본 발명은 세탁기에 관한 것으로서, 보다 상세하게는 온수를 사용하는 예비세정단계를 통해 세정성능을 향상시킬 수 있는, 교반식 세탁기의 세탁방법에 관한 것이다.The present invention relates to a washing machine, and more particularly, to a washing method of a stirring washing machine that can improve the cleaning performance through a pre-cleaning step using hot water.

일반적으로 세탁기는 주로 전동기를 통한 기계적인 작동에 의해 의류 등을 세탁하기 위한 것으로, 그 구조와 세탁방식에 따라 교반식(agitator type)과 드럼식(drum type) 및 와권식(pulsator type)으로 구분되며, 대략, 세탁에 직접 기여하는 세탁부와, 상기 세탁부의 작동을 위한 동력을 공급하는 구동부 및 외형을 형성하는 케이스 등으로 구성된다. In general, a washing machine is mainly for washing clothes by a mechanical operation through an electric motor. The washing machine is classified into agitator type, drum type, and pulsator type according to its structure and washing method. , Roughly, a washing unit directly contributing to washing, a driving unit for supplying power for the operation of the washing unit, and a case forming an outline.

여기서, 상기 교반식 세탁기의 세탁부는 도 1에 나타난 것과 같이 케이스(10)내에 설치된 저수조(12)와, 저수조(12)에 내장된 세탁조(14)와, 세탁조(14)내에 위치되며 구동모터(20)와 트랜스미션(22)에 의해 연결된 교반봉(16) 및 급, 배수밸브장치(30)(32) 등을 포함하여 이루어져 있는데, 상기 저수조(12)는 케이스(10) 내에서 서스펜션 기구(18)에 의해 지지되어 있으며, 세탁조(14)는 그 벽면에 다수개의 누수홀(14a)이 구비된 형태로서 상기 구동모터(20)에 의해 회전 가능한 구조로 장착되어 있다. Here, the washing unit of the stirring washing machine as shown in Figure 1, the reservoir 12 installed in the case 10, the washing tank 14 built in the reservoir 12, and the washing tank 14 is located in the drive motor ( 20) and the stirring rod 16 connected by the transmission 22 and the supply and drain valve device 30, 32, etc., the reservoir 12 is the suspension mechanism 18 in the case 10 It is supported by), the washing tank 14 is provided with a plurality of leak holes (14a) on its wall surface is mounted in a rotatable structure by the drive motor (20).

그리고, 급수밸브장치(30)는 도 2에 나타난 것과 같이 냉수배관(C)과 연결되는 냉수밸브(301) 및 온수배관(H)과 연결되는 온수밸브(302)로 이루어져 있으며, 상기 냉, 온수밸브(301)(302)의 개폐제어는 세정행정에 앞서 사용자가 설정한 로직에 의해 제어되는 방식으로 이루어진다. The water supply valve device 30 includes a cold water valve 301 connected to the cold water pipe C and a hot water valve 302 connected to the hot water pipe H, as shown in FIG. 2. Opening and closing control of the valves 301 and 302 is performed in a manner controlled by logic set by the user prior to the cleaning stroke.                         

상술한 바와 같이 구성된 교반식 세탁기의 세탁방법은 급수밸브장치(30)에 의해 세탁조(14) 내로 세탁수가 급수되는 급수행정과, 급수행정 종료 후 교반봉(16)의 회전 작동으로 세탁수와 빨랫감(W)을 일정 시간동안 교반시키는 세정행정과, 세정행정 종료 후 배수밸브(32)를 통해 세탁수를 배수한 다음, 재급수하여 일정 횟수만큼 빨랫감(W)을 헹구는 헹굼행정과, 헹굼행정 종료 후 세탁조(14)를 고속으로 회전시켜 빨랫감(W)을 탈수하는 탈수행정으로 이루어진다.The washing method of the stirring washing machine configured as described above is a water supply stroke in which the washing water is supplied into the washing tank 14 by the water supply valve device 30, and the washing water and the feeling of washing by rotating the stirring rod 16 after the water supply stroke is completed. A washing stroke that stirs W) for a predetermined time, a rinsing stroke that drains the wash water through the drain valve 32 after the completion of the washing stroke, and then rinsed the wash feeling W for a predetermined number of times, and after the rinsing stroke, the washing tank ( 14) rotates at a high speed to the dehydration stroke to dehydrate the clothes (W).

