Description

Technical Field

[0001] This invention relates to the field of air conditioning, and more particularly to a plate heat exchanger cleaning device. Background Technology

[0002] The cleaning and straightening of the evaporator fins in existing air conditioner outdoor units are all done manually. Since only one side of the fins is exposed, there are blind spots when people clean and straighten the fins from one side, and the cleaning and straightening are not thorough.

[0003] The current method involves disassembling the outdoor unit of the air conditioner, spraying air conditioner cleaner on the evaporator fins, and then rinsing it with a water gun. Since the outdoor unit of the air conditioner usually only has one side of fins exposed, with a fan installed behind it, and the other four sides are the air conditioner casing, when people spray cleaner or rinse the evaporator with water, they can only clean the evaporator from the exposed side. The evaporator has dense fins and is welded with copper pipes, so there are dead corners when cleaning the evaporator from one side, resulting in poor cleaning effect.

[0004] Current methods typically utilize fin straightening combs or brushes specifically designed for air conditioner fins to straighten the fallen fins. Fin straightening combs consist of multiple sets of plastic combs on a ring-shaped plastic block to accommodate different fin spacings. Due to the softness of the plastic, repeated combing is required to straighten the fins, and even after straightening, the fins may still have slight curvature. Fin straightening brushes consist of a row of stainless steel needles. The density of the needles is adjusted by rubber rings fitted onto the brush, which is then inserted between the fins for straightening. However, because the stainless steel needles are easily deformed, repeated combing is required to straighten the fins, and even after straightening, the fins may still have slight curvature. While both fin straightening combs and brushes can achieve some straightening effect, the results are not as expected. Furthermore, their adaptation to different fin spacings is limited, and they cannot effectively conform to the fins for straightening. Additionally, the small size of the fin straightening combs or brushes makes them inefficient when used to straighten large areas of fallen fins on evaporators. Summary of the Invention

The spraying system can be raised and lowered to fit the evaporator to be treated for spraying the cleaning agent, and can move slowly back and forth along the fin direction of the evaporator to be treated, so that the cleaning agent can penetrate the evaporator to be treated for better cleaning effect.

By introducing gas into the air chamber at the front end of the plastic slats and adjusting the thickness of the front end, the correcting slats can fill and compress the fins. The pressure from adjacent slats naturally flattens the fins, and combined with the movement of the correcting slats, effectively corrects the fins, significantly improving the correction effect of the device.

This ensures complete cleaning of the evaporator. The cleaning agent spraying device can be raised and lowered to adhere to the evaporator and spray the cleaning agent, allowing it to penetrate the evaporator for better cleaning results. The combination of the nozzle and brush plate allows for brushing the fins while rinsing off residual cleaning agent, effectively removing even strongly adsorbed stains. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0036] like Figure 1-15As shown, a plate heat exchanger cleaning device includes a water collection tank 1, a fixing system, a straightening system, a spraying system, and a cleaning system. The fixing system is located on both sides of the water collection tank 1; the straightening system is located in front of the water collection tank 1; the spraying system is located on the outside of the water collection tank 1; the straightening system is connected to the cleaning system; the fixing system clamps and fixes the evaporator 100 to be treated, and rotates the evaporator 100 to be treated so that the fins are close to each system when the straightening system, spraying system, and cleaning system are working; the straightening system straightens the fins by bringing them close to the system; the spraying system lowers when the evaporator 100 to be treated is horizontal to spray air conditioning cleaning agent onto the fins; and the cleaning system then cleans the fins after straightening and spraying the cleaning agent.

[0037] Existing technology involves disassembling the outdoor unit of the air conditioner, spraying air conditioner cleaner onto the fins from one side, and rinsing with a water gun. However, cleaning the fins from one side leaves blind spots and results in poor cleaning effectiveness. Existing technology also directly uses fin straightening combs or brushes specifically designed for air conditioner fins to straighten the folded fins on the evaporator of the outdoor unit. While these combs or brushes can achieve some straightening effect, the results are not as good as expected, and their application to different fin spacings is limited, failing to provide a good fit for the fins during straightening.

[0038] To address this issue, the present invention proposes a plate heat exchanger cleaning device. During operation, the evaporator 100 to be treated is manually removed from the outdoor unit of the air conditioner. A fixing system then secures the evaporator 100 above the water collection tank 1. The fixing system switches the evaporator 100 to a vertical position. A straightening system close to one side of the evaporator 100 straightens the fallen fins. After one side is straightened, the fixing system rotates the remaining three sides of the evaporator 100 so that they face the straightening system. The straightening system then sequentially straightens the remaining three sides of the evaporator 100.

[0039] After the correction is completed, the fixing system switches the evaporator 100 to be treated to a horizontal position. The spraying system lowers and approaches the evaporator 100 to spray air conditioning cleaning agent. At the same time, the spraying system slowly reciprocates along the fin direction. After the air conditioning cleaning agent has soaked into the evaporator 100, the spraying system rises. The fixing system switches the evaporator 100 to be treated to an inclined position. The correction system drives the cleaning system to face the evaporator 100. The cleaning system rinses the side of the evaporator 100 that is close to it. After one side of the evaporator 100 is rinsed, the fixing system tilts the other three sides of the evaporator 100 towards the cleaning system. The cleaning system rinses the other three sides of the evaporator 100. After cleaning, all systems are reset, and the evaporator 100 is disassembled manually for subsequent processing.

