The main body 100 can have a front side and a back side arranged opposite to each other. The side of the main body 100 facing the user can be the front side of the main body 100. The front side of the main body 100 to the back side of the main body 100 can be the front-back direction of the main body 100. The height direction, the length direction and the front-back direction of the main body 100 can be perpendicular to each other.

[0071] In some embodiments, the air conditioner indoor unit can be arranged horizontally, that is, the length direction of the main body 100 can be parallel to the horizontal plane.

[0072] In some embodiments, the air conditioner indoor unit can be arranged obliquely, that is, the length direction of the main body 100 can form a certain angle with the horizontal plane.

[0073] In some embodiments, referring to FIGS. 1 and 4, the main body 100 can include at least a first cavity 101. The first cavity 101 can be located in the main body 100. The main body 100 can include a cabinet 1. Referring to FIG. 2, an indoor air inlet 111 can be formed on the cabinet 1. The indoor air inlet 111 can be an entrance for air to enter the cabinet 1. Referring to FIG. 4, the indoor air inlet 111 can communicate with the first cavity 101.

[0074] In some embodiments, referring to FIG. 3, an indoor air outlet 112 can be formed on the cabinet 1. The indoor air outlet 112 can be an exit for air to flow out of the cabinet 1. Referring to FIG. 4, the indoor air outlet 112 can communicate with the first cavity 101.

[0075] In some embodiments, continuing to refer to FIG. 4, the indoor air inlet 111 can be arranged at the top of the casing 1 to appropriately increase the distance between the indoor air inlet 111 and the ground, thereby reducing the suction of dust and ensuring better air quality.

[0076] In some embodiments, the indoor air outlet 112 can be arranged at the lower portion of the front side of the casing 1, so that when the hanging type air conditioner indoor unit is hung on a wall or other support, the distance between the indoor air outlet 112 and the wall or other support can be appropriately increased, so as to reduce the air at the indoor air outlet 112 blowing to the wall or other support on which the hanging type air conditioner indoor unit is arranged, thereby reducing the loss of air blown out by the indoor air outlet 112, and then ensuring that more and more efficient air blown out by the indoor air outlet 112 blows into the indoor space for cooling or heating treatment.

[0077] In some embodiments, continuing to refer to FIG. 4, the main body 100 can include an indoor heat exchanger 21. The indoor heat exchanger 21 can be arranged in the first cavity 101. The indoor heat exchanger 21 can be configured to exchange heat with the air in the first cavity 101.

[0078] In some embodiments, continuing to refer to FIG. 4, the main body 100 can include an indoor fan 22. The indoor fan 22 can be arranged in the first cavity 101. The indoor fan 22 can be configured to provide power for the flow of air. In this case,

[0079] In some embodiments, continuing to refer to FIG. 4, the indoor fan 22 can be arranged on the side of the indoor heat exchanger 21 away from the indoor air inlet 111. The indoor fan 22 causes the air to enter the first cavity 101 through the indoor air inlet 111 and exchange heat with the indoor heat exchanger 21. The air after exchanging heat with the indoor heat exchanger 21 flows out of the casing 1 through the indoor air outlet 112.

[0080] In some embodiments, the air conditioner outdoor unit (not shown in the figure) can include an outdoor casing. The outdoor casing can be provided with an outdoor containing space. The air conditioner outdoor unit can include an outdoor heat exchanger. The outdoor heat exchanger can be arranged in the outdoor containing space.

In this case, the outdoor casing can be provided with an outdoor air inlet. The outdoor air inlet can be in communication with the outdoor containing space. The outdoor air inlet can be configured to introduce outdoor air into the outdoor containing space. The outdoor casing can be provided with an outdoor air outlet. The outdoor air outlet can be in communication with the outdoor containing space. The outdoor air outlet can be configured to introduce the air in the outdoor containing space out of the outdoor containing space.

[0081] In the present disclosure, rotation of the outdoor fan causes outdoor air to enter the outdoor containing space from the outdoor air inlet, exchange heat with the outdoor heat exchanger, and then flow out of the outdoor containing space from the outdoor air outlet.

[0082] In some embodiments, the air conditioner can include a compressor (not shown in the figure). The compressor can be disposed in the outdoor containing space. The air conditioner can include a throttling device (not shown in the figure). The throttling device is configured to throttle. The throttling device can be disposed in the outdoor containing space.

[0083] In some embodiments, in both the indoor heat exchanger 21 and the outdoor heat exchanger (not shown in the figure), one is a condenser and the other is an evaporator.

[0084] In the present disclosure, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been adjusted and heat exchanged. Among them, the compressor compresses the refrigerant gas in a low-temperature and low-pressure state to discharge refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The throttling device expands the high-temperature and high-pressure state liquid phase refrigerant condensed in the condenser into a low-pressure liquid phase refrigerant. The evaporator evaporates the refrigerant expanded in the throttling device, and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with the material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0085] In some embodiments, when the indoor heat exchanger 21 is used as a condenser and the outdoor heat exchanger is used as an evaporator, the air conditioner is used as a heater in a heating mode; when the indoor heat exchanger 21 is used as an evaporator and the outdoor heat exchanger is used as a condenser, the air conditioner is used as a cooler in a cooling mode.

