[0057] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0058] The following disclosure provides many different embodiments, or examples, for implementing different structures of the application. For the purpose of simplification, the components and arrangements of the specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the application. In addition, the application can refer to different examples and / or letters. Such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0059] Reference Figure 1 , Figure 1 A flowchart of a refrigerator control method provided by an embodiment of the application. The refrigerator control method provided by an embodiment of the application comprises the following steps:

[0060] S101: In the process of running the compressor in the refrigerator according to the preset control strategy, the first parameter information of the compressor is obtained.

[0061] In this embodiment, since the size of the harmonic generated by the refrigerator is related to the running condition of the compressor in the refrigerator, the running condition of the compressor can be monitored to obtain the first parameter information of the compressor in the process of running the compressor in the refrigerator according to the preset control strategy. The first parameter information can be the actual running power, and the size of the harmonic of the refrigerator is determined according to the actual running power of the compressor. When the harmonic of the refrigerator is small, the influence on the power system is small, and it can not be processed, and when the harmonic of the refrigerator is large (i.e. harmonic anomaly), the influence on the power system is large, so at this time the harmonic generated by the refrigerator needs to be suppressed. The preset control strategy can be understood as the control strategy without harmonic suppression, i.e. the control strategy for temperature regulation of the refrigerator compartment in the refrigerator without harmonic anomaly. It should be noted that the actual running power of the compressor can be obtained by obtaining the actual current and actual voltage of the compressor. Specifically, current sensors and voltage sensors can be arranged in the compressor to collect the actual current of the compressor by the current sensors and the actual voltage of the compressor by the voltage sensors.

[0062] S102: According to the first parameter information, the target running state of the refrigerator is determined.

[0063] In this embodiment, after obtaining the first parameter information, the first parameter information is logically judged to determine the target running state of the refrigerator. The target running state includes the existence of harmonic anomaly in the refrigerator and the non-existence of harmonic anomaly in the refrigerator. It should be noted that when the target running state is the existence of harmonic anomaly in the refrigerator, the following S103 step is executed; when the target running state is the non-existence of harmonic anomaly in the refrigerator, the compressor continues to run according to the preset control strategy, and returns to execute S101 step.

[0064] S103: In the case where the target operating state is that there is a harmonic abnormality in the refrigerator, second parameter information of a refrigerator compartment in the refrigerator is acquired.

[0065] In the present embodiment, in the case where it is determined according to the first parameter information of the compressor that there is a harmonic abnormality in the refrigerator, the harmonic current generated by the refrigerator needs to be suppressed to avoid affecting the operation of other equipment in the power system. The harmonic abnormality can be understood as a large harmonic in the refrigerator. Therefore, in the case where it is determined that there is a harmonic abnormality in the refrigerator, second parameter information of a refrigerator compartment in the refrigerator is acquired to control the refrigerator according to the acquired second parameter information of the refrigerator compartment, so as to suppress the harmonic in the refrigerator. The refrigerator compartment includes a refrigeration compartment and a freezing compartment, and the second parameter information includes a first actual temperature of the refrigeration compartment and a second actual temperature of the freezing compartment. It should be noted that a temperature sensor can be arranged in the refrigeration compartment to acquire the first actual temperature of the refrigeration compartment through the temperature sensor, and a temperature sensor can also be arranged in the freezing compartment to acquire the second actual temperature of the freezing compartment through the temperature sensor.

[0066] S104: The refrigerator is controlled according to the second parameter information.

[0067] In the present embodiment, after the first actual temperature of the refrigeration compartment and the second actual temperature of the freezing compartment are acquired, the gear of the compressor and / or the freezing compartment can be controlled according to the first actual temperature of the refrigeration compartment and the second actual temperature of the freezing compartment, so as to suppress the harmonic in the refrigerator while ensuring the preservation effect of the refrigeration compartment and the freezing effect of the freezing compartment.

