This means that when the ambient temperature is low, it takes a long time for the indoor temperature to reach the user's set temperature, and the heating efficiency cannot meet the user's needs, resulting in a poor user experience. Furthermore, if the ambient temperature is too low and the user cannot start the air conditioner in time, indoor items are easily frozen and damaged, causing property loss.

[0010] In one technical solution of the above-mentioned air conditioner control method, the step of selectively controlling the air conditioner's heating mode to operate with parameters corresponding to the magnitude relationship between the current ambient temperature data obtained in step S4 and the user-set antifreeze temperature or electric heating start temperature, and turning the electric heating device on or off, includes: if the data source of the current ambient temperature data obtained in step S4 is an outdoor ambient temperature data source, based on the magnitude relationship between the current ambient temperature data obtained in step S4 and the user-set antifreeze temperature, selectively controlling the air conditioner to execute the heating mode with corresponding preset parameters and turning on the air conditioner's electric heating; if the data source of the current ambient temperature data obtained in step S4 is an indoor ambient temperature data source, based on the magnitude relationship between the current ambient temperature data obtained in step S4 and the user-set electric heating start temperature, selectively controlling the air conditioner to execute the heating mode with corresponding preset parameters and turning off the air conditioner's electric heating; or, continuing to selectively control the air conditioner to execute the heating mode with corresponding preset parameters and turn on the air conditioner's electric heating based on the magnitude relationship between the current ambient temperature data obtained in step S4 and the user-set antifreeze temperature.

[0011] In one technical solution of the above-mentioned air conditioner control method, the step of selectively controlling the air conditioner to turn on or off and selectively controlling the air conditioner to execute the heating mode with preset anti-freeze parameters based on the relationship between the current ambient temperature data obtained in step S4 and the anti-freeze temperature set by the user includes: determining whether the current ambient temperature data obtained in step S4 is lower than the anti-freeze temperature set by the user; if the current ambient temperature data obtained in step S4 is lower than the anti-freeze temperature set by the user, then the air conditioner is turned on and controlled to execute the heating mode with preset anti-freeze parameters or the air conditioner's heating mode is kept running with preset anti-freeze parameters, so that the air conditioner is in the on state and the air conditioner's heating mode is running with preset anti-freeze parameters; if the determination is not correct, then the air conditioner is kept in the off state or the air conditioner is turned off, so that the air conditioner is in the off state.

[0012] In a second aspect, a control device is provided, comprising a processor and a memory, the memory being adapted to store a plurality of program codes, the program codes being adapted to be loaded and executed by the processor to perform the control method of the air conditioner described in any of the above-described technical solutions.

[0015] The above-described one or more technical solutions of the present invention have at least one or more of the following beneficial effects: By installing an auxiliary electric heating device inside the air conditioner, when the indoor unit of the air conditioner is in heating mode, based on the obtained current state of the air conditioner, the current ambient temperature data, and the relationship between the user-set antifreeze temperature and the electric heating start temperature, the air conditioner is selectively controlled to turn on or off, the electric heating device is turned on or off, and the heating mode is selectively controlled to operate with parameters corresponding to the relationship. This achieves selective control of the air conditioner based on the obtained current state of the air conditioner, the current ambient temperature data, and the relationship between the user-set antifreeze temperature and the electric heating start temperature when the indoor unit is in heating mode. Furthermore, it achieves selective control of the air conditioner based on the relationship between the current ambient temperature data and the two user-set temperatures when the air conditioner is turned off, thus avoiding the problem in the prior art where indoor items are easily frozen and damaged due to low ambient temperature and the user's inability to start the air conditioner in time, resulting in property damage.

