Description

Technical Field

[0001] This utility model belongs to the field of fan coil unit technology, and specifically relates to a fan coil unit with dust filtration function. Background Technology

[0002] Fan coil units, also known as fan coil units, are one of the terminal devices in air conditioning systems, consisting of a small fan, motor, coil, and air heat exchanger. When chilled water or hot water flows through the coil, it exchanges heat with the air outside the coil, thereby cooling, dehumidifying, or heating the air to regulate indoor air parameters. They are commonly used terminal devices for cooling and heating.

[0003] Chinese patent with announcement number "CN210601901U" discloses a fan coil unit with dust filtration function, including a fan coil unit body, an air outlet on the front of the fan coil unit body, an air inlet on the back of the fan coil unit body, and a conical tube inside the fan coil unit body, with the back end of the conical tube communicating with the air inlet.

[0004] However, this device still has some shortcomings. When using the fan coil unit, it can only push the rectangular horizontal plate open by wind force. If the spring or other structure deviates at an angle or gets stuck, the rectangular horizontal plate cannot be pushed open normally. At the same time, if the wind force is insufficient, the seal of the rectangular horizontal plate cannot allow the wind force to flow normally, thus making the fan coil unit unable to be used normally. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a fan coil unit with dust filtration function to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A fan coil unit with dust filtration function includes a fan coil unit body, a top cover snapped onto the top of the fan coil unit body, a ventilation opening on the front side of the fan coil unit body, a baffle fixedly connected to the inner wall of the ventilation opening, a strip-shaped opening at the top of the fan coil unit body communicating with the inner side of the ventilation opening, a dustproof plate inserted into the inner side of the strip-shaped opening, the bottom end of the dustproof plate snapped onto the inner side of the ventilation opening, a mounting plate threaded onto the inner wall of the fan coil unit body, a tapered tube fixedly connected to one side of the mounting plate, an air inlet on one side of the tapered tube communicating with the ventilation opening, and a protective plate installed on one side of the fan coil unit body.

[0009] As a preferred technical solution, a slot is provided at the top of the fan coil unit, and a matching block is fixedly connected to the bottom of the top cover. The block is fixedly connected to the four sides near the corner of the bottom of the top cover, and the bottom of the block is engaged with the inside of the slot. The top cover is engaged with the top of the fan coil unit through the slot and the block.

[0010] As a preferred technical solution, a sealing groove is provided at the top of the fan coil unit, and a sealing gasket that matches the sealing groove is fixedly connected to the bottom of the top cover. The sealing gasket covers the inner side of the sealing groove and is located on the inner side of the adjacent locking block.

[0011] As a preferred technical solution, a second sealing plate is slidably connected to one side of the tapered tube, and a groove matching the second sealing plate is opened on one side of the tapered tube. The second sealing plate is slidably connected to one side of the tapered tube through the groove. A rotating shaft is rotatably connected to the front side of the second sealing plate, and a screw is fixedly connected to the front side of the rotating shaft. A first screw hole matching the screw is opened on the front side of the fan coil body, and the screw is threaded into the inner side of the first screw hole.

[0012] As a preferred technical solution, a second screw hole is provided on one side of the mounting plate. The second screw hole extends into the interior of the fan coil unit. A bolt is threaded into the inner side of the second screw hole. The bolt is threaded into the interior of the fan coil unit.

[0013] As a preferred technical solution, a through-hole is provided on the front side of the fan coil unit, which is connected to the inside of the fan coil unit. A transparent glass is fixedly connected to the inside of the through-hole, and the transparent glass covers the inside of the through-hole.

[0014] In summary, the present invention has the following main advantages:

[0015] Firstly, during use, the opening of the ventilation opening facilitates airflow, allowing air to be delivered to the fan coil unit. The presence of the baffle effectively blocks and protects the inside of the ventilation opening, while also allowing the airflow to enter the air inlet in a deflected manner. This effectively improves the filtration effect of the dustproof plate's convection ventilation, preventing a large amount of dust and pollutants from entering the fan coil unit and causing harm, thus achieving a good dust filtration effect.

