Description

세탁기의 교반장치Agitator of washing machine

본 발명은 회전수류를 일으켜 빨래감이 비벼지며 세탁 되도록한 세탁기의 교반장치에 관한 것이다. 일반적으로 세탁기는 도 1에 도시된 바와 같이 본체(1) 내부에 수조(2)가 매달려 설치되고 수조(2) 내부에 세탁조(3)가 구비된다. 또한 세탁조(3) 내부에 수류를 일으키는 펄세이터(4)가 설치되고 수조(2) 저면에 세탁조(3)와 펄세이터(4)를 선택적으로 구동시키는 동력절환부재(6)가 설치된다. 동력절환부재(6)는 모터(5)로 구동되고 동력절환부재(6)의 세탁축(6a)이 펄세이터(4)와 연결되고 탈수축(6b)이 세탁조(3)와 연결된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agitating device for a washing machine, which causes washing water to be washed by rotating water flow. Generally, as shown in FIG. 1, a washing machine is provided with a water tub 2 suspended inside a main body 1 and a washing tub 3 inside a water tub 2. A pulsator 4 for generating a water current is provided in the washing tub 3 and a power switching member 6 for selectively driving the washing tub 3 and the pulsator 4 is provided on the bottom surface of the tub 2. [ The power switching member 6 is driven by the motor 5 and the washing shaft 6a of the power switching member 6 is connected to the pulsator 4 and the dewaxing shaft 6b is connected to the washing tub 3.

이처럼 구성된 세탁기는 세탁시 세탁조(3) 내부에 빨래감과 세탁수가 공급되고 모터(5)의 구동으로 동력절환부재(6)의 세탁축(6a)이 정역회전 되면 펄세이터(4)에 의해 수류가 일어나면서 빨래감이 비벼지며 세탁이 진행된다. 또한 세탁 완료후 세탁수가 배수되고 동력절환부재(6)의 탈수축(6b)에 의해 세탁조(3)가 고속으로 회전되면 원심력에 의해 빨래감이 탈수된다.In the washing machine constructed as described above, when laundry and washing water are supplied into the washing tub 3 during washing and the washing shaft 6a of the power switching member 6 is rotated normally and reversely by the driving of the motor 5, The laundry is rubbed while washing, and washing is carried out. When the washing water is drained after the completion of washing and the washing tub 3 is rotated at high speed by the dehydrating shrinkage 6b of the power switching member 6, the laundry feeling is dewatered by the centrifugal force.

종래의 펄세이터(4)는 상부에 형성된 날개가 회전되면서 단순한 회전수류를 일으키기 때문에 빨래감이 꼬일 우려가 있고 또한 펄세이터(4)를 여러번 정역회전 시켜 빨래감을 비벼야 됨으로 세탁시간이 오래 걸리는 등의 문제점이 있다.Since the conventional pulsator 4 rotates the wings formed on the upper part to generate a simple rotating water flow, the laundry may be twisted and the pulsator 4 may be rotated several times to rotate the laundry several times, There is a problem.

본 발명은 이러한 문제점을 감안하여 개발된 것으로서, 그 목적은 펄세이터의 상부에 방사상으로 설치된 각 날개가 펄세이터의 정역회전시 원심력에 의해 벌어지면서 상승되도록 함으로서, 수류가 복합적으로 일어나도록한 세탁기의 교반장치를 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a washing machine in which a plurality of wings radially installed on a pulsator are lifted up by centrifugal force when rotating the pulsator in normal and reverse directions, And a stirring device.

이하 본 발명의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명 교반장치의 분리 사시도 로서, 도 1과 동일 구성요소는 동일 부호를 사용하여 본 발명을 설명한다. 수조(2) 내부에 동력절환부재(6)의 탈수축(6b)과 결합되어 고속 회전되는 세탁조(3)가 설치되고 세탁조(3) 내부에 펄세이터(10)가 설치된다. 펄세이터(10)는 동력절환부재(6)의 세탁축(6a)과 결합되어 정역회전 되면서 회전수류를 일으킨다. 이러한 펄세이터(10)는 회전통(20)이 구비되고 회전통(20) 내부에 방사상으로 다수개의 이동체(30)가 설치된다.Fig. 2 is an exploded perspective view of the stirring device of the present invention. The same components as those in Fig. 1 are denoted by the same reference numerals, and the present invention will be described. A washing tub 3 which is coupled with the dew condensation shaft 6b of the power switching member 6 and rotated at a high speed is provided in the water tub 2 and a pulsator 10 is installed inside the washing tub 3. The pulsator 10 is engaged with the washing shaft 6a of the power switching member 6 and rotated in the forward and reverse directions to generate a rotating water flow. The pulsator 10 is provided with a rotating body 20 and a plurality of moving bodies 30 are installed radially inside the rotating body 20.

또한 회전통(20)의 개방된 상부를 덮는 커버(40)가 구비되고 커버(40)에는 각 이동체(30)와 대응토록 통로(41)가 방사상으로 다수개 형성된다. 또한 각 이동체(30)의 상부에 해당 통로(41)를 따라 커버(40) 상부로 돌출되는 날개(31)가 형성되고 커버(40)의 저면 중앙에 고정봉(42)이 형성된다. 또한 각 이동체(30)의 후방과 고정봉(42) 사이에 스프링(50)이 설치되어 각 이동체(30)를 회전통(20)의 중심 쪽으로 이동시킨다.A cover 40 is provided to cover the opened upper portion of the rotator 20 and a plurality of passages 41 are formed radially in correspondence with the moving bodies 30 in the cover 40. A wing 31 protruding above the cover 40 is formed on the upper portion of each movable body 30 along the passage 41 and a fixing rod 42 is formed at the center of the bottom of the cover 40. A spring 50 is provided between the rear of each movable body 30 and the fixed rod 42 to move each movable body 30 toward the center of the rotary body 20.

