일반적으로 전기레인지는 화구에, 고주파 동작전력이 인가됨에 따라 자기장을 발생하는 인덕션 코일을 구비하고 있다. 상기 인덕션 코일의 상부에는 조리용구를 안치(安置)하는 상판이 구비되어 있다.Generally, an electric range is provided with an induction coil which generates a magnetic field as a high-frequency operating power is applied to the hearth. An upper plate for placing a cooking utensil is provided on an upper portion of the induction coil.
상기 상판은, 상기 조리용구에 의하여 상기 인덕션 코일이 손상되지 않도록 보호하고, 또한 열 및 외부의 충격등에 의하여 쉽게 손상되지 않도록 하기 위하여 세라믹 유리 등과 같은 강화유리를 사용하고 있다.The upper plate protects the induction coil from being damaged by the cooking utensil and uses a tempered glass such as ceramic glass to prevent the induction coil from being easily damaged by heat or external impact.
상기 상판의 상부에 안치하는 조리용구의 바닥면에는 상기 자기장에 대한 저항 성분(철 성분)을 포함하고 있다.The bottom surface of the cooking utensil positioned above the upper plate includes a resistance component (iron component) for the magnetic field.
이러한 전기레인지는 상기 화구가 위치된 상판의 상부에 조리용구를 안치시킨 상태에서 상기 인덕션 코일에 고주파 동작전력이 인가될 경우에 상기 인덕션 코일에서 자기장이 발생하게 되고, 상기 자기장은 상기 상판의 상부에 안치된 조리용구의 바닥면을 통과하게 된다.When a high-frequency operating power is applied to the induction coil in a state where a cooking utensil is placed on an upper part of the top plate on which the cooking pot is located, a magnetic field is generated in the induction coil, And passes through the bottom surface of the placed cooking utensil.
상기 조리용구는 바닥면에 포함되어 있는 자기장에 대한 저항 성분은 상기 자기장에 따른 와류현상이 발생하게 되고, 상기 와류현상에 따른 유도가열로 상기 조리용구의 바닥면은 약 500∼600℃로 가열되어 소정의 음식물을 조리할 수 있다.The resistance component to the magnetic field included in the bottom surface of the cooking utensil causes a vortex phenomenon according to the magnetic field and the bottom surface of the utensil is heated to about 500 to 600 캜 by induction heating according to the vortex phenomenon A predetermined food can be cooked.
여기서, 상기 상판에는 자기장에 따른 저항 성분이 거의 없으므로 상기 자기장에 따른 와류현상이 발생되지 않아 가열되지는 않는다.Here, since there is almost no resistance component in accordance with the magnetic field, the upper plate does not generate a vortex according to the magnetic field and is not heated.
그러나 상기 상판에는 상기 조리용구의 바닥면이 접촉되어 있으므로 상기 바닥면의 열이 상기 상판으로 전달된다.However, since the bottom surface of the cooking utensil is in contact with the top plate, heat of the bottom surface is transmitted to the top plate.
그러므로 상기 전기레인지의 전원을 오프시켜 동작을 정지시켜도 상기 상판에는 상당한 시간동안 잔열이 남아있게 되는 것으로서 사용자가 상기 상판에 접촉할 경우에 상기 상판의 접촉 부위에 화상을 입게 되는 등의 안전사고가 발생할 수 있다.Therefore, even if the power is turned off and the operation is stopped, residual heat remains in the upper plate for a considerable time, thereby causing a safety accident such as a burn in the contact area of the upper plate when the user touches the upper plate .
상기 상판에 남아 있는 잔열에 의하여 화상 등의 안전사고가 발생되지 않도록 [0010] 하기 위하여 대한민국 공개특허공보 제10-2010-0006438호에서는 전기레인지에 상판의 온도를 검출하기 위한 온도센서 및 잔열을 표시하기 위한 발광부를 구비하고, 상기 온도센서가 검출하는 온도가 미리 설정된 온도 이상일 경우에 상기 발광부를 동작시켜 상판에 잔열이 남아 있음을 경보하고 있다.In order to prevent a safety accident such as an image due to the residual heat remaining on the upper plate, Korean Patent Laid-Open No. 10-2010-0006438 discloses a temperature sensor and a residual heat for detecting the temperature of the upper plate in an electric range And when the temperature detected by the temperature sensor is equal to or higher than a preset temperature, the light emitting unit is operated to warn that residual heat remains on the upper plate.
