Technical Field

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

[0002] Air conditioners in related technologies typically include 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 for transmission. 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 complex assembly structure between the air guide component and the drive motor in the relevant technologies, assembly errors are easily generated, affecting the assembly stability of the air guide component, resulting in poor smoothness of the air guide component's movement, and the assembly is not convenient and has low assembly efficiency.

[0007] The above technical solution has the following advantages or beneficial effects: By placing the bearing assembly between the fixed bracket and the rotating part, the friction between the fixed bracket and the rotating part can be reduced through the bearing assembly. Furthermore, the air guide assembly is directly connected to the motor shaft through the rotating part, which simplifies the transmission connection structure between the air guide assembly and the drive motor. When the motor is running, the motor shaft can directly drive the air guide assembly to rotate through the rotating part.

[0014] According to some embodiments of the present invention, the air conditioner further includes: an air outlet grille, the air outlet grille being disposed on the side of the air guide assembly facing away from the fixed bracket, the air outlet grille being fixed to the air guide assembly, or the air outlet grille being fixed to the panel frame.

[0015] The above technical solution has the following advantages or beneficial effects: the air outlet grille can be fixed to the air guide assembly, so that when the drive motor is running, the air outlet grille can rotate together with the air guide assembly. The air outlet grille can more flexibly guide the airflow, thereby enabling multi-angle air delivery using the air guide assembly, resulting in a better user experience. Alternatively, the air outlet grille can be fixed to the panel frame, and the air outlet grille does not rotate with the air guide assembly, which helps to simplify the structure of the air guide assembly.

[0016] According to some embodiments of the present invention, the air guiding assembly includes: a frame, the frame being drivenly connected to the drive motor, and the air outlet grille being connected to the side of the frame facing away from the fixed bracket; and a plurality of air guiding plates, the plurality of air guiding plates being rotatably connected to the frame, the plurality of air guiding plates being arranged along the radial direction of the frame, and the air guiding plates being disposed on the side of the frame facing away from the air outlet grille.

[0017] The above technical solution has the following advantages or beneficial effects: In this way, the drive motor can drive the frame to rotate, thereby driving the air guide assembly to rotate. Furthermore, multiple air guide plates can be connected by connecting rods, so that multiple air guide plates can rotate synchronously. Moreover, by adjusting the direction of the air guide plates, the air guiding effect of the air guide assembly can be further adjusted, thereby allowing the air guide assembly to better guide the airflow.

[0018] According to some embodiments of the present invention, the rotating part is constructed on the side of the frame facing the fixed bracket, and the frame is connected to the motor shaft via the rotating part.

[0019] The above technical solution has the following advantages or beneficial effects: the rotating part can be completely composed of a frame, and the frame is connected to the drive motor and the air outlet grille respectively.

The axial mating part can also mate with the bearing assembly and axially limit the guide assembly. Alternatively, the rotating part can be limited solely by the transmission shaft, which is connected to the motor shaft and mates with the bearing assembly. The limiting boss can be located on the outer circumferential surface of the transmission shaft, simplifying the cover plate structure and allowing for a simpler structure for the air guide assembly.

[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 1 in this embodiment can be a cabinet-type air conditioner.

[0034] like Figures 1-10As 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 is provided with an air inlet and an air outlet 110. A panel frame 100 is provided on the front side of the housing, and the air outlet 110 is constructed on the panel frame 100. In this way, indoor air can flow into the housing through the air inlet on the housing and flow 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 refrigerant in the heat exchanger. That is, the refrigerant can absorb heat from the air flowing through the heat exchanger, or the refrigerant can release heat to the air flowing through 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. In other words, the fan assembly can drive the airflow. Driven by the fan assembly, more airflow can exchange heat with the heat exchanger to improve the heat exchange efficiency of the air conditioner. As a result, more heat-exchanged airflow can flow into the room through the outlet 110, which can better cool or heat the room, thus improving 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, which allows the fixed bracket 200 to be detachably connected to the panel frame 100, making installation convenient and the connection 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 can be located at the center of the air guide assembly 300. This allows the drive motor 400 to be connected 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 conditioner may also include a bearing assembly 500, which is mounted on a fixed bracket 200. The air guide assembly 300 is provided with a rotating part 320, which is connected to the motor shaft 410 of the drive motor 400. The rotating part 320 passes through the bearing assembly 500 and is connected to the bearing assembly 500.

