본 발명은 세탁기에 관한 것으로서, 더 상세하게는 세탁 및 헹굼시 사용되는 물의 양을 줄일 수 있도록 한 절수(節水)형 세탁기에 관한 것이다.The present invention relates to a washing machine, and more particularly, to a water-saving washing machine to reduce the amount of water used during washing and rinsing.

일반적으로, 세탁기는 세탁물에 묻은 때나 더러운 물질을 화학적인 분해작용과 기계적인 충격작용에 의해 제거하는 기기이다.Generally, a washing machine is a device that removes dirty or dirty substances from laundry by chemical decomposition and mechanical impact.

도 1과 도 2에 도시된 바와 같이, 세탁기는 본체(1)와, 상기 본체 내에댐퍼(5)에 의해 지지된 외조(2)와, 상기 외조 내에 회전 가능하게 설치되며 세탁물을 넣을 수 있는 원통형상의 내조(3)와, 상기 내조에 회전력을 인가시키는 구동장치(4)로 크게 나뉘어진다.1 and 2, the washing machine has a main body 1, an outer tub 2 supported by a damper 5 in the main body, and a cylindrical cylinder rotatably installed in the outer tub for storing laundry. It is largely divided into the inner tank 3 of an upper body, and the drive device 4 which applies a rotational force to the inner tank.

이와 더불어, 상기 내조(3)로 세탁수를 공급시키는 급수장치(6)와, 상기 내조의 물을 외부로 제거시키는 배수장치(7)가 포함되어 구성된다.In addition, a water supply device 6 for supplying the washing water to the inner tank 3, and a drainage device 7 for removing the water in the inner tank to the outside is configured.

여기서, 상기 구동장치(4)는 로터(4a)와 스테이터(4b)에 의해 발생한 동력이 내조축(3a)에 직접 전달되도록 구성된 것과, 상기 내조축에 설치된 풀리(도시생략)와, 상기 외조하단 일측에 장착된 모터(도시생략)를 상호 밸트(도시생략)로 연결하여 상기 모터에 의해 발생된 동력이 상기 내조축(3a)에 전달되도록 구성된 것과, 그 외 다양한 방법에 의해 동력이 내조축에 전달되도록 구성된 것이 있다.Here, the drive device 4 is configured such that the power generated by the rotor 4a and the stator 4b is directly transmitted to the inner tubular shaft 3a, a pulley (not shown) installed in the inner tubular shaft, and the outer tub bottom. A motor (not shown) mounted on one side is connected to each other by a belt (not shown), so that power generated by the motor is transmitted to the inner shaft 3a, and power is supplied to the inner shaft by various other methods. There is one configured to be delivered.

그리고, 상기 세탁기는, 세탁방식에 따라, 상기 내조(3)가 직접 회전하면서 세탁을 수행하는 내조 구동형 세탁기와, 상기 내조는 고정된 상태로써 내조 내부 바닥면에 구비된 펄세이터(도시생략)가 회전하면서 세탁을 수행하는 펄세이터 구동형 세탁기와, 그 외 다양한 세탁기로 구별된다.The washing machine includes an inner tank driving type washing machine in which the inner tank 3 directly rotates according to a washing method, and a pulsator (not shown) provided on the inner bottom surface of the inner tank in a fixed state. It is divided into a pulsator-driven washing machine that performs washing while rotating, and various other washing machines.

상기와 같이 이루어진 세탁기는 세탁행정, 헹굼행정, 그리고 탈수행정 순으로 동작을 수행하는데, 특히, 내조 구동형 세탁기를 토대로 각 행정에 대해 더 상세히 설명하면 다음과 같다.The washing machine configured as described above performs operations in the order of the washing stroke, the rinsing stroke, and the dehydrating stroke. In particular, the washing machine will be described in more detail based on the inner tank driven washing machine.

