Description

드럼세탁기의 댐퍼Drum Washer Damper

본 발명은 드럼세탁기에 관한 것으로서, 특히 진동을 억제하기 위하여 외조 일체에 부착되는 댐퍼의 기능을 향상시킴과 동시에 재료비를 절감시키기 위한 댐퍼구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum washing machine, and more particularly, to a damper structure for improving the function of a damper attached to an outer tubular body to suppress vibration and at the same time reducing material costs.

일반적인 드럼세탁기는 도 1 에 도시된 바와같이 스프링(5)에 의해 캐비넷(2)에 지지되는 외조(1)와, 상기 외조(1)의 진동을 억제하기 위한 댐퍼(7)와, 상기 외조(1)내의 내조(미도시)를 회전시키도록 풀리(8)를 통해 구동력을 전달하는 모터(6)와, 상기 모터(6)의 반대측에 부착되어 외조(1) 전체의 무게중심과 관성 질량 중심을 조절해주기 위한 발란스 웨이트(9)와, 캐비넷(2)의 전면에 위치하는 도어(4)와, 상기 도어(4)와 외조(1) 사이를 연결하는 연성 물질의 도어 개스킷(10)으로 이루어진다.A general drum washing machine is an outer tub 1 supported by a cabinet 2 by a spring 5 as shown in FIG. 1, a damper 7 for suppressing vibration of the outer tub 1, and the outer tub ( 1) a motor 6 for transmitting a driving force through the pulley 8 to rotate the inner tank (not shown), and attached to the opposite side of the motor 6, the center of gravity and the center of mass of the outer tank 1 It is composed of a balance weight (9) for adjusting the weight, a door (4) located in the front of the cabinet (2), and a door gasket (10) of a soft material connecting the door (4) and the outer tub (1) .

도면중 미설명 부호 3 은 구동 제어를 위한 컨트롤부를 나타낸다.In the figure, reference numeral 3 denotes a control unit for driving control.

이와같이 구성되는 드럼세탁기는 탈수진행시, 모터(6)로부터 벨트를 통해 풀리(8)로 전달되는 회전력에 의해 외조(1)내의 내조가 세탁물과 함께 회전을 하게되고, 그 원심력을 이용해 수분을 탈수시키게 된다. 이때 세탁물의 편심에 의해 발생하는 이상 진동이 외조(1) 전체로 확산되어, 그 전달력이 스프링(5)과 댐퍼(7)를 통하여 캐비넷(2)에 전달이 되고, 외조와 캐비넷의 진동은 소음으로 방사되며, 세탁기의 웍킹 현상을 발생시키게 된다.The drum washing machine configured as described above rotates the inner tank in the outer tub 1 together with the laundry by the rotational force transmitted from the motor 6 to the pulley 8 through the belt when dehydration proceeds, and dehydrates water using the centrifugal force. Let's go. At this time, the abnormal vibration caused by the eccentricity of the laundry spreads to the entire outer tank 1, and the transmission force is transmitted to the cabinet 2 through the spring 5 and the damper 7, and the vibration of the outer tank and the cabinet Radiated by the noise, it causes a walking phenomenon of the washing machine.

일반적으로 댐퍼(7)의 댐핑력이 크면 과도 상태의 진동은 잘 막아주지만, 정상 상태에서는 오히려 진동을 상대적으로 크게 한다. 그렇기에 댐핑력을 무한히 크게 할 수는 없으며, 결국 진동을 막기 위해 종래에는 시스템의 무게를 무겁게 하기 위한 발란스 웨이트(9)를 전면에 부착하거나, 전면과 측면에 동시에 부착하는 등의 방법을 사용하였다. 또한, 이렇게 무거워진 시스템을 보호하기 위한 캐비넷(2) 역시 강도를 위해 그 두께가 두꺼워지게 된다.In general, when the damping force of the damper 7 is large, the vibration of the transient state is well prevented, but in the normal state, the vibration is relatively large. Therefore, the damping force cannot be infinitely increased, and thus, in order to prevent vibration, conventionally, a method of attaching the balance weight 9 to the front or the front and the side at the same time has been used to weight the system. In addition, the cabinet 2 for protecting such a heavy system is also thickened for strength.

