In order to prevent the danger caused by too high temperature, the temperature controller is installed in the all-round instant pot, which can control the temperature within a safe and suitable temperature range to prevent the product from being damaged and dangerous due to too high temperature. The thermostat has been adjusted when leaving the factory, and the temperature can be controlled within the normal temperature range. All-purpose instant hot pot automatically turns off power when it can't be used normally, because the temperature adjusted by the thermostat is too low to reach the normal use temperature, so it automatically turns off power.
