[0044] In addition, as Figure 1 indicated, the master control device 200 can include a CPU, a single-chip microcomputer or any hardware device capable of data processing and instruction sending embedded in the air conditioner, and the embodiment of the application is not limited specifically.

[0045] It should be noted that, Figure 1The scene schematic diagram of the air conditioner control system shown is only an example, and the air conditioner control method and scene described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a specific limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of the air conditioner control system and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0046] As shown in Figure 2 , Figure 2 A flowchart of an air conditioner control method provided by the present application, which can at least include the following steps S201-S203:

[0047] S201, in response to a cleaning instruction, controlling the air conditioner to operate in a cooling mode to make the indoor heat exchanger tube temperature of the air conditioner drop.

[0048] The cleaning instruction is used to represent that the air conditioner is controlled to enter a self-cleaning phase to clean the air conditioner. The cleaning instruction can be sent by a control device, which can be, for example, a remote controller, a control panel of the air conditioner, a terminal device, and the like. The terminal device can be a mobile phone, a tablet computer, a smart Bluetooth device, a notebook computer, a personal computer (PC), or the like.

[0049] Optionally, the cleaning instruction can be generated by the control device in response to a triggering operation of a user, or can be generated at a preset time interval. The preset time interval can be set according to a specific scenario, which is not specifically limited in the embodiments of the present application.

[0050] In the embodiments of the present application, when the main control device of the air conditioner receives the cleaning instruction sent by the control device, for example, the cleaning instruction for controlling the air conditioner to clean by the remote controller, the main control device controls the air conditioner to operate in the cooling mode to gradually drop the indoor heat exchanger tube temperature of the air conditioner.

[0051] S202, when the indoor heat exchanger tube temperature drops to the dew point temperature of the indoor heat exchanger, the fan of the outdoor unit of the air conditioner is controlled to reverse to clean the outdoor unit;

[0052] It can be understood that the dew point temperature refers to the temperature at which the water vapor in the air cools to saturation and begins to condense on a cold surface under a certain air pressure. When the humidity in the air increases, the dew point temperature also increases. When the air cools to equal to or lower than the dew point temperature, the water vapor begins to condense into water droplets or dew.

[0053] In the present embodiment, an indoor temperature sensor is pre-set to monitor the indoor heat exchanger tube temperature of the air conditioner.

[0054] Through the above step S201, it is known that the air conditioner runs in the cooling mode, and the indoor heat exchanger tube temperature gradually decreases. The main control device monitors the indoor heat exchanger tube temperature through the temperature sensor. When it is detected that the indoor heat exchanger tube temperature decreases to the dew point temperature, the indoor heat exchanger of the indoor unit starts to condense. At this time, the fan of the outdoor unit of the air conditioner is reversed. When the fan of the outdoor unit is reversed, the airflow in the outdoor heat exchanger is opposite to that when the fan of the outdoor unit is rotated in the normal direction, that is, the reverse airflow with a certain air pressure is generated, so that the dust and other foreign matters attached to the outdoor heat exchanger can be blown away. At this time, the reverse rotation of the fan does not affect the normal cleaning of the indoor unit, and the self-cleaning of the outdoor unit is realized while the cleaning of the indoor unit is performed.

[0055] It can be understood that the above-mentioned dew point temperature can be set according to specific scenes, which is not limited in the embodiments of the present application.

[0056] In some embodiments of the present application, the air conditioner control method provided by the present application further comprises:

[0057] If the indoor heat exchanger tube temperature decreases to the dew point temperature, the fan of the indoor unit is stopped.

[0058] From the above, when the indoor heat exchanger tube temperature decreases to the dew point temperature, the indoor heat exchanger of the indoor unit starts to condense. At this time, the fan of the indoor unit is gradually reduced to stop, which can avoid the airflow generated by the rotation of the indoor fan of the indoor heat exchanger from blowing away or evaporating the condensation formed on the indoor heat exchanger, improve the condensation effect of the indoor heat exchanger, and make the indoor heat exchanger form more condensation in the shortest possible time, thereby improving the cleaning effect and efficiency of the air conditioner.

