Description

Technical Field

[0001] This utility model relates to the field of air source heat pumps, specifically a high-efficiency air source heat pump. Background Technology

[0002] Air source heat pumps are high-efficiency and energy-saving hot water and heating equipment. Their working principle is based on the reverse Carnot cycle, absorbing heat from the air to produce hot water, meeting the demand for large-volume, high-pressure, and constant-temperature hot and cold water 24 hours a day. This equipment has a wide range of applications, including domestic heating, commercial water heaters, agricultural drying, industrial heating and cooling, and constant-temperature agricultural greenhouses. However, existing air source heat pumps require regular cleaning and replacement of filters, screens, and evaporators to maintain their heating and cooling performance. This process often involves removing multiple bolts to dismantle the side cover or access panel of the heat pump, which, for a pump requiring regular maintenance, reduces the ease of maintenance and increases the workload for operators. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a high-efficiency air source heat pump to solve the technical problems of large maintenance workload and poor maintenance convenience of current air source heat pumps.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency air source heat pump, comprising a unit body, a top cover is rotatably mounted on one side of the top of the unit body via a hinge, a fastener is provided on one side of the top cover, and fasteners are provided on both sides of the unit body. Filter screens are slidably installed on both the front and rear sides of the unit body via sliding grooves, and a fan body is mounted on the top cover.

[0005] By adopting the above technical solution, the operator needs to unlock the latch and latch block to separate the top cover from the main body of the unit. Then, by applying force to the top cover with the handle, it can be rotated around the hinge and opened easily.

[0006] Furthermore, the top cover is engaged with the main body of the unit via a latch and a latching block.

[0007] By adopting the above technical solution, it is ensured that the top cover can be firmly connected to the main body of the unit when closed, thereby effectively preventing the top cover from being accidentally opened during the operation of the unit due to vibration or external force. This not only ensures the safety of the internal components of the unit, but also avoids performance degradation or damage caused by the top cover being opened.

[0008] Furthermore, handles are provided on both sides of the top cover to provide support points for the operator to apply force to the top cover.

[0009] By adopting the above technical solution, when opening or closing the top cover, the operator can easily apply lifting or downward pressure to the top cover by holding the handle, thereby ensuring that the top cover can rotate smoothly, making the operation process simpler and reducing the labor intensity of the operator.

[0010] Furthermore, two sets of evaporators are installed at the top inside the main body of the unit, and a compressor and a condenser are installed at the bottom inside the main body of the unit.

[0011] By adopting the above technical solutions, it is beneficial to make full use of the internal space of the unit and improve the heat exchange efficiency. The evaporator is a key component in the heat pump unit to realize heat energy conversion. The rationality of its layout directly affects the overall performance of the unit. The setting of two sets of evaporators can optimize the airflow organization while ensuring sufficient heat exchange area, so that heat can be distributed and transferred more evenly, thereby improving the heating or cooling effect of the unit.

[0012] Furthermore, an electrical box is installed on one side of the main body of the unit and is electrically connected to an external power source.

[0013] By adopting the above technical solution, the heat pump unit needs to control the switching and adjustment of various electrical components during operation, such as compressors, fans, and sensors. Concentrating these electrical components in the electrical box can not only reduce wiring complexity and lower the failure rate, but also facilitate operators to perform inspection and maintenance.

[0014] Furthermore, a protective cover is fixedly installed on the top of the top cover by a bracket to prevent external debris from falling into the interior of the wind turbine body and the unit body. The top of the protective cover has a pointed conical structure.

[0015] By adopting the above technical solutions, during the operation of the unit, dust, fallen leaves, rainwater and other debris in the surrounding environment may have an adverse effect on the unit, such as clogging the air duct and corroding the parts. The protective cover can effectively prevent these debris from entering, protect the cleanliness and dryness of the unit's interior, and thus extend the unit's service life.

