Description

드럼 세탁기의 간헐 탈수 장치 및 제어 방법Intermittent dewatering device and control method of drum washing machine

본 발명은 드럼 세탁기의 간헐 탈수 장치 및 제어 방법에 관한 것으로서, 더욱 상세하게는 드럼 세탁기에서 세탁 행정을 종료하고 헹굼 행정에 들어가기 전에 실행하는 간헐 탈수의 매 행정마다 드럼을 일정한 저속 회전으로 운전하면서 소량의 물을 별도로 구비된 유로를 통해 드럼의 내부에 공급한 후 충분히 물이 공급된 시점에서 간헐 탈수를 행할 수 있도록 한 것이다.The present invention relates to an intermittent dewatering device and a control method of a drum washing machine, and more particularly, a small amount while driving the drum at a constant low-speed rotation every stroke of the intermittent dewatering performed in the drum washing machine before ending the washing stroke and entering the rinsing stroke. After supplying the water to the inside of the drum through a separately provided flow path is to be able to perform intermittent dehydration at a time when enough water is supplied.

종래의 드럼 세탁기는 제1도에 나타낸 바와 같이, 본체(1)내의 터브(2) 내부에 드럼(7)이 회전 가능하게 설치되고, 상기 터브(2)의 상, 하부는 스프링(15)과 진동 방지구(16)에 의해 본체(1)의 내부에 지지되며, 상기 드럼(7)의 일단에는 동력을 전달하기 위한 풀리(17)가 설치된다.In the conventional drum washing machine, as shown in FIG. 1, the drum 7 is rotatably installed in the tub 2 in the main body 1, and the upper and lower parts of the tub 2 are springs 15 and the lower part. It is supported inside the main body 1 by the anti-vibration port 16, and one end of the drum 7 is provided with a pulley 17 for transmitting power.

또한, 본체(1)내의 상단 일측에는 세제통(12)이 설치되고, 세제통(12)과 터브(2) 상부의 사이에는 상기 본체(1) 상의 수도 밸브(9)와 외부 급수호스(10) 및 본체(1) 내의 급수 밸브(5)와 내부 급수호스(11)를 거쳐 세제통(12)으로 유입된 물을 드럼(7)에 형성된 복수개의 통공(14)을 통해 공급하기 위한 급수관(13)이 설치되며, 터브(2) 전방의 중앙부와 본체(1)의 내부 사이에는 벨로우즈(3a)가 설치되고, 상기 본체(1) 전방의 중앙부에는 드럼(7) 내의 세탁물의 상태를 육안으로 볼 수 있는 투명창(4)이 부착되어 구성된다.In addition, a detergent container 12 is installed at one side of the upper end of the main body 1, and the water valve 9 and the external water supply hose 10 on the main body 1 are disposed between the detergent container 12 and the tub 2. A water supply pipe 13 for supplying water introduced into the detergent container 12 through the water supply valve 5 and the internal water supply hose 11 in the main body 1 through the plurality of through holes 14 formed in the drum 7 is provided. And a bellows 3a is installed between the central part in front of the tub 2 and the inside of the main body 1, and the state of the laundry in the drum 7 can be visually seen in the central part in front of the main body 1. The transparent window 4 is attached and comprised.

따라서, 드럼 세탁기의 드럼(7) 내부에 세탁물을 넣고 세탁을 하게 되면 제2도에 나타낸 바와 같이 물이 본체(1)상의 수도 밸브(9)를 통해 외부 급수호스(10) 및 본체(1)내의 급수 밸브(5)와 내부 급수호스(11) 및 세제통(12)을 거쳐서 급수관(13)을 통해 드럼(7)에 형성된 복수개의 통공(14)으로 급수가 되어 세탁 행정을 진행하게 되고, 세탁 행정이 완료되면 오염된 물을 배수하게 되며, 헹굼 행정에 들어가기 전에 일정 속도의 간헐 탈수를 하므로써 세탁물에 잔류된 물이 원심력에 의해서 드럼(7)의 통공(14)을 통해 외부로 빠져나가면서 세제와 오염물을 함께 이동시켜 분리한다.Therefore, when the laundry is put into the drum 7 of the drum washing machine and washed, water is supplied to the external water supply hose 10 and the main body 1 through the water valve 9 on the main body 1 as shown in FIG. Water is supplied to the plurality of through holes 14 formed in the drum 7 through the water supply pipe 13 through the water supply valve 5, the internal water supply hose 11, and the detergent container 12, and the washing process proceeds. When the stroke is completed, the contaminated water is drained, and the water remaining in the laundry is discharged to the outside through the through hole 14 of the drum 7 by centrifugal force by intermittent dehydration at a constant speed before entering the rinse stroke. And contaminants are separated together by moving them together.

