Description

Technical Field

[0001] This invention relates to the field of intelligent device technology, and in particular to a control method, apparatus, electronic device, and storage medium for device self-cleaning. Background Technology

[0002] With the acceleration of modern urbanization, the installation location and conditions of air conditioners, as an important household appliance, are facing increasing restrictions. Especially in some high-end residential communities or apartments, in order to maintain the aesthetics and uniformity of the building's appearance, the installation location of air conditioner outdoor units is often designed in enclosed or semi-enclosed spaces.

[0003] In related technologies, air conditioner self-cleaning is initiated by detecting the air conditioner's running time; that is, the self-cleaning function starts after the set running time is reached. However, because air conditioners installed in enclosed spaces have obstructed exhaust and intake air, the hot air that cannot be exhausted flows back to the air intake. This causes dust and contaminants carried by the hot air to easily accumulate on the condenser, leading to more frequent blockages. Therefore, in reality, even before the set running time is reached, the condenser surface is already covered with dust and contaminants, resulting in reduced heat exchange efficiency, incomplete refrigerant liquefaction, and consequently, affecting the air conditioner's cooling performance.

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] Figure 1 This is a flowchart illustrating the steps of a self-cleaning control method for equipment provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the method may include:

[0063] Step 101: Obtain the startup dirt and blockage coefficient and startup ambient temperature of the target device.

[0064] In this embodiment of the invention, the target device can be an air conditioner or other device with a self-cleaning function. After the target device is turned on, the ambient temperature of the outdoor unit is obtained by an ambient temperature sensor installed at the outdoor unit of the air conditioner, which is used as the start-up ambient temperature. The ambient temperature sensor is used to detect the ambient temperature around the outdoor unit of the air conditioner in real time. The start-up dirt-clogging coefficient corresponding to the target device is obtained. The start-up dirt-clogging coefficient characterizes the degree of dirt-clogging of the outdoor unit condenser when the target device is turned on. Based on the start-up dirt-clogging coefficient, it can be determined whether the target device needs to perform outdoor unit self-cleaning. The larger the start-up dirt-clogging coefficient, the more severe the dirt-clogging of the outdoor unit condenser. The start-up dirt-clogging coefficient can be determined based on the cumulative running time of the target device. Alternatively, since dirt-clogging of the outdoor unit condenser leads to increased wind resistance and reduced outdoor motor power, the degree of dirt-clogging can also be determined by comparing the difference between the real-time power and the standard power of the outdoor motor. It is understood that the start-up dirt-clogging coefficient can be determined based on other parameters related to the degree of condenser dirt-clogging, and this embodiment of the invention does not limit the method of determining the start-up dirt-clogging coefficient.

[0065] Optionally, step 101 may include the following steps:

[0066] Step 1011: Obtain the cumulative running time of the target device; the cumulative running time is determined based on the historical running modes of the target device and the equivalent coefficients corresponding to different running modes.

[0067] In this embodiment of the invention, the cumulative running time of the target device is obtained. The cumulative running time is determined based on the target device's historical operating modes and preset equivalent coefficients corresponding to different operating modes. For example, the target device's historical operating modes and the actual running time corresponding to each historical operating mode can be obtained. For any historical operating mode, the actual running time corresponding to that historical operating mode is multiplied by the equivalent coefficient corresponding to that historical operating mode to obtain the equivalent running time corresponding to that historical operating mode. The equivalent running times corresponding to each historical operating mode are then added together to obtain the cumulative running time. It is understood that in practical scenarios, the cumulative running time recorded by the target device can be updated based on the running time corresponding to the current operating mode and the equivalent coefficient after each time the target device stops running.

[0068] When the target equipment is in different operating modes, the airflow through the outdoor unit condenser varies, and consequently, the degree of dust and contaminant accumulation on the condenser also differs. For example, compared to operating in a low-fan mode, operating the target equipment in a high-fan mode will result in more severe dust and contaminant accumulation on the condenser. Therefore, it is necessary to perform equivalent processing on the running time of different operating modes in order to determine a more accurate dirt and clogging coefficient based on the running time.

