Description
본 발명은 열판을 사용하지 않고 쌀, 보리 등의 취사재료가 담긴 내솥용기에 직접 전기에너지를 공급하여 가열하는 전기밥솥에 관한 것으로서, 보다 상세히는 전도성 발열체를 바닥에 부착한 세라믹 또는 금속제 내솥용기의 상기 전도성 발열체에 마그네틱이나 레바접점, 또는 스프링 밀착이나 솔레노이드 접점의 접촉방식으로 직접 전기에너지를 공급하여 내솥용기를 가열하는 직접가열식 전기밥솥에 관한 것이다.The present invention relates to an electric rice cooker which directly supplies electric energy to an inner pot container containing cooking materials such as rice and barley without using a hot plate, and more specifically, to a ceramic or metal inner pot container having a conductive heating element attached to the bottom thereof. It relates to a direct heating type electric rice cooker to heat the inner pot container by directly supplying electrical energy to the conductive heating element by a magnetic or lever contact, or a spring contact or solenoid contact method.
도 7은 흔히 볼 수 있는 통상 구조의 전기밥솥을 도시한 것으로서, 밥솥의 외면을 형성하는 외솥(44)과, 외솥에 안착되는 내솥(45)과, 이들을 덮는 뚜껑(46)과, 상기 내솥에 담긴 취사재료를 가열하는 히터로 구성되어 있다.7 illustrates an electric rice cooker having a common structure, which is commonly seen, an outer pot 44 forming an outer surface of the rice cooker, an inner pot 45 seated on the outer pot, a lid 46 covering them, and the inner pot. It consists of a heater that heats the cooking material.
상기 구성의 종래 전기밥솥에 있어서, 히터를 내장한 열판(48)이 위치되는 곳은 내솥(45)이 안착되는 외솥(44)의 안쪽면 바닥이다.In the conventional electric rice cooker of the above configuration, where the hot plate 48 with a heater is located is the inner bottom of the outer pot 44 on which the inner pot 45 is seated.
따라서, 상기 히터가 내장된 열판(48)에 의하여 내솥(45)이 가열되면, 상기 내솥 내부의 취사재료와 물이 가열되어 취사가 이루어진다.Accordingly, when the inner pot 45 is heated by the hot plate 48 having the heater built therein, the cooking material and water inside the inner pot are heated to cook.
이러한 가열방식을 간접가열방식이라고 칭하는데, 내솥(45) 바닥면의열판(48)에 의해 내솥이 가열되는 과정에서, 열전달 효율이 90%정도 밖에 안되고, 상기 내솥 내부의 상·하 온도의 편차와, 상기 내솥과 열판의 접촉상태에 따라 효율이 크게 달라지는데, 열판과 내솥 사이에 이물질이 묻어 있는 경우 효율은 반 이상으로 떨어질 수 있다.Such a heating method is called an indirect heating method. In the process of heating the inner pot by the heating plate 48 on the bottom of the inner pot 45, the heat transfer efficiency is only about 90%, and the difference between the upper and lower temperatures inside the inner pot. And, the efficiency is greatly changed depending on the contact state of the inner pot and the hot plate, the efficiency may drop to more than half if foreign matter is buried between the hot plate and the inner pot.
특히, 내솥의 바닥면이 원형인 경우, 내솥에 밀착되는 형태로 열판을 가공하기가 어렵고, 더욱이 취사 초기에는 열판과 내솥의 접촉상태가 좋다 하더라도 내솥을 가열하는 동안, 열판과 내솥이 각각 열 팽창하여 이들의 접촉위치가 변동되거나 혹은 접촉이 불량해지는 단점이 있다.In particular, when the inner surface of the inner pot is circular, it is difficult to process the hot plate in the form of being in close contact with the inner pot, and furthermore, in the initial cooking period, the hot plate and the inner pot are thermally expanded while heating the inner pot, even if the contact state between the hot plate and the inner pot is good. Therefore, there is a disadvantage that their contact position is changed or the contact is poor.
