[0044] Refrigeration sheet: installed on the side wall of the rice cooker. When the external environment temperature is high, the refrigeration sheet is activated to continuously reduce the temperature in the pot. The refrigeration sheet is generally installed on the bottom or side wall of the rice cooker and connected to the heat sink. The heat absorbed is transferred to the external environment through the heat sink. The refrigeration sheet cools the water and rice in the pot through the heat exchange effect of the inner pot.

[0045] Heat sink: It is set on the outer shell 2 or the bottom of the rice cooker to enhance the heat exchange efficiency of the cooling fins, help release excess heat by increasing the surface area, and cooperate with the cooling fins to transfer the heat in the pot to the external environment to prevent the temperature in the pot from rising. The heat sink is usually made of aluminum alloy or other high thermal conductivity materials to improve the efficiency of heat dissipation.
[0046] When the rice cooker is in the reservation mode, the temperature sensor will monitor the temperature in the pot in real time and transmit it to the thermostat. If the temperature exceeds the set low temperature range, the thermostat will start the refrigeration plate to start cooling. When the temperature in the pot is lower than the set range, the module will automatically adjust to "keep warm" or "standby" mode to avoid excessive cooling. The temperature sensor will continue to monitor the environment in the pot to ensure that the temperature remains stable.
[0047] Humidity regulation and moisture retention module: used to control the humidity inside the rice cooker, ensure that the humidity of the rice water in the pot is kept in the optimal range, and prevent the rice from drying out or fermenting.
