The following describes the microwave heating control method, the microwave heating apparatus, and the computer storage medium provided in the present application in detail with reference to the embodiments.

The present application first provides a microwave heating control method for a microwave heating device, as shown in fig. 1, where fig. 1 is a schematic flow chart of an embodiment of the microwave heating control method. The microwave heating control method of the embodiment specifically includes the following steps:

step S11: the preset heating temperature profile of the heated object is determined based on the information of the heated object.

The information on the object to be heated may include information on the type and/or weight of the object to be heated. Because different types of heated objects have different heating rates and required heating temperatures in the heating process, and different weights of the heated objects of the same type have different heating rates in the heating process, the present embodiment may set different preset heating temperature curves for the heated objects of different types and/or different weights, so as to enable the heating power of the microwave heating of the heated objects, that is, the heating power of the microwave mechanism in the microwave heating device, to be adjusted according to the preset heating temperature curves corresponding to the types and/or weights of the heated objects in the following process.

Alternatively, before step S11 is executed, information of the heated object may also be acquired; for example, the type of the object to be heated may be acquired by an image recognition mechanism of the microwave heating device, and the weight of the object to be heated may be acquired by a pressure sensor of the microwave heating device. Of course, in other embodiments, the microwave heating device may also directly obtain information such as the type and/or weight of the heated object through the input mechanism.

The control means of the microwave heating device acquires information on the object to be heated, and acquires a preset heating temperature profile corresponding to the information on the object to be heated from among a plurality of preset heating temperature profiles as a preset heating temperature profile for the object to be heated.

Step S12: in the process of microwave heating of an object to be heated, the temperature of the object to be heated and a heating time period corresponding to the temperature are acquired.

The control mechanism controls the microwave mechanism of the microwave heating device to generate microwaves so as to heat the heated object by the microwaves.

The microwave mechanism of the present embodiment is a microwave solid-state source, and includes a controller and a signal generator connected to the controller, the controller is further connected to the control mechanism, the controller generates a heating instruction under the control of the control mechanism, and the signal generator generates a microwave signal based on the heating instruction to heat an object to be heated.

The microwave heating device of the embodiment adopts the microwave solid-state source to generate the microwave signal, and can realize stepless frequency modulation, so that each working frequency range of the microwave heating device can be smoothly adjusted. For example, the difference between the frequency bands of adjacent gears of the microwave heating device such as a microwave oven is small, and the embodiment adopts the microwave solid-state source to control the output power of the microwave signal, so that the adjustment between the frequency bands with the small difference can be realized.

For a detailed description of the microwave heating device and its microwave solid-state source, reference may be made to the following.

In other embodiments, the execution sequence of the control mechanism acquiring the preset heating temperature curve of the heated object and the execution sequence of the control mechanism controlling the microwave mechanism to heat the heated object may not be limited.

The control mechanism controls the microwave mechanism to start microwave heating of the object, and controls the timer to start timing so as to obtain the heating time length for microwave heating of the object.

In the process of microwave heating of the heated object by the microwave mechanism, the control mechanism controls the temperature measuring mechanism of the microwave device to acquire the temperature of the heated object and acquires the heating time length corresponding to the acquisition time of the temperature (namely, the timing time length cut off from the sampling time). The temperature may be a surface temperature of the heated object, such as a temperature of a certain point on the surface of the heated object, or a weighted value of temperatures of a plurality of points on the surface of the heated object, and the weight coefficients of the temperatures of the plurality of points may be the same or different. In other embodiments, the temperature may also be the internal temperature of the heated object, or the like.

Alternatively, step S12 may be implemented by a method as shown in fig. 2, and the method of this embodiment includes step S21 and step S22.

Step S21: in the process of microwave heating of the heated object, the current temperature and the current heating time length of the heated object corresponding to the current sampling time are acquired.

In the whole microwave heating process, the control mechanism can control the temperature measuring mechanism to obtain the temperature of the heated object at a series of sampling moments and obtain the heating time length corresponding to each sampling moment.

The temperature of the heated object acquired by the control mechanism at the current sampling moment is the current temperature, and the heating duration corresponding to the current sampling moment, namely the duration between the heating starting moment of the microwave mechanism and the current sampling moment is the current heating duration.

Step S22: and acquiring the previous temperature and the previous heating time length of the heated object corresponding to the previous sampling time of the current sampling time.

The temperature of the heated object acquired by the control mechanism at the sampling moment before the current sampling moment is the previous temperature, and the heating time length corresponding to the previous sampling moment, namely the time length between the heating starting moment and the previous sampling moment of the microwave mechanism is the previous heating time length.