첫째, 세탁행정은, 급수장치(6)를 동작시켜 내조(3)로 물을 공급하는 급수단계와, 구동장치(4)를 동작시켜 내조의 회전에 의해 발생되는 수류의 투과력 및 세제의 분해작용을 이용함과 더불어 내조의 정ㆍ역 구동에 의해 발생되는 수류의 마찰력을 이용하여 내조 내에 위치한 세탁물을 세탁하는 세탁단계와, 상기 배수장치(7)를 동작시켜 상기 내조 내의 오염수를 외부로 빼내는 배수단계와, 구동장치의 로터(4a)를 고속 구동시켜 내조의 고속회전에 의해 발생되는 원심력을 이용하여 세탁물에 묻어 있는 오염수를 제거하는 탈수단계가 순차적으로 진행되어 이루어진다.First, the washing stroke, the water supply step of supplying water to the inner tank 3 by operating the water supply device 6, the operation of the drive unit 4 and the decomposition action of the water permeability and detergent generated by the rotation of the inner tank In addition, the washing step of washing the laundry located in the inner tank by using the frictional force of the water flow generated by the forward and reverse driving of the inner tank, and the drainage to drain the contaminated water in the inner tank to the outside by operating the drainage device 7 Step and the dehydration step of removing the contaminated water on the laundry by using the centrifugal force generated by the high-speed rotation of the inner tank by driving the rotor 4a of the drive at high speed is carried out sequentially.

둘째, 헹굼행정은, 급수장치(6)를 동작시켜 내조(3)에 물을 공급하는 급수단계와, 구동장치(4)를 동작시켜 내조의 회전에 의해 발생되는 수류를 이용하여 상기 세탁물에 묻어 있는 세제 및 때를 완전하게 제거하는 헹굼단계와, 배수장치(7)를 동작시켜 내조 내의 오염수를 외부로 빼내는 배수단계와, 구동장치의 로터(4a)를 고속 구동시켜 내조의 고속회전에 의해 발생되는 원심력을 이용하여 세탁물에 묻어 있는 오염수를 제거하는 탈수단계가 순차적으로 진행되되 필요에 따라 상기 단계들이 수회 반복되며 이루어진다.Second, the rinsing stroke is buried in the laundry using the water supply step of supplying water to the inner tank 3 by operating the water supply device 6 and the water flow generated by the rotation of the inner tank by operating the driving device 4. A rinsing step to completely remove any detergent and dirt present, a drainage step of draining the contaminated water to the outside by operating the drainage device 7, and driving the rotor 4a of the driving device at a high speed by high-speed rotation of the inner bath. The dehydration step of removing the contaminated water on the laundry using the centrifugal force generated is sequentially performed, but the steps are repeated several times as necessary.

셋째, 탈수행정은, 구동장치(4)의 로터(4a)를 고속 구동시켜 내조(3)의 고속회전에 의해 발생되는 원심력을 이용하여 세탁물에 묻어 있는 물기를 소정량 제거하는 탈수단계와, 배수장치(6)를 동작시켜 내조의 물을 제거하되 상기 탈수단계와 동시에 진행되는 배수단계가 포함되어 이루어진다.Third, the dehydration operation is a dehydration step of driving the rotor 4a of the drive device 4 at high speed to remove a predetermined amount of water from the laundry by using the centrifugal force generated by the high speed rotation of the inner tank 3, and drainage. Operation of the device 6 includes the removal of the water in the inner tank but includes a drainage step that proceeds simultaneously with the dehydration step.

하지만, 상기와 같이 이루어진 종래기술에 따른 세탁기는 다음과 같은 문제를 가지고 있다.However, the washing machine according to the prior art made as described above has the following problems.

탈수시(탈수단계 진행시), 내조(3)내에 있는 세탁물의 물기가 원심력을 받아 외조로 유동되도록 내조에 일률적으로 탈수공(3b)이 형성되어 있는데, 이로 인해세탁시(세탁단계 진행시) 또는 헹굼시(헹굼단계 진행시) 과다한 세탁수를 사용하게 되는 문제점이 있다.At the time of dehydration (during dehydration step), dehydration holes (3b) are uniformly formed in the inner tank so that the water in the inner tank (3) flows to the outer tank under centrifugal force. Or when rinsing (when proceeding with the rinsing step) there is a problem in that excessive wash water is used.

즉, 세탁시(세탁단계 진행시) 또는 헹굼시(헹굼단계 진행시) 내조(3)내의 세탁수가 탈수공(3b)을 통과하여 외조(2)와 내조(3) 사이에 형성된 간극부(8)로 유동하게 되는데, 이때 간극부로 유동된 세탁수는 세탁물을 세탁하거나 헹굼할 때 전혀 도움을 주지 못하는 것으로서, 단지 물 사용량을 증가시키는 역할을 하여, 소비자에게 과다한 비용을 안겨주는 문제가 있다.That is, when washing (when the washing step proceeds) or rinsing (when the rinsing step proceeds), the washing water in the inner tank 3 passes through the dehydration hole 3b to form a gap portion 8 formed between the outer tank 2 and the inner tank 3. In this case, the washing water flowing into the gap does not help at all when washing or rinsing the laundry, and only serves to increase water consumption, thereby causing excessive cost to the consumer.