그러나 상기한 종래의 기술은 고가의 마이크로 컴퓨터 등과 같은 제어부를 사용하여 온도센서가 검출하는 상판의 온도를 판단하고, 상판에 잔열이 남아 있다고 판단될 경우에 점등신호를 발생하여 상기 발광부를 점등시키는 것으로서 고가의 제어부를 사용함에 따라 전기레인지의 생산원가를 상승시키게 되는 문제점이 있다.However, the above-mentioned conventional technique judges the temperature of the upper plate detected by the temperature sensor by using a control unit such as an expensive microcomputer and generates a lighting signal when it is judged that residual heat remains in the upper plate, There is a problem that the production cost of the electric range is increased by using an expensive control unit.

In addition, the principles and concepts of the present invention are presented as being most useful and readily explanatory.
따라서 본 발명의 기본 이해를 위한 필요 이상의 자세한 구조를 제공하고자 하지 않았음은 물론 통상의 지식을 가진 자가 본 발명의 실체에서 실시될 수 있는 여러 가지의 형태들을 도면을 통해 예시한다.Accordingly, it is not intended to provide a more detailed structure than is necessary for a basic understanding of the present invention, but it should be understood by those skilled in the art that various forms that can be practiced in the present invention are illustrated in the drawings.
도 1은 본 발명의 잔열 관리장치의 블록도이고, 도 2는 본 발명의 잔열 관리장치의 예시 회로도이다. 도 1 및 도 2를 참조하면, 본 발명의 잔열 관리장치는 온도 검출부(100)와, 온도 판단부(110)와, 잔열 경보 표시부(120)와, 상판 냉각부(130)를 포함하여 구성될 수 있다.FIG. 1 is a block diagram of a residual heat management apparatus of the present invention, and FIG. 2 is an exemplary circuit diagram of a residual heat management apparatus of the present invention. 1 and 2, the apparatus for managing residual heat according to the present invention includes a temperature detecting unit 100, a temperature determining unit 110, a residual heat alarm displaying unit 120, and a top plate cooling unit 130 .
상기 온도 검출부(100)는 제 1 전원단자(Vcc1)에 저항(R1) 및 온도센서(TS)가 직렬 접속되어 상판의 온도에 반비례하는 레벨의 온도 검출전압을 발생하게 구성될 수 있다.The temperature detector 100 may be configured to generate a temperature detection voltage having a level inversely proportional to the temperature of the top plate by connecting a resistor R1 and a temperature sensor TS to the first power terminal Vcc1 in series.
상기 제 1 전원단자(Vcc1)에는 예를 들면, 전기레인지의 동작을 정지시킬 경우에 5V의 동작전력이 인가된다.For example, when the operation of the electric range is stopped, the first power terminal Vcc1 is supplied with the operating power of 5V.
상기 온도센서(TS)는 예를 들면, 전기레인지에 구비된 화구의 중심부의 상판(도면에 도시되지 않았음)에 통상의 방법으로 부착되어 상판의 온도에 따라 저항 값이 가변된다.The temperature sensor TS is attached to a top plate (not shown in the figure) at the center of a furnace provided in the electric range, for example, in a usual manner, and the resistance value varies depending on the temperature of the top plate.
그리고 상기 온도센서(TS)는 상술한 바와 같이 상판에 부착되어 상판의 온도를 검출하되, 상판의 온도가 높을 경우에 저항값이 낮아지고, 온도가 높을수록 저항값이 점차 높아진다.The temperature sensor TS is attached to the top plate to detect the temperature of the top plate, and the resistance value decreases when the temperature of the top plate is high, and the resistance value gradually increases as the temperature increases.
상기 온도 판단부(110)는 상기 온도 검출부(100)의 온도 검출전압과 미리 설정된 기준전압을 비교하여 상판의 잔열 온도가 미리 설정된 기준온도 이상인지의 여부를 판단한다.The temperature determination unit 110 compares the temperature detection voltage of the temperature detection unit 100 with a predetermined reference voltage to determine whether the residual heat temperature of the upper plate is equal to or higher than a predetermined reference temperature.
상기 기준전압은 상판의 잔열에 의하여 사용자가 화상을 입게 되는 등의 안전사고가 발생하지 않는 기준온도에 따른 레벨의 전압으로 설정되는 것으로서 상기 온도 판단부(110)는 예를 들면, 비교기를 사용하여 상판의 잔열 온도가 미리 설정된 기준온도 이상인지의 여부를 판단한다.The reference voltage is set to a voltage of a level according to a reference temperature at which a safety accident such as a user is burned by the residual heat of the top plate. The temperature determination unit 110 uses a comparator, for example, It is determined whether the residual heat temperature of the upper plate is equal to or higher than a preset reference temperature.
