Description

Technical Field

[0001] This invention relates to the field of central air conditioning technology, and more specifically, to an energy-saving central air conditioning system. Background Technology

[0002] Central air conditioning is a self-contained, miniaturized air conditioning system consisting of one or more cold / heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the necessary cooling capacity to offset the heat load of the indoor environment; simultaneously, the heating system provides the necessary heat to offset the heating / cooling load of the indoor environment. During operation, central air conditioning systems draw fresh air from the outside into the room. After the fresh air is drawn into the fresh air duct, it needs to be filtered, using filter panels to remove dust and impurities. However, after prolonged operation, a large amount of dust and impurities will accumulate on the side of the filter panel facing the fresh air inlet, affecting not only the filtration effect but also the air intake volume.

[0003] While some automatic dust removal methods exist in existing technologies to address the tediousness of manual cleaning, these methods still have significant drawbacks. They cannot proactively determine the timing of dust removal. This means that either the dust removal operation might be performed before the dust on the filter plate has accumulated to the point of affecting the filtration effect and air intake, resulting in unnecessary energy and resource waste, or the dust removal might be performed only after a severe accumulation of dust, causing the performance of the air conditioning system to be affected for some time prior. On the other hand, even with some automatic dust removal and dust collection measures, the collected dust may still fall into the air conditioner due to various reasons (such as airflow disturbances, vibrations of the dust removal device, etc.). Once the dust enters the air conditioner, it may damage various components such as the compressor, evaporator, and condenser, affecting their normal operation and even shortening the service life of the air conditioner.

[0004] How to invent an energy-efficient central air conditioning system to solve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0005] To overcome the above deficiencies, the present invention provides an energy-saving central air conditioning system, which aims to solve the problems mentioned in the background.

[0006] This invention is implemented as follows: This invention provides an energy-saving central air conditioner, including an air conditioner body and a duct disposed at the lower end of the air conditioner body, wherein the air inlet end of the duct is provided with a filter screen, and further comprising: Adjustable air intake assembly: The adjustable air intake assembly is installed on the duct and located behind the filter screen; The induction dust collection component is disposed between the filter screen and the regulating air intake component; Cleaning and collection components: The cleaning and collection components are located inside and at the bottom of the pipe.

[0009] Preferably, the inductive dust collection assembly includes a connecting plate, an adsorption plate, an inductive rod, and a movable groove on the bottom wall of the pipe. A limiting rod is fixedly installed inside the movable groove. Several connecting rings and retaining sleeves are rotatably sleeved on the limiting rod. The connecting rings and retaining sleeves are alternately distributed. The lower end of the connecting plate is fixedly connected to the side wall of the connecting ring. An elastic part is fixedly connected to the upper end of the connecting plate. A ball is fixedly connected to the upper end of the elastic part. An adsorption plate is fixedly connected to the ball. The connecting plate and the side wall of the filter screen are elastically connected by a spring.

[0010] Preferably, the inner wall of the pipe is symmetrically fitted with sleeves that limit the two ends of the sensing rod, the adsorption plate is located in the middle of the sphere, the end of the sphere in the initial state of the spring abuts against the side wall of the filter screen plate, there is a gap between the adsorption plate and the filter screen plate, and several connecting plates are equidistantly distributed.

[0011] Preferably, the sensing rod is located on the rear side of the elastic part, and the side wall of the elastic part facing the sensing rod is provided with a magnetic coating. A plurality of Hall sensors are provided on the sensing rod corresponding to the elastic part, and the plurality of Hall sensors are electrically connected to the sensing rod. An electrostatic adsorption coating is provided on one side of the adsorption plate facing the filter screen plate. The adsorption plate is arranged in a long strip shape, and there are gaps between adjacent adsorption plates.

[0012] Preferably, the cleaning and collection assembly includes an air guide box, a filter bag, a magnetic blocking plate, and a ash discharge port on the bottom wall of the pipe. A mounting groove is provided in the bottom wall of the pipe corresponding to the ash discharge port. An electromagnet is fixedly installed in the mounting groove near the filter screen plate, and a spring is fixedly connected in the mounting groove away from the filter screen plate. The end of the spring is fixedly connected to one side of the magnetic blocking plate. Several pressure rods are fixedly connected to the side of the magnetic blocking plate facing the filter screen plate. Through holes matching the pressure rods are provided inside the electromagnet and the bottom wall of the pipe. The end of the through hole located in the bottom wall of the pipe penetrates the side wall of the mounting groove and the movable groove. The air guide box is slidably disposed inside the pipe. The interior of the air guide box is hollow. Limiting sliders are fixedly connected to both the upper and lower ends of the air guide box. A sliding groove matching the limiting slider is opened on the inner wall of the pipe. The end of the sliding groove on the lower side penetrates the bottom wall of the pipe. A second motor is fixedly installed on the inner top wall of the air guide box. The output end of the second motor penetrates the top wall of the air guide box and a gear is fixedly connected to its end. A rack that meshes with the gear is fixedly installed on the top of the filter screen plate facing the air guide box. An air pump is installed on the side wall of the air guide box away from the filter screen plate. The air pump's air delivery end is located inside the air guide box.

