Specifically, when a predetermined time elapses from a temperature to be controlled, the power is turned off and when the temperature rises again, the cooler is turned on to reduce the supercooling and power consumption of the cooler. The present invention relates to a compensation control method of a thermoelectric element cooler.

종래의 열전소자를 이용한 냉각기는, 물을 담는 수조(1)와, 수조의 상부에 취부되어 수종의 물을 냉각시키는 열전소자(2)와, 열전소자(2)의 발열부분에서 발생되는 열을 배출하는 팬(3)과, 수조(1)의 하단에 취부되어 수조에 담겨있는 물의 온도를 감지하는 온도감지부(4)를 구비한다.A conventional cooler using a thermoelectric element includes a water tank 1 containing water, a thermoelectric element 2 mounted on an upper portion of the water tank to cool several kinds of water, and heat generated in a heat generating portion of the thermoelectric element 2. It is provided with a fan (3) for discharging, and a temperature sensing unit (4) attached to the lower end of the water tank (1) for sensing the temperature of the water contained in the water tank.

종래의 열전소자냉각기의 제어흐름을 살펴보면 다음과 같다.The control flow of the conventional thermoelectric element cooler is as follows.

먼저 냉각기는 온도를 감지한다(S1). 이때 수조(1)의 하단에 설치되어 있는 온도감지부(4)를 통하여 수조(1)에 담겨있는 물의 온도를 감지한다.First the cooler senses the temperature (S1). At this time, the temperature of the water contained in the water tank 1 is sensed through the temperature sensing unit 4 installed at the bottom of the water tank 1.

온도감지부(4)를 통하여 수조(1)에 담겨있는 물의 온도감지가 끝나면, 온도감지부(4)를 통하여 감지된 온도가 설정된 온도보다 높은지를 판단한다(S2). 이때 설정된 온도는 5℃인데, 이것은 열전소자(2)가 4℃이하로 냉각을 시키는 데에는 어려움이 따르기 때문에 5℃로 설정한 것이다.After the temperature detection of the water contained in the water tank 1 through the temperature detection unit 4, it is determined whether the temperature detected by the temperature detection unit 4 is higher than the set temperature (S2). At this time, the set temperature is 5 ° C, which is set to 5 ° C because it is difficult to cool the thermoelectric element 2 below 4 ° C.

만약 판단(S2)에서 온도감지부(4)를 통하여 감지된 온도가 미리 설정되어 있는 온도보다 높지 않다고 판단되면, 즉 온도감지부(4)를 통하여 감지된 온도가 미리 설정된 온도와 같은 온도이거나 더 낮은 온도일 경우에는 열전소자(2)에 온(on)시키지 않고 초기상태로 되돌아간다.If it is determined in the determination S2 that the temperature sensed by the temperature detector 4 is not higher than the preset temperature, that is, the temperature detected by the temperature detector 4 is equal to or more than the preset temperature. When the temperature is low, the thermoelectric element 2 is returned to its initial state without being turned on.

하지만 판단(S2)에서 온도감지부(4)를 통하여 감지된 수조(1)의 물의 온도가 미리 설정되어 있는 온도보다 높다고 판단되면, 즉, 온도감지부(4)를 통하여 감지된 온도가 5℃보다 높다고 판단되면 냉각기는 열전소자(2)에 전원을 인가하여 온(on)시킨다(S3).However, if it is determined in the determination S2 that the temperature of the water of the water tank 1 detected through the temperature sensing unit 4 is higher than the preset temperature, that is, the temperature detected by the temperature sensing unit 4 is 5 ° C. If it is determined to be higher than the cooler by applying power to the thermoelectric element (2) (S3).

그런 다음 다시 온도감지부(4)를 통하여 수조(1)에 담겨있는 물의 온도를 감지한다(S4).Then, the temperature of the water contained in the water tank 1 through the temperature sensing unit 4 again detects (S4).

