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 cause a simple rotating water flow, there is a possibility that the laundry feeling may be twisted and that the washing machine must rub the pulsator 4 by rotating the pulsator 4 several times, There is a problem.

본 발명은 이러한 문제점을 감안하여 개발된 것으로서, 그 목적은 세탁조의 내주면에 방사상으로 다수개의 타격부재를 설치하여 펄세이터가 정역회전될 때 각운동되면서 빨래감을 두둘기도록 함으로서, 세탁성이 향상되도록한 세탁기의 교반장치를 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been developed in view of such problems, and an object of the present invention is to provide a washing machine, in which a plurality of striking members are radially provided on the inner circumferential surface of a washing tub, To provide a stirring device for a washing machine.

A plurality of striking members 20 are installed radially below the inner circumferential surface of the washing tub 3, with rails 11 formed on the outer circumferential surface of the pulsator 10. The striking member 20 is angularly engaged with the rail 11 when the pulsator 10 is rotated in the forward and reverse directions.

이러한 타격부재(20)는 세탁조(3)의 내주면에 핀구멍(24a)을 갖는 한쌍의 힌지부(21)가 돌출 형성되고 핀구멍(24a)과 대응되는 핀구멍(24b)을 갖는 사다리꼴 형상의 타격봉(22)이 구비된다. 이때 각 핀구멍(24a)(24b)에 핀(24)이 끼워지면 타격봉(22)이 힌지부(21)에 회동 가능하게 설치되고 힌지부(21)와 타격봉(22) 사이에 스프링(25)이 설치되어 타격봉(22)을 세탁조(3)의 내주면 쪽으로 강제 이동 시킨다. 또한 타격봉(22)의 하부에 레일(11)과 구름접촉되는 바퀴(23)가 설치되고 레일(11)이 회전될 때 바퀴(23)가 승강된다.The striking member 20 is provided with a trapezoidal shape having a pair of hinge portions 21 protruding from the inner peripheral surface of the washing tub 3 and having a pin hole 24a and having a pin hole 24b corresponding to the pin hole 24a A striking rod 22 is provided. When the pin 24 is inserted into each of the pin holes 24a and 24b at this time, the striking rod 22 is rotatably installed on the hinge portion 21 and a spring (not shown) is provided between the hinge portion 21 and the striking rod 22. [ 25 are provided to force the impact rod 22 toward the inner peripheral surface of the washing tub 3. A wheel 23 is provided at a lower portion of the striking rod 22 so as to be in rolling contact with the rail 11. The wheel 23 is moved up and down when the rail 11 is rotated.

이처럼 구성된 본 발명은 세탁조(3)의 내주면에 한쌍의 힌지부(21)가 방사상으로 다수개 형성되고 이들 각 힌지부(21)에 타격봉(22)이 핀(24)을 중심으로 회동 가능하게 설치된다. 또한 각 타격봉(22)과 힌지부(21)사이에 스프링(25)이 설치되어 타격봉(22)을 세탁조(3)의 내주면 쪽으로 강제 이동시키고 타격봉(22) 저면에 바퀴(23)가 설치되어 레일(11)과 구름접촉 된다.A plurality of hinge portions 21 are radially formed on the inner circumferential surface of the washing tub 3 and the hitting rods 22 are rotatably mounted on the hinge portions 21 about the pins 24 Respectively. A spring 25 is provided between each of the striking rods 22 and the hinge portion 21 to force the striking rods 22 toward the inner circumferential surface of the washing tub 3 so that the wheels 23 And is brought into rolling contact with the rail 11.

이 같이 조립된 상태에서 동력절환부재(6)의 세탁축(6a)이 정역회전 되면 펄세이터(10)가 정역회전 되면서 회전수류가 발생된다. 이때 발생되는 회전수류에 의해 빨래감이 세탁물쌀에 의해 비벼지면서 세탁이 진행된다. 또한 펄세이터(10)가 정역회전 되는 동안 레일(11)이 함께 정역회전 되고 이 과정에서 바퀴(23)가 레일(11)을 따라 구름접촉 된다.When the washing shaft 6a of the power switching member 6 rotates in the forward and reverse directions in the assembled state, the pulsator 10 rotates in the forward and reverse directions to generate rotating water flow. At this time, the laundry is rubbed by the laundry rice due to the rotating water flow generated at this time, and the washing is progressed. In addition, the rail 11 is rotated together with the pulley 10 while the pulsator 10 is rotated in the forward and reverse directions, and in this process, the wheels 23 come into rolling contact along the rails 11.

바퀴(23)가 레일(11)과 구름접촉 되면 레일(11)의 요철을 따라 승강되고 바퀴(23)와 결합된 타격봉(22)이 핀(24)을 중심으로 각운동 된다. 타격봉(22)이 각운동 되면 세탁조(3)의 중심 쪽으로 이동됨으로 빨래감이 두둘겨 진다. 또한 세탁수가 타격봉(22)의 이동에 따라 방사상으로 힘을 받아 충렁거림으로 수류가 복합적으로 발생된다.When the wheels 23 come into rolling contact with the rails 11, the striking rods 22 lifted along the irregularities of the rails 11 and engaged with the wheels 23 are angularly moved around the fins 24. When the striking bar 22 is angularly moved, the laundry is moved to the center of the washing tub 3, so that the laundry feeling is doubled. In addition, the washing water receives radial force in accordance with the movement of the striking rod 22, and a water stream is generated in a complex manner due to the chattering.

또한 타격봉(22)이 각운동되는 동안 스프링(25)이 타격봉(22)을 하부 쪽으로 이동시켜 바퀴(23)가 레일(11)과 강제 접하도록 한다. 따라서 펄세이터(10)가 회전되는 동안 바퀴(23)는 레일(11)과 긴밀하게 접하면서 승강된다.And the spring 25 moves the striking bar 22 downward while the striking bar 22 is angularly moved so that the wheel 23 is forcibly brought into contact with the rail 11. [ Therefore, while the pulsator 10 is rotating, the wheels 23 are lifted and brought into close contact with the rails 11.

본 발명에 따르면 세탁조의 내주면에 방사상으로 다수개의 타격봉이 설치되고 펄세이터의 외주면에 요철형의 레일이 형성되어 각 타격봉이 바퀴를 통하여 레일과 접촉된다. 이 같은 상태에서 펄세이터가 정역회전 되면 각 타격봉이 힌지부의 핀을 중심으로 각운동 되고 각운동될 때 빨래감이 두둘겨 지면서 세탁된다. 또한 각 타격봉이 각운동 되는 과정에서 세탁수가 세탁조의 중심 방향으로 힘을 받아 충렁거림에 따라 회전수류와는 별도의 충렁거림으로 인하여 복합적인 수류가 발생되고 세탁성이 향상된다.According to the present invention, a plurality of striking rods are provided radially on the inner circumferential surface of the washing tub, and a rake-shaped rail is formed on the outer circumferential surface of the pulsator, so that the striking rods contact the rails through the wheels. In this state, when the pulsator is rotated in the forward and reverse directions, each striking rod is angularly moved around the pin of the hinge portion, and when the striking motion is performed, the striking clothes are doubled and washed. In addition, in the course of each movement of the striking rods, the washing water receives a force in the direction of the center of the washing tub, and a mixed water flow is generated due to churning separate from the rotating water flow according to the chattering.
