Description

Technical Field

[0001] This invention relates to the field of air conditioners, and more specifically, to a control method, device, air conditioner, and storage medium for preventing water from blowing or dripping. Background Technology

[0002] During the operation of air conditioners, condensation and dripping water often occur in users' rooms in high-humidity areas, causing adverse effects and a poor user experience.

[0003] Condensation in a room is usually caused by an imbalance in the heat exchange of each heat exchange block, which leads to the convergence of hot and cold air and causes secondary condensation, or by excessive humidity. In addition, the large temperature difference between the air and the surface of the fins and copper pipes causes the condensation to occur too quickly. When the wind speed is too high, it will cause water to blow, and when the wind speed is too slow, it will cause water to drip. Summary of the Invention

[0004] The problem solved by this invention is that, in the prior art, in high-humidity areas, air conditioners in users' rooms often experience condensation and dripping water or water blowing, causing adverse effects.

[0005] To address the above problems, this invention provides a control method for preventing water blowing and dripping, used in the refrigeration control of an air conditioner. The control method includes:

[0006] The system detects the indoor ambient humidity d and determines the humidity range of the indoor environment based on d. Based on the humidity range, it activates the corresponding anti-drip mode and / or anti-blowing mode. The anti-drip mode includes: detecting the indoor ambient temperature ta and obtaining a set target temperature t0; adjusting the upper limit of the air conditioner's operating frequency based on the relationship between the indoor ambient temperature ta and the set target temperature t0 to prevent the air conditioner from dripping water. The anti-blowing mode includes: detecting the fin edge temperature tp and the outlet air temperature tc; adjusting the upper limit of the fan speed based on the detection results to prevent the air conditioner from blowing water.

[0007] By adjusting the above settings, when there is a risk of dripping, the operating frequency of the air conditioner can be adjusted accordingly to reduce the temperature difference between the air conditioner and the ambient temperature, thereby reducing the condensation rate. This allows sufficient time for the condensation to flow into the water tank along the fins and then be discharged through the drain pipe, preventing dripping due to insufficient water conduction from the fins. As the condensation is discharged, the humidity in the space can also be reduced slowly, improving human comfort. In addition, during the operation of the air conditioner, the condensation formed on the edge of the fins is very easy to detach from the fins and be carried out by high-speed air, resulting in water blowing from the air conditioner. Adjusting the upper limit of the fan speed can significantly reduce the probability of condensation being carried out by the air, thereby avoiding or mitigating water blowing. In this application, by controlling the air conditioner's operating frequency and fan speed in combination, the dripping and water blowing phenomena during the cooling operation of the air conditioner can be eliminated or mitigated.

[0008] Further, "judging the humidity range of the indoor environment according to the indoor environmental humidity" includes:

[0009] Judging the magnitude relationship between the indoor environmental humidity d and the first humidity threshold d1 and the second humidity threshold d2;

[0010] When d > d2, judging that the indoor environment is a high humidity scenario;

[0011] When d1 ≤ d ≤ d2, judging that the indoor environment is a medium-high humidity scenario;

[0012] When d < d1, judging that the indoor environment is a low humidity scenario;

[0013] Wherein, d1 and d2 are preset values, and d1 < d2.

[0014] When the indoor environment is a low humidity scenario, the human body feels comfortable, and the condensation generation speed of the air conditioner is also relatively slow. It can be guided into the drain pipe through the fins and discharged in time, without dripping or blowing water, and a good user experience can be obtained without corresponding control. When the indoor environment is a medium-high humidity scenario, the condensation generation speed is relatively fast, and some condensation that来不及导入排水管的凝露会产生滴水和 / 或吹水的情况,需要采用相应的措施控制其产生速度,以降低或消除滴水和 / 或吹水的现象;当室内环境为高湿度场景时,凝露产生的速度极快,很容易出现滴水和 / 或吹水的现象,且短时间内无法快速消除,需要采用相应的需要采用相应的措施降低滴水和 / 或吹水的现象。

[0015] Further, the anti-dripping mode includes:

[0016] Calculating the difference between the indoor environmental temperature ta and the set target temperature t0, denoted as the room temperature difference △t = ta - t0;

[0017] Determining the corresponding preset room temperature difference threshold according to the humidity range of the indoor environment;

[0018] Judging the magnitude relationship between △t and the preset room temperature difference threshold, and adjusting the upper limit of the operating frequency of the air conditioner according to the judgment result.

