본 고안은 주로 음료수나 식품 자동판매기 또는 식수공급기등에 내장하는 냉수공급장치의 냉가 온도조절장치에 관한 것이다.The present invention mainly relates to a cold temperature control device of a cold water supply device embedded in a beverage or food vending machine or a drinking water supply.
냉수공급장치는 내장된 물은 0도 전후의 빙결()직전의 얼음물 상태로 보존 또는 공급하는 장치를 말하는바 본 고안은 냉각기가 장설된 상자속에 물을넣고 냉각기 바로 옆에 3개 1조로된 전극봉을 넣어서 물의 액체상태와 고체상태사이의 임피던스 값이 서로 다른 것을 이용하여 전극봉 간격으로 얼음 두께를 조절하므로서 상자속의 물을 빙점까지 차갑게 유지할수 있고 냉수의 토출이 용이하게 한데 그 특징이 있는 것이다.The cold water supply unit has a built-in water around 0 degrees This device is designed to store or supply in the state of ice water immediately before. The present invention puts water into a box installed with a cooler and puts three sets of electrodes next to the cooler so that the impedance values between the liquid and solid states of the water are different. By adjusting the thickness of the electrodes at different electrode intervals, the water in the box can be kept cool to the freezing point, and the cold water can be easily discharged.
종래의 얼음물 공급장치는 온도 검출을 써미스트등 온도 검출용 센서를 사용하여 냉동용 콤프레셔를 구동시켜서 냉각 조절을하는 방식으로 되어있어서 조정점이 빙점이하로 되어 장시간 방치하면 얼음덩어리가 생겨서 유출구를 막는다든지 너무 냉각되면 물전체가 얼음이 되어 냉수가 공급되지 않는 결점이 따르고 반대로 빙점이상으로 조정되면 물이 차지않게되어 결국 빙점 조정이 정확하게 이루어지지 않는 문제점이 있었다.Conventional ice water supply device uses the temperature detection sensor such as thermistor to drive the refrigeration compressor to control the cooling, so if the control point is below the freezing point and left for a long time, an ice block is formed to block the outlet. If the cooling is too cold, the whole water becomes ice, the cold water is not supplied, the contrary, if the freezing point is adjusted above the water does not occupy, there was a problem that the freezing point adjustment is not made correctly.
본 고안은 이를 시정보완하여 매우 간단한 구조의 전극봉 내장장치에 의하여 물을 빙점까지 정확한 온도로 냉각 할수있게하여 냉수공급 분야에 널리 활용할수 있도록 한 것으로 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is designed to be able to cool the water to the exact temperature to the freezing point by the electrode built-in device of a very simple structure to be widely used in the field of cold water supply, which will be described in detail based on the accompanying drawings as follows.
본 고안은 냉수조(2)의 일측에 냉각기(1)가 설치되고 이 냉각기(1)의 인접부에 3개 1조로된 전극봉(S1)(S2)(S3)을 상기 냉각기(1)의 가동회로와 연결하는 구성으로 된다.According to the present invention, a cooler 1 is installed at one side of the cold water tank 2, and the electrode rods S 1 (S 2 ) (S 3 ), which are three in one adjacent part of the cooler 1, are connected to the cooler 1 Is connected to the movable circuit.
냉각기(1)의 콤프레셔를 구동하는 회로는 제3, 2도와 같다.The circuit which drives the compressor of the cooler 1 is the same as that of 3rd, 2nd degree.
이회로의 구성에 의하여 설명하면 T1에서 나온 Ac전압이 저항(R1)과 제너다이오드(D1)(D2)를 통하여 A점에 일정하게 전류를 공급한다.According to the configuration of this circuit, the Ac voltage from T 1 supplies a constant current to point A through the resistor R 1 and the zener diode D 1 (D 2 ).
냉수조(2)의 속의 물이 전부 액체 상태인 경우는 전극봉(S1)과 전극봉(S3)사이에는 물의 상태로 인해 임피던스가 낮아져 B점의 전압은 낮게된다.When all the water in the cold water tank 2 is in a liquid state, the impedance is lowered due to the state of water between the electrode rod S 1 and the electrode rod S 3 , so that the voltage at the point B is lowered.
