[0029] The term "corresponding" can refer to an association or binding relationship. A and B correspond to each other means that there is an association or binding relationship between A and B.

[0030] In the embodiments of the present disclosure, the smart home appliance refers to a home appliance product formed by introducing microprocessors, sensor technology, network communication technology into home appliance devices, having the characteristics of intelligent control, intelligent perception and intelligent application. The operation process of the smart home appliance often depends on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, the smart home appliance can form a smart home system by connecting other smart home appliances, and realize linkage control and collaborative management of multiple smart home appliances. In the embodiments of the present disclosure, the smart home appliance includes a smart air conditioner.

[0031] At present, because the refrigerant R22 has the problem of destroying the ozone layer, more and more air conditioners begin to use more environmentally friendly refrigerants such as R32, R290, etc. to replace R22. However, the above-mentioned refrigerants have the characteristics of flammability and explosiveness. Under certain concentration conditions, if they come into contact with air and encounter an open flame, they may cause combustion or even explosion. The related technology proposes a control method of an air conditioner. When the air conditioner is running, the leak detector detects that there is a flammable refrigerant leakage around. The outdoor unit of the air conditioner is powered off, the control program of the air conditioner is locked, the air conditioner does not process the received instructions, the air conditioner displays a fault code and the buzzer alarms; the indoor fan motor of the air conditioner runs at high speed, the ventilation motor starts, and after t2 time, the entire air conditioner is powered off.

[0032] The related technology only discharges the flammable refrigerant when it leaks. However, when other household appliances in the room malfunction or safety hazards are identified, the flammable refrigerant stored in the indoor unit of the air conditioner also poses a risk and is prone to cause secondary damage, which is not conducive to the safety of users at home.

[0033] In combination Figure 1 As shown in the drawings, the embodiments of the present disclosure provide a smart air conditioner, which includes a compressor 10, an outdoor heat exchanger 20, a throttling valve 30 and an indoor heat exchanger 40. The compressor 10, the outdoor heat exchanger 20, the throttling valve 30 and the indoor heat exchanger 40 are connected in sequence through a refrigerant pipeline to form a refrigerant circulation loop.

[0034] Optionally, the smart air conditioner further includes an outdoor fan 50 and an indoor fan 60. The outdoor fan 50 is arranged relative to the outdoor heat exchanger 20. The indoor fan 60 is arranged relative to the indoor heat exchanger 40.

[0035] The smart air conditioner provided by the embodiments of the present disclosure can perform refrigeration, air supply or standby operation according to user needs, thereby ensuring the user experience.

[0036] Optionally, the smart air conditioner further comprises a one-way valve 70. The one-way valve 70 is arranged on the refrigerant pipeline between the outdoor heat exchanger 20 and the compressor 10, so as to limit the one-way flow of the refrigerant from the compressor 10 to the outdoor heat exchanger 20. Thus, it is possible to prevent the flammable refrigerant from flowing back to the indoor side after the smart air conditioner executes the refrigerant transfer scheme, which is conducive to ensuring the safety of the smart air conditioner.

[0037] In combination Figure 2 As shown in the drawings, the embodiment of the present disclosure provides a method for controlling a smart air conditioner, comprising:

[0038] In S201, the processor determines a risk response scheme of the smart air conditioner in response to a control instruction of a safety linkage mode.

[0039] In S202, when the risk response scheme is a refrigerant transfer scheme, the processor controls the smart air conditioner to run in a cooling mode and controls the throttling valve to be closed.

[0040] In S203, the processor controls the compressor, the indoor fan and the outdoor fan to run for a preset time length and then to be closed, so as to transfer the refrigerant from the indoor side to the outdoor side.

[0041] By using the method for controlling a smart air conditioner provided by the embodiment of the present disclosure, when the smart air conditioner receives a control instruction of a safety linkage mode, a specific risk response scheme is first determined to control the smart air conditioner to make adaptive adjustment so as to reasonably avoid risks. When the risk response scheme is a refrigerant transfer scheme, the smart air conditioner runs in a cooling mode and the throttling valve is closed to cut off the path of the flammable refrigerant flowing from the outdoor side to the indoor side. Then, the compressor, the indoor fan and the outdoor fan run for a preset time length and then stop, so as to gradually transfer the flammable refrigerant from the indoor side to the outdoor side through the refrigerant pipeline. Thus, the embodiment of the present disclosure can transfer the flammable refrigerant stored in the indoor unit of the smart air conditioner to the outdoor side in advance when there is a safety hazard in the indoor, so as to assist the smart air conditioner to avoid secondary damage before the indoor risk expands, which is conducive to ensuring the safety of the user at home.