[0019] Setting the upper limit of the operating frequency of the corresponding air conditioner according to the humidity range of the indoor environment and the magnitude relationship of △t, so that the air conditioner operates differentially according to the indoor humidity situation and the difference between the indoor environmental temperature and the set target temperature, so that it can adjust the corresponding operating strategy according to the specific situation, so as to reduce the condensation generation speed when the humidity is relatively high and eliminate or reduce the dripping situation during the operation of the air conditioner.

[0020] It should be noted that there seems to be some text that is not fully formed or contains incorrect expressions in the original Chinese text, such as "来不及导入排水管的凝露会产生滴水和 / 或吹水的情况,需要采用相应的措施控制其产生速度,以降低或消除滴水和 / 或吹水的现象;当室内环境为高湿度场景时,凝露产生的速度极快,很容易出现滴水和 / 或吹水的现象,且短时间内无法快速消除,需要采用相应的需要采用相应的措施降低滴水和 / 或吹水的现象。" which may need to be corrected for a more accurate translation. The above translation is based on the existing text as much as possible.Furthermore, when the indoor environment is a high humidity scenario, the preset room temperature difference threshold includes a first preset room temperature difference threshold Δt1 and a second preset room temperature difference threshold Δt2, where Δt1 < Δt2. "Adjusting the upper limit of the air conditioner's operating frequency based on the judgment result" includes:

[0021] When △t≤△t1, the upper limit of the air conditioner's operating frequency is adjusted to the first percentage a of the default upper limit of the frequency;

[0022] When △t1 < △t < △t2, adjust the upper limit of the air conditioner's operating frequency to the second percentage b of the default upper limit of the frequency;

[0023] When Δt≥Δt2, the upper limit of the air conditioner's operating frequency is adjusted to the third percentage c of the default upper limit of the frequency.

[0024] When the indoor environment is a medium-high humidity scenario, the preset room temperature difference threshold includes a third preset room temperature difference threshold Δt3 and a fourth preset room temperature difference threshold Δt4, where Δt3 < Δt4. "Adjusting the upper limit of the air conditioner's operating frequency based on the judgment result" includes:

[0025] When △t≤△t3, the upper limit of the air conditioner's operating frequency is adjusted to the fourth percentage d of the default upper limit of frequency;

[0026] When △t3 < △t < △t4, adjust the upper limit of the air conditioner's operating frequency to the fifth percentage e of the default upper limit of the frequency;

[0027] When △t≥△t4, the upper limit of the air conditioner's operating frequency will be adjusted to the sixth percentage of the default upper limit, f.

[0028] Where d>e>f≥a>b>c, and a, b, c, d, e, f, △t1, △t2, △t3, and △t4 are all preset values.

[0029] When Δt ≥ Δt2, the required cooling capacity indoors is large, and the compressor operating frequency tends to increase. Excessive compressor operating frequency leads to rapid condensation and severe dripping. In this case, the upper limit of the air conditioner's operating frequency needs to be set lower to prevent it from increasing its operating frequency to meet cooling demand. When Δt1 < Δt < Δt2, the required cooling capacity indoors decreases, and the upper limit of the compressor's operating frequency can be appropriately increased to increase cooling capacity while eliminating or reducing dripping. When Δt ≤ Δt1, the required cooling capacity is small, and the upper limit of the compressor's operating frequency can be further increased to quickly bring the indoor ambient temperature close to the set target temperature while eliminating or reducing dripping, thus improving the user experience. Since the ambient humidity in high humidity scenarios is higher than in medium-high humidity scenarios, condensation occurs faster. Therefore, in high humidity scenarios, the upper limit of the air conditioner's operating frequency needs to be set lower than in medium-high humidity scenarios to suppress condensation and eliminate or reduce dripping.

[0030] Furthermore, the anti-blowing mode includes:

[0031] Calculate the difference between the fin edge temperature tp and the outlet air temperature tc, and denot it as the outlet air temperature difference Δtc = tc - tp;

[0032] The corresponding preset air outlet temperature difference threshold is determined based on the humidity range of the indoor environment.