[0016] Secondly, due to the presence of the second sealing plate, when the screw is turned, the shaft can rotate in place at the end of the screw, and the second sealing plate will move along the slide groove. When the second sealing plate changes, the airflow at the air inlet will also change, which makes it easier for the user to adjust the airflow. When the fan coil unit is not in use, the second sealing plate can also completely seal the air inlet, thus achieving a good sealing and protection effect. Attached Figure Description

An air inlet 18 is provided, which is connected to the ventilation opening 2. A protective plate 15 is installed on one side of the fan coil unit 1. During use, the airflow can be facilitated through the ventilation opening 2 and the air inlet 18. Two baffles 3 are provided, and their installation points are opposite. The two baffles 3 can effectively block and protect the inside of the ventilation opening 2. At the same time, the airflow can enter the air inlet 18 in a deflection manner, which can also effectively improve the filtration effect of the dustproof plate 5 for convection ventilation, so as to block a large amount of dust and pollutants in the ventilation opening 2, so that they cannot enter the fan coil unit 1 and cause harm.

[0025] refer to Figures 1 to 3 A limiting groove 4 is provided at the bottom inner side of the vent 2. A limiting block 6 matching the limiting groove 4 is fixedly connected to the bottom of the dustproof plate 5. The limiting block 6 is snapped into the inner side of the limiting groove 4. The dustproof plate 5 is snapped into the inner side of the vent 2 through the limiting groove 4 and the limiting block 6. A first sealing plate 7 is fixedly connected to the top of the dustproof plate 5. The first sealing plate 7 covers the top of the strip opening 10. A protrusion 8 is fixedly connected to the top of the first sealing plate 7. The protrusion 8 has an arc-shaped corner. Due to the presence of the limiting block 6, the insertion of the limiting block 6 can effectively limit the position of the dustproof plate 5, thereby preventing the dustproof plate 5 from shifting. When it is necessary to remove the dustproof plate 5, the limiting block 6 can be pulled out of the limiting groove 4. It is also convenient for users to clean or maintain the dustproof plate 5 later.

[0026] refer to Figures 1 to 5 The top of the fan coil unit 1 is provided with a slot 13, and the bottom of the top cover 9 is fixedly connected with a matching block 11. The block 11 is fixedly connected to the four sides of the bottom corner of the top cover 9, and the bottom of the block 11 is engaged with the inside of the slot 13. The top cover 9 is engaged with the top of the fan coil unit 1 through the slot 13 and the block 11. Due to the presence of the block 11, the engagement of the block 11 can effectively fix the position of the top cover 9, thereby preventing the top cover 9 from shifting. When it is necessary to remove the top cover 9, the block 11 can be pulled out of the slot 13. It also facilitates the user to inspect or maintain the inside of the fan coil unit 1 later.

[0027] refer to Figures 1 to 5A sealing groove 14 is provided at the top of the fan coil unit 1, and a sealing gasket 12 matching the sealing groove 14 is fixedly connected to the bottom of the top cover 9. The sealing gasket 12 covers the inner side of the sealing groove 14 and is located on the inner side of the adjacent locking block 11. Due to the presence of the sealing gasket 12, the sealing gasket 12 can effectively seal the connection point between the fan coil unit 1 and the top cover 9, thereby improving the overall sealing performance of the fan coil unit 1 and thus effectively improving the overall sealing and dustproof effect of the fan coil unit 1.

