Technical Field

[0002] The present disclosure relates to the technical field of air conditioning, and in particular to a window air conditioner. Background Art

[0003] In the relevant technology, the window air conditioner is a small air conditioner that can be installed on the window. Among the room air conditioner products, the window air conditioner is the earliest model. It has the advantages of simple structure, low production cost, low price, easy installation, and reliable operation. It accounts for a large proportion of applications in the market.

[0004] When a window air conditioner is installed on a window, its structural dimensions have a positive correlation with the difficulty of installation, that is, the larger the size, the higher the installation difficulty. Therefore, a miniaturized design of the window air conditioner is very necessary for its popularization. Summary of the Invention

[0005] The present disclosure aims to solve the problem of miniaturization design of window-type air conditioners.

[0006] In some aspects of the present disclosure, a window air conditioner is provided, comprising: a casing, an indoor heat exchanger, an indoor fan assembly, an outdoor heat exchanger and an outdoor fan assembly; the indoor heat exchanger is arranged in the casing; the indoor fan assembly is arranged in the casing, and the indoor fan assembly transports indoor air to the indoor heat exchanger for heat exchange and then outputs it to the room; the outdoor heat exchanger is arranged in the casing; the outdoor fan assembly is arranged in the casing, and the outdoor fan assembly transports outdoor air to the outdoor heat exchanger for heat exchange and then outputs it to the outside; the casing comprises: a base, an indoor shell and an outdoor shell, the indoor heat exchanger, the indoor fan assembly, the outdoor heat exchanger and the outdoor fan assembly are arranged on the base; the indoor shell is arranged on the base and covers the indoor heat exchanger and the indoor fan assembly; the outdoor shell is arranged on the base and covers the outdoor heat exchanger and the outdoor fan assembly, and the outdoor shell is connected to the indoor shell; wherein the top of the indoor shell is lower than the top of the outdoor shell, and a downwardly recessed avoidance groove is formed between the indoor shell and the outdoor shell, and the avoidance groove is used to avoid the bottom of the window.

[0007] Because the top of the indoor housing of this window air conditioner is lower than the top of the outdoor housing, the indoor housing can be made more compact, allowing the indoor heat exchanger and indoor fan assembly to be more compactly arranged within the indoor housing. Furthermore, because the top of the outdoor housing is higher than the top of the indoor housing, the outdoor housing's structural design allows for a larger air intake area, improving the performance of the outdoor heat exchanger and, consequently, the performance of the window air conditioner. The escape groove can be positioned opposite the window, allowing the window to be snapped onto the escape groove, thus making the window air conditioner's placement on the window more secure.

[0028] When a window air conditioner is installed on a window, its structural dimensions have a positive correlation with the difficulty of installation, that is, the larger the size, the higher the installation difficulty. Therefore, a miniaturized design of the window air conditioner is very necessary for its popularization.

[0029] As shown in Figures 1, 3, and 4, according to some embodiments of the present disclosure, a window air conditioner 10 is provided. When the window air conditioner 10 is arranged in an indoor environment, it is suitable to be built on a window 11. Since the window air conditioner 10 is arranged on the window 11, the arrangement of the window air conditioner 10 in the indoor environment can be more space-saving, thereby facilitating the arrangement of the window air conditioner 10 in the indoor environment. Allowing the window air conditioner 10 to be arranged on the window 11 can provide more reliable performance, can be applied to the indoor environment to meet user needs, and can improve the comfort of users using the window air conditioner 10.

[0030] As shown in Figures 1 and 5, in some embodiments, a window air conditioner 10 may include a housing 100. Housing 100 may provide assembly space. Housing 100 allows other components within window air conditioner 10 to be conveniently positioned within housing 100. Housing 100 protects these components, thereby enhancing the performance and lifespan of window air conditioner 10 during use.

[0031] In some embodiments, the window air conditioner 10 may include an indoor heat exchanger 200. The indoor heat exchanger 200 may be disposed within the housing 100. The indoor heat exchanger 200 may be configured to exchange heat with indoor airflow, allowing the heat-exchanged airflow to be applied to the indoor environment, thereby improving the user's experience in the indoor environment.

[0032] In some embodiments, the window air conditioner 10 may include an indoor fan assembly 300. The indoor fan assembly 300 may be disposed within the housing 100. The indoor fan assembly 300 may be used to introduce airflow into the room. The indoor fan assembly 300 may transport the indoor air to the indoor heat exchanger 200 for heat exchange before outputting the air back into the room.

[0033] In some embodiments, the window air conditioner 10 may include an outdoor heat exchanger 400. The outdoor heat exchanger 400 may be disposed within the housing 100. The outdoor heat exchanger 400 may be configured to exchange heat with outdoor air.

