The fan impeller is affected by the vibration of the motor and the compressor during rotation, resulting in uneven clearance between the radial edge of the fan impeller and the circumferential circle of the guide ring, resulting in uneven air outlet, thereby generating greater noise, affecting the user experience. Summary of the invention

[0041] The invention provides an outdoor unit of an air conditioner.

[0042] In the embodiment of the present invention, please refer to Figures 1 to 9 , the air conditioner outdoor unit comprises:

[0043] A housing, comprising a top cover 100 and a bottom plate 200;

[0044] An air guide ring 300, wherein the upper side of the air guide ring 300 is provided with a first connection portion 310 connected to the top cover 100, and the lower side of the air guide ring 300 is provided with a second connection portion 320 connected to the bottom plate 200;

[0045] The mounting frame 400 is disposed in the air guide ring 300; and

[0046] The wind turbine includes a motor 600 disposed on a mounting frame 400 and a wind wheel 500 disposed on an output shaft of the motor 600 .

[0047] In the related art, during the operation of the air-conditioning outdoor unit, the vibration of the compressor and the motor 600 will affect the wind wheel 500, causing the wind wheel 500 to vibrate synchronously. The technical solution of the present invention is to set the mounting frame 400 of the motor 600 in the air guide ring 300, so that the wind wheel 500 and the air guide ring 300 are formed as a whole through the mounting frame 400. In this way, the vibration impact brought by the compressor and the motor 600 will synchronously act on the whole formed by the wind wheel 500, the air guide ring 300 and the mounting frame 400, so as to avoid the uneven change of the circumferential gap between the radial edge of the wind wheel 500 and the air guide ring 300 due to the vibration of the wind wheel 500 and the air guide ring 300, thereby ensuring the smoothness of the air outlet of the air-conditioning outdoor unit, reducing the noise caused by the air flow disturbance during the air outlet process, and improving the user experience.

[0048] The upper side of the air guide ring 300 is mounted on the top cover 100 through the first connection part 310, and the lower side of the air guide ring 300 is mounted on the chassis 200 through the second connection part 320. The air guide ring 300 is relatively stable relative to the casing, so that the top cover 100, the chassis 200, the air guide ring 300, the mounting frame 400 and the wind wheel 500 tend to form a whole. After the vibration of the compressor is transmitted to the casing, the vibration of the air guide ring 300 relative to the casing can be reduced, thereby improving the installation stability of the air guide ring 300, avoiding abnormal noise and ensuring the smoothness of the air outlet. Here, the air guide ring 300 can be separated from the front panel 700. When assembling the air conditioner outdoor unit, the air guide ring 300 is connected to the front panel 700 by means of snap connection or screw connection.

[0049] It can be understood that the air guide ring 300 is first formed into a whole with the mounting frame 400, and then the motor 600 is installed on the mounting frame 400, and then the air guide ring 300 is fixed to the casing, and the installation of the air conditioner outdoor unit is completed. Similarly, when disassembly, inspection or maintenance is required, the motor 600 is first removed from the mounting frame 400, and then the air guide ring 300 is removed from the casing. Compared with the operation of independently installing the air guide ring 300 and the mounting frame 400 on the casing, this solution improves the operational convenience for technicians to disassemble and assemble the air conditioner outdoor unit.

[0050] Since the motor 600 is fixed on the mounting frame 400, and the mounting frame 400 is arranged in the air guide ring 300, it can be known that the wind wheel 500 is arranged at one end of the motor 600 away from the mounting frame 400, that is, the motor 600 is arranged on the air outlet flow path of the wind wheel 500. In this way, during the operation of the fan, the airflow driven by the wind wheel 500 will flow through the surface of the motor 600, and then be discharged into the environment through the air guide ring 300, thereby effectively controlling the temperature of the motor 600 and improving the continuous operation time of the fan. In addition, the motor 600 is directly installed on the mounting frame 400 in the air guide ring 300. Compared with the space in the housing except the air guide ring 300 for the installation of the wind wheel 500 and the motor 600, in this solution, the motor 600 will occupy a small amount of space in the housing except the air guide ring 300, thereby improving the available space of the wind wheel 500, which can increase the available space of the air conditioner outdoor unit or reduce the volume of the air conditioner outdoor unit.

