본 발명은 자기부상수단을 이용한 세탁기용 소음 및 진동 감쇠장치에 관한 것이다.The present invention relates to a noise and vibration damping device for a washing machine using a magnetic levitation means.
일반적으로 산업기기 및 가전제품의 소음 및 진동은 환경공해의 요소로 취급될 정도로 현대사회의 환경문제로 대두되고 있으며 이를 감쇠하기 위한 장치로서 여러 장치들이 제품에 적용되고 있는 실정이다.In general, the noise and vibration of industrial equipment and home appliances are emerging as environmental problems in the modern society so that they can be treated as an element of environmental pollution, and as a device for attenuating them, various devices have been applied to products.
그러나 소음 및 진동 자체가 제품의 구동시에, 특히 모터를 사용하는 제품에 있어서는 필연적으로 발생되므로 이를 근원적으로 소멸시키는 것은 불가능하여 이를 감쇠시키기 위해 많은 노력을 하고 있다.However, since noise and vibration itself are inevitably generated when the product is driven, especially in a product using a motor, it is impossible to eliminate them in principle, and many efforts are made to attenuate them.
제1도는 종래 세탁기의 단면도를 간단히 나타낸 것으로 세탁시에 발생하는 모터(4)의 진동과 펄스에타(10)의 회전에 진동이 터브(7)에 전달되고, 탈수시에는 스핀바스켓(8)과 모터(4)의 진동이 터브(7)에 전달되어 터브지지대(2)를 따라 외함부(1)에 전달된다. 이를 감쇠시키시 위하여 터브지지대(2)와의 연장선상에 스프링코일(3)을 설치함으로써 터브(7)에 전달되는 진동을 1차적으로 감쇠시키고 고무레그(5)를 외함부(1) 아래쪽에 둠으로써 외함부(1)로 전달된 진동을 감쇠시키고 있다.1 is a simplified cross-sectional view of a conventional washing machine. Vibration is transmitted to the tub 7 by vibration of the motor 4 and rotation of the pulse eta 10 generated during washing, and spin basket 8 when dewatering. And vibrations of the motor 4 are transmitted to the tub 7 and transmitted to the enclosure 1 along the tub support 2. In order to attenuate this, by installing the spring coil 3 on the extension line with the tub support 2, the vibration transmitted to the tub 7 is primarily attenuated and the rubber leg 5 is placed below the enclosure 1. The vibration transmitted to the enclosure 1 is damped.
그러나 스프링코일(3)의 감쇠능력이 낮아서 외함부(1)로 진동이 전달되므로 고무레그(5)로 2차 감쇠를 시켜도 진동으로 인해 큰 소음이 발생하게 된다. 또한 터브지지대(2)는 터브(7)의 하중과 스프링코일(3)의 스프링의 힘까지 견디어야 하므로 응력은 커지게 된다.However, since the damping ability of the spring coil 3 is low, vibration is transmitted to the enclosure 1, and even though the second damping is performed with the rubber legs 5, a large noise is generated due to the vibration. In addition, since the tub support 2 must withstand the load of the tub 7 and the force of the spring of the spring coil 3, the stress is increased.
따라서 최근에는 공기스프링과 공기댐퍼를 이용하여 감쇠효율을 높이는 개선된 소음 및 진동 감쇠장치가 적용되고 있다.Therefore, in recent years, improved noise and vibration damping devices have been applied to increase damping efficiency by using air springs and air dampers.
본 발명은 이와 같은 소음 및 진동문제를 개선하기 위하여 창안된 것으로 소음 및 진동의 감쇠효율을 기존의 것보다 현저히 개선할 수 있는 세탁기용 소음 및 진동 감쇠장치를 제공함을 그 목적으로 한다.The present invention was devised to improve such noise and vibration problems, and an object of the present invention is to provide a noise and vibration damping device for a washing machine that can significantly improve the damping efficiency of noise and vibration than the conventional one.