[0059] S203, when the indoor heat exchanger tube temperature decreases to the frosting temperature of the indoor heat exchanger, and the indoor heat exchanger tube temperature continues to decrease below the frosting temperature for a first preset time, the air conditioner is controlled to run in the heating mode.

[0060] It can be understood that the frosting temperature refers to the temperature at which the water vapor in the air starts to cool and frost under a certain air pressure. When the temperature of the air decreases below the frosting temperature, the water vapor directly changes from gas to solid, that is, ice crystals. The frosting temperature is usually lower than the dew point temperature.

[0061] After the above steps S201 and S202, the air conditioner still runs in the cooling mode, which causes the indoor heat exchanger tube temperature to continue to decrease. If the main control device monitors that the indoor heat exchanger tube temperature decreases to the frosting temperature through the temperature sensor, the condensation formed on the indoor heat exchanger starts to frost, and after the frosting continues for a first preset time, the air conditioner is controlled to run in the heating mode, so that the indoor heat exchanger of the indoor unit starts to defrost.

[0062] The first preset time can be set according to a specific scene, for example, according to the indoor heat exchanger tube temperature.

[0063] In the embodiment, the stubborn stains on the indoor heat exchanger are cleaned through the frosting and defrosting process of the indoor heat exchanger, and the cleaning effect of the indoor unit is improved. In addition, the indoor heat exchanger is controlled to run in the heating mode after the indoor heat exchanger tube temperature drops to the frosting temperature and lasts for the first preset time, so that the condensation on the indoor heat exchanger is fully frosted, and the cleaning effect is improved.

[0064] It can be understood that the first preset time can be set according to a specific scene, for example, according to the indoor heat exchanger tube temperature, which is not limited in the embodiment.

[0065] Further, the air conditioner is controlled to run in the heating mode in step S203, which can be specifically: the air conditioner is controlled to run in the heating mode to raise the indoor heat exchanger tube temperature; and if the indoor heat exchanger tube temperature rises to the defrosting temperature, the air conditioner is controlled to maintain the indoor heat exchanger tube temperature in the preset frosting temperature range for a preset first defrosting time.

[0066] It can be understood that the preset first defrosting time can be set according to a specific scene, for example, according to the indoor heat exchanger tube temperature, which is not limited in the embodiment.

[0067] In the embodiment, the main control device controls the air conditioner to run in the heating mode, so that the indoor heat exchanger tube temperature rises to the defrosting temperature and lasts for a period of time, so that the frosting on the indoor heat exchanger is fully dissolved, and the cleaning effect is improved.

[0068] The air conditioner control method provided in the application receives the cleaning instruction, controls the air conditioner to run in the cooling mode first, so that the indoor heat exchanger tube temperature of the air conditioner drops, controls the outdoor unit fan of the air conditioner to reverse when the indoor heat exchanger tube temperature drops to the dew point temperature, so as to form an airflow opposite to the positive rotation of the fan in the indoor heat exchanger, that is, a reverse airflow with a certain air pressure, so as to blow away the dust and other stains of the outdoor unit, realize the cleaning of the outdoor unit, and then control the air conditioner to run in the heating mode after the indoor heat exchanger tube temperature drops to the frosting temperature and lasts for a first preset time, so as to defrost the indoor heat exchanger, thereby realizing the cleaning of the indoor unit. In the embodiment, the outdoor unit fan is controlled to reverse when the indoor heat exchanger tube temperature drops to the dew point temperature, that is, when the indoor heat exchanger starts to condense, at this time, the cleaning of the indoor unit is not affected, and the cleaning of the outdoor unit is realized, the cleaning efficiency of the air conditioner is improved, and the power consumption of the self-cleaning of the air conditioner is reduced, that is, the synchronous cleaning of the indoor unit and the outdoor unit of the air conditioner is realized with low power consumption.

