[0077] The air conditioner of the present disclosure performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0078] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0079] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature of the indoor space.

[0080] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0081] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0082] The indoor unit is connected to the outdoor unit, and the indoor unit and the outdoor unit are connected through a pipeline to transmit refrigerant.

[0083] In some embodiments, as shown in Figures 1 and 3, the indoor unit includes a shell 1, which is provided with an air inlet 11 and a first air outlet 12. The air flow outside the shell 1 enters the shell 1 through the air inlet 11 and is output to the outside of the shell 1 through the first air outlet 12.

[0084] In some embodiments, as shown in Figure 2, the indoor unit also includes a heat exchanger 2, which is configured to exchange heat with the air flow passing through it to form a heat exchange airflow; the heat exchanger 2 is located in the outer shell 1, and the air flow entering the outer shell 1 through the air inlet 11 is output from the outer shell 1 through the first air outlet 12 after heat exchange through the heat exchanger 2.

[0085] In some embodiments, as shown in Figures 2, 4, and 5, the indoor unit further includes a fan assembly 3, which includes a motor 31. The fan assembly 3 also includes a fan 32. The motor 31 can drive the fan 32 to rotate, so that external air flows into the housing 1 through the air inlet 11 and the air in the housing 1 is output from the first air outlet 12.

[0086] In some embodiments, as shown in Figures 2 and 14, the indoor unit further includes an electrical box 4, in which a circuit board 41 is provided. The circuit board 41 is integrated with components such as a controller to control the operation of the indoor unit.

[0087] In some embodiments, as shown in FIG. 2 and FIG. 13 , the indoor unit further includes a water receiving tray 6 , which is disposed at the bottom of the heat exchanger 2 and configured to collect water generated by defrosting the heat exchanger 2 .

[0088] In some embodiments, as shown in FIG. 1 and FIG. 3 , the indoor unit further includes a water pump assembly 5 , which includes a water pump 52 . The water pump 52 can discharge water in the water receiving tray 6 out of the indoor unit.

[0089] In some embodiments, as shown in FIG. 10A , the fan assembly may further include a mounting component, the mounting component being provided with at least one second opening 341 , and the mounting component being formed with a mounting area (eg, a fixed mounting area) and a third cavity (eg, a volute cavity).

[0090] In some embodiments, the motor 31 is disposed in the installation area, the fan is disposed in the third cavity, and the third cavity is communicated with the second opening 341 .

[0091] In some embodiments, the motor 31 is fixedly installed in the installation area formed by the installation component, and the fan is located in the third cavity formed in the installation component to meet the air supply requirements.

[0092] In some embodiments, as shown in FIG. 7 , the mounting component may be a split structure. For example, the mounting component may include a first mounting member 33 , on which a second volute portion 331 and a first sub-mounting member 332 are provided.

[0093] In some embodiments, as shown in FIG. 5 , the mounting component may further include a second mounting member 34 having a second opening 341 formed thereon, and a first volute portion 342 and a first support portion 343 provided on a first surface 2011 of the second mounting member 34 .

[0094] As shown in Figures 5 and 10A, the first support portion 343 protrudes from the first surface 2011. The interior of the first support portion 343 is a hollow structure. The second sub-mounting member 344 is disposed on the first support portion 343. A first rib 345 (first reinforcing rib) is disposed on the second surface of the second mounting member 34, and the first surface 2011 and the second surface 2012 are arranged in opposite directions.

[0095] For example, as shown in FIG5 , first surface 2011 and second surface 2012 are two side surfaces of the second mounting member 34 along the front-to-back direction. First surface 2011 is closer to first volute portion 342 than second surface 2012. As shown in FIG5 and FIG7 , first mounting member 33 is detachably mounted on second mounting member 34. A mounting area is formed between first sub-mounting member 332 and second sub-mounting member 344, and motor 31 is disposed in the mounting area. A third cavity is formed between second volute portion 331 and corresponding first volute portion 342. The third cavity communicates with the corresponding second opening 341. Fan 32 is disposed in the corresponding third cavity, and motor 31 is configured to drive fan 32 to rotate in the third cavity.

[0096] In some embodiments, as shown in Figures 1 to 3, the second mounting member 34 is disposed in the housing 1, dividing the interior of the housing 1 into a first cavity (e.g., an air inlet cavity) and a second cavity (e.g., an air outlet cavity), the air inlet 11 is connected to the first cavity, the first air outlet 12 is connected to the second cavity, the first surface 2011 is located in the first cavity, the second surface 2012 is located in the second cavity, and the heat exchanger 2 is located in the second cavity.

[0097] For example, a heat exchanger 2 and a fan assembly 3 are installed inside the shell 1. When the indoor unit is working, the fan assembly 3 will drive the airflow to flow inside the shell 1, so that the outside air enters the first cavity in the shell 1 through the air inlet 11. The outside air is driven by the fan 32 to enter the second cavity through the second opening 341. The outside air entering the shell 1 through the air inlet 11 exchanges heat with the heat exchanger 2, and the air after heat exchange is output to the outside through the first air outlet 12.

[0098] It should be noted that the fan assembly 3 needs to meet the requirements for installing the motor 31 and the fan 32.

[0099] In some embodiments, the second volute portion 331 provided on the first mounting member 33 cooperates with the first volute portion 342 provided on the second mounting member 34 to form a third cavity, and the fan 32 is located between the second volute portion 331 and the first volute portion 342. The fan 32 rotates in the third cavity so that air outside the third cavity is sucked into the third cavity and output through the second opening 341.

[0100] In some embodiments, as shown in FIG5 , due to the overall heavy weight of the motor 31, a first support portion 343 is formed at the portion where the second mounting member 34 is mounted and fixed to the motor 31. The first support portion 343 protrudes from the first surface 2011 of the second mounting member 34, thereby increasing the overall structural strength of the portion of the second mounting member 34 having the first support portion 343. This facilitates the transportation of the indoor unit, and the first support portion 343 supports the motor 31 when the indoor unit is transported.

[0101] In some embodiments, the second mounting member 34 includes a second sub-mounting member 344 . The first supporting portion 343 is provided with the second sub-mounting member 344 extending away from the second surface 2012 . The second sub-mounting member 344 is configured to mount and fix the motor 31 .

[0102] During the assembly of the motor 31, the first mounting member 33 and the second mounting member 34, the motor 31 is first placed on the second sub-mounting member 344 on the second mounting member 34, and then the first mounting member 33 is assembled to the second mounting member 34. In this way, the motor 31 is fixedly mounted between the first sub-mounting member 332 and the second sub-mounting member 344.

[0103] In some embodiments, the fan assembly 3 is fixedly mounted in the housing 1 via a second mounting member 34. The motor 31 is fixedly suspended on a second sub-mounting member 344 via a first sub-mounting member 332. The second sub-mounting member 344 is required to bear the weight of the motor 31 and the fan 32. The first support portion 343 provides sufficient strength support for the second sub-mounting member 344 to ensure that the structure meets the requirements of use. Because the second mounting member 34 needs to meet the installation requirements of the motor 31, the fan 32, and the first mounting member 33, the overall structural strength of the second mounting member 34 is required to be relatively high.

[0104] In some embodiments of the present disclosure, as shown in FIG. 10A , the second mounting member 34 further includes a first rib 345 , and at least one first rib 345 is formed on the second surface 2012 of the second mounting member 34 .

[0105] The first rib 345 is distributed on the side of the second mounting member 34 away from the first volute portion 342, the first support portion 343 and the second sub-mounting member 344. On the one hand, the first rib 345 can be used to improve the overall structural strength of the second mounting member 34 to meet the requirements for installation on the outer casing 1. On the other hand, the first rib 345 is arranged on the second surface 2012 of the second mounting member 34, which can simplify the structure of the first surface 2011 of the second mounting member 34.

[0106] In some embodiments, as shown in FIG9 , no ribs are formed on the outer surface of the first support portion 343 on the side away from the second surface 2012. This allows the structure of the first surface 2011 of the second mounting member 34 to be simplified as much as possible while still meeting the functional requirements of the mounting structure, thereby reducing the difficulty of manufacturing the second mounting member 34. It should be noted that the first surface 2011 of the second mounting member 34 is provided with a first volute portion 342 and a first support portion 343. These structures provide support for the fan 32 and the motor 31, thereby satisfying the structural support strength requirements of the second sub-mount 344 during installation and operation of the motor 31.

[0107] In some embodiments, the fan assembly 3 is assembled using a first mounting member 33 and a second mounting member 34 arranged vertically to form a volute for mounting the fan. Because the first and second mounting members 33, 34 are made of plastic, the second mounting member 34, particularly the second mounting member 34 configured to separate the housing 1, must meet the requirements for securing the fan assembly 3 within the housing 1. To ensure higher structural strength for the second mounting member 34, ribs are required on the sidewalls of the second mounting member 34 where the fan and motor are mounted. This makes the overall structure of the second mounting member 34 very complex, making it difficult to manufacture.

[0108] In order to solve the above technical problems, in some embodiments, as shown in Figures 10A and 10B, the first rib 345 extends in a direction away from the first surface 2011, and at least part of the first rib 345 in at least one first rib 345 has a first avoidance portion 3451 (for example, a first notch structure), and the first opening 3436 of the first avoidance portion 3451 is open toward the second cavity.

[0109] For example, by converting part of the first rib 345 into a first rib 345 having a first avoidance portion 3451, it is possible to provide the first avoidance portion 3451 on the first rib 345 in a specific area (for example, the area where the first rib 345 is close to the second opening 341). In this way, without increasing the density of the first rib 345, the structural strength of the first rib 345 in a specific area can be locally increased by increasing the first avoidance portion 3451 to achieve the requirement of increasing the structural strength of the area, thereby meeting the structural strength requirement and reducing the processing difficulty of the second mounting member 34.

[0110] In some embodiments of the present disclosure, as shown in FIG. 4 , a first connecting portion 3434 (eg, a connecting protrusion) is further provided between the first supporting portion 343 and the first volute portion 342 on the first surface 2011 of the second mounting member 34 .

[0111] In some embodiments, as shown in Figure 10A, a first accommodating portion 34341 recessed toward the first surface 2011 is provided on the second surface 2012 of the second mounting member 34, and a first rib 345 is also provided in the first accommodating portion 34341; and at least one first rib 345 is located in the first accommodating portion 34341, and the first rib 345 located in the first accommodating portion 34341 has a first avoidance portion 3451.

