[0001] This utility model relates to the field of air handling equipment technology, and in particular to a water receiving tray, a heat exchanger assembly, and an air conditioner having the same. Background Technology

[0002] In related technologies, large solid debris or hair that falls into the drip tray can flow with the condensate into the drain hole, easily clogging the drain hole of the air conditioner's drip tray or the pipe that discharges condensate, causing the air conditioner to malfunction. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a water collection tray that prevents large solid pieces, wool, or other debris from flowing into the drain hole along with the condensate, reducing the probability of the drain hole and drain pipe being blocked by debris and ensuring normal drainage from the water collection tray.

[0004] This utility model also proposes a heat exchanger assembly, which includes the aforementioned water receiving tray.

[0005] This utility model also proposes an air conditioner, which includes the heat exchanger assembly described above.

[0006] According to an embodiment of the present invention, a water receiving tray is used in an air conditioner and includes: a water receiving tray body, the water receiving tray body having a water receiving groove, the bottom wall of the water receiving groove being provided with a drain hole and a plurality of barrier posts, the plurality of barrier posts being arranged at intervals in the circumferential direction of the drain hole, and the cross-sectional area of ​​the barrier posts gradually decreasing in the direction from bottom to top.

[0007] According to an embodiment of this utility model, the water receiving tray has drainage holes and multiple baffles on the bottom wall of the water receiving trough. These baffles are spaced apart circumferentially around the drainage holes. The baffles allow condensate to flow between adjacent baffles while blocking large solid objects, wool, or other debris. This prevents such debris from flowing with the condensate into the drainage holes, reducing the probability of blockage and ensuring proper drainage. This reduces the likelihood of air conditioner malfunctions, improves reliability, and enhances the user experience. Furthermore, the cross-sectional area of ​​the baffles gradually decreases from bottom to top, facilitating demolding and simplifying the production of the water receiving tray, thus reducing manufacturing complexity.

[0008] In addition, the water receiving tray according to this utility model may also have the following additional technical features:

[0009] In some embodiments, the plurality of the barrier posts are evenly spaced in the circumferential direction of the drainage holes.

[0011] In some embodiments, the angle between the axis of the barrier post and the outer wall surface of the barrier post is b, and satisfies: 1.5°≤b≤6°.

[0012] In some embodiments, the cross-section of the barrier post is circular, and the diameter of the upper end of the barrier post is c, satisfying: 1.5mm≤c≤4mm.

[0013] In some embodiments, the height of the barrier post is d, and satisfies: 8mm≤d≤16mm.

[0014] In some embodiments, the water receiving trough is provided with a water-blocking rib plate, which extends along the circumferential direction of the water receiving tray body.

[0018] According to the heat exchanger assembly of this utility model, by providing the aforementioned water receiving tray, and by having drain holes and multiple baffles on the bottom wall of the water receiving tank, the multiple baffles are spaced apart in the circumferential direction of the drain holes. The arrangement of the multiple baffles allows condensate to flow between adjacent baffles while blocking large solid objects, wool, or other debris, preventing these objects from flowing with the condensate into the drain holes. This reduces the probability of the drain holes and drain pipes being blocked by debris, ensuring normal drainage of the water receiving tray, reducing the probability of air conditioner malfunctions, improving the reliability of the air conditioner, and enhancing the user experience. Furthermore, the cross-sectional area of ​​the baffles gradually decreases from bottom to top, facilitating the demolding of the baffles and simplifying the production and processing of the water receiving tray, thus reducing the difficulty of its production.

[0019] In addition, the heat exchanger assembly according to this utility model may also have the following additional technical features:

[0020] In some embodiments, the upper side of the water receiving tray is provided with a buckle assembly, and the lower side of the chassis is provided with a slot that cooperates with the buckle assembly.

[0022] In some embodiments, there are multiple spaced-apart snap-fit ​​components, and multiple slots that correspond one-to-one with each of the multiple snap-fit ​​components.

[0026] In some embodiments, the lower surface of the chassis is provided with an extension post, the drainage hole penetrates the extension post, and the extension post is spaced apart from the second boss in the vertical direction.

[0027] In some embodiments, the distance between the lower end face of the extension post and the upper end face of the second boss is h, and satisfies: 3.5mm≤h≤8mm.

[0028] In some embodiments, there are multiple drainage holes, and the second boss is a plurality of holes corresponding one-to-one with the multiple drainage holes.

[0030] According to the embodiment of this utility model, the air conditioner, by incorporating the aforementioned heat exchanger assembly, features drain holes and multiple baffles on the bottom wall of the water receiving tray. These baffles are spaced apart circumferentially around the drain holes. The arrangement of these baffles allows condensate to flow between adjacent baffles while blocking large solid objects, wool, or other debris. This prevents such debris from flowing with the condensate into the drain holes, reducing the probability of blockage in the drain holes and drain pipes, ensuring proper drainage of the water receiving tray, lowering the probability of air conditioner malfunctions, improving the reliability of the air conditioner, and enhancing the user experience. Furthermore, the cross-sectional area of ​​the baffles gradually decreases from bottom to top, facilitating demolding of the baffles and simplifying the production and processing of the water receiving tray, thus reducing the difficulty of its manufacturing.

[0062] The water receiving tray 2 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0063] like Figure 13 and attached Figure 15 As shown, the water tray 2 according to an embodiment of the present invention is used in an air conditioner 100 and includes a water tray body 26.

[0064] Specifically, see the attached document. Figure 13 and attached Figure 15 As shown, the drip tray 26 has a drip groove 27. The bottom wall of the drip groove 27 is provided with a drain hole 273 and multiple baffles 274. The drain pipe 275 connected to the drip tray 2 is opposite to and communicates with the drain hole 273. The condensate in the drip groove 27 can flow into the drain pipe 275 through the drain hole 273 and finally be discharged outside the air conditioner 100. The multiple baffles 274 are arranged at intervals in the circumferential direction of the drain hole 273. The arrangement of the multiple baffles 274 allows the condensate to flow between two adjacent baffles 274 and blocks large solids or wool and other debris, preventing large solids or wool and other debris in the drip groove 27 from flowing into the drain hole 273 with the condensate. This reduces the probability of the drain hole 273 and the drain pipe 275 being blocked by debris, ensures normal drainage of the drip tray 2, reduces the probability of air conditioner 100 failure, improves the reliability of air conditioner 100, and improves the user experience.

