[0059] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0060] Next, refer to Figures 1 - 23 to describe the window air conditioner 100 according to an embodiment of the present invention.

[0061] Refer to Figures 1 - 5As shown, the window air conditioner 100 is installed at the window 210 of the wall 200. A part of the window air conditioner 100 is located above the window 210, a part extends into the room from the window 210, and another part is located on the outdoor side of the window 210. The window 220 can move up and down. When the window 220 moves to the lowermost end, its bottom abuts against the top of the window air conditioner 100.

[0062] The window air conditioner 100 includes: a refrigerant circuit. In the refrigerant circuit, the refrigerant circulates successively through the compressor 60, the condenser, the decompressor, and the evaporator. One of the condenser and the evaporator is the outdoor heat exchanger 11, and the other is the indoor heat exchanger 23.

[0063] The compressor 60 is provided with an exhaust port and a suction port. The compressor 60 compresses the refrigerant, making the low-pressure refrigerant become high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor 60 from the suction port. After the compressor 60 compresses the low-pressure refrigerant into high-pressure refrigerant, the high-pressure refrigerant is discharged from the exhaust port. The refrigerant releases heat at the condenser, absorbs heat at the evaporator after decompression, and finally enters the compressor 60 from the suction port.

[0064] In the cooling mode of the window air conditioner 100, the outdoor heat exchanger 11 operates as a condenser. The exhaust port of the compressor 60 is communicated with the outdoor heat exchanger 11, so that the refrigerant compressed by the compressor 60 releases heat to the outdoor air through the outdoor heat exchanger 11 and condenses. The indoor heat exchanger 23 operates as an evaporator, so that the decompressed refrigerant absorbs the heat of the indoor air through the indoor heat exchanger 23 and evaporates.

[0065] In the heating mode of the window air conditioner 100, the outdoor heat exchanger 11 operates as an evaporator. The exhaust port of the compressor 60 is communicated with the indoor heat exchanger 23, so that the decompressed refrigerant absorbs the heat of the outdoor air through the outdoor heat exchanger 11 and evaporates. The indoor heat exchanger 23 operates as a condenser, so that the refrigerant compressed by the compressor 60 releases heat to the indoor air through the indoor heat exchanger 23 and condenses.

[0066] As Figure 6 shown, the window air conditioner 100 includes a housing 50 that forms an internal space. The housing 50 forms the overall appearance of the window air conditioner 100. The housing 50 includes a base 51, a cover 52 covering the base 51, and a panel 53 provided on the front side of the cover 52. An indoor air inlet 201 and an indoor air outlet 202 are formed on the panel 53. An outdoor air outlet 102 is formed on the cover 52. The outdoor air inlet 101 is provided on the opposite side of the panel 53.

[0067] Outdoor air enters the interior of the housing 50 from the outdoor air inlet 101 and is discharged to the outside through the outdoor air outlet 102. Indoor air enters the interior of the housing 50 from the indoor air inlet 201 and is discharged to the room through the indoor air outlet 202.

[0068] The window air conditioner 100 includes an outdoor unit 10 and an indoor unit 20. The outdoor unit 10 includes a compressor 60, an outdoor heat exchanger 11, and an outdoor fan 12. When the outdoor fan 12 operates, it sucks outdoor air from the outdoor air inlet 101 into the interior of the housing 50. The outdoor heat exchanger 11 is used to exchange heat with the outdoor air, and the outdoor air after heat exchange is discharged to the outside through the outdoor air outlet 102. The indoor unit 20 includes an indoor heat exchanger 23 and an indoor fan 27. When the indoor fan 27 operates, it sucks indoor air from the indoor air inlet 201 into the interior of the housing 50. The indoor heat exchanger 23 is used to exchange heat with the indoor air, and the indoor air after heat exchange is discharged to the inside through the indoor air outlet 202, thereby realizing the adjustment of the indoor air.

[0069] When the window air conditioner 100 operates in the cooling mode, the outdoor heat exchanger 11 serves as a condenser, and the outdoor air entering from the outdoor air inlet 101 flows to the outdoor heat exchanger 11. At the outdoor heat exchanger 11, the refrigerant releases a large amount of heat, and the outdoor air absorbs the heat of the refrigerant. The indoor heat exchanger 23 serves as an evaporator. After releasing heat at the outdoor heat exchanger 11, the refrigerant flows to the indoor heat exchanger 23. The indoor air entering from the indoor air inlet 201 flows to the indoor heat exchanger 23. At the indoor heat exchanger 23, the refrigerant absorbs the heat of the indoor air and then is discharged to the inside through the indoor air outlet 202, achieving the effect of reducing the temperature of the indoor air.

[0070] When the window air conditioner 100 operates in the heating mode, the exhaust port of the compressor 60 is communicated with the indoor heat exchanger 23. The outdoor heat exchanger 11 serves as an evaporator. After releasing heat at the indoor heat exchanger 23, the refrigerant flows to the outdoor heat exchanger 11. The outdoor air entering from the outdoor air inlet 101 flows to the outdoor heat exchanger 11. At the outdoor heat exchanger 11, the refrigerant absorbs the heat of the outdoor air. The indoor heat exchanger 23 serves as a condenser. The indoor air entering from the indoor air inlet 201 flows to the indoor heat exchanger 23. At the indoor heat exchanger 23, the refrigerant releases a large amount of heat, and the indoor air absorbs the heat of the refrigerant and then is discharged to the inside through the indoor air outlet 202, achieving the effect of increasing the temperature of the indoor air.

