상기 드럼(11)은 그 전표면에 세탁물이 상기 드럼(11)내에서 뒹굴 수 있게 함과 동시에 상기 터브(9)내의 세탁수가 드럼(11)내로 유동되도록 다수개의 관통구멍(11a)이 형성되어 있고, 상기 드럼(11)의 내부에는 서로 120°씩 일정한 간격으로 떨어져 세탁물을 끌어 올리면서 낙하시켜 빨래방망이 기능을 하는 수류조절부재(11b)가 결착되어 있다.The drum 11 has a plurality of through-holes 11a formed on the front surface thereof so that laundry can be rolled in the drum 11 and the wash water in the tub 9 flows into the drum 11. The inside of the drum 11 has a water flow regulating member 11b attached to the laundry net by dropping each other at regular intervals 120 ° apart and dropping while washing the laundry.

상기와 같이 구성된 종래의 드럼세탁기에 있어서, 먼저 사용자가 드럼(11)내에 세탁물(의류)을 투입한다음, 조작부(5)를 조작하여 원하는 세탁조건(세탁종류,삶는 온도, 세탁코스, 건조시간 등)을 입력하고 동작버튼을 온시키면, 도시되지 않은 수도전으로부터 공급되는 세탁수가 온 ·냉급수밸브(7,8)를 통해 터브(9)내에 급수된다.In the conventional drum washing machine configured as described above, the user first puts laundry (clothing) into the drum 11, and then manipulates the operation unit 5 to perform desired washing conditions (type of washing, boiling temperature, washing course, drying time). And the like, and the operation button is turned on, the washing water supplied from the water tap not shown is supplied to the tub 9 through the hot / cold water valves 7 and 8.

상기 터브(9)내에 세탁수가 급수되면, 모터(27)의 구동에 따라 드럼(11)이 좌우반전되면서 고속으로 회전하여 급수된 세탁수에 수류가 형성됨과 동시에 세탁물에 물리적인 힘이 가해져 세탁물에 흡착된 때나 이물질 등을 분리시켜 세탁, 헹굼, 탈수 및 건조과정을 거친다.When the wash water is supplied to the tub 9, the drum 11 rotates at high speed while the motor 27 is driven to rotate at a high speed, so that water flow is formed in the washed water and at the same time, a physical force is applied to the laundry.

이하, 본 발명의 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 의한 드럼세탁기는 도 1에 도시한 종래의 구성과 동일하므로 동일명칭 및 동일부호를 명기하여 중복되는 설명을 생략한다.Drum washing machine according to the present invention is the same as the conventional configuration shown in Fig. 1, the same name and the same reference numerals are specified by the overlapping description is omitted.

도 2에 도시한 바와같이, 전원수단(100)은 도시되지 않은 교류전원단으로부터 공급되는 상용교류전압을 상기 드럼세탁기의 동작에 필요한 소정의 직류전압으로 변환하여 각 구동회로에 출력하고, 운전조작수단(102)은 사용자가 원하는 세탁조건(세탁종류, 삶는 온도, 세탁코스, 건조시간 등)을 입력하도록 다수의 기능버튼을 구비한 조작부(5) 등으로 구성된다.As shown in Fig. 2, 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 drum washing machine, and outputs it to the respective driving circuits. 102 is composed of an operation unit 5 and the like provided with a plurality of function buttons to input the washing conditions (type of washing, boiling temperature, washing course, drying time, etc.) desired by the user.

제어수단(104)은 상기 전원수단(100)으로부터 출력되는 직류전압을 인가받아드럼세탁기를 초기화시킴은 물론, 상기 운전조작수단(102)에 의해 입력된 운전명령신호에 따라 상기 드럼세탁기의 전체적인 동작을 제어하는 마이크로컴퓨터로써, 이제어수단(104)은 정상탈수 진행전에 거품의 양에 따라 변화하는 수위데이터를 기설정된 기준수위데이터와 비교하여 거품의 과다발생여부를 판단하고, 거품의 과다발생시에는 정상탈수행정을 바로 수행하지 않고 헹굼행정을 추가로 수행한다.The control means 104 not only initializes the drum washing machine by receiving the DC voltage output from the power supply means 100 but also operates the drum washing machine according to the operation command signal input by the driving operation means 102. As a microcomputer to control the control unit 104, the water control unit 104 compares the water level data, which is changed according to the amount of bubbles before the normal dehydration, with the predetermined reference water level data, and determines whether the bubbles are excessive. An additional rinse stroke is performed without performing a normal dehydration stroke.

