Description

Technical Field

[0001] This application relates to the field of air conditioner technology, such as a method, apparatus, air conditioner, and computer-readable storage medium for controlling an air conditioner. Background Technology

[0002] Currently, with the continuous improvement of living standards, air conditioners have become an indispensable household appliance in people's daily lives. When an air conditioner is running in cooling mode, the evaporator absorbs heat from the indoor air to cool it down. During this process, condensate is continuously produced, flowing down the evaporator into a drip tray below and being pumped out by a water pump. However, the drip tray, due to prolonged soaking, is prone to bacterial growth and dust accumulation, which can eventually lead to pump blockage, preventing timely drainage of condensate. This can cause condensate to overflow from the drip tray, resulting in problems such as dripping water from the ceiling, severely impacting the user experience. Based on this, a control method for an air conditioner has been proposed, including: receiving a blockage signal from a water level monitoring device in the drip tray indicating that the drain pipe of the drip tray is clogged; and controlling the air conditioner to stop operating when the blockage signal is received.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] While the relevant technologies can provide timely warnings when the air conditioner becomes clogged, directly shutting it off has a significant impact on the user's cooling experience and results in poor user comfort.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a method, apparatus, air conditioner, and computer-readable storage medium for controlling an air conditioner, which can prevent condensate from overflowing from the drip tray and also prevent poor user comfort caused by the air conditioner being turned off, thus helping to ensure the user's experience.

[0008] In some embodiments, the air conditioner includes an evaporator, and a water collection tray is provided below the evaporator to collect condensate generated by the evaporator. The water collection tray is provided with a drainage device and a detection device. The drainage device is used to drain the condensate in the water collection tray, and the detection device is used to detect the condensate level in the water collection tray. The method includes: increasing the suction superheat of the air conditioner when the condensate level is greater than or equal to a preset level; and adjusting the opening of the throttle valve of the air conditioner according to the increased suction superheat.

[0010] In some embodiments, the air conditioner includes: an evaporator; a drip tray disposed below the evaporator for receiving condensate generated by the evaporator; a drainage device disposed within the drip tray for draining the condensate from the drip tray; a detection device disposed within the drip tray for detecting the condensate level in the drip tray; and the aforementioned device for controlling the air conditioner is electrically connected to the detection device.

[0011] In some embodiments, the computer-readable storage medium stores program instructions that, when executed, cause the computer to perform the above-described method for controlling an air conditioner.

[0012] The method, apparatus, air conditioner, and computer-readable storage medium for controlling an air conditioner provided in this disclosure can achieve the following technical effects:

[0013] In this embodiment, the drainage device operates continuously during the cooling operation of the air conditioner to drain the condensate from the drip tray. When the condensate level is greater than or equal to a preset level, it indicates that the drainage device is not draining properly, and a certain degree of blockage may have occurred. Therefore, this embodiment increases the air intake superheat of the air conditioner and adaptively adjusts the opening of the air conditioner's expansion valve, thereby reducing the refrigerant flow rate of the system and thus reasonably reducing the cooling capacity of the air conditioner, which helps to reduce the generation of condensate.

[0028] Currently, with the continuous improvement of living standards, air conditioners have become an indispensable household appliance in people's daily lives. When an air conditioner is running in cooling mode, the evaporator absorbs heat from the indoor air to cool it down. During this process, condensate is continuously produced, flowing down the evaporator into a drip tray below and being pumped out by a water pump. However, the drip tray, due to prolonged soaking, is prone to bacterial growth and dust accumulation, which can eventually lead to pump blockage, preventing timely drainage of condensate. This can cause condensate to overflow from the drip tray, resulting in problems such as dripping water from the ceiling, severely impacting the user experience. Based on this, a control method for an air conditioner has been proposed, including: receiving a blockage signal from a water level monitoring device in the drip tray indicating that the drain pipe of the drip tray is clogged; and controlling the air conditioner to stop operating when the blockage signal is received.

[0029] While the relevant technologies can provide timely warnings when the air conditioner becomes clogged, directly shutting it off has a significant impact on the user's cooling experience and results in poor user comfort.

