Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smart home, and in particular to an oven preheating method and an oven. BACKGROUND

[0002] The oven needs to be preheated before baking food, and the length of the preheating time and the stability of the preheating environment are important factors affecting the user's baking experience. The shorter the preheating time and the more stable the preheating environment, the better the user's baking experience and the higher the satisfaction. Conversely, the longer the preheating time and the less stable the preheating environment, the worse the user's baking experience, the greater the energy loss of the oven and the demand for preheating resources, and the lower the user's satisfaction.

[0003] At present, the oven generally drives a high-power heating pipe or a heating pipe corresponding to the baking mode to improve the internal temperature. However, the preheating method of driving the heating pipe corresponding to the baking mode is prone to the problem of too long preheating time, and the preheating method of driving the high-power heating pipe is prone to the problem that the internal temperature of the oven does not meet the food baking requirements (for example, the preheating temperature in the oven is not appropriate, the temperature of the heating pipe required for baking food is too low or too high, etc.), which will affect the coloring effect and baking effect of food and reduce the user's baking experience.

[0004] Therefore, it is urgent to solve the problem of an intelligent, efficient, and oven preheating method that meets the baking requirements of the internal environment temperature and connects the baking requirements while ensuring the stability of the preheating environment, as much as possible to shorten the preheating time and save the demand for preheating resources in the current smart home field. SUMMARY

[0018] According to another aspect of the present application, there is provided a computer program product comprising a computer program, the computer program being configured to implement the oven preheating method of any of the embodiments of the present application when executed by a processor.

[0019] The oven preheating method of the present invention includes: determining the oven's baking control parameters based on the user's baking needs, and determining the target temperature and fan operation mode of the oven's preheating task based on the baking control parameters; determining the oven's preheating control information according to the fan operation mode and the rated working power of each heating element in the oven, wherein the preheating control information includes the fan operation parameters, the oven's preheating heating element, and the working power of the preheating heating element; controlling the oven's fan to operate based on the fan operation parameters and the preheating heating element to operate based on the working power of the preheating heating element to perform the oven's preheating task, and ending the oven's preheating task when the internal temperature of the oven reaches the target temperature.

For example, inappropriate preheating temperatures or excessively low or high temperatures in the heating elements required for baking can negatively impact browning and baking results, thus reducing the user's baking experience.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first," "second," "initial," "intermediate," "candidate," "alternate," "target," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] Generally, a 70L oven includes four heating elements: a 2000W upper internal heating element, a 1000W upper external heating element, a 2500W rear heating element, and a 1200W lower heating element. The oven's maximum rated power is 3680W (230V*16A). Currently, the common method for preheating ovens, regardless of the baking mode used, is to preheat using either the upper internal and lower heating elements (total power 2000W + 1000W = 3000W) or the upper external and rear heating elements (total power 1000W + 2500W = 3500W) to increase the overall heating power and shorten the heating time. However, when the oven fan is not running, the temperature of the heating elements used for baking can easily become too low or too high, affecting the browning and baking results of the food.

[0032] The oven provided by this invention includes a processor (a data processing and control component for the oven), a back heating element, a first upper heating element (i.e., an inner upper heating element), a second upper heating element (i.e., an outer upper heating element), a lower heating element, and a fan. The processor is used to implement any one of the oven preheating methods in this invention. The first and second upper heating elements are nested together, with the first and lower heating elements arranged opposite each other. That is, the first and second upper heating elements are arranged close to the top surface of the oven and are on the same horizontal plane, while the lower heating element is arranged close to the ground surface of the oven. The back heating element is arranged inside the oven on the side away from the oven door.

[0033] The fan is used to evenly distribute heat inside the oven. The back heating element, the first upper heating element, the second upper heating element, and the lower heating element are all heating devices that can provide heat, thereby increasing the internal temperature of the oven. Specifically, Table 1 shows the rated operating power of each component of the oven of the present invention.

[0034] Table 1

[0035] Component name Load rated operating power / W Back heating tube 2500 Upper inner heating tube 2000 Upper outer heating tube 1000 Lower heating tube 1200 Fan 20

[0036] As can be seen from Table 1, the rated operating power of the back heating tube is greater than that of the first upper heating tube, the rated operating power of the first upper heating tube is greater than that of the lower heating tube, the rated operating power of the lower heating tube is greater than that of the second upper heating tube, and the rated operating power of the second upper heating tube is greater than that of the fan.