[0112] It should be noted that the first accommodation portion 34341 is formed in the first connection portion 3434 .

[0113] In some embodiments, as shown in Figures 4 and 10A, in order to increase the structural strength of the first connecting portion 3439, the second surface 2012 of the second mounting member 34 forms a first accommodating portion 34341, and a first rib 345 is arranged in the first accommodating portion 34341. The first avoidance portion 3451 formed by the first rib 345 can locally enhance the structural strength of the first connecting portion 3439.

[0114] In some embodiments of the present disclosure, as shown in FIG9 , the first support portion 343 is a hollow structure. A second rib 3431 (e.g., a second reinforcing rib) is disposed within the hollow structure of the first support portion 343. A third opening 3432 is also formed on the first support portion 343. The second rib 3431 extends from the inside to the outside of the hollow structure of the first support portion 343 toward the third opening 3432.

[0115] As for the second mounting part 34, it is usually made by injection molding. In order to facilitate demolding to reduce the difficulty of processing and increase the structural strength of the main body of the first support part 343, a second rib 3431 can be set in the hollow structure formed by the first support part 343. In this way, it is beneficial to improve the structural strength of the first support part 343 through the second rib 3431.

[0116] During the demolding process, the first support portion 343 can be smoothly demolded by utilizing the third opening 3432 formed by the first support portion 343. In addition, the second rib 3431 extends in a direction close to the third opening 3432, which also facilitates the smooth demolding of the second mounting member 34. In this way, the first support portion 343 can be achieved while meeting the structural strength while reducing the difficulty of processing and producing the first support portion 343.

[0117] In some embodiments of the present disclosure, as shown in FIG9 , the first support portion 343 extends perpendicularly to the width direction of the second mounting member 34, and the third opening 3432 is arranged at an end of the first support portion 343 away from the first mounting member 33. It should be noted that the width direction of the second mounting member 34 is substantially parallel to the axial direction of the fan 32, and the width direction of the second mounting member 34 is the left-right direction as shown in FIG5 .

[0118] The first support portion 343 is extended along the width direction of the second mounting member 34, so that in use, the first support portion 343 is arranged in a vertical direction, for example, the first support portion 343 is perpendicular to the second mounting member 34, so as to effectively improve the structural strength of the second mounting member 34 in the width direction of the second mounting member 34.

[0119] Correspondingly, in order to reduce the processing difficulty of the first support portion 343 and facilitate demolding, the third opening 3432 is arranged at the end of the first support portion 343 away from the first mounting member 33, and the second rib 3431 is also in an upright direction to facilitate demolding of the mold.

[0120] In some embodiments, as shown in FIG. 4 , the second rib 3431 has a second avoidance portion 3434 (eg, a second notch structure), and the fourth opening of the second avoidance portion 3434 faces the third opening 3432 ; the third opening 3432 is arranged at the end of the first support portion 343 away from the first mounting member 33 .

[0121] The second rib 3431 formed in the first support portion 343 has a relatively high overall height. The second avoidance portion 3434 can facilitate injection molding of the second rib 3431 on the one hand, and improve the structural strength of the second rib 3431 on the other hand, making it more conducive to demolding production.

[0122] In some embodiments of the present disclosure, as shown in Figures 5 and 6 , a second support portion 3435 is integrally formed on the first surface 2011 of the second mounting member 34. The second support portion 3435 is connected to an end of the first support portion 343 and extends along the width direction of the second mounting member 34 to an edge of the second mounting member 34. Here, the end of the first support portion 343 may be an end of the first support portion 343 away from the motor 31.

[0123] In some embodiments, the second support portion 3435 connected to the first support portion 343 extends to the edge of the second mounting member 34. The first support portion 343 and the second support portion 3435 cooperate to enhance the structural strength of the second mounting member 34 in its height direction. This effectively simplifies the structural complexity of the second mounting member 34 and reduces the difficulty of manufacturing the second mounting member 34 while still meeting the structural strength requirements of the second mounting member 34. It should be noted that the height direction of the second mounting member 34 is perpendicular to its width direction, and the height direction of the second mounting member 34 is the vertical direction as shown in FIG5 .

[0124] In some embodiments, as shown in FIG. 5 and FIG. 10A , a second receiving portion 34351 recessed toward the first surface 2011 is provided on the second surface 2012 of the second mounting member 34 , and the second receiving portion 34351 is formed in the second supporting portion 3435 .

[0125] For example, the second accommodating portion 34351 can meet the requirement of reducing the mass of the second supporting portion 3435, and during the injection molding process, the overall thickness of the second supporting portion 3435 matches that of the second mounting member 34, and can also reduce the impact of cooling and shrinkage of the injection molding material on the processing quality.

[0126] In some embodiments of the present disclosure, as shown in FIG. 5 and FIG. 10A , the first volute portion 342 is disposed on top of the second volute portion 331 , and the first volute portion 342 extends outward through the first surface 2011 of the second mounting member 34 to form an arc surface.

[0127] As shown in Figure 9, in order to improve the structural strength of the first volute part 342, a third rib 3421 (such as a third reinforcing rib) is provided on the surface of the first volute part 342 away from the second volute part 331. This arrangement can improve the structural strength of the first volute part 342.

[0128] In some embodiments, the third rib 3421 is arranged to extend along the extension direction of the first volute portion 342. Since the third rib 3421 is arranged in a vertical direction, it is convenient to demold the mold, which can effectively reduce the processing difficulty.

[0129] It should be noted that the end of the second volute portion 331 close to the first surface 2011 is the first end of the second volute portion 331, the end of the second volute portion 331 close to the seventh rib 338 is the second end, and the vertical direction of the third rib 3421 is the direction from the first end of the second volute portion 331 to the second end of the second volute portion 331.

[0130] In some embodiments, the second mounting member 34 , the second sub-mounting member 344 and the first volute portion 342 may be an integral member, which helps to improve the assembly efficiency of the second mounting member 34 .

[0131] In some embodiments, as shown in FIG5 , since the second mounting member 34 is integrally formed with the second sub-mounting member 344 and the first volute portion 342, a second connecting portion 346 may be provided between the second sub-mounting member 344 and two adjacent first volute portions 342 to improve the connection reliability between the second sub-mounting member 344 and the first volute portions 342. A fourth rib 3461 (e.g., a fourth reinforcing rib) is provided on a surface of the second connecting portion 346 away from the second volute portion 331. The fourth rib 3461 is arranged in a vertical direction.

[0132] In some embodiments, as shown in Figure 9, the second sub-mounting member 344 extends in a direction away from the first surface 2011 of the second mounting member 34, and the first volute portion 342 also extends in a direction away from the first surface 2011 of the second mounting member 34. The first end of the second sub-mounting member 344 is connected to the second mounting member 34, and the first end of the first volute portion 342 is also connected to the second mounting member 34. The second end of the second sub-mounting member 344 and the second end of the first volute portion 342 can be connected through the second connecting portion 346. In this way, the reliability of the connection between the second sub-mounting member 344 and the first volute portion 342 can be improved.

[0133] In some embodiments, as shown in FIG9 , a fourth rib 3461 is also provided on the surface of the second connecting portion 346 away from the first mounting member 33. The provision of the fourth rib 3461 enhances the structural strength of the first mounting member 33. Furthermore, the fourth rib 3461 is also arranged in a vertical orientation, facilitating demolding and effectively reducing processing difficulty.

[0134] In some embodiments, as shown in FIG. 9 , a fifth rib 3441 (eg, a fifth reinforcing rib) is provided on a surface of the second sub-mounting member 344 away from the first mounting member 33 .

[0135] The fifth rib 3441 is arranged in a vertical direction. Since the second sub-mount 344 needs to support the motor 31, it needs to have a high structural strength. To enhance the structural strength of the second sub-mount 344, the fifth rib 3441 can be provided on the second sub-mount 344. This improves the structural strength of the second sub-mount 344. To facilitate demolding of the second sub-mount 344 and reduce processing difficulty, the fifth rib 3441 is provided on the surface of the second sub-mount 344 away from the first mounting member 33.

[0136] In some embodiments, the fifth rib 3441 is arranged in a vertical direction. For example, the vertical direction of the fifth rib 3441 is perpendicular to the width direction of the second mounting member 34. In this way, demolding is facilitated during demolding, which can effectively reduce the difficulty of processing.

[0137] 9 and 10A , the edge of the second mounting member 34 away from the second volute portion 331 is provided with a first flange structure 347 . The surface of the first flange structure 347 away from the first volute portion 342 is provided with a sixth rib 3471 .

[0138] The second mounting member 34 is connected between the first plate 13 (e.g., bottom plate) of the shell 1 and the second plate 14 (e.g., top plate) of the shell 1. When the second mounting member 34 is connected to the second plate 14 of the shell 1, the connection area between the second mounting member 34 and the shell 1 can be increased through the first flange structure 347.

[0139] In some embodiments, the first flange structure 347 can be fixed to the second plate of the housing 1 by screws.

[0140] In some embodiments, in order to improve the structural strength of the first flange structure 347 , a sixth rib 3471 (eg, a sixth reinforcing rib) is provided on the outer surface of the first flange structure 347 .

[0141] In some embodiments, the sixth rib 3471 is arranged in a vertical direction. For example, the vertical direction of the sixth rib 3471 is roughly parallel to the vertical direction of the fifth rib 3441. In this way, demolding is convenient when the mold is demolded, which can effectively reduce the processing difficulty.

[0142] It can be understood that at least one of the second rib 3431, the third rib 3421, the fourth rib 3461, the fifth rib 3441 or the sixth rib 3471 configured on the second mounting member 34, when the indoor unit is hung and installed in use, the second rib 3431, the third rib 3421, the fourth rib 3461, the fifth rib 3441 and the sixth rib 3471 are in an upright arrangement, which can meet the requirements of the structural strength reinforcement design on the functional structure part extending outward from the second mounting member 34.

[0143] For example, the second rib 3431, the third rib 3421, the fourth rib 3461, the fifth rib 3441 and the sixth rib 3471 are arranged in an upright position, which can meet the structural strength design requirements of the second sub-mounting member 344, the second volute portion 331 and the first mounting member 33 extending outward from the second mounting member 34.

[0144] It should be noted that the second rib 3431, the third rib 3421, the fourth rib 3461, the fifth rib 3441 and the sixth rib 3471 are arranged in a vertical direction on the second mounting member 34, which can meet the requirements of smooth demoulding during the overall demoulding, simplify the structure of the mold and reduce the processing difficulty.

