[0159] The bottom end of the first section heat exchanger can be located in the first water receiving pan. The first water receiving pan can receive condensed water flowing down from the first section heat exchanger.

[0160] In this application, reference is made to Figure 9-11 , the indoor heat exchanger may include a second stage heat exchanger 212. The bottom end of the second stage heat exchanger may be connected to the top end of the first stage heat exchanger.

[0161] In the present application, the second section heat exchanger can be arranged tilted. In the front-to-back direction of the main body, the top end of the second section heat exchanger can be located behind the bottom end of the second section heat exchanger.

[0162] In the present application, the condensed water on the second stage heat exchanger can flow to the first stage heat exchanger and then flow into the first water receiving pan.

[0163] In this application, reference is made to Figure 9-11 The water receiving tray may include a second water receiving tray 332. The second water receiving tray 332 may be located at the rear side of the volute tongue air duct.

[0164] In the present application, in the length direction of the main body, one end of the second water receiving pan close to the drainage portion is located on a side of the drainage portion close to the indoor fan.

[0165] In the present application, the second water receiving tray may be a trough body.

[0166] In this application, reference is made to Figure 9-11 The indoor heat exchanger may include a third section heat exchanger 213. The top end of the third section heat exchanger may be connected to the top end of the second section heat exchanger. The third section heat exchanger may be located behind the second section heat exchanger.

[0167] In the present application, the third section heat exchanger can be arranged tilted. In the front-to-back direction of the main body, the top end of the third section heat exchanger can be located in front of the bottom end of the third section heat exchanger.

[0168] In the present application, the bottom end of the third stage heat exchanger may be located in the second water receiving tray.

[0169] In the present application, the condensed water on the third stage heat exchanger can flow into the second water receiving pan.

[0170] In the present application, the indoor air inlet may be located above the indoor heat exchanger.

[0171] In the present application, the indoor fan can be located behind the first stage heat exchanger. The indoor fan can be located below the top of the second stage heat exchanger and the third stage heat exchanger.

[0172] In this application, reference is made to Figure 9-11 The base 3 may include a rear volute tongue 352. Along the air flow path, a section of the rear volute tongue 352 close to the indoor air inlet is a component of the front side wall of the second water receiving tray.

[0173] In this application, reference is made to Figure 9-11 A first air guide portion 361 may be formed on the base. The first air guide portion may be located on a side of the indoor fan away from the motor cavity.

[0174] In the present application, the first guide portion may include a first guide portion side wall. The first guide portion may include a first guide portion bottom wall. The drainage portion may be a trough body surrounded by the first guide portion side wall and the first guide portion bottom wall.

[0175] In the present application, along the length direction of the main body, two ends of the first water receiving tray are respectively connected to the drainage part and the first guide part.

[0176] The first water receiving pan is connected to the drainage portion, so that the condensed water received by the first water receiving pan can flow into the drainage portion and be discharged through the drainage hole.

[0177] In the present application, along the length direction of the main body, one end of the second water receiving pan away from the drainage part is connected to the first guide part. The water in the second water receiving pan can flow into the first water receiving pan through the first guide part, and then flow into the drainage part through the first water receiving pan, ensuring that the water in the second water receiving pan can be drained, avoiding water accumulation in the second water receiving pan, avoiding mold and breeding bacteria that affect the health of users, and avoiding the water in the second water receiving pan from being unable to be drained, causing water leakage in the air conditioner indoor unit and water blowing from the indoor air outlet, avoiding affecting the user experience, and avoiding reducing the market competitiveness of the air conditioner indoor unit.

[0178] In this application, reference is made to Fig.12 A second guide portion 37 is formed on the base. The second guide portion 37 can be located at the rear side of the base to receive condensed water on the base.

[0179] In the present application, one end of the second guide part can be connected to the first guide part, so that the water received by the second guide part can flow into the first water receiving tray through the first guide part, and then flow into the drainage part and be discharged through the drainage hole.

[0180] In the present application, along the length direction of the main body, the second guide portion is located on a side of the first guide portion close to the drainage portion. One end of the second guide portion close to the first guide portion is connected to the first guide portion.

[0181] Generally, the air-conditioning indoor unit is installed horizontally. In order to facilitate drainage of the drain part, the air-conditioning indoor unit is installed at an angle. One end of the drain part of the air-conditioning indoor unit can be set slightly lower, or it can be installed at an angle due to limited installation tools. In order to facilitate drainage, one end of the drain part of the air-conditioning indoor unit is usually set slightly lower. However, this arrangement will cause the water in the second water receiving tray to accumulate at one end close to the drain part and cannot be discharged from the water receiving tray.

[0182] In this application, reference is made to Figure 13-Figure 17 The second water receiving tray is provided with a first through hole 3321 for discharging water in the second water receiving tray out of the second water receiving tray.

