Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a window air conditioner. Background Technology

[0002] In window air conditioners of related technologies, the outdoor unit includes a heat exchanger and a fan. The fan is usually located upstream of the heat exchanger and supported by a duct cover. However, if the fan is located downstream of the heat exchanger, its position is relatively outward and it cannot obtain the support of the heat exchanger, making it prone to shaking. Under certain circumstances, it is easy to collide with nearby components and cause damage. Therefore, the fan is usually not located downstream of the heat exchanger. Utility Model Content

[0051] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0052] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0053] Hereinafter, with reference to the accompanying drawings, a window air conditioner 100 according to an embodiment of the present invention will be described.

[0054] refer to Figure 1 and Figure 2 The window air conditioner 100 includes an outdoor unit 1, which includes a heat exchanger 11 and a fan 12 arranged sequentially along a first direction F1, where F1 is horizontal. The heat exchanger 11 has a first side 11a and a second side 11b on either side of F1. The fan 12 is located on the first side 11a and downstream of the heat exchanger 11. That is, the heat exchanger 11 and the fan 12 are arranged sequentially along the airflow direction, meaning the airflow first passes through the heat exchanger 11 and then through the fan 12. The suction generated by the fan 12 promotes sufficient contact and heat exchange between the outdoor air and the heat exchanger 11, thereby improving heat exchange efficiency.

[0055] For example, the first direction F1 is the front-to-back direction, the first side 11a is the front side of the heat exchanger 11, the second side 11b is the rear side of the heat exchanger 11, the outdoor unit 1 has a casing, an air outlet shroud 17 is provided on the front side of the casing, the heat exchanger 11 is a U-shaped heat exchanger with the middle rear and both ends facing forward, so that a receiving space is formed between the front side of the casing and the U-shaped heat exchanger, and the fan 12 is arranged between the heat exchanger 11 and the air outlet shroud 17 and is located in this receiving space. Thus, by setting the U-shaped heat exchanger, the heat exchange area of ​​the heat exchanger 11 is increased, and by placing the fan 12 in the receiving space, the internal space of the outdoor unit 1 is fully utilized, which helps to reduce the overall volume of the outdoor unit 1, making the structure of the window air conditioner 100 more compact, and improving the applicability and installation convenience of the window air conditioner 100.

[0056] refer to Figure 2 and Figure 3The window air conditioner 100 includes a fan mounting bracket 3. A portion of the fan mounting bracket 3 is located on a first side 11a and is used to mount a fan 12. That is, the fan 12 is mounted on the portion of the fan mounting bracket 3 located on the first side 11a of the heat exchanger 11. The upper and lower ends of the fan mounting bracket 3 are fixed respectively. The upper end of the fan mounting bracket 3 is fixed at an extension 321 of the fan mounting bracket 3. The extension 321 includes a first extension 3211 extending to the second side 11b and / or a second extension 3212 extending above the fan 12.

[0057] The phrase "the upper and lower ends of the fan mounting bracket 3 are fixed" means that the lower end of the fan mounting bracket 3 is connected to certain components in the window air conditioner 100 (such as the outer chassis 2, or the mounting boss installed on the outer chassis 2) and is fixed and limited, preventing free movement; the upper end of the fan mounting bracket 3 is connected to certain components in the window air conditioner 100 (such as the electrical control component 13, the anti-collision strip 15, or the outer casing of the outdoor unit 1, etc.) and is fixed and limited, preventing free movement.

[0058] The phrase "the upper end of the fan mounting bracket 3 is fixed at a position on the extension 321 of the fan mounting bracket 3, the extension 321 including a first extension 3211 extending to the second side 11b and / or a second extension 3212 extending above the fan 12" means that the upper end of the fan mounting bracket 3 has at least one of the first extension 3211 and the second extension 3212, the upper end of the fan mounting bracket 3 can be fixed by the first extension 3211, and the upper end of the fan mounting bracket 3 can also be fixed by the second extension 3212.

[0059] The location of the fixing point on the first extension 3211 is not limited, and the number of fixing points on the first extension 3211 is not limited; it can be one or more. Similarly, the location of the fixing point on the second extension 3212 is not limited, and the number of fixing points on the second extension 3212 is not limited; it can be one or more.

[0060] Therefore, the first extension 3211 and / or the second extension 3212 used to fix the upper end of the fan mounting bracket 3 make full use of the space inside the outdoor unit 1, improve the fixing reliability of the upper end of the fan mounting bracket 3, and construct a multi-directional connection and a stable support system by fixing the upper and lower ends of the fan mounting bracket 3 respectively. This enhances the deformation resistance of the entire fan mounting bracket 3, the installation stability and support strength of the entire fan mounting bracket 3, and thus improves the reliability and stability of the fan 12 installed on the fan mounting bracket 3. The multi-directional connection can effectively disperse the vibration and stress generated during the operation of the fan 12, reduce the shaking and noise of the fan 12, and reduce the risk of collision between the fan 12 and surrounding components in extreme or special circumstances (such as transportation or drop tests), thereby improving the reliability of the window air conditioner 100.