[0145] In some embodiments, as shown in FIG. 7 , in order to facilitate the assembly of the first mounting member 33 and the second mounting member 34 , a first clamping portion 333 and a first positioning portion 334 are provided on the first mounting member 33 .

[0146] As shown in FIG9 , the second mounting member 34 is provided with a second engaging portion 348 (e.g., an engaging portion), which is configured to engage with the first engaging portion 333. The second mounting member 34 is also provided with a third engaging portion 349, which is configured to engage with the first positioning portion 334.

[0147] It is understandable that in order to reduce the number of screws used and simplify the assembly process of the first mounting member 33 and the second mounting member 34, the first mounting member 33 and the second mounting member 34 can be pre-assembled together by snap-fitting.

[0148] It should be noted that the first clamping portion 333 and the second clamping portion 348 can be matched in various ways, such as a claw matching a slot, or a snap-fit ​​structure, etc., which will not be limited or elaborated here.

[0149] In some embodiments, as shown in FIG. 6 and FIG. 8 , a second positioning portion 330 (eg, a groove) is provided between two adjacent second volute portions 331 on the first mounting member 33 , and the second supporting portion 3435 is located in the second positioning portion 330 .

[0150] It should be noted that the second positioning portion 330 is configured to cooperate with the second support portion 3435 to allow the first mounting member 33 to slide on the second support portion 3435. In this way, when the first mounting member 33 is assembled to the second mounting member 34, the second support portion 3435 cooperates with the second positioning portion 330, allowing the first mounting member 33 to slide along the second support portion 3435 to be mounted on the second mounting member 34, which helps to improve the efficiency of mounting the first mounting member 33 to the second mounting member 34.

[0151] In some embodiments, as shown in FIG. 10A , a chamfered structure 34352 is formed between the second receiving portion 34351 and the second surface 2012 , and the chamfered structure 34352 extends from the first surface 2011 toward the second surface 2012 .

[0152] For example, the chamfered structures 34352 formed on both sides of the second accommodating portion 34351 are more conducive to the demolding process of the mold during production and processing.

[0153] In some embodiments, as shown in Figure 10A, the end face of the second support portion 3435 is provided with a fourth connecting portion 34353, the fourth connecting portion 34353 is connected and fixed to the outer shell 1, and the second mounting member 34 is provided with a first flange structure 347 at the edge away from the second volute portion 331, and the first flange structure 347 is provided with a fifth connecting portion 3472; the fifth connecting portion 3472 is connected and fixed to the outer shell 1.

[0154] In order to increase the coverage area of ​​the airflow output through the second opening 341, it is ensured that the heat exchanger 2 can exchange heat evenly, thereby improving the heat exchange efficiency.

[0155] In some embodiments, as shown in FIG. 15 , a third air guide 3411 is provided on the second mounting member 34 , and the third air guide 3411 is configured to guide at least part of the airflow output from the second opening 341 toward the outside of the second opening 341 and toward the heat exchanger 2 .

[0156] A third air guide portion 3411 is provided on the second surface 2012 of the second mounting member 34 at a position close to the edge of the second opening 341. The third air guide portion 3411 protrudes from the second surface 2012 of the second mounting member 34 and extends obliquely along the second opening 341 toward the first air outlet 12.

[0157] For example, the third air guide portion 3411 is formed on the second surface 2012 of the second mounting member 34 . The third air guide portion 3411 is arranged at the second opening 341 , thereby guiding the airflow output from the second opening 341 to flow toward the heat exchanger 2 .

[0158] In some embodiments, the third air guide portion 3411 is arranged in an inclined direction relative to the second surface 2012 of the second mounting member 34, and the airflow output through the second opening 341 will be transported outward along the surface of the third air guide portion 3411 toward the outside of the second opening 341. In this way, the coverage area of ​​the airflow output from the second opening 341 can be effectively increased, so that the heat exchanger 2 can exchange heat evenly without the need for additional complex air guide components. While meeting the air guide requirements, the overall structure of the second mounting member 34 is simplified, thereby reducing manufacturing costs.

[0159] In some embodiments, the third air guide portions 3411 are distributed on both sides of the second opening 341 ; the two third air guide portions 3411 on both sides of the same second opening 341 are arranged away from each other, the air guide portions 3411 are arranged tilted, and the third air guide portions 3411 extend toward the heat exchanger 2 .

[0160] It should be noted that for the same second opening 341, in the length direction of the heat exchanger 2, third air guides 3411 are respectively provided on both sides of the second opening 341, and the third air guides 3411 on both sides are arranged away from each other, so that the air outlet coverage area of ​​the second opening 341 can be increased.

[0161] In some embodiments, as shown in FIG. 10A and FIG. 15 , the at least one second opening 341 includes a plurality of second openings 341 , and the plurality of second openings 341 are arranged side by side along the length direction of the heat exchanger 2 .

[0162] In some embodiments of the present disclosure, as shown in Figures 8 and 13, in order to better guide the airflow driven by the fan 32 to flow toward the heat exchanger 2 through the second opening 341, a third connection portion 336 extending outward is also provided on the second volute portion 331 formed on the first mounting member 33. For example, the first end of the third connection portion 336 is connected to the second volute portion 331, and the second end of the third connection portion 336 extends along the length direction of the first mounting member 33 and in a direction away from the second volute portion 331. The third connection portion 336 is inserted into the second opening 341, and the third connection portion 336 extends along the front-to-back direction of the second mounting member 34 toward the direction close to the heat exchanger 2.

[0163] In some embodiments, when assembling the first mounting member 33 and the second mounting member 34, the first mounting member 33 can be inserted into the second opening 341 through the third connecting portion 336, and during the air supply process through the fan, the third connecting portion 336 forms a volute tongue structure to guide the airflow to be output through the second opening 341.

[0164] In some embodiments, as shown in FIG8 , a third accommodating portion 337 is provided on the third connecting portion 336 , a seventh rib 338 (eg, a seventh reinforcing rib) is provided in the third accommodating portion 337 , and the seventh rib 338 has a third avoidance portion 339 (eg, a third notch structure).

[0165] For example, since the second volute portion 331 is integrally formed on the first mounting member 33, in order to satisfy the formation of a volute tongue structure by the third connecting portion 336, the third connecting portion 336 forms a third accommodating portion 337, so that the surface of the third connecting portion 336 forms a curved surface of the volute tongue. In this way, the requirement for a relatively uniform overall thickness of the first mounting member 33 can also be met to improve the quality of injection molding.

[0166] It is understood that, as shown in Figure 8, the seventh rib 338 provided in the third accommodating portion 337 can enhance the structural strength of the third connecting portion 336. The third relief portion 339 formed on the seventh rib 338 not only enhances the structural strength of the seventh rib 338, but also ensures smooth demolding of the seventh rib 338 during demolding, thereby reducing the risk of cooling shrinkage.

[0167] In some embodiments, the following structure may be used to implement the installation and fixation of the motor 31 by the first sub-mounting member 332 and the second sub-mounting member 344 .

[0168] As shown in FIG. 7 , the first sub-mounting member 332 includes two first brackets 3321 (eg, frames) formed on the first mounting member 33 .

[0169] As shown in FIG. 5 , two first brackets 3321 are arranged side by side. The first brackets 3321 are in an arc-shaped structure. A second matching portion 3322 is provided between the two first brackets 3321 . The second matching portion 3322 extends along the axial direction of the motor 31 .

[0170] As shown in FIG. 9 , the second sub-mount 344 includes two second brackets 3442 formed on the second mounting member 34 .

[0171] The two second brackets 3442 are arranged side by side, and mounting grooves are formed on the surfaces of the second brackets 3442 opposite to the first brackets 3321. For example, the two second brackets 3442 correspond to the two first brackets 3321 respectively, and mounting grooves are formed on the opposite surfaces.

[0172] The first bracket 3321 and the second bracket 3442 are fixedly connected by screws, and the end of the motor 31 is fixed between the corresponding first bracket 3321 and the second bracket 3442.

[0173] In some embodiments, the motor 31 is installed between the first sub-mounting member 332 and the second sub-mounting member 344, and the first bracket 3321 formed by the first sub-mounting member 332 and the second bracket 3442 formed by the second sub-mounting member 344 clamp the corresponding ends of the motor 31 so that the motor 31 is fastened to the first sub-mounting member 332 and the second sub-mounting member 344.

[0174] Since the motor 31 is heavy, in order to improve the connection reliability between the first bracket 3321 and the second bracket 3442, after the first mounting member 33 and the second mounting member 34 are clamped together, the first bracket 3321 and the second bracket 3442 can be fastened together by screws to improve the connection reliability of the installation part of the motor 31.

[0175] In some embodiments, as shown in FIG6 , a shock absorber 311 (e.g., a shock absorbing ring) is provided on at least one end of the motor 31. A rotation stop 3443 is provided on at least one of the first sub-mounting member 332 or the second sub-mounting member 344. The rotation stop 3443 is connected to the shock absorber 311 and is configured to limit the rotation of the shock absorber 311 relative to the second mounting member 344. This helps prevent the motor 31 from rotating relative to the second mounting member 344 during operation.

[0176] It can be understood that the end of the motor 31 is provided with a shock absorber 311, which can play a shock-absorbing role during the operation of the motor 31. The shock absorber 311 is clamped between the first bracket 3321 and the second bracket 3442, and the motor 31 can be firmly fixed between the first bracket 3321 and the second bracket 3442.

[0177] It should be noted that since a stop portion 3443 is provided on at least one of the first bracket 3321 or the second bracket 3442, the stop portion 3443 cooperates with the shock absorber 311 to limit the rotation of the shock absorber 311 relative to the first bracket 3321 and the second bracket 3442, so as to ensure that the motor 31 does not rotate itself during operation.

[0178] In some embodiments, in order to ensure that the anti-rotation portion 3443 can limit the rotation of the shock absorber 311.

[0179] The anti-rotation portion 3443 can be configured as: a pressure rib provided on at least one of the first sub-mounting member 332 or the second sub-mounting member 344, and protruding from one of the first mounting member 332 and the second mounting member 344, and pressed on the outer circumference of the shock absorber 311 through the pressure rib to limit the rotation of the shock absorber 311.

