(See Figure 2)

상술한 바와 같이 구성된 교반식 세탁기의 제어방법은 급수밸브(17)에 의해 세탁조(14) 내로 세탁수가 급수되는 급수행정과, 급수행정 종료 후 도 6에 나타난 것과 같이 교반봉(16)의 회전 작동으로 세탁수와 빨랫감(W)을 일정 시간동안 교반시키는 세정행정과, 세정행정 종료 후 배수밸브(18)를 통해 세탁수를 배수한 다음, 세제가 함유되지 않은 맑은 물 즉, 헹굼수를 급수하여 일정 횟수만큼 빨랫감(W)을 헹구는 헹굼행정과, 헹굼행정 종료 후 세탁조(14)를 고속으로 회전시켜 빨랫감(W)을 탈수하는 탈수행정으로 이루어진다.The control 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 17, and the rotation of the stirring rod 16 as shown in FIG. 6 after the water supply stroke is finished. After washing the washing water and the feeling of washing (W) for a predetermined time, the washing water is drained through the drain valve 18 after the completion of the washing stroke, and then a predetermined number of times by supplying clean water containing no detergent, that is, rinsing water It consists of a rinsing stroke for rinsing the clothes (W) as much as, and a dehydration stroke for dehydrating the laundry (W) by rotating the washing tank 14 at high speed after the end of the rinsing stroke.

이와 같은 제어방법 중, 급수행정에서는 급수밸브(17)를 통해 유입되는 물이 세제통을 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(30)에 의해 그 회전방향이 간헐적으로 반전되는 정역회전을 반복함으로써 좌우방향 수류와 상하방향 수류가 조합된 양방향 수류를 형성하여 세정작용을 이루게 된다.In such a control method, in the water supply stroke, the water flowing through the water supply valve 17 passes through the detergent container, and the washing water mixed with the detergent is supplied, and in the washing stroke, the stirring rod (with the chemical action of the detergent contained in the washing water) 16) a washing action is performed in which the contaminants buried in the clothes (W) are removed by a physical action, wherein the stirring rod 16 is reversely rotated in which the rotation direction is intermittently reversed by the transmission 30. By repeating to form a bidirectional water flow combined with the left and right water flow and the up and down water flow to achieve a cleaning action.

이어서, 진행되는 헹굼행정에서는 세제가 혼합되지 않은 헹굼수가 공급된 상태에서 세정행정에서와 마찬가지로 교반봉(16)의 교반작동에 의해 발생하는 양방향 수류에 의해 빨랫감(W)에 묻어있는 세제성분이 제거되고, 탈수행정에서는 헹굼수가 배수된 다음, 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)와교반봉(16)이 동시에 같은 방향으로 회전함으로써 빨랫감(W)이 교반봉(16)에 걸려 훼손되는 것이 방지되며, 배수밸브(18)가 개방됨으로써 세탁조(14)의 누수홀(14a)을 통해 배출된 물기를 세탁기의 외부로 배수하게 된다.Subsequently, in the ongoing rinsing stroke, the detergent component buried in the clothes (W) is removed by the bidirectional water flow generated by the stirring operation of the stirring rod 16 as in the washing stroke in the state where the rinse water is not mixed with the detergent. In the dehydration stroke, the rinsing water is drained, and then the washing tank 14 rotates quickly in one direction so that the water of the clothes W is held by the centrifugal force in a state where the washing feeling W is in close contact with the inner wall of the washing tank 14. Exit through 14a). 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 the drain valve 18 is opened to wash the washing tank 14. The water discharged through the leak hole (14a) of the drain to the outside of the washing machine.

