Description

Technical Field

[0001] This application relates to the technical field of water trays, and more particularly to a water tray structure and a heat pump swimming pool device. Background Technology

[0002] In the field of commercial swimming pool equipment technology, fins are key components for achieving core functions such as improved heat exchange efficiency and water flow guidance control. The reliability of their assembly with the water receiving tray directly affects the long-term operating performance of the equipment. In existing technologies, the fixing of fins and water receiving trays generally adopts a pin-fitting positioning structure. Specifically, pin holes are pre-set on the water receiving tray, and matching pins are machined at corresponding positions on the fins. The engagement of the pins with the pin holes achieves rapid positioning and initial fixing of the fins.

[0003] However, this positioning structure has unavoidable technical flaws. Due to the machining dimensional tolerances of the pin and pin hole, assembly operation errors, and the cumulative effect of vibration loads during equipment operation, gaps inevitably form between the mating surfaces of the pin and pin hole. When the pool machine is in operation, the circulating water or condensate inside the equipment can easily leak through these gaps. The leaked water will continuously accumulate in the internal chambers and surrounding areas of the equipment, causing the metal components inside and around the equipment to be in a continuously humid environment for a long time. A long-term humid environment will significantly accelerate the electrochemical and chemical corrosion rates of the metal components. As the corrosion process progresses, the tensile strength, yield strength, and other mechanical properties of the metal components will decrease significantly, making them prone to deformation and cracking. This not only undermines the overall structural integrity of the equipment but also causes malfunctions such as abnormal operating noises and load imbalances, seriously affecting the operational stability and safety of the pool machine, ultimately shortening the equipment's service life and increasing the maintenance costs and operational interruption risks of commercial pools. Utility Model Content

[0004] The purpose of this application is to provide a water receiving tray structure and a heat pump swimming pool device to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On one hand, a water receiving tray structure is provided, including: a first water receiving tray, at least two limiting members, and a fixing member. The first water receiving tray can be used to install two finned heat exchangers. The two limiting members are disposed on one side of the first water receiving tray, and the two limiting members are respectively located at two end corners of the first water receiving tray. The limiting members are used to cooperate with one side of the end plate of the finned heat exchanger for limiting. The fixing member is disposed on the other side of the first water receiving tray, and the fixing member is located on the center line of the first water receiving tray. The fixing member can cooperate with and fix the other side of the end plate of the two finned heat exchangers respectively.

[0006] Furthermore, the first water receiving tray is provided with a hollow hole, and a water receiving groove is provided at the bottom of the first water receiving tray, with the water receiving groove correspondingly located below the hollow hole.

[0007] Furthermore, a fixing plate is detachably installed at the bottom of the water receiving tank, and a clamping space is formed between the bottom surface of the water receiving tank and the fixing plate. The clamping space can be used to install and clamp the electric heating element and the heat preservation component.

[0008] Furthermore, the bottom of the water receiving tank is provided with a connecting part, which is connected to the fixing plate.

[0009] Furthermore, multiple connecting parts are provided, and the multiple connecting parts are arranged in an array at the bottom of the water receiving tank.

[0010] Furthermore, the water receiving trough is welded to the bottom of the first water receiving tray.

[0011] Furthermore, the bottom of the first water receiving tray is also provided with multiple reinforcing components.

[0012] Furthermore, the outer peripheral edge of the first water receiving tray extends upward to form an annular baffle.

[0013] Furthermore, a second water receiving plate protrudes from the top of the first water receiving plate, the vertical projection area of ​​the first water receiving plate covers the second water receiving plate, and the second water receiving plate has multiple holes, which allow the liquid distribution pipe and gas collection pipe of the finned heat exchanger to pass through and be installed. The second water receiving plate is also provided with a flow guiding slope.

[0014] On the other hand, a heat pump swimming pool device is also provided, including a water receiving tray structure as described above, and at least two finned heat exchangers, wherein the two finned heat exchangers are fixedly installed on the first water receiving tray by the limiting member and the fixing member.

[0015] The beneficial effects of this application are as follows: On the one hand, it solves the leakage problem from the root. The first water receiving tray eliminates the traditional positioning slot design, completely eliminating the condensate leakage channel caused by the slot gap, avoiding corrosion problems of internal metal components caused by the humid environment, and ensuring the structural integrity and operational stability of the equipment. On the other hand, taking into account both assembly efficiency and structural simplification, the limiting component can quickly achieve pre-positioning of the finned heat exchanger without the need for additional positioning processes, and a single fixing component can simultaneously fix two heat exchangers. Compared with the traditional multi-fixing-point design, it simplifies the assembly steps and structural complexity, reduces processing and assembly costs, and improves overall assembly efficiency.