온도감지부(4)를 통하여 수조(1)에 담겨있는 물의 온도감지가 끝나면, 온도감지부(4)를 통하여 감지된 온도가 미리 설정된 온도보다 같거나 낮은지를 판단한다(S5).After the temperature sensing of the water contained in the water tank 1 through the temperature sensing unit 4, it is determined whether the temperature detected by the temperature sensing unit 4 is equal to or lower than the preset temperature (S5).

판단(S5)에서 온도감지부(4)를 통하여 감지한 수조(1)의 물의 온도가 미리 설정된 온도보다 높다면, 즉 온도감지부(4)를 통하여 감지한 온도가 5℃보다 높다면 열전소자(2)는 계속적으로 온(on)상태로 유지한다.If the temperature of the water of the water tank 1 detected through the temperature sensor 4 in the determination (S5) is higher than the preset temperature, that is, the temperature detected by the temperature sensor 4 is higher than 5 ℃ thermoelectric element (2) remains on continuously.

하지만 판단(S5)에서 온도감지부(4)를 통하여 감지된 온도가 미리 설정된 온도, 즉 5℃와 같거나 더 낮다면 냉각기는 열전소자(2)의 전원을 차단하여 냉각을 중지시킨다(S6).However, if the temperature sensed by the temperature sensing unit 4 in the determination (S5) is less than or equal to a predetermined temperature, that is, 5 ° C, the cooler cuts off the power of the thermoelectric element (2) to stop cooling (S6). .

도 3을 참조하면 수조(1)의 물의 온도가 6℃까지는 냉각이 잘 이루어지나, 수조(1)의 물의 온도를 5℃이하로 냉각하는데에는 시간이 많이 소요됨을 알 수 있다.Referring to FIG. 3, although the cooling of the water of the water tank 1 is performed well up to 6 ° C., it can be seen that it takes a long time to cool the water of the water tank 1 to 5 ° C. or less.

그리하여 열전소자(2)가 수조(1)의 물을 설정된 온도로 냉각시키기 위하여 오랜 시간동안 구동되어서 소비전력이 커지는 문제점이 있었다.Thus, the thermoelectric element 2 is driven for a long time to cool the water in the water tank 1 to a set temperature, there is a problem that the power consumption increases.

본 발명은 상기한 문제를 해결하기 위하여 안출된 것으로 그 목적은, 제어하고자 하는 온도에서 소정시간이상 경과하게 되면 전원을 오프하고 다시온도가 상승하면 냉각기를 온시켜서 냉각기의 과냉 및 소비전력을 감소시킬 수 있는 열전소자냉각기의 보상제어방법을 제공하고자 하는 것이다.The present invention has been made to solve the above problems, the object of which is to turn off the power when a predetermined time or more at the temperature to be controlled and to turn on the cooler when the temperature rises again to reduce the supercooling and power consumption of the cooler. It is to provide a compensation control method of a thermoelectric element cooler.

본 발명에 따른 열전소자 냉각기는 물을 담는 수조의 상부에는 수조의 물을 냉각시키는 열전소자(42)가 설치되며, 또한 열전소자(42)를 구동시키는 열전소자구동부(41)가 제어부(30)에 전기적으로 접속되어 있다.In the thermoelectric element cooler according to the present invention, a thermoelectric element 42 for cooling the water in the tank is installed on the upper portion of the water tank, and the thermoelectric element driving part 41 for driving the thermoelectric element 42 is the controller 30. Is electrically connected to.

그리고 열전소자(42)의 상단에는 발열부분에서 발생되는 열을 배출하는 팬을 호전시키는 팬모터(52)가 설치되어 있는데, 이 팬모터(52)는 팬모터구동부(51)에 접속되어 있다.At the upper end of the thermoelectric element 42, a fan motor 52 for improving a fan for discharging heat generated from the heat generating portion is provided. The fan motor 52 is connected to the fan motor driving unit 51.

또 팬모터구동부(51)는 제어부(30)에 접속되어 있다.In addition, the fan motor drive unit 51 is connected to the control unit 30.