[0183] In this application, reference is made to Figure 13-Figure 17 The first through hole 3321 can be provided on the bottom wall of the second water receiving tray. The first through hole 3321 can be located at one end of the second water receiving tray close to the drainage portion.

[0184] In the present application, when the bottom wall of the second water receiving tray is provided with a first through hole, in the length direction of the main body, the first through hole is located on a side of the drainage portion close to the indoor fan.

[0185] In this application, reference is made to Figure 13-Figure 17 The second guide part 37 can be arranged below the first through hole 3321 to receive the water flowing out of the first through hole. The water in the second water receiving tray can flow to the second guide part through the first through hole, and then the water flows into the first water receiving tray through the first guide part, and then the water flows into the drainage part and is discharged through the drainage hole.

[0186] In the present application, a first through hole is provided at one end of the second water receiving pan near the drainage part, so that when the air conditioner indoor unit is tilted and one end of the air conditioner indoor unit with the drainage part is slightly lower, the water accumulated at one end of the second water receiving pan near the drainage part can be discharged from the second water receiving pan through the first through hole, thereby avoiding water accumulation in the second water receiving pan. In addition, it is possible to avoid directly providing a channel connection between the second water receiving pan and the drainage part, avoid the provided channel occupying the gap space 363 provided on the base for the refrigerant inlet and outlet pipes of the indoor heat exchanger, and avoid the increase in the overall size of the main body caused by occupying the gap space.

[0187] In this application, the maximum diameter of the original indoor motor with the motor rotating shaft is generally about 90 mm. The diameter of the outer rotor motor is generally greater than 100 mm.

[0188] When the diameter of the indoor motor with a motor rotating shaft is large, or the indoor motor is an outer rotor motor, due to the large diameter of the indoor motor, it is impossible to directly set a channel connection between the second water receiving tray and the drainage part. When the channel is directly set, the dimensions of the main body in the front-to-back and up-to-down directions will increase. When avoiding increasing the up-to-down and front-to-back dimensions of the main body, a first through hole is set at one end of the second water receiving tray close to the drainage part, so that the water in the second water receiving tray can flow around the second guide part, the first guide part and the first water receiving tray, and then flow into the drainage part, which can reduce the front-to-back and up-to-down dimensions of the main body, reduce material costs, and have a beautiful appearance.

[0189] In the present application, the thickness of the original indoor motor with the motor rotating shaft is generally about 60 mm. The thickness of the outer rotor motor is any value between 35 mm and 45 mm. The thickness of the outer rotor motor can be 40 mm. Therefore, setting the indoor motor as an outer rotor motor can save space in the length direction of the main body. Therefore, the drainage part can be set on the side of the motor cavity away from the indoor fan, which can fully utilize the space in the length direction of the main body and avoid water splashing onto the indoor motor to cause damage to the indoor motor.

[0190] In this application, reference is made to Figure 13-Figure 17 , the dimension of the drainage portion in the length direction of the main body can be a first length L1.

[0191] In the present application, the first length L1 ≥ the first parameter value. The first parameter value may be any value between 8 mm and 12 mm. The first parameter value may be 10 mm. L1 ≥ 10 mm. Avoiding the width of the drainage portion being too small, so that the opening of the connection end between the drainage portion and the water receiving tray is too small to affect the water from the water receiving tray into the drainage portion, can ensure drainage efficiency.

[0192] In the present application, the first length L1≤the second parameter value. The second parameter value may be any value between 18 mm and 22 mm. The second parameter value may be 20 mm. L1≤20 mm. Avoid the width of the drainage portion being too large so as to make the length dimension of the main body larger, and avoid wasting the length dimension of the main body.

[0193] In the present application, the second guide portion is arranged obliquely relative to the length direction of the main body, and the end of the second guide portion connected to the first guide portion is the end of the second guide portion close to the bottom end of the main body.

[0194] In this application, reference is made to Figure 13-Figure 17 The included angle between the extension direction of the second guide portion and the length direction of the main body is a first angle α1.

[0195] In the present application, α1≥the third parameter value. The third parameter value may be any value between 1° and 3°. The third parameter value may be 2°. α1≥2°.

[0196] Set α1≥2° to avoid the first angle being too small, so that when the main body is installed horizontally, it is convenient for water in the second guide part to flow into the first guide part, and it is convenient for the water to flow to the drainage part and be discharged from the drainage part.

