Description

Technical Field

[0001] This application relates to the field of airflow dust removal technology, such as a multi-pipe vibration dust removal method, a vibration dust removal device, and an intelligent air conditioner. Background Technology

[0002] Currently, North American countries such as the United States and Canada use ducted split air conditioners for indoor cooling or heating. A ducted split air conditioner consists of an outdoor unit, an indoor unit, and connecting pipes. The indoor unit generates cold / hot air in cooling / heating mode. This air first enters the main supply air duct and then is distributed to various branch supply air ducts. Finally, it enters each room through the air inlet at the end of each branch supply air duct. Simultaneously, each room is equipped with a return air vent, and a corresponding return air duct branch is installed at the return air vent. The air in the room flows from the return air duct branch back to the main return air duct and then enters the indoor unit.

[0003] After prolonged use, dust accumulates in the pipes of an air conditioner. In this case, a vibration device can be installed in the air conditioner pipes. The vibration device can drive the pipes and dust to vibrate, causing the dust to be removed from the pipes and achieving automatic dust removal.

[0004] In the process of implementing the embodiments of this application, at least the following problems were found in the related technology:

[0005] In applications using ducted split air conditioners as an example, there are multiple ducts. If each duct is dusted individually, the total dust removal time will be relatively long. If all ducts are dusted at the same time, the instantaneous power will be relatively high due to the large number of ducts and vibration devices, resulting in more safety hazards.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This application provides a multi-pipe vibration dust removal method, a vibration dust removal device, and an intelligent air conditioner, which can reduce the total dust removal time while ensuring that the instantaneous power meets safety requirements; or, reduce the instantaneous power while ensuring that the total dust removal time meets comfort requirements; or, maintain a balance between the degree to which the total dust removal time meets comfort requirements and the degree to which the instantaneous power meets safety requirements.

[0009] In some embodiments, each pipeline is equipped with one or more vibration devices, and one end of multiple pipelines converges into an air outlet / inlet, where a fan is installed. The multi-pipeline vibration dust removal method includes:

[0010] Start the fan;

[0011] In the current control cycle, the current dust removal power required for each pipeline and the remaining dust removal time corresponding to the current dust removal power are obtained; the current dust removal power is positively correlated with the amount of dust in each pipeline, and the amount of dust in each pipeline is obtained at the end of the previous control cycle; the remaining dust removal time is the vibration time that is negatively correlated with the current dust removal power, which is determined based on the rated dust removal power and the rated dust removal time.

[0012] Based on the current dust removal power, remaining dust removal time, and set power range of each pipeline, multiple pipelines are grouped. The constraints for grouping include: the sum of the current dust removal power of all pipelines in each group is within the set power range, and the remaining dust removal time of each pipeline in each group is adjacent.

[0013] The vibration devices corresponding to each group of pipelines are started one by one, and only one group of pipelines' vibration devices are running at a time. All vibration devices corresponding to each pipeline operate according to the current dust removal power of that pipeline.

[0014] The multi-pipe vibration dust removal method provided in this application embodiment can achieve the following technical effects:

[0015] Dust removal power is generated by the vibration of the vibrating device. Rated dust removal power and rated dust removal duration are used to indicate the expected dust removal operation performed on each pipeline during a single dust removal process. Specifically, for any pipeline, if the actual dust removal power corresponding to that pipeline is higher, then the actual vibration duration corresponding to that pipeline is shorter; if the actual dust removal power corresponding to that pipeline is lower, then the actual vibration duration corresponding to that pipeline is longer.

[0016] The constraints for grouping pipelines are: the sum of the current dust removal power of all pipelines in each group is within the set power range, and the remaining dust removal time of each pipeline in each group is adjacent. Therefore, after controlling multiple pipelines in groups based on their current dust removal power, remaining dust removal time, and set power range, in the last control cycle, the remaining dust removal time of each group's pipelines can finish counting down within a similar timeframe. This reduces the phenomenon where the remaining dust removal time of other pipelines in a group has ended, leaving only a few pipelines with longer remaining dust removal times. It also reduces the time spent on continuous vibration solely for completing dust removal operations on those remaining pipelines. In other words, the vibration time of an entire group can be reduced in the last control cycle. By shortening the time for each group of pipelines in this way, the dust removal time of all pipelines is reduced.

