detailed description

A heating device and a heating control method, including a separate heating container and a heating controller; a heating device, a temperature sensor, and a type identification element are arranged in the heating container, and the heating device, temperature sensor, and type identification element are connected to the heating controller through the corresponding connection port of the interface Connected; the heating controller receives signals from sensors and type identification elements in the heating container through the interface and outputs heating signals to control the heating device of the heating container through the interface; when heating, the heating controller is provided with cooking step control parameters and preset parameters, The cooking step control parameters include set temperature, heating power, standard water holding time and water coefficient, and the preset parameters include type identification parameters and standard water heating time corresponding to the type identification parameters; Group cooking steps, set corresponding cooking step control parameters for each cooking step, and the heating controller operates according to the control parameters of each heating step. The specific operation method is as follows:

a. Power on the heating controller.

b. The heating controller reads the type identification element data through the interface and corresponds to the type identification parameters to obtain the standard water volume heating time of the corresponding type of heating container. Since the heating speed of each heating container is different, such as aluminum and porcelain, it will directly affect the cooking process, so it is necessary to set the heating time of the standard water volume according to different heating containers, and because the actual cooking water is not According to the standard water volume, it may exceed the standard water volume or be less than the standard water volume, and the actual water volume is calculated through the standard water volume in step c so as to adjust the corresponding parameters of the subsequent cooking procedure. For example, the standard amount of water can be set to 1 liter, the time from normal temperature to boiling, etc. Of course, other methods can be used to set the heating time of the standard quantity, such as calculating the time used for heating a certain temperature range.

Then, the user sets different cooking steps and the cooking step control parameters in each cooking step. The cooking step control parameters are mainly used to control the heating controller in the cooking step. In actual use, the user sets the cooking steps and the cooking step control parameters. The parameters can also be written into the memory of the heating controller by setting the corresponding cooking steps and control parameters according to some common ingredients or cooking methods by the manufacturer, and the cooking steps and control parameters of the memory can be directly called when the user uses it. Parameters automatically control the heating controller to realize cooking, but if there are no prefabricated cooking steps and control parameters, users can set them according to actual needs.

c. The heating controller executes according to the first cooking step and outputs a heating signal to the heating device of the heating container according to the heating power, and records the actual heating time used by the temperature sensor in the cooking step to raise the temperature to the set temperature of the first cooking step, and The actual heating time is compared with the standard water heating time to calculate the actual water volume and water volume coefficient. According to the fact that the heating time is basically proportional to the amount of water, that is, the amount of water increases, and the heating time also increases according to the corresponding ratio. Therefore, the actual amount of water can be calculated by measuring the actual heating time in the first cooking step, so as to change the subsequent cooking steps. The corresponding parameters, such as heating power, water coefficient, etc., to meet the needs of actual cooking.

d. The heating controller enters the subsequent cooking step. The heating controller outputs a heating signal to the heating device of the heating container, and receives the temperature sensor data to compare with the set temperature in the cooking step. When the temperature detected by the temperature sensor reaches the control parameter When setting the temperature, the heating controller calculates the actual holding time according to the water volume coefficient and the standard water holding time, and outputs the heating signal to the heating device of the heating container according to the actual holding time and heating power. The temperature sensor monitors the temperature of the heating container in real time. When the set temperature of the cooking step is reached, the heat preservation is started and timed according to the actual heat preservation time. After completion, the next cooking step is entered.

e. Repeat the operation method d until the operation is completed.

The heating controller can be connected to various types of cooking utensils through the interface, such as soup pots, rice cookers, etc. Different types of cooking utensils can be identified by the type identification element so that the heating controller can be identified so that the appropriate heating degree can be selected for cooking; the heating controller can be used according to Set corresponding cooking steps for different ingredients or cooking methods, and control the heating power and heating time of the heating controller through the cooking step control parameters. After starting, the heating controller can automatically control the parameters according to the cooking steps and corresponding cooking steps. When in use, the user can set the cooking steps and cooking step control parameters according to the cooking needs to realize automatic cooking. At the same time, the manufacturer can also preset the cooking steps and cooking step control parameters required by some ingredients or cooking methods in the heating controller according to actual needs. , the user can directly choose to use.

In order to facilitate the heating controller to accurately identify the type of cookware, the type identification element can be realized by using various electronic devices, such as ID integrated circuits, etc., but considering the simplification of the control circuit, the present invention is preferably used as a resistance element, and different types of heating containers use Resistors of different resistance values serve as type identification elements. Generally speaking, the number of types of heating vessels is limited, usually within ten, so the resistance values of different types of cookware can be relatively different. or current, etc., and does not require high measurement accuracy.

Heat the cookware while cooking. Once a fault occurs, if the water in the cooker is completely evaporated, it will cause a fire if it continues to heat. Therefore, in addition to controlling the temperature of the heating part of the cooker, it is necessary to install temperature sensors on other parts of the cooker, such as the top and side of the cooker. The corresponding temperature sensors include normal position temperature sensors, such as the bottom of the cooker, and safety protection temperature sensors, such as the top and side walls of the cooker. Then the corresponding heating controller presets parameters to set the abnormal protection temperature, and the corresponding operation method has a protection step. When the temperature of the safety protection temperature sensor is higher than the abnormal protection temperature, the heating controller executes the protection step, and the cooking step is controlled in the protection step. The heating power of the parameter is set to zero, that is, the heating controller will not output any heating signal to the heating container to ensure safety.

As mentioned above, due to the corresponding relationship between the actual water volume and the standard water volume, the heating time, the actual water volume = the standard water volume * the actual heating time / the standard water volume heating time. Of course, when the actual water volume is different from the standard water volume, the corresponding holding time of the cooking step should also be adjusted, specifically: actual holding time = standard water holding time*((1-water volume coefficient/10)+(actual water volume/10)* (water volume factor/10)).
