[0031] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0032] It is considered that when the condensate water on the indoor heat exchanger is excessive during the refrigeration or dehumidification operation of the air conditioner (such as a household split air conditioner), the heat exchange efficiency of the air conditioner and the user experience will be affected. Some schemes provide an air conditioner and an air conditioner indoor unit water pump control method, the air conditioner comprising a refrigerant circulation loop, an outdoor heat exchanger and an indoor heat exchanger, an indoor unit water pump, an indoor unit float switch, an indoor environment humidity sensor and a controller, the controller being configured to: determine a humidity interval in which the indoor humidity is located based on the indoor humidity, the humidity interval comprising a high humidity interval, a medium humidity interval or a low humidity interval; and control the opening state of the water pump based on the humidity interval and the alarm signal of the indoor unit float switch when the air conditioner is operated in a refrigeration mode, thereby achieving intelligent control of the water pump and avoiding energy waste. The present application adjusts the opening state of the water pump through water level control and performs drainage. However, this scheme controls the opening of the water pump through water level change, does not adjust whether the condensate water on the indoor heat exchanger is hanging, and does not process the hanging water condition of the indoor heat exchanger.

[0033] Some other schemes provide an air conditioner and a water removal control method thereof. When a mobile air conditioner is operated for a long time, a large amount of condensate water is generated. By removing water from the water tank in advance, the accumulation speed of the condensate water is prevented from being too fast, thereby preventing the air conditioner from stopping, and ensuring the continuous operation of the air conditioner while reducing the formation speed of the condensate water. This scheme removes water from the water tank in advance through water level change in the water tank, does not determine whether the condensate water on the heat exchanger is hanging, and does not process the hanging water condition of the heat exchanger.

[0034] In addition, the indoor unit of the air conditioner (such as a household split variable frequency air conditioner) collects the condensate water of the air conditioner through a water collecting tray. The indoor unit of the air conditioner is provided with a drain hole. During the installation of the air conditioner, the user connects the drain hole with a drain pipe to drain the condensate water of the indoor unit to the outdoor.

[0035] Therefore, the present application provides a control method of an air conditioner, specifically a running control method of a variable frequency air conditioner. The condensate water attached to the indoor heat exchanger is detected to adjust the running state of the air conditioner, reduce the hanging water condition of the indoor heat exchanger of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the energy saving performance.

[0036] According to an embodiment of the present application, a control method of an air conditioner is provided, as shown in Figure 1 The flowchart of an embodiment of the method of the present application is shown. The air conditioner has an outdoor unit and an indoor unit, the outdoor unit has a compressor, and the indoor unit has an indoor heat exchanger and an indoor fan; a drainage amount detection device is arranged in the drainage passage of the indoor unit, for detecting the drainage amount of the condensed water in the drainage passage of the indoor unit as the drainage amount of the condensed water generated on the indoor heat exchanger; in the scheme of the present application, as shown in Figure 1 The control method of the air conditioner comprises steps S110 to S150.

[0037] At step S110, in the case that the air conditioner runs in a cooling mode or a dehumidifying mode after being turned on, the set temperature (such as the user set temperature T 设 ) of the air conditioner is obtained, the set wind level (such as the user set running wind level S 档 ) of the indoor fan is obtained; the running time (such as the air conditioner running time T 运行 ) of the air conditioner is obtained, the indoor environment temperature (such as the indoor environment temperature T 环 ) of the air conditioner is obtained; and the drainage amount of the condensed water generated by the indoor heat exchanger is obtained, which is recorded as the drainage amount (such as the indoor heat exchanger drainage amount P) of the air conditioner. Specifically, the drainage amount of the condensed water generated by the indoor heat exchanger can be obtained by detecting the drainage amount of the condensed water in the drainage passage of the indoor unit by the drainage amount detection device as the drainage amount of the condensed water generated on the indoor heat exchanger.

[0038] At step S120, in the case that the running time of the air conditioner reaches a preset running time, the water amount of the indoor heat exchanger is determined according to the running time of the air conditioner and the drainage amount of the air conditioner; wherein the preset running time is, for example, a preset time T 预设1 .

[0039] At step S130, it is determined whether the water amount of the indoor heat exchanger is less than a preset first water amount.

[0040] At step S140, if it is determined that the water amount of the indoor heat exchanger is less than the preset first water amount, the air conditioner is controlled to maintain the current state and then returns to continue to determine the water amount of the indoor heat exchanger according to the running time of the air conditioner and the drainage amount of the air conditioner in the case that the running time of the air conditioner reaches the preset running time again.

[0041] At step S150, if it is determined that the water hanging amount of the indoor heat exchanger is greater than or equal to the preset first water amount, the running frequency of the compressor is adjusted and the running wind level of the indoor fan is adjusted according to the water hanging amount of the indoor heat exchanger and the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, so as to adjust the water hanging amount of the indoor heat exchanger, specifically, to reduce the water hanging amount of the indoor heat exchanger of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the energy saving performance in use; and then, it is returned to continue to determine the water hanging amount of the indoor heat exchanger according to the running time of the air conditioner and the drainage amount of the air conditioner in the case that the running time of the air conditioner reaches the preset running time, so as to realize the dynamic cycle adjustment of the water hanging amount of the indoor heat exchanger.

[0042] The scheme of the present application adds a drainage amount detection device and an operation control logic on the basis of the use of an air conditioner (such as a user's home split variable frequency air conditioner), detects the condensate water amount of the indoor heat exchanger of the air conditioner, determines the water hanging amount of the indoor heat exchanger, and adjusts the running state of the air conditioner according to the difference between the indoor environment temperature and the set temperature, so as to reduce the water hanging amount of the indoor heat exchanger of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the energy saving performance in use.

[0043] In some embodiments, the determination of the water hanging amount of the indoor heat exchanger according to the running time of the air conditioner and the drainage amount of the air conditioner in the case that the running time of the air conditioner reaches the preset running time in step S120 includes any one of the following determination cases:

[0044] The first determination case is to accumulate the drainage amount of the air conditioner obtained in the running time of the air conditioner to obtain the accumulated drainage amount of the air conditioner, and to use the accumulated drainage amount of the air conditioner to represent the water hanging amount of the indoor heat exchanger. In the scheme of the present application, the running state of the air conditioner can be adjusted according to the accumulated drainage amount in the time period in which the running time of the air conditioner reaches the preset running time.