상기 목적을 달성하기 위하여 본 발명은 외함부와, 상기 외함부의 내부에 위치되며 소음 및 진동원이 설치되는 터브와, 상기 외함부에 대해 상기 터브를 지지하는 터브지지대를 포함하는 세탁기에 설치되어 상기 소음 미 진동원으로부터 상기 터브에 전달되어 터브지지대를 따라 외함부에 전달되는 소음 및 진동의 전달을 감쇠시키는 소음 및 진동 감쇠장치에 있어서, 상기 터브지지대의 끝에 설치된 상마그네트와; 상기 상마그네트 하부의 상기 외함부에 상기 상마그네트와 동일한 극성이 마주하도록 설치된 하마그네트; 를 포함하여, 상기 상, 하마그네트 사이의 반발력에 의해 상기 터브 및 터브지지대가 자기 부상되어 소음 및 진동원으로부터 외함부로 전달되는 소음 및 진동을 감쇠시키도록 된 것을 특징으로 한다.In order to achieve the above object, the present invention is installed in a washing machine including an enclosure, a tub positioned inside the enclosure and installed with a noise and vibration source, and a tub support for supporting the tub against the enclosure. A noise and vibration damping device for attenuating transmission of noise and vibration transmitted from the noise vibration source to the tub and transmitted to the enclosure along the tub support, comprising: an upper magnet installed at the end of the tub support; Hamagnets installed so that the same polarity as the upper magnets facing the outer enclosure portion of the lower magnets; Including, the tub and the tub support by magnetic repulsion by the repulsive force between the upper, the bottom magnet is characterized in that to attenuate the noise and vibration transmitted from the noise and vibration source to the enclosure.
이하 첨부된 도면들을 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 발명에서는 소음 및 진동문제가 제품의 성능과 깊은 관계를 갖고 있는 세탁기를 실시예로서 본 발명을 설명하기로 한다.In the present invention, the present invention will be described by way of example of a washing machine in which noise and vibration problems have a close relationship with the performance of a product.
제2도는 본 발명의 실시예에 따른 소음 및 진동장치가 적용된 세탁기를 도시한 것이다.2 shows a washing machine to which a sound and vibration device according to an embodiment of the present invention is applied.
본 발명은 터브지지대(2)의 끝에 상마그네트(12)를 설치하고 상기 상마그네트(12) 하부의 외함부에 상기 상마그네트(12)와 동일한 극성이 마주하도록 하마그네트(13)를 설치하여 상기 두 마그네트(12, 13) 사이에 반발력을 갖도록 한다. 이러한 상기 마그네트(12, 13)는 1차 소음 및 진동 감쇠수단이 되며, 2차 소음 및 진동 감쇠수단으로서 고무레그(5)가 그 하부에 설치된다.In the present invention, the upper magnet 12 is installed at the end of the tub support 2, and the lower magnet 13 is installed at the lower portion of the upper magnet 12 so as to face the same polarity as the upper magnet 12. It has a repulsive force between the two magnets (12, 13). The magnets 12 and 13 serve as primary noise and vibration damping means, and rubber legs 5 are installed below the secondary noise and vibration damping means.
상, 하 마그네트(12, 13)는 같은 극성으로 대향되어 있으므로 반발력을 갖고 이 반발력에 의해 터브(7) 및 터브지지대(2)가 자기 부상되어 떠받쳐지게 된다. 따라서, 자기부상수단으로서 상기 상, 하 마그네트(12, 13)는 자기서스펜션(16)을 이루며, 이러한 자기서스펜션(16)은 소음 및 진동원(스핀바스켓(8), 모터(4)등)으로부터 외함부(1)로 전달되는 소음 및 진동을 감쇠시키게 된다.Since the upper and lower magnets 12 and 13 face each other with the same polarity, they have a repulsive force and the tub 7 and the tub support 2 are magnetically lifted and held by the repulsive force. Thus, the upper and lower magnets 12, 13 as magnetic levitation means constitute a magnetic suspension 16, which is susceptible to noise and vibration sources (spin basket 8, motor 4, etc.). The noise and vibration transmitted to the enclosure 1 is attenuated.
