Description

Technical Field

[0001] This invention relates to the field of intelligent kitchen appliance technology, and in particular to a control method, device and cooking machine for safe ingredient feeding in a cooking machine. Background Technology

[0002] With the continuous improvement of living standards, people are paying more and more attention to healthy and delicious food. As a modern technological product, cooking machines are intelligently cooked by microcomputer control, realizing multiple functions such as automatic stir-frying, braising, and stewing, improving cooking efficiency and saving labor, and enhancing the automation level of kitchen work. Intelligent cooking equipment is gradually becoming popular in thousands of households.

[0003] Currently, most cooking machines offer both fully automatic and semi-automatic functions. Fully automatic cooking involves simultaneously adding seasonings and ingredients to the pot for automatic heating and stirring. While this method may slightly compromise the color, aroma, and flavor of the cooked dishes, it requires less skill from the operator compared to traditional cooking methods that rely heavily on experience and manual labor. Semi-automatic cooking requires adding ingredients and seasonings step-by-step according to a recipe, at appropriate times during the cooking process, resulting in dishes with better taste and color. Currently, the semi-automatic mode of cooking machines follows preset steps and alerts the user when ingredients need to be added. However, during stewing or boiling functions, a large amount of high-temperature steam is generated inside the pot. When the user opens the lid to add ingredients, the accumulated high-temperature steam bursts out from the feeding window, posing a risk of scalding and compromising safety.

[0004] Therefore, there is an urgent need to develop a control method, device, and cooking machine for safe ingredient feeding in cooking machines, which can improve the safety of users feeding ingredients during the cooking process and prevent high-temperature steam from gushing out of the feeding window and scalding users. Summary of the Invention

[0005] This invention provides a control method, device, and cooking machine for safe ingredient feeding in a cooking machine, which at least solves the technical problem that the safety of ingredient feeding by the user cannot be guaranteed during the cooking process, and avoids scalding the user by a large amount of high-temperature steam gushing out from the ingredient feeding window.

[0006] To achieve the above objectives, the present invention provides a control method for safe food feeding in a cooking machine, wherein the cooking machine has a cover assembly, the cover assembly being provided with a food feeding cover, a vent temperature measuring device, and a cover motor for driving the opening and closing of the food feeding cover, the vent temperature measuring device being used to detect the temperature of the vent of the food feeding cover, and the method comprising:

[0007] When a feeding instruction is received, the temperature of the air outlet is detected and determined to be greater than the first preset safety temperature threshold.

[0008] If the temperature at the air outlet is greater than the first preset safe temperature threshold, the heating power of the cooking machine is adjusted until the temperature at the air outlet is less than or equal to the first preset safe temperature threshold.

[0009] If the temperature at the outlet is less than or equal to the first preset safety temperature threshold, the upper cover motor is controlled to drive the feeding cover to open and close to the first preset angle at a first preset speed. This facilitates the slow release of steam from the outlet to achieve the purpose of cooling. This allows control over the amount of steam released, ensuring that the high-temperature steam does not rush out at once and injure the user, thus providing sufficient safety and preparing for further reduction of the outlet temperature.

[0010] Detect and determine whether the temperature at the air outlet is less than a second preset safe temperature threshold, wherein the second preset safe temperature threshold is less than the first preset safe temperature threshold;

[0011] If the temperature at the air outlet is less than the second preset safety temperature threshold, the upper cover motor is controlled to drive the feeding cover to open and close to the maximum opening angle at the second preset speed, and a feeding prompt is issued.

[0012] This invention provides a method for controlling the safe feeding of ingredients in a cooking machine. By setting two different safety temperature thresholds, it effectively prevents users from being scalded by hot steam emanating from the vent, thus improving safety. When the vent temperature exceeds the first preset safety temperature threshold, the heating power of the cooking machine is reduced; when the vent temperature is below the first preset safety temperature threshold, the heating power is not further reduced. This improves safety while also preventing excessive reduction in heating power from affecting heating efficiency.