[0034] In some embodiments, the window air conditioner 10 may include an outdoor fan assembly 500. The outdoor fan assembly 500 may be disposed within the housing 100. The outdoor fan assembly 500 may be used to drive outdoor airflow into the window air conditioner 10. The outdoor fan assembly 500 may transport the outdoor air to the outdoor heat exchanger 400 for heat exchange before outputting the air outdoors.

[0035] In some embodiments, the window air conditioner 10 may include a housing 100, an indoor heat exchanger 200, an indoor fan assembly 300, an outdoor heat exchanger 400, and an outdoor fan assembly 500. In the structural arrangement of the window air conditioner 10, the window air conditioner 10 may include the housing 100, the indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500.

[0036] In some embodiments, during use of the window air conditioner 10, the refrigerant may circulate between the indoor heat exchanger 200 and the outdoor heat exchanger 400. The indoor airflow and the outdoor airflow exchange heat with the indoor heat exchanger 200 and the outdoor heat exchanger 400, respectively, allowing the refrigerant to have higher performance during the circulation process, thereby improving the performance of the window air conditioner 10 and enabling the window air conditioner 10 to better improve the indoor environment.

[0037] As shown in Figures 5 and 6, in some embodiments, the housing 100 may include a base 110. The indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500 may be disposed on the base 110, which may be used to provide support. The indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500 may be constructed on the base 110 to provide a more secure arrangement of the indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500 within the housing 100.

[0038] As shown in Figures 5 and 7, in some embodiments, the housing 100 may include an indoor casing 120. The indoor casing 120 may be disposed on the base 110. The indoor casing 120 may house the indoor heat exchanger 200 and the indoor fan assembly 300. The indoor heat exchanger 200 and the indoor fan assembly 300 may be constructed between the indoor casing 120 and the base 110, respectively.

[0039] As shown in Figures 5 and 8, in some embodiments, the housing 100 may include an outdoor housing 130. The outdoor housing 130 may be disposed on the base 110. The outdoor housing 130 may house the outdoor heat exchanger 400 and the outdoor fan assembly 500. The outdoor housing 130 may be connected to the indoor housing 120. The outdoor heat exchanger 400 and the outdoor fan assembly 500 may be constructed between the outdoor housing 130 and the base 110, respectively.

[0040] In some embodiments, during the construction of the casing 100, the base 110, the indoor shell 120 and the outdoor shell 130 can be constructed separately. This can simplify the construction process and allow the structure of the casing 100 to have higher performance. It can protect other structures in the window air conditioner 10 and increase the service life of the window air conditioner 10.

[0041] As shown in Figure 1, in some embodiments, the top of the indoor housing 120 can be lower than the top of the outdoor housing 130. During the arrangement of the indoor and outdoor housings 120, 130, the indoor housing 120 can be positioned inside the window 11, while the outdoor housing 130 can be positioned outside the window 11, allowing the window 11 to be snapped onto the housing 100. Since the top of the indoor housing 120 is lower than the top of the outdoor housing 130, the indoor housing 120 can be more compact, facilitating placement of the window air conditioner 10 on the window 11. Since the top of the outdoor housing 130 is higher than the top of the indoor housing 120, the air inlet of the outdoor housing 130 has a larger air intake area for introducing outdoor airflow. This allows the outdoor heat exchanger 400 to achieve higher heat exchange performance during use, thereby improving the performance of the window air conditioner 10.

[0042] In some embodiments, a downwardly recessed escape groove 101 may be formed between the indoor housing 120 and the outdoor housing 130. The escape groove 101 can be used to clear the lower edge of the window 11. By providing the recessed escape groove 101 between the indoor housing 120 and the outdoor housing 130, the escape groove 101 can be positioned opposite the window 11, allowing the window 11 to be snapped onto the escape groove 101, thereby providing a more secure placement of the window air conditioner 10 on the window 11.

[0043] According to some embodiments of the window air conditioner 10 of the present disclosure, since the top of the indoor housing 120 is lower than the top of the outdoor housing 130, the structural dimensions of the indoor housing 120 can be made more compact, and the indoor heat exchanger 200 and the indoor fan assembly 300 can be arranged more compactly within the indoor housing 120. Furthermore, since the top of the outdoor housing 130 is higher than the top of the indoor housing 120, the outdoor housing 130 can be structurally designed to have a larger air intake area, thereby improving the performance of the outdoor heat exchanger 400 and thus enhancing the performance of the window air conditioner 10 to meet user needs.

[0044] In some embodiments, the maximum vertical distance from the top of the indoor shell 120 to the base 110 may be h1. The maximum vertical distance from the top of the outdoor shell 130 to the base 110 may be h2. h1 and h2 may satisfy the relationship: h1 ≥ 0.5h2. The relative size relationship between the indoor shell 120 and the outdoor shell 130 should not be too small. If the ratio between the vertical height of the indoor shell 120 and the vertical height of the outdoor shell 130 is too small, the structure of the indoor shell 120 will be too small, thereby affecting the arrangement of the indoor heat exchanger 200 and the indoor fan assembly 300 in the indoor shell 120, resulting in relatively low performance of the indoor heat exchanger 200 and the indoor fan assembly 300, thereby affecting the performance of the window air conditioner 10.

