Technical Field

[0002] Existing ovens and steam ovens often use smart sensors to determine the size and quantity of food, thereby controlling the heating power to achieve the desired cooking effect. However, the sensitivity of these sensors is easily affected by the environment. For example, kitchen fumes, water vapor, and changes in temperature and humidity can all cause sensor misjudgments or data drift. Furthermore, high-precision sensors are expensive and require regular calibration and maintenance; otherwise, performance degradation can occur, increasing the barrier to entry for use and subsequent maintenance costs.

[0003] Therefore, while sensors have brought convenience to smart cooking, they still face challenges in terms of stability, accuracy, and cost control. Summary of the Invention

Detailed Implementation

[0020] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application 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 the embodiments of this application 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 non-exclusive inclusion; for example, a process, method, system, product, or server 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 devices.

[0022] The following describes an intelligent control method for a cooking device according to this application. The cooking device has a pre-set sidewall equipped with a heat-balancing fan, and a removable food placement partition is provided inside the cooking device to divide the cooking cavity into different layers for cooking food. Figure 1This is a flowchart illustrating an intelligent control method for a cooking device provided in an embodiment of this specification. This specification provides the operational steps of the method described in the embodiment or flowchart, but based on conventional or non-inventive labor, more or fewer operational steps may be included. The order of steps listed in the embodiment is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server products, the method can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment) as shown in the embodiment or drawings. Specifically, as... Figure 1 As shown, the method may include: S1: In response to the start cooking command, control the heat balance fan to start according to preset parameters, and detect the current of the heat balance fan after it starts to obtain the fan current; S2: Search the preset placement layer database according to the fan current to determine the target current range that matches the fan current, and determine the total number of food placement layers in the cooking device according to the target current range to obtain the target placement layer number; the preset placement layer database includes the correspondence between preset current ranges and preset placement layer numbers; S3: Determine the target duty cycle corresponding to the heating device of the cooking equipment based on the target placement layer number; S4: Control the heating device to operate according to the target duty cycle to cook the food at the target number of layers.

[0023] In this embodiment, the cooking device is equipped with a removable food placement partition. This partition divides the cooking cavity into different layers for cooking food. Specifically, at least one removable food placement partition can divide the cooking cavity into one, two, or more layers. Users can place the food to be cooked on one layer, or distribute it across two, three, or more layers according to their actual cooking needs, enabling simultaneous cooking of different quantities of food and improving cooking efficiency.

[0024] For example, if food needs to be placed on a removable food shelf when cooking with a cooking device, different numbers of food layers can be achieved by installing the number of removable food shelves. If food needs to be cooked on the same layer, one removable food shelf can be installed; if food needs to be cooked in two separate layers, two removable food shelves can be installed; if food needs to be cooked in three separate layers, three removable food shelves can be installed, and so on for other layer arrangements.

[0025] For example, if the cooking cavity of the cooking device has a built-in food placement layer, more layers of food can be placed by installing removable food placement partitions. When food needs to be cooked on the same layer, it can be placed directly on the built-in food placement layer within the cooking cavity. When food needs to be cooked in two separate layers, one removable food placement partition can be installed. When food needs to be cooked in three separate layers, two removable food placement partitions can be installed, and so on for other numbers of layers.

[0026] In this embodiment, the cooking device includes a built-in heat balancing fan, which is located on a pre-defined side wall of the cooking cavity. For example, the heat balancing fan is located at the back of the cooking cavity. When food is placed inside the cooking cavity, the number of food layers, as well as the quantity and size of the food, will alter the airflow within the cavity. More food layers result in greater air resistance to the heat balancing fan, leading to a higher fan current. Therefore, the number of food layers inside the cooking cavity can be indirectly determined based on the current magnitude. Specifically, the heat balancing fan is a DC fan, and the cooking device can be an oven, a steam oven, etc.

[0027] In this embodiment, in response to a cooking start command, a heat balance fan is controlled to start according to preset parameters, and the current after the heat balance fan starts is detected to obtain the fan current. The cooking start command includes a target cooking time, a target cooking temperature, and a target cooking mode, and can be triggered on the touchscreen of the cooking device. After obtaining the fan current, a current range matching the fan current is searched in a preset layer number database to determine the target current range. Based on this target current range, the number of food layers in the cooking device is determined to obtain the target layer number. Specifically, the target layer number can be one, two, three, or more layers. For example, if the target layer number is one, it indicates that all food in the cooking cavity is placed on the same layer, meaning the user has placed one layer of food; if the target layer number is two, it indicates that the food in the cooking cavity is distributed across two layers, meaning the user has placed two layers of food.

[0028] In this embodiment, after determining the target number of food placement layers, the duty cycle of the heating device is determined based on the target number of placement layers, resulting in a target duty cycle corresponding to the target number of placement layers. The heating device is then controlled to operate according to the target duty cycle to begin cooking the food in the cooking cavity. A higher duty cycle results in a longer heating device operating time and more heat output; a lower duty cycle results in a shorter heating device operating time and less heat output. Controlling the duty cycle of the heating device allows for precise control of its output power, achieving energy savings and avoiding unnecessary energy waste. It also prevents the heating device from operating at high power for extended periods, reducing wear and tear and extending its lifespan. Specifically, the heating device can be a heating element.

[0029] In one exemplary embodiment, such as Figure 2 As shown, the method for constructing the preset placement layer database may include: S021: When cooking the food using a preset cooking device, and the number of food placement layers is the preset number of placement layers, control the preset cooking device to heat multiple preset quantities of the food; the preset number of placement layers is based on the number of removable food placement partitions installed, the number of preset placement layers is at least two, and multiple preset quantities of the food are placed under each preset placement layer; S022: Obtain the current of the heat balance fan for each of the preset quantities to obtain multiple preset currents; S023: Determine the preset current range corresponding to the preset number of placement layers based on the multiple preset currents corresponding to the preset number of placement layers; S024: Construct the preset placement layer database based on the correspondence between the preset placement layer number and the preset current range.

[0030] In this embodiment, to more quickly and accurately determine the number of food layers in the cooking cavity based on the fan current, a preset layer database can be constructed based on the correspondence between preset layer numbers and preset current ranges, thereby improving the intelligent control efficiency of the cooking equipment. Using a preset cooking device to cook food, and knowing the actual number of food layers, multiple preset quantities of food are heated. By acquiring the current of the heat balance fan for each preset quantity, multiple preset currents corresponding to the preset layer number are obtained, thus determining the preset current range corresponding to that preset layer number. Performing the above operation for each preset layer number yields multiple preset layer numbers and their corresponding preset current ranges, constructing a preset layer database. The preset layer number can be one, two, three, or more layers, with different preset quantities of food and different sizes placed under each preset layer number to ensure the comprehensiveness and reliability of the current collection data. The number of layers can be determined based on removable food placement partitions within the cooking equipment. The more removable food placement partitions installed in the cooking cavity, the more food layers there are.

[0031] For example, when cooking food using preset cooking equipment, if the preset number of layers is one, the current of the heat balancing fan is obtained for each preset quantity, resulting in multiple heat balancing fan current values, thereby determining the current range corresponding to one layer. If the preset number of layers is two, the current of the heat balancing fan is obtained for each preset quantity, resulting in multiple heat balancing fan current values, thereby determining the current range corresponding to two layers. If the preset number of layers is three, the current of the heat balancing fan is obtained for each preset quantity, resulting in multiple heat balancing fan current values, thereby determining the current range corresponding to three layers. The method for obtaining the current range corresponding to other numbers of layers can be deduced similarly.

[0032] This application embodiment obtains the correspondence between the preset number of placement layers and the preset current range, and pre-builds a database of preset placement layers. This enables the determination of the number of food placement layers in the cooking cavity more quickly and accurately based on the fan current, thereby improving the cooking accuracy and efficiency of the cooking equipment and achieving more precise intelligent control of the cooking equipment.

[0033] In one exemplary embodiment, such as Figure 3 As shown, determining the preset current range corresponding to the preset placement layer number based on the multiple preset currents corresponding to the preset placement layer number may include: S0231: Determine the initial current range corresponding to each preset placement layer number based on the multiple preset currents corresponding to each preset placement layer number; S0232: Group the multiple preset placement layers, take two preset placement layers that differ by one layer as a group, and determine the current critical value between the two initial current intervals according to the two initial current intervals in each group, and determine the current critical value as a preset current threshold. S0233: Determine the preset current range corresponding to the preset number of placement layers based on the preset current threshold.

[0034] In this embodiment of the application, during the process of constructing the database of preset placement layers, for multiple preset currents under each preset placement layer, the corresponding initial current range can be determined first. Since the number of placement layers can be one, two, three, or more layers, the two initial current ranges corresponding to two preset placement layers that differ by one layer may be non-overlapping current ranges. To ensure the overall reliability of practical applications, the two non-overlapping current ranges can be expanded into continuous current ranges. For example, multiple preset placement layers can be grouped, with two preset placement layers that differ by one layer forming a group. Based on the two initial current ranges in each group, a current threshold value between these two initial current ranges is determined, and this current threshold value is defined as a preset current threshold. Then, based on the obtained preset current threshold value, the preset current range corresponding to each preset placement layer is determined.

[0035] For example, taking the existence of two preset placement layers (one or two layers), if the preset placement layer is one layer, the initial current range is M1-M2 amperes; if the preset placement layer is two layers, the initial current range is M3-M4 amperes, where M1 is less than M2, M2 is less than M3, and M3 is less than M4. Based on these two initial current ranges, M2-M3 can be used as a current threshold, i.e., a current value within the range M2-M3. If the preset current threshold is represented by M5, and M2 < M5 < M3, then the preset current range for one layer is 0-M5 amperes, and the preset current range for two layers is a current range greater than M5. When there are more preset placement layers, the method for determining the preset current range can be deduced similarly. Specifically, taking one and two preset placement layers as examples, if the initial current range corresponding to one preset placement layer is 0.1 A-0.2 A, and the initial current range corresponding to two preset placement layers is 0.3 A-0.4 A, based on these two ranges, the preset current threshold can be determined to be 0.25 A. Therefore, the preset current range corresponding to one preset placement layer is 0 A-0.25 A, and the preset current range corresponding to two preset placement layers is a current range greater than 0.25 A. It should be noted that the above specific current values ​​are for illustrative purposes only and do not represent the current values ​​and ranges used in actual implementation.

[0036] This application embodiment determines the corresponding preset current threshold by using two initial current intervals corresponding to two preset placement layer numbers that differ by one layer. This can optimize the division of preset current intervals, making it suitable for different application scenarios and improving the applicability of intelligent control methods.

[0037] In an exemplary embodiment, the preset number of placement layers includes a first preset number of placement layers, a second preset number of placement layers, and a third preset number of placement layers; the preset current threshold includes a first preset current threshold and a second preset current threshold; and determining the preset current range corresponding to each preset number of placement layers based on the preset current threshold may include: Based on the first preset current threshold, the current range corresponding to the first preset number of placement layers is determined as the first preset current range; the first preset current range is a range that is less than or equal to the first preset current threshold. Determine that the current range corresponding to the second preset placement layer is the second preset current range according to the first preset current threshold and the second preset current threshold; the first preset current threshold is less than the second preset current threshold; the second preset current range is a range greater than the first preset current threshold and less than the second preset current threshold; Determine that the current range corresponding to the third preset placement layer is the third preset current range according to the second preset current threshold; the third preset current range is a range greater than or equal to the second preset current threshold; Wherein, the first preset placement layer is less than the second preset placement layer, and the second preset placement layer is less than the third preset placement layer.

[0038] In the embodiment of the present application, if the maximum number of placement layers of the cooking device is three, the preset placement layers may include a first preset placement layer, a second preset placement layer, and a third preset placement layer, which respectively represent that the placement layer is one layer, two layers, and three layers. The above preset current thresholds may include a first preset current threshold and a second preset current threshold, wherein the first preset current threshold is less than the second preset current threshold, and thus the current range corresponding to each preset placement layer can be obtained.