[0071] At least a part of the indoor unit 20 is located on the side of the window air conditioner 100 facing the inside, and the outdoor unit 10 is located on the side of the window air conditioner 100 facing the outside.

[0072] The indoor unit 20 is divided into an outdoor part 22 and an indoor part 21 in the front-rear direction. One side of the outdoor part 22 is connected to the indoor part 21, and the other side is connected to the outdoor unit 10. The indoor part 21 extends towards the interior of the room. Specifically, part of the indoor unit 20 is located indoors and part is located outdoors. The part of the indoor unit 20 located indoors is the indoor part 21, and the part of the indoor unit 20 located outdoors is the outdoor part 22. The side of the outdoor part 22 facing the interior of the room is connected to the other side of the indoor part 21 facing away from the interior of the room, and the other side of the outdoor part 22 is connected to the outdoor unit 10.

[0073] In this way, the indoor fan 27 is arranged in the outdoor part 22. The indoor fan 27 is at a certain distance from the interior of the room, which can reduce the noise generated during operation. The channel of the indoor air duct member 24 is relatively long, and the generated noise is small.

[0074] Combined Figures 1 - 4 As shown, the panel 53 is arranged on the side of the indoor part 21 facing the interior of the room. The indoor air inlet 201 and the indoor air outlet 202 are arranged on the panel 53. Indoor air enters the indoor unit 20 from the indoor air inlet 201, forms a heat exchange air flow after heat exchange in the indoor unit 20, and then enters the room from the indoor air outlet 202 to adjust the temperature of the room.

[0075] According to Figure 4 As shown, the first embodiment of the present invention is described:

[0076] The cross-sectional area of the indoor part 21 is smaller than that of the outdoor unit 10, and the lower surface of the indoor part 21 is higher than the lower surface of the outdoor unit 10. Specifically, taking the plane composed of the height direction and the width direction as the cross-section, the cross-sectional area of the indoor part 21 is smaller than that of the outdoor unit 10; or, taking the plane composed of the height direction and the front-rear direction as the cross-section, the cross-sectional area of the cross-sectional figure of the indoor part 21 in this plane is smaller than that of the outdoor unit 10. The cross-sectional area of the indoor part 21 and the outdoor part 22 can be the same, which can ensure that the occupied space of the indoor unit 20 indoors is smaller and the area of the blocked window 210 is small, ensuring that the user has an open field of vision.

[0077] Combined Figures 1 - 3 As shown, the second embodiment of the present invention is described:

[0078] The cross-sectional area of the inner chamber 21 is smaller than that of the outer chamber 22. Specifically, the inner chamber 21 is disposed directly above the window 210 and extends into the room from the window 210. The outer chamber 22 is disposed outdoors. Taking the plane formed by the height direction and the width direction as the cross-section, the cross-sectional area of the inner chamber 21 is smaller than that of the outer chamber 22; or, taking the plane formed by the height direction and the front-rear direction as the cross-section, the cross-sectional area of the cross-sectional pattern of the inner chamber 21 in this plane is smaller than that of the outer chamber 22, then it can be ensured that the indoor unit 20 occupies less space indoors, covers a small area of the window 210, and ensures that the user has an open field of vision.

[0079] As Figure 5 and Figure 11 shown, the lower surface of the inner chamber 21 is higher than the lower surface of the outer chamber 22, that is, there is a height difference between the inner chamber 21 and the outer chamber 22. Then, the lower contour of the projection of the indoor unit 20 on the plane formed by the front-rear direction and the height direction is an "L" shape, and a first step is formed on the lower side at the connection between the inner chamber 21 and the outer chamber 22. The first step abuts against the outdoor side of the window 210. The inner chamber 21 cooperates with the window 210. The part on the lower side of the outer chamber 22 protrudes relative to the inner chamber 21, that is, the lower surface of the outer chamber 22 is lower than the lower surface of the window 210. Then, the part of the outer chamber 22 abuts against the wall body 200 correspondingly, thereby reducing the space occupied by the inner chamber 21 indoors, reducing the field of vision blocked by the indoor unit 20, and ensuring that the user has an open field of vision.

[0080] Furthermore, the lower surface of the outer chamber 22 can be flush with the lower surface of the outdoor unit 10, that is, the lower surface of the inner chamber 21 is higher than the lower surface of the outdoor unit 10. Taking the plane formed by the front-rear direction and the height direction as the cross-section, the lower contour of the cross-sectional pattern of the window air conditioner 100 in this plane is an "L" shape. A first step is formed at the connection between the inner chamber 21 and the outer chamber 22. The first step abuts against the outdoor side of the window 210. The inner chamber 21 cooperates with the window 210, reducing the space occupied by the inner chamber 21 indoors, reducing the field of vision blocked by the indoor unit 20, and ensuring that the user has an open field of vision.

