Description

Technical Field

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

[0002] An air source heat pump is a highly efficient heating / cooling device that utilizes air heat energy. It absorbs low-grade heat energy from the air through an evaporator, compresses it into high-temperature heat energy through a compressor, and then transfers the heat through a condenser to provide heating and domestic hot water. It boasts high efficiency and energy savings, eliminates the combustion process, is environmentally friendly and low-carbon, and can meet diverse needs with a single unit. Installation does not rely on gas or centralized heating networks. The air source heat pump's filter can filter dust, hair, and particulate matter from the air, preventing them from entering core components such as the evaporator and compressor, thus preventing blockages or wear, reducing the risk of malfunction, and ensuring smooth airflow so that the heat pump can fully absorb heat energy from the air, avoiding efficiency reduction and increased energy consumption due to airflow obstruction.

[0003] In air source heat pumps with quick-disassembly filters, fine dust and hair can easily adhere to the filter surface, forming a dust film. This increases airflow resistance, requiring higher power to draw in air and leading to increased energy consumption. If the blockage is left untreated for a long time, the evaporator temperature will drop too low, causing frost and ice to form. The compressor will need to be started and stopped frequently for defrosting, which not only further increases energy consumption but also shortens the compressor's lifespan due to overload operation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an air source heat pump with a quickly detachable filter, comprising a body, a fan mounted on the surface of the body, a flow guide provided on the surface of the body, a dust filter mounted on the surface of the flow guide, the dust filter including a coarse screen component, the surface of the coarse screen component contacting the surface of the flow guide, a vibrating screen component installed inside the coarse screen component, a support component provided on the surface of the vibrating screen component, the vibrating screen component including a screen and a moving magnet, a dust baffle plate, a fixed magnet and a convex key fixedly connected to the outer surface of the screen, and a return spring fixedly connected to the surface of the convex key. The coarse screen component initially intercepts larger particulate impurities in the air, completing the first stage of purification, while the vibrating screen component performs fine filtration of fine impurities.

[0005] Preferably, the flow guide includes a grille component, the surface of which contacts the inner wall of the body, and a connecting component is mounted on the surface of the grille component.

[0006] Preferably, the grille component includes a grille plate, a guide plate is fixedly connected to the inner wall of the grille plate, a baffle is fixedly connected to the outer surface of the guide plate, and the outer surface of the grille plate is movably connected to the inner wall of the machine body.

This avoids a single filter carrying multiple impurities at the same time, which can lead to rapid clogging. The filter has an active vibration function, which can shake off the attached dust and lint in real time to prevent impurities from getting stuck in the mesh.

[0012] (ii) This air source heat pump with a quick-release filter allows for the rapid removal of the dust filter components through simple plugging and unplugging. Even non-professional users can complete the process independently. The convenient disassembly and assembly design allows users to clean the clogged filter in a timely manner, avoiding problems such as airflow obstruction and energy efficiency reduction caused by long-term accumulation of impurities. At the same time, it reduces the labor costs caused by cumbersome maintenance.

[0013] (III) This air source heat pump with a quick-release filter reduces filter clogging, maintains stable airflow, ensures full air contact with the evaporator, prevents dust film formation, ensures heat exchange efficiency, reduces the extra load on the fan and compressor, reduces power consumption, and the multiple filtration prevents impurities from entering the equipment, avoiding fan blade wear, compressor jamming and other malfunctions, indirectly extending the overall service life of the equipment and reducing maintenance costs and downtime losses caused by clogging.

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.

[0017] Example 1, please refer to Figure 1 , Figure 2 This utility model provides an air source heat pump with a quickly detachable filter, including a body 1. A fan 4 is installed on the surface of the body 1. A guide vane 2 is provided on the surface of the body 1. A dust filter 3 is installed on the surface of the guide vane 2. The dust filter 3 includes a coarse screen component 31. The surface of the coarse screen component 31 is in contact with the surface of the guide vane 2. A vibrating screen component 32 is installed inside the coarse screen component 31. A support component 33 is provided on the surface of the vibrating screen component 32. The vibrating screen component 32 includes a screen 321 and a moving magnet 323. A dust baffle 322, a fixed magnet 324, and a convex key 325 are fixedly connected to the outer surface of the screen 321. A return spring 326 is fixedly connected to the surface of the convex key 325. When the fan 4 installed on the surface of the body 1 is started, it provides power for the airflow and guides the external air to move towards the body 1. The guide vane 2 on the surface of the body 1 plays a guiding role, accurately guiding the flowing air to the dust filter 3 installed on its surface, ensuring that the airflow enters the filtration stage stably.

