Description
본 발명은 드럼세탁기의 웨이트 및 스프링장치에 관한 것으로서, 특히 세탁기의 구동시 전체 구동부의 균형을 유지하고 유동을 방지하기 위한 세탁기의 진동저감장치에 관한 것이다.The present invention relates to a weight and a spring device of a drum washing machine, and more particularly, to a vibration reducing device of a washing machine for maintaining the balance of the entire drive unit during driving of the washing machine and preventing flow.
종래의 드럼세탁기는 도 1 에 도시된 바와같이 세탁시 세탁수로 일정높이까지 채워지고 외곽케이스(10)에 상부의 스프링(7)에 의해 지지되는 외조(1)와, 상기 외조(1)의 내측에 회전지지되는 드럼(2)과, 상기 드럼(2)과 구동축(3)을 연결하는 허브(4)와, 상기 구동축(3)을 구동시키도록 동력을 전달하는 모터(5)와, 상기 외조(1)의 전면에 설치되어 후면의 구동부 무게와 균형을 맞추기 위한 전면 웨이트(6)로 구성된다.Conventional drum washing machine as shown in Figure 1 when the washing is filled with the washing water to a certain height and the outer casing (1) supported by the upper spring (7) in the outer case 10, and the outer tub (1) of A drum (2) rotatably supported inside, a hub (4) connecting the drum (2) and a drive shaft (3), a motor (5) for transmitting power to drive the drive shaft (3), and Installed on the front of the outer tub (1) is composed of a front weight (6) to balance the weight of the driving unit of the rear.
도면중 미설명 부호 8은 스프링이 부착되는 스프링 브라켓을 나타낸다.In the figure, reference numeral 8 denotes a spring bracket to which a spring is attached.
상기와 같이 구성되는 종래 드럼세탁기의 동작을 설명하면 다음과 같다.Referring to the operation of the conventional drum washing machine configured as described above are as follows.
먼저 정해진 행정에 따라 외조(1)에 일정 수위까지 세탁수를 채우고 나면 모터(5)의 회전력을 드럼(2)에 전달함으로써 세탁이 시작되는데 이때의 세탁 메카니즘은 드럼(2)이 회전함에 따라 드럼 내부에 부착된 세탁날개(미도시)가 세탁물을 끌고 수면 밖으로 나와올라가다가 날개의 수직위치까지 회전하기 직전에 세탁물이 세탁물/세액 위로 자유낙하 하는 방식으로 세탁물에 기계력을 전달하여 세탁을 수행하고 이후 동일한 방법으로 헹굼을 하고 헹굼이 끝나면 드럼을 일방향으로 고속회전 시켜 탈수를 수행한다.First, after the washing water is filled in the outer tank 1 to a predetermined level according to the predetermined stroke, washing is started by transmitting the rotational force of the motor 5 to the drum 2. The washing mechanism at this time is a drum as the drum 2 rotates. The laundry wing (not shown) attached to the inside pulls the laundry out of the water surface and transfers the mechanical force to the laundry in such a manner that the laundry falls freely above the laundry / tax liquid just before it rotates to the vertical position of the wing, and then the washing is performed. Rinse in the same way, and after rinsing, spin the drum in one direction at high speed to perform dehydration.
이때, 외조(1)의 전면에 위치하는 전면웨이트(6)는 드럼(2)의 회전시 세탁물 등의 유동에 의해 무게중심이 후단으로 몰리지 않도록 전체적인 균형을 유지하는 역할을 하게된다.At this time, the front weight 6 located on the front of the outer tub 1 serves to maintain the overall balance so that the center of gravity is not driven to the rear end by the flow of laundry, etc. during the rotation of the drum (2).
그러나 종래의 전면웨이트(6) 구조를 살펴보면 전체 구조의 길이방향으로 많은 부피를 차지하여 세탁기 전체의 무게가 무거워 지고, 이로 인하여 제품의 가격이 상승하게 되는등 효율적인 측면에서 문제점이 있었다.However, looking at the structure of the conventional front weight (6) occupies a large volume in the longitudinal direction of the overall structure, the weight of the overall washing machine is heavy, thereby causing a problem in terms of efficiency, such as the price of the product rises.
또한 스프링(7)이 고정되는 스프링브라켓(8)의 경우 전체 구조를 중심으로 외조(1)면의 적당한 위치에 설정함으로 인하여 세탁기의 탈수모드시 불평형이 발생하기 쉽고 인해 내부 진동에 큰 영향을 주는 문제점이 있었다.In addition, the spring bracket (8) in which the spring (7) is fixed to set the proper position of the outer tank (1) surface around the entire structure due to the unbalance easily occurs in the dehydration mode of the washing machine, which greatly affects the internal vibration There was a problem.
본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 외조의 전면에 장착되는 웨이트를 외조의 상단과 하단에 각각 분할하여 장착시키고, 외조의 상단을 지지하는 스프링이 드럼의 체적중심으로부터 최단거리에 위치하도록 구성함으로서, 웨이트의 부피를 줄이면서 세탁기 전체의 진동을 개선하도록 하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, the weight is mounted on the front and bottom of the outer tub, respectively mounted to the upper and lower ends of the outer tub, the spring supporting the upper end of the tub is the volume center of the drum It is intended to improve the vibration of the entire washing machine while reducing the volume of the weight by configuring the shortest distance from the.

본 발명을 첨부도면인 도 3 및 도 4를 참조하여 이하에서 설명한다.The present invention will be described below with reference to FIGS. 3 and 4.
