Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a drainage system and an air conditioner. Background Technology

[0002] In existing air conditioner designs, the drainage system is of paramount importance. Currently, in the market, floor-standing air conditioners create a temperature difference when hot and cold air meet during normal operation. When this temperature difference reaches the dew point of water vapor, condensation occurs, causing condensate to leak from or be blown out of the air conditioner. If this condensate cannot be drained effectively and promptly, it will drip or flow along the outer wall of the air conditioner onto the floor, corroding the user's flooring and potentially leading to quality complaints.

[0003] Conventional drainage systems are designed to collect and drain condensate from the evaporator heat exchange tubes and the walls on both sides of the air outlet. Some of these systems are poorly designed, and the condensate from the air outlet area cannot be effectively collected and drained. This results in a large amount of condensate inside the air conditioner not being able to drain, which can lead to water entering electrical components and causing electrical safety hazards. Summary of the Invention

[0004] The main objective of this invention is to provide a drainage system and an air conditioner that can effectively collect condensate generated in various parts of the air conditioner, thereby improving the safety of the air conditioner.

[0014] Furthermore, the third water receiving area is located below the second water receiving area and is projected vertically. The projection area of ​​the second water receiving area near the air outlet completely overlaps with the projection area of ​​the third water receiving area near the second water receiving area. The projection area of ​​the third water receiving area near the air outlet is located outside the second water receiving area.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] See also Figures 1 to 6As shown, according to an embodiment of the present invention, the drainage system includes a heat exchange assembly, an air outlet frame component, and a water collection tray component. The heat exchange assembly includes a bracket 26 and an indoor heat exchanger 21. The top surface of the bracket 26 is provided with a drainage groove 29 that guides the water to the indoor heat exchanger 21. The air outlet frame component includes an air outlet frame 20. The air outlet frame 20 is provided with a drainage structure 27 for diverting condensate on the air outlet frame 20. The water collection tray component includes an upper water collection tray 22 and a lower water collection tray 24. The upper water collection tray 22 is located below the indoor heat exchanger 21 and receives condensate flowing down from the indoor heat exchanger 21. The lower water collection tray 24 is located below the air outlet frame 20 and includes a second water collection area 2 and a third water collection area 3. The second water collection area 2 is configured to receive condensate generated in the inner area of ​​the air outlet, and the third water collection area 3 is configured to receive condensate generated in the air outlet area.

[0034] The drainage system features a drainage trough 29 on the top surface of the heat exchange component support 26, a flow-guiding structure 27 on the air outlet frame 20, an upper water collection tray 22 below the indoor heat exchanger 21, and a lower water collection tray 24 below the air outlet frame 20. The structure of the lower water collection tray 24 has been optimized so that it can collect condensate from both the inner and outer areas of the air outlet. This effectively collects and discharges the condensate generated by the air conditioner, improves the support strength of the water collection tray, and ensures the system's drainage function and the stability of the unit. This makes it less prone to water leakage in the air conditioner. The drainage system has a reasonable layout and good drainage effect.

[0035] In one embodiment, the lower water receiving tray 24 further includes a first water receiving area 1, which includes a drain outlet 15. The condensate from the upper water receiving tray 22, the second water receiving area 2, and the third water receiving area 3 is discharged into the first water receiving area 1 and discharged from the drain outlet. The second water receiving area 2 is configured to receive the condensate generated in the inner area of ​​the air outlet and discharge the collected condensate into the first water receiving area 1. The third water receiving area 3 is located on the air outlet side of the second water receiving area 2 and is configured to receive the condensate generated in the air outlet and discharge the collected condensate into the first water receiving area 1.

[0036] The lower water collection tray 24 includes a first water collection area 1, a second water collection area 2, and a third water collection area 3. The second water collection area 2 is used to collect condensate from the inside of the air outlet and the left and right sides of the air outlet. The third water collection area 3 is used to collect condensate generated in the air outlet area. The condensate generated in the air outlet area refers to the condensate generated in the air outlet area, including the inside and outside of the air outlet and the edge area of ​​the air outlet. This effectively collects the condensate generated in the left and right sides of the air outlet and the air outlet area, making the collection of condensate more comprehensive. This avoids the problem of a large amount of condensate accumulating inside the air conditioner and causing condensate to enter electrical components, thus preventing electrical safety hazards and improving the safety of the air conditioner.

