[0037] Figure 3 It is a schematic structural diagram of the electronic device provided by the present invention. Specific embodiments

[0038] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0039] The protection control method, protection control device and air conditioner of the air conditioner proposed by the present invention will be described below with reference to the drawings. Among them, before the detailed description of the embodiments of the present invention, the entire application scenario will be described first. The protection control method, protection control device, electronic device and computer-readable storage medium of the air conditioner in the embodiments of the present invention can be applied not only to the local area of the air conditioner, but also to the cloud platform in the Internet field, or the cloud platform in other types of Internet fields, or can also be applied to third-party devices. Among them, the third-party devices may include various different types such as mobile phones, tablet computers, notebooks, in-vehicle computers and other intelligent terminals.

[0040] Only the protection control method applicable to the air conditioner will be described below as an example. It should be understood that the protection control method in the embodiments of the present invention can also be applicable to the cloud platform and third-party devices.

[0041] It should also be noted that the protection control method of the air conditioner proposed by the present invention is universal, that is, this method is applicable to both cooling and heating of the air conditioner in a low-temperature environment or a high-temperature environment.

[0042] As Figure 1 shown, the protection control method of the air conditioner according to the first aspect embodiment of the present invention includes:

[0043] Step S1, obtaining the outdoor ambient temperature and the current operating mode of the air conditioner;

[0044] Step S2, when the outdoor ambient temperature and / or the current operating mode meet the set conditions, controlling the air conditioner to perform a current compensation operation, and obtaining a current compensation value of the air conditioner during operation based on the outdoor ambient temperature;

[0045] Step S3, correcting the set overcurrent protection value of the air conditioner according to the current compensation value, and obtaining the corrected actual overcurrent protection value;

[0046] Step S4: Obtain the actual current value of the air conditioner during operation, and perform overcurrent protection on the air conditioner based on the actual current value and the actual overcurrent protection value.

[0047] For the protection control method of the air conditioner according to the embodiment of the present invention, its specific working process is as follows: First, obtain the specific magnitude of the outdoor environmental temperature where the outdoor unit of the air conditioner is located, and obtain the current operating mode of the air conditioner. Subsequently, the controller analyzes and judges the outdoor environmental temperature and the current operating mode of the air conditioner. When it is determined that the outdoor environmental temperature and / or the current operating mode meet the set conditions, the controller controls the air conditioner to perform current compensation operation, that is, compensate the current value during the operation of the air conditioner to ensure the stability of the air conditioner operation. At this time, the specific magnitude of the current compensation value for compensating the current in the current compensation operation will be determined by the controller according to the specific magnitude of the outdoor environmental temperature.

[0048] After obtaining the current compensation value, the controller will correct the set overcurrent protection value of the air conditioner to obtain the actual overcurrent protection value that conforms to the current situation. It can be understood that the set overcurrent protection value is the set value pre-stored in the air conditioner system, and the actual overcurrent protection value is the result obtained by the controller correcting the set overcurrent protection value based on the current compensation value. This actual overcurrent protection value takes into account the influence of the current compensation value generated by the current compensation operation on the overcurrent protection control, so that the air conditioner can still accurately perform overcurrent protection control after performing the current compensation operation to avoid faults such as burnout and damage caused by excessive current in the air conditioner.

[0049] After that, the controller will perform overcurrent protection control on the air conditioner based on the previously obtained actual current value and actual overcurrent protection value. Specifically, the controller will compare the magnitudes of the actual current value and the actual overcurrent protection value, and select different overcurrent protection means to perform overcurrent protection on the air conditioner according to different comparison results. Among them, the overcurrent protection means include, but are not limited to, means such as performing a frequency reduction operation on the compressor, performing a frequency reduction operation on the compressor, or controlling the compressor to stop. The present invention does not make special limitations here, as long as the overcurrent protection means can achieve overcurrent protection.

[0050] In the related art, during the startup or operation of existing air conditioners, sometimes due to excessive current during frequency reduction, the air conditioner may short-circuit or suddenly stop. And there are no effective current protection measures in the related art, so that the air conditioner cannot effectively protect itself in the face of overcurrent situations, and the operation process of the air conditioner is unstable and prone to failure.

[0051] Therefore, in order to solve the technical defects existing in the above related technologies, the present invention proposes a protection control method for an air conditioner. This method uses current compensation operations during the actual operation of the air conditioner to ensure the stable operation of the air conditioner, and takes into account the influence of the current compensation value in overcurrent protection control. The set overcurrent protection value is corrected using the current compensation value to obtain the actual overcurrent protection value, and overcurrent protection is performed on the air conditioner based on the actual overcurrent protection value, so that the air conditioner can still accurately perform overcurrent protection control after performing the current compensation operation, to avoid failures such as burning and damage due to excessive air conditioner current, and effectively protect the normal operation of the air conditioner.

[0052] According to some embodiments of the present invention, in the step of correcting the set overcurrent protection value of the air conditioner according to the current compensation value and obtaining the corrected actual overcurrent protection value:

[0053] The corrected actual overcurrent protection value is greater than or equal to the sum of the set overcurrent protection value and the current compensation value.

[0054] For example, in the cooling mode, the power limit current at which the power supply current needs to enter the frequency reduction point is the pre-set set overcurrent protection value. After the air conditioner performs the current compensation operation, the actual overcurrent protection value is the above set overcurrent protection value plus the current compensation value.

[0055] In addition, the determination of the actual overcurrent protection value in the heating mode is similar to the above embodiment, and the present invention will not elaborate here.