[0019] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1-3As shown, this embodiment provides a water receiving tray structure, including: a first water receiving tray 1, at least two limiting members 2, and a fixing member 3. The first water receiving tray 1 can be used to install two finned heat exchangers. The two limiting members 2 are disposed on one side of the first water receiving tray 1, and the two limiting members 2 are respectively located at two end corners of the first water receiving tray 1. The limiting members 2 are used to cooperate with one side of the end plate of the finned heat exchanger for limiting. The fixing member 3 is disposed on the other side of the first water receiving tray 1, and the fixing member 3 is located on the center line of the first water receiving tray 1. The fixing member 3 can cooperate with and fix the other side of the end plate of the two finned heat exchangers respectively.

[0023] Based on the above scheme, precise assembly of the finned heat exchanger is achieved through the coordinated action of regional limiting and fixing. During the finned heat exchanger installation phase, two finned heat exchangers are placed correspondingly in the assembly area of ​​the first water receiving tray 1, ensuring that one side of the end plate of each finned heat exchanger is tightly fitted with the limiting members 2 at the two corners of one side of the first water receiving tray 1. The limiting members 2, through their contact with the side of the end plate, effectively constrain the forward and backward displacement of the finned heat exchanger, quickly completing the pre-positioning of the two finned heat exchangers and ensuring their stable position during subsequent fixing processes. After pre-positioning, fixing members 3, located on the center line of the other side of the first water receiving tray 1, are used to connect with the other side of the end plates of the two finned heat exchangers. Through the fastening action of the fixing members 3 on the end plates, the two finned heat exchangers are simultaneously locked onto the first water receiving tray 1, achieving overall assembly stability.

[0024] Regarding this solution, its effects include: Firstly, compared to the traditional water receiving tray structure with positioning slots, the first water receiving tray 1 of this application does not need to have positioning slots. This eliminates the gap between the slot and the end plate of the finned heat exchanger from the structural design source, preventing condensate from leaking into the equipment through the gap. This design effectively avoids the leakage water from soaking the equipment's interior and surrounding metal components for a long time, fundamentally slowing down the metal corrosion rate, ensuring the mechanical properties of the metal components, and thus maintaining the overall structural integrity and long-term operational stability of the equipment.

[0025] Secondly, the setting of the limiting component 2 can quickly achieve the pre-positioning of the finned heat exchanger in the early stage of assembly, avoiding the offset adjustment of the fins during the assembly process and reducing the auxiliary positioning process; at the same time, a single fixing component 3 can complete the synchronous fixing of two finned heat exchangers. Compared with the traditional method of fixing multiple fixing components 3 separately, it not only simplifies the assembly steps and reduces the complexity of the assembly operation, but also simplifies the structural components of the water receiving tray, reduces the cost input in the processing and manufacturing process, and achieves a dual improvement in assembly efficiency and structural economy.

[0026] Meanwhile, during the assembly of the finned heat exchanger, once one side of the end plate of the two finned heat exchangers is pre-positioned and fitted with the limiting member 2 at the corner of the first water receiving tray 1, and the other side of the end plate is aligned with the fixing member 3 at the center line of the water receiving tray, screws are passed through the pre-set mounting holes of the limiting member 2 and the finned heat exchanger end plate, and the fixing member 3 and the finned heat exchanger end plate, respectively. Tightening the screws forms a tight, rigid connection between the limiting member 2, the fixing member 3, and the end plate. This connection method, through the axial clamping force of the screws, firmly locks the mating surfaces of the limiting member 2 and the end plate, and the fixing member 3 and the end plate, making the three a single force-bearing unit. This not only restricts the displacement of the finned heat exchanger in the front-to-back direction, but also constrains its vertical and horizontal movement, further enhancing the accuracy of assembly positioning and the overall structural integrity.

