드럼세탁기의 탈수운전 방법{METHOD FOR DRIVING DEHYDRATION OF DRUM WASHER}Dehydration operation method of drum washing machine {METHOD FOR DRIVING DEHYDRATION OF DRUM WASHER}

본 발명은 드럼세탁기의 탈수운전 방법에 관한 것으로서, 보다 상세하게는 드럼세탁기에서 본탈수를 진행하기 전 세탁물의 균형을 잡기 위한 밸런스 탈수시 본탈수 진입을 실패할 경우 언밸런스값을 순차적으로 상승시키면서 밸런스 탈수를 진행하여 본탈수 진입율을 향상시킬 수 있도록 한 드럼세탁기의 탈수운전 방법에 관한 것이다.
The present invention relates to a dehydrating operation method of a drum washing machine, and more particularly, to balance the laundry before proceeding with the main dehydration in the drum washing machine, when the dehydration of the main dehydration in the case of failure in entering the main dehydration during balance dehydration while increasing the balance sequentially The present invention relates to a dehydration operation method of a drum washing machine that allows dehydration to improve the main dehydration entry rate.

일반적으로 수직축 상에서 세탁조를 회전시키는 저수조형 세탁기가 펄세이터의 회전구동을 통하여 저수조 내의 세탁수에 잠겨진 세탁물을 교반 세탁하는 것과는 달리 드럼형 세탁기는 세탁물이 투입된 드럼을 수평회전시키는 동작으로 세탁물을 이동시킨 후 떨어지는 낙차력과 회전하는 드럼과 세탁물간의 마찰을 이용하여 세탁하는 것으로 세탁물의 손상이 거의 없고 세탁물이 서로 엉키지 않으며 두드리고 비벼 빠는 세탁효과가 있다. In general, unlike the water-type washing machine which rotates the washing tank on the vertical axis, the washing machine is agitated to wash the laundry immersed in the washing water in the water tank by rotating the pulsator. After washing by using the falling power of falling and the friction between the rotating drum and the laundry, there is almost no damage to the laundry and the laundry is not tangled with each other, there is a laundry effect of pounding and scuffing.

도 1은 일반적인 드럼세탁기를 개략적으로 나타낸 단면도이다. 1 is a cross-sectional view schematically showing a general drum washing machine.

여기에 도시된 바와 같이 세탁물(14)을 장입하고 있는 드럼(11) 둘레의 저수조(10)에는 일정수준까지의 수위(15)로 급수되어진 상태를 보이고 있다. 여기에서는, 드럼(11)이 회전하면 세탁수에 잠겨있던 세탁물(14)이 리프터(12)에 걸려 윗쪽으로 이동한 후 일정위치에 이르게 되면 자중에 의해 낙차되게 되며 이때의 낙차력으로 세탁이 이루어지도록 하고 있다.As shown here, the reservoir 10 around the drum 11, which is loaded with the laundry 14, shows a state in which water is supplied to the water level 15 up to a predetermined level. In this case, when the drum 11 rotates, the laundry 14, which is locked in the washing water, is caught by the lifter 12 and moved upward, and when the drum 11 reaches a predetermined position, the drum 11 is dropped by its own weight. To lose.

또한, 드럼(11) 하부에는 세탁수를 가열하기 위한 세탁히터(13)가 설치되어 삶아 빠는 세탁효과를 얻을 수 있도록 하고 있다. In addition, a washing heater 13 for heating the washing water is installed at the lower part of the drum 11 so as to obtain a washing effect of boiling.

도 2는 일반적인 드럼세탁기의 제어회로를 나타낸 블록구성도이다. 2 is a block diagram showing a control circuit of a general drum washing machine.

