본 고안은 드럼세탁기의 중심추 고정장치에 관한 것으로서, 더욱 상세하게는 간단한 구조에 의해 중심추가 커버브라켓에 고정되도록 하여 원가가 절감되도록 함과 함께 조립작업성이 향상되도록 한 것이다.The present invention relates to a central weight fixing device of a drum washing machine, and more particularly, to improve the assembly workability while reducing the cost by being fixed to the center cover cover bracket by a simple structure.

일반적으로 드럼세탁기는 본체(1) 내부로 한쌍의 댐퍼(2)와 스프링(3)에 의해 터브(4)가 지지되어 있고, 상기 터브의 외측둘레면 후방에는 구동력을 발생시키도록 모터(5)가 부착되어 있으며, 상기 터브 내에는 모터(5)의 구동력을 벨트(6)를 통해 전달받아 회전되도록 드럼(7)이 설치되어 있으며, 상기 터브(4)의 전면에는 터브의 무게중심에 따른 전,후방 균형을 유지하여 주도록 중심추(8)가 고정장치에 의해 고정되어 있다.In general, the drum washing machine is supported by the tub (4) by a pair of dampers (2) and the spring (3) into the main body 1, the motor (5) to generate a driving force behind the outer peripheral surface of the tub (5) The tub 7 is installed in the tub so that the driving force of the motor 5 is transmitted through the belt 6 and rotated, and the front of the tub 4 is moved according to the center of gravity of the tub. The center weight 8 is fixed by the fixing device to maintain the rear balance.

따라서, 본체(1)의 전면에 설치된 도어(도시는 생략함)를 열어 터브(4) 내에 설치된 드럼(7) 내부로 세탁물과 함께 세제를 투입한 다음 다시 도어를 닫고 세탁시작버튼을 선택하면 급수수단에 의해 세탁에 사용될 물이 상기 터브(4) 내로 들어가 터브와 드럼(7)에 채워지는데, 이때 터브(4) 내에 설치된 수위센서가 터브에 채워지는 물의 수위를 감지하여 적정수위가 되면 마이콤으로 신호를 보내게 되고 상기 마이콤은 이 신호를 받아 급수수단에 의한 세탁수의 공급을 중단시킨다.Therefore, open the door (not shown) installed on the front of the main body 1, put detergent into the drum (7) installed in the tub (4) and then close the door again and select the start washing button The water to be used for washing by the means enters the tub 4 and is filled in the tub and the drum 7, wherein the water level sensor installed in the tub 4 detects the water level of the water filled in the tub and returns to the microcomputer when the proper level is reached. The microcomputer receives the signal and stops the supply of the wash water by the water supply means.

상기한 작용에 의해 드럼(7)이 회전하면 수류가 일어남과 함께 상기 드럼의 내측둘레면에 고정된 복수개의 리프트(도시는 생략함)가 계속적으로 드럼(7) 내의 세탁물을 끌고 올라가서 떨어뜨려 주므로 세탁물이 드럼과의 마찰력, 세제와의 분해력등에 의해 세탁된다.When the drum 7 rotates by the above-described action, water flow occurs and a plurality of lifts (not shown) fixed to the inner circumferential surface of the drum continually drag the laundry in the drum 7 and drop it off. The laundry is washed by the friction force with the drum and the decomposition force with the detergent.

한편 세탁행정이 완료되면 배수수단이 마이콤의 제어에 의해 작동되므로 세탁에 사용되었던 물이 외부로 배출되고 상기 터브 내의 물이 완전히 배출 완료되면 계속해서 헹굼행정과 탈수행정이 행하여지므로 세탁물의 세탁이 완료된다.On the other hand, when the washing stroke is completed, the drainage means is operated by the control of the microcomputer, so that the water used for washing is discharged to the outside, and when the water in the tub is completely discharged, the rinsing stroke and the dehydration stroke are continuously performed. .

이와같은 작용에 의해 세탁이 행하여 질 때 드럼(7)의 회전에 따라 진동이 발생하는데, 이때 터브(4)가 한쌍의 댐퍼(2)와 스프링(3)에 의해 지지되어 있으므로 상기 드럼(7)의 회전에 따른 진동력이 일부분 상쇠됨은 이해 가능하다.When washing is performed by such an operation, vibration occurs as the drum 7 rotates. At this time, the tub 4 is supported by the pair of dampers 2 and the spring 3, so that the drum 7 It is understood that the vibration force due to the rotation of the part partially cancels.

또한 터브(4)의 전방에 중심추(8)가 고정장치에 의해 고정되어 상기 터브(4)의 후방으로 모터(5)가 부착되어 있음에 따른 전,후방 균형을 유지하여 주고 있는데, 이는 터브(4)의 무게중심이 한쪽으로 쏠릴 경우 드럼(7)이 회전할 때 큰 진동력이 발생되므로 이를 미연에 방지하고자 하기 위함이다.In addition, the center weight 8 is fixed to the front of the tub 4 by the fixing device to maintain the front and rear balance as the motor 5 is attached to the rear of the tub 4, which is the tub If the center of gravity of (4) is directed to one side, a large vibration force is generated when the drum 7 rotates to prevent this in advance.

이상에서 설명된 바와같은 드럼세탁기의 종래 중심추 고정장치는 터브(4)의 전면에 고정된 터브커버(9)와, 상기 터브커버에 고정되어 중심부로 사각구멍(10a)이 일체 형성된 복수개의 커버브라켓(10)과, 상기 커버브라켓의 사각구멍(10a)에 코킹되어 나사구멍을 갖는 특수너트(11)와, 상기 각 특수너트의 나사공에 나사결합되어 중심추(8)를 고정하는 고정볼트(12)로 구성되어 있다.Conventional center weight fixing device of the drum washing machine as described above is a tub cover (9) fixed to the front of the tub (4), a plurality of covers fixed to the tub cover, the square hole (10a) integrally formed in the center A special nut 11 which is screwed into the bracket 10, the square hole 10a of the cover bracket and has a screw hole, and a fixing bolt which is screwed into the screw hole of each special nut to fix the center weight 8 It consists of 12.
