세탁기용 워터씰{THE WATER SEAL FOR WASHING MACHINE}Water seal for washing machine {THE WATER SEAL FOR WASHING MACHINE}

본 고안은 세탁기의 세탁조와 세탁조를 회전시키기 위한 기어장치의 연결부에 설치되어 세탁조 내의 물이 기어장치로 유입되는 것을 방지하는 세탁기용 워터씰에 관한 것이다.The present invention relates to a water seal for a washing machine installed at the connection portion of the washing machine and the gear unit for rotating the washing tank to prevent water in the washing tank from entering the gear device.

일반적으로 전동세탁기는 세탁물과 물이 투입되어 세탁물의 세탁이 이루어지는 용기 형상의 세탁조(1)를 가지고 있다. Generally, the electric washing machine has a container-shaped washing tank 1 in which laundry and water are put in and washing laundry.

또, 세탁조(1)를 회전시키기 위해 모터 등을 갖는 회전력발생수단을 가지고 있다. Moreover, it has the rotational force generation means which has a motor etc. in order to rotate the washing tank 1. As shown in FIG.

또, 회전전력발생수단에 의해 발생된 회전력을 세탁조(1)에 전달하여 세탁조가 세탁을 위한 형태로 움직이도록(회전하도록) 하는 기어장치(2)를 가지고 있다.It also has a gear device 2 which transmits the rotational force generated by the rotational power generating means to the washing tub 1 so that the washing tub moves (rotates) in the form for washing.

상기와 같은 전동세탁기의 구조에서 세탁조(1) 내의 물이 기어장치(2)로 유입되는 것을 방지하기 위해 워터씰(3)이 설치되고 있다.In the structure of the electric washing machine as described above, the water seal 3 is installed to prevent water in the washing tank 1 from flowing into the gear device 2.

일반적으로 세탁기용 워터씰은 외경부가 세탁조(1)에 고정되고 내경부는 동 력을 전달받아 회전되는 회전축이 삽입되는 형태로 설치된다. In general, the water seal for the washing machine is installed in a shape in which the outer diameter is fixed to the washing tank (1) and the inner diameter is inserted into a rotating shaft that is rotated by receiving power.

즉, 종래의 세탁기용 워터씰은, 세탁조(1)로 회전력을 전달하는 회전축이 삽입되고, 회전축(4)에 밀착되는 립(3a)을 갖는 내경부를 가지고 있는 것이다.That is, the conventional water seal for washing machine has an inner diameter portion having a lip 3a in which a rotating shaft for transmitting rotational force to the washing tank 1 is inserted and in close contact with the rotating shaft 4.

또, 세탁조(1)에 형성된 워터씰삽입홈(1a)에 삽입되고 워터씰삽입홈(1a)에 밀착되는 립(3b)을 갖는 외경부를 가지고 있는 것이다.Moreover, it has an outer diameter part which has the lip 3b inserted in the water seal insertion groove 1a formed in the washing tank 1, and in close contact with the water seal insertion groove 1a.

또, 내경부와 외경부 사이에 형성되어 있고, 기어장치(2)의 구성요소인 하우징(2a)이 삽입되는 하우징삽입홈(3c)을 가지고 있는 것이다.Moreover, it has between the inner diameter part and the outer diameter part, and has the housing insertion groove 3c in which the housing 2a which is a component of the gear apparatus 2 is inserted.

그런데 종래의 세탁기용 워터씰은 오랫동안 사용되지 못하고 파손이 빈번하게 발생되는 문제점이 있었다. By the way, the conventional water seal for a washing machine did not use for a long time there was a problem that frequently occurs breakage.

워터씰의 파손은 누수방지 기능을 온전히 수행하지 못하게 되는 경우도 많았으며, 누수방지 기능을 유지하더라고 소음과 진동을 크게 발생시키는 정도의 것이었다. In many cases, the water seal was not able to perform the leak prevention function completely, and the noise seal was largely generated even though the leak preventing function was maintained.

세탁기용 워터씰 파손의 주요원인은 세탁조의 구동(세탁공정과 탈수공정 등을 위한 회전 등)시 발생되는 진동 및 마찰력이었다. The main causes of water seal breakage for washing machines were vibration and frictional forces generated during the operation of the washing tank (rotation for washing and dewatering processes, etc.).

즉, 잦은 진동과 마찰로 인해 워터실의 형상이 변형되고 마모가 발생되어 누수가 발생되기도 하고, 소음도 발생되었던 것이다.In other words, due to frequent vibration and friction, the shape of the water seal is deformed and abrasion occurs, which causes water leakage and noise.

