Technical Field

[0002] This disclosure relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0003] An air conditioner is a device used to regulate indoor air temperature, humidity, airflow speed, and air cleanliness. It is widely used in homes, offices, commercial spaces, and industrial environments. Its basic principle is to transfer heat through the circulation of refrigerant, utilizing the physical processes of evaporation (absorbing heat) and condensation (releasing heat), thereby achieving a cooling or heating effect. With technological advancements, air conditioners not only possess cooling and heating functions but also integrate dehumidification, air purification, and other functions, becoming an indispensable appliance in modern life.

[0004] Currently, the support structure of air conditioners is usually achieved by installing support components on the base, thereby providing stable support for portable air conditioners and ensuring their stability and safety in various usage environments. Summary of the Invention

[0005] This disclosure aims to solve the support problem of air conditioners.

[0006] This disclosure provides an air conditioner with several embodiments, including a housing configured as the outer shell of the air conditioner; a chassis disposed at the bottom of the housing; and multiple support legs disposed on the chassis. The opposite ends of the multiple support legs are sequentially joined end-to-end and continuously arranged circumferentially around the outer periphery of the chassis. The opposite ends of each support leg are a first end and a second end, respectively. The first end of each support leg has a locking groove, and the second end of each support leg has a positioning portion adapted to the locking groove. The positioning portion of the support leg can be aligned and inserted into the locking groove of an adjacent support leg, so that the second end of the support leg is joined to the first end of an adjacent support leg. The locking groove of each support leg can be aligned and inserted into the positioning portion of another adjacent support leg, so that the first end of the support leg is joined to the second end of another adjacent support leg.

[0007] The above technical solution involves inserting the positioning part of a support foot into the locking groove of an adjacent support foot, allowing the positioning part to engage within the groove, thereby splicing the second end of the support foot with the first end of the adjacent support foot. Similarly, by correspondingly engaging the locking groove of one support foot with the positioning part of another adjacent support foot, the first end of the support foot is spliced ​​with the second end of the other adjacent support foot. This method of splicing support feet without tools eliminates the need for tool installation, reducing installation difficulty, simplifying the chassis support structure, and lowering user operating complexity. Furthermore, the assembled support feet can form a wraparound support structure, ensuring even force distribution and effectively improving support strength. Moreover, the identical structure of each support foot allows for flexible splicing and combination. Attached Figure Description

[0052] The following description, in conjunction with the accompanying drawings, clearly and completely describes some embodiments of this disclosure. Obviously, the described embodiments are merely some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0053] In related air conditioners, multiple support feet are used to support the main unit in order to improve the support performance of the support feet. However, the connection structure between the support feet and the main unit is complicated, which makes the installation inconvenient and time-consuming for users. On the other hand, the support feet will affect the aesthetics of the main unit installation and reduce the user experience.

[0054] To address the aforementioned problems, as shown in Figure 1, some embodiments of this disclosure provide an air conditioner that may include a housing 1. The housing 1 may be configured as the outer casing of the air conditioner. The interior of the housing 1 may be used to provide installation space.

[0055] As shown in Figure 1, in some embodiments, the housing 1 can adopt a hollow cuboid structure. The length of the housing 1 can be arranged along the height direction, so that the air conditioner can be installed vertically in the usage site, increasing the height of the air conditioner and reducing the space occupied by the air conditioner.

[0056] It should be noted that in other embodiments, the external shape of the housing 1 can be designed as needed, and no limitation is made here.

[0057] As shown in Figure 2, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 can respectively function as a condenser and an evaporator, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby executing either a cooling cycle or a heating cycle for the air conditioner.

[0058] Specifically, in the refrigeration cycle, the outdoor heat exchanger 22 can act as a condenser, and the indoor heat exchanger 23 can act as an evaporator. In the heating cycle, the outdoor heat exchanger 22 can act as an evaporator, and the indoor heat exchanger 23 can act as a condenser.

[0059] It should be noted that both the refrigeration and heating cycles involve a series of processes, including compression, condensation, expansion, and evaporation, and the supply of refrigerant to the conditioned and heat-exchanged air.

[0060] Compressor 21 is used to compress refrigerant gas and discharge the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

[0061] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0062] The evaporator evaporates the expanded refrigerant and returns the refrigerant gas, now at a low temperature and low pressure, to the compressor 21. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the surrounding environment.

[0063] Throughout the cycle, the air conditioner can regulate the temperature of the indoor space, improve the comfort of the indoor space, and enhance the user experience.

[0064] As shown in Figure 2, in some embodiments, the air conditioner may include an outdoor fan assembly 3. The outdoor fan assembly 3 may be arranged opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 can be used to introduce outdoor air into the casing 1 for heat exchange with the outdoor heat exchanger 22, forming a heat exchange airflow.

[0065] For example, during the cooling cycle, the outdoor heat exchanger 22 acts as a condenser, and the outdoor fan assembly 3 can draw in outside air and blow it onto the outdoor heat exchanger 22 to dissipate heat and lower its temperature. During the heating cycle, the outdoor heat exchanger 22 acts as an evaporator, and the outdoor fan assembly 3 can draw in outside air and blow it onto the outdoor heat exchanger 22 to raise its temperature.

[0066] As shown in Figure 2, in some embodiments, the air conditioner may include an indoor fan assembly 4. The indoor fan assembly 4 may be arranged opposite to the indoor heat exchanger 23. The indoor fan assembly 4 can be used to introduce indoor air into the casing 1 for heat exchange with the indoor heat exchanger 23, forming a heat exchange airflow.

[0067] For example, during the refrigeration cycle, the indoor heat exchanger 23 acts as an evaporator, and the indoor fan assembly 4 can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger 23 to exchange heat with it, thereby reducing the temperature of the air flowing through the indoor heat exchanger 23 and blowing the cooled air back into the room to lower the indoor air temperature.

[0068] For example, during the heating cycle, the indoor heat exchanger 23 acts as a condenser, and the outdoor fan assembly 3 can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger 23 to exchange heat with it, raising the temperature of the air flowing through the indoor heat exchanger 23, and then blowing the heated air back into the room to raise the indoor air temperature.

[0069] As shown in Figure 2, in some embodiments, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 4 can be respectively arranged in the receiving space 10 inside the casing 1. In this way, the casing 1 can cover and protect them, preventing the erosion of foreign objects or the impact of external forces from causing structural damage, thereby improving the structural reliability of the air conditioner and ensuring that the air conditioner can work normally.

[0070] As shown in Figure 2, in some embodiments, the internal accommodating space 10 of the casing 1 may include three sub-spaces. These three sub-spaces are, from bottom to top, a first sub-space 110, a second sub-space 120, and a third sub-space 130. The compressor 21 can be housed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 can be housed in the second sub-space 120. The indoor heat exchanger 24 and the indoor fan assembly 4 can be housed in the third sub-space 130. Thus, by using three layers of sub-spaces from bottom to top, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 24 can be distributed at different heights within the casing 1, which helps to increase the overall height of the air conditioner, reduce its width and thickness, and minimize the space occupied by the air conditioner in the operating area.

[0071] As shown in Figures 2 and 3, in some embodiments, the housing 1 may include a chassis 12. The chassis 12 may be located at the bottom of the housing 1. A receiving space 10 may be formed above the chassis 12. The receiving space 10 may be used as an installation space for other components of the air conditioner. The chassis 12 may be used to support other components of the air conditioner.

[0072] As shown in Figures 2 and 3, in some embodiments, the housing 1 may include support feet 13. Support feet 13 may be mounted on the chassis 12. Support feet 13 can increase the contact area between the bottom of the housing 1 and the ground, thereby improving the reliability of the chassis 12 in supporting the air conditioner and enhancing the stability of the air conditioner.

[0073] As shown in Figures 4 and 5, in some embodiments, multiple support feet 13 may be provided. Multiple support feet 13 supporting the chassis 12 can increase the stability and reliability of the chassis 12.

[0074] For example, as shown in Figure 5, there can be four support legs 13. The four support legs 13 can be joined end to end to form a polygonal ring structure. It should be noted that in other embodiments, the number of support legs 13 can be three, five, etc., and this is not limited here.

[0075] As shown in Figures 4 and 5, in some embodiments, the opposite ends of multiple support legs 13 can be sequentially spliced ​​together and continuously arranged around the outer periphery of the chassis 12. It should be noted that the multiple support legs 13 continuously arranged around the outer periphery of the chassis 12 can form a closed ring structure.

[0076] Specifically, one end of each of the opposite ends of a support leg 13 can be spliced ​​with an adjacent support leg 13, and the other end of each of the opposite ends of a support leg 13 can be spliced ​​with another adjacent support leg 13, so that the opposite ends of multiple support legs 13 can be spliced ​​together sequentially to form a structure that surrounds and is circumferentially arranged around the outer periphery of the chassis 12. In this structure, by splicing the support legs 13 together to form a ring structure, compared to the existing structure where each support leg 13 is independent and prone to swaying due to uneven ground or external forces, the overall structure of the end-to-end spliced ​​support legs 13 in this technical solution not only ensures even distribution of force on each support leg 13 but also enhances the overall support strength, preventing individual support legs 13 from becoming loose and affecting stability.

[0077] As shown in Figures 6, 7, and 8, in some embodiments, the two opposite ends of the support leg 13 can be a first end 1301 and a second end 1302, respectively. The first end 1301 of the support leg 13 may be recessed with a snap-fit ​​groove 1303. The second end 1302 of the support leg 13 may be protruded with a positioning part 131. The positioning part 131 can be adapted to the snap-fit ​​groove 1303.

[0078] As shown in Figure 5, the positioning part 131 of the support leg 13 can be aligned and inserted into the snap-fit ​​groove 1303 of an adjacent support leg 13, so that the second end 1302 of the support leg 13 is spliced ​​with the first end 1301 of an adjacent support leg 13. The snap-fit ​​of the support leg 13 can be aligned and inserted into the positioning part 131 of another adjacent support leg 13, so that the first end 1301 of the support leg 13 is spliced ​​with the second end 1302 of another adjacent support leg.

[0079] Specifically, the first end 1301 and the second end 1302 of the support leg 13 are respectively connected to a support leg 13. By inserting the positioning part 131 of the support leg 13 into the snap-fit ​​groove 1303 of an adjacent support leg 13, the positioning part 131 snaps into the snap-fit ​​groove 1303, thereby splicing the second end 1302 of the support leg 13 with the first end 1301 of the adjacent support leg 13. By correspondingly snapping the snap-fit ​​groove 1303 of the support leg 13 into the positioning part 131 of another adjacent support leg 13, the first end 1301 of the support leg 13 is spliced ​​with the second end 1302 of the other adjacent support leg 13. In this way, by inserting the positioning part 131 of adjacent support legs 13 into the corresponding snap-fit ​​groove 1303, the snap-fit ​​splicing method between the support legs 13 does not require the use of tools for installation, reduces the installation difficulty of the support legs 13, simplifies the support structure of the chassis 12, and reduces the difficulty of user operation. Furthermore, the assembled support legs 13 can form a ring-shaped support structure, which not only ensures that the force is evenly distributed among the support legs 13, thus effectively improving the support strength of the support legs 13, but also allows for flexible splicing and combination of the multiple support legs 13, as each support leg 13 has the same structure.

[0080] As shown in Figures 7 and 8, in some embodiments, the first end 1301 of the support leg 13 may be provided with a first engaging portion 132. The first engaging portion 132 may be provided protruding from the side wall of the engaging groove 1303 toward the engaging groove 1303. The positioning portion 131 may be recessed with a first positioning groove 1304. The first positioning groove 1304 may be provided correspondingly to the first engaging portion 132.

[0081] When the positioning part 131 is inserted into the snap-fit ​​groove 1303, the first snap-fit ​​part 132 is embedded in the first positioning groove 1304, so that the positioning part 131 is snapped and fixed in the snap-fit ​​groove 1303.

[0082] Specifically, the first end 1301 of the support leg 13 not only has a snap-fit ​​groove 1303, but also a first snap-fit ​​portion 132 protruding from the side wall of the snap-fit ​​groove 1303 toward the interior of the snap-fit ​​groove 1303. Correspondingly, the positioning portion 131 on the second end 1302 of the support leg 13 not only cooperates with the snap-fit ​​groove 1303, but also has a first positioning groove 1304 recessed on its surface, which corresponds to the first snap-fit ​​portion 132. Thus, when the positioning portion 131 is inserted into the snap-fit ​​groove 1303, the first snap-fit ​​portion 132 can be accurately embedded into the first positioning groove 1304, thereby firmly snapping the positioning portion 131 into the snap-fit ​​groove 1303.

