In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0040] Unless otherwise stated, the term "plurality" means two or more.

[0042] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0043] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0044] In some embodiments, in combination Figure 1 As shown, an air conditioner 100 is provided, the air conditioner includes a compressor, a four-way reversing valve, an outdoor heat exchanger, an electronic expansion valve and an indoor heat exchanger which are sequentially connected to form a refrigerant flow path. The air conditioner also includes an air conditioner indoor unit and an air conditioner outdoor unit, wherein the outdoor heat exchanger is arranged at the air conditioner outdoor unit, and the indoor heat exchanger is arranged at the air conditioner indoor unit. The air conditioner indoor unit also includes a fan, which is used to blow the gas after heat exchange with the indoor heat exchanger into the room to adjust the indoor ambient temperature.

[0045] When the air conditioner is in cooling mode, the indoor heat exchanger is the evaporator and the outdoor heat exchanger is the condenser. When the air conditioner is in heating mode, the indoor heat exchanger is the condenser and the outdoor heat exchanger is the evaporator.

[0046] When the air is running in the self-cleaning mode, the cooling mode is run first, the indoor heat exchanger is the evaporator, and the outdoor heat exchanger is the condenser, so that frost forms on the surface of the indoor heat exchanger. After the frosting is completed, the heating mode is run again, the indoor heat exchanger is the condenser, and the outdoor heat exchanger is the evaporator, so as to defrost the indoor heat exchanger, and clean the indoor heat exchanger with the defrosting water. Specifically, in the process of running the self-cleaning mode, in the heating mode, the speed of the fan is controlled to be reduced, so that the coil temperature of the indoor heat exchanger is increased, thereby increasing the temperature of the gas that exchanges heat with the indoor heat exchanger, and using the obtained high-temperature gas to sterilize the inside of the air conditioner indoor unit, so as to enhance the sterilization effect of the air conditioner indoor unit, thereby enhancing the self-cleaning effect.

[0047] In some embodiments, an air conditioner is provided, comprising a processor and a memory storing program instructions, wherein the processor is configured to execute a control method for self-cleaning of the air conditioner when running the program instructions.

[0048] Combination Figure 1 The air conditioner shown, in some embodiments, is combined with Figure 2 As shown, a control method for air conditioner self-cleaning is provided, comprising:

[0049] S201, the processor controls the air conditioner to operate in a heating mode and controls the fan to rotate in a first direction in response to a self-cleaning request.

[0050] S202: The processor obtains operating parameters of the air conditioner.

[0051] S203: When the operating parameters meet the preset conditions, the processor controls the fan to rotate in the second direction.

[0052] The first direction is opposite to the second direction.

[0053] In this embodiment, the self-cleaning mode of the air conditioner is entered by responding to the self-cleaning request. Specifically, the air conditioner is controlled to operate in the heating mode, and the indoor heat exchanger functions as a condenser. The air conditioner heats the room, so that the coil temperature of the condenser increases, and then the bacteria on the indoor heat exchanger are sterilized by the high temperature. In addition, by controlling the fan to rotate in the first direction, the high-temperature air after the heat exchange with the indoor heat exchanger is blown to the space between the indoor heat exchanger and the air outlet, so as to remove the bacteria and dust in the space between the indoor heat exchanger and the air outlet.

[0054] Furthermore, by obtaining the operating parameters of the air conditioner, the operating state of the air conditioner heating mode is confirmed, and then the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air outlet is confirmed. When the operating parameters meet the preset conditions, the fan is controlled to rotate in the second direction. The high-temperature air after heat exchange with the indoor heat exchanger is blown to the space between the indoor heat exchanger and the air inlet, thereby removing bacteria and dust in the space between the indoor heat exchanger and the air inlet.

[0055] In some embodiments, the operating parameters include the operating time of the fan, and the step of obtaining the operating parameters of the air conditioner includes: obtaining a first operating time of the fan rotating along a first direction.

[0056] In this embodiment, the first operation time of the fan rotating in the first direction is obtained to determine the heating mode of the air conditioner, and the operation time of the fan rotating in the first direction, and then confirm the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air outlet, improve the control accuracy of self-cleaning, and improve the degree of cleaning of dust and bacteria in the air conditioner.

[0057] Specifically, when the first operation time meets the preset conditions, it is confirmed that the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air outlet meets the requirements. Dust and bacteria in other locations in the air conditioner can be removed to further improve the cleanliness of the air conditioner self-cleaning.

