[0069] In order to make the above objectives, characteristics and advantages of the present application more apparent, further specific embodiments will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] In the conventional cooking equipment, the distance between the heating tube and the food material is fixed, and the fixed position of the heating tube may cause uneven heating due to different shapes, sizes or positions of the food material, affecting the cooking effect.

[0071] One of the core ideas of the embodiments of the present application is to adjust the distance between the heating device and the cooking food material according to the first heat generated by the heating device radiating to the cooking food material and reaching the mature state of the cooking food material and the second heat required to be absorbed by the cooking food material to reach the mature state, so as to avoid local overheating or insufficient heating, and make the food material more evenly heated.

[0072] Referring to Figure 1 , a step flow chart of a control method of a cooking equipment provided by the embodiments of the present application is shown, the cooking equipment comprising a heating chamber, heating devices respectively arranged at the top and bottom of the heating chamber, and a lifting mechanism connected with the heating devices; the method can specifically comprise the following steps:

[0073] Step 101, obtaining a set cooking temperature and an initial distance of the heating device relative to the cooking food material;

[0074] In this embodiment, the cooking equipment is taken as an example of a baking function steam oven, and the principle of the present application is described exemplarily, however, this description is only exemplary, the scope of the present application is not limited thereto, and the principle of the present application can also be applied to other cooking equipment with baking function.

[0075] The heating chamber refers to a closed or semi-closed space in the cooking equipment for containing food and directly heating, which is the core working area of the oven, steam oven, microwave oven and other equipment.

[0076] The heating device is a core component in the cooking equipment for generating heat energy, which is converted from electric energy, gas or other energy into heat and directly acts on the food.

[0077] The lifting mechanism comprises a driving motor, a gear and a rotating belt, the lifting mechanism drives the gear to work through the driving motor, the two gears are mutually engaged, so the rotating directions are necessarily opposite, when the upper gear rotates counterclockwise, the upper rotating belt moves clockwise to realize the upward movement of the top heating device, and the lower rotating belt moves counterclockwise to realize the downward movement of the bottom heating device.

[0078] The cooking device has a steaming and baking function. When a user selects a steaming mode, the user can select a cooking steam amount according to a cooking food category. For food with a short cooking time and easy ripening, a low steam mode can be selected to reduce the generation of condensed water. In addition, there are medium and high steam modes, which can be suitable for food with relatively easy ripening and relatively difficult ripening, respectively, to shorten the cooking time, retain the nutrition and taste of the food, and determine the steam amount of the low, medium and high modes by the vaporization rate R of water vapor.

[0079] The recommended steam mode for different food materials is displayed on the control panel, that is, the user is recommended to use the low steam mode in the fermentation and thawing auxiliary cooking scene, and the user is recommended to use the high steam mode in the steamed bun cooking scene, which can be selected by the user.

[0080] When the user selects the baking mode, the user first selects the recommended temperature T (℃) of the food category to be cooked, selects the cooking time t (min) according to the user's own needs, and selects the recommended temperature to obtain the cooking temperature of the food to be cooked.

[0081] The initial distance of the heating device relative to the cooking food is the vertical distance between the heating device and the cooking food at the beginning of cooking. An infrared sensor is installed at the top of the heating cavity to detect the distance between the heating device and the cooking food. The top and bottom heating devices are lifted at the same time, so the distance between the food and the top and bottom heating devices is the same.

[0082] In this embodiment, the distance between the heating device and the food is detected by the infrared sensor to obtain the initial distance of the heating device relative to the cooking food.

[0083] Referring to Figure 2 , a cooking device structure schematic diagram of a control method of a cooking device provided by an embodiment of the present application is shown, Figure 2 The overall structure of the cooking device 20 is shown, which includes a heating cavity 201, heating devices 202 arranged at the top and bottom of the heating cavity respectively, and a lifting mechanism (not shown in the figure) connected with the heating devices 202 and located at the top and bottom of the heating cavity 201 respectively.

