전술한 구성을 갖는 종래의 휴대용 조리용기를 사용하는 방법을 설명하면 다음과 같다. A method of using a conventional portable cooking vessel having the above-described configuration will be described as follows.

먼저 하부용기바닥면부(122)에 발열체를 탑재한다.First, a heating element is mounted on the lower container bottom surface portion 122 .

다음에 하부용기(120)에 상부용기(130)를 설치한다. Next, the upper container 130 is installed in the lower container 120 .

다음에 상부용기(130)에 가열하여 익힐 음식물을 담는다.Next, the food to be heated and cooked is placed in the upper container 130 .

다음에 상부용기(130)에 뚜껑(143)을 설치한다.Next, a lid 143 is installed on the upper container 130 .

다음에 물주입구(161)를 통해 발열체수용공간에 물을 주입한다.Next, water is injected into the heating element accommodating space through the water inlet 161 .

다음에 물주입구마개(141)를 주입구폐쇄위치로 이동시켜 물주입구(161)를 폐쇄한다. 물주입구(161)의 폐쇄상태는 마개구속부(150)에 의해 유지된다.Next, the water inlet stopper 141 is moved to the inlet closing position to close the water inlet 161 . The closed state of the water inlet 161 is maintained by the stopper restraint unit 150 .

발열체수용공간에 물이 주입되면 발열체와 물과의 수화반응에 의해 열이 발생하고 이 열에 의해 상부용기(130)에 담긴 음식물이 가열된다.When water is injected into the heating element accommodating space, heat is generated by the hydration reaction between the heating element and water, and the food contained in the upper container 130 is heated by this heat.

그런데 종래의 휴대용 조리용기에 따르면, 발열체수용공간에서 발생한 열이 합성수지로 제작된 상부용기측면부(131)와 상부용기바닥면부(132)를 통해 상부용기(130)에 담긴 음식물에 전달되기 때문에 열효율이 좋지 않다는 문제점이 있었다.However, according to the conventional portable cooking container, the heat generated in the heating element accommodating space is transferred to the food contained in the upper container 130 through the upper container side part 131 and the upper container bottom surface part 132 made of synthetic resin, so the thermal efficiency is high. There was a problem that it wasn't good.
