The balancer(6) is installed concentrically with a drum shaft(4) engaged with a drum(3) so that the tub(2) vibrates tracing a perfect circle when double eccentricity occurs to reduce the amplitude of the tub(2) to prevent the tub(2) from beating a cabinet(1).

Description

직결식 드럼세탁기의 진동저감장치{device for damping in drum-type washing machine}Vibration reduction device of direct drum washing machine {device for damping in drum-type washing machine}

본 발명은 드럼세탁기에 관한 것으로서, 더욱 상세하게는 직결식 드럼세탁기의 탈수시 발생하는 터브의 진동을 저감시킬수 있도록 한 것이다.The present invention relates to a drum washing machine, and more particularly, to reduce the vibration of the tub generated during dehydration of the direct-type drum washing machine.

일반적으로, 드럼 세탁 방식은 세제와 세탁수 및 세탁물이 드럼 내에 투입된 상태에서, 모터의 구동력을 전달받아 회전하는 드럼과 세탁물의 마찰력을 이용하여 세탁을 행하는 방식으로서, 세탁물의 손상이 거의 없고, 세탁물이 서로 엉키지 않으며, 두드리고 비벼빠는 세탁효과를 낼 수 있다.In general, the drum washing method is a method in which the laundry is performed using the friction force of the rotating drum and the laundry by receiving the driving force of the motor while the detergent, the washing water, and the laundry are put in the drum. These don't get tangled with each other, and can be washed and pounded.

도 1 및 도 2를 참조하여 종래 드럼세탁기의 구조에 대해 간략히 설명하면 다음과 같다.Referring to Figures 1 and 2 briefly describe the structure of a conventional drum washing machine as follows.

도 1은 종래의 드럼세탁기 구성을 나타낸 종단면도이고, 도 2는 도 1의 Ⅰ-Ⅰ선을 나타낸 정면도로서, 캐비닛(1) 내측에 터브(2)가 설치되고, 상기 터브(2) 내측 중앙에는 드럼(3)이 회전가능하게 설치된다.1 is a vertical cross-sectional view showing a conventional drum washing machine configuration, and FIG. 2 is a front view showing the line I-I of FIG. 1, wherein a tub 2 is installed inside the cabinet 1, and the inner center of the tub 2 is provided. The drum 3 is rotatably installed.

그리고, 상기 터브(2) 하부측에는 모터(5a)가 설치되고, 상기 모터(5a)에는 모터 풀리(8)가 축연결된다.In addition, a motor 5a is installed at the lower side of the tub 2, and a motor pulley 8 is axially connected to the motor 5a.

한편, 상기 드럼(3) 후방에는 모터(5a)의 구동력을 전달하는 드럼 샤프트(4)가 설치되고, 상기 드럼 샤프트(4)에는 드럼 풀리(9)가 결합된다.Meanwhile, a drum shaft 4 is installed at the rear of the drum 3 to transmit a driving force of the motor 5a, and a drum pulley 9 is coupled to the drum shaft 4.

또한, 상기 드럼 샤프트(4) 상에 설치된 드럼 풀리(9)와 모터(5a)에 연결된 모터 풀리(8)는 동력전달요소인 벨트(10)에 의해 연결된다.In addition, the drum pulley 9 installed on the drum shaft 4 and the motor pulley 8 connected to the motor 5a are connected by a belt 10 which is a power transmission element.

그리고, 상기 캐비닛(1) 전방에는 도어(11)가 설치되고, 도어(11)와 터브(2)(Tub) 사이에는 가스켓(12)이 설치된다.A door 11 is installed in front of the cabinet 1, and a gasket 12 is installed between the door 11 and the tub 2.