[0065] Further, see Appendix Figure 16 As shown, the lower end of the barrier post 274 is connected to the bottom wall of the water receiving tank 27, in the direction from bottom to top (e.g. Figure 16As shown, the cross-sectional area of ​​the barrier post 274 gradually decreases, which facilitates the demolding of the barrier post 274 and the production and processing of the drip tray 2, reducing the difficulty of production and processing of the drip tray 2. It should be noted that the cross-section of the barrier post 274 can be circular, quadrilateral, or hexagonal, etc., and no further restrictions are imposed here.

[0066] According to the embodiment of this utility model, the water receiving tray 2 has drainage holes 273 and multiple retaining posts 274 on the bottom wall of the water receiving trough 27. The multiple retaining posts 274 are spaced apart in the circumferential direction of the drainage holes 273. The arrangement of multiple retaining posts 274 allows condensate to flow between adjacent retaining posts 274 and blocks large solid pieces or debris such as wool and hair, preventing large solid pieces or debris in the water receiving trough 27 from flowing with the condensate to the drainage holes 273. This reduces the probability of the drainage holes 273 and the drainage pipe 275 being blocked by debris, ensuring normal drainage of the water receiving tray 2, reducing the probability of air conditioner 100 malfunction, improving the reliability of air conditioner 100, and enhancing the user experience. Furthermore, the cross-sectional area of ​​the retaining posts 274 gradually decreases from bottom to top, which facilitates the demolding of the retaining posts 274, simplifies the production and processing of the water receiving tray 2, and reduces the difficulty of production and processing of the water receiving tray 2.

[0067] In some embodiments of this utility model, reference is made to the appendix. Figure 15 As shown, multiple baffles 274 are evenly spaced in the circumferential direction of the drain hole 273, which can avoid the situation where the gaps between different baffles 274 are different, ensuring the blocking effect of the baffles 274 on large solids or debris such as wool and hair, avoiding different baffles 274 having different interception standards for large solids or debris such as wool and hair, further reducing the probability of the drain hole 273 and drain pipe 275 being blocked by debris, ensuring the normal drainage of the water tray 2, reducing the probability of air conditioner 100 malfunctioning, improving the reliability of air conditioner 100, and improving the user experience.

[0068] In some embodiments of this utility model, reference is made to the appendix. Figure 15As shown, the distance between the axes of two adjacent baffle posts 274 is 'a', and satisfies: 6mm ≤ a ≤ 12mm. On one hand, this prevents the baffle posts 274 from being too densely packed, which could affect the normal flow of condensate, ensuring normal demolding of the baffle posts 274 and reducing the processing difficulty of the drip tray 2. On the other hand, it ensures the baffle posts 274 effectively block large solid objects or debris such as wool and hair, reducing the probability of the drain hole 273 and drain pipe 275 being blocked by debris, ensuring normal drainage of the drip tray 2, reducing the probability of air conditioner 100 malfunctioning, improving the reliability of air conditioner 100, and enhancing the user experience. For example, the distance 'a' between the axes of two adjacent baffle posts 274 can be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, or 12mm. It should be noted that the diameter of the drain hole 273 is i, and a < i, which prevents the drain hole 273 from becoming clogged when two solid impurities flow towards it simultaneously.

[0069] In some embodiments of this utility model, reference is made to the appendix. Figure 16 As shown, the angle between the axis of the barrier post 274 and its outer wall is b, and satisfies: 1.5°≤b≤6°. This facilitates demolding of the barrier post 274, simplifies the production and processing of the drip tray 2, and reduces the difficulty of its production and processing. For example, the angle b between the axis of the barrier post 274 and its outer wall can be 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, or 6°.

[0070] In some embodiments of this utility model, reference is made to the appendix. Figure 16 As shown, the cross-section of the barrier post 274 is circular, and the diameter of the upper end of the barrier post 274 is c, satisfying the condition: 1.5mm ≤ c ≤ 4mm. This design avoids manufacturing problems with the barrier post 274, ensuring the normal production and processing of the drip tray 2. Furthermore, it prevents the barrier post 274 from being too thin and causing injury, reducing assembly difficulty for users, ensuring the structural strength of the barrier post 274, and guaranteeing its proper demolding. For example, the diameter c of the upper end of the barrier post 274 can be 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm.

[0071] In some embodiments of this utility model, reference is made to the appendix. Figure 16As shown, the height of the barrier post 274 is d, and it satisfies the condition: 8mm ≤ d ≤ 16mm. On one hand, this prevents poor blocking effect caused by the barrier post 274 being too low, preventing large solid objects or debris such as wool and hair from flowing directly from the top of the barrier post 274 to the drain hole 273, reducing the probability of the drain hole 273 and drain pipe 275 being blocked by debris, ensuring normal drainage of the drip tray 2, reducing the probability of air conditioner 100 malfunctions, improving the reliability of air conditioner 100, and enhancing the user experience. On the other hand, it facilitates the demolding of the barrier post 274, simplifying the production and processing of the drip tray 2 and reducing the difficulty of its production. For example, the height d of the barrier post 274 can be 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, or 16mm.

[0072] In some embodiments of this utility model, reference is made to the appendix. Figure 13 and attached Figure 14 As shown, a water-receiving trough 27 is provided with a water-blocking rib 28. The water-blocking rib 28 extends along the circumferential direction of the water-receiving pan body 26. The outer wall of the water-blocking rib 28 and the inner wall of the water-receiving trough 27 define a water-blocking area 271. The side of the water-blocking rib 28 away from the water-blocking area 271 defines a water-receiving area 272. The water-receiving area 272 and the water-blocking area 271 are not connected to each other. The drain hole 273 and multiple barrier posts 274 are all provided in the water-receiving area 272 and are spaced apart from the inner wall of the water-blocking rib 28.

