[0032] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0033] In this embodiment of the disclosure, the terminal device refers to an electronic device with wireless connectivity. The terminal device can communicate with the aforementioned smart home appliances by connecting to the internet, or directly via Bluetooth, Wi-Fi, or other methods. In some embodiments, the terminal device may be, for example, a mobile device, a computer, or an in-vehicle device built into a hovercraft, or any combination thereof.

Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0034] Figure 1 This is a structural schematic diagram of an outdoor unit of an air conditioner provided in an embodiment of this disclosure; combined with Figure 1 As shown in the illustration, this disclosure provides an outdoor unit for an air conditioner, wherein a telescopic device is provided inside the air outlet of the outdoor unit. As an example, the telescopic device includes multiple telescopic members distributed at different positions inside the air outlet. Here, the shape and material of the multiple telescopic members are not specifically limited, as long as they can simultaneously extend from the inside of the air outlet and partially block the air outlet. As a preferred embodiment, when the telescopic device is extended in a controlled manner, the multiple telescopic members can extend from the inside of the air outlet in the direction of blocking the air outlet, and can be assembled into a ring to partially block the air outlet. It is understood that the larger the area of ​​the extended multiple telescopic members, the larger the area of ​​the air outlet blocked after the telescopic members are assembled into a ring, and the stronger the air pressure at the air outlet. The outdoor unit also includes a control device for controlling the extension and retraction of the telescopic device as needed. Under these conditions, after the air conditioner is running stably, the air conditioner control extension device can execute the initial air mass penetration strategy. This causes the extension device to extend from the inside of the air outlet of the outdoor unit towards the direction of blocking the air outlet until the area of ​​the air outlet of the outdoor unit is reduced to the first area. This facilitates increasing the air pressure at the outdoor unit's air outlet by reducing the air outlet area. The air pressure at the air outlet can then accurately and effectively penetrate the formed hot / cold air mass, further improving the heat exchange efficiency of the outdoor unit.

[0035] Figure 2 This is a schematic diagram of a method for controlling an outdoor unit of an air conditioner provided in an embodiment of this disclosure; combined with Figure 2As shown in the figure, this disclosure provides a method for controlling an outdoor unit of an air conditioner, including:

[0036] S21, the air conditioner obtains the outdoor ambient temperature and the operating frequency of the air conditioner compressor.

[0037] S22, the air conditioner determines the target operating frequency of the air conditioner compressor based on the outdoor ambient temperature.

[0038] S23, when the operating frequency reaches the target operating frequency and continues to operate for a first duration, the air conditioning control telescopic device executes the first air mass penetration strategy, so that the telescopic device is controlled to extend from the inside of the air outlet of the air conditioning outdoor unit towards the direction of blocking the air outlet until the air outlet area of ​​the air conditioning outdoor unit is reduced to the first area.

[0039] In this solution, the air conditioner can obtain the outdoor ambient temperature through various methods. In one example, the air conditioner can obtain the outdoor ambient temperature through an associated ambient temperature sensor. In another example, the air conditioner can obtain the current outdoor ambient temperature through weather forecast information from a mobile device. This allows for accurate acquisition of the outdoor ambient temperature. Furthermore, the air conditioner can also obtain its operating parameters to determine the operating frequency of the air conditioner compressor.

[0040] Furthermore, the air conditioner can determine the target operating frequency of its compressor by combining the outdoor ambient temperature. Specifically, the air conditioner determines the target operating frequency of its compressor based on the outdoor ambient temperature, including: obtaining the air conditioner's model information and its current operating mode information; and determining the target operating frequency of the compressor based on the air conditioner's model information, current operating mode information, and outdoor ambient temperature. The current operating mode information is either cooling mode or heating mode. In this way, the target operating frequency can be accurately determined by combining the air conditioner's model information, current operating mode information, and outdoor ambient temperature.