[0017] Based on the premise that the instantaneous power is less than or equal to the safe upper limit power, the upper limit power of the set power range can be made less than or equal to the safe upper limit power. Then, the current dust removal power, the remaining dust removal time and the set power range are grouped together. Multiple pipelines with similar remaining dust removal time are grouped together. Then, according to the analysis process of the last control cycle mentioned above, the total dust removal time is reduced.

[0018] When the total dust removal time is less than or equal to the expected dust removal time to indicate that the total dust removal time meets comfort requirements, the upper limit power of the set power range can be set to a larger value, and the final total dust removal time can be calculated. If the final total dust removal time is greater than the expected dust removal time, the upper limit power of the set power range can be increased until the final total dust removal time is less than or equal to the expected dust removal time; if the final total dust removal time is less than the expected dust removal time, the upper limit power of the set power range can be reduced. That is, when there is a requirement for the total dust removal time, the multi-pipe vibration dust removal method provided in this application embodiment can provide a relatively accurate basis for judging the upper limit power of the set power range. By setting the upper limit value of the set power range with such a basis, there is no need to set a large margin, thereby reducing the instantaneous power.

[0019] Since the multi-pipe vibration dust removal method in this application embodiment can provide a relatively definite correspondence between the total dust removal time and the upper limit power of the set power range, based on this relatively definite correspondence, the balance between the total dust removal time and the upper limit power of the set power range can be adjusted by adjusting the upper limit power of the set power range, so that the final balance between the two meets the user's needs.

[0020] This achieves the following: reducing the total dust removal time while ensuring the instantaneous power meets safety requirements; or reducing the instantaneous power while ensuring the total dust removal time meets comfort requirements; or maintaining a balance between the degree to which the total dust removal time meets comfort requirements and the degree to which the instantaneous power meets safety requirements.

[0021] Furthermore, the multi-pipe vibration dust removal method provided in this application embodiment can achieve better dust removal effect based on different degrees of dust adhesion, and establishes a relatively certain correspondence between the dust removal time and dust removal power required for such dust removal effect, so as to meet the personalized needs of users.

[0022] Optionally, each pipeline may be equipped with two or more vibration devices.

[0023] Optionally, when the vibration device controlling any pipeline starts to vibrate, the vibration frequencies of the two or more vibration devices in that pipeline are not exactly the same.

[0024] This can avoid or reduce resonance between the pipeline and the vibration device, thereby reducing the adverse effects on pipeline fixation.

[0025] Optionally, all vibration devices corresponding to each pipeline operate according to the current dust removal power corresponding to that pipeline, including: controlling two or more vibration devices according to a preset frequency curve corresponding to each vibration device; wherein, when two or more vibration devices vibrate according to the preset frequency curve, the average power of the two or more vibration devices matches the current dust removal power.

[0026] Matching the average power of two or more vibration devices with the current dust removal power means that the power difference between the average power and the current dust removal power is less than or equal to a negligible threshold, which is determined by those skilled in the art based on the actual situation.

[0027] Optionally, multiple pipelines can be grouped according to the current dust removal power, remaining dust removal time, and set power range for each pipeline. This includes using an optimization algorithm to achieve the optimal grouping of multiple pipelines with the goal of minimizing the total power during the dust removal process.

[0028] Using existing optimization algorithms, a grouping method that meets the aforementioned constraints was obtained.

[0029] Optionally, multiple pipelines can be grouped according to the current dust removal power, remaining dust removal time, and set power range for each pipeline. This includes using an optimization algorithm to achieve the optimal grouping of multiple pipelines with the shortest total time during the dust removal process as the optimization objective.

[0030] Using existing optimization algorithms, a grouping method that meets the aforementioned constraints was obtained.

