The present invention relates to a drum washing machine in which the number is reduced, debris is prevented from sticking to the drum, and the emotional quality is improved.

드럼세탁기는 원통형의 드럼내에 리프터를 설치하여, 세제 및 세탁수를 포함하고 있는 드럼내부의 세탁물이 드럼이 회전함에 따라 리프터에 의해 들여올려지면서 이때 발생되는 낙차, 즉 위치에너지에 의해 세탁물에 세탁을 위한 에너지를 가하여 세탁이 이루어지는 방식이다.The drum washing machine installs a lifter in a cylindrical drum so that laundry inside the drum containing detergent and washing water is lifted by the lifter as the drum rotates, thereby washing the laundry due to a drop, ie, potential energy. Washing is performed by applying energy for

도 1은 일반적인 드럼세탁기의 구조를 나타낸 수직 측단면으로써, 상기 도면을 참조하여 종래의 일반적인 드럼세탁기의 드럼의 구조를 설명한다.Figure 1 is a vertical side cross-sectional view showing the structure of a conventional drum washing machine, with reference to the drawings will be described the structure of a drum of a conventional drum washing machine.

드럼세탁기의 외관을 형성하는 케이싱(10) 내부에는 원통형의 터브(11)가 설치되고, 드럼(12)이 상기 터브(11)내에서 그 회전축(13)이 드럼세탁기가 설치되는 바닥면에 평행하도록 눕혀진 상태로 설치된다.A cylindrical tub 11 is installed inside the casing 10 that forms the drum washing machine, and the drum 12 is parallel to the bottom surface on which the rotating shaft 13 is installed in the tub 11. It is installed so that it is laid down.

상기 드럼(12)은 회전축(13)이 구동부(14)와 연결되어 상기 터브(11)내에 회전가능하게 설치되고, 내면에는 리프트(15)가 소정간격 이격되어 축방향으로 배열 설치된다.The drum 12 has a rotation shaft 13 connected to the driving unit 14 so as to be rotatable in the tub 11, and the lift 15 is arranged in the axial direction at a predetermined interval on the inner surface thereof.

그러나, 종래의 드럼세탁기의 드럼은 제작공정에 있어 투입구(16)가 형성된 원반형상의 전면부(12a), 드럼의 외주면 및 내주면을 이루는 원통부(12b) 및 구동부(14)와 연결되는 후면부(12c)가 각각 가공되고, 가공된 각부분을 심용접(seam welding) 또는 컬링(curling) 가공 등에 의해 결합하는 방법으로 제작되었다.However, the drum of the conventional drum washing machine has a disk-shaped front portion 12a having an inlet 16 formed therein, a cylindrical portion 12b constituting the outer and inner circumferential surfaces of the drum, and a rear portion 12c connected to the driving portion 14. ) Were processed, and the fabricated parts were joined by seam welding or curling.

이러한 제작방법의 경우, 첫째로 용접이나 컬링공정으로 인해 공정수가 증가되는 문제가 있으며, 결합되는 결합부에 결합가공에 따른 불규칙한 부분이 발생될 수 있는데, 이러한 불규칙한 가공면에 의해 세탁물이 손상될 수 있고 가공면을 다듬는 과정을 행할 경우 추가공정에 의한 생산원가의 증가가 불가피하다.In the case of such a manufacturing method, first, there is a problem that the number of processes due to the welding or curling process is increased, and irregular portions may be generated due to the joining process to the joining portion to be joined, and the laundry may be damaged by the irregular processing surface. In addition, the process of trimming the processed surface is inevitable to increase the production cost by the additional process.

둘째로, 드럼 내부에는 전면과 후면의 결합부에 갭라인이 형성되는데, 이러한 갭라인부분에서 강도가 저하될 수 있으며 세탁물에 의해 생성되는 린트(lint)가 축적될 수 있고, 이로 인해 드럼내에 세균과 곰팡이가 증식하기 좋은 환경을 제공하며, 나아가 드럼의 부식을 초래할 수 있는 문제가 있다.Secondly, a gap line is formed inside the drum at the joining portion of the front and rear surfaces, whereby the strength may be degraded at the gap line portion, and lint generated by the laundry may accumulate, thereby causing bacteria in the drum. It provides a good environment for the growth of mold and fungi, and furthermore there is a problem that can lead to corrosion of the drum.

셋째로, 드럼세탁기의 전면에 설치되는 도어를 통해 드럼내부에 형성된 갭라인을 소비자가 볼 수 있으므로 소비자 감성품질을 떨어뜨리는 문제가 있었다. Third, the consumer can see the gap line formed inside the drum through the door installed in the front of the drum washing machine, there was a problem of lowering consumer emotional quality.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 딥 드로잉 가공에 의해 드럼의 원통부와 후면부를 일체로 형성하여 드럼의 강도 및 생산성이 향상되고 갭라인의 존재로 인해 생기는 문제점이 해결되는 드럼세탁기를 제공하는 것이다.The present invention is to solve such a problem, by providing a drum washing machine in which the cylindrical portion and the rear portion of the drum is integrally formed by deep drawing processing to improve the strength and productivity of the drum and the problem caused by the presence of the gap line is solved.

이하에는 본 발명에 따른 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

전면에 투입구가 형성된 케이스(20) 내에 터브(21)가 설치되고, 상기 터브(21)내에는 드럼(22)이 회전가능하게 설치되고, 드럼의 회전축(23)은 구동부(24)와 연결되어 구동부(24)의 회전력에 의해 드럼(22)이 회전하게 된다.A tub 21 is installed in a case 20 having an inlet formed in the front surface thereof, and a drum 22 is rotatably installed in the tub 21, and a rotating shaft 23 of the drum is connected to the driving unit 24. The drum 22 rotates by the rotational force of the driving unit 24.

