[0003] In the related art, the main control module is communicatively connected with the display module and the variable frequency drive module; the display module and the variable frequency drive module are not directly communicatively connected; in actual application, due to external signal interference, cable disconnection and the like, the communication in the three modules will be interrupted, at this time, only the display module displays the corresponding information to remind the user to process. Although the display module reminds the user, the user's corresponding processing may have a large hysteresis, resulting in damage to the storage. SUMMARY

[0008] When the variable frequency drive module and the main control module have communication failure, the main control module is configured to control the load component according to the instruction temperature obtained from the display module; the variable frequency drive module is used to set the operating frequency and on-off time of the compressor according to the historical environmental temperature, and drive the compressor according to the operating frequency and on-off time of the compressor;
[0009] When the display module, the main control module and the variable frequency drive module all have communication failures, the main control module is configured to control the load assembly according to historical temperature; the variable frequency drive module is used to set the operating frequency and switching time of the compressor according to the historical environment temperature, and drive the compressor according to the operating frequency and switching time of the compressor.
[0010] By directly establishing a communication connection between the display module, the main control module and the variable frequency drive module, the situation that the display module and the variable frequency drive module cannot communicate due to communication failure of the main control module is prevented. Different processing measures are set for the refrigerator according to different communication failures, which can reduce the equipment failure or performance decline caused by communication problems to a certain extent, and reduce the damage to the storage caused by the user's failure to handle the fault in time.
[0011] Optionally, the main control module is electrically connected with an environment temperature sensor; the main control module is further configured to:
[0012] The environment temperature sensor is used to acquire the environment temperature in real time;
[0013] The environment temperature is transmitted to the variable frequency drive module.
[0014] The main control module acquires the environment temperature in real time and transmits it to the variable frequency drive module, and the variable frequency drive module can adjust the operating frequency of the compressor according to the environment temperature to accurately control the internal temperature. This accurate temperature control not only improves the energy efficiency ratio, but also helps to prolong the preservation time of the storage.
[0015] Optionally, when the environment temperature is less than or equal to 16℃, the operating frequency of the compressor is 1500rpm;
[0016] When the environment temperature is greater than 16℃ and less than 32℃, the operating frequency of the compressor is 2400rpm;
[0017] When the environment temperature is greater than or equal to 32℃, the operating frequency of the compressor is 3000rpm.
[0018] Adjusting the operating frequency of the compressor according to the environment temperature not only helps to maintain low energy consumption in low temperature environment, but also increases the operating frequency of the compressor as the environment temperature rises, which can also adapt to higher cooling demand. In addition, it can also effectively improve the energy efficiency ratio of the refrigerator, reduce the working load of the compressor, prolong the service life of the compressor, and reduce the risk of failure caused by long-time high-load operation.

[0023] The main control module controls the fan and the damper according to the historical temperature or the instruction temperature and the chamber temperature acquired in real time, which not only improves the refrigeration efficiency of the refrigerator, but also helps to prolong the service life of the equipment. Moreover, through accurate temperature control and intelligent fan and damper management, unnecessary energy consumption can be reduced while ensuring the refrigeration effect, and the user is more convenient in use, the complexity of operation is reduced, and the deterioration of storage caused by excessive temperature fluctuation is also reduced.

[0026] when the condensing temperature is lower than a preset condensing limit value, control the defrosting heater to be turned on;
[0027] when the opening time of the defrosting heater reaches a preset heater opening time, control the defrosting heater to be turned off.
[0028] The main control module can acquire the condensing temperature in real time through the condensing temperature sensor, which is used to intelligently control the opening and closing of the defrosting heater. Not only the defrosting efficiency of the refrigerator is improved, but also the service life of the equipment is prolonged. In addition, such intelligent control makes the user more convenient in use, reduces the complexity of operation, makes the defrosting control more stable, helps to keep the freshness of the storage, and improves the user experience.

[0031] when the historical ambient temperature is greater than or equal to 32℃, the operating frequency of the compressor is 3000rpm; the opening time of the compressor is 40 minutes; the closing time of the compressor is 20 minutes.
[0032] According to the historical ambient temperature, the operating frequency and the switching time of the compressor are adjusted, so that the refrigerator can maintain a high energy efficiency ratio under different temperature environments. In a low temperature environment, the operating frequency and the opening time of the compressor are reduced to reduce energy consumption; in a high temperature environment, the operating frequency and the opening time of the compressor are increased to enhance the refrigeration effect. In addition, such precise temperature control helps to prolong the preservation time of the stored goods and avoid the problem of deterioration of the stored goods due to excessive temperature fluctuations.