[0016] Furthermore, in implementing the technical solution of the present invention, when the air conditioner is currently in the "on" state, the corresponding heating mode is executed based on the relationship between the current ambient temperature data, the electric heating start-up temperature, and the antifreeze temperature, and the electric heating of the air conditioner is selectively turned on or off. Specifically, when the current ambient temperature data is lower than the antifreeze temperature, the air conditioner is controlled to execute the heating mode with the first preset parameters and turn on the electric heating. The first preset parameters include the maximum fan speed, which enables rapid heating of the indoor temperature. When the current ambient temperature data is higher than the electric heating start-up temperature, the air conditioner is controlled to execute the heating mode with the parameters set by the user and turn off the electric heating. This ensures heating while promptly turning off the electric heating, avoiding excessive energy consumption of the air conditioner.

[0017] Furthermore, in implementing the technical solution of the present invention, after a preset time period, if the current state of the air conditioner obtained in step S2 is off, and the current ambient temperature data obtained in step S4 is lower than the anti-freeze temperature, then the air conditioner is controlled to be turned on and the heating mode of the air conditioner is operated with preset anti-freeze parameters. This achieves timely activation of the air conditioner and execution of the heating mode with preset anti-freeze parameters when the ambient temperature is too low, thereby avoiding indoor freezing. When the current ambient temperature data obtained in step S4 is not lower than the anti-freeze temperature, the air conditioner is controlled to perform the corresponding operation and be turned off. This achieves timely shutdown of the air conditioner when the ambient temperature reaches the user-set anti-freeze temperature, ensuring anti-freeze while avoiding resource waste.

[0018] Furthermore, in implementing the technical solution of the present invention, after a preset time period, the current ambient temperature data is reacquired, and based on the current state of the air conditioner obtained in step S2 and the data source of the current ambient temperature data obtained in step S4, the current ambient temperature data obtained in step S4 is selectively compared with at least one of the user-set temperatures, and the air conditioner is selectively controlled to perform corresponding operations based on the size relationship. This achieves the periodic selective control of the air conditioner to perform corresponding adjustment operations based on the current ambient temperature data, reducing the amount of operation required by the user and thus improving the intelligent effect of the air conditioner.

[0028] See appendix Figure 1 , Figure 1 This is a schematic flowchart illustrating the main steps of a control method for an air conditioner according to an embodiment of the present invention. The air conditioner is equipped with an auxiliary electric heating device, such as… Figure 1 As shown, the control method of the air conditioner in this embodiment of the invention mainly includes the following steps S1-S3.

[0029] Step S1: Obtain the user-set antifreeze temperature and electric heating start temperature, wherein the user-set antifreeze temperature is lower than the user-set electric heating start temperature;

[0030] Specifically, in some embodiments, the electric heating start-up temperature can be any temperature value between 3.5°C and 18°C, and the antifreeze temperature can be any temperature value between -20°C and 3.5°C. The temperature settings of the electric heating start-up temperature and the antifreeze temperature mentioned here are only illustrative examples. In actual testing, those skilled in the art can set them according to actual needs, as long as the antifreeze temperature is lower than the electric heating start-up temperature. Further details are omitted here.

[0031] Step S2: Obtain the current status of the air conditioner, the current function mode of the indoor unit, and the current ambient temperature data. The current status includes whether the air conditioner is off or on, and the current function mode includes heating mode, cooling mode, or dehumidification mode.

[0032] Specifically, in some embodiments, obtaining the current ambient temperature data includes: obtaining the current temperature value of the environmental data source with the highest priority as the current ambient temperature data based on the priority of each environmental data source, wherein the environmental data source includes at least an outdoor environmental data source and an indoor environmental data source, and the priority of the outdoor environmental data source is higher than that of the indoor environmental data source.

