드럼 세탁기용 드럼과 샤프트 플랜지 체결구조Drum and shaft flange fastening structure for drum washing machine

본 발명은 드럼 세탁기용 드럼과 샤프트 플랜지 체결구조에 관한 것으로서, 더욱 상세하게는 드럼 세탁기의 드럼과 드럼의 후방에 구동부와 연결되는 샤프트 플랜지를 용이하게 체결시킬수 있도록 한 것이다.The present invention relates to a drum and shaft flange fastening structure for a drum washing machine, and more particularly, to facilitate fastening of a shaft flange connected to a driving part at a rear of a drum and a drum of the drum washing machine.

일반적으로, 드럼의 회전으로 발생된 낙차에 의해 세탁되는 드럼 세탁기는 세탁, 헹굼, 탈수, 건조가 자동으로 이루어지는 세탁 및 건조 일체형과, 건조 기능이 생략된 세탁 단독형의 세탁기가 있는데, 종래의 도 1과 같은 드럼 세탁기에서 세탁시에는 터브(9)내의 드럼(1a)의 회전으로 발생된 낙차를 이용하여 두드려 빠는 방식으로 세탁을 진행하게 된다.In general, a drum washing machine that is washed by a drop generated by rotation of a drum includes a washing and drying integrated type in which washing, rinsing, dehydration, and drying are automatically performed, and a washing type washing machine in which a drying function is omitted. When washing in a drum washing machine as shown in 1, washing is performed by tapping and sucking using a drop generated by the rotation of the drum 1a in the tub 9.

또한, 세탁이 완료된 세탁물을 건조시, 터브(9)의 내부로 도관을 통해 들어오는 건조한 공기는 세탁물의 수분을 흡수한 수증기로 변화하게 됨과 동시에, 원심팬의 작동에 의해 건조 히터로 이동중에 상기 터브(9)의 벽면에 콘덴싱 호스로부터 공급된 소량의 냉수에 의해 응축되어 1500W의 건조 히터에 옮겨지게 되며, 물은 배수구를 통해 배수 호스로 배출된다.In addition, when the laundry is dried, the dry air entering through the conduit into the tub 9 is changed to water vapor absorbing the moisture of the laundry, while the tub while moving to the drying heater by the operation of the centrifugal fan. The wall surface of (9) is condensed by a small amount of cold water supplied from the condensing hose and transferred to a 1500W dry heater, and the water is discharged through the drain hole to the drain hose.

또한, 수송된 공기는 다시 건조 히터에 의해 가열되고 난 후 도관을 통해 드럼(3)의 내부로 들어가는 이와같은 과정을 반복 진행하므로써 건조가 진행되고, 완전 건조행정이 진행되는 동안 응축된 물의 배수를 하기 위해 배수 펌프는 30초 정지, 5초 작동의 방식으로 간헐적으로 작동된다.In addition, the transported air is heated again by the drying heater, and then the drying process is repeated by repeatedly entering the inside of the drum 3 through the conduit and draining the condensed water during the complete drying process. The drain pump is operated intermittently in the manner of a 30 second stop, a 5 second operation.

또한, 도 1에 나타낸 바와같이 터브(9)의 내부에는 회전가능하게 드럼(1a)이 설치되고, 터브(9)내의 드럼(1a) 전,후방에는 복수개의 볼(Steel Ball)(10)이 내장된 볼 밸런서(11)가 설치되어 세탁물이 한쪽으로 몰려 진동과 소음이 발생되기 전에 균형을 잡아 주어 진동과 소음을 줄여 주게 되며, 상기 드럼(9)의 전체면에는 물이 통과하기 위한 복수개의 미세한 통공(도시는 생략함)이 형성되고, 상기 터브(9)의 후방에는 알루미늄재로 다이캐스팅된 후면 커버(12)가 장착되며, 상기 터브(9) 내의 드럼(1a) 내부에는 드럼(1a)의 회전시 세탁물을 들어 올려주기 위한 복수개의 몰드물로 된 리프터(2)가 체결된다.In addition, as shown in FIG. 1, the drum 1a is rotatably installed inside the tub 9, and a plurality of steel balls 10 are disposed before and behind the drum 1a in the tub 9. Built-in ball balancer (11) is installed to balance the laundry before the vibration and noise generated to one side to reduce the vibration and noise, the entire surface of the drum (9) a plurality of passages for water to pass through A fine through hole (not shown) is formed, and a rear cover 12 die-cast with aluminum is mounted on the rear of the tub 9, and a drum 1a inside the drum 1a in the tub 9. The lifter 2 is formed of a plurality of molds for lifting the laundry during the rotation of.