[0051] The embodiments will be described in detail below, and examples are shown in the drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following embodiments do not represent all embodiments consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application.
[0052] To solve the problem of storage damage in the case of communication abnormality, referring to Figure 1 The refrigerator with the communication abnormality processing function is provided, which comprises a display module, a main control module and a variable frequency driving module; the display module, the main control module and the variable frequency driving module are in communication connection with each other;
[0053] When the display module and the main control module have communication failure, the main control module is configured to control the load component according to historical temperature; wherein the historical temperature is set by the display module according to different temperature instructions of the refrigerator compartment; the variable frequency drive module is used to set the operating frequency of the compressor according to the ambient temperature obtained from the main control module, and drive the compressor according to the operating frequency of the compressor;
[0054] When the variable frequency drive module and the main control module have communication failure, the main control module is configured to control the load component according to the instruction temperature obtained from the display module; the variable frequency drive module is used to set the operating frequency and on-off time of the compressor according to the historical ambient temperature, and drive the compressor according to the operating frequency and on-off time of the compressor;
[0055] When the display module, the main control module and the variable frequency drive module all have communication failure, the main control module is configured to control the load component according to historical temperature; the variable frequency drive module is used to set the operating frequency and on-off time of the compressor according to the historical ambient temperature, and drive the compressor according to the operating frequency and on-off time of the compressor.
[0056] It should be understood that the main function of the compressor is to compress low-pressure and low-temperature refrigerant gas into high-pressure and high-temperature gas, thereby driving the refrigeration cycle system. The historical temperature can be the temperature set by the temperature instruction transmitted by the display module and the main control module before the communication failure. The historical ambient temperature can be the ambient temperature transmitted by the variable frequency drive module and the main control module before the communication failure.
[0057] By directly establishing a communication connection between the display module, the main control module and the variable frequency drive module, the situation that the display module and the variable frequency drive module cannot communicate due to communication failure of the main control module is prevented. Different processing measures are set for the refrigerator according to different communication failures, which can to some extent reduce the equipment failure or performance decline caused by communication problems, and reduce the damage to the storage caused by the user's failure to handle the failure in time.
[0058] In some embodiments, the main control module is electrically connected with an ambient temperature sensor; the main control module is further configured to:
[0059] The ambient temperature is obtained in real time by the ambient temperature sensor;
[0060] The ambient temperature is transmitted to the variable frequency drive module.
[0061] It should be understood that the ambient temperature sensor is arranged on the outer shell of the refrigerator for detecting the ambient temperature near the refrigerator.
[0062] The main control module acquires the ambient temperature in real time and transmits it to the variable frequency drive module. The variable frequency drive module can adjust the operating frequency of the compressor according to the ambient temperature to accurately control the internal temperature. This accurate temperature control not only improves the energy efficiency ratio, but also helps to prolong the preservation time of the stored goods.
[0063] In some embodiments, when the ambient temperature is less than or equal to 16℃, the operating frequency of the compressor is 1500rpm;
[0064] When the ambient temperature is greater than 16℃ and less than 32℃, the operating frequency of the compressor is 2400rpm;
[0065] When the ambient temperature is greater than or equal to 32℃, the operating frequency of the compressor is 3000rpm.
[0066] Adjusting the operating frequency of the compressor according to the ambient temperature not only helps to maintain low energy consumption in low temperature environments, but also increases the operating frequency of the compressor as the ambient temperature rises, which can also adapt to higher cooling demand. In addition, it can also effectively improve the energy efficiency ratio of the refrigerator, reduce the working load of the compressor, prolong the service life of the compressor, and reduce the risk of failure caused by long-term high-load operation.
[0067] In some embodiments, the load assembly includes a fan and a damper, and the refrigerator compartment is provided with a compartment temperature sensor; the fan, the damper and the compartment temperature sensor are electrically connected with the main control module; the main control module is configured to:
[0068] acquire the compartment temperature in real time through the compartment temperature sensor;
[0069] When the compartment temperature is higher than the historical temperature or the instruction temperature, the fan and the damper are controlled to be turned on;
[0070] When the compartment temperature is lower than or equal to the historical temperature or the instruction temperature, the fan and the damper are controlled to be turned off.
[0071] It should be understood that the fan is arranged in the air duct of the refrigerator, and the damper is arranged at the air outlet of the air duct near each refrigerator compartment, and each refrigerator compartment has at least one damper. The historical temperature or the instruction temperature is different for different compartments.
[0072] The master module controls the fan and the damper according to the historical temperature or the instruction temperature and the real-time acquired chamber temperature, not only improves the refrigeration efficiency of the refrigerator, but also helps to prolong the service life of the equipment. And through accurate temperature control and intelligent fan and damper management, unnecessary energy consumption can be reduced while ensuring the refrigeration effect, and the user is more convenient in use, the complexity of operation is reduced, and the deterioration of the storage caused by excessive temperature fluctuation is reduced.
[0073] In some embodiments, the load assembly further comprises a defrosting heater; a condensing temperature sensor is arranged on a condenser of the refrigerator, and the defrosting heater is located around the condenser; the master module is electrically connected with the defrosting heater and the condensing temperature sensor respectively; the master module is configured to:
[0074] acquire the condensing temperature in real time through the condensing temperature sensor;
[0075] when the condensing temperature is lower than a preset condensing limit value, control the defrosting heater to be turned on;
[0076] when the opening time of the defrosting heater reaches a preset heater opening time, control the defrosting heater to be turned off.
[0077] It should be understood that the main function of the condenser is to convert the refrigerant from a high-temperature and high-pressure gas state to a low-temperature and high-pressure liquid state, while dissipating heat to the external environment. The preset condensing limit value can be -15 degrees Celsius; the preset heater opening time can be set to 30 minutes.
[0078] The master module can acquire the condensing temperature in real time through the condensing temperature sensor, for intelligently controlling the opening and closing of the defrosting heater. Not only improves the defrosting efficiency of the refrigerator, but also helps to prolong the service life of the equipment. In addition, such intelligent control makes the user more convenient in use, reduces the complexity of operation, makes the defrosting control more stable, helps to keep the freshness of the storage, and improves the user's experience.