[0033] Determine the relationship between Δtc and the preset outlet air temperature difference threshold, and adjust the upper limit of the air conditioner's fan speed operation based on the determination result.

[0034] By comprehensively judging the indoor humidity, fin edge temperature, and outlet air temperature, adjusting the air conditioner's fan speed can effectively reduce condensation rate and fan speed, thereby eliminating or mitigating water blowing phenomenon.

[0035] Furthermore, when the indoor environment is a high humidity scenario, the preset outlet air temperature difference threshold includes a first preset outlet air temperature difference threshold △tc1 and a second preset outlet air temperature difference threshold △tc2, where △tc1 < △tc2. "Adjusting the upper limit of the air conditioner's fan speed based on the judgment result" includes:

[0036] When △tc≤△tc1, adjust the upper limit of the air conditioner's fan speed to the high setting;

[0037] When △tc1<△tc<△tc2, adjust the upper limit of the air conditioner's fan speed to medium.

[0038] When △tc≥△tc2, adjust the upper limit of the air conditioner's fan speed to the low setting;

[0039] When the indoor environment is a medium-high humidity scenario, the preset outlet air temperature difference threshold includes a third preset outlet air temperature difference threshold △tc3 and a fourth preset outlet air temperature difference threshold △tc4, where △tc3 < △tc4. "Adjusting the upper limit of the air conditioner's fan speed based on the judgment result" includes:

[0040] When Δtc≤Δtc3, there is no limit to the upper limit of wind speed;

[0041] When △tc3<△tc<△tc4, adjust the upper limit of the air conditioner's fan speed to the high setting;

[0042] When △tc≥△tc4, adjust the upper limit of the air conditioner's fan speed to medium speed.

[0043] Among them, △tc1, △tc2, △tc3, and △tc4 are all preset values, and △tc3 < △tc1.

[0044] When Δtc ≥ Δtc2, the temperature difference between the fin edge and the air outlet is large, resulting in rapid condensation and a tendency for water to blow out. In this case, setting the air conditioner's fan speed to a low setting can reduce the amount of condensation carried in the airflow, thus eliminating or mitigating the water blowing phenomenon. When Δtc1 < Δtc < Δtc2, the temperature difference between the fin edge and the air outlet decreases, and the rate of condensation also decreases. The air conditioner's fan speed can be appropriately increased while reducing water blowing. When Δtc ≤ Δtc1, the temperature difference between the fin edge and the air outlet is small, and the rate of condensation is relatively low. The air conditioner's fan speed can be further increased to eliminate or mitigate water blowing while quickly bringing the indoor temperature close to the set target temperature, thus improving the user experience. Since the ambient humidity in high humidity scenarios is higher than in medium-high humidity scenarios, condensation occurs even faster. Therefore, in high humidity scenarios, a lower upper limit for fan speed is needed compared to medium-high humidity scenarios to reduce the amount of condensation blown out, thereby eliminating or mitigating water blowing.

[0045] Furthermore, after each preset time of operation in the anti-drip mode and / or anti-blowing mode, the indoor humidity is re-detected, and the humidity range is determined. Based on the humidity range of the indoor environment, the corresponding anti-drip mode and / or anti-blowing mode is adjusted.

[0046] After the air conditioner has been running for a period of time, the indoor humidity will continue to drop as moisture in the indoor environment continues to condense and be discharged. Since the anti-drip mode and / or anti-blowing mode have a certain impact on the cooling capacity of the air conditioner, readjusting the corresponding anti-drip mode and / or anti-blowing mode according to the change in indoor humidity can eliminate or reduce dripping and blowing phenomena while improving the cooling effect of the air conditioner, thereby improving the user experience.

[0047] The present invention also discloses a heating defrosting control device, comprising:

[0048] Humidity detection module, used to detect indoor ambient humidity d;

[0049] A temperature monitoring module is used to detect at least the indoor ambient temperature ta, and / or the fin edge temperature tp and the outlet air temperature tc;

[0050] The judgment module is at least used to determine the humidity range of the indoor environment.

