본 고안은 전기보온밥솥의 증기방출용 증기구에 관한 것이다.The present invention relates to a steam outlet for steam release of the electric thermal cooker.
더욱 구체적으로는 밥을 지을 때에는 전기밥솥 내부에서 발생되는 고온의 수증기를 배출하고 밥을 보온시킬 때에는 고온의 열이 외부로 유출되는 것을 방지하도록 폐쇄되는 전기보온밥솥 증기구에 관한 것이다.More specifically, when cooking rice discharges the high temperature steam generated in the inside of the rice cooker and when the rice is insulated to the electric steam cooker closed to prevent the high temperature heat to flow out.
종래에 전기를 사용하여 열을 발생시켜 밥을 짓는 전기보온밥솥에서는, 밥을 짓는 과정에서 고온의 수증기가 배출되었다. 즉, 쌀을 덮고 있는 물은 밥솥 하부에 설치된 가열용 히터에 의하여 비등점 이상으로 가열된다.Conventionally, in an electric thermal rice cooker which generates heat by using electricity to cook rice, hot steam is discharged in the process of cooking rice. That is, the water covering the rice is heated above the boiling point by the heating heater installed in the lower portion of the rice cooker.
이렇게 가열된 물은 더욱 가열되어 기화되며 이렇게 기화된 수증기는 전기 보온밥솥의 뚜껑 표면에 형성된 공기방출용 증기구를 통하여 외부로 배출되었다.The heated water is further heated and vaporized, and the vaporized water vapor is discharged to the outside through an air discharge steam port formed on the lid surface of the electric rice cooker.
그러나 상기 공기방출용 증기구는 항시 개방 상태로서 밥을 짓는 때에는 문제가 되지 않지만 밥을 다 지은 후에 보관하는 때에는 공기방출용 증기구를 통하여 내부의 열이 외부로 배출되어 에너지 낭비의 한 요인이 되었다.However, the air-discharge steam port is always open and does not matter when cooking rice, but when it is stored after cooking, internal heat is discharged to the outside through the air-discharge steam port, which causes a waste of energy.
즉, 상기 공기방출용 증기구는 일반적으로 개방 상태로 놓아 두거나 또는 수지 볼(resin ball)로서 제조되므로 열에 의한 변형이 용이하며 온도 변화가 심한 전기보온밥솥에서는 효과적으로 보온을 할 수 없는 원인이 되었다.That is, the air discharge steam sphere is generally left in an open state or manufactured as a resin ball (resin ball), so it is easy to deform by heat, causing a temperature can not be effectively maintained in an electric thermal cooker severe temperature changes.
본 고안자는 상기와 같은 문제점을 해결하기 위하여 본 고안을 하기에 이른 것이다.The present inventors have come to the present invention to solve the above problems.
즉, 열에 의하여 가열되면 그 형상이 변화하지만 가열원이 제거되면 다시 본래의 형상으로 복귀하는 형상기억 합금을 채용하여 밥을 지을 때에는 증기배출구를 개방시키고 밥을 보온할 때에는 증기배출구를 폐쇄하여 전기보온밥솥의 열효율을 극대화시킨 것이다.That is, the shape changes when heated by heat, but when the heating source is removed, the shape memory alloy is adopted to return to the original shape.The steam outlet is opened when the rice is cooked, and the steam outlet is closed when the rice is kept warm. It is to maximize the thermal efficiency of the rice cooker.
본 고안은 종래 전기보온밥솥 등의 공기방출용 증기구를 효과적으로 개폐하여 보온효과를 증대시키는 것을 목적으로 한다.The present invention aims to effectively open and close the steam outlet for air discharge such as conventional electric rice cooker to increase the warming effect.
