[0034] At present, because the wind wheel is installed on the motor shaft of the motor, the overall width of the fan is too large, and the mesh cover and the fan are installed on the outdoor unit through the motor bracket. Due to factors such as the safety distance between the motor bracket and the radiator, the thickness of the bracket, the installation distance between the wind wheel and the motor bracket, and the mesh cover, the width of the outdoor unit is too large, which is not conducive to the miniaturization design of the outdoor unit.

[0035] The utility model provides an air supply component, which is mainly used in an outdoor unit 100 of an air conditioner to accelerate the heat exchange process in the outdoor unit 100.

[0036] Reference Figures 1 to 3 In the embodiment of the utility model, the air supply assembly includes an air outlet mesh cover 10, a drive motor 20 and an axial flow fan wheel 30; the drive motor 20 includes an inner stator assembly 21 and an outer rotor assembly 22 arranged on the outer ring of the inner stator assembly 21, the inner stator assembly 21 is fixedly mounted on the air outlet mesh cover 10, and the outer rotor assembly 22 is rotatably connected to the inner stator assembly 21; the outer rotor assembly 22 is drivingly connected to the axial flow fan wheel 30, so that the width of the air supply assembly is greatly reduced, and then, the overall width of the outdoor unit 100 is effectively reduced, and the outdoor unit 100 is miniaturized. In addition, the air outlet mesh cover 10, the drive motor 20 and the axial flow fan wheel 30 are assembled into an integrated structure, which helps the air supply assembly to be assembled to the outdoor unit 100 as a whole, thereby improving the assembly efficiency. The width is the extension direction of the motor shaft of the drive motor 20.

[0037] The fan includes a drive motor 20 and an axial flow fan wheel 30. In the present embodiment, the drive motor 20 is configured as an outer rotor motor, and the outer rotor motor includes an inner stator assembly 21 and an outer rotor assembly 22 that are rotatably matched, wherein the inner stator assembly 21 is fixedly connected to the air outlet mesh cover 10, and its installation method includes but is not limited to screw locking, mortise and tenon, snap connection, etc., so that the drive motor 20 and the air outlet mesh cover 10 are an integrated structure, the connection strength between the drive motor 20 and the air outlet mesh cover 10 is improved, and the use of components such as motor brackets is reduced, the cost of components is reduced, and then the width of the air supply assembly is reduced. At the same time, the obstruction of the airflow by components such as motor brackets is avoided, and the influence on the air volume and noise of the outdoor unit 100 is reduced, so as to achieve a large air volume and low noise air supply effect.

[0038] The outer rotor assembly 22 is fixed with an axial flow wind wheel 30. Figure 6 As shown, compared with the assembly method of fixing the axial flow fan wheel 30 on the motor shaft, the installation dimensions of the drive motor 20 and the axial flow fan wheel 30 are further reduced, and the drive motor 20 is directly fixed on the mesh cover, which greatly reduces the width of the air supply assembly.

[0039] In the technical solution of the utility model, by assembling the air outlet mesh cover 10, the drive motor 20 and the axial flow fan wheel 30 into an integrated structure, it is helpful to assemble the air supply assembly to the outdoor unit 100 as a whole, reduce the steps of assembling the outdoor unit 100, and improve the assembly efficiency. Specifically, the drive motor 20 is configured as an outer rotor motor, and the axial flow fan wheel 30 is connected through the outer rotor assembly 22, and the inner stator assembly 21 is directly installed on the mesh cover, which can not only reduce the installation size of the drive motor 20 and the axial flow fan wheel 30, but also reduce the use of components such as motor brackets, and then reduce the width of the air supply assembly to a certain extent, realize the miniaturization of the outdoor unit 100, and improve the connection strength between the drive motor 20 and the air outlet mesh cover 10, and at the same time, avoid the obstruction of the wind flow by components such as motor brackets, and reduce the impact on the air volume and noise of the outdoor unit 100.

