Description

물세척 칠판의 물공급장치 {water supply system of water cleaning board}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply system,

본 발명은 물세척 칠판의 물공급장치에 관한 것으로, 더욱 상세하게는 물의 공급을 원활하게 하면서도 세척 효율이 향상되도록 발명된 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device for a water washing board, and more particularly to a water supply device for water washing board.

일반적으로, 칠판표면에 분필로 기재한 기록사항을 소거하기 위하여, 봉제(천)로 된 소거면을 보유하는 칠판지우개를 사용하여 칠판표면을 소거하고 있다.In general, to erase chalk writing on the surface of a blackboard, the blackboard surface is erased using a blackboard eraser that holds the erasable surface of a cloth.

그러나 이러한 칠판지우개로 칠판표면을 문질러서 칠판표면의 기록사항을 소거할 때에는, 분필가루가 주위에 비산하는 문제가 있었다. However, when rubbing the surface of the blackboard with such a blackboard eraser to erase the records on the blackboard surface, there was a problem that the chalk powder scattered around.

또한 칠판지우개의 소거면에 묻어있는 분필가루를 제거하기 위하여 칠판지우개를 털어 낼 때에도 분필가루의 비산 문제가 발생하였다.Also, when chalkboard eraser was wiped off to remove the chalk powder on the erase side of the board eraser, chalk powder scattering problem also occurred.

그런데 칠판표면은 완전한 평면이 아니라 분필의 미끄러짐을 방지하기 위하여 어느 정도의 표면 거칠기를 보유하며, 따라서 그 위에 분필로 글씨를 쓰게 되면 표면의 미세한 오목부에 분필가루가 끼여들어서 빠져 나오지 않게 된다.However, the blackboard surface is not a perfect plane, but rather has some surface roughness to prevent chalk slippage, so if you write on it with chalk, chalk powder will not come out of the fine recesses on the surface.

이러한 이유 때문에 상기 칠판지우개를 사용하여 칠판표면을 지운다고 해도 칠판표면의 기록사항을 깨끗이 지울 수 없는 문제점이 있었다.For this reason, even if the surface of the board is erased by using the board eraser, there is a problem that the recorded matters on the surface of the board can not be cleared.

이러한 문제를 해결하기 위한 흑판류의 소거장치가 일본 공개특허공보 특개평 8-113000호 및 일본 공개특허공보 특개평 9-193599호에 개시되어 있다.In order to solve such a problem, a blackboard erasing apparatus is disclosed in Japanese Patent Application Laid-Open No. 8-113000 and Japanese Patent Application Laid-Open No. 9-193599.

상기 공보에 개시되어 있는 소거장치는, 흑판의 횡방향으로 이동자재한 이동기체에, 브러시, 스펀지 등에 의하여 외주부를 형성한 브러쉬가 흑판 표면측에 그 축심을 흑판의 종방향으로 향하여 탑재됨과 아울러, 그 외주면을 흑판 표면에 슬라이드 접촉시키면서 회전하도록 설계되어 있다. In the erasing apparatus disclosed in the above publication, a brush having an outer peripheral portion formed by a brush, a sponge, or the like is mounted on a moving base movable in the lateral direction of the blackboard, and the brush is mounted on the blackboard surface side with its axial center directed to the longitudinal direction of the blackboard, And is designed so that the outer circumferential surface thereof is rotated while slidingly contacting the black plate surface.

또 이 이동기체에는, 흑판 표면과 브러쉬와의 접촉장소 부근에 물과 같은 세정액을 공급하는 세정액 공급수단이 탑재됨과 아울러 소거부재의 좌우 양측 가운데서 한쪽, 예컨대 좌측에서 흑판 표면에 슬라이드 접촉시킨 상태에서 흑판의 종방향(상하방향)으로 길게 연장시킨 고무재질의 와이퍼부재(스크레이퍼)가 탑재되어 있다.A cleaning liquid supply means for supplying a cleaning liquid such as water to the vicinity of the surface of the black plate and the brush is mounted on the moving substrate. In addition, in the state where the cleaning plate is slidably brought into contact with the surface of the black plate on one side (Scraper) which is elongated in the longitudinal direction (vertical direction) of the wiper member (scraper).

그리고 상기 이동기체에는 와이퍼부재의 좌측에서 흑판 표면에 온풍을 송풍하는 송풍기가 탑재되는 구조가 알려진 바 있다.A structure is known in which a blower for blowing hot air from the left side of the wiper member to the surface of the black plate is mounted on the moving base.

한편, 국내 공개번호 특허 제 1999-013320에서는 판서부재에 크리닝 장치를 좌우 동작시키는 동력장치와 칠판어셈블리에 세정액 공급 조건하에서 브러쉬가 접촉하면서 지움작용을 실시하는 구조가 제안된 바 있다.On the other hand, in Korean Patent No. 1999-013320, there has been proposed a structure in which a brush is brought into contact with a power unit for moving the cleaning device to the left and right on the plunger member and a brush assembly under the condition of supplying the cleaning liquid to the blackboard assembly.

