[0036] The following will be combined with the accompanying drawings to clearly and completely describe some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0037] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0038] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of some embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0039] When describing some embodiments, the word "connected" and its derivatives may be used. The term "connected" should be understood broadly. For example, "connected" can mean fixed, removable, or integrated; it can be directly connected or indirectly connected through an intermediary. The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0040] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.

[0041] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0042] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0043] As used herein, "parallel," "perpendicular," and "equal" include the stated conditions and conditions approximating the stated conditions within an acceptable range of deviation as determined by one of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0044] As used herein, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., to indicate orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.

[0045] Typically, a window air conditioner is installed in a wall mounting opening, with the indoor unit extending into the opening to exchange heat with the indoor environment. However, because the indoor unit is large and higher than the lower surface of the mounting opening, the window air conditioner easily blocks a large portion of the mounting opening, obstructing indoor vision, hindering indoor lighting, and resulting in poor sealing of the mounting opening.

[0046] In order to reduce the obstruction of the installation port by the window air conditioner. In some embodiments, the shape of the window air conditioner can be a special-shaped structure with a concave middle part (for example, a saddle shape). For example, the indoor unit and the outdoor unit are arranged at intervals, and the outdoor unit and the indoor unit are fixedly connected by a connecting structure. The upper surface of the connecting structure can be flush with the upper surfaces of the indoor unit and the outdoor unit, and in the height direction, the size of the connecting structure is smaller than the size of the indoor unit and the outdoor unit (that is, the middle part of the lower surface of the window air conditioner is concave). The connecting structure is arranged at the installation port to fix the window air conditioner at the installation port. In this way, the indoor unit can be arranged on the side of the installation port close to the room, and the lower surface of the indoor unit can be lower than the lower surface of the installation port, thereby reducing the space occupied by the window air conditioner at the installation port and reducing the obstruction of the window air conditioner to the installation port.

[0047] However, the indoor unit of the special-shaped window-type air conditioner is large in size and occupies a large amount of indoor space, which affects the use effect of the window-type air conditioner.

[0048] To address the aforementioned issues, some embodiments of the present disclosure provide a window air conditioner 1000. This window air conditioner 1000 reduces the height of the indoor unit so that its lower surface is at least higher than that of the outdoor unit. This reduces the size of the indoor unit, reducing the indoor space occupied by the indoor unit and improving the performance of the window air conditioner 1000. Furthermore, the window air conditioner 1000 can reduce obstruction of the mounting opening while avoiding affecting indoor heat exchange, thereby improving the utilization of the space at the mounting opening.

[0049] As shown in Figures 1A and 1B, a window air conditioner 1000 can be mounted on a wall 4000 having a mounting opening 3000. At least a portion of a first portion of the window air conditioner 1000 is located indoors, a second portion of the window air conditioner 1000 is located outdoors, and at least a portion of the window air conditioner 1000 is disposed within the mounting opening 3000. The mounting opening 3000 includes a window 3001, which is movable in a second direction (e.g., up and down). When the window 3001 is moved toward the window air conditioner 1000 (e.g., when the window 3001 is closed), an end of the window 3001 (e.g., the bottom end) that is closer to the window air conditioner 1000 abuts against a side of the window air conditioner 1000 (e.g., the top surface) that is closer to the window 3001.

[0050] For example, the window air conditioner 1000 is mounted on the wall 4000 via the mounting bracket 2000. The mounting bracket 2000 supports the window air conditioner 1000 on a first side (e.g., the upper side) in the second direction, and the mounting bracket 2000 is fixedly connected to the wall 4000 on a second side (e.g., the lower side) in the second direction, so that the window air conditioner 1000 can be fixed to the wall 4000 and the mounting opening 3000, thereby completing the installation of the window air conditioner 1000.

[0051] For ease of explanation, the first direction (e.g., length) in this disclosure refers to the front-to-back direction, the second direction (e.g., height) refers to the up-down direction, and the third direction (e.g., width) refers to the left-to-right direction. The first, second, and third directions are perpendicular to each other. The length, height, and width directions may be the length, height, and width directions of the window air conditioner 1000, respectively. Furthermore, the area on the side of the wall 4000 that is closer to the indoor space is referred to as the indoor side, and the area on the side of the wall 4000 that is closer to the outdoor space is referred to as the outdoor side.

[0052] In some embodiments, as shown in Figures 2A and 2B, the window air conditioner 1000 includes a housing 50. The housing 50 forms the exterior of the window air conditioner 1000, and the interior of the housing 50 is hollow to form a receiving cavity. The receiving cavity receives components of the window air conditioner 1000.

[0053] For example, the housing 50 includes a base 51 configured to support components of the window air conditioner 1000. The housing 50 also includes a cover 52. The cover 52 covers the base 51. The housing 50 also includes a panel 53, which is disposed on a side of the cover 52 that is closer to the indoor side. For example, the panel 53 is disposed on a first side (e.g., the front side) of the cover 52 in a first direction.

[0054] As shown in Figure 2A, the housing 50 also includes a first air inlet 201 (indoor air inlet). The housing 50 also includes a first air outlet 202 (indoor air outlet). The first air inlet 201 and the first air outlet 202 are arranged on the panel 53. Indoor air enters the housing 50 through the first air inlet 201 and is discharged from the first air outlet 202 to the indoor side after heat exchange, thereby regulating the indoor temperature. It should be noted that a filter element (such as filter cotton or filter mesh) can be provided at the first air inlet 201 to filter the indoor air entering the housing 50.

[0055] The housing 50 also includes a second air inlet 101 (outdoor air inlet). The housing 50 also includes a second air outlet 102 (outdoor air outlet). The second air inlet 101 and the second air outlet 102 are disposed on the outer cover 52 and communicate with the outside. The second air inlet 101 is located on the second side (e.g., the rear side) of the outer cover 52 in the first direction. Outdoor air enters the housing 50 through the second air inlet 101 and is discharged to the outside through the second air outlet 102 after heat exchange. Of course, the positions of the second air inlet 101 and the second air outlet 102 can also be interchanged.

[0056] 1A and 2C , the window type air conditioner 1000 includes an indoor unit 200. The indoor unit 200 is a first portion of the window type air conditioner 1000. At least a portion of the indoor unit 200 is located indoors.

[0057] As shown in Figures 2C and 3, the indoor unit 200 further includes a first heat exchanger 23 (indoor heat exchanger). The first heat exchanger 23 is configured to exchange heat between indoor air and a refrigerant transmitted through the first heat exchanger 23. For example, the first heat exchanger 23 operates as an evaporator in the cooling mode of the window air conditioner 1000 and operates as a condenser in the heating mode of the window air conditioner 1000.