[0051] The anti-drip module is used to activate the corresponding anti-drip mode according to the humidity range described in the indoor environment humidity, and / or the anti-blowing module is used to activate the corresponding anti-blowing mode according to the humidity range described in the indoor environment humidity.

[0052] Through the collaboration between the above modules, the rate of condensation during air conditioning cooling is controlled, avoiding large-scale condensation in the room and water blowing or dripping from the air conditioner's air outlet due to excessively rapid cooling. This ensures a good user experience while achieving indoor cooling.

[0053] The present invention also discloses an air conditioner, including a computer-readable storage medium storing a computer program and a processor, wherein the computer program is read and executed by the processor to implement a control method for preventing water blowing and dripping as described above.

[0054] The air conditioner described above has the same advantages over the prior art as the aforementioned anti-drip water control method, and will not be repeated here.

[0055] The present invention also discloses a computer-readable storage medium storing a computer program, which is read and executed by a processor to implement a water-prevention and dripping control method as described above.

[0056] Compared with existing technologies, the water-prevention and dripping control method, device, air conditioner, and storage medium described in this invention have the following advantages:

[0057] This invention, through the setting of anti-drip and / or anti-blowing modes, adjusts the upper limit of the air conditioner's operating frequency and / or the upper limit of the fan speed according to the indoor humidity, thereby reducing the rate of condensation formation under medium to high humidity and eliminating or mitigating dripping and condensation phenomena caused by excessively rapid cooling of the air conditioner. The control method provided by this invention is simple and effective, effectively eliminating or mitigating dripping and condensation phenomena caused by excessively rapid cooling of the air conditioner, and improving the user experience.

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0062] The following describes in detail, with reference to the accompanying drawings, a method, apparatus, air conditioner, and storage medium for preventing water blowing and dripping according to an embodiment of the present invention.

[0063] Example 1

[0064] This embodiment provides a control method for preventing water blowing and dripping, used in the refrigeration control of an air conditioner, such as... Figure 1 As shown, the control method includes:

[0065] The system detects indoor humidity and determines the humidity range of the indoor environment. Based on the humidity range, it activates the corresponding anti-drip mode and / or anti-spray mode. The anti-drip mode includes: detecting the indoor ambient temperature ta and obtaining a set target temperature t0; adjusting the upper limit of the air conditioner's operating frequency based on the relationship between the indoor ambient temperature ta and the set target temperature t0 to prevent the air conditioner from dripping water. The anti-spray mode includes: detecting the fin edge temperature tp and the outlet air temperature tc; adjusting the upper limit of the fan speed based on the detection results to prevent the air conditioner from blowing water.

[0066] In a medium-high humidity scenario, if the air conditioner operates at high frequency for refrigeration, the temperature near the copper pipes of the indoor unit and from the air inlet side to the middle of the air outlet side of the indoor unit fins is about 10°C. The heat exchange temperature difference with the ambient temperature is too large. Near the copper pipes and from the air inlet side to the middle of the air outlet side of the fins, the condensation speed is extremely fast, and it is easy to form dripping water. To prevent the dripping water phenomenon, the operating frequency of the air conditioner can be adjusted accordingly to reduce the heat exchange temperature difference with the ambient temperature and lower the condensation speed, so that the condensation has sufficient time to flow down the fins into the water tank and then be discharged through the drain pipe, avoiding the dripping water phenomenon due to untimely water conduction by the fins. Because the condensation is discharged, the humidity in the space can also be slowly reduced, improving the comfort of the human body. In addition, during the operation of the air conditioner, the condensation formed at the edge of the fins is extremely easy to break away from the fins and be carried out by the high-speed air, forming the phenomenon of the air conditioner blowing water. At this time, adjusting the upper limit of the operating wind speed can significantly reduce the probability of the condensation being carried out by the air, thus avoiding or reducing the blowing water phenomenon. In this application, through the coordinated control of the operating frequency and operating wind speed of the air conditioner, the dripping water and blowing water phenomena during the refrigeration operation of the air conditioner can be eliminated or reduced. Among them, the operating frequency of the air conditioner refers to the operating frequency of the air conditioner compressor, the fin edge refers to the position near the air outlet on the air outlet side of the fins, the outlet temperature refers to the temperature of the indoor unit air outlet, and the wind speed refers to the air outlet speed of the indoor unit. The above control method is used for the refrigeration control of the air conditioner. Since the indoor heat exchanger is used for condensation during heating and no condensation will occur on its surface, there is no need to control for preventing dripping water or blowing water.