[0081] In addition, making the lower surface of the inner chamber 21 higher than the lower surface of the outer chamber 22 can increase the accommodation space of the outer chamber 22, further reduce the height of the inner chamber 21, further reduce the space occupied by the inner chamber 21 indoors, and further reduce the field of vision blocked by the indoor unit 20, ensuring that the user has a more open field of vision.

[0082] According to Figure 5 shown, the third embodiment of the present invention is described:

[0083] The upper surface of the interior part 21 is lower than the upper surface of the exterior part 22. There is a height difference between the upper surfaces of the interior part 21 and the exterior part 22, so the upper contour of the projection of the indoor unit part 20 on the plane composed of the front-back direction and the height direction is in an "L" shape. A second step is formed on the upper side of the connection between the interior part 21 and the exterior part 22, and the second step abuts against the window frame 2021 of the window 220. The part on the upper side of the exterior part 22 protrudes relative to the upper surface of the interior part 21. That is, the lower surface of the exterior part 22 is lower than the lower surface of the window 210, so the part of the exterior part 22 abuts against the wall body 200 correspondingly, thereby reducing the space occupied by the interior part 21 indoors, reducing the field of view blocked by the indoor unit part 20, and ensuring that the user has an open field of view.

[0084] The height difference between the upper surface of the interior part 21 and the upper surface of the exterior part 22 is h1, and the height of the window frame 2021 is h2. h1 and h2 satisfy the relationship: h2 > h1. That is to say, the height difference between the upper surface of the interior part 21 and the upper surface of the exterior part 22 is less than the height of the window frame 2021. Compared with the situation where the upper surfaces of the interior part 21 and the exterior part 22 are at the same level, using the field of view blocked by the window frame 2021 for the dimension design of the exterior part 22 can further increase the accommodation space of the exterior part 22, further reduce the height of the interior part 21, and reduce the field of view blocked by the window air conditioner 100.

[0085] As Figures 7 - 13 shown, the base 51 includes an outdoor base 511 and an indoor base 512. The compressor 60 and the outdoor heat exchanger 11 are arranged above the outdoor base 511. The outdoor base 511 has an extension part 5111 extending towards the interior part 21 in the front-back direction, and the indoor base 512 is fixedly connected to the extension part 5111.

[0086] The indoor base 512 and a part of the outer cover 52 form the housing 50 of the indoor unit part 20. The indoor air duct member 24 is arranged in the housing 50 of the indoor unit part 20.

[0087] Combined Figures 7 - 9 shown, the indoor base 512 is arranged below the indoor air duct member 24. An air outlet duct 31 is formed in the indoor air duct member 24. An air inlet duct 26 is defined between the indoor air duct member 24 and the indoor base 512. The indoor heat exchanger 23 is arranged in the air inlet duct 26. Specifically, the indoor base 512 is connected to the indoor air duct member 24, and an air inlet duct 26 is defined between the indoor air duct member 24 and the indoor base 512. The air inlet duct 26 is communicated with the indoor air inlet 201; an air outlet duct 31 is arranged in the indoor air duct member 24, and the air outlet duct 31 is communicated with the indoor air outlet 202.

[0088] The indoor heat exchanger 23 is disposed between the indoor base 512 and the indoor air duct member 24. Indoor air enters the air inlet duct 26 from the indoor air inlet 201. The indoor air exchanges heat with the refrigerant at the indoor heat exchanger 23 to form a heat exchange air flow. The heat exchange air flow enters the air outlet duct 31 and enters the room from the indoor air outlet 202, thereby adjusting the indoor temperature and realizing the cooling or heating mode of the window air conditioner 100.

[0089] As Figure 8 and Figure 9 shown, the indoor base 512 includes: a first part 5121 and a second part 5122. The first part 5121 and the second part 5122 are connected to each other. The second part 5122 is connected to the outdoor unit part 10. The lower surface of the first part 5121 is higher than that of the second part 5122. That is to say, the first part 5121 is part of the indoor part 21, the second part 5122 is part of the outdoor part 22. The first part 5121 is located on the indoor side of the second part 5122. The second part 5122 is connected to the outdoor unit part 10. The second part 5122 and the first part 5121 are located below the indoor unit part 20. Then the lower surface of the second part 5122 is lower than the lower surface of the first part 5121. That is, there is a height difference between the lower surfaces of the first part 5121 and the second part 5122. Then the lower contour of the projection of the indoor base 512 on the plane composed of the front-back direction and the height direction is "L"-shaped. A first step is formed on the lower side of the connection between the first part 5121 and the second part 5122. The first step abuts against the outdoor side of the window 210. The first part 5121 cooperates with the window 210. The part on the lower side of the second part 5122 protrudes downward relative to the first part 5121. Then the part of the second part 5122 abuts against the wall 200 correspondingly to reduce the space occupied by the indoor part 21 indoors, reduce the field of view blocked by the indoor unit part 20, and ensure that the user has an open field of view.

