[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Considering that when an air conditioner (such as a household split air conditioner) is running in a cooling or dehumidifying process, when there is too much condensed water on the indoor heat exchanger, it will affect the heat exchange efficiency of the air conditioner and the user experience. Some schemes provide an air conditioner and an indoor unit water pump control method for the air conditioner, wherein the air conditioner includes 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, and the controller is configured to: determine the humidity range of the indoor humidity based on the indoor humidity, and the humidity range includes a high humidity range, a medium humidity range or a low humidity range; when the air conditioner is running in a cooling mode, control the start state of the water pump based on the humidity range and the alarm signal of the indoor unit float switch, thereby realizing intelligent control of the water pump and avoiding energy waste. This invention adjusts the start state of the water pump through water level control to drain water. However, this scheme controls the start of the water pump through water level changes, does not determine and adjust whether the condensed water of the indoor heat exchanger is hanging water, and does not deal with the hanging water situation of the indoor heat exchanger.

[0033] Some other solutions provide an air conditioner and a water removal control method thereof. When a mobile air conditioner is running for a long time, a large amount of condensed water will be generated. By removing water from the water tank in advance, the condensed water accumulation speed is prevented from being too fast, which may cause the air conditioner to shut down. Thus, the continuous operation of the air conditioner is ensured while reducing the condensed water formation speed. This solution removes water from the water tank in advance based on the change of the water level in the water tank, but does not determine whether the heat exchanger has condensed water and how much water is hanging, and does not handle the water hanging situation of the heat exchanger.

[0034] In addition, the air conditioner (such as the user's home split inverter air conditioner), the indoor unit of the air conditioner collects the condensed water of the air conditioner through a water collection pan, and the indoor unit of the air conditioner is provided with a drainage hole. During the installation of the air conditioner, the user connects the drainage hole to the drainage pipe to drain the condensed water of the indoor unit to the outside.

[0035] Therefore, the scheme of the present invention proposes a control method for an air conditioner, specifically an operation control method for a variable frequency air conditioner. By detecting the condensed water attached to the indoor heat exchanger, the operating state of the air conditioner is adjusted to reduce the water hanging on the indoor heat exchanger of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve energy saving.

[0036] According to an embodiment of the present invention, a method for controlling an air conditioner is provided. Figure 1 The flow chart of an embodiment of the method of the present invention is shown in FIG. The air conditioner comprises an outdoor unit and an indoor unit, the outdoor unit comprises a compressor, and the indoor unit comprises an indoor heat exchanger and an indoor fan; a drainage amount detection device is provided in the drainage channel of the indoor unit, for detecting the drainage amount of condensed water in the drainage channel of the indoor unit as the drainage amount of condensed water generated on the indoor heat exchanger; in the scheme of the present invention, as Figure 1 As shown, the control method of the air conditioner includes: steps S110 to S150.

[0037] In step S110, when the air conditioner is turned on and operates in cooling mode or dehumidification mode, the set temperature of the air conditioner (such as the user set temperature T 设 ), obtain the set wind speed of the indoor fan (such as the user sets the running wind speed S 档 ); obtain the running time of the air conditioner (such as the running time of the air conditioner T 运行 ), obtain the indoor ambient temperature of the air conditioner (such as the indoor ambient temperature T 环 ); and, obtaining the drainage volume of the condensed water generated by the indoor heat exchanger, recorded as the drainage volume of the air conditioner (such as the drainage volume P of the indoor heat exchanger of the air conditioner). Specifically, obtaining the drainage volume of the condensed water generated by the indoor heat exchanger may be obtaining the drainage volume of the condensed water in the drainage channel of the indoor unit detected by the drainage volume detection device, as the drainage volume of the condensed water generated on the indoor heat exchanger.

[0038] At step S120, when it is determined that the running time of the air conditioner reaches the preset running time, the water hanging amount of the indoor heat exchanger is determined according to the running time of the air conditioner and the water discharge amount of the air conditioner; wherein the preset running time is such as the preset time T 预设1 .

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

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

[0041] At step S150, if it is determined that the water volume of the indoor heat exchanger is greater than or equal to a preset first water volume, the operating frequency of the compressor is adjusted according to the water volume of the indoor heat exchanger, the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, and the operating wind speed of the indoor fan is adjusted to adjust the water volume of the indoor heat exchanger, specifically to reduce the water volume of the indoor heat exchanger of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the energy saving performance; then return to continue to determine the water volume of the indoor heat exchanger according to the operating time of the air conditioner and the drainage volume of the air conditioner when it is determined again that the operating time of the air conditioner reaches the preset operating time, so as to realize dynamic cyclic adjustment of the water volume of the indoor heat exchanger.

[0042] The scheme of the present invention, based on the use of an air conditioner (such as a user's household split variable frequency air conditioner), adds a water discharge detection device and an operation control logic to detect the amount of condensed water on the indoor heat exchanger of the air conditioner, determine the amount of water attached to the indoor heat exchanger, and adjust the operating state of the air conditioner in combination with the difference between the indoor ambient temperature and the set temperature, thereby reducing the amount of water hanging on the indoor heat exchanger of the air conditioner, improving the heat exchange efficiency of the air conditioner, and improving energy saving.

[0043] In some implementations, in step S120, when it is determined that the running time of the air conditioner reaches the preset running time, the water hanging amount of the indoor heat exchanger is determined according to the running time of the air conditioner and the water discharge amount of the air conditioner, including any of the following determination situations:

[0044] The first determination scenario: accumulating the water discharge of the air conditioner obtained during the operation time of the air conditioner to obtain the accumulated water discharge of the air conditioner; using the accumulated water discharge of the air conditioner to represent the water discharge of the indoor heat exchanger. In the solution of the present invention, the operation state of the air conditioner can be adjusted according to the accumulated water discharge during the time period when the operation time of the air conditioner reaches the preset operation time.