[0031] Optionally, multiple pipelines can be grouped according to the current dust removal power, remaining dust removal time, and set power range corresponding to each pipeline. This includes: sorting all pipelines according to the remaining dust removal time; selecting pipelines sequentially according to the sorting of all pipelines and calculating the current total power of the selected pipelines, ensuring that the current total power is within the set power range, and grouping the selected pipelines as a group.

[0032] This yields a grouping method that meets the aforementioned constraints.

[0033] Optionally, based on the order of all pipelines, pipelines are selected sequentially and the current total power of the selected pipelines is calculated so that the current total power is within the set power range. The selected pipelines are grouped together, including: after selecting pipelines sequentially and grouping the selected pipelines together, another group of pipelines with current total power within the set power range is selected sequentially from the remaining pipelines.

[0034] Optionally, based on the sorting of all pipelines, pipelines are selected sequentially, and the current total power corresponding to the current dust removal power of the selected pipelines is calculated, so that the current total power is within a set power range. The selected pipelines are grouped together, including: when all pipelines are sorted according to the remaining dust removal time in ascending order, after selecting pipelines sequentially and grouping the selected pipelines together, one or more pipelines with the longest remaining time in this group are removed to obtain a portion of the pipelines; one or more pipelines are selected sequentially from the ungrouped pipelines, so that the current total power corresponding to the portion of the pipelines and one or more pipelines is within a set power range, and the portion of the pipelines and one or more pipelines are grouped together as another group.

[0035] This grouping method can reduce the number of control loops.

[0036] Optionally, the determination of the remaining dust removal time includes: for historical control cycles, based on the rated dust removal power and rated dust removal time, converting the historical time corresponding to the historical dust removal power of each pipeline in all historical control cycles into the first standard dust removal time corresponding to the rated dust removal power; and determining the remaining dust removal time based on the time difference between the rated dust removal time and the first standard dust removal time, as well as the current dust removal power.

[0037] Optionally, determining the current dust removal power includes: at the end of the previous control cycle, obtaining the amount of dust in each pipeline using sensors installed in each pipeline; and determining the current dust removal power that is positively correlated with the amount of dust. This allows for a relatively accurate determination of the amount of dust in each pipeline.

[0038] Optionally, determining the current dust removal power includes: recording the amount of dust at the air outlet / inlet when each group of pipes vibrates in the previous control cycle; for any group, obtaining the amount of dust at the air outlet / inlet corresponding to that group of pipes, and dividing it by the quotient of the number of pipes in that group; and determining the current dust removal power that is positively correlated with the quotient.

[0039] This method of obtaining dust levels only requires a single sensor at the air outlet / inlet, eliminating the need for sensors in every duct and reducing the workload required for sensor installation.

[0040] Optionally, determining the current dust removal power includes: recording the amount of dust at the air outlet / air inlet when each group of pipelines vibrates in the previous control cycle; for any group, obtaining the reduction in the amount of dust at the air outlet / air inlet caused by removing one or more pipelines in that group; obtaining the quotient of the reduction in the amount of dust divided by the number of pipelines removed; and determining the current dust removal power that is positively correlated with the quotient.

[0041] This method of obtaining dust levels only requires a single sensor at the air outlet / inlet, eliminating the need for sensors in every duct and reducing the workload required for sensor installation.

[0042] Optionally, switchable filters with different mesh sizes are installed at the air outlet / inlet; starting the fan includes switching from a smaller mesh filter to a larger mesh filter. Switching filters can achieve more effective dust removal.

[0043] Based on the above technical solution, the vibration dust removal method further includes: controlling the fan to stop after the dust removal mode ends; and switching the filter screen with a larger mesh size to a filter screen with a smaller mesh size. This switching reduces the energy consumption of the fan in non-dust removal mode.

[0044] Optionally, the ductwork is a supply air ductwork, or the ductwork is a return air ductwork; the fan is an indoor air conditioning fan with variable airflow direction.

