Description

드럼 세탁기 및 그 세탁/헹굼방법Drum washing machine and its washing / rinsing method

본 발명은 드럼 세탁기에 관한 것으로, 특히 원심력을 이용하여 세탁을 하는 드럼 세탁기 및 그 세탁/헹굼방법에 관한 것이다.The present invention relates to a drum washing machine, and more particularly, to a drum washing machine for washing using centrifugal force and a washing / rinsing method thereof.

알려진 세탁기의 종류로는 크게 펄세이터 세탁기, 봉 세탁기, 드럼 세탁기 등으로 구분되는데, 이 중에서 드럼 세탁기는 내조에 배플을 설치하고 물을 채워 그 내조를 다수회 정,역회전시키는 중에 세탁물이 배플에 걸려 상승하였다가 고점에서 떨어져 발생하는 충격력 및 세탁수에 함유된 세제에 의해 세탁이 되도록 하는 것으로, 도 1은 종래의 드럼 세탁기를 개략적으로 보인 종단면도이다.Known types of washing machines are classified into pulsator washing machines, rod washing machines, drum washing machines, etc. Among these, washing machines are installed with baffles in an inner tank and filled with water to rotate and wash the inner tank many times. It is to be washed by the detergent contained in the washing water and the impact force generated from rising to fall from the high point, Figure 1 is a longitudinal sectional view schematically showing a conventional drum washing machine.

이에 도시된 바와 같이 종래의 드럼 세탁기는, 세탁기 몸체(1)의 내부에 세탁조(2)가 설치되어 있고, 그 세탁조(2)의 내부에는 내조(3)가 회전가능하게 설치되어 있으며, 그 내조(3)의 내주면에는 수개(도면에선 4개)의 배플(4)이 돌출 형성되어 있다.As shown in the conventional drum washing machine, the washing tank 2 is installed inside the washing machine body 1, and the inner tank 3 is rotatably installed inside the washing tank 2, and the inner tank On the inner circumferential surface of (3), several baffles 4 are formed to protrude.

상기 세탁조(2)의 상반부 양측에는 세탁기 몸체(1)의 양측 모서리에 설치된 인장스프링부재(5)에 의해 탄력 지지되어 있는 반면, 하반부 양측에는 세탁기 몸체(1)의 양측 모서리에 설치된 댐퍼(6)에 얹혀져 지지되어 있다.Both sides of the upper half of the washing tank 2 is elastically supported by the tension spring member 5 installed at both edges of the washing machine body 1, while the lower half of the damper 6 is installed at both edges of the washing machine body 1 at both sides. It is mounted on and supported.

도면중 미설명 부호인 8은 배수관, 8a는 솔레노이드밸브이다.In the drawings, reference numeral 8 denotes a drain pipe, and 8a denotes a solenoid valve.

상기와 같이 구성된 종래 세탁기의 세탁/헹굼과정은 다음과 같다.The washing / rinsing process of the conventional washing machine configured as described above is as follows.

먼저, 세탁모드가 선택되면 세탁조(2) 부피의 약 60%정도가 되는 세탁수가 급수호스(7)를 통해 세제와 함께 세탁조(2)의 내부로 유입되고, 이어서 내조(3)가 통상 50 ~ 60 rpm의 저속회전을 약 20여분간 진행하여 그 내조(3)에 수납된 세탁물이 배플(4)에 의해 교반되면서 상반부쪽으로 이동을 하였다가 자중에 의해 자연낙하를 하면서 세탁물간의 비빔현상 및 낙하충격 그리고 세탁물에 함유된 세제에 의해 소정의 세탁이 이루어지게 되는 것이었다.First, when the washing mode is selected, the washing water, which is about 60% of the volume of the washing tank 2, flows into the inside of the washing tank 2 together with the detergent through the water hose 7, and then the inner tank 3 is usually 50 to 50. After the slow rotation of 60 rpm for about 20 minutes, the laundry stored in the inner tank (3) was moved to the upper half while being stirred by the baffle (4), and the natural falling by the weight of the bib phenomenon and drop impact between the laundry and The laundry contained in the laundry was subjected to predetermined washing.