[0083] In this embodiment, the positioning part 131 and the locking groove 1303 are further engaged by the first locking part 132 and the first positioning groove 1304, which further strengthens the splicing structure between adjacent support legs 13, improves the stability of the splicing structure between multiple support legs 13, and helps the support legs 13 to be less prone to loosening or falling off during long-term use. Regarding installation efficiency, when the user inserts the positioning part 131 into the locking groove 1303, as the positioning part 131 moves within the locking groove 1303 until the first locking part 132 engages with the first positioning groove 1304, adjacent support legs 13 are fixed, achieving rapid splicing between support legs 13, greatly simplifying the installation steps and improving installation efficiency.

[0084] As shown in Figures 7 and 8, in some embodiments, the shape and size of the first latching portion 132 can match that of the first positioning groove 1304. For example, the first latching portion 132 can be configured as a triangular structure, and correspondingly, the first positioning groove 1304 can be configured as a recessed triangular groove.

[0085] In some other embodiments, the first engaging portion 132 may also be protruding from the positioning portion 131. The first positioning groove 1304 may also be formed by a recess in the side wall of the engaging groove 1303. The first positioning groove 1304 may be correspondingly provided with the first engaging portion 132, and the first engaging portion 132 may be engaged in the groove.

[0086] As shown in Figures 7 and 8, in some embodiments, the surface of the first engaging portion 132 may form a first guide slope (not shown in the figures). The first guide slope may be inclined toward the first positioning groove 1304. The first guide slope can be used to guide the first engaging portion 132 to engage with the first positioning groove 1304, or to guide the first engaging portion 132 to disengage from the first positioning groove 1304. Specifically, the first guide slope can reduce the frictional resistance during the engagement process of the first engaging portion 132 and the first positioning groove 1304, thereby improving the smoothness of the splicing process of the support leg 13 and further improving the installation efficiency.

[0087] As shown in Figure 4, in some embodiments, the support foot 13 and the chassis 12 can be detachably connected. This allows the user to selectively use the support foot 13 to support the chassis 12. For example, if the chassis 12 is equipped with casters 16, the user can move the air conditioner to its intended position by installing the support foot 13 to secure it. When the user needs to move the air conditioner, the support foot 13 can be detached from the chassis 12, thus avoiding friction between the support foot 13 and the ground and reducing the difficulty of movement.

[0088] As shown in Figure 4, in some embodiments, the support leg 13 and the chassis 12 can be connected by a plug-in structure. The plug-in structure between the support leg 13 and the chassis 12 can reduce the difficulty for users to install and remove the support leg 13, and improve the convenience of use.

[0089] As shown in Figure 4, in some embodiments, the side of the chassis 12 facing the support foot 13 may be provided with a plug-in portion. The plug-in portion can be used to connect with the support foot, so that the support foot 13 is connected to the outer periphery of the chassis 12. The following describes in detail the connection structure between the plug-in portion and the chassis 12, taking the plug-in portion as a plug-in groove 1201 as an example.

[0090] As shown in Figures 4 and 9, in some embodiments, the support leg 13 may have a plug-in post 133 on the side facing the chassis 12. The plug-in post 133 may extend towards the chassis 12. The chassis 12 may have a plug-in groove 1201 on the side facing the support leg 13. The plug-in groove 1201 may extend away from the support leg 13. The plug-in post 133 may be arranged opposite to the plug-in groove 1201.

[0091] The insertion post 133 extends along the support leg 13 towards the chassis 12, allowing for a precise alignment and fixing structure between the support leg 13 and the chassis 12. This enables the support leg 13 to be directly inserted and connected to the chassis 12, reducing the installation difficulty and effectively improving installation efficiency. Furthermore, the support leg 13 is directly inserted into the insertion slot 1201 of the chassis 12 via the insertion post 133, providing a connection and fixing structure between the support leg 13 and the chassis 12. This further prevents the support leg 13 from shifting or falling off due to vibration or external forces. Simultaneously, the insertion structure ensures more even force distribution on the support leg 13, improving its durability.

[0092] As shown in Figures 3 and 4, in some embodiments, multiple insertion slots 1201 may be provided. The multiple insertion slots 1201 are arranged corresponding to the insertion posts 133 of multiple support legs 13. The insertion posts 133 of each support leg 13 are respectively aligned and inserted into the corresponding insertion slot 1201.

[0093] Specifically, multiple insertion slots 1201 can be provided corresponding to the positions of the support feet 13, so that multiple support feet 13 can be inserted into the insertion slots 1201 through insertion posts 133, thereby connecting multiple support feet 13 to the chassis 12.

[0094] As shown in Figures 4 and 5, in some embodiments, the side of the support leg 13 facing the chassis 12 may be provided with multiple plug-in posts 133.

[0095] It should be noted that since the support leg 13 and the chassis 12 are connected by only a single plug-in post 133, the connection is prone to loosening due to external force or vibration. By providing multiple plug-in posts 133 on the support leg 13 and correspondingly providing a number of plug-in slots 1201 on the chassis 12, the number of connection points between the support leg 13 and the chassis 12 can be increased. Multiple plug-in posts 133 of the same support leg 13 are inserted into the corresponding multiple plug-in slots 1201 of the chassis 12, thereby forming a more stable multi-point support structure, effectively preventing each support leg 13 from loosening or shifting from the chassis 12.

[0096] As shown in Figures 4 and 5, in some embodiments, the support leg 13 may have two plug-in posts 133 on the side facing the chassis 12.

[0097] As shown in Figure 4, in some embodiments, the shape and depth of the plug post 133 can match that of the plug groove 1201. For example, the plug post 133 can be a cuboid columnar structure, and correspondingly, the plug groove 1201 can be configured as a cuboid columnar groove.

[0098] As shown in Figures 9 and 10, in some embodiments, the plug-in post 133 may be provided with a protruding second engaging portion 134. The plug-in groove 1201 may be provided with a recessed second positioning groove 1202. The second positioning groove 1202 may be arranged correspondingly to the second engaging portion 134. When the plug-in post 133 is inserted into the plug-in groove 1201, the second engaging portion 134 may be embedded in the second positioning groove 1202, so that the plug-in post 133 is engaged and fixed in the plug-in groove 1201.

[0099] Specifically, by providing a second engaging portion 134 that protrudes from the second engaging portion 134 and a second positioning groove 1202 that is recessed in the insertion groove 1201, the second engaging portion 134 can engage with the second positioning groove 1202, thereby providing an additional connection point for the insertion structure between the insertion post 133 and the chassis 12. This improves the connection strength between the insertion post 133 and the insertion groove 1201 of the chassis 12, preventing the insertion post 133 from loosening or falling out within the insertion groove 1201. In terms of installation efficiency, during the process of inserting the insertion post 133 into the insertion groove 1201, as the insertion post 133 moves within the insertion groove 1201 until the second engaging portion 134 engages with the second positioning groove 1202, the support foot 13 and the chassis 12 are fixed together. This achieves rapid installation between the support foot 13 and the chassis 12, greatly simplifying the installation steps and improving installation efficiency.

[0100] As shown in Figures 4 and 10, in some embodiments, the shape and size of the second latching portion 134 can match that of the second positioning groove 1202. For example, the second latching portion 134 can be configured as a triangular structure, and correspondingly, the second positioning groove 1202 can be configured as a triangular groove.

[0101] As shown in Figure 10, in some embodiments, a second guide slope 1308 may be formed on the surface of the second snap-fit ​​portion 134. The second guide slope 1308 may be inclined toward the second positioning groove 1202. The second guide slope 1308 can be used to guide the second snap-fit ​​portion 134 to engage with the second positioning groove 1202, or to guide the second snap-fit ​​portion 134 to disengage from the second positioning groove 1202. Specifically, the second guide slope 1308 can reduce the frictional resistance during the engagement process of the second snap-fit ​​portion 134 and the second positioning groove 1202, thereby improving the smoothness of the insertion process of the support foot 13 onto the chassis 12 and further improving the installation efficiency.

[0102] In some other embodiments, the insertion slot 1201 may also be provided with a raised second engaging portion 134. The insertion post 133 may also be provided with a recessed second positioning groove 1202. The second positioning groove 1202 may be correspondingly provided with the second engaging portion 134, and the second engaging portion 134 may be engaged within the second positioning groove 1202.

[0103] As shown in Figures 6 and 7, in some embodiments, the plug-in post 133 may include a connecting post 1331. The connecting post 1331 may be connected to the support leg 13. The connecting post 1331 may protrude from the support leg 13 towards the chassis 12. The connecting post 1331 is the main body of the plug-in post 133, and its shape and size may be the same as those of the plug-in slot 1201, allowing the connecting post 1331 to be easily inserted into the plug-in slot 1201 and providing sufficient support when inserted into place.

[0104] As shown in Figures 6, 7, and 10, in some embodiments, the plug-in post 133 may include an extension arm 1332. The extension arm 1332 may be disposed on the connecting post 1331. The extension arm 1332 may have a fixed end 13321 and a suspended end 13322. The fixed end 13321 may be connected to the plug-in post 133. The suspended end 13322 may extend towards the support leg 13. The suspended end 13322 may be provided with a second locking portion 134.

[0105] The fixed end 13321 of the extension arm 1332 is connected to the connecting post 1331, while the suspended end 13322 of the extension arm 1332 extends towards the support foot 13. The suspended end 13322 provides the extension arm 1332 with a certain degree of elasticity and resilience, achieved by setting the second snap-fit ​​part 134 on the suspended end 13322. When the user inserts the connecting post 1331 into the insertion slot 1201, the extension arm 1332 gradually extends into the insertion slot 1201 as the connecting post 1331 moves within it. The second snap-fit ​​part 134 engages with the second positioning slot 1202, exerting a force on the extension arm 1332. The suspended end 13322 of the extension arm 1332 is designed to deform accordingly under force, providing a certain degree of buffering and self-adaptive capability during insertion. In this way, the plug post 133 can adapt to different plug angles and depths when it is inserted into the plug slot 1201, which improves the flexibility of the plugging process.

[0106] As shown in Figures 6 and 10, in some embodiments, the connecting post 1331 may have a through hole 1305. The through hole 1305 can penetrate the connecting post 1331 vertically. The extension arm 1332 can be disposed within the through hole 1305. The fixed end 13321 can be connected to the side wall of the through hole 1305 near the chassis 12. The suspended end 13322 can extend in a direction away from the chassis 12.

[0107] Specifically, the fixed end 13321 of the extension arm 1332 can be located close to the chassis 12 and connected to the side wall of the through hole 1305 near the chassis 12. The suspended end 13322 can extend towards the side of the support foot 13, and the suspended end 13322 can be correspondingly arranged with the through hole 1305. When the second latching part 134 on the extension arm 1332 is inserted into or detached from the second positioning groove 1202, the extension arm 1332 can perform elastic buffering movement within the through hole 1305 due to the reaction force of the chassis 12. Thus, the through hole 1305 allows the extension arm 1332 to bend away from the chassis 12 when subjected to external force, thereby providing the necessary buffering and restoring force for the extension arm 1332. The through hole 1305 can accommodate the extension arm 1332 and allow the extension arm 1332 to undergo elastic slow movement during insertion into or removal from the second positioning groove 1202. This not only improves the smoothness of the insertion between the connecting post and the chassis 12, but also improves the durability and stability of the insertion structure.

[0108] In some embodiments, the through hole 1305 may not penetrate the upper and lower ends of the connecting post 1331. The depth of the through hole 1305 can be adapted to the size and shape of the extension arm 1332, so as to allow the extension arm 1332 to elastically move during insertion into or removal from the second positioning groove 1202.

[0109] As shown in Figures 7 and 10, in some embodiments, the fixed end 13321 of the extension arm 1332 can be located at the lower end of the through hole 1305. The bottom of the suspended end 13322 can be provided with a second snap-fit ​​portion 134, and the bottom wall of the insertion groove 1201 is recessed with a second positioning groove 1202.

[0110] As shown in Figure 6, in some embodiments, the insertion post 133 may include a reinforcing portion 1333. The reinforcing portion 1333 may be connected between the sidewall of the through hole 1305 and the extension arm 1332. By adding the reinforcing portion 1333, the structural strength between the extension arm 1332 and the connecting post 1331 can be improved, thereby improving the reliability of the insertion process between the insertion post 133 and the chassis 12.

[0111] As shown in Figures 4 and 11, in some embodiments, the outer side of the support leg 13 away from the chassis 12 may have an inclined surface 1306. The inclined surface 1306 may extend from the first end 1301 of the support leg 13 to the second end 1302 of the support leg 13. In the top-to-bottom direction, the inclined surface 1306 may be inclined away from the chassis 12. The outer surfaces of multiple support legs 13 may be sequentially spliced ​​end to end to form an annular inclined surface structure 1300. Wherein, the first end 1301 of the support leg 13 extends to the second end 1302 of the support leg 13. When multiple support legs 13 are spliced ​​end to end to form a surrounding structure on the outside of the chassis 12, the first ends 1301 and the second ends 1302 of each inclined surface 1306 are correspondingly spliced ​​to form a continuous outer surface, which can cover the outside of the chassis 12 and improve the appearance.

