[0047] In one embodiment, for the control method of the cooking appliance provided in the present application, the application environment may simultaneously involve the cooking appliance 102 and an external control device 104, such as Figure 1As shown in the figure. Among them, the cooking appliance 102 includes a gas valve, a pot support, and a controller. The pot support can support cooking utensils, and an electrode plate is provided on the pot support. The controller in the cooking appliance 102 can communicate with an external control device 104 through a network. Specifically, a user can send a start working instruction to the controller of the cooking appliance 102 through the external control device 104. After receiving the start working instruction, the controller of the cooking appliance 102 controls the opening of the gas valve so that the cooking appliance 102 starts to work. During the working process of the cooking appliance 102, the controller continuously detects changes in the cooking parameters of the food in the cooking utensil placed on the pot support and transmits them to the external control device 104 in real time. When the external control device 104 determines that the changes in the cooking parameters of the food in the cooking utensil meet the flame adjustment conditions, it outputs an adjustment instruction to the controller. The controller receives the adjustment instruction sent by the external control device 104 and controls the adjustment of the energizing current of the electrode plate to adjust the flame shape on the cooking appliance 102.

[0048] In one embodiment, the control method of the cooking appliance provided in this application, the application environment only involves the cooking appliance 102. Among them, the cooking appliance 102 includes a gas valve, a pot support, and a controller. The pot support can support cooking utensils, and an electrode plate is provided on the pot support. The controller can control the cooking appliance 102. Specifically, a user can directly open the gas valve. When the controller detects that the gas valve is opened, it determines that the cooking appliance 102 starts to work. During the working process of the cooking appliance 102, the controller continuously detects changes in the cooking parameters of the food in the cooking utensil placed on the pot support, and when it detects that the changes in the cooking parameters of the food in the cooking utensil meet the flame adjustment conditions, it adjusts the energizing current of the electrode plate to adjust the flame shape on the cooking appliance 102.

[0049] Among them, the cooking appliance 102 can be but is not limited to various gas stoves, artificial gas stoves, liquefied petroleum gas stoves, etc. The controller in the cooking appliance 102 can be an electronic device, including but not limited to a control chip and a control circuit board, etc. The external control device 104 can be a terminal or a server. The terminal can be a personal computer, a laptop, a smart phone, a tablet computer, and a portable wearable device. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0050] In one embodiment, a cooking appliance is provided, which includes a gas valve, a pot support, and a controller. The controller is disposed inside the cooking appliance and can be specifically integrated in the pulse igniter of the cooking appliance. The controller can be communicatively connected to an external control device and controls the cooking appliance. A user can send the food attributes and cooking methods corresponding to various foods to be cooked to the controller through the external control device, so that the controller controls or adjusts the cooking appliance. The cooking methods include high-fire stir-frying, low-fire simmering, etc., and the food attributes include the specific heat capacity, water content, calories, etc. of the food. The specific heat capacity (Cp) of the food refers to the amount of heat required for a unit mass of the food to increase its temperature by one degree, which is related to the water content, components, and temperature of the food. The greater the specific heat capacity of the food, the longer the cooling time. Moreover, different foods and different cooking methods have different cooking times, nutrient losses, cooking oil consumption, etc. during cooking. Therefore, different foods require different flame sizes and flame shapes during cooking, and the controller needs to continuously adjust during the cooking process to make the flame shape and size adapt to the food to be cooked.

[0051] The gas valve is a control component for delivering gas to the cooking appliance and has functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief, and includes globe valves, butterfly valves, ball valves, gate valves, etc. When the cooking appliance is a gas stove, the gas valve can be the valve between the cooking appliance and the natural gas pipeline. When the gas valve is opened, natural gas can enter the cooking appliance through the gas valve, and then the pulse igniter of the cooking appliance can ignite, and a flame is generated on the cooking appliance, that is, the cooking appliance starts to work. The gas valve of the cooking appliance can be opened by the user. For example, the user twists it in a clockwise or counterclockwise direction at a preset angle to open the gas valve, or it can be controlled to open by the controller. For example, the controller outputs an opening instruction to the gas valve, and the gas valve opens according to the opening instruction. Specifically, the degree of opening of the gas valve is called the valve opening. The greater the valve opening of the gas valve, the more natural gas enters the cooking appliance, and the larger the flame size of the cooking appliance generated accordingly. Therefore, the controller or the user can adjust the flame size of the cooking appliance by adjusting the valve opening of the gas valve.