[0045] The indoor unit of the air conditioner is installed in an indoor space. Other rooms without indoor units are connected to the indoor unit through air supply ducts. After heat exchange in the indoor unit, the air enters each room through the air supply ducts. The air in each room enters the indoor unit directly or indirectly through the return air duct.

[0046] When the pipeline is an air supply pipeline, start the fan, including: when switching from cooling mode / heating mode to dust removal mode, stop the fan, and after switching the fan drive direction, start the fan.

[0047] Correspondingly, the multi-pipe vibration dust removal method also includes: after the dust removal mode ends, controlling the fan to stop, and after switching the fan's drive direction, controlling the air conditioner to enter the cooling mode / heating mode.

[0048] Switching the fan's drive direction in this way can prevent dust in the air supply duct from being blown into the room.

[0049] Optionally, in the first control cycle, the current dust removal power required for each pipeline is determined as follows: the total ventilation duration / total ventilation volume of each pipeline from the end of the previous dust removal to the start of the current dust removal is obtained; the current dust removal power that is positively correlated with the total ventilation duration / total ventilation volume is determined to achieve targeted dust removal.

[0050] In some embodiments, each pipeline is provided with one or more vibration devices; one end of multiple pipelines converges into an air outlet / inlet, and a fan is provided at the air outlet / inlet; the multi-pipeline vibration dust removal device includes a fan control module, an acquisition module, a grouping module and a vibration control module.

[0051] The fan control module is used to start the fan;

[0052] The acquisition module is used to obtain the current dust removal power required for each pipeline and the remaining dust removal time corresponding to the current dust removal power in the current control cycle; the current dust removal power is positively correlated with the amount of dust in each pipeline, and the amount of dust in each pipeline is obtained at the end of the previous control cycle; the remaining dust removal time is a dust removal time that is negatively correlated with the current dust removal power, based on the rated dust removal power and the rated dust removal time.

[0053] The grouping module is used to group multiple pipelines according to the current dust removal power, remaining dust removal time and set power range of each pipeline. The constraints of grouping include: the sum of the current dust removal power of all pipelines in each group is within the set power range, and the remaining dust removal time of each pipeline in each group is adjacent.

[0054] The vibration control module is used to start the vibration device corresponding to each group of pipelines one by one, and only one group of pipelines' vibration devices can be running at a time. All vibration devices corresponding to each pipeline work according to the current dust removal power of that pipeline.

[0055] Similarly, this multi-pipe vibration dust collector can reduce the total dust collection time while ensuring that the instantaneous power meets safety requirements; or, reduce the instantaneous power while ensuring that the total dust collection time meets comfort requirements; or, maintain a balance between the degree to which the total dust collection time meets comfort requirements and the degree to which the instantaneous power meets safety requirements.

[0056] In some embodiments, a multi-pipe vibration dust removal device includes a processor and a memory storing program instructions, the processor being configured to execute the multi-pipe vibration dust removal method provided in the foregoing embodiments when executing the program instructions.

[0057] In some embodiments, the smart air conditioner includes:

[0069] To provide a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this application. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0071] Unless otherwise stated, the term "multiple" means two or more.

[0072] In this embodiment, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0073] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0074] Figure 1This is a schematic diagram of an implementation scenario of a ducted split air conditioner provided in an embodiment of this application.

[0075] Combination Figure 1 As shown, the indoor unit 11 of the air conditioner is usually installed in an indoor space, and is usually concealed, for example, it can be installed in the indoor ceiling 14, which can save the machine room area.

[0076] The indoor unit 11 of the air conditioner is connected to other rooms 15 without an indoor unit 11 through the air supply duct 12. After the air undergoes heat exchange in the indoor unit 11, it enters each room 15 through the air supply duct 12. An air valve is installed at the end of the air supply duct 12 in each room 15. By adjusting the opening of the air valve, the air volume entering the room 15 can be adjusted, thereby adjusting the indoor temperature.

[0077] The indoor unit 11 of the air conditioner absorbs air from each room 15 through the return air duct 13, and the air in the return air duct 13 and the supply air duct 12 exchange heat inside the indoor unit 11.