그리고, 급수밸브구동수단(106)은 상기 제어수단(104)의 제어에 따라 도시되지 않은 수도전으로부터 공급되는 온수 및 냉수를 터브(9)내에 급수하도록 온 ·냉급수밸브(7,8)를 구동제어하고, 수위감지수단(108)은 상기 터브(9)내에 세탁수가급수됨에 따라 또는 헹굼행정의 간헐탈수 후 거품의 양에 따라 압력이 변화하면 수위센서 내부에 있는 주파수 발진회로의 주파수가 비례 또는 반비례적으로 변환되는원리에 따라 수위를 감지하는 일반적인 방식이다.The water supply valve driving means 106 supplies the hot / cold water supply valves 7 and 8 to supply the hot water and the cold water supplied from the tap water not shown in the tub 9 under the control of the control means 104. The driving control and the water level detecting means 108 are proportional to the frequency of the frequency oscillation circuit inside the water level sensor when the pressure changes as the washing water is supplied into the tub 9 or according to the amount of foam after intermittent dehydration of the rinsing stroke. Or it is a general way of detecting the water level according to the inversely transformed principle.

또한, 모터구동수단(110)은 상기 제어수단(104)으로부터 출력되는 제어신호를 받아서 세탁물을 세탁 및 탈수하도록 모터(27)를 정역회전제어하고, 배수펌프구동수단(112)은 상기 제어수단(104)으로부터 출력되는 제어신호를 받아서 상기터브(9)내의 세탁수를 외부로 배출하도록 배수펌프(29)를 구동제어한다.In addition, the motor driving means 110 receives the control signal output from the control means 104 and the forward and reverse rotation control of the motor 27 to wash and dehydrate the laundry, the drain pump driving means 112 is the control means ( Receiving the control signal output from the 104 to drive the drain pump 29 to discharge the wash water in the tub (9) to the outside.

또, 표시수단(114)은 상기 운전조작수단(102)에 의해 입력되는 세탁조건과 운전상태를 표시함은 물론, 상기 드럼세탁기의 이상발생시에 에러(거품 과다발생)를 표시한다.In addition, the display means 114 not only displays the washing condition and the operation state input by the driving operation means 102, but also displays an error (excessive foaming) when an abnormality occurs in the drum washing machine.

이하, 상기와 같이 구성된 드럼세탁기의 거품제거방법의 작용효과를 설명한다.Hereinafter, the operation and effect of the bubble removing method of the drum washing machine configured as described above will be described.

도 3a 및 도 3b는 본 발명의 일실시예에 의한 드럼세탁기의 거품제거 제어동작순서를 도시한 플로우챠트로서, 도 3a 및 도 3b에서 S는 스텝(STEP)을 표시한다.3A and 3B are flowcharts illustrating a bubble removing control operation procedure of the drum washing machine according to an embodiment of the present invention, in which S denotes a step (STEP) in FIGS. 3A and 3B.

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

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

이때, 스텝S1에서는 사용자가 드럼(11)내에 세탁물(부하)을 투입하고, 운전조작수단(102)에 의해 원하는 세탁조건(세탁종류, 삶는 온도, 세탁코스, 건조시간등)을 입력한다음 동작버튼을 온시키면, 스텝S2에서 제어수단(104)은 드럼(11)내에투입된 세탁물의 양을 감지하는데 필요한 세탁수를 터브(9)내에 급수하도록 급수밸브구동수단(106)에 제어신호를 출력한다.At this time, in step S1, the user inputs the laundry (load) into the drum 11 and inputs the desired washing conditions (type of washing, washing temperature, washing course, drying time, etc.) by the driving operation unit 102. When the button is turned on, in step S2, the control means 104 outputs a control signal to the water supply valve driving means 106 so as to feed the washing water necessary for sensing the amount of laundry introduced into the drum 11 into the tub 9. .

이에 따라, 상기 급수밸브구동수단(106)에서는 제어수단(104)으로부터 출력되는 제어신호를 입력받아 온 ·냉급수밸브(7,8)를 개방(온)시킴으로서 수도전으로부터 공급되는 온수 또는 냉수의 세탁수가 터브(9)내에 급수된다.Accordingly, the water supply valve driving means 106 receives the control signal output from the control means 104 to open (on) the on / cold water valves 7 and 8 to supply hot or cold water supplied from the tap water. Washing water is supplied to the tub (9).