[0090] Refer to Figures 10 - 13As shown, the indoor air duct member 24 includes: an air inlet volute 241 and an air outlet volute 242. The air inlet volute 241 and the air outlet volute 242 are connected to each other, and a space for accommodating the indoor fan 27 is defined between the air inlet volute 241 and the air outlet volute 242. An air outlet duct 31 is provided on the air outlet volute 242. Specifically, the indoor fan 27 is disposed at the connection of the air inlet volute 241 and the air outlet volute 242. The air inlet volute 241 and the air outlet volute 242 together form a space for accommodating the indoor fan 27, so that the indoor fan 27 drives the heat exchange air flow to enter the air outlet volute 242 from the air inlet volute 241 and finally enter the room. The air inlet volute 241 is adjacent to the indoor heat exchanger 23. After the indoor air flow enters the air inlet duct 26, it exchanges heat with the refrigerant at the indoor heat exchanger 23 to form a heat exchange air flow. Driven by the indoor fan 27, the heat exchange air flow enters the air inlet volute 241 and then enters the room from the air outlet duct 31 on the air outlet volute 242, thereby adjusting the indoor temperature and realizing the cooling or heating mode of the window air conditioner 100.

[0091] As Figure 11 and Figure 12 shown, at least one partition rib 246 is provided in the air outlet duct 31, and the partition rib 246 extends in the front-rear direction. Specifically, the partition rib 246 extends in the front-rear direction, that is, the partition rib 246 extends from the outdoor side towards the indoor side. The partition rib 246 divides the air outlet duct 31 in the width direction into at least two sub-air outlet ducts 31, so that the heat exchange air flow blows out evenly in the width direction when flowing out of the air outlet duct 31, ensuring the cooling or heating effect of the window air conditioner 100.

[0092] In some embodiments of the present invention, the partition rib 246 can be one.

[0093] In addition, the partition rib 246 can improve the strength of the air outlet duct 31 and prevent the air outlet duct 31 from collapsing.

[0094] As Figure 11 shown, the air outlet volute 242 includes: a volute part 243 and a duct part 244. The volute part 243 and the duct part 244 are connected. At least two connecting rib plates 247 are provided at the connection of the duct part 244 and the volute part 243. The at least two connecting rib plates 247 extend in the front-rear direction and are spaced apart in the width direction. Specifically, the volute part 243 is connected to the air inlet volute 241, so that a space for accommodating the indoor fan 27 is defined between the volute part 243 and the air inlet volute 241. The duct part 244 extends in the front-rear direction. Connecting rib plates 247 are provided at the connection part of the duct part 244 and the volute part 243. The number of the connecting rib plates 247 can be two, increasing the connection strength between the volute part 243 and the duct part 244 and preventing the connection strength between the volute part 243 and the duct part 244 from being insufficient and cracking.

[0095] CombinedFigure 5 , Figure 6 and Figure 11 As shown in Figure 5 , Figure 6 , and Figure 11 , the indoor heat exchanger 23 is a straight plate heat exchanger and is inclined towards the interior of the room. A part of the indoor heat exchanger 23 is disposed inside the room portion 21, and another part is disposed outside the room portion 22. That is to say, since the height of the interior of the room portion 21 is minimized as much as possible, the indoor heat exchanger 23 is designed as a straight plate heat exchanger. A part of the indoor heat exchanger 23 is located outside the room portion 22, and another part of the indoor heat exchanger 23 is located inside the room portion 21. That is, the indoor heat exchanger 23 extends from outside the room portion 22 to inside the room portion 21. Then, the indoor heat exchanger 23 is inclined towards the interior of the room. The upper end and the lower end of the indoor heat exchanger 23 are respectively in contact with the upper end and the lower end of the air inlet duct 26, ensuring that the entering indoor air is in full contact with the indoor heat exchanger 23 and guaranteeing the heat exchange effect of the indoor heat exchanger 23.

[0096] As Figures 7 - 9 shown in Figures 7 - 9 , the window air conditioner 100 further includes: a partition 40. The partition 40 is disposed between the indoor unit portion 20 and the outdoor unit portion 10. The partition 40 is fixedly connected to the outdoor unit portion 10 and fixedly connected to the indoor air duct member 24. The partition 40 separates the indoor unit portion 20 and the outdoor unit portion 10. Specifically, a partition 40 is provided between the indoor unit portion 20 and the outdoor unit portion 10 to separate the internal structure of the indoor unit portion 20 from the structure of the outdoor unit portion 10, avoiding interference between the internal structures of the indoor unit portion 20 and the outdoor unit portion 10. The side of the partition 40 facing the outside is fixedly connected to the outdoor unit portion 10, and the side of the partition 40 facing the inside is fixedly connected to the indoor air duct. Thus, the outdoor unit portion 10 and the indoor unit portion 20 are connected as a whole and separated from each other.

[0097] In addition, the partition 40 can not only separate outdoor air and indoor air but also play a sound insulation role. That is, since the outdoor fan 12 is an axial flow fan and the noise of the axial flow fan is relatively large, the partition 40 can play a sound insulation role by being provided.

[0098] Furthermore, the outdoor unit portion 10 further includes: a fan bracket 13. The fan bracket 13 is disposed on the outdoor base 511 and fixedly connected to the outdoor base 511. The outdoor fan 12 is fixed on the fan bracket 13. Specifically, the fan bracket 13 is located inside the outdoor unit portion 10, and the outdoor fan 12 is fixed on the fan bracket 13. The fan bracket 13 provides a supporting force for the outdoor fan 12.