종래의 일반적인 댐퍼구조는 도 2 에 도시된 바와같이 컨넥터(15) 및 컨넥터가이드(14)가 양단에 구현되어 각각 외조(1)와 캐비넷(2)에 연결되며, 일측에는 댐핑실린더(11)가 형성되고, 반대측에는 댐핑피스톤(12)이 끝단에 마찰패드(13)를 부착시킨 상태로 있어서, 상기 마찰패드(13)와 댐핑실린더(11) 내부의 마찰에 의해 마찰 댐핑력을 생성시키게 되었다.In the conventional general damper structure, as shown in FIG. 2, the connector 15 and the connector guide 14 are implemented at both ends, respectively, and are connected to the outer tub 1 and the cabinet 2, respectively, and a damping cylinder 11 is provided at one side thereof. The damping piston 12 is formed on the opposite side with the friction pad 13 attached to the end thereof, thereby generating a friction damping force by friction between the friction pad 13 and the damping cylinder 11.

전술한 바와 같이 세탁기의 이상 진동을 막기 위해 시스템의 무게를 무겁게 하는 방법을 사용한다면, 재료비가 상승하고 시스템의 이동이 불편해 지게된다. 그리고 댐핑력을 크게 하면 동작시에 소음이 커지게 되는 문제점이 있다.As described above, if the weight of the system is used to prevent abnormal vibration of the washing machine, the material cost increases and the movement of the system becomes inconvenient. In addition, if the damping force is increased, there is a problem that the noise increases during operation.

또한, 도 2 의 댐퍼구조에서 댐핑실린더(11)를 구현하기 위해 전면이 스틸로 된 실린더를 만들기 위해서는 재료비가 상승하고, 생산 공정상 스틸판을 말아서 실린더를 만들게 되는데 그 외부에는 내측 실린더를 고정하기 위해 플라스틱과 같은 물질로 만든 가이드를 추가로 만들어야 하므로 댐핑실린더(11) 전체의 두께가 두꺼워져서 열방사가 용이하게 이루어지지 않게 된다. 그리고 강한 마찰력을 구현함으로써 세탁시의 운동만으로도 실린더(11)와 마찰패드(13)의 온도가 쉽게 상승하여 정작 큰 댐핑력을 요구하는 탈수 과도상태에서는 그 상승한 온도로 인해 구현시의 댐핑력보다 작은 댐핑력만을 생성하게 되는 등의 문제점이 있었다.In addition, in order to implement the damping cylinder 11 in the damper structure of FIG. 2, the material cost is increased to make the cylinder of steel on the front side, and the steel plate is rolled up in the production process to make the cylinder. In order to make a guide made of a material such as plastic in order to further increase the thickness of the damping cylinder 11 is not easy to heat radiation. In addition, by implementing a strong friction force, the temperature of the cylinder 11 and the friction pad 13 are easily increased only by the movement during washing, and in the dehydration transient state requiring a large damping force, the temperature is smaller than the damping force at the time of implementation. There was a problem such that only the damping force is generated.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 일측 커넥터부에 픽싱로드를 다수개 연결하고, 상기 픽싱로드의 끝단에는 패드스프링을 형성하며, 상기 패드스프링의 끝단에는 댐핑패드가 고정된 패드가이드를 형성하고, 상기 댐핑패드의 중심에는 끝단에 타측 커넥터부가 연결된 슬롯피스톤을 관통시켜 댐퍼를 구성함으로서, 댐퍼의 기능을 향상시킬 수 있도록 하는데 목적이 있다.The present invention is invented to solve the problems of the prior art as described above, and connecting a plurality of fixing rods on one side of the connector portion, the end of the fixing rod to form a pad spring, the end of the pad spring damping pad The pad guide has a fixed pad guide, and a damper is formed by penetrating a slot piston connected to the other connector portion at the end of the damping pad, thereby improving the function of the damper.

