For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The air conditioner indoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0050] like Figure 1 and Figure 7 As shown, the air conditioner indoor unit 100 according to the embodiment of the utility model includes a shell 1, a top cover assembly 2, a water receiving tray 3 and a guide assembly 4.

[0051] Specifically, Figure 1 and Figure 5 As shown, the housing 1 can protect the internal structure of the air-conditioning indoor unit 100, preventing the internal structure of the air-conditioning indoor unit 100 from being exposed and damaged, which is beneficial to extending the service life of the air-conditioning indoor unit 100 and has a better appearance.

[0052] like Figure 1 and Figure 2 As shown, the top cover assembly 2 is disposed above the shell 1 and connected to the shell 1, and the top cover and the shell 1 together protect the internal structure of the air-conditioning indoor unit 100, avoiding damage caused by exposure of the internal structure of the air-conditioning indoor unit 100, which is beneficial to extending the service life of the air-conditioning indoor unit 100 and has a better appearance effect.

[0053] like Figure 7 As shown, the water receiving tray 3 is arranged in the shell 1 and is located below the heat exchanger of the air-conditioning indoor unit 100. The air flow entering the air-conditioning indoor unit 100 can flow through the heat exchanger and generate heat exchange with the heat exchanger to achieve heat exchange of the air flow entering the air-conditioning indoor unit 100.

[0054] In the cooling mode, refrigerant flows in the heat exchanger, and external air flows into the air conditioner indoor unit 100. The air flows toward the heat exchanger and exchanges heat with the refrigerant in the heat exchanger. The refrigerant in the heat exchanger evaporates and absorbs heat, and the air flow gradually becomes colder, generating a certain amount of condensed water on the outer surface of the heat exchanger. The condensed water flows downward under the action of gravity and is collected by the water receiving tray 3.

[0055] In the prior art, users may place flower pots on the top of the air conditioner indoor unit. When users water the flowers, water may overflow from the flower pots and flow on the top of the air conditioner indoor unit. Or when the user's area is relatively humid, water droplets may appear on the roof due to plum rain or the return of the south wind, and the water droplets may flow to the top of the air conditioner indoor unit. Water may flow along the shell to the ground, causing the floor to be dirty. Or water may enter the interior of the air conditioner indoor unit through the installation seam on the top of the air conditioner indoor unit, which may easily cause electrical hazards.

[0056] like Figure 8 As shown, the top cover assembly 2 has a vertical direction (such as Figure 1 The top cover assembly 2 is provided with a slit 221 (in the up and down directions shown in the figure) penetrating the top cover assembly 2, and the guide assembly 4 is arranged between the slit 221 and the water receiving tray 3, and is used for guiding the water entering the slit 221 to the water receiving tray 3. The water on the top cover assembly 2 can flow into the slit 221 and flow to the water receiving tray 3 along a fixed path through the guide assembly 4, which can prevent the water on the top cover assembly 2 from flowing along the shell 1 to the ground, thereby preventing the ground from being dirty; it can also prevent the water on the top cover assembly 2 from entering the area where the electrical components are provided in the air-conditioning indoor unit 100 through the slit 221, thereby avoiding electrical hazards.

[0057] According to the air-conditioning indoor unit 100 of the embodiment of the utility model, by arranging the guide component 4 between the gap 221 on the top cover component 2 and the water receiving tray 3 located in the shell 1, the water on the top cover component 2 can flow into the gap 221 and flow to the water receiving tray 3 along a fixed path through the guide component 4, which can prevent the water on the top cover component 2 from flowing along the shell 1 to the ground, thereby preventing the ground from being dirty; it can also prevent the water on the top cover component 2 from entering the area of ​​the air-conditioning indoor unit 100 where electrical components are provided through the gap 221, thereby avoiding electrical hazards.

