식기세척기의 분사아암 회전지지구조 { an spray arm support structure for a dish cleaner }{An spray arm support structure for a dish cleaner}

본 고안은 식기세척기의 세척수 분사아암의 회전결합부 상단 및 헹굼수 분사아암의 회전결합부 하단이 마모, 손상되는 것을 방지하면서 원활한 회전이 이루어지도록 하는 식기세척기의 분사아암 회전지지구조에 관한 것으로, 더 자세하게는회전중심축의 세척수 분사아암 회전결합부와 헹굼수 분사아암 회전결합부 사이에 내마모성이 뛰어난 세라믹링을 설치한 것에 관한 것이다.The present invention relates to a spray arm rotating support structure of the dishwasher for smooth rotation while preventing the wear and damage of the upper portion of the rotary coupling portion of the washing water jet arm of the dishwasher and the rinsing water injection arm, More particularly, the present invention relates to a ceramic ring having excellent wear resistance between the washing water injection arm rotary coupling portion and the rinsing water injection arm rotary coupling portion of the rotating shaft.

일반적으로 식기를 간편하게 세척할 수 있도록 하는 식기세척기는 전면에 개폐도아가 마련되는 본체의 내부 중앙부에 식기를 투입 설치할 수 있도록 하는 수납바구니가 설치되고, 본체의 내부 상부 및 내부 하부에 설치되는 회전중심축에 고압의 세척수를 분사할 수 있도록 하는 세척수 분사아암과 헹굼수를 분사할 수 있는 헹굼수 분사아암이 각각 설치되는 형태를 갖는 것이 보통이다.In general, a dishwasher for easily washing dishes is provided with a storage basket for inserting and installing dishes in the inner central part of the main body where opening and closing doors are provided at the front, and a rotation center installed at the upper and lower parts of the main body. It is common to have a form in which a washing water spray arm for spraying high pressure washing water and a rinsing water spray arm for spraying rinsing water are respectively installed on the shaft.

상기 식기세척기에 있어서 중공상의 회전중심축에 회전지지되는 세척수 분사아암은 그 상단면 또는 하단면에 다수의 분사구멍이 형성되어 세제가 포함된 세척수가 공급되면 각 분사구멍으로 토출되는 세척수의 분사압력을 통해 일방향으로 회전하면서 본체 내부 중앙에 설치된 식기에 세척수를 분사할 수 있게 되며, 헹굼수 분사아암 역시 동일한 구조로 되어 있어 헹굼수가 공급되면 일방향으로 회전하면서 각 분사구멍으로 식기에 헹굼수를 분사할 수 있게 된다.In the dishwasher, the washing water spraying arm rotated and supported by the hollow rotating shaft has a plurality of spraying holes formed at the upper or lower surface thereof, and when the washing water containing the detergent is supplied, the spraying pressure of the washing water is discharged to each spraying hole. It is possible to spray the washing water to the dishes installed in the center of the main body while rotating in one direction through, and the rinsing water injection arm is also the same structure, when the rinsing water is supplied to rotate in one direction to spray rinsing water to the dishes It becomes possible.

한편 상기식기세척기에 있어서는 회전중심축에 결합되는 세척수 분사아암의 회전결합부 상단 및 헹굼수 분사아암의 회전결합부 하단이 마모, 손상되는 것을 방지할 수 있도록 회전중심축의 세척수 분사아암 회전결합부와 헹굼수 분사아암 회전결합부 사이에 마모방지링을 설치하는 예가 많은 바, 회전중심축의 세척수 분사아암 회전결합부와 헹굼수 분사아암 회전결합부 사이에 일측이 절제된 테프론링을 설치하였던 종래에는 일정기간동안 사용하게 되면 테프론링이 마모되면서 세척수 분사아암과 헹굼수 분사아암의 회전이 원활하게 이루어지지 않게 되는 문제가 있었다.On the other hand, in the dishwasher and the washing water injection arm rotary coupling portion of the rotating center shaft to prevent wear and damage of the upper end of the rotary coupling portion of the washing water injection arm coupled to the rotary center shaft and the lower coupling portion of the rinsing water injection arm Many wear prevention rings are installed between the rinsing water injection arm rotary couplings. Thus, the Teflon ring with one side cut off between the washing water injection arm rotary coupling portion and the rinsing water injection arm rotary coupling portion of the rotating center shaft has been conventionally fixed for a certain period of time. When used for a while, the Teflon ring is worn, there was a problem that the rotation of the washing water injection arm and rinsing water injection arm is not made smoothly.

본 고안은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 본체 내부 상부와 내부 하부에 설치되는 회전중심축에 각각 결합되는 세척수 분사아암 및 헹굼수 분사아암의 회전을 보다 원활하게 지지할 수 있도록 하는 식기세척기 분사아암 회전지지구조를 제공하는 데에 있는 것이다.The present invention has been devised in view of the conventional situation as described above, and its purpose is to smoothly support the rotation of the washing water spraying arm and the rinsing water spraying arm, respectively, coupled to the center of rotation installed in the upper and lower portions of the main body. It is to provide a dishwasher spray arm rotation support structure that allows.