[0068] The refrigerator control method provided by the present embodiment can suppress the harmonic current existing in the refrigerator according to the acquired second parameter information of the refrigerator compartment in the refrigerator in the case where the first parameter information of the compressor is monitored to determine that there is a harmonic abnormality in the refrigerator, without the need to improve the hardware structure of the refrigerator, thereby avoiding increasing the production cost of the refrigerator.

[0069] Reference Figure 2 , Figure 2 A flowchart of another refrigerator control method provided by the present embodiment is shown. The refrigerator control method provided by the present embodiment includes the following steps:

[0070] S201: In the case where the compressor in the refrigerator operates according to a preset control strategy, first parameter information of the compressor is acquired, and the first parameter information includes an actual operating power.

[0071] In the present embodiment, the step S201 is consistent with the step S101, and for details, reference can be made to the description of the step S101, which will not be repeated herein.

[0072] S202: Determine whether the actual running power is greater than or equal to the first preset running power.

[0073] S203: When the actual running power is less than the first preset running power, determine that the target running state of the refrigerator is that there is no harmonic abnormality in the refrigerator, and control the compressor to run according to the preset control strategy, and return to execute S201.

[0074] S204: When the actual running power is greater than or equal to the first preset running power, determine that the target running state of the refrigerator is that there is a harmonic abnormality in the refrigerator.

[0075] For the above S202 step-S204 step, since the harmonic current size in the refrigerator is related to the actual running power of the compressor, when the actual running power of the compressor is obtained, the harmonic current size in the refrigerator is determined according to the actual running power of the compressor. When the actual running power is greater than or equal to the first preset running power, it indicates that the harmonic is too high, and at this time, the refrigerator has a harmonic abnormality. If the harmonic in the refrigerator is not suppressed, it will affect the use of other equipment in the power system. When the actual running power is less than the first preset running power, it indicates that there is no harmonic abnormality in the refrigerator. The compressor can be controlled to run according to the preset control strategy under normal circumstances. During the process of running the compressor according to the preset control strategy, the actual running power of the compressor is obtained in real time, so that when the actual running power is greater than or equal to the first preset running power, S204 step is executed. It should be noted that the first preset running power can be set according to actual needs. The specific value of the first preset running power is not limited in this embodiment. For example, the first preset running power can be 100W.

[0076] S205: When the target running state is that there is a harmonic abnormality in the refrigerator, obtain the second parameter information of the refrigerator compartment in the refrigerator. The refrigerator compartment includes a refrigeration compartment and a freezing compartment. The second parameter information includes a first actual temperature of the refrigeration compartment and a second actual temperature of the freezing compartment.

[0077] S206: Determine the first comparison result between the first actual temperature and the first preset shutdown temperature corresponding to the refrigeration compartment.

[0078] S207: Determine the second comparison result between the second actual temperature and the second preset shutdown temperature corresponding to the freezing compartment.

[0079] S208: Control the refrigerator according to the first comparison result and the second comparison result.

[0080] In the case that the harmonic abnormality exists in the refrigerator, in order to realize the harmonic suppression in the refrigerator on the basis of guaranteeing the fresh-keeping effect of the refrigeration compartment and the freezing effect of the freezing compartment, the first actual temperature is compared with the first preset stop temperature corresponding to the refrigeration compartment and the second actual temperature is compared with the second preset stop temperature corresponding to the freezing compartment, so as to control the gear of the compressor and / or the freezing compartment according to the comparison results. It should be noted that the first preset stop temperature and the second preset stop temperature can be set according to actual needs, and the specific values of the first preset stop temperature and the second preset stop temperature are not limited in the embodiment. The first preset stop temperature is used to indicate the temperature of stopping the temperature control of the refrigeration compartment, and the second preset stop temperature is used to indicate the temperature of stopping the temperature control of the freezing compartment.