[0045] In some embodiments, the maximum vertical distance from the top of the indoor housing 120 to the base 110 can be h1. The maximum vertical distance from the top of the outdoor housing 130 to the base 110 can be h2. h1 and h2 can satisfy the relationship: h1≤0.75h2. The relative size relationship between the indoor housing 120 and the outdoor housing 130 should not be too large. If the ratio between the vertical height of the indoor housing 120 and the vertical height of the outdoor housing 130 is too large, the air inlet area on the outdoor housing 130 will be insufficient, and the performance of the outdoor heat exchanger 400 cannot be effectively improved, thereby affecting the performance of the window air conditioner 10.

[0046] In some embodiments, the maximum vertical distance from the top of the indoor housing 120 to the base 110 may be h1. The maximum vertical distance from the top of the outdoor housing 130 to the base 110 may be h2. h1 and h2 may satisfy the relationship: 0.5h2≤h1≤0.75h2. The ratio between the vertical height of the indoor housing 120 and the vertical height of the outdoor housing 130 is set between 0.5 and 0.75, which can take into account the compact structure of the indoor housing 120 and the relatively high performance of the outdoor housing 130. This makes the arrangement process of the window air conditioner 10 on the window 11 simpler, the structure more reliable, and the performance is higher to improve the indoor environment.

[0047] 5 and 7 , in some embodiments, the indoor housing 120 includes an indoor ceiling 121. The indoor ceiling 121 may be located at a top area of ​​the indoor housing 120.

[0048] In some embodiments, the indoor top plate 121 may include a first top plate portion 122. The first top plate portion 122 may be constructed on the top of the indoor housing 120. The vertical height of the indoor housing 120 may be a relative distance between the first top plate portion 122 and the base 110.

[0049] In some embodiments, the indoor top plate 121 may include a third top plate portion 124. The first top plate portion 122 may be higher than the third top plate portion 124. The third top plate portion 124 may be located on a side of the first top plate portion 122 that is closer to the outdoor housing 130. The third top plate portion 124 may be used to connect to the outdoor housing 130.

[0050] In some embodiments, the indoor top plate 121 may include a second top plate portion 123. The second top plate portion 123 may be connected between the first top plate portion 122 and the third top plate portion 124. The second top plate portion 123 may be bent relative to the first top plate portion 122 and the third top plate portion 124. The second top plate portion 123 is connected to the first top plate portion 122 and the third top plate portion 124 in a relatively bent manner, so that the third top plate portion 124 can be constructed on the lower side of the first top plate portion 122, and the third top plate portion 124 can be set in a recessed manner under the second top plate portion 123, so as to form an avoidance groove 101 connected to the window 11. For example, the second top plate portion 123, the third top plate portion 124 and the outdoor shell 130 can be used together to form the avoidance groove 101, which not only makes the structural setting of the avoidance groove 101 more reliable, but also makes the clip-on setting of the window air conditioner 10 on the window 11 more stable, allowing the window air conditioner 10 to apply its performance to the indoor environment to improve the indoor environment.

[0051] In some embodiments, the second top plate portion 123 extends obliquely downward in the direction from the first top plate portion 122 toward the third top plate portion 124. The second top plate portion 123 extends obliquely downward in the direction from front to back. The direction of the casing 100 close to the indoors is the front, and the direction of the casing 100 close to the outdoors is the back. In this way, by allowing the second top plate portion 123 to extend obliquely downward in the direction from the first top plate portion 122 toward the third top plate portion 124, the third top plate portion 124 can be constructed on the lower side of the first top plate portion 122, so that the second top plate portion 123, the third top plate portion 124 and the outdoor shell 130 can form the avoidance groove 101, which can make the structure of the avoidance groove 101 more reliable, and the assembly setting of the window air conditioner 10 on the window 11 more reliable.

[0052] 5 and 8 , in some embodiments, the outdoor housing 130 may include an outdoor roof panel 131. The outdoor roof panel 131 may be constructed on the top of the outdoor housing 130. The vertical height of the outdoor housing 130 may be the relative distance between the outdoor roof panel 131 and the base 110.

[0053] In some embodiments, the outdoor housing 130 may include an outdoor side panel 132. The outdoor side panel 132 may be connected to both sides of the outdoor top panel 131. For example, two outdoor side panels 132 may be provided. The two outdoor side panels 132 may be connected to both sides of the outdoor top panel 131, and the two outdoor side panels 132 may be connected to the base 110.