[0037] In one embodiment, an inclined groove 28 is provided on the air outlet frame 20, and a diversion structure 27 is provided on the side of the air outlet frame 20. The end of the diversion structure 27 is provided corresponding to the beginning of the inclined groove 28. The end of the inclined groove 28 faces the second water receiving area 2. The condensate generated by the air outlet frame 20 can fall into the second water receiving area 2 through the diversion structure 27 and the inclined groove 28.

[0038] In this embodiment, the inclined groove 28 is disposed above the second water receiving area 2 and forms a connection with the flow guiding structure 27 on the air outlet frame 20. The flow guiding structure 27 can guide and collect the condensate on the air outlet frame 20, so that the condensate on the air outlet frame 20 can flow quickly along the flow guiding structure 27 along a preset trajectory to the inclined groove 28, and flow into the second water receiving area 2 for collection under the guiding action of the inclined groove 28, thereby improving the collection efficiency of condensate.

[0039] In one embodiment, the flow diversion structure 27 includes a flow diversion plate disposed at the bottom of the air outlet frame 20. The flow diversion plate is disposed on the periphery of the air outlet frame 20 and is inclined toward the inclined groove 28.

[0040] In this embodiment, the guide plate can be designed as a spiral plate structure, with the end of the spiral plate docking with the inclined groove 28, so that the condensate guided along the spiral plate can flow into the inclined groove 28 at the end of the spiral plate and be discharged into the second water receiving area 2 along the inclined groove 28.

[0041] In one embodiment, the drainage structure 27 includes a drainage groove disposed on the side of the air outlet frame 20 and extending obliquely in a downward direction, the end of the drainage groove being connected to the oblique groove 28.

[0042] In this embodiment, since the side of the air outlet frame 20 is provided with an obliquely extending drainage groove, when the condensate flows along the surface of the air outlet frame 20 under the action of gravity, it will flow into the drainage groove after reaching the location of the drainage groove, and after being gathered under the drainage action of the drainage groove, it will be quickly guided into the oblique groove 28 along the extension direction of the drainage groove, and then quickly discharged into the second water receiving area 2.

[0043] In one embodiment, the drainage system further includes an air duct 25 and an air inlet panel. The indoor heat exchanger 21 is fixed on the bracket 26, the air outlet frame 20 is fixed on the air duct 25, and the lower water receiving tray 24 is fixed through the air duct 25 and the air inlet panel. The air duct 25 is installed on the connecting seat 12 of the lower water receiving tray 24 and is fixedly connected to the connecting seat 12 through the connector 13, and is supported and positioned by the connecting seat 12.

[0044] In this embodiment, a drainage groove is designed on the top surface of the bracket 26 of the indoor heat exchanger 21. When the air conditioner is turned on, the heat exchange components exchange hot and cold air and generate condensate. Under the action of gravity, the condensate generated on the top surface of the bracket 26 of the indoor heat exchanger 21 gathers into the drainage groove 29 and flows from the drainage groove 29 to the indoor heat exchanger 21. The condensate generated by the indoor heat exchanger 21 itself and the condensate collected in the drainage groove 29 on the top surface of the bracket 26 flow out of the indoor heat exchanger 21 together and then flow into the upper water receiving tray 22 fixed to the indoor heat exchanger 21. The condensate is discharged to the lower water receiving tray 24 through the drain port of the upper water receiving tray 22. The air outlet frame 20 is assembled and fixed to the volute by buckles and screws. The side of the air outlet frame 20 is designed with a drainage groove. When condensate is generated on the side of the air outlet frame 20, the condensate falls into the lower water receiving tray 24 through the inclined groove 28 and is finally discharged through the drain port 15.

[0045] In one embodiment, the vertical projections of the upper water receiving tray 22 and the air outlet frame 20 fall into the vertical projection area of ​​the lower water receiving tray 24.

[0046] This structural design allows condensate from the upper water tray 22 and the air outlet frame 20 to fall smoothly into the water collection area of ​​the lower water tray 24, thereby effectively preventing condensate from falling into the lower water tray 24 and affecting the surrounding environment.

