5, and the condensed water is passed through the drain hose 40 from the drain port 38 provided in the steam guide 36.
The water passes through and is stored in the condensation water receiver 39. In addition, the steam that has not condensed in the steam cooling chamber 35 is discharged into the wind tunnel 33 from the steam drain port 37 provided in front of the upper surface of the steam cooling chamber 35, and is mixed with the air blown by the blower 34, resulting in humidity. The steam is discharged from the rice cooker main body 20 from the steam outlet 23 in a state where the steam is lowered. When the rice cooking is completed, the steam coming out from the rice cooker main body 27 disappears, and the steam cooling chamber 35
The wall temperature of the thermal reed switch 41 begins to decrease, and the temperature of the thermal reed switch 41 also begins to decrease. When the temperature of the thermal reed switch 41 becomes lower than the operating temperature of the thermal reed switch 41, the thermal reed switch 41 is turned off, the current of the air blower 34 is turned off, and the air blower 34 stops blowing air.