[0045] The second determination scenario: the drainage volume of the air conditioner obtained during the operation time of the air conditioner is accumulated to obtain the accumulated drainage volume of the air conditioner; and the ratio of the accumulated drainage volume of the air conditioner to the operation time of the air conditioner is determined as the drainage rate of the air conditioner; and the drainage rate of the air conditioner is used to characterize the amount of water hanging on the indoor heat exchanger. In the scheme of the present invention, the drainage speed can also be used as a distinction to adjust the operating state of the air conditioner according to the speed. Among them, the drainage speed = drainage volume / drainage time. According to the drainage speed, the water hanging situation of the indoor heat exchanger of the air conditioner is determined, and the judgment method is similar to the judgment method based on the accumulated drainage volume P1.

[0046] In the scheme of the present invention, by detecting the amount of condensed water on the indoor heat exchanger of the air conditioner, it is possible to more accurately determine whether the indoor heat exchanger has too much water attached, thereby affecting the cooling or dehumidification effect; by detecting the amount of condensed water on the indoor heat exchanger of the air conditioner, it is possible to determine the condition of condensed water attached to the indoor heat exchanger, thereby solving the problem that the split unit of the air conditioner in the past could not effectively determine the condition of condensed water on the indoor heat exchanger.

[0047] In some embodiments, in step S150, when the water volume of the indoor heat exchanger is greater than or equal to a preset first water volume, the operating frequency of the compressor is adjusted according to the water volume of the indoor heat exchanger, the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, and the operating wind speed of the indoor fan is adjusted to adjust the specific process of adjusting the water volume of the indoor heat exchanger. Please refer to the following exemplary description.

[0048] Combine the following Figure 2 The flowchart of an embodiment of adjusting the water hanging amount of the indoor heat exchanger in the method of the present invention further illustrates the specific process of adjusting the water hanging amount of the indoor heat exchanger in step S120, including: steps S210 to S230.

[0049] Step S210, when the water volume of the indoor heat exchanger is greater than or equal to a preset first water volume, determining whether the water volume of the indoor heat exchanger is less than a preset second water volume; wherein, when the water volume of the indoor heat exchanger is measured by the accumulated water volume meter of the air conditioner, the preset first water volume is such as the preset water volume P 预设1 The preset second water volume is such as the preset discharge volume P 预设2 .

[0050] Step S220, when the water hanging amount of the indoor heat exchanger is greater than or equal to a preset first water amount, if it is determined that the water hanging amount of the indoor heat exchanger is less than a preset second water amount, then according to the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, the operating frequency of the compressor is adjusted, and the operating wind speed of the indoor fan is adjusted to make a first adjustment to the water hanging amount of the indoor heat exchanger.

[0051] Step S230, when 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, then according to the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, the operating frequency of the compressor is adjusted, and the operating wind speed of the indoor fan is adjusted to make a second adjustment to the water hanging amount of the indoor heat exchanger.

[0052] Figure 6 FIG. 1 is a flow chart of an embodiment of the method for controlling the operation of a variable frequency air conditioner of the present invention.档 Indicates the remote control setting power-on position; T 设 Indicates the remote control startup setting temperature; T 运行 Indicates the operating time of the air conditioner; T 预设1 Indicates preset time; P 预设1 , P 预设2 , P 预设3 ——All represent the information of preset water discharge; T1, T2, T3, T4 and other parameters all represent preset time; P represents the information of air conditioner water discharge; ΔT represents the temperature difference; T 环 Indicates the indoor ambient temperature. For example: T 预设1 For 1h, P 预设1 500ml, P 预设2 1000ml, P 预设3 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 and the water discharge volume is large, the operation time according to this logic needs to be longer to ensure that the generation of condensed water in the air conditioner can be fully reduced. Therefore, the preset time T3 is longer than the preset time T1; when the water discharge volume is in the same interval and the temperature difference ΔT is not within the preset range, while ensuring the cooling effect, the operation time according to this logic is appropriately lengthened to ensure that the generation of condensed water in the air conditioner can be fully reduced. Therefore, the preset time T2 is longer than the preset time T1, and the preset time T4 is longer than the preset time T3. Figure 6 As shown, the operation control method of the variable frequency air conditioner includes:

[0053] Step 1: When the user uses the air conditioner for cooling or dehumidification, record the user's set operating wind speed S 档 , user set temperature T 设 , record the indoor ambient temperature T 环 , record the air conditioner running time T 运行 , detect and record the water discharge volume P of the indoor heat exchanger of the air conditioner, and then execute step 2 after recording.

[0054] Step 2: When the air conditioner running time reaches the preset time T 预设1 When the accumulated water discharge volume P1 of the air conditioner in this time period (i.e., the time period of the air conditioner operation) is recorded, it is determined whether the accumulated water discharge volume P1 of the air conditioner in this time period is lower than the preset water discharge volume P 预设1 : If yes, the air conditioner maintains the original state and returns to step 2. When the air conditioner running time reaches the preset time T again 预设1 Otherwise, go to step 3.

[0055] In step 2, when the accumulated water discharge volume P1 of the air conditioner during this period is less than the preset water discharge volume P 预设1During the cooling process of the air conditioner, the indoor heat exchanger will always produce condensed water. The amount of condensed water will vary in different states of the air conditioner. When the condensed water is less, the indoor heat exchanger will also have less water hanging, and no additional treatment is required.

[0056] Step 3: Determine whether the accumulated water discharge volume P1 of the air conditioner during this period is within the preset water discharge volume P 预设1 With the preset displacement P 预设2 The interval range between: If yes, execute step 4 to make a first adjustment to the water hanging amount of the indoor heat exchanger; otherwise, execute step 5 to make a second adjustment to the water hanging amount of the indoor heat exchanger.

