Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, specifically to an air source heat pump with a sound insulation structure. Background Technology

[0002] With people's increasing pursuit of a comfortable living environment and the popularization of environmental protection and energy conservation concepts, air source heat pumps, as highly efficient and energy-saving heating and cooling equipment, are increasingly widely used in homes and commercial spaces. When traditional air source heat pumps are running, the compressor, fan, and other components generate considerable noise, mainly from mechanical vibration and airflow disturbance. However, traditional sound insulation solutions do not fully consider the balance between the heat dissipation needs of the main unit and the sound insulation effect. Some soundproof covers can reduce noise but hinder the heat dissipation of the main unit, resulting in excessively high operating temperatures, affecting the stability and service life of the equipment; or they sacrifice sound insulation to ensure heat dissipation, failing to meet users' requirements for a quiet environment.

[0003] Therefore, developing an ultra-low noise air source heat pump that can effectively reduce noise while also meeting heat dissipation requirements and is easy to install and maintain has become an urgent problem for the industry. Utility Model Content

[0004] The purpose of this utility model is to provide an air source heat pump unit with a sound insulation structure to solve the problem mentioned in the background art that the air source heat pump unit cannot simultaneously achieve noise reduction and heat dissipation during operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air source heat pump unit with a sound insulation structure, comprising a main unit frame, a condenser fixedly installed inside the main unit frame, a compressor fixedly installed inside the main unit frame, one end of the compressor being connected to the condenser, one end of the condenser penetrating the outer surface of the main unit frame, and the outer surface of the main unit frame being penetrated by one end of the compressor, an intermediate adapter plate fixedly installed on the outer surface of the main unit frame, a fixed base plate fixedly installed on the ground at one end of the intermediate adapter plate, a spring being provided between the intermediate adapter plate and the fixed base plate, and an elastic support mechanism being provided between the fixed base plate and the intermediate adapter plate.

[0006] Preferably, the elastic support mechanism includes: support locking rubber, which is respectively locked onto the outer surface of the intermediate transition plate and the fixed base plate, and the support locking rubber between the intermediate transition plate and the fixed base plate is staggered; a universal connecting rod is rotatably installed between the support locking rubber, and the universal connecting rod is locked onto the support locking rubber; the spring, the support locking rubber and the universal connecting rod are respectively set at the four corners of the intermediate transition plate and the fixed base plate; and shock-absorbing pads are fixedly installed between the main frame and the compressor.

[0007] Using the above technical solution, the universal linkage is rotatably installed between and engaged with the support locking rubber, which can disperse and absorb vibration energy in multiple directions. In addition, the shock-absorbing pads fixedly installed between the main frame and the compressor further reduce the vibration impact of the compressor on the main frame during operation, making the air source heat pump unit more stable during operation and reducing the transmission of noise caused by vibration.

[0008] Preferably, a cooling fan is fixedly installed on the outer surface of the main frame, and the cooling fan is located above the condenser. A protective cover is provided at one end of the main frame near the cooling fan. Dust filter plates are evenly distributed on the outer surface of the main frame, and the dust filter plates are located on three sides of the main frame. The condenser has a U-shaped design. The dust filter plates are fixed to the main frame with screws.

[0009] By adopting the above technical solution, the cooling fan can accelerate airflow and enhance the heat dissipation effect of the condenser. The condenser adopts a concave design to increase the heat dissipation area and improve the heat dissipation efficiency. At the same time, the dust filter can also play a certain role in sound insulation, reducing the transmission of noise to the outside, and can effectively block dust from entering the main frame. The dust filter can also be removed and cleaned to ensure the cleanliness of the internal components of the main frame, extend the service life of the equipment, and ensure that the heat dissipation efficiency is not reduced.

[0010] Preferably, the inner surface of the main frame is covered with water-repellent sound-absorbing cotton, and the water-repellent sound-absorbing cotton is laid on the inner surface of the main frame near the middle adapter plate, and the water-repellent sound-absorbing cotton is laid on the inner surface of the main frame near the compressor.