[0061] In the technical solution of this application, the upper and lower ends of the fan mounting bracket 3 are fixed respectively. The upper end of the fan mounting bracket 3 is fixed at the position on the extension 321 of the fan mounting bracket 3. The extension 321 includes a first extension 3211 extending to the second side 11b and / or a second extension 3212 extending to the top of the fan 12. This provides a multi-connection point support structure for the fan mounting bracket 3, enhances the deformation resistance of the entire fan mounting bracket 3, and improves the structural stability of the window air conditioner 100 during long-term use. Compared with the method in related technologies where only the lower end of the fan mounting bracket is fixed and the upper end is free, this increases the connection points of the fan mounting bracket 3, improves the stability of the fan 12 during operation, reduces the shaking caused by vibration, reduces the risk of the fan 12 colliding with surrounding components under special circumstances, and improves the reliability and stability of the window air conditioner 100.

[0062] In some embodiments, the upper end of the fan mounting bracket 3 is fixed at both ends in a first direction F1. Exemplarily, the first direction F1 is the front-to-back direction, and the front and back ends of the upper end of the fan mounting bracket 3 are fixed respectively. This facilitates installation and fixation, and makes the installation of the fan mounting bracket 3 more stable and reliable. It is worth noting that the first direction F1 is not limited to the front-to-back direction; for example, it could also be the left-to-right direction, etc. Furthermore, it is understood that for the window air conditioner 100, the outdoor unit 1 and the indoor unit 4 are arranged in a front-to-back direction.

[0063] Of course, this application is not limited to this. For example, the upper end of the fan mounting bracket 3 can also be fixed in the middle of the first extension 3211 or other positions, and the upper end of the fan mounting bracket 3 can also be fixed in the middle of the second extension 3212 or other positions, thereby achieving flexible design.

[0064] refer to Figures 2-5In some embodiments, the fan mounting bracket 3 includes a mounting bracket 31 and a connecting plate 32. The mounting bracket 31 includes a vertical frame portion 311, which is located between the fan 12 and the heat exchanger 11, and the fan 12 is mounted on the vertical frame portion 311. The connecting plate 32 spans above the heat exchanger 11. A portion of the connecting plate 32 is located on a first side 11a and is assembled and connected to the mounting bracket 31. A portion of the connecting plate 32 is located on a second side 11b to form a first extension portion 3211.

[0065] In the above technical solution, the fan mounting bracket 3 is divided into two parts: a mounting bracket 31 and a connecting plate 32, making the structure of each component relatively simple. The mounting bracket 31 primarily supports the fan 12, and its shape and size can be specifically designed according to the fan's specifications, without needing to consider compatibility with the complex structure above the heat exchanger 11. The connecting plate 32 mainly serves to span above the heat exchanger 11 for fixation and assembly connection with the mounting bracket 31. Its shape can also be optimized according to the space above the heat exchanger and assembly requirements. Compared to the integrated fan mounting bracket, the processing of the connecting plate 32 does not require consideration of supporting the fan 12, thus facilitating processing and improving the compatibility between the connecting plate 32 and the heat exchanger 11.

[0066] For example, during the assembly process, since the fan mounting bracket 3 is divided into two parts, the fan 12 can be installed onto the mounting bracket 31 first, and then the connecting plate 32 can be placed across the heat exchanger 11 and assembled and connected to the mounting bracket 31 with the fan 12 already installed. This step-by-step assembly makes the assembly more convenient. At the same time, step-by-step assembly also helps to improve the assembly accuracy and ensure the stability and reliability of the overall structure of the fan mounting bracket 3. In addition, the fan mounting bracket 3 is divided into two parts, the mounting bracket 31 and the connecting plate 32, which also facilitates the maintenance or replacement of the fan 12, shortens the maintenance time, and reduces the maintenance cost. Of course, the mounting bracket 31 and the connecting plate 32 can be assembled first, and then the fan 12 can be installed onto the mounting bracket 31, and then installed onto the heat exchanger 11; or, the mounting bracket 31 and the connecting plate 32 can be assembled first, and then installed onto the heat exchanger 11, and then the fan 12 can be installed onto the mounting bracket 31. Multiple methods can be flexibly selected.

[0067] In the embodiments of this application, the shape of the mounting bracket 31 is not limited. For example, the mounting bracket 31 can be a frame-type mounting bracket, which is made of metal pipes or profiles welded or assembled into a frame structure. The frame can be reinforced with ribs as needed to further improve its load-bearing capacity. For example, the mounting bracket 31 can be a plate-type mounting bracket, which is made of metal plates by stamping or cutting. The mounting holes and ribs on the plate are provided to meet the installation requirements of the fan. Of course, it can also be other shapes and materials.

[0068] In the embodiments of this application, the assembly and connection method of the connecting plate 32 and the mounting bracket 31 is not limited. For example, it can be bolt connection, snap connection, welding, etc.

[0069] refer to Figures 2-5 In some embodiments, the mounting bracket 31 further includes an upper frame portion 312, which is located at the upper end of the vertical frame portion 311 and extends above the fan 12 to define a second extension portion 3212. The second extension portion 3212 extends above the fan 12, providing the mounting bracket 31 with more installation options and adjustment space. Exemplarily, in different installation environments and air conditioner models, the connection method and position of the second extension portion 3212 with surrounding components can be adjusted according to the actual situation.

[0070] For example, the second extension 3212 can be connected to the air outlet shroud 17 to increase the structural strength of the mounting bracket 31; for another example, the second extension 3212 can be connected to the top plate of the outer casing to increase the structural strength of the mounting bracket 31; for yet another example, the second extension 3212 can be connected to the side panel of the outer casing to increase the structural strength of the mounting bracket 31.