[0042] In the embodiment of the present disclosure, the safety linkage mode refers to a centralized protection mode of a smart home system. The smart home system can link multiple smart home appliances in the indoor to realize the linkage control and collaborative management of the multiple smart home appliances. When a certain smart home appliance fails or identifies a safety hazard, the safety linkage mode of the smart home system is triggered, and the corresponding control instruction is sent to other smart home appliances, so that they can respond in advance to avoid secondary damage, which is conducive to reducing the indoor risk.

[0043] Optionally, the processor controls the throttling valve to close, comprising: the processor determines a target closing rate of the throttling valve according to the safety linkage mode; and the processor controls the throttling valve to close at the target closing rate. In this way, the embodiments of the present disclosure can reasonably set the target closing rate of the throttling valve in combination with the safety linkage mode, ensure that the indoor side combustible refrigerant can be transferred before the indoor danger expands, and reduce the adverse effects of too fast closing on the intelligent air conditioner.

[0044] Optionally, the processor determines the target closing rate of the throttling valve according to the safety linkage mode, comprising: the processor determines the target closing rate of the throttling valve according to the trigger object and / or the trigger cause of the safety linkage mode. In this way, the embodiments of the present disclosure can determine the trigger object and / or the trigger cause of the safety linkage mode, and then analyze the degree of association or the degree of harm of the intelligent air conditioner, so as to more reasonably set the target closing rate of the throttling valve, ensure that the indoor side combustible refrigerant can be transferred before the indoor danger expands, and reduce the adverse effects of too fast closing on the intelligent air conditioner.

[0045] Optionally, after the processor controls the intelligent air conditioner to run in the cooling mode and controls the throttling valve to close, the processor further controls the compressor to run at a high frequency; and / or, the processor controls the indoor fan to run at a high wind speed; and / or, the processor controls the outdoor fan to run at a high wind speed. In this way, after the embodiments of the present disclosure control the intelligent air conditioner to run in the cooling mode, the compressor is further controlled to run at a high frequency, and / or the indoor fan is controlled to run at a high wind speed, and / or the outdoor fan is controlled to run at a high wind speed. Thus, the discharge speed of the combustible refrigerant from the indoor side to the outdoor side can be accelerated, and the intelligent air conditioner can further ensure that the combustible refrigerant is transferred before the indoor danger expands, which is beneficial to avoiding secondary damage in time.

[0046] Optionally, the processor controls the compressor to run at a high frequency, comprising: the processor determines a target running frequency and a target limited current of the intelligent air conditioner; the processor controls the compressor to run at the target running frequency, and detects a real-time working current of the intelligent air conditioner at the target running frequency; and the processor adjusts the running frequency of the compressor according to the real-time working current and the target limited current. In this way, the embodiments of the present disclosure can first control the compressor to run at a higher target running frequency, then detect the real-time working current at the target running frequency, and compare the size relationship between the real-time working current and the target limited current, and then reasonably adjust the running frequency of the compressor, so that the compressor can execute the refrigerant transfer scheme more safely.

[0047] Optionally, the processor determines the target operating frequency and the target current limiting frequency of the smart air conditioner according to the safety linkage mode. In this way, the embodiments of the present disclosure can reasonably set the target operating frequency and the target current limiting frequency of the smart air conditioner in combination with the safety linkage mode, while controlling the high-frequency operation of the compressor to speed up the transfer speed of the flammable refrigerant, and also guarantee the safety of the smart air conditioner when the refrigerant transfer scheme is executed.