한편, 상술한 바와 같은 일반적인 교반식 세탁기에 의하면 교반봉(16)의 작동 특성상, 좌우방향의 수류와 함께 상하방향의 수류가 조합된 양방향 수류가 형성되므로 드럼식이나 와권식 세탁기에 비해 세탁과정에서 빨래감이 엉키지 않는 등의 이점이 있으나, 교반봉(16)과 빨래감이 마찰되기 때문에 빨래감의 손상이 심하고, 많은 양의 세탁수를 필요로 할 뿐만 아니라, 교반봉(16)의 작용만으로는 강한 수류를 형성할 수 없기 때문에 세탁력이 떨어진다는 단점 또한 발생한다.On the other hand, according to the general stirring type washing machine as described above, due to the operating characteristics of the stirring rod 16, the two-way water flow combined with the water flow in the left and right direction is formed in the washing process compared to the drum-type or spiral winding washing machine Although there is an advantage of not being entangled, since the stirring rod 16 and the laundry feeling are rubbed, damage to the laundry is severe, not only a large amount of washing water is required, but also a strong water flow is formed only by the action of the stirring rod 16. The disadvantage is that washing power is poor because it can not.

따라서, 상기 일반 교반식 세탁기의 단점을 보완하기 위하여, 도 7에 나타난 것과 같이 이른바 혼합교반식 세탁기(미국 특허등록번호 4,784,666)가 개발되었는데. 이러한 혼합교반식 세탁기에 의하면, 교반봉(16)의 작동만으로 빨래감을 세탁하는 교반세정(agitator wash)단계와, 교반봉(16)과 세탁조(14)가 동시에 회전하여 빨래감을 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 (US Pat. No. 4,784,666) was developed as shown in FIG. According to the mixed stirring washing machine, the agitator wash step of washing the laundry only by the operation of the stirring rod 16, and the filtration washing to wash the laundry by rotating the stirring rod 16 and the washing tank 14 at the same time ( A washing stroke combined with a filtration wash step is performed.

상기 여과세정단계는 교반세정단계에 앞서 진행되는데, 여과세정단계에서는 교반봉(16)과 세탁조(14)가 일측방향으로 동시에 빠른 속도로 회전함으로써 원심력에 의해 빨래감이 세탁조(14) 내벽에 밀착되고, 세탁수가 빨래감을 통과하여 세탁조(14)의 밖으로 빠져나가는 과정에서 빨래감에 묻은 오염물질이 효과적으로 배출되기 때문에 보다 효율적인 세정작용이 이루어진다.The filtration washing step is performed before the stirring washing step, in the filtration washing step, the stirring rod 16 and the washing tank 14 are rotated at the same time in one direction at a high speed so that the washing is adhered to the inner wall of the washing tank 14 by centrifugal force. In the process of washing water passing through the laundry and exiting the washing tank 14, the pollutants attached to the laundry are effectively discharged, thereby making the washing more efficient.

이와 같은, 여과세정단계에서는 세제가 교반세정단계에서 보다 훨씬 높은 비율(0.5 ∼ 4%)로 함유된 이른바 고농축 세탁수가 사용되어야 효과적인 세정작용을 이룰 수 있기 때문에 상대적으로 적은 양의 물을 사용하게 되고, 별도의 펌프(70) 및 이와 연결된 노즐기구(72)를 사용하여 세탁조(14) 밖으로 배출된 세탁수를 세탁조(14)로 되돌림으로써 세탁수의 사용효율을 높이게 된다.As such, in the filtration and washing step, relatively small amount of water is used because detergents are used at a much higher rate (0.5 to 4%) than so-called high concentration washing water to achieve effective cleaning. By using a separate pump 70 and the nozzle mechanism 72 connected thereto, the washing water discharged out of the washing tank 14 is returned to the washing tank 14 to increase the use efficiency of the washing water.

즉, 상술한 바와 같은 혼합교반식 세탁기에 의하면 교반세정단계에 앞서 여과세정 단계를 거치기 때문에 세정작용이 보다 효율적으로 진행되며, 여과세정 단계에서는 적은 양의 세탁수만으로도 세정작용이 수행되기 때문에 세탁수가 절약된다는 이점이 있다.That is, according to the mixing stirring type washing machine as described above, the washing operation proceeds more efficiently because the filtration washing step is performed before the stirring washing step, and the washing water is performed only with a small amount of washing water in the filtration washing step. There is an advantage to saving.