여기에 도시된 바와 같이 드럼(11) 내에 장입된 세탁물(14)의 중량값을 측정하기 위한 로드셀센서(21)와, 저수조(10) 내의 세탁수의 수위를 감지하기 위한 수위센서(29)와, 로드셀센서(21)와 수위센서(29)의 값을 입력받아 드럼세탁기의 전체동작을 제어하기 위한 마이컴(20)과, 마이컴(20)의 급수 제어신호에 따라 급수밸브의 작동을 제어하기 위한 급수제어부(22)와, 마이컴(20)의 배수 제어신호에 따라 배수밸브(25)와 배수모터(26)의 작동을 제어하기 위한 배수제어부(24)와, 마이컴(20)의 모터 제어신호에 따라 드럼(11)을 회전시키기 위한 모터(28)의 작동을 제어하기 위한 모터구동제어부(27)와, 마이컴(20)의 제어신호에 따라 세탁수를 가열하기 위한 세탁히터(13)로 이루어진다. As shown here, the load cell sensor 21 for measuring the weight value of the laundry 14 loaded in the drum 11, the water level sensor 29 for detecting the water level of the wash water in the reservoir 10 and For receiving the values of the load cell sensor 21 and the water level sensor 29, the microcomputer 20 for controlling the overall operation of the drum washing machine and the water supply control signal of the microcomputer 20 for controlling the operation of the water supply valve. In response to the water supply control unit 22, the drain control unit 24 for controlling the operation of the drain valve 25 and the drain motor 26 in accordance with the drain control signal of the microcomputer 20, and the motor control signal of the microcomputer 20 Accordingly, the motor driving control unit 27 for controlling the operation of the motor 28 for rotating the drum 11, and the laundry heater 13 for heating the wash water in accordance with the control signal of the microcomputer 20.

이와 같이 구성된 드럼세탁기의 동작을 설명하면 다음과 같다. Referring to the operation of the drum washing machine configured as described above are as follows.

먼저, 드럼세탁기의 도어를 열고 세탁물을 투입한 후 세탁운전 스타트 스위치를 온 시키면 드럼(11) 내에 투입된 세탁물(14)의 중량을 로드셀센서(21)에 의해 검출된다. 이렇게 로드셀센서(21)에 의해 검출된 세탁물의 중량은 마이컴(20)에 입력된다.First, when the door of the drum washing machine is opened and the laundry is put in and the washing operation start switch is turned on, the load cell sensor 21 detects the weight of the laundry 14 put into the drum 11. The weight of the laundry detected by the load cell sensor 21 is input to the microcomputer 20.

이에 따라 마이컴(20)은 메모리 테이블을 참조하여 급수량을 결정하고 급수제어부(22)에 제어명령을 출력하여 급수밸브(23)가 열려지도록 함으로써 급수가 시작된다. 이렇게 급수가 진행되면 저수조(20)의 일측에 마련된 수위센서(29)에 의해 수위를 모니터링하여 그 검출수위값을 마이컴(20)에 제공한다. 그러면, 마이컴(20)은 입력되는 수위센서(29)로부터의 검출수위값을 통해 설정된 수위값에 도달하였는지 여부를 판단하여 검출수위값이 설정수위값에 도달하였으면 급수제어부(22)를 통해 급수밸브(23)를 차단하여 급수를 중단시킨다.Accordingly, the microcomputer 20 determines the water supply amount with reference to the memory table and outputs a control command to the water supply control unit 22 so that the water supply valve 23 is opened to start the water supply. When the water supply proceeds as described above, the water level is monitored by the water level sensor 29 provided at one side of the reservoir 20, and the detected water level value is provided to the microcomputer 20. Then, the microcomputer 20 determines whether the set water level value is reached based on the detected water level value from the input water level sensor 29. When the detected water level value reaches the set water level value, the water supply valve 22 supplies the water supply valve. Shut off (23) to stop water supply.

이렇게 드럼세탁기의 저수조(20)에 세탁물(14)에 대응하는 적정량의 세탁수가 저수 완료되고 나면 마이컴(20)은 내부의 세탁운전 프로그램에 따라 모터구동제어부(27)에 제어신호를 출력하여 모터(28)를 회전구동 시킨다. After the appropriate amount of washing water corresponding to the laundry 14 is stored in the water storage tank 20 of the drum washing machine, the microcomputer 20 outputs a control signal to the motor driving control unit 27 according to the internal washing operation program to supply the motor ( Rotate 28).

모터(28)가 회전 구동하면 저수조(20)내의 세탁 드럼(11)도 따라서 회전하게 되며 드럼(11) 내부의 리프터(12)에 의한 세탁물의 순차이동 및 낙차를 이용한 드럼세탁이 실행되게 된다.When the motor 28 is driven to rotate, the washing drum 11 in the reservoir 20 also rotates accordingly, and the drum washing using the sequential movement and washing of the laundry by the lifter 12 inside the drum 11 is performed.

이와 같이 세탁운전을 완료한 후에는 세탁물(14)에 포함된 세탁수를 제거하기 드럼(11)을 고속회전시켜 원심력에 의한 탈수운전을 수행하게 된다. After the washing operation is completed as described above, the drum 11 is rotated at a high speed to remove the washing water contained in the laundry 14, and the dehydration operation is performed by centrifugal force.

이렇게 탈수되는 물은 드럼(11) 원주벽에 형성된 수많은 미세한 구멍을 통해 저수조(20)로 빠져나오면 배수밸브(25)와 배수모터(26)가 작동되어 밖으로 배수된다.
The dewatered water is discharged to the reservoir 20 through a number of fine holes formed in the circumferential wall of the drum 11 so that the drain valve 25 and the drain motor 26 are drained out.

위에서 설명한 기술은 본 발명이 속하는 기술분야의 배경기술을 의미하며, 종래기술을 의미하는 것은 아니다.
The technology described above refers to the background of the technical field to which the present invention belongs, and does not mean the prior art.

이와 같이 세탁운전 및 헹굼운전을 마친 후 탈수운전을 수행하기 위해서는 먼저, 밸런스 탈수를 수행하여 세탁물을 좌우 교반운전을 통해 뭉쳐있는 포를 펼친 후 일정한 속도로 회전시켜 포를 드럼 내벽에 골고루 붙여 가속하여 언밸런스를 판단한 후 언밸런스값이 설정값 이하일 경우 본탈수를 진행하게 된다. In order to perform the dehydration operation after the washing operation and the rinsing operation as described above, first, the balance dehydration is performed to spread the bundles of laundry through left and right stirring operation, and then rotated at a constant speed to accelerate the cloth evenly by attaching it to the inner wall of the drum. After determining the unbalance, if the unbalance value is less than the set value, the main dehydration proceeds.

그런데, 밸런스 탈수를 설정횟수 시도하고도 언밸런스값이 설정값을 만족시키기 못하게 되면 탈수진입 에러를 표시하고 탈수를 진행하지 않게 됨에 따라 탈수진입 시간이 길어질 뿐만 아니라 반복적인 밸런스 탈수를 통해 전력소비가 많아 전력낭비가 발생되는 문제점이 있다. However, if the unbalanced value does not satisfy the set value even after the number of attempts to set the balance dehydration, the dehydration entry error is displayed and the dehydration entry time becomes longer as the dehydration does not proceed, and the power consumption is increased through repetitive balance dehydration. There is a problem that a power waste occurs.

또한, 탈수진입을 실패할 경우 세탁기를 잠시 자리를 비운 후 돌아왔을 때 세탁이 완료되지 않게 됨에 따라 소비자의 불만이 야기되는 문제점이 있다. In addition, there is a problem that when the dehydration entry fails, the laundry is not completed when the washing machine is returned after leaving the seat for a while, causing consumer complaints.

본 발명은 상기와 같은 문제점을 개선하기 위해 창작된 것으로서, 드럼세탁기에서 본탈수를 진행하기 전 세탁물의 균형을 잡기 위한 밸런스 탈수시 본탈수 진입을 실패할 경우 언밸런스값을 순차적으로 상승시키면서 밸런스 탈수를 진행하여 본탈수 진입율을 향상시킬 수 있도록 한 드럼세탁기의 탈수운전 방법을 제공하는데 그 목적이 있다. The present invention was created to improve the above problems, when dehydration of the balance in order to balance the laundry before proceeding to the main dehydration in the drum washing machine unbalanced while dehydrating the balance while increasing the unbalance value sequentially The purpose of the present invention is to provide a dehydration operation method of a drum washing machine that can improve the main dehydration entry rate.