[0086] In some embodiments, the main body 100 can include a fresh air device. The fresh air device can be configured to introduce outdoor fresh air into the room. Referring to FIG. 5, the fresh air device can include a fresh air scroll 6. The fresh air scroll 6 can be located in the cabinet 1. Referring to FIG. 47, a fresh air cavity 60 can be formed in the fresh air scroll 6, and the fresh air cavity 60 can be in communication with the outdoors.

[0087] In some embodiments, referring to FIG. 47, the fresh air device can include a fresh air fan 7, which can be disposed in the fresh air cavity 60. In this regard, referring to FIG. 47, the fresh air device can include a fresh air motor 8. The fresh air motor 8 can be connected to the fresh air fan 7. The fresh air motor 8 drives the fresh air fan 7 to rotate to cause outdoor air to flow into the fresh air cavity 60 and then into the room. That is, the fresh air motor 8 can drive the fresh air fan 7 to rotate to cause outdoor air to flow into the first cavity 101 through the fresh air cavity 60, mix with indoor air entering the first cavity 101, and then flow into the room through the indoor air outlet 112.

[0088] In some embodiments, referring to FIGS. 46 and 47, the fresh air volute 6 can be formed with a fresh air inlet 61 and a fresh air outlet 62. The fresh air motor 8 drives the fresh air fan 7 to rotate to cause outdoor air to flow into the fresh air cavity 60 through the fresh air inlet 61 and then flow into the room through the fresh air outlet 62.

[0089] In some embodiments, referring to FIG. 6, the main body 100 can include a base 3. The base 3 can be formed with a volute tongue air duct 31. The base 3 can also be formed with a motor cavity 32. The volute tongue air duct 31 and the motor cavity 32 can be sequentially arranged along the length direction of the main body 100.

[0090] In some embodiments, referring to FIG. 7, the indoor air blower 22 can include an indoor fan 221. The indoor fan 221 can be disposed in the volute tongue air duct 31. The indoor air blower 22 can also include an indoor motor 222. The indoor motor 222 can be located in the motor cavity 32. Since the volute tongue air duct 31 and the motor cavity 32 are sequentially arranged along the length direction of the main body 100, when the indoor fan 221 is disposed in the volute tongue air duct 31 and the indoor motor 222 is located in the motor cavity 32, the indoor fan 221 and the indoor motor 222 can also be understood as being sequentially arranged along the length direction of the main body 100.

[0091] In the present disclosure, the indoor motor 222 drives the indoor fan 221 to rotate to cause air to flow to the indoor heat exchanger 21 through the indoor air inlet 111, exchange heat with the indoor heat exchanger 21, and then flow out of the casing 1 through the indoor air outlet 112.

[0092] In some embodiments, referring to FIG. 9, the main body 100 can include a water collecting tray 33. The water collecting tray 33 can be formed on the base 3. The water collecting tray 33 can be configured to collect condensed water left on the indoor heat exchanger 21.

[0093] In some embodiments, referring to FIG. 9, the main body 100 can comprise a drainage portion 34. The drainage portion 34 can be formed on the base 3. For example, referring to FIG. 48, the drainage portion 34 can comprise a drainage portion side wall and a drainage portion bottom wall, and the drainage portion 34 can be a groove formed by the drainage portion side wall and the drainage portion bottom wall, so as to accommodate the condensed water and reduce or avoid the spread of the condensed water in the casing 1.

[0094] In some embodiments, referring to FIG. 9, the drainage portion 34 can be located on the side of the motor cavity 32 away from the indoor fan 221. The drainage portion 34 can be in communication with the water pan 33. Referring to FIG. 17, the bottom wall of the drainage portion 34 can be provided with a drainage hole 341. The drainage hole 341 is configured to drain water. The water in the water pan 33 can be discharged through the drainage hole 341.

[0095] In the present disclosure, since the indoor motor 222 is located in the motor cavity 32, by arranging the drainage portion 34 on the side of the motor cavity 32 away from the indoor fan 221, the drainage portion 34 can be located on the side of the indoor motor 222 away from the indoor fan 221, i.e., the drainage portion 34 and the indoor motor 222 can be arranged in a staggered manner along the length direction of the main body 100. When the water collects in the drainage portion 34, since the drainage portion 34 is arranged offset from the indoor motor 222 along the length direction of the main body 100, the condensed water in the drainage portion 34 is offset from below the indoor motor 222, which can reduce or avoid the condensed water in the drainage portion 34 splashing onto the indoor motor 222, thereby reducing or avoiding the water causing the indoor motor 222 to burn out after being powered on, and thus ensuring the normal operation and service life of the indoor motor 222.

[0096] It should be understood that the indoor motor 222 can comprise a motor rotating shaft (not shown in the figure). The indoor motor 222 operates to rotate the motor rotating shaft, which can be connected with the indoor fan 221, and the rotation of the motor rotating shaft drives the indoor fan 221 to rotate.

