Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an assembly structure for an evaporator assembly and an air conditioner. Background Technology

[0002] In air conditioning systems, the evaporator is the core component that enables heat exchange between the refrigerant and the air, and its performance directly affects the efficiency and operational stability of the entire system. V-type evaporators, due to their compact structure and high heat exchange capacity, are widely used in residential air conditioners. However, as users increasingly demand easier installation, lighter weight, and greater overall structural reliability for residential floor-standing air conditioners, the traditional V-type evaporator and its assembly structure have gradually revealed some shortcomings.

[0003] Traditional V-shaped evaporators consist of two heat exchangers joined together and secured by a fixing device. This V-shaped evaporator is mounted on a drain device, and its sides are fixed to the assembly structure using screws. The assembly structure is then secured to the air conditioner using screws and other fasteners. The assembly process for this V-shaped evaporator is relatively complex, increasing installation time and labor costs, and hindering later maintenance and replacement. Secondly, the drain device is usually a separate component, lacking structural integration with the evaporator body, resulting in a less compact overall structure, occupying more space, and hindering the miniaturization of air conditioners. Furthermore, the assembly structure of this V-shaped evaporator relies heavily on screws and other fasteners, leading to loosening and inconvenient disassembly, affecting the stability and reliability of the air conditioning product during transportation and use. Utility Model Content

[0004] Based on this, one of the objectives of this utility model is to provide an assembly structure for an evaporator assembly. By integrating the water receiving tray and the support and fastening structure of the evaporator into a single design, the overall structure is simplified and the space utilization is improved, solving the problems of the evaporator being difficult to fix, heavy, and complex to assemble during the transportation of household air conditioners.

[0005] Another objective of this utility model is to provide an air conditioner with an assembly structure for the evaporator assembly, which has strong structural stability and reliability, helps to achieve the purpose of lightweighting and easy handling of the air conditioner, and effectively improves the manufacturing efficiency and performance of the air conditioner product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Furthermore, the assembly structure of the evaporator assembly also includes a top cover, the lower surface of which is provided with a positioning groove, and the top of the evaporator assembly is inserted into the positioning groove.

[0009] Furthermore, the assembly structure of the evaporator assembly also includes at least two connectors, one end of which is fixedly connected to the water receiving tray and the other end of which is fixedly connected to the top cover.

[0013] Furthermore, the first reinforcing rib is a fan-shaped reinforcing rib, and the second reinforcing rib is a triangular reinforcing rib, a rhomboid reinforcing rib, a grid-like reinforcing rib, a corrugated reinforcing rib, or a honeycomb reinforcing rib.

[0014] Furthermore, the water receiving tray includes a first tray bottom that is horizontally arranged and a second tray bottom that is inclined, with a drain hole provided at the bottom of the first tray; the bottom of the second tray bottom is connected to the bottom of the first tray.

[0015] Furthermore, the evaporator assembly includes a V-shaped evaporator.

[0016] On the other hand, this utility model also provides an air conditioner, including the assembly structure of the above-mentioned evaporator assembly.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) By setting a boss on the water receiving tray and setting baffles on both sides of the boss in the length direction, a positioning groove for fixing the bottom of the evaporator assembly is formed. By inserting the evaporator assembly into the positioning groove, the evaporator assembly and the drainage fixing assembly can be quickly assembled and positioned, so that the boss can completely and effectively support and fix the heat exchanger assembly, thereby realizing the integrated function of drainage, support and fastening, and thus simplifying the overall structure and improving space utilization.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] In the description of this utility model, it should be noted that the terms "upper," "lower," "bottom," "top," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Existing V-type evaporators typically employ a split or multi-point fixing method, resulting in a complex assembly process. This not only increases installation time and labor costs but also hinders subsequent maintenance and replacement. Secondly, to meet the condensate drainage requirements during evaporator operation, the drainage device is often a separate component, lacking structural integration with the evaporator body. This leads to a less compact overall structure, occupying more space and hindering the miniaturization of air conditioning units. Furthermore, traditional assembly structures often rely on fasteners such as screws for connection, which are prone to loosening and inconvenient to disassemble and assemble, affecting the stability and reliability of the product during transportation and use.

