Description
본 고안은 정수기의 내부에 설치되어 정수되는 물을 자외선에 의하여 살균하는 살균 유니트에 관한 것으로서, 보다 상세하게는 정수기내에서 처리되는 모든 물에 대하여 자외선을 균일하고 일정시간 조사함으로써 살균효율을 크게 증가시키고 살균효과를 균일하게 하는 정수기물 살균 유니트에 관한 것이다.The present invention relates to a sterilization unit for disinfecting water purified by ultraviolet rays installed inside the water purifier. More specifically, sterilization efficiency is greatly increased by irradiating ultraviolet light uniformly and for a predetermined time to all water treated in the water purifier. The present invention relates to a water purifying sterilization unit which makes the sterilization effect uniform.
일반적으로 정수기내에는 정수되는 물에 함유되어 있는 대장균, 포도상 구균 등 각종 균을 살균하기 위한 살균 유니트가 설치되어 있다.Generally, a sterilization unit is installed in the water purifier to sterilize various bacteria such as E. coli and staphylococci contained in the purified water.
종래의 살균 유니트는 도 1 및 도 2에 도시되어 있는 바와 같이 중심부에서 자외선을 조사하는 자외선램프(1), 상기 자외선 램프(1)의 주위에 설치된 석영관(2), 상기 석영관(2)의 주위에 설치된 것으로서 살균되는 물이 들어가고 나가는 입구(3a)와 출구(3b)가 구비되어 있는 외부커버(3), 그리고 상기 석영관(2)을 설치하는 고정대(4)로 구성되어 있다.The conventional sterilization unit is an ultraviolet lamp (1) for irradiating ultraviolet rays from the center as shown in Figs. 1 and 2, a quartz tube (2) installed around the ultraviolet lamp (1), the quartz tube (2) It is composed of an inlet (3a) and an outlet (3b) having an inlet (3a) for entering and exiting the sterilized water, and a fixing stand (4) for installing the quartz tube (2).
상기 석영관(2)은 자외선투과효율이 높은 석영재질로 되어 있으며 자외선 램프(1)의 주위에 설치하여 자외선램프(1)와 물을 분리함과 동시에 자외선을 효율적으로 투과하여 물에 조사하기 위하여 설치된 것이다. 석영관(2)의 내부에는 자외선램프(1)가 설치되는 배치되는데 단순히 램프의 단자를 연결하는 전선에 의하여 지지될 뿐 아무런 지지수단은 구비되어 있지 않다.The quartz tube 2 is made of quartz material having high UV transmission efficiency and is installed around the UV lamp 1 to separate the UV lamp 1 and water and to transmit UV light efficiently to irradiate water. It is installed. Inside the quartz tube 2, the ultraviolet lamp 1 is arranged to be installed, which is simply supported by an electric wire connecting the terminals of the lamp, and no supporting means is provided.
외부커버(3)는 스테인레스재질로 되어 있고, 고정대(4)는 PC 와 같은 합성수지재질로 되어 있다. 그리고 석영관(2)과 외부커버(3)는 원통형으로 되어 있다.The outer cover 3 is made of stainless steel, and the holder 4 is made of synthetic resin such as PC. The quartz tube 2 and the outer cover 3 are cylindrical.
정수되는 물은 외부커버(3)의 입구(3a)로 들어와서 석영관(2)과 외부커버(3)사이를 통과하면서 자외선램프(1)에서 조사되는 자외선에 의하여 살균된 후 출구(3b)를 통하여 외부로 빠져나간다.The purified water enters the inlet 3a of the outer cover 3, passes through the quartz tube 2 and the outer cover 3, and is sterilized by ultraviolet rays irradiated from the ultraviolet lamp 1, and then the outlet 3b. Exit out through.