[0112] In some embodiments, as shown in FIG1, the inclined surface 1306 is inclined away from the chassis 12 in the top-to-bottom direction, that is, the lower end of the inclined surface 1306 extends inclinedly towards the outside of the air conditioner. When multiple support legs 13 are spliced ​​together end to end, an annular inclined surface structure 1300 can be formed. Compared with the current technical solution of supporting the bottom of the chassis 12 by separately setting multiple rod-shaped support legs 13, the annular inclined surface structure 1300 is not only more aesthetically pleasing to users, but also prevents users from being kicked by the support legs 13 when passing by the outside of the air conditioner, thus improving the user experience.

[0113] It should be noted that the annular inclined structure 1300 can also be cone-shaped. That is, the annular inclined structure 1300 is a structure in which the outer surface formed by splicing together multiple inclined surfaces 1306 is the outer peripheral surface of a cone.

[0114] As shown in Figures 6 and 7, in some embodiments, the support foot 13 may be provided with a handle 135. The handle 135 may be formed by an indentation of the inclined surface 1306 toward the inside of the housing 1.

[0115] Since the outer side of the support foot 13, away from the chassis 12, is set as an inclined surface 1306, it may be inconvenient for users to hold it or find a point of leverage during installation and disassembly, thus affecting the use of the support foot 13. In this embodiment, a handle 135 is formed by recessing the inclined surface 1306 of the support foot 13 towards the inner side of the housing 1, making it convenient for users to hold the handle 135 directly during installation, assembly, disassembly, or transportation, reducing the possibility of slipping or difficulty in gripping, and facilitating the installation and disassembly of the support foot 13. Moreover, the handle 135 is formed by the recess of the inclined surface 1306 of the support foot 13, and the handle 135 can be a groove structure. In this way, without adding extra parts to the support foot 13, the setting of the handle 135 does not affect the overall appearance of the support foot 13, thus balancing aesthetics and functionality.

[0116] As shown in Figure 7, in some embodiments, the edges of the handle 135 are designed with rounded edges or anti-slip textures. This can improve the comfort of the user gripping the handle 135.

[0117] As shown in Figure 12, in some embodiments, the air conditioner may include casters 16. The casters 16 may be located at the bottom of the chassis 12. By providing casters 16 at the bottom of the chassis 12, the user can easily push the air conditioner, allowing it to move flexibly and making it suitable for scenarios requiring frequent position adjustments, while reducing manual labor.

[0118] As shown in Figure 12, in some embodiments, the rollers 16 can be multiple.

[0119] As shown in Figure 12, in some embodiments, multiple rollers 16 can be respectively positioned close to the edge of the chassis 12. This reduces the space occupied by the rollers 16 at the bottom, making the overall air conditioner more compact.

[0120] As shown in Figure 12, in some embodiments, the bottom of the chassis 12 may be provided with a receiving portion. The receiving portion is used to accommodate the roller, so that the roller can be movably mounted on the bottom of the chassis 12. The following describes in detail the mounting structure of the chassis 12 and the roller using the receiving groove 1203 as an example of the insertion portion.

[0121] As shown in Figures 9 and 12, in some embodiments, the bottom of the chassis 12 may be provided with a receiving groove 1203. The support foot 13 may be provided with a clearance groove 1307 on the side facing the chassis 12. The support foot 13 may be located outside the roller 16. When the support foot 13 surrounds the outside of the chassis 12, a portion of the roller 16 may be located within the receiving groove 1203, and the remaining portion of the roller 16 may be located within the clearance groove 1307.

[0122] Specifically, by providing a receiving groove 1203 at the bottom of the chassis 12, the roller 16 is partially embedded in the receiving groove 1203 of the chassis 12, thus reducing the overall height and preventing the unit from being raised due to the roller 16. Even during pushing and pulling, this reduces the shaking of the air conditioner and improves the user experience. Moreover, the receiving groove 1203 partially covers the roller 16, which can provide a certain degree of dust protection, reduce the entry of foreign objects into the roller 16, and improve the durability of the roller 16.

[0123] Furthermore, since the support foot 13 and the roller 16 are usually independently installed, there is a problem of structural interference between them, which prevents the roller 16 from fully contacting the ground and affects the movement. By providing a recess 1307 on the side of the support foot 13 facing the chassis 12, and embedding the other part of the roller 16 into the recess 1307, the interference between the roller 16 and the support foot 13 is avoided by making reasonable use of the spatial layout of the support foot 13 and the roller 16, allowing the roller 16 to roll smoothly.

[0124] As shown in Figure 11, in some embodiments, a first mark 136 may be provided on the outer side of the support leg 13. The first mark 136 may be located near the first end 1301 of the support leg 13. A second mark 137 may be provided on the outer side of the support leg 13. The second mark 137 may be located near the second end 1302 of the support leg 13. At the connection point of any two adjacent support legs 13, the first mark 136 and the second mark 137 may be positioned opposite each other. By providing the first mark 136 and the second mark 137 on the outer side of the support leg 13, the markings allow the user to quickly identify the correct splicing direction during installation, thereby improving installation efficiency. Furthermore, by positioning the first mark 136 and the second mark 137 opposite each other at the connection point of adjacent support legs 13, it is beneficial for the user to visually judge whether the splicing is correct, avoiding installation problems caused by incorrect orientation, and thus reducing the installation difficulty for the user during daily use.

[0125] The air conditioner according to the embodiments of this disclosure can also be used to solve the problem of water storage space in the chassis, thereby increasing the water storage space of the air conditioner chassis. In the related air conditioners, the chassis also undertakes the function of collecting and discharging condensate or rainwater to ensure the normal operation of the equipment. The related air conditioner chassis design has certain defects, especially in terms of water storage space. Due to the structural limitations of the chassis, its water storage space is usually small or there is no specially designed water storage area, which easily leads to problems of poor drainage or overflow during rainy weather.

[0126] To address the aforementioned issues, as shown in Figures 13 and 14, some embodiments of the present disclosure provide an air conditioner that may include a housing 1. The housing 1 may be configured as the outer casing of the air conditioner.

[0127] As shown in Figures 13 and 14, in some embodiments, the housing 1 may include a main housing 11. The main housing 11 may extend along the height direction. The height dimension of the main housing 11 may be greater than the left-right width dimension and the front-back width dimension of the main housing 11, so as to increase the height of the housing 1 and reduce the space occupied by the housing 1.

[0128] As shown in Figures 15 and 16, in some embodiments, the housing 1 may include a chassis 12. The chassis 12 may be located at the bottom of the main housing 11. A receiving space 10 may be formed between the top of the chassis 12 and the interior of the main housing 11. This receiving space 10 is used as a mounting space for other components of the air conditioner.

[0129] As shown in Figures 15 and 16, in some embodiments, support feet 13 may be provided on the periphery of the chassis 12. The support feet 13 may extend outward from the chassis 12, and the support feet 13 may be used to increase the contact area between the bottom of the housing 1 and the ground, thereby improving the reliability of the chassis 12 in supporting the air conditioner and improving the stability of the air conditioner.

[0130] As shown in Figures 15 and 16, in some embodiments, multiple support feet 13 can be provided, and the multiple support feet 13 can be connected end to end, so that the multiple support feet 13 are arranged circumferentially around the periphery of the chassis 12. In this way, the multiple support feet 13 can form a ring structure on the outer periphery of the chassis 12, which improves the structural strength between the multiple support feet 13 and forms a complete ring structure; at the same time, it avoids the support feet 13 from bumping into the user and improves the safety of the air conditioner.

[0131] As shown in Figures 15 and 16, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may be located within the casing 1. The refrigerant circulation loop may be located within the accommodating space 10. The refrigerant circulation loop may include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 may serve as a condenser and an evaporator, respectively, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby executing either a cooling cycle or a heating cycle for the air conditioner.

[0132] As shown in Figures 14, 15, and 16, in some embodiments, the air conditioner may include an outdoor fan assembly 3. The outdoor fan assembly 3 may be arranged opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 can be used to introduce outdoor air into the casing 1 for heat exchange with the outdoor heat exchanger 22, forming a heat exchange airflow.

[0133] As shown in Figures 13, 14, and 15, in some embodiments, the air conditioner may include an indoor fan assembly 4. The indoor fan assembly 4 may be arranged opposite to the indoor heat exchanger 23. The indoor fan assembly 4 can be used to introduce indoor air into the casing 1 for heat exchange with the indoor heat exchanger 23, forming a heat exchange airflow.

[0134] As shown in Figures 15 and 16, in some embodiments, the internal accommodating space 10 of the casing 1 may include three sub-spaces. These three sub-spaces are, from bottom to top, a first sub-space 110, a second sub-space 120, and a third sub-space 130. The compressor 21 can be housed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 can be housed in the second sub-space 120. The indoor heat exchanger 23 and the indoor fan assembly 4 can be housed in the third sub-space 130. Thus, by using three layers of sub-spaces from bottom to top, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 4 can be distributed at different heights within the casing 1, which helps to increase the overall height of the air conditioner, reduce its width and thickness, and minimize the space occupied by the air conditioner in the usage area.

[0135] As shown in Figures 14, 15, and 16, in some embodiments, an indoor air inlet 111 may be provided on the outer wall of the casing 1. The indoor air inlet 111 can connect to the outside of the casing 1. The indoor air inlet 111 can connect to the indoor space. The indoor air inlet 111 can be located on the outer wall corresponding to the third subspace 130, and the indoor air inlet 111 can be arranged opposite to the air inlet end of the indoor heat exchanger 23 and the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is running, the indoor fan assembly 4 can draw indoor air into the casing 1 through the indoor air inlet 111 to exchange heat with the indoor heat exchanger 23, and the heat-exchanged air is discharged back into the indoor space outside the casing 1 through the air outlet end of the indoor fan assembly.

[0136] As shown in Figures 13, 15, and 16, in some embodiments, an indoor air outlet 112 may be provided on the outer wall of the housing 1. The indoor air outlet 112 may connect to the outside of the housing 1. The indoor air outlet 112 may connect to the indoor space. The indoor air outlet 112 may be located on the outer wall corresponding to the third subspace 130, and the indoor air outlet 112 may be arranged opposite to the air outlet end of the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is running, the indoor fan assembly 4 draws indoor air through the indoor air inlet 111, exchanges heat with the indoor heat exchanger 23, and then discharges it back into the indoor space outside the housing 1 through the air outlet end of the indoor fan assembly and the indoor air outlet 112.

[0137] As shown in Figures 13 and 15, in some embodiments, an air guide plate 113 may be provided on the outer wall of the housing 1. The air guide plate 113 is rotatably disposed at the indoor air outlet 112. Multiple air guide plates 113 may be provided, and multiple air guide plates 113 may be arranged side by side at the indoor air outlet 112. When the air guide plate 113 rotates, it can open or close the indoor air outlet 112. When the air guide plate 113 rotates to open the indoor air outlet 112, it can also change the air outlet direction of the indoor air outlet 112.

[0138] As shown in Figures 14 and 16, in some embodiments, the air conditioner may include an air inlet duct 14. The air inlet duct 14 may be located in the space outside the casing 1. One end of the air inlet duct 14 may be connected to the air inlet end of the outdoor fan assembly 3. The other end of the air inlet duct 14 may be connected to the outdoor space. The air outlet end of the outdoor fan assembly 3 may be arranged towards the outdoor heat exchanger 22. Thus, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet duct 14, introduce outdoor air into the casing 1, and blow it towards the outdoor heat exchanger 22 to heat or cool it. As shown in Figures 14 and 16, in some embodiments, the air conditioner may include an air outlet duct 15. The air outlet duct 15 may be located in the space outside the casing 1. One end of the air outlet duct 15 may be connected to the internal space of the casing 1. The other end of the air outlet duct 15 may be connected to the outdoor space. Thus, when the outdoor fan assembly 3 is running, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet pipe 14, introduce the outdoor air into the casing 1 and blow it towards the outdoor heat exchanger 22, and then discharge the air inside the casing 1 after flowing through the outdoor heat exchanger 22 into the outdoor space through the air outlet pipe 15, thereby realizing outdoor air circulation.

[0139] It should be noted that in some other embodiments, the air inlet duct 14 can also be used for exhaust, and the air outlet duct 15 can also be used for air intake. The air outlet duct 15 can introduce outdoor air into the housing 1 for heat exchange with the outdoor heat exchanger 22. The heat-exchanged air can then be transported to the outside through the air inlet duct 14 under the action of the outdoor fan assembly 3.

