Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0024] In existing technologies, conventional pool heat pump units typically consist of components such as a front panel, protective mesh, inlet plate, top cover, and chassis. Among these, the front panel not only serves a structural function but is also a key component reflecting the product's aesthetic appeal. Due to varying design requirements, the shape of the front panel differs significantly, often directly impacting the overall structural layout of the unit. To balance airflow performance with design freedom, some designs independently house the air guide ring internally, allowing the front panel to focus on aesthetics while the air guide ring handles airflow guidance. Meanwhile, the compressor chamber, as the installation area for critical components, directly affects the stability and safety of the unit's operation due to its sealing and protective performance.

[0025] Existing pool heat pump units have a water accumulation hazard in their enclosure structure: rainwater easily accumulates in the sealed structure, leading to corrosion of internal components or electrical short circuits. In traditional designs, the sealed cavity lacks an effective drainage path, causing rainwater to stagnate in the gap between the chassis and the structure for extended periods. This results in corrosion of metal parts, decreased electrical insulation performance, and even short circuit failures, severely impacting the equipment's operational reliability and lifespan.

[0026] Based on this, the present invention provides a drain outlet on the side wall of the enclosed box and a drain channel at the bottom of the enclosed box to quickly drain the accumulated water.

[0027] Current common designs are mostly based on airflow organization methods with front or side air outlets. Consequently, the sealing and protection solutions for the compressor cavity are also limited, typically requiring customized designs based on the specific air outlet configuration and external structure. This results in poor structural versatility, long development cycles, and high costs. Furthermore, variations in appearance are often constrained by the adaptation requirements of the internal structure, making it difficult to achieve greater freedom in industrial design.

[0028] Therefore, a versatile and widely applicable chassis structure is needed to effectively achieve comprehensive sealing and safety protection of the compressor cavity without relying on a specific appearance, while being compatible with different air outlet methods (such as front air outlet, side air outlet, etc.), improving the overall operational reliability, and providing greater flexibility and innovation space for the appearance design of pool heat pump units.

[0029] According to an embodiment of this utility model, a surround-type chassis structure is provided, combined with... Figures 1 to 12 As shown, the enclosure includes a chassis 2, a top cover 5, and multiple side panels, which together form a closed enclosure. The chassis 2 is provided with at least one drainage channel 24 and at least one drainage hole 21, and at least one side panel is provided with a drainage outlet 11. The drainage outlet 11 communicates with the drainage channel 24, and the drainage channel 24 communicates with the drainage hole 21. The drainage hole 21 leads to the outside of the closed enclosure.

[0030] The aforementioned surround-type chassis structure, through the interconnected design of the drain outlet 11, drain channel 24, and drain hole 21, can effectively drain rainwater accumulated inside the enclosed chassis, preventing water stagnation from causing corrosion of internal components or electrical short circuits; the smooth drainage path reduces the residue of rainwater in the gap between the chassis 2 and the structure, reducing the risk of metal component corrosion; it significantly improves the operational reliability and service life of the equipment, and solves the problem of water accumulation hazards in traditional sealed chassis.

[0031] In some embodiments, the drain outlet 11 is located at the bottom of the side panel. The drain outlet 11 at the bottom of the side panel allows rainwater to collect and drain away, further reducing water accumulation.

[0032] In some embodiments, four side panels are provided, namely a front side panel, a rear side panel, a left side panel and a right side panel. A partition 10 is provided between the front side panel and the rear side panel. The partition 10 divides the internal cavity space of the enclosed box into a fan cavity and a compressor cavity, which can separate different functional components and reduce mutual interference during operation.

[0033] The front panel includes an air guide ring 1 and a first baffle plate 3; the rear panel includes a rear protective net 6 and a second baffle plate 7; the left side panel is a left protective net 8; and the right side panel is a sprue plate 4. The air guide ring 1, left protective net 8, rear protective net 6, partition plate 10, chassis 2, and top cover 5 together form the fan cavity. The first baffle plate 3, sprue plate 4, second baffle plate 7, partition plate 10, chassis 2, and top cover 5 together form the compressor cavity. Each side panel adopts a dedicated structural design to adapt to the functional requirements of its corresponding cavity.