종래의 워터씰에서 진동 및 마찰에 특히 취약한 부분이 워터씰의 하우징삽입홈이었다.Particularly vulnerable to vibration and friction in the conventional water seal was the housing insertion groove of the water seal.

본 고안은 상기와 같은 문제점을 해소하려는 것으로서, 더욱 상세하게는 세탁조의 구동시 발생되는 진동 및 마찰에 의한 파손발생률을 크게 낮출 수 있는 세탁기용 워터씰의 구조를 제공하려는데 목적이 있다.The present invention is intended to solve the above problems, and more particularly, to provide a structure of a water seal for a washing machine that can greatly reduce the breakage rate caused by vibration and friction generated when driving the washing tank.

본 고안에서는 워터씰의 내경부와 외경부 사이에 환형의 강도보강용 철심이 위치되도록 하고, 강도보강용 철심이 하우징삽입홈의 내측면을 형성하고, 하우징삽입홈의 외측면은 기어장치의 구성요소인 하우징과 접촉되는 부분과 접촉되지 않는 부분을 갖도록 요철 형태로 구현하여 진동 및 마찰에 강한 하우징삽입홈이 되도록 하고, 이로 인해 진동 및 마찰에 의한 파손발생률이 낮은 워터씰이 되도록 한다.In the present invention, the annular strength reinforcing iron core is positioned between the inner diameter portion and the outer diameter portion of the water seal, the strength reinforcing iron core forms the inner side of the housing insertion groove, and the outer side of the housing insertion groove is the gear device. Implemented in the form of unevenness to have a portion that is not in contact with the housing that is the element to be a housing insertion groove resistant to vibration and friction, thereby resulting in a water seal with a low incidence of damage caused by vibration and friction.

이러한 본 고안의 세탁기용 워터씰은, 세탁조로 회전력을 전달하는 회전축이 삽입되고, 회전축에 밀착되는 복수 개의 립을 갖는 내경부를 갖는다.The water seal for a washing machine of the present invention has an inner diameter portion having a plurality of ribs in which a rotating shaft for transmitting rotational force to a washing tank is inserted and in close contact with the rotating shaft.

또, 세탁조에 형성된 워터씰삽입홈에 삽입되고 워터씰삽입홈에 밀착되는 복수 개의 립을 갖는 외경부를 갖는다. It also has an outer diameter portion having a plurality of lip inserted into the water seal insertion groove formed in the washing tank and in close contact with the water seal insertion groove.

또, 내경부와 외경부 사이에 형성되어 있고, 기어장치의 구성요소인 하우징이 삽입되는 하우징삽입홈을 갖는다.It is provided between the inner diameter part and the outer diameter part, and has the housing insertion groove into which the housing which is a component of a gear apparatus is inserted.

또, 내경부와 외경부 사이에 위치된 환형의 강도보강용 철심을 갖는다. It also has an annular strength reinforcing iron core located between the inner diameter portion and the outer diameter portion.

또, 강도보강용 철심이 상기 하우징삽입홈의 내측면을 형성하고 있고, 하우 징삽입홈의 외측면은 요철 형태로 되어 있어 기어장치의 구성요소인 하우징과 접촉되는 부분과 접촉되지 않는 부분을 갖는다.In addition, the steel core for strength reinforcement forms the inner surface of the housing insertion groove, and the outer surface of the housing insertion groove has a concave-convex shape, and has a portion which is not in contact with the housing which is a component of the gear device. .

본 고안의 세탁기용 워터씰은, 워터씰의 내경부와 외경부 사이에 환형의 강도보강용 철심이 위치되며, 강도보강용 철심이 하우징삽입홈의 내측면을 형성하고, 하우징삽입홈의 외측면은 기어장치의 구성요소인 하우징과 접촉되는 부분과 접촉되지 않는 부분을 갖도록 요철 형태로 구현되어 있다.In the water seal for a washing machine of the present invention, an annular strength reinforcing iron core is positioned between an inner diameter portion and an outer diameter portion of the water seal, the strength reinforcing iron core forms an inner side surface of the housing insertion groove, and an outer side surface of the housing insertion groove. The concave and convex shape is implemented to have a portion that is not in contact with the housing which is a component of the gear device.

따라서 본 고안의 세탁기용 워터씰은 진동 및 마찰에 강한 하우징삽입홈을 가지며, 이로 인해 진동 및 마찰에 의한 파손발생률이 낮은 특징이 있다.Therefore, the water seal for a washing machine of the present invention has a housing insertion groove resistant to vibration and friction, and thus has a low occurrence rate of breakage due to vibration and friction.