[0067] In this embodiment, "judging the humidity range of the indoor environment according to the indoor environmental humidity" includes:

[0068] Recording the indoor environmental humidity as d, and judging the size relationship between d and the first humidity threshold d1 and the second humidity threshold d2;

[0069] When d > d2, it is judged that the indoor environment is a high humidity scenario;

[0070] When d1 ≤ d ≤ d2, it is judged that the indoor environment is a medium-high humidity scenario;

[0071] When d < d1, it is judged that the indoor environment is a low humidity scenario;

[0072] Among them, d1 and d2 are preset values, and d1 < d2.

[0073] Studies have shown that the human body has a corresponding comfortable humidity range. Within this range, the human body feels relatively comfortable, while exceeding this range can burden breathing and significantly reduce comfort. In this embodiment, when the indoor environment is in a low humidity scenario, the human body feels comfortable, and the condensation rate of the air conditioner is also slow. It can be guided into the drain pipe by the fins and discharged in a timely manner, without dripping or blowing water. No special control is required, allowing the user to have a good experience. When the indoor environment is in a medium to high humidity scenario, the condensation rate is faster, and some condensation that cannot be drained into the drain pipe in time will cause dripping and / or blowing water. Appropriate measures need to be taken to control its generation rate to reduce or eliminate dripping and / or blowing water phenomena. When the indoor environment is in a high humidity scenario, the condensation rate is extremely fast, and dripping and / or blowing water phenomena are very likely to occur and cannot be quickly eliminated in a short time. Appropriate measures need to be taken to reduce dripping and / or blowing water phenomena.

[0074] As an alternative embodiment, d1 ranges from 62% to 68%, and d2 ranges from 72% to 78%. Studies have shown that the comfortable humidity range for the human body is 45% to 65%. When the humidity is higher than this range, it can burden the human body's breathing and significantly reduce the comfort of the skin. The condensation produced during the operation of the air conditioner is moisture condensed from the indoor environment. As the operating time continues, the indoor humidity will gradually decrease. Therefore, by controlling the operating frequency and / or fan speed of the air conditioner, the phenomenon of dripping and / or blowing water can be reduced or eliminated. By continuously running the air conditioner, the indoor humidity can be reduced to a suitable humidity range. Preferably, d1 is 65% and d2 is 75%.

[0075] As an embodiment of the present invention, the anti-drip mode includes:

[0076] Calculate the difference between the indoor ambient temperature ta and the set target temperature t0, and denot it as the room temperature difference Δt = ta - t0;

[0077] The corresponding preset room temperature difference threshold is determined based on the humidity range of the indoor environment.

[0078] Determine the relationship between Δt and the preset room temperature difference threshold, and adjust the upper limit of the air conditioner's operating frequency based on the determination result.

[0079] In this embodiment, the upper limit of the operating frequency of the air conditioner is set according to the humidity range of the indoor environment and the magnitude of Δt. This allows the air conditioner to operate differently based on the indoor humidity and the difference between the indoor ambient temperature and the set target temperature. This enables the air conditioner to adjust its operating strategy according to specific circumstances, thereby reducing the rate of condensation when the humidity is high and eliminating or reducing the dripping of water when the air conditioner is running.

[0080] As an embodiment of the present invention, such as Figure 2 As shown, when the indoor environment is a high humidity scenario, the preset room temperature difference threshold includes a first preset room temperature difference threshold Δt1 and a second preset room temperature difference threshold Δt2, where Δt1 < Δt2. "Adjusting the upper limit of the air conditioner's operating frequency based on the judgment result" includes:

[0081] When △t≤△t1, the upper limit of the air conditioner's operating frequency is adjusted to the first percentage a of the default upper limit of the frequency;

[0082] When △t1 < △t < △t2, adjust the upper limit of the air conditioner's operating frequency to the second percentage b of the default upper limit of the frequency;

[0083] When Δt≥Δt2, the upper limit of the air conditioner's operating frequency is adjusted to the third percentage c of the default upper limit of the frequency.

