[0055] A window air conditioner 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings. In particular, the drawings show... Figure 4 , Figures 16-19 The lines with arrows indicate the direction of airflow.
[0056] like Figures 1-7 , Figures 10-15As shown, a window air conditioner 100 according to an embodiment of the present invention includes a housing 1, a fan assembly, and a heat exchanger assembly. The housing 1 has an outdoor air inlet 1221, an outdoor air outlet 1222, an indoor air inlet 1211, an indoor air outlet 1212, a fresh air inlet 1223, a first fresh air outlet 1213, and a second fresh air outlet 1214. The housing 1 has an outdoor air duct 43, an indoor air duct 44, a first fresh air duct 45, and a second fresh air duct 48. The outdoor air duct 43 connects the outdoor air inlet 1221 and the outdoor air outlet 1222. The indoor air duct 44 connects the indoor air inlet 1211 and the indoor air outlet 1212. The first fresh air duct 45 connects the fresh air inlet 1223 and the first fresh air outlet 1213. The second fresh air duct 48 connects the fresh air inlet 1223 and the second fresh air outlet 1214. After the window air conditioner 100 is installed on the window, the outdoor air inlet 1221, the outdoor air outlet 1222 and the fresh air inlet 1223 are all connected to the outside, and the indoor air inlet 1211, the indoor air outlet 1212, the first fresh air outlet 1213 and the second fresh air outlet 1214 are all connected to the inside.
[0057] The fan assembly includes an outdoor fan wheel 21, an indoor fan wheel 22, a first fresh air fan wheel 231, and a second fresh air fan wheel 232. The outdoor fan wheel 21 is located in an outdoor air duct 43, the indoor fan wheel 22 is located in an indoor air duct 44, the first fresh air fan wheel 231 is located in a first fresh air duct 45, and the second fresh air fan wheel 232 is located in a second fresh air duct 48.
[0058] When the heat exchanger assembly is working, the compressed refrigerant flows sequentially through the outdoor heat exchanger 31 and the indoor heat exchanger 32, and then flows back to the compressor from the indoor heat exchanger 32. This allows the air flowing through the indoor heat exchanger 32 to be cooled and the air flowing through the outdoor heat exchanger 31 to be heated.
[0059] According to an embodiment of the present invention, the window air conditioner 100 provides a first fresh air outlet 1213 and a second fresh air outlet 1214 on the casing 1, and provides a first fresh air duct 45 and a second fresh air duct 48 inside the casing 1. The first fresh air impeller 231 is disposed in the first fresh air duct 45, and the second fresh air impeller 232 is disposed in the second fresh air duct 48. This allows the window air conditioner 100 to deliver a large amount of fresh air into the room, thereby improving the air quality improvement effect of the window air conditioner 100 and thus improving the user experience.
[0060] According to some embodiments of the present invention, such as Figures 1-7 , Figures 10-15As shown, the fan assembly also includes a first motor 24 and a second motor 25. The outdoor impeller 21 and the first fresh air impeller 231 are both connected to the first motor 24, and the indoor impeller 22 and the second fresh air impeller 232 are both connected to the second motor 25. Therefore, when the first motor 24 is working, it can simultaneously drive the outdoor impeller 21 and the first fresh air impeller 231. When the second motor 25 is working, it can simultaneously drive the indoor impeller 22 and the second fresh air impeller 232. This eliminates the need for separate motors to drive the first fresh air impeller 231 and the second fresh air impeller 232, reducing the number of parts, lowering the overall complexity of the machine, making the overall structure compact, and contributing to a smaller overall size.
[0061] Both the indoor fan wheel 22 and the second fresh air fan wheel 232 are connected to the second motor 25. When the window air conditioner 100 is working, the second motor 25 can drive the indoor fan wheel 22 and the second fresh air fan wheel 232 to rotate. When the indoor fan wheel 22 rotates, indoor air can flow into the indoor air duct 44 from the indoor air inlet 1211 under the drive of the indoor fan wheel 22, and then flow through the indoor heat exchanger 32 and into the room from the indoor air outlet 1212. When the heat exchanger assembly is working, the indoor air flows into the room after exchanging heat with the indoor heat exchanger 32, which can improve the indoor temperature. When the second fresh air fan wheel 232 rotates, outdoor fresh air can flow into the second fresh air duct 48 from the fresh air inlet 1223 under the drive of the second fresh air fan wheel 232, and then flow into the room from the second fresh air outlet 1214, which improves the indoor air quality.
[0062] Both the outdoor fan wheel 21 and the first fresh air fan wheel 231 are connected to the first motor 24. When the window air conditioner 100 is working, the first motor 24 can drive the outdoor fan wheel 21 to rotate. Outdoor air can flow into the outdoor air duct 43 from the outdoor air inlet 1221 under the drive of the outdoor fan wheel 21, and then flow through the outdoor heat exchanger 31. After exchanging heat with the outdoor heat exchanger 31, the outdoor air flows to the outside from the outdoor air outlet 1222. When the heat exchanger assembly is working, the outdoor air flows to the outside after exchanging heat with the outdoor heat exchanger 31, which can realize the heating and / or cooling of the window air conditioner 100. When the first fresh air fan wheel 231 rotates, outdoor fresh air can flow into the first fresh air duct 45 from the fresh air inlet 1223 under the drive of the first fresh air fan wheel 231, and then flow into the room from the first fresh air outlet 1213, improving the indoor air quality.
