그리고, 상기 탈수조(7)내에는 탈수조(7)내에 저장되어 있는 세탁수에 수류를 형성시켜 세탁물을 세탁 및 탈수하는 펄세이터(9)가 설치되어 있고, 상기 세탁조(5)의 저면에는 상기 펄세이터(9) 및 탈수조(7)를 회전시키도록 구동하는 세탁모터(11)가 설치되어 있고, 상기 세탁모터(11)의 일측에는 세탁모터(11)의 구동력을 벨트(13)를 통해 전달받아 상기 탈수조(7) 및 펄세이터(9)를 구동시키는 동력전달장치(15)가 설치되어 있다.The dehydration tank 7 is provided with a pulsator 9 for washing and dehydrating laundry by forming a stream of water in the wash water stored in the dehydration tank 7, and at the bottom of the washing tank 5. The washing motor 11 is driven to rotate the pulsator 9 and the dehydration tank 7. The driving force of the washing motor 11 is applied to one side of the washing motor 11. Received through the power transmission device 15 for driving the dehydration tank (7) and the pulsator (9) is installed.

또한, 상기 본체(1)의 상부에는 상기 세탁조(5)내에 세탁수를 급수하는 급수수단(17)이 설치되어 있고, 상기 급수수단(17)의 일측에는 분말세제를 용해시킴과 동시에 정전기방지나 세탁물에 유연성 등을 부여하는 유연제를 공급하는 세제용해기(19)가 설치되어 있으며, 상기 세탁조(5)의 하부면에는 세탁 및 헹굼시 오염된 세탁수를 배수호스(23)를 통해 배출하는 배수밸브(21)가 설치되어 있다.In addition, a water supply means 17 for supplying the washing water in the washing tank 5 is provided on the upper portion of the main body 1, and one side of the water supply means 17 dissolves powder detergent and prevents static electricity. A detergent dissolving device (19) is provided to supply a softening agent to impart flexibility to laundry, and the lower surface of the washing tank (5) drains contaminated washing water through a drain hose (23) during washing and rinsing. The valve 21 is provided.

상기와 같이 구성된 종래의 세탁기에 있어서, 먼저 사용자가 탈수조(7)내에 세탁물을 투입한다음 원하는 세탁조건을 입력하고 운전버튼을 온시키면, 급수수단(17)을 통해 온수 또는 냉수의 세탁수가 세제용해기(19)를 거쳐 용해된 세제와 함께 세탁조(5)내에 급수된다.In the conventional washing machine configured as described above, when the user first puts laundry into the dehydration tank 7 and then inputs the desired washing condition and turns on the operation button, the washing water of hot or cold water is supplied through the water supply means 17. The water is supplied into the washing tank 5 together with the detergent dissolved through the dissolver 19.

상기 세탁조(5)내에 세탁수가 급수됨에 따라 밀폐된 호스(도시안됨)를 통해 압력이 상승하면 수위센서(도시안됨) 내부에 있는 주파수 발진회로의 주파수가 낮아지므로 이때의 변화하는 주파수를 판독하여 세탁수의 수위를 결정한다.If the pressure rises through the sealed hose (not shown) as the wash water is supplied to the washing tank 5, the frequency of the frequency oscillation circuit inside the water level sensor (not shown) is lowered, so that the washing frequency is read and washed. Determine the water level.

상기 세탁조(5)내에 급수된 세탁수가 결정된 세탁수위만큼 급수완료되면, 세탁모터(11)의 구동에 의한 회전력이 벨트(13)를 통해 동력전달장치(15)에 전달되고, 상기 동력전달장치(15)에 전달된 세탁모터(11)의 회전력에 의해 펄세이터(9)가 좌우반전되면서 급수된 세탁수에 수류를 형성시킨다.When the wash water supplied to the washing tank 5 is completed by the determined washing water level, the rotational force driven by the driving of the washing motor 11 is transmitted to the power transmission device 15 through the belt 13, the power transmission device ( The pulsator 9 is reversed left and right by the rotational force of the washing motor 11 transmitted to 15) to form a water stream in the wash water supplied.

