Description

세탁기의 교반장치Agitator of washing machine

본 발명은 회전수류를 일으켜 빨래감이 비벼지며 세탁되도록한 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 외주연에 다수개의 회전부재를 설치하여 펄세이터의 회전에 따른 회전수류와 회전부재의 회전에 따른 회전수류가 복합적으로 일어나 세탁성이 향상되도록한 세탁기의 교반장치를 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been developed in view of such problems, and its object is to provide a washing machine having a plurality of rotating members installed on the outer periphery of a pulsator, and a rotating water flow accompanying rotation of the pulsator and a rotating water flow accompanying rotation of the rotating member, Thereby improving the performance of the washing machine.

본 발명은 상기 목적을 달성하기 위하여 수조 내부에 세탁조와 펄세이터가 설치되어 동력절환부재의 작동에 따라 선택적으로 회전됨에 있어서, 상기 펄세이터의 외주면에 구동기어가 형성되고 상기 세탁조의 내주연에 방사상으로 다수개의 회전부재가 설치되어 상기 구동기어와 치합되어 회전되는 특징이 있다.In order to achieve the above object, a washing tub and a pulsator are installed in a water tank and selectively rotated according to the operation of the power switching member. In this case, a driving gear is formed on the outer circumferential surface of the pulsator, A plurality of rotation members are provided and rotated by engaging with the driving gear.

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 세탁조(3)가 설치되어 탈수시 동력절환부재(6)의 탈수축(6b) 회전에 따라 고속회전 된다. 또한 세탁조(3) 내부에 펄세이터(10)가 설치되어 동력절환부재(6)의 세탁축(6a)이 정역회전 될 때 정역회전 되어 회전수류가 발생된다. 또한 펄세이터(10)의 외주면에 구동기어(11)가 형성되어 펄세이터(10)의 정역회전시 함께 정역회전 된다. 또한 세탁조(3)의 내주연에 방사상으로 다수개의 회전부재(20)가 설치되어 구동기어(11)의 정역회전에 따라 함께 정역회전 되면서 회전수류를 일으킨다.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 is provided inside the water tub 2 and is rotated at a high speed in accordance with the rotation of the damping shafts 6b of the power switching member 6 during dewatering. The pulsator 10 is installed in the washing tub 3 to rotate the washing shaft 6a of the power switching member 6 in the forward and reverse directions. In addition, a drive gear 11 is formed on the outer circumferential surface of the pulsator 10 to rotate forward and backward together with the pulsator 10 in normal and reverse rotation. A plurality of rotary members 20 are provided radially around the inner periphery of the washing tub 3 and are rotated together with the driving gear 11 in the normal and reverse directions to generate rotating water flow.

각 회전부재(20)는 구동기어(11)와 치합되는 종동기어(23)가 하단에 형성된 회전축(21)이 구비되고 각 회전축(21)에 방사상으로 다수개의 날개(22)가 형성된다. 또한 세탁조(3)의 내주면 상,하측에 각 회전축(21)의 상,하단을 회전지지하는 상,하측받이부(24)(25)가 형성되어 날개(22)가 회전 지지 된다. 또한 각 날개(22)에 다단으로 구멍(26)이 형성되어 날개(22)의 회전시 세탁물과의 마찰력이 감소된다.Each rotary member 20 is provided with a rotary shaft 21 having a driven gear 23 at its lower end engaged with the driving gear 11 and a plurality of blades 22 radially formed on each rotary shaft 21. Upper and lower receiving portions 24 and 25 for rotatably supporting the upper and lower ends of the rotary shafts 21 are formed on the inner circumferential surface and the lower surface of the washing tub 3 so that the blades 22 are rotatably supported. In addition, a plurality of holes 26 are formed in each of the blades 22, so that the frictional force with the laundry when the blades 22 are rotated is reduced.