[0071] refer to Figures 2-5 In some embodiments, the connecting plate 32 includes an overlapping portion 322, and the mounting bracket 31 also includes an upper frame portion 312, which is located at the upper end of the vertical frame portion 311, and the overlapping portion 322 overlaps the top of the upper frame portion 312; the overlapping portion 322 and the upper frame portion 312 are positioned and engaged by a positioning structure 33, which includes a vertically extending insert 3221 and an insertion hole 3121 that engages with the insert 3221.

[0072] For example, the overlapping portion 322 is provided with a vertically downward extending insert 3221, and the top of the upper frame portion 312 is provided with an insertion hole 3121 that mates with the insert 3221. Alternatively, the top of the upper frame portion 312 may be provided with a vertically upward extending insert 3221, and the overlapping portion 322 may be provided with an insertion hole 3121 that mates with the insert 3221.

[0073] In the above technical solution, the positioning structure 33 uses a vertically extending insert 3221 that engages with the socket 3121, enabling the connecting plate 32 and the mounting bracket 31 to be quickly positioned and overlapped. During assembly, the installer only needs to align the insert 3221 with the socket 3121 and insert it to quickly position and install the connecting plate 32 into the predetermined position of the mounting bracket 31, improving assembly efficiency. When maintenance or repair of the air conditioner is required, and the connecting plate 32 and the mounting bracket 31 need to be separated, the insert 3221 can be easily pulled out of the socket 3121 to separate the connecting plate 32 from the mounting bracket 31.

[0074] The engagement of the insert 3221 and the socket 3121 not only serves a positioning function but also limits the relative movement between the connecting plate 32 and the mounting bracket 31 to a certain extent. During the operation of the air conditioner, the fan 12 will vibrate, and the positioning structure 33 can effectively resist these external forces, reducing the possibility of misalignment or separation between the connecting plate 32 and the mounting bracket 31, thereby ensuring the structural stability of the entire fan mounting frame 3.

[0075] refer to Figures 2-5 In some embodiments, the connecting plate 32 includes an overlapping portion 322, and the mounting bracket 31 also includes an upper frame portion 312, which is located at the upper end of the vertical frame portion 311, and the overlapping portion 322 overlaps the top of the upper frame portion 312; the overlapping portion 322 and the upper frame portion 312 are fixedly connected by threaded fasteners 34.

[0076] In the above technical solution, the overlapping portion 322 of the connecting plate 32 overlaps the top of the upper frame portion 312 of the mounting bracket 31 and is fixedly connected by threaded fasteners 34, thereby forming a stable mechanical connection structure. This prevents loosening, separation, or relative displacement between the connecting plate 32 and the mounting bracket 31, thus ensuring the structural stability of the entire wind turbine mounting frame 3. The overlapping design of the overlapping portion 322 and the upper frame portion 312 increases the connection area. Combined with the fixing of the threaded fasteners 34, this allows the connecting plate 32 and the mounting bracket 31 to better share the weight of the wind turbine 12 and the dynamic load generated during operation. This avoids local stress concentration and thus improves the load-bearing capacity of the entire wind turbine mounting frame 3.

[0077] refer to Figure 2 and Figure 3 In some embodiments, the connecting plate 32 includes an overlapping portion 322, and the mounting bracket 31 also includes an upper frame portion 312, which is located at the upper end of the vertical frame portion 311, with the overlapping portion 322 overlapping the top of the upper frame portion 312; wherein, the overlapping portion 322 and the upper frame portion 312 are positioned and engaged by a positioning structure 33, which includes a vertically extending insert 3221 and an insertion hole 3121 that engages with the insert 3221; and the overlapping portion 322 and the upper frame portion 312 are fixedly connected by a threaded fastener 34.

[0078] Therefore, during the assembly and connection of the connecting plate 32 and the mounting bracket 31, the positioning and cooperation of the insert 3221 and the insertion hole 3121 can be used first to restrict the movement of the connecting plate 32 and the mounting bracket 31 in the first direction F1, thereby determining the relative position of the overlapping part 322 of the connecting plate 32 and the upper part 312 of the mounting bracket 31, and realizing the initial assembly and connection of the connecting plate 32 and the mounting bracket 31. Then, the positioned parts are firmly fixed by the threaded fasteners 34, which can improve the assembly efficiency and make the connecting plate 32 and the mounting bracket 31 form a stable whole, preventing the positioning deviation caused by vibration and other factors during subsequent use or transportation, reducing the probability of loose connection, breakage and other failures, and ensuring the stability of the wind turbine mounting bracket 3 structure.

[0079] In some embodiments, reference Figures 3-5 The connecting plate 32 includes a flange portion 323, which is located at both ends of the overlap portion 322 in the second direction F2. The flange portion 323 extends downward from the overlap portion 322, and the flange portions 323 on both sides stop on both sides of the upper frame portion 312 in the second direction F2. The second direction F2 is horizontal and perpendicular to the first direction F1.