[0063] When the window air conditioner 100 is heating or cooling, the outdoor fan wheel 21 and the indoor fan wheel 22 have a large difference in rotation speed. Compared to air conditioners where the fresh air impeller 23 and the outdoor impeller 21 share a motor, in this case, the outdoor impeller 21 and the first fresh air impeller 231 share a first motor 24, and the indoor impeller 22 and the second fresh air impeller 232 share a second motor 25. When the first motor 24 and the second motor 25 are working, the outdoor impeller 21 and the first fresh air impeller 231 rotate synchronously, and the indoor impeller 22 and the second fresh air impeller 232 rotate synchronously at the same speed. This ensures that the wind speed of the fresh air blown out from the second fresh air outlet 1214 is approximately the same as the wind speed of the indoor air blown out from the indoor air outlet 1212, making the wind speed of the air blown into the room by the window air conditioner 100 more uniform and the air blown into the user by the window air conditioner 100 more comfortable. At the same time, the simultaneous air outlets of the first fresh air outlet 1213 and the second fresh air outlet 1214 can increase the fresh air output and improve the indoor environmental quality.
[0064] Compared to air conditioners where the fresh air impeller 23 and the outdoor impeller 21 share a motor, when the fresh air impeller 23 or the motor driving the fresh air impeller 23 fails, both the fresh air impeller 23 and the second motor 25 are located indoors, making it easier for operators to maintain.
[0065] For example, the window air conditioner 100 may also include a fresh air purification module 63, which is located at the fresh air inlet 1223. The fresh air purification module 63 can be a purification filter or an air purifier. When the window air conditioner 100 is operating, as the first fresh air impeller 231 and the second fresh air impeller 232 drive outdoor air from the fresh air inlet 1223 into the first fresh air duct 45 and the second fresh air duct 48, the fresh air purification module 63 purifies the air flowing into the first fresh air duct 45 and the second fresh air duct 48, making the outdoor air blown out from the first fresh air outlet 1213 and the second fresh air outlet 1214 cleaner, thereby improving the air quality in the indoor environment.
[0066] According to some embodiments of the present invention, such as Figure 9 and Figure 12As shown, both the first motor 24 and the second motor 25 are dual-shaft motors. The outdoor fan wheel 21 and the first fresh air fan wheel 231 are connected to the two output shafts of the first motor 24, and the indoor fan wheel 22 and the second fresh air fan wheel 232 are connected to the two output shafts of the second motor 25, respectively. Compared to air conditioners where the fresh air impeller 23 is indirectly driven by a motor through the outdoor impeller 21, the first fresh air impeller 231 is directly connected to the first motor 24, and the second fresh air impeller 232 is directly connected to the second motor 25. The connection between the first fresh air impeller 231 and the first motor 24, and the second fresh air impeller 232 and the second motor 25, is more reliable. The first motor 24 directly drives the first fresh air impeller 231 and the outdoor impeller 21 to rotate, and the second motor 25 directly drives the second fresh air impeller 232 and the indoor impeller 22 to rotate. This can reduce or avoid the impact of the outdoor impeller 21 and the indoor impeller 22 on the first fresh air impeller 231 and the second fresh air impeller 232, improve the reliability of the fan assembly, ensure the normal operation of the indoor impeller 22 and the second fresh air impeller 232, improve the reliability of the window air conditioner 100, and improve the overall performance of the window air conditioner 100.
[0067] According to some embodiments of the present invention, the fan assembly further includes a first motor 24, a second motor 25, a third motor, and a fourth motor. The outdoor fan wheel 21 is connected to the first motor 24, the first fresh air fan wheel 231 is connected to the second motor 25, the indoor fan wheel 22 is connected to the third motor, and the second fresh air fan wheel 232 is connected to the fourth motor. This configuration allows the outdoor fan wheel 21 to be controlled by the first motor 24, the first fresh air fan wheel 231 to be controlled by the second motor 25, the indoor fan wheel 22 to be controlled by the third motor, and the second fresh air fan wheel 232 to be controlled by the fourth motor. This improves the reliability of the window air conditioner 100's operation, avoids the problem of one motor failure affecting the operation of other fan wheels, and also allows for reasonable control of the speed of different fan wheels by different motors, thus improving the operating efficiency of the window air conditioner 100 and enhancing the user experience.
[0068] According to some embodiments of the present invention, such as Figures 7-15 As shown, both the outdoor fan 21 and the indoor fan 22 are cross-flow fans; and / or, both the first fresh air fan 231 and the second fresh air fan 232 are cross-flow fans. Specifically, it is possible that only the outdoor fan 21 and the indoor fan 22 are cross-flow fans, or only the first fresh air fan 231 and the second fresh air fan 232 are cross-flow fans, or all three fan types—outdoor fan 21, indoor fan 22, first fresh air fan 231, and second fresh air fan 232—are cross-flow fans. By configuring the indoor fan 22 as a cross-flow fan, when the heat exchanger assembly is working, the indoor fan 22 can drive more indoor air to flow through the indoor heat exchanger 32 per unit time, thereby accelerating the efficiency of the window air conditioner 100 in regulating the indoor ambient temperature.