[0038] Based on this, this utility model proposes a novel evaporator assembly structure. By integrating the drainage device with the evaporator's support and fastening structure into a single drainage fixing component, the overall structure is simplified and space utilization is improved. The assembly efficiency and aesthetics are enhanced by using a screwless V-shaped clamping top cover fixing component and drainage fixing component. Sheet metal connectors firmly connect the top cover fixing component and drainage fixing component, forming a unified assembly unit, thus strengthening the structural stability and reliability. This novel evaporator assembly structure not only achieves lightweighting and ease of handling but also effectively improves product manufacturing efficiency and performance, demonstrating promising application prospects and promotional value.

[0039] Please see Figure 1-3The evaporator assembly structure provided in this embodiment includes an evaporator assembly 10 and a drain fixing assembly 20, with the drain fixing assembly 20 located below the evaporator assembly 10. The drain fixing assembly 20 includes a drip tray 22 for draining condensate from the evaporator assembly 10. A boss 24 is provided on the upper surface of the drip tray 22, extending along the bottom shape of the evaporator assembly 10 to support it. Baffles 26 extending along the bottom shape of the evaporator assembly 10 are provided on both sides of the boss 24, and each baffle 26 has a drain outlet 28. The baffles 26 can abut against the evaporator assembly 10 in multiple horizontal directions to fix the evaporator assembly 10 horizontally relative to the drain fixing assembly 20.

[0040] Compared to the existing technology that uses screws and other fasteners to connect the evaporator to the assembly structure and sets up an independent drainage component, this embodiment sets a boss 24 on the water receiving tray 22 and sets baffles 26 on both sides of the boss 24 to form a positioning groove for fixing the bottom of the evaporator assembly 10. By inserting the evaporator assembly 10 into the positioning groove, the evaporator assembly 10 and the drainage fixing component 20 can be quickly assembled and positioned, so that the boss 24 can completely and effectively support and fix the heat exchanger assembly 10. At the same time, a drain hole 28 is set on the baffle 26, so that the condensate flowing down the heat exchanger assembly 10 enters the water receiving tray 22 through the drain hole 28, thereby guiding the condensate and allowing the condensate to be discharged in time.

[0041] Specifically, the evaporator assembly 10 includes a V-shaped evaporator with a certain spring-like shape and an outward-facing opening. The V-shaped evaporator includes a first vertical section 12, a second vertical section 14, and a bent section 16 connecting the first vertical section 12 and the second vertical section 14. The larger the included angle between the first vertical section 12 and the second vertical section 14, the closer the V-shaped evaporator is to a straight-vent type. Too large or too small an included angle will affect the airflow and heat exchange efficiency of the V-shaped evaporator. To achieve better heat exchange efficiency and structural space utilization, the included angle between the two sides of the V-shaped structure of the V-shaped evaporator is preferably 90°-160°. In this embodiment, the opening direction of the V-shaped evaporator is used as the front side of the drainage fixing assembly 20.

[0042] Please see Figure 4The drip tray 22 includes a first tray bottom 222 and a second tray bottom 224. The first tray bottom 222 extends along the horizontal plane and has a drain hole 223 for connecting a drain pipe, so that the condensate in the drip tray 22 can be discharged in a timely manner. The second tray bottom 224 forms an angle with the first tray bottom 222, and its bottom is connected to the first tray bottom 222. Preferably, the angle between the second tray bottom 224 and the horizontal plane is greater than 1° to ensure smooth drainage of condensate and avoid liquid accumulation. In this embodiment, the overall dimensions of the drainage fixing component 20 are 506×140.5×80mm. The bottom 222 of the first tray is located on the left side of the drainage fixing component 20, with a length of 140.5mm and a width of 70mm. The bottom 224 of the second tray is located on the right side of the drainage component 20, with a length of 436mm and a width of 140.5mm. That is, the bottom edge of the bottom 224 of the second tray is connected to the long side of the left side of the bottom 222 of the first tray. The height difference between the top and bottom of the bottom 224 of the second tray is greater than or equal to 6mm.

