Description

Technical Field

[0001] The present invention relates to the technical field of intelligent devices, and in particular to a control method, device, electronic device and storage medium for device self-cleaning. Background Art

[0002] With the acceleration of modern urbanization, air conditioners, as an important household appliance, are subject to more and more restrictions on their installation locations and conditions. Especially in some high-end residential areas or apartments, in order to maintain the beauty and uniformity of the building's appearance, the installation location of the air conditioner outdoor unit is often designed in a closed or semi-closed position.

[0003] In the related art, the self-cleaning of the air conditioner is activated by detecting the running time of the air conditioner, that is, after reaching the set running time, the self-cleaning of the air conditioner will be activated. However, since the exhaust and air intake of the air conditioner set in a closed position will be hindered, the hot air that cannot be discharged will flow back to the air inlet, causing the dust and pollutants driven by the hot air return to easily deposit on the condenser, and more easily form dirty blockage. Therefore, when the actual air conditioner has not reached the set running time, the surface of the condenser has been covered with dust and pollutants, resulting in a decrease in heat exchange efficiency and the refrigerant cannot be fully liquefied, which in turn affects the cooling effect of the air conditioner.

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] Figure 1 is a flow chart of the steps of a method for controlling self-cleaning of equipment provided by an embodiment of the present invention, such as Figure 1 As shown, the method may include:

[0063] Step 101: Obtain the startup dirtiness and blockage coefficient and startup ambient temperature corresponding to the target device.

[0064] In the embodiment of the present invention, the target device may be an air conditioner or other device with a self-cleaning function. After the target device is turned on, the ambient temperature of the external unit is obtained by an ambient temperature sensor arranged at the external unit of the air conditioner as the startup ambient temperature. The ambient temperature sensor is used to detect the ambient temperature around the external unit of the air conditioner in real time. The startup dirty blocking coefficient corresponding to the target device is obtained. The startup dirty blocking coefficient is used to characterize the degree of dirty blocking corresponding to the external unit condenser of the target device when it is turned on. Based on the startup dirty blocking system, it can be determined whether the target device needs to perform self-cleaning of the external unit. The larger the startup dirty blocking coefficient, the more serious the degree of dirty blocking of the external unit condenser. The startup dirty blocking coefficient can be determined based on the cumulative running time of the target device, or, since the wind resistance will increase and the power of the external motor will decrease after the external unit condenser is dirty and blocked, the degree of dirty blocking of the external unit can also be determined by comparing the difference between the real-time power and the standard power of the external motor to obtain the startup dirty blocking coefficient. It can be understood that the startup dirty blocking coefficient can be determined based on other parameters related to the degree of dirty blocking of the condenser, and the embodiment of the present invention does not limit the method of determining the startup dirty blocking coefficient.

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

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

[0067] In an embodiment of the present invention, the cumulative running time of the target device is obtained, wherein the cumulative running time is determined based on the historical running mode of the target device and the equivalent coefficients corresponding to the preset different running modes. Exemplarily, the historical running mode of the target device and the actual running time corresponding to each historical running mode can be obtained, and for any historical running mode, the actual running time corresponding to the historical running mode is multiplied by the equivalent coefficient corresponding to the historical running mode to obtain the equivalent running time corresponding to the historical running mode, and the equivalent running time corresponding to each historical running mode is added to obtain the cumulative running time. It can be understood that in actual scenarios, the cumulative running time recorded by the target device can be updated based on the running time corresponding to the current running mode and the equivalent coefficient after each stop of the target device.

[0068] When the target device is in different operation modes, the air volume passing through the outdoor unit condenser is also different. Accordingly, the degree of dust and pollutants deposited on the condenser in different operation modes is also different. For example, compared with the operation based on the low windshield operation mode, the degree of dust and pollutants deposited on the condenser will be more serious after the target device is operated based on the high windshield operation mode. Therefore, it is necessary to perform equivalent processing on the operation time of different operation modes in order to determine a more realistic dirt and blockage coefficient based on the operation time.

[0069] Equivalent coefficients are set in advance for different operation modes. Specifically, one operation mode can be selected as the basic operation mode, and based on the basic operation mode, equivalent coefficients are set for other operation modes. For example, assuming that the basic operation mode is set to the high windshield operation mode, the equivalent coefficient corresponding to the high windshield operation mode is 1, the equivalent coefficient corresponding to the medium windshield operation mode is 0.8, and the equivalent coefficient corresponding to the low windshield operation mode is 0.6. When the target device runs for 1 hour based on the medium windshield operation mode, it is equivalent to running for 1 hour × 0.8 = 0.8 hours based on the high windshield operation mode.

