Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for adjusting a protection frequency of an ultrasonic device according to the present application. It should be noted that, if there are substantially the same results, the present embodiment is not limited to the flow sequence shown in fig. 1. The embodiment comprises the following steps:
step S11: at least one ultrasonic output frequency of the ultrasonic device during normal operation is obtained.
The ultrasonic device of the present application is, for example, a household appliance that uses an ultrasonic transducer, such as a cold extractor, that operates to generate ultrasonic waves and to transfer the generated wave energy to water or other food contained within the container.
Normal operation means that the ultrasonic output frequency is within the protection frequency range, and the protection mechanism is not triggered.
It will be appreciated that in a loaded situation the operating frequency of the ultrasonic transducer is relatively low and in an unloaded situation the operating frequency of the ultrasonic transducer is relatively high, and therefore a protective frequency range may be set, which includes a protective frequency lower limit value fa and a protective frequency upper limit value fb, and upon detecting that the operating frequency of the ultrasonic transducer exceeds the protective frequency range (i.e. that the operating frequency is below the frequency lower limit value fa or above the protective frequency upper limit value fb), the protective mechanism is triggered, the controllable means is turned off, or the voltage, power, etc. is reduced.
In an embodiment, when the ultrasonic device works normally, the ultrasonic output frequency is sampled at preset intervals to obtain at least one ultrasonic output frequency.
The preset interval time is, for example, 0.1 to 0.3 seconds, and can be set according to actual detection requirements.
Step S12: a degree of deviation between the at least one ultrasonic output frequency and the guard frequency mean is determined.
The protection frequency average value is an average value between a protection frequency upper limit value and a protection frequency lower limit value, the protection frequency upper limit value and the protection frequency lower limit value are used for determining a protection frequency range, and the protection frequency range is used for limiting the ultrasonic output frequency of the ultrasonic device.
Specifically, when the ultrasonic device is used for cooking and a load (such as water or other substances) is arranged in a corresponding container, ultrasonic energy is transmitted to the load, and the temperature rise of the ultrasonic transducer is small; under the condition of no load, the energy of the ultrasonic transducer is difficult to transfer out, so that the temperature of the transducer is higher, the device is easy to damage, and the service life of the device is reduced.
The deviation degree is used for measuring the deviation degree of the ultrasonic output frequency in the protection frequency range. In general, when the ultrasonic device works normally, the ultrasonic output frequency is stabilized at the protection frequency average value, or the protection frequency average value has small fluctuation, so that the deviation degree is zero or extremely small; when the ultrasonic device works abnormally, for example, when no water exists in the container, the output frequency of the ultrasonic device increases to exceed the upper limit of the protection frequency, the deviation degree can be considered to be large at the moment, and the detection module starts the protection measures after detecting that the ultrasonic frequency exceeds the frequency protection range so as to avoid damage to the device.
Researchers have long studied that during the use of the ultrasonic device, the ultrasonic output frequency may be unstable at the mean value of the protection frequency due to the influence of other factors, and even exceed the upper limit of the protection frequency, that is, the deviation degree may be increased, so that misjudgment occurs in the protection mechanism, and the ultrasonic device cannot work normally. For example, the aging of the device results in stress relief of the device, further resulting in an increase of the ultrasonic output frequency, and a degree of deviation from the mean value of the protection frequency becomes larger, even if the mean value of the protection frequency is higher than the upper limit of the protection frequency, which may cause misjudgment of the protection mechanism, so that the device is difficult to continuously work, and even cannot work normally.
In one embodiment, the deviation may be determined by a difference between the mean value of at least one ultrasonic output frequency and the mean value of the guard frequency, and if the difference is too large, the deviation may be high, and if the difference is small, the ultrasonic output frequency may be considered to be stable around the mean value of the guard frequency.
In other embodiments, the deviation may be further determined by sampling the ratio of the data greater than or less than the average guard frequency value, and if the ratio of the data greater than or less than the average guard frequency value is too high, the deviation may be determined to be high, and the guard frequency range may be adjusted; otherwise, the ratio of the ultrasonic wave output frequency is lower than or smaller than the protection frequency mean value, so that the fluctuation of the ultrasonic wave output frequency is smaller, the ultrasonic wave output frequency is stable around the protection frequency mean value, the misjudgment probability is low, and the protection frequency range is not required to be adjusted.
Step S13: and resetting the upper protection frequency limit value and/or the lower protection frequency limit value in response to the deviation exceeding the preset deviation threshold value.