[0045] The second determination case is to accumulate the drainage amount of the air conditioner obtained in the running time of the air conditioner to obtain the accumulated drainage amount of the air conditioner, and to determine the drainage rate of the air conditioner by using the ratio of the accumulated drainage amount of the air conditioner to the running time of the air conditioner, and to use the drainage rate of the air conditioner to represent the water hanging amount of the indoor heat exchanger. In the scheme of the present application, the drainage amount speed can also be used as a criterion to adjust the running state of the air conditioner according to the speed. The drainage amount speed = drainage amount / drainage time, and the water hanging amount of the indoor heat exchanger of the air conditioner is determined according to the drainage amount speed, and the determination method is similar to the determination method based on the accumulated drainage amount P1.

[0046] In the scheme of the present application, the condensate water amount of the indoor heat exchanger of the air conditioner is detected to more accurately determine whether the indoor heat exchanger is attached with too much water to affect the refrigeration or dehumidification effect. The condensate water amount of the indoor heat exchanger of the air conditioner is detected to determine the condensate water amount of the indoor heat exchanger, thereby solving the problem that the split indoor unit of the air conditioner cannot effectively determine the condensate water amount of the indoor heat exchanger.

[0047] In some embodiments, in the case where the water amount attached to the indoor heat exchanger in step S150 is greater than or equal to the preset first water amount, the running frequency of the compressor and the running wind level of the indoor fan are adjusted according to the water amount attached to the indoor heat exchanger and the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, to adjust the water amount attached to the indoor heat exchanger. For details, see the following exemplary description.

[0048] The following will be described in combination with Figure 2 FIG. 1 shows an embodiment flowchart of the method of the present application for adjusting the water amount attached to the indoor heat exchanger, to further illustrate the specific process of adjusting the water amount attached to the indoor heat exchanger in step S120, which includes steps S210 to S230.

[0049] In step S210, in the case where the water amount attached to the indoor heat exchanger is greater than or equal to the preset first water amount, it is determined whether the water amount attached to the indoor heat exchanger is less than the preset second water amount. In the case where the water amount attached to the indoor heat exchanger is indicated by the cumulative drainage amount table of the air conditioner, the preset first water amount is, for example, the preset drainage amount P 预设1 , and the preset second water amount is, for example, the preset drainage amount P 预设2 .

[0050] In step S220, in the case where the water amount attached to the indoor heat exchanger is greater than or equal to the preset first water amount, if it is determined that the water amount attached to the indoor heat exchanger is less than the preset second water amount, the running frequency of the compressor and the running wind level of the indoor fan are adjusted according to the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, to perform first adjustment on the water amount attached to the indoor heat exchanger.

[0051] In step S230, in the case where the water amount attached to the indoor heat exchanger is greater than or equal to the preset first water amount, if it is determined that the water amount attached to the indoor heat exchanger is greater than or equal to the preset second water amount, the running frequency of the compressor and the running wind level of the indoor fan are adjusted according to the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, to perform second adjustment on the water amount attached to the indoor heat exchanger.

[0052] Figure 6 FIG. 1 shows an embodiment flowchart of the method of the present application for adjusting the water amount attached to the indoor heat exchanger, to further illustrate the specific process of adjusting the water amount attached to the indoor heat exchanger in step S120, which includes steps S210 to S230.档 indicates the remote control setting start-up gear; T 设 indicates the remote control start-up setting temperature; T 运行 indicates the air conditioner running time; T 预设1 indicates the preset time; P 预设1 , P 预设2 , P 预设3 all indicate information indicating the preset drainage volume; T1, T2, T3, T4, and the like indicate preset times; P indicates the air conditioner drainage volume information; ΔT indicates the temperature difference; T 环 indicates the indoor environment temperature. For example: T 预设1 is 1h, P 预设1 is 500ml, P 预设2 is 1000ml, P 预设3 is 1500ml, T1 is 15min, T2 is 30min, T3 is 25min, and T4 is 40min. Among them, when the temperature difference ΔT is within the preset range value and the drainage volume is large, the time of running according to this logic needs to be longer to ensure that the generation of the air conditioner condensate water can be sufficiently reduced, so the preset time T3 is longer than the preset time T1; when the same interval of the drainage volume and the temperature difference ΔT are not within the preset range value, the time of running according to this logic is appropriately lengthened while ensuring the refrigeration effect to ensure that the generation of the air conditioner condensate water can be sufficiently reduced, so the preset time T2 is longer than the preset time T1 and the preset time T4 is longer than the preset time T3. As shown in Figure 6 , the running control method of the variable frequency air conditioner comprises:

[0053] Step 1, when the user uses the air conditioner to run for refrigeration or dehumidification, the user setting running air gear S 档 , the user setting temperature T 设 , the indoor environment temperature T 环 , the air conditioner running time T 运行 , the indoor heat exchanger drainage volume P of the air conditioner is detected and recorded, and then step 2 is executed.

[0054] Step 2, when the air conditioner running time reaches the preset time T 预设1 , the cumulative drainage volume P1 of the air conditioner in this time period (i.e. the time period of the air conditioner running time) is recorded, and whether the cumulative drainage volume P1 of the air conditioner in this time period is lower than the preset drainage volume P 预设1 is judged: if yes, the air conditioner maintains the original state running, and returns to step 2, and when the air conditioner running time reaches the preset time T 预设1 again, the judgment is performed again; otherwise, step 3 is executed.

[0055] In step 2, when the cumulative drainage volume P1 of the air conditioner in this time period is less than the preset drainage volume P 预设1During this time, the air conditioner maintains its original operating logic. During the cooling process, the indoor heat exchanger will always produce condensate. The amount of condensate will vary depending on the air conditioner's operating state. When there is less condensate, there will be less water buildup on the indoor heat exchanger, requiring no additional treatment.

[0056] Step 3: Determine whether the cumulative drainage volume P1 of the air conditioner during this period is within the preset drainage volume P. 预设1 With preset drainage volume P 预设2 If the range is within the specified range, then proceed to step 4 to make a first adjustment to the water flow of the indoor heat exchanger; otherwise, proceed to step 5 to make a second adjustment to the water flow of the indoor heat exchanger.

