[0002] In related technologies, when an air conditioner is in cooling mode, the cold air, after exchanging heat with the heat exchanger, flows sequentially through the air duct assembly and the air outlet frame assembly. This results in a low surface temperature for the air duct assembly and the air outlet frame assembly, making it easy for moisture in the air to condense on these components, forming condensate. This condensate flows downwards or drips due to gravity, potentially causing short circuits or other hazards if it drips onto other parts of the air conditioner, or it may drip onto the ground, causing inconvenience to the user. Therefore, improvements are needed. Summary of the Invention

[0072] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0073] The following is for reference. Figures 1-30 An air conditioner according to an embodiment of the present invention is described.

[0074] An air conditioner according to an embodiment of the present invention, referring to Figures 1-4 It includes: housing assembly 60, heat exchange and air supply assembly 65, and water receiving tray.

[0075] The housing assembly 60 includes a front housing component 601 and a rear housing component 63 connected front and rear. The front housing component 601 forms an air outlet 12, and the rear housing component 63 forms an air inlet 64. The front housing component 601 includes an air outlet frame assembly 101, which forms an air outlet channel 11. The air outlet end of the air outlet channel 11 constitutes the air outlet 12. The bottom wall of the air outlet channel 11 is an air outlet bottom wall 32, and the air outlet bottom wall 32 forms a bottom water collection groove 35. By forming a bottom water collection groove 35 on the air outlet bottom wall 32, condensate from the air outlet frame assembly 101 can flow down along the air outlet frame assembly 101 to the bottom water collection groove 35 for collection. This prevents condensate from dripping onto other components inside the air conditioner and causing a short circuit hazard, and also prevents condensate from dripping onto the ground and causing inconvenience to the user.

[0076] For example, two air outlets 12 can be formed on the housing assembly 60, the two air outlets 12 are arranged at intervals in the left and right direction, and each air outlet 12 is provided with a corresponding air guide plate 51.

[0077] For example, the housing assembly 60 may include a rear housing component 63 and a front housing component 601. The rear housing component 63 is connected to the rear side of the front housing component 601 and has an air inlet 64. The front housing component 601 may include a front housing 62 and an air outlet frame assembly 101. The air outlet frame assembly 101 is mounted on the front housing 62. The air duct assembly 69 may be located between the heat exchanger assembly 651 and the air outlet frame assembly 101. The air outlet frame assembly 101 has an air outlet channel 11 and an air outlet 12, and the air guide plate 51 is rotatably connected to the air outlet frame assembly 101.

[0078] Furthermore, the air outlet frame assembly 101 may include an air outlet frame 10 and a front panel 61. Two air outlets 12 are formed on the air outlet frame 10. The two air outlets 12 are arranged at intervals in the left and right direction. Each air outlet 12 is provided with a corresponding air guide plate 51. The front panel 61 is connected to the front side of the air outlet frame 10 and is located between the two air outlets 12.

[0079] The housing assembly 60 also includes a base 73 and a top cover 16, with the front housing component 601 and the rear housing component 63 connected above the base 73, and the top cover 16 covering the top of the front housing component 601 and the rear housing component 63.

[0080] The heat exchange and air supply assembly 65 is disposed within the housing assembly 60 and includes a heat exchanger assembly 651 and an air duct assembly 69. The air duct assembly 69 is located between the heat exchanger assembly 651 and the air outlet frame assembly 101, and includes an air duct volute 71 and a fan wheel 701. An air duct is formed within the air duct volute 71, and at least a portion of the fan wheel 701 is located within the air duct. The bottom wall of the air duct is a bottom wall, and a water collection groove 72 is formed on the bottom wall of the air duct. By forming a water collection groove 72 on the bottom wall of the air duct, condensate from the air duct assembly 69 can flow downwards along the air duct assembly 69 and be collected in the water collection groove 72. This prevents condensate from dripping onto other components inside the air conditioner and causing a short circuit hazard, and also prevents condensate from dripping onto the ground and causing inconvenience to the user.

[0081] The bottom wall of the duct is lower than the bottom wall of the outlet 32, and the water in the bottom water collection tank 35 is suitable for flowing downward into the duct water collection tank 72. By making the bottom wall of the duct lower than the bottom wall of the outlet 32, a height difference can be created between the bottom wall of the duct and the bottom wall of the outlet 32. This allows the condensate in the bottom water collection tank 35 on the bottom wall of the outlet 32 ​​to flow downward into the duct water collection tank 72 on the bottom wall of the duct under its own gravity. In other words, the water in the bottom water collection tank 35 can flow downward into the duct water collection tank 72, so that the condensate in the bottom water collection tank 35 can be discharged in time, avoiding excessive condensate in the bottom water collection tank 35 and overflow.

[0082] For example, the air duct assembly 69 may include an air duct housing 71 and a fan 70, the fan 70 being mounted on the air duct housing 71 and used to drive airflow. The fan 70 includes a rotor 701 and a motor 702, the motor 702 being connected to the rotor 701 to drive the rotor 701 to rotate, thereby driving gas flow.

[0083] For example, heat exchanger assembly 651 may include heat exchanger component 66 and electric auxiliary heater 68. Heat exchanger component 66 includes heat exchanger 661 and heat exchanger bracket 67. Heat exchanger 661 is mounted on heat exchanger bracket 67, and electric auxiliary heater 68 is mounted on heat exchanger bracket 67.

[0084] The water collection tray is located below the heat exchange air supply assembly 65, for example, below the heat exchanger assembly 651. Condensate generated on the heat exchanger assembly 651 can flow downwards along the heat exchanger assembly 651 into the water collection tray for collection. Water in the duct water collection tank 72 is designed to flow downwards into the water collection tray. For example, a drainage structure can be provided on the bottom wall of the duct water collection tank 72 to drain the condensate downwards into the water collection tray. By positioning the water collection tray below the heat exchange air supply assembly 65 and allowing the water in the duct water collection tank 72 to flow downwards under its own gravity, the water stored in the duct water collection tank 72 can be drained in a timely manner, preventing excessive water accumulation and potential overflow, which could cause a hazard.

[0085] According to an embodiment of the present invention, by forming a bottom water collection groove 35 on the bottom wall 32 of the air outlet, condensate from the air outlet frame assembly 101 can flow down along the air outlet frame assembly 101 to the bottom water collection groove 35 for collection. By forming a duct water collection groove 72 on the bottom wall of the air duct, condensate from the air duct assembly 69 can flow down along the air duct assembly 69 to the duct water collection groove 72 for collection. This can prevent this condensate from dripping onto other components inside the air conditioner and causing danger, or dripping onto the ground and causing inconvenience to the user. By making the bottom wall of the air duct lower than the bottom wall 32 of the air outlet, and by including a water collection tray in the air conditioner, the water collected in the bottom water collection groove 35 can flow down into the duct water collection groove 72 under its own gravity, and finally flow into the water collection tray, preventing excessive water in the bottom water collection groove 35 and the duct water collection groove 72 from overflowing.

[0086] According to some embodiments of the present invention, with reference to Figure 15 A first overflow nozzle 36 is provided on the rear side of the air outlet bottom wall 32, and the drain end of the first overflow nozzle 36 is located directly above the duct water receiving tray 72. By providing the first overflow nozzle 36 on the rear side of the air outlet bottom wall 32, the condensate on the air outlet bottom wall 32 can leave the air outlet bottom wall 32 through the first overflow nozzle 36, which guides the flow of condensate. By placing the drain end of the first overflow nozzle 36 directly above the duct water receiving tray 72, the condensate flowing out of the first overflow nozzle 36 can drip into the duct water receiving tray 72 under its own gravity, preventing condensate from dripping onto other parts of the air conditioner and causing danger.

[0087] According to some embodiments of the present invention, with reference to Figures 12-14The air outlet frame assembly 101 includes an air outlet frame 10 and a front panel 61. The air outlet frame 10 forms an air outlet channel 11. The front panel 61 is connected to the front side of the air outlet frame 10. The air outlet frame 10 includes a front air outlet frame 13 and a rear air outlet frame 14 connected front to back. The air outlet bottom wall 32 includes a front air outlet bottom wall 321 and a rear air outlet bottom wall 322. The front air outlet bottom wall 321 is formed in the front air outlet frame 13, and the rear air outlet bottom wall 322 is formed in the rear air outlet frame 14. The bottom water receiving trough 35 includes a front bottom water receiving trough 351 formed in the front air outlet bottom wall 321 and a rear bottom water receiving trough 352 formed in the rear air outlet bottom wall 322. The rear air outlet bottom wall 322 is lower than the front air outlet bottom wall 321. Water in the front bottom water receiving trough 351 is suitable for flowing downward into the rear bottom water receiving trough 352, and water in the rear bottom water receiving trough 352 is suitable for flowing downward into the air duct water receiving trough 72. By making the rear air outlet bottom wall 322 lower than the front air outlet bottom wall 321, the water on the front air outlet bottom wall 321 can flow downwards into the rear air outlet bottom wall 322 under its own gravity. This allows the water in the front bottom water collection trough 351 to flow downwards into the rear air outlet bottom wall 322 under its own gravity, thus timely draining the condensate on the front air outlet bottom wall 321. Furthermore, by making the water in the rear bottom water collection trough 352 suitable for flowing downwards into the air duct water collection trough 72, the water accumulated in the rear bottom water collection trough 352 can be drained, preventing excessive water accumulation in the air duct water collection trough 72 from overflowing and causing danger.

