Description

Technical Field

[0001] The present disclosure relates to the technical field of smart refrigerators, and in particular to a refrigerator fault detection method, device, electronic device and storage medium. Background Art

[0002] During the operation of the refrigerator, when there is a gap between the refrigerator door or the door is opened frequently to take out food in a short period of time, due to the pressure difference between the inside and outside of the refrigerator, a large amount of outside air will enter the refrigerator compartment or freezer compartment inside the refrigerator. The water vapor in the outside air will condense when it gets cold inside the refrigerator, causing frost on the surface of the refrigerator fan blades, which in turn causes the fan speed to decrease. In severe cases, the fan may stop, affecting the refrigeration efficiency of the refrigerator.

[0003] In the prior art, when judging whether the fan of a refrigerator is faulty, a feedback signal when the fan is running is usually obtained, and the feedback signal is compared with a preset value to judge whether the fan is faulty. However, when the above method is used to judge whether the fan of a refrigerator is faulty, if the air in the refrigerator cold room fluctuates violently, such as when the refrigerator door is opened and closed, the fan speed will be unstable, so that the obtained feedback signal is lower than the preset value, resulting in an erroneous judgment that the fan is faulty, and it is impossible to accurately judge whether the fan is faulty.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0046] In a first aspect, at least one embodiment of the present disclosure provides a refrigerator fault detection method, the specific steps are as follows: Figure 1 As shown, the method includes:

[0047] Step S101, obtaining a cooling capacity difference between a first cooling capacity delivered by the refrigerator and a second cooling capacity provided by the compressor within a preset time.

[0048] In the disclosed embodiment, when the refrigerator is running, the first cold amount transmitted by the refrigerator and the second cold amount provided by the compressor within a preset time are respectively obtained, wherein the first cold amount is the cold amount required to maintain the temperature corresponding to the current gear of the refrigerator, and the second cold amount is the cold amount required to maintain the refrigerator at the current gear. The cold amount difference is obtained by using the obtained first cold amount and the second cold amount. Specifically, for example, when the refrigerator is running in the second gear and maintains the temperature corresponding to the second gear, the first cold amount transmitted by the refrigerator, that is, the cold amount required for the refrigerator to maintain the current temperature, is obtained, and at the same time, the second cold amount required to be provided by the compressor, that is, the cold amount required to be provided by the refrigerator to maintain the current temperature, is obtained, and the cold amount difference is obtained by using the first cold amount and the second cold amount.

[0049] Step S102, detect whether the cooling capacity difference meets the preset conditions, and maintain the fan speed when the preset conditions are met; if the preset conditions are not met, control the fan speed to change from the first speed to the second speed at a set speed increase, wherein the second speed is greater than the first speed.

[0050] In the disclosed embodiment, after executing step S101, it is detected whether the cooling capacity difference obtained in step S101 meets the preset conditions, wherein, when the preset conditions are met, it can be determined that the operation state of the fan is normal, and when the preset conditions are not met, it is determined that the operation of the fan is abnormal, and it is necessary to control the first speed of the fan to set the increase in speed to change to the second speed, so as to change the abnormal operation of the fan by controlling the change in the fan speed, wherein the set increase in speed in this embodiment is used to rapidly change the fan speed from a first speed with a lower speed to a second speed with a higher speed, and the numerical value of the set increase in speed can be set by those skilled in the art according to actual conditions, so as to achieve the rapid change of the fan speed from a first speed with a lower speed to a second speed with a higher speed. The preset condition in this embodiment can be a preset differential cooling capacity range.

[0051] Step S103, repeatedly executing the steps of obtaining the cooling capacity difference and detecting whether the cooling capacity difference satisfies a preset condition, and determining that the fan of the refrigerator is faulty when the detection of whether the cooling capacity difference satisfies the preset condition is executed for a preset number of times, and the number of times the cooling capacity difference does not satisfy the preset condition reaches a first threshold, wherein the preset number of times is greater than the first threshold.