[0037] Figure 1This is a flowchart illustrating an oven preheating method provided by the present invention. This embodiment is applicable to rapid, efficient, and high-quality oven preheating to improve baking results and the user's baking experience. The method can be executed by a controller provided by the present invention, which can be implemented in hardware and / or software. In one specific embodiment, the controller can be integrated into an electronic device. The following embodiments will illustrate this using the example of the controller integrated into an electronic device. (Refer to...) Figure 1 The method specifically includes the following steps:

[0038] S101. Determine the oven's baking control parameters based on the user's baking needs, and determine the target temperature and fan operation mode for the oven's preheating task based on the baking control parameters.

[0039] Here, a user's baking needs can be understood as the purpose of using the oven. For example, what food does the user want to bake, what dishes does the user want to prepare, and what baking mode does the user need to control the oven to bake the food? The oven's baking control parameters can be understood as the operating parameters of the oven when performing a baking task, including the heating elements used and their power. These parameters differ depending on the type of food being baked and the purpose of the baking. Placing food directly into an unpreheated oven will keep it at a low temperature until the oven reaches the set temperature (baking temperature), prolonging baking time and affecting the texture and taste. To ensure optimal baking results and shorten baking time, ovens are preheated before baking. A preheated oven can transfer heat to the food more quickly and evenly, saving baking resources while maximizing baking results. This invention analyzes the user's baking needs, first determining the oven's baking control parameters based on these needs, and then determining the target temperature for the oven's preheating task and the fan operation mode based on these parameters. In other words, it aims to make the preheated oven environment as close as possible to the baking environment, improving the baking effect and the smoothness of the baking process. The target temperature for the preheating task can be understood as the oven's preheating temperature value, and the fan operation mode can be understood as whether the fan is needed for the preheating task and in what mode it operates.

[0040] For example, suppose the baking control parameters for the food indicate that it needs to be baked at a temperature of 200℃, and the fan needs to operate during the baking process. In this case, the target temperature for the preheating task is 200℃, and the fan will operate in a fan-activated mode. Alternatively, suppose the baking control parameters indicate that the food needs to be baked at a temperature of 220℃, and the fan does not need to operate during the baking process. In this case, the target temperature for the preheating task is 220℃, and the fan will operate in the first and second preheating stages, but will not operate in the third preheating stage. After the third preheating stage, the preheating environment will transition to the baking environment. The fan not operating is to better execute the baking task and improve the user's food baking experience.

[0041] S102. Determine the preheating control information of the oven based on the fan operation mode and the rated working power of each heating element in the oven.

[0042] The oven includes four heating elements: a back heating element, a first upper heating element (i.e., an inner upper heating element), a second upper heating element (i.e., an outer upper heating element), and a lower heating element. The rated operating power can be understood as the maximum operating power at which the heating element can operate safely, stably, and efficiently. In this invention, the rated operating power of the inner upper heating element is 2000W, the rated operating power of the outer upper heating element is 1000W, the rated operating power of the back heating element is 2500W, and the rated operating power of the lower heating element is 1200W. The oven's preheating control information can be understood as the components that need to operate when the oven performs preheating work, and the operating parameters of each component, such as the fan operating parameters, the oven's preheating heating elements, and their operating power.

[0043] Specifically, the fan operating parameters include the fan's operating status (started and not started) and its operating power. The preheating heating element can be understood as the heating element that performs preheating work, and it can be at least one of a back heating element, an upper inner heating element, an upper outer heating element, and a lower heating element. This invention combines baking control information and the rated operating power of each heating element in the oven to determine the oven's preheating components and their operating power, in order to develop targeted preheating solutions and improve the accuracy and effectiveness of the oven's preheating task.

[0044] S103. Control the oven fan to operate based on the fan operating parameters, and the preheating heating tube to operate based on the working power of the preheating heating tube, so as to perform the oven preheating task, and end the oven preheating task when the internal temperature of the oven reaches the target temperature.

