[0029] The following detailed description of the present application will be given of examples of the present application, examples of which are shown in the drawings. The following description of the present application will be given for illustrative purposes only and should not be construed as limiting the present application.

[0030] An embodiment of the present application provides a drain pan for use in an air conditioner, which can improve the suction and discharge efficiency, have high overall structural stability, and improve the convenience and accuracy of installation in the air conditioner. The air conditioner may be a central air conditioner, and the drain pan can be installed in the suction and discharge device in the central air conditioner room.

[0031] 1 to 6, the drain pan of the embodiment of the present application mainly includes two parts, a plastic member 10 and a foam member 20, which are connected together as a single unit, eliminating the need to use connecting members such as screws. Although the plastic member 10 and the foam member 20 are made of different materials, they have an integrated structure and do not need to be assembled separately when in use, which improves installation convenience, improves production efficiency, and is also advantageous for the accuracy of the relative positioning of the air intake 11 and related components of the air conditioner.

[0032] 1 and 3, an inlet 11 is formed in the center of the plastic member 10, and an outlet 12 is formed near the edge of the plastic member 10. A water groove 17 is formed between the inlet 11 and the outlet 12. The water groove 17 surrounds the inlet 11, and the outlet 12 continuously surrounds at least a portion of the outer edge of the water groove 17. A plurality of support grilles 14 are provided within the outlet 12, and the plurality of support grilles 14 are distributed at intervals along the extension direction of the outlet 12. In the embodiment of the present application, only one outlet 12 is provided, and the water groove 17 is continuously surrounded to form an annular outlet, thereby increasing the circulation area of ​​the outlet 12. Although the support grille 14 is provided within the outlet 12, the circulation area of ​​the outlet 12 occupied by the support grille 14 is very small, and the total circulation area of ​​the outlet 12 far exceeds the combined circulation area of ​​multiple outlets in the related art. The water groove 17 is elongated and extends in a predetermined direction to receive condensed water and transport the collected condensed water to a predetermined duct. In some embodiments, the water groove 17 is a continuous groove, allowing the condensed water to flow through the water groove 17. The support grill 14 is a plate-like body, and the thickness of the support grill 14 gradually decreases along the air outlet direction, meaning that the cross-sectional width at different positions on the support grill 14 may vary. This arrangement not only reduces wind resistance but also has the effect of reducing noise.

[0033] In related technology, the drain pan is formed by foaming a foam material, and because foam has low strength, it is necessary to install a long connecting structure at the air outlet to connect the frame, which results in a large obstruction of the air outlet.

[0034] In some embodiments, the foam member 20 and the plastic member 10 are integrally molded.

[0035] In this application, the drain pan is formed by foaming a foam in a plastic member, which has high strength. Using a drain pan formed by such a process provides high strength and allows the cross section of the support grill 14 for connecting the first frame 16 at the air outlet to be very small. As shown in Figure 3, the proportion between the shielding area occupied by the support grill 14 at the air outlet and the total area of ​​the air outlet is so small that it can be ignored, making it possible to realize an annular air outlet.

[0036] For example, the air outlet 12 is an elongated hole with a certain length and curvature, and the width of the air outlet 12 can be set according to actual design requirements.

[0037] The support grille 14 plays a role in supporting the connection, and can be made as thin as possible while still satisfying the structural strength requirements, thereby reducing wind resistance.

[0038] Referring to FIG. 2 , the foam member 20 at least partially overlaps the plastic member 10, maintaining temperature and preventing condensation in the drain pan. The foam member 20 avoids the inlet 11 and the outlet 12. The foam member 20 and the plastic member 10 are connected to each other and fixed relative to each other. In some embodiments, the foam member 20 and the plastic member 10 are integrally molded, and a water-receiving groove 17 is formed in the foam member 20, surrounding the inlet 11 and the outlet 12. Because the foam member 20 and the plastic member 10 are integrally molded, the foam member 20 and the plastic member 10 do not need to be attached separately. Although the foam member 20 and the plastic member 10 are made of different materials, they can both be formed by injection molding. Therefore, by controlling the injection sequence of the different materials, the foam member 20 and the plastic member 10 can be molded separately and then connected together.

