[0002] This application claims priority to Chinese patent application filed on July 11, 2024, application number 202410927540.8, entitled "Cooking Equipment Control Method, Apparatus, Computer Equipment and Cooking Equipment", the entire contents of which are incorporated herein by reference.

Cooking equipment with steam mode, such as steam heaters and steam ovens, has gradually become the main kitchen appliances, providing many conveniences for family life.

[0005] However, traditional cooking appliances with steam modes often suffer from slow steam generation within the inner cavity.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] The cooking device control method provided in this application embodiment can be applied to the cooking device 100 shown in FIG. 1. The cooking device 100 may include a top heating element 101, a steam generator 102, and a controller 103. The controller 103 is communicatively connected and / or electrically connected to the top heating element 101 and the steam generator 102, respectively. A data storage system can store the data that the controller 103 needs to process. The data storage system can be integrated into the controller 103 or placed in the cloud or other network servers. In response to a device start command for the cooking device 100, the controller 103 can acquire the cooking parameters of the cooking device 100, including the cooking mode and cooking temperature. When the cooking mode is steam mode, the controller controls the top heating element 101 and the steam generator 102 in the cooking device 100 to operate simultaneously. Based on the temperature range to which the cooking temperature belongs, the controller determines the corresponding operating control parameters of the cooking device 100 within the temperature range and controls the operation of the cooking device 100 based on the operating control parameters.

[0045] The cooking device 100 can be any smart kitchen cooking device with steam cooking function, such as a steam oven or a steam-grill combination appliance. For ease of understanding, the following examples will use built-in steam ovens.

[0046] The top heating element 101 is a heating element, such as a top heating tube, used to provide heat to the cooking liner in the cooking appliance 100. In some embodiments, the top heating element 101 may be disposed on the top outer wall of the cooking liner to provide heat to the cooking liner.

[0047] Steam generator 102 is a device component used to generate steam. By controlling the operation of steam generator 102, a steam cooking environment can be provided for cooking equipment 100 to meet user needs. In some embodiments, steam generator 102 can be a water-boiling type steam generator. In order to further improve the steam generation efficiency, in other embodiments, steam generator 102 can be an instantaneous type steam generator. Compared with water-boiling type steam generators, instantaneous type steam generators have advantages such as small size, low cost, low energy consumption, and large steam output.

[0048] The controller 103 can be any control device with logic processing capabilities, such as an MCU or a microcontroller.

[0049] In some embodiments, as shown in FIG2, a cooking device control method is provided. Taking the application of the method to the controller 103 in FIG1 as an example, the method includes the following steps S202 to S208.

[0050] S202, in response to a device start command for a cooking device, obtains the cooking mode and cooking temperature of the cooking device.

[0051] Among them, the device start command is used to instruct the cooking equipment to start operation and cook the food placed inside the equipment. The device start command can be triggered by the user when food needs to be cooked. For example, after the user places the food to be cooked into the cooking cavity, the device start command can be triggered directly by the cooking equipment, or it can be triggered by the relevant application of the cooking equipment. It can also be triggered automatically through preset time events. For example, the user can put the food into the cooking equipment first, set the cooking start time, and when the cooking start time is reached, the device start command for the cooking equipment can be automatically triggered.

[0052] Cooking mode and cooking temperature are both cooking parameters used to reflect the user's actual cooking needs. The cooking mode refers to the cooking method used when processing the food in the cooking equipment. Different cooking modes correspond to different cooking methods. Different cooking equipment can have different usable modes. For example, a steam oven may have steaming, baking, and steam-bake modes, with steaming and steam-bake modes being steam modes. Users can select one or more cooking modes from the available modes of the cooking equipment, and the controller will then operate the cooking equipment according to the selected mode. The cooking temperature is the target temperature that the user expects to achieve during the cooking process, i.e., the user-set temperature.

[0053] Specifically, in response to a device start command for the cooking equipment, the controller acquires the cooking parameters of the cooking equipment, including the cooking mode and cooking temperature.

[0054] In some embodiments, the controller, in response to a device start command for the cooking device, can also obtain the cooking time of the cooking device, which is the target cooking time required by the user.

[0055] S204 corresponds to the determination that the cooking mode is steam mode, and controls the top heating element and steam generator in the cooking device to operate simultaneously.

[0056] Steam mode refers to a cooking mode that requires the use of steam during the cooking process. Steam mode can be a cooking mode that uses only steam, such as the steaming mode of a steam oven. It can also include all cooking modes that involve the use of steam, such as the steaming mode and steam-bake mode of a steam oven, all of which can be considered steam modes.