[0097] In some embodiments, referring to FIG. 8, the indoor motor 222 can be an outer rotor motor. The outer rotor motor can comprise a stator 2221. The outer rotor motor can comprise a rotor 2222. The stator 2221 can be fixedly arranged in the motor cavity 32. The rotor 2222 can be arranged on the outer side of the stator 2221 along the circumferential direction of the stator 2221. The rotor 2222 can be connected with the indoor fan 221. The stator 2221 drives the rotor 2222 to rotate, and the rotor 2222 drives the indoor fan 221 to rotate.

[0098] It should be understood that when the indoor motor 222 is an outer rotor motor, there is a gap between the stator 2221 and the rotor 2222, which can be referred to as an air gap, and the function of the air gap is to allow the rotor 2222 to rotate freely in the cavity of the stator 2221.

[0099] In some embodiments, when the indoor motor 222 is an outer rotor motor, the drainage portion 34 is arranged on the side of the motor cavity 32 away from the indoor fan 221, so that when the condensed water collects in the drainage portion 34, the condensed water in the drainage portion 34 deviates from the lower side of the indoor motor 222, thereby reducing or avoiding the condensed water in the drainage portion 34 from splashing onto the indoor motor 222, reducing or avoiding the splashed condensed water from entering the coil of the stator 2221 through the gap between the rotor 2222 and the stator 2221, and thereby reducing or avoiding the condensed water from causing the indoor motor 222 to burn out after being powered on, thereby ensuring the normal operation and service life of the indoor motor 222.

[0100] In some embodiments, the fresh air volute 6 can be arranged on the side of the indoor fan 221 away from the indoor motor 222. The drainage portion 34 can be arranged on the side of the indoor motor 222 away from the indoor fan 221. In the embodiments of the present disclosure, the fresh air volute 6, the fresh air fan 7, and the fresh air motor 8 can be arranged to introduce outdoor fresh air into the indoor space. By arranging the fresh air volute 6 and the drainage portion 34 on the two sides of the indoor fan 221, the arrangement of the indoor unit of the air conditioner can be adapted, and interference between the installation of the fresh air volute 6 and the drainage portion 34 can be reduced or avoided.

[0101] In some embodiments, the main body 100 can further include a drain pipe (not shown in the figure), which can be connected to the base 3 and in communication with the drain hole 341 to drain the condensed water out of the drainage portion 34.

[0102] In some embodiments, referring to FIG. 10, the water pan 33 can include a first water pan 331. The first water pan 331 can be located on the front side of the volute tongue air duct 31 to store the condensed water and drain the condensed water out of the outdoor space.

[0103] In some embodiments, the first water pan 33 can be a groove to facilitate the accommodation of the condensed water and reduce or avoid the situation that the condensed water flows around in the machine housing 1.

[0104] In some embodiments, referring to FIG. 10, the base 3 can include a front volute tongue 351. Along the air flow path, the front volute tongue 351 is close to the indoor air inlet 111 and is a component part of the rear side wall of the first water pan 331.

[0105] In some embodiments, referring to FIG. 11, the indoor heat exchanger 21 can include a first section heat exchanger 211. The first section heat exchanger 211 can be located at the front bottom of the indoor heat exchanger 21. That is, the first section heat exchanger 211 can be located at the bottom of the indoor heat exchanger 21 and on the front side of the indoor fan 22. It should be noted that the front side of the indoor fan 22 refers to the side of the indoor fan 22 facing the user.

[0106] In some embodiments, referring to FIG. 11, the bottom end of the first section heat exchanger 211 can be located within the first water pan 331. The first water pan 331 can collect the condensed water flowing down from the first section heat exchanger 211.

[0107] In some embodiments, referring to FIG. 11, the indoor heat exchanger 21 can include a second section heat exchanger 212. The bottom end of the second section heat exchanger 212 can be connected to the top end of the first section heat exchanger 211.

[0108] In some embodiments, referring to FIG. 11, the second section heat exchanger 212 can be inclined. In the front-rear direction of the main body 100, the top end of the second section heat exchanger 212 can be located rearward of the bottom end of the second section heat exchanger 212, i.e., the top end of the second section heat exchanger 212 is located further away from the front side of the casing 1 than the bottom end of the second section heat exchanger 212.

[0109] In some embodiments, the bottom end of the second section heat exchanger 212 is located in front of the indoor fan 22, and the top end of the second section heat exchanger 212 is located above the indoor fan 22.

[0110] In some embodiments, the condensed water on the second section heat exchanger 212 can flow onto the first section heat exchanger 211, and then into the first water pan 331.

[0111] In some embodiments, referring to FIG. 10, the water pan 33 can include a second water pan 332. The second water pan 332 can be located at the rear side of the volute tongue air duct 31 to store the condensed water and discharge the condensed water outside through a drain pipe.

[0112] In some embodiments, in the length direction of the main body 100, one end of the second water pan 332 close to the drain portion 34 is located on the side of the drain portion 34 close to the indoor fan 221.

