Description

Technical Field

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

[0002] In existing centrifugal fan system technology for air conditioners, the condensate tray of a cabinet air conditioner serves to collect condensate and protect electrical components. The condensate tray typically collects condensate and drains it through a drain hole. The condensate tray structure includes a main body, front and rear condensate trays, and a drain outlet. The condensate trays primarily collect condensate from the left and right sides of the air outlet and from the evaporator, ultimately draining through the drain outlet.

[0003] The aforementioned drip tray is only used to collect and drain condensate generated on the evaporator heat exchange tubes and the left and right side walls of the air outlet. Its assembly is complicated, and it cannot effectively collect and drain condensate generated in the air outlet area. As a result, a large amount of condensate inside the air conditioner cannot be drained, which can lead to water entering electrical components and causing potential electrical safety hazards. In addition, the structure of the drip tray can also affect the installation of other components, resulting in the space occupied by the drip tray structure not being fully utilized. Summary of the Invention

[0004] The main objective of this invention is to provide a water collection tray and an air conditioner that can effectively collect condensate generated on the front of the air outlet, improve the safety of the air conditioner, and make full use of the space formed by the water collection tray structure to improve space utilization.

The projection area of ​​the third water receiving area near the air outlet is located outside the second water receiving area.

[0015] Furthermore, the second water receiving area includes a first outer baffle near the air outlet, and the third water receiving area includes a first inner baffle away from the air outlet, with the projection areas of the first outer baffle and the first inner baffle overlapping.

The second tray body is detachably connected to the first tray body.

[0018] Furthermore, the bottom surface of the second water receiving area is higher than the bottom surface of the first water receiving area, forming a step between the first and second water receiving areas. The bottom surface of the third water receiving area is higher than the bottom surface of the first water receiving area. The second plate is inserted into the vertical surface of the step, forming a water conveying channel at the insertion position. The third water receiving area conveys condensate to the first water receiving area through the water conveying channel.

[0019] Furthermore, in a top-down view, the second disc is U-shaped, with both ends of the second disc inserted into the vertical surface, and the second water-receiving area is located between the two side walls of the U-shaped structure of the second disc.

[0020] Furthermore, at the insertion position, the first disc body and the second disc body are fitted with a clearance.

[0021] Furthermore, the first water receiving area includes a first water guiding surface and a second water guiding surface, the drain outlet is located at the bottom of the first water guiding surface, the second water guiding surface is located between the first water guiding surface and the third water receiving area, and the inclination angle of the second water guiding surface is greater than the inclination angle of the first water guiding surface.

[0022] Furthermore, the bottom height of the second water receiving area decreases from the middle to both sides, and drainage channels are provided on both sides of the second water receiving area near the first water receiving area.

[0023] Furthermore, the second water receiving area is provided with reinforcing ribs on both the outer side near the air outlet and the inner side away from the air outlet. The height of the reinforcing ribs is higher than the bottom surface of the second water receiving area. A flow guiding channel is formed between the reinforcing ribs near the air outlet and the reinforcing ribs away from the air outlet, and a drainage trough is formed at the end of the flow guiding channel.

[0024] Furthermore, a connecting seat is provided in the middle of the second water receiving area. The connecting seat is fixedly connected to the first water receiving area through reinforcing ribs, and a connecting component is provided on the connecting seat.

[0025] Furthermore, a water collection structure is provided on the first water receiving area, and the water collection structure is set corresponding to the drain outlet. The water collection structure is constructed to receive the condensate generated by the indoor heat exchanger and guide it to the drain outlet.

[0026] Furthermore, the water collection structure includes an upward-opening collection trough and a flow passage located on the lower side. The flow passage cooperates with the bottom surface of the first water receiving area to form a flow passage. The bottom of the collection trough forms a water collection port. The flow passage and the water collection port are connected to the drain outlet.

[0027] Furthermore, multiple positioning components are installed on the first water receiving area, forming a positioning area. The water collection structure is located within the positioning area and forms an interference fit with the positioning components.

[0028] Furthermore, the water collection structure is made of foam.

[0029] According to another aspect of the present invention, an air conditioner is provided, including a water receiving tray, which is the water receiving tray described above.

[0030] Furthermore, the air conditioner also includes an indoor heat exchanger and an air outlet frame.

