[0001] The present invention relates to the technical field of hot air heating, and in particular to a hot air heating device and a control method, a device and a readable storage medium thereof. Background Art

[0002] In the related art, hot air heating products mostly control the start and stop of the heating tube through a fixed frequency to maintain the heating temperature. However, the temperature fluctuation caused by the heating tube started and stopped at a fixed frequency is large, and the actual heating effect is poor.

[0003] Therefore, how to overcome the above-mentioned technical defects has become a technical problem that needs to be solved urgently. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of the present invention provides a control method for a hot air heating device.

[0006] A second aspect of the present invention provides a control device for hot air heating equipment.

[0007] A third aspect of the present invention provides a control device for hot air heating equipment.

[0008] A fourth aspect of the present invention provides a readable storage medium.

[0009] A fifth aspect of the present invention provides a hot air heating device.

[0010] In view of this, a first aspect of the present invention provides a control method for a hot air heating device, the hot air heating device comprising a cavity, a temperature sensor, an electromagnetic coil and a magnetic conductive part, the temperature sensor is used to detect the current temperature value of the cavity, the electromagnetic coil is used to generate an electromagnetic field for heating the magnetic conductive part, and the control method of the hot air heating device comprises: obtaining a first target temperature value; controlling the electromagnetic coil to operate at a first power to make the magnetic conductive part heat up; adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value.

[0011] The present application defines a control method for a hot air heating device, which includes a cavity, a temperature sensor, an electromagnetic coil and a magnetic conductive member.

[0012] Specifically, the cavity is used to contain materials, and the materials are heated by high-temperature airflow in the cavity. When the hot air heating device is a cooking device such as an air fryer or an oven, the materials are food, and the food in the cavity is cooked into a finished product under the action of the high-temperature airflow. When the hot air heating device is a cleaning device such as a dishwasher or a disinfection cabinet, the materials are tableware, and the tableware in the cavity is dried and sterilized by the high-temperature airflow.

[0013] The electromagnetic coil and the magnetic conductive part are used together. The electromagnetic coil can generate an electromagnetic field. The magnetic conductive part heats up in the electromagnetic field. The high-temperature magnetic conductive part blows out a high-temperature airflow through rotation, and the high-temperature airflow acts on the cavity. The temperature sensor is set corresponding to the cavity, and the temperature sensor can detect the current temperature value of the cooking cavity.

[0014] On this basis, in the process of controlling the operation of the hot air heating device, the first target temperature value is first obtained. The target temperature value corresponds to the temperature value that the cooking cavity needs to reach. The specific value of the first target temperature value is related to the type of material to be heated and the function to be achieved. After obtaining the first target temperature value, the electromagnetic coil is controlled to operate at the first power, and the magnetic conductive part is controlled to rotate at the same time. The first power corresponds to the high power gear of the electromagnetic coil, and the highest gear can be selected specifically. Under the action of the electromagnetic coil operating at the first power, the magnetic conductive part heats up rapidly, and the first target temperature value in the corresponding cavity rises rapidly. In this process, the temperature sensor monitors the current temperature value of the cavity in real time, and adjusts the power of the electromagnetic coil according to the first target temperature value and the current temperature value to maintain the current temperature value of the cavity near the first target temperature value.

[0015] Compared with the related technology of controlling the start and stop of the heating tube by a fixed start and stop frequency, the method of adjusting the power of the electromagnetic coil by coordinating the current temperature value of the cavity and the first target temperature value is more flexible and reliable, which is conducive to reducing the temperature difference between the current temperature value and the first target temperature value, thereby solving the technical problem of large fluctuations in cavity temperature. At the same time, the control method defined in the present application can timely reduce the power of the electromagnetic coil when the current temperature value is greater than the first target temperature value, so as to reduce energy consumption on the basis of meeting the heating demand. Thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment.

[0016] In addition, the control method of the hot air heating device provided by the present invention may also have the following additional technical features:

[0017] In some technical solutions, optionally, the power of the electromagnetic coil is adjusted according to the first target temperature value and the current temperature value, including: in response to the current temperature value being greater than or equal to the first target temperature value, controlling the electromagnetic coil to operate at a second power.

[0018] In this technical solution, in the process of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value, the magnetic conductive part heats up rapidly, and the first target temperature value in the corresponding cavity rises rapidly. In this process, the temperature sensor monitors the current temperature value of the cavity in real time, and when the current temperature value rises to the first target temperature value, the power of the electromagnetic coil is adjusted according to the first target temperature value and the current temperature value to maintain the current temperature value of the cavity near the first target temperature value.

