Description

Technical Field

[0001] This invention relates to the field of fan coil unit technology, specifically to a fan coil unit air conditioning fresh air purification and humidification device. Background Technology

[0002] Fan coil units are terminal equipment in air conditioning systems, generally consisting of a fan and a heat exchanger. The fan drives outside air to flow through the heat exchanger, where it exchanges heat before being discharged into the room to regulate the indoor air temperature.

[0003] A fan coil unit disclosed in patent CN114294711A introduces external air through an exhaust duct and shapes the inner casing to create two low-pressure or even vacuum zones in the converging air duct. This induces a large amount of external air to flow into the converging air duct from the inlet end, and after heat exchange, it is discharged. However, after the fan coil unit draws in the gas, it needs to perform temperature control and transportation processing. Because the gas contains particulate matter, the filter screen inside the fan coil unit needs to be disassembled and cleaned periodically. The high installation position of the fan coil unit makes the filter screen disassembly work complicated. Summary of the Invention

[0048] A blocking plate is installed on the outside of the inclined tube.

[0049] This invention provides a fresh air purification and humidification device for fan coil air conditioners. It has the following beneficial effects:

[0050] 1. This fan coil unit air conditioning fresh air purification and humidification device uses an interception mechanism and replaceable components to intercept particulate matter in the air intake duct. Existing fan coil units draw in air, then control the temperature and transport the drawn air. Because the air contains particulate matter, the filter inside the fan coil unit needs to be disassembled and cleaned periodically. However, the high installation position of the fan coil unit makes filter removal complex. By setting up an interception mechanism and replaceable components, multiple first rings and first arc-shaped plates are incorporated, allowing for easy control of angle and height. The first arc-shaped plates are designed with a thicker center and thinner edges, and first through holes are opened on the arc surface of the first arc plate. This facilitates the interception of particulate matter in the air, making it more difficult for particulate matter to enter the first through holes, reducing the occurrence of blockage, and allowing particulate matter to slide down the arc surface onto the tray. The above problems are solved by installing a replaceable component with a filtering and interception function at the front of the unit.

[0051] 2. This fan coil air conditioner's fresh air purification and humidification device uses an interception mechanism and a rotating assembly to intercept and purify the air entering the intake duct. A second arc-shaped plate made of double-layer activated carbon is installed in the rotating assembly, with a third through-hole in the second arc-shaped plate. This facilitates the adsorption of impurities and odors in the intake air, thus performing a simple purification process and reducing odors and impurities entering the unit. Consequently, it also reduces odors and impurities in the air exiting through the exhaust duct.

[0052] 3. This fan coil air conditioner fresh air purification and humidification device, through its humidification mechanism, periodically collects and tests the hardness of the water stored in the installation box. A storage tank, easily adjustable in height, is incorporated into the humidification mechanism. A fixed amount of water is periodically added from the installation box into the storage tank, and workers manually test the water hardness in the tank to determine if it exceeds the standard. This allows for timely adjustments to the equipment, preventing increased scale buildup inside the unit due to excessive water hardness, and thus avoiding blockages in the unit or air ducts.

[0053] 4. This fan coil air conditioner's fresh air purification and humidification device humidifies the air in the outlet duct by setting up a humidification mechanism. By opening a second channel at the bottom of each outlet duct and using inclined pipes to spray water and humidify the air, it is easy to adjust the opening time of different spray pipes according to the humidification requirements of different rooms, thereby controlling the amount of water added to different outlet ducts. Furthermore, the inclined direction of the pipes aligns with the direction of air movement, thus reducing the amount of water entering the unit and minimizing scale buildup inside.

[0064] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0065] like Figures 1-9 As shown, the present invention provides a technical solution: including a body 1;

[0066] Water receiving tray 11 is installed at the bottom of the body 1;

[0067] Side plate 2, which is installed on the outside of the water receiving tray 11;

[0068] Installation box 4 is installed at the bottom of water receiving tray 11;

[0069] The interception mechanism 3 is installed on the outside of the side panel 2. The interception mechanism 3 includes a replacement component 304 and a rotating component 307. The replacement component 304 and the rotating component 307 are used to intercept and purify particulate matter in the fresh air.

[0070] Humidification mechanism 5 is located outside the mounting box 4. Humidification mechanism 5 includes a sixth push rod 506. A first fixing ring 507 is installed at the telescopic end of the sixth push rod 506. A telescopic pipe 505 is installed inside the first fixing ring 507. An inclined pipe 509 is installed at the top of the telescopic pipe 505. The sixth push rod 506 is used to control the lifting and lowering of the inclined pipe 509. The sixth push rod 506 is set as an electric push rod.

[0071] The impeller 6 is located on the outside of the body 1;

[0072] Valve 7 is installed on the outside of the wind turbine 6;

[0073] Air inlet duct 8 is connected to valve 7, and a first channel 12 is opened at the bottom of air inlet duct 8;

[0074] Outer box 9, which is installed at the bottom of air inlet duct 8;

[0075] Air outlet duct 10 is installed on the outside of the body 1, and a second channel 13 is opened inside the air outlet duct 10.

[0076] Before using the equipment, adjust the humidification mechanism 5 and the interception mechanism 3 to intercept and purify the fresh air entering the air inlet duct 8, and adjust the position of the humidification duct. Then turn on the unit 1, and the air enters the unit 1 through the air inlet duct 8. After the unit 1 performs temperature control on the air, the air moves outward through the air outlet duct 10, and the humidification mechanism 5 begins to humidify the air. During operation, periodically turn on the humidification mechanism 5 and perform random checks on the water quality used for humidification.

[0077] Interception mechanism 3 also includes:

[0078] Motor housing 301, the motor housing 301 contains a motor;

[0079] Fixed shaft 302 is connected to the output end of the motor;

[0080] The first push rod 303 has its fixed end installed outside the motor housing 301, and its telescopic end engaged with the replacement component 304. The first push rod 303 is configured as an electric push rod.

[0081] The second push rod 305 has its fixed end installed outside the fixed shaft 302, and the second push rod 305 is configured as an electric push rod.

[0082] The third push rod 306 is connected to the telescopic end of the second push rod 305. The telescopic end of the third push rod 306 is connected to the rotating assembly 307. The third push rod 306 is configured as an electric push rod.

[0083] Magnetic block 308 is installed outside the fixed shaft 302. There are two magnetic blocks 308, which are arranged symmetrically.

[0084] Before using the equipment, activate the third push rod 306. The third push rod 306 will drive the rotating component 307 into the outer box 9. Then, manually insert the outer panel into the outer box 9 to seal it. Activate the motor in the motor housing 301. The motor will drive the fixed shaft 302, the second push rod 305, the third push rod 306, and the rotating component 307 to rotate. Simultaneously, adjust and replace component 304 to process the incoming air.

[0085] Replacement of component 304 includes:

[0086] The center plate 3041 is engaged with the telescopic end of the first push rod 303, and the center plate 3041 is made of magnetic material.

[0087] The fourth push rod 3042 has its fixed end installed on the outside of the center plate 3041. There are three fourth push rods 3042, and the fourth push rod 3042 is set as an electric push rod.

[0088] The first ring 3043 is connected to the telescopic end of the fourth push rod 3042;

[0089] Tray 3044 is mounted on the outside of the first ring 3043;

[0090] The first arc-shaped plate 3045 is installed inside the first ring 3043. The first arc-shaped plate 3045 has a first through hole inside and is configured to be thick in the middle and thin at the edges.

[0091] Before using the equipment, the center plate 3041 is magnetically fixed to the outside of the magnetic block 308. At this time, the first push rod 303 is not activated and does not contact the center plate 3041. When the motor in the motor housing 301 is turned on, the motor controls the fixed shaft 302 to rotate, and the fixed shaft 302 drives the center plate 3041 to rotate, thus selecting the first ring 3043 located at the top.

[0092] Then, the first push rod 303 is activated, and it gradually engages with the interior of the center plate 3041, pushing it away from the magnet 308. The center plate 3041 gradually separates from the magnet 308. The fourth push rod 3042 is then activated, causing the first ring 3043, tray 3044, and first arc-shaped plate 3045 to move upwards. These components gradually enter the first channel 12, with the tray 3044 blocking the opening of the first channel 12, and the first ring 3043 contacting the inner wall of the air inlet duct 8.

[0093] As gas enters the air inlet duct 8, particulate matter is intercepted outside the first arc-shaped plate 3045. The gas continues to move through the first through hole and enters the body 1. Because the first arc-shaped plate 3045 is designed with a thicker center and thinner edges, and the first through hole is opened in the arc-shaped first arc-shaped plate 3045, the intercepted particulate matter can easily slide down along the arc surface into the tray 3044, thereby reducing the amount of particulate matter entering the body 1.

[0094] When it is necessary to clean the first arc plate 3045, the first ring 3043, and the tray 3044, the angle of the center plate 3041 is adjusted by the motor so that the first arc plate 3045 to be cleaned is in a vertically downward direction. Then, the corresponding fourth push rod 3042 is activated. The fourth push rod 3042 drives the first ring 3043, the tray 3044, and the first arc plate 3045 to move downward. At this time, the worker can manually clean the first arc plate 3045, the first ring 3043, and the tray 3044.

[0095] By setting up an interception mechanism 3 and a replacement component 304, particulate matter is intercepted in the air intake duct 8. Existing fan coil units draw in gas, then perform temperature control and transportation processing. Because the gas contains particulate matter, the filter screen inside the fan coil unit needs to be disassembled and cleaned periodically. However, the high installation position of the fan coil unit makes filter screen disassembly complex. By setting up the interception mechanism 3 and the replacement component 304, multiple first rings 3043 and a first arc-shaped plate 3045 are incorporated, allowing for easy control of angle and height. The first arc-shaped plate 3045 is designed with a thicker center and thinner edges, and a first through-hole is opened on its arc surface. This facilitates the interception of particulate matter in the gas, making it more difficult for particulate matter to enter the first through-hole, reducing the occurrence of blockage, and allowing particulate matter to slide down the arc surface onto the tray 3044. The above problems are solved by setting up a replacement component 304 with a filtering and interception function at the front of the unit 1.

[0096] Rotating assembly 307 includes:

[0097] The second ring 3071 is connected to the telescopic end of the third push rod 306, and a second through hole is provided inside the second ring 3071;

[0098] The second arc plate 3072 is installed inside the second ring 3071. There are two second arc plates 3072, which are symmetrically arranged. The second arc plate 3072 is made of activated carbon material, and a third through hole is opened inside the second arc plate 3072.

[0099] The fifth push rod 3073 is installed inside the second ring 3071 and is configured as an electric push rod.

[0100] The center cylinder 3074 is connected to the telescopic end of the fifth push rod 3073;

[0101] There are two adjusting rods 3075, both of which are installed on the outside of the central cylinder 3074;

[0102] Scraper 3076 is connected to adjusting rod 3075 and contacts second arc plate 3072. Scraper bar is installed on the outside of scraper 3076.

[0103] As the motor is turned on, it drives the second push rod 305, the third push rod 306, and the second ring 3071 to rotate. The second ring 3071 drives the two second arc-shaped plates 3072 to rotate. The two second arc-shaped plates 3072, which are made of activated carbon, begin to adsorb impurities and odors in the gas. The fifth push rod 3073 is turned on to reciprocating motion mode. The fifth push rod 3073 drives the central cylinder 3074, the adjusting rod 3075, the scraper 3076, and the scraper rod to reciprocate. The scraper 3076 repeatedly hits the second ring 3071 to promote the unobstructed flow of the second through hole. The scraper rod repeatedly contacts the third through hole to promote the unobstructed flow of the third through hole.

[0104] By setting up the interception mechanism 3 and the rotating assembly 307, the gas entering the air intake duct 8 is intercepted and purified. By setting a second arc-shaped plate 3072 made of double-layer activated carbon material in the rotating assembly 307, and opening a third through hole in the second arc-shaped plate 3072, it is easy to adsorb impurities and odors in the intake air, thereby performing simple purification treatment on the intake air, reducing the odors and impurities entering the machine body 1, and thus reducing the odors and impurities in the gas moving outward through the air outlet duct 10.

[0105] Humidification unit 5 also includes:

[0106] Water inlet pipe 501 is installed at the bottom of mounting box 4. Water inlet pipe 501 is connected to an external water tank. Electric valve 7 is installed in water inlet pipe 501.

[0107] Water outlet pipe 502 is installed at the bottom of mounting box 4, and an electric valve 7 is installed in water outlet pipe 502;

[0108] Mounting plate 510 is installed at the bottom of mounting box 4, and there are two mounting plates 510.

[0109] The seventh push rod 511 is installed at the bottom of the mounting plate 510 and is configured as an electric push rod.

[0110] The second fixing ring 512 is connected to the telescopic end of the seventh push rod 511;

[0111] Storage cylinder 513 is installed inside the second fixing ring 512;

[0112] When using the equipment, adjust the electric valve 7 in the water outlet pipe 502 to allow a small amount of water from the installation box 4 to flow into the storage cylinder 513 through the water outlet pipe 502. Then, activate the seventh push rod 511. The seventh push rod 511 will cause the second fixing ring 512 and the storage cylinder 513 to move downwards. The worker can then use a handheld water hardness detector to test the water hardness. If the water hardness exceeds the standard, the worker needs to adjust the water inlet or repair the pipes connected to the installation box 4, the water inlet pipe 501, and the water outlet pipe 502. This will reduce the risk of excessive scale buildup inside the machine body 1 and the air outlet pipe 10 due to untimely treatment of excessive water hardness, and may even cause blockage inside the machine body 1.

[0113] The humidification mechanism 5 is used to periodically collect and test the hardness of the water in the installation box 4. A storage cylinder 513, which is easily raised and lowered, is installed in the humidification mechanism 5. A fixed amount of water from the installation box 4 is periodically fed into the storage cylinder 513. Workers manually test the hardness of the water in the storage cylinder 513 to determine if it exceeds the standard. This allows for timely adjustments to the equipment, preventing increased scale buildup in the machine body 1 due to excessive water hardness, and thus avoiding blockages in the machine body 1 or the air outlet duct 10.

[0114] The nozzle 504 is installed on the outside of the mounting box 4. Multiple nozzles 504 are provided. The telescopic pipe 505 is connected to the nozzle 504. An electric valve 7 is installed inside the nozzle 504.

[0115] Arc-shaped support plate 503 is installed on the outside of the mounting box 4 and contacts the nozzle 504. The sixth push rod 506 is installed on the top of the arc-shaped support plate 503.

[0116] The blocking plate 508 is installed on the outside of the inclined tube 509.

[0117] When the sixth push rod 506 is activated, it causes the first fixing ring 507 to move upward. The first fixing ring 507 stretches the telescopic pipe 505 upward, which in turn causes the blocking plate 508 and the inclined pipe 509 to move upward. The blocking plate 508 and the inclined pipe 509 gradually enter the second channel 13. The blocking plate 508 gradually blocks the opening of the second channel 13. As the spray pipe 504 is opened, water enters the telescopic pipe 505 through the spray pipe 504, then enters the inclined pipe 509 through the telescopic pipe 505, and then enters the air outlet pipe 10 at an angle through the inclined pipe 509, where it combines with the gas in the air outlet pipe 10, thereby humidifying the gas.

[0118] The humidification mechanism 5 is used to humidify the gas in the air outlet duct 10. By opening a second channel 13 at the bottom of each air outlet duct 10, water is sprayed onto the gas using inclined pipes 509. This allows for adjustment of the opening time of different spray pipes 504 according to the humidification requirements of different rooms, thereby controlling the amount of water added to different air outlet ducts 10. Furthermore, the inclined direction of the inclined pipes 509 is in line with the direction of gas movement, thereby reducing the amount of water entering the unit 1 and reducing the formation of scale inside the unit 1.

[0119] Working principle: Before using the equipment, adjust the humidification mechanism 5 and the interception mechanism 3 to intercept and purify the fresh air entering the air inlet duct 8, and adjust the position of the humidification duct.