[0197] When the air-conditioning indoor unit is tilted and one end of the drainage part is slightly lower, due to the length of the air-conditioning indoor unit, the tilt angle of the air-conditioning indoor unit will not be very large when it can be distinguished by the human eye. By setting α1≥2°, when the main body is tilted relative to the horizontal plane and the end of the second water receiving pan close to the drainage part is the bottom end, the height of the end of the second guide part close to the first guide part does not exceed the end of the second guide part far from the first guide part, so that water in the second guide part can flow into the first guide part, which facilitates the water to flow to the drainage part and discharge the drainage part, solves the problem of water in the second water receiving pan and the second guide part being difficult to drain due to one end of the drainage part being slightly lower, avoids water accumulation in the second water receiving pan and the second guide part, avoids mold and bacteria breeding that affect the health of users, and avoids the problem that the water in the second water receiving pan cannot be drained out, causing water leakage in the air-conditioning indoor unit and water blowing out of the indoor air outlet, avoids affecting the user experience, and avoids reducing the market competitiveness of the air-conditioning indoor unit.

[0198] In the present application, when the main body is inclined relative to the horizontal plane and the end of the second water receiving tray close to the drainage part is the bottom end, the water in the first water receiving tray and the first guide part can be easily discharged into the drainage part, and the drainage hole is at the lowest point of the drainage part, which is convenient for the drainage of water in the drainage part.

[0199] In this application, reference is made to Figure 18-Figure 19 The point at which the end of the second guide part away from the first guide part is closest to the bottom of the main body is the first point D1. The point at which the end of the second guide part connected to the first guide part is closest to the bottom of the main body is the second point D2.

[0200] In the height direction of the main body, the height difference between the first point and the second point is a first height difference H. In the length direction of the main body, the length of the second air guide portion is L2. H / L2=tanα1.

[0201] In the present application, H / L2≥10th parameter value. The 10th parameter value can be any value between 0.017-0.053. The 10th parameter value can be 0.034. H / L2≥0.034 avoids the second guide part from being tilted too small relative to the length direction of the main body, avoids the end of the second guide part close to the first guide part being too high when the main body is tilted, resulting in the water in the second guide part being unable to enter the first guide part, and avoids making it difficult to discharge the water in the second guide part.

[0202] In the present application, H≥the fourth parameter value. The fourth parameter value can be any value between 12mm-20mm. The fourth parameter value can be 17mm. H≥17mm. Avoid H being too small so that α1 is too small, avoid the second guide part being tilted too small relative to the length direction of the main body, avoid the end of the second guide part close to the first guide part being too high when the main body is tilted, resulting in the water in the second guide part being unable to enter the first guide part, and avoid making the water in the second guide part difficult to drain. And avoid the size of H being too small so that the tilt height of the indoor unit corresponding to α1 is not obvious, and the tilt angle of the air-conditioning indoor unit can be limited to within 2° to ensure that the second guide part can guide water into the first guide part.

[0203] In the present application, L2 may be any value between 500 mm and 800 mm.

[0204] In this application, L2 may be 640 mm.

[0205] In the present application, when L2 is 640 mm, the minimum value of H can be 23 mm.

[0206] In the present application, in the length direction of the main body, the length of the volute tongue air duct can be any value between 500mm and 800mm.

[0207] In the present application, in the length direction of the main body, the length of the volute tongue air duct may be equal to the length of the second air guide portion.

[0208] In this application, reference is made to Figure 18-Figure 20 The base includes a base body 301. The base may include a second guide plate 302. The second guide plate is connected to the rear side of the base body. The second guide plate and the base body form a second guide portion.

[0209] In the present application, the bottom end of the second guide plate 302 is connected to the base body. Along the front-to-back direction of the main body, the top end of the second guide plate is located behind the bottom end of the second guide plate, so that the second guide plate and the base body can form a second guide part that can receive water.

[0210] In the present application, the first water receiving tray may be in communication with the drainage portion, and the water in the first water receiving tray may flow into the drainage portion.

[0211] In the present application, one end of the second water receiving tray close to the drainage portion may be in communication with the drainage portion, and the water in the second water receiving tray may flow into the drainage portion through the one end of the second water receiving tray close to the drainage portion.

[0212] In the present application, a drainage hole may be provided on the bottom wall of the drainage portion. The drainage hole 341 is used for drainage. The drainage hole can drain water in the drainage portion.

[0213] Arranging an end of the second water receiving pan close to the drainage portion to be connected to the drainage portion can allow water in the second water receiving pan to flow into the drainage portion through the end of the second water receiving pan close to the drainage portion, thereby reducing the length of the drainage path and avoiding water overflow at a local location during the drainage process. It can also reduce the amount of water discharged from the second water receiving pan into the first water receiving pan, thereby reducing the drainage pressure of the first water receiving pan and avoiding overflow at the first water receiving pan.

[0214] In this application, reference is made to Figure 21-23 The main body may include a first communication portion 362. The first communication portion 362 may be formed on the base. The first communication portion may be located behind the drainage portion.

