본 발명에 따른 세탁기의 급수제어방법은 급수와 헹굼 및 세탁을 함께 수행하는 경우에 급수시 초기설정수위에서 일정 수위를 뺀 수위이하까지만 급수와 함께 헹굼 및 세탁을 수행하고, 초기설정수위에서 일정수위를 뺀 수위이상까지 급수된 경우에는 급수만을 수행하도록 펄세이터의 구동을 정지시킨다.The water supply control method of the washing machine according to the present invention performs rinsing and washing with water supply only up to the water level minus a certain level from the initial setting water level when water supply, rinsing and washing are performed together, and the water level is constant at the initial setting water level. In case of water supply above the water level minus the pulsator, stop the operation of the pulsator to perform water supply only.
따라서, 본 발명에 따른 세탁기의 급수제어방법에 의하여 급수와 함께 세탁 및 헹굼을 수행하는 경우 급수종료여부판단시 펄세이터의 구동에 따른 세탁조내부의 물의 출렁임을 방지하여 정확한 수위감지가 가능하게 된다.Therefore, when washing and rinsing with water supply according to the water supply control method of the washing machine according to the present invention, it is possible to detect the water level in the washing tank by preventing the swelling of the water in the washing tank according to the driving of the pulsator when the water supply is terminated.
Description
본 발명은 세탁기의 급수제어방법에 관한 것으로, 더욱 상세하게는 급수와 세탁,급수와 헹굼을 함께 수행하도록 된 세탁기의 급수제어방법에 관한 것이다.The present invention relates to a water supply control method of a washing machine, and more particularly, to a water supply control method of a washing machine to perform water supply and washing, water supply and rinsing together.
일반적으로 세탁기는 도 1에 도시한 바와 같이, 본체(1)의 내측에 세탁수가 담겨지는 원통형상의 수조(2)가 배치되고, 그 내측으로는 세탁물이 담기는 세탁조(3)가 회동가능하게 장착된다. 세탁조(3)에는 다수의 통공(3a)이 형성되어 수조(2)와 연통되고, 그 하측에는 펄세이터(4)가 회전가능하게 장착된다. 또한, 수조(2) 바닥의 외측에는 세탁조(3)를 정역회전시키기 위한 모터(5)가 장착되고, 중앙에는 세탁시에 모터(5)의 회전력을 전달받아 펄세이터(4)를 시계방향 및 반시계방향으로 저속회전시키고 탈수시에는 모터(5)의 회전력을 전달받아 세탁조(3)를 고속으로 회전시키는 클러치기구(6)가 장착된다.In general, as shown in FIG. 1, a washing machine 2 in which a washing water is placed is disposed inside the main body 1, and a washing tank 3 in which laundry is contained is rotatably mounted in the washing machine. do. A plurality of through holes 3a are formed in the washing tank 3 so as to communicate with the water tank 2, and a pulsator 4 is rotatably mounted on the lower side thereof. In addition, a motor 5 for forward and reverse rotation of the washing tank 3 is mounted on the outside of the bottom of the water tank 2, and the center receives the rotational force of the motor 5 at the time of washing, and rotates the pulsator 4 clockwise and The clutch mechanism 6 which rotates the washing tank 3 at a high speed by receiving the rotational force of the motor 5 when rotating at a low speed counterclockwise and dewatering is mounted.
이러한 구성을 갖는 세탁기의 일반적인 세탁방법은 크게 세탁행정, 최고 5회의 헹굼행정 및 탈수행정으로 이루어진다. 이때 세탁행정 및 헹굼행정은 세탁조내에 급수하는 급수과정을 포함하는 데, 급수과정이 완료된 후에 세탁 및 헹굼을 수행하는 경우 전체 세탁시간을 줄이는 데 한계가 있어 근래에는 급수과정과 세탁 및 헹굼을 일정 시간동안 함께 수행하여 세탁시간을 단축시킬 수 있도록 한다.The general washing method of the washing machine having such a configuration consists of a washing stroke, a maximum of five rinsing strokes and a dehydrating stroke. In this case, the washing administration and the rinsing administration include a water supply process for supplying water into the washing tank, and when washing and rinsing are performed after the water supply process is completed, there is a limit in reducing the overall washing time. Work together to shorten the washing time.
그러나, 이러한 경우에 있어서 급수과 동시에 세탁 및 헹굼을 하게 되는 경우 급수중에 펄세이터의 정역회전과 함께 세탁조내부의 물이 출렁거려 정확한 수위감지가 불가능하며, 따라서 초기에 설정받은 세탁수위까지의 급수가 정확히 이루어지지 못하는 문제점이 있었다.However, in this case, when washing and rinsing at the same time as the water supply, the water inside the washing tank slumps with the reverse rotation of the pulsator during the water supply, so that accurate water level detection is impossible. There was a problem that could not be achieved.
따라서, 본 발명은 상기의 문제점을 해결하기 위하여 안출된 것으로써 그 목적은 급수와 헹굼 및 세탁을 함께 수행하는 경우에 있어서 정확한 수위감지에 따른 급수가 가능하도록 된 세탁기의 급수제어방법을 제공하고자 하는 것이다.Accordingly, the present invention has been made in order to solve the above problems and its object is to provide a water supply control method of a washing machine that is capable of supplying water according to accurate water level detection when performing water supply, rinsing and washing together. will be.

이러한 구성을 갖는 본 발명에 따른 세탁기의 헹굼제어방법을 이하에 상세히 설명한다.The rinsing control method of the washing machine according to the present invention having such a configuration will be described in detail below.