[0180] In some embodiments, the anti-rotation portion 3443 can be a anti-rotation protrusion arranged on at least one of the first sub-mounting member 332 or the second sub-mounting member 344, and a anti-rotation groove is provided on the shock absorber 311, and the anti-rotation protrusion is stuck in the anti-rotation groove to limit the rotation of the shock absorber 311.

[0181] In some embodiments, when assembling the motor 31, after the first end of the first mounting member 33 is pre-installed on the second mounting member 34, the second end of the first mounting member 33 is tilted due to being blocked by the shock absorber 311. To ensure that the shock absorber 311 is effectively compressed, the tilt angle of the first mounting member 33 relative to the second mounting member 34 after pre-installation is greater than 3 degrees, and the tilt angle of the first mounting member 33 relative to the second mounting member 34 after pre-installation is less than 15 degrees.

[0182] In some embodiments, as shown in Figure 6, a first mating portion 3444 (e.g., a wiring portion) is provided on at least one of the second sub-mounting member 344 or the first volute portion 342, and the first mating portion 34444 (e.g., a mating portion) is configured to limit the wiring direction of the wires on the motor 31.

[0183] After the motor 31 is installed on the first mounting member 33 and the second mounting member 34 , the wires on the motor 31 also need to be connected to the circuit board 41 of the electrical box 4 , and the wires between the circuit board 41 and the motor 31 can be guided and routed through the first mating portion 3444 .

[0184] In some embodiments, the first mating portion 3444 is constructed as a structure such as a line card or a hook.

[0185] In some embodiments of the present disclosure, the housing 1 may adopt the following structural form.

[0186] As shown in FIG1 and FIG3 , in some embodiments, the housing 1 includes a first plate 13. The housing 1 also includes a second plate 14. The housing 1 also includes a third plate 15 (eg, a front panel), and the first air outlet 12 is provided on the third plate 15.

[0187] It should be noted that the third plate 15 is located between the first plate 13 and the second plate 14 .

[0188] During the assembly process, the second plate 14 can be turned upside down, and then the second mounting member 34, the third plate 15, the heat exchanger 2, the water pump assembly 5, the electrical box 4, the water receiving tray 6 and the first plate 13 are assembled in the installation order.

[0189] In some embodiments, in order to facilitate the assembly of the heat exchanger 2 onto the second plate 14, a fourth plate 16 (e.g., a side plate) may be provided at the first end of the second plate 14 to form a side wall of the outer shell 1, while the fourth plate 16 is not provided between the second end of the second plate 14 and the first plate 13 to form a vacant portion.

[0190] In this way, when assembling the heat exchanger 2 , the pipes 21 (eg, piping) on ​​the heat exchanger 2 do not need to be assembled by perforation, but can be directly placed on the end of the second plate 14 away from the fourth plate 16 .

[0191] For example, an installation gap is formed between the installation component, the second flange structure 17, the first plate 13 and the third plate 15, the pipe 21 extends to the outside of the shell 1 through the installation gap, and the seventh plate 51 (for example, a mounting plate) is arranged between the second flange structure 17 and the first plate 13 and covers the installation gap.

[0192] By arranging the fourth plate 16 at the first end of the second plate 14 to meet the requirement of connection with the first plate 13 , the second end of the second plate 14 is not directly connected to the first plate 13 , so that a gap is formed between the second end of the second plate 14 and the first plate 13 .

[0193] When assembling the heat exchanger 2, it is assembled on the inverted second plate 14, and the pipes 21 of the heat exchanger 2 can extend through the end of the second plate 14 away from the fourth plate 16. This allows the heat exchanger 2 to be directly assembled on the second plate 14 in a flat position without having to adjust its posture, enabling a single-person assembly operation, reducing assembly costs and improving assembly efficiency.

[0194] In some embodiments, as shown in Figure 11, the fourth plate 16 can be an integral structure with the second plate 14. For example, the first end of the second plate 14 can be bent to form the fourth plate 16. This helps to reduce the time for fixing the fourth plate 16 and the second plate 14.

[0195] In some embodiments, the fourth plate 16 and the second plate 14 may be separate structures. For example, the fourth plate 16 and the second plate 14 are fixed to the second plate 14 by screws.

[0196] During assembly, after the second plate 14 is inverted on the operating surface and the third plate 15 is assembled, the heat exchanger 2 can be assembled. For example, the heat exchanger 2 can be arranged horizontally and placed above the second plate 14 .

[0197] It should be noted that, as shown in FIG11 , the vacant area at the other end of the second plate 14 away from the fourth plate 16 can be used to meet the installation requirement of extending the pipe 21 of the heat exchanger 2 outside the shell 1 .

[0198] Compared with the indoor unit in the related art, in which side panels are respectively arranged on both sides of the second plate and a hole is opened in one of the two side panels for the pipe 21 to extend out, some embodiments of the air conditioner disclosed herein may not be provided with the fourth plate 16 on one side of the second plate 14. In this way, the heat exchanger 2 can be directly placed on the second plate 14 for assembly in a horizontal posture. Since there is no need to set a hole, it is beneficial to reduce production time.

[0199] In some embodiments of the present disclosure, as shown in FIG1 , in order to facilitate maintenance of the indoor unit, the first plate 13 is a split structure.

[0200] In some embodiments, the first plate 13 includes a first sub-plate 131 , and the first sub-plate 131 is arranged below the water receiving tray 6 .

[0201] In some embodiments, the first plate 13 further includes a second sub-plate 132 , and the second sub-plate 132 is arranged below the fan assembly 3 .

[0202] The second sub-board 132 can be detachably mounted on the first sub-board 131 . Thus, when repairing the fan assembly 3 , the second sub-board 132 can be directly mounted on the first sub-board 131 , and the fan assembly 3 can be repaired directly.

[0203] In some embodiments, as shown in FIG2 , in order to meet the screw-free design of the bottom appearance, a first plug-in portion 133 (e.g., a socket) is provided on the first sub-board 131, and a second plug-in portion 134 (e.g., a hook) is provided on the second sub-board 132. The second plug-in portion 134 is inserted into the first plug-in portion 133 to connect the first sub-board 131 and the second sub-board 132 together.

[0204] In some embodiments, the ends of the first sub-plate 131 and the second sub-plate 132 may be provided with folded edges so as to be fixedly connected to the fourth plate by screws.

[0205] In some embodiments, as shown in FIG1 , the first plate 13 further includes a sound insulating member 1331 (eg, a noise reduction plate). The sound insulating member 1331 can reduce the noise of the airflow sucked in by the air inlet 11 of the housing 1 .

[0206] In some embodiments, the sound insulation member 1331 is disposed on the inner edge of the first sub-panel 131 and is located above the second sub-panel 132 .

[0207] In some embodiments, after the housing 1 is hoisted into the user's home, for example, the housing 1 is hoisted on the ceiling, the second sub-panel 132 is disassembled to form the air inlet 11 .

[0208] In some embodiments, when air enters the bottom of the housing 1, wind noise is easily generated in the area between the inner edge of the first sub-board 131 and the mounting component. Noise reduction treatment is performed in this area through the sound insulation member 1331 to reduce the operating noise.

[0209] In some embodiments of the present disclosure, as shown in FIG. 3 , the water pump assembly 5 may include a seventh plate 51 , the water pump 52 is mounted on the seventh plate 51 , and the seventh plate 51 is mounted on the housing 1 .

[0210] In some embodiments, as shown in Figure 12, to facilitate assembly and disassembly of the water pump assembly 5, the seventh plate 51 employs a split structure. The seventh plate 51 may include a third sub-plate 513 (e.g., a first mounting sub-plate), on which the water pump 52 is mounted. The seventh plate 51 may also include a fourth sub-plate 514 (e.g., a second mounting sub-plate). The fourth sub-plate 514 is connected to at least one of the first plate 13, the third plate 15, or the mounting component.

[0211] For example, as shown in FIG. 12 , the third sub-board 513 is detachably disposed on the fourth sub-board 514 .

[0212] During assembly, after the heat exchanger 2 is assembled onto the second plate 14 , the third sub-plate 513 , the fourth sub-plate 514 and the water pump 52 are pre-assembled into independent components and then assembled onto the second plate 14 .

[0213] In this way, when repairing the water pump 52 later, it is only necessary to remove the third sub-board 513 from the fourth sub-board 514, and the third sub-board 513 and the water pump 52 can be removed from the outer shell 1 together to repair the water pump 52. The fourth sub-board 514 is still set on the outer shell 1 to meet the requirements of the overall installation of the outer shell 1.

[0214] In some embodiments, the detachable connection between the third sub-board 513 and the fourth sub-board 514 may be achieved by screws, snaps, etc., which are not limited here.

[0215] To facilitate assembly of the water pump 52 , as shown in FIG12 , in some embodiments, a third bracket 53 (eg, a pump bracket) is provided on the third sub-plate 513 . The third bracket 53 has a cantilever structure, and the water pump 52 is provided on the third bracket 53 .

[0216] For example, a third bracket 53 is provided on the inner surface of the third sub-board 513 close to the fan assembly 3 , and the third bracket 53 can separate the water pump 52 from the third sub-board 513 .

[0217] In some embodiments, as shown in Figure 3, a fourth bracket 54 (such as an extension bracket) is also provided on the cantilever structure, and the fourth bracket 54 extends toward the direction close to the water receiving tray 6. A sensor 55 (such as a water level sensor) is also provided on one end (such as the lower end) of the fourth bracket 54 close to the water receiving tray 6.

[0218] For example, the water pump 52 and the sensor 55 are centrally assembled on the third bracket 53, so that the water pump 52 and the sensor 55 are uniformly assembled through the seventh plate 51, realizing a modular design to improve assembly efficiency.

[0219] It should be noted that the housing 1 only needs to be configured with the fourth plate 16 on one side, without having to set the fourth plate 16 on both sides, and then drill holes in the fourth plate 16 to meet the installation requirements of the water pump 52, reducing the number of parts and improving assembly efficiency.

[0220] In some embodiments, a buffer component is further provided between the water pump 52 and the third bracket 53. The buffer component can buffer the vibration generated during the operation of the water pump 52, thereby reducing the noise caused by the vibration being transmitted to the third bracket 53.

[0221] In some embodiments, as shown in FIG3 , a water pump 52 is arranged at one end of the heat exchanger 2 , and the water pump 52 is located on the seventh plate 51 near the first air outlet 12 ; the pipe 21 is arranged between the water pump 52 and the mounting component.