[0044] In other words, the bearing assembly 500 can be located between the fixed bracket 200 and the rotating part 320. This reduces the friction between the fixed bracket 200 and the rotating part 320. The rotating part 320 is connected to the motor shaft 410. When the drive motor 400 is running, the rotating part 320 can rotate synchronously with the motor shaft 410. In this way, the motor shaft 410 can drive the air guide assembly 300 to rotate through the rotating part 320, so that the air guide assembly 300 can rotate around the axis where its center is located.

[0045] In addition, the air guide assembly 300 is directly connected to the motor shaft 410 through the rotating part 320. This simplifies the transmission connection structure between the air guide assembly 300 and the drive motor 400. When the motor is running, the motor shaft 410 can directly drive the air guide assembly 300 to rotate through the rotating part 320. This not only improves the smoothness of the rotation of the air guide assembly 300 so that the air guide assembly 300 can guide air better, but also reduces the number of parts in the transmission connection between the drive motor 400 and the air guide assembly 300. This simplifies the assembly structure, facilitates assembly, and reduces production costs.

[0046] It should be noted that in some embodiments, the rotating part 320 may also be indirectly connected to the motor shaft 410. For example, the motor shaft 410 may be connected to the rotating part 320 via gears to achieve speed reduction and torque increase output of the drive motor 400.

[0047] The air conditioner may also include a limiting connector 600, which is detachably connected to one end of the rotating part 320 adjacent to the drive motor 400, and the limiting connector 600 stops on the side of the bearing assembly 500 facing away from the panel frame 100.

[0048] The limiting connector 600 and the rotating part 320 can be connected by snap-fit ​​or bolts. This allows the bearing limiting component 520 to stop the bearing assembly 500 on the side facing away from the panel frame 100, preventing the air guide assembly 300 from detaching from the bearing assembly 500 and moving outwards from the air conditioner. This ensures the stability of the relative position between the air guide assembly 300 and the fixed bracket 200, resulting in more stable rotation and better airflow. Furthermore, the drive motor 400 drives the air guide assembly 300 to rotate from its center position. This reduces the likelihood of positional interference between the air guide assembly 300 and adjacent components, allowing for a "floating" rotation. This improves both the airflow effect and rotational stability of the air guide assembly 300, reducing the likelihood of noise or vibration from friction with other components, thus enhancing the user experience.

[0049] Thus, the air conditioner according to this utility model embodiment is directly connected to the drive motor 400 via the rotating part 320, which is simple in structure and easy to assemble. The drive motor 400 drives the air guide assembly 300 to rotate from the center of the air guide assembly 300. The air guide assembly 300 can be separated from other parts, thereby avoiding friction that generates noise or vibration. The air guide assembly 300 rotates more smoothly and has a better air guiding effect, which is conducive to improving the user experience.

[0050] In some specific embodiments of this utility model, such as Figure 3 and Figure 4 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.

[0051] 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 100. The rotation of the air guide component 300 is more stable, the air guiding effect is better, and the user experience is better.

[0052] In some specific embodiments of this utility model, such as Figure 3 and Figure 10 As shown, the rotating part 320 is provided with a limiting boss 321, which protrudes from the outer peripheral surface of the rotating part 320 and stops the bearing assembly 500 on the side facing the panel frame 100.

[0053] The limiting boss 321 can extend into a ring along the circumference of the rotating part 320.

[0054] Therefore, by stopping the bearing assembly 500 on the side facing the air outlet grille 330 by the limiting boss 321, the air guide assembly 300 can be prevented from moving further into the air conditioner. The limiting connector 600 is connected to the air guide assembly 300 and stops the bearing assembly 500 on the side facing away from the air outlet grille 330, thus preventing the air guide assembly 300 from moving out of the air conditioner. That is, the limiting boss 321 and the limiting connector 600 can jointly limit the air guide assembly 300 along the axial direction, so that the air guide assembly 300 can be spaced apart from the panel frame 100 and the fixed bracket 200 along the axial direction. This allows the air guide assembly 300 to rotate in a "floating" manner, avoiding interference and friction between the air guide assembly 300 and the panel frame 100 or the fixed bracket 200. This prevents noise or vibration caused by friction when the air guide assembly 300 rotates, which is beneficial to improving the user experience. It can also extend the service life of the air guide assembly 300, ensure the stable operation of the air guide assembly 300, improve the air guiding effect of the air guide assembly 300, and thus improve the stability and reliability of the air conditioner operation.

