Description

Technical Field

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

[0002] The air conditioner in the related technology includes a casing, a heat exchanger and a fan assembly. The fan assembly can drive indoor air to flow into the casing through the air inlet on the casing, and after exchanging heat with the heat exchanger, flow into the room through the air outlet to heat or cool the room.

[0003] Furthermore, the air conditioner also includes a fixed bracket, a drive motor, and an air guide assembly. The drive motor is fixed to the fixed bracket, and the air guide assembly is connected to the drive motor. In this way, the drive motor can drive the air guide assembly to rotate, so as to adjust the airflow direction in the circumferential direction of the air outlet.

[0004] However, due to the unreasonable setting of the fixing structure of the air guide component in the relevant technology, the fixing structure of the air guide component has poor stability and is affected by manufacturing errors and assembly errors. When the drive motor drives the air guide component to rotate, the air guide component is prone to interference and friction with other parts, which will generate noise or vibration and result in a poor user experience. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to provide an air conditioner that, by placing the air guide assembly between a fixed plate and a panel frame, limits the axial movement of the air guide assembly on both sides. This improves the stability of the air guide assembly, makes its operation more stable, and avoids positional interference between the air guide assembly and other components, preventing noise or vibration and providing a better user experience.

[0006] To achieve the above objectives, an air conditioner is proposed according to an embodiment of the present invention. The air conditioner includes: a housing, the housing being suitable for placement on the ground and having an air inlet and an air outlet, a panel frame being provided on the front side of the housing, the air outlet being constructed on the panel frame, and the panel frame having an air outlet grille at the air outlet; a heat exchanger, the heat exchanger being disposed within the housing; a fan assembly, the fan assembly being disposed within the housing, the fan assembly driving indoor air to enter the housing from the air inlet, and the indoor air flowing back into the room from the air outlet after exchanging heat with the heat exchanger; the air conditioner further includes: a fixed bracket, the fixed bracket... A fixed bracket is disposed inside the housing and located at the air outlet, and the fixed bracket is connected to the panel frame; a drive motor is mounted on the fixed bracket and located at the center of the air outlet; an air guide assembly is rotatably disposed at the air outlet and driven by the drive motor, the drive motor drives the air guide assembly to rotate, so as to adjust the air outlet direction of the airflow in the circumferential direction of the air outlet; wherein, the air guide assembly is disposed between the fixed bracket and the air outlet grille, one side of the air guide assembly is driven by the drive motor, and the other side of the air guide assembly is rotatably connected to the air outlet grille.

[0007] The above technical solution has the following advantages or beneficial effects: The drive motor is located at the center of the air guide assembly, allowing the drive motor to connect to the center of the air guide assembly. Under the drive of the drive motor, the air guide assembly can rotate around its central axis. That is, the positioning point and rotation drive point of the air guide assembly are both at the center, which facilitates the separation of the circumferential edge of the air guide assembly from other components, avoiding interference between the air guide assembly and adjacent components. This also prevents noise or vibration caused by friction during the rotation of the air guide assembly, making the rotation of the air guide assembly more stable. Moreover, by placing the air guide assembly between the fixed bracket and the air outlet grille, the fixed bracket and the air outlet grille can jointly limit and fix the air guide assembly from both sides of the axial direction. During the rotation of the air guide assembly driven by the drive motor, positional displacement along the axial direction can be avoided, achieving "floating" rotation of the air guide assembly. This not only improves the air guiding effect of the air guide assembly but also enhances its rotational stability, making it less prone to noise or vibration caused by friction with other components.

[0008] According to some embodiments of the present invention, the air guide assembly is spaced apart from the fixed bracket and the panel frame along both the radial and axial directions of the air outlet.

[0009] The above technical solution has the following advantages or beneficial effects: multiple parts of the air guide component are spaced apart from the fixed bracket and the panel frame, which can avoid positional interference between the air guide component and the fixed bracket or the panel frame, and can realize the "floating" rotation of the air guide component. This can more effectively avoid noise or vibration caused by friction between the air guide component and the fixed bracket or the panel frame, the rotation of the air guide component can be more stable, the air guiding effect is better, and the user experience is better.

