종래의 전자동세탁기는 제1도에 나타낸 바와 같이, 외조(1a)내부에 내조인 세탁겸용 탈수조(2a)가 회전가능하게 설치되고, 탈수조(2a)의 하부에는 회전자(8a)가 설치되며, 상기 탈수조(2a) 및 회전자(8a)에는 외조(1a)의 저면에 설치된 클러치(10)의 탈수축(9a) 및 세탁축(9b)이 관통하여 각각 체결되고, 상기 외조(1a)의 저면일측에 설치된 모터(11)와 클러치(10)에는 각각 모터플리(12) 및 V-벨트플리(13)가 설치되어 V-밸트(14)가 감겨서 전동되도록 구성된다.In the conventional fully automatic washing machine, as shown in FIG. 1, a washing / drying dehydration tank 2a, which is internally tanked inside the outer tank 1a, is rotatably installed, and a rotor 8a is installed below the dewatering tank 2a. The dehydration tank 2a and the rotor 8a penetrate through the dehydration shaft 9a and the washing shaft 9b of the clutch 10 installed on the bottom surface of the outer tub 1a, respectively, and the outer tub 1a. The motor 11 and the clutch 10 installed on one side of the bottom surface of the c) are provided with a motor fleece 12 and a V-belt fleece 13, respectively, so that the V-belt 14 is wound and transmitted.

그러나,이와 같은 종래의 전자동세탁기에서 세탁시 수조를 밀폐시킨 상태에서 운전을 하는 세탁 메카니즘을 채용할 경우 효율적인 원심탈수를 하기 위한 부가적인 탈수메카니즘을 설치해서 사용해야 하므로 인해 복잡한 구조로 인한 부품수가 많이 들어 조립시간 및 제작비용이 많이 소요되는 등의 문제점이 있었다.However, when adopting a washing mechanism that operates in a state in which the water tank is sealed when washing in the conventional fully automatic washing machine, it is necessary to install and use additional dehydration mechanism for efficient centrifugal dehydration. There was a problem such as high assembly time and manufacturing cost.

본 발명은 상기한 제반문제점을 해결하기 위한 것으로서, 본 발명은 원심탈수를 하는 전자동세탁기의 탈수시 간단한 최소한의 기구적인 구조로서 효율적인 탈수를 수행할 수 있도록 하여 제작단자를 경감시킬 수 있을 뿐만 아니라, 생산성을 향상시킬 수 있는 전자동세탁기의 탈수장치를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention can reduce the production terminal by enabling efficient dehydration as a simple minimal mechanical structure when dewatering the fully automatic washing machine for centrifugal dehydration, An object of the present invention is to provide a dehydration apparatus for a fully automatic washing machine that can improve productivity.

상기한 목적을 달성하기 위해 본 발명은 배수공이 형성되는 내조와, 상기 배수공을 탈수 및 세탁시 개폐시키기 위한 원심배수밸브가 부착되어 내조에 탄력 설치되는 탄성체로 구성된 전자동세탁기의 탈수장치이다.In order to achieve the above object, the present invention is a dewatering device of a fully automatic washing machine composed of an inner tank in which a drain hole is formed, and an elastic body elastically installed in the inner tank by attaching a centrifugal drain valve for opening and closing the drain hole during dehydration and washing.

이하, 본 발명의 일실시예를 첨부도면 제2도 및 제3도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3 of the accompanying drawings.

제2도는 본 발명을 나타낸 종단면도이고, 제3도는 제2도 A부분의 작동상태를 나타낸 확대 종단면도로서, 전자동세탁기의 외조(1)내에 설치된 내조(2)의 상단에 내조밀폐 커버(3)가 결합되고, 상기 내조(2)의 상부 둘레면에는 복수개의 배수공(4)이 형성되며, 상기 내조(2)의 상부 양측에는 일단이 내조(2)에 체결부재(5)로서 고정되고, 타단에는 배수공(4)을 탈수 및 세탁시 탄성력에 의해 개폐시키기 위한 원심배수밸브(6)가 부착된 탄성체(7)가 탄력 설치되어 구성된다.FIG. 2 is a longitudinal cross-sectional view showing the present invention, and FIG. 3 is an enlarged vertical cross-sectional view showing an operating state of part A of FIG. 2, and the airtight sealing cover 3 is placed on the upper end of the inner tub 2 installed in the outer tub 1 of the automatic washing machine. ) Is coupled, a plurality of drain holes 4 are formed in the upper circumferential surface of the inner tank 2, one end is fixed to the inner tank 2 as a fastening member 5 on both upper sides of the inner tank 2, At the other end, an elastic body 7 having a centrifugal drain valve 6 for opening and closing the drain hole 4 by elastic force during dehydration and washing is elastically installed.

이와 같이 구성된 본 발명은 제2도 및 제3도에 나타낸 바와 같이, 본 발명의 동작을 세탁 및 탈수모드로 나누어 설명하면 다음과 같다.The present invention configured as described above is illustrated in FIG. 2 and FIG. 3 by dividing the operation of the present invention into washing and dehydration modes as follows.