[0048] Further, the processor can determine the target operating frequency and the target current limiting frequency of the smart air conditioner according to the trigger object and / or the trigger cause of the safety linkage mode. Specifically, in some embodiments, the two can be set in one-to-one correspondence by establishing a preset association relationship, such as matching the corresponding target operating frequency of the smart air conditioner according to the trigger object of the safety linkage mode, and matching the corresponding target current limiting frequency of the smart air conditioner according to the trigger cause of the safety linkage mode. In other embodiments, the two can also not be set in one-to-one correspondence, but be determined by comprehensive analysis, which is not specifically limited by the embodiments of the present disclosure. Therefore, the embodiments of the present disclosure can analyze the degree of association or the degree of harm of the smart air conditioner according to the trigger object and the trigger cause of the safety linkage mode, so as to more reasonably set the target operating frequency and the target current limiting frequency of the smart air conditioner, to improve the safety of the smart air conditioner when executing the refrigerant transfer scheme.

[0049] Optionally, the processor adjusts the operating frequency of the compressor according to the real-time working current and the target current limiting frequency, including: in the case that the real-time working current is greater than the target current limiting frequency, the processor reduces the operating frequency of the compressor; the processor detects the new real-time working current of the smart air conditioner after the operating frequency is reduced; in the case that the new real-time working current is less than or equal to the target current limiting frequency, the processor maintains the operating frequency of the compressor. In this way, the embodiments of the present disclosure can first control the compressor to operate at a higher target operating frequency, and then detect the real-time working current under the target operating frequency. When the real-time working current is greater than the target current limiting frequency, it indicates that the operating frequency of the compressor is too high at this time, and the smart air conditioner may have certain safety problems when executing the refrigerant transfer scheme in this state. Therefore, the processor appropriately reduces the operating frequency of the compressor, and re-detects the corresponding real-time working current, until the new real-time working current is less than or equal to the target current limiting frequency, at which time the execution of the refrigerant transfer scheme is not easy to cause safety problems of the smart air conditioner. Therefore, the embodiments of the present disclosure can control the high-frequency operation of the compressor to speed up the transfer speed of the flammable refrigerant, while also guaranteeing the safety of the smart air conditioner when executing the refrigerant transfer scheme.

[0050] Optionally, the processor determines the risk response scheme of the smart air conditioner, including: the processor determines the risk warning level of the smart air conditioner according to the safety linkage mode; and the processor determines the risk response scheme of the smart air conditioner according to the risk warning level of the smart air conditioner. In this way, the embodiments of the present disclosure can analyze the risk degree corresponding to the safety linkage mode, and then determine the risk warning level of the smart air conditioner, and determine the risk response scheme corresponding to the smart air conditioner accordingly, thereby facilitating the smart air conditioner to make adaptive adjustment to reasonably avoid risks.

[0051] Optionally, the processor determines the risk warning level of the smart air conditioner according to the safety linkage mode, including: the processor determines the risk warning level of the smart air conditioner according to the trigger object and / or trigger cause of the safety linkage mode. In this way, the embodiments of the present disclosure can determine the trigger object and / or trigger cause of the safety linkage mode, and then analyze the risk degree thereof with respect to the smart air conditioner, thereby being able to determine the risk warning level of the smart air conditioner at this time, so as to facilitate the smart air conditioner to make adaptive adjustment to reasonably avoid risks.

[0052] Specifically, in some embodiments, in the case that the trigger cause of the safety linkage mode is that other smart home appliances are tripped, the risk warning level of the smart air conditioner is determined to be a primary risk warning. In other embodiments, in the case that the trigger cause of the safety linkage mode is smoke alarm, the risk warning level of the smart air conditioner is determined to be a middle risk warning. In still other embodiments, in the case that the trigger cause of the safety linkage mode is fire alarm, the risk warning level of the smart air conditioner is determined to be a high risk warning. Thus, the embodiments of the present disclosure can reasonably determine the risk warning level corresponding to the smart air conditioner in combination with the trigger cause of the safety linkage mode, thereby facilitating the smart air conditioner to execute a suitable risk response scheme to reasonably avoid risks.

[0053] Optionally, the embodiments of the present disclosure can also set more risk warning levels, and are not limited to the above three risk warning levels. The risk warning level can also be reasonably set according to more trigger objects and / or trigger causes of the safety linkage mode, so as to accurately divide the risk degree thereof with respect to the smart air conditioner, which is not listed one by one here. Meanwhile, based on the above various risk warning levels, the smart air conditioner can set corresponding risk response schemes and make corresponding functional adjustments, thereby reasonably avoiding risks.

