Description

세탁기의 절수장치{Water saving of washing machine}Water saving of washing machine

본 발명은 세탁기의 절수장치에 관한 것으로, 더욱 상세하게는 세탁수 급수량을 줄이면서도 세탁 및 헹굼행정을 원활하게 수행할 수 있도록 하는 세탁기의 절수장치에 관한 것이다.The present invention relates to a water-saving device of a washing machine, and more particularly, to a water-saving device of a washing machine that can smoothly perform washing and rinsing administration while reducing the amount of washing water supplied.

일반적으로 세탁기는 세탁, 헹굼 그리고 배수 및 탈수행정 등이 콘트롤부의 마이콤에 미리 프로그램화되어 있고, 사용자가 이를 선택적으로 제어할 수 있도록 구성되어 있어서, 프로그램화된 일련의 과정을 거쳐 세탁물이 전자동으로 세탁된다.In general, a washing machine is pre-programmed with washing, rinsing, drainage, and dehydration strokes in the microcomputer of the control unit, and is configured to allow the user to selectively control the washing machine. do.

이러한 기능을 하는 세탁기는 도 1에 도시한 바와 같이, 외관을 이루는 하우징(1) 내부에 세탁에 필요한 일정량의 세탁수를 담수하는 수조(2), 수조(2) 내부에 회전가능하게 장착되며 벽면에 탈수공(3a)이 천공된 원통상의 탈수조(3), 탈수조(3) 저부에 정역회전 가능하게 설치된 펄세이터(4) 등으로 크게 구성되어 있다.The washing machine having such a function is rotatably mounted in the water tank 2 and the water tank 2 to receive a certain amount of washing water required for washing in the housing 1 forming the exterior, as shown in FIG. It consists of the cylindrical dewatering tank 3 with which the dehydration hole 3a was perforated, and the pulsator 4 etc. which were installed in the bottom of the dehydrating tank 3 so that reverse rotation was possible.

수조(2)는 세탁기의 구동시 발생되는 진동이 완화되도록 현가장치(5)를 통해 하우징(1) 내부에 매달려 설치된다. 수조(2)의 외측 하부에는 탈수조(3)와 펄세이터(4)를 구동시키기 위한 구동부(6)가 장착되는데, 이것은 회전력을 발생시키는 모터(6a), 벨트(6d)를 매개로하여 모터(6a)의 회전력을 전달받고 회전축(6c)을 통해 펄세이터(4)와 탈수조(3)를 구동시키는 클러치(6b) 등으로 구성되어 있다.The water tank 2 is installed to hang inside the housing 1 through the suspension device 5 so as to alleviate the vibration generated when the washing machine is driven. The lower part of the outer tank 2 is equipped with a drive unit 6 for driving the dehydration tank 3 and the pulsator 4, which are driven by a motor 6a and a belt 6d that generate rotational force. It consists of a clutch 6b etc. which receive the rotational force of 6a and drive the pulsator 4 and the dehydration tank 3 via the rotation shaft 6c.

즉, 세탁 및 헹굼행정시에는 클러치(6b)에 의해 동력이 펄세이터(4)만으로 전달되고, 탈수행정시에는 동력이 펄세이터(4)와 탈수조(3)가 동시 회전되도록 전달된다. 미설명부호 7은 세탁수를 외부로 배출하기 위한 배수호스로서, 하우징(1) 외부까지 연장되게 마련된다.That is, the power is transmitted to the pulsator 4 only by the clutch 6b during washing and rinsing stroke, and the power is transmitted such that the pulsator 4 and the dehydrating tank 3 rotate at the same time during the dehydration stroke. Reference numeral 7 is a drain hose for discharging the washing water to the outside, it is provided to extend to the outside of the housing (1).

그리고 탈수조(3)는 탈수공(3a)이 벽면 전역에 걸쳐 균일하게 천공되어 있으며, 다수의 날개가 방사상으로 형성된 펄세이터(4)는 이러한 탈수조(3)의 내측 저부에 정역회전가능하게 설치됨으로써, 세탁 및 헹굼행정시 세탁수류를 형성한다.In the dehydration tank 3, the dehydration hole 3a is uniformly perforated over the entire wall surface, and the pulsator 4, in which a plurality of wings are radially formed, is capable of forward and reverse rotation at the inner bottom of the dehydration tank 3. By being installed, the washing water flow is formed during washing and rinsing.