[0051] In one embodiment, please refer to Figures 1 to 9 , the mounting frame 400 is fixed to the air guide ring 300 by welding. It should be noted that welding is a strong connection method. Welding can form a lasting metal bond between the mounting frame 400 and the air guide ring 300 to resist stress such as bending, vibration and external force. The mounting frame 400 is fixed to the air guide ring 300 by welding, which can ensure a firm and reliable connection and maintain the stability of the connection. In addition, the welding connection is permanent and does not require additional fasteners or fixing devices. By welding and fixing the mounting frame 400 to the air guide ring 300, the installation and maintenance process can be simplified, which simplifies the installation steps and reduces the risk of loosening or falling off. It can be understood that welding is often used in metal materials. In this way, the materials of the mounting frame 400 and the air guide ring 300 are both made of metal, which is conducive to providing effective support for the motor 600, and the metal air guide ring 300 can improve the rigidity of the air guide ring 300, is not easy to deform, and ensures the air guide ring 300 to guide the airflow. Of course, in other embodiments, the mounting frame 400 may also be fixed to the air guide ring 300 by screwing.

[0052] In one embodiment, please refer to Figure 2 and Figure 8The mounting frame 400 includes a main rod 410 and a secondary rod 420 connected to each other. The main rod 410 extends in the lateral direction, and the end of the main rod 410 is connected to the air guide ring 300. It should be noted that the lateral direction is the horizontal direction or the nearly horizontal direction, and the main rod 410 extends in the horizontal direction. As the main force-bearing member supporting the motor 600, the main rod 410 can not only provide gravity support for the motor 600, but also play the role of resisting the vibration of the motor 600. The secondary rod 420 and the main rod 410 form a frame structure, thereby enhancing the stability of the entire mounting frame 400. In addition, both ends of the main rod 410 are connected to the air guide ring 300, which can support the interior of the air guide ring 300 and improve the stability of the air guide ring 300 under the diversion effect. In addition, the presence of the auxiliary rod 420 can effectively reduce the possibility of the vibration of the compressor or the motor 600 being transmitted between the air guide ring 300 and the wind wheel 500. Since there is a connection point between the auxiliary rod 420 and the main rod 410, the vibration can be absorbed and damped to a certain extent, thereby reducing the impact of the vibration on the air guide ring 300. Specifically, the main rod 410 can be arranged in multiple pieces, arranged in parallel to form a plate-like structure, or multiple main rods 410 can be arranged at intervals, and the auxiliary rod 420 is used to strengthen the connection stability between the main rods 410. Of course, in other embodiments, the mounting frame 400 can be arranged with a fixing portion for fixing the motor 600 in the middle, and a connecting rod is provided between the outer peripheral side of the fixing portion and the inner peripheral side of the air guide ring 300, and the connecting rod extends in the radial direction of the air guide ring 300 to fix the motor 600 in the air guide ring 300, or the mounting frame 400 is arranged in a plate shape, and a plurality of air outlets are opened on the plate-like mounting frame 400 to reduce wind resistance.

[0053] Further, in this embodiment, please refer to Figures 1 to 9 The middle of the mounting frame 200 is provided with a motor mounting hole 430, and the motor mounting hole 430 is used for the motor 600 to be installed. The mounting frame 400 is connected to the motor 600 in the middle adjacent to the motor 600, so that the motor 600 can be stably installed in the mounting frame 400, and the available space in the housing will be increased, which is convenient for layout and adjustment of the distribution of components in the air conditioner outdoor unit. Of course, in other embodiments, the end of the motor 600 can be mounted on the mounting frame 400 in a close fit.

[0054] Specifically, in this embodiment, please refer to Figures 1 to 9, the outer periphery of the motor 600 is provided with a mounting lug 610, the connection between the main rod 410 and the auxiliary rod 420 is provided with a first mounting hole 414, the end of the auxiliary rod 420 is provided with a second mounting hole 421, and the fastener passes through the first mounting hole 414, the second mounting hole 421 and the mounting lug 610 in sequence to mount the motor 600 on the mounting frame 400. It should be noted that the mounting lug 610 is located in the middle of the axial direction of the motor 600, and one end of the motor 600 extends into the accommodation space surrounded by the main rod 410 and the auxiliary rod 420. The fastener is configured as a screw. Through the setting of the first mounting hole 414 and the second mounting hole 421, the fastener is passed through these holes to clamp the main rod 410 and the auxiliary rod 420, and then the fastener is connected to the mounting lug 610 to enhance the stability of the connection between the motor 600 and the mounting frame 400. Moreover, the mounting lug 610, the first mounting hole 414 and the second mounting hole 421 provide clear positioning and alignment points, making it more convenient to install the fasteners. Similarly, when the motor 600 and the mounting frame 400 need to be disassembled, the connection can be easily released by simply loosening the fasteners. Such a connection method can simplify the installation and disassembly process of the motor 600. In addition, the rod sections of the main rod 410 and the auxiliary rod 420 corresponding to the accommodating space are arranged in an arc shape convexly arranged in opposite directions to improve the compactness of the mounting frame 400. Of course, in other embodiments, the outer peripheral side of the motor 600 is independently connected to the auxiliary rod 420 and the main rod 410, rather than being connected to the connection between the main rod 410 and the auxiliary rod 420.