[0018] Example 2, please refer to Figures 3 to 6Based on Embodiment 1, this utility model provides a technical solution: the flow guide 2 includes a grid component 21, the surface of which contacts the inner wall of the body 1, a connecting component 22 is installed on the surface of the grid component 21, the grid component 21 includes a grid plate 211, a flow guide plate 212 is fixedly connected to the inner wall of the grid plate 211, a baffle 213 is fixedly connected to the outer surface of the flow guide plate 212, the outer surface of the grid plate 211 is movably connected to the inner wall of the body 1, the connecting component 22 includes an outward expansion spring 221 and a T-key 226, a circular block 225 is fixedly connected to the outer surface of the outward expansion spring 221 and the T-key 226, the outer surface of the circular block 225 slides against the inner wall of the grid plate 211, an expansion post 224 is fixedly connected to the end of the outward expansion spring 221, a sliding post 223 is slidably connected to the inner wall of the expansion post 224, and the end of the sliding post 223... A central spring 222 is fixedly connected to the part, and the end of the central spring 222 is fixed to the inner wall of the circular block 225. When the fan 4 guides the external air into the machine body 1, the guide plate 212 fixedly connected to the inner wall of the grid plate 211 will guide the airflow in an orderly manner to avoid the decrease in air intake efficiency caused by airflow turbulence and ensure that the air flows accurately to the dust filter 3. The baffle 213 fixedly connected to the outer surface of the guide plate 212 can intercept large impurities such as leaves and plastic fragments in advance to prevent them from directly impacting the screen 321 of the dust filter 3. The outer surface of the circular block 225 slides and adapts to the inner wall of the grid plate 211, and its position can be adjusted with the installation action. The outward expansion spring 221 fixed on the circular block 225 will push the expansion column 224 at the end to extend outward, and the sliding column 223 slidably connected to the inner wall of the expansion column 224 will assist the expansion column 224 to return to its original position under the elastic action of the central spring 222.

[0019] Example 3, please refer to Figures 7 to 10Based on embodiments 1-2, this utility model provides a technical solution: the coarse screening component 31 includes a frame 311, the surface of which is provided with column grooves 312, T-shaped grooves 313 and dust holes 315. The inner wall of the column groove 312 slides against the outer surface of the expanding column 224, the inner wall of the T-shaped groove 313 slides against the outer surface of the T-shaped key 226, the coarse screening plate 314 is fixedly connected to the inner wall of the frame 311, the outer surface of the frame 311 is movably connected to the outer surface of the grid plate 211, the outer surfaces of the screen 321 and the dust baffle 322 are slidably connected to the inner wall of the frame 311, the outer surfaces of the moving magnet 323 and the protruding key 325 slide against the inner wall of the frame 311, the outer surface of the fixed magnet 324 is fixed to the inner wall of the frame 311, and a return spring 326 is provided.

A sliding rod 333 is slidably connected to the inner wall of the hollow rod 332. The end of the sliding rod 333 is fixed to the outer surface of the screen 321. The moving magnet 323 on the outer surface of the screen 321 and the fixed magnet 324 fixed to the inner wall of the frame 311 generate an interaction force, such as a repulsive force. Combined with the elastic reset action of the reset spring 326 fixed to the surface of the key 325, the screen 321 is driven to slide and vibrate at high frequency along the inner wall of the frame 311. This can shake off the dust and lint attached to the mesh of the screen 321 in time, prevent impurities from getting stuck in the mesh, and significantly improve the anti-clogging efficiency.

[0020] The working principle of this air source heat pump with a quick-release filter is described in detail below: In use, the fan 4 on the surface of the machine body 1 is activated to guide external air in. The air first flows through the grille component 21 of the guide plate 2, where the guide plate 212 on the inner wall of the grille 211 guides the airflow in an orderly manner. The baffle 213 on the outer surface of the guide plate 212 forms a specific gap with the guide plate 212 through the central circular hole, allowing the airflow to pass through while blocking large impurities such as leaves from entering. Then the airflow enters the dust filter 3 connected to the guide plate 2 through the connecting component 22. First, it passes through the coarse screen plate 314 in the frame 311 of the coarse screen component 31 to intercept hair and large dust particles, and then passes through the screen 321 of the vibrating screen component 32 for fine filtration. The dust baffle 322 prevents impurities from leaking out. The moving magnet 323 interacts with the fixed magnet 324 on the inner wall of the frame 311, and the return spring 326 on the convex key 325 causes the screen 321 to vibrate to avoid clogging. The connecting frame 331, hollow rod 332, and sliding rod 333 of the 33 provide stable support for the vibration of the screen 321. The impurities generated by filtration are discharged through the dust hole 315 of the frame 311. When installing the dust filter 3, the T-key 226 of the connecting component 22 is embedded in the T-groove 313 of the frame 311 and slides up to the top to prevent it from falling off. During the process, the expansion column 224 is squeezed and compressed, and the outer expansion spring 221 and the central spring 222 retract inward. After the T-key 226 is in place, the expansion column 224 is aligned with the column groove 312 of the frame 311 and resets and is embedded under the action of the spring to achieve self-locking and prevent the T-key 226 from sliding. When disassembling, pull out the round block 225 that is fixed with the T-key 226 and the outer expansion spring 221, and drive the expansion column 224 to move backward and slide out of the column groove 312 to release the self-locking. Then the dust filter 3 can be taken out. The entire process realizes the coordinated operation of efficient airflow guidance, graded filtration and anti-clogging, and quick replacement of the dust filter.
