the operating frequency of the compressor is controlled in accordance with the amount of real-time acceleration exceeding an acceleration threshold.
Specifically, "acquiring real-time acceleration a of the compressor in preset X direction, Y direction and Z direction X 、a Y 、a Z The method comprises the following steps: the real-time acceleration a of the compressor in the preset X direction, Y direction and Z direction is respectively obtained through the vibration sensor X 、a Y 、a Z The method comprises the steps of carrying out a first treatment on the surface of the Of course, this is not a limitation.
Step "the real-time acceleration a to be acquired X 、a Y 、a Z Acceleration threshold A respectively corresponding to preset X direction, Y direction and Z direction X 、A Y 、A Z The comparison method specifically comprises the following steps:
the real-time acceleration a of the compressor in the X direction is obtained X With a preset acceleration threshold A in the X direction X Comparing the obtained real-time acceleration a of the compressor in the Y direction Y With a preset acceleration threshold A in the Y direction Y Comparing the obtained real-time acceleration a of the compressor in the Z direction Z With a preset acceleration threshold A in the Z direction Z Comparison.
Further, the acceleration threshold A X 、A Y 、A Z The value of (a) is not more than 2m/s 2 。
In one embodiment, the acceleration threshold A X 、A Y 、A Z Has a value of 2m/s 2 Of course, this is not a limitation.
It is understood that the number of real-time accelerations exceeding the acceleration threshold may be 0, or 1, or 2, or 3.
Specifically, "the number of real-time accelerations exceeding the acceleration threshold value is 0" means that the real-time acceleration a of the compressor in the X direction X Acceleration threshold A in the X direction smaller than a preset value X Real-time acceleration a of compressor in Y direction Y Acceleration threshold A in Y direction smaller than preset Y Real-time acceleration a of compressor in Z direction Z Acceleration threshold A smaller than preset Z direction X 。

"the number of real-time accelerations exceeding the acceleration threshold value is 2" means that the real-time acceleration a of the compressor in the X direction X Acceleration threshold A greater than a preset X direction X Real-time acceleration a of compressor in Y direction Y Acceleration threshold A greater than preset Y direction Y Real-time acceleration a of compressor in Z direction Z Acceleration threshold A smaller than preset Z direction Z The method comprises the steps of carrying out a first treatment on the surface of the Alternatively, the real-time acceleration a of the compressor in the X direction X Acceleration threshold A greater than a preset X direction X Real-time acceleration a of compressor in Y direction Y Acceleration threshold A in Y direction smaller than preset Y Real-time acceleration a of compressor in Z direction Z Acceleration threshold A greater than preset Z direction Z The method comprises the steps of carrying out a first treatment on the surface of the Or real-time acceleration a of the compressor in the X direction X Acceleration threshold A in the X direction smaller than a preset value X Real-time acceleration a of compressor in Y direction Y Acceleration threshold A greater than preset Y direction Y Real-time acceleration a of compressor in Z direction Z Acceleration threshold A greater than preset Z direction Z 。

It will be appreciated that when the number of real-time accelerations exceeding the acceleration threshold is 0, this indicates that the vibration of the compressor is small, and further, that the greater the number of real-time accelerations exceeding the acceleration threshold, the greater the vibration of the compressor, the more noise is generated.
Further, when the "control the operating frequency of the compressor" is to decrease the operating frequency of the compressor, the greater the number of real-time accelerations exceeding the acceleration threshold value, the lower the operating frequency of the compressor.
That is, the more the number of real-time accelerations exceeding the acceleration threshold value is, the larger the frequency-reducing amplitude of the compressor is, so that the vibration of the compressor can be reduced, the noise is reduced, and the use experience of a user is improved.
Further, when the number of real-time accelerations exceeding the acceleration threshold value is 0, "the operation frequency of the compressor is controlled according to the number of real-time accelerations exceeding the acceleration threshold value" is: and controlling the compressor to keep the original operating frequency.
When the number of real-time accelerations exceeding the acceleration threshold is 1, in one embodiment, the step of controlling the operation frequency of the compressor according to the number of real-time accelerations exceeding the acceleration threshold is: controlling the compressor to reduce the first preset frequency f 1 The latter operating frequency operates.
That is, the operation frequency of the compressor is reduced to reduce the vibration amplitude of the compressor, thereby achieving the effect of reducing noise and improving the use experience of users.
In one embodiment, the first preset frequency f 1 Is 5% of the original operating frequency. Of course, this is not a limitation.