[0080] In the above technical solution, the flanged portion 323 is located at both ends of the overlap portion 322 in the second direction F2 and extends downwards. The flanged portions 323 on both sides stop on both sides of the upper frame portion 312. Thus, during installation, the flanged portion 323 can play a role in limiting and positioning in the second direction F2. Combined with the positioning function of the vertical insert 3221 and the insertion hole 3121 in the first direction F1 in the previous embodiment, the assembly and connection positioning of the connecting plate 32 and the mounting bracket 31 can be more accurate, making it easier for the overlap portion 322 and the upper frame portion 312 to be fixedly connected by the threaded fastener 34, thereby improving the assembly and connection efficiency. At the same time, the all-round horizontal limiting can also improve the wind resistance of the fan mounting bracket 3. In strong wind weather, the fan and the mounting bracket will be subjected to a large horizontal wind force. The flanged portion 323 can prevent the connecting plate 32 from sliding horizontally on the upper frame portion 312, ensuring that the fan always stays in the correct installation position, and ensuring the normal operation and safety of the fan.

[0081] Furthermore, the flanged portion 323 and the overlapping portion 322 form a groove-like structure that encloses the upper frame portion 312, increasing the contact area between the connecting plate 32 and the mounting bracket 31, resulting in a tighter connection. When bearing the weight of the wind turbine and the dynamic loads during operation, the larger contact area can disperse stress, reduce local stress concentration, and thus improve the strength and durability of the connecting portion 321.

[0082] In the above technical solution, the flange 323 increases the structural strength and rigidity of the connecting plate 32. For the mounting bracket 31, the stopping effect of the flange 323 also enhances the stability of the mounting bracket 31. Because the connecting plate 32 is closely connected to the mounting bracket 31, the strengthening of the connecting plate 32 structure helps to distribute the load more evenly to the mounting bracket 31, reducing the situation of excessive local stress on the mounting bracket 31 and extending the service life of the entire wind turbine mounting bracket 3.

[0083] refer to Figure 1 and Figure 2 In some embodiments, the fan mounting bracket 3 includes a support portion 325 and a limiting portion 324. The support portion 325 is disposed on the top of the heat exchanger 11, and the limiting portion 324 extends downward from the support portion 325 and includes a first limiting portion 3241 and a second limiting portion 3242. The first limiting portion 3241 and the second limiting portion 3242 stop on the first side 11a and the second side 11b of the heat exchanger 11, respectively. That is, the first limiting portion 3241 and the second limiting portion 3242 stop on both sides of the heat exchanger 11 along the first direction F1.

[0084] In the above technical solution, the first limiting part 3241 and the second limiting part 3242 stop on both sides of the heat exchanger 11 along the first direction F1, so that the fan 12 and the heat exchanger 11 are relatively fixed, thereby maintaining the distance between the fan 12 and the heat exchanger 11 and reducing the possibility of collision between the fan 12 and the heat exchanger 11.

[0085] For example, when the fan mounting bracket 3 includes a connecting plate 32, the connecting plate 32 may include a support portion 325 and a limiting portion 324. The support portion 325 of the connecting plate 32 is located on the top of the heat exchanger 11. The support portion 325 and the heat exchanger 11 can be in contact or in clearance fit. When in contact, the heat exchanger 11 can provide a certain support for the connecting plate 32, thereby improving the positional stability of the connecting plate 32.

[0086] In the embodiments of this application, the shape of the support portion 325 is not limited; for example, such as Figure 4 As shown, the support part 325 can be in the shape of a flat plate, which is simple and easy to process and can provide a large support area. It can evenly distribute the weight of the connecting plate 32 on the top of the heat exchanger 11, preventing damage to the fins of the heat exchanger 11. The limiting part 324 can be formed by bending the support part 325 downwards, which is convenient for processing and manufacturing and has a more reliable structural strength.

[0087] refer to Figures 1-2The window air conditioner 100 also includes an outer chassis 2. The outdoor unit 1 and the fan mounting bracket 3 are both mounted on the outer chassis 2. The lower end of the fan mounting bracket 3 is directly or indirectly connected to the outer chassis 2 for fixation, and the extension 321 is indirectly connected to the outer chassis 2 for fixation. That is, the extension 321 is indirectly connected to the outer chassis 2 through a component 21, which can be a component directly or indirectly mounted on the outer chassis 2. Therefore, both the lower and upper ends of the fan mounting bracket 3 can be relatively fixed to the outer chassis 2, thereby improving the ease of fixing the fan mounting bracket 3, and the outer chassis 2 can provide reliable support and limiting for the fan mounting bracket 3.

[0088] For example, in this embodiment, welding, bolting, riveting, etc., can be used. For instance, bolts can be used to directly fix the bottom of the fan mounting bracket 3 to the reserved holes on the outer chassis 2. This connection method is simple and direct, and has high connection strength and stability. Another example is that a mounting boss is first installed on the outer chassis 2, and then the bottom of the fan mounting bracket 3 is supported and connected to the mounting boss. This provides more flexible installation and adjustment space. For example, if a heating element is also provided on the outer chassis 2, the connection position between the fan mounting bracket 3 and the outer chassis 2 can be adjusted by adjusting the mounting boss, thereby achieving a setting where the fan mounting bracket 3 avoids the heating element.

[0089] refer to Figure 3 and Figure 4 In some embodiments, the outdoor unit 1 includes an electronic control component 13, which is located on the second side 11b, that is, on the side of the heat exchanger 11 away from the fan 12 in the first direction F1. The electronic control component 13 is mounted on the outer chassis 2, that is, directly or indirectly connected to the outer chassis 2. The first extension 3211 is connected to the electronic control component 13 so that the first extension 3211 is fixed.