[0084] Where a>b>c, △t1<△t2, and a, b, c, △t1, and △t2 are all preset values.

[0085] It should be understood that the default frequency upper limit is the upper limit of the rated frequency of the air conditioner compressor when it is running normally without frequency adjustment, and its specific value can be determined according to the compressor model. As an optional example, the value range of Δt1 is 4 to 6℃, the value range of Δt2 is 8 to 12℃, the value range of a is 68% to 72%, the value range of b is 58% to 62%, and the value range of c is 48% to 52%. With the above settings, when the indoor environment is high-humidity and Δt ≥ Δt2, the required cooling capacity is large, and the compressor operating frequency is likely to increase. Excessive compressor operating frequency will lead to rapid condensation and severe dripping. In this case, the upper limit of the air conditioner's operating frequency needs to be set lower to avoid increasing the operating frequency under cooling demand. When Δt1 < Δt < Δt2, the required cooling capacity is reduced, and the upper limit of the compressor's operating frequency can be appropriately increased to increase cooling capacity while eliminating or reducing dripping. When Δt ≤ Δt1, the required cooling capacity is smaller, and the upper limit of the compressor's operating frequency can be further increased to allow the indoor temperature to quickly approach the set target temperature while eliminating or reducing dripping, thus improving the user experience. Preferably, Δt1 = 5℃, Δt2 = 10℃, a = 70%, b = 60%, and c = 50%.

[0086] As an embodiment of the present invention, when the indoor environment is a medium-high humidity scenario, the preset room temperature difference threshold includes a third preset room temperature difference threshold Δt3 and a fourth preset room temperature difference threshold Δt4, where Δt3 < Δt4. "Adjusting the upper limit of the air conditioner's operating frequency according to the judgment result" includes:

[0087] When △t≤△t3, the upper limit of the air conditioner's operating frequency is adjusted to the fourth percentage d of the default upper limit of frequency;

[0088] When △t3 < △t < △t4, adjust the upper limit of the air conditioner's operating frequency to the fifth percentage e of the default upper limit of the frequency;

[0089] When △t≥△t4, the upper limit of the air conditioner's operating frequency will be adjusted to the sixth percentage of the default upper limit, f.

[0090] Where d>e>f≥a>b>c, and d, e, f, △t3, and △t4 are all preset values.

[0091] As an optional example, the value range of Δt3 is 4 to 6℃, the value range of Δt4 is 8 to 12℃, the value range of d is 88% to 92%, the value range of e is 78% to 82%, and the value range of f is 68% to 72%. With the above settings, when the indoor environment is at medium to high humidity and Δt ≥ Δt4, the required cooling capacity is large, and the compressor operating frequency is likely to increase. Excessive compressor operating frequency will lead to condensation, although the rate of condensation is relatively slower compared to high humidity scenarios, dripping is still likely. In this case, the upper limit of the air conditioner's operating frequency needs to be set relatively low to avoid increasing the operating frequency under cooling demand. When Δt3 < Δt < Δt4, the required cooling capacity is reduced, and the upper limit of the compressor's operating frequency can be appropriately increased to increase cooling capacity while eliminating or reducing dripping. When Δt ≤ Δt3, the required cooling capacity is small, and the upper limit of the compressor's operating frequency can be further increased to allow the indoor temperature to quickly approach the set target temperature while eliminating or reducing dripping, thus improving the user experience. Preferably, Δt3 = 5℃, Δt4 = 10℃, d = 90%, e = 80%, and f = 70%. It should be noted that this embodiment does not limit the relationship between Δt1 and Δt3, or Δt2 and Δt4. They can be equal in pairs, different in all pairs, or one pair can be the same. It should be understood that because the ambient humidity in a high-humidity scenario is higher than that in a medium-high humidity scenario, condensation occurs faster. Therefore, in a high-humidity scenario, a lower upper limit for the air conditioner's operating frequency is needed compared to a medium-high humidity scenario to suppress the rate of condensation and thus eliminate or reduce dripping.