[0099] In addition, the window air conditioner 100 further includes an electric box 41. One end of the electric box 41 is fixedly connected to the fan bracket 13, and the other end is fixedly connected to the partition 40. That is to say, the electric box 41 is connected between the fan bracket 13 and the partition 40. The end of the electric box 41 facing the outdoor is connected to the upper end of the fan bracket 13, and the end of the electric box 41 facing the indoor is fixedly connected to the upper end of the partition 40. The fan bracket 13 and the partition 40 provide installation points and support forces for the electric box 41.

[0100] Combined with Figures 14 - 18 As shown, a water guide groove 254 and a first water collecting groove 258 are provided on the indoor base 512. The water guide groove 254 and the first water collecting groove 258 are communicated in the front-rear direction. Specifically, the water guide groove 254 extends in the front-rear direction, and the first water collecting groove 258 is arranged on the side of the water guide groove facing the outdoor. When the window air conditioner 100 is refrigerated, the indoor heat exchanger 23 is an evaporator. After the indoor air enters the air inlet duct 26, it exchanges heat with the refrigerant at the indoor heat exchanger 23, and the moisture in the indoor air is separated to form condensed water. The condensed water drips from the indoor heat exchanger 23 to the water guide groove 254 under the action of gravity. The water guide groove 254 is communicated with the first water collecting groove 258, and the condensed water flows from the water guide groove 254 to the first water collecting groove 258 to collect the condensed water and prevent the window air conditioner 100 from leaking.

[0101] In some embodiments, the length of the projection of the indoor heat exchanger 23 on the indoor base 512 is less than the length of the water guide groove 254. Such a design makes the condensed water generated by the heat exchange of the indoor air at the indoor heat exchanger 23 drip into the water guide groove 254, preventing the condensed water from dripping outside the water guide groove 254 and causing the window air conditioner 100 to leak.

[0102] Thus, the condensed water dripping from the indoor heat exchanger 23 drips into the water guide groove 254. The water guide groove 254 extends in the front-rear direction, guiding the condensed water to flow to the first water collecting groove 258 and finally discharging from the first water collecting groove 258, so that the condensed water of the indoor unit 20 is discharged smoothly.

[0103] According to Figure 16 and Figure 18 As shown, at least two first baffles 255 are provided on the indoor base 512. The at least two first baffles 255 extend in the front-rear direction and are spaced apart in the width direction. A water guide groove 254 is formed between two adjacent first baffles 255. That is to say, there can be multiple first baffles 255. The multiple first baffles 255 extend in the front-rear direction. The first baffles 255 extend in the plane formed by the front-rear direction and the height direction, and the first baffles 255 protrude from the surface of the indoor base 512. Two adjacent first baffles 255 form the water guide groove 254.

[0104] The first baffle 255 can enhance the structural strength of the indoor base 512. The first baffle 255 can also play a role in diverting and guiding the condensed water, so that the condensed water in the water guide groove 254 flows along the track of the first baffle 255 to the first water collection tank 258, improving the drainage efficiency of the condensed water.

[0105] Furthermore, a second baffle 256 is provided on the indoor base 512. The second baffle 256 extends to the edge of the indoor base 512 in the left - right direction. Specifically, the second baffle 256 extends from one end of the indoor base 512 in the left - right direction to the other end of the indoor base 512, that is, the second baffle 256 extends from one end of the air inlet duct 26 in the left - right direction to the other end of the air inlet duct 26. And the second baffle 256 extends along the plane formed by the left - right direction and the height direction, that is, the second baffle 256 is perpendicular to the first baffle 255, and the water guide groove 254 is also perpendicular to the second baffle 256. The second baffle 256 plays a role in blocking the condensed water, preventing the condensed water from entering the room through the indoor air inlet 201 and causing water leakage in the window air conditioner 100.

[0106] In some embodiments, the projection of the indoor heat exchanger 23 on the indoor base 512 is disposed on the side of the second baffle 256 facing the outside, that is, the edge of the projection of the indoor heat exchanger 23 on the indoor base 512 facing the inside does not exceed the second baffle 256. Then, the condensed water generated from the edge of the indoor heat exchanger 23 facing the inside will drip into the water guide groove 254, preventing the condensed water from dripping outside the water guide groove 254 and then entering the room through the indoor air inlet 201, thus causing water leakage in the window air conditioner 100.

[0107] As Figure 17 and Figure 18 shown, the indoor base 512 includes: a first part 5121 and a second part 5122. The first part 5121 and the second part 5122 are connected to each other. A first inclined surface 5125 is provided at the connection of the first part 5121 and the second part 5122. The water guide groove 254 is formed on the first part 5121, the first inclined surface 5125 and the second part 5122. Specifically, the first part 5121 and the second part 5122 are connected by the first inclined surface 5125, and there is a height difference between the first part 5121 and the second part 5122, which can make the indoor base 512 better fit the contour of the window sill and ensure the installation stability.

[0108] A first inclined surface 5125 is provided between the first part 5121 and the second part 5122. The inclination angle of the first inclined surface 5125 is approximately the same as that of the indoor heat exchanger 23, which can reduce the use of materials, lower the production cost, and is also beneficial to the flow of indoor air at the indoor heat exchanger 23.

