본 고안은 세탁조의 진동감쇠용 댐핑장치를 갖는 세탁기에 관한 것이다.The present invention relates to a washing machine having a damping device for damping vibration of a washing tank.
세타기에서는, 세탁조 내에 세탁물을 수용하여 세탁, 탈수 등을 행할 수 있도록 되어 있다. 이러한 세탁기가 세탁 및 탈수공정을 수행하는 경우에는 세탁조의 회전이나 세탁조 내부에 설치된 펄세이터의 회전 등에 의하여 진동이 발생하게 된다. 이 진동을 감쇠시키기 위해 종래의 세탁기에는 진동감쇠장치가 마련되어 있다.In the settagi, laundry, dehydration, and the like can be stored in a laundry tank. When the washing machine performs the washing and dehydration process, vibration may occur due to the rotation of the washing tank or the rotation of a pulsator installed in the washing tank. In order to damp this vibration, a conventional washing machine is provided with a vibration damping device.
제2도는 종래의 세탁기의 측단면도이다. 이 도면에서 도시된 바와 같이, 종래의 세탁기는 세탁기 전체의 외관을 구성하는 외부 케이싱(100)과, 외부케이싱(100) 내에 설치되어 있는 외조(101)와, 외조(101) 내에 설치되어 있는 세탁조(102)를 가지고 있다.2 is a side cross-sectional view of a conventional washing machine. As shown in this figure, a conventional washing machine includes an outer casing 100 constituting the entire appearance of the washing machine, an outer tub 101 installed in the outer casing 100, and a washing tub installed in the outer tub 101. Has 102.
외조(101)는 다수의 서스펜션(103)에 의해 외부케이싱(100) 내에 매달려 지지되어 있고, 외조(101)의 하부에는 구동모터(104) 및 샤프트조립체(105)가 설치되어 있다. 샤프트조립체(105)의 주위를 둘러싸는 새들(106)은 샤프트조립체(105)가 외조(101)에 견고히 부착되도록 지지한다. 구동모터(104)의 동력은 벨트(107)를 통해 샤프트조립체(105)에 전달되고, 샤프트조립체(105)는 샤프트를 통해 세탁조(102) 또는 세탁조(102) 내의 펄세이터(108)를 회전구동시킨다.The outer tub 101 is suspended and supported in the outer casing 100 by a plurality of suspensions 103, and a drive motor 104 and a shaft assembly 105 are provided below the outer tub 101. The saddle 106 surrounding the shaft assembly 105 supports the shaft assembly 105 to be firmly attached to the outer tub 101. Power of the drive motor 104 is transmitted to the shaft assembly 105 through the belt 107, the shaft assembly 105 drives the washing tank 102 or the pulsator 108 in the washing tank 102 through the shaft. Let's do it.
이러한 구조로 이루어진 세탁기에서는, 탈수행정시에 세탁조(102)가 고속으로 회전함에 따라 진동이 발생한다. 이러한 진동은 세탁물이 세탁조(102) 내에 고르게 분포하지 않고 한쪽으로 편중되어 분포할 경우에 발생하며, 특히 탈수행정의 초기 동작시에 세탁물의 편중이 심하여 많이 발생한다. 세탁조(102)의 진동이 있는 경우, 세탁조(102)는 샤프트조립체(105)에 의해 지지된 상태로 외조(101)내에 수용되어 있으므로, 그 진동은 외조(101)에 전달되어 외조(101)가 심하게 흔들리는 현상이 발생한다. 이러한 진동을 감쇠시키기 위해 외조(101)를 외부케이싱(100)의 내부에 매달아 지지하고 있는 서스펜션(103)은 진동을 감쇠시키는 장치의 역할을 겸하고 있다.In the washing machine having such a structure, vibration occurs as the washing tub 102 rotates at a high speed during the dehydration stroke. This vibration occurs when the laundry is not evenly distributed in the washing tank 102, but is unevenly distributed to one side, and in particular, the laundry is heavily biased during the initial operation of the dehydration stroke. When there is a vibration of the washing tub 102, since the washing tub 102 is accommodated in the outer tub 101 while being supported by the shaft assembly 105, the vibration is transmitted to the outer tub 101 so that the outer tub 101 is applied. Severe shaking occurs. Suspension 103 which suspends and supports the outer tub 101 inside the outer casing 100 to damp these vibrations also serves as a device for damping vibrations.