[0052] In the disclosed embodiment, after executing step S102, step S101 and step S102 are repeatedly executed. After executing step S102 for a preset number of times, the number of times the cooling difference does not satisfy the preset condition is counted. When the number of times the cooling difference does not satisfy the preset condition reaches a first threshold, it is determined that the fan of the refrigerator has failed. When the number of times the cooling difference does not satisfy the preset condition does not reach the first threshold, it is determined that the fan of the refrigerator has not failed.

[0053] In one example, the first threshold value can be set to be greater than half of the preset number of times. For example, when the preset number of times is 10, the first threshold value can be set to 6. Those skilled in the art can also set the preset number of times and the first threshold value according to actual needs. At the same time, in this embodiment, when counting the number of times the cooling capacity difference does not meet the preset condition, the number of times the cooling capacity difference does not meet the preset condition can be counted after step S102 is repeated for a preset number of times, or the number of times the cooling capacity difference does not meet the preset condition can be counted once each time step S102 is repeated, wherein, when the actual number of times step S102 is repeated does not reach the preset number of times, and the number of times the cooling capacity difference does not meet the preset condition reaches the first threshold, then the repetition of steps S101 and S102 can be stopped.

[0054] The refrigerator fault detection method provided by the embodiment of the present disclosure first obtains the difference between the first cold amount delivered by the refrigerator and the second cold amount provided by the compressor within a preset time, and determines whether the cold amount difference meets the preset condition, thereby controlling the operation of the fan using the judgment result, and further repeats the acquisition of the cold amount difference and the detection of whether the cold amount difference meets the preset condition. When the detection of whether the cold amount difference meets the preset condition is performed for a preset number of times, and the number of times the cold amount difference does not meet the preset condition reaches a first threshold, it is determined that the refrigerator fan has failed. The present disclosure can effectively avoid the influence of airflow disturbance on the operation of the fan by using the first cold amount and the second cold amount, and can effectively avoid the influence of accidental factors on the judgment of the fan fault by repeatedly obtaining the cold amount difference and judging whether the cold amount difference meets the preset condition for multiple times, so that it can accurately judge whether the fan has failed, thereby improving the accuracy of the judgment of the fan fault.

[0055] In some embodiments, when executing step S102 to determine whether the cooling difference meets the preset condition, it includes obtaining the cooling difference for a first number of consecutive times, and when the number of times the cooling difference exceeds the preset difference range is less than a second threshold, it is determined that the cooling difference meets the preset condition, otherwise it is determined that the cooling difference does not meet the preset condition.

[0056] In the disclosed embodiment, when executing step S102, the cooling capacity difference is obtained for a first number of times in succession, that is, the cooling capacity difference is obtained for a plurality of times in succession, and each cooling capacity difference is compared with a preset difference range, and the number of times the cooling capacity difference exceeds the preset difference range is counted. When the number of times the cooling capacity difference exceeds the preset difference range is less than a second threshold value, it is determined that the cooling capacity difference satisfies the preset condition. When the number of times the cooling capacity difference exceeds the preset difference range is greater than or equal to the second threshold value, it is determined that the cooling capacity difference does not satisfy the preset condition. Among them, the first number of times in the present embodiment is preferably set to 3 times, and those skilled in the art can also set the first number of times according to actual needs. At the same time, when judging whether the cooling capacity difference satisfies the preset condition, the present embodiment can improve the accuracy of judging whether the cooling capacity difference satisfies the preset condition by comparing the cooling capacity difference obtained for a plurality of times in succession with the preset difference range, thereby effectively avoiding the influence of reading data errors.

[0057] In some embodiments, when executing step S101, the following steps may be included:

[0058] Step S201, determining the amount of cold delivered by the refrigerating chamber according to the temperature difference of the refrigerating chamber within a preset time.

[0059] In the disclosed embodiment, the refrigerator includes a refrigerating chamber and a freezing chamber, and when determining the first amount of cold, the temperature difference of the refrigerating chamber within a preset time is first obtained, and the amount of cold transferred by the refrigerating chamber is determined using the obtained temperature difference.

[0060] Step S202, determining the amount of cold transferred by the freezing chamber according to the temperature difference of the freezing chamber within a preset time.

