드럼세탁기의 세탁 제어방법How to control washing of drum washing machine

본 발명은 드럼세탁기에 관한 것으로, 특히 드럼세탁기의 저수조에 투입되는 세제를 세탁수에 충분히 용해시킨 다음 본 세탁을 수행하도록 함으로써 세탁효율을 향상시킬 수 있도록 한 드럼세탁기의 세탁 제어방법에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to a laundry control method for washing a drum washing machine, which is capable of improving washing efficiency by dissolving a detergent in a washing tank of a drum washing machine in washing water and then performing the main washing.

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 세탁운전을 실행하게 된다.In general, unlike the water-type washing machine that rotates the washing tank on the vertical axis to stir the laundry immersed in the washing water in the water tank by rotating the pulsator, the drum-type washing machine executes the washing operation by rotating the drum in which the laundry is put horizontally. Done.

따라서 드럼형 세탁기는 일반 저수조형 세탁기와는 다른 기계적인 구조를 가지게 된다.Therefore, the drum type washing machine has a mechanical structure different from that of the general water type washing machine.

도 1은 종래의 드럼세탁기의 개략적인 단면도로서, 세탁물(22)을 장입하고 있는 드럼(21) 둘레의 저수조(20)에는 일정수준까지의 수위(23)로 급수되어진 상태를 보이고 있다. 여기에서는, 드럼(21)이 회전하면 세탁수에 잠겨있던 세탁물(22)이 리프터(24)에 걸려 윗쪽으로 이동한 후 일정위치에 이르게 되면 자중에 의해 낙차되게 되며 이때의 낙차력으로 세탁이 이루어지도록 하고 있다.1 is a schematic cross-sectional view of a conventional drum washing machine, and shows a state in which the water tank 23 around the drum 21 in which the laundry 22 is charged is supplied with water level 23 up to a predetermined level. In this case, when the drum 21 rotates, the laundry 22, which has been locked in the wash water, is caught by the lifter 24 and moved upward, and when the drum 21 reaches a certain position, the laundry 22 drops by its own weight. To lose.

도 2는 종래의 드럼세탁기의 제어회로 구성도이다.2 is a block diagram illustrating a control circuit of a conventional drum washing machine.

여기에서 참고되는 바와 같이, 드럼세탁기의 전체 동작을 제어하게 되는 마이컴(10)에는 로드셀(11)에서 검출되는 세탁물의 중량값 변환 전기신호와, 저수조(20)내의 수위센서(19)에 의한 수위감지 신호가 입력되게 연결한다.As referred to herein, the microcomputer 10 that controls the overall operation of the drum washing machine includes a weight value conversion electric signal detected by the load cell 11 and a water level by the water level sensor 19 in the reservoir 20. Connect the sensing signal to input.

상기 마이컴(10)에서 처리되어 출력되는 급수제어 신호는 급수제어부(12)로 출력되게 연결하고, 상기 급수제어부(12)의 출력에 의해서는 급수밸브(13)가 작동되게 연결한다.The water supply control signal processed and output from the microcomputer 10 is connected to the water supply controller 12, and the water supply valve 13 is operatively connected by the output of the water supply controller 12.

상기 마이컴(10)에서 처리되어 출력되는 배수제어 신호는 배수제어부(14)로 출력되게 연결하고, 상기 배수제어부(14)의 출력에 의해서는 배수밸브(15)와 배수모터(16)가 작동되게 연결한다.The drain control signal processed and output from the microcomputer 10 is connected to the drain control unit 14, and the drain valve 15 and the drain motor 16 are operated by the output of the drain control unit 14. Connect.

상기 마이컴(10)에서 처리되어 출력되는 드럼 구동용 모터의 제어신호는 모터구동 제어부(17)로 출력되게 연결하고, 상기 모터구동 제어부(17)의 출력에 의해서는 드럼 모터(18)가 구동하게 연결한다.The control signal of the drum driving motor processed and output from the microcomputer 10 is connected to the motor driving control unit 17, and the drum motor 18 is driven by the output of the motor driving control unit 17. Connect.

이와 같이 구성된 드럼세탁기 제어회로의 동작과정을 설명하면 다음과 같다.Referring to the operation of the drum washing machine control circuit configured as described above are as follows.

먼저, 드럼세탁기의 도어를 열고 세탁물을 투입한 후 세탁운전 스타트 스위치를 온 시키면 드럼내에 투입된 세탁물의 중량은 로드셀(11)에 의해 검출된다. 이렇게 로드셀(11)에 의해 검출된 세탁물의 중량은 마이컴(10)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 weight of the laundry put into the drum is detected by the load cell 11. The weight of the laundry detected by the load cell 11 is input to the microcomputer 10.

이에 따라 마이컴(10)은 메모리 테이블을 참조하여 급수량을 결정하고 급수제어부(12)에 제어명령을 출력하여 급수밸브(13)가 열려지도록 함으로써 급수가 시작된다. 이렇게 급수가 진행되면 저수조의 일측에 마련된 수위센서(19)가 연속적으로 수위를 모니터링하여 그 검출 수위값을 마이컴(10)에 제공한다.Accordingly, the microcomputer 10 determines the water supply amount by referring to the memory table and outputs a control command to the water supply control unit 12 so that the water supply valve 13 is opened to start the water supply. As the water supply proceeds, the water level sensor 19 provided on one side of the water tank continuously monitors the water level and provides the detected water level value to the microcomputer 10.

