The amps it draws depends on how big it is. Typically 2-12 amps. Check for a manufacturer's plate that shows the wattage Most of the load in a rice cooker is a resistive heating element, so the amperage will be quite close to the wattage divided by the voltage (220 here).
The maximum current capacity of a 220V 20 amp outlet is 20 amps.

The recommended wire size for a 220v 20 amp circuit is typically 12-gauge wire.
The recommended wire size for a 220v 30 amp circuit is typically 10 gauge wire.
The appropriate wire size for a 20 amp 220v circuit is typically 12-gauge wire.
The appropriate wire size for a 220v 30 amp circuit is typically 10 gauge wire.
The recommended wire size for a 60 amp 220v circuit is typically 6-gauge wire.
Amp draw is always combined. 220V is uncertain if it is three phase or not, because there are both one phase and three phase applications of the 220V motor. In any case, the answer is always "combined".
For a 220V 30 amp circuit, a 10-gauge wire should be used to ensure safe and efficient electrical conductivity.
For a 30 amp 220v circuit, a 10-gauge wire should be used to ensure safety and proper functioning of the circuit.
For a 20 amp 220v circuit, a 12-gauge wire should be used to ensure safety and proper functioning of the circuit.
For a 220V 20 amp circuit, the appropriate wire size is typically 10 AWG (American Wire Gauge) for copper conductors.