[0055] Further, in this embodiment, please refer to Figures 1 to 9 , the mounting frame 400 is provided with an arched section 415 arched toward the wind wheel 500, and the motor mounting hole 430 is provided in the arched section 415. It can be understood that the rod section of the main rod 410 different from the arched section 415 is located on the wind path of the wind wheel 500, so that the arched section 415 of the main rod 410 can make the motor 600 close to the middle of the mounting frame 400 connected to the mounting frame 400 to ensure the stability of the motor 600 on the mounting frame 400, and the motor 600 is farther away from the front panel 700 relative to the air guide ring 300, and the shell ensures the gap between the front panel 700 and the air guide ring 300 to reduce the vibration and noise of the air guide ring 300 during the air outlet process. In addition, the arched section 415 can increase the structural strength and stability of the main rod 410, the auxiliary rod 420 in this embodiment is connected to the arched section 415, and the motor 600 is also installed on the arched section 415, thereby improving the structural strength of the mounting frame 400 and the installation stability of the motor 600. Of course, in other embodiments, the main rod 410 is in a straight state, that is, the mounting frame 400 extends straight in the horizontal direction.

[0056] In one embodiment, please refer to Figures 1 to 9The mounting frame 400 includes two main rods 410 and two auxiliary rods 420. The two auxiliary rods 420 are connected in parallel between the two main rods 410 to enclose a motor mounting hole 430. In this way, the airflow delivered by the wind wheel 500 passes through the main rod 410 more smoothly, reducing the air resistance of the mounting frame 400 and reducing the force on the main rod 410, which helps to improve the air flow efficiency of the air conditioner outdoor unit, and can reduce the friction between the main rod 410 and the airflow and the possibility of vibration of the main rod 410, which helps to reduce the noise level and reduce the vibration of the equipment, providing a quieter and more stable operating environment. Moreover, in terms of the distribution of the main rod 410, the motor 600 is smaller than the inner ring of the air guide ring 300. The design of the mounting frame 400 can make the installation and maintenance of the motor 600 more convenient. When the motor 600 needs to be removed for inspection, the technician manually removes the motor 600 from the main rod 410 and the auxiliary rod 420, and then reaches into the casing to disassemble the motor 600 and the wind wheel 500, and then takes out the motor 600, or removes the air guide ring 300, and then takes out the fan. Compared with the existing method of removing the air guide ring 300 and then removing the mounting frame 400, the present solution can directly remove the motor 600 from the mounting frame 400 and then take out the motor 600, thereby improving the convenience of inspecting the motor 600. It can be understood that in the structural form of the mounting frame 400 of the above embodiment, only the main rod 410 or the connecting rod is located on the air outlet path of the wind wheel 500. Since the main rod 410 and the connecting rod are relatively small in size, their influence on the air outlet of the wind wheel 500 is almost negligible.

[0057] Further, in this embodiment, please refer to Figures 1 to 9The main rod 410 includes a main board 411 and two reinforcing flanges 412. The two reinforcing flanges 412 are arranged on the same side of the main board 411 and are arranged opposite to each other to surround a groove-shaped structure. The presence of the reinforcing flanges 412 can form a frame structure or a reinforced edge on the same side of the main board 411, provide better support and stability, prevent the main rod 410 from bending or deforming, and thus effectively increase the structural strength of the main rod 410. In addition, the two reinforcing flanges 412 are arranged opposite to each other, and they can support and balance the pressure on each other, further enhancing the structural stability of the main rod 410. This design helps to reduce vibration and shaking and maintain the stable operation of the motor 600. Of course, in other embodiments, the main board 411 can be configured as a solid rod-shaped member. Without loss of generality, at least one of the groove-shaped structures of the main pole 410 is configured as a wiring groove 440, and a limiting baffle 450 is provided at the notch of the wiring groove 440. At the same time, the notch of the wiring groove 440 is opened toward the side away from the wind wheel 500, which can reduce the wind resistance of the main pole 410 and improve the stability of the mounting frame 400. In this way, the conductive wires of the motor 600 are arranged in the wiring groove 440, and the limiting baffle 450 can prevent the conductive wires from falling and affecting the air outlet, so as to ensure the stability of the power supply to the motor 600. Of course, in other embodiments, the conductive wires of the motor 600 can also be stably tied to the main pole 410 by a strap.

