본 발명은 식기세척기의 보조아암구조에 관한 것으로서, 더욱 상세하게는 식기세척기의 상부스프레이아암과 연통되는 급수가이드에 회전가능하게 장착된 보조아암에 의해 세척수를 보다 넓은 영역에 골고루 분사시킬 수 있도록 한 것이다.The present invention relates to a secondary arm structure of a dishwasher, and more particularly, to allow the washing water to be evenly sprayed in a wider area by an auxiliary arm rotatably mounted to a water supply guide communicating with an upper spray arm of the dishwasher. will be.

종래의 식기세척기는 제1도 및 제2도에 나타낸 바와 같이, 터브(1)의 하부에 설치된 순환펌프(10)에 의해 터브(1)내의 상, 하부 스프레이아암(2)(11)으로 세척수가 공급되어 상, 하부 스프레이아암(2)(11)의 분사노즐(8)을 통해 분사되면 세척수의 분사압력에 의해 상, 하부랙(12)(13)에 얹혀진 식기(9)에 부착되어 있는 오물이 식기로부터 떨어지게 되고, 떨어진 오물은 상기 터브(1) 하단의 필터(14)에 의해 걸러지게 되며, 세척수는 순환펌프(10)에 의해 세척 및 헹굼과정을 반복한 후 배수된다. 이때, 상부스프레이아암(2)은 상, 하부에 각각 분사노즐(8)이 설치되어 있어서 하부랙(13)에 얹혀져 있는 식기(9)는 내, 외부 모두 깨끗하게 세척되고, 상부스프레이아암(2)과 연통되는 급수가이드(3)에는 보조 세척수단으로서 복수개의 유로가이드(5a)가 있는 보조아암(4a)이 회전가능하게 장착되어 상기 상부스프레이아암(2)상의 분사노즐(8)에서 분사되는 세척수를 타격하여 넓은 영역으로 뿌려주게 된다. 그러나, 이와같은 종래 식기세척기의 보조아암(4a)은 하부둘레면에 나선형으로된 복수개의 유로가이드(5a)가 동일한 높이로 형성되어 있기 때문에 세척수의 분사영역이 한정을 받게 되고 따라서 세척수의 분사영역이 넓은 경우에는 보조아암(4a)의 반경이 커져야 하므로 식기(9)에 보조아암(4a)이 닿게되는 등의 문제점이 있다.Conventional dishwashers are washing water to the upper and lower spray arms (2) (11) in the tub (1) by the circulation pump 10 installed in the lower part of the tub (1) as shown in FIG. Is supplied and sprayed through the spray nozzles 8 of the upper and lower spray arms 2 and 11, and are attached to the dishes 9 mounted on the upper and lower racks 12 and 13 by the spray pressure of the washing water. The dirt is dropped from the dishes, the dirt is filtered by the filter 14 at the bottom of the tub 1, the washing water is drained after repeating the washing and rinsing process by the circulation pump (10). At this time, the upper spray arm (2) has a spray nozzle (8) is installed on the upper and lower, respectively, the tableware (9) mounted on the lower rack 13 is cleaned both inside and outside, the upper spray arm (2) The water supply guide (3) communicating with the water is rotatably mounted to the auxiliary arm (4a) having a plurality of flow path guides (5a) as an auxiliary washing means to be sprayed from the injection nozzle (8) on the upper spray arm (2) Scatter to spread a large area. However, since the auxiliary arm 4a of the conventional dishwasher has a plurality of helical flow channel guides 5a formed on the lower circumferential surface at the same height, the spraying area of the washing water is limited and thus the spraying area of the washing water. In this wide case, since the radius of the auxiliary arm 4a must be large, there is a problem such that the auxiliary arm 4a comes into contact with the tableware 9.

본 발명은 상기한 제반문제점을 해결하기 위한 것으로서, 본 발명은 식기세척기의 상부스프레이아암과 연통되는 급수가이드에 회전가능하게 장착된 보조아암으로 보다 넓은 영역으로 골고루 세척수를 분사시킬 수 있도록 하여 식기의 세척효율을 향상시킬 수 있는 식기세척기의 보조아암구조를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention is a secondary arm rotatably mounted to the water supply guide communicating with the upper spray arm of the dishwasher to distribute the washing water evenly to a wider area of the tableware. An object of the present invention is to provide a secondary arm structure of a dishwasher which can improve washing efficiency.

상기한 목적을 달성하기 위한 본 발명의 실시예에 따라 터브에 설치된 상부스프레이아암과 연통되는 급수가이드에 회전가능하게 장착된 보조아암에 유로가이드의 높이가 분사되는 세척수를 넓은 영역으로 뿌려주도록 유도하기 위해 중앙부에서 외주방향으로 갈수록 낮아지게 형성된 식기세척기의 보조아암이 제공된다.According to an embodiment of the present invention for achieving the above object to induce to spray a large area of the spray water is sprayed in the height of the flow guide to the auxiliary arm rotatably mounted to the water supply guide in communication with the upper spray arm installed in the tub The auxiliary arm of the dishwasher is lowered toward the outer circumferential direction from the center.

이하, 본 발명의 일실시예를 첨부도면 제3도 내지 제5도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 5.