[0039] In some embodiments, in order to avoid the suction port 11 and the outlet 12, an intake relief hole 23 is opened in the center of the foam member 20, and an outlet relief hole 24 is opened between the second frame 25 and the water receiving groove 17. The position of the intake relief hole 23 corresponds to the suction port 11, and the position of the outlet relief hole 24 corresponds to the outlet 12. The intake relief hole 23 is circular to fit the suction port 11, and the outlet relief hole 24 is a curved elongated hole to fit the shape of the outlet 12.

[0040] In some embodiments, the support grill 14 is disposed along the direction from the air inlet 11 to the air outlet 12. The width of the support grill 14 ranges from 1.5 mm to 3.2 mm. Because the entire plastic member 10 is made of plastic, the mold opening width of the support grill 14 can be controlled to 1.5 mm or more. Experiments have shown that, depending on the structural strength of the drain pan, the width of the support grill 14 in this embodiment is limited to 3.2 mm or less. Therefore, the width of the support grill 14 may be 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3.0 mm, etc. A support grill 14 of this size not only has sufficient structural strength, but also provides very little wind resistance to the air outlet 12, achieving a larger airflow area and improving airflow efficiency.

[0041] Here, the width of the support grill 14 refers to the thickness of the support grill 14 occupying the cross section of the air outlet 12, that is, the distance between the two sides of the support grill 14 in Fig. 3. The support grill 14 is a plate-like body, and the width of the support grill 14 here is the maximum thickness of the plate-like body.

[0042] The plastic member 10 mainly plays a role in supporting the structure of the entire drain pan, and the foam member 20 mainly plays a role in maintaining heat for the entire drain pan. When a support grill is provided on the foam member 20, it is difficult to control the width of the support grill to 1.5 mm to 3.2 mm due to the properties of the material itself. In the related art solution of providing a support grill on the foam member 20, the width of the support grill is usually around 10 mm, which results in high wind resistance to the air outlet 12.

[0043] In some embodiments, the foam member 20 and the plastic member 10 are integrally molded, which eliminates assembly errors and eliminates gaps between the air guide ring and the air conditioner fan wheel. The term "integral molding" refers to the injection of the two members into a single unit during injection molding, which simplifies the assembly process and provides good fit between the foam member 20 and the plastic member 10, minimizing individual variations in the drain pan.

[0044] In some embodiments, the process for integrally molding the foam member 20 and the plastic member 10 is as follows: First, the plastic member 10 is injection-molded, and after the molded plastic member 10 is cured, a foam material is directly injected into the plastic member 10 using a mold, so that the foam material and the plastic member 10 are at least partially melted and integrated, and after the foam material is cured, it is connected to the plastic member 10.

[0045] The structural strength of the plastic member 10 is higher than that of the foam member 20. Therefore, the plastic member 10 is first injection-molded, and after the plastic member 10 has hardened, a foam material is injection-molded, thereby forming the foam member 20 on the plastic member 10. The plastic member 10 and the foam member 20 are at least partially melted and integrated, forming an integrally molded structure in which the plastic member 10 and the foam member 20 are two inseparable parts. This eliminates the need to assemble them separately when producing the air conditioner, and the relative positional precision of the plastic member 10 and the foam member 20 is very high, eliminating assembly errors.

[0046] When the foaming material is injected, the surface of the plastic member 10 in contact with the foaming material may be partially melted and integrated with the foaming material. The contacting portion between the plastic member 10 and the foaming member 20 does not need to be melted with each other.

[0047] In some embodiments, the width of the support grill 14 is in the range of 2 mm to 3 mm, for example, 2 mm to 2.5 mm. A support grill 14 of this size not only has sufficient structural strength, but also has very little wind resistance to the air outlet 12, realizing a larger air outlet area and improving air outlet efficiency.

[0048] The plastic member 10 has a first frame 16, one end of the support grill 14 is connected to the first frame 16, and the other end is connected to the central structure of the plastic member 10. The first frame 16 is integrally connected to a second frame 25, with the first frame 16 providing support and the second frame 25 providing heat retention.

[0049] In some embodiments, the cross section of the support grille 14 gradually decreases along the airflow direction, i.e., the width of the cross section of the support grille 14 may vary at different positions. This arrangement can further reduce wind resistance and have a noise reduction effect. The arrows in Figures 1 and 5 indicate the airflow and intake directions.

