DETAILED DESCRIPTION
Embodiments of the present disclosure will be described in detail and examples of the embodiments will be illustrated in the accompanying drawings, where same or similar reference numerals are used to indicate same or similar members or members with same or similar functions. The embodiments described herein with reference to the drawings are explanatory, which aim to illustrate the present disclosure, but shall not be construed to limit the present disclosure.
A window air conditioner 10 according to embodiments of the present disclosure will be described with reference to the drawings.
FIGS. 1-28 illustrate the window air conditioner 10 according to embodiments of the present disclosure.
The window air conditioner 10 is supported in a window opening 31 of a wall 3, and a movable window 4 is provided in the window opening 31. The window air conditioner 10 includes a casing 2, the casing 2 includes a receiving groove 21 at an outer peripheral wall, and the receiving groove 21 has an open top, an open left side, and an open right side (an up-down direction as indicated by arrow A in FIGS. 1-2, and a left-right direction as indicated by arrow C in FIGS. 1-2). The casing 2 is divided into an indoor part and an outdoor part through the receiving groove 21. At least a part of the window 4 is capable of extending into the receiving groove 21. The indoor part is provided with an indoor heat exchanger and an indoor fan therein, while the outdoor part is provided with an outdoor heat exchanger and an outdoor fan therein.
In the window air conditioner 10 according to embodiments of the present disclosure, the casing 2 is partitioned into the indoor part and the outdoor part by the receiving groove 21 in the outer peripheral wall of the casing 2, and at least a part of the window 4 can extends into the receiving groove 21. This facilitates installation of the window air conditioner 10 into the window opening 31, facilitates the fitting between the window air conditioner 10 between the window opening 31 and the window 4, thereby improving structural reliability and stability of the window air conditioner 10 after the installation, and facilitating operational reliability of the window air conditioner 10.
Moreover, the casing 2 is partitioned into the indoor part and the outdoor part by the receiving groove 21, such that a space between the window 4 and the window opening 31 is sealed, thereby improving a sealing effect at the window opening 31 after the window air conditioner 10 is installed. Therefore, it is convenient to improve a thermal insulation effect and a sound insulation effect between the indoors and the outdoors, avoid influence of an outdoor temperature on an indoor temperature, and prevent outdoor noise from generating any influence on the indoors, thereby upgrading user experience, and improving functionality and adaptability of the window air conditioner 10.
In addition, the casing 2 is partitioned into the indoor part and the outdoor part by the receiving groove 21, such that the window air conditioner 10 cooperates with the window 4 and the window opening 31, in which way the appearance of the window air conditioner 10 is more tidy and beautiful after installation, thereby upgrading the user experience.
Further, compared with the related art where a receiving groove is recessed upwards from a bottom wall of a casing, since the top, the left side, and the right side of the receiving groove 21 are open, the window air conditioner 10 can be stressed more uniformly and be prevented from being damaged by a large force exerted on a top wall of the window air conditioner 10, thereby enhancing the arrangement reliability and operational performance of the window air conditioner 10, and moreover, an air outlet of the window air conditioner 10 can be set at a higher position, which makes it convenient for an air-out flow to flow in the indoor space, increases temperature regulation efficiency of the window air conditioner 10, and improves an adjustment effect of the window air conditioner 10 on the indoor temperature.
Therefore, the window air conditioner 10 according to the embodiments of the present disclosure has advantages, such as easy installation, good sealing performance, and the like.
The window air conditioner 10 according to specific embodiments of the present disclosure will be described below with reference to the drawings.
In some specific embodiments of the present disclosure, FIGS. 1-28 illustrate the window air conditioner 10 according to embodiments of the present disclosure.
Specifically, as shown in FIGS. 20-23, the window air conditioner 10 further includes a sealing assembly 1 used to seal a space between the window 4 and the window opening 31, and the sealing assembly 1 is arranged at the casing 2. Thus, by means of the sealing assembly 1, the sealing performance between the window 4 and the window opening 31 can be enhanced, and the thermal insulation effect and the sound insulation effect between the indoors and the outdoors can be improved.
Optionally, as shown in FIGS. 20-23, the casing 2 includes a chassis 22, a rear case 23, and a front case 26 (a front-rear direction indicated by arrow B in FIGS. 1-2), and the rear case 23 is fixed at the chassis 22. The front case 26 is fixed at the chassis 22, and the front case 26 and the rear case 23 are spaced apart in the front-rear direction to form the receiving groove 21. The chassis 22, the rear case 23, and the front case 26 are independently machined parts, which not only facilitates the formation of the receiving groove 21 and hence the fitting between the window air conditioner 10 and the window 4, but also facilitates the processing of the chassis 22, the rear case 23, and the front case 26 individually to allow the chassis 22, the rear case 23, and the front case 26 to be processed by using different materials. For example, the rear case 23 is a sheet metal piece, and the front case 26 is a plastic piece, which improves the structural performance and the appearance of the casing 2.
Specifically, as shown in FIG. 20 to FIG. 23, the casing 2 further includes an intermediate partition board 27 fixed at the chassis 22 and located in the receiving groove 21, and front and rear ends of the intermediate partition board 27 cooperate with the rear case 23 and the front case 26, respectively. In such a way, a lower surface of the window 4 can abut against the intermediate partition board 27, which facilitates the wiring and drainage of the window air conditioner 10 and enhances the operational reliability of the window air conditioner 10.
More specifically, the intermediate partition board 27 is connected to a rotating bracket 300 by a screw.

The window air conditioner 10 is suitable to be supported on the window sill 101. Both sides of the window sill 101 may be an indoor side 101b and an outdoor side 101a, respectively. The window air conditioner 10 includes an outdoor assembly 1a, an indoor assembly 2a, and a partition assembly 3a. 
