[0002] Thawing technology is widely used. During the thawing process, the temperature of the food to be thawed is constantly changing, which causes the impedance of the food to be thawed to change continuously, and the absorbed power of the food to be thawed is also changing. In the absence of a matching impedance network of a tuned circuit, the fixed frequency method can no longer meet the requirements of the radio frequency working at the best output, resulting in a poor thawing effect on the food to be thawed.

[0057] Radio frequency thawing technology is widely used in different electrical equipment, mainly used for thawing food to be thawed. Taking radio frequency thawing as an example, the application of radio frequency thawing technology is introduced. The radio frequency thawing device includes a radio frequency generating component 150 and a tuning module 120. The radio frequency generating component 150 includes a power module 152, a power amplifier module 154 and a control module 156. The power module 152, the power amplifier module 154 and the control module 156 are all electrically connected. The power module 152 is used to supply power to the power amplifier module 154 and the control module 156. The power amplifier module 154 is used to generate an initial signal of a set frequency. The control module 156 is used to control the operation of the circuits in the power module 152 and the power amplifier module 154. When the output power of the power amplifier module 154 needs to be adjusted, the control module 156 calculates a voltage adjustment control instruction based on an internal algorithm and sends it to the power module 152. The power module 152 adjusts the voltage to change the output voltage of the power module 152.

[0058] The power amplifier module 154 includes a signal source 154a, a power amplifier circuit 154b and a detection circuit 154c. The signal source 154a is used to generate an initial signal of a set frequency (40.68MHz); the power amplifier circuit 154b is used to amplify the power of the initial signal, enhance the power of the initial signal, and output a power amplifier signal; the detection circuit 154c is used to detect the output power of the power amplifier signal and detect the reflected power reflected back from the tuning module 120, and feed it back to the control module 156.

[0059] The tuning module 120 includes a tuning inductor 140 and a plate 130 , which are electrically connected to each other and to the power amplifier module 154 through the tuning inductor 140 . After receiving the power amplifier signal, the tuning module 120 radiates radio frequency energy to the food to quickly thaw the food.

[0060] In the process of thawing the items to be thawed, the items to be thawed are mainly thawed by absorbing the power radiated by the plates. The more power the items to be thawed absorb, the smaller the thawing effect. The reflected power is equal to the total power radiated by the plates minus the power absorbed by the food to be thawed. In other words, the greater the reflected power, the smaller the power absorbed by the items to be thawed, and the smaller the reflected power, the more power absorbed by the items to be thawed. The reflected power can intuitively reflect the thawing effect of the items to be thawed.

[0061] The absorbed power of the items to be thawed is related to the impedance of the items to be thawed. During the thawing process, the temperature of the food to be thawed is constantly changing, which causes the impedance of the food to be thawed to constantly change, and the absorbed power of the items to be thawed is also changing. In the absence of a matching impedance network of a tuned circuit, the fixed frequency method can no longer meet the requirements of the radio frequency working at the best output, resulting in a poor thawing effect on the items to be thawed.

[0062] In the related art, the impedance of the items to be thawed can be matched by adjusting the matching impedance network or adjusting the set frequency. Although there are many methods for adjusting the set frequency, most of them require re-matching in the database, but the matching process of the set frequency takes a long time and the workload is large. The radio frequency thawing method, device, radio frequency thawing device, refrigerator and storage medium provided in the embodiments of the present application can improve the above problems. The radio frequency thawing control method, device, radio frequency thawing device, refrigerator and storage medium provided in the embodiments of the present application can improve the matching efficiency of the operating frequency during the radio frequency thawing process, shorten the matching time, and reduce the risk in the matching process to a certain extent.

[0063] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0064] See also Figure 2 The embodiment of the present application provides a radio frequency thawing control method. The radio frequency thawing control method provided by the embodiment of the present application can improve the matching efficiency of the operating frequency during the radio frequency thawing process, shorten the matching time, and reduce the risk in the matching process to a certain extent.