[0050] The support grill 14 is a plate-like body, and the maximum width of the cross section of the support grill 14 is in the range of 1.5 mm to 3.2 mm.

[0051] In some embodiments, the shape of the air inlet 11 is circular, and the shape of the water groove 17 is rectangular. The four corners of the water groove 17 are chamfered in an arc shape, and the size of the air inlet 11 matches the size of the fan wheel of the air conditioner. In some embodiments, referring to FIG. 5, the shape of the air inlet 11 is circular, and the inner diameter of the air inlet 11 gradually decreases along the suction direction (from bottom to top). This structure is advantageous for improving the suction effect and reducing suction noise. The directions of the arrows in the drawings indicate the suction and blowout directions.

[0052] In some embodiments, the outlet 12 surrounds the four outer edges of the water receiving groove 17, and each outer edge is connected to one support grill 14. This arrangement ensures the stability of the entire drain pan structure.

[0053] For example, the air outlet 12 has three bending positions, and each bending position is provided with two support grills 14. The plane on which the support grills 14 are located overlaps with the center of the air inlet 11.

[0054] In some embodiments, the plastic member 10 has a plurality of connectors 13 that penetrate the foam member 20. The connectors 13 may be used to connect the drain pan to other components of the air conditioner. By installing the connectors 13 so that they penetrate the foam member 20, the stability of the integrally molded structure of the plastic member 10 and the foam member 20 can be improved.

[0055] For example, the connection portion 13 may have a columnar structure, and a screw hole may be provided in the center of the connection portion 13, and other components of the air conditioner element can be attached to the drain pan through the screw hole.

[0056] In some embodiments, an air guide ring 15 is formed in the center of the plastic member 10, and the air inlet 11 is formed in the center of the air guide ring 15, and the air guide ring 15 does not overlap with the foam member 20. Because the plastic member 10 has an integral structure and the air guide ring 15 is part of the plastic member 10, the drain pan of the embodiment of the present application does not need to have a separate air guide ring member attached when in use, that is, the drain pan of the embodiment of the present application simultaneously has the structure of an air guide ring, and this installation improves the fitting precision between the air guide ring 15 and the fan wheel of the air conditioner, and eliminates the need to attach a separate air guide ring member, thereby improving the production efficiency of the air conditioner.

[0057] For example, the inner surface of the air guide ring 15 is an arcuate surface or a tapered surface. This structure is advantageous for improving the suction effect of the suction port 11 and further reducing suction noise.

[0058] For example, referring to FIG. 5, the cross-sectional shape of the air guide ring 15 may be a quarter-circular structure.

[0059] 7, in some embodiments, the air inlet 11 is covered with a protective net 30, which is removably connected to the foam member 20 or the plastic member 10. The protective net 30 provides a protective effect and may be made of stainless steel. Specifically, the protective net 30 and the plastic member 10 can be connected by screws or snaps.

[0060] In some embodiments, the safety net 30 may be a grill 30 .

[0061] In some embodiments, the foam member 20 is provided with a negative ion element mounting portion for mounting the negative ion element 1 and a temperature sensor mounting portion for mounting the temperature sensor 2, and the ion element mounting portion is located on one side of the temperature sensor mounting portion.

[0062] A float may be provided in the foam member 20, and the drain pan simultaneously serves to fix and assemble the float, negative ion element 1, and temperature sensor 2, and also has a corresponding structure for fixing the wiring and other wiring, so that there are no additional unrelated structures, and the overall volume is small and the material utilization rate is high, provided that the structural strength is ensured.Here, the negative ion element 1 and temperature sensor 2 are provided at the suction port 11, which is advantageous for temperature detection by the temperature sensor 2 and air purification by the negative ion element 1.

[0063] Here, the foam member 20 has a wiring passage groove 22 through which the connection wires of electronic elements such as the negative ion element 1 and the temperature sensor 2 can pass.

[0064] In some embodiments, the number of wire passing grooves 22 is two, and the two wire passing grooves 22 are located near the two extended ends of the air outlet 12, respectively, so that the air outlet 12 has an unclosed annular structure.