[0057] Specifically, the controller acquires the cooking mode of the cooking device. If the user selects the steam mode, preheating is not required. Instead, the controller directly controls the top heating element and the steam generator in the cooking device to operate simultaneously, thereby enabling the cooking pot of the cooking device to quickly generate a large amount of steam.

[0058] S206, determine the corresponding operating control parameters of the cooking equipment within the temperature range of the cooking temperature.

[0059] The temperature range can be a range parameter obtained by pre-dividing the heating temperature range that can be achieved by steam heating. Designers can divide the cooking equipment into multiple temperature ranges according to the heating temperature that the cooking equipment can achieve when steam heating and the preset control precision. The specific number of temperature ranges is not limited in this embodiment.

[0060] Assuming the cooking equipment can reach a heating temperature of 40 to 100 degrees Celsius when using steam heating, for lower precision, designers can simply divide the cooking equipment into two temperature ranges. For example, a low-temperature range could be defined as temperatures greater than or equal to 40 degrees Celsius and less than or equal to 70 degrees Celsius, and a high-temperature range could be defined as temperatures greater than 70 degrees Celsius and less than or equal to 100 degrees Celsius. For higher precision, designers can divide the cooking equipment into three temperature ranges. For example, a low-temperature range could be defined as temperatures greater than or equal to 40 degrees Celsius and less than or equal to 70 degrees Celsius, a medium-temperature range as temperatures greater than 70 degrees Celsius and less than or equal to 90 degrees Celsius, and a high-temperature range as temperatures greater than 90 degrees Celsius and less than or equal to 100 degrees Celsius.

[0061] Operating control parameters are the control parameters that the controller uses to control the operation of the cooking equipment. Understandably, the specific parameter types included in the operating control parameters are related to the equipment components required during the subsequent operation of the cooking equipment. Cooking equipment has different operating control parameters for different temperature ranges.

[0062] Specifically, the controller can match the acquired cooking temperature with multiple pre-defined temperature ranges, and determine the pre-defined temperature range that matches the cooking temperature as the temperature range to which the cooking temperature belongs. Then, based on the temperature range to which the cooking temperature belongs, the controller can determine the corresponding operating control parameters of the cooking equipment within the temperature range.

[0063] In one embodiment, the controller can determine a list of operating control parameters matching the temperature range based on the temperature range to which the cooking temperature belongs and the pre-set correspondence between temperature ranges and operating control parameter lists. The operating control parameter list contains operating control parameters corresponding to each temperature within the temperature range. The controller can then further determine operating control parameters matching the cooking temperature from the operating control parameter list, and define these operating control parameters as the corresponding operating control parameters for the cooking device within the temperature range.

[0064] S208 controls the operation of cooking equipment based on operating control parameters.

[0065] Specifically, after determining the operating control parameters of the cooking equipment within the temperature range, the controller can control the operation of the cooking equipment based on the operating control parameters.

[0066] In the aforementioned cooking equipment control method, upon startup, the cooking mode and cooking temperature of the cooking equipment are acquired. If the cooking mode is determined to be steam mode, the top heating element and steam generator in the cooking equipment are directly controlled to operate simultaneously, achieving the effect of rapidly generating a large amount of steam within the cooking pot. Furthermore, by pre-dividing the cooking equipment into multiple temperature ranges, after obtaining the cooking temperature, the corresponding operating control parameters for the cooking equipment within that temperature range can be determined. This ensures that the operating control parameters used for subsequent operation of the cooking equipment are more consistent with the actual usage scenario, effectively reducing unnecessary energy consumption during operation and improving energy efficiency.

[0067] Heating and maintaining the temperature are two operational stages that a cooking device needs to go through during the cooking process. In some embodiments, the operational control parameters include the stage control parameters for the heating stage and the stage control parameters for the maintaining the temperature stage. As shown in Figure 3, in step S206, the operational control parameters of the cooking device within the temperature range to which the cooking temperature belongs are determined, including steps S302 to S306.

[0068] S302, determine the stage control parameters of the cooking equipment during the heating stage based on the cooking temperature and the temperature range to which the cooking temperature belongs.

[0069] The heating stage refers to the process by which the cooking equipment heats the inner pot of the cooking vessel using steam and / or other heating components during the operation of steam mode, so that the temperature of the inner pot reaches or approaches the cooking temperature.

[0070] The stage control parameters during the heating phase refer to the control parameters used by the controller in controlling the operation of the cooking equipment to bring the temperature of the inner pot of the cooking vessel to or near the cooking temperature.

[0071] Specifically, since the heating phase is to raise the temperature of the cooking pot of the cooking equipment to reach or approach the cooking temperature, the controller can determine the phase control parameters of the cooking equipment during the heating phase based on the cooking temperature and the temperature range to which the cooking temperature belongs.