[0052] In one embodiment, the pot support is mainly used to support the cookware and is mainly made of stainless steel, cast iron, and copper forging, such as Figure 2The figure shows a schematic diagram of the pot support of the cooking appliance. Among them, the pot support includes an upper half 110, a support frame 120, and a lower half 130. The support frame 120 is arranged between the upper half 110 and the lower half 130, and the support columns of the support frame 120 are evenly distributed. The support frame 120 mainly plays a supporting role. When the user uses the cooking appliance for cooking, the pot can be placed on the pot support, and at this time, the pot contacts the upper half 110 of the pot support. Among them, the pot can be a frying pan, a wok, etc. The lower surface of the pot can be a flat surface or a convex surface. The material, shape, and use of the pot are not limited here.

[0053] Among them, the sizes and shapes of the upper half 110 and the lower half 130 of the pot support can be the same. The shape can be circular, oval, square, or polygonal, etc., as long as the pot can be stably placed on the pot support. For example, both the upper half 110 and the lower half 130 of the pot support are circular and of the same size, and the pot support is overall cylindrical, and the front view of the pot support is square. In addition, the sizes and shapes of the upper half 110 and the lower half 130 of the pot support can also be different, and the size of the lower half 130 of the pot support is larger than the size of the upper half 110 of the pot support to keep the pot support stable and enable the pot to be stably placed on the pot support. For example, the upper half 110 of the pot support is circular, the lower half 130 of the pot support is square, and the size of the square is larger than the size of the circular, and the front view of the pot support is trapezoidal.

[0054] Among them, at a position on the upper half 110 of the pot support close to the pot, a conductive electrode plate 10 is provided. The conductive electrode plate 10 is a current collector that can conduct electricity, and any conductive material can be made into the conductive electrode plate 10. For example, the conductive electrode plate 10 made of various metals, semiconductors, metal oxides, etc. The conductive electrode plate 10 can be one of a sheet shape, a flat plate, a spherical shape, and an irregular shape.

[0055] In one embodiment, in order to improve the safety of the user using the cooking appliance, the conductive electrode plate 10 includes more than two. The conductive electrode plates 10 are evenly arranged on the upper half 110 of the pot support. Every two conductive electrode plates 10 are symmetrically arranged, and an insulating material 20 is filled between every two conductive electrode plates 10 to prevent the conductive electrode plates 10 from short-circuiting. Since the flame temperature of the cooking appliance is relatively high, the insulating material 20 can be selected from high-temperature resistant insulating and heat-insulating materials, such as polytetrafluoroethylene, polyimide, etc., and ceramic materials can also be selected.

[0056] In one embodiment, as Figure 3The figure shows a schematic circuit connection diagram of the pot support of the cooker. Every two electrode plates 10 symmetrically arranged along the horizontal coordinate axes are connected to a low-frequency AC power supply 30, that is, the energizing current of the electrode plates 10 is low-frequency alternating current. Among them, the low-frequency AC power supply 30 can be an external independent power supply or can also be integrated in the pulse igniter of the cooker to supply low-frequency alternating current to the electrode plates 10. Specifically, the energizing current of the electrode plates 10 can stretch the flame to change the flame shape. The greater the energizing current of the electrode plates 10, the greater the degree of stretching of the flame and the greater the degree of change in the flame shape of the cooker. Therefore, the flame shape of the cooker can be adjusted by adjusting the energizing current of the electrode plates 10. For example, if the controller needs to adjust the flame shape to a wider flame shape, it can adjust the energizing current of the two electrode plates 10 symmetrically arranged along the horizontal coordinate axes to a larger energizing current to widen the flame shape.

[0057] In one embodiment, since the flame size is related to the valve opening of the gas valve, the flame shape is related to the energizing current of the electrode plates 10, and the required flame size and flame shape during cooking are related to the food properties and cooking methods of the food itself, it is necessary to pre-determine the relationship between the flame shape and size and the energizing current and valve opening according to the food properties and cooking methods of the food and store this relationship in the storage space of the controller so that the controller can subsequently adjust the flame shape and size according to the food in the pot.