[0140] As shown in Figures 14 and 16, in some embodiments, the air inlet duct 14 and the air outlet duct 15 can be located outside the third subspace 130. A receiving area 140 can be recessed on the upper part of the housing 1 corresponding to the outer wall of the third subspace 130. The air inlet duct 14 and the air outlet duct 15 can be arranged within the receiving area 140, allowing them to be positioned above the second subspace 120, and above the outdoor heat exchanger 22 and the outdoor fan assembly 3.

[0141] As shown in Figures 14 and 16, in some embodiments, the air inlet duct 14 and the air outlet duct 15 can be arranged side-by-side in a receiving area 140 on the outer wall of the housing 1. The lower end of the air inlet duct 14 can communicate with the air inlet end of the outdoor fan assembly 3. The lower end of the air outlet duct 15 can communicate with the second subspace 120 inside the housing 1. The upper ends of the air inlet duct 14 and the upper ends of the air outlet duct 15 can connect to the outdoor space. During the installation of the air conditioner, the air inlet duct 14 and the air outlet duct 15 can be extended and fixed to a wall or window, thereby connecting to the outdoor space.

[0142] As shown in Figures 15 and 16, in some embodiments, the air conditioner may include a first drip tray 5. The first drip tray 5 may be located within the housing 1, in the receiving space 10. The first drip tray 5 may be arranged in the area between the first sub-space 110 and the second sub-space 120. The outdoor heat exchanger 22 may be located above the first drip tray 5. The first drip tray 5 can be used to collect condensate flowing down the outer wall of the outdoor heat exchanger 22. When the air conditioner is in heating mode, the refrigerant can evaporate and absorb heat in the outdoor heat exchanger 22, lowering the surface temperature of the outdoor heat exchanger 22. Water vapor in the air condenses into water upon contact with the condensate, which then falls into the first drip tray 5 at the bottom of the outdoor heat exchanger 22, either collected in the first drip tray 5 or discharged through a drain outlet on the first drip tray 5. This prevents condensate from dripping onto the ground, thus preventing the air conditioner from slipping and posing a risk of slipping and falling.

[0143] As shown in Figures 15 and 16, in some embodiments, the bottom port of the air outlet duct 15 can be arranged in the space above the first water receiving tray 5. When outdoor rainwater enters the housing 1 through the air outlet duct 15, it can be collected by the first water receiving tray 5, preventing the rainwater from flowing directly to other areas inside the housing 1 or seeping out of the housing 1 and flowing to the ground.

[0144] As shown in Figure 16, in some embodiments, a first drain outlet 51 may be provided on the side wall of the first water receiving tray 5. A drain valve 52 may be provided at the first drain outlet 51. The drain valve 52 can block the first drain outlet 51. When the drain valve 52 opens the first drain outlet 51, the first drain outlet 51 can connect to the outside of the first water receiving tray 5, and the water in the first water receiving tray 5 can flow out of the outside of the first water receiving tray 5 through the first drain outlet 51.

[0145] As shown in Figures 14 and 16, in some embodiments, the drain valve 52 can be located outside the housing 1, and the first drain port 51 can be connected to the outside of the housing 1. When the drain valve 52 opens the first drain port 51, the water in the first water receiving tray 5 can flow out to the outside of the housing 1 through the first drain port 51.

[0146] As shown in Figures 15 and 16, in some embodiments, the air conditioner may include a second drip tray 6. The second drip tray 6 may be located within the housing 1, in the receiving space 10. The second drip tray 6 may be arranged in the area between the second sub-space 120 and the third sub-space 130. The indoor heat exchanger 23 may be located above the second drip tray 6. The indoor fan assembly 4 may be located above the second drip tray 6. The second drip tray 6 can be used to collect condensate flowing down the outer wall of the indoor heat exchanger 23. When the air conditioner is cooling, the refrigerant can evaporate and absorb heat in the indoor heat exchanger 23, lowering the surface temperature of the indoor heat exchanger 23. Water vapor in the air condenses into water upon contact with the condenser, which then falls into the second drip tray 6 at the bottom of the indoor heat exchanger 23, either collected in the second drip tray 6 or discharged through a drain outlet on the second drip tray 6. This prevents condensate from dripping onto the ground, thus preventing the air conditioner from slipping and posing a risk of slipping and falling.

[0147] As shown in Figures 15 and 16, in some embodiments, a second drain outlet (not shown) may be provided on the bottom surface of the second water receiving tray 6. The second drain outlet is located above the outdoor heat exchanger 22 and the first water receiving tray 5. The condensate in the second water receiving tray 6 can flow through the second drain outlet onto the outdoor heat exchanger 22, cooling the outdoor heat exchanger 22, and then flow down along the outer wall of the outdoor heat exchanger 22 into the first water receiving tray 5. In this way, the condensate in the second water receiving tray 6 can be discharged into the first water receiving tray 5 for collection, and heat exchange can be performed between the condensate and the outdoor heat exchanger 22 to cool the outdoor heat exchanger 22. For example, when the air conditioner is cooling, the outdoor heat exchanger 22, as a condenser, needs to dissipate heat to the outside, while the indoor heat exchanger 23, as an evaporator, needs to absorb heat to the outside. Air condenses into condensate on the surface of the indoor heat exchanger 23. The condensate can flow along the surface of the indoor heat exchanger 23 into the second water collection pan 6, and then through the second drain outlet of the second water collection pan 6 to the outer wall of the outdoor heat exchanger 22, dissipating heat and cooling the outdoor heat exchanger 22. Finally, it flows down the outer wall of the outdoor heat exchanger 22 into the first water collection pan 5 for collection.

[0148] As shown in Figures 15 and 16, in some embodiments, the air conditioner may include a housing 1, which includes a main housing 11 and a chassis 12, forming an internal receiving space 10. The air conditioner may include a refrigerant circulation loop disposed within the receiving space and including a compressor 21, a condenser, and an evaporator connected end-to-end. One of the condenser and evaporator is an outdoor heat exchanger 22, and the other is an indoor heat exchanger 23. The air conditioner may include an outdoor fan assembly 3, disposed on one side of the outdoor heat exchanger 22 to drive outdoor air to flow through the outdoor heat exchanger 22 for heat exchange. The air conditioner may include an indoor fan assembly 4, disposed on one side of the indoor heat exchanger 23 to drive indoor air to flow through the indoor heat exchanger 23 for heat exchange. The air conditioner may include a first drip tray 5, with the outdoor heat exchanger 22 disposed above the first drip tray 5. The air conditioner may include a second drip tray 6, with the indoor heat exchanger 23 disposed above the second drip tray 6. The second drip tray 6 is positioned above the outdoor heat exchanger 22. The air conditioner may include an air inlet duct 14, which delivers outdoor air to the outdoor heat exchanger 22 for heat exchange. The air conditioner may also include an air outlet duct 15, which delivers the heat-exchanged air to the outside under the action of the outdoor fan assembly 3. The air inlet and outlet ducts are positioned above the outdoor heat exchanger and are horizontally spaced from the indoor fan assembly. The compressor is located at the bottom of the casing, and the first drip tray is positioned above the compressor.

[0149] As shown in Figures 16 and 17, in some embodiments, the air conditioner may include a first air duct component 35. The first air duct component 35 may be disposed within the main housing 11. The first air duct component 35 may be disposed within the receiving space 10. The first air duct component 35 may be used to support the internal structure of the air conditioner. For example, the first air duct component 35 may be used to support the outdoor heat exchanger 22, the outdoor fan assembly 3, the first water collection tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, the second water collection tray 6, etc., thereby increasing the structural strength and stability of the air conditioner's internal structure.

[0150] As shown in Figures 16 and 17, in some embodiments, the lower part of the first air duct component 35 can be located within the first subspace 110, and the bottom end of the first air duct component 35 can be supported and fixed on the chassis 12. The upper part of the first air duct component 35 can be located within the second subspace 120, and the top end of the first air duct component 35 can be supported at the bottom of the second water receiving tray 6, facilitating the installation of the indoor heat exchanger 23 and the indoor fan assembly 4 on the second water receiving tray 6. This allows the indoor heat exchanger 23 and the indoor fan assembly 4 to be supported by the second water receiving tray 6 at the top end of the first air duct component 35, thereby improving the structural stability of the indoor heat exchanger 23 and the indoor fan assembly 4 within the third subspace 130.

[0151] As shown in Figures 16 and 17, in some embodiments, the first water receiving tray 5 can be supported and fixed to the upper part of the first air duct component 35, facilitating the installation of the outdoor heat exchanger 22 on the first water receiving tray 5 and its support and fixation to the first air duct component 35. The outdoor fan assembly 3 can be located on the upper part of the first air duct component 35. This facilitates the improvement of the structural stability of the outdoor heat exchanger 22 and the outdoor fan assembly 3 within the second subspace 120.

[0152] It should be noted that in some other embodiments, the first air duct component 35 can also be used to support any one or more of the outdoor heat exchanger 22, outdoor fan assembly 3, first water receiving tray 5, indoor heat exchanger 23, indoor fan assembly 4, and second water receiving tray 6. For example, the first air duct component 35 can also be used to support the outdoor heat exchanger 22 and / or the indoor heat exchanger 23 alone.

[0153] As shown in Figures 16 and 17, in some embodiments, the outdoor fan assembly 3 may include a second air duct component 31. An air duct section 351 may be formed on the upper part of the first air duct component 35. The second air duct component 31 may be fixed to the air duct section 351, and the second air duct component 31 and the air duct section 351 may be joined to form a complete volute structure. An outdoor air duct is formed within the volute structure. The volute structure has an air inlet end and an air outlet end. The air inlet end of the volute structure connects to the air inlet pipe 14, thereby connecting to the outdoor space. The air outlet end of the volute structure connects to the second subspace 120 and is arranged towards the outdoor heat exchanger 22.

[0154] As shown in Figures 16 and 17, in some embodiments, the outdoor fan assembly 3 may include an outdoor fan (not shown in the figures). The outdoor fan may be rotatably disposed inside the volute structure. That is, the outdoor fan may be rotatably disposed inside the outdoor air duct. When the outdoor fan rotates, wind force can be generated inside the volute structure, allowing air from the outdoor space to enter the volute structure through the air inlet pipe 14, i.e., into the outdoor air duct.

[0155] As shown in Figures 16 and 17, in some embodiments, the outdoor fan assembly 3 may include an outdoor motor 32. The outdoor motor 32 can be fixed to the outside of the second duct component 31, with its output shaft extending into the volute structure and drivingly connected to the outdoor fan. Thus, the outdoor motor 32 can drive the outdoor fan to rotate inside the volute structure, thereby drawing air from the outdoor space into the volute structure through the air inlet pipe 14 and blowing it into the second sub-space 120 to contact and exchange heat with the outdoor heat exchanger 22. The heat-exchanged air can then flow to the outside through the air outlet pipe 15. This solution integrates part of the volute structure of the outdoor fan assembly 3 onto the first duct component 35, which can greatly improve the structural strength and stability of the outdoor fan assembly 3, effectively ensuring its stable operation.

[0156] As shown in Figures 16 and 17, in some embodiments, the lower part of the first air duct component 35 may include a support plate 352. The support plate 352 may be arranged laterally within the first subspace 110. The upper end of the support plate 352 may be integrally connected to the lower end of the air duct portion 351. The lower end of the support plate 352 may be supported and fixed on the chassis 12. The lateral width of the support plate 352 may be substantially the same as the lateral width of the air duct portion 351, so that the air duct portion 351 can be supported on the chassis 12 by the support plate 352, further improving the structural strength and structural stability of the outdoor fan assembly 3.

[0157] It should be noted that in some other embodiments, the upper and lower parts of the first air duct component 35 can also be separate structures, that is, the air duct part 351 and the support plate 352 can also be separate structures. The air duct part 351 can be detachably fixed to the upper end of the support plate 352.

[0158] As shown in Figures 16, 18, and 19, in some embodiments, the lower part of the first air duct component 35 may include a first support wall 353 and a second support wall 354. The first support wall 353 may extend from one lateral end of the support plate 352 toward one side of the support plate 352. The second support wall 354 may extend from the other lateral end of the support plate 352 toward the same side of the support plate 352. The lower ends of the first support wall 353 and the second support wall 354 may be supported and fixed on the chassis 12. The first water receiving tray 5 may be simultaneously supported and fixed on the support plate 352, the first support wall 353, and the second support wall 354, thereby improving the support reliability of the first water receiving tray 5 and improving the structural stability of the first water receiving tray 5. In addition, the support plate 352, the first support wall 353, and the second support wall 354 may form a frame-like three-sided structure, which can effectively improve the structural strength of the lower part of the first air duct component 35 and further improve the structural strength and structural stability inside the air conditioner.

