[0028] The dynamic pot involved in this application is used for automatically cooking food, and is called a cooking robot, an automatic cooking machine, an automatic cooking machine, etc. It includes a control circuit, a heating system, a stirring system, an air blowing system, a display board, a shell and a sensor. Among them, the control circuit is the core component of the dynamic pot, which is equipped with an integrated circuit chip, which is used to set the working time and temperature according to different foods and cooking methods, control the work of each actuator, and realize the standardization, programming and automation of food cooking.

The software of dynamic cookers includes artificial intelligence algorithms, which can be adjusted intelligently according to different ingredients and dishes. The electronic control system of dynamic cookers is used to execute the instructions of intelligent algorithms and control components such as robotic arms to complete cooking tasks. These structures together ensure that dynamic cookers can complete cooking tasks automatically and accurately.

[0029] like Figure 1 As shown, the temperature control method of the dynamic cooker involved in the present application, in one embodiment, may include the following steps:

[0030] Step 101: Obtain a change relationship between the temperature acceleration of a temperature measuring point of a dynamic cookware and the heating power of a heating plate, wherein the change relationship includes a temperature trend.

[0031] In some examples, the temperature control method involved in the present application may include step 101, namely obtaining the change relationship between the temperature acceleration of the temperature measuring point of the dynamic cookware and the heating power of the heating plate, and the change relationship includes the temperature trend.

[0032] In some examples, the dynamic cookware may include multiple temperature measuring points, at which temperature sensors are provided to sense the temperature. In some examples, the temperature measuring points may be evenly arranged on the heated surface of the cookware. In other examples, the temperature measuring points are arranged unevenly, with a dense arrangement on the heated surface and a sparse arrangement on the non-heated surface. In this case, the temperature can be sensed more accurately and comprehensively.

[0033] In some examples, there may be 2, 3, 4, 5, 6, 7, 8, 9, or 10 temperature measurement points.

[0034] In some examples, the dynamic cooker may be provided with a heating plate on the heating surface, and the heating plate may be disc-shaped to uniformly heat the heating surface. The heating plate has a heating wire in it. The heating wire in the heating plate is controlled by a control circuit to control the heating power.

[0035] In some examples, the dynamic cooker may have a tilt control unit for controlling the tilt of the dynamic cooker relative to the vertical direction. The dynamic cooker having a certain tilt relative to the vertical direction can facilitate the operator to observe the cooking of the dish. The tilt control unit can control the dynamic cooker to have a tilt of 10-90 degrees.

[0036] In some examples, the dynamic cooker may also have a rotation control unit for controlling the rotation of the cooker relative to its axis so that the food therein is heated evenly. In some examples, the rotation control unit may control the cooker to rotate at a certain rotation speed, such as 10 rpm.

[0037] In some examples, the dynamic cooker may also have an ambient thermometer for sensing the ambient temperature.

[0038] In some examples, the dynamic cookware may include a calibration process. During the calibration process, the relationship between the temperature acceleration of multiple temperature measurement points and the heating power of the heating plate may be obtained. The so-called temperature acceleration may be the rate of change of temperature relative to time, that is, the greater the rate of change, the greater the acceleration, and vice versa.

[0039] In some examples, the changing relationship is a series of relationship curves.

[0040] In some examples, the calibration process may also include the changing relationship between the temperature acceleration of the temperature measuring point and the heating power of the heating plate at multiple pot inclination angles, that is, measuring the relationship curves at multiple pot inclination angles. In this case, incorporating the changing relationship under various different inclination conditions can more accurately control the temperature of the frying process at different inclination angles.

[0041] In some examples, the calibration process may also include the changing relationship between the temperature acceleration of the temperature measuring point and the heating power of the heating plate under multiple pan rotation speed conditions, that is, measuring the relationship curves under different pan rotation speeds. In this case, taking into account the changing relationship under various pan rotation speed conditions, the temperature of the frying process at different rotation speeds can be more accurately controlled.

[0042] In some examples, the calibration process may also include the changing relationship between the temperature acceleration of the temperature measuring point and the heating power of the heating plate under multiple real-time ambient temperature conditions, that is, measuring the relationship curves under different environmental stability conditions. In this case, taking into account the changing relationship under various real-time ambient temperature conditions, the temperature of the frying process at different room temperatures can be more accurately controlled.