The deviation degree exceeds the preset deviation threshold value, which indicates that the risk that the ultrasonic output frequency exceeds the protection frequency range is large, and the upper protection frequency limit value and/or the lower protection frequency limit value should be reset.
The principle of resetting the upper limit value of the protection frequency is as follows: the deviation degree is reduced, and the possibility that the ultrasonic output frequency exceeds the protection frequency is reduced.
For example, the difference between the average value of the ultrasonic output frequency and the average value of the guard frequency exceeds a preset deviation threshold, and when the average value of the ultrasonic output frequency is greater than the average value of the guard frequency, the upper limit value of the guard frequency can be selectively adjusted to be larger, and the lower limit value of the guard frequency can be selectively adjusted to be smaller or unchanged; when the difference between the average value of the ultrasonic output frequency and the average value of the protection frequency exceeds a preset deviation threshold, and when the average value of the ultrasonic output frequency is smaller than the average value of the protection frequency, the lower limit value of the protection frequency can be selectively adjusted to be smaller, and the upper limit value of the protection frequency can be selectively adjusted to be smaller or unchanged.
Specifically, the manner of resetting the guard frequency upper limit value and the guard frequency lower limit value is given in the following embodiments.
Compared with the prior art, the method can correct the upper limit value and/or the lower limit value of the protection frequency by judging the deviation degree between the ultrasonic output frequency and the mean value of the protection frequency when the ultrasonic device works normally, so as to prevent the ultrasonic output frequency from being increased or decreased silently due to the aging of a device or the change of capacitance and inductance parameters in a circuit, and finally, the ultrasonic device cannot be used normally under the condition of load.
The time from the start of the operation of the ultrasonic device to the normal shutdown of the completion of the operation is taken as a sampling period, and in the sampling period, sampling of the ultrasonic output frequency can be selected to be performed in any operation period, for example, data sampling can be performed in a preset time from the start of the operation, and sampling can also be performed at intervals of preset intervals in the period from the start of the operation of the ultrasonic device to the completion of the operation, so that sampling of the ultrasonic output frequency in the whole operation process of the ultrasonic device is obtained, and therefore, the judgment of the deviation degree of the sampling data is more accurate, and finally, the adjustment of the upper limit value and the lower limit value of the protection frequency is more accurate.
In one sampling period, if the protection mechanism is triggered, all sampling data of the sampling period are invalidated, deviation judgment is not carried out, and the upper limit value and the lower limit value of the protection frequency are not corrected, so that erroneous adjustment of the protection frequency range is avoided because the deviation judgment of the abnormal frequency data on the ultrasonic output frequency in the protection frequency range is inaccurate.
Referring to fig. 2, fig. 2 is a schematic flow chart diagram of another embodiment of a method for adjusting a protection frequency of an ultrasonic device according to the present application. It should be noted that, if there are substantially the same results, the embodiment is not limited to the flow sequence shown in fig. 2. The embodiment comprises the following steps:
step S21: at least one ultrasonic output frequency of the ultrasonic device during normal operation is obtained.
This step is the same as step S11 in the previous embodiment, and will not be described here again.
Step S22: a first average of the at least one ultrasonic output frequency is calculated.
Specifically, the at least one ultrasonic output frequency obtained in step S21 may be expressed as: f1, f2, …, fn, the first mean value of this step can be expressed as
Step S23: and determining the absolute value of the difference value between the first mean value and the guard frequency mean value, and taking the absolute value as the deviation degree.
Wherein, the guard frequency mean value can be expressed as:
the degree of deviation can then be expressed as
Step S24: and determining a magnitude relation between the first mean value and the second mean value in response to the deviation exceeding a preset deviation threshold.
If the degree of deviation
If the preset deviation threshold is exceeded, the deviation of the ultrasonic output frequency is considered to be excessive. It is required in step S25 that the first mean value is +.>
Mean value of protection frequency->
The magnitude relation of (2) determines the deflection of the ultrasonic output frequency.
If the degree of deviation
If the preset deviation threshold is not exceeded, the deviation of the ultrasonic output frequency is considered to be smaller, the possibility of erroneous judgment is smaller, the upper limit value and the lower limit value of the protection frequency which are set previously are reserved, and resetting is not performed.
In one embodiment, the preset deviation threshold may be 0, provided the degree of deviation exceeds 0 (i.e., provided
And->
Unequal), the deviation is considered to be too large and the guard frequency upper limit value and/or the guard frequency lower limit value need to be adjusted or reset.