[0013] Preferably, a magnetic frame is fixedly connected to the upper side of the cloth bag, and the cloth bag is magnetically attracted to the bottom wall of the pipe through the magnetic frame. A positioning block for limiting the magnetic frame is fixedly installed on the bottom wall of the pipe. The cloth bag can completely cover the chute and the ash discharge port. An air guide groove is provided through one side of the air guide box facing the filter screen plate, and the end of the air guide groove abuts against the side wall of the filter screen plate.

[0014] Preferably, the top of the sliding groove and the top of the movable groove near the filter screen are both chamfered, and the end section of the pressure rod facing the filter screen is arc-shaped.

[0015] Preferably, the sensing rod, motor one, air pump, electromagnet and motor two are electrically connected. When the electromagnet is energized, the opposite surfaces of the electromagnet and the magnetic blocking plate are magnetically set with the same polarity. When the electromagnet is not energized, the magnetic blocking plate completely blocks the ash discharge port and the end of the pressure rod abuts against the side wall of the connecting plate. When the electromagnet is energized, the ash discharge port is in the open state and the baffle completely blocks the pipe.

[0016] The beneficial effects of this invention are: 1. The induction dust collection component utilizes the electrostatic adsorption function of the adsorption plate to effectively capture tiny dust particles in the air, further purifying the air. Simultaneously, through the cooperation of the elastic element, magnetic coating, and Hall sensor, it can accurately detect the degree of dust accumulation on the filter screen, promptly identify localized blockages, and provide timely feedback signals to the control system. This prevents excessive dust accumulation from affecting the air intake quality and normal operation of the air conditioning system. The adsorption plate, working in conjunction with the elastic element, magnetic coating, and Hall sensor, provides feedback on the filter screen's blockage status, informing the system whether to activate the cleaning and collection component. Furthermore, the adsorption plate effectively adsorbs tiny dust particles in the air using electrostatic adsorption principles; even small impurities that the filter screen fails to intercept can be captured by the adsorption plate, further improving the cleanliness of the air entering the air conditioning system.

[0017] 2. By combining wind-powered cleaning and tapping cleaning, the filter screen and adsorption plate are thoroughly cleaned to ensure the cleanliness of the air intake, which helps improve the air conditioner's efficiency and cooling / heating performance. During the cleaning process, the baffle of the air intake component is adjusted to completely block the pipes, acting as a wall to prevent dust from entering the air conditioner or the room. The dust discharge port of the cleaning collection component is sealed by a magnetic blocking plate when not cleaning to prevent dust leakage. At the same time, the position of the connecting plate is limited by the pressure rod, ensuring the monitoring accuracy of the sensing rod, increasing the stability of components such as the adsorption plate and elastic part, reducing their shaking amplitude during air conditioner operation, preventing dust from falling off prematurely due to vibration, and ensuring that the adsorption plate and filter screen can continuously and effectively adsorb dust until the set cleaning conditions are met.

[0018] 3. The baffle, connected to components such as incomplete gears, controls the pipe opening. During dust removal, the air pump starts and blows away the dust. The baffle seals the pipe, acting as a wall to prevent dust from entering the air conditioner or the room. This ensures that dust is collected in the pipe and enters the filter bag through the ash discharge port, preventing overflow. It also guides the dust towards the ash discharge port, improving collection efficiency, reducing dust residue in the pipe, keeping the pipe clean, and facilitating the long-term stable operation of the air conditioning system. The air intake adjustment component automatically adjusts the baffle opening and closing based on indoor temperature and humidity, controlling the air intake. When the indoor heat and humidity load is low, the air intake is reduced to lower energy consumption; when the load is high, the air intake is increased to improve cooling or dehumidification effects. This prevents the air conditioner from operating at high air volume under low load, improving energy utilization efficiency and achieving energy saving. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, Example 1, refer to Figures 1-8 An energy-saving central air conditioning system includes an air conditioning unit 10 and a duct 1 located at the lower end of the air conditioning unit 10. The duct 1 serves as an air transport channel. A filter plate 2 is installed at the air inlet end of the duct 1. The main function of the filter plate 2 is to perform preliminary filtration of the air entering the air conditioning system. It can intercept larger particles of impurities such as dust, hair, and fibers in the air, preventing these impurities from entering the interior of the air conditioning unit 10 and avoiding damage to components such as the compressor, evaporator, and condenser. This extends the service life of the air conditioning system. Furthermore, the internal components of the air conditioning system are less prone to dust accumulation, thereby reducing the frequency and workload of cleaning and maintenance, and lowering maintenance costs. The system also includes: Adjustable air intake assembly: The adjustable air intake assembly is installed on the duct 1 and located behind the filter screen 2; The dust collection sensor is positioned between the filter screen 2 and the air intake regulating component. Cleaning and collecting components: Cleaning and collecting components are located inside and at the bottom of pipe 1.

