When the window air conditioner is installed on the window, its structural size has a positive correlation with the installation difficulty, that is, the larger the size, the higher the installation difficulty. Therefore, the miniaturization design of the window air conditioner is essential for the popularization of the window air conditioner.

As shown in FIGS. 1, 3, and 4, according to some embodiments of the present disclosure, there is provided a window air conditioner 10. The window air conditioner 10 is adapted to be installed on a window 11 when the window air conditioner 10 is arranged in an indoor environment. 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, which facilitates the arrangement of the window air conditioner 10 in the indoor environment. The window air conditioner 10 can be arranged on the window 11, which can provide more reliable service performance, can be applied to the indoor environment to meet the needs of the user, and can improve the comfort of the user using the window air conditioner 10.

As shown in FIGS. 1, 2, and 5, in some embodiments, the window air conditioner 10 may include a casing 100. The casing 100 may be used to provide an assembly space. The casing 100 allows other structures within the window air conditioner 10 to be arranged within the casing 100. The casing 100 can protect other structures, thereby allowing the window air conditioner 10 to have higher service performance and service life during use.

In some embodiments, the window air conditioner 10 may include an indoor heat exchanger 200. The indoor heat exchanger 200 may be disposed in the casing 100. The indoor heat exchanger 200 can be used to exchange heat with the indoor airflow to allow the airflow after the heat exchange to act on the indoor environment to improve the user's experience in the indoor environment.

In some embodiments, the window air conditioner 10 may include an indoor fan assembly 300. The indoor fan assembly 300 may be disposed in the casing 100. The indoor fan assembly 300 may be used to introduce indoor airflow. The indoor fan assembly 300 may deliver the indoor air to the indoor heat exchanger 200 for heat exchange and then output the indoor air to the room.

In some embodiments, the window air conditioner 10 may include an outdoor heat exchanger 400. The outdoor heat exchanger 400 may be disposed in the casing 100. The outdoor heat exchanger 400 may be used to exchange heat with the outdoor airflow.

In some embodiments, the window air conditioner 10 may include an outdoor fan assembly 500. The outdoor fan assembly 500 may be disposed in the casing 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 deliver outdoor air to the outdoor heat exchanger 400 for heat exchange and then output the outdoor air to the outdoor.

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

In some embodiments, the refrigerant may circulate between the indoor heat exchanger 200 and the outdoor heat exchanger 400 during use of the window air conditioner 10. The indoor airflow and the outdoor airflow exchange heat with the indoor heat exchanger 200 and the outdoor heat exchanger 400, respectively, which allows the refrigerant to perform more efficiently during circulation, enhances the operating performance of the window air conditioner 10, and enables the window air conditioner 10 to better improve the indoor environment.

As shown in FIGS. 5 and 6, in some embodiments, the casing 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, and the base 110 may be used to provide a support function. The indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500 can be constructed on the base 110 to make the arrangement of the indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500 in the casing 100 more reliable.

As shown in FIGS. 5 and 7, in some embodiments, the casing 100 may include an indoor housing 120. The indoor housing 120 may be disposed on the base 110. The indoor housing 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 correspondingly be constructed between the indoor housing 120 and the base 110.

As shown in FIGS. 5 and 8, in some embodiments, the casing 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 correspondingly be constructed between the outdoor housing 130 and the base 110.

In some embodiments, during the construction process of the casing 100, the base 110, the indoor housing 120, and the outdoor housing 130 can be separately constructed, which can simplify the construction process, enable the structure of the casing 100 to exhibit superior performance, protect other structures in the window air conditioner 10, and improve the service life of the window air conditioner 10.