[0043] Please see Figure 3 Boss 24 is a continuous, uninterrupted V-shaped structure; or, please refer to Figure 5 The boss 24 includes multiple boss segments spaced apart along the bottom shape of the evaporator assembly 10, forming an intermittent V-shaped structure. In a preferred embodiment, the boss 24 includes a first boss segment 242 extending along a first vertical segment 12 and a second boss segment 244 extending along a second vertical segment 14. The first boss segment 242 and the second boss segment 244 are V-shaped. Compared to a continuous boss 24, the V-shaped boss 24 facilitates the assembly of the bent section 16 of the V-shaped evaporator, thereby improving assembly efficiency. Since the V-shaped evaporator itself has a certain degree of resilience, the boss 24 of this invention can be adapted to V-shaped evaporators of various specifications and angles.

[0044] The height of the boss 24 is greater than or equal to 28mm to support the evaporator assembly 10 and prevent the bottom fins of the evaporator assembly 10 from contacting the water receiving pan 22 or being immersed in condensate, which would affect the heat exchange effect. The side of the boss 24 is inclined at a certain angle so that the condensate generated during the operation of the evaporator assembly 10 can flow smoothly down the inclined side of the boss 24 through the drain 28, thereby guiding the condensate flow and reducing water flow noise. Preferably, the inclination angle of the side of the boss 24 relative to the vertical plane is 5°-30°, preferably 10°, which provides a good flow guiding effect and noise reduction effect, improving the user experience.

[0045] The baffle 26 is a continuous baffle with several drain holes 28 at its bottom. Preferably, the height of the drain holes 28 is greater than or equal to 8 mm. Alternatively, the baffle 26 includes multiple baffle segments 262 arranged at intervals along the length of the boss 24, with drain holes 28 formed between adjacent baffle segments 262. Preferably, the height of the baffle 26 is greater than or equal to 20 mm to effectively clamp and fix the V-shaped evaporator, ensuring its stability during operation.

[0046] Furthermore, the sides of the boss 24 and the outer sides of the baffle 26 are provided with multiple first reinforcing ribs 27. The first reinforcing ribs 27 are offset from the drain outlets 28 and are aligned with the drainage direction to ensure smooth drainage and avoid water accumulation. Preferably, the first reinforcing ribs 27 are fan-shaped reinforcing ribs, with their two straight edges connected to the sides of the boss 24 and the outer sides of the baffle 26, respectively, to enhance the structural strength of the baffle 26 and prevent deformation due to prolonged operation. In this embodiment, the two sides of the boss 24 are provided with six drain outlets 28 and six fan-shaped reinforcing ribs, respectively. The fan-shaped reinforcing ribs are located between two adjacent drain outlets 28 and on the outer side of all drain outlets 28, so that the condensate discharged from the drain outlets 28 does not spread to the left or right, but flows directly along the inclined side of the boss 24 to the bottom, further improving drainage efficiency and system reliability.

[0047] The evaporator assembly also includes a top cover fixing assembly 30 and a connecting assembly 40. (See also...) Figure 1 and Figure 7-8 The top cover fixing assembly 30 includes a top cover 32. The lower surface of the top cover 32 forms a positioning groove 36 for the evaporator assembly 10 through a protrusion 34. The top of the evaporator assembly 10 is inserted into the positioning groove 36. The evaporator assembly 10 is limited by the cooperation of the top cover 32 and the drain fixing assembly 20.

[0048] Please see Figure 9 The connecting component 40 includes at least two connecting pieces 42, which are arranged along the length of the drainage fixing component 20, and their two ends are respectively connected to the top cover fixing component 30 and the drainage fixing component 40. The connecting pieces 40 are limited and fixed by the drainage fixing component 20 and the top cover fixing component 30. Through the cooperation of the three, the evaporator component is stably installed, thereby improving the overall stability and assembly reliability of the evaporator assembly structure.

[0049] The drip tray 22 and the top cover 32 have at least two corners that are symmetrically arranged vertically, that is, the projections of at least two drip tray corners 226 and at least two top cover corners 322 on the horizontal plane overlap. The connector 42 is a sheet metal connector with an L-shaped cross-section, one end of which is connected to the outer side of the drip tray corner 226, and the other end is connected to the outer side of the top cover corner 322 that is directly connected to the drip tray corner 226.

[0050] In this embodiment, the water receiving tray 22 and the top cover 32 are rectangular or rectangular, and their projections on the horizontal plane overlap, meaning that the outer peripheries of the water receiving tray 22 and the top cover 32 are arranged symmetrically from top to bottom to achieve structural coordination and unity. One end of each of the two connectors 42 is connected to the first water receiving tray corner 226a and the second water receiving tray corner 226b, respectively, and the other end is connected to the first top cover corner 322a and the second top cover corner 322b, respectively. The first water receiving tray corner 226a and the first top cover corner 322a are directly opposite each other, and the second water receiving tray corner 226b and the second top cover corner 322b are directly opposite each other. The first water receiving tray corner 226a and the second water receiving tray corner 226b are two corners on the rear side of the water receiving tray 22; or, they are two corners on the diagonal of the water receiving tray 22, to enhance the stability of the assembly structure.

[0051] In other embodiments, one end of the three connectors 42 is connected to any three water tray corners 226 of the water tray 22, and the other end is connected to the three top cover corners 322 directly opposite the three water tray corners 226; or, one end of the four connectors 42 is connected to the four water tray corners 226, and the other end is connected to the four top cover corners 322.

[0052] Specifically, please refer to Figure 9 The L-shaped connector 42 has a through hole 424 at each end of its first side 422 and a cut 428 at each end of its second side 426. The outer side of the water tray corner 226 is provided with a screw hole 44 that mates with the through hole 424 and a snap fastener 46 that mates with the cut 428. The outer side of the top cover corner 322 is provided with a screw hole 44 that mates with the through hole 424 and a snap fastener 46 that mates with the cut 428. By engaging the notches 428 at both ends of the connector 42 with the clips 46 located at the corners 226 and 322 of the top cover, respectively, and then connecting the through holes 424 at both ends of the connector 42 with the screw holes 44 at the corners 226 and 322 of the top cover, respectively, the connector 42, the water tray 22, and the top cover 32 are fixed together using screws. This method reduces the amount of screws and other fasteners used and improves assembly efficiency. In this embodiment, the clips 46 are sheet metal clips with a width of 11mm, a height of 10mm, and a recess depth of 7.8mm, used for limiting the fit of the sheet metal connector. The screws are 4×12mm pointed screws, and the screw holes have a sealing structure to prevent condensate from leaking from the fixing parts. This design not only improves the stability and sealing of the overall structure, but also complements the top cover of the evaporator to achieve the limiting function of the sheet metal, reduce the number of screws used, thereby reducing the weight of the whole machine and optimizing assembly efficiency.

[0053] Further, please refer to Figure 7-8The positioning groove 36 has second reinforcing ribs 38 on both sides and the upper surface of the top cover 32 for further reinforcement and fixation. The second reinforcing ribs 38 can be triangular, diamond-shaped, mesh-like, corrugated, or honeycomb-shaped. In this embodiment, the second reinforcing rib 38 is a diamond-shaped rib to enhance overall strength and support the four folded edges, ensuring structural integrity under external loads. This design not only improves the load-bearing capacity of the top cover but also helps to distribute stress and prevent local deformation or breakage.

[0054] Please see Figure 8-9 The outer surfaces of the drip tray 22 and the top cover 32 are also provided with multiple snap-fit ​​structures 52 and multiple threaded holes 54, which are used to fix the evaporator assembly structure to the inside of the air conditioner. This achieves efficient fixing, stable support, and smooth drainage of the evaporator assembly 10 inside the air conditioner, thereby improving the overall system reliability and optimizing the assembly process, showing good engineering application prospects. In this embodiment, the snap-fit ​​structures 52 and threaded holes 54 are spaced apart along the length of the drip tray 22 and located on the rear side of the drip tray 22. The snap-fit ​​structures 52 have snap holes, and the snap holes of the snap-fit ​​structures 52 on the drip tray 22 and the snap-fit ​​structures 52 on the top cover 32 are opened in opposite directions, both away from the evaporator assembly 10.

[0055] In some embodiments, the drainage fixing assembly 20 and the top cover fixing assembly 30 are made of ABS material, which has good corrosion resistance and structural strength, and is suitable for equipment such as household cabinet air conditioners. They are designed to achieve stable installation of the evaporator assembly and, in conjunction with the drainage fixing device, limit and fix the sheet metal connectors, thereby improving the overall structural stability and assembly reliability.