[0027] Generally, the first water receiving tray 1 has perforated holes 101, and a water receiving groove 4 is provided at the bottom of the first water receiving tray 1. The water receiving groove 4 is correspondingly located below the perforated holes 101. There are multiple perforated holes 101, some of which are symmetrically arranged on the left and right sides of the first water receiving tray 1, and some of which are located on the upper side of the first water receiving tray 1. In the upper left and right parts, there are four water receiving grooves 4, corresponding to the perforated holes 101 in four areas, and the water receiving grooves 4 are connected to each other. Each combination of water receiving grooves 4 has at least one drain outlet 8. The perforated holes 101 distributed in multiple positions can quickly guide the water accumulated in different areas of the surface of the first water receiving tray 1, avoiding local water accumulation and residue. The water receiving grooves 4 arranged in corresponding areas ensure that condensate can be directly collected after passing through the perforated holes 101, reducing the water flow at the bottom of the first water receiving tray 1. Furthermore, the interconnected design of the two water receiving tanks 4 allows for a balanced distribution of water among the tanks, preventing overflow from a single tank 4 due to excessive water volume. Simultaneously, the inclusion of at least one drain outlet 8 provides a stable channel for condensate drainage, preventing drainage failure if the outlet 8 becomes clogged. Overall, this design effectively prevents condensate from accumulating in the first water receiving pan 1 and inside the equipment, further reducing the risk of moisture corrosion to equipment components. It also simplifies the drainage path design, improving the equipment's environmental adaptability and long-term reliability.

[0028] In some embodiments, a fixing plate 5 is detachably installed at the bottom of the water receiving tank 4, forming a clamping space between the bottom surface of the water receiving tank 4 and the fixing plate 5. This clamping space can be used to install and clamp the electric heating element and the insulation component. During the assembly of the water receiving tank 4, the electric heating element and the insulation component are placed at a preset position at the bottom of the water receiving tank 4. Then, the fixing plate 5 is detachably installed at the bottom of the water receiving tank 4, forming a closed clamping space between the bottom surface of the water receiving tank 4 and the fixing plate 5. The size of this clamping space is adapted to the combined thickness of the electric heating element and the insulation component. Through the pressing action of the fixing plate 5 on the insulation component, the insulation component is tightly attached to the surface of the electric heating element, while the electric heating element is also stably confined within the clamping space, achieving synchronous fixation of the electric heating element and the insulation component. When it is necessary to inspect or replace the electric heating element or the insulation component, the fixing plate 5 can be removed to open the clamping space and complete the maintenance operation of the component.

[0029] Compared to traditional adhesive-based fixing methods, this solution uses a clamping space formed by the fixing plate 5 and the water receiving tank 4 to mechanically press the insulation component tightly against the surface of the electric heating element. This avoids the risk of the insulation component falling off due to adhesive failure during equipment vibration or long-term operation, ensuring that the insulation component always remains wrapped around the electric heating element and guaranteeing long-term stable insulation efficiency. Furthermore, the clamping space can limit and fix the electric heating element, preventing displacement or shaking during equipment operation and avoiding impact on heating effect due to component misalignment. Simultaneously, the stable wrapping of the insulation component prevents heat loss from the electric heating element, improving energy utilization efficiency and effectively preventing condenser icing due to excessively low ambient temperatures.

[0030] Specifically, the insulation component can be insulation sponge.

[0031] Specifically, the bottom of the water receiving tank 4 has a protruding connecting part 6, which is connected to the fixing plate 5. When installing the fixing plate 5, the electric heating element and the insulation component are first placed in a preset area at the bottom of the water receiving tank 4. Then, the fixing plate 5 is aligned with the protruding connecting part 6 at the bottom of the water receiving tank 4. The connecting part 6 engages with the corresponding mounting holes on the fixing plate 5, and screws or other fasteners are used to secure the fixing plate 5 to the connecting part 6. The protruding connecting part 6 provides a precise positioning reference and stable connection support for the fixing plate 5, ensuring that the fixing plate 5 remains parallel to the bottom surface of the water receiving tank 4 after installation. This ensures a uniformly sized and pressure-stable clamping space between the two, thereby tightly and evenly clamping and fixing the electric heating element and the insulation component.

[0032] More specifically, multiple connecting parts 6 are provided, and these multiple connecting parts 6 are arranged in an array at the bottom of the water receiving tank 4. Compared with single or scattered connecting parts 6, the array arrangement can ensure that the fastening force on the fixing plate 5 is evenly transmitted along the plate surface, avoiding localized force concentration that could cause deformation of the fixing plate 5. At the same time, it ensures that the bonding pressure between the insulation component and the surface of the electric heating element is consistent throughout, eliminating insulation dead corners caused by localized poor bonding and improving insulation efficiency.

