Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning accessories, and more specifically, to an automatic cleaning device for an air-conditioning unit filter. Background Art

[0002] The air-conditioning unit filter is a crucial component in the air-conditioning system. It is mainly used to remove dust, particulate matter, and other pollutants in the air entering the system to ensure air quality and protect the internal components of the air-conditioning equipment from pollution and damage. The automatic cleaning device for the air-conditioning unit filter is a device used to improve the efficiency of the air-conditioning system and reduce maintenance costs. This device is usually installed at the air inlet of the air-conditioning system, and its main function is to automatically remove the dust and other particulate matter accumulated on the filter, ensure smooth air circulation, and maintain the efficient operation of the air-conditioning system.

[0003] Common filter cleaning devices usually have rotating brushes or scrapers inside. When the pressure difference reaches a preset value, the control system will start the motor to drive the brushes or scrapers to move along the surface of the filter screen to remove the accumulated dust and particulate matter, which can effectively remove most of the dust on the filter screen. There are also backwashing automatic cleaning filters that flush the filter with reverse water flow or other media (such as air) to remove the pollutants attached to the filter screen. It usually includes a control valve that can switch between forward flow and reverse flow to achieve the purpose of cleaning the filter unit, and various types of cleaning devices are configured according to the type of air-conditioning system.

[0004] In the actual use of the prior art, since the degree of blockage of the filter varies in different seasons and environments when using the air conditioner, a single cleaning method may not be able to handle various blockage situations, and it is easy to have the situation of incomplete cleaning when the filter is severely blocked, and at the same time, there is also the situation of over-cleaning when the filter is slightly blocked. Therefore, in view of the above technical problems, it is necessary to provide an automatic cleaning device for an air-conditioning unit filter. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic cleaning device for an air-conditioning unit filter to solve the above problems.

[0006] To achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows: An automatic cleaning device for an air conditioner unit filter, comprising an outer frame, a moving component and a cleaning component. The outer frame has a filter screen fixedly connected to its inner cavity. At the top of the inner cavity of the outer frame, an anemometer is fixedly connected, and at the top of the inner cavity of the outer frame, a controller is fixedly connected, and the side of the controller is fixedly connected to the anemometer. There are two fixed frames symmetrically and fixedly connected to the inner cavity of the outer frame, and the filter screen is located in the middle of the two fixed frames. A first screw is rotatably connected to the inner cavity of the fixed frame. A first moving block is threadedly connected to the outer surface of the first screw. A moving frame is fixedly connected to one side of the first moving block. A second screw is rotatably connected to the inner cavity of the moving frame. A second moving block is threadedly connected to the outer surface of the second screw. A dust suction hood is fixedly connected to one side of the second moving block. There are two dust suction hoods, which are symmetrically arranged on both sides of the filter screen. An inclined blowing nozzle and a flat blowing nozzle are fixedly connected to the inner cavities of the two dust suction hoods. The inclined blowing nozzle is located in the inner cavity of the dust suction hood outside the filter screen, and the flat blowing nozzle is located in the inner cavity of the dust suction hood inside the filter screen. The flat blowing nozzle is located below the inclined blowing nozzle. One end of the flat blowing nozzle away from the air inlet hose communicates with a connecting pipe. On both sides of the inner cavity of the connecting pipe, two electromagnets are symmetrically and fixedly connected. A deep cleaning component corresponding to the electromagnets is installed in the inner cavity of the connecting pipe.

[0007] As a further improvement of the present invention, the detection probe of the anemometer is located inside the filter screen, and the anemometer is electrically connected to the controller.

[0008] As a further improvement of the present invention, a first motor is fixedly connected to the top of the inner cavity of the fixed frame, and the output shaft end of the first motor is fixedly connected to the upper end of the first screw.

[0009] As a further improvement of the present invention, a second motor is fixedly connected to one side of the inner cavity of the moving frame, and the output shaft end of the second motor is fixedly connected to the other end of the first screw. The controller is electrically connected to the first motor and the second motor respectively.

[0010] As a further improvement of the present invention, the first moving block moves in the inner cavity of the fixed frame, and the second moving block moves in the inner cavity of the moving frame.

[0011] As a further improvement of the present invention, a first three-way pipe is fixedly connected to the lower end of the inner cavity of the outer frame, and a second three-way pipe is fixedly connected to the position above the first three-way pipe in the inner cavity of the outer frame. The other two ends of the first three-way pipe are located in the inner cavity of the outer frame and are connected to two air inlet hoses. An air inlet pump is installed at one end of the first three-way pipe away from the air inlet hoses.