[0024] Furthermore, the air intake adjustment assembly includes a motor 5, a main gear 51, two incomplete gears 53, and a baffle 54. The motor 5 is fixed on the inner wall of the pipe 1. The output end of the motor 5 passes through the side wall of the pipe 1 and its end is fixedly connected to the main gear 51. A secondary gear 52 that meshes with the main gear 51 is rotatably connected to the outer wall of the pipe 1. A connecting rod 540 is fixedly connected to one end of the baffle 54, and an elastic plug 541 is fixedly connected to the other end. The end of the connecting rod 540 passes through the side wall of the pipe 1, and its end is fixedly connected to the incomplete gear 53. The upper incomplete gear 53 meshes with the secondary gear 52, and the lower incomplete gear 53 meshes with the main gear 51. That is, the main gear 51 drives the lower incomplete gear 53 to rotate, and the secondary gear 52 drives the upper incomplete gear 53 to rotate.

[0025] It should be noted that the two baffles 54 are symmetrically distributed along the center line of the pipe 1. The opening and closing of the baffles 54 can be controlled by the rotation of the incomplete gear 53, thereby adjusting the air intake in the pipe 1. The motor 5 is electrically connected to the pipe 1, the indoor temperature sensor, and the humidity sensor. This allows the motor 5 to automatically adjust the air intake according to the indoor temperature and humidity. When the indoor temperature or humidity is high, the motor 5 drives the main gear 51 and the auxiliary gear 52 to rotate, causing the baffles 54 to open and increasing the air intake to improve the cooling or dehumidification effect of the air conditioner. When the indoor temperature or humidity is low, the motor 5 controls the baffles 54 to close or reduce the opening, reducing the air intake, reducing energy consumption, and achieving energy saving. The main gear 51 and the auxiliary gear 52 are of the same specification, which can ensure a transmission ratio of 1:1, making the power transmission stable.

[0026] In this embodiment, when the motor 5 is powered on and started, the main gear 51 begins to rotate. Since the main gear 51 meshes with the secondary gear 52 and the main gear 51 and secondary gear 52 are of the same specifications (transmission ratio of 1:1), the rotation of the main gear 51 will drive the secondary gear 52 to rotate at the same speed but in the opposite direction. The main gear 51 drives the lower incomplete gear 53 to rotate, and the secondary gear 52 drives the upper incomplete gear 53 to rotate. One end of the baffle 54 is fixedly connected to the incomplete gear 53 through the connecting rod 540, and the other end is provided with an elastic plug 541. As the incomplete gear 53 rotates, it will drive the baffle 54 to rotate around its connection point with the pipe 1 through the connecting rod 540, thereby controlling the opening and closing state of the baffle 54.

[0027] Indoor temperature and humidity sensors monitor indoor temperature and humidity data in real time and feed this data back to the control system of motor 5. When the indoor temperature or humidity is high, the control system will control motor 5 to start and reverse, driving the main gear 51 and the auxiliary gear 52 to rotate, thereby opening the two baffles 54, increasing the air intake in the duct 1, so that the air conditioner body 10 can draw in more air for cooling or dehumidification, improving the cooling or dehumidification effect. When the indoor temperature or humidity is low, the control system will control motor 5 to rotate forward, causing the baffles 54 to close or reduce their opening, reducing the air intake, reducing the energy consumption of the air conditioning system, and achieving energy-saving operation.

