The present invention relates to an automatic water exchange treatment apparatus for a water tank in which manual exchange is performed through automatic exchange.

종래의 정수기장치는 원수로 부터 불순물이 제거되는 정수필터와 급수를 제공하는 솔레노이드밸브의 급수량을 신속하고 많은 양을 전달되도록 하는 펌프에 의해 공급된 물을 저장하는 물 탱크로 구성되어 있다.Conventional water purifier device is composed of a water tank for storing the water supplied by the water filter to remove the impurities from the raw water and the pump to ensure that the water supply of the solenoid valve for supplying water is delivered quickly and large amounts.

이러한 종래의 정수장치의 작용은 원수가 정수필터로 통해 사람이 먹어서는 안 될 중금속이나 모래 등의 유해물질을 사전에 배출되지 못하도록 걸러주게 되며, 이것이 솔레노이드밸브로 부터 급수의 양이 조절된다. 이렇게 조절된 급수량은 모터의 구동으로 신속하게 많은 급수를 물 탱크에 제공하게 된다.The action of the conventional water purifier is to filter the raw water through the water filter to prevent harmful substances such as heavy metals or sand that should not be eaten in advance, and the amount of water supplied from the solenoid valve is controlled. This regulated water supply speeds up the supply of water to the water tank.

이와 작용하는 종래의 정수장치는 물탱크에 있는 물을 오랜 기간동안 사용을 하지 않으면 물이 변질되고 물이 변질된 상태 즉 오염된 상태 그대로 방치하면 결국 물을 버리게 된다.In the conventional water purifier that works on this, if the water in the water tank is not used for a long time, the water is deteriorated and the water is left in the deteriorated state, that is, the contaminated state.

또한, 물 저장 탱크에 얼마동안 저장되었는지 알기 어려워 버리는 시기를 놓치거나 미리 버리는 문제점이 있었다.In addition, it is difficult to know how long it has been stored in the water storage tank, there is a problem missing or missed in advance.

이와 같은 종래의 제반 문제점을 해결하기 위한 본 발명의 목적은 물 저장시간을 마이컴에서 계산하여 일정시간이 지나면 폐수로를 통해 배출되게 하며 솔레노이드를 통한 자연압에 의한 배출과정과 펌프모터를 사용하여 강제 배출되는 방식으로 정수된 물이 오랜 기간동안 고여 있어 변질된 오염 식수를 자동으로 폐수처리되고 다시 정수된 식수를 물 탱크에 저장되게 하여 오염식수를 먹지 않도록 하는 것에 있다.The purpose of the present invention for solving the conventional problems as described above is to calculate the water storage time in the microcomputer to be discharged through the waste water channel after a certain time and forced discharge by the natural pressure through the solenoid and the pump motor The purified water is discharged in a long period of time so that the contaminated drinking water is automatically treated as wastewater and the purified water is stored in the water tank so as not to eat the contaminated drinking water.

이하 첨부된 도면에 의해 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

제1도에서 보는 바와 같이 자동수교환 처리장치를 나타내는 본 발명은 원수(D)의 상태가 식수로 가능하게 불순물을 제거되는 정수필터(F)를 통해 들어오는 급수가 제공되게 하는 솔레노이드밸브(J)와 정수펌프(P)를 거치며 유출되는 급수를 저장하기 위한 정수물탱크(T)에 수위상태를 점검하는 수위감지센서(S)와 정수물탱크(T) 안에 물이 만수여부가 감지되는 만수감지스위치(H)를 구비하고, 정수물탱크(T)로 부터 유출된 물이 급수솔레노이드밸브(G)를 통해 급수를 얻을 수 있고 지정한 시간 경과가 되면 폐수를 유출 가능한 폐수솔레노이드밸브(L)로 구성되어 있으며, 특히 시간을 카운터되는 마이컴부(M)와 사용자가 임의의 시간을 설정가능하도록 하는 입력부(I)와 각 밸브 또는 펌프에 회선이 연결되어 정수 또는 폐수가 자동으로 제어되게 작동하는 컨트롤부(C)를 갖춘 컨트롤기판(CP)로 구성된 것을 특징으로 한다.As shown in FIG. 1, the present invention, which shows an automatic water exchange treatment apparatus, provides a solenoid valve (J) for supplying water supplied through a water filter (F) in which the state of raw water (D) is capable of removing impurities into drinking water. Water level sensor (S) to check the water level in the purified water tank (T) for storing the water supply flowing through the purified water pump (P) and the full water detection to detect whether the water is full in the purified water tank (T) It is equipped with a switch (H), the water flowing out from the purified water tank (T) can be supplied to the water supply through the water supply solenoid valve (G) and consists of a waste water solenoid valve (L) that can discharge the waste water when the specified time elapses In particular, the microcomputer unit (M) that counts the time, the input unit (I) that allows the user to set an arbitrary time, and the line is connected to each valve or pump control to operate the water or waste water automatically controlled The unit consisting of the control board (CP) with (C) is characterized.