[0058] In one embodiment, an infrared sensor is further provided on the pot support. During the operation of the cooker, the temperature of the food in the pot will change, and the infrared sensor is used to detect the temperature of the pot. Among them, a high-temperature resistant infrared sensor needs to be selected for the infrared sensor to improve the temperature detection efficiency. The infrared sensor can be arranged at a position close to the upper half 110 of the pot support. In addition, it can also be arranged at a position close to the lower half 130 of the pot support as long as the temperature of the pot can be detected. The infrared sensor includes at least one. When there are two or more infrared sensors, in order to improve the accuracy of temperature detection, the infrared sensors can be evenly distributed on the pot support. Specifically, the infrared sensor is communicatively connected to the controller and can transmit the detected temperature of the pot to the controller. In addition, the infrared sensor can also detect the shape and size of the pot. The infrared sensor can also be replaced by a high-temperature resistant temperature sensor, such as a thermocouple sensor, etc.

[0059] In one embodiment, as Figure 4The following is an overall schematic diagram of the cooking appliance. The cooking appliance further includes a liquid storage tray 40. The pot support is placed on the liquid storage tray 40. The liquid storage tray 40 is used to support the pot support so that the pot support can be stably placed. Among them, the liquid storage tray 40 is provided with a weight sensor. During the operation of the cooking appliance, the weight of the food in the pot will change, and the weight sensor is used to detect the weight of the pot. The weight sensor can be set in the liquid storage tray 40, at a position close to the lower half 130 of the pot support. In addition, it can also be set at a position far from the lower half 130 of the pot support, as long as it can detect the weight of the pot. The weight sensor includes at least one. When there are two or more weight sensors, in order to improve the accuracy of weight detection, the weight sensors can be evenly distributed on the liquid storage tray 40 and evenly distributed around the pot support. Specifically, the weight sensor is communicatively connected to the controller and can transmit the detected weight of the pot to the controller. Similarly to the infrared sensor, a high-temperature-resistant weight sensor also needs to be selected for the weight sensor to improve the weight detection efficiency.

[0060] In one embodiment, when the infrared sensor transmits the temperature to the controller, the detection time corresponding to the temperature is transmitted to the controller at the same time. Similarly, when the weight sensor transmits the weight to the controller, the detection time corresponding to the weight is transmitted to the controller at the same time, so that the controller can calculate the temperature change rate and the weight change rate to determine the cooking parameters of the food in the pot.

[0061] In one embodiment, when the cooking appliance starts to work, the controller will control the opening of the gas valve and control the electrode plate 10 to be energized according to the preset initial flame shape and initial flame size, as well as the relationship between the flame shape and size and the energizing current and valve opening, so that the cooking appliance cooks the food in the pot with the initial flame shape and initial flame size. Among them, the initial flame shape and initial flame size can be determined according to the shape of the pot. Specifically, when the user places the pot on the pot support, the infrared sensor detects the shape and size of the pot and transmits them to the controller. The controller determines the preset initial flame shape and initial flame size according to the shape and size of the pot.

[0062] In one embodiment, since the initial flame shape and initial flame size are related to the shape and size of the pot, it is necessary to pre-determine the relationship between the initial flame shape and size and the shape and size of the pot according to the shape and size of the pot, and store this relationship in the storage space of the controller so that the controller can determine the initial flame shape and initial flame size. For example, when the pot is a flat pan, the bottom surface of the pot is flat and the heat is relatively evenly distributed. At this time, the initial flame shape can be wider and the initial flame size can be smaller.

[0063] In one embodiment, during the operation of the cooking appliance, the controller continuously receives the temperature of the cookware detected by the infrared sensor and the weight of the cookware detected by the weight sensor to determine the changes in the cooking parameters of the food in the cookware. Among them, the cooking parameters include the temperature change rate and the weight change rate. When it is detected that the changes in the cooking parameters of the food in the cookware meet the flame adjustment condition, the energizing current of the electrode plate 10 is adjusted according to the stored relationship between the flame shape and size and the energizing current and valve opening degree, so as to adjust the flame shape on the cooking appliance.

[0064] In one embodiment, as Figure 5 shown, a control method for a cooking appliance is provided. Taking the controller in the cooking appliance 102 in Figure 1 as an example for illustration, it includes:

[0065] Step S502, during the operation of the cooking appliance, detect the changes in the cooking parameters of the food in the cookware placed on the pot support.