As shown in FIG. 1, in some embodiments, the top of the indoor housing 120 may be lower than the top of the outdoor housing 130. During the arrangement of the indoor housing 120 and the outdoor housing 130, the indoor housing 120 may be constructed on the inside of the window 11, and the outdoor housing 130 may be constructed on the outside of the window 11 so that the window 11 is adapted to be snapped on the casing 100. Since the top of the indoor housing 120 is lower than the top of the outdoor housing 130, the structure of the indoor housing 120 can be made more compact, thereby facilitating the arrangement 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 can have a larger air inlet area to introduce outdoor airflow, which allows the outdoor heat exchanger 400 to achieve higher heat exchange performance during operation, thereby enhancing the overall performance of the window air conditioner 10.

In some embodiments, an avoiding groove 101 recessed towards the base may be formed between the indoor housing 120 and the outdoor housing 130. The avoiding groove 101 may be used to avoid the lower edge of the window 11. By providing a recessed avoiding groove 101 between the indoor housing 120 and the outdoor housing 130, the avoiding groove 101 can be arranged opposite to the window 11, enabling the window 11 to be snapped on the avoiding groove 101, thereby making the arrangement of the window air conditioner 10 on the window 11 more reliable.

With the window air conditioner 10 according to some embodiments of the present disclosure, since the top of the indoor housing 120 is lower than the top of the outdoor housing 130, the structural size of the indoor housing 120 can be made smaller, and the arrangement of the indoor heat exchanger 200 and the indoor fan assembly 300 in the indoor housing 120 can be more compact. At the same time, since the top of the outdoor housing 130 is higher than the top of the indoor housing 120, the outdoor housing 130 can have a larger air inlet area in the structural design, and the use performance of the outdoor heat exchanger 400 can be improved, so that the use performance of the window air conditioner 10 can be higher to meet the needs of users.

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

In some embodiments, the vertical maximum distance from the top of the indoor housing 120 to the base 110 may be h1, the vertical maximum distance from the top of the outdoor housing 130 to the base 110 may be h2, where h1 and h2 may satisfy the relation: h1≤0.75 h2. The relative dimensional 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 use performance of the outdoor heat exchanger 400 will not be better improved, thereby affecting the use performance of the window air conditioner 10.

In some embodiments, the vertical maximum distance from the top of the indoor housing 120 to the base 110 may be h1, and the vertical maximum distance from the top of the outdoor housing 130 to the base 110 may be h2, where h1 and h2 may satisfy the relation: 0.5 h2≤h1≤0.75 h2. 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 balances the structural compactness of the indoor housing 120 with the relatively higher performance of the outdoor housing 130, making the installation process of the window air conditioner 10 on the window 11 simpler, the structure more reliable, and enhancing its performance to improve the indoor environment.

As shown in FIGS. 5 and 7, in some embodiments, the indoor housing 120 includes an indoor top plate 121. The indoor top plate 121 may be located in a top region of the indoor housing 120.

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 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.

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 close to the outdoor housing 130. The third top plate portion 124 may be used for connection with the outdoor housing 130.

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 provided to 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, allowing the third top plate portion 124 to be constructed on the lower side of the first top plate portion 122, allowing the third top plate portion 124 to be recessed under the second top plate portion 123, and an avoiding groove 101 that is configured to connect to the window 11 is formed. For example, the second top plate portion 123, the third top plate portion 124, and the outdoor housing 130 may be used to form the avoiding groove 101 together, which not only makes the structural setting of the avoiding groove 101 more reliable, but also enables the window air conditioner 10 to be snapped on the window 11 stably, and allows the window air conditioner 10 to apply the usage performance to the indoor environment to improve the indoor environment.

In some embodiments, the second top plate portion 123 extends obliquely downwards in a direction from the first top plate portion 122 towards the third top plate portion 124. The second top plate portion 123 extends downwards obliquely in a front-to-rear direction. Here, the direction of the casing 100 approaching the indoor is defined as the front, and the direction of the casing 100 approaching the outdoor is defined as the rear. As described above, by having the second top plate portion 123 extend obliquely downwards from the first top plate portion 122 towards 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, which allows the second top plate portion 123, the third top plate portion 124 and the outdoor housing 130 to form the avoiding groove 101, making the structure of the avoiding groove 101 more reliable, and ensuring the assembly and installation of the window air conditioner 10 on the window 11 to be reliable.

As shown in FIGS. 5 and 8, in some embodiments, the outdoor housing 130 may include an outdoor top plate 131. The outdoor top plate 131 may be constructed on top of the outdoor housing 130. The vertical height of the outdoor housing 130 may be the relative distance between the outdoor top plate 131 and the base 110.

In some embodiments, the outdoor housing 130 may include outdoor side plates 132. The outdoor side plates 132 may be connected to both sides of the outdoor top plate 131. For example, two outdoor side plates 132 may be provided. The two outdoor side plates 132 may be connected to both sides of the outdoor top plate 131, respectively, and the two outdoor side plates 132 may be connected to the base 110, respectively.

In some embodiments, the outdoor housing 130 may include an outdoor front plate 133. The outdoor front plate 133 may be constructed on the side of the outdoor top plate 131 and the outdoor side plates 132 close to the indoor housing 120. The outdoor front plate 133 may be located between the outdoor top plate 131 and the two outdoor side plates 132. The outdoor front plate 133 may be connected to the outdoor top plate 131 and the outdoor side plates 132, respectively. The lower end of the outdoor front plate 133 may be connected to the third top plate portion 124. The second top plate portion 123, the third top plate portion 124, and the outdoor front plate 133 may form the avoiding groove 101 together. This makes the configuration of the avoiding groove 101 more reliable, enhances the installation stability of the window air conditioner 10 on the window 11, and improves the use performance of the window air conditioner 10.

As shown in FIGS. 5 and 8, in some embodiments, the outdoor housing 130 may include a lap plate 134. The lap plate 134 may be connected to a lower end of the outdoor front plate 133. The lap plate 134 may be disposed bent relative to the outdoor front plate 133. The lap plate 134 may overlap the third top plate portion 124. In this way, by providing the lap plate 134 at the lower end of the outdoor front plate 133, the lap plate 134 can provide enhanced support for the outdoor front plate 133. The overlap plate 134 can improve the structural strength of the outdoor front plate 133. The lap plate 134 allows the avoiding groove 101 formed among the outdoor front plate 133, the second top plate portion 123 and the third top plate portion 124 to have higher structural strength and performance.

In some embodiments, the lap plate 134 may be disposed outside the third top plate portion 124. The lap plate 134 may be overlapped above the top surface of the third top plate portion 124. This arrangement allows the lap plate 134 to protect the third top plate portion 124, ensuring reliable use of the third top plate portion 124.

In some embodiments, at least a portion of the lap plate 134 and the third top plate portion 124 may overlap. In this way, the lap plate 134 can be adapted to correspondingly improve the structural performance of the third top plate portion 124, and the third top plate portion 124 can have higher structural strength, so that the use performance of the avoiding groove 101 can be correspondingly improved, and the window air conditioner 10 can be snapped on the window 11 reliably.

As shown in FIGS. 5 and 7, in some embodiments, the indoor housing 120 may include indoor side plates 125. The indoor side plates 125 may be connected to both sides of the indoor top plate 121. For example, two indoor side plates 125 may be provided. The two indoor side plates 125 may be connected to two sides of the indoor top plate 121, respectively. The two indoor side plates 125 may be connected to the base 110, respectively.

In some embodiments, the indoor housing 120 may include an indoor front plate 126. The indoor front plate 126 may be constructed on a side of the outdoor housing 130 away from the outdoor housing 130. The indoor front plate 126 may be located between the indoor top plate 121 and the two indoor side plates 125. The indoor front plate 126 may be connected to the indoor top plate 121 and the indoor side plates 125, respectively.

In some embodiments, the indoor housing 120 may include an indoor rear plate 127. The indoor rear plate 127 may be constructed on a side of the outdoor housing 130 proximate to the outdoor housing 130. The indoor rear plate 127 may be located between the indoor top plate 121 and the two indoor side plates 125. The indoor rear plate 127 is connected to the indoor top plate 121 and the indoor side plates 125, respectively.