[0222] For example, as shown in Figure 3, the water pump 52 is located on the seventh board 51, away from the electrical box 4, and the pipe 21 of the heat exchanger 2 is close to the electrical box 4. This makes it easier to connect the temperature sensor and electronic expansion valve installed on the pipe 21 to the circuit board 41 in the electrical box 4, facilitating assembly.

[0223] In some embodiments, as shown in Figures 11 and 12, after the water pump assembly 5 is assembled, the protruding pipe 21 is positioned by the seventh plate 51, the edge of the second flange structure 17 is provided with a first groove 171 (for example, a notched groove), and the edge of the seventh plate 51 is provided with a second groove 511 (for example, a notched groove), the first groove 171 and the second groove 511 are butt-jointed together, and the pipe 21 is located in the first groove 171 and the second groove 511.

[0224] For example, during assembly, the heat exchanger 2 is placed on the second plate 14, the pipe 21 is located in the corresponding first groove 171, and the water pump assembly 5 is installed on the second plate 14 through the seventh plate 51. The second groove 511 of the seventh plate 51 will mate with the first groove 171, so that the pipe 21 can be located between the seventh plate 51 and the second flange structure 17, thereby limiting the seventh plate 51 and the second flange structure 17.

[0225] In some embodiments of the present disclosure, as shown in FIG. 2 , the water receiving tray 6 is provided with a drain pipe 61 , and the drain pipe 61 extends to the outside of the housing 1 through the installation gap.

[0226] In some embodiments, as shown in Figure 12, since the drain pipe 61 also needs to extend to the outside of the outer shell 1, in order to position the drain pipe 61, a third groove 512 (notch groove) is also provided on the edge of the seventh plate 51. The drain pipe 61 is arranged in the third groove 512 and is located between the seventh plate 51 and the first plate 13.

[0227] In some embodiments, the positioning of the pipe 21 can also be achieved through the seventh plate 51. For example, a pipe hole is provided on the seventh plate 51, and the pipe 21 extends to the outside of the housing 1 through the pipe hole.

[0228] During assembly, after the heat exchanger 2 is mounted on the first plate 13, the water pump assembly 5 is assembled. The pipe holes provided on the seventh plate 51 of the water pump assembly 5 are aligned with the pipes 21, so that the pipes 21 are inserted into the corresponding pipe holes. The water pump assembly 5 is lightweight, making it easy to operate and adjust.

[0229] In some embodiments, as shown in FIG13 , an eighth rib 3410 (positioning rib) is provided on the mounting component, and the eighth rib 3410 is configured to support the water receiving tray 6 when the outer shell 1 is in an inverted state. It should be noted that, as shown in FIG6 , when the outer shell 1 is in an inverted state, it is convenient to install the heat exchanger 2, the water receiving tray 6 and the fan assembly 3.

[0230] In some embodiments, as shown in Figure 13, the eighth rib 3410 is further configured to press against the edge of the water tray 6 when the housing 1 is in an upright position. The eighth rib 3410 is formed on the second surface 2012 of the second mounting member 34 and extends toward the heat exchanger 2. The eighth rib 3410 extends above the edge of the water tray 6 and abuts against it. It should be noted that the pressing of the housing 1 against the edge of the water tray 6 when in an upright position helps prevent liquid from spilling out of the water tray 6 when the fan assembly 3 vibrates.

[0231] For example, the second surface 2012 of the second mounting member 34 is formed with an eighth rib 3410, which is arranged transversely and extends along the length of the water receiving tray 6. It should be noted that the length of the water receiving tray 6 is substantially the same as the axial direction of the motor 31.

[0232] During assembly, the second plate 14 is inverted and the second mounting member 34 and the heat exchanger 2 are assembled into the housing 1 . The water receiving tray 6 is inverted on the heat exchanger 2 , and the edge of the water receiving tray 6 rests on the eighth rib 3410 .

[0233] By providing the eighth rib 3410 on the mounting component, the eighth rib 3410 can support the edge of the water receiving pan 6 during the assembly process, so that the water receiving pan 6 can be placed on the eighth rib 3410 when the outer shell 1 is inverted for assembly. The eighth rib 3410 can cooperate with the heat exchanger 2 to reliably support the water receiving pan 6, thereby improving the assembly accuracy of the water receiving pan 6, thereby improving the assembly quality and thus improving the overall assembly quality of the indoor unit.

[0234] In some embodiments of the present disclosure, in order to reduce the number of screws used in the assembly process of the heat exchanger 2, the following structural improvements are made to the assembly method of the heat exchanger 2.

[0235] As shown in FIG. 11 , a first support member 18 is provided on one side of the housing 1 , and the first support member 18 is configured to support and install the heat exchanger 2 .

[0236] In some embodiments, as shown in FIG11 , a first sub-support member 181 (eg, a support component) may be provided on the first support member 18 , a threaded hole being provided at the first end of the first sub-support member 181 , and the first sub-support member 181 is configured to support the heat exchanger 2 .

[0237] In some embodiments, as shown in FIG. 11 , a first limiting portion 182 may be provided on the first support member 18 , and the first limiting portion 182 is configured to limit the heat exchanger 2 .

[0238] As shown in Figures 2 and 11, the first limiting portion 182 is located at the second end of the first sub-support member 181, the first end of the first end plate 22 is fixed to the first sub-support member 181 by screws, and the second end of the first end plate 22 is located between the first sub-support member 181 and the first limiting portion 182.

[0239] In some embodiments, as shown in Figure 11, the first sub-support member 181 can be a support rib formed on the first support member 18, with the inclination direction of the support rib being substantially the same as the inclination direction of the heat exchanger 2. The first stopper 182 can be a stopper provided on the first support member 18, disposed below the support rib. In some embodiments, as shown in Figure 11, the housing 1 is further provided with a second support member 19, the first end of which is provided with a threaded hole, and the first end of the second support member 19 serves as a pre-installation portion.

[0240] In some embodiments, a pre-assembled fitting portion is provided at the second end portion of the second end plate 23 , the pre-assembled fitting portion and the pre-assembled fitting portion are connected together, and the first end portion of the second end plate 23 is fixed to the second support member 19 by screws.

[0241] A first support member 18 and a second support member 19 are disposed opposite each other within the housing 1. Both support members can secure the end plates of the heat exchanger 2 with screws. During assembly, the end plates can be secured without the use of screws, which helps reduce the number of screws used during assembly of the heat exchanger 2 and shortens processing time.

[0242] For example, as shown in Figure 11, when installing the first end plate 22, the first end plate 22 will overlap the first sub-support member 181, and the first end plate 22 will be inserted into the area between the first sub-support member 181 and the first limiting portion 182, and then, the first end plate 22 will be fixed to the first sub-support member 181 by screws.

[0243] For example, as shown in FIG. 11 , when installing the second end plate 23 , the second end plate 23 is preassembled with the preinstallation portion through the preinstallation fitting portion, and then the second end plate 23 is fixed to the second support member 19 through screws.

[0244] For example, as shown in Figure 11, the first end plate 22 can be overlapped on the first sub-support member 181, the first end plate 22 can be inserted into the area between the first sub-support member 181 and the first limiting portion 182, and the first end plate 22 can be fixed to the first sub-support member 181 by screws, and the second end plate 23 can also be assembled together with the pre-installed fitting portion through the pre-installed portion, and then the second end plate 23 can be fixed to the second support member 19 by screws. In this way, since the two ends of the heat exchanger 2 are fixed respectively, it is beneficial to improve the stability of the heat exchanger 2.

[0245] It should be noted that after the assembly is completed and the hoisting installation is completed, the bottom of the first limiting portion 182 can support the first end plate 22, the second end plate 23 is assembled with the pre-installed portion through the pre-installed matching portion, and the second end plate 23 is fastened with the second support member 19 through screws to improve the assembly reliability.

[0246] In some embodiments, the first end of the first end plate 22 is fixed to the first support member 18 by screws, and the second end of the first end plate 22 is connected to the first support member 18 by a quick-release structure; the first end of the second end plate 23 is fixed to the second support member 19 by screws, and the second end of the second end plate 23 is connected to the second support member 19 by a quick-release structure. This helps to reduce the connection time of the connecting parts.

[0247] In some embodiments, two relatively arranged support members are provided in the housing 1, so that the first end of the heat exchanger 2 is fixedly connected to the corresponding support member by screws, while the second end of the heat exchanger 2 is not fixed by screws. For example, the first end of the heat exchanger 2 is limitedly matched with the support member. This is beneficial to reducing the connection of the connecting parts, improving the efficiency of fixing the heat exchanger 2, and reducing the installation time.

[0248] For example, when fixing the heat exchanger 2, at least one screw is provided on the end plates at both ends of the heat exchanger 2 to achieve fixed assembly of the heat exchanger 2, thereby reducing the number of screws used and improving assembly efficiency.

[0249] In some embodiments of the first sub-support, the pre-installed portion and the pre-installed matching portion are plugged together, for example, in a tongue-and-hole matching manner.

[0250] In some embodiments, the pre-installed portion and the pre-installed mating portion are clamped together, for example, in the manner of a claw and a slot.

[0251] In some embodiments, the pre-installed portion and the pre-installed mating portion overlap together.

[0252] In some embodiments, as shown in FIG11 , the second support member 19 may include a first connector 191 configured to connect to the heat exchanger 2 . The second support member 19 may also include a second connector 192 , which is arranged vertically. The first connector 191 is disposed on the second connector 192 (e.g., a structural reinforcement). It should be noted that the second connector 192 is vertically substantially parallel to the height direction of the second mounting member 34 .

[0253] In some embodiments, since the first support member 18 and the second support member 19 are arranged on both sides of the first air outlet 12, the second support member 19 needs to be assembled to the third plate 15 of the housing 1. The second connecting member 192 is a strip-shaped structure and is vertically arranged on one side of the first air outlet 12. This arrangement can improve the structural strength of the third plate 15.

[0254] It should be noted that the first support member 18 and the second support member 19 are arranged along the width direction of the second mounting member 34 .

[0255] In some embodiments, as shown in FIG. 11 , the housing 1 is provided with two opposing first flange plates 121 at the upper and lower portions of the first air outlet 12 in the height direction of the second mounting member 34 .

[0256] It should be noted that a first flange plate 121 may also be provided at either the upper portion of the first air outlet 12 or the lower portion of the first air outlet 12 in the height direction of the second mounting member 34 .

[0257] In some embodiments, the housing 1 is provided with a second flange plate 122 on one side of the first air outlet 12 .