[0090] In the above technical solution, the electronic control component 13 is directly or indirectly connected to the outer chassis 2, and the first extension 3211 is connected to the electronic control component 13, thereby obtaining indirect fixed support for the outer chassis 2 through the electronic control component 13. The outer chassis 2, as the structural foundation of the outdoor unit 1, has high strength and stability. The first extension 3211 indirectly obtains support for the outer chassis 2 through the electronic control component 13, which can enhance the structural strength of the fan mounting frame 3, increase the number of fixed connection points for the fan mounting frame 3, and thus reduce the possibility of deformation and damage to the fan mounting frame 3.

[0091] Furthermore, the connection between the first extension 3211 and the electrical control component 13 forms an interconnected whole among the various components of the outdoor unit 1, thereby improving the overall resistance to deformation during transportation, installation, and use. During transportation, the outdoor unit 1 may be subjected to bumps and collisions; the tight connection between the various components can reduce damage caused by relative movement. During installation and use, the integrated structure can better adapt to changes in the external environment, such as thermal expansion and contraction caused by temperature changes, ensuring the normal operation of the outdoor unit 1.

[0092] Furthermore, during operation, the motor in the fan 12 may generate electromagnetic radiation. If the electronic control component 13 is too close to the fan, this electromagnetic radiation may interfere with the normal operation of the electronic components in the electronic control component 13, leading to problems such as control signal distortion and malfunction. By placing the electronic control component 13 on the side of the heat exchanger 11 away from the fan 12 in the first direction F1, the impact of the motor's electromagnetic radiation on the electronic control component 13 can be reduced, thereby improving the operational reliability of the window air conditioner 100.

[0093] refer to Figure 3 and Figure 4 In some embodiments, the outdoor unit 1 includes a compressor component 14 and a crash barrier 15. The compressor component 14 is located on the second side 11b, that is, on the side of the heat exchanger 11 away from the fan 12 in the first direction F1. The crash barrier 15 is also located on the second side 11b, that is, on the side of the heat exchanger 11 away from the fan 12 in the first direction F1, and is situated on the side of the compressor component 14 away from the heat exchanger 11. Thus, the crash barrier 15 provides reliable impact protection for the compressor component 14. During the transportation, installation, and use of the outdoor unit 1, it may be subjected to collisions with external objects. For example, when the window air conditioner 100 is dropped during transportation, the crash barrier 15 first absorbs the impact force, absorbing and dispersing energy through its own deformation, reducing the impact force transmitted to the compressor component 14, thereby reducing the risk of damage to the compressor component 14 and improving the structural stability of the entire outdoor unit 1.

[0094] refer to Figure 3 and Figure 4 In some embodiments, the anti-collision strip 15 is installed on the outer chassis 2, that is, the anti-collision strip 15 is directly or indirectly connected to the outer chassis 2, and the first extension 3211 is connected to the anti-collision strip 15 so that the first extension 3211 is fixed.

[0095] In the above technical solution, the anti-collision strip 15 is directly or indirectly connected to the outer chassis 2, and the first extension 3211 is connected to the anti-collision strip 15, thereby obtaining fixed support for the outer chassis 2 through the anti-collision strip 15. The outer chassis 2, as the structural foundation of the outdoor unit 1, has high strength and stability. The first extension 3211 indirectly obtains fixed support for the outer chassis 2 through the anti-collision strip 15, which can enhance the structural strength of the fan mounting frame 3, increase the number of fixed connection points of the fan mounting frame 3, and thus reduce the possibility of deformation and damage to the fan mounting frame 3.

[0096] Furthermore, during the operation of the window air conditioner 100, components such as the compressor 141 will vibrate. When the vibration passes through the anti-collision strip 15, due to the damping characteristics of the anti-collision strip 15 material, some of the vibration energy will be absorbed and dissipated, reducing the transmission of vibration to the first extension 3211 and other related components, and improving the stability of the fan mounting bracket 3.

[0097] Understandably, the first extension 3211 can be connected to both the electronic control component 13 and the anti-collision strip 15 simultaneously to achieve multiple fixation. Furthermore, it is worth noting that, in addition to connecting to the electronic control component 13 and the anti-collision strip 15 to receive support from the outer chassis 2, the first extension 3211 can also be provided with other support structures. These other support structures can exist independently or in combination with at least one of the electronic control component 13 and the anti-collision strip 15, designed according to the shape and stress conditions of the first extension 3211 to achieve better support.

[0098] refer to Figure 6 and Figure 7 In some embodiments, the compressor component 14 includes a compressor 141 and a liquid receiver 142 rigidly connected together. The liquid receiver 142 and the compressor 141 are arranged along a second direction F2, which is horizontal and perpendicular to the first direction F1. The outdoor unit 1 also includes an outer casing 16, which is disposed on the side of the compressor component 14 away from the heat exchanger 11 in the first direction F1. The distance from the liquid receiver 142 to the outer casing 16 is greater than the distance from the compressor 141 to the outer casing 16. A crash barrier 15 is disposed between the liquid receiver 142 and the outer casing 16.

[0099] The specific orientation of the outer casing 16 is determined according to the position of the compressor 14. For example, if the compressor 14 is located behind the heat exchanger 11, then the outer casing 16 is located behind the compressor 14. For example, if the compressor 14 is located to the left of the heat exchanger 11, then the outer casing 16 is located to the left of the compressor 14, and so on.

