[0048] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying 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 exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0049] Figure 1 is a flow chart of a method for controlling a compressor according to an exemplary embodiment. Figure 1 As shown, the following steps are included.
[0050] In step S11 , in response to receiving a triggered shutdown instruction, a scenario triggering the shutdown instruction is determined.
[0051] The scenarios for triggering the shutdown command may include a shutdown triggered by the compressor in a non-fault scenario and a shutdown triggered by a compressor fault.
[0052] In one possible implementation, if the shutdown command is triggered by the user when the compressor is operating normally, then it can be determined that the scenario is a shutdown triggered by the compressor in a non-fault scenario. For example, if the shutdown command is generated when the user issues a shutdown command to an electrical device (such as an air conditioner, etc.) that uses the compressor, then it is determined that the scenario is a shutdown triggered by the compressor in a non-fault scenario.
[0053] In another possible implementation, if the shutdown command is triggered by a compressor failure, it can be determined that the scenario is a shutdown triggered by a compressor failure. For example, if the shutdown command is triggered when the compressor has overcurrent protection, overvoltage protection, and F0 protection failures, then the scenario is determined to be a shutdown triggered by a compressor failure.
[0054] In step S12, a target shutdown mode corresponding to the scenario is determined from a plurality of preset shutdown modes.
[0055] For example, different shutdown methods can be pre-configured for different scenarios that trigger a shutdown command; for example, for a shutdown triggered by a compressor in a non-fault scenario, the configured shutdown methods may include: controlling the compressor to reduce the frequency and then stop working at a lower operating frequency to reduce the vibration caused by the compressor stopping working; for another example, for a shutdown triggered by a compressor fault, the compressor can be immediately controlled to stop or reduce the frequency at a faster speed to shorten the working time of the compressor in a fault condition, thereby ensuring the safety of the compressor.
[0056] In step S13, the compressor is controlled to shut down according to the target shutdown mode.
[0057] By adopting the above scheme, the shutdown process of the compressor can be controlled by determining the target shutdown method for the compressor. Since the target shutdown method matches the actual scenario that triggers the shutdown instruction of the compressor, the shutdown process of the compressor can be more in line with the actual scenario of the compressor, thereby ensuring the safety of the compressor in all scenarios.
[0058] In some embodiments, when the scenario includes a shutdown triggered by a compressor fault, the above step S12 may include: determining the fault type of the compressor fault, and determining a target shutdown method corresponding to the scenario from a plurality of preset shutdown methods according to the fault type.
[0059] In the event that the compressor shuts down due to a fault, the fault type of the compressor may include a first fault type and a second fault type, the fault priority of the first fault type is higher than the fault priority of the second fault type, and the fault type of the compressor is the first fault type or the second fault type, which can be determined based on the fault priority that triggers the shutdown command.
[0060] By way of example, the fault type may include a first fault type and a second fault type, wherein the fault priority of the first fault type is higher than the fault priority of the second fault type, wherein a higher fault priority indicates a more serious fault and a higher harm caused (such as worse user experience or safety). For example, faults of the first fault type may include: overcurrent protection, overvoltage protection or F0 protection in electrical equipment, etc., and faults of the second fault type may include sensor open circuit fault or sensor short circuit fault in electrical equipment, etc.
[0061] For example, a fault whose priority is greater than or equal to a priority threshold can be regarded as a first fault type, and a fault whose priority is less than the priority threshold can be regarded as a second fault type; wherein the priority threshold can be determined according to the severity of the fault, for example, whether it will reduce the service life of the compressor or damage components in the compressor.
[0062] In this way, the fault priority of the compressor can be used to determine whether the fault of the compressor is the first fault type or the second fault type, which is conducive to taking corresponding shutdown methods for the compressor under different fault types to ensure the safety of the compressor.
[0063] In the case where the fault types include the first fault type, the compressor can be controlled to shut down; here, since the first fault type has a higher fault priority, the harm of the first fault type to the compressor may be higher than the harm of the compressor's shutdown vibration to the compressor, and shutting down the compressor under the first fault type as soon as possible is beneficial to ensuring the safety of the compressor; for example, when the compressor has overcurrent protection or overvoltage protection, shutting down the compressor as soon as possible is beneficial to avoiding damage to the compressor due to larger current or higher voltage.
[0064] Therefore, when the fault type includes the first fault type, it indicates that the current fault is relatively serious, and the compressor can be directly controlled to shut down, thereby avoiding serious safety problems for the compressor.
[0065] In a case where the fault type includes the second fault type, a first current operating frequency of the compressor may be determined, and the compressor may be controlled to stop according to the first current operating frequency.
[0066] Compared with the situation where the compressor is triggered to shut down under non-fault scenarios, the second fault type is more harmful to the compressor. The long-term operation of the compressor under the second fault type is not conducive to the safety of the compressor. At the same time, compared with the situation where the compressor is triggered to shut down under the first fault type scenario, the compressor has a more sufficient shutdown time when the second fault type occurs. By shortening the shutdown time of the compressor under the second fault type, the vibration amplitude of the compressor when it shuts down can be reduced while ensuring the safety of the compressor.
[0067] In a possible implementation, when the first current operating frequency is greater than or equal to a preset operating frequency, the operating frequency of the compressor can be controlled to decrease; when the first current operating frequency of the compressor is reduced to a preset frequency, the compressor is controlled to stop.
[0068] The fault type includes the second fault type, indicating that the current fault type is less severe than the first fault type. Therefore, the operating power of the compressor can be controlled to decrease to a preset operating frequency according to a preset frequency reduction speed. The preset operating frequency can be the operating frequency corresponding to the minimum vibration amplitude when the compressor is running within a preset frequency range. Controlling the compressor to stop working at the preset operating frequency can reduce the vibration caused by the compressor stopping working. The preset frequency range can be determined according to the maximum frequency of the compressor. For example, the maximum frequency of the compressor is used as the upper limit of the preset frequency range.
