본 발명은 정수기의 급수장치에 관한 것으로 특히 역삼투막방식 정수기의 급수감지장치로서 단수시나 수도콕을 잠구어 놓은 상태에서 동작시킬 경우 급수밸브와 펌프의 공운전에 의한 손상이나 전력낭비를 방지하도록한 것이다.The present invention relates to a water supply device for a water purifier, and in particular, as a water supply detection device for a reverse osmosis membrane type water purifier to prevent damage or waste of power due to co-operation of a water supply valve and a pump when water is operated when water is shut off or when the water cock is locked. .
종래의 정수기는 제 1 도와 같이 수도콕과 급수호스(1')로 연결되어 전기적으로 개폐되는 급수밸브(1)와 상기 급수밸브(1)를 통하여 유입된 물속의 각종 입자를 가진 이물질을 제거하는 전처리필터(2)와 상기 전처리필터(2)를 거친 물의 소독을 위해 들어 있는 염소를 제거하기 위한 활성탄으로 충진된 후처리필터(3)와 상기 후처리 필터(3)를 통과한 물을 가압시키는 펌프(4)와 상기 펌프(4)에 의하여 펌핑된 물을 분리 여과하는 역삼투막(5)과 상기 역삼투막(5)을 통과한 여과수가 통과하는 여과수라인(6)과 상기 여과수라인(6)과 병렬로 구성되어 여과된 물을 보관하는 압력저장탱크(8)와 상기 압력저장탱크(8)의 수위에 따라 발생되는 압력에 의하여 펌프(4)의 동작을 제어하는 압력스위치(10)와 상기 여과수라인(6)의 선단에는 여과된 정수를 취출하는 취출콕(9)이 구성되고 상기 역삼투막(5)에서 농축된 오염물질이 배출되는 농축수라인(7)이 구성되었다.The conventional water purifier removes foreign substances having various particles in the water introduced through the water supply valve 1 and the water supply valve 1 which are electrically connected to the water cock and the water supply hose 1 'like the first diagram. To pressurize the water passed through the aftertreatment filter 3 and the aftertreatment filter 3 filled with activated carbon for removing chlorine contained in the pretreatment filter 2 and the pretreatment filter 2 for disinfection of water. The reverse osmosis membrane 5 for separating and filtering the pump 4 and the water pumped by the pump 4, and the filtered water line 6 through which the filtered water passing through the reverse osmosis membrane 5 passes and the filtered water line 6 in parallel. Composed of a pressure storage tank (8) for storing the filtered water and the pressure switch (10) for controlling the operation of the pump (4) by the pressure generated in accordance with the water level of the pressure storage tank (8) and the filtered water line At the tip of (6), the takeout cock (9) for taking out the filtered purified water Constructed and concentrated water which is contaminated material concentrated in the reverse osmosis membrane (5) a discharge line (7) is comprised.
이와 같이 구성된 정수기에서 정수된 물이 압력저장탱크(8)에 없을때 수도물을 정수하기 위하여 수도콕을 개방하고 전원은 인가하면 압력저장탱크(8)내에 여과된 물이 없기 때문에 압력스위치(1)의 접점이 연결되어 급수밸브(1)와 펌프(4)이 전원이 인가된다.When the purified water in the water purifier configured in this way is not in the pressure storage tank 8, the water cock is opened to purify the tap water, and when the power is applied, since there is no filtered water in the pressure storage tank 8, the pressure switch 1 The contact of is connected to the water supply valve (1) and the pump (4) is powered.
따라서 급수밸브(1)가 개방되고 펌프(4)가 가동되기 때문에 수도콕의 수도물이 급수밸브(1)를 거쳐 전처리 필터(2)를 지니는 과정에서 물속의 각종입자를 가진 이물질을 제거한다.Therefore, since the water supply valve 1 is opened and the pump 4 is operated, foreign substances having various particles in the water are removed in the course of having the pretreatment filter 2 through the water supply valve 1.