As shown in FIG. 1 and FIG. 29, the outdoor assembly 1a is located on the outdoor side 101a of the window sill 101, and the outdoor assembly 1a includes an outdoor housing 11, an outdoor heat exchanger 12, an outdoor fan 13, and an electric control box 14, in which the outdoor heat exchanger 12, the outdoor fan 13, and the electric control box 14 are arranged in the outdoor housing 11. The outdoor housing 11 has an outdoor air inlet 111a and an outdoor air outlet 112a. It could be understood that the outdoor assembly 1a includes the outdoor housing 11, the outdoor heat exchanger 12, the outdoor fan 13 and the electric control box 14, and the outdoor heat exchanger 12, the outdoor fan 13 and the electric control box 14 are arranged in the outdoor housing 11. When the outdoor fan 13 is in operation, the outdoor air can flow into the outdoor housing 11 through the outdoor air inlet 111a to exchange heat with the outdoor heat exchanger 12, and after heat exchange the air can flow out through the outdoor air outlet 112a. 
The indoor assembly 2a is provided on the indoor side 101b of the window sill 101, and the indoor assembly 2a includes an indoor housing 21a, an indoor heat exchanger 22a, and an indoor fan 23a, in which the indoor heat exchanger 22a and the indoor fan 23a are arranged in the indoor housing 21a. The indoor housing 21a has an indoor air inlet 211a and an indoor air outlet 212. It could be understood that the indoor assembly 2a includes the indoor housing 21a, the indoor heat exchanger 22a, and the indoor fan 23a, and the indoor heat exchanger 22a and the indoor fan 23a are both arranged in the indoor housing 21a.

In other words, the receiving groove 21 is open on the top and on both side in a length direction of the receiving groove 21 (e.g., left and right sides in FIG. 1). When the window air conditioner 10 is installed on the window sill 101, the receiving groove 21 can be arranged opposite to the window 4 above the window sill 101, and the window 4 can be pushed and pulled in the up-down direction to change a ventilation area of the mounting opening 102a. Moreover, the window 4 can be moved downwards into the receiving groove 21 such that at least a part of the window 4 extends into the receiving groove 21 and hence the window 4 can separate the outdoor assembly 1a from the indoor assembly 2a. Thus, it is possible to prevent operation noise of the outdoor assembly 1a from being transmitted to the indoor side 101b to a certain extent, thereby upgrading the user experience, and preventing outdoor rainwater and the like from flowing into the room to ensure indoor cleanliness to a certain extent, thereby facilitating the maintenance of the window air conditioner 10. Moreover, the window air conditioner 10 has a flexible structure and is easy to install. It is not necessary to provide a mounting opening 102a in the wall to match the shape of the window air conditioner 10, and the installation of the window air conditioner 10 can be realized by using the mounting opening 102a of the wall 3 that is configured to mount the window 4, thereby lowering the installation requirements of the window air conditioner 10.
The indoor assembly 2a and the outdoor assembly 1a can be separated from each other, such that the indoor housing 21a and the outdoor housing 11 can be separated, such that the structures of the indoor housing 21a and the outdoor housing 11 are simplified, the processing thereof becomes convenient, and meanwhile, the indoor housing 21a and the outdoor housing 11 can be sequentially installed, thereby facilitating the assembly and installation of the window air conditioner 10. With the partition assembly 3a between the indoor assembly 2a and the outdoor assembly 1a to form the receiving groove 21 between the outdoor assembly 1a and the indoor assembly 2a, the window 4 can be moved downwards into the receiving groove 21 to separate the outdoor assembly 1a from the indoor assembly 2a, thereby preventing the operation noise of the outdoor assembly 1a from being transmitted to the indoor side 101b, and hence improving user comfort. The electric control box 14 is arranged in the outdoor housing 11, and the outdoor housing 11 can protect the electrical control box 14 to a certain extent. Moreover, it is unnecessary to reserve a space for the arrangement of the electrical control box 14 in the indoor housing 21a, thereby reducing the volume of the indoor assembly 2a, saving the space occupied by the indoor assembly 2a, lowering the requirement of the window air conditioner 10 for the installation space on the indoor side 101b, and improving the applicability of the window air conditioner 10, that is, the window air conditioner 10 can be applied to situations where the installation space on the indoor side 101b is small.
For the window air conditioner 10 according to the embodiments of the present disclosure, the partition assembly 3a is provided and forms the receiving groove 21 together with the outdoor assembly 1a and the indoor assembly 2a, such that the window 4 can be moved downwards into the receiving groove 21, thereby preventing the operation noise of the outdoor assembly 1a from being transmitted to the indoor side 101b, and improving the user comfort. Moreover, the electric control box 14 is provided in the outdoor housing 11, which reduces the volume of the indoor assembly 2a, lowers the requirement of the window air conditioner 10 for the installation space on the indoor side 101b, further lowers the installation requirement of the window air conditioner 10, and improves the applicability of the window air conditioner 10.

Thus, the overall structure of the window air conditioner 10 is stabilized, and the overall structure of the window air conditioner 10 is conveniently installed on the window sill 101, thereby improving the installation efficiency of the window air conditioner 10. Since the electric control box 14 is mounted on the chassis 4a, the installation reliability of the electric control box 14 is ensured, and the electric control box 14 does not need to be fixed to other components, which simplifies the installation of the electric control box 14 and facilitates the installation of the electric control box 14.
In an example of FIG. 34, the electric control box 14 can be provided with a connecting member 143 on an outer surface thereof. The connecting member 143 can be arranged at a bottom of the electric control box 14.

Thus, the structures of the box body 141 and the top cover 142 are simplified, the processing and mounting of the box body 141 and the top cover 142 becomes convenient, and the assembly of the electric control box 14 is facilitated.