이와 같은 세탁방법 중, 급수행정에서는 각 급수밸브(301)(302)를 통해 유입되는 물이 세제통(31)을 거치면서 세제와 혼합된 세탁수가 공급되고, 세정행정에서는 세탁수에 함유된 세제의 화학작용과 함께 교반봉(16)에 의한 물리적인 작용으로 빨랫감(W)에 묻어 있는 오염물질이 제거되는 세정작용이 진행되는데, 이때 상기 교반봉(16)은 트랜스미션(22)에 의해 그 회전방향이 간헐적으로 반전되는 정역회전을 반복함으로써 세탁효과를 높이게 된다. In this washing method, in the water supply administration, the water flowing through the water supply valves 301 and 302 passes through the detergent container 31, and the washing water mixed with the detergent is supplied. In addition to the chemical action, the cleaning action is performed to remove contaminants from the clothes (W) by the physical action by the stirring rod 16. At this time, the stirring rod 16 is rotated by the transmission 22 in the direction of rotation thereof. By repeating this intermittent reverse rotation, the washing effect is enhanced.

이어서, 진행되는 헹굼행정에서는 세제가 혼합되지 않은 세탁수가 공급되어 빨랫감(W)에 묻어있는 세제성분이 제거되고, 탈수행정에서는 세탁조(14)가 일측방향으로 빠르게 회전함으로써 빨랫감(W)이 세탁조(14) 내벽에 밀착된 상태에서 원심력에 의해 빨랫감(W)의 물기가 누수홀(14a)을 통해 빠져나가게 된다. 상기 탈수행정에서는 세탁조(14)와 교반봉(16)이 동시에 같은 방향으로 회전함으로써 빨랫감(W)이 교반봉(16)에 걸려 훼손되는 것이 방지되며, 배수밸브장치(32)가 개방됨으로써 세탁조(14)의 누수홀(14a)을 통해 배출된 물기를 세탁기의 외부로 배수하게 된다. Subsequently, in the ongoing rinsing cycle, the washing water without mixing the detergent is supplied to remove the detergent component on the clothes (W), and in the dehydrating stroke, the washing tank (14) rotates quickly in one direction so that the washing (W) is the washing tank ( 14) The water of the laundry (W) is discharged through the leak hole (14a) by the centrifugal force in a state in close contact with the inner wall. In the dehydration stroke, the washing tank 14 and the stirring rod 16 are rotated in the same direction at the same time, thereby preventing the laundry feeling W from being caught by the stirring rod 16 and being damaged, and opening the drain valve device 32 to open the washing tank ( The water discharged through the leak hole 14a of 14 is drained to the outside of the washing machine.                         

그러나, 상술한 바와 같은 종래의 교반식 세탁기의 세탁방법에 의하면 세정행정에서 교반봉(16)의 작동 특성상, 좌우방향의 수류와 함께 상하방향의 수류가 조합된 양방향 수류가 형성되므로 드럼식이나 와권식 세탁기에 비해 세탁과정에서 빨랫감(W)이 엉키지는 않게 되나, 교반봉(16)과 빨랫감(W)이 마찰되기 때문에 빨랫감(W)의 손상이 심하고, 많은 양의 세탁수를 필요로 할 뿐만 아니라, 교반봉(16)의 작용만으로는 강한 수류를 형성할 수 없는 등 세탁력이 약하다는 문제점이 발생한다. However, according to the washing method of the conventional stirring washing machine as described above, due to the operating characteristics of the stirring rod 16 in the washing stroke, the two-way water flow combined with the water flow in the left and right directions is formed drum-type or spiral winding type Compared to the washing machine, the washing process (W) is not tangled in the washing process, but because the stirring rod (16) and the laundry (W) friction, the damage of the laundry (W) is severe and not only requires a large amount of washing water. There is a problem that the washing power is weak, such as a strong water flow can not be formed only by the action of the stirring rod 16.