[0058] When the first operation time does not meet the preset condition, it is confirmed that the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air outlet does not meet the requirement. It is necessary to continue to control the fan to rotate in the first direction to continue to remove bacteria and dust in the space between the indoor heat exchanger and the air outlet, thereby improving the cleaning degree of the air conditioner self-cleaning.

[0059] Optionally, when the operating parameters meet preset conditions, the step of controlling the fan to rotate in the second direction includes: when the first operating time is greater than or equal to a first time threshold, controlling the fan to rotate in the second direction.

[0060] In this embodiment, after the fan runs for the first time threshold, the degree of bacteria and dust removal in the space between the indoor heat exchanger and the air outlet meets the requirements, so it only needs to run for the first time threshold. In addition, setting the first time threshold can prevent the first running time from being too long, causing the temperature inside the air conditioner to be too high, resulting in damage to the air conditioner.

[0061] Optionally, the value range of the first duration threshold includes 40 minutes to 50 minutes. The specific value of the first duration threshold includes: 40 minutes, 45 minutes or 50 minutes.

[0062] In some embodiments, in combination Figure 3 As shown, the embodiment of the present disclosure provides another control method for air conditioner self-cleaning, comprising:

[0063] S301, the processor controls the air conditioner to operate in a heating mode and controls the fan to rotate in a first direction in response to a self-cleaning request.

[0064] S302: The processor obtains a first operating time during which the fan rotates in a first direction.

[0065] S303: When the first operating time is greater than or equal to the first time threshold, the processor controls the fan to rotate in a second direction.

[0066] The first direction is opposite to the second direction.

[0067] In this embodiment, the self-cleaning mode of the air conditioner is entered by responding to the self-cleaning request. Specifically, the air conditioner is controlled to operate in the heating mode, and the indoor heat exchanger functions as a condenser. The air conditioner heats the room, so that the coil temperature of the condenser increases, and then the bacteria on the indoor heat exchanger are sterilized by the high temperature. In addition, by controlling the fan to rotate in the first direction, the high-temperature air after the heat exchange with the indoor heat exchanger is blown to the space between the indoor heat exchanger and the air outlet, so as to remove the bacteria and dust in the space between the indoor heat exchanger and the air outlet.

[0068] Furthermore, the first operating time of the fan rotating in the first direction is obtained to determine the heating mode of the air conditioner operation, and the operating time of the fan rotating in the first direction. Then, the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air outlet is confirmed. When the first operating time is greater than or equal to the first time threshold, the fan is controlled to rotate in the second direction. The high-temperature air after heat exchange with the indoor heat exchanger is blown to the space between the indoor heat exchanger and the air inlet, thereby removing bacteria and dust in the space between the indoor heat exchanger and the air inlet.

[0069] In some embodiments, the air conditioner includes an indoor heat exchanger, and the step of obtaining the operating parameters of the air conditioner includes: obtaining a first coil temperature of the indoor heat exchanger, and timing a first duration that the first coil temperature is greater than or equal to a first temperature threshold.

[0070] In this embodiment, the current coil temperature is confirmed by acquiring the first coil temperature of the indoor heat exchanger. When the current coil temperature is greater than or equal to the first temperature threshold, if this situation lasts for too long, the air conditioner may be damaged. Therefore, it is necessary to detect the duration of the current coil temperature being greater than or equal to the first temperature threshold to prevent damage to the air conditioner.

[0071] Optionally, the value range of the first temperature threshold includes 56° C. to 60° C. The specific value of the first temperature threshold includes: 56° C., 59° C. or 60° C.

[0072] In this embodiment, by setting the first temperature threshold, when the coil temperature is greater than or equal to the first temperature threshold, the sterilization effect in the air conditioner is better, so as to achieve high-temperature self-cleaning.

[0073] Optionally, when the operating parameters meet preset conditions, the step of controlling the fan to rotate in the second direction includes: when the first duration is greater than or equal to a second duration threshold, controlling the fan to rotate in the second direction.

[0074] In this embodiment, when the first duration is greater than or equal to the second duration threshold, it indicates that the first coil temperature has been greater than or equal to the first temperature threshold for a period of time. At this time, the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air outlet has reached the required level, and bacteria and dust in other locations in the air conditioner can be further removed to improve the cleanliness of the air conditioner. In addition, it can prevent the air conditioner from being damaged due to the excessively high temperature in the air conditioner for too long.