[0016] Furthermore, limit frames are fixedly installed on both sides of the back of the main body of the unit to limit the rotation angle and position of the top cover.

[0017] By adopting the above technical solution, when the operator raises or lowers the top cover by the handle, the limit frame will play a limiting role, preventing the top cover from rotating excessively due to uneven force or improper operation, thereby ensuring a tight and reliable connection between the top cover and the main body of the unit.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model uses a latch, latch block, and handle. The operator needs to unlock the latch and latch block, which is a prerequisite for opening the top cover. After unlocking, the operator applies a lifting force to the top cover using the handle. The rotation of the hinge allows the top cover to be easily lifted. At the same time, the limiting bracket provides support during the opening process of the top cover, ensuring that the top cover remains stably open and providing the operator with sufficient maintenance space. Then, the operator can directly clean the surface of the evaporator inside the main unit through the opening of the top cover. This series of operations replaces the cumbersome steps of disassembling multiple bolts in traditional maintenance, significantly improving the convenience of maintenance.

[0020] 2. This utility model, by setting a protective cover, effectively blocks external dust, fallen leaves, rainwater and other debris, avoiding pollution and damage to the main body of the fan and the inside of the unit. This helps to keep the inside of the unit clean and dry, thereby extending the service life of the unit and improving its operating efficiency. At the same time, the pointed conical structure of the protective cover has excellent flow guiding and drainage performance. In rainy weather, the pointed conical top can quickly guide rainwater to the edge and drain it out, preventing water accumulation from damaging the unit. Attached Figure Description

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] Example 1:

[0032] A high-efficiency air source heat pump, such as Figures 1-5 As shown, the unit includes a main body 1. A top cover 2 is hinged on one side of the top of the main body 1. A latch 602 is provided on one side of the top cover 2. Locks 601 are provided on both sides of the main body 1. Filter screens 4 are slidably installed on the front and rear sides of the main body 1 via sliding grooves 8. A fan body 3 is installed on the top cover 2. The operator needs to unlock the latches 601 and latches 602 to separate the top cover 2 from the main body 1. Then, force is applied to the top cover 2 by the handle 7 to make it rotate around the hinge and open easily. At the same time, it provides sufficient space for maintenance. After the top cover 2 is open, the operator can directly clean the evaporator 501 inside the main body 1 through the opening at the top. Meanwhile, compared with the traditional maintenance method, it saves the tedious steps of disassembling multiple bolts, thus greatly improving the convenience and efficiency of maintenance.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4The top cover 2 is engaged with the main body 1 of the unit via latch 601 and latch block 602, ensuring that the top cover 2 is securely connected to the main body 1 of the unit when closed. This effectively prevents the top cover from being accidentally opened due to vibration or external force during unit operation. This not only ensures the safety of the internal components of the unit but also avoids performance degradation or damage caused by the opening of the top cover 2. At the same time, the engagement of latch 601 and latch block 602 makes the opening and closing process of the top cover 2 simpler and faster. Operators only need to unlock latch 601 to easily open the top cover 2 without disassembling other parts or tools. This not only improves the convenience of maintenance but also reduces the labor intensity of operators.

[0034] See Figure 1 , Figure 2 Handles 7 are provided on both sides of the top cover 2 to provide support points for the operator to exert force on the top cover 2. When opening or closing the top cover 2, the operator can easily apply lifting or downward pressure to the top cover 2 by holding the handles 7, thereby ensuring that the top cover 2 can rotate smoothly, making the operation process simpler and reducing the labor intensity of the operator. At the same time, the design of the handles 7 also improves the safety of operation. During maintenance, the operator needs to frequently open and close the top cover 2. Without the handles 7 as support, the operator may need to directly touch the edge of the top cover 2 or other parts of the unit body 1 with their hands, which may increase the risk of injury.