[0066] In one embodiment, the cooking appliance includes a gas valve, which can be opened by the user or controlled by the controller. Among them, when the gas valve is opened by the user, the controller determines that the cooking appliance starts to work when detecting the opening of the gas valve. When the gas valve is controlled by the controller to open, the controller receives the start work instruction sent by the user through the external control device, and the controller controls the opening of the gas valve according to the start work instruction to make the cooking appliance start to work.

[0067] In one embodiment, the cooking appliance includes a pot support, and an electrode plate is arranged on the pot support. Among them, the electrode plate is connected to a low-frequency AC power supply, and the energizing current of the electrode plate is low-frequency alternating current to ensure the safe use of the cooking appliance. The user can place the cookware on the pot support. The controller first controls the cooking appliance to cook the food in the cookware with a preset flame size and shape, and then gradually adjusts the flame shape and size. The preset flame size and shape are determined as the initial flame size and initial flame shape. Among them, the flame size is controlled according to the valve opening degree of the gas valve, and the flame shape is controlled according to the energizing current of the electrode plate. Since the food attributes and cooking methods corresponding to the food to be cooked are different, the required flame shapes and sizes during cooking are also different. Therefore, according to the food attributes and cooking methods of the food, the relationship between the flame shape and size and the energizing current and valve opening degree is determined in advance and stored in the storage space of the controller, so that the controller can gradually adjust the flame shape and size later. Among them, the food attributes include the specific heat capacity, water content, heat, etc. of the food.

[0068] Specifically, when the cooking appliance starts to work, based on the preset initial flame shape and initial flame size, as well as the relationships between the flame shape and size and the energizing current and valve opening degree, the controller outputs a first opening degree adjustment instruction to the gas valve. The first opening degree adjustment instruction carries first opening degree information and outputs a first current adjustment instruction to the pilot electrode plate. The first current adjustment instruction carries first current information. At this time, the valve opening degree of the gas valve is the first opening degree, and the energizing current of the pilot electrode plate is the first current. At this time, the flame size and flame shape on the cooking appliance are the initial flame size and initial flame shape.

[0069] In one embodiment, the cooking appliance further includes a liquid receiving tray, and the pot support is placed on the liquid receiving tray. The pot support is provided with an infrared sensor, and there is at least one infrared sensor. The infrared sensor is used to detect the temperature of the cookware and transmit the temperature to the controller. The liquid receiving tray is provided with a weight sensor, and there is at least one weight sensor. The weight sensor is used to detect the weight of the cookware and transmit the weight to the controller. During the working process of the cooking appliance, the temperature and weight of the food in the cookware are constantly changing. Therefore, the controller can adjust the flame shape and size according to the temperature and weight of the food in the cookware. Among them, when the infrared sensor detects the temperature of the cookware and the weight sensor detects the weight of the cookware, both adopt a periodic detection method, and their detection periods can be the same or different. When the infrared sensor transmits the temperature to the controller, the detection time corresponding to the temperature is transmitted to the controller together. Similarly, when the weight sensor transmits the weight to the controller, the detection time corresponding to the weight is transmitted to the controller together, so that the controller can calculate the temperature change rate and weight change rate.

[0070] Specifically, the infrared sensor detects the temperature of the cookware and transmits it to the controller. The controller determines the temperature change rate according to the detected temperature. The weight sensor detects the weight of the cookware and transmits it to the controller. The controller determines the weight change rate according to the detected weight. The cooking parameters include the temperature change rate and the weight change rate. The controller fits and determines the target flame shape and target flame size corresponding to the temperature change rate and the weight change rate. When the controller determines that the error between the target flame shape and size and the initial flame shape and size meets the flame adjustment condition, it adjusts the energizing current of the pilot electrode plate to adjust the flame shape on the cooking appliance, and can also adjust the valve opening degree of the gas valve to adjust the flame size on the cooking appliance.

[0071] Step S504, when it is detected that the change in the cooking parameters of the food in the cookware meets the flame adjustment condition, adjust the energizing current of the pilot electrode plate to adjust the flame shape on the cooking appliance.