[0088] For example, the first overflow nozzle 36 described above is located on the rear side of the rear air outlet bottom wall 322.

[0089] According to some embodiments of the present invention, with reference to Figure 16 A second overflow nozzle 37 is provided on the rear side of the front air outlet bottom wall 321, and the drain end of the second overflow nozzle 37 is located directly above the rear bottom water collection tank 352. By providing the second overflow nozzle 37 on the rear side of the front air outlet bottom wall 321, the condensate on the front air outlet bottom wall 321 can leave the front air outlet bottom wall 321 through the second overflow nozzle 37, which guides the flow of condensate. By placing the drain end of the second overflow nozzle 37 directly above the rear bottom water collection tank 352, the condensate flowing out of the second overflow nozzle 37 can drip into the rear bottom water collection tank 352 under its own gravity, preventing condensate from dripping onto other parts of the air conditioner and causing danger.

[0090] According to some embodiments of the present invention, with reference to Figure 16 The extension length of the second overflow nozzle 37 in the front-to-back direction is A, where A ≥ 3mm. For example, the value of A can be 3mm, 4mm, 5mm, 6mm, 7mm, etc. By ensuring that the extension length A of the second overflow nozzle 37 in the front-to-back direction is not less than 3mm, the second overflow nozzle 37 can guide the condensate water more effectively, and can more fully guide the condensate water from the rear side of the front air outlet bottom wall 321 to the rear bottom water receiving trough 352.

[0091] According to some embodiments of the present invention, with reference to Figure 16 The vertical distance between the second overflow nozzle 37 and the rear air outlet bottom wall 322 is B, where B ≥ 2mm. For example, the value of B can be 2mm, 3mm, 4mm, 5mm, 6mm, etc. By ensuring that the vertical distance B between the second overflow nozzle 37 and the rear air outlet bottom wall 322 is not less than 2mm, the position of the second overflow nozzle 37 relative to the rear air outlet bottom wall 322 can be made higher, and the height difference between the second overflow nozzle 37 and the rear air outlet bottom wall 322 can be more obvious, allowing the water on the front air outlet bottom wall 321 to flow downwards onto the rear air outlet bottom wall 322 under its own gravity more fully.

[0092] According to some embodiments of the present invention, with reference to Figure 16 The bottom surface of the front air outlet frame 13 is provided with a downwardly extending limiting rib 38, the second overflow nozzle 37 is located behind the limiting rib 38, the front edge of the rear bottom water receiving groove 352 is provided with an upwardly extending second water-blocking rib 39, the limiting rib 38 is located in front of the second water-blocking rib 39 and is arranged opposite to the limiting rib 38 in the front-rear direction. By providing a downwardly extending limiting rib 38 on the bottom surface of the front air outlet frame 13, the limiting rib 38 can position the assembly of the front air outlet frame 13 and the rear air outlet frame 14. When the limiting rib 38 abuts against the second water-blocking rib 39, the front air outlet frame 13 and the rear air outlet frame 14 are assembled in place, and the second overflow nozzle 37 is located behind the second water-blocking rib 39, preventing water from leaving the second overflow nozzle 37 and dripping forward to a position other than the rear bottom water receiving groove 352. By providing an upwardly extending second water-blocking rib 39 on the front edge of the rear bottom water receiving groove 352, the second water-blocking rib 39 can block and limit the water flow. To prevent condensate from flowing forward out of the rear bottom water collection tank 352, thus avoiding condensate dripping onto other components inside the air conditioner and causing a short circuit hazard, and also to prevent this condensate from dripping onto the floor and affecting the user experience; by positioning the limiting rib 38 in front of the second water-blocking rib 39 and opposite to the limiting rib 38 in the front-rear direction, the condensate flowing from the bottom surface of the front air outlet frame 13 to the rear bottom water collection tank 352 can be limited by the combined limiting effect of the limiting rib 38 and the second water-blocking rib 39, making the limiting rib 38 and the second water-blocking rib 39 more effective in limiting the condensate.

[0093] According to some embodiments of the present invention, with reference to Figure 23 and Figure 24The rear air outlet frame 14 is equipped with an air outlet frame baffle 47, and the air outlet end of the air outlet channel 11 is equipped with an air outlet grille 57. The air outlet frame baffle 47 is used to guide the airflow to the air outlet grille 57. By setting the air outlet frame baffle 47 in the air outlet channel 11, more airflow can be allowed to flow out from the air outlet 12, increasing the air volume of the air conditioner, increasing the temperature regulation capacity of the air conditioner, and reducing the airflow that is blown out from both sides of the air conditioner and is re-inhaled by the air inlet 64, thus reducing the short circuit of the air return air in the air conditioner.

[0094] Reference Figures 18-25 The outer wall surface of the air outlet frame baffle 47 is a first outer wall surface 48. The bottom of the first outer wall surface 48 is provided with a first water receiving part 49, which is higher than the front air outlet bottom wall 321. Water on the first water receiving part 49 is suitable for flowing downward into the front bottom water receiving groove 351. Since the inner wall surface of the air outlet frame baffle 47 is close to the air duct, the temperature of the air outlet frame baffle 47 itself is relatively low, and condensation water is easily formed on the first outer wall surface 48. By providing a first water-receiving part 49 at the bottom of the first outer wall surface 48, the condensate on the first outer wall surface 48 of the air outlet frame baffle 47 can flow along the first outer wall surface 48 under its own gravity and drip down to the first water-receiving part 49, thus preventing this part of the condensate from dripping onto other components inside the air conditioner and causing a short circuit hazard, and also preventing this part of the condensate from dripping onto the floor and affecting the user experience; by making the first water-receiving part 49 higher than the front air outlet bottom wall 321, the water on the first water-receiving part 49 can flow down into the front air outlet bottom wall 321 under its own gravity, thus timely draining the condensate on the first water-receiving part 49.

[0095] According to some embodiments of the present invention, with reference to Figures 17-24 A third overflow nozzle 50 is connected to the front side of the first water receiving part 49, and the drain end of the third overflow nozzle 50 is located directly above the front bottom water receiving groove 351. By connecting the third overflow nozzle 50 to the front side of the first water receiving part 49, the condensate on the front air outlet bottom wall 321 can leave the first water receiving part 49 through the third overflow nozzle 50, which guides the flow of condensate. By positioning the drain end of the third overflow nozzle 50 directly above the front bottom water receiving groove 351, the condensate flowing out of the third overflow nozzle 50 can drip into the front bottom water receiving groove 351 under its own gravity, preventing condensate from dripping onto other parts of the air conditioner and causing danger.

[0096] According to some embodiments of the present invention, with reference to Figures 18-24The outer wall of the rear air outlet frame 14 includes a second outer wall 41. The bottom of the second outer wall 41 is provided with a second water receiving part 42. The lower end of the second outer wall 41 is connected to the second water receiving part 42 and together define a rear water receiving trough 43. The rear water receiving trough 43 is located above the air duct water receiving trough 72. The water in the rear water receiving trough 43 is suitable for flowing downward into the air duct water receiving trough 72. By providing a second water receiving part 42 at the bottom of the second outer wall surface 41, the condensate on the second outer wall surface 41 of the rear air outlet frame 14 can flow along the second outer wall surface 41 under its own gravity and drip down to the second water receiving part 42, entering the rear water receiving trough 43. This avoids the condensate dripping onto other components inside the air conditioner, which could cause a short circuit hazard, and also prevents the condensate from dripping onto the floor, affecting the user experience. Since the rear water receiving trough 43 is located above the air duct water receiving trough 72, the water on the rear water receiving trough 43 can flow down into the air duct water receiving trough 72 under its own gravity, thus timely draining the condensate on the rear water receiving trough 43.

