[TECHNICAL FIELD OF THE INVENTION AND RELATED ART OF THE SAME]

The present invention relates to an electric pressure insulating cooker.

In particular, the present invention relates to a method of preventing the formation of lid water in an electric pressure heat-resistant rice cooker which can prevent the quality of rice from being lowered due to the occurrence of dripping phenomenon due to water being formed in the lid while the electric pressure warming rice cooker performs the warming function.

A general electric pressure heat-insulated rice cooker is composed of a key input unit constituted by keys for setting various operation environments of an electric pressure heat-insulated rice cooker having a cooking function and a heat retaining function, and a heater disposed at the bottom, the body and the lid of the electric pressure heat- A microprocessor for controlling the operation of the electric pressure heat-insulated rice cooker by a temperature value detected by a key input of the key input unit and a temperature sensor; A plurality of heaters installed under the control of the microprocessor to heat the inside of the electric pressure heat-insulated rice cooker, and a display unit for displaying the operation state of the electric pressure heat-insulated rice cooker.

1, the microprocessor determines whether various cooking modes are set by key input of a key input unit during a standby state (S101) after the operation power is turned on (S102) .

When the cooking mode is set, the cooking heater is operated and the heater for the lid and the heater for the lid are operated to execute the set cooking mode (S103). That is, the operation time and the operating temperature of the cooking heater, the heater for the lid, and the heater for the body are controlled according to each cooking mode to perform the cooking mode set.

When the operation of the cooking mode set as described above is terminated (S104), the cooking heater is cut off (S105), the operation power supplied to the heater for the lid and the heater for the lid is turned off (S105) It is determined whether the internal temperature of the pressure-insulated rice cooker is lower than a predetermined temperature (75 DEG C) (S107).

As a result, when the internal temperature of the electric pressure heat-insulating rice cooker is higher than a predetermined temperature (75 ° C), the above-mentioned operation is repeatedly performed. However, when the internal temperature of the electric pressure heat- The heater is operated (S108) to raise the internal temperature of the electric pressure heat-insulating rice cooker.

Therefore, since the internal temperature of the electric pressure heat-insulated rice cooker is maintained at a predetermined temperature (75 ° C), the rice stored therein can be kept warm.

[Technical Problem]

However, while the cooking function is completed and the heating function is switched, the operation power supplied to the heater installed on the floor and the body and the lid is shut off at the same time, but the temperature of the floor, the body and the lid changes. And thus the water was dropped on the rice and the quality of the rice was deteriorated.

Of course, even during the warming function of the electric pressure cooker, the electric power supplied to the bottom, the body and the lid heater is simultaneously shut off in order to raise the internal temperature of the electric pressure cooker. Therefore, the temperature of the floor, the body and the lid are changed differently. Water condensation phenomenon occurs and water has fallen on the rice, which has a drawback that the rice is whitened.