[0159] As shown in Figures 18 and 20, in some embodiments, a support portion 121 may be provided on the top surface of the chassis 12. The bottom end of the first air duct component 35 may be supported on the support portion 121. The support plate 352, the first support wall 353, and the second support wall 354 at the lower part of the first air duct component 35 may be supported on the support portion 121 respectively, thereby improving the support stability of the lower part of the first air duct component 35.

[0160] As shown in Figures 18, 20, and 21, in some embodiments, the support portion 121 may include a first support rib 1211 and a second support rib 1212 arranged at intervals. The first support rib 1211 may protrude from the top surface of the chassis 12. The second support rib 1212 may protrude from the top surface of the chassis 12 and be arranged at intervals relative to the first support rib 1211. A support groove 1213 may be formed between the first support rib 1211 and the second support rib 1212. The bottom end of the first air duct component 35 may be inserted into the support groove 1213, and the opposite side walls of the bottom end of the first air duct component 35 shall be supported on the first support rib 1211 and the second support rib 1212 respectively, thereby improving the structural strength and structural stability of the connection between the bottom end of the first air duct component 35 and the chassis 12, and enhancing the reliability of the support portion 121 for the first air duct component.

[0161] Specifically, the lower end of the support plate 352 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the support plate 352 are respectively supported on the first support rib 1211 and the second support rib 1212; the lower end of the first support wall 353 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the first support wall 353 are respectively supported on the first support rib 1211 and the second support rib 1212; the lower end of the second support wall 354 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the second support wall 354 are respectively supported on the first support rib 1211 and the second support rib 1212.

[0162] As shown in Figures 18, 20, and 22, in some embodiments, the support groove 1213 may include a first groove portion 12131. The first groove portion 12131 may be arranged to extend laterally. The bottom end of the first air duct component 35 may be inserted into the first groove portion 12131. The lower end of the support plate 352 may be inserted and fixed into the first groove portion 12131, thereby improving the structural strength and connection stability of the lower end of the support plate 352 and the entire bottom end of the first air duct component 35.

[0163] As shown in Figures 18 and 22, in some embodiments, the support groove 1213 may include a second groove portion 12132. The second groove portion 12132 may extend from one end of the first groove portion 12131 along its length toward one side of the first groove portion 12131. The bottom end of the first air duct component 35 may be inserted into the second groove portion 12132. The lower end of the first support wall 353 may be inserted and fixed into the second groove portion 12132, thereby improving the structural strength and connection stability of the lower end of the first support wall 353 and the entire bottom end of the first air duct component 35.

[0164] As shown in Figures 18 and 22, in some embodiments, the support groove 1213 may include a third groove portion 12133. The third groove portion 12133 may extend from the other end of the first groove portion 12131 along the same side as the first groove portion 12131. The bottom end of the first air duct component 35 may be inserted into the third groove portion 12133. The lower end of the second support wall 354 may be inserted and fixed into the third groove portion 12133, thereby improving the structural strength and connection stability of the lower end of the second support wall 354 and the entire bottom end of the first air duct component 35.

[0165] As shown in Figures 18, 20, and 22, in some embodiments, a first water collection tank 124 may be provided on the top surface of the chassis 12. The first water collection tank 124 may be located on one side of the support portion 121. The first water collection tank 124 may be used to collect rainwater or condensate from inside the casing 1.

[0166] As shown in Figures 18, 20, and 22, in some embodiments, a second water collection tank 125 may be provided on the top surface of the chassis 12. The second water collection tank 125 may be located on the other side of the support portion 121. The first water collection tank 124 and the second water collection tank 125 may be located on opposite sides of the support portion 121. The second water collection tank 125 may also be used to collect and receive rainwater or condensate from inside the casing 1. The cooperation of the first water collection tank 124 and the second water collection tank 125 can effectively increase the water storage space of the chassis 12. Given that the first air duct component 35 needs to be supported on the chassis 12, the structural arrangement of the first water collection tank 124 and the second water collection tank 125 can effectively improve the space utilization efficiency of the chassis 12, thereby reasonably expanding the water storage space of the chassis 12.

[0167] As shown in Figures 18, 20, and 22, in some embodiments, the first groove 12131 can be arranged laterally between the first water collection tank 124 and the second water collection tank 125. The second groove 12132 can extend from one end of the first groove 12131 toward one side of the first water collection tank 124. The third groove 12133 can extend from the other end of the first groove 12131 toward one side of the first water collection tank 124. In this way, the second groove 12132 and the third groove 12133 can be arranged on the same side of the first groove 12131, which facilitates the bottom of the first air duct component 35 to be fixed to the first groove 12131, the second groove 12132, and the third groove 12133 respectively, forming a frame-type three-sided fixing structure, effectively improving the structural strength and connection stability of the bottom of the entire first air duct component 35.

[0168] As shown in Figures 18, 20, and 21, in some embodiments, the chassis 12 may be provided with a connecting channel 122 penetrating the support portion 121. One end of the connecting channel 122 may be connected to the first water collection tank 124. The other end of the connecting channel 122 may be connected to the second water collection tank 125. The connecting channel 122 connects the first water collection tank 124 and the second water collection tank 125, allowing rainwater or condensate in the first water collection tank 124 to enter the second water collection tank 125 through the connecting channel 122, and rainwater or condensate in the second water collection tank 125 to enter the first water collection tank 124 through the connecting channel 122. This fully utilizes the water storage space of the first water collection tank 124 and the second water collection tank 125, improving the storage effect of rainwater or condensate, thereby effectively enhancing and efficiently utilizing the water storage space of the chassis 12.

[0169] As shown in Figures 18, 23, and 24, in some embodiments, the first water collection tank 124 may be located on the side of the first support rib 1211 away from the second support rib 1212. The second water collection tank 125 may be located on the side of the second support rib 1212 away from the first support rib 1211. The connecting channel 122 may be arranged to pass through the first support rib 1211, the support groove 1213, and the second support rib 1212 in sequence. Furthermore, the connecting channel 122 may be isolated from the support groove 1213, that is, the connecting channel 122 may be isolated from the first groove 12131. In this way, while connecting the first water collection tank 124 and the second water collection tank 125 through the connecting channel 122, water in the first water collection tank 124 and the second water collection tank 125 can be prevented from entering the first tank portion 12131 of the support tank 1213, and water can be prevented from remaining in the support tank 1213.

[0170] As shown in Figures 20, 21, and 22, in some embodiments, the first water collection tank 124 may include a plurality of first water collection units 1241. The plurality of first water collection units 1241 are all disposed on the same side of the support portion 121, that is, on the side of the support portion 121 away from the second water collection tank 125. One end of the connecting channel 122 may communicate with one of the first water collection units 1241, thereby facilitating the connection of the remaining plurality of first water collection units 1241 through that first water collection unit 1241.

[0171] As shown in Figures 20, 21, and 22, in some embodiments, a first partition plate 1242 may be provided inside the first water collection tank 124, which can divide the first water collection tank 124 into multiple first water collection units 1241. Multiple first partition plates 1242 may be provided, and each of the multiple first partition plates 1242 may be located between different adjacent first water collection units 1241. One or more first partition plates 1242 facilitate the division of the first water collection tank 124 into multiple first water collection units 1241, making it easier to collect rainwater or condensate in each of the first water collection units 1241.

[0172] As shown in Figures 20 and 21, in some embodiments, a first overflow port 1243 may be provided on the first partition plate 1242. The first overflow port 1243 can be connected to the first water collection units 1241 on both sides of the first partition plate 1242. In this way, adjacent first water collection units 1241 can be interconnected through the first overflow port 1243. When the water level of rainwater or condensate in one of the first water collection units 1241 is higher than the first overflow port 1243, it can flow through the first overflow port 1243 to the adjacent first water collection unit 1241, thereby making full use of the water storage space of each first water collection unit 1241.

[0173] As shown in Figures 20 and 21, in some embodiments, the first overflow port 1243 may be located at the top edge of the first partition plate 1242. Alternatively, the first overflow port 1243 may be located at the bottom edge of the first partition plate 1242. Alternatively, the first overflow port 1243 may be located at other positions on the first partition plate 1242.

[0174] As shown in Figures 20, 21, and 22, in some embodiments, the second water collection tank 125 may include a plurality of second water collection units 1251. The plurality of second water collection units 1251 are all disposed on the same side of the support portion 121, that is, on the side of the support portion 121 away from the first water collection tank 124. The other end of the connecting channel 122 may communicate with one of the second water collection units 1251, thereby facilitating the connection of the remaining plurality of second water collection units 1251 through that second water collection unit 1251.

[0175] As shown in Figures 20, 21, and 22, in some embodiments, a second partition plate 1252 may be provided inside the second water collection tank 125, which can divide the second water collection tank 125 into multiple second water collection units 1251. Multiple second partition plates 1252 may be provided, and each of the multiple second partition plates 1252 may be located between different adjacent second water collection units 1251. Using one or more second partition plates 1252 facilitates the division of the second water collection tank 125 into multiple second water collection units 1251, making it easier to collect rainwater or condensate in each of the multiple second water collection units 1251.

[0176] As shown in Figures 20 and 21, in some embodiments, a second overflow port 1253 may be provided on the second partition plate 1252. The second overflow port 1253 can be connected to the second water collection units 1251 on both sides of the second partition plate 1252. In this way, adjacent second water collection units 1251 can be interconnected through the second overflow port 1253. When the water level of rainwater or condensate in one of the second water collection units 1251 is higher than that of the first overflow port 1243, it can flow through the second overflow port 1253 into the adjacent second water collection unit 1251, thereby making full use of the water storage space of each second water collection unit 1251.

[0177] As shown in Figures 20 and 21, in some embodiments, the second overflow port 1253 may be located at the top edge of the second partition plate 1252. Alternatively, the first overflow port 1243 may be located at the bottom edge of the second partition plate 1252. Alternatively, the second overflow port 1253 may be located at other positions on the second partition plate 1252.

[0178] As shown in Figures 20 and 21, in some embodiments, a step 126 may be provided inside the second water collection tank 125. A drain outlet 1261 may be provided on the top surface of the step 126. This drain outlet 1261 can connect to the space below the bottom of the chassis 12. Thus, when the water level in the second water collection tank 125 is higher than the top of the drain outlet 1261, excess condensate or rainwater in the second water collection tank 125 can be discharged to the outside of the casing 1 through the drain outlet 1261; excess condensate or rainwater in the first water collection tank 124 can first enter the second water collection tank 125, and then be discharged to the outside of the casing 1 through the drain outlet 1261. When there is a large amount of rainwater or condensate, and the first and second water collection tanks 124 cannot hold more water, excess water on the chassis 12 can be discharged through the drain outlet 1261, preventing excessive accumulation of rainwater or condensate inside the casing 1.

[0179] In some other embodiments, the step portion 126 and the outlet 1261 may also be provided in the first water collection tank 124. Alternatively, multiple steps 126 and outlets 1261 may be provided, with multiple steps 126 and corresponding outlets 1261 respectively provided in the first water collection tank 124 and the second water collection tank 125.

[0180] As shown in Figures 20 and 21, in some embodiments, the exhaust port 1261 can also be used as a heat dissipation vent, and the air below the bottom of the chassis 12 can enter the interior of the housing 1 through the exhaust port 1261 to dissipate heat from the internal components of the housing 1.

[0181] As shown in Figures 15, 20, and 21, in some embodiments, the chassis 12 may be provided with a partition rib 123. A mounting groove 1231 may be formed within the partition rib 123. The bottom end of the compressor 21 is installed within the mounting groove 1231. The mounting groove 1231 may be located on the side of the support portion 121 near the first water collection tank 124, allowing the compressor 21 to be arranged in the space of the support plate 352 within the first subspace 110 on the side near the first water collection tank 124.

[0182] As shown in Figures 20 and 21, in some embodiments, the first water collection tank 124 is disposed adjacent to the outer periphery of the mounting groove 1231. An overflow groove 1232 may be provided at the top edge of the isolation rib 123. The overflow groove 1232 may connect the mounting groove 1231 and the first water collection tank 124. The overflow groove 1232 may connect the mounting groove 1231 and the adjacent first water collection unit 1241. When the water level in the first water collection tank 124 and the first water collection unit 1241 adjacent to the mounting groove 1231 is higher than the overflow groove 1232, excess rainwater or condensate in the first water collection tank 124 can also be discharged into the mounting groove 1231 through the overflow groove 1232, thereby collecting rainwater or condensate in the mounting groove 1231 or discharging it outside the chassis 12 through the mounting groove 1231.

[0183] In some embodiments, a drain outlet may also be provided in the mounting groove 1231. Excess water in the mounting groove 1231 can also be discharged to the outside of the chassis 12 through the corresponding drain outlet.

