Description

Technical Field

[0001] This invention relates to the field of energy-saving air conditioning cooling fan technology, specifically to an energy-saving air conditioning cooling fan with protective functions. Background Technology

[0002] Energy-saving air conditioning cooling fans are highly efficient devices that achieve cooling through evaporative cooling. Their core function is to convert hot outside air into cool airflow through heat exchange with the air via a water curtain or ice curtain. They also feature low energy consumption (typically less than 1 kWh per hour).15 These devices are widely used in large spaces such as factories and workshops, offering advantages such as rapid cooling (4-15℃), improved air quality, and energy conservation. However, despite their excellent performance in energy consumption and cooling efficiency, energy-saving air conditioning cooling fans still have the following significant issues in dustproof and moisture-proof design:

[0003] 1. Insufficient dust prevention: Cooling fans rely on filters to block dust, but after long-term operation, the filters are easily clogged by dust, hair, etc., leading to a decrease in airflow or even shutdown. If the filters are not cleaned regularly, the evaporative cooler will develop an odor due to dust accumulation, and frequent disassembly and cleaning are required, resulting in high maintenance costs.

[0004] 2. Weak moisture-proof design: The inside of the equipment may become damp due to excessive ambient humidity, which may cause the motor to short-circuit or rust. If the cooling fan is not waterproof or sealed, the failure rate will increase significantly.

[0005] Therefore, it is necessary to design an energy-saving air conditioning cooling fan with protective functions to improve dust and moisture protection. Summary of the Invention

[0042] 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, and 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.

[0043] Please see Figure 1-7 The present invention provides a technical solution: an energy-saving air conditioning cooling fan with protective function, including a housing 1, the housing 1 including an air inlet pipe 2, a middle section pipe 3, and an air outlet pipe 4. The air inlet pipe 2 and the air outlet pipe 4 are both flared structures, and the middle section pipe 3 is a cylindrical structure. The air inlet pipe 2, the middle section pipe 3, and the air outlet pipe 4 are all connected by flanges and quick-release bolts. A rubber sealing ring is embedded at the joint of the flange to seal the joint of the flange.

[0044] like Figure 2 A drive motor 5 is installed inside the middle section pipe 3. A motor housing 6 is fitted on the outer wall of the drive motor 5. Support rods 7 are fixedly connected to the four corners at both ends of the motor housing 6 along the length direction. The end of the support rod 7 away from the motor housing 6 is fixedly connected to the pipe wall of the middle section pipe 3.

[0045] The output shaft of the drive motor 5 is fixedly connected to a bushing 8. Several fan blades 9 are detachably connected to the outer circumferential wall of the bushing 8. The fan blades 9 are evenly distributed in a circle with the center of the bushing 8 as the center. The drive motor 5 drives the fan blades 9 to rotate.

[0046] A first filter screen 10 is provided at the end of the air inlet pipe 2 that is away from the middle section pipe 3, and a second filter screen 11 is provided at the end of the air outlet pipe 4 that is away from the middle section pipe 3.

[0047] Both the first filter screen 10 and the second filter screen 11 are made of nano-hydrophobic dustproof filter screen, which is hydrophobic and has a mesh diameter of 1mm.

[0048] Both the first filter screen 10 and the second filter screen 11 are coated with a protective coating made of titanium dioxide. Under light, titanium dioxide can generate highly active substances such as hydroxyl radicals and superoxide radicals, which can decompose organic pollutants and bacteria adsorbed on the surface of the filter screen, thereby improving the self-cleaning effect of the filter screen.

[0049] A grid 12 is provided on the side of the first filter screen 10 away from the middle section pipe 3. It is made of stainless steel and has a mesh diameter of 10mm. It is used to block large particles of foreign objects from entering and resist external mechanical impact. The first filter screen 10, the second filter screen 11 and the grid 12 are all detachable for easy cleaning and replacement.

[0050] like Figure 3 A condenser assembly 13 is provided on the side of the first filter screen 10 near the middle section pipe 3. The condenser assembly 13 includes a central cylinder 14, which opens to the middle section pipe 3. The central cylinder 14 is coaxially arranged with the air inlet pipe 2. A connecting plate 15 is fixedly connected inside the central cylinder 14. The connecting plate 15 is horizontally arranged and integrally formed with the central cylinder 14. The end of the connecting plate 15 near the first filter screen 10 along the axis of the central cylinder 14 extends out of the central cylinder 14. Fixing rods 16 are fixedly connected to the four corners of the upper and lower sides of the connecting plate 15. The fixing rods 16 are fixedly connected to the wall of the air inlet pipe 2.