이와 같이 이물질이 제거된 물은 후처리필터(3)에 유입되어 통과하면서 물속의 각종 불순물과 염소가 제거되면서 펌프(4)에 의하여 5kg/㎠ 수압으로 역삼투막(5)으로 압송된다.As such, the water from which foreign matters are removed is introduced into the aftertreatment filter 3, and various impurities and chlorine in the water are removed and pumped to the reverse osmosis membrane 5 at a pressure of 5 kg / cm 2 by the pump 4.
이때 역삼투막(5)으로 압송되어 통과하면서 물속의 각종 오염물질이 분리되어 오염물질은 농축되어 농축수라인(7)을 따라 배출된다.At this time, various contaminants in the water are separated while being pumped through the reverse osmosis membrane (5), the contaminants are concentrated and discharged along the concentrated water line (7).
이와 같이 역삼투막(5)에 의하여 여과된 여과수는 압력스위치(10)를 거쳐 압력저장탱크(8)에 저장되면서 시간이 어느 정도 경과하면 압력저장탱크(8)내에 들어있는 공기가 유입된 여과수 양만큼 압축되어 여과수라인(6)에 압력이 걸리게 되고 이때 압력스위치(10)에 설정된 차단압력 이상이 되면 압력스위치(10)의 접점이 떨어지게 되어 급수밸브(1)와 펌프(4)의 전원을 차단시켜 급수가 중지된다.The filtered water filtered by the reverse osmosis membrane 5 is stored in the pressure storage tank 8 via the pressure switch 10, and when a certain time elapses, the amount of filtered water introduced into the pressure storage tank 8 flows in. When the pressure is applied to the filtrate water line 6 when the pressure is greater than the cutoff pressure set in the pressure switch 10, the contact point of the pressure switch 10 is dropped to cut off the power supply of the water supply valve 1 and the pump 4. Watering stops
이와 같이 압력저장탱크(8)에 여과되어 저장된 정수를 사용키 위해 취출콕(9)을 개방시켜 정수를 사용하면 여과수라인(6)내에 걸려있는 압력이 낮아지면서 압력스위치(10)에 설정된 동작압력이하로 되면 전술한 바와 같이 압력스위치(100)의 접점이 연결되어 급수밸브(1)와 폄프(4)에 전원을 인가하여 초기와 같이 급수가 이루어짐과 더불어 여과수가 압력저장탱크(8)에 저장되는 것이다.In this way, when the extraction cock 9 is opened to use the purified water filtered and stored in the pressure storage tank 8, and the purified water is used, the operating pressure set in the pressure switch 10 is reduced while the pressure caught in the filtered water line 6 is lowered. As described above, the contact point of the pressure switch 100 is connected as described above to supply power to the water supply valve 1 and the pump 4 to supply water as in the initial stage and to store the filtered water in the pressure storage tank 8. Will be.
그러나 역삼투막 정수기는 수도콕을 잠근 상태나 또는 단수시에 수도콕으로부터 수도물이 유입이 안될 경우에도 동작이 되므로 압력저장 탱크전단에 연결된 압력스위치의 접점이 계속해서 연결되어져 있는 상태가 되므로 계속 급수배브와 펌프가 가동되므로 전력이 낭비되고 펌프가 공운전하게 되어 손상의 원인이 되는 문제점이 발생되었다.However, since the reverse osmosis membrane water purifier operates even when the tap water is locked or when tap water does not flow from the tap water at the time of water cutting, the contact point of the pressure switch connected to the pressure storage tank front is continuously connected. Since the pump is running, power is wasted and the pump is idle, causing problems.