이와 같이 구성된 본 발명의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above in detail.

제1도에서 보는 바와 같이 자동수교환 처리장치를 나타내는 본 발명은 정수기의 컨트롤기판(CP)에 있는 입력부(I)에서 정수의 명령이 내려져 입력이 되면 마이컴부(M)에서 이를 감지하고난 후 컨트롤부(C)는 정수솔레노이드밸브(F)를 개방하여 급수의 수로를 열어주며 정수 펌프(P)를 온(on)하게 되어 정수된 물을 정수물탱크(T)에 저장하게 된다.As shown in FIG. 1, the present invention showing an automatic water exchange processing apparatus is provided with a command of an integer from the input unit I on the control board CP of the water purifier, and when the input is input, the microcomputer unit M detects it. The control unit C opens the purified water solenoid valve F to open the water supply channel, and turns on the purified water pump P to store purified water in the purified water tank T.

정수물탱크(T)안에 물이 차게 되면 수위감지센서(S)가 저수위와 고수위를 감지하게 되어 현재 수위상태를 감시하게 된다. 또한, 고수위되어 만수가 되면 만수위감지스위치(H)가 이것을 감지하게 되어 감지 신호를 마이컴부(M)에 전달하게 된다.When the water is filled in the purified water tank (T), the water level sensor (S) detects the low and high water levels to monitor the current water level. In addition, when the high water level is full, the high water level detection switch (H) detects this and transmits a detection signal to the microcomputer unit (M).

상기의 마이컴(M)은 만수감지스위치(H)로 부터 만수신호를 받아 정수솔레노이드밸브(J)와 정수펌프(P)를 정지시켜 물탱크에 급수공급을 중단하게 된다. 이와 같이 중단된 급수로부터 마이컴(M)은 시간 카운트를 시작하게 되는데 시간 카운터진행중 사용자가 입력부(I)의 취수스위치를 투르게 되면 급수솔레노이드밸브(G)가 동작하여 물탱크의 물을 급수하게 되어 정수물탱크(T) 내부의 물이 수위가 낮아지면 만수감지스위치(H)가 마이컴부(M)으로 신호를 전달하게 된다. 만수감지스위치(H)로 부터 저수위신호를 전달 받은 마이컴부(M)은 다시 정수명령을 내리게 되고 시간카운터는 리셋되어 카운터를 중지시키게 된다.The microcomputer (M) receives the water level signal from the water level detection switch (H) to stop the water purification solenoid valve (J) and the water pump (P) to stop the water supply to the water tank. In this way, the microcomputer (M) starts the time counting from the stopped water supply. When the user switches the water intake switch of the input unit (I) during the time counter, the water supply solenoid valve (G) operates to supply water from the water tank. When the water level in the purified water tank (T) is lowered, the full water detection switch (H) transmits a signal to the microcomputer (M). The microcomputer unit M, which has received the low water level signal from the full water detection switch H, issues an integer command again, and the time counter is reset to stop the counter.