[0184] As shown in Figures 15 and 16, in some embodiments, the air conditioner may include an electrical control box 8. The electrical control box 8 may be located inside the housing 1. The electrical control box 8 may be electrically connected to the compressor 21, the outdoor fan assembly 3, and the indoor fan assembly 4, respectively. Thus, the electrical control box 8 can control the on / off circuits of the compressor 21, the outdoor fan assembly 3, and the indoor fan assembly 4, thereby controlling the normal operation of the air conditioner.

[0185] As shown in Figures 15 and 16, in some embodiments, the electrical control box 8 can be located within the first subspace 110. The electrical control box 8 can be located on the side of the support portion 121 near the second water collection tank 125. The electrical control box 8 can be supported above the second water collection tank 125. In this way, the electrical control box 8 and the compressor 21 can be arranged on opposite sides of the first air duct component 35, facilitating a rational layout and effective utilization of the internal space of the housing 1.

[0186] As shown in Figures 15, 16, and 17, in some embodiments, a drainage hole 33 may be provided on the inner bottom surface of the volute structure of the outdoor fan assembly 3. The drainage hole 33 may be located on the inner bottom surface of the duct section 351, or it may be located on the inner bottom surface of the second duct component 31. When it rains outdoors, rainwater easily enters the volute structure through the inlet pipe. The rainwater entering the volute structure can be discharged promptly through the drainage hole 33, and then flows downwards through the outer wall of the first duct component 35 to the chassis 12, where it is collected. Through the design and reasonable arrangement of the drainage structure inside the volute structure, rainwater accumulation inside the volute structure can be effectively prevented, ensuring the stable operation of the outdoor fan assembly 3.

[0187] In some other embodiments, when the air conditioner is heating, the condensate generated in the outdoor fan assembly 3 can also be discharged in time through the drain hole 33. It can flow down through the outer wall of the first air duct 35 to the chassis 12 and be collected on the chassis 12, effectively preventing the condensate from accumulating in the volute structure and ensuring the stable operation of the outdoor fan assembly 3.

[0188] The air conditioner disclosed in this embodiment can also be used to solve the heat dissipation problem of the reactor, thereby improving the heat dissipation effect and efficiency of the reactor in the air conditioner. Related air conditioners typically include a reactor, which can perform functions such as filtering, stabilizing current and voltage, improving power factor, or suppressing surge current. The reactor in related air conditioners is usually mounted on the chassis with a protective cover for protection and heat dissipation. However, its heat dissipation efficiency depends on the airflow within the air conditioner's internal space. An unreasonable layout of internal components can easily lead to poor heat dissipation of the reactor.

[0189] To address the aforementioned issues, as shown in Figures 13 and 14, some embodiments of the present disclosure provide an air conditioner that may include a housing 1. The housing 1 may be configured as the outer casing of the air conditioner.

[0190] As shown in Figures 13 and 14, in some embodiments, the housing 1 may include a main housing 11.

[0191] As shown in Figures 15 and 16, in some embodiments, the housing 1 may include a chassis 12. The chassis 12 may be located at the bottom of the main housing 11. A receiving space 10 may be formed between the top of the chassis 12 and the interior of the main housing 11.

[0192] As shown in Figures 15 and 16, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may be located within the casing 1. The refrigerant circulation loop may be located within the accommodating space 10. The refrigerant circulation loop may include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 may serve as a condenser and an evaporator, respectively, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby executing either a cooling cycle or a heating cycle for the air conditioner.

[0193] As shown in Figures 16 and 25, in some embodiments, the air conditioner may include a first air duct component 35. The first air duct component 35 may be disposed within the main housing 11. The first air duct component 35 may be disposed within the receiving space 10. The first air duct component 35 may be used to support the internal structure of the air conditioner. For example, the first air duct component 35 may be used to support the outdoor heat exchanger 22, the outdoor fan assembly 3, the first water collection tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, the second water collection tray 6, etc., thereby increasing the structural strength and stability of the air conditioner's internal structure.

[0194] As shown in Figures 17 and 26, in some embodiments, a support portion 121 may be provided on the top surface of the chassis 12. The bottom end of the first air duct component 35 may be supported on the support portion 121. The support plate 352, the first support wall 353, and the second support wall 354 at the lower part of the first air duct component 35 may be supported on the support portion 121 respectively, thereby improving the support stability of the lower part of the first air duct component 35.

[0195] As shown in Figures 26, 27, and 29, in some embodiments, a water collection tank 100 may be provided on the top surface of the chassis 12. The water collection tank 100 may be located in the bottom area of ​​the accommodating space 10. The water collection tank 100 may be used to collect and collect rainwater or condensate from inside the housing 1.

[0196] As shown in Figures 29 and 30, in some embodiments, multiple water collection tanks 100 may be provided, and the multiple water collection tanks 100 may include a first water collection tank 124 and a second water collection tank 125. The first water collection tank 124 may be provided on one side of the support portion 121. The second water collection tank 125 may be provided on the other side of the support portion 121. The first water collection tank 124 and the second water collection tank 125 may be respectively provided on opposite sides of the support portion 121. Both the first water collection tank 124 and the second water collection tank 125 can be used to receive and collect rainwater or condensate water inside the casing 1. The cooperation of the first water collection tank 124 and the second water collection tank 125 can effectively increase the water storage space of the chassis 12. Under the premise that the first air duct component 35 needs to be supported on the chassis 12, the structural arrangement of the first water collection tank 124 and the second water collection tank 125 can effectively improve the space utilization efficiency of the chassis 12, thereby reasonably expanding the water storage space of the chassis 12.

[0197] It should be noted that in some other embodiments, the plurality of water collection tanks 100 may also include a third water collection tank or a fourth water collection tank, etc. The number and position of the water collection tanks 100 other than the first water collection tank 124 and the second water collection tank 125 can be adjusted as needed.

[0198] As shown in Figures 27, 28, and 29, in some embodiments, the chassis 12 may be provided with a connecting channel 122 penetrating the support portion 121. One end of the connecting channel 122 may be connected to the first water collection tank 124. The other end of the connecting channel 122 may be connected to the second water collection tank 125. The connecting channel 122 connects the first water collection tank 124 and the second water collection tank 125, allowing rainwater or condensate in the first water collection tank 124 to enter the second water collection tank 125 through the connecting channel 122, and rainwater or condensate in the second water collection tank 125 to enter the first water collection tank 124 through the connecting channel 122. This fully utilizes the water storage space of the first water collection tank 124 and the second water collection tank 125, improving the storage effect of rainwater or condensate, thereby effectively enhancing and efficiently utilizing the water storage space of the chassis 12.

[0199] As shown in Figures 25 and 26, in some embodiments, the air conditioner may include an electrical control box 8.

[0200] As shown in Figures 26 and 27, in some embodiments, the air conditioner may include a reactor assembly 9. The reactor assembly 9 may include a reactor 91. The reactor assembly 9 may be disposed within a receiving space 10 inside the housing 1. The reactor assembly 9 may be disposed within a first subspace 110. The reactor assembly 9 may be disposed on one side of the electrical control box 8. The reactor assembly 9 may be disposed above the chassis 12. The reactor 91 may be electrically connected to components such as the main control board within the electrical control box 8. The reactor 91 may function to filter, stabilize current and voltage, improve power factor, or suppress surge current, etc.

[0201] As shown in Figures 26 and 32, in some embodiments, the reactor assembly 9 may include a mounting base 92. The mounting base 92 may be located above the chassis 12. The mounting base 92 may be located within the first subspace 110. The mounting base 92 may be located on one side of the electrical control box 8. The reactor 91 may be fixed to the mounting base 92, thereby fixing the reactor 91 inside the housing 1 via the mounting base 92.

[0202] As shown in Figures 26 and 32, in some embodiments, the mounting base 92 can be fixed to the side wall of the first air duct component 35. The reactor 91 can be fixed to the side wall of the first air duct component 35 by the mounting base 92, thereby improving the structural stability and reliability of the reactor assembly 9 inside the housing 1.

[0203] As shown in Figures 28, 29, and 32, in some embodiments, the mounting base 92 may include a heat sink 93. The heat sink 93 may extend downward from the bottom end of the mounting base 92. A water collection tank 100 may be arranged below the reactor assembly 9. The lower end of the heat sink 93 may extend into the water collection tank 100, allowing the lower end of the heat sink 93 to contact the water in the water collection tank 100, thereby dissipating heat from the reactor 91 through rainwater or condensate in the water collection tank 100. Specifically, the heat of the reactor 91 can be transferred to the heat sink 93 through the mounting base 92, and then the heat sink 93 dissipates heat from the reactor 91; by extending the lower end of the heat sink 93 into the water collection tank 100, the rainwater or condensate in the water collection tank 100 can improve the heat dissipation efficiency of the heat sink 93, thereby effectively improving the heat dissipation effect and efficiency of the reactor 91. Through the structural design of the heat sink 93, the mounting base 92 can not only fix the reactor 91, but also realize the heat transfer efficiency and heat dissipation efficiency of the reactor 91.

[0204] As shown in Figures 31, 32, and 33, in some embodiments, the mounting base 92 and the heat sink 93 can be made of metal or other thermally conductive materials. The mounting base 92 and the heat sink 93 can be a single integrated structure. This improves the heat transfer efficiency between the heat sink 93 and the reactor 91.

[0205] As shown in Figures 32 and 33, in some embodiments, the mounting base 92 may include a mounting side plate 921, which can be fixed to the side wall of the reactor 91. The mounting side plate 921 can make surface contact with the side wall of the reactor 91, improving the heat transfer efficiency between the reactor 91 and the mounting side plate 921, thereby transferring more heat to the heat sink 93 and improving the heat dissipation performance of the reactor 91.

[0206] As shown in Figures 32 and 33, in some embodiments, the heat sink 93 can extend downward from the lower end of the mounting side plate 921. The heat of the reactor 91 can be transferred to the heat sink 93 through the mounting side plate 921. This structural layout can achieve effective heat dissipation of the reactor 91 and optimize the overall heat dissipation performance of the reactor 91.

[0207] As shown in Figures 32 and 33, in some embodiments, the heat sink 93 may be arranged to extend vertically downward from the lower edge of the mounting side plate 921. In other embodiments, the heat sink 93 may also be arranged to extend downward from the lower edge of the mounting side plate 921 at other angles.

[0208] As shown in Figures 31 and 33, in some embodiments, the heat sink 93 may be provided with a recessed reinforcing groove 931. The reinforcing groove 931 can be formed on the side wall of the heat sink 93 by mechanical stamping, so that reinforcing ribs 932 can be formed on the opposite side of the heat sink 93, thereby improving the structural strength of the heat sink 93.

[0209] As shown in Figures 31 and 33, in some embodiments, the reinforcing groove 931 can extend vertically. The extending direction of the reinforcing groove 931 can be consistent with the extending direction of the heat sink 93. The upper end of the reinforcing groove 931 extends upward into the mounting side plate 921. Thus, one end of the reinforcing groove 931 can be arranged on the heat sink 93, and the other end of the reinforcing groove 931 can extend onto the mounting side plate 921, so that the reinforcing rib 932 formed on the other side wall of the heat sink 93 can extend to the heat sink 93 and the mounting side plate 921 respectively, thereby improving the connection strength between the heat sink 93 and the mounting side plate 921 through the reinforcing groove 931.

[0210] It should be noted that in some other embodiments, reinforcing ribs 932 may be directly protruded from the heat sink 93. The upper end of the reinforcing rib 932 may extend upward into the mounting side plate 921.

[0211] As shown in Figures 26, 31, and 33, in some embodiments, the mounting side plate 921 can be fixed to the side wall of the first air duct component 35. Thus, the reactor 91 can be fixed to the side wall of the first air duct component 35 by the mounting side plate 921, thereby improving the structural strength and stability of the reactor 91 within the housing 1.

[0212] As shown in Figures 26, 32, and 33, in some embodiments, the reactor 91 may be provided with a first fixing hole 911. The first fixing hole 911 can be arranged through the reactor. The mounting side plate 921 may be provided with a second fixing hole 9211, which can be arranged through the mounting side plate 921. The second fixing hole 9211 can be arranged opposite to the first fixing hole 911. In this way, by using screws or bolts passing through the first fixing hole 911 and the second fixing hole 9211, the reactor 91 and the mounting side plate 921 can be simultaneously fixed to the side wall of the first air duct component 35, improving the structural stability of the reactor 91 and the mounting side plate 921, and thus improving the overall structural stability of the reactor assembly 9.

[0213] As shown in Figures 32 and 33, in some embodiments, the reactor 91 may have a side portion 912 protruding from opposite sides of the end facing the mounting side plate 921. A first fixing hole 911 may be provided on the side portion 912. At least one first fixing hole 911 may be provided on each of the two side portions 912. Correspondingly, a corresponding number of second fixing holes 9211 may be provided on the side wall of the mounting side plate 921. In this way, the reactor 91 can be fixed to the mounting side plate 921 via the side portions 912, and the stability of the reactor 91 is improved by utilizing the two side portions 912 in conjunction with the multiple first fixing holes 911 and the multiple second fixing holes 9211.

