본 발명은 세탁기 저수조 감지스위치구조에 관한 것으로, 특히 세탁물의 탈수 행정도중 세탁조내에 담겨져 있는 세탁물의 편중으로 인한 흔들림 또는 구동부로부터 발생된 진동에 의한 저수조의 언발란스가 발생시 상기 저수조의 언발란스를 정확히 감지하여 저수조가 외체를 때리지 않도록 하므로서 충격에 의한 부품의 파손 및 소음을 방지할수 있도록 한 세탁기의 저수조 감지스위치구조에 관한 것이다.The present invention relates to a washing machine reservoir detection switch structure, and in particular, when the unbalance of the reservoir caused by shaking or vibration generated from the driving unit due to the bias of the laundry contained in the washing tank during the dehydration stroke of the laundry, the unbalance of the reservoir is accurately sensed. It is related with the structure of the water tank sensing switch of the washing machine to prevent damage to the parts and noise caused by the impact while not hitting the outer body.
일반적으로 세탁기의 언발란스 감지장치는 세탁물의 세탁 즉, 탈수행정도중 고속회전하는 세탁조가 편중된 상태에서 회전하는 것을 감지시켜 주도록 되어 있는 것이다.In general, the unbalance detection device of the washing machine is intended to detect that the laundry rotates in a state in which the washing tank that rotates at a high speed during dehydration, that is, dehydration degree.
예를 들어, 세탁조내에 담겨진 세탁물이 고르게 분포되어 있지 않고 일측으로 몰린 상태에서 탈수행정을 수행하게 되면 하부 중앙에 결합된 탈수축을 중심으로 하여 고속 회전되는 세탁조가 회전원심력과 세탁물의 평중에 의하여 세탁조의 상단부가 외측으로 큰 쾌적을 그리면서 회전됨에 따라 언발란스가 발생된다.For example, when the laundry contained in the washing tank is not evenly distributed and is driven to one side, the dehydrating stroke is performed by rotating centrifugal force and the flatness of the laundry by rotating centrifugal force. Unbalance occurs as the upper end is rotated while drawing great comfort outward.
상기와 같이 세탁조가 큰 쾌적을 그리면서 탈수행정이 이루어짐에 따라 상기 세탁조의 흔들림이 저수조로 전달되어 걸이봉에 의해 외체의 내부에 매달려 있는 저수조가 흔들리게 되고, 이러한 상태에서 심하게 일어난다면 저수조가 외체의 내면을 때리는 현상이 일어나 세탁조 및 외체의 파손 및 충격으로 인한 소음이 크게 발생되는 단점이 있었던 것이다.As the washing tank draws a great comfort as described above, the shaking of the washing tank is delivered to the reservoir as the washing tank is shaken, and the reservoir hanging from the inside of the outer body is shaken by a hook rod, and if the storage tank is severely in this state, the tank is external. Hitting the inner surface of the phenomenon occurred due to the noise caused by the damage and impact of the washing tank and the outside.
따라서, 상기의 저수조가 흔들리는 것을 탑커어버의 후방 일측에 설치되어 있는 안전 스위치가 도어의 개폐와 함께 감지하여 저수조가 일정각도 이상으로 흔들리게 되면 이를 언발란스로 인식하여 탈수행정을 일시적으로 정지시켜 주도록 되어 있는 것이다. 즉, 탑커어버의 후방 일측 내부에 위치하는 스위치의 전방측에 위치한 상태에서 탑커어버의 바닥면을 관통하여 외체와 저수조 사이에 안전레버가 위치하도록 한 상태에서 탈수행정을 수행하는 도중 세탁물의 편중과 구동부의 진동으로 인하여 저수조가 서서히 흔들리게 되어 상기 저수조가 안전레버를 때리게 되는데, 설정된 주기로 안전레버를 때리지 않을 경우에는 언발란스로 인식하지 않고, 저수조가 안전레버를 때리는 주기가 일정한 경우 저수조의 언발란스로 인식하여 탈수행정을 정지시켜 줌에 따라 언발란스로 인한 각 부속품의 파손을 방지하여 주게 됨은 물론, 저수조가 외체를 때리게 되지 않아 충격으로 이한 소음을 방지하게 되는 것이다.Therefore, when the water tank shakes more than a certain angle, the safety switch installed at the rear side of the top cover detects that the water tank is shaken, and when the water tank is shaken by a certain angle, it is recognized as unbalanced to temporarily stop the dehydration stroke. It is. That is, during the dehydration stroke while the safety lever is located between the outer body and the water tank through the bottom surface of the top cover in a state located on the front side of the switch located inside the rear one side of the top cover, Due to the vibration of the driving unit, the reservoir is slowly shaken, and the reservoir strikes the safety lever.If the reservoir does not hit the safety lever at the set cycle, it is not recognized as unbalanced.If the reservoir strikes the safety lever, the reservoir is recognized as unbalanced. By stopping the dehydration stroke to prevent damage to each accessory due to unbalance, as well as to prevent the noise caused by the impact because the reservoir does not hit the outer body.
