[0030] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0031] A method, device and electronic device for detecting abnormal drainage of an air conditioner according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0032] Figure 1 A schematic flow chart of a method for detecting abnormal drainage of an air conditioner provided by an embodiment of the present application. As Figure 1 shown, the method includes the following steps:

[0033] S101, obtaining the total amount of condensed water generated by the evaporator within a first set time period and the total drainage amount of the condensed water discharged through the drainage pipe.

[0034] In some implementations, the first set time period can be a preset time; optionally, the first set time period can be 5 minutes.

[0035] The function of the evaporator is to utilize the fact that liquid low-temperature refrigerant is easy to evaporate under low pressure, transform into steam and absorb the heat of the medium to be cooled, so as to achieve the refrigeration purpose. That is to say, during the operation of the evaporator, the temperature of the evaporator copper tube is lower than the dew point temperature corresponding to the nearby temperature, and water vapor in the air will precipitate, thus forming condensed water.

[0036] It can be understood that the condensed water generated on the evaporator will drip into the water receiving tank and then be discharged through the drainage pipe. If the drainage pipe is dirty and blocked or bent at this time, the condensed water cannot be discharged in time, which may cause the accumulation of condensed water and the situation of dripping leakage at the indoor unit, affecting the user's use.

[0037] In some implementations, the total amount of condensed water generated by the evaporator within the first set time period can be obtained, that is, the total amount of condensed water generated within 5 minutes. Optionally, the amount of condensed water at each moment can be obtained, and the total amount of condensed water can be obtained according to the amount of condensed water at each moment.

[0038] Further, obtain the total drainage volume of the condensed water discharged by the drain pipe within the first set duration, that is, the total drainage volume discharged within 5 minutes. Under normal circumstances, the total amount of condensed water generated by the evaporator should be the same as the discharged drainage volume to ensure the normal operation of the air conditioner. Optionally, the total drainage volume can be calculated based on the water flow rate and the pipe area, and the pipe area is the pipe area of the drain pipe, which can be determined according to the factory specifications of the air conditioner.

[0039] S102. Determine the difference between the total amount of condensed water and the total drainage volume.

[0040] It can be understood that during the normal operation of the air conditioner, the total amount of condensed water generated is equal to the total drainage volume. Therefore, the difference between the total amount of condensed water and the total drainage volume can be obtained, and whether there is a problem with the drain pipe can be determined based on this difference.

[0041] S103. Determine whether there is abnormal drainage in the drain pipe according to the difference.

[0042] In some implementations, if the difference is zero, that is, the amount of condensed water and the total drainage volume are equal, it can be considered that all the condensed water generated by the evaporator is discharged by the drain pipe, and the working state of the drain pipe is normal.

[0043] In some implementations, if the difference is not zero, that is, the total amount of condensed water is greater than the total drainage volume, then the condensed water generated by the evaporator is not completely discharged by the drain pipe. Therefore, it can be considered that there are problems such as blockage in the drain pipe, resulting in abnormal drainage in the drain pipe.

[0044] In some implementations, the differences in multiple time periods can also be collected, that is, the total amount of condensed water generated by the evaporator and the total drainage volume of the drain pipe within multiple set times are collected, and the difference between the total amount of condensed water and the total drainage volume within each set time is calculated; if the differences in the obtained multiple set times are all not zero, it is determined that there is abnormal drainage in the drain pipe; or the cumulative value of all the differences is calculated to determine the amount of condensed water not discharged within this time range. If this amount of condensed water is greater than the set threshold, it is determined that there is abnormal drainage in the drain pipe.

[0045] In this embodiment, the total amount of condensed water generated by the evaporator within the set time and the total drainage volume of the condensed water discharged by the drain pipe are obtained, and whether there is abnormal drainage in the drain pipe is determined according to the difference between the total amount of condensed water and the total drainage volume. When the drain pipe is working normally, the total amount of condensed water and the total drainage volume should be the same. Therefore, according to the difference, it can be directly determined whether the drain pipe discharges all the condensed water, so as to judge the drainage situation of the drain pipe and improve the efficiency of detecting abnormal drainage in the drain pipe.