또한, 시간카운터가 임의의 시간 즉 사용자가 입력회로를 통해 주위환경을 고려하여 설정한 시간이 되면, 폐수솔레노이드밸브(L)가 마이컴부(M)으로 부터 작동되어 물탱크의 물을 버리게 되고 물이 폐수되는 자연압에 의한 배출방법과 펌프모터를 사용하여 강제 배출하는 방법 등을 사용하여 다시 정수를 시작하게 되므로 처음의 과정을 반복실행하게 된다.In addition, when the time counter reaches an arbitrary time, that is, a time set by the user in consideration of the surrounding environment through the input circuit, the wastewater solenoid valve L is operated from the microcomputer unit M to discard the water in the water tank. Water purification is started again using the discharge method by the natural pressure discharged by the wastewater and the forced discharge using the pump motor, and so the first process is repeated.

제2도에서 보는 바와 같이 자동수교환 처리장치의 폐수과정의 흐름도를 나타내는 본 발명은 정수물탱크(T)의 만수상태를 감지한 만수감지스위치(H)로 부터 만수신호를 전송받게 되는 마이컴부(M)은 시간 카운터를 시작(10)하게 된다.As shown in FIG. 2, the present invention showing a flow chart of a wastewater process of an automatic water exchange treatment apparatus includes a microcomputer unit receiving a water level signal from a water level detection switch H that detects the water level of the purified water tank T. FIG. M starts the time counter 10.

상기의 카운터시작(10)으로 부터 정수펌프(P)가 동작정지(20)되었는지 그 여부에 따라 폐수카운터(30)를 시작한다. 폐수카운터(30)는 카운터하여 급수솔레노이드의 동작상태(40)의 여부로 동작상태(40)에 있으면 폐수카운터를 리셋(50)하게 되어 원래의 상태인 마이컴카운터 재시작(10)으로 되돌아가게 되고 급수솔레노이드동작상태(40)이 없으면 폐수카운터 일정시간도달(60) 여부를 묻게 된다.The wastewater counter 30 is started from the counter start 10 according to whether the purified water pump P is stopped 20. The wastewater counter 30 counters and resets the wastewater counter 50 if it is in the operating state 40, whether or not the water supply solenoid is in the operating state 40, and returns to the original state of the microcomputer counter restart 10. If there is no solenoid operation state 40, the waste water counter is asked whether the predetermined time reaches (60).

상기의 일정시간도달(60)이 완료되면 폐수펌프 및 솔레노이드밸브가 개방(70)되어 전제 동작 수행이 완료(80)되고, 폐수카운터 일정시간(60)이 완료되지 못하면 폐수카운터(30)를 다시하게 된다.When the predetermined time reaches 60, the wastewater pump and the solenoid valve are opened (70) to complete the preliminary operation, and the wastewater counter (30) is not completed when the wastewater counter (30) is not completed. Done.

이와 같이 작용하는 본 발명의 자동수교환 처리장치는 정수기의 사용하고 있는 물을 일정시간이 지나면 오염이 되었기 때문에 폐수로 버려야 되며 사용하고 있는 주위 환경에 따라 물의 2차적 오염시간이 차이가 나게 되어 물을 폐수하는 시간이 각기 다르게 된다. 따라서 사용자의 주위환경에 따라 각기 다르게 그 시간을 입력하여 사용할 수 있도록 오염된 물을 식수로 마시는 일이 없도록 자동으로 수교환이 되어 항상 깨끗하고 안심하고 물을 마실수 있는 효과를 제공받는 신규발명이다.The automatic water exchange treatment device of the present invention that acts as described above should be discarded as waste water because the water used in the water purifier has been contaminated after a certain time, and the secondary pollution time of the water will be different depending on the surrounding environment. The time to waste water is different. Therefore, according to the user's surrounding environment, it is a new invention that the water is automatically exchanged so that the contaminated water is not drunk with drinking water so that it can be used by entering the time differently, so that the effect of drinking water is always clean and safe.
