본 고안은 세탁기, 특히 전자동 세탁기의 진동감쇄장치에 대한 것으로서, 세탁조의 외면에 유체를 내장한 장치를 착설하여 유체의 점성과 관성을 이용 기존의 감쇄장치와 병행하여 진동을 효과적으로 감쇄시켜 줄 수 있도록 한 세탁기의 진동감쇄장치에 대한 것이다.The present invention relates to a vibration damping device of a washing machine, especially a fully automatic washing machine, to install a device with a built-in fluid on the outer surface of the washing tank to effectively reduce the vibration in parallel with the existing damping device using the viscosity and inertia of the fluid The vibration damping device of a washing machine.

종래에는 제4도에서 보는 바와 같이 세탁기(100)내에 세탁조(110)를 설치함에 있어서 세탁조(110)의 하부외면에 일체로 형성한 지지편(111)을 관통하게 끼운 지지봉(120)의 하단과 지지편(111) 사이에 완충스프링(220)을 개재시켜 이 스프링의 탄성을 이용하여 진동을 감쇄시켜 주도록 하였고, 탈수조는 그 상단부에 액체균형장치를 부설하여 진동을 감쇄시켜 주도록 하였다.Conventionally, as shown in FIG. 4, in installing the washing tub 110 in the washing machine 100, a lower end of the supporting rod 120 inserted through the supporting piece 111 integrally formed on the lower outer surface of the washing tub 110 and The damping spring 220 was interposed between the support pieces 111 to reduce the vibration by using the elasticity of the spring, and the dehydrating tank provided a liquid balance device at the upper end to reduce the vibration.

그러나, 세탁물의 편심에 의한 이상 진동이 발생할 경우에는 완충스프링(200)만으로는 세탁조(110) 및 탈수조에서 발생되는 진동을 효과적으로 감쇄시켜 주지 못하게 되어 세탁기의 구성 부품들의 수명단축은 물론 이상 소음이 발생되는 등 많은 결점이 있었다.However, when abnormal vibration occurs due to the eccentricity of the laundry, the buffer spring 200 alone does not effectively attenuate the vibration generated in the washing tank 110 and the dehydration tank, thereby shortening the lifespan of components of the washing machine and generating abnormal noise. There were many shortcomings such as being.

본 고안은 이러한 점들을 감안하여 고안한 것으로서 그 목적은 진동을 효과적으로 감쇄시켜 주는 진동감쇄장치를 제공하는 것이다.The present invention has been devised in view of these points, and an object thereof is to provide a vibration damping device that effectively attenuates vibration.

본 고안의 다른 목적은 이상 소음과 구성 부품들의 수명 단축을 방지하여 주는 진동감쇄장치를 제공함에 있다.Another object of the present invention is to provide a vibration damping device that prevents abnormal noise and shortening the life of the components.

본 고안은 이러한 목적들은 점성이 높고 비중이 큰 유체를 이용한 감쇄장치를 종래의 완충스프링과 병행하여 사용함으로써 달성하는데, 진동감쇄장치는 소정형태의 통체내에 적정량의 유체를 내장하고 밀폐시켜 구성하는 것으로 세탁조의 외면에 수개를 편심되지 않게 부착사용한다.The present invention achieves these objects by using a damping device using a highly viscous and high specific gravity fluid in parallel with a conventional shock spring. The vibration damping device is constructed by embedding and sealing an appropriate amount of fluid in a certain type of cylinder. We attach and use several on the outside of washing tub not to be eccentric.

진동이 발생되는 유체의 점성과 진동이 발생되는 유체의 점성과 관성에 의해 진동방향과 반대의 힘이 작용하여 진동을 감쇄시켜 주게 된다.Due to the viscosity of the fluid in which the vibration is generated and the inertia of the fluid in which the vibration is generated, a force opposite to the vibration direction acts to attenuate the vibration.

유체박스 내에는 1∼2개의 격판을 적정간격으로 수평착설하고 이들 격판에는 다수개의 유체유통공을 뚫어 설치한다.In the fluid box, one or two diaphragms are installed horizontally at appropriate intervals, and a plurality of fluid distribution holes are installed in these diaphragms.

따라서, 유체는 이들 유통공을 통해서만 이동하게 되어 급격한 이동이 방지 및 억제되며 이러한 과정에서 진동과 반대의 힘이 격판에 작용하게 되어 완충효과가 향상되게한 것이다.Therefore, the fluid is moved only through these flow holes to prevent and suppress the sudden movement and in this process the force opposite to the vibration acts on the diaphragm to improve the buffering effect.

이하, 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안 실시예에 의한 진동감쇄장치가 설치된 세탁기를 도시한 것이다.Figure 1 shows a washing machine equipped with a vibration damping device according to an embodiment of the present invention.

이 세탁기(10)의 내부에는 세탁조(11)가 지지봉(12)들에 의해 매달리는 형태로 설치되어 있고 세탁조(11)내에는 탈수조(13)가 설치되며, 이 탈수조내에 설치된 펄세이터(14)는 구동모우터(5)에 의해 회동된다.In the washing machine 10, a washing tank 11 is installed in a form of hanging by supporting rods 12, and a dehydrating tank 13 is installed in the washing tank 11, and a pulsator 14 installed in the dewatering tank. ) Is rotated by the drive motor (5).