[0113] In some embodiments, the second water pan 332 can be a groove to accommodate the condensed water, so as to reduce or avoid the situation that the condensed water flows around in the casing 1.

[0114] In some embodiments, referring to FIG. 11, the indoor heat exchanger 21 can include a third section heat exchanger 213. The top end of the third section heat exchanger 213 can be connected to the top end of the second section heat exchanger 212. The third section heat exchanger 213 can be located rearward of the second section heat exchanger 212.

[0115] In some embodiments, referring to FIG. 11, the third section heat exchanger 213 can be inclined. In the front-rear direction of the main body 100, the top end of the third section heat exchanger 213 can be located forward of the bottom end of the third section heat exchanger 213.

[0116] In some embodiments, referring to FIG. 11, the bottom end of the third heat exchanger 213 can be located in the second water pan 332. In this way, the condensed water on the third heat exchanger 213 can flow into the second water pan 332.

[0117] In some embodiments, the indoor air inlet 111 can be located above the indoor heat exchanger 21. The indoor fan 221 can be located behind the first heat exchanger 211. The indoor fan 221 can be located below the top end of the second heat exchanger 212 and the third heat exchanger 213.

[0118] In some embodiments, referring to FIG. 10, the base 33 can include a rear volute tongue 352. Along the flow path of the air, the rear volute tongue 352 is close to the front side wall of the second water pan 332.

[0119] In some embodiments, referring to FIG. 9, the base 3 can be formed with a first flow guide part 361. The first flow guide part 361 can be located on the side of the indoor fan 221 away from the motor cavity 32.

[0120] In some embodiments, the first flow guide part 361 can include a first flow guide part side wall and a first flow guide part bottom wall. The drain part 34 can be a groove formed by the first flow guide part side wall and the first flow guide part bottom wall, so as to accommodate the condensed water and reduce or avoid the spread of the condensed water in the casing 1.

[0121] In some embodiments, along the length direction of the main body 100, the two ends of the first water pan 331 are in communication with the drain part 34 and the first flow guide part 361, respectively. In this way, the communication between the first water pan 331 and the drain part 34 can enable the condensed water collected by the first water pan 331 to flow into the drain part 34 and be discharged through the drain hole 341.

[0122] In some embodiments, along the length direction of the main body 100, the end of the second water pan 332 away from the drain part 34 is in communication with the first flow guide part 361, so as to enable the water in the second water pan 332 to flow into the first water pan 331 through the first flow guide part 361, and then flow into the drain part 34 through the first water pan 331, thereby ensuring that the water in the second water pan 332 can be smoothly discharged, reducing or avoiding the accumulation of condensed water in the second water pan 332, thereby reducing or avoiding the influence of mold and bacteria breeding on the health of users, in addition, it can also reduce or avoid the problem of air conditioner indoor unit water leakage and indoor air outlet 112 blowing water caused by the condensed water in the second water pan 332 being unable to be discharged, thereby improving the user experience and the market competitiveness of the air conditioner indoor unit of the present disclosure.

[0123] In some embodiments, referring to FIG. 12, a second flow guide 37 is formed on the base 3. The second flow guide 37 can be located on the rear side of the base 3 to receive condensed water on the base 3. Among them, referring to FIG. 14, one end of the second flow guide 37 can be in communication with the first flow guide 361, so that the water received by the second flow guide 37 can flow into the first water pan 331 through the first flow guide 361, and then flow into the drain 34 and be discharged through the drain hole 341. Along the length direction of the main body 100, the second flow guide 37 can be located on the side of the first flow guide 361 close to the drain 34. The end of the second flow guide 37 close to the first flow guide 361 is in communication with the first flow guide 361.

[0124] Among them, in order to facilitate drainage of the drain 34, the air conditioner indoor unit can be installed obliquely, so that one end of the drain 34 in the air conditioner indoor unit is set slightly lower, or due to the limitation of installation tools, it is easy to install obliquely. In order to facilitate drainage, the air conditioner indoor unit can be set to have one end of the drain 34 slightly lower, but this setting method will cause the water in the second water pan 332 to accumulate near the end of the drain 34 and cannot be discharged from the water pan 33.

[0125] Based on this, in some embodiments, referring to FIGS. 13 and 16, the second water pan 332 is provided with a first through hole 3321 for discharging water in the second water pan 332 from the second water pan 332. The first through hole 3321 can be provided on the bottom wall of the second water pan 332. The first through hole 3321 can be located at the end of the second water pan 332 close to the drain 34. Among them, when the first through hole 3321 is provided on the bottom wall of the second water pan 332, in the length direction of the main body 300, the first through hole 3321 is located on the side of the drain 34 close to the indoor fan 221.

[0126] Continuing to refer to FIG. 13, the second flow guide 37 can be provided below the first through hole 3321 to receive water flowing out of the first through hole 3321. The condensed water in the second water pan 332 can flow to the second flow guide 37 through the first through hole 3321, and then the condensed water flows into the first water pan 331 through the first flow guide 361, and then the condensed water flows into the drain 34 and is discharged through the drain hole 341.