또한, 상기 캐비닛(1) 상부면 내측과 터브(2) 외주면 상부측 사이에는 터브(2)를 지지하는 행잉 스프링(13)(Hanging spring)이 설치되고, 상기 캐비닛(1) 하부면 내측과 터브(2) 외주면 하부측 사이에는 탈수시 발생하는 터브(2)의 진동을 감쇠시키기 위한 프릭션 댐퍼(7)가 설치된다.In addition, a hanging spring 13 for supporting the tub 2 is installed between the inside of the upper surface of the cabinet 1 and the upper side of the outer peripheral surface of the tub 2, and the inside of the lower surface of the cabinet 1 and the tub. (2) A friction damper 7 is provided between the lower side of the outer circumferential surface to damp the vibration of the tub 2 generated during dehydration.

그리고, 상기 터브(2)의 전방측 외주면 상에는 밸런서(6a)(balancer)가 장착되어, 터브(2)의 후방에 설치됨과 동시에 터브(2) 전면에서 볼 때 도 2의 X축 및 Y축으로부터 일정거리 편심되어 설치된 모터(5a) 및 모터 풀리(8)와의 무게 불균형을 해소하도록 되어 있다.And a balancer 6a (balancer) is mounted on the front outer circumferential surface of the tub 2, which is installed at the rear of the tub 2 and from the X and Y axes of FIG. The weight imbalance with the motor 5a and the motor pulley 8 which are provided eccentrically at a fixed distance is solved.

이에 따라, 종래에는 탈수에 따른 드럼(3)의 고속 회전시 세탁물의 불균형에 의해 발생하는 터브(2)의 진동을 상기한 밸런서(6a)가 저감시키게 된다.Accordingly, the balancer 6a described above reduces vibrations of the tub 2 caused by the imbalance of laundry during the high speed rotation of the drum 3 due to dehydration.

그러나, 이와 같은 종래의 진동저감장치는 모터 풀리 및 드럼 풀리를 통해 모터의 구동력이 드럼(3)으로 전달되는 드럼세탁기에는 알맞지만 드럼(3)에 결합된 드럼 샤프트(4)에 모터가 직결되는 방식의 드럼세탁기에는 적용이 불가능하다.However, such a conventional vibration reducing device is suitable for a drum washing machine in which the driving force of the motor is transmitted to the drum 3 through the motor pulley and the drum pulley, but the motor is directly connected to the drum shaft 4 coupled to the drum 3. It is not applicable to the drum washing machine of the type.

즉, 종래에는 터브(2)를 전면에서 볼 때 X축 및 Y축에 대해 편심되게 설치된 모터(5a)와의 무게 균형을 고려하여 도 2에 나타낸 바와 같이 밸런서(6a)의 장착 위치가 결정되는 반면, 직결식 드럼세탁기에서는 정면에서 볼 때 모터가 동심되게 설치되기 때문에 종래의 밸런서(6a)를 그대로 적용할 수 없게 되는 문제점이 있다.That is, in the related art, the mounting position of the balancer 6a is determined as shown in FIG. 2 in consideration of the weight balance with the motor 5a installed eccentrically with respect to the X and Y axes when the tub 2 is viewed from the front. In the direct drum washing machine, since the motor is installed concentrically when viewed from the front, there is a problem in that the conventional balancer 6a cannot be applied as it is.

특히, 종래의 드럼세탁기에서는 탈수시 도 1에 나타낸 바와 같이 세탁물이 드럼(3)의 전·후방에 각각 위치함과 동시에 도 2에 나타낸 바와 같이 세탁물이 대각선 방향에 각각 위치한 복편심 상태에서 탈수가 진행될 경우, 세탁물의 불평형량에 기인한 힘에 의해 진동이 도 8에 나타낸 바와 같이 타원형으로 나타나게 되며 터브(2)의 최대 진동폭이 매우 커지게 된다.In particular, in the conventional drum washing machine, when dewatering, laundry is placed in front and rear of the drum 3, respectively, and at the same time, laundry is dehydrated in a eccentric state in which the laundry is positioned diagonally, respectively. If proceeding, the vibration due to the force due to the unbalance of the laundry appears to be elliptical as shown in Figure 8 and the maximum vibration width of the tub (2) becomes very large.