따라서, 상기 일반 교반식 세탁기의 단점을 보완하기 위하여, 이른바 혼합교반식 세탁기가 개발되었는데. 이러한 혼합교반식 세탁기에 의하면, 교반봉(16)의 작동만으로 빨랫감(W)을 세탁하는 교반세정(agitator wash)단계와, 교반봉(16)과 세탁조(14)가 동시에 회전하여 빨랫감(W)을 세탁하는 여과세정(filtration wash)단계가 조합된 세정행정이 수행된다. Therefore, to compensate for the shortcomings of the general stirring washing machine, a so-called mixed stirring washing machine was developed. According to the mixed stirring washing machine, an agitator wash step of washing the laundry (W) only by the operation of the stirring rod (16), and the stirring rod (16) and the washing tank 14 are rotated at the same time to wash the laundry (W). A washing stroke in which a filtration wash step of washing is performed is performed.

상기 여과세정단계에서는 교반봉(16)과 세탁조(14)가 일측방향으로 동시에 빠른 속도로 회전함으로써 원심력에 의해 빨랫감(W)이 세탁조(14) 내벽에 밀착되고, 세탁수가 빨랫감(W)을 통과하여 세탁조(14)의 밖으로 빠져나가는 과정에서 빨랫감(W)에 묻어 있는 오염물질이 효과적으로 배출되기 때문에 보다 효율적인 세정작용이 이루어진다. In the filtration washing step, the stirring bar 16 and the washing tank 14 rotate at the same time in one direction at a high speed so that the laundry feeling W is adhered to the inner wall of the washing tank 14 by centrifugal force, and the washing water passes the washing feeling W. In the process of exiting the washing tank 14, since the contaminants buried in the clothes (W) is effectively discharged, more efficient cleaning is achieved.

즉, 상술한 바와 같은 혼합교반식 세탁기에 의하면 교반세정단계에 앞서 여과세정단계를 거치기 때문에 세정작용이 보다 효율적으로 진행된다는 이점이 있다.That is, according to the mixing stirring type washing machine as described above, since the filtration washing step is performed before the stirring washing step, there is an advantage that the washing operation proceeds more efficiently.

더불어, 이러한 종래의 세탁방법에서는 세정행정 초기에 적은 양의 세탁수를 미리 공급하여 여과세정작용을 수행하는 예비세정단계를 거치기도 하는데, 상기 예비세정단계에서는 세제의 함유비율이 높은 고농도의 세탁수를 사용하여 세제성분이 빨랫감(W)에 깊숙히 침투토록 한 다음, 여과세정 작동을 통해 빨랫감(W)에 묻은 오염물질을 1차적으로 여과하게 된다. 그리고, 상기 예비세정단계가 종료된 후에는 세탁수를 보충 급수한 상태에서 교반세정단계 및 여과세정단계를 거침으로써 잔류된 오염물질을 제거하고, 세정행정을 종료하게 된다.In addition, in the conventional washing method, a preliminary washing step of performing a filtration washing operation by supplying a small amount of washing water in advance at the beginning of the washing process is performed. In the preliminary washing step, high concentration washing water having a high content of detergent is used. Using to allow the detergent component to penetrate deeply into the clothes (W), and through the filtration cleaning operation to filter the contaminants attached to the clothes (W) first. After the preliminary washing step is completed, the remaining contaminants are removed by going through the stirring washing step and the filtration washing step in the state of supplemented water to wash water, and the washing operation is terminated.

