2. When you plan to cook porridge with a rice cooker, soak the rice first, and then put the rice in after the water is half boiled to prevent the rice soup from overflowing;

4. When cooking porridge, check whether the inner container of the rice cooker is in good contact with the heating plate and whether there are impurities. Impurities will damage the parts of the temperature control switch, and the rice cooker cannot trip. Regularly clean the impurities between the heating plate and the pot body;

Unplug the power supply, cover the air outlet with a wet towel, and don't open the air outlet to the maximum at one time. Don't open it until the air is small. When the porridge is cooked, it should be slightly deflated or it will overflow. When cooking, turn the pressure regulating valve to the closed side. Don't boil the pot in a hurry after cooking, let the pot decompress automatically, and then turn the pressure regulating valve to the deflation side after ten minutes.

Extended data:

The most important thing in choosing a rice cooker is safety. When buying, be sure to check whether the product has 3C logo, including plug and power cord, and then check the product manual. Formal instructions should be printed with product name, trademark, model, rated voltage, frequency, power, manufacturer or seller. The instructions should be printed clearly, and the manufacturer, address, telephone number and maintenance items should be clearly marked. It should also be equipped with a warranty card, packing list and. In addition, it is also necessary to check whether the power cord is double-insulated, and whether the core is greater than or equal to 0.75 square millimeters.

After checking the above items, it is necessary to choose the appearance of the rice cooker. It is best to observe whether the appearance is scratched or deformed from different angles, whether the joints of various parts are smooth, and whether the liner coating is uniform. Carefully check whether the liner coating will fall off, which may cause cancer. The products produced by regular manufacturers basically put an end to this problem, but it is still necessary to check clearly for safety.