다음, 상기 세탁기가 헹굼모드일 경우에는, 전술한 세탁모드와 동일한 과정을 거치게 되나, 세탁수에 세제가 배제된 상태로 급수되는 차이가 있다.Next, when the washing machine is in the rinsing mode, the washing machine is subjected to the same process as the washing mode described above, but there is a difference in that the washing water is supplied with the detergent removed.

여기서, 상기의 세탁모드나 또는 헹굼모드의 경우에, 한번 세탁조(2)로 유입되어 소정의 세탁 또는 헹굼을 마친 세탁/헹굼수는 배수관(8)을 통해 세탁기의 외부로 배출되고, 필요시 새로운 세탁/헹굼수가 재유입되어 전술한 세탁 또는 헹굼을 재진행하도록 되어 있다.Here, in the washing mode or the rinsing mode, the washing / rinsing water, which has once been introduced into the washing tank 2 and finished washing or rinsing, is discharged to the outside of the washing machine through the drain pipe 8, The wash / rinse water is reflowed to re-run the aforementioned wash or rinse.

그러나, 상기와 같은 종래의 드럼 세탁기는, 세탁물을 상측에서 하측으로 자연낙하시켜 기계적인 충격력을 발생시키고 그 충격력을 이용하여 세탁을 실시하는 것이나, 실제 내조(3)의 직경이 세탁물의 양에 비해 충분히 크지 못하여 세탁물의 자연낙하시 발생되는 충격력이 미비하게 되고, 이로 인해 장시간 세탁을 진행하게 되어 세탁시간이 지나치게 길어지며, 세탁물이 배플 등에 의해 포손상이 발생되어 섬세한 의류에는 그 사용이 제한되는 등의 문제점이 있었다.However, in the conventional drum washing machine as described above, the laundry is naturally dropped from the upper side to the lower side to generate a mechanical impact force, and washing is performed using the impact force, but the diameter of the inner tub 3 is compared with the amount of the laundry. It is not large enough, and the impact force generated by natural fall of laundry is insufficient. As a result, washing is performed for a long time, and the washing time is excessively long. Foam damage occurs due to baffles, etc., which limits the use of delicate clothes. There was a problem.

또한, 상기 세탁조(2)에 초기 급수되는 세탁수가 과다하게 공급되어야 하므로, 세탁수의 과소비가 발생하고 나아가 환경이 오염되는 문제점도 있었다.In addition, since the wash water initially supplied to the washing tank 2 is excessively supplied, excessive consumption of the wash water occurs, and there is a problem that the environment is contaminated.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로, 세탁기를 대형화하지 않고도 충분한 세탁력을 발생시켜 세탁시간을 현저하게 단축하며, 세탁물에 기계적인 마찰을 가하지 않도록 하여 포손상을 방지하므로 섬세한 의류 등에도 다양하게 사용할 수 있는 드럼 세탁기를 제공하려는데 본 발명의 목적이 있다.Therefore, the present invention has been made in view of the above problems, it generates a sufficient washing power without increasing the size of the washing machine to significantly shorten the washing time, and does not apply mechanical friction to the laundry to prevent damage to delicate clothing It is an object of the present invention to provide a drum washing machine that can be used in various ways.

또한, 세탁에 필요한 세탁수의 양을 절감하는 것은 물론, 환경친화적인 드럼 세탁기를 제공하려는데도 본 발명의 목적이 있다.In addition, it is an object of the present invention to reduce the amount of wash water required for washing, as well as to provide an environmentally friendly drum washing machine.

도 2는 본 발명에 의한 드럼 세탁기의 일례를 개략적으로 보인 종단면도이다.2 is a longitudinal sectional view schematically showing an example of a drum washing machine according to the present invention.