[0072] In some embodiments, the controller can first determine the heating operation components that the cooking device needs to use during the heating phase based on the temperature range to which the cooking temperature belongs, and then determine the phase control parameters of the cooking device during the heating phase based on the heating operation components and the cooking temperature.

[0073] S304, based on the temperature range, determines the temperature-maintaining operation components of the cooking equipment during the temperature-maintaining phase.

[0074] The temperature maintenance stage is the subsequent stage after the heating stage. It can be considered as maintaining the temperature of the cooking pot in the cooking equipment at a level close to the cooking temperature to cook the food inside. Once the cooking equipment has reached or approached the cooking temperature of the cooking pot through the heating stage, it enters the temperature maintenance stage. The controller needs to control the cooking equipment to continue operating according to the corresponding stage control parameters for the temperature maintenance stage.

[0075] The temperature maintenance components refer to the equipment components used by the cooking equipment during the temperature maintenance phase. When the cooking equipment is running in steam mode, it tends to produce a lot of condensation in the inner pot. To reduce the amount of condensation remaining at the bottom of the inner pot after steaming, the controller can operate the corresponding equipment components during the temperature maintenance phase to remove the condensation, thus simplifying cleaning for the user. Because the amount of condensation produced by the cooking equipment varies depending on the temperature range, the corresponding equipment components required during the temperature maintenance phase may also differ.

[0076] Specifically, the controller can determine the temperature-maintaining components of the cooking equipment during the temperature maintenance phase based on the temperature range to which the cooking temperature belongs.

[0077] In some embodiments, the controller can invoke a preset correspondence between temperature range and temperature-maintaining operating components, find the temperature-maintaining operating component that matches the temperature range to which the cooking temperature belongs, and determine the temperature-maintaining operating component as the temperature-maintaining operating component of the cooking device during the temperature maintenance phase.

[0078] S306, Based on the temperature maintenance operation component, determine the stage control parameters of the cooking equipment during the temperature maintenance phase.

[0079] The stage control parameters for the temperature maintenance phase can also be considered as the stage control parameters used by the controller when controlling the temperature maintenance operation components. It is understood that the cooking equipment may use a single or multiple temperature maintenance operation components during the temperature maintenance phase. This embodiment does not limit the specific number of temperature maintenance operation components, and the corresponding stage control parameters will differ depending on the temperature maintenance operation components used.

[0080] Specifically, after determining the temperature-maintaining operation components of the cooking equipment during the temperature-maintaining phase, the controller can determine the phase control parameters of the cooking equipment during the temperature-maintaining phase based on the temperature-maintaining operation components.

[0081] In some embodiments, after the controller identifies the temperature-maintaining component, it can determine the control parameters of the temperature-maintaining component according to the temperature-maintaining mode corresponding to the temperature-maintaining component, and determine the control parameters of the temperature-maintaining component as the stage control parameters of the cooking device in the temperature-maintaining stage.

[0082] In the above embodiments, by determining the stage control parameters of the cooking equipment during the heating stage and the temperature maintenance stage according to the temperature range to which the cooking temperature belongs, the accuracy of the operation control of the cooking equipment during the heating stage and the temperature maintenance stage can be effectively improved, unnecessary energy consumption during the operation of the cooking equipment can be reduced, and energy utilization efficiency can be improved.

[0083] The specific determination process for the stage control parameters of the cooking equipment during the heating stage and the temperature maintenance stage may differ depending on the temperature range to which the cooking temperature belongs. The following examples illustrate several implementation methods.

[0084] In some embodiments, the stage control parameters of the cooking device during the heating phase include the heating end temperature. S302, determining the stage control parameters of the cooking device during the heating phase based on the cooking temperature and the temperature range to which the cooking temperature belongs includes: if the temperature range to which the cooking temperature belongs is a low temperature range or a medium temperature range, determining the heating end temperature of the cooking device during the heating phase based on the cooking temperature and a preset safety temperature coefficient.

[0085] When the cooking temperature required by the user is in the low-temperature or medium-temperature range, it means that the cooking temperature to be reached during cooking is not a high-temperature temperature, and the time required to reach the cooking temperature will not be too long. Therefore, in the low-temperature or medium-temperature range, the stage control parameters of the cooking equipment during the heating phase can include the heating end temperature.

[0086] The heating-end temperature is a parameter used to determine whether the heating phase of a cooking appliance is complete. It can also be considered a parameter for determining when the temperature-maintaining phase of the cooking appliance starts. When the temperature of the inner pot of the cooking appliance reaches the heating-end temperature, it means that the cooking appliance has reached or is close to the required cooking temperature, and subsequent cooking only needs to maintain this temperature.