상기 펄세이터(9)의 좌우반전에 따라 형성되는 수류는 세탁수에 압력을 가하게 됨으로써 세탁물에 흡착된 때나 이물질 등을 분리시켜 세탁이 이루어진다.The water flow formed along the left and right inversion of the pulsator 9 is applied to the wash water to separate the adsorbed laundry or foreign matters to wash.

상기 세탁모터(11)의 구동에 따라 세탁이 이루어지면, 배수밸브(21)의 개방에 따라 세탁조(5)내의 오염된 물이 배수호스(23)를 통해 외부로 배출되고, 이어서 세탁모터(11)를 구동시켜 세탁물을 간헐적으로 탈수하는 간헐탈수공정을 수행한다음 헹굼행정을 수행하기위해 급수수단(17)을 통해 세탁수(헹굼수)가 세탁조(5)내에 급수되어 상기 세탁조(5)내에 급수된 세탁수가 결정된 세탁수위만큼 급수완료되면, 세탁모터(11)의 구동에 따라 펄세이터(9)가 좌우반전되면서 세탁수에 수류를 형성시켜 헹굼을 수행한다.When washing is performed by driving the washing motor 11, contaminated water in the washing tank 5 is discharged to the outside through the drain hose 23 according to the opening of the drain valve 21, and then the washing motor 11. To perform the intermittent dehydration process of dehydrating the laundry intermittently, and then the washing water (rinsing water) is supplied into the washing tank 5 through the water supply means 17 to perform the rinsing stroke, and then into the washing tank 5. When the water supplied to the washing water is completed by the determined washing water level, the pulsator 9 is reversed left and right according to the driving of the washing motor 11 to form a water stream in the washing water to rinse.

헹굼을 수회 수행하면, 배수밸브(21)의 개방에 따라 세탁조(5)내의 헹굼수가 배수호스(23)를 통해 외부로 배출되고, 세탁모터(11)의 구동에 따라 탈수조(7)가 한쪽방향으로 고속회전하면서 발생된 원심력에 의해 세탁물의 탈수가 이루어져 전체세탁행정을 완료한다.When the rinsing is performed several times, the rinsing water in the washing tank 5 is discharged to the outside through the drain hose 23 as the drain valve 21 is opened, and the dehydrating tank 7 is driven by one side of the washing motor 11. The laundry is dewatered by the centrifugal force generated at high speed in the direction to complete the entire washing process.

그런데, 이와같은 종래의 세탁기에 있어서는, 세탁물의 양(부하량)이나 세탁물의 종류(포질)에 따라 흡수하는 세탁수의 양이 다름에도 불구하고 세탁물의 양이나 종류에 관계없이 주파수에 의해 결정된 세탁수위만큼 무조건 급수하므로 필요이상의 급수동작으로 에너지낭비와 세탁수가 낭비된다는 문제점이 있었다.By the way, in such a conventional washing machine, the washing water level determined by the frequency irrespective of the amount or type of laundry despite the difference in the amount of wash water absorbed according to the amount of laundry (load) or the type of laundry (form). As there is no water supply condition, there is a problem that waste of energy and washing water are wasted due to more water supply than necessary.

따라서, 본 발명은 상술한 종래의 문제점을 해결하기 위하여 안출된 것으로, 급수동작시 세탁모터를 일정시간마다 회전시켜 모터회전수를 감지하고 모터회전수가 일정RPM에 도달하면 급수동작을 중지하여 세탁수량을 결정하므로 세탁수위를 세탁물의 양과 종류에 맞게 최적으로 제어하여 에너지를 절감하고, 세탁수의 낭비를 방지하는 세탁기의 수위제어방법을 제공하는데 그 목적이 있다.Therefore, the present invention has been made in order to solve the above-mentioned problems, the rotation of the washing motor at a predetermined time during the water supply operation to detect the motor rotational speed and stop the water supply operation when the motor rotational speed reaches a certain RPM, the amount of washing water Therefore, the purpose of the present invention is to provide a method for controlling the level of a washing machine to reduce energy by controlling the washing level according to the amount and type of laundry, and to prevent waste of washing water.