[0045] Specifically, once the oven's internal temperature reaches the target temperature, the preheating process is considered complete, and the oven environment is ready for high-quality baking. The preheating process is then terminated to avoid wasting resources. Furthermore, a preheating completion indicator can be issued after the preheating process is finished to prompt the user to begin baking.

[0046] Controlling the oven fan based on its operating parameters can be understood as controlling the fan to operate at its working power when the fan is in the "start" state, and not starting the fan when it is in the "backup" state. For example, assuming the fan is in the "start" state with a working power of 30W, and the preheating heating elements are a back heating element and an upper external heating element with a rated working power of 1000W and a back heating element with a rated working power of 2500W, then "controlling the oven fan to operate based on its operating parameters, and the preheating heating elements operating based on their working power" means controlling the fan to operate at 30W, the upper external heating element at 1000W, and the back heating element at 2500W.

[0047] Optionally, after the oven preheating task is completed, the oven preheating method of the present invention further includes: determining whether a baking instruction has been received; if a baking instruction is received, controlling the oven to operate based on baking control parameters to bake the food to be processed in the oven.

[0048] Baking instructions can be understood as user-triggered instructions to start baking operations. For example, the instruction to close the oven door after the user puts food in the oven, or the baking start instruction sent by the user based on the oven information interaction interface, are used to instruct the oven to start baking operations.

[0049] The technical solution of the above embodiments determines the baking control parameters used for the baking task based on the user's baking needs, and determines the preheating requirements of the oven (including but not limited to the target temperature and fan operation mode) in combination with the baking control parameters, so that the internal environment of the oven is more suitable for performing the baking task after preheating, thereby improving the baking effect of the food. It also determines the fan operation parameters, the oven's preheating heating tube and its working power based on the fan operation mode and the rated working power of each heating tube in the oven, and controls the oven to operate according to the target temperature, fan operation parameters, oven's preheating heating tube and its working power, etc., to perform the oven preheating task with high quality, improve the preheating effect and the control accuracy of the preheating work, and shorten the preheating time as much as possible while ensuring the stability of the preheating environment and saving the amount of preheating resources required, thereby improving the baking quality of the food and the user's baking experience. This solution addresses the issue of excessively long preheating times caused by using heating elements in the baking mode, and also resolves the problem of oven temperatures not meeting baking requirements when using high-power heating elements. For example, inappropriate preheating temperatures or excessively low or high temperatures in the heating elements required for baking can negatively impact browning and baking results, thus reducing the user's baking experience.

[0050] Figure 2 This is a schematic flowchart of another oven preheating method provided by the present invention. Based on the above embodiments, this embodiment provides a preferred oven preheating method, which is essentially an oven preheating method with more complete process details. Specifically, as shown... Figure 2 As shown, the method includes:

[0051] S201. Analyze the user's baking needs to obtain the starting baking temperature and fan operation status of the oven's baking task.

[0052] Depending on the complexity and logic of the food being baked, a baking task may include one or multiple baking stages, and the baking parameters (temperature, duration, type of heating element) may differ between stages. The initial baking temperature can be understood as the baking temperature of the first baking stage, and the fan operating status can be understood as the fan operating information of the first baking stage. Since the preheated environment is connected to the first baking stage, using the baking parameters of the first stage as the preheating target allows for better execution of the food baking task and improves the baking effect.

[0053] There are various ways to determine baking requirements. This invention does not limit the specific method of determination. For example, the methods of determining baking requirements include at least one of the following:

[0054] 1) Determine baking needs based on baking data triggered by the user through the information interaction interface.

[0055] The information interaction interface can be the oven's touchscreen display or a corresponding mobile control terminal. This interface can interact with the oven's controller. Baking data triggered by the user through this interface can be understood as the user directly inputting baking parameters, such as the required temperature, heating element, and fan operating parameters. The system parses these user-input baking parameters and converts them into a data format that the controller can recognize, thus obtaining the baking requirements.

[0056] 2) Determine baking needs based on the type of food triggered by the user through the information interaction interface.