이하, 본 고안의 기술적 사상을 더욱 구체적으로 설명한다. Hereinafter, the technical spirit of the present invention will be described in more detail.

그러나 첨부된 도면은 본 고안의 기술적 사상을 더욱 구체적으로 설명하기 위하여 도시한 일 예에 불과하므로 본 고안의 기술적 사상이 첨부된 도면의 형태에 한정되는 것은 아니다. However, the accompanying drawings are only examples to illustrate the technical idea of the present invention in more detail, and thus the technical idea of the present invention is not limited to the accompanying drawings.

본 고안은 세탁기용 워터씰에 관한 것이다. The present invention relates to a water seal for a washing machine.

따라서 본 고안의 세탁기용 워터씰도 종래기술에서와 같이 세탁조(1)로 회전력을 전달하는 회전축(4)이 삽입되고, 회전축(4)에 밀착되는 립(11)을 갖는 내경부(10)를 갖는다. Therefore, the water seal for the washing machine of the present invention also has an inner diameter portion 10 having a lip 11 in close contact with the rotating shaft 4 is inserted into the rotating shaft 4 to transmit the rotational force to the washing tank 1 as in the prior art. Have

또, 세탁조(1)에 형성된 워터씰삽입홈(1a)에 삽입되고 워터씰삽입홈(1a)에 밀착되는 립(21)을 구비한 외경부(20)를 갖는다.Moreover, it has the outer diameter part 20 provided with the lip 21 inserted in the water seal insertion groove 1a formed in the washing tank 1, and closely_contact | adhered to the water seal insertion groove 1a.

또, 내경부(10)와 외경부(20) 사이에 형성되어 있고, 기어장치(2)의 구성요소인 하우징(2a)이 삽입되는 하우징삽입홈(30)을 갖는다. Moreover, it has a housing insertion groove 30 which is formed between the inner diameter part 10 and the outer diameter part 20, and into which the housing 2a which is a component of the gear device 2 is inserted.

그런데 본 출원은 세탁조(1)의 구동시 발생되는 진동 및 마찰에 의한 파손발생률이 매우 낮은 세탁기용 워터씰을 제공하려는 목적을 갖는다.However, the present application has an object to provide a water seal for a washing machine having a very low incidence of breakage due to vibration and friction generated when the washing tub 1 is driven.

이를 위하여 본 고안의 워터씰은 내경부(10)와 외경부(20) 사이에 환형의 강도보강용 철심(40)이 위치되도록 한다.('철심'이라고 표현한 것은 금속 재질이기 때문이다.)To this end, the water seal of the present invention allows the annular strength reinforcing iron core 40 to be positioned between the inner diameter portion 10 and the outer diameter portion 20 (since it is expressed as 'iron core').

그러나 상기와 같은 강도보강용 철심(40)이 내구성을 향상시켜줄 수는 있으나 그러한 구성만으로는 본 고안의 목적을 달성할 수 없다.However, the strength reinforcing iron core 40 as described above can improve the durability, but such a configuration alone can not achieve the purpose of the present invention.

본 출원의 고안자는 오랜 연구와 노력 끝에 도 4와 같이 내경부(10)와 외경부(20) 사이에 위치된 환형의 강도보강용 철심(40)이 하우징삽입홈(30)의 내측면을 형성하고, 하우징삽입홈(30)의 외측면은 기어장치(2)의 구성요소인 하우징(2a)과 접촉되는 부분과 접촉되지 않는 부분을 갖도록 요철 형태로 되어 있는 구조를 안출하였다. The inventors of the present application, after a long study and effort, as shown in FIG. 4, an annular strength reinforcing iron core 40 located between the inner diameter portion 10 and the outer diameter portion 20 forms the inner surface of the housing insertion groove 30. In addition, the outer surface of the housing insertion groove 30 is devised in a concave-convex shape such that the outer surface of the housing insertion groove 30 has a portion that is not in contact with the housing 2a which is a component of the gear device 2.

이러한 구조에 의하면, 기어장치(2)의 구성요소인 하우징(2a)과 워터씰의 조립부에서 파손이 발생되는 것을 방지할 수 있다. According to this structure, damage can be prevented from occurring in the assembly portion of the housing 2a and the water seal, which are components of the gear device 2.

즉, 세탁조(1)의 구동시 기어장치(2)의 구성요소인 하우징(2a)과 접촉되는 하우징삽입홈(30)의 내측면과 외측면 특히, 내측면이 진동 및 마찰력에 의해 마모 되거나 파손되는 현상을 크게 방지할 수 있는 것이다.That is, the inner and outer surfaces of the housing insertion groove 30, in particular, the inner surface of the housing insertion groove 30, which are in contact with the housing 2a that is a component of the gear device 2 when the washing tub 1 is driven, are worn or damaged by vibration and frictional force. This can greatly prevent the phenomenon.