[0100] In the above technical solution, the arrangement of the compressor 141 and the liquid receiver 142 improves the structural compactness. The anti-collision strip 15 is placed between the liquid receiver 142 and the outer casing 16, and the compressor 141 and the liquid receiver 142 are rigidly connected, reducing the direct impact between the outer casing 16 and the compressor component 14, and improving the structural safety of the outdoor air conditioning unit 1 during transportation, installation, and use. The distance from the liquid receiver 142 to the outer casing 16 is greater than the distance from the compressor 141 to the outer casing 16. The anti-collision strip 15 is placed between the liquid receiver 142 and the outer casing 16, and the compressor 141 and the liquid receiver 142 are rigidly connected, allowing the anti-collision strip 15 to make more full use of space and achieve a protective effect in a compact environment.

[0101] refer to Figure 5 and Figure 6 In some embodiments, the outdoor unit 1 includes an air outlet shroud 17, which is located downstream of the fan 12 along the airflow direction. The air outlet shroud 17 is disposed on the side of the fan 12 away from the heat exchanger 11 in the first direction F1, and the air outlet shroud 17 is directly or indirectly connected to the outer chassis 2. The second extension 3212 has a vertically extending connecting portion 32121 at one end in the first direction F1 away from the heat exchanger 11. The connecting portion 32121 is connected to the air outlet shroud 17 to fix the second extension 3212.

[0102] In the above technical solution, the second extension 3212 indirectly obtains the fixed support of the outer chassis 2 through the air outlet cover 17, which can enhance the structural strength of the fan mounting frame 3 and increase the fixed connection points of the fan mounting frame 3, thereby reducing the possibility of deformation and damage to the fan mounting frame 3. In addition, the connection between the second extension 3212 and the air outlet cover 17 makes the various components of the outdoor unit 1 form an interconnected whole, thereby improving the deformation resistance of the entire outdoor unit 1 during transportation, installation and use.

[0103] In the embodiments of this application, the extension 321 is indirectly connected to the outer chassis 2 via a component 21 (such as the aforementioned electronic control component 13, anti-collision strip 15, etc.) to fix the extension 321. That is, the extension 321 is rigidly connected to the component 21, and the component 21 is directly or indirectly rigidly connected to the outer chassis 2. Here, "rigid connection" is interpreted broadly. If vibration damping material is provided at the connection between the extension 321 and the component 21, or at the connection between the component 21 and the outer chassis 2, so that the degree of connection is close to a rigid connection, it can also be regarded as a rigid connection.

[0104] Component 21 is directly and rigidly connected to the outer chassis 2, providing high-strength support for the extension 321 and the entire wind turbine mounting frame 3. The outer chassis 2, as the basic support component 325 of the outdoor unit 1, ensures that component 21 will not undergo significant deformation or displacement when subjected to the force transmitted by the extension 321, thus guaranteeing the stability and reliability of the entire structure. Furthermore, direct connection methods typically result in a simpler structure and easier installation. During unit assembly, component 21 can be directly connected to the outer chassis 2 using bolts, welding, or other methods, reducing intermediate steps and additional connection parts 321, improving installation efficiency, and lowering installation costs.

[0105] In this system, component 21 is indirectly rigidly connected to the outer chassis 2. For example, this indirect rigid connection is achieved through intermediate components. This connection can be adjusted and optimized according to the actual installation environment and design requirements, offering a degree of adaptability and flexibility. Furthermore, some intermediate components may possess shock absorption and buffering capabilities, absorbing and dispersing vibrations and impacts transmitted from component 21 to the outer chassis 2 to a certain extent. This helps reduce the impact of vibration on the outer chassis 2, lowers noise during unit operation, and improves equipment comfort and service life.

[0106] In some embodiments, component 21 is a metal part. This gives component 21 high strength. Metal materials can withstand large external forces, are not easily deformed or damaged, and can ensure the reliability of the rigid connection, thereby providing reliable support for the extension 321. Of course, this application is not limited to this, and component 21 can also be made of other materials with high structural strength.

[0107] refer to Figure 5 In some embodiments, the extension 321 is rigidly connected to the component 21, and the component 21 is directly or indirectly rigidly connected to the outer chassis 2, and the component 21 is a metal part. Thus, the component 21 provides good support and fixation for the extension 321, forming a high-strength and stable support and fixing structure. Therefore, the fan mounting bracket 3 can effectively support the fan 12, thereby suppressing fan sway, reducing the risk of collision between the fan 12 and surrounding components, and improving the overall reliability of the air conditioner operation.

[0108] refer to Figure 4 and Figure 7 In some embodiments, the fan mounting bracket 3 has a wire harness structure 326 for restraining the wiring harnesses. During the installation and operation of equipment such as air conditioners, numerous wiring harnesses are involved, including power lines and control lines. Without a dedicated restraint structure, the wiring harnesses are easily tangled. The wire harness structure 326 can fix the wiring harnesses according to certain rules and order, making the wiring harnesses neatly arranged, greatly improving the orderliness of wiring harness management, and facilitating subsequent installation, commissioning, and maintenance.

[0109] For example, when assembling outdoor unit 1, installers can quickly organize and secure the wiring harnesses in the wiring harness structure 326, improving installation efficiency. Furthermore, during later maintenance, when it is necessary to inspect or replace the wiring harnesses, the neat wiring harness layout makes it easier for maintenance personnel to locate the target harness, reducing search time and lowering maintenance difficulty.