전자동세탁기의 세탁시에는 내조(2)내의 하부에 설치된 진동자(8)의 진동에 의해 상기 내조(2)안은 세탁상태가 되며, 내조(2)의 상단에 결합된 내조밀폐커버(3), 상기 내조(2)의 상부 양측에 일단이 체결부재(5)로서 고정되고, 타단에 원심배수밸브(6)가 부착된 탄성체(7)의 복원력에 의해 상기 내조(2)의 상부 둘레면에 형성된 배수공(4)이 제3도의 (a)와 같이 닫히게 되므로 인해 물과 세탁물은 내조(2)안에서 유동하게 되는데, 이때 각각의 배수공(4)에 대한 작용력 F는 F=PA(P : 원심배수밸브에 가해지는 단위면적당의 압력, A : 배수공의 단면적), 탄성체(7)의 복원력R은 R=kxo(k : 탄성체의 탄성계수, xo: 탄성체의 초기변위량), (탄성체의 복원력 R)＞(내조안의 내부압력 P)의 상태가 되도록 탄성체(7)를 설계하므로써 배수공(4)은 항상 닫혀있게 되어 세탁행정을 수행할 수 있게 된다.During washing of the automatic washing machine, the inner tank 2 is washed by the vibration of the vibrator 8 installed at the lower part of the inner tank 2, and the inner tight sealing cover 3 coupled to the upper end of the inner tank 2, One end is fixed to the upper both sides of the inner tank (2) as a fastening member (5), the drain hole formed in the upper circumferential surface of the inner tank (2) by the restoring force of the elastic body (7) attached to the other end centrifugal drain valve (6) Since (4) is closed as shown in (a) of FIG. 3, water and laundry flow in the inner tank (2), where the force F for each drain hole (4) is equal to F = PA (P: centrifugal drain valve). Pressure per unit area applied, A: cross-sectional area of drain hole), restoring force R of elastic body 7 is R = kx o (k: elastic modulus of elastic body, x o : initial displacement of elastic body), (restoring force R of elastic body)> By designing the elastic body 7 to be in the state of (internal pressure P in the inner tank), the drainage hole 4 is always closed and the washing stroke is performed. It can be so.

또한, 탈수시에는 외조(1)는 고정되고, 모터(도시는 생략함)의 회전력을 받아 내조(2)는 회전하여 원심력을 받게 되는데, 모터의 회전수가 일정치에 도달하면, 내조압력(P)과 원심력(F)의 합이 탄성체(7)의 복원력(R)을 초과하지 시작하여 이 이상의 회전수를 계속받게 되면 탄성체(7)에 부착된 원심배수밸브(6)는 탄성체(7)의 복원력을 이기고 젖혀지게 되어 제3도의 (b)와 같이 배수공(4)이 열리게 되고, 계속해서 원심력에 의해 물은 테이퍼진 내조(2)의 경사면을 따라 회전축(9)으로부터 가장 거리가 먼 배수공(4)까지 이르게 되어 배수공(4)을 통해 외조(1)로 유출되므로 정상탈수시 효율적인 탈수행정을 수행할 수 있게 된다.In addition, during dehydration, the outer tub 1 is fixed and receives the rotational force of the motor (not shown), and the inner tub 2 is rotated to receive centrifugal force. When the rotational speed of the motor reaches a predetermined value, the inner tub pressure P ) And when the sum of centrifugal force (F) starts not exceeding the restoring force (R) of the elastic body (7) and continues to receive more rotations than the centrifugal drain valve (6) attached to the elastic body (7) The drainage hole 4 is opened as shown in (b) of FIG. 4) to reach the outer tank (1) through the drain hole (4) it is possible to perform an efficient dehydration stroke during normal dehydration.

즉, 원심력(F)+내조내부압력(P)＞탄성체의 복원력(R)That is, centrifugal force (F) + inner bath internal pressure (P)> restoring force (R) of the elastic body

상기의 세탁 및 탈수모드를 만족하는 탄성체는The elastic body that satisfies the washing and dehydration mode is

P ＜ R ＜ (F+P)P <R <(F + P)

(내조안의 압력) (탄성체의 복원력) (원심력+내조압력)(Pressure in inner tank) (restoring force of elastic body) (centrifugal force + inner pressure)

이므로 복원력이 상기 범위에 속하는 탄성체(7)를 설치하므로써 세탁 및 탈수모드를 효율적으로 수행할 수 있게 된다.Therefore, the restoring force can be efficiently carried out by washing and dehydration mode by installing the elastic body 7 belonging to the above range.

한편, 본 발명의 다른 실시예로서 제4도의 (a) 및 (b)에 나타낸 바와 같이, 내조(2)의 중앙 및 하단 둘레면에 복수개의 배수공(4)을 형성시키고, 배수공(4)을 탈수 및 세탁시 탄성력에 의해 개폐시키기 위한 원심배수밸브(6)가 부착된 탄성체(7)를 탄력 설치하여 사용하므로써 본 발명과 동일한 효과를 얻을 수 있게 된다.On the other hand, as shown in (a) and (b) of FIG. 4 as another embodiment of the present invention, a plurality of drain holes 4 are formed in the center and the lower circumferential surface of the inner tank 2, and the drain holes 4 are formed. By elastically installing and using the elastic body 7 with the centrifugal drain valve 6 for opening and closing by elastic force during dewatering and washing, the same effect as the present invention can be obtained.

이상에서와 같이, 본 발명은 내조(2) 상부 둘레면의 배수공(4)을 탈수 및 세탁시 개폐시키기 위한 원심배수밸브(6)가 부착된 탄성체(7)가 내조(2)에 탈력설치 되므로써, 탈수시 최소한의 기구적인 구조로서 효율적인 탈수행정을 수행할 수 있어서 부품수의 감소로 인한 제작비용을 절감시킬 수 있을 뿐만 아니라, 생산성을 증대시킬 수 있으므로 인해 제품의 효율성 및 신뢰성을 대폭 향상시킨 매우 유용한 발명이다.As described above, in the present invention, the elastic body 7 with the centrifugal drain valve 6 for opening and closing the drain hole 4 on the upper circumferential surface of the inner tank 2 is detached from the inner tank 2 so that When dewatering, it is possible to carry out efficient dehydration administration with minimal mechanical structure, which not only reduces the manufacturing cost due to the reduction of the number of parts, but also increases productivity, which greatly improves the efficiency and reliability of the product. It is a useful invention.