한편, 이와 같은 예비세정단계를 거칠 경우에는 전술한 바와 같이 적은 양의 세탁수를 급수함으로써 세제의 함유비율을 높게 해야 하므로, 세제의 용해도를 높이기 위해 온수를 사용하는 것이 효과적인데, 종래기술에 의하면 세정행정전에 사용자가 반드시 온수가 급수되도록 온수밸브(302)의 작동을 지정해 주어야 한다. 이에 따라, 사용자의 부주의로 온수밸브(302)의 작동을 지정하지 않고 세정행정을 진행시킬 경우 예비세정단계에서 온수가 급수되지 않아 세탁수의 온도가 낮은 상태가 되기 때문에 세제가 제대로 용해되지 않고, 쉽게 포화상태에 도달하므로, 세제의 용해도가 낮은 저농도의 세탁수를 사용할 수 밖에 없는 등 예비세정단계에서의 세정효율을 높일 수 없다는 문제가 발생한다.On the other hand, when such a pre-cleaning step, as described above it is necessary to increase the content of the detergent by supplying a small amount of washing water, it is effective to use hot water to increase the solubility of the detergent, according to the prior art Before the cleaning stroke, the user must specify the operation of the hot water valve 302 so that hot water is supplied. Accordingly, when the washing stroke is proceeded without specifying the operation of the hot water valve 302 inadvertently, the detergent is not properly dissolved because hot water is not supplied in the preliminary washing step and the temperature of the washing water is low. Since it easily reaches a saturation state, there is a problem in that the cleaning efficiency in the pre-cleaning step cannot be increased, such as the use of low-concentration wash water having low solubility in detergents.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로, 예비세정단계 에서, 반드시 일정량의 온수를 급수토록 함으로써 세정효과가 향상되도록 하는 교반식 세탁기의 세탁방법 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, and in the preliminary washing step, it is an object of the present invention to provide a washing method of the stirring washing machine to improve the cleaning effect by supplying a certain amount of hot water.

상기 목적을 이루기 위하여 제공되는 교반식 세탁기의 세탁방법은 세탁조에 적은 양의 세탁수가 급수된 상태에서 교반봉과 세탁조가 빠르게 일체 회전하여 원심력에 의해 빨랫감이 세탁조 내벽에 압착되고 세탁수가 빨랫감을 통과함으로써 빨랫감이 세정되는 여과세정작동이 수행되는 예비세정단계와; 상기 예비세정단계가 종료된 후, 적정량의 세탁수가 보충 급수된 상태에서, 여과세정작동 및 교반봉의 정역 회전작동만으로 빨랫감이 세정되는 교반세정작동이 반복 수행되는 주세정단계가 조합된 세정행정을 포함하여 이루어지며, 상기 예비세정단계에서 일정량의 온수가 급수되도록 함으로써 세제의 용해도가 높아지도록 하는 것을 특징으로 한다.Washing method of agitated washing machine provided to achieve the above object is that the washing rod is quickly rotated integrally with the stirring rod and the washing tank in a state in which a small amount of washing water is supplied to the washing tank, and the feeling of washing is compressed by the centrifugal force and the washing water passes through the laundry. A preliminary washing step in which the filtration washing operation to be performed is performed; After the preliminary washing step is completed, in the state in which the appropriate amount of wash water is supplemented with water, a washing stroke including a main washing step in which a washing and washing operation in which a feeling of washing is repeatedly performed is performed only by filtration washing operation and forward / reverse rotation operation of the stirring rod. It is made, by the predetermined amount of hot water in the pre-cleaning step characterized in that the solubility of the detergent is increased.

이하, 본 발명의 실시예를 첨부된 도 3을 참조로 하여 상세하게 설명하며, 본 발명의 구성 중 종래구성과 동일한 부분에 대해서는 동일한 부호를 부여하고 그 설명을 생략하기로 한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying FIG. 3, and the same reference numerals will be given to the same parts as the prior art components of the configuration of the present invention and the description thereof will be omitted.

우선, 본 발명의 실시예에 따른 교반식 세탁기의 세탁방법은 예비세정단계와 주세정단계가 조합된 세정행정을 포함하여 이루어지는데, 상기 예비세정단계에서는 세탁조(14)에 적은 양의 세탁수가 급수된 상태에서 교반봉(16)과 세탁조(14)가 빠르게 일체 회전하여 원심력에 의해 빨랫감(W)이 세탁조(14) 내벽에 압착되고 세탁수가 빨랫감(W)을 통과함으로써 빨랫감(W)이 세정되는 여과세정작동이 수행된다.First, the washing method of the stirring washing machine according to an embodiment of the present invention includes a washing stroke in which a preliminary washing step and a main washing step are combined. In the preliminary washing step, a small amount of washing water is supplied to the washing tank 14. In the turned state, the stirring rod 16 and the washing tank 14 are quickly rotated together so that the laundry feeling W is pressed against the inner wall of the washing tank 14 by centrifugal force, and the washing water W is washed by passing the washing water W. The filtration cleaning operation is performed.