[0051] Several guide vanes 17 are hinged to the outer circumference of the central cylinder 14. The guide vanes 17 are spiral in shape and are evenly distributed around the axis of the central cylinder 14.

[0052] like Figure 4 A connecting shaft 18 is fixedly connected to the root of the guide vane 17, and connecting blocks 19 are rotatably connected to both ends of the connecting shaft 18. The connecting blocks 19 are fixedly connected to the outer wall of the central cylinder 14.

[0053] A gear 20 is fixedly connected to the end of the connecting shaft 18 near the middle section tube 3 along the axial direction through the connecting block 19. A sleeve 21 is nested at the end of the central cylinder 14 near the middle section tube 3. The sleeve 21 is rotatably connected to the central cylinder 14. An outer gear ring 22 is fitted on the outer wall of the sleeve 21 away from the central cylinder. The outer gear ring 22 is fixedly connected to the sleeve 21. An inner gear ring 23 is fixedly connected to the inner wall of the sleeve 21.

[0054] A rotary motor 24 is fixedly connected to the connecting plate 15 inside the central cylinder 14. A gear 25 is fixedly connected to the output end of the rotary motor 24. The gear 25 meshes with the gear of the inner gear ring 23, and the gear 20 meshes with the gear of the outer gear ring 22. The rotary motor 24 drives the gear 20 to rotate, which in turn drives the guide vane 17 to rotate around the connecting shaft 18. By adjusting the angle of the guide vane 17, the airflow resistance is changed.

[0055] Specifically, the angle motor 24 can only adjust the guide vane 17 in one direction, and the adjustable angle threshold is 0°-30°.

[0056] A condensation channel is provided inside the guide vane 17. The condensation channel is an "S" shaped cavity. The input port of the condensation channel is located at the end of the connecting shaft 18 near the first filter screen 10, and the output port of the condensation channel is located at the end of the gear 20 near the middle section pipe 3.

[0057] A miniature condenser 26 is fixedly connected to the side of the connecting plate 15 away from the rotary motor 24. An input branch pipe is fixedly connected to the input port of the condensation channel. The input branch pipe passes through the central cylinder 14, and the input end of the input branch pipe is fixedly connected to the input main pipe through a multi-way valve. The input main pipe is connected to the output end of the miniature condenser 26.

[0058] The output port of the condenser is fixedly connected to an output branch pipe, and the input end of the output branch pipe is fixedly connected to an output main pipe through a multi-way valve. The output main pipe is connected to the input end of the miniature condenser 26, thereby achieving the cooling effect on the guide vanes 17 through the miniature condenser 26.

[0059] like Figure 5 The wall of the air inlet pipe 2 has a step 42 at one end near the middle section pipe 3, and the guide vane 17 is close to the step 42 on one side along the axial direction of the central cylinder 14.

[0060] When the guide vane 17 is adjusted, the diameter of the guide vane 17 acting on the air changes. Therefore, the minimum diameter of the guide vane 17 acting on the air is greater than the inner diameter of the step 42, so that the side of the step 42 blocks the air and prevents the air from entering the middle section pipe 3 directly without passing through the guide vane 17.

[0061] A collection trough 27 is provided on the end of the air inlet duct 2 away from the middle section duct 3, corresponding to the guide vane 17. The collection trough 27 is a semi-circular structure used to collect water condensed from the guide vane 17.

[0062] A water storage box is fixedly connected to the outer wall of the air inlet pipe 2. A water outlet 28 is opened at the bottom of the collection tank 27. The water outlet 28 is connected to the water storage box through a pipe. A filter is installed on the pipe connecting the water outlet 28 to the water storage box. The filter is fixedly connected to the outer wall of the air inlet pipe 2. The filter is a conventional technology and is used to purify and filter water.

[0063] The water storage box is equipped with a liquid level sensor to detect the water level inside the box. The water storage box is fixedly connected to a solenoid valve. When the water level in the water storage box exceeds the upper limit of the liquid level sensor, it will be automatically discharged through the solenoid valve.

