Electronic temperature control cooking device and control method thereof

The invention relates to a cooking device and a control method thereof, and in particular to an electronic temperature control cooking device and a control method thereof.

In general, an electronic pan usually has an outer pot, an inner pot, and a temperature controller and heater mounted on the bottom of the outer pot. When the electronic pot is in the process of cooking, the heater continuously heats the water in the outer pot, whereby the food in the inner pot can be heated by water. During cooking in the electronic pan, the water in the inner and outer pots will continue to boil (ie, maintain at 100 ° C) until the water in the outer pot has completely evaporated. At this point, the temperature controller will stop the heater operation or adjust the heater to a holding state below 100 °C.

Since the general electronic pan cannot control the water temperature of the outer pan during the cooking process, the water temperature inside the electronic pan will be maintained at a high temperature of 100 ° C during the cooking process. That is to say, the general electronic pan is cooked at a high temperature throughout the cooking process. However, some ingredients are not suitable for cooking at a high temperature of 100 °C. Or, some ingredients must be used for a long time at temperatures below 100 °C. Cooking can avoid destroying the nutrients of the ingredients or affecting the taste of the ingredients. In addition, some ingredients can show the true taste of the ingredients under the long-term low-temperature cooking, and can also reduce the harmful substances produced by high-temperature cooking. However, the above cooking conditions are not achievable in a general electronic pan.

Please refer to FIG. 1 and FIG. 2 below. FIG. 1 is a block diagram of an electronic temperature-controlled cooking device 100 according to an embodiment of the invention. FIG. 2 is a schematic diagram of the electronic temperature control cooking device 100 used in conjunction with the electronic pot 200. The electronic temperature-controlled cooking device 100 includes a temperature sensor 120 and a controller 140. The temperature sensor 120 may be disposed inside the electronic pot 200 to sense the water temperature inside the electronic pot 200, and accordingly generate the temperature sensing value TS. In detail, as shown in FIG. 2, the electronic pot 200 may have an outer pot 220 and an inner pot 240, but is not limited thereto. Therefore, the user can place the temperature sensor 120 in the water of the inner pot 240 of the electronic pot 200 (as shown in FIG. 2) to sense the water temperature of the inner pot 240, or the user can also set the temperature. The sensor 120 is placed in the water of the outer pot 220 of the electronic pot 200 to sense the water temperature of the outer pot 220, depending on the actual situation. It depends on the cooking needs.

The controller 140 is configured to set a preset temperature value DT and can be used to control the electronic pot 200 internal water temperature. In detail, the controller 140 may include the control chip 142 and the communication module 144, but is not limited thereto. The control wafer 142 is coupled to the temperature sensor 120 to receive the temperature sensing value TS. The control wafer 142 compares the temperature sensed value TS with a preset temperature value DT and accordingly generates a control signal CS. Communication module 144 is coupled to control wafer 142. The control chip 142 can transmit the control signal CS to the electronic pot 200 through the communication module 144, so that the electronic pot 200 maintains the internal water temperature thereof at the preset temperature value DT according to the control signal CS. In addition, after the electronic pot 200 completes the cooking process, the control wafer 142 can also pass through the communication module 144 to receive the state ST of the electronic pot 200 or the cooking result CR.

Further, in the embodiment, the electronic pot 200 further includes control Circuit 210, heater 230, and communication unit 250. The control circuit 210 is used as an operation core of the electronic pot 200 to control the overall operation of the electronic pot 200. The communication unit 250 is configured to receive the control signal CS from the electronic temperature-controlled cooking device 100 or to transmit the state ST of the electronic pan 200 or the cooking result CR to the electronic temperature-controlled cooking device 100. Therefore, the control circuit 210 of the electronic pot 200 can control the overall operation of the electronic pot 200 according to the received control signal CS (for example, to activate or deactivate the heater 230, but is not limited thereto) to water the inside of the electronic pot 200. The temperature is maintained at the preset temperature value DT.

In general, when the user wants to use the electronic pot 200 at a lower temperature (less than the boiling point of water 100 ° C, such as 70 ° C, but not limited to this) and a longer time to When the food is cooked, the user only needs to place the temperature sensor 120 in the water of the outer pot 220 or the inner pot 240 of the electronic pot 200 to sense the water temperature, and set the required temperature through the controller 140 (ie, The preset temperature value DT, for example, 70 ° C). In this way, during the entire cooking process, when the control wafer 142 determines that the temperature sensing value TS is greater than the preset temperature value DT (eg, 70 ° C), the control chip 142 can generate a corresponding control signal CS and pass through the communication module. 144 transmits control signal CS to electronic pot 200. The control circuit 210 of the electronic pot 200 receives the control signal CS through the communication unit 250, and controls the heater 230 to stop heating according to the received control signal CS. At this time, the temperature of the water inside the electronic pot 200 will gradually decrease with time.

In contrast, when the control wafer 142 determines that the temperature sensing value TS is less than the preset temperature value DT (for example, 70 ° C), the control chip 142 can generate a corresponding control signal CS, and the communication module 144 transmits the control signal CS to the communication module 144. Electronic pot 200. The control circuit 210 of the electronic pot 200 can control the heater 230 to start heating according to the received control signal CS. At this time, the heater 230 in the electronic pot 200 starts to operate to warm the water inside the electronic pot 200, so that the temperature sensing value TS rises. Such a repeated cycle action maintains the temperature sensing value TS at a preset temperature value DT (for example, 70 ° C). That is, the water temperature inside the electronic pot 200 will be maintained at a preset temperature value DT (for example, 70 ° C).

In addition, the user can visualize the cooking needs throughout the cooking process. The required temperature (ie, the preset temperature value DT) is reset at any time through the controller 140. When the preset temperature value DT is changed (for example, from 70 ° C to 50 ° C, but is not limited thereto), the control wafer 142 may be based on the reset preset temperature value DT (ie, 50 ° C) The control signal CS is generated, and the control unit CS is instructed to turn on or off the heater 230 to maintain the water temperature inside the electronic pot 200 at the reset preset temperature value DT (ie, 50 ° C).

On the other hand, the controller 140 can also be used to set a predetermined time PT, wherein the predetermined time PT represents the length of time the electronic pan 200 performs cooking. When the control wafer 142 transmits the control signal CS to instruct the electronic pot 200 to start cooking, the control circuit 210 can activate the heater 230 based on the received control signal CS. At this time, the control wafer 142 will start timing to obtain the cooking time CT of the electronic pot 200. Control wafer 142 can compare cooking time CT to predetermined time PT. When the control wafer 142 determines that the cooking time CT is equal to the predetermined time PT, it indicates that the electronic pot 200 has completed the cooking program set by the user, and therefore the control wafer 142 can transmit the control signal CS to instruct the electronic pot 200 to stop cooking. At this time, the control circuit 210 can turn off the heater 230 according to the received control signal CS, and transmit the state ST or the cooking result CR of the electronic pot 200 to the electronic temperature control cooking device 100 through the communication unit 250.