이하, 본 발명을 첨부도면을 참조하여 이하에서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명이 적용되는 드럼세탁기는 댐퍼구조를 제외한 전체적인 구성 및 동작상태는 종래기술과 동일하므로 그 이외의 구성에 대해서는 그 설명을 생략하기로 한다.Drum washing machine to which the present invention is applied, the overall configuration and operation state except the damper structure is the same as the prior art will be omitted for the other configurations.

도 3 은 본 발명의 제 1 실시예에 의한 댐퍼구조를 나타낸 것으로서, 컨넥터(25) 및 컨넥터 가이드(24)는 종래와 차이가 없으나 댐핑실린더 자체가 구현되어 있지 않고, 일측에는 픽싱로드(26)가 2개이상 장착되었으며, 끝단에는 패드스프링(27)이 형성되고, 상기 패드스프링(27)의 끝단에는 댐핑패드(29)를 잡아주고 있는 패드가이드(28)가 연결되어 있다. 여기에 구현된 댐핑패드(29)의 중심에는 끝단에 컨넥터(25)가 연결된 슬롯피스톤(20)이 관통되어 댐핑패드(29)와 슬롯피스톤(20) 사이의 마찰력으로 마찰 댐핑력을 생성시킨다.Figure 3 shows a damper structure according to the first embodiment of the present invention, the connector 25 and the connector guide 24 is not different from the prior art, but the damping cylinder itself is not implemented, the fixing rod 26 on one side Two or more are mounted, a pad spring 27 is formed at the end, and a pad guide 28 holding the damping pad 29 is connected to the end of the pad spring 27. In the center of the damping pad 29 implemented here, the slot piston 20 connected to the connector 25 is penetrated to generate a friction damping force by the friction force between the damping pad 29 and the slot piston 20.

이와같이 구성되는 본 발명 댐퍼의 특징 및 동작을 이하에서 살펴보기로 한다.Features and operations of the damper of the present invention configured as described above will be described below.

우선, 실린더를 없애고 픽싱로드(26) 만으로 외조를 지지를 하게 됨으로 재료비가 절감되며, 통풍이 잘되어 열방사가 수월하다. 그리고, 슬롯피스톤(20)은 그 자체가 핀의 역할을 하므로 열방사 효율이 더욱 향상된다. 그리고 패드스프링(27)으로 인해 정상상태와 같은 큰 변위에서는 댐핑력이 작동되어 2단계의 댐핑력을 구현할 수가 있게된다. 또한, 종방향의 운동 이외의 횡방향 운동에 대해서 스프링의 굽힘으로써 댐퍼 자체에 밴딩력을 적게 가하여 주므로, 그 내구성에서도 횔씬 유리하다고 볼 수 있다. 마찰력은 접촉 면적의 크기에 거의 영향을 받지 않으며 그로 인해 생성되는 댐핑력의 등가 댐핑 계수는 하기 [수학식 1]로 나타낼 수 있다.First of all, by removing the cylinder and supporting the outer tank with only the fixing rod 26, the material cost is reduced, and the ventilation is easy to facilitate heat radiation. In addition, since the slot piston 20 itself serves as a fin, the thermal radiation efficiency is further improved. In addition, due to the pad spring 27, the damping force is operated at a large displacement, such as a steady state, to realize a two-stage damping force. In addition, since the bending force is applied to the damper itself by bending the spring for lateral movements other than the longitudinal movements, it can be seen that the durability is much advantageous. The frictional force is hardly influenced by the size of the contact area, and the equivalent damping coefficient of the damping force generated thereby can be represented by the following [Equation 1].

