Description
본 고안은 세탁기의 구동풀리에 관한 것으로서, 보다 상세하게는 상기 세탁기의 저수조 하부에 설치되어 세탁조 및 펄세이터를 회전시키는 구동모터의 구동풀리구조에 관한 것이다.The present invention relates to a drive pulley of a washing machine, and more particularly, to a drive pulley structure of a drive motor installed at the bottom of the reservoir of the washing machine to rotate the washing tank and the pulsator.
일반적으로 세탁기는 도 1에 도시된 바와 같이 본체(10) 내부에 수조(20)가 매달려 설치되고 수조(20) 내부에 세탁조(30)가 구비된다. 또한 세탁조(30) 내부에 수류를 일으키는 펄세이터(40)가 설치되고 수조(20) 저면에 세탁조(30)와 펄세이터(40)를 선택적으로 구동시키는 동력절환부재(60)가 설치된다. 상기 동력절환부재(60)는 모터(50)로 구동되고 동력절환부재(60)의 세탁축(61a)이 펄세이터(40)와 연결되며 탈수축(미도시)이 세탁조(30)와 연결된다.In general, as shown in FIG. 1, the washing tank 20 is suspended from the main body 10 and the washing tank 30 is provided in the washing tank 20. In addition, a pulsator 40 for generating water flow in the washing tank 30 is installed, and a power switching member 60 for selectively driving the washing tank 30 and the pulsator 40 on the bottom of the water tank 20 is installed. The power switching member 60 is driven by a motor 50, the washing shaft 61a of the power switching member 60 is connected to the pulsator 40, the dehydration shaft (not shown) is connected to the washing tank 30. .
이처럼 구성된 세탁기는 세탁시 세탁조(30) 내부에 세탁물과 세탁수가 공급되고 모터(50)의 구동으로 동력절환부재(60)의 세탁축(61a)이 정역회전 되면 펄세이터(40)에 의해 수류가 일어나면서 빨래감이 비벼지며 소망하는 세탁이 진행된다.The washing machine configured as described above is supplied with laundry and water in the washing tub 30 during washing, and when the washing shaft 61a of the power switching member 60 is rotated forward and backward by the driving of the motor 50, the water flow is caused by the pulsator 40. As you wake up, the laundry is rubbed, and the desired laundry proceeds.
또한, 세탁 완료후 세탁수가 배수되고 상기 동력절환부재(60)의 탈수축에 의해 세탁조(30)가 고속으로 회전되면 그 원심력에 의해 세탁물이 탈수된다.In addition, after washing is completed, the washing water is drained and the laundry is dewatered by the centrifugal force when the washing tank 30 is rotated at a high speed by the dehydration of the power switching member 60.
상기 동력절환부재(60) 및 모터(50)의 축(51b)(61d)에 구동풀리(51)와 종동풀리(61c)가 각각 설치되고, 이들에는 밸트(52)가 결합되는데, 이 같은 상태에서 모터(50)가 회전되면 구동풀리(51)와 밸트(52)를 통하여 종동풀리(61)가 회전되고 이에 따라 동력절환부재(60)가 작동되어 세탁조(30) 또는 펄세이터(40)가 회전된다.The drive pulley 51 and the driven pulley 61c are respectively installed on the shaft 51b and 61d of the power switching member 60 and the motor 50, and a belt 52 is coupled thereto, and in this state. When the motor 50 is rotated in the driven pulley 51 and the driven pulley 61 through the belt 52 is rotated accordingly, the power switching member 60 is operated according to the washing tank 30 or pulsator 40 Is rotated.
여기에서, 상기 모터(5)의 구동풀리(51) 구조에 대해서 좀 더 상세히 설명하면, 제 2 도와 같이 원형의 몸통(51a)에 축(51b)이 삽입되는 축공(51')이 형성되고, 상기 몸통(51a)의 일측방에는 나사(미도시)가 체결되어 모터(50)의 축(51b)을 고정시키는 고정공(51)이 형성되며, 상기 몸통(51a)의 외주면에 풀리부(51a)가 형성됨과 아울러 상기 몸통(51a) 단부에 모터(50)가 회전할 때 발생되는 열을 냉각시켜 주는 냉각팬(51c)이 형성된다.Herein, the structure of the drive pulley 51 of the motor 5 will be described in more detail. As shown in FIG. 2, a shaft hole 51 'into which a shaft 51b is inserted into a circular body 51a is formed. On one side of the body 51a, a screw (not shown) is fastened to form a fixing hole 51 for fixing the shaft 51b of the motor 50, and a pulley part 51a on the outer circumferential surface of the body 51a. ) And a cooling fan 51c for cooling the heat generated when the motor 50 rotates at the end of the body 51a.