[0081] Before the step S206 is performed, the refrigerator control method provided in the embodiment further includes the following steps:

[0082] It is determined whether the first actual temperature is in a preset refrigeration temperature interval corresponding to the refrigeration compartment, and the first preset stop temperature is in the preset refrigeration temperature interval.

[0083] When the first actual temperature is in the preset refrigeration temperature interval, the step S206 is performed.

[0084] When the first actual temperature is not in the preset refrigeration temperature interval, the gear of the compressor is controlled to be downshifted.

[0085] During the downshifting of the compressor, if the actual running power is less than the first preset running power, the downshifting of the compressor is stopped, and the compressor is controlled to run at the gear.

[0086] When the first actual temperature is in the preset refrigeration temperature interval, the step S206 is performed.

[0087] In the embodiment, the preset refrigeration temperature interval is used to represent that the preservation effect of the refrigeration compartment can be achieved when the first actual temperature of the refrigeration compartment is in the preset refrigeration temperature interval. Therefore, before the step S206 is performed, it is determined whether the first actual temperature is in the preset refrigeration temperature interval. When the first actual temperature is in the preset refrigeration temperature interval, it is represented that the first actual temperature of the current refrigeration compartment can achieve the preservation effect, so the step S206 can be performed to further suppress the harmonic in the refrigerator. When the first actual temperature is not in the preset refrigeration temperature interval, it is represented that the first actual temperature of the current refrigeration compartment cannot achieve the effect, but the harmonic abnormality exists in the current refrigerator, so the compressor is controlled to downshift so that the actual operating power of the compressor is less than the first preset power, and the compressor is controlled according to the gear after the downshift of the compressor so that the first actual temperature of the refrigeration compartment is in the preset refrigeration compartment interval, and the step S206 is performed to further suppress the harmonic in the refrigerator. It should be noted that the preset refrigeration temperature interval can be set according to actual needs, and the specific values of the two endpoints of the preset refrigeration temperature interval are not limited in the embodiment. For example, the preset refrigeration temperature interval can be [0℃, 10℃].

[0088] In the embodiment, the control of the refrigerator according to the first comparison result and the second comparison result in the step S208 includes:

[0089] When the first comparison result is that the first actual temperature does not reach the first preset shutdown temperature, the compressor is controlled to downshift;

[0090] During the downshift of the compressor, if the actual operating power is less than the first preset operating power, the compressor is controlled to stop downshifting;

[0091] After the compressor stops downshifting, if the second comparison result is that the second actual temperature does not reach the second preset shutdown temperature, the refrigeration damper in the refrigerator is controlled to close;

[0092] When the closing time of the refrigeration damper reaches the first preset time, the compressor is controlled to upshift;

[0093] During the upshift of the compressor, if it is determined that the compressor meets the preset condition, the compressor is controlled to stop upshifting, and the preset condition includes that the gear of the compressor is the highest gear and the actual operating power is less than the first preset operating power, or the gear of the compressor is not the highest gear and the actual operating power reaches the second preset operating power, the second preset operating power being less than the first preset operating power;

[0094] After the compressor stops upshifting, the refrigeration damper in the refrigerator is controlled to open, and after the refrigeration damper is opened, the compressor is controlled to operate according to the preset control strategy.