상기 잔열 경보 표시부(120)는, 제 1 전원단자(Vcc1)가 직렬 접속된 저항(R2) 및 발광 다이오드(LED)를 순차적으로 통해 상기 온도 판단부(110)의 출력단자에 접속되어 상기 상판에 잔열이 남아 있을 경우에 상기 잔열이 남아 있음을 표시하여 경보한다.The residual heat alarm display unit 120 is connected to an output terminal of the temperature judging unit 110 through a resistor R2 and a light emitting diode LED which are connected in series to a first power supply terminal Vcc1, When there is a residual heat, it indicates that the residual heat remains and warns it.
예를 들면, 상기 발광 다이오드(LED)는 적색 광을 출력하는 것으로서 화구의 주연부에 복수 개가 설치되고, 상기 온도 판단부(110)가 잔열이 남아 있음을 판단할 경우에 상기 발광 다이오드(LED)가 점등되어 상기 상판에 잔열이 남아 있음을 경보한다.For example, the light emitting diodes (LEDs) output red light, and a plurality of light emitting diodes (LEDs) are provided on the periphery of a culvert. When the temperature determination unit 110 determines that residual heat remains, And is warned that residual heat remains on the upper plate.
상기 상판 냉각부(130)는, 잔열이 있는 상판을 빠른 속도로 냉각시키는 것으로서 상기 제 1 전원단자(Vcc1)가 저항(R3)을 통해, 상기 온도 판단부(110)의 출력단자 및 트랜지스터(TR)의 베이스에 접속되고, 트랜지스터(TR)의 에미터는 제 2 전원단자(Vcc2)에 접속되며, 트랜지스터(TR)의 콜렉터는 냉각 팬(F)에 접속된다.The upper plate cooling section 130 rapidly cools the upper plate having the residual heat and the first power terminal Vcc1 is connected to the output terminal of the temperature determination section 110 and the output terminal of the transistor TR The emitter of the transistor TR is connected to the second power supply terminal Vcc2 and the collector of the transistor TR is connected to the cooling fan F. [
상기 제 2 전원단자(Vcc2)에는 예를 들면, 전기레인지의 동작을 정지시킬 경우에 상기 냉각 팬(F)의 정격 동작 전압인 12V의 동작전력이 인가된다.When the operation of the electric range is stopped, for example, the operating power of 12 V, which is the rated operating voltage of the cooling fan F, is applied to the second power supply terminal Vcc2.
이러한 구성을 가지는 본 발명의 잔열 관리장치는 전기레인지를 동작시킬 수 정지시킬 경우에 제 1 전원단자(Vcc1) 및 제 2 전원단자(Vcc2)에 예를 들면, 5V 및 12V의 동작전력이 각기 인가된다.The residual heat management apparatus according to the present invention having such a configuration has a configuration in which, for example, 5 V and 12 V operation power is applied to the first power supply terminal Vcc 1 and the second power supply terminal Vcc 2 when the electric range is stopped for operation do.
이와 같은 상태에서 온도 검출부(100)의 온도센서(TS)는 상판에 남아 있는 잔열의 온도에 따른 저항을 가지게 되고, 상기 온도센서(TS)의 저항은 저항(R1)과 함께 제 1 전원단자(Vcc1)의 전압을 분할하여 온도 검출전압을 발생하며, 발생한 온도 검출전압은 온도 판단부(110)의 비교기의 플러스 입력단자(+)에 인가된다.In this state, the temperature sensor TS of the temperature detector 100 has a resistance according to the temperature of the residual heat remaining on the upper plate, and the resistance of the temperature sensor TS is connected to the first power terminal And the generated temperature detection voltage is applied to the plus input terminal (+) of the comparator of the temperature judging unit 110. The temperature detection voltage is applied to the plus input terminal (+) of the comparator.
상기 온도 판단부(110)의 비교기의 마이너스 입력단자(-)에는, 상판의 잔열에 의하여 사용자가 화상을 입게 되는 등의 안전사고가 발생하지 않는 기준온도에 따른 레벨의 기준전압이 인가된다.A reference voltage of a level corresponding to a reference temperature at which a safety accident such as a user wearing an image due to the residual heat of the top plate does not occur is applied to the minus input terminal (-) of the comparator of the temperature judging unit 110.
그러면, 상기 온도 판단부(110)는, 상기 상판의 온도가 미리 설정된 기준온도 [0037] 이상일 경우에 논리 0의 저전위를 출력하고, 상판의 온도가 미리 설정된 기준온도 이하일 경우에 논리 1의 고전위를 출력하게 된다.The temperature determination unit 110 outputs a low potential of logic 0 when the temperature of the top plate is equal to or higher than a preset reference temperature and outputs a low potential of logic 0 when the temperature of the top plate is lower than a predetermined reference temperature, And outputs the above.