[0087] The final heating temperature can be determined based on the cooking temperature and a preset safety temperature coefficient. This safety temperature coefficient is a calculated factor pre-set by the designer. In actual operation, if the cooking temperature is directly used as the final heating temperature, the actual cooking temperature may exceed the user-set temperature during the subsequent temperature maintenance phase, affecting the final taste. Therefore, designers can pre-set a safety temperature coefficient and determine the final heating temperature using this coefficient and the cooking temperature. This effectively reduces the impact of overheating during cooking and improves the accuracy of the cooking equipment. Understandably, the final heating temperature should be lower than the cooking temperature.

[0088] Specifically, when the controller determines that the cooking temperature falls within a low or medium temperature range, it can call up a pre-set safety temperature coefficient and determine the end temperature of the heating phase of the cooking equipment based on the user-set cooking temperature and the safety temperature coefficient.

[0089] In some embodiments, the controller can determine the heating end temperature based on the product of the cooking temperature and the safety temperature coefficient. If the product is not an integer, the largest integer less than the product is determined as the heating end temperature; if the product is an integer, the product is determined as the heating end temperature. For example, if the cooking temperature is 90 degrees Celsius and the safety temperature coefficient is 0.95, then 85 degrees Celsius can be determined as the heating end temperature.

[0090] In other embodiments, the controller can determine the end temperature of the heating process based on the difference between the cooking temperature and the safety temperature coefficient. For example, if the cooking temperature is 90 degrees and the safety temperature coefficient is 5 degrees, then 85 degrees can be determined as the end temperature of the heating process.

[0091] In the above embodiments, when the cooking temperature falls within a low or medium temperature range, the heating end temperature of the cooking equipment during the heating phase can be quickly determined by using a pre-set safety temperature coefficient and the user-set cooking temperature. This provides accurate stage operating parameters for the subsequent operation of the cooking equipment during the heating phase, effectively improving the accuracy and efficiency of the cooking equipment.

[0092] In some embodiments, after the controller determines that the stage control parameter of the cooking device during the heating phase is the heating end temperature, it can control the operation of the top heating element and steam generator of the cooking device to quickly generate steam and rapidly heat the temperature in the cooking pot to the heating end temperature.

[0093] In addition to the aforementioned low-temperature and medium-temperature ranges, in some embodiments, the stage control parameters of the cooking device during the heating phase include steam pre-generation time, rapid heating temperature, and heating end temperature. S302, based on the cooking temperature and the temperature range to which the cooking temperature belongs, the stage control parameters of the cooking device during the heating phase are determined, including: if the temperature range to which the cooking temperature belongs is a high-temperature range, obtaining the steam pre-generation time and rapid heating temperature matching the high-temperature range; and determining the heating end temperature of the cooking device during the heating phase based on the cooking temperature and a preset safety temperature coefficient.

[0094] When the user sets the cooking temperature to a high range, it means the cooking equipment needs a longer heating time to reach that temperature. During this heating process, the prolonged operation of the steam generator can easily lead to excessive condensation in the cooking pot. Therefore, to reduce the amount of condensation in the cooking pot during the heating phase, the stage control parameters of the cooking equipment during the heating phase can include steam pre-generation time, rapid heating temperature, and heating end temperature.

[0095] Among them, the steam pre-generation time refers to the duration during which the steam generator and the top heating element operate together when the device is started. By controlling the steam generator and the top heating element to operate together for the steam pre-generation time immediately when the device is started, a large amount of steam can be quickly generated in the cooking pot of the cooking device, which can improve the cooking effect and enhance the user experience.

[0096] The rapid heating temperature is the cooking temperature that the cooking equipment needs to reach quickly during the heating phase. If the top heating element and steam generator are continuously used to achieve heating at higher cooking temperatures, it will not only result in slow heating and affect the cooking effect, but also easily lead to a large amount of condensation in the inner pot due to the prolonged operation of the steam generator. Therefore, in order to accelerate the heating speed of the cooking equipment and reduce the condensation content in the inner pot, the controller can stop the steam generator after controlling the top heating element and steam generator to run for the pre-steam generation time, and switch to controlling other heating elements to assist in the operation, thereby achieving rapid heating and reducing condensation. The rapid heating temperature is a parameter used to determine whether the rapid heating process is complete. When the temperature of the inner pot of the cooking equipment reaches the rapid heating temperature, it indicates that the rapid heating of the cooking equipment is complete, and subsequent control can continue.

[0097] Understandably, in order to ensure the taste of the cooked food, the rapid heating temperature is lower than the heating end temperature. That is, the controller will not directly control the rapid heating to make the temperature of the cooking pot close to or reach the cooking temperature. Instead, it will set an intermediate temperature, namely the rapid heating temperature. After the temperature of the cooking pot is raised to the rapid heating temperature, subsequent control can continue, such as restarting the steam generator to ensure the taste of the cooked food.

