Description

세탁기의 세탁방법{Method of washing in an electric washing machine}Method of washing in an electric washing machine}

본 발명은 세탁기의 세탁방법에 관한 것으로서, 특히 세제를 충분히 용해한 뒤 세탁행정을 실시하기에 적당하도록 한 세탁기의 세탁 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing method of a washing machine, and more particularly, to a washing method of a washing machine which is suitable for carrying out a washing administration after sufficiently dissolving a detergent.

종래의 세탁기는 세탁기에 세탁물을 넣은 상태에서 급수를 시작한다. 그런 후, 통이 약 20 rpm 정도의 낮은 회전수로 회전하면서 급수되는 물이 세탁물에 골고루 스며들게 한다. 이와 동시에 세탁기의 마이크로 프로세서(미도시)는 세탁조 (1)에 구비된 센서를 이용하여 세탁조(1)의 수위를 감지한다. 이때, 감지 결과 세탁조(1)의 수위가 세탁을 진행하기에 적절한 설정된 수위가 되면, 마이크로 프로세서는 미리 제조자마다 자체적으로 프로그램된 세탁절차에 따라 세탁 행정을 실행한다.The conventional washing machine starts to supply water in a state in which laundry is put in the washing machine. Then, the barrel rotates at a low speed of about 20 rpm, allowing the water to be evenly soaked in the laundry. At the same time, the microprocessor (not shown) of the washing machine senses the water level of the washing tank 1 by using a sensor provided in the washing tank 1. At this time, if the detected water level of the washing tank 1 is a suitable level for proceeding the washing, the microprocessor executes the washing process according to the washing procedure programmed by each manufacturer in advance.

그러나, 이와 같은 종래의 세탁기에서의 급수 절차는 단순히 급수와 세탁물에 물을 제공하여 세탁물이 젖도록 하는 역할만 제공한다. 따라서, 세탁 행정 중에 첨가되는 세제가 완전히 용해되지 않아서 세탁 효과가 초기에 미약하였다.However, such a water supply procedure in a conventional washing machine merely serves to supply water to the water supply and the laundry so that the laundry is wet. Therefore, the detergent added during the washing process did not completely dissolve, so the washing effect was initially weak.

본 발명의 목적은 이와 같은 종래 기술의 문제점을 감안하여 창출된 것으로서, 통이 도는 세탁기에서 초기의 낮은 수위에서 세제를 첨가하고 세탁조를 고속으로 회전시켜 세탁수를 순환시킴으로써, 세제 용해시간을 단축시켜 세탁력을 향상시킬 수 있는 세탁기의 세탁 방법을 제공하기 위한 것이다.An object of the present invention was created in view of the problems of the prior art, by adding detergent at an initial low water level in a tubular washing machine and rotating the washing tank at high speed to circulate the washing water, thereby reducing the detergent dissolution time. It is to provide a washing method of a washing machine that can improve the washing power.

이와 같은 목적을 달성하기 위하여 본 발명에 따른 세탁기의 세탁방법은,세탁조에 물과 세제를 함께 유입시키는 제 1 단계와; 상기 제 1 단계에서 유입되는 수위를 미리 설정된 1차 수위와 비교하는 제 2 단계와; 상기 제 2 단계에서 세탁조의 수위가 미리 설정된 1차 수위에 도달되면, 세탁조 내의 물과 세제가 원심력에 의하여 상기 세탁조에 형성되어 있는 탈수공 및 상기 세탁조와 외조 사이의 유로 가이드를 통과한 후 세탁조의 상부에서 세탁조로 낙하될 수 있을 정도의 속도로 세탁조와 펄세이터를 가속하여 일정속도로 회전시키는 제 3 단계와; 상기 제 3 단계에서 상기 세탁조와 펄세이터의 운전 시간이 기설정된 시간과 일치할 경우 모터를 정지시키는 제 4 단계와; 상기 제 4 단계에서 상기 세탁조와 펄세이터의 수위가 기설정된 2차 수위에 도달하면 급수를 중단하고 세탁행정을 진행하는 제 5 단계를 포함하는 것에 그 특징이 있다.Washing method of the washing machine according to the present invention to achieve the above object, the first step of introducing water and detergent together in the washing tank; A second step of comparing the water level flowing in the first step with a preset primary level; When the water level of the washing tank reaches the preset first level in the second step, the water and the detergent in the washing tank pass through the dehydration hole formed in the washing tank by the centrifugal force and the flow path guide between the washing tank and the outer tank, A third step of accelerating the washing tank and the pulsator at a speed such that the washing tank and the pulsator are rotated at a predetermined speed at an upper portion thereof; A fourth step of stopping the motor when an operation time of the washing tank and the pulsator coincides with a preset time in the third step; And a fifth step in which the water supply is stopped and the washing process is performed when the water level of the washing tank and the pulsator reaches the predetermined second water level in the fourth step.

여기서, 바람0직하게는 마이크로 프로세서에서 미리 설정 속도로 상기 세탁조를 회전시키는 경우, 상기 설정된 속도를 계속 유지하여 상기 세제와 물을 연속적으로 순환시킴으로써, 세제의 용해를 촉진시킨다.Here, when the washing tank is rotated at a preset speed in the microprocessor, the dissolution of the detergent is promoted by continuously circulating the detergent and water while maintaining the set speed.