[0013] In one possible implementation, the control method for safe ingredient dispensing in the cooking machine further includes:

[0014] If the temperature at the air outlet is greater than or equal to the second preset safety temperature threshold, the upper cover motor is controlled to drive the feeding cover to open and close at a first preset speed to a second preset angle and then stop opening. The second preset angle is greater than the first preset angle. As the opening angle gradually increases from the first preset angle to the second preset angle, the steam temperature will continuously decrease, and the high-temperature steam will be gradually released, preventing it from rushing towards the users waiting to feed.

[0015] In one possible implementation, after receiving the feeding instruction and before detecting and determining whether the outlet temperature is greater than the first preset safety temperature threshold, the method further includes:

[0016] The control mechanism drives the upper cover motor to open and close the feeding cover at a third preset speed to a third preset angle, wherein the third preset speed is greater than the first preset speed, and the third preset angle is less than the first preset angle. Opening the feeding cover to the third preset angle facilitates the acquisition and detection of the vent temperature, providing a reliable temperature reading for gradually reducing the heating power. It also helps to promptly acquire the vent temperature just below the first preset safety temperature threshold. Since the feeding cover temporarily stops opening after reaching the third preset angle, and the heating power of the cooking machine is gradually reduced at intervals, the reduction in heating power is stopped when the vent temperature is detected to be just below the first preset safety temperature threshold, thus minimizing the risk of a deterioration in cooking performance due to excessively low heating power.

[0017] In one possible implementation, the method involves detecting and determining whether the outlet temperature is less than the second preset safety temperature threshold. If the outlet temperature is greater than or equal to the second preset safety temperature threshold, the method further includes:

[0018] The system detects and determines whether the feeding cover is open to the second preset angle.

[0019] If the feeding cover opens to the second preset angle, then control the cover motor to drive the feeding cover to open to the maximum opening angle.

[0020] In one possible implementation, after the upper cover motor drives the feeding upper cover to open to the maximum opening angle, the method further includes:

[0021] Determine if the feeding time is greater than the preset feeding time;

[0022] If the feeding time is longer than the preset feeding time, the upper cover motor is controlled to drive the feeding cover to close, and the heating power of the cooking machine is adjusted.

[0023] In one possible implementation, after the cover motor drives the feeding cover to open to the maximum opening angle, the method further includes:

[0024] Detect whether the position of the stirring blade at the lower end of the cover assembly is within a preset angle range;

[0025] If the position of the stirring blade is not within the preset angle range, the angle of the stirring blade is adjusted until the position of the stirring blade is within the preset angle range.

[0026] The present invention also provides a control method for safe food feeding in a cooking machine. The cooking machine has a cover assembly, on which a food feeding cover, a vent temperature measuring device, and a cover motor for driving the opening and closing of the food feeding cover are provided. The vent temperature measuring device is used to detect the temperature of the vent of the food feeding cover. The method includes:

[0027] When a feeding instruction is received, the temperature of the air outlet is detected and determined to be less than the first preset safety temperature threshold.

[0028] If the outlet temperature is less than the first preset safety temperature threshold, detect and determine whether the outlet temperature is less than the second preset safety temperature threshold.

[0029] If the temperature at the air outlet is less than the second preset safety temperature threshold, the upper cover motor is controlled to drive the feeding upper cover to open to the maximum opening angle, and a feeding prompt is issued.

[0030] The present invention also provides a control method for safe feeding of ingredients in a cooking machine. By detecting and determining whether the temperature of the air outlet is less than the first preset safe temperature threshold, and then detecting and determining whether the temperature of the air outlet is less than the second preset safe temperature threshold, the temperature of the air outlet is already within the safe temperature range. The upper cover motor can be directly controlled to drive the feeding cover to open to the maximum opening angle, reminding the user to feed the ingredients, thus eliminating the need to perform other steps.

[0031] The present invention also provides a control device for a cooking machine, the control device comprising:

[0032] The detection module includes a temperature detection module and an angle detection module. The temperature detection module is used to detect whether the temperature of the air outlet of the feeding cover is less than a second preset safety temperature threshold and whether the temperature of the air outlet of the feeding cover is greater than a first preset safety temperature threshold. The angle detection module is used to detect whether the feeding cover is opened or closed to the second preset angle.

