4A and 4B are flowcharts illustrating signal flow of a multi-functional electric stove according to an embodiment of the present invention.

First, when the user operates the key input unit 32 to select the automatic adjustment mode (first step: ST-1) and the fan mode (second step: ST-2), the cooking temperature may be set. When the user sets the cooking temperature (third step ST-3), temperature detection is started from the temperature sensing unit 8 (fourth step ST-4).

The temperature of the vessel detected by the temperature sensing unit 8 is continuously applied to the control unit 54. At this time, when the cooking is completed, the temperature of the vessel is increased, so that the control unit 54 has reached the cooking completion temperature. In order to determine whether or not, the present temperature of the vessel is compared with the preset temperature (step 5: ST-5).

When the current temperature of the container is equal to the preset temperature, the controller 54 determines that cooking is completed and stops heating (sixth step: ST-6).

The heating mode is a manual mode. When the user selects the heating mode (step 7: ST-7) and sets the maximum temperature during heating (step 8: ST-8), the controller 54 controls the temperature. The control unit 38 generates a control signal to detect whether the user reaches the preset maximum temperature while heating to the preset maximum temperature (step 9: ST-9).

When the set temperature is reached, the control is performed to maintain the set maximum temperature (step 10: ST-10).

At this time, when the user performs a heating stop key input through the key input unit 32 (ST-11: ST-11), the controller 54 generates a control signal to the switching unit 36 to supply power. Stop (Step 12: ST-12).

If the user selects the cooking mode by operating the key input unit 32 (step 20: ST-20), the controller 54 heats the hot plate to the cooking set temperature (step 21: ST-). 21), the temperature of the vessel is continuously detected through the temperature sensing unit 8 (step 22: ST-22).

At this time, when the current temperature applied from the temperature sensing unit 8 reaches the cooking completion temperature (step 23: ST-23), the control unit 54 is switched to the warming mode and the temperature of the container at the preset warming temperature. To be maintained (Step 24: ST-24).

On the other hand, the multi-functional electric furnace and the temperature control method according to an embodiment of the present invention is not limited only to the above-described embodiment is possible various modifications within the scope not departing from the technical gist.

As described above, the multi-functional electric stove according to the present invention and its temperature control method can control the temperature by maintaining the optimum cooking temperature and cooking temperature by adjusting the temperature according to the set temperature during cooking and cooking. When it is completed, it automatically stops heating, and when cooking is completed, it automatically switches to the warming mode, so it is safe and very convenient to use.

In addition, the multi-functional electric stove and the temperature control method according to the present invention has a more precise temperature (1 ° C unit) is possible because it is possible to cook food more delicately than the conventional stove.