이와 같이 구성된 종래 세탁기는 미리 프로그램화 된 콘트롤부(미도시)의 명령에 따라 세탁과 배수 및 탈수행정을 수행하게 된다. 즉, 탈수조(3)에 세탁물을 투입한 후 사용자가 콘트롤부(미도시)를 통해 세탁기를 작동시키면, 세탁수와 세제가 탈수조(3) 내로 공급된다. 이 때, 탈수조(3) 내로 급수되는 세탁수는 다수의 탈수공(3a)을 통해 빠져나가면서 수조(2) 내부에 담수 저장된다.The conventional washing machine configured as described above performs washing, draining, and dehydrating operations according to a command of a preprogrammed control unit (not shown). That is, after the laundry is put into the dehydration tank 3 and the user operates the washing machine through a control unit (not shown), the washing water and the detergent are supplied into the dehydration tank 3. At this time, the wash water supplied into the dehydration tank (3) is stored in the fresh water tank (2) while leaving the plurality of dehydration holes (3a).

수조(2)에 적당량의 세탁수가 담수되면, 모터(6a)에 전원이 인가되어 동력이 발생되고 이의 동력을 전달받아 펄세이터(4)가 정역회전함으로써, 탈수조(3) 내에 세탁수류가 형성 세탁 및 헹굼행정이 수행된다.When a suitable amount of washing water is fresh in the water tank 2, power is applied to the motor 6a to generate power, and the power is transmitted to the pulsator 4 so that the water flows forward and backward, thereby forming a water flow in the dewatering tank 3. Washing and rinsing strokes are performed.

이러한 행정이 완료된 후에는 수조(2)에 담수된 세탁수는 배수호스(7)를 통해 하우징(1) 외부로 배출된다. 그리고 탈수조(3)와 펄세이터(4)가 일방향으로 고속회전함으로써, 탈수행정이 수행된다.After this stroke is completed, the fresh water washed in the water tank 2 is discharged to the outside of the housing 1 through the drain hose 7. And the dehydration tank 3 and the pulsator 4 are rotated at high speed in one direction, so that the dehydration stroke is performed.

그러나 이러한 종래 세탁기는 모든 세탁과 헹굼행정이 세탁물이 담겨지는 탈수조(3) 내부에서만 이루어지는데도 불구하고 수조(2)와 탈수조(3) 사이의 공간에까지 세탁수가 공급된 상태로 세탁 및 헹굼행정이 수행됨으로써, 물 사용량이 많아지게 된다.However, in the conventional washing machine, although all washing and rinsing operations are performed only in the dehydration tank 3 in which the laundry is contained, the washing and rinsing administration with the washing water supplied to the space between the water tank 2 and the dehydration tank 3 is carried out. By this, the amount of water used is increased.

즉, 종래에는 도 1에 도시한 바와 같이 탈수공(3a)이 탈수조(3)의 벽면 전역에 걸쳐 천공되어 있기 때문에, 세탁수는 다수의 탈수공(3a)을 통해 탈수조(3)와 수조(2) 내를 자유롭게 출입하여 탈수조(3)와 수조(2)의 수위가 거의 동일한 상태를 유지하면서 세탁 및 헹굼행정이 수행된다. 이에 따라 실제 세탁이 수행되지 않는 수조(2)에까지 탈수조(3)와 동일높이의 세탁수가 담수됨으로써, 물 사용량이 많아지는 것은 물론이며 물과 함께 공급되는 세제량도 많아지게 된다. 또한, 이러한 많은 양의 세탁수 배출로 인해 최근 거론되고 있는 수질오염이 가중되는 문제점이 있다.That is, since the dehydration hole (3a) is conventionally drilled over the entire wall surface of the dehydration tank (3), as shown in Fig. 1, the wash water and the dehydration tank (3) through a plurality of dehydration holes (3a) The inside of the water tank 2 is freely moved in and out, while washing and rinsing administration are performed while maintaining the same level of water in the dewatering tank 3 and the water tank 2. Accordingly, by washing the washing water at the same height as the dehydration tank 3 to the tank 2 in which the actual washing is not performed, the amount of water used is increased and the amount of detergent supplied with the water is also increased. In addition, there is a problem that water pollution, which has been recently discussed, is aggravated by such a large amount of washing water discharge.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 원통형상의 탈수조 상단에 탈수공을 국부적으로 천공하고 세탁 및 헹굼행정시 실제 세탁물이 담겨지는 탈수조 수위보다 수조 수위를 낮게 유지시킴으로써, 세탁수와 세제 사용량을 최대한 절감할 수 있게 하는 세탁기의 절수장치를 제공하는 것이다.The present invention is to solve this problem, an object of the present invention by locally drilling the dehydration hole on the top of the cylindrical dehydration tank and by maintaining the water tank level lower than the dehydration tank level in which the actual laundry is contained during washing and rinsing administration, It is to provide a water-saving device of the washing machine to reduce the amount of washing water and detergent as much as possible.