먼저, 일실시예에 의한 드럼세탁기의 구성을 살펴보면 도 3 에 도시된 바와같이 외곽케이스(110)의 내부에는 세탁시 세탁수가 담겨지는 외조(101)가 장착되고, 상기 외조(101)의 전면측 상면과 하면에 각각 분할된 상,하 웨이트(103,104)가 장착되며, 상기 외조(101)의 내부에는 모터(105)로부터 동력을 전달받는 드럼(102)이 회전 가능하도록 구성되고, 상기 외조(101)를 지지하는 스프링(107)은 드럼(102)의 체적 중심으로부터 최단거리에 위치하는 외조(101)면에 고정된다.First, looking at the configuration of the drum washing machine according to an embodiment, as shown in FIG. 3, the outer tub 101 in which the washing water is contained in the outer case 110 is mounted, and the front side of the outer tub 101 is mounted. The upper and lower weights, respectively, are divided into upper and lower weights 103 and 104. Inside the outer tub 101, a drum 102 receiving power from the motor 105 is rotatable, and the outer tub 101. Spring 107 is fixed to the surface of the outer tub 101 located at the shortest distance from the volume center of the drum 102.
도면중 미설명 부호 106 은 스프링(107)이 장착되는 스프링브라켓을 나타낸다.In the figure, reference numeral 106 denotes a spring bracket on which the spring 107 is mounted.
세탁기는 드럼(102)안에 세탁물이 투입되어 세탁, 헹굼 및 탈수가 진행되어 세탁이 이루어진다. 따라서 외조(101)를 지지하는 스프링(106)의 위치는 드럼(102)의 내부체적의 무게중심에 위치하는 것이 바람직하다.In the washing machine, laundry is introduced into the drum 102, and washing, rinsing, and dehydration are performed. Therefore, the position of the spring 106 supporting the outer tub 101 is preferably located at the center of gravity of the inner volume of the drum 102.
도 5 는 드럼의 체적도를 나타낸 것으로 원통형 드럼(102)의 길이를 L, 상면과 하면이 동일한 A 의 면적을 갖는다고 하였을 때, 드럼의 체적중심(C)은 길이의 중심인 L/2 되는 위치상의 원통면을 따라 형성된다.FIG. 5 shows a volume diagram of the drum. When the length of the cylindrical drum 102 is L and the upper and lower surfaces have the same area of A, the volume center C of the drum is L / 2, which is the center of the length. It is formed along the cylindrical surface in position.
본 발명은 상기 체적중심(C)이 드럼 중심으로부터 방사상으로 연장되며 만나는 외조(101)면상에 스프링의 고정위치인 스프링브라켓(106)을 설치하는 것으로 본 발명의 실시예에 의한 스프링(107)은 외조(101)의 좌우측에 각각 3개씩 위치하므로 중앙의 스프링을 드럼(102)의 체적중심(C)에 위치하도록 하고, 양 옆의 스프링은 각각 중앙스프링과 동일한 거리에 위치시켜 상기 구조체를 안정적으로 지지하도록 하였다.According to the present invention, the spring 107 according to the embodiment of the present invention installs a spring bracket 106, which is a fixed position of the spring, on the surface of the outer tub 101 where the volume center C extends radially from the drum center. Since each of the three in the left and right sides of the outer tub 101, the central spring is located in the center of the volume (C) of the drum 102, and the springs on both sides are located at the same distance as the central spring, respectively, to stably maintain the structure. Support was made.
그리고 종래의 전면 웨이트를 외조 전면에 배치하는 것과는 달리 본 발명의 웨이트(103,104)를 상,하 2개로 분할하여 외조(101)의 상면과 하면에 각각 배치하여 전체 구조의 길이방향 부피를 줄이면서 외곽케이스(110)와 외조(101)사이의 비사용공간을 이용함으로 세탁기의 용량을 증가시킬 수 있게된다.Unlike the conventional front weight on the outer tank front, the weight (103, 104) of the present invention is divided into two, the upper and lower, respectively disposed on the upper and lower surfaces of the outer tub 101, while reducing the longitudinal volume of the overall structure of the outer By using the unused space between the case 110 and the outer tub 101, it is possible to increase the capacity of the washing machine.
도 4 는 본 발명에 의한 웨이트(103,104)가 장착 정면도를 나타낸 것으로 드럼(102)의 외면과 같은 곡률로 웨이트가 형성되어 전체 구조체의 부피를 줄일 수 있도록 하였다. 이때, 웨이트의 무게와 형상은 전체 구동부의 무게중심이 스프링(107) 고정위치와 일치하도록 결정한다.4 is a front view showing mounting weights 103 and 104 according to the present invention, and the weight is formed with the same curvature as the outer surface of the drum 102 to reduce the volume of the entire structure. At this time, the weight and shape of the weight is determined so that the center of gravity of the entire drive unit and the spring 107 fixed position.
이와같이 스프링과 웨이트를 구성함으로 전체 구동부의 관성 주축의 값이 줄어들고 세탁 및 탈수 행정시 전체 세탁기 구조체에 미치는 진동이 개선될 수 있는 것이다.By constructing the spring and the weight as described above, the value of the inertia spindle of the entire drive unit can be reduced, and the vibration on the overall washing machine structure during washing and dehydration stroke can be improved.
이상 설명한 바와같이 본 발명의 웨이트 및 스프링구조는 세탁조의 구동시 불균형으로 인하여 발생되는 진동을 저감하여 안정적인 세탁 및 탈수행정이 이루어질 수 있도록 하며, 이로인한 드럼세탁기의 신뢰성을 향상시키는 효과를 가져올 수 있게된다.As described above, the weight and the spring structure of the present invention can reduce the vibration caused by the imbalance during the driving of the washing tank to achieve a stable washing and dehydration stroke, thereby resulting in an effect of improving the reliability of the drum washing machine. do.