[0054] In some embodiments, the outdoor housing 130 may include an outdoor front panel 133. The outdoor front panel 133 may be constructed on a side of the outdoor top panel 131 and the outdoor side panel 132 close to the indoor housing 120. The outdoor front panel 133 may be disposed between the outdoor top panel 131 and the two outdoor side panels 132. The outdoor front panel 133 may be connected to the outdoor top panel 131 and the outdoor side panels 132, respectively. The lower end of the outdoor front panel 133 may be connected to the third top panel portion 124, so that the second top panel portion 123, the third top panel portion 124 and the outdoor front panel 133 may together form an avoidance groove 101. In this way, the structural setting of the avoidance groove 101 may be made more reliable, the setting stability of the window air conditioner 10 on the window 11 may be made higher, and the window air conditioner 10 may provide higher performance.

[0055] As shown in Figures 5 and 8, in some embodiments, the outdoor housing 130 may include a lap plate 134. The lap plate 134 may be connected to the lower end of the outdoor front panel 133. The lap plate 134 may be bent relative to the outdoor front panel 133. The lap plate 134 may be overlapped on the third top plate portion 124. In this way, by providing the lap plate 134 at the lower end of the outdoor front panel 133, the lap plate 134 can provide a higher support effect on the outdoor front panel 133. The lap plate 134 can improve the structural strength of the outdoor front panel 133. The lap plate 134 can make the avoidance groove 101 constructed between the outdoor front panel 133 and the second top plate portion 123 and the third top plate portion 124 have higher structural strength and usability.

[0056] In some embodiments, the lap plate 134 may be disposed outside the third top plate portion 124. The lap plate 134 may be disposed over the top surface of the third top plate portion 124. In this way, the lap plate 134 may protect the third top plate portion 124, making the use of the third top plate portion 124 more reliable.

[0057] In some embodiments, at least a portion of the lap plate 134 and the third top plate 124 may overlap. This allows the lap plate 134 to improve the structural performance of the third top plate 124, providing the third top plate 124 with greater structural strength, thereby improving the performance of the avoidance groove 101 and making the attachment of the window air conditioner 10 to the window 11 more secure.

[0058] As shown in Figures 5 and 7, in some embodiments, the indoor housing 120 may include indoor side panels 125. The indoor side panels 125 may be connected to both sides of the indoor top panel 121. For example, two indoor side panels 125 may be provided. The two indoor side panels 125 may be connected to both sides of the indoor top panel 121, respectively. The two indoor side panels 125 may be connected to the base 110, respectively.

[0059] In some embodiments, the indoor housing 120 may include an indoor front panel 126. The indoor front panel 126 may be constructed on a side of the outdoor housing 130 that is away from the outdoor housing 130. The indoor front panel 126 may be located between the indoor top panel 121 and the two indoor side panels 125. The indoor front panel 126 may be connected to the indoor top panel 121 and the indoor side panels 125, respectively.

[0060] In some embodiments, the indoor housing 120 may include an indoor rear panel 127. The indoor rear panel 127 may be constructed on a side of the outdoor housing 130 adjacent to the outdoor housing 130. The indoor rear panel 127 may be located between the indoor top panel 121 and the two indoor side panels 125. The indoor rear panel 127 is connected to the indoor top panel 121 and the indoor side panels 125, respectively.

[0061] During the construction of the indoor shell 120, the indoor side panels 125 can be constructed on both sides of the indoor top panel 121, the indoor front panel 126 can be constructed on the front side of the indoor top panel 121 and the indoor side panels 125, and the indoor rear panel 127 can be constructed on the rear side of the indoor top panel 121 and the indoor side panels 125, thereby separating the indoor structural components from the outdoor structural components.

[0062] In some embodiments, the indoor rear panel 127 can be located below the outdoor front panel 133. By constructing the indoor rear panel 127 below the outdoor front panel 133, the avoidance groove 101 constructed between the indoor housing 120 and the outdoor housing 130 can have higher structural strength, making the connection setting of the window air conditioner 10 on the window 11 more reliable.

[0063] As shown in Figures 5 and 7, in some embodiments, the indoor housing 120 may include an indoor front housing 128 and an indoor rear housing 129. The indoor front housing 128 may include an indoor front panel 126, a front portion of the first top panel 122, and a front portion of the indoor side panel 125. The indoor rear housing 129 may include an indoor rear panel 127, a rear portion of the first top panel 122, a second top panel 123, a third top panel 124, and a rear portion of the indoor side panel 125. The front portion of the first top panel 122 may be connected to the rear portion of the first top panel 122. The front portion of the indoor side panel 125 may be connected to the rear portion of the indoor side panel 125. The indoor front housing 128 and the indoor rear housing 129 may facilitate the construction of the indoor housing 120. By constructing the indoor front shell 128 and the indoor rear shell 129 in a split manner, production efficiency can be improved, production costs can be reduced, and the indoor front shell 128 and the indoor rear shell 129 can have higher structural strength. The casing 100 can not only provide better protection performance to protect other structures in the window air conditioner 10, so that the window air conditioner 10 has higher performance, but also the casing 100 can have higher structural strength and be snap-connected to the window 11, so that the setting of the window air conditioner 10 on the window 11 can be more reliable.