Specifically, a circuit board is provided in the mounting chamber 141a, and the circuit board can be mounted in the box body 141 by means of a mounting member. For example, the box body 141 includes a limiting slot therein, and the mounting member extends into the limiting slot to implement the installation of the circuit board, thereby improving the assembly efficiency of the electric control box 14. The mounting member can be a plastic member, thereby facilitating the formation of the mounting member and satisfying the structural requirement of the mounting member easily, and the plastic member can bring about a good insulation effect. Certainly, the mounting member can also be made of other materials.
During the installation of the electric control box 14, the box body 141 can be installed first; then the circuit board is mounted in the box body 141 by means of the mounting member, such that the circuit board is placed in the mounting chamber 141a; and finally the top cover 142 is arranged on the top of the box body 141 to fixedly connect the top cover 142 with the box body 141. Thus, the installation process of the electric control box 14 is simple, realizing the quick installation of the electric control box 14. For example, in the examples of FIGS. 34 and 35, opposite ends of the top cover 142 are each provided with a flange 142a, and an inner surface of the flange 142a can abut against an outer peripheral wall of the box body 141 to limit the positions of the top cover 142 and the box body 141, thereby further facilitating the assembly of the electric control box 14.
Optionally, the box body 141 and the top cover 142 may be sheet metal pieces. Even if the electric control box 14 is sparked or ignited due to high temperature during the operation, the electric control box 14 can also perform good fireproof and fire-barrier functions, and the electric control box 14 also has a good waterproof function to prevent rainwater flowing into the outdoor housing 11 from hitting the electric control box 14 to cause a short circuit or the like, thereby ensuring the safety of the electric control box 14. Certainly, the box body 141 and the top cover 142 may also be made of other materials, which is not limited thereto.
In some specific embodiments of the present disclosure, as shown in FIG. 1 and FIG. 2, at least a part of the outdoor air inlet 111a is formed in a top wall of the outdoor housing 11. It could be understood that the outdoor air inlet 111a can include a first outdoor air inlet 1111 formed in the top wall of the outdoor housing 11. The outdoor air can flow into the outdoor housing 11 through the first outdoor air inlet 1111 from top to bottom to exchange heat with the outdoor heat exchanger 12. In such a way, a requirement on the installation height of the window air conditioner 10 is lowered to a certain extent, and air introduction into the window air conditioner 10 can get rid of influence by factors such as obstacles on the left and right sides of the outdoor assembly 1a, thereby ensuring that the outdoor air inlet 111a has a sufficient air inlet area to guarantee an air volume in the outdoor assembly 1a. Moreover, under the same air volume, the operation noise of the outdoor assembly 1a can be reduced, and the noise transmitted to the indoor side 101b during the operation of the outdoor assembly 1a can be further reduced.
Further, in an example of FIG. 33, the outdoor air outlet 112a can be formed on a side of the outdoor housing 11 away from the indoor housing 21a (e.g., a rear side in FIG. 33). The outdoor air inlet 111a can further include a second outdoor air inlet 1112 located in a side wall of the outdoor housing 11 to ensure the air inlet area of the outdoor air inlet 111a. In other words, the second outdoor air inlet 1112 can be located in a left side wall and/or a right side wall of the outdoor housing 11. That is, one or two second outdoor air inlets 1112 may be provided. When one second outdoor air inlet 1112 is provided, the second outdoor air inlet 1112 may be located in the left side wall or the right side wall of the outdoor housing 11; when two second outdoor air inlets 1112 are provided, the two second outdoor air inlets 1112 may be located in the left side wall and the right side of the outdoor housing 11, respectively.
It could be understood that the outdoor air inlet 111a and the outdoor air outlet 112a can be arranged in other positions according to actual needs, which is not limited thereto.
When the electric control box 14 is located below the first outdoor air inlet 1111, at least the top wall of the electric control box 14 may be waterproof, to prevent rainwater flowing into the outdoor housing 11 via the first outdoor air inlet 1111 from hitting the electric control box 14 to cause a short circuit or the like, thereby ensuring the operation safety of the electric control box 14.
In some specific embodiments of the present disclosure, the outdoor heat exchanger 12 is located on a side of the outdoor fan 13 away from the indoor assembly 2a (e.g., a rear side in FIG. 34), and the outdoor fan 13 may be an axial flow fan. For example, as shown in FIGS. 34, 36, 38, and 39, the outdoor heat exchanger 12 may be located on a side of the outdoor fan 13 away from the indoor assembly 2a in an axial direction of the outdoor fan 13, such that the outdoor heat exchanger 12 has a relatively large area facing the outdoor fan 13 in the axial direction of the outdoor fan 13. When the outdoor fan 13 is in operation, the outdoor fan 13 pushes air to allow the air to flow in the same direction as the axial direction of the outdoor fan 13, and drives the air to flow through the outdoor heat exchanger 12. The air contacts the outdoor heat exchanger 12 at a relatively large area, such that the air can be in full contact with the outdoor heat exchanger 12, thereby ensuring the heat exchange efficiency of the outdoor heat exchanger 12.
Specifically, in examples of FIG. 30 and FIGS. 39-42, the outdoor fan 13 includes an axial flow fan blade 131 and a water splash ring 132, a side of the axial flow fan blade 131 away from the outdoor heat exchanger 12 is provided with an outdoor motor 136, and the outdoor motor 136 is connected to the axial flow fan blade 131 to drive the axial flow fan blade 131 to rotate. The water splash ring 132 is connected to an outer edge of the axial flow fan blade 131, such that the water splash ring 132 can be rotated synchronously with the axial flow fan blade. A central axis of the outdoor fan 13 can extend in the horizontal direction. A water collecting groove 41 is provided below the water splash ring 132, such that condensation water produced during the operation of the window air conditioner 10 can be collected in the water collecting groove 41. When the outdoor heat exchanger 12 is used as a condenser, the condensation water produced due to the indoor heat exchanger 22a can be collected in the water collecting groove 41. When a liquid level in the water collecting groove 41 is high and the water splash ring 132 is immersed below the liquid level, the water splash ring 132 can bring up the water in the water collecting groove 41 to form water droplets during its rotation, and the water droplets can evenly strike on the outdoor heat exchanger 12 under the action of air blowing of the axial flow fan blade 131. Since the outdoor heat exchanger 12 is at a high temperature, the water droplets exchange heat with the outdoor heat exchanger 12 to lower the temperature of the outdoor heat exchanger 12, thereby reducing the power of the window air conditioner 10, and improving the cooling energy efficiency ratio of the window air conditioner 10.