[0073] In existing technologies, condensate generated during heat exchanger operation drips onto a drip tray. The inner side of the drip tray's sidewall comes into contact with the cooler condensate, creating a low-temperature surface. Meanwhile, the outer side of the drip tray's sidewall comes into contact with the air inside the air conditioner, forcing condensation to form droplets on the relatively cooler surface. This results in condensation on the outer surface of the drip tray's sidewall. To reduce and prevent condensation, existing technologies often use insulating sponges attached to the outer surface of the drip tray's sidewall. However, this increases the cost of the drip tray and reduces its assembly efficiency.

[0074] Understandably, the condensate generated by the heat exchanger 3 during operation will first fall onto the base 11, and then flow to the water receiving area 272 of the water receiving tray 2 through the drain hole 13 and the slot 12. The baffle plate 28 defines the baffle area 271, separating the condensate in the water receiving area 272 from part of the inner wall of the water receiving trough 27. This prevents the condensate from directly contacting the inner wall of the water receiving trough 27 on the baffle area 271 side, thus preventing condensate from forming on the outer wall of the water receiving tray body 26 on the baffle area 271 side and avoiding condensate dripping onto other parts of the air conditioner 100, ensuring a better user experience. Furthermore, compared to existing technologies, there is no need to attach insulation sponge to the outer wall of the water receiving tray body 26, which reduces the production cost of the water receiving tray 2 and improves the assembly and production efficiency of the water receiving tray 2.

[0075] In a further embodiment of this utility model, reference is made to the appendix. Figure 17 As shown, the height of the water-blocking rib 28 is less than the depth of the water-receiving trough 27, which facilitates the production and processing of the water-receiving tray 2, ensures the normal demolding of the water-receiving tray 2, avoids defects in the side walls of the water-blocking rib 28 and the water-receiving trough 27, and ensures the reliability of the water-receiving tray 2.

[0076] In a further embodiment of this utility model, reference is made to the appendix. Figure 17 As shown, the height of the baffle 28 is f, and it satisfies: 7mm ≤ f ≤ 16mm. On the one hand, ensuring that the height f of the baffle 28 is ≤ 16mm facilitates the production and processing of the water receiving tray 2, preventing the baffle 28 from being too high and affecting the normal demolding of the water receiving tray 2, avoiding defects in the side walls of the baffle 28 and the water receiving trough 27, and ensuring the reliability of the water receiving tray 2; on the other hand, as Figure 13 As shown, the water receiving tank 27 is provided with an overflow hole 29. When the drain hole 273 is blocked, the condensate water level in the water receiving tank 27 rises. When the condensate water level overflows the overflow hole 29, the condensate water in the water receiving tank 27 can be discharged from the overflow hole 29. At this time, the air conditioner 100 is displayed as a fault. By setting the height f of the water-proof rib 28 to ≥ 7mm, the upper end of the water-proof rib 28 can be higher than the overflow hole 29, preventing the condensate water in the water receiving tank 27 from overflowing the water-proof rib 28 and flowing into the water-proof area 271. For example, the height f of the water-proof rib 28 can be 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, or 16mm.

[0077] In a further embodiment of this utility model, reference is made to the appendix. Figure 17As shown, the water-proof zone 271 extends circumferentially along the drip tray body 26. The width of the water-proof zone 271 is g, and it satisfies the following condition: 4mm ≤ g ≤ 10mm. Ensuring that the width g ≥ 4mm maximizes the width of the water-proof zone 271, increasing the distance between the outer wall of the water-proof rib 28 and the inner wall of the drip tray 27, further reducing the probability of condensation on the outer circumferential wall of the drip tray body 26 on the side of the water-proof zone 271, and preventing condensation from dripping onto other parts of the air conditioner 100, thus ensuring a better user experience. Ensuring that the width g ≤ 10mm prevents the water-proof zone 271 from being too wide, thus preventing condensation on the chassis 11 from dripping directly into the water-proof zone 271, thereby ensuring the effectiveness of the water-proof zone 271. For example, the width g of the water-proof zone 271 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm.

[0078] In a further embodiment of this utility model, a plurality of partition plates are provided in the water-proof zone 271. The partition plates are spaced apart in the circumferential direction of the water receiving tray body 26. The partition plates can strengthen the structure of the water-proof rib plate 28 and support and connect the water-proof rib plate 28 and the side wall of the water receiving trough 27, thereby improving the structural strength and connection strength of the water-proof rib plate 28, improving the reliability of the water-proof rib plate 28, and ensuring the setting of the water-proof zone 271.

[0079] In a further embodiment of this utility model, the water-blocking rib 28 can be one or multiple ribs spaced apart along the circumferential direction of the water receiving tray body 26. It is understood that the water-blocking rib 28 can be one, with its two ends extending in the direction of extension abutting against two spaced points on the front sidewall of the water receiving trough 27. A water-blocking area 271 is defined between the outer wall of the water-blocking rib 28 and the inner wall of the water receiving trough 27. The water-blocking area 271 covers the left, right, and rear ends of the water receiving trough 27, thus better preventing condensation from forming on the outer circumferential wall of the water receiving tray body 26. Alternatively, the water-blocking rib 28 can be multiple ribs spaced apart along the circumferential direction of the water receiving tray body 26, such as... Figure 13 As shown, each water-proof rib 28 defines a water-proof area 271 between itself and the inner wall of the water receiving trough 27. Multiple water-proof areas 271 are spaced apart along the circumferential direction of the water receiving tray body 26. The gap between two adjacent water-proof areas 271 can be used to avoid the drain hole 273 or other features on the water receiving tray 2. For example, the number of water-proof ribs 28 can be one, two, or three.

