Description
본 고안은 세탁기의 완충장치에 관한 것으로서, 더욱 상세하게는 스프링을 승강시켜 빨래감의 중량에 따라 스프링의 유효권수가 조절되도록 함으로서, 세탁 또는 탈수시 진동이 최소화 되도록한 세탁기의 완충장치에 관한 것이다.The present invention relates to a shock absorber of a washing machine, and more particularly to a shock absorber of the washing machine to minimize the vibration during washing or dehydration by adjusting the effective number of the spring according to the weight of the laundry by lifting the spring.
일반적으로 세탁기는 제1도에 도시된 바와 같이 본체(1) 내부에 수조(2)와 세탁조(3)가 구비되고 세탁조(3) 내부에 수류를 일으키는 펄세이터(4)가 설치된다. 또한 수조(2) 저면에 세탁조(3)와 펄세이터(4)를 선택적으로 구동시키는 모터(5) 및 동력절환부재(5a)가 설치된다. 또한 수조(2)는 본체(1) 내부의 사방으로 설치된 걸이봉(6)에 매달려 설치된다. 이때 걸이봉(6)의 하단에 스프링(6b)이 내장된 댐퍼(6a)가 설치되어 수조(2)의 진동이 완화된다.In general, as shown in FIG. 1, the washing machine includes a water tank 2 and a washing tank 3 in the main body 1, and a pulsator 4 for generating water flow in the washing tank 3 is installed. In addition, a motor 5 and a power switching member 5a for selectively driving the washing tank 3 and the pulsator 4 are provided at the bottom of the water tank 2. In addition, the water tank 2 is installed hanging on the hook rod 6 installed in all directions inside the main body 1. At this time, the damper (6a) having a spring (6b) is installed at the lower end of the hook rod (6) to reduce the vibration of the water tank (2).
이처럼 구성된 종래의 세탁기는 세탁시 세탁조(3) 내부에 빨래감과 세탁수가 공급되고 모터(5)의 구동으로 동력절환부재(5a)가 정역회전 되면 펄세이터(4)에 의해 수류가 일어나면서 세탁이 진행된다. 또한 세탁 완료후 세탁수가 배수되고 세탁조(3)가 고속으로 회전되면서 원심력에 의해 빨래감이 탈수된다.In the conventional washing machine configured as described above, when washing and washing water are supplied to the washing tub 3 during washing, and the power switching member 5a is reversely rotated by the driving of the motor 5, washing occurs while the water flow is generated by the pulsator 4. Proceed. In addition, after the washing is completed, the washing water is drained and the washing tank 3 is rotated at a high speed so that the washing feeling is dehydrated by centrifugal force.
또한 세탁시 또는 탈수시 발생되는 진동은 수조(2) 쪽으로 전달되고 이 과정에서 본체(1)에 매달린 댐퍼(6a)에 의해 완화된다.In addition, vibration generated during washing or dehydration is transmitted to the water tank 2 and is dampened by the damper 6a suspended in the main body 1 in the process.
그러나 댐퍼(6a) 내부의 스프링(6b) 탄성계수가 일정하기 때문에 완충성이 저하되는 단점이 있다. 즉 빨래감이 많으면 스프링(6b)에 가해지는 가압력이 커져 스프링(6b)이 압축된다. 이때 빨래감의 가압력이 스프링(6b)의 탄성력 보다 크기 때문에 완충성이 저하된다. 또한 빨래감이 적으면 스프링(6b)에 가해지는 가압력이 작아져 스프링이 압축되지 않고 압축력이 커지기 때문에 완충성이 저하되는 등의 단점이 있다.However, since the elastic modulus of the spring 6b in the damper 6a is constant, the buffering property is deteriorated. That is, if there is much washing, the pressing force applied to the spring 6b becomes large and the spring 6b is compressed. At this time, since the pressing force of the washing feeling is greater than the elastic force of the spring 6b, the buffering property is lowered. In addition, if the feeling of washing is small, there is a disadvantage that the pressing force applied to the spring 6b decreases and thus the buffering force is lowered because the compression force is increased without the spring being compressed.