[0019] Compared with the related technology of controlling the start and stop of the heating tube by a fixed start and stop frequency, the method of adjusting the power of the electromagnetic coil by coordinating the current temperature value of the cavity and the first target temperature value is more flexible and reliable, which is conducive to reducing the temperature difference between the current temperature value and the first target temperature value, thereby solving the technical problem of large fluctuations in cavity temperature. At the same time, the control method defined in the present application can timely reduce the power of the electromagnetic coil when the current temperature value is greater than the first target temperature value, so as to reduce energy consumption on the basis of meeting the heating demand. Thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment.

[0020] In some technical solutions, optionally, the second power is less than the first power, or the second power is 0.

[0021] In this technical solution, the second power is less than the first power, that is, after the current temperature reaches the first target temperature value, the electromagnetic coil is controlled to operate at low power to reduce the heat generated by the magnetic component per unit time, thereby reducing the temperature rise of the magnetic component, so as to maintain the temperature of the magnetic component near the first target temperature value.

[0022] Alternatively, the second power is equal to zero, that is, after the current temperature reaches the first target temperature value, the electromagnetic coil is controlled to stop working to stop the heating of the magnetic conductive part, thereby reducing the temperature of the magnetic conductive part so as to maintain the temperature of the magnetic conductive part near the first target temperature value.

[0023] In some technical solutions, optionally, adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value includes:

[0024] Obtaining a second target value;

[0025] In response to the current temperature value being less than or equal to the first target temperature value and greater than or equal to the second target temperature value, the electromagnetic coil is controlled to operate at a third power.

[0026] In this technical solution, the steps of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value are refined. After the current temperature value of the cavity reaches the first target temperature value, the corresponding second target value is first determined according to the first target temperature value. Among them, the first target temperature value is greater than the second target value. After the electromagnetic coil stops working, the current temperature value of the cavity will rise to above the first target temperature value under the residual heat of the magnetic conductive part. Thereafter, the current temperature value gradually decreases with the cooling of the magnetic conductive part. The second target value is used to determine when to restart the electromagnetic coil. Thereafter, when the current temperature value drops to less than the first target temperature value and greater than or equal to the second target value, the electromagnetic coil is controlled to operate at a third power. The third power corresponds to the low power gear of the electromagnetic coil. Under the action of the electromagnetic coil of the third power, the decline of the current temperature value can be slowed down to maintain the current temperature value near the first target temperature value.

[0027] By controlling and adjusting the power of the electromagnetic coil through the above method, on the one hand, the current temperature value of the cavity can be combined with the follow-up control, thereby reducing the temperature difference between the current temperature value and the first target temperature value. On the other hand, the energy consumption of the electromagnetic coil can be reduced during the shutdown phase and the low-power phase. Thus, the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment is achieved.

[0028] In some technical solutions, optionally, the third power is greater than 0, and the third power is less than the first power.

[0029] In this technical solution, the third power is greater than 0 and less than the first power. The third power corresponds to the low power gear of the electromagnetic coil and the downward trend of the cavity temperature.

[0030] In some technical solutions, optionally, adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value includes:

[0031] Obtaining a second target value;

[0032] In response to the current temperature value being less than or equal to the second target temperature value, the electromagnetic coil is controlled to operate at a fourth power.

[0033] In this technical solution, the step of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value is refined.

[0034] In this technical solution, the steps of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value are refined. After the current temperature value of the cavity reaches the first target temperature value, the corresponding second target value is first determined according to the first target temperature value. Among them, the first target temperature value is greater than the second target value. After the electromagnetic coil stops working, the current temperature value of the cavity will rise to above the first target temperature value due to the residual heat of the magnetic conductive part, and then the current temperature value will gradually decrease with the cooling of the magnetic conductive part. The second target value is used to determine when to restart the electromagnetic coil.

[0035] Thereafter, when the current temperature value drops to less than the first target temperature value and greater than or equal to the second target value, the electromagnetic coil is controlled to operate at the third power, which corresponds to the low power gear of the electromagnetic coil. Under the action of the electromagnetic coil of the third power, the current temperature value can be slowed down, but the downward trend of the current temperature value will not be stopped. Until the current temperature value drops to less than the second target value, the electromagnetic coil is controlled to operate at the fourth power, which corresponds to the high power gear of the electromagnetic coil, and the current temperature value of the corresponding cavity changes from a downward trend to an upward trend. The subsequent cycle executes the step of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value to maintain the current temperature value near the first target temperature value.