[0127] In the present disclosure, the first through hole 3321 is arranged at the end of the second water pan 332 close to the drain part 34, so that when the air conditioner indoor unit is arranged to be inclined and the end of the air conditioner indoor unit where the drain part 34 is arranged is slightly lower, the condensed water accumulated in the second water pan 332 close to the end of the drain part 34 can be discharged from the second water pan 332 through the first through hole 3321, reducing or avoiding the accumulation of condensed water in the second water pan 332. At the same time, the direct arrangement of the channel between the second water pan 332 and the drain part 34 for communication can be reduced. Since the arrangement of the channel is reduced, the notch space 363 on the base 3 for the refrigerant inlet and outlet pipe of the indoor heat exchanger 21 can be reduced, thereby improving the problem of increasing the overall size of the main body 100 caused by the notch space.

[0128] In some embodiments, the maximum diameter of the indoor motor 222 with the motor rotating shaft is about 90 mm. The diameter of the outer rotor motor is greater than 100 mm. When the diameter of the indoor motor 222 with the motor rotating shaft is large, or the indoor motor 222 arranged is an outer rotor motor, due to the large diameter of the indoor motor 222, it is basically impossible to directly arrange a channel between the second water pan 332 and the drain part 34 for connection. If a channel is directly arranged, the size of the main body 100 in the front-rear and up-down directions will be increased. Therefore, in order to reduce the size of the main body 100 in the up-down and front-rear directions, some embodiments of the present disclosure can arrange a first through hole 3321 at the end of the second water pan 332 close to the drain part 34. The condensed water in the second water pan 332 can be guided to the second flow guide part 37, the first flow guide part 361, and the first water pan 331, and then flow into the drain part 34. This can reduce the size of the main body 100 in the front-rear and up-down directions, reduce material costs, and have an attractive appearance.

[0129] In some embodiments, the thickness of the indoor motor 222 with the motor rotating shaft can be about 60 mm. The thickness of the outer rotor motor can be any value between 35 mm and 45 mm. For example, the thickness of the outer rotor motor can be 40 mm. Based on this, some embodiments of the present disclosure can arrange the indoor motor 222 as an outer rotor motor. Since the thickness of the outer rotor motor is relatively thin, space can be saved in the length direction of the main body 100. In this way, the drain part 34 can be arranged on the side of the motor cavity 32 away from the indoor fan 221, so that the space in the length direction of the main body 100 can be fully utilized, and the situation that the condensed water splashes onto the indoor motor 222 and damages the indoor motor 222 can be reduced or avoided.

[0130] In some embodiments, with reference to FIG. 15, the size of the drain part 34 in the length direction of the main body 100 can be a first length L1.

[0131] In some embodiments, the first length L1 is greater than or equal to a first parameter value. The first parameter value can be any value in a range of 8mm-12mm. For example, the first parameter value can be 10mm, i.e., L1≥10mm. This embodiment can reduce or avoid the width of the drainage portion 34 being too small, so that the opening of the connecting end of the water pan 33 is too small to affect the flow of condensate water from the water pan 33 into the drainage portion 34, and can ensure the drainage efficiency.

[0132] In some embodiments, the first length L1 is less than or equal to a second parameter value. The second parameter value can be any value in a range of 18mm-22mm. For example, the second parameter value can be 20mm, i.e., L1≤20mm. This embodiment can reduce or avoid the width of the drainage portion 34 being too large, so that the length of the main body 100 is large, and the waste of the length of the main body 100 is reduced.

[0133] In some embodiments, the second flow guide portion 37 is inclined relative to the length direction of the main body 100, and one end of the second flow guide portion 37 connected to the first flow guide portion 361 is the end of the second flow guide portion 37 close to the bottom end of the main body 100.

[0134] In some embodiments, referring to FIGS. 13-17, the angle between the extension direction of the second flow guide portion 37 and the length direction of the main body 100 can be a first angle α1. The third parameter value can be any value in a range of 1°-3°. The third parameter value can be 2°, i.e., α1≥2°. By setting α1≥2°, a sufficient first angle is ensured, which can facilitate the flow of condensate water in the second flow guide portion 37 to the first flow guide portion 361 when the main body 100 is installed horizontally, thereby facilitating the flow of condensate water to the drainage portion 34 and out of the drainage portion 34.

[0135] In some embodiments, when the air conditioner indoor unit is tilted and one end of the drainage portion 34 is slightly lower, due to the size of the length of the air conditioner indoor unit, the angle of the tilt of the air conditioner indoor unit cannot be too large in the case that the human eye can distinguish, and α1≥2° is set. When the main body 100 is tilted relative to the horizontal plane and the second water pan 332 has one end of the drainage portion 34 as the bottom end, the height of the second flow guide portion 37 close to one end of the first flow guide portion 361 can not exceed the height of the second flow guide portion 37 away from one end of the first flow guide portion 361, so that the condensed water in the second flow guide portion 37 flows into the first flow guide portion 361, thereby facilitating the flow of condensed water to the drainage portion 34 and out of the drainage portion 34, solving the problem of difficult drainage of condensed water at the second water pan 332 and the second flow guide portion 37 caused by setting one end of the drainage portion 34 slightly lower, i.e., reducing or avoiding the accumulation of condensed water in the second water pan 332 and the second flow guide portion 37, thereby reducing or avoiding the problem of mold and bacteria affecting the health of users, in addition, it can also reduce or avoid the problem of water in the second water pan 332 being unable to drain, causing the air conditioner indoor unit to leak and the indoor air outlet 112 to blow water, thereby improving user experience and market competitiveness.