그러나 상기와 같은 종래의 정수기물 살균 유니트는 물이 석영관(2)과 외부커버(3)사이를 통과할 때에 석영관(2)의 주위를 골고루 순환하지 못할 뿐만 아니라 석영관(2)과 외부커버(3)사이에 머무르는 시간도 일정하지 못하다. 즉 물이 흐르는 통로는 그 단면이 환형으로 되어 있고 입구(3a)와 출구(3b)는 그 통로의 일측에 구성되어 있어서 유입된 물의 일부는 외부커버(3)의 입구(3a)에서 출구(3b)쪽으로 바로 흐르고 일부의 물은 석영관(2)과 외부커버(3)사이의 하부쪽에 오래 머무른다. 따라서 모든 물이 자외선에 조사되는 시간이 균일하지 못하여 살균효과가 균일하지 못할 뿐 아니라 일부 물은 충분히 살균되기도 전에 유니트로부터 빠져 나오게 되는 문제점이 있다.However, the conventional water purifier sterilization unit as described above not only does not circulate evenly around the quartz tube 2 when water passes between the quartz tube 2 and the outer cover 3, but also the quartz tube 2 and the outside. The time of stay between the covers 3 is also not constant. That is, the passage through which the water flows has an annular cross section, and the inlet 3a and the outlet 3b are configured at one side of the passage so that a part of the inflowed water is discharged from the inlet 3a of the outer cover 3 to the outlet 3b. The water flows straight toward) and some water stays on the lower side between the quartz tube 2 and the outer cover 3 for a long time. Therefore, the time that all the water is irradiated with ultraviolet light is not uniform, the sterilization effect is not uniform, and there is a problem that some water is released from the unit before being sufficiently sterilized.
그리고 석영관(2)은 고정대(4)에 고정되는데 물이 흐름에 따라 충격을 받아 그 고정부분에서 파괴되어 물이 자외선램프(1)에 접속하게 하는 문제점도 있다.In addition, the quartz tube 2 is fixed to the fixing stand 4, but there is a problem that the water is shocked as it flows and is destroyed at the fixing part so that the water is connected to the ultraviolet lamp 1.
본 고안은 전술한 종래 기술의 문제점을 해소하기 위하여 안출된 것으로서, 정수기내에서 처리되는 모든 물에 대하여 자외선을 균일하게 그리고 일정시간 조사함으로써 살균효율을 크게 증가시키고 살균효과를 균일하게 하는 정수기물 살균 유니트를 제공하는 것을 그 목적으로 하고 있다.The present invention was devised to solve the above-mentioned problems of the prior art. Water purifier sterilization which greatly increases sterilization efficiency and uniform sterilization effect by irradiating UV light uniformly and for a certain time on all water treated in the water purifier. The purpose is to provide a unit.
상기 목적을 달성하기 위한 본 고안의 정수기물 살균 유니트는 자외선 램프를 이용한 정수기물 살균 유니트에 있어서, 상기 자외선 램프의 주위에 배치되어있으며 입구와 출구가 구비되어 물이 나선형으로 흐르도록 된 코일형 관, 그리고 상기 코일형 관을 감싸며 자외선을 반사하는 재질로 된 상부커버와 하부커버를 포함하는 것을 특징으로 한다.Water purifier sterilization unit of the present invention for achieving the above object is a water purifier sterilization unit using an ultraviolet lamp, which is disposed around the ultraviolet lamp and is provided with an inlet and an outlet so that the water flows spirally And an upper cover and a lower cover made of a material surrounding the coiled tube and reflecting ultraviolet rays.

도시된 바와 같이 본 고안의 정수기물 살균 유니트는 자외선 램프(1)의 주위에 배치되어 있으며 입구(10a)와 출구(10b)가 구비되어 물이 흐르도록 된 코일형 관(10), 그리고 상기 코일형 관(10)을 감싸며 자외선을 반사하는 재질로 된 상부커버(11)와 하부커버(12)를 포함한다.As shown, the water purifying water sterilization unit of the present invention is disposed around the ultraviolet lamp 1 and is provided with an inlet 10a and an outlet 10b and a coiled tube 10 through which water flows, and the coil An upper cover 11 and a lower cover 12 are formed of a material surrounding the mold tube 10 and reflecting ultraviolet rays.
상기 코일형 관(10)의 재질은 석영과 같이 자외선 투과효율이 좋은 것을 이용한다.The material of the coiled tube 10 uses a good ultraviolet transmission efficiency, such as quartz.
상기 상부커버(11)와 하부커버(12)는 그 접촉면에 각각 홈(11a)과 돌기(12a)가 형성되어 있으며, 상부커버(11)에는 코일형 관(10)의 입구(10a)와 출구(10b)가 각각 관통하는 관통공(11b)이 형성되어 있다. 상부커버(11)와 하부커버(12)는 각각 알루미늄과 같이 자외선이 잘 반사되는 재질로 되어 있다.The upper cover 11 and the lower cover 12 are formed with grooves 11a and protrusions 12a on their contact surfaces, respectively, and the upper cover 11 has an inlet 10a and an outlet of the coiled tube 10. Through-holes 11b through which 10b each pass are formed. The upper cover 11 and the lower cover 12 are made of a material in which ultraviolet rays are well reflected, such as aluminum.