한편, 드럼(1a)과 드럼(1a)의 후방에 구동부와 연결되는 샤프트 플랜지(6)를 체결시에는 리프터(2)의 변형을 방지하기 위해 내부의 전체 구간에 걸쳐 알루미늄재로 된 지지 부재(3a)를 삽입시킨 상태에서 장볼트(5a)가 상기 드럼(1a)의 전면을 관통하여 드럼(1a) 후면의 샤프트 플랜지(6)에 너트(13)로서 체결되며, 드럼(1a)의 전면 상부에는 지지 부재(3a)가 리프터(2)의 내부에서 유동되는 것을 방지하기 위해 드럼(1a)의 수직 방향으로 볼트(7)가 체결된다.On the other hand, when fastening the shaft flange 6 connected to the driving part at the rear of the drum 1a and the drum 1a, a support member made of aluminum material over the entire section of the inside to prevent deformation of the lifter 2 ( A long bolt 5a penetrates the front surface of the drum 1a with 3a) inserted therein and is fastened as a nut 13 to the shaft flange 6 at the rear of the drum 1a, and the upper front of the drum 1a. The bolt 7 is fastened in the vertical direction of the drum 1a to prevent the support member 3a from flowing inside the lifter 2.

그러나, 이와같은 종래의 드럼(1a)과 드럼(1a)의 후방에 구동부와 연결되는 샤프트 플랜지(6)를 체결시에는 드럼(1a)의 전면에서부터 장볼트(5a)를 끼워 샤프트 플랜지(6)의 후면에서 너트(13)로 체결시켜야 하므로 인해 체결 공정이 복잡하여 생산성이 떨어지게 되고, 장볼트(5a)를 끼울 때 많은 불편함이 따르게 되며, 드럼(1a)의 중량이 무거워지게 되고, 상기 몰드물로 된 리프터(2)의 내부에 리프터(2)의 변형 방지를 위한 알루미늄재로 된 지지 부재(3a)를 내부의 전 구간에 걸쳐 삽입시켜서 체결시켜야 하므로 인해 제작 단가가 상승하게 되는 등의 많은 문제점이 있었다.However, when fastening the shaft flange 6 connected with the driving unit to the rear of the conventional drum 1a and the drum 1a, the long flange 5a is inserted from the front of the drum 1a and the shaft flange 6 Since the fastening process is complicated because the fastening process has to be tightened with the nut 13 at the rear of the product, the productivity is lowered, and when the long bolts 5a are inserted, a lot of inconvenience follows, the weight of the drum 1a becomes heavy, and the mold Since the support member 3a made of aluminum material for preventing deformation of the lifter 2 must be inserted into the inside of the lifter 2 made of water and fastened over the entire section, the manufacturing cost increases. There was a problem.

본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 드럼 세탁기의 드럼과 드럼의 후방에 구동부와 연결되는 샤프트 플랜지를 용이하고 견고한 상태로 체결시킬수 있도록 하여 체결 공정의 단순화에 따른 생산성을 향상시킬수 있을 뿐만 아니라 비용이 저렴한 부품을 사용하여 제작 단가를 절감시킬수 있는 드럼 세탁기용 드럼과 샤프트 플랜지 체결구조를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, it is possible to fasten the shaft flange connected to the driving unit on the rear of the drum and the drum of the drum washing machine in an easy and solid state can not only improve the productivity according to the simplification of the fastening process In addition, the purpose is to provide a drum washing machine drum and shaft flange fastening structure that can reduce the production cost by using low-cost components.