[0058] The indoor unit 200 also includes a first fan 27 (indoor fan). The first fan 27 is configured to draw indoor air into the indoor unit 200 through a first air inlet 201 and to deliver the indoor air, after heat exchange with the first heat exchanger 23, through a first air outlet 202 of the indoor unit 200. The first fan 27 can provide power for the flow of indoor air. The first fan 27 can be a cross-flow fan.

[0059] The indoor unit 200 also includes an indoor duct member 24. A first fan 27 is disposed in the indoor duct member 24. At least a portion of the indoor duct member 24 is spaced apart from the base 51 in the second direction, thereby defining an air inlet duct 26 between the indoor duct member 24 and the base 51. The first air inlet 201 communicates with the air inlet duct 26, which in turn communicates with the air outlet duct 31. The first heat exchanger 23 is disposed within the air inlet duct 26. The indoor duct member 24 is hollow inside to form an air outlet duct 31, which communicates with the first air outlet 202. In this manner, indoor air entering the air inlet duct 26 through the first air inlet 201 exchanges heat with the first heat exchanger 23, passes through the air outlet duct 31, and flows out of the indoor unit 200 from the first air outlet 202.

[0060] It should be noted that a sound insulation member (such as sponge) may be provided between the indoor air duct member 24 and the first heat exchanger 23 to block the transmission of vibration and noise.

[0061] As shown in Figures 2C and 3, the window air conditioner 1000 further includes an outdoor unit 100. The outdoor unit 100 is the second part of the window air conditioner 1000. The outdoor unit 100 is located outdoors. The outdoor unit 100 and the indoor unit 200 are integrated and connected by pipes to transmit refrigerant.

[0062] In some examples, as shown in Figures 2B to 2D , the window air conditioner 1000 further includes a partition 40. The partition 40 is disposed between the indoor unit 200 and the outdoor unit 100, and the partition 40 is fixedly connected to the outdoor unit 100 and the indoor duct member 24. The partition 40 is configured to separate the indoor unit 200 from the outdoor unit 100.

[0063] For example, a first side (e.g., the front side) of the partition plate 40 away from the outdoor unit 100 is fixedly connected to the indoor air duct member 24, and a second side (e.g., the rear side) of the partition plate 40 close to the outdoor unit 100 is fixedly connected to the outdoor unit 100. In this way, the partition plate 40 can connect the outdoor unit 100 and the indoor unit 200 as a whole, and can separate the internal structure of the indoor unit 200 from the internal structure of the outdoor unit 100, thereby preventing the internal structures of the indoor unit 200 and the outdoor unit 100 from interfering with each other.

[0064] In addition, the partition plate 40 can not only separate the outdoor air and indoor air circulating in the window type air conditioner 1000, but also provide sound insulation.

[0065] As shown in Figures 2C and 3, the outdoor unit 100 includes a compressor 16. The compressor 16 is configured to compress the refrigerant, thereby compressing the low-pressure refrigerant into high-pressure refrigerant. The compressor 16 includes an exhaust port and a return port. Low-pressure refrigerant enters the compressor 16 through the return port. The compressor 16 compresses the low-pressure refrigerant into high-pressure refrigerant before discharging it through the exhaust port. This high-pressure refrigerant releases heat at the condenser. Then, after being decompressed, the refrigerant absorbs heat at the evaporator. Finally, the refrigerant enters the compressor 16 through the return port.

[0066] The outdoor unit 100 also includes a second heat exchanger 11 (outdoor heat exchanger). The second heat exchanger 11 is configured to exchange heat between outdoor air and the refrigerant transported through the second heat exchanger 11. For example, when the window air conditioner 1000 is in cooling mode, the second heat exchanger 11 operates as a condenser, and the exhaust port of the compressor 16 is connected to the second heat exchanger 11. When the window air conditioner 1000 is in heating mode, the second heat exchanger 11 operates as an evaporator, and the return air port of the compressor 16 is connected to the second heat exchanger 11.

[0067] The outdoor unit 100 further includes a second fan 12 (outdoor fan). The second fan 12 is configured to draw outdoor air into the outdoor unit 100 through the second air inlet 101, and to send the outdoor air after heat exchange with the second heat exchanger 11 out through the second air outlet 102. The second fan 12 provides power for the flow of outdoor air. The second fan 12 can be an axial flow fan. For example, as shown in Figures 2B and 2C, the outdoor unit 100 further includes a fan bracket 13. The fan bracket 13 is disposed on the base 51 and is fixedly connected to the base 51. The second fan 12 is disposed on the fan bracket 13, so that the fan bracket 13 can provide support for the second fan 12.

[0068] It should be noted that, since the second fan 12 is an axial flow fan and the axial flow fan is noisy, the partition 40 can soundproof the noise generated by the second fan 12 .

[0069] The outdoor unit 100 also includes an expansion valve 15 (pressure reducer). The expansion valve 15 is connected between the first heat exchanger 23 and the second heat exchanger 11. The opening of the expansion valve 15 regulates the pressure of the refrigerant flowing through the first heat exchanger 23 and the second heat exchanger 11, thereby regulating the refrigerant flow between the first heat exchanger 23 and the second heat exchanger 11.

[0070] The sequentially connected compressor 16, second heat exchanger 11, expansion valve 15, and first heat exchanger 23 form a refrigerant circuit, through which refrigerant circulates. Thus, the first heat exchanger 23 and the second heat exchanger 11 can exchange heat with indoor air and outdoor air, respectively, thereby achieving cooling mode or heating mode for the window air conditioner 1000.

[0071] The outdoor unit 100 further includes a four-way valve 14. The four-way valve 14 is disposed in the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the window type air conditioner 1000 operates in a cooling mode or a heating mode.

[0072] 2B to 2D , the window air conditioner 1000 further includes a first electrical box 41. The first electrical box 41 is connected between the fan bracket 13 and the partition 40 and is spaced apart from the base 51 in the second direction.

[0073] For example, a first end (e.g., front end) of the first electrical box 41 is fixedly connected to one end (e.g., upper end) of the partition 40 in the second direction, and a second end (e.g., rear end) of the first electrical box 41 is fixedly connected to one end (e.g., upper end) of the fan bracket 13 in the second direction. In this way, the fan bracket 13 and the partition 40 can provide a mounting point and support for the first electrical box 41, so that the first electrical box 41 can be located above the base 51 and spaced apart from the base 51.

[0074] The structure of the indoor unit 200 in some embodiments of the present disclosure is described below.

[0075] In some embodiments, as shown in FIG. 1A , at least a portion of the indoor unit 200 is located indoors, and the outdoor unit 100 is located outdoors.

[0076] In some embodiments, as shown in FIG1A , the indoor unit 200 further includes a first subunit 21 (inside the indoor unit). The indoor unit 200 further includes a second subunit 22 (outside the indoor unit). The first subunit 21 and the second subunit 22 are arranged along a first direction. The first subunit 21 extends toward the indoor side. The second subunit 22 is connected to the first subunit 21 on a first side (e.g., the front side) in the first direction, and is connected to the outdoor unit 100 on a second side (e.g., the rear side) in the first direction.