[0033] Specifically, in some embodiments, the indoor unit of the air conditioner is equipped with an indoor ambient temperature sensor, and the outdoor ambient data source includes at least a receiving outdoor ambient data source and a collecting outdoor ambient data source. The air conditioner interacts with a weather server, and the outdoor unit of the air conditioner is also equipped with multiple outdoor ambient temperature sensors. Specifically, in some embodiments, the current temperature value of the receiving outdoor ambient data source is obtained by obtaining the current temperature information from the weather server, and / or, the current temperature value of the collecting outdoor ambient data source is obtained by obtaining the average of the current temperature values ​​of multiple outdoor ambient temperature sensors; wherein, the receiving outdoor ambient data source has a higher priority than the collecting outdoor ambient data source; the current temperature value of the indoor ambient temperature data source is obtained through the current temperature value of the indoor ambient temperature sensor, wherein, the collecting outdoor ambient data source has a higher priority than the indoor ambient data source.

[0034] Specifically, in some embodiments, obtaining the current temperature value of the highest-priority environmental data source as the current ambient temperature data based on the priority of each environmental data source includes: obtaining the current temperature value of the highest-priority environmental data source, i.e., receiving the outdoor environmental data source, and determining whether the acquisition was successful; if so, then using the current temperature value of the outdoor environmental data source as the current ambient temperature data; otherwise, obtaining the current temperature value of the outdoor environmental data source and determining whether the acquisition was successful; if so, then using the current temperature value of the outdoor environmental data source as the current ambient temperature data; otherwise, obtaining the current temperature value of the indoor environmental data source and using the current temperature value of the indoor environmental data source as the current ambient temperature data. Alternatively, obtaining the current temperature values ​​of each environmental data source, and selecting the current temperature value of the highest-priority environmental data source as the current ambient temperature data from among the environmental data sources for which current temperature values ​​have been obtained.

[0035] Step S3: When the current function mode of the indoor unit of the air conditioner is heating mode, based on the current state of the air conditioner and the relationship between the current ambient temperature data and the user-set antifreeze temperature and electric heating start temperature, selectively control the air conditioner to turn on or off, the electric heating device to turn on or off, and selectively control the heating mode to operate with parameters corresponding to the relationship.

[0036] Based on steps S1-S3 above, by installing an auxiliary electric heating device inside the air conditioner, when the indoor unit is in heating mode, the system selectively controls the air conditioner to turn on or off, the electric heating device to turn on or off, and the heating mode to operate with parameters corresponding to the aforementioned relationship, based on the current state of the air conditioner, the current ambient temperature data, and the relationship between the user-set antifreeze temperature and the electric heating start temperature. This achieves selective control of the air conditioner when it is in heating mode, based on the current state of the air conditioner, the current ambient temperature data, and the relationship between the user-set antifreeze temperature and the electric heating start temperature. Furthermore, it enables selective control of the air conditioner when it is turned off, based on the relationship between the current ambient temperature data and the two user-set temperatures. This avoids the problem in existing technologies where indoor items are easily frozen and damaged due to low ambient temperatures, preventing property loss if the user cannot start the air conditioner in time.

[0037] Specifically, in some embodiments, selectively controlling the air conditioner to turn on or off, the electric heating device to turn on or off, and selectively controlling the heating mode to operate with parameters corresponding to the magnitude relationship, based on the current state of the air conditioner and the relationship between the current ambient temperature data and the user-set anti-freeze temperature and electric heating start temperature, includes: if the current state of the air conditioner is off, determining whether the current ambient temperature data is lower than the user-set electric heating start temperature; if the determination is no, keeping the air conditioner off; if the determination is yes, determining whether the current ambient temperature data is lower than the user-set anti-freeze temperature; if the current ambient temperature data is lower than the user-set anti-freeze temperature, turning on the air conditioner and controlling the air conditioner to execute the heating mode with preset anti-freeze parameters, wherein the anti-freeze parameters include at least the minimum fan speed; if the determination is no, keeping the air conditioner off.