[0057] In the present invention, based on the basic functions of an air conditioner, a drainage volume detection device is added at the connection between the drain hole and the drain pipe of the indoor unit. The drainage volume detection device detects the amount of condenser water drained during the cooling or dehumidification process of the air conditioner, determines the water accumulation in the indoor heat exchanger, and at the same time, by detecting changes in indoor ambient temperature, the operating status of the air conditioner is adjusted according to the difference between the indoor ambient temperature and the set temperature, thereby reducing the amount of water accumulation in the indoor heat exchanger and improving the operating efficiency of the air conditioner.

[0058] In some embodiments, when the water volume of the indoor heat exchanger is greater than or equal to a preset first water volume and less than a preset second water volume in step S220, the operating frequency of the compressor and the operating speed of the indoor fan are adjusted according to the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner to make a first adjustment to the water volume of the indoor heat exchanger. For details, please refer to the following exemplary description.

[0059] The following is combined with Figure 3 The schematic diagram shown is a flowchart of an embodiment of the method of the present invention for making a first adjustment to the water volume of the indoor heat exchanger. It further illustrates the specific process of making a first adjustment to the water volume of the indoor heat exchanger in step S220, including steps S310 to S340.

[0060] Step S310: Determine the temperature difference between the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, and record it as the indoor temperature difference of the air conditioner; wherein, the indoor temperature difference of the air conditioner, such as the indoor ambient temperature T... 环 With the set temperature T 设 The difference ΔT.

[0061] Step S320: Determine whether the indoor temperature difference of the air conditioner is within the preset temperature range.

[0062] Step S330, if it is determined that the indoor temperature difference of the air conditioner is within the preset temperature range, the running frequency of the compressor is reduced by a first set frequency based on the current value, and the running wind level of the indoor fan is increased, and then the air conditioner is operated according to the current adjusted running logic for a preset first time, and then the running logic before adjustment is restored. Here, the running wind level of the indoor fan can be increased specifically as follows: if the set level of the running wind level of the indoor fan is greater than or equal to a preset maximum wind level, the running wind level of the indoor fan is maintained at the set level; if the set level of the running wind level of the indoor fan is less than the preset maximum wind level, the current value of the running wind level of the indoor fan is increased by one level. Wherein, the first set frequency is ΔF1, and the preset first time is T1.

[0063] Step S340, if it is determined that the indoor temperature difference of the air conditioner is not within the preset temperature range, the running frequency of the compressor is reduced by a second set frequency based on the current value, and the running wind level of the indoor fan is increased, and then the air conditioner is operated according to the current adjusted running logic for a preset second time, and then the running logic before adjustment is restored. Here, the running wind level of the indoor fan can be increased specifically as follows: if the set level of the running wind level of the indoor fan is greater than or equal to a preset maximum wind level, the running wind level of the indoor fan is maintained at the set level; if the set level of the running wind level of the indoor fan is less than the preset maximum wind level, the current value of the running wind level of the indoor fan is increased by one level. Wherein, the first set frequency is greater than the second set frequency, the second set frequency is ΔF2, and the preset second time is T2. Wherein, the set maximum wind level is a high wind level or an ultra-high wind level.

[0064] As shown in Figure 6 , the running control method of the variable frequency air conditioner further comprises: step 4, when the cumulative drainage amount P1 of the air conditioner in the time period is within the interval range between the preset drainage amount P 预设1 and the preset drainage amount P 预设2 , record the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设 , compare the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设 with the preset temperature range, execute step 41 or step 42 according to the comparison result, and then execute step 6.

[0065] Step 41, if the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设If the difference ΔT between the indoor environment temperature T and the set temperature Tset is within the preset temperature range, the running frequency of the compressor is reduced by ΔF1 based on the current running frequency of the compressor in the air conditioner, and the running wind level of the indoor fan is adjusted. For details, see steps 411 and 412. For example, ΔT can be preset as 3℃, at this time, the room temperature is close to the user set temperature, and the user's demand for the air conditioner is reduced. ΔF1 can be 14 Hz, and the reduced running frequency cannot be lower than the minimum frequency allowed by the air conditioner.

[0066] Step 411, if the original set wind level of the indoor unit is at a high wind level or a super strong wind level, the running wind level of the indoor fan is controlled to maintain this level, the state runs for a time T1 (such as 15 min), and then step 6 is performed.

[0067] Step 412, if the original set wind level of the indoor unit is at the remaining levels, the running wind level of the indoor fan is controlled to be increased by one level, the generation of condensate water of the air conditioner is reduced, the state runs for a preset time T1, and after the preset time T1 is met, the original running logic is run (i.e., step 6 is performed).

[0068] Step 42, if the difference ΔT between the indoor environment temperature T and the set temperature Tset exceeds the preset temperature range, the running frequency of the compressor is reduced by ΔF2 based on the current running frequency of the compressor in the air conditioner, and the running wind level of the indoor fan is adjusted. For details, see steps 421 and 422. For example, ΔF2 can be 8 Hz, and the reduced running frequency cannot be lower than the minimum frequency allowed by the air conditioner.

[0069] Step 421, if the original set wind level of the indoor unit is at a high wind level or a super strong wind level, the running wind level of the indoor fan is controlled to maintain this level, the state runs for a time T2 (such as 30 min), and then step 6 is performed.

[0070] Step 422, if the original set wind level of the indoor unit is at the remaining levels, the running wind level of the indoor fan is controlled to be increased by one level, the generation of condensate water is reduced while the refrigeration effect is ensured, the state runs for a preset time T2, and after the preset time T2 is met, the original running logic is run (i.e., step 6 is performed).

[0071] In this invention, by adding this control logic, the operating parameters of the air conditioner are adjusted differently while ensuring user comfort. For example, if the user sets the temperature to 20°C, and the indoor ambient temperature drops to 23°C or below, the user's cooling demand is relatively reduced. In this case, the compressor's operating frequency ΔF1 is reduced, and the indoor fan's operating speed is increased to improve airflow. This raises the evaporation temperature of the indoor heat exchanger, reducing condensation and removing excess water from the heat exchanger. Conversely, if the user sets the temperature to 20°C, and the indoor ambient temperature drops to 25°C, the user still needs cooling. In this case, the compressor's operating frequency ΔF2 is appropriately reduced, and the indoor fan's operating speed is increased to improve airflow. This reduces condensation in the heat exchanger while maintaining cooling performance. Typically, the reduction ΔF1 is greater than ΔF2.

[0072] In some embodiments, in step S230, when the water volume of the indoor heat exchanger is greater than or equal to a preset second water volume, the operating frequency of the compressor is adjusted according to the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, and the operating speed of the indoor fan is adjusted to make a second adjustment to the water volume of the indoor heat exchanger. For details, please refer to the following exemplary description.