[0097] According to some embodiments of the present invention, with reference to Figures 18-22 The bottom wall of the rear water tank 43 is provided with a first overflow hole 44. The first overflow hole 44 is located at the rear end of the rear water receiving part and directly above the air duct water receiving tank 72. Water in the rear water tank 43 is suitable to flow downward into the air duct water receiving tank 72 through the first overflow hole 44. By providing the first overflow hole 44 on the bottom wall of the rear water tank 43, the condensate in the rear water tank 43 can leave the rear water tank 43 through the first overflow hole 44, and the condensate in the rear water tank 43 can be discharged in time. By placing the first overflow hole 44 directly above the air duct water receiving tank 72, the condensate flowing out of the first overflow hole 44 can drip into the air duct water receiving tank 72 under its own gravity, avoiding the condensate dripping onto other parts of the air conditioner and causing danger.

[0098] According to some embodiments of the present invention, with reference to Figures 18-22 A flow guiding structure 45 is provided on the second outer wall surface 41. The flow guiding structure 45 is used to guide the water on the second outer wall surface 41 downward to the rear water tank 43. By providing a flow guiding structure 45 on the second outer wall surface 41, the condensate on the second outer wall surface 41 can be guided by the flow guiding structure 45 and flow downward along the flow guiding structure 45 under its own gravity. This allows the condensate to flow downward to the rear water tank 43, preventing the condensate from dripping onto other parts of the air conditioner and causing danger.

[0099] For example, the rear air outlet frame 14 includes two second outer wall surfaces 41, which are spaced apart at the left and right ends of the rear air outlet frame 14. An air outlet channel 11 is formed inside the air outlet frame 10. The two second outer wall surfaces 41 are located on the left and right sides of the inlet end of the air outlet channel 11, respectively. A guide structure 45 is provided on both second outer wall surfaces 41.

[0100] According to some embodiments of the present invention, with reference to Figures 18-22 The flow guiding structure 45 includes a plurality of first flow guiding ribs 46 arranged in a vertical direction. The extension direction of the first flow guiding ribs 46 forms an angle with the vertical direction. In the direction from the second outer wall surface 41 to the free end of the first flow guiding rib 46, the first flow guiding rib 46 extends downward at an angle. By including a plurality of first flow guiding ribs 46 arranged in a vertical direction in the flow guiding structure 45, the condensate on the second outer wall surface 41 can be guided by the flow guiding structure 45 in the vertical direction, making the guiding effect of the flow guiding structure 45 on the condensate on the second outer wall surface 41 more sufficient. By making the first flow guiding ribs 46 extend downward at an angle in the direction from the second outer wall surface 41 to the free end of the first flow guiding rib 46, the first flow guiding rib 46 can guide the condensate in a downward direction, so that the condensate flows along the first flow guiding rib 46 and the second outer wall surface 41 and drips downward onto the second water receiving part 42, which can prevent excessive water accumulation on the second water receiving part 42.

[0101] According to some embodiments of the present invention, with reference to Figure 6 The top of the front air outlet frame 13 is provided with a first water receiving area 79, and the bottom wall of the first water receiving area 79 is provided with a second overflow hole 80. Water in the first water receiving area 79 is suitable to flow downward along the front air outlet frame 13 into the front bottom water receiving tank 351 through the second overflow hole 80. By providing a first water receiving area 79 at the top of the front air outlet frame 13, the first water receiving area 79 can receive the condensate stored on the top of the front air outlet frame 13, preventing this part of the condensate from dripping onto other parts of the air conditioner and causing danger. By providing a second overflow hole 80 on the bottom wall of the first water receiving area 79, the condensate in the first water receiving area 79 can flow downward along the front air outlet frame 13 into the front bottom water receiving tank 351 for collection under its own gravity, so as to discharge the condensate in the first water receiving area 79 in a timely manner.

[0102] According to some embodiments of the present invention, with reference to Figure 12 The outer wall of the front air outlet frame 13 is provided with a guide groove 40 extending vertically. The upper end of the guide groove 40 extends to the second overflow hole 80, and the lower end of the guide groove 40 extends to the front bottom water collection tank 351. By providing a guide groove 40 extending vertically on the outer wall of the front air outlet frame 13, the condensate flowing down from the second overflow hole 80 can flow downwards along the guide groove 40 under its own gravity, preventing this part of the condensate from dripping onto other parts of the air conditioner and causing danger. By extending the upper end of the guide groove 40 to the second overflow hole 80 and the lower end of the guide groove 40 to the front bottom water collection tank 351, the condensate is guided by the guide groove 40 from the time it leaves the second overflow hole 80 until it drips into the front bottom water collection tank 351, thus more fully guiding this part of the condensate to flow into the front bottom water collection tank 351 and preventing this part of the condensate from dripping onto other parts of the air conditioner and causing danger.

[0103] According to some embodiments of the present invention, with reference to Figures 5-10 The first water-collecting area 79 is located near the air outlet 12. Since the outer wall of the front air outlet frame 13 is close to the air outlet 12, this part is more prone to condensation. By setting the first water-collecting area 79 close to the air outlet 12, the first water-collecting area 79 can be closer to the part that is prone to condensation, and can collect the condensation more fully, avoiding this part of the condensation from dripping onto other parts of the air conditioner and causing danger.

[0104] According to some embodiments of the present invention, with reference to Figures 5-10 The second overflow hole 80 is located at one end of the first water receiving area 79 near the air outlet 12. Since the outer wall of the front air outlet frame 13 is close to the air outlet 12, this part is more prone to condensation. By setting the second overflow hole 80 at one end of the first water receiving area 79 near the air outlet 12, the second overflow hole 80 can be closer to the part that is prone to condensation, so that the second overflow hole 80 can drain the generated condensation more promptly.

[0105] According to some embodiments of the present invention, with reference to Figure 5 The air conditioner includes an air guide plate 51 and an air guide plate motor 511. The air guide plate 51 is rotatably mounted on the front air outlet frame 13 to open and close the air outlet 12. The air guide plate motor 511 is connected to the air guide plate 51 to drive the air guide plate 51 to rotate. The top of the front air outlet frame 13 has a motor mounting area 512, and the air guide plate motor 511 is mounted in the motor mounting area 512. A baffle rib 513 is provided between the motor mounting area 512 and the first water receiving area 79. Since the air guide plate motor 511 needs to be powered, when condensate comes into contact with the air guide plate motor 511, a short circuit or other danger may occur, or condensate entering the air guide plate motor 511 may damage the air guide plate motor 511. By providing a baffle rib 513 between the motor mounting area 512 and the first water receiving area 79, the baffle rib 513 can prevent condensate in the first water receiving area 79 from flowing into the motor mounting area 512, thereby improving the safety of the air conditioner.

[0106] According to some embodiments of the present invention, with reference to Figures 5-11The front panel 61 has a support plate 81 at its top. The support plate 81 is located above the front air outlet frame 13 and is connected to the front air outlet frame 13. The support plate 81 has a second water receiving area 82, and water in the second water receiving area 82 is suitable for flowing downward into the first water receiving area 79. By providing a support plate 81 at the top of the front panel 61, the support plate 81 allows the front panel 61 to be positioned downwards, making the installation process of the front panel 61 more convenient. Furthermore, by positioning the support plate 81 above the front air outlet frame 13 and connecting it to the front air outlet frame 13, the front air outlet frame 13 limits the position of the support plate 81, thereby improving the stability of the front panel 61 installation. For example, the support plate 81 can be used to place and support the front panel 61. Since part of the support plate 81 is close to the air outlet 12, the support plate 81 is prone to condensation. By providing a second water collection area 82 on the support plate 81, the condensation on the support plate 81 can be collected in the second water collection area 82, thus preventing the condensation on the support plate 81 from dripping onto other parts of the air conditioner and causing danger.

[0107] According to some embodiments of the present invention, with reference to Figures 5-11 The bottom wall of the second water receiving area 82 is provided with a third overflow hole 83, through which water in the second water receiving area 82 flows downward into the first water receiving area 79. By providing a third overflow hole 83 on the bottom wall of the second water receiving area 82, the condensate in the second water receiving area 82 can flow downward along the third overflow hole 83 under its own gravity, thus timely draining the condensate in the second water receiving area 82.

[0108] According to some embodiments of the present invention, with reference to Figures 5-11 The projection of the third overflow hole 83 onto the horizontal plane is at least partially offset from the projection of the second overflow hole 80 onto the horizontal plane. By offsetting the projection of the third overflow hole 83 onto the horizontal plane from the projection of the second overflow hole 80 onto the horizontal plane, the second water receiving area 82 and the first water receiving area 79 can form an alternating buffering effect. The water in the second water receiving area 82 first drips through the third overflow hole 83 to the first water receiving area 79, then converges with the water in the first water receiving area 79 and flows downward through the second overflow hole 80.