[0054] Optionally, the processor determines the risk response scheme of the smart air conditioner according to the risk warning level of the smart air conditioner, including: in the case that the risk warning level of the smart air conditioner is a primary risk warning, the processor determines that the risk response scheme of the smart air conditioner is a power-off protection scheme; or in the case that the risk warning level of the smart air conditioner is a medium risk warning, the processor determines that the risk response scheme of the smart air conditioner is a refrigerant transfer scheme; or in the case that the risk warning level of the smart air conditioner is a high risk warning, the processor determines that the risk response scheme of the smart air conditioner is a refrigerant isolation scheme. In this way, the embodiments of the present disclosure can set an adaptive risk response scheme for different risk warning levels, thereby facilitating the smart air conditioner to make adaptive adjustments to reasonably avoid risks. When the risk warning level is a primary risk warning, it indicates that the current risk is difficult to affect the smart air conditioner or the degree of harm to the smart air conditioner is low, at this time the smart air conditioner is relatively safe. Therefore, the embodiments of the present disclosure determine that the risk response scheme of the smart air conditioner at this time is a power-off protection scheme, which is beneficial to avoid subsequent risks by powering off the smart air conditioner in time. When the risk warning level is a medium risk warning, it indicates that the current risk may gradually expand and be transmitted to the smart air conditioner, and then cause a certain degree of secondary damage to the smart air conditioner, at this time the smart air conditioner is at considerable risk. Therefore, the embodiments of the present disclosure determine that the risk response scheme of the smart air conditioner at this time is a refrigerant transfer scheme, which is beneficial to protect the safety of users at home by transferring the flammable refrigerant stored in the indoor unit of the smart air conditioner to the outdoor side in advance to assist the smart air conditioner to avoid secondary damage before the indoor risk expands. When the risk warning level is a high risk warning, it indicates that the current risk is likely to have spread to the smart air conditioner and is about to cause serious secondary damage. Therefore, the embodiments of the present disclosure determine that the risk response scheme of the smart air conditioner at this time is a refrigerant isolation scheme, which is beneficial to avoid further expansion of the risk by quickly isolating the indoor refrigerant and the outdoor refrigerant to reduce the damage degree of the smart air conditioner.

[0055] Specifically, in some embodiments, the processor responds to the control instruction of the safety linkage mode and further analyzes the safety linkage mode to determine the triggering object and the triggering reason. Illustratively, when the triggering object is identified as a smart range hood and the triggering reason is a smoke detection alarm, the processor determines that the degree of harm to the smart air conditioner is relatively high, and there is a possibility of indoor fire and even flammable refrigerant combustion or explosion of the smart air conditioner, at this time the safety linkage mode is determined to be a medium safety mode, and the smart air conditioner needs to execute the refrigerant transfer scheme within a limited time to reasonably avoid risks.

[0056] To this end, the processor controls the intelligent air conditioner to run in the cooling mode, and controls the throttling valve to close at a speed of 20 steps / s, so that the transfer of the combustible refrigerant from the indoor side to the outdoor side can be completed faster, and the adverse effects of too fast closing of the throttling valve on the intelligent air conditioner can be reduced. At the same time, the processor controls the indoor fan to run at a high wind level, and controls the outdoor fan to run at a high wind level, and then controls the compressor to run at a high frequency of 66 Hz, so as to speed up the transfer of the combustible refrigerant as much as possible. In addition, in order to ensure the safety of the intelligent air conditioner when the refrigerant transfer scheme is executed, the processor continuously detects the real-time working current of the intelligent air conditioner. If the real-time working current under the high frequency of 66 Hz is greater than the target frequency limiting current 11 A, it indicates that there may be certain safety problems in the execution of the refrigerant transfer scheme by the intelligent air conditioner in this state. Therefore, the processor reduces the running frequency of the compressor at a speed of 0.33 Hz / s, and updates the real-time working current of the intelligent air conditioner. When the detected new real-time working current is less than or equal to the target frequency limiting current 11 A, the compressor no longer performs the frequency reduction operation, and the intelligent air conditioner continues to run at the running frequency at this time. After 80 s, the combustible refrigerant stored in the indoor unit of the intelligent air conditioner has been basically transferred to the outdoor side, and the processor controls the compressor, the indoor fan and the outdoor fan to be turned off, and the intelligent air conditioner is powered off. Thus, the embodiment can complete the transfer of the combustible refrigerant from the indoor side before the indoor danger expands, so as to assist the intelligent air conditioner to avoid secondary damage in time, and is beneficial to protect the safety of users at home.