[0033] The drive module is used to drive the opening and closing of the feeding cover;

[0034] The power adjustment module is used to control the heating power of the cooking machine. If the temperature at the air outlet is greater than the first preset safety temperature threshold, the power adjustment module adjusts the heating power of the cooking machine. If the drive module drives the feeding cover to close, the power adjustment module adjusts the heating power of the cooking machine.

[0035] The main control module is electrically connected to the detection module, the drive module, and the power adjustment module. If the detection module detects that the temperature of the air outlet of the feeding cover is greater than the first preset safety temperature threshold, the main control module controls the power adjustment module to adjust the heating power of the cooking machine. If the detection module detects that the temperature of the air outlet of the feeding cover is less than or equal to the first preset safety temperature threshold, the main control module controls the drive module to drive the feeding cover to open to a first preset angle. If the detection module detects that the temperature of the air outlet of the feeding cover is less than the second preset safety temperature threshold, and / or the detection module detects that the feeding cover is open to the second preset angle, the main control module controls the drive module to drive the feeding cover to open to the maximum opening angle.

[0036] The present invention also provides a cooking machine, including a memory and a processor, wherein the memory and the processor are connected;

[0037] The memory is used to store computer programs;

[0038] The processor is used to implement the above-described method when the computer program is executed.

[0040] The present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the above-described method.

[0041] The control method, device, and cooking machine for safe food feeding provided by this invention can improve the safety of food feeding in the cooking machine, prevent users from being scalded by high-temperature steam escaping from the vent, ensure that the temperature of the vent drops to a sufficiently safe temperature before issuing a food feeding prompt, and also prevent the heating power of the cooking machine from being reduced too much in order to lower the temperature of the vent, thus affecting the heating efficiency and cooking effect.

[0085] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0086] The safe food feeding control method for a cooking machine provided in this application is based on a cooking machine. The structure of the cooking machine is first illustrated below.

[0087] refer to Figure 1 The diagram shows the structure of a cooking machine, which includes a pot body 100, a body 200, and a lid assembly 300. The lid assembly 300 covers the pot body 100, which can be placed on the body 200. A heating inner liner 110 is provided inside the body 200 for heating the pot body 100 and the food inside. The lid assembly 300 is provided with a feeding cover 310, a vent temperature measuring device 320, and a cover motor 311 for driving the feeding cover 310 to open and close. The vent temperature measuring device 320 is used to detect the temperature of the vent of the feeding cover 310. The vent temperature measuring device 320 is located on the edge of the feeding cover 310. The feeding cover 310 is opened for feeding food. A front baffle 330 is also provided on the edge of the feeding cover 310 to block steam and provide safety protection.

[0088] refer to Figure 1 and Figure 2 As shown, a stirring blade 341 extending into the pot body 100 is rotatably disposed inside the lid assembly 300, and the stirring blade 341 stirs the food put into the pot body 100.

[0089] refer to Figure 3 As shown, the cover motor 311 is connected to the feeding cover 310 via a transmission device 312, which can be a pair of meshing gears. One gear is connected to the output end of the cover motor 311, and the rear end of the feeding cover 310 is fixedly connected to the central shaft of the other gear, thereby enabling the cover motor 311 to drive a pair of meshing gears to drive the feeding cover 310 to open and close.

[0090] refer to Figure 1 and Figure 2 As shown, three body temperature sensors 230 are installed on the top of the body 200. The three body temperature sensors 230 are the first temperature sensor 231, the second temperature sensor 232, and the third temperature sensor 233. The first temperature sensor 231, the second temperature sensor 232, and the third temperature sensor 233 are equidistant from the central axis of the pot body 100, which facilitates the detection of the temperature at different positions of the heating inner pot 110. A heating coil 210 is provided on the inner side of the top of the body 200. The heating coil 210 generates a magnetic field to heat the heating inner pot 110. A control circuit board 220 is installed inside the body 200. The control circuit board 220 has a control circuit. A connector 240 is provided on the side of the body 200. The control circuit is connected to the stirring motor 340 and the top cover motor 311 through the connector 240. The stirring motor 340 is used to drive the stirring blade 341 to rotate for stirring.