이때 세정액을 공급하기 위하여 물통에서부터 펌프에 의해 공급관을 따라 브러쉬의 상부로 이동시킨 상태에서 브러쉬를 부착하고 있는 중공샤프트의 내부로 강제 급수하여 중공샤프트에 뚫어지는 다수개의 공급구멍을 통해 브러쉬의 지움면으로 세정액을 공급하는 것이다.At this time, in order to supply the cleaning liquid, the water is forced from the water tank to the inside of the hollow shaft attached with the brush while being moved to the upper part of the brush along the supply pipe by the pump, and through the plurality of supply holes drilled in the hollow shaft, To supply the cleaning liquid.

이와 같이, 종래 브러쉬의 상부에서 세정액을 급수하는 경우 상부에서부터 하부까지 세정액 공급량이 일정하지 못하다.As described above, when the cleaning liquid is supplied from the upper portion of the brush, the supply amount of the cleaning liquid from the upper portion to the lower portion is not constant.

따라서, 수압이 비교적 높은 상부에서는 세정액 공급양이 지나치게 많게 되나 하부쪽의 브러쉬로는 세정액 공급양이 부족하여 특히 하부쪽에 판서된 내용은 완전하게 지우지 못하는 경우가 발생되었던 것이다.Therefore, although the amount of the cleaning liquid supplied at the upper portion where the water pressure is relatively high is excessively large, the amount of the cleaning liquid supplied to the lower portion of the brush is insufficient, and the contents written on the lower side are not completely erased.

본 발명은 상기와 같은 문제점을 해소하여 브러쉬의 상부에서 자유 낙하되면서 세정액이 공급되도록 하므로써 고르게 전면에 걸쳐 판서면을 세척할 수 있도록 한 물세척 칠판을 제공하는 데 그 목적이 있다It is an object of the present invention to provide a water washing blackboard which is capable of cleaning a plate writing surface evenly over the entire surface by solving the above problems and supplying the washing liquid while falling freely from the upper portion of the brush

도 1에서는 본 발명에 의한 크리닝칠판을 벽체에 고정시키는 붙박이식 칠판으로 도시하고 있지만 이와는 달리 소정의 스탠드상부에 탑재시켜 이루어지는 이동식칠판으로 하여도 본 발명의 전체적인 구성요부에는 아무런 차이가 없다.1, the cleaning blackboard according to the present invention is shown as a built-in blackboard for fixing the cleaning blackboard to a wall. However, the present invention is not limited to the entire structure of the present invention even if a movable blackboard is mounted on a predetermined stand.

크리닝수단(20)의 좌우 구동은 구동모터(1)의 회전으로 판서부재(11)의 상부 틀체를 따라 설치된 래크에 피니언이 치차 결합된 상태로 구동 방향에 따라 작동되는데, 이는 통상적이므로 상세한 도시나 설명은 생략하기로 한다.The left and right driving of the cleaning means 20 is operated in the driving direction in a state where the pinion is engaged with a rack provided along the upper frame body of the boarder member 11 by the rotation of the driving motor 1, A description thereof will be omitted.

상기 크리닝수단(20)은 세정액탱크(31)로부터 액상의 세정액을 공급하여 세정액이 판서면에 공급되면서 브러쉬(22)의 회전하여 입자(예컨대 분필입자)를 세척하도록 하는 것이다.The cleaning unit 20 supplies a liquid cleaning liquid from the cleaning liquid tank 31 and supplies the cleaning liquid to the plate surface to rotate the brush 22 to clean particles (e.g., chalk particles).

상기 크리닝수단(20)은 모터(M)의 회전으로 샤프트(21)가 회전을 전달받아 샤프트(21)의 외부에 심어진 브러쉬(22)가 판서면에 접촉된 상태로 회전되어 구성된다.The cleaning means 20 is configured such that the brush 21 received on the shaft 21 is rotated by the rotation of the motor M so that the brush 22 is in contact with the plate surface.

그리고, 상기 브러쉬(22)를 감싸는 커버(50) 내측의 양측에는 와이퍼부재(51a)(51b)가 각각 구비되어 구동되는 방향에 따라 브러쉬(22)의 뒤편에서 진행되는 와이퍼부재(51a)가 판서부재(11)와 접촉되면서 세정액을 제거하게 된다.The wiper members 51a and 51b are provided on both sides of the inside of the cover 50 enclosing the brush 22 so that the wiper member 51a running on the rear side of the brush 22, So that the cleaning liquid is removed while being in contact with the member (11).