And a buoyancy member provided to be elevated to open and close the drainage hole according to the excess buoyancy.

이하, 본 발명에 따른 하나의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다. 도 2와 도 3은 본 발명이 적용된 세탁기의 전체적인 내부구조와 탈수조 및 부력부재를 보인 것이고, 도 4내지 도 6은 본 발명이 적용된 세탁기의 작동상태를 보인 것이다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. 2 and 3 show the overall internal structure of the washing machine to which the present invention is applied and the dehydration tank and the buoyancy member, and FIGS. 4 to 6 show the operating state of the washing machine to which the present invention is applied.

본 발명에 따른 세탁기는 도 2에 도시한 바와 같이, 외형 몸체를 이루는 하우징(10) 내부에 현가 설치되는 수조(20), 세탁수류를 형성하는 펄세이터(34)가 내장된 탈수조(30)와 이를 구동시키기 위한 구동부(40) 등으로 크게 구성되어 있다.As shown in FIG. 2, the washing machine according to the present invention includes a water tank 20 in which a suspension is installed in a housing 10 constituting an outer body, and a dehydration tank 30 in which a pulsator 34 forming a washing water flow is built. And a driving part 40 for driving the same.

플라스틱재로 사출성형되는 하우징(10)은 상부가 개방된 사각통상으로 이루어지며, 이의 상부에 세탁물을 투입, 인출하기 위한 뚜껑(12)과 세제용해장치(13)가 마련된 상부커버(11)가 결합된다. 수조(20)는 상부가 개방된 플라스틱 원통상으로 구성되어 있으며, 지지봉(141)과 완충스프링 등으로 이루어진 4개의 현가장치(14)를 통해 하우징(10) 내부공간에 매달려 설치된다. 즉, 지지봉(141)의 일단부는 하우징(10)의 상측단부에 고정되고, 이의 타단부는 수조(20) 하측에 고정되며 완충스프링이 내장된 케이스(142) 내부에 결합된다. 따라서 완충스프링의 탄성복원력에 의해 세탁기의 작동시 발생된 진동과 충격이 완화된다.The housing 10 which is injection-molded with a plastic material is formed in a rectangular cylinder with an open top, and a lid 12 and a top cover 11 having a lid 12 and a detergent dissolving device 13 for inputting and withdrawing laundry thereon are provided. Combined. The water tank 20 is composed of a plastic cylinder with an open top, and is suspended from the inner space of the housing 10 through four suspension devices 14 including a support rod 141 and a buffer spring. That is, one end of the support rod 141 is fixed to the upper end of the housing 10, the other end thereof is fixed to the lower side of the water tank 20 and is coupled to the case 142 in which the shock absorbing spring is built. Therefore, the vibration and shock generated during operation of the washing machine by the elastic restoring force of the shock absorbing spring is alleviated.

구동부(40)는 모터(41)와 클러치(42) 등으로 크게 구성되어 있는데, 이들은 완충지지된 수조(20)의 하면에 장착된다. 동력을 탈수조(30)와 펄세이터(34)로 구분 전달하는 클러치(42)는 수조(20)의 하측 중심부에 고정되며, 이의 회전축(43) 단부가 탈수조(30) 및 펄세이터(34) 중심부와 결합되어 있다. 이에 따라 클러치(42)에 의해 세탁 및 헹굼행정시에는 펄세이터(34)만 정역회전되고, 탈수행정시에는 펄세이터(34)와 탈수조(30)가 일방향으로 동시 회전된다. 그리고 모터(41)는 동력을 발생하여 클러치(42)로 전달하는데, 이를 위해 모터(41)의 풀리(411)와 클러치(42)의 풀리(421)는 벨트(44)를 매개로 연결되어 있다.The drive unit 40 is largely composed of a motor 41, a clutch 42, and the like, which are mounted on the bottom surface of the buffer tank 20 that is buffered and supported. Clutch 42 for transmitting power to the dehydration tank 30 and the pulsator 34 is fixed to the lower center of the water tank 20, the end of the rotary shaft 43 of the dehydration tank 30 and the pulsator 34 ) Is combined with the center. Accordingly, only the pulsator 34 is rotated forward and backward during washing and rinsing stroke by the clutch 42, and the pulsator 34 and the dewatering tank 30 are simultaneously rotated in one direction during the dehydration stroke. The motor 41 generates power and transmits the power to the clutch 42. To this end, the pulley 411 of the motor 41 and the pulley 421 of the clutch 42 are connected to each other via a belt 44. .

