In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0057] During the operation of the existing air conditioner, there are the following problems in the communication between the indoor and outdoor units: 1. When the electric heating device in the indoor unit of the air conditioner is turned on and the current passing through the indoor and outdoor connection wires is too large, it is easy to introduce external interference, resulting in an increase in the communication error rate. 2. When the operating frequency of the compressor in the outdoor unit of the air conditioner is too high, it is easy to introduce interference into the communication circuit, resulting in an increase in the communication error rate. When the error rate is too high, it will cause the communication to malfunction and stop, greatly affecting the user experience. To solve the above technical problems, the present invention proposes a method for self-regulating the strong electricity communication of an air conditioner.

[0058] Figure 1 is a schematic flowchart of a control method for an air conditioner 100 according to an embodiment of the present invention, and in combination with Figures 2 - 7 , an embodiment of the present invention provides a control method for an air conditioner 100, which may include the following steps:

[0059] S100, obtain the communication error rates of the indoor unit and the outdoor unit;

[0060] S200, compare the communication error rate with a preset error rate threshold, where the preset error rate threshold is the limit value of the error rate that the air conditioner can allow;

[0061] S300, adjust the heating power of the electric heating device 130 and / or adjust the frequency of the compressor 120 according to the comparison result.

[0062] When the communication error rate is less than the preset error rate threshold, it can be determined that the error rate of the air conditioner is within the allowable range, and the air conditioner can communicate normally. At this time, the heating power of the electric heating device 130 and the frequency of the compressor 120 in step S300 remain unchanged. When the communication error rate is greater than or equal to the preset error rate threshold, it can be determined that the communication error rate of the air conditioner exceeds the limit value. Since the heating power of the electric heating device is too large, the current passing through the communication line is too large, which is likely to introduce external interference and cause a high error rate. When the frequency of the compressor is too high, it is easy to introduce interference into the communication circuit and cause the communication error rate to increase. Therefore, reducing the heating power of the electric heating device 130 or reducing the operating frequency of the compressor can both reduce the communication error rate. At this time, step S300 includes the following three situations: 1. Reducing the heating power of the electric heating device 130; 2. Reducing the frequency of the compressor 120; 3. Reducing the heating power of the electric heating device 130 and reducing the frequency of the compressor 120.

[0063] Therefore, during the operation of the air conditioner, by comparing the communication error rates of the indoor unit and the outdoor unit with the preset error rate threshold, it can be determined whether the error rate exceeds the limit value. According to the comparison result, the adjustment methods of the electric heating device 130 and the compressor 120 are determined to make the communication error rate less than the preset error rate threshold, so that the air conditioner is always in a normal communication state. Thus, the present invention can improve the communication problem between the indoor and outdoor units without shutting down the air conditioner, effectively avoid the problem of communication failure shutdown caused by a high communication error rate, greatly improve the user experience, enhance the operation stability of the air conditioner, and achieve the purpose of improving the user experience.

[0064] As Figure 2 shown, in some optional embodiments of the present invention, the control method of the air conditioner further includes the following steps:

[0065] S401, obtaining the indoor environmental temperature and the target temperature;

[0066] S402, obtaining the preset error rate threshold according to the temperature difference between the indoor environmental temperature and the target temperature.

[0067] The temperature difference between the indoor environmental temperature and the target temperature = |indoor environmental temperature - target temperature|, that is to say, the temperature difference between the indoor environmental temperature and the target temperature is the absolute value of the difference between the indoor environmental temperature and the target temperature.

[0068] Since the main function of an air conditioner is heat exchange to adjust the indoor environmental temperature to the target temperature that provides the best user experience, the difference between the indoor environmental temperature and the target temperature can most intuitively reflect the user's temperature perception. The better the communication effect, the closer the indoor environmental temperature is to the target temperature. When the difference between the indoor environmental temperature and the target temperature is too large, which greatly affects the user experience, it indicates that the current communication effect is poor and the communication error rate is high. At this time, the corresponding communication error rate is the preset error rate threshold. In this embodiment, by determining the preset error rate threshold according to the difference between the indoor environment and the target temperature, the communication effect between the indoor and outdoor units can be judged more intuitively, and the error rate threshold can be obtained more conveniently and directly.

