[0051] The refrigerator is one of the commonly used household appliances. The operation failure of the damper is one of the main reasons for abnormal refrigeration. Therefore, it is necessary to detect the operation failure of the damper. The refrigerator includes a damper assembly, and the damper assembly includes a driving mechanism, a transmission mechanism and a damper; the driving mechanism drives the transmission mechanism, and the transmission mechanism drives the damper to rotate. The driving mechanism is usually a motor, and the transmission mechanism is usually a gear transmission mechanism. Due to long-term operation and under complex working conditions, various faults may occur in the driving mechanism and the transmission mechanism, such as blockage, poor motor operation, damage, transmission mechanism jamming and other abnormalities, which affect the refrigeration effect and performance of the refrigerator. Therefore, it is necessary to perform fault detection on the driving mechanism and the transmission mechanism. In the prior art, whether the damper assembly is faulty is determined by detecting the position of the damper and the current of the driving mechanism. However, it is difficult to locate whether the damper assembly is faulty in the driving mechanism or the transmission mechanism. It is necessary to disassemble the machine to complete the accurate confirmation of the fault location, and the maintenance is difficult and inefficient.

[0052] Therefore, the embodiments of the present application provide a method, device, refrigerator, and computer storage medium for detecting a fault of a damper assembly. Specifically, the refrigerator provided in the embodiments of the present application includes a damper assembly, a vibration sensor group and / or a sound sensor group, and a controller. The controller is electrically connected to the damper assembly, and the vibration sensor group and / or the sound sensor group is electrically connected to the controller.

[0053] In an embodiment, a vibration sensor group is configured to collect a first vibration signal of the drive mechanism during the operation of the damper assembly and a second vibration signal of the transmission mechanism during the operation of the damper assembly; and / or a sound sensor group is configured to collect a first sound signal of the drive mechanism during the operation of the damper assembly and a second sound signal of the transmission mechanism during the operation of the damper assembly.

[0054] Specifically, in an embodiment, the vibration sensor group includes a first vibration sensor and a second vibration sensor, which are respectively configured to collect a first vibration signal of the drive mechanism during the operation of the damper assembly and a second vibration signal of the transmission mechanism during the operation of the damper assembly. The sound sensor group includes a first sound sensor and a second sound sensor, which are respectively configured to collect a first sound signal of the drive mechanism during the operation of the damper assembly and a second sound signal of the transmission mechanism during the operation of the damper assembly.

[0055] In an embodiment, the vibration sensor group may also be provided with a vibration sensor for collecting vibration signals of the driving mechanism when it is running, and then obtaining a first vibration signal of the damper assembly in operation and a second vibration signal of the transmission mechanism in operation of the damper assembly through filtering and other processing. The sound sensor group may also be provided with a sound sensor for collecting sound signals of the driving mechanism when it is running, and then obtaining a first sound signal of the damper assembly in operation and a second sound signal of the transmission mechanism in operation of the damper assembly through filtering and other processing.

[0056] In an embodiment, at least one of a vibration sensor group and a sound sensor group is provided in the refrigerator.

[0057] In an embodiment, the controller is configured to execute the steps in the damper assembly fault detection method proposed in the previous embodiment of the present application. Figure 1 As shown, the fault detection method of the damper assembly includes:

[0058] S110, controlling the driving mechanism to start, and obtaining a first vibration signal and / or a first sound signal of the driving mechanism;

[0059] S120, determining whether the driving mechanism fails according to the first vibration signal and / or the first sound signal; and / or

[0060] S210, controlling the driving mechanism to start, and obtaining a second vibration signal and / or a second sound signal of the transmission mechanism;

[0061] S220: Determine whether a fault occurs in the transmission mechanism according to the second vibration signal and / or the second sound signal.

[0062] In the technical solution of the embodiment of the present application, when the driving mechanism is started, the first vibration signal and / or the first sound signal of the driving mechanism is obtained to determine whether the driving mechanism is faulty. When the driving mechanism is started, the second vibration signal and / or the second sound signal of the transmission mechanism is obtained to determine whether the transmission mechanism is faulty; and further, in the technical solution of the embodiment of the present application, it is possible to determine whether the damper assembly is faulty in the driving mechanism or the transmission mechanism through the vibration or sound signal of the driving mechanism or the transmission mechanism, and the fault of the refrigerator damper can be accurately detected, thereby improving the maintenance efficiency of the refrigerator and improving the reliability and stability of the refrigerator.

[0063] like Figure 2 As shown, as an optional implementation of the above embodiment, the controlling the driving mechanism to start and obtaining the first vibration signal and / or the first sound signal of the driving mechanism includes:

[0064] S111, obtaining a first vibration signal and / or a first sound signal of the driving mechanism when the driving mechanism runs from a start-up moment to a first preset moment;

[0065] S112, obtaining a first vibration signal and / or a first sound signal when the driving mechanism runs from the second preset moment to the third preset moment; wherein the second preset moment is the same as the first preset moment, or the second preset moment is after the first preset moment;

[0066] The determining, according to the first vibration signal and / or the first sound signal, whether the driving mechanism fails comprises:

[0067] S121, judging whether a starting failure occurs in the driving mechanism according to a first vibration signal and / or a first sound signal running from a starting moment to a first preset moment;

[0068] S122, judging whether an operation failure occurs in the driving mechanism according to the first vibration signal and / or the first sound signal running from the second preset moment to the third preset moment.