[0098] Specifically, when the controller determines that the cooking temperature falls within a high-temperature range, it can directly retrieve the steam pre-generation time and rapid heating temperature matching the high-temperature range from the storage area. Understandably, both the steam pre-generation time and rapid heating temperature can be determined by the designer based on experimental or empirical data. In some embodiments, the steam pre-generation time can be 90 seconds, and the rapid heating temperature can be 60 degrees Celsius.

[0099] At the same time, the controller can call the pre-set safety temperature coefficient and determine the end temperature of the heating phase of the cooking equipment based on the cooking temperature set by the user and the safety temperature coefficient.

[0100] In the above embodiments, when the cooking temperature falls within the high-temperature range, by determining the steam pre-generation time, rapid heating temperature, and heating end temperature of the cooking equipment during the heating phase, accurate stage operation parameters can be provided for the subsequent operation of the cooking equipment during the heating phase, effectively improving the accuracy and efficiency of the cooking equipment operation.

[0101] In some embodiments, as shown in FIG4, when the cooking temperature falls within a high temperature range, S208, the cooking device is controlled to operate based on the operating control parameters, including steps S402 to S410.

[0102] S402, when the operating time of the top heating element and the steam generator reaches the pre-steam generation time, controls the steam generator to stop operating and controls the bottom heating element of the cooking device to operate.

[0103] The bottom heating element is located on the outer wall of the bottom of the cooking pot and is used to provide heat to the cooking pot of the cooking device. For example, a bottom heating element.

[0104] Specifically, after the controller is started, it can directly control the operation of the top heating element and the steam generator, so that steam can be generated quickly in the cooking pot. When the running time of the top heating element and the steam generator reaches the pre-generation time of steam, it can be considered that the amount of steam in the cooking pot has met the previous cooking needs. The controller will then control the steam generator to stop running and control the bottom heating element of the cooking equipment to work together with the top heating element to provide heat energy to the cooking pot, so that the temperature of the cooking pot can be raised quickly.

[0105] S404, Obtain the first inner pot temperature of the cooking appliance during the operation of the top heating element and the bottom heating element.

[0106] The first inner pot temperature is a temperature parameter obtained by the temperature detection component of the cooking inner pot in the cooking equipment during the steam pre-generation period when the top heating component and the bottom heating component are running simultaneously. The inner pot temperature can also be regarded as the core temperature of the cooking equipment.

[0107] Specifically, the cooking equipment is also equipped with a temperature detection component, which can accurately detect the temperature of the inner pot. While the controller is controlling the simultaneous operation of the top and bottom heating elements, it can also control the temperature detection component to monitor the temperature of the inner pot in real time, thus obtaining the initial inner pot temperature of the cooking equipment.

[0108] S406, when the first inner tank temperature reaches the rapid heating temperature, controls the bottom heating element to stop operating and controls the steam generator to operate.

[0109] Specifically, the controller can compare the first inner pot temperature detected by the temperature detection component with the rapid heating temperature. When the first inner pot temperature reaches the rapid heating temperature, it can be considered that the cooking device has completed rapid heating. The controller can then control the bottom heating element to stop running and restart the steam generator to ensure the cooking taste of the food and improve the user experience.

[0110] S408, obtains the second inner pot temperature of the cooking appliance during the operation of the top heating element and steam generator.

[0111] The second inner pot temperature is the temperature obtained by the temperature detection component when the cooking equipment is rapidly heated up and the top heating element and steam generator are running simultaneously again.

[0112] Specifically, after the cooking equipment has rapidly heated up, the controller can continue to obtain the second inner pot temperature of the cooking equipment when the top heating element and the steam generator are running simultaneously again, based on the temperature detection component.

[0113] S410: When the temperature of the second inner pot reaches the end of the heating process, the cooking equipment is controlled to operate according to the stage control parameters of the cooking equipment during the temperature maintenance stage.

[0114] Specifically, the controller can compare the temperature of the second inner pot detected by the temperature detection component with the temperature at the end of the heating phase. When the temperature of the second inner pot reaches the temperature at the end of the heating phase, it indicates that the heating phase of the cooking equipment has been completed and it can enter the temperature maintenance phase. The controller can then control the cooking equipment to continue operating based on the phase control parameters of the temperature maintenance phase.

[0115] In the above embodiments, by determining the pre-generation time of steam, the rapid heating temperature, and the heating end temperature, the steam generator is controlled to operate intermittently during the heating phase. This allows for the rapid generation of steam, ensuring the taste of the cooked food, while effectively reducing the condensate content in the cooking pot and improving the operational accuracy and stability of the cooking equipment.