[0036] The power of the electromagnetic coil is controlled and adjusted by the above method, so that the electromagnetic coil has three stages in a single cycle of operation: fast cooling after shutdown, slow cooling at low power, and temperature recovery at high power. Compared with the fixed frequency start-stop scheme in the related art, on the one hand, it can be combined with the current temperature value of the cavity for follow-up control, thereby reducing the temperature difference between the current temperature value and the first target temperature value. On the other hand, the energy consumption of the electromagnetic coil can be reduced through the shutdown stage and the low power stage. Thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment.

[0037] In some technical solutions, optionally, the fourth power is greater than or equal to the first power; and the fourth power is the maximum rated power of the electromagnetic coil.

[0038] In this technical solution, the fourth power is greater than the first power, or the fourth power corresponds to the full power position of the electromagnetic coil.

[0039] In some technical solutions, optionally, the second target value is the difference between the first target temperature value and the first preset temperature value; wherein the value range of the first preset temperature value is: greater than or equal to 5°C and less than or equal to 20°C.

[0040] In this technical solution, a first method of determining the second target value is proposed. Specifically, the preset temperature value is subtracted from the first target temperature value to calculate the second target value, wherein the preset temperature value is a constant. For example, the preset temperature value can be selected as 10°C, and the second target value = the first target temperature value - 10°C. Determining the second target value by the preset temperature value can simplify the control process of the hot air heating device, thereby achieving the technical effect of reducing the data processing burden of the hot air heating device and reducing the cost of the hot air heating device.

[0041] On this basis, the preset temperature value needs to be greater than or equal to 5°C and less than or equal to 20°C. By limiting the preset temperature value to be greater than or equal to 5°C, the duration of the low-power cooling phase can be extended while ensuring the heating demand, thereby reducing the energy consumption of the electromagnetic coil. By limiting the preset temperature value to be less than or equal to 20°C, the difference between the current temperature value and the first target temperature value can be avoided to be too large, thereby ensuring the heating effect.

[0042] In some technical solutions, optionally, the step of obtaining the second target value includes:

[0043] Acquire a second preset temperature value corresponding to the first target temperature value;

[0044] The second target value is determined according to the difference between the first target temperature value and the second preset temperature value.

[0045] In one possible implementation, the second target value may be associated with the magnitude of the first target temperature value. For example, the hot air heating device pre-stores a first temperature interval and a second temperature interval, the lower limit of the first temperature interval is greater than the upper limit of the second temperature interval, the second target value corresponding to the first temperature interval is larger, and the second target value corresponding to the second temperature interval is smaller, and the corresponding second target value is selected according to the interval into which the first target temperature value actually falls.

[0046] In one possible implementation, the corresponding second target value is determined according to the first target temperature value and the current working mode of the hot air heating device. For example, when the hot air heating device is a cooking device, a smaller second target value is selected in the high temperature baking mode, and a larger second target value is selected in the heat preservation stage. When the hot air heating device is a cleaning device, a smaller second target value is selected in the high temperature sterilization mode, and a larger second target value is selected in the drying mode.

[0047] By limiting the determination method of the above-mentioned second target value, the power of the electromagnetic coil can be associated with the size of the first target temperature value and the working requirements, thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment and improving the heating reliability of the hot air heating equipment.

[0048] In some technical solutions, optionally, the step of obtaining the first target temperature value includes:

[0049] Obtaining material information in the cavity;

[0050] A first target temperature value is determined according to the material information.

[0051] In this technical solution, the step of obtaining the first target temperature value is refined. Specifically, the hot air heating device first obtains the material information in the cavity.

[0052] In one possible implementation, the hot air heating device is provided with an image acquisition device, which can obtain image information in the cavity, and then determine the corresponding material information with the help of image recognition technology.

[0053] In one possible implementation, the user can input corresponding material information by operating the control panel or pressing buttons.

[0054] After obtaining the material information, the corresponding first target temperature value is determined according to the material information. The first target temperature value can be determined by the correspondence between the material type and the first target temperature value pre-stored in the hot air heating device, and can also be downloaded and obtained after uploading the material information to the server.