상기 마이컴(10)은 입력되는 수위센서(19)로부터의 급수수위 검출신호를 받아들여 설정된 수위값에 도달하였는지 여부를 판단하여 급수수위값이 설정수위값에 도달하였으면 급수밸브 제어부(12)를 통해 급수밸브(13)를 차단하여 급수를 중단시킨다.The microcomputer 10 receives the input water level detection signal from the water level sensor 19 and determines whether the set water level value has been reached. The water supply is stopped by shutting off the water supply valve (13).

이렇게 드럼세탁기의 저수조에 세탁물에 대응하는 적정량의 세탁수가 저수 완료되고 나면 마이컴(10)은 내부의 세탁운전 프로그램에 따라 모터구동제어부(17)에 제어신호를 출력하여 모터(18)를 회전구동 시킨다.After the appropriate amount of wash water corresponding to the laundry is completed in the water tank of the drum washing machine, the microcomputer 10 outputs a control signal to the motor drive control unit 17 according to the internal washing operation program to rotate the motor 18. .

모터가 회전 구동하면 저수조(20)내의 세탁드럼(22)도 따라서 회전하게 되며 드럼 내부의 리프터(24)에 의한 세탁물의 순차이동 및 낙차를 이용한 세탁행정이 실행되게 된다.When the motor is driven to rotate, the washing drum 22 in the water storage tank 20 also rotates accordingly, and the washing stroke using the sequential movement and washing of the laundry by the lifter 24 inside the drum is executed.

그러나 종래의 세탁행정은 세탁수 상에 세제가 적절히 용해되었는지 여부에 상관없이 설정수위까지의 급수가 완료되면 바로 실행하도록 운전 프로그램이 설정되어 있어, 세제가 충분히 용해되지 못하고 뭉쳐져 있게 되는 경우에는 만족할 만한 세탁효과를 얻을 수 없게 되어있다.However, in the conventional washing administration, regardless of whether the detergent is properly dissolved in the washing water, the operation program is set to be executed immediately after the water supply up to the set level is completed, which is satisfactory when the detergent is not sufficiently dissolved and agglomerated. Washing effect is not obtained.

따라서 완전한 세탁을 위해서는 세탁행정 실행전에 저수조에 투입된 세제를 완전히 용해시키는 과정이 요망되고 있다.Therefore, in order to completely wash, it is desired to completely dissolve the detergent put into the reservoir before the washing administration.

본 발명의 목적은 드럼세탁기의 저수조에 투입되는 세제를 세탁수에 충분히 용해시키기 위해 드럼의 바깥쪽 둘레에 별도의 세제용해용 날개를 마련하여 이를 통하여 세탁수중의 세제가 빠른시간내에 완전히 용해될수 있도록 함으로써 세탁효과를 현저히 향상시킬 수 있도록 한 드럼세탁기의 세탁 제어방법을 제공하는데 있다.An object of the present invention is to provide a separate detergent dissolving wing to the outer periphery of the drum in order to dissolve the detergent in the water tank of the drum washing machine sufficiently to wash the detergent in the wash water quickly through this By providing a laundry control method of the drum washing machine to significantly improve the washing effect.

Connect.

이와 같이 구성된 드럼세탁기 제어회로를 기초로 하는 본 발명의 세탁 제어과정을 설명하면 다음과 같다.The washing control process of the present invention based on the drum washing machine control circuit configured as described above is as follows.

먼저, 드럼세탁기의 도어를 열고 세탁물을 투입한 후 세탁운전 스타트 스위치를 온 시키면 드럼내에 투입된 세탁물의 중량은 로드셀(11)에 의해 검출된다. 이렇게 로드셀(11)에 의해 검출된 세탁물의 중량은 마이컴(10)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 weight of the laundry put into the drum is detected by the load cell 11. The weight of the laundry detected by the load cell 11 is input to the microcomputer 10.

이에 따라 마이컴(10)은 메모리 테이블을 참조하여 급수량을 결정하고 급수제어부(12)에 제어명령을 출력하여 급수밸브(13)가 열려지도록 함으로써 급수가 시작된다. 이렇게 급수가 진행되면 저수조의 일측에 마련된 수위센서(19)가 연속적으로 수위를 모니터링하여 그 검출 수위값을 마이컴(10)에 제공한다.Accordingly, the microcomputer 10 determines the water supply amount by referring to the memory table and outputs a control command to the water supply control unit 12 so that the water supply valve 13 is opened to start the water supply. As the water supply proceeds, the water level sensor 19 provided on one side of the water tank continuously monitors the water level and provides the detected water level value to the microcomputer 10.