[0047] The second water inlet area 2 and the third water inlet area 3 are staggered to form a stepped structure. The first water inlet area 1 is located on the side of the second water inlet area 2 away from the third water inlet area 3, and together with the second water inlet area 2 and the third water inlet area 3, they form the drive installation area.

[0048] The lower water tray 24 utilizes the stepped structure formed by the second water receiving area 2 and the third water receiving area 3 to cooperate with the first water receiving area 1, forming the actuator installation area 19. This area can be used to install the actuator that opens or closes the air outlet panel. This allows for a more reasonable limitation of the structure of the lower water tray 24, fully leveraging its structural advantages and making better use of space. It facilitates the installation of the actuator while preventing condensate from falling from the air outlet into electrical components. It also makes the installation position of the actuator easier to adjust the position of the air outlet panel, resulting in a more optimized overall structural layout.

[0049] The lower drip tray 24 is divided into three drip areas, which can be used to collect condensate generated by different components of the air conditioner, improving the comprehensiveness and efficiency of condensate collection, effectively avoiding condensate leakage, and providing effective protection for the internal components of the air conditioner.

[0050] In one embodiment, the third water collection area includes an annular area that can better match the shape of the air outlet area, thereby reliably collecting condensate generated on the front of the air outlet.

[0051] In one embodiment, the gap between the second water inlet area 2 and the third water inlet area 3 forms a drive arm movement slot, which is configured to allow the drive arm to extend from the driver mounting area and provide movement space for the drive arm.

[0052] In this embodiment, the second water receiving area 2 and the third water receiving area 3 are staggered vertically. The staggered structure can form a drive arm movement groove between the second water receiving area 2 and the third water receiving area 3, which facilitates the installation of the driver and provides movement space for the drive arm, avoiding interference with the movement of the drive arm. The drive arm can extend through the drive arm movement groove and connect with the air outlet panel. The state of the air outlet panel can be adjusted by the movement within the drive arm movement groove, thereby adjusting the air outlet status of the air conditioner.

[0053] In one embodiment, the width of the drive arm movable groove is configured to match the width of the drive arm. When the drive arm moves within the drive arm movable groove, the drive arm movable groove has only a width suitable for the movement of the drive arm. Therefore, the gap formed by the vertical misalignment between the second water receiving area 2 and the third water receiving area 3 is small, effectively preventing condensate from outside the driver mounting area from entering the driver mounting area through the drive arm movable groove, thus providing effective protection for the driver located in the driver mounting area.

[0054] The drive box 23 located at the bottom of the air outlet frame 20 is assembled with the lower water receiving tray 24. The water receiving area of ​​the lower water receiving tray 24 is designed as an annular water receiving groove based on the water receiving area of ​​the drive box 23. It is located on the lower side of the water receiving area of ​​the lower water receiving tray 24, forming an upper and lower staggered structure. The annular water receiving groove runs through both sides. This water receiving groove is mainly used to collect condensate generated in the air outlet area. The bottom surface is inclined. The condensate flows into the interior of the lower water receiving tray 24 through the junction of the two sides and finally flows out from the drain outlet 15.

[0055] In one embodiment, the second water receiving area 2 includes multiple installation steps, the height of which decreases sequentially from the middle to both sides.

[0056] In this embodiment, the second water receiving area 2 adopts a stepped structure, which can better adapt to the structure of components such as drive box 23 installed in the drive mounting area 19, and make it easier to install and fix the components in the drive mounting area 19.

[0057] The height of the steps decreases gradually from the middle to both sides, which makes it easier for condensate to flow along the steps to both sides and then be discharged into the first water receiving area 1.

[0058] In one embodiment, the lower water receiving tray 24 includes a drive box 23, a third water receiving area 3 is formed by the cover of the drive box 23, and a drive mounting area is used to mount the part of the drive box 23 excluding the cover. The drive box 23 is configured to accommodate the drive.

[0059] In this embodiment, the third water receiving area 3 exists independently of the first water receiving area 1 and the second water receiving area 2. This allows the first water receiving area 1 and the second water receiving area 2, which are the main body of the upper water receiving tray 22, to exist as one part, while the third water receiving area 3, which is a supplementary part of the upper water receiving tray 22, exists as another part. This allows the third water receiving area 3 to be formed by the cover of the drive box 23, eliminating the need for a separate third water receiving area 3. This avoids interference between the third water receiving area 3 and the drive box 23, and fully utilizes the structural features of the drive box 23. This allows the cover function of the drive box 23 to be fully utilized, saving parts and making the function of the drive box more diversified. It enables the collection of condensate at the air outlet. In addition, the cover structure of the drive box 23 can be used to more effectively block condensate, preventing condensate at the air outlet from falling into the electrical appliances and causing damage.