[0091] During the cooking process of a semi-automatic cooking machine, ingredients need to be added step by step according to the recipe. For example, seasonings and side dishes are added step by step according to the recipe. The cooking process generates a large amount of high-temperature steam. When the feeding cover 310 is opened directly to add ingredients, the high-temperature steam will inevitably escape quickly and burn the user, which is not safe to use. In addition, in order to ensure the taste of the food or dishes cooked by the cooking machine, the time reserved for adding ingredients during the entire cooking process is very limited. Therefore, when it is necessary to open the feeding cover 310 to add ingredients, the temperature of the vent of the feeding cover 310 needs to be reduced quickly before adding ingredients. The optimal time for adding ingredients should not be missed because the temperature of the vent of the feeding cover 310 does not drop for a long time. One way to quickly reduce the temperature of the vent of the feeding cover 310 is to reduce the heating power. However, reducing the heating power too much will affect the continued cooking after the ingredients are added, affecting the heating efficiency, which will affect the taste of the cooked dishes and also waste energy.

[0092] In light of the above background, the safe food feeding control method for a cooking machine provided in this application, by setting two different safe temperature thresholds, reduces the temperature of the steam outlet to a suitable level, effectively preventing users from being scalded by hot steam and improving safety. When the steam outlet temperature exceeds the first preset safe temperature threshold, the heating power of the cooking machine is reduced; when the steam outlet temperature is below the first preset safe temperature threshold, the heating power of the cooking machine will not be reduced further. This improves safety while also preventing excessive reduction in heating power from affecting heating efficiency and resulting in poor cooking performance.

[0093] The following will describe in detail the safe food feeding control method for the cooking machine provided in this application through specific embodiments. It is understood that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0094] Figure 7 This is a flowchart illustrating a control method for safely dispensing ingredients into a cooking machine, provided as an embodiment of this application. The controller of the cooking machine is the executing entity of this method.

[0095] This application provides a method for controlling the safe feeding of ingredients in a cooking machine. The cooking machine includes a cover assembly 300, on which a feeding cover 310, a vent temperature measuring device 320, and a cover motor 311 for driving the opening and closing of the feeding cover 310 are mounted. The vent temperature measuring device 320 detects the temperature of the vent of the feeding cover 310. Figure 7 As shown, the safe food feeding control method of this cooking machine includes:

[0096] S00. When a feeding instruction is received, S10. Detect and determine whether the temperature of the air outlet is greater than the first preset safety temperature threshold.

[0097] S20. If the temperature at the outlet is greater than the first preset safe temperature threshold, adjust the heating power of the cooking machine until the temperature at the outlet is less than or equal to the first preset safe temperature threshold.

[0098] S30. If the temperature at the air outlet is less than or equal to the first preset safe temperature threshold, control the upper cover motor 311 to drive the feeding upper cover 310 to open and close to the first preset angle at the first preset speed.

[0099] S40. Detect and determine whether the outlet temperature is less than the second preset safety temperature threshold, where the second preset safety temperature threshold is less than the first preset safety temperature threshold.

[0100] S50. If the outlet temperature is lower than the second preset safety temperature threshold, the upper cover motor 311 is controlled to drive the feeding upper cover 310 to open and close to the maximum opening angle at the second preset speed, and a feeding prompt is issued. (Reference) Figure 6 The image shows the feeding cover 310 open to its maximum opening angle β, at which point feeding can begin.

[0101] This embodiment provides a safe food feeding control method for a cooking machine. When food needs to be fed, the temperature of the air outlet is detected. When the air outlet temperature drops below a first preset safety temperature threshold, the upper cover motor 311 drives the food feeding cover to open to a first preset angle. When the air outlet temperature drops below a second preset safety temperature threshold, the cover is opened to the maximum opening angle at a second preset speed. At this time, the food feeding operation is performed into the cooking machine. This ensures that the temperature of the air outlet has dropped to a safe range and will not burn the user when feeding, thus ensuring safe food feeding.