이러한 목적을 달성하기 위한 수단으로서 본 고안의 보온밥솥 증기구는, 상부면에 공기방출구멍(14)이 형성되어 있고, 그 상단 측면에 증기배출구(28)가 형성되어 있는 중공의 원통형으로 형성되어진 제1부재(16)와, 하단부에 원판이 형성되어져 있으며, 상기 원판으로부터 상방으로 향하여 돌출되어진 원통형의 삽입부(24)를 가지며, 상기 삽입부(24)가 상기 제1부재의 내부로 삽입되어지는 제2부재(22)와, 상기 제1부재(16)가 삽입될 수 있는 제1부재수납구멍(26)이 형성되어져 그 내부로 제1부재(16)와 제2부재(22)가 삽입되어지도록 형성되어진 원통형의 제3부재(18) 및 상기 제1부재(16)의 내부에 삽입되어 상기 제1부재(16)와 이에 삽입되는 상기 제2부재(22)의 수납부(24) 사이에 개재 되어지는 형상기억합금(20)으로 구성됨을 특징으로 한다.As a means for achieving the above object, the thermostat rice cooker steam sphere of the present invention, the air discharge hole 14 is formed on the upper surface, the steam outlet 28 is formed in a hollow cylindrical shape formed on the upper side One member 16 and a disc is formed at the lower end, and has a cylindrical insert 24 protruding upward from the disc, wherein the insert 24 is inserted into the first member. The second member 22 and the first member receiving hole 26 into which the first member 16 can be inserted are formed, and the first member 16 and the second member 22 are inserted therein. Between the first member 16 and the receiving portion 24 of the second member 22 inserted into the cylindrical first third member 18 and the first member 16. Characterized in that it consists of a shape memory alloy 20 is interposed.
이하 첨부된 도면을 참고하여 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
본 고안은 전기보온밥솥의 수증기 배출용 구멍을 개폐하기 위한 개폐부재가 사용된 증기구에 관한 것으로, 상기 개폐부재는 형상기억합금을 사용하여 80℃ 이상에서 수증기가 발생되면 형상이 변화하여 제1부재(12)를 상방으로 이동시켜 증기배출구(28)를 노출시켜 이동로를 형성하고, 평상시, 즉 밥의 보온상태에서는 증기배출구(28)를 은닉하여 이동로를 폐쇄하여 내부의 고열이 외부로 방출되는 것을 방지한다.The present invention relates to a steam port using an opening and closing member for opening and closing the steam discharge hole of the electric thermal cooker, the opening and closing member is changed in shape when water vapor is generated at 80 ℃ or more using a shape memory alloy 1 The member 12 is moved upward to expose the steam outlet 28 so as to form a moving path. Normally, in the warm state of the rice, the steam outlet 28 is concealed to close the moving path so that the internal high heat is transferred to the outside. Prevent release.
제1도에 도시된 것은 종래의 증기구(2)의 외부 사시도이다. 도시된 바와 같이 상부측에는 증기방출구멍(4)이 형성되어 있으며, 그 위에는 구멍(6)이 형성되어 있다. 상기 구멍(6)은 원형으로서 증기 방출량의 조절용이다.Shown in FIG. 1 is an external perspective view of a conventional vapor port 2. As shown, the vapor discharge hole 4 is formed in the upper side, and the hole 6 is formed thereon. The hole 6 is circular and is used for adjusting the amount of vapor discharge.
상기 증기구(2)는 일체로 되어 있으며 그 내부에는 공간을 형성하여 발생된 증기는 어떠한 정지수단을 거치지 않고 직접적으로 대기중으로 방출되었다. 따라서 밥을 짓는 과정에서 발생되는 고온의 증기 유출에는 효과가 있지만 밥을 보온하는 과정에서는 열의 낭비 요인이 되었다.The steam port 2 is integrated and forms a space therein, and the steam generated is discharged directly into the atmosphere without passing through any stop means. Therefore, it is effective for the high temperature steam outflow generated during the cooking process, but was a waste of heat during the warming process.
본 고안에 의하면, 제2도에 도시된 바와 같이, 증기구(12)는 외부로는 2부분, 즉 제1부재(16)와 제3부재(18)가 노출된다. 제1부재(16)에는 상단 표면에 공기방출구멍(14)이 형성되어 있으며, 제2도에서 도시된 바와 같이 평상시에는 하부로 감추어져 표시되지 않는 증기배출구(28)가 형성되어 있다. 이것은 형상기억합금에 의하여 야기되는 초기 상태이다. 상기 증기배출구(28)는 대칭으로 두개가 형성되어 있다.According to the present invention, as shown in FIG. 2, the steam port 12 is exposed to two parts, that is, the first member 16 and the third member 18 to the outside. In the first member 16, an air discharge hole 14 is formed in the upper surface, and as shown in FIG. 2, a steam outlet 28 is formed which is not hidden and displayed normally. This is the initial state caused by the shape memory alloy. Two vapor outlets 28 are formed symmetrically.
또한 상기 제3부재(18)는 제1부재(16)를 수납하고 있으며 전기보온밥솥에 취부된다.In addition, the third member 18 accommodates the first member 16 and is mounted in an electric rice cooker.
