And step S3, washing rice according to the rice washing warm water after the injection of the rice washing warm water is finished.

Specifically, after the injection of the warm water for washing rice is completed, the rice is soaked in the warm water for washing rice, dust and impurities attached to the surface of the rice can be cleaned in a rice washing mode of allowing the warm water for washing rice and the rice to move relatively, the function of washing rice can be realized in a mode of mechanically stirring the warm water for washing rice and the rice, rotating the rice washing cavity in a reciprocating mode, inflating and bubbling the water below the liquid level of the warm water for washing rice through an air pump, introducing steam into the water below the liquid level of the warm water for washing rice through a steam generator to form bubbles and the like.

And step S4, controlling the drainage unit to work after the rice washing is finished, so as to drain the rice washing water.

Specifically, when the drainage unit is controlled to operate, the rice washing water in the rice washing cavity can be drained to the wastewater container through the drainage pump, so that the rice washing water and dust and impurities in the rice washing water are drained out of the rice washing cavity.

In some embodiments of the present invention, the cooking appliance further includes a second heating unit for heating the cooking water to inject steam into the rice washing chamber, wherein the rice washing is performed according to the rice washing warm water, including: the second heating unit and the water inlet unit are controlled to wash rice by injecting steam into the rice-washing warm water.