[0057] In the scheme of the present invention, on the basis of the basic functions of the air conditioner, a new drainage detection device is added at the connection between the drainage hole and the drainage pipe of the indoor unit; the drainage volume of the condenser water during the cooling or dehumidification process of the air conditioner is detected by the drainage detection device, and the water hanging situation of the indoor heat exchanger is determined. At the same time, by detecting the change of the indoor ambient temperature, the operating state of the air conditioner is adjusted according to the difference between the indoor ambient temperature and the set temperature, the water hanging amount of the indoor heat exchanger is reduced, and the operating efficiency of the air conditioner is improved.

[0058] In some embodiments, in step S220, 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, 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 wind speed of the indoor fan is adjusted to perform the first adjustment on the water volume of the indoor heat exchanger. For the specific process, see the following exemplary description.

[0059] Combine the following Figure 3 The flowchart of an embodiment of the method of the present invention for first adjusting the water hanging amount of the indoor heat exchanger further illustrates the specific process of first adjusting the water hanging amount of the indoor heat exchanger in step S220, including: step S310 to step S340.

[0060] Step S310, determining the temperature difference between the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, which is recorded 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, determining whether the indoor temperature difference of the air conditioner is within a 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 operating frequency of the compressor is reduced by a first set frequency based on the current value, and after the operating wind speed of the indoor fan is increased, the air conditioner is operated according to the currently adjusted operating logic for a preset first time and then restores the operating logic before adjustment. Here, increasing the operating wind speed of the indoor fan can be specifically: if the set gear of the operating wind speed of the indoor fan is greater than or equal to the preset maximum wind speed, the operating wind speed of the indoor fan is controlled to maintain the set gear; if the set gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed, the current value of the operating wind speed of the indoor fan is controlled to be increased by one gear. Among them, the first set frequency is such as frequency ΔF1, and the preset first time is such as preset time 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 operating frequency of the compressor is reduced by a second set frequency based on the current value, and after the operating wind speed of the indoor fan is increased, the air conditioner is operated according to the currently adjusted operating logic for a preset second time and then restores the operating logic before adjustment. Here, increasing the operating wind speed of the indoor fan can be specifically: if the setting gear of the operating wind speed of the indoor fan is greater than or equal to the preset maximum wind speed, the operating wind speed of the indoor fan is controlled to maintain the setting gear; if the setting gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed, the current value of the operating wind speed of the indoor fan is controlled to be increased by one gear. Among them, the first set frequency is greater than the second set frequency, the second set frequency is such as frequency ΔF2, and the preset second time is such as preset time T2. Among them, the set maximum wind speed is such as high wind speed or super strong wind speed.

[0064] like Figure 6 As shown, the operation control method of the variable frequency air conditioner also includes: step 4, when the accumulated water discharge volume P1 of the air conditioner during the time period is at the preset water discharge volume P 预设1 With the preset displacement P 预设2 When the indoor temperature is between 环 With the set temperature T 设 The difference ΔT is the indoor ambient temperature T 环 With the set temperature T 设 The difference ΔT 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.

[0065] Step 41: If the indoor ambient temperature T 环 With the set temperature T 设If the difference ΔT is within the preset temperature range, then based on the current operating frequency of the compressor in the air conditioner, the operating frequency of the compressor ΔF1 is appropriately reduced; at the same time, the operating wind speed of the indoor fan is adjusted, see steps 411 and 412 for details. For example: ΔT can be preset to 3°C, at which time the room temperature is close to the user's set temperature, and the user's cooling demand for the air conditioner is reduced. ΔF1 can be 14Hz, and the reduced operating frequency cannot be lower than the minimum frequency allowed for the air conditioner to operate.

[0066] Step 411: If the original setting wind speed of the indoor unit is at the high wind speed or the super strong wind speed, the running wind speed of the indoor fan is controlled to maintain this gear. This state runs for time T1 (such as 15 minutes), and then executes step 6.

[0067] Step 412, if the original setting wind speed of the indoor unit is in other gears, then control the running wind speed of the indoor fan to increase one gear to reduce the generation of condensed water in the air conditioner, and run in this state for the preset time T1. After the preset time T1 is met, it runs according to the original operation logic (i.e., execute step 6).

[0068] Step 42: If the difference ΔT between the indoor ambient temperature Tring and the set temperature Tset exceeds the preset temperature range, the operating frequency of the compressor ΔF2 is appropriately reduced based on the current operating frequency of the compressor in the air conditioner, and the operating wind speed of the indoor fan is adjusted. For details, see steps 421 and 422. For example, ΔF2 can be 8 Hz, and the reduced operating frequency cannot be lower than the lowest frequency allowed by the air conditioner.

[0069] Step 421: If the original setting wind speed of the indoor unit is at the high wind speed or the super wind speed, the running wind speed of the indoor fan is controlled to maintain this gear. This state runs for time T2 (such as 30 minutes), and then executes step 6.

[0070] Step 422, if the original setting wind speed of the indoor unit is in other gears, then control the running wind speed of the indoor fan to increase one gear to run, while ensuring the cooling effect, while reducing the generation of condensed water, and run in this state for the preset time T2. After the preset time T2 is met, it runs according to the original operation logic (that is, execute step 6).

[0071] In the solution of the present invention, 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, when the user sets the temperature to 20°C, when the indoor ambient temperature drops to 23°C or below, the user's demand for cooling is relatively reduced. At this time, the operating frequency of the compressor is reduced by ΔF1, the gear position of the indoor fan running wind gear is increased, and the air volume is increased. The evaporation temperature of the indoor heat exchanger can be increased, and the generation of condensed water can be reduced. At the same time, by increasing the air volume, the amount of attached water in the indoor heat exchanger can be taken away. For example, when the user sets the temperature to 20°C, when the indoor ambient temperature drops to 25°C, the user still has a demand for cooling. At this time, the operating frequency of the compressor is appropriately reduced by ΔF2, the gear position of the indoor fan running wind gear is increased, the air volume is increased, and the generation of condensed water in the indoor heat exchanger is reduced, while ensuring the cooling effect. Usually, the reduction amplitude ΔF1 is higher 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 wind speed of the indoor fan is adjusted to perform a second adjustment on the water volume of the indoor heat exchanger. For the specific process, see the following exemplary description.