[0046] Figure 2 It is a schematic flowchart of another method for detecting abnormal drainage of an air conditioner provided by an embodiment of the present application.

[0047] As Figure 2 shown, the method includes the following steps:

[0048] S201, obtain the total amount of condensed water generated by the evaporator within the first set time period and the total drainage amount of the condensed water discharged by the drain pipe.

[0049] In the embodiments of the present application, the implementation method of step S201 can be implemented in any one of the embodiments of the present disclosure, and no limitation is made herein, nor will it be elaborated further.

[0050] S202, determine the difference between the total amount of condensed water and the total drainage amount.

[0051] In the embodiments of the present application, the implementation method of step S202 can be implemented in any one of the embodiments of the present disclosure, and no limitation is made herein, nor will it be elaborated further.

[0052] S203, determine whether the current timing moment reaches the second set time period.

[0053] Wherein, the second set time period is greater than the first set time period. In some implementations, the second set time period can be a relatively long time length. When the timing moment reaches the second set time period, the total amount of condensed water generated by the evaporator and the total drainage amount of the condensed water discharged by the drain pipe within the second set time period can be obtained and analyzed.

[0054] In some implementations, the timing moment can start timing from the first time the total amount of condensed water generated by the evaporator and the total drainage amount of the condensed water discharged by the drain pipe are obtained, that is, from the time when the total amount of condensed water and the total drainage amount for the first set time period are collected, until the timing moment reaches the second set time period.

[0055] Optionally, the length of the second set time period can be a multiple of the first set time period. For example, if the first set time period is 5 minutes, the second set time period can be 30 minutes, 40 minutes, or 1 hour, etc.

[0056] S204, if the current timing moment reaches the second set time period, determine whether there is abnormal drainage in the drain pipe according to the difference within the second set time period.

[0057] Optionally, the first set time period can be used as an analysis unit. Since the length of the second set time period may be multiple first set time periods, multiple analysis units can be determined within the second set time period, and the total amount of condensed water generated by the evaporator and the total drainage amount of the condensed water discharged by the drain pipe under each analysis unit can be obtained, so as to determine the difference between the total amount of condensed water and the total drainage amount under each analysis unit.

[0058] It can be understood that the second set duration includes multiple first set durations. A difference between the total condensate volume and the total drainage volume can be obtained under each first set duration. Therefore, a difference sequence can be determined based on all the differences within the second set duration.

[0059] Furthermore, determine the average value of the difference sequence, and based on the average value, determine whether there is abnormal drainage in the drain pipe.

[0060] In some implementations, it can be determined whether the last difference in the difference sequence is greater than a set value, that is, whether the latest acquired difference is greater than the set value. In response to the latest acquired difference being greater than the set value, based on the average value, determine whether there is abnormal drainage in the drain pipe.

[0061] Optionally, the set value can be zero. That is to say, when the latest acquired difference is zero, it can be determined that there is no abnormal drainage problem in the drain pipe, and there is no need to make a judgment based on the difference sequence; correspondingly, when the latest acquired difference is greater than zero, based on the average value of the difference sequence, determine whether there is abnormal drainage in the drain pipe.

[0062] Furthermore, when the last difference in the difference sequence is greater than the set value, it can be determined whether the last difference in the difference sequence is greater than the average value, and this average value is the average value of the difference sequence. Based on whether the last difference is greater than the average value, determine whether there is an abnormality in the drain pipe.

[0063] If the last difference in the difference sequence is greater than the average value, obtain the last N differences in the difference sequence, where N is a positive integer and N is less than the number of differences in the difference sequence; determine whether the N differences are greater than the average value. In response to the N differences all being greater than the average value, determine that there is abnormal drainage in the drain pipe. That is to say, when the last difference in the difference sequence is greater than the average value, obtain the last N consecutive differences in the difference sequence, determine whether the last N consecutive differences are greater than the average value. When the last N consecutive differences are all greater than the average value, it can be determined that the drainage volume of the drain pipe for condensate is gradually decreasing. Therefore, it can be determined that there is abnormal drainage in the drain pipe.