본 발명은 이러한 점을 감안하여 발생한 것으로서 급수밸브에 의하여 급수된 수도물이 전처리필터 및 후처리필터를 거쳐 펌프에 의하여 역삼투막을 거치면서 여과됨과 더불어 발생된 농축수가 배출되는 농축수라인과, 상기 농축수라인으로 유출되는 농축수에 의하여 급수여부를 감지하는 급수감지부와 상기 급수감지 여부에 따라 급수밸브 및 펌프의 작동을 제어하는 제어부로 구성한 것으로서 단수시나 수도콕이 개방되지 않은 상태에 급수밸브와 펌프가 공운정을 하는 것을 방지토록하는데 목적이 있다.The present invention has been made in view of this point, and the tap water supplied by the water supply valve is filtered while passing through the reverse osmosis membrane by a pump through a pretreatment filter and a post treatment filter, and a concentrated water line through which the generated concentrated water is discharged. It consists of a water supply detecting part that detects water supply by the concentrated water flowing out into the line and a control unit that controls the operation of the water supply valve and the pump according to the water supply detection. The purpose is to prevent the government from operating air traffic.
본 발명 정수기를 제 2 도 및 제 3 도에 의하여 설명한다.The water purifier of the present invention will be described with reference to FIGS. 2 and 3.

그리고, 급수감지부는 농축수가 유입되는 유입구(111)가 형성된 농축수통(112)과 상기 농축수통(112)에 유입된 농축수의 잔존여부를 감지하는 감지부와 상기 농축수통(112)에 유입된 농축수가 유출되는 유출구(113)와 상기 농축수통(112)에 잔존하는 농축수가 유출될때 농축수통(112)내로 공기를 유입시키는 공기유입부와 상기 감지부의 작동에 따라 급수배브(101)와 펌프(104)의 작동을 제어하는 제어부(120)로 구성하였다.In addition, the water supply detection unit is introduced to the concentrated water container 112 and the concentrated water container 112 is formed in the inlet 111 through which the concentrated water flows in and the residual water flowing into the concentrated water container 112. The water inlet port 101 and the pump according to the operation of the air inlet and the sensing unit for introducing air into the brine 112 when the brine is discharged from the outlet 113 and the brine remaining in the brine 112 is discharged ( The control unit 120 for controlling the operation of the 104.
그리고, 상기 감지부는 농축수통(112)에 유입된 농축수에 의하여 통전이 되는 센서(114)와 상기 센서(114)가 농축수통(112)에 절연 및 농축수가 누수되지 않도록 하는 패킹(115)에 의하여 결합되었다.In addition, the sensing unit may be insulated by the concentrated water introduced into the brewer 112 and the packing 115 to insulate the sensor 114 from the insulator and the leaked condensed water. Combined.
그리고 공기유입부는 농축수통(112)내로 공기가 유입되는 구멍(116)과 상기 농축수통(112)에 고이는 농축수가 구멍(116)을 통하여 유출되는 것을 방지토록한 플로트(117)와 상기 플로트(117)가 삽입되어 상하작동할 수 있는 삽입홈(118)으로 구성하였다.In addition, the air inlet portion floats 117 and the float 117 to prevent the air from flowing through the holes 116 and the concentrated water accumulated in the concentrated water container 112 through the hole 116. ) Was inserted into the insertion groove 118 that can be operated up and down.
그리고 상기 제어부는 센서(114)에 의하여 감지된 신호가 신스템 제어부(120)의 제어신호에 의하여 스위칭되어 부하에 동작전원을 공급하는 부하구동부(121)와 상기 동작을 표시하는 표시램프를 구성하였다.In addition, the control unit configured a load driving unit 121 for supplying operating power to the load by switching the signal sensed by the sensor 114 by the control signal of the synth control unit 120 and a display lamp for displaying the operation. .
이와 같은 본 발명의 작용효과를 제 2 도 및 제 3 도에 의하여 설명하면 다음과 같다.The operational effects of the present invention will be described with reference to FIGS. 2 and 3 as follows.