[0065] In the embodiment of the present application, the specific steps of the radio frequency thawing control method are as follows:

[0066] Step S100: obtaining a reference data set from a preset database.

[0067] The preset database includes multiple set frequencies, and the multiple set frequencies in the preset database basically include the optimal frequencies of all types of items to be thawed in different thawing stages in daily life. That is to say, in the thawing process, no matter what type of items to be thawed, at any stage, the corresponding set frequency can be matched in the preset database as the optimal frequency of the items to be thawed at the current moment.

[0068] Among them, the preset database includes a benchmark data group and other data groups, the benchmark data group and other data groups each include multiple set frequencies, and the reflected power corresponding to any set frequency in the benchmark data group is smaller than the reflected power corresponding to any set frequency in the other data groups.

[0069] Other data groups refer to all other set frequencies in the preset database except for the benchmark data group. If the reflected power corresponding to all set frequencies in the benchmark data group is less than the reflected power corresponding to all set frequencies in other data groups, it means that the set frequency of the benchmark data group is the most consistent with the thawing state of the to-be-thawed items in the entire preset database at the current moment. Firstly matching the benchmark data group from the preset database, and then matching the best frequency at that moment from the benchmark data group can reduce the matching workload and improve the matching efficiency.

[0070] By obtaining a reference data set from a preset database, a set frequency that is more suitable for the items to be thawed at the current moment can be selected from multiple set frequencies in the preset database in advance. Firstly matching a reference data set from the preset database, and then matching the best frequency at the current moment from the reference data set can reduce the workload of matching and improve matching efficiency. Specifically, the following will introduce in detail how to obtain a reference data set from a preset database.

[0071] See also Figure 3 , wherein step S100 may include step S110 and step S120.

[0072] Step S110, obtaining a reference frequency from a frequency array.

[0073] The set frequencies in the preset database are arranged in a matrix in order of size to obtain a frequency array, wherein in the frequency array, among the multiple set frequencies in the same row, the values ​​of the set frequencies increase from left to right, that is, the multiple set frequencies from left to right are arranged in order from small to large. Among the multiple set frequencies in the same column, the values ​​of the set frequencies increase from bottom to top, that is, the multiple set frequencies from bottom to top are arranged in order from small to large.

[0074] For example: In the same column, the set frequency at the bottom is smaller than the set frequency at the top. In the same row, the set frequency at the left is smaller than the set frequency at the right. In different columns, all the set frequencies at the left column are smaller than all the set frequencies at the right column. In different rows, all the set frequencies at the bottom row are smaller than all the set frequencies at the top row.

[0075] In other words, in the frequency array, the multiple set frequencies in the same row are continuous in size, while the multiple set frequencies in the same column are jumpy in size. It can be considered that the size relationship of the multiple set frequencies in the same column is arranged in an arithmetic progression.

[0076] It should be noted that the above only lists one arrangement of the frequency array. In addition, the frequency array can also have other arrangements, which can be that multiple set frequencies in the same row increase from right to left, or multiple set frequencies in the same column increase from top to bottom. It can also be that the multiple set frequencies in the same column are continuous in size, and the multiple set frequencies in the same row are arranged in an arithmetic progression. When the frequency array is arranged in other ways, it can be deduced by analogy.

[0077] Arrange the multiple set frequencies in the preset database in a matrix so that the multiple set frequencies in the preset database are arranged in order according to the magnitude relationship. The reference database can be obtained from the frequency array or a reference frequency first, and then through the reference frequency.

[0078] Arrange multiple set frequencies in the preset database according to a size relationship matrix, and then obtain a reference frequency in the frequency array. The size relationship of the frequency array can be used to reduce the time for matching the reference frequency and improve the matching efficiency.

[0079] See also Figure 4 and Figure 5 , wherein step S110 may include step S112a, step S112b and step S112c or include step S114.

[0080] Specifically, the embodiment of the present application provides two methods for obtaining the reference frequency from the frequency array, wherein step S112a, step S112b and step S112c provide one method for obtaining, and step S114 provides another method for obtaining.