[0064] Exemplarily, assume that there are 10 differences in the difference sequence, calculate the average value of the difference sequence, and determine whether the 10th difference in the difference sequence is greater than the average value. If the 10th difference is greater than the average value, obtain the last N differences in the difference sequence. For example, when N is 3, obtain the 8th difference, the 9th difference, and the 10th difference in the difference sequence, and determine whether the 8th difference, the 9th difference, and the 10th difference are all greater than the average value. If the 8th difference, the 9th difference, and the 10th difference are all greater than the average value, then there is abnormal drainage in the drain pipe. If the 8th difference, the 9th difference, and the 10th difference are not all greater than the average value, continue to monitor the drainage situation of the drain pipe.

[0065] In some implementations, if N consecutive differences in the difference sequence are less than or equal to the average value, or if the last difference in the difference sequence is less than or equal to the average value, the first cumulative value of the difference sequence can be obtained; based on the first cumulative value and the volume of the drain pipe, it is determined whether there is abnormal drainage in the drain pipe. It can be understood that the first cumulative value of the difference sequence is the sum of all differences in the difference sequence. Since the difference reflects the amount of condensed water not discharged from the drain pipe, the larger the first cumulative value, the more condensed water is not discharged from the drain pipe within the second set time period, and the more likely there is abnormal drainage in the drain pipe.

[0066] In some implementations, the determination threshold for drainage abnormality of the drain pipe can be determined according to the volume of the drain pipe; in response to the first cumulative value being greater than or equal to the determination threshold for drainage abnormality, it is determined that there is abnormal drainage in the drain pipe.

[0067] Optionally, a certain proportion of the volume of the drain pipe can be used as the determination threshold. For example, 60% of the volume of the drain pipe is used as the determination threshold. When the first cumulative value is greater than or equal to 60% of the volume of the drain pipe, that is, greater than or equal to the determination threshold, it is determined that there is abnormal drainage in the drain pipe; correspondingly, when the first cumulative value is less than 60% of the volume of the drain pipe, that is, less than the determination threshold, it is determined that there is no abnormality in the drain pipe for the time being.

[0068] S205, if the current timing moment has not reached the second set time period, based on the differences obtained from the start of timing to the current timing moment, it is determined whether there is abnormal drainage in the drain pipe.

[0069] Optionally, when the current timing moment has not reached the second set time period, the differences obtained from the start of timing to the current timing moment can be summed to obtain a second cumulative value; based on the second cumulative value and the volume of the drain pipe, the state of the drain pipe is determined. That is, starting from the start of timing, every time the first set time period is satisfied, the total amount of condensed water and the total amount of drained water in this first set time period are obtained, and the difference between the total amount of condensed water and the total amount of drained water is calculated, and so on until the current timing moment, all differences are determined and summed to obtain the second cumulative value; since the difference reflects the amount of condensed water not discharged from the drain pipe, the larger the second cumulative value, the more condensed water is not discharged from the drain pipe from the start of the timing moment to the current moment, and the more likely there is abnormal drainage in the drain pipe.

[0070] In some implementations, the determination threshold for drainage abnormality of the drain pipe can be determined according to the volume of the drain pipe; in response to the second cumulative value being greater than or equal to the determination threshold for drainage abnormality, it is determined that there is abnormal drainage in the drain pipe.

[0071] Optionally, a certain proportion of the volume of the drain pipe can be used as a determination threshold, for example, 60% of the volume of the drain pipe. That is to say, 60% of the volume of the drain pipe is used as the determination threshold. When the second cumulative sum value is greater than or equal to 60% of the volume of the drain pipe, that is, greater than or equal to the determination threshold, it is determined that there is abnormal drainage in the drain pipe; correspondingly, when the second cumulative sum value is less than 60% of the volume of the drain pipe, that is, less than the determination threshold, it is determined that there is no abnormality in the drain pipe for the time being.