이때, 불평형량이 클 경우에는 터브(2)가 외조에 부딪히는 현상이 발생하게 되며, 이에 따라 소음이 증폭되며, 진동이 심한 경우에는 세탁기 전체가 이동하는 워킹현상이 발생하게 된다.At this time, when the unbalance amount is large, the tub 2 hits the outer tub, and thus the noise is amplified, and when the vibration is severe, a walking phenomenon occurs in which the entire washing machine moves.

본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 직결식 드럼세탁기의 밸런싱(balancing) 구조를 개선하여 탈수시 터브에서 발생하는 진동을 효과적으로 저감시키며, 특히 복편심 발생시에도 터브의 진동을 효과적으로 저감시킬 수 있도록 한 드럼세탁기의 진동저감장치를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, by improving the balancing (balancing) structure of the direct-type drum washing machine to effectively reduce the vibration generated in the tub when dewatering, in particular to reduce the vibration of the tub even in the case of a double eccentricity It is an object of the present invention to provide a vibration washing device for a drum washing machine.

To; A drum washing machine is provided on the front of the tub, in which a ring balancer is installed to balance weight of the motor behind the tub to reduce vibration of the tub when dewatering.

이하, 본 발명의 실시예를 첨부도면 도 3 내지 도 8을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 8.

먼저, 본 발명의 제1실시예에 따른 드럼세탁기에 대해 설명하면 다음과 같다.First, the drum washing machine according to the first embodiment of the present invention will be described.

도 3은 본 발명의 제1실시예에 따른 진동저감장치가 적용된 드럼세탁기 구성을 나타낸 종단면도이고, 도 4는 도 3의 Ⅱ-Ⅱ선을 나타낸 정면도이며, 도 5는 도 3의 밸런서를 나타낸 사시도로서, 본 발명은 외형을 이루는 캐비닛(1)과, 상기 캐비닛(1) 내측에 설치되는 터브(2)와, 상기 터브(2) 내에 설치되는 드럼(3)과, 상기 드럼(3)에 결합된 드럼 샤프트(4)에 직결되는 모터(5)를 구비한 드럼세탁기에 있어서; 상기 터브(2)의 전면에, 상기 터브(2) 후방의 모터(5)에 대해 무게 균형을 이루도록 설치되어 탈수시 터브(2)의 진동을 저감시키게 되는 링(ring)형상의 밸런서(6)가 장착되어 구성된다.3 is a longitudinal sectional view showing the drum washing machine configuration to which the vibration reducing device according to the first embodiment of the present invention is applied, FIG. 4 is a front view showing the II-II line of FIG. 3, and FIG. 5 shows the balancer of FIG. As a perspective view, the present invention relates to a cabinet (1) forming an outline, a tub (2) installed inside the cabinet (1), a drum (3) provided in the tub (2), and the drum (3). A drum washing machine having a motor (5) directly connected to an associated drum shaft (4); Ring-shaped balancer 6 is installed on the front of the tub 2 to balance the weight of the motor 5 behind the tub 2 to reduce vibration of the tub 2 when dewatering. It is configured to be equipped.

이 때, 상기 밸런서(6)는 주철등의 금속 재질로 이루어짐이 바람직하며, 콘크리트 조성체등 밀도가 비교적 높은 재질이면 어떠한 재질도 적용 가능하다.At this time, the balancer 6 is preferably made of a metal material such as cast iron, any material can be applied as long as the material is a relatively high density, such as concrete composition.

이와 같이 구성된 본 발명의 제1실시예에 따른 드럼세탁기의 작용은 다음과 같다.The operation of the drum washing machine according to the first embodiment of the present invention configured as described above is as follows.

먼저, 본 발명의 밸런서(6)는 도 3에 나타낸 바와 같이 드럼세탁기를 측면에서 볼 때 터브(2) 후방에 위치한 모터(5)에 대칭되게 터브(2) 전면에 고정되어, 세탁기의 무게중심을 지나는 수직선을 중심으로 터브(2) 전·후방의 무게 균형이 이루어지도록 작용하게 된다.First, the balancer 6 of the present invention is fixed to the front of the tub (2) symmetrically to the motor (5) located behind the tub (2) when viewed from the side as shown in Figure 3, the center of gravity of the washing machine The weight balance of the front and rear of the tub (2) is made around the vertical line passing through the.