The previous temperature and the previous heating time period of the object to be heated corresponding to the previous sampling time before the current sampling time are already collected and generated at the previous sampling time, and the acquisition of these pieces of information in step S22 means that the control means acquires these pieces of information from the memory to perform the following correlation calculation.

Step S13: and matching the temperature and the heating time with a preset heating temperature curve, and adjusting the heating power for performing microwave heating on the heated object based on the matching result.

The control mechanism matches the temperature and the corresponding heating time length of the heated object with a preset heating temperature curve of the heated object, and adjusts the heating power for microwave heating of the heated object based on the matching result so as to adjust the heating temperature of the heated object, so that the actual heating temperature curve of the heated object more conforms to the preset heating temperature curve.

The embodiment adjusts the heating power for microwave heating of the heated object by utilizing the matching result between the temperature and the heating time of the heated object and the preset heating temperature curve of the heated object in the microwave heating process, so that the actual heating temperature curve of the heated object more conforms to the preset heating temperature curve, namely more conforms to the preset or ideal heating temperature curve, the waste of microwave energy can be reduced, the microwave heating effect is improved, and the microwave heating efficiency can be improved.

Alternatively, step S13 may be implemented by a method as shown in fig. 3, and the method of the present embodiment includes step S31 to step S33.

Step S31: the current temperature change rate of the heated object is calculated based on the temperature and the heating time period.

The present embodiment can calculate the current temperature change rate of the object to be heated based on the current temperature, the previous temperature, the current heating time period, and the previous heating time period of the object to be heated. Specifically, the current temperature change rate is a ratio of a difference between the current temperature and the previous temperature to a difference between the current heating time period and the previous heating time period.

Step S32: and calculating a preset temperature change rate corresponding to the heating time length based on the preset heating temperature curve.

Specifically, a current preset temperature corresponding to the current heating time and a previous preset temperature corresponding to the previous heating time may be obtained from a preset heating temperature curve, and then a ratio of a difference between the current preset temperature and the previous preset temperature to a difference between the current heating time and the previous heating time is calculated as a preset temperature change rate

Step S33: and matching the current temperature change rate with a preset temperature change rate, and adjusting the heating power of the microwave heating based on the matching result.

Optionally, in response to the current temperature change rate being greater than the preset temperature change rate, reducing the heating power for microwave heating of the heated object; and increasing the heating power for performing microwave heating on the heated object in response to the current temperature change rate being less than the preset temperature change rate.

If the current temperature change rate of the heated object is greater than the preset temperature change rate, the current temperature rise of the heated object can be considered to be too fast, and the control mechanism reduces the heating power of the microwave mechanism so as to reduce the heating power for microwave heating of the heated object, thereby reducing the temperature rise rate of the heated object; if the current temperature change rate of the heated object is less than the preset temperature change rate, the current temperature rise of the heated object can be considered to be too slow, and the control mechanism increases the heating power of the microwave mechanism to increase the heating power for microwave heating of the heated object, so that the temperature rise rate of the heated object is increased; if the current temperature change rate of the heated object is equal to the preset temperature change rate, the current temperature rise of the heated object can be considered to be moderate, and the control mechanism does not need to adjust the heating power of the microwave mechanism; in this way, the actual heating temperature profile of the heated object can be made to more closely conform to its preset heating temperature profile.

In another embodiment, step S33 may be implemented by a method as shown in fig. 4, and the method of the present embodiment includes steps S41 to S43.

Step S41: a difference between the current temperature change rate and a preset temperature change rate is calculated.

Step S42: in response to the difference being greater than a first preset difference, reducing the heating power for microwave heating of the heated object; wherein the first predetermined difference is greater than zero.

Step S43: in response to the difference being smaller than a second preset difference, increasing the heating power for microwave heating of the heated object; wherein the second predetermined difference is less than zero.

If the difference value between the current temperature change rate of the heated object and the preset temperature change rate is larger than the first preset difference value, the current temperature rise of the heated object can be considered to be too fast, and the control mechanism reduces the heating power of the microwave mechanism so as to reduce the heating power for microwave heating of the heated object, thereby reducing the temperature rise rate of the heated object; if the difference value between the current temperature change rate and the preset temperature change rate of the heated object is smaller than the second preset difference value, the current temperature rise of the heated object can be considered to be too slow, and the control mechanism increases the heating power of the microwave mechanism to increase the heating power for microwave heating of the heated object, so that the temperature rise rate of the heated object is increased; if the difference value between the current temperature change rate of the heated object and the preset temperature change rate is greater than or equal to a second preset difference value or is less than or equal to a first preset difference value, the current temperature rise of the heated object can be considered to be moderate, and the control mechanism does not need to adjust the heating power of the microwave mechanism; in this way, the actual heating temperature profile of the heated object can be made to more closely conform to its preset heating temperature profile.