[0258] In some embodiments, the second connecting member 192 is provided with a third flange plate 193 on one side of the first air outlet 12 .

[0259] The second flange plate 122 is arranged opposite to the third flange plate 193 . The first flange plate 121 , the second flange plate 122 and the third flange plate 193 extend to the outside of the first air outlet 12 .

[0260] In some cases, the flange plates (e.g., plates with holes) surrounding the first air outlet 12 can be used to connect to the indoor air duct during installation. The third flange plate 193 provided on the second connecting member 192 extends outside the first air outlet 12. This satisfies the requirements for air duct connection and improves the overall structural strength of the second connecting member 192.

[0261] In some embodiments of the present disclosure, the following structural configuration may also be adopted for the installation of the motor 31 .

[0262] As shown in FIG. 17 , the fan assembly 3 may further include a fixing portion 35 (fixing bracket), and the fixing portion 35 is configured to cooperate with the second mounting member 34 to fix the motor 31 .

[0263] In some embodiments, as shown in Figures 5, 16 and 17, a second volute portion 331 is formed on the first mounting member 33, a second opening 341 is provided on the second mounting member 34, a first volute portion 342 and a first support portion 343 are provided on the first surface 2011 of the second mounting member 34, and a second sub-mounting member 344 is provided on the first support portion 343.

[0264] The fixing portion 35 is detachably mounted on the second mounting member 34 . A mounting area is formed between the fixing portion 35 and the second sub-mounting member 344 , and the motor 31 is disposed in the mounting area.

[0265] In this way, the motor 31 can be installed and fixed by the independently configured fixing portion 35 cooperating with the second sub-mounting member 344 of the second mounting member 34 .

[0266] 9 , the second sub-mount 344 includes two second brackets 3442 formed on the second mounting member 34. The two second brackets 3442 are arranged side by side, and a clamp groove is formed on the surface of the second bracket 3442 opposite to the fixing portion 35.

[0267] It should be noted that the two second brackets 3442 are arranged along the width direction of the second mounting member 34 , and there is a gap between the two second brackets 3442 .

[0268] In some embodiments, as shown in FIG18 , the fixing portion 35 has a frame-like structure and includes a first sub-fixing portion 351. The fixing portion 35 also includes a second sub-fixing portion 352. The fixing portion 35 also includes two third sub-fixing portions 353 (e.g., clamp portions), which are connected between the first sub-fixing portion 351 and the second sub-fixing portion 352. The first sub-fixing portion 351 (first fixing portion) and the second sub-fixing portion 352 (second fixing portion) are fixedly connected to the second mounting member 34, and the ends of the motor 31 are fixed between the corresponding third sub-fixing portions 353 and the second bracket 3442.

[0269] For example, the two second brackets 3442 correspond to the two third sub-fixing portions 353, and the two ends of the motor 31 are respectively fixed between the corresponding two third sub-fixing portions 353 and the two second brackets 3442. As shown in Figure 17, during the assembly process of the motor 31, the motor 31 is installed between the fixing portion 35 and the second sub-mounting member 344. The third sub-fixing portions 353 formed by the fixing portion 35 and the second brackets 3442 formed by the second sub-mounting member 344 will clamp the corresponding ends of the motor 31, thereby fastening the motor 31 to the fixing portion 35 and the second sub-mounting member 344.

[0270] In some embodiments, since the motor 31 is heavy, in order to improve the connection reliability between the third sub-fixing portion 353 and the second bracket 3442, the fixing portion 35 can be fixed to the second mounting member 34 by screws to improve the connection reliability of the mounting portion of the motor 31.

[0271] In some embodiments, to save screws, as shown in FIG. 17 and FIG. 18 , a third plugging portion 354 extending outward is provided on the first sub-fixing portion 351 , and a fourth plugging portion 3433 is provided on the first supporting portion 343 .

[0272] For example, along the direction of the motor 31 pointing toward the first sub-fixing portion 351 , the first sub-fixing portion 351 is provided with a third plugging portion 354 .

[0273] In some embodiments, the third plug-in portion 354 is connected to the fourth plug-in portion 3433 , which helps save the use of screws.

[0274] In some embodiments, the third plug-in portion 354 of the fixing portion 35 is connected to the fourth plug-in portion 3433 , and the second sub-fixing portion 352 of the fixing portion 35 is fixed to the second mounting member 34 by screws.

[0275] For example, during the assembly of the motor 31, the motor 31 is placed between the two second brackets 3442 of the second mounting member 34, the third plug-in portion 354 of the fixing portion 35 is inserted into the fourth plug-in portion 3433, and the fixing portion 35 is flipped over so that the second sub-fixing portion 352 rests against the second connecting portion 346. The second sub-fixing portion 352 and the second connecting portion 346 are then fastened together with screws. This not only improves the stability of the connection between the fixing portion 35 and the second sub-mounting member 344, but also helps save screws. Due to the reduced use of screws, it also helps reduce the installation time of the fixing portion 35 and the second sub-mounting member 344.

[0276] In some embodiments of the present disclosure, as shown in FIG16 , a plurality of first volute portions 342 are formed on the second mounting member 34. To cooperate with the first volute portions 342, the indoor unit is configured with a plurality of first mounting members 33, such that the plurality of first volute portions 342 correspond to the plurality of first mounting members 33. It should be noted that each first mounting member 33 is provided with at least one second volute portion 331.

[0277] In some embodiments, a plurality of first volute portions 342 of an integral structure are formed on the second mounting member 34 , which is beneficial for improving the assembly efficiency of the first mounting member 34 and the second mounting member 33 .

[0278] In some embodiments, a plurality of second volute portions 331 are provided on the first mounting member 33 , and a plurality of first volute portions 342 are formed on the second mounting member 34 , such that the plurality of first volute portions 342 correspond to the plurality of second volute portions 331 .

[0279] During assembly, the motor 31 and fan 32 are placed on the second mounting member 34, and the at least one first mounting member 33 is assembled onto the second mounting member 34. The second volute portion 331 provided on the at least one first mounting member 33 cooperates with the first volute portion 342 at the corresponding position to form a third cavity, thereby meeting the installation requirements of the fan 32.

[0280] As for the installation and fixation of the motor 31 , the independently configured fixing portion 35 cooperates with the second sub-mounting member 344 of the second mounting member 34 to complete the installation and fixation of the motor 31 .

[0281] In some embodiments, the mounting component may include two first mounting members 33 , and the fixing portion 35 is disposed between the two first mounting members 33 .

[0282] In some embodiments, the mounting component may include a first mounting member 33 , and the first mounting member 33 is provided with a plurality of second volute portions 331 , so that the fixing portion 35 may be arranged between two adjacent second volute portions 331 on the first mounting member 33 .

[0283] In some embodiments, as shown in FIG. 17 , the fan assembly 3 further includes a support shaft 36 , and the fan 32 is disposed on the support shaft 36 . The fan 32 is connected to the rotating shaft of the motor 31 through the support shaft 36 to achieve power transmission.

[0284] In some embodiments, as shown in Figure 17, when the same support shaft 36 is configured with multiple fans 32, the fan assembly 3 also includes a bearing 37, the first end of the support shaft 36 is connected to the rotating shaft of the motor 31 through a coupling, and the second end of the support shaft 36 is supported by the bearing 37.

[0285] In some embodiments, as shown in Figure 17, the fan assembly 3 also includes multiple fans 32, two adjacent fans 32 among the multiple fans 32 are connected together through a support shaft 36, the first end of the support shaft 36 is connected to the rotating shaft of the motor 31, and the second end of the support shaft 36 is provided with a bearing 37.

[0286] In some embodiments, as shown in FIG17 , a fifth bracket 335 (e.g., a mounting bracket) is provided on at least one second volute portion 331. The fifth bracket 335 is configured to mount a bearing 37 on the support shaft 36. A sixth bracket 340 (e.g., a mounting bracket) is provided on the second mounting member 34. The sixth bracket 340 is configured to mount a bearing 37 on the support shaft 36. The bearing 37 is located between the fifth bracket 335 and the sixth bracket 340.

[0287] When two adjacent fans 32 among multiple fans 32 are installed and supported by the same support shaft 36, the bearing 37 supports the second end of the support shaft 36 to ensure that the support shaft 36 can drive the two fans 32 to rotate smoothly in their respective third chambers.

[0288] During assembly, the motor 31 and fan 32 are placed at corresponding positions on the second mounting member 34, and the bearing 37 disposed at the free end of the support shaft 36 is placed on the sixth bracket 340. The first mounting member 33 is assembled to the second mounting member 34 so that the bearing 37 can be fixedly mounted between the fifth bracket 335 and the sixth bracket 340.

[0289] The fifth bracket 335 and the sixth bracket 340 are connected together, and the bearing 37 is fixedly installed therebetween. In this way, there is no need to configure additional components to separately install the bearing 37, thereby reducing the number of parts and improving assembly efficiency.

[0290] In some embodiments, the fan assembly 3 further includes a shock absorbing component 38 . The shock absorbing component 38 is disposed between the fifth bracket 335 and the sixth bracket 340 . The shock absorbing component 38 is an annular structure and is sleeved on the bearing 37 .

[0291] The outer sleeve of the bearing 37 is provided with a shock-absorbing component 38, and the bearing 37 is fixed between the fifth bracket 335 and the sixth bracket 340 through the shock-absorbing component 38. In this way, the reliability of the bearing 37 can be improved, the service life of the bearing 37 can be extended, and the noise generated by the vibration of the bearing 37 during operation can be reduced.

[0292] It should be noted that when the motor 31 drives the support shaft 36 to rotate, the vibration generated by the fan 32 during the air supply process is transmitted to the bearing 37 via the support shaft 36. The bearing 37 is surrounded by a shock-absorbing component 38 and is disposed between the fifth bracket 335 and the sixth bracket 340. The shock-absorbing component 38 cushions the vibration generated by the bearing 37, thereby reducing noise and extending the service life of the bearing 37.

[0293] 17 and 19 , to facilitate assembly of the shock absorbing component 38, a second stopper 381 is provided on the shock absorbing component 38. The second stopper 381 extends toward the exterior of the shock absorbing component 38. For example, the second stopper 381 extends toward the direction of the shock absorbing component 38 away from the first surface 2011 of the second mounting member 34.