[0109] According to some embodiments of the present invention, with reference to Figures 5-11The housing assembly 60 includes a top cover 16, which covers the top of the front housing component 601 and the rear housing component 63. The upper surface of the top cover 16 has a top water collection groove 74, and the bottom wall of the top water collection groove 74 has a drain hole 75. Water in the top water collection groove 74 is suitable for flowing downwards into the second water collection area 82 through the drain hole 75. When the air conditioner is cooling, water vapor in the air near the upper surface of the top cover 16 easily condenses, and the condensed water adheres to the upper surface of the top cover 16. By providing a top water collection groove 74 on the upper surface of the top cover 16, the condensed water on the upper surface of the air conditioner's top cover 16 can be concentrated in the top water collection groove 74, avoiding or reducing the inconvenience caused to the user by condensed water dripping downwards from the outer edge of the top cover 16 onto the ground. By providing a drain hole 75 on the bottom wall of the top water receiving tank 74, the water in the top water receiving tank 74 can flow downward into the housing assembly 60 through the drain hole 75, so that the water in the top water receiving tank 74 can be discharged in time, and excessive water accumulation in the top water receiving tank 74 can be avoided from overflowing.

[0110] According to some embodiments of the present invention, with reference to Figures 5-11 The top water collection trough 74 is located at the front of the top cover 16, and the drain hole 75 is located at the front end of the top water collection trough 74. Since the front part of the top cover 16 is closer to the air outlet 12, the temperature is lower at the front part of the top cover 16, and condensation is more likely to occur there. By placing the top water collection trough 74 at the front of the top cover 16 and the drain hole 75 at the front end of the top water collection trough 74, the top water collection trough 74 and the drain hole are closer to the part that is prone to condensation, and the drain hole can discharge the condensation more promptly.

[0111] For example, the projection of the drain hole 75 onto the horizontal plane is at least partially offset from the projection of the third overflow hole 83 onto the horizontal plane. This allows the top water receiving tank 74 and the second water receiving area 82 to form an alternating buffering effect, whereby water in the top water receiving tank 74 first drips through the drain hole 75 into the second water receiving area 82, then converges with the water in the second water receiving area 82 and flows downward through the third overflow hole 83.

[0112] According to some embodiments of the present invention, the sidewall of the air outlet 12 includes an air outlet sidewall 59, which extends vertically to the air outlet bottom wall 32. A guide groove 401 extending vertically is formed on the air outlet sidewall 59, and the lower end of the guide groove 401 extends downward to the bottom water collection tank 35. By forming a guide groove 401 extending vertically on the air outlet sidewall 59, and by placing the guide groove 401 close to the air outlet 12, condensate can preferentially form within the guide groove 401, preventing condensate formed on the front casing 62 of the air conditioner from dripping onto the ground. Furthermore, the guide groove 401 guides water flow; by extending the lower end of the guide groove 401 downward to the bottom water collection tank 35, the condensate within the guide groove 401 can flow downward along the guide groove 401 to the bottom water collection tank 35 under its own gravity, preventing condensate from dripping onto the ground and causing inconvenience to the user.

[0113] According to some embodiments of the present invention, with reference to Figures 5-11 The lower surface of the top cover 16 is provided with a guide pipe 77. The guide pipe 77 surrounds the outer periphery of the drain hole 75 and is close to the rear edge of the second water receiving area 82. A guide slope 771 is formed at the bottom of the guide pipe 77. The guide slope 771 extends downward in a front-to-back direction. By having the guide pipe 77 surround the outer periphery of the drain hole 75 and close to the rear edge of the second water receiving area 82, the water flowing downward from the guide pipe 77 can be blocked by the rear edge of the second water receiving area 82, preventing the water flowing from the guide pipe 77 from dripping outside the second water receiving area 82 and onto other components inside the air conditioner. Since the rear side of the guide pipe 77 is closer to the rear edge, by having the guide slope 771 extend downward in a front-to-back direction, the side wall of the guide pipe 77 and the rear edge can work together to block the water flowing downward from the guide pipe 77, more effectively preventing the water flowing from the guide pipe 77 from dripping outside the second water receiving area 82 and onto other components inside the air conditioner.

[0114] According to some embodiments of the present invention, with reference to Figures 5-8 The upper surface of the top cover 16 is provided with an annular anti-overflow rib 741, and the inner circumference of the anti-overflow rib 741 defines a top water receiving groove 74. By providing an annular anti-overflow rib 741 on the upper surface of the top cover 16, it is convenient to form a top water receiving groove 74 on the upper surface of the top cover 16, and the structural strength of the top cover 16 can be enhanced. The anti-overflow rib 741 can serve as the edge of the top water receiving groove 74, blocking water on the top cover 16 and preventing this water from dripping down the outer edge of the top cover 16 onto the ground.

[0115] According to some embodiments of the present invention, with reference to Figures 5-10The bottom wall of the top water receiving tank 74 is provided with a drain hole 75, which is used to guide the water in the top water receiving tank 74 downward into the housing assembly 60. By providing a drain hole 75 on the bottom wall of the top water receiving tank 74, the water in the top water receiving tank 74 can flow downward into the housing assembly 60 through the drain hole 75, which can allow the water in the top water receiving tank 74 to be discharged in a timely manner, and prevent excessive water accumulation and overflow in the top water receiving tank 74.

[0116] According to some embodiments of the present invention, with reference to Figures 5-10 The bottom wall of the top water receiving tank 74 has a flow-guiding slope 76. The flow-guiding slope 76 is located on the outer periphery of the drain hole 75 and extends to the edge of the drain hole 75. The flow-guiding slope 76 extends downward at an angle close to the center of the drain hole 75. By forming the flow-guiding slope 76 on the bottom wall of the top water receiving tank 74 and extending it downward at an angle close to the center of the drain hole 75, the water in the top water receiving tank 74 can flow downward along the flow-guiding slope 76 under its own gravity. The flow-guiding slope 76 can guide the water in the top water receiving tank 74 into the drain hole 75, thus allowing the water in the top water receiving tank 74 to be discharged in a timely manner and preventing excessive water accumulation and overflow.

[0117] According to some embodiments of the present invention, the air conditioner includes a drip tray disposed within the housing assembly 60 and located below the heat exchange and air supply assembly 65. For example, the drip tray may be located below the heat exchanger assembly 651. Water drained into the housing assembly 60 through the drain hole 75 is suitable for draining into the drip tray through the air duct assembly 69. When the air conditioner is cooling, condensate generated on the heat exchanger assembly 651 can flow downwards into the drip tray, and condensate generated on the air duct assembly 69 can also flow downwards into the drip tray. By including a drip tray in the air conditioner and draining water from the top cover 16 into the housing assembly 60 through the drain hole 75 and into the drip tray through the air duct assembly 69, the condensate flowing down from the top cover 16 can be collected and gathered in the drip tray, preventing this condensate from dripping onto other components inside the air conditioner and causing a short circuit hazard, and also preventing this condensate from dripping onto the ground.

[0118] According to some embodiments of the present invention, with reference to Figure 5 and Figure 6The housing assembly 60 includes a front housing component 601 and a rear housing component 63 connected front to back. The front housing component 601 is connected to the front side of the rear housing component 63. A top cover 16 covers the top of the front housing component 601 and the rear housing component 63. An air outlet 12 is formed in the front housing component 601, and an air inlet 64 is formed in the rear housing component 63. The top cover 16 includes a front cover portion 23 and a rear cover portion 24. The front cover portion 23 is connected to the front side of the rear cover portion 24 and covers the top of the front housing component 601. The rear cover portion 24 covers the top of the rear housing component 63. A top water collection groove 74 is provided on the upper surface of the front cover portion 23. Because the front cover portion 23 of the top cover 16 is closer to the air outlet 12, the temperature of the front cover portion 23 is relatively low, and condensation is more likely to form on the front cover portion 23 of the air conditioner. By providing a top water collection groove 74 on the upper surface of the front cover 23, the top water collection groove 74 can be placed closer to the part that is prone to condensation, so that the top water collection groove 74 can fully collect the condensation generated by the top cover 16.

[0119] According to some embodiments of the present invention, with reference to Figures 5-8 The upper surface of the front cover 23 is provided with an annular anti-overflow rib 741. The anti-overflow rib 741 is close to the outer periphery of the front cover 23 and extends circumferentially along the front cover 23. The inner periphery of the anti-overflow rib 741 defines the top water receiving groove 74. Since the front cover 23 of the top cover 16 is close to the air outlet 12, the temperature of the front cover 23 is relatively low, and condensation is more likely to form on the front cover 23 of the air conditioner. By providing an annular anti-overflow rib 741 on the upper surface of the front cover 23, it is convenient to form the top water receiving groove 74 on the upper surface of the top cover 16, and the structural strength of the top cover 16 can be enhanced. The anti-overflow rib 741 can serve as the edge of the top water receiving groove 74, more effectively blocking water located in the front cover 23, and more effectively preventing this water from dripping down from the outer edge of the top cover 16 onto the ground.