[0215] In the present application, the first connecting portion may be a connecting channel.

[0216] In the present application, the first communication portion may be in communication with the drainage portion. The front bottom end of the first communication portion may be in communication with the rear side of the drainage portion.

[0217] In the present application, one end of the second water receiving tray near the drain portion can be connected to the first connecting portion. One end of the second water receiving tray near the drain portion can be connected to the drain portion through the first connecting portion, and the water in the second water receiving tray can flow into the drain portion through the first connecting portion.

[0218] The first connecting portion can directly connect the second water receiving tray and the drainage portion, thereby reducing the drainage path length of the second drainage tray and reducing the drainage pressure of the first water receiving tray.

[0219] In this application, reference is made to Figure 21-24 A first air guide 361 is formed on the base. The first air guide can be arranged on a side of the indoor fan away from the motor cavity.

[0220] In the present application, two ends of the first water receiving tray along the length direction of the main body can be connected to the drainage part and the first guide part respectively.

[0221] In the present application, in the length direction of the main body, one end of the second water receiving tray away from the drainage portion may be in communication with the first guide portion.

[0222] The water in the second water receiving tray can flow into the first water receiving tray through the first guide portion, and then flow into the drainage portion through the first water receiving tray.

[0223] In the present application, a gap space 363 is provided on the base for the refrigerant inlet and outlet pipes of the indoor heat exchanger to pass through. The provision of the first connecting portion reduces the size of the gap space, and the reduction of the gap space is likely to increase the overall size of the main body, but reduces the possibility of the first water receiving pan overflowing due to the second water receiving pan winding around the second guide part, the first guide part and the first water receiving pan and then draining to the drainage part, thereby improving the user experience.

[0224] In this application, reference is made to Figure 21-24 A second guide portion 37 is formed on the base. The second guide portion 37 can be located at the rear side of the base to receive condensed water on the base.

[0225] In the present application, along the length direction of the main body, the second guide portion can be located on the side of the first guide portion close to the drainage portion, and one end of the second guide portion can be connected to the first guide portion, so that the water received by the second guide portion can flow into the first water receiving tray through the first guide portion, and then flow into the drainage portion and be discharged through the drainage hole.

[0226] In the present application, the second guide portion is arranged obliquely relative to the length direction of the main body, and the end of the second guide portion connected to the first guide portion is the end of the second guide portion close to the bottom end of the main body.

[0227] In this application, reference is made to Figure 21-24 The included angle between the extension direction of the second guide portion and the length direction of the main body is a first angle α1.

[0228] In the present application, α1≥the third parameter value. The third parameter value may be any value between 1° and 3°. The third parameter value may be 2°. α1≥2°.

[0229] Set α1≥2° to avoid the first angle being too small, so that when the main body is installed horizontally, it is convenient for water in the second guide part to flow into the first guide part, and it is convenient for the water to flow to the drainage part and be discharged from the drainage part.

[0230] By setting α1≥2°, when the main body is inclined relative to the horizontal plane and the end of the second water receiving tray close to the drainage part is the bottom end, the end of the second drainage part close to the first drainage part does not exceed the end of the second drainage part far from the first drainage part, so that water in the second drainage part can flow into the first drainage part, making it convenient for the water to flow to the drainage part and be discharged from the drainage part, solving the problem of water in the second drainage part being difficult to drain due to setting one end of the drainage part slightly lower, avoiding water accumulation in the second drainage part, and avoiding mold and bacteria growth that affect the health of users.

[0231] In the present application, along the length direction of the main body, the second guide part is located on the side of the first guide part close to the drainage part. Along the length direction of the main body, the two ends of the second guide part are respectively connected with the first connecting part and the first guide part, so that the water in the second guide part can flow from the two ends to the drainage part, thereby increasing the drainage efficiency of the second guide part.

[0232] In this application, reference is made to Figure 25-26 A second through hole 3621 may be provided on the side wall of the first connecting portion, and the second guide portion and the first connecting portion may be connected through the second through hole, so as to facilitate the connection between the first connecting portion and the second guide portion.

[0233] In the present application, along the length direction of the main body, both ends of the second guide portion may be lower than the middle portion of the second guide portion, so that water in the second guide portion may flow to the first connecting portion and the first guide portion respectively.

[0234] In the present application, the second flow guiding portion may include a first sub-flow guiding portion 371. The first sub-flow guiding portion may be located at one end of the second flow guiding portion close to the first connecting portion.

[0235] In the present application, the second guide portion includes a second sub-guide portion 372. The first sub-guide portion may be located at one end of the second guide portion close to the first guide portion.

[0236] In the present application, adjacent ends of the first sub-guiding portion and the second sub-guiding portion are connected.