[0011] Using the above technical solution, the hydrophobic sound-absorbing cotton has good sound absorption performance and can effectively absorb the noise generated inside the host. At the same time, the water-repellent property of the hydrophobic sound-absorbing cotton can maintain stable performance in humid environments and avoid the sound absorption effect being affected by moisture.

[0012] Preferably, the bottom of the main frame is designed to be inclined, and a water storage tank is fixedly installed on the outer surface of one end of the main frame near the middle adapter plate. The side surface of the water storage tank is provided with through holes, and a suction and heat dissipation mechanism is provided between the water storage tank and the compressor.

[0013] By adopting the above technical solution, the condensate water condensed by the condenser can be conveniently collected, allowing the condensate water to be collected into the water storage tank along the inclined surface of the main frame. At the same time, the through holes on the side surface of the water storage tank can discharge excess condensate water, so that the condensate water can be recycled and reused.

[0014] Preferably, the suction and heat dissipation mechanism includes: a water pump, which is fixedly installed on the outer surface of the main frame, one end of which extends into the interior of the water storage tank; the outer surface of the compressor is covered with heat dissipation and water absorption cotton, and the outer surface of the heat dissipation and water absorption cotton is in close contact with the outer surface of the compressor; a drain groove is inserted into the outer surface of the compressor, and the outer surface of the drain groove is uniformly provided with through holes, and the outer surface of the drain groove is in contact with the outer surface of the heat dissipation and water absorption cotton.

[0015] Using the above technical solution, the collected condensate can be extracted by a water pump, allowing it to be discharged outward through the through-holes on the outer surface of the drain tank. The discharged condensate can then wet the heat-dissipating absorbent cotton covering the outer surface of the compressor. The evaporation of the condensate in the absorbent cotton carries away heat, thus cooling the compressor. Combined with the air drawn by the cooling fan, this accelerates the evaporation of the condensate in the absorbent cotton, improving the compressor's heat dissipation efficiency.

[0016] Preferably, a maintenance plate is fixedly installed on the outer surface of the main frame near the heat dissipation and water absorption cotton, and the main frame, compressor and maintenance plate are connected. The main frame and water-repellent sound-absorbing cotton are bound together.

[0017] By adopting the above technical solution, the interconnection design between the main frame, compressor and inspection panel facilitates the inspection and maintenance of the internal components of the main frame. The binding design between the main frame and the water-repellent sound-absorbing cotton facilitates the installation and replacement of the water-repellent sound-absorbing cotton. Moreover, when inspecting and replacing the components inside the main frame, it is only necessary to open the inspection panel.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the air source heat pump unit equipped with a sound insulation structure:

[0019] 1. The spring, supporting locking rubber, and universal joint between the intermediate transition plate and the fixed base plate form a buffer structure. The spring is fixed between the intermediate transition plate and the fixed base plate, playing a preliminary role in shock absorption. The supporting locking rubber is installed between the two in a staggered design, which further enhances the shock absorption effect. At the same time, its elastic deformation can adapt to vibrations in different directions. The universal joint is rotatably installed between the supporting locking rubber and engages with it, which can disperse and absorb vibration energy in multiple directions. The spring, supporting locking rubber, and universal joint are respectively set at the four corners to ensure the uniformity of support and shock absorption. The shock-absorbing pads fixedly installed between the main frame and the compressor further reduce the impact of compressor operation on the vibration of the main frame, making the main unit more stable during operation and reducing the transmission of noise caused by vibration.

[0020] 2. The hydrophobic sound-absorbing cotton laid inside the main unit frame can effectively absorb the noise emitted by the compressor and cooling fan when they are running. At the same time, due to the water-repellent properties of the hydrophobic sound-absorbing cotton, it can maintain stable performance in humid environments, avoiding the impact of moisture absorption on the sound absorption effect of the hydrophobic sound-absorbing cotton. The dust filter plate can also block some of the noise. Through the laying of hydrophobic sound-absorbing cotton and dust filter plate, a soundproof space is formed inside the main unit, reducing the amount of noise transmitted to the outside.

