[0020] Figure 1 is a schematic flow chart of a drying control method of an air conditioner according to an embodiment of the present application, as Figure 1 shown, the present embodiment provides a drying control method of an air conditioner, which can generally comprise: step S101, obtaining indoor humidity and indoor temperature when the operation mode of the air conditioner for drying is a drying refrigeration mode; step S102, determining a target humidity according to the indoor humidity; step S103, determining a dew point temperature according to the target humidity and the indoor temperature; step S104, controlling the compressor and / or the indoor fan of the air conditioner according to the dew point temperature.

[0021] Specifically, the target humidity refers to a humidity level that the indoor environment is desired to be controlled to. The dew point temperature is a saturation temperature corresponding to the air at the current indoor temperature reaching the target humidity, and it is a key parameter determining the dehumidification efficiency. Step S103 is specifically: looking up or calculating the corresponding dew point temperature according to the indoor temperature and the target humidity. Step S104 refers to: controlling the frequency of the compressor according to the dew point temperature, so as to control the temperature of the indoor heat exchanger; and / or adjusting the rotating speed of the indoor fan to control the air supply amount of the dry air.

[0022] In the embodiment, a control method in a refrigeration mode for drying is disclosed. The method sets a target humidity according to the real-time indoor humidity, and determines a dew point temperature according to the target humidity and the current indoor temperature, and then takes the dew point temperature as a control target, automatically adjusts the frequency of the compressor to control the dehumidification intensity, and / or automatically adjusts the rotating speed of the indoor fan to control the air supply amount. Therefore, the air conditioner can adaptively adjust the dehumidification intensity and the air supply amount according to the real-time changes of the indoor temperature and the indoor humidity in the clothes drying process, thereby significantly shortening the clothes drying time, ensuring a good drying effect, and improving the user experience. At the same time, the scheme does not need to increase additional hardware, but only needs to optimize the control logic to realize performance improvement, and has high efficiency and cost advantage.

[0023] In some optional embodiments of the present application, as shown in Figure 2 According to the dew point temperature, the compressor of the air conditioner can generally include: Step S1041, determining a target temperature of the indoor heat exchanger according to the dew point temperature; Step S1042, obtaining the temperature of the indoor heat exchanger; Step S1043, controlling the compressor according to the temperature of the indoor heat exchanger and the target temperature.

[0024] Specifically, in step S1041, the target temperature of the indoor heat exchanger is less than or equal to the dew point temperature, so as to ensure that the water vapor in the air can effectively condense on the surface thereof. In step S1043, by comparing the actual temperature of the indoor heat exchanger with the target temperature, the refrigeration output (frequency) of the compressor is dynamically adjusted, so that the actual temperature of the indoor heat exchanger approaches the target temperature, and the indoor heat exchanger is ensured to continuously work in the optimal dehumidification temperature range, thereby ensuring the high efficiency, stability and energy saving of the drying process.

[0025] In this embodiment, by converting the dew point temperature into control of the indoor heat exchanger temperature, the system can dynamically adjust the compressor frequency, so that the indoor heat exchanger (evaporator) is always maintained at the optimal dehumidification temperature. This not only achieves more accurate and efficient dehumidification, but also achieves energy saving and equipment protection by avoiding frequent start-stop or long-term high-load operation of the compressor; at the same time, the system can automatically resist environmental fluctuations to ensure stable and reliable drying process, ultimately improving the drying efficiency while significantly improving the user experience.

[0026] In some optional embodiments of the present application, the temperature of the indoor heat exchanger refers to the temperature of the indoor coil. The target temperature of the indoor heat exchanger refers to the target temperature of the indoor coil.

[0027] In some optional embodiments of the present application, controlling the compressor according to the temperature and the target temperature of the indoor heat exchanger can generally include: adjusting the frequency of the compressor through a PID control algorithm according to the deviation of the temperature and the target temperature of the indoor heat exchanger.

[0028] Specifically, when the temperature of the indoor heat exchanger is higher than the target temperature (positive deviation), the compressor frequency is increased to enhance refrigeration, so that the temperature of the indoor heat exchanger decreases; when the temperature of the indoor heat exchanger approaches or reaches the target temperature, the current frequency is reduced or maintained. Through the above control, the temperature of the indoor heat exchanger can be quickly and accurately maintained near the target temperature, thereby achieving stable and efficient dehumidification effect.

[0029] In some optional embodiments of the present application, when controlling the compressor of the air conditioner according to the dew point temperature, it can generally further include: controlling the indoor fan according to the indoor humidity; and when the indoor humidity is greater than a first preset humidity, the speed of the indoor fan is a first speed; when the indoor humidity is less than a second preset humidity, the speed of the indoor fan is a second speed; the second preset humidity is less than the first preset humidity, and the first speed is less than the second speed.