[0120] According to some embodiments of the present invention, with reference to Figures 5-10 The bottom wall of the top water receiving tank 74 is provided with a drain hole 75, which is used to guide the water in the top water receiving tank 74 downward into the front housing component 601. By providing a drain hole 75 on the bottom wall of the top water receiving tank 74, the water in the top water receiving tank 74 is suitable to flow downward into the front housing component 601 through the drain hole 75, so that the water stored in the top water receiving tank 74 can be discharged in time, and excessive water accumulation in the top water receiving tank 74 can be avoided from overflowing.

[0121] According to some embodiments of the present invention, with reference to Figures 5-10The drain hole 75 is located at the front end of the front cover 23 and / or near the air outlet 12. For example, the drain hole 75 is located at the front end of the front cover 23; for example, the drain hole 75 is near the air outlet 12; and for yet another example, the drain hole 75 is located at the front end of the front cover 23 and near the air outlet 12. Since the front end of the front cover 23 is closer to the air outlet 12, the temperature at the front end of the front cover 23 is lower when the air conditioner is in cooling mode, and condensation is more likely to form at the front end of the front cover 23. By placing the drain hole 75 at the front end of the front cover 23 and / or near the air outlet 12, the drain hole 75 can be closer to the part that is prone to condensation, allowing the drain hole 75 to drain the condensation more promptly.

[0122] According to some embodiments of the present invention, with reference to Figures 5-8 The front housing component 601 includes an air outlet frame assembly 101, which forms an air outlet channel 11. The air outlet end of the air outlet channel 11 forms an air outlet 12. The front cover portion 23 is connected to the top of the air outlet frame assembly 101. A top water receiving area 78 is formed on the top of the air outlet frame assembly 101. Water in the top water receiving tank 74 is suitable for being drained downwards through the drain hole 75 to the top water receiving area 78. By forming a top water receiving area 78 on the top of the air outlet frame assembly 101, the top water receiving area 78 can receive condensate water that has liquefied and formed on the top of the front air outlet frame 13, preventing this condensate water from dripping onto other components of the air conditioner and causing danger. Furthermore, the condensate water in the top water receiving tank 74 can flow downwards along the drain hole 75 under its own gravity and collect in the top water receiving area 78, so that the condensate water in the top water receiving tank 74 can be discharged in a timely manner.

[0123] According to some embodiments of the present invention, with reference to Figures 12-14 The air conditioner also includes a water collection tray, which is located inside the housing assembly 60 and below the heat exchange and air supply assembly 65. The bottom wall of the air outlet duct 11 is the air outlet bottom wall 32, and the air outlet bottom wall 32 forms a bottom water collection trough 35. The water in the top water collection area 78 is suitable for flowing downward along the air outlet frame assembly 101 to the bottom water collection trough 35. The bottom of the air duct assembly 69 is provided with an air duct water collection trough 72. The water in the bottom water collection trough 35 is suitable for flowing backward to the air duct water collection trough 72, and the water in the air duct water collection trough 72 is suitable for flowing downward into the water collection tray. By allowing the water in the top water receiving area 78 to flow downwards along the air outlet frame assembly 101 to the bottom water receiving trough 35, and the bottom of the air duct assembly 69 is provided with an air duct water receiving trough 72, the condensate in the top water receiving area 78 can flow downwards to the bottom wall 32 of the air outlet under its own gravity, and the condensate in the bottom water receiving trough 35 of the bottom wall 32 of the air outlet can flow into the air duct water receiving trough 72 of the bottom wall of the air duct under its own gravity, so that the condensate in the top water receiving area 78 and the bottom water receiving trough 35 can be discharged in time, and the excessive condensate in the top water receiving area 78 and the bottom water receiving trough 35 can be avoided from overflowing.

[0124] According to some embodiments of the present invention, the water receiving tray is located below the heat exchange and air supply assembly 65, and the water in the duct water receiving tank 72 is adapted to flow downward into the water receiving tray. By positioning the water receiving tray below the heat exchange and air supply assembly 65, the water in the duct water receiving tank 72 can flow downward into the water receiving tray under its own gravity, thus timely draining the condensate in the duct water receiving tank 72 and preventing excessive condensate from overflowing and causing danger.

[0125] According to some embodiments of the present invention, with reference to Figures 22-26 The air outlet frame assembly 101 includes an air outlet frame 10 and a front panel 61. The air outlet frame 10 forms an air outlet channel 11. The front panel 61 is connected to the front side of the air outlet frame 10. A support plate 81 is formed on the top of the front panel 61. The support plate 81 is located on the upper side of the air outlet frame 10 and connected to the air outlet frame 10. The top water receiving area 78 includes a first water receiving area 79 and a second water receiving area 82. The top of the air outlet frame 10 forms a first water receiving area 79. The upper surface of the support plate 81 forms a second water receiving area 82. The bottom wall of the first water receiving area 79 forms a second overflow hole 80. The bottom wall of the second water receiving area 82 forms a third overflow hole 83. The water in the second water receiving area 82 is adapted to flow downward through the third overflow hole 83 to the first water receiving area 79. The water in the first water receiving area 79 is adapted to flow downward along the air outlet frame 10 to the bottom water receiving trough 35 through the second overflow hole 80. Condensate in the top water receiving trough 74 or water falling into the top water receiving trough 74 flows into the second water receiving area 82 through the drain hole 75, where it merges with the condensate in the second water receiving area 82. Water in the second water receiving area 82 drips into the first water receiving area 79 through the third overflow hole 83, where it merges with the condensate in the first water receiving area 79. Condensate in the first water receiving area 79 flows downward along the air outlet frame 10 through the second overflow hole 80 to the bottom water receiving trough 35. This allows the water in the top water receiving area 78 to be discharged in a timely manner, preventing excessive water accumulation in the top water receiving area 78.

[0126] According to some embodiments of the present invention, with reference to Figure 7 The top cover 16 includes a top cover body 17 and a first flange 18, which is connected to the outer periphery of the top cover body 17 and extends downward. By including the first flange 18 in the top cover 16, which is connected to the outer periphery of the top cover body 17 and extends downward, when the top cover 16 needs to cooperate with other components located below the top cover 16, the first flange 18 is close to other components and does not affect the structure of the top cover body 17, making it easier for the top cover 16 to cooperate and connect with other components.

[0127] Furthermore, referring to Figure 7The lower surface of the top cover body 17 is provided with a first reinforcing structure 19. The first reinforcing structure 19 is closer to the outer periphery of the top cover body 17 than the middle part of the top cover body 17, and the first reinforcing structure 19 is connected to the first flange 18. By making the first reinforcing structure 19 closer to the outer periphery of the top cover body 17 than the middle part of the top cover body 17, the first reinforcing structure 19 can be closer to the first flange 18, so as to facilitate the connection between the first reinforcing structure 19 and the first flange 18. By connecting the first reinforcing structure 19 to the first flange 18, the first reinforcing structure 19 can strengthen the structural strength of the first flange 18, avoid deformation of the first flange 18 which would cause gaps when the first flange 18 is fitted with other components, and reduce assembly difficulty.

[0128] According to some embodiments of the present invention, with reference to Figure 7 The lower surface of the rear cover 24 is provided with a first connecting structure 25, which is connected to the rear shell component 63. The first reinforcing structure 19 includes a first reinforcing rib structure 20, which is connected to the first connecting structure 25 and the first flange 18 and together forms an enclosure for at least one reinforcing cavity 28. For example, the first connecting structure 25 can be a cylindrical groove to facilitate the connection and fixation of the top cover 16 to other components by fasteners. By connecting the first reinforcing rib structure 20 to the first connecting structure 25 and the first flange 18 and together forming an enclosure for at least one reinforcing cavity 28, the first reinforcing rib structure 20 can make the connection between the first flange 18 and the first connecting structure 25 more complete, while increasing the structural strength of the first flange 18 and the first connecting structure 25 and reducing the deformation of the first flange 18 and the first connecting structure 25; and, it can appropriately reduce the use of materials and reduce costs.