[0095] In the above, when the first comparison result is that the first actual temperature does not reach the first preset shutdown temperature, since the first actual temperature of the refrigeration compartment is already in the preset refrigeration interval, the first actual temperature of the refrigeration compartment can play a preservation role when the harmonics are suppressed, so when the actual operating power of the compressor is greater than or equal to the first preset operating power, the frequency of the compressor can be directly reduced to make the compressor downshift, and then the actual operating power of the compressor is less than the first preset operating power. If the operating power of the compressor is less than the first preset operating power when the first comparison result is that the first actual temperature does not reach the first preset shutdown temperature, in order to further improve the preservation effect of the refrigeration compartment and the freezing effect of the freezing compartment, the compressor can not be controlled to downshift. After the compressor stops downshifting, if the second comparison result is that the second actual temperature does not reach the second preset shutdown temperature, it indicates that the second actual temperature of the freezing compartment cannot reach the freezing effect at present, and since the refrigeration compartment can already play a preservation role, the refrigeration damper in the refrigerator can be directly controlled to be closed to reduce the overall load of the refrigerator, so that the actual operating power of the compressor is also greatly reduced. In order to make the second actual temperature of the freezing compartment reach the second preset shutdown temperature as soon as possible, the closing time of the refrigeration damper is determined, and when the closing time reaches the first preset time, the compressor can be controlled to upshift to improve the temperature drawing speed and reduce the closing time of the refrigeration damper. If it is determined that the compressor meets the preset condition during the upshifting of the compressor, the compressor can be controlled to stop upshifting, the refrigeration damper can be controlled to be opened, and after the refrigeration damper is opened, the compressor can be controlled to operate according to the preset control strategy, and the step S201 is executed again. It should be noted that the first preset time can be set according to actual needs, and the specific value of the first preset time is not limited in the embodiment.

[0096] The preset condition is used to represent the condition for stopping the upshifting of the compressor. When the gear of the compressor is the highest gear and the actual operating power is less than the first preset operating power, the compressor can be controlled to stop upshifting; or when the gear of the compressor is not the highest gear and the actual operating power reaches the second preset operating power (the second preset operating power is less than the first preset operating power), the compressor can be controlled to stop upshifting. In this way, whether the compressor stops upshifting can be controlled by judging whether the compressor meets the preset condition. Specifically, the second preset operating power can be set according to actual needs, and the specific value of the second preset operating power is not limited in the embodiment.

[0097] It should be noted that after the compressor stops downshifting, if the second comparison result is that the second actual temperature reaches the second preset shutdown temperature, the compressor can be controlled to continue operating according to the preset control strategy, and the step S201 is executed again.

[0098] In the above, after the compressor stops the upshift, in order to further reduce the load of the whole refrigerator, the control of the closing of the refrigeration damper is continued, specifically as follows:

[0099] After the compressor stops the upshift, it is determined whether the closing time of the refrigeration damper reaches a second preset time, the second preset time being greater than the first preset time.

[0100] When the closing time of the refrigeration damper reaches the second preset time, the refrigeration damper in the refrigerator is controlled to be opened.

[0101] In the above, after the compressor stops the upshift, in order to further reduce the load of the whole refrigerator, the control of the closing of the refrigeration damper is continued, specifically as follows:

[0102] In this embodiment, the control of the refrigerator according to the first comparison result and the second comparison result in S206 includes:

[0103] When the first comparison result is that the first actual temperature reaches the first preset stop temperature, the refrigeration damper in the refrigerator is controlled to be closed.

[0104] After the refrigeration damper is closed, if the second comparison result is that the second actual temperature does not reach the second preset stop temperature, the compressor is controlled to be upshifted.

[0105] During the upshift of the compressor, if it is determined that the compressor meets a preset condition, the upshift of the compressor is stopped, the preset condition including that the gear of the compressor is the highest gear and the actual running power is less than the first preset running power, or the gear of the compressor is not the highest gear and the actual running power reaches a second preset running power, the second preset running power being less than the first preset running power.

[0106] After the compressor stops the upshift, the compressor is controlled to be run according to the preset control strategy.

[0107] In the above, when the first actual temperature reaches the first preset shutdown temperature, the refrigeration damper in the refrigerator can be directly controlled to be closed, and the closing of the refrigeration damper does not affect the preservation effect of the refrigeration compartment. When the second actual temperature of the freezing compartment does not reach the second preset shutdown temperature, the compressor can be controlled to be stepped up, so that the freezing compartment is quickly cooled to reach the second preset shutdown temperature. When the compressor meets the preset condition, the compressor can be controlled to stop stepping up, and after the compressor stops stepping up, the compressor is controlled to operate according to the preset control strategy. The preset condition is consistent with the above, which is not repeated here in this embodiment.