[0110] If the tangled wire harness comes into contact with metal parts or other live conductors inside the outdoor unit 1, it may cause a short circuit. The wire harness structure 326 fixes the wire harness within a certain range, reducing the chance of accidental contact between the wire harness and surrounding components, thereby reducing the risk of short circuit and ensuring the safe operation of the outdoor unit 1.

[0111] Outdoor unit 1 will vibrate during operation and may be subject to collisions with external objects. Without the wiring harness structure 326, the wiring harness is easily damaged by vibration and collisions, such as breakage or insulation damage. The wiring harness structure 326 can fix the wiring harness in a relatively stable position, reduce the shaking and displacement of the wiring harness, thereby avoiding damage to the wiring harness caused by mechanical action and improving the reliability of the window air conditioner 100.

[0112] refer to Figure 4 and Figure 7 In some embodiments, the wire harness structure 326 includes a flap 3261 and / or a wire channel 3262.

[0113] The folding tab 3261 can wrap or fix the wire harness inside or to one side through a folding action. For example, after folding the folding tab 3261 along the preset crease, a relatively closed wiring space can be formed, confining the wire harness within this wiring space and preventing the wire harness from swinging or scattering around the fan mounting bracket 3. In addition, the folding tab 3261 can provide a physical barrier for the wire harness, reducing direct damage to the wire harness from external factors.

[0114] The cable tray 3262 guides the wire harness along a predetermined path. This ensures the wire harness is neatly arranged on the fan mounting bracket 3, reducing crossings and tangles. The edges of the cable tray 3262 also provide some restraint to the wire harness, preventing displacement due to vibrations generated during fan operation.

[0115] refer to Figure 4 and Figure 7 In some embodiments, the wiring harness of the fan 12 is constrained by the wiring harness structure 326. The fan 12 involves power transmission and signal interaction during operation, therefore multiple wiring harnesses need to be connected to the fan 12. Constraining the wiring harnesses by the wiring harness structure 326 allows the wiring harnesses to be arranged according to a predetermined path and manner, making the internal layout of the entire outdoor unit 1 more orderly and organized.

[0116] refer to Figure 4 and Figure 7 In some embodiments, the wiring harness structure 326 includes a flap 3261 and / or a cable tray 3262; and the wiring harness of the fan 12 is constrained by the wiring harness structure 326. Thus, by employing the wiring harness structure 326, such as the flap 3261 and / or the cable tray 3262, various wiring harnesses of the fan 12 can be constrained, preventing the wiring harnesses from swinging or scattering around the fan mounting bracket 3, and reducing the crossing and tangling of the wiring harnesses. This arranges the wiring harnesses according to a predetermined path and method, making the internal layout of the entire outdoor unit 1 more orderly and organized.

[0117] refer to Figure 4 and Figure 7 In some embodiments, the outdoor unit 1 includes an electronic control component 13 and a compressor component 14, both of which are located on the side of the heat exchanger 11 away from the fan 12 in a first direction F1. The electronic control component 13 and the compressor component 14 are arranged along a second direction F2, which is horizontal and perpendicular to the first direction F1. A first extension 3211 is located between the electronic control component 13 and the compressor component 14 in the second direction F2. The wiring harness of the fan 12 is constrained by a wiring harness structure 326, and the wiring harness of the compressor component 14 is constrained by the wiring harness structure 326 and connected to the electronic control component 13.

[0118] For example, a vertical plate is provided on the side of the first extension 3211 near the compressor component 14, and a third wire passage 32613 is provided on the vertical plate, which runs through the second direction F2. A second wire passage 32612 runs vertically through the middle of the first extension 3211, and a first wire passage 32611 runs vertically through the edge of the support 325. The power cord of the fan 12 comes out from the lower part of the motor of the fan 12, turns upward and runs upward along the motor mounting bracket 3 to the support 325, and then gets into the first wire passage 32611. It extends through the top of the connecting plate 32 to the middle of the first extension 3211 and gets into the second wire passage 32612, and then enters the electrical control component 13. The compressor component 14 comes out from the top of the compressor 141, extends along the second direction F2, passes through the third wire passage 32613, and then gets into the second wire passage 32612 in the middle of the first extension 3211, and then enters the electrical control component 13.

[0119] In the above technical solution, the first extension 3211 is located between the electrical control component 13 and the compressor component 14 in the second direction F2, facilitating the arrangement of the wiring harnesses of the compressor component 14 and the fan 12. Specifically, the wiring harnesses of both the fan 12 and the compressor component 14 can be connected to the electrical control component 13 via reasonable paths, resulting in shorter wiring harness arrangement paths and reduced wiring harness length and bending. For example, the wiring harness of the compressor component 14 can be directly connected to the electrical control component 13 after being constrained by the wiring harness structure 326, avoiding wiring harness detours and tangles. This not only makes the wiring neater and more aesthetically pleasing but also reduces wiring harness resistance and signal interference, improving the stability and reliability of the electrical system. Furthermore, the wiring harness of the fan 12, constrained by the wiring harness structure 326, can be neatly arranged, reducing friction and collision between the wiring harness and surrounding components, lowering the risk of damage to the wiring harness insulation layer, thereby preventing electrical faults such as short circuits and leakage, and ensuring the electrical safety of the equipment.