본 고안은 수조 하부의 사방으로 형성된 다수개의 브래킷과; 상기 각 브래킷에 형성된 통로에 끼워져 승강되는 다수개의 스프링과; 상기 각 스프링의 외주연에 끼워지고 상기 수조를 감싸는 본체 내부에 걸이봉으로 매달려 설치된 다수개의 받이통과; 그리고 상기 각 스프링을 강제 승강시켜 받이통과 브래킷 사이의 스프링 유효권수를 가변시키는 모터를 구비하는 특징이 있다.The present invention is a plurality of brackets formed in all directions of the bottom of the tank; A plurality of springs inserted into and lifted through passages formed in the respective brackets; A plurality of receiving barrels fitted to the outer circumference of each spring and hanging with a hook rod inside the main body surrounding the tank; And it is characterized by having a motor for forcibly lifting each spring to vary the spring effective number of turns between the receiving cylinder and the bracket.

A plurality of brackets 10 are coupled in all directions below the water tank 2, and a passage 11 is formed at the center of each bracket 10.
또한 각 통로(11)에 끼워져 회전되면서 승강되는 스프링(20)이 마련되고 각 스프링(20)의 외주면에 톱니(21)가 형성된다. 또한 각 브래킷(10)의 일측에 브래킷(10)의 상측으로 돌출된 스프링(20)의 톱니(21)와 치합된 종동기어(42)가 구비되고 각 종동기어(42)는 모터(40)로 정역회전되는 구동기어(41)와 치합된다.In addition, springs 20 are inserted and rotated while being inserted into the respective passages 11, and teeth 21 are formed on the outer circumferential surface of each spring 20. In addition, a driven gear 42 engaged with the teeth 21 of the spring 20 protruding upward of the bracket 10 is provided at one side of each bracket 10, and each driven gear 42 is connected to the motor 40. It meshes with the drive gear 41 which rotates forward and backward.
또한 각 스프링(20)의 외주연에 끼워지는 받이통(30)이 구비되고 각 받이통(30)의 상단에 양쪽으로 갈라져 각 브래킷(10)의 양측을 감싸는 연결구(31)가 형성된다. 또한 각 연결구(31)의 상단 중앙에 걸이봉(32)의 하단이 결합되고 이들 걸이봉(32)의 상단이 본체(1)의 내측 상부에 매달려 설치된다.In addition, the receiving barrel 30 is provided to be fitted to the outer circumference of each spring 20 is divided into both ends at the upper end of each receiving barrel 30 is formed with a connector 31 surrounding both sides of each bracket (10). In addition, the lower end of the hook rod 32 is coupled to the center of the upper end of each connector 31, the upper end of these hook rod 32 is installed hanging on the inner upper portion of the main body (1).
이처럼 구성된 본 고안은 제3(a)도에 도시된 바와 같이 수조(2) 하부의 사방으로 형성된 각 브래킷(10)에 스프링(20)이 끼워진다. 스프링(20)은 스크류 형태로 권회된 것이기 때문에 스프링(20)의 상단을 통로(11)에 끼운 다음 회전시키면 나선운동에 의해 스프링(20)이 통로(11)를 따라 브래킷(10)에 결합된다. 또한 스프링(20)이 결합되면 브래킷(10)의 상부에 형성된 종동기어(42)와 톱니(21)가 서로 체결된다. 또한 받이통(30)을 스프링(20)의 하측 외주연에 끼운 다음 상단에 형성된 연결구(31)가 걸이봉(32)과 결합되면 수조(2)가 매달려 설치된다.The present invention configured as described above is fitted with a spring 20 to each bracket 10 formed in all directions below the water tank 2, as shown in Figure 3 (a). Since the spring 20 is wound in the form of a screw, when the upper end of the spring 20 is inserted into the passage 11 and rotated, the spring 20 is coupled to the bracket 10 along the passage 11 by a spiral motion. . In addition, when the spring 20 is coupled, the driven gear 42 and the teeth 21 formed on the upper portion of the bracket 10 are fastened to each other. In addition, after inserting the receiving barrel 30 into the lower outer periphery of the spring 20, the connector 31 formed at the top is coupled to the hook rod 32, the water tank 2 is installed hanging.