[0080] In a further embodiment of this utility model, reference is made to the appendix. Figure 15As shown, the minimum distance between the barrier post 274 and the inner wall of the water receiving trough 27 is e1, and the minimum distance between the barrier post 274 and the water-blocking rib plate 28 is e2. When e1 < e2, 5mm ≤ e1 ≤ 11mm; when e1 > e2, 5mm ≤ e2 ≤ 11mm. This allows the barrier post 274 and the inner wall of the water receiving trough 27 or the water-blocking rib plate 28 to also block large solid objects or debris such as wool and hair. This further reduces the probability of the drain hole 273 and drain pipe 275 being blocked by debris, ensures normal drainage of the water receiving tray 2, reduces the probability of air conditioner 100 malfunctioning, improves the reliability of air conditioner 100, and enhances the user experience.

[0081] It should be noted that when the distance between the drain hole 273 and the inner wall of the water receiving trough 27 or the water-blocking rib plate 28 is relatively large, the barrier posts 274 can be multiple posts that complete a full circumference around the drain hole 273; when the distance between the drain hole 273 and the inner wall of the water receiving trough 27 or the water-blocking rib plate 28 is relatively small, such as Figure 15 As shown, the inner wall of the water receiving trough 27 or the water-blocking rib plate 28 does not need to be additionally equipped with a barrier post 274. The inner wall of the water receiving trough 27 or the water-blocking rib plate 28 can be used to block large solids or debris such as wool and hair, which can relatively reduce the number of barrier posts 274 and reduce the production and processing difficulty of the water receiving tray 2.

[0082] This utility model also proposes a heat exchanger assembly 10 having the water receiving tray 2 of the above embodiment.

[0083] like Figure 4 and Figure 5 As shown, the heat exchanger assembly 10 according to an embodiment of the present invention includes a heat exchanger bracket 1 and the aforementioned water receiving tray 2.

[0084] Specifically, see the attached document. Figure 5 As shown, the lower end of the heat exchanger bracket 1 has a base 11. The heat exchanger 3 is mounted on the base 11 and located in front of the heat exchanger bracket 1. As the main heat source device of the air conditioner 100, the heat exchanger 3 can efficiently transfer heat to meet the user's heating needs. The heat exchanger bracket 1 is used to install and support the heat exchanger 3, which can securely install and fix the heat exchanger 3 inside the air conditioner 100. The design of the heat exchanger bracket 1 often takes into account the overall layout and weight distribution of the heat exchanger 3, and can adopt a reasonable structural form to enhance the support effect on the heat exchanger 3 and reduce stress concentration.

[0085] Further, see attached document. Figure 6As shown, the chassis 11 is provided with a drain hole 13, and the water receiving tray 2 is located below the chassis 11 and connected to the chassis 11. When the heat exchanger 3 is working, it will produce condensate. The condensate will first fall onto the chassis 11 and then flow through the drain hole 13 to the water receiving tray 2. The water receiving tray 2 is used to collect the condensate produced when the heat exchanger 3 is working, so as to prevent the condensate on the heat exchanger assembly 10 from flowing to other parts of the air conditioner 100, and to prevent the air conditioner 100 from dripping or the components inside the air conditioner 100 from short-circuiting.

[0086] According to the embodiment of the present invention, the heat exchanger assembly 10 includes a water receiving tray 2, and a drain hole 273 and multiple baffles 274 are provided on the bottom wall of the water receiving trough 27. The baffles 274 are spaced apart in the circumferential direction of the drain hole 273. The arrangement of the baffles 274 allows condensate to flow between adjacent baffles 274 and blocks large solid objects, wool, or other debris, preventing these objects from flowing with the condensate to the drain hole 273. This reduces the probability of the drain hole 273 and drain pipe 275 being blocked by debris, ensuring normal drainage of the water receiving tray 2, reducing the probability of air conditioner 100 malfunctions, improving the reliability of air conditioner 100, and enhancing the user experience. Furthermore, the cross-sectional area of ​​the baffles 274 gradually decreases from bottom to top, facilitating demolding of the baffles 274 and simplifying the production and processing of the water receiving tray 2, thus reducing the difficulty of its production.

[0087] In some embodiments of this utility model, reference is made to the appendix. Figure 10 and attached Figure 13 As shown, the upper side of the water receiving tray 2 is provided with a snap-fit ​​assembly 21, and the lower side of the chassis 11 is provided with a slot 12 that cooperates with the snap-fit ​​assembly 21. The cooperation between the snap-fit ​​assembly 21 and the slot 12 facilitates the disassembly and assembly of the water receiving tray 2, improves the assembly efficiency of the heat exchanger assembly 10, improves the reliability of the cooperation between the water receiving tray 2 and the chassis 11, and makes the water receiving tray 2 less prone to loosening after assembly, thereby improving the user experience.

[0088] In a further embodiment of this utility model, reference is made to the appendix. Figure 8 Appendix Figure 13 and attached Figure 14As shown, the snap-fit ​​assembly 21 includes a mounting base 22, a spring snap 23, and a limiting rib 24. The mounting base 22 is located on the upper side of the water receiving tray 2 and abuts against the lower end face of the chassis 11. The spring snap 23 includes a connecting part 231 and a hook part 232. The lower end of the connecting part 231 is connected to the mounting base 22 and passes through the slot 12. The hook part 232 is connected to the upper end of the connecting part 231 and is located on the upper side of the chassis 11 and is perpendicular to the lower end face of the chassis 11. The upper surfaces of the mounting base 22 abut against the lower surface of the chassis 11, thus restricting the water receiving tray 2 from moving towards the chassis 11. The hook portion 232 abuts against the upper surface of the chassis 11, thus restricting the water receiving tray 2 from moving away from the chassis 11. This restricts the relative position of the chassis 11 and the water receiving tray 2 from both the upper and lower sides of the chassis 11, preventing vertical displacement between the water receiving tray 2 and the heat exchanger bracket 1 after the heat exchanger assembly 10 is assembled. Figure 8 The relative movement on the plate (as shown) ensures the reliability and stability of the connection between the water receiving tray 2 and the heat exchanger bracket 1, avoids shaking of the components inside the air conditioner 100 during transportation, and thus extends the service life of the heat exchanger assembly 10.

