Description

전자동 세탁기{AUTOMATIC WASHING MACHINE}Fully automatic washing machine {AUTOMATIC WASHING MACHINE}

본 발명은 전자동 세탁기에 관한 것으로, 특히 세탁시 펄세이터가 상,하로 움직이며 세탁물을 쳐주면서 세탁이 이루어지도록 하여 효율적인 세탁이 이루어질 수 있도록 한 전자동 세탁기에 관한 것이다.The present invention relates to a fully automatic washing machine, and more particularly, to a fully automatic washing machine in which the washing is performed while the pulsator moves up and down while washing the laundry.

종래의 전자동 세탁기의 내부구조가 도 1에 도시되어 있는 바, 이를 간단히 설명하면 다음과 같다.The internal structure of a conventional fully automatic washing machine is shown in FIG. 1, which will be described briefly as follows.

도시된 바와 같이, 종래의 전자동 세탁기는 세탁수가 담겨지는 외조(1)의 내측에 세탁물이 담겨지는 내조(2)가 회전가능하게 설치되어 있고, 그 내조(2)의 내부 저면에는 수류를 형성하기 위한 펄세이터(3)가 회전가능하게 결합되어 있다.As shown, the conventional fully automatic washing machine is rotatably installed in the inner tank (2) in which the laundry is contained inside the outer tank (1) in which the washing water is contained, to form a water flow on the inner bottom of the inner tank (2) The pulsator 3 is rotatably coupled.

그리고, 상기 외조(1)의 하측에는 모터와 클러치로 이루어진 구동부(4)가 배치되어 있고, 그 구동부(4)의 세탁축(5) 상단부가 상기 펄세이터(3)에 결합되어 펄세이터(3)를 정,역회전시킬 수 있도록 되어 있다.In addition, a driving unit 4 composed of a motor and a clutch is disposed below the outer tub 1, and an upper end of the washing shaft 5 of the driving unit 4 is coupled to the pulsator 3 so that the pulsator 3 is disposed. ) Can be rotated forward and reverse.

상기와 같이 구성되어 있는 종래 전자동 세탁기에서 내조(2)의 내부에 세탁물을 투입한 상태에서 세탁기의 동작버튼을 누르면 내조(2)의 내측으로 세탁수가 공급이 되고, 그와 같이 공급된 세탁수는 내조(2)와 외조(1)의 내측에 일정양 담긴다.In the conventional fully automatic washing machine configured as described above, pressing the operation button of the washing machine while the laundry is put in the inner tank 2, the washing water is supplied to the inner tank 2, and the washing water thus supplied is A certain amount is contained in the inner tank 2 and the outer tank 1.

그런후, 구동부(4)에서 세탁축(5)을 정,역회전시키면 그 세탁축(5)의 단부에 결합되어 있는 펄세이터(3)가 정,역회전되며 내부에 회전 수류와 하트 수류를 형성하며 세탁물의 세탁이 이루어지게 된다.Then, when the washing shaft 5 is rotated forward and reverse in the driving unit 4, the pulsator 3 coupled to the end of the washing shaft 5 is rotated forward and reverse, and the rotating water flow and the heart water flow therein. It is formed and the laundry is made.

또한, 상기와 같이 일정시간 세탁이 진행된 후에는 탈수가 이루어지는데, 탈수시에는 배수가 이루어짐과 동시에 세탁축(5)과 탈수축(미도시)이 동시에 회전이 되며 펄세이터(3)와 내조(2)가 동시에 회전이 되어 원심력에 의한 원심탈수가 이루어 진다.In addition, dehydration is performed after washing for a predetermined time as described above, during dehydration, the drainage is made and the washing shaft 5 and the dehydration shaft (not shown) are simultaneously rotated, and the pulsator 3 and the inner tank ( 2) is rotated at the same time and centrifugal dehydration is performed by centrifugal force.

그러나, 상기와 같은 종래의 전자동 세탁기의 세탁방식은 펄세이터(3)의 정,역회전으로 발생되는 회전 수류와 하트 수류의 유동에 의한 세탁이 이루어지게 되는데, 그와 같은 회전 수류와 하트 수류를 형성하기 위해서는 많은 세탁수를 필요로하여 비효율적인 세탁이 이루어지는 문제점이 있었고, 포의 엉킴이 많이 발생될뿐 아니라, 그와 같은 상태로 탈수가 이루어져서 진동 및 소음이 많이 발생되는 문제점이 있었다.However, in the conventional washing method of the automatic washing machine, washing is performed by the flow of the rotational water and the heart water generated by the forward and reverse rotation of the pulsator 3, and the rotational water and the heart water flow as such. In order to form, there was a problem that requires a lot of washing water inefficient washing, not only a lot of entangled fabric, but also made a lot of vibration and noise by dehydration in such a state.

상기와 같은 문제점을 감안하여 안출한 본 발명의 목적은 펄세이터에 의한 물리적인 세탁이 이루어지도록 하여 세탁수가 적게 들고 포의 엉킴 및 탈수시 진동 소음이 발생되는 것이 방지되도록 하는데 적합한 전자동 세탁기를 제공함에 있다.The object of the present invention devised in view of the above problems is to provide a fully automatic washing machine suitable for physical washing by the pulsator is made to be less wash water and to prevent the generation of vibration noise during tangling and dehydration of the fabric. have.

그리고, 상기 외조(101)의 하측에는 모터와 클러치로 이루어진 구동부(104)가 배치되어 있고, 그 구동부(104)의 세탁축(105) 상단부에 상기 펄세이터(103)가 헛돌도록 유니버셜 조인트(106)로 결합되어 있다.In addition, a driving unit 104 including a motor and a clutch is disposed below the outer tub 101, and the universal joint 106 is disposed so that the pulsator 103 floats on the upper end of the washing shaft 105 of the driving unit 104. ) Are combined.

