  • First, the example may begin by registering dedicated cooking utensils the user wants to use on the electric stove. Registration method is as follow: when the dedicated cooking utensil is placed on the stove, the stove is synchronized with the cooking utensil, such that information such as model name, container floor area, capacity and weight of the cooking utensil is registered into the cooking solution via RFID, NFC, Zigbee and Bluetooth. In this connection, the cooking utensil may have a transmitter or RFID transmitter to transmit the information thereof to the stove.
  • FIG. 7 is a flow chart for illustrating a first example of an operation of the intelligent electric stove in accordance with the present disclosure. Referring to FIG. 7, when the water filled pot is placed on one heating region of the electric stove 100, the electric stove is synchronized with the pot to prepare for the operation. When the start button is pressed, the firepower will start heating and adjust the level of the heating power based on the sensed floor area of the pot and the sensed amount of water (S1, S2).
  • At this time, the stove estimates the cooking time by measuring the amount of water contained in the pot through the weight sensor 161.
  • When the internal temperature of the pot reaches 100° C, the sensor in the pot may detects this and sends it to the electric stove (S3).
  • When the electric stove receives the detection, the electric stove adjusts the level of the fire power to zero and notifies the completion of the cooking process through a beep or a mobile device application and finishes the cooking process (S4, S5, S6)
  • When the cooking time that is expected in this process exceeds a predetermined time, the stove adjusts the firepower to 0 level and sends warning alarm.
  • The above example can be applied to any cooking utensil that is used to boil water in the registered cooking utensil rather than limited to the pot. The above operation of the first example may be programed in the cooking solution stored in the memory in the main control unit 110.
  • Second example (control function based on recipe)
  • FIG. 8 is a flow chart for illustrating a second example of an operation of the intelligent electric stove in accordance with the present disclosure. FIG. 8 shows an example of registering and executing a recipe such as ramen cooking in a cooking solution.
  • Referring to FIG. 8, when the water filled pot is placed on one heating region of the electric stove 100, the electric stove is synchronized with the pot to prepare for the operation. When the start button is pressed, the firepower will start heating and adjust the level of the heating power based on the sensed floor area of the pot and the sensed amount of water (S1, S2).
  • At this time, the stove estimates the cooking time by measuring the amount of water contained in the pot through the weight sensor 161.
  • When the water starts to boil, the sensed information in the vessel is sent to the electric stove and informs the user that the water has boiled and noodle and seasoning agents should be put in (S3, S4). At this time, sound can be informed directly. Alternatively, the display of the electric stove may display the image of the food to be injected into the pot. Alternatively, the mobile device can may display the image of the food to be injected into the pot. This procedure may be set into the cooking solution.
  • Thereafter, in operation S6, it is recognized by the timer whether the indicated proper cooking time on the ramen package, for example, 4 minutes and 30 seconds has lapsed. If so, the electric stove adjusts the heating power level to 0 level (S7). Then, the stove informs the user of the cooking completion of the ramen (S8). In this way, the cooking process may end (S9).
  • In this example, the recipe of simple ramen cooking is given as an example. However, in the case of complicated cooking process, time for food injection into the pot and/or the thermal power control may be pre-set in the cooking solution.
  • Third example (programmed control for pressurized cooking container)
  • FIG. 9 is a flow chart for illustrating a third example of an operation of the intelligent electric stove in accordance with the present disclosure. FIG. 9 describes the process of cooking rice using pressurized cooking container merely by selecting the menu preprogrammed in the cooking solution until the completion of rice cooking.
  • A dedicated pressurized cooking container used here has a solenoid valve which is operated by an electrical signal in addition to the temperature sensor.
  • First, when the water and raw rice is injected into the pressurized cooking container registered onto the present electric stove and is placed on the heating region of the stove, the user may press the rice cooking button in the user interface corresponding to the menu of the cooking solution. In this embodiment, the heating power level may be adjusted automatically according to the timing schedule preset into the cooking solution.
  • The operation A in the figure is to maintain the proper cooking condition of 1.2 atmospheric pressure and 122 °C in the cooking process using the pressurized cooking container. The operation A may be incorporated at least one time during the entire cooking process.
  • In operation (S7), the firepower level of the stove is adjusted to 0 and the zero level lasts for a predetermined time while the cooking completion is not notified to the user. This is for complete softening of the raw rice by uniform transfer of the heat to the inner portion of the rice. Thereafter, in order to open the lid of the container safely after the lapse of the cooking time, the user may remove the operating pressure on the solenoid valve to relieve pressure.
  • The heating powers and cooking times presented here are for explanation purposes only. Thus, the present disclosure is not limited thereto.
  • Combining these series of cooking factors, various kinds of foods for example, rice, potato, beef, chicken, etc. can be cooked using the combination of the present stove and the pressurized cooking utensil.
  • Further, regarding the operation of the stove hood 300, which is missing from the examples, when the cooking temperature of the cooking utensil 200 during cooking by electric stove 200 react a predetermined temperature, the electric stove confirms the operation status of the stove hood by inter-communication between the hood and the stove. When the hood is not in operation, the stove sends an operation signal so that the stove hood 300 operates.
  • At a predetermined time after the cooking process of the electric stove is completed, the operation of the stove hood 300 is checked again. When the stove hood 300 is still operating, the stop signal is transmitted to stop the operation.
  • Further, when the stove hood is continuously operated for a certain period of time when the electric stove is not in operation, the user is notified of the stove hood abnormality to the user.
  • Industrial application
  • In addition, although the above-described examples only describe general containers such as pots, general cooking utensils and pressurized cooking containers, the present disclosure is not limited thereto. For example, the present stove may be combined with the steamer container or boiler container, etc.