[0294] In some embodiments, as shown in FIG17 , the sixth bracket 340 is provided with a fourth slot 3401 (limiting slot), and the second limiting portion 381 is inserted into the fourth slot 3401. For example, during assembly, the second limiting portion 381 of the shock absorbing component 38 is inserted into the fourth slot 3401, so that the shock absorbing component 38 is pre-assembled onto the sixth bracket 340. The first mounting member 33 is fixed to the second mounting member 34, so that the shock absorbing component 38 can be accurately sandwiched between the fifth bracket 335 and the sixth bracket 340, thereby ensuring that the bearing 37 is accurately installed in place.

[0295] In some embodiments of the present disclosure, as shown in FIG. 20 , the interior of the housing 1 is separated by a second mounting member 34 to form a first cavity and a second cavity. The electrical box 4 is located on the first cavity side and connected to the first surface 2011 of the second mounting member 34 .

[0296] In some embodiments, as shown in Figures 14 and 17, in order to reduce the possibility of the second mounting member 34 catching fire due to a cable malfunction, a fireproof component 40 is provided on the second mounting member 34, a sixth accommodating portion 401 is provided on the fireproof component 40, and the electrical box 4 is provided on the fireproof component 40. Part of the cables are arranged in the first cavity and the second cavity via the sixth accommodating portion 401.

[0297] In some embodiments, the mounting member and the electrical box 4 are sequentially connected and located between two sides of the housing 1. The interior of the housing 1 is located on the first side of the mounting member as a first cavity, and on the second side of the mounting member as a second cavity.

[0298] In some embodiments, as shown in FIG20 , the electrical box 4 is disposed within the mounting member, near the mounting member and near the water pump assembly 5 . The first panel mounting member and the electrical box 4 are docked together, cooperating to separate the interior of the housing 1 into a first chamber and a second chamber. The mounting member and the electrical box 4 are arranged sequentially along the length of the first panel 13 of the housing 1 . The second panel 14 of the housing 1 may only cover the mounting member, while the electrical box 4 may be exposed outside the second panel 14 .

[0299] It should be noted that by arranging the mounting components and the electrical box 4 in sequence along the length direction of the outer shell 1, so as to utilize the electrical box 4 and the mounting components to be separated in the outer shell 1 to form a first cavity and a second cavity, the space occupied by the electrical box 4 in the outer shell 1 can be fully utilized to form a first cavity and a second cavity separated from each other in the outer shell 1, thereby shortening the overall length of the mounting components and reducing the manufacturing cost of the indoor unit.

[0300] In some embodiments, as shown in Figure 14, the electrical box 4 may include a circuit board 41. The circuit board 41 is configured to meet the requirements of connecting the indoor unit to an external power supply and controlling the operation of the indoor unit.

[0301] In some embodiments, as shown in FIG14 , the electrical box 4 may further include a box body 42 . The box body 42 , as the main structure of the electrical box 4 , is configured to carry and mount a circuit board 41 . The box body 42 is mounted on the housing 1 , and the circuit board 41 is mounted in the box body 42 .

[0302] In some embodiments, the electrical box 4 may further include a box cover 43. The box cover 43 can cover the circuit board 41 installed in the box body 42. The box cover 43 is installed on the box body 42 and covers the circuit board 41.

[0303] In some embodiments, the box body 42 has two fifth plates 422 (for example, side plates), and the two fifth plates 422 are respectively arranged on both sides of the sixth plate 421 (for example, a support plate), and an installation and maintenance area is formed between the two fifth plates 422; the circuit board 41 is arranged on the sixth plate 421, and the box cover 43 is arranged between the two fifth plates 422.

[0304] For example, during assembly, the box body 42 is docked with the second mounting member 34 via the sixth plate 421 and installed together on the second plate 14 of the housing 1 to assemble the electrical box 4 to the housing 1 .

[0305] In some embodiments, as shown in Figure 14 , the top of the box body 42 is fixedly connected to the outer housing 1 , and the lower end of the box cover 43 is provided with a seventh connecting portion 431 (bend). The seventh connecting portion 431 is connected between the lower ends of the two fifth plates 422 . An electrical appliance chamber is formed between the box body 42 , the box cover 43 , and the second plate 14 of the outer housing 1 .

[0306] For example, the first side of the box body 42, facing away from the circuit board 41, is flat. On the second side of the box body 42, facing the circuit board 41, the sixth plate 421 is recessed in a direction toward the sixth plate 421, creating a space for accommodating the circuit board 41. The box body 42 has open top and bottom ends. The box body 42 is mounted on the second plate 14 of the housing 1, with the open top portion of the box body 42 covered by the second plate 14. A cover 43 is mounted on the box body 42, with the seventh connecting portion 431 of the cover 43 covering the open bottom portion of the box body 42.

[0307] In some embodiments, as shown in Figures 1, 13, and 14, a sixth connecting portion 423 is further provided on a side of the sixth plate 421 away from the cover 43. The edge (e.g., the inner edge) of the first sub-plate 131 proximal to the heat exchanger 2 is connected to the second mounting member 34, the sixth connecting portion 423, and the fifth plate 422; the inner edge of the second sub-plate 132 is connected to the first sub-plate 131, the sixth connecting portion 423, and the sixth plate 421.

[0308] In some embodiments, as shown in FIG14 , a sixth accommodating portion 401 is provided on the edge of a fifth plate 422 of the box body 42 close to the heat exchanger 2 , and the sixth accommodating portion 401 is used to allow the cables of the electrical components in the second cavity to pass into the electrical box 4 .

[0309] In some embodiments, a fourth accommodating portion 402 (first wire threading portion) is provided on the sixth plate 421 . The fourth accommodating portion 402 is configured to allow cables to pass through the electrical box 4 and be led out and arranged inside the housing 1 .

[0310] In some embodiments, a fifth accommodating portion 403 (eg, a second wire threading portion) is provided on a fifth plate 422 of the box body 42 away from the heat exchanger 2 . The fifth accommodating portion 403 is configured to allow cables to pass through the electrical box 4 and extend to the outside of the housing 1 .

[0311] In some embodiments, as shown in Figures 21 and 22, the housing 1 is in the shape of a rectangular box, and an air inlet 11 is provided on the rear side of the housing 1. The air inlet 11 is configured to allow indoor air to enter the housing 1. A first air outlet 12 is provided on the front side of the housing 1. The first air outlet 12 is configured to circulate processed indoor air into the indoor space.

[0312] In some embodiments, the air inlet 11 may be provided corresponding to the air inlet grille on the wall, and the first air outlet 12 is connected to the room through a pipe.

[0313] In some embodiments, as shown in FIG23 , a partition 103 is provided inside the housing 1 , and the partition 103 separates the space inside the housing 1 into a first cavity and a second cavity.

[0314] The air inlet 11 is located on the side wall of the first cavity, and the first air outlet 12 is located on the side wall of the second cavity.

[0315] For example, the partition 103 further includes a second opening 341 , and the first cavity and the second cavity are communicated through the second opening 341 .

[0316] In some embodiments, the indoor unit may further include a fan assembly 3 , which includes a fan configured to drive the flow of air so that the air in the indoor space enters the housing 1 through the air inlet 11 and is blown out through the first air outlet 12 .

[0317] For example, the fan can be a centrifugal fan 100, with the outlet of the centrifugal fan 100 corresponding to the second opening 341 on the partition 103. The centrifugal fan 100 can be located in the first chamber, and the centrifugal fan 100 blows the air in the first chamber into the second chamber. In some embodiments, as shown in FIG23 , the heat exchanger 2 is located between the outlet of the centrifugal fan 100 and the first air outlet 12. The heat exchanger 2 is configured to absorb heat from the air blown by the centrifugal fan 100 or transfer heat to the air.

[0318] In some embodiments, a water receiving tray 6 is provided below the heat exchanger 2 to collect water condensed in the heat exchanger 2. The water receiving tray 6 is connected to the outside of the housing 1 and can discharge the water in the water receiving tray 6 to the outside of the housing 1.

[0319] For example, the drain pan 6 communicates with a drain hose connected to the outside of the housing 1 .

[0320] When the indoor unit is working, the centrifugal fan 100 runs, so that the air in the indoor space enters the first chamber through the air inlet 11, then passes through the centrifugal fan 100 and flows to the heat exchanger 2. After exchanging heat with the heat exchanger 2, the air is sent to the indoor space through the first air outlet 12.

[0321] As shown in FIG. 23 and FIG. 24 , a centrifugal fan 100 according to some embodiments of the present disclosure includes a volute 110 and an impeller 120 .

[0322] The impeller 120 is connected to the output shaft of the motor 31 and can rotate when driven by the motor 31 .

[0323] In some embodiments, as shown in FIG24 , the volute 110 includes a volute body 111 (e.g., a cylindrical portion). The volute body 111 is cylindrical, and the impeller 120 is disposed within the volute body 111. Suction ports are provided on both axial sides of the volute body 111, respectively, and are configured to allow air to flow into the volute 110.

[0324] The volute 110 also includes an air outlet portion 112, which extends toward the first air outlet 12. An end of the air outlet portion 112 close to the second cavity forms a second air outlet 1121 of the volute 110. The air flow in the volute 110 flows into the indoor space through the second air outlet 1121.

[0325] By simulating the outlet end of the centrifugal fan in the related art: as shown in Figures 25A and 25B, it can be seen from the figures that the outlet turbulence intensity and vortex intensity of the centrifugal fan are relatively high, and the outlet airflow is unstable.

[0326] In centrifugal fan 100, air enters impeller 120 axially. The centrifugal force of centrifugal fan 100 changes the direction of the airflow, for example, flowing radially from centrifugal fan 100 before being discharged through second air outlet 1121. Because impeller 120 has a finite number of blades, there are gaps in the actual airflow. This discontinuity in the blades affects the airflow, resulting in unstable airflow velocity. This causes the airflow at different times at second air outlet 1121 to affect each other, generating noise.

[0327] To address the noise problem caused by unstable airflow at the second air outlet 1121 of the centrifugal fan 100 of an air conditioner, some embodiments of the present disclosure provide an air conditioner. For example, the centrifugal fan 100 can be used in air conditioners, air purifiers, fresh air blowers, full heat exchangers, etc., to drive air flow.

[0328] In some embodiments, as shown in FIG. 26 to FIG. 28 , the air outlet portion 112 includes a first side wall 113 , and the first side wall 113 is formed by extending from the volute tongue of the volute 110 toward the first air outlet 12 .