[0084] In step 102, according to the cooking temperature and the initial distance, a first heat generated by the heating device radiated to the cooking food and making the cooking food reach a ripening state is determined;

[0085] The radiant heat of the heating device refers to the way that the heating tube in the cooking equipment directly transmits heat to food or the surrounding environment through electromagnetic waves (mainly infrared waves), which belongs to non-contact heat transfer. Its efficiency depends on the heating body temperature, surface characteristics and radiation distance.

[0086] In this embodiment, based on the obtained cooking temperature and initial distance, the heat radiated by the heating tube to the food material at the set temperature and initial distance is calculated by the Stefan-Boltzmann law.

[0087] In some embodiments, the step 102 can include the following sub-steps:

[0088] Sub-step S11, obtaining the heated area of the cooking food material, target heating time, heat absorption rate of the cooking food material, heating parameter of the heating device;

[0089] The heated area refers to the effective heat exchange area of the cooking food material directly or indirectly contacting the heat source during the cooking process, which is determined based on the size of the cooking food material.

[0090] The target heating time refers to the time required for the cooking food material to reach the target core temperature (or specified doneness) from the initial temperature under specific cooking conditions.

[0091] The heat absorption rate refers to the ratio of the heat energy absorbed by the cooking food material per unit time to the total input heat energy, reflecting the energy conversion efficiency, and different types of food materials correspond to different heat absorption rates.

[0092] The heating parameter of the heating device includes the emissivity of the heating device material and the Stefan-Boltzmann constant. The emissivity is a dimensionless parameter of the surface radiation heat capacity of the material, defined as the ratio of the actual radiation energy to the ideal black body radiation energy at the same temperature, which directly affects the radiation heat transfer efficiency of the heating element in the cooking equipment. The Stefan-Boltzmann constant (σ) is a physical constant in thermodynamics that describes the relationship between the total power of a black body and temperature, its value and unit are: σ = 5.670374419 × 10 -8 Wm -2 K -4 , which physically represents the total energy (radiation exitance) radiated per unit time by an ideal black body per unit area at absolute temperature T.

[0093] In this embodiment, in order to determine the first heat generated by the heating device radiating to the cooking food material and making the cooking food material reach the mature state, the heated area of the cooking food material, the target heating time, the heat absorption rate of the food material, and the emissivity and Stefan-Boltzmann constant of the heating device material need to be obtained.

[0094] In some embodiments, the top of the heating cavity of the cooking equipment is provided with an image detection device, and the step S11 can include the following sub-steps:

[0095] Sub-step S111, acquiring an image of the cooking food material by the image detection device;

[0096] Sub-step S112, determining a heated area of the cooking food material according to the acquired image of the cooking food material.

[0097] The image detection device is an intelligent system for realizing cooking state monitoring by capturing visual information of the food material in the cooking process in real time through an optical sensor (such as a CCD / CMOS) and analyzing color, shape, texture and other features by using an image processing algorithm. The image detection device can be a depth camera, an optical sensor and the like, and the embodiments of the present application are not limited thereto.

[0098] The image detection device is arranged at the top of the heating cavity of the cooking device, and three-dimensional point cloud data of the food is acquired by three-dimensional point grabbing of the food.

[0099] In the embodiment, real-time images of the food material are acquired by the built-in image detection device (such as a depth camera), and the heated area of the food material is accurately calculated based on three-dimensional point cloud data processing technology, and the parameter is used as a key input for subsequent heat radiation calculation. The heated area input by artificial or fixed parameter assumption does not conform to the actual situation (such as the food material is not placed in the center or the shape is irregular), and the real heated area is directly measured by the image, so as to avoid estimation error and make the heat calculation more accurate.

[0100] Referring to Figure 3 , a schematic diagram of an image detection device of a control method of a cooking device provided by an embodiment of the present application is shown, Figure 3 which shows a schematic diagram of three-dimensional point grabbing of the food by the image detection device 203, the image detection device 203 is arranged at the top position inside the cooking device, and the heated area of the food material in the cooking device can be accurately calculated based on three-dimensional point cloud data processing technology.

[0101] In some embodiments, the step S11 can include the following sub-steps:

[0102] Sub-step S121, acquiring an initial heating time;

[0103] Sub-step S122, if the initial heating time is within a preset time threshold range, determining the initial heating time as a target heating time;

[0104] Sub-step S123, if the initial heating time is not within the preset time threshold range, adjusting the initial heating time so that the adjusted heating time is within the preset time threshold range, and determining the adjusted heating time as the target heating time.

[0105] In the embodiment, when the user selects the roasting mode, the user first selects the recommended temperature for cooking the food of the category. After the user selection, the first heat generated by the heating device radiating to the cooking food and making the cooking food reach the mature state at the recommended temperature is obtained. The initial heating time is determined based on the first heat generated by the heating device radiating to the cooking food and making the cooking food reach the mature state and the second heat required to be absorbed by the cooking food to reach the mature state.

[0106] Different kinds of cooking food correspond to different preset time ranges. The threshold values of the cooking time of each kind of food are t1 and t2. A determination is made according to the obtained initial heating time, that is, whether t1≤t≤t2 is satisfied. If the initial heating time is within the preset time threshold range, the cooking time does not need to be adjusted, and the initial heating time is determined as the target heating time. If the initial heating time is not within the preset time threshold range, the user is reminded to increase or decrease the cooking time, so that the adjusted heating time is within the preset time threshold range, to ensure that the food is mature without being burnt under the cooking time length. The adjusted heating time is determined as the target heating time.

[0107] The initial heating time is intelligently checked and adjusted by the preset time threshold range, to ensure that the heating time is always within a safe and reasonable range, and to avoid the problem of overcooked or undercooked food caused by improper time setting.

[0108] In substep S12, the first heat generated by the heating device radiating to the cooking food and making the cooking food reach the mature state is determined according to the cooking temperature, the heated area, the target heating time, the initial distance, the heat absorption rate, and the heating parameter.

[0109] In the embodiment, the first heat generated by the heating device radiating to the cooking food and making the cooking food reach the mature state is calculated based on the obtained heated area, target heating time, cooking temperature, initial distance, food heat absorption rate, heating tube emissivity, and Stefan-Boltzmann constant, by the following formula:

[0110] Q=(αεσT 4 At) / 4πr 2

[0111] Q is the first heat generated by the heating device radiating to the cooking food and making the cooking food reach the mature state; α is the heat absorption rate of the cooking food, which is strongly related to the type of food; ε is the emissivity of the heating device material; σ is the Stefan-Boltzmann constant; T is the cooking temperature; A is the heated area of the cooking food; t is the target heating time; and r is the initial distance. By introducing the heated area and the heat absorption rate, the heating deviation problem caused by ignoring the physical properties of the food in the traditional method is solved.

[0112] Step 103, obtaining the second heat absorbed by the cooking food to reach the mature state;

[0113] The second heat refers to the additional heat absorbed by the cooking food from the initial heating stage (such as surface thawing / preheating) to the core maturation stage.

[0114] In this embodiment, the second heat absorbed for maturation is calculated by the mass of the food, the specific heat capacity, and the temperature change, wherein the mass is obtained by the weighing module, the specific heat capacity is automatically matched with the database recommended value based on the food type, and the temperature change is determined by the difference between the initial temperature and the cooking target temperature.

[0115] In some embodiments, the step 103 can include the following sub-steps:

[0116] Sub-step S21, obtaining the mass of the cooking food, the initial temperature of the cooking food, the target temperature of the cooking food to reach maturity, and the specific heat capacity of the cooking food;

[0117] In this embodiment, the weighing module and the infrared sensor are provided in the cooking device, the mass of the cooking food can be obtained by the weighing module, the initial temperature of the cooking food can be measured by the infrared sensor, the target temperature of the cooking food to reach maturity is obtained according to the food type, and the specific heat capacity of the cooking food is matched based on the food type.

[0118] Sub-step S22, determining the second heat absorbed by the cooking food to reach the mature state according to the mass, the initial temperature, the target temperature, and the specific heat capacity.