[0069] In some alternative embodiments of the present invention, there is a positive correlation between the temperature difference between the indoor environmental temperature and the target temperature and the preset error rate threshold. Specifically, the larger the temperature difference between the indoor environmental temperature and the target temperature, the worse the communication effect, and the larger the preset error rate threshold; conversely, the smaller the temperature difference between the indoor environmental temperature and the target temperature, the better the communication effect, and the smaller the preset error rate threshold. That is to say, when the temperature difference between the indoor environmental temperature and the target temperature is larger, the difference between the indoor environmental temperature and the target temperature is greater. At this time, a higher heat exchange efficiency is required and the precision requirement is relatively lower, and a larger error rate threshold can be allowed to ensure the heat exchange effect of the air conditioner, improve the product performance, and improve the user experience faster; when the temperature difference between the indoor environmental temperature and the target temperature is smaller, the indoor environmental temperature is closer to the target temperature, and a higher precision is required. At this time, the limit value of the error rate is correspondingly smaller to make the indoor environmental temperature closer to the target temperature value and improve the user's temperature experience. By using the method of this embodiment, the heat exchange effect of the air conditioner and the communication effect between the indoor and outdoor units can be better balanced, thereby further improving the user's usage experience.

[0070] In some alternative embodiments of the present invention, a mapping relationship table between the temperature difference and the preset error rate threshold is pre-stored in the air conditioner. This mapping relationship indicates the limit value of the error rate that the air conditioner can tolerate when the temperature difference is in different ranges. Step S402, obtaining the preset error rate threshold according to the temperature difference between the indoor environmental temperature and the target temperature includes: determining the preset error rate threshold corresponding to the current temperature difference according to the mapping relationship table between the temperature difference and the preset error rate threshold. By using the control method of this embodiment, the preset error rate threshold can be obtained quickly and accurately, thereby improving the control accuracy.

[0071] In some alternative embodiments of the present invention, a mapping relationship table of temperature difference - fault tolerance mode - preset error rate threshold is pre - stored in the air conditioner. Step S402, the obtaining of the preset error rate threshold according to the temperature difference between the indoor environmental temperature and the target temperature includes: determining the fault tolerance mode and the preset error rate threshold corresponding to the current temperature difference according to the mapping relationship table of temperature difference - fault tolerance mode - preset error rate threshold. By using the control method of this embodiment, the preset error rate threshold can be obtained quickly and accurately, thereby improving the control accuracy.

[0072] The mapping relationship table of temperature difference - fault tolerance mode - preset error rate threshold can be as shown in Table 1 below:

[0073] Table 1

[0074]

[0075] Among them, the temperature differences corresponding to the first interval, the second interval, and the third interval gradually decrease, and the first threshold > the second threshold > the third threshold.

[0076] Furthermore, the division of the first interval, the second interval, and the third interval is not fixed, and the corresponding first threshold, second threshold, and third threshold are not fixed values either, and all can be set according to the model of the air conditioner.

[0077] For example, the first interval can be (5, 10], the first threshold can be 70%, and the first fault tolerance mode is the high - fault tolerance mode; the second interval can be (3, 5], the second threshold can be 50%, and the second fault tolerance mode is the medium - fault tolerance mode; the second interval can be [0, 3], the first threshold can be 20%, and the third fault tolerance mode is the low - fault tolerance mode.

[0078] In some alternative embodiments of the present invention, the obtaining of the preset error rate threshold according to the temperature difference between the indoor environmental temperature and the target temperature includes: obtaining the fault tolerance mode of the air conditioner according to the temperature difference between the indoor environmental temperature and the target temperature, and obtaining the preset error rate threshold corresponding to the fault tolerance mode. By using the control method of this embodiment, the fault tolerance mode and the preset error rate threshold corresponding to the above - mentioned temperature difference can be obtained quickly and accurately, thereby improving the control accuracy.