[0065] An embodiment of the present application further provides an air conditioner, which includes the drain pan of any one of the above embodiments, and the drain pan of the air conditioner is easy to install, which improves the production efficiency of the air conditioner, the width of the support grille 14 is small, the air outlet effect is good, and the user experience is improved.

[0066] 8, a grill 30 according to an embodiment of the present application includes a body 31 suitable for being connected to a drain pan. The body 31 of the grill 30 can serve the roles of filtering and ventilation.

[0067] In some embodiments, the body 31 can be secured to a drain pan via a number of screws.

[0068] In some embodiments, as shown in FIGS. 8 and 10 , the main body 31 is provided with a plurality of first buckles 311, which are suitable for buckling into drain pan buckles to connect the main body 31 and the drain pan 40. The buckle connection between the grille 30 and the drain pan 40 facilitates detachment of the grille 30 and the drain pan 40, thereby facilitating inspection and maintenance. This avoids the need to manually lift panels to install or secure them, as in the related art, thereby reducing labor burden and labor costs, facilitating panel alignment, and improving installation efficiency. Furthermore, the related art embeds sheet metal members in the drain pan in advance, thereby avoiding the situation in which there are many members below the drain pan, which reduces drain pan production efficiency.

[0069] As shown in FIG. 8, the body 31 may be circular, but the body 31 may also be other shapes such as a square, a star, an oval, etc.

[0070] In some embodiments, the first buckle 311 may be a locking buckle. A plurality of the first buckles 311 may be arranged at intervals along the circumferential direction of the main body 31, and when the grille 30 is installed, the plurality of first buckles 311 can be locked and fixed to the drain pan.

[0071] In some embodiments, the multiple first buckles 311 are spaced apart along the circumferential direction of the main body 1, and the multiple first buckles 311 engage with or disengage from the drain pan when the main body 31 rotates relative to the drain pan.

[0072] 8, the first buckle 311 may also be a rotating buckle, with the multiple first buckles 311 all located at the edge of the main body 31 and spaced at equal intervals around the periphery of the main body 31. When installing the grille 30, the grille 30 is rotated, and the multiple first buckles 311 on the main body 31 can lock and engage with the drain pan 40 during the rotation, thereby realizing the installation and fixing of the grille 30 and the drain pan 40. When it is necessary to remove the grille 30, the grille 30 can be rotated in the opposite direction, making it even easier to install and remove the grille 30.

[0073] In some embodiments, the main body 31 is provided with a first hole 312 for inserting a first fastening member, and the main body 31 is removably connected to the drain pan 40 via the first fastening member.

[0074] Referring to FIG. 8, the first hole 312 may be provided at the edge of the main body 31, and the first fastening member may be a bolt or a screw. After the grille 30 is rotationally locked or buckled to the drain pan 40, the grille 30 can be connected and fixed to the drain pan 40 through the first fastening member, thereby limiting the rotation of the grille 30 and preventing the grille 30 from loosening or falling off due to rotation.

[0075] Only one first fastening member may be provided, and the grille 30 can be removed by removing the first fastening member and then unlocking each of the first buckles 311, thereby avoiding the situation in the related art where multiple screws need to be removed, improving the efficiency of installing and removing the grille 30, and facilitating inspection and maintenance.

[0076] In some embodiments, the main body 31 is provided with a reinforcing rib 314, which is provided between two adjacent first buckles 311 and extends along the circumferential direction of the main body 31. As shown in Fig. 8, the reinforcing rib 314 may be provided at the outer peripheral edge of the main body 31, and the reinforcing rib 314 may extend in a curved manner along the circumferential direction of the main body 31, with one end of the reinforcing rib 314 connected to one of the two adjacent first buckles 311 and the other end of the reinforcing rib 314 connected to the other of the two adjacent first buckles 311, thereby improving the structural strength of the main body 31 and ensuring the structural stability of the shape of the main body 31.

[0077] In some embodiments, the reinforcing ribs 314 and the body 31 are integrally injection molded.

[0078] In some embodiments, the material of the body 31 is plastic, which facilitates injection molding of the grille 30, and because the body 31 is provided with reinforcing ribs, the grille 30 still has high structural strength and avoids the situation where the body 31 is prone to deformation when using plastic.