[0033] It is worth noting that the water receiving trough 4 is welded to the bottom of the first water receiving tray 1. During assembly, the water receiving trough 4 is precisely positioned at the preset installation position on the bottom of the first water receiving tray 1, and the connection part 6 of the two is welded and fixed using a multi-point spot welding process. During welding, the high temperature causes the connection interface between the water receiving trough 4 and the first water receiving tray 1 to fuse together, and after cooling, an integral rigid connection structure is formed. At the same time, the sealing interface formed by welding can eliminate the gap at the connection part 6, so that the connection area between the water receiving trough 4 and the first water receiving tray 1 forms a continuous sealing state, preventing condensate from leaking from the connection part 6. The distributed weld points formed by multiple spot welds provide multi-point support at the connection part 6, so that the force is evenly distributed throughout the entire connection area.

[0034] Compared to traditional screw fastening methods, this welding connection method has significant advantages: First, it greatly improves sealing performance. The fusion interface formed by welding eliminates the unavoidable gaps in screw connections, fundamentally blocking the path of condensate leakage from the connection between the water tank 4 and the water tray 6. This further reduces the risk of corrosion of internal metal components due to water accumulation, ensuring the long-term safety of the equipment. Second, it enhances the overall structural strength. The distributed stress structure formed by multiple spot welds makes the connection strength between the water tank 4 and the water tray more uniform, effectively resisting the stress generated by vibration, impact, and temperature changes during equipment operation. This significantly improves the overall deformation resistance of the water tray and reduces component failures caused by structural deformation. Third, it simplifies structural design. It eliminates the need for additional screws, nuts, and other fastening components, reducing the number of parts and assembly steps, and avoiding maintenance problems caused by loose or corroded fasteners, thus improving the reliability and economy of the structure.

[0035] Meanwhile, multiple reinforcing members 9 are also provided at the bottom of the first water receiving tray 1. The reinforcing members 9 are fixed to the bottom of the water receiving tray in a preset layout, forming an integrated load-bearing structure with the main body of the first water receiving tray 1. During equipment operation, when the first water receiving tray 1 bears the weight of the finned heat exchanger, the pressure of the internal water, and vibration loads, the multiple reinforcing members 9 can distribute the concentrated stress to different areas at the bottom of the first water receiving tray 1, resisting the bending or deformation tendency of the first water receiving tray 1 through their own rigid support, ensuring that the main body of the first water receiving tray 1 maintains the preset structural shape, and avoiding deformation caused by excessive local stress.

[0036] Preferably, the outer periphery of the first water receiving tray 1 extends upward to form an annular baffle 102. The annular baffle 102 is continuously arranged along the outer periphery of the water receiving tray, forming a surrounding barrier structure. When condensation or accumulated water is present on the surface of the first water receiving tray 1, the baffle 102 can physically prevent water from spreading to the edge and overflowing. Simultaneously, the folded joint of the baffle 102 is sealed using a welding process, eliminating gaps or openings that may exist in traditional folded structures, thus forming a complete and continuous sealed boundary and preventing water leakage along the joint. This combination of upward-extending barrier and welded seal constructs a leak-proof barrier from two dimensions: physical obstruction and gap sealing.

[0037] In one embodiment, a second water receiving tray 7 protrudes from the top of the first water receiving tray 1, and the vertical projected area of ​​the first water receiving tray 1 covers the second water receiving tray 7. The second water receiving tray 7 has multiple holes 701, which allow the liquid distribution pipe and gas collecting pipe of the finned heat exchanger to pass through and be installed. The second water receiving tray 7 also has a guide slope. The multiple holes 701 on the second water receiving tray 7 correspond to the positions of the liquid distribution pipe and gas collecting pipe of the finned heat exchanger, allowing the aforementioned pipes to pass through and be installed, thus achieving the assembly and positioning of the pipes and the water receiving tray. There is a height difference between the plane of the second water receiving tray 7 and the reference plane of the first water receiving tray 1, and the surface of the second water receiving tray 7 has a guide slope. When condensate generated during equipment operation falls onto the surface of the second water receiving tray 7, it flows naturally along the guide slope. Using the gravitational potential energy formed by the height difference, the water flows towards the first water receiving tray 1, eventually converging into the water collection area of ​​the first water receiving tray 1, and then draining into the water receiving tank 4 through the perforated holes 101. At the same time, the vertical projection area of ​​the first water receiving tray 1 covers the second water receiving tray 7, which can form a bottom catch to receive water that may overflow from the edge of the second water receiving tray 7.

[0038] On the other hand, a heat pump swimming pool device is also provided, including the water receiving tray structure as described above, and at least two finned heat exchangers, the two finned heat exchangers being fixedly installed on the first water receiving tray 1 by the limiting member 2 and the fixing member 3.
