Why does the Xiaomi Multifunctional IH Rice Cooker make abnormal sounds?

If the Xiaomi Multifunctional IH Rice Cooker make “squeaking” sound during the heat preservation process, please refer to the following details:
1. The principle of IH electromagnetic heating: When the magnetic field of the coil disk detects the pot and during operation, the magnetic field generated by the coil disk cuts the alloy inner pot, which will emit a slight electromagnetic sound. This is a normal phenomenon and is the same as the working principle of an induction cooker.
Therefore, the rice cooker is intermittently heated during the heat preservation process, so there will be intermittent electromagnetic sound during the heat preservation, which is a normal phenomenon;
2. According to the traditional chassis heating principle, the rice cooker needs to adjust the cooking curve by switching on and off the relay during cooking. There will be a slight switching sound during the working process of the relay, which is the normal working principle of the rice cooker. Please feel free to use it.
Note:
1. Please wipe off the water at the bottom of the inner pot when cooking. The rice cooker uses a hot plate to transfer heat energy. When the heat of the heating plate rises and comes into direct contact with the water, the water will boil and evaporate quickly, and a sound of boiling and bursting bubbles will be heard.
Therefore, the rice cooker is intermittently heated during the heat preservation process, so there will be intermittent heating sounds during the insulation, which is a normal phenomenon;
2. The rice cooker will start working after entering the keep warm mode; the keep warm function is detected by the temperature sensor inside the cooker. When the temperature inside the cooker is lower than the keep warm temperature, the rice cooker will start heating, and when the keep warm temperature is reached, the rice cooker will stop heating. Therefore, the rice cooker will work indirectly when keeping warm.