[수학식 1][Equation 1]

(단, fn: 마찰력, X: 진폭, ω: 주파수, ψ: 원주율)(Where fn: frictional force, X: amplitude, ω: frequency, ψ: circumference)

상기 [수학식 1]에서 마찰력(fn)은 마찰계수와 수직항력의 곱으로 나타내어 지고, 마찰계수는 두 접촉면을 구성하는 물질과 표면처리에 의해서만 거의 그 값이 결정되어 지므로, 접촉면적이 작아져도 충분히 원하는 만큼의 마찰력을 생성할 수 있다는 것을 알 수가 있다.In [Equation 1], the friction force (fn) is expressed as the product of the friction coefficient and the vertical drag, and the friction coefficient is almost determined only by the material and the surface treatment constituting the two contact surfaces, even if the contact area is small It can be seen that enough friction can be generated as desired.

도 4 는 본 발명의 제 2 실시예에 의한 댐퍼구조를 나타낸 것으로서, (가)와 같이 슬롯피스톤(20)의 끝단을 자유롭게 두지 않고 제2댐핑패드(29')를 부착하여 댐핑패드의 원주면이 픽싱로드(26)와 마찰을 함으로써, 마찰력을 더욱 증가시킨 것이다. 또는 제1댐핑패드(29)의 마찰력보다 약한 마찰력을 생성시키는 댐핑패드를 두 개이상 사용하여 종래 기술에서의 댐퍼와 동일한 크기의 마찰력을 생성시키는 한편, 무리한 힘을 슬롯피스톤(20)에 집중시키지 않는 효과를 볼수도 있다.4 shows a damper structure according to the second embodiment of the present invention, and the circumferential surface of the damping pad is attached by attaching the second damping pad 29 'without leaving the end of the slot piston 20 freely as shown in (a). By friction with the fixing rod 26, the frictional force is further increased. Alternatively, by using two or more damping pads that generate frictional force that is weaker than the frictional force of the first damping pad 29 to generate frictional force of the same size as the damper in the prior art, the excessive force is not concentrated in the slot piston 20. You may see the effect.

도 4 의 (나)에 나타낸 제 3 실시예와 같이 패드스프링(27)과 연결된 픽싱로드(26)에 슬롯피스톤(20)이 관통되는 제3댐핑패드(29")를 고정시킴으로써 상기 제 2 실시예와 동일한 효과를 구현할 수 있게된다.The second embodiment is secured by fixing the third damping pad 29 "through which the slot piston 20 is penetrated to the fixing rod 26 connected to the pad spring 27 as shown in the third embodiment shown in FIG. The same effect as in the example can be realized.

도 5 는 본 발명의 제 4 실시예를 나타낸 것으로 커넥터부(24,25)와 슬롯피스톤(20) 연결부에 탄성력을 갖는 스프링(27')이 형성되어, 패드스프링(27)과 함께 작동되거나 패드스프링(27)을 대신할 수 있도록하여 댐핑패드(29)가 슬롯피스톤(20)에 대해 기울어져도 횡방향의 응력을 받지 않도록 한 것이다.FIG. 5 illustrates a fourth embodiment of the present invention, in which a spring 27 'having elasticity is formed at a connector portion 24 and 25 and a slot piston 20 connection, and is operated together with a pad spring 27 or a pad. The spring 27 can be replaced so that the damping pad 29 is not subjected to lateral stress even when the damping pad 29 is inclined with respect to the slot piston 20.

이상 설명한 바와같이 본 발명의 댐퍼구조는 탈수 초기시와 같은 과도진동을 억제시키는 한편, 정상 상태일 때 댐퍼에 의해 외조로부터 캐비넷으로의 전달력을 이상적으로 구현함으로써 댐핑력에 의해 생성되는 불필요한 소음을 저감할 수 있으며, 재료비의 절감효과와 함께 댐핑력에 영향을 주는 마찰열의 방사를 용이하게 하는 효과가 있다.As described above, the damper structure of the present invention suppresses excessive vibration as in the initial stage of dehydration, while ideally realizing the transfer force from the outer tank to the cabinet by the damper in the steady state, thereby eliminating unnecessary noise generated by the damping force. It can be reduced, and the effect of reducing the material cost and facilitates the radiation of frictional heat affecting the damping force.