한편, 상기 밸런서(6)는 드럼세탁기를 전면에서 볼 때, 도 4에 나타낸 바와 같이 거의 링 형상을 이루므로써 좌·우 및 상·하 방향으로의 무게 균형이 유지되도록 작용하게 된다.On the other hand, the balancer (6) when the drum washing machine is viewed from the front, as shown in Figure 4 to form a substantially ring shape to act to maintain the weight balance in the left, right and up and down directions.

따라서, 본 발명의 밸런서(6)는 터브(2) 전·후방 및 터브(2) 좌·우 방향, 그리고 터브(2) 상·하방향에 대해 무게 균형이 유지되도록 하여, 탈수시 세탁물의 편심에 의해 발생하는 터브(2)의 진동을 효과적으로 저감시키게 된다.Therefore, the balancer 6 of the present invention maintains the weight balance in the front and rear of the tub 2, the left and right directions of the tub 2, and the up and down directions of the tub 2, so that the laundry is eccentric when dewatering. The vibration of the tub 2 generated by this is effectively reduced.

특히, 본 발명의 밸런서(6)는 세탁물의 복편심이 발생할 경우, 종래 드럼세탁기의 밸런서(6)에 비해 더욱 효과적으로 진동을 저감시키게 된다.In particular, the balancer 6 of the present invention is to reduce the vibration more effectively than the balancer 6 of the conventional drum washing machine when the double eccentricity of the laundry occurs.

즉, 본 발명에서는 밸런서(6)가 터브(2) 전면에 드럼(3)에 결합된 드럼 샤프트(4)와 동심(同心)을 이루도록 설치되어 있으므로 인해, 복편심 발생시 터브(2)가 도 8에 나타낸 바와 같이 정원(正員) 형태의 궤적을 그리며 진동하게 되는데, 이때의 진동폭은 타원형을 이루는 종래 드럼세탁기에서의 진동폭에 비해 현저히 작아지게 된다.That is, in the present invention, because the balancer 6 is installed in the front of the tub 2 to be concentric with the drum shaft 4 coupled to the drum 3, the tub 2 is generated when the eccentricity is generated. As shown in the figure is vibrating in the form of a trajectory, the vibration width is significantly smaller than the vibration width in the conventional drum washing machine to form an oval.

따라서, 본 발명에 따른 드럼세탁기에서는 복편심이 발생하고 복편심으로 인한 불평형량이 매우 커지더라도 터브(2)의 진동폭이 작아 터브(2)가 캐비닛(1)을 치게 되는 등의 현상이 방지된다.Therefore, in the drum washing machine according to the present invention, even if the eccentricity is generated and the amount of unbalance due to the eccentricity becomes very large, the vibration width of the tub 2 is small and the phenomenon in which the tub 2 hits the cabinet 1 is prevented.

한편, 도 6은 본 발명의 다른 실시예에 따른 드럼세탁기 구성을 나타낸 종단면도이고, 도 7은 도 6의 Ⅲ-Ⅲ선을 나타낸 정면도로서, 이 경우에는 전면에 외측으로 갈수록 후방으로 경사진 경사면(100)이 형성된 터브(2)에 있어서, 밸런서(6)가 터브(2) 전면에 형성된 경사면(100) 전방의 사공간(死空間:dead space)상에 구비된다.On the other hand, Figure 6 is a longitudinal cross-sectional view showing the configuration of a drum washing machine according to another embodiment of the present invention, Figure 7 is a front view showing the line III-III of Figure 6, in this case inclined surface inclined backward toward the outside toward the front in this case In the tub 2 in which the 100 is formed, a balancer 6 is provided on a dead space in front of the inclined surface 100 formed on the front surface of the tub 2.