[0010] According to some embodiments of the present invention, the air guide assembly has a first rotating part on the side facing the fixed bracket, and the first rotating part is connected to the motor shaft of the drive motor; and the air guide assembly has a second rotating part on the side facing the air outlet grille, and the second rotating part is rotatably connected to the air outlet grille.

[0011] The above technical solution has the following advantages or beneficial effects: In this way, one side of the air guide assembly can be connected and fixed to the motor shaft through the first rotating part, while the other side of the air guide assembly can be connected to the air outlet grille through the second rotating part, so as to fix the air guide assembly from the center of the two sides of the axial direction of the air guide assembly, and make the air guide assembly rotate around the axis where its center is located.

[0013] The above technical solution has the following advantages or beneficial effects: the frictional resistance between the first rotating part and the fixed bracket can be reduced by the first bearing assembly, so as to realize the rotation of the air guide assembly relative to the fixed bracket; and the frictional resistance between the second rotating part and the air outlet grille can be reduced by the second bearing assembly, so that the air guide assembly can rotate more easily relative to the air outlet grille, the rotation of the air guide assembly can be more stable, and the air guiding effect is better.

[0014] According to some embodiments of the present invention, the first rotating part is provided with a limiting boss, the limiting boss protruding from the outer peripheral surface of the first rotating part, and the limiting boss stopping on the side of the first bearing assembly facing the air outlet grille; and / or, the air conditioner further includes a limiting connector, the limiting connector being detachably connected to one end of the first rotating part adjacent to the drive motor, and the limiting connector stopping on the side of the first bearing assembly facing away from the air outlet grille.

[0015] The above technical solution has the following advantages or beneficial effects: Thus, the limiting boss and the limiting connector can jointly limit the axial direction of the air guide assembly, so that the air guide assembly can be spaced apart from the air outlet grille and the fixed bracket along the axial direction, thereby realizing the "floating" rotation of the air guide assembly, avoiding interference and friction between the air guide assembly and the air outlet grille or the fixed bracket, so as to avoid noise or vibration generated by friction when the air guide assembly rotates.

[0016] According to some embodiments of the present invention, the second bearing assembly further includes: a buffer member, wherein the air outlet grille is provided with a mounting groove and the buffer member is disposed in the mounting groove; and a second bearing, which is fixed to the buffer member and the second rotating part is connected to the second bearing.

[0017] The above technical solution has the following advantages or beneficial effects: the buffer can be constructed with a limiting groove, and the second bearing can be fixed in the limiting groove. By adding the buffer, when the air guide assembly rotates, the buffer can absorb the vibration generated when the air guide assembly rotates, thereby preventing the vibration of the air guide assembly from being transmitted to the air outlet grille, which helps to reduce the noise of the air conditioner and improve the user experience.

[0018] According to some embodiments of the present invention, the air guiding assembly includes: a frame, at least one of the first rotating part and the second rotating part being constructed on the frame; and a plurality of air guiding plates, the plurality of air guiding plates being rotatably connected to the frame and arranged along the radial direction of the frame.

Furthermore, by providing a guide plate, the angle of the guide plate relative to the frame can be adjusted when the air guide assembly rotates. By adjusting the direction of the guide plate, the air guiding effect of the air guide assembly can be further adjusted, thereby allowing for better airflow guidance using the air guide assembly.

[0020] According to some embodiments of the present invention, the air guide assembly further includes: a transmission gear, wherein the frame is provided with a mounting cavity and the inner wall of the mounting cavity is provided with meshing teeth, the transmission gear is disposed in the mounting cavity and meshes with the meshing teeth; a cover plate, the cover plate is connected to the frame and covers part of the mounting cavity, and a portion of the transmission gear extends out from the cover plate and is connected to the motor shaft for transmission.

[0021] The above technical solution has the following advantages or beneficial effects: by adding a transmission gear, the drive motor can drive the frame to rotate through the transmission gear, thereby driving the air guide assembly to rotate. This eliminates the need to directly construct the first rotating part on the frame, which helps to simplify the structure of the frame and facilitates the processing of the frame.

[0022] According to some embodiments of the present invention, the transmission gear has a transmission shaft on the side facing the drive motor, and the cover plate has an axial fitting portion, the transmission shaft passes through the axial fitting portion, and the transmission shaft and the axial fitting portion together define the first rotating portion; or the transmission gear has a transmission shaft on the side facing the drive motor, the transmission shaft extends from the cover plate and is configured as the first rotating portion.