[0041] Furthermore, once the operating frequency reaches the target operating frequency and continues to operate for a first duration, confirming that the air conditioner is operating stably, the telescopic device can be controlled to execute the initial air mass breakthrough strategy. This involves controlling the telescopic device to extend from the inside of the air outlet of the outdoor unit towards the direction of obstructing the air outlet until the area of ​​the air outlet of the outdoor unit is reduced to the first area. As an example, the first duration is 60 minutes, and the initial air mass breakthrough strategy includes controlling the telescopic device to execute the first air mass breakthrough command. In this way, the first duration and the initial air mass breakthrough strategy can be accurately determined.

[0042] In an optimized solution, if it is determined that the air conditioner has been running stably and the duration of its status change exceeds the third duration, the air conditioner needs to re-record the duration for which its operating frequency reaches the target operating frequency and continues to run, in order to determine whether this duration has reached the first duration. Here, the third duration is 5 minutes. If the air conditioner is turned off or its mode is switched, it is determined that the air conditioner has experienced a status change. In this way, by combining the air conditioner's operating status, it is possible to accurately determine whether the operating frequency has reached the target operating frequency and whether it has continued to run for the first duration.

[0043] Optionally, the first area can be determined in the following ways;

[0044] The air conditioner obtains its model information; based on this model information, it determines the initial air outlet size; it calculates the initial area of ​​the air outlet; and it uses the product of a first proportionality coefficient and the initial area as the first area. The initial area is the standard area of ​​the air outlet for this model, and the first proportionality coefficient is 1 / 4. This method ensures accurate determination of the first area.

[0045] The method for controlling an outdoor air conditioner unit provided in this disclosure acquires the outdoor ambient temperature and the operating frequency of the air conditioner compressor. Based on the outdoor ambient temperature, a target operating frequency for the air conditioner compressor is determined. When the operating frequency reaches the target frequency and continues to operate for a first duration, the telescopic device is controlled to execute a first air mass breakthrough strategy. This causes the telescopic device to extend controlled from the inside of the air outlet of the outdoor air conditioner unit towards the direction of blocking the air outlet until the area of ​​the air outlet of the outdoor air conditioner unit is reduced to a first area. With this solution, even when a telescopic device is installed inside the air outlet of the outdoor air conditioner unit, after the air conditioner is running stably, the telescopic device can be controlled to execute a first air mass breakthrough strategy. This allows the telescopic device to extend controlled from the inside of the air outlet of the outdoor air conditioner unit towards the direction of blocking the air outlet, thereby increasing the air pressure at the outdoor unit's air outlet by reducing the air outlet area. This enables precise and effective breakthrough of the formed hot / cold air mass, further improving the heat exchange efficiency of the outdoor air conditioner unit.

[0046] Figure 3 This is a schematic diagram of a method for determining a target operating frequency provided in an embodiment of this disclosure; combined with Figure 3 As shown, optionally, in step S22, the air conditioner determines the target operating frequency of the air conditioner compressor based on the outdoor ambient temperature, including:

[0047] S31, the air conditioner obtains the model information and the current operating mode information of the air conditioner.

[0048] S32: The air conditioner determines the target operating frequency of the air conditioner compressor based on the air conditioner model information, the air conditioner's current operating mode information, and the outdoor ambient temperature.

[0049] In this solution, the air conditioner's model information can be obtained through its installation information, and its current operating mode information can be obtained through its operating parameter information. Specifically, the current operating mode information indicates whether it is cooling or heating mode. This method enables the accurate acquisition of both the air conditioner's model information and its current operating mode.

[0050] Furthermore, after obtaining the air conditioner's model information and current operating mode information, the air conditioner can determine the target operating frequency of the compressor by combining these information with the outdoor ambient temperature. As an example, the air conditioner can access an operating database that stores the correlation between different air conditioner model information, current operating mode information, outdoor ambient temperature, and stable compressor operating frequencies. The air conditioner can then match the stable compressor operating frequencies associated with the air conditioner's model information, current operating mode information, and outdoor ambient temperature in the operating database and determine these frequencies as the target operating frequency for the air conditioner compressor. In this way, the target operating frequency can be accurately determined by combining the air conditioner's model information, current operating mode information, and outdoor ambient temperature.

