종래에 일반적으로 사용되어온 드럼세탁기는 첨부도면 제4도에 도시된 바와같이 상면과 전면에 균형추(41)가 고정된 세탁조(42)내에 설치되어 있는 드럼(43)의 후면에 스파이더(spider)(44)가 고정되어 있고, 상기 스파이더(44)에 드럼축(45)이 고정되어 있으며, 드럼축(45)은 베어링 하우징(46)내에 설치된 2개의 베어링에 의해 지지되어 있다.Drum washing machines generally used in the prior art as shown in Figure 4 attached to the spider (spider) on the rear of the drum 43 is installed in the washing tank 42, the balance weight 41 is fixed to the top and front as shown in FIG. 44 is fixed, the drum shaft 45 is fixed to the spider 44, and the drum shaft 45 is supported by two bearings provided in the bearing housing 46.
드럼축(45)의 후단부에는 드럼풀리(47)가 고정되어 있고, 이 드럼풀리(47)는 세탁조(42)의 밑면에 고정된 모터(48)의 풀리(49)와 벨트(50)로 연결되어 모터(48)의 구동력에 의해 회전하며, 상기한 진동부는 4개의 댐퍼(51)에 의해 밑판에 지지되어 있다.A drum pulley 47 is fixed to the rear end of the drum shaft 45, and the drum pulley 47 is formed by the pulley 49 and the belt 50 of the motor 48 fixed to the bottom of the washing tub 42. It is connected and rotated by the driving force of the motor 48, the vibration portion is supported on the bottom plate by four dampers (51).
또한, 뒷판에 설치된 급수구(55)는 세탁조(42)와 연결되어 있고, 배수구(52)는 배수펌프(53)와 연결되어 있으며 세탁물 투입구인 도어(54)와 세탁조(42) 사이에는 도어 벨로우즈(56)가 설치되어 있다.In addition, the water supply port 55 installed on the back plate is connected to the washing tank 42, the drain port 52 is connected to the drain pump 53, the door bellows between the door 54 and the washing tank 42, which is the laundry inlet 56 is provided.
따라서, 모터(48)에 전원이 공급되면 그 구동력이 풀리(49), 벨트(50), 드럼풀리(47), 드럼축(45), 스파이더(44)를 통해 드럼(43)에 전달되어 드럼(43)이 회전하게 되고 세탁물은 드럼(43)과 함께 회전을 하면서 세탁 또는 탈수작용이 이루어지며, 세탁수는 배수펌프(53)의 구동에 의해 배수구로 배수된다.Therefore, when power is supplied to the motor 48, the driving force is transmitted to the drum 43 through the pulley 49, the belt 50, the drum pulley 47, the drum shaft 45, and the spider 44, and thus the drum. The 43 is rotated and the laundry is rotated together with the drum 43 to perform washing or dehydration, and the washing water is drained to the drain by the driving of the drain pump 53.

제1도는 본 고안 세탁기의 구동부 사시도이고, 제2도는 본 고안 세탁기의 탈수시 세탁조가 세워진 상태의 종단면도이며, 제3도는 본 고안 세탁기의 세탁시 세탁조가 눕혀진 상태의 종단면도로서, 투명카바(15)를 갖는 세탁기의 케이스(1)내에 세탁조(2)를 설치하여, 세탁조(2)의 일측과 타측 둘레면에 각각 한쌍의 보스(16)(16a)를 형성하고 상기 일측보스(16)에 베어링축(17)을 고정함과 함께 타측보스(16a)에는 기어축(18)을 갖는 고정판(19)을 고정하여 일측의 베어링축(17)과 타측의 기어축(18)에 댐퍼(11)에 의해 지지되는 베어링하우징(21)을 설치한다.1 is a perspective view of a driving unit of the washing machine of the present invention, Figure 2 is a longitudinal cross-sectional view of the washing tank is standing up when dehydration of the washing machine of the present invention, Figure 3 is a longitudinal cross-sectional view of the washing tank lying down when washing the washing machine of the present invention, transparent cover The washing tank 2 is provided in the case 1 of the washing machine having the 15, and a pair of bosses 16 and 16a are formed on one side and the other circumferential surface of the washing tank 2, respectively. The bearing shaft 17 is fixed to the other side, and the fixing plate 19 having the gear shaft 18 is fixed to the other boss 16a, thereby damping the damper 11 to the bearing shaft 17 on one side and the gear shaft 18 on the other side. The bearing housing 21 supported by) is installed.
또한, 타측의 기어축(18)에 마이크로스위치(22)(22a)가 부착된 워엄기어(23)를 고정하여 모터브라켓(24)에 장착된 스텝모터(25)의 워엄(26)과 맞물릴 수 있도록 하고, 베어링하우징(21)에 리미트바(27)를 고정하여 상기 리미트바(27)와 모터브라켓(24)에 마이크로스위치(22)(22a)가 각각 접속될 수 있게 한다.In addition, the worm gear 23 with the microswitches 22 and 22a is fixed to the gear shaft 18 on the other side to engage with the worm 26 of the step motor 25 mounted on the motor bracket 24. And the limit bar 27 is fixed to the bearing housing 21 so that the micro switches 22 and 22a may be connected to the limit bar 27 and the motor bracket 24, respectively.