[0073] The following is combined with Figure 4 The schematic diagram shown is a flowchart of an embodiment of the method of the present invention for making a second adjustment to the water volume of the indoor heat exchanger. It further illustrates the specific process of making a second adjustment to the water volume of the indoor heat exchanger in step S230, including steps S410 to S440.

[0074] Step S410: Determine the temperature difference between the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, and record it as the indoor temperature difference of the air conditioner; wherein, the indoor temperature difference of the air conditioner, such as the indoor ambient temperature T... 环 With the set temperature T 设 The difference ΔT.

[0075] Step S420: Determine whether the indoor temperature difference of the air conditioner is within the preset temperature range.

[0076] Step S430, if it is determined that the indoor temperature difference of the air conditioner is within the preset temperature range, the operating frequency of the compressor is reduced to the preset minimum frequency based on the current value, the operating wind level of the indoor fan is increased, and then the air conditioner is operated according to the current adjusted operating logic for a preset third time and then returns to the operating logic before adjustment. Here, the operating wind level of the indoor fan can be increased in particular as follows: if the set level of the operating wind level of the indoor fan is greater than or equal to the preset maximum wind level, the operating wind level of the indoor fan is maintained at the set level; if the set level of the operating wind level of the indoor fan is less than the preset maximum wind level, the current value of the operating wind level of the indoor fan is increased by one level. The preset third time is, for example, the preset time T3.

[0077] Step S440, if it is determined that the indoor temperature difference of the air conditioner is not within the preset temperature range, the operating frequency of the compressor is reduced by a third set frequency based on the current value, the operating wind level of the indoor fan is increased, and then the air conditioner is operated according to the current adjusted operating logic for a preset fourth time and then returns to the operating logic before adjustment. Here, the operating wind level of the indoor fan can be increased in particular as follows: if the set level of the operating wind level of the indoor fan is greater than or equal to the preset maximum wind level, the operating wind level of the indoor fan is maintained at the set level; if the set level of the operating wind level of the indoor fan is less than the preset maximum wind level, the current value of the operating wind level of the indoor fan is increased by one level. The third set frequency is greater than the second set frequency, the third set frequency is, for example, the frequency ΔF3, and the preset fourth time is, for example, the preset time T4. Since the evaporator is more likely to be waterlogged in this interval, the third set frequency should be greater than the second set frequency, for example, ΔF2 is 8 Hz and ΔF3 is 12 Hz, which can more effectively reduce the waterlogging of the evaporator, and the reduced operating frequency cannot be lower than the minimum operating frequency allowed by the air conditioner.

[0078] As shown in FIG. 5, the operating control method of the variable frequency air conditioner further includes the following steps. Figure 6 Step 5: when the cumulative drainage amount P1 of the air conditioner in this time period exceeds the preset drainage amount P 预设2 , the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设 is recorded, the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设 is compared with the preset temperature range, step 51 or step 52 is executed according to the comparison result, and then step 6 is executed.

[0079] Step 51: if the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设If the difference ΔT between the indoor environment temperature T and the set temperature T is within the preset temperature range, the running frequency of the compressor in the air conditioner is reduced to the lowest frequency, and the running wind level of the indoor fan is adjusted, see steps 511 and 512.

[0080] Step 511, if the original set wind level of the indoor unit is at a high wind level or an ultra-high wind level, the running wind level of the indoor fan is controlled to maintain this level, and the air conditioner is run for a preset time T3 in this state, and after the preset time T3 is met, the air conditioner is run according to the original running logic.

[0081] Step 512, if the original set wind level of the indoor unit is at any other level, the running wind level of the indoor fan is controlled to be increased by one level, the air conditioner is run for a time T3 (such as 25 minutes) in this state, the generation of condensate water in the air conditioner is reduced, and then step 6 is performed.

[0082] Step 52, if the indoor environment temperature T 环 is greater than the set temperature T 设 by a preset temperature range, the running frequency of the compressor in the air conditioner is appropriately reduced by ΔF3 based on the current running frequency of the compressor, and the running wind level of the indoor fan is adjusted, see steps 521 and 522.

[0083] Step 521, if the original set wind level of the indoor unit is at a high wind level or an ultra-high wind level, the running wind level of the indoor fan is controlled to maintain this level, the air conditioner is run for a time T4 (such as 40 minutes) in this state, and then step 6 is performed.

[0084] Step 522, if the original set wind level of the indoor unit is at any other level, the running wind level of the indoor fan is controlled to be increased by one level, the generation of condensate water is reduced while the refrigeration effect is ensured, the air conditioner is run for a preset time T4 in this state, and after the preset time T4 is met, the air conditioner is run according to the original running logic (i.e., step 6 is performed).

[0085] In the scheme of the application, by adding this control logic, the running parameters are adjusted differently while ensuring the comfort of the air conditioner. For example, when the user sets the temperature to 20℃, the indoor environment temperature is reduced to 23℃ or below, at this time, the user's demand for refrigeration is relatively reduced, but at this time, the indoor heat exchanger is seriously water-attached, and the running frequency of the compressor in the air conditioner needs to be reduced to the lowest frequency, and at the same time, the air volume of the indoor fan is increased to quickly reduce the amount of water attached to the indoor heat exchanger.

[0086] Step 6, when the air conditioner is run according to the original running logic, return to step 2, and when the running time of the air conditioner again meets T 预设1 , record the drainage amount information, and adjust the running state of the air conditioner.

[0087] In the scheme of the present application, new air conditioner operation logic is added, appropriate operation logic is selected, condensate water adhesion of the indoor heat exchanger is reduced, and air conditioner operation efficiency is improved; wherein the new operation logic detects the condensate water amount in the air conditioner operation process, detects the use environment, adjusts the air conditioner operation state, reduces the condensate water amount, and improves the operation efficiency.

[0088] In the scheme of the present application, the drainage amount speed can also be used as a distinction, and the air conditioner operation state is adjusted according to the speed. 环 The difference between the indoor environment temperature T 设 and the set temperature T

[0089] In some embodiments, the step of increasing the operation wind level of the indoor fan in any one of steps S330, S340, S430, and S440 includes any one of the following increasing cases.

[0090] The first increasing case: if the set level of the operation wind level of the indoor fan is greater than or equal to a preset maximum wind level, the set level of the operation wind level of the indoor fan is maintained, and specific examples can be found in steps 411, 421, 511, and 521.