본 발명은 종래기술에 대한 문제점을 해결하기 위한 것으로서, 세탁기의 구조를 절수(節水)형 구조로 개선하여, 내조와 외조 사이의 간극부에 존재하는 세탁수의 양을 현저하게 줄임과 더불어, 이에 따른 물사용 비용을 줄이는데 그 목적이 있다.The present invention is to solve the problem of the prior art, by improving the structure of the washing machine to a water-saving structure, significantly reducing the amount of wash water present in the gap between the inner tank and the outer tank, The purpose is to reduce the cost of using water.

상기 목적을 달성하기 위해서, 본 발명은, 내조와 외조가 구비된 세탁기에 있어서, 상기 내조와 상기 외조 사이에 형성되는 간극부 내에 존재하는 세탁수량이 저감되도록, 상기 간극부 내에 존재하는 세탁수를 상기 내조로 재순환시키는 펌핑수단이 포함되어 이루어짐을 특징으로 하는 절수형 세탁기를 제공한다.In order to achieve the above object, the present invention, in the washing machine provided with the inner tank and the outer tank, washing water present in the gap portion so as to reduce the amount of washing water present in the gap formed between the inner tank and the outer tank. It provides a water-saving washing machine comprising a pumping means for recycling to the inner tank.

이하, 첨부도면을 참조하여, 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 3은 본 발명에 따른 절수형 세탁기를 나타낸 도 1의 Ⅰ-Ⅰ단면도이다.3 is a cross-sectional view taken along line II of FIG. 1 showing a water-saving washing machine according to the present invention.

도면 설명에 앞서, 세탁기의 구성은 종래기술에 언급된 바 있으므로, 그 설명을 생략하고, 종래기술과 동일한 구조에 한해서는 종래와 동일한 부호를 부여키로 한다.Prior to the description of the drawings, since the configuration of the washing machine has been mentioned in the prior art, the description thereof will be omitted, and only the same structure as in the prior art will be given the same reference numeral as in the prior art.

본 발명에 따른 절수형 세탁기는, 도 3에 도시된 바와 같이, 내조(3)와 외조(2)가 구비된 세탁기에 있어서, 상기 내조와 상기 외조 사이에 형성되는 간극부(8) 내에 존재하는 세탁수량이 저감되도록, 상기 간극부 내에 존재하는 세탁수를 상기 내조로 재순환시키는 펌핑수단이 포함되어 이루어진다.The water-saving washing machine according to the present invention, as shown in Figure 3, in the washing machine provided with the inner tank (3) and the outer tank (2), which is present in the gap (8) formed between the inner tank and the outer tank In order to reduce the amount of wash water, pumping means for recycling the wash water existing in the gap portion to the inner tank is included.

이 때, 상기 펌핑수단은, 상기 외조(2) 하단에 장착된 배수관(7a)에 구비되어 세탁 및 헹굼시 동작되는 펌프(11)와, 상기 펌프에 일단이 연결되고, 타단이 상기 내조(3)의 상부에 위치하여 상기 펌프에 의해 펌핑된 세탁수를 상기 내조로 안내하는 안내유로(12)가 포함되어 이루어질 수 있다.At this time, the pumping means is provided in the drain pipe (7a) mounted to the lower end of the outer tank (2) and the pump 11 is operated when washing and rinsing, one end is connected to the pump, the other end is the inner tank (3) Located at the top of the) may be made to include a guide passage 12 for guiding the wash water pumped by the pump to the inner tank.

이와 더불어, 상기 펌핑수단은, 상기 안내유로(12)의 타단에 구비되어, 상기 내조(3)로 펑핑되는 세탁수에 분사력이 인가되도록 하여, 상기 내조 내의 세탁물에 세탁력 및 헹굼력을 부가시키는 노즐(13)이 더 포함되어 이루어짐이 바람직하다.In addition, the pumping means is provided at the other end of the guide passage 12, so that the spraying force is applied to the washing water that is popped into the inner tank (3), the nozzle for adding a washing force and rinsing force to the laundry in the inner tank It is preferable that 13 is further included.

