Description

세탁기의 탈수시간 자동조절장치Automatic dehydration time adjusting device of washing machine

본 고안은 세탁기의 탈수시간 자동조절장치에 관한 것으로, 특히 세탁이 완료된 세탁물을 탈수시 설정된 탈수시간에 구애됨이 없이 탈수에 의해 배수되는 세탁수의 배수량을 감지하여 세탁수의 배수량이 없으면, 탈수가 자동으로 정지될수 있도록 한 세탁기의 탈수시간 자동조절장치에 관한 것이다.The present invention relates to a device for automatically adjusting the dehydration time of a washing machine, and in particular, if the washing is completed, the dehydration time of the washing water drained by dehydration is not detected without being bound to the set dehydration time. It relates to a dehydration time automatic control device of the washing machine to be automatically stopped.

일반적으로 세탁기는 세탁행정 및 헹굼행정이 완료되면 탈수행정을 수행하여 세탁물에 침전되어 있는 세탁수를 탈수시켜 주도록 되어있는 것으로서, 상기의 탈수행정은 세탁물의 량에 따라 탈수시간이 설정되어 상기 설정된 탈수시간동안 세탁조가 고속회전되면서 상기 세탁조의 회전원심력으로 인해 세탁물에 침전되어 있는 세탁수가 빠지게 되고, 세탁물로 부터 타진 세탁수를 배수관을 통해 외부로 배수가 이루어지도록 되어있는 것이다.In general, the washing machine is to dehydrate the washing water precipitated in the laundry by performing a dehydration stroke when the washing stroke and the rinsing stroke is completed, wherein the dehydration stroke is set to the dehydration time according to the amount of laundry, As the washing tank rotates at high speed for a time, the washing water precipitated in the laundry is removed due to the rotational centrifugal force of the washing tank, and the washed water from the laundry is drained out through the drain pipe.

그러나, 상기와 같은 종래의 탈수행정은 세탁물을 세탁시 설정된 세탁물의 량을 기준으로 하여 탈수시간이 설정되도록 되어 있으며, 상기와 같이 설정된 시간이 모자랄 경우 사용자가 직접 탈수시간을 임의로 설정하여 탈수가 이루어지도록 되어있는데, 이러한 경우 설정된 탈수시간 전에 세탁물에 침전되어 있는 세탁수의 탈수가 완료되더라도 설정된 시간동안 탈수행정이 이루이지도록 되어 있으므로서, 필요이상으로 탈수시간이 길어지게 되는 단점이 있으며, 필요이상으로 전력의 낭비를 가져오게 되는 등의 결함이 있었던 것이다.However, in the conventional dehydration operation as described above, the dehydration time is set on the basis of the amount of laundry set when washing the laundry. In this case, even if the dehydration of the wash water precipitated in the laundry before the set dehydration time is completed, the dehydration stroke is made for a set time, so that the dehydration time is longer than necessary, there is a disadvantage As a result, there was a defect such as waste of power.

따라서, 본 고안은 세탁물의 탈수시 설정된 탈수시간에 구애됨이 없이 세탁물의 탈수가 완료되면 탈수행정을 정지시켜 주어 전력의 낭비를 방지할수 있도록 한 것으로서, 이는 구동부의 구동에 의해 세탁조를 회전시켜 상기 세탁조의 회전원심력으로 인해 세탁물에 침전되어 있는 세탁수를 탈수시켜 주는 세탁기의 탈수장치에 있어서, 세탁수가 배수되는 배수관내에 배수되는 세탁수의 수압에 의해 배수관을 개폐시켜 주면서 설정된 탈수시간에 구애됨이 없이 탈수완료를 감지시켜 주는 탈수완료감지수단이 갖추어진 것을 특징으로 하는 것이다.Therefore, the present invention is to stop the dehydration stroke when the laundry is dewatered without being bound to the dehydration time set during the dehydration of the laundry to prevent waste of power, which is to rotate the washing tank by the drive of the drive unit In the dewatering device of the washing machine to dehydrate the wash water precipitated in the laundry due to the centrifugal force of the washing tank, it is bound by the set dehydration time by opening and closing the drain pipe by the water pressure of the wash water drained in the drain pipe to which the wash water is drained It is characterized in that the dehydration completion detection means for detecting the dehydration completion without.

상기의 탈수완료감지수단(500)은 배수관(400)의 일측에 내부와 연통된 상태로 하여 외측상부로 경사진 수용부(510)를 구성하고, 상기 수용부의 내부에 내삽되어 이동되면서 배수관을 차단시켜 주도록 부력을 갖는 밀폐볼(520)을 구성하며, 수용부의 끝단부에 밀폐볼의 이동을 감지하는 감지부(530)로 구성하여 되는 것이다.The dehydration completion detection means 500 is configured to be in communication with the inside on one side of the drain pipe 400 to constitute a receiving portion 510 inclined to the outside, and is inserted into the receiving portion to block the drain pipe. It constitutes a closed ball 520 having a buoyancy so as to be made, it is composed of a sensing unit 530 for detecting the movement of the sealed ball at the end of the receiving portion.

도면중 미설명 부호 600은 세탁 및 헹굼시 세탁수의 배수를 차단시켜 주는 배수밸브의 예시이다.Reference numeral 600 in the figure is an example of a drain valve that blocks the drain of the wash water during washing and rinsing.

상기와 같은 구성으로 하는 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention to the above configuration as follows.

먼저, 세탁을 수행하지 않을때에는 수용부(510)내에 수용되어 있는 밀폐볼(520)이 자중에 의해 배수관(400)을 차단하고 있는 상태이고, 배수밸브(600)도 잠겨있는 상태를 유지한다.First, when washing is not performed, the sealing ball 520 accommodated in the accommodating part 510 is blocking the drain pipe 400 by its own weight, and the drain valve 600 also remains locked.

이러한, 상태에서 세탁행정을 수행하기 위해 세탁수를 급수시켜 주게되면 급수 되는 세탁수가 배수관(400)을 통해 잠겨져 있는 배수밸브(600)에 까지 급수된 상태 에서 세탁수가 급수되게 되는데, 이때 배수관(400)에 위치하고 있는 세탁수의 수압에 의해 수용부(510)내에 위치하고 있는 밀폐볼(520)이 수용부내에서 부상되어 상기 수용부의 상단부에 위치하고 있는 감지부(530)에 접지하는데, 이때에는 감지부의 전원이 차단된 상태를 유지하고 있는 상태이므로서 세탁행정에는 아무런 장애를 주지않아 세탁수의 급수 및 세탁행정을 수행하게 된다.In such a state, when the washing water is supplied to perform the washing administration, the washing water is supplied to the drain valve 600 which is locked through the drain pipe 400, and the washing water is supplied to the wash water. The closed ball 520 located in the accommodating part 510 is floated in the accommodating part and grounded to the sensing part 530 located at the upper end of the accommodating part by the water pressure of the washing water located at Since the state is maintained in the blocked state does not impede the washing administration is to perform the water supply and washing administration of the washing water.

상기와 같은 상태로 하여 세탁수의 급수가 완료되면 구동부의 구동에 의해 회전 익을 회전시켜 주어 이로부터 일어나는 세탁수류에 의해 세탁물을 세탁시켜 주게 되고, 세탁행정이 완료되면 세탁물을 세탁시켜 주면서 오염된 더러운 세탁수를 배수시켜 주는 행정을 헹굼과 배수가 이루어질 때 까지 진행시켜 주어 세탁물을 깨끗이 세탁시켜 주게된다.When the water supply of the washing water is completed in the above state, the rotor blades are rotated by the driving of the driving unit, and the laundry is washed by the washing water generated therefrom. When the washing administration is completed, the laundry is washed and the soil is contaminated. The process of draining the wash water proceeds until the rinsing and draining is done to wash the laundry cleanly.

상기와 같이 세탁물의 헹굼후 배수가 이루어진 상태에서는 세탁물에 소정량의 세탁수가 침전된 상태에 있기 때문에 세탁수의 배수가 완료된 후 구동부의 구동에 의해 세탁조(200)를 일측방향으로 고속회전시켜 주어 상기 세탁조의 회전원심력에 의해 세탁물에 침전되어 있는 세탁수를 탈수시켜 주게된다.After washing the laundry as described above, since a predetermined amount of wash water is in a state in which the wash water is settled, the washing tank 200 is rotated at a high speed in one direction by the driving unit after the drainage of the wash water is completed. The rotary centrifugal force of the washing tank dehydrates the wash water that has settled in the laundry.

즉, 세탁물의 탈수시간은 세탁물의 량에 따라 자동으로 설정되어 있거나, 사용 자가 임의로 탈수시간을 설정한 상태에서 탈수행정을 수행하게 되는데, 탈수행정 전에는 제2도a에 도시된 바와같이 배수밸브가 열려있는 상태에서 세탁수가 배수되지 않아 수용부(510)내에 위치하고 있는 밀폐볼(520)이 자중으로 인해 하부로 떨어져 배수관(400)을 막고있는 상태에 있게된다.That is, the dehydration time of the laundry is automatically set according to the amount of laundry, or the dehydration stroke is performed while the user sets a dehydration time arbitrarily. Before the dehydration stroke, as shown in FIG. Since the washing water is not drained in the open state, the sealing ball 520 located in the accommodating part 510 falls to the bottom due to its own weight, thereby blocking the drain pipe 400.

상기와 같은 상태에서 구동부의 구동에 의해 세탁조(200)가 일측방향으로 고속 회전되어 상기 세탁조의 회전원심력으로 인해 내부에 담겨져 있는 세탁물이 세탁조의 벽면에 밀착된 상태에서 세탁물에 침전되어 있는 세탁수의 탈수가 일어나 탈수된 세탁수가 배수관(400)을 통해 배수시 제2도b에 도시된 바와같이 배수되는 세탁수의 수압으로 인해 자중에 의해 배수관(400)을 밀폐시켜 주고 있던 밀폐볼(520)이 수용부(510)측으로 밀리면서 배수관이 열림에 따라 탈수되는 세탁수가 배수되는 것이며, 배수되는 세탁수에 의해 수용부(510)내에서 밀리는 밀폐볼(520)이 수용부의 선단부에 위치하고 있는 감지부(530)에 접지되므로서, 탈수되는 세탁수의 배수가 이루어짐을 감지하게 된다.In the above state, the washing tub 200 is rotated at a high speed in one direction by the driving of the driving unit, so that the laundry contained in the laundry tub is adhered to the wall of the washing tub, and the laundry is settled on the wall of the washing tub. When the dewatered washing water is drained through the drain pipe 400, the sealing ball 520 sealing the drain pipe 400 by its own weight due to the water pressure of the wash water drained as shown in FIG. Washing water which is dewatered as the drain pipe is opened while being pushed toward the receiving part 510 is drained, and the sensing part in which the sealing ball 520 pushed in the receiving part 510 by the drained washing water is located at the tip of the receiving part ( As it is grounded to 530, it is detected that the drainage of the washing water is dewatered.

상기와 같은 상태로 하여 탈수행정이 수행되다가 세탁물에 침전된 세탁수의 탈 수가 완료되면 구동부의 구동이 정지되어 탈수를 완료하게 되는데, 설정된 탈수시간전에 탈수행정이 완료되면 배수관(400)으로 배수되는 세탁수가 없으므로 인하여 배수되는 세탁수에 의해 수용부(510)측으로 밀려있던 밀폐볼(520)이 경사진 수용부(510)의 경사면에 의해 배수관(400)측으로 떨어져 감지부(530)로 부터 이격되면 구동부의 구동을 차단시켜 탈수행정을 정지시켜 주게되는 것이다.When the dehydration administration is performed in the above state and the dehydration of the wash water precipitated in the laundry is completed, the driving of the driving unit is stopped and the dehydration is completed. When the dehydration stroke is completed before the set dehydration time, the water is drained to the drain pipe 400. When the sealing ball 520 pushed toward the receiving part 510 by the washing water drained due to the absence of the washing water is dropped toward the drain pipe 400 by the inclined surface of the inclined receiving part 510, and is separated from the sensing part 530. It is to stop the dehydration stroke by blocking the drive of the drive.

이상에서와 같이 본 고안은 기히 설정된 탈수시간에 구애됨이 없이 탈수에 의해 배수되는 세탁수의 배수량을 감지하여 세탁수의 배수가 감지되지 않게되면 탈수가 완료된 것으로 인식하여 구동부의 구동을 정지시켜 주도록 되어있어 필요이상으로 탈수시간이 길어지게 되는 단점이 없으며 , 탈수행정시간동안 전원을 인가시켜 주므로 인해 전력의 사용량을 절약할수 있게되는 등의 효과가 있는 것이다.As described above, the present invention detects the drainage amount of the wash water drained by dehydration without being limited to the set dehydration time, and recognizes that the dehydration is completed when the drainage of the wash water is not detected. There is no disadvantage that the dehydration time becomes longer than necessary, and the power is applied during the dehydration administration time, thereby saving the power consumption.