[0064] Both the first filter screen 10 and the second filter screen 11 are annular filters. A circular hole 29 is formed at the center of both the first filter screen 10 and the second filter screen 11, and a cleaning component 30 is rotatably connected inside the circular hole 29.

[0065] like Figure 6 The cleaning component 30 includes a rotating shaft 31, which is located inside a circular hole 29. The rotating shaft 31 is rotatably connected to the circular hole 29. Two scrapers 32 are fixedly connected to both ends of the rotating shaft 31 along the axial direction. The two scrapers 32 are arranged opposite to each other. The side of the two scrapers 32 closest to the first filter screen 10 is covered with a wiping cloth. The wiping cloth is made of microfiber and has high water absorption and wear resistance.

[0066] like Figure 7 The scraper 32 has several water outlet holes 33 at the position where it is wrapped by the wiping cloth. The several water outlet holes 33 are arranged in an array. The scraper 32 has a water inlet hole 34 at the position near the rotating shaft 31. A water inlet channel is opened inside the scraper 32, and the water inlet channel connects the water inlet hole 34 and the water outlet hole 33.

[0067] Water enters through the inlet hole 34 and flows out through the outlet hole 33, and is then absorbed by the wiping cloth to clean the first filter screen 10.

[0068] A second drive motor 35 is fixedly connected to the side of the connecting plate 15 near the first filter screen 10. The output shaft of the second drive motor 35 is fixedly connected to the rotating shaft 31. The second drive motor 35 drives the rotating shaft 31 to rotate, thereby causing the scraper 32 to rotate around the rotating shaft 31 in a circle, thereby cleaning the first filter screen 10.

[0069] A hydraulic slip ring 36 is fitted on the rotating shaft 31. The hydraulic slip ring is a conventional technology. As a connecting component, the hydraulic slip ring can transfer liquid to the mechanism on a 360° rotating object. The sliding ring of the hydraulic slip ring 36 is fitted on the rotating shaft 31 and fixedly connected to the rotating shaft 31. The fixed ring of the hydraulic slip ring 36 is fixedly connected to a bracket 43. The end of the bracket 43 away from the hydraulic slip ring 36 is fixedly connected to the inner wall of the air inlet pipe 2.

[0070] The output end of the hydraulic slip ring 36 on the sliding ring is connected to the water inlet 34 through a pipe. The input end of the hydraulic slip ring 36 on the fixed ring is connected to a micro pump through the air inlet pipe 2. The micro pump is fixedly connected to the outer wall of the air inlet pipe 2. The input end of the micro pump is connected to the water storage box. In this way, water is supplied to the water inlet 34 through the micro pump and the hydraulic slip ring 36.

[0071] The cleaning components 30 on the first filter screen 10 and the second filter screen 11 have the same structure. The difference is that the drive motor 35 of the cleaning component 30 on the second filter screen 11 is fitted with a motor housing 37. Support rods 38 are fixedly connected to the four corners of the motor housing 37 along the length direction. The end of the support rod 38 away from the motor housing 37 is fixedly connected to the wall of the air outlet pipe 4.

[0072] The hydraulic slip ring 36 of the cleaning component 30 on the second filter screen 11 is located on the fixed ring. The input end of the slip ring passes through the air outlet pipe 4 and is connected to the micro pump through the multi-way valve.

[0073] The second filter 11 is fixedly connected to a louver 39 on the side away from the middle section pipe 3. The outer frame of the louver 39 is circular, so that the louver 39 can be adapted to the air outlet pipe 4.

[0074] The walls of the air outlet pipe 4 and the air inlet pipe 2 are respectively provided with collection grooves 27 at both ends of the second filter screen 11 and the first filter screen 10. The collection groove 27 is a semi-circular ring structure used to collect water stains flowing down from the first filter screen 10 or the second filter screen 11.

[0075] Both collection tanks 240 have outlets 241 at the bottom, and the outlets 241 are connected to the filter through a multi-way valve pipe.

[0076] An air humidity sensor and an air temperature sensor are fixedly connected to the pipe wall inside the air inlet duct 2, located between the first filter screen 10 and the condenser assembly 13. The air humidity sensor is used to detect the humidity of the incoming air, and the air temperature sensor is used to detect the temperature of the incoming air. Both the air humidity sensor and the air temperature sensor are connected to a processor.