[0136] In some embodiments, when the main body 100 is tilted relative to the horizontal plane and the second water pan 332 has one end of the drainage portion 34 as the bottom end, the water in the first water pan 331 and the first flow guide portion 361 can be easily drained into the drainage portion 34, and the drain hole 341 is at the lowest point of the drainage portion 34, facilitating the drainage of water in the drainage portion 34.

[0137] In some embodiments, referring to FIGS. 18 and 19, the second flow guide portion 37 has one end away from the first flow guide portion 361, and the distance between the second flow guide portion 37 and the closest point of the bottom end of the main body 100 is the first point. The second flow guide portion 37 has one end connected to the first flow guide portion 361, and the distance between the second flow guide portion 37 and the closest point of the bottom end of the main body 100 is the second point. In the height direction of the main body 100, the height difference between the first point and the second point is the first height difference H. In the length direction of the main body 100, the length of the second flow guide portion 37 is L2. H / L2=tanα1.

[0138] In some embodiments, H / L2≥the tenth parameter value. The tenth parameter value can be any value between 0.017 and 0.053. The tenth parameter value can be 0.034, i.e., H / L2≥0.034, to ensure that the second flow guide portion 37 has a large tilt relative to the length direction of the main body 100, thereby improving the situation that when the main body 100 is tilted, the end of the second flow guide portion 37 close to the first flow guide portion 361 is too high, causing the water in the second flow guide portion 37 to be unable to enter the first flow guide portion 361, and making it difficult to drain the condensed water in the second flow guide portion 37.

[0139] In some embodiments, H is greater than or equal to a fourth parameter value. The fourth parameter value can be any value in the range of 12mm-20mm. The fourth parameter value can be 17mm, i.e., H is greater than or equal to 17mm, which can improve the situation that H is too small to make a1 too small, thereby ensuring that the second flow guide portion 37 has a large inclination relative to the length direction of the main body 100, and improving the situation that when the main body 100 is inclined, the end of the second flow guide portion 37 close to the first flow guide portion 361 is too high to cause the condensed water in the second flow guide portion 37 to be unable to enter the first flow guide portion 361, making it difficult to drain the condensed water in the second flow guide portion 37. Such design can also improve the situation that the size of H is too small to make the inclination height of the indoor unit corresponding to a1 not obvious, and by limiting the inclination angle of the air conditioner indoor unit to within 2°, the function of the second flow guide portion 37 to guide the condensed water into the first flow guide portion 361 is ensured.

[0140] In some embodiments, L2 can be any value in the range of 500mm-800mm. For example, L2 can be 640mm. When L2 is 640mm, the minimum value of H can be 23mm.

[0141] In some embodiments, in the length direction of the main body 100, the length of the volute tongue air duct 31 can be any value in the range of 500mm-800mm.

[0142] In some embodiments, in the length direction of the main body 100, the length of the volute tongue air duct 31 can be equal to the length of the second flow guide portion 37, which can make full use of the volute tongue air duct to guide the air flow generated by the fan and increase the air volume.

[0143] In some embodiments, referring to FIG. 19, the base 3 can include a base body 301. The base 3 can include a second flow guide plate 302. The second flow guide plate 302 is connected to the rear side of the base body 301. The second flow guide plate 302 and the base body 301 form the second flow guide portion 37.

[0144] In some embodiments, referring to FIGS. 19 and 20, the bottom end of the second flow guide plate 302 is connected to the base body 301. In the front-rear direction of the main body 100, the top end of the second flow guide plate 302 is located behind the bottom end of the second flow guide plate 302, so that the second flow guide plate 302 and the base body 301 can form the second flow guide portion 37 that can hold water.

[0145] In some embodiments, the first water pan 331 can be in communication with the drain portion 34, and the condensed water in the first water pan 331 can flow into the drain portion 34. The second water pan 332 can be in communication with the drain portion 34 at an end of the second water pan 332 close to the drain portion 34, and the water in the second water pan 332 can flow into the drain portion 34 through the end of the second water pan 332 close to the drain portion 34. The bottom wall of the drain portion 34 can be provided with a drain hole 341. The drain hole 341 is configured to drain water. The drain hole 341 can drain the condensed water in the drain portion 34.

[0146] In this embodiment, by setting the end of the second water pan 332 close to the drain portion 34 in communication with the drain portion 34, the condensed water in the second water pan 332 can flow into the drain portion 34 through the end of the second water pan 332 close to the drain portion 34. This design can reduce the length of the drain path, reduce or avoid the overflow of the local position during the drainage process, and can reduce the amount of water in the second water pan 332 drained into the first water pan 331, reduce the drainage pressure of the first water pan 331, and improve or avoid the overflow of the first water pan 331.