[0064] As shown in FIG8 , in some embodiments, the outdoor side panel 132 may be provided with an extension panel 135 extending forward. The extension panel 135 may be connected to the lap plate 134. The extension panel 135 may be overlapped on the indoor side panel 125. The extension panel 135 may be provided with a sealing structure insertion groove 136. In this way, by connecting the extension panel 135 to the lap plate 134, the extension panel 135 can improve the structural strength of the lap plate 134, thereby improving the performance of the lap plate 134. By overlapping the extension panel 135 on the outside of the indoor side panel 125, the extension panel 135 can overlap with the indoor side panel 125, thereby making the structural setting of the casing 100 more reliable. In addition, by providing a plug-in slot 136 with a sealing structure on the extension plate 135, when the casing 100 is snapped onto the window 11, the window 11 and the plug-in slot 136 can be plugged and sealed, so that the sealing of the window air conditioner 10 on the window 11 can be improved, thereby allowing the window air conditioner 10 to provide more reliable performance.

[0065] In some embodiments, the outdoor front panel 133 may be provided with an outdoor front air inlet 137. The outdoor housing 130 may be configured with multiple air inlets. Specifically, the outdoor front panel 133 may be provided with multiple outdoor front air inlets 137. Multiple outdoor front air inlets 137 provide the outdoor housing 130 with a larger air inlet area, allowing the outdoor heat exchanger 400 to achieve higher heat exchange performance, thereby improving the performance of the window air conditioner 10 and enabling faster adjustment to improve the indoor environment.

[0066] In some embodiments, the outdoor top plate 131 may be provided with an outdoor top air inlet 138. The outdoor housing 130 may be configured with multiple air inlets. Specifically, the outdoor top plate 131 may be provided with multiple outdoor top air inlets 138. Multiple outdoor top air inlets 138 provide the outdoor housing 130 with a larger air intake area, allowing the outdoor heat exchanger 400 to achieve higher heat exchange performance, thereby improving the performance of the window air conditioner 10 and enabling faster adjustment to improve the indoor environment.

[0067] In some embodiments, the outdoor side panel 132 may be provided with an outdoor air inlet 139. The outdoor housing 130 is adapted to be provided with multiple air inlets. That is, the outdoor side panel 132 may be provided with multiple outdoor air inlets 139. Multiple outdoor air inlets 139 can provide the outdoor housing 130 with a larger air inlet area, allowing the outdoor heat exchanger 400 to have higher heat exchange performance, thereby improving the performance of the window air conditioner 10 and adjusting the indoor environment more quickly.

[0068] As shown in Figures 5 and 11, in some embodiments, the indoor heat exchanger 200 may include a first indoor heat exchanger 210 and a second indoor heat exchanger 220. The first indoor heat exchanger 210 may be connected to the second indoor heat exchanger 220. By connecting the first indoor heat exchanger 210 and the second indoor heat exchanger 220, the indoor airflow, after entering the housing 100, sequentially contacts and exchanges heat with the first indoor heat exchanger 210 and the second indoor heat exchanger 220. The airflow after heat exchange then enters the indoor environment, thereby improving the comfort of the indoor environment.

[0069] In some embodiments, the first indoor heat exchanger 210 can extend obliquely downward in the direction from indoors to outdoors. The first indoor heat exchanger 210 can extend obliquely downward in the direction from front to back. The direction of the first indoor heat exchanger 210 close to the indoors is the front, and the direction of the first indoor heat exchanger 210 close to the outdoors is the back. By extending the first indoor heat exchanger 210 obliquely downward in the direction from indoors to outdoors, the arrangement of the first indoor heat exchanger 210 in the casing 100 can be made more compact, the structural size of the window air conditioner 10 can be reduced, the production cost can be reduced, and the arrangement process of the window air conditioner 10 on the window 11 can be simpler and more reliable, so that the window air conditioner 10 can better improve the indoor environment.

[0070] In some embodiments, the second indoor heat exchanger 220 can extend obliquely downward in the direction from indoors to outdoors. The second indoor heat exchanger 220 extends obliquely upward in the direction from front to back. The direction of the second indoor heat exchanger 220 close to the indoors is the front, and the direction of the first indoor heat exchanger 210 close to the outdoors is the rear. By extending the second indoor heat exchanger 220 obliquely upward in the direction from indoors to outdoors, the arrangement of the second indoor heat exchanger 220 in the casing 100 can be made more compact, the structural size of the window air conditioner 10 can be reduced, the production cost can be reduced, and the arrangement process of the window air conditioner 10 on the window 11 can be simpler and more reliable, so that the window air conditioner 10 can better improve the indoor environment.