The above and hereinafter the original operating frequency refers to the operating frequency of the compressor before the step of controlling the operating frequency of the compressor according to the amount of real-time acceleration exceeding the acceleration threshold value.
Further, after "the number of real-time accelerations exceeding the acceleration threshold is 1", the control method of the refrigerator further includes the steps of:
acquiring the real-time temperature in the refrigerating compartment, and obtaining a real-time temperature difference delta t between the real-time temperature and a preset shutdown temperature;
judging whether the real-time temperature difference delta T is larger than a preset temperature difference delta T, if yes, controlling the fan to increase the rotating speed n of the first fan 1 The rotation speed after the operation is carried out; if not, controlling the fan to maintain the original rotation speed to run.
It can be understood that when the real-time temperature difference Δt is greater than the preset temperature difference Δt, it indicates that the required cooling capacity in the refrigeration compartment is relatively large, and at this time, the operating frequency of the compressor is reduced due to the noise problem of the compressor, the cooling capacity of the refrigeration system is reduced, resulting in relatively large temperature fluctuation in the refrigeration compartment, and affecting the fresh-keeping effect. Therefore, the rotation speed of the fan is increased while the operation frequency of the compressor is reduced, so that the heat exchange efficiency is improved, the temperature fluctuation in the refrigeration compartment is reduced, and the refrigeration compartment reaches the shutdown temperature as soon as possible.
Specifically, the preset temperature difference Δt=5 ℃, the n being 1 Is 5% of the original rotation speed. Of course, this is not a limitation.
The above and hereinafter the original rotational speed refers to the operation rotational speed of the blower before the step of controlling the operation frequency of the compressor according to the amount of real-time acceleration exceeding the acceleration threshold value.
In another embodiment, when the number of real-time accelerations exceeding the acceleration threshold is 1, after "the number of real-time accelerations exceeding the acceleration threshold is 1", the control method of the refrigerator further includes the following steps:
acquiring the real-time temperature in the refrigerating compartment, and obtaining a real-time temperature difference delta t between the real-time temperature and a preset shutdown temperature;
judging whether the real-time temperature difference delta T is larger than a preset temperature difference delta T, if yes, controlling the operation frequency of the compressor to control the compressor to raise a second preset frequency f 2 The operation frequency is operated; if not, controlling the operation frequency of the compressor to control the compressor to reduce the first preset frequency f 1 The latter operating frequency operates.
It can be understood that in this embodiment, only when the real-time temperature difference Δt is smaller than the preset temperature difference Δt, that is, the cooling capacity required in the refrigeration compartment is low, the operation frequency of the compressor is reduced to reduce the vibration amplitude of the compressor, thereby achieving the effect of reducing noise and improving the use experience of the user.
When the real-time temperature difference Deltat is larger than the preset temperature difference Deltat, the fact that the required cooling capacity in the refrigerating chamber is larger is shown, and at the moment, if the operating frequency of the compressor is reduced, the cooling capacity of the refrigerating system is reduced, so that the temperature fluctuation in the refrigerating chamber is larger, therefore, in the embodiment, the operating frequency of the compressor is staggered from the resonance frequency by increasing the operating frequency of the compressor, and vibration noise caused by frequency resonance is reduced, so that the purpose of reducing noise is achieved; meanwhile, the running frequency of the compressor is increased, the cooling capacity of the refrigerating system can be increased, and the refrigerating compartment can be rapidly refrigerated.
Specifically, the second preset frequency f 2 The frequency is set to be 5% of the original operating frequency, and the influence of vibration and resonance of the compressor caused by frequency up-conversion on noise is considered.
When the number of real-time accelerations exceeding the acceleration threshold is 2, in one embodiment, the step of controlling the operation frequency of the compressor according to the number of real-time accelerations exceeding the acceleration threshold is: controlling the compressor to reduce a third preset frequency f 3 The latter operating frequency operates.
That is, the operation frequency of the compressor is reduced to reduce the vibration amplitude of the compressor, thereby achieving the effect of reducing noise and improving the use experience of users.
In particular, according to the above-mentioned publication "The operation frequency of the compressor is controlled to be lower as the number of real-time accelerations exceeding the acceleration threshold value is larger when the operation frequency of the compressor is reduced. Third preset frequency f 3 > first preset frequency f 1 Thereby, the compressor reduces the third preset frequency f 3 The latter operating frequency is less than the compressor to reduce the first preset frequency f 1 The latter operating frequency. The better noise reduction effect can be achieved.
In one embodiment, the third preset frequency f 3 Is 10% of the original operating frequency. Of course, this is not a limitation.