[0034] The left protective net 8 and the rear protective net 6 are integrally connected, and the second baffle plate 7 and the sprue plate 4 are integrally connected. The left side of the air guide ring 1 is directly and firmly connected to the left protective net 8 with screws, forming an integrated airflow guiding barrier. This structure effectively blocks the path of airflow leakage from the side during fan operation, ensuring that the airflow flows in the predetermined direction, thereby guaranteeing heat exchange efficiency and stable overall performance. This integrated air guide-protective net structure not only enhances aerodynamic performance but also improves structural strength and protection level.

[0035] This embodiment achieves multiple optimizations in structural sealing, drainage capacity, assembly convenience, and airflow control performance through the coordinated design of the air guide ring 1, left protective net 8, and rear protective net 6. It is suitable for swimming pool heat pump units with various appearances and has wide applicability and good engineering application prospects.

[0036] In some embodiments, the drain outlet 11 is provided on the air guide ring 1, and the drain channel 24 and drain hole 21 are provided on the chassis 2 corresponding to the fan cavity, thereby setting the drain channel 24 in the fan cavity, avoiding the drain path from passing through the compressor cavity, reducing the impact on sensitive electrical components, and improving the safety of equipment operation; the partitioned drainage design further optimizes the waterproof performance inside the chassis and enhances the equipment's adaptability to the outdoor environment.

[0037] In this embodiment, a drain outlet 11 is provided at the bottom of the air guide ring 1. The drain outlet 11 maintains a certain distance from the first windbreak plate 3 and the chassis 2, forming a sealed but flow-guiding structural space. This design provides greater freedom in the overall machine shape and meets the needs of different functional layouts. Under extreme weather conditions, rainwater may accumulate in the cavity between the chassis and the sealed structure, affecting the safe operation of the unit. Therefore, this embodiment... Figure 6 A drain outlet 11 is added at the location shown to direct accumulated water towards the fan cavity area; Figure 5 As shown, since the fan cavity is equipped with drainage channels 24 and drainage holes 21, accumulated water can be effectively discharged, avoiding corrosion or electrical safety hazards caused by internal water accumulation. This embodiment achieves passive drainage function in a closed structure by setting drainage paths in critical transition areas, improving the reliability of the unit in harsh environments.

[0038] In some embodiments, the chassis 2 is provided with a bent side plate 22 that protrudes outward and extends upward relative to the air guide ring 1 and the first wind baffle 3. The bent side plate 22 forms a collecting channel 23 with the air guide ring 1 and the first wind baffle 3 respectively, and the collecting channel 23 is connected to the drain outlet 11.

[0039] In this embodiment, the collecting channel 23 can effectively collect rainwater from the gaps between the chassis 2, the air guide ring 1, and the first wind deflector 3, and can also collect rainwater falling downwards from the air guide ring 1 and the first wind deflector 3, preventing rainwater from dispersing and remaining to form water accumulation dead zones. The collecting channel 23 guides rainwater to flow directionally towards the drain outlet 11, enhancing the concentration and smoothness of the drainage path; further improving the efficiency of rainwater collection and discharge inside the chassis, reducing the risk of water accumulation corroding equipment components, and enhancing the overall waterproof protection capability.

[0040] In some embodiments, a connecting plate 9 is provided at the junction of the air guide ring 1 and the first wind deflector 3. The connecting plate 9 includes a connecting plate body 91 and a pressure plate 92. The pressure plate 92 is connected to the connecting plate body 91 and forms a limiting step on the outer wall surface of the connecting plate body 91. A pressing plate 31 is provided on the inner side of the first wind deflector 3. The pressing plate 31 abuts against the outer side of the pressure plate 92 and is connected to the pressure plate 92. The outer wall of the first wind deflector 3 is flush with the outer wall of the connecting plate body 91.