[0120] Before using the equipment, activate the third push rod 306. The third push rod 306 will drive the rotating component 307 into the outer box 9. Then, manually insert the outer panel into the outer box 9 to seal it. Activate the motor in the motor housing 301. The motor will drive the fixed shaft 302, the second push rod 305, the third push rod 306, and the rotating component 307 to rotate. Simultaneously, adjust and replace component 304 to process the incoming air.

[0121] As the motor is turned on, it drives the second push rod 305, the third push rod 306, and the second ring 3071 to rotate. The second ring 3071 drives the two second arc-shaped plates 3072 to rotate. The two second arc-shaped plates 3072, which are made of activated carbon, begin to adsorb impurities and odors in the gas. The fifth push rod 3073 is turned on to reciprocating motion mode. The fifth push rod 3073 drives the central cylinder 3074, the adjusting rod 3075, the scraper 3076, and the scraper rod to reciprocate. The scraper 3076 repeatedly hits the second ring 3071 to promote the unobstructed flow of the second through hole. The scraper rod repeatedly contacts the third through hole to promote the unobstructed flow of the third through hole.

[0122] Before using the equipment, the center plate 3041 is magnetically fixed to the outside of the magnetic block 308. At this time, the first push rod 303 is not activated and does not contact the center plate 3041. When the motor in the motor housing 301 is turned on, the motor controls the fixed shaft 302 to rotate, and the fixed shaft 302 drives the center plate 3041 to rotate, thus selecting the first ring 3043 located at the top.

[0123] Then, the first push rod 303 is activated, and it gradually engages with the interior of the center plate 3041, pushing it away from the magnet 308. The center plate 3041 gradually separates from the magnet 308. The fourth push rod 3042 is then activated, causing the first ring 3043, tray 3044, and first arc-shaped plate 3045 to move upwards. These components gradually enter the first channel 12, with the tray 3044 blocking the opening of the first channel 12, and the first ring 3043 contacting the inner wall of the air inlet duct 8.

[0124] As gas enters the air inlet duct 8, particulate matter is intercepted outside the first arc-shaped plate 3045. The gas continues to move through the first through hole and enters the body 1. Because the first arc-shaped plate 3045 is designed with a thicker center and thinner edges, and the first through hole is opened in the arc-shaped first arc-shaped plate 3045, the intercepted particulate matter can easily slide down along the arc surface into the tray 3044, thereby reducing the amount of particulate matter entering the body 1.

[0125] Then, the unit 1 is turned on, and the gas enters the unit 1 through the air inlet pipe 8. After the unit 1 performs temperature control on the gas, the gas moves outward through the air outlet pipe 10, and the humidification mechanism 5 begins to humidify the gas.

[0126] When the sixth push rod 506 is activated, it causes the first fixing ring 507 to move upward. The first fixing ring 507 stretches the telescopic pipe 505 upward, which in turn causes the blocking plate 508 and the inclined pipe 509 to move upward. The blocking plate 508 and the inclined pipe 509 gradually enter the second channel 13. The blocking plate 508 gradually blocks the opening of the second channel 13. As the spray pipe 504 is opened, water enters the telescopic pipe 505 through the spray pipe 504, then enters the inclined pipe 509 through the telescopic pipe 505, and then enters the air outlet pipe 10 at an angle through the inclined pipe 509, where it combines with the gas in the air outlet pipe 10, thereby humidifying the gas.

[0127] During operation, the humidification unit 5 is periodically activated to sample and test the water quality. The electric valve 7 in the outlet pipe 502 is adjusted to allow a small amount of water from the installation box 4 to flow into the storage box through the outlet pipe 502. Then, the seventh push rod 511 is activated, causing the second fixing ring 512 and the storage cylinder 513 to move downwards. A worker then uses a handheld water hardness tester to check the water hardness. If the water hardness exceeds the standard, the worker needs to adjust the water inlet or repair the pipes connecting the installation box 4, the inlet pipe 501, and the outlet pipe 502. This reduces the risk of excessive scale buildup inside the unit 1 and the air outlet pipe 10 due to delayed treatment of excessive water hardness, and can even lead to blockages inside the unit 1.