또한, 본 발명은 밸런스 탈수에서 본탈수 진입을 실패할 경우 본탈수의 회전속도를 낮추어 저속탈수를 진행하는 드럼세탁기의 탈수운전 방법을 제공하는데 그 목적이 있다.
In addition, an object of the present invention is to provide a dehydration operation method of a drum washing machine that lowers the rotation speed of the main dehydration when the main dehydration entry fails in the balance dehydration.

본 발명의 일 측면에 따른 드럼세탁기의 탈수운전 방법은 밸런스 탈수를 진행하면서 언밸런스값을 검출하는 제 1단계; 언밸런스값과 설정값을 비교하여 설정값 이하일 경우 본탈수를 진행하는 제 2단계; 언밸런스값과 설정값을 비교하여 설정값을 초과할 경우 설정값을 상향조정한 후 제 1단계로 리턴하는 제 3단계; 및 제 3단계에서 제 1단계로 리턴된 반복횟수가 설정횟수를 초과할 경우 에러를 표시하는 제 4단계를 포함하는 것을 특징으로 한다. Dehydration operation method of the drum washing machine according to an aspect of the present invention comprises a first step of detecting an unbalance value while the balance dehydration proceeds; A second step of comparing the unbalance value with the set value and performing dehydration if the set value is less than the set value; A third step of comparing the unbalanced value with the set value and increasing the set value and returning to the first step if the set value is exceeded; And a fourth step of displaying an error when the number of repetitions returned from the third step to the first step exceeds the set number of times.

본 발명은 제 4단계에서 에러를 표시한 후 저속탈수를 진행하는 단계를 더 포함하는 것을 특징으로 한다. The present invention is characterized in that it further comprises the step of proceeding the slow dehydration after displaying the error in the fourth step.

본 발명은 제 3단계에서 설정값을 상향조정할 때 이전 설정값에서 10% 상승시키는 것을 특징으로 한다. The present invention is characterized in that to increase the set value 10% from the previous set value when the set value is increased in the third step.

본 발명은 제 3단계에서 설정값을 상향조정할 때 밸런스 탈수의 각 구간별로 언밸런스값이 설정값을 초과한 구간에 대해 설정값을 상향조정하는 것을 특징으로 한다.
The present invention is characterized in that when the value is adjusted upward in the third step, the setting value is adjusted upward for the section in which the unbalanced value exceeds the setting value for each section of the balance dehydration.

상기한 바와 같이 본 발명은 드럼세탁기에서 본탈수를 진행하기 전 세탁물의 균형을 잡기 위한 밸런스 탈수시 본탈수 진입을 실패할 경우 언밸런스값을 순차적으로 상승시키면서 밸런스 탈수를 진행하여 밸런스 탈수의 반복횟수를 줄일 수 있을 뿐만 아니라 본탈수 진입율을 향상시킬 수 있으며, 본탈수 진입을 실패할 경우 본탈수의 회전속도를 낮추어 저속탈수를 진행하여 탈수운전을 완료할 수 있도록 한다.
As described above, the present invention proceeds to balance dehydration while sequentially increasing the unbalance value when the balance dehydration fails to enter the main dehydration to balance the laundry before proceeding to the main dehydration in the drum washing machine to repeat the number of repetitions of the balance dehydration. Not only can it be reduced, but it can also improve the rate of entry of the main dehydration, and if the main dehydration fails to enter, the rotational speed of the main dehydration is lowered so that the dehydration operation can be completed by performing the low speed dehydration.

In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

도 3은 본 발명의 일 실시예에 따른 드럼세탁기의 탈수운전 방법을 설명하기 위한 흐름도이고, 도 4는 본 발명의 일 실시에에 따른 드럼세탁기의 탈수운전 과정을 나타낸 그래프이다. 3 is a flowchart illustrating a dehydration operation method of a drum washing machine according to an embodiment of the present invention, and FIG. 4 is a graph showing a dehydration operation process of the drum washing machine according to an embodiment of the present invention.