그러나, 세탁물의 편중이 심하여 진동이 매우 심할 경우에는 서스펜션(103) 만에 의해서는 진동이 감쇠되지 않아, 외조(101)가 외부케이싱(100)의 내벽면에 부딪히는 경우가 발생하기도 하며, 심한 경우 탈수행정 자체가 정지되기도 한다.However, when the vibration is very severe due to the heavy load of the laundry, the vibration is not attenuated by the suspension 103 alone, and the outer tub 101 may hit the inner wall of the outer casing 100, which may be severe. The dehydration administration itself may be suspended.
따라서, 본 고안의 목적은, 세탁 및 탈수 중에 발생하는 진동을 적절하게 감쇠할 수 있는 댐핑장치를 구비한 세탁기를 제공하는 것이다.It is therefore an object of the present invention to provide a washing machine with a damping device capable of appropriately damping vibrations generated during washing and dehydration.
상기 목적은, 본 고안에 따라, 외부케이싱 내에 수용되는 외조와, 외조 내에 회전가능하게 설치되어 세탁물을 수용하는 세탁조를 갖는 세탁기에 있어서, 외조의 하부에 설치되는 상부마찰판과, 상부마찰판과 마찰접촉하는 하부마찰판과, 하부마찰판을 상부마찰판에 대해 탄성적으로 상향부세하는 탄성부재를 포함하는 것을 특징으로 하는 세탁기에 의해 달성된다.According to the present invention, a washing machine having an outer tub accommodated in an outer casing, and a washing tub rotatably installed in the outer tub for accommodating laundry, the upper friction plate installed under the outer tub, and friction contact with the upper friction plate. It is achieved by a washing machine characterized in that it comprises a lower friction plate and an elastic member to elastically uplift the lower friction plate relative to the upper friction plate.
여기서, 상부마찰판과 하부마찰판의 접촉면은 상호 형상맞춤되는 구면으로 형성될 수 있다. 또한, 탄성부재로는 외부케이싱의 베이스에 고정되는 압축코일스프링을 채용하는 것이 바람직하다.Here, the contact surface of the upper friction plate and the lower friction plate may be formed as a spherical shape to be mutually matched. In addition, it is preferable to employ a compression coil spring fixed to the base of the outer casing as the elastic member.
상부마찰판과 하부마찰판중 적어도 하나느 적어도 마찰면이 고무, 폴리아미드, 폴리아세틸, 폴리프로필렌으로 이루어진 그룹 중에서 선택된 하나로 형성될 수 있고, 상부마찰판이 외조의 하부영역에 설치되어 샤프트조립체를 둘러싸는 새들에 고정되도록 하면 더욱 바람직하다.At least one of the upper friction plate and the lower friction plate may be formed of at least one friction surface selected from the group consisting of rubber, polyamide, polyacetyl, and polypropylene, and the upper friction plate is installed in the lower region of the outer shell to surround the shaft assembly. It is more preferable to be fixed to the.
이하에서 첨부도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 세탁기의 측단면도이다. 이 도면에서 볼 수 있는 바와 같이, 본 고안에 따른 세탁기는, 종래의 세탁기와 마찬가지로, 외관을 형성하는 외부케이싱(1)과, 외부케이싱(1) 내에 설치되어 있는 외조(2)와, 외조(2) 내에 설치되어 있는 세탁조(3)를 가지고 있다. 외조(2)는 다수의 서스펜션(9)에 의해 외부케이싱(1) 내부에 매달려 있고, 외조(2)의 하부에는 구동모터(4) 및 샤프트조립체(5)가 설치되어 있고, 샤프트조립체(5)는 새들(6)에 의해 둘러싸여 있다. 구동모터(4)의 동력은 벨트(7)를 통해 샤프트조립체(5)에 전달되고, 샤프트조립체(5)는 샤프트를 통해 세탁조(3) 또는 세탁조(3) 내에 설치되어 있는 펄세이터(8)를 회전구동시킨다. 세탁행정시에는 펄세이터(8)가 회전하여 세탁조(3) 내에 수용된 세탁물을 회전시키고, 탈수행정시에는 세탁조(3)을 회전시킨다. 세탁조(3)는 그 기능에 따라 탈수조라고도 불린다.1 is a side cross-sectional view of a washing machine according to the present invention. As can be seen from this figure, the washing machine according to the present invention, like the conventional washing machine, the outer casing 1 to form an appearance, the outer tub 2 provided in the outer casing 1, and the outer tub ( 2) has a washing tank (3) installed in. The outer tub 2 is suspended inside the outer casing 1 by a plurality of suspensions 9, and a drive motor 4 and a shaft assembly 5 are installed below the outer tub 2, and a shaft assembly 5 is provided. Is surrounded by birds 6. The power of the drive motor 4 is transmitted to the shaft assembly 5 via the belt 7, which shaft assembly 5 is installed in the washing tank 3 or in the washing tank 3 via the shaft. Rotate the The pulsator 8 rotates in the washing stroke to rotate the laundry contained in the washing tank 3, and rotates the washing tank 3 in the dehydrating stroke. The washing tank 3 is also called a dehydration tank according to the function.