단순히 강도보강용 철심(40)이 하우징(2a)의 내측면을 형성하는 구조만으로는 진동 및 마찰에 의해 하우징삽입홈(30)이 마모되거나 파손되는 현상을 크게 방지할 수 없다.Only the structure in which the strength reinforcing iron core 40 forms the inner side surface of the housing 2a cannot greatly prevent a phenomenon in which the housing insertion groove 30 is worn or broken by vibration and friction.

본 고안에서와 같이 하우징삽입홈(30)의 외측면이 요철 형태로 되어 있음으로써 기어장치(2)의 구성요소인 하우징(2a)과 접촉되는 부분과 접촉되지 않는 부분을 가져야 하우징삽입홈(30)이 마모되거나 파손되는 것을 크게 낮출 수 있다. As in the present invention, the outer surface of the housing insertion groove 30 has a concave-convex shape so that the housing insertion groove 30 should have a portion that does not come into contact with the housing 2a which is a component of the gear device 2. ) Can greatly reduce wear and tear.

이러한 기술적 사상은 본 출원의 고안자가 오랜 연구와 노력 및 수많은 실패를 거듭하면서 안출한 것이다.This technical idea has been devised by the inventors of the present application through many years of research and efforts and numerous failures.

하우징삽입홈(30)의 외측면이 요철 형태로 되어 있기 때문에 세탁조(1)의 구동시 발생되는 편심하중에도 적절히 대처하여, 하중이 고르게 분포되도록 하는 것이다.Since the outer surface of the housing insertion groove 30 has an uneven shape, the load is evenly distributed so as to cope with the eccentric load generated when the washing tub 1 is driven.

상기 하우징삽입홈(30)의 외측면에 형성된 요철은 하우징삽입홈(30)의 상단부에서 하단부까지 연장 형성된 홈(31, 도 4참조)이 외주면을 따라 간격을 두고 형성된 형태가 바람직하다는 결과를 얻었다.The unevenness formed on the outer surface of the housing insertion groove 30 has a result that the grooves 31 (see FIG. 4) formed extending from the upper end portion to the lower end portion of the housing insertion groove 30 at intervals along the outer circumferential surface are obtained. .

또, 홈(31)은 하우징삽입홈(30)의 외주면을 따라 등간격(일정한 간격)으로 형성되는 것이 바람직하다는 결과를 얻었다.In addition, the groove 31 was obtained along the outer circumferential surface of the housing insertion groove 30 at equal intervals (constant interval).

본 고안에 있어서, 강도보강용 철심(40)은 내마모성이 기어장치(2)의 구성요소인 하우징(2a)과 동일한 것이 바람직하다. In the present invention, the strength reinforcing iron core 40 preferably has the same wear resistance as the housing 2a which is a component of the gear device 2.

이것은 기어장치(2)의 구성요소인 하우징(2a)과 접촉된 상태에서 마모가 발 생되는 것을 최소화할 수 있기 때문이다. This is because wear can be minimized in contact with the housing 2a, which is a component of the gear device 2.

물론, 가장 바람직한 것은 동일한 금속 재질로 구현하는 것이다.Of course, the most preferable is to implement the same metal material.

본 고안에 있어서, 강도보강용 철심(40)에 의해 하우징삽입홈(30)의 상부면이 형성되어 있는 것이 바람직하다.In the present invention, it is preferable that the upper surface of the housing insertion groove 30 is formed by the strength reinforcing iron core 40.

이것은 기어장치(2)의 구성요소인 하우징(2a)과 접촉된 상태에서 하우징삽입홈(30)의 상부면이 크게 마모되거나 파손되는 것을 방지할 수 있기 때문이다.This is because the upper surface of the housing insertion groove 30 can be prevented from being greatly worn out or broken in contact with the housing 2a, which is a component of the gear device 2.

마모현상의 방지 기능이 아니더라도 하우징삽입홈(30)의 상부면 모서리 부근에 집중되는 응력에 견딜 수 있는 특징이 있다.Even if it is not a function of preventing abrasion, there is a feature that can withstand the stress concentrated near the upper edge of the housing insertion groove (30).

본 고안에 있어서 내경부(10)의 립(11)이나 외경부(20)의 립(21)은 복수 개 구비되는 것이 바람직하다.In the present invention, it is preferable that the lip 11 of the inner diameter part 10 and the lip 21 of the outer diameter part 20 are provided in plurality.