[0116] The above provides examples of determining and using the stage control parameters of cooking equipment during the heating phase. Below, we will provide examples of determining and using the stage control parameters of cooking equipment during the temperature maintenance phase.

[0117] In some embodiments, when the temperature range is low, the temperature-maintaining operation component of the cooking device during the temperature-maintaining phase includes a steam generator. S306, based on the temperature-maintaining operation component, the stage control parameters of the cooking device during the temperature-maintaining phase are determined, including: when the temperature range is low, determining a preset temperature-maintaining mode corresponding to the steam generator based on a preset correspondence between the temperature-maintaining operation component and the temperature-maintaining mode; and determining the stage control parameters of the cooking device during the temperature-maintaining phase based on the cooking temperature and the preset temperature-maintaining mode corresponding to the steam generator.

[0118] The preset correspondence between temperature-maintaining operation components and temperature-maintaining methods can be used to characterize the mapping relationship between them. That is, given a specific temperature-maintaining operation component, the corresponding temperature-maintaining method can be determined based on this preset correspondence. The temperature-maintaining method refers to the operating mode of the temperature-maintaining operation component during the temperature-maintaining phase. Understandably, the preset correspondence between temperature-maintaining operation components and temperature-maintaining methods can be pre-defined and generated by the designer.

[0119] Specifically, when the cooking temperature falls within the low-temperature range, it indicates that the user requires a lower cooking temperature. The cooking equipment can heat up quickly during the heating phase to reach or approach the cooking temperature. Even if the steam generator is running throughout the heating phase, the amount of condensate produced is very small, and there is no need to dry the condensate during the temperature maintenance phase. The temperature maintenance phase can utilize a steam generator for more precise temperature control, improving the cooking accuracy during low-temperature cooking, ensuring the taste of the food, and effectively reducing unnecessary energy consumption during operation, thus improving energy efficiency.

[0120] Therefore, when the controller determines that the cooking temperature falls within a low temperature range, it can determine that the temperature maintenance components of the cooking equipment during the temperature maintenance phase include the steam generator. The controller then calls the preset correspondence between the temperature maintenance components and the temperature maintenance mode, and searches for a preset temperature maintenance mode that matches the steam generator from the preset correspondence.

[0121] After determining the preset temperature maintenance mode corresponding to the steam generator, the controller can determine the stage control parameters of the cooking equipment during the temperature maintenance stage based on the cooking temperature and the preset temperature maintenance mode corresponding to the steam generator.

[0122] In some embodiments, the preset temperature maintenance method corresponding to the steam generator is proportional-integral-derivative control (PID control). The controller can determine the control parameters for PID control of the steam generator according to the cooking temperature, so as to maintain the temperature of the cooking pot of the cooking equipment at the cooking temperature during the temperature maintenance stage.

[0123] In the above embodiments, when the temperature range is low, using a steam generator to perform more precise temperature control on the cooking equipment can improve the cooking accuracy of the cooking equipment during low-temperature cooking, ensure the taste of the cooked ingredients, and also effectively reduce unnecessary energy consumption during the operation of the cooking equipment, thereby improving energy utilization efficiency.

[0124] In other embodiments, when the temperature range is medium or high, the temperature-maintaining operation components of the cooking device during the temperature-maintaining phase include a steam generator and a bottom heating element. As shown in Figure 5, S306, based on the temperature-maintaining operation components, the stage control parameters of the cooking device during the temperature-maintaining phase are determined, including steps S502 to S508.

[0125] S502, when the temperature range is medium or high, based on the preset correspondence between the temperature maintenance operation component and the temperature maintenance mode, determine the first preset temperature maintenance mode corresponding to the steam generator and the second preset temperature maintenance mode corresponding to the bottom heating component.

[0126] Specifically, when the temperature range is medium or high, the cooking equipment requires a long heating time to reach the cooking temperature. During the heating phase, a lot of condensation will inevitably be generated in the inner pot. In order to minimize the amount of condensation remaining at the bottom of the inner pot after steaming and reduce the difficulty of cleaning for users, the steam generator and the bottom heating element can be used together during the temperature maintenance phase. The bottom heating element can dry the condensation at the bottom of the inner pot.

[0127] Therefore, when the controller determines that the cooking temperature falls within the high-temperature range, it can determine the first preset temperature maintenance mode corresponding to the steam generator and the second preset temperature maintenance mode corresponding to the bottom heating element based on the preset correspondence between the temperature maintenance operation component and the temperature maintenance mode.

[0128] S504, based on the first preset temperature maintenance mode and cooking temperature, determine the first control parameters of the steam generator during the temperature maintenance stage.

[0129] Specifically, since the first preset temperature maintenance mode is the temperature maintenance mode of the steam generator, the controller can determine the first control parameters of the steam generator during the temperature maintenance stage based on the cooking temperature and the first preset temperature maintenance mode.