이와 같은 예비세정단계에서는 사용자의 선택과 무관하게 반드시 일정량의 온수가 공급됨으로써 세탁수의 온도를 상온 이상으로 유지하게 되는데, 이와 같이 하면, 세제의 용해도가 높아지기 때문에, 냉수만을 사용한 세탁수에 비해 많은 양의 세제가 용해된다. 따라서, 예비세정단계에서 여과세정작동 시의 세정효과가 향 상된다.In this pre-cleaning step, regardless of the user's choice, a certain amount of hot water must be supplied to maintain the temperature of the washing water above room temperature. Positive detergent is dissolved. Therefore, the cleaning effect during the filtration cleaning operation in the preliminary washing step is improved.

그리고, 예비세정단계에 이어서, 진행되는 주세정단계에서의 보충 급수시 냉수만이 공급되더라도, 세탁수의 온도가 일정수준 이상으로 유지되기 때문에 주세정단계에서의 세정효과 또한 향상된다. Then, after the preliminary washing step, even if only cold water is supplied during supplementary water supply in the main washing step, the washing effect in the main washing step is also improved because the temperature of the washing water is maintained at a predetermined level or more.

상기 주세정단계에서는 적정량의 세탁수가 보충 급수된 상태에서 여과세정작동과, 교반봉(16)의 정역 회전작동만으로 빨랫감(W)이 세정되는 교반세정작동이 반복 수행되는데, 세탁수가 재급수된 다음, 교반봉(16)만이 정역회전하는 교반세정단계가 진행되는데, 이때에는 이미 스핀세정단계에서 일차적인 세정작용이 완료된 상태이기 때문에 세탁수의 사용량을 종래의 세정행정에서 보다 현저히 줄일 수 있게 된다. In the main washing step, the filtration washing operation in the state that the appropriate amount of washing water is supplemented water and the stirring washing operation in which the laundry (W) is washed only by the forward and reverse rotation operation of the stirring rod 16 is repeatedly performed. In this case, only the stirring rod 16 rotates forward and backward, and the stirring washing step is progressed. At this time, since the first washing operation is completed in the spin washing step, the amount of washing water can be significantly reduced in the conventional washing stroke.

따라서, 상술한 바와 같은 본 발명의 실시예에 의하면 처음부터 교반세정작동이 가능한 정도의 많은 세탁수를 사용하지 않고, 적은 양의 세탁수를 사용하는 예비세정단계를 거치기 때문에, 종래에 비해 세탁수의 사용량이 감소되며, 주세정단계에서 보다 세제가 훨씬 높은 비율로 함유된 이른바 고농도 세탁수가 사용됨으로써 세정효과가 향상된다.Therefore, according to the embodiment of the present invention as described above, since the washing process is performed using a small amount of washing water without using as much washing water as possible to perform the washing and washing operation from the beginning, washing water compared with the conventional The amount of rinse is reduced, and the washing effect is improved by using so-called high concentration washing water containing much higher detergent ratio in the main washing step.

상술한 바와 같은 본 발명에 따른 교반식 세탁기의 세탁방법에 의하면, 예비세정단계에서 사용자의 지정과 상관없이 무조건 일정량의 온수를 사용하게 됨으로써 세제의 용해도가 냉수만을 사용할 경우보다 높아지기 때문에, 예비세정단계에서의 세정효과는 물론 주세정단계에서의 세정효과 또한 더불어 향상된다는 이점이 있 다.According to the washing method of the stirring washing machine according to the present invention as described above, since a certain amount of hot water is unconditionally used regardless of the user's designation in the preliminary washing step, the solubility of the detergent is higher than when only cold water is used, the preliminary washing step In addition to the cleaning effect in the main cleaning step, the cleaning effect is also improved.