[0021] 3. As the condenser operates, moisture in the air will condense and fall into the interior of the main unit frame. The condensate will then collect in the water storage tank for easy collection. Simultaneously, the condensate can be drawn out by the water pump and evenly discharged outward through the drain trough. This allows the condensate to soak the heat dissipation absorbent cotton, and the evaporating moisture from the absorbent cotton quickly reduces the temperature generated during compressor operation, stabilizing the compressor temperature at a suitable level. This ensures stable compressor operation, improves the overall operational stability of the air source heat pump unit, and allows the produced condensate to be recycled. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: an air source heat pump unit with a sound insulation structure, including a main unit frame 1, a condenser 7 fixedly installed inside the main unit frame 1, a compressor 8 fixedly installed inside the main unit frame 1, and one end of the compressor 8 connected to the condenser 7. One end of the condenser 7 penetrates the outer surface of the main unit frame 1, and the outer surface of the main unit frame 1 is penetrated by one end of the compressor 8. An intermediate adapter plate 2 is fixedly installed on the outer surface of the main unit frame 1, and a fixed base plate 3 is fixedly installed on the ground at one end of the intermediate adapter plate 2. A spring 4 is provided between the intermediate adapter plate 2 and the fixed base plate 3, and an elastic support mechanism is provided between the fixed base plate 3 and the intermediate adapter plate 2.

[0031] As the compressor 8 operates, the refrigerant is compressed and circulated. At this time, the condenser 7 will exchange heat. The operation of the compressor 8 will transmit the vibration generated during rotation to the main frame 1, causing the main frame 1 and the intermediate transition plate 2 to vibrate together. The spring 4 is fixed between the intermediate transition plate 2 and the fixed base plate 3, which can play a preliminary shock absorption and buffering role, and initially reduce the noise generated by vibration.

[0032] The elastic support mechanism includes: support locking rubber 5, which is respectively locked onto the outer surface of the intermediate transition plate 2 and the fixed base plate 3, and the support locking rubber 5 between the intermediate transition plate 2 and the fixed base plate 3 is staggered. A universal connecting rod 6 is rotatably installed between the support locking rubber 5, and the universal connecting rod 6 is locked onto the support locking rubber 5. The spring 4, the support locking rubber 5 and the universal connecting rod 6 are respectively set at the four corners of the intermediate transition plate 2 and the fixed base plate 3. A shock-absorbing pad 9 is fixedly installed between the main frame 1 and the compressor 8.

[0033] The spring 4, the support locking rubber 5, and the universal connecting rod 6 are respectively set at the four corners of the intermediate adapter plate 2 and the fixed base plate 3, ensuring the uniformity of the support and shock absorption of the main frame 1 by the intermediate adapter plate 2. The support locking rubber 5 and the universal connecting rod 6 are snapped together between the intermediate adapter plate 2 and the fixed base plate 3 and are staggered, which further enhances the shock absorption effect. At the same time, the elastic deformation of the support locking rubber 5 and the universal connecting rod 6 can adapt to vibrations in different directions. The shock-absorbing pad 9 fixedly installed between the main frame 1 and the compressor 8 can further reduce the vibration impact of the compressor 8 on the main frame 1 during operation. With the use of the spring 4, the main frame 1 will not generate excessive noise due to the use of the compressor 8 and the cooling fan 11.

[0034] A cooling fan 11 is fixedly installed on the outer surface of the main unit frame 1, and the cooling fan 11 is located above the condenser 7. A protective cover is provided at one end of the main unit frame 1 near the cooling fan 11. Dust filter plates 16 are evenly distributed on the outer surface of the main unit frame 1, and the dust filter plates 16 are located on three sides of the main unit frame 1. The condenser 7 has a U-shaped design. The dust filter plates 16 are fixed to the main unit frame 1 with screws.