[0057] Baking requirements include, but are not limited to, the baking temperature and the heating element required for baking. Different types of food require different baking temperature ranges. For example, the baking temperature range for cookies is 150℃-180℃, for pies it is 180℃-200℃, for roasted meat it is 150℃-200℃, and for roasted fish it is 150℃-180℃, etc. The baking temperature and target preheating temperature can be obtained based on the food type input through the information interface. Similarly, different types of food require different heating elements. For example, baking cookies requires heating elements A and B, baking pies requires heating elements A and C, and roasted fish requires heating elements C and B, etc. The heating elements required for baking and preheating can be determined based on the food type input through the information interface.

[0058] 3) Determine baking requirements based on the baking mode triggered by the user through the information interaction interface.

[0059] The oven includes multiple pre-set baking modes, each with parameters such as baking temperature, heating element, and heating element power. By analyzing the baking mode, the oven's baking requirements can be directly determined, making it an efficient way to identify baking needs.

[0060] The advantage of this setup is that it provides diverse and comprehensive methods for determining baking needs, ensuring that the oven can accurately receive the user's baking requirements. Furthermore, different heating elements are used for foods placed in different locations. This invention can also adjust the baking requirements based on the food's placement, thereby determining the relevant control information for the preheating task and improving the quality of the preheating process.

[0061] S202. Based on the initial baking temperature and the fan operating status, determine the target temperature and the fan operating mode.

[0062] Determining the target temperature and fan operation mode based on the initial baking temperature and fan status can be understood as setting the initial baking temperature as the target temperature, and determining the fan operation mode for the preheating task based on the fan operation status of the baking task. For example, when the fan operation status of the baking task is "fan on," the fan operation mode for the preheating task is determined to be continuous operation; when the fan operation status of the baking task is "fan off," the fan operation mode for the preheating task is determined to be "fan on first, then off." Specifically, when the fan is on, it can circulate the heat inside the chamber, thereby evenly distributing the heat within the chamber. When the fan is off, the temperature is higher closer to the heating element.

[0063] The purpose of this setting is to determine the target temperature and fan operation mode of the preheating task individually based on the initial baking temperature and fan operation status of the baking task, so as to speed up the preheating process as much as possible while ensuring the preheating effect.

[0064] S203. Determine whether the fan operation mode is fan start.

[0065] If the fan operation mode is fan start, then execute S204; otherwise, if the fan operation mode is fan not start, that is, if the fan operation mode is fan not start, then execute S205.

[0066] S204. Based on the rated operating power of the fan, the rated operating power of the oven, and the rated operating power of each heating element in the oven, determine the preheating control information.

[0067] The preheating control information includes the components that need to operate when the oven performs preheating, as well as the operating parameters of each component. Examples include the fan operating parameters, the oven's preheating heating element, and its operating power. It's important to note that when the fan is running, the fan operating power in the fan operating parameters is the fan's rated operating power; when the fan is not running, the fan operating power in the fan operating parameters is 0W.

[0068] Specifically, in order to ensure that the oven can operate safely and stably, the total working power of the oven must not exceed the oven's rated working power. That is, the sum of the working power of the various operating components of the oven (such as heating elements, heating tubes, and fans) must not exceed the oven's rated working power.

[0069] When the fan is running, the temperature and heat distribution inside the oven are uniform. In this way, the present invention will select the maximum heat supply method for preheating within the rated working power of the oven load. That is, within the rated working power of the oven load, the combination of heating tubes with the largest sum of working power will be selected to perform the preheating work, thereby improving the efficiency of the preheating work.

[0070] In one specific implementation, S204 may include:

[0071] 1) Determine the fan operating parameters based on the fan's rated load power, and determine the oven's maximum heating element operating power based on the fan's rated load power and the oven's rated load power.

[0072] In fan-operated mode, the oven operates both the heating element and the fan. Therefore, the maximum operating power that can be allocated to the heating element (i.e., the maximum heating element operating power) is the difference between the rated operating power of the fan and the rated operating power of the oven. For example, assuming the oven's rated operating power is 3680W and the fan's rated operating power is 30W, then the maximum heating element operating power of the oven is 3650W (3680W - 30W = 3650W).

[0073] 2) Determine the preheating heating element and its working power based on the maximum working power of the heating element and the rated working power of each heating element in the oven.