[0039] In the embodiment of the present application, the more the number of placement layers of the food in the cooking cavity, the greater the current of the thermal balance fan. According to the above first preset current threshold, the first preset placement layer can be determined, that is, the current range corresponding to when the food placement layer is one layer is the first preset current range; according to the above first preset current threshold and the second preset current threshold, the second preset placement layer is determined, that is, the current range corresponding to when the food placement layer is two layers is the second preset current range; according to the above second preset current threshold, the third preset placement layer is determined, that is, the current range corresponding to when the food placement layer is three layers is the third preset current range. Exemplarily, let I1 represent the above first preset current threshold and I2 represent the above second preset current threshold. The above first preset current range is the range of ≤I1, the above second preset current range is the range between I1 and I2, and the above third preset current range is the range of ≥I2. When there are more preset placement layers, the determination method of the preset current range can be analogized accordingly.

[0040] Specifically, if the detected fan current after the thermal balance fan is started is I, if I≤I1, determine that the food placement layer in the cooking cavity is the first preset placement layer, that is, one layer; if I1<I<I2, determine that the food placement layer in the cooking cavity is the second preset placement layer, that is, two layers; if I≥I2, determine that the food placement layer in the cooking cavity is the third preset placement layer, that is, three layers.

[0041] This application embodiment sets a preset current threshold to more accurately divide the current range corresponding to different placement layers, thereby constructing a database of placement layers with a wider range of applications and improving the applicability of the intelligent control method for cooking equipment.

[0042] In one exemplary embodiment, such as Figure 4 As shown, determining the target duty cycle corresponding to the heating device of the cooking equipment based on the target placement layer number includes: S31: Obtain a preset duty cycle database; the preset duty cycle database includes the correspondence between the preset placement layer number and the preset duty cycle; the preset placement layer number and the preset duty cycle are positively correlated; S32: Search the preset duty cycle database according to the target placement layer number to determine the target duty cycle corresponding to the target placement layer number.

[0043] In this embodiment, after determining the specific number of food layers inside the cooking cavity, the corresponding target duty cycle can be quickly determined by searching a preset duty cycle database, thereby controlling the heating equipment to operate according to the target duty cycle, thus improving the cooking accuracy and efficiency of the cooking equipment.

[0044] In this embodiment, the preset number of food layers is positively correlated with the preset duty cycle. A higher number of food layers indicates a larger quantity of food. To ensure these quantities cook within the same cooking time, guaranteeing the cooking effect and improving the cooking efficiency of the cooking equipment, the heating device can be controlled to cook the food at a larger duty cycle. For example, if the cooking equipment can be set to hold three layers of food, the target duty cycle for the heating device is the first preset duty cycle when there is one layer; the target duty cycle for the heating device is the second preset duty cycle when there are two layers; and the target duty cycle for the heating device is the third preset duty cycle when there are three layers. The first preset duty cycle is smaller than the second preset duty cycle, and the second preset duty cycle is smaller than the third preset duty cycle.

[0045] Specifically, the first preset duty cycle can be set to 60%, the second preset duty cycle can be set to 80%, and the third preset duty cycle can be set to 100%. In addition, the preset duty cycle can also be other numerical ratios, and this application does not limit the specific value of the preset duty cycle.

[0046] This application embodiment can quickly and accurately determine the target working duty cycle of the heating device by searching a preset duty cycle database, ensuring the cooking effect of food and improving the cooking efficiency of the cooking device.

[0047] In one exemplary embodiment, such as Figure 5 As shown, the step of obtaining the preset duty cycle database may include: S311: When cooking the food using a preset cooking device and the number of layers of the food is the preset number of layers, control the heating device of the preset cooking device to heat the food with an initial duty cycle; S312: Monitor the cumulative cooking time of the food in real time, and obtain the current temperature of the cooking cavity when the cumulative cooking time reaches the preset cooking time; S313: Compare the current temperature with the preset cooking temperature. If the current temperature is lower than the preset cooking temperature, adjust the initial duty cycle and control the heating device to heat the food according to the adjusted duty cycle. S314: When the temperature of the cooking cavity is detected to have reached the preset cooking temperature, the adjusted duty cycle is used as the preset duty cycle; S315: Based on the correspondence between the preset placement layer number and the preset duty cycle, obtain the preset duty cycle database.