도 2에 도시한 바와같이, 세탁모터(11)의 축에 배설된 풀리(12)의 양측끝단에는 상기 세탁모터(11)의 구동시에 회전하는 두 개의 마그네트(25)가 설치되어 있고, 상기 마그네트(25)와 소정간격을 두고 상기 세탁모터(11)의 하부 소정위치에는 세탁모터(11)의 회전수를 감지하도록 상기 세탁모터(11)의 구동시에 회전하는 마그네트(25)와 교차함에 따라 상기 마그네트(25)의 극수를 감지하여 세탁모터(11)의 회전수에 비례하는 펄스를 발생하는 홀센서(27)가 설치되어 있다.As shown in FIG. 2, two magnets 25 rotating at the time of driving the washing motor 11 are provided at both ends of the pulley 12 disposed on the shaft of the washing motor 11. The predetermined position at the lower portion of the washing motor 11 at a predetermined interval with the (25) to intersect with the magnet 25 that rotates during the driving of the washing motor 11 to detect the rotational speed of the washing motor 11 The hall sensor 27 for detecting the number of poles of the magnet 25 and generating a pulse proportional to the rotational speed of the washing motor 11 is provided.

한편, 상기 홀센서(27)는 홀센서(27)에 의해 감지된 회전수신호를 후술하는 제어수단에 출력하는 홀센서PCB와 도시되지 않은 케이스내에 일체로 내장되어 있다.On the other hand, the Hall sensor 27 is integrally embedded in the case and the Hall sensor PCB for outputting the rotational speed signal sensed by the Hall sensor 27 to the control means to be described later.

다음에는, 도 3을 참조하여 세탁기의 수위제어회로에 관하여 설명한다.Next, the water level control circuit of the washing machine will be described with reference to FIG. 3.

도 3에 도시한 바와같이, 전원수단(100)은 도시되지 않은 교류전원단으로부터 공급되는 상용교류전압을 상기 세탁기의 동작에 필요한 소정의 직류전압으로 변환하여 각 구동회로에 출력하고, 운전조작수단(102)은 사용자가 원하는 세탁조건(세탁종류, 세탁시간, 급수선택 등)을 입력하도록 도어(3)의 소정위치에 다수의 기능버튼을 구비하고 있다.As shown in FIG. 3, the power supply means 100 converts a commercial AC voltage supplied from an AC power supply terminal (not shown) into a predetermined DC voltage required for the operation of the washing machine, and outputs it to the respective driving circuits. 102 is provided with a plurality of function buttons at a predetermined position of the door 3 to input a washing condition (washing type, washing time, water supply selection, etc.) desired by the user.

제어수단(104)은 상기 전원수단(100)으로부터 출력되는 직류전압을 인가받아 세탁기를 초기화시킴은 물론, 상기 운전조작수단(102)에 의해 입력된 운전명령신호에 따라 상기 세탁기의 전체적인 동작을 제어하는 마이크로컴퓨터로써, 이 제어수단(104)은 상기 홀센서(27)에 의해 감지된 세탁모터(11)의 회전수에 비례하는 펄스신호를 입력받아 모터회전수가 일정RPM(약, 130)에 도달하는지를 감지하여 세탁물의 무게와 종류에 맞게 세탁수량을 최적제어한다.The control means 104 not only initializes the washing machine by receiving the DC voltage output from the power supply means 100, but also controls the overall operation of the washing machine according to the driving command signal input by the driving operation means 102. As a microcomputer, the control means 104 receives a pulse signal proportional to the rotational speed of the washing motor 11 sensed by the hall sensor 27 and the motor rotational speed reaches a predetermined RPM (about, 130). The amount of washing is optimally controlled according to the weight and type of laundry.

그리고, 급수구동수단(106)은 상기 제어수단(104)의 제어에 따라 온수 및 냉수의 세탁수를 세탁조(5)내에 급수하도록 급수수단(17)을 구동제어하고, 세탁모터구동수단(108)은 상기 제어수단(104)으로부터 출력되는 제어신호를 받아서 세탁물을 세탁 및 탈수하도록 세탁모터(11)를 정역회전제어한다.Then, the water supply driving means 106 drives and controls the water supply means 17 to supply the wash water of hot and cold water into the washing tank 5 under the control of the control means 104, and the washing motor driving means 108. Receiving the control signal output from the control means 104 controls the washing motor 11 forward and reverse rotation to wash and dehydrate the laundry.

회전수감지수단(110)은 상기 세탁모터구동수단(108)에 의해 구동되는 세탁모터(11)의 회전수를 감지하도록 홀센서(27)가 마그네트(25)와 교차함에 따라 변화하는 상기 마그네트(25)의 자속을 감지하여 세탁모터(11)의 회전수에 비례하는 펄스를 발생하여 상기 제어수단(104)에 출력하고, 배수밸브구동수단(112)은 상기 제어수단(104)으로부터 출력되는 제어신호를 받아서 상기 세탁조(5)내의 세탁수를 배수호스(23)를 통해 외부로 배출하도록 배수밸브(21)를 구동제어하며, 표시수단(114)은 상기 운전조작수단(102)에 의해 입력되는 세탁조건과 운전상태를 표시함은 물론, 상기 세탁기의 이상발생시에 에러를 표시한다.The rotation speed detecting unit 110 may change the magnets that change as the Hall sensor 27 intersects the magnet 25 so as to sense the rotation speed of the washing motor 11 driven by the washing motor driving unit 108. By detecting the magnetic flux of the 25 and generates a pulse proportional to the rotational speed of the washing motor 11 to output to the control means 104, the drain valve driving means 112 is a control output from the control means 104 Receiving a signal to drive the drain valve 21 to discharge the washing water in the washing tank 5 to the outside through the drain hose 23, the display means 114 is input by the operation operation means 102 In addition to displaying washing conditions and operating conditions, an error is displayed when an abnormality occurs in the washing machine.

이하, 상기와 같이 구성된 세탁기의 수위제어방법의 작용효과를 설명한다.Hereinafter, the effect of the water level control method of the washing machine configured as described above will be described.

도 4는 본 발명에 의한 세탁기의 수위제어 동작순서를 도시한 플로우챠트로서, 도 4에서 S는 스텝(STEP)을 표시한다.4 is a flowchart showing the operation of the water level control operation of the washing machine according to the present invention, in which S denotes a step.

먼저, 세탁기에 전원이 인가되면, 전원수단(100)에서는 도시되지 않은 교류전원단으로부터 공급되는 상용교류전원의 전원전압을 상기 세탁기의 구동에 필요한 소정의 직류전압으로 변환하여 각 구동회로 및 제어수단(104)에 출력한다.First, when power is applied to the washing machine, the power supply means 100 converts the power supply voltage of the commercial AC power supplied from an AC power terminal (not shown) into a predetermined DC voltage required for driving the washing machine, thereby driving each circuit and control means ( Output to 104).

따라서, 상기 제어수단(104)에서는 전원수단(100)으로부터 출력되는 직류전압을 입력받아 세탁기를 초기화시킨다.Therefore, the control means 104 receives the DC voltage output from the power supply means 100 and initializes the washing machine.

이때, 스텝S1에서는 사용자가 탈수조(7)내에 세탁물(부하)을 투입하고, 운전조작수단(102)에 의해 원하는 세탁조건(세탁종류, 세탁시간, 급수선택 등)을 입력한다음 운전버튼을 온시키면, 스텝S2에서 제어수단(104)은 탈수조(7)내에 투입된 세탁물을 세탁하는데 필요한 세탁수를 세탁조(5)내에 급수하도록 급수구동수단(106)에 제어신호를 출력한다.At this time, in step S1, the user inputs the laundry (load) in the dehydration tank 7, inputs the desired washing conditions (type of washing, washing time, water supply selection, etc.) by the operation operation means 102, and then presses the operation button. When turned on, the control means 104 outputs a control signal to the water supply driving means 106 to supply the washing water 5 to the washing tank 5 for washing the laundry put into the dewatering tank 7 in step S2.

이에 따라, 상기 급수구동수단(106)에서는 제어수단(104)으로부터 출력되는 제어신호를 입력받아 급수수단(17)을 동작시킴으로서 온수 또는 냉수의 세탁수가 세제용해기(19)를 거쳐 용해된 세제와 함께 세탁조(5)내에 급수된다.Accordingly, the water supply driving means 106 receives the control signal output from the control means 104 to operate the water supply means 17, and the washing water of hot or cold water passes through the detergent dissolver 19 and The water is supplied into the washing tank 5 together.

상기 세탁조(5)내에 세탁수가 급수되면, 스텝S3에서 제어수단(104)은 급수수단(17)의 동작에 따른 급수시간을 내장된 카운터에 의해 카운터하여 일정시간(세탁물의 양과 종류에 맞게 세탁수가 급수되는데 필요한 시간)이 경과하였는지를 판별하여, 일정시간이 경과하지 않은 경우(NO일 경우)에는 상기 스텝S2로 복귀하여 일정시간동안 계속해서 급수하면서 스텝S2이하의 동작을 반복수행한다.When the wash water is supplied to the washing tank 5, in step S3, the control means 104 counters the water supply time according to the operation of the water supply means 17 by a built-in counter to wash the water according to the amount and type of washing water. If a predetermined time has not elapsed (NO), the flow returns to the step S2, and the operation of the step S2 or less is repeated while the water is continuously supplied for a predetermined time.

상기 스텝S3에서의 판별결과, 일정시간이 경과한 경우(YES일 경우)에는 스텝S4로 나아가서 제어수단(104)은 세탁모터(11)를 회전시키도록 세탁모터구동수단(108)에 제어신호를 출력한다.As a result of the determination in step S3, when a predetermined time has elapsed (YES), the control means 104 sends a control signal to the washing motor driving means 108 to rotate the washing motor 11. Output

Detected by the rotational speed detection means 110 generates a pulse proportional to the rotational speed of the washing motor (11).

이에 따라, 스텝S6에서는 상기 회전수감지수단(110)에 의해 감지된 세탁모터(11)의 회전수가 제어수단(104)에 미리 설정되어 있는 일정RPM(세탁물의 양과 종류에 맞게 세탁수가 급수된 상태의 모터회전수, 약 130)에 도달하였는지를 판별하여, 세탁모터(11)의 회전수가 일정RPM에 도달하지 않은 경우(NO일 경우)에는 상기 스텝S2로 복귀하여 일정시간동안 계속해서 급수하면서 스텝S2이하의 동작을 반복수행한다.Accordingly, in step S6, the rotation speed of the washing motor 11 detected by the rotation speed detecting means 110 is set in the control means 104 in a predetermined RPM (the amount of washing water supplied according to the amount and type of the laundry). If the rotational speed of the washing motor 11 does not reach a constant RPM (NO), the flow returns to the step S2 and continues to supply water for a predetermined time. The following operation is repeated.

상기 스텝S6에서의 판별결과, 세탁모터(11)의 회전수가 일정RPM에 도달한 경우(YES일 경우)에는 스텝S7로 나아가서 제어수단(104)은 세탁조(5)내에 급수를 중지하도록 급수구동수단(106)에 제어신호를 출력한다.As a result of the discrimination in step S6, when the rotation speed of the washing motor 11 reaches a certain RPM (YES), the flow advances to step S7, whereby the control means 104 stops the water supply in the washing tank 5. A control signal is output to 106.