[0237] In the present application, the first sub-guiding part and the second sub-guiding part are arranged obliquely relative to the length direction of the main body. The end of the first sub-guiding part connected to the second sub-guiding part is the end of the first sub-guiding part away from the bottom end of the main body. The end of the second sub-guiding part connected to the first sub-guiding part is the end of the second sub-guiding part away from the bottom end of the main body.

[0238] The first sub-guiding portion and the second sub-guiding portion are both inclined relative to the length direction of the main body, so that water on the first sub-guiding portion and the second sub-guiding portion can be guided to the first connecting portion and the first guiding portion respectively.

[0239] In the present application, the included angle between the extension direction of the first sub-guiding portion and the length direction of the main body is the second angle α2.

[0240] In the present application, α2≥the fourth parameter value. The fourth parameter value may be any value between 1°-3°. The fourth parameter value may be 2°. α2≥2°. To avoid the second angle being too small, when the main body is installed horizontally or when the main body is tilted relative to the horizontal plane, the end of the first sub-guiding part close to the first connecting part can be made not to exceed the end of the first sub-guiding part away from the first connecting part, so that the water in the first sub-guiding part can flow into the first connecting part, making it convenient for the water to flow to the drainage part and be discharged from the drainage part.

[0241] In the present application, the included angle between the extension direction of the second sub-guiding portion and the length direction of the main body is a third angle α3.

[0242] In the present application, α3≥5th parameter value. The fifth parameter value may be any value between 1°-3°. The fifth parameter value may be 2°. α3≥2°. Avoid the third angle being too small, so that when the main body is installed horizontally or when the main body is tilted relative to the horizontal plane, the end of the second sub-guiding part close to the first guiding part does not exceed the end of the second sub-guiding part away from the first guiding part, and the water in the second sub-guiding part can flow into the first guiding part, so that the water can flow to the drainage part and be discharged from the drainage part conveniently.

[0243] In the present application, the second guide portion may be arranged horizontally, so that water can flow into the drainage portion regardless of how the length direction of the main body is inclined relative to the horizontal plane.

[0244] In the present application, the rear portion of the first air guide portion may be provided with an opening.

[0245] In this application, reference is made to Figure 27-Figure 29 The main body may include a drain portion. The drain portion may be formed on the base. The drain portion may be located below the motor cavity. The drain portion and the motor cavity are isolated by a first partition 364.

[0246] The drainage part can be connected to the first water receiving tray. A drainage hole 341 can be provided on the bottom wall of the drainage part. Water in the first water receiving tray is discharged through the drainage hole.

[0247] The drainage part is arranged below the motor cavity and is isolated from the motor cavity by the first partition. When water gathers in the drainage part, the condensed water in the drainage part will not flow to the indoor motor, so as to avoid water splashing onto the indoor motor and causing the indoor motor to burn out after being powered on, thereby ensuring the normal operation and life of the indoor motor.

[0248] In the present application, when the drainage part is located below the motor cavity and is isolated from the motor cavity by the first partition, the indoor motor can be an outer rotor motor. When the indoor motor is an outer rotor motor, the drainage part is arranged below the motor cavity and is isolated from the motor cavity by the first partition, so that when water gathers in the drainage part, the condensed water in the drainage part will not flow to the indoor motor, so as to avoid water splashing onto the indoor motor, and avoid splashing water entering the stator coil through the gap between the rotor and the stator, so as to avoid water causing the indoor motor to burn out after power is turned on, thereby ensuring the normal operation and life of the indoor motor.

[0249] In this application, reference is made to Figure 27-Figure 29 The bottom wall of the first water receiving tray may be provided with a third through hole 3311. The first water receiving tray may be connected to the drainage portion through the third through hole, so that the first water receiving tray and the drainage portion are directly connected.

[0251] In the present application, the main body includes a first air guide portion 361. The first air guide portion 361 may be formed on the base. The first air guide portion 361 may be disposed on a side of the indoor fan away from the motor cavity.

[0252] In the present application, along the length direction of the main body, one end of the first water receiving tray away from the drainage portion is connected to the first guide portion.

[0253] In the present application, along the length direction of the main body, one end of the second water receiving tray away from the drainage portion is connected to the first guide portion, so that the water in the second water receiving tray can flow through the first guide portion to the first water receiving tray and be discharged into the drainage portion.

[0254] In the present application, a second guide portion 37 is formed on the rear side of the base. The second guide portion 37 is used to receive condensed water on the base.

[0255] Along the length direction of the main body, the second guide part is located on one side of the first guide part close to the drainage part. One end of the second guide part close to the first guide part is connected to the first guide part, so that water on the second guide part can flow into the first guide part and then into the drainage part.