As shown in FIG. 39, the outdoor assembly 1a further includes an air guide ring 15 around the axial flow fan blade 131, and the air guide ring 15 can be substantially formed in a cylindrical structure. The air guide ring 15 is located on a side of the water splash ring 132 away from the outdoor heat exchanger 12 to realize an air guide function and ensure the air volume to the axial flow fan blade 131. The air guide ring 15 and the water splash ring 132 are spaced apart from each other along an axial direction of the axial flow fan blade 131, and in the axial direction of the axial flow fan blade 131, a distance between the water splash ring 132 and the air guide ring 15 is represented by L1 and L1≥5 mm, so as to ensure a sufficient separation distance between the water splash ring 132 and the air guide ring 15 to avoid interference between the air guide ring 15 and the water splash ring 132, which may otherwise affect normal rotation of the water splash ring 132.
L1 may refer to the separation distance between the water splash ring 132 and the air guide ring 15 in the axial direction of the axial flow fan blade 131. For example, L1 may be 7 mm, 8.4 mm, 9 mm, or etc. Further, L1 satisfies L1≥10 mm, and for example, L1 may be 11 mm, 12.6 mm, 13.2 mm, or etc.
Further, as shown in FIG. 39, the air guide ring 15 and the outdoor heat exchanger 12 are spaced apart from each other in the axial direction of the axial flow fan blade 131, and in the axial direction of the axial flow fan blade 131, a distance between the water splash ring 132 and the outdoor heat exchanger 12 is represented by L2 and L2≥12 mm, so as to ensure a sufficient separation distance between the water splash ring 132 and the outdoor heat exchanger 12 to avoid interference between the outdoor heat exchanger 12 and the water splash ring 132, which may otherwise affect the normal rotation of the water splash ring 132.
Here, L2 may refer to the separation distance between the outdoor heat exchanger 12 and the air guide ring 15 in the axial direction of the axial flow fan blade 131. For example, L2 may be 12.9 mm, 13.7 mm, 14 mm, or etc.
In an example of FIG. 39, the outdoor motor 136 can be mounted by means of a motor frame 137. An outer side of the axial flow fan blade 131 is provided with a back panel 17, and the back panel 17 is located on a side of the motor frame 136 adjacent to the outdoor heat exchanger 12. The back panel 17 is fixedly connected to the outdoor heat exchanger 12 and can form an air flow passage, and the axial flow fan blade 131 drives air in the air flow passage to flow to exchange heat with the outdoor heat exchanger 12. The back panel 17, the motor frame 136, and the air guide ring 15 can be a one-piece member. For example, the back panel 17, the motor frame 136 and the air guide ring 15 can be integrally formed.
Specifically, as shown in FIGS. 40, 41, and 45, the water splash ring 132 and the outer edge of the axial flow fan blade 131 are connected by a connecting portion 133. The connecting portion 133 includes a first segment 1331 and a second segment 1332. The first segment 1331 extends from the outer edge of the axial flow fan blade 131 towards the outdoor heat exchanger 12, and an extension direction of the first segment 1331 can be in parallel with a central axis 1310 of the axial flow fan blade. The second segment 1332 extends from an extension tail end 1331a of the first segment towards a direction away from the central axis 1310 of the axial flow fan blade, and an extension direction of the second segment 1332 can be perpendicular to the central axis 1310 of the axial flow fan blade. Thus, the connecting portion 133 is substantially L-shaped. The water splash ring 132 is connected with an extension tail end 1332a of the second segment to ensure the connection reliability between the water splash ring 132 and the axial flow fan blade 131. At the same time, since the connecting portion 133 extends in a bent form to avoid the air guide ring 15, so as to prevent the air guide ring 15 from interfering with the connecting portion 133 and hence from affecting normal rotation of the connecting portion 133. Moreover, the connecting portion 133 can also drive the condensation water during the rotation to improve a water splash effect of the water splash ring 132. Thus, the normal rotation of the axial flow fan blade 131 is ensured, by avoiding a situation where the connecting portion 133 is formed in a straight strip shape and is prone to interfering with the air guide ring 15 and the outdoor heat exchanger 12.
Further, in examples of FIGS. 44 and 45, the water splash ring 132 is formed in an annular structure, and the water splash ring 132 has a diameter gradually increased in a direction from the air guide ring 15 to the outdoor heat exchanger 12, such that a tangential force is formed at an end of the water splash ring 132, and the water droplets are dispersed effectively under the action of the tangential force to ensure the water splash effect of the water splash ring 132.
It should be noted that the diameter of the water splash ring 132 may refer to an inner diameter of the water splash ring 132, that is, the inner diameter of the water splash ring 132 is gradually increased along the direction from the air guide ring 15 to the outdoor heat exchanger 12. In such a case, an outer diameter of the water splash ring 132 can remain constant or can also be gradually increased in the direction from the air guide ring 15 to the outdoor heat exchanger 12, but is not limited thereto. When the inner diameter and the outer diameter of the water splash ring 132 are both gradually increased in the direction from the air guide ring 15 to the outdoor heat exchanger 12, the water splash ring 132 can realize an equal-thickness design.