[0030] In this embodiment, the air conditioner includes an evaporator, a drip tray, a draining device, and a detection device. The drip tray, located below the evaporator, collects condensate produced by the evaporator. The draining device, located within the drip tray, drains the condensate from the tray. The detection device, located within the drip tray, detects the condensate level in the tray. Thus, as the air conditioner operates in cooling mode, the draining device continuously operates, thereby continuously draining the condensate from the drip tray.

[0031] Optionally, the drainage device includes a water pump and a drainage pipe. Thus, this embodiment of the present disclosure can continuously discharge condensate from the drip tray through the drainage pipe under the action of the water pump.

[0032] Optionally, the detection device is a float switch. This allows the system to sense the condensate level in the drip tray, facilitating timely activation of the appropriate controls.

[0033] Optionally, the detection device is a liquid level sensor. This allows for more accurate detection of the condensate level in the drip tray, facilitating timely activation of the corresponding controls.

[0034] Optionally, the air conditioner also includes a device for controlling the air conditioner, electrically connected to the detection device. Thus, embodiments of this disclosure can execute corresponding control methods through this device to reduce condensate generation when the condensate level is greater than or equal to a preset level, thereby preventing condensate overflow from the drip tray.

[0035] Combination Figure 1 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, comprising:

[0036] S101, when the condensate water level is greater than or equal to the preset water level, the processor increases the air intake superheat of the air conditioner.

[0037] S102, the processor adjusts the opening of the air conditioner's throttle valve based on the increased intake superheat.

[0038] The method for controlling an air conditioner provided in this disclosure involves a continuous drainage device that operates during the air conditioner's cooling cycle to drain condensate from the drip tray. When the condensate level is greater than or equal to a preset level, it indicates that the drainage device is not functioning properly, potentially indicating a blockage. Therefore, this disclosure increases the air intake superheat of the air conditioner and adaptively adjusts the opening of the throttle valve to reduce the refrigerant flow rate and thus reasonably reduce the air conditioner's cooling capacity, which helps reduce condensate formation. Consequently, this disclosure prevents condensate overflow from the drip tray and also avoids user discomfort caused by the air conditioner being turned off, thus ensuring a better user experience.

[0039] Optionally, the processor increases the air intake superheat of the air conditioner, including: the processor increases the air intake superheat of the air conditioner based on the duration for which the condensate water level is greater than or equal to a preset water level. Thus, this embodiment of the present disclosure obtains the duration for which the condensate water level is greater than or equal to the preset water level to determine the risk level of blockage in the drainage device. The longer the duration, the greater the risk of blockage in the drainage device, and the higher the possibility of condensate overflow from the drip tray. Therefore, this embodiment of the present disclosure appropriately increases the air intake superheat of the air conditioner based on this duration, thereby more reasonably reducing the refrigerant flow rate of the system, reducing condensate generation, and avoiding excessive fluctuations in cooling capacity that could cause user discomfort.

[0040] And / or,

[0041] Optionally, the processor increases the air intake superheat of the air conditioner, including: the processor increases the air intake superheat of the air conditioner based on the difference between the condensate water level and a preset water level. Thus, this embodiment of the present disclosure obtains the difference between the condensate water level and the preset water level to determine the degree of risk of blockage in the drainage device. The larger the water level difference, the greater the risk of blockage in the drainage device, and the higher the possibility of condensate overflow from the drip tray. Therefore, this embodiment of the present disclosure appropriately increases the air intake superheat of the air conditioner based on this water level difference, thereby more reasonably reducing the refrigerant flow rate of the system, reducing condensate generation, and avoiding excessive fluctuations in cooling capacity that could cause user discomfort.

