Description

Technical Field

[0001] This utility model relates to the technical field of air source heat pump equipment, and in particular to an air source heat pump that is easy to maintain. Background Technology

[0002] An air source heat pump is a device that uses the reverse Carnot cycle principle to extract low-grade heat energy from the air and convert it into high-grade heat energy. It is widely used in heating, cooling and hot water supply systems in homes and industries. Compared with traditional electric heating or fossil fuel heating methods, air source heat pumps have significant advantages such as high efficiency, energy saving and environmental protection without pollution. Therefore, in today's world where energy shortages and environmental problems are becoming increasingly serious, they have received more and more attention and application.

[0003] Although air source heat pump technology is relatively mature, its maintenance still faces some challenges in actual use. Traditional air source heat pump units usually adopt a relatively fixed structural design, with the door panel connected to the unit body by screws or other fixing devices. While this design can ensure the stability and sealing of the unit, it also brings inconvenience to daily maintenance. When it is necessary to inspect, clean or replace internal components, operators need to spend a lot of time disassembling and reinstalling the door panel, which not only increases maintenance costs but also prolongs downtime and affects the operating efficiency of the equipment.

[0004] In view of the above problems, there is an urgent need for an air source heat pump that is easy to maintain. Summary of the Invention

[0005] In order to overcome the shortcomings of traditional air source heat pump units, where the door panel is connected to the unit body by screws or other fixing devices, resulting in inconvenient daily maintenance, increased maintenance costs and downtime, this utility model provides an air source heat pump that is easy to maintain.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an easy-to-maintain air source heat pump, comprising an air source heat pump unit, a door panel on the front side of the air source heat pump unit, limit frames slidably mounted on both sides of the air source heat pump unit, symmetrically distributed L-shaped connecting blocks fixed to the rear side of the door panel, a telescopic cylinder at the upper middle position of the air source heat pump unit, and a sliding rod slidably connected to each end of the telescopic cylinder, the sliding rods being connected to adjacent limit frames respectively to form a linkage mechanism.

[0007] As an improvement to the above solution, the air source heat pump unit is equipped with symmetrically distributed jet pipes that rotate inside. One end of each jet pipe extends out of the air source heat pump unit and is connected to a gas delivery pipe, which is connected to a gas pump.

[0008] As an improvement to the above solution, the air source heat pump unit is fixedly connected to symmetrically distributed support seats on its side. Each support seat is equipped with a motor. The output shaft of the motor is connected to a first missing gear via a key. A second missing gear that meshes with the first missing gear is installed at one end of the jet pipe near the motor. A spiral spring is sleeved on the jet pipe. One end of the spiral spring is fixedly connected to the second missing gear, and the other end is fixedly connected to the outer wall of the air source heat pump unit.

[0009] As an improvement to the above solution, the air source heat pump unit has rotating shafts installed inside on both sides. Each rotating shaft has an L-shaped clamping plate rotatably mounted on it. A torsion spring is sleeved on the rotating shaft. The two ends of the torsion spring are respectively connected to the L-shaped clamping plate and the interior of the air source heat pump unit. A rotating rod is fixedly connected to the L-shaped clamping plate. A pulling frame is rotatably mounted on the rotating rod. A pedal is slidably mounted on the lower part of the air source heat pump unit. The upper end of the pedal is slidably connected to the pulling frame, and the lower end of the pedal extends out of the air source heat pump unit.

[0010] As an improvement to the above solution, a toolbox is slidably installed in the upper part of the air source heat pump unit.

[0011] As an improvement to the above solution, the toolbox is equipped with multiple storage compartments.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. Through the linkage design of the limiting frame, sliding rod and L-shaped connecting block, the disassembly and assembly process of the door panel can be simplified without the use of tools, realizing the quick disassembly and assembly of the door panel, reducing maintenance time and labor intensity, greatly improving the convenience and efficiency of maintenance, and providing users with a better user experience.

[0013] 2. By combining the jet assembly and the drive assembly, the jet assembly provides efficient cleaning and heat dissipation, while the drive assembly enables precise angle adjustment to meet the needs of different operating conditions, thereby significantly improving the maintenance convenience and working efficiency of the air source heat pump unit.

[0014] 3. Through the combined design of pivot, L-shaped clamp, rotating rod, pulling frame, torsion spring and pedal, not only is the safety of the door panel when it is released from its fixed position guaranteed, but the door panel is also kept stable when not in use, preventing accidental opening or loosening.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1: Please refer to Figure 1 and Figure 2 An easy-to-maintain air source heat pump includes an air source heat pump unit 1. The air source heat pump unit 1 has a door panel 2 on its front side. Limiting frames 3 are slidably installed on both the left and right sides of the air source heat pump unit 1. L-shaped connecting blocks 4 are welded to the rear side of the door panel 2, and the L-shaped connecting blocks 4 are engaged with the limiting frames 3 on both sides to fix the door panel 2. A telescopic cylinder 5 is installed in the middle of the upper part of the air source heat pump unit 1. A sliding rod 6 is slidably connected to each of the left and right ends of the telescopic cylinder 5. The sliding rod 6 is connected to the adjacent limiting frames 3 to form a linkage mechanism.

[0024] When maintenance is required, the operator can push the two sliding rods 6 outwards. Due to the connection between the sliding rods 6 and the limiting brackets 3, the two limiting brackets 3 move inwards synchronously. As the limiting brackets 3 move, they are released from the L-shaped connecting blocks 4 on the door panel 2, thereby releasing the fixation on the door panel 2. At this time, the door panel 2 is no longer restricted and can be easily removed from the air source heat pump unit 1 for inspection of internal components. After maintenance is completed, simply place the door panel 2 back in the correct position, ensuring that the L-shaped connecting blocks 4 are aligned with the limiting brackets 3, and then push the sliding rods 6 outwards to allow the limiting brackets 3 to re-engage in the L-shaped connecting blocks 4, thus re-fixing the door panel 2 and restoring the closed state of the equipment.

