[0052] Shell assembly 101 includes chassis part 11, and the chassis part 11 is used to support and install heat exchanger assembly 40 and fan assembly 50.

[0053] Chassis part 11 is formed with water receiving groove 12, and the water receiving groove 12 is used to receive condensed water flowing from heat exchanger assembly 40.

[0054] The bottom wall of water receiving groove 12 is formed with drainage groove 17, and the drainage groove 17 extends from first water receiving area 13 to second water receiving area 15, for example, the drainage groove 17 includes inlet end 18 and outlet end 19, the inlet end 18 is located in the first water receiving area 13, and the outlet end 19 is located in the second water receiving area 15.

[0057] According to the air conditioner of the embodiments of the present application, the drainage groove 17 is arranged on the bottom wall of the water collecting groove 12, and the drainage groove 17 extends from the first water collecting area 13 to the second water collecting area 15. Water in the first water collecting area 13 can flow downward into the second water collecting area 15 under the action of gravity and the drainage effect of the drainage groove 17. Thus, under the drainage effect of the drainage groove 17, water in the first water collecting area 13 can easily flow downward into the second water collecting area 15, thereby reducing the risk of overflow of the first water collecting area 13 due to excessive water accumulation.

[0058] According to some embodiments of the present application, with reference to Figure 6 The depth of the drainage groove 17 is b, and b is in the range of 5mm to 16mm. For example, b can be 5mm, 7mm, 9mm, 12mm, 16mm, etc. By making the depth b of the drainage groove 17 not less than 5mm, the drainage groove 17 can sufficiently guide water in the first water collecting area 13 into the second water collecting area 15, so that water in the first water collecting area 13 can be more easily drained. By making the depth b of the drainage groove 17 not greater than 16mm, the structural strength of the bottom pan assembly can be avoided from being reduced due to the drainage groove 17 being too deep.

[0059] According to some embodiments of the present application, with reference to Figure 6 and Figure 10 The drainage groove 17 is a groove formed on the bottom wall of the water collecting groove 12. By making the drainage groove 17 a groove formed on the bottom wall of the water collecting groove 12, the structure of the drainage groove 17 can be simple and easy to manufacture.

[0060] According to some embodiments of the present application, with reference to Figure 10The drainage groove 17 comprises an introduction end 18 and an outlet end 19, the introduction end 18 is located at one end of the first water receiving area 13 close to the second water receiving area 15, and the outlet end 19 is located in the second water receiving area 15. By locating the introduction end 18 of the drainage groove 17 at one end of the first water receiving area 13 close to the second water receiving area 15 and locating the outlet end 19 in the second water receiving area 15, the drainage groove 17 can guide the water in the first water receiving area 13 to flow to the second water receiving area 15, avoiding the water in the first water receiving area 13 from overflowing due to excessive water.

[0061] According to some embodiments of the present application, referring to Figure 10 The drainage groove 17 comprises an introduction end 18 and an outlet end 19, the introduction end 18 is located at one end of the first water receiving area 13 close to the second water receiving area 15, and the outlet end 19 is located in the second water receiving area 15. By locating the introduction end 18 of the drainage groove 17 at one end of the first water receiving area 13 close to the second water receiving area 15 and locating the outlet end 19 in the second water receiving area 15, the drainage groove 17 can guide the water in the first water receiving area 13 to flow to the second water receiving area 15, avoiding the water in the first water receiving area 13 from overflowing due to excessive water.

[0062] According to some embodiments of the present application, referring to Figure 9 and Figure 11 The drainage groove 17 comprises an introduction end 18 and an outlet end 19, the introduction end 18 is located at one end of the first water receiving area 13 close to the second water receiving area 15, and the outlet end 19 is located in the second water receiving area 15. By locating the introduction end 18 of the drainage groove 17 at one end of the first water receiving area 13 close to the second water receiving area 15 and locating the outlet end 19 in the second water receiving area 15, the drainage groove 17 can guide the water in the first water receiving area 13 to flow to the second water receiving area 15, avoiding the water in the first water receiving area 13 from overflowing due to excessive water.

[0063] According to some embodiments of the present application, referring to Figure 10The bottom wall of the first water receiving area 13 is provided with a protruding structure 20, and the protruding structure 20 defines a drainage port 28 located at the edge of the drainage groove 17 to guide the water in the first water receiving area 13 to the drainage groove 17. By providing the protruding structure 20 on the bottom wall of the first water receiving area 13, the protruding structure 20 can guide the water flow, so that the water in the first water receiving area 13 flows along the edge of the protruding structure 20 when close to the protruding structure 20, and the protruding structure 20 guides the part of the water flow to the drainage groove 17 to leave the first water receiving area 13, so that the water in the first water receiving area 13 is discharged more quickly; and the drainage port 28 defined by the protruding structure 20 can increase the shear force of the water when the water flows through the drainage port 28, so that the water in the first water receiving area 13 can be quickly guided to the drainage groove 17 through the drainage effect of the drainage port 28, and then flows into the second water receiving area 15 through the drainage groove 17, thereby improving the discharge speed of the water in the first water receiving area 13 and more fully avoiding water overflow in the first water receiving area 13.