또한, 후술하는 바에 의해 더욱 분명해지겠지만, 내솥(45)이나 뚜껑에 히터를 내장시켜, 상기 내솥과 뚜껑이 바로 열원이 되는 종래의 직접가열식 전기밥솥에 있어서도, 가열 후 열원인 내솥의 팽창에 대응하여야 하며, 특히 히터를 내장해야 하는 내솥의 설계가 까다롭다는 단점이 있다.In addition, as will be apparent from the following description, in the conventional direct heating type rice cooker in which the inner pot and the lid are a heat source by embedding a heater in the inner pot 45 or the lid, the expansion of the inner pot, which is a heat source after heating, must be supported. In particular, there is a drawback in that the design of the inner pot that needs to include a heater is difficult.
첨부도면중 도 8은, 앞에서 간단히 언급한 종래의 직접가열식 전기밥솥의 구성을 나타낸 도면으로서, 열전도성이 낮은 재료로 만든 내솥(45) 속의 취사재료(곡물류+물)를 균일하게 가열하기 위해, 전기밥솥의 뚜껑(46)의 안쪽면 일측에 다수개의 막대형 히터(50)를 설치하여 구성됨을 알 수 있다.8 is a view showing the configuration of the conventional direct heating type electric rice cooker briefly mentioned above, in order to uniformly heat the cooking material (grains + water) in the inner pot 45 made of a low thermal conductivity material, It can be seen that a plurality of rod-type heaters 50 are installed on one side of the inner side of the lid 46 of the rice cooker.
이러한 구조의 직접가열식 전기밥솥은, 열판을 이용한 간접가열식 전기밥솥에 비해 열효율이 높고 또한 맛있게 취사된다는 장점이 있는 반면, 열팽창 등을 고려해야 함으로 내솥의 설계가 복잡해진다는 단점이 있다.The direct heating type electric rice cooker having such a structure has the advantage of being higher in heat efficiency and delicious than the indirect heating type electric rice cooker using a hot plate, but has a disadvantage in that the design of the inner pot is complicated by considering thermal expansion and the like.
또한, 특별히 도시하지는 않았으나, 고주파에 의한 유도가열형(IH 방식) 전기밥솥의 경우, 표면효과를 유발하기 위해서 내솥의 표면에 주사하는 고주파수의 자장이 외부로 유출되어, 열효율이 나쁘다는 단점이 있으며, 회로구성이 복잡하고 이에 의해 반도체의 전력손실도 약 15%에 달할 뿐 아니라, 여러 부품의 구성에 의한 불량도 높은 편이다.In addition, although not specifically shown, induction heating type (IH type) electric rice cooker by high frequency, the magnetic field of the high frequency injected to the surface of the inner pot is leaked to the outside in order to cause the surface effect, there is a disadvantage that the thermal efficiency is bad. In addition, the circuit configuration is complicated, and the power loss of the semiconductor is about 15%, and the defect caused by the configuration of various components is also high.
본 발명은 상기한 바와 같은 종래 간접 및 직접가열식 전기밥솥의 문제점을 개선하기 위해 안출된 것으로서, 내솥용기의 바깥쪽 바닥면에 전도성 발열체를 부착하여 이 전도성 발열체에 다양한 접촉방식의 전원공급장치로 전기에너지를 공급하여, 상기 내솥용기를 직접가열함으로써 취사가 이루어지게 하는 전기밥솥을 제공함에 그 목적이 있다.The present invention has been made in order to improve the problems of the conventional indirect and direct heating type rice cooker as described above, by attaching a conductive heating element to the outer bottom surface of the inner pot container electric power to the conductive heating element in a variety of contact type power supply device It is an object of the present invention to provide an electric rice cooker for supplying energy and cooking by directly heating the inner pot container.