Specifically, as shown in FIG. 45, when the inner diameter of the water splash ring 132 is gradually increased linearly in the direction from the air guide ring 15 to the outdoor heat exchanger 12, an inner wall surface of the water splash ring 132 can be formed into a substantially tapered surface. At this time, a taper angle α corresponding to the inner wall surface of the water splash ring 132 can satisfy: 30°≤α≤90°. In other words, an included angle β between an extension direction of the inner wall surface of the water splash ring 132 and a central axis 1320 of the water splash ring can satisfy: 15°≤α≤45°.
Further, as shown in FIG. 42 and FIG. 43, an inner peripheral surface of the water splash ring 132 is provided with at least one water splash rib 134, and the water splash rib 134 can be formed in such a way that the inner peripheral surface of the water splash ring 132 partially protrudes inwards, thereby further improving the water splash effect of the water splash ring 132. One or more water splash ribs 134 can be provided. When a plurality of water splash ribs 134 are provided, the plurality of water splash ribs 134 can be spaced apart along a circumferential direction of the water splash ring 132. An end of the water splash ring 132 adjacent to the air guide ring 15 has an anti-backflow ring 135 extending towards the central axis 1320 of the water splash ring. The anti-backflow ring 135 can be formed in an annular structure, and the anti-backflow ring 135 can be formed in such a way that the inner peripheral surface of the water splash ring 132 partially protrudes inwards. Hence, during the rotation of the water splash ring 132, the anti-backflow ring 135 prevents water from flowing back, and prevents the water droplets from striking on the side of the water splash ring 132 away from the outdoor heat exchanger 12, thereby further ensuring the water splash effect. The extension tail end 1332a of the second segment can be connected to the anti-backflow ring 135.
In some specific embodiments of the present disclosure, the indoor air outlet 212 is located above the indoor air inlet 211a, and the indoor air outlet 212 extends obliquely upwards along a direction from the outdoor assembly 1a to the indoor assembly 2a. For example, as shown in FIGS. 1, 2 and 33, the indoor air inlet 211a can be formed in a side wall of the indoor housing 21a away from a side (e.g., a front side in FIG. 1) of the outdoor housing 11. The indoor air outlet 212 can be spaced apart from the indoor air inlet 211a. The indoor air outlet 212 can extend obliquely upwards with respect to the horizontal direction, such that a distance between the indoor air outlet 212 and the indoor air inlet 211a in the up-down direction can be increased in the case of the same air volume, thereby enlarging an opening area of the indoor air inlet 211a and an air inlet area of the indoor air inlet 211a, and increasing the air volume into the indoor assembly 2a. In the case of the same air volume, the operation noise of the indoor assembly 2a can be reduced, the sound quality of the window air conditioner 10 can be improved, and comfort is further upgraded for the user. Since the indoor air outlet 212 obliquely extends upwards, air is obliquely blown upwards through the indoor air outlet 212, such that the indoor air outlet 212 has a suitable air supply distance and air supply height to ensure the comfort of air supply from the window air conditioner 10.
Regarding that the indoor air outlet 212 extends obliquely upwards, it could be understood that an opening direction of the indoor air outlet 212 extends obliquely upwards, or air is obliquely blown upwards through the indoor air outlet 212. For example, an angle between the opening direction of the indoor air outlet 212 and the horizontal direction is represented by α, 0°<α<90°, and for example, α may be 35°, but is not limited thereto.
It should be noted that, in the description of the present disclosure, a first feature “above” a second feature includes a situation where the first feature is directly or obliquely above the second feature, or merely means that the first feature is at a height higher than the second feature. That is, the arrangement that the indoor air outlet 212 is located above the indoor air inlet 211a may include an embodiment in which the indoor air outlet 212 is directly above the indoor air inlet 211a, or an embodiment in which the indoor air outlet 212 is obliquely above the indoor air inlet 211a. 
Optionally, the indoor fan 23a can be a cross flow fan, and the indoor fan 23a includes a cross flow fan blade 231 whose axis extends in the horizontal direction. The cross flow fan blade 231 is easy to cooperate with the indoor air inlet 211a and the indoor air outlet 212, to evenly distribute the air-out volume and the air speed, and reduce the operation noise. The indoor fan 23a can include an air channel 230a, and the cross flow fan is arranged in the air channel 230a to drive the air in the air channel 230a to flow. Since the indoor air outlet 212 extends obliquely upwards with respect to the horizontal direction, the arrangement of the indoor air outlet 212 is facilitated, and the air channel 230a can be fully utilized, such that the air channel 230a and the indoor air outlet 212 cooperate with each other, thereby facilitating the arrangement of the air channel 230a and reducing the design cost of the window air conditioner 10.
Further, the window air conditioner 10 further includes the sealing assembly 1, and the sealing assembly 1 is pivotally connected to the partition assembly 3a to be rotatable in a stowed position (as shown in FIG. 1) and a sealing position (as shown in FIG. 24 and FIG. 2). When the sealing assembly 1 is pivoted to the stowed position, the sealing assembly 1 is stowed in the receiving groove 21; when the sealing assembly 1 is pivoted to the sealing position, the sealing assembly 1 realizes the sealing between the window sill 101 and the window 4. When the sealing assembly 1 is stowed in the receiving groove 21, it can be ensured that the overall structure of the window air conditioner 10 is small, and the sealing assembly 1 does not occupy the space on the left and right sides of the partition assembly 3a, which is applicable to an example that the wall 3 includes a mounting opening 102a matching the shape of the window air conditioner 10 (i.e., an example in which the mounting opening 102a has a width consistent with a width of the window air conditioner 10), and which facilitates packaging and transportation of the window air conditioner 10. When the sealing assembly 1 is pivoted out of the receiving groove 21 and reaches the sealing position, the sealing assembly 1 is completely or mostly pivoted to the left and right sides of the partition assembly 3a, which is applicable to an example that the window air conditioner 10 is mounted to the wall 3 including a mounting opening 102a of a greater width than the width of the window air conditioner 10. Thus, since the window air conditioner 10 includes the pivotable sealing assembly 1, the application range of the window air conditioner 10 can be broaden, and the sealing effect of the window air conditioner 10 installed in the examples of the mounting opening 102a can be ensured. When the outdoor temperature is low, such as in winter, the user can rotate the sealing assembly 1 to the sealing position to prevent the outdoor cold air from flowing into the room and affecting the comfort in the room.