그러나, 상기와 같은 종래의 언발란스감지장치는 탈수행정시 흔들리는 저수조가 안전레버를 때리게 되면 충격에 의해 회동되는 각도에 따라 안전레버의 상단부가 도어감지레버를 상승시켜 주도록 하여 스위치를 온, 오프시켜 주므로서 저수조의 언발란스를 감지하도록 되어 있어 저수조의 언발란스를 정확히 감지하지 못하게 되는 단점이 있고, 또한 상기와 같이 저수조의 언발란스를 정확히 감지하지 못할 경우에는 저수조가 외체를 때리게 되는 현상이 일어나 충격으로 인한 파손 및 소음이 심하게 발생되는 등의 제반결함이 있었던 것이다.However, in the conventional unbalance detection device as described above, when the water tank shaken during the dehydration stroke hits the safety lever, the upper end of the safety lever raises the door detection lever according to the angle rotated by the impact so that the switch is turned on and off. It is designed to detect the unbalance of the reservoir, which makes it impossible to accurately detect the unbalance of the reservoir.In addition, when the unbalance of the reservoir is not accurately detected, the reservoir hits the outer body, causing damage due to impact and There was a lot of defects such as excessive noise.
따라서, 본 발명의 목적은 세탁물의 탈수행정도중 세탁조내에 담겨져 있는 세탁물의 편중으로 인한 흔들림 또는 구동부로 부터 발생된 진동에 의한 저수조의 언발란스가 발생기 상기 저수조의 언발란스를 정확히 감지하여 저수조가 외체를 때리지 않도록 하므로서 충격에 의한 부품의 파손 및 소음을 방지할수 있도록 한 세탁기의 저수조 감지스위치구조를 제공함에 있다.Accordingly, an object of the present invention is to accurately detect the unbalance of the reservoir caused by shaking or vibration caused by the bias of the laundry contained in the washing tank during the dehydration of the laundry, so that the reservoir does not hit the outer body. Therefore, to provide a water tank detection switch structure of a washing machine to prevent damage and noise of parts due to impact.

The inside of the washing tank is configured to contain the laundry 3, the inner bottom of the washing tank is rotated left and right alternately by the drive of the drive unit 4 is composed of a rotary blade (5) for rotating the wash water. In the unbalance detection device of the washing machine consisting of an unbalance detection switch (6) for detecting the unbalance of the water tank at a predetermined position inside the upper part of the outer body, the body portion 61 that is fastened and fixed to the inner surface of the outer body has a square shape Space portions 613A and 613B are formed before and after the center partition wall 611, and the through hole 611 and the through hole 616 in which the space portion 613A and the partition wall communicate with each other in the center of the main body. Constitute both sides of the space This constitutes a guide ball 615.
또한, 상기 본체부의 전방측에 위치하도록 하여 저수조의 언발란스시 접지되는 접지부(62) 즉, 본체의 전방으로 부터 통공(614)에 끼워진 축수(622)에 의해 저수조의 접지에 의해 전, 후로 이동되는 접지판(621)을 구성하고, 상기 접지판의 후면 양측에 가이드공에 끼워져 이동을 가이드시켜 주는 가이드축(623)을 구성하며, 접지판의 전면에는 저수조의 충격을 완충시켜 줄수 있도록 하는 완충재(624)를 구성한다.In addition, by moving to the front and back by grounding the reservoir by the ground portion 62 which is located at the front side of the main body portion and grounded during unbalance of the reservoir, that is, the bearing 622 fitted into the through hole 614 from the front of the main body. The ground plate 621 is formed, and the guide shaft 623 is inserted into the guide hole on both sides of the ground plate to guide the movement, and the shock absorbing material to buffer the shock of the reservoir in the front of the ground plate Configure 624.
