 mounted on the outer circumferential surface thereof, respectively. An output shaft 20; A rotor 50 mounted to the outer circumferential direction of the output shaft 20 at a predetermined distance from the rotor housing 30; A motor housing 40 disposed close to the outer circumferential direction of the rotor 50 while one side thereof is coupled to the bearing 100 coupled to the outer circumferential surface of the spin shaft 90; It is composed of a stator 60 which is mounted in the space portion generated between the rotor 50 and the motor housing 40 while the coil 70 is wound up and down, and is close to the stator 60. As the rotor 50 is disposed to rotate, it is configured to rotate the output shaft 20 via the rotor housing 30.
그러나 상기 세탁기에 적용되어진 종래의 외전형 전동기(10)는, 과열이 발생되는 것을 방지하기 위한 냉각장치가 별도로 구비되어 있지 않아 세탁기의 구동장치를 구동시키기 위한 출력축(20)이 고속으로 회전되는 과정에서 상기 고정자(60)에 가해지는 부하에 의해 상기 고정자(60)의 외주면에 권취되어진 코일(70)이 쉽게 과열되어 외전형전동기(10)의 수명이 단축되어진다는 문제점이 있었다.However, since the conventional abduction type electric motor 10 applied to the washing machine does not have a separate cooling device for preventing overheating, the output shaft 20 for driving the driving device of the washing machine rotates at a high speed. The coil 70 wound around the outer circumferential surface of the stator 60 is easily overheated by the load applied to the stator 60, thereby shortening the life of the external electric motor 10.
이에 본 고안은 상기의 제반 문제점을 해소시키기 위해 안출된 것으로, 본 고안은 외전형전동기의 구조를 개량하여 세탁기의 작동과정에서 외전형전동기가 과열되는 것을 방지하여 그 사용수명을 배가시킬수 있도록 한 세탁기용 외전형전동기를 제공하는데 그 목적이 있는 것이다.Therefore, the present invention was devised to solve the above problems, and the present invention improved the structure of the external electric motor to prevent the external electric motor from being overheated during the operation of the washing machine so as to double its service life. The purpose is to provide an external electric motor.
상기의 목적을 달성시키기 위한 본 고안에 따른 세탁기용 외전형전동기는, 외전형전동기의 고정자와 근접배치된 로우터의 선단에 냉각팬을 구비하여 상기 로우터가 정,역회전됨과 동시에 냉각핀이 정.역회전하면서 외부의 공기를 흡입하고 또한, 내부의 공기를 배출하여 냉각효과를 얻을수 있도록 한 것을 특징으로 한다.According to the present invention for achieving the above object, the abduction type motor for a washing machine includes a cooling fan at the tip of a rotor disposed close to a stator of the abduction type motor, and the rotor is rotated forward and backward and at the same time the cooling fin is fixed. In the reverse rotation, the outside air is sucked, and the inside air is discharged to obtain a cooling effect.

상기와 같이 구성되어진 본 고안에 따른 세탁기용 외전형전동기를 첨부된 도면에 의거하여 상세히 설명한다.On the basis of the accompanying drawings, the electric motor for a washing machine according to the present invention configured as described above will be described in detail.
도2는 본 고안에 따른 세탁기용 외전형전동기의 결합단면도이고, 도3은 상기 도2의 A-A선 단면도로서, 본 고안은 상단외주면에 플랜지(80)가 장착되어지고 그 외주면에는 스핀샤프트(90)와 베어링(100)이 각각 장착되어지는 출력축(20)과; 상기 출력축(20)의 외주방향에 로터하우징(30)을 매개로 소정의 이격거리를 두고 장착되어지는 로터(50)와; 상기 스핀샤프트(90)의 외주면에 결합되어진 베어링(100)에 그 일측이 결합되면서 상기 로터(50)의 외주방향에 근접배치되는 모터하우징(40)과; 상기 로터(50)와 모터하우징(40)간에 발생되어지는 공간부내에 장착되면서 그 상.하방향으로는 코일(70)이 권취되어지는 고정자(60)로 구성되어, 상기 고정자(60)와 근접배치되어진 로터(50)가 회전하게 되면서 로터하우징(30)을 매개로 출력축(20)을 회전시킬수 있도록 구성되어진 것으로 이는 종래의 것과 동일한 구조이다.Figure 2 is a cross-sectional view of the combined electric motor for a washing machine according to the present invention, Figure 3 is a cross-sectional view of the AA line of Figure 2, the present invention is equipped with a flange 80 on the upper outer peripheral surface and the spin shaft 90 on the outer peripheral surface ) And an output shaft 20 to which the bearing 100 is mounted; A rotor 50 mounted to the outer circumferential direction of the output shaft 20 at a predetermined distance from the rotor housing 30; A motor housing 40 disposed close to the outer circumferential direction of the rotor 50 while one side thereof is coupled to the bearing 100 coupled to the outer circumferential surface of the spin shaft 90; It is composed of a stator 60 which is mounted in the space portion generated between the rotor 50 and the motor housing 40 while the coil 70 is wound up and down, and is close to the stator 60. As the rotor 50 is disposed to rotate, the output shaft 20 may be rotated through the rotor housing 30, which is the same as the conventional structure.