한편 수조의 하단에는 수조에 담겨있는 물의 온도를 감지하는 온도감지부(10)가 설치되어 있는데 이 온도감지부(10)는 제어부(30)에 접속되어 있다.On the other hand, the bottom of the tank is provided with a temperature sensing unit 10 for sensing the temperature of the water contained in the tank, the temperature sensing unit 10 is connected to the control unit 30.

또한 시간을 적산하는 타이머(20)가 제어부(30)에 접속되어 있다.In addition, a timer 20 that integrates time is connected to the control unit 30.

본 발명에 따른 열전소자냉각기 보상제어방법을 제어 흐름도에 따라서 살펴보겠다.The thermoelectric element cooler compensation control method according to the present invention will be described according to a control flowchart.

먼저 제어부(30)는 수조에 담겨있는 물의 온도를 감지한다(S10). 이때 수조의 하단에 설치되어 있는 온도감지부(10)를 통하여 수조에 담겨있는 물의 온도를 감지한다.First, the control unit 30 senses the temperature of the water contained in the tank (S10). At this time, the temperature of the water contained in the tank is sensed through the temperature sensing unit 10 installed at the bottom of the tank.

온도감지부(10)를 통하여 수조에 담겨있는 물의 온도감지가 끝나면, 제어부(30)는 온도감지부(10)를 통하여 감지된 온도가 제1임계온도보다 높은지를 판단한다(S20). 이때 제1임계온도는 5℃인데, 이것은 열전소자(2)가 4℃이하로 냉각을 시키는 데에는 어려움이 따르기 때문에 5℃로 설정한 것이다.After the temperature detection of the water contained in the water tank through the temperature sensing unit 10, the control unit 30 determines whether the temperature detected by the temperature sensing unit 10 is higher than the first critical temperature (S20). At this time, the first critical temperature is 5 ° C, which is set to 5 ° C because it is difficult to cool the thermoelectric element 2 to 4 ° C or less.

만약 판단(S20)에서 온도감지부(10)를 통하여 감지된 온도가 제1임계온도보다 높지 않다고 판단되면, 즉 온도감지부(10)를 통하여 감지된 온도가 제1임계온도와 같은 온도이거나 더 낮은 온도일 경우에는 제어부(30)는 열전소자(42)를 온(on)시키지 않고 초기상태로 되돌아간다.If it is determined in the determination (S20) that the temperature sensed by the temperature sensing unit 10 is not higher than the first threshold temperature, that is, the temperature sensed by the temperature sensing unit 10 is the same temperature or more than the first critical temperature. When the temperature is low, the controller 30 returns to the initial state without turning on the thermoelectric element 42.

하지만 판단(S20)에서 온도감지부(10)를 통하여 감지된 수조의 물의 온도가 제1임계온도보다 높다고 판단되면, 즉, 온도감지부(10)를 통하여 감지된 온도가 5℃보다 높다고 판단되면 제어부(30)는 열전소자구동부(41)를 구동시켜 열전소자(42)에 전원을 인가하여 온(on)시킨다(S30).However, if it is determined in the determination (S20) that the temperature of the water of the tank detected through the temperature sensing unit 10 is higher than the first threshold temperature, that is, if the temperature detected by the temperature sensing unit 10 is higher than 5 ° C. The controller 30 drives the thermoelectric element driver 41 to apply power to the thermoelectric element 42 to turn it on (S30).

그런 다음 제어부(30)는 다시 온도감지부(10)를 통하여 수조에 담겨있는 물의 온도를 감지한다(S40).Then, the control unit 30 again detects the temperature of the water contained in the water tank through the temperature sensing unit 10 (S40).

온도감지부(10)를 통하여 수조에 담겨있는 물의 온도감지가 끝나면, 제어부(30)는 온도감지부(10)를 통하여 감지된 온도가 제1임계온도보다 같거나 낮은지를 판단한다(S50).After the temperature detection of the water contained in the water tank through the temperature sensing unit 10, the controller 30 determines whether the temperature detected by the temperature sensing unit 10 is equal to or lower than the first critical temperature (S50).