[0102] Furthermore, in the control method for safe feeding of a cooking machine provided in this embodiment, if the temperature at the gas outlet is greater than the first preset safe temperature threshold, the heating power of the cooking machine is reduced until the temperature at the gas outlet is less than or equal to the first preset safe temperature threshold, and the heating power of the cooking machine will not be reduced further, thereby avoiding excessive reduction of the heating power of the cooking machine from affecting the heating efficiency.

[0103] In step S20, if the outlet temperature exceeds the first preset safe temperature threshold, the heating power of the cooking machine is adjusted, specifically by reducing the heating power to lower the outlet temperature. This can be achieved by gradually reducing the heating power at intervals based on the cooking recipe's operating parameters.

[0104] In one possible implementation, the heating power can be gradually reduced according to the cooking recipe's operating parameters at intervals. Once the temperature at the steam outlet is detected to be less than or equal to a preset first safe temperature threshold, the adjustment of the cooking machine's heating power can be stopped, and step S30 can be executed.

[0105] The cooking recipe parameters can be the time corresponding to different recipes, or the temperature of the bottom of the pot (100°C).

[0106] In step S30, if the temperature at the outlet is less than or equal to the first preset safety temperature threshold, the upper cover motor 311 is controlled to drive the feeding cover 310 to open and close to the first preset angle at the first preset speed. Driving the feeding cover 310 to open to the first preset angle at the first preset speed facilitates the slow release of steam from the outlet to achieve the purpose of cooling. This controls the amount of steam released, ensuring that if there is still high-temperature steam in the pot 100, it will not rush out and injure the user at once, thus providing sufficient safety and preparing for further reduction of the outlet temperature.

[0107] In one possible implementation, the first preset angle can be set at 15°, and this first preset angle can be estimated by the speed and running time of the top cover motor 311.

[0108] In step S40, it is detected and determined whether the temperature at the air outlet is lower than the second preset safety temperature threshold, which is lower than the first preset safety temperature threshold. In step S50, if the temperature at the air outlet is lower than the second preset safety temperature threshold, the cover motor 311 is controlled to drive the feeding cover 310 to open and close to the maximum opening angle at a second preset speed, and a feeding prompt is issued. The fact that the air outlet temperature is detected to be lower than the second preset safety temperature threshold indicates that the amount of air generated inside the pot 100 is already small and the air temperature is relatively low, preventing a sudden surge towards the user waiting to feed.

[0109] In one possible implementation method, refer to Figure 9 As shown, the control method for safe ingredient feeding in a cooking machine also includes:

[0110] S61. If the outlet temperature is greater than or equal to the second preset safety temperature threshold, the upper cover motor 311 is controlled to drive the feeding upper cover 310 to open and close at a first preset speed to a second preset angle and then stop opening the cover. The second preset angle is greater than the first preset angle. The purpose is to further open the feeding upper cover 310 to facilitate the escape of more steam, thereby rapidly reducing the outlet temperature.

[0111] refer to Figure 5 The diagram shows the state of the feeding cover 310 when it is opened to the second preset angle α.

[0112] It is easy to understand that if the outlet temperature is less than or equal to the first preset safety temperature threshold and greater than or equal to the second preset safety temperature threshold, the way to reduce the outlet temperature is to control the upper cover motor 311 to drive the feeding upper cover 310 to open to the second preset angle at the first preset speed and then stop opening the cover, instead of adjusting the heating power of the cooking machine to reduce the outlet temperature. This can avoid the heating power of the cooking machine being reduced too much and affecting the heating efficiency.

[0113] In one possible implementation method, refer to Figure 8 As shown, after receiving the feeding instruction and before detecting and determining whether the outlet temperature is greater than the first preset safety temperature threshold, the process also includes:

[0114] S01. Control the upper cover motor 311 to drive the feeding upper cover 310 to open and close to a third preset angle at a third preset speed, wherein the third preset speed is greater than the first preset speed, and the third preset angle is less than the first preset angle. The determination of this third preset angle is estimated by the speed and running time of the upper cover motor 311.

[0115] Among them, the upper cover motor 311 drives the feeding upper cover 310 to open and close to the third preset angle at the third preset speed. When the feeding upper cover 310 is opened to the third preset angle, the direction of the high temperature steam can be controlled to discharge the accumulated high temperature steam in advance.