[0130] In some embodiments, the first preset temperature control method is PID control, and the controller can determine the first control parameters for PID control of the steam generator based on the cooking temperature.

[0131] S506, based on the second preset temperature maintenance method and cooking mode, determine the second control parameters of the bottom heating element during the temperature maintenance stage.

[0132] Specifically, the second preset temperature maintenance mode is the temperature maintenance mode of the bottom heating element. Under different operating modes, the bottom heating element may have different control methods and control parameters during the temperature maintenance stage. Therefore, the controller can first determine the candidate control parameters of the bottom heating element under the second preset temperature maintenance mode, and then determine the second control parameters of the bottom heating element during the temperature maintenance stage from the candidate control parameters based on the cooking mode.

[0133] In some embodiments, the second preset temperature maintenance mode can be duty cycle control. The controller can determine the duty cycle control parameters of the bottom heating element when using it for temperature maintenance based on the cooking mode.

[0134] In some embodiments, the duty cycle control parameter can be 12:48.

[0135] S508, the first control parameter and the second control parameter are determined as the stage control parameters of the cooking equipment during the temperature maintenance stage.

[0136] Specifically, after obtaining the first control parameter and the second control parameter, the controller can determine the first control parameter and the second control parameter as the stage control parameters of the cooking equipment during the temperature maintenance stage. Subsequently, the controller can control the operation of the steam generator and the bottom heating element according to the first control parameter and the second control parameter respectively, so as to dry the residual condensate at the bottom of the cooking pot while maintaining the cooking temperature of the cooking equipment, effectively reducing the cleaning difficulty for users.

[0137] To reduce overall power consumption and increase steam output during steam cooking, existing built-in steam ovens often use instant steam generators to replace traditional water-boiling steam generators. Figures 6(a) and 6(b) show the structure of an example built-in steam oven using an instant steam generator. The built-in steam oven includes a top heating element / outer tube 601, a bottom heating element 602, an inner cavity 603, a temperature sensor 604, an instant steam generator 605, a solenoid valve 606, an air inlet 607, a water pump 608, a clean water tank 609, a water inlet pipe 610, a water outlet pipe 611, an instant steam temperature sensor 612, a controller 613, a steam inlet pipe 614, an inner cavity air inlet pipe connector 615, a water inlet 616, a water filling pipe 617, a rear fan 618, and a cooling fan 619.

[0138] While existing built-in steam ovens offer advantages such as small size, low cost, low energy consumption, and high steam output, practical use has revealed several drawbacks. First, they typically preheat before activating the instantaneous steam generator 605. This slows down steam generation in the inner cavity 603, negatively impacting the user experience. Second, it can cause food requiring steam cooking to take too long to cook in non-steam environments, affecting its texture. Furthermore, most existing built-in steam ovens rely on a single, preset control logic. Regardless of the user's desired temperature, the instantaneous steam generator 605 continuously operates during the heating and temperature maintenance phases to supply high-temperature steam to the inner cavity 603. This fixed operating logic can also lead to excessive condensation in the inner cavity 603.

[0139] Based on this, in some embodiments, as shown in FIG7, a cooking equipment control method is provided, taking the application of this method to the built-in steam oven shown in FIG6(a) and FIG6(b) as an example for illustration.

[0140] First, the user can set the cooking mode, cooking time, and cooking temperature for the steam oven and click start. The rear fan 618 and cooling fan 619 of the steam oven will start continuously. In this embodiment, the operation of the instant steam generator 605 is as follows: the solenoid valve 606 opens, the water pump 608 draws purified water from the water tank 609, and the water flows through the water inlet pipe 610, solenoid valve 606, water outlet pipe 611, and water pump 608 to the instant steam generator 605. The instant steam temperature sensor 61... 2. Used to detect the temperature of the steam generator. When the instantaneous steam temperature sensor 612 detects that the temperature of the instantaneous steam generator 605 is 165 degrees Celsius, the solenoid valve 606 opens, and the water inlet pump 608 starts working, adding water to the instantaneous steam generator 605. When the instantaneous steam temperature sensor 612 detects that the temperature of the instantaneous steam generator 605 drops to 160 degrees Celsius, the solenoid valve 606 and the water inlet pump 608 stop working, and the instantaneous steam generator 605 continues to heat up to 165 degrees Celsius, thus cycling. The steam generated by the instantaneous steam generator 605 reaches the inner liner cavity 603 through the steam inlet pipe 614 and the inner liner inlet pipe connector 615. The temperature sensor 604 uses a PID algorithm to calculate the core temperature of the inner liner cavity 603 based on the sensed temperature.