[0058] In one embodiment, please refer to Figures 2 to 9 At the connection between the secondary rod 420 and the main rod 410, the reinforcing flange 412 is provided with an avoidance notch 413, and the secondary rod 420 is connected to the main board 411 through the avoidance notch 413. It can be understood that the main force-bearing component of the main rod 410 is the main board 411, and the setting of the avoidance notch 413 can make the secondary rod 420 more closely connected to the main board 411, increase the abutment area, improve the strength and stability of the connection, and ensure that the connection between the secondary rod 420 and the main rod 410 is firm and reliable. In addition, the avoidance notch 413 provides a positioning reference for the connection, and the secondary rod 420 can be easily inserted and removed, so that the connection or disassembly between the secondary rod 420 and the main rod 410 will be more convenient, thereby facilitating the technician to install, repair and maintain the mounting frame 400. Of course, in other embodiments, the secondary rod 420 can be connected to the side of the main board 411 away from the reinforcing flange 412.

[0059] In one embodiment, please refer to Figures 1 to 9The first connection part 310 includes a first connection plate 311 and a second connection plate 312 which are arranged at an angle and connected. The first connection plate 311 is connected to the air guide ring 300, and the second connection plate 312 is opposite to and connected to the top cover 100. The first connection plate 311 and the second connection plate 312 are arranged at an angle and connected to each other, so that a strong connection can be provided. This connection method can increase the stability and reliability of the connection. The first connection plate 311 is connected to the air guide ring 300, and the second connection plate 312 is opposite to and connected to the top cover 100, so that the entire structure can be firmly fixed together.

[0060] Further, in this embodiment, please refer to Figures 1 to 9 , the top cover 100 is provided with a first mounting protrusion 110 protruding downwardly corresponding to the second connecting plate 312, and the second connecting plate 312 is connected to the first mounting protrusion 110. The existence of the first mounting protrusion 110 on the top cover 100 can improve the strength of the entire structure. They increase the contact area and the number of connection points between the connecting parts, so that more forces can be dispersed and absorbed, and the deformation and damage risks of the structure can be reduced. In this way, a stable connection effect is achieved through the connection between the first mounting protrusion 110 on the top cover 100 and the second connecting plate 312. This connection method can ensure a firm connection between the top cover 100 and the second connecting plate 312 and enhance the stability of the entire structure. In addition, the first mounting protrusion 110 also provides a positioning function for the installation of the air guide ring 300, making it easier to position and align the air guide ring 300 and the top cover 100. Such a design can reduce assembly steps and time and improve production efficiency. Of course, in other embodiments, the second connecting plate 312 can be directly connected to the top cover 100.

[0061] Further, in this embodiment, please refer to Figure 8 and Fig. 9, the cover edge of the top cover 100 is provided with a positioning notch 120 corresponding to the first connecting plate 311. Thus, when the technician installs the air guide ring 300 on the housing, the technician first aligns the first connecting plate 311 with the positioning notch 120, and then installs the air guide ring 300 on the housing. That is, the positioning notch 120 provides a positioning function for the technician's installation operation, making it easier to position and align the air guide ring 300, the top cover 100, and the chassis 200. It should be noted that the side frame of the air-conditioning outdoor unit cooperates with the flange at the edge of the chassis 200 and the cover edge at the edge of the top cover 100, so that the casing forms a relatively stable whole, and the cover edge of the top cover 100 is provided with a positioning notch 120 corresponding to the first connecting portion 310. Since the first connecting portion 310 and the second connecting portion 320 are respectively connected to the top cover 100 and the chassis 200, and the outer periphery of the top cover 100 and the chassis 200 are both provided with flanges, when the technician installs the air guide ring 300 on the casing, the second connecting portion 320 is first opposite to the second mounting protrusion 210, and the air guide ring 300 is adjusted from an inclined state to a vertical state. During this process, the first connecting portion 310 passes through the positioning notch 120, and then the second connecting plate 312 is opposite to the first mounting protrusion 110, thereby realizing the installation of the air guide ring 300 in the casing. In this way, the convenience of pre-installing the air guide ring 300 is improved.