[0072] Furthermore, if it is determined that there is abnormal drainage in the drain pipe, the operating frequency of the compressor can be reduced; and / or, a reminder message for abnormal drainage of the drain pipe can be generated. That is to say, when it is determined that there is abnormal drainage in the drain pipe, the operating frequency of the compressor can be reduced to increase the pipe temperature of the evaporator and reduce the generation of condensate; and / or, a reminder message for abnormality can be generated to remind relevant personnel that there is abnormal drainage in the drain pipe and to process the abnormal drainage in a timely manner.

[0073] In this embodiment, it is determined whether the current timing moment reaches the second set duration. According to whether the second set duration is reached, the difference sequence or the second cumulative sum value of the differences within the second set duration is determined; the average value of the difference sequence is obtained, and different judgment methods are determined according to whether the last difference in the difference sequence is greater than the average value to judge whether there is abnormal drainage in the drain pipe, or according to whether the second cumulative sum value is greater than or equal to the determination threshold, it is determined whether there is abnormal drainage in the drain pipe. According to the average value of the difference sequence, different abnormal determination methods are determined to improve the accuracy of detecting abnormal drainage in the drain pipe, and an alarm is given or the operating frequency is adjusted when an abnormality is determined, thereby enhancing the user experience.

[0074] Figure 3 It is a schematic flowchart of another method for detecting abnormal drainage of an air conditioner provided by an embodiment of the present application.

[0075] As Figure 3 shown, the method includes the following steps:

[0076] S301, within the first set duration, detect the indoor air humidity, outdoor air humidity, the number of indoor people, and the indoor area at set time intervals to obtain the state information of the air conditioner at different detection moments.

[0077] In some implementations, the air conditioning system may include sensors and infrared devices.

[0078] In some implementations, the air humidity can be detected based on sensors; in some implementations, the number of indoor people can be determined by detecting the heat sources and infrared characteristics in the room through an infrared detection method;

[0079] In some implementations, the housing area can be determined by the value set by the user, or the current housing area of the air conditioner can be estimated by modeling a series of its own data such as the indoor and outdoor environmental temperatures and the rate of change, the pipe temperature, and the compressor load after the air conditioner has been running for a long time.

[0080] Optionally, the status information of the air conditioner may at least include the indoor air moisture content, the outdoor air moisture content, the number of indoor occupants, and the indoor area.

[0081] Optionally, the first set duration may be 5 minutes, and the set time interval may be 30 seconds.

[0082] S302. Determine the total amount of condensed water generated by the evaporator within the first set duration according to the status information and the attribute information of the air conditioner.

[0083] Optionally, the attribute information of the air conditioner may be its own parameters when it leaves the factory, such as the rated power, the rated cooling capacity, the fresh air volume, and the energy efficiency ratio, etc.

[0084] Optionally, for each time interval, the first amount of condensed water generated by the evaporator within the time interval may be determined according to the attribute information and the status information at the detection moment corresponding to the time interval; perform calculus on the first amounts of condensed water within all time intervals to obtain the total amount of condensed water.

[0085] In some implementations, the sources of condensed water during the operation of the air conditioner mainly include the fresh air moisture load part and the moisture released by people, such as the moisture content in the air itself, the moisture content of the fresh air entering the room from the outdoor side, and the number of people in the current indoor space.

[0086] Optionally, the second amount of condensed water generated by the fresh air moisture load and the third amount of condensed water generated by the moisture released by people within the time interval may be determined according to the attribute information and the status information, and the second amount of condensed water and the third amount of condensed water generated within the time interval are summed to obtain the first amount of condensed water generated by the evaporator within the time interval.

[0087] In some implementations, for the fresh air moisture load part, the fresh air volume, the fresh air compensation amount, and the fresh air density of the air conditioner itself may be determined according to the attribute information; according to the fresh air volume and the fresh air compensation amount, the total fresh air volume of the air conditioner is obtained, and the total fresh air volume is multiplied by the fresh air density to obtain the air volume mass of the air conditioner; according to the outdoor air moisture content and the indoor air moisture content, the moisture content difference of the air moisture content is obtained; according to the air volume mass and the moisture content difference, the second amount of condensed water is determined.

[0088] In some implementations, the fresh air compensation amount refers to the compensation value caused by the environment where the air conditioner is located. For example, the fresh air compensation amount caused by external environmental factors of the air conditioner such as a fresh air machine installed outdoors and air leakage through doors and windows may be a pre-given compensation value.

[0089] Optionally, the calculation of the second condensate water volume generated by the fresh air humidity load part can be:

[0090] m = ρ(Q x + Q2)×(d W - d N )×10 -2

[0091] where m represents the second condensate water volume generated by the fresh air humidity load part; Q x represents the fresh air volume of the air conditioner itself; Q2 represents the fresh air compensation volume caused by other factors; ρ represents the fresh air density; ρ(Q x + Q2) represents the air volume mass; d W represents the moisture content of the outdoor air; d N represents the moisture content of the indoor air; (d W - d N ) represents the moisture content difference.

[0092] Furthermore, for the part of moisture released by people, the cluster coefficient can be determined according to the number of indoor people and the indoor area; the total moisture released by indoor people can be determined according to the number of indoor people and the calibrated moisture release amount of a single person; based on the cluster coefficient and the total moisture release amount, the third condensate water volume can be determined.

[0093] It can be understood that the cluster coefficient is a reduction coefficient considered according to different situations such as the personnel composition and the degree of density, based on the heat dissipation and moisture release amounts of adult men; the third condensate water volume generated by the part of moisture released by people is determined according to the cluster coefficient.

[0094] Optionally, the calculation of the third condensate water volume generated by the part of moisture released by people can be:

[0095]

[0096] where ∑d τ represents the third condensate water volume generated by the part of moisture released by people; represents the cluster coefficient; n τ represents the number of indoor people at the current moment; g represents the calibrated moisture release amount of a single person, such as the moisture release amount of an adult man.

[0097] Furthermore, the second condensate water volume generated by the fresh air humidity load part and the third condensate water volume generated by the part of moisture released by people are added together to obtain the first condensate water volume generated by the evaporator within the current time interval.

[0098] Further, after determining the first condensate volume in each time interval within the first set duration, considering the ever-changing indoor environment, the total condensate volume generated within the first set duration can be calculated using calculus based on the first condensate volumes generated in each time interval. S303. Obtain the total drainage volume of the condensate discharged through the drain pipe within the first set duration.

[0099] Optionally, an intercepting device can be added at the outlet of the drain pipe. When the condensate accumulates to a certain amount, the intercepting device opens to discharge the condensate.

[0100] In some implementations, the number of times the intercepting device of the drain pipe is opened within the first set duration can be obtained; since the intercepting device opens every time the condensate accumulates to a certain amount, the drainage volume of the drain pipe within the first set duration can be determined based on the number of times the intercepting device is opened and the drain pipe flow rate after each opening.

[0101] Optionally, assuming that the number of times the intercepting device is opened within the first set duration is n and the drain pipe flow rate after each opening is v, the drainage volume of the drain pipe within the first set duration can be V = n * v.

[0102] S304. Determine the difference between the total condensate volume and the total drainage volume.

[0103] In the embodiments of the present application, the implementation method of step S304 can be implemented in any one of the embodiments of the present disclosure, and no limitation is made here, nor will it be elaborated further.

[0104] S305. Determine whether there is abnormal drainage in the drain pipe according to the difference.

[0105] In the embodiments of the present application, the implementation method of step S305 can be implemented in any one of the embodiments of the present disclosure, and no limitation is made here, nor will it be elaborated further.

[0106] In this embodiment, according to the status information and attribute information of the air conditioner within a period of time, the corresponding first condensate volume is obtained, and then the first condensate volumes in all time intervals are added together to obtain the total condensate volume, improving the accuracy of obtaining the total condensate volume; an intercepting device is added to the drain pipe for condensate discharge, and the total drainage volume is determined based on the number of times the intercepting device is opened, and then the difference is obtained and analyzed based on the total condensate volume and the total drainage volume, improving the accuracy and reliability of the difference analysis.

[0108] As Figure 4 shown, the method includes the following steps:
