Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving air conditioner cooling fans, and particularly to an energy-saving air conditioner cooling fan with a protection function. Background Art

[0002] The energy-saving air conditioner cooling fan is an efficient device that realizes cooling through the principle of evaporative cooling. Its core function is to convert the external high-temperature air into cool air flow through the heat exchange between the water curtain or ice curtain and the air, and at the same time has the characteristic of low energy consumption (the power consumption per hour is usually less than 1 kWh) 15. Such devices are widely used in large-space scenarios such as factories and workshops, and have the advantages of rapid cooling (4 - 15 °C), improved air quality, energy conservation and environmental protection. Although the energy-saving air conditioner cooling fan performs excellently in terms of energy consumption and cooling efficiency, there are still the following significant problems in its dust-proof and moisture-proof designs: I. Insufficient dust-proof ability: The cooling fan relies on the filter screen to block dust. However, after long-term operation, the filter screen is easily blocked by dust, hair, etc., resulting in a decrease in air volume or even shutdown. If the filter screen is not cleaned regularly, the cooling fan will have an odor due to dust accumulation, and it needs to be disassembled and cleaned frequently, resulting in a high maintenance cost.

[0003] II. Weak moisture-proof design: The interior of the device may be affected by high environmental humidity and get damp, leading to motor short circuits or rust. If the cooling fan does not adopt a waterproof or sealed design, the failure rate will increase significantly.

[0004] Therefore, it is necessary to design an energy-saving air conditioner cooling fan with a protection function to improve the dust-proof and moisture-proof capabilities of the energy-saving air conditioner cooling fan. Summary of the Invention

[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] Please refer to Figure 1-7 , the present invention provides a technical solution: an energy-saving air-conditioning cooling fan with a protection function, including a housing 1.

Four corners at both ends of the first motor housing 6 along the length direction are fixedly connected with first support rods 7, and the ends of the first support rods 7 far away from the first motor housing 6 are fixedly connected to the pipe wall of the middle section pipe 3; The output shaft of the first driving motor 5 is fixedly connected with a bush 8, and a plurality of fan blades 9 are detachably connected to the outer circumferential wall of the bush 8. The plurality of fan blades 9 are evenly distributed in a circle with the center of the bush 8 as the center, and the fan blades 9 are driven to rotate by the first driving motor 5.

[0022] A first filter screen 10 is arranged at one end of the air inlet pipe 2 far away from the middle section pipe 3, and a second filter screen 11 is arranged at one end of the air outlet pipe 4 far away from the middle section pipe 3; Both the first filter screen 10 and the second filter screen 11 adopt nano-hydrophobic and dust-proof filter screens, which are hydrophobic and have a mesh diameter of 1 mm; A protective coating made of titanium dioxide is coated on both the first filter screen 10 and the second filter screen 11. Under the action of light, titanium dioxide can generate highly active substances such as hydroxyl radicals and superoxide radicals, which can decompose organic pollutants, bacteria, etc. adsorbed on the surface of the filter screen, thereby improving the self-cleaning effect of the filter screen.

[0023] A grid screen 12 is arranged 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 10 mm.

[0024] Such as Figure 3 , a condensation component 13 is arranged on the side of the first filter screen 10 close to the middle section pipe 3. The condensation component 13 includes a central cylinder 14. The central cylinder 14 is open towards 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 is integrally provided with the central cylinder 14. One end of the connecting plate 15 close to the first filter screen 10 along the axis of the central cylinder 14 penetrates through the central cylinder 14. Fixed rods 16 are fixedly connected at the four corners of the upper and lower surfaces of the connecting plate 15. The fixed rods 16 are fixedly connected to the wall of the air inlet pipe 2.

[0025] A number of guide vanes 17 are hinged on the circumferential outer wall of the central cylinder 14. The number of guide vanes 17 is spiral, and the number of guide vanes 17 is evenly distributed in a circle with the axis of the central cylinder 14 as the center; Such as Figure 4 , a connecting shaft 18 is fixedly connected to the root of the guide vane 17. Both ends of the connecting shaft 18 are rotatably connected with connecting blocks 19. The connecting blocks 19 are fixedly connected to the outer wall of the central cylinder 14.

[0026] One end of the connecting shaft 18 close to the middle section pipe 3 along the axis penetrates through the connecting block 19 and is fixedly connected with a first gear 20. A sleeve 21 is nested at one end of the central cylinder 14 close to the middle section pipe 3. The sleeve 21 is rotatably connected with the central cylinder 14. An external gear ring 22 is sleeved on the side of the outer wall of the sleeve 21 away from the central cylinder. The external gear ring 22 is fixedly connected with the sleeve 21. An internal gear ring 23 is fixedly connected to the inner wall of the sleeve 21; The connecting plate 15 is fixedly connected with an angle motor 24 located in the center tube 14, and the output end of the angle motor 24 is fixedly connected with a gear 25, which meshes with the gear of the inner gear ring 23, and the gear 1 20 meshes with the gear of the outer gear ring 22, so that the angle motor 24 drives the gear 1 20 to rotate, thereby driving the guide blade 17 to rotate with the connecting shaft 18 as a reference, so as to change the resistance of air flow by adjusting the angle of the guide blade 17.

[0027] Specifically, the angle motor 24 can only adjust the guide vane 17 in one direction, and the adjustable angle threshold is 0°-30°.

[0028] A condensation channel is provided in the guide vane 17, and the condensation channel is an "S"-shaped cavity channel. The input port of the condensation channel is provided at one end of the connecting shaft 18 close to the first filter screen 10, and the output port of the condensation channel is provided at one end of the gear 1 20 close to the middle section pipe 3; A micro condenser 26 is fixedly connected to the side of the connecting plate 15 away from the corner motor 24, and an input branch pipe is fixedly connected to the input port of the condensation channel. The input branch pipe runs through the central tube 14, and the input end of the input branch pipe is fixedly connected to the input main pipe through a multi-way valve, and the input main pipe is connected to the output end of the micro condenser 26; The output port of the condensation channel is fixedly connected with an output branch pipe, and the input end of the output branch pipe is fixedly connected with an output main pipe through a multi-way valve. The output main pipe is connected to the input end of the micro condenser 26, so as to realize the refrigeration effect on the guide vane 17 through the micro condenser 26.

[0029] like Figure 5 A step 42 is formed on one end of the air inlet pipe 2 near the middle pipe 3, and one side of the guide vane 17 along the axial direction of the central tube 14 is close to the step 42; When the guide vane 17 is adjusted, the diameter of the air acted upon by the guide vane 17 changes. Therefore, the minimum diameter of the air acted upon by the guide vane 17 is larger than the inner diameter of the step 42 , so that the side of the step 42 blocks the air and prevents the air from directly entering the middle tube 3 without passing through the guide vane 17 .

[0030] A collecting groove 27 is provided on the wall of the air inlet pipe 2 at one end thereof corresponding to the guide vane 17 and away from the middle pipe 3 . The collecting groove 27 is a semicircular ring structure and is used to collect water condensed from the guide vane 17 .

[0031] A water storage box is fixedly connected to the outer wall of the air inlet pipe 2, and a water outlet 28 is provided at the bottom of the collecting tank 27. The water outlet 28 is connected to the water storage box through a pipe. A filter is provided 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 an existing conventional technology and is used to purify and filter water.

[0032] A liquid level sensor is arranged in the water storage box for detecting the water level in the water storage box. The water storage box is fixedly connected with a solenoid valve. When the water level in the water storage box exceeds the upper limit of the water level of the liquid level sensor, it is automatically discharged through the solenoid valve.

[0033] Both the first filter screen 10 and the second filter screen 11 are annular filter screens. Circular holes 29 are formed at the centers of the first filter screen 10 and the second filter screen 11. A cleaning assembly 30 is rotatably connected in the circular holes 29.

[0034] As Figure 6 , the cleaning assembly 30 includes a rotating shaft 31. The rotating shaft 31 is located in the circular hole 29 and is rotatably connected with the circular hole 29. Both ends of the rotating shaft 31 in the axial direction are fixedly connected with two scraping plates 32. The two scraping plates 32 are arranged oppositely. A wiping cloth is wrapped on one side of the two scraping plates 32 close to the first filter screen 10. The wiping cloth is made of ultra-fine fibers and has high water absorption and anti-wear effects; As Figure 7 , a number of water outlet holes 33 are formed at the positions of the scraping plates 32 wrapped by the wiping cloth. The number of water outlet holes 33 is arranged in an array. A water inlet hole 34 is formed at the position of the scraping plate 32 close to the rotating shaft 31. A water inlet channel is formed in the scraping plate 32. The water inlet channel communicates the water inlet hole 34 and the water outlet holes 33; Water enters through the water inlet hole 34 and flows out through the water outlet holes 33, and then is absorbed by the wiping cloth to clean the first filter screen 10.

[0035] A second driving motor 35 is fixedly connected to one side of the connecting plate 15 close to the first filter screen 10. The output shaft of the second driving motor 35 is fixedly connected with the rotating shaft 31. The rotating shaft 31 is driven to rotate by the second driving motor 35, and then the scraping plates 32 rotate circumferentially around the rotating shaft 31, so as to clean the first filter screen 10.

[0036] A hydraulic slip ring 36 is sleeved on the rotating shaft 31. The hydraulic slip ring is a conventional existing technology. As a transfer part, the hydraulic slip ring 36 can conduct liquid transmission for the mechanism on a 360° rotating object. The sliding ring of the hydraulic slip ring 36 is sleeved on the rotating shaft 31 and is fixedly connected with the rotating shaft 31. The fixed ring of the hydraulic slip ring 36 is fixedly connected with a bracket 43. One end of the bracket 43 far from the hydraulic slip ring 36 is fixedly connected with the inner wall of the air inlet pipe 2; The output end of the hydraulic slip ring 36 on the sliding ring is connected to the water inlet hole 34 through a pipeline. The input end of the hydraulic slip ring 36 on the fixed ring is connected with a micro pump through a pipeline penetrating 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 pipeline of the micro pump is connected to the water storage box, so as to supply water to the water inlet hole 34 through the micro pump and the hydraulic slip ring 36.

[0037] The cleaning components 30 on the first filter screen 10 and the second filter screen 11 have the same structure. The difference is that a motor housing two 37 is sleeved outside the drive motor two 35 of the cleaning component 30 on the second filter screen 11. At the four corners of the motor housing two 37 along the length direction, support rods two 38 are fixedly connected. One end of the support rod two 38 away from the motor housing two 37 is fixedly connected to the wall of the air outlet pipe 4.

[0038] The hydraulic slip ring 36 of the cleaning component 30 on the second filter screen 11 is located at the input end on the fixed ring. The pipeline passes through the air outlet pipe 4 and is connected to the micro pump through a multi-way valve.

[0039] On the side of the second filter screen 11 away from the middle section pipe 3, a shutter 39 is fixedly connected. The outer frame of the shutter 39 is circular, so that the shutter 39 is adapted to the air outlet pipe 4.

[0040] On the walls of the air outlet pipe 4 and the air inlet pipe 2, collection grooves two 40 are respectively opened corresponding to the two ends of the second filter screen 11 and the first filter screen 10. The collection groove one 27 is a semi-circular ring structure, which is used to collect the water stains flowing down from the first filter screen 10 or the second filter screen 11; At the bottom of the two collection grooves two 40, water outlets two 41 are opened. The water outlets two 41 are connected to the filter through a multi-way valve pipeline.

[0041] On the wall of the air inlet pipe 2 between the first filter screen 10 and the condensation component 13, an air humidity sensor and an air temperature sensor are fixedly connected. 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 signal-connected to a processor.

[0042] Differential pressure sensors are arranged at both ends of the first filter screen 10 and the second filter screen 11. The differential pressure sensors are signal-connected to the processor. The differential pressure sensors are used to detect the air pressure difference at both ends of the first filter screen 10 and the second filter screen 11, so as to monitor whether the first filter screen 10 and the second filter screen 11 are blocked.

[0043] In this embodiment, the drive motor one 5 is started. The drive motor one 5 drives the fan blades 9 to rotate through the shaft sleeve 8, so that the air flows. The air enters from the air inlet pipe 2 and passes through the grid 12, the first filter screen 10, the condensation component 13, the middle section pipe 3, the second filter screen 11 in turn, and finally flows out through the shutter 39.

[0044] During this process, the air humidity entering the air inlet pipe 2 is monitored through the air humidity sensor, and at the same time, the air temperature entering the air inlet pipe 2 is monitored through the air temperature sensor; The actual air humidity value detected by the air humidity sensor is preset by the processor, denoted as R1; The actual air temperature value detected by the preset air temperature sensor is denoted as T1; The processor controls the rotation angle of the guide vane 17 according to the values of T1 and R1, as follows: S1: When T1 < 20 °C, the angle of the guide vane 17 is adjusted according to the value of R1, as follows: S11: When R1 < 60%, the angle of the guide vane 17 is controlled by the rotation angle motor 24 to be 15° - 18°, and at the same time, the micro condenser 26 operates at a low power; S12: When 60% ≤ R1 < 80%, the angle of the guide vane 17 is controlled by the rotation angle motor 24 to be 22° - 25°, and at the same time, the micro condenser 26 operates at a medium power; S13: When R1 ≥ 80%, the angle of the guide vane 17 is controlled by the rotation angle motor 24 to be 26° - 28°, and at the same time, the micro condenser 26 operates at a high power.

[0045] S2: When 20 °C ≤ T1 < 30 °C, the angle of the guide vane 17 is adjusted according to the value of R1, as follows: S21: When R1 < 50%, the angle of the guide vane 17 is controlled by the rotation angle motor 24 to be 18° - 20°, and at the same time, the micro condenser 26 operates at a medium power; S22: When 50% ≤ R1 < 70%, the angle of the guide vane 17 is controlled by the rotation angle motor 24 to be 24° - 27°, and at the same time, the micro condenser 26 operates at a high power; S23: When R1 ≥ 70%, the angle of the guide vane 17 is controlled by the rotation angle motor 24 to be 28° - 30°, and at the same time, the micro condenser 26 operates at an ultra - high power.

[0046] S3: When T1 ≥ 30 °C, under any humidity condition, 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 at the same time, the micro condenser 26 operates at an ultra - high power.

[0047] The purpose of the above angle adjustment of the guide vane 17 is to increase the air flow resistance, so that the time for the air to pass through the condensation component 13 increases, thereby improving the air condensation effect.

[0048] The water vapor in the air condenses on the guide vane 17 and converges into the first collection tank 27 under the action of gravity, and then enters the water storage box through the pipeline after being filtered by the filter.

[0049] The processor presets the warning value of the differential pressure sensor as N1 and the actual value of the differential pressure sensor as N2; When N2 < N1, the processor determines that the first filter screen 10 or the second filter screen 11 is not blocked; When N2 ≥ N1, the processor determines that the first filter screen 10 or the second filter screen 11 is blocked; When the first filter screen 10 or the second filter screen 11 is blocked, the corresponding driving motor two 35 is started to operate, the micro pump pumps the water in the water storage box into the squeegee 32, and flows out through the water outlet hole 33, so that the cleaning cloth on the squeegee 32 absorbs water, and the first filter screen 10 or the second filter screen 11 is cleaned during the movement of the squeegee 32; Since 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 second 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.