[0071] In some embodiments, the distance from the top to the bottom of the first indoor heat exchanger 210 can be greater than the distance from the top to the bottom of the second indoor heat exchanger 220. By making the distance from the top to the bottom of the first indoor heat exchanger 210 greater than the distance from the top to the bottom of the second indoor heat exchanger 220, the heat exchange area of ​​the first indoor heat exchanger 210 can be larger than the heat exchange area of ​​the second indoor heat exchanger 220, allowing the first indoor heat exchanger 210 to provide higher heat exchange performance, while the second indoor heat exchanger 220 can supplement the heat exchange performance of the airflow, thereby allowing the indoor airflow to more completely exchange heat with the first indoor heat exchanger 210 and the second indoor heat exchanger 220, thereby making the indoor airflow acting on the indoor environment more comfortable, allowing the indoor environment to be improved more quickly, and thus improving the performance of the window air conditioner 10.

[0072] In some embodiments, the window air conditioner 10 may include a housing 100, an indoor heat exchanger 200, an indoor fan assembly 300, an outdoor heat exchanger 400, and an outdoor fan assembly 500. The indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500 are disposed within the housing 100. The indoor fan assembly 300 is used to transport indoor air to the indoor heat exchanger 200 for heat exchange before outputting it indoors. The outdoor fan assembly 500 is used to transport outdoor air to the outdoor heat exchanger 400 for heat exchange before outputting it outdoors. The indoor heat exchanger 200 includes a first indoor heat exchanger 210 and a second indoor heat exchanger 220. The first indoor heat exchanger 210 is connected to the second indoor heat exchanger 220. The first indoor heat exchanger 210 extends obliquely downward from front to rear. The second indoor heat exchanger 220 extends obliquely upward from front to rear. A distance from an upper end to a lower end of the first indoor heat exchanger 210 is greater than a distance from an upper end to a lower end of the second indoor heat exchanger 220 .

[0073] According to the window air conditioner 10 of the embodiment of the present disclosure, by making the distance from the upper end to the lower end of the first indoor heat exchanger 210 greater than the distance from the upper end to the lower end of the second indoor heat exchanger 220, not only can the first indoor heat exchanger 210 and the second indoor heat exchanger 220 be arranged more compactly within the casing 100, thereby reducing the size of the window air conditioner 10, but also the first indoor heat exchanger 210 and the second indoor heat exchanger 220 can provide a larger heat exchange area, thereby allowing the indoor airflow to obtain better heat exchange when passing through the first indoor heat exchanger 210 and the second indoor heat exchanger 220, thereby improving the performance of the window air conditioner 10. In addition, due to the relatively small structural size of the window air conditioner 10, the window air conditioner 10 can be made compact, achieving a miniaturized design while also facilitating assembly and installation on the window 11, thereby improving assembly efficiency.

[0074] In some embodiments, after entering the housing 100, the indoor airflow may preferentially contact the first indoor heat exchanger 210 and then the second indoor heat exchanger 220. Thus, by preferentially contacting the first indoor heat exchanger 210, the first indoor heat exchanger 210 can provide a larger contact area, thereby enabling the first indoor heat exchanger 210 to provide greater heat exchange capacity, thereby improving the performance of the indoor heat exchanger 200 during use.

[0075] As shown in Figure 11, in some embodiments, the distance from the upper end to the lower end of the first indoor heat exchanger 210 can be h1. The distance from the upper end to the lower end of the second indoor heat exchanger 220 can be h2. h1 and h2 can satisfy the relationship: h2≤0.5h1. By setting h2≤0.5h1, the distance from the upper end to the lower end of the first indoor heat exchanger 210 can be greater than twice the distance from the upper end to the lower end of the second indoor heat exchanger 220. This not only allows the first indoor heat exchanger 210 to have a larger heat exchange area for heat exchange, but also facilitates the compact arrangement of the first indoor heat exchanger 210 and the second indoor heat exchanger 220, so that the structural arrangement of the window air conditioner 10 can be more miniaturized.