[0069] By configuring the outdoor fan 21 as a cross-flow fan, when the heat exchanger assembly is working, the outdoor fan 21 can drive more airflow through the outdoor heat exchanger 31 per unit time, thereby improving the heat exchange efficiency between the outdoor heat exchanger 31 and the outdoor air, and thus improving the working efficiency of the heat exchanger assembly. By configuring the first fresh air fan 231 and the second fresh air fan 232 as cross-flow fans, when the first fresh air fan 231 and the second fresh air fan 232 are working, they can drive more outdoor airflow into the room per unit time, improving the effect of the window air conditioner 100 on improving indoor air quality and enhancing the overall performance of the window air conditioner 100. This configuration improves the working efficiency of the heat exchanger assembly and enhances the overall performance of the window air conditioner 100.
[0070] According to some embodiments of the present invention, such as Figures 7-19 As shown, the first fresh air duct 45 and the second fresh air duct 48 are arranged horizontally, as are the outdoor duct 43 and the indoor duct 44. The first fresh air duct 45 and the second fresh air duct 48 are located above the outdoor duct 43 and the indoor duct 44. Since the air in the indoor duct 44 enters through the outdoor air inlet 1221 and exits through the outdoor air outlet 1222, and the air in the indoor duct 44 enters through the indoor air inlet 1211 and exits through the indoor air outlet 1212, arranging the indoor ducts 44 horizontally ensures that the indoor air flowing through the indoor duct 44 does not interfere with the outdoor air flowing through the outdoor duct 43, thus reducing the vertical space occupied by the window air conditioner 100 and making its structure more compact. Since the air in the first fresh air duct 45 and the second fresh air duct 48 enters through the fresh air inlet 1223 and is discharged through the first fresh air outlet 1213 and the second fresh air outlet 1214 respectively, arranging the first fresh air duct and the second fresh air duct 48 in the horizontal direction can ensure that the fresh air flowing through the first fresh air duct 45 does not interfere with the fresh air flowing through the second fresh air duct 48, thereby making the window air conditioner 100 occupy less space in the vertical direction and making the structure of the window air conditioner 100 more compact.
[0071] Since the first fresh air impeller 231 and the second fresh air impeller 232 need to drive outdoor air into the room, placing the first fresh air duct 45 and the second fresh air duct 48 above the outdoor duct 43 and the indoor duct 44 can prevent the first fresh air duct 45 and the second fresh air duct 48 from interfering with or affecting each other with the outdoor duct 43 and the indoor duct 44, making the layout more reasonable.
[0072] According to some embodiments of the present invention, such as Figures 7-9As shown, the outdoor fan wheel 21 and the first fresh air fan wheel 231 are coaxially arranged, and the indoor fan wheel 22 and the second fresh air fan wheel 232 are coaxially arranged. This makes full use of the vertical space inside the room and prevents the window air conditioner 100 from encroaching too much on the user's activity space. For example, when the window air conditioner 100 is installed on a window, it can prevent the window from occupying too much of the horizontal space of the window, making the user's view wider.
[0073] The outdoor fan wheel 21 and the first fresh air fan wheel 231 are coaxially arranged. When the first motor 24 drives the outdoor fan wheel 21 and the first fresh air fan wheel 231 to rotate, the force on the first motor 24 in the axial direction can be more balanced, making the rotation of the first motor 24 more stable. At the same time, it can also reduce or avoid the eccentricity of the outdoor fan wheel 21 and the first fresh air fan wheel 231 under their own weight, so that the first motor 24 can drive the outdoor fan wheel 21 and the first fresh air fan wheel 231 to rotate more stably. This can further reduce the noise generated by the window air conditioner 100 during operation and improve the overall performance of the window air conditioner 100.
[0074] The indoor fan 22 and the second fresh air fan 232 are coaxially arranged. When the second motor 25 drives the indoor fan 22 and the second fresh air fan 232 to rotate, the force on the second motor 25 in the axial direction can be more balanced, making the rotation of the second motor 25 more stable. At the same time, it can also reduce or avoid the eccentricity of the indoor fan 22 and the second fresh air fan 232 under their own weight, so that the second motor 25 can drive the indoor fan 22 and the second fresh air fan 232 to rotate more stably. This can further reduce the noise generated by the window air conditioner 100 during operation and improve the overall performance of the window air conditioner 100.