[0077] Differential pressure sensors are provided at both ends of the first filter screen 10 and the second filter screen 11. The differential pressure sensors are connected to the processor signal and are used to detect the air pressure difference at both ends of the first filter screen 10 and the second filter screen 11, thereby monitoring whether the first filter screen 10 and the second filter screen 11 are blocked.

[0078] In this embodiment, the drive motor 5 is started, and the drive motor 5 drives the fan blades 9 to rotate through the bushing 8, thereby causing air to flow. The air enters from the air inlet pipe 2 and passes through the grid 12, the first filter 10, the condenser assembly 13, the middle pipe 3, the second filter 11 in sequence, and finally flows out through the louver 39.

[0079] During this process, the humidity of the air entering the air inlet duct 2 is monitored by an air humidity sensor, and the temperature of the air entering the air inlet duct 2 is monitored by an air temperature sensor.

[0080] The actual air humidity value detected by the air humidity sensor is preset by the processor and recorded as R1;

[0081] The actual air temperature value detected by the preset air temperature sensor is denoted as T1;

[0082] The processor controls the rotation angle of the guide vane 17 based on the values ​​of T1 and R1, as follows:

[0083] S1: When T1 < 20℃, adjust the angle of the guide vane 17 according to the value of R1, as follows:

[0084] S11: When R1 < 60%, the angle of the guide vane 17 is controlled to be 15°-18° by the rotary motor 24, and the micro condenser 26 operates at low power at the same time.

[0085] S12: When 60%≤R1<80%, the angle of the guide vane 17 is controlled to be 22°-25° by the rotary motor 24, and the micro condenser 26 operates at medium power at the same time.

[0086] S13: When R1≥80%, the angle of the guide vane 17 is controlled to be 26°-28° by the rotary motor 24, and the micro condenser 26 operates at high power.

[0087] S2: When 20℃≤T1<30℃, adjust the angle of the guide vane 17 according to the value of R1, as follows:

[0088] S21: When R1 < 50%, the angle of the guide vane 17 is controlled to be 18°-20° by the rotary motor 24, and the micro condenser 26 operates at medium power at the same time.

[0089] S22: When 50%≤R1<70%, the angle of the guide vane 17 is controlled to be 24°-27° by the rotary motor 24, and the micro condenser 26 operates at high power at the same time.

[0090] S23: When R1≥70%, the angle of the guide vane 17 is controlled to be 28°-30° by the rotary motor 24, and the micro condenser 26 operates at ultra-high power.

[0091] S3: When T1≥30℃, under any humidity conditions, the angle of the guide vane 17 is dynamically adjusted according to the following formula: α=0.4*T1+0.3*R1; where α is the angle to be adjusted for the guide vane 17, and the micro condenser 26 operates at ultra-high power.

[0092] The purpose of adjusting the angle of the guide vane 17 is to increase the airflow resistance, thereby increasing the time for air to pass through the condenser assembly 13, and thus improving the air condensation effect.

[0093] Water vapor in the air condenses on the guide vane 17 and collects in the collection tank 27 under the action of gravity. After passing through the filter through the pipeline, it enters the water storage box.

[0094] The processor presets the warning value of the differential pressure sensor to N1 and the actual value of the differential pressure sensor to N2.

[0095] When N2 < N1, the processor determines that the first filter screen 10 or the second filter screen 11 is not blocked;

[0096] When N2 ≥ N1, the processor determines that either the first filter 10 or the second filter 11 is blocked;

[0097] When the first filter screen 10 or the second filter screen 11 becomes clogged, the corresponding drive motor 35 is started to run. The micro pump draws water from the water storage box into the scraper 32 and flows out through the water outlet 33. The wiping cloth on the scraper 32 absorbs water and cleans the first filter screen 10 or the second filter screen 11 during the movement of the scraper 32.

[0098] Because the first filter screen 10 and the second filter screen 11 are hydrophobic, the water stains on the first filter screen 10 and the second filter screen 11 flow into the collection tank 40 under the action of gravity, and after being filtered by the filter, they re-enter the water storage box to participate in subsequent cleaning.