In the embodiment, margin design is performed on the temperature change rate, that is, the difference value, so that the problem of frequent adjustment of the output power can be solved.

The present application further provides a microwave heating control method according to another embodiment, as shown in fig. 5, fig. 5 is a schematic flowchart of an embodiment of the microwave heating control method according to the present application. The microwave heating control method of the embodiment specifically includes the following steps:

step S51: the preset heating temperature profile of the heated object is determined based on the information of the heated object.

Reference may be made to the above examples for specific embodiments.

Step S52: in the process of microwave heating of an object to be heated, the temperature of the object to be heated and a heating time period corresponding to the temperature are acquired.

Reference may be made to the above examples for specific embodiments.

Step S53: and matching the temperature and the heating time with a preset heating temperature curve, and adjusting the heating power for performing microwave heating on the heated object based on the matching result.

Reference may be made to the above examples for specific embodiments.

Step S54: the actual output power for microwave heating of the object to be heated is obtained.

The control mechanism controls a power detection circuit of the microwave heating device to obtain the actual output power of the microwave mechanism.

Step S55: and matching the actual output power with the heating power, and adjusting the heating power based on the matching result.

Because various interference factors exist, the heating power of the microwave mechanism controlled by the control mechanism may have a certain deviation from the actual output power of the microwave mechanism, and therefore, in order to reduce the deviation, the present embodiment obtains the actual output power of the microwave mechanism, and adjusts the heating power of the microwave mechanism based on the matching result between the actual output power and the heating power of the microwave mechanism controlled by the control mechanism, so that the actual output power of the microwave mechanism is consistent with the heating power of the microwave mechanism.

Specifically, in response to the actual output power being greater than the heating power, the heating power is reduced; in response to the actual output power being less than the heating power, the heating power is increased.

If the actual output power of the microwave mechanism is greater than the heating power, the actual output power of the microwave mechanism is considered to be larger due to the interference factor, and the control mechanism reduces the heating power of the microwave mechanism so as to reduce the actual output power of the microwave mechanism; if the actual output power of the microwave mechanism is smaller than the heating power, the actual output power of the microwave mechanism is considered to be smaller due to the existence of interference factors, and the control mechanism increases the heating power of the microwave mechanism so as to increase the actual output power of the microwave mechanism; if the actual output power of the microwave mechanism is equal to the heating power, the actual output power of the microwave mechanism has no deviation, and the control mechanism does not adjust the heating power of the microwave mechanism.

In other embodiments, the execution sequence between the power detection circuit acquiring the actual output power of the microwave mechanism and the temperature detection mechanism acquiring the temperature of the heated object is not limited.

The information on the object to be heated may include information on the type and/or weight of the object to be heated. Since the heating rates of the different types of heated objects in the heating process and the required heating temperatures are different, and the heating rates of the different types of heated objects with different weights in the heating process are also different, the present embodiment may set different preset heating temperature curves for the different types and/or different weights of heated objects, so that the heating power of the microwave heating of the heated objects, that is, the heating power of the microwave mechanism 61, can be adjusted according to the preset heating temperature curves corresponding to the types and/or weights of the heated objects.

In the process of microwave heating of the object to be heated by the microwave mechanism 61, the control mechanism 63 controls the temperature measuring mechanism 62 to obtain the temperature of the object to be heated, and obtains the heating time period corresponding to the sampling timing of the temperature (i.e., the time period counted up to the sampling timing). The temperature may be a surface temperature of the heated object, such as a temperature of a certain point on the surface of the heated object, or a weighted value of temperatures of a plurality of points on the surface of the heated object, and the weight coefficients of the temperatures of the plurality of points may be the same or different. In other embodiments, the temperature may also be the internal temperature of the heated object, or the like.

The microwave heating apparatus of the present embodiment is provided with a heating chamber 64 in which an object to be heated is placed, a microwave mechanism 61 communicating with the heating chamber 64 to transmit a microwave signal to the heating chamber 64 to microwave-heat the object to be heated in the heating chamber 64; the temperature measuring mechanism is provided in the heating chamber 64 and is used for acquiring the temperature of the heated object in the heating chamber 64, or acquiring the temperature in the heating chamber 64 as the temperature of the heated object, and the like.

According to the embodiment, the heating power for microwave heating of the heated object is adjusted by utilizing the matching result between the temperature and the heating time of the heated object and the preset heating temperature curve of the heated object in the microwave heating process, so that the actual heating temperature curve of the heated object is more consistent with the preset heating temperature curve, namely the actual heating temperature curve is more consistent with the preset heating temperature curve, namely the ideal heating temperature curve, the waste of microwave energy can be reduced, the microwave heating effect is improved, and the microwave heating efficiency can be improved.
