Description

드럼세탁기의 터브몸체와 커버간의 시일링구조Sealing structure between tub body and cover of drum washing machine

본 발명은 드럼세탁기에 관한 것으로서 특히, 드럼세탁기의 터브몸체와 커버사이로 결합되는 시일링의 외주면에 여러개의 돌기를 형성하여 한쪽면이 누수가 되더라도 다른의 돌기들에 의해 2중으로 시일링되도록 함으로서 세탁수가 누수되는 것을 방지할수 있는 드럼세탁기의 터브몸체와 커버간의 시일링구조에 관한 것이다.The present invention relates to a drum washing machine, in particular, by forming a plurality of protrusions on the outer peripheral surface of the sealing ring coupled between the tub body and the cover of the drum washing machine so that even if one side is leaked by double sealing by the other protrusions It relates to a sealing structure between the tub body and the cover of the drum washing machine to prevent water leakage.

종래의 드럼세탁기에서 세탁수를 담고 있는 세탁조의 터브몸체(2)와 커버(3) 사이에 세탁수가 누수되지 않토록 도1 및 도2와 같이 시일링(1)이 결합되어진다.In the conventional drum washing machine, the sealing ring 1 is coupled as shown in FIGS. 1 and 2 so that the washing water does not leak between the tub body 2 and the cover 3 of the washing tank containing the washing water.

상기 터브몸체(2)에는 대개 반 이내로 세탁수가 채워지기 때문에 수압이 많이 걸리지는 않지만 가열세탁을 하게 되면 내부압력이 상승하게 되어 커버(3)의 안착홈(4)에 결합된 시일링(1)에 상당한 압력이 걸리게 된다.Since the tub body (2) is usually filled with the washing water in less than half, it does not take much water pressure, but when the washing is heated, the internal pressure rises, the sealing ring (1) coupled to the seating groove (4) of the cover It will take considerable pressure.

그리고, 상기의 시일링(1)이 압력에 견디질 못하면 세탁수가 누수 되어지게 된다.If the seal ring 1 does not withstand the pressure, the wash water is leaked.

상기의 세탁수가 누수되면 세탁기의 기능에 장애가 발생함은 물론 안전에도 심각한 결과를 초래 할수 있게 되므로 드럼세탁기에서 완벽한 시일링구조를 안출하는 것은 매우 중요한 과제라 할수 있다.When the wash water leaks, the function of the washing machine may be impaired as well as cause serious consequences for safety. Therefore, it may be a very important task to create a perfect sealing structure in the drum washing machine.

종래 스테인레스로 만들어진 세탁기의 시일링은 도1에 나타낸 바와같이 사다리꼴 형상으로된 시일링(1)이 많이 사용되고 있다.Conventionally, the sealing ring of a washing machine made of stainless steel has a seal ring 1 having a trapezoidal shape as shown in FIG. 1.

상기의 시일링(1)은 단면적이 크기 때문에 안착홈(4)내의 좁은공간내에서는 장착의 어려운이 많았었고 시일링효과도 뒤떨어지는 문제점을 가지고 있었다.Since the sealing ring 1 has a large cross-sectional area, it is difficult to install in a narrow space in the seating groove 4, and the sealing effect is also inferior.

상기의 사다리꼴 형상으로된 시일링(1)의 단점을 보완하기 위하여 출현된 것이 도2와 같은 소형의 오링(11)이다.The small O-ring 11 as shown in FIG. 2 has appeared to compensate for the above-mentioned drawbacks of the trapezoidal seal ring 1.

상기의 오링(11)은 내부가 완전히 채워진 타입과 내부가 중공으로된 타입으로 나뉘어져 사용되고 있는바, 상기 내부가 중공으로된 오링(11)은 상대적으로 작은힘에 의해 눌려도 시일링이 잘 유지되므로 원둘레가 큰 드럼세탁기의 경우는 중공타입의 오링(11)을 많이 사용하고 있다.The O-ring 11 is divided into a type that is completely filled inside and a type that is inside the hollow bar, since the O-ring 11 inside the hollow is kept well even when pressed by a relatively small force In the case of a drum washing machine having a large circumference, a hollow o-ring 11 is often used.

그러나, 상기 오링(11)의 접착면에 이물질이 묻어 있거나 커버(3)의 안착홈(4)내부로 잘못 부착되면 그 틉새로 누수가 되는 문제점을 가지고 있었다.However, if the foreign material is attached to the adhesive surface of the O-ring 11 or incorrectly attached to the inside of the seating groove 4 of the cover 3, there was a problem of leaking.

이러한 종래의 문제점 등을 해결 보완 하기 위한 본고안의 목적은, 드럼세탁기의 터브몸체와 커버의 사이를 완벽하게 시일링하여 세탁수가 누수되는 것을 방지할수 있도록 하는 목적을 제공한다.The purpose of the present invention for solving the conventional problems and the like, to provide a purpose to prevent the wash water leakage by completely sealing between the tub body and the cover of the drum washing machine.

본 발명의 구성을 도3에 의해 상세히 설명 하기로 한다.The configuration of the present invention will be described in detail with reference to FIG.

드럼세탁기의 터브몸체(105)와 커버(106)사이로 세탁수가 누수되는 것을 방지하기 위하여 커버(106)의 안착홈(107)내부로 결합되는 중공부(102)가 형성된 시일링(101)과, 상기 시일링(101)의 한쪽면에 누수가 발생되더라도 다른면에 의해 시일링 되도록 하기 위하여 시일링(101)의 외주면에 돌설되는 다수개의 돌기(103)를 구비한 구성이다.A sealing ring 101 having a hollow portion 102 coupled to the inside of the seating groove 107 of the cover 106 in order to prevent the wash water from leaking between the tub body 105 and the cover 106 of the drum washing machine; Even if a leakage occurs on one side of the seal ring 101 is configured with a plurality of protrusions 103 protruding on the outer peripheral surface of the seal ring 101 to be sealed by the other side.