[0091] The second increasing case: if the set level of the operation wind level of the indoor fan is less than the preset maximum wind level, the current value of the operation wind level of the indoor fan is increased by one level, and specific examples can be found in steps 412, 422, 512, and 522.

[0092] In the scheme of the present application, by determining the condensate water adhesion of the indoor heat exchanger and comparing the difference between the real-time environment temperature and the user set temperature, the operation frequency and operation level of the air conditioner are adjusted, the condensate water adhesion of the indoor heat exchanger is reduced, the condensate water adhesion amount and the dust adhesion amount of the indoor heat exchanger are effectively reduced during the air conditioner cooling or dehumidifying operation process, the cooling effect of the air conditioner is improved, and the use comfort of the air conditioner is improved.

[0093] The technical scheme of the embodiment is adopted, the drainage amount detection device is arranged at the connection position of the drainage hole of the indoor unit and the drainage pipe, the drainage amount detection device is used to detect the drainage amount of the condensed water of the indoor unit, the accumulated drainage amount of the indoor unit or the drainage speed of the indoor unit is determined according to the detected drainage amount of the condensed water of the indoor unit, the water hanging amount of the indoor heat exchanger is determined according to the accumulated drainage amount of the indoor unit or the drainage speed of the indoor unit, the operation state of the compressor and the indoor fan is adjusted in combination with the difference between the indoor environment temperature and the set temperature, so as to adjust the operation logic of the air conditioner and control the water hanging amount of the indoor heat exchanger, so that the water hanging state of the indoor heat exchanger is detected, and the operation state of the air conditioner is adjusted in combination with the difference between the indoor environment temperature and the set temperature, so as to reduce the water hanging amount of the indoor heat exchanger and improve the operation efficiency of the air conditioner.

[0094] According to the embodiment of the present application, a control device of an air conditioner corresponding to the control method of the air conditioner is also provided. Referring to Figure 5 the structural schematic diagram of an embodiment of the device of the present application is shown. The air conditioner has an outdoor unit and an indoor unit, the outdoor unit has a compressor, and the indoor unit has an indoor heat exchanger and an indoor fan; a drainage amount detection device is arranged in the drainage passage of the indoor unit, which is used to detect the drainage amount of the condensed water in the drainage passage of the indoor unit as the drainage amount of the condensed water generated on the indoor heat exchanger; in the scheme of the present application, as Figure 5 shown, the control device of the air conditioner comprises an acquisition unit 102 and a control unit 104.

[0095] The acquisition unit 102 is configured to, in the case that the air conditioner runs in a refrigeration mode or a dehumidification mode after starting, acquire the set temperature (such as the user set temperature T 设 ) of the air conditioner, acquire the set wind gear (such as the user set operation wind gear S 档 ) of the indoor fan, acquire the operation time (such as the air conditioner operation time T 运行 ) of the air conditioner, acquire the indoor environment temperature (such as the indoor environment temperature T 环 ) of the air conditioner, and acquire the drainage amount of the condensed water generated by the indoor heat exchanger, which is recorded as the drainage amount (such as the indoor heat exchanger drainage amount P of the air conditioner) of the air conditioner. Specifically, the drainage amount of the condensed water generated by the indoor heat exchanger can be the drainage amount of the condensed water in the drainage passage of the indoor unit detected by the drainage amount detection device, which is recorded as the drainage amount of the condensed water generated on the indoor heat exchanger. The specific functions and processes of the acquisition unit 102 are described in step S110.

[0096] The control unit 104 is configured to determine the water hanging amount of the indoor heat exchanger according to the running time of the air conditioner and the drainage amount of the air conditioner in a case where it is determined that the running time of the air conditioner reaches a preset running time, wherein the preset running time is, for example, a preset time T 预设1 The specific functions and processes of the control unit 104 are described with reference to step S120.

[0097] The control unit 104 is further configured to determine whether the water hanging amount of the indoor heat exchanger is less than a preset first water amount. The specific functions and processes of the control unit 104 are also described with reference to step S130.

[0098] The control unit 104 is further configured to control the air conditioner to maintain the current state running if it is determined that the water hanging amount of the indoor heat exchanger is less than the preset first water amount, and then return to continue to determine the water hanging amount of the indoor heat exchanger according to the running time of the air conditioner and the drainage amount of the air conditioner in a case where it is determined that the running time of the air conditioner reaches the preset running time again. The specific functions and processes of the control unit 104 are also described with reference to step S140.

[0099] The control unit 104 is further configured to adjust the running frequency of the compressor and the running wind grade of the indoor fan to adjust the water hanging amount of the indoor heat exchanger according to the water hanging amount of the indoor heat exchanger and the difference between the indoor environment temperature of the air conditioner and the set temperature of the air conditioner if it is determined that the water hanging amount of the indoor heat exchanger is greater than or equal to the preset first water amount, specifically to reduce the water hanging amount of the indoor heat exchanger of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the energy saving performance in use; and then return to continue to determine the water hanging amount of the indoor heat exchanger according to the running time of the air conditioner and the drainage amount of the air conditioner in a case where it is determined that the running time of the air conditioner reaches the preset running time again, to realize dynamic cyclic adjustment of the water hanging amount of the indoor heat exchanger. The specific functions and processes of the control unit 104 are also described with reference to step S150.

[0100] The scheme of the present application adds a drainage amount detection device and a running control logic on the basis of the use of an air conditioner (such as a user's home split variable frequency air conditioner), detects the condensate water amount of the indoor heat exchanger of the air conditioner, determines the water hanging amount of the indoor heat exchanger, and adjusts the running state of the air conditioner in combination with the difference between the indoor environment temperature and the set temperature, to reduce the water hanging amount of the indoor heat exchanger of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the energy saving performance in use.

[0101] In some embodiments, the control unit 104, in a case where the running time of the air conditioner reaches a preset running time, determines the water hanging amount of the indoor heat exchanger according to the running time of the air conditioner and the water discharge amount of the air conditioner, including any of the following determination cases:

[0102] The first determination case: the control unit 104 is specifically further configured to accumulate the water discharge amount of the air conditioner obtained within the running time of the air conditioner to obtain the accumulated water discharge amount of the air conditioner; and use the accumulated water discharge amount of the air conditioner to represent the water hanging amount of the indoor heat exchanger. In the scheme of the present application, the air conditioner running state can be adjusted according to the accumulated water discharge amount within the time period when the running time of the air conditioner reaches the preset running time.