[0031] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0032] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0033] The air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings. The air conditioner according to the present invention can be a cabinet-type air conditioner.

[0034] like Figures 1-10 As shown, the air conditioner according to an embodiment of the present invention may include a housing, which is suitable for placement on the ground and has an air inlet and an air outlet 110. A panel frame 100 is provided on the front side of the housing, the air outlet 110 is constructed on the panel frame 100, and the panel frame 100 has an air outlet grille 120 at the air outlet 110. In this way, indoor air can flow into the housing through the air inlet on the housing and into the room through the air outlet 110 on the panel frame 100.

[0035] An air conditioner may include a heat exchanger located inside the casing. Air entering the casing can exchange heat with the heat exchanger to form a heat exchange airflow. The heat-exchanged airflow can flow into the room through the air outlet 110 to heat or cool the room.

[0036] The air conditioner may include a fan assembly, which is located inside the housing. The fan assembly drives indoor air to enter the housing from the air inlet, and the indoor air flows back into the room from the air outlet 110 after exchanging heat with the heat exchanger.

[0037] The fan assembly can draw indoor air into the casing to increase the airflow velocity at the air inlet and outlet 110. This allows more airflow to exchange heat with the heat exchanger, thereby improving the heat exchange efficiency of the air conditioner. This, in turn, enables better cooling or heating of the room and ultimately improves the energy efficiency of the air conditioner.

[0038] The air conditioner may also include a mounting bracket 200, which is located inside the housing and at the air outlet 110, and is connected to the panel frame 100.

[0039] For example, the fixed bracket 200 and the panel frame 100 can be connected by bolts and / or snap-fit, so that the fixed bracket 200 can be detachably connected to the panel frame 100 and the fixation is relatively stable, so as to ensure the stability of the connection between the fixed bracket 200 and the panel frame 100.

[0040] The air conditioner may also include a drive motor 400, which is mounted on a fixed bracket 200 and located at the center of an air outlet 110. The air outlet 110 may be circular, and the drive motor 400 may correspond to the center of the air outlet 110.

[0041] The air conditioner may also include an air guide assembly 300, which is rotatably disposed at the air outlet 110 and is connected to a drive motor 400. The drive motor 400 drives the air guide assembly 300 to rotate, thereby adjusting the air outlet direction in the circumferential direction of the airflow at the air outlet 110.

[0042] The drive motor 400 is located at the center of the air guide assembly 300. This allows the drive motor 400 to connect to the center of the air guide assembly 300. Driven by the drive motor 400, the air guide assembly 300 can rotate around its central axis. That is, the positioning point and the rotation drive point of the air guide assembly 300 are both at the center. This facilitates the separation of the circumferential edge of the air guide assembly 300 from other components, thus avoiding interference between the air guide assembly 300 and adjacent components. This also prevents the air guide assembly 300 from generating noise or vibration due to friction during rotation, making the rotation of the air guide assembly 300 more stable.

[0043] The air guide assembly 300 is located between the fixed bracket 200 and the air outlet grille 120. One side of the air guide assembly 300 is connected to the drive motor 400, and the other side of the air guide assembly 300 is rotatably connected to the air outlet grille 120.

[0044] By placing the air guide assembly 300 between the fixed bracket 200 and the air outlet grille 120, the fixed bracket 200 and the air outlet grille 120 can jointly limit and fix the air guide assembly 300 from both sides of the axial direction. This improves the stability of the air guide assembly 300 and prevents it from shifting along the axial direction during the rotation driven by the drive motor 400. This makes the rotation of the air guide assembly 300 more stable and less likely to interfere with the position of adjacent components. As a result, the air guide assembly 300 can rotate in a "floating" manner. This not only improves the air guiding effect of the air guide assembly 300 but also enhances its rotational stability. The air guide assembly 300 is less likely to rub against other components, generating noise or vibration, resulting in a better user experience.

[0045] Thus, the air conditioner according to this utility model embodiment limits the axial sides of the air guide assembly 300 by placing the air guide assembly 300 between the fixing plate and the panel frame 100. This improves the fixing stability of the air guide assembly 300, makes the operation of the air guide assembly 300 more stable, and avoids positional interference between the air guide assembly 300 and other components, thus avoiding noise or vibration and providing a better user experience.