이에 도시된 바와 같이 본 발명에 의한 드럼 세탁기는, 세탁기 본체(11)의 내부에 세탁조(12)가 상반부는 인장코일스프링(S)에 걸려 탄력 지지되는 반면 하반부는 댐퍼(D)에 고정되도록 설치되고, 그 세탁조(12)의 내부에는 세탁물이 담기는 내조(13)가 회전가능하게 설치되며, 상기 세탁조(12)의 하측에는 솔레노이드밸브(14a)에 의해 차별적으로 개폐되는 배수관(14)이 세탁조(12)와 연통되어 세탁/헹굼수를 일시 저장하는 저장조(15)가 설치되고, 상기 세탁기 본체(11)의 바닥측에는 저장조(15)에 담수된 세탁/헹굼수를 적당량 흡입하여 다시 세탁조(12)로 토출시키거나 또는 세탁기 본체(11)의 외부로 배출시키는 급수펌프(16)가 설치되는 것을 포함하여 구성된다.As shown in the drum washing machine according to the present invention, the washing tank 12 is installed inside the washing machine main body 11 so that the upper half is elastically supported by the tension coil spring S while the lower half is fixed to the damper D. The inside of the washing tank 12, the inner tank 13 for storing the laundry is rotatably installed, the lower side of the washing tank 12, the drain pipe 14 which is opened and closed by the solenoid valve 14a is a washing tank A storage tank 15 is installed in communication with 12 to temporarily store the washing / rinsing water, and a washing tank 12 is sucked into the bottom side of the washing machine main body 11 by sucking an appropriate amount of washing / rinsing water fresh from the storage tank 15.

여기서, 상기 저장조(15)는 세탁기 본체(11)의 바닥면에 고정 설치하는 것이 바람직하나, 경우에 따라서는 세탁기 본체(11)의 외부에 별도로 설치하더라도 무방하다.Here, the storage tank 15 is preferably fixed to the bottom surface of the washing machine main body 11, in some cases may be separately installed outside the washing machine main body (11).

도며중 미설명 부호인 17은 급수통, 18은 급수관 또는 급수호스, 19는 배수관, 19a는 솔레노이드 밸브이다.17 is a water tank, 18 is a water pipe or a water hose, 19 is a drain pipe, and 19a is a solenoid valve.

상기와 같이 구성되는 본 발명에 의한 드럼 세탁기를 이용하여 세탁을 실시하는 과정은 다음과 같다.The process of washing using the drum washing machine according to the present invention configured as described above is as follows.

먼저, 세탁기의 세탁모드가 선택되면, 세탁물이 충분히 적셔질 수 있을 만큼의 세탁수가 급수통(17)으로부터 세탁조(12)에 공급되고, 이어서 상기 세탁조(12)에 공급되는 세탁수가 세탁물에 골고루 배이도록 내조(13)가 약 20초동안 50 ~ 60 rpm의 저속으로 회전을 한 이후에, 상기 세탁물에 배인 세탁수가 오염물과 함께 원심력에 의해 배출되도록 내조(13)가 일정시간동안 약 800 ~ 1200 rpm의 속도로 회전한다.First, when the washing mode of the washing machine is selected, washing water is supplied from the water supply tank 17 to the washing tank 12 so that the laundry can be sufficiently wetted, and then the washing water supplied to the washing tank 12 is evenly distributed to the laundry. After the inner tub 13 rotates at a low speed of 50 to 60 rpm for about 20 seconds, the inner tub 13 is about 800 to 1200 rpm for a predetermined time so that the washing water drained to the laundry is discharged by centrifugal force together with the contaminants. Rotate at speed.

상술한 과정을 거쳐 일차로 세탁을 실시한 다음에는 내조(13)의 회전이 중지된 상태에서 세탁조(12)와 저장조(15) 사이의 솔레노이드 밸브(14a)가 열려 세탁을 마친 세탁수가 저장조(15)로 배출되고, 이러한 세탁수의 배출이 종료되면 상기 세탁조(12)와 저장조(15) 사이의 솔레노이드밸브(14a)가 닫힘과 아울러 급수펌프(16)가 동작되어 저장조(15)의 세탁수가 급수통(17)으로 이동된 후 다시 세탁조(12)로 공급되고 나서, 내조(13)는 다시 저속으로 회전하는 등의 이후작업을 연속적으로 수회 반복 수행하는 것이다.After the first washing through the above-described process, the solenoid valve 14a between the washing tank 12 and the storage tank 15 is opened while the rotation of the inner tank 13 is stopped, and the washing water having finished washing is stored in the storage tank 15. When the discharge of the wash water is finished, the solenoid valve 14a between the washing tank 12 and the storage tank 15 is closed, and the water supply pump 16 is operated to wash the water in the storage tank 15. After being moved to (17) and again supplied to the washing tank 12, the inner tank 13 is to perform the subsequent operations such as rotating again at a low speed several times in succession.