도 3은 본 발명에 따른 세탁기의 헹굼제어방법을 보인 플로우차트이다.3 is a flowchart illustrating a rinsing control method of a washing machine according to the present invention.
도 3에 도시한 플로우차트에서 보는 바와 같이, 본 발명에 따른 세탁기의 헹굼제어방법은 먼저, 단계(s10)에서는 전원이 인가된 상태에서 사용자로부터 각 세탁모드 및 세탁수위등을 설정받은 뒤 세탁조내부로 급수를 수행하게 된다. 또한 단계(s11)에서는 수위감지부(12)를 통해 세탁조(3) 내부의 수위를 감지한다. 이때 단계(s12)에서는 초기에 사용자로부터 설정받은 세탁수위 즉 초기설정수위가 중수위이상인가를 판단하게 되는 데, 일예로 사용자가 설정가능한 수위는 최저,저,중,고,최고수위인 것으로 가정한다.As shown in the flow chart shown in Figure 3, the rinsing control method of the washing machine according to the present invention, first, in step (s10) after receiving the washing mode and the washing water level, etc. from the user in the state that the power is applied inside the washing tank Watering is performed. In addition, in step (s11) it detects the water level inside the washing tank 3 through the water level detection unit (12). At this time, it is determined in step (s12) whether the washing level set by the user, that is, the initial setting level is higher than the medium level. For example, it is assumed that the user settable level is the lowest, low, medium, high, or high level. do.
단계(s12)에서의 판단결과 사용자가 초기설정한 수위가 중수위이상인 고수위인 경우에는 단계(s13)으로 진행하여 수위감지부(12)에서 감지된 세탁조내부의 수위가 초기설정수위로부터 일정 수위값(20mm)을 뺀값 즉, 초기세탁정지수위인가를 판단한다. 상기 단계(s13)의 판단결과 세탁조내부의 수위가 초기설정수위보다 20mm낮은 초기세탁정지수위이하이면 단계(s15)로 진행하여 급수와 동시에 펄세이터(4)를 정역구동시켜 세탁조내부의 세탁물을 세탁한다.As a result of the determination in step S12, when the water level set by the user is higher than the medium level, the flow proceeds to step S13, and the level inside the washing tank detected by the water level detection unit 12 is a predetermined level value from the initial level. (20mm) minus the initial washing stoppage level. If the water level inside the washing tank is lower than the initial washing stop water level 20mm lower than the initial setting water level as the result of the determination in step (s13), the process proceeds to step (s15), where the water in the washing tank is washed by driving the pulsator 4 forward and backward simultaneously with water supply. do.
반면, 세탁조내부의 급수가 진행되어 세탁조내부의 수위가 초기세탁정지수위보다 높은 경우에는 단계(s14)로 진행하여 펄세이터(4)의 구동을 정지시켜 본세탁이전에 급수와 함께 세탁을 수행하는 초기세탁을 정지시켜 세탁조내부의 물이 출렁거리는 것을 방지하여 정확한 수위감지가 가능하도록 한다.On the other hand, when the water supply in the washing tank is progressed and the water level in the washing tank is higher than the initial washing stop level, the flow proceeds to step S14 to stop the driving of the pulsator 4 to perform the washing together with the water supply before the main washing. By stopping the initial washing to prevent the water in the washing tank to drift to enable accurate water level detection.
이때 단계(s16)에서는 초기세탁이 중지됨에 따른 펄세이터(4)의 구동정지로 세탁조내부의 물이 출렁거리지 않고 잠잠해진 상태에서 수위감지부(12)를 통해 감지된 수위가 초기설정수위와 일치하는가를 판단하고, 세탁조내부의 수위가 초기설정수위와 일치하면 단계(s17)로 진행하여 세탁조내부로의 급수를 종료하게 된다.At this time, in the step (s16), the water level detected by the water level detection unit 12 in the state in which the water inside the washing tank is not slumped due to the driving stop of the pulsator 4 as the initial washing is stopped, and coincides with the initial set water level. If the water level inside the washing tank is equal to the initial set water level, the flow proceeds to step s17 to terminate the water supply to the inside of the washing tank.
이상에서 설명한 바와 같이, 본 발명에 따른 세탁기의 급수제어방법은 급수와 헹굼 및 세탁을 함께 수행하는 경우에 급수시 초기설정수위에서 일정 수위를 뺀 수위이하까지만 급수와 함께 헹굼 및 세탁을 수행하고, 초기설정수위에서 일정수위를 뺀 수위이상까지 급수된 경우에는 급수만을 수행하도록 펄세이터의 구동을 정지시킨다.As described above, the water supply control method of the washing machine according to the present invention performs rinsing and washing with water supply only when water supply and rinsing and washing are performed together with water supply up to the water level minus a certain level from the initial setting water level. In case of water supply above the preset water level minus a certain level, stop the operation of the pulsator to perform water supply only.
따라서, 본 발명에 따른 세탁기의 급수제어방법에 의하여 급수와 함께 세탁 및 헹굼을 수행하는 경우 급수종료여부판단시 펄세이터의 구동에 따른 세탁조내부의 물의 출렁임을 방지하여 정확한 수위감지가 가능하게 된다.Therefore, when washing and rinsing with water supply according to the water supply control method of the washing machine according to the present invention, it is possible to detect the water level in the washing tank by preventing the swelling of the water in the washing tank according to the driving of the pulsator when the water supply is terminated.
