한편, 드럼(20)의 구성을 자세히 살펴보면, 드럼(20)은 개구부(13a)가 형성된 전면부(22)와, 구동모터(15)와 연결되는 후면부(23)와, 상기 전면부(22)와 후면부(23) 사이를 구성하는 원통부(21)를 포함한다.     On the other hand, looking at the configuration of the drum 20 in detail, the drum 20 has a front portion 22 having an opening 13a, a rear portion 23 connected to the drive motor 15, and the front portion 22 And a cylindrical portion 21 constituting between the rear portion 23.

따라서, 이러한 세 부분은 각각 가공과정을 거쳐 제작된 후에 다시 하나로 하는 접합과정을 거치게 된다.      Therefore, these three parts are each manufactured through a machining process and then subjected to a joining process.

이때 원통부(21)는 소정의 크기로 절단된 판재를 양쪽에서 말아서 원통형상이 되게 한 후 양단부를 중첩되게 접어서 용접하는 과정을 거쳐 제작된다.      At this time, the cylindrical portion 21 is made by rolling a plate cut to a predetermined size on both sides to have a cylindrical shape, and then folding and welding both ends to overlap each other.

따라서, 원통부(21)의 내주면에는 축방향과 평행하면서 길게 형성된 접합부(26)가 형성되며, 이 접합부(26)는 원통부(21)의 다른 내주면과 달리 오목한 홈(26a)과 이 홈을 중심으로 약간 돌출된 요철(26b)을 포함하게 된다.     Accordingly, the inner peripheral surface of the cylindrical portion 21 is formed with a joint 26 formed long in parallel with the axial direction, which is different from the other inner peripheral surface of the cylindrical portion 21 to concave the groove 26a and this groove. It will include a concave-convex (26b) slightly projected to the center.

드럼(20)내에 이러한 접합부(26)가 노출된 상태로 있게 되면, 세탁 및 탈수과정에서 세탁물과 접합부(26) 사이의 간섭현상이 발생되어 세탁물이 손상되게 되므로, 이를 방지하기 위하여 본 발명에 따른 드럼세탁기에 포함된 드럼은 접합부 (26)가 내주면으로 노출되는 것을 방지하기 위한 노출방지구조를 포함한다.      When the junction 26 is exposed in the drum 20, interference between the laundry and the junction 26 is generated during washing and dehydration, and thus the laundry is damaged, according to the present invention. The drum included in the drum washing machine includes an exposure preventing structure for preventing the joining portion 26 from being exposed to the inner circumferential surface.

상기 노출방지구조는 본 실시예에 따르면 원통부 내주면에 접합부(26)가 축방향과 평행하게 형성되고, 이 접합부(26) 위에 리프터(24)가 설치되어 접합부(26)를 리프터(24)가 가리도록 하는 구조이다.     According to the present embodiment, the exposure preventing structure has a junction portion 26 formed on the inner circumferential surface of the cylindrical portion parallel to the axial direction, and a lifter 24 is installed on the junction portion 26 so that the junction portion 26 is lifted by the lifter 24. It is a structure to hide.

즉, 드럼(20)내에 다수개가 원주방향으로 배치되는 리프터(24) 중 적어도 하나는 접합부(26) 상에 설치되는 것이다.     That is, at least one of the lifters 24 arranged in the circumferential direction in the drum 20 is provided on the joint portion 26.

접합부(26)에는 양단부의 두면이 만나는 지점에서 약간 오목하게 홈(26a)이 형성되고, 이 홈을 중심으로 요철(26b)이 형성되어 있는 경우, 리프터(24)가 원통부(21)의 내주면에 완전히 밀착되게 설치되지 않을 수 있다.      When the grooves 26a are slightly concave at the point where the two surfaces of both ends meet, and the concave-convex 26b is formed around the grooves, the lifter 24 is the inner circumferential surface of the cylindrical portion 21. May not be installed completely in contact with the

따라서, 리프터(24)와 내주면사이가 이격되는 것을 방지하기 위해 접합부(26)에 설치되는 리프터(24)에는 내주면과 조립되는 면에 접합부(26)가 수용될 수 있는 공간을 확보하기 위한 도피홈(24a)이 마련된다.    Therefore, the lifter 24 installed in the joint portion 26 to prevent the space between the lifter 24 and the inner circumferential surface is spaced apart to secure a space in which the joint portion 26 can be accommodated on the surface assembled with the inner circumferential surface. 24a is provided.