The drip tray includes a first drip area, a second drip area, and a third drip area. The second drip area collects condensate from the inside and sides of the air outlet, while the third drip area collects condensate generated at the air outlet. This effectively collects condensate from the sides and front of the air outlet, ensuring more comprehensive condensate collection and preventing excessive condensate buildup inside the air conditioner from entering electrical components and causing electrical safety hazards. This improves the safety of the air conditioner. The drip tray utilizes the stepped structure formed by the second and third drip areas, in conjunction with the first drip area, to create a drive unit installation area. This area can be used to install the drive unit that opens or closes the air outlet panel. This allows for a more rational limitation of the drip tray structure, fully utilizing its structural advantages and space. It facilitates drive unit installation while preventing condensate from falling from the air outlet into electrical components. It also makes the drive unit's installation position easier to adjust the air outlet panel, resulting in a more optimized overall structural layout. Attached Figure Description

[0039] 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.

[0040] See also Figures 1 to 4 As shown, according to an embodiment of the present invention, the water receiving tray includes: a first water receiving area 1 having a drain outlet 15; a second water receiving area 2 configured to receive condensate generated in the inner area of ​​the air outlet and discharge the collected condensate to the first water receiving area 1; and a third water receiving area 3 disposed on the air outlet side of the second water receiving area 2, configured to receive condensate generated in the air outlet and discharge the collected condensate to the first water receiving area 1. The second water receiving area 2 and the third water receiving area 3 are staggered to form a stepped structure. The first water receiving area 1 is disposed on the side of the second water receiving area 2 away from the third water receiving area 3, and together with the second water receiving area 2 and the third water receiving area 3, forms a drive installation area.

[0041] The drip tray includes a first drip area 1, a second drip area 2, and a third drip area 3. The second drip 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 drip 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.

[0042] The water tray 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 to form the driver installation area 19. This area can be used to install the driver that opens or closes the air outlet panel. This allows for a more reasonable limitation of the water tray structure, fully utilizing its structural advantages and making better use of space. It facilitates the installation of the driver while preventing condensate from falling from the air outlet into electrical components. It also makes the installation position of the driver easier to adjust the position of the air outlet panel, resulting in a more optimized overall structural layout.

[0043] The drip tray 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] In one embodiment, the water receiving tray 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.

[0052] 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 water receiving box, to exist as one part, while the third water receiving area 3, which is a supplementary part of the water receiving box, 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 also makes full use of the structural features of the drive box 23. This allows the cover function of the drive box 23 to be fully utilized. While saving parts, this makes the function of the drive box more diversified, enabling the collection of condensate at the air outlet. In addition, the cover structure of the drive box 23 can also be used to more effectively block condensate, preventing condensate at the air outlet from falling into the electrical appliances and causing damage.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 water receiving tray.

[0059] 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.

[0060] 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.

[0061] In one embodiment, the water receiving tray 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 are located on the first tray body 6, a third water receiving area 3 is located on the second tray body 7, and the second tray body 7 is detachably connected to the first tray body 6.

[0062] In this embodiment, the water receiving tray 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 has 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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 water receiving box 22 of the indoor heat exchanger 21, so that the condensate in the water receiving box 22 can fall into the collecting trough 16 and enter the drain outlet 15 from the bottom of the collecting trough 16 and be discharged. 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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 water tray, thus achieving a lightweight water tray.

[0086] In one embodiment, the drip tray is made of a high-temperature resistant, stable, and high-strength plastic material.

[0087] 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.

[0088] 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.

[0089] In one embodiment, the front of the water receiving tray is provided with four positioning pin holes and screw through holes for assembly and fixing with parts.

[0090] According to an embodiment of the present invention, the air conditioner includes a water receiving tray 24, which is the water receiving tray described above.

[0091] In one embodiment, the air conditioner further includes an indoor heat exchanger 21 and an air outlet frame 20. A first water receiving area 1 and a second water receiving area 2 are located below the air outlet frame 20. The first water receiving area 1 is located below the air outlet area of ​​the air outlet frame 20, and the second water receiving area 2 is located below the inner side area of ​​the air outlet of the air outlet frame 20. A water receiving box 22 is provided below the indoor heat exchanger 21, and a water receiving tray 24 is located below the water receiving box 22 and receives the condensate discharged from the water receiving box 22.

[0092] The air conditioner also includes an air duct 25, which is installed on the connecting seat 12 of the 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.

[0093] 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.

[0094] In the air conditioner's cooling mode, condensation occurs on the indoor heat exchanger and duct walls due to cold radiation. The condensation flows down the walls and into the drain outlet of the water collection box 22, eventually reaching the first water collection area 1. Condensation generated in the air vent area is collected in the third water collection area 3 and flows through the junction of the first tray 6 and the second tray 7, then into the first water collection area 1 of the water collection tray 24. Under its own gravity, the condensation flows along the inclined surface of the collection groove 16 to the drain outlet 15, and finally is discharged through the drain pipe. The water collection tray of this embodiment features a simple structure, a wide water collection range, and convenient assembly and disassembly.