[0069] In this way, when the first current operating frequency is greater than or equal to the preset operating frequency, by reducing the frequency of the compressor to the preset frequency and then shutting down the compressor, the vibration amplitude when the compressor is shut down at the preset frequency will be smaller than the vibration amplitude when it is shut down directly before the frequency is reduced, thereby ensuring the safety of the compressor and reducing the vibration when the compressor is shut down.
[0070] In another possible implementation, when the first current operating frequency is less than the preset operating frequency, the compressor can be controlled to shut down. For example, when the compressor of the air conditioner outdoor unit or the compressor of the refrigerator receives a shutdown instruction triggered by the second fault type, since the shutdown vibration of the compressor is small when it shuts down at the preset operating frequency, if the operating frequency of the compressor is less than the preset operating frequency, the shutdown vibration of the compressor when it shuts down immediately will be smaller, and the compressor can be controlled to shut down immediately.
[0071] In this way, the vibration of the compressor when it stops in the event of the second fault type can be effectively reduced, and there is no need to reduce the operating frequency of the compressor to 0 before shutting down, which shortens the required time for the compressor to shut down in the event of the second fault type, and enables the compressor to shut down quickly in the second fault type, thereby ensuring the safety of the compressor.
[0072] In another embodiment, when the compressor has the second fault type, if the compressor receives a shutdown protection instruction, the compressor can be controlled to shut down immediately. In this way, by receiving the shutdown protection instruction and controlling the compressor to shut down immediately, the compressor can be quickly shut down under the second fault type, thereby ensuring the safety of the compressor under the second fault type.
[0073] In other embodiments, when the scenario includes a shutdown of the compressor triggered in a non-fault scenario, the above step S12 may include: determining a second current operating frequency of the compressor, and controlling the compressor to shut down according to the second current operating frequency.
[0074] Compared with the case where the compressor is triggered to shut down under a fault scenario, the compressor has a sufficient shutdown time when it is triggered to shut down under a non-fault scenario. The compressor can be controlled to shut down according to the second current operating frequency to minimize the vibration amplitude of the compressor when it is shut down, thereby improving the user experience of the compressor.
[0075] In one embodiment, based on the second current operating frequency, controlling the compressor to stop may include: when the second current operating frequency is greater than or equal to a preset operating frequency, controlling the operating frequency of the compressor to reduce the frequency; when the second current operating frequency of the compressor is reduced to a preset frequency, determining the mechanical angle of the compressor; when the mechanical angle of the compressor is within a target angle range, controlling the compressor to stop.
[0076] Among them, the mechanical angle of the compressor refers to the angle of the compressor rotor relative to the initial position. The speed fluctuation of the compressor at different mechanical angles is different, and the vibration amplitude of the compressor when it stops at different mechanical angles is also different.
[0077] In a non-fault scenario, the compressor continues to work after frequency reduction and does not affect the safety of the compressor. The vibration amplitude of the compressor when it stops working at the preset operating frequency is smaller. When the second current operating frequency is greater than or equal to the preset operating frequency, the vibration of the compressor shutdown process can be effectively reduced by reducing the frequency of the compressor to the preset operating frequency.
[0078] When the operating frequency of the compressor decreases to the preset operating frequency, the mechanical angle of the compressor is determined, and the compressor is controlled to stop when the mechanical angle of the compressor is within the target angle range. The speed fluctuation of the compressor is smaller within the target angle range. Stopping the compressor under smaller speed fluctuation can further reduce the vibration when the compressor is stopped.
[0079] In one embodiment, the target angle range can be determined in the following manner: when the compressor is running at a preset operating frequency, the compressor is controlled to stop at multiple mechanical angles to be tested; the vibration amplitude of the compressor stopping at each mechanical angle to be tested is obtained; the minimum vibration amplitude is determined from the obtained vibration amplitudes; and the target angle range is determined according to the mechanical angle to be tested corresponding to the minimum vibration amplitude. For example, the target angle range may include all mechanical angles corresponding to the minimum vibration amplitude.
[0080] In this way, by determining the mechanical angle corresponding to the minimum vibration amplitude from the vibration amplitudes of the compressor shutdown under multiple mechanical angles to be tested, and determining the target angle range based on the mechanical angle corresponding to the minimum vibration amplitude, the shutdown vibration of the compressor can be reduced when the mechanical angle of the rotor runs to the target angle range at a preset operating frequency and stops.
[0081] In one embodiment, when the compressor stops in a non-fault scenario, controlling the compressor to stop according to the second current operating frequency may include: controlling the compressor to stop when the second current operating frequency is less than a preset operating frequency.
[0082] For example, when the compressor of the air conditioner outdoor unit or the refrigerator compressor receives a shutdown command without any fault, the shutdown vibration of the compressor is small at the preset operating frequency. If the second current operating frequency of the compressor is less than the preset operating frequency, the shutdown vibration of the compressor will be smaller when it is shut down immediately, and the compressor can be controlled to shut down immediately. In this way, the vibration of the compressor when it is shut down can be effectively reduced, and the compressor does not need to be shut down after the operating frequency is reduced to 0, which effectively shortens the time required for the compressor to shut down.
[0083] Through the control method for the compressor provided by the present invention, in response to receiving a triggered stop instruction, the scenario of the triggering stop instruction is determined; from a plurality of preset stop methods, a target stop method corresponding to the scenario is determined; the compressor is controlled to shut down according to the target stop method, and the compressor can be flexibly shut down according to different scenarios of the triggering stop instruction, so that the shutdown method of the compressor matches the scenario of the triggering stop instruction, thereby ensuring the safety of the compressor.