[0042] Optionally, the processor increases the air intake superheat of the air conditioner based on the duration for which the condensate water level is greater than or equal to a preset water level, including: the processor calculating SH A =SH0+(t1 / t) max )×SH P1 The processor obtains a first target value for the suction superheat; the processor increases the suction superheat of the air conditioner to the first target value. Among them, SH A SH0 is the initial value of the suction superheat, t1 is the duration for which the condensate water level is greater than or equal to the preset water level, and t is the first target value of the suction superheat. max For duration threshold, SH P1 This is the first compensation value for the suction superheat. Thus, this embodiment calculates the first target value after the suction superheat increases using the above formula, and can reasonably limit the compensation amount for the suction superheat based on the ratio of the duration during which the condensate level is greater than or equal to a preset level to a duration threshold. This allows for a more reasonable reduction in the system's refrigerant flow rate, reducing condensate generation while also preventing excessive fluctuations in cooling capacity that could cause user discomfort.

[0043] Optionally, the duration threshold t max This can be obtained through experimental testing. Specifically, it involves setting a threshold t for the duration during which the air conditioner operates continuously at its rated power for cooling. max The duration of continuous operation of the drainage device to drain the water tray from full to empty. Preferably, the duration threshold t. max It can be set to 40 seconds to determine if the drainage device is severely clogged. Duration threshold t max It can also be adjusted according to the user's actual needs, and can be set to any other reasonable value such as 30s or 60s.

[0044] Optionally, the first compensation value SH for intake superheat. P1 It can be set according to indoor environmental parameters. Specifically, when the indoor ambient temperature is less than or equal to the preset temperature, a relatively comfortable low-temperature environment has been created indoors, so a relatively large first compensation value SH can be set. P11 This reduces the cooling capacity of the air conditioner, which helps reduce condensation. When the indoor ambient temperature is higher than the preset temperature, a relatively small first compensation value SH can be set. P12 This ensures that condensate does not overflow from the drip tray while also providing a good cooling experience for the user. The indoor environmental parameter can also be the indoor humidity; refer to the corresponding process in other embodiments, which will not be repeated here. Preferably, the first compensation value SH for the suction superheat is... P1 It can be set to 10℃ to reasonably limit the compensation amount for intake superheat. The first compensation value for intake superheat is SH. P1It can also be adjusted according to the user's actual needs, or set to any other reasonable value such as 5℃ or 12℃.

[0045] Optionally, the processor increases the air intake superheat of the air conditioner based on the difference between the condensate water level and the preset water level, including: the processor calculates the SH... B =SH0+(h1 / h max )×SH P2 The processor obtains a second target value for the suction superheat; the processor increases the suction superheat of the air conditioner to the second target value. Among them, SH B Here, SH0 is the initial value of the suction superheat, h1 is the difference between the condensate water level and the preset water level, and h is the second target value of the suction superheat. max SH is the threshold value for water level difference. P2 This is the second compensation value for the suction superheat. Thus, this embodiment calculates the second target value after the suction superheat is increased using the above formula, and can reasonably limit the compensation amount for the suction superheat based on the ratio of the difference between the condensate water level and the preset water level to a water level difference threshold. This allows for a more reasonable reduction in the system's refrigerant flow rate, reducing condensate generation while also preventing excessive fluctuations in cooling capacity that could cause user discomfort.

[0046] Optionally, the water level difference threshold h max This can be set according to the configuration parameters of the water receiving tray. Specifically, the water level difference threshold h max This can be the difference between the total water level in the receiving tray and the preset water level. Preferably, the water level difference threshold h... max The threshold value can be set to 5cm to determine if the drainage device is severely clogged. Water level difference threshold h max It can also be adjusted according to the user's actual needs, and can be set to any other reasonable value such as 4cm or 6cm.

[0047] Optionally, the second compensation value SH for intake superheat. P2 It can be set according to indoor environmental parameters. Specifically, when the indoor humidity is greater than or equal to the preset humidity, condensation is likely to occur, resulting in more condensate. Therefore, a relatively large second compensation value SH can be set. P21 This reduces the air conditioner's cooling capacity, which helps balance the amount of condensate generated. When the indoor humidity is lower than the preset humidity, a relatively small second compensation value SH can be set. P22 This ensures that condensate in the drip tray does not overflow while also providing a good cooling experience for the user. The indoor environmental parameter can also be the indoor ambient temperature; refer to the corresponding process in other embodiments, which will not be repeated here. Preferably, the second compensation value SH for the suction superheat... P2It can be set to 10℃ to reasonably limit the compensation amount for intake superheat. The second compensation value for intake superheat, SH. P2 It can also be adjusted according to the user's actual needs, or set to any other reasonable value such as 5℃ or 12℃.