[0073] Combine the following Figure 4 The flowchart of an embodiment of the method of the present invention for performing a second adjustment on the water hanging amount of the indoor heat exchanger further illustrates the specific process of performing a second adjustment on the water hanging amount of the indoor heat exchanger in step S230, including: steps S410 to S440.

[0074] Step S410, determining the temperature difference between the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, which is recorded 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, determining whether the indoor temperature difference of the air conditioner is within a 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, and after the operating speed of the indoor fan is increased, the air conditioner is operated according to the currently adjusted operating logic for the preset third time and then restores the operating logic before adjustment. Here, increasing the operating speed of the indoor fan can be specifically: if the set gear of the operating speed of the indoor fan is greater than or equal to the preset maximum speed, the operating speed of the indoor fan is controlled to maintain the set gear; if the set gear of the operating speed of the indoor fan is less than the preset maximum speed, the current value of the operating speed of the indoor fan is controlled to be increased by one gear. Among them, the preset third time is such as 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, and after the operating wind speed of the indoor fan is increased, the air conditioner is operated according to the currently adjusted operating logic for a preset fourth time and then restores the operating logic before adjustment. Here, increasing the operating wind speed of the indoor fan can be specifically: if the set gear of the operating wind speed of the indoor fan is greater than or equal to the preset maximum wind speed, the operating wind speed of the indoor fan is controlled to maintain the set gear; if the set gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed, the current value of the operating wind speed of the indoor fan is controlled to be increased by one gear. Among them, the third set frequency is greater than the second set frequency, the third set frequency is such as frequency ΔF3, and the preset fourth time is such as preset time T4. Among them, since the evaporator is more likely to be waterlogged in this range, the third set frequency should be greater than the second set frequency, such as ΔF2 is 8Hz and ΔF3 is 12Hz, which can more effectively reduce the evaporator waterlogging situation, and the reduced operating frequency cannot be lower than the minimum allowable operating frequency of the air conditioner.

[0078] like Figure 6 As shown, the operation control method of the variable frequency air conditioner also includes: step 5, when the accumulated water discharge volume P1 of the air conditioner during the time period exceeds the preset water discharge volume P 预设2 When the indoor environment temperature is T 环 With the set temperature T 设 The difference ΔT is the indoor ambient temperature T 环 With the set temperature T 设 The difference ΔT is compared with the preset temperature range, and step 51 or step 52 is executed according to the comparison result, and then step 6 is executed.

[0079] Step 51: If the indoor ambient temperature T 环 With the set temperature T 设If the difference ΔT is within the preset temperature range, the operating frequency of the compressor in the air conditioner is reduced to the lowest frequency, and the operating wind speed of the indoor fan is adjusted at the same time. For details, see step 511 and step 512.

[0080] Step 511, if the original setting wind speed of the indoor unit is at the high wind speed or the super strong speed, the operating wind speed of the indoor fan is controlled to maintain this speed, and it runs in this state for a preset time T3. After the preset time T3 is met, it runs according to the original operation logic.

[0081] Step 512: If the original setting wind speed of the indoor unit is in other gears, the running wind speed of the indoor fan is controlled to increase one gear. This state runs for time T3 (such as 25 minutes) to reduce the generation of condensed water of the air conditioner, and then execute step 6.

[0082] Step 52: If the indoor ambient temperature T 环 With the set temperature T 设 If the difference ΔT exceeds the preset temperature range, the operating frequency of the compressor is appropriately reduced by ΔF3 based on the current operating frequency of the compressor in the air conditioner, and the operating wind speed of the indoor fan is adjusted at the same time. For details, see steps 521 and 522.

[0083] Step 521: If the original setting wind speed of the indoor unit is at the high wind speed or the super wind speed, the running wind speed of the indoor fan is controlled to maintain this gear. This state runs for time T4 (such as 40 minutes), and then executes step 6.

[0084] Step 522, if the original setting wind speed of the indoor unit is in other gears, then control the running wind speed of the indoor fan to increase one gear to ensure the cooling effect while reducing the generation of condensed water. Run in this state for the preset time T4. After the preset time T4 is met, run according to the original operation logic (i.e., execute step 6).

[0085] In the solution of the present invention, by adding this control logic, different adjustments are made to the operating parameters while ensuring the comfort of the air conditioner. For example, when the user sets the temperature to 20°C, when the indoor ambient temperature drops to 23°C or below, the user's demand for cooling is relatively reduced, but the indoor heat exchanger is seriously waterlogged at this time, and the operating frequency of the compressor in the air conditioner needs to be reduced to the lowest frequency. At the same time, by increasing the air volume of the indoor fan, the amount of water attached to the indoor heat exchanger can be quickly reduced.

[0086] Step 6: When the air conditioner runs according to the original operation logic, return to step 2. When the air conditioner running time meets T again, 预设1 When the water discharge information is recorded, the operating status of the air conditioner is adjusted.

[0087] In the scheme of the present invention, a new air conditioner operating logic is added, and a suitable operating logic is selected to reduce the adhesion of condensed water to the indoor heat exchanger and improve the operating efficiency of the air conditioner; wherein, the new operating logic detects the amount of condensed water during the operation of the air conditioner and detects the use environment to adjust the operating state of the air conditioner, reduce the amount of water hanging, and improve the operating efficiency.

[0088] In the solution of the present invention, the drainage speed can also be used as a distinction, and the air conditioner operation state can be adjusted according to the speed. Among them, the drainage speed = drainage volume / drainage time. According to the drainage speed, the water hanging condition of the indoor heat exchanger of the air conditioner is determined. The judgment method is similar to the judgment method based on the cumulative drainage volume P1. At the same time, according to the indoor ambient temperature T 环 With the set temperature T 设 The difference ΔT is used to adjust the operating state of the air conditioner in a manner similar to that based on the accumulated drainage volume P1.