[0035] As the cooling fan 11 rotates, it draws outside air into the main unit frame 1. The air first passes through the dust filter 16, which filters out dust from the air, preventing it from entering the main unit frame 1 and affecting the internal components. This keeps the internal components of the main unit frame 1 clean, extending the service life of the equipment. At the same time, the dust filter 16 can also effectively block some of the noise generated by the air source heat pump during operation. The protective cover can effectively prevent debris from entering the cooling fan 11 and causing damage. The cooling fan 11 accelerates airflow and enhances the heat dissipation effect of the condenser 7. Meanwhile, the concave design of the condenser 7 increases the heat dissipation area and improves the heat dissipation efficiency.

[0036] The inner surface of the main frame 1 is covered with water-repellent sound-absorbing cotton 10, and the water-repellent sound-absorbing cotton 10 is laid on the inner surface of the main frame 1 near the middle adapter plate 2, and the water-repellent sound-absorbing cotton 10 is laid on the inner surface of the main frame 1 near the compressor 8.

[0037] By laying the hydrophobic sound-absorbing cotton 10 inside the main unit frame 1, the noise generated by the compressor 8 and cooling fan 11 running inside the main unit frame 1 is absorbed. At the same time, the hydrophobic properties of the hydrophobic sound-absorbing cotton 10 allow it to maintain stable performance even when the main unit frame 1 is in a humid environment, avoiding the sound absorption effect being affected by water and moisture. This allows the interior of the main unit frame 1 to absorb some of the noise. Furthermore, by adjusting the orientation of the main unit frame 1 so that the side of the condenser 7 faces the direction that does not require sound insulation, the chance of noise affecting itself is reduced.

[0038] The bottom of the main frame 1 is designed to be inclined, and a water tank 12 is fixedly installed on the outer surface of the main frame 1 near the middle adapter plate 2. The side surface of the water tank 12 is provided with through holes, and a suction and heat dissipation mechanism is provided between the water tank 12 and the compressor 8.

[0039] The inclined design inside the main frame 1 allows the condensate generated during the operation of the condenser 7 to be guided and flow into the interior of the water storage tank 12. The through holes on the side of the water storage tank 12 can release excess condensate, allowing the condensate to be recycled and reused.

[0040] The heat dissipation mechanism includes: a water pump 13, which is fixedly installed on the outer surface of the main frame 1. One end of the water pump 13 extends into the interior of the water storage tank 12. The outer surface of the compressor 8 is covered with heat dissipation and water absorption cotton 15, and the outer surface of the heat dissipation and water absorption cotton 15 is tightly attached to the outer surface of the compressor 8. A drain groove 14 is inserted into the outer surface of the compressor 8, and the outer surface of the drain groove 14 is evenly provided with through holes, and the outer surface of the drain groove 14 is attached to the outer surface of the heat dissipation and water absorption cotton 15.

[0041] When the air source heat pump is started, the water pump 13 will operate and extract the condensate inside the water storage tank 12, so that the condensate is evenly sprayed out through the through hole of the drain trough 14, allowing the condensate to soak the heat dissipation absorbent cotton 15 covering the outer surface of the compressor 8. The heat dissipation absorbent cotton 15 evaporates water and takes away the heat of the compressor 8. With the use of the cooling fan 11, the evaporation speed of the heat dissipation absorbent cotton 15 is accelerated, so that the compressor 8 can maintain a stable temperature and ensure the stable operation of the compressor 8 and the air source heat pump.

[0042] A maintenance plate 17 is fixedly installed on the outer surface of the main frame 1 near the heat dissipation and water absorption cotton 15, and the main frame 1, compressor 8 and maintenance plate 17 are connected. The main frame 1 and water-repellent sound-absorbing cotton 10 are bound together.

[0043] When the internal components of the main frame 1 are damaged and need to be inspected and maintained, the inspection plate 17 can be removed from the main frame 1, which facilitates the inspection and maintenance of the internal components of the main frame 1. The binding design of the main frame 1 and the water-repellent sound-absorbing cotton 10 makes it easy to disassemble and install the water-repellent sound-absorbing cotton 10, which facilitates the inspection and maintenance of the internal components of the main frame 1.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