그리고, 구획벽 중앙에 구성된 관통공에 끼워진 상태에서 전, 후로 임의 이동가능 하도록 하는 작동관(631)이 구성되고, 상기 작동관의 전면과 접지판의 축수(622) 후면에 각각 접지된 상태에서 자체의 탄성력으로 인해 작동관을 후방으로 밀어주는 탄성스프링(632)으로 구성된 탄성부(63)를 구성하고, 후방의 공간부(613B)에 위치하도록 한 상태에서 작동관의 이동에 따라 접지편(643)이 접지단자(642)를 단락시켜 주면서 전원을 온, 오프시켜 주는 마이크로스위치(64)로 구성하여 되는 것이다.And, in the state of being fitted in the through-hole configured in the center of the partition wall, the operation tube 631 is configured to be able to move randomly before and after, and in the state respectively grounded on the front of the operation tube and the back of the shaft 622 of the ground plate Due to its elastic force, it constitutes an elastic portion 63 composed of an elastic spring 632 which pushes the operation tube to the rear, and is grounded in accordance with the movement of the operation tube in a state of being positioned in the rear space 613B. 643 is configured as a micro switch 64 that turns the power on and off while shorting the ground terminal 642.
상기와 같은 구성으로 하는 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention having the configuration as described above are as follows.
먼저, 세탁수가 급수된 상태에서 구동부(4)의 구동에 의해 회전익(5)이 설정된 시간동안, 좌,우 교호로 회전되면서 회류되는 세탁수의 마찰수류로 인하여 세탁물에 뭍어있는 찌든때가 제거되는 것이고, 이러한 상태로 하여 세탁 및 헹굼행정이 완료되면 세탁수가 배수된 상태에서 탈수행정 즉, 구동부(4)의 구동에 의해 세탁조(3)가 일측방향으로 고속 회전됨에 따라 상기 세탁조(3)의 회전원심력으로 인해 세탁조의 내부에 담겨져 있는 세탁물이 세탁조의 내주면에 달라붙어 있는 상태로 하여 세탁물에 침전되어 있는 세탁수가 강제로 빠져 나가므로 인하여 탈수가 수행되는데, 상기와 같이 탈수행정 도중 세탁조내에 담겨 있는 세탁물은 세탁행정시 발생된 세탁물의 꼬임으로 인하여 세탁조(3)내에 고루게 분포되어 있지 않고 일측으로 몰린 상태에서 탈수행정이 수행됨에 따라 세탁물의 편중으로 인하여 세탁조가 일측으로 기울어진 상태에서 회전이 이루어지게 되고, 이러한 상태에서 세탁조의 회전력이 빨라질수록 세탁조의 흔들림이 갈수록 커지게 되어 저수조(2)가 흔들리게 되는 것이며, 또한 구동부(4)의 구동으로 부터 발생되는 진동에 의해 저수조가 심하게 흔들리게 된다.First, when the rotor blades 5 are driven by the driving unit 4 in a state in which the washing water is supplied, the stings stuck in the laundry are removed due to the frictional flow of the washing water that is rotated alternately left and right. When the washing and rinsing stroke is completed in this state, the washing centrifugal force of the washing tub 3 is rotated at a high speed in one direction by the dehydration stroke, that is, the driving of the driving unit 4 while the washing water is drained. Due to this, the laundry contained in the inside of the washing tank is stuck to the inner circumferential surface of the washing tank, and dehydration is performed because the washing water deposited in the laundry is forced out. The laundry contained in the washing tank during the dehydration administration is performed as described above. Due to the twisting of the laundry generated during the washing administration, it is not evenly distributed in the washing tank 3 and dehydrated while being driven to one side. As the administration is performed, the rotation of the washing tank is inclined to one side due to the bias of the laundry, and as the rotational force of the washing tank increases in this state, the shaking of the washing tank becomes larger and the reservoir 2 is shaken. In addition, the reservoir is violently shaken by the vibration generated from the driving of the drive unit (4).
