Description

전기밥솥의 보습장치Moisturizer of Electric Rice Cooker

본 발명은 전기밥솥의 보습장치에 관한 것으로서, 더욱 상세하게는 보온시 시간경과에 따른 수분감소를 방지하므로써 밥솥의 보온성능을 향상시킬 수 있도록 한 것이다.The present invention relates to a moisturizing device of an electric rice cooker, and more particularly, to improve the warming performance of the rice cooker by preventing water from decreasing with time elapsed during warming.

종래에는 제1도에 나타낸 바와 같이, 전기밥솥 몸체(la)내부의 오븐(6)에 취사를 위한 쌀과 물을 알맞게 조절하여 넣은 후, 뚜껑(2a)을 닫고 전원이 공급된 상태에서 취사기능을 수행하는 버튼(도시는 생략함)을 선택하면 밥솥밑면의 히터가 발열하여 밥솥 내부의 쌀이 익게 되므로써 취사기능이 수행된다.Conventionally, as shown in Figure 1, after adjusting the rice and water for cooking in the oven (6) inside the rice cooker body (la), close the lid (2a) and cooking function in the state of power supply If you select the button (not shown) to perform the heating of the bottom of the rice cooker heats and cooks the rice inside the cooker by performing the cooking function.

또한, 취사기능의 수행이 완료된 후에는 자동으로 보온기능 모드로 밥솥 내부의 온도를 일정하게 유지할 수 있도록 온도센서 및 히터가 작동하므로써 취사가 완료된 밥의 보온이 수행된다.In addition, after the completion of the cooking function is carried out by the temperature sensor and the heater to automatically maintain the temperature inside the cooker in the warming function mode automatically, the warming of the cooked rice is performed.

이때, 밥솥 내부의 온도를 일정하게 유지시키는 방법은 온도센서를 이용하여 밥솥 내부의 온도를 검지하여, 검지된 온도는 마이콤(도시는 생략함)에 전달되고,상기 마이콤은 검지온도(Ts)와 유지기준온도(T)를 비교하여 검지온도(Ts)가 유지기준온도(T)보다 높을 때( Ts > T )에는 히터를 오프시키며, 유지기준온도(T)보다 검지온도(Ts)가 낮을 때( Ts < T )에는 히터를 온시켜 열을 가하므로써 일정한 온도가 유지되도록 한다At this time, the method of maintaining a constant temperature inside the cooker detects the temperature inside the cooker using a temperature sensor, the detected temperature is transmitted to the microcomputer (not shown), the micom is the detection temperature (Ts) and When the detection temperature (Ts) is higher than the holding reference temperature (Ts> T) by comparing the holding reference temperature (T), the heater is turned off, and when the detecting temperature (Ts) is lower than the holding reference temperature (T). Heat the heater to (Ts <T) to maintain a constant temperature by applying heat

그러나, 이와 같은 종래의 전기밥솥은 몸체(la)의 내부를 일정온도로 유지시키기 위한 히터가 온도센서의 신호를 받은 마이콤의 제어에 의해 온 또는 오프 동작을 반복 수행하게 되는데, 히터의 온동작시 밥솥내부의 밥에는 열이 가해지므로 밥에 함유된 수분은 증발되어 전기밥솥의 뚜껑(2a)에 형성된 증기배출구(7)를 통해외부로 빠져나가게 됨에 따라 밥의 건조가 진행되고 이와 함께 밥이 누렇게 변색되며 쿰쿰한 냄새가 발생하므로 인해 사용자에게 불쾌감과 불편함을 야기시키는 등의 문제점이 있었다.However, in the conventional electric rice cooker, the heater for maintaining the inside of the body (la) at a constant temperature is repeatedly performed on or off operation by the control of the microcomputer received a signal of the temperature sensor, during the on operation of the heater Since heat is applied to the rice inside the rice cooker, the moisture contained in the rice is evaporated, and the food is dried out as it passes out through the steam outlet 7 formed in the lid 2a of the rice cooker. There is a problem such as causing discoloration and a sour smell caused by the user discomfort and discomfort.

본 발명은 상기한 제반 문제점을 해결하기 위한 것으로 전기 밥솥의 취사기능 수행시 증발되는 물을 저장하고 검출된 습도에 따라 히터로 저장된 물을 가열하도록 하여 보온의 진행시 보습기능이 함께 이루어지도록 하므로써 밥의 건조나 변색 및 냄새의 발생을 효과적으로 방지할 수 있는 전기밥솥의 보습장치를 제공하는데 그 목적이 있다.The present invention is to solve the above problems by storing the water to be evaporated when performing the cooking function of the electric cooker and to heat the water stored in the heater according to the detected humidity to ensure that the moisturizing function is carried out with the progress of the insulation The purpose is to provide a moisturizing device of an electric rice cooker that can effectively prevent the drying or discoloration and the occurrence of smell.

상기한 목적을 달성하기 위해 본 발명은 몸체에 개폐 가능하게 설치된 뚜껑에 부착되며 몸체 내의 습도를 검출하기 위한 습도검출기와, 상기 습도검출기에서검출된 습도가 설정치보다 낮을 때 물저장고에 저장된 물이 수증기화되도록 물을 가열하여 주는 가열히터로 구성된 전기밥솥의 보습장치이다.In order to achieve the above object, the present invention is attached to a lid installed to open and close the body and the humidity detector for detecting the humidity in the body, the water stored in the water reservoir when the humidity detected in the humidity detector is lower than the set value water vapor Moisturizing device of electric rice cooker consisting of a heating heater that heats the water so that it becomes.