[0048] Optionally, the processor can periodically increase the intake superheat of the air conditioner. In this way, embodiments of the present disclosure can repeatedly execute the aforementioned steps at preset time intervals, thereby gradually increasing the intake superheat of the air conditioner to avoid excessively rapid adjustments that could affect the stability of the air conditioner's operation.

[0049] Optionally, the processor adjusts the throttle valve opening of the air conditioner according to the increased suction superheat, including: the processor adjusts the throttle valve opening of the air conditioner according to a PID (Proportional Integral Derivative) algorithm to stabilize the increased suction superheat. Thus, this embodiment of the present disclosure can achieve precise adjustment of the throttle valve opening, allowing the suction superheat of the air conditioner to gradually stabilize near the increased target value.

[0050] Combination Figure 2 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0051] S201, when the condensate water level is greater than or equal to the preset water level, the processor increases the air intake superheat of the air conditioner.

[0052] S202, the processor adjusts the opening of the air conditioner's throttle valve based on the increased intake superheat.

[0053] S203, when the condensate water level meets the preset dirt blockage conditions, the processor restricts the opening of the air conditioner's throttle valve.

[0054] The method for controlling an air conditioner provided in this disclosure involves a continuous drainage device that operates during the air conditioner's cooling cycle to drain condensate from the drip tray. When the condensate level is greater than or equal to a preset level, it indicates poor drainage, suggesting possible blockage. Therefore, this disclosure increases the air intake superheat of the air conditioner and adaptively adjusts the opening of the throttle valve to reduce the refrigerant flow rate and thus reasonably reduce the air conditioner's cooling capacity, which helps reduce condensate formation. Furthermore, when the condensate level meets a preset blockage condition, it indicates severe blockage of the drainage device. Therefore, this disclosure further restricts the opening of the throttle valve to ensure the refrigerant flow rate is not excessive, thereby further suppressing condensate formation. Thus, this disclosure prevents condensate overflow from the drip tray and avoids user discomfort when the air conditioner is turned off, ensuring a better user experience.

[0055] Optionally, the preset clogging condition includes: the condensate water level being greater than or equal to a preset water level for a duration greater than or equal to a threshold duration. Thus, when this duration is greater than or equal to the threshold duration, it indicates that the drain device is severely clogged, and the condensate in the drip tray cannot be effectively drained within a short time. Therefore, it is determined that the preset clogging condition is met, and the air conditioner performs further control to further suppress condensate formation, thereby helping to prevent condensate overflow from the drip tray.

[0056] And / or,

[0057] Optionally, the preset clogging condition includes: the difference between the condensate water level and a preset water level is greater than or equal to a water level difference threshold. When this water level difference is greater than or equal to the threshold, it indicates that the drainage device is severely clogged, and the condensate water level in the drip tray is still rising or even about to overflow. Therefore, it is determined that the preset clogging condition is met, and the air conditioner performs further control to further suppress condensate formation, thereby helping to prevent condensate overflow from the drip tray.

[0058] Optionally, the processor limits the opening of the air conditioner's throttle valve by controlling the throttle valve opening to be less than or equal to a preset limit. Thus, when the preset clogging condition is met, this embodiment of the invention controls the air conditioner's throttle valve opening to always be less than the preset limit, thereby ensuring that the refrigerant flow rate of the system is not excessive, thus further suppressing the generation of condensate. Therefore, this embodiment of the invention can better prevent condensate overflow from the drip tray.

[0059] Combination Figure 3 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0060] S301, when the condensate water level is greater than or equal to the preset water level, the processor increases the air intake superheat of the air conditioner.

[0061] S302, the processor adjusts the opening of the air conditioner's throttle valve based on the increased intake superheat.

