Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to an industrial air conditioning cooler. Background Technology

[0002] Industrial air conditioning refers to large-scale air conditioning systems specifically designed, manufactured, and installed for industrial production and commercial applications. Compared to household air conditioners, industrial air conditioners have stronger cooling capacity, can adapt to harsh working environments, and are more durable.

[0003] In related technologies, the air conditioner can deliver clean and odorless cold air by continuously cleaning the air outlet filter. However, during the use of industrial air conditioners, dust accumulates on the fan blades. Due to the low temperatures in winter, industrial air conditioners are usually turned off to save energy. During the long period of shutdown, bacteria can grow on the fan blades, resulting in odors in the air delivered after the air conditioner is turned on, affecting the working environment and harming the health of the workers.

[0004] Chinese Patent CN111271858B discloses a fan blade self-cleaning device and an air conditioner. The fan blade self-cleaning device includes a guide device, a cleaning device, and a drive device. The guide device is disposed on the air duct of the air conditioner and includes a first guide shaft disposed vertically on the air duct and a second guide shaft disposed parallel to the first guide shaft. The end of the cleaning device is disposed on the first guide shaft by a first fixing unit, and the middle part of the cleaning device is disposed on the second guide shaft by a second fixing unit. The drive device includes a first drive mechanism for driving the first guide shaft to move up and down. The first drive mechanism includes a first drive motor mounted on the top of the guide device, a first lead screw disposed parallel to the first guide shaft, and a first nut sleeved on and meshing with the first lead screw. The first nut is fixed on the first guide shaft.

[0005] The aforementioned self-cleaning fan blade device drives a first lead screw to rotate via a first drive motor, causing the first lead screw nut to move up and down axially along the first guide shaft. This causes the cleaning device to unfold after rotation and swing around its connection with the second guide shaft, thereby cleaning the blades. However, after prolonged use, a large amount of dust and bacteria will adhere to the cleaning device, reducing its effectiveness in cleaning the fan blades, resulting in dust or bacteria constantly adhering to the blades. Summary of the Invention

[0006] This invention provides an industrial air conditioning cooler, which aims to solve the problem in related technologies where the cleaning device itself is difficult to clean, resulting in reduced cleaning effect.

[0007] The industrial air conditioning cooler of the present invention includes: a frame, a fan, a compressor, and condenser pipes;

[0008] The fan, the compressor, and the condenser are all mounted on the frame. The compressor is used to draw in outside air and discharge it to the fan. The condenser is used to cool the air discharged to the fan. The fan is used to discharge the cooled air.

[0009] The fan includes a fan housing, a drive motor, fan blades, and a cleaning device. The drive motor is located inside the fan housing, and the fan blades are rotatably mounted inside the fan housing. The drive motor drives the fan blades to rotate. The cleaning device includes a drive mechanism, a moving ring, a rotating seat, a first scraper, a second scraper, and a nozzle. The moving ring is located inside the fan housing, and the drive mechanism drives the moving ring to move axially along the fan housing. The rotating seat is rotatably mounted on the fan housing. The first scraper and the second scraper are spaced apart on the rotating seat and can respectively adhere to the two side walls of the fan blades. Each of the first and second scrapers is provided with a water storage box. The nozzle is located on the first and second scrapers and can communicate with the water storage box.

[0010] Beneficial effects: When the fan is working normally, the first and second scrapers are distributed parallel to the fan blades at intervals. When the fan stops, the fan blades stop in a fixed position. At this time, the fan blades are located next to the cleaning device. The rotating mechanism drives the rotating seat to rotate 90 degrees, so that the first and second scrapers are distributed perpendicular to the fan blades and are in close contact with the fan blades. When the drive mechanism drives the moving ring to move inward along the axial direction of the fan casing, the first and second scrapers can scrape off the dust and impurities on the fan blades. After the first and second scrapers have finished cleaning the fan blades, the nozzle is connected to the water storage box and sprays water onto the first and second scrapers to wash away the dust and impurities attached to the first and second scrapers, thus cleaning the first and second scrapers.

[0011] Preferably, the moving ring is provided with a rotating mechanism, which includes a drive ring, a first drive member, a rotating shaft, a cam, and a connecting rod. The drive ring is slidably fitted inside the moving ring. The first drive member is disposed on the moving ring and is used to drive the drive ring to move axially along the moving ring. The rotating shaft is fixedly connected to the rotating seat. The large-diameter end of the cam is connected to the end of the rotating shaft. One end of the connecting rod is hinged to the small-diameter end of the cam, and the other end of the connecting rod passes through the moving ring and is hinged to the drive ring.

[0012] Preferably, the first scraper is fixedly connected to the rotating seat, the second scraper is distributed parallel to and spaced apart from the first scraper, the rotating seat is provided with a sliding groove, the second scraper is provided with a matching rod, the matching rod is slidably engaged in the sliding groove, and the second scraper is connected to the rotating seat through a first elastic element.

[0013] Beneficial effect: The first elastic element is always in a stretched state, thereby applying a pulling force towards the first scraper to the second scraper, ensuring that the first and second scrapers can be in close contact with the fan blade.

[0014] Preferably, the movable ring is provided with a limiting groove, and a limiting block is provided in the limiting groove. One end of the limiting block is in close contact with the side wall of the limiting groove, and the other end is a beveled structure with a gap between the beveled structure and the other side wall of the limiting groove. The mating rod can pass through the rotating seat and extend into the limiting groove, and abut against the limiting block. When the rotating seat rotates relative to the movable ring, the mating rod can move along the limiting groove.

[0015] Beneficial effects: In the initial state, the mating rod abuts against the limiting block, which facilitates the blades to extend between the first and second scrapers when the rotating seat rotates. As the rotating seat rotates to change the first and second scrapers from being parallel to the fan blades to being perpendicular to them, the mating rod moves along the limiting block and gradually approaches the inclined end of the limiting block. Under the action of the first elastic element, the end of the mating rod always abuts against the limiting block. When the mating rod moves to the inclined end of the limiting block, it moves at an angle along the inclined surface of the limiting block, thereby reducing the gap between the second scraper and the first scraper until both the first and second scrapers are in close contact with the fan blades.

[0016] Preferably, the end of the second scraper is provided with a third scraper, the third scraper is slidably engaged with the second scraper, the third scraper is connected to the second scraper through a second elastic member, and the third scraper can abut against the first scraper, so that a cleaning groove is formed between the first scraper, the second scraper, the third scraper and the rotating seat.

[0017] Its effect is that the third scraper can scrape the side wall of the fan blades, preventing the formation of cleaning dead corners.

[0018] Preferably, the water storage box is slidably fitted on the first scraper or the second scraper and connected to the first scraper or the second scraper through a third elastic element. The first scraper and the second scraper are provided with a first connecting plate and a second connecting plate on both sides. The plurality of nozzles are divided into four groups and are distributed at intervals on two of the first connecting plates and two of the second connecting plates. The water storage box is provided with two sets of communication ports on both sides, and the two sets of communication ports correspond to two sets of nozzles on the first connecting plate and the second connecting plate. The water storage box can communicate with the nozzles through the communication ports.

[0019] Its effect is as follows: Under normal circumstances, the third elastic element is in its natural state. At this time, the water storage box is connected to the nozzle on the first connecting plate. After the first and second scrapers scrape the blades, the nozzle on the first connecting plate sprays water to rinse the area on the fan blades where dust and impurities have been scraped off, preventing dust and impurities from remaining. When the moving ring moves inward to its limit and stops moving inward, the water storage box is squeezed to overcome the elastic force of the third elastic element and moves relative to the first or second scraper, so that the water storage box is connected to the nozzle on the second connecting plate. The nozzle on the second connecting plate sprays water to wash away the dust that has accumulated between the first and second scrapers and the fan blades during the scraping process, ensuring the cleanliness of the first and second scrapers.

[0020] Preferably, the water storage box is provided with a first stop and a second stop on both sides, and the first stop and the second stop can stop against the first scraper or the second scraper, thereby limiting the movement range of the water storage box.

[0021] Preferably, the driving mechanism includes a second driving member, a lead screw, and a guide rod. The lead screw is rotatably connected to the fan housing. The second driving member is disposed on the fan housing and is used to drive the lead screw to rotate. The moving ring is threadedly engaged with the lead screw. The guide rod is distributed parallel to the lead screw at intervals and is fixedly connected to the fan housing. The moving ring is slidably engaged with the guide rod.

[0022] Preferably, the bottom of the fan housing is provided with a drain outlet, and a closing plate is provided at the drain outlet. The closing plate is connected to the fan housing through a fourth elastic element, and the closing plate can close the drain outlet.

[0023] Preferably, the rotating seat, the first scraper, the second scraper, and the third scraper are all provided with rubber pads.

[0024] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0025] According to the industrial air conditioning cooler of the present invention, when the fan is working normally, the first scraper and the second scraper are distributed parallel to the fan blades at intervals. When the fan stops, the fan blades stop at a fixed position. At this time, the fan blades are located next to the cleaning device. The rotating mechanism drives the rotating seat to rotate 90 degrees, so that the first scraper and the second scraper are distributed perpendicular to the fan blades and are in close contact with the fan blades. When the driving mechanism drives the moving ring to move inward along the axial direction of the fan housing, the first scraper and the second scraper can scrape off the dust and impurities on the fan blades. After the first scraper and the second scraper have finished cleaning the fan blades, the nozzle is connected to the water storage box and sprays water onto the first scraper and the second scraper to wash away the dust and impurities attached to the first scraper and the second scraper, thereby cleaning the first scraper and the second scraper.

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figures 1 to 11 As shown, the industrial air conditioning cooler of the present invention includes: a frame 100, a fan 200, a compressor and a condenser pipe. The frame 100 is used to support the various components. The compressor is used to draw in outside air and discharge it to the fan 200. The condenser pipe is used to cool the air discharged to the fan 200. The fan 200 is used to discharge the cooled air.

[0042] like Figure 1 As shown, specifically, the frame 100 is a cuboid frame structure with a first layer and a second layer. The compressor can be placed on the first layer, and the fan 200 can be placed on the second layer. The four condenser pipes are located at the four prism positions of the frame 100. The compressor is connected to the condenser pipes through pipes, and the condenser pipes are connected to the fan 200 through pipes.

[0043] like Figures 1 to 3As shown, the fan 200 includes a fan housing 201, a drive motor 203, fan blades, and a cleaning device. The fan housing 201 is a cylindrical structure with an upward-facing air outlet. Air inlets are located on both the left and right sides of the fan housing 201, and these inlets are connected to a condenser pipe via pipes. Two sets of fan blades are installed inside the fan housing 201. Each set of fan blades consists of two fixing rings 2021 and multiple blades 2022. The two fixing rings 2021 are parallel and spaced apart, and both rotate with the fan housing 201. The multiple blades 2022 are located on the two... The fixed rings 2021 are evenly spaced around each other along their circumference. Each blade 2022 is fixedly connected to two fixed rings 2021 at both ends. The drive motor 203 is located inside the fan housing 201 and is fixedly connected to the fan housing 201 via a bracket. The output end of the drive motor 203 is fixedly connected to the fixed rings 2021, thereby driving the fixed rings 2021 to rotate, which in turn causes the fan blades to rotate inside the fan housing 201. This allows the cold air entering from both sides of the fan housing 201 to be discharged towards the air outlet of the fan housing 201. The compressor and condenser in this embodiment are conventional compressors and condenser pipes, and therefore are not shown in the figures.

[0044] like Figure 3 and Figure 4 As shown, there are two cleaning devices, one for each set of fan blades. Each cleaning device includes a drive mechanism, a moving ring 1, a rotating seat 3, a first scraper 5, a second scraper 6, a water storage box 8, and a nozzle 9. The moving ring 1 is a circular ring structure that slides within the fan housing 201. The fan housing 201 is equipped with a drive mechanism, which includes a second drive component 41, a lead screw 22, and a guide rod 23. The second drive component 41 is fixedly mounted on the side wall of the fan housing 201 and is a motor. The lead screw 22 is rotatably engaged with the fan housing 201 and is connected to the second drive component 41. The output end of component 41 is fixedly connected. The second driving component 41 can drive the lead screw 22 to rotate. The guide rod 23 is fixedly connected to the side wall of the fan housing 201, and the guide rod 23 and the lead screw 22 are distributed parallel to each other. The moving ring 1 is provided with a threaded hole and a mating hole. The moving ring 1 is threadedly engaged with the lead screw 22 through the threaded hole, and also slidably engaged with the guide rod 23 through the mating hole. When the second driving component 41 drives the lead screw 22 to rotate, the lead screw 22 drives the moving ring 1 to move along the axial direction of the fan housing 201. The guide rod 23 is used to prevent the moving ring 1 from rotating and can also prevent the moving ring 1 from tilting when moving.

[0045] like Figures 5 to 7As shown, the moving ring 1 has multiple mating seats 101 spaced circumferentially on it. Each mating seat 101 is rotatably fitted with a rotating seat 3. The number of rotating seats 3 is the same as the number of blades 2022 in each group of fan blades, and each rotating seat 3 corresponds to one blade 2022. The moving ring 1 is equipped with a rotating mechanism, which includes a drive ring 42, a first drive member 21, a rotating shaft 43, a cam 44, and a connecting rod 45. The moving ring 1 is a hollow structure. The drive ring 42 is slidably fitted inside the moving ring 1 and can move along the axial direction of the moving ring 1. The first drive member 21 is fixedly mounted on the moving ring 1. The first drive member 21 is an electric push rod, and its output end is fixedly connected to the drive ring 42. The first drive member 21 can provide power to the drive ring 42, thereby driving the drive ring 42. Ring 42 moves axially along the movable ring 1. A rotating shaft 43 is fixedly mounted on a rotating seat 3, coaxially distributed with the rotating seat 3, and its bottom end extends out of the rotating seat 3. The large-diameter end of the cam 44 is fixedly connected to the bottom end of the rotating shaft 43. The movable ring 1 has an opening through which a connecting rod 45 can extend into the movable ring 1. One end of the connecting rod 45 is hinged to the small-diameter end of the cam 44, and the other end is hinged to the drive ring 42. The width of the opening is greater than the width of the connecting rod 45, allowing the connecting rod 45 to swing within the opening. When the drive ring 42 moves within the movable seat, the drive ring 42 drives the cam 44 to rotate via the connecting rod 45. The cam 44 then drives the rotating seat 3 to rotate around the rotating shaft 43 via the rotating shaft 43.

[0046] like Figure 5 , Figures 7 to 11As shown, the first scraper 5 is fixedly connected to the bottom end of the rotating seat 3. The rotating seat 3 is provided with a sliding groove that passes through the rotating seat 3. A matching rod 61 is fixedly provided on the second scraper 6. The matching rod 61 is slidably engaged in the sliding groove. The second scraper 6 is elastically connected to the rotating seat 3 through a first elastic element 62. The first elastic element 62 is a spring, one end of which is fixedly connected to the second scraper 6 and the other end of which is fixedly connected to the rotating seat 3. The second scraper 6 and the rotating seat 3 are slidably engaged and are distributed parallel to and spaced apart from the first scraper 5. The matching rod 61 can move along the sliding groove in the sliding groove, so that the second scraper 6 can move closer to or away from the first scraper 5. The mating seat 101 is provided with a limiting groove 1011, which is an arc-shaped groove. A limiting block 1012 is provided inside the limiting groove 1011. The limiting block 1012 is an arc-shaped structure, and its curvature is the same as that of the mating difference. One end of the limiting block 1012 is in close contact with the side wall of the limiting groove 1011, and the other end is a sloped structure. There is a gap between the sloped structure and the other end side wall of the limiting groove 1011. The first elastic element 62 is always in a stretched state. In normal conditions, the end of the mating rod 61 abuts against the limiting block 1012, thereby ensuring that the first scraper 5 and the second scraper 6 are far apart from each other. When the rotating seat 3 rotates, the mating rod 61 moves along the limiting block 1012. When the mating rod 61 moves to the inclined end of the limiting block 1012, the mating rod 61 moves along the inclined end of the limiting block 1012. Under the contraction elastic force of the first elastic member 62, the second scraper 6 gradually approaches the first scraper 5.

[0047] like Figures 8 to 11 As shown, a third scraper 7 is also provided on the second scraper 6. The second scraper 6 has a mounting groove that extends along the length of the second scraper 6. A mounting rod 71 is fixedly provided on the third scraper 7. The mounting rod 71 is slidably fitted in the mounting groove. A second elastic element 72, which is a spring, is provided between the mounting rod 71 and the mounting groove. The mounting rod 71 is a hollow rod. The second elastic element 72 is located inside the mounting rod 71. One end of the second elastic element 72 is fixedly connected to the end of the mounting rod 71 near the third scraper 7, and the other end is connected to the groove of the mounting groove. The wall is fixedly connected, and the third scraper 7 is perpendicular to the second scraper 6. When the second scraper 6 moves toward the first scraper 5 to its limit, the third scraper 7 stops against the first scraper 5. At this time, a rectangular cleaning groove can be formed between the rotating seat 3, the first scraper 5, the second scraper 6 and the third scraper 7. The cleaning groove can be tightly attached to the periphery of the blade 2022. Rubber pads are provided on the rotating seat 3, the first scraper 5, the second scraper 6 and the third scraper 7, so that the four sides of the cleaning groove are covered with rubber pads. The rubber pads can be tightly attached to the blade 2022.

[0048] like Figures 8 to 10As shown, both the first scraper 5 and the second scraper 6 are provided with mating grooves, which are symmetrically distributed. Each mating groove has a water storage box 8 that is slidably fitted inside. The water storage box 8 has a first stop 82 and a second stop 83 on its two sides, which are spaced apart. The first stop 82 can abut against the corresponding side wall of the mating groove, and the second stop 83 can abut against the corresponding side wall on the other side of the mating groove. The water storage box 8 is elastically connected to the first scraper 5 or the second scraper 6 through a third elastic element 81, which is a spring. One end of the third elastic element 81 is fixedly connected to the first stop 82, and the other end is fixedly connected to the first scraper 5 or the second scraper 6. The water storage box 8 can move along the width direction of the first scraper 5 or the second scraper 6. The first stop 82 and the second stop 83 can limit the movement range of the water storage box 8. First connecting plates 10 and 11 are respectively provided on both sides of the first scraper 5 and the second scraper 6. Multiple nozzles 9 are divided into four groups, with one group of nozzles 9 on each of the first connecting plates 10 and 11. Each group of nozzles 9 is evenly spaced along the length of the first connecting plate 10 or the second connecting plate 11. Two sets of connecting ports are provided on both sides of the water storage box 8, allowing the water storage box 8 to communicate with the nozzles 9 on the first connecting plate 10 or the second connecting plate 11 through these ports. A water storage chamber is provided inside the moving ring 1, and a water inlet 84 is provided on the water storage box 8. The water inlet 84 is connected to the water storage chamber inside the moving ring 1 via a flexible hose. The water storage chamber inside the moving ring 1 is connected to an external water tank via a water pipe.

[0049] like Figure 2 As shown, the bottom of the fan housing 201 is also provided with a drain outlet 2011. A closing plate 12 is slidably fitted at the drain outlet 2011. The closing plate 12 is slidably fitted with the fan housing 201 through a fourth elastic element 121. The fourth elastic element 121 is a spring. One end of the fourth elastic element 121 is fixedly connected to the closing plate 12, and the other end is fixedly connected to the fan housing 201.

[0050] The implementation principle of the industrial air conditioning cooler in this embodiment of the invention is as follows:

[0051] When the fan 200 is working normally, the cleaning device remains stationary and does not contact the fan blades to avoid affecting the air delivery of the fan blades. When the fan blades stop rotating, they will stop in a fixed position. At this time, the fan blades are located next to the cleaning device. Under the contraction elastic force of the first elastic element 62, the top surface of the cooperating rod 61 and the limiting block 1012 abuts against each other, thereby creating a gap between the third scraper 7 and the first scraper 5.When the blade 2022 needs cleaning, the first driving member 21 drives the driving ring 42 to move outward. The driving ring 42 pulls the cam 44 through the connecting rod 45, thereby causing the cam 44 to rotate 90 degrees. The cam 44 drives the rotating seat 3 to rotate through the rotating shaft 43, thereby changing the first scraper 5 and the second scraper 6 from being parallel to the blade 2022 to being perpendicular to the blade 2022. At the same time, the blade 2022 is located between the first scraper 5 and the second scraper 6. During the rotation of the rotating seat 3, the cooperating rod 61 moves along the limiting block 1012 and gradually approaches the inclined end of the limiting block 1012. When the cooperating rod 61 moves to the inclined end of the limiting block 1012, under the action of the contraction elastic force of the first elastic member 62, The end of the mating rod 61 moves along the inclined end of the limiting block 1012, thereby causing the second scraper 6 to gradually approach the first scraper 5. When the mating rod 61 disengages from the inclined end of the limiting block 1012 and abuts against the bottom surface of the limiting groove 1011, the third scraper 7 abuts against the first scraper 5. At this time, under the contraction elastic force of the first elastic element 62, the rubber pads on the first scraper 5 and the second scraper 6 are tightly attached to the blade 2022. Under the contraction elastic force of the second elastic element 72, the rubber pads on the third scraper 7 and the rubber pads on the rotating seat 3 are respectively tightly attached to the two side walls of the blade 2022. Then, the first driving element 21 drives the lead screw 22 to rotate, thereby driving the moving ring 1 to move inward. The moving ring 1 moves inward. During the movement, the rubber pads on the rotating seat 3, the first scraper 5, the second scraper 6, and the third scraper 7 can scrape off the dust and impurities attached to the blade 2022. The scraped-off impurities collect at the corner formed between the inner sidewall of the rotating seat 3, the first scraper 5, the second scraper 6, and the third scraper 7 and the blade 2022. As the moving ring 1 moves inward, the third elastic element 81 is in its natural state. At this time, the water storage box 8 is connected to the nozzle 9 on the first connecting plate 10. At this time, the external water pump pumps water into the moving ring 1. The water in the moving ring 1 enters the water storage box 8 through the hose, and then is sprayed out through the nozzle 9 on the first connecting plate 10, thereby cleaning the rotating seat 3, the first scraper 5, the second scraper 6, and the third scraper 7. The blades 2022 of the scraper 7, which have undergone scraping operations, are rinsed to prevent dust and impurities from remaining on the blades 2022. As the moving ring 1 moves inward, the water storage box 8 gradually approaches the inner fixed ring 2021 and stops against the fixed ring 2021, thereby causing the water storage box 8 to overcome the elastic force of the third elastic element 81 and move outward relative to the first scraper 5 or the second scraper 6. When the moving ring 1 stops moving, the water storage box 8 connects with the spray hole on the second connecting plate 11. At this time, the spray hole on the second connecting plate 11 sprays water to wash away the dust and impurities that have accumulated at the corner between the inner sidewall of the rotating seat 3, the first scraper 5, the second scraper 6 and the third scraper 7 and the blades 2022, thus achieving self-cleaning of the cleaning device.

[0052] During the cleaning process, the wastewater mixed with dust will collect at the bottom of the fan housing 201. As the moving ring 1 moves inward, the cleaning device located at the bottom of the moving ring 1 can stop against the closing plate 12 and push the closing plate 12 to overcome the elastic force of the fourth elastic element 121, thereby opening the drain outlet 2011. The wastewater mixed with dust can be discharged from the fan housing 201 through the drain outlet 2011.

[0053] After cleaning is completed, the first driving member 21 drives the lead screw 22 to rotate in the opposite direction, thereby causing the moving ring 1 to move outward. When the moving ring 1 moves outward to its limit, the second driving member 41 drives the driving ring 42 to move inward. The driving ring 42 pushes the cam 44 to rotate in the opposite direction by 90 degrees through the connecting rod 45. The cam 44 drives the rotating seat 3 to rotate in the opposite direction by 90 degrees. During the rotation of the rotating seat 3, the cooperating rod 61 moves along the top surface of the limiting block 1012 under the action of the first elastic member 62, thereby causing the second scraper 6 to gradually move away from the first scraper 5, and the third scraper 7 to disengage from the first scraper 5. The blade 2022 can disengage from the cleaning groove through the gap between the third scraper 7 and the first scraper 5. When the rotating seat 3 stops rotating, the cleaning device is reset.

[0054] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