[0214] As shown in Figures 32 and 33, in some embodiments, a buckle 9212 may be protruding on the side wall of the mounting side plate 921 facing the reactor 91. The buckle 9212 can be snapped onto the side portion 912. Through the snap-fit ​​cooperation between the buckle 9212 and the side portion 912, the reactor 91 is limited so that the first fixing hole 911 and the second fixing hole 9211 are aligned, thereby improving the installation and fixing efficiency of the reactor 91.

[0215] As shown in Figures 32 and 33, in some embodiments, two buckles 9212 may be provided, and the two buckles 9212 may be arranged laterally at a distance. The two buckles 9212 may be arranged corresponding to the two side portions 912 respectively, and the two buckles 9212 may be snapped onto the two side portions 912 respectively.

[0216] As shown in Figures 28 and 29, in some embodiments, the bottom surface of the water collection tank 100 is provided with a downwardly recessed collecting groove 127. The heat sink 93 can be arranged vertically opposite to the collecting groove 127. The lower end of the heat sink 93 can extend into the collecting groove 127. Thus, the collecting groove 127 can be lower than the bottom surface of the water collection tank 100, allowing water in the water collection tank 100 to be preferentially stored in the collecting groove 127, resulting in a relatively higher water level in the collecting groove 127. This increases the contact area between the lower end of the heat sink 93 and the water, improving the heat dissipation efficiency of the heat sink 93, and consequently improving the heat dissipation performance of the reactor 91.

[0217] As shown in Figures 28 and 29, in some embodiments, the collecting tank 127 can be located on the bottom surface of the second collecting tank 125. In this case, the reactor assembly 9 can be located above the second collecting tank 125. With the connecting channel 122 connecting the first collecting tank 124 and the second collecting tank 125, water in the first collecting tank 124 can also enter the second collecting tank 125 and then the collecting tank 127, effectively raising the water level at the collecting tank 127.

[0218] It should be noted that in some other embodiments, the collecting tank 127 may also be located on the bottom surface of the first collecting tank 124, in which case the reactor assembly 9 may be located above the first collecting tank 124. Alternatively, the collecting tank 127 may also be located on other collecting tanks 100.

[0219] As shown in Figures 26, 32, and 33, in some embodiments, the mounting base 92 may include a mounting base plate 922. The mounting base plate 922 may extend from the lower end of the mounting side plate 921 toward the bottom of the reactor 91. The mounting base plate 922 may be mounted above the chassis 12. The reactor 91 may be fixed above the mounting base plate 922. The mounting base plate 922 may support the bottom of the reactor 91, allowing the reactor 91 to be stably fixed on the mounting base 92.

[0220] It should be noted that in some other embodiments, the heat sink 93 may also extend downward from the mounting base 922. In this case, the bottom of the reactor 91 can be attached to the top surface of the mounting base 922. Thus, the heat from the reactor 91 can be transferred to the heat sink 93 through the mounting base 922, thereby improving the heat dissipation efficiency of the reactor 91 and enhancing its overall heat dissipation performance through the cooperation of the mounting base 922 and the heat sink 93.

[0221] As shown in Figures 29, 32, and 33, in some embodiments, the mounting base 922 is provided with a first heat dissipation vent 9221. Air below the bottom of the mounting base 92 can enter the area above the mounting base 922 through the first heat dissipation vent 9221, flow through the reactor 91, and dissipate heat from the reactor 91 using airflow.

[0222] As shown in Figures 29, 32, and 33, in some embodiments, the outlet 1261 may be located below the mounting base 922. The first heat dissipation vent 9221 may communicate with the outlet 1261. Thus, air from outside the housing 1 can enter the water collection tank 100 through the outlet 1261 on the chassis 12, and then enter the mounting base 92 through the first heat dissipation vent 9221 on the mounting base 922, contacting the reactor 91 to dissipate heat. In this way, fresh air from outside the housing 1 can be used to dissipate heat from the reactor 91 inside the housing 1.

[0223] As shown in Figures 26, 30, and 32, in some embodiments, the reactor assembly 9 may include a protective cover 94. The protective cover 94 may be fitted onto the mounting base 92. The protective cover 94 and the mounting base 92 may be joined to form a reactor box 90. The reactor 91 may be located inside the reactor box 90. Thus, by joining the protective cover 94 and the mounting base 92 to form the reactor box 90, the reactor 91 can be protected inside the reactor box 90.

[0224] As shown in Figures 17, 26, 30, and 32, in some embodiments, the mounting side plate 921 may be provided with a ventilation opening 9213 connecting to the interior of the reactor box 90, and the protective cover 94 may be provided with a second heat dissipation opening 941 connecting to the interior of the reactor box 90. A vent 3521 may be provided on the side wall of the first air duct component 35. The vent 3521 may be arranged opposite to and connected to the ventilation opening 9213. Air from outside the protective cover 94 can enter the interior of the reactor box 90 through the second heat dissipation opening 941 to dissipate heat from the reactor 91, and then be exhausted through the ventilation opening 9213 and the vent 3521. In this way, a stable airflow heat dissipation channel can be formed inside the reactor box 90.

[0225] As shown in Figures 17, 26, 32 and 33, in some embodiments, air outside the reactor box 90 can also enter the reactor box 90 through the first heat dissipation port 9221 on the mounting base plate 922 to dissipate heat from the reactor 91, and then be discharged through the ventilation port 9213 and the vent 3521.

[0226] It should be noted that in some other embodiments, air outside the reactor box 90 can also enter the reactor box 90 through the vent 3521 and the ventilation port 9213 to dissipate heat from the reactor 91, and then be discharged through the first heat dissipation port 9221 or the second heat dissipation port 941.

[0227] As shown in Figures 17, 26, and 31, in some embodiments, a ventilation grille 942 may be provided on the side wall of the protective cover 94. The ventilation grille 942 can connect to the interior of the reactor box 90. Air from outside the reactor box 90 can also enter the interior of the reactor box 90 through the ventilation grille 942 to dissipate heat from the reactor 91, and then be exhausted through the vent 9213 and the air outlet 3521.

[0228] As shown in Figures 31 and 33, in some embodiments, the protective cover 94 may have a hook portion 943 on the side near the vent 9213. The hook portion 943 can extend into the vent 9213 and engage with the side edge of the vent 9213.

[0229] The air conditioner of this disclosure embodiment can also be used to solve the heat dissipation problem of electronic control components such as the electronic control box, so as to improve the heat dissipation effect of the electronic control components. In the relevant air conditioner, the electronic control components include an electronic control box and an electronic control board. The electronic control board is disposed in the electronic control box, which has a heat dissipation inlet and a heat dissipation outlet. Air can flow into the electronic control box through the heat dissipation inlet and flow out from the heat dissipation outlet after flowing through the electronic control board, so as to carry away the heat of the electronic control board, thereby cooling the electronic control board. However, due to the unreasonable structural design in the relevant technology, the effect of generating airflow in the electronic control box is poor. The airflow rate in the electronic control box is slow or the airflow volume is small, which cannot effectively remove the heat of the electronic control board, resulting in poor heat dissipation and cooling effect.

[0230] To address the aforementioned problems, as shown in Figures 34 and 35, an air conditioner according to some embodiments of this disclosure may include a housing 1. The housing 1 is provided with an indoor air inlet 111 and an indoor air outlet 112, through which indoor air can enter the housing 1 through the indoor air inlet 111 and flow back into the room through the indoor air outlet 112.

[0231] As shown in Figure 36, in some embodiments, the housing 1 may also be provided with an outdoor air inlet 114 and an outdoor air outlet 115. Outdoor air can enter the housing 1 through the outdoor air inlet 114 and flow back to the outside through the outdoor air outlet 115.

[0232] As shown in Figure 36, in some embodiments, the air conditioner may include an indoor heat exchanger 23. The indoor heat exchanger 23 is disposed inside the casing 1. Indoor air enters the casing 1 through the indoor air inlet 111 and can exchange heat with the indoor heat exchanger 23.

[0233] As shown in Figure 36, in some embodiments, the air conditioner may include an indoor fan assembly. The indoor fan assembly is disposed inside the housing 1. The indoor fan assembly drives indoor air to enter the housing 1 from the indoor air inlet 111, and after exchanging heat with the indoor heat exchanger 23, the indoor air flows back into the room through the indoor air outlet 112. The indoor fan assembly can guide the flow of indoor air to accelerate the flow rate of indoor air from the indoor air inlet 111 into the housing 1 and from the indoor air outlet 112 back into the room, thereby improving the heat exchange efficiency between the indoor air and the indoor heat exchanger 23.

[0234] As shown in Figures 36 and 37, in some embodiments, the air conditioner may include an outdoor heat exchanger 22, which is located inside the casing 1. Outdoor air enters the casing 1 through the outdoor air inlet 114 and exchanges heat with the refrigerant in the outdoor heat exchanger 22. For example, when the air conditioner is cooling the room, the high-temperature refrigerant flowing from the compressor can first flow to the outdoor heat exchanger 22 and release heat to the outdoor air through it. After the refrigerant temperature decreases, it flows to the indoor heat exchanger 23 to absorb heat from the indoor air, thereby lowering the indoor air temperature and thus cooling the room. When the air conditioner is heating the room, the high-temperature refrigerant flowing from the compressor can first flow to the indoor heat exchanger 23 and release heat to the indoor air through it, thereby raising the indoor temperature and thus heating the room. Then, after the refrigerant temperature decreases, it flows to the outdoor heat exchanger 22 and absorbs heat from the outdoor air through it. After the refrigerant temperature rises, it flows back to the compressor, completing the heating cycle.

[0235] As shown in Figure 37, in some embodiments, the air conditioner may include an air duct assembly 300. The air duct assembly 300 is disposed inside the housing 1 and is connected to the outdoor air inlet 114 and the outdoor air outlet 115, respectively. The air duct assembly 300 can guide outdoor air to make the flow of outdoor air into the housing 1 more orderly.

[0236] As shown in Figure 37, in some embodiments, the air conditioner may include an outdoor fan 34. The outdoor fan 34 is disposed within the air duct assembly 300. The outdoor fan 34 drives outdoor air into the casing 1 from the outdoor air inlet 114, and after exchanging heat with the outdoor heat exchanger 22, the outdoor air flows back to the outside through the outdoor air outlet 115. That is, the outdoor fan 34 can guide the flow of outdoor air to accelerate the flow rate of outdoor air from the outdoor air inlet 114 into the casing 1 and back to the outside through the outdoor air outlet 115, thereby improving the heat exchange efficiency between the outdoor air and the outdoor heat exchanger 22. The outdoor fan 34 may be a centrifugal fan.

[0237] As shown in Figures 36 and 37, in some embodiments, the air conditioner may include an electronic control component 800. The electronic control component 800 may be disposed within the housing 1 and located below the outdoor fan 34. The electronic control component 800 may be electrically connected to the compressor, the indoor fan assembly, and the outdoor fan 34.

[0238] As shown in Figures 40 and 41, in some embodiments, the electronic control component 800 may include an electronic control box 8. The electronic control box 8 is provided with a heat dissipation inlet 813 and a heat dissipation outlet 812. In this way, air can flow into the electronic control box 8 through the heat dissipation inlet 813 and flow out of the electronic control box 8 through the heat dissipation outlet 812. The airflow flowing through the inside of the electronic control box 8 can carry away the heat inside the electronic control box 8, thereby reducing the internal temperature of the electronic control box 8 and preventing the temperature of the electronic control component 800 from becoming too high.

[0239] As shown in Figures 40 and 41, in some embodiments, the electronic control component 800 may further include an electronic control board 820. The electronic control board 820 is disposed within the electronic control box 8. The electronic control box 8 provides an installation location for the electronic control board 820 and protects the electronic control board 820. When airflow passes through the interior of the electronic control box 8, it can carry away the heat of the electronic control board 820, thereby preventing the electronic control board 820 from overheating and ensuring that the electronic control board 820 can operate normally.

[0240] As shown in Figures 37 and 38, in some embodiments, the outdoor heat exchanger 22 can be located on one side of the air duct assembly 300, and a negative pressure space 340 is formed between the outdoor heat exchanger 22 and the air duct assembly 300. The heat dissipation outlet 812 can communicate with the negative pressure space 340. Specifically, when the air conditioner is running, the outdoor fan 34 rotates, which generates negative pressure in the negative pressure space 340, that is, suction is generated in the negative pressure space 340. This suction can draw airflow from the outdoor heat exchanger 22 and the electrical control box 8 into the air duct assembly 300 and exhaust it outdoors. In other words, the negative pressure in the negative pressure space 340 can be used to generate forced convection in the electrical control box 8, so that more air can flow into the electrical control box 8 from the heat dissipation inlet 813 and then flow to the negative pressure space 340 from the heat dissipation outlet 812. The airflow through the electrical control box 8 can be greater, and the flowing air can carry away the heat of the electrical control board 820, preventing the temperature of the electrical control component 800 from getting too high, and improving the heat dissipation effect of the electrical control component 800.