[0075] Optionally, the diameter of the first fresh air impeller 231 can be equal to the diameter of the outdoor impeller 21, and the diameter of the second fresh air impeller 232 can be equal to the diameter of the indoor impeller 22. When the first motor 24 drives the outdoor impeller 21 and the first fresh air impeller 231, and the second motor 25 drives the indoor impeller 22 and the fresh air impeller 232 to rotate, the force exerted by the outdoor impeller 21 on the first motor 24 in the horizontal direction and the force exerted by the first fresh air impeller 231 on the first motor 24 in the horizontal direction can be approximately the same, and the force exerted by the indoor impeller 22 on the second fresh air impeller 232 in the horizontal direction can be approximately the same. The force applied by motor 25 and the force applied by the second fresh air impeller 232 to the second motor 25 in the horizontal direction are approximately the same. This balances the forces acting on the first motor 24 or the second motor 25 in the horizontal direction, allowing the first motor 24 and the second motor 25 to operate more smoothly. This, in turn, makes the outdoor impeller 21, indoor impeller 22, first fresh air impeller 231 and second fresh air impeller 232 rotate more smoothly, thereby reducing the noise generated by the window air conditioner 100 during operation and improving the overall performance of the window air conditioner 100.
[0076] According to some embodiments of the present invention, such as Figures 14-19 As shown, the first fresh air impeller 231 and the second fresh air impeller 232 are at least partially offset in the indoor-to-outdoor direction. Specifically, since the first fresh air duct 45 and the second fresh air duct 48 are located above the outdoor duct 43 and the indoor duct 44, the outdoor impeller 21 and the indoor impeller 22 are at least partially offset in the indoor-to-outdoor direction. This arrangement allows for a more compact structure of the window air conditioner 100, providing more space for other components and reducing the space occupied by the window air conditioner 100, thereby improving the user experience.
[0077] According to some embodiments of the present invention, such as Figures 5-7 , Figures 10-12 As shown, the compressor of the window air conditioner 100 is located below the indoor air duct 44, and the compressor of the window air conditioner 100 is horizontally opposite to the outdoor air duct 43. This makes the structure of the window air conditioner 100 more compact and reduces the space occupied by the window air conditioner 100. Compared with the window air conditioner 100 where the compressor is located below the indoor air duct 44 and the outdoor air duct 43, the length of the outdoor air duct 43 in the vertical direction can be extended, the area of the outdoor air inlet 1221 and the outdoor air outlet 1222 can be increased, the air intake of the outdoor air duct 43 can be increased, and the heat exchange efficiency of the heat exchanger assembly can be improved.
[0078] According to some embodiments of the present invention, such as Figures 1-7 , Figures 14-19As shown, the fresh air inlet 1223, outdoor air inlet 1221, and outdoor air outlet 1222 are all formed on the rear side wall of the casing 1. The outdoor air inlet 1221 and outdoor air outlet 1222 are arranged in a left-right direction, and the fresh air inlet 1223 is located above the outdoor air outlet 1222 and outdoor air inlet 1221. By setting the outdoor air inlet 1221 and outdoor air outlet 1222 to be arranged in a left-right direction, when the outdoor fan 21 is working, after the outdoor fan 21 drives the outdoor air into the outdoor air duct 43, the outdoor air can be quickly discharged out of the outdoor air outlet 1222. This timely discharge of the outdoor air that has exchanged heat with the outdoor heat exchanger 31 from the outdoor air duct 43 can improve the heat exchange efficiency of the outdoor heat exchanger 31, improve the heat exchange efficiency of the heat exchanger components, and improve the overall performance of the window air conditioner 100.
[0079] At least a portion of the indoor air inlet 1211 is formed on the left side wall and / or the right side wall of the casing 1, and the indoor air outlet 1212 is formed on the front side wall of the casing 1. When at least a portion of the indoor air inlet 1211 is formed on the left side wall of the casing 1, a portion of the indoor air inlet 1211 may be formed on the left side of the front side wall of the casing 1. When the indoor fan 22 is working, the indoor fan 22 can drive the indoor air from the left side and the left front of the casing 1 into the indoor air duct 44, and then blow the air flowing into the indoor air duct 44 into the room from the indoor air outlet 1212 on the front side of the casing 1, thereby increasing the air intake of the indoor air duct 44 and realizing the function of front air outlet of the window air conditioner 100.
[0080] When the indoor air inlet 1211 is at least partially formed on the left side wall of the casing 1, when installing the window air conditioner 100 in a home environment, the user can place the right side wall of the window air conditioner 100 close to the right side of the window. For example, if the right side of the window is a wall, the user can place the right side wall of the window air conditioner 100 against the wall. This eliminates the need to reserve indoor air intake space on the right side of the casing 1, reduces the extra space occupied by the window air conditioner 100, and does not appear obtrusive in the overall home environment, nor does it affect the normal operation of the window air conditioner 100.
[0081] When at least a portion of the indoor air inlet 1211 is formed on the right side wall of the casing 1, a portion of the indoor air inlet 1211 may be formed on the right and left sides of the front side wall of the casing 1. When the indoor fan 22 is working, the indoor fan 22 can drive the indoor air from the right side and the right front of the casing 1 into the indoor air duct 44, and then blow the air flowing into the indoor air duct 44 into the room from the indoor air outlet 1212 on the front side of the casing 1, thereby increasing the air intake of the indoor air duct 44 and realizing the function of front air outlet of the window air conditioner 100.
