Description

Technical Field

[0001] This utility model relates to the field of fan coil unit installation technology, specifically a concealed noise-reducing fan coil unit. Background Technology

[0002] Fan coil units, also known as fan coil units, are one of the terminal devices in an air conditioning system, consisting of a small fan, motor, and coil. Fan coil units are typically embedded and suspended in the ceiling, flush with the ceiling panels for concealed installation.

[0003] When hoisting fan coil units, the common practice is to install two layers of vibration damping components at the bottom of the hoisting wire and the unit installation location. However, during operation, the vibration generated by the fan coil unit is not unidirectional. Multiple factors, such as the operation of the fan coil unit's motor, the rotation of the impeller, and the impact of water flow, jointly cause lateral displacement in the horizontal direction, vertical vibration in the vertical direction, and even torsional swaying. At the same time, since the hoisting wire is in direct contact with the fan coil unit, the vibration energy generated by the unit will be transmitted to the hoisting wire, causing the hoisting wire to vibrate at high frequency with the unit, thus generating harsh mechanical noise that affects the comfort of the indoor environment. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a concealed noise-reducing fan coil unit to solve the problems mentioned in the background. This utility model has a novel structure. Compared with the conventional approach of setting two layers of vibration damping components at the bottom of the suspension wire and the unit installation location, the connection noise reduction components of this concealed noise-reducing fan coil unit adopt a combination of multiple structures to decompose, buffer, and absorb vibrations from multiple directions. It can more comprehensively and effectively cope with the complex vibrations generated during the operation of the fan coil unit, significantly reduce the vibration amplitude, reduce mechanical noise caused by vibration, and improve the comfort of the indoor environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concealed noise-reducing fan coil unit, comprising a fan coil unit body, mounting plates at the four corners of the fan coil unit body, mounting blocks on the outer side of the mounting plates, lifting wires on the outer side of the mounting blocks, a noise-reducing connection assembly between the mounting plates and the mounting blocks, connecting ears fixedly mounted on the outer side of the mounting blocks, the lifting wires inserted into the holes of the connecting ears, nuts threaded around the upper and lower sides of the connecting ears, mounting bolts connecting the fan coil unit body to the upper side of the mounting plates, and the noise-reducing connection assembly comprising symmetrically arranged inclined blocks on the upper and lower sides of the mounting plates, with symmetrically arranged inclined grooves on one side of the mounting blocks facing the two inclined blocks on the mounting plates, the inclined sides of the inclined grooves being parallel to the inclined sides of the inclined blocks.

[0006] Furthermore, the mounting block has a groove on the inner side facing the mounting plate, the extension lines of the two inclined grooves intersect at the center of the groove, and a first T-shaped groove is formed on the upper side of the inclined grooves of the two inclined grooves, and a first T-shaped block is slidably fitted on the inner wall of the first T-shaped groove.

[0007] Furthermore, a second T-shaped block is provided on the upper side of the first T-shaped block, and a first damper and a first damping spring are installed between the bottom of the second T-shaped block and the upper side of the first T-shaped block.

[0008] Furthermore, a second T-shaped groove is provided on the inclined side of the two inclined blocks, and the two second T-shaped blocks are slidably engaged in the two second T-shaped grooves. The two second T-shaped grooves are provided with an embedding groove that engages with the two second T-shaped blocks.

[0009] Furthermore, a third T-shaped groove is provided at the bottom of the groove, and a third T-shaped block is slidably fitted on the inner wall of the third T-shaped groove.

[0010] Furthermore, a second damper and a second damping spring are installed between the two sides of the third T-shaped block and the inner walls of the two sides of the third T-shaped groove.

[0011] Furthermore, a connecting block is provided on the side of the third T-shaped block facing the mounting plate, and a third damper and a third damping spring are installed between the rear side of the connecting block and the front side of the third T-shaped block.

[0012] Furthermore, the front side of the connecting block is provided with a connecting groove with a convex cross-section, and the mounting plate is provided with a T-shaped sliding groove on the side facing the connecting block. The transverse side of the T-shaped sliding groove extends to the outside of both sides of the mounting plate. L-shaped blocks are slidably fitted on both sides inside the T-shaped sliding groove. A return spring is installed between the two L-shaped blocks, and a locking block that cooperates with the connecting groove is installed at the outer end of the two L-shaped blocks.

[0013] The beneficial effects of this utility model are:

[0014] 1.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 6This utility model provides a technical solution: a concealed noise-reducing fan coil unit, including a fan coil unit body 1, with mounting plates 2 at the four corners of the fan coil unit body 1, mounting blocks 3 on the outer side of the mounting plates 2, and hanging wires 4 on the outer side of the mounting blocks 3. A noise-reducing connection component 5 is provided between the mounting plates 2 and the mounting blocks 3, and connecting ears 6 are fixedly installed on the outer side of the mounting blocks 3. The hanging wires 4 are inserted into the holes of the connecting ears 6, and nuts 7 are threaded on the upper and lower sides of the hanging wires 4 located on the connecting ears 6. Mounting bolts 8 are provided on the upper side of the mounting plates 2 to connect with the fan coil unit body 1. The noise-reducing connection component 5 includes inclined blocks 501 symmetrically arranged on the upper and lower sides of the mounting plates 2. The mounting blocks 3 have symmetrically arranged inclined grooves 502 on one side facing the two inclined blocks 501 on the mounting plates 2. The inclined sides of the inclined grooves 502 are parallel to the inclined sides of the inclined blocks 501.

[0025] Specifically, through the multiple vibration reduction effects of the noise reduction component 5, the vibration transmitted from the fan coil unit body 1 to the mounting block 3 is weakened. The mounting block 3 is connected to the hanging wire 4 through the connecting ear 6. Since the vibration has been effectively reduced, the vibration energy transmitted to the hanging wire 4 is greatly reduced, thereby reducing the mechanical noise generated by the high-frequency vibration of the hanging wire 4.

[0026] In this embodiment, the mounting block 3 has a groove 503 on its inner side facing the mounting plate 2. The extension lines of the inclined sides of the two inclined grooves 502 intersect at the center of the groove 503. A first T-shaped groove 507 is formed on the upper side of the inclined sides of the two inclined grooves 502. A first T-shaped block 504 is slidably fitted on the inner wall of the first T-shaped groove 507. A second T-shaped block 505 is provided on the upper side of the first T-shaped block 504. A first damper 508 and a first damping spring 509 are installed between the bottom of the second T-shaped block 505 and the upper side of the first T-shaped block 504. A second T-shaped groove 506 is formed on the inclined sides of the two inclined blocks 501. The two second T-shaped blocks 505 are slidably fitted in the two second T-shaped grooves 506. The two second T-shaped grooves 506 have outwardly formed embedding grooves 9 that cooperate with the two second T-shaped blocks 505.

[0027] Specifically, under vibration, the inclined blocks 501 on the upper and lower sides of the mounting plate 2 slide within the inclined grooves 502 on the mounting block 3. Since the inclined sides of the grooves 502 and 501 are parallel, and the inward extensions of the inclined sides of the two grooves 502 intersect at the center of the groove 503, this special structural design allows the inclined blocks 501 to decompose and buffer vibrations from different directions during sliding. Simultaneously, the first T-shaped block 504 slides within the first T-shaped groove 507, and the second T-shaped block 505 slides within the second T-shaped groove 506. The first damper 508 and the first damping spring 509 act as dampers, absorbing vibration energy and reducing vibration transmission, thus buffering vibrations in both vertical and torsional directions.

[0028] In this embodiment, a third T-shaped groove 510 is formed at the bottom of the groove 503. A third T-shaped block 511 is slidably fitted on the inner wall of the third T-shaped groove 510. A second damper 512 and a second damping spring 513 are installed between the two sides of the third T-shaped block 511 and the two inner walls of the third T-shaped groove 510. A connecting block 514 is provided on the side of the third T-shaped block 511 facing the mounting plate 2. A third damper 515 and a second damping spring 513 are installed between the rear side of the connecting block 514 and the front side of the third T-shaped block 511. The three-damping spring 516, the connecting block 514 has a connecting groove 517 with a convex cross-section on the front side, the mounting plate 2 has a T-shaped slide groove 518 on the side facing the connecting block 514, the transverse side of the T-shaped slide groove 518 extends to the outside of both sides of the mounting plate 2, the two sides of the T-shaped slide groove 518 are slidably fitted with L-shaped blocks 519, a return spring 520 is installed between the two L-shaped blocks 519, and the outer ends of the two L-shaped blocks 519 are fitted with a locking block 521 that cooperates with the connecting groove 517.

[0029] Specifically, the third T-shaped block 511 at the bottom of the groove 503 slides within the third T-shaped groove 510, and the second dampers 512 and second damping springs 513 on both sides can absorb horizontal vibration energy. The connecting block 514 on the front side of the third T-shaped block 511, along with the third damper 515 and third damping spring 516 between it and the third T-shaped block 511, can buffer horizontal vibration. The connecting groove 517 on the connecting block 514 cooperates with the L-shaped block 519 in the T-shaped slide groove 518 on the mounting plate 2, and the locking block 521 cooperates with the connecting groove 517 to ensure the stability of the connection between the mounting plate 2 and the mounting block 3.