[0046] In some specific embodiments of this utility model, such as Figure 2 and Figure 3 As shown, along the radial and axial directions of the air outlet 110, the air guide assembly 300 is spaced apart from the fixed bracket 200 and the panel frame 100.

[0047] That is, multiple parts of the air guide component 300 are spaced apart from the fixed bracket 200 and the panel frame 100. This avoids positional interference between the air guide component 300 and the fixed bracket 200 or the panel frame 100, thereby enabling the air guide component 300 to rotate in a "floating" manner. This more effectively avoids noise or vibration caused by friction between the air guide component 300 and the fixed bracket 200 or the panel frame. The rotation of the air guide component 300 is more stable, the air guiding effect is better, and the user experience is better.

[0048] In some specific embodiments of this utility model, such as Figure 3 As shown, the air guide assembly 300 has a first rotating part 313 on the side facing the fixed bracket 200, and the first rotating part 313 is connected to the motor shaft 410 of the drive motor 400.

[0049] The air guide assembly 300 has a second rotating part 316 on the side facing the air outlet grille 120, and the second rotating part 316 is rotatably connected to the air outlet grille 120.

[0050] The first rotating part 313 and the second rotating part 316 are coaxially arranged and can be located at the center of the air guide assembly 300. In this way, one side of the air guide assembly 300 can be connected and fixed to the motor shaft 410 through the first rotating part 313, while the other side of the air guide assembly 300 can be connected to the air outlet grille 120 through the second rotating part 316, so as to fix the air guide assembly 300 from the center of both sides of the axial direction and allow the air guide assembly 300 to rotate around the axis where its center is located.

[0051] In addition, the first rotating part 313 can be directly connected to the motor shaft 410. When the drive motor 400 is running, the motor shaft 410 can directly drive the air guide assembly 300 to rotate through the first rotating part 313. This can reduce the number of parts that are connected to the drive motor 400 and the air guide assembly 300, which is conducive to simplifying the assembly structure, facilitating assembly, and reducing production costs.

[0052] Of course, in some other embodiments, the first rotating part 313 can also be indirectly connected to the motor shaft 410. For example, the motor shaft 410 can be connected to the first rotating part 313 through gears to achieve speed reduction and torque increase output of the drive motor 400. Furthermore, the connection between the air guide assembly 300 and the drive motor 400 can be more flexible so that the air guide assembly 300 can better adapt to the spatial layout constraints within the housing and facilitate assembly.

[0053] Furthermore, such as Figure 3 As shown, the air conditioner may also include a first bearing assembly 510, which is mounted on a fixed bracket 200. A first rotating part 313 passes through the first bearing assembly 510 and is connected to the first bearing assembly 510. That is, the first rotating part 313 and the fixed bracket 200 are rotatably engaged through the first bearing assembly 510.

[0054] The first bearing assembly 510 may include a first bearing 511 and a bearing limiting member 512.

[0055] Specifically, the fixed bracket 200 may be provided with a mounting hole 221, and the first bearing 511 may be fixed in the mounting hole 221. The outer ring of the first bearing 511 may be interference-fitted with the inner wall of the mounting hole 221, and the inner ring of the first bearing 511 may be sleeved on the first rotating part 313 and interference-fitted with the first rotating part 313. With this arrangement, the frictional resistance between the first rotating part 313 and the fixed bracket 200 can be reduced by the first bearing 511, so as to facilitate the rotation of the air guide assembly 300 relative to the fixed bracket 200.

[0056] In addition, the bearing limiting member 512 can be connected to the fixed bracket 200 and stop the first bearing 511 on the side facing the air outlet grille 120. For example, the bearing limiting member 512 can be connected to the fixed bracket 200 by snap-fit ​​or bolt. In this way, the bearing limiting member 512 can limit the side of the first bearing 511 facing the air outlet grille 120 to prevent the first bearing 511 from falling off the fixed bracket 200.

[0057] like Figure 3 and Figure 4 As shown, the air conditioner may further include a second bearing assembly 520, which is mounted on the air outlet grille 120. A second rotating part 316 passes through and is connected to the second bearing assembly 520, meaning that the second rotating part 316 and the air outlet grille 120 are rotatably engaged via the second bearing assembly 520. This reduces the frictional resistance between the second rotating part 316 and the air outlet grille 120, allowing the air guide assembly 300 to rotate more easily relative to the air outlet grille 120. The rotation of the air guide assembly 300 is more stable, resulting in better airflow.