탈수조(30)는 수조(20) 내부에서 회전가능하도록 이의 내벽과 일정한 간격을 유지하도록 설치되는데, 이것은 도 3에 도시한 바와 같이, 상하부가 개방된 원통형상의 원통몸체(31)와 접시모양의 하부몸체(32)로 구성되어 있다. 그리고 이러한 탈수조(30)의 하부몸체(32) 상부에 펄세이터(34,도 2참조)가 설치된다.The dehydration tank 30 is installed to maintain a constant distance from the inner wall thereof so as to be rotatable inside the water tank 20, which is, as shown in Figure 3, the cylindrical body 31 and the plate-shaped cylindrical body of the upper and lower portions are opened. It is composed of a lower body (32). And the pulsator 34 (see Fig. 2) is installed on the lower body 32 of the dehydration tank (30).

펄세이터(34)는 클러치(42)의 회전축(43)과 결합되어 세탁행정시 정역회전함으로써 세탁수류를 형성하는데, 이것은 원판상으로 마련된 몸체(341) 상면에 상측으로 돌출된 세탁봉(343)과 방사상의 세탁날개(342)로 구성되어 있다.The pulsator 34 is combined with the rotating shaft 43 of the clutch 42 to form a washing water flow by forward and reverse rotation during the washing stroke, which is a washing rod 343 protruding upward on the upper surface of the body 341 provided in a disc shape. And radial washing blades 342.

그리고 탈수조(30)의 원통몸체(31)는 스테인레스재질로 구성되며, 이의 최상단 내측에는 염수가 채워진 밸런서(37)가 원주방향으로 장착된다. 밸런서(37)는 염수의 파동을 통해 세탁 및 헹굼행정시 발생되는 진동을 소멸시키고, 탈수행정시 탈수조(30)의 균형을 유지하는 기능을 수행한다. 이러한 원통몸체(31)에는 세탁수를 절수하기 위해 탈수공(311)이 상단부에만 국부적으로 천공되어 있다. 즉, 탈수공(311)은 밸런서(37) 하단과 인접하는 원통몸체(31) 상단부를 따라 원주방향으로 형성되며, 이웃하는 것들과 일정간격 이격되게 일렬로 천공된다.And the cylindrical body 31 of the dehydration tank 30 is made of a stainless material, the top of the inner end of the balancer 37 filled with saline is mounted in the circumferential direction. The balancer 37 eliminates vibration generated during washing and rinsing strokes through a wave of brine, and maintains a balance of the dehydrating tank 30 during the dehydrating stroke. In the cylindrical body 31, the dewatering hole 311 is locally drilled only at the upper end to save the wash water. That is, the dehydration hole 311 is formed in the circumferential direction along the upper end of the cylindrical body 31 adjacent to the lower end of the balancer 37, and is drilled in a line at a predetermined interval from the neighboring ones.

한편, 접시모양의 하부몸체(32)는 외측면부가 원통몸체(31)의 하측단부에 스크류(33)결합되며 이의 중심부에 클러치(42)의 회전축(43)이 결합되는데, 회전축(43) 결합을 위해 하부몸체(32) 하면에는 원판상으로 이루어진 샤프트플랜지(36)가 스크류(35)결합되어 있다. 샤프트플랜지(36)는 정중앙부에 클러치(42)의 회전축(43)이 관통하여 결합되도록 결합공(362,도 3참조)이 천공되어 있으며, 결합공(362) 인접부위에는 다수개의 배수홀(361)이 중심에 대해 대칭되게 형성되어 있다. 이러한 배수홀(361)을 통해 탈수조(30)와 수조(20)가 연통되기 때문에, 배수행정시 탈수조(30) 내의 세탁수가 수조(20) 측으로 배수된다.On the other hand, the lower body 32 of the plate-like outer side portion screw 33 is coupled to the lower end of the cylindrical body 31 and the rotary shaft 43 of the clutch 42 is coupled to the center thereof, the rotary shaft 43 is coupled For the lower body 32, the shaft flange 36 made of a disc shape is coupled to the screw (35). The shaft flange 36 has a coupling hole 362 (see FIG. 3) so that the rotation shaft 43 of the clutch 42 penetrates in the center portion thereof, and a plurality of drainage holes are formed in an adjacent portion of the coupling hole 362. 361 is formed symmetrically about the center. Since the dehydration tank 30 and the water tank 20 communicate with each other through the drain hole 361, the washing water in the dewatering tank 30 is drained to the water tank 20 side during the drainage stroke.