그리고, 상기 시일링(101)의 외주면에 돌설된 돌기(103)들을 커버(106)의 안착홈(107)3면과 터브몸체(105)1면에 각각 2개씩 접촉을 하도록 형성시켰다.In addition, the protrusions 103 protruding from the outer circumferential surface of the seal ring 101 were formed to come into contact with two seating grooves 107 and three tub body 105 surfaces of the cover 106, respectively.

또한, 상기의 시일링(101)은 터브몸체(105)의 커버(106)가 압축될 때 상,하측부가 팽창하여 커버(106)에 형성된 안착홈(107)상,하측면을 밀착시킬수 있도록 하기 위하여 시일링(101)의 좌,우측두께(t2)보다 상,하측두께(t1)를 얇게 형성시켰다.In addition, the seal ring 101 is to be in close contact with the upper and lower portions when the cover 106 of the tub body 105 is compressed so that the upper and lower surfaces on the seating groove 107 formed in the cover 106 in close contact with each other. To this end, the upper and lower thicknesses t1 were formed thinner than the left and right thicknesses t2 of the seal ring 101.

그리고, 상기 시일링(101)을 커버(106)의 안착홈(107)에 결합하여 접착시에 오접착을 방지 하기 위하여 시링일(101)의 중공부(102)일측에 돌설되는 오접착방지용돌기(104)를 더 구비하였다.Then, the sealing ring 101 is coupled to the seating groove 107 of the cover 106 to prevent erroneous adhesion during adhesion to prevent the mis-adhesion projection protruding on one side of the hollow portion 102 of the sealing ring 101 (104) was further provided.

이와같이된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as described above is as follows.

일반적으로 세탁조 내부의 세탁수는 터브몸체(105)의 벽면을 따라 누수될수도 있고 커버(106)의 내면을 따라 누수 될수도있다.In general, the washing water inside the washing tank may leak along the wall of the tub body 105 or may leak along the inner surface of the cover 106.

그러나, 본 발명 커버(106)의 안착홈(107)에 안착된 시일링(101)은 3개의 면에 돌설된 돌기(103)들이 안착홈(107)의 3면을 시일링 하고 있고 1면에 돌설된 돌기(103) 들이 터브몸체(105)와 1면을 접촉하면서 시일링하고 있다.However, the sealing ring 101 seated in the seating groove 107 of the cover 106 of the present invention seals the three sides of the seating groove 107 with the protrusions 103 protruding on three sides and on one side. Protruding protrusions 103 are sealing while contacting the tub body 105 and one surface.

따라서, 상기 터브몸체(105)나 커버(106)중 어느 한쪽면에 누수가 발생되더라도 다른면에 형성된 돌기(103)들에 의해 누수를 차단하게 되므로 외부로 세탁수가 흘러나오는 일이 없게 된다.Therefore, even if a leak occurs on either side of the tub body 105 or the cover 106, the leak is blocked by the protrusions 103 formed on the other side, so that the wash water does not flow out.

특히, 상기의 터브몸체(105)의 1면과 커버(106)의 안착홈3개면을 2개씩의 돌기(103)들이 접촉을 하고 있기 때문에 1개의 돌기(103)에서 누수가 되더라도 다른1개의 돌기(103)에 의해 누수를 완벽하게 차단할수 있게 된다.In particular, since the two projections 103 are in contact with one surface of the tub body 105 and three surfaces of the seating groove of the cover 106, the other projection is leaked by one projection 103. By 103, the leak can be completely blocked.

또한, 상기의 시일링(101)은 상,하측면의 두께(t1)가 얇고 좌,우측면의 두께(t2)가 상,하측면보다 두껍게 형성되어 있기 때문에 터브몸체(105)와 커버(106)가 압축할 때 상,하측면이 팽창하여 안착홈(107)의 상,하측면으로 밀착하게 되므로 더욱 확실한 누수차단을 할 수 있게된다.In addition, the seal ring 101 has a tub body 105 and a cover 106 because the upper and lower surfaces have a thin thickness t1 and the left and right surfaces have a larger thickness t2 than the upper and lower surfaces. When compressed, the upper and lower sides are expanded so as to be in close contact with the upper and lower sides of the seating groove 107, so that more reliable leakage blocking can be achieved.

그리고, 상기 시일링(101)의 중공부(102)일측부에 돌설된 오접착방지용돌기(104)에 의해 시일링(101)을 정확한 위치로 접착시킬수 있게 되므로 시일링(101)의 오접착으로 인한 뒤틀림을 막을 수 있게된다.Further, since the sealing ring 101 can be adhered to the correct position by the erroneous adhesion preventing protrusion 104 protruding from one side of the hollow part 102 of the sealing ring 101, the sealing ring 101 may be incorrectly bonded. It can prevent the distortion.

또한, 상기 시일링(101)의 뒤틀림을 막아줌으로 인해 시일링효과를 더욱 향상시킬 수 있게 된다.In addition, it is possible to further improve the sealing effect by preventing the distortion of the sealing ring 101.

이와같이된 본 발명은 시일링의 외주면에 형성된 다수개의 돌기들에 의해 보다 신뢰성있는 시일링 효과를 기대할 수 있게 되고 보다 향상된 시일링 효과에 의해 터브 몸체와 커버간의 누수를 완벽하게 막을 수 있는 유용한 효과를 갖는다.As described above, the present invention can expect a more reliable sealing effect by a plurality of protrusions formed on the outer circumferential surface of the sealing, and a useful effect that can completely prevent leakage between the tub body and the cover by the improved sealing effect.