[0028] When the baffle 54 is in the closed state, the elastic plug 541 can tightly fit the plug of the other baffle 54. Due to its elasticity, it can fill the tiny gaps caused by insufficient processing precision or long-term use, effectively preventing air from leaking from the gap between the baffle 54 and the pipe 1. This helps to improve the energy efficiency of the air conditioning system, because reducing air leakage means that the air conditioner does not need to consume extra energy to compensate for the leaked air volume, thus avoiding energy waste. At the same time, during the process of the baffle 54 closing or opening, the elastic plug 541 can play a buffering role. When the baffle 54 moves quickly and comes into contact with the inner wall of the pipe 1 or other components, the elastic plug 541 can absorb some of the impact force and reduce the noise generated by the collision. This is especially important for places that require a quiet environment (such as offices, bedrooms, etc.) and can improve the user experience.

[0029] By automatically adjusting the air intake volume according to the actual indoor temperature and humidity, the air conditioner avoids operating at a large air volume when the indoor load is low, thereby reducing unnecessary energy consumption, improving the energy utilization efficiency of the air conditioning system, and achieving the goal of energy saving. For example, at night or when there are fewer people indoors, the indoor heat and humidity load is low, and the system can automatically reduce the air intake volume, reduce the operating power of the air conditioner, and save electricity.

[0030] Example 2, refer to Figures 4-9The induction dust collection assembly includes a connecting plate 7, an adsorption plate 73, an induction rod 8, and a movable groove 76 on the bottom wall of the pipe 1. A limiting rod 77 is fixedly installed inside the movable groove 76. Several connecting rings 70 and retaining sleeves 75 are rotatably sleeved on the limiting rod 77. The connecting rings 70 and retaining sleeves 75 are alternately distributed. The retaining sleeves 75 ensure a suitable gap between the connecting plates 7, allowing air to pass smoothly; on the other hand, they limit and protect the connecting rings 70, preventing them from shifting during rotation. Axial movement is achieved by fixing the lower end of the connecting plate 7 to the side wall of the connecting collar 70, allowing the connecting plate 7 to rotate around the limiting rod 77. An elastic part 71 is fixedly connected to the upper end of the connecting plate 7, and a ball 72 is fixedly connected to the upper end of the elastic part 71. An adsorption plate 73 is fixedly connected to the ball 72. The connecting plate 7 and the side wall of the filter screen 2 are elastically connected by a spring 2 74. During airflow, the elastic part 71 acts as a buffer, reducing the shaking of the adsorption plate 73 caused by airflow impact, and ensuring the stability and adsorption effect of the adsorption plate 73.

[0031] Furthermore, the inner wall of the pipe 1 is symmetrically equipped with clamps 81 that limit the two ends of the sensing rod 8. The adsorption plate 73 is located in the middle of the ball 72. The end of the ball 72 in the initial state of the spring 74 abuts against the side wall of the filter screen plate 2. There is a gap between the adsorption plate 73 and the filter screen plate 2 to ensure that the adsorption plate 73 does not affect the normal flow of air and can play an adsorption role in time when dust enters. Several connecting plates 7 are evenly distributed so that the adsorption plate 73 can be evenly distributed in the pipe 1, thereby more comprehensively adsorbing dust in the air passing through the filter screen plate 2, improving the dust collection effect, and avoiding the situation of poor local dust collection effect.

[0032] It should be noted that the sensing rod 8 is located behind the elastic part 71. The side wall of the elastic part 71 facing the sensing rod 8 is provided with a magnetic coating. Several Hall sensors are provided on the sensing rod 8 corresponding to the elastic part 71. The Hall sensors are electrically connected to the sensing rod 8. When the air conditioner is turned on, under the action of wind, the adsorption plate 73 will cause the elastic part 71 to deform. The distance between the magnetic coating and the Hall sensors changes. The Hall sensors can detect the change in magnetic field strength, thereby judging the degree of dust accumulation on the filter plate 2. When the filter plate 2 is partially blocked, the airflow in that part decreases, the deformation of the corresponding elastic part 71 decreases, and the magnetic field strength monitored by the Hall sensor at the corresponding location also decreases accordingly. When the dust accumulates to a certain extent, a feedback signal is sent in time to activate the cleaning and collection component for cleaning, ensuring the air intake quality and normal operation of the air conditioning system.

[0033] An electrostatic adsorption coating is provided on one side of the adsorption plate 73 facing the filter screen 2. Utilizing the principle of electrostatic adsorption, it can more effectively adsorb tiny dust particles in the air. Even some small impurities that are difficult to be intercepted by the filter screen 2 can be captured by the adsorption plate 73, further improving the cleanliness of the air. The adsorption plate 73 is arranged in a long strip shape, which increases the contact area with the air and helps to improve the dust adsorption capacity. There are gaps between adjacent adsorption plates 73, which not only ensures the air circulation but also avoids mutual interference between the adsorption plates 73, ensuring that each adsorption plate 73 can work independently and effectively.