또한, 세탁 및 헹굼행정시 절수를 위해서 탈수조(30) 저면 이상으로 물이 급수되면 탈수조(30) 수위가 수조(20)보다 높게 유지되도록 부력에 의해 승강하여 배수홀(361)을 폐쇄하는 부력부재(38)가 탈수조(30) 저면과 수조(20) 사이에 설치되어 있다.In addition, when water is supplied over the bottom of the dehydration tank 30 for water saving during washing and rinsing administration, the dehydration tank 30 is elevated by buoyancy to maintain the water level higher than the water tank 20 to close the drainage hole 361. The buoyancy member 38 is provided between the bottom surface of the dehydration tank 30 and the water tank 20.

부력부재(38)는 도 3에 도시한 바와 같이, 직경(D1)이 배수홀(361)의 최장거리(D2)보다 크게 이루어진 도넛(doughnut) 형상으로 구성되어 있으며, 이의 중심부에는 클러치(42)의 회전축(43)부분이 여유있게 관통하도록 관통구(384)가 형성된다. 부력부재(38) 내부는 이의 부상력을 크게 하기 위해 외부와 차단된 공기실(382)이 형성되어 있으며, 구획벽(383)에 의해 다수개로 구획되어 있다.As shown in FIG. 3, the buoyancy member 38 has a donut shape having a diameter D1 larger than the longest distance D2 of the drainage hole 361, and a clutch 42 at the center thereof. The through hole 384 is formed so that the portion of the rotating shaft 43 passes through. Inside the buoyancy member 38 is formed an air chamber 382, which is blocked from the outside to increase its floating force, and is divided into a plurality of partition walls 383.

그리고 부력부재(38)의 상면은 평면상으로 이루어진 씰링면(381)으로 구성된다. 이것은 부력에 의해 부력부재(38)가 승강하면 씰링면(381)을 통해 평면상으로 구성된 탈수조(30) 저부의 샤프트플랜지(36) 하면과 밀착시켜 배수홀(361)을 폐쇄하기 위함이다. 또한, 씰링면(381)의 상면에는 이의 밀착력을 크게 하기 위해 탄성재질, 즉 고무판상으로 이루어진 패킹(385)이 부착되어 있다.And the upper surface of the buoyancy member 38 is composed of a sealing surface 381 made of a plane. This is to close the drain hole 361 in close contact with the bottom surface of the shaft flange 36 of the bottom of the dehydration tank 30 formed in a plane through the sealing surface 381 when the buoyancy member 38 is lifted by the buoyancy. In addition, a packing 385 made of an elastic material, that is, a rubber plate is attached to the upper surface of the sealing surface 381 in order to increase its adhesion.

즉, 회전축(43)이 관통구(384)를 관통하도록 도넛형상의 부력부재(38)를 탈수조(30) 저면과 수조(20) 사이에 설치하면, 회전축(43)이 여유있게 관통하기 때문에 부력부재(38)는 외부의 구속력이 미치지 않게 된다.That is, when the donut-shaped buoyancy member 38 is installed between the bottom surface of the dehydration tank 30 and the water tank 20 so that the rotation shaft 43 penetrates the through hole 384, the rotation shaft 43 can penetrate with ease. The buoyancy member 38 is not affected by the external constraint.

이러한 상태에서 세탁수가 급수되어 배수홀(361)을 통해 수조(20) 내측으로 유입되면, 부력부재(38)는 부력에 의해 떠올라 배수홀(361)을 막게 된다. 이러한 것은 작동설명에서 상세하게 설명한다.In this state, when the wash water is supplied to the water tank 20 through the drainage hole 361, the buoyancy member 38 floats due to the buoyancy to block the drainage hole 361. This is described in detail in the operation description.