In the construction process of the indoor housing 120, the indoor side plates 125 may be constructed on two sides of the indoor top plate 121, the indoor front plate 126 may be constructed on the front side of the indoor top plate 121 and the indoor side plates 125, and the indoor rear plate 127 may be constructed on the rear side of the indoor top plate 121 and the indoor side plates 125, thereby separating the indoor structural components from the outdoor structural components.

In some embodiments, the indoor rear plate 127 may be located below the outdoor front plate 133. By constructing the indoor rear plate 127 below the outdoor front plate 133, the avoiding groove 101 formed between the indoor housing 120 and the outdoor housing 130 can have higher structural strength, ensuring more secure installation of the window air conditioner 10 on the window 11.

As shown in FIGS. 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 plate 126, a front portion of the first top plate portion 122, and a front portion of the indoor side plates 125. The indoor rear housing 129 may include an indoor rear plate 127, a rear portion of the first top plate portion 122, a second top plate portion 123, a third top plate portion 124, and a rear portion of the indoor side plates 125. Here, the front portion of the first top plate portion 122 may be connected to the rear portion of the first top plate portion 122. The front portion of the indoor side plates 125 may be connected to the rear portion of the indoor side plates 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 housing 128 and indoor rear housing 129 as separate components, production efficiency can be improved, production costs can be reduced, and the structural strength of the indoor front housing 128 and indoor rear housing 129 can be enhanced. This allows the casing 100 to not only provide better protective properties to protect other structures within the window air conditioner 10, so as to allow for higher usability of the window air conditioner 10, but also allows the casing 100 to have higher structural strength to be snapped on the window 11, which can allow for a more reliable arrangement of the window air conditioner 10 on the window 11.

As shown in FIG. 8, in some embodiments, the outdoor side plates 132 may be provided with extension plates 135 extending forward. The extension plates 135 may be connected to the lap plate 134. The extension plates 135 may overlap the indoor side plates 125. The extension plates 135 may be provided with an insertion slot 136 with a sealing structure. In this way, by connecting the extension plates 135 to the lap plate 134, the extension plates 135 can improve the structural strength of the lap plate 134, and the usability of the lap plate 134 can be improved. Since the extension plates 135 overlap outside the indoor side plates 125, the extension plates can be overlapped with the indoor side plates 125, and the structural installation of the casing 100 can be more reliable. Additionally, by providing the insertion slot 136 with a sealing structure on the extension plates 135, when the casing 100 is installed on the window 11, the window 11 can be inserted into the slots for a tight seal with the insertion slots 136, improving the sealing performance of the window air conditioner 10 on the window 11, enabling the window air conditioner 10 to provide more reliable usage performance.

In some embodiments, an outdoor front air inlet 137 may be provided on the outdoor front plate 133. The outdoor housing 130 is adapted to have a plurality of air inlets constructed thereon. That is, a plurality of outdoor front air inlets 137 may be provided on the outdoor front plate 133. The plurality of outdoor front air inlets 137 can allow the outdoor housing 130 to have a larger air inlet area, improving the heat exchange performance of the outdoor heat exchanger 400, and enhancing the overall performance of the window air conditioner 10 for faster indoor environment adjustment.

Due to the fact that the top of the indoor housing is lower than that of the outdoor housing, the window air conditioner allows for a more compact design of the indoor housing, and the indoor heat exchanger and the indoor fan assembly are more compactly arranged within the indoor housing. Furthermore, since the top of the outdoor housing is higher than the top of the indoor housing, the outdoor housing can have a larger air inlet area in structural design, the use performance of the outdoor heat exchanger can be improved, leading to the improved operating performance of the window air conditioner. The avoiding groove can be arranged opposite to the window, allowing the window to be snapped on the avoiding groove. This design makes the installation of the window air conditioner on the window more reliable.