[0256] In this application, reference is made to Figure 32-Figure 33 A first through hole 3321 is provided on the bottom wall of the second water receiving tray for water to flow from the second water receiving tray to the rear of the base.

[0257] In the present application, the second guide portion is located below the first through hole to receive the water flowing out of the first through hole, and can guide the water to the second water receiving tray through the first through hole and can guide the water to the drainage portion through the second guide portion, so that when the air-conditioning room is tilted, the water in the second water receiving tray can be discharged normally.

[0258] In the present application, the first through hole can be located at one end of the second water receiving pan near the drainage part, so that when the air-conditioning indoor unit is tilted and one end of the drainage part of the air-conditioning indoor unit is slightly lower, the water accumulated in the second water receiving pan near the drainage part can be discharged from the second water receiving pan through the first through hole, thereby avoiding water accumulation in the second water receiving pan.

[0259] In this application, reference is made to Figure 30-Figure 31 and Figure 34-Figure 35 The drainage portion is located below the first through hole to receive water flowing out of the first through hole.

[0260] In the present application, one end of the second guide part away from the first guide part can be connected to the drainage part, so that water in the second guide part can flow to the drainage part from both ends, thereby increasing the drainage efficiency of the second guide part.

[0261] In this application, reference is made to Fig.30 When the end of the second guide portion away from the first guide portion is connected to the drainage portion, the second guide portion may include a first sub-guide portion 371. The first sub-guide portion may be located at an end of the second guide portion close to the drainage portion.

The first sub-guide portion may be located at an end of the second guide portion close to the first guide portion.

[0263] In the present application, adjacent ends of the first sub-guiding portion and the second sub-guiding portion are connected.

[0264] In the present application, the first sub-guiding part and the second sub-guiding part are arranged obliquely relative to the length direction of the main body. The end of the first sub-guiding part connected to the second sub-guiding part is the end of the first sub-guiding part away from the bottom end of the main body. The end of the second sub-guiding part connected to the first sub-guiding part is the end of the second sub-guiding part away from the bottom end of the main body.

[0265] The first sub-guiding part and the second sub-guiding part are both inclined relative to the length direction of the main body, so that water on the first sub-guiding part and the second sub-guiding part can be directed to the drainage part and the first guiding part respectively.

[0266] In this application, reference is made to Fig.30 The included angle between the extension direction of the first sub-guiding portion and the length direction of the main body is a second angle α2.

[0267] In the present application, α2≥the fourth parameter value. The fourth parameter value may be any value between 1°-3°. The fourth parameter value may be 2°. α2≥2°. To avoid the second angle being too small, when the main body is installed horizontally or when the main body is tilted relative to the horizontal plane, the end of the first sub-guiding part close to the drainage part does not exceed the end of the first sub-guiding part away from the drainage part, so that the water in the first sub-guiding part can flow into the drainage part, making it convenient for the water to flow to the drainage part and be discharged from the drainage part.

[0268] In this application, reference is made to Fig.30 The included angle between the extension direction of the second sub-guiding portion and the length direction of the main body is a third angle α3.

[0269] In the present application, α3≥5th parameter value. The fifth parameter value may be any value between 1°-3°. The fifth parameter value may be 2°. α3≥2°.

[0271] In the present application, when one end of the second guide part is away from the first guide part and isolated from the drainage part, the second guide part is inclined relative to the length direction of the main body, and the end of the second guide part connected to the first guide part is the end of the second guide part close to the bottom end of the main body, which is convenient for guiding water to the first guide part.

[0272] In the present application, when one end of the second guide portion away from the first guide portion is isolated from the drainage portion, the included angle between the extension direction of the second guide portion and the length direction of the main body is a first angle α1. α1≥2°.

[0273] Set α1≥2° to avoid the first angle being too small, so that when the main body is installed horizontally, it is convenient for water in the second guide part to flow into the first guide part, and it is convenient for the water to flow to the drainage part and be discharged from the drainage part.

[0274] By setting α1≥2°, when the main body is inclined relative to the horizontal plane and the end of the second water receiving tray close to the drainage part is the bottom end, the end of the second drainage part close to the first drainage part does not exceed the end of the second drainage part far from the first drainage part, so that water in the second drainage part can flow into the first drainage part, making it convenient for the water to flow to the drainage part and be discharged from the drainage part, solving the problem of water in the second drainage part being difficult to drain due to setting one end of the drainage part slightly lower, avoiding water accumulation in the second drainage part, and avoiding mold and bacteria growth that affect the health of users.

[0277] In the present application, the main body may include a first water receiving tray 331. The first water receiving tray may be formed on the base 3. The first water receiving tray may receive condensed water flowing down from the indoor heat exchanger.

[0278] In the present application, a water receiving tray may be formed on the base, and the water receiving tray is used to receive condensed water flowing down from the indoor heat exchanger. The water receiving tray may include a first water receiving tray.