[0329] For example, as shown in FIG. 24 , the first side wall 113 is the lower side wall of the air outlet portion 112 .

[0330] In some embodiments, as shown in FIG27 , a plurality of first air guides 1130 (e.g., notches) are provided at one end of the first sidewall 113 near the first air outlet 12. The plurality of first air guides are spaced apart from one another along the axial direction of the centrifugal fan 100. The first air guides 1130 may have a sawtooth shape, a blunt petal shape, or a sinusoidal wave shape. The first air guides 1130 can comb and break up vortices, thereby refining large vortices and reducing the vortex volume and turbulence intensity at the second air outlet 1121, thereby reducing outlet flow noise.

[0331] Taking the serrated first air guide portion 1130 as an example, as shown in Figures 27 and 28, the edge width D2 of the first air guide portion 1130, if D2 is too large, for example, D2 is greater than 20 mm, then the arrangement of the first air guide portion 1130 is relatively sparse, resulting in a weakened combing effect; if D2 is too small, for example, D2 is less than 5 mm, then the arrangement of the first air guide portion 1130 is relatively compact, and due to the small spacing between the first air guide portions 1130, the structural strength of the serrations will be reduced, making it easy to break.

[0332] It should be noted that increasing D2 improves the structural strength of the sawtooth. Decreasing D2 increases the number of first air guides 1130, reducing vorticity and turbulence intensity, and thus reducing outlet flow noise. For example, when D2 is greater than or equal to 5 mm and less than or equal to 20 mm, the structural strength of the sawtooth is maintained while also reducing airflow noise.

[0333] In some embodiments, as shown in FIG28 , the end of the first air guide portion 1130 closer to the first air outlet 12 is the first end, the end of the first air guide portion 1130 farther from the first air outlet 12 is the second end, and the length from the first end of the first air guide portion 1130 to the second end of the first air guide portion 1130 is H. If H is too large, the length of the first air guide portion 1130 in the airflow direction is relatively large, which fails to improve the combing effect of the first air guide portion and may reduce the structural strength of the first sidewall 113 due to the excessive length of the first air guide portion 1130. If H is too small, the length of the first air guide portion 1130 in the airflow direction is relatively small, which may reduce the combing effect of the first air guide portion 1130.

[0334] For example, if H satisfies the relationship: 0.8×D2≤H≤1.2×D2, the structural strength of the first side wall 113 can be ensured, and the eddy current can be combed.

[0335] In some embodiments, the distance between two adjacent first air guide portions 1130 is D1, and D1 satisfies the relationship: D2≤D1≤1.5×D2. The size relationship between D1 and D2 determines the density between the first air guide portions 1130, and maximizes the combing effect of the first air guide portions 1130 while ensuring the strength of the edge of the first side wall 113.

[0336] It is understandable that if D1 is too large, the arrangement of the first air guide parts 1130 will be relatively sparse, and the combing effect will inevitably be weakened; if D1 is too small, the arrangement of the first air guide parts 1130 will be relatively compact, and the structural strength of the serrations between the first air guide parts 1130 will be reduced and easy to break.

[0337] In some embodiments, the end of the first side wall 113 having the first air guide portion 1130 close to the first air outlet 12 is rounded, such as the tip of a sawtooth is rounded, so as to avoid danger caused by the tip.

[0338] In some embodiments, the first air guides 1130 are arranged non-uniformly on the first sidewall 113 along the axial direction of the centrifugal fan 100 .

[0339] It should be noted that the density of the arrangement of the first air guides 1130 corresponds to the working area at the second air outlet 1121 of the centrifugal fan 100 .

[0340] As shown in Figure 29, the lighter the color at the second air outlet 1121 of the volute 110, the greater the flow rate. As can be seen from the figure, the flow rate in the middle of the second air outlet 1121 is relatively high, while the flow rate on both sides of the middle is relatively low. Therefore, in some embodiments of the present disclosure, the first air guides 1130 in the middle of the first sidewall 113 can be smaller in size and denser in number, so that the denser first air guides 1130 can be used to sort out the areas with higher flow rates.

[0341] In some embodiments, as shown in FIG30 , the edge of the first sidewall 113 includes a first region 1131 (e.g., a first notch region), a second region 1132 (e.g., a second notch region), and a third region 1133 (e.g., a third notch region). The second region 1132 is located in the middle and between the first region 1131 and the third region 1133.

[0342] As shown in FIG. 32 , the first air guide portion in the second area 1132 is defined as a first sub-air guide portion 1136 , and the first air guide portions in the first area 1131 and the third area 1133 are defined as second sub-air guide portions 1137 .

[0343] In some embodiments, as shown in FIG30 , the distance between two adjacent first sub-air guides 1136 is d11, and the distance between two adjacent second sub-air guides 1137 is d12, where d11 is smaller than d12. Thus, the first sub-air guides 1136 in the second region 1132 are densely packed, while the second sub-air guides 1137 in the first region 1131 and the third region 1133 are sparsely packed, allowing for targeted arrangement based on the size of the working area.

[0344] For example, the first air guide portion is relatively dense where the working area is large, so that the combing effect can be ensured; the first air guide portion is relatively sparse where the working area is small, so that the structural strength of the first side wall 113 can be improved and the service life of the first side wall 113 can be extended.

[0345] In some embodiments, as shown in FIG31 , the plane where the first side wall 113 is located is defined as a reference plane, and the projection area of ​​the second sub-air guide portion 1137 on the reference plane is larger than the projection area of ​​the first sub-air guide portion 1136 on the reference plane.

[0346] For example, the edge width d12 of the second sub-air guide portion 1137 is greater than the edge width d11 of the first sub-air guide portion 1136. In this way, the density of the first sub-air guide portion 1136 and the second sub-air guide portion 1137 can be distinguished.

[0347] In some embodiments, as shown in FIG31 , the edge of the first sidewall 113 further includes a fourth region 1134 and a fifth region 1135. The fourth region 1134 and the second region 1132 are respectively located on either side of the first region 1131, and the fifth region 1135 and the second region 1132 are respectively located on either side of the third region 1133. For example, the fourth region 1134 and the fifth region 1135 are respectively located at both ends of the first sidewall 113.

[0348] It should be noted that the size and arrangement of the first air guide portion 1130 in the fourth area 1134 and the first air guide portion 1130 in the fifth area 1135 are the same as those of the first air guide portion 1130 in the second area 1132 .

[0349] In some embodiments, as shown in FIG. 32 , the size of each portion of the second sub-air guide portion 1137 is 1.2 to 2.5 times the size of each portion of the first sub-air guide portion 1136 .

[0350] If the ratio of the size of each portion of the second sub-air guide 1137 to the size of each portion of the first sub-air guide 1136 is less than 1.2 times, it is impossible to distinguish the density of the first sub-air guide 1136 from the second sub-air guide 1137. If the size of each portion of the second sub-air guide 1137 is greater than 2.5 times the size of each portion of the first sub-air guide 1136, the second sub-air guide 1137 will be arranged more sparsely, which will weaken the combing effect.

[0351] It should be noted that the edge width of the second sub-air guide 1137 is greater than the edge width of the first sub-notch 1136, and the distance between two adjacent second sub-notches 1137 is greater than the distance between two adjacent first sub-notches 1136. The length from the edge to the root of the second sub-notch 1137 is greater than that of the first sub-notch 1136.

[0352] 33 to 35 , the air outlet 112 further includes a second side wall 114 , which is opposite to the first side wall 113 . For example, the first side wall 113 is closer to the water receiving tray 6 than the second side wall 114 .

[0353] The inner surface of the second sidewall 114 is provided with a plurality of recessed second air guides 1140 (e.g., combing grooves). The second air guides 1140 extend in the same direction as the airflow. For example, the second air guides 1140 extend along the second air outlet 1121 toward the first air outlet 12.

[0354] The second air guide portion 1140 can comb the airflow near the second side wall 114 at the second air outlet 1121 to improve the stability of the airflow at the second air outlet 1121 and reduce the noise of the airflow.

[0355] In some embodiments, the second air guiding portion 1140 may be arc-shaped in a cross section perpendicular to the airflow direction.

[0356] As shown in FIG35 , the length D3 of the second air guide 1140 is greater than or equal to 10 mm to ensure that the second air guide 1140 combs the airflow. If D3 is less than 10 mm, the length of the second air guide 1140 is too short, which will reduce the combing effect. If D3 is greater than 80 mm, the length of the second air guide 1140 is too long, which will reduce the structural strength of the second sidewall 114.

[0357] For example, if D3 satisfies the relationship: 20 mm ≤ D3 ≤ 80 mm, the structural strength of the second side wall 114 can be ensured, and the combing effect of the second air guide portion 1140 on the airflow can also be ensured.

[0358] The slot width D5 of the second air guide 1140 satisfies the relationship: 1mm≤D5≤5mm, and the slot spacing D4 satisfies the relationship: 1mm≤D4≤10mm. By setting the width of the second air guide 1140 relatively narrow, the spacing can be arranged more closely, thereby improving the airflow combing effect of the second air guide 1140.

[0359] In some embodiments, the depth T of the second air guide 1140 increases along the direction of airflow. Thus, the depth of the second air guide 1140 near the volute body 111 is shallow, allowing airflow to flow smoothly into the second air guide 1140. Furthermore, the depth of the second air guide 1140 is only relatively deep at the outlet, minimizing the impact of the second air guide 1140 on the structural strength of the second sidewall 114.

[0360] For example, the depth T of the second air guide portion 1140 satisfies the relationship: 0.8×D5≤T≤1.5×D5, thereby maximizing the combing effect on the airflow while ensuring structural strength. If the depth is too large, the structural strength of the second sidewall 114 will be affected, while if the depth is too small, the combing effect will not be achieved.

[0361] In some embodiments, the second air guide portions 1140 may also be arranged in a sparse or dense manner according to the working area at the second air outlet 1121 , similar to the first air guide portions 1130 .

[0362] As shown in FIG. 29 , it can be seen that the working area at the top of the second air outlet 1121 of the volute 110 is relatively long in the axial direction of the centrifugal motor 100 , and therefore the second air guide portion 1140 can be evenly arranged.

[0363] In some embodiments, the air flow velocity at the left and right ends of the second air outlet 1121 close to the second side wall 114 is relatively low, and the second air guide parts 1140 at the left and right ends of the second side wall 114 can be arranged more sparsely, for example, the intervals between the second air guide parts 1140 are large.