[0078] The cooling / heating principle of the ducted split air conditioner is similar to that of the ordinary split air conditioner. It consists of an indoor unit 11 and an outdoor unit (not shown in the figure), which are connected by copper pipes during installation.

[0079] The static pressure at the air outlet of the indoor unit 11 of a ducted split air conditioner is higher than that at the air outlet of the indoor unit of a regular split air conditioner; the single unit capacity of a ducted split air conditioner is also relatively large, generally available in various specifications such as 5 horsepower, 8 horsepower, 10 horsepower, and 12.5 horsepower; the length of the copper pipe that can be connected between the indoor unit 11 and the outdoor unit of a ducted split air conditioner is also longer, generally up to 50m, and the height difference between the indoor and outdoor units can reach 20m.

[0080] The vibration device 16 can be installed in the air supply duct 12, or the vibration device 16 can be installed in the return air duct 13 (not shown in the figure), or the vibration device 16 can be installed in both the air supply duct 12 and the return air duct 13 (not shown in the figure).

[0081] The vibration device 16 can be installed on the inside or outside of a pipeline and fixed relative to the pipeline. When the vibration device 16 vibrates, it can drive the pipeline to vibrate simultaneously.

[0082] In this application embodiment, the term "air volume" is used to represent the amount of air flowing per unit time, and its unit can be m. 3 / h、m 3 / min, L / h, L / min, etc.

[0083] This application uses a ducted split air conditioner as an example for illustrative purposes. This multi-pipe vibration dust removal method can also be applied to other scenarios with the necessary hardware, such as central air conditioning.

[0084] Figure 2 This is a schematic flowchart of a multi-pipe vibration dust removal method provided in an embodiment of this application.

[0085] Each pipeline is equipped with one or more vibration devices, and one end of multiple pipelines converges into an air outlet / inlet, where a fan is installed.

[0086] The multi-pipe vibration dust removal method can be implemented through a fan controller. When the fan is a fan in a specific device, the multi-pipe vibration dust removal method can be implemented through the controller of the specific device. For example, when the fan is an indoor fan of an air conditioner, the multi-pipe vibration dust removal method can be implemented through the controller of the air conditioner. Even in a smart home system, the multi-pipe vibration dust removal method can be executed through the server of the smart home system.

[0087] Combination Figure 2 As shown, the multi-pipe vibration dust removal method includes:

[0088] S201, Start the fan.

[0089] In the first control cycle, the fan can be started after the piping grouping is determined.

[0090] In any control cycle, when switching pipeline groups, the fan can be shut down first, then the pipeline group can be switched, and then the fan can be restarted; alternatively, the pipeline group can be switched while the fan is running continuously.

[0091] Pipelines are typically equipped with dampers, which are used to switch between different sections of the pipeline by controlling their opening and closing. When a damper is open, the corresponding pipeline is ventilated; when a damper is closed, the corresponding pipeline is not ventilated. During dust removal of a particular pipeline, the damper corresponding to that pipeline is opened; otherwise, it is closed.

[0092] The performance of the air valve meets the requirements, specifically: when the air valve is closed, the air valve meets the common air-leakage judgment criteria in the field, and the impact of air leakage from the air valve can be disregarded.

[0093] During the switching between two control cycles, the fan can be shut down first to switch control cycles, and then the fan can be restarted; alternatively, the current control cycle can be switched to the next control cycle while the fan is running continuously.

[0094] S202. In the current control cycle, obtain the current dust removal power required for each pipeline, and the remaining dust removal time corresponding to the current dust removal power.

[0095] The current dust removal power is positively correlated with the amount of dust in each pipeline, and the amount of dust in each pipeline is obtained at the end of the previous control cycle.

[0096] Optionally, determining the current dust removal power includes: at the end of the previous control cycle, obtaining the amount of dust in each pipeline using sensors installed in each pipeline; and determining the current dust removal power that is positively correlated with the amount of dust. This allows for a relatively accurate determination of the amount of dust in each pipeline.