[0103] The second determination case: the control unit 104 is specifically further configured to accumulate the water discharge amount of the air conditioner obtained within the running time of the air conditioner to obtain the accumulated water discharge amount of the air conditioner; and determine the ratio of the accumulated water discharge amount of the air conditioner to the running time of the air conditioner as the water discharge rate of the air conditioner; and use the water discharge rate of the air conditioner to represent the water hanging amount of the indoor heat exchanger. In the scheme of the present application, the water discharge amount speed can also be used as a criterion to adjust the air conditioner running state according to the speed. Wherein, the water discharge amount speed = water discharge amount / water discharge time, the water hanging condition of the indoor heat exchanger of the air conditioner is determined according to the water discharge amount speed, and the determination method is similar to the determination method based on the accumulated water discharge amount P1.

[0104] In the scheme of the present application, by detecting the condensate water amount of the indoor heat exchanger of the air conditioner, it is more accurate to determine whether the indoor heat exchanger is attached with too much water to affect the refrigeration or dehumidification effect; by detecting the condensate water amount of the indoor heat exchanger of the air conditioner, the condensate water amount of the indoor heat exchanger is determined, and the problem that the split indoor unit of the air conditioner cannot effectively determine the condensate water amount of the indoor heat exchanger is solved.

[0105] In some embodiments, in a case where the water hanging amount of the indoor heat exchanger is greater than or equal to a preset first water amount, the control unit 104 adjusts the running frequency of the compressor and adjusts the running wind gear of the indoor fan according to the water hanging amount of the indoor heat exchanger and the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, to adjust the water hanging amount of the indoor heat exchanger, including:

[0106] The control unit 104 is specifically further configured to, in a case where the water hanging amount of the indoor heat exchanger is greater than or equal to a preset first water amount, determine whether the water hanging amount of the indoor heat exchanger is less than a preset second water amount; wherein, in a case where the water hanging amount of the indoor heat exchanger is represented by the accumulated water discharge amount of the air conditioner, the preset first water amount is like a preset water discharge amount P预设1 , the preset second water amount is, for example, a preset drainage amount P 预设2 The specific functions and processes of the control unit 104 are also described in step S210.

[0107] The control unit 104 is specifically configured to, in the case where the water hanging amount of the indoor heat exchanger is greater than or equal to the preset first water amount, if it is determined that the water hanging amount of the indoor heat exchanger is less than the preset second water amount, adjust the operating frequency of the compressor and adjust the operating wind level of the indoor fan according to the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, to perform first adjustment on the water hanging amount of the indoor heat exchanger. The specific functions and processes of the control unit 104 are also described in step S220.

[0108] The control unit 104 is specifically configured to, in the case where the water hanging amount of the indoor heat exchanger is greater than or equal to the preset first water amount, if it is determined that the water hanging amount of the indoor heat exchanger is greater than or equal to the preset second water amount, adjust the operating frequency of the compressor and adjust the operating wind level of the indoor fan according to the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, to perform second adjustment on the water hanging amount of the indoor heat exchanger. The specific functions and processes of the control unit 104 are also described in step S230.

[0109] Figure 6 is a flowchart of an embodiment of the operation control method of the variable frequency air conditioner. In the following description, S 档 represents the remote control set start-up level; T 设 represents the remote control set start-up temperature; T 运行 represents the air conditioner operating time; T 预设1 represents the preset time; P 预设1 , P 预设2 , P 预设3 all represent information of the preset drainage amount; T1, T2, T3, T4, etc. all represent preset times; P represents the air conditioner drainage amount information; ΔT represents the temperature difference; T 环 represents the indoor environment temperature. As shown in Figure 6 , the operation control method of the variable frequency air conditioner comprises:

[0110] Step 1, when the user uses the air conditioner to run in cooling or dehumidifying mode, record the user set operating wind level S 档 , the user set temperature T 设 , record the indoor environment temperature T 环 , record the air conditioner operating time T 运行 , detect and record the indoor heat exchanger drainage amount P of the air conditioner, and record the subsequent step 2.

[0111] Step 2, when the air conditioner running time reaches the preset time T 预设1 , record the cumulative drainage amount P1 of the air conditioner in this time period (i.e. the time period of the air conditioner running time), and determine whether the cumulative drainage amount P1 of the air conditioner in this time period is lower than the preset drainage amount P 预设1 : if yes, the air conditioner maintains the original state and returns to step 2 to determine again when the air conditioner running time reaches the preset time T 预设1 ; otherwise, step 3 is performed.

[0112] In step 2, when the cumulative drainage amount P1 of the air conditioner in this time period is less than the preset drainage amount P 预设1 , the air conditioner maintains the original operation logic. During the refrigeration process of the air conditioner, the indoor heat exchanger will always produce condensate water, and the amount of condensate water will be different in different states of the air conditioner. When the amount of condensate water is relatively small, the amount of water hanging on the indoor heat exchanger will also be relatively small, and no additional treatment is required.

[0113] Step 3, determine whether the cumulative drainage amount P1 of the air conditioner in this time period is within the interval range between the preset drainage amount P 预设1 and the preset drainage amount P 预设2 : if yes, step 4 is performed to make a first adjustment to the amount of water hanging on the indoor heat exchanger; otherwise, step 5 is performed to make a second adjustment to the amount of water hanging on the indoor heat exchanger.

[0114] In the scheme of the present application, on the basis of the basic function of the air conditioner, a drainage amount detection device is newly added at the connection between the drainage hole of the indoor unit and the drainage pipe. The drainage amount detection device detects the drainage amount of the condenser water during the refrigeration or dehumidification process of the air conditioner, determines the water hanging condition of the indoor heat exchanger, and simultaneously detects the change of the indoor environment temperature, adjusts the operation state of the air conditioner according to the difference between the indoor environment temperature and the set temperature, reduces the amount of water hanging on the indoor heat exchanger, and improves the operation efficiency of the air conditioner.

[0115] In some embodiments, the control unit 104, in the case that the amount of water hanging on the indoor heat exchanger is greater than or equal to a preset first water amount and less than a preset second water amount, adjusts the operation frequency of the compressor and the operation wind gear of the indoor fan according to the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, to make a first adjustment to the amount of water hanging on the indoor heat exchanger, including:

[0116] The control unit 104 is specifically configured to determine the temperature difference between the indoor environment temperature T 环 of the air conditioner and the set temperature T 设The difference ΔT. For the specific functions and processing of this control unit 104, please refer to step S310.