[0055] In some specific embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the bearing assembly 500 may include a bearing body 510, a mounting hole 221 is provided at the center of the fixed bracket 200, the bearing body 510 is disposed in the mounting hole 221, and the rotating part 320 passes through the bearing body 510 and is connected to the motor shaft 410 for transmission.

[0056] The outer ring of the bearing body 510 can be interference-fitted with the inner wall of the mounting hole 221, and the inner ring of the bearing body 510 is fitted onto the rotating part 320 and interference-fitted with it. This arrangement allows the bearing body 510 to be stably positioned between the fixed bracket 200 and the rotating part 320, thereby reducing the frictional resistance between the rotating part 320 and the fixed bracket 200, facilitating the rotation of the air guide assembly 300 relative to the fixed bracket 200.

[0057] Additionally, the bearing assembly 500 may include a bearing limiting member 520, which is connected to the fixed bracket 200 and stops on the side of the bearing body 510 facing the windward guide assembly 300.

[0058] For example, the bearing limiting member 520 can be connected to the fixed bracket 200 by snap-fit ​​or bolt connection. In this way, the bearing limiting member 520 can limit the bearing body 510 on the side facing the air outlet grille 330 to prevent the bearing body 510 from detaching from the fixed bracket 200.

[0059] In some specific embodiments of this utility model, such as Figure 4 , Figure 7 and Figure 8 As shown, the air conditioner may also include an air outlet grille 330, which is located on the side of the air guide assembly 300 facing away from the fixed bracket 200. The air outlet grille 330 is fixed to the air guide assembly 300, or the air outlet grille 330 is fixed to the panel frame 100.

[0060] In other words, the air outlet grille 330 can be located on the side of the air guide assembly 300 facing the air outlet 110. The air outlet grille 330 can be used to guide the airflow at the air outlet 110, which can prevent the airflow from blowing directly and improve comfort.

[0061] The air outlet grille 330 can be fixed to the air guide assembly 300. For example, the air outlet grille 330 and the air guide assembly 300 can be detachably connected by screws or snaps. When the drive motor 400 is running, the air outlet grille 330 can rotate with the air guide assembly 300. The air outlet grille 330 can guide the airflow more flexibly, so that the air guide assembly 300 can be used to achieve multi-angle air delivery, resulting in a better user experience.

[0062] Alternatively, the air outlet grille 330 can be fixed to the panel frame 100, that is, the air outlet grille 330 is fixed and does not rotate with the air guide assembly 300. This helps to simplify the structure of the air guide assembly 300 and facilitates the processing and assembly of the air guide assembly 300.

[0063] In some specific embodiments of this utility model, such as Figure 4 As shown, the air guide assembly 300 may include a frame 310, which is connected to a drive motor 400. An air outlet grille 330 is connected to the side of the frame 310 facing away from the fixed bracket 200. In this way, the drive motor 400 can drive the frame 310 to rotate, thereby driving the air guide assembly 300 to rotate.

[0064] In addition, such as Figure 6 and Figure 8 As shown, the air guide assembly 300 may include a plurality of air guide plates 340, which are rotatably connected to the frame 310. The plurality of air guide plates 340 are arranged along the radial direction of the frame 310 and are located on the side of the frame 310 opposite to the air outlet grille 330.

[0065] It should be noted that the multiple air guide plates 340 can be rotated to be parallel to the plane where the air outlet 110 is located. At this time, the edges of two adjacent air guide plates 340 overlap without gaps. That is, the multiple air guide plates 340 can close the air outlet 110. However, by adjusting the angle of the air guide plates 340, adjacent air guide plates 340 can be spaced apart, thereby opening the air outlet 110 and changing the direction of the airflow using the air guide plates 340.

[0066] Multiple air guide plates 340 can be connected by connecting rods 341, which allows multiple air guide plates 340 to rotate synchronously. This makes it easier to control the rotation of multiple air guide plates 340. Furthermore, by adjusting the direction of the air guide plates 340, 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 so that the air conditioner can deliver air better.

[0067] In addition, the air guide plate 340 can be driven by a motor. When the drive motor 400 drives the air guide assembly 300 to rotate around the center of the air outlet 110, the motor can also synchronously drive the air guide plate 340 to rotate relative to the frame 310, so as to more flexibly change the flow direction of the airflow. Thus, the air guide assembly 300 can be used to achieve multi-angle air delivery, resulting in a better user experience.

[0068] Furthermore, such as Figure 4 As shown, the rotating part 320 is constructed on the side of the frame 310 facing the fixed bracket 200, and the frame 310 is connected to the motor shaft 410 through the rotating part 320.