[0041] In this embodiment, the outer wall of the first windbreak plate 3 is flush with the outer wall of the connecting plate body 91 through the cooperation of the limiting step and the pressure plate, thus optimizing the flatness and aesthetics of the chassis appearance. At the same time, a sealing surface is formed between the pressure plate 31 and the pressure plate 92, which enhances the sealing performance at the junction, effectively preventing rainwater from seeping into the internal cavity from the gaps, and further improving the waterproof protection capability of the chassis.

[0042] The left side of the first wind deflector adopts a composite process design of "first pressing the plate, then setting the clips". The key to this design is that the clip structure is formed after the edge pressing process is completed, so that the clip 32 is hidden inside the pressed plate 31, forming a reverse embedded assembly structure. When the first wind deflector 3 is installed with the air guide ring 1, the clip 32 and the locking hole 921 achieve a closed connection, and there are no exposed gaps on the outside. Compared with the traditional open clip assembly method, this structure significantly improves the airtightness of the connection area, effectively preventing external pollutants such as insects and dust from entering the unit, especially avoiding electrical short circuits or component damage caused by the intrusion of small insects, and improving the operational reliability of the equipment in complex outdoor environments.

[0043] In some embodiments, a plurality of buckles 32 are provided at intervals on the inner sidewall of the pressure plate 31, and a plurality of buckle holes 921 corresponding to the buckles 32 are provided at intervals on the pressure plate 92. A plurality of corresponding threaded holes are provided on the pressure plate 31 and the pressure plate 92 respectively. The pressure plate 31 and the pressure plate 92 are connected by buckles 32 and then by screws.

[0044] In this embodiment, the clamping plate 31 and the clamping plate 92 are fixed by a double fixing method of snap-fit ​​connection and screw connection. The snap-fit ​​connection can realize quick positioning and initial fixing, improving assembly efficiency; the screw connection further enhances the connection strength and stability, preventing loosening during long-term use; the double fixing structure effectively improves the sealing performance at the junction, preventing rainwater from seeping in from the connection gap; at the same time, it facilitates later maintenance and disassembly, reduces the difficulty of maintenance, and takes into account both installation convenience and structural reliability.

[0045] like Figure 9 As shown, in this embodiment, the air guide ring 1 and the first wind baffle 3 adopt a composite assembly method of "upper screw fixing + lower three-point buckle connection", which significantly reduces the assembly complexity, improves production efficiency, and ensures structural stability.

[0046] In some embodiments, the connection plate body 91 includes a first plate body 911, a second plate body 912 and a third plate body 913. The outer side wall of the first plate body 911 is flush with the outer side wall of the wind guide ring 1, the second plate body 912 and the third plate body 913 are arranged on the inner side wall of the first plate body 911, the pressure plate 92 is connected with the third plate body 913, a positioning groove 915 with an opening facing inward is formed between the first plate body 911, the second plate body 912 and the third plate body 913, and the partition plate 10 is arranged in the positioning groove 915.

[0047] In this embodiment, the connection plate body 91 forms the positioning groove 915 through the first plate body 911, the second plate body 912 and the third plate body 913, which can realize precise embedding and positioning of the partition plate 10, and improve the accuracy of dividing the internal cavity of the chassis and the structural integrity; the enclosing structure of the positioning groove enhances the connection sealing performance between the partition plate and the connection plate, effectively preventing rainwater from seeping into the fan cavity or the compressor cavity from the gap; at the same time, the assembly process is simplified, and the alignment difficulty of partition plate installation is reduced.

[0048] As Figure 12 shown, a "几"-shaped bending structure is provided on the right side of the wind guide ring 1, and on this basis, the sheet metal edge extends upward to make its height flush with the partition plate. Wherein, the "几"-shaped bending structure is formed by bending the first plate body 911, the second plate body 912, the third plate body 913 and the pressure plate 92. This design enables the wind guide ring and the middle partition plate to be closely attached at the top, forming a continuous physical partition, effectively separating the compressor cavity and the fan cavity, preventing airflow crosstalk, and ensuring the rationality of the internal airflow organization of the unit and the operation stability.