[0064] When the heat exchanger assembly 40 generates condensed water, the condensed water drips downward into the first water receiving area 13 under the action of its own gravity, and flows in the first water receiving area 13 and is guided by the protruding structure 20 to flow to the drainage port 28. The water flowing through the drainage port 28 has reduced tension and increased shear force, and the water flow is faster and more easily flows into the drainage groove 17 through the drainage port 28, and then flows to the second water receiving area 15.

[0065] According to some embodiments of the present application, referring to Figure 10 The width of the drainage port 28 is a, and the value of a is in the range of 3mm to 6mm. For example, the value of a can be 3mm, 4mm, 5mm, 6mm, etc. By making the width a of the drainage port 28 not less than 3mm, the drainage port 28 can have sufficient width to allow water flow, so that the water flow in the first water receiving area 13 can smoothly flow into the second water receiving area 15 through the drainage port 28; by making the width a of the drainage port 28 not greater than 6mm, the drainage port 28 can ensure that the water in the first water receiving area 13 can smoothly flow into the second water receiving area 15 through the drainage hole, while making the opening of the drainage port 28 relatively narrow, more fully increasing the shear force of the water, and improving the flow speed when the water flows through the drainage port 28.

[0066] According to some embodiments of the present application, referring to Figures 9-12 Each drainage groove 17 corresponds to at least one drainage port 28. The shear force of the water can be increased when the water flows through the drainage port 28, and by making each drainage groove 17 correspond to at least one drainage port 28, the speed of the water in the first water receiving area 13 when flowing into the drainage groove 17 can be improved, more fully allowing the water in the first water receiving area 13 to be quickly discharged, and avoiding water overflow in the first water receiving area 13 due to excessive water in the first water receiving area 13.

[0067] According to some embodiments of the present application, referring to Figures 9-12 The convex structure 20 includes a sealing rib structure 21 and a drainage boss 27, and the bottom of the heat exchanger assembly 40 is supported on the sealing rib structure 21. The sealing rib structure 21 includes a first sealing rib 22 arranged along the length direction of the water collecting groove 12. The first sealing rib 22 is located at one end of the first water collecting area 13 close to the second water collecting area 15. Part of the drainage groove 17 is formed on the first sealing rib 22. The drainage boss 27 is located on the side of the first sealing rib 22 away from the second water collecting area 15. The drainage boss 27 and the first sealing rib 22 define a drainage opening 28 therebetween. By making the convex structure 20 include the sealing rib structure 21, and the bottom of the heat exchanger assembly 40 is supported on the sealing rib structure 21, the sealing rib structure 21 can support the heat exchanger assembly 40 and improve the sealing performance between the heat exchanger assembly 40 and the bottom plate component 11. The unheated airflow is prevented from passing between the heat exchanger assembly 40 and the bottom plate component 11. By making part of the drainage groove 17 formed on the first sealing rib 22, the processing of the drainage groove 17 is facilitated, and the drainage groove 17 can more easily guide the water in the first water collecting area 13 into the second water collecting area 15. By making the drainage boss 27 located on the side of the first sealing rib 22 away from the second water collecting area 15, and the drainage boss 27 and the first sealing rib 22 define the drainage opening 28 therebetween, the drainage boss 27 can be easily formed with the first sealing rib 22 to form a relatively narrow drainage opening 28. The drainage opening 28 can more fully increase the shear force of the water and improve the flow speed of the water flowing through the drainage opening 28 while ensuring that the water in the first water collecting area 13 can smoothly flow into the second water collecting area 15 through the drainage hole.

[0068] According to some embodiments of the present application, referring to Figures 9-12 One end of the drainage groove 17 located in the first water collecting area 13 is an inlet end 18, and the drainage boss 27 is located on the side of the inlet end 18 away from the second water collecting area 15. By making the drainage boss 27 located on the side of the inlet end 18 away from the second water collecting area 15, the drainage opening 28 can be located on the side of the first water collecting area 13 close to the second water collecting area 15, i.e., on the side close to the bottom. The water in the first water collecting area 13 can flow into the drainage groove 17 through the drainage opening 28 under the action of its own gravity, and the amount of water in the first water collecting area 13 is prevented from being excessive.