미설명부호 50은 수조(20)의 하부에서부터 하우징(10) 외부까지 연장되게 배설된 배수호스이며, 여기에는 이를 선택적으로 개폐하기 위한 배수밸브(51)가 마련되어 있다.Reference numeral 50 is a drain hose disposed to extend from the lower part of the water tank 20 to the outside of the housing 10, and a drain valve 51 for selectively opening and closing the drainage hose 51 is provided.

다음에는 이와 같이 구성된 본 발명에 따른 세탁기의 작동을 설명한다.Next will be described the operation of the washing machine according to the present invention configured as described above.

먼저, 뚜껑(12)을 열고 탈수조(30)에 세탁물을 투입한 후 콘트롤부(미도시)를 통해 세탁기를 작동시키면, 세탁물 양에 따라 세제용해장치(13)에 담겨진 세제와 함게 적당량의 세탁수가 탈수조(30) 내로 급수된다.First, after opening the lid 12 and putting the laundry in the dehydration tank 30 and operating the washing machine through a control unit (not shown), according to the amount of laundry washing with an appropriate amount of detergent with the detergent contained in the detergent dissolving device (13) The water is fed into the dehydration tank 30.

급수되는 세탁수는 배수홀(361)을 통해 탈수조(30) 외부로 일부 빠져나가 수조(20) 내부에도 채워져 부력부재(38)가 점차 떠오르게 되는데, 도 4에 도시한 바와 같이, 탈수조(30) 저면 이상으로 급수되면 부력부재(38)가 완전히 잠기게 된다. 이에 따라 부력부재(38)는 부력에 의해 떠올라 씰링면(381)이 샤프트플랜지(36)의 하면에 밀착되어 배수홀(361)이 폐쇄됨으로써, 그 이상 급수되는 세탁수는 탈수조(30)에만 담수되어 탈수조(30) 수위가 수조(20)보다 높게 된다.The wash water being supplied is partially drained out of the dehydration tank 30 through the drainage hole 361 and filled in the water tank 20 so that the buoyancy member 38 gradually rises, as shown in FIG. 4. 30) When the water is supplied above the bottom surface, the buoyancy member 38 is completely locked. Accordingly, the buoyancy member 38 floats due to the buoyancy, and the sealing surface 381 is in close contact with the lower surface of the shaft flange 36 so that the drainage hole 361 is closed. The fresh water is dewatering tank 30 is higher than the water tank 20.

세탁수 급수가 계속 진행되어 탈수조(30) 내의 물 자중에 의해 부력부재(38)에 하방으로 작용하는 힘이 부력부재(38)의 부력보다 크게 되면, 부력부재(38)는 샤프트플랜지(36)로부터 하측방향으로 이격되어 다시 탈수조(30) 내의 세탁수는 배수홀(361)을 통해 수조(20) 내측으로 유입된다.When the washing water is continuously supplied and the force acting downward to the buoyancy member 38 by the water weight in the dewatering tank 30 is greater than the buoyancy of the buoyancy member 38, the buoyancy member 38 is the shaft flange 36. The washing water in the dehydration tank 30 again flows downward from the bottom) and flows into the water tank 20 through the drain hole 361.

계속하여, 수조(20) 내측으로 세탁수가 유입됨에 따라 부력부재(38)의 부력이 탈수조(30) 내의 물 자중에 의해 부력부재(38)에 하방으로 작용하는 힘보다 크게 되면, 부력부재(38)가 다시 승강하여 배수홀(361)을 폐쇄함으로써, 도 5에 도시한 바와 같이 최종적으로 세탁수 급수가 완료되면 탈수조(30) 수위가 수조(20)보다 "h"만큼 높게 유지된다. 이에 따라 수조(20)에 수위차 "h" 만큼의 불필요한 세탁수 급수가 방지되어 물 사용량이 절감된다.Subsequently, if the buoyancy of the buoyancy member 38 is greater than the force acting downward on the buoyancy member 38 by the water weight in the dewatering tank 30 as the wash water flows into the water tank 20, the buoyancy member ( 38 is lifted again to close the drainage hole 361, and as shown in FIG. 5, when the water supply for washing water is finally completed, the water level of the dehydration tank 30 is maintained higher by "h" than the water tank 20. Accordingly, unnecessary water supply to the water tank 20 is prevented as much as the water level difference "h", thereby reducing the amount of water used.