[0076] As shown in FIG. 11 , in some embodiments, the heat exchange tubes within the first indoor heat exchanger 210 can be arranged in rows a along the thickness of the first indoor heat exchanger 210. The heat exchange tubes within the second indoor heat exchanger 220 can be arranged in rows b along the thickness of the second indoor heat exchanger 220. The values ​​a and b can satisfy the relationship: a>b. Thus, by having the heat exchange tubes within the first indoor heat exchanger 210 have a greater thickness than the heat exchange tubes within the second indoor heat exchanger 220, the first indoor heat exchanger 210 can have a larger heat exchange area than the second indoor heat exchanger 220. This allows for higher heat exchange performance during use of the first indoor heat exchanger 210 and a more compact structure for the second indoor heat exchanger 220. This further allows for a more compact arrangement of the first and second indoor heat exchangers 210, 220 within the casing 100, simplifies and reliably facilitates the placement of the window air conditioner 10 on the window 11, and enables the window air conditioner 10 to provide higher heat exchange performance, thereby improving the indoor environment.

[0077] As shown in Figures 5 and 6, in other embodiments, the housing 100 may include a base 110, an indoor heat exchanger 200, an indoor fan assembly 300, an outdoor heat exchanger 400, and an outdoor fan assembly 500. The indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500 may be disposed on the base 110. The window air conditioner 10 may further include a water tray 600. The water tray 600 may be disposed on the base 110. The water tray 600 may be located below the rear end of the first indoor heat exchanger 210 and the front end of the second indoor heat exchanger 220, that is, the water tray 600 may be located below the bottom end of the first indoor heat exchanger 210 and the bottom end of the second indoor heat exchanger 220. In this way, by providing a water collecting pan 600 below the first indoor heat exchanger 210 and the second indoor heat exchanger 220, the condensed water generated by the first indoor heat exchanger 210 and the second indoor heat exchanger 220 during heat exchange can flow along the extension direction of the first indoor heat exchanger 210 and the second indoor heat exchanger 220 and flow into the relatively arranged water collecting pan 600 for collection.

[0078] In some embodiments, the base 110 may be formed with a water tank 111 below the outdoor fan assembly 500 and the outdoor heat exchanger 400. The water receiving tray 600 may have a drain nozzle 610. The drain nozzle 610 may extend above the water tank 111. Thus, by providing the water tank 111 on the base 110, condensed water generated by the first indoor heat exchanger 210 and the second indoor heat exchanger 220 during heat exchange can flow along the extension direction of the first indoor heat exchanger 210 and the second indoor heat exchanger 220, flow into the oppositely arranged water receiving tray 600 for collection, and then enter the water tank 111 through the drain nozzle 610, so that the collected condensed water can be subsequently processed uniformly. For example, when the outdoor heat exchanger 400 exchanges heat with the outdoor airflow, the generated hot airflow can evaporate the condensed water in the water tank 111, and the water vapor from the evaporated condensed water can be dissipated to the outside.

[0079] As shown in Figures 5, 7, and 9, in other embodiments, the housing 100 may include an indoor housing 120 and an outdoor housing 130. The indoor housing 120 may be mounted on the base 110 and house the indoor heat exchanger 200 and the indoor fan assembly 300. The indoor heat exchanger 200 and the indoor fan assembly 300 may be respectively constructed between the indoor housing 120 and the base 110. The outdoor housing 130 may be mounted on the base 110 and house the outdoor heat exchanger 400 and the outdoor fan assembly 500. The outdoor heat exchanger 400 and the outdoor fan assembly 500 may be respectively constructed between the outdoor housing 130 and the base 110. The outdoor housing 130 may be connected to the indoor housing 120. The indoor housing 120 may be provided with a through hole 1211. The drain nozzle 610 may pass through the through hole 1211 and extend into the space enclosed by the outdoor housing 130.

[0080] In this way, during the construction process of the casing 100, the base 110, the indoor shell 120 and the outdoor shell 130 can be constructed separately, thereby simplifying the construction process. The structure of the casing 100 can also have higher performance to protect other structures in the window air conditioner 10, thereby improving the service life of the window air conditioner 10.

[0081] At the same time, by providing a through hole 1211 in the indoor housing 120, the through hole 1211 is adapted to be disposed opposite the drain nozzle 610, allowing the drain nozzle 610 to enter the outdoor housing 130, thereby draining the condensed water from the water receiving pan 600 and collecting it in the water tank 111. In this way, the drainage of condensed water in the window air conditioner 10 can be made more reliable.

[0082] As shown in Figures 5, 9, and 10, in other embodiments, a first support base 620 may be provided on the water receiving tray 600. Two first support bases 620 may be provided. The two first support bases 620 may be located on the left and right sides of the front edge of the water receiving tray 600, respectively. The two first support bases 620 may be supported on the left and right sides of the first indoor heat exchanger 210, respectively. In this way, by providing the first support base 620 on the water receiving tray 600 and using the first support base 620 to support the first indoor heat exchanger 210, the first indoor heat exchanger 210 can be more securely arranged on the water receiving tray 600.