상기와 같이 저수조의 흔들림이 발생된 상태에서 탈수행정이 수행되게 되는데, 저수조의 흔들림이 심하지 않아 저수조(2)가 외체(1)의 내부 상단 일측에 설치되어 있는 언발란스감지스위치(6) 즉, 본체(611)의 전방에 위치하고 있는 접지판(621)에 흔들리는 저수조(2)가 접지되지 않게 되면 언발란스로 인식되지 않아 계속해서 탈수행정을 수행하게 되는 것이고, 저수조의 흔들림이 심해 상기의 저수조(2)가 접지판(621)을 때리게 될 경우 탄성스프링(632)의 탄성력으로 인하여 본체부(611)의 전방으로 밀려있던 접지판이 가이드축(623)의 가이드에 의해 탄성스프링을 압축하면서 후방으로 밀리게 되고, 압축되는 탄성스프링(632)의 탄발력으로 인하여 구획벽(612)의 중앙에 구성된 관통공(616)에 끼워져 있는 작동관(631)을 후방으로 밀어주므로서 상기 작동관의 후면에 접지되어 있는 접지편(643)이 접지단자(642)에 접지가 이루어지므로서 저수조의 언발란스를 인식하게 되는 것이다.The dehydration stroke is performed in a state where the shake of the reservoir is generated as described above. The shake of the reservoir is not so severe that the reservoir 2 is installed on the inner upper side of the outer body 1, that is, the main body. If the reservoir 2 swinging on the ground plate 621 located in front of the 611 is not grounded, it is not recognized as unbalanced and continues to perform the dehydration stroke, and the shake of the reservoir is severe, so that the reservoir 2 When the ground plate 621 hits the ground plate 621 is pushed forward by the guide of the guide shaft 623 due to the elastic force of the elastic spring 632 pushes the elastic spring back Due to the elastic force of the elastic spring 632 to be compressed, the rear side of the operating tube is pushed to the rear by pushing the operating tube 631 fitted in the through hole 616 configured at the center of the partition wall 612 to the rear. The grounded piece 663 is grounded to the ground terminal 642, thereby recognizing the unbalance of the reservoir.
그리고, 흔들리는 저수조가 접지판을 지속적으로 눌러주고 있지 않고 접지판의 반대방향으로 이동될 경우에는 저수조의 충격으로 인해 후퇴하고 있던 접지판(611)이 압축되어 있던 탄성스프링(632)의 탄발력으로 인해 본체부(611)의 전방으로 이동됨과 아울러, 작동관(631)이 이동되면서 접지단자에 접지되어 있던 접지편(643)이 떨어지게 되는 것이다.In addition, when the shaking tank is not pressed against the ground plate continuously and is moved in the opposite direction of the ground plate, the elastic spring 632 of the elastic spring 632, which is retracted by the impact of the reservoir, is compressed. Due to the movement to the front of the main body portion 611, while the operating tube 631 is moved, the ground piece (643) that is grounded to the ground terminal is to fall.
상기와 같은 작동에 의해 저수조의 언발란스를 감지하게 되는데, 저수조의 흔들림에 의해 마이크로스위치(6)가 일정한 주기로 접지되지 않게 되면 언발란스로 인식하지 않고 지속적으로 탈수행정을 수행하게 되는 것이며, 상기와 같이 마이크로스위치가 일정한 주기로 접지가 이루어지게 되면 저수조의 언발란스로 인식하여 탈수행정을 일시적으로 정지시켜 주게 되는 것이다.By detecting the unbalance of the reservoir by the operation as described above, if the micro switch 6 is not grounded at regular intervals due to the shaking of the reservoir, the dehydration stroke is continuously performed without being recognized as an unbalance. If the switch is grounded at regular intervals, it will recognize that the reservoir is unbalanced and stop the dehydration stroke temporarily.
이상에서와 같이 본 발명은 탈수행정도중 세탁물의 편중이나 구동부의 진동으로 인해 저수조가 흔들릴 경우 상기 저수조의 흔들림을 탄성스프링으로 탄지되어 있는 접지판의 전, 후로 이동하면서 탄성스프링과 함께 이동하는 작동관에 의해 마이크로 스위치를 단락시켜 주도록 하여 일정한 주기로 하여 지속적으로 마이크로스위치를 단락시켜 주게 되면 저수조의 언발란스로 감주시켜 탈수행정을 일시적으로 정지시켜 주도록 하고 있어 저수조의 언발란스를 정확히 감지하게 되는 효과가 있고, 이로 인해 저수조가 외체를 때리게 되는 일이없어 제품의 파손 및 충격으로 인한 소음이 발생되지 않게되는 등의 효과가 있는 것이다.As described above, the present invention is an operation pipe that moves together with the elastic spring while moving the front and back of the ground plate which is supported by the elastic spring when the reservoir is shaken due to the deflection of the laundry or the vibration of the driving unit during the dehydration degree. By short circuiting the microswitch by short circuiting the microswitch at regular intervals, it is possible to stop the dehydration stroke temporarily by turning off the unbalance of the reservoir and thus to detect the unbalance of the reservoir accurately. Due to this, the water tank does not hit the outer body, and there is an effect such that no noise is generated due to damage and impact of the product.