[0056] The assembly method of the evaporator assembly structure provided in this embodiment is as follows: Insert the bottom of the V-shaped evaporator into the positioning groove formed by the baffle 26 on the water receiving tray 22. Then align the positioning groove 36 formed by the protrusion 34 on the top cover 32 with the top of the V-shaped evaporator. The protrusion 34 on the top cover 32 and the baffle 26 on the water receiving tray 22 cooperate to clamp the V-shaped evaporator, preventing it from moving horizontally. Then, engage the cutouts 428 at both ends of the connector 42 with the clips 46 on the water receiving tray 22 and the top cover 32 respectively, forming a limiting fit between the drainage fixing component, the top cover fixing component, and the connecting component. Finally, securely connect the connector 42 to the water receiving tray 22 and the top cover 32 with screws, so that the drainage fixing component, the top cover fixing component, and the connecting component form a complete assembly unit. This effectively prevents the V-shaped evaporator from falling off during transportation, installation, and operation, improving the safety and stability of the overall system.

[0057] Due to the specific geometric shape and resilience of the V-shaped evaporator, it cannot move horizontally in the assembly method of this embodiment, thus achieving effective positioning control. During long-term placement or operation, the V-shaped evaporator may gradually rebound due to material properties, tending towards a square structure. During this process, the baffles on the boss and the protrusions on the top cover will apply clamping force to the V-shaped evaporator, keeping it in a stable clamping state. This achieves the triple functions of fastening, supporting, and positioning the V-shaped evaporator, ensuring its stability and safety during operation.

[0058] In actual production, the drainage fixing components, evaporator components, top cover fixing components and connecting components can be pre-assembled in sequence to form modular components, which are then installed into the whole machine, simplifying the assembly process and improving assembly efficiency.

[0059] This utility model also provides an air conditioner, which includes the above-described evaporator assembly structure. The evaporator assembly structure in this embodiment can have the same structure and achieve the same effect as the evaporator assembly structure in the above embodiments, and will not be described again in this embodiment. In this embodiment, the opening of the V-shaped evaporator faces the air inlet or air outlet of the air conditioner.

[0060] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0061] (1) By setting a boss on the water receiving tray and setting baffles on both sides of the boss in the length direction, a positioning groove for fixing the bottom of the evaporator assembly is formed. By inserting the evaporator assembly into the positioning groove, the evaporator assembly and the drainage fixing assembly can be quickly assembled and positioned, so that the boss can completely and effectively support and fix the heat exchanger assembly, thereby realizing the integrated function of drainage, support and fastening, and thus simplifying the overall structure and improving space utilization.

[0062] (2) By setting a drain on the baffle, the condensate flowing down the heat exchanger assembly enters the water receiving pan through the drain hole, thereby guiding the condensate and allowing it to be discharged in a timely manner.

[0063] (3) By setting reinforcing ribs connecting the baffle and the boss, the structural strength of the baffle is enhanced, and its deformation due to long-term operation is avoided. At the same time, the baffle can guide the condensate and reduce its lateral diffusion.

[0064] (4) By setting a positioning groove on the top cover, the top of the evaporator assembly is positioned for assembly, thereby strengthening the fixing effect of the evaporator assembly. At the same time, by setting reinforcing ribs on the upper surface of the top cover and on both sides of the positioning groove, the structural strength of the top cover and the fixing effect of the evaporator assembly are enhanced. The top cover has good mechanical properties and assembly adaptability in its structural design.

[0065] (5) By setting sheet metal connectors and buckles on the drip tray and top cover to cooperate with the sheet metal connectors, the drip tray and top cover form a matching limit, which together constrains and positions the sheet metal connectors. The two are firmly connected by screws, so that the top cover device and the drip tray device are combined into a complete structural unit, thereby effectively preventing the evaporator from falling off during transportation, installation and operation, and improving the safety and stability of the overall system.

[0066] In summary, the evaporator assembly structure provided by this utility model effectively solves problems such as unstable evaporator fixation, poor drainage, and water flow noise while reducing the overall weight of household cabinet air conditioners, significantly improving product performance and user experience. More importantly, this assembly structure has good scalability and process adaptability, facilitating pre-assembly operations on the production line, increasing production capacity, and shortening the overall assembly cycle, thus demonstrating significant economic benefits and industrial promotion value.

[0067] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