[0057] In combination Figure 3 The embodiment of the present disclosure provides another method for controlling an intelligent air conditioner, comprising:

[0058] S301, in response to the control instruction of the safety linkage mode, the processor determines the risk warning level of the intelligent air conditioner according to the safety linkage mode.

[0059] S302, in the case that the risk warning level of the intelligent air conditioner is a primary risk warning, the processor determines that the risk response scheme of the intelligent air conditioner is a power-off protection scheme.

[0060] S303, in the case that the risk warning level of the intelligent air conditioner is a medium risk warning, the processor determines that the risk response scheme of the intelligent air conditioner is a refrigerant transfer scheme.

[0061] S304, the processor controls the intelligent air conditioner to run in the cooling mode, and controls the throttling valve to close.

[0062] S305, the processor controls the compressor, the indoor fan and the outdoor fan to run for a preset time length and then to be turned off, so as to transfer the refrigerant from the indoor side to the outdoor side.

[0063] S306, in the case that the risk warning level of the intelligent air conditioner is a high risk warning, the processor determines that the risk response scheme of the intelligent air conditioner is a refrigerant isolation scheme.

[0064] The method for controlling the smart air conditioner provided by the embodiment of the present disclosure is adopted. When the smart air conditioner receives the control instruction of the safety linkage mode, the risk degree corresponding to the safety linkage mode is first analyzed, and then the risk warning level of the smart air conditioner is determined, and the risk response scheme corresponding to the smart air conditioner is determined accordingly, thereby facilitating the smart air conditioner to make adaptive adjustment to reasonably avoid risks. When the risk warning level is the primary risk warning, the risk response scheme at this time is the power-off protection scheme. The smart air conditioner is powered off in time, thereby facilitating the avoidance of subsequent risks. When the risk warning level is the intermediate risk warning, the risk response scheme at this time is the refrigerant transfer scheme. The smart air conditioner operates in the refrigeration mode and closes the throttling valve to cut off the path of the flammable refrigerant flowing from the outdoor side to the indoor side. Then, the compressor, the indoor fan and the outdoor fan are continuously operated for a preset time length and then stopped, thereby being able to gradually transfer the flammable refrigerant from the indoor side to the outdoor side through the refrigerant pipeline. In this way, the embodiment of the present disclosure can discharge the flammable refrigerant stored in the indoor unit of the smart air conditioner to the outdoor side in advance when there is a safety hazard in the indoor, thereby assisting the smart air conditioner to avoid secondary damage before the indoor hazard expands, and facilitating to protect the safety of users at home. When the risk warning level is the high-level risk warning, the risk response scheme at this time is the refrigerant isolation scheme. By quickly isolating the indoor refrigerant and the outdoor refrigerant, the damage degree of the smart air conditioner can be reduced, thereby facilitating to avoid further expansion of the hazard.

[0065] Optionally, after the processor determines that the risk response scheme of the smart air conditioner is the power-off protection scheme, the method further includes: the processor controls the smart air conditioner to turn off the working power supply. In this way, the embodiment of the present disclosure can turn off the working power supply of the smart air conditioner to power off the smart air conditioner in time, thereby facilitating to avoid subsequent risks.

[0066] Optionally, after the processor determines that the risk response scheme of the smart air conditioner is the refrigerant isolation scheme, the method further includes: the processor controls the throttling valve to close at the maximum valve closing rate. In this way, the embodiment of the present disclosure can quickly close the throttling valve of the smart air conditioner to quickly isolate the indoor refrigerant and the outdoor refrigerant, thereby reducing the damage degree of the smart air conditioner, and facilitating to avoid further expansion of the hazard.

[0067] In combination with Figure 4 The embodiment of the present disclosure provides another method for controlling a smart air conditioner, which includes:

[0068] S401, the processor determines the risk response scheme of the smart air conditioner in response to the control instruction of the safety linkage mode.

[0069] S402, in the case where the risk response scheme is the refrigerant transfer scheme, the processor controls the smart air conditioner to operate in the refrigeration mode and controls the throttling valve to close.