[0069] Equivalent coefficients are pre-set for different operating modes. Specifically, one operating mode can be selected as the base operating mode, and equivalent coefficients are set for other operating modes based on this base mode. For example, assuming the base operating mode is set to high windshield mode, the corresponding equivalent coefficient is 1, the equivalent coefficient for medium windshield mode is 0.8, and the equivalent coefficient for low windshield mode is 0.6. Then, if the target device operates for 1 hour in medium windshield mode, it is equivalent to operating for 1 hour × 0.8 = 0.8 hours in high windshield mode.

[0070] Step 1012: Based on the cumulative running time and the second correspondence, obtain the startup dirt and blockage coefficient.

[0071] In this embodiment of the invention, as the fan's operating time increases, the condenser's fouling and blockage become more severe. Simultaneously, as the fouling and blockage worsens, the condenser's ventilation area gradually decreases, thus accelerating the fouling and blockage process. Therefore, as the operating time increases, the rate of increase in the fouling and blockage coefficient also gradually increases. Thus, the start-up fouling and blockage coefficient can be obtained based on the cumulative operating time and a predetermined second correspondence between operating time and the fouling and blockage coefficient. The second correspondence is the relationship between operating time and the fouling and blockage coefficient. For example, the cumulative operating time t... 等效 The second correspondence with the dirt and clogging coefficient K can be as follows: Figure 2As shown, with the increase in the cumulative operating time of the outdoor unit fan, the degree of dirt and clogging of the outdoor unit condenser also increases, meaning the dirt and clogging coefficient continuously increases. Furthermore, as the outdoor unit becomes dirt and clogging, the condenser ventilation area decreases, which accelerates the rate of dirt and clogging, ultimately leading to... Figure 2 The curve shows the situation. It's understandable that the cumulative running time t... 等效 The second correspondence between the fouling coefficient K and the outdoor unit can be a functional relationship or a one-to-one correspondence through a mapping table. It is understandable that the fouling rate is related to the outdoor unit's structure, condenser, and outdoor unit motor parameters, which can be determined through experimental measurements.

[0072] It is understandable that the dirt and blockage coefficient at the moment the target device is powered on corresponds to the cumulative running time of the target device. The cumulative running time recorded by the system is different each time the device is powered on, so the value of the dirt and blockage coefficient is also different each time the device is powered on.

[0073] In this embodiment of the invention, the cumulative operating time is determined based on the historical operating modes of the target device and the equivalent coefficients corresponding to different operating modes. According to the different characteristics of the impact of different operating modes on the degree of condenser clogging, the operating time of the target device can be calculated by equivalent calculation, so that the degree of condenser clogging represented by the start-up clogging coefficient determined based on the cumulative operating time can be more realistic.

[0074] Step 102: Based on the target temperature difference between the start-up ambient temperature and the stable equipment temperature, the start-up dirt and clogging coefficient is corrected to obtain the target dirt and clogging coefficient; the stable equipment temperature is the temperature corresponding to the target equipment in a stable operating state.

[0075] In this embodiment of the invention, when the target equipment is operating stably, the stable temperature of the equipment is determined based on the temperature detected by the ambient temperature sensor. The stable temperature can be the ambient temperature of the outdoor unit of the target equipment when the target equipment is operating smoothly, i.e., when all parameters of the target equipment tend to stabilize. The difference between the start-up ambient temperature and the stable temperature of the equipment is obtained as the target temperature difference. Based on the target temperature difference, the start-up fouling coefficient is corrected to obtain the target fouling coefficient. The target fouling coefficient characterizes the actual degree of fouling in the condenser of the target equipment. The principle of correcting the start-up fouling coefficient based on the target temperature difference is that the more enclosed the outdoor unit location, the worse the airflow, and the greater the difference in outer ring temperature rise before and after the outdoor unit is started, i.e., the target temperature difference. For example, if the outdoor unit is installed in an open location with no obstructions to the air inlet and outlet, the air intake of the outdoor unit is smooth, and the temperature detected by the outer ring temperature sensor is the actual temperature of the outer ring. While the condenser temperature rises after the outdoor unit in an open mounting location is turned on, and the heat radiation it emits will cause the temperature detected by the outer ring temperature sensor to rise, the change is relatively small. However, if the outdoor unit is installed in a closed mounting location, enclosed on three sides and with louvers blocking the front, before startup, due to natural convection heat transfer, the temperature inside the closed mounting location is close to the ambient temperature outside. This means the startup ambient temperature for the target equipment is close to the actual ambient temperature. After startup, the airflow from the air conditioner is blocked by the louvers, causing the air from the outdoor unit to flow back to the air inlet. The air inside the closed mounting location is continuously heated by the outdoor unit, leading to an increase in the detected outer ring temperature within the closed mounting location. Thus, the target temperature difference for the same equipment will differ depending on the outdoor unit's mounting configuration. Since the target temperature difference characterizes the degree of enclosure of the target equipment's outdoor unit installation, a higher target temperature difference indicates a higher degree of enclosure, and consequently, a higher degree of condenser blockage during operation. In actual installation, the size of the enclosed mounting location and the louver gaps also vary, affecting the degree of heat dissipation of the outdoor unit to different extents. Therefore, the fouling coefficient can be corrected to different degrees for different levels of enclosure, meaning that different target temperature differences correspond to different fouling coefficient correction values. For example, such as... Figure 2 As shown, t 下限 This can characterize the lower limit of the cumulative operating time when the target device needs to perform self-cleaning; correspondingly, K 下限 This can characterize the lower limit of the dirt clogging coefficient when the target device needs to perform self-cleaning, i.e., the preset threshold. This threshold is set when the target dirt clogging coefficient is greater than or equal to K. 下限 At this time, the target device needs to perform self-cleaning.