[0082] When the indoor air inlet 1211 is at least partially formed on the right side wall of the casing 1, when installing the window air conditioner 100 in a home environment, the user can place the left side wall of the window air conditioner 100 close to the left side of the window. For example, if the left side of the window is a wall, the user can place the left side wall of the window air conditioner 100 against the wall. This eliminates the need to reserve indoor air intake space on the left side of the casing 1, reduces the extra space occupied by the window air conditioner 100, and does not appear obtrusive in the overall home environment, nor does it affect the normal operation of the window air conditioner 100.
[0083] According to some embodiments of the present invention, such as Figures 1-4 , Figure 16 and Figure 17 As shown, the first fresh air outlet 1213 and the second fresh air outlet 1214 are respectively formed on the left and right side walls of the casing 1. Specifically, outdoor fresh air enters the first fresh air duct 45 and the second fresh air duct 48 through the fresh air inlet 1223. The fresh air in the first fresh air duct 45 is discharged from the first fresh air outlet 1213, and the fresh air in the second fresh air duct 48 is discharged from the second fresh air outlet 1214. This arrangement allows the air conditioner to provide wraparound airflow from both sides, offering users a comfortable, enveloping experience with abundant fresh air, thereby improving the user experience.
[0084] For example, in Figures 1-4 In the illustrated embodiment, the first fresh air outlet 1213 is formed on the left side wall of the housing 1, and the second fresh air outlet 1214 is formed on the right side wall of the housing 1. The first fresh air outlet 1213 and the second fresh air outlet 1214 are offset in the direction from indoor to outdoor. Outdoor fresh air enters the first fresh air duct 45 and the second fresh air duct 48 from the fresh air inlet 1223. The fresh air in the first fresh air duct 45 is discharged from the first fresh air outlet 1213, and the fresh air in the second fresh air duct 48 is discharged from the second fresh air outlet 1214, forming a wraparound air supply effect.
[0085] According to some embodiments of the present invention, such as Figures 5-19 As shown, the window air conditioner 100 also includes an air duct assembly, which is disposed within the casing 1. The air duct assembly includes an air duct support component 42 and an air duct cover component 41 that are connected horizontally. The air duct support component 42 and the air duct cover component 41 together define an outdoor air duct 43, an indoor air duct 44, a first fresh air duct 45, and a second fresh air duct 48. For traditional fresh air duct intake, the fresh air duct is a pipe structure, which is not easy to arrange in the window air conditioner 100, and the fresh air intake is limited by the shape of the fresh air duct, resulting in a small intake volume. By setting the air duct support component 42 and the air duct cover component 41 to define the fresh air duct, the shape of the first fresh air duct 45 and the second fresh air duct 48 is not limited by the pipe, which simplifies the fresh air duct structure and increases the fresh air intake volume.
[0086] When assembling the air duct assembly, the air duct support component 42 can be aligned with the air duct cover component 41 in the horizontal direction first. Then, the air duct support component 42 and the air duct cover component 41 can be joined together in the horizontal direction. Finally, fasteners can be used to secure the air duct support component 42 and the air duct cover component 41 together. Compared with the vertical joining method, this method is more convenient for assembling the air duct support component 42 and the air duct cover component 41, and can improve assembly efficiency.
[0087] According to some embodiments of the present invention, such as Figures 5-19 As shown, both the duct support component 42 and the duct cover component 41 are integrally formed. Specifically, the duct support component 42 and the duct cover component 41 are integrally formed parts. This can improve the structural strength of the duct support component 42 and the duct cover component 41, and extend their service life.
[0088] Compared to traditional window air conditioners 100, such as those where each duct is composed of two duct components joined together, and those where the outdoor duct 43 component defines the outdoor duct 43, the indoor duct 44 component defines the indoor duct 44, and the fresh air duct component defines the fresh air duct, this design simplifies the modular components of the window air conditioner 100, facilitating its assembly and disassembly, cleaning, and maintenance. It also reduces the number of components, decreases production steps, improves efficiency, and lowers costs. Furthermore, by making the duct support component 42 and the duct cover component 41 a single molded part, the total material usage of the duct components can be reduced to some extent, further lowering production costs.
[0089] According to some embodiments of the present invention, such as Figures 1-17 As shown, the heat exchanger assembly also includes a fresh air heat exchanger 33, which is located within the fresh air inlet 1223. For example, the fresh air heat exchanger 33 is placed vertically, and its cross-section extends in a straight line. The first fresh air duct 45 and the second fresh air duct 48 share a single fresh air heat exchanger 33. By installing the fresh air heat exchanger 33 in the first and second fresh air ducts 45 and 48, it facilitates heat exchange between the outdoor air flowing into the first and second fresh air ducts 45 and the fresh air heat exchanger 33, thereby improving the efficiency of heat exchange between the outdoor air flowing into the first and second fresh air ducts 45 and the fresh air heat exchanger 33, and increasing the efficiency of the window air conditioner 100 in regulating indoor temperature.
