Description

세탁기 모터의 냉각팬 풀리Cooling fan pulley of washing machine motor

본 발명은 세탁기의 모터 축에 설치되는 냉각팬 풀리에 관한 것으로서, 더욱 상세하게는 벨트의 결합이 용이하게 될 수 있는 구조를 가지는 세탁기 모터의 냉각팬 풀리에 관한 것이다.The present invention relates to a cooling fan pulley installed on a motor shaft of a washing machine, and more particularly, to a cooling fan pulley of a washing machine motor having a structure in which a belt can be easily coupled.

일반적으로, 세탁기는 세탁겸 탈수조와 펄세이터로의 모터의 회전력 전달이 클러치에 의해 단속되어, 세탁모드시에는 세탁기 모터의 회전력은 세탁겸 탈수조에 전달되지 않는 한편 펄세이터만 좌,우방향으로 회전시키도록 펄세이터에만 전달되어 세탁물의 세탁을 수행하고, 탈수모드시에는 세탁겸 탈수조 및 펄세이터를 동일한 속도로 동일방향으로 회전시키도록 세탁겸 탈수조와 펄세이터에 전달되어, 세탁물의 탈수를 수행하게 된다.In general, the washing machine is intermittent by the clutch transmission of the rotational force of the motor to the washing and dehydration tank and the pulsator, in the washing mode, the rotational force of the washing machine motor is not transmitted to the washing and dehydration tank while only the pulsator rotates left and right It is delivered only to the pulsator to wash the laundry, and in the dehydration mode is delivered to the washing and dehydration tank and pulsator to rotate the washing and dehydration tank and the pulsator in the same direction at the same speed, to perform the dehydration of the laundry Done.

통상적으로, 세탁기의 모터에는 모터의 과열을 방지하기 위하여 세탁기 모터를 냉각시킴과 동시에 모터의 회전구동력을 벨트를 통해 클러치로 전달하기 위한 냉각팬 풀리가 설치되고, 이러한 세탁기 구동 벨트는 조립 라인에서 클러치와 냉각팬 풀리에 결합될 때, 통상의 벨트공급수단에 의해 자동으로 냉각팬 풀리와 클러치 풀리에 결합되게 된다.Typically, the motor of the washing machine is provided with a cooling fan pulley for cooling the washing machine motor to prevent the motor from overheating and at the same time transferring the rotational driving force of the motor to the clutch through the belt. When combined with the cooling fan pulley, it is automatically coupled to the cooling fan pulley and the clutch pulley by a conventional belt supply means.

도 1은 종래 세탁기 모터의 냉각팬 풀리(1)를 도시한 것으로서, 냉각팬 풀리(1)는 냉각팬 풀리(1)상부에 클러치(7)의 풀리(8)로 모터(6)의 구동력을 전달하기 위하여 벨트(5)가 결합되는 풀리부(2)가 형성되고, 이 풀리부(2)의 하부에는 다수개의 팬이 방사상으로 형성된 팬부(3)가 형성된다.FIG. 1 shows a cooling fan pulley 1 of a conventional washing machine motor. The cooling fan pulley 1 applies the driving force of the motor 6 to the pulley 8 of the clutch 7 on the cooling fan pulley 1. A pulley portion 2 to which the belt 5 is coupled is formed for transmission, and a fan portion 3 in which a plurality of fans are radially formed is formed under the pulley portion 2.

그러나, 이와같이 구성된 종래 세탁기 모터의 냉각팬 풀리(1)는, 풀리부(2)를 형성하기 위하여 풀리부(2)와 팬부(3)의 경계부에 일정한 각도로 꺾여져 있는 계단부(4)가 형성되어 있으므로, 냉각팬 풀리(1)에 대한 벨트(5)의 결합시, 벨트(5)가 풀리부(2)에 결합되지 않고, 도 1에 가상선으로 도시된 바와같이 풀리부(2)와 팬부(3)의 경계부의 단부(4)에 걸리게 되는 사례가 빈번하게 발생되어, 세탁겸 탈수조 또는 펄세이터의 정확한 회전 속도를 얻을 수 없게 된다는 문제점이 있었다.However, the cooling fan pulley 1 of the conventional washing machine motor configured as described above has a stepped portion 4 which is bent at a predetermined angle at the boundary between the pulley portion 2 and the fan portion 3 to form the pulley portion 2. Since it is formed, upon engagement of the belt 5 to the cooling fan pulley 1, the belt 5 is not coupled to the pulley portion 2, and the pulley portion 2 is shown as an imaginary line in FIG. 1. The case where the edge part 4 of the boundary part of the fan part 3 is caught frequently occurs, and there existed a problem that the exact rotation speed of a washing | cleaning and dehydration tank or a pulsator could not be obtained.

따라서, 본 발명의 목적은 상술한 바와 같은 종래의 문제점을 해결하기 위하여 창출된 것으로서, 벨트의 결합시 벨트가 풀리에 용이하게 결합되도록 풀리부와 팬부 사이의 경계부를 개선한 세탁기 모터의 냉각팬 풀리를 제공하는데 있다.Accordingly, an object of the present invention has been created to solve the above-mentioned conventional problems, the cooling fan pulley of the washing machine motor to improve the boundary between the pulley and the fan so that the belt is easily coupled to the pulley when the belt is coupled To provide.