이와 같은 상태에서 상기 상판의 온도가 미리 설정된 기준온도 이상으로서 상기 온도 판단부(110)가 논리 0의 저전위를 출력하게 되면, 전원단자(Vcc1)의 동작전력이 저항(R2) 및 발광 다이오드(LED)를 통해 상기 온도 판단부(110)의 출력단자로 흐르게 된다.In this state, when the temperature of the upper plate is higher than a predetermined reference temperature and the temperature determination unit 110 outputs a low potential of logic 0, the operating power of the power supply terminal Vcc1 is lower than the operating voltage of the resistor R2 and the light emitting diode LED) to the output terminal of the temperature determination unit 110. [
그러면, 상기 발광 다이오드(LED)가 점등되어 예를 들면, 적색 광을 발생하게 된다.Then, the light emitting diode (LED) is turned on to generate, for example, red light.
여기서, 상기 발광 다이오드(LED)는 회구의 주연부에 복수 개가 설치되는 것으로서 상기 화구를 붉게 표시하여 해당 화구의 전열로 인한 안전사고의 발생 위험을 경보하게 된다.Here, a plurality of light emitting diodes (LEDs) are installed at the periphery of the pit, and the pit is displayed in red to warn of the risk of a safety accident due to the heat of the corresponding pit.
또한 상기 온도 판단부(110)가 논리 0의 저전위를 출력하게 제 1 전원단자(Vcc1)의 동작전력이 상판 냉각부(130)의 저항(R3)을 통해 상기 온도 판단부(110)의 출력단자로 흐르게 된다.The operation power of the first power supply terminal Vcc1 is set such that the operating power of the first power supply terminal Vcc1 is lowered to the output of the temperature judging unit 110 through the resistor R3 of the upper plate cooling unit 130, Terminal.
그러면, 트랜지스터(TR)의 베이스에 그의 바이어스 전압 이하가 인가되어 트랜지스터(TR)가 도통상태로 되고, 제 2 전원단자(Vcc2)의 동작전력이 상기 트랜지스터(TR)를 통해 냉각 팬(F)에 인가되어 냉각 팬(F)이 구동되고, 전기 레인지의 상판을 냉각시키게 된다.Then, the bias voltage of the transistor TR is applied to the base of the transistor TR so that the transistor TR is turned on and the operating power of the second power supply terminal Vcc2 is supplied to the cooling fan F through the transistor TR And the cooling fan F is driven to cool the top plate of the electric range.
이와 같이 발광 다이오드(LED)가 점등되어 화구의 잔열로 인한 안전사고의 발생 위험을 경보하고, 또한 냉각 팬(F)을 구동시켜 전기 레인지의 상판을 냉각시키는 상태에서 상기 상판의 온도가 상기 기준온도 이하로 낮아지게 되면, 상기와는 반대로 온도 검출부(100)에서 출력되는 온도 검출전압이 기준전압보다 높아지게 된다.The temperature of the upper plate is lower than the reference temperature (L) in a state in which the light emitting diode (LED) is turned on to warn the risk of occurrence of a safety accident due to residual heat of the firebox, The temperature detection voltage outputted from the temperature detector 100 becomes higher than the reference voltage.
그러면, 상기 온도 판단부(110)는 상기와는 반대로 논리 1의 고전위를 출력하게 된다.Then, the temperature determination unit 110 outputs the high potential of logic 1 as opposed to the above.
상기 온도 판단부(110)가 논리 1의 고전위를 출력함에 따라 상기와는 반대로 잔열 표시부(120)의 발광다이오드(LED)가 점등되지 않게 되어 상기 상판에 잔열이 없음을 알리게 된다.As the temperature judging unit 110 outputs the high potential of logic 1, the light emitting diodes (LEDs) of the residual heat display unit 120 are not turned on to inform the upper panel that there is no residual heat.
또한 상기 온도 판단부(110)가 논리 1의 고전위를 출력함에 따라 상판 냉각부(130)의 트랜지스터(,TR)가 턴 오프되고, 이로 인하여 냉각 팬(F)이 동작하지 않게 되어 더 이상 상기 상판을 냉각시키는 동작을 종료하게 된다.The transistor TR of the upper plate cooling unit 130 is turned off as the temperature determination unit 110 outputs the high potential of the logic 1 so that the cooling fan F does not operate, The operation of cooling the upper plate is terminated.
