Description

Technical Field

[0001] This application relates to the technical field of central air conditioning outdoor units, and in particular to a protective component for central air conditioning outdoor units. Background Technology

[0002] The outdoor unit of a central air conditioning system is usually fixed to the wall or placed on the roof platform by brackets. Without vibration damping, vibration energy will be transmitted and spread in a disorderly manner, which will lead to a series of chain problems such as equipment damage, noise pollution, and structural safety hazards.

[0003] In related technologies, since the outdoor unit and the bracket are generally directly connected by fastening bolts, when the outdoor unit is running, the core components (such as the compressor, fan motor, and heat exchanger) will generate periodic vibrations. The vibrations will directly act on the outdoor unit body and internal connecting parts. Due to the lack of vibration damping and buffering, when the outdoor unit is working for a long time, the screws on the outdoor unit casing, pipe joints, electrical wiring terminals, etc. will gradually loosen. In severe cases, it may cause refrigerant leakage (affecting cooling / heating) and poor circuit contact (leading to shutdown / malfunction). Utility Model Content

[0004] In order to appropriately reduce the vibration of the outdoor unit of a central air conditioning unit during operation, this application provides a protective component for the outdoor unit of a central air conditioning unit.

[0005] The protective component for a central air conditioning outdoor unit provided in this application adopts the following technical solution:

[0006] A protective assembly for a central air conditioning outdoor unit is disposed below the outdoor unit, including a base beam that provides support for the outdoor unit. A pad beam is disposed between the base beam and the outdoor unit, and the outdoor unit is mounted on the pad beam. Multiple mounting points are provided between the pad beam and the outdoor unit. Vibration damping connectors are provided at each mounting point on the pad beam. The vibration damping connectors have movable parts and fixed parts disposed inside and outside. The movable parts have an upwardly extending rod. A mounting base is provided at the bottom of the outdoor unit. Fasteners are provided between the rod and the mounting base to connect the mounting base and the movable parts.

[0007] Optionally, the fixing member is a housing integrally set on the pad beam. The housing is open from top to bottom. The movable member includes a main body set inside the housing. At least one end of the main body extends out of the housing and is connected to a support plate. The main body and the support plate form a through hole in the middle. The rod passes through the hole and extends outward.

[0008] Optionally, a support plate is also provided at the end of the main body away from the mounting base. A gap is reserved between the two support plates and the housing. A pad is provided in the gap. One end of the pad is fixedly connected to the support plate, and the other end extends into the housing and is fixedly connected to the main body.

[0009] Optionally, the vibration damping connector further includes an elastic component disposed between the movable component and the fixed component, wherein a groove is provided on the outer surface of the movable component, and the elastic component extends into the groove and connects with the movable component.

[0010] Optionally, the movable component is a cylindrical structure, and the elastic component is provided in two sets, with the two sets of elastic components spaced vertically and vertically along the axial direction of the movable component. One set of elastic components is a metal damping structure, and the other set of elastic components is rubber.

[0011] Optionally, a cavity is reserved between the outdoor unit and the pad beam and base beam, and a water receiving plate is provided in the cavity to receive condensate or defrost water discharged from the drain outlet at the bottom of the outdoor unit. At least one side of the water receiving plate is configured as an opening and extends outward.

[0012] Optionally, the water receiving plate has a U-shaped cross-section, and a fastener is provided on the side of the water receiving plate facing the pad beam. A corresponding mounting plate is provided on the side wall of the pad beam. A fastener groove is provided on the mounting plate, and the fastener can be placed in the fastener groove to detachably connect the water receiving plate and the pad beam.

[0013] Optionally, four of the mounting plates and buckles are provided, with two mounting plates distributed along the length of the pad beam not at the same height, so that the water receiving plate is inclined and an opening is formed on the lowest side of the inclined direction of the water receiving plate.

[0014] Optionally, the inner bottom surface of the water receiving plate is provided with spaced guide strips, one end of which is fixed to the opening and extends along the inclined direction of the water receiving plate.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. By installing vibration damping connectors between the support beam and the outdoor unit of the central air conditioner, the outdoor unit is connected to the vibration damping connectors. When the outdoor unit is working, most of the vibrations it generates are transmitted to the vibration damping connectors. The installation of the vibration damping connectors plays a buffering role, appropriately reducing the noise generated by the outdoor unit during operation, so that the outdoor unit body and internal connectors can remain stable for a long time, thereby ensuring the normal operation of the outdoor unit.

[0017] 2. By installing a water collection plate under the outdoor unit, the condensate or defrost water discharged during the operation of the outdoor unit falls directly onto the water collection plate and is then discharged to the outside through the water collection plate. This can prevent the condensate or defrost water from accumulating under the outdoor unit, prevent the pad beam and base beam from rusting, and ensure the stability of the outdoor unit installation.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a protective component for the outdoor unit of a central air conditioning system. (Refer to...) Figure 1 A protective component for a central air conditioning outdoor unit is disclosed, installed below the outdoor unit to provide support and vibration damping. It includes a base beam 1, laid on a foundation such as a concrete platform at the installation location of the outdoor unit. Two pad beams 2 are installed on the base beam 1, perpendicular to each other. The two base beams 1 are located on the outer and rear sides of the bottom of the outdoor unit and extend along its length. The two pad beams 2 are located on the left and right sides of the bottom of the outdoor unit and extend along its width. The combined arrangement of the base beams 1 and pad beams 2 forms a grid-like foundation support structure.