In other embodiments, the preset deviation threshold may be other than 0, and a small deviation is allowed, where the specific value of the preset deviation threshold is not limited, and may be set by those skilled in the art as required.
Step S25: and if the first average value is larger than the protection frequency average value, determining to reset the protection frequency upper limit value, and if the first average value is smaller than the protection frequency average value, determining to reset the protection frequency lower limit value.
First mean value
Greater than the guard frequency mean->
The ultrasonic frequency output value is deviated towards the upper limit value of the protection frequency, so that the ultrasonic frequency output value is easily beyond the upper limit value of the protection frequency and is misjudged as no-load or other conditions needing to trigger a protection mechanism, and therefore the upper limit value of the protection frequency needs to be reset so as to reduce misjudgment. Wherein, only the upper limit value of the protection frequency can be selected to be reset, and the lower limit value of the protection frequency can be selected to be reset simultaneously.
Likewise, a first average value
Less than the guard frequency mean->
The ultrasonic frequency output value is deviated towards the direction of the protection frequency small limit value, and is easy to exceed the protection frequency lower limit value and is misjudged as the condition of triggering the protection mechanism, so that the protection frequency lower limit value needs to be reset to reduce misjudgment. Wherein, only the lower limit value of the protection frequency can be selected to be reset, and the upper limit value of the protection frequency can be selected to be reset at the same time.
According to the method, the first average value of the collected ultrasonic output frequency is directly utilized to be compared with the protection frequency average value, the protection frequency upper limit value and/or the protection frequency lower limit value are/is determined to be reset according to whether the difference value of the first average value and the protection frequency average value exceeds the preset deviation threshold value, the first average value can reflect the overall situation of all sampling data, the deviation degree judgment is acted, the accuracy of the deviation degree judgment is high, the calculated amount is small, and the requirement on the processing capacity is low.
Referring to fig. 3, fig. 3 is a schematic flow chart of another embodiment of a method for adjusting a protection frequency of an ultrasonic device according to the present application. It should be noted that, if there are substantially the same results, the embodiment is not limited to the flow sequence shown in fig. 3. The embodiment comprises the following steps:
step S31: at least one ultrasonic output frequency of the ultrasonic device during normal operation is obtained.
This step is the same as step S11 in the above embodiment, and will not be described here again.
Step S32: and determining the duty ratio of the at least one ultrasonic output frequency, which is larger than the protection frequency average value and the difference value between the at least one ultrasonic output frequency and the protection frequency average value exceeds a preset difference threshold value, or the duty ratio of the at least one ultrasonic output frequency, which is smaller than the protection frequency average value and the difference value between the at least one ultrasonic output frequency and the protection frequency average value exceeds the preset difference threshold value, wherein the duty ratio is the deviation degree.
Specifically, the duty ratio of the sampling data which is larger than the protection frequency mean value and the difference value between the sampling data and the protection frequency mean value exceeds a preset difference threshold value in the total sampling data is calculated, or the duty ratio of the sampling data which is smaller than the protection frequency mean value and the difference value between the sampling data and the protection frequency mean value exceeds the preset difference threshold value in the total sampling data is calculated, and the calculated duty ratio result is taken as the deviation degree.
Step S33: and if the ratio of the difference value between the at least one ultrasonic output frequency and the protection frequency average value, which is larger than the protection frequency average value, exceeds the preset difference threshold exceeds the first preset proportion, determining to reset the protection frequency upper limit value.
In the step, the first preset proportion is taken as a preset deviation threshold, if the duty ratio exceeds the first preset proportion, the deviation of the ultrasonic output frequency relative to the mean value of the protection frequency is considered to be overlarge, and the deviation is towards the upper limit value of the protection frequency, and the upper limit value of the protection frequency needs to be reset.
Optionally, the first preset proportion is between 40% and 80%, for example 40%, 60%, 80% etc.
Step S34: and if the ratio of the difference value smaller than the protection frequency average value and exceeding the preset difference threshold value in the at least one ultrasonic output frequency exceeds a second preset proportion, determining to reset the protection frequency lower limit value.
In the step, the first preset proportion is taken as a preset deviation threshold value, if the duty ratio exceeds the second preset proportion, the deviation of the ultrasonic output frequency relative to the mean value of the protection frequency is considered to be overlarge, and the deviation is towards the lower limit value of the protection frequency, and the lower limit value of the protection frequency needs to be reset.
Optionally, the first preset proportion is between 40% and 80%, for example 40%, 60%, 80% etc.
The second preset proportion and the first preset proportion can be the same or different.