[0058] Specifically, such as Figure 3 and Figure 4 As shown, the second bearing assembly 520 may include a second bearing 521 and a buffer member 522.

[0059] The air outlet grille 120 is provided with a mounting groove 121, the buffer 522 is provided in the mounting groove 121, the second bearing 521 is fixed to the buffer 522, and the second rotating part 316 is connected to the second bearing 521.

[0060] For example, the buffer 522 can be a vibration-damping buffer material such as rubber, but is not limited to this.

[0061] Among them, the buffer 522 can be constructed with a limiting groove 523, and the second bearing 521 can be fixed in the limiting groove 523. By adding the buffer 522, when the air guide assembly 300 rotates, the buffer 522 can absorb the vibration generated when the air guide assembly 300 rotates, thereby preventing the vibration of the air guide assembly 300 from being transmitted to the air outlet grille 120, which helps to reduce the noise of the air conditioner and improve the user experience.

[0062] Furthermore, such as Figure 3 and Figure 9 As shown, the first rotating part 313 is provided with a limiting boss 314, which protrudes from the outer peripheral surface of the first rotating part 313 and stops the first bearing assembly 510 on the side facing the air outlet grille 120.

[0063] The air guide assembly 300 also includes a limiting connector 600, which is detachably connected to one end of the first rotating part 313 adjacent to the drive motor 400, and the limiting connector 600 stops on the side of the first bearing assembly 510 facing away from the air outlet grille 120. The limiting connector 600 and the first rotating part 313 can be connected by snap-fit ​​or bolts.

[0064] Therefore, by stopping the first bearing assembly 510 on the side facing the air outlet grille 120, the air guide assembly 300 can be prevented from moving further into the air conditioner. Similarly, by stopping the first bearing assembly 510 on the side away from the air outlet grille 120, the air guide assembly 300 can be prevented from moving out of the air conditioner. That is, the stopping boss 314 and the stopping connector 600 can jointly limit the axial movement of the air guide assembly 300, allowing it to be axially spaced from the air outlet grille 120 and the fixed bracket 200. This enables the air guide assembly 300 to rotate in a "floating" manner, preventing interference and friction between the air guide assembly 300 and the air outlet grille 120 or the fixed bracket 200, thus avoiding noise or vibration caused by friction during rotation.

[0065] In some specific embodiments of this utility model, such as Figure 6 , Figure 7 and Figure 10 As shown, the air guide assembly 300 may include a frame 310, and at least one of a first rotating part 313 and a second rotating part 316 is configured on the frame 310.

[0066] In other words, one of the first rotating part 313 and the second rotating part 316 can be formed by the frame 310, and the other of the first rotating part 313 and the second rotating part 316 can be formed by connecting other components with the frame 310. This makes the structure of the air guide assembly 300 more flexible and easier to process and assemble.

[0067] Of course, the first rotating part 313 and the second rotating part 316 can both be composed of the frame 310. That is, the first rotating part 313 is constructed on one axial side of the frame 310, and the second rotating part 316 is constructed on the other axial side of the frame 310. This can reduce the number of parts of the air guide assembly 300 and make assembly more convenient.

[0068] The air guide assembly 300 may include a plurality of air guide plates 320, which are rotatably connected to the frame 310 and are arranged along the radial direction of the frame 310.

[0069] Multiple air guide plates 320 can be connected by connecting rods 321, which allows multiple air guide plates 320 to rotate synchronously. Furthermore, by adjusting the direction of the air guide plates 320, the air guiding effect of the air guiding assembly 300 can be further adjusted, thereby enabling the air guiding assembly 300 to better guide the airflow.

[0070] In addition, the air guide plate 320 can be driven by a motor. In this way, when the drive motor 400 drives the air guide assembly 300 to rotate around the center of the air outlet, the motor can also synchronously drive the air guide plate 320 to rotate relative to the frame 310, so as to more flexibly change the flow direction of the air outlet. Thus, the air guide assembly 300 can be used to achieve multi-angle air delivery of the air outlet, resulting in a better user experience.

[0071] In some specific embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the air guide assembly 300 may also include a transmission gear 340, the frame 310 is provided with a mounting cavity 311, and the inner wall of the mounting cavity 311 is provided with meshing teeth 312. The transmission gear 340 is located in the mounting cavity 311 and meshes with the meshing teeth 312.

[0072] The air guide assembly 300 may also include a cover plate 350, which is connected to the frame 310 and has a cover portion mounted in the cavity 311. A portion of the transmission gear 340 extends out from the cover plate 350 and is connected to the motor shaft 410 for transmission.

[0073] By adding a transmission gear 340, the drive motor 400 can drive the frame 310 to rotate through the transmission gear 340, thereby driving the air guide assembly 300 to rotate. This eliminates the need to directly construct the first rotating part 313 on the frame 310, which simplifies the structure of the frame 310, facilitates the processing of the frame 310, and reduces the weight of the frame 310, thereby reducing the overall weight of the air guide assembly 300.

[0074] The frame 310 may be constructed with a positioning groove 317, and a positioning shaft 342 may be provided on the side of the transmission gear 340 facing the air outlet grille 120. The positioning shaft 342 is connected in the positioning groove 317, which can pre-position the assembly of the transmission gear 340 and the frame 310, and facilitates the simplification of the assembly steps.

[0075] Furthermore, such as Figure 9 and Figure 10 As shown, the transmission gear 340 has a transmission shaft 341 on the side facing the drive motor 400, and the cover plate 350 has an axial fitting part 351. The transmission shaft 341 passes through the axial fitting part 351, and the transmission shaft 341 and the axial fitting part 351 together define the first rotating part 313.

[0076] The drive shaft 341 can be connected to the motor shaft 410 for transmission. The axial mating part 351 can extend into and mate with the first bearing assembly 510. Furthermore, the limiting boss 314 can be provided on the outer peripheral surface of the axial mating part 351. Thus, the drive motor 400 can transmit power to the transmission gear 340 through the drive shaft 341, thereby driving the frame 310 to rotate. The axial mating part 351 can mate with the first bearing assembly 510 and axially limit the guide assembly 300.

[0077] In some other specific embodiments of this utility model, a transmission shaft 341 is provided on the side of the transmission gear 340 facing the drive motor 400. The transmission shaft 341 extends from the cover plate 350 and is configured as a first rotating part 313.

[0078] In other words, the first rotating part 313 is defined solely by the drive shaft 341. The drive shaft 341 can be connected to the motor shaft 410 for transmission, and the drive shaft 341 can cooperate with the first bearing assembly 510. The limiting boss 314 can be provided on the outer peripheral surface of the drive shaft 341. This simplifies the structure of the cover plate 350, so that the structure of the air guide assembly 300 can be simpler.

[0079] In some specific embodiments of this utility model, such as Figure 4 As shown, the fixed bracket 200 may include an annular connecting frame 210, which extends annularly along the circumference of the air outlet 110 and is connected to the panel frame 100. For example, the annular connecting frame 210 and the panel frame 100 may be connected by bolts or snap-fit ​​to ensure the stability of the connection between the annular connecting frame 210 and the panel frame 100, and the annular connecting frame 210 will not obstruct the airflow from the air outlet 110.

[0080] Additionally, the fixed bracket 200 may include a connecting arm 220, which extends radially along the fixed bracket 200. The two ends of the connecting arm 220 are respectively connected to the radially opposite sides of the annular connecting frame 210. The center of the connecting arm 220 in the length direction has a mounting hole 221. The drive motor 400 is fixed to the connecting arm 220, and the motor shaft 410 of the drive motor 400 extends into the mounting hole 221. The air guide assembly 300 is connected to the motor shaft 410 in a transmission connection.

[0081] For example, the drive motor 400 can be bolted to the connecting arm 220.

[0082] The first bearing assembly 510 can be fixed in the mounting hole 221. The connecting arm 220 will not interfere with the connection and cooperation between the air guide assembly 300, the drive motor 400, and the first bearing assembly 510, thereby enabling the air guide assembly 300 to be fixed. The connecting arm 220 will not excessively block the air outlet 110, so as to facilitate the air outlet of the air conditioner.

[0083] Other components and operations of the air conditioner according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0084] The air conditioner of this invention performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0085] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0086] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature and humidity of the indoor space.