[0058] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the top cover assembly 2 includes a top cover body 21 and a switch door 22. The top cover body 21 is provided with an upper air outlet 222. The switch door 22 is rotatably connected to the top cover body 21 and is used to open or close the upper air outlet 222. The switch door 22 is rotatably arranged at the upper air outlet 222 to open or close the upper air outlet 222, and the air outlet direction and air volume of the upper air outlet 222 can be controlled by rotation to achieve a variety of air flow circulation modes, thereby being able to meet different user needs. It can be understood that when the switch door 22 closes the upper air outlet 222, the air flow in the air duct is blown into the room through other air outlets to achieve indoor heating or cooling; when the switch door 22 opens the upper air outlet 222, the air flow in the air duct is blown into the room from the upper air outlet 222 and other air outlets at the same time, and the air is discharged from the top and other air outlets of the air conditioner indoor unit 100, thereby improving the cooling efficiency or heating efficiency of the air conditioner indoor unit 100 and improving the user experience. The gap between the switch door 22 and the top cover body 21 is configured as a gap 221 , and the gap between the switch door 22 and the top cover body 21 can make the switch door 22 rotate more smoothly.

[0059] In this embodiment, if Figure 8 and Fig. 9 As shown, the top cover body 21 includes a front top cover 211 and a rear top cover 212, the switch door 22 and the front top cover 211 are rotatably connected, and the front top cover 211 and the rear top cover 212 are detachably connected. After the front top cover 211 and the switch door 22 are rotated and worn, the top cover body 21 can only replace the front top cover 211, which can reduce the replacement cost of the top cover assembly 2.

[0060] In some embodiments of the utility model, the width of the gap 221 is 2-5mm. It is understandable that the width of the gap 221 can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm or 5mm. The width of the gap 221 is not less than 2mm, which can ensure the rotation gap between the switch door 22 and the top cover body 21, so as to achieve smooth rotation of the switch door 22; the width of the gap 221 is not more than 5mm, which can avoid the gap 221 on the top cover assembly 2 from being too large, making the top cover assembly 2 more beautiful.

[0061] In some embodiments of the present invention, Figure 4 , Fig.10 and Fig.11 As shown, the guide component 4 includes a first water receiving trough 41, which is arranged on the top cover component 2, and the first water receiving trough 41 extends along the length direction of the gap 221. The first water receiving trough 41 is located below the gap 221 and is arranged relative to the gap 221 in the up and down directions, and is used to receive water entering the gap 221. The first water receiving trough 41 can receive water flowing into the first water receiving trough 41 from various places of the gap 221, so as to prevent the water in the gap 221 from entering the air-conditioning indoor unit 100 from other positions, and can prevent water from entering the area of ​​the air-conditioning indoor unit 100 where electrical components are installed, so as to avoid electrical hazards. The bottom wall of the first water receiving trough 41 is provided with a first water outlet 412, and the water in the first water receiving trough 41 flows out of the first water receiving trough 41 from the first water outlet 412, so that the flow direction of the first water receiving trough 41 can be more reliable.

[0062] In this embodiment, if Figure 3 and Figure 4 As shown, the bottom wall of the first water receiving trough 41 is inclined upward compared to the horizontal plane, and the first water outlet 412 is arranged at the lowest point of the bottom wall of the first water receiving trough 41. The water in the first water receiving trough 41 flows to the lowest point under the action of gravity, and the water in the first water receiving trough 41 can flow out from the first water outlet 412 relatively smoothly.

[0063] In some embodiments of the present invention, Fig.12 As shown, the first water outlet 412 is provided with a first water nozzle 411 extending downward, so that the water flowing out of the first water outlet 412 can continue to flow downward along the first water nozzle 411 for a certain distance, so that the water flowing out of the first water outlet 412 can flow downward more uniformly.