[0060] In one embodiment, the third water receiving area 3 is located below the second water receiving area 2 and is projected vertically. The projection area of ​​the second water receiving area 2 near the air outlet completely overlaps with the projection area of ​​the third water receiving area 3 near the second water receiving area 2. The projection area of ​​the third water receiving area 3 near the air outlet is located outside the second water receiving area 2.

[0061] In this embodiment, the third water receiving area 3 is positioned below the second water receiving area 2, and the projections of the two at their adjacent positions overlap. This allows for more reliable collection of condensate generated at the air outlet and surrounding areas, effectively preventing condensate from falling into areas outside the second and third water receiving areas 2 and 3. Since the projection area of ​​the second water receiving area 2 near the air outlet completely overlaps with the projection area of ​​the third water receiving area 3 near the second water receiving area 2, when condensate falls, it either falls into the second water receiving area 2 or the third water receiving area 3. This avoids the problem of condensate leakage caused by the gap between the second and third water receiving areas 2 and 3 on their projection surfaces, further improving the effectiveness of condensate collection and preventing condensate leakage.

[0062] Within the projection plane perpendicular to the vertical axis, the edge line of the second water receiving area 2 near the air outlet and the edge line of the third water receiving area 3 away from the air outlet can be completely identical and overlap. This minimizes the overlap area between the second and third water receiving areas 2 and 3, maximizing the catch-up area and providing a larger catch-up area for condensate. This effectively prevents condensate from the air outlet from splashing onto areas outside the second and third water receiving areas 2 and 3. Furthermore, since the second water receiving area 2 is located above the third water receiving area 3, the overlap area between the third and second water receiving areas 2 is smaller. This also prevents the third water receiving area 3 from occupying too much volume in the drop area between the second and third water receiving areas 2 and 3, allowing this volume to be more fully utilized for installing other components, such as the drive box 23.

[0063] In one embodiment, the edge line of the second water receiving area 2 near the air outlet can be located outside the edge line of the third water receiving area 3 away from the air outlet, that is, on the side closer to the air outlet, so that there is an overlapping area between the second water receiving area 2 and the third water receiving area 3, rather than the edge lines coinciding. By increasing the overlapping area of ​​the projections of the second water receiving area 2 and the third water receiving area 3, the phenomenon of condensate spillage can be more effectively avoided, and the reliability of condensate collection can be improved.

[0064] In one embodiment, the second water receiving area 2 includes a first outer baffle 4 near the air outlet, and the third water receiving area 3 includes a first inner baffle 5 away from the air outlet, with the projection areas of the first outer baffle 4 and the first inner baffle 5 overlapping.

[0065] In this embodiment, the first outer baffle 4 is used to prevent condensate from spilling from the outer edge of the second water receiving area 2 near the air outlet, and the first inner baffle 5 is used to prevent condensate from spilling from the inner edge of the third water receiving area 3 away from the air outlet, thereby forming a blocking effect on the condensate and ensuring that the condensate falls more thoroughly into the lower water receiving tray 24.

[0066] In one embodiment, the second water receiving area 2 and the third water receiving area 3 are vertically offset, and the bottom of the second water receiving area 2 is higher than the top of the third water receiving area 3.

[0067] In this embodiment, the second water receiving area 2 and the third water receiving area 3 are vertically offset, which can form a misaligned space between them. This misaligned space can be used to create space for installing other components, making fuller use of the space.

[0068] In one embodiment, the lower water receiving tray 24 includes a first tray body 6 and a second tray body 7, a first water receiving area 1 and a second water receiving area 2 located on the first tray body 6, a third water receiving area 3 located on the second tray body 7, and the second tray body 7 is detachably connected to the first tray body 6.

