Can an electric rice cooker be used to cook?

The rice cooker is a common household appliance in our lives. The invention of the rice cooker saves us a lot of effort when cooking. Most people choose to use the rice cooker to simmer rice or make porridge because it is very fast and saves time and effort. Some people also choose to use the rice cooker to cook. Can a multi-function electric hot pot cook?

The electric hot pot can be used to stir-fry vegetables. The electric hot pot is a modern cooker that uses a composite bottom welding process and a composite ground pulling welding process. It has high thermal efficiency, long service life, and complete functions: it can be used for frying, deep-frying, steaming, boiling, shabu-shabu, stewing, simmering, braising and other processing. It can not only cook food, but also keep it warm. It is clean and hygienic to use, has no radiation, saves time and effort, and is one of the indispensable tools for modern housework.

Electric cooker, also known as electric pot, electric rice cooker, is a cooking utensil which converts electrical energy into internal energy. It is easy to use, clean and hygienic, and has multiple operating functions such as steaming, boiling, stewing and simmering food. Now it has become a daily household appliance. The invention of the rice cooker has reduced the time many families spend on cooking. The world's first electric rice cooker was invented by Japanese Masaru Ibuka at the Tokyo Telecommunications Engineering Company in 1950. Common rice cookers are divided into three categories: automatic keep-warm type, timed keep-warm type, and new microcomputer-controlled type.

The working principle of the rice cooker is shown in the figure. Place the inner pot filled with food on the heating plate so that its bottom fits into the temperature-limiting medium-temperature sensitive soft magnet in the center of the heating plate. When the piano key switch is pressed, the permanent magnet below the soft magnet rises and contacts the soft magnet. At this time, the pot has not yet heated up, and the soft magnet is below the Curie temperature, showing good ferromagnetism, and can be magnetized by the permanent magnet and held at a high point. The soft magnet at the highest point drives the internal lever to connect the upper and lower contacts of the circuit, the heating element is energized and generates heat, and the food in the pot is heated up. When the temperature of the bottom of the inner pot reaches 103±2℃ (this is the Curie temperature of the soft magnet), the soft magnet immediately senses and loses its magnetism, and falls from the high point under the combined action of gravity and the internal spring, thereby driving the lever mechanism to disengage the upper and lower contacts of the circuit, disconnecting the circuit.

The electric heating element no longer generates heat, thus achieving the purpose of temperature limiting. However, the heating plate is still in a high-temperature state at this time, and its heat capacity is large, so it can continue to heat the food in the pot for a period of time until the food is cooked. In order to maintain the food at an appropriate temperature, some rice cookers are also equipped with a low-power heating circuit, and their operating temperature is controlled by a bimetallic thermostat.