[0070] Step 1012: Based on the accumulated running time and the second corresponding relationship, obtain the startup dirty and blocked coefficient.

[0071] In the embodiment of the present invention, as the fan operation time increases, the dirty blockage of the condenser will become more serious. At the same time, as the dirty blockage intensifies, the ventilation area of ​​the condenser will gradually decrease, thereby accelerating the dirty blockage rate. Therefore, as the operation time increases, the growth rate of the dirty blockage coefficient will gradually increase. Therefore, the startup dirty blockage coefficient can be obtained based on the accumulated operation time and the predetermined second corresponding relationship between the operation time and the dirty blockage coefficient. Among them, the second corresponding relationship is the corresponding relationship between the operation time and the dirty blockage coefficient. Exemplarily, the accumulated operation time t 等效 The second corresponding relationship with the dirty and blocked coefficient K can be as follows Figure 2As shown in the figure, as the cumulative running time of the outdoor fan increases, the degree of fouling and blocking of the outdoor condenser also increases, that is, the fouling and blocking coefficient continues to increase. And as the outdoor unit is fouled and blocked, the condenser passing area is reduced, and the fouling and blocking speed will accelerate, and finally present Figure 2 The curve of 下限 It can represent the lower limit of the cumulative running time when the target equipment needs to be self-cleaned. Correspondingly, K 下限 It can represent the lower limit of the dirty and clogging coefficient when the target equipment needs to be self-cleaned, that is, the preset threshold. 下限 When the target device needs to perform self-cleaning. It can be understood that the cumulative running time t 等效 The second corresponding relationship with the dirty blockage coefficient K can be a functional relationship, or a one-to-one correspondence through a mapping value table. It can be understood that the dirty blockage speed is related to the structure of the external unit, the condenser, and the parameters of the external unit motor, which can be determined through experimental measurements.

[0072] It can be understood that the dirty and blocked coefficient at the time of startup of the target device 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 started, so the value of the dirty and blocked coefficient is also different each time the device is started.

[0073] In an embodiment of the present invention, the cumulative operating time is determined based on the historical operating mode 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 dirtiness and blockage of the condenser, the operating time of the target device is equivalently calculated. This can make the degree of dirtiness and blockage of the condenser represented by the startup dirtiness and blockage coefficient determined based on the cumulative operating time more realistic.

[0074] Step 102: based on the target temperature difference between the startup environment temperature and the device stable temperature, the startup dirty and blocking coefficient is corrected to obtain a target dirty and blocking coefficient; the device stable temperature is the temperature corresponding to the target device in a stable operating state.

[0075] In an embodiment of the present invention, when the target device is in a stable operating state, the device stable temperature is determined based on the temperature detected by the ambient temperature sensor. The device stable temperature may be the ambient temperature of the target device's external unit when the target device is running smoothly, that is, when the parameters of the target device tend to be stable. The difference between the startup ambient temperature and the device stable temperature is obtained as the target temperature difference. Based on the target temperature difference, the startup dirty blocking coefficient is corrected to obtain the target dirty blocking coefficient. The target dirty blocking coefficient is used to characterize the actual degree of dirty blocking of the target device's condenser. The principle of correcting the startup dirty blocking coefficient based on the target temperature difference is that the more closed the external unit position is, the worse the air flow is, and the greater the difference in temperature rise of the external ring before and after the external unit is started, that is, the target temperature difference. For example, if the external unit is installed in an open position and the air inlet and outlet are not blocked, the external unit will have smooth air intake, and the temperature sensing package of the external ring will detect the actual temperature of the external ring. Although the condenser temperature rises after the outdoor unit in the open position is turned on, the heat such as heat radiation it emits will increase the temperature detected by the outer ring temperature sensor, but the change is relatively small. If the outdoor unit is installed in a closed position, it is closed on three sides and blocked by blinds on the front. Before starting up, due to natural convection heat exchange, the ambient temperature inside and outside the closed position is close, that is, the startup ambient temperature corresponding to the target device is close to the actual ambient temperature. After starting up, the air outlet of the air conditioner will be blocked by the blinds, causing the outdoor unit air outlet to flow back to the air inlet. The air in the closed position is continuously circulated and heated by the outdoor unit, which causes the outer ring temperature detected in the closed position to rise. In this way, the target temperature difference of the same device running under different outdoor unit assembly methods is different. Since the target temperature difference can represent the degree of closure of the outdoor unit installation of the target device, that is, the higher the target temperature difference, the higher the degree of closure of the outdoor unit installation. Correspondingly, when the target device is running, the degree of dirt and blockage of the condenser is higher. In the actual installation process, the closed position also has different sizes, blinds gaps, etc., and the degree of influence on the heat dissipation of the outdoor unit is different. Therefore, the dirty and clogging coefficient can be corrected to different degrees for different degrees of closed machine positions, that is, different target temperature differences correspond to different dirty and clogging coefficient correction values.