그러나, 이와 같은 종래의 혼합교반식 세탁기에 의하면 전술한 바와 같이 여과세정단계에서 세탁조(14) 밖으로 배출된 세탁수를 되돌리기 위하여, 펌프(70) 및 노즐기구(72)와 같은 별도의 구성요소를 필요로 하기 때문에 세탁기의 구조가 복잡해지고, 펌프(70)를 이용한 펌핑 작용 시 세탁수가 단순히 세탁조(14) 내로 순환만 될 뿐 세탁수 분사 시의 압력 등에 의해 세정에 기여하는 어떠한 작용도 이루어지지 않기 때문에 세정효율이 떨어진다는 문제가 발생한다.However, according to the conventional mixed stirring washing machine, as described above, in order to return the wash water discharged out of the washing tank 14 in the filtration and washing step, separate components such as the pump 70 and the nozzle mechanism 72 are provided. Since the structure of the washing machine becomes complicated, the washing water is simply circulated into the washing tank 14 during the pumping action using the pump 70, and no action is contributed to the washing by the pressure during washing water injection. This causes a problem of low cleaning efficiency.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로, 교반식 세탁기에 있어서, 교반봉의 정역회전을 통한 교반세정단계와, 교반봉와 세탁조의 동시 회전을 통한 여과세정단계를 포함하며, 여과세정단계에서 펌프 및 노즐기구와 같은 별도의 구성요소에 의하지 않고 세탁조의 회전에 의한 원심력만으로 세탁수를 세탁조로 순환시키고, 순환되는 세탁수가 빨래감에 강하게 분사되도록 하여 세정작용을 효율적으로 수행하는 교반식 세탁기의 세탁방법 제공을 목적으로 한다.The present invention has been made to solve the above conventional problems, in the stirring washing machine, including a stirring washing step through the forward and reverse rotation of the stirring rod, and filtration washing step through the simultaneous rotation of the stirring rod and the washing tank, in the filtration washing step Washing of an agitated washing machine that circulates the washing water to the washing tank only by the centrifugal force by the rotation of the washing tank without the separate components such as the pump and the nozzle mechanism, and performs the washing operation efficiently by allowing the circulating washing water to be strongly sprayed on the laundry.

It is characterized by increasing the cleaning power by inducing an effect such as creeping.

이하, 본 발명의 실시예를 첨부된 도 8을 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. 8, and the same reference numerals will be given to the same parts as the prior art configurations of the present invention and the description thereof will be omitted.

우선, 본 발명의 실시예에 따른 교반식 세탁기는 도면에 나타난 것과 같이 저수조(12)와 세탁조(14) 사이의 간극을 유로로 이용하게 되며, 이와 같은 유로를 통해 유동된 세탁수가 세탁조(14) 내로 분사되도록 그 선단이 약간 하향 절곡된 형태의 저수조 커버(13)를 구비한 구조로 이루어진다.First, the agitated washing machine according to the embodiment of the present invention uses the gap between the water storage tank 12 and the washing tank 14 as a flow path as shown in the drawing, and the washing water flowing through the flow path is washed in the washing tank 14. The tip is made of a structure having a reservoir cover 13 of the shape bent slightly downward to be injected into.