[0048] In this embodiment, to more quickly and accurately determine the target duty cycle of the heating device based on the target number of food layers, a preset duty cycle database can be constructed by obtaining the correspondence between preset food layers and preset duty cycles, thereby achieving intelligent control of the cooking equipment. Controlling the heating duty cycle based on the number of food layers allows for precise control of the heating device's output power, achieving green energy saving and avoiding unnecessary energy waste. Furthermore, if the number of food layers is small, the operating duty cycle of the heating device can be reduced accordingly, preventing the heating device from operating at high power for extended periods, reducing wear and tear, and extending the device's lifespan.

[0049] In this embodiment, a preset cooking device is used to cook the food. Knowing the actual number of layers of food, the heating device is first controlled to heat the food according to an initial duty cycle, and the cumulative cooking time is monitored in real time. When the cumulative cooking time reaches the preset cooking time, the current temperature of the cooking cavity is obtained and compared with the preset cooking temperature. If the current temperature is lower than the preset cooking temperature, it indicates that the initial duty cycle is too small, and the duty cycle of the heating device needs to be increased to avoid excessively low heating temperatures and ensure the cooking effect of the food. Therefore, the initial duty cycle can be adjusted based on the current temperature and the preset cooking temperature to ensure the adjusted duty cycle. The system ensures the cooking cavity reaches the preset cooking temperature, and the adjusted duty cycle is used as the preset duty cycle. If the current temperature is higher than the preset cooking temperature, it indicates the initial duty cycle is too large, requiring a reduction in the heating device's duty cycle to prevent excessive heating and ensure optimal food cooking results. Therefore, the initial duty cycle can be adjusted based on the current temperature and the preset cooking temperature to ensure the adjusted duty cycle reaches the preset cooking temperature, and this adjusted duty cycle is used as the preset duty cycle. If the current temperature equals the preset cooking temperature, it indicates the initial duty cycle is appropriate, and good food cooking results can be achieved at this initial duty cycle; this initial duty cycle can then be designated as the preset duty cycle. By performing the above operation on foods with different placement layers, the preset duty cycle corresponding to each preset placement layer can be obtained, thus constructing the aforementioned preset duty cycle database.

[0050] This application embodiment obtains the correspondence between the preset number of food layers and the preset duty cycle, and pre-builds a preset duty cycle database. This enables the target duty cycle of the heating equipment to be determined more quickly and accurately based on the actual number of food layers. In addition, by controlling the duty cycle of the heating equipment according to the actual number of food layers, unnecessary energy waste can be avoided, achieving green and energy-saving practices. This improves the cooking accuracy and efficiency of the cooking equipment, while also preventing the heating equipment from operating at high power for extended periods, reducing equipment wear and tear, and extending the equipment's lifespan.

[0051] In one exemplary embodiment, such as Figure 6 As shown, the cooking start command includes a target cooking temperature, and controlling the heating device to operate according to the target duty cycle to cook the food at the target number of layers can include: S41: Control the heating device to operate according to the target duty cycle, cook the food at the target number of layers, and monitor the cumulative heating time of the cooking cavity in real time during the cooking process; S42: When the cumulative heating time is detected to have reached the preset heating time, the current heating temperature of the cooking cavity is obtained; S43: Compare the current heating temperature with the target cooking temperature. If the current heating temperature is lower than the target cooking temperature, adjust the target duty cycle according to the current heating temperature and the target cooking temperature to obtain the adjusted duty cycle. S44: Control the heating device to operate according to the adjusted duty cycle and continue cooking the food.