[0028] refer to Figure 1 and Figure 4 A second sealing plate 19 is slidably connected to one side of the tapered tube 17. A groove 20 matching the second sealing plate 19 is provided on one side of the tapered tube 17. The second sealing plate 19 is slidably connected to one side of the tapered tube 17 through the groove 20. A rotating shaft 21 is rotatably connected to the front side of the second sealing plate 19. A screw 23 is fixedly connected to the front side of the rotating shaft 21. A first screw hole 22 matching the screw 23 is provided on the front side of the fan coil unit 1. The screw 23 is threaded into the inner side of the first screw hole 22. With the presence of the sealing plate 19, when the screw 23 is turned, the rotating shaft 21 can rotate at the end of the screw 23 in its original position, and the second sealing plate 19 will move along the slide groove 20 accordingly. When the second sealing plate 19 changes, the airflow through its air inlet 18 will also change accordingly, which makes it easier for the user to adjust the airflow. When the fan coil unit 1 is not in use, the second sealing plate 19 can also completely seal the air inlet 18, thereby achieving a good sealing and protection effect.

[0029] refer to Figure 4 and Figure 5 A second screw hole 24 is provided on one side of the mounting plate 16. The second screw hole 24 extends into the interior of the fan coil body 1. A bolt 25 is threaded into the inner side of the second screw hole 24. The bolt 25 is threaded into the interior of the fan coil body 1. The mounting plate 16 is threaded to the inner wall of the fan coil body 1 through the second screw hole 24 and the bolt 25. Due to the presence of the bolt 25, the bolt 25 can be screwed in to effectively fix the position of the mounting plate 16, thereby preventing the mounting plate 16 from shifting. When it is necessary to remove the mounting plate 16, the bolt 25 can be unscrewed from the second screw hole 24. This also facilitates the user to disassemble and maintain the tapered tube 17 later.

[0030] refer to Figure 1The fan coil unit 1 has an opening 26 on its front side, which communicates with the inside of the fan coil unit 1. A transparent glass 27 is fixedly connected to the inside of the opening 26, covering the inside of the opening 26. Because of the opening 26, the user can directly view the inside of the fan coil unit 1 through the transparent glass 27 without opening the fan coil unit 1, which is conducive to the user to observe the operation status inside the fan coil unit 1 at all times, so as to improve the safety of the fan coil unit 1.

[0031] Operating principle and advantages: During use, the airflow is facilitated through the vent 2 and the air inlet 18. Two baffles 3 are provided, installed at opposite points. These two baffles 3 effectively block and protect the inside of the vent 2, while also allowing the flowing air to enter the air inlet 18 in a deflected manner. This effectively improves the filtration effect of the dustproof plate 5, preventing a large amount of dust and pollutants from entering the fan coil unit 1 and causing harm. The presence of the limiting block 6 effectively limits the position of the dustproof plate 5, thus preventing dust from entering the fan coil unit 1. If the dust cover 5 shifts, when it needs to be removed, simply pull the limiting block 6 out of the limiting groove 4. This also facilitates later cleaning or maintenance of the dust cover 5. Due to the presence of the locking block 11, the locking block 11 effectively fixes the position of the top cover 9, thus preventing displacement. When it needs to be removed, simply pull the locking block 11 out of the locking groove 13. This also facilitates later inspection or maintenance of the inner side of the fan coil unit 1. Due to the presence of the sealing gasket 12, the sealing gasket 12 effectively seals the connection point between the fan coil unit 1 and the top cover 9, thereby improving... The high overall sealing performance of the fan coil unit 1 effectively improves its overall sealing and dustproof effect. Due to the presence of the second sealing plate 19, when the screw 23 is turned, the shaft 21 can rotate at the end of the screw 23 in its original position, and the second sealing plate 19 will move along the slide groove 20 accordingly. As the second sealing plate 19 changes, the airflow through its air inlet 18 also changes, allowing the user to adjust the airflow. When the fan coil unit 1 is not in use, the second sealing plate 19 can also completely seal the air inlet 18, thus achieving good sealing and dustproof performance. The presence of bolts 25 effectively secures the mounting plate 16, preventing displacement. When the mounting plate 16 needs to be removed, bolts 25 can be unscrewed from the second screw hole 24. This also facilitates the user's later disassembly and maintenance of the tapered tube 17. Due to the opening 26, the user can directly view the inside of the fan coil unit 1 through the transparent glass 27 without opening the fan coil unit 1, thus allowing the user to constantly observe the operating status inside the fan coil unit 1 and improve its safety.