[0055] By limiting the above control method, the working state of the electromagnetic coil can be associated with the type of material to be heated, thereby ensuring that the hot air heating equipment can meet the heating requirements of the material to be heated, thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment and improving the practicality of the hot air heating equipment.

The high-temperature magnetic conductive part blows out a high-temperature airflow through rotation, and the high-temperature airflow acts on the cavity. The temperature sensor is set corresponding to the cavity, and the temperature sensor can detect the current temperature value of the cooking cavity.

[0060] On this basis, in the process of controlling the operation of the hot air heating device, the acquisition module first acquires the first target temperature value, which corresponds to the temperature value that the cooking cavity needs to reach. The specific value of the first target temperature value is related to the type of material to be heated and the function to be achieved. After acquiring the first target temperature value, the control module controls the electromagnetic coil to operate at the first power, and at the same time controls the rotation of the magnetic conductive part. The first power corresponds to the high power gear of the electromagnetic coil, and the highest gear can be selected specifically.

[0093] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0094] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0095] Refer to the following Figures 1 to 9 A hot air heating device and a control method, device and readable storage medium thereof according to some embodiments of the present invention are described.

[0096] like Figure 1 As shown, an embodiment of the present invention provides a control method for a hot air heating device, the hot air heating device includes a cavity, a temperature sensor, an electromagnetic coil and a magnetic conductive member, the temperature sensor is used to detect the current temperature value of the cavity, the electromagnetic coil is used to generate an electromagnetic field for heating the magnetic conductive member, and the control method of the hot air heating device includes:

[0097] Step 102, obtaining a first target temperature value;

[0098] Step 104, controlling the electromagnetic coil to operate at a first power to heat the magnetic conductive member;

[0099] Step 106: Adjust the power of the electromagnetic coil according to the first target temperature value and the current temperature value.

[0100] The present application defines a control method for a hot air heating device, which includes a cavity, a temperature sensor, an electromagnetic coil and a magnetic conductive member.

[0101] Specifically, the cavity is used to contain materials, and the materials are heated by high-temperature airflow in the cavity. When the hot air heating device is a cooking device such as an air fryer or an oven, the materials are food, and the food in the cavity is cooked into a finished product under the action of the high-temperature airflow. When the hot air heating device is a cleaning device such as a dishwasher or a disinfection cabinet, the materials are tableware, and the tableware in the cavity is dried and sterilized by the high-temperature airflow.

[0102] The electromagnetic coil and the magnetic conductive part are used together. The electromagnetic coil can generate an electromagnetic field. The magnetic conductive part heats up in the electromagnetic field. The high-temperature magnetic conductive part blows out a high-temperature airflow through rotation, and the high-temperature airflow acts on the cavity. The temperature sensor is set corresponding to the cavity, and the temperature sensor can detect the current temperature value of the cooking cavity.

[0103] On this basis, in the process of controlling the operation of the hot air heating device, the first target temperature value is first obtained. The target temperature value corresponds to the temperature value that the cooking cavity needs to reach. The specific value of the first target temperature value is related to the type of material to be heated and the function to be achieved. After obtaining the first target temperature value, the electromagnetic coil is controlled to operate at the first power, and the magnetic conductive part is controlled to rotate at the same time. The first power corresponds to the high power gear of the electromagnetic coil, and the highest gear can be selected specifically. Under the action of the electromagnetic coil operating at the first power, the magnetic conductive part heats up rapidly, and the first target temperature value in the corresponding cavity rises rapidly. In this process, the temperature sensor monitors the current temperature value of the cavity in real time, and adjusts the power of the electromagnetic coil according to the first target temperature value and the current temperature value to maintain the current temperature value of the cavity near the first target temperature value.

[0104] Compared with the related technology of controlling the start and stop of the heating tube by a fixed start and stop frequency, the method of adjusting the power of the electromagnetic coil by coordinating the current temperature value of the cavity and the first target temperature value is more flexible and reliable, which is conducive to reducing the temperature difference between the current temperature value and the first target temperature value, thereby solving the technical problem of large fluctuations in cavity temperature. At the same time, the control method defined in the present application can timely reduce the power of the electromagnetic coil when the current temperature value is greater than the first target temperature value, so as to reduce energy consumption on the basis of meeting the heating demand. Thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment.