[0089] Understandably, the connecting part 231 has a certain deformation capability. When the water receiving tray 2 is assembled onto the chassis 11, the end of the hook part 232 that is away from the connecting part 231 is blocked by the inner wall of the slot 12. The hook part 232, which is blocked by the inner wall of the slot 12, pushes the upper end of the connecting part 231 to move away from the inner wall of the slot 12. The connecting part 231 deforms and moves along the inner wall of the slot 12 with the hook part 232 until the hook part 232 moves to the upper side of the chassis 11. The connecting part 231 is reset and the hook part 232 abuts against the upper surface of the chassis 11.

[0090] Further, see attached document. Figure 7 and attached Figure 14 As shown, the limiting rib plate 24 is provided on the mounting base 22 and spaced apart from the spring buckle 23. The limiting rib plate 24 passes through the slot 12. During the assembly of the water receiving tray 2 and the chassis 11, the setting of the limiting rib plate 24 can play a certain positioning role, making it easier for the buckle assembly 21 to be aligned with the slot 12, thereby reducing the difficulty of the spring buckle 23 and the slot 12 to cooperate.

[0091] In a further embodiment of this utility model, reference is made to the appendix. Figure 7 and attached Figure 14 As shown, the limiting rib plate 24 includes a first plate 241, a second plate 242, and a third plate 243. The first plate 241 and the spring buckle 23 respectively abut against the two inner walls opposite each other in the width direction of the slot 12, allowing movement from the slot 12 in the width direction (see attached diagram). Figure 7The two sides of the clamping assembly 21 and the slot 12 (as shown in the j direction) restrict the relative position of the clamping assembly 21 and the slot 12, preventing relative movement in the width direction of the slot 12 between the water receiving tray 2 and the chassis 11, thereby ensuring the reliability and stability of the connection between the water receiving tray 2 and the heat exchanger bracket 1, preventing the components inside the air conditioner 100 from shaking during transportation, thereby extending the service life of the heat exchanger assembly 10, and the first plate 241 can prevent the connecting part 231 from deforming too much towards the first plate 241 and breaking during the assembly of the water receiving tray 2 and the chassis 11, thus ensuring the service life of the clamping assembly 21.

[0092] Further, see Appendix Figure 7 and attached Figure 14 As shown, the second plate 242 and the third plate 243 are respectively connected to the first plate 241 along its length (see attached diagram). Figure 7 At both ends of the slot 12 (in the direction shown in the diagram), the second plate 242 and the third plate 243 are respectively aligned with the length direction of the slot 12 (see attached diagram). Figure 7 The two inner walls (in the direction shown in k) abut against each other, which can restrict the relative position of the buckle assembly 21 and the slot 12 from both sides of the slot 12 length direction, and prevent relative movement between the water receiving pan 2 and the chassis 11 in the length direction of the slot 12. This ensures the reliability and stability of the connection between the water receiving pan 2 and the heat exchanger bracket 1, and prevents the components inside the air conditioner 100 from shaking during transportation, thereby extending the service life of the heat exchanger assembly 10.

[0093] In a further embodiment of this utility model, reference is made to the appendix. Figure 7 Appendix Figure 8 and attached Figure 14 As shown, the hook portion 232 has a first guide slope 233 on the side opposite to the first plate 241, in the direction from bottom to top (e.g. Figure 8 As shown, the first guide slope 233 is inclined towards the first plate 241, thereby providing a guiding function when assembling the water receiving tray 2 onto the chassis 11. This allows the first guide slope 233 to abut against the inner wall of the slot 12 during assembly, facilitating the insertion of the spring clip 23 and the assembly of the water receiving tray 2 with the heat exchanger bracket 1. It should be noted that the inner wall of the slot 12 moves relative to the first guide slope 233 from its upper end to its lower end, thus enabling the spring clip 23 to engage with the slot 12 gradually.

[0094] Further, see Appendix Figure 7 and attached Figure 14As shown, the upper ends of the second plate 242 and the third plate 243 opposite to the first plate 241 have a second guide slope 244. The second guide slope 244 is inclined towards the first plate 241 from bottom to top, thus providing a guiding function when assembling the water tray 2 onto the chassis 11. This allows the second guide slope 244 to abut against the inner wall of the slot 12 during assembly, facilitating the insertion of the snap-fit ​​assembly 21 and the assembly of the water tray 2 with the heat exchanger bracket 1. It should be noted that the inner wall of the slot 12 moves relative to the second guide slope 244 from its upper end to its lower end, allowing the snap-fit ​​assembly 21 to engage with the slot 12 gradually.

[0095] Furthermore, see the attached document. Figure 11 and attached Figure 12 As shown, the lower end of the inner peripheral wall of the slot 12 has a third guide slope 121. The third guide slope 121 extends along the circumferential direction of the slot 12. In the top-to-bottom direction, the third guide slope 121 is inclined in a direction away from the axis of the slot 12, thereby playing a guiding role when assembling the water receiving tray 2 onto the chassis 11. This allows the spring clip 23 and the limiting rib plate 24 to be guided along the third guide slope 121 during the assembly process, facilitating the assembly of the water receiving tray 2 and the heat exchanger bracket 1. It should be noted that the clip assembly 21 moves relative to the third guide slope 121 and moves from the lower end to the upper end of the third guide slope 121, thereby enabling the clip assembly 21 to gradually engage with the slot 12.

