본 발명은 세탁기 도어 힌지구조, 특히 세탁기의 도어를 서행개폐할 수 있도록 한 세탁기 도어 힌지구조에 관한 것이다.The present invention relates to a washing machine door hinge structure, in particular a washing machine door hinge structure that allows the door of the washing machine to open and close slowly.

종래 기술의 세탁기 도어는 도어의 후면에 비틀림 스프링을 장착하여 도어가 일정각도 이상 열리면 상기 스프링의 힘으로 완전개방되고, 도어를 닫을 때에도 도어가 일정각도 이상 닫히면 상기 스프링의 힘으로 완전폐쇄되도록 구성되어 있다. 그러나 이와 같은 종래 기술의 세탁기 도어는 도어의 개방시와 폐쇄시에 도어와 세탁기 상부커버 사이의 충격을 방지할 수 있는 어떠한 구조도 구성되어 있지 않으므로 세탁기 사용자가 조심스럽게 도어를 열고 닫는 방법 외에는 충격을 방지하는 방법이 없었다.The washing machine door of the prior art is equipped with a torsion spring on the rear of the door is completely opened by the force of the spring when the door is opened more than a certain angle, and is configured to be completely closed by the force of the spring when the door is closed by a certain angle even when the door is closed. have. However, since the conventional washing machine door does not have any structure that can prevent the impact between the door and the upper cover of the washing machine at the time of opening and closing of the door, the washing machine user is not shocked except by opening and closing the door carefully. There was no way to prevent it.

따라서, 본 발명의 목적은 세탁기의 도어 개폐시에 도어와 세탁기 상부커버 사이의 충격을 방지하기 위해 도어를 서행으로 열고 닫을 수 있도록 한 세탁기 도어 힌지구조를 제공하는 것이다.Accordingly, an object of the present invention is to provide a washing machine door hinge structure that allows the door to be opened and closed in a slow way to prevent an impact between the door and the washing machine upper cover when opening and closing the door of the washing machine.

위와 같은 목적을 달성하기 위해 본 고안에, 도어의 힌지축에 고정 소기어; 상기 도어의 내부에 장착되고, 상기 소기어에 맞물리도록 구성됨으로써 상기 도어의 개폐시에 상기 소기어의 외주면을 따라 운동되도록 구성되어 있으며, 상기 도어의 개방시에 탄성력을 발휘함으로서 도어를 연직위치로 완전개방시킬 수 있는 스프링을 구비하는 대기어를 포함하는 것을 특징으로 하는 세탁기 도어 힌지구조를 제공한다.In the present invention to achieve the above object, a small gear fixed to the hinge shaft of the door; It is mounted inside the door and is configured to engage the small gear, and is configured to move along the outer circumferential surface of the small gear when the door is opened and closed. The door is moved to a vertical position by exerting an elastic force when the door is opened. Washing machine door hinge structure comprising a standby gear having a spring that can be fully opened.

이하, 첨부한 도면을 참고하여 본 고안의 일실시예에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

제1도는 본 발명의 일실시예에 따른 세탁기 도어 힌지구조의 측단면도, 제2도는 제1도의 평단면도이다.1 is a side cross-sectional view of a washing machine door hinge structure according to an embodiment of the present invention, Figure 2 is a plan cross-sectional view of FIG.

도면에 도시되어 있는 바와 같이, 본 발명의 세탁기 힌지구조는 도어(20)의 힌지축(11a)에 고정되어 있는 소기어(11)와 이 소기어(11)의 외주면에 따라 이동가능하게 구성된 대기어(12)를 포함한다.As shown in the figure, the washing machine hinge structure of the present invention is configured to be movable along the small gear 11 fixed to the hinge shaft 11a of the door 20 and the outer circumferential surface of the small gear 11. Gear 12.

상기 소기어(11)는 세탁기의 상부커버(21)와 도어(20) 사이에 장착된 힌지축(11a)에 고정되어 운동이 불가능하게 장착되어 있다.The small gear 11 is fixed to the hinge shaft 11a mounted between the upper cover 21 and the door 20 of the washing machine so that the small gear 11 is impossible to move.

또한, 상기 대기어(12)는, 제1도에 잘 도시되어 있는 바와 같이, 상기 도어(20)의 개폐시에 상기 소기어(11)의 외주면을 따라 이동가능하게 장착되어 있다. 또한, 상기 대기어(12)에는 상기 도어(20)의 개방시에 탄성력을 발휘함으로써 도어(20)를 연직위치(제1도의 일점쇄선)로 완전 개방시킬 수 있는 스프링(13)이 장착되어 있다. 또한 상기 도어(20)의 폐쇄상태에서 상기 스프링(13)이 긴장상태를 유지하고, 상기 도어(20)의 개방상태에서는 상기 스프링(13)이 이완상태를 유지하도록 되어 있다.Further, as shown in FIG. 1, the standby gear 12 is movably mounted along the outer circumferential surface of the small gear 11 when the door 20 is opened or closed. In addition, the air gear 12 is equipped with a spring 13 capable of completely opening the door 20 to the vertical position (one dashed line in FIG. 1) by exerting an elastic force when the door 20 is opened. . In addition, the spring 13 maintains the tension state in the closed state of the door 20, and the spring 13 maintains the relaxed state in the open state of the door 20.

이하, 본 발명의 작용에 대해 설명한다.Hereinafter, the operation of the present invention will be described.

먼저, 제1도의 실선으로 도시한 도어(20)의 폐쇄상태로부터 가상선으로 도시한 개방상태를 향해 도어(20)를 개방시키게 되면 도어(20)내에 장착되어 있는 대기어(12)가 도어의 힌지축(11a)에 고정되어 있는 소기어(11)의 외주면을 타고 상승이동하게 된다. 이때, 상기 스프링(13)은 긴장상태에서 비긴장상태로 천이하게 되어 도어는 서서히 개방될 수 있다.First, when the door 20 is opened from the closed state of the door 20 shown by the solid line of FIG. 1 toward the open state shown by the imaginary line, the standby gear 12 mounted in the door 20 is opened. Ascending movement is performed on the outer circumferential surface of the small gear 11 fixed to the hinge shaft 11a. At this time, the spring 13 is transitioned from the tension state to the non-tension state so that the door can be gradually opened.

도어(20)의 페쇄시에는 위의 과정과 반대과정이 되풀이 된다. 즉, 스프링(13)은 비긴장상태에서 긴장상태로 천이하게 되므로 도어(20)는 서서히 폐쇄될 수 있다.When the door 20 is closed, the above process and the reverse process are repeated. That is, since the spring 13 transitions from the non-tension state to the tension state, the door 20 may be closed slowly.

이상과 같은 본 발명의 도어 힌지구조에 의하면, 세탁기 사용자가 세탁기의 도어를 열고 닫을 때 특별한 주의를 기울이지 않더라도 도어가 충격적으로 열고 닫히는 일은 발생하지 않게 된다. 따라서, 세탁기 도어의 수명을 연장시켜 줄 뿐만 아니라 세탁기 사용이 편리해지는 효과가 있다.According to the door hinge structure of the present invention as described above, even if the washing machine user does not pay special attention when opening and closing the door of the washing machine, the door is not shocked to open and close. Therefore, not only the life of the washing machine door is extended, but also the use of the washing machine is convenient.