In some embodiments, an outdoor top air inlet 138 may be provided on the outdoor top plate 131. The outdoor housing 130 is adapted to have a plurality of air inlets constructed thereon. That is, a plurality of outdoor top air inlets 138 may be provided on the outdoor top plate 131. The plurality of outdoor top air inlets 138 can allow the outdoor housing 130 to have a larger air inlet area, improving the heat exchange performance of the outdoor heat exchanger 400, and enhancing the overall performance of the window air conditioner 10 for faster indoor environment adjustment.

In some embodiments, an outdoor side air inlet 139 may be provided on the outdoor side plates 132. The outdoor housing 130 is adapted to have a plurality of air inlets constructed thereon. That is, the outdoor side plates 132 may be provided with a plurality of outdoor side air inlets 139. The plurality of outdoor side air inlets 139 can allow the outdoor housing 130 to have a larger air inlet area, improving the heat exchange performance of the outdoor heat exchanger 400, and enhancing the operating performance of the window air conditioner 10 for faster indoor environment adjustment.

As shown in FIGS. 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. Thus, the connection of the first indoor heat exchanger 210 to the second indoor heat exchanger 220 allows indoor airflow to sequentially contact the first indoor heat exchanger 210 and the second indoor heat exchanger 220 after entering the casing 100, exchanging heat before being discharged into the indoor environment to improve indoor comfort.

In some embodiments, the first indoor heat exchanger 210 may be obliquely disposed relative to the base 110. For example, the first indoor heat exchanger 210 may extend obliquely downwards in a direction from the indoor towards the outdoor. The first indoor heat exchanger 210 may extend obliquely downwards in a front-to-rear direction. Here, the direction of the first indoor heat exchanger 210 approaching the indoor side is the front, and the direction of the first indoor heat exchanger 210 approaching the outdoor side is the rear. The first indoor heat exchanger 210 obliquely downwards in the direction from the indoor side to the outdoor side. This arrangement allows the first indoor heat exchanger 210 to be more compactly arranged within the casing 100, reducing the structure size of the window air conditioner 10, lowering production costs, and simplifying and securing the installation of the window air conditioner 10 on the window 11, so that the window air conditioner 10 can better improve the indoor environment.

In some embodiments, the second indoor heat exchanger 220 may be obliquely disposed relative to the base 110, and the first indoor heat exchanger 210 is oblique to the second indoor heat exchanger 220. For example, the second indoor heat exchanger 220 may extend obliquely downwards in a direction from the indoor side towards the outdoor side. The second indoor heat exchanger 220 extends obliquely upwards in a front-to-rear direction. Here, the direction of the second indoor heat exchanger 220 approaching the indoor side is the front, and the direction of the second indoor heat exchanger 220 approaching the outdoor side is the rear. The second indoor heat exchanger 220 obliquely downwards in the direction from the indoor side to the outdoor side. This arrangement allows the second indoor heat exchanger 220 to be more compactly arranged within the casing 100, reducing the structure size of the window air conditioner 10, lowering production costs, and simplifying and securing the installation of the window air conditioner 10 on the window 11, so that the window air conditioner 10 can better improve the indoor environment.

In some embodiments, a distance from the upper end to the lower end of the first indoor heat exchanger 210 may be greater than a distance from the upper end to the lower end of the second indoor heat exchanger 220. The distance from the upper end to the lower end of the first indoor heat exchanger 210 is larger than the distance from the upper end to the lower end of the second indoor heat exchanger 220. This allows the first indoor heat exchanger 210 to have a larger heat exchange area than the second indoor heat exchanger 220, and the first indoor heat exchanger 210 can provide higher heat exchange performance. The second indoor heat exchanger 220 can supplement the heat exchange performance for airflow, ensuring more complete heat exchange for the indoor airflow with the first indoor heat exchanger 210 and the second indoor heat exchanger 220, resulting in indoor airflow that has a higher level of comfort for the indoor environment. This enables the indoor environment to be improved more rapidly, thereby enhancing the performance of the window air conditioner 10.