[0096] In a further embodiment of this utility model, reference is made to the appendix. Figure 9 and attached Figure 14 As shown, a first limiting rib 245 is provided on the surface of the limiting rib plate 24 opposite to the inner peripheral wall of the slot 12. The first limiting rib 245 abuts against the inner wall of the slot 12. The setting of the first limiting rib 245 can avoid the limiting rib plate 24 and the inner wall of the slot 12 from directly abutting each other. It can change the surface contact between the limiting rib plate 24 and the inner wall of the slot 12 to the line contact between the first limiting rib 245 and the inner wall of the slot 12, thereby reducing the friction during the assembly of the buckle assembly 21 and the slot 12, and facilitating the assembly of the water receiving tray 2 and the chassis 11.

[0097] Further, see Appendix Figure 9 and attached Figure 14As shown, the upper end of the first limiting rib 245 has a fourth guide slope 246. In the upward direction, the fourth guide slope 246 is inclined away from the inner peripheral wall of the slot 12, thus providing a guiding function when assembling the water tray 2 onto the chassis 11. This allows the fourth guide slope 246 to abut against the inner wall of the slot 12 during assembly, facilitating the insertion of the snap-fit ​​assembly 21 and the assembly of the water tray 2 with the heat exchanger bracket 1. It should be noted that the inner wall of the slot 12 moves relative to the fourth guide slope 246 from its upper end to its lower end, allowing the snap-fit ​​assembly 21 to gradually engage with the slot 12.

[0098] It should be noted that if the first limiting rib 245 is not provided on the limiting rib plate 24, the fourth guide slope 246 is directly provided on the limiting rib plate 24. However, due to the limitation of the thickness of the limiting rib plate 24 itself, it is not conducive to the production and processing of the fourth guide slope 246, resulting in the fourth guide slope 246 being unable to be processed or having a small guiding surface, thereby affecting the guiding effect of the fourth guide slope 246 and hindering the cooperation between the buckle assembly 21 and the slot 12.

[0099] Furthermore, see the attached document. Figure 7 Appendix Figure 8 and attached Figure 11 As shown, a second limiting rib 122 is provided on the inner wall of the slot 12. The second limiting rib 122 abuts against the limiting rib plate 24. The setting of the second limiting rib 122 can prevent the inner wall of the slot 12 from directly abutting against the limiting rib plate 24. It can change the surface contact between the inner wall of the slot 12 and the limiting rib plate 24 into a line-surface contact between the second limiting rib 122 and the limiting rib plate 24, thereby reducing the friction during the assembly of the buckle assembly 21 and the slot 12, and facilitating the assembly of the water receiving tray 2 and the chassis 11.

[0100] Furthermore, see the attached document. Figure 8 and attached Figure 11 As shown, the lower end of the second limiting rib 122 has a fifth guide slope 123. In the top-to-bottom direction, the fifth guide slope 123 is inclined away from the axis of the slot 12, thus providing guidance when assembling the water tray 2 onto the chassis 11. This allows the fifth guide slope 123 to abut against the limiting rib plate 24 during assembly, facilitating the insertion of the snap-fit ​​assembly 21 and the assembly of the water tray 2 with the heat exchanger bracket 1. It should be noted that the limiting rib plate 24 moves relative to the fifth guide slope 123 from its lower end to its upper end, thereby gradually engaging the snap-fit ​​assembly 21 with the slot 12.

[0101] It should be noted that the setting of the first limiting rib 245 and the second limiting rib 122 can both increase the gap between the limiting rib plate 24 itself and the inner wall of the slot 12, so that some of the condensate on the chassis 11 can flow from the gap between the limiting rib plate 24 and the inner wall of the slot 12 to the water receiving tray 2. This increases the path of condensate from the chassis 11 to the water receiving tray 2, making it easier for condensate to flow into the water receiving tray 2 and for condensate to be discharged. It also prevents condensate in the chassis 11 from overflowing and dripping into other places inside the air conditioner 100, thus ensuring the user's experience.

[0102] In a further embodiment of this utility model, reference is made to the appendix. Figure 9 Appendix Figure 13 and attached Figure 14 As shown, the mounting base 22 includes a base 221 and a first boss 222. The base 221 is located on the upper side of the water receiving tray 2, and the first boss 222 is located on the upper side of the base 221 and abuts against the lower end face of the chassis 11. This can restrict the water receiving tray 2 from moving towards the chassis 11, ensuring the relative position of the chassis 11 and the water receiving tray 2. This prevents relative vertical movement between the water receiving tray 2 and the heat exchanger bracket 1 after the heat exchanger assembly 10 is assembled, thereby ensuring the reliability and stability of the connection between the water receiving tray 2 and the heat exchanger bracket 1, preventing the components inside the air conditioner 100 from shaking during transportation, and thus extending the service life of the heat exchanger assembly 10.

[0103] Further, see attached document. Figure 9 Appendix Figure 13 and attached Figure 14 As shown, along the width direction of the mounting base 22 (refer to the attached diagram) Figure 14 As shown in the j-direction, the width of the first protrusion 222 is smaller than the width of the base 221, resulting in a gap between the upper end face of the base 221 and the lower end face of the chassis 11. When some of the condensate on the chassis 11 flows into the gap between the limiting rib plate 24 and the inner wall of the slot 12, the condensate can flow down along the side wall of the first protrusion 222 and flow from the gap between the upper end face of the base 221 and the lower end face of the chassis 11 to the water receiving tray 2. This increases the path of condensate from the chassis 11 to the water receiving tray 2, making it easier for condensate to flow into the water receiving tray 2 and for condensate to be discharged. This prevents condensate in the chassis 11 from overflowing and dripping into other places inside the air conditioner 100, ensuring the user's experience.