즉 받이통(30)은 연결구(31)와 걸이봉(32)을 통하여 본체(1) 내부에 매달려 설치되고 수조(2)는 브래킷(10)과 스프링(20)을 통하여 받이통(30)에 놓인 상태가 유지된다.That is, the receiving barrel 30 is installed hanging inside the main body 1 through the connector 31 and the hook rod 32 and the water tank 2 is connected to the receiving barrel 30 through the bracket 10 and the spring 20. The state of laying is maintained.
이 같은 상태에서 모터(40)의 정역회전시 구동기어(41)를 통하여 종동기어(42)가 정역회전되고 이때 종동기어(42)와 치합된 톱니(21)를 따라 스프링(20)이 회전된다. 또한 스프링(20)이 회전되면 통로(11)를 따라 승강되고 스프링(20)의 탄성력이 조정된다.In this state, when the forward and reverse rotation of the motor 40, the driven gear 42 is reversed through the drive gear 41, and at this time the spring 20 is rotated along the teeth 21 engaged with the driven gear 42. . In addition, when the spring 20 is rotated, it is elevated along the passage 11 and the elastic force of the spring 20 is adjusted.
제3(a),(b)도는 스프링(20)의 탄성력이 조정된 상태를 나타낸 것으로서, 수조(2)의 하중이 브래킷(10)을 통하여 스프링(20)에 집중된다. 이때 브래킷(10) 하부의 스프링(20) 자유단에서 발생되는 탄성력에 의해 수조(2)가 지탱된다. 즉 스프링(20)은 브래킷(10)의 하단과 받이통(30) 저면 사이의 자유단에서 탄성력이 발생됨으로 이들 자유단의 길이 조절에 따라 스프링(20)의 유효권수가 조절됨으로 결국 탄성력이 조절된다.3 (a), (b) is a state in which the elastic force of the spring 20 is adjusted, the load of the water tank 2 is concentrated on the spring 20 through the bracket (10). At this time, the tank 2 is supported by the elastic force generated at the free end of the spring 20 under the bracket 10. That is, the spring 20 is the elastic force is generated at the free end between the bottom of the bracket 10 and the bottom of the receiving barrel 30, the effective number of the spring 20 is adjusted according to the length adjustment of these free ends, so the elastic force is finally adjusted do.
따라서 세탁, 탈수시 빨래감의 중량이 감지되고 이들 중량에 따라 무거운 중량의 빨래감이 세탁될 때 제3(a)도와 같이 스프링(20)의 유효권수를 증가시켜 탄성력이 증가되도록 한다. 또한 경량의 빨래감을 세탁할 때 제3(b)도와 같이 스프링(20)의 유효권수가 감소되도록 조정함으로서, 탄성력을 빨래감의 중량에 비례하여 조절할 수 있다.Therefore, when washing and dehydration, the weight of the laundry is sensed and when the heavy laundry is washed according to these weights, the effective number of the spring 20 is increased to increase the elastic force as shown in the third (a). Further, by adjusting the effective number of springs 20 as shown in FIG. 3 (b) when washing light laundry, the elastic force can be adjusted in proportion to the weight of the laundry.
본 고안에 따르면 스프링을 회전시켜 브래킷 하부와 받이통 사이의 유효권수를 조정함으로서, 경량의 빨래감을 세탁할 때 스프링의 탄성력이 감소되도록 하고 또한 중량의 빨래감을 세탁할 때 탄성력이 증가되도록 함으로서, 세탁시 발생되는 진동소음을 능동적으로 감소시킬 수 있는 효과가 있다.According to the present invention by rotating the spring to adjust the effective number between the lower bracket and the receiving container, by reducing the elastic force of the spring when washing the laundry light weight and also by increasing the elastic force when washing the weight laundry, There is an effect that can actively reduce the vibration noise generated during.
본 고안의 목적은 스프링을 승강시켜 빨래감의 중량에 따라 유효권수가 가변되어 빨래감의 가압력과 스프링의 탄성력이 서로 균형을 이루도록 함으로서, 세탁시 또는 탈수시 완충성이 향상되도록한 세탁기의 완충장치를 제공함에 있다.An object of the present invention is to provide a shock absorber of the washing machine to increase the cushioning force during washing or dehydration by balancing the pressing force of the laundry and the elastic force of the spring by varying the effective number according to the weight of the laundry by lifting the spring. Is in.