[0116] The direction of the high-temperature steam outlet can be controlled through the structure of the feeding cover 310, as shown in the reference. Figure 4 As shown, when the feeding cover 310 is opened to the third preset angle range, the front baffle 330 of the feeding cover 310 can block the steam outlet in front, so that the high temperature steam can only flow out from both sides of the feeding cover 310 opening direction, minimizing the risk of the high temperature steam surging out when the feeding cover 310 is opened and scalding the user.

[0117] The feeding cover 310 is opened to the third preset angle. On the one hand, this facilitates the collection and detection of the vent temperature. At this angle, the high-temperature steam will pass through the vent temperature measuring device 320, providing a reliable temperature for gradually reducing the heating power. On the other hand, it helps to collect the vent temperature in a timely manner when it is just below the first preset safe temperature threshold. Since the feeding cover 310 stops opening after opening to the third preset angle, the heating power of the cooking machine is gradually reduced at intervals. When the vent temperature is detected to be just below the first preset safe temperature threshold, the heating power of the cooking machine is stopped from being reduced further, so as to avoid reducing the heating power too low and causing a deterioration in the cooking effect.

[0118] In one possible implementation method, refer to Figure 9 As shown, the system detects and determines whether the outlet temperature is lower than the second preset safety temperature threshold. If the outlet temperature is greater than or equal to the second preset safety temperature threshold, the system further includes:

[0119] S60. Detect and determine whether the feeding cover 310 is opened to the second preset angle;

[0120] S50. If the feeding cover 310 opens to the second preset angle, control the cover motor 311 to drive the feeding cover 310 to open to the maximum opening angle and issue a feeding prompt.

[0121] Considering that seasonings or side dishes need to be added before the food is fully cooked during the cooking process, the entire safe food dispensing control method of the cooking machine operates within a very short time, requiring the outlet temperature to be reduced to a suitable range before opening the lid for food dispensing. Therefore, if the outlet temperature is detected to be below the second preset safe temperature threshold for an extended period, the system checks and determines whether the dispensing cover 310 is open to the second preset angle. If at least one of the following conditions is met—the outlet temperature being below the second preset safe temperature threshold and / or the dispensing cover 310 being open to the second preset angle—the cover motor 311 is controlled to drive the dispensing cover 310 to its maximum opening angle, at which point a food dispensing prompt is issued, reminding the user to add food.

[0122] In one possible implementation, the method involves detecting and determining whether the outlet temperature is less than a second preset safety temperature threshold. If the outlet temperature is greater than or equal to the second preset safety temperature threshold, the method further includes:

[0123] S61. If the outlet temperature is greater than or equal to the second preset safety temperature threshold, the upper cover motor 311 is controlled to drive the feeding upper cover 310 to open and close at a first preset speed to a second preset angle and then stop opening the cover. The second preset angle is greater than the first preset angle. The purpose is to further open the feeding upper cover 310 to facilitate the escape of more steam, thereby rapidly reducing the outlet temperature.

[0124] S60. Detect and determine whether the feeding cover 310 is opened to the second preset angle.

[0125] In one possible implementation method, refer to Figure 11 As shown, step S50 can be performed in two steps:

[0126] S51, Control the upper cover motor 311 to drive the feeding upper cover 310 to open and close to the maximum opening angle at the second preset speed;

[0127] S52, Issue a feeding prompt.

[0128] It's easy to understand that waiting for the steam outlet temperature to be lower than the second preset safety temperature threshold indicates that the steam output from the pot 100 is already low and the steam temperature is also low. Alternatively, it can be detected and determined that the feeding lid 310 has been opened to the second preset angle. As the opening angle gradually increases from the first preset angle to the second preset angle, the steam temperature will continue to decrease, and the high-temperature steam stored in the pot 100 will be gradually released, preventing it from rushing towards the user waiting to add ingredients. When the feeding lid 310 has been opened to the second preset angle, the lid motor 311 is controlled to drive the feeding lid 310 to open to the maximum opening angle position at the second preset speed. The lid motor 311 is then stopped, and a feeding prompt is issued to remind the user to add ingredients safely. After the user has finished adding ingredients, the lid motor 311 is controlled to close the lid in the closing direction, and the heating power is adjusted according to the cooking steps to continue working.