[0090] The first fresh air duct 45 and the second fresh air duct 48 are isolated from the indoor air duct 44 and the outdoor air duct 43. This prevents air from the outdoor air duct 43 from flowing into the first fresh air duct 45, the second fresh air duct 48, or the indoor air duct 44, which would cause the window air conditioner 100 to blow out two types of air with large temperature differences. It also prevents air from the indoor air duct 44 or the first fresh air duct 45 and the second fresh air duct 48 from flowing into the outdoor air duct 43, which would reduce the temperature regulation efficiency of the window air conditioner 100. This allows the air flowing into the first fresh air duct 45 and the second fresh air duct 48 to exchange heat with the fresh air heat exchanger 33 and then flow into the room from the fresh air outlet, ensuring the temperature regulation efficiency of the window air conditioner 100 and the overall performance of the window air conditioner 100.
[0091] This also prevents air flowing into the first fresh air duct 45 and the second fresh air duct 48 from flowing into the outdoor air duct 43, which would result in less or no fresh air flowing into the room. This ensures the amount of fresh air blown out of the window air conditioner 100 from the first fresh air outlet 1213 and the second fresh air outlet 1214, thereby ensuring the window air conditioner 100's effect of improving the quality of the indoor air environment.
[0092] According to some embodiments of the present invention, such as Figures 5-7 As shown, the fresh air heat exchanger 33 and the indoor heat exchanger 32 are connected in parallel. For example, when the window air conditioner 100 is cooling the indoor environment, the refrigerant compressed by the compressor flows into the outdoor heat exchanger 31 after exiting the compressor. Part of the refrigerant flowing through the outdoor heat exchanger 31 flows into the fresh air heat exchanger 33, and the other part flows into the indoor heat exchanger 32. Then, it flows from the fresh air heat exchanger 33 and the indoor heat exchanger 32 back to the compressor. For example, when the window air conditioner 100 is heating the indoor environment, the refrigerant compressed by the compressor flows into the fresh air heat exchanger 33 after exiting the compressor. Part of it flows into the fresh air heat exchanger 33, and the other part flows into the indoor heat exchanger 32. Then, it flows from the fresh air heat exchanger 33 and the indoor heat exchanger 32 back to the outdoor heat exchanger 31, and from the indoor heat exchanger 32 back to the compressor to be compressed again.
[0093] When the fresh air heat exchanger 33 is connected in series with the indoor heat exchanger 32, for example, when the window air conditioner 100 is cooling the indoor environment, the refrigerant compressed by the compressor flows out of the compressor and then sequentially through the outdoor heat exchanger 31, the indoor heat exchanger 32, and the fresh air heat exchanger 33, finally flowing back to the compressor from the fresh air heat exchanger 33. When the indoor fan 22 drives indoor air into the indoor air duct 44, the air flowing through the indoor heat exchanger 32 exchanges heat with it, causing the refrigerant temperature in the indoor heat exchanger 32 to rise. The refrigerant temperature flowing into the fresh air heat exchanger 33 is also higher, which leads to poor cooling effect of the fresh air heat exchanger 33. This results in a large temperature difference between the air flowing out from the indoor outlet and the air flowing out from the fresh air outlet, causing discomfort to the user.
[0094] Connecting the fresh air heat exchanger 33 and the indoor heat exchanger 32 in parallel ensures that the temperature of the refrigerant flowing to the fresh air heat exchanger 33 and the indoor heat exchanger 32 is approximately the same. This ensures that the temperature of the air flowing out of the indoor air outlet 1212 is approximately the same as the temperature of the air flowing out of the fresh air outlet, reducing or avoiding user discomfort caused by a large temperature difference between the air flowing out of the indoor air outlet 1212 and the air flowing out of the fresh air outlet. This guarantees the cooling and heating effect of the window air conditioner 100 and improves the overall performance of the window air conditioner 100.
[0095] According to some embodiments of the present invention, such as Figures 5-7 , Figures 11-17 As shown, the fresh air heat exchanger 33 is positioned directly above the outdoor heat exchanger 31, allowing condensate on the fresh air heat exchanger 33 to flow downwards onto the outdoor heat exchanger 31. During the cooling process of the window air conditioner 100, when outdoor air flowing from the fresh air inlet 1223 into the first fresh air duct 45 and the second fresh air duct 48 passes through the fresh air heat exchanger 33, the moisture in the outdoor air condenses into cooler condensate. This condensate flows downwards from the fresh air heat exchanger 33 onto the outdoor heat exchanger 31. The outdoor radiator dissipates heat through the outdoor air driven by the outdoor fan 21 and the condensate flowing down from the fresh air heat exchanger 33, thus accelerating the heat dissipation efficiency of the outdoor heat exchanger 31, improving the cooling efficiency of the fresh air heat exchanger 33 and the indoor heat exchanger 32, speeding up the adjustment of the indoor temperature by the window air conditioner 100, and improving the overall performance of the window air conditioner 100.