[0105] In some embodiments, optionally, adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value includes: in response to the current temperature value being greater than or equal to the first target temperature value, controlling the electromagnetic coil to operate at a second power.

[0106] In this embodiment, in the process of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value, the magnetic conductive part heats up rapidly, and the first target temperature value in the corresponding cavity rises rapidly. In this process, the temperature sensor monitors the current temperature value of the cavity in real time, and when the current temperature value rises to the first target temperature value, the power of the electromagnetic coil is adjusted according to the first target temperature value and the current temperature value to maintain the current temperature value of the cavity near the first target temperature value.

[0107] Compared with the related technology of controlling the start and stop of the heating tube by a fixed start and stop frequency, the method of adjusting the power of the electromagnetic coil by coordinating the current temperature value of the cavity and the first target temperature value is more flexible and reliable, which is conducive to reducing the temperature difference between the current temperature value and the first target temperature value, thereby solving the technical problem of large fluctuations in cavity temperature. At the same time, the control method defined in the present application can timely reduce the power of the electromagnetic coil when the current temperature value is greater than the first target temperature value, so as to reduce energy consumption on the basis of meeting the heating demand. Thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment.

[0108] In some embodiments, optionally, the second power is less than the first power, or the second power is zero.

[0109] In this embodiment, the second power is less than the first power, that is, after the current temperature reaches the first target temperature value, the electromagnetic coil is controlled to operate at low power to reduce the heat generated by the magnetic component per unit time, thereby reducing the temperature rise of the magnetic component, so as to maintain the temperature of the magnetic component near the first target temperature value.

[0110] Alternatively, the second power is equal to zero, that is, after the current temperature reaches the first target temperature value, the electromagnetic coil is controlled to stop working to stop the heating of the magnetic conductive part, thereby reducing the temperature of the magnetic conductive part so as to maintain the temperature of the magnetic conductive part near the first target temperature value.

[0111] like Figure 2 As shown, in some embodiments, optionally, adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value includes:

[0112] Step 202, obtaining a second target value;

[0113] Step 204 , in response to the current temperature value being less than or equal to the first target temperature value and greater than or equal to the second target temperature value, controlling the electromagnetic coil to operate at a third power.

[0114] In this embodiment, the step of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value is refined. After the current temperature value of the cavity reaches the first target temperature value, the corresponding second target value is first determined according to the first target temperature value. Among them, the first target temperature value is greater than the second target value. After the electromagnetic coil stops working, the current temperature value of the cavity will rise to above the first target temperature value under the residual heat of the magnetic conductive part, and then the current temperature value will gradually decrease with the cooling of the magnetic conductive part. The second target value is used to determine when to restart the electromagnetic coil. Thereafter, when the current temperature value drops to less than the first target temperature value and greater than or equal to the second target value, the electromagnetic coil is controlled to operate at a third power. The third power corresponds to the low power gear of the electromagnetic coil. Under the action of the electromagnetic coil of the third power, the decline of the current temperature value can be slowed down to maintain the current temperature value near the first target temperature value.

[0115] By controlling and adjusting the power of the electromagnetic coil through the above method, on the one hand, the current temperature value of the cavity can be combined with the follow-up control, thereby reducing the temperature difference between the current temperature value and the first target temperature value. On the other hand, the energy consumption of the electromagnetic coil can be reduced during the shutdown phase and the low-power phase. Thus, the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment is achieved.

[0116] In some embodiments, optionally, the third power is greater than 0, and the third power is less than the first power.

[0117] In this embodiment, the third power is greater than 0 and less than the first power. The third power corresponds to a low power gear of the electromagnetic coil and a decreasing trend of the cavity temperature.

[0118] like Figure 3 As shown, in some embodiments, optionally, adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value includes:

[0119] Step 302, obtaining a second target value;

[0120] Step 304 : In response to the current temperature value being less than or equal to the second target temperature value, controlling the electromagnetic coil to operate at a fourth power.

[0121] In this embodiment, the step of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value is refined.

[0122] In this embodiment, the step of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value is refined. After the current temperature value of the cavity reaches the first target temperature value, the corresponding second target value is first determined according to the first target temperature value. Among them, the first target temperature value is greater than the second target value. After the electromagnetic coil stops working, the current temperature value of the cavity will rise to above the first target temperature value due to the residual heat of the magnetic conductive part, and then the current temperature value will gradually decrease as the magnetic conductive part cools down. The second target value is used to determine when to restart the electromagnetic coil.