Optionally, in the present embodiment, the ratio of the difference between the average value of the protection frequency and the average value of the protection frequency that is greater than the average value of the protection frequency and exceeds the preset difference threshold, and the ratio of the difference between the average value of the protection frequency and the average value of the protection frequency that is less than the average value of the protection frequency and exceeds the preset difference threshold may be calculated at the same time, if the results of the two steps satisfy the step S33 and the step S34 respectively, it may be determined that the deviation of the ultrasonic output frequency from the upper limit value of the protection frequency and the lower limit value of the protection frequency is relatively large, and it is determined that the upper limit value of the protection frequency and the lower limit value of the protection frequency need to be reset.
Alternatively, the preset variance threshold may be 0, or any value greater than 0.
In the embodiment, in the sampled data, the ratio of the difference value which is larger than the protection frequency mean value and exceeds the preset difference threshold is compared with the first preset ratio, the ratio of the difference value which is smaller than the protection frequency mean value and exceeds the preset difference threshold is compared with the second preset ratio, the distribution condition of the sampled data in the protection frequency range can be represented by the ratio result, and the judgment of the deviation degree is more accurate.
Referring to fig. 4, fig. 4 is a schematic block flow chart of an embodiment of resetting the guard frequency upper limit value in the present application. It should be noted that, if there are substantially the same results, the embodiment is not limited to the flow sequence shown in fig. 4. The embodiment comprises the following steps:
step S41: the first updated value is determined based on the first average value, the guard frequency lower limit value, and the guard frequency upper limit value.
Specifically, the sum of the average value of the difference between the guard frequency upper limit value and the guard frequency lower limit value and the first average value is taken as a first updated value.
The first updated value may be expressed as:
step S42: and using the first updated value as the upper limit value of the protection frequency to finish resetting the upper limit value of the protection frequency.
The difference between the second average value between the first updated value and the lower limit value of the protection frequency and the first average value is within a first preset error range. The first preset error range is, for example
Optionally, the guard frequency lower limit value can be adaptively adjusted to
The average value of the updated lower limit value of the protection frequency and the updated upper limit value of the protection frequency is in a first preset error range
Between them.
The present embodiment can reset the guard frequency upper limit value after determining to reset the guard frequency upper limit value, and optionally set the guard frequency lower limit value at the same time as the update value by using the sum of the average value of the difference between the guard frequency upper limit value and the guard frequency lower limit value and the first average value
The deviation of the ultrasonic output frequency in the protection frequency range is smaller, and the misjudgment of a protection mechanism is reduced.
Referring to fig. 5, fig. 5 is a schematic block flow chart of an embodiment of resetting the guard frequency lower limit value in the present application. It should be noted that, if there are substantially the same results, the embodiment is not limited to the flow sequence shown in fig. 5. The embodiment comprises the following steps:
step S51: the second updated value is determined based on the first average value, the guard frequency lower limit value, and the guard frequency upper limit value.
Specifically, the sum of the average value of the difference between the guard frequency lower limit value and the guard frequency upper limit value and the first average value is taken as a second updated value.
The second updated value may be expressed as:
step S52: and using the second updated value as a protection frequency lower limit value to finish resetting the protection frequency lower limit value.
The difference between the third average value between the second updated value and the upper limit value of the protection frequency and the first average value is within a second preset error range. The second preset error range is, for example
Optionally, the guard frequency upper limit value can be adaptively adjusted to
The average value of the updated lower limit value of the protection frequency and the updated upper limit value of the protection frequency is in a second preset error range
Between them.
The present embodiment can reset the guard frequency lower limit value after determining to reset the guard frequency lower limit value, and optionally set the guard frequency upper limit value at the same time as the update value by using the sum of the average value of the difference between the guard frequency lower limit value and the guard frequency upper limit value and the first average value
In order to make the deviation of the ultrasonic output frequency in the protection frequency range smaller and reduce the protectorAnd misjudgment is made.
In addition to the above, in another embodiment, the ultrasonic device may be subjected to ultrasonic output frequency detection under rated load and ultrasonic output frequency detection under no load, respectively, and the protection frequency upper limit value and the protection frequency lower limit value may be set according to the two measurement results.
Specifically, the ultrasonic output frequency under no load is F Empty space The ultrasonic output frequency under rated load is F Negative pole Setting the upper limit value of the protection frequency as F Negative pole -A, setting the upper limit value of the guard frequency to F Empty space +B, wherein A and B are settable frequency values, which may be equal or unequal, and specifically may be set according to the device conditions, and are not limited herein.