이처럼 구성된 본 발명은 펄세이터(10)의 외주면에 구동기어(11)가 형성되고 세탁조(3)의 내주연에 방사상으로 다수개의 날개(22)가 설치되어 펄세이터(10)의 정역회전시 함께 정역회전 되면서 회전수류를 발생시킨다. 즉 날개(22)의 상,하측으로 돌출된 회전축(21)을 세탁조(3)의 내주면 상,하측에 형성된 상,하측받이부(24)(25)에 회전 가능토록 끼운다. 그리고 회전축(21)의 하단에 형성된 종동기어(23)를 펄세이터(10)의 외주연에 형성된 구동기어(11)에 치합시키면 본 발명이 조립된다.The present invention configured as described above is characterized in that the driving gear 11 is formed on the outer circumferential surface of the pulsator 10 and a plurality of vanes 22 are installed radially on the inner circumference of the washing tub 3 to rotate the pulsator 10 Rotating water flow is generated while rotating in the normal direction. The rotary shaft 21 protruding upward and downward from the blade 22 is rotatably fitted on the upper and lower receiving portions 24 and 25 formed on the inner circumferential surface of the washing tub 3 at the lower side. And the driven gear 23 formed at the lower end of the rotary shaft 21 is engaged with the drive gear 11 formed on the outer periphery of the pulsator 10 to assemble the present invention.

이 같은 상태에서 동력절환부재(6)의 세탁축(6a)이 정역회전되면 펄세이터(10)가 함께 정역회전 된다. 이때 구동기어(11)가 함께 정역회전 되고 이 과정에서 회전축(21)의 종동기어(23)가 함께 정역회전 된다. 또한 종동기어(23)가 정역회전 되면 회전축(21)과 날개(22)가 함께 정역회전 되고 날개(22)의 회전으로 세탁조(3) 내주연 측에 회전수류가 발생된다.In this state, when the washing shaft 6a of the power switching member 6 is rotated normally or reversely, the pulsator 10 rotates together with the pulsator. At this time, the driving gear 11 is rotated together with the driven gear 11, and the driven gear 23 of the rotating shaft 21 rotates together with the driven gear 11. When the driven gear 23 rotates in the forward and reverse directions, the rotary shaft 21 and the blades 22 rotate together in the forward and reverse directions, and the rotation of the blades 22 generates a rotating water flow on the peripheral side in the washing tub 3.

펄세이터(10)가 회전될 때 발생되는 회전수류와는 별도로 세탁조(3) 내주연에 방사상으로 다수개 설치된 각 날개(22)에서 회전수류가 발생됨으로 수류가 복합적으로 일어난다. 또한 각 날개(22)가 회전되는 과정에서 빨래감이 충돌되어 비벼짐으로 세탁성이 향상된다.A rotating water flow is generated in each of the vanes 22 radially arranged at the periphery of the washing tub 3 separately from the rotating water flow generated when the pulsator 10 rotates, so that water streams are generated in a complex manner. In addition, the washing feeling is increased by colliding with the laundry feeling in the process of rotating each blade (22).

본 발명에 따르면 펄세이터 외주면에 구동기어가 형성되고 세탁조의 내주연에 구동기어와 치합되어 정역회전 되는 날개가 형성된다. 따라서 펄세이터의 회전으로 회전수류가 발생되고 각 날개가 세탁조의 내주연에서 회전수류를 발생시킴으로 수류가 복합적으로 일어난다. 또한 각 날개가 회전될 때 빨래감이 날개와 충돌되어 비벼짐으로 세탁성이 향상되는 등의 효과가 있다.According to the present invention, a driving gear is formed on the outer circumferential surface of the pulsator, and a blade is formed on the inner circumference of the washing tub to engage with the driving gear to rotate in the forward and reverse directions. Therefore, rotating water is generated by the rotation of the pulsator, and each wing generates rotating water flow at the inner periphery of the washing tub, resulting in a mixed water flow. Further, when each wing is rotated, the washing feeling is increased by colliding with the wing to improve the washing property.