[0034] In this embodiment, when the air conditioner is turned on, air enters from the air inlet of the duct 1, undergoes preliminary filtration by the filter screen 2, and then continues to flow through the area of ​​the adsorption plate 73. The side of the adsorption plate 73 facing the filter screen 2 is provided with an electrostatic adsorption coating. Utilizing the principle of electrostatic adsorption, it can adsorb tiny dust particles remaining in the air. Even small impurities that the filter screen 2 fails to intercept will be captured by the adsorption plate 73. Since the adsorption plate 73 is elongated and several connecting plates 7 are evenly distributed, the adsorption plate 73 is evenly distributed in the duct 1, increasing the contact area with the air, thereby more comprehensively adsorbing dust from the air. There are gaps between adjacent adsorption plates 73, ensuring that the air can pass smoothly, while avoiding mutual interference between the adsorption plates 73, ensuring that each adsorption plate 73 can work independently and effectively.

[0035] During airflow, the adsorption plate 73 is impacted by airflow and its weight increases due to adsorbed dust. This causes the connected elastic part 71 to deform. When the elastic part 71 deforms, the distance between the magnetic coating and the Hall sensor changes. The Hall sensor can detect changes in magnetic field strength. When there is little dust accumulation on the filter plate 2, the airflow is smooth, the airflow impact force on the adsorption plate 73 is relatively stable, the deformation of the elastic part 71 is small, and the magnetic field strength detected by the Hall sensor is within a certain range. As dust accumulates, when local blockage occurs on the filter plate 2, the airflow in that part decreases, the airflow impact force on the adsorption plate 73 decreases, the deformation of the elastic part 71 also decreases, and the magnetic field strength monitored by the Hall sensor at that location also decreases accordingly. By detecting changes in magnetic field strength through the Hall sensor, the degree of dust accumulation on the filter plate 2 can be determined. When the dust accumulates to a certain level, that is, when the change in magnetic field strength reaches a preset threshold, the Hall sensor will promptly send a signal to the control system to activate the cleaning and collection component for cleaning.

[0036] Through the preliminary filtration of the filter screen 2 and the electrostatic adsorption of the adsorption plate 73, dust particles, including tiny impurities, in the air can be effectively removed, further improving the cleanliness of the air entering the air conditioning system and providing a cleaner indoor air environment, which is beneficial to the health of users. By using the combination of Hall sensor and magnetic coating, the degree of dust accumulation on the filter screen 2 can be accurately detected, and local blockage can be detected in time. This detection method enables the system to start the cleaning and collection components in time according to the actual situation, avoiding the impact of excessive dust accumulation on the air intake quality and normal operation of the air conditioning system, and ensuring the efficient operation of the air conditioning system.

[0037] The adsorption plate 73, working in conjunction with the elastic part 71, magnetic coating, and Hall sensor, provides feedback on the clogging status of the filter screen 2. When the filter screen 2 is partially clogged, the airflow in that area decreases, correspondingly changing the airflow impact force on the adsorption plate 73. This causes a corresponding change in the deformation of the elastic part 71, and the magnetic field strength monitored by the Hall sensor also changes, thus providing feedback on the clogging status and informing the system whether to activate the cleaning and collection components. Furthermore, the adsorption plate 73 utilizes electrostatic adsorption to effectively adsorb tiny dust particles in the air. Even small impurities that the filter screen 2 fails to intercept can be captured by the adsorption plate 73. The long strip design of the adsorption plate 73, with several plates evenly distributed within the duct 1, increases the contact area with the air, allowing for more comprehensive dust adsorption of the passing air. This further improves the cleanliness of the air entering the air conditioning system, reduces the impact of dust on internal components, and extends the service life of the air conditioning system.