정수된 물을 먹기 위하여 취출콕(109)을 개방시켜 정수를 사용하면 여과수라인(106)내 걸려 있는 압력이 낮아지면서 압력스위치(110)에 설정된 동작압력 이하로 되면 압력스위치(110)의 접점이 연결되고 이를 제어부(120)에서 감지하여 ON일 경우에는 급속밸브(101)와 펌프(104)에 전원을 인가하여 수도물을 급수할 수 있도록 한다.When using the purified water to open the blower cock 109 in order to eat the purified water, the pressure in the filtered water line 106 is lowered and the contact point of the pressure switch 110 is lower than the operating pressure set in the pressure switch 110 When it is connected and sensed by the control unit 120, the power is supplied to the quick valve 101 and the pump 104 to supply the tap water.
이때 수도물이 단수되었거나 수도콕이 잠겼을 경우에는 상기와 같이 급수밸브(101)와 펌프(104)에 전원이 인가된 상태에서 수도물이 급수되지 아니함과, 더불어 제어부(120)에서 시간을 적산하기 시작하여 설정된 시간동안에 수도콕에 연결된 급수호스(101')와 급수밸브(101)와 전처리필터(102)와 후처리필터(103)와 펌프(104)와 역삼투막(105)에 급수가 되지 아니하기 때문에 농축수라인(107)으로 농축수가 유출되지 않는다.At this time, when the tap water is single or the cock cock is locked, the tap water is not supplied while the power supply is applied to the water supply valve 101 and the pump 104 as described above, and the controller 120 starts to accumulate time. Since water is not supplied to the water supply hose 101 ′, the water supply valve 101, the pretreatment filter 102, the aftertreatment filter 103, the pump 104, and the reverse osmosis membrane 105 connected to the tap cock during the set time. The concentrated water does not flow into the water line 107.
이때 농축수통(112)내에 농축수가 고이지 아니하기 때문에 센서(114)간에 농축수에 의한 통전이 이루어지지 아니한다.At this time, since the concentrated water does not accumulate in the concentrated water container 112, energization by the concentrated water is not performed between the sensors 114.
따라서 상기 설정된 시간이 지나면 제어부(120)가 이를 인지할 수 있도록 표시램프를 점등하고 공운전하고 있는 급수밸브(101)와 펌프(104)의 인가전원을 차단하여 운전을 멈추게 하는 것이다.Therefore, after the set time has elapsed, the control unit 120 turns on the display lamp to stop the operation by cutting off the power supply of the water supply valve 101 and the pump 104 which are in the air operation.
또한 수도물이 정상적으로 통수되고 수도콕이 열려진 상태에서는 수도물이 급수호스(101')와 급수밸브(101)와 전처리필터(102)와 후처리필터(103)와 펌프(104)와 역삼투막(105)을 거쳐 여과된 여과수는 여과수라인(106)을 거쳐 압력저장탱크(108)에 모아지거나 취출콕(109)을 통하여 취출된다.In addition, when the tap water is normally passed through and the cock is opened, the tap water is connected to the water supply hose 101 ', the water supply valve 101, the pretreatment filter 102, the aftertreatment filter 103, the pump 104, and the reverse osmosis membrane 105. Filtrate filtered through is collected in the pressure storage tank 108 via the filtrate line 106 or withdrawn through the blowout cock (109).
이와 같이 여과가 이루어지면서 역삼투막(105)에서 걸러진 농축수가 농축수라인(107)를 따라 유입구(111)를 통해 농축수통(112)내에 유입된다.As the filtration is performed as described above, the concentrated water filtered from the reverse osmosis membrane 105 is introduced into the concentrated water container 112 through the inlet 111 along the concentrated water line 107.
이때 농축수통(112)에 유입된 농축수가 유출되는 유출구(113)의 내경이 유입구(111)의 내경보다 작게 형성되어져 있기 때문에 유입구(111)를 통하여 유입된 농축수가 농축수통(112)내에 모이게 된다.At this time, since the inner diameter of the outlet 113 through which the concentrated water introduced into the brine 112 flows out is formed smaller than the inner diameter of the inlet 111, the concentrated water introduced through the inlet 111 is collected in the brine 112. .