[0074] Among them, the preheating heating tube can be understood as the heating tube that performs the preheating task. There is at least one preheating heating tube. Under normal circumstances, the working power of the heating tube is the rated working power of the heating tube under load. Under special circumstances (for example, when a specific heating tube is required to perform a specific heating task), the working power of the heating tube is a power within the rated working power of the heating tube under load.

[0075] For example, assume the heating element's operating power is its rated load power. The rated load power of the upper inner heating element is 2000W, the upper outer heating element is 1000W, the rear heating element is 2500W, and the lower heating element is 1200W. The sum of the operating power of the upper inner and outer heating elements is 3000W, the sum of the operating power of the upper inner and rear heating elements is 4000W, the sum of the operating power of the upper inner and lower heating elements is 3200W, the sum of the operating power of the upper outer and rear heating elements is 3500W, the sum of the operating power of the upper outer and lower heating elements is 2200W, and the sum of the operating power of the rear and lower heating elements is 3700W. Based on the rated load power of each heating element in the oven, the operating power of each individual heating element and the combined power of various heating element combinations can be obtained. Combining this with the maximum operating power of the heating element, the preheating heating element and its operating power can be determined. In this invention, the upper external heating tube and the back heating tube are preferred as preheating heating tubes. The rated working power of the upper external heating tube is 1000W, and the rated working power of the back heating tube is 2500W.

[0076] The advantage of this setting is that it allows for the specification of personalized preheating control information in conjunction with baking control parameters, thereby improving preheating efficiency while ensuring preheating effect.

[0077] S205. Determine the target heating element based on the baking control parameters, and determine the preheating control information based on the rated operating power of the target heating element, the rated operating power of the fan, the rated operating power of the oven, and the rated operating power of each heating element in the oven.

[0078] To ensure a smooth transition between preheating and baking while maximizing preheating efficiency, this invention divides the preheating process into three stages. The target heating element can be understood as the heating element used in the final stage of preheating, which is also the heating element used in the first stage of baking. This avoids frequent switching of heating elements, improves the baking effect, and reduces the difficulty of controlling the oven.

[0079] Specifically, determining the preheating control information based on the rated operating power of the target heating element, the rated operating power of the fan, the rated operating power of the oven, and the rated operating power of each heating element in the oven can be understood as determining the control information for the three preheating stages based on the rated operating power of the target heating element, the rated operating power of the fan, the rated operating power of the oven, and the rated operating power of each heating element in the oven.

[0080] In one specific implementation, S205 may include:

[0081] 1) Divide the oven preheating task into three preheating stages, and determine the end conditions of the first preheating stage and the second preheating stage based on the target temperature and the preheating requirements of each stage.

[0082] The preheating requirements for each stage can be understood as the preheating targets for each stage. Reaching the preheating target signifies the end of the current preheating stage, allowing the start of the next stage. The preheating target for the third stage is the target temperature. Stage preheating requirements are generally displayed as a percentage of the target temperature. For example, the preheating target for the first stage is 70% of the target temperature, and the preheating target for the second stage is 90% of the target temperature. The specific percentage is related to the preheating control logic, which is not limited in this invention. The end condition for a preheating stage can be understood as a specific temperature value. When the temperature inside the oven reaches this value, the current preheating stage ends. Assuming the target temperature is 200℃, the preheating target for the first stage is 70% of the target temperature, and the preheating target for the second stage is 90% of the target temperature, then the end condition for the first preheating stage is when the oven temperature reaches 140℃, and the end condition for the second preheating stage is when the oven temperature reaches 180℃.

[0083] 2) Based on the rated operating power of the fan, the rated operating power of the oven, the rated operating power of each heating element in the oven, and the end conditions of the first preheating stage, determine the first preheating control information of the oven.

[0084] The first preheating control information is the oven control information for the first preheating stage. This stage is the rapid heating stage. During this stage, the fan will be turned on, and the combination of heating elements with the largest sum of working power will be selected as much as possible within the rated working power of the oven to perform the preheating work. That is, the fan will be turned on and the upper external heating element and the back heating element will be selected as the preheating heating elements. The rated working power of the upper external heating element is 1000W, and the rated working power of the back heating element is 2500W.