제3도에 도시된 것은 상기 증기구(12)의 분리 사시도이다. 도시된 바와 같이 제1부재(16)의 증기배출구(28)가 원통형의 측면에 형성되어 있으며 그 내부에는 스프링 형상의 형상기억합금(20)이 삽입, 고정된다.Shown in FIG. 3 is an exploded perspective view of the steam port 12. As shown, the steam outlet 28 of the first member 16 is formed on the side of the cylindrical shape, the spring-shaped shape memory alloy 20 is inserted and fixed.
제1부재(16)의 하부에는 제2부재(22)가 위치한다. 상기 제2부재(22)는 상기 제1부재(16)의 내부로 삽입되는 돌출부(24)를 가지고 있다. 이 돌출부(24)는 상기 형상기억합금(20)을 고정시켜 내부에서 이동하는 것을 방지한다. 완전히 결합되면 제1부재(16)와 제2부재(22)의 하단부는 밀착된다. 이렇게 일체화된 제1부재 및 제2부재는 다시 제3부재(18)의 내부에 삽입된다. 이때 형상기억합금(20)의 상태는 최대 수축 상태로 설정된다.The second member 22 is positioned below the first member 16. The second member 22 has a protrusion 24 inserted into the first member 16. The protruding portion 24 fixes the shape memory alloy 20 to prevent it from moving inside. When fully coupled, the lower ends of the first member 16 and the second member 22 are in close contact with each other. The first member and the second member thus integrated are inserted into the third member 18 again. At this time, the shape memory alloy 20 is set to the maximum contraction state.
밥을 짓기 시작하여 온도가 지속적으로 상승하여 약 80℃ 정도가 되면 제1부재(16)의 증기배출구(28) 내부에 삽입된 개폐부재는 팽창되어 상기 제1부재(16)를 상승시킨다.When cooking starts and the temperature continuously rises to about 80 ° C., the opening / closing member inserted into the steam outlet 28 of the first member 16 is expanded to raise the first member 16.
이에 따라서 제2도에 도시된 바와 같이 제3부재(18)에 형성되어 있지만 보온 상태에서 제1부재수납구멍(26)에 가리워져 있던 증기배출구(28)가 노출되고, 증기는 이 증기배출구(28)를 통하여 외부로 배출된다. 즉, 내부 온도가 100℃ 이상이 되어 하부면에 가까이 있던 물이 기화되면 이 수증기는 증기배출구(28)를 통하여 외부로 유출된다.As a result, as shown in FIG. 2, the steam outlet 28, which is formed in the third member 18 but is hidden by the first member storage hole 26 in a warm state, is exposed, and the steam outlet 28 is exposed. It is discharged to outside through). That is, when the internal temperature reaches 100 ° C. or more and the water near the bottom surface is vaporized, the water vapor flows out through the steam outlet 28.
또한, 상기 공기방출구멍(14)은 항시 개방되어져 있어 전기밥솥의 내부가 완전히 밀폐되는 것을 방지하여 완전밀폐로 인한 밥솥내부의 기압의 증가 등을 예방할 수 있도록 하는 역할을 한다.In addition, the air discharge hole 14 is always open to prevent the inside of the rice cooker is completely sealed and serves to prevent the increase in the air pressure inside the rice cooker due to the complete sealing.
상기한 바와 같이 본 고안은 전기보온밥솥 등의 공기 방출구를 효과적으로 개폐하여 보온 효과를 증대시켜서 일정 온도 이상이 되면 형상이 변형되어 수증기가 이동하는 통로를 형성하도록 구성된 것을 특징으로 한다.As described above, the present invention is characterized in that it is configured to form a passage through which the water vapor is deformed when the temperature is above a predetermined temperature by effectively opening and closing the air outlet such as an electric heat cooker to increase the warming effect.
본 고안은 기재된 구체예에 대해서만 상세히 설명되었지만 본 고안이 속하는 분야의 당업자에게는 본 고안의 사상과 범위내에서 변형이나 변경이 가능하고 이러한 변경이나 변형은 첨부된 실용신안등록청구의 범위에 속한다 할 것이다.Although the present invention has been described in detail only with respect to the described embodiments, those skilled in the art to which the present invention belongs may be modified or modified within the spirit and scope of the present invention, and such changes or modifications fall within the scope of the appended utility model registration claims. .