[0069] After step S203, the air conditioner control method provided in the embodiments of the present application further includes the following steps:

[0070] 1. If the outdoor environment temperature of the air conditioner is less than or equal to the preset cleaning temperature, the air conditioner is controlled to continue operating in the heating mode, so as to reduce the outdoor heat exchanger temperature of the outdoor unit;

[0071] 2. If the outdoor heat exchanger temperature drops to the frost formation temperature and continues for a second preset time, the air conditioner is controlled to operate in the cooling mode, so as to defrost the outdoor heat exchanger of the outdoor unit.

[0072] The preset cleaning temperature can be set according to specific scenarios, which is not specifically limited in the embodiments of the present application.

[0073] The outdoor temperature sensor can be set in advance, and the outdoor environment temperature of the air conditioner is obtained by the master control device through the outdoor temperature sensor.

[0074] In the embodiments, after step S203, the master control device continues to operate the air conditioner in the heating mode, so that the outdoor heat exchanger temperature of the outdoor unit gradually decreases. When the outdoor heat exchanger temperature drops to the dew point temperature, the outdoor heat exchanger starts to condense. At this time, if the outdoor environment temperature is less than or equal to the preset cleaning temperature, the fan of the outdoor unit is stopped to avoid the airflow generated by the outdoor fan affecting the condensation effect. Then, after the master control device detects that the outdoor heat exchanger temperature drops to the frost formation temperature, the outdoor heat exchanger starts to frost. At this time, the master control device controls the air conditioner to operate in the cooling mode, so as to increase the outdoor heat exchanger temperature of the outdoor unit, thereby defrosting the outdoor heat exchanger of the outdoor unit to clean the stubborn stains on the outdoor heat exchanger, and achieving deep cleaning of the outdoor unit.

[0075] It can be understood that if the outdoor environment temperature is high, the outdoor unit cannot frost or the frost formation effect is poor. At this time, if the air conditioner is required to operate in the high-speed high-frequency heating mode to achieve frost formation, the power consumption is increased. Therefore, in the embodiments of the present application, it is required to determine whether the outdoor environment temperature is less than or equal to the preset cleaning temperature, and then determine whether to perform deep cleaning on the outdoor unit, so as to avoid the problem of poor cleaning effect in the case of high power consumption.

[0076] Further, if the outdoor environment temperature of the air conditioner is less than or equal to the preset cleaning temperature, the fan of the outdoor unit can be controlled to stop running, so as to improve the condensation and frost formation effect of the outdoor unit.

[0077] Further, after the air conditioner is controlled to operate in the cooling mode if the outdoor heat exchanger temperature drops to the frost formation temperature and continues for a second preset time, the air conditioner control method provided in the embodiments of the present application can further include: controlling the fan of the outdoor unit of the air conditioner to increase the speed.

[0078] In the embodiment, the increasing of the wind speed of the outdoor unit can increase the air pressure of the airflow formed by the reverse rotation of the fan in the outdoor heat exchanger, and the airflow with large air pressure can blow away stubborn dirt on the outdoor unit, thereby further improving the cleaning effect of the outdoor air conditioner.

[0079] In some embodiments of the present application, after the outdoor unit temperature drops to the frosting temperature and continues for a second preset time, the air conditioner control method provided by the present application can further include: controlling the compressor to stop and controlling the fan of the outdoor unit to rotate forward to automatically exit the overall cleaning mode after the air conditioner is controlled to operate in the cooling mode.

[0080] Further, if the initial outdoor environment temperature of the air conditioner is less than or equal to the preset cleaning temperature, the air conditioner is controlled, including:

[0081] If the outdoor environment temperature is less than or equal to the preset cleaning temperature, a prompt information is generated and sent to the client;

[0082] According to the confirmation cleaning information fed back by the client based on the prompt information, the air conditioner is controlled.

[0083] The prompt information is used to prompt the air conditioner to enter the overall cleaning mode.

[0084] The overall cleaning mode is used to represent deep cleaning of the outdoor unit, that is, deep cleaning of the entire air conditioner, which takes a long time.

[0085] The client can be a terminal device, a control panel, etc. The client can generate the confirmation cleaning information in response to the confirmation operation of the prompt information. The confirmation cleaning information is used to indicate that the user confirms that the air conditioner enters the overall cleaning mode, that is, deep cleaning of the outdoor unit.

