Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a vertical exposed fan coil unit for central air conditioning. Background Technology

[0002] Vertical exposed fan coil units are one of the core terminal devices in central air conditioning systems, used to regulate indoor temperature and air quality. They are characterized by their vertical structure and exposed installation (no need for ceiling concealment), typically made of galvanized steel or aluminum alloy with a rust-proof paint coating, balancing aesthetics and durability, and driven by a motor to deliver air.

[0003] The air inlet of a vertical exposed fan coil unit needs to be fitted with a filter to prevent dust and impurities from entering. However, the filter needs to be disassembled, replaced and cleaned after being clogged for a long time, which affects the continuity of the filtration work. Moreover, the disassembly work is cumbersome and requires the removal of many screws. Therefore, a vertical exposed fan coil unit for central air conditioning is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that the filter screen needs to be disassembled and replaced after being clogged after long-term use, which affects the continuity of the filtration work and the disassembly work is relatively cumbersome and requires the removal of many screws. Therefore, a vertical exposed fan coil unit for central air conditioning is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vertical exposed fan coil unit for central air conditioning includes a fan coil unit with an air inlet on its side. A first filter and a second filter are movably connected to the inner side of the fan coil unit. An alternating use assembly for the first and second filters is provided on the inner side of the fan coil unit. The alternating use assembly includes a transmission unit on the inner side of the fan coil unit, a movable rod slidably disposed on the inner side of the fan coil unit, fixed rods symmetrically mounted on the side of the movable rod, a U-shaped rod movably connected to the inner side of the fixed rod, two telescopic plates slidably disposed on the inner side of the fan coil unit, and two compression rods movably connected to the side of the fan coil unit. A first fixing groove is provided on the inner side of both the first and second filters. A second fixed slot is provided, and pressure plates are symmetrically installed on the inner side of the fan coil unit. The transmission unit drives the first and second filters to move through the movable rod, so that the first and second filters correspond to the air inlet respectively and work alternately to realize the immediate replacement of the filtration function and ensure the continuity of filtration. After the U-shaped rod squeezes the pressure plate, it moves to the inner side of the fixed rod and then to the outer side of the second fixed slot. It presses the squeezing rod and pushes the first and second filters in the corresponding positions. The first and second filters separate from the fixed rod and squeeze the telescopic plate through the third opening slot to move to the outer side of the fan coil unit. The replaced first and second filters can be directly pulled out to the outer side of the fan coil unit for quick processing.

[0007] The above technical solution further includes:

[0008] The fan coil unit has a sliding groove on its inner side, and a sliding block is slidably arranged on the inner side of the sliding groove. The sliding block is fixedly connected to the movable rod, and the movable rod moves along the sliding groove through the sliding block.

[0010] The fixed rod has a first opening groove on its inner side, and a guide rod is installed on the inner side of the first opening groove. The guide rod is slidably connected to the U-shaped rod. A first spring is installed at the bottom of the U-shaped rod. The end of the first spring away from the U-shaped rod is fixedly connected to the inner wall of the first opening groove. The U-shaped rod is retracted into the inner side of the first opening groove by the support of the guide rod.

[0011] The size of the first fixing groove opening is adapted to the size of the fixing rod, and the size of the second fixing groove opening is adapted to the size of the end of the U-shaped rod.

[0012] Two third springs are installed on the side of the fan coil unit. The end of the third spring away from the fan coil unit is fixedly connected to the extrusion rod. The first filter screen and the second filter screen are both on the movement trajectory of the extrusion rod. When the extrusion rod is pressed, it moves to the inside of the fan coil unit and pushes the first filter screen and the second filter screen at the same time.

[0013] The fan coil unit has two third opening slots on its side, and a second opening slot is provided inside the third opening slot. A second spring is installed inside the second opening slot, and the end of the second spring is fixedly connected to the telescopic plate. The telescopic plate is slidably connected to the second opening slot.

After the U-shaped rod 12 squeezes the pressure plate 13, it moves to the inner side of the fixing rod 8 and then to the outer side of the second fixing slot 20. It presses the squeezing rod 14 and pushes the first filter screen 6 and the second filter screen 7 in the corresponding position. The first filter screen 6 and the second filter screen 7 separate from the fixing rod 8 and squeeze the telescopic plate 18 through the third opening slot 21 to move to the outer side of the fan coil unit 1. The replaced first filter screen 6 and second filter screen 7 can be directly pulled out to the outer side of the fan coil unit 1 for quick processing.

[0026] A sliding groove 3 is provided on the inner side of the fan coil unit 1, and a sliding block 4 is slidably arranged on the inner side of the sliding groove 3. The sliding block 4 is fixedly connected to the movable rod 5, and the movable rod 5 moves along the sliding groove 3 through the sliding block 4.

[0027] The transmission unit includes a servo motor 22 installed inside the fan coil unit 1. A threaded rod 23 is installed at the output end of the servo motor 22. The threaded rod 23 is rotatably connected to the fan coil unit 1. The threaded rod 23 is threadedly connected to the movable rod 5. The servo motor 22 drives the threaded rod 23 to rotate. When the threaded rod 23 rotates, it drives the movable rod 5 to move.

[0028] The inner side of the fixed rod 8 is provided with a first opening groove 9, and a guide rod 10 is installed on the inner side of the first opening groove 9. The guide rod 10 is slidably connected to the U-shaped rod 12. A first spring 11 is installed at the bottom of the U-shaped rod 12. The end of the first spring 11 away from the U-shaped rod 12 is fixedly connected to the inner wall of the first opening groove 9. The U-shaped rod 12 is retracted into the inner side of the first opening groove 9 by the support of the guide rod 10.

[0029] The size of the opening of the first fixing groove 19 is adapted to the size of the fixing rod 8, and the size of the opening of the second fixing groove 20 is adapted to the size of the end of the U-shaped rod 12.

[0030] Two third springs 15 are installed on the side of the fan coil unit 1. The end of the third spring 15 away from the fan coil unit 1 is fixedly connected to the extrusion rod 14. The first filter screen 6 and the second filter screen 7 are both on the movement trajectory of the extrusion rod 14. When the extrusion rod 14 is pressed, it moves to the inside of the fan coil unit 1, and at the same time pushes the first filter screen 6 and the second filter screen 7.

[0031] Two third opening slots 21 are provided on the side of the fan coil unit 1. A second opening slot 16 is provided on the inner side of the third opening slot 21.