[0064] Further, the angle between the lower end surface of the first water nozzle 411 and the horizontal plane is 10°-80°. It is understandable that the angle between the lower end surface of the first water nozzle 411 and the horizontal plane can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75° or 80°. The angle between the lower end surface of the first water nozzle 411 and the horizontal plane is not less than 10°, so that the water flowing out of the first water outlet 412 can be diverted to the lower end of the first water nozzle 411 (the lowest point of the first water nozzle 411), and the diversion effect of the first water nozzle 411 is better; the angle between the lower end surface of the first water nozzle 411 and the horizontal plane is not greater than 80°, which can prevent the lower end of the first water nozzle 411 from being sharp, avoid scratching the operator during installation, increase the safety of the first water nozzle 411, or try to avoid the first water nozzle 411 from being broken by force during transportation, thereby increasing the reliability of the first water nozzle 411.

[0065] In this embodiment, the angle between the lower end surface of the first water nozzle 411 and the horizontal plane is 15°, the first water nozzle 411 has a better diversion effect, and the first water nozzle 411 has better safety and reliability in use.

[0066] In some embodiments of the present invention, Figure 1 , Figure 4 and Fig.14 As shown, the shell 1 includes a panel bracket 11, and the guide component 4 includes a second water receiving groove 42. The second water receiving groove 42 is arranged on the panel bracket 11 and is located below the first water receiving groove 41. The second water receiving groove 42 and the first water outlet 412 are arranged relative to each other in the up and down directions, and are used to receive water flowing out of the first water receiving groove 41. The second water receiving groove 42 can receive water flowing into the second water receiving groove 42 from the first water outlet 412, so as to prevent the water in the first water receiving groove 41 from entering the air-conditioning indoor unit 100 from other positions, and to prevent water from entering the area of ​​the air-conditioning indoor unit 100 where electrical components are installed, so as to avoid electrical hazards. The bottom wall of the second water receiving groove 42 is provided with a second water outlet 422. The water in the second water receiving groove 42 flows out of the second water receiving groove 42 from the second water outlet 422, so that the flow direction of the second water receiving groove 42 can be more reliable.

[0067] In this embodiment, if Figure 1 , Fig.13 and Fig.14 As shown, a crossbeam 111 is disposed at the upper end of the panel bracket 11 , and the second water receiving tank 42 is disposed on the crossbeam 111 . The housing 1 further includes a panel 13 , and the panel bracket 11 is connected to the panel 13 .

[0068] In some embodiments of the present invention, Fig.14 As shown, the second water outlet 422 is provided with a second water nozzle 421 extending downward, so that the water flowing out of the second water outlet 422 can continue to flow downward along the second water nozzle 421 for a certain distance, so that the water flowing out of the second water outlet 422 can flow downward more uniformly.

[0069] Further, the angle between the lower end surface of the second water nozzle 421 and the horizontal plane is 10°-80°. It is understandable that the angle between the lower end surface of the second water nozzle 421 and the horizontal plane can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75° or 80°. The angle between the lower end surface of the second water nozzle 421 and the horizontal plane is not less than 10°, so that the water flowing out of the second water outlet 422 can be diverted to the lower end of the second water nozzle 421 (the lowest point of the second water nozzle 421), and the diversion effect of the second water nozzle 421 is better; the angle between the lower end surface of the second water nozzle 421 and the horizontal plane is not greater than 80°, which can avoid the lower end of the second water nozzle 421 being sharp, avoid scratching the operator during installation, increase the safety of the second water nozzle 421, or try to avoid the second water nozzle 421 from being broken by force during transportation, thereby increasing the reliability of the second water nozzle 421.

[0070] In this embodiment, the angle between the lower end surface of the second water nozzle 421 and the horizontal plane is 15°, the second water nozzle 421 has a better diversion effect, and the second water nozzle 421 has better safety and reliability in use.

[0071] In some embodiments of the present invention, the distance between the lower end surface of the first water spout 411 and the bottom wall of the second water receiving tank 42 in the vertical direction is 0-10 mm. It is understandable that the distance between the lower end surface of the first water spout 411 and the bottom wall of the second water receiving tank 42 in the vertical direction can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm. The distance between the lower end surface of the first water spout 411 and the bottom wall of the second water receiving tank 42 in the vertical direction is not greater than 10 mm, which can avoid the distance between the first water spout 411 and the bottom wall of the second water receiving tank 42 being too large, and can try to avoid the sound of water dripping from the first water outlet 412 being loud, thereby reducing the noise inside the air conditioner indoor unit 100.