[0049] More specifically, the positioning groove 915 is a U-shaped groove, and the U-shaped groove is adapted to the wall surface of the partition plate 10.

[0050] In some embodiments, as Figure 12 shown, the top end surfaces of the connection plate body 91 and the partition plate 10 are flush with the top end surface of the first wind deflector 3. The top of the first wind deflector also maintains the same height reference as the middle partition plate and the wind guide ring, ensuring the flatness and sealing continuity of the entire rear structure in the vertical direction.

[0051] Further, as Figure 11 shown, the first wind deflector adopts a multi-point cooperative fixing method as a whole: the left side is connected to the wind guide ring 1 through a combination of a buckle and a screw, and the right side of the first wind deflector is firmly fixed to the water gap plate 4 through a screw. This assembly solution closely connects the left protective net 8, the rear protective net 6, the wind guide ring 1, the first wind deflector 3, the water gap plate 4, and the second wind deflector 7, to jointly form a complete and continuous surrounding sealed box structure.

[0052] This sealing structure is independent of the external design and is not limited by airflow patterns such as front or side exhaust, making it highly versatile and widely applicable to various swimming pool heat pump units. Its integrated, modular structure not only enhances the protection performance of the compressor chamber (including dustproof, waterproof, explosion-proof, and noise reduction) but also simplifies the production and assembly process, enhancing product maintainability and platform scalability.

[0053] This embodiment optimizes the structural design and assembly method of the wind deflector, achieving a high level of sealing protection while ensuring convenient installation. It solves the long-standing problem of foreign object intrusion that has plagued the industry, providing strong support for the reliability and design freedom of swimming pool heat pump units.

[0054] To avoid potential risks arising from direct contact between the top cover and the air guide ring 1 and the baffle plate, such as structural resonance and noise amplification due to vibration, and short circuits or corrosion caused by condensate dripping from the inner surface of the top cover onto electrical components, this embodiment provides a sealing element 51 at a corresponding position on the inner side of the top cover. A sealing element 51 is also provided at the junction of the top cover 5 and the side plate. The sealing element 51 can be a sponge or other structure, serving as a buffer and sealing layer. Through the coordinated action of the sealing element 51 on the top cover 5 with the air guide ring and the baffle plate, effective isolation between the compressor chamber and the fan chamber is achieved, while simultaneously resolving the issues of condensate dripping and structural resonance. The sponge is preferably made of PE material, which has good elasticity, waterproofness, and weather resistance, maintaining stable performance throughout the entire life cycle of the unit. By combining structurally matched materials with functional sealing materials, a dual protection mechanism of "hard sealing + soft protection" is achieved, improving the unit's environmental adaptability, safety, and user experience.

[0055] In summary, this utility model, through its wraparound box structure design and integrated functional construction, achieves efficient collaborative processing of multiple conflicting objectives under the premise of adaptability to complex environments, and breaks through the limitation of traditional designs where the internal structure depends on the appearance.

[0056] Specifically, a closed and orderly internal protective cavity is constructed through the surrounding box structure formed by the air guide ring, wind baffle, and middle partition. This physically isolates the compressor cavity from the fan cavity while providing a unified structural standard for drainage paths, snap-fit ​​connections, and top cover sealing. Based on this, a passive drainage channel is embedded into the top drain port of the sealed cavity, and combined with a reverse-formed press-fit structure, achieving integrated functionality of "dustproof sealing—automatic drainage—rapid assembly" without adding extra parts.

[0057] Crucially, this design breaks free from the constraints of traditional solutions where the internal structure is limited by the external appearance, creating a universal internal architecture that can adapt to various air outlet configurations (front, side, etc.) and external shapes. Regardless of changes in the external sheet metal, the core sealing and drainage logic remains consistent, greatly improving platform reusability and product development efficiency.

[0058] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