[0079] Furthermore, the method of obtaining the fault-tolerant mode of the air conditioner according to the temperature difference between the indoor ambient temperature and the target temperature, and obtaining the preset bit error rate threshold corresponding to the fault-tolerant mode, includes: when the temperature difference between the indoor ambient temperature and the target temperature is in a first interval, the fault-tolerant mode is the first fault-tolerant mode, and the preset bit error rate threshold is the first threshold; when the temperature difference between the indoor ambient temperature and the target temperature is in a second interval, the fault-tolerant mode is the second fault-tolerant mode, and the preset bit error rate threshold is the second threshold; when the temperature difference between the indoor ambient temperature and the target temperature is in a third interval, the fault-tolerant mode is the third fault-tolerant mode, and the preset bit error rate threshold is the third threshold; wherein, the temperature difference corresponding to the first interval, the second interval, and the third interval gradually decreases, and the first threshold>the second threshold>the third threshold.

[0080] In some optional embodiments of the present invention, step S300, adjusting the heating power of the electric heating device and / or adjusting the frequency of the compressor according to the comparison result, includes: the priority of adjusting the heating power of the electric heating device is higher than the priority of the frequency of the compressor.

[0081] In this embodiment, it is preferred to adjust the communication bit error rate of the indoor unit and the outdoor unit by adjusting the heating power of the electric heating device, so that the communication bit error rate is lower than the preset bit error rate threshold; if the communication bit error rate of the indoor unit and the outdoor unit is lower than the preset bit error rate threshold after adjusting the heating power of the electric heating device, there is no need to adjust the frequency of the compressor. This can improve the system stability of the air conditioner, ensure the heat exchange effect of the air conditioner, and further improve the user experience.

[0082] In some optional embodiments of the present invention, the step of adjusting the heating power of the electric heating device according to the comparison result includes: if the communication bit error is greater than or equal to the preset bit error rate threshold, gradually reducing the heating power of the electric heating device, and in the process of reducing the heating power, if the communication bit error rate is less than the preset bit error rate threshold, controlling the electric heating device to maintain the current heating power. This embodiment can maintain the heat exchange effect of the air conditioner as much as possible while reducing the communication bit error rate of the indoor unit and the outdoor unit.

[0083] In some optional embodiments of the present invention, in step S300, the step of adjusting the heating power of the electric heating device according to the comparison result includes: if the communication bit error is greater than or equal to the preset bit error rate threshold, directly reducing the heating power of the electric heating device to zero, that is, turning off the electric heating device. Compared with the above-mentioned method of gradually reducing the heating power of the electric heating device, the method of directly turning off the electric heating device can quickly reduce the communication bit error rate between the indoor unit and the outdoor unit.

[0084] Further, the control method of the air conditioner further includes: if the heating power decreases to zero and the communication error rate is less than the preset error rate threshold, it indicates that the reason for the high communication error rate is not the excessive power of the heating device. At this time, it is determined as a communication line fault, facilitating the user to timely maintain the communication line to avoid the subsequent frequent occurrence of a high communication error rate, which affects the user experience.

[0085] Furthermore, when it is determined as a communication line fault, a prompt message of "The connection line needs to be upgraded" is output. Still further, the prompt message of "The connection line needs to be upgraded" is output to the air conditioner display screen or the mobile phone app.

[0086] As Figure 3 shown, in some alternative embodiments of the present invention, step S300, adjusting the heating power of the electric heating device and / or adjusting the frequency of the compressor according to the comparison result, includes the following steps:

[0087] S301, if the communication error is greater than or equal to the preset error rate threshold, determine whether the electric heating device is turned on; if so, execute S302; if not, execute S303;

[0088] S302, reduce the heating power of the electric heating device; if the heating power decreases to zero and the communication error rate is still greater than or equal to the preset error rate threshold, execute S303 after a preset time or immediately;

[0089] S303, adjust the frequency of the compressor.

[0090] In this embodiment, the preset time can be set as needed. For example, the preset time can be 3 minutes. In this embodiment, when the communication error is greater than or equal to the preset error rate threshold, the communication error is preferentially reduced by reducing the heating power of the electric heating device to improve the communication effect between the indoor unit and the outdoor unit. When the electric heating device is not started or the communication error is still greater than or equal to the preset error rate threshold after the heating device is turned off, the communication error rate is reduced by adjusting the compressor power to maintain the system stability of the air conditioner as much as possible and ensure the heat exchange effect of the air conditioner.

[0091] Further, in some alternative embodiments of the present invention, as Figure 4 shown, S303, adjusting the frequency of the compressor includes the following steps:

[0092] S3031, determine whether the frequency of the compressor is greater than or equal to the frequency threshold; if so, execute S302; if not, execute S303;

[0093] S3032, reduce the frequency of the compressor;

[0094] S3033, determine as a communication line fault.