[0119] In this embodiment, the temperature change value of the cooking food is determined by the initial temperature of the cooking food and the target temperature of the cooking food to reach maturity. Based on the mass of the cooking food, the temperature change value of the cooking food, and the specific heat capacity, the second heat absorbed by the cooking food to reach the mature state is determined by the following formula:

[0120] Q' = mcΔT

[0121] Q' is the second heat absorbed by the cooking food to reach the mature state; m is the mass of the cooking food; c is the specific heat capacity of the cooking food; and ΔT is the temperature change value of the cooking food. By using the key thermodynamic parameters such as the mass, the initial temperature, the target temperature, and the specific heat capacity of the food, the calculation of the heat requirement is more accurate, and it can adapt to the heat requirement of different foods.

[0122] Step 105, determining whether the first heat and the second heat match;

[0123] In the present embodiment, the matching determination is made by comparing the first heat Q (heat radiated by the heat generating device) with the second heat Q' (heat required for the food material to mature) in combination with the heat loss correction factor λ, to determine whether the first heat is equal to the product of the second heat and the correction factor, thereby determining whether the first heat and the second heat match.

[0124] In some embodiments, the step 104 can include the following sub-steps:

[0125] Sub-step S31, determining whether the first heat is equal to the product of the second heat and the correction factor; if the first heat is equal to the product of the second heat and the correction factor, it is determined that the first heat and the second heat match; if the first heat is not equal to the product of the second heat and the correction factor, it is determined that the first heat and the second heat do not match.

[0126] In the present embodiment, the determination is made by whether the first heat is equal to the product of the second heat and the correction factor, and when the first heat is equal to the product of the second heat and the correction factor, it is determined that the heat supply and demand are balanced, and the optimal cooking state of the food material is met; when the first heat is not equal to the product of the second heat and the correction factor, it is determined that the first heat and the second heat do not match. The heat supply and demand of the first heat and the second heat are dynamically balanced, avoiding the continuous excessive heating or insufficient heating caused by fixed parameters in traditional equipment, thereby dynamically optimizing the distance between the heat generating device and the cooking food material without manual operation by the user.

[0127] Step 105, if the first heat and the second heat do not match, controlling the lifting mechanism to drive the heat generating device to approach or move away from the cooking food material, so that the first heat and the second heat match.

[0128] In the present embodiment, when it is detected that the first heat does not match the second heat calibrated by the correction factor, the vertical distance between the heat generating device and the food material is dynamically adjusted by the lifting mechanism until the first heat calculated in real time is equal to the product of the second heat and the correction factor, realizing closed-loop control of heat balance. The process realizes synchronous and precise displacement of the upper and lower heat generating devices through the gear linkage system, ensuring cooking efficiency.

[0129] In some embodiments, the step 105 can include the following sub-steps:

[0130] Sub-step S41, if the first heat is greater than the product of the second heat and the correction factor, controlling the lifting mechanism to drive the heat generating device to move away from the cooking food material; if the first heat is less than the product of the second heat and the correction factor, controlling the lifting mechanism to drive the heat generating device to approach the cooking food material.

[0131] In the present embodiment, the heating distance is dynamically adjusted when it is detected that the first heat does not match the second heat calibrated by the correction coefficient: when the first heat is greater than the product of the second heat and the correction coefficient, the lifting mechanism is controlled to move the heat generating device away from the food to reduce the heat radiation intensity; when the first heat is less than the product of the second heat and the correction coefficient, the heating distance is shortened to enhance heat transfer, and through this closed-loop feedback mechanism, the first heat is always matched with the second heat calibrated by the correction coefficient, thereby accurately controlling the cooking process and ensuring that the food maturity reaches the optimal state.

[0132] By dynamically adjusting the distance between the heat generating device and the food, the heat is accurately matched: when the first heat is greater than the requirement, the distance is increased to prevent overcooking; when the first heat is insufficient, the distance is shortened to enhance heating, thereby ensuring that the food is evenly heated and the energy efficiency is optimal, avoiding the problems of uneven heating or energy waste in the traditional fixed distance mode, improving the cooking success rate, and reducing the user's operation difficulty through automatic adjustment. It is suitable for various food and cooking scenes.