[0072] In this embodiment, the distance between the lower end surface of the first water nozzle 411 and the bottom wall of the second water receiving groove 42 in the vertical direction is 5.8 mm, which can minimize the loud sound of water dripping from the first water outlet 412 and reduce the noise inside the air conditioning indoor unit 100.

[0073] In some embodiments of the present invention, Figure 4 , Figure 6 and Fig.15As shown, the shell 1 also includes an air outlet frame 12, which is arranged on the air inlet side of the panel bracket 11, and the guide component 4 includes a third water receiving trough 43, which is arranged on the air outlet frame 12 and below the second water receiving trough 42. The third water receiving trough 43 and the second water outlet 422 are arranged relative to each other in the up and down directions, and are used to receive water flowing out of the second water receiving trough 42. The third water receiving trough 43 can receive water flowing into the third water receiving trough 43 from the second water outlet 422, so as to prevent the water in the second water receiving trough 42 from entering the air-conditioning indoor unit 100 from other positions, so as to prevent water from entering the area of ​​the air-conditioning indoor unit 100 where electrical components are arranged, so as to avoid electrical hazards. The bottom wall of the third water receiving trough 43 is provided with a third water outlet 431, and the water in the third water receiving trough 43 flows out of the third water receiving trough 43 from the third water outlet 431, so that the flow direction of the third water receiving trough 43 can be more reliable.

[0074] In this embodiment, if Figure 4 As shown, the bottom wall of the third water receiving trough 43 is inclined upward compared to the horizontal plane, and the third water outlet 431 is arranged at the lowest point of the bottom wall of the third water receiving trough 43. The water in the third water receiving trough 43 flows to the lowest point under the action of gravity, and the water in the third water receiving trough 43 can flow out from the third water outlet 431 relatively smoothly.

[0075] Furthermore, if Figure 4 , Fig.16 and Fig.17 As shown, the third water outlet 431 includes a plurality of sub-water outlets 432 arranged along the width direction of the air outlet frame 12. The plurality of sub-water outlets 432 can decompose the water flowing out of the third water outlet 431 into a plurality of small water flows or water droplets, and try to avoid a large water flow out of the third water outlet 431, so that the water flow out of the sub-water outlet 432 can flow in the designed flow direction, so that the drainage direction of the third water outlet 431 is more reliable.

[0076] In some embodiments of the utility model, the width of the sub-outlet 432 is 1-5mm. It is understandable that the width of the sub-outlet 432 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm or 5mm. The width of the sub-outlet 432 is not less than 1mm, which can avoid the width of the sub-outlet 432 being smaller, and can avoid the water flowing out of the sub-outlet 432 at a slower speed, and avoid water overflowing from the third water receiving trough 43; the width of the sub-outlet 432 is not more than 5mm, which can decompose the water flowing out of the third water outlet 431 into multiple small water flows or water drops, and try to avoid a large water flow from the third water outlet 431, so that the water flowing out of the sub-outlet 432 can flow according to the designed flow direction, so that the drainage flow direction of the third water outlet 431 is more reliable.

[0077] In this embodiment, the width of the sub-outlet is 2 mm, which can prevent the water from flowing out of the sub-outlet 432 at a slow speed, prevent water from overflowing from the third water receiving trough 43, and try to avoid a large water flow out of the third water outlet 431, so that the water flowing out of the sub-outlet 432 can flow in the designed direction, making the drainage direction of the third water outlet 431 more reliable.