드럼(22)의 내면에 설치된 리프터(25)는 회전축과 평행하게 배열되어 설치되는데, 리프터(25)를 설치를 위해 드럼(22)내에는 설치홈(28)이 형성될 수 있으며 설치홈(28)은 딥드로잉 가공에 의해 상기 일체부(22b)의 후면부분에 형성됨이 바람직하다.The lifter 25 installed on the inner surface of the drum 22 is installed to be arranged in parallel with the rotation axis, the installation groove 28 may be formed in the drum 22 for installing the lifter 25 and the installation groove 28 ) Is preferably formed on the rear portion of the integral portion 22b by deep drawing.

드럼(22)에는 세탁과정 이후에 진행되는 헹굼 및 탈수과정에서 세탁수가 배출되도록 다수개의 탈수공(27)이 드럼(22)내면에 고루 분포하도록 형성된다. The drum 22 is formed so that a plurality of dehydration holes 27 are evenly distributed on the inner surface of the drum 22 so that the washing water is discharged in the rinsing and dehydration process performed after the washing process.

드럼세탁기의 세탁과정을 설명하면, 투입구(26)를 통해 세탁물과 함께 드럼(22)내로 세제와 물을 투입하고 구동부(24)가 작동되어 드럼(22)이 회전하면 세탁물은 리프터(25)를 따라 상승하다가 다시 낙하하게 되는데, 이때 낙차에 의한 위치에너지에 의해 세탁물에 충격이 가해지면서 세탁이 이루어지게 된다.Referring to the washing process of the drum washing machine, the detergent and water are introduced into the drum 22 together with the laundry through the inlet 26 and the driving unit 24 is operated so that the laundry rotates the lifter 25. As it rises and falls again, the impact is applied to the laundry by the potential energy caused by the drop, and the washing is performed.

도 3을 참조하면, 본 발명에 의한 드럼세탁기의 드럼(22)은 투입구(26)측의 전면부(22a)와, 원통부분과 회전축(23)이 연결되는 후면부분을 포함하는 일체부(22b)를 포함하는 두 개의 바디로 구성된다.3, the drum 22 of the drum washing machine according to the present invention includes an integrated portion 22b including a front portion 22a on the inlet 26 side, and a rear portion to which the cylindrical portion and the rotating shaft 23 are connected. It consists of two bodies containing).

일체부(22b)는 딥 드로잉 성형에 의해 일체로 가공되고, 투입구(26)가 형성된 전면부(22a)는 별도로 성형되어 용접 또는 컬링공정에 의해 결합되어 드럼(22)이 형성된다.The integral part 22b is integrally processed by deep drawing molding, and the front part 22a on which the inlet 26 is formed is separately molded and joined by a welding or curling process to form a drum 22.

따라서, 드럼(22)의 후면부분과 원통부분사이에는 갭라인이 존재하지 않고, 전면부(22a)와 일체부(22b)사이에서만 갭라인이 존재하게 된다.Therefore, no gap line exists between the rear portion and the cylindrical portion of the drum 22, and the gap line exists only between the front portion 22a and the integral portion 22b.

딥드로잉에 의해 일체부(22b)가 가공되므로 탈수공(27) 및 기타 다른 구조물을 설치하기 위한 설치공(미도시)을 형성하는 커팅공정은 딥 드로잉에 의해 일체부(22b)를 성형한 다음에 이루어짐이 바람직하다.Since the integral part 22b is processed by deep drawing, the cutting process of forming an installation hole (not shown) for installing the dehydration hole 27 and other structures is performed by forming the integral part 22b by deep drawing. It is preferable to

이와같은 드럼(22)의 제작공정은 세개의 바디로 이루어지는 드럼에 비해서 원통부분을 제작할 때 판상의 재료를 말아 양단부를 심용접에 의해 원통형으로 제작하고, 다시 후면부를 컬링 등에 의해 결합하는 공정이 딥드로잉에 의해 한번에 이루어지므로 공정수가 감소된다.The manufacturing process of such a drum 22 is a process of rolling a plate-like material into a cylindrical shape by seam welding, and joining the rear part by curling, etc., when manufacturing a cylindrical portion, compared to a drum consisting of three bodies. Since the drawing is done in one step, the number of processes is reduced.

이러한 제작공정의 감소이외에, 회전축과 결합되는 후면부분과 원통부분사이 에 갭라인이 존재하지 않으므로 드럼의 강성확보가 가능해지고, 또한 투입구를 통해 비춰지는 드럼의 내부에 갭라인이 관찰되지 않으므로 소비자의 감성품질이 향상된다.In addition to the reduction of the manufacturing process, there is no gap line between the rear portion and the cylindrical portion coupled with the rotating shaft, thereby ensuring the rigidity of the drum, and also because the gap line is not observed inside the drum projected through the inlet, Emotional quality is improved.

또한, 갭라인에 이물질이 끼고 곰팡이 또는 세균이 증식하는 현상이 감소된다. In addition, the phenomenon in which foreign matter is caught in the gap line and the growth of mold or bacteria is reduced.

본 발명은 상술한 바와 같이, 드럼이 딥드로잉에 의해 일체로 구성되는 일체부를 포함하므로 제작공정수가 감소될 뿐만 아니라, 드럼의 강성보강면에서도 유리하고 아울러 후면쪽의 갭라인 생략되므로 이물질에 의한 영향이 감소되고 외관형성에 있어서도 유리하다.As described above, since the drum includes an integral part integrally formed by deep drawing, the number of manufacturing processes is not only reduced, but also advantageous in the rigidity reinforcement surface of the drum, and the gap line on the rear side is omitted, and thus the influence of foreign matter. This is reduced and also advantageous in appearance appearance.