[0076] Optionally, step 102 may include the following steps:

[0077] Step 1021: When the target device enters the operating state, obtain the real-time temperature corresponding to the target device.

[0078] In this embodiment of the invention, after the target device is powered on and enters the running state, the real-time temperature of the target device is obtained based on the temperature detected by the ambient temperature sensor.

[0079] Step 1022: Determine the temperature change value based on the first real-time temperature corresponding to any first time and the second real-time temperature corresponding to a second time before the first time and with a time interval of a preset duration from the first time.

[0080] In this embodiment of the invention, the condition for determining that the target device is in a stable operating state may include that the real-time temperature change value is less than a preset change value within a preset time period. Then, using the preset time period as the judgment cycle, the first real-time temperature corresponding to any first time point and the second real-time temperature corresponding to a second time point preceding the first time point and with a time interval of the preset time period are obtained. Based on the first and second real-time temperatures, the temperature change value is determined. The target time period can be set according to requirements, for example, 1 minute. The temperature change value is used to characterize the change in the real-time temperature of the indoor and outdoor units within the preset time period from the first time point to the second time point. For example, assuming the first time point is the Nth second after the target device is powered on, then the second time point is the N-60th second after the target device is powered on, and correspondingly, the first real-time temperature is T. N The second real-time temperature is T. N-60 The temperature change value is T. N -T N-60 .

[0081] Step 1023: If the temperature change value is less than or equal to the preset change value, the first real-time temperature is determined as the stable temperature of the device.

[0082] In this embodiment of the invention, if the temperature change is less than or equal to a preset change value, the target device is determined to be in a stable operating state, and the first real-time temperature is determined as the stable temperature of the device. If the temperature change is greater than the preset change value, based on the next preset time period, it is determined whether the temperature change is less than or equal to the preset change value, until the target device is in a stable operating state.

[0083] For example, the outdoor temperature before power-on is 35℃, meaning the ambient temperature at power-on is 35℃. After power-on, the outdoor unit dissipates heat, and the ambient temperature gradually rises from 35℃ to 48℃. Within a preset time period of 1 minute, the second real-time temperature corresponding to the start time is 47.5℃, and the first real-time temperature corresponding to the end time is 48℃. If the temperature change of 0.5℃ is less than the preset change value of 1℃ (meaning the outdoor ambient temperature remains stable at 48±1℃ within this 1 minute), then the system is considered stable, the target device is in a stable operating state, and the stable temperature of the device is recorded as 48℃.

[0084] In this embodiment of the invention, by determining whether the temperature change value corresponding to different time periods within a preset time period is less than or equal to a preset change value, it is determined whether the target device is in a stable operating state, and thus the stable temperature of the device is obtained. This allows for a quick and accurate determination of the operating state of the target device, thereby improving the accuracy of the stable temperature of the device and laying the foundation for accurately correcting the start-up dirt and blockage coefficient.

[0085] Step 103: When the target dirt and clogging coefficient is greater than or equal to a preset threshold, control the target device to perform a self-cleaning operation.