[0129] According to some embodiments of the present invention, with reference to Figure 7 There are multiple reinforcing cavities 28, which are spaced apart circumferentially along the first flange 18. The first reinforcing rib structure 20 includes multiple sets of first reinforcing rib groups 21, each set of first reinforcing rib groups 21 including multiple first reinforcing ribs 22. The number of first reinforcing rib groups 21 and reinforcing cavities 28 are the same and correspond one-to-one. Each reinforcing cavity 28 is jointly enclosed by the corresponding first reinforcing rib group 21, the first connecting structure 25, and the first flange 18. By having multiple reinforcing cavities 28, which are spaced apart circumferentially along the first flange 18, the first flange 18 can be reinforced by the reinforcing cavities 28 in the circumferential direction, making the reinforcement effect of the reinforcing cavities 28 on the first flange 18 more sufficient. By having each set of first reinforcing rib groups 21 include multiple first reinforcing ribs 22, and each reinforcing cavity 28 is jointly enclosed by the corresponding first reinforcing rib group 21, the first connecting structure 25, and the first flange 18, the reinforcement effect of the reinforcing cavities 28 on the first flange 18 can be made more sufficient.

[0130] For example, there can be two or three reinforcing cavities 28.

[0131] For example, each group of first reinforcing ribs 21 may include one, two, three, etc., first reinforcing ribs 22.

[0132] According to some embodiments of the present invention, with reference to Figure 7 The first connecting structure 25 includes multiple first connecting posts 26 and multiple first pins 27. The multiple first connecting posts 26 and multiple first pins 27 are spaced apart circumferentially along the first flange 18. Each reinforcing cavity 28 is jointly enclosed by a corresponding first reinforcing rib group 21, a first connecting post 26, a first pin 27, and a first flange 18. By arranging the multiple first connecting posts 26 and multiple first pins 27 spaced apart circumferentially along the first flange 18, the top cover 16 can be connected and fixed by the first pins 27 and / or the first connecting posts 26 in the circumferential direction of the first flange 18 when connected to other components, making the connection between the top cover 16 and other components more complete and preventing the top cover 16 from falling off. By having each reinforcing cavity 28 enclosed by the corresponding first reinforcing rib group 21, first connecting post 26, first pin 27 and first flange 18, the reinforcing effect of the reinforcing cavity 28 on the first flange 18 can be more sufficient; and the first reinforcing rib group 21 can increase the structural strength of the first pin 27 and the first connecting post 26.

[0133] For example, the first connecting post 26 can be one, two, three, etc.

[0134] For example, the first pin 27 can be one, two, three, etc.

[0135] For example, the first connecting post 26 is provided with a connecting hole. When the top cover 16 is connected with other components, fasteners are inserted through the connecting hole to connect the top cover 16 with other components.

[0136] According to some embodiments of the present invention, with reference to Figure 7The first pin 27 is connected to the first flange 18. A first reinforcing rib 22 connects the first connecting post 26 to the first flange 18 for each reinforcing cavity 28, and a first reinforcing rib 22 connects the first connecting post 26 to the first pin 27 for each reinforcing cavity 28. By connecting the first pin 27 to the first flange 18, the first pin 27 can not only connect the top cover 16 to other components but also reinforce the first flange 18, thus preventing deformation of the first flange 18. The connection between the first connecting post 26 and the first pin 27 for each reinforcing cavity 28 and the first reinforcing rib 22 makes the connection between the first connecting post 26, the first pin 27, and the first flange 18 more secure. Furthermore, after arranging the positions of the first pin 27 and the first connecting post 26 according to the connection points of other components, the first reinforcing rib 22 can be directly set to connect the first connecting post 26 and the first pin 27, making it easier to set the shape of the reinforcing cavity 28.

[0137] According to some embodiments of the present invention, with reference to Figure 7 The first pin 27 and the first flange 18 are connected by multiple first connecting ribs, which are arranged at intervals along the circumference of the first flange 18. By connecting the first pin 27 and the first flange 18 with multiple first connecting ribs, the connection between the first pin 27 and the first flange 18 is made more reliable. Furthermore, by arranging the multiple first connecting ribs at intervals along the circumference of the first flange 18, the first flange 18 is reinforced in the circumferential direction by the connecting ribs, thus making the reinforcement effect of the first connecting ribs more comprehensive.

[0138] According to some embodiments of the present invention, with reference to Figure 7Multiple first connecting posts 26 are distributed at the front end and the middle of the rear side of the rear cover 24. The first connecting post 26 at the front end of the rear cover 24, together with the first pin 27, the first reinforcing rib group 21, and the first flange 18, forms a reinforcing cavity 28. A connecting beam 29 connects the first connecting post 26 at the middle of the rear side of the rear cover 24 and the first flange 18, and the connecting beam 29 extends in the front-rear direction. By distributing multiple first connecting posts 26 at the front end and the middle of the rear side of the rear cover 24, the connection between the cover and other components can be made more sufficient. Since the flange at the front end of the rear cover 24 is more prone to deformation, by having the first connecting post 26 at the front end of the rear cover 24, together with the first pin 27, the first reinforcing rib group 21, and the first flange 18, form a reinforcing cavity 28, the reinforcing cavity 28 can strengthen this area and more effectively prevent deformation of the flange at the front end of the rear cover 24. By connecting a connecting beam 29 between the first connecting post 26 located in the middle of the rear side of the rear cover 24 and the first flange 18, the connecting beam 29 can strengthen the flange located in the middle of the rear side of the rear cover 24, prevent the flange from deforming, and make the connection between the flange and the top cover body 17 more complete.

[0139] According to some embodiments of the present invention, with reference to Figure 7 In the direction from back to front, the length of the first flange 18 gradually increases in the vertical direction, and at least part of the reinforcing cavity 28 is located at the front end of the rear cover 24. Since the first flange 18 near the front end of the rear cover 24 is longer, this part of the first flange 18 is more prone to deformation. By placing at least part of the reinforcing cavity 28 at the front end of the rear cover 24, the more easily deformable part of the first flange 18 can be reinforced by the reinforcing cavity 28, reducing the deformation of this part of the first flange 18. This makes the assembly error of the first flange 18 smaller and easier to assemble when it is assembled with other components.

[0140] According to some embodiments of the present invention, with reference to Figure 7 Multiple reinforcing ribs 30 are provided at the connection between the first flange 18 and the rear cover 24, and these reinforcing ribs 30 are spaced apart circumferentially along the first flange 18. By providing multiple reinforcing ribs 30 at the connection between the first flange 18 and the rear cover 24, the thickness of this part can be increased, strengthening the structural strength of the first flange 18 and ensuring a more complete connection between the first flange 18 and the rear cover 24. By arranging the multiple reinforcing ribs 30 at circumferential intervals along the first flange 18, the first flange 18 is subjected to the reinforcing structural strength of the reinforcing ribs 30 in the circumferential direction, thus strengthening the connection between the first flange 18 and the rear cover 24 and more effectively preventing fitting errors when the first flange 18 is deformed and mated with other components.

[0141] According to some embodiments of the present invention, with reference to Figure 7 The lower surface of the front cover portion 23 is provided with a second reinforcing structure 31, which includes a plurality of connected second reinforcing ribs, each of which is polygonal and annular. By providing the second reinforcing structure 31 on the lower surface of the front cover portion 23, the structural strength of the front cover portion 23 can be increased and the deformation of the front cover portion 23 can be reduced. By making the second reinforcing structure 31 include a plurality of connected second reinforcing ribs, each of which is polygonal and annular, the second reinforcing ribs can increase the thickness of this part of the top cover 16, thereby increasing the structural strength of the front cover portion 23 and reducing the amount of material used, thus reducing costs.

[0142] For example, multiple second reinforcing ribs are arranged in a honeycomb pattern. By arranging multiple second reinforcing ribs in a honeycomb pattern, the distribution is uniform and easy to lay.

[0143] According to some embodiments of the present invention, the front housing component 601 includes a front housing 62 and an air outlet frame assembly 101. The air outlet frame assembly 101 is mounted on the front housing 62 and forms an air outlet channel 11. The air outlet end of the air outlet channel 11 constitutes an air outlet 12. The front cover portion 23 is connected to the top of the air outlet frame assembly 101 and the top of the front housing 62. The upper end of the front housing 62 mates with the first flange 18 in the front-rear direction. By mates the upper end of the front housing 62 with the first flange 18 in the front-rear direction, the side of the air conditioner can be fitted tightly, the sealing performance of the side wall of the air conditioner is better, and gaps between the upper end of the front housing 62 and the first flange 18 are avoided, which would lead to air leakage and a reduction in the air volume of the air conditioner. Furthermore, the side wall of the air conditioner can be made to appear as a single unit.

