[0021] This utility model provides a water tray assembly for an outdoor unit. To make the purpose, technical solution and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and examples.

[0022] In the description of this utility model, it should be understood that the terms "top" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation" and "connection" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figure 1-4As shown in the figure, this application embodiment proposes a water collection tray assembly for an outdoor unit, including a water collection tray 1, a water collection frame 2, a first fixing device 3, a second fixing device 4, a plurality of drain outlets 5 and drain nozzles 6. The water collection tray 1 is stacked on top of the water collection frame 2. The water collection frame 2 has an annular water groove on the side facing the water collection tray 1. The plurality of drain outlets 5 are arranged along the bottom edge of the water collection tray 1 and are all connected to the annular water groove. The drain nozzles 6 are arranged on the water collection frame 2 and are connected to the annular water groove. The first fixing device 3 is arranged on the outer periphery of the water collection tray 1 and the second fixing device 4 is arranged on the outer periphery of the water collection frame 2.

[0024] This utility model discloses a water collection tray assembly for an outdoor unit, comprising a water collection tray 1, a water collection frame 2, a first fixing device 3, a second fixing device 4, multiple drain outlets 5, and a drain nozzle 6. The water collection frame 2 has an annular water groove on the side facing the water collection tray 1. The water collection tray 1 is fixed inside the outdoor unit by the first fixing device 3, and the water collection frame 2 is fixed inside the outdoor unit by the second fixing device 4. The water collection tray 1 collects condensate generated by the heat exchanger and flows through the multiple drain outlets 5 into the annular water groove of the water collection frame 2. The drain nozzle 6 connects the annular water groove and a water pipe to discharge the condensate. This water collection tray assembly for an outdoor unit, disclosed in this application, collects and distributes condensate sequentially through the water collection tray 1 and the water collection frame 2, and discharges it centrally through the drain nozzle 6. This slows down the drainage rate, avoids air resistance caused by direct water flow impacting the drain nozzle 6, and simplifies the drainage pipeline, reducing the difficulty of disassembling and assembling the water collection tray assembly.

[0025] The water receiving frame 2 includes two L-shaped water receiving frames 21 and a water collecting hopper 22. Each L-shaped water receiving frame 21 has an L-shaped flow channel 23 on the side facing the water collecting pan 1. The water collecting hopper 22 has a locking groove 24 on both sides. One end of the two L-shaped water receiving frames 21 is respectively locked onto the two locking grooves 24. The drain nozzle 6 is located at the bottom of the water collecting hopper 22. The two L-shaped flow channels 23 and the water collecting hopper 22 are connected to form the annular water trough. The second fixing device 4 includes two fixing mechanisms, which are respectively correspondingly set on the two L-shaped water receiving frames 21, forming two water streams that flow to the water collecting hopper 22 respectively. This optimizes the water flow path, reduces the impact between water streams, and improves drainage efficiency. At the same time, the split structure facilitates subsequent maintenance.

[0026] Each of the L-shaped water receiving racks 21 includes a first water receiving groove 25, a second water receiving groove 26, and a connecting mechanism 27. The connecting mechanism 27 connects the first water receiving groove 25 and the second water receiving groove 26. The end of the second water receiving groove 26 away from the first water receiving groove 25 is engaged with any of the engaging grooves 24. The connecting mechanism 27 includes a bending groove 271, a water guiding slope 272, and a groove 273. The bending groove 271 is located on the end of the first water receiving groove 25 near the second water receiving groove 26, and the groove 273 is located on the second water receiving groove 26 facing the first water receiving groove 25. On one side of the water tank 25, the end of the bending groove 271 away from the first water receiving tank 25 is engaged with the groove 273. The water guiding slope 272 extends obliquely downward along the bottom edge of the bending groove 271. Condensate flows from the first water receiving tank 25 to the connecting mechanism 27, and the water is directed to the second water receiving tank 26 through the water guiding slope 272. This prevents some liquid from flowing out along the bottom of the bending groove 271. The bending groove 271 slows down the flow rate of the water to a certain extent, avoiding impact on the connection between the first water receiving tank 25 and the second water receiving tank 26.

[0027] Each of the aforementioned fixing mechanisms includes an L-shaped connector 41 and a screw hole 42. The L-shaped connector 41 is disposed on the periphery of any of the L-shaped water receiving brackets 21, and the screw hole 42 is disposed on the L-shaped connector 41. The L-shaped connector 41 is placed on the inner side of the outdoor unit to increase the contact area and is connected and fixed through the screw hole 42 to improve the stability of the fixing.

[0028] The water tray assembly also includes a reinforcing strip 7 and a protrusion 8. The reinforcing strip 7 is provided in both the first water receiving groove 25 and the second water receiving groove 26. The protrusion 8 is located on the top of the reinforcing strip 7. The water collecting tray 1 is provided with an insertion groove 9. The protrusion 8 is engaged with the insertion groove 9 to assist in the alignment of the water collecting tray 1 and the water receiving frame 2, ensuring that the drain outlet 5 is aligned with the annular water groove to prevent condensate from leaking out.

[0029] The water collection tray 1 includes a tray body 11, a protrusion 12, and two wire holes 13. The protrusion 12 is located in the middle of the tray body 11. Multiple drain outlets 5 are located around the protrusion 12 on the bottom of the tray body 11. The two wire holes 13 are located on the diagonal of the tray body 11 and on the surface of the tray body 11. The protrusion 12 allows condensable water to flow out towards the drain outlets 5 around the tray body 11, preventing water accumulation. The pipes inside the outdoor unit can pass through the wire holes 13, making the wiring inside the indoor unit neater.

[0030] The first fixing device 3 includes multiple mounting parts, which are respectively supported on the bottom edge of the water collection tray 1. Each mounting part is provided with a mounting hole. The bottom of the water collection tray 1 is provided with a connection hole 31 corresponding to the mounting hole. The mounting parts are fixed to the inner side of the outdoor unit. The water collection tray 1 is initially fixed by being mounted on multiple mounting parts. Then, the water collection tray 1 and the outdoor unit are further fixed by screws passing through the corresponding connection hole 31 and mounting hole.

[0031] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