[0072] In one embodiment, the controller can perform fitting based on the temperature change rate and the weight change rate to determine the required flame size and flame shape corresponding to the food in the cookware at this time, and the flame size and flame shape obtained by fitting are respectively referred to as the target flame size and the target flame shape. Specifically, the controller fits and determines the target flame shape and the target flame size corresponding to the temperature change rate and the weight change rate.

[0073] In one embodiment, after the controller obtains the target flame size and the target flame shape by fitting, if it is determined that the flame adjustment condition is satisfied at this time, the energizing current of the electrode plate needs to be adjusted to adjust the flame shape on the cooker. Specifically, the controller calculates the error between the target flame shape and the target flame size and the initial flame shape and the initial flame size. If the error between the target flame shape and the target flame size and the initial flame shape and the initial flame size is greater than the preset error, it is determined that the flame adjustment condition is satisfied. Among them, the preset error is determined based on a large number of experiments and can be set to 20%. The controller adjusts the energizing current of the electrode plate to adjust the flame shape on the cooker.

[0074] In one embodiment, when the controller determines that the flame adjustment condition is satisfied, adjusting the energizing current of the electrode plate to adjust the flame shape on the cooker includes: the controller determines the second current information corresponding to the current to be adjusted of the electrode plate according to the error between the target flame shape and the target flame size and the initial flame shape and the initial flame size, and the relationship between the flame shape and the flame size and the energizing current and the valve opening, and outputs a second current adjustment instruction to the electrode plate, and the second current adjustment instruction carries the second current information. At this time, the energizing current of the electrode plate is the second current, and the flame shape on the cooker is adjusted from the initial flame shape to the target flame shape.

[0075] In one embodiment, since during the cooking process of the food in the cookware, only the flame size can be adjusted, or only the flame shape can be adjusted, in order to improve the adjustment efficiency of the flame size and the flame shape, the above-mentioned preset error can be further subdivided. Specifically, the preset error is set as a preset error range, which can be set to less than 10%, 10% to 20%, and more than 20%. Among them, when the error calculated by the controller is less than 10%, it is determined that the initial flame shape and the initial flame size are suitable for the food in the cookware and no adjustment is required. When the error calculated by the controller is between 10% and 20%, it is determined that the initial flame size is suitable for the food in the cookware, and only the flame shape needs to be adjusted. When the error calculated by the controller is more than 20%, it is determined that both the initial flame shape and the initial flame size are not suitable for the food in the cookware, and both the flame shape and the flame size need to be adjusted.

[0076] In one embodiment, when the controller determines that the flame adjustment condition is met, it adjusts the energizing current of the electrode plate to adjust the flame shape on the cooking appliance. It further includes: The controller determines the second opening information corresponding to the opening of the gas valve to be adjusted according to the error between the target flame shape and size and the initial flame shape and size, as well as the relationship between the flame shape and size and the energizing current and valve opening, and outputs a second opening adjustment command to the gas valve. The second opening adjustment command carries the second opening information. At this time, the valve opening of the gas valve is the second opening, and the flame size on the cooking appliance is adjusted from the initial flame size to the target flame size.

[0077] In one embodiment, the controller can also be a controller with learning ability. During each operation of the cooking appliance, the controller stores the food attributes, cooking methods of the food in the corresponding cookware, as well as the corresponding flame shape, flame size, etc., so as to perform data processing more quickly subsequently.

[0078] In the control method of the above cooking appliance, the cooking appliance includes a gas valve, a pot support, and a controller. An electrode plate is provided on the pot support; the controller controls the opening of the gas valve to start the operation of the cooking appliance. During the operation of the cooking appliance, the controller detects changes in the cooking parameters of the food in the cookware placed on the pot support, and when it detects that the changes in the cooking parameters of the food in the cookware meet the flame adjustment condition, it adjusts the energizing current of the electrode plate to adjust the flame shape on the cooking appliance. By adopting the method of the above embodiment, by providing an electrode plate on the pot support, the adjustment of the flame shape on the cooking appliance can be realized, and by adjusting the energizing current of the electrode plate, the precise control of the flame shape can be realized. Adjusting the flame shape after detecting the cooking parameters of the food in the cookware can make the flame shape adapt to the food attributes and cooking methods of the food in the cookware, thereby improving the cooking effect.