[0061] In the embodiment of the present disclosure, while obtaining the temperature difference of the refrigerating chamber, the temperature difference of the freezing chamber within a preset time is also obtained, and the amount of cold transferred by the freezing chamber is determined using the obtained temperature difference.

[0062] Step S203, determining the first cooling capacity according to the cooling capacity transferred by the refrigerating chamber and the cooling capacity transferred by the freezing chamber.

[0063] In the disclosed embodiment, after executing steps S201 and S202, the first cooling amount is determined by using the determined cooling amount transferred by the refrigerating chamber and the cooling amount transferred by the freezing chamber. Specifically, in the present embodiment, the first cooling amount is determined based on the sum of the cooling amount transferred by the refrigerating chamber and the cooling amount transferred by the freezing chamber. In the present embodiment, the first cooling amount can be accurately obtained based on the sum of the cooling amount of the refrigerating chamber and the cooling amount of the freezing chamber, so that the first cooling amount can be used to accurately determine whether the refrigerator fan fails, thereby improving the accuracy of determining refrigerator fan failure.

[0064] In some embodiments, when determining the second rotation speed, the following steps are also included:

[0065] Step S301: when the cooling capacity difference is greater than or equal to a third threshold, determining that the second speed is the maximum speed of the fan.

[0066] In the disclosed embodiment, when the fan is controlled to change from the first speed to the second speed at a set speed increase, the obtained cooling capacity difference is compared with the third threshold value, wherein the third threshold value is used to characterize the severity of the abnormal operation of the fan, and can be determined by a person skilled in the art according to the actual situation of the refrigerator. When it is determined that the cooling capacity difference is greater than or equal to the third threshold value, it is determined that the abnormal operation of the fan is more serious, and therefore, the second speed is determined as the maximum speed of the fan, so as to control the fan to change from the first speed to the maximum speed of the fan at a set speed increase.

[0067] Step S302: when the cooling capacity difference is less than a third threshold, determining the second speed as the current speed of the fan.

[0068] In the disclosed embodiment, when the fan is controlled to change from the first speed to the second speed at a set speed increase, the obtained cooling capacity difference is compared with the third threshold value, and when it is judged that the cooling capacity difference is less than the third threshold value, it is judged that the abnormal operation of the fan is relatively light, and therefore, the second speed is determined as the current speed of the fan, wherein the current speed is the speed corresponding to the current gear of the refrigerator, so as to control the fan to change from the first speed to the current speed of the fan at a set speed increase. By comparing the cooling capacity difference with the third threshold value, this embodiment can accurately grasp the abnormal operation of the fan, and then accurately control the change of the fan speed, and further improve the accuracy of fan fault judgment.

[0069] In some embodiments, when it is determined that the fan of the refrigerator has failed, it also includes controlling the refrigerator to issue a fault alarm, or sending fault information to a mobile terminal associated with the refrigerator, or controlling the refrigerator to issue a fault alarm and send fault information to a mobile terminal associated with the refrigerator. Specifically, the fault alarm in this embodiment can be issued by a buzzer installed on the refrigerator, and the fault information in this embodiment can be sent to a mobile terminal bound to the refrigerator to remind the user that the refrigerator has failed. In this embodiment, by controlling the refrigerator to issue a fault alarm, or sending fault information to a mobile terminal associated with the refrigerator, the user can be informed of the operation of the refrigerator in a timely manner, and the refrigerator can be repaired in a timely manner, thereby avoiding the occurrence of food spoilage in the refrigerator due to a failure in the operation of the refrigerator fan, improving the user experience, and further extending the service life of the refrigerator.

[0070] Further, the present disclosure provides another refrigerator fault detection method in an embodiment, please refer to Figure 2 As shown, before executing the refrigerator fault detection method provided by the present embodiment, the compressor speed, fan speed and damper angle of the refrigerator are first set, that is, the compressor speed, fan speed and damper angle of the refrigerator remain unchanged when the refrigerator is running, and further start to obtain the cooling difference between the first cooling amount delivered by the refrigerator and the second cooling amount provided by the compressor within Δt (that is, the preset time). After the cooling difference is obtained, the number of times the cooling difference is obtained is increased by 1, that is, N=N+1, where N represents the number of times the cooling difference is obtained, and then it is determined whether the cooling difference exceeds the preset difference range. When the cooling difference exceeds the preset difference range, the number of times the cooling difference exceeds the preset difference range is increased by 1, that is, M=M+1, where M represents the number of times the cooling difference exceeds the preset difference range.