[0081] Step S112a, obtaining the target column in the frequency array.

[0082] In some embodiments, multiple set frequencies in the preset database are arranged in a matrix manner, and the sizes of the multiple set frequencies in the same column are arranged in an arithmetic progression. One of the columns can be first obtained from the frequency array as the target column, that is, the sizes of all the set frequency quality checks in the target column are discontinuous, and the multiple set frequencies in the target column can be used to match the reference frequency.

[0083] The rightmost column in the frequency array may be used as the target column, that is, all set frequencies in the target column are the maximum set frequencies in the row.

[0084] Step S112b, determining the initial reflected power corresponding to each set frequency in the target column to obtain an initial power group.

[0085] After obtaining the target column, each set frequency in the target column is brought into the device to obtain the initial reflected power when the items to be thawed are thawed at the set frequency at the current moment. Since there are multiple set frequencies, there are also multiple initial reflected powers, and multiple initial reflected powers constitute an initial power group.

[0086] Step S112c: setting the set frequency corresponding to the minimum initial reflected power in the initial power group as the reference frequency.

[0087] Among the multiple set frequencies of the target column, multiple initial reflected powers are obtained. Among the multiple set frequencies of the target column, the set frequency with the smallest initial reflected power indicates that the set frequency in the target column is most consistent with the current state of the object to be thawed, and the set frequency is used as the reference frequency.

[0088] In the above process, in the process of matching the reference frequency, the target column is first obtained from the frequency array, and then the reference frequency is matched from the target column, that is, the reference frequency is directly matched from the preset database. The above method is applicable to the case where there is no reference in the initial state. Of course, the above situation can also be applied to the intermediate state. In addition, the method in step S114 can also be used at the intermediate moment, as follows.

[0089] Step S114: taking the operating frequency at the last moment as the current reference frequency.

[0090] Since the states of the items to be thawed are not much different at two adjacent moments, the operating frequency at the previous moment can be directly used as the reference frequency at the current moment, which can reduce the steps of obtaining the reference frequency, thereby shortening the matching time of the reference frequency at the current moment and improving the matching efficiency.

[0091] The operating frequency at the last moment refers to the best frequency at the last moment, that is, the set frequency with the smallest reflected power among all the set frequencies in the preset database at the last moment.

[0092] See also Figure 3 , step S120, obtaining the reference frequency and all the set frequencies around it as a reference data group.

[0093] The multiple set frequencies in the preset database are arranged in a matrix in order of size, that is, the set frequencies around the base frequency are not much different from the base frequency in value. Since the base frequency is the best frequency among the multiple set frequencies in the target column, the best frequency of the items to be thawed at the current moment is around the base frequency. The base frequency and all the set frequencies around it are taken as the base data group, and all the set frequencies in the base data group basically include the best frequency of the items to be thawed at the current moment.

[0094] That is, the reference frequency and all the set frequencies around it can be obtained as the reference data group. Specifically, how to obtain all the set frequencies around the reference frequency will be described in detail below.

[0095] See also Figure 6 , wherein step S120 may include step S122 and step S124.

[0096] Step S122, determining the row where the reference frequency is located and the adjacent rows.

[0097] The row where the reference frequency is located refers to the row where the reference frequency is located, and the adjacent rows refer to the row above the reference frequency and the row below the reference frequency. The sizes of all the set frequencies of the row where the reference frequency is located and the adjacent rows of the frequency array are continuous. After obtaining the reference frequency, determining the row where the reference frequency is located and the adjacent rows can facilitate obtaining the reference data group.

[0098] Step S124: All the set frequencies in the row where the reference frequency is located and in the adjacent rows are used as a reference data group.

[0099] Since the sizes of all the set frequencies in the row where the reference frequency is located and the adjacent rows are continuous, and the set frequency in the upper row is greater than the reference frequency, and the set frequency in the lower row is less than the reference frequency, the sizes of all the set frequencies in the row where the reference frequency is located and the adjacent rows are basically around the reference frequency, so that all the set frequencies in the reference data group basically include the optimal frequency of the items to be thawed at the current moment.