세탁 및 탈수시에 모터(4), 크러치(6), 스핀바스켓(8)등의 진동이 터브(7)를 따라 자기서스펜션(16)은 및 레그(5)에 전달되는데 자기서스펜션(16)에 의해 1차 감쇠되고 고무레그(5)에 의해 2차 감쇠되므로 외함부(1)에 전달되는 소음 및 진동의 감쇠율을 극대화하여 준다.During washing and dehydration, vibrations of the motor 4, the clutch 6, the spin basket 8, and the like are transmitted along the tub 7 to the magnetic suspension 16 and the leg 5, which are transferred to the magnetic suspension 16. By primary attenuation by the rubber leg (5) secondary attenuation maximizes the damping rate of the noise and vibration transmitted to the enclosure (1).
상기와 같은 본 발명에 사용되는 상, 하 마그네트(12, 13)로는 영구자석 및 전자석이 이용될 수 있는데, 상, 하마그네트(12, 13)의 감자가 예상되는 자기회로의 경우에는 마그네트의 감자를 없애주는 상, 하요크(11, 14)를 상기 상마그네트(12)의 상부와 상기 하마그네트(12)의 하부에 각각 설치한다.As the upper and lower magnets 12 and 13 used in the present invention as described above, permanent magnets and electromagnets may be used. In the case of magnetic circuits in which upper and lower magnets 12 and 13 are expected, the magnets of the magnets may be used. Removing the upper and lower yoke (11, 14) is installed in the upper portion of the upper magnet 12 and the lower magnet 12, respectively.
제3도는 제2도의 세탁기에 적용된 본 발명에 따른 자기서스펜션(16) 및 요크(11, 14)를 도시한 것으로 터브(7)를 둘러싼 커다란 원형의 자기 서스펜션(16)을 나타낸 것이다.3 shows a magnetic suspension 16 and yoke 11, 14 according to the invention applied to the washing machine of FIG. 2, showing a large circular magnetic suspension 16 surrounding the tub 7.
이와 같은 자기 서스펜션(16)을 이용한 경우에 종래의 코일스프링, 공기댐퍼, 공기스프링에 의한 소음 및 진동 감소수단에 대응하여, 본 발명의 자기 서스펜션(16)에 의한 소음 및 진동 감소수단의 소음 및 진동감쇠효과를 측정하기 위하여 일조형(Single Pulsator Type) 6.5kg용량의 세탁기로 세탁 및 탈수시의 소음 및 진동을 측정하였다. 진동은 세탁기 외함부에 가속도 센서를 놓고 진폭을 측정하였으며, 소음은 세탁기 정면으로부터 1m떨어진 곳에서 측정하였는데 그 결과는 아래의 표 1와 같다.When the magnetic suspension 16 is used as described above, the noise and vibration reduction means of the magnetic suspension 16 of the present invention correspond to the noise and vibration reduction means of the coil spring, the air damper, and the air spring. To measure the vibration damping effect, noise and vibration during washing and dehydration were measured in a washing machine with a capacity of 6.5 kg of a single pulsator type. The vibration was measured by placing the acceleration sensor in the washing machine enclosure and the noise was measured 1m away from the front of the washing machine. The results are shown in Table 1 below.
상기한 바와 같이 본 발명의 자기 부상에 의한 소음 및 진동 감쇠장치를 이용하게 되면 소음 및 진동이 현저히 줄어들어 정음화된 세탁기를 제공할 수 있는 이점이 있다.As described above, when the noise and vibration damping device caused by the magnetic levitation of the present invention is used, the noise and vibration are remarkably reduced, thereby providing a silent washing machine.