[0129] Feeding prompts can be indicated by flashing lights, voice prompts such as "Please feed materials", or a buzzer sound.

[0130] In one possible implementation method, refer to Figure 10 As shown, after the upper cover motor 311 drives the feeding upper cover 310 to open to the maximum opening angle, it also includes: S80, judging whether the feeding time is greater than the preset feeding time;

[0131] S70. If the feeding time exceeds the preset feeding time, the upper cover motor 311 is controlled to drive the feeding cover 310 to close, and the heating power of the cooking machine is adjusted. This can be done by gradually increasing the heating power of the cooking machine. The user completes feeding within the preset feeding time; if the feeding time exceeds the preset feeding time, it is assumed that the user has completed feeding. After completing one safe feeding step, proceed to step S00.

[0132] If the feeding time is less than or equal to the preset feeding time, continue to wait until the feeding time is greater than the preset feeding time, then start to execute step S70, control the upper cover motor 311 to drive the feeding upper cover 310 to close, and adjust the heating power of the cooking machine.

[0133] It's easy to understand that the preset feeding time is a time interval, such as 1 minute, 2 minutes, etc.; the feeding time can be calculated from the moment the feeding cover 310 is opened to its maximum opening angle, until the preset feeding time has elapsed, at which point step S80 is executed. Of course, if the time elapsed from the starting point of the timing has not reached the preset feeding time, it is considered that the feeding time has not exceeded the preset feeding time, thus determining whether the feeding time exceeds the preset feeding time.

[0134] In one possible implementation, the user can press a button or touch screen after feeding the ingredients. Upon receiving the user's button or touch screen operation, the cooking machine controls the cover motor 311 to drive the feeding cover 310 to close in the closing direction. Once the cover is closed, the feeding cover 310 is closed, and the heating power of the cooking machine is adjusted, which can be done by gradually increasing the heating power of the cooking machine.

[0135] In one possible implementation method, refer to Figure 11 As shown, after the upper cover motor 311 drives the feeding upper cover 310 to open to the maximum opening angle, it also includes:

[0136] S90. Check whether the position of the stirring blade 341 at the lower end of the cover assembly 300 is within the preset angle range;

[0137] S91. If the position of the stirring blade 341 is not within the preset angle range, adjust the angle of the stirring blade 341 until the position of the stirring blade 341 is within the preset angle range.

[0138] The purpose of performing steps S90 and S91 is to prevent the stirring blade 341 from being located directly below the opening of the feeding cover 310, thus blocking the feeding path and affecting the feeding process. The angle of the stirring blade 341 can be adjusted by controlling the stirring motor 340 to drive the stirring blade 341 to rotate.

[0139] This embodiment provides a safe food feeding control method for a cooking machine. It utilizes the method of first controlling the direction of high-temperature steam output and reducing the temperature of the steam, then slowly opening the top cover to control the amount of steam output, and waiting for the steam temperature to reach the second preset safe temperature threshold before quickly and completely opening the top cover. This method facilitates safe food feeding by the user, not only avoiding the reduction of heating power due to excessively low temperatures, which would lead to poor cooking results, but also effectively improving the safety of food feeding operations in the cooking machine.

[0140] In one possible implementation, the control method for safe food feeding in a cooking machine provided in this embodiment, when a food feeding command is received, the upper cover motor 311 is activated to open the food feeding cover 310 to a third preset angle at a third preset speed. When the food feeding cover 310 is opened to the third preset angle, the direction of the high-temperature steam outlet can be controlled to pre-discharge the accumulated high-temperature steam and heat. Then, at intervals, the heating power is gradually reduced according to the operating parameters of the cooking recipe. When the temperature at the outlet is detected to be less than or equal to a preset first preset safe temperature threshold, the adjustment of the heating power of the cooking machine is stopped. Restart the cover motor 311 to open the feeding cover 310 to the first preset angle at the first preset speed. Wait until the temperature at the air outlet is detected to be lower than the second preset safety temperature threshold, or until the feeding cover 310 is opened to the second preset angle. Then, control the cover motor 311 to drive the feeding cover 310 to open to the maximum opening angle at the second preset speed and stop opening the cover. Issue a feeding prompt to remind the user to feed the material. After the user finishes feeding the material, control the cover motor 311 to drive the feeding cover 310 to close the cover. After the cover is closed, adjust the heating power to complete a safe feeding operation.