[0075] Optionally, the value range of the second duration threshold includes 30 minutes to 50 minutes. The specific value of the second duration threshold includes: 30 minutes, 40 minutes or 50 minutes.

[0076] Optionally, the value of the first temperature threshold is negatively correlated with the value of the second time threshold.

[0077] For example, when the first temperature threshold is 56°C, the second time threshold is 50 minutes. When the first temperature threshold is 59°C, the second time threshold is 40 minutes. When the first temperature threshold is 60°C, the second time threshold is 30 minutes.

[0078] In some embodiments, in combination Figure 4 As shown, the embodiment of the present disclosure provides another control method for air conditioner self-cleaning, comprising:

[0079] S401, the processor controls the air conditioner to operate in a heating mode and controls the fan to rotate in a first direction in response to a self-cleaning request.

[0080] S402: The processor obtains a first coil temperature of an indoor heat exchanger.

[0081] S403: The processor measures a first duration during which the temperature of the first coil is greater than or equal to a first temperature threshold.

[0082] S404: When the first duration is greater than or equal to a second duration threshold, the processor controls the fan to rotate in a second direction.

[0083] In this embodiment, the first coil temperature of the indoor heat exchanger is obtained, and the duration of the first coil temperature being greater than or equal to the first temperature threshold is timed. When the first duration is greater than or equal to the second duration threshold, it indicates that the first coil temperature is greater than or equal to the first temperature threshold for a period of time. At this point, the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air outlet has met the requirements, and bacteria and dust in other locations in the air conditioner can be further removed. In addition, it can prevent the problem of damage to the air conditioner caused by the excessively high temperature in the air conditioner for too long.

[0084] Furthermore, the fan is controlled to rotate in the second direction so that the high-temperature air after heat exchange with the indoor heat exchanger is blown to the space between the indoor heat exchanger and the air inlet, thereby removing bacteria and dust in the space between the indoor heat exchanger and the air inlet.

[0085] In some embodiments, in combination Figure 5 As shown, the embodiment of the present disclosure provides another control method for air conditioner self-cleaning, comprising:

[0086] S501, the processor controls the air conditioner to operate in a heating mode and controls the fan to rotate in a first direction in response to a self-cleaning request.

[0087] S502: The processor obtains operating parameters of the air conditioner.

[0088] S503: When the operating parameters meet the preset conditions, the processor controls the fan to rotate in the second direction.

[0089] S504: The processor obtains a second operating time duration during which the fan rotates in a second direction.

[0090] S505: When the second operating time is greater than or equal to a third time threshold, the processor exits the self-cleaning mode.

[0091] The first direction is opposite to the second direction.

[0092] In this embodiment, after controlling the fan to rotate in the second direction, the second operating time of the fan rotating in the second direction is obtained to confirm the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air inlet. When the second operating time is greater than or equal to the third time threshold, it indicates that the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air inlet has met the requirements, and then the self-cleaning mode is exited. At the same time, when the second operating time is greater than or equal to the third time threshold, the problem of excessive internal temperature of the air conditioner causing damage to the air conditioner may occur. In this way, while achieving precise control of the cleaning degree of self-cleaning, it also prevents the air conditioner from being damaged by running in the heating mode for too long.

[0093] Optionally, the value range of the third duration threshold includes 40 minutes to 50 minutes. The specific value of the third duration threshold includes: 40 minutes, 45 minutes or 50 minutes.

[0094] Optionally, the sum of the first duration threshold and the third duration threshold is less than or equal to 90 minutes.

[0095] In this embodiment, by setting the maximum value of the sum of the first duration threshold and the third duration threshold, the maximum operating time of the air conditioning heating mode is limited to prevent the air conditioning from running in the heating mode for too long, resulting in excessive temperature and causing damage to the air conditioner.

[0096] In some embodiments, in combination Figure 6 As shown, the embodiment of the present disclosure provides another control method for air conditioner self-cleaning, comprising:

[0097] S601, the processor controls the air conditioner to operate in a heating mode and controls the fan to rotate in a first direction in response to a self-cleaning request.

[0098] S602: The processor obtains operating parameters of the air conditioner.

[0099] S603: When the operating parameters meet the preset conditions, the processor controls the fan to rotate in the second direction.