[0092] As an embodiment of the present invention, the anti-blowing mode includes:

[0093] Calculate the difference between the fin edge temperature tp and the outlet air temperature tc, and denot it as the outlet air temperature difference Δtc = tc - tp;

[0094] The corresponding preset air outlet temperature difference threshold is determined based on the humidity range of the indoor environment.

[0095] Determine the relationship between Δtc and the preset outlet air temperature difference threshold, and adjust the upper limit of the air conditioner's fan speed operation based on the determination result.

[0096] In existing technologies, water blowing from air conditioners often occurs because condensation at the fin edges detaches from the fins and is then carried out by the indoor unit's airflow. This is typically related to the condensation rate at the fin edges and the indoor airflow speed, which in turn is related to indoor humidity, air conditioner operating frequency, and airflow speed. This embodiment, by comprehensively assessing indoor humidity, fin edge temperature, and outlet air temperature, adjusts the air conditioner's airflow speed to effectively reduce condensation rate and airflow speed, thereby eliminating or mitigating the water blowing phenomenon.

[0097] As an embodiment of the present invention, such as Figure 3 As shown, when the indoor environment is a high humidity scenario, the preset outlet air temperature difference threshold includes a first preset outlet air temperature difference threshold △tc1 and a second preset outlet air temperature difference threshold △tc2, where △tc1 < △tc2. "Adjusting the upper limit of the air conditioner's fan speed based on the judgment result" includes:

[0098] When △tc≤△tc1, adjust the upper limit of the air conditioner's fan speed to the high setting;

[0099] When △tc1<△tc<△tc2, adjust the upper limit of the air conditioner's fan speed to medium.

[0100] When △tc≥△tc2, adjust the upper limit of the air conditioner's fan speed to the low setting;

[0101] Where △tc1 < △tc2, and △tc1 and △tc2 are both preset values.

[0102] It should be understood that the low, medium, and high wind speed settings are commonly used in the prior art and are not limited here. As an optional example, the value range of Δtc1 is 4–6℃, and the value range of Δtc2 is 6–8℃. With the above settings, when the indoor environment is high-humidity and Δtc ≥ Δtc2, the temperature difference between the fin edge and the air outlet is large, condensation occurs quickly, and water blowing is likely to occur. In this case, setting the air conditioner's fan speed to a low setting can reduce the amount of condensation carried in the air outlet, thereby eliminating or mitigating the water blowing phenomenon. When Δtc1 < Δtc < Δtc2, the temperature difference between the fin edge and the air outlet decreases, and the rate of condensation also decreases. The air conditioner's operating fan speed can be appropriately increased while reducing the water blowing phenomenon. When Δtc ≤ Δtc1, the temperature difference between the fin edge and the air outlet is small, and the rate of condensation is relatively low. The air conditioner's operating fan speed can be further increased to eliminate or mitigate the water blowing phenomenon while allowing the indoor ambient temperature to quickly approach the set target temperature, thus improving the user experience. Preferably, Δtc1 = 5℃ and Δtc2 = 7℃.

[0103] As an embodiment of the present invention, when the indoor environment is a medium-high humidity scenario, the preset outlet air temperature difference threshold includes a third preset outlet air temperature difference threshold △tc3 and a fourth preset outlet air temperature difference threshold △tc4, where △tc3 < △tc4. "Adjusting the upper limit of the air conditioner's fan speed operation based on the judgment result" includes:

[0104] When Δtc≤Δtc3, there is no limit to the upper limit of wind speed;

[0105] When △tc3<△tc<△tc4, adjust the upper limit of the air conditioner's fan speed to the high setting;

[0106] When △tc≥△tc4, adjust the upper limit of the air conditioner's fan speed to medium speed.

[0107] Where △tc3 and △tc4 are preset values, △tc3<△tc4, and △tc3<△tc1.