[0133] In some embodiments, the lifting mechanism includes a driving motor, a gear, and a rotating belt; the driving motor is connected to the rotating belt through the gear; the rotating belt is connected to the heat generating device; and the step 105 can include the following sub-steps:

[0134] Sub-step S51, control the driving motor to operate to drive the gear and the rotating belt to rotate to control the heat generating device to move up and down to make the heat generating device approach or move away from the cooking food.

[0135] The lifting mechanism is the core module for realizing the vertical up-and-down movement of the heat generating device in the cooking equipment, and its structure includes a driving motor for providing power, a gear set, and a rotating belt. The driving motor drives the gear to work, and the two gears are engaged with each other, so the rotating directions are necessarily opposite. When the upper gear rotates counterclockwise, it drives the upper rotating belt to move clockwise, realizing the upward movement of the top heating tube plane, and at the same time, the lower rotating belt moves counterclockwise, realizing the downward movement of the bottom heating tube plane, thereby realizing the movement of the two heating tube planes away from the food.

[0136] In the present embodiment, the driving motor is operated in real time by controlling the lifting mechanism to accurately drive the gear set and the linkage rotating belt to work, thereby controlling the lifting movement of the heat generating device: when the heat radiation needs to be enhanced, the heat generating device is driven to approach the food, and when the heat radiation needs to be weakened, the heat generating device is driven to move away from the food. Through this closed-loop adjustment of mechatronics, the heat generating device is always dynamically maintained at the optimal heating distance, the actual radiation heat is continuously matched with the heat required by the food, and finally the cooking effect is accurately controlled. The entire lifting process is real-time feedback of position data by high-precision sensors, ensuring the rapidity and stability of the adjustment.

[0137] The lifting mechanism composed of a driving motor, gears and rotating belts realizes the precise lifting control of the heating device, meets the requirements of different food materials on the heating distance, and the rotating belt structure makes the heating device more flexible in lifting in the heating cavity, without manual intervention, which improves the cooking effect and enhances the use safety.

[0138] Referring to Figure 4 , a lifting mechanism structure schematic diagram of a control method of a cooking equipment provided by an embodiment of the present application is shown, Figure 4 which shows the structure of the lifting mechanism 204, including an upper gear 2041, a lower gear 2041, an upper rotating belt 2042 and a lower rotating belt 2042, the upper gear and the lower gear are engaged with each other, the upper rotating belt is connected with the upper gear and the top heating device 202 respectively, so as to realize the lifting of the top heating device, and the lower rotating belt is connected with the lower gear and the bottom heating device respectively, so as to realize the lifting of the bottom heating device.

[0139] Referring to Figure 5 , a logic block diagram of a control method of a cooking equipment provided by an embodiment of the present application is shown, Figure 5 which shows a logic control of a control method of a cooking equipment, when a user selects a baking mode, the recommended temperature of the cooking food material and the cooking time are selected, it is judged whether the initial cooking time is within a preset time threshold range at the temperature, if less than a first time threshold, the cooking time is increased, if greater than a second time threshold, the cooking time is reduced, so as to determine the target cooking time. After determining the target cooking time, it is determined whether the first heat generated by the heating device radiating to the cooking food material and making the cooking food material reach a mature state and the second heat required to be absorbed by the cooking food material to reach the mature state are matched, if the first heat is greater than the product of the second heat and a correction coefficient, the lifting mechanism is controlled to drive the heating device away from the cooking food material; if the first heat is less than the product of the second heat and the correction coefficient, the lifting mechanism is controlled to drive the heating device to approach the cooking food material. After adjusting the distance between the heating device and the cooking food material, cooking is carried out based on the adjusted distance.

By adjusting the distance between the heating devices and the cooking food according to the first heat generated by the heating devices radiated to the cooking food and making the cooking food reach the mature state and the second heat required to be absorbed by the cooking food to reach the mature state, local overheating or insufficient heating is avoided, and the cooking food is heated more uniformly.