[0077] For example, the first portion of the indoor unit 200 is located indoors, while the second portion is located outdoors. The first portion of the indoor unit 200 is a first subunit 21, and the second portion of the indoor unit 200 is a second subunit 22. Furthermore, the second subunit 22 is disposed between the first subunit 21 and the outdoor unit 100.

[0078] In this case, as shown in Figures 4A to 4C, the panel 53 can be arranged on the first side (such as the front side) of the first sub-section 21 in the first direction. For example, the panel 53 is arranged on the side of the first sub-section 21 close to the indoor side. Furthermore, as shown in Figure 4A, the first fan 27 is arranged in the second sub-section 22, and the first fan 27 is separated from the first sub-section 21 by a preset distance. In this way, the first fan 27 can be located on the outdoor side and separated from the indoor side by a preset distance, thereby reducing the noise generated during the operation of the first fan 27 and improving the use effect of the window air conditioner 1000. Furthermore, by increasing the length of the indoor duct member 24, the length of the air outlet duct 31 can be increased, thereby reducing the noise generated during the operation of the first fan 27.

[0079] 4B , the cross-sectional area of ​​the first sub-portion 21 is smaller than that of the outdoor unit 100. Furthermore, the first surface (such as the lower surface) of the first sub-portion 21 in the second direction is higher than the first surface (such as the lower surface) of the outdoor unit 100 in the second direction.

[0080] For example, when viewed along a plane perpendicular to the first direction, the cross-sectional area of ​​the first subsection 21 is smaller than that of the outdoor unit 100. Alternatively, when viewed along a plane perpendicular to the third direction, the cross-sectional area of ​​the first subsection 21 is smaller than that of the outdoor unit 100. This reduces the space occupied by the indoor unit 200, reduces the area of ​​the window air conditioner 1000 obstructing the installation opening 3000, and improves the field of view at the installation opening 3000. Furthermore, a larger outdoor unit 100 helps improve the heat exchange efficiency of the window air conditioner 1000. It should be noted that the cross-sectional area of ​​the first subsection 21 can be the same as that of the second subsection 22.

[0081] In some embodiments, as shown in FIG. 4A , the cross-sectional area of ​​the first sub-portion 21 is smaller than the cross-sectional area of ​​the second sub-portion 22 .

[0082] For example, when a plane perpendicular to the first direction is used as a cross section, the cross-sectional area of ​​the first sub-section 21 is smaller than the cross-sectional area of ​​the second sub-section 22. Alternatively, when a plane perpendicular to the third direction is used as a cross section, the cross-sectional area of ​​the first sub-section 21 is smaller than the cross-sectional area of ​​the second sub-section 22.

[0083] This reduces the space occupied by the indoor unit 200 indoors, reduces the area of ​​the window air conditioner 1000 obstructing the installation opening 3000, and improves the field of view at the installation opening 3000. Furthermore, by reducing the cross-sectional area of ​​the first subsection 21, the flow rate of indoor air in the first subsection 21 can be increased, helping to improve the heat exchange efficiency of the first heat exchanger 23, thereby enhancing the cooling or heating performance of the window air conditioner 1000. This also reduces the resistance of the window air conditioner 1000 to the indoor air, lowering the power consumption of the first fan 27 and improving energy efficiency. Furthermore, the second subsection 22 with a larger cross-sectional area can correspond to the outdoor unit 100, thereby improving the overall coordination of the window air conditioner 1000.

[0084] As shown in Figures 4A and 4C, the first surface of the first subsection 21 is higher than the first surface (i.e., the lower surface) of the second subsection 22 in the second direction. Thus, there is a height difference between the first surface of the first subsection 21 and the first surface of the second subsection 22. This allows the first portion of the lower profile of the orthographic projection of the indoor unit 200 on a plane perpendicular to the third direction to extend in the first direction and the second portion to extend in the second direction, with the first portion of the lower profile being perpendicular to the second portion of the lower profile.

[0085] In this case, a first step 5126 can be formed at the junction of the first surface of the first sub-section 21 and the first surface of the second sub-section 22. The first step 5126 can abut against the side of the installation opening 3000 that is closer to the outdoor side (such as a windowsill). The first sub-section 21 is mated with the installation opening 3000, and a portion of the first surface of the second sub-section 22 protrudes relative to the first surface of the first sub-section 21. In this way, the first surface of the second sub-section 22 can be lower than the first surface of the installation opening 3000 in the second direction (such as the lower surface), and a portion of the second sub-section 22 can abut against the wall 4000, thereby reducing the space occupied by the first sub-section 21 in the room, reducing the field of view blocked by the indoor unit 200, and improving the field of view at the installation opening 3000.

[0086] It should be noted that, in FIG. 4B , the first surface of the first sub-section 21 and the first surface of the outdoor unit 100 may also form a first step 5126 .

[0087] In some embodiments, as shown in Figure 4A, when the first surface of the first sub-section 21 is higher than the first surface of the second sub-section 22, the first surface of the second sub-section 22 can be flush with the first surface of the outdoor unit 100, so that the first surface of the first sub-section 21 can be higher than the first surface of the outdoor unit 100.

[0088] In this way, with the plane perpendicular to the third direction as the cross-section, the first part of the lower contour of the cross-section of the window air conditioner 1000 can extend along the first direction, and the second part can extend along the second direction, and the first part of the lower contour is perpendicular to the second part of the lower contour, thereby reducing the space occupied by the first sub-section 21 in the room, reducing the field of view blocked by the indoor unit 200, and improving the field of view at the installation port 3000.

[0089] Moreover, by making the first surface of the first sub-section 21 higher than the first surface of the second sub-section 22, the accommodating space of the second sub-section 22 can be increased, and the height of the first sub-section 21 can be further reduced, thereby further reducing the space occupied by the first sub-section 21 on the indoor side, further reducing the field of view blocked by the indoor unit 200, and further improving the field of view at the installation port 3000.

[0090] In some embodiments, as shown in FIG4C , the second surface (e.g., the upper surface) of the first subsection 21 in the second direction is lower than the second surface (e.g., the upper surface) of the second subsection 22 in the second direction. Thus, there is a height difference between the second surface of the first subsection 21 and the second surface of the second subsection 22. As a result, the first portion of the upper profile of the orthographic projection of the indoor unit 200 on a plane perpendicular to the third direction can extend in the first direction, while the second portion can extend in the second direction, with the first portion of the upper profile being perpendicular to the second portion of the upper profile.