리프터(24) 내부가 빈 공간으로 형성할 경우에는 도시한 바와 같이 상기 도피홈(24a)은 리프터(24)의 양단부에 오목한 형상으로 마련된다.      When the inside of the lifter 24 is formed into an empty space, the escape groove 24a is provided in a concave shape at both ends of the lifter 24, as shown.

한편, 접합부(26) 위에 리프터(24)가 설치되어도 리프터(24) 내부로는 세탁수가 유입되고, 이에 따라 접합부(26)의 홈(26a)으로 린트가 축적될 수 있다.     On the other hand, even if the lifter 24 is installed on the junction 26, the wash water flows into the lifter 24, and thus lint may accumulate in the grooves 26a of the junction 26.

따라서, 접합부(26)의 홈(26a)으로 린트가 축적되는 것을 차단하기 위해 접합부에 실리콘과 같은 실링재로 마감처리한 후 리프터(24)를 설치할 수 도 있으며, 이 경우 실링재는 리프터(24)에 의해 보호되므로 훼손될 위험이 없게 된다.    Therefore, in order to prevent lint from accumulating in the grooves 26a of the junction part 26, the lifter 24 may be installed after finishing the sealing part with a sealing material such as silicon, in which case the sealant is attached to the lifter 24. Protected, so there is no risk of tampering.

Of course.

이하에는 본 발명에 따른 드럼세탁기의 동작과정 및 효과에 대하여 살펴본다.Hereinafter will be described the operation and effects of the drum washing machine according to the present invention.

도어(13)를 개방하여 세탁물을 드럼(20)에 넣은 상태에서 도어(20)를 닫고 세탁기의 동작을 개시하면 급수밸브(17)가 개방되면서 세탁을 위하여 필요한 물이 드럼(20)내로 공급된다.When the door 13 is opened and the laundry is put in the drum 20, the door 20 is closed and the washing machine starts to operate. The water supply valve 17 is opened, and water necessary for washing is supplied into the drum 20. .

일정수위가 되면 드럼(20)이 회전하면서 드럼(20)내부에서는 세탁이 시작되어 세탁물은 리프터(24)를 타고 드럼(20)내에서 상승하다가 아래로 낙하하는 동작을 반복하게 된다.     When the water level reaches a certain level, washing starts in the drum 20 while the drum 20 rotates, and the laundry is repeatedly lifted up in the drum 20 by the lifter 24 and then drops downward.

이때, 드럼(20)내의 원통부(21)에는 접합부(26)가 리프터(24) 아래에 있어 외부에 노출되지 않는 상태이므로 드럼(20) 내주면을 타고 움직이는 세탁물이 접합부(26)과 간섭현상을 일으키지 않게 되어 세탁과정 뿐만 아니라 탈수 및 건조과정에서의 세탁물의 손상이 방지된다.      At this time, since the junction portion 26 is below the lifter 24 in the cylindrical portion 21 of the drum 20 and is not exposed to the outside, the laundry moving on the inner circumferential surface of the drum 20 interferes with the junction portion 26. It does not cause damage to the laundry during dehydration and drying as well as during the washing process.

나아가, 접합부(26)를 별도의 실링재로 마감처리할 경우, 접합부(26)에 린트가 축적되어 세균이 증식하는 현상이 방지된다.    Furthermore, when the joint 26 is finished with a separate sealing material, lint is accumulated in the joint 26 to prevent the growth of bacteria.

이상에서 살펴본 바와 같이, 본 발명에 따른 드럼세탁기는 드럼의 제작과정에서 생기는 접합부가 리프터에 의해 가려져 드럼내부로 노출되지 않는 구조이므로 접합부에 의한 세탁물의 간섭현상이 없어져 접합부에 의한 세탁물의 손상이 방지된 다.As described above, the drum washing machine according to the present invention has a structure in which the joint generated in the drum manufacturing process is covered by the lifter and is not exposed to the drum, thereby eliminating interference of the laundry by the joint, thereby preventing damage to the laundry by the joint. do.

나아가, 접합부를 실링재로 마감할 경우 접합부의 홈에 린트가 축적되는 것이 방지되어 드럼내의 세균증식이 억제되는 효과가 있다.Furthermore, when the joint is finished with a sealing material, lint is prevented from accumulating in the groove of the joint, thereby suppressing bacterial growth in the drum.