[0104] In a further embodiment of this utility model, reference is made to the appendix. Figure 6 Appendix Figure 10 and attached Figure 13As shown, there are multiple spaced-apart snap-fit ​​components 21, and multiple slots 12 corresponding one-to-one with each snap-fit ​​component 21. Through the cooperation of the multiple snap-fit ​​components 21 and the multiple slots 12, the water tray 2 can be fixed to the base 11 at multiple spaced points on the water tray 2, improving the reliability and stability of the connection between the water tray 2 and the base 11. Simultaneously, in the event of a collision or drop of the air conditioner 100, the multiple mating points between the water tray 2 and the heat exchanger bracket 1 can distribute pressure, further preventing the water tray 2 from detaching from the heat exchanger bracket 1, greatly increasing the reliability of the water tray 2 installation. In a specific example, refer to the attached diagram. Figure 6 Appendix Figure 10 and attached Figure 13 As shown, there are three snap-fit ​​components 21 spaced apart in the circumferential direction of the water receiving tray 2. The three snap-fit ​​components 21 are located at the left end, right end and rear end of the water receiving tray 2, respectively. There are three slots 12 that correspond one-to-one with the three snap-fit ​​components 21. The water receiving tray 2 can be fixed to the chassis 11 from the left end, right end and rear end of the water receiving tray 2, thereby improving the reliability and stability of the connection between the water receiving tray 2 and the chassis 11.

[0105] In a further embodiment of this utility model, reference is made to the appendix. Figure 9 As shown, the water receiving tray 2 is connected to the base 11 by a fastener 15, which facilitates assembly and disassembly, reducing the assembly difficulty of the heat exchanger assembly 10 and ensuring the reliability of the connection between the water receiving tray 2 and the heat exchanger bracket 1. For example, the fastener 15 can be a screw. In a specific example, refer to the attached diagram. Figure 9 As shown, one of the multiple second protrusions 25 is provided with a mounting hole 251, and the lower surface of the chassis 11 is provided with a downwardly extending mounting post 14. The mounting hole 251 and the mounting post 14 are arranged opposite to each other. The fastener 15 can pass through the mounting hole 251 and be fixed in the mounting post 14, thereby realizing the connection and fixation between the water receiving tray 2 and the chassis 11.

[0106] It is understandable that when assembling the water receiving tray 2 onto the heat exchanger bracket 1, the water receiving tray 2 is first snapped into the base 11, and then the water receiving tray 2 is connected to the base 11 using fasteners 15. This can relatively reduce the difficulty of connecting the fasteners 15 and reduce the assembly difficulty of the water receiving tray 2 and the heat exchanger bracket 1. Compared with the prior art that uses three screws to fix the water receiving tray to the base, this utility model, due to the snap-fit ​​between the water receiving tray 2 and the base 11, can reduce the number of fasteners 15 used while ensuring the reliability of the connection between the water receiving tray 2 and the base 11, thereby reducing the cost of the heat exchanger assembly 10, reducing the assembly difficulty of the water receiving tray 2, and improving the assembly efficiency of the heat exchanger assembly 10.

[0107] In some embodiments of this utility model, reference is made to the appendix. Figure 9As shown, a second protrusion 25 is provided on the upper side of the drip tray 2. The second protrusion 25 and the drain hole 13 are arranged opposite each other in the vertical direction. The condensate on the base 11 can drip from the drain hole 13 onto the second protrusion 25, and then flow into the drip tray 2 along the side wall of the second protrusion 25. This can relatively reduce the distance between the upper surface of the base 11 and the drip tray 2, improve the situation where the condensate drips directly onto the bottom wall of the drip tray 2 and causes excessive noise. It can also improve the situation where the condensate drips into the drip tray 2 and splashes to a certain extent, reduce the probability of condensate splashing onto other parts inside the air conditioner 100, and improve the user experience.

[0108] In a further embodiment of this utility model, reference is made to the appendix. Figure 9 As shown, on a plane perpendicular to the vertical direction, the projection of the drain hole 13 is entirely within the projection of the second protrusion 25, which ensures that the condensate dripping from the drain hole 13 will drip onto the second protrusion 25, thereby ensuring the effectiveness of the second protrusion 25 in improving the excessive noise of condensate dripping and ensuring the effectiveness of the second protrusion 25 in preventing condensate splashing.

[0109] In a further embodiment of this utility model, reference is made to the appendix. Figure 9 As shown, the lower surface of the chassis 11 is provided with an extension column 131, through which the drain hole 13 passes. The extension column 131 and the second protrusion 25 are spaced apart in the vertical direction. The extension column 131 and the second protrusion 25 are arranged opposite to each other. The extension column 131 can guide the condensate dripping from the drain hole 13, further preventing the condensate from splashing during the dripping process, reducing the probability of condensate splashing onto other components inside the air conditioner 100, and improving the user experience.

[0110] In a further embodiment of this utility model, reference is made to the appendix. Figure 9 As shown, the distance h between the lower end face of the extension column 131 and the upper end face of the second protrusion 25 satisfies 3.5mm ≤ h ≤ 8mm. This avoids the distance between the lower end face of the extension column 131 and the upper end face of the second protrusion 25 being too small, ensuring that condensate flows from the gap between the lower end face of the extension column 131 and the upper end face of the second protrusion 25 into the drip tray 2. It also avoids the distance between the lower end face of the extension column 131 and the upper end face of the second protrusion 25 being too large, relatively reducing the noise generated by condensate dripping onto the second protrusion 25. Furthermore, it can improve the situation of condensate splashing, reducing the probability of condensate splashing onto other components inside the air conditioner 100, and improving the user experience. For example, the distance h between the lower end face of the extension column 131 and the upper end face of the second protrusion 25 can be 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, or 8mm.

[0111] In a further embodiment of this utility model, reference is made to the appendix. Figure 10 and attached Figure 13 As shown, there are multiple drain holes 13, and multiple second protrusions 25 corresponding one-to-one with the multiple drain holes 13. This allows condensate in the chassis 11 to flow from the multiple drain holes 13 to the second protrusions 25, and finally to the drip tray 2. This increases the path for condensate to flow from the chassis 11 to the drip tray 2, making it easier for condensate to flow into the drip tray 2 and for condensate to be discharged. It also prevents condensate in the chassis 11 from overflowing and dripping onto other parts of the air conditioner 100, thus ensuring the user's experience.

[0112] This utility model also proposes an air conditioner 100 having the heat exchanger assembly 10 of the above embodiments.