[0069] In this embodiment, the lower water receiving tray 24 is divided into two trays, with the first water receiving area 1 and the second water receiving area 2 located on the first tray 6, and the third water receiving area 3 located separately on the second tray 7. The second tray 7 and the first tray 6 are detachably connected. This is because the third water receiving area 3 is a ring structure and together with the first water receiving area 1 and the second water receiving area 2, it forms the driver installation area 19. If the third water receiving area 3 were to form an integral structure with the first water receiving area 1 and the second water receiving area 2, the installation and disassembly of the components installed in the driver installation area 19 would become very inconvenient and the operation would be more complicated. By setting the first tray 6 and the second tray 7 as detachable structures, when installing components, the second tray 7 can be removed from the first tray 6 first, and then the components can be installed. After the components are installed, the second tray 7 can be installed on the first tray 6, thereby avoiding the second tray 7 from obstructing the installation of components and improving the convenience of component installation in the driver installation area 19.

[0070] In one embodiment, the bottom surface of the second water receiving area 2 is higher than the bottom surface of the first water receiving area 1, a step is formed between the first water receiving area 1 and the second water receiving area 2, the bottom surface of the third water receiving area 3 is higher than the bottom surface of the first water receiving area 1, the second plate 7 is inserted into the vertical surface of the step, and a water conveying channel is formed at the insertion position, and the third water receiving area 3 conveys condensate to the first water receiving area 1 through the water conveying channel.

[0071] In this embodiment, since both the first water receiving area 1 and the second water receiving area 2 are formed on the first plate 6 and have different heights, a height difference is formed between them. Therefore, a step is formed between the first water receiving area 1 and the second water receiving area 2 due to this height difference. The vertical surface of the step connects the bottom surface of the first water receiving area 1 and the bottom surface of the second water receiving area 2, meaning the vertical surface of the step is above the bottom surface of the first water receiving area. Therefore, by inserting the second plate 7 into the vertical surface of this step, the height of the third water receiving area 3 is higher than the height of the first water receiving area 1, facilitating the drainage of condensate from the third water receiving area 3 into the first water receiving area 1. Because the second plate 7 and the first plate 6 are connected by an insertion joint, the assembly structure of the second plate 7 and the first plate 6 is simpler, and assembly and disassembly are more convenient and faster, enabling rapid assembly and disassembly of the second plate 7 and the first plate 6.

[0072] In one embodiment, in a top view, the second disc 7 is U-shaped, with both ends of the second disc 7 inserted into the vertical surface, and the second water receiving area 2 is located between the two side walls of the U-shaped structure of the second disc 7.

[0073] In this embodiment, the second disc 7 is U-shaped, thus forming two protrusions at both ends. The second disc 7 can be inserted into the vertical surface through the two protrusions, making the assembly structure between the second disc 7 and the first disc 6 more balanced. In addition, it also allows the condensate in the third water receiving area 3 to drain from both sides simultaneously through the two protrusions into the first water receiving area 1, improving the drainage efficiency of the condensate in the third water receiving area 3.

[0074] By placing the second water receiving area 2 between the two side walls of the U-shaped structure of the second plate 7, interference between the matching structure of the second plate 7 and the first plate 6 and the flow guiding structure of the second water receiving area 2 and the first water receiving area 1 can be avoided. This ensures that the flow guiding structures of the second water receiving area 2 and the first water receiving area 1, as well as the flow guiding structures of the third water receiving area 3 and the first water receiving area 1, are staggered and do not affect each other, resulting in smoother drainage of condensate.

[0075] In one embodiment, at the insertion position, the first disc 6 and the second disc 7 are fitted with a clearance, which can further reduce the assembly difficulty between the second disc 7 and the first disc 6 and improve assembly efficiency. To prevent condensate from leaking from the junction of the first water inlet area 1 and the third water inlet area 3, there is a height difference between the third water inlet area 3 and the first water inlet area 1 at the insertion position, and the height of the first water inlet area 1 at the junction with the third water inlet area 3 is higher than its height at the drain outlet 15.

[0076] In one embodiment, the first water receiving area 1 includes a first water guiding surface 8 and a second water guiding surface 9, the drain outlet 15 is located at the bottom of the first water guiding surface 8, the second water guiding surface 9 is located between the first water guiding surface 8 and the third water receiving area 3, and the inclination angle of the second water guiding surface 9 is greater than the inclination angle of the first water guiding surface 8.