이하, 본 발명의 일실시예를 첨부도면 제2도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명을 일부 절개하여 나타낸 종단면도로서, 전기밥솥의 몸체(1)상에 개폐 가능하게 설치된 뚜껑(2)의 하부에 몸체(1)내의 습도를 검출하기 위한 습도검출기(3)가 부착되고, 물저장고(4) 일측의 몸체(1)에는 습도검출기(3)에 검출된 수증기량에 따라 물저장고(4)에 저장된 물을 가열하기 위한 가열히터(5)가 설치되어 구성된다.2 is a longitudinal cross-sectional view showing a part of the present invention, the humidity detector (3) for detecting the humidity in the body (1) in the lower part of the lid (2) provided to be opened and closed on the body (1) of the rice cooker The body 1 of one side of the water reservoir 4 is attached, and a heating heater 5 is installed to heat the water stored in the water reservoir 4 according to the amount of water vapor detected by the humidity detector 3.

이와 같이 구성된 본 발명은 제2도에 나타낸 바와 같이, 전기밥솥의 몸체(1)내의 오븐(6)에 물과 쌀을 알맞게 조절하여 넣은 후 뚜껑(2)을 닫고 전원을 공급한 상태에서 취사기능을 수행하는 버튼을 선택하면 몸체(1)의 밑면에 장착된 히터(도시는 생략함)가 발열하여 취사기능이 수행된다.The present invention configured as described above, as shown in Figure 2, after adjusting the water and rice in the oven (6) in the body (1) of the electric rice cooker to close the lid (2), the cooking function in the state of supplying power Selecting a button to perform a heater (not shown) mounted on the bottom of the body 1 generates heat to perform the cooking function.

이때, 취사기능이 수행되면서 증발되는 수증기의 일부는 뚜껑(2)에 형성된 증기배출구(7)를 통해 빠져 나가게되며 나머지는 밥솥의 몸체(1) 상단 둘레로 파여진 유도홈(8) 및 내부공간을 통해 물저장고(4)로 가서 냉각되어 모이게 된다.At this time, a portion of the vapor evaporated while the cooking function is performed is passed through the steam outlet (7) formed in the lid (2) and the rest of the guide groove (8) and the inner space dug around the top of the body (1) of the cooker Go to the water reservoir (4) through the cooling is collected.

또한, 취사기능이 완료된 후에는 자동으로 보온기능 모드로 전환되어 밥솥내부의 온도가 일정온도를 유지할 수 있도록 온도센서에서 검출된 신호에 의해 마이콤은 몸체(1) 밑면의 히터를 반복적으로 온 또는 오프시켜 보온기능이 수행되도록 한다.In addition, after the cooking function is completed, the microcomputer automatically turns on or off the heater on the bottom of the body 1 by a signal detected by the temperature sensor so that the temperature inside the cooker is maintained at a constant temperature automatically. To keep warm function.

이와 같이, 마이콤의 제어에 의해 히터가 온 또는 오프되면서 보온기능이 수행되는 도중 히터의 온동작시에는 몸체(1)내부의 밥에는 열이 가해져 밥에 함유되어 있는 수분이 증발하게 되는데, 이 때 전기밥솥의 뚜껑(2) 하부에 설치된 습도검출기(3)는 보온의 진행에 따른 밥솥 내부의 습도량을 검출하여 마이콤에 검출신호를 보내게 된다.As such, when the heater is turned on or off under the control of the microcomputer and the heating function is performed, the rice inside the body 1 is heated to evaporate the moisture contained in the rice. The humidity detector 3 installed below the lid 2 of the electric rice cooker detects the amount of humidity inside the rice cooker according to the progress of warming and sends a detection signal to the microcomputer.

따라서, 마이콤은 습도검출기(3)의 검출신호를 판단하여 밥솥내부이 습도가 설정값 이하일 경우에는 물저장고(4)측면 몸체(1)에 설치된 가열히터(5)를 작동시켜 저장된 물을 가열시켜 밥솥 내부로 수증기를 공급하여 보충해주게 되고, 습도검출기(3)의 검출값이 설정값과 일치하면 마이콤의 제어에 의해 가열히터(4)가 오프되어 수증기의 공급을 중단시킨다.Therefore, the microcomputer determines the detection signal of the humidity detector 3, and when the inside of the cooker has a humidity lower than or equal to the set value, the microcomputer operates the heating heater 5 installed in the body 1 of the water reservoir 4 to heat the stored water to cook the rice. The water supply is supplemented by supplying water vapor, and when the detected value of the humidity detector 3 matches the set value, the heating heater 4 is turned off by the control of the microcomputer to stop the supply of the water vapor.

이상에서와 같이, 본 발명은 전기밥솥의 몸체(1)측면에 취사시 증발되는 물을 저장하는 물저장고(4)를 장착하고 그 측면에는 마이콤에 의해 동작하는 가열히터(4)를 설치하여 밥솥의 보온기능이 수행되는 동안 보습기능이 함께 이루어지도록 함으로서 밥의 건조를 방지하고 냄새 및 변색을 효과적으로 억제할 수 있으며, 사용자에게 먹기 좋은 상태의 밥을 제공할 수 있게 된다.As described above, the present invention is equipped with a water reservoir (4) for storing the water evaporated when cooking on the side of the body (1) of the rice cooker and by installing a heating heater (4) operated by the microcomputer on the side of the rice cooker By maintaining the moisturizing function while the warmth function of the can prevent the drying of the rice and effectively suppress the smell and discoloration, it is possible to provide a user of the rice in a good state to eat.