[0117] The control unit 104 is further configured to determine whether the indoor temperature difference of the air conditioner is within a preset temperature range. The specific functions and processing of the control unit 104 are further described in step S320.

[0118] The control unit 104 is further configured to, if it is determined that the indoor temperature difference of the air conditioner is within a preset temperature range, reduce the operating frequency of the compressor by a first preset frequency based on the current value, increase the operating speed of the indoor fan, and then allow the air conditioner to operate according to the currently adjusted operating logic for a preset first time before resuming the operating logic before adjustment. Specifically, increasing the operating speed of the indoor fan can be achieved as follows: if the set speed of the indoor fan is greater than or equal to the preset maximum speed, the operating speed of the indoor fan is maintained at the set speed; if the set speed of the indoor fan is less than the preset maximum speed, the current value of the indoor fan's operating speed is increased by one level. The first preset frequency is such as frequency ΔF1, and the preset first time is such as preset time T1. The specific functions and processing of this control unit 104 are further described in step S330.

[0119] The control unit 104 is further configured to, if it is determined that the indoor temperature difference of the air conditioner is not within the preset temperature range, reduce the operating frequency of the compressor by a second preset frequency based on the current value, increase the operating speed of the indoor fan, and then allow the air conditioner to run according to the currently adjusted operating logic for a preset second time before resuming the operating logic before adjustment. Here, increasing the operating speed of the indoor fan can specifically be: if the set level of the indoor fan's operating speed is greater than or equal to the preset maximum speed, then control the indoor fan's operating speed to maintain the set level; if the set level of the indoor fan's operating speed is less than the preset maximum speed, then control the current value of the indoor fan's operating speed to increase by one level. Wherein, the first preset frequency is greater than the second preset frequency, the second preset frequency is such as frequency ΔF2, and the preset second time is such as preset time T2. The specific functions and processing of this control unit 104 are also described in step S340.

[0120] like Figure 6 As shown, the operation control method of the inverter air conditioner also includes: Step 4, when the cumulative drainage volume P1 of the air conditioner during this time period is at the preset drainage volume P 预设1 With preset drainage volume P 预设2 When the temperature falls within the range between these two values, record the indoor ambient temperature T. 环 With the set temperature T 设 The difference ΔT, which represents the indoor ambient temperature T环 the difference ΔT between the indoor environment temperature T 设 is compared with the preset temperature range, and step 41 or step 42 is executed according to the comparison result, and then step 6 is executed.

[0121] Step 41, if the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设 is within the preset temperature range, the operating frequency ΔF1 of the compressor is appropriately reduced on the basis of the current operating frequency of the compressor in the air conditioner, and the operating wind level of the indoor fan is adjusted, which is specifically described in steps 411 and 412.

[0122] Step 411, if the original set wind level of the indoor unit is at a high wind level or an extra-high wind level, the operating wind level of the indoor fan is controlled to maintain this level, and then step 6 is executed.

[0123] Step 412, if the original set wind level of the indoor unit is at any other level, the operating wind level of the indoor fan is controlled to be increased by one level, the generation of condensate water of the air conditioner is reduced, and the air conditioner is operated in this state for a preset time T1, and after the preset time T1 is met, the air conditioner is operated according to the original operating logic (i.e., step 6 is executed).

[0124] Step 42, if the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设 is beyond the preset temperature range, the operating frequency ΔF2 of the compressor is appropriately reduced on the basis of the current operating frequency of the compressor in the air conditioner, and the operating wind level of the indoor fan is adjusted, which is specifically described in steps 421 and 422.

[0125] Step 421, if the original set wind level of the indoor unit is at a high wind level or an extra-high wind level, the operating wind level of the indoor fan is controlled to maintain this level, and then step 6 is executed.

[0126] Step 422, if the original set wind level of the indoor unit is at any other level, the operating wind level of the indoor fan is controlled to be increased by one level, the generation of condensate water is reduced while the refrigeration effect is ensured, the air conditioner is operated in this state for a preset time T2, and after the preset time T2 is met, the air conditioner is operated according to the original operating logic (i.e., step 6 is executed).

[0127] In the scheme of the present application, by adding this control logic, while ensuring the comfort of the air conditioner, the operating parameters of the air conditioner are adjusted differently. For example, the user sets the temperature to 20℃, when the indoor environment temperature is reduced to 23℃ and below, at this time the user's cooling demand is relatively reduced, at this time reduce the operating frequency of the compressor ΔF1, improve the gear of the indoor fan operating wind, improve the air volume, can improve the evaporation temperature of the indoor heat exchanger, reduce the generation of condensate water, at the same time, by increasing the air volume, the attached water amount of the indoor heat exchanger is taken away. For example, the user sets the temperature to 20℃, when the indoor environment temperature is reduced to 25℃, at this time the user still has a cooling demand, at this time appropriately reduce the operating frequency of the compressor ΔF2, improve the gear of the indoor fan operating wind, improve the air volume, reduce the generation of condensate water of the indoor heat exchanger while ensuring the cooling effect. Usually, the reduction amplitude ΔF1 is higher than ΔF2.

[0128] In some embodiments, the control unit 104, in the case that the water hanging amount of the indoor heat exchanger is greater than or equal to a preset second water amount, adjusts the operating frequency of the compressor and adjusts the operating wind gear of the indoor fan according to the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, to make a second adjustment to the water hanging amount of the indoor heat exchanger, including:

[0129] The control unit 104 is specifically further configured to determine the temperature difference between the indoor environment temperature of the air conditioner and the set temperature of the air conditioner, denoted as the indoor temperature difference of the air conditioner; wherein the indoor temperature difference of the air conditioner, such as the indoor environment temperature T 环 and the set temperature T 设 . The specific functions and processes of the control unit 104 are also referred to step S410.

[0130] The control unit 104 is specifically further configured to determine whether the indoor temperature difference of the air conditioner is within a preset temperature range. The specific functions and processes of the control unit 104 are also referred to step S420.