그 후, 이 과정을 거친 다음 헹굼 행정을 실행하고, 배수와 탈수 행정을 한 후 세탁물의 전체 세탁 행정을 종료하게 된다.Thereafter, after this process, the rinsing stroke is executed, the draining and dehydrating stroke is performed, and the entire washing stroke of the laundry is finished.

그러나, 이와 같은 종래의 드럼 세탁기는 세탁물의 헹굼 행정을 진행하기 전에 물의 추가 공급 없이 세탁물에 잔류되어 있는 물만으로 고속의 간헐 탈수를 진행하므로 인해 세탁물 중심부의 물이 원심력에 의해서 드럼(7)의 외부로 이동하면서 잔류 세제와 오염물들을 분리하지만, 잔류된 물의 양이 적어 간헐 탈수 초기에 대부분의 물이 빠져서 나가버려 헹굼 효율이 많이 떨어지게 되었다.However, such a conventional drum washing machine performs high-speed intermittent dehydration only with the water remaining in the laundry without additional supply of water before proceeding with the rinsing process of the laundry. Residual detergent and contaminants were separated while moving to, but the amount of residual water was low, which caused most of the water to drain out at the beginning of intermittent dehydration, resulting in a poor rinsing efficiency.

뿐만 아니라, 헹굼을 하더라도 물 속에 포함된 미량의 세제 성분이 거품을 발생해서 투명창(4)의 주위에 달라붙게 되므로 인해 세탁물의 전체 세탁 행정이 종료된 후에도 육안으로 보이는 경우가 있어서 세탁물의 청결감을 떨어뜨리게 되는 등의 많은 문제점이 있었다.In addition, even when rinsing, a small amount of detergent contained in the water generates bubbles and clings around the transparent window 4, so that it may be visible to the naked eye even after the entire washing process of the laundry is finished. There were many problems such as being dropped.

본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 드럼 세탁기에서 세탁 행정을 종료하고 헹굼 행정에 들어가기 전에 실행하는 간헐 탈수의 매 행정마다 드럼을 일정한 저속 회전으로 운전하면서 소량의 물을 별도로 구비된 유로를 통해 드럼의 내부에 공급한 후 충분히 물이 공급된 시점에서 간헐 탈수를 행할 수 있도록 하여 세탁물의 헹굼 성능을 향상시킬 수 있을 뿐만 아니라 세탁수와 사용 전력의 소비량을 절감시킬 수 있는 드럼 세탁기의 간헐 탈수 장치 및 제어 방법을 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the flow path is provided with a small amount of water separately while driving the drum at a constant low speed rotation in every stroke of intermittent dehydration performed before the washing stroke is finished in the drum washing machine and before entering the rinsing stroke.

After rinsing, a spray nozzle 8 for intermediately supplying a small amount of water to the inside of the drum 7 is disposed so as to face a small amount of detergent bubbles attached to the periphery of the transparent window 4.

이와 같이 구성된 본 발명은 제3도 내지 제5도에 나타낸 바와 같이, 드럼 세탁기의 본체(1) 내부와 터브(2) 전방의 중앙부 사이에 설치된 벨로우즈(3)내의 투명창(4)상부 경사면에 금수 밸브(5)와 호스(6)로서 연결되어 분사 노즐(8)이 대향되도록 설치된 상태에서 세탁물의 세탁시에는 상기 터브(2)의 내부에 회전 가능하게 설치된 드럼(7)의 내부에 세탁물을 넣은 후 물을 본체(1)상의 수도 밸브(9)를 통해 외부 급수호스(10) 및 본체(1)내의 급수 밸브(5)와 내부 급수호스(11) 및 세제통(12)을 거쳐서 급수관(13)을 통해 드럼(7)에 형성된 복수개의 통공(14)으로 급수하여 세탁 행정을 진행하게 된다.As shown in FIGS. 3 to 5, the present invention configured as described above is provided on the inclined surface of the upper portion of the transparent window 4 in the bellows 3 provided between the inside of the main body 1 of the drum washing machine and the center of the front of the tub 2. When washing the laundry in a state in which the spray nozzle 8 is connected to the water valve 5 and the hose 6 so as to face each other, the laundry is placed inside the drum 7 rotatably installed in the tub 2. After the water is supplied, the water supply pipe (13) through the water supply valve (9) on the main body (1) through the external water supply hose (10) and the water supply valve (5) in the main body (1), the internal water supply hose (11) and the detergent container (12). Water is supplied to the plurality of through holes 14 formed in the drum 7 to proceed the washing process.