[0062] S303: When the condensate water level meets the preset dirt blockage conditions, the processor restricts the opening of the air conditioner's throttle valve.

[0063] S304, the processor reduces the operating frequency of the air conditioner's compressor. And / or,

[0064] S305, the processor increases the speed of the air conditioner's indoor fan.

[0065] The method for controlling an air conditioner provided in this disclosure involves a continuous drainage device that operates during the air conditioner's cooling cycle to drain condensate from the drip tray. When the condensate level is greater than or equal to a preset level, it indicates poor drainage, suggesting possible blockage. Therefore, this disclosure increases the air intake superheat of the air conditioner and adaptively adjusts the opening of the throttle valve to reduce the refrigerant flow rate and thus reasonably reduce the air conditioner's cooling capacity, which helps reduce condensate formation. Furthermore, when the condensate level meets a preset blockage condition, it indicates severe blockage of the drainage device. Therefore, this disclosure further limits the opening of the throttle valve to ensure the refrigerant flow rate is not excessive, further suppressing condensate formation. Additionally, this disclosure reduces the compressor's operating frequency, which reduces refrigerant supply and also suppresses condensate formation. Finally, this disclosure increases the speed of the air conditioner's indoor fan to promote condensate evaporation and reduce the amount of condensate entering the drip tray. Therefore, the embodiments disclosed herein can prevent condensate from overflowing from the drip tray, and can also prevent poor user comfort caused by the air conditioner being turned off, thus helping to ensure the user's experience.

[0066] Optionally, the processor reduces the compressor operating frequency of the air conditioner by: determining a target reduction value for the compressor operating frequency based on indoor environmental parameters; and reducing the compressor operating frequency of the air conditioner according to the target reduction value. The indoor environmental parameters include indoor temperature and / or indoor humidity. Thus, this embodiment of the present disclosure can reasonably limit the target reduction value of the compressor operating frequency based on indoor environmental information, thereby more reasonably reducing the compressor operating frequency of the air conditioner to avoid over-adjustment affecting the user's cooling experience.

[0067] Optionally, the processor increases the indoor fan speed of the air conditioner by: determining a target increase value for the indoor fan speed based on indoor environmental parameters; and increasing the indoor fan speed of the air conditioner according to the target increase value. The indoor environmental parameters include indoor ambient temperature and / or indoor ambient humidity. Thus, this embodiment of the present disclosure can reasonably limit the target increase value of the indoor fan speed based on indoor environmental information, thereby more reasonably increasing the indoor fan speed of the air conditioner to avoid over-adjustment affecting the user's cooling experience.

[0068] Combination Figure 4 As shown in the embodiments of this disclosure, another method for controlling an air conditioner is provided, including:

[0069] S401, when the condensate water level is greater than or equal to the preset water level, the processor increases the air intake superheat of the air conditioner.

[0070] S402, the processor adjusts the opening of the air conditioner's throttle valve based on the increased intake superheat.

[0071] S403, when the condensate water level meets the preset dirt blockage conditions, the processor restricts the opening of the air conditioner's throttle valve.

[0072] S404, the processor sends a cleaning prompt message.

[0073] The method for controlling an air conditioner provided in this disclosure involves a continuous drainage device that operates during the air conditioner's cooling cycle to drain condensate from the drip tray. When the condensate level is greater than or equal to a preset level, it indicates poor drainage, suggesting possible blockage. Therefore, this disclosure increases the air intake superheat of the air conditioner and adaptively adjusts the opening of the throttle valve to reduce the refrigerant flow and thus reduce the air conditioner's cooling capacity, thereby minimizing condensate formation. Furthermore, when the condensate level meets a preset blockage condition, it indicates severe blockage of the drainage device. Therefore, this disclosure further restricts the opening of the throttle valve to ensure the refrigerant flow is not excessive, further suppressing condensate formation. Additionally, this disclosure sends cleaning reminders to remind users to clean the drainage device after use, promoting normal cooling operation. Thus, this disclosure prevents condensate overflow from the drip tray and avoids user discomfort when the air conditioner is turned off, ensuring a better user experience.