[0095] Further, in step S3032, reducing the compressor frequency includes: controlling the compressor frequency to decrease by a set frequency value.

[0096] In this embodiment, the frequency threshold can be set according to the model of the air conditioner. For example, the frequency threshold can be 60 Hz. The set frequency value can be set according to the model of the compressor. For example, the set frequency value can be 10 Hz.

[0097] In this embodiment, if the compressor frequency is greater than or equal to the frequency threshold, it indicates that the compressor frequency is very high at this time, and it is easy to introduce interference into the communication circuit, resulting in an increase in the communication error rate. Therefore, the communication error rate is reduced by reducing the compressor frequency. If the compressor frequency is less than the frequency threshold, the compressor frequency is relatively small at this time, and the current compressor frequency is not the reason for the high communication error rate. Therefore, it is determined that there is a communication line fault, so that the user can promptly maintain the communication line, thereby avoiding the frequent occurrence of a high communication error rate and affecting the user experience.

[0098] Furthermore, when it is determined that there is a communication line fault, a prompt message of "The connection line needs to be upgraded" is output. Even further, the prompt message of "The connection line needs to be upgraded" is output to the air conditioner display screen or the mobile phone app.

[0099] As Figure 5 shown, in some alternative embodiments of the present invention, a mapping relationship table of temperature difference - fault tolerance mode - preset error rate threshold is pre - stored in the air conditioner. The control method of the air conditioner includes the following steps:

[0100] S1, obtaining the communication error rate of the indoor unit and the outdoor unit;

[0101] S2, obtaining the indoor environmental temperature and the target temperature;

[0102] S3, according to the mapping relationship table of temperature difference - fault tolerance mode - preset error rate threshold, determining the fault tolerance mode and the preset error rate threshold corresponding to the temperature difference between the indoor environmental temperature and the target temperature;

[0103] S4, determining whether the current communication error rate is greater than or equal to the preset error rate threshold; if so, execute S5;

[0104] S5, determining whether the electric heating device is turned on; if so, execute S6; if not, execute S7;

[0105] S6, disconnecting the relay of the electric heating device to turn off the electric heating device;

[0106] S7. After a preset time, determine whether the current communication error rate is greater than or equal to a preset error rate threshold; if so, execute S8; if not, execute S9;

[0107] S8. Determine whether the frequency of the compressor is greater than or equal to a frequency threshold; if so, execute S10; if not, execute S9;

[0108] S9. Output a prompt message of "The connection line needs to be upgraded";

[0109] S10. Control the frequency of the compressor to decrease by a set frequency value;

[0110] S11. Determine whether the current communication error rate is still greater than or equal to the preset error rate threshold; if so, execute S8; if not, execute S9.

[0111] The present invention provides an air conditioner strong electricity communication self - adjustment method. According to the difference between the indoor environmental temperature and the target temperature, the current operation mode (high - fault - tolerance mode, medium - fault - tolerance mode, low - fault - tolerance mode) is selected. And when the communication error rate between the indoor and outdoor units exceeds the limit value tolerated by the current mode, the start - stop of the electric heating and the rise and fall of the compressor frequency are adaptively modulated to solve the problem of the communication error rate. In this embodiment, without shutting down the machine, the communication problem between the indoor and outdoor units is adaptively improved, greatly improving the user experience.

[0112] As Figure 6 shown, an embodiment of the present invention also provides an air conditioner 100. The air conditioner 100 includes a controller 110. The controller 110 includes a memory 111, a processor 112, and a computer program 210 stored on the memory 111 and running on the processor 112. And when the processor 112 executes the computer program 210, the steps of the control method of the air conditioner 100 in any of the above - mentioned embodiments or combinations of embodiments are realized.

[0113] The controller 110 can be directly set inside the air conditioner 100, is wired - connected to the electrical components related to the air conditioner 100, and realizes the steps of the control method of the air conditioner 100. The controller can also be set on a cloud server, is wired or wirelessly connected to the electrical components related to the air conditioner 100, and realizes the steps of the control method of the air conditioner 100.

[0114] The air conditioner 100 can be a household air conditioner, a central air conditioner, a multi - connected air conditioner, etc.