[0012] As a further improvement of the present invention, the other ends of the two air inlet hoses are respectively connected and communicated with the flat blowing nozzle and the inclined blowing nozzle. The other two ends of the second three-way pipe are located in the inner cavity of the outer frame and are connected to two dust extraction hoses. A dust extraction pump is installed at one end of the second three-way pipe away from the dust extraction hoses.

[0013] As a further improvement of the present invention, the other ends of the two dust extraction hoses are respectively connected and communicated with the inclined side surfaces below the two dust suction covers, and the controller is electrically connected to the air inlet pump and the air extraction pump respectively.

[0014] As a further improvement of the present invention, the deep cleaning component includes a deep cleaning ball made of silica gel material. A horn-shaped through hole that gradually increases from the inside to the outside is provided in the inner cavity of the deep cleaning ball. A plurality of fiber bundles are uniformly fixedly connected to the outer surface of the deep cleaning ball close to the filter screen side. Two magnetic blocks are symmetrically and fixedly connected to the outer surface of the deep cleaning ball, and the magnetic blocks are magnetically connected to the electromagnets.

[0015] As a further improvement of the present invention, a ring groove is provided in the middle of the inner cavity of the horn-shaped through hole of the deep cleaning ball, and a non-woven fabric is fixedly connected to the opening of the groove. A solid disinfectant is filled in the ring groove of the deep cleaning ball.

[0016] Compared with the prior art, the advantages of the present invention are as follows: (1) In this solution, air enters from the outside of the outer frame and passes through the filter screen to capture dust and other particulate matters in the air. The air velocity through the filter screen is monitored in real time by an anemometer. The anemometer transmits the monitored air velocity data through the filter screen to the controller. The controller is set with a preset air velocity value. When the air velocity drops below this value, the controller determines that the filter screen is blocked. At this time, the controller automatically activates the daily cleaning mode. When the filter screen has been used for a long time and the anemometer monitors that the air velocity through the filter screen after daily cleaning still cannot return to the normal preset value, deep cleaning is activated at this time, the state of the filter screen is automatically detected and corresponding cleaning operations are performed, meeting various cleaning requirements, reducing the need for manual inspection and manual cleaning, and ensuring that the filter screen can maintain a high cleanliness at any time; (2) In this solution, the controller controls the start of the first motor to drive the first moving block to move vertically, and then starts the second motor to drive the second moving block to move horizontally, thereby realizing the omnidirectional movement of the dust suction hood, ensuring that every corner of the filter screen surface can be thoroughly cleaned. When the dust suction hood moves vertically from top to bottom, the air inlet pump is started to send high-pressure air into the inclined blowing nozzle and the flat blowing nozzle respectively. The flat blowing nozzle blows air from the inside of the filter screen to the outside, and through the gradually increasing arc-shaped round holes in the deep cleaning ball, the speed of the gas flow is increased to help blow away the dust and cotton wool on the filter screen more loosely to the outside. Then, the inclined blowing nozzle blows air obliquely downward from the outside of the filter screen to the inside at the normal air velocity, blowing the dust and cotton wool blown out by the flat blowing nozzle downward. Then, the air extraction pump is started to suck and discharge the blown dust and cotton wool through the cooperation of the dust extraction hose and the dust suction hood. By accelerating the wind force and blowing from multiple angles to achieve efficient blowing and sweeping, the cleaning efficiency is further improved, and the synchronous dust extraction avoids the re-deposition or diffusion of dust and maintains the cleaning effect; (3) In this solution, the electromagnet is controlled to release the deep cleaning ball. After the deep cleaning ball loses the adsorption effect of the electromagnet, it moves outward under the action of the high-pressure air velocity in the flat blowing nozzle and impacts the filter screen, generating resonance, thereby shaking off the dust and adhered cotton wool that are difficult to clean on the filter screen. When impacting the filter screen, multiple fiber bundles on the outer surface penetrate into the holes of the filter screen, pushing out the stubborn and non-detachable dust and impurities in the holes of the filter screen. The inner cavity of the deep cleaning ball is filled with solid disinfectant and floats or volatilizes outward through the non-woven fabric. Along with the wind flow, the solid disinfectant floats or volatilizes to the filter screen for automatic disinfection. Through mechanical vibration and multi-point contact, the areas that are difficult to reach are further cleaned, and the automatic disinfection function is combined, not only improving the cleaning effect of the air conditioner filter screen, but also significantly improving the indoor air quality.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figure 1-3 , an automatic cleaning device for an air conditioner unit filter, including an outer frame 1, a moving component 2 and a cleaning component 3. A filter screen 101 is fixedly connected to the inner cavity of the outer frame 1, an anemometer 102 is fixedly connected to the top of the inner cavity of the outer frame 1, a controller 103 is fixedly connected to the top of the inner cavity of the outer frame 1, and the side surface of the controller 103 is fixedly connected to the anemometer 102.