그 후, 세탁 행정이 완료되면 배수 행정을 진행한 다음 t1~t2시간 동안 제5도의 탈수 속도 n1인 100rpm이하의 속도로 드럼(7)을 회전시키면서 급수 밸브(5)를 열어 분사 노즐(8)을 통해 투명창(4)의 상부 경사면에 소량의 물을 상기 드럼(7)의 내부로 공급하는 중간 급수1을 행한다.Then, when the washing stroke is completed, proceed with the drainage stroke and then open the water supply valve 5 while rotating the drum 7 at a speed of 100 rpm or less, which is the dehydration speed n1 of FIG. 5 for t1 to t2 hours, and then the injection nozzle 8 The intermediate water supply 1 for supplying a small amount of water to the inside of the drum 7 through the upper inclined surface of the transparent window 4 is performed.

그 후, 드럼(7)내의 세탁물이 충분히 적셔진 다음 급수를 중단하고, t3~t4시간 동안 탈수 속도 n2의 간헐 탈수를 실행한다.Thereafter, after the laundry in the drum 7 is sufficiently wetted, the water supply is stopped, and intermittent dehydration at a dehydration rate n2 is performed for t3 to t4 hours.

이때, 세탁물 내에 함유된 물은 원심력에 의해 드럼(7)의 외부로 이동하면서 잔류 세제와 오염물을 배출시키게 되는데, 이 과정으로 세탁물은 상당히 깨끗해져서 짧은 헹굼 행정으로도 충분한 헹굼 성능을 발휘하여 세탁수와 사용 소비전력을 크게 절감할 수 있게 된다.At this time, the water contained in the laundry moves to the outside of the drum 7 by centrifugal force to discharge residual detergent and contaminants. In this process, the laundry is considerably clean, so that even the short rinsing stroke provides sufficient rinsing performance. And the power consumption can be greatly reduced.

그 다음, 헹굼 행정이 종료되면 배수를 실행하고, t5~t6시간 동안 탈수 속도로 탈수를 행하여 탈수 행정을 종료하며, 헹굼을 하더라도 잔류된 미량의 세제 성분이 거품을 발생하여 투명창(4)의 주변에 부착하게 되는데, 이때 분사 노즐(8)을 통해서 투명창(4)으로 중간 급수2를 통하여 투명창(4)에 부착된 거품을 깨끗이 세척하여 사용자에게 청결함을 줄 수 있게 된다.Then, when the rinse cycle is finished, drainage is performed, and the dehydration stroke is terminated by dehydration at a dehydration speed for t5 to t6 hours, and even when rinsing, a small amount of the detergent component remaining generates bubbles to form the transparent window 4. It is attached to the periphery, in which the foam attached to the transparent window (4) through the intermediate water supply 2 to the transparent window (4) through the spray nozzle (8) to clean the user can be provided.

이상에서와 같이, 본 발명은 전자동 세탁기에서 헹굼 행정 직전의 간헐 탈수의 매 행정마다 드럼(7)을 일정한 저속 회전으로 운전하면서 소량의 물을 별도로 구비된 유로를 통해 드럼(7)의 내부에 공급하다가 충분히 물이 공급된 시점에서 간헐 탈수를 행하므로써 세탁기의 운전 시간을 단축시킬 수 있고, 헹굼 효과가 뛰어난 세탁수 및 사용 전력의 소비량을 감소시킬 수 있으며, 헹굼 종료 후에도 급수를 투명창(4)의 상부면에 분사하여 헹굼시 발생한 거품을 제거할 수 있어서 청결함을 제공할 수 있는 등의 많은 장점이 구비된 매우 유용한 발명이다.As described above, the present invention supplies a small amount of water to the inside of the drum 7 through a separately provided flow path while driving the drum 7 at a constant low-speed rotation in every stroke of intermittent dehydration just before the rinsing stroke in the automatic washing machine.