[0100] S604: The processor obtains the temperature of the second coil of the indoor heat exchanger.

[0101] S605: The processor measures a second duration during which the temperature of the second coil is greater than or equal to a second temperature threshold.

[0102] S606: When the second duration is greater than or equal to a fourth duration threshold, the processor exits the self-cleaning mode.

[0103] The first direction is opposite to the second direction.

[0104] In this embodiment, by obtaining the second coil temperature of the indoor heat exchanger and timing the second duration that the second coil temperature is greater than or equal to the second temperature threshold, the duration of the excessively high coil temperature of the indoor heat exchanger is confirmed to prevent damage to the air conditioner due to excessively long duration of the high coil temperature.

[0105] Furthermore, when the second duration is greater than or equal to the fourth duration threshold, it indicates that the degree of removal of bacteria and dust in the space between the indoor heat exchanger and the air inlet has reached the required level, and the self-cleaning mode is then exited. While achieving precise control of the degree of self-cleaning, it also prevents the air conditioner from being damaged by running in the heating mode for too long.

[0106] Optionally, the value range of the second temperature threshold includes 56° C. to 60° C. The specific value of the second temperature threshold includes: 56° C., 59° C. or 60° C.

[0107] In this embodiment, by setting the second temperature threshold, when the coil temperature is greater than or equal to the second temperature threshold, the sterilization effect in the air conditioner is better, so as to achieve high-temperature self-cleaning.

[0108] Optionally, the value range of the fourth duration threshold includes 30 minutes to 50 minutes. The specific value of the fourth duration threshold includes: 30 minutes, 40 minutes or 50 minutes.

[0109] Optionally, the value of the second temperature threshold is negatively correlated with the value of the fourth duration threshold.

[0110] For example, when the second temperature threshold is 56°C, the fourth time threshold is 50 minutes. When the second temperature threshold is 59°C, the fourth time threshold is 40 minutes. When the second temperature threshold is 60°C, the fourth time threshold is 30 minutes.

[0111] Optionally, the sum of the second duration threshold and the fourth duration threshold is less than or equal to 90 minutes.

[0112] In this embodiment, by setting the maximum value of the sum of the second duration threshold and the fourth duration threshold, the maximum operating time of the air conditioning heating mode is limited to prevent the air conditioning from running in the heating mode for too long, resulting in excessive temperature and causing damage to the air conditioner.

[0113] Optionally, before exiting the self-cleaning mode, the step also includes: controlling the air conditioner to operate in cooling mode; obtaining the current indoor ambient temperature; when the current indoor ambient temperature is lower than a preset temperature, controlling the air guide plate to rotate to a preset angle, and controlling the fan to rotate in a first direction, and continuing for a preset time.

[0114] In this embodiment, the indoor heat exchanger is cooled by controlling the air conditioner to operate in cooling mode, so as to prevent the indoor heat exchanger from being damaged due to excessive temperature. In addition, when the indoor ambient temperature is lower than the preset temperature, the air guide plate is controlled to rotate at a preset angle to open the air outlet, and the fan is controlled to rotate in the first direction to discharge the residual heat in the air conditioner, and provide the user with a heating function, thereby improving the user experience.

[0115] Furthermore, when the air conditioner is in heating mode, the outdoor heat exchanger will frost when cooling. When the air conditioner is in cooling mode, the outdoor heat exchanger will defrost when heating. By first frosting the outdoor heat exchanger and then defrosting it, the outdoor heat exchanger can be cleaned by using defrosting water.

[0116] Optionally, the value range of the preset temperature includes: 18° C. to 22° C. The specific value of the preset temperature includes: 18° C., 20° C. or 22° C.

[0117] Optionally, the preset duration ranges from 30 seconds to 90 seconds. The specific values ​​of the preset duration include 30 seconds, 60 seconds or 90 seconds.

[0118] Optionally, after the step of exiting the self-cleaning mode, the method further includes: obtaining the operating state of the air conditioner before responding to the self-cleaning request, and controlling the air conditioner to restore the previous operating state.

[0119] In this embodiment, by obtaining the operating status of the air conditioner before responding to the self-cleaning request and controlling the air conditioner to restore the previous operating status, the user does not need to control the air conditioner again to start the operating status before self-cleaning, thereby reducing the operation steps and improving the user experience.