[0089] In some implementations, raising the operating wind speed of the indoor fan in any of step S330, step S340, step S430, and step S440 includes any of the following raising situations:

[0090] The first increase situation: if the set gear of the operating wind speed of the indoor fan is greater than or equal to the preset maximum wind speed, the operating wind speed of the indoor fan is controlled to maintain the set gear. For details, please refer to the examples shown in steps 411, 421, 511, and 521.

[0091] The second increase situation: if the set gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed, the current value of the operating wind speed of the indoor fan is controlled to be increased by one gear. For details, please refer to the examples shown in steps 412, 422, 512, and 522.

[0092] In the scheme of the present invention, by judging the condensation water adhesion condition of the indoor heat exchanger and comparing the difference between the real-time temperature of the environment and the temperature set by the user, the operating frequency and the operating gear of the air conditioner are adjusted, so as to reduce the condensation water adhesion condition of the indoor heat exchanger while ensuring the cooling effect of the air conditioner. This solves the problem that the air conditioner cannot effectively reduce the amount of condensation water adhesion on the indoor heat exchanger and the amount of dust adhesion on the indoor heat exchanger during the cooling or dehumidification operation, thereby improving the cooling effect of the air conditioner and improving the comfort of use of the air conditioner.

[0093] The technical solution of this embodiment is adopted, by arranging a drainage amount detection device at the connection between the drainage hole and the drainage pipe of the indoor unit, using the drainage amount detection device to detect the drainage amount of condensed water of the indoor unit, determining the cumulative drainage amount of the indoor unit or the drainage rate of the indoor unit according to the detected drainage amount of the condensed water of the indoor unit, and determining the hanging water amount of the indoor heat exchanger according to the cumulative drainage amount of the indoor unit or the drainage rate of the indoor unit; adjusting the operating state of the compressor and the indoor fan in combination with the difference between the indoor ambient temperature and the set temperature to adjust the operating logic of the air conditioner, and controlling the hanging water amount of the indoor heat exchanger; thereby, by detecting the hanging water situation of the indoor heat exchanger and adjusting the operating state of the air conditioner in combination with the difference between the indoor ambient temperature and the set temperature, the hanging water amount of the indoor heat exchanger is reduced, and the operating efficiency of the air conditioner is improved.

[0094] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for the air conditioner is also provided. Figure 5 The schematic diagram of the structure of an embodiment of the device of the present invention is shown. The air conditioner comprises an outdoor unit and an indoor unit, the outdoor unit comprises a compressor, and the indoor unit comprises an indoor heat exchanger and an indoor fan; a drainage amount detection device is provided in the drainage channel of the indoor unit, for detecting the drainage amount of condensed water in the drainage channel of the indoor unit as the drainage amount of condensed water generated on the indoor heat exchanger; in the scheme of the present invention, as Figure 5 As shown, the control device of the air conditioner includes: an acquisition unit 102 and a control unit 104.

[0095] The acquisition unit 102 is configured to acquire the set temperature of the air conditioner (such as the user set temperature T 设 ), obtain the set wind speed of the indoor fan (such as the user sets the running wind speed S 档 ); obtain the running time of the air conditioner (such as the running time of the air conditioner T 运行 ), obtain the indoor ambient temperature of the air conditioner (such as the indoor ambient temperature T 环 ); and, obtaining the drainage volume of the condensed water generated by the indoor heat exchanger, recorded as the drainage volume of the air conditioner (such as the drainage volume P of the indoor heat exchanger of the air conditioner); specifically, obtaining the drainage volume of the condensed water generated by the indoor heat exchanger can be to obtain the drainage volume of the condensed water in the drainage channel of the indoor unit detected by the drainage volume detection device, as the drainage volume of the condensed water generated on the indoor heat exchanger. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0096] The control unit 104 is configured to determine the amount of water to be hung on the indoor heat exchanger according to the running time of the air conditioner and the drainage volume of the air conditioner when it is determined that the running time of the air conditioner reaches the preset running time; wherein the preset running time is such as the preset time T 预设1 The specific functions and processing of the control unit 104 refer to step S120.

[0097] The control unit 104 is further configured to determine whether the water volume of the indoor heat exchanger is less than a preset first water volume. The specific functions and processing of the control unit 104 are also shown in step S130.

[0098] The control unit 104 is further configured to control the air conditioner to maintain the current state of operation if it is determined that the water volume of the indoor heat exchanger is less than a preset first water volume, and then return to continue to determine the water volume of the indoor heat exchanger according to the running time of the air conditioner and the water volume of the air conditioner when it is determined again that the running time of the air conditioner reaches the preset running time. The specific functions and processing of the control unit 104 are also shown in step S140.

[0099] The control unit 104 is also configured to adjust the operating frequency of the compressor and the operating wind speed of the indoor fan according to the water volume of the indoor heat exchanger, the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, if it is determined that the water volume of the indoor heat exchanger is greater than or equal to the preset first water volume, so as to adjust the water volume of the indoor heat exchanger, specifically to reduce the water volume of the indoor heat exchanger of the air conditioner, improve the heat exchange efficiency of the air conditioner, and improve the energy saving performance; and then return to determine the water volume of the indoor heat exchanger according to the running time of the air conditioner and the drainage volume of the air conditioner when it is determined again that the running time of the air conditioner reaches the preset running time, so as to realize the dynamic cycle adjustment of the water volume of the indoor heat exchanger. The specific functions and processing of the control unit 104 are also shown in step S150.

[0100] The scheme of the present invention, based on the use of an air conditioner (such as a user's household split variable frequency air conditioner), adds a water discharge detection device and an operation control logic to detect the amount of condensed water on the indoor heat exchanger of the air conditioner, determine the amount of water attached to the indoor heat exchanger, and adjust the operating state of the air conditioner in combination with the difference between the indoor ambient temperature and the set temperature, thereby reducing the amount of water hanging on the indoor heat exchanger of the air conditioner, improving the heat exchange efficiency of the air conditioner, and improving energy saving.

