Description

Electric cooker

The present invention relates to an electric cooker, and more particularly, to an electric cooker which improves productivity with a simple structure while reducing the starch content of the cooking object when cooking.

In general, an electric cooker means an electric rice cooker, an electric pressure cooker, etc. used for cooking food in a business or at home, and includes a main body provided with a heating unit and a lid covering the upper portion of the main body.

In addition, the inner pot is built in the main body, and when the washed rice is put into the inner pot, the inner pot is heated by the heating unit, and the cooking process may proceed.

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

Thus, the solenoid valve is mounted on the lower surface of the inner pot to accommodate food, and the heating is performed by filling the heating water inside the inner pot so as to enable the cooking of low starch content for the purpose of dieting and the like. An electric cooker that separates starch as a method of discharge has been developed.

However, the conventional electric cooker requires a separate device such as a solenoid valve for discharging the hot water eluted from the starch outside the inner pot, and requires a separate tank for collecting water discharged from the inner pot. There is a problem that assembly is complicated and productivity is lowered.

Moreover, the conventional electric cooker has a one-way flow in which water used for separating starch is introduced from outside the inner pot and discharged through the inner pot into the water tank increases the amount of water consumed in cooking and lowers the overall cooking quality. There was a problem that the customer's satisfaction is lowered.

On the other hand, the atmospheric pressure is maintained in the cooking zone b communicated with the atmosphere through the penetrating portion 50c of the lid 50, and the siphon tube communicated with the cooking zone b through the opening 26. Atmospheric pressure is also maintained inside 25.

When the vapor pressure of the water storage region c becomes higher than the atmospheric pressure, the heating water w of the water storage region c becomes a siphon tube due to the pressure difference between the water storage region c and the cooking region b. It may rise along 25) and be supplied to the cooking zone b.

In this case, the heating water of the reservoir region c may be elevated to the cooking zone b until the surface water level drops to a height corresponding to the lower end of the siphon tube 25. That is, when the water level of the reservoir region c decreases below the height of the lower end of the siphon tube 25, steam flows between the lower end of the siphon tube 25 and the surface of the water and thus the cooking region b and the reservoir region c. Since the pressure difference between) is removed, the heating water w raised to the cooking zone b is lowered to the water storage zone c again.

Accordingly, the heating water of the volume c1 corresponding to the lower portion from the lower end of the siphon tube 25 among the storage region c does not rise to the cooking region b, and the heating of the storage region c does not occur. Only the heating water accommodated in the upper side from the lower end of the siphon tube 25 in the water can be raised to the cooking zone (b), the length of the siphon tube 25 and the stepped portion (25) supported by the separation plate ( The position of 11) acts as the main variable when the heating water is elevated.

Here, the position of the step portion 11 is the volume c2 of the available reservoir region corresponding to the upper outer side from the lower edge of the siphon tube 25 of the reservoir region (c) is the volume of the siphon tube 25 Preferably, the sum is greater than the sum of the maximum water volume b1 of the cooking region b and the cooking region b.

In detail, the available reservoir region is located between the inner circumference of the inner pot 10 from the outer circumference of the siphon tube 25 among the lower surface of the separation plate 20 from a plane corresponding to the lower end of the siphon tube 25. It means the corresponding area.

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

In addition, the heated water lowered into the free space b2 may flow toward the opening 26 along the slope of the drain guide surface portion 22 and may be discharged to the water storage area c.

In addition, as the power supply and shut-off of the heating unit 40 is repeated by the controller 61 in a predetermined cycle, the heating water w is supplied to the cooking region b, and the heated water w is supplied. The process of draining the water to the reservoir region c is repeated, and the starch contained in the cooking object r can be efficiently separated while the cooking object r is cooked.

At this time, it is preferable that the bottom portion of the inner pot 10 is formed to be inclined downward as the outer region 19 of the central portion facing the siphon tube 25 is radially outward. Accordingly, the starch is collected in the portion where the high specific gravity heated water w is eluted, and the starch content in the heated water w supplied to the cooking zone b may be reduced during subsequent heating.

As such, the siphon tube 25 connecting the reservoir region c and the cooking region b is provided at one side of the separation plate 20 partitioning the receiving space a of the inner pot 10 up and down. Therefore, the heating water w flows to the cooking zone b and the storage zone c only by a change in the vapor pressure of the storage zone c through the heating unit 40, Starch can be separated efficiently.

Accordingly, it is possible to provide a compact product that is capable of cooking low starch content for diet, diet, and the like, but does not require a separate reservoir or valve device for discharging the heated water.

In addition, unlike the culinary cooking, the heating water (w) is raised so as to be in direct contact with the cooking object (r) in accordance with the difference in the steam pressure between the water storage area (c) and the cooking area (b) cooking object (r). It can be cooked with absorbing sufficient moisture to improve the cooking quality of the product.