[0043] In the above series of relationship curves, the trend of temperature change can be included. In this case, the temperature can be quickly stabilized by adjusting the parameters.

[0044] Step 102: Select a corresponding heating scheme according to the temperature trend, where the heating scheme includes a specified temperature.

[0045] In some examples, the corresponding heating scheme is selected according to the temperature trend, and the heating scheme includes a specified temperature. In some examples, the temperature trend obtained during the calibration process can be displayed on a display screen for the user to select a heating scheme. The heating scheme can also be selected by the system's artificial intelligence algorithm after the user selects the frying time. The heating scheme may include at least one of quick frying, slow frying, and stewing. The heating scheme may include a specified temperature, such as a first specified temperature for quick frying, a second specified temperature for slow frying, and a third specified temperature for stewing.

[0046] Step 103: Execute the heating plan. When the temperature at the temperature measuring point is on an upward trend and reaches a specified temperature, reduce the heating power. When the temperature at the temperature measuring point is on a downward trend and reaches a specified temperature, increase the heating power.

[0047] In some examples, the temperature control method involved in the present application may include step 103, that is, executing a heating scheme, reducing the heating power when the temperature at the measuring point is on an upward trend and reaches a specified temperature, and increasing the heating power when the temperature at the measuring point is on a downward trend and reaches a specified temperature.

[0048] In some examples, the heating scheme is selected as quick stir-fry, and the control circuit heats the heated surface with a larger heating power and controls the rotation speed to be fast. In some examples, the temperature sensor value of the temperature measuring point can be read. When the temperature is on an upward trend, when the read value just reaches the specified temperature, the heating power of the heating plate is reduced. At this time, due to the reduction in heating power, the temperature rise slows down and the temperature begins to drop. When it drops to the specified temperature, the heating power is increased. In this case, the temperature can be controlled more evenly and accurately by dynamically adjusting the heating power.

[0049] like Figure 2 As shown, another implementation of the temperature control method of the dynamic cooker involved in the present application may also include the following steps:

[0050] Step 104: Adjust the parameters of the heating scheme so that the temperature of the dynamic cooker is stabilized at a specified temperature.

[0051] In some examples, the parameters of the heating scheme may include parameters such as heating power, rotation speed, inclination angle, etc. Adjusting these parameters, such as adjusting the rotation speed, can quickly stabilize the temperature of the pot at a specified temperature.

[0052] like Figure 3 As shown, a temperature control device for a dynamic cooker provided in an embodiment of the present application, in one implementation manner, includes an acquisition module 310 , a selection module 320 and an execution module 330 .

[0053] The acquisition module 310 is used to acquire the change relationship between the temperature acceleration of the temperature measuring point of the dynamic cookware and the heating power of the heating plate, and the change relationship includes the temperature trend.

[0054] In some examples, the dynamic cookware may include multiple temperature measuring points, at which temperature sensors are provided to sense the temperature. In some examples, the temperature measuring points may be evenly arranged on the heated surface of the cookware. In other examples, the temperature measuring points are arranged unevenly, with a dense arrangement on the heated surface and a sparse arrangement on the non-heated surface. In this case, the temperature can be sensed more accurately and comprehensively.

[0055] In some examples, there may be 2, 3, 4, 5, 6, 7, 8, 9, or 10 temperature measurement points.

[0056] In some examples, the dynamic cooker may be provided with a heating plate on the heating surface, and the heating plate may be disc-shaped to uniformly heat the heating surface. The heating plate has a heating wire in it. The heating wire in the heating plate is controlled by a control circuit to control the heating power.

[0057] In some examples, the dynamic cookware may have an inclination control unit for controlling the inclination of the dynamic cookware with respect to the vertical direction. The dynamic cookware has a certain inclination with respect to the vertical direction, which makes it easier for the operator to observe the cooking of the dish. The inclination control unit can control the dynamic cookware to have an inclination of 10-90 degrees. Incorporating the changing relationship under various inclination conditions can more accurately control the temperature of the cooking process at different inclinations.

[0058] In some examples, the dynamic cookware may also have a rotation control unit for controlling the rotation of the cooker relative to its axis so that the food is heated evenly. In some examples, the rotation control unit may control the cooker to rotate at a certain speed, such as 10 rpm. Taking into account the changing relationship under various cooker speed conditions, the temperature of the frying process at different speeds can be more accurately controlled.