[0108] It should be noted that after the refrigeration damper is controlled to be closed, if the second comparison result is that the second actual temperature reaches the second preset shutdown temperature, the compressor can be controlled to continue operating according to the preset control strategy, and return to execute the step S201.

[0109] In this embodiment, after the step S208 is executed, the refrigerator control method provided by the embodiment further includes the following steps:

[0110] determining a continuous duration that the actual operating power is less than the first preset operating power;

[0111] when the continuous duration is greater than or equal to a third preset duration, controlling the compressor to operate according to the preset control strategy.

[0112] The third preset duration can be set according to actual needs, and the specific value of the third preset duration is not limited in this embodiment. For example, the third preset duration can be 60 minutes. After the refrigerator is controlled to suppress harmonics in the refrigerator, if the compressor is immediately controlled to operate according to the preset control strategy, it is most likely that the load of the refrigerator will also return to the original situation, so the continuous duration that the actual operating power is less than the first preset operating power is determined to ensure that the continuous duration is greater than or equal to the third preset duration, so that the refrigerator is cooled for a period of time, and the load of the refrigerator is reduced. In this way, the action of the compressor can be reduced, and the service life of the compressor is improved. It should be noted that when the continuous duration is less than the third preset duration, the step S208 needs to be executed to make the continuous duration greater than or equal to the third preset duration.

[0113] Specifically, in the step of controlling the compressor to run according to the preset control strategy after the compressor stops the step-up, the refrigeration damper in the refrigerator is controlled to be opened after the compressor stops the step-up, and a continuous time length during which the actual running power is less than the first preset running power is determined after the refrigeration damper in the refrigerator is opened. When the continuous time length is greater than or equal to the third preset time length, the compressor is controlled to run according to the preset control strategy; and when the continuous time length is less than the third preset time length, the step of determining whether the first actual temperature is in the preset refrigeration temperature interval of the refrigeration compartment is re-executed.

[0114] In addition, in the step of controlling the compressor to run according to the preset control strategy after the compressor stops the step-up, a continuous time length during which the actual running power is less than the first preset running power is determined after the compressor stops the step-up. When the continuous time length is greater than or equal to the third preset time length, the compressor is controlled to run according to the preset control strategy; and when the continuous time length is less than the third preset time length, the step of determining whether the first actual temperature is in the preset refrigeration temperature interval of the refrigeration compartment is re-executed.

[0115] The refrigerator control method provided in the embodiments of the present application can inhibit the harmonic current existing in the refrigerator according to the obtained second parameter information of the refrigerator compartment in the refrigerator when the first parameter information of the compressor is monitored to determine that the harmonic abnormality exists in the refrigerator, without improving the hardware structure of the refrigerator, thereby avoiding increasing the production cost of the refrigerator.

[0116] As an example, the control process of the refrigerator control method is specifically described below with reference to Figure 3 The control process of the refrigerator control method is specifically described below with reference to

[0117] controlling the compressor to run according to the preset control strategy;

[0118] obtaining the actual running power of the compressor;

[0119] determining whether the actual running power is greater than or equal to the first preset power;

[0120] when the actual running power is less than the first preset power, returning to execute the step of controlling the compressor to run according to the preset control strategy;

[0121] when the actual running power is greater than or equal to the first preset power, obtaining the first actual temperature of the refrigeration compartment and the second actual temperature of the freezing compartment;

[0122] determining whether the first actual temperature is in the preset refrigeration temperature interval;

[0123] when the first actual temperature is not in the preset refrigeration temperature interval, controlling the compressor to step down;

[0124] In the process of the compressor downshifting, if the actual running power is less than the first preset running power, the compressor is controlled to stop downshifting, and the compressor is controlled to run according to the gear so as to make the first actual temperature be in the preset refrigeration temperature interval;