[0144] According to some embodiments of the present invention, with reference to Figures 25-30 The air conditioner includes an air guide plate 51, which is rotatably mounted on the front air outlet frame 13 to open and close the air outlet 12. Multiple air diffusers 52 are formed on the air guide plate 51, extending through it along its thickness. The air guide plate 51 is located above the bottom water receiving tank 35. By forming multiple air diffusers 52 on the air guide plate 51, extending through it along its thickness, airflow can be directed out through these diffusers 52 when the air guide plate 51 is closed, achieving a draft-free effect and avoiding the discomfort caused by direct airflow. When the air conditioner is in cooling mode, condensation is easily generated on the air guide plate 51. By positioning the air guide plate 51 above the bottom water collection tank 35, the condensation on the air guide plate 51 can flow downward along the air guide plate 51 under its own gravity and be collected by the bottom water collection tank 35, thus preventing the condensation on the air guide plate 51 from dripping onto other parts of the air conditioner and causing danger.

[0145] According to some embodiments of the present invention, with reference to Figures 25-30When the air guide plate 51 is in the closed position of the air outlet 12, the surface of the air guide plate 51 facing outward from the housing assembly 60 is the outer side 53. The lower end of the outer side 53 is formed as a guide surface 54, which is used to guide the condensate on the outer side 53 downward into the bottom water collection tank 35. When the air conditioner is in the start-up state, the air guide plate 51 itself is at a low temperature and the outer side 53 is far away from the air duct, making it easier for condensate to form on the outer side 53. By making the lower end of the outer side 53 into a guide surface 54, the condensate can be guided downward into the bottom water collection tank 35 more effectively, and the condensate on the air guide plate 51 can be more effectively prevented from dripping onto other parts of the air conditioner and causing danger.

[0146] According to some embodiments of the present invention, with reference to Figures 25-30 When the air guide plate 51 is in the position where the air outlet 12 is closed, the guide surface 54 extends at an angle from top to bottom toward the interior of the housing assembly 60. By extending the guide surface 54 at an angle from top to bottom toward the interior of the housing assembly 60, the condensate on the air guide plate 51 can flow downward along the guide surface 54 under its own gravity, gradually moving toward the interior of the housing assembly 60, thus getting closer to the bottom water collection tank 35. This allows the condensate on the air guide plate 51 to be guided more effectively into the bottom water collection tank 35, and more effectively prevents the condensate on the air guide plate 51 from dripping onto other parts of the air conditioner and causing danger.

[0147] According to some embodiments of the present invention, with reference to Figures 25-30 When the air guide plate 51 is in the closed position of the air outlet 12, the projection of the lower edge of the guide surface 54 on the horizontal plane is located within the projection of the bottom water collection tank 35 on the horizontal plane. By making the projection of the lower edge of the guide surface 54 on the horizontal plane located within the projection of the bottom water collection tank 35 on the horizontal plane, the condensate on the air guide plate 51 can flow downward along the guide surface 54 under its own gravity, leave the guide surface 54 from the lower edge of the guide surface 54 and drip into the bottom water collection tank 35. This can more effectively guide the condensate on the air guide plate 51 into the bottom water collection tank 35, and more effectively prevent the condensate on the air guide plate 51 from dripping onto other parts of the air conditioner and causing danger.

[0148] According to some embodiments of the present invention, with reference to Figures 25-30The air conditioner includes a sealing strip 58, and the side wall of the air outlet 12 of the sealing strip 58 includes an air outlet side wall 59. The air outlet side wall 59 extends along the rotation axis of the air guide plate 51, and the sealing strip 58 is provided on the air outlet side wall 59. By providing the sealing strip 58 on the air outlet side wall 59 of the air conditioner, the side of the air guide plate 51 can be separated from the air outlet side wall 59. This can avoid friction and wear caused by direct contact between the air guide plate 51 and the air outlet side wall 59. Furthermore, when the air guide plate 51 closes the air outlet 12, the sealing strip 58 can effectively seal the gap between the air guide plate 51 and the air outlet side wall 59.

[0149] According to some embodiments of the present invention, the hardness of the sealing strip 58 is less than the hardness of the housing assembly 60. By making the hardness of the sealing strip 58 less than the hardness of the housing assembly 60, when the air guide plate 51 contacts and seals with the sealing strip 58, the air guide plate 51 compresses the sealing strip 58, resulting in a more complete sealing effect; and by making the hardness of the sealing strip 58 lower, the wear generated by the air guide plate 51 when it mates with the sealing strip 58 can be reduced.

[0150] According to some embodiments of the present invention, with reference to Figures 25-30 The sealing strip 58 is snapped and fixed to the side wall of the air outlet 12. By snapping the sealing strip 58 to the side wall of the air outlet 12, the installation and fixing of the sealing strip 58 is convenient, and this installation and fixing method is simple and reliable.

[0151] According to some embodiments of the present invention, with reference to Figures 25-30 When the air guide plate 51 is in the closed position of the air outlet 12, the side wall of the air guide plate 51 contacts the sealing strip 58. By making the side wall of the air guide plate 51 contact the sealing strip 58 when the air outlet 12 is closed, the friction and wear generated during the mating of the side wall of the air guide plate 51 and the air outlet side wall 59 are reduced; and by making the side wall of the air guide plate 51 contact the sealing strip 58, the seal between the air guide plate 51 and the sealing strip 58 can be more complete when the air guide plate 51 is in the closed state, preventing water or dust from entering the air conditioner.

[0152] For example, the air guide plate 51 is provided with multiple air vents 52. The air conditioner has a windless mode. When the air conditioner is in the windless mode, the air guide plate 51 is in a closed state, and the side wall of the air guide plate 51 is in contact with the sealing strip 58. By making the side wall of the air guide plate 51 in contact with the sealing strip 58, the sealing effect between the air guide plate 51 and the sealing strip 58 can be more complete, avoiding air leakage between the side wall of the air guide plate 51 and the sealing strip 58, which would reduce the windless effect.

[0153] According to some embodiments of the present invention, with reference to Figures 25-30The housing assembly 60 includes an air outlet frame assembly 101, which forms an air outlet channel 11. The air outlet end of the air outlet channel 11 forms an air outlet 12. The rotation axis of the air guide plate 51 extends vertically. A bottom water collection groove 35 is formed on the bottom wall of the air outlet channel 11, and a sealing strip 58 is located above the bottom water collection groove 35. When the air conditioner is in cooling mode, condensation easily forms on the sealing strip 58. By positioning the sealing strip 58 above the bottom water collection groove 35, the condensation on the sealing strip 58 can flow downwards along the sealing strip 58 under its own gravity and be collected by the bottom water collection groove 35, preventing the condensation on the sealing strip 58 from dripping onto the ground.

[0154] According to some embodiments of the present invention, with reference to Figures 25-30 Multiple air diffusers 52 are formed on the air guide plate 51, and the air diffusers 52 penetrate the air guide plate 51 along its thickness direction. By forming multiple air diffusers 52 on the air guide plate 51, and having the air diffusers 52 penetrate the air guide plate 51 along its thickness direction, when the air guide plate 51 is in the closed state, airflow can be blown out from the multiple air diffusers 52, achieving a windless effect and avoiding the discomfort caused by direct airflow.

[0155] According to some embodiments of the present invention, with reference to Figures 25-30 The sealing strip 58 has a contact surface 591. When the air guide plate 51 is in the closed position of the air outlet 12, the side wall of the air guide plate 51 contacts the contact surface 591. The projection of the contact surface 591 on the horizontal plane is located within the projection of the bottom water collection groove 35 on the horizontal plane. By making the sealing strip 58 have a contact surface 591 and making the side wall of the air guide plate 51 contact the contact surface 591 when the air outlet 12 is closed, the sealing effect between the sealing strip 58 and the air guide plate 51 can be more complete; and the wear of the air guide plate 51 when the sealing strip 58 and the air guide plate 51 are in contact can be reduced more effectively. By making the projection of the contact surface 591 on the horizontal plane located within the projection of the bottom water collection groove 35 on the horizontal plane, the condensate on the contact surface 591 can flow downward along the sealing strip 58 under its own gravity and be collected by the bottom water collection groove 35, preventing the condensate on the contact part from dripping onto the ground.

[0156] According to some embodiments of the present invention, with reference to Figures 25-30 The air guide plate 51 is located above the bottom water collection tank 35. By positioning the air guide plate 51 above the bottom water collection tank 35, the condensate on the air guide plate 51 can flow downward along the air guide plate 51 under its own gravity and be collected by the bottom water collection tank 35, thus preventing the condensate on the air guide plate 51 from dripping onto the ground.