[0025] Two mounting bases 4 are provided at the bottom of the outdoor unit. The two mounting bases 4 are located on both sides of the outdoor unit and are parallel to the pad beam 2. At the two ends of each mounting base 4, corresponding to the pad beam 2, mounting points are formed. Vibration damping connectors 3 are provided at the mounting points. The mounting base 4 is connected to the vibration damping connectors 3. When the outdoor unit is working and vibrates, most of the vibration is transmitted to the vibration damping connectors 3, which can play a role in buffering and damping vibration.

[0026] Furthermore, the vibration damping connector 3 includes a movable part 31, a fixed part 32, and an elastic component 35 disposed inside and outside. A through hole is formed at the mounting point of the pad beam 2. The fixed part 32 is specifically a shell disposed in the through hole and integrally connected to the pad beam 2. The shell is preferably a cylindrical structure with both ends open, and the axial direction of the shell is parallel to the height direction of the outdoor unit. The movable part 31 includes a main body 311 disposed in the shell. The main body 311 is located in a columnar structure coaxially disposed in the shell, and the outer diameter of the main body 311 is smaller than the inner diameter of the shell, so as to reserve a buffer space between the movable part 31 and the fixed part 32. The elastic component 35 is disposed in the buffer space.

[0027] Furthermore, two sets of grooves are formed on the outer side of the main body 311. These two sets of grooves are located on a horizontal plane and are spaced apart along the axial direction of the main body 311. Two sets of elastic components 35 are provided, each corresponding to one of the two sets of grooves. One set of elastic components 35 is rubber fixed between the fixed member 32 and the movable member 31, and the other set of elastic components 35 is a metal damping structure fixed between the fixed member 32 and the movable member 31. The specific arrangement of the rubber and metal damping structures is common knowledge and will not be elaborated upon here.

[0028] Reference Figure 2 and Figure 4 The main body 311 has two ends extending to the outer side of the housing and connected to support plates 312. A gap is left between the two support plates 312 and the housing, and a pad 313 is placed in this gap. One end of the pad 313 is fixedly connected to the support plate 312, and the other end extends into the housing and is fixedly connected to the main body 311. Through holes are respectively opened in the middle of the main body 311 and the two support plates 312. A rod 33 is placed in the hole, with both ends extending to the outer side of the two support plates 312. External threads are provided at the outer ends of the rod 33. The end of the rod 33 away from the outdoor unit is fixedly connected to the corresponding support plate 312 by a fastener 34, and the end closer to the outdoor unit is fixedly connected to the mounting base 4 by a fastener 34. At this time, the mounting base 4 and the support plate 312 abut against each other. The vibration generated during the operation of the outdoor unit is transmitted to the movable part 31 through the rod 33, causing the movable part 31 to move relative to the fixed part 32, which in turn drives the elastic component 35 to move, thereby achieving the purpose of buffering and vibration reduction.

[0029] Reference Figure 4 A cavity is reserved between the outdoor unit and the pad beam 2 and the base beam 1. A water receiving plate 5 is installed in the cavity. The water receiving plate 5 adopts a U-shaped box structure to receive the condensate and defrost water discharged from the drain outlet at the bottom of the outdoor unit.

[0030] To facilitate the installation and disassembly of the water receiving plate 5, the following connection structure can be adopted: two fasteners 6 are respectively installed on the sides of the water receiving plate 5 facing the two side pad beams 2, and the two fasteners 6 are at the same height; corresponding to the fasteners 6, two mounting plates 7 are respectively installed on the sides of the two pad beams 2 facing the water receiving plate 5, the two mounting plates 7 are not at the same height, and a fastening groove is formed on each mounting plate 7, and the fasteners 6 can be placed in the fastening groove to achieve a detachable connection between the water receiving plate 5 and the pad beam 2.

[0031] Since the two mounting plates 7 on the same side are not at the same height and the fasteners 6 that cooperate with them are at the same height, the water receiving plate 5 installed in the cavity is inclined, with one side higher than the other side. An opening is formed on the lowest side of the water receiving plate 5 in the direction of inclination. When condensate falls on the water receiving plate 5, it can flow along the direction of inclination of the water receiving plate 5 to the opening, and then be discharged to the outside through the opening.

[0032] Furthermore, multiple guide strips 8 are provided at intervals on the inner bottom surface of the water receiving plate 5. A flow channel for condensate or defrost water is formed between two adjacent guide strips 8. One end of the guide strip 8 is fixed at the opening and extends along the inclined direction of the water receiving plate 5 to improve the discharge efficiency of condensate or defrost water.

[0033] This application embodiment provides a central air conditioning outdoor unit protection component. By providing a vibration damping connector 3 between the pad beam 2 and the outdoor unit of the central air conditioning, the outdoor unit is connected to the vibration damping connector 3. When the outdoor unit is working, most of the vibration generated is transmitted to the vibration damping connector 3. The vibration damping connector 3 plays a buffering role, appropriately reducing the noise generated by the outdoor unit during operation, so that the outdoor unit body and internal connectors can remain stable for a long time, thereby ensuring the normal operation of the outdoor unit.

[0034] By installing a water receiving plate 5 under the outdoor unit, the condensate or defrost water discharged during the operation of the outdoor unit falls directly onto the water receiving plate 5 and is then discharged to the outside through the water receiving plate 5. This can prevent the condensate or defrost water from accumulating under the outdoor unit, prevent the pad beam 2 and the base beam 1 from rusting, and ensure the stability of the outdoor unit installation.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