[0086] In this embodiment of the invention, the degree of clogging of the target device is determined based on the corrected target clogging coefficient, confirming whether the target device requires self-cleaning. If the target clogging coefficient is greater than or equal to a preset threshold, indicating that the condenser of the target device is clogging to the point where self-cleaning is required, the target device is controlled to perform a self-cleaning operation. The preset threshold can be set according to actual needs; for example, the clogging coefficient corresponding to when the target device needs self-cleaning can be determined as the preset threshold. This embodiment of the invention does not limit the value of the preset threshold. For example, the user can be reminded via the indoor unit panel or application software that the outdoor unit needs self-cleaning, or the target device can automatically initiate the self-cleaning operation.

[0087] In summary, in this embodiment of the invention, the startup dirt and clogging coefficient and startup ambient temperature of the target device are obtained; the startup dirt and clogging coefficient is corrected based on the target temperature difference between the startup ambient temperature and the stable temperature of the device to obtain the target dirt and clogging coefficient; the stable temperature of the device is the temperature corresponding to the target device in a stable operating state; when the target dirt and clogging coefficient is greater than or equal to a preset threshold, the target device is controlled to perform a self-cleaning operation. In this way, with the target equipment in the powered-on state, the startup dirt-clogging coefficient of the target equipment is first obtained. Then, based on the temperature difference between the startup ambient temperature and the target stable temperature of the equipment, the startup dirt-clogging coefficient is corrected to obtain the target dirt-clogging coefficient. The target dirt-clogging coefficient is used as the criterion for judging whether the target equipment needs to be self-cleaned. Based on the target dirt-clogging coefficient, the degree of dirt-clogging of the target equipment's condenser can be more accurately characterized, thus allowing for a more timely and accurate determination of when the target equipment needs to be self-cleaned. Compared to judging whether the target equipment needs to be self-cleaned based solely on the target equipment's operating time, this method can accurately and timely perform self-cleaning regardless of the target equipment's placement environment. This avoids the decrease in heat exchange efficiency and the inability of refrigerant to fully liquefy due to condenser dirt-clogging, ensuring the heat exchange efficiency and refrigerant liquefaction effect of the target equipment, and thus improving the cooling effect of the air conditioner to a certain extent.

[0088] Optionally, step 102 may include the following steps:

[0089] Step 201: Obtain the target temperature difference between the ambient temperature at startup and the stable temperature of the device.

[0090] Step 202: Based on the target temperature difference and the first correspondence, determine the target correction value corresponding to the target temperature difference.

[0091] In this embodiment of the invention, when the target device is in a stable operating state, the stable temperature of the device is acquired, and the difference between the stable temperature of the device and the ambient temperature at startup is calculated to obtain the target temperature difference. Based on the target temperature difference and a first correspondence, a temperature correction value corresponding to the target temperature difference is determined. The first correspondence is the relationship between the temperature difference and the temperature correction value.

[0092] Optionally, step 202 may include the following steps:

[0093] Step 2021: If the target temperature difference is less than the first temperature, determine the target correction value as the first correction value.

[0094] Step 2022: If the target temperature difference is greater than or equal to the first temperature and less than the second temperature, determine the target correction value based on the target positive correlation coefficient.

[0095] Step 2023: If the target temperature value is greater than or equal to the second temperature, determine the target correction value as the second correction value.