[0091] In this case, a second step 5127 can be formed at the junction of the second surface of the first sub-section 21 and the second surface of the second sub-section 22. The second step 5127 can abut against the window frame 3002 of the window 3001, and a portion of the second surface of the second sub-section 22 protrudes relative to the second surface of the first sub-section 21. In this way, the second surface of the second sub-section 22 is higher than the second surface of the first sub-section 21, and a portion of the second sub-section 22 can abut against the window frame 3002, thereby reducing the space occupied by the first sub-section 21 indoors, reducing the field of view obstructed by the indoor unit 200, and improving the field of view at the installation opening 3000.

[0092] In some embodiments, as shown in FIG4C , a height difference H1 between the second surface of the first sub-section 21 and the second surface of the second sub-section 22 is less than a predetermined threshold. For example, the predetermined threshold is less than or equal to a height H2 of the window frame 3002, such that the height difference H1 between the second surface of the first sub-section 21 and the second surface of the second sub-section 22 is less than the height H2 of the window frame 3002 (i.e., H2>H1).

[0093] In this way, compared with the situation where the second surface of the first sub-section 21 is flush with the second surface of the second sub-section 22, by using the space blocked by the window frame 3002 for the size design of the second sub-section 22, the accommodating space of the second sub-section 22 can be further increased, the height of the first sub-section 21 can be further reduced, and the field of view blocked by the window air conditioner 1000 can be reduced.

[0094] Corresponding to the first subsection 21 and the second subsection 22 , the first heat exchanger 23 in some embodiments of the present disclosure may be arranged tilted.

[0095] In some embodiments, as shown in Figures 4A to 4C , the first heat exchanger 23 includes a plate heat exchanger and is tilted away from the outdoor unit 100. A first end (e.g., the upper end) of the first heat exchanger 23 in the second direction is farther from the outdoor unit 100 than a second end (e.g., the lower end) of the first heat exchanger 23 in the second direction. The first heat exchanger 23 is disposed in at least one of the first subsection 21 or the second subsection 22.

[0096] In some examples, as shown in FIG4C , the first portion of the first heat exchanger 23 is disposed in the first subsection 21, and the second portion of the first heat exchanger 23 is disposed in the second subsection 22. For example, the first heat exchanger 23 extends from the second subsection 22 to the first subsection 21, and the first end of the first heat exchanger 23 abuts the first end (e.g., the upper end) of the air inlet duct 26 in the second direction, while the second end of the first heat exchanger 23 abuts the second end (e.g., the lower end) of the air inlet duct 26 in the second direction. The air inlet duct 26 will be described later.

[0097] This facilitates reducing the height and volume of the first subsection 21, thereby reducing the volume of the window air conditioner 1000 and lowering product costs. It also reduces the space occupied by the window air conditioner 1000 within the window 3001, improving the field of view at the installation opening 3000. Furthermore, it increases the contact area between the first heat exchanger 23 and the indoor air, improving the heat exchange efficiency of the window air conditioner 1000.

[0098] In addition, by tilting the first heat exchanger 23, the condensed water on the first heat exchanger 23 can be easily guided to the water collection tank or drain outlet, which can reduce the residence time of the condensed water on the first heat exchanger 23 and reduce the air humidity of the indoor unit 200, thereby reducing the speed of condensed water generation and avoiding water leakage of the window air conditioner 1000.

[0099] It should be noted that the plate heat exchanger has a compact structure, simple design, and small footprint, making it easy to maintain and clean. Furthermore, since the inclined first heat exchanger 23 occupies a large space, the compact plate heat exchanger can improve space utilization within the indoor unit 200. Furthermore, by locating part of the first heat exchanger 23 in the second subsection 22, outdoor temperature can be used to reduce the heat in the second subsection 22, thereby reducing the heat load on the second subsection 22.

[0100] In other examples, as shown in FIG4B , the first heat exchanger 23 is entirely located in the second subsection 22. This increases the size of the first subsection 21 in the first direction (e.g., length) while decreasing the size of the first subsection 21 in the second direction (e.g., height). This reduces the space occupied by the window air conditioner 1000 on the window 3001, improves the field of view at the installation opening 3000, and enhances the performance of the window air conditioner 1000. Furthermore, the cooling effect of the outdoor temperature on the indoor unit 200 during operation can be further enhanced.

[0101] It is understandable that the first heat exchanger 23 may also be entirely located in the first sub-section 21 to improve the compactness of the indoor unit 200 and reduce the overall volume of the window air conditioner 1000 .

[0102] In some embodiments, as shown in Figures 5A to 5D, the indoor air duct member 24 includes a first volute 241 (air inlet volute). The first volute 241 is disposed adjacent to the first heat exchanger 23. The first volute 241 extends substantially along the second direction.

[0103] The indoor air duct member 24 also includes a second volute 242 (an outlet volute). The second volute 242 extends generally along the first direction, and the outlet air duct 31 is disposed within the second volute 242. The first volute 241 and the second volute 242 are connected, and the first fan 27 is disposed between the first volute 241 and the second volute 242.

[0104] For example, the first volute 241 and the second volute 242 are connected, so that a space for accommodating the first fan 27 can be defined between the first volute 241 and the second volute 242. In this way, after the indoor air enters the air inlet duct 26 and exchanges heat with the first heat exchanger 23, the first fan 27 can drive the heat exchange air flow from the first volute 241 into the second volute 242 and into the indoor side through the air outlet duct 31.

[0105] It should be noted that by increasing the length of the indoor air duct component 24 (such as the second volute 242), the length of the air inlet duct 26 and the air outlet duct 31 can be increased, thereby increasing the heat exchange time of the indoor air in the indoor unit 200 and improving the cooling or heating effect of the window air conditioner 1000.

[0106] In some embodiments, as shown in Figures 5A, 5C, and 5D, the indoor duct member 24 further includes a partition 246 (partition rib). The partition 246 is disposed within the second volute 242 and located within the outlet duct 31. The partition 246 extends along the first direction and is configured to divide the outlet duct 31 into a plurality of sub-outlet ducts 310 along the third direction.

[0107] For example, the partition 246 is plate-shaped. The partition 246 extends from front to back within the outlet duct 31 and also extends in the second direction. Thus, the partition 246 can divide the outlet duct 31 into multiple sub-outlet ducts 310 in the third direction. This allows the heat-exchanged airflow to flow out of the outlet duct 31 evenly in the third direction, improving the cooling or heating performance of the window air conditioner 1000. Furthermore, the partition 246 enhances the structural strength of the indoor duct member 24, preventing collapse of the outlet duct 31.

[0108] In some embodiments, the indoor duct member 24 may include a plurality of partitions 246 to further improve the uniformity of the heat exchange airflow flowing out of the indoor unit 200 .

[0109] 5A, 5B, and 5D, the second volute 242 includes a volute portion 243. The volute portion 243 extends substantially along the second direction and is connected to the first volute 241 to define a space for accommodating the first fan 27 therebetween.