[0100] See also Figure 2 , step S200, determining the reference reflected powers corresponding to multiple set frequencies in the reference data group to obtain a reference power group.

[0101] After obtaining the reference data group, the corresponding reflected power of the item to be thawed at each set frequency at the current moment is determined to obtain the reference reflected power. Since each set frequency corresponds to a reference reflected power, multiple set frequencies correspond to multiple reference reflected powers, and multiple reference reflected powers form a reference power group.

[0102] Step S300: setting a set frequency corresponding to the minimum reference reflected power in the reference power group as the operating frequency.

[0103] The set frequencies in the reference data group are all the set frequencies in the preset database that are more consistent with the state of the items to be thawed at the current moment. The set frequency corresponding to the minimum reference reflected power in the reference power group is the set frequency with the minimum reflected power of the items to be thawed at the current moment among all the set frequencies in the entire preset database. The set frequency is then used as the optimal frequency corresponding to the items to be thawed at the current moment. Using the set frequency as the operating frequency can minimize the reflected power of the items to be thawed at the current moment, so that the thawing effect is optimal.

[0104] Step S400 , controlling the radio frequency thawing device 100 to operate at an operating frequency to thaw the food to be thawed in the radio frequency thawing device 100 .

[0105] After the operating frequency is matched from the preset database, the radio frequency thawing device 100 is controlled to operate at the operating frequency, so as to thaw the objects to be thawed at the current moment.

[0106] During the thawing process, as the temperature of the items to be thawed changes continuously, the impedance of the items to be thawed also changes continuously, causing the optimal frequency of the items to be thawed at different times to change. Therefore, after each preset thawing time, it is necessary to re-match the set frequency in the preset database as the operating frequency until the thawing is completed.

[0107] Step S510, obtaining the real-time temperature value of the item to be thawed.

[0108] After executing step S100 to step S400 once, the real-time temperature value of the object to be thawed in the current state is obtained, and whether the object to be thawed is completely thawed can be determined by the real-time temperature value.

[0109] It is easy to understand that the real-time temperature value refers to the temperature value of the item to be thawed in the current state, and the real-time temperature value can be detected by a temperature detector or a temperature detection module.

[0110] Step S520, determining whether the real-time temperature value is less than the set temperature value.

[0111] After obtaining the real-time temperature value, it is determined whether the real-time temperature value is less than the set temperature value. By determining the relationship between the real-time temperature value and the set temperature value, it can be determined whether the thawing of the items to be thawed is complete at the current moment.

[0112] The set temperature value may be set in advance, may be set at the factory, or may be set by the user according to his or her own needs.

[0113] Step S530: if the real-time temperature value is greater than or equal to the set temperature value, then exit the thawing mode.

[0114] If the real-time temperature value is greater than or equal to the set temperature value, it means that the real-time temperature value of the current item to be thawed is high and the thawing conditions have been met. At this time, the thawing mode can be exited and the thawing operation of the item to be thawed can be stopped.

[0115] If the real-time temperature value is less than the set temperature value, the next step of acquiring the reference data set from the preset database is triggered.

[0116] If the real-time temperature value is less than the set temperature value, it means that the real-time temperature value of the object to be thawed is still low and the thawing condition is not met, and steps S100 to S530 need to be repeated. The object to be thawed is thawed again.

[0117] In summary, the radio frequency thawing control method provided in the embodiment of the present application, in the embodiment of the present application, obtains a reference data group from a preset database, and can pre-screen a set frequency that is more suitable for the item to be thawed at the current moment from a plurality of set frequencies in the preset database. Firstly matching the reference data group from the preset database, and then matching the best frequency at the current moment from the reference data group can reduce the matching workload and improve the matching efficiency. Specifically, the following will describe in detail how to obtain the reference data group from the preset database.