[0096] In this embodiment of the invention, since the degree of enclosure of the outdoor unit environment where the target device is located will affect the condenser's dirt blockage to varying degrees, the dirt blockage coefficient can be modified to different degrees for different degrees of enclosure based on the target temperature difference that can characterize the degree of enclosure of the outdoor unit environment, so that the dirt blockage coefficient is more consistent with the actual degree of dirt blockage. Specifically, based on the correlation between temperature difference and condenser blockage in actual scenarios, the temperature difference can be divided into three intervals. When the target temperature difference is less than the first temperature, the impact of the condenser blockage on the degree of enclosure of the outdoor unit environment is relatively small, and the correction value can be 0. When the target temperature difference is greater than or equal to the first temperature and less than the second temperature, the condenser blockage is positively correlated with the degree of enclosure of the outdoor unit environment. Accordingly, the correction value will increase as the target temperature difference increases. That is, the larger the target temperature difference, the higher the degree of enclosure of the outdoor unit environment, and the more serious the condenser blockage, the larger the correction value will be to make the target blockage coefficient more consistent with the actual blockage situation. When the target temperature difference exceeds a certain upper limit, according to the operating characteristics of the target equipment, the impact on the condenser blockage will not change significantly with the degree of enclosure of the outdoor unit environment. Therefore, when the target temperature difference is greater than the second temperature, the correction value will tend to be the same value. Based on this, when the target temperature difference is less than a first temperature, the target correction value is determined as a first correction value; when the target temperature difference is greater than or equal to the first temperature and less than a second temperature, the target correction value is determined based on a preset target positive correlation coefficient between the temperature difference and the correction value; when the target temperature is greater than or equal to the second temperature, the target correction value is determined as a second correction value. The target positive correlation coefficient is determined based on the correspondence between the temperature difference and the correction value when the temperature difference is within the first and second temperature ranges. When the temperature difference is within the first and second temperature ranges, the temperature difference and the correction value are positively correlated, meaning the larger the temperature difference, the larger the correction value. Based on the positive correlation between the temperature difference and the correction value, the target positive correlation coefficient can be determined. The first temperature, the second temperature, the first correction value, the second correction value, and the target positive correlation coefficient can be set according to actual needs or determined through experimental testing; this embodiment of the invention does not impose any limitations on this.

[0097] It is understandable that the first correspondence can be a function or a preset numerical table. The first correspondence is related to the different outdoor unit types and their outdoor unit structural parameters of the target device, and can be obtained by testing according to the actual scenario.

[0098] For example, the temperature difference T 温差 The first correspondence with the temperature correction value C can be as follows: Figure 3 As shown, where C and T 温差 The correspondence is divided into three intervals. First interval: T 温差 <T温差下限 The outdoor unit is not affected by the enclosed location or is only minimally affected, C=0, meaning it has no actual corrective effect on the dirt / clogging coefficient K; Second interval: T 温差下限 ≤T 温差 ≤T 温差上限 With T 温差 The greater the improvement, the greater the impact of heat dissipation on the outdoor unit, the larger the temperature correction value C, and the greater the correction to the dirt clogging coefficient K; Third interval: T 温差 >T 温差上限 C = C 上限 The correction effect on the dirt-clogging coefficient K value is also maximized. To avoid over-correction of the C value, which would lead to excessively frequent self-cleaning and affect the user experience, subsequent adjustments were made with T... 温差 As the value increases, the value of C no longer increases and remains constant at C. 上限 .

[0099] In this embodiment of the invention, by determining the target correction value based on the correspondence between the target temperature difference and the degree of condenser clogging when the target device operates in a closed space with different degrees of enclosure, the target device can adapt to different placement environments. Under the premise of ensuring that the target device can perform self-cleaning in a timely manner, the adaptability and flexibility of the target device deployment environment are improved.

[0100] Step 203: Determine the target dirt and blockage coefficient based on the startup dirt and blockage coefficient and the target correction value.

[0101] In this embodiment of the invention, a target contamination coefficient is determined based on the startup contamination coefficient and a target correction value. Specifically, the startup contamination coefficient can be added to the target correction value to obtain the target contamination coefficient. For example, assume the startup contamination coefficient is K. 开机 If the target correction value is C, then the target clogging coefficient K = K 开机 +C.

[0102] In this embodiment of the invention, by obtaining the target correction value based on the target temperature difference, the dirt-clogging coefficient can be adjusted to eliminate or reduce the error caused by the placement environment of the target equipment outdoor unit with different degrees of sealing, thereby improving the accuracy of the target dirt-clogging coefficient. This allows the target dirt-clogging coefficient to more realistically characterize the dirt-clogging situation of the condenser, thus facilitating timely self-cleaning of the equipment based on the dirt-clogging situation.

[0103] Optionally, embodiments of the present invention may further include the following steps:

[0104] Step 301: If the target device stops operating when the target clogging coefficient is less than the preset threshold, update the cumulative operating time based on the current operating time of the target device and the target operating mode of the target device.