그러나, 본 고안은 상기 고정자(60)와 근접배치된 로터(50)의 선단에 시로코팬(S iroco fan)형태의 냉각팬(120)이 일체로 구성되어 진 것으로, 이는 상기 로터(50)가 정,역회전하게 되면 그 상부에 형성되어진 냉각핀(120)이 동시에 정.역회전하면서 외부의 공기를 모터하우징(40)내로 흡입하거나 또는 상기 모터하우징(40)내부의 더운공기를 외부로 신속히 배출하여 로터(50)의 외주방향에 권취되어진 코일(70)을 효율적으로 냉각시켜 줄수 있는 것이며, 또한 상기 모터하우징(40)과 근접배치되는 고정자(60)의 내주방향에는 소정의 배치간격을 두고 냉각홀(110)이 구비됨으로서 냉각효율을 극대화 시킬수 있도록 한 것이다.However, the present invention is that the cooling fan 120 of the Siroco fan (S iroco fan) type is integrally formed at the front end of the rotor (50) close to the stator 60, which is the rotor 50 When forward and reverse rotation, the cooling fins 120 formed on the upper portion rotate forward and reverse at the same time, so that the outside air is sucked into the motor housing 40 or the hot air inside the motor housing 40 is quickly moved to the outside. It is possible to efficiently cool the coil 70 wound in the outer circumferential direction of the rotor 50 by discharging, and a predetermined interval is placed in the inner circumferential direction of the stator 60 disposed close to the motor housing 40. The cooling holes 110 are provided to maximize the cooling efficiency.
상기와 같이 구성되어진 본 고안은, 세탁기를 작동시키기 위해 외전형전동기(130)가 구동되게 되면 상기 외전형정동기(130)의 로터(50)가 일정한 시간을 주기로 정,역구동됨과 동시에 그 상부에 일체로 형성되어진 냉각팬(120)이 정,역구동되게 된다.The present invention, which is configured as described above, when the abduction motor 130 is driven to operate the washing machine, the rotor 50 of the abduction motor 130 is driven forward and backward at regular intervals and at the same time thereon. The cooling fan 120 formed integrally is driven forward and reverse.
이와같이 냉각팬(120)이 정,역구동됨에 따라, 배출 및 흡입압력이 발생하게 되어 상기 모터하우징(40)내의 과열된 공기가 외부로 신속하게 배출됨과 아울러 외부의 차가운 공기가 모터하우징(40)내로 유입됨으로서, 상기 모터하우징(40)내에 장착되어진 고정자(60) 및 코일(70)이 작동되는 동안에 과열되지 않게 되는 것이다.As the cooling fan 120 is driven forward and backward, discharge and suction pressure are generated so that the superheated air in the motor housing 40 is quickly discharged to the outside and the external cold air is discharged to the motor housing 40. By being introduced into it, the stator 60 and the coil 70 mounted in the motor housing 40 are not overheated during operation.
또한, 본 고안은 상기 고정자(60)의 내주방향으로는 소정의 배치간격을 두고 냉각홀(110)이 형성됨으로서 상기 냉각팬(120)에 의해 모터하우징(40)내로 유입되는 공기가 상기 냉각홀(110)로 고르게 유입되어 고정자(60)가 신속하면서도 효율적으로 냉각되는 것이다.In addition, according to the present invention, since the cooling holes 110 are formed at predetermined intervals in the inner circumferential direction of the stator 60, the air introduced into the motor housing 40 by the cooling fan 120 is the cooling holes. The stator 60 is cooled evenly and efficiently by flowing into the 110.
본 고안은 고정자와 근접배치된 로우터의 선단에 냉각팬이 일체로 형성되고 또한 ,상기 고정자의 내주면에는 소정의 배치간격을 두고 냉각홀이 각각 형성됨으로서, 세탁기의 작동시 외전형전동기가 구동되게 되면 상기 외전형전동기에 장착되어진 로우터가 회전됨과 동시에 그 상부에 형성되어진 냉각핀이 동시에 정.역회전하게 되면서 외부의 공기를 모터하우징내로 신속하게 흡입 및 배출하여 외전형전동기를 효율적으로 냉각시켜줄수 있어, 외전형전동기가 과열되는 것을 미연에 방지하여 세탁기용 외전형전동기의 사용수명을 극대화 할 수가 있는 효과가 있는 것이다.According to the present invention, a cooling fan is integrally formed at the front end of the rotor disposed close to the stator, and cooling holes are formed at predetermined intervals on the inner circumferential surface of the stator, so that an external electric motor is driven when the washing machine is operated. As the rotor mounted on the abduction motor is rotated and the cooling fin formed on the upper part is rotated forward and backward at the same time, external air can be sucked in and discharged quickly into the motor housing to efficiently cool the abduction motor. Therefore, it is possible to maximize the service life of the abduction motor for a washing machine by preventing the abduction motor from overheating.