[0123] Thereafter, when the current temperature value drops to less than the first target temperature value and greater than or equal to the second target value, the electromagnetic coil is controlled to operate at the third power, which corresponds to the low power gear of the electromagnetic coil. Under the action of the electromagnetic coil of the third power, the current temperature value can be slowed down, but the downward trend of the current temperature value will not be stopped. Until the current temperature value drops to less than the second target value, the electromagnetic coil is controlled to operate at the fourth power, which corresponds to the high power gear of the electromagnetic coil, and the current temperature value of the corresponding cavity changes from a downward trend to an upward trend. The subsequent cycle executes the step of adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value to maintain the current temperature value near the first target temperature value.

[0124] The power of the electromagnetic coil is controlled and adjusted by the above method, so that the electromagnetic coil has three stages in a single cycle of operation: fast cooling after shutdown, slow cooling at low power, and temperature recovery at high power. Compared with the fixed frequency start-stop scheme in the related art, on the one hand, it can be combined with the current temperature value of the cavity for follow-up control, thereby reducing the temperature difference between the current temperature value and the first target temperature value. On the other hand, the energy consumption of the electromagnetic coil can be reduced through the shutdown stage and the low power stage. Thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment.

[0125] like Fig. 9 As shown, when the first target temperature value is selected as 200° C., in the related art of controlling the heating element to start and stop at fixed intervals, the actual temperature value fluctuates up to 250° C. However, in the technical solution defined in the present application, the fluctuation range is relatively small.

[0126] In some embodiments, optionally, the fourth power is greater than or equal to the first power; and the fourth power is the maximum rated power of the electromagnetic coil.

[0127] In this embodiment, the fourth power is greater than the first power, or the fourth power corresponds to the full power position of the electromagnetic coil.

[0128] In some embodiments, optionally, the second target value is the difference between the first target temperature value and the first preset temperature value; wherein the value range of the first preset temperature value is: greater than or equal to 5°C and less than or equal to 20°C.

[0129] In this embodiment, a first method of determining the second target value is proposed. Specifically, the preset temperature value is subtracted from the first target temperature value to calculate the second target value, wherein the preset temperature value is a constant. For example, the preset temperature value can be selected as 10°C, and the second target value = the first target temperature value - 10°C. Determining the second target value by the preset temperature value can simplify the control process of the hot air heating device, thereby achieving the technical effect of reducing the data processing burden of the hot air heating device and reducing the cost of the hot air heating device.

[0130] On this basis, the preset temperature value needs to be greater than or equal to 5°C and less than or equal to 20°C. By limiting the preset temperature value to be greater than or equal to 5°C, the duration of the low-power cooling phase can be extended while ensuring the heating demand, thereby reducing the energy consumption of the electromagnetic coil. By limiting the preset temperature value to be less than or equal to 20°C, the difference between the current temperature value and the first target temperature value can be avoided to be too large, thereby ensuring the heating effect.

[0131] like Figure 4 As shown, in some embodiments, optionally, the step of obtaining the second target value includes:

[0132] Step 402, obtaining a second preset temperature value corresponding to the first target temperature value;

[0133] Step 404: determine a second target value according to a difference between the first target temperature value and the second preset temperature value.

[0134] In one possible implementation, the second target value may be associated with the magnitude of the first target temperature value. For example, the hot air heating device pre-stores a first temperature interval and a second temperature interval, the lower limit of the first temperature interval is greater than the upper limit of the second temperature interval, the second target value corresponding to the first temperature interval is larger, and the second target value corresponding to the second temperature interval is smaller, and the corresponding second target value is selected according to the interval into which the first target temperature value actually falls.

[0135] In one possible implementation, the corresponding second target value is determined according to the first target temperature value and the current working mode of the hot air heating device. For example, when the hot air heating device is a cooking device, a smaller second target value is selected in the high temperature baking mode, and a larger second target value is selected in the heat preservation stage. When the hot air heating device is a cleaning device, a smaller second target value is selected in the high temperature sterilization mode, and a larger second target value is selected in the drying mode.

[0136] By limiting the determination method of the above-mentioned second target value, the power of the electromagnetic coil can be associated with the size of the first target temperature value and the working requirements, thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment and improving the heating reliability of the hot air heating equipment.