이하, 첨부된 도면을 참조하면서 본 발명의 바람직한 실시 예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 세탁기의 세탁방법이 채용되는 세탁기는 도 2에 도시된 바와 같이 세탁조(lnner-tub)(1)와 외조(out-tub)(2)와, 유로 가이드(6)로 구성된다. 이와 같은 구성의 세탁기에서는 세탁조(1)의 회전시 원심력에 의해 물이 세탁조(1)에서 세탁조의 측면에 형성된 다수의 탈수공(미도시)을 통해 세탁조(1)와 외조(2) 사이의 공간으로 이동하고, 회전속도가 일정 rpm을 넘으면 세탁조(1)와 외조(2) 사이의 수위가 높아져서 유로 가이드(6)를 통해 다시 세탁조(1)로 유입된다.The washing machine employing the washing method of the washing machine according to the present invention is composed of a washing tank (lnner-tub) 1, an out-tub (2), and a flow path guide (6). In the washing machine having such a configuration, water is spaced between the washing tank 1 and the outer tank 2 through a plurality of dehydration holes (not shown) formed at the side of the washing tank in the washing tank 1 by centrifugal force when the washing tank 1 rotates. When the rotational speed exceeds a predetermined rpm, the water level between the washing tank 1 and the outer tank 2 is increased and flows back into the washing tank 1 through the flow path guide 6.

도 3은 본 발명에 따른 세탁기의 세탁방법이 채용된 세탁기에서의 순환 유량과 회전수의 관계를 나타낸 그래프이다.3 is a graph showing the relationship between the circulation flow rate and the rotation speed in the washing machine employing the washing method of the washing machine according to the present invention.

도 3에 도시된 바와 같이, 본 발명에서는 물의 재 순환시 세제가 물과 함께 재순환되며 세제가 용해되도록 하였다.As shown in FIG. 3, in the present invention, the detergent is recycled with water and the detergent is dissolved when water is recycled.

도 4는 본 발명과 종래의 기술에 따른 세제 용해 활성화 및 급수 전도도를 각각 나타낸 그래프이다.4 is a graph showing detergent dissolution activation and water supply conductivity according to the present invention and the prior art, respectively.

도 4에 도시된 바와 같이, 본 발명의 경우가 종래의 경우보다 세제 용해 활성화 및 급수 전도도가 월등히 우수함을 알 수 있다.As shown in Figure 4, it can be seen that the detergent dissolution activation and feedwater conductivity is much superior to the case of the present invention than the conventional case.

도 5는 본 발명에 따른 세탁기의 세탁방법의 실행과정을 설명하기 위한 흐름도이다.5 is a flowchart illustrating an execution process of a washing method of a washing machine according to the present invention.

도 5를 참조하면, 먼저, 사용자가 세탁조(1)내에 세탁물을 넣고 전원을 인가하면, 물이 세제 통(미도시)을 통과하며 세제와 함께 세탁조로 유입된다(S501).Referring to FIG. 5, first, when a user puts laundry into the washing tank 1 and applies power, water passes through a detergent container (not shown) and flows into the washing tank together with the detergent (S501).

이때, 세탁기의 마이크로프로세서는 세탁조(1)에 부착된 수위 감지 센서를 이용하여 세탁조(1)의 수위를 연속적으로 측정하여 감지한다(S502~S504).At this time, the microprocessor of the washing machine continuously measures and detects the water level of the washing tank 1 by using the water level sensor attached to the washing tank 1 (S502 to S504).

세탁기의 마이크로프로세서는 미리 설정된 수위가 감지되면, 세탁조(1)의 회전수를 증가시켜 설정된 속도(rpm)로 세탁조(1)를 회전시킨다(S505). 이때의 속도는 도 3에 의해서 물이 재순환 되는 속도로 진행된다. 또한, 마이크로 프로세서는 세탁조(1)의 속도를 판단하여 더 이상 속도를 증가시키지 않도록 제어하여 설정된 속도를 계속 유지하며 세제와 물이 연속적으로 순환하게 하여 세제가 용해되도록 한다(S506,S507).When the preset water level is detected, the microprocessor of the washing machine increases the rotation speed of the washing tub 1 to rotate the washing tub 1 at a set speed rpm (S505). The speed at this time proceeds to the rate at which the water is recycled by FIG. In addition, the microprocessor determines the speed of the washing tank 1 so as not to increase the speed anymore to maintain the set speed and to continuously circulate the detergent and water so that the detergent is dissolved (S506, S507).

이어, 세탁기의 마이크로 프로세서는 현재 시간을 판단하여, 일정시간이 지나면 모터의 회전을 정지시켜 세탁조(1)의 회전을 중지시킨다(S508, S509). 이때, 마이크로 프로세서는 세탁조(1)의 수위를 판단하여, 판단 결과 세탁조(1)의 수위가 설정된 세탁 수위에 이른 것으로 판단되면, 급수를 중지하고 미리 설정된 세탁 행정을 진행한다(S510~S513).Subsequently, the microprocessor of the washing machine determines the current time and stops the rotation of the motor 1 after a predetermined time passes (S508 and S509). At this time, the microprocessor determines the water level of the washing tank 1, and if it is determined that the water level of the washing tank 1 has reached the set washing level, the water supply stops and proceeds with the preset washing stroke (S510 to S513).

이상과 같은 본 발명에 따르면, 세제를 급수시간에 공급하여 용해시킬 수 있기 때문에 세탁효과가 빠르게 나타나며, 또한 세탁시간을 종래 보다 단축시킬 수 있다. 따라서, 본 발명에 따른 세탁방법이 적용된 세탁기의 전체적인 제품 성능을 크게 향상시킬 수 있다.According to the present invention as described above, since the detergent can be supplied and dissolved in the water supply time, the washing effect appears quickly, and the washing time can be shorter than before. Therefore, the overall product performance of the washing machine to which the washing method according to the present invention is applied can be greatly improved.