그리고, 도 5에 도시된 바와 같이, 상기 펄세이터(103)의 하면에는 원형으로 4개의 펄세이터 가이드(107)들이 형성되어 있다.As illustrated in FIG. 5, four pulsator guides 107 are formed on a lower surface of the pulsator 103 in a circular shape.

또한, 상기 펄세이터(103)의 하측에는 세탁축(105)에 고정되도록 회전판(110)이 설치되어 있고, 그 회전판(110)의 상면에는 상기 펄세이터 가이드(107)에 접촉되며 펄세이터(103)를 상,하방향으로 동작시키기 위한 4개의 회전 가이드(111)가 도 3과 같이 원형으로 설치되어 있다.In addition, the lower side of the pulsator 103 is provided with a rotating plate 110 to be fixed to the washing shaft 105, the upper surface of the rotating plate 110 in contact with the pulsator guide 107 and the pulsator 103 ), Four rotation guides 111 for operating in the up and down directions are provided in a circular shape as shown in FIG. 3.

그리고, 상기 회전가이드(111)는 도 4에 도시된 바와 같이, 몸체부(111a)의 상단부 일측은 상기 펄세이터 가이드(107)의 하면에 접촉되며 회전될 수 있도록 라운드부(111b)가 형성되어 있고, 반대쪽은 역방향으로 회전시 펄세이터 가이드(107)에 걸리도록 수직걸림부(111c)가 형성되어 있다.And, as shown in Figure 4, the rotation guide 111, the upper end side of the body portion 111a is in contact with the lower surface of the pulsator guide 107 is formed round portion 111b so that it can be rotated On the other side, the vertical catching portion 111c is formed to be caught by the pulsator guide 107 when rotating in the reverse direction.

상기와 같이 구성되어 있는 본 발명 전자동 세탁기에서 세탁시에는 내조(102)의 내부에 세탁물을 투입한 상태에서 세탁기의 동작버튼을 누르면 내조(102)의 내측으로 세탁수가 공급이 되고, 그와 같이 공급된 세탁수는 내조(102)와 외조(101)의 내측에 일정양 담긴다.When washing in the present invention fully automatic washing machine configured as described above, pressing the operation button of the washing machine in the state in which the laundry is put into the inner tub 102, the washing water is supplied to the inner tub 102, and so supplied The washed water is contained in a predetermined amount inside the inner tank 102 and the outer tank 101.

그런후, 구동부(104)에서 세탁축(105)을 정회전시키면 그 세탁축(105)에 고정되어 있는 회전판(110)이 회전을 하고, 그 회전판(110)의 상면에 설치되어 있는 회전가이드(111)들이 회전을 하며 라운드부(111b)가 도 6에서와 같이 펄세이터 가이드(107)의 하면에 접촉하게 되는데, 그와 같이 회전가이드(111)에 접촉되는 펄세이터(103)는 상측으로 상승을 하고, 회전가이드(111)가 펄세이터 가이드(107)의 캠곡면부를 지나면 펄세이터(103)가 다시 하강을 하며 회전판(110)의 회전에 따라 그와 같은 승강동작을 반복하며 세탁물의 물리적인 세탁이 이루어지게 된다.Thereafter, when the washing shaft 105 is rotated forward by the driving unit 104, the rotating plate 110 fixed to the washing shaft 105 rotates, and the rotating guide installed on the upper surface of the rotating plate 110 ( 111 rotates and the round part 111b comes into contact with the lower surface of the pulsator guide 107 as shown in FIG. 6, and the pulsator 103 that contacts the rotation guide 111 ascends upward. When the rotation guide 111 passes through the cam curved portion of the pulsator guide 107, the pulsator 103 descends again and repeats the lifting operation according to the rotation of the rotating plate 110, thereby physically washing the laundry. Washing is done.

일정시간 세탁이 이루어진 후 탈수모드로 전환이 되어 탈수가 이루어질때는, 구동부(104)에서 세탁축(105)을 역회전시키게 되는데, 그에 따라 회전판(110)이 역회전이 되며, 도 7에서와 같이 회전판(110)의 상면에 설치된 회전가이드(111)의 수직경사부(111c)가 펄세이터 가이드(107)의 급경사면에 걸리게 되어 펄세이터(103)와 함께 고속으로 회전이 되어 원심 탈수가 이루어지게 된다.When the dehydration is performed after the washing is performed for a certain time, the dehydration is performed. The washing shaft 105 is reversely rotated by the driving unit 104. Accordingly, the rotating plate 110 is reversely rotated, as shown in FIG. The vertical inclined portion 111c of the rotation guide 111 installed on the upper surface of the rotating plate 110 is caught by the steep inclined surface of the pulsator guide 107 to be rotated at high speed together with the pulsator 103 so that centrifugal dehydration is performed. do.

이상에서 상세히 설명한 바와 같이, 본 발명의 전자동 세탁기는 펄세이터가 상,하방향으로 승강되며 세탁물의 물리적인 세탁이 이루어지도록 하여, 종래와 같이 수류에 의한 세탁이 이루어질때 보다 물의 사용량을 감소시키는데 따른 세탁효율의 증가효과가 있고, 포꼬임이 방지될뿐 아니라, 그에 따라 탈수시에 진동,소음이 발생되는 것을 방지되는 효과가 있다.As described above in detail, the fully automatic washing machine of the present invention allows the pulsator to be lifted up and down and physically wash the laundry, thereby reducing the amount of water used when washing by water flow as in the prior art. There is an effect of increasing the washing efficiency, foaming is not only prevented, accordingly there is an effect of preventing vibration, noise generated during dehydration.