[0040] This invention uses a fixing system to switch the tilt angle of the evaporator 100 to be treated, which facilitates the subsequent spraying and cleaning systems to spray and clean the evaporator 100. Furthermore, there are no dead angles during the cleaning process, achieving complete cleaning of the evaporator 100. The spraying system can be raised and lowered to fit the evaporator 100 to spray the cleaning agent, and can slowly reciprocate along the fin direction of the evaporator 100 to allow the cleaning agent to penetrate the evaporator 100 for better cleaning results.

[0049] The brushing assembly includes a fifth push rod 411, a first connecting shaft 412, a third connecting rod 413, a pin 414, a second connecting shaft 415, and a brush plate 416; a fifth push rod 411 is mounted on the upper and lower sides of the sixth connecting block 405; the sixth connecting block 405 is rotatably connected to the first connecting shaft 412; two third connecting rods 413 are rotatably connected to each side of the first connecting shaft 412; a second connecting shaft 415 is fixed between the two upper third connecting rods 413; another second connecting shaft 415 is fixed between the two lower third connecting rods 413; the third connecting rods 413 and the second connecting shaft 415 are connected by a pin 414; a brush plate 416 is fixed to each of the two second connecting shafts 415; the brush plate 416 is brought close to the fins by the fifth push rod 411 and works with the nozzle 409 to brush the fins.

[0050] The mechanical gripper 1011 is equipped with a rubber pad to firmly clamp the evaporator 100 to be processed.

[0051] The 2019 plastic slats have smooth chamfered edges.

[0052] The brush bristles of brush plate 416 have hard bases and soft heads to maintain the shape of the bristles while preventing damage to the fins.

[0053] In the specific operation of this invention, the evaporator 100 to be treated is first manually removed from the outdoor unit of the air conditioner and placed above the water collection tank 1, i.e., in the middle of the fixing system. Then, the mechanical gripper 1011 is controlled to clamp and fix the evaporator 100 to be treated. At this time, the evaporator 100 to be treated is vertically fixed above the water collection tank 1. Figure 2 The state shown;

[0054] It should be noted that the mechanical gripper 1011 can be moved left and right by the cooperation of the first guide rail 102 and the first moving block 103 to adapt to the width of the evaporator 100 to be processed; the mechanical gripper 1011 can be moved back and forth by the cooperation of the second guide rail 107 and the second moving block 108 to adapt to the size of the evaporator 100 to be processed.

[0055] It is important to note that before fixing the evaporator 100 to be treated, the correction system and cleaning system should be adjusted to a state that will not affect the placement of the evaporator 100. After the evaporator 100 is vertically fixed, the second drive motor 2010 is controlled to drive the worm gear 2011 to rotate, which in turn drives the worm wheel 2012 and the fifth guide rail 205 to rotate, thereby driving the correction system and cleaning system to rotate and aligning the correction system towards the evaporator 100 to be treated. Figure 2 The state shown;

[0056] Then, by controlling the fourth moving block 203 on the fourth guide rail 202 to move left and right, the plastic sliding piece 2019 moves left and right; by controlling the fifth moving block 206 on the fifth guide rail 205 to move up and down, the plastic sliding piece 2019 moves up and down; by controlling the first micro motor 207 and the second micro motor 2014 to work together to make the plastic sliding piece 2019 swing; and by controlling the first push rod 208 to extend and retract, the plastic sliding piece 2019 moves closer to the position of the folded fins on the evaporator 100 to be treated, thus realizing the multi-dimensional movement of the plastic sliding piece 2019.

[0057] It should be noted that at this time, the distance between adjacent plastic slats 2019 is greater than the fin spacing; subsequently, by controlling the second push rod 211 to drive the first connecting rod 212, connecting plate 213 and second connecting rod 214 to squeeze the plastic slats 2019 at both ends, the buffer pad 215 is compressed, thereby reducing the distance between the plastic slats 2019 to adapt to the fin spacing. Then, the first push rod 208 is controlled to extend so that the plastic slats 2019 are inserted into the fin gap on the surface of the evaporator 100 to be treated, and then the distance is reduced by the first connecting rod 214. Gas is introduced into the air chamber 2019a inside the plastic sliding plate 2019 through the connecting pipe 2016 and the rubber hose 2020, causing the plastic sliding plate 2019 to expand and squeeze the fins. Then, the fifth moving block 206 on the fifth guide rail 205 is controlled to move up and down, causing the plastic sliding plate 2019 to slide up and down to correct the fins. After the correction of the fins on one side of the evaporator 100 to be treated is completed, the plastic sliding plate 2019 is reset, that is, pulled out from the fins without affecting the subsequent rotation of the evaporator 100 to be treated.

[0058] Then, by controlling the first drive motor 112 to drive the first spur gear 113 to rotate, the first spur gear 113 drives the inner gear 114 to rotate, thereby the inner gear 114 drives the ring frame 106, the rotating ring 105, the second guide rail 107, the second moving block 108, the third guide rail 109, the third moving block 1010 and the mechanical gripper 1011 to rotate, and then the mechanical gripper 1011 drives the evaporator 100 to be processed to rotate, and switches the other three fins of the evaporator 100 to face the plastic slitting plate 2019 respectively, and repeats the above correction process;

[0059] Next, the evaporator 100 to be treated is switched to a horizontal state by switching components; then, the second connecting pipe 307 is rotated by controlling the third micro motor 3012, so that the umbrella-shaped nozzle 3010 faces downward toward the evaporator 100 to be treated; by controlling the four third push rods 302 to descend, the third support plate 303 is lowered, which in turn lowers the spraying component composed of the second connecting pipe 307, the third connecting pipe 308, the fourth connecting pipe 309 and the umbrella-shaped nozzle 3010, so that the umbrella-shaped nozzle 3010 is close to the evaporator 100 to be treated; then, by controlling the two third connecting pipes 3012 to rotate, the second connecting pipe 307, the third connecting pipe 308, the fourth connecting pipe 309 and the umbrella-shaped nozzle 3010 are lowered, so that the umbrella-shaped nozzle 3010 is close to the evaporator 100 to be treated; and then, by controlling the four third push rods 302 to descend, the third support plate 303 is lowered, which in turn lowers the spraying component composed of the second connecting pipe 307, the third connecting pipe 308, the fourth connecting pipe 309 and the umbrella-shaped nozzle 3010 are lowered, so that the umbrella-shaped nozzle 3010 is close to the evaporator 100 to be treated; and then, by controlling the two third connecting pipes 3012 to rotate, the second connecting pipe 3010 is lowered, so that the second connecting pipe 3010 faces downward toward the evaporator 100 to be treated. 8. Air conditioning cleaning agent is introduced, allowing it to flow through the second connecting pipe 307 and the fourth connecting pipe 309 to the umbrella-shaped nozzle 3010. At the same time, the umbrella-shaped nozzle 3010 is controlled to start spraying. Meanwhile, the sixth moving block 305 begins to reciprocate along the sixth guide rail 304. After the fins of the evaporator 100 to be treated are soaked with the air conditioning cleaning agent, the umbrella-shaped nozzle 3010 stops operating. The four third push rods 302 push the third support plate 303 to lift the spraying component. The third micro motor 3012 drives the second connecting pipe 307 to rotate, causing the umbrella-shaped nozzle 3010 to reset.

[0060] Subsequently, by controlling the first drive motor 112 to switch the evaporator 100 to the tilted state, the second drive motor 2010 drives the fifth guide rail 205 to rotate, so that the nozzle 409 faces the evaporator 100. By controlling the fourth moving block 203 on the fourth guide rail 202 to move left and right, the nozzle 409 moves left and right. The fifth guide rail 205 on the seventh moving block 401 moves up and down, which in turn moves the nozzle 409 up and down. The fourth micro motor 402 and the fifth micro motor 406 are controlled to work together to make the nozzle 409 swing. The system controls the extension and retraction of the fourth push rod 403 to bring the nozzle 409 close to the position of the folded fins of the evaporator 100 to be treated. After connecting clean water to the fifth connecting pipe 408, the system controls the opening of each nozzle 409 to start spraying water to rinse the evaporator 100 to be treated. At the same time, through the cooperation of the fourth guide rail 202 and the fourth moving block 203, the cooperation of the seventh moving block 401 and the fifth guide rail 205, and the cooperation of the fourth micro motor 402, the fifth micro motor 406 and the fourth push rod 403, the nozzle 409 moves slowly along the surface of the evaporator 100 to be treated and performs rinsing.

[0061] Furthermore, the sixth micro motor 407 drives the fifth connecting pipe 408 to rotate slightly, which in turn drives the nozzle 409 to rotate slightly, realizing the fine adjustment of the direction of the nozzle 409, increasing the rinsing area and making the cleaning more thorough.

[0062] Simultaneously, by controlling the two fifth push rods 411, the two brush plates 416 can be pushed respectively, so that the upper and lower brush plates 416 move forward and drive the two second connecting shafts 415 to link the two third connecting rods 413 on each side. The two third connecting rods 413 on the same side rotate around the first connecting shaft 412 and move closer to each other, so that the two brush plates 416 approach the nozzle 409 and cooperate with the nozzle 409 to perform brushing, while realizing the self-cleaning of the brush plates 416.

[0063] Afterwards, by controlling the nozzle 409 to reset, and then by controlling the first drive motor 112 to drive the evaporator 100 to be treated to switch to an inclined state with the other three sides facing the cleaning system in sequence, the evaporator 100 to be treated is cleaned again as described above.

[0064] Afterwards, the control system, spraying system, and cleaning system are switched to a state that does not affect the manual removal of the evaporator 100 to be treated, and then the evaporator 100 to be treated is removed manually.

[0065] It should be understood that the above description is for illustrative purposes only and is not intended to limit the invention. Those skilled in the art will understand that variations of the invention are included within the scope of the claims herein.