[0279] In the present application, the indoor heat exchanger may include a first stage heat exchanger. The bottom end of the first stage heat exchanger may be located in a first water receiving pan. Condensed water on the first stage heat exchanger may flow on the first water receiving pan.

[0280] In the present application, the indoor heat exchanger may include a second-stage heat exchanger, and the condensed water on the second-stage heat exchanger may flow to the first water receiving pan.

[0281] In the present application, the first water receiving tray may be located in front of the volute tongue air duct. The first water receiving tray may be located in front of the motor cavity.

[0282] In this application, reference is made to Fig.36 The first water receiving tray may have a first water receiving tray rear wall 3312. The first water receiving tray rear wall may be located at the rear side of the first water receiving tray.

[0283] In the present application, the air conditioner indoor unit is limited by the fresh air module, and generally a drain hole and a drain pipe are set on one side of the air conditioner indoor unit. In addition, the air conditioner indoor unit is affected by its overall structure, and generally the drain hole is set on the side close to the indoor motor, or is limited by the installation environment, and can only be set on one side of the air conditioner indoor unit, and the drain hole is set on the side close to the indoor motor; in order to ensure smooth drainage, the air conditioner indoor unit is generally installed horizontally or tilted to ensure that the position of the drain pipe is low, which is convenient for drainage; when the drain pipe is blocked, the condensed water flowing down the indoor heat exchanger cannot be discharged through the drain pipe in time. The water receiving tray includes a first water receiving tray located on the front side of the snail tongue air duct, and the rear side wall of the first water receiving tray is generally the lowest point of the water receiving tray. When the air conditioner indoor unit is tilted, the front side wall of the motor cavity is the lowest point of the water receiving tray. When the drain pipe is blocked, water generally enters the motor cavity, and short circuit is likely to occur when water contacts live parts, and water entering the motor cavity is likely to damage the indoor motor.

[0287] In the present application, the front volute tongue may include at least a portion of the first rear wall, that is, at least a portion of the first rear wall is a portion of the front volute tongue.

[0288] In this application, reference is made to Figure 36-Figure 37 The second rear wall may include a motor cavity front side wall 321 located at the front side of the motor cavity.

[0289] In the present application, along the length direction of the main body, the connection between the second rear wall and the first rear wall can be located on a side of the motor cavity close to the indoor fan.

[0290] In a height direction of the main body, the first rear wall may be lower than the second rear wall.

[0291] In the present application, the end of the first rear wall connected to the second rear wall is set lower than the second rear wall, so that when the air-conditioning indoor unit is slightly tilted, the end of the first rear wall connected to the second rear wall can be as close to the lowest point of the side wall of the first water receiving tray as possible; and because the connection between the first rear wall and the second rear wall is located on the side of the motor cavity close to the indoor fan, when the drain pipe is blocked or the drain hole is blocked, the condensed water in the first water receiving tray will not flow into the motor cavity as much as possible, but will flow to the side of the motor cavity close to the snail-tongue air duct, thereby avoiding water from affecting the indoor motor.

[0292] In the present application, when the indoor motor is an external rotor motor, the end of the first rear wall connected to the second rear wall is set lower than the second rear wall, so that when the air-conditioning indoor unit is slightly tilted, the end of the first rear wall connected to the second rear wall is as close to the lowest point of the side wall of the first water receiving tray as possible. In addition, since the connection between the first rear wall and the second rear wall is located on the side of the motor cavity close to the indoor fan, when the drain pipe is blocked or the drain hole is blocked, the condensed water in the first water receiving tray will not flow into the motor cavity as much as possible, but will flow to the side of the motor cavity close to the snail-tongue air duct, thereby avoiding water from affecting the indoor motor.

[0293] In this application, reference is made to Fig.38 The end of the first rear wall connected to the second rear wall may be the rear wall first end 331211. In the height direction of the main body, the minimum distance between the rear wall first end and the top end of the second rear wall may be the third distance L3.

[0294] In the present application, L3≥sixth parameter value. The sixth parameter value can be any value between 5mm-7mm. The sixth parameter value can be 5mm. L3≥5mm. The third distance can be not too small, and the end of the first rear wall connecting the second rear wall can be the lowest point of the side wall of the first water receiving tray when the air conditioner indoor unit is within the tilt range. Since the connection between the first rear wall and the second rear wall is located on the side of the motor cavity close to the indoor fan, when the drain pipe is blocked or the drain hole is blocked, the condensed water in the first water receiving tray will not flow into the motor cavity as much as possible, but will flow to the side of the motor cavity close to the snail-tongue air duct, thereby avoiding water from affecting the indoor motor.