[0147] In some embodiments, referring to FIGS. 21 and 22, the main body 100 can include a first communication portion 362. The first communication portion 362 can be formed on the base 3. The first communication portion 362 can be located behind the drain portion 34. The first communication portion 362 can be a communication channel. The first communication portion 362 can be in communication with the drain portion 34. Referring to FIG. 23, the front side bottom end of the first communication portion 362 can be in communication with the rear side of the drain portion 34.

[0148] In some embodiments, referring to FIG. 23, the end of the second water pan 332 close to the drain portion 34 can be in communication with the first communication portion 362. The end of the second water pan 332 close to the drain portion 34 can be in communication with the drain portion 34 through the first communication portion 362, and the condensed water in the second water pan 332 can flow into the drain portion 34 through the first communication portion 362.

[0149] In this embodiment, the first communication portion 362 is provided to directly communicate the second water pan 332 and the drain portion 34, to reduce the length of the drain path of the second water pan 332 and reduce the drainage pressure of the first water pan 331.

[0150] In some embodiments, referring to FIG. 24, the first flow guide portion 361 is formed on the base 3. The first flow guide portion 361 can be arranged on the side of the indoor fan 221 away from the motor cavity 32. The first water pan 331 can be in communication with the drain portion 34 and the first flow guide portion 361 at both ends of the main body 100 in the length direction, respectively. In the length direction of the main body 100, the second water pan 332 can be in communication with the first flow guide portion 361 at the end away from the drain portion 34, so that the condensed water in the second water pan 332 can flow into the first water pan 331 through the first flow guide portion 361, and then flow into the drain portion 34 through the first water pan 331.

[0151] In some embodiments, the base 3 is provided with a gap space 363 for the indoor heat exchanger 21 refrigerant inlet and outlet pipe to pass through. In the embodiment of the present disclosure, the first communication portion 362 is arranged to reduce the possibility of overflow of the first water pan 331 caused by the second water pan 332 winding around the second flow guide portion 37, the first flow guide portion 361 and the first water pan 331, and then being drained to the drain portion 34, thereby improving the user experience.

[0152] In some embodiments, referring to FIGS. 21-24, the second flow guide portion 37 is formed on the base 3. The second flow guide portion 37 can be located on the rear side of the base 3 to receive the condensed water on the base 3.

[0153] In some embodiments, in the length direction of the main body 100, the second flow guide portion 37 can be located on the side of the first flow guide portion 361 close to the drain portion 34, and one end of the second flow guide portion 37 can be in communication with the first flow guide portion 361, so that the water received by the second flow guide portion 37 can flow into the first water pan 331 through the first flow guide portion 361, and then flow into the drain portion 34 and be discharged through the drain hole 341.

[0154] In some embodiments, the second flow guide portion 37 is arranged obliquely relative to the length direction of the main body 100, and the end of the second flow guide portion 37 connected to the first flow guide portion 361 is the end of the second flow guide portion 37 close to the bottom end of the main body.

[0155] In some embodiments, referring to FIGS. 21-24, the second flow guide 37 has an angle a1 with the length direction of the main body 100. The angle a1 is greater than or equal to a third parameter value. The third parameter value can be any value between 1° and 3°. The third parameter value can be 2°, i.e., a1 > 2°. By setting a1 > 2°, the first angle is small enough to facilitate the water flow in the second flow guide 37 to the first flow guide 361 when the main body 100 is installed horizontally, and to facilitate the water flow to the drain 34 and out of the drain 34. By setting a1 > 2°, when the main body 100 is inclined relative to the horizontal plane and the second water receiving tray 332 has a bottom end at the end close to the drain 34, the end of the second flow guide 37 close to the first flow guide 361 is not more than the end of the second flow guide 37 away from the first flow guide 361, so that the condensed water in the second flow guide 37 can flow to the first flow guide 361, facilitating the condensed water to flow to the drain 34 and out of the drain 34, solving the problem of difficult drainage of water in the second flow guide 37 caused by the slightly lower end of the drain 34, reducing or avoiding the accumulation of condensed water in the second flow guide 37, thereby reducing or avoiding mold and bacteria growth affecting the health of the user.

[0156] In some embodiments, along the length direction of the main body 100, the second flow guide 37 is located on the side of the first flow guide 361 close to the drain 34. Along the length direction of the main body 100, the two ends of the second flow guide 37 are in communication with the first communication part 362 and the first flow guide 361, respectively, facilitating the water in the second flow guide 37 to flow from both ends to the drain 34, and increasing the drainage efficiency of the second flow guide 37.

[0157] In some embodiments, referring to FIGS. 25 and 26, the side wall of the first communication part 362 can be provided with a second through hole 3621, and the second flow guide 37 and the first communication part 362 can be in communication through the second through hole 3621, facilitating the communication between the first communication part 362 and the second flow guide 37.