[0141] This invention also provides another method for controlling the safe feeding of ingredients in a cooking machine. The cooking machine has a cover assembly 300, on which a feeding cover 310, a vent temperature measuring device 320, and a cover motor 311 for driving the opening and closing of the feeding cover 310 are provided. The vent temperature measuring device 320 is used to detect the temperature of the vent of the feeding cover 310, with reference to... Figure 12 As shown, the safe food feeding control method of this cooking machine includes:

[0142] S00. When a feeding instruction is received, S10. Detect and determine whether the temperature of the air outlet is less than the first preset safety temperature threshold.

[0143] S40. If the outlet temperature is less than or equal to the first preset safety temperature threshold, detect and determine whether the outlet temperature is less than the second preset safety temperature threshold.

[0144] S50. If the outlet temperature is lower than the second preset safety temperature threshold, control the top cover motor 311 to open the cover to the maximum opening angle and issue a feeding prompt. Alternatively, control the top cover motor 311 to open the cover to the maximum opening angle at the second preset speed and issue a feeding prompt.

[0145] The purpose of this safe ingredient feeding control method in the cooking machine is to ensure that when an ingredient feeding command is received, the condition that the outlet temperature is below the second preset safety temperature threshold has already been met, at which point ingredient feeding can proceed directly. This facilitates safe ingredient feeding for users, eliminates the need for additional steps, and effectively improves the safety of the cooking machine's ingredient feeding operation.

[0146] If the temperature at the vent is consistently lower than the second preset safety temperature threshold, it indicates that no high-temperature steam is generated or remains inside the pot 100. The cover motor 311 drives the feeding cover 310 to open to the maximum opening angle at the second preset speed and issues a feeding prompt.

[0147] In one possible implementation, step S10 involves detecting and determining whether the outlet temperature is less than a first preset safe temperature threshold. If the outlet temperature is greater than the first preset safe temperature threshold, then step S20 involves adjusting the heating power of the cooking machine until the outlet temperature is less than or equal to the first preset safe temperature threshold.

[0148] In one possible implementation, in step S40, if the outlet temperature is less than or equal to the first preset safety temperature threshold, the outlet temperature is detected and determined to be less than the second preset safety temperature threshold. If the outlet temperature is detected and determined to be greater than or equal to the second preset safety temperature threshold, then step S61 is executed, controlling the upper cover motor 311 to drive the feeding upper cover 310 to open and close at a first preset speed to a second preset angle and then stopping the opening. The purpose of executing step S61 is to facilitate the escape of more steam, thereby rapidly reducing the outlet temperature. After step S61, controlling the cover motor 311 to drive the feeding cover 310 to open and close to the second preset angle at the first preset speed and then stopping the opening, step S60 is executed to detect and determine whether the feeding cover 310 has opened to the second preset angle. If the feeding cover 310 is detected to have opened to the second preset angle, the cover motor 311 is controlled to drive the feeding cover 310 to open and close to the maximum opening angle at the second preset speed, and a feeding prompt is issued. It is easy to understand that if step S60 is executed to detect and determine whether the feeding cover 310 has opened to the second preset angle, and it is detected that the feeding cover 310 has not opened to the second preset angle, then step S61 is returned to be executed, controlling the cover motor 311 to drive the feeding cover 310 to open and close to the second preset angle at the first preset speed and then stopping the opening, until the feeding cover 310 is opened to the second preset angle.

[0151] The drive module 420 is used to drive the opening and closing of the feeding cover 310; the drive module 420 can also drive the stirring blade 341 to rotate.

[0152] The power adjustment module 430 is used to control the heating power of the cooking machine.