[0052] In this embodiment, the heating device of the cooking equipment operates according to a target duty cycle determined based on the number of food layers, starting to cook the food inside the cavity. The cumulative heating time of the cooking cavity is monitored in real time throughout the cooking process. When the cumulative heating time reaches a preset heating time, the current heating temperature of the cooking cavity is obtained and compared with the target cooking temperature carried in the cooking start command. If the current heating temperature is lower than the target cooking temperature, it indicates that the current operating duty cycle of the cooking equipment is too small to cook the food at the target cooking temperature. The duty cycle of the heating device needs to be increased to avoid the heating temperature being too low and affecting the cooking effect. Therefore, the target duty cycle can be adjusted according to the current heating temperature and the target cooking temperature, and the heating device is controlled to operate according to the adjusted duty cycle to continue cooking the food and continuously monitor the temperature of the cavity. Monitoring is performed. If the current heating temperature is higher than the target cooking temperature, it indicates that the current duty cycle of the cooking equipment is too high, which may cause the food to be overcooked and affect its taste. Therefore, it is necessary to reduce the duty cycle of the heating equipment. The target duty cycle can be adjusted according to the current heating temperature and the target cooking temperature, and the heating equipment should be controlled to operate according to the adjusted duty cycle to continue cooking the food, while continuously monitoring the temperature of the cavity. If the current heating temperature is equal to the target cooking temperature, it indicates that the target duty cycle is appropriate. The food should continue to be cooked according to the target duty cycle, and the temperature of the cavity should be continuously monitored. If the temperature of the cavity is detected to be too high or too low, the operating duty cycle of the heating equipment should be adjusted in a timely manner according to the above method to ensure that the food is cooked according to the target cooking temperature, guarantee the cooking effect, realize real-time control of the cooking equipment, and improve the level of intelligent cooking.

[0053] In this embodiment of the application, the heating device of the cooking equipment may include multiple heating devices, such as a top heating device, a bottom heating device, and a back heating device. Therefore, in addition to controlling the duty cycle of the heating device according to the actual number of food layers placed in the cooking cavity, different heating devices can be turned on or off according to the number of food layers placed. By reasonably planning the working scenarios of different heating devices, it is possible to effectively avoid the same heating device working at high power for a long time, reduce the wear and tear of the device, and extend the service life of the device.

[0054] For example, if the cooking equipment can be placed in a maximum of three layers, the preset number of layers can include a first preset number of layers, a second preset number of layers, and a third preset number of layers, representing one, two, and three layers respectively. The above method can include: If the target placement layer is determined to be the first preset layer, the top heating device is turned on to cook the food; If the target placement layer is determined to be the second preset layer, the top heating device and the back heating device are turned on to cook the food; With the target placement layer set to the third preset layer, the top heating device, back heating device, and bottom heating device are turned on to cook the food.

[0055] In this embodiment, when the actual number of food layers in the cooking cavity is determined to be a first preset number, i.e., one layer, only the top heating device can be turned on to cook the food; when the actual number of food layers in the cooking cavity is determined to be a second preset number, i.e., two layers, both the top heating device and the back heating device can be turned on to cook the food; when the actual number of food layers in the cooking cavity is determined to be a third preset number, i.e., three layers, the top heating device, the back heating device, and the bottom heating device can be turned on to cook the food, ensuring the cooking effect of the food, ensuring that different quantities of food can achieve the same cooking effect, and improving the cooking accuracy and cooking efficiency of the cooking equipment.

[0056] This application embodiment monitors the temperature of the cooking cavity in real time during the cooking process. If the temperature is too high or too low, the duty cycle of the heating device is adjusted in a timely manner according to the temperature of the cavity, thereby realizing real-time control of the cooking process, ensuring the cooking effect of the food and the cooking efficiency of the cooking equipment, and improving the intelligent control level of the cooking equipment.

[0057] This application embodiment can determine the number of food layers in the cooking cavity by detecting the current of the heat balance fan built into the cooking equipment. Based on the actual number of food layers, the heating device of the cooking equipment is controlled to operate at the corresponding duty cycle, achieving intelligent control of the cooking equipment. By pre-building a preset layer database, the number of food layers in the cooking cavity can be determined more quickly and accurately based on the fan current, improving the cooking precision and efficiency of the cooking equipment and achieving more precise intelligent control. By determining the corresponding duty cycle of the heating device based on different food layers, the output power of the heating device can be controlled, avoiding unnecessary energy waste. While achieving green energy saving, it also avoids the heating device from operating at high power for extended periods, reducing equipment wear and extending its service life.