세탁조(11)를 매달아주는 지지봉(12)들의 하단부는 세탁조(11)의 외면 하단부에 돌출시킨 지지편(101)들을 관통하게 결합함과 동시에 완충스프링(20)들을 개재시켜 세탁시에 발생되는 세탁조(11)의 진동을 완충시켜 주도록 하며, 탈수조(13)의 상단부에는 액체균형장치(30)를 착설하여 탈수조(13)의 균형을 잡아주도록 구성된다.The lower end of the support rods 12 that suspend the washing tank 11 are coupled to penetrate the support pieces 101 protruding to the lower end of the outer surface of the washing tank 11, and at the same time, the washing tank generated by washing through the buffer springs 20. The vibration of the (11) is to be buffered, and the liquid balance device 30 is installed at the upper end of the dehydration tank 13 so as to balance the dehydration tank 13.

이렇게 구성되는 세탁기(10)의 세탁조(11)외면 하부측에 진동감쇄장치가 설치된다.The vibration damping device is installed at the lower side of the outer surface of the washing tank 11 configured as described above.

제2도 및 제3도에는 본 고안 진동감쇄장치가 상세히 도시되어 있다. 이 진동감쇄장치는 밀폐되는 통체(30)내에 적정량의 점성을 유체(31)를 내장시켜 구성한다.2 and 3 show the vibration damping device of the present invention in detail. This vibration damping device is constructed by incorporating an appropriate amount of viscous fluid 31 into the sealed cylinder 30.

통체(30)내에는 적정간격으로 격판(32)(32')들을 수평착설하여 통체(30)내부가 서로 통하는 수개의 격실(310)로 구획되게 한다.In the cylinder 30, the diaphragms 32 and 32 'are horizontally mounted at appropriate intervals so that the interior of the cylinder 30 is divided into several compartments 310 communicating with each other.

이들 격판(32)(32')에는 다수개의 유체 유통공(321)들이 구비되어 있다.These diaphragms 32 and 32 ′ are provided with a plurality of fluid distribution holes 321.

따라서, 진동이 발생되면 유체(31)가 유통되는데, 이때 유체는 점성 및 관성에 의해 격판(32)(32')들에 진동방향과 반대의 힘을 가하게 되고, 또 격판(32)(32')들에 의해 급격한 유동이 제어됨과 동시에 유체유통공(321)들을 통해서만 다른 격실(310)로 이동하게 되게 함으로써, 이러한 과정에서 완충작용이 수행되게 구성한 것이다.Accordingly, when vibration occurs, the fluid 31 flows, in which the fluid exerts a force opposite to the vibration direction on the diaphragms 32 and 32 'by viscous and inertia, and the diaphragms 32 and 32'. By controlling the rapid flow by the) at the same time to move to the other compartment 310 only through the fluid distribution holes 321, it is configured to perform a buffer in this process.

통체(30)의 외면에는 세탁조(11)에 부착시 이용토록 수개의 고정편(311)들이 구비되어 있다.The outer surface of the cylinder 30 is provided with several fixing pieces 311 to be used when attached to the washing tank (11).

이와 같이 구성되는 본 고안 진동감쇄장치는 세탁조(11)의 외면 소정위치에 수개를 편심되지 않게 부착시켜 주면 된다.The vibration damping device of the present invention configured as described above may be attached to a predetermined position on the outer surface of the washing tank 11 so as not to be eccentric.

세탁시, 진동이 발생되게 완충스프링(20)들에 의해 서로 진동이 감쇄되지만 특히, 탈수시 세탁물의 편심에 의해 발생되는 상,하진동은 진동감쇄장치의 통체(30)에 전달되어 이 통체내의 유체(31)를 유통시켜 주게 되는데, 이렇게 되면 유체(31)는 점성과 관성에 의해 격판(32)(32')에 진동방향과 반대의 힘을 작용시켜 주게되어 상,하진동을 효과적으로 감쇄시켜 준다.When washing, vibrations are attenuated by each other by the shock absorbing springs 20 so as to generate vibrations. In particular, the upper and lower vibrations generated by the eccentricity of the laundry during dehydration are transmitted to the cylinder 30 of the vibration damping device. In this case, the fluid 31 is circulated. The fluid 31 causes the diaphragm and inertia to act on the diaphragms 32 and 32 'in the opposite direction to the vibration direction, thereby effectively attenuating the up and down vibrations. Let it be.

따라서, 본 고안은 이상 진동 및 소음을 효과적으로 감쇄시켜 주고, 이에 따라 구성 물론 세탁기 자체의 수명을 연장시켜 주는등의 효과도 얻을 수 있다.Therefore, the present invention effectively attenuates abnormal vibrations and noises, and thus it is possible to obtain an effect such as extending the life of the washing machine itself as well as the configuration.