[0109] The water guide groove 254 extends along the first part 5121, the first inclined surface 5125 and the second part 5122. That is, part of the water guide groove 254 is arranged on the first part 5121, another part is arranged on the first inclined surface 5125, and the remaining part is arranged on the second part 5122, ensuring that the condensed water generated at the indoor heat exchanger 23 drips into the water guide groove 254. When the condensed water is in the part of the water guide groove 254 on the first part 5121, it flows along the first inclined surface 5125 towards the first water collecting tank 258, and the first inclined surface 5125 plays a role in guiding the condensed water, thereby improving the drainage efficiency of the condensed water.

[0110] Referring Figure 19 As shown, the distance between the indoor heat exchanger 23 and the first inclined surface 5125 is h, and h satisfies the relationship: 15mm ≤ h ≤ 25mm. That is, the distance between the indoor heat exchanger 23 and the first inclined surface 5125 is not less than 15mm and not greater than 25mm. Within this range, it does not affect the air circulation efficiency in the room and can also save materials. If the distance is too large, the indoor air will not be concentrated near the indoor heat exchanger 23. If the distance is too small, the flow of indoor air will be blocked, affecting the heat exchange efficiency.

[0111] Combined with Figure 14 and Figure 18 As shown, the indoor heat exchanger 23 and the first inclined surface 5125 are arranged oppositely and are separated from each other. Specifically, the indoor heat exchanger 23 is arranged oppositely to the first inclined surface 5125, then the indoor heat exchanger 23 is inclined towards the room, the upper end and the lower end of the indoor heat exchanger 23 are respectively in contact with the upper end and the lower end of the air inlet duct 26, and the indoor heat exchanger 23 and the first inclined surface 5125 are separated, ensuring that the indoor air entering the air inlet duct 26 is fully in contact with the indoor heat exchanger 23 and ensuring the heat exchange effect of the indoor heat exchanger 23;

[0112] As Figures 6 - 9 shown, a water retaining rib 257 is further arranged on the indoor base 512. The water retaining rib 257 is arranged at the end of the water guide groove 254 and at one end of the indoor heat exchanger 23. A first water collecting tank 258 is arranged on one side of the water retaining rib 257 in the left - right direction. Specifically, the water retaining rib 257 extends in the left - right direction. The water retaining rib 257 can be arranged on the second part 5122. The water retaining rib 257 is arranged oppositely to the outdoor - facing end of the indoor heat exchanger 23. Then the water retaining rib 257 plays a guiding role in the condensed water generated by the indoor heat exchanger 23, enabling the condensed water to enter the first water collecting tank 258 and be discharged through the first water collecting tank 258.

[0113] Furthermore, there can be two water retaining ribs 257. The two water retaining ribs 257 are respectively located on both sides of the first water collecting tank 258 in the left - right direction. The two water retaining ribs 257 guide the condensed water into the first water collecting tank 258, improving the drainage efficiency of the condensed water.

[0114] Combined Figures 14 - 18 As shown, the first water collecting tank 258 is lower than the water guiding tank 254. A water guiding hole 259 is provided at the lowest point of the first water collecting tank 258 in the up-down direction, and the water guiding hole 259 communicates with the outdoor unit part 10. That is to say, the first water collecting tank 258 is located on the second part 5122. The condensed water generated at the indoor heat exchanger 23 drips onto the first part 5121, the first inclined surface 5125 and the second part 5122, and finally converges in the first water collecting tank 258. The first water collecting tank 258 communicates with the outdoor unit part 10 through the water guiding hole 259. That is, the condensed water in the first water collecting tank 258 flows to the outdoor unit part 10 through the water guiding hole 259 to discharge the condensed water in the indoor unit part 20.

[0115] As Figures 14 - 18 shown, the outdoor unit part 10 further includes: an outdoor base 511. The outdoor base 511 is provided below the first housing. The outdoor base 511 and the indoor base 512 are fixedly connected. A second water collecting tank 5112 is provided on the outdoor base 511, and the second water collecting tank 5112 communicates with the first water collecting tank 258. That is to say, the indoor base 512 and the outdoor base 511 are connected. The outdoor base 511 is located below the indoor base 512, so that the condensed water in the first water collecting tank 258 flows to the outdoor base 511 under the action of gravity. A second water collecting tank 5112 is provided in the outdoor base 511. The second water collecting tank 5112 communicates with the first water collecting tank 258, and the condensed water flows to the second water collecting tank 5112, thereby discharging the condensed water of the indoor unit part 20 to the outdoor unit part 10.

[0116] In some embodiments, a first positioning part is provided on the indoor base 512, and a second positioning part is provided on the outdoor base 511. The first positioning part and the second positioning part are in positioning cooperation. When installing the window air conditioner 100, the indoor base 512 is positioned and mated with the outdoor base 511 from top to bottom. A first positioning part is provided on the indoor base 512, and a second positioning part is provided on the outdoor base 511. The first positioning part and the second positioning part are correspondingly arranged and in positioning cooperation to complete the preliminary connection of the indoor base 512 and the outdoor base 511. The first positioning part can be multiple, and the second positioning part can also be multiple. The multiple first positioning parts and the multiple second positioning parts correspond to each other one by one to ensure the assembly accuracy of the indoor base 512 and the outdoor base 511.