[0069] In an embodiment, during the startup phase of the driving mechanism (from the startup moment to the first preset moment), the first vibration signal and / or the first sound signal of the driving mechanism is detected to determine whether the driving mechanism has a startup fault during the startup phase; during the operation phase of the driving mechanism (from the second preset moment to the third preset moment), that is, when the driving mechanism runs to the stable phase, the first vibration signal and / or the first sound signal of the driving mechanism is detected to determine whether the driving mechanism has an operation fault during the operation phase; so that during maintenance, the internal component failure of the driving mechanism can be accurately located.

[0070] In some embodiments, when the driving mechanism is operating normally, from the start-up time to the first preset time, the driving mechanism increases the speed from 0 to the preset speed; from the second preset time to the third preset time, the driving mechanism maintains the preset speed and drives the damper to the closed state or the open state. The first preset time, the second preset time and the third preset time are preset values ​​and are not specifically limited.

[0071] As an optional implementation of the above embodiment, Figure 3 As shown, controlling the driving mechanism to start and obtaining the second vibration signal and / or the second sound signal of the transmission mechanism includes:

[0072] S211, controlling the driving mechanism to start, controlling the damper in the damper assembly to switch from an open state to a closed state, or controlling the damper in the damper assembly to switch from the closed state to an open state;

[0073] S212, obtaining a second vibration signal and / or a second sound signal of the transmission mechanism when the damper switches from an open state to a closed state, or a second vibration signal and / or a second sound signal of the transmission mechanism when the damper switches from a closed state to an open state.

[0074] In an embodiment, when fault detection is performed on the transmission mechanism, the damper is switched from an open state to a closed state, or from a closed state to an open state, and during the switching process, a second vibration signal or a second sound signal is obtained, so as to determine whether a fault occurs in the transmission mechanism during the entire process of the damper switching.

[0075] It should be noted that, under normal circumstances, the drive mechanism needs to be started for T seconds for the damper to switch from an open state to a closed state or from a closed state to an open state. However, in the case of a fault, when the drive mechanism is started for T seconds, the damper may not be able to switch from an open state to a closed state or from a closed state to an open state due to a fault in the transmission mechanism. Therefore, in this special case, the drive mechanism is started for greater than or equal to T1 seconds, which can be understood as the damper switching from an open state to a closed state or from a closed state to an open state.

[0076] As an optional implementation of the above embodiment, Figure 4 As shown, the control of starting the driving mechanism, controlling the damper in the damper assembly to switch from an open state to a closed state, or controlling the damper in the damper assembly to switch from the closed state to an open state includes:

[0077] S2111, obtaining the position state of the damper,

[0078] S2112, if the position state is the open state, controlling the driving mechanism to start, controlling the damper in the damper assembly to switch from the open state to the closed state, and then controlling the damper in the damper assembly to switch from the closed state to the open state;

[0079] S2113, if the position state is the closed state, controlling the driving mechanism to start, controlling the damper in the damper assembly to switch from the closed state to the open state, and then controlling the damper in the damper assembly to switch from the open state to the closed state;

[0080] S2114, if the position state is between the open state or the closed state, control the driving mechanism to first drive the damper to switch to one of the open state or the closed state; then control the damper to switch from the first one of the open state or the closed state to the second one, and then control the damper to switch from the second one of the open state or the closed state to the first one.

[0081] That is, in the technical solution of the above embodiment, the damper needs to be switched from an open state to a closed state, and from a closed state to an open state, so as to determine whether the transmission mechanism has a fault during the whole process of switching the damper.

[0082] In step S2114, the damper may be in an intermediate state between the open state and the closed state. In this case, it is first driven to the open state or the closed state, and then switched back and forth between the open state and the closed state.

[0083] As an optional implementation of the above embodiment, if it is determined that the driving mechanism has not failed, the driving mechanism is controlled to start and the second vibration signal and / or the second sound signal of the transmission mechanism are obtained.

[0084] As an optional implementation of the above embodiment, Figure 5 As shown, judging whether the driving mechanism fails according to the first vibration signal and / or the first sound signal includes:

[0085] S123, determining a first vibration type and / or a first sound type according to the first vibration signal and / or the first sound signal;

[0086] S124, judging whether the driving mechanism fails according to the first vibration type and the first preset vibration type, and / or according to the first sound type and the first preset sound type; and / or

[0087] The determining, according to the second vibration signal and / or the second sound signal, whether the driving mechanism fails comprises:

[0088] S221, determining a second vibration type and / or a second sound type according to the second vibration signal and / or the second sound signal;

[0089] S222: Determine whether the driving mechanism fails according to the second vibration type and the second preset vibration type, and / or according to the second sound type and the second preset sound type.