In some embodiments, the window air conditioner 10 may include a casing 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 arranged in the casing 100. The indoor fan assembly 300 delivers the indoor air to the indoor heat exchanger 200 for heat exchange and then output the indoor air to the room. The outdoor fan assembly 500 delivers outdoor air to the outdoor heat exchanger 400 for heat exchange and then output the outdoor air to the outdoor. 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 downwards in a front-to-rear direction. The second indoor heat exchanger 220 extends obliquely upwards in a front-to-rear direction. A distance from the upper end to the lower end of the first indoor heat exchanger 210 is greater than a distance from the upper end to the lower end of the second indoor heat exchanger 220.

According to the window air conditioner 10 in the embodiment of the present disclosure, by having the distance from the upper end to the lower end of the first indoor heat exchanger 210 greater than that of the second indoor heat exchanger 220, the first indoor heat exchanger 210 and the second indoor heat exchanger 220 can be more compactly arranged within the casing 100, reducing the size of the window air conditioner 10, and the first indoor heat exchanger 210 and the second indoor heat exchanger 220 can provide a larger heat exchange area, resulting in better heat exchange when the indoor airflow passes through the first indoor heat exchanger 210 and the second indoor heat exchanger 220, allowing the airflow acting on the indoor environment to have higher performance for more rapid improvement of the indoor environment, thereby enhancing the performance of the window air conditioner 10. In addition, since the structural size of the window air conditioner 10 is relatively small, the structure of the window air conditioner 10 can be made compact, while realizing a miniaturized design, it is also possible to facilitate the assembly setup on the window 11, and improve the assembly efficiency.

In some embodiments, the indoor airflow may preferentially contact the first indoor heat exchanger 210 and then contact the second indoor heat exchanger 220 after entering the casing 100. In this way, by preferentially contacting the indoor air with the first indoor heat exchanger 210, the first indoor heat exchanger 210 can provide a larger contact area. This allows the first indoor heat exchanger 210 to provide a larger heat exchange capacity, and enhances the use performance of the indoor heat exchanger 200 during use.

As shown in FIG. 11, in some embodiments, the distance from the upper end to the lower end of the first indoor heat exchanger 210 may be h1. The distance from the upper end to the lower end of the second indoor heat exchanger 220 may be h2. h1 and h2 can satisfy the relation: h2≤0.5 h1. By setting h2≤0.5 h1, 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, not only can the first indoor heat exchanger 210 have a larger heat exchange area for heat exchange, but also can facilitate the compact configuration of the first indoor heat exchanger 210 and the second indoor heat exchanger 220 to make the structural design of the window air conditioner 10 miniaturized.

As shown in FIG. 11, in some embodiments, the heat exchange tubes in the first indoor heat exchanger 210 may be arranged in a columns in the thickness direction of the first indoor heat exchanger 210. The heat exchange tubes in the second indoor heat exchanger 220 may be arranged in b columns in the thickness direction of the second indoor heat exchanger 220. a and b can satisfy the relation: a>b. In this manner, by having the thickness of the arrangement of the heat exchanger tubes in the first indoor heat exchanger 210 being greater than the thickness of the arrangement of the heat exchanger tubes in the second indoor heat exchanger 220, it is possible for the first indoor heat exchanger 210 to have a larger heat exchanger area than the second indoor heat exchanger 220, which can make the first indoor heat exchanger 210 have a higher heat exchanger performance during use, and can make the structural arrangement of the second indoor heat exchanger 220 more compact, and can also make the arrangement of the first indoor heat exchanger 210 and the second indoor heat exchanger 220 inside the casing 100 more compact, resulting in the process of arranging the window air conditioner 10 on the window 11 more simple and reliable, and allowing the window air conditioner 10 to provide a higher heat exchange performance to improve the indoor environment.