[0062] In one embodiment, please refer to Figures 1 to 9 , the outer periphery of the chassis 200 is provided with a flange, and the second connection part 320 is connected to the flange of the chassis 200. The second connection part 320 is connected to the flange at the edge of the chassis 200, which can reduce the gap between the air guide ring 300 and the front panel 700 to ensure that the gap between the panel and the air guide ring 300 meets the wind noise requirement. In addition, the connection between the second connection part 320 and the chassis 200 is opposite to the front panel 700. The technician can remove the front panel 700 and disconnect the connection between the second connection part 320 and the flange of the chassis 200, thereby improving the convenience of technicians in disassembling and assembling the air guide ring.

[0063] Further, in this embodiment, please continue to refer to Figures 1 to 9, the connection direction of the second connection part 320 and the flange of the chassis 200 is at an angle to the connection direction of the second connection plate 312 and the top cover 100, and tends to be perpendicular to each other. When the motor 600, the compressor or external force factors cause the air guide ring 300 to vibrate, the force directions of the second connection part 320 and the second connection plate 312 are at an angle, which can enable the air guide ring 300 to maintain good stability in the horizontal vertical direction, and make it more resistant to torsion and vibration, thereby reducing the risk of deformation and damage of the structure. Of course, in other embodiments, the first connection part 310 and the second connection part 320 are respectively connected to the flange at the edge of the top cover 100 and the flange at the edge of the chassis 200, or the first connection part 310 and the second connection part 320 are respectively opposite to and connected to the top cover 100 and the chassis 200.

[0064] Further, in this embodiment, please refer to Figures 1 to 9 , the flange of the chassis 200 is provided with a second mounting protrusion 210 protruding toward the second connection part 320, and the second connection part 320 is connected to the second mounting protrusion 210. It can be understood that the existence of the second mounting protrusion 210 of the chassis 200 can improve the strength of the entire structure. They increase the contact area and the number of connection points between the connecting parts, so that more forces can be dispersed and absorbed, and the deformation and damage risks of the structure can be reduced. In this way, a stable connection effect is achieved through the connection between the second mounting protrusion 210 on the chassis 200 and the second connection part 320. This connection method can ensure a firm connection between the chassis 200 and the second connection part 320 and enhance the stability of the entire structure. In addition, the second mounting protrusion 210 also provides a positioning function for the installation of the air guide ring 300, making it easier to position and align the air guide ring 300 and the chassis 200. Such a design can reduce assembly steps and time and improve production efficiency. Of course, in other embodiments, the second connection part 320 can also be directly connected to the flange of the chassis 200.

[0065] Further, in this embodiment, please continue to refer to Figures 1 to 9 The lower end of the second connection part 320 is provided with an abutting flange 321, and the abutting flange 321 abuts against the bottom wall of the chassis 200. In this way, after the air guide ring 300 is installed in the housing, the abutting flange 321 can provide support for the air guide ring 300 to reduce the force between the second connection part 320 and the second mounting protrusion 210 in the vertical direction, and cooperate with the second connection plate 312 and the first mounting protrusion 110, thereby ensuring the stability of the air guide ring 300 in the vertical direction.

[0066] Specifically, in this embodiment, please refer to Fig. 9, the first connection part 310 and the second connection part 320 are connected to the housing by screw locking, or one of the first connection part 310 and the second connection part 320 is connected to the housing by screw locking. By using the screw locking method, the first connection part 310 can form a firm connection with the top cover 100, and the second connection part 320 can form a firm connection with the top plate. At the same time, when the equipment needs to be repaired or parts are replaced, the screws can be easily untied, making maintenance work more efficient and reducing maintenance time. In addition, by loosening or tightening the screws, the tightness between the first connection part 310 and the top cover 100, the second connection part 320 and the chassis 200 can be adjusted to ensure that the tightness of the connection adapts to different needs and environments. Of course, in other embodiments, the first connection part 310 and the second connection part 320 are respectively connected to the top cover 100 and the chassis 200 by snap-on connection.

[0067] The present invention also provides an air conditioner, which includes an air conditioner indoor unit and an air conditioner outdoor unit. The specific structure of the air conditioner outdoor unit refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Of course, in other embodiments, the air conditioner can also be set as an integrated air conditioner.

[0068] The air conditioner of the present invention can be a split-type air conditioner that is easy for users to install personally. It uses a flexible refrigerant pipe to connect the indoor heat exchanger of the air conditioner indoor unit and the outdoor heat exchanger of the air conditioner outdoor unit, and injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the air conditioner indoor unit and the air conditioner outdoor unit separately, without assembling the refrigerant pipe and filling the refrigerant, thereby reducing the difficulty of installation and realizing personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner of the present invention can also be an ordinary split-type air conditioner.