[0105] In this embodiment of the invention, when the target clogging coefficient is less than a preset threshold, it indicates that the degree of condenser clogging has not yet reached the level requiring self-cleaning. Therefore, during this operation, the target device may not be self-cleaned. After the target device stops operating, that is, after the target device ends this operation, the cumulative operating time is updated based on the current operating time of the target device and the target operating mode adopted by the target device in this operation.

[0106] For example, assuming the target equipment is first turned on and the outdoor unit runs at high fan speed for 100 hours, the equivalent operating time for this operation is 100 hours. The second time it is turned on, the outdoor fan runs at high fan speed for 80 hours and at medium fan speed for 20 hours. Therefore, the equivalent operating time for this operation = high fan speed operating time + medium fan speed operating time × the equivalent coefficient corresponding to medium fan speed operation mode = 80 + 20 * 0.8 = 96 hours. Correspondingly, if the equipment only underwent these two turn-on processes, the cumulative operating time of the fan = first equivalent operating time + second equivalent operating time = 100 + 96 = 196 hours.

[0107] In this embodiment of the invention, when the target dirt and clogging coefficient is less than a preset threshold, the cumulative running time will be updated based on the running time and running mode after the current operation ends. Through equivalent calculation, the time can be accurately calculated according to the characteristics of different running modes, thereby more accurately reflecting the actual running time of the target device.

[0108] Optionally, after step 103, embodiments of the present invention may include the following steps:

[0109] Step 401: Set the cumulative running time of the target device as the initial running time.

[0110] In this embodiment of the invention, after the target device initiates self-cleaning, it is assumed that the outdoor unit of the target device has been cleared of dirt and clogging. Therefore, the cumulative running time, dirt and clogging coefficient, and related correction parameters of the target device can be initialized. This includes setting the cumulative running time of the target device as the initial running time, the dirt and clogging coefficient as the initial coefficient, and the related correction parameters as initial values. For example, the cumulative running time, dirt and clogging coefficient, and related correction parameters of the target device can be reset to zero, i.e., the dirt and clogging coefficient K = 0, the related correction parameter C = 0, and the cumulative running time t of the target device... 等效 =0.

[0111] In this embodiment of the invention, after the target device performs self-cleaning, the cumulative running time of the target device is reset so that the target device can determine the next self-cleaning cycle.

[0112] For example, suppose the preset threshold is 10, meaning that when the target dirt-clogging coefficient is greater than or equal to 10, the target device is controlled to perform self-cleaning. According to... Figure 2 It can be determined that when the cumulative operating time of the target equipment is 3600 hours, the corresponding start-up dirt-clogging coefficient K is 10; when the cumulative operating time is 3000 hours, the corresponding start-up dirt-clogging coefficient K is 8; and when the cumulative operating time is 2200 hours, the corresponding start-up dirt-clogging coefficient K is 6. And it is assumed that... Figure 3 T in 温差下限 =5℃, T 温差上限 =25℃, C 上限 =4, that is, when T 温差 ≥T 温差上限 At 25℃, the correction value C for the dirt clogging coefficient reaches its maximum value. 上限 And is always equal to C 上限 .

[0113] Based on the above conditions, and depending on the degree of enclosure of the outdoor unit location, the operating conditions can be as follows:

[0114] 1. When the outdoor unit is in an open, unobstructed or slightly enclosed location, the target temperature difference T after startup. 温差 If the temperature is <5℃, the target correction value C = 0, and no actual correction effect is produced. That is, when the cumulative operating time of the target equipment meets 3600 hours, the start-up dirt-clogging coefficient K... 开机 If the value is 10, then the target dirt and clogging coefficient K = K 开机 +C=10+0=10, which equals the preset threshold of 10, satisfying the self-cleaning condition, and controlling the target device to perform self-cleaning.

[0115] 2. Under moderate enclosure conditions of the outdoor unit, the target temperature difference T after startup. 温差 =15℃, then the target correction value C=2, that is, when the cumulative operating time of the target equipment meets 3000h, the start-up dirt blockage coefficient K 开机 The corrected target clogging coefficient K = K is 8. 开机 +C=8+2=10, which equals the preset threshold of 10, meeting the self-cleaning condition and controlling the target device to perform self-cleaning.