[0096] According to some embodiments of the present invention, such as Figures 5-7 , Figures 11-19 As shown, the indoor heat exchanger 32 and the outdoor heat exchanger 31 are arranged side by side in the horizontal direction. The bottom surface of the outdoor heat exchanger 31 is provided with an outdoor water receiving pan 111, the bottom surface of the indoor heat exchanger 32 is provided with an indoor water receiving pan 61, and the bottom surface of the fresh air heat exchanger 33 is provided with a fresh air water receiving pan 62. A drain hole 621 is formed on the fresh air water receiving pan 62, allowing the condensate on the fresh air heat exchanger 33 to flow downwards to the outdoor heat exchanger 31 through the drain hole 621. Water in the indoor water receiving pan 61 is suitable for draining into the outdoor water receiving pan 111, and a drain hole 112 is formed on the outdoor water receiving pan 111. The housing 1 includes a main housing 12 and a chassis 11. The main housing 12 is disposed on the chassis 11, and the outdoor water receiving pan 111 is disposed on the chassis 11. The outdoor water receiving pan 111 can be integrally formed with the chassis 11.
[0097] When the window air conditioner 100 is cooling, the condensate on the fresh air heat exchanger 33 flows down its outer surface to the fresh air condensate tray 62, then flows from the drain hole 621 of the fresh air condensate tray 62 to the surface of the outdoor heat exchanger 31. After exchanging heat with the outdoor heat exchanger 31, the condensate flows from the outer surface of the outdoor heat exchanger 31 to the outdoor condensate tray 111, and finally flows out of the window air conditioner 100 from the drain hole 112. The condensate on the indoor heat exchanger 32 flows down its outer surface to the indoor condensate tray 61, then flows from the indoor condensate tray 61 into the outdoor condensate tray 111, and finally flows out of the window air conditioner 100 from the drain hole 112.
[0098] By setting up a fresh air condensate tray 62 with a drain hole 621, it is convenient to collect the condensate flowing down from the fresh air heat exchanger 33 and to guide the condensate from the fresh air heat exchanger 33 to the outdoor heat exchanger 31. By setting up an indoor condensate tray 61 to collect the condensate from the indoor heat exchanger 32 and an outdoor condensate tray 111 to collect the condensate flowing down from the outdoor heat exchanger 31 with a drain hole 112, the condensate generated during the operation of the window air conditioner 100 can be discharged in a timely manner, preventing water accumulation inside the window air conditioner 100 and ensuring the safety performance of the window air conditioner 100.
[0099] For example, the fresh air condensate tray 62 has multiple drain holes 621, which are evenly spaced along the horizontal extension direction of the outdoor heat exchanger 31. This allows the condensate flowing from the fresh air heat exchanger 33 to the fresh air condensate tray 62 to flow evenly to the outer surface of the outdoor heat exchanger 31, further improving the heat dissipation efficiency of the outdoor heat exchanger 31, improving the cooling efficiency of the fresh air heat exchanger 33 and the indoor heat exchanger 32, accelerating the speed at which the window air conditioner 100 regulates the indoor ambient temperature, and improving the overall performance of the window air conditioner 100.
[0100] The following reference Figures 1-19 A window air conditioner 100 according to a specific embodiment of the present invention is described.
[0101] Reference Figures 1-7 In this embodiment, the window air conditioner 100 includes a casing 1, a fan assembly, a heat exchanger assembly, an air duct assembly, and an electrical control component 5. The casing 1 includes a main casing 12 and a chassis 11. The bottom surface of the main casing 12 is open, and the chassis 11 is disposed on the bottom surface of the main casing 12. The air duct assembly and the compressor are disposed on the chassis 11. The main casing 12 includes a front casing 121 and a rear casing 122. The fan assembly, heat exchanger assembly, air duct assembly, and electrical control component 5 are disposed inside the casing 1.
[0102] Reference Figures 5-12The air duct assembly may include an air duct support component 42 and an air duct cover component 41. The air duct support component 42 and the air duct cover component 41 are connected in a horizontal direction. The air duct support component 42 and the air duct cover component 41 together define an outdoor air duct 43, an indoor air duct 44 and a fresh air duct. The outdoor air duct 43 and the indoor air duct 44 are arranged in a horizontal direction. The first fresh air duct 45 and the second fresh air duct 48 are located above the outdoor air duct 43 and the indoor air duct 44. The first fresh air duct 45 and the second fresh air duct 48 are separated from both the indoor air duct 44 and the outdoor air duct 43. The air duct support component 42 and the air duct cover component 41 can both be integrally molded parts.
[0103] Reference Figures 1-7 The casing 1 has an outdoor air inlet 1221, an outdoor air outlet 1222, an indoor air inlet 1211, an indoor air outlet 1212, a fresh air inlet 1223, a first fresh air outlet 1213, and a second fresh air outlet 1214. The outdoor air duct 43 connects the outdoor air inlet 1221 and the outdoor air outlet 1222. The indoor air duct 44 connects the indoor air inlet 1211 and the indoor air outlet 1212. The first fresh air duct 45 connects the fresh air inlet 1223 and the first fresh air outlet 1213. The second fresh air duct 48 connects the fresh air inlet 1223 and the second fresh air outlet 1214. After the window air conditioner 100 is installed on the window, the outdoor air inlet 1221, the outdoor air outlet 1222 and the fresh air inlet 1223 are connected to the outside, and the indoor air inlet 1211, the indoor air outlet 1212, the first fresh air outlet 1213 and the second fresh air outlet 1214 are connected to the inside.