[0035] See Figure 1 , Figure 2 The unit body 1 has two sets of evaporators 501 located at the top inside, and a compressor 502 and a condenser 503 located at the bottom inside. This arrangement helps to fully utilize the internal space of the unit and improve heat exchange efficiency. The evaporator 501 is a key component in the heat pump unit that realizes heat energy conversion, and its layout directly affects the overall performance of the unit. The arrangement of two sets of evaporators 501 can optimize airflow organization while ensuring sufficient heat exchange area, so that heat can be distributed and transferred more evenly, thereby improving the heating or cooling effect of the unit. At the same time, the compressor 502 and the condenser 503 are arranged at the bottom inside the unit body 1. The compressor 502, as the heart of the heat pump unit, is responsible for driving the refrigerant circulation, and its stable operation is an important guarantee for the performance of the unit. The condenser 503 is responsible for converting the refrigerant from a gaseous state to a liquid state and releasing heat.

[0036] See Figure 4An electrical box 504 is installed on one side of the main body 1 of the heat pump unit and is electrically connected to an external power source. During operation, the heat pump unit needs to control the switching and adjustment of various electrical components, such as the compressor, fan, and sensors. Concentrating these electrical components in the electrical box 504 not only reduces wiring complexity and lowers the failure rate, but also facilitates inspection and maintenance by operators. At the same time, the electrical connection between the electrical box 504 and the external power source ensures that the unit can obtain power stably and reliably. The external power source provides power support for the unit and is the basis for the normal operation of the unit. Through the connection between the electrical box and the external power source, the stable transmission and distribution of electrical energy can be achieved, ensuring the normal operation of various components inside the unit.

[0037] Example 2:

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The top of the top cover 2 is fixedly installed with a protective cover 10 by a bracket to prevent external debris from falling into the interior of the fan body 3 and the unit body 1. The top of the protective cover 10 has a pointed conical structure. During the operation of the unit, dust, fallen leaves, rainwater and other debris in the surrounding environment may have an adverse effect on the unit, such as clogging the air duct and corroding the parts. The protective cover 10 can effectively block the entry of these debris, protect the cleanliness and dryness of the unit's interior, and thus extend the service life of the unit. At the same time, the pointed conical structure of the top of the protective cover 10 is not only aesthetically pleasing, but more importantly, it has excellent air guiding and drainage performance. In rainy weather, the pointed conical top can quickly guide rainwater to the edge and drain it out, avoiding water accumulation that could damage the unit.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Limiting brackets 9 are fixedly installed on both sides of the back of the main body 1 of the unit to limit the rotation angle and position of the top cover 2. When the operator lifts or presses down the top cover 2 through the handle 7, the limiting brackets 9 will play a limiting role to prevent the top cover 2 from rotating excessively due to uneven force or improper operation, thereby ensuring that the connection between the top cover 2 and the main body 1 of the unit is tight and reliable. At the same time, the limiting brackets 9 can also effectively limit the rotation angle of the top cover 2 to ensure that it will not tilt excessively or tip over when it is opened to the maximum position, thus protecting the structural integrity of the top cover 2 and the main body 1 of the unit. The limiting brackets 9 can firmly hold the top cover 2 to prevent it from being accidentally closed or damaged, and keep it in an open state for a long time to facilitate maintenance operations.

[0040] The implementation principle of this utility model is as follows: When the heat pump unit needs to be repaired, firstly, the latch 601 and the latch block 602 are unlocked. Then, the operator applies lifting force to the top cover 2 through the handle 7, causing the top cover 2 to rotate through the hinge. Next, the top cover 2 is supported by the limit bracket 9 to ensure that the top cover 2 is always in the open state. Then, the operator can clean the surface of the evaporator 501 inside the unit body 1 through the opening at the top. At the same time, the filter screen 4 is slid and removed through the slide groove 8, and subsequent cleaning and replacement operations are performed. This method replaces the situation in the traditional maintenance process where multiple bolts need to be removed, improving the convenience of maintenance.

[0041] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