그런데, 종래의 구동풀리(51) 구조를 보면, 상기 냉각팬(51c)이 몸통(51a)과 일체로 형성됨에도 불구하고 몸통(51a)과 냉각팬(51c)의 결합부분이 극히 취약하여 상기 구동풀리(51)에 부하가 걸릴시에는 이 결합부위에 응력이 집중되어 크랙이 발생하게 되고, 이로 인하여 구동풀리(51) 전체를 교체하여야 하는 문제점이 있었다.However, in the conventional drive pulley 51 structure, although the cooling fan 51c is integrally formed with the body 51a, the coupling part of the body 51a and the cooling fan 51c is extremely fragile and thus the drive When the load is applied to the pulley 51, stress is concentrated on the coupling portion, and a crack occurs, which causes a problem that the entire driving pulley 51 needs to be replaced.
본 고안은 상기와 같은 문제점을 감안하여 창출한 것으로서, 상기 풀리부와 냉각팬을 응력이 집중되는 몸통과 분리시키므로서, 상기 풀리부와 냉각팬을 보호하는 한편, 몸통 파손으로 인한 교체비용을 절감할 수 있도록 한 세탁기의 구동풀리구조를 제공함에 그 목적이 있다.The present invention was created in view of the above problems, while separating the pulley part and the cooling fan from the body where the stress is concentrated, while protecting the pulley part and the cooling fan, and reducing the replacement cost due to the body damage. It is an object of the present invention to provide a drive pulley structure of a washing machine.

이상의 설명은 본 고안의 일 실시예에 불과하며 본 고안의 구성요지범위 내에서 얼마든지 그 변경이 가능하다.The above description is only one embodiment of the present invention and can be changed as many within the scope of the present invention.
상기와 같이 구성된 본 고안의 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the subject innovation configured as described above in detail.
상기 몸통(51a) 외주면에 냉각팬(51k)을 구비한 풀리부(51f)를 고정시키고, 상기 몸통(51a)의 축공(51b)에 모터(50)의 축(53)을 고정시킨 다음, 모터(50)를 회전시키게 되면, 상기 구동풀리(51)가 모터(50)에 의해 고속회전하면서 동력절환부재(60)를 회전시켜 세탁조(30)와 펄세이터(40)를 선택적으로 구동시키게 되는데, 이때 동력절환부재(60)의 종동풀리(61)와 밸트(52)로서 연결된 구동풀리(51)에 큰 부하가 걸리게 된다.The pulley portion 51f having the cooling fan 51k is fixed to the outer circumferential surface of the body 51a, and the shaft 53 of the motor 50 is fixed to the shaft hole 51b of the body 51a. When rotating the 50, the drive pulley 51 is rotated at a high speed by the motor 50 to rotate the power switching member 60 to selectively drive the washing tank 30 and the pulsator 40, At this time, a large load is applied to the driving pulley 51 connected as the driven pulley 61 and the belt 52 of the power switching member 60.
상기 구동풀리(51)에 전달되는 부하는 몸통(51a)에 국부적인 응력집중을 발생시키는데, 이 응력은 몸통(51a)과 풀리부(51f)의 경계에서 분산,소멸되거나 몸통(51a) 일부에 영향을 미치게 된다.The load transmitted to the drive pulley 51 generates a local stress concentration in the trunk 51a, which is dispersed or extinguished at the boundary between the trunk 51a and the pulley 51f, or is partially applied to the trunk 51a. Will be affected.
즉, 상기 몸통(51a)에 국부적인 응력집중이 발생하여 크랙이 생기게 되면 상기 몸통(51a)과 풀리부(51f)를 분리시킨 다음, 새로운 몸통(51a)을 풀리부(51f)에 고정시키면 된다.That is, when local stress concentration occurs in the trunk 51a and cracks are generated, the trunk 51a and the pulley 51f may be separated, and then the new trunk 51a may be fixed to the pulley 51f. .
본 고안은 상기 풀리부(51f)와 냉각팬(51k)을 응력이 집중되는 몸통(51a)과 분리시키므로서, 상기 풀리부(51f)와 냉각팬(51k)을 집중을력으로 부터 보호하는 한편, 상기 몸통(51a) 파손으로 인한 교체비용을 절감할 수 있도록 한 효과가 있다.The present invention separates the pulley part 51f and the cooling fan 51k from the trunk 51a where the stress is concentrated, thereby protecting the pulley part 51f and the cooling fan 51k from concentration. In addition, there is an effect to reduce the replacement cost due to damage to the body (51a).