[0056] According to some embodiments of the present invention, the step of controlling the air conditioner to perform current compensation operations according to the outdoor environmental temperature and the current operating mode meeting the set conditions specifically includes:

[0057] Controlling the air conditioner to perform current compensation operations according to the outdoor environmental temperature being greater than or equal to the set compensation temperature;

[0058] And / or, according to the current operating mode being the cooling mode and the frequency of the compressor of the air conditioner being less than the maximum set frequency, controlling the air conditioner to perform current compensation operations.

[0059] In this embodiment, performing the current compensation operation requires the air conditioner to meet certain conditions. Specifically, when the outdoor environmental temperature is less than the set compensation temperature, the air conditioner is in the heating mode, or the air conditioner is in the fixed-frequency maximum cooling mode, the air conditioner does not perform the current compensation operation, and when the outdoor environmental temperature is greater than or equal to the set compensation temperature, or the air conditioner is currently in the cooling mode with the compressor frequency less than the maximum set frequency, the air conditioner performs the current compensation operation.

[0060] It can be understood that when the set conditions are met to perform the current compensation operation, the air conditioner can operate more stably.

[0061] Further, the step of obtaining the current compensation value of the air conditioner during operation based on the outdoor ambient temperature specifically includes:

[0062] When the outdoor ambient temperature is within the first range, determine that the current compensation value is the first set compensation value;

[0063] When the outdoor ambient temperature is within the second range, determine that the current compensation value is the second set compensation value;

[0064] Wherein, the minimum value within the second range is greater than or equal to the set compensation temperature, the first range is greater than the second range, and the first set compensation value is greater than the second set compensation value.

[0065] In this embodiment, the current compensation value has a positive correlation with the outdoor ambient temperature, that is, when the detected outdoor ambient temperature is higher, the current compensation value is larger.

[0066] According to some embodiments of the present invention, the step of performing overcurrent protection on the air conditioner according to the actual current value and the actual overcurrent protection value specifically includes:

[0067] When the actual current value is greater than the actual overcurrent protection value, control the compressor of the air conditioner to stop, and control the alarm device of the air conditioner to give a fault alarm.

[0068] In this embodiment, when it is detected that the actual current value of the power supply current is greater than the actual overcurrent protection value, it means that the current power supply current is too large, which may cause overcurrent and lead to the risk of air conditioner short - circuit or sudden stop. Therefore, when the above - mentioned situation occurs, the controller will directly control the compressor of the air conditioner to stop for a set duration, and then will also control the alarm device of the air conditioner to give a fault alarm.

[0069] For example, when it is detected that the actual current value is greater than the actual overcurrent protection value, the compressor stops for five seconds, and the fault light of the air conditioner starts to flash to remind the user of the occurrence of the fault.

[0070] According to some other embodiments of the present invention, the step of performing overcurrent protection on the air conditioner according to the actual current value and the actual overcurrent protection value specifically includes:

[0071] When the actual current value is less than the actual overcurrent protection value, obtain the difference between the actual overcurrent protection value and the actual current value;

[0072] When it is determined that the difference between the actual overcurrent protection value and the actual current value is less than the set current value, control the compressor of the air conditioner to perform a frequency - reduction operation.

[0073] In this embodiment, when it is detected that the actual current value of the power supply current is less than the actual overcurrent protection value, the air conditioner does not have an overcurrent phenomenon at present. However, when the actual current value is greater than the actual overcurrent protection value minus the set current value, that is, the actual current value is relatively close to the actual overcurrent protection value. Therefore, if the actual current value continues to increase, the air conditioner will eventually still have an overcurrent and cause the air conditioner to short-circuit or stop suddenly. Therefore, when the above situation occurs, the controller will directly control the compressor of the air conditioner to perform a frequency reduction operation, thereby reducing the actual current value of the power supply circuit, avoiding the continuous increase of the actual current value, avoiding the occurrence of overcurrent phenomenon, and thus ensuring the normal operation of the air conditioner.

[0074] Further, the step of controlling the compressor of the air conditioner to perform a frequency reduction operation specifically includes: controlling the compressor to reduce the frequency by a set frequency every set time period.

[0075] For example, the set current value can be 2A. When the actual current value is less than the actual overcurrent protection value and the actual current value of the power supply current is greater than the actual overcurrent protection value minus 2A, the air conditioner performs a frequency reduction operation. The frequency reduction operation is to control the compressor to reduce the frequency by one hertz every five seconds.

[0076] For another example, when the actual current value is less than the actual overcurrent protection value and the actual current value of the power supply current is greater than the actual overcurrent protection value minus 1A, the air conditioner remains in its current state unchanged.

[0077] Further, this method also includes the phase current protection control of the compressor. Specifically, this control includes: obtaining the magnitude of the phase current of the compressor and performing phase current protection control on the compressor according to the comparison between the phase current and the set phase current protection value.

[0078] For example, when the phase current of the compressor is greater than the first set phase current protection value, the compressor does not perform a frequency increase operation and remains in its current state unchanged; when the phase current of the compressor is greater than the second set phase current protection value, the compressor performs a frequency reduction operation, that is, the compressor reduces the frequency by one hertz every second; when the phase current of the compressor is greater than the third set phase current protection value, the compressor stops for five seconds and the fault light flashes 25 times. At this time, only the outdoor unit displays and does not send a fault confirmation bit to the indoor unit.

[0079] The first set phase current protection value is less than the second set phase current protection value, and the second set phase current protection value is less than the third set phase current protection value. The present invention does not make special limitations on the specific magnitudes of the first set phase current protection value, the second set phase current protection value, and the third set phase current protection value. The above phase current protection values can be specifically limited according to the specific usage scenarios.

[0080] The protection control device of the air conditioner provided by the present invention will be described below.