[0295] In the present application, in the front-to-rear direction of the main body, the first rear wall and the front side wall of the motor cavity can be staggered.

[0296] In the front-to-back direction of the main body, the front side wall of the motor cavity can be located in front of the first rear wall. The motor connected to the indoor fan is an outer rotor motor, and the overall radial size of the outer rotor motor is larger than the diameter of the indoor fan. In order to ensure that the rotation axis of the outer rotor motor rotor is directly opposite to the rotation axis of the indoor fan, the front end of the outer rotor motor should be located in front of the indoor fan in the front-to-back direction of the main body. Therefore, the front side wall of the motor cavity can be located in front of the first rear wall, which can meet the installation requirements of the outer rotor motor. The front side wall of the motor cavity is arranged in front of the first rear wall, which can reduce the communication opening between the motor cavity and the volute tongue air duct, and reduce the gap between the rotor and the fan and the communication opening while satisfying the rotation of the rotor and the indoor fan, which can reduce the overflow of water or dust from entering the motor cavity.

[0302] In the present application, the top end of the second water retaining rib may be coplanar with the top end of the first water retaining rib.

[0303] In the present application, the top of the second water retaining rib can be located on the side of the top of the first water retaining rib close to the top of the main body, so that the second water retaining rib is higher than the first water retaining rib, and when the condensed water in the first water receiving tray overflows at the first rear wall and the second rear wall, the condensed water can be blocked to prevent the condensed water from flowing into the motor cavity.

[0304] In this application, reference is made to Figure 39-Figure 42 The overflow groove 367 may have an overflow groove notch 368 at its rear end.

[0305] In the present application, one end of the overflow groove notch close to the snail-tongue air duct can be connected to the snail-tongue air duct, so as to facilitate the water in the overflow groove to flow to the snail-tongue air duct, and to identify whether water overflows, so as to facilitate the unblocking of the drain pipe.

[0306] In the present application, the bottom surface of the overflow groove gap may not be higher than the rear end of the overflow groove bottom surface, so that the water in the overflow groove can flow into the overflow groove gap.

[0307] In this application, reference is made to Fig.40 A fourth through hole 3681 can be formed on the bottom surface of the overflow groove gap for water in the overflow groove gap to flow to the bottom of the base, and the water in the overflow groove gap can flow out of the overflow groove gap through the fourth through hole.

[0308] In the present application, one end of the overflow groove gap close to the motor cavity can be connected to the motor cavity, so as to facilitate the water in the motor cavity to flow out of the motor cavity, avoid the water flowing into the motor cavity from accumulating in the motor cavity, and avoid the water from hitting the indoor motor and causing damage to the indoor motor.

[0309] In this application, reference is made to Figure 43-Figure 44The motor cavity may have a motor cavity lowest point D3. The indoor motor has an indoor motor lowest point D4.

[0310] In the present application, the first height h1≥the seventh parameter value. The seventh parameter value may be any value between 5 mm and 7 mm. The seventh parameter value may be 5 mm. The first height h1≥5 mm. Avoid the first height being too low so that the indoor motor is too close to the lowest point of the motor cavity, which may cause the indoor motor to come into contact with water when there is water in the motor cavity, thereby damaging the indoor motor.

[0311] In the present application, in the vertical direction, the overflow height of the overflow groove gap relative to the lowest point of the motor cavity is a second height h2.

[0312] In the present application, the second height h2≥the eighth parameter value. The eighth parameter value may be any value between 0 mm and 2 mm. The eighth parameter value may be 0 mm. The second height h2≥0 mm. The lower limit of the second height is made as small as possible, so that the water in the motor cavity can flow into the fourth through hole and / or into the volute tongue air duct through the overflow groove gap.

[0313] In the present application, h1>h2, which can prevent the water in the motor cavity from contacting the indoor motor before reaching the overflow height, thereby preventing the indoor motor from being affected by water.

[0314] In the present application, the base may include a first end surface 353 of the volute tongue air duct located at one end of the volute tongue air duct close to the motor cavity.

[0317] In the present application, the fourth distance L4 ≤ the ninth parameter value. The ninth parameter value may be any value between 8 mm and 12 mm. The ninth parameter value may be 10 mm. The fourth distance L4 ≤ 10 mm avoids the connection between the first rear wall and the second rear wall from being too much offset toward the snail tongue air duct side, avoids causing the front snail tongue to be too high, and avoids causing abnormal noise in the snail tongue air duct.

[0318] In the present application, the wall surface of the first water retaining rib on the side away from the second water retaining rib can be coplanar with the first end surface of the volute tongue air duct.

[0319] In the present application, the wall surface of the first water retaining rib away from the second water retaining rib may be located on the side of the first end surface of the volute tongue air duct close to the motor cavity.