[0110] The indoor air duct member 24 further includes an air duct portion 244 . The air duct portion 244 extends along a first direction and is connected to the volute portion 243 .

[0111] The indoor air duct member 24 also includes a plurality of reinforcing plates 247 (connecting ribs). These reinforcing plates 247 are disposed at the junction of the air duct portion 244 and the volute portion 243. These reinforcing plates 247 extend in the first direction and are spaced apart in the third direction. These reinforcing plates 247 are configured to increase the connection strength between the volute portion 243 and the air duct portion 244, thereby preventing cracking at the junction between the volute portion 243 and the air duct portion 244.

[0112] For example, the indoor air duct member 24 includes two reinforcing plates 247 . A first end of the reinforcing plate 247 is connected to the air duct portion 244 , and a second end thereof is connected to the volute portion 243 .

[0113] In some embodiments, as shown in FIG5C , one side of the indoor duct member 24 facing the first heat exchanger 23 extends along the inclination of the first heat exchanger 23 to form a second inclined surface 303. The second inclined surface 303 is fixedly connected to the first heat exchanger 23. In this way, the second inclined surface 303 can adapt to the inclined first heat exchanger 23 to avoid a gap at the connection between the first heat exchanger 23 and the indoor duct member 24. This can reduce the loss of indoor air when entering the indoor duct member 24 and increase the air volume entering the indoor duct member 24. Furthermore, it can prevent outdoor air from entering the indoor duct member 24 and affecting the heat exchange efficiency of the window air conditioner 1000.

[0114] In some embodiments, as shown in FIG5E , the indoor duct member 24 further includes a fixing portion 32 (mounting protrusion). The fixing portion 32 is disposed on a surface of the second volute 242 near the base 51 (e.g., the lower surface) and protrudes from the lower surface of the second volute 242. The fixing portion 32 may be a protrusion.

[0115] In this case, the indoor unit 200 further includes a sealing member (seal member) disposed on one side (e.g., the rear side) of the fixing portion 32 in the first direction and abutting against the first heat exchanger 23. Thus, the fixing portion 32 and the sealing member seal the connection between the first heat exchanger 23 and the indoor air duct member 24, thereby preventing leakage of the heat exchange airflow within the first heat exchanger 23 and preventing foreign matter, dust, etc. from entering the first heat exchanger 23 and affecting the operation of the window air conditioner 1000.

[0116] In some embodiments, the sealing member may be made of rubber or foam.

[0117] In some embodiments, as shown in Figures 6A to 6C , the indoor duct member 24 further includes a mounting plate 35. The mounting plate 35 is disposed on one side (e.g., the right side) of the second volute 242 in the third direction and is spaced apart from the base 51. In this case, the indoor unit 200 further includes a second electrical box 42 (indoor control box), which is disposed on the mounting plate 35.

[0118] The mounting plate 35 provides a sturdy support platform for the second electrical box 42, preventing it from loosening or moving during transportation, installation, or use, thereby improving the stability and reliability of the electronic components in the second electrical box 42. Furthermore, the connection between the mounting plate 35 and the indoor air duct member 24 improves the stability of the mounting plate 35 and helps reduce vibration and noise generated by the second electrical box 42 during operation.

[0119] In some embodiments, as shown in Figures 5E and 6A, the indoor duct member 24 further includes a third flange 350 (limiting flange). The third flange 350 is provided at the edge of the mounting plate 35 to limit the position of the second electrical box 42 and prevent the second electrical box 42 from moving.

[0120] The following describes the base 51 for supporting the internal components of the window air conditioner 1000 in some embodiments of the present disclosure.

[0121] In some embodiments, as shown in Figures 2B to 2D , the base 51 includes a first base 511 (outdoor base). The first base 511 and the first portion of the outer cover 52 form the housing (first housing) of the outdoor unit 100. The compressor 16, the second heat exchanger 11, and the fan bracket 13 are mounted on the first base 511.

[0122] The base 51 also includes a second base 512. The second base 512 and the second portion of the outer cover 52 form the housing (second housing) of the indoor unit 200, and the second base 512 is connected to the first base 511. For example, as shown in FIG2B , the first base 511 includes an extension 5111. The extension 5111 extends in a first direction toward the first subsection 21, and the second base 512 is fixedly connected to the extension 5111.

[0123] The second base 512 contacts the windowsill to support the indoor unit 200, protect the internal components of the indoor unit 200, and improve the stability of the window air conditioner 1000. In addition, during the operation of the indoor unit 200, the second base 512 can also reduce the possibility of vibration being transmitted to the wall 4000, thereby reducing noise.

[0124] In this case, the indoor duct member 24 is disposed on the second base 512, and at least a portion of the indoor duct member 24 is spaced apart from the second base 512 in the second direction, thereby defining an air inlet duct 26 between the indoor duct member 24 and the second base 512. For example, the indoor duct member 24 is connected to the second base 512, and the second volute 242 is spaced apart from the second base 512 to define the air inlet duct 26. The first heat exchanger 23 is disposed between the second base 512 and the indoor duct member 24. In this manner, indoor air enters the air inlet duct 26 from the first air inlet 201, exchanges heat with the refrigerant at the first heat exchanger 23, and then enters the air outlet duct 31. The heat-exchanged indoor air then enters the room through the first air outlet 202, thereby regulating the indoor temperature and achieving a cooling mode or a heating mode for the window air conditioner 1000.

[0125] 2B to 2D , the second base 512 includes a first sub-base 5121 . The first sub-base 5121 is part of the first sub-portion 21 .

[0126] The second base 512 also includes a second sub-base 5122. The second sub-base 5122 is part of the second sub-section 22. The second sub-base 5122 is connected to the first sub-base 5121 and the outdoor unit 100. For example, a first end of the second sub-base 5122 is connected to the first sub-base 5121, and a second end of the second sub-base 5122 is connected to the extension 5111. In this case, the first sub-base 5121 is located on a side of the second sub-base 5122 away from the outdoor unit 100 (e.g., the front side).

[0127] The first surface of the first sub-base 5121 in the second direction (e.g., the lower surface) is higher than the second sub-base 5122, and thus the first surface of the second sub-base 5122 in the second direction (e.g., the lower surface) is lower than the first surface of the first sub-base 5121. This creates a height difference between the first surface of the first sub-base 5121 and the first surface of the second sub-base 5122. This allows the first portion of the lower contour of the orthographic projection of the second base 512 on a plane perpendicular to the third direction to extend in the first direction, while the second portion can extend in the second direction. The first portion of the lower contour is perpendicular to the second portion of the lower contour, thereby facilitating the second base 512 to conform to the contour of the windowsill and improving the stability of the window air conditioner 1000 after installation. In this case, the first surface of the first sub-base 5121 and the first surface of the second sub-base 5122 connect to form a first step 5126.