이때, 스텝S3에서는 상기 온 ·냉급수밸브(7,8)의 개방에 따른 급수동작에 의해 상승되는 수위를 수위감지수단(108)에서 감지하여 제어수단(104)에 출력하는데, 이는 세탁수가 공급됨에 따라 압력이 상승하면 수위센서 내부에 있는 주파수 발진회로의 주파수가 낮아지는 원리에 따라 변화하는 주파수를 제어수단(104)에서 입력받아 세탁수의 수위를 감지한다.At this time, in step S3, the water level sensing unit 108 detects the water level rising by the water supply operation according to the opening of the hot / cold water supply valves 7 and 8, and outputs it to the control unit 104. As the pressure rises, the frequency of the frequency oscillation circuit inside the water level sensor is reduced according to the principle that the control unit 104 receives the changing frequency and detects the water level of the wash water.

이어서, 스텝S4에서는 상기 수위감지수단(108)에 의해 감지된 수위가 제어수단(104)에 미리 설정되어 었는 설정수위(세탁물의 양을 감지하는데 필요한 세탁수위)까지 급수되었는지를 판별하여, 설정수위까지 급수되지 않은 경우(N0일 경우)에는 상기 스텝S2로 복귀하여 설정수위에 도달할 때까지 온 ·냉급수밸브(7,8)를 개방하여 급수를 계속하면서 스텝S2이하의 동작을 반복수행한다.Subsequently, in step S4, it is determined whether the water level detected by the water level detecting means 108 is supplied to the setting level (washing water level required to detect the amount of laundry) that has been set in advance in the control means 104, and thus the setting water level. If the water is not supplied until (N0), the flow returns to the step S2 and the hot and cold water supply valves 7 and 8 are opened until the set water level is reached. .

상기 스텝S4에서의 판별결과, 설정수위까지 급수된 경우(YES일 경우)에는 스텝S5로 나아가서 제어수단(104)은 급수밸브구동수단(106)을 제어하여 온·냉급수밸브(7,8)를 폐쇄(오프)시키고, 모터(27)를 구동시키도록 모터구동수단(110)에 제어신호를 출력한다.As a result of the discrimination in step S4, when water is supplied up to the set water level (YES), the flow advances to step S5, and the control means 104 controls the water supply valve driving means 106 to control the hot / cold water supply valves 7 and 8.

Drain to the outside.

이어서, 스텝S11에서 제어수단(104)은 모터(27)를 간헐적으로 구동시켜 세탁물을 간헐적으로 탈수하는 간헐탈수공정을 1∼3회 수행하고, 정상탈수행정을 진행하기 전에 스텝S12로 나아가서 간헐탈수 후의 수위를 수위감지수단(108)에서 감지하여 제어수단(104)에 출력하는데, 이는 거품의 양에 따라 압력이 변화하면 수위센서 내부에 있는 주파수 발진회로의 주파수가 낮아지는 원리에 따라 변화하는 주파수를 제어수단(104)에서 입력받아 수위데이터(H)를 감지한다.Subsequently, in step S11, the control means 104 performs the intermittent dehydration process of intermittently dehydrating the laundry by driving the motor 27 intermittently 1 to 3 times, and proceeds to step S12 before proceeding to the normal dehydration stroke. The later water level is sensed by the water level detecting means 108 and output to the control means 104, which changes in accordance with the principle that the frequency of the frequency oscillation circuit inside the water level sensor decreases when the pressure changes according to the amount of bubbles.

(Hs) or more (YES), it is determined that the foam is excessive, and the flow proceeds to step S14, whereby the control means 104 supplies the water supply valve driving means to supply the wash water in the tub 9 to further perform a rinsing stroke. A control signal is output to 106.

따라서, 상기 급수밸브구동수단(106)에서는 제어수단(104)으로부터 출력되는 제어신호를 입력받아 온 ·냉급수밸브(7,8)를 개방(온)시킴으로서 수도전으로부터 공급되는 온수 또는 냉수의 세탁수가 터브(9)내에 급수된다.Therefore, the water supply valve driving means 106 receives the control signal output from the control means 104 to open (on) the on / cold water valves 7 and 8 to wash the hot or cold water supplied from the tap water. Water is supplied to the tub 9.

상기 터브(9)내에 세탁수가 급수완료되면, 스텝S15로 나아가서 제어수단(104)은 온 ·냉급수밸브(7,8)를 폐쇄(오프)시키고, 모터(27)를 구동시키도록 모터구동수단(110)에 제어신호를 출력한다.When the wash water is completed in the tub 9, the flow proceeds to step S15, and the control means 104 closes (off) the on / cold water supply valves 7 and 8 and drives the motor 27 to drive the motor 27.