[0101] In some implementations, the control unit 104, when determining that the running time of the air conditioner reaches the 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 situations:

[0102] The first determination scenario: the control unit 104 is further configured to accumulate the water discharge of the air conditioner obtained during the operation time of the air conditioner to obtain the accumulated water discharge of the air conditioner; and use the accumulated water discharge of the air conditioner to represent the water discharge amount of the indoor heat exchanger. In the solution of the present invention, the operation state of the air conditioner can be adjusted according to the accumulated water discharge during the time period when the operation time of the air conditioner reaches the preset operation time.

[0103] The second determination scenario: the control unit 104 is also specifically configured to accumulate the drainage volume of the air conditioner obtained during the operation time of the air conditioner to obtain the cumulative drainage volume of the air conditioner; and determine the ratio of the cumulative drainage volume of the air conditioner to the operation time of the air conditioner as the drainage rate of the air conditioner; and use the drainage rate of the air conditioner to characterize the amount of water hanging on the indoor heat exchanger. In the scheme of the present invention, the drainage speed can also be used as a distinction to adjust the operating state of the air conditioner according to the speed. Among them, the drainage speed = drainage volume / drainage time. According to the drainage speed, the water hanging situation of the indoor heat exchanger of the air conditioner is determined, and the judgment method is similar to the judgment method based on the cumulative drainage volume P1.

[0104] In the scheme of the present invention, by detecting the amount of condensed water on the indoor heat exchanger of the air conditioner, it is possible to more accurately determine whether the indoor heat exchanger has too much water attached, thereby affecting the cooling or dehumidification effect; by detecting the amount of condensed water on the indoor heat exchanger of the air conditioner, it is possible to determine the condition of condensed water attached to the indoor heat exchanger, thereby solving the problem that the split unit of the air conditioner in the past could not effectively determine the condition of condensed water on the indoor heat exchanger.

[0105] In some embodiments, the control unit 104, when the water hanging amount of the indoor heat exchanger is greater than or equal to a preset first water amount, adjusts the operating frequency of the compressor and the operating wind speed of the indoor fan according to the water hanging amount of the indoor heat exchanger, the indoor ambient 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 further configured to determine whether the amount of water hanging from the indoor heat exchanger is less than a preset second amount of water when the amount of water hanging from the indoor heat exchanger is greater than or equal to a preset first amount of water; wherein, when the amount of water hanging from the indoor heat exchanger is measured by the accumulated water discharge meter of the air conditioner, the preset first amount of water is such as the preset discharge amount P预设1 The preset second water volume is such as the preset discharge volume P 预设2 The specific functions and processing of the control unit 104 can also be found in step S210.

[0107] The control unit 104 is further configured to adjust the operating frequency of the compressor and the operating wind speed of the indoor fan according to the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, so as to make a first adjustment to the water volume of the indoor heat exchanger, if it is determined that the water volume of the indoor heat exchanger is less than the preset second water volume when the water volume of the indoor heat exchanger is greater than or equal to the preset first water volume. The specific functions and processing of the control unit 104 are also shown in step S220.

[0108] The control unit 104 is further configured to adjust the operating frequency of the compressor and the operating wind speed of the indoor fan according to the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, so as to make a second adjustment to the water volume of the indoor heat exchanger, if it is determined that the water volume of the indoor heat exchanger is greater than or equal to the preset second water volume when the water volume of the indoor heat exchanger is greater than or equal to the preset first water volume. The specific functions and processing of the control unit 104 are also referred to step S230.

Figure 6 As shown, the operation control method of the variable frequency air conditioner includes:

[0110] Step 1: When the user uses the air conditioner for cooling or dehumidification, record the user's set operating wind speed S 档 , user set temperature T 设 , record the indoor ambient temperature T 环 , record the air conditioner running time T 运行 , detect and record the water discharge volume P of the indoor heat exchanger of the air conditioner, and then execute step 2 after recording.

[0111] Step 2: When the air conditioner running time reaches the preset time T 预设1 When the accumulated water discharge volume P1 of the air conditioner in this time period (i.e., the time period of the air conditioner operation) is recorded, it is determined whether the accumulated water discharge volume P1 of the air conditioner in this time period is lower than the preset water discharge volume P 预设1 : If yes, the air conditioner maintains the original state and returns to step 2. When the air conditioner running time reaches the preset time T again 预设1 Otherwise, go to step 3.

[0112] In step 2, when the accumulated water discharge volume P1 of the air conditioner during this period is less than the preset water discharge volume P 预设1 During the cooling process of the air conditioner, the indoor heat exchanger will always produce condensed water. The amount of condensed water will vary in different states of the air conditioner. When the condensed water is less, the indoor heat exchanger will also have less water hanging, and no additional treatment is required.

[0113] Step 3: Determine whether the accumulated water discharge volume P1 of the air conditioner during this period is within the preset water discharge volume P 预设1 With the preset displacement P 预设2 The interval range between: If yes, execute step 4 to make a first adjustment to the water hanging amount of the indoor heat exchanger; otherwise, execute step 5 to make a second adjustment to the water hanging amount of the indoor heat exchanger.

[0114] In the scheme of the present invention, on the basis of the basic functions of the air conditioner, a new drainage detection device is added at the connection between the drainage hole and the drainage pipe of the indoor unit; the drainage volume of the condenser water during the cooling or dehumidification process of the air conditioner is detected by the drainage detection device, and the water hanging situation of the indoor heat exchanger is determined. At the same time, by detecting the change of the indoor ambient temperature, the operating state of the air conditioner is adjusted according to the difference between the indoor ambient temperature and the set temperature, the water hanging amount of the indoor heat exchanger is reduced, and the operating efficiency of the air conditioner is improved.