[0158] In some embodiments, along the length direction of the main body 100, the two ends of the second flow guide 37 can be lower than the middle part of the second flow guide 37, so that the water in the second flow guide 37 can flow to the first communication part 362 and the first flow guide 361, respectively.

[0159] In some embodiments, referring to FIG. 3, the second flow guide 37 can include a first sub-flow guide 371. The first sub-flow guide 371 can be located at the end of the second flow guide 37 close to the first communication part 362.

[0160] In some embodiments, referring to FIG. 30, the second flow guide 37 includes a second sub-flow guide 372. The second sub-flow guide 372 can be located at one end of the second flow guide 37 close to the first flow guide 361. Wherein, the adjacent ends of the first sub-flow guide 371 and the second sub-flow guide 372 are connected.

[0161] In some embodiments, the first sub-flow guide 371 and the second sub-flow guide 372 are inclined relative to the length direction of the main body 100. The end of the first sub-flow guide 371 connected to the second sub-flow guide 372 is the end of the first sub-flow guide 371 away from the bottom end of the main body 100. The end of the second sub-flow guide 372 connected to the first sub-flow guide 371 is the end of the second sub-flow guide 372 away from the bottom end of the main body 100.

[0162] In the present disclosure, by setting the first sub-flow guide 371 and the second sub-flow guide 372 to be inclined relative to the length direction of the main body, the condensed water on the first sub-flow guide 371 and the second sub-flow guide 372 can be respectively guided to the first communication part 362 and the first flow guide 361.

[0163] In some embodiments, the angle between the extension direction of the first sub-flow guide 371 and the length direction of the main body 100 is a second angle a2. Wherein, a2≥ the fourth parameter value. The fourth parameter value can be any value between 1°-3°. The fourth parameter value can be 2°, that is: a2≥ 2°, which can ensure that there is a sufficient second angle, so that when the main body 100 is installed horizontally or the main body 100 is inclined relative to the horizontal plane, the end of the first sub-flow guide 371 close to the first communication part 362 does not exceed the end of the first sub-flow guide 371 away from the first communication part 362, and the condensed water in the first sub-flow guide 371 can flow into the first communication part 362, facilitating the flow of condensed water to the drain 34 and out of the drain 34.

[0164] In some embodiments, the angle between the extension direction of the second sub-flow guide 372 and the length direction of the main body 100 is a third angle a3. Wherein, a3≥ the fifth parameter value. The fifth parameter value can be any value between 1°-3°. The fifth parameter value can be 2°, that is: a3≥ 2°, which can ensure that there is a sufficient third angle, so that when the main body 100 is installed horizontally or the main body 100 is inclined relative to the horizontal plane, the end of the second sub-flow guide 372 close to the first flow guide 361 does not exceed the end of the second sub-flow guide 372 away from the first flow guide 361, and the water in the second sub-flow guide 372 can flow into the first flow guide 361, facilitating the flow of water to the drain 34 and out of the drain 34.

[0165] In some embodiments, the second flow guide 37 can be horizontally arranged, so that no matter how the length direction of the main body 100 is inclined relative to the horizontal plane, water can flow into the drain 34.

The first height h1≥ the seventh parameter value. The seventh parameter value can be any value in the range of 5mm-7mm. For example, the seventh parameter value can be 5mm, i.e., the first height h1≥5mm, which can ensure a sufficient first height to keep a certain distance between the indoor motor 222 and the motor cavity 32 lowest point, thereby improving the situation that the indoor motor 222 is easily damaged by contacting water when there is water in the motor cavity 32.

[0209] In some embodiments, referring to FIGS. 43 and 44, in the vertical direction, the overflow height of the overflow groove gap 368 relative to the motor cavity 32 lowest point is a second height h2. The second height h2≥ the eighth parameter value. The eighth parameter value can be any value in the range of 0mm-2mm. For example, the eighth parameter value can be 0mm, i.e., the second height h2≥0mm, which can make the lower limit value of the second height as small as possible, facilitating the water in the motor cavity 32 to flow into the fourth through hole 3681 and / or through the overflow groove gap 368 to flow into the volute air duct 31.

[0210] In some embodiments, h1>h2, which can reduce or prevent water in the motor cavity 32 from contacting the indoor motor 222 before reaching the overflow height, thereby reducing or preventing the indoor motor 222 from being affected by water.

Wherein, the fourth distance L4 ≤ the ninth parameter value. The ninth parameter value can be any value between 8mm and 12mm. For example, the ninth parameter value can be 10mm, that is, the fourth distance L4 ≤ 10mm, to improve or avoid excessive offset of the connection point of the first rear wall 33121 and the second rear wall 33122 towards the volute duct 31, avoiding excessive height of the front volute 351 and abnormal noise from the volute duct 31.

[0213] In some embodiments, the wall surface of the first water-blocking rib 365 on the side away from the second water-blocking rib 366 can be coplanar with the first end face 353 of the volute duct to divert condensate and reduce the overflow of condensate.

[0214] In some embodiments, the wall surface of the first water-blocking rib 365 away from the second water-blocking rib 366 may be located on the side of the first end face 353 of the volute air duct near the motor cavity 32.