[0038] Specifically, in some embodiments, the step of selectively controlling the air conditioner to turn on or off, the electric heating device to turn on or off, and selectively controlling the heating mode to operate with parameters corresponding to the magnitude relationship based on the current state of the air conditioner and the relationship between the current ambient temperature data and the user-set antifreeze temperature and electric heating start temperature includes: if the current state of the air conditioner is on, then obtaining the heating parameters of the heating mode set by the user, and determining whether the current ambient temperature data is lower than the user-set electric heating start temperature; if the determination is no, then controlling the air conditioner to execute the heating mode with the user-set heating parameters and turning off the electric heating of the air conditioner; if the determination is yes, then determining whether the current ambient temperature data is lower than the user-set antifreeze temperature; if the current ambient temperature data is lower than the user-set antifreeze temperature, then controlling the air conditioner to execute the heating mode with a first preset parameter and turning on the electric heating of the air conditioner, wherein the first preset parameter includes at least the maximum fan speed; if the determination is no, then controlling the air conditioner to execute the heating mode with the user-set heating parameters and turning on the electric heating of the air conditioner.

[0039] Specifically, in some embodiments, the heating parameters of the user-set heating mode include at least the target heating temperature and the heating fan speed. The selection of heating parameters here is only an illustrative example. In actual testing, those skilled in the art can select according to actual needs, which will not be elaborated here.

[0040] In the above embodiments, when the air conditioner is currently powered on, the corresponding heating mode is executed based on the relationship between the current ambient temperature data, the electric heating start-up temperature, and the antifreeze temperature. The electric heating of the air conditioner is selectively turned on or off. Specifically, when the current ambient temperature is lower than the antifreeze temperature, the air conditioner is controlled to execute the heating mode with first preset parameters and turn on the electric heating. These first preset parameters include the maximum fan speed, enabling rapid heating of the indoor temperature. When the current ambient temperature is higher than the electric heating start-up temperature, the air conditioner is controlled to execute the heating mode with user-set parameters and turn off the electric heating. This ensures heating while promptly shutting off the electric heating, preventing excessive energy consumption of the air conditioner.

[0041] Furthermore, in some embodiments, if the air conditioner is currently powered on, and after controlling the air conditioner to execute the heating mode according to the user-set heating parameters based on the relationship between the current ambient temperature data, the user-set anti-freeze temperature, and the electric heating start-up temperature, and turning off the air conditioner's electric heating, the method further includes: after a preset auxiliary electric heating start-up time, obtaining the current indoor temperature value of the air conditioner; if the current indoor temperature value of the air conditioner has reached the target heating temperature, then turning off the air conditioner's electric heating; if the current indoor temperature value of the air conditioner has not reached the target heating temperature, then turning off the air conditioner's electric heating. Heating is turned on, and after a preset time, the current indoor temperature value of the air conditioner is retrieved again. Based on whether the current indoor temperature value of the air conditioner has reached the target heating temperature, the electric heating of the air conditioner is selectively turned on or off. If the current ambient temperature is lower than the user-set antifreeze temperature, the electric heating of the air conditioner is turned on and locked regardless of whether the current indoor temperature value of the air conditioner has reached the target heating temperature. The on state of the electric heating is unlocked when the current ambient temperature is equal to or higher than the user-set antifreeze temperature.

[0042] Specifically, in some embodiments, the preset auxiliary electric heating start-up time can be 30 minutes. The setting of the preset auxiliary electric heating start-up time here is only an illustrative example. In actual testing, those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0043] See appendix Figure 2 , Figure 2 This is a partial flowchart illustrating steps S4 to S5 of a control method for an air conditioner according to an embodiment of the present invention. Further, in some embodiments, such as... Figure 2As shown, after selectively controlling the air conditioner to turn on or off, the electric heating device to turn on or off, and selectively controlling the heating mode to operate with parameters corresponding to the magnitude relationship, the method further includes: after a preset time period, executing steps S4 and S5; wherein, step S4 includes: acquiring current ambient temperature data; step S5 includes: when the current state of the air conditioner acquired in step S2 is "on", selectively controlling the air conditioner's heating mode to operate with parameters corresponding to the magnitude relationship and turning the electric heating device on or off, based on the data source of the current ambient temperature data acquired in step S4 and the magnitude relationship between the current ambient temperature data acquired in step S4 and the user-set antifreeze temperature or electric heating start temperature; when the current state of the air conditioner acquired in step S2 is "off", selectively controlling the air conditioner to turn on or off and selectively controlling the air conditioner to execute the heating mode with preset antifreeze parameters, based on the magnitude relationship between the current ambient temperature data acquired in step S4 and the user-set antifreeze temperature.