도 3에 도시된 바와 같이 본 발명의 일 실시예에 따른 드럼세탁기의 탈수운전은 세탁운전과 헹굼운전을 종료한 후 탈수운전에 진입하게 되면 먼저 밸런스 탈수를 진행한다(S10). As shown in Figure 3, the dehydration operation of the drum washing machine according to an embodiment of the present invention proceeds to the balance dehydration after entering the dehydration operation after ending the washing operation and the rinsing operation (S10).

밸런스 탈수는 도 4에 도시된 바와 같이 포붙임 구간과 상승구간으로 구분하여 포붙임 구간에서 언밸런스값을 만족할 경우 상승구간으로 진입하게 되고, 상승구간에서 언밸런스값을 만족할 경우 본탈수로 진입하게 된다. As shown in FIG. 4, the balance dehydration is divided into a catching section and a rising section and enters the rising section when the unbalanced value is satisfied in the embedding section, and enters the main dehydration when the unbalanced value is satisfied in the rising section.

이와 같이 밸런스 탈수를 진행하면서 언밸런스값을 검출한다(S12). In this way, the unbalanced value is detected while the balance is dewatered (S12).

이후 검출된 언밸런스값을 설정값과 비교한다(S140). Thereafter, the detected unbalanced value is compared with the set value (S140).

이때 언밸런스값이 설정값 이하일 경우에는 본탈수를 진행한다(S16). At this time, if the unbalance value is less than the set value, the main dehydration proceeds (S16).

그러나, 언밸런스값이 설정값을 초과할 경우에는 설정값을 약 10% 정도 상향조정한다(S18). However, if the unbalanced value exceeds the set value, the set value is increased by about 10% (S18).

이때 밸런스 탈수의 각 구간별로 설정값을 상향조정할 수도 있다. At this time, the set value may be adjusted upward for each section of the balance dehydration.

즉, 포붙임 구간에서의 언밸런스값은 설정값 이하였으나 상승구간에서 언밸런스값이 설정값을 초과할 경우 상승구간에서의 언밸런스 설정값만을 상향조정할 수도 있으며, 모든 구간에 대해 설정값을 상향조정할 수도 있다. In other words, if the unbalanced value in the overlapping section is less than the set value but the unbalanced value exceeds the set value in the rising section, only the unbalanced setting value in the rising section may be adjusted upward, or the setting value may be increased for all sections. .

이와 같이 언밸런스 설정값을 상향조정한 후 밸런스 탈수를 다시 진행하면서 언밸런스값을 검출하여 설정값과 비교하는 과정을 반복한다(S20). As described above, the process of detecting the unbalanced value and comparing it with the set value is repeated while the balance is dehydrated after the unbalanced set value is adjusted upward (S20).

이때 검출된 언밸런스값이 설정값 이하일 경우에는 본탈수를 진행하게 된다. At this time, if the detected unbalance value is less than the set value, the main dehydration is performed.

이러한 반복횟수가 설정횟수를 초과할 경우 밸런스 탈수 에러를 표시하게 된다(S22). If the number of repetitions exceeds the set number of times, a balance dehydration error is displayed (S22).

이후 밸런스 탈수 에러가 발생하게 될 경우 본탈수의 RPM보다 낮은 저속탈수를 통해 탈수를 진행하여 탈수운전을 종료할 수도 있다(S24). Then, if a balance dehydration error occurs, the dehydration operation may be terminated by proceeding with dehydration through a low speed dehydration lower than the RPM of the main dehydration (S24).

예를들어, 밸런스 탈수를 10회 반복하고도 언밸런스값이 설정값을 초과할 경우 밸런스 탈수 에러를 표시할 뿐만 아니라 500RPM의 저속탈수를 진행하고 탈수운전을 종료하게 된다. For example, if the unbalanced value exceeds the set value even after 10 times of dehydration of the balance, the balance dehydration error is displayed and the low speed dehydration of 500 RPM is performed and the dehydration operation is terminated.

이와 같이 언밸런스 설정값을 상향조정함으로써 전체적인 밸런스 탈수의 반복횟수를 줄여 전력소모를 줄일 뿐만 아니라 본탈수 진입율을 향상시키게 된다.
In this way, by increasing the unbalance setting value, the number of repetitions of the balance dehydration is reduced, thereby reducing the power consumption and improving the main dehydration entry rate.