As shown in FIGS. 5 and 6, in other embodiments, the casing 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 arranged on the base 110. The window air conditioner 10 may further include water collection trays 600. The water collection trays 600 may be provided on the base 110. The water collection trays 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 collection trays 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. As described above, by providing the water collection trays 600 below the first indoor heat exchanger 210 and the second indoor heat exchanger 220, the condensed water generated during heat exchange between the first indoor heat exchanger 210 and the second indoor heat exchanger 220 can flow in the extending direction of the first indoor heat exchanger 210 and the second indoor heat exchanger 220, and can be collected in the water collection trays 600 provided opposite to the first and second heat exchangers.

In some embodiments, the base 110 may be formed with water collection tanks 111 below the outdoor fan assembly 500 and the outdoor heat exchanger 400. The water collection tray 600 may have a drainage nozzle 610. The drainage nozzle 610 may extend above the water collection tank 111. As described above, by providing the water collection tank 111 on the base 110, when the first indoor heat exchanger 210 and the second indoor heat exchanger 220 perform heat exchange, the condensed water generated can flow along the extending direction of the first indoor heat exchanger 210 and the second indoor heat exchanger 220, flow to the opposite water collection trays 600 for collection, and then enter the water collection tanks 111 through the drainage nozzles 610, so that the collected condensed water can be subjected to subsequent unified treatment. 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 collection tank 111, and the water vapor after the evaporation of the condensed water can be dissipated to the outdoors.

As shown in FIGS. 5, 7, and 9, in other embodiments, the casing 100 may include an indoor housing 120 and an outdoor housing 130. The indoor housing 120 may be disposed on the base 110 and cover the indoor heat exchanger 200 and the indoor fan assembly 300. The indoor heat exchanger 200 and the indoor fan assembly 300 may correspondingly be constructed between the indoor housing 120 and the base 110. The outdoor housing 130 may be disposed on the base 110 and houses the outdoor heat exchanger 400 and the outdoor fan assembly 500. The outdoor heat exchanger 400 and the outdoor fan assembly 500 may correspondingly be 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 drainage nozzle 610 may pass through the through hole 1211 and extend into the space covered by the outdoor housing 130.

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

Meanwhile, by providing the indoor housing 120 with a through hole 1211, and the through hole 1211 is suitably arranged opposite to the drainage nozzle 610, the drainage nozzle 610 can extend into the outdoor housing 130 to discharge condensate water from the water collection tray 600 and collect it in the water collection tank 111. In this way, the discharge of condensed water in the window air conditioner 10 can be made more reliable.

As shown in FIGS. 5, 9 and 10, in other embodiments, the water collection tray 600 may be provided with a first support base 620. 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 collection 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. Thus, by providing the first support bases 620 on the water collection tray 600 and supporting the first indoor heat exchanger 210 by the first support bases 620, the installation of the first indoor heat exchanger 210 on the water collection trays 600 can be made more reliable.

In some embodiments, the water collection 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 collection tray 600, respectively. The two second support bases 630 may be supported on the left and right sides of the second indoor heat exchanger 220, respectively. Thus, by providing the second support bases 630 on the water collection tray 600 and supporting the second indoor heat exchanger 220 by the second support bases 630, the installation of the second indoor heat exchanger 220 on the water collection trays 600 can be made more reliable.