상기 마이컴(10)은 입력되는 수위센서(19)로부터의 급수수위 검출신호를 받아들여 설정된 수위값에 도달하였는지 여부를 판단하여 급수 수위값이 설정 수위값에 도달하였으면 급수밸브 제어부(12)를 통해 급수밸브(13)를 차단하여 급수를 중단시킨다.The microcomputer 10 receives the input water level detection signal from the water level sensor 19 and determines whether the water level has reached the set level value. The water supply is stopped by shutting off the water supply valve (13).

이후 세탁행정의 실행에 앞서 마이컴(10)은 세제농도센서(26)를 통하여 세탁수중에 용해된 세제농도 값을 읽어들인 다음, 이 값을 설정수위에 대한 적정 세제량 투입시의 농도값을 기준으로 하는 기준값에 비교하게 된다.Thereafter, before executing the washing administration, the microcomputer 10 reads the detergent concentration value dissolved in the washing water through the detergent concentration sensor 26, and then sets this value based on the concentration value at the time of inputting the appropriate detergent amount for the set water level. To a reference value.

그 실행과정을 도 3의 흐름도에 나타내고 있다. 여기에서 참고되는 바와 같이, 급수완료후 세제농도센서에 의해 검출된 세탁수의 세제농도가 적정농도에 이르지 못한 것으로 판단되면 마이컴은 세제의 용해가 불충분한 상태로 판단하고 정해진 프로그램에 따라 세탁 드럼을 회전시킨다.The execution process is shown in the flowchart of FIG. As referred to herein, if it is determined that the detergent concentration of the wash water detected by the detergent concentration sensor after the completion of the water supply does not reach the proper concentration, the microcomputer determines that the detergent is insoluble and the washing drum according to the predetermined program. Rotate

상기 정해진 프로그램은 드럼 구동시간을 기준으로 할 수 있고 또한 드럼 회전횟수를 기준으로 할 수 있다.The predetermined program may be based on the drum driving time and may also be based on the drum rotation frequency.

드럼의 회전은 그의 바깥쪽 둘레에 마련된 세제용해용 날개에 의해 세탁 수류를 빠르게 이동시켜주게 되므로 용해되지 않은 세제의 신속한 용해를 돕는다.Rotation of the drum facilitates rapid dissolution of the undissolved detergent, as the washing water flow is quickly moved by the detergent dissolving blades provided around its outer circumference.

이렇게하여 세제용해를 위한 드럼회전 과정이 수행되고 난 다음에는 다시 세제농도를 센싱하여 그 용해도가 적정한 값인가 여부를 다시 판단한다. 이와 같은 식으로 세탁수중의 세제용해를 신속화시켜 적정 세제용해 농도값이 얻어지면 마이컴은 세탁행정모드를 진행하게 된다.In this way, after the drum rotation process for detergent dissolution is performed, the detergent concentration is sensed again to determine whether the solubility is an appropriate value. In this manner, when the detergent dissolution in the washing water is accelerated to obtain an appropriate detergent dissolution concentration value, the microcomputer proceeds to the washing administration mode.

이러한 드럼세탁운전중 세탁수 중의 세제용해 제어과정을 단계별로 요약 하면 다음과 같다.The detergent dissolution control process in the wash water during the drum washing operation is summarized as follows.

제1단계에서는 세탁조에 투입된 부하량의 센싱을 통하여 수위를 결정한후 세제투입 및 급수를 실행한다.In the first step, the water level is determined by sensing the load amount put into the washing tank, and then detergent input and water supply are executed.

제2단계에서는 상기 제1단계의 급수실행 완료후 세제농도센서를 이용하여 세탁수의 농도를 센싱한다.In the second step, the concentration of the washing water is sensed using the detergent concentration sensor after the water supply execution of the first step is completed.

제3단계에서는 상기 제2단계에서 센서에 의해 센싱된 세제의 농도가 적정농도가 아니면 일정시간 동안 드럼을 회전시켜 세제용해를 실시한후 세제농도의 재검출을 실행하고 센싱된 농도가 적정농도이면 세탁루틴을 통한 일련의 세탁과정을 실행한다.In the third step, if the concentration of the detergent sensed by the sensor in the second step is not the proper concentration, the drum is rotated for a predetermined time to dissolve the detergent, and the detergent concentration is redetected. Run a series of washing routines through routines.

이상에서 설명한 바와 같은 본 발명은 드럼세탁기에서의 세탁운전 개시에 앞서 급수된 세탁수 중의 세제농도가 적정한지 여부를 판단하여 세탁수중의 세제농도가 기준값에 미달하게 되는 경우 세제용해 프로그램에 따라 세제용해날개를 가지는 드럼을 회전시켜줌으로써 세탁수 중의 세제용해 농도를 빠른시간내에 적정화시켜 주게 되므로, 세제뭉침에 따른 불완전 세탁을 방지할 수 있게 되는 특유의 효과가 나타나게 된다.As described above, the present invention is to determine whether the detergent concentration in the wash water supplied before the start of the washing operation in the drum washing machine to determine whether the detergent concentration in the wash water is less than the reference value detergent detergent dissolution according to the detergent dissolution program By rotating the drum with the blades to optimize the detergent dissolution concentration in the wash water in a short time, the unique effect of preventing the incomplete washing due to the detergent bundle appears.