[0241] Moreover, the heat dissipation outlet 812 can be directly connected to the negative pressure space 340. The heat dissipation outlet 812 will not be blocked by other components, so the suction force generated in the negative pressure space 340 can be used more effectively to generate forced convection in the electronic control box 8, which further increases the airflow of the electronic control box 8. The flowing airflow has a better heat dissipation effect on the electronic control component 800.

[0242] In addition, by utilizing the airflow to remove the heat from the electronic control component 800, the heat dissipation effect of the electronic control component 800 is better. Therefore, it is not necessary to set too many heat dissipation holes on the electronic control box 8. This not only makes it easier to process the electronic control box 8, but also improves the sealing performance of the electronic control box 8, and provides better fireproof and rainproof effects. Even if the electronic control component 800 catches fire, it can effectively reduce the chance of fire spreading.

[0243] Thus, the air conditioner according to the present disclosure embodiment can use the negative pressure formed by the negative pressure space 340 to accelerate the air flow rate in the electronic control box 8, thereby forming forced convection in the electronic control box 8, so as to use the airflow to dissipate heat and cool down the electronic control component 800, which is beneficial to improving the heat dissipation effect of the electronic control component 800.

[0244] In some embodiments of this disclosure, as shown in FIG36, the air duct assembly 300 may include a first air duct component 35. The lower side of the first air duct component 35 may be mounted on the housing 1. That is, the first air duct component 35 is disposed inside the housing 1 and adjacent to the lower part of the housing 1.

[0245] In some embodiments, as shown in FIG36, the air duct assembly 300 may include a second air duct component 31. The second air duct component 31 is disposed on one side of the first air duct component 35. An electronic control component 800 is disposed on one side of the first air duct component 35 and located below the second air duct component 31. For example, the second air duct component 31 may be disposed on the side of the first air duct component 35 facing away from the outdoor heat exchanger 22, and the electronic control component 800 and the second air duct component 31 may be located on the same side of the first air duct component 35. After the second air duct component 31 and the first air duct component 35 are connected, a cavity can be formed for mounting the outdoor fan 34.

[0246] In some embodiments, as shown in Figures 36 and 38, the first air duct component 35 is provided with a connecting hole 3501. The heat dissipation outlet 812 is connected to the negative pressure space 340 through the connecting hole 3501. In this way, the first air duct component 35 does not isolate the negative pressure space 340 from the heat dissipation outlet 812, so that the suction force generated in the negative pressure space 340 can act on the electrical control box 8 through the connecting hole 3501 and the heat dissipation outlet 812, thereby generating forced convection inside the electrical control box 8, so as to use the flowing airflow to remove the heat of the electrical control board 820, thereby improving the heat dissipation efficiency of the electrical control component 800.

[0247] In some embodiments of this disclosure, as shown in Figures 41 and 42, the control box 8 is provided with an air outlet 811, which protrudes from the side of the control box 8 facing the first air duct component 35, and a heat dissipation outlet 812 is constructed within the air outlet 811. The air outlet 811 extends into the connecting hole 3501. The air outlet 811 can extend circumferentially along the connecting hole 3501, and its outer contour can be adapted to the outer contour of the connecting hole 3501. This facilitates the insertion of the air outlet 811 into the connecting hole 3501, thereby enabling the relative positioning of the control box 8 and the first air duct component 35 through the cooperation of the air outlet 811 and the connecting hole 3501.

[0248] In some embodiments, as shown in FIG38, the outer wall of the air outlet 811 can be fitted with the inner wall of the connecting hole 3501, which helps to improve the sealing performance between the heat dissipation outlet 812 and the connecting hole 3501, preventing air leakage. This allows for more effective use of the negative pressure in the negative pressure space 340 to generate suction within the electrical control box 8, thereby creating airflow within the electrical control box 8 and improving the heat dissipation effect on the electrical control component 800. Of course, to facilitate the assembly between the electrical control box 8 and the first air duct component 35, a clearance fit can also be used between the outer wall of the air outlet 811 and the inner wall of the connecting hole 3501.

[0249] In some embodiments of this disclosure, as shown in Figures 36, 38, and 39, the air conditioner may further include a first drip tray 5. The first drip tray 5 may be disposed on the lower side of the outdoor heat exchanger 22. A guide rib 3502 is provided on the side of the first air duct component 35 facing the outdoor heat exchanger 22. The guide rib 3502 extends circumferentially along the connecting hole 3501, and the guide rib 3502 and the first drip tray 5 together define an air guiding channel 3503. The air guiding channel 3503 communicates with both the connecting hole 3501 and the negative pressure space 340. By providing the guide rib 3502, the structural strength of the first air duct component 35 around the connecting hole 3501 can be improved. Moreover, the air guide ribs 3502 and the first water receiving tray 5 define the air guide channel 3503, which has a simple structure and can guide the air through the air guide channel 3503 so that the airflow in the electrical control box 8 can flow to the negative pressure space 340.

[0250] Specifically, when the air conditioner is working, the outdoor fan 34 operates, and a negative pressure is generated in the negative pressure space 340. Under the action of the negative pressure, airflow is forced to be generated in the control box 8. That is, air can flow into the control box 8 from the heat dissipation inlet 813. After the air flows through the control board 820 and carries away the heat of the control board 820, it flows into the negative pressure space 340 through the heat dissipation outlet 812, the connecting hole 3501 and the air guide channel 3503 in sequence. Finally, it can be driven by the outdoor fan 34 to be discharged outdoors, thereby improving the heat dissipation efficiency of the control board 820.

[0251] In other embodiments, the air conditioner may further include an air duct (not shown in the figures), which is connected to the side of the first air duct 35 facing the outdoor heat exchanger 22, and the connecting hole 3501 is connected to the negative pressure space 340 through the air duct. That is, the connecting hole 3501 and the negative pressure space 340 can also be connected through the air duct. Specifically, one end of the air duct is connected to the connecting hole 3501, and the other end of the air duct is connected to the negative pressure space 340. In this way, the connecting hole 3501 and the negative pressure space 340 can be connected by the air duct, and the sealing and air guiding effects can be better, so that the airflow in the electrical control box 8 can flow smoothly into the negative pressure space 340, which is beneficial to improving the heat dissipation efficiency of the electrical control component 800.

[0252] As shown in Figures 40 and 41, in some embodiments, the heat dissipation inlet 813 is adjacent to the lower side of the control box 8, and the heat dissipation outlet 812 is adjacent to the upper side of the control box 8. Thus, air can flow into the control box 8 through the lower heat dissipation inlet 813 and then flow out of the control box 8 through the upper heat dissipation outlet 812. This allows the air to maintain a "bottom in, top out" flow direction, enabling the airflow within the control box 8 to better pass through the control board 820. The contact area between the airflow and the control board 820 can be larger, allowing the airflow to more effectively remove heat from the control board 820, thereby improving the heat dissipation effect on the control board 820.

[0253] As shown in Figures 36 and 37, in some embodiments, the first air duct component 35 is provided with a ventilation grille 3504. The first air duct component 35 and the housing 1 define a heat dissipation air intake channel 160. The ventilation grille 3504 is connected to the outdoor air intake 114 through the heat dissipation air intake channel 160, and the heat dissipation inlet 813 is also connected to the ventilation grille 3504. That is, the ventilation grille 3504 is connected to both the heat dissipation inlet 813 and the outdoor air intake 114. In this way, the first air duct component 35 will not completely cover the heat dissipation inlet 813, and outdoor air can flow to the heat dissipation inlet 813 through the heat dissipation air intake channel 160 and the ventilation grille 3504, so that outdoor air can flow into the electrical control box 8, and thus the outdoor air can be used to dissipate heat and cool the electrical control board 820 inside the electrical control box 8.

[0254] Specifically, outdoor air can enter the electrical control box 8 sequentially through the outdoor air inlet 114, the heat dissipation air inlet channel 160, the ventilation grille 3504, and the heat dissipation inlet 813. Then, the outdoor air can flow upward in the vertical direction and exit the electrical control box 8 through the heat dissipation outlet 812. Finally, it can flow to the negative pressure space 340 through the air guide channel 3503 and be discharged outdoors under the drive of the outdoor fan 34.

[0255] As shown in Figures 36, 40, and 41, in some embodiments, the electronic control component 800 may further include a heat sink 830. The heat sink 830 is connected to the electronic control board 820 and protrudes from the heat dissipation inlet 813 and is adjacent to the ventilation grille 3504. In this way, the heat sink 830 can be close to the ventilation grille 3504, and when outdoor air flows through the ventilation grille 3504 to the heat dissipation inlet 813, it can be ensured that part of the airflow can flow through the heat sink 830. This allows the airflow to carry away the heat on the heat sink 830, thereby improving the heat dissipation efficiency of the heat sink 830 on the electronic control board 820.

[0256] As shown in Figures 40 and 41, in some embodiments, the heat dissipation inlet 813 may include a first inlet 814. The first inlet 814 is located on the side of the electrical control box 8 facing the first air duct component 35. The first inlet 814 is adjacent to the ventilation grille 3504, and the radiator 830 is exposed from the first inlet 814. That is, the first inlet 814 can communicate with the outdoor air inlet 114 through the ventilation grille 3504, so that outdoor air can flow into the electrical control box 8 through the first inlet 814 to dissipate heat and cool the electrical control component 800.

[0257] As shown in Figures 40 and 41, in some embodiments, the heat dissipation inlet 813 may include a second inlet 815. The second inlet 815 is located on one side of the electrical control box 8 in the width direction. The housing 1 is provided with an air intake grille 150. The second inlet 815 is adjacent to the air intake grille 150. For example, the first inlet 814 and the second inlet 815 may be located on adjacent sides of the electrical control box 8. In this way, indoor air can flow into the electrical control box 8 sequentially through the air intake grille 150 and the second inlet 815 to dissipate heat and cool the electrical control component 800. Therefore, by providing the first inlet 814 and the second inlet 815, the air intake volume of the electrical control box 8 can be increased, thereby generating more airflow within the electrical control box 8, which is beneficial to improving the heat dissipation efficiency of the airflow on the electrical control component 800, resulting in better heat dissipation.

[0258] As shown in Figures 36 and 37, in some embodiments, the air duct assembly 300 has an air duct inlet 301 on the side facing the outdoor heat exchanger 22, and the heat dissipation outlet 812 is connected to the air duct inlet 301. Thus, when the air conditioner is running, the outdoor fan 34 rotates, generating negative pressure at the air duct inlet 301, i.e., generating suction at the air duct inlet 301. This suction can draw airflow from the outdoor heat exchanger 22 and the electrical control box 8 into the air duct assembly 300 and exhaust it outdoors. In other words, the negative pressure generated at the air duct inlet 301 can create forced convection within the electrical control box 8, allowing more air to flow into the electrical control box 8 from the heat dissipation inlet 813 and then from the heat dissipation outlet 812 to the air duct inlet 301. This results in a larger airflow rate through the electrical control box 8, which can then carry away heat from the electrical control board 820, preventing the electrical control component 800 from overheating and improving the heat dissipation effect of the electrical control component 800.

[0259] Moreover, the heat dissipation outlet 812 can be directly connected to the air inlet 301 of the air duct, and the heat dissipation outlet 812 will not be blocked by other components. This allows for more effective use of the suction force generated at the air inlet 301 of the air duct to create forced convection within the control box 8, further increasing the airflow of the control box 8. The flowing airflow provides better heat dissipation for the control components 800.

[0260] In addition, this design utilizes airflow to remove heat from the electronic control component 800, resulting in better heat dissipation. This eliminates the need for excessive ventilation holes on the electronic control box 8, making it easier to process and improving its sealing performance. It also provides better fire and rain protection, and even if the electronic control component 800 catches fire, it can effectively reduce the chance of fire spread.

[0261] Thus, the air conditioner according to the present disclosure embodiment can generate negative pressure at the air inlet 301 of the air duct, and can use the negative pressure at the air inlet 301 of the air duct to accelerate the air flow rate in the control box 8, thereby forming forced convection in the control box 8, so as to use the airflow to dissipate heat and cool down the control component 800, which is beneficial to improving the heat dissipation effect of the control component 800.

[0262] Those skilled in the art will understand that the scope of this disclosure is not limited to the specific embodiments described above, and that modifications and substitutions can be made to certain elements of the embodiments without departing from the spirit of this disclosure. The scope of this disclosure is limited by the appended claims.