Further, after "the number of real-time accelerations exceeding the acceleration threshold is 2", the control method of the refrigerator further includes the steps of:
acquiring the real-time temperature in the refrigerating compartment, and obtaining a real-time temperature difference delta t between the real-time temperature and a preset shutdown temperature;
judging whether the real-time temperature difference delta T is larger than a preset temperature difference delta T, if yes, controlling the fan to increase the rotating speed n of the second fan 2 The rotation speed after the operation is carried out; if not, controlling the fan to maintain the original rotation speed to run.
It can be understood that when the real-time temperature difference Δt is greater than the preset temperature difference Δt, it indicates that the required cooling capacity in the refrigeration compartment is relatively large, and at this time, the operating frequency of the compressor is reduced due to the noise problem of the compressor, the cooling capacity of the refrigeration system is reduced, resulting in relatively large temperature fluctuation in the refrigeration compartment, and affecting the fresh-keeping effect. Therefore, the rotation speed of the fan is increased while the operation frequency of the compressor is reduced, so that the heat exchange efficiency is improved, the temperature fluctuation in the refrigeration compartment is reduced, and the refrigeration compartment reaches the shutdown temperature as soon as possible.
Specifically, the preset temperature difference Δt=5℃.
In one embodiment, the n 2 As will be appreciated, the compressor operating frequency is 2 when the number of real-time accelerations exceeding the acceleration threshold is compared to 1 when the number of real-time accelerations exceeding the acceleration threshold is 10% of the original rotational speedThe rate, namely, the cooling capacity of the refrigerating system is lower, so that compared with the case that the number of the real-time acceleration exceeding the acceleration threshold value is 1, the rotating speed of the fan is further increased, the heat exchange efficiency can be further improved, the temperature fluctuation in the refrigerating compartment is reduced, and a better fresh-keeping effect is achieved, so that the refrigerating compartment reaches the shutdown temperature as soon as possible.
In another embodiment, when the number of real-time accelerations exceeding the acceleration threshold is 2, after "the number of real-time accelerations exceeding the acceleration threshold is 2", the control method of the refrigerator further includes the following steps:
acquiring the real-time temperature in the refrigerating compartment, and obtaining a real-time temperature difference delta t between the real-time temperature and a preset shutdown temperature;
judging whether the real-time temperature difference delta T is larger than a preset temperature difference delta T, if yes, controlling the operation frequency of the compressor to control the compressor to raise a fourth preset frequency f 4 The operation frequency is operated; if not, controlling the operation frequency of the compressor to control the compressor to reduce the third preset frequency f 3 The latter operating frequency operates.
It can be understood that in this embodiment, only when the real-time temperature difference Δt is smaller than the preset temperature difference Δt, that is, the cooling capacity required in the refrigeration compartment is low, the operation frequency of the compressor is reduced to reduce the vibration amplitude of the compressor, thereby achieving the effect of reducing noise and improving the use experience of the user.
When the real-time temperature difference Deltat is larger than the preset temperature difference Deltat, the fact that the required cooling capacity in the refrigerating chamber is larger is shown, and at the moment, if the operating frequency of the compressor is reduced, the cooling capacity of the refrigerating system is reduced, so that the temperature fluctuation in the refrigerating chamber is larger, therefore, in the embodiment, the operating frequency of the compressor is staggered from the resonance frequency by increasing the operating frequency of the compressor, and vibration noise caused by frequency resonance is reduced, so that the purpose of reducing noise is achieved; meanwhile, the running frequency of the compressor is increased, the cooling capacity of the refrigerating system can be increased, and the refrigerating compartment can be rapidly refrigerated.
Specifically, the fourth preset frequency f 4 Setting upThe frequency is 5% of the original operating frequency, and the influence of vibration and resonance of the compressor caused by frequency up-conversion on noise is considered, but the frequency is not limited to this.
At a real time acceleration exceeding the acceleration threshold of 3, an excessive compressor vibration amplitude is indicated, and at this time, the compressor vibration amplitude must be reduced only by reducing the operating frequency of the compressor, thereby reducing noise.
Specifically, when the number of real-time accelerations exceeding the acceleration threshold value is 3, the step of controlling the operating frequency of the compressor according to the number of real-time accelerations exceeding the acceleration threshold value is: controlling the compressor to reduce a fifth preset frequency f 5 The latter operating frequency operates.
That is, the operation frequency of the compressor is reduced to reduce the vibration amplitude of the compressor, thereby achieving the effect of reducing noise and improving the use experience of users.