[0069] The rotating part 320 can be entirely composed of the frame 310, and the frame 310 is connected to the drive motor 400 and the air outlet grille 330 respectively. This not only reduces the number of parts in the air guide assembly 300 and makes assembly more convenient, but also reduces production costs.

[0070] Alternatively, part of the structure of the rotating part 320 can be formed by the frame 310, while another part of the structure of the rotating part 320 can be formed by connecting other components with the frame 310. This makes the structure of the air guide assembly 300 more flexible, easier to process and assemble, and improves production efficiency.

[0071] In some specific embodiments of this utility model, such as Figure 4 and Figure 10 As shown, the air guide assembly 300 may also include a transmission gear 350, 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 350 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 360, which is connected to the frame 310 and covers the mounting cavity 311. A portion of the transmission gear 350 extends out from the cover plate 360 ​​and is connected to the motor shaft 410 for transmission.

[0073] By adding a transmission gear 350, the drive motor 400 can drive the frame 310 to rotate, thereby driving the air guide assembly 300 to rotate. This eliminates the need to directly construct the rotating part 320 on the frame 310, which simplifies the structure of the frame 310, facilitates its processing, and reduces its weight. This, in turn, reduces the overall weight of the air guide assembly 300, making the overall structure of the air conditioner lighter and facilitating its transportation and installation, thus reducing transportation and installation costs.

[0074] The frame 310 may be constructed with a positioning groove 313, and a positioning shaft 352 may be provided on the side of the transmission gear 350 facing the air outlet grille 330. The positioning shaft 352 is connected in the positioning groove 313, which can pre-position the assembly of the transmission gear 350 and the frame 310, and facilitates the simplification of the assembly steps.

[0075] In some specific embodiments of this utility model, such as Figure 4 and Figure 10 As shown, the transmission gear 350 has a transmission shaft 351 on the side facing the drive motor 400, and the cover plate 360 ​​has an axial fitting part 361. The transmission shaft 351 passes through the axial fitting part 361, and the transmission shaft 351 and the axial fitting part 361 together define the rotating part 320.

[0076] The drive shaft 351 can be connected to the motor shaft 410 for transmission. The axial mating part 361 can extend into and mate with the bearing assembly 500. Furthermore, the limiting boss 321 can be provided on the outer peripheral surface of the axial mating part 361. Thus, the drive motor 400 can transmit power to the transmission gear 350 through the drive shaft 351, thereby driving the frame 310 to rotate. The axial mating part 361 can mate with the bearing assembly 500 and provide axial limiting for the guide assembly.

[0077] In other specific embodiments of this utility model, such as Figure 10 As shown, a transmission shaft 351 is provided on the side of the transmission gear 350 facing the drive motor 400. The transmission shaft 351 extends from the cover plate 360 ​​and is configured as a rotating part 320.

[0078] In other words, the rotating part 320 is defined solely by the drive shaft 351. The drive shaft 351 can be connected to the motor shaft 410 for transmission, and the drive shaft 351 can cooperate with the bearing assembly 500. The limiting boss 321 can be provided on the outer peripheral surface of the drive shaft 351. This simplifies the structure of the cover plate 360, 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 5As 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] In addition, the fixed bracket 200 may include a connecting arm 220, which extends radially along the fixed bracket 200, and the two ends of the connecting arm 220 are respectively connected to the radially opposite sides of the annular connecting frame 210. The drive motor 400 and the bearing assembly 500 are both fixed to the connecting arm 220.

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

[0082] The bearing assembly 500 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 bearing assembly 500, 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] In addition, the mounting hole 221 can be located at the center of the connecting arm 220 along its length and can correspond to the center of the air guide assembly 300. In this way, the motor shaft 410 of the drive motor 400 fixed in the mounting hole 221 can correspond to the rotating part 320 of the air guide assembly 300, and the motor shaft 410 and the rotating part 320 are connected in a transmission manner. In this way, the drive motor 400 can directly drive the air guide assembly 300 to rotate around the axis where its center is located through the motor shaft 410 and the rotating part 320. The structure is simple and reasonable. It can not only improve the smoothness of the rotation of the air guide assembly 300 so that the air guide assembly 300 can guide the air better, but also reduce the number of parts that are connected in a transmission manner between the drive motor 400 and the air guide assembly 300. This is conducive to simplifying the assembly structure, facilitating assembly, and reducing production costs.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.