또한 회전통(20)의 바닥이 상부로 확대 경사진 경사면(21)이 형성되고 각 이동체(30)의 저면에 경사면(33)과 대응되는 경사면이 형성된다. 또한 각 이동체(30)의 전방에 무게추(32)가 형성되어 회전통(20)의 회전시 원심력이 작용되어 이동체(30)를 회전통(20)의 외주연 쪽으로 강제 이동시킨다. 미설명부호 22는 동력절환부재(6)의 세탁축(6a)과 결합되도록 회전통(20)의 저면에 형성된 축받이를 나타낸다.In addition, a slope 21 is formed at the bottom of the rotor 20 so as to be inclined upward and an inclined surface corresponding to the slope 33 is formed on the bottom surface of each moving body 30. A weight 32 is formed in front of each moving body 30 so that centrifugal force acts upon the rotating body 20 to move the moving body 30 toward the outer circumferential side of the rotating body 20. Reference numeral 22 denotes a bearing formed on the bottom surface of the rotor 20 so as to engage with the washing shaft 6a of the power switching member 6. [

이처럼 구성된 본 발명은 회전통(20) 내부의 공간부에 방사상으로 다수개의 이동체(30)가 놓이고 각 이동체(30)의 후방과 고정봉(42) 사이에 스프링(50)이 설치된다. 또한 회전통(20)의 상부에 커버(40)가 덮혀 고정되고 커버(40)에 형성된 다수개의 통로(41)에 해당 이동체(30)의 날개(31)가 끼워져외부로 돌출된다.In the present invention constructed as described above, a plurality of moving bodies 30 are radially disposed in a space portion inside the rotary tub 20, and a spring 50 is installed between the rear of each moving body 30 and the fixed rods 42. The cover 40 is covered and fixed to the upper portion of the rotator 20 and the wings 31 of the moving body 30 are inserted into the plurality of passages 41 formed in the cover 40 and protruded to the outside.

이 같이 조립된 본 발명은 동력절환부재(6)의 세탁축(6a)이 정역 회전될 때 펄세이터(10)를 구성하는 회전통(20)과 커버(40)가 정역회전 된다. 즉 세탁축(6a)이 정역회전 되면 각 이동체(30)가 원심력에 의해 외측으로 벌어진다. 이때 스프링(50)은 인장된 상태가 되고 이동체(30)가 벌어질 때 무게추(32)에 의해 원심력이 작용되어 이동체(30)의 벌어지는 힘이 증가된다.In the present invention assembled like this, the rotator 20 constituting the pulsator 10 and the cover 40 are rotated in the forward and reverse directions when the washing shaft 6a of the power switching member 6 rotates normally. That is, when the washing shaft 6a rotates in the forward and reverse directions, each moving body 30 is opened to the outside by the centrifugal force. At this time, the spring 50 is in a tensioned state and a centrifugal force is applied by the weight 32 when the moving body 30 is opened, so that the moving force of the moving body 30 is increased.

또한 이동체(30)가 벌어질 때 각 경사면(21)(33)에 의해 이동체(30)가 상승되면서 벌어짐으로 수류가 복합적으로 일어나고 또한 이동체(30)가 상승될 때 날개(31)가 빨래감에 충돌되어 빨래감이 두둘겨지는 효과가 있다. 또한 세탁축(6a)이 역회전을 위해 순간적으로 정지되면 인장된 스프링(50)이 복원되면서 그 복원력에 의해 각 이동체(30)가 회전통(20)의 중심 쪽으로 이동되어 원위치 된다. 이후 세탁축(6a)이 역회전 되면 정회전될 때 와 동일하게 이동체(30)가 이동되면서 세탁이 진행된다.When the moving body 30 is lifted, the moving body 30 is lifted by the inclined faces 21 and 33 so that the water flow is generated due to the widening and the wing 31 collides with the laundry when the moving body 30 is lifted There is an effect that the laundry feeling is put in two. When the washing shaft 6a is instantaneously stopped for the reverse rotation, the tensioned spring 50 is restored, and each moving body 30 is moved toward the center of the rotating body 20 by the restoring force and restored. Thereafter, when the washing shaft 6a is reversely rotated, the moving body 30 is moved in the same manner as in the case of forward rotation, and the washing is progressed.

본 발명에 따르면 펄세이터를 구성하는 회전통 내부에 방사상으로 다수개의 이동체가 설치되고 각 이동체 상부에 날개가 형성된다. 이 같은 상태에서 회전통이 정역회전 되면 각 이동체가 외측으로 벌어지면서 회전되고 회전수류가 발생된다. 또한 각 이동체와 회전통 바닥에 경사면이 형성되어 이동체가 벌어질 때 각 날개가 상승되고 이때 빨래감이 두둘겨 지는 등의 효과가 있다.According to the present invention, a plurality of moving bodies are installed in a radial direction inside the rotating body constituting the pulsator, and wings are formed on the moving bodies. In this state, when the rotator is rotated in the forward and reverse directions, each moving body is rotated while being opened to the outside, and a rotating water flow is generated. In addition, each of the moving body and the bottom of the tread is formed with an inclined surface, so that when the moving body is opened, each wing is raised and the washing feeling is doubled at this time.