[0021] Specifically, the detection probe of the anemometer 102 is located inside the filter screen 101. The anemometer 102 is electrically connected to the controller 103. The controller 103 is respectively electrically connected to the first motor 203 and the second motor 209. The controller 103 is respectively electrically connected to the air inlet pump 301 and the air extraction pump 302.

[0022] Further, the outer frame 1 is the housing of the entire air conditioner unit, providing structural support and protection. During use, air enters from the outside of the outer frame 1, and the filter screen 101 captures dust and other particulate matters in the air. The anemometer 102 monitors the air flow rate passing through the filter screen 101 in real time. The detection probe of the anemometer 102 is located inside the filter screen 101 and in the middle position, which can detect the wind speed more accurately.

[0023] The anemometer 102 transmits the wind speed data of the air passing through the filter screen 101 to the controller 103. The controller 103 is set with a preset wind speed value. When the wind speed drops below this value, the controller 103 determines that the filter screen is blocked, and at this time, the controller 103 automatically activates the daily cleaning mode.

[0024] After the filter screen 101 has been used for a long time, when the anemometer 102 monitors that the air flow rate passing through the filter screen 101 still cannot return to the normal preset value after daily cleaning, it means that the filter screen 101 needs to be deeply cleaned at this time. The cleaning mode is automatically adjusted according to the situation of the filter screen 101 to meet various cleaning requirements. The controller 103 controls the operations of the first motor 203, the second motor 209, the air inlet pump 301, the air extraction pump 302, and the electromagnet 308 in the system.

[0025] Embodiment 2: Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 A filter automatic cleaning device for an air conditioner unit, including two fixed frames 201 symmetrically and fixedly connected inside the inner cavity of the outer frame 1, and the filter screen 101 is located in the middle position between the two fixed frames 201. A first screw rod 202 is rotatably connected inside the fixed frame 201. A first moving block 204 is threadedly connected to the outer surface of the first screw rod 202. A moving frame 205 is fixedly connected to one side of the first moving block 204. A second screw rod 206 is rotatably connected inside the moving frame 205. A second moving block 207 is threadedly connected to the outer surface of the second screw rod 206. A dust suction hood 208 is fixedly connected to one side of the second moving block 207. The number of dust suction hoods 208 is two and they are symmetrically arranged on both sides of the filter screen 101.

[0026] Specifically, a first motor 203 is fixedly connected to the top of the inner cavity of the fixed frame 201. The output shaft end of the first motor 203 is fixedly connected to the upper end of the first screw rod 202. A second motor 209 is fixedly connected to one side of the inner cavity of the moving frame 205. The output shaft end of the second motor 209 is fixedly connected to the other end of the first screw rod 202. The first moving block 204 moves within the inner cavity of the fixed frame 201, and the second moving block 207 moves within the inner cavity of the moving frame 205.

[0027] Further, when the daily mode cleaning mode is turned on, the controller 103 controls the start of the first motor 203 to drive the first screw rod 202 to rotate, driving the first moving block 204 to move in the vertical direction. Then, the second motor 209 is started to drive the second screw rod 206 to rotate, driving the second moving block 207 to move in the horizontal direction, thereby realizing the omnidirectional movement of the dust suction hood 208 to clean different positions on the filter screen 101.

[0028] The dust suction hood 208 moves horizontally to cover different areas of the filter screen 101. Then, the dust suction hood 208 moves from top to bottom to ensure that each position can be effectively cleaned. The movement path of the dust suction hood 208 is to first perform a horizontal traverse and then a vertical traverse in the vertical direction, ensuring that every corner of the filter screen surface can be thoroughly cleaned.

[0029] There are two dust suction hoods 208 symmetrically installed on both sides of the filter screen 101. The movement paths and positions are the same, and both sides of the filter screen 101 can be cleaned simultaneously, which is more efficient than traditional single-sided cleaning.

[0030] Embodiment 3: Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9, An automatic cleaning device for an air conditioner unit filter, which includes a tee pipe 3011 fixedly connected to the inner cavity at the lower end of the outer frame 1. Inside the outer frame 1 above the tee pipe 3011, a tee pipe 3021 is fixedly connected. The other two ends of the tee pipe 3011 are located inside the outer frame 1 and are connected to two air inlet hoses 303. The other two ends of the tee pipe 3021 are located inside the outer frame 1 and are connected to two dust extraction hoses 304. The other ends of the two air inlet hoses 303 are respectively connected to an inclined blowing nozzle 305 and a flat blowing nozzle 306. The inclined blowing nozzle 305 is located inside the dust suction cover 208 outside the filter screen 101 and is fixedly connected to the dust suction cover 208. The flat blowing nozzle 306 is located inside the dust suction cover 208 inside the filter screen 101 and is fixedly connected to the dust suction cover 208. The other ends of the two dust extraction hoses 304 are respectively connected to the inclined sides below the two dust suction covers 208. One end of the flat blowing nozzle 306 away from the air inlet hose 303 is connected to a connecting pipe 307. On both sides of the inner cavity of the connecting pipe 307, electromagnets 308 are symmetrically fixedly connected. Inside the inner cavity of the connecting pipe 307, two magnetic blocks 310 are symmetrically slidably connected. Between the two magnetic blocks 310, a deep cleaning ball 309 is fixedly connected. One side of the magnetic block 310 is fixedly connected to a spring 311.

[0031] Specifically, an air inlet pump 301 is installed at one end of the tee pipe 3011 away from the air inlet hose 303, and an air extraction pump 302 is installed at one end of the tee pipe 3021 away from the dust extraction hose 304. The flat blowing nozzle 306 is located below the inclined blowing nozzle 305. The deep cleaning ball 309 is an elastic ball made of silica gel. The other end of the spring 311 is fixedly connected to the inner side wall of the connecting pipe 307. In the annular groove of the deep cleaning ball 309, a solid disinfectant 3092 is filled. On the outer surface of one side of the deep cleaning ball 309 close to the filter screen 101, a plurality of fiber bundles 3091 are evenly fixedly connected. The fiber bundles 3091 are made of elastic materials such as nylon fiber, polyester fiber, natural fiber, etc., which are soft but can also penetrate into the holes and gaps of the filter screen 101, effectively removing accumulated dust, fibers and other particulate matters, and will not scratch or damage the surface of the filter screen 101, ensuring that the filter screen 101 can still maintain its original filtering performance after multiple cleanings.

[0032] Furthermore, first, start the air inlet pump 301. Through the cooperation of the tee pipe 3011 and the air inlet hose 303, high-pressure air is respectively sent into the inclined blowing nozzle 305 and the flat blowing nozzle 306 inside the dust suction covers 208 symmetrically installed on both sides of the filter screen 101. The air inlet hose 303 is a flexible hose, which can meet the requirement of the random movement of the dust suction cover 208.

[0033] The horizontal blowing nozzle 306 blows air from the inside of the filter screen 101 to the outside, and passes through the gradually increasing arc-shaped round holes in the deep cleaning ball 309 to increase the speed when the gas flows, helping to blow away the dust and cotton wool on the filter screen 101 more loosely to the outside. Then, through the inclined blowing nozzle 305, it blows air obliquely downward from the outside of the filter screen 101 to the inside at a normal wind speed, blowing down the dust and cotton wool blown out by the horizontal blowing nozzle 306. The accelerated air blown out by the horizontal blowing nozzle 306 can blow away the dust and cotton wool adhering to the filter screen 101 to the outside, and cooperate with the normal wind blown out by the inclined blowing nozzle 305 to blow down the dust and cotton wool, improving the cleaning effect of the filter screen 101. The horizontal blowing nozzle 306 is located below the inclined blowing nozzle 305. During cleaning, first, the horizontal blowing nozzle 306 blows away the dust and cotton wool on the filter screen 101, and then the inclined blowing nozzle 305 blows down the dust and cotton wool.

[0034] Then start the exhaust pump 302 to suck away and discharge the blown-down dust and cotton wool through the cooperation of the dust suction hose 304 and the dust suction hood 208 to achieve daily cleaning. Control the electromagnet 308 to release the deep cleaning ball 309 through the controller 103. At this time, after the deep cleaning ball 309 loses the adsorption effect of the electromagnet 308, it moves outward under the action of the high-pressure wind speed in the horizontal blowing nozzle 306 and compresses the spring 311, driving the deep cleaning ball 309 to impact the filter screen 101, generating resonance, thereby shaking off the dust and adhered cotton wool that are difficult to clean on the filter screen 101.

[0035] During daily cleaning, the electromagnet 308 turns on the adsorption magnet 310 to fix the position of the deep cleaning ball 309 and prevent it from moving randomly. During deep cleaning, the electromagnet will release the magnet 310, and only then will the deep cleaning ball 309 move along with the high-pressure wind speed.

[0036] The deep cleaning ball 309 is an elastic ball made of silica gel material, with a certain elasticity, which is safer when contacting the filter screen 101 and avoids abrasion to the filter screen 101. When the deep cleaning ball 309 impacts the filter screen 101, through multiple fiber bundles 3091 on the outer surface, it penetrates into the holes of the filter screen 101 and pushes out the stubborn dust and impurities that are not easy to fall off in the holes of the filter screen 101. The spring 311 provides elastic support and helps the deep cleaning ball 309 return to its original position, enabling the deep cleaning ball 309 to better contact the surface of the filter screen 101. The inner cavity of the deep cleaning ball 309 is filled with a solid disinfectant 3092 and floats or volatilizes outward through the non-woven fabric 3093. The gaps in the non-woven fabric 3093 can control the amount of its floating or volatilization. With the wind flow, the solid disinfectant 3092 floats or volatilizes to the filter screen 101 for automatic disinfection. When the non-woven fabric 3093 is installed, its area is larger than the opening of the inner cavity of the deep cleaning ball 309. At this time, the high-pressure wind speed will drive the non-woven fabric 3093 to vibrate during flow, so that the solid disinfectant 3092 can better float and volatilize outward. After the cleaning is completed, the moving component 2 returns all components to the initial position to prepare for the next cycle.

[0037] The solid disinfectant 3092 can be a powdered disinfectant. Common materials include chlorophenols and quaternary ammonium salts. It has certain antibacterial and antiviral properties and can provide a pleasant aroma. It can also be a slow-release disinfection gel. The active ingredients in the gel gradually evaporate into the air to achieve continuous disinfection. These types do not need to be replaced frequently and can maintain an effective disinfection concentration for a long time.

[0038] Working principle: During the use of the device, air enters from the outside of the outer frame 1 and passes through the filter 101 to capture dust and other particulate matters in the air. The anemometer 102 monitors the air flow rate passing through the filter 101 in real time. The anemometer 102 transmits the monitored wind speed data of the air passing through the filter 101 to the controller 103. When the controller 103 determines that the filter is blocked, the controller 103 automatically activates the daily cleaning mode. The controller 103 controls the start of the first motor 203 to drive the first screw 202 to rotate, driving the first moving block 204 to move vertically. Then, the second motor 209 is started to drive the second screw 206 to rotate, driving the second moving block 207 to move horizontally, thereby realizing the omnidirectional movement of the dust suction hood 208. When the dust suction hood 208 moves vertically from top to bottom, the air inlet pump 301 is started to send high-pressure air into the inclined blowing nozzle 305 and the flat blowing nozzle 306 respectively. The flat blowing nozzle 306 blows air from the inside of the filter 101 to the outside, blowing away the dust and cotton wool on the filter 101. Then, through the inclined blowing nozzle 305, air is blown obliquely downward from the outside of the filter 101 to the inside, blowing the dust and cotton wool blown out by the flat blowing nozzle 306 downward. The accelerating air blown out by the flat blowing nozzle 306 can blow away the dust and cotton wool attached to the filter 101, and cooperate with the normal air blown out by the inclined blowing nozzle 305 to blow the dust and cotton wool downward. Then, the exhaust pump 302 is started to suck and discharge the blown dust and cotton wool through the cooperation of the dust suction hose 304 and the dust suction hood 208. When the filter 101 has been used for a long time and the anemometer 102 monitors that the air flow rate passing through the filter 101 still cannot return to the normal preset value after daily cleaning, it means that the filter 101 needs to be deeply cleaned at this time. The controller 103 controls the electromagnet 308 to release the deep cleaning ball 309. At this time, after the deep cleaning ball 309 loses the adsorption of the electromagnet 308, it moves outward under the action of the high-pressure wind speed in the flat blowing nozzle 306 and compresses the spring 311, driving the deep cleaning ball 309 to impact the filter 101, thereby shaking off the dust and adhered cotton wool that are difficult to clean on the filter 101. When the deep cleaning ball 309 impacts the filter 101, multiple fiber bundles 3091 on the outer surface penetrate into the holes of the filter 101, pushing out the stubborn dust and impurities that are not easy to fall off. The inner cavity of the deep cleaning ball 309 is filled with the solid disinfectant 3092 and is sprinkled or volatilized outward through the non-woven fabric 3093. With the wind flow, the solid disinfectant 3092 is sprinkled or volatilized onto the filter 101 for automatic disinfection.