[0051] Optionally, S32, the air conditioner determines the target operating frequency of the air conditioner compressor based on the air conditioner model information, the air conditioner's current operating mode information, and the outdoor ambient temperature, including:

[0052] The air conditioner obtains an operating database, which stores information about different air conditioner models, the operating mode of the air conditioner, and the relationship between outdoor ambient temperature and the stable operating frequency of the compressor.

[0053] The air conditioner matches the model information, the current operating mode information, and the outdoor ambient temperature of the compressor in the operating database, and determines the stable operating frequency of the air conditioner compressor as the target operating frequency.

[0054] In this solution, the air conditioner can obtain the operating database stored on the server. The operating database stores information about different air conditioner models, the operating mode of the air conditioner, and the correlation between outdoor ambient temperature and the stable operating frequency of the compressor. As an example, the operating database includes the following: if the air conditioner model information is 1U12***FRA, the air conditioner is operating in cooling mode, and the outdoor ambient temperature is between 25℃ and 30℃, the associated compressor's stable operating frequency is 84Hz; if the air conditioner model information is 1U12***FRA, the air conditioner is operating in cooling mode, and the outdoor ambient temperature is between 30℃ and 35℃, the associated compressor's stable operating frequency is 92Hz; if the air conditioner model information is 1U12***FRA, the air conditioner is operating in heating mode, and the outdoor ambient temperature is between -5℃ and 0℃, the associated compressor's stable operating frequency is 99Hz; if the air conditioner model information is 1U12***FRA, the air conditioner is operating in heating mode, and the outdoor ambient temperature is between 0℃ and 5℃, the associated compressor's stable operating frequency is 92Hz. Furthermore, the air conditioner can match the stable operating frequency of the compressor with the air conditioner's model information, current operating mode information, and outdoor ambient temperature from the operating database, and determine this as the target operating frequency of the air conditioner compressor. In this way, the target operating frequency can be accurately determined by combining the air conditioner's model information, current operating mode information, and outdoor ambient temperature.

[0055] Optionally, after controlling the telescopic device to execute the initial air mass penetration strategy, the method further includes:

[0056] If the air outlet area of ​​the outdoor unit of the air conditioner is reduced to the first area and remains so for a second duration, the air conditioner control telescopic device retracts to the inside of the air outlet so that the air outlet area of ​​the outdoor unit of the air conditioner is restored to the initial area.

[0057] In this solution, if the air outlet area of ​​the outdoor unit shrinks to a first area for a second duration, and it is determined that the air blowing from the outdoor unit's outlet has penetrated the hot / cold air surrounding the outdoor unit, the air conditioner can control the retractable device to retract to the inside of the air outlet, thus restoring the outdoor unit's outlet area to its initial size. As an example, the second duration is 2 minutes. This method accurately determines the end time of the retractable device's initial airflow penetration strategy, meeting the user's energy-saving control requirements for the air conditioner.

[0058] Optionally, the system acquires the outdoor ambient temperature from an ambient temperature sensor and the current operating mode of the air conditioner. If the current operating mode is cooling mode, and the difference between the outdoor ambient temperature at the moment of the first air mass breakthrough and the outdoor ambient temperature acquired by the ambient temperature sensor is greater than a preset difference, the air conditioner can control the telescopic device to retract to the inside of the air conditioner's air outlet, so that the air outlet area of ​​the outdoor unit returns to its initial area. If the current operating mode is heating mode, and the difference between the outdoor ambient temperature acquired by the ambient temperature sensor and the outdoor ambient temperature at the moment of the first air mass breakthrough is greater than a preset difference, the air conditioner can control the telescopic device to retract to the inside of the air outlet, so that the air outlet area of ​​the outdoor unit returns to its initial area. As an example, the preset difference is 2℃. In this way, the timing for the telescopic device to execute the first air mass breakthrough strategy is accurately determined, meeting the user's energy-saving control needs for the air conditioner.

[0059] Figure 4 This is a schematic diagram of another method for controlling an outdoor unit of an air conditioner provided in this disclosure embodiment; combined with Figure 4 As shown, optionally, after the telescopic device executes the first air mass penetration command, it further includes:

[0060] S41, the air conditioner obtains the current outdoor ambient temperature, the current compressor operating frequency, and the current operating power of the air conditioner.

[0061] S42, under the condition that the current outdoor ambient temperature, current compressor operating frequency and current air conditioner operating power meet the secondary air mass breakdown conditions, the air conditioner determines the secondary air mass breakdown strategy of the outdoor unit.

[0062] S43, the air conditioning control telescopic device executes a secondary air mass penetration strategy.

[0063] In this solution, the air conditioner can again obtain the current outdoor ambient temperature, the current compressor operating frequency, and the current operating power of the air conditioner. Specifically, the air conditioner can obtain the current outdoor ambient temperature through an outdoor temperature sensor, and it can also determine the current compressor operating frequency and the current operating power of the air conditioner based on its operating parameter information. In this way, accurate acquisition of the current outdoor ambient temperature, the current compressor operating frequency, and the current operating power of the air conditioner can be achieved.

[0064] Furthermore, the air conditioner can determine the secondary air mass breakdown strategy for the outdoor unit based on the current outdoor ambient temperature, compressor operating frequency, and air conditioner's current operating power, provided these conditions meet the requirements for secondary air mass breakdown. This allows for precise determination of the secondary air mass breakdown strategy. After determining the strategy, the air conditioner can control the expansion joint to execute it. This allows for secondary control of the expansion joint based on the actual operating conditions of the air conditioner and the temperature around the outdoor unit, enabling more energy-efficient secondary air mass breakdown when a hot / cold air mass re-forms around the outdoor unit, thus precisely ensuring the heat exchange efficiency of the outdoor unit.

[0065] Optionally, the current outdoor ambient temperature, current compressor operating frequency, and current air conditioner operating power are determined to meet the secondary air mass breakdown condition by the following methods:

[0066] If the difference between the current outdoor ambient temperature and the outdoor ambient temperature at the moment of the first air mass breakdown is greater than the first threshold, the current compressor operating frequency is equal to the compressor operating frequency at the moment of the first air mass breakdown, and the ratio of the current operating power of the air conditioner to the operating power of the air conditioner at the moment of the first air mass breakdown is greater than the preset ratio, the air conditioner determines that the current outdoor ambient temperature, the current compressor operating frequency, and the current operating power of the air conditioner meet the conditions for the second air mass breakdown.

[0067] In this scheme, the outdoor ambient temperature at the moment of the first air mass breakdown is the outdoor ambient temperature immediately after the air conditioner has undergone the first air mass breakdown; the compressor operating frequency at the moment of the first air mass breakdown is the compressor operating frequency immediately after the air conditioner has undergone the first air mass breakdown; and the air conditioner operating power at the moment of the first air mass breakdown is the air conditioner operating power immediately after the air conditioner has undergone the first air mass breakdown. As an example, the first threshold is 3℃, and the preset ratio is 1.1. Specifically, if the difference between the current outdoor ambient temperature and the outdoor ambient temperature at the moment of the first air mass breakdown is greater than 3℃, the current compressor operating frequency is equal to the compressor operating frequency at the moment of the first air mass breakdown, and the ratio of the current air conditioner operating power to the air conditioner operating power at the moment of the first air mass breakdown is greater than 1.1, the air conditioner determines that the current outdoor ambient temperature, the current compressor operating frequency, and the current air conditioner operating power meet the conditions for a second air mass breakdown. In this way, it is possible to accurately determine whether the environmental conditions and operating conditions of the air conditioner meet the conditions for a second air mass breakdown.