[0157] When the air guide plate 51 is in the position where the air outlet 12 is closed, refer to Figures 25-30The surface of the air guide plate 51 facing outward from the housing assembly 60 is the outer side 53. The lower end of the outer side 53 is formed as a guide surface 54, which guides the condensate on the outer side 53 downward into the bottom water collection tank 35. By forming the lower end of the outer side 53 as a guide surface 54, when the condensate on the outer side 53 gathers and flows downward, the guide surface 54 can guide the condensate, causing it to gather and drip into the bottom water collection tank 35, facilitating the collection of condensate and preventing it from dripping onto the ground, thus improving the user experience.

[0158] According to some embodiments of the present invention, with reference to Figures 25-30 When the air guide plate 51 is in the position where the air outlet 12 is closed, the guide surface 54 extends at an angle from top to bottom toward the inside of the housing assembly 60. By extending the guide surface 54 at an angle from top to bottom toward the inside of the housing assembly 60, the guide surface 54 can guide the condensate more effectively. When the condensate passes through the guide surface 54 from top to bottom under its own gravity, it can flow from the outside to the inside along the inclined guide surface 54 until the condensate gathers and drips onto the bottom wall 32 of the air outlet.

[0159] According to some embodiments of the present invention, with reference to Figure 28 The guide surface 54 extends along an arc-shaped trajectory in the vertical direction. By extending the guide surface 54 along an arc-shaped trajectory in the vertical direction, it is possible to prevent personnel from being cut by the corners of the guide surface 54 when moving the air conditioner; furthermore, it allows for a natural transition of the downward slope of the guide surface 54, enabling more effective guidance of condensate water. The condensate water can flow downwards along the arc-shaped guide surface 54, preventing it from dripping directly downwards.

[0160] According to some embodiments of the present invention, with reference to Figures 25-30 When the air guide plate 51 is in the closed position of the air outlet 12, the projection of the lower edge of the guide surface 54 on the horizontal plane is within the projection of the bottom water collection tank 35 on the horizontal plane. This allows the guide surface 54 to more effectively divert condensate water, causing it to drip onto the bottom water collection tank 35 and preventing it from dripping onto the outside of the tank, thus improving the user experience.

[0161] According to some embodiments of the present invention, with reference to Figures 25-30The bottom wall of the air outlet duct 11 is the air outlet bottom wall 32, and the front edge of the air outlet bottom wall 32 is provided with an upwardly protruding first water-blocking rib 33. By forming the upwardly protruding first water-blocking rib 33 on the front edge of the air outlet bottom wall 32, when condensate drips onto the air outlet bottom wall 32, the first water-blocking rib 33 can contain the condensate, so that the condensate collects in the air outlet bottom wall 32, preventing the condensate from flowing outward and dripping onto the ground.

[0162] According to some embodiments of the present invention, with reference to Figures 25-30 The air guide plate 51 is located above the air outlet bottom wall 32, and the bottom of the air guide plate 51 is spaced apart from the air outlet bottom wall 32 in the vertical direction to form an assembly gap 55. The air outlet bottom wall 32 is provided with a windproof protrusion 34, which is located behind the first water-blocking protrusion 33 and is opposite to and spaced apart from the first water-blocking protrusion 33. By creating an assembly gap 55 by spacing the bottom of the air guide plate 51 from the bottom of the air outlet wall 32 vertically, the air guide plate 51 can be separated from the air outlet wall 32 during opening and closing, avoiding friction between the air guide plate 51 and the air outlet wall 32 that could cause wear to the air guide plate 51. By providing a wind-blocking protrusion 34 on the air outlet wall 32, and by positioning the wind-blocking protrusion 34 opposite to and spaced apart from the first water-blocking rib 33, when the air guide plate 51 is closed, the wind-blocking protrusion 34 and the first water-blocking rib 33 work together to seal, preventing dust in the air from entering the air conditioner. Furthermore, since the wind-blocking protrusion 34 is closer to the air outlet channel 11 than the first water-blocking rib 33, the cold air in the air outlet channel 11 preferentially passes through the wind-blocking protrusion 34, causing condensation to preferentially form on the outer surface of the wind-blocking protrusion 34. This prevents condensation from forming on the outer side of the first water-blocking rib 33, thus preventing condensation from forming on the exterior surface of the unit.

[0163] For example, the air guide plate 51 is provided with multiple air dissipation holes 52. The air conditioner has a windless mode. When the air conditioner is in the windless mode, the air guide plate 51 is in the closed air outlet 12 state, and the side wall of the air guide plate 51 is in contact with the sealing strip 58. By making the side wall of the air guide plate 51 in contact with the sealing strip 58, the sealing effect between the air guide plate 51 and the sealing strip 58 can be more complete, avoiding air leakage between the side wall of the air guide plate 51 and the sealing strip 58, which would reduce the windless effect.

[0164] According to some embodiments of the present invention, with reference to Figures 25-30 An air outlet grille 57 is provided inside the air outlet duct 11. The air outlet grille 57 is located on the upper side of the wind deflector 34 and is connected to the wind deflector 34. By connecting the air outlet grille 57 to the wind deflector 34, the bottom of the air outlet grille 57 protrudes beyond the bottom water receiving groove 35, preventing the bottom of the air outlet grille 57 from being located inside the bottom water receiving groove 35 and coming into contact with the condensate in the bottom water receiving groove 35.

[0165] According to some embodiments of the present invention, with reference to Figures 25-30 Multiple air diffusers 52 are formed on the air guide plate 51, and the air diffusers 52 penetrate the air guide plate 51 along its thickness direction. By forming multiple air diffusers 52 on the air guide plate 51, and having the air diffusers 52 penetrate the air guide plate 51 along its thickness direction, when the air guide plate 51 is in the closed state, airflow can be blown out from the multiple air diffusers 52, achieving a windless effect and avoiding the discomfort caused by direct airflow.

[0166] When the air guide plate 51 is in the position of closing the air outlet 12, refer to Figures 25-30 The wind deflector 34 is located inside the air guide plate 51, and at least part of the assembly gap 55 is located between the wind deflector 34 and the first water-blocking rib 33. When the air conditioner is in the windless mode, the air guide plate 51 is in the closed air outlet 12 state, and the side wall of the air guide plate 51 is in contact with the sealing strip 58. By making the side wall of the air guide plate 51 in contact with the sealing strip 58, the sealing effect between the air guide plate 51 and the sealing strip 58 can be more sufficient, avoiding air leakage between the side wall of the air guide plate 51 and the sealing strip 58, which would reduce the windless effect. By making at least part of the assembly gap 55 located between the wind deflector 34 and the first water-blocking rib 33, the assembly gap 55 can separate the wind deflector 34 and the first water-blocking rib 33, making the condensation on the outer surface of the wind deflector 34 more effective, and more effectively preventing condensation on the outer side of the first water-blocking rib 33.

[0167] According to some embodiments of the present invention, with reference to Figures 25-30 The bottom of the air guide plate 51 is provided with a bottom wind deflector 56, which is located behind the first water-blocking rib 33 and is opposite to and spaced apart from the first water-blocking rib 33. By providing a bottom baffle 56 at the bottom of the air guide plate 51, when the air conditioner is in the windless mode, the air guide plate 51 closes the air outlet 12. At this time, the bottom baffle 56 can block the airflow from flowing out of the assembly gap 55, avoiding air leakage in the assembly gap 55 and reducing the windless effect. By positioning the bottom baffle 56 behind the first water-blocking rib 33 and opposite to and spaced apart from the first water-blocking rib 33, interference between the bottom baffle 56 and the first water-blocking rib 33 can be avoided during the opening or closing of the air guide plate 51. Furthermore, since the bottom baffle 56 is closer to the air outlet channel 11 than the first water-blocking rib 33, the cold air in the air outlet channel 11 passes through the bottom baffle 56 first, causing condensation to form on the outer surface of the bottom baffle 56 first. This can prevent condensation from forming on the outer side of the first water-blocking rib 33 and prevent condensation from forming on the exterior surface of the unit.

[0168] Furthermore, when the air guide plate 51 is in the closed position of the air outlet 12, the bottom baffle 56 and the baffle boss 34 are arranged along the width direction of the air outlet 12. By arranging the bottom baffle 56 and the baffle boss 34 along the width direction of the air outlet 12, the assembly gap 55 can be blocked by the bottom baffle 56 and the baffle boss 34 in sequence, which can more effectively prevent air leakage in the assembly gap 55 and reduce the windless effect, thus improving the sealing performance. In addition, the bottom baffle 56 and the baffle boss 34 can jointly protect the first water-blocking rib 33, so that the cold air in the air outlet channel 11 passes through the bottom baffle 56 and the baffle boss 34 first, and the outer surface of the bottom baffle 56 and the baffle boss 34 will preferentially generate condensation water, which can more effectively prevent condensation water from generating on the outer side of the first water-blocking rib 33.