한편, 상기 세탁기가 헹굼모드일 경우에는 전술한 세탁모드와 동일한 과정을 거치면서 세탁물에 대한 헹굼작업을 수행하게 되나,On the other hand, when the washing machine is in the rinsing mode, the same process as the above-described washing mode is performed to rinse the laundry, but

여기서, 상기 세탁모드와 헹굼모드의 다른 점은 상기 초기급수, 즉 세탁조(12)의 세탁수 또는 헹굼수를 공급하는 단계에서 세탁모드시는 세탁물량이 차지하는 부피의 두 배와, 세탁조(12)와 내조(13) 사이의 부피를 더한 양만큼의 세탁수를 공급하는 반면, 헹굼모드시에는 세탁물량이 차지하는 부피와, 세탁조(12)와 내조(13) 사이의 부피를 더한 양만큼의 세탁수를 공급하는 것인데, 이처럼 상호 초기급수량이 다른 이유는 헹굼모드시의 세탁물은 이미 어느정도 물이 적셔져 있기 때문이다.Here, the difference between the washing mode and the rinsing mode is that the initial water supply, that is, in the step of supplying the washing water or the rinsing water of the washing tank 12, in the washing mode twice the volume occupied by the laundry amount, and the washing tank 12 While the amount of the wash water plus the volume between the inner tank 13 and the inner tank 13 is supplied, in the rinsing mode, the amount of the washing water occupies the amount of the washing water plus the volume between the washing tank 12 and the inner tank 13. This is because the mutual initial water supply is different because the laundry in the rinse mode is already wet to some extent.

이와 같이, 상기 내조(13)에 배플을 제거하여 세탁물에 기계적인 충격력을 배제하는 대신에 원심력을 이용하여 세탁 및 헹굼을 실시하므로, 세탁물의 포손상을 현저하게 감소시킬 수 있게 되어 섬세한 의류등의 세탁도 가능하게 되는 것은 물론, 한 번 사용한 세탁/헹굼수를 다시 순환시켜 재사용하므로 세탁/헹굼수의 낭비를 혁신적으로 감축시킬 수 있게 되는 것이다.Thus, instead of removing the baffle in the inner tank 13 to remove the mechanical impact force on the laundry, washing and rinsing is performed using centrifugal force, thereby significantly reducing the damage to the laundry. In addition to being able to wash, the laundry / rinsing water used once is circulated again and reused, thus reducing the waste of washing / rinsing water.

이상에서 설명한 바와 같이 본 발명에 의한 드럼 세탁기는, 세탁기 본체와, 그 세탁기 본체의 내부에 고정 설치되는 세탁조와, 그 세탁조의 내부에 회전가능하게 설치되는 내조와, 상기 세탁조의 외부에 배수관으로 연통되도록 설치되어 그 세탁조와 차별적으로 개폐되면서 일차 세탁/헹굼을 마친 세탁/헹굼수가 일시 저장되는 저장조와, 그 저장조에 담수된 세탁/헹굼수를 적당량 흡입하여 다시 세탁조로 토출시키거나 또는 배출시키는 급수펌프를 포함하여 구성함으로써, 세탁물의 포손상을 현저하게 감소시킬 수 있게 되어 섬세한 의류등의 세탁도 가능하게 되는 것은 물론, 세탁/헹굼수의 낭비를 혁신적으로 감축시킬 수 있게 되는 효과가 있다.As described above, the drum washing machine according to the present invention communicates with the washing machine main body, a washing tank fixedly installed inside the washing machine main body, an inner tank rotatably installed inside the washing tank, and a drain pipe outside the washing tank. The water supply pump is installed so as to be opened and closed differently from the washing tank and temporarily stores the washing / rinsing water after the first washing / rinsing, and the washing / rinsing water freshened in the storage tank is discharged or discharged to the washing tank again. By including the configuration, it is possible to significantly reduce the damage of the laundry, thereby enabling the washing of delicate clothes and the like, as well as the effect of innovatively reducing the waste of washing / rinsing water.