[0128] In some embodiments, as shown in Figures 7A to 7C , the second base 512 further includes a connecting portion 5125. The connecting portion 5125 is disposed between the first sub-base 5121 and the second sub-base 5122, and connects the first sub-base 5121 and the second sub-base 5122. The connecting portion 5125 is inclined in a direction away from the outdoor unit 100, and the inclination angle of the connecting portion 5125 is substantially the same as the inclination angle of the first heat exchanger 23. Here, the inclination angle can be understood as the angle between the extension direction of the corresponding component and the second direction or the first direction.

[0129] This reduces the material requirements of the base 51, lowering production costs and facilitating the flow of indoor air through the first heat exchanger 23. Furthermore, the contact area and tightness between the second base 512 and the window sill are increased, improving the stability of the window air conditioner 1000 after installation. It should be noted that the first step 5126 includes a connecting portion 5125.

[0130] In some embodiments, as shown in FIG4C , the first heat exchanger 23 and the connecting portion 5125 are parallel to each other and spaced apart. This increases the contact area between the indoor air entering the air inlet duct 26 and the first heat exchanger 23, thereby improving the heat exchange effect of the first heat exchanger 23.

[0131] If the shortest distance D between the first heat exchanger 23 and the connection portion 5125 is less than 15 mm, the gap between the first heat exchanger 23 and the connection portion 5125 is small, and the flow of indoor air is hindered, affecting the heat exchange efficiency of the first heat exchanger 23. If the shortest distance D between the first heat exchanger 23 and the connection portion 5125 is greater than 25 mm, the gap between the first heat exchanger 23 and the connection portion 5125 is large, and the indoor air cannot be concentrated near the first heat exchanger 23, affecting the heat exchange efficiency of the first heat exchanger 23.

[0132] In some embodiments, as shown in FIG2D , the shortest distance D between the first heat exchanger 23 and the connection portion 5125 is greater than or equal to 15 mm and less than or equal to 25 mm (i.e., 15 mm ≤ D ≤ 25 mm). For example, the shortest distance D is 15 mm, 17 mm, 19 mm, 21 mm, 23 mm, or 25 mm. This allows for smooth circulation of indoor air and saves material. Here, the shortest distance D can be understood as the shortest distance between the surface of the first heat exchanger 23 near the connection portion 5125 and the connection portion 5125.

[0133] In some embodiments, as shown in Figures 7A and 7B, the base 51 also includes a sub-water guide 254. The sub-water guide 254 is arranged on the second base 512 and extends approximately along the first direction. The sub-water guide 254 is configured to guide the condensed water generated by the first heat exchanger 23. For example, the sub-water guide 254 is a water guide groove. The sub-water guide 254 is arranged on a side (such as the upper side) of the first sub-base 5121, the connecting portion 5125 and the second sub-base 5122 close to the first heat exchanger 23. The first part of the sub-water guide 254 is arranged on the first sub-base 5121, the second part of the sub-water guide 254 is arranged on the connecting portion 5125, and the third part of the sub-water guide 254 is arranged on the second sub-base 5122. Through the inclined connecting portion 5125, the condensed water can be diverted and the drainage efficiency of the condensed water can be improved.

[0134] The base 51 also includes a first water collection portion 258. The first water collection portion 258 is disposed on the second base 512. The first water collection portion 258 is located on a side of the sub-water guide portion 254 that is closer to the outdoor unit 100 (e.g., the rear side) and is in communication with the sub-water guide portion 254. The first water collection portion 258 is configured to collect condensed water guided by the sub-water guide portion 254. The first water collection portion 258 can be a water collection trough. Furthermore, in the second direction, the first water collection portion 258 is lower than the sub-water guide portion 254.

[0135] When the window air conditioner 1000 is in cooling mode, the first heat exchanger 23 functions as an evaporator. After indoor air enters the air inlet duct 26, it exchanges heat with the refrigerant at the first heat exchanger 23. During this process, water in the indoor air condenses into condensed water and adheres to the surface of the first heat exchanger 23. Under the influence of gravity, this condensed water drips from the first heat exchanger 23 to the sub-water guide 254, from which it flows to the first water collection section 258. The first water collection section 258 collects the condensed water and discharges it out of the indoor unit 200, thereby preventing water leakage in the window air conditioner 1000 and preventing it from flowing into other components within the indoor unit 200 and causing damage.

[0136] In some embodiments, in the first direction, the length of the orthographic projection of the sub-water guide 254 on the second base 512 is greater than the length of the orthographic projection of the first heat exchanger 23 on the second base 512. In this way, condensed water at the first heat exchanger 23 can drip into the sub-water guide 254, preventing the condensed water from dripping outside the sub-water guide 254 and causing water leakage in the window air conditioner 1000.

[0137] In some embodiments, as shown in Figures 7A and 7B, the base 51 further includes a plurality of first baffles 255. The plurality of first baffles 255 are disposed on the second base 512, and the plurality of first baffles 255 protrude from the second surface (such as the upper surface) of the second base 512 in the second direction. The plurality of first baffles 255 are spaced apart in the third direction and extend along the first direction. In this way, a sub-water guide 254 can be formed between two adjacent first baffles 255, so that the first baffle 255 can divert and guide the condensed water so that the condensed water in the sub-water guide 254 flows along the extension direction of the first baffle 255 to the first water collecting portion 258, thereby improving the drainage efficiency of the condensed water. In addition, the plurality of first baffles 255 can also improve the structural strength of the second base 512.

[0138] 7A and 7B , the base 51 further includes a second baffle 256. The second baffle 256 is disposed on the second base 512 and protrudes from the second surface of the second base 512. The second baffle 256 extends to the edge of the second base 512 along the third direction.

[0139] For example, the second baffle 256 extends from a first end (e.g., the left end) of the second base 512 in the third direction to a second end (e.g., the right end) of the second base 512 in the third direction. Furthermore, the second baffle 256 is disposed perpendicular to the first baffle 255, and thus perpendicular to the sub-water guide 254. In this manner, the second baffle 256 can block condensation, preventing it from entering the room through the first air inlet 201 and causing water leakage in the window air conditioner 1000.

[0140] In some embodiments, the orthographic projection of the first heat exchanger 23 on the second base 512 is located on a side of the second baffle 256 that is closer to the outdoor unit 100 (e.g., the rear side). Thus, the orthographic projection of the first heat exchanger 23 on the second base 512 that is closer to the indoor side (e.g., the front side) cannot extend beyond the second baffle 256. Thus, condensed water on the first heat exchanger 23 can drip into the sub-water guide 254, preventing the condensed water from dripping outside the sub-water guide 254 and preventing water leakage in the window air conditioner 1000.