[0097] Optionally, determining the current dust removal power includes: recording the amount of dust at the air outlet / inlet when each group of pipes vibrates in the previous control cycle; for any group, obtaining the amount of dust at the air outlet / inlet corresponding to that group of pipes, and dividing it by the quotient of the number of pipes in that group; and determining the current dust removal power that is positively correlated with the quotient.

[0098] This method of obtaining dust levels only requires a single sensor at the air outlet / inlet, eliminating the need for sensors in every duct and reducing the workload required for sensor installation.

[0099] Optionally, determining the current dust removal power includes: recording the amount of dust at the air outlet / air inlet when each group of pipelines vibrates in the previous control cycle; for any group, obtaining the reduction in the amount of dust at the air outlet / air inlet caused by removing one or more pipelines in that group; obtaining the quotient of the reduction in the amount of dust divided by the number of pipelines removed; and determining the current dust removal power that is positively correlated with the quotient.

[0100] This method of obtaining dust levels only requires a single sensor at the air outlet / inlet, eliminating the need for sensors in every duct and reducing the workload required for sensor installation.

[0101] The aforementioned remaining dust removal time is a dust removal time that is negatively correlated with the current dust removal power, based on the rated dust removal power and rated dust removal time.

[0102] The reference for rated dust removal power and rated dust removal duration refers to the rated dust removal power and rated vibration duration.

[0103] Based on the rated dust removal power and rated dust removal time, the higher the actual dust removal power, the shorter the actual dust removal time; the lower the actual dust removal power, the longer the actual dust removal time.

[0104] The rated dust removal power and rated dust removal time are determined based on the degree of dust adhesion to the pipes.

[0105] Different types of dust adhere to pipes to varying degrees. For example, the ash from burning paper and the ash from cooking oil adhere to pipes differently; the ash from burning paper adheres to pipes less than the ash from cooking oil. The example of cooking oil listed here is merely to illustrate that different types of dust adhere to pipes to varying degrees.

[0106] Dust of the same type but in different states will adhere to pipes to varying degrees. For example, dust with different levels of humidity will adhere to pipes to varying degrees; the higher the humidity of the dust, the greater its adhesion to the pipes.

[0107] In a certain control cycle of the dust removal process, the higher the degree of dust adhesion to the pipeline, the smaller the amount of dust falling off in that control cycle, and the smaller the amount of dust that can be measured in the pipeline; the lower the degree of dust adhesion to the pipeline, the larger the amount of dust falling off in that control cycle, and the larger the amount of dust that can be measured in the pipeline in that control cycle.

[0108] In this embodiment, if the amount of dust measured in the previous control cycle is large, the current dust removal power of the pipeline is increased. Based on the rated dust removal power and rated dust removal time, the actual dust removal time of the pipeline is shorter, and the remaining dust removal time is also shorter. This can remove dust with low adhesion in the pipeline.

[0109] If the dust level measured in the previous control cycle is low, the current dust removal power of the pipeline is set to be low, based on the rated dust removal power and rated dust removal time. Therefore, the actual dust removal time of the pipeline is longer, and the remaining dust removal time is also longer. This can effectively remove highly adherent dust from the pipeline.

[0110] Through the above process, the multi-pipe vibration dust removal method provided in this application embodiment can achieve better dust removal effect based on different degrees of dust adhesion. Furthermore, it establishes a relatively definite correspondence between the dust removal time and dust removal power required for such a dust removal effect, so as to meet the user's personalized needs, such as the need for total dust removal time, the need for instantaneous power, and the need for a balance between total dust removal time and instantaneous power.

[0111] Optionally, the determination of the remaining dust removal time includes: for historical control cycles, based on the rated dust removal power and rated dust removal time, converting the historical time corresponding to the historical dust removal power of each pipeline in all historical control cycles into the first standard dust removal time corresponding to the rated dust removal power; and determining the remaining dust removal time based on the time difference between the rated dust removal time and the first standard dust removal time, as well as the current dust removal power.

[0112] S203. Group multiple pipelines according to the current dust removal power, remaining dust removal time, and set power range corresponding to each pipeline.