[0115] In some embodiments, the control unit 104, 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, adjusts the operating frequency of the compressor and the operating wind speed of the indoor fan 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, including:

[0116] The control unit 104 is further configured to determine the temperature difference between the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, which is recorded as the indoor temperature difference of the air conditioner. 环 With the set temperature T 设The specific functions and processing of the control unit 104 are also shown in 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 also shown in step S320.

[0118] The control unit 104 is also specifically 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 set frequency based on the current value, and after increasing the operating wind speed of the indoor fan, make the air conditioner run according to the currently adjusted operating logic for a preset first time and then restore the operating logic before adjustment; here, increasing the operating wind speed of the indoor fan can be specifically: if the setting gear of the operating wind speed of the indoor fan is greater than or equal to the preset maximum wind speed, control the operating wind speed of the indoor fan to maintain the setting gear; if the setting gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed, control the current value of the operating wind speed of the indoor fan to increase by one gear. Among them, the first set frequency is such as frequency ΔF1, and the preset first time is such as preset time T1. The specific functions and processing of the control unit 104 can also be seen in step S330.

[0119] The control unit 104 is also specifically 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 to a second set frequency based on the current value, and after increasing the operating wind speed of the indoor fan, make the air conditioner run according to the currently adjusted operating logic for a preset second time and then restore the operating logic before adjustment; here, increasing the operating wind speed of the indoor fan can be specifically: if the setting gear of the operating wind speed of the indoor fan is greater than or equal to the preset maximum wind speed, control the operating wind speed of the indoor fan to maintain the setting gear; if the setting gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed, control the current value of the operating wind speed of the indoor fan to increase by one gear. Among them, the first set frequency is greater than the second set frequency, the second set frequency is such as frequency ΔF2, and the preset second time is such as preset time T2. The specific functions and processing of the control unit 104 can also be seen in step S340.

[0120] like Figure 6 As shown, the operation control method of the variable frequency air conditioner also includes: step 4, when the accumulated water discharge volume P1 of the air conditioner during the time period is at the preset water discharge volume P 预设1 With the preset displacement P 预设2 When the indoor temperature is between 环 With the set temperature T 设 The difference ΔT is the indoor ambient temperature T环 With the set temperature T 设 The difference ΔT 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 indoor ambient temperature T 环 With the set temperature T 设 If the difference ΔT is within the preset temperature range, the operating frequency of the compressor is appropriately reduced by ΔF1 based on the current operating frequency of the compressor in the air conditioner; at the same time, the operating wind speed of the indoor fan is adjusted, see steps 411 and 412 for details.

[0122] Step 411: If the original setting wind speed of the indoor unit is at the high wind speed or the super strong wind speed, the running wind speed of the indoor fan is controlled to maintain this gear, and then step 6 is executed.

[0123] Step 412, if the original setting wind speed of the indoor unit is in other gears, then control the running wind speed of the indoor fan to increase one gear to reduce the generation of condensed water in the air conditioner, and run in this state for the preset time T1. After the preset time T1 is met, it runs according to the original operation logic (i.e., execute step 6).

[0124] Step 42: If the indoor ambient temperature T 环 With the set temperature T 设 If the difference ΔT exceeds the preset temperature range, the operating frequency of the compressor is appropriately reduced by ΔF2 based on the current operating frequency of the compressor in the air conditioner, and the operating wind speed of the indoor fan is adjusted at the same time, see steps 421 and 422 for details.

[0125] Step 421: If the original setting wind speed of the indoor unit is at the high wind speed or the super strong wind speed, the running wind speed of the indoor fan is controlled to maintain this speed, and then step 6 is executed.

[0126] Step 422, if the original setting wind speed of the indoor unit is in other gears, then control the running wind speed of the indoor fan to increase one gear to run, while ensuring the cooling effect, while reducing the generation of condensed water, and run in this state for the preset time T2. After the preset time T2 is met, it runs according to the original operation logic (that is, execute step 6).

[0127] In the solution of the present invention, 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, when the user sets the temperature to 20°C, when the indoor ambient temperature drops to 23°C or below, the user's demand for cooling is relatively reduced. At this time, the operating frequency of the compressor is reduced by ΔF1, the gear position of the indoor fan running wind gear is increased, and the air volume is increased. The evaporation temperature of the indoor heat exchanger can be increased, and the generation of condensed water can be reduced. At the same time, by increasing the air volume, the amount of attached water in the indoor heat exchanger can be taken away. For example, when the user sets the temperature to 20°C, when the indoor ambient temperature drops to 25°C, the user still has a demand for cooling. At this time, the operating frequency of the compressor is appropriately reduced by ΔF2, the gear position of the indoor fan running wind gear is increased, the air volume is increased, and the generation of condensed water in the indoor heat exchanger is reduced, while ensuring the cooling effect. Usually, the reduction amplitude ΔF1 is higher than ΔF2.

[0128] In some embodiments, the control unit 104, when the water volume of the indoor heat exchanger is greater than or equal to a preset second water volume, adjusts the operating frequency of the compressor and the operating wind speed of the indoor fan according to the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner to perform a second adjustment on the water volume of the indoor heat exchanger, including:

[0129] The control unit 104 is further configured to determine a temperature difference between the indoor ambient temperature of the air conditioner and the set temperature of the air conditioner, which is recorded 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 specific functions and processing of the control unit 104 also refer to step S410.

[0130] 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 also shown in step S420.

[0131] The control unit 104 is also specifically 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 to a preset minimum frequency based on the current value, and after increasing the operating wind speed of the indoor fan, make the air conditioner run according to the currently adjusted operating logic for a preset third time and then restore the operating logic before adjustment; here, increasing the operating wind speed of the indoor fan can be specifically: if the set gear of the operating wind speed of the indoor fan is greater than or equal to the preset maximum wind speed, control the operating wind speed of the indoor fan to maintain the set gear; if the set gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed, control the current value of the operating wind speed of the indoor fan to increase by one gear. Among them, the preset third time is such as the preset time T3. The specific functions and processing of the control unit 104 can also be seen in step S430.