그리고 급수구(28)을 베어링축(17)내로 삽입하여 패킹(29)에 의해 회전가능하도록 한 것으로 미설명부호 30은 카버이다.In addition, the water inlet 28 is inserted into the bearing shaft 17 so as to be rotatable by the packing 29. Reference numeral 30 denotes a cover.
이와 같이 구성된 본 고안은 세탁시 첨부도면 제2도와 같이 세탁조(2)가 세워진 상태에서 카버(30)를 연다음 도어(14)를 열고 드럼(3)내로 세탁물을 넣는다.The present invention configured as described above opens the carver 30 in the washing tank 2 in a standing state as shown in FIG. 2 attached to the laundry, and then opens the door 14 and puts the laundry into the drum 3.
세탁이 투입이 완료되면 도어(14)와 카버(30)을 닫고 콘트롤러의 스위치를 동작시키면 되는데, 스위치를 동작시키면 세탁조(2)가 베어링하우징(21)을 축으로 하여 90° 회전하므로 첨부도면 제3도와 같이 세탁조(2)가 눕혀지게 된다.When the washing is completed, the door 14 and the carver 30 are closed and the controller is operated. When the switch is operated, the washing tank 2 rotates 90 ° around the bearing housing 21, so The washing tank 2 is laid down as shown in FIG.
즉, 스텝모터(25)에 전원이 공급되어 스텝모터(25)가 정회전하면 스텝모터(25)축에 고정된 워엄(26)과 워엄(26)에 맞물린 워엄기어(23)가 회전하므로 워엄기어(23)가 고정된 기어축(18)도 함께 회전하게 된다.That is, when power is supplied to the step motor 25 and the step motor 25 rotates forward, the worm 26 fixed to the shaft of the step motor 25 and the worm gear 23 engaged with the worm 26 rotate so that the worm is rotated. The gear shaft 18 to which the gear 23 is fixed also rotates.
그러므로 기어축(18)을 갖는 고정판(19)이 세탁조(2)와 일체로 형성된 보스(16a)에 고정되어 있으므로 세탁조(2)가 베어링하우징(21)을 축으로 하여 회전되어 눕혀지는 것이다.Therefore, since the fixing plate 19 having the gear shaft 18 is fixed to the boss 16a integrally formed with the washing tank 2, the washing tank 2 is rotated and laid down on the bearing housing 21 as the axis.
이때, 워엄기어(23)에 고정된 마이크로스위치(22)도 회전되고 상기 마이크로스위치(22)가 모터브라켓(24)에 부딪치게 되므로 스텝모터(25)의 전원을 차단시켜서 스텝모터(25)는 정지한다.At this time, the micro switch 22 fixed to the worm gear 23 is also rotated and the micro switch 22 hits the motor bracket 24 so that the step motor 25 is turned off by shutting off the power of the step motor 25. do.
상기와 같이하여 세탁조(2)가 눕혀지면 종래 세탁기와 동일한 작용으로 하여 세탁과 헹굼동작을 실시하고, 세탁과 헹굼동작이 완료되면 세탁조(2)를 바로 세워서 탈수를 하여야 하는데 이때에는 스텝모터(25)를 역회전 시키면 된다.When the washing tank 2 is laid as described above, the washing and rinsing operations are performed in the same manner as the conventional washing machine, and when the washing and rinsing operations are completed, the washing tank 2 should be upright and dehydrated. In this case, the step motor 25 ) To reverse.
스텝모터(25)를 역회전시키면 워엄(26)과 워엄기어(23)가 역회전되고, 워엄기어(23)가 역회전할때 워엄기어(23)에 고정된 마이크로스위치(22a)가 베어링하우징(21)에 고정된 리미트바(27)에 접속하게 되므로 역회전하는 스텝모터(25)를 정지시킨다.When the step motor 25 is rotated in reverse, the worm 26 and the worm gear 23 are rotated in reverse, and when the worm gear 23 is rotated in reverse, the micro switch 22a fixed to the worm gear 23 is bearing housing. Since it connects to the limit bar 27 fixed to 21, the step motor 25 which reversely rotates is stopped.
이와 같은 동작으로 세탁조(2)가 세워지면 모터(8)가 고속회전하여 탈수를 하면 되는 것으로 세탁조(2)가 세워지거나 눕혀지더라도 급수구(28)는 베어링축(17)내에 패킹(29)에 의해 체결되어 회전하므로 세탁조(2)의 회전시 간섭이 없게 되는 것이다.When the washing tank 2 is erected in this manner, the motor 8 rotates at a high speed to dehydrate the water supply port 28 in the bearing shaft 17 even if the washing tank 2 is standing or lying down. It is fastened by the rotation so that there is no interference during the rotation of the washing tank (2).
그러므로 세탁조(2)가 수직으로 세워진 상태에서 탈수를 하게 되면 옆으로 눕혀서 탈수할 때보다 세탁물이 드럼(3)에 골고루 분산되므로 진동 및 소음이 줄어들게 되고 종래, 드럼세탁기의 세탁조에 부착된 균형추를 부착하지 않아도 되어 제품의 무게를 줄일 수 있는 효과가 있다.Therefore, if the washing tank 2 is dehydrated in a vertical position, the laundry is distributed evenly on the drum 3 rather than lying on the side, so vibration and noise are reduced. Conventionally, a counterweight attached to the washing machine of the drum washing machine is attached. There is no need to reduce the weight of the product.