Specifically, according to the above, when the "controlling the operation frequency of the compressor" is to reduce the operation frequency of the compressor, the greater the number of real-time accelerations exceeding the acceleration threshold value, the lower the operation frequency of the compressor. Fifth preset frequency f 5 > third preset frequency f 3 > first preset frequency f 1 Thereby, the compressor reduces the fifth preset frequency f 5 The latter operating frequency is less than the compressor to reduce the third preset frequency f 3 The operation frequency can achieve better noise reduction effect.
In one embodiment, the fifth preset frequency f 5 15% of the original operating frequency. Of course, this is not a limitation.
Further, after "the number of real-time accelerations exceeding the acceleration threshold is 3", the control method of the refrigerator further includes the following steps:
acquiring the real-time temperature in the refrigerating compartment, and obtaining a real-time temperature difference delta t between the real-time temperature and a preset shutdown temperature;
judging whether the real-time temperature difference delta T is larger than a preset temperature difference delta T, if so, controlling a fan to improve a third temperature difference delta TFan speed n 3 The rotation speed after the operation is carried out; if not, controlling the fan to maintain the original rotation speed to run.
It can be understood that when the real-time temperature difference Δt is greater than the preset temperature difference Δt, it indicates that the required cooling capacity in the refrigeration compartment is relatively large, and at this time, the operating frequency of the compressor is reduced due to the noise problem of the compressor, the cooling capacity of the refrigeration system is reduced, resulting in relatively large temperature fluctuation in the refrigeration compartment, and affecting the fresh-keeping effect. Therefore, the rotation speed of the fan is increased while the operation frequency of the compressor is reduced, so that the heat exchange efficiency is improved, the temperature fluctuation in the refrigeration compartment is reduced, and the refrigeration compartment reaches the shutdown temperature as soon as possible.
Specifically, the preset temperature difference Δt=5℃.
In one embodiment, the n 3 As can be appreciated, when the number of real-time accelerations exceeding the acceleration threshold is 3, the operating frequency of the compressor is lower than that of the compressor when the number of real-time accelerations exceeding the acceleration threshold is 2 or 1, that is, the cooling capacity of the refrigerating system is lower, so that the heat exchange efficiency can be further improved, the temperature fluctuation in the refrigerating compartment is reduced, and a better fresh-keeping effect is achieved, so that the refrigerating compartment reaches the shutdown temperature as soon as possible, compared with that when the number of real-time accelerations exceeding the acceleration threshold is 1 or 2.
Referring to fig. 1, a control method of a refrigerator according to a first embodiment of the present invention, wherein "the frequency of controlling the compressor according to the amount of real-time acceleration exceeding the acceleration threshold" in the control method of the refrigerator specifically includes:
when the number of real-time accelerations exceeding the acceleration threshold value is 0, controlling the compressor to keep the original running frequency;
controlling the compressor to reduce the first preset frequency f when the number of the real-time accelerations exceeding the acceleration threshold value is 1 1 The operation frequency is operated;
controlling the compressor to reduce the third preset frequency f when the number of real-time accelerations exceeding the acceleration threshold value is 2 3 The operation frequency is operated;
controlling the compressor to reduce the fifth preset frequency f when the number of real-time accelerations exceeding the acceleration threshold value is 3 5 The operation frequency is operated;
wherein f 1 ＜f 3 ＜f 5 。
In this embodiment, all through the control compressor down conversion, reduce the rotational speed of compressor to, can reduce the vibration of compressor, noise reduction promotes user's use and experiences.
Meanwhile, the more the quantity of real-time acceleration exceeding the acceleration threshold value is, the larger the frequency-reducing amplitude of the compressor is, so that the vibration of the compressor can be reduced according to specific conditions, the noise is reduced, and the use experience of a user is improved.
Specifically, the first preset frequency f 1 5% of the original operating frequency; the third preset frequency f 3 10% of the original operating frequency; the fifth preset frequency f 5 15% of the original operating frequency, although this is not a limitation.
Referring to fig. 2, a control method of a refrigerator according to a second embodiment of the present invention is shown, and the second embodiment is different from the first embodiment only in that:
after "the number of real-time accelerations exceeding the acceleration threshold value" is obtained, the control method of the refrigerator further includes the steps of:
acquiring the real-time temperature in the refrigerating compartment, and obtaining a real-time temperature difference delta t between the real-time temperature and a preset shutdown temperature;
judging whether the real-time temperature difference delta T is larger than a preset temperature difference delta T, if so, controlling the fan to operate at a rotating speed after the rotating speed of the preset fan is increased; if not, controlling the fan to maintain the original rotation speed to run.