[0113] The constraints for grouping include: the sum of the current dust removal power of all pipelines in each group is within the set power range, and the remaining dust removal time of each pipeline in each group is adjacent.

[0114] The remaining dust removal time corresponding to each pipeline in each group is adjacent, which means that after all pipelines are sorted by length, two remaining dust removal times are adjacent to each other in the sorting.

[0115] Optionally, multiple pipelines can be grouped according to the current dust removal power, remaining dust removal time, and set power range for each pipeline. This includes using an optimization algorithm to achieve the optimal grouping of multiple pipelines with the goal of minimizing the total power during the dust removal process.

[0116] Using existing optimization algorithms, a grouping method that meets the aforementioned constraints was obtained.

[0117] Optionally, multiple pipelines can be grouped according to the current dust removal power, remaining dust removal time, and set power range for each pipeline. This includes using an optimization algorithm to achieve the optimal grouping of multiple pipelines with the shortest total time during the dust removal process as the optimization objective.

[0118] Using existing optimization algorithms, a grouping method that meets the aforementioned constraints was obtained.

[0119] S204. Start the vibration device corresponding to each group of pipelines one by one, and only one group of pipelines' vibration devices can be running at a time.

[0120] All vibration devices corresponding to each pipeline operate according to the current dust removal power of that pipeline.

[0121] The multi-pipe vibration dust removal method provided in this application requires the execution of multiple control cycles. This means that during the process of starting the vibration device corresponding to each group of pipes one by one, the vibration device of each group of pipes runs for a certain period of time. This certain period of time can be determined by those skilled in the art based on their own experience.

[0122] The multi-pipe vibration dust removal method provided in this application embodiment can achieve the following technical effects:

[0123] Dust removal power is generated by the vibration of the vibrating device. Rated dust removal power and rated dust removal duration are used to indicate the expected dust removal operation performed on each pipeline during a single dust removal process. Specifically, for any pipeline, if the actual dust removal power corresponding to that pipeline is higher, then the actual vibration duration corresponding to that pipeline is shorter; if the actual dust removal power corresponding to that pipeline is lower, then the actual vibration duration corresponding to that pipeline is longer.

[0124] The constraints for grouping pipelines are: the sum of the current dust removal power of all pipelines in each group is within the set power range, and the remaining dust removal time of each pipeline in each group is adjacent. Therefore, after controlling multiple pipelines in groups based on their current dust removal power, remaining dust removal time, and set power range, in the last control cycle, the remaining dust removal time of each group's pipelines can finish counting down within a similar timeframe. This reduces the phenomenon where the remaining dust removal time of other pipelines in a group has ended, leaving only a few pipelines with longer remaining dust removal times. It also reduces the time spent on continuous vibration solely for completing dust removal operations on those remaining pipelines. In other words, the vibration time of an entire group can be reduced in the last control cycle. By shortening the time for each group of pipelines in this way, the dust removal time of all pipelines is reduced.

[0125] Based on the premise that the instantaneous power is less than or equal to the safe upper limit power, the upper limit power of the set power range can be made less than or equal to the safe upper limit power. Then, the current dust removal power, the remaining dust removal time and the set power range are grouped together. Multiple pipelines with similar remaining dust removal time are grouped together. Then, according to the analysis process of the last control cycle mentioned above, the total dust removal time is reduced.

[0126] When the total dust removal time is less than or equal to the expected dust removal time to indicate that the total dust removal time meets comfort requirements, the upper limit power of the set power range can be set to a larger value, and the final total dust removal time can be calculated. If the final total dust removal time is greater than the expected dust removal time, the upper limit power of the set power range can be increased until the final total dust removal time is less than or equal to the expected dust removal time; if the final total dust removal time is less than the expected dust removal time, the upper limit power of the set power range can be reduced. That is, when there is a requirement for the total dust removal time, the multi-pipe vibration dust removal method provided in this application embodiment can provide a relatively accurate basis for judging the upper limit power of the set power range. By setting the upper limit value of the set power range with such a basis, there is no need to set a large margin, thereby reducing the instantaneous power.