[0077] In this embodiment, the tilt angle of the second water guide surface 9 is greater than that of the first water guide surface 8, which increases the height difference between the side of the second water guide surface 9 closest to the third water receiving area 3 and the side furthest from the third water receiving area 3. This allows the condensate flowing in from the third water receiving area 3 to be quickly guided from the second water guide surface 9 to the first water guide surface 8, and then discharged from the drain outlet 15 at the bottom of the first water guide surface 8. This can more effectively prevent condensate from leaking from the insertion position of the second plate 7 and the first plate 6.

[0078] In one embodiment, the bottom height of the second water receiving area 2 decreases from the middle to both sides, and the second water receiving area 2 is provided with drainage channels 11 on both sides near the first water receiving area 1.

[0079] In this embodiment, by varying the bottom height of the second water receiving area 2, condensate can be quickly discharged from the second water receiving area 2, and the drain trough 11 facilitates the discharge of condensate from the second water receiving area 2 to the first water receiving area 1. Furthermore, the presence of the drain trough 11 also guides the flow of condensate, ensuring that it is discharged along a predetermined path and at a predetermined location, thus optimizing the condensate discharge location.

[0080] In one embodiment, reinforcing ribs 10 are provided on both the outer side of the second water receiving area 2 near the air outlet and the inner side away from the air outlet. The height of the reinforcing ribs 10 is higher than the bottom height of the second water receiving area 2. A flow guiding channel is formed between the reinforcing ribs 10 near the air outlet and the reinforcing ribs 10 away from the air outlet, and a drain trough 11 is formed at the end of the flow guiding channel.

[0081] In this embodiment, by providing reinforcing ribs 10 on the inner and outer sides of the second water receiving area 2, the flow of condensate can be guided and blocked, preventing spillage. Simultaneously, the condensate can flow along a predetermined path, allowing it to be discharged from the drain trough 11. Furthermore, the reinforcing ribs 10 enhance the structural strength of the second water receiving area 2, providing a solid foundation for the installation and fixation of the air duct 25. In this embodiment, the reinforcing ribs 10 can also serve as the first outer retaining edge 4 of the second water receiving area 2.

[0082] In one embodiment, a connecting seat 12 is provided in the middle of the second water receiving area 2. The connecting seat 12 is fixedly connected to the first water receiving area 1 by a reinforcing rib 10, and a connecting member 13 is provided on the connecting seat 12.

[0083] In this embodiment, by setting the connecting seat 12, an installation foundation can be provided for the installation of the air duct 25. By setting the connector 13 on the connecting seat 12, the air duct 25 can be easily installed and fixed on the connecting seat 12. The connecting seat 12 is used to position the air duct 25, preventing the air duct 25 from shifting during use and ensuring the stability and reliability of the installation structure of the air duct 25.

[0084] In one embodiment, a water collection structure 14 is provided on the first water receiving area 1, and the water collection structure 14 is provided corresponding to the drain outlet 15. The water collection structure 14 is configured to receive the condensate generated by the indoor heat exchanger and guide it to the drain outlet 15.

[0085] In this embodiment, the water collection structure 14 has two functions: one is to collect the condensate generated by the indoor heat exchanger and quickly discharge it; the other is to collect the condensate in the first water receiving area 1 and then discharge it from the drain outlet 15. Therefore, the water collection structure 14 has two parts: one part is located on the upper side, which cooperates with the indoor heat exchanger 21 to collect the condensate generated by the indoor heat exchanger 21 and guides the flow of the condensate so that the condensate generated by the indoor heat exchanger 21 can collect towards the drain outlet 15; the other part is located on the lower side, which cooperates with the bottom surface of the first water receiving area 1 so that the condensate in the first water receiving area 1 can collect towards the drain outlet 15 along the guide of this part.

[0086] In one embodiment, the water collection structure 14 includes an upward-facing collection trough 16 and a downward-facing flow channel 17. The flow channel 17 cooperates with the bottom surface of the first water receiving area 1 to form a flow channel. The bottom of the collection trough 16 forms a water collection port. The flow channel and the water collection port are connected to the drain outlet 15.