한편, 상기 내조(3)는, 세탁 및 헹굼시, 상기 내조에서 상기 간극부(8)로 유출되는 세탁수의 양이 저감되도록 함과 동시에, 탈수시 상기 내조의 세탁수가 상기 간극부로 원활하게 유출되도록 상기 내조의 벽면에 형성되는 탈수공(3b)의 크기가 소정량 감소된 절수구조를 가짐이 바람직하다. 여기서, 상기 내조(3)의 절수구조를 위해, 상기 탈수공(3b)은 상기 내조의 벽면을 따라 하부로 갈수록 그 크기가 감소되는 형태를 취할 수 있다.On the other hand, the inner tank (3), while washing and rinsing, the amount of wash water flowing out of the inner tank to the gap portion 8 is reduced, and at the same time, the washing water of the inner tank smoothly flows into the gap portion during dehydration It is preferable to have a water-saving structure in which the size of the dewatering hole 3b formed on the wall surface of the inner tank is reduced by a predetermined amount. Here, for the water-saving structure of the inner tank 3, the dehydration hole (3b) may take the form of decreasing in size toward the bottom along the wall surface of the inner tank.

즉, 제1 행의 탈수공의 크기가 1이라면, 상기 내조(3)의 벽면에 형성된 탈수공의 행수(N)에 따라, 각 행(n)의 탈수공의 크기는,을 만족하여 이루어질 수 있다.That is, if the size of the dehydration hole of the first row is 1, the size of the dewatering hole of each row n is according to the number of rows N of the dewatering holes formed on the wall surface of the inner tank 3, It can be achieved by satisfying.

예를 들어, 상기 식에 의하면, 상기 내조(3)의 벽면에 형성된 탈수공(3b)이 2행으로 배열되어 있고, 제1 행의 탈수공의 직경이 1이라면, 제2 행의 탈수공의 직경은 1/2임을 의미하고, 상기 내조의 벽면에 형성된 탈수공이 3행으로 배열되어 있고, 제1 행의 탈수공의 직경이 1이라면, 제2 행의 탈수공의 직경은 2/3이고, 제3 행의 탈수공의 직경은 1/3임을 의미하며, 그리고, 상기 내조의 벽면에 형성된 탈수공이 10행으로 배열되어 있고, 제1 행의 탈수공의 직경이 1이라면, 제2 행의 탈수공의 직경은 9/10, ...., 제10 행의 탈수공의 직경은 1/10임을 의미한다.For example, according to the above formula, if the dewatering holes 3b formed on the wall surface of the inner tank 3 are arranged in two rows, and the diameter of the dewatering holes in the first row is 1, The diameter means 1/2, and if the dewatering holes formed in the wall of the inner tank are arranged in three rows, and the diameter of the dewatering holes in the first row is 1, the diameter of the dewatering holes in the second row is 2/3, The diameter of the dehydration hole of the third row means 1/3, and if the dewatering holes formed on the wall surface of the inner tank are arranged in ten rows, and the diameter of the dewatering hole of the first row is one, the dehydration of the second row The diameter of the ball is 9/10, ...., means that the diameter of the dewatering hole in the tenth row is 1/10.

다른 한편, 상기 내조(3)는, 세탁 및 헹굼시, 상기 내조에서 상기 간극부(8)로 유출되는 세탁수의 양이 저감되도록 함과 동시에, 탈수시 상기 내조의 세탁수가 상기 간극부로 원활하게 유출되도록 상기 내조의 벽면에 형성되는 탈수공(3b)의 개수가 소정량 감소된 절수구조를 가짐이 바람직하다. 여기서, 상기 탈수공은, 내조의 벽면을 따라 하부로 갈수록 그 개수가 감소되는 형태를 취할 수 있다.On the other hand, the inner tank (3), when washing and rinsing, so that the amount of wash water flowing out of the inner tank to the gap portion 8 is reduced, and at the same time, the washing water of the inner tank during dehydration smoothly into the gap portion It is preferable to have a water-saving structure in which the number of dewatering holes 3b formed in the wall surface of the inner tank is reduced by a predetermined amount so as to flow out. Here, the dehydration hole may have a form in which the number thereof decreases toward the bottom along the wall surface of the inner tank.

즉, 제1 행의 탈수공(3b)의 개수가 15라면, 상기 내조(3)의 벽면에 형성된 탈수공의 행수(N)에 따라, 각 행(n)의 탈수공의 개수는,을 만족하여 이루어질 수 있다.That is, if the number of the dehydration holes 3b of the first row is 15, the number of the dehydration holes of each row n is determined according to the number of rows N of the dehydration holes formed on the wall surface of the inner tank 3, It can be achieved by satisfying.