[0120] Specifically, if the operating state of the air conditioner before responding to the self-cleaning request is the cooling mode, after exiting the self-cleaning mode, the air conditioner resumes operating in the cooling mode. If the operating state of the air conditioner before responding to the self-cleaning request is the heating mode, after exiting the self-cleaning mode, the air conditioner resumes operating in the heating mode. If the operating state of the air conditioner before responding to the self-cleaning request is the standby mode, after exiting the self-cleaning mode, the air conditioner resumes operating in the standby mode.

[0121] In some embodiments, in combination Figure 7 As shown, the embodiment of the present disclosure provides another control method for air conditioner self-cleaning, comprising:

[0122] S701: The processor obtains the indoor ambient temperature in response to a self-cleaning request.

[0123] S702: When the indoor ambient temperature is less than or equal to a preset ambient temperature, the processor controls the air conditioner to operate in a cooling mode for a preset time.

[0124] S703, the processor controls the air conditioner to operate in a heating mode, and controls the fan to rotate in a first direction.

[0125] S704: The processor obtains operating parameters of the air conditioner.

[0126] S705: When the operating parameters meet the preset conditions, the processor controls the fan to rotate in the second direction.

[0127] The first direction is opposite to the second direction.

[0128] In this embodiment, after receiving the self-cleaning request, the indoor ambient temperature is obtained to confirm the self-cleaning mode adapted to the current environment. When the indoor ambient temperature is less than or equal to the preset ambient temperature, it means that the indoor ambient temperature is relatively low, and high-temperature self-cleaning can be performed, and then the air conditioner is controlled to run the cooling mode first, and then the heating mode, and the fan runs at the first speed. In this way, the condensed water generated by cooling first and then heating can be used to remove bacteria and dust from the indoor heat exchanger, thereby improving the cleaning degree of self-cleaning.

[0129] Furthermore, when the air conditioner is running in heating mode, the fan is controlled to start, so that air flows through the indoor heat exchanger, thereby increasing the drying speed of the surface of the indoor heat exchanger and preventing damage to the indoor heat exchanger.

[0130] When the indoor ambient temperature is greater than the preset ambient temperature, the current self-cleaning mode should be the normal self-cleaning mode.

[0131] When the indoor ambient temperature is higher than the preset ambient temperature, the indoor ambient temperature is relatively high, so normal self-cleaning is performed to reduce the temperature rise effect on the indoor ambient temperature. If the air conditioner performs self-cleaning at high temperature again, the temperature may rise quickly, causing the indoor ambient temperature to continue to rise, affecting the user experience. Therefore, during normal self-cleaning, the indoor heat exchanger is first controlled to run in cooling mode, and then the indoor heat exchanger is controlled to run in heating mode and the fan runs at the second speed.

[0132] The first rotation speed is smaller than the second rotation speed.

[0133] Specifically, when the outdoor unit is cooling, the speed of the indoor unit fan runs at the second speed, so that even if the indoor unit is heating, the coil temperature will not be too high due to heating.

[0134] In some embodiments, in combination Figure 8 As shown, the embodiment of the present disclosure provides another control method for air conditioner self-cleaning, comprising:

[0135] S801: The processor obtains the indoor ambient temperature in response to a self-cleaning request.

[0137] S803, the processor controls the air conditioner to operate in a heating mode, and controls the fan to rotate in a first direction.

[0138] S804: The processor obtains a first operating time during which the fan rotates in a first direction.

[0139] S805: When the first operating time is greater than or equal to the first time threshold, the processor controls the fan to rotate in the second direction.

[0140] S806: The processor obtains the temperature of the first coil of the indoor heat exchanger.

[0141] S807: The processor measures a first duration during which the temperature of the first coil is greater than or equal to a first temperature threshold.

[0142] S808: When the first duration is greater than or equal to a second duration threshold, the processor controls the fan to rotate in a second direction.

[0143] S809: The processor obtains a second operating time duration during which the fan rotates in a second direction.

[0144] S810: When the second operating time is greater than or equal to a third time threshold, the processor exits the self-cleaning mode.

[0145] S811: The processor obtains the temperature of the second coil of the indoor heat exchanger.

[0146] S812: The processor measures a second duration during which the temperature of the second coil is greater than or equal to a second temperature threshold.

[0147] S813: When the second duration is greater than or equal to a fourth duration threshold, the processor exits the self-cleaning mode.