판단(S50)에서 온도감지부(10)를 통하여 감지한 수조의 물의 온도가 제1임계온도보다 높다면, 제어부(30)는 온도감지부(10)를 통하여 감지된 온도가 제1임계온도보다 높고 제2임계온도보다 낮거나 같은지를 판단한다(S51). 이때 제2임계온도는 6℃이다.If the temperature of the water of the tank detected by the temperature sensing unit 10 in the determination (S50) is higher than the first critical temperature, the control unit 30 is a temperature detected by the temperature sensing unit 10 than the first critical temperature. It is determined whether it is high and lower than or equal to the second threshold temperature (S51). At this time, the second critical temperature is 6 ℃.

판단(S51)에서 온도감지부(10)를 통하여 감지된 온도가 제2임계온도보다 높다고 판단되면 제어부(30)는 계속적으로 열전소자구동부(41)를 구동시키고 그에 따라서 열전소자(42)는 계속적으로 온(on)상태로 유지한다(S30).If it is determined in S51 that the temperature sensed by the temperature sensing unit 10 is higher than the second threshold temperature, the controller 30 continuously drives the thermoelectric element driving unit 41 and accordingly the thermoelectric element 42 continuously Keep on (on) as (S30).

하지만 판단(S51)에서 온도감지부(10)를 통하여 감지한 온도가 제1임계온도보다 높고 제2임계온도보다 낮거나 같다고 판단되면 제어부(30)는 타이머(20)를 작동시킨다(S52). 타이머(20)는 제어부(30)의 제어에 따라서 작동되어 시간을 적산한다.However, if it is determined in S51 that the temperature sensed by the temperature sensing unit 10 is higher than the first threshold temperature and lower than or equal to the second threshold temperature, the controller 30 operates the timer 20 (S52). The timer 20 operates under the control of the controller 30 to accumulate time.

그런 다음 제어부(30)는 타이머(20)에 적산된 시간이 소정시간, 약 15분을 경과하였는지를 판단한다(S53).Then, the controller 30 determines whether the time accumulated in the timer 20 has passed a predetermined time, about 15 minutes (S53).

판단(S53)에서 타이머(20)의 적산시간이 15분을 경과하지 않았다고 판단되면 제어부(30)는 계속적으로 열전소자구동부(41)를 구동시키고 그에 따라서 열전소자(42)는 계속적으로 온(on)상태로 유지한다.If it is determined in operation S53 that the integration time of the timer 20 has not elapsed 15 minutes, the controller 30 continuously drives the thermoelectric element driving unit 41 and accordingly the thermoelectric element 42 is continuously turned on. Keep it in the

하지만 판단(S53)에서 타이머(20)의 적산시간(도 6의 t1에서 t2구간)이 15분을 경과하였다고 판단되면 제어부(30)는 열전소자구동부(41)의 작동을 중지시켜 열전소자(42)의 전원을 차단하고 냉각을 중지시킨다(S60).However, if it is determined in step S53 that the integration time of the timer 20 (section t1 to t2 in FIG. 6) has elapsed for 15 minutes, the controller 30 stops the operation of the thermoelectric element driver 41 to thermoelectric element 42. ) To turn off the power and stop the cooling (S60).

이상에서 상세하게 설명한 바와 같이 본 발명에 따른 열전소자냉각기 보상제어방법에 의하여, 열전소자를 구동시켜 수조의 냉각이 실시되었을 때 수조 내용물의 온도가 제1임계온도와 그 보다 더 높은 온도인 제2임계온도사이의 온도에서 소정시간동안 유지되거나 제1임계온도이하의 온도가 될 때 열전소자를 오프시킴으로서 소비전력을 줄이고 장시간 운전에 의한 열전소자냉각기의 과냉을 방지할 수 있다.As described in detail above, according to the thermoelectric element cooler compensation control method according to the present invention, when the thermoelectric element is driven to cool the tank, the temperature of the tank contents is the first critical temperature and the second higher temperature. By turning off the thermoelectric element when it is maintained for a predetermined time at a temperature between the critical temperatures or below the first critical temperature, it is possible to reduce power consumption and to prevent overcooling of the thermoelectric element cooler due to long operation.