For example, in examples of FIG. 24, FIG. 1 and FIG. 2, there may be two sealing assemblies 1, each of the sealing assemblies 1 is substantially formed in an elongated shape, and the two sealing assemblies 1 may be connected to two longitudinal ends of the partition assembly 3a, respectively. Each of the sealing assemblies 1 has a first end 51 and a second end 52 in its length direction, and the first end 51 of each of the sealing assemblies 1 is pivotally connected to the partition assembly 3a, such that the second end 52 of the sealing assembly 1 is rotatable about the first end 51. When the sealing assembly 1 is rotated to the sealing position, the sealing assembly 1 realizes the sealing between the window sill 101 and the window 4, and seals a gap between the window sill 101 and the window 4. When the sealing assembly 1 is rotated to the stowed position, the sealing assembly 1 can extend in the up-down direction to reduce the space occupied by the window air conditioner 10 and facilitate the transportation of the window air conditioner 10.

Referring FIGS. 1 and 2, the first sub-chamber 101c is used to bear the indoor assembly 2a of the window air conditioner 10, such that the indoor assembly 2a is arranged in the first sub-chamber 101c. The second sub-chamber 102 is used to bear the partition assembly 3a, such that the partition assembly 3a is arranged in the second sub-chamber 102. The third sub-chamber 103a is used to bear the outdoor assembly 1a of the window air conditioner 10, such that the outdoor assembly 1a is arranged in the third sub-chamber 103a. Referring to FIGS. 1 and 34, the partition assembly 3a is provided between the indoor assembly 2a and the outdoor assembly 1a, that is, the indoor assembly 2a and the outdoor assembly 1a are arranged on both sides of the partition assembly 3a. 
As shown in FIGS. 49 and 30, each side plate 12d has a concave portion 121a recessed towards the other side plate 12d, and the concave portion 121a constitutes a side wall of the second sub-chamber 102. Thus, each side plate 12d can include a first side portion 12a, a second side portion 12b, and a third side portion 12c. The first side portion 12a cooperates with the bottom plate 11a to form the first sub-chamber 101c, such that the first side portion 12a constitutes a side wall of the first sub-chamber 101c. The second side portion 12b cooperates with the bottom plate 11a to form the second sub-chamber 102, such that the second side portion 12b constitutes a side wall of the second sub-chamber 102. The third side portion 12c cooperates with the bottom plate 11a to form the third sub-chamber 103a, such that the third side portion 12c constitutes a side wall of the third sub-chamber 103a. Further, it should be noted that the concave portion 121a has a recessing depth which is not limited and may range, for example, from 1 cm to 5 cm.
As shown in FIGS. 49 and 30, the first side portion 12a and the third side portion 12c are connected to both sides of the second side portion 12b, and the second side portion 12b is located at a side of the first side portion 12a and the third side portion 12c adjacent to the other side plate 12d, such that the concave portion 121a is formed at a junction among the second side portion 12b, the first side portion 12a and the third side portion 12c. Thus, by providing the concave portion 121a in the side plate 12d, the strength of the side plate 12d can be reinforced, and the indoor assembly 2a, the outdoor assembly 1a, and the partition assembly 3a can be positioned or mounted at different places by means of the concave portion 121a, thereby improving the assembly efficiency of the window air conditioner 10.
Referring to FIG. 1, a receiving space R is formed above the partition assembly 3a and between the outdoor assembly 1a and the indoor assembly 2a, that is, the receiving space R is formed by a bottom wall (formed by an upper surface of the partition assembly 3a), an inner side wall (formed by an outer surface of the indoor assembly 2a), and an outer side wall (formed by an inner surface of the outdoor assembly 1a), which means the receiving space R is open on top, left and right sides thereof. Referring to FIGS. 24 and 29, the window air conditioner 10 is adapted to be supported on the window sill 101, and the window 4 above the window sill 101 can be moved downwards into the receiving space R, that is, when the window 4 above the window sill 101 moves downwards, at least a part of the window 4 can enter the receiving space R.
Therefore, the window air conditioner 10 according to the embodiments of the present disclosure has a flexible structure and is easy to install. It is not necessary to particularly provide a mounting opening in the wall 3 that matches the shape of the window air conditioner 10. The window opening for installation of the window 4 in the wall 3 can be used to realize the installation of the window air conditioner 10. Moreover, since the window 4 can be lowered into the receiving space R, the number of sealing plates can be reduced, saving the implementation cost. Further, since the indoor assembly 2a and the outdoor assembly 1a can be partitioned by the window 4, the noise of the outdoor assembly 1a transmitted to the room can be lowered, reducing the influence of noise on the user indoors.
The window air conditioner 10 according to embodiments of the present disclosure can further include the sealing assembly 1. Referring to FIGS. 1 and 2, the sealing assembly 1 is pivotally connected to the partition assembly 3a and is rotatable between the stowed position (as shown in FIG. 1) and the sealing position (as shown in FIG. 2). The sealing assembly 1 is stowed in the receiving space R when the sealing assembly 1 is pivoted to the stowed position (as shown in FIG. 1); an end portion 510a of the sealing assembly 1 is rotated into the concave portion 121a when the sealing assembly 1 is pivoted to the sealing position (as shown in FIG. 50).
