본 고안은 드럼세탁기의 세탁수 및 세제절감 장치에 관한 것으로서, 더욱 상세하게는 드럼세탁기의 세탁시 세탁수 및 세제의 사용량을 절감시킴과 동시에 세탁효율을 향상시킬 수 있도록 한 것이다.The present invention relates to a washing machine and a detergent reduction device of a drum washing machine, and more particularly, to reduce the amount of washing water and detergent when washing the drum washing machine and to improve washing efficiency.

종래의 드럼세탁기는 제1도에 나타낸 바와 같이, 본체(6)의 상부일측에 설치된 세제통(8)에 급수밸브(8)를 통해서 물이 투입되면, 세제통(8)내의 세제는 급수된 물과 함께 급수벨로우즈(2a)를 통해서 터브(1a)의 내부로 유입되고, 터브(1a)내에 급수된 물이 수위센서(10)의 감지에 의해 일정수위 이상이 되면, 모터(도시는 생략함)의 구동에 의해 상기 터브(1a)내의 드럼(11)이 좌,우반전을 하게되면, 드럼(11)내의 세탁물은 드럼(11)의 내주면에 설치된 복수개의 리프터(Lifter)(12)에 의해 상부로 들렸다가 세탁수위에 떨어질 때 발생하는 충격 및 굴신작용에 의해 세탁이 진행하게 된다.As shown in FIG. 1, when a conventional drum washing machine is supplied with water through a water supply valve 8 to a detergent container 8 provided on an upper side of the main body 6, the detergent in the detergent container 8 is supplied with the water supplied. When the water supplied into the tub 1a through the water supply bellows 2a and the water supplied in the tub 1a becomes above a certain level by the detection of the water level sensor 10, the motor (not shown) When the drum 11 in the tub 1a is reversed left and right by driving, the laundry in the drum 11 is moved upward by a plurality of lifters 12 installed on the inner circumferential surface of the drum 11. Washing proceeds due to the impact and flexing that occurs when it is dropped into the washing water.

세탁이 완료되면, 터브(1a)하부의 배수벨로우즈(14)에 설치된 배수펌프(13)의 구동에 의해서 배수벨로우즈(14)를 통해 세탁수를 본체(6)의 외부로 내보내고, 다시 급수후 헹굼을 진행하게 되며, 각 헹금중간에도 전술한 과정을 반복하여 헹굼이 끝나면 모터의 고속회전에 의해 탈수시 제거된 세탁수가 본체(6)의 밖으로 배출된다.When washing is completed, the washing water is discharged to the outside of the main body 6 through the drain bellows 14 by driving the drain pump 13 installed in the drain bellows 14 under the tub 1a, and then rinsed after supplying water again. After the rinsing is repeated by repeating the above-described process even during each rinsing, the washing water removed during dehydration by the high speed rotation of the motor is discharged out of the main body 6.

한편, 고온세탁을 할 경우 터브(1a)에 내장된 히터(3)에 의해 가열된 세탁수를 세탁후 즉시 배수하지 않고 급수밸브(9)에서 냉수를 공급받아 물의 온도를 하강시키는 스테이쿨링(Stay Cooling)을 한 다음, 드럼(11)안의 물을 50%정도 1차 배수하게 되는데, 스테이쿨링은 고온 세탁시 세탁후 바로 배수를 하고 급수를 시킬 경우 세탁물에 급격한 온도변화로 인한 손상을 방지하기 위하여 세탁후 배수를 하기전에 냉수를 급수하여 온도를 하강시킨 다음 배수시키는 기능이다.On the other hand, in the case of high-temperature washing, the stapling to lower the temperature of the water by receiving cold water from the water supply valve 9 without immediately draining the wash water heated by the heater 3 built in the tub 1a. After cooling, the water in the drum 11 is first drained by about 50%. In the case of high temperature washing, water is drained immediately after washing and water is supplied to prevent damage due to rapid temperature change in the laundry. After washing, before draining, cold water is supplied to reduce the temperature and then drain.

그러나, 이와 같은 종래의 드럼세탁기는 드럼(11)의 하단부이상으로 급수를 해야 세탁물이 젖게 되므로 세탁수의 사용량이 많아지고, 초기 급수시 세탁수와 함께 유입된 세제가 터브(1a)의 바닥면과 배수 벨로우즈(14)의 내부에 덜 용해된 상태로 침적되어 있으므로 마지막 헹굼시까지 남아있던 일부세제가 세탁성능 및 헹굼비를 저하시키는 원인이 되며, 불완전 용해된 세제가 밖으로 배출되므로 인해 세제의 낭비 및 수질오염을 초래하게 되었다.However, such a conventional drum washing machine requires more water to be supplied to the lower end of the drum 11 so that the laundry becomes wet, so the amount of wash water is increased, and detergent introduced with the wash water at the time of initial water supply is the bottom surface of the tub 1a. Since it is deposited in a less dissolved state inside the drain bellows 14, some detergent remaining until the last rinse may cause deterioration of washing performance and rinsing ratio, and waste of detergent due to incomplete dissolved detergent is discharged out. And water pollution.

뿐만 아니라, 드럼(11)의 회전시 드럼(11)과 세탁수의 접촉에 의해 세탁 중 세제거품이 많이 발생되어 세제거품이 스폰지와 같은 효과를 내므로 세탁물이 드럼(11)내에서 회전하면서 받는 충격력을 감소시켜 세탁효율을 저하시키게 되는 등의 많은 문제점이 있었다.In addition, when the drum 11 is rotated, the detergent is generated during washing due to the contact between the drum 11 and the wash water, and the laundry is rotated in the drum 11 because the detergent is effected as a sponge. There are many problems, such as reducing the impact force to lower the washing efficiency.

본 고안은 상기한 제반 문제점을 해결하기 위한 것으로서, 드럼세탁기의 세탁시 세탁수 및 세제의 사용량을 절감시켜 불완전 용해에 따른 세제의 낭비와 수질오염을 방지할 수 있을 뿐만 아니라, 세제 거품의 발생을 억제하여 세탁효율을 향상시킬 수 있는 드럼세탁기의 세탁수 및 세제 절감장치를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, it is possible to prevent the waste and water pollution of the detergent due to incomplete dissolution by reducing the amount of washing water and detergent when washing the drum washing machine, and to generate the detergent foam It is an object of the present invention to provide a washing machine and a detergent saving device of a drum washing machine that can improve the washing efficiency by suppressing.

상기한 목적을 달성하기 위해 본 고안은 급수 벨로우즈를 통해 초기급수시 유입되는 세탁수와 세제를 절감시키기 위한 세탁수통과 상기 세탁수통을 통해 유입되는 세제의 용해 및 세탁수를 순환시키기 위한 순환호스와, 상기 순환호스에 힌지 결합되어 세탁 및 배수시 선택적으로 순환유로를 폐쇄시키기 위한 첵크밸브로 구성된 드럼세탁기의 세탁수 및 세제절감장치이다.In order to achieve the above object, the present invention provides a washing tub for reducing washing water and detergent introduced during initial water supply through a water supply bellows, and a circulation hose for dissolving detergent and circulating the washing water introduced through the washing tub. It is hinged to the circulation hose, washing water and detergent reduction device of the drum washing machine consisting of a check valve for selectively closing the circulation passage during washing and draining.