상기 상부커버(11)와 하부커버(12)의 양측에는 각각 캡(13)(13')이 고정되어 있으며, 일측의 캡(13)에는 전원 케이블(14)이 관통하는 관통공이 형성되어 있다.상기 캡(13)(13')은 상부커버(11)와 하부커버(12)를 서로 결합하기 위하여 약간의 탄성을 갖는 합성수지재로 형성하는 것이 바람직하다.Caps 13 and 13 ′ are fixed to both sides of the upper cover 11 and the lower cover 12, respectively, and through-holes through which the power cable 14 penetrates are formed in the cap 13 on one side. The caps 13 and 13 'are preferably formed of a synthetic resin material having a slight elasticity in order to couple the upper cover 11 and the lower cover 12 to each other.
자외선 램프(1)의 동작에 필요한 회로를 구비한 램프 PCB(15)에는 전원 케이블(14)이 연결되어 있으며, 초생달형상으로 형성되어 자외선 램프(1) 주위의 적절한 공간에 배치된다.The power cable 14 is connected to a lamp PCB 15 having a circuit necessary for the operation of the ultraviolet lamp 1 and is formed in a crescent shape and disposed in an appropriate space around the ultraviolet lamp 1.
상기와 같이 구성된 본 고안의 정수기물 살균 유니트는 다음과 같이 작용한다.Water purifier sterilization unit of the present invention configured as described above acts as follows.
정수기내에서 정수되는 물은 코일형 관(10)의 입구(10a)로 들어가서 코일형 관(10)을 따라 나선형으로 흐른 후 출구(10b)로 나온다. 이 때 자외선 램프(1)에서는 자외선을 조사하고 있고 코일형 관(10)은 자외선 투과효율이 좋은 재질로 되어 있으므로 코일형 관(10)을 통과하고 있는 물에 자외선이 투과하고 코일형 관(10) 및 물을 통과한 일부의 자외선은 상부커버(11)와 하부커버(12)의 내면에서 반사되어 다시 코일형 관(10)내부로 들어가서 물을 투과한다.The water purified in the water purifier enters the inlet 10a of the coiled tube 10, flows spirally along the coiled tube 10, and then exits the outlet 10b. At this time, the ultraviolet lamp 1 is irradiated with ultraviolet rays, and the coiled tube 10 is made of a material having good ultraviolet transmission efficiency. Thus, ultraviolet rays are transmitted to the water passing through the coiled tube 10 and the coiled tube 10 And some ultraviolet rays passing through the water are reflected from the inner surfaces of the upper cover 11 and the lower cover 12 to enter the coiled tube 10 and penetrate the water.
상기와 같이 물은 코일형 관(10)을 통과하므로 모든 물이 코일형 관(10)에 머무르는 시간이 일정하고 균일하게 조사된다. 그리고 자외선은 자외선 램프(1)에서 조사되면서 일차적으로 물을 투과하고 상부커버(11)와 하부커버(12)에 의하여 반사되어 이차적으로 물을 투과한다. 따라서 모든 물에 대한 살균효과가 탁월할 뿐만 아니라 균일하게 된다.As described above, since water passes through the coiled tube 10, the time for all the water to stay in the coiled tube 10 is uniformly and uniformly irradiated. In addition, ultraviolet rays are primarily transmitted through the UV lamp 1 and are reflected by the upper cover 11 and the lower cover 12 to secondly penetrate the water. Therefore, the sterilizing effect on all waters is excellent and uniform.
이와 같이 본 고안의 정수기물 살균 유니트는 정수기내에서 처리되는 모든물에 대하여 자외선을 균일하게 그리고 일정시간 조사함으로써 살균효율을 크게 증가시키고 살균효과를 균일하게 하는 효과를 발휘한다.As described above, the water purifier sterilization unit of the present invention exhibits an effect of greatly increasing sterilization efficiency and uniform sterilization effect by irradiating UV light uniformly and for a predetermined time to all the water treated in the water purifier.