[0120] refer to Figures 6-8 In some embodiments, the heat exchanger 11 is plate-shaped (e.g., a flat plate or a curved plate), and the first direction F1 is the thickness direction of the heat exchanger 11. Therefore, the fan 12 is arranged on the heat exchanger 11 along its thickness direction, allowing for a more compact installation in the outdoor unit 1 and effectively saving space. Simultaneously, it ensures a relatively short and uniform airflow path through the heat exchanger 11, reducing turbulence and resistance within the heat exchanger and improving airflow efficiency.

[0121] refer to Figures 6-8 In some embodiments, the fan 12 includes an axial flow impeller 121, which is mounted on the motor of the fan 12. The motor of the fan 12 is mounted on the motor mounting bracket 3. The first direction F1 is the axial direction of the axial flow impeller 121. Therefore, when the blades of the axial flow impeller 121 rotate, they push air to flow linearly along the axial direction, resulting in a larger volume of air passing through the impeller per unit time, meeting the heat exchange requirements of the outdoor unit 1 for a large amount of air. Furthermore, the axial flow fan can generate a certain wind pressure in the axial direction, which can overcome the resistance of the heat exchanger 11, allowing air to flow smoothly through the heat exchanger 11 and achieving effective heat exchange.

[0122] refer to Figures 6-8In some embodiments, the heat exchanger 11 is plate-shaped, and the first direction F1 is the thickness direction of the heat exchanger 11; the fan 12 includes an axial flow impeller 121, and the first direction F1 is the axial direction of the axial flow impeller 121. Thus, the fan 12 is arranged on the heat exchanger 11 along the thickness direction of the heat exchanger 11, allowing for more compact installation in the outdoor unit 1 and effectively saving space; at the same time, it makes the airflow path relatively short and uniform when passing through the heat exchanger, reducing airflow turbulence and resistance inside the heat exchanger, which is beneficial to improving airflow efficiency; when the blades of the axial flow impeller 121 rotate, they push the air to flow in a straight line along the axial direction, resulting in a larger volume of air passing through the impeller per unit time, meeting the heat exchange needs of the outdoor unit 1 for a large amount of air.

[0123] refer to Figure 1 , Figures 6-8 In some embodiments, the window air conditioner 100 includes an indoor unit 4, with a first direction F1 being the arrangement direction of the indoor unit 4 and the outdoor unit 1, and a fan 12 located on the side of the heat exchanger 11 away from the indoor unit 4. Thus, the window air conditioner 100 has a compact layout and saves space.

[0124] In some embodiments, the window air conditioner 100 further includes an inner chassis 5, which may be separate from or integrated with the outer chassis 2. When the inner chassis 5 and outer chassis 2 are separate, it provides greater flexibility for the independent installation and layout of the indoor unit 4 and the outdoor unit 1. When the inner chassis 5 and outer chassis 2 are integrated, it simplifies the overall structure of the air conditioner, reduces the connection and assembly processes between components, and improves production efficiency. Simultaneously, the integrated design enhances the overall integrity and stability of the structure, reducing vibration problems caused by loose component connections.

[0125] In some embodiments, the indoor unit 4 is mounted on the inner chassis 5 and includes an indoor heat exchanger 41 and an indoor fan 42; the first direction F1 is the arrangement direction of the indoor unit 4 and the outdoor unit 1, and the fan 12 is located on the side of the heat exchanger 11 away from the indoor unit 4; combined with Figure 5 The outdoor unit 1 also includes an electrical control component 13 and / or a compressor component 14 located on the side of the heat exchanger 11 near the indoor unit 4, and / or the outdoor unit 1 also includes an air outlet shroud 17 located on the side of the fan 12 away from the indoor unit 4.

[0126] In the above technical solution, the fan 12 is located on the side of the heat exchanger 11 furthest from the indoor unit 4, which is conducive to forming good airflow organization. When the fan 12 is running, it can draw in air from one side of the heat exchanger 11, allowing the air to flow evenly across the surface of the heat exchanger and carry away the heat in the heat exchanger 11. Placing the electronic control component 13 and / or the compressor component 14 on the side of the heat exchanger 11 closer to the indoor unit 4 is beneficial for the heat dissipation of the electronic control component 13 and the compressor component 14. The electronic control component 13 and the compressor component 14 generate heat during operation. Placing them on the side closer to the indoor unit 4 can utilize the airflow caused by the negative pressure of the fan 12 to help dissipate heat. Providing an air outlet shroud 17 on the side of the fan 12 furthest from the indoor unit 4 can further improve the heat dissipation effect. The air outlet shroud 17 can guide the air discharged by the fan 12 to flow in a certain direction and speed, reducing the rapid diffusion and recirculation of air after discharge, and reducing the accumulation of hot air around the outdoor unit 1. At the same time, the air hood 17 can also play a certain role in rain and dust protection, protecting the fan 12 and other components from the influence of the external environment and extending the service life of the equipment.

[0127] Of course, the electrical control components 13, compressor components 14, and air outlet shroud 17 can also serve as fixed connection points for the fan mounting bracket 3. These components enhance the installation stability of the fan mounting bracket 3. At the same time, the interconnection of these components forms an interconnected whole among the various components of the outdoor unit 1, improving the structural strength of the outdoor unit 1 and enhancing the deformation resistance of the entire outdoor unit 1 during transportation, installation, and use.