It can be understood that when the real-time temperature difference Δt is greater than the preset temperature difference Δt, it indicates that the required cooling capacity in the refrigeration compartment is relatively large, and at this time, the operating frequency of the compressor is reduced due to the noise problem of the compressor, the cooling capacity of the refrigeration system is reduced, resulting in relatively large temperature fluctuation in the refrigeration compartment, and affecting the fresh-keeping effect. Therefore, the rotation speed of the fan is increased while the operation frequency of the compressor is reduced, so that the heat exchange efficiency is improved, the temperature fluctuation in the refrigeration compartment is reduced, and the refrigeration compartment reaches the shutdown temperature as soon as possible.
Specifically, the preset temperature difference Δt=5℃.
In a specific embodiment, the "controlling the fan to operate at a rotational speed after increasing the rotational speed of the preset fan" specifically includes the following cases:
when the number of the real-time accelerations exceeding the acceleration threshold value is 1, controlling the fan to increase the first fan rotating speed n 1 The rotation speed after the operation is carried out;
when the number of the real-time accelerations exceeding the acceleration threshold value is 2, controlling the fan to increase the rotating speed n of the second fan 2 The rotation speed after the operation is carried out;
when the number of the real-time accelerations exceeding the acceleration threshold value is 3, controlling the fan to increase the rotating speed n of the third fan 3 The rotation speed after the operation is carried out;
wherein the first fan rotating speed n 1 < second fan speed n 2 < third fan speed n 3 。
It can be understood that the more the number of real-time acceleration exceeding the acceleration threshold value, the lower the running frequency of the corresponding compressor, namely the lower the cooling capacity of the refrigerating system, so that the rotating speed of the fan needs to be further increased, the heat exchange efficiency can be further improved, the temperature fluctuation in the refrigerating compartment is reduced, and the better fresh-keeping effect is achieved, so that the refrigerating compartment reaches the shutdown temperature as soon as possible.
In one embodiment, the first fan speed n 1 5% of the original rotation speed, the second fan rotation speed n 2 10% of the original rotation speed, the third fan rotation speed n 3 15% of the original rotation speed. Of course, this is not a limitation.
The second embodiment of the present invention is identical to the first embodiment except for the above differences, and the details are not repeated here.
Referring to fig. 3, a control method of a refrigerator according to a third embodiment of the present invention is shown, and the third embodiment is different from the second embodiment in that: when the number of the real-time accelerations exceeding the acceleration threshold is 1 or 2, if the real-time temperature difference Deltat is larger than the preset temperature difference Deltat, controlling the compressor to operate at the operating frequency after the preset frequency is increased, and at the moment, not increasing the rotating speed of the fan.
When the real-time temperature difference Deltat is larger than the preset temperature difference Deltat, the fact that the cooling capacity required in the refrigerating chamber is larger is indicated, at the moment, if the operating frequency of the compressor is reduced, the cooling capacity of the refrigerating system is reduced, so that the temperature fluctuation in the refrigerating chamber is larger, and the fresh-keeping effect is influenced, therefore, in the third embodiment, when the number of real-time acceleration exceeding the acceleration threshold is 1 or 2, namely the vibration amplitude of the compressor is not particularly large, the mode of increasing the operating frequency of the compressor is adopted, the operating frequency of the compressor is staggered with the resonance frequency, and vibration noise caused by frequency resonance is reduced, so that the purpose of reducing the noise is achieved; meanwhile, the cooling capacity of the refrigerating system can be increased, and the refrigerating compartment can be rapidly refrigerated.
Specifically, when the number of real-time accelerations exceeding the acceleration threshold is 1, if the real-time temperature difference Δt is greater than the preset temperature difference Δt, the compressor is controlled to raise the second preset frequency f 2 The operation frequency is operated; when the number of the real-time accelerations exceeding the acceleration threshold value is 2, if the real-time temperature difference Deltat is larger than the preset temperature difference Deltat, controlling the compressor to increase the fourth preset frequency f 4 The latter operating frequency operates.
In one embodiment, the second preset frequency f 2 And a fourth preset frequency f 4 The frequency is 5% of the original operating frequency, and the influence of vibration and resonance of the compressor caused by frequency up-conversion on noise is considered, but the frequency is not limited to this.
It will be appreciated that at a real time acceleration level of 3 exceeding the acceleration threshold, an excessive compressor vibration amplitude is indicated, and at this point, the compressor vibration amplitude must be reduced, and only by reducing the operating frequency of the compressor, to reduce noise. Therefore, when the number of real-time accelerations exceeding the acceleration threshold value is 3, the corresponding control method in the second embodiment can be adopted.