[0025] Example 2: Based on Example 1, please refer to... Figure 3 The air source heat pump unit 1 is equipped with symmetrically distributed jet pipes 8 inside. The jet pipes 8 are rotatable to achieve more uniform gas distribution or directional blowing effect. One end of each jet pipe 8 extends out of the air source heat pump unit 1 and is connected to a gas delivery pipe 7. The gas delivery pipes 7 are all connected to an air pump 9.

[0026] When internal cleaning or heat dissipation operations are required, the air pump 9 is started. The air pump 9 supplies compressed air or other gases to each jet pipe 8 through the air supply pipe 7. The compressed gas is sprayed into the designated area inside the air source heat pump unit 1 through the jet pipe 8. The high-pressure gas can effectively remove dust and dirt from the surface of internal components, maintain heat exchange efficiency, or increase internal air circulation to help quickly reduce the internal temperature. Especially when working in high-temperature environments, it helps to improve the stability and lifespan of the equipment. After the operation is completed, the air pump 9 is turned off, and the gas pressure in the jet pipe 8 gradually disappears.

[0027] Please see Figure 3 and Figure 4 The air source heat pump unit 1 has symmetrically distributed support bases 10 fixed to its left side. Each support base 10 is equipped with a motor 11. The output shaft of the motor 11 is connected to a first missing gear 12 via a key. A second missing gear 13 is installed at the end of the jet pipe 8 near the motor 11, which meshes with the first missing gear 12. The engagement of the second missing gear 13 with the first missing gear 12 enables the motor 11 to drive the jet pipe 8 to rotate. A spiral spring 14 is sleeved on the jet pipe 8. One end of the spiral spring 14 is fixedly connected to the second missing gear 13, and the other end is fixedly connected to the outer wall of the air source heat pump unit 1, providing a restoring force for the jet pipe 8.

[0028] When the angle of the jet pipe 8 needs to be adjusted, the motor 11 is started. The output shaft of the motor 11 drives the first misaligned gear 12 connected to it to rotate. The first misaligned gear 12 meshes with the second misaligned gear 13 on the jet pipe 8. As the first misaligned gear 12 rotates, the second misaligned gear 13 rotates accordingly, thereby driving the jet pipe 8 to rotate. The spiral spring 14 deforms, thereby adjusting the rotation angle and jet direction of the jet pipe 8, realizing multi-angle and multi-level blowing operations, thus significantly increasing the coverage of cleaning or heat dissipation and improving work efficiency. When the first misaligned gear 12 rotates to a specific angle, it will temporarily disengage from the second misaligned gear 13. At this time, the restoring force of the spiral spring 14 will cause the jet pipe 8 to return to the initial position for operation. This process is repeated to ensure the cleaning or heat dissipation effect.

[0029] Please see Figure 5 and Figure 6 The air source heat pump unit 1 has rotating shafts 1501 installed inside on both sides. Each rotating shaft 1501 has an L-shaped clamping plate 15 rotatably mounted on it to hold the door panel 2. A torsion spring 17 is sleeved on the rotating shaft 1501. The two ends of the torsion spring 17 are connected to the L-shaped clamping plate 15 and the interior of the air source heat pump unit 1, respectively. The function of the torsion spring 17 is to provide a restoring force so that the L-shaped clamping plate 15 remains in the state of holding the door panel 2 when no external force is applied. A rotating rod 1601 is fixedly connected to the L-shaped clamping plate 15. A pull frame 16 is rotatably mounted on the rotating rod 1601. The pull frame 16 can rotate freely on the rotating rod 1601 to adapt to different operating angles. A foot pedal 18 is slidably mounted at the bottom of the air source heat pump unit 1. The upper end of the foot pedal 18 is slidably connected to the pull frame 16. The lower end of the foot pedal 18 extends out of the air source heat pump unit 1 for workers to step on.

[0030] When maintenance is required, first release the limit bracket 3 from fixing the door panel 2. However, the L-shaped clamp 15 still holds the door panel 2 in place to prevent it from falling suddenly. This design ensures the safety of the operator and prepares for subsequent steps. Next, the operator steps on the pedal 18 to move it downwards. As the pedal 18 moves downwards, the pull bracket 16 is moved inwards. Under the pulling force of the pull bracket 16, the rotating rod 1601 drives the L-shaped clamp 15 to rotate around the rotating shaft 1501. The torsion spring 17 deforms accordingly. As the L-shaped clamp 15 rotates, the door panel 2 is no longer restricted by the clamp and can be easily removed for internal maintenance. After maintenance, the door panel 2 is placed back in the correct position, the pedal 18 is released, and the L-shaped clamp 15 automatically resets under the action of the torsion spring 17, locking the door panel 2 again to enhance its stability and ensure that the door panel 2 is stably fixed in the non-working state, preventing accidental opening or loosening.

[0031] Please see Figure 5The air source heat pump unit 1 has a tool box 19 that is slidably installed in the upper part. The tool box 19 has two storage compartments 20 inside. The tool box 19 and the storage compartments 20 are designed to store tools and parts of different sizes. In addition, the sliding design allows them to be easily pulled out and pushed back, which not only saves space but also makes it convenient for operators to quickly access and store tools and parts.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