이때, 타측 와이퍼부재(51b)는 판서부재(11)에 비접촉된 상태를 유지하게 되는데, 이와 같이 와이퍼부재(51a)(51b)가 판서부재(11)의 표면과 접촉 되거나 비접촉하는 작동은 모터(40)의 구동으로 이루어지게 된다.At this time, the other wiper member 51b is kept in a non-contact state with the planer member 11. The operation in which the wiper members 51a and 51b are in contact with or not in contact with the surface of the planer member 11 is performed by the motor 40 as shown in FIG.

한편, 세정액공급수단(30)은 펌프(32)가 세정액탱크(31)내의 세정액을 브러쉬(22)를 가리고 있는 커버(50)의 좌우 양측에 각각 형성된 세정액 이동통로(52)를 향해 강제 급수하는 것에 의해 이루어진다.On the other hand, the rinsing liquid supply means 30 supplies the rinsing liquid in the rinsing liquid tank 31 to the rinsing liquid transfer passage 52 formed on both the left and right sides of the cover 50 covering the brush 22, .

그리고, 공급된 세정액은 다시 세정액탱크(31) 내로 수집되며, 자연 낙하하는 세정액을 모아서 여과시키는 여과수단을 더 구비하면 좋다.The supplied cleaning liquid is collected into the cleaning liquid tank 31 again, and it may be further provided with filtration means for collecting and filtering the cleaning liquid which spontaneously falls.

세정액으로는 상수도물은 물론 증류수, 계면활성수 등의 화학처리수에 이르기까지 세정기능을 가질 수 있는 액체 모두가 포함된다.The cleaning liquid includes not only water, but also any liquid capable of having a cleaning function ranging from chemical water such as distilled water and surface active water.

본 발명에서 가장 중요한 구성상의 특징은 세정액공급수단(30)으로 커버(50)의 좌우 양측에 각각의 세정액 이동통로(52)가 길이방향으로 관통되어 형성되고, 상기 세정액 이동통로(52)의 하단부에는 펌프(32)의 작동시 세정액을 공급하는 이동관(33)이 연결되며, 상기 이동관(33)을 통해 공급이 세정액이 분출되도록 하는 분사공(53)이 세정액 이동통로(52)의 상부 일측에 뚫어져 형성되어 세정액이 브러쉬(22)의 상부에서부터 자유 낙하되도록 구성하는 것이다.The most important structural features of the present invention are that the cleaning liquid supply passage 30 is formed in the left and right sides of the cover 50 so as to penetrate the respective cleaning liquid passage 52 in the longitudinal direction, A transfer pipe 33 for supplying a cleaning liquid is connected during operation of the pump 32 and a spray hole 53 through which the cleaning liquid is supplied through the transfer pipe 33 is provided on one side of the upper portion of the cleaning liquid transfer passage 52 So that the cleaning liquid is freely dropped from the upper portion of the brush 22.

상기 브러쉬(22)를 가리고 있는 커버(50)는 도 2와 도 3에서와 같이 좌우 양측에 각각의 세정액 이동통로(52)가 길이방향으로 관통되어 형성되고, 상기 세정액 이동통로(52)의 상부 일측에는 분사공(53)이 뚫어져 있어, 상기 세정액 이동통로(52)의 하부에 연결된 이동관(33)을 통해 세정액이 소정의 압력으로 공급되면 분사공(53)들을 통해 외부로 분사되는 것이다.As shown in FIGS. 2 and 3, the cover 50 covering the brush 22 is formed with a pair of cleaning fluid passages 52 extending in the longitudinal direction on both left and right sides thereof. The cover 50 covers the upper part of the cleaning fluid passageway 52 And is sprayed to the outside through the spray holes 53 when the washing liquid is supplied through the moving pipe 33 connected to the lower portion of the washing liquid moving passage 52 at a predetermined pressure.

이때, 상기 분사공(53)을 통해 분사되는 세정액은 브러쉬(22)의 가장 상부측에서부터 자유낙하되면서 판서면을 따라 흘러 내리게 되는 것이다.At this time, the cleaning liquid sprayed through the spray hole 53 falls down from the uppermost side of the brush 22 and flows down along the plate surface.

또한, 상기 세정액은 커버(50)와 케이스(25)에 의해 2중으로 보호되어 있으므로 외부로 유출되지 않게 되므로 브러쉬 상부로 공급된 대부분이 판서부재(11)의 표면을 따라 하강되어 다시 세정액탱크(31)로 수집되는 것이며, 이 세정액 공급과 동시에 상기한 바와 같이 브러쉬(22)가 판서면에 접촉된 상태로 이동하면서 빠르게 회전하는 것에 의해 분필 입자를 깨끗하게 지울 수가 있는 것이다.In addition, since the cleaning liquid is doubly protected by the cover 50 and the case 25, most of the liquid supplied to the upper portion of the brush is lowered along the surface of the plunger member 11, As described above, the brush 22 is rotated while moving in contact with the plate surface, so that the chalk particles can be cleanly removed.