In addition, the first support bases 620 support the first indoor heat exchanger 210 and the second support bases 630 support the second indoor heat exchanger 220, so that when moisture is condensed on the first indoor heat exchanger 210 and the second indoor heat exchanger 220, the condensed water can be condensed on the first indoor heat exchanger 210 and the second indoor heat exchanger 220, and the condensed water can flow along the first support bases 620 and the second support bases 630, and is finally collected on the water collection trays 600 for moisture collection, so that the indoor airflow through the first indoor heat exchanger 210 and the second indoor heat exchanger 220 can be purified. As shown in FIGS. 5, 9 and 10, in some other embodiments, the water collection trays 600 and the base 110 may be disposed at intervals in the vertical direction or along a height direction of the casing. An air inlet channel 640 may be formed between the water collection tray 600 and the base 110. The outlet of the air inlet channel 640 may be located below the second indoor heat exchanger 220. Thus, the air inlet channel 640 formed between the water collection tray 600 and the base 110 allows the indoor airflow to flow through the air inlet channel 640. The outlet of the air inlet channel 640 is located below the second indoor heat exchanger 220, allowing the indoor airflow to contact and then exchange heat with the second indoor heat exchanger 220 after passing through the air inlet channel 640. This allows the indoor airflow to better improve the indoor environment when entering the indoor environment, thereby providing higher performance during use of the window air conditioner 10.

As shown in FIGS. 5 and 7, in some embodiments, a first indoor air inlet 112 may be formed at 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, allowing the indoor airflow to exchange heat with the indoor heat exchanger 200. The indoor fan assembly 300 may discharge the heat-exchanged airflow outdoors through the air outlet 113.

As shown in FIGS. 5, 6, 7 and 10, in some embodiments, a second indoor air inlet 114 may be formed at the front side of the base 110. The first indoor air inlet 112 and the second indoor air inlet 114 may communicate with the air inlet channel 640, respectively. Thus, by communicating the first indoor air inlet 112 and the second indoor air inlet 114 with 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. This enables the indoor airflow to better enter the indoor housing 120 to exchange heat with the indoor heat exchanger 200, and further improves the working efficiency of the window air conditioner 10 during use, allowing for quicker improvement of the indoor environment.

As shown in FIGS. 5 and 10, in some embodiments, the bottom of the water collection tray 600 may be provided with a plurality of support ribs 650. The plurality of support ribs 650 may be supported by the base 110 and extend in the front-rear direction (i.e., the length direction of the base 110). Thus, by providing a plurality of support ribs 650 on the water collection tray 600 and providing the plurality of support ribs 650 at intervals, the support ribs 650 can improve the structural strength of the base 110, and further, the support effect of the base 110 on the indoor heat exchanger 200, the indoor fan assembly 300, the outdoor heat exchanger 400, and the outdoor fan assembly 500 can be improved. In addition, the plurality of support ribs 650 can also provide a flow guide function, and the airflow can be circulated under the guidance action of the support ribs 650. This allows the airflow to be circulated and exchange heat in the extension direction of the support ribs 650, thereby improving the operating performance of the window air conditioner 10 during use.

As shown in FIGS. 5 and 9, in other embodiments, the water collection tray 600 may include a bottom plate 660, a front water baffle 670, and a rear water baffle 680. The front baffle 670 may be connected to a front edge of the bottom plate 660. The front water baffle 670 is disposed relative to the bottom plate 660. For example, the front water baffle 670 may extend obliquely downwards in a front-to-rear direction. The rear water baffle 680 may be connected to a rear edge of the bottom plate 660. The rear water baffle 680 is disposed relative to the bottom plate. For example, the rear water baffle 680 may extend obliquely upwardly in a front-to-rear direction.

In this way, the front water baffle 670 is connected to the front side of the bottom plate 660, and the front water baffle 670 extends obliquely downwards in the front-to-rear direction, and the rear water baffle 680 is connected to the rear side of the bottom plate 660, and the rear water baffle 680 extends obliquely upwards in the front-to-rear direction, so that the front water baffle 670 and the rear water baffle 680 can be arranged in the flow and collection direction of the condensed water, making the collection process of the condensed water reliable. This also allows condensate to be better collected on the water collection tray 600 for subsequent use, ensuring that the airflow circulating within the window air conditioner 10 is purer. This enhances the improvement of the indoor environment and enhances the comfort of users within the indoor environment.

Other configurations and operations of the window air conditioner 10 according to embodiments of the present disclosure are known to those of ordinary skill in the art and will not be described in detail herein.

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