[0070] S403, the processor controls the compressor, the inner fan and the outer fan to run for a preset time length and then to be turned off, so as to transfer the refrigerant from the indoor side to the outdoor side.

[0071] S404, the processor controls the smart air conditioner to start the power supply and controls the throttle valve to be fully opened in response to the release instruction of the safety linkage mode.

[0072] S405, the processor detects the current working current of the smart air conditioner.

[0073] S406, the processor determines the refrigerant leakage state of the smart air conditioner according to the current working current.

[0074] S407, in the case that the refrigerant leakage state is no refrigerant leakage, the processor controls the smart air conditioner to release the safety linkage mode.

[0075] S408, in the case that the refrigerant leakage state is refrigerant leakage, the processor controls the smart air conditioner to maintain the safety linkage mode.

[0076] The method for controlling the smart air conditioner provided by the embodiment of the present disclosure can first determine a specific risk response scheme when the smart air conditioner receives a control instruction of the safety linkage mode, so as to control the smart air conditioner to make adaptive adjustment and reasonably avoid risks. When the risk response scheme is a refrigerant transfer scheme, the smart air conditioner operates in the refrigeration mode and closes the throttle valve to cut off the path of the flammable refrigerant flowing from the outdoor side to the indoor side. Then, the compressor, the inner fan and the outer fan are turned off after running for a preset time length, so as to gradually transfer the flammable refrigerant from the indoor side to the outdoor side through the refrigerant pipeline. Thus, the embodiment of the present disclosure can discharge the flammable refrigerant stored in the indoor unit of the smart air conditioner to the outdoor side in advance when there is a safety hazard in the indoor, so as to assist the smart air conditioner to avoid secondary damage before the indoor hazard expands, which is beneficial to protect the user's home safety. In addition, when the smart air conditioner receives a release instruction of the safety linkage mode, it is judged that the indoor hazard has been released at this time. The smart air conditioner starts the power supply and controls the throttle valve to perform the opening valve action until it is fully opened, so as to make the flammable refrigerant flow back to the indoor side. Then, the smart air conditioner detects the current working current and judges whether the actual running state is normal according to the current working current, and then controls the smart air conditioner to complete the determination of the refrigerant leakage state before resetting the operation. When it is determined that no refrigerant leakage occurs, the smart air conditioner releases the safety linkage mode, so as to respond to the user's instruction to perform refrigeration, air supply or standby operation, so as to protect the user's experience. When it is determined that refrigerant leakage occurs, the smart air conditioner maintains the safety linkage mode and does not respond to the user's control instruction, so as to avoid the continuous leakage of flammable refrigerant from causing indoor hazards again, which is beneficial to protect the user's home safety.

[0077] Optionally, the processor determines the refrigerant leakage state of the smart air conditioner according to the current working current, including: the processor determines the current running frequency of the compressor and determines the preset check current corresponding to the current running frequency; in the case that the current working current is greater than or equal to the preset check current, the processor determines that the refrigerant leakage state is that no refrigerant leakage occurs; or, in the case that the current working current is less than the preset check current, the processor determines that the refrigerant leakage state is that refrigerant leakage occurs. In this way, the embodiments of the present disclosure can determine the corresponding preset check current in combination with the current running frequency of the compressor, so as to assist in determining the refrigerant leakage state. If the current working current is greater than or equal to the preset check current, it indicates that the actual running state of the smart air conditioner at this time is relatively normal, and it does not have the problem of too low working current caused by abnormal load. Therefore, the smart air conditioner determines that no refrigerant leakage phenomenon occurs at this time. If the current working current is less than the preset check current, the working current of the smart air conditioner at this time is too low, which is most likely caused by the abnormal load due to too little refrigerant circulation. Therefore, the smart air conditioner determines that refrigerant leakage occurs at this time.

[0078] Optionally, the processor determines the preset check current corresponding to the current running frequency, including: the processor determines the rated working current corresponding to the smart air conditioner according to the current running frequency; and the processor calculates the product of the rated working current and the check coefficient to obtain the preset check current. In this way, the embodiments of the present disclosure can determine the rated working current of the smart air conditioner when it is normally running at the current running frequency, and multiply the check coefficient based thereon, so as to obtain the corresponding preset check current, so as to reasonably judge whether the actual running state of the smart air conditioner is normal, which is conducive to indirectly completing the determination of the refrigerant leakage state.