[0141] In some embodiments, as shown in Figures 7A and 7B, the base 51 further includes a third baffle 257 (water retaining rib). The third baffle 257 is disposed on the second sub-base 5122 and extends along the third direction. The third baffle 257 is located on the rear side of the sub-water guide 254 and at the second end of the first heat exchanger 23. The first water collection portion 258 can be located on one side (such as the left or right side) of the third baffle 257 in the third direction. The third baffle 257 is configured to guide the condensed water generated by the first heat exchanger 23 so that the condensed water flows into the first water collection portion 258 and is discharged through the first water collection portion 258.

[0142] For example, the base 51 includes two third baffles 257, which are respectively located on both sides of the first water collecting portion 258 in the third direction. The two third baffles 257 guide the condensed water into the first water collecting portion 258 to improve the discharge efficiency of the condensed water.

[0143] In some embodiments, as shown in Figures 7A and 7B, the base 51 further includes a guide portion 259 (guide hole). The guide portion 259 is disposed on the second base 512. The guide portion 259 connects the first water collecting portion 258 and the outdoor unit 100 and is located at the lowest point of the first water collecting portion 258 in the second direction. For example, the guide portion 259 is a through hole that connects the first water collecting portion 258 and the outdoor unit 100. In this way, the condensed water generated at the first heat exchanger 23 can flow into the first water collecting portion 258 after dripping onto the first sub-base 5121, the connecting portion 5125, and the second sub-base 5122, and then flow into the outdoor unit 100 through the guide portion 259.

[0144] In some embodiments, as shown in Figures 6C and 7C, the base 51 further includes a second water collection portion 5112. The second water collection portion 5112 is disposed on the first base 511 and communicates with the first water collection portion 258. The second water collection portion 5112 is configured to collect condensed water. For example, the second water collection portion 5112 is a water collection trough. The water collection trough is disposed on the extension portion 5111 and communicates with the first water collection portion 258 via the guide portion 259, thereby collecting condensed water from the first water collection portion 258.

[0145] For example, the first base 511 is located on one side (e.g., the lower side) of the second base 512 in the second direction. In this way, the condensed water in the first water collecting portion 258 can flow into the second water collecting portion 5112 of the first base 511 under the action of gravity, so that the condensed water in the indoor unit 200 can be discharged into the outdoor unit 100.

[0146] 7A , the base 51 further includes a first positioning portion 5113. The first positioning portion 5113 is disposed on the first base 511 and close to the indoor unit 200. For example, the first positioning portion 5113 is disposed on the extension portion 5111.

[0147] In this case, the base 51 further includes a second positioning portion. The second positioning portion is disposed on the second base 512. The first positioning portion 5113 is connected to the second positioning portion for positioning.

[0148] For example, when installing the window air conditioner 1000, the second base 512 is installed from top to bottom on the first base 511. In this process, the first positioning portion 5113 and the second positioning portion can be connected to each other for positioning, thereby achieving a preliminary connection between the second base 512 and the first base 511.

[0149] In some embodiments, one of the first positioning portion 5113 and the second positioning portion may be a through hole, and the other of the first positioning portion 5113 and the second positioning portion may be a positioning post that can be inserted into the through hole for positioning.

[0150] In some embodiments, the base 51 may include multiple first positioning portions 5113. Correspondingly, the base 51 may also include multiple second positioning portions. The multiple first positioning portions 5113 correspond to the multiple second positioning portions, respectively, to further improve the assembly accuracy of the second base 512 and the first base 511.

[0151] 7A , the base 51 further includes a first mounting portion 5114. The first mounting portion 5114 is disposed on the first base 511 and close to the indoor unit 200. For example, the first mounting portion 5114 is disposed on the extension portion 5111.

[0152] In this case, the base 51 further includes a second mounting portion 5128. The second mounting portion 5128 is disposed on the second base 512. The first mounting portion 5114 and the second mounting portion 5128 are fixedly connected.

[0153] For example, the first mounting portion 5114 and the second mounting portion 5128 are correspondingly arranged, and the first mounting portion 5114 and the second mounting portion 5128 are engaged with each other, so that the second base 512 and the first base 511 are connected.

[0154] In some embodiments, one of the first mounting portion 5114 and the second mounting portion 5128 may be a buckle, and the other of the first mounting portion 5114 and the second mounting portion 5128 may be a slot, wherein the buckle engages with the slot to securely connect the first base 511 to the second base 512. Alternatively, the first mounting portion 5114 and the second mounting portion 5128 may have through holes, and the first mounting portion 5114 and the second mounting portion 5128 may be securely connected via fasteners (e.g., bolts) to improve the stability of the connection between the first base 511 and the second base 512.

[0155] In some embodiments, as shown in FIG7A , the base 51 includes a plurality of first mounting portions 5114. Correspondingly, the base 51 includes a plurality of second mounting portions 5128. The plurality of first mounting portions 5114 correspond to and are fixedly connected to the plurality of second mounting portions 5128, respectively, to further enhance the connection strength between the second base 512 and the first base 511.

[0156] 8 and 9A , the second base 512 further includes a bottom plate 5123 . The first baffle 255 , the second baffle 256 , the sub-water guide 254 , and the first water collecting portion 258 are disposed on the bottom plate 5123 .

[0157] The second base 512 also includes two side panels 5124. The side panels 5124 are disposed on a side (e.g., the upper side) of the bottom plate 5123 facing the indoor duct member 24 and are spaced apart in the third direction. The bottom plate 5123, the two side panels 5124, and the indoor duct member 24 define an air inlet duct 26.

[0158] In some embodiments, as shown in Figures 5C and 6C , the two side panels 5124 extend toward one side of the first heat exchanger 23 along the inclination of the first heat exchanger 23 to form a first inclined surface 302. The first inclined surface 302 is fixedly connected to the first heat exchanger 23. In this way, the first inclined surface 302 can be adapted to the first heat exchanger 23 to avoid a gap at the connection between the first heat exchanger 23 and the side panels 5124, thereby improving the sealing of the air inlet duct 26, thereby improving the heat exchange efficiency between the indoor air and the first heat exchanger 23 and reducing heat loss during the heat exchange process.

[0159] In some embodiments, as shown in FIG9A , the second base 512 further includes a first water guide 51231 (main water channel). The first water guide 51231 is formed between the two side panels 5124 and the bottom panel 5123. The first water guide 51231 is configured to collect and guide condensed water generated by the first heat exchanger 23. The first water guide 51231 extends generally along a first direction. Condensed water dripping from the first heat exchanger 23 flows into the first water guide 51231 and is discharged from the indoor unit 200 through the first water guide 51231, thereby preventing the condensed water from dripping to other locations and causing damage to other electronic components. It will be understood that the first water guide 51231 includes a sub-water guide 254 and a first water collection portion 258.