[0059] In some examples, the dynamic cooker may also have an ambient thermometer for sensing the ambient temperature, taking into account the changing relationship under various real-time ambient temperature conditions, and more accurately controlling the temperature of the frying process at different room temperatures.

[0060] In some examples, the dynamic cookware may include a calibration process. During the calibration process, the relationship between the temperature acceleration of multiple temperature measurement points and the heating power of the heating plate may be obtained. The so-called temperature acceleration may be the rate of change of temperature relative to time, that is, the greater the rate of change, the greater the acceleration, and vice versa.

[0061] In some examples, the changing relationship is a series of relationship curves.

[0062] In some examples, the calibration process may further include measuring the changing relationship between the temperature acceleration of the temperature measuring point and the heating power of the heating plate at multiple cookware inclination angles, that is, measuring the relationship curves at multiple cookware inclination angles respectively.

[0063] In some examples, the calibration process may further include measuring the changing relationship between the temperature acceleration of the temperature measuring point and the heating power of the heating plate under multiple pot rotation speed conditions, that is, measuring the relationship curves respectively at different pot rotation speeds.

[0064] In some examples, the calibration process may further include a changing relationship between the temperature acceleration of the temperature measuring point and the heating power of the heating disk under multiple real-time ambient temperature conditions, that is, measuring the relationship curves respectively under different environmental stability conditions.

[0065] In the above series of relationship curves, the trend of temperature change can be included.

[0066] The selection module 320 is used to select a corresponding heating scheme according to the temperature trend, and the heating scheme includes a specified temperature.

[0067] In some examples, the corresponding heating scheme is selected according to the temperature trend, and the heating scheme includes a specified temperature. In some examples, the temperature trend obtained during the calibration process can be displayed on a display screen for the user to select a heating scheme. The heating scheme can also be selected by the system's artificial intelligence algorithm after the user selects the frying time. The heating scheme may include at least one of quick frying, slow frying, and stewing. The heating scheme may include a specified temperature, such as a first specified temperature for quick frying, a second specified temperature for slow frying, and a third specified temperature for stewing.

[0068] The execution module 330 is used to execute the heating scheme. When the temperature at the temperature measuring point is on an upward trend and reaches a specified temperature, the heating power is reduced. When the temperature at the temperature measuring point is on a downward trend and reaches a specified temperature, the heating power is increased.

[0069] In some examples, the heating scheme is selected as quick stir-fry, and the control circuit heats the heated surface with a larger heating power and controls the rotation speed to be fast. In some examples, the temperature sensor value of the temperature measuring point can be read. When the temperature is on an upward trend, when the read value just reaches the specified temperature, the heating power of the heating plate is reduced. At this time, due to the reduction in heating power, the temperature rise slows down and the temperature begins to drop. When it drops to the specified temperature, the heating power is increased. In this case, the temperature can be controlled more evenly and accurately by dynamically adjusting the heating power.

[0070] like Figure 4 As shown, another implementation manner of the dynamic cooker temperature control device provided in the embodiment of the present application may include an acquisition module 410, a selection module 420, an execution module 430 and an adjustment module 440.

[0071] The acquisition module 410 is used to obtain the change relationship between the temperature acceleration of the temperature measuring point of the dynamic cookware and the heating power of the heating plate, and the change relationship includes the temperature trend.

[0072] The selection module 420 is used to select a corresponding heating scheme according to the temperature trend, and the heating scheme includes a specified temperature.

[0073] The execution module 430 is used to execute the heating scheme. When the temperature at the temperature measuring point is on an upward trend and reaches a specified temperature, the heating power is reduced. When the temperature at the temperature measuring point is on a downward trend and reaches a specified temperature, the heating power is increased.

[0074] The adjustment module 440 is used to adjust the parameters of the heating scheme so that the temperature of the dynamic cookware is stabilized at a specified temperature.

[0075] In some examples, the parameters of the heating scheme may include parameters such as heating power, rotation speed, inclination angle, etc. Adjusting these parameters, such as adjusting the rotation speed, can quickly stabilize the temperature of the pot at a specified temperature.

[0076] The above contents are further detailed descriptions of the present application in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application.