B점의 전압이 저항(R4), (R5)으로 분배되어 전압이 C점 보다 낮아서 OP1의 출력이 LOW상태로 되면 콘덴스(C4)에 충전되어 있던 전압은 방전회로(R7)(R6)(D4)로 방전되어 D점의 전압이 E점 보다도 낮아지고 따라서 OP2의 출력이 High로 되어 트랜지스터(TR1)가 ON되어 릴레이(Ry1)가 ON된다.When the voltage at point B is divided into resistors (R 4 ) and (R 5 ) and the voltage is lower than point C and the output of OP 1 goes low, the voltage charged in the condense (C 4 ) is discharge circuit (R 7). (R 6 ) (D 4 ), the voltage at the point D becomes lower than the point E. Therefore, the output of the OP 2 becomes high, the transistor TR 1 is turned on, and the relay Ry 1 is turned on.
이 릴레이(Ry1)의 접점으로 냉각 콤프레셔(Comp1)가 ON되어 냉각을 시작하며 한쪽 접점으로 전극봉 2개(S2)(S3)는 연결된다.The cooling compressor Comp 1 is turned on at the contact point of the relay Ry 1 to start cooling, and two electrodes S 2 and S 3 are connected to one contact point.
계속 냉각 콤프레셔(Comp1)가 가동하여 얼음이 검출봉(S2)까지 얼면 검출봉(S2)에는 제2도 (b)와 같이 얼음이 덮히어 전극봉(S2)사이의 임피던스가 높아진다.Continue cooling and compressor (Comp 1) the movable high impedances between the ice detection rod (S 2) to the frozen, the detection rod (S 2) has a second degree control of ice is covered as shown in (b) electrodes (S 2).
따라서 B점 전압은 상승하며 전술한 기능과는 반대의 회로가 성립하여 냉각 콤프레셔(Comp1)는 Off된다.Therefore, the point B voltage rises and a circuit opposite to the above function is established, and the cooling compressor Comp 1 is turned off.
또한 전극봉(S2)과 검출봉(S3)사이의 접점도 Off되어 다시 전극봉(S1)과 (S3)사이의 임피던스를 검출하게 된다.In addition, the contact between the electrode (S 2 ) and the detection rod (S 3 ) is also off to detect the impedance between the electrode (S 1 ) and (S 3 ) again.
얼음이 검출봉(S3)까지 녹으면 제2도 (c)와 같이 전극봉(S1)과 (S3)사이의 임피던스가 낮아져 처음의 상태와 동일한 조건으로 콤프레셔(Comp1)가 ON된다.When the ice melts to the detection rod S 3 , as shown in FIG. 2C, the impedance between the electrode rods S 1 and S 3 is lowered, and the compressor Comp 1 is turned on under the same condition as in the initial state.
이와같은 동작이 반복되면 얼음은 냉각기(1)에서 전극봉(S1)과 (S3)사이까지만 얼고 나머지는 냉수상태로 계속유지되고 이 상태에서 교반모우터(3)로 팬(3')을 계속돌려서 얼음에 부딪치게 하여 물의 온도를 빙점으로 유지시키는 것이다.If this operation is repeated, the ice freezes only between the electrodes (S 1 ) and (S 3 ) in the cooler (1) and the remainder is kept in the cold water state, and in this state the fan (3 ') with the stirring motor (3) Keep turning and hitting the ice to keep the water temperature at freezing point.
이상과 같이 본 고안의 구조에 의하면 냉수조에 설치한 3개 1조로된 전극봉의 설치에 의하여 전극봉사이에만 제한적으로 얼음을 얼리고 이 얼음에 교반팬(3')으로서 계속물을 접촉순환시켜 항상 빙점에 거의 일치하는 냉수를 보존 및 공급할수가 있으므로 작동이 정확하고 냉수 공급장치의 구조가 간단하게 되며 또한 공급장치전반이 고장의 우려가 없어서 각종 냉수공급 시스템에 널리 실용적으로 적용할수가 있는 잇점이 있다.As described above, according to the structure of the present invention, the ice is limited only between the electrode rods by the installation of three sets of electrode rods installed in the cold water tank, and the water is continuously circulated as a stirring fan (3 ') by contacting the ice. Since almost identical cold water can be stored and supplied, the operation is accurate and the structure of the cold water supply device is simple, and there is no possibility of failure of the entire supply device, and thus it is widely applicable to various cold water supply systems.