[0117] In addition, a first mounting portion is provided on the indoor base 512, and a second mounting portion is provided on the outdoor base 511. The first mounting portion and the second mounting portion are fixedly connected. Specifically, the first mounting portion and the second mounting portion are correspondingly arranged and fixedly connected so that the indoor base 512 and the outdoor base 511 are connected. The first mounting portion can be multiple, and the second mounting portion can be multiple. The multiple first mounting portions and the multiple second mounting portions are in one-to-one correspondence and fixedly connected to ensure the connection strength between the indoor base 512 and the outdoor base 511.

[0118] Combined with Figure 5 、 Figure 6 and Figure 11 As shown, the indoor heat exchanger 23 is a straight plate heat exchanger and is inclined towards the interior of the room. A part of the indoor heat exchanger 23 is arranged inside the room part 21, and another part is arranged outside the room part 22. That is to say, since the height of the inside of the room part 21 is minimized as much as possible, the indoor heat exchanger 23 is designed as a straight plate heat exchanger. A part of the indoor heat exchanger 23 is located outside the room part 22, and another part of the indoor heat exchanger 23 is located inside the room part 21. That is, the indoor heat exchanger 23 extends from outside the room part 22 to inside the room part 21, then the indoor heat exchanger 23 is inclined towards the interior of the room. The upper end and the lower end of the indoor heat exchanger 23 are respectively in contact with the upper end and the lower end of the air inlet duct 26, ensuring that the incoming indoor air is in full contact with the indoor heat exchanger 23 and ensuring the heat exchange effect of the indoor heat exchanger 23.

[0119] Referring to Figure 4 As shown, in some other embodiments of the present invention, arranging a part of the indoor heat exchanger 23 inside the room part 21 and a part outside the room part 22 can reduce the volume of the inside of the room part 21, thereby reducing the volume of the window air conditioner 100, which is beneficial to reducing the product cost.

[0120] Referring to Figure 3 and Figure 5 As shown, in some embodiments of the present invention, the indoor heat exchanger 23 can be entirely located outside the room part 22. In this way, the length of the inside of the room part 21 is longer, the height of the inside of the room part 21 can be reduced, the view of the window 220 occupied by the window air conditioner 100 is reduced, and the user experience is better.

[0121] Referring to Figure 9 and Figure 12As shown, the indoor base 512 further includes: a bottom plate 5123 and two side plates 5124. The two side plates 5124 are disposed on one side of the bottom plate 5123 facing the indoor air duct member 24 and are spaced apart from each other. A second inclined surface 302 is provided on the side of the two side plates 5124 facing the indoor heat exchanger 23. The second inclined surface 302 is adapted to and sealed with the indoor heat exchanger 23. That is to say, an air inlet duct 26 is defined between the bottom plate 5123, the two side plates 5124 and the indoor air duct member 24. A second inclined surface 302 is provided on the side of the two side plates 5124 facing the indoor heat exchanger 23. The second inclined surface 302 has the same inclination as the indoor heat exchanger 23, can be adapted to and sealed with the indoor heat exchanger 23, so as to improve the heat exchange efficiency between the indoor air and the indoor heat exchanger 23 and reduce the heat loss during the heat exchange process.

[0122] Referring to Figure 9 and Figure 12 As shown, a third inclined surface 303 is formed on the side of the indoor air duct member 24 facing the indoor heat exchanger 23. The third inclined surface 303 is adapted to and sealed with the indoor heat exchanger 23, and the third inclined surface 303 is fixedly connected to the indoor heat exchanger 23. Similarly, the third inclined surface 303 has the same inclination as the indoor heat exchanger 23, can be adapted to and sealed with the indoor heat exchanger 23, and can reduce the air volume loss when the indoor air enters the indoor air duct member 24 and increase the air volume entering the indoor air duct member 24.

[0123] Moreover, through the mutual sealing between the third inclined surface 303 and the indoor heat exchanger 23, outdoor air can also be prevented from entering the indoor air passage.

[0124] Referring to Figure 20 As shown, an installation protrusion 32 is provided on the lower surface of the indoor air duct member 24; the indoor unit part 20 further includes: a sealing member, and the sealing member is fitted on one side of the installation protrusion 32, and the indoor heat exchanger 23 abuts against the sealing member. Specifically, an installation protrusion 32 is provided on the lower surface of the air outlet volute 242, and the sealing member is attached to the installation protrusion 32 to seal the indoor heat exchanger 23, which can prevent the fluid in the indoor heat exchanger 23 from leaking, and can also prevent external substances, dust, etc. from entering the indoor heat exchanger 23 and affecting the operation of the window air conditioner 100.

[0125] Wherein, the sealing member can be made of rubber material or foam material.

[0126] Referring to Figure 19 and Figure 21As shown in the figure, the indoor unit 20 further includes: two connecting end plates 33, which are connected to both sides of the indoor heat exchanger 23 in the left-right direction, and the lower sides of the connecting end plates 33 are connected to the indoor base 512. By connecting the connecting end plates 33 and the indoor base 512, the indoor heat exchanger 23 can be fixed on the indoor base 512, improving the stability inside the window air conditioner 100.