[0071] It is further determined whether the number of times the cooling difference is obtained reaches a first number, that is, whether N is equal to N0, wherein N0 represents a first number, for example, it can be set to 3. When it is determined that the number of times the cooling difference is obtained does not reach the first number, the step of obtaining the cooling difference between the first cooling delivered by the refrigerator and the second cooling provided by the compressor within Δt (i.e., a preset time) is continued. When it is determined that the obtained cooling difference reaches the first number, it is further determined whether the number of times the cooling difference exceeds the preset difference range is greater than a second threshold, that is, whether M is greater than or equal to M0, wherein M0 represents a second threshold, for example, it can be set to 2. When the number of times the cooling difference exceeds the preset difference range is greater than or equal to the second threshold, the fan is controlled to change from the first speed to the second speed at a set speed increase. When the number of times the cooling difference exceeds the preset difference range is less than the second threshold, the fan speed is maintained.

[0072] Further, when the fan is controlled to change from the first speed to the second speed at a set speed increase, the number of times the cooling capacity difference does not meet the preset condition is increased by 1, that is, Q=Q+1, where Q represents the number of times the cooling capacity difference does not meet the preset condition. At the same time, after the fan is controlled to change from the first speed to the second speed at a set speed increase, or the fan speed is maintained, the number of steps of detecting whether the number of times the cooling capacity difference exceeds the preset difference range is greater than the second threshold value is increased by 1, that is, A=A+1, where A represents the number of steps of detecting whether the number of times the cooling capacity difference exceeds the preset difference range is greater than the second threshold value.

[0073] Further, it is determined whether the number of times the cooling difference is detected to exceed the preset difference range is greater than the second threshold, and whether the number of times reaches the preset number, that is, whether A is less than or equal to A0, for example, it can be set to 10, wherein A0 represents the preset number of times, and at the same time, it is determined whether the number of times the cooling difference does not meet the preset condition reaches the first threshold, that is, whether Q is greater than Q0, wherein Q0 represents the first threshold, for example, it can be set to 6, before executing the acquisition of the cooling difference between the first cooling amount delivered by the refrigerator and the second cooling amount provided by the compressor within Δt (i.e., the preset time) and before the number of times the cooling difference is determined to exceed the preset difference range has not reached the first number, and the number of times the cooling difference does not meet the preset condition reaches the first threshold, that is, A≤A0, and Q>Q0, it is determined that the fan has failed, and the refrigerator is controlled to issue a fault alarm, and / or send a fault message to the mobile terminal bound to the refrigerator.

[0074] According to a second aspect of the embodiment of the present disclosure, a refrigerator fault detection device is provided. Figure 3 As shown, the device comprises:

[0076] The control module 302 is used to detect whether the cooling capacity difference meets a preset condition, and maintain the fan speed if the preset condition is met; if the preset condition is not met, control the fan speed to change from a first speed to a second speed at a set speed increase, wherein the second speed is greater than the first speed;

[0077] The determination module 303 is used to repeatedly execute the acquisition of the cooling difference and the detection of whether the cooling difference meets the preset condition, and determine that the fan of the refrigerator fails when the detection of whether the cooling difference meets the preset condition is performed for a preset number of times and the number of times the cooling difference does not meet the preset condition reaches a first threshold, wherein the preset number of times is greater than the first threshold.

[0078] In some embodiments, the control module 302 is specifically used to obtain the cooling difference for a first number of consecutive times, and when the number of times the cooling difference exceeds a preset difference range is less than a second threshold, it is determined that the cooling difference satisfies the preset condition; otherwise, it is determined that the cooling difference does not satisfy the preset condition.