[0131] The control unit 104 is further configured to, if it is determined that the indoor temperature difference of the air conditioner is within the preset temperature range, reduce the operating frequency of the compressor to a preset minimum frequency based on the current value, and then increase the operating wind level of the indoor fan, and make the air conditioner run according to the current adjusted operating logic for a preset third time and then restore the operating logic before adjustment. Here, increasing the operating wind level of the indoor fan can be specifically: if the set gear of the operating wind level of the indoor fan is greater than or equal to a preset maximum wind level, the operating wind level of the indoor fan is maintained at the set gear; if the set gear of the operating wind level of the indoor fan is less than the preset maximum wind level, the current value of the operating wind level of the indoor fan is increased by one gear. The preset third time is, for example, the preset time T3. The specific functions and processes of the control unit 104 are also described in step S430.

[0132] The control unit 104 is further configured to, if it is determined that the indoor temperature difference of the air conditioner is not within the preset temperature range, reduce the operating frequency of the compressor by a third set frequency based on the current value, and then increase the operating wind level of the indoor fan, and make the air conditioner run according to the current adjusted operating logic for a preset fourth time and then restore the operating logic before adjustment. Here, increasing the operating wind level of the indoor fan can be specifically: if the set gear of the operating wind level of the indoor fan is greater than or equal to a preset maximum wind level, the operating wind level of the indoor fan is maintained at the set gear; if the set gear of the operating wind level of the indoor fan is less than the preset maximum wind level, the current value of the operating wind level of the indoor fan is increased by one gear. The third set frequency is greater than the second set frequency, the third set frequency is, for example, the frequency ΔF3, and the preset fourth time is, for example, the preset time T4. The specific functions and processes of the control unit 104 are also described in step S440.

[0133] As shown in Figure 6 , the operating control method of the variable frequency air conditioner further includes: step 5, when the cumulative drainage amount P1 of the air conditioner in this time period exceeds the preset drainage amount P 预设2 , the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设 is recorded, the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设 is compared with a preset temperature range, step 51 or step 52 is executed according to the comparison result, and then step 6 is executed.

[0134] Step 51, if the difference ΔT between the indoor environment temperature T 环 and the set temperature T 设If the difference ΔT between the indoor environment temperature T and the set temperature T is within the preset temperature range, the running frequency of the compressor in the air conditioner is reduced to the lowest frequency, and the running wind level of the indoor fan is adjusted, see steps 511 and 512.

[0135] Step 511, if the original set wind level of the indoor unit is at a high wind level or an ultra-high wind level, the running wind level of the indoor fan is controlled to maintain this level, and the air conditioner is run for a preset time T3 in this state, and after the preset time T3 is met, the air conditioner is run according to the original running logic.

[0136] Step 512, if the original set wind level of the indoor unit is at any other level, the running wind level of the indoor fan is controlled to be increased by one level, so as to reduce the generation of condensate water in the air conditioner, and then step 6 is performed.

[0137] Step 52, if the indoor environment temperature T 环 is greater than the set temperature T 设 by a preset temperature range, the running frequency of the compressor in the air conditioner is reduced by ΔF3 based on the current running frequency of the compressor, and the running wind level of the indoor fan is adjusted, see steps 521 and 522.

[0138] Step 521, if the original set wind level of the indoor unit is at a high wind level or an ultra-high wind level, the running wind level of the indoor fan is controlled to maintain this level, and then step 6 is performed.

[0139] Step 522, if the original set wind level of the indoor unit is at any other level, the running wind level of the indoor fan is controlled to be increased by one level, so as to ensure the refrigeration effect and reduce the generation of condensate water, and the air conditioner is run for a preset time T4 in this state, and after the preset time T4 is met, the air conditioner is run according to the original running logic (i.e., step 6 is performed).

[0140] In the scheme of the application, by adding this control logic, the running parameters are adjusted differently while ensuring the comfort of the air conditioner. For example, when the user sets the temperature to 20℃, and the indoor environment temperature is reduced to 23℃ or below, the user's demand for refrigeration is relatively reduced at this time, but the condensate water on the indoor heat exchanger is serious at this time, and the running frequency of the compressor in the air conditioner needs to be reduced to the lowest frequency, and the amount of condensate water on the indoor heat exchanger is quickly reduced by increasing the air volume of the indoor fan.

[0141] Step 6, after the air conditioner is run according to the original running logic, return to step 2, and when the running time of the air conditioner again meets T 预设1 , record the drainage amount information, and adjust the running state of the air conditioner.

[0142] In the scheme of the present application, new air conditioner operation logic is added, suitable operation logic is selected, indoor heat exchanger condensate adhesion is reduced, and air conditioner operation efficiency is improved; wherein, the new operation logic detects the condensate amount during the operation of the air conditioner, detects the use environment, adjusts the operation state of the air conditioner, reduces the amount of water hanging, and improves the operation efficiency.

[0143] In the scheme of the present application, the drainage amount speed can also be used as a distinction, and the operation state of the air conditioner is adjusted according to the speed. Wherein, the drainage amount speed = drainage amount / drainage time, the indoor heat exchanger water hanging condition of the air conditioner is determined according to the drainage amount speed, and the determination method is similar to the determination method based on the cumulative drainage amount P1; at the same time, the indoor environment temperature T 环 is adjusted according to the difference ΔT between the set temperature T 设 , and the operation state of the air conditioner is adjusted, and the adjustment method is similar to the adjustment method based on the cumulative drainage amount P1.

[0144] In some embodiments, the control unit 104 increases the running wind gear of the indoor fan, including any of the following increase situations:

[0145] The first increase situation: the control unit 104 is specifically further configured to control the running wind gear of the indoor fan to maintain the set gear position if the set gear position of the running wind gear of the indoor fan is greater than or equal to the preset maximum wind gear, and specific examples can be referred to steps 411, 421, 511, and 521;

[0146] The second increase situation: the control unit 104 is specifically further configured to control the current value of the running wind gear of the indoor fan to increase one gear if the set gear position of the running wind gear of the indoor fan is less than the preset maximum wind gear, and specific examples can be referred to steps 412, 422, 512, and 522.

[0147] In the scheme of the present application, by determining the indoor heat exchanger condensate adhesion condition and comparing the difference between the real-time environment temperature and the user set temperature, the operation frequency and operation gear of the air conditioner are adjusted, which ensures the use effect of the air conditioner in refrigeration, reduces the indoor heat exchanger condensate adhesion condition, solves the problem that the air conditioner cannot effectively reduce the indoor heat exchanger condensate adhesion amount and reduce the dust adhesion amount on the indoor heat exchanger during refrigeration or dehumidification operation, thereby improving the refrigeration effect of the air conditioner and improving the use comfort of the air conditioner.