[0116] 3. When the outdoor unit is severely enclosed, the target temperature difference T after startup. 温差 =25℃, then the target correction value C=4, that is, when the cumulative operating time of the target equipment meets 2200h, the start-up dirt blockage coefficient K 开机 The corrected target clogging coefficient K = K is 6. 开机 +C=6+4=10, which equals the preset threshold of 10, meeting the self-cleaning conditions and controlling the target device to perform self-cleaning.

[0117] Thus, the cumulative operating time for the target equipment to reach self-cleaning conditions varies depending on the degree of enclosure of the outdoor unit. As the enclosure status of the outdoor unit changes from slight to moderate to severe, the cumulative operating time of the target equipment decreases from 3600h to 3000h to 2200h. In practical applications, the effect is that as the enclosure degree of the outdoor unit increases, the cumulative operating time for the target equipment to reach self-cleaning conditions gradually decreases. That is, the higher the enclosure degree of the outdoor unit, the earlier the target equipment begins self-cleaning, making the self-cleaning of the outdoor unit in the enclosed location more accurate and timely, thus ensuring the cooling effect of the target equipment.

[0118] For example, Figure 4 A flowchart illustrating the specific steps of a self-cleaning control method for equipment is shown, as follows: Figure 4 As shown, the target device receives a power-on command and acquires the startup dirt and clogging coefficient and the ambient temperature at the moment of startup. The startup dirt and clogging coefficient is determined based on the target device's current cumulative running time. After the target device starts running, under stable operating conditions (i.e., when the temperature change within a preset time is less than or equal to a preset change value), the stable temperature of the device is acquired. Based on the stable temperature of the device and the ambient temperature, a target temperature difference is determined, and based on a first correspondence, a target correction value corresponding to the target temperature difference is acquired. The startup dirt and clogging coefficient is corrected based on the target correction value to obtain the target dirt and clogging coefficient. It is determined whether the target dirt and clogging coefficient is greater than or equal to a preset threshold. If so, the target device is controlled to perform a self-cleaning operation. After self-cleaning is completed, the cumulative running time of the target device is set as the initial running time; otherwise, the cumulative running time is updated based on the current running time and the target operating mode of the target device.

[0119] Figure 5 This is a schematic diagram of the structure of a self-cleaning control device for equipment provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the device may specifically include:

[0120] The first acquisition module 501 is used to acquire the startup dirt and blockage coefficient and startup ambient temperature of the target device;

[0121] The first correction module 502 is used to correct the start-up dirt and clogging coefficient based on the target temperature difference between the start-up ambient temperature and the stable temperature of the equipment, so as to obtain the target dirt and clogging coefficient; the stable temperature of the equipment is the temperature corresponding to the target equipment when it is in a stable operating state;

[0122] The first control module 503 is used to control the target device to perform a self-cleaning operation when the target dirt and clogging coefficient is greater than or equal to a preset threshold.

[0123] This invention provides a control device for self-cleaning equipment, which acquires the start-up dirt and clogging coefficient and the start-up ambient temperature of the target equipment; corrects the start-up dirt and clogging coefficient based on the target temperature difference between the start-up ambient temperature and the stable temperature of the equipment to obtain the target dirt and clogging coefficient; the stable temperature of the equipment is the temperature corresponding to the target equipment in a stable operating state; and controls the target equipment to perform self-cleaning operation when the target dirt and clogging coefficient is greater than or equal to a preset threshold. In this way, with the target equipment in the powered-on state, the startup dirt-clogging coefficient of the target equipment is first obtained. Then, based on the temperature difference between the startup ambient temperature and the target stable temperature of the equipment, the startup dirt-clogging coefficient is corrected to obtain the target dirt-clogging coefficient. The target dirt-clogging coefficient is used as the criterion for judging whether the target equipment needs to be self-cleaned. Based on the target dirt-clogging coefficient, the degree of dirt-clogging of the target equipment's condenser can be more accurately characterized, thus allowing for a more timely and accurate determination of when the target equipment needs to be self-cleaned. Compared to judging whether the target equipment needs to be self-cleaned based solely on the target equipment's operating time, this method can accurately and timely perform self-cleaning regardless of the target equipment's placement environment. This avoids the decrease in heat exchange efficiency and the inability of refrigerant to fully liquefy due to condenser dirt-clogging, ensuring the heat exchange efficiency and refrigerant liquefaction effect of the target equipment, and thus improving the cooling effect of the air conditioner to a certain extent.