이 때, 상기 밸런서(6)는 가장 폭이 큰 부분의 치수가 터브(2)의 전단부를 벗어나지 않는 폭으로 형성되고, 밸런서(6) 후면은 상기 터브(2)의 경사면(100)에 대해 형합하도록 동일 사면을 갖도록 형성됨이 바람직하다.At this time, the balancer (6) is formed in a width such that the dimension of the largest part does not escape the front end of the tub (2), the balancer (6) the back side is formed with respect to the inclined surface 100 of the tub (2) It is preferable to be formed to have the same slope so as to.

한편, 상기에서 사공간(死空間)이라 함은 드럼세탁기 내부에서 어떤 역할도 수행하지 않는 공간을 말한다.On the other hand, the dead space (死 空間) in the above means a space that does not play any role in the drum washing machine.

이와 같이 구성된 본 발명의 다른 실시예에서는 터브(2) 전면의 사공간 상에 밸런서(6)가 위치하게 되므로 다른 부품과의 간섭이 없고 밸런서(6)와 캐비닛(1)과의 간섭을 없애기 위해 캐비닛(1)의 치수를 키우지 않아도 되므로, 동일 밸런싱 성능을 발휘할 경우 전술한 제1실시예에 비해 제품의 콤팩트화가 가능하다.In another embodiment of the present invention configured as described above, since the balancer 6 is positioned on the dead space in front of the tub 2, there is no interference with other components and the interference between the balancer 6 and the cabinet 1 is eliminated. Since it is not necessary to increase the dimensions of the cabinet 1, the product can be made compact in comparison with the above-described first embodiment when the same balancing performance is achieved.

한편, 도 7은 종래 드럼세탁기와 본 발명에 따른 드럼세탁기에서 동일한 복편심량 발생시 터브(2)의 진동형태 및 진동폭의 크기를 나타낸 비교도로서, 본 발명의 각 실시예에 따른 진동저감장치가 적용된 드럼세탁기의 경우에는 복편심량 발생시 진동 궤적이 원형임에 반해, 종래의 진동저감장치가 적용된 드럼세탁기에서는 복편심량 발생시 진동 궤적 타원형을 이루며, 진동 궤적의 전체 폭의 크기가 종래(WC)에 비해 본 발명(WI)에서 보다 작은 값(WC〉WI)으로 나타남을 통해, 본 발명이 종래에 비해 진동 저감 효과가 향상됨을 확인할 수 있다.On the other hand, Figure 7 is a comparison diagram showing the vibration type and the amplitude of the vibration width of the tub (2) when the same amount of eccentricity in the conventional drum washing machine and the drum washing machine according to the present invention, the vibration reduction device according to each embodiment of the present invention is applied In the case of the drum washing machine, the vibration trajectory is circular when a double core weight is generated, whereas in the drum washing machine to which the conventional vibration reducing device is applied, the vibration trajectory is elliptical when the double core weight is generated, and the overall width of the vibration trajectory is larger than the conventional (W C ). In the present invention (W I ) through the smaller value (W C > W I ), it can be seen that the present invention is improved vibration reduction effect compared to the prior art.

이상에서와 같이, 본 발명은 직결식 드럼세탁기의 진동저감 구조를 개선하여 탈수시 터브(2)에서 발생하는 진동을 효과적으로 저감시키므로써 탈수 성능을 향상시킬 수 있게 된다.As described above, the present invention can improve the dewatering performance by improving the vibration reduction structure of the direct-type drum washing machine to effectively reduce the vibration generated in the tub (2) when dewatering.

특히, 복편심 발생시에도 터브(2)의 진동을 효과적으로 저감시킬 수 있게 되므로써 탈수 성능 뿐만 아니라 제품의 내구성 및 신뢰성을 향상시킬 수 있게 된다.In particular, the vibration of the tub 2 can be effectively reduced even in the occurrence of a double eccentricity, thereby improving durability and reliability of the product as well as dehydration performance.