상술한 바와같은 목적을 달성하기 위하여, 본 발명은, 모터의 축에 결합되며 상부에 벨트가 결합되는 풀리부가 형성되고, 하부에 팬부가 형성된 세탁기 모터의 냉각팬 풀리에 있어서,In order to achieve the object as described above, the present invention, in the cooling fan pulley of the washing machine motor is coupled to the shaft of the motor and a pulley is coupled to the belt is formed on the upper portion,

완만한 경사면을 가지는 벨트 가이드부가 상기 풀리부와 팬부의 경계부에 형성되어, 벨트가 냉각팬 풀리에 결합될 때, 벨트는 벨트 가이드부를 따라서 풀리부로 가이드되는 것을 특징으로 하는 세탁기 모터의 냉각팬 풀리를 제공한다.A belt guide portion having a gentle inclined surface is formed at the boundary between the pulley portion and the fan portion, and when the belt is coupled to the cooling fan pulley, the belt is guided to the pulley portion along the belt guide portion. to provide.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 세탁기 모터의 냉각팬 풀리의 단면도이다.2 is a cross-sectional view of the cooling fan pulley of the washing machine motor according to the present invention.

도 2를 참조하면, 본 발명에 따른 세탁기 모터의 냉각팬 풀리(10)는, 상부에 벨트(14)가 결합되는 풀리부(11)가 형성되고, 하부에는 다수개의 팬이 방사상으로 형성된 팬부(12)를 가진다.Referring to FIG. 2, the cooling fan pulley 10 of the washing machine motor according to the present invention has a pulley part 11 to which a belt 14 is coupled to an upper part, and a fan part having a plurality of fans radially formed at a lower part thereof ( 12)

본 발명에 따라서, 완만한 경사면을 가지는 벨트 가이드부(13)가 풀리부(11)와 팬부(12)의 경계부에 형성되어, 벨트(14)가 냉각팬 풀리(10)에 결합될 때, 벨트 가이드부(13)를 따라서 풀리부(11)로 가이드되어, 풀리부(11)와 자동적으로 결합된다.According to the present invention, a belt guide portion 13 having a gentle inclined surface is formed at the boundary between the pulley portion 11 and the fan portion 12, so that when the belt 14 is coupled to the cooling fan pulley 10, the belt Guided to the pulley portion 11 along the guide portion 13, it is automatically engaged with the pulley portion (11).

상기로부터 알 수 있는 바와 같이, 본 발명에 따른 세탁기 모터의 냉각팬 풀리(10)는, 풀리부(11)와 팬부(12)의 경계부에 벨트(14)의 결합을 가이드하는 벨트 가이드부(13)가 완만한 각도를 가지는 경사면으로 형성되어 있으므로, 냉각팬 풀리(10)에 대한 벨트(14)의 결합시에, 벨트(14)가 벨트 가이드부(13)를 따라서 풀리부(11)로 자동적으로 결합된다.As can be seen from the above, the cooling fan pulley 10 of the washing machine motor according to the present invention, the belt guide portion 13 for guiding the coupling of the belt 14 to the boundary portion of the pulley portion 11 and the fan portion 12. ) Is formed as an inclined surface having a gentle angle, so that upon engagement of the belt 14 to the cooling fan pulley 10, the belt 14 is automatically moved to the pulley portion 11 along the belt guide portion 13. Are combined.

상기로부터 알 수 있는 바와 같이, 종래의 냉각팬 풀리에서, 냉각팬 풀리에 대한 벨트의 결합시, 벨트가 계단부에 걸리는 것에 의하여 풀리에 정확하게 결합되지 않고 풀리부와 팬부의 경계부에 형성된 계단부에 걸리는 현상이 본 발명에 따른 세탁기의 냉각팬 풀리에 의하여 방지될 수 있다.As can be seen from the above, in the conventional cooling fan pulley, when the belt is coupled to the cooling fan pulley, the belt is not precisely coupled to the pulley by being caught in the stepped portion and is formed on the stepped portion formed at the boundary of the pulley portion and the fan portion. Hanging phenomenon can be prevented by the cooling fan pulley of the washing machine according to the present invention.

이상에서 설명한 바와같이 본 발명 세탁기 모터의 냉각팬 풀리에 의하면, 풀리부와 팬부의 경계부에 벨트를 냉각팬 풀리부의 풀리로 가이드하도록 완만한 경사면을 가지는 벨트 가이드부가 형성되어 있으므로, 냉각팬 풀리에 대한 벨트의 결합시, 벨트가 풀리부로 자동적으로 결합될 수 있어서, 세탁겸 탈수조 또는 펄세이터의 정확한 회전 속도를 얻을 수 있다.As described above, according to the cooling fan pulley of the washing machine motor of the present invention, a belt guide portion having a gentle inclined surface is formed at the boundary between the pulley portion and the fan portion to guide the belt to the pulley of the cooling fan pulley portion. When the belt is engaged, the belt can be automatically engaged with the pulley, so that the correct rotational speed of the wash and dewater bath or pulsator can be obtained.