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

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

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

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

[0080] In an embodiment of the present invention, the condition for judging that the target device is in a stable operating state may include that the real-time temperature change value is less than the preset change value within a preset time length. Then, taking the preset time length as the judgment period, obtain the first real-time temperature corresponding to any first time and the second real-time temperature corresponding to the second time before the first time and with a time interval of the preset time length with the first time, and determine the temperature change value based on the first real-time temperature and the second real-time temperature. Among them, the target time length can be set according to demand, for example, 1 minute. The temperature change value is used to characterize the change in the real-time temperature of the internal and external units during the preset time length from the first time to the second time. Exemplarily, assuming that the first time is the Nth second after the target device is turned on, the second time is the Nth-60th second after the target device is turned on. Correspondingly, the first real-time temperature is T N , the second real-time temperature is T N-60 , then the temperature change value is T N -T N-60 .

[0081] Step 1023: When the temperature change value is less than or equal to a preset change value, determine the second real-time temperature as the device stable temperature.

[0082] In the embodiment of the present invention, when the temperature change value is less than or equal to the preset change value, it is determined that the target device is in a stable operating state, and the second real-time temperature is determined as the device stable temperature. When the temperature change value is greater than the preset change value, based on the next preset time length, it is determined whether the temperature change value is less than or equal to the preset change value until the target device is in a temperature operating state.

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

[0084] In the embodiment of the present invention, by judging whether the temperature change values ​​corresponding to different time periods within a preset time period are less than or equal to the preset change value, it is determined whether the target device is in a stable operating state, and then the stable temperature of the device is obtained. This can quickly and accurately judge the operating state of the target device, thereby improving the accuracy of the stable temperature of the device, and laying a foundation for accurately correcting the startup dirty blockage coefficient.

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

[0086] In an embodiment of the present invention, the dirty and blocked condition of the target device is judged according to the corrected target dirty and blocked coefficient, and it is confirmed whether the target device needs self-cleaning. When the target dirty and blocked coefficient is greater than or equal to a preset threshold value, which indicates that the dirty and blocked degree of the condenser of the target device has reached the degree that self-cleaning is required, the target device is controlled to perform a self-cleaning operation. Among them, the preset threshold value can be set according to actual needs. For example, the dirty and blocked coefficient corresponding to the need for self-cleaning of the target device can be determined as the preset threshold value. The embodiment of the present invention does not limit the value of the preset threshold value. For example, the user can be reminded that the external unit needs to be self-cleaned through the internal panel of the target device or the application software, or the target device can automatically start the self-cleaning operation by itself.

[0087] To summarize, in an embodiment of the present invention, the startup dirty and clogging coefficient and the startup ambient temperature corresponding to the target device are obtained; based on the target temperature difference between the startup ambient temperature and the device stable temperature, the startup dirty and clogging coefficient is corrected to obtain the target dirty and clogging coefficient; the device stable temperature is the temperature corresponding to the target device in a stable operating state; when the target dirty 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, when the target device is in the boot state, the boot dirty and blocking coefficient of the target device is first obtained, and then the boot dirty and blocking coefficient is corrected based on the target temperature difference between the boot environment temperature and the device stable temperature to obtain the target dirty and blocking coefficient. The target dirty and blocking coefficient is used as the judgment standard for whether the target device needs to be self-cleaned. The target dirty and blocking coefficient can more accurately characterize the degree of dirtiness and blocking of the condenser of the target device, and thus the time when the target device needs to be self-cleaned can be more timely and accurately judged. Compared with judging whether the target device needs to be self-cleaned only based on the operating time of the target device, when the target device is placed in different environments, it can accurately and timely perform self-cleaning, avoiding the decrease in heat exchange efficiency of the target device due to condenser dirtiness and blocking, and the inability to fully liquefy the refrigerant, thereby ensuring the heat exchange efficiency of the target device and the liquefaction effect of the refrigerant, thereby also 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 a target temperature difference between the startup environment temperature and the device stable temperature.