[0038] Example 3, refer to Figures 3-12The cleaning and collection components include an air guide box 3, a filter bag 4, a magnetic blocking plate 6, and a ash discharge port 9 on the bottom wall of the pipe 1. A mounting groove 91 is provided in the bottom wall of the pipe 1 corresponding to the ash discharge port 9. An electromagnet 63 is fixedly installed in the mounting groove 91 near the filter screen plate 2, and a spring 62 is fixedly connected inside the mounting groove 91 away from the filter screen plate 2. The end of the spring 62 is fixedly connected to one side of the magnetic blocking plate 6. Several pressure rods 61 are fixedly connected to the side of the magnetic blocking plate 6 facing the filter screen plate 2. Through holes matching the pressure rods 61 are provided inside the electromagnet 63 and the bottom wall of the pipe 1. The end of the through hole in the bottom wall of the pipe 1 penetrates the side wall of the mounting groove 91 and the movable groove 76. The air guide box 3 is slidably disposed inside the pipe 1. The interior of the air guide box 3 is hollow. Limiting sliders 30 are fixedly connected to both the upper and lower ends of the air guide box 3. A mounting groove 91 is provided on the inner wall of the pipe 1. The air guide box 3 has a groove that matches the limit slider 30, allowing it to slide stably within the pipe 1. The end of the groove on the lower side penetrates the bottom wall of the pipe 1. A motor 2 33 is fixedly installed on the inner top wall of the air guide box 3. The output end of the motor 2 33 penetrates the top wall of the air guide box 3, and a gear 1 331 is fixedly connected to its end. A rack 332 that meshes with the gear 1 331 is fixedly installed on the top side of the filter screen plate 2 facing the air guide box 3. An air pump 32 is installed on the side wall of the air guide box 3 away from the filter screen plate 2. The air delivery end of the air pump 32 is located inside the air guide box 3. When the motor 2 33 starts, it drives the gear 1 331 to rotate. Through meshing with the rack 332, the air guide box 3 moves along the groove in the pipe 1. By controlling the forward and reverse rotation of the motor 2 33, the air guide box 3 can move back and forth, ensuring thorough cleaning of the entire filter screen plate 2 area.

[0039] Furthermore, a magnetic frame 41 is fixedly connected to the upper side of the filter bag 4. The filter bag 4 is magnetically attracted to the bottom wall of the pipe 1 through the magnetic frame 41. The magnetic installation method allows the filter bag 4 to be easily removed when cleaning is required and reinstalled after cleaning. This design is convenient for maintenance and ensures the stability and sealing of the filter bag 4 during use. A positioning block 42 is fixedly installed on the bottom wall of the pipe 1 to limit the magnetic frame 41. The filter bag 4 can completely cover the chute and the dust discharge port 9, ensuring that dust can fall into the filter bag 4. An air guide trough 31 is opened through the air guide box 3 facing the filter screen plate 2. The design of the air guide trough 31 allows the airflow to be concentrated and blown towards the part that needs cleaning. The air guide 31, with its end abutting against the side wall of the filter screen 2, enhances the impact force and cleaning effect of the airflow. When the air guide box 3 moves, the air guide 31 can clean the surface of the filter screen 2. At the same time, when the air guide box 3 moves, the air pump 32 starts, and the generated airflow blows through the air guide 31 towards the filter screen 2 and the adsorption plate 73. The powerful airflow can blow off the dust adsorbed on the filter screen 2 and the adsorption plate 73, thus cleaning the dust. After the air pump 32 blows off the dust, the dust will fall into the cloth bag 4, thus collecting the dust. This can prevent the dust from flying again in the pipe 1, keep the pipe 1 clean, and also facilitate the subsequent centralized treatment of the dust.

[0040] It should be noted that the top of the slide groove near the filter screen plate 2 and the top of the movable groove 76 are both chamfered to ensure that the cleaned dust can enter the bag 4 along the chamfered corner. The end section of the pressure rod 61 facing the filter screen plate 2 is arc-shaped to ensure effective contact with the connecting plate 7. The sensing rod 8, motor 1 5, air pump 32, electromagnet 63 and motor 2 33 are electrically connected. When the electromagnet 63 is energized, the opposite surface of it and the magnetic blocking plate 6 are magnetically set with the same polarity. When the electromagnet 63 is not energized, the magnetic blocking plate 6 completely blocks the ash discharge port 9, and the end of the pressure rod 61 abuts against the side wall of the connecting plate 7. At this time, the connecting plate 7 is limited by the pressure rod 61, and at the same time, it prevents the airflow of the air conditioner from entering the bag 4 and avoids the dust from being blown away.