[0085] 3) Based on the rated operating power of the fan, the rated operating power of the oven, the rated operating power of the target heating element, and the end conditions of the second preheating stage, determine the second preheating control information of the oven.

[0086] 4) Determine the third preheating control information of the oven based on the oven's rated operating power and the target heating element's rated operating power.

[0087] The second preheating control information refers to the oven control information for the second preheating stage, and the third preheating control information refers to the oven control information for the third preheating stage. The second and third preheating stages are a stable transition phase, designed to adjust the oven's operating components to be as similar as possible to the first stage of the baking task while ensuring the preheating effect. Specifically, in both the second and third preheating stages, the preheating heating element is the target heating element, i.e., the heating element of the oven's first baking stage. The only difference is that the fan will still run in the second preheating stage. This setting is intended to quickly stabilize the environment inside the oven. When the environment inside the oven is stable and the temperature reaches 90% of the target temperature, the fan is turned off, and the target heating element continues to perform preheating work to preheat the oven to the target temperature.

[0088] It is important to note that, regardless of the preheating stage, the total operating power of the oven must not exceed its rated operating power. If it does, the operating power of some heating elements must be reduced or the heating elements must be replaced.

[0089] 5) According to the time sequence of the three preheating stages, the first preheating control information, the second preheating control information, and the third preheating control information are combined to obtain the preheating control information.

[0090] Specifically, combining the first, second, and third preheating control information according to the time sequence of the three preheating stages can be understood as splicing them together in the order of their respective preheating control information to obtain complete preheating control information.

[0091] The advantage of this setup is that by using a three-stage control method, it can eliminate the impact of preheating load on the baking process while rapidly preheating, providing a stable and smooth preheating environment that seamlessly connects the baking process, thereby improving the baking effect and the user's baking experience.

[0092] S206. Control the oven fan to operate based on the fan operating parameters, and the preheating heating tube to operate based on the working power of the preheating heating tube, so as to perform the oven preheating task, and end the oven preheating task when the internal temperature of the oven reaches the target temperature.

[0093] Figure 3 This is a schematic diagram of the first oven preheating curve provided by the present invention. Figure 4 This is a schematic diagram of the second oven preheating curve provided by the present invention. Figure 5 This is a schematic diagram of the third type of oven preheating curve provided by the present invention. Figure 3 , Figure 4 and Figure 5 The solid line in the graph represents the power curve, and the dashed line represents the temperature curve. Figure 3 This is a schematic diagram of the oven preheating curve under existing preheating methods. Figure 4 This is a schematic diagram of the oven preheating curve when the fan is running at startup. Figure 5 This is a schematic diagram of the oven preheating curve when the fan is not running, specifically a schematic diagram of the oven preheating curve under the three-stage preheating method. From Figures 3-5 As can be seen, the technical solution of the present invention can significantly shorten the preheating time. Specifically, Figure 3 The method shown requires approximately 8 minutes to preheat to 200°C. Figure 4 and Figure 5 The method shown requires approximately 5.5 minutes to preheat to 200°C.

[0094] The technical solution of the above embodiments determines the baking control parameters used for the baking task based on the user's baking needs, and determines the preheating requirements of the oven (including but not limited to the target temperature and fan operation mode) in combination with the baking control parameters, so that the internal environment of the oven is more suitable for performing the baking task after preheating, thereby improving the baking effect of the food. It also determines the fan operation parameters, the oven's preheating heating tube and its working power based on the fan operation mode and the rated working power of each heating tube in the oven, and controls the oven to operate according to the target temperature, fan operation parameters, oven's preheating heating tube and its working power, etc., to perform the oven preheating task with high quality, improve the preheating effect and the control accuracy of the preheating work, and shorten the preheating time as much as possible while ensuring the stability of the preheating environment and saving the amount of preheating resources required, thereby improving the baking quality of the food and the user's baking experience. This solution addresses the issue of excessively long preheating times caused by using heating elements in the baking mode, and also resolves the problem of oven temperatures not meeting baking requirements when using high-power heating elements. For example, inappropriate preheating temperatures or excessively low or high temperatures in the heating elements required for baking can negatively impact browning and baking results, thus reducing the user's baking experience.
