전기(분해식) 냉.온 정수기{Hot and cold water purifier using electrolysis}Hot and cold water purifier using electrolysis

본 발명은 수도 직결식으로 설치되어지는 냉.온 정수기에 관한 것으로, 특히정수부와 1, 2차 전해부에 의한 전기(분해식) 정수방식이 사용되고, 이 방식에 의하여 생성되는 3가지 전해이온수(강알칼리수, 약알칼리수, 산성수)의 용도별 집수가 용이하게 한 것이 특징이다.The present invention relates to a cold and hot water purifier installed directly connected to the water, in particular, the electrolytic (decomposition) water purification method by the water purification unit and the primary and secondary electrolytic unit is used, and three electrolytic ion water produced by this method ( Strong alkali water, weak alkaline water, acidic water) is characterized by the ease of collection by use.

종래에 전기분해 방식의 냉.온 정수기를 공급하기 위해서는 통상의 냉.온 정수기에 전기분해장치를 별도로 설치하여 정수부와 전해부의 이원화에 의한 설치가 불편한 문제점이 있었고, 또한 전해부로부터 생성되는 전해이온수 중 몸체에 이로운 "활성수소"가 풍부하게 함유된 약알칼리수의 안정적인 생성이 어려웠던 문제점이 있었다.Conventionally, in order to supply an electrolytic cold / hot water purifier, an electrolysis device is separately installed in a normal cold / hot water purifier, and installation of the purified water part and the electrolytic part is inconvenient, and electrolytic ion water generated from the electrolytic part There was a problem in that stable generation of weak alkaline water rich in "active hydrogen" beneficial to the body was difficult.

따라서 상기한 문제점의 해결을 위하여 본원발명의 출원인은 정수부와 전해부가 내장토록 하되 전해부는 1차 전해부와 2차 전해부로 구분토록 하여 유입수를 우선 1차 전해부를 통하여 전기분해시켜 알칼리수와 산성수로 생성토록 한 후, 생성된 알칼리수만을 2차 전해부를 통하여 한 번 더 전기분해시켜 pH 7.4∼8.5급의 약알칼리성수를 생성시켜 식수로 사용토록 함과 동시에 부차적으로 생성되는 강알칼리수와 산성수까지도 각각 세척, 세안용으로 사용이 가능토록 한 정수방식의 정수기를 출원번호 제10-2001-0068157호로서 선출한 바 있다.Therefore, in order to solve the above problems, the applicant of the present invention allows the purified water part and the electrolytic part to be built in, but the electrolytic part is divided into the primary electrolytic part and the secondary electrolytic part. After generation, only alkaline water produced is electrolyzed once more through the secondary electrolytic unit to generate weak alkaline water of pH 7.4-8.5, and used as drinking water, and also strong alkali water and acidic water that are generated secondaryly.

There is a problem in that it is not easy to use by efficient use due to the inconvenience of collecting by use according to the component of the ionized water.

The acidic water electrolyzed once more and generated in the (+) electrode chamber 23 of the secondary electrode chamber is discharged by joining the acidic water discharge hose 30 and discharged from the (-) electrode chamber 24. The generated strong alkaline water is discharged through the strong alkaline water discharge hose 40, and the weak alkaline water generated in the negative electrode chamber 25 is passed through the post-treatment filter unit 60, 60a. After the treatment is made of a structure of the water purification system to discharge through the weak alkaline water discharge hose 50, the acidic water discharge hose 30 and the strong alkaline water discharge hose 40 by the integrated circuit in a predetermined time period of the mutual discharge direction The switching control solenoid valves 31 and 41 are respectively installed so that the electrolytic ion water of the same component is always introduced into the acidic water collecting tank 32 and the strong alkali collecting tank 42, and the weak alkaline water discharge hose 50 is provided at a predetermined time interval. The wastewater discharge control solenoid valve 51 to the wastewater discharge hose 50a is installed to flow into the drinking water reservoir 70 provided with the hot water tank 71 and the cold water tank 72.

이때 상기 전해부(10)에는 각각의 전극실(21)(22)(23)(24)(25) 형성을 위한 전극판(26)과 물 속의 이온만이 이동토록 하기 위한 이온분리격막(27)이 장착되어지는 것이고, 장착된 전극판(26)에는 전압분배기(29)에 의하여 (+) 또는 (-) 전극이 형성되게 되고, 전극판(26)의 청소를 위하여 시간기억 집적회로에 의하여 정수기 사용시간을 일정시간 주기로 자동 제어토록 하여 자동청소동작이 이루어지도록 되어 있는 것으로 이 청소동작은 전극판(26)의 극성 전환에 의하여 이루어지는 것이다.In this case, the electrode plate 26 for forming each of the electrode chambers 21, 22, 23, 24, and 25 and the ion separation membrane 27 for allowing only ions in the water to move in the electrolytic unit 10. (+) Or (-) electrodes are formed on the mounted electrode plate 26 by the voltage divider 29, and the time memory integrated circuit is used for cleaning the electrode plate 26. The automatic cleaning operation is performed by automatically controlling the water purifier use time at a predetermined time period, and the cleaning operation is performed by changing the polarity of the electrode plate 26.

또한 상기 후처리필터부(60)의 후단에는 은활성탄필터를 비롯한 각종 고기능성 필터를 장착시킨 추가 후처리필터부(60a)를 형성시킬 수 있는 것이다.In addition, at the rear end of the aftertreatment filter unit 60, an additional aftertreatment filter unit 60a equipped with various high functional filters including a silver activated carbon filter may be formed.