[0041] When the electromagnet 63 is energized, the ash discharge port 9 is open, and the baffle 54 completely blocks the pipe 1. At this time, it is in the ash cleaning state. Under the airflow of the air pump 32, the dust will be blown off and enter the filter bag 4 through the ash discharge port 9 after being blocked by the baffle 54. The dust is intercepted by the filter bag 4, and the airflow passes through the mesh of the filter bag 4. When the sensing rod 8 detects that the dust on the filter plate 2 and the adsorption plate 73 has accumulated to a certain extent, it will send a signal to the control system. The control system will sequentially control the motor 1 5 to close the baffle 54 (to prevent dust from entering the air conditioner or the room during cleaning), and control the electromagnet 63 to open the ash discharge port 9. Then, the motor 2 33 will be started to move the air guide box 3 to the designated position. Then, the air pump 32 will be started to clean the dust. This automatic control improves the working efficiency and accuracy of cleaning and collecting components, reduces manual intervention, and flexibly opens and closes the ash discharge port 9 according to the ash cleaning needs. This ensures the airtightness of the air conditioner during normal operation and allows the dust to be discharged smoothly during ash cleaning.

[0042] Specifically, when the ash discharge port 9 is opened, the pressure rod 61 no longer contacts the connecting plate 7. The entire assembly consisting of the connecting plate 7, the adsorption plate 73, and the elastic part 71 is in a relatively free movement state. When the air guide box 3 approaches the corresponding adsorption plate 73, the powerful airflow generated by the air pump 32 is ejected from the air guide slot 31. Due to the high air pressure, this air force acts on the adsorption plate 73, pushing the adsorption plate 73, the connecting plate 7, and the elastic part 71 to move backward as a whole. During this process, the second spring 74 is stretched, and its elastic force gradually increases. It is only because the air force overcomes the elastic force of the second spring 74 that the entire assembly moves. When the air guide box 3 moves away, the force of the air force generated by the air pump 32 on the adsorption plate 73 disappears. At this time, the spring 74, which had been stretched and stored elastic potential energy, releases its elastic force, pulling the connecting plate 7 to reset as a whole. As the connecting plate 7 resets, the ball 72 connected to the upper end of the elastic part 71 strikes the filter screen 2. This is because during the reset process, the ball 72 moves quickly towards the filter screen 2 along with the movement of the connecting plate 7, thus producing a striking action. The powerful airflow generated by the air pump 32 is ejected from the air guide groove 31 and acts directly on the adsorption plate 73 and the filter screen 2. For the adsorption plate 73, the air force can blow off the dust adsorbed on its surface, using the impact force of the airflow to separate the dust from the adsorption plate 73. For the filter screen 2, the air force can blow away the dust attached to its mesh and surface, clearing the mesh and ensuring normal airflow.

[0043] The sphere 72 vibrates when it strikes the filter screen 2. This vibration loosens the dust adhering to the filter screen 2, especially dust that is tightly attached to the inside or surface of the mesh. Under the action of vibration, it is easier to fall off. Combined with wind-powered cleaning, the knocking cleaning can handle stubborn dust that is difficult to remove by wind, further improving the thoroughness of cleaning. Wind-powered cleaning and knocking cleaning work together to form a more efficient cleaning method. Wind-powered cleaning is mainly for surface and loose dust, while knocking cleaning is for stubborn dust. The two work together to clean the filter screen 2 and the adsorption plate 73 in an all-round and deep way, which greatly improves the cleaning effect of the entire cleaning and collection component and ensures the cleanliness of the air intake of the air conditioner.

[0044] When the ash discharge port 9 is opened and the pressure rod 61 no longer restricts the connecting plate 7, the adsorption plate 73 and other components can move under the action of wind and realize the subsequent knocking cleaning action. At the same time, the opening of the ash discharge port 9 also provides a discharge channel for the dust that falls during the cleaning process, ensuring that the dust can smoothly enter the filter bag 4 for collection. The movement of the air guide box 3 is closely related to the movement of the adsorption plate 73 and other components. When the air guide box 3 is close to the adsorption plate 73, it provides wind to drive the component to move. When it moves away, it triggers the second spring 74 to reset the component and realize knocking cleaning. This coordinated action makes the cleaning process proceed in an orderly manner, improving the working efficiency and cleaning effect of the entire system.

[0045] In this embodiment, when the sensing rod 8 detects that dust has accumulated to a certain extent on the filter plate 2 and the adsorption plate 73, or when the filter plate 2 is blocked, it will send a signal to the control system. After receiving the signal, the control system first controls the motor 5 to start, so that the baffle 54 completely blocks the pipe 1 to prevent dust from entering the air conditioner or the room during the dust removal process. At the same time, it controls the electromagnet 63 to be energized. Since the electromagnet 63 and the magnetic blocking plate 6 have the same magnetic poles on opposite sides and repel each other, the electromagnet 63 overcomes the elastic force of the spring 62 and pushes the magnetic blocking plate 6 open, so that the dust discharge port 9 is opened to prepare for the dust discharge.