[0132] The control unit 104 is also specifically 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 after raising the operating wind speed of the indoor fan, make the air conditioner run according to the currently adjusted operating logic for a preset fourth time and then restore the operating logic before adjustment. Here, raising the operating wind speed of the indoor fan can be specifically: if the setting gear of the operating wind speed of the indoor fan is greater than or equal to the preset maximum wind speed, control the operating wind speed of the indoor fan to maintain the setting gear; if the setting gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed, control the current value of the operating wind speed of the indoor fan to be raised by one gear. Among them, the third set frequency is greater than the second set frequency, the third set frequency is such as frequency ΔF3, and the preset fourth time is such as preset time T4. The specific functions and processing of the control unit 104 can also be seen in step S440.

[0133] like Figure 6 As shown, the operation control method of the variable frequency air conditioner also includes: step 5, when the accumulated water discharge volume P1 of the air conditioner during the time period exceeds the preset water discharge volume P 预设2 When the indoor environment temperature is T 环 With the set temperature T 设 The difference ΔT is the indoor ambient temperature T 环 With the set temperature T 设 The difference ΔT is compared with the preset temperature range, and step 51 or step 52 is executed according to the comparison result, and then step 6 is executed.

[0134] Step 51: If the indoor ambient temperature T 环 With the set temperature T 设If the difference ΔT is within the preset temperature range, the operating frequency of the compressor in the air conditioner is reduced to the lowest frequency, and the operating wind speed of the indoor fan is adjusted at the same time. For details, see step 511 and step 512.

[0135] Step 511, if the original setting wind speed of the indoor unit is at the high wind speed or the super strong speed, the operating wind speed of the indoor fan is controlled to maintain this speed, and it runs in this state for a preset time T3. After the preset time T3 is met, it runs according to the original operation logic.

[0136] Step 512: If the original setting wind speed of the indoor unit is in other gears, the running wind speed of the indoor fan is controlled to increase one gear to reduce the generation of condensed water of the air conditioner, and then execute step 6.

[0137] Step 52: If the indoor ambient temperature T 环 With the set temperature T 设 If the difference ΔT exceeds the preset temperature range, the operating frequency of the compressor is appropriately reduced by ΔF3 based on the current operating frequency of the compressor in the air conditioner, and the operating wind speed of the indoor fan is adjusted at the same time. For details, see steps 521 and 522.

[0138] Step 521: If the original setting wind speed of the indoor unit is at the high wind speed or the super strong wind speed, the running wind speed of the indoor fan is controlled to maintain this speed, and then step 6 is executed.

[0139] Step 522, if the original setting wind speed of the indoor unit is in other gears, then control the running wind speed of the indoor fan to increase one gear to ensure the cooling effect while reducing the generation of condensed water. Run in this state for the preset time T4. After the preset time T4 is met, run according to the original operation logic (i.e., execute step 6).

[0140] In the solution of the present invention, by adding this control logic, different adjustments are made to the operating parameters while ensuring the comfort of the air conditioner. For example, when the user sets the temperature to 20°C, when the indoor ambient temperature drops to 23°C or below, the user's demand for cooling is relatively reduced, but the indoor heat exchanger is seriously waterlogged at this time, and the operating frequency of the compressor in the air conditioner needs to be reduced to the lowest frequency. At the same time, by increasing the air volume of the indoor fan, the amount of water attached to the indoor heat exchanger can be quickly reduced.

[0141] Step 6: When the air conditioner runs according to the original operation logic, return to step 2. When the air conditioner running time meets T again, 预设1 When the water discharge information is recorded, the operating status of the air conditioner is adjusted.

[0142] In the scheme of the present invention, a new air conditioner operating logic is added, and a suitable operating logic is selected to reduce the adhesion of condensed water to the indoor heat exchanger and improve the operating efficiency of the air conditioner; wherein, the new operating logic detects the amount of condensed water during the operation of the air conditioner and detects the use environment to adjust the operating state of the air conditioner, reduce the amount of water hanging, and improve the operating efficiency.

[0143] In the solution of the present invention, the drainage speed can also be used as a distinction, and the air conditioner operation state can be adjusted according to the speed. Among them, the drainage speed = drainage volume / drainage time. According to the drainage speed, the water hanging condition of the indoor heat exchanger of the air conditioner is determined. The judgment method is similar to the judgment method based on the cumulative drainage volume P1. At the same time, according to the indoor ambient temperature T 环 With the set temperature T 设 The difference ΔT is used to adjust the operating state of the air conditioner in a manner similar to that based on the accumulated drainage volume P1.

[0144] In some implementations, the control unit 104 increases the operating wind speed of the indoor fan, including any of the following increase situations:

[0145] The first raising situation: the control unit 104 is further configured to control the running wind speed of the indoor fan to maintain the set wind speed if the set wind speed of the indoor fan is greater than or equal to the preset maximum wind speed. For details, see the examples shown in step 411, step 421, step 511, and step 521;

[0146] The second increase situation: the control unit 104 is further configured to control the current value of the operating wind speed of the indoor fan to be increased by one level if the set gear of the operating wind speed of the indoor fan is less than the preset maximum wind speed. For details, please refer to the examples shown in steps 412, 422, 512, and 522.

[0147] In the scheme of the present invention, by judging the condensation water adhesion condition of the indoor heat exchanger and comparing the difference between the real-time temperature of the environment and the temperature set by the user, the operating frequency and the operating gear of the air conditioner are adjusted, so as to reduce the condensation water adhesion condition of the indoor heat exchanger while ensuring the cooling effect of the air conditioner. This solves the problem that the air conditioner cannot effectively reduce the amount of condensation water adhesion on the indoor heat exchanger and the amount of dust adhesion on the indoor heat exchanger during the cooling or dehumidification operation, thereby improving the cooling effect of the air conditioner and improving the comfort of use of the air conditioner.