상술한 바와 같은 본 실시예에 따른 교반식 세탁기에 의하면, 세정행정이 시작될 경우, 먼저 교반봉(16)과 세탁조(14)가 동일 방향으로 빠르게 회전하여 원심력에 의해 빨래감(W)이 세탁조(14) 내벽에 압착된 상태에서, 농축된 세탁수가 빨래감(W)을 통과함으로써 빨래감(W)이 세정되는 여과세정단계가 진행되고, 이어서 교반봉(16)의 작동에 의한 교반세탁단계가 진행되는데, 상기 여과세정단계에서는 세탁조(14)의 빠른 회전에 의한 원심력만으로, 세탁수가 저수조(12)와 세탁조(14) 사이에 형성된 유로를 통해 세탁조(14)내로 순환된다.According to the agitating type washing machine according to the present embodiment as described above, when the washing stroke starts, the stirring rod 16 and the washing tank 14 are rapidly rotated in the same direction so that the laundry W is washed by the centrifugal force 14. In the compressed state on the inner wall, the washing step (W) is washed by the concentrated washing water passing through the laundry (W), and then the stirring washing step by the operation of the stirring rod 16 is performed, In the filtration washing step, the washing water is circulated into the washing tank 14 through a flow path formed between the water storage tank 12 and the washing tank 14 only by the centrifugal force due to the rapid rotation of the washing tank 14.

즉, 본 실시예에 의하면 여과세정단계에서의 세탁수 순환이 종래기술(미국 특허등록번호 4,784,666)에서처럼, 펌프(70) 및 노즐기구(72)(도 7 참조)와 같은 별도의 구성요소에 의해 이루어지는 것이 아니라, 세탁조(14)의 회전 시 발생하는 원심력만으로 수행되기 때문에, 세탁기의 구조를 단순화 할 수 있게 된다.That is, according to the present embodiment, the washing water circulation in the filtration and washing step is performed by separate components such as the pump 70 and the nozzle mechanism 72 (see FIG. 7), as in the prior art (US Patent No. 4,784,666). It is not made, but because only the centrifugal force generated during the rotation of the washing tank 14, it is possible to simplify the structure of the washing machine.

또한, 이와 같은 여과세정단계에서는 저수조 커버(13)의 구조상 세탁수가 순환되는 과정에서 세탁조(14)의 벽면에 밀착된 빨래감(W)을 향해 강하게 분사됨으로써 빨래감(W)을 두들기는 것과 같은 소위 수타(水打)작용이 유발된다. 이러한 수타작용은 세탁수를 이용한 일종의 물리적 세정작용으로서, 원심력에 의해 세탁수가 빨래감(W)을 통과하는 과정에서 세제에 의해 이루어지는 화학적 세정작용과 함께 효과적인 세정작용 수행에 큰 도움이 된다.In addition, in such a filtration cleaning step, so-called hand tapping such as tapping the laundry (W) by being strongly sprayed toward the laundry (W) in close contact with the wall surface of the washing tank 14 in the process of circulating the wash water in the structure of the water tank cover 13 (水 打) action is induced. This hand acting is a kind of physical cleaning using the washing water, which is very helpful in carrying out the effective cleaning action along with the chemical cleaning action by the detergent in the process of passing the washing water (W) by centrifugal force.

상술한 바와 같은 본 발명에 따른 교반식 세탁기의 세탁방법에 의하면, 교반봉와 세탁조가 동시 회전되는 여과세정단계에서, 순환되는 세탁수가 빨래감에 강하게 분사되도록 함으로써 보다 효과적인 세정작용을 수행할 수 있을 뿐만 아니라,펌프와 같은 별도의 구성요소에 의하지 않고 세탁조의 회전에 의한 원심력만으로 세탁수가 세탁조로 순환되기 때문에, 세탁기의 세정성능 및 제작효율 향상에 도움이 된다는 이점이 있다.According to the washing method of the stirring washing machine according to the present invention as described above, in the filtration washing step in which the stirring rod and the washing tank are rotated at the same time, it is possible to perform a more effective cleaning action by allowing the washing water to be circulated strongly to wash. The washing water is circulated to the washing tank only by the centrifugal force due to the rotation of the washing tank, not by a separate component such as a pump, and thus, there is an advantage that the washing performance and the manufacturing efficiency of the washing machine are improved.