Moreover, as shown in FIGS. 24 and 29, when the window 4 is lowered onto the partition assembly 3a, the sealing assembly 1 pivoted to the sealing position realizes the sealing between the window sill 101 and the window 4 (as shown in FIG. 24). Specifically, when the window 4 is lowered onto the partition assembly 3a, that is, when the lower surface of the window 4 abuts against the upper surface of the partition assembly 3a, there must be a certain air leakage space X between the lower surface of the window 4 and the upper surface of the window sill 101. Thus, by providing the sealing assembly 1, it is possible to solve problems, such as air leakage, noise and the like, due to the air leakage space X.
Therefore, when the sealing assembly 1 is stowed in the receiving space R, it can be ensured that the overall structure of the window air conditioner 10 is small, and the sealing assembly 1 does not occupy the space on the left and right sides of the chassis 4a, which is applicable to an example that the wall 3 includes a mounting opening matching the shape of the window air conditioner 10 (i.e., an example in which the mounting opening has a width consistent with a width of the window air conditioner 10), and which facilitates the packaging and transportation of the window air conditioner 10. When the sealing assembly 1 is pivoted out of the receiving space R and reaches the sealing position, the sealing assembly 1 is completely or mostly pivoted to the left and right sides of the chassis 4a, which is applicable to an example that the window air conditioner 10 is mounted to the window opening in the wall 3 (i.e., an example where the window opening has a width greater than the width of the window air conditioner 10). Thus, since the window air conditioner assembly 200a includes the pivotable sealing assembly 1, the application range of the window air conditioner 10 can be broaden, and the sealing effect of the window air conditioner 10 installed in the example of the window opening can be ensured.
As shown in FIGS. 50-52, when the window air conditioner assembly 200a includes the above sealing assembly 1, by providing the concave portion 121a, the smooth rotation of the sealing assembly 1 can be ensured and the sealing performance of installation of the window air conditioner 10 can be improved. Specifically, as shown in FIGS. 50-52, the sealing assembly 1 can include a body 51a and a pivoting portion 52a. The body 51a is pivotally connected to the partition assembly 3a through the pivoting portion 52a. In order to ensure the smooth pivot of the body 51a, a gap S is reserved between an end surface of the end portion 510a of the body 51a adjacent to the chassis 4a and an end surface (a surface of the second side portion 12b) of the chassis 4a facing the above end surface of the end portion 510a (as shown in FIG. 52). When the sealing assembly 1 is rotated to the sealing position, the end portion 510a is rotated into the concave portion 121a, such that the gap S is located in the concave portion 121a. Thus, in a direction from the inside to the outside (or a direction from the outside to the inside), the gap S is blocked by the first side portion 12a or the third side portion 12c, such that problems such as air leakage and noise due to the gap S can be avoided, thereby improving the sealing effect with a clever design.
In some embodiments of the present disclosure, as shown in FIG. 53, an upper surface of the bottom plate 11a can be provided with a rib 112b, and the rib 112b is located between the first sub-chamber 101c and the third sub-chamber 103a (that is, the rib 112b may be arranged on a side of the first sub-chamber 101c adjacent to the second sub-chamber 102, or the rib 112b may be arranged in the second sub-chamber 102, or the rib 112b may be arranged on a side of the third sub-chamber 103a adjacent to the first sub-chamber 101c). The rib 112b extends (may extend along a straight line and/or a curved line) in a direction from one side plate 12d to the other side plate 12d (in a left-right direction as shown in FIG. 53). By providing the rib 112b extending in the left-right direction between the first sub-chamber 101c and the third sub-chamber 103a, it is possible to prevent liquid such as rainwater on the outdoor side from entering the indoor side by means of the rib 112b, thereby improving the operational reliability of the window air conditioner 10.
As shown in FIG. 53, the rib 112b and the two side plates 12d can be spaced apart, that is, the rib 112b is not in contact with either of the side plates 12d. Thus, a reserved space K between the rib 112b and the side plates 12d can be utilized to facilitate the layout of a refrigerant pipe, an electric control line, a drainage channel, and the like (for example, a drainage channel can be arranged at a drainage via hole 401, and an electric control line and a refrigerant pipe can be arranged at a wiring via hole 402 in FIG. 54), thereby improving space utilization and enhancing the overall structural compactness of the window air conditioner 10.
In some embodiments of the present disclosure, as shown in FIGS. 30 and 55, the upper surface of the bottom plate 11a can be provided with a bracket 114a. At least one bracket 114a is provided and located in the second sub-chamber 102 to support the partition assembly 3a. That is, the partition assembly 3a can be supported and mounted on the bracket 114a. Thus, convenience and reliability of mounting of the partition assembly 3a and the chassis 4a can be improved by utilizing the bracket 114a. Further, the reliability of supporting the window 4 by the partition assembly 3a can be enhanced by the bracket 114a, that is, the pressure resistance of the partition assembly 3a is reinforced, and a problem that the partition assembly 3a is deformed by the window 4 is solved to some extent. Preferably, a plurality of brackets 114a are provided and spaced apart along a length direction of the second sub-chamber 102 (a left-right direction as shown in FIG. 30), such that the pressure resistance of the partition assembly 3a can be further enhanced, and the problem that the partition assembly 3a is deformed by the window 4 is further solved.
In some embodiments of the present disclosure, as shown in FIG. 49 and FIG. 56, the upper surface of the bottom plate 11a can include a drainage groove 111b recessed downwards. The drainage groove 111b is located in the third sub-chamber 103a, and includes a water collecting portion 1111a and a water guiding portion 1112a. The water collecting portion 1111a extends from one side plate 12d to the other side plate 12d, and the water guiding portion 1112a starts from an intersection of the water collecting portion 1111a and the side plate 12d and extends along the length direction of the side plate 12d towards the first sub-chamber 101c (a direction from the outside to the inside as shown in FIG. 49), which means that the water guiding portion 1112a is adjacent to the side plate 12d and extends along the side plate 12d. 