[0069] According to some embodiments of the present application, referring to Figures 9-12The plurality of drainage grooves 17 are arranged along the length direction of the water collecting groove 12, and the length direction of the water collecting groove 12 is perpendicular to the arrangement direction of the first water collecting area 13 and the second water collecting area 15. By arranging the plurality of drainage grooves 17 along the length direction of the water collecting groove 12, the water in the first water collecting area 13 can flow into the second water collecting area 15 through the drainage grooves 17 in the length direction of the water collecting groove 12, the draining speed of the water in the first water collecting area 13 is improved, and the condensate water on the outer side wall of the first water collecting area 13 caused by excessive water in the first water collecting area 13 is avoided.

[0070] Further, the plurality of drainage bosses 27 are arranged along the length direction of the water collecting groove 12, and the number of the drainage bosses 27 is the same as and one-to-one corresponds to the number of the drainage grooves 17, and at least one drainage opening 28 is defined between each drainage boss 27 and the first sealing protrusion 22. Figures 9-12 By arranging the plurality of drainage bosses 27 along the length direction of the water collecting groove 12, and the number of the drainage bosses 27 is the same as and one-to-one corresponds to the number of the drainage grooves 17, the water in the first water collecting area 13 can be better guided by the drainage bosses 27 to flow to the drainage openings 28 in the length direction of the water collecting groove 12, and can flow into the drainage grooves 17 through the drainage openings 28 to leave the first water collecting area 13, and the overflow of the water in the first water collecting area 13 caused by excessive water in the first water collecting area 13 is avoided.

[0071] According to some embodiments of the present application, referring to Figure 2 and Figure 3 , the air conditioner further comprises a protective net 31 installed on the bottom pan component 11 and located in the air outlet channel 30, and the back side of the drainage boss 27 is formed with a positioning hole 29 for positioning the protective net 31. By arranging the protective net 31, the protective net 31 can prevent the user's hand from being inserted into the air conditioner from the air outlet 10 of the air conditioner to cause injury. By forming the back side of the drainage boss 27 with the positioning hole 29 for positioning the protective net 31, the connection effect between the protective net 31 and the water collecting groove 12 at this position is better due to the thicker thickness of the water collecting groove 12 at this position, so that the connection between the protective net 31 and the water collecting groove 12 is more firm, and the protective net 31 is more firmly connected.

[0072] According to some embodiments of the present application, refer to Figures 2-8 The first sealing protruding rib 22 extends obliquely in the direction of approaching the second water receiving area 15 in the direction from top to bottom. By making the first sealing protruding rib 22 extend obliquely in the direction of approaching the second water receiving area 15 in the direction from top to bottom, by obliquely arranging the first sealing protruding rib 22, the condensed water attached to the first sealing protruding rib 22 can flow downward along the first sealing protruding rib 22 and in the direction of approaching the second water receiving area 15.

[0073] According to some embodiments of the present application, refer to Figures 9-12 The first sealing protruding rib 22 includes a plurality of first sub-sealing protruding ribs 23, and the plurality of first sub-sealing protruding ribs 23 are arranged at intervals in the length direction of the water receiving groove 12. Each first sub-sealing protruding rib 23 extends in the length direction of the water receiving groove 12, and a first communication port 24 is defined between adjacent two first sub-sealing protruding ribs 23, and the first communication port 24 communicates the first water receiving area 13 and the second water receiving area 15. By making the first sealing protruding rib 22 include a plurality of first sub-sealing protruding ribs 23, and by arranging the plurality of first sub-sealing protruding ribs 23 at intervals in the length direction of the water receiving groove 12, the first communication port 24 is defined between adjacent two first sub-sealing protruding ribs 23 in the length direction of the water receiving groove 12, and the first communication port 24 communicates the first water receiving area 13 and the second water receiving area 15, so that the water in the first water receiving area 13 can flow to the second water receiving area 15 under the action of its own gravity, and through the plurality of first communication ports 24 and the drainage groove 17, the water in the first water receiving area 13 can be discharged to the second water receiving area 15 more quickly.

[0074] For example, refer to Figure 7 The length of the first sub-sealing protruding rib 23 is c, and the value of c can be 100mm-200mm. By making the length c of the first sub-sealing protruding rib 23 not less than 100mm, the first sealing protruding rib 22 can play a better sealing role; by making the length c of the first sub-sealing protruding rib 23 not greater than 200mm, the number of the first communication ports 24 can be sufficient, the water in the first water receiving area 13 is close to the first communication port 24, and the water in the first water receiving area 13 can flow to the first communication port 24 more quickly.

[0075] According to some embodiments of the present application, refer to Figures 9-12 The first communication port 24 and the drainage groove 17 are arranged at intervals in the length direction of the water receiving groove 12.