[0079] In some embodiments, there are a plurality of reinforcing ribs 314 , and the plurality of reinforcing ribs 314 and the plurality of first buckles 311 are alternately arranged along the circumferential direction of the main body 31 .

[0080] 8, a plurality of reinforcing ribs 314 are provided on the outer periphery of the main body 31, and the number of reinforcing ribs 314 may be the same as the number of first buckles 311, or the reinforcing ribs 314 and the first buckles 311 may be arranged alternately one by one along the circumferential direction of the main body 31, that is, one reinforcing rib 314 is provided between any two adjacent first buckles 311, and they are connected by this reinforcing rib 314. This increases the structural strength of the outer periphery of the main body 31 and ensures the stability of the shape of the main body 31.

[0081] In some embodiments, a reinforcing rib 314 may be provided between some two adjacent first buckles 311 .

[0082] In some embodiments, the first holes 312 are provided in the reinforcing ribs 314. Specifically, the first holes 312 may be provided in the reinforcing ribs 314 and penetrate the main body 31 along the thickness direction of the main body 31. This avoids a situation where the placement of the first holes 312 weakens the local structural strength of the main body 31.

[0083] In some embodiments, the grill 30 further includes a mounting portion 32, which is provided on the outer periphery of the main body 31 and is suitable for mounting the temperature sensor 2 and / or the negative ion element 1. The mounting portion 32 can serve to fix the temperature sensor 2 and the negative ion element 1.

[0084] As shown in Fig. 8, the mounting portion 32 may be installed integrally with the main body 31. In some embodiments, the mounting portion 32 may be removably fixed to the main body 31. For example, the mounting portion 32 may be fixed to the main body 31 via a screw. The mounting portion 32 is fixed to the outer periphery of the main body 31, and may be used to fix the temperature sensor 2 or the negative ion element 1. Note that the temperature sensor 2 and the negative ion element 1 may be fixed to the mounting portion 32 at the same time.

[0085] On the one hand, installing the mounting portion 32 serves to fix the temperature sensor 2 and the negative ion element 1, making it easier to install the temperature sensor 2 and the negative ion element 1; on the other hand, the temperature sensor 2 and the negative ion element 1 at the mounting portion 32 do not block the position of the main body 31, preventing the temperature sensor 2 and the negative ion element 1 from affecting the outlet return air area, which is advantageous for improving the cooling efficiency of the air conditioner.

[0086] In some embodiments, a second buckle 321 is provided on the mounting portion 32, and the temperature sensor 2 is fastened to the mounting portion 32 via the second buckle 321. Specifically, as shown in Fig. 8, the second buckle 321 is a fastening buckle, and the second buckle 321 may be provided integrally with the mounting portion 32. When attaching the temperature sensor 2, the second buckle 321 can be fastened directly to the temperature sensor 2, making it easy to attach and detach the temperature sensor 2.

[0087] In some embodiments, the second buckle 321 includes a first sub-buckle 3211 and a second sub-buckle 3212, which are spaced apart, and the temperature sensor 2 is fastened between the first sub-buckle 3211 and the second sub-buckle 3212.

[0094] 9, the protrusion 322 may be composed of a first segment 3221 and a second segment 3222, the first segment 3221 being arc-shaped and the second segment 3222 being linear, the second segment 3222 being provided on the concave side of the first segment 3221, the second segment 3222 extending roughly along the diameter of the circle corresponding to the first segment 3221, and one end of the second segment 3222 being connected to the center of the first segment 3221. The convex surface is used for bonding contact with the outer peripheral wall of the negative ion element 1.

[0095] The arc surface 3223 is provided on the convex surface of the first segment 3221. This simplifies the structure of the protrusion 322, which is advantageous in reducing consumable materials used for the protrusion 322 and reducing costs, and also ensures that the protrusion 322 has high structural strength, thereby meeting the requirements of lamination position regulations.

[0096] In some embodiments, the mounting portion 32 is provided with a second hole 323, and the negative ion element 1 is removably mounted to the mounting portion 32 via a second fastening member, the second hole 323 being suitable for insertion of the second fastening member. As shown in FIG. 8, the mounting portion 32 may be provided with two second holes 323, each of which may be located close to a corresponding protrusion 322.