[0081] when the historical ambient temperature is greater than or equal to 32℃, the operating frequency of the compressor is 3000 rpm; the opening time of the compressor is 40 minutes; and the closing time of the compressor is 20 minutes.
[0082] The operating frequency and the opening time of the compressor are adjusted according to the historical ambient temperature, so that the refrigerator can maintain a high energy efficiency ratio in different temperature environments. In a low temperature environment, the operating frequency and the opening time of the compressor are reduced to reduce energy consumption; in a high temperature environment, the operating frequency and the opening time of the compressor are increased to enhance the refrigeration effect. In addition, such precise temperature control helps to prolong the preservation time of the stored goods and avoid the problem of deterioration of the stored goods due to excessive temperature fluctuations.
[0083] In some embodiments, the variable frequency drive module is further configured to: if no historical ambient temperature is received, the operating frequency of the compressor is 1500 rpm; the opening time of the compressor is 25 minutes; and the closing time of the compressor is 35 minutes.
[0084] In the case where no historical ambient temperature is received, the variable frequency drive module can automatically set the operating frequency of the compressor to 1500 rpm, the opening time to 25 minutes, and the closing time to 35 minutes. Such default settings ensure that the refrigerator can operate normally in any case, avoiding poor refrigeration effect or equipment failure due to lack of ambient temperature data.
[0085] In some embodiments, when the display module and the master control module have a communication failure, the display module is configured to display the communication failure information according to a first setting logic;
[0086] When the variable frequency drive module and the master control module have a communication failure, the display module is configured to display the communication failure information according to a second setting logic;
[0087] When the display module, the master control module and the variable frequency drive module all have a communication failure, the display module is configured to display the communication failure information according to the first setting logic and the second setting logic.
[0088] It should be understood that the first setting logic is used to accurately generate the communication failure information of the display module and the master control module, and the second setting logic is used to accurately generate the communication failure information of the variable frequency drive module and the master control module.
[0089] Different failure information is generated according to different types of failure, which enables the user to quickly and intuitively understand the location of the failure, check the cause of the failure and the way of repair on the display module, which helps to improve the repair efficiency and reduce the difficulty of the user in maintaining and maintaining the refrigerator.