[0086] Since deep cleaning of the outdoor unit takes a long time and consumes a lot of power, when the main control module detects that the outdoor environment temperature is less than or equal to the preset cleaning temperature, the prompt information is generated and sent to the client, so that the user confirms whether deep cleaning is needed, and after receiving the confirmation cleaning information fed back by the client based on the prompt information, the fan of the outdoor unit of the air conditioner is gradually reduced in speed until it stops running, thereby improving the user experience.

[0087] After step S203, the air conditioner control method provided by the present application can further include the following steps:

[0088] If the initial outdoor environment temperature of the air conditioner is greater than the preset cleaning temperature, the fan of the outdoor unit is controlled to rotate forward and the compressor is controlled to stop.

[0089] In the embodiment of the present application, if the initial outdoor environment temperature of the air conditioner is greater than the preset cleaning temperature, it indicates that it is not suitable to perform deep cleaning of the outdoor unit at this time, at this time, the fan of the outdoor unit is controlled to rotate forward and the compressor is stopped, that is, the normal cleaning mode is completed, and the cleaning mode is automatically exited.

[0090] After step S203, the air conditioner control method provided by the present application can further include a sterilization stage, as shown in the following steps:

[0091] If the inner tube temperature of the indoor heat exchanger rises to the sterilization temperature, the sterilization stage is entered and the third preset time is continuously run.

[0092] The temperature sensing bag or temperature sensor is set in advance to monitor the inner tube temperature of the indoor heat exchanger of the indoor unit.

[0093] The above-mentioned sterilization temperature can be set according to specific scenarios, which is not limited in the embodiment of the present application.

[0094] The above-mentioned third preset time can mean that the inner tube temperature of the air conditioner is controlled to be maintained within the preset sterilization temperature range within the third preset time, so as to achieve continuous sterilization of the indoor unit.

[0095] In the embodiment, after the main control device monitors that the inner tube temperature of the indoor heat exchanger rises to the sterilization temperature, the sterilization stage is entered to sterilize the indoor unit, and the third running time is continuously run, so as to further improve the cleaning effect of the air conditioner.

[0096] In some embodiments of the present application, after step S203, the indoor unit can be sterilized first, and then the outdoor unit is deeply cleaned, as shown in the following steps:

[0097] 1. If the inner tube temperature of the indoor heat exchanger rises to the sterilization temperature, the sterilization stage is entered and the third preset time is continuously run;

[0098] 2. If the outdoor environment temperature of the air conditioner is less than or equal to the preset cleaning temperature, the air conditioner is controlled to continue to run in the heating mode, so that the outer tube temperature of the outdoor heat exchanger of the outdoor unit decreases;

[0099] 3. If the outer tube temperature decreases to the frost temperature and continuously runs for the second preset time, the air conditioner is controlled to run in the cooling mode, so that the outdoor heat exchanger of the outdoor unit defrosts.

[0100] It can be understood that sterilization of the indoor unit requires the inner tube temperature of the indoor heat exchanger to be increased, so the air conditioner runs in the heating mode, at this time the outer tube temperature of the outdoor heat exchanger continuously decreases. Therefore, in the embodiment, the deep cleaning of the outdoor unit is performed after the sterilization of the indoor unit is completed, which can reduce power consumption and does not need to heat from the indoor unit again, so that the outer tube temperature of the outdoor heat exchanger rapidly decreases.

[0101] From the above embodiments, the air conditioner control method provided by the application provides two air conditioner cleaning modes: a regular cleaning mode and a comprehensive cleaning mode. Moreover, the selection of the air conditioner cleaning mode needs to be determined according to the outdoor environment temperature and the user selection, so in the embodiments of the application, the outdoor environment temperature can also be obtained in direct response to the cleaning instruction, and the corresponding air conditioner cleaning mode is determined according to the outdoor environment temperature and the user selection to clean the air conditioner accordingly, such as Figure 3 As shown, the following steps can be specifically implemented:
