At this time, a large amount of carbohydrates are stored in the form of starch in grains such as rice, and excessive absorption of such carbohydrates may cause various cardiovascular problems including adult diseases such as obesity and diabetes.

Thus, to enable cooking with a low starch content for diet, etc., a solenoid valve is installed on the lower surface of the inner pot in which food is accommodated, the inner pot is filled with heating water to heat it, and then the solenoid valve is opened to supply the heated water. An electric cooker that separates starch as a method of discharging has been developed.

However, the conventional electric cooker requires a separate device such as an solenoid valve to discharge the heated water from which the starch is eluted to the outside of the inner pot, and a separate water tank for collecting the water discharged from the inner pot is required. There was a problem in that assembly was complicated and productivity was lowered.

Moreover, in the conventional electric cooker, as the water used to separate the starch flows in from the outside of the inner pot and is discharged to the water tank through the inner pot, the amount of water consumed during cooking increases as well as the overall cooking quality is low. There was a problem that the satisfaction of the consumer was lowered.

In addition, the maximum cooking water volume (b1) is the volume from the upper surface of the separating plate 20 to the level at which the cooking object r corresponding to the maximum cooking amount of the cooking region (b) can be completely immersed. it means.

Accordingly, when the inner pot 10 is heated, while the lower end of the siphon tube 25 is submerged in the heated water of the storage area c, the object to be cooked is completely immersed in the hot water w. The heating water (w) may be filled along the upper surface of the separating plate 20 and the upper portion of the separating plate packing 30 so that the heating water (w) may be filled.

At this time, as the upper opening of the inner pot 10 is covered by the inner lid 50b, it is possible to prevent the scattered and discharged heated water (w) or foreign substances from flowing into the cooking region (b). , A communication state between the cooking region b and the external atmosphere may be maintained through the communication hole 52 of the inner lid 50b.

In addition, the separating plate 20 covers the lower portion of the cooking area b and is disposed opposite to the storage area c. At this time, the lower surface of the separating plate 20 is in contact with steam heated by high temperature, and the upper surface of the separating plate 20 is in contact with the heated water w raised to the cooking region (b).

That is, the receiving space (a) is divided into the storage area (c) and the cooking area (b) through the separating plate 20, and the heat of the water vapor heated at high temperature in the storage area (c) is separated from the It may be transmitted to the heated water in the cooking region (b) through the entire area of the plate 20.