[0160] In some embodiments, as shown in FIG9A , the second base 512 further includes a first flange 51232 . The first flange 51232 is disposed at an edge of the bottom plate 5123 and extends along the second direction. The first flange 51232 is spaced apart from the side plate 5124 , thereby allowing a gap to exist between the edges of the side plate 5124 and the bottom plate 5123 .

[0161] The second base 512 also includes a second water guide 51233 (auxiliary water guide trough). The second water guide 51233 is configured to collect and guide condensed water. The first flange 51232 and the side plate 5124 are spaced apart to form the second water guide 51233. The second water guide 51233 is connected to the first water guide 51231. The second water guide 51233 is located on one side of the first heat exchanger 23 in the third direction to enhance the drainage effect of the condensed water. When the first water guide 51231 does not drain well or the condensed water overflows due to other reasons, the second water guide 51233 can receive and guide the condensed water, thereby reducing the risk of water leakage and improving the operating efficiency of the window air conditioner 1000.

[0162] It should be noted that the mounting plate 35 is located on the side (upper side) of the second water guide 51233 away from the second base 512. Thus, by placing the mounting plate 35 above the second water guide 51233, the second electrical box 42 can be kept away from condensed water, thereby preventing condensed water from intruding into the second electrical box 42 and damaging the electronic components therein.

[0163] The following describes the closed structure of the first heat exchanger 23 in some embodiments of the present disclosure.

[0164] 8 and 9A , the indoor unit 200 further includes two connection plates 33. The two connection plates 33 are respectively connected to both sides of the first heat exchanger 23 in the third direction.

[0165] The connecting plate 33 is connected to the indoor air duct member 24 on a first side (e.g., the upper side) in the second direction, and is connected to the second base 512 on a second side (e.g., the lower side) in the second direction. For example, the lower side of the connecting plate 33 is fixedly connected to the side plate 5124 and is disposed on a side of the side plate 5124 facing the first flange 51232.

[0166] The connecting plate 33 secures the first heat exchanger 23 to the second base 512, preventing vibration or deformation of the first heat exchanger 23, thereby improving the stability of the window air conditioner 1000. This also prevents heat exchange airflow from escaping from both sides of the first heat exchanger 23, thereby improving heat exchange efficiency. Furthermore, the connecting plate 33 facilitates installation and maintenance of the first heat exchanger 23, helping to accurately position and secure the first heat exchanger 23 during installation and maintenance.

[0167] 9B , the second base 512 further includes a first position-limiting portion 34. The first position-limiting portion 34 is disposed on one side of the side plate 5124 in the third direction.

[0168] In this case, the connecting plate 33 includes a second limiting portion 36. The first limiting portion 34 and the second limiting portion 36 are connected to each other so as to fix the connecting plate 33 and the second base 512 and limit the connecting plate 33.

[0169] For example, the first limiting portion 34 includes a limiting rib that protrudes from the side plate 5124. The connecting plate 33 includes a limiting groove. The portion of the connecting plate 33 near the first limiting portion 34 is recessed to form the limiting groove. The limiting rib and the limiting groove are plugged into each other.

[0170] The second stopper 36 cooperates with the first stopper 34 to improve the positioning accuracy when the side panel 5124 and the connecting plate 33 are connected, thereby improving assembly efficiency. In addition, the first stopper 34 can also limit the movement of the connecting plate 33, thereby improving the stability of the window air conditioner 1000.

[0171] In some embodiments, the indoor unit 200 satisfies one of the following conditions:

[0172] The indoor unit 200 also includes a first sealing plate (first sealing plate). The first sealing plate is disposed on a first side (e.g., the front side) of the connecting plate 33 in a first direction. The first sealing plate, the second base 512, and the indoor duct member 24 form a closed structure to seal the air inlet duct 26.

[0173] Alternatively, the indoor unit 200 further includes a second sealing plate (second sealing plate). The second sealing plate is disposed on a second side (e.g., a rear side) of the connecting plate 33 in the first direction. The second sealing plate, the second base 512, and the indoor duct member 24 form a closed structure to seal the air inlet duct 26.

[0174] The first and second closing panels can be perpendicularly connected to the connecting plate 33. Since the side panels 5124 or the indoor duct member 24 are connected parallel to the connecting plate 33, gaps may exist at the junctions between the side panels 5124 and the indoor duct member 24 and the connecting plate 33. In this case, by installing closing panels on the front and rear sides of the connecting plate 33, the gaps can be sealed, preventing indoor air from escaping through them, reducing heat loss, and improving the energy efficiency of the window air conditioner 1000. This also helps reduce noise generated during operation of the window air conditioner 1000, thereby improving the performance of the window air conditioner 1000.

[0175] In some embodiments, as shown in FIG9A , the base 51 further includes a second flange 38 . The second flange 38 is disposed on a side of the second base 512 close to the first heat exchanger 23 , and the first heat exchanger 23 abuts the second flange 38 . Thus, on the one hand, by providing the second flange 38 , the structural strength of the first heat exchanger 23 can be improved, preventing the first heat exchanger 23 from deforming or vibrating during operation, thereby reducing the risk of mechanical failure. On the other hand, by providing the second flange 38 , the air inlet duct 26 can be further sealed, preventing the heat exchange airflow from overflowing through the gap, reducing heat loss, and improving the energy efficiency of the window air conditioner 1000 . Furthermore, it also helps to reduce the noise generated during the operation of the window air conditioner 1000 and improve the use effect of the window air conditioner 1000 .

[0176] In some embodiments, as shown in FIG6B , the connecting plate 33 includes a body 330. The connecting plate 33 also includes a first hole 331. The first hole 331 is provided on a side of the body 330 close to the indoor duct member 24 (eg, an upper side).

[0177] 5E , the indoor duct member 24 further includes a second hole 248 . The second hole 248 is provided in the first volute 241 and corresponds to the first hole 331 .

[0178] Window air conditioner 1000 also includes a first fastener. The first fastener (e.g., a bolt) can pass through first hole 331 and second hole 248 to securely connect connecting plate 33 to indoor duct member 24. This improves the integrity of window air conditioner 1000 and reduces noise generated during operation.

[0179] 6B , the connecting plate 33 further includes a third hole 332. The third hole 332 is disposed on a side of the body 330 close to the second base 512 (eg, a lower side).

[0180] In this case, the second base 512 further includes a fourth hole 263 . The fourth hole 263 is provided on the side plate 5124 and is corresponding to the third hole 332 .

[0181] Window air conditioner 1000 also includes a second fastener. The second fastener (e.g., a bolt) can be inserted through third hole 332 and fourth hole 263 to securely connect connecting plate 33 and side plate 5124. This improves the integrity of window air conditioner 1000 and reduces noise generated during operation.