[0108] As an optional example, Δtc3 ranges from 2 to 4℃, and Δtc4 ranges from 6 to 8℃. With the above settings, when the indoor environment is of medium to high humidity and Δtc ≥ Δtc4, the temperature difference between the fin edge and the air outlet is relatively large. Although the condensation rate is reduced compared to high humidity scenarios, water blowing is still likely to occur. In this case, setting the air conditioner's fan speed to the medium setting can relatively improve cooling efficiency while eliminating or reducing water blowing. When Δtc3 < Δtc < Δtc4, the temperature difference between the fin edge and the air outlet decreases, and the upper limit of the fan speed can be appropriately increased to increase cooling capacity while eliminating or reducing water blowing. When Δtc ≤ Δtc3, the temperature difference between the fin edge and the air outlet is small, and the upper limit of the fan speed can be further increased or even eliminated to allow the indoor temperature to quickly approach the set target temperature while eliminating or reducing water blowing, thus improving the user experience. Preferably, Δtc3 = 3℃ and Δtc4 = 7℃. It should be noted that the relationship between Δtc2 and Δtc4 is not limited in this embodiment; they can be equal or unequal, and this is not further restricted. It should be understood that because the ambient humidity in a high-humidity scenario is higher than that in a medium-high humidity scenario, condensation occurs more rapidly. Therefore, in a high-humidity scenario, a lower upper limit for the airflow speed is needed compared to a medium-high humidity scenario to reduce the amount of condensation blown out, thereby eliminating or mitigating the water blowing effect. It should also be noted that when Δtc ≤ Δtc3, the probability of the air conditioner blowing water is extremely low. In this case, setting Δtc3 to be less than Δtc1 further reduces the temperature between the fin edge and the air outlet, further reducing the amount of condensation at the fin edge and lowering the probability of the air conditioner blowing water. In this case, the upper limit of the air conditioner's operating speed can be disregarded, ensuring the cooling effect while eliminating or mitigating the water blowing effect.

[0109] As an optional embodiment of the present invention, after each first preset time of operation in the anti-drip mode and / or anti-blowing mode, the indoor ambient humidity is re-detected, and the humidity range is determined. Based on the humidity range of the indoor environment, the corresponding anti-drip mode and / or anti-blowing mode is adjusted. It should be understood that after the air conditioner has been running for a period of time, the indoor humidity will continue to decrease due to the continuous condensation and discharge of moisture in the indoor environment. Since the operation of the anti-drip mode and / or anti-blowing mode has a certain impact on the cooling capacity of the air conditioner, readjusting the corresponding anti-drip mode and / or anti-blowing mode according to the change in indoor ambient humidity can eliminate or reduce dripping and condensation while improving the cooling effect of the air conditioner, thereby improving the user experience. The basis and method for adjusting the anti-drip mode and / or anti-blowing mode are the same as those for the aforementioned anti-drip mode and / or anti-blowing mode, and will not be repeated here. Optionally, the first preset time ranges from 2 to 4 minutes, preferably 3 minutes.

[0110] Furthermore, when the indoor environment is in a low-humidity scenario, the air conditioner operates normally without entering the anti-drip mode and / or anti-blowing mode. In low-humidity scenarios, there is no risk of dripping or blowing water from the air conditioner, and normal operation is sufficient to meet the user's needs, without the need for anti-drip or anti-blowing controls.

[0111] The above settings can effectively prevent large-scale condensation in the room caused by excessively rapid cooling in medium-to-high humidity scenarios, as well as water blowing and dripping from the air conditioner's vents, thus ensuring a good user experience while achieving indoor cooling.

[0112] Example 2

[0113] This embodiment discloses a heating defrosting control device, which is used to implement the anti-blowing and anti-dripping control method described in Embodiment 1.

[0114] The heating defrosting control device includes:

[0115] Humidity detection module, used to detect indoor humidity;

[0116] A temperature monitoring module is used to detect at least the indoor ambient temperature ta, and / or the fin edge temperature tp and the outlet air temperature tc;

[0117] The judgment module is at least used to determine the humidity range of the indoor environment.

[0118] The anti-drip module is used to activate the corresponding anti-drip mode according to the humidity range described in the indoor environment humidity, and / or the anti-blowing module is used to activate the corresponding anti-blowing mode according to the humidity range described in the indoor environment humidity.

[0119] Through the collaboration between the above modules, the rate of condensation during air conditioning cooling is controlled, avoiding large-scale condensation in the room and water blowing or dripping from the air conditioner's air outlet due to excessively rapid cooling. This ensures a good user experience while achieving indoor cooling.