[0068] Optionally, S42, the air conditioner determines the secondary air mass breakdown strategy for the outdoor unit, including:

[0069] If the difference between the current outdoor ambient temperature and the outdoor ambient temperature at the moment of the first air mass breakdown is greater than the second threshold, the air conditioner determines that the secondary air mass breakdown strategy of the outdoor unit is to control the telescopic device to execute the first air mass breakdown command, so that the telescopic device is controlled to extend from the inside of the air outlet of the outdoor unit towards the direction of blocking the air outlet until the air outlet area of ​​the outdoor unit is reduced to the first area.

[0070] If the difference between the current outdoor ambient temperature and the outdoor ambient temperature at the moment of the first air mass breakdown is not greater than the second threshold, the air conditioner determines that the secondary air mass breakdown strategy of the outdoor unit is to control the telescopic device to execute the second air mass breakdown command, so that the telescopic device is controlled to extend from the inside of the air outlet of the outdoor unit towards the direction of blocking the air outlet until the air outlet area of ​​the outdoor unit is reduced to the second area.

[0071] In this scheme, the outdoor ambient temperature at the moment of the first air mass breakthrough is the outdoor ambient temperature immediately after the air conditioner performs the first air mass breakthrough; the second threshold is 5℃. Specifically, when the difference between the current outdoor ambient temperature and the outdoor ambient temperature at the moment of the first air mass breakthrough is greater than 5℃, the air conditioner determines that the secondary air mass breakthrough strategy for the outdoor unit is to control the telescopic device to execute the first air mass breakthrough command, so that the telescopic device extends from the inside of the air outlet of the outdoor unit towards the direction of blocking the air outlet until the air outlet area of ​​the outdoor unit is reduced to the first area. Here, the first air mass breakthrough command includes controlling the telescopic device to extend from the inside of the air outlet of the outdoor unit towards the direction of blocking the air outlet until the air outlet area of ​​the outdoor unit is reduced to the first area. In one example, the first area can be determined in the following way: the air conditioner obtains the model information of the air conditioner; the air conditioner determines the initial air outlet size information based on its model information; the air conditioner calculates the initial area of ​​the initial air outlet based on the initial air outlet size information; the air conditioner uses the product of the first proportional coefficient and the initial area as the first area. The initial area is the standard area of ​​the air outlet of this air conditioner model, and the first proportionality coefficient is 1 / 4. In this way, the initial area can be accurately determined.

[0072] In this scheme, when the difference between the current outdoor ambient temperature and the outdoor ambient temperature at the moment of the first air mass breakdown is no greater than 5°C, the air conditioner determines the secondary air mass breakdown strategy for the outdoor unit as follows: control the telescopic device to execute the second air mass breakdown command, so that the telescopic device extends from the inside of the air outlet of the outdoor unit towards the direction of blocking the air outlet until the air outlet area of ​​the outdoor unit is reduced to the second area. Here, the second air mass breakdown command includes controlling the telescopic device to extend from the inside of the air outlet of the outdoor unit towards the direction of blocking the air outlet until the air outlet area of ​​the outdoor unit is reduced to the second area. In one example, the second area can be determined as follows: the air conditioner obtains the model information of the air conditioner; the air conditioner determines the initial air outlet size information based on its model information; the air conditioner calculates the initial area of ​​the initial air outlet based on the initial air outlet size information; the air conditioner uses the product of the second proportional coefficient and the initial area as the second area. Wherein, the initial area is the standard area of ​​the air outlet of this model of air conditioner, and the second proportional coefficient is 9 / 16. In this way, the second area can be accurately determined.