[0046] Next, motor 2 33 is started. The output end of motor 2 33 drives gear 1 331 to rotate. Gear 1 331 meshes with rack 332. According to the gear-rack transmission principle, the air guide box 3 moves along the slide groove in the pipe 1. By controlling the forward and reverse rotation of motor 2 33, the air guide box 3 can move back and forth in the pipe 1, so that it can cover the entire filter screen plate 2 area. When the air guide box 3 approaches the corresponding adsorption plate 73, the air pump 32 is started. The powerful airflow generated by the air pump 32 is sprayed out from the air guide groove 31. The air pressure acts on the adsorption plate 73, pushing the adsorption plate 73, connecting plate 7 and elastic part 71 to move backward as a whole. Spring 2 74 is stretched. When the air guide box 3 moves away, the air pump 32 stops working, spring 2 74 releases its elasticity, pulls the connecting plate 7 to reset as a whole, and the ball 72 connected to the upper end of the elastic part 71 knocks on the filter screen plate 2, loosening the dust attached to the filter screen plate 2.

[0047] Under the airflow of the air pump 32, the dust adsorbed on the filter screen 2 and the adsorption plate 73 is blown off. Since the baffle 54 has blocked the pipe 1, the dust enters the bag 4 through the ash discharge port 9 after being blocked by the baffle 54. The magnetic frame 41 on the upper side of the bag 4 is magnetically adsorbed on the bottom wall of the pipe 1, and the bag 4 can completely cover the chute and the ash discharge port 9. The dust is intercepted by the bag 4, and the airflow passes through the mesh of the bag 4, thus achieving effective collection of dust.

[0048] After the dust removal work is completed, the control system controls the electromagnet 63 to de-energize, and the elastic force of the spring 62 causes the magnetic blocking plate 6 to completely block the ash discharge port 9. The end of the pressure rod 61 abuts against the side wall of the connecting plate 7 again, limiting the connecting plate 7. At the same time, the control motor 5 opens the baffle 54, restoring the normal air intake state of the pipe 1, and waiting for the next dust removal command.

[0049] By combining wind-powered cleaning and tapping cleaning, the filter screen 2 and adsorption plate 73 are cleaned comprehensively and deeply. Wind-powered cleaning quickly blows away surface and loose dust, while tapping cleaning can handle stubborn dust, greatly improving the cleaning effect, ensuring the cleanliness of the air intake of the air conditioner, and helping to improve the working efficiency and cooling and heating effect of the air conditioner. The entire cleaning and collection process is monitored by the sensor rod 8 to detect the dust accumulation, and the control system automatically controls the action of each component, reducing manual intervention and improving the accuracy and timeliness of the work. This avoids problems such as incomplete cleaning or equipment damage caused by untimely or inaccurate manual operation. During the cleaning process, the baffle 54 blocks the pipe 1 to prevent dust from entering the air conditioner or the room. The dust discharge port 9 is blocked by the magnetic blocking plate 6 when not cleaning to prevent dust leakage. The cloth bag 4 effectively collects dust, preventing dust from flying again in the pipe 1, preventing secondary pollution, and protecting the indoor environment and the components of the air conditioning system.

[0050] It should be noted that the baffle 54, through its connection with components such as the incomplete gear 53, enables control over the opening of the pipe 1. Simultaneously, during the dust removal process, when the air pump 32 starts and blows off the dust adsorbed on the filter plate 2 and the adsorption plate 73, the baffle 54 completely seals off the pipe 1, acting as a wall. This effectively prevents dust from entering the air conditioner or indoor space under the influence of airflow. Without the baffle 54, the blown-off dust might re-enter the air conditioning system with the airflow, contaminating internal components, or directly enter the room, affecting indoor air quality and posing a threat to user health. The presence of the baffle 54 ensures... During the dust removal process, dust can be collected in the pipe 1 and enter the filter bag 4 through the dust discharge port 9, preventing dust from overflowing. The baffle 54 can also guide the dust to move towards the dust discharge port 9, making it easier for the dust to enter the filter bag 4 for collection. After the dust is blown off by the air pump 32, due to the obstruction of the baffle 54, the dust cannot spread in other directions and can only move downward in the pipe 1, eventually entering the filter bag 4 through the dust discharge port 9. This can improve the efficiency of dust collection, ensure that the dust can be effectively collected, reduce the possibility of dust residue in the pipe 1, keep the pipe 1 clean, and is conducive to the long-term stable operation of the air conditioning system.

[0051] It should be noted that the specific models and specifications of the motor and air pump need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.