[0087] In this embodiment, the guide surface of the collecting trough 16 is an inclined surface, and the drain outlet 15 is located at the bottom of the collecting trough 16. The collecting trough 16 is directly opposite the drain channel of the upper water receiving pan 22 of the indoor heat exchanger 21, so that the condensate in the upper water receiving pan 22 can fall into the collecting trough 16 and enter the drain outlet 15 from the bottom of the collecting trough 16 for discharge. Along the direction away from the drain outlet 15, the bottom height of the collecting trough 16 increases, which makes it easier for the condensate to collect. The flow channel 17 is a quarter-circular arc channel and is located at the bottom of the water collection structure 14, used to collect the condensate located in the first water receiving area 1. The flow channel 17 has a conical structure, and along the direction away from the drain outlet 15, the cross-section of the flow channel 17 increases, which makes it easier for the condensate to collect.

[0088] In one embodiment, a conical groove is also provided at the bottom of the collection trough 16, with the central axis of the conical groove aligned with the central axis of the drain outlet 15, which facilitates the collection of condensate.

[0089] In one embodiment, a plurality of positioning elements 18 are provided on the first water receiving area 1, the positioning elements 18 surround the positioning area, the water collecting structure 14 is located in the positioning area, and an interference fit is formed between the water receiving area 14 and the positioning elements 18.

[0090] In this embodiment, the water collection structure 14 is detachably disposed in the first water receiving area 1, so that the water collection structure 14 and the first water receiving area 1 are separate structures, which can be processed separately and then combined together, thereby reducing the processing difficulty and processing cost of each, and making it easier to process the required structure.

[0091] The water collection structure 14 and the positioning part 18 form an interference fit, and the positioning part 18 can be used to install and fix the water collection structure 14, so that the water collection structure 14 and the positioning part 18 form a plug-in fixation. The overall structure is simpler, easier to operate, and more convenient to install and replace the water collection structure 14.

[0092] In one embodiment, the water collection structure 14 is made of foam, which can reduce the noise of condensate flow and reduce the weight of the lower water collection tray 24, thus achieving the lightweighting of the lower water collection tray 24.

[0093] In one embodiment, the lower water receiving tray 24 is made of a plastic material that is resistant to high temperatures, has good stability, and high strength.

[0094] In one embodiment, the second water receiving area is divided into three water collection tanks, which form a U-shaped structure. The bottom of the tanks is inclined towards the first water receiving area 1 to facilitate the collection of condensate water generated by the hot and cold air blown out of the air duct 25 and the condensate water generated on the side wall of the air outlet, which flows to the first water receiving area 1.

[0095] In one embodiment, a U-shaped pipe channel is provided on one side of the first plate 6 to allow the connecting pipes on the indoor heat exchanger 21 to pass through. Baffle plates are provided on the two opposite sidewalls of the U-shaped pipe channel, extending toward each other to form an S-shaped baffle structure. This effectively prevents the connecting pipes located in the U-shaped pipe channel from coming out of the U-shaped pipe channel, thereby improving the stability and reliability of the connecting pipe installation structure.

[0096] In one embodiment, the front of the lower water receiving tray 24 is provided with four positioning pin holes and screw through holes for assembly and fixing with parts.

[0097] In this embodiment, the first water receiving area 1 is mainly used to receive the condensate generated by the indoor heat exchanger 21, the second water receiving area 2 is mainly used to collect the condensate generated by the hot and cold air blown out of the air duct 25 and the condensate generated on the side wall of the air outlet, and the third water receiving area 3 is mainly used to collect the condensate generated in the air outlet area.

[0098] In the air conditioner's cooling mode, condensation occurs on the indoor heat exchanger and duct walls due to cold radiation. This condensation flows down from the drain groove 29 on the top surface of the bracket 26 of the indoor heat exchanger 21, and together with the condensation generated by the indoor heat exchanger 21 itself, flows from the drain outlet of the upper water collection tray 22 below the indoor heat exchanger 21 to the lower water collection tray 24. Condensation on the side of the air outlet frame 20 flows directly into the lower water collection tray 24 through the guide groove. Condensation generated in the air outlet area is collected by the annular water collection groove around the drive box, flows through the confluence, and then flows onto the first water collection area 1 of the lower water collection tray 24. It then flows along the inclined surface of the collection groove 16 to the drain outlet 15, and finally is discharged through the drain pipe. The drainage system of this embodiment of the invention features a simple structure, a wide water collection range, and convenient assembly and disassembly.