[0073] In this way, by combining the current outdoor ambient temperature with the specific outdoor ambient temperature at the moment of the first air mass breakthrough, the secondary air mass breakthrough strategy of the air conditioner outdoor unit can be determined more accurately, so that the secondary air mass breakthrough strategy determined in this way is more in line with the operating conditions of the air conditioner outdoor unit.

[0074] In this solution, in order to obtain the timing for determining the air mass breakdown strategy again after the air conditioning control telescopic device executes the secondary air mass breakdown strategy, optionally, after the air conditioning control telescopic device executes the secondary air mass breakdown strategy, the solution further includes:

[0075] The air conditioner obtains the first interval between the air conditioner's execution of the secondary breakdown strategy and the initial breakdown strategy;

[0076] After the first interval, the air conditioner determines whether the current outdoor ambient temperature, the current compressor operating frequency, and the current operating power of the air conditioner meet the conditions for secondary air mass breakdown.

[0077] If the current outdoor ambient temperature, the current compressor operating frequency, and the current air conditioner operating power meet the secondary air mass breakdown conditions, then while executing the air mass breakdown strategy, the time interval for determining whether the outdoor ambient temperature, compressor operating frequency, and air conditioner operating power meet the secondary air mass breakdown conditions again is the first interval duration * 1 / 2.

[0078] If the current outdoor ambient temperature, the current compressor operating frequency, and the current air conditioner operating power do not meet the secondary air mass breakdown condition, then the time interval for determining whether the outdoor ambient temperature, compressor operating frequency, and air conditioner operating power meet the secondary air mass breakdown condition again is the first interval duration * 2.

[0079] In this way, after the air conditioner executes the secondary air mass breakdown strategy, it can accurately determine when the air conditioner should make another environmental parameter judgment. Based on the specific judgment results, the interval between multiple strategy judgments can be adjusted more precisely to meet the user's energy-saving control needs for the air conditioner.

[0080] Figure 5 This is a schematic diagram of a device for controlling an outdoor unit of an air conditioner, provided in an embodiment of this disclosure; combined with Figure 5 As shown, this embodiment of the present disclosure provides an apparatus for controlling an outdoor unit of an air conditioner, including an acquisition module 51, a determination module 52, and a control module 53. The acquisition module 51 is configured to acquire the outdoor ambient temperature and the operating frequency of the air conditioner compressor; the determination module 52 is configured to determine the target operating frequency of the air conditioner compressor based on the outdoor ambient temperature; the control module 53 is configured to control a telescopic device to execute a first air mass penetration strategy when the operating frequency reaches the target operating frequency and continues to operate for a first duration, so that the telescopic device extends controlled from the inside of the air outlet of the outdoor unit towards the direction of blocking the air outlet until the air outlet area of ​​the outdoor unit is reduced to a first area.

[0081] The device for controlling an outdoor air conditioner unit provided in this disclosure acquires the outdoor ambient temperature and the operating frequency of the air conditioner compressor. Based on the outdoor ambient temperature, a target operating frequency for the air conditioner compressor is determined. When the operating frequency reaches the target frequency and continues to operate for a first duration, the telescopic device is controlled to execute a first air mass breakthrough strategy. This causes the telescopic device to extend controlled from the inside of the air outlet of the outdoor air conditioner unit towards the direction of blocking the air outlet until the area of ​​the air outlet of the outdoor air conditioner unit is reduced to a first area. With this solution, even when a telescopic device is installed inside the air outlet of the outdoor air conditioner unit, after the air conditioner is running stably, the telescopic device can be controlled to execute a first air mass breakthrough strategy. This allows the telescopic device to extend controlled from the inside of the air outlet of the outdoor air conditioner unit towards the direction of blocking the air outlet, thereby increasing the air pressure at the outdoor unit's air outlet by reducing the air outlet area. This enables precise and effective breakthrough of the formed hot / cold air mass, further improving the heat exchange efficiency of the outdoor air conditioner unit.