[0113] like Figure 1 , Figure 2 and Figure 3 As shown, the air conditioner 100 according to an embodiment of the present utility model includes a housing 20, an air duct assembly 30, and the heat exchanger assembly 10 described above.

[0114] Specifically, see the attached document. Figure 1 As shown, the housing 20 can protect the internal structure of the air conditioner 100, preventing the internal structure of the air conditioner 100 from being exposed and damaged, which helps to extend the service life of the air conditioner 100, and also has a better appearance.

[0115] Further, see Appendix Figure 1 and attached Figure 2 As shown, the housing 20 includes a panel assembly 201, a top cover component 202, a chassis component 203, a rear housing component 204, and an air outlet frame 205. The panel assembly 201 includes an upper panel 2011 and a lower panel 2012, which are positioned vertically (e.g., in the vertical direction). Figure 1 The arrangement and connection of the upper panel 2011 and lower panel 2012 (as shown) helps to reduce the production and maintenance costs of the air conditioner 100. The upper panel 2011 and lower panel 2012 are both located on the front side of the air outlet frame 205. Part of the air outlet frame 205 is connected to the upper panel 2011 and part is connected to the lower panel 2012. The rear housing component 204 is located on the rear side of the air outlet frame 205. The lower ends of the rear housing component 204 and the air outlet frame 205 are both connected to the chassis component 203. The top cover component 202 is connected to the end of the rear housing component 204 and the air outlet frame 205 that is away from the chassis component 203, thus forming an integral structure to protect the internal structure of the air conditioner 100 and prevent users from contacting the interior and causing injury.

[0116] Furthermore, see the attached document. Figure 1 and attached Figure 2As shown, the housing 20 is provided with an air inlet 206 and an air outlet 208. The air inlet 206 is located on the rear housing component 204 and extends along the length of the rear housing component 204 (see attached diagram). Figure 2 Extending in the vertical direction shown, the air outlet 208 is located on the air outlet frame 205 and along the length of the air conditioner 100 (see attached diagram). Figure 1 Extending in the vertical direction (as shown), the airflow outside the air conditioner 100 can enter the air conditioner 100 through the air inlet 206, and then blow it into the room through the air outlet 208, thereby regulating the indoor temperature.

[0117] Further, see attached document. Figure 1 and attached Figure 3 As shown, both the heat exchanger assembly 10 and the air duct assembly 30 are located inside the housing 20. The air duct assembly 30 can drive the airflow outside the air conditioner 100 into the housing 20. Along the airflow direction, the air duct assembly 30 is located downstream of the heat exchanger assembly 10, which facilitates the air duct assembly 30 driving the airflow outside the air conditioner 100 to enter the housing 20 from the air inlet 206. This allows the airflow inside the air conditioner 100 to exchange heat with the heat exchanger assembly 10 first, and then, driven by the air duct assembly 30, blown out of the air conditioner 100 through the air outlet 208, thereby achieving the effect of regulating the indoor temperature and meeting the user's needs.

[0118] Furthermore, see the attached document. Figure 1 and attached Figure 2 As shown, an air inlet grille 207 is provided at the air inlet 206. On the one hand, the air inlet grille 207 can prevent hands or other foreign objects from entering the air conditioner 100, protecting the safety of the user and ensuring the normal operation of the air conditioner 100. On the other hand, the air inlet grille 207 can prevent insects, rodents, etc. from entering the casing 20 of the air conditioner 100 and causing damage to the air conditioner 100, ensuring the normal operation of the air conditioner 100 and ensuring the aesthetic appearance of the air conditioner 100.

[0119] Optionally, refer to the appendix. Figure 1 and attached Figure 2 As shown, the air inlet grille 207 can be arranged opposite to the heat exchanger assembly 10 and the air duct assembly 30, so that the air duct assembly 30 can drive the airflow outside the air conditioner 100 to enter the air conditioner 100 through the air inlet grille 207, making the airflow smoother, increasing the air intake volume, improving the air intake efficiency of the air duct assembly 30, reducing the noise of the air conditioner 100 during operation, and improving the performance and comfort of the air conditioner 100.

[0120] Optionally, the air intake grille 207 is detachably connected to the housing 20. The air intake grille 207 can ensure the aesthetic appearance of the housing 20, and after the air intake grille 207 is removed, it is convenient to repair and replace the components inside the air conditioner 100. At the same time, it is convenient to clean the air intake grille 207, avoiding dust accumulation caused by prolonged use.

[0121] Optionally, the housing 20 may contain at least one of a purification component and a humidification component. Different components can be selected according to different actual needs to meet different usage requirements. The purification component purifies the airflow entering the air conditioner 100, allowing the purified airflow to be blown into the room, thus improving air quality. The humidification component humidifies the airflow entering the air conditioner 100, allowing the humidified airflow to be blown into the room, increasing the indoor moisture content and achieving a humidification effect.

[0122] According to an embodiment of the present invention, the air conditioner 100 includes the aforementioned heat exchanger assembly 10. A drain hole 273 and multiple baffles 274 are provided on the bottom wall of the water receiving tray 27. These baffles 274 are spaced apart in the circumferential direction of the drain hole 273. The arrangement of the baffles 274 allows condensate to flow between adjacent baffles 274 and blocks large solid objects, wool, or other debris, preventing these objects from flowing with the condensate to the drain hole 273. This reduces the probability of the drain hole 273 and drain pipe 275 being blocked by debris, ensuring normal drainage of the water receiving tray 2, reducing the probability of air conditioner 100 malfunctions, improving the reliability of air conditioner 100, and enhancing the user experience. Furthermore, the cross-sectional area of ​​the baffles 274 gradually decreases from bottom to top, facilitating demolding of the baffles 274 and simplifying the production of the water receiving tray 2, thus reducing the difficulty of its production.

[0123] Other components and operations of the water receiving tray 2, heat exchanger assembly 10, and air conditioner 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