[0078] In some embodiments of the present invention, Fig.16 and Fig.17 As shown, the third water receiving trough 43 is located on the side of the air outlet frame 12 facing the panel bracket 11, and the third water outlet 431 is located at the end of the bottom wall of the third water receiving trough 43 away from the panel bracket 11, which is used to allow water flowing out of the third water outlet 431 to flow downward along the air outlet frame 12 toward the surface away from the panel bracket 11, so that the water flowing out of the third water outlet 431 can flow downward along the air outlet frame 12 toward the surface away from the panel bracket 11 according to the designed flow direction, so that the drainage direction of the third water outlet 431 is more reliable, and the water flows along the air outlet frame 12, which can avoid the water flowing out of the third water outlet 431 from dripping downward as much as possible, thereby reducing the dripping noise inside the air-conditioning indoor unit 100.

[0079] In some embodiments of the present invention, the distance between the lower end surface of the second water spout 421 and the bottom wall of the third water receiving tank 43 in the vertical direction is 0-10 mm. It is understandable that the distance between the lower end surface of the second water spout 421 and the bottom wall of the third water receiving tank 43 in the vertical direction can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm. The distance between the lower end surface of the second water spout 421 and the bottom wall of the third water receiving tank 43 in the vertical direction is not greater than 10 mm, which can avoid the distance between the second water spout 421 and the bottom wall of the third water receiving tank 43 being too large, and can try to avoid the loud sound of water dripping from the second water outlet 422, thereby reducing the noise inside the air conditioner indoor unit 100.

[0080] In this embodiment, the distance between the lower end surface of the second water nozzle 421 and the bottom wall of the third water receiving groove 43 in the vertical direction is 5.8 mm, which can minimize the loud sound of water dripping from the second water outlet 422 and reduce the noise inside the air conditioning indoor unit 100.

[0081] In some embodiments of the present invention, Figure 6 and Figure 7As shown, the guide component 4 also includes a fourth water receiving trough 44, which is arranged at the lower end of the air outlet frame 12, and is used to receive water flowing down from the air outlet frame 12. The fourth water receiving trough 44 can receive the water left from the air outlet frame 12 to prevent the water flowing down from the air outlet frame 12 from entering the area where electrical components are installed in the air-conditioning indoor unit 100, thereby avoiding electrical hazards. The fourth water receiving trough 44 is connected to the water receiving tray 3, and the water in the fourth water receiving trough 44 flows into the water receiving tray 3, so that the flow direction of the fourth water receiving trough 44 can be more reliable.

[0082] In this embodiment, if Figure 6 and Figure 7 As shown, a volute 5 is further provided between the fourth water receiving groove 44 and the water receiving tray 3, and a fourth water outlet 41 is provided on the fourth water receiving groove 44. The fourth water outlet 41 is provided corresponding to the guide groove 51 on the volute 5, and the guide groove 51 is inclined toward the direction of the water receiving tray 3. The water flowing out of the fourth water outlet 41 flows toward the water receiving tray 3 through the guidance of the guide groove 51, so that the drainage direction of the fourth water outlet 41 is more reliable.

[0083] In addition, a drain pipe is provided on the bottom wall of the water receiving tray 3, so that the accumulated water in the water receiving tray 3 can be discharged to the outside, so as to avoid the accumulated water from accumulating in the air conditioner indoor unit 100 for a long time, causing the air flow blown out by the air conditioner indoor unit 100 to be relatively humid.

[0084] In some embodiments of the utility model, the guide component 4 includes a hose, one end of the hose in the length direction is connected to the first water outlet 412, and the other end of the hose in the length direction is connected to the water receiving tray 3. The hose can directly guide the water flowing out of the first water outlet 412 to the water receiving tray 3, so that the water entering the gap 221 can be directly guided to the water receiving tray 3 through the first water receiving groove 41 on the guide component 4, which can prevent the water on the top cover component 2 from entering the area where the electrical components are provided in the air-conditioning indoor unit 100 through the gap 221, thereby avoiding electrical hazards.

[0085] The following describes an air conditioner indoor unit 100 according to a specific embodiment of the present invention with reference to the accompanying drawings.