[0141] In this embodiment, the built-in steam oven is pre-set with three temperature ranges: 40℃-70℃, 70℃-90℃, and greater than 90℃. The three temperature ranges correspond to three different control logics according to the actual situation of the food being cooked.

[0142] Specifically, when the user-set cooking temperature T falls within the range of 40℃-70℃ (greater than or equal to 40℃ and less than or equal to 70℃), it indicates that the user-set cooking temperature is in the low-temperature range. Within this range, the cooking equipment does not require a long time to reach cooking temperature T. Even if the instantaneous steam generator 605 operates continuously during the heating phase, the amount of condensate it generates is very small. There is no issue of excessive condensate buildup in the inner chamber 603 due to prolonged operation of the instantaneous steam generator 605. During the temperature maintenance phase, there is no need to dry the condensate. Therefore, during the heating phase, the controller 613 will control the top heating element / outer pipe 601 and the instantaneous steam generator 605 to operate simultaneously to achieve rapid steam generation. When the furnace core temperature reaches T-5℃, the temperature maintenance phase begins. The controller 613 will then control the top heating element / outer pipe 601 to stop operating and control the instantaneous steam generator 605 to operate using PID control until the end.

[0143] When the user-set cooking temperature T falls within the range of 70℃-90℃ (i.e., greater than 70℃ but less than or equal to 90℃), it indicates that the user-set cooking temperature is within the medium temperature range. Within this range, the cooking equipment requires a certain heating time to reach the cooking temperature T. During this heating phase, a certain amount of condensate will inevitably be generated within the inner cavity 603. Therefore, during the temperature maintenance phase, it is necessary to consider drying the condensate. Specifically, during the heating phase, similar to the low-temperature range, the controller 613 will control the top heating element / outer tube 601 and the instantaneous steam generator 605 to operate simultaneously. When the core temperature reaches T-5℃, the temperature maintenance stage begins. During this stage, the controller 613 will stop the top heating element / outer tube 601 from working, control the instantaneous steam generator 605 to operate using PID control, and control the bottom heating element 602 to operate using a 12:48 duty cycle until the end. Through the auxiliary heating of the bottom heating element 602, a certain amount of condensate remaining in the inner cavity 603 can be dried, thereby reducing the difficulty for users to clean the inner cavity 603 after cooking.

[0144] When the user-set cooking temperature T falls within a temperature range greater than 90℃, it indicates that the user-set cooking temperature is within the high-temperature range. The cooking equipment requires a longer heating time to reach this temperature. During the heating process, the prolonged operation of the instant steam generator 605 can easily lead to the generation of excessive condensate in the inner cavity 603. Therefore, to reduce the condensate content in the inner cavity 603 during the heating phase, the controller 613 controls the top heating element / outer tube 601 and the instant steam generator 605 to operate simultaneously for 1 minute and 30 seconds, allowing the inner cavity 603 to quickly generate steam. Then, the controller stops the instant steam generator 605 and controls the top heating element / outer tube 601 and the bottom heating element 602 to work together to raise the temperature of the inner cavity 603 to 60℃. By rapidly heating while simultaneously pausing the instant steam generator 605, the condensate content generated in the inner cavity 603 during steaming can be effectively reduced. When the temperature of the inner cavity 603 exceeds 60℃, the controller 613 will shut down the bottom heating element 602 and restart the instant steam generator 605. The top heating element / outer pipe 601 and the instant steam generator 605 will operate simultaneously to continue generating steam. When the furnace core temperature reaches T-5℃, the temperature maintenance stage begins. During this stage, the condensate needs to be dried. Specifically, the controller 613 will stop the top heating element / outer pipe 601, control the instant steam generator 605 using PID control, and control the bottom heating element 602 to operate with a 12:48 duty cycle until the end. While ensuring the cooking effect and the temperature of the inner cavity 603, the bottom heating element 602 can dry the condensate at the bottom of the inner cavity 603 as much as possible after steaming, reducing the difficulty for the user in cleaning the inner cavity 603 after cooking.

[0145] After steaming is complete, the water in the instantaneous steam generator is almost completely vaporized. The solenoid valve 606 can use a valve without an air inlet, and there is very little water in the pipeline. Therefore, one minute before the set working time is reached, the water pump 608 does not need to extract the residual water in the water pipe 611, water supply pipe 617, and instantaneous steam generator 605 as before, so that it is discharged to the bottom of the inner liner cavity 603.

[0146] The cooking equipment control method in this embodiment can effectively solve the problems of slow steam generation in the inner cavity of the original built-in steam oven and excessive condensation in the inner cavity after steaming. It provides an important theoretical basis for the application of instant steam generators in large-capacity built-in steam ovens of 40L-70L.