[0030] In this embodiment, the indoor fan is controlled according to the indoor humidity, which realizes the optimization of air supply strategy in different stages of the drying process. In the early stage of drying or when the environmental humidity is very high (greater than the first preset humidity), the indoor fan executes a lower first speed, which can reduce the air flow rate, so that the humid air stays on the surface of the indoor heat exchanger for a longer time, thereby significantly improving the efficiency of condensation dehumidification, and preferentially rapidly reducing the indoor environmental humidity to make the water in the clothes evaporate better. When the environmental humidity is reduced to below the second preset humidity, the indoor fan is controlled to switch to a higher second speed, which increases the air supply volume, thereby enhancing the flow and circulation of dry air, which can more effectively carry away the saturated wet air on the surface of the clothes, accelerate the evaporation of the water in the clothes and the diffusion to the environmental air, thereby significantly shortening the overall drying time.

[0031] In some optional embodiments of the present application, when the indoor humidity is greater than the first preset humidity, the target humidity is a third preset humidity, and the third preset humidity is less than the first preset humidity.

[0032] When the indoor humidity is less than the second preset humidity, the target humidity is a fourth preset humidity, the second preset humidity is equal to the fourth preset humidity, the fourth preset humidity is greater than the third preset humidity, and the second preset humidity is less than the first preset humidity.

[0033] In the present embodiment, the target humidity in different stages of the drying process is dynamically adjusted based on the indoor humidity, so as to realize fine and adaptive optimization of the drying strategy. On the one hand, in a high-humidity working condition (indoor humidity > first preset humidity), a lower third preset humidity is used as the target humidity, which corresponds to a lower target dew point temperature, so that the air conditioner runs with stronger refrigeration and dehumidification capacity, and the environmental humidity is preferentially reduced quickly to create favorable conditions for the evaporation of water in clothes. In a low-humidity working condition (indoor humidity < second preset humidity), the target humidity is switched to a higher fourth preset humidity, which corresponds to a higher target dew point temperature; this setting allows the system to appropriately increase the temperature of the indoor heat exchanger while meeting the dehumidification requirement, so as to blow out dry air with a relatively higher temperature, which is more conducive to the evaporation of water in clothes. The above adaptive control strategy significantly improves the overall drying efficiency. On the other hand, in a low-humidity working condition, switching the target humidity to a higher fourth preset humidity helps to reduce the compressor load and operating frequency, avoiding energy waste caused by excessive refrigeration, and realizing energy-saving operation.

[0034] In some optional embodiments of the present application, the first preset humidity is 65% to 75%, and the second preset humidity is 55% to 65%.

[0035] Preferably, the first preset humidity is 70%, and the second preset humidity is 60%.

[0036] In some optional embodiments of the present application, the third preset humidity is 45% to 55%, and the fourth preset humidity is 56% to 65%.

[0037] Preferably, the third preset humidity is 50%, and the fourth preset humidity is 60%.

[0038] In some alternative embodiments of the present application, the drying control method of the air conditioner further comprises: when the drying refrigeration mode starts to run, entering the step of determining the target humidity according to the indoor humidity; and when the indoor humidity is greater than or equal to the second preset humidity and less than or equal to the first preset humidity, the target humidity is the third preset humidity, and the rotating speed of the indoor fan is the first rotating speed; when the indoor humidity increases and is greater than the first preset humidity, entering the step of determining the target humidity according to the indoor humidity; and when the indoor humidity decreases and is less than the second preset humidity, entering the step of determining the target humidity according to the indoor humidity.

[0039] In the present embodiment, a state initialization and switching logic in the starting and running of the drying refrigeration mode is provided. Since the target humidity and the rotating speed of the indoor fan corresponding to the condition of "the second preset humidity ≤ the indoor humidity ≤ the first preset humidity" are consistent with the target humidity and the rotating speed of the indoor fan corresponding to the condition of "the indoor humidity > the first preset humidity", the present embodiment can avoid frequent switching of the rotating speed of the indoor fan and the target humidity, and guarantee the stability and reliability of the running of the air conditioner.

[0040] In some alternative embodiments of the present application, as shown in Figure 3 the drying control method of the air conditioner further comprises: Step S210, acquiring the outdoor environment temperature and the indoor temperature; Step S220, determining the running mode of the air conditioner for drying according to the outdoor environment temperature and the indoor temperature; the running mode comprises a drying refrigeration mode and a drying heating mode.

[0041] In the present embodiment, the drying refrigeration mode or the drying heating mode is adopted according to the indoor and outdoor temperatures and the indoor environment temperature, which is beneficial to realize all-weather and all-season high efficiency application of the drying function of the air conditioner, and significantly improves the user experience.

[0042] In some alternative embodiments of the present application, determining the running mode of the air conditioner for drying according to the outdoor environment temperature and the indoor temperature comprises: when the outdoor environment temperature is lower than a first preset temperature, determining that the running mode of the air conditioner for drying is the drying heating mode; when the outdoor environment temperature is lower than a second preset temperature and the indoor temperature is lower than a third preset temperature, determining that the running mode of the air conditioner for drying is the drying heating mode; the second preset temperature is greater than the first preset temperature; when the outdoor environment temperature is higher than or equal to the second preset temperature, determining that the running mode of the air conditioner for drying is the drying refrigeration mode; and when the outdoor environment temperature is higher than or equal to the first preset temperature and the indoor temperature is higher than or equal to the third preset temperature, determining that the running mode of the air conditioner for drying is the drying refrigeration mode.

[0043] The first preset temperature, the second preset temperature and the third preset temperature can be set and selected according to actual application requirements. For example, the first preset temperature can be 5℃, and the second preset temperature and the third preset temperature can both be 16℃.

[0044] The embodiment provides precise decision logic based on quantitative parameters for selection of the drying mode by setting specific temperature thresholds and combination judgment conditions, and improves the determinacy and adaptability of the control system. Specifically, in a cold environment (outdoor temperature is lower than the first preset temperature) or a humid and cold environment (outdoor temperature is lower than the second preset temperature and indoor temperature is lower than the third preset temperature), the drying heating mode is selected to ensure that the effective hot air drying process can be started under the condition of low temperature and high humidity. Under the condition of suitable temperature, the drying refrigeration mode with higher energy efficiency is adopted to accelerate drying by active dehumidification. The above method realizes the optimal balance between drying efficiency and operating energy efficiency under different environmental conditions.

[0045] In some optional embodiments of the present application, as shown in Figure 4 The drying control method of the air conditioner further includes: In step S310, when the operating mode of the air conditioner for drying is the drying heating mode, the indoor temperature, the outdoor environment temperature and the remaining drying time are obtained. In step S320, when the indoor temperature reaches the fourth preset temperature and lasts for a preset time, the drying refrigeration mode is entered. In step S330, when the outdoor temperature reaches the fifth preset temperature, the drying refrigeration mode is entered. In step S340, when the remaining drying time is reduced to a preset remaining time, the drying refrigeration mode is entered.

[0046] The embodiment provides three judgment conditions for switching from the drying heating mode to the drying refrigeration mode during the operation of the drying heating mode. During the operation, if any of the conditions is met, the air conditioner will intelligently switch the operating mode from the drying heating mode to the drying refrigeration mode.

[0047] Compared with the single continuous heating strategy, the composite drying strategy of “first heating and then refrigeration” has the following beneficial effects: on the one hand, switching when the indoor temperature is too high can effectively prevent the continuous heating from causing the indoor temperature to be too high, thereby improving the comfort and safety of use. On the other hand, switching when the outdoor temperature significantly rises reflects the dynamic adaptation of the air conditioner to the external environment, which can select the working mode with higher energy efficiency under the current conditions, thereby realizing energy saving optimization. On the other hand, switching when the drying program is close to the end can use the refrigeration dehumidification function to remove the accumulated moisture in the early stage and cool and shape the clothes, thereby avoiding the clothes from being damp after being taken out due to cold, and ensuring that the clothes are finally dry, fluffy, and have a good touch and effect.

[0048] In some optional embodiments of the present application, the fourth preset temperature, the fifth preset temperature, the preset time length and the preset remaining time length involved in steps S320, S330 and S340 can be specifically set according to actual product design and user experience requirements.

[0049] Preferably, the fourth preset temperature is 25℃, the fifth preset temperature is 20℃, the preset time length is 2 min, and the preset remaining time length is 30 min. This preferred parameter combination achieves a good balance between engineering practice and user experience. Among them, the indoor temperature switching threshold of 25℃ can effectively prevent the room temperature from overheating; the outdoor temperature threshold of 20℃ can timely capture the significant warming of the external environment; the continuous judgment time of 2 minutes can avoid false switching caused by instantaneous temperature fluctuations; and the preset remaining time length of 30 minutes reserves sufficient and efficient action time for subsequent refrigeration and dehumidification and clothes cooling and shaping.

[0050] In some optional embodiments of the present application, the control method further comprises: when the operation mode of the air conditioner for drying is the drying heating mode, controlling the compressor to operate at a preset frequency, and controlling the indoor fan to operate at a third rotating speed.

[0051] Preferably, the third rotating speed is greater than the second rotating speed. Further preferably, the preset frequency is 25 Hz.