[0083] In some embodiments, the water tray 600 may be provided with a second support base 630, and two second support bases 630 may be provided. The two second support bases 630 may be located on the left and right sides of the rear edge of the water tray 600, respectively. The two second support bases 630 may support the left and right sides of the second indoor heat exchanger 220, respectively. Thus, by providing the second support base 630 on the water tray 600 and supporting the second indoor heat exchanger 220, the second indoor heat exchanger 220 can be more securely positioned on the water tray 600.

[0084] Furthermore, the use of the first support base 620 to support the first indoor heat exchanger 210 and the second support base 630 to support the second indoor heat exchanger 220 allows condensation to occur on the first and second indoor heat exchangers 210, 220, and allows the condensed water to flow along the first and second support bases 620, 630, and ultimately collect in the water collection pan 600. This allows the indoor airflow passing through the first and second indoor heat exchangers 210, 220 to be purified. As shown in Figures 5, 9, and 10, in other embodiments, the water collection pan 600 can be spaced apart from the base 110 in the vertical direction. An air inlet channel 640 can be formed between the water collection pan 600 and the base 110. The outlet of the air inlet channel 640 can be located below the second indoor heat exchanger 220. Thus, by forming the air inlet channel 640 between the water tray 600 and the base 110, indoor air can circulate through the air inlet channel 640. Since the outlet of the air inlet channel 640 is located below the second indoor heat exchanger 220, the indoor air can contact and exchange heat with the second indoor heat exchanger 220 after passing through the air inlet channel 640. This allows the indoor air to improve the indoor environment before entering the indoor environment, thereby improving the performance of the window air conditioner 10 during use.

[0085] As shown in FIG5 and FIG7, in some embodiments, a first indoor air inlet 112 may be formed on the front side of the indoor housing 120. An air outlet 113 may be formed on the front side of the indoor housing 120. During use, the indoor heat exchanger 200 can introduce indoor airflow through the first indoor air inlet 112, so that the indoor airflow can exchange heat with the indoor heat exchanger 200. The indoor fan assembly 300 can pass the heat-exchanged airflow through the air outlet 113.

[0086] As shown in Figures 5, 6, 7, and 10, in some embodiments, a second indoor air inlet 114 may be formed on the front side of the base 110. The first indoor air inlet 112 and the second indoor air inlet 114 may be respectively connected to the air inlet channel 640. In this way, by providing the first indoor air inlet 112 and the second indoor air inlet 114 at the air inlet end of the air inlet channel 640, the indoor heat exchanger 200 can introduce indoor airflow through the first indoor air inlet 112 and the second indoor air inlet 114 during use, thereby allowing the indoor airflow to better enter the indoor housing 120 for heat exchange with the indoor heat exchanger 200, thereby improving the working efficiency of the window air conditioner 10 during use, thereby allowing the indoor environment to be improved more quickly.

[0087] As shown in Figures 5 and 10, in some embodiments, the bottom of the water tray 600 can be provided with multiple support ribs 650. The multiple support ribs 650 can be supported by the base 110 and extend in the front-to-back direction. In this way, by providing multiple support ribs 650 on the water tray 600 and utilizing the multiple support ribs 650 to be arranged at intervals, the support ribs 650 can enhance the structural strength of the base 110, thereby enhancing the support effect of the base 110 for the indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500. In addition, the multiple support ribs 650 can also provide a diversion effect, allowing airflow to circulate under the guidance of the support ribs 650, thereby allowing airflow to circulate in the direction of the extension of the support ribs 650 and perform heat exchange, thereby improving the performance of the window air conditioner 10 during use.

[0088] As shown in Figures 5 and 9, in other embodiments, the water receiving tray 600 may include a base plate 660, a front water baffle 670, and a rear water baffle 680. The front water baffle 670 may be connected to the front edge of the base plate 660. The front water baffle 670 may extend downwardly in a direction from front to rear. The rear water baffle 680 may be connected to the rear edge of the base plate 660. The rear water baffle 680 may extend upwardly in a direction from front to rear.

[0089] Thus, by connecting the front water baffle 670 to the front side of the bottom plate 660 and extending obliquely downward from the front to the rear, and by connecting the rear water baffle 680 to the rear side of the bottom plate 660 and extending obliquely upward from the front to the rear, the front water baffle 670 and the rear water baffle 680 can be arranged according to the flow and collection direction of condensed water, thereby making the condensed water collection process more reliable. The condensed water can also be better collected in the water receiving tray 600 for subsequent use, making the airflow circulating in the window air conditioner 10 purer, thereby improving the indoor environment and enhancing the user's comfort in the indoor environment.

[0090] Other structures and operations of the window air conditioner 10 according to the embodiment of the present disclosure are well known to those skilled in the art and will not be described in detail here.

[0091] Those skilled in the art will understand that the scope of the present disclosure is not limited to the specific embodiments described above, and that certain elements of the embodiments may be modified and replaced without departing from the spirit of the present application. The scope of the present application is limited by the appended claims.