[0090] Step 202: Determine a target correction value corresponding to the target temperature difference based on the target temperature difference and the first corresponding relationship.

[0091] In the embodiment of the present invention, when the target device is in a stable operating state, the device stable temperature is obtained, and the difference between the device stable temperature and the startup environment temperature is calculated to obtain the target temperature difference. Based on the target temperature difference and the first corresponding relationship, the temperature correction value corresponding to the target temperature difference is determined. Among them, the first corresponding relationship is the corresponding relationship between the temperature difference and the temperature correction value.

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

[0093] Step 2021: When the target temperature difference is less than the first temperature, determine the target correction value to be the first correction value.

[0094] Step 2022: When 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: When the target temperature value is greater than or equal to the second temperature, determine the target correction value to be a second correction value.

[0096] In the embodiment of the present invention, since the degree of enclosure of the external environment in which the outdoor unit of the target device is located will affect the dirtiness and blockage of the condenser to varying degrees, the dirtiness and blockage coefficient can be corrected to varying degrees for different degrees of enclosure based on the target temperature difference that can characterize the degree of enclosure of the external environment, so that the dirtiness and blockage coefficient is more consistent with the actual degree of dirtiness and blockage. Specifically, according to the correlation between the temperature difference and the dirty and blocked condition of the condenser in the actual scenario, the temperature difference can be divided into three intervals. When the target temperature difference is less than the first temperature, the dirty and blocked condition of the condenser is less affected by the degree of enclosure of the outdoor unit environment, and accordingly, 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 dirty and blocked condition of the condenser is positively correlated with the degree of enclosure of the outdoor unit environment, and accordingly, the correction value will increase with the increase of the target temperature difference, that is, the larger the target temperature difference, the higher the degree of enclosure of the outdoor unit environment, the more serious the dirty and blocked condition of the condenser, and the larger the correction value will be, so that the target dirty and blocked coefficient can be more in line with the actual dirty and blocked condition; when the target temperature difference is greater than a certain upper limit, according to the operating characteristics of the target equipment, the impact on the dirty and blocked condition of the condenser 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 the same value. Based on this, when the target temperature difference is less than the first temperature, the target correction value can be determined to be the first correction value; when the target temperature difference is greater than or equal to the first temperature and less than the second temperature, the target correction value can be determined based on the preset temperature difference and the target positive correlation coefficient of the correction value; when the target temperature value is greater than or equal to the second temperature, the target correction value can be determined to be the second correction value. Wherein, the target positive correlation coefficient is determined based on the corresponding relationship between the temperature difference and the correction value when the temperature difference is in the first temperature and the second temperature interval. When the temperature difference is in the first temperature and the second temperature interval, the temperature difference is positively correlated with the correction value, that is, 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 can be determined according to experimental tests, and the embodiment of the present invention does not limit this.

[0097] It can be understood that the first corresponding relationship can be a function or a preset numerical table. The first corresponding relationship is related to different external unit types and external unit structural parameters of the target device, and can be obtained through testing according to actual scenarios.

[0098] For example, the temperature difference T 温差 The first corresponding relationship with the temperature correction value C can be expressed as Figure 3 As shown, C and T 温差 The corresponding relationship is divided into three intervals. The first interval: T 温差 <T温差下限 , the external unit is not affected by the closed position or the impact is small, C = 0, that is, no actual correction effect is produced on the dirty blockage coefficient K; the second interval: T 温差下限 ≤T 温差 ≤T 温差上限 , with T 温差 The greater the heat dissipation effect on the outdoor unit, the greater the temperature correction value C, and the greater the correction of the dirty blockage coefficient K; the third interval: T 温差 >T 温差上限 , C=C 上限 , the correction effect of the dirty and clogging coefficient K value is also maximized. In order to avoid excessive correction of the C value, which leads to too frequent self-cleaning and affects the user experience, the subsequent T 温差 As the C value increases, it no longer increases and is always equal to C 上限 .