[0079] Optionally, the check coefficient is less than 1. Preferably, the check coefficient can be set to 0.6. The check coefficient can also be adjusted according to the duration of the safety linkage mode, so as to fully consider the difficulty of the reset running of the smart air conditioner, and can also be set to 0.5 or 0.8 or other any reasonable numerical value.

[0080] Optionally, in the case that the refrigerant leakage state is that refrigerant leakage occurs, the processor controls the smart air conditioner to maintain the safety linkage mode, and further includes: the processor sends an alarm information to prompt that the smart air conditioner has refrigerant leakage. In this way, if the smart air conditioner identifies the refrigerant leakage phenomenon before the reset running, the embodiments of the present disclosure can remind the user by sending the alarm information while maintaining the safety linkage mode, so as to assist the user to eliminate the fault in time, which is conducive to improving the safety of the smart air conditioner.

[0081] Specifically, in some embodiments, the processor judges that the indoor danger has been eliminated at this time in response to the elimination instruction of the safety linkage mode. The intelligent air conditioner starts the power supply to start the working power supply, and controls the throttle valve to perform the valve opening action at a speed of 5 steps / s until the throttle valve is fully opened, so as to gradually flow the combustible refrigerant stored on the outdoor side back to the indoor side, to facilitate the reset operation of the intelligent air conditioner. At the same time, the processor controls the indoor fan to operate at a low wind resistance, and controls the outdoor fan to operate at a high wind resistance, and then controls the compressor to increase the frequency to a first operating frequency of 40 Hz at a speed of 0.5 Hz / s, and keeps operating. The first operating frequency of 40 Hz corresponds to a rated working current of 2.6 A in the normal mode of the intelligent air conditioner, and a check coefficient of 0.6 is introduced, and the processor determines that the preset check current corresponding to the first operating frequency of 40 Hz is 1.56 A. Then the processor detects the current working current of the intelligent air conditioner, and compares it with the preset check current 1.56 A, so as to complete the judgment of the refrigerant leakage state before the reset operation of the intelligent air conditioner, and further improve the safety of the reset operation. If the current working current is less than the preset check current 1.56 A, the working current is too low at this time, and it is extremely possible that the load is not normal due to too little refrigerant circulation, so the processor can judge that the intelligent air conditioner has a refrigerant leakage phenomenon at this time. In order to avoid possible system misjudgment, the processor can increase the refrigerant leakage judgment process again, and controls the compressor to increase the frequency to a second operating frequency of 50 Hz at a speed of 0.5 Hz / s, and then keeps operating. The second operating frequency of 50 Hz corresponds to a rated working current of 4.2 A, and a check coefficient of 0.6 is multiplied, and the processor determines that the preset check current corresponding to the second operating frequency of 50 Hz is 2.52 A. At this time, the processor updates the current working current of the intelligent air conditioner, and then compares it with the new preset check current 2.52 A, so as to further improve the reliability of the judgment of the refrigerant leakage phenomenon. If the updated current working current is greater than or equal to the new preset check current 2.52 A, it indicates that the actual operating state of the intelligent air conditioner at this time is relatively normal, and it does not have the problem of too low working current caused by abnormal load, so the processor judges that the intelligent air conditioner has not occurred refrigerant leakage phenomenon at this time. Then control the intelligent air conditioner to eliminate the safety linkage mode, so that it can respond to the user's instruction to perform refrigeration, air supply or standby operation, to protect the user's experience. If the updated current working current is still less than the new preset check current 2.52 A, the working current is too low at this time, and it is extremely possible that the load is not normal due to too little refrigerant circulation, so the processor judges that the intelligent air conditioner has a refrigerant leakage phenomenon at this time. Therefore, the processor controls the intelligent air conditioner to maintain the safety linkage mode, so that it does not respond to the user's control instruction, so as to avoid the continuous leakage of the combustible refrigerant from causing indoor danger again, which is beneficial to protect the user's home safety. At the same time, the processor sends alarm information prompting the refrigerant leakage to the terminal device of the user, to remind the user to eliminate the fault in time, which is beneficial to improve the safety of the intelligent air conditioner.