[0104] Reference Figures 5-12The fan assembly includes an outdoor impeller 21, an indoor impeller 22, a first fresh air impeller 231, a second fresh air impeller 232, a first motor 24, and a second motor 25. The outdoor impeller 21 is located in the outdoor air duct 43 and is connected to the first motor 24. The indoor impeller 22 is located in the indoor air duct 44. The first fresh air impeller 231 is located in the first fresh air duct 45, and the second fresh air impeller 232 is located in the second fresh air duct 48. The first fresh air impeller 231 and the second fresh air impeller 232 are at least partially offset in the direction from indoors to outdoors. The outdoor impeller 21 and the first fresh air impeller 231 are both connected to the first motor 24, and the indoor impeller 22 and the second fresh air impeller 232 are both connected to the second motor 25. The rotation axes of both the outdoor impeller 21 and the indoor impeller 22 extend vertically. The first fresh air impeller 231 is located directly above the outdoor impeller 21 and is coaxially arranged with it. The second fresh air impeller 232 is located directly above the indoor impeller 22 and is coaxially arranged with it. Optionally, the first motor 24 and the second motor 25 can be dual-axis motors. The outdoor impeller 21 and the first fresh air impeller 231 are both connected to the two output shafts of the first motor 24, and the indoor impeller 22 and the second fresh air impeller 232 are respectively connected to the two output shafts of the second motor 25. Both the outdoor impeller 21 and the indoor impeller 22 can be cross-flow impellers, and the first fresh air impeller 231 and the second fresh air impeller 232 can also be cross-flow impellers. Optionally, the diameter of the first fresh air impeller 231 is equal to the diameter of the outdoor impeller 21, and the diameter of the second fresh air impeller 232 is equal to the diameter of the indoor impeller 22.
[0105] The cross-section of the casing 1 is roughly rectangular. The outdoor impeller 21 and the indoor impeller 22 are arranged roughly along the diagonal of the casing 1 in the horizontal direction. This makes the layout of the fan assembly more reasonable, reduces the space occupied by the fan assembly in the casing 1, and makes the structure of the window air conditioner 100 more compact.
[0106] Reference Figures 5-9 The fan assembly may also include a first bearing 26, a second bearing 27, a third bearing 28, and a fourth bearing 29. The first bearing 26 is fixed to the top wall of the outdoor air duct 43 and is adapted to the rotating shaft of the outdoor fan wheel 21. The fourth bearing 29 is fixed to the top wall of the first fresh air duct 45 and is adapted to the rotating shaft of the first fresh air fan wheel 231. When the first motor 24 drives the outdoor fan wheel 21 and the first fresh air fan wheel 231 to work, the rotating shaft of the outdoor fan wheel 21 can rotate within the first bearing 26, and the rotating shaft of the first fresh air fan wheel 231 can rotate within the third bearing 28. This can prevent the outdoor fan wheel 21 and the first fresh air fan wheel 231 from having a large offset during rotation, making the first motor 24 run more stably and the first fresh air fan wheel 231 and the outdoor fan wheel 21 rotate stably, thereby reducing the noise generated during the operation of the window air conditioner 100.
[0107] The second bearing 27 is fixed to the bottom wall of the indoor air duct 44 and is adapted to the rotating shaft of the indoor fan wheel 22. The third bearing 28 is fixed to the top wall of the second fresh air duct 48 and is adapted to the rotating shaft of the second fresh air fan wheel 232. When the second motor 25 drives the indoor fan wheel 22 and the second fresh air fan wheel 232 to work, the rotating shaft of the indoor fan wheel 22 can rotate within the second bearing 27, and the rotating shaft of the second fresh air fan wheel 232 can rotate within the third bearing 28. This can prevent the indoor fan wheel 22 and the second fresh air fan wheel 232 from having a large offset during rotation, making the second motor 25 run more stably and the indoor fan wheel 22 and the second fresh air fan wheel 232 rotate stably, thereby reducing the noise generated during the operation of the window air conditioner 100.

The first fresh air outlet 1213 is formed on the left side wall of the housing 1, and the second fresh air outlet 1214 is formed on the right side wall of the housing 1. The first fresh air outlet 1213 and the second fresh air outlet 1214 are staggered in the indoor-outdoor direction.
[0109] For example, adjustable fresh air guide vanes are provided at the first fresh air outlet 1213 and the second fresh air outlet 1214, and an adjustable indoor air outlet 1212 is provided with an indoor air outlet guide vane. When the window air conditioner 100 is working, the user can adjust the direction of fresh air blowing out from the first fresh air outlet 1213 and the second fresh air outlet 1214 by adjusting the angle of the fresh air guide vanes, and adjust the direction of indoor air blowing out from the indoor air outlet 1212 by adjusting the angle of the indoor air outlet guide vanes, thereby meeting different user needs and improving the overall performance of the window air conditioner 100.

The outdoor heat exchanger 31 is placed vertically and its cross-section extends in a straight line. The indoor heat exchanger 32 is located in the indoor air duct 44 and near the indoor air inlet 1211. The indoor heat exchanger 32 is mounted on the air duct cover member 41 and is horizontally positioned between the air duct cover member 41 and the front housing 121.