[0099] In an embodiment of the present invention, by determining a target correction value based on the corresponding relationship between the target temperature difference and the degree of dirtiness and blockage of the condenser when the target device is operating in closed spaces with different degrees of closure, the target device can be adapted 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 deployment environment of the target device can be improved.

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

[0101] In the embodiment of the present invention, the target dirty blocking coefficient is determined based on the startup dirty blocking coefficient and the target correction value. Specifically, the startup dirty blocking coefficient and the target correction value can be added to obtain the target dirty blocking coefficient. For example, assuming that the startup dirty blocking coefficient is K 开机 , the target correction value is C, then the target dirty blocking coefficient K = K 开机 +C.

[0102] In an embodiment of the present invention, by obtaining a target correction value based on a target temperature difference, the dirty and clogging coefficient can be adjusted to eliminate or reduce errors caused by placement environments of target equipment external units with different degrees of sealing, thereby improving the accuracy of the target dirty and clogging coefficient, so that the target dirty and clogging coefficient can more realistically characterize the dirty and clogging conditions of the condenser, thereby facilitating timely self-cleaning of the equipment based on the dirty and clogging conditions.

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

[0104] Step 301: When the target dirty and congestion coefficient is less than the preset threshold, if the target device stops running, the accumulated running time is updated based on the current running time corresponding to the target device and the target running mode corresponding to the target device.

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

[0106] For example, assuming that when the target device is powered on for the first time, the outdoor unit runs in high wind speed mode for 100 hours, then the equivalent running time of this operation is 100 hours. When powered on for the second time, the outdoor fan runs in high wind speed mode for 80 hours and in medium wind speed mode for 20 hours, then the equivalent running time of this operation = high wind speed running time + medium wind speed running time × equivalent coefficient corresponding to medium wind speed running mode = 80 + 20 * 0.8 = 96 hours. Correspondingly, if the device only performs these two power-on processes, the cumulative running time of the fan = the first equivalent running time + the second equivalent running time = 100 + 96 = 196 hours.

[0107] In an embodiment of the present invention, when the target dirty and congestion coefficient is less than a preset threshold, the accumulated running time will be updated based on the running time and the running mode after the current operation is completed. Through equivalent operations, accurate time calculations can be performed 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, the embodiment of the present invention may include the following steps:

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

[0110] In the embodiment of the present invention, after the target device starts self-cleaning, it is considered that the dirty blockage of the external unit of the target device has been processed. Therefore, the cumulative running time, dirty blockage coefficient and related correction parameters of the target device can be initialized, including setting the cumulative running time of the target device to the initial running time, the dirty blockage coefficient to the initial coefficient, and the related correction parameters to the initial value. Exemplarily, the cumulative running time, dirty blockage coefficient and related correction parameters of the target device can be reset to zero, that is, the dirty blockage coefficient K = 0, the related correction parameter C = 0, the cumulative running time t of the target device 等效 =0.

[0111] In the embodiment of the present invention, after the target device performs self-cleaning, the accumulated running time of the target device is reset so that the target device can make a judgment on the next device self-cleaning.

[0112] For example, assuming that the preset threshold is 10, that is, when the target dirty and blocked coefficient is greater than or equal to 10, the target device is controlled to perform self-cleaning. Figure 2 It can be determined that when the cumulative running time of the target device is 3600h, the corresponding startup dirty blocking coefficient K is 10; when the cumulative running time is 3000h, the corresponding startup dirty blocking coefficient K is 8; when the cumulative running time is 2200h, the corresponding startup dirty blocking coefficient K is 6. And assume Figure 3 T 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 =25℃, the correction value of the dirty and clogging coefficient C reaches the maximum value C 上限 , and is always equal to C 上限 .

[0113] Based on the above conditions, according to the different degrees of enclosure of the outdoor unit, the operation can be as follows:

[0114] 1. When the outdoor unit is open and unobstructed or slightly enclosed, the target temperature difference T after powering on 温差 <5℃, the target correction value C=0, and no actual correction effect is produced. That is, when the cumulative running time of the target equipment meets 3600h, the startup dirty blockage coefficient K 开机 is 10, then the target dirty and blocked coefficient K = K 开机 +C=10+0=10, which is equal to the preset threshold value 10, satisfies the self-cleaning condition, and controls the target device to perform self-cleaning.