[0052] In some optional embodiments of the present application, the control method further comprises: obtaining a total drying time length set by a user; taking the total drying time length set by the user as a target total drying time length, and drying according to the target total drying time length. Specifically, when the user does not set the total drying time length, taking a preset total drying time length as the target total drying time length, and drying according to the target total drying time length. The preset total drying time length is 1 to 4 hours. Preferably, the preset total drying time length is 3 hours.

[0053] In some optional embodiments of the present application, as shown in Figure 5 A drying control method of an air conditioner can include: Step S1, when the air conditioner receives a drying function start signal, obtaining an outdoor environment temperature and an indoor temperature; Step S2, if any of the following conditions is met, the operation mode is determined to be the drying heating mode: First condition: the outdoor environment temperature < 5℃; Second condition: the outdoor environment temperature < 16℃ and the indoor temperature < 16℃; Step S3, if the first condition and the second condition are not met, enter the drying refrigeration mode; Step S21, control the compressor to operate at a fixed frequency (such as 25 Hz), and control the indoor fan to operate at a third rotating speed to continuously blow hot air; Step S22, during the heating mode operation, if any of the following conditions is met, the system automatically switches to the drying refrigeration mode: Condition A: the indoor temperature ≥ 25℃ for 2 minutes; Condition B: the outdoor ambient temperature > 20℃; Condition C: the remaining drying time ≤ 30 minutes; Step S31, the indoor temperature and the indoor humidity are obtained; Step S32, when the indoor humidity > 70%, or when 60% ≤ the indoor humidity ≤ 70%, the target humidity is set to 50%, and the dew point temperature is obtained according to the indoor temperature and the target humidity, so that the target temperature of the indoor heat exchanger is equal to the dew point temperature; at the same time, the indoor fan is controlled to operate at the first rotating speed; Step S33, when the indoor humidity < 60%, the target humidity is set to 60%, and the dew point temperature is obtained according to the indoor temperature and the target humidity, so that the target temperature of the indoor heat exchanger is equal to the dew point temperature; at the same time, the indoor fan is controlled to operate at the second rotating speed; wherein the third rotating speed > the second rotating speed > the first rotating speed; Step S34, the temperature of the indoor heat exchanger is obtained; Step S35, according to the deviation between the temperature of the indoor heat exchanger and the target temperature, the frequency of the compressor is adjusted through the PID control algorithm, so that the temperature of the indoor heat exchanger approaches the target temperature; Step S4, when the cumulative drying operation time reaches the target drying time, the air conditioner is controlled to stop the drying operation.

[0054] The air conditioner drying control method provided in this embodiment realizes efficient and reliable drying of clothes under various environmental conditions through a complete set of intelligent judgment and execution logic.

[0055] Specifically, the method first automatically selects the most suitable drying mode according to the indoor and outdoor temperatures. When the outdoor temperature is very low (below 5℃) or the indoor and outdoor temperatures are both low (both below 16℃), the system will start the heating mode to blow hot air at a fixed frequency and a high speed to directly heat the clothes and the environment. During the heating operation, if the indoor temperature is too high (reaches 25℃ and lasts for 2 minutes), the outdoor temperature rises (exceeds 20℃), or the drying is about to end (30 minutes remaining), the system will automatically switch to the refrigeration mode.

[0056] If the heating condition is not met, the system directly enters the refrigeration mode. In this mode, the system continuously monitors the indoor humidity. When the humidity is high, the indoor fan operates at a low speed, and a lower dehumidification target is set to preferentially and strongly reduce the air humidity. When the humidity is low, the indoor fan speed is increased, and the dehumidification target is moderately relaxed, and the system blows dry air with a slightly higher temperature to accelerate the removal of moisture from the clothes.

[0057] During the whole refrigeration process, the system compares the actual temperature of the indoor heat exchanger with the target temperature in real time, and dynamically adjusts the frequency of the compressor by using the PID algorithm, so as to ensure that the dehumidification efficiency is always in the optimal state.

[0058] In the embodiment, by selecting the intelligent drying mode, it is ensured that the heating mode is preferentially used to effectively start the drying in low-temperature weather, so as to solve the problem of low drying efficiency in winter. Meanwhile, in the refrigeration and drying stage, the strong dehumidification or the accelerated drying strategy can be adaptively switched according to the indoor humidity change, and the temperature of the indoor heat exchanger is accurately controlled, so that the drying speed is significantly improved and energy saving and consumption reduction are realized. In addition, by switching to the drying refrigeration mode after the late stage of the heating mode, the residual moisture can be effectively removed and the clothes can be cooled, so that the "re-humidification" phenomenon after the clothes are taken out is avoided, and the user experience is comprehensively improved.