제3도는 본 발명에 따른 식기세척기를 나타낸 종단면도이고, 제4도는 본 발명을 나타낸 사시도이며, 제5도는 제3도의 A부분 확대도로서, 식기세척기의 터브(1)내에 설치된 상부스프레이아암(2)과 연통되는 급수가이드(3)에 회전가능하게 장착되는 보조아암(4)의 하부둘레면에 복수개의 나선형으로 형성된 유로가이드(5)의 높이가 분사되는 세척수를 넓은 영역으로 뿌려주도록 유도하기 위해 유로가이드(5)의 중앙부에서 외주방향으로 갈수록 낮아지게 형성되고, 유로가이드(5)의 경사각도(α)가 90°보다 크게 형성된다.FIG. 3 is a longitudinal sectional view showing the dishwasher according to the present invention, FIG. 4 is a perspective view showing the present invention, and FIG. 5 is an enlarged view of a portion A of FIG. 3, and an upper spray arm installed in the tub 1 of the dishwasher. 2) to induce the spray water to be sprayed to a wide area the height of the plurality of spirally formed flow path guide 5 to the lower peripheral surface of the auxiliary arm (4) rotatably mounted to the water supply guide (3) in communication with In order to decrease from the central portion of the flow path guide 5 toward the outer circumferential direction, the inclination angle α of the flow path guide 5 is greater than 90 °.

또한, 보조아암(4) 하단의 급수가이드(3)에는 세척수가 나갈 수 있도록 중공으로 형성되고 보조아암(4)의 유로가이드(5)를 타격하여 회전시키는 복수개의 안내핀(6)이 상기 보조아암(4)과의 접촉면적을 최소화할 수 있도록 일정각도 경사지게 설치되어 구성된다.In addition, the water supply guide (3) at the bottom of the auxiliary arm (4) has a plurality of guide pins (6) which are formed in a hollow so that the washing water can go out, and hit by rotating the flow guide (5) of the auxiliary arm (4) It is configured to be inclined at an angle so as to minimize the contact area with the arm (4).

이와같이 구성된 본 발명은 제3도 내지 제5도에 나타낸 바와 같이, 식기세척기의 세척펌프에 의해 가압된 세척수가 터브(1) 내의 급수관(7)을 통해 유입되면, 급수관(7)과 연통되는 급수가이드(3)에 세척수가 유입됨과 동시에, 급수가이드(3)에 연통된 상부스프레이아암(2)으로 세척수가 공급되어 상부스프레이아암(2)의 상, 하부에 설치된 분사노즐(8)로 세척수가 분사된다.According to the present invention configured as described above with reference to FIGS. 3 to 5, when the washing water pressurized by the washing pump of the dishwasher flows in through the water supply pipe 7 in the tub 1, the water supply communicated with the water supply pipe 7. At the same time as the washing water flows into the guide 3, the washing water is supplied to the upper spray arm 2 communicated with the water supply guide 3, and the washing water is supplied to the spray nozzles 8 installed at the upper and lower portions of the upper spray arm 2. Sprayed.

이와 동시에, 급수가이드(3)에 회전가능하게 장착된 보조세척수단인 보조아암(4) 하단의 급수가이드(3)에 상기 보조아암(4)의 회전시 접촉면적을 줄여서 지지하도록 일정각도 경사지게 형성되어 세척수가 나갈 수 있도록 중공으로 형성된 복수개의 안내핀(6)으로도 세척수가 공급됨과 동시에, 상기 공급되는 세척수가 보조아암(4) 하부 둘레면에 나선형으로 된 복수개의 유로가이드(5)를 타격하여 보조아암(4)이 회전하게 되므로 세척수는 보조아암의 회전방향을 따라 원주방향으로 비산하면서 식기(9)에 분사된다.At the same time, the water supply guide 3 of the lower side of the auxiliary arm 4, which is rotatably mounted to the water supply guide 3, is formed to be inclined at a predetermined angle so as to reduce and support the contact area when the auxiliary arm 4 rotates. The washing water is also supplied to the plurality of guide pins 6 formed in a hollow so that the washing water can be discharged, and at the same time, the supplied washing water strikes the plurality of spirally guided flow path guides 5 on the lower circumferential surface of the auxiliary arm 4. As the auxiliary arm 4 rotates, the washing water is sprayed onto the dish 9 while flying in the circumferential direction along the rotational direction of the auxiliary arm.

이때, 보조아암(4) 하부 둘레면의 나선형으로 된 복수개의 유로가이드(5)의 높이가 유로가이드(5)의 중앙부에서 외주방향으로 갈수록 낮아지고 또한 유로가이드(5)의 경사각도(α)가 90°보다 크게 형성되어 있기 때문에 상기 보조아암(4)이 회전할 때 유로가이드(5)는 세척수가 골고루 넓은 범위에 뿌려지도록 유도하여 식기(9)의 세척효율을 크게 향상시킬 수 있게 된다.At this time, the height of the helical flow path guides 5 in the circumferential surface of the lower side of the auxiliary arm 4 is lowered toward the outer circumferential direction from the center portion of the flow path guide 5, and the inclination angle α of the flow path guide 5 is reduced. Is formed larger than 90 °, when the auxiliary arm 4 is rotated, the flow guide 5 can guide the washing water to be evenly spread over a wide range to greatly improve the washing efficiency of the dish (9).

이상에서와 같이, 본 발명은 급수가이드(3)에 회전가능하게 장착된 보조아암(4)의 하부 둘레면에 중앙부에서 외주방향으로 갈수록 점차 높이가 낮아지는 형상의 유로가이드(5)를 형성하여 세척수를 골고루 넓은 범위에 뿌려줄 수 있으므로 세척효율의 향상을 가져오게 된다.As described above, the present invention forms a flow path guide 5 of a shape that gradually decreases in height from the center to the outer circumferential direction on the lower circumferential surface of the auxiliary arm 4 rotatably mounted to the water supply guide 3 Since the washing water can be sprayed evenly over a wide range, the washing efficiency is improved.