따라서 농축수통(112)에 고이면서 수위가 센서(115)보다 높아지면 농축수에 의하여 센서(115)가 통전된다.Therefore, when the water level is higher than the sensor 115 while accumulating in the concentrated water container 112, the sensor 115 is energized by the concentrated water.
따라서 센서(115)가 통전되었음을 감지한 제어부(120)는 급수밸브(101)와 펌프(104)가 계속적으로 운전을 수행하도록 한다.Therefore, the controller 120 that detects that the sensor 115 is energized allows the water supply valve 101 and the pump 104 to continuously operate.
그리고 농축수통(112)내로 유입되는 농축수의 수위가 계속 높아지게 되면 수위에 따라 플로트(117)가 삽입홈(118)내에서 상승되어 농축수통(112)내에 가득차게 되는 농축수가 누수되는 아니하도록 구멍(116)을 막아준다.If the level of the concentrated water flowing into the brine 112 continues to increase, the float 117 is raised in the insertion groove 118 according to the water level so that the concentrated water filled in the brine 112 does not leak. Block (116).
이와 같이 여과가 계속됨에 따라 정수가 여과수라인(106)을 통해 압력저항탱크(108)에 저장됨과 더불어 여과수라인(106)상에 압력이 상승된다.As the filtration continues, the purified water is stored in the pressure resistance tank 108 through the filtrate line 106, and the pressure is increased on the filtrate line 106.
이때 압력이 압력스위치(110)에 설정된 압력이상이 되면 압력스위치(110)가 OFF되고 이를 제어부(120)가 인식하여 급수밸브(101)와 펌프(104)의 운전을 차단시켜 수도물이 여과되는 것을 중지시킨다.At this time, when the pressure is higher than the pressure set in the pressure switch 110, the pressure switch 110 is turned off and the control unit 120 recognizes this to block the operation of the water supply valve 101 and the pump 104 to filter the tap water. Stop it.
그러나, 수도물의 여과가 이루어지지 아니한다 하더라도 농축수통(112)내에 농축수가 고여져 있어 유출구(113)를 통하여 농축수가 유출되는데 이때, 농축수가 유출됨과 더불어 수위가 낮아지므로 인하여 플로트(117)가 하강한다.However, even though filtration of tap water is not made, the concentrated water is accumulated in the concentrate water tank 112, and the concentrated water is discharged through the outlet 113. At this time, the float 117 is lowered because the concentrated water is discharged and the water level is lowered. .
따라서 플로트(117)가 막고있던 구멍(116)이 열리면서 농축수통(112)내로 공기가 유입되기 때문에 유출구(113)로 농축수가 유출되는 것이 원활하게 이루어진다.Therefore, since the air is introduced into the thickening container 112 while the hole 116 blocked by the float 117 is opened, the concentrated water is smoothly discharged to the outlet 113.
따라서 농축수통(112)내에 잔류해 있던 농축수가 유출구가(113)를 통해 완전히 배수되어 센서(114)가 농축수에 의하여 통전되는 것을 방지하여 초기상태가 되도록 한다.Therefore, the concentrated water remaining in the brine 112 is completely drained through the outlet 113 to prevent the sensor 114 from being energized by the brine so as to be in an initial state.
이와 같은 본 발명은 수도물이 단수되거나 수도콕이 잠겨 수도물이 공급되지 아니할때는 급수밸브와 펌프가 공운전되는 것을 방지하여 줌으로써 공운전이 의한 전력낭비를 막을 수 있다.The present invention as described above can prevent power supply by idle operation by preventing the water supply valve and the pump from being idle when the tap water is singular or the cock is locked and the tap water is not supplied.
그리고, 급수의 여부 또는 수도콕을 잠가놓았음을 표시램프로 알려주기 때문에 사용자의 실수를 방지할 수 있는 발명이다.And, it is an invention that can prevent the user's mistake because it informs the indicator lamp that the water supply or the cock cock is locked.