[0127] The above process involves determining the upper limit of the set power range through experimentation. After those skilled in the art have used the multi-pipe vibration dust removal method multiple times and accumulated certain experience, they can determine an approximate power range for the upper limit of the set power range based on experience, so as to set the power range more quickly.

[0128] Since the multi-pipe vibration dust removal method in this application embodiment can provide a relatively definite correspondence between the total dust removal time and the upper limit power of the set power range, based on this relatively definite correspondence, the balance between the total dust removal time and the upper limit power of the set power range can be adjusted by adjusting the upper limit power of the set power range, so that the final balance between the two meets the user's needs.

[0129] This achieves the following: reducing the total dust removal time while ensuring the instantaneous power meets safety requirements; or reducing the instantaneous power while ensuring the total dust removal time meets comfort requirements; or maintaining a balance between the degree to which the total dust removal time meets comfort requirements and the degree to which the instantaneous power meets safety requirements.

[0130] Optionally, each pipeline may be equipped with two or more vibration devices.

[0131] Optionally, when the vibration device controlling any pipeline starts to vibrate, the vibration frequencies of the two or more vibration devices in that pipeline are not exactly the same.

[0132] This can avoid or reduce resonance between the pipeline and the vibration device, thereby reducing the adverse effects on pipeline fixation.

[0133] Optionally, when two or more vibration devices are installed in each pipeline, all vibration devices corresponding to each pipeline operate according to the current dust removal power of the pipeline, including: controlling two or more vibration devices according to the preset frequency curve corresponding to each vibration device; wherein, when two or more vibration devices vibrate according to the preset frequency curve, the average power of the two or more vibration devices matches the current dust removal power.

[0134] Matching the average power of two or more vibration devices with the current dust removal power means that the power difference between the average power and the current dust removal power is less than or equal to a negligible threshold, which is determined by those skilled in the art based on the actual situation.

[0143] Optionally, based on the order of all pipelines, pipelines are selected sequentially and the current total power of the selected pipelines is calculated so that the current total power is within the set power range. The selected pipelines are grouped together, including: after selecting pipelines sequentially and grouping the selected pipelines together, another group of pipelines with current total power within the set power range is selected sequentially from the remaining pipelines.

[0144] Optionally, based on the sorting of all pipelines, pipelines are selected sequentially, and the current total power corresponding to the current dust removal power of the selected pipelines is calculated, so that the current total power is within a set power range. The selected pipelines are grouped together, including: when all pipelines are sorted according to the remaining dust removal time in ascending order, after selecting pipelines sequentially and grouping the selected pipelines together, one or more pipelines with the longest remaining time in this group are removed to obtain a portion of the pipelines; one or more pipelines are selected sequentially from the ungrouped pipelines, so that the current total power corresponding to the portion of the pipelines and one or more pipelines is within a set power range, and the portion of the pipelines and one or more pipelines are grouped together as another group.

[0145] This grouping method can reduce the number of control loops.

[0146] This grouping method is a rolling grouping, or a sliding window grouping. It is typically used when the remaining dust removal time varies significantly across multiple pipes; however, it can also handle situations where the remaining dust removal time varies only slightly across multiple pipes.

[0147] S305. Start the vibration device corresponding to each group of pipelines one by one, and only one group of pipelines can operate at a time.

[0148] All vibration devices corresponding to each pipeline operate according to the current dust removal power of that pipeline.

[0163] Optionally, controlling the air conditioner to enter cooling / heating mode includes: stopping the fan; switching from a larger mesh filter to a smaller mesh filter before controlling the air conditioner to enter cooling / heating mode.

[0164] Optionally, controlling the air conditioner to enter cooling / heating mode includes: stopping the fan, and then switching the fan's drive direction before switching the air conditioner to cooling / heating mode.

After the frosting and defrosting process of the air conditioner indoor unit is completed, the dust removal mode is determined to be over, and then the air conditioner is controlled to enter the cooling mode / heating mode.