예를 들어, 상기 식에 의하면, 상기 내조(3)의 벽면에 형성된 탈수공(3b)이2행으로 배열되어 있고 제1 행의 탈수공의 개수가 15라면, 제2 행의 탈수공의 개수는임을 의미하고, 상기 내조의 벽면에 형성된 탈수공이 3행으로 배열되어 있고 제1 행의 탈수공의 개수가 15라면, 제2 행의 탈수공의 개수는이고, 제3 행의 탈수공의 개수는임을 의미하며, 그리고, 상기 내조의 벽면에 형성된 탈수공이 10행으로 배열되어 있고 제1 행의 탈수공의 개수가 15라면, 제2 행의 탈수공의 개수는,...., 제10 행의 탈수공의 개수는임을 의미한다. 그리고, 여기서 계산되어진 값 중 소수점 이하의 값은 버릴 수도 있고 반올림하여 탈수공의 개수를 구할 수 있다.For example, according to the above formula, if the dewatering holes 3b formed on the wall surface of the inner tank 3 are arranged in two rows and the number of the dewatering holes in the first row is 15, the number of dewatering holes in the second row Is If the dehydration hole formed in the wall of the inner tank is arranged in three rows and the number of dewatering holes in the first row is 15, the number of dehydration holes in the second row is And the number of dehydration holes in the third row is And, if the dewatering holes formed in the wall of the inner tank is arranged in 10 rows and the number of dewatering holes in the first row is 15, the number of dewatering holes in the second row is , ...., the number of dehydration holes in the tenth row Means. And, the value below the decimal point among the calculated values may be discarded or rounded to obtain the number of dehydration holes.

이와 더불어, 상기와 같이 내조(3)에 형성된 탈수공(3b)의 크기 및 개수를 조절함과 함께, 상기 탈수공이 상기 내조의 하단에는 구비되지 않도록 함이 바람직하다. 즉, 탈수공이 내조에 형성되는 이유가, 탈수시 세탁물에 흡수된 세탁수를 내조 둘레 방향을 갖는 원심력을 이용하여 상기 간극부(8)로 유동되도록 하기 위한 통과공이기 때문에, 구지 원심력의 방향과 관계없는 내조의 하단에 상기 탈수공을 형성시킬 필요가 없으며, 만약 내조의 하단에 탈수공을 형성시키게 되면 세탁 또는 헹굼시 상기 탈수공을 통해 세탁수가 빠져나게 되어 본 발명의 취지를 약화시킬 수 있기 때문이다.In addition, while controlling the size and number of the dehydration hole (3b) formed in the inner tank 3 as described above, it is preferable that the dehydration hole is not provided at the lower end of the inner tank. That is, the reason why the dewatering hole is formed in the inner tank is the through-hole for allowing the wash water absorbed by the laundry to be dehydrated to flow to the gap portion 8 by using the centrifugal force having the inner tank circumferential direction. It is not necessary to form the dehydration hole at the bottom of the irrelevant inner tub, and if the dehydration hole is formed at the bottom of the inner tub, the wash water is drained through the dehydration hole during washing or rinsing, thereby weakening the gist of the present invention. Because.

상기와 같이 이루어진 본 발명은 다음과 같은 동작을 수행한다.The present invention made as described above performs the following operation.

세탁시(세탁단계 진행시) 또는 헹굼시(헹굼단계 진행시) 펌프(11)를 구동시켜 간극부(8)의 세탁수를 안내유로(12)로 토출시키고, 안내유로로 토출된 세탁수는 안내유로를 따라 내조(3) 상부로 유동하게 된다. 그리고 세탁수는 안내유로 끝단에 구비된 노즐(13)을 통해 내조 내로 분사되게 된다.When washing (when the washing step is in progress) or rinsing (when the rinsing step is in progress), the pump 11 is driven to discharge the washing water in the gap portion 8 into the guide passage 12, and the wash water discharged into the guide passage is It flows to the upper tank 3 along the guide flow path. The wash water is sprayed into the inner tank through the nozzle 13 provided at the end of the guide passage.

그리고, 내조(3)의 탈수공(3b)의 크기 및 개수가 내조 하부로 갈수록 작거나 줄어들기 때문에, 내조 하부로 갈수록 탈수공을 통해 간극부(8)로 유동하는 세탁수량이 줄어들게 된다.In addition, since the size and number of the dehydration holes 3b of the inner tank 3 decrease or decrease as they go toward the lower portion of the inner tank, the amount of washing water flowing to the gap portion 8 through the dehydration hole decreases toward the lower portion of the inner tank.