새들(6)의 하부에는, 부분구면체로 형성된 상부마찰판(10)이 설치되어 있고, 그 하부에는 상부마찰판(10)과 형상맞춤하여 접촉하는 역시 부분구면체로 된 하부마찰판(11)이 설치되어 있다. 이들 상부 마찰판(10)과 하부마찰판(11)은 상호간의 내구적 마찰저항을 유지하기 위해, 고무, 폴리아미드, 폴리아세틸, 폴리프로필렌 등의 재료로 만들어지며, 경우에 따라서는 적어도 마찰면의 일부 혹은 일정두께가 이 들 재료로 형성될 수 있다. 이 하부마찰판(11)의 하부에는, 압축코일스프링(12)이 설치되어, 하부마찰판(11)을 외부케이싱(1)의 베이스로부터 상부마찰판(10)에 대해 탄성적으로 상향부세하도록 되어 있다.In the lower part of the saddle 6, an upper friction plate 10 formed of a partial spherical body is provided, and a lower friction plate 11, also made of a partial spherical body, in contact with the upper friction plate 10 in conformity with the upper friction plate 10 is provided. . These upper friction plates 10 and lower friction plates 11 are made of a material such as rubber, polyamide, polyacetyl, polypropylene, etc., in order to maintain the durable friction resistance between them, and in some cases at least part of the friction surface. Or a certain thickness can be formed from these materials. A compression coil spring 12 is provided below the lower friction plate 11 to elastically upwardly lower the friction plate 11 from the base of the outer casing 1 with respect to the upper friction plate 10.
이러한 구조에 의하여, 세탁기 운전 중, 특히 탈수시에, 세탁조(3)에 진동에 따라 외조(2)가 일체로 진동하게 되면, 외조(2)에 일체로 결합된 상부마찰판(10)을 압축코일스프링(12)에 의해 상향으로 탄성부세되는 하부마찰판(11)과 마찰접촉하여 그 진동을 감쇠시킨다.According to this structure, during operation of the washing machine, especially during dehydration, if the outer tub 2 vibrates integrally with the vibration in the washing tub 3, the upper friction plate 10 integrally coupled to the tub 2 is compressed by a coil. The vibration is attenuated by frictional contact with the lower friction plate 11 elastically biased upward by the spring 12.
이에 따라, 외조(2)를 탄성적으로 현수하고 있는 서스펜션(9)의 진동감쇠효과에 부가하여 상하부마찰판(10,11)간의 마찰에 의한 진동감쇠력이 세탁조(3) 및 외조(2)의 진동을 현저히 저감시키게 된다.Accordingly, in addition to the vibration damping effect of the suspension 9 that suspends the outer tub 2 elastically, the vibration damping force due to friction between the upper and lower friction plates 10 and 11 is caused to vibrate the washing tub 3 and the outer tub 2. Will be significantly reduced.
전술 및 도시한 예에서는 상하부마찰판이 부분구면체로 형성되어 있지만, 이 들을 단순한 판상체 예를 들오 원판체로 형성할 수도 있음은 물론이다.Although the upper and lower friction plates are formed as partial spherical bodies in the above-described and illustrated examples, of course, they may also be formed as simple plate-like examples, such as disks.
이상 설명한 바와 같이, 본 고안에 따르면, 세탁 및 탈수 중에 발생하는 진동을 적절하게 감쇠할 수 있는 댐핑장치를 구비한 세탁기가 제공된다.As described above, according to the present invention, a washing machine having a damping device capable of appropriately damping vibrations generated during washing and dehydration is provided.