본 고안은 상기의 목적을 달성하기 위하여 식기세척기 본체 내부 상부 및 내부 하부에 각각 설치되는 회전중심축의 세척수 분사아암 회전결합부와 헹굼수 분사아암 회전결합부 사이에 내마모성이 좋은 세라믹링을 설치하는 것을 특징으로 하며, 이하 그 구체적인 기술내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.The present invention is to provide a wear-resistant ceramic ring between the washing water spray arm rotary coupling portion and the rinsing water spray arm rotary coupling of the rotary center shaft respectively installed in the upper and lower portions of the dishwasher body to achieve the above object The present invention will be described in more detail based on the accompanying drawings.

즉, 도 1에는 본 고안의 한 실시예가 적용된 식기세척기의 내부 정면도가 도시되어 있고, 도 2에는 동 실시예의 요부 정면도가 도시되어 있으며, 도 3에는 동 실시예의 세라믹링의 사시도가 도시되어 있는 바, 본 고안은 내부 중앙부에 세척할 식기(20)를 투입 설치되는 식기세척기 본체(10)의 내부 상부 및 내부 하부에 회전중심축(50)이 설치되고, 각 회전중심축(50)에 세척수 분사아암(30)과 헹굼수 분사아암(40)이 각각 설치되는 식기세척기(100)에 있어서, 상기 각 회전중심축(50)의 세척수 분사아암 회전결합부(31)와 헹굼수 분사아암 회전결합부(41) 사이에 내마모성이 좋은 세라믹링(60)을 설치하여서 되는 것이다.That is, FIG. 1 shows an internal front view of the dishwasher to which one embodiment of the present invention is applied, FIG. 2 shows a main front view of the embodiment, and FIG. 3 shows a perspective view of the ceramic ring of the embodiment. In the present invention, the rotary center shaft 50 is installed at the upper and lower inner portions of the dishwasher main body 10 in which the dishes 20 to be washed are installed in the inner central portion, and the washing water is sprayed on each of the rotary central shafts 50. In the dishwasher 100, which is provided with the arm 30 and the rinsing water injection arm 40, respectively, the washing water injection arm rotary coupling portion 31 and the rinsing water injection arm rotary coupling portion of the respective rotary center shaft 50 The wear-resistant ceramic ring 60 is provided between the 41 parts.

도면부호중 미설명부호 70은 식기 수납바구니이다.Reference numeral 70 in the drawing denotes a dish storage basket.

상기와 같이 구성된 본 고안에 있어서는 세척수 분사아암(30)나 헹굼수 분사아암(40)이 회전할 때에 그들의 회전결합부(31)(41) 상단 또는 하단에 접촉되는 세라믹링(60)과 마찰되는 것이지만 세라믹링(60)의 내마모성이 우수하게 되므로 세라믹링(60)의 마모로 인하여 각 분사아암(30)(40)의 회전상태가 나빠지게 되는 것을 방지할 수 있게 된다.In the present invention configured as described above, when the washing water spraying arm 30 or the rinsing water spraying arm 40 rotates, it is rubbed with the ceramic ring 60 contacting the upper or lower end of the rotary coupling part 31 and 41. However, since the wear resistance of the ceramic ring 60 is excellent, it is possible to prevent the rotation state of each of the injection arms 30 and 40 from worsening due to the wear of the ceramic ring 60.

이상에서와 같이 본 고안은 회전중심축(50)의 세척수 분사아암 회전결합부(31)와 헹굼수 분사아암 회전결합부(41) 사이에 내마모성이 좋은 세라믹링(60)을 설치한 것으로, 본 고안에 의하면 각 분사아암(30)(40)의 동작과정에서 그들 사이에 설치된 세라믹링(60)의 마모, 손상이 거의 없게 되므로 각 분사아암(30)(40)의 회전을 원활하게 지지할 수 있게 되어 세척수 및 헹굼수의 분사효율 및 식기세척기의 상품성을 크게 향상시킬 수 있게 되는 등의 효과를 얻을 수 있게 된다.As described above, the present invention is to install a good wear resistance ceramic ring 60 between the washing water injection arm rotary coupling portion 31 and the rinsing water injection arm rotary coupling portion 41 of the rotation center shaft 50, According to the present invention, since the wear and damage of the ceramic rings 60 installed therebetween are almost eliminated during the operation of each of the injection arms 30 and 40, the rotation of each of the injection arms 30 and 40 can be smoothly supported. It is possible to obtain an effect such as to greatly improve the spraying efficiency of the washing water and rinsing water and the marketability of the dishwasher.