[0044] Specifically, in some embodiments, the preset duration can be 5 minutes. The setting of the preset duration here is only an illustrative example. In actual testing, those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0045] Specifically, in some embodiments, the step of selectively controlling the air conditioner's heating mode to operate with parameters corresponding to the relationship between the current ambient temperature data obtained in step S4 and the user-set antifreeze temperature or electric heating start temperature, and turning the electric heating device on or off, includes: if the data source of the current ambient temperature data obtained in step S4 is an outdoor ambient temperature data source, selectively controlling the air conditioner to execute the heating mode with corresponding preset parameters and turning on the air conditioner's electric heating based on the relationship between the current ambient temperature data obtained in step S4 and the user-set antifreeze temperature; if the data source of the current ambient temperature data obtained in step S4 is an indoor ambient temperature data source, selectively controlling the air conditioner to execute the heating mode with corresponding preset parameters and turning off the air conditioner's electric heating based on the relationship between the current ambient temperature data obtained in step S4 and the user-set electric heating start temperature; or, continuing to selectively control the air conditioner to execute the heating mode with corresponding preset parameters and turn on the air conditioner's electric heating based on the relationship between the current ambient temperature data obtained in step S4 and the user-set antifreeze temperature.

[0046] In the above embodiment, by re-acquiring the current ambient temperature data after a preset time period, and by selectively comparing the current ambient temperature data obtained in step S4 with at least one of the user-set temperatures based on the current state of the air conditioner obtained in step S2 and the data source of the current ambient temperature data obtained in step S4, and selectively controlling the air conditioner to perform corresponding operations based on the size relationship, the system achieves periodic selective control of the air conditioner to perform corresponding adjustment operations based on the current ambient temperature data, reducing the amount of operation required by the user and thus improving the intelligence effect of the air conditioner.

[0047] Specifically, in some embodiments, the step of selectively controlling the air conditioner to turn on or off, and selectively controlling the air conditioner to execute the heating mode with preset anti-freeze parameters, based on the relationship between the current ambient temperature data obtained in step S4 and the anti-freeze temperature set by the user, includes: determining whether the current ambient temperature data obtained in step S4 is lower than the anti-freeze temperature set by the user; if the current ambient temperature data obtained in step S4 is lower than the anti-freeze temperature set by the user, then the air conditioner is turned on and controlled to execute the heating mode with preset anti-freeze parameters, or the air conditioner's heating mode is kept running with preset anti-freeze parameters, so that the air conditioner is in the on state and the air conditioner's heating mode is running with preset anti-freeze parameters; if the determination is not correct, then the air conditioner is kept in the off state or the air conditioner is turned off, so that the air conditioner is in the off state.

[0048] In the above embodiments, after a preset time period, if the current state of the air conditioner obtained in step S2 is off, and the current ambient temperature data obtained in step S4 is lower than the anti-freeze temperature, the air conditioner is controlled to be turned on and its heating mode is set to the preset anti-freeze parameters. This ensures that when the ambient temperature is too low, the air conditioner is turned on in time and the heating mode is executed with the preset anti-freeze parameters, thereby preventing the room from freezing. If the current ambient temperature data obtained in step S4 is not lower than the anti-freeze temperature, the air conditioner is controlled to perform the corresponding operation and be turned off. This ensures that when the ambient temperature reaches the user-set anti-freeze temperature, the air conditioner is turned off in time, ensuring anti-freeze protection while avoiding resource waste.

They can be executed simultaneously (in parallel) or in other orders, and these variations are all within the scope of protection of the present invention.