Therefore, since the water guiding portion 1112a is more adjacent to the first sub-chamber 101c which is used for bearing the indoor assembly 2a, the condensation water generated by the indoor assembly 2a can smoothly flow to the outdoor side, thereby reliability and convenience of drainage from the first sub-chamber 101c to the drainage groove 111b. Moreover, since the water guiding portion 1112a is adjacent to the side plate 12d, an overall space occupied by the drainage groove 111b in the third sub-chamber 103a can be reduced, which ensures that the third sub-chamber 103a can also have sufficient space (e.g., space A1, A2 shown in FIG. 56) to arrange the compressor 16, the electric control box 14, the outdoor fan 13, and the like (in combination with FIG. 34).
Referring to FIGS. 54 and 56-57, the window air conditioner 10 can further include a drain pan 24a. The drainage via hole 401 is formed between the partition assembly 3a and the chassis 4a. The indoor assembly 2a further includes the drain pan 24a below the indoor heat exchanger 22. The drain pan 24a has an extension segment 241a, and the extension segment 241a includes a drainage channel (the drainage channel may be a non-open channel or a top-open channel). The extension segment 241a passes through the drainage via hole 401 and extends to the water guiding portion 1112a, to output water in the drain pan 24a to the water guiding portion 1112a. Thus, the drain pan 24a can convey the condensation water to the water guiding portion 1112a through the extension segment 241a reliably and efficiently, thereby improving the drainage reliability and convenience, and enhancing the reliability of the window air conditioner 10.
Here, it is to be noted that the partition assembly 3a can include a partition member 41a, and a filling member provided between the partition member 41a and the chassis 4a. The material of the partition member 41a is not limited, and may be, for example, a sheet metal or the like. Thus, the reliability of partitioning the indoor assembly 2a from the outdoor assembly 1a, and the reliability of supporting the window 4 can be improved. The material of the filling member is not limited, and may be, for example, foam or the like, so as to bring about a heat preservation effect, a sound insulation effect, a sealing effect, and the like.
Returning to FIG. 56, two water guiding portions 1112a can be provided and arranged on two longitudinal sides of the water collecting portion 1111a (e.g., left and right sides shown in FIG. 56), which can further improve the reliability and convenience of drainage from the first sub-chamber 101c to the drainage groove 111b, and can adapt to the drain pan 24a of different structures. For example, whether the drain pan having the extension segment 241a on the left side is used, or the drain pan 24a having the extension segment 241a on the right side is used, it can be ensured that the extension segment 241a is in reliable connection with the water guiding portion 1112a, thereby improving the adaptability of the chassis 4a. 
In some embodiments of the present disclosure, as shown in FIGS. 29 and 58, the window air conditioner assembly 200a according to embodiments of the present disclosure can include the window air conditioner 10 according to any one of the embodiments of the present disclosure and a mounting frame assembly 200. The mounting frame assembly 200 enables the window air conditioner 10 to be supported on the window sill 101 through the mounting frame assembly 200, that is, the mounting frame assembly 200 is mounted on the window sill 101, and the window air conditioner 10 is mounted on the mounting frame assembly 200, thereby realizing the installation of the window air conditioner 10 on the window sill 101.
Referring to FIGS. 49 and 30, a lower surface of the bottom plate 11a can have an avoidance groove 113a recessed upwards. The avoidance groove 113a is at least located below the second sub-chamber 102 and is configured to receive the mounting frame assembly 200, and the mounting frame assembly 200 is arranged on the window sill 101 and received in the avoidance groove 113a. Here, it should be noted that the mounting frame assembly 200 does not need to be completely received in the avoidance groove 113a. Depending on a structure of the mounting frame assembly 200, only a portion of the mounting frame assembly 200 that is arranged on the window sill 101 and supports the bottom of the window air conditioner 10 needs to be received in the avoidance groove 113a. Thus, when the window air conditioner 10 is arranged on the mounting frame assembly 200, the portion of the mounting frame assembly 200 supported on the window sill 101 can be received in the avoidance groove 113a in the bottom of the window air conditioner 10, such that a lower surface of the window air conditioner 10 (i.e., a lower surface of the chassis 4a) can be in contact with the window sill 101, that is, the chassis 4a can be pressed onto the window sill 101, thereby enhancing the stability and reliability of installation of the window air conditioner 10.
As shown in FIG. 49, the avoidance groove 113a can extend along the length direction of the side plate 12d and extend to the drainage groove 111b. The drainage groove 111b is a downwards recess on the upper surface of the bottom plate 11a and located in the third sub-chamber 103a. Two sides of the avoidance groove 113a in a width direction are each provided with the rib 112b. The ribs 112b are arranged on the upper surface of the bottom plate 11a and located on the side of the first sub-chamber 101c adjacent to the second sub-chamber 102, and the ribs 112b extend in a direction from one side plate 12d to the other side plate 12d. That is, when the chassis 4a has the above avoidance groove 113a, the drainage groove 111b, and the rib 112b at the same time, all of which can be arranged in the above manner, thereby improving the structural compactness of the chassis 4a. 
Additionally, it should be noted that the material of the chassis 4a according to the embodiments of the present disclosure is not limited. For example, the chassis 4a may be made of a sheet metal, such as a galvanized sheet, a steel sheet, or the like. The thickness of the chassis 4a is not limited, and for example, can have a thickness of 0.8 to 1.2 mm. Thus, the structural reliability and cost efficiency of the chassis 4a can be easily improved.