따라서, 상기 급수구동수단(106)에서는 제어수단(104)으로부터 출력되는 제어신호를 입력받아 급수수단(17)을 정지시킴으로서 세탁조(5)내에 급수가 중지된다.Therefore, the water supply driving means 106 receives the control signal output from the control means 104 and stops the water supply means 17 to stop the water supply in the washing tank 5.

상기 세탁조(5)내에 급수된 세탁수가 세탁물의 양과 종류에 맞는 최적의 세탁수위만큼 급수완료되면, 스텝S8에서는 세탁모터(11)의 구동에 의한 회전력이 벨트(13)를 통해 동력전달장치(15)에 전달되고, 상기 동력전달장치(15)에 전달된 세탁모터(11)의 회전력에 의해 펄세이터(9)가 좌우반전되면서 급수된 세탁수에 수류를 형성시킨다.When the wash water supplied to the washing tank 5 is water supplied by an optimal washing level suitable for the amount and type of laundry, in step S8, the rotational force driven by the washing motor 11 is transmitted through the belt 13 to the power transmission device 15. The pulsator 9 is reversed left and right by the rotational force of the washing motor 11 transmitted to the power transmission device 15 to form a stream of water in the wash water.

상기 펄세이터(9)의 좌우반전에 따라 형성되는 수류는 세탁수에 압력을 가하게 됨으로써 세탁물에 흡착된 때나 이물질 등을 분리시켜 세탁이 이루어진다.The water flow formed along the left and right inversion of the pulsator 9 is applied to the wash water to separate the adsorbed laundry or foreign matters to wash.

상기 세탁모터(11)의 구동에 따라 세탁이 이루어지면, 배수밸브(21)의 개방에 따라 세탁조(5)내의 오염된 물이 배수호스(23)를 통해 외부로 배출되고, 이어서 세탁모터(11)를 구동시켜 세탁물을 간헐적으로 탈수하는 간헐탈수공정을 수행한다.When washing is performed by driving the washing motor 11, contaminated water in the washing tank 5 is discharged to the outside through the drain hose 23 according to the opening of the drain valve 21, and then the washing motor 11. ) To perform an intermittent dehydration process to dehydrate the laundry intermittently.

이어서, 스텝S9에서는 헹굼행정을 수행하기위해 급수수단(17)을 통해 세탁수(헹굼수)가 세탁조(5)내에 급수되어 상기 세탁조(5)내에 급수된 세탁수가 세탁물의 양과 종류에 맞는 최적의 세탁수위만큼 급수완료되면, 세탁모터(11)의 구동에 따라 펄세이터(9)가 좌우반전되면서 세탁수에 수류를 형성시켜 헹굼을 수행한다.Subsequently, in step S9, the washing water (rinsing water) is supplied into the washing tank 5 through the water supply means 17 to perform a rinsing stroke, and the washing water supplied into the washing tank 5 is optimal for the amount and type of the laundry. When the water supply is completed as much as the washing water level, the pulsator 9 is inverted left and right according to the driving of the washing motor 11 to form a stream of water in the washing water to rinse.

헹굼을 수회 수행하면, 배수밸브(21)의 개방에 따라 세탁조(5)내의 헹굼수가 배수호스(23)를 통해 외부로 배출되고, 스텝S10에서는 세탁모터(11)의 구동에 따라 탈수조(7)가 한쪽방향으로 고속회전하면서 발생된 원심력에 의해 세탁물의 탈수가 이루어져 전체세탁행정을 완료한다.When the rinsing is performed several times, the rinsing water in the washing tank 5 is discharged to the outside through the drain hose 23 according to the opening of the drain valve 21, and in step S10 the dehydrating tank 7 is driven by the washing motor 11. ), The laundry is dewatered by the centrifugal force generated while rotating at a high speed in one direction to complete the whole washing process.