이러한 상태에서 모터(41)에 전원이 인가되면 동력이 발생되고, 클러치(42)는 회전축(43)을 매개로하여 펄세이터(34)를 정역회전시킨다. 이에 따라 세탁날개(342)에 의해 세탁수류가 발생되어 세탁물은 탈수조(30) 내벽 등과 지속적으로 마찰하면서 세탁이 수행된다. 이 때, 세탁수는 세탁물이 실제로 담겨지는 탈수조(30)에만 충분한 양이 공급된 상태에서 세탁 및 헹굼행정이 수행되기 때문에, 세탁수는 물론이고, 세제 사용량이 월등하게 절감된다.When power is applied to the motor 41 in this state, power is generated, and the clutch 42 rotates the pulsator 34 forward and backward through the rotation shaft 43. Accordingly, the washing water flow is generated by the washing blade 342 so that the laundry is continuously rubbed with the inner wall of the dehydration tank 30. At this time, since the washing and rinsing administration is performed in a state in which sufficient amount is supplied only to the dehydration tank 30 in which the laundry is actually loaded, the amount of washing water as well as detergent is significantly reduced.

이러한 세탁 및 헹굼행정이 완료된 후, 배수밸브(51)가 개방되면 탈수조(30) 내의 세탁수는 배수홀(361)과 배수호스(50)를 통해 외부로 배수된다. 이러한 배수행정시에는 배수밸브(51)가 개방된 상태이기 때문에, 수조(20) 내의 세탁수가 배수호스(50)를 통해 배수됨에 따라 부력부재(38)가 내려앉고, 개방된 배수홀(361)을 통해 탈수조(30)내의 세탁수도 외부로 배출된다.After the washing and rinsing stroke is completed, when the drain valve 51 is opened, the wash water in the dehydration tank 30 is drained to the outside through the drain hole 361 and the drain hose 50. Since the drain valve 51 is in an open state during the drainage stroke, the buoyancy member 38 falls down as the wash water in the water tank 20 is drained through the drain hose 50, and the drain hole 361 that is open. Through the wash water in the dehydration tank 30 is also discharged to the outside.

그리고 탈수행정시에는 탈수조(30)와 펄세이터(34)가 동시에 일방향으로 고속회전함으로써, 세탁물 탈수가 이루어진다. 즉, 탈수조(30)의 고속회전으로 인해 세탁물에 함유된 물은 도 6에 도시한 바와 같이, 세탁물과 탈수조(30) 벽면을 따라 상측으로 올라가고 상단부에 형성된 탈수공(311)을 통해 배출된다. 계속하여 탈수공(311)을 통해 탈수된 물은 수조(20) 바닥면으로 흘러 내려가고, 배수호스(50)를 통해 하우징(10) 외부로 배출된다.In the dehydration administration, the dehydration tank 30 and the pulsator 34 rotate at the same time in one direction at a high speed, so that laundry is dewatered. That is, the water contained in the laundry due to the high-speed rotation of the dehydration tank 30 rises upward along the laundry and the wall of the dehydration tank 30, as shown in FIG. 6, and is discharged through the dehydration hole 311 formed at the upper end. do. Subsequently, the water dehydrated through the dehydration hole 311 flows down to the bottom surface of the water tank 20 and is discharged to the outside of the housing 10 through the drain hose 50.

이상에서 상세히 설명한 바와 같이, 본 발명이 적용된 세탁기는 세탁 및 헹굼행정시 실제 세탁물이 담겨지는 탈수조 내에 적당량의 세탁수가 급수되며, 수조 내에 탈수조 수위보다 낮은 세탁수가 유입됨으로써, 세탁 및 헹굼행정시 요구되는 물 소비량이 월등하게 감소된다.As described above in detail, the washing machine to which the present invention is applied is supplied with an appropriate amount of washing water in a dehydration tank in which actual laundry is contained during washing and rinsing administration, and the washing water lower than the dehydration tank level flows into the tank, thereby washing and rinsing administration. The water consumption required is greatly reduced.

또한, 급수시간의 감소로 인해 소비전력이 줄어드는 것은 물론이며, 물과 함께 세제 사용량도 줄어 생활폐수에 의한 수질오염을 줄일 수 있는 이점이 있다.In addition, the power consumption is reduced due to the reduction of the water supply time, as well as the amount of detergent is reduced along with the water has the advantage of reducing the water pollution caused by domestic wastewater.