[0137] like Figure 5 As shown, in some embodiments, optionally, the step of obtaining the first target temperature value includes:

[0138] Step 502, obtaining material information in the cavity;

[0139] Step 504: determine a first target temperature value according to the material information.

[0140] In this embodiment, the step of obtaining the first target temperature value is refined. Specifically, the hot air heating device first obtains the material information in the cavity.

[0141] In one possible implementation, the hot air heating device is provided with an image acquisition device, which can obtain image information in the cavity, and then determine the corresponding material information with the help of image recognition technology.

[0142] In one possible implementation, the user can input corresponding material information by operating the control panel or pressing buttons.

[0143] After obtaining the material information, the corresponding first target temperature value is determined according to the material information. The first target temperature value can be determined by the correspondence between the material type and the first target temperature value pre-stored in the hot air heating device, and can also be downloaded and obtained after uploading the material information to the server.

[0144] By limiting the above control method, the working state of the electromagnetic coil can be associated with the type of material to be heated, thereby ensuring that the hot air heating equipment can meet the heating requirements of the material to be heated, thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment and improving the practicality of the hot air heating equipment.

[0145] like Figure 6 As shown, an embodiment of the present invention provides a control device 600 for a hot air heating device, the hot air heating device includes a cavity, a temperature sensor, an electromagnetic coil and a magnetic conductive part, the temperature sensor is used to detect the current temperature value of the cavity, the electromagnetic coil is used to generate an electromagnetic field for heating the magnetic conductive part, the control device 600 for the hot air heating device includes: an acquisition module 602, used to acquire a first target temperature value; a control module 604, used to control the electromagnetic coil to operate at a first power to make the magnetic conductive part heat up; an adjustment module 606, adjusting the power of the electromagnetic coil according to the first target temperature value and the current temperature value.

[0146] The present application defines a control device 600 for a hot air heating device, where the hot air heating device includes a cavity, a temperature sensor, an electromagnetic coil, and a magnetic conductive member.

[0147] Specifically, the cavity is used to contain materials, and the materials are heated by high-temperature airflow in the cavity. When the hot air heating device is a cooking device such as an air fryer or an oven, the materials are food, and the food in the cavity is cooked into a finished product under the action of the high-temperature airflow. When the hot air heating device is a cleaning device such as a dishwasher or a disinfection cabinet, the materials are tableware, and the tableware in the cavity is dried and sterilized by the high-temperature airflow.

[0148] The electromagnetic coil and the magnetic conductive part are used together. The electromagnetic coil can generate an electromagnetic field. The magnetic conductive part heats up in the electromagnetic field. The high-temperature magnetic conductive part blows out a high-temperature airflow through rotation, and the high-temperature airflow acts on the cavity. The temperature sensor is set corresponding to the cavity, and the temperature sensor can detect the current temperature value of the cooking cavity.

[0149] On this basis, in the process of controlling the operation of the hot air heating device, the acquisition module 602 first acquires the first target temperature value, which corresponds to the temperature value that the cooking cavity needs to reach. The specific value of the first target temperature value is associated with the type of material to be heated and the function to be realized. After acquiring the first target temperature value, the control module 604 controls the electromagnetic coil to operate at the first power and controls the rotation of the magnetic member at the same time. The first power corresponds to the high power gear of the electromagnetic coil, and the highest gear can be selected specifically. Under the action of the electromagnetic coil operating at the first power, the magnetic member heats up rapidly, and the first target temperature value in the corresponding cavity rises rapidly. In this process, the temperature sensor monitors the current temperature value of the cavity in real time, and the adjustment module 606 adjusts the power of the electromagnetic coil according to the first target temperature value and the current temperature value to maintain the current temperature value of the cavity near the first target temperature value.

[0150] Compared with the related technology of controlling the start and stop of the heating tube by fixing the start and stop frequency, the method of adjusting the power of the electromagnetic coil by coordinating the current temperature value of the cavity and the first target temperature value is more flexible and reliable, which is conducive to reducing the temperature difference between the current temperature value and the first target temperature value, thereby solving the technical problem of large fluctuations in cavity temperature. At the same time, the control device defined in the present application can timely reduce the power of the electromagnetic coil when the current temperature value is greater than the first target temperature value, so as to reduce energy consumption on the basis of meeting the heating demand. Thereby achieving the technical effect of improving the control accuracy of the hot air heating equipment, improving the heating effect of the hot air heating equipment, and reducing the energy consumption of the hot air heating equipment.