[0090] In the technical solution of the embodiment of the present application, the first vibration preset type, the first sound preset type, the second vibration preset type and the second sound preset type are information set in the memory according to experimental data, which is the vibration type or sound type when the drive mechanism or the transmission mechanism is normal; the vibration type or sound type is determined by the vibration signal or the sound signal; the vibration type or sound type of the drive mechanism is then compared with the first vibration preset type or the first sound preset type, if they are consistent or the similarity is high, the drive mechanism is normal, if they are inconsistent or the similarity is low, the drive mechanism is faulty. Similarly, the vibration type or sound type of the transmission mechanism is then compared with the second vibration preset type or the second sound preset type, if they are consistent or the similarity is high, the transmission mechanism is normal, if they are inconsistent or the similarity is low, the transmission mechanism is faulty.

[0091] For example, under normal circumstances, the sound of the gear turning when the damper is opened is "buzzing", but when a fault occurs, it becomes "clicking"; if the detected sound of the gear turning is "buzzing", it is normal; if the detected sound of the gear turning is "clicking", which is inconsistent with the above, it is judged that the transmission mechanism is faulty.

[0092] For example, under normal circumstances, the gear rotation vibration when the damper is open is "low-frequency vibration", but it may become "high-frequency vibration" when a fault occurs; if the detected gear rotation vibration is low-frequency vibration, it is normal; if the detected gear vibration is high-frequency vibration, which is inconsistent with normal, it is judged that the transmission mechanism is faulty.

[0093] In the above embodiment, when a transmission mechanism or a driving mechanism fault is detected, the refrigerator issues a fault prompt, such as at least one of a prompt code, a prompt sound, and a prompt picture.

[0094] As an optional implementation of the above embodiment, the fault detection method responds to a refrigeration abnormality instruction or a user detection instruction. That is, in the technical solution of the embodiment of the present application, when a refrigeration abnormality instruction or a user detection instruction is received, the driving mechanism starts to run. When the driving mechanism is working, vibration and sound will be generated, and the transmission mechanism will also generate vibration and sound, and the damper rotates to achieve opening and closing; by the first vibration signal and / or the first sound signal of the driving mechanism or the second vibration signal and / or the second sound signal of the transmission mechanism, it is judged whether the damper assembly is faulty and which part is faulty. In this embodiment, the refrigerator can be provided with a self-check function, that is, when the refrigeration is abnormal, the fault detection method can be automatically executed, and it can be timely judged whether the abnormality is a damper assembly fault and which part of the damper assembly is faulty, thereby improving the detection and maintenance efficiency and saving labor costs.

[0095] In the above embodiments, the vibration signal or the sound signal can also be input into the fault prediction model respectively to determine whether it is normal or faulty; the fault prediction model includes a vibration fault prediction model of the driving mechanism, a sound fault prediction model of the driving mechanism, a vibration fault prediction model of the transmission mechanism, and a sound fault prediction model of the transmission mechanism. When the first vibration signal or the first sound signal of the driving mechanism is input into the vibration fault prediction model of the driving mechanism and the sound fault prediction model of the driving mechanism, it is determined whether the driving mechanism has a fault; when the second vibration signal or the second sound signal of the transmission mechanism is input into the vibration fault prediction model of the transmission mechanism and the sound fault prediction model of the transmission mechanism, it is determined whether the transmission mechanism has a fault. The vibration fault prediction model, the sound fault prediction model of the driving mechanism, the vibration fault prediction model of the transmission mechanism, and the sound fault prediction model of the transmission mechanism can be a deep learning model, a neural network model, etc.

[0096] In the technical solution of the above embodiment, if it is determined that the driving mechanism has not failed, the driving mechanism is controlled to restart, and the second vibration signal and / or the second sound signal of the transmission mechanism are obtained. Figure 1 As shown, step S100 is first executed to detect the fault of the driving mechanism, and when the driving mechanism has not failed, step S200 is then executed to detect the fault of the transmission mechanism. In the embodiment, if it is detected that the driving mechanism has a fault abnormality, the driving mechanism abnormality can be prompted to prompt the user to perform maintenance. During the maintenance process, the maintenance personnel will then detect whether the transmission mechanism is abnormal to avoid the driving mechanism continuing to operate when the driving mechanism is abnormal.

[0097] like Figure 6 As shown, the present application also proposes a fault detection device for a damper assembly, the fault detection device comprising:

[0098] A control module 10, configured to control the start-up of the driving mechanism;

[0107] The control module 10 is further configured to control the driving mechanism to restart if it is determined that the driving mechanism has not failed, and the acquisition module is configured to 20 acquire the second vibration signal and / or the second sound signal of the transmission mechanism.