[0115] 2. When the external unit is in a medium degree of enclosure, the target temperature difference after startup is T 温差 =15℃, then the target correction value C=2, that is, when the cumulative running time of the target equipment meets 3000h, the startup dirty blocking coefficient K 开机 =8, the corrected target dirty and blocked coefficient K = K 开机 +C=8+2=10, which is equal to the preset threshold value 10, satisfies the self-cleaning condition, and controls the target device to perform self-cleaning.

[0116] 3. When the external 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 running time of the target equipment meets 2200h, the startup dirty blockage coefficient K 开机 is 6, and the corrected target dirty and blocked coefficient K = K 开机 +C=6+4=10, which is equal to the preset threshold value 10, satisfies the self-cleaning condition, and controls the target device to perform self-cleaning.

[0117] In this way, the system has different cumulative running time when the target equipment reaches the self-cleaning condition according to the different degrees of enclosure of the outdoor unit. As the enclosure state of the outdoor unit changes from mild to moderate to severe, the cumulative running time of the target equipment changes from 3600h to 3000h to 2200h. The actual use effect in the actual scenario is that as the degree of enclosure of the outdoor unit increases, the cumulative running time when the target equipment reaches the self-cleaning condition gradually decreases, that is, the higher the degree of enclosure of the outdoor unit, the earlier the target equipment performs self-cleaning, so that the self-cleaning of the outdoor unit in the closed position is more accurate and timely, ensuring the cooling effect of the target equipment.

[0118] For example, Figure 4 A flow chart showing the specific steps of a method for controlling self-cleaning of equipment is shown in FIG. Figure 4 As shown, the target device receives the command to start up, and obtains the startup dirty and blocked coefficient and the startup ambient temperature at the startup time. The startup dirty and blocked coefficient is determined based on the current cumulative running time of the target device. After the target device starts to run, when the target device is in a stable running state, that is, when the temperature change value within the preset time is less than or equal to the preset change value, the stable temperature of the device is obtained. Based on the stable temperature of the device and the startup ambient temperature, the target temperature difference is determined, and based on the first corresponding relationship, the target correction value corresponding to the target temperature difference is obtained. The startup dirty and blocked coefficient is corrected based on the target correction value to obtain the target dirty and blocked coefficient. It is judged whether the target dirty and blocked coefficient is greater than or equal to the preset threshold value. If so, the target device is controlled to perform a self-cleaning operation. After the self-cleaning is completed, the cumulative running time of the target device is set to the initial running time; if not, the cumulative running time is updated based on the current running time corresponding to the target device and the target running mode corresponding to the target device.

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

[0120] The first acquisition module 501 is used to obtain the startup dirty and blocked coefficient and startup ambient temperature corresponding to the target device;

[0121] A first correction module 502 is used to correct the startup dirty blocking coefficient based on the target temperature difference between the startup environment temperature and the device stable temperature to obtain a target dirty blocking coefficient; the device stable temperature is the temperature corresponding to the target device 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 dirtiness and blockage coefficient is greater than or equal to a preset threshold.

[0123] An embodiment of the present invention provides a control device for equipment self-cleaning, which obtains a startup dirty and clogging coefficient and a startup ambient temperature corresponding to a target equipment; based on a target temperature difference between the startup ambient temperature and the equipment stable temperature, the startup dirty and clogging coefficient is corrected to obtain a target dirty and clogging coefficient; the equipment stable temperature is a temperature corresponding to the target equipment in a stable operating state; when the target dirty and clogging coefficient is greater than or equal to a preset threshold, the target equipment is controlled to perform a self-cleaning operation. In this way, when the target device is in the boot state, the boot dirty and blocking coefficient of the target device is first obtained, and then the boot dirty and blocking coefficient is corrected based on the target temperature difference between the boot environment temperature and the device stable temperature to obtain the target dirty and blocking coefficient. The target dirty and blocking coefficient is used as the judgment standard for whether the target device needs to be self-cleaned. The target dirty and blocking coefficient can more accurately characterize the degree of dirtiness and blocking of the condenser of the target device, and thus the time when the target device needs to be self-cleaned can be more timely and accurately judged. Compared with judging whether the target device needs to be self-cleaned only based on the operating time of the target device, when the target device is placed in different environments, it can accurately and timely perform self-cleaning, avoiding the decrease in heat exchange efficiency of the target device due to condenser dirtiness and blocking, and the inability to fully liquefy the refrigerant, thereby ensuring the heat exchange efficiency of the target device and the liquefaction effect of the refrigerant, thereby also improving the cooling effect of the air conditioner to a certain extent.