[0127] Refer to Figures 19 - 21 As shown in the figure, the indoor base 512 includes: a bottom plate 5123 and two side plates 5124. The two side plates 5124 are arranged on one side of the bottom plate 5123 facing the air duct member and are spaced apart from each other. A main water trough 51231 is formed between the two side plates 5124 and the bottom plate 5123, and the lower sides of the connecting end plates 33 are fixedly connected to the side plates 5124. That is to say, the two side plates 5124 are arranged above the bottom plate 5123 and are respectively located on the left and right sides of the bottom plate 5123. A main water trough 51231 is formed between the two side plates 5124 and the bottom plate 5123. The main water trough 51231 is mainly used for collecting and guiding condensed water. Since the indoor heat exchanger 23 is inclined, the main water trough 51231 is parallel to the direction of the indoor heat exchanger 23. The condensed water dripping from the indoor heat exchanger 23 flows along the main water trough 51231 and is finally discharged from the indoor unit 20, preventing the condensed water from dripping to an inappropriate position and damaging other electronic components.

[0128] Refer to Figure 22 As shown in the figure, there is a gap between the edges of the side plate 5124 and the bottom plate 5123. A first flanging 51232 is provided at the edge of the bottom plate 5123. The connecting end plate 33 is arranged on the side of the side plate 5124 facing the first flanging 51232. An auxiliary water trough 51233 is formed between the first flanging 51232 and the side plate 5124, and the auxiliary water trough 51233 is communicated with the main water trough 51231. That is, the main water trough 51231 corresponds to the position of the indoor heat exchanger 23, and the auxiliary water trough 51233 is located on one side of the indoor heat exchanger 23, which is used to enhance the drainage effect of the condensed water. When the main water trough 51231 has poor drainage or the condensed water overflows due to other reasons, the auxiliary water trough 51233 can receive and guide the condensed water, reducing the risk of water leakage and improving the system operation efficiency.

[0129] Refer to Figures 21 - 23As shown, the indoor unit 20 further includes: an indoor control box 42. An installation plate 35 is provided on one side of the indoor air duct member 24 in the left-right direction. The installation plate 35 is disposed above the auxiliary water guide trough 51233, and the indoor control box 42 is fixed to the installation plate 35. In this way, the installation plate 35 can provide a firm support platform for the indoor control box 42, preventing the indoor control box 42 from loosening or moving during transportation, installation or use, thereby ensuring the stability and safety of the electrical components. The installation plate 35 is disposed above the auxiliary water guide trough 51233, keeping the indoor control box 42 away from the water source and ensuring safety. Moreover, the installation plate 35 is connected to the indoor air duct member 24, which helps to reduce the vibration and noise that may be generated when the indoor control box 42 is operating, improving the user experience.

[0130] In addition, a limiting flange is further provided on the installation plate 35 for fixing the position of the indoor control box 42 to prevent the indoor control box 42 from moving.

[0131] Referring to Figure 23 As shown, at least one limiting rib 34 is provided on the outer side of the side plate 5124, and a limiting groove 36 is provided on the connecting end plate 33. The limiting rib 34 and the limiting groove 36 are in limiting cooperation. Specifically, a protruding limiting rib 34 is provided at the connection between the side plate 5124 and the connecting end plate 33. The connecting end plate 33 is recessed inward at a position opposite to the limiting rib 34 to form a limiting groove 36. The limiting groove 36 and the limiting rib 34 are in limiting cooperation, which can ensure accurate positioning when the side plate 5124 and the connecting end plate 33 are connected, making the assembly process simpler and easier. Moreover, the limiting rib 34 can also limit the left-right movement of the connecting end plate 33, improving the stability of the air-conditioning system.

[0132] Furthermore, a first sealing plate is provided on the front side of the connecting end plate 33. A sealing structure is formed between the first sealing plate, the indoor base 512 and the indoor air duct member 24 to close the air inlet channel; and / or, a second sealing plate is provided on the rear side of the connecting end plate 33. A sealing structure is formed between the second sealing plate, the indoor base 512 and the air duct member to close the air inlet channel. That is, sealing structures can be provided on both the front and rear sides of the connecting end plate 33. The first sealing plate and the second sealing plate can be perpendicular to the connecting end plate 33. Since the connecting end plate 33, the side plate 5124 and the part of the indoor air duct member 24 connected to the connecting end plate 33 are all parallel to each other and there are gaps between them, the first sealing plate and the second sealing plate can be used to close the gaps, preventing air from overflowing through the gaps, reducing heat loss, improving the energy efficiency of the window air conditioner 100, and also helping to reduce the noise that may be generated during system operation, improving the user experience.

[0133] Referring to Figure 22As shown, on the side of the indoor base 512 facing the indoor heat exchanger 23, a second flanging 38 is provided, and the indoor heat exchanger 23 abuts against the second flanging 38. On the one hand, the second flanging 38 can improve the structural strength of the indoor heat exchanger 23, prevent the indoor heat exchanger 23 from deforming or vibrating during operation, reduce the risk of mechanical failures.