[0040] Since the driving motor 20 will generate certain vibrations when it is running, Figure 1 As shown, in one embodiment, a shock absorbing pad 40 is provided between the inner stator assembly 21 and the air outlet mesh cover 10, wherein the shock absorbing pad 40 has the effect of reducing vibration and noise. The shock absorbing pad 40 is arranged at the connection between the drive motor 20 and the air outlet mesh cover 10. During assembly, the shock absorbing pad 40 can be pre-installed on the inner stator assembly 21 and / or the air outlet mesh cover 10, and then the inner stator assembly 21 and the air outlet mesh cover 10 are fixed to ensure the assembly reliability and working reliability of the drive motor 20 and the air outlet mesh cover 10, and at the same time, effectively reduce the vibration and noise of the air supply assembly, thereby reliably reducing the noise of the outdoor unit 100 and improving the comfort of the user. The shock absorbing pad 40 can be made of shock absorbing materials such as rubber and silicone.

[0041] Specifically, the outer periphery of the inner stator assembly 21 is convexly provided with a mounting foot 211, the mounting foot 211 is connected to the air outlet mesh cover 10, the shock-absorbing pad 40 is sleeved on the mounting foot 211, and the shock-absorbing pad 40 is provided with a mounting groove for inserting the mounting foot 211. The mounting foot 211 is assembled and matched with the mounting groove to protect the mounting foot 211, and then the assembly of the inner stator assembly 21 and the shock-absorbing pad 40 is assembled to the air outlet mesh cover 10 together to realize the assembly of the drive motor 20 and the air outlet mesh cover 10. However, in other embodiments, the shock-absorbing pad 40 is pre-installed on the air outlet mesh cover 10.

[0042] In order to improve the connection strength and connection reliability between the mounting foot 211 and the shock absorbing pad 40, refer to Figure 1 In one embodiment, a notch 212 is provided on the side of the mounting foot 211 away from the center of the inner stator assembly 21, and a protrusion 41 matching the notch 212 is provided in the shock-absorbing pad 40. During assembly, the notch 212 is aligned with the protrusion 41 in the shock-absorbing pad 40 to ensure that the corresponding connection structures of the mounting foot 211 and the shock-absorbing pad 40 are reliably connected, such as penetrating the mounting foot 211 and the first mounting hole 43 of the shock-absorbing pad 40, which helps to improve the assembly efficiency of the shock-absorbing pad 40 and the mounting foot 211. In addition, due to the cooperation of the notch 212 and the protrusion 41, the effective contact area between the mounting foot 211 and the shock-absorbing pad 40 is effectively increased, thereby improving the connection stability between the mounting foot 211 and the shock-absorbing pad 40. However, in other embodiments, the notch 212 is formed on the shock-absorbing pad 40, and the protrusion 41 is convexly provided on the side of the mounting foot 211 away from the center of the inner stator assembly 21.

[0043] Optionally, in one embodiment, the shock-absorbing pad 40 and the mounting foot 211 are connected by fasteners. Specifically, the fasteners can be configured as screws. The shock-absorbing pad 40 and the mounting foot 211 are provided with two corresponding first mounting holes 43, which facilitates one screw to simultaneously connect the shock-absorbing pad 40 and the mounting foot 211 in series, thereby ensuring the connection between the shock-absorbing pad 40 and the mounting foot 211. At this time, the first mounting hole 43 can extend to the air outlet mesh cover 10 to form a second mounting hole 112 on the air outlet mesh cover 10 for integral assembly, so as to allow the screw to be inserted and locked together, thereby achieving the purpose of integrally setting the air outlet mesh cover 10, the shock-absorbing pad 40, and the drive motor 20, simplifying the assembly steps and improving the assembly efficiency. However, in other embodiments, the air outlet mesh cover 10 is provided with a mounting column, which can pass through the two first mounting holes 43, and the integral assembly of the three can be achieved through the threaded structure on the mounting column.

[0044] In order to further improve the assembly efficiency, in one embodiment, the surface of the shock-absorbing pad 40 facing the air outlet grille 10 is provided with a positioning protrusion 42, and the air outlet grille 10 is provided with a positioning groove 111 that cooperates with the positioning protrusion 42. Through the insertion and alignment of the positioning protrusion 42 and the positioning groove 111, the alignment efficiency of the first mounting hole 43 on the mounting foot 211 and the connecting structure on the air outlet grille 10, such as the second mounting hole 112, can be accelerated, thereby improving the assembly efficiency of the drive motor 20 and the air outlet grille 10. The positioning protrusion 42 and the shock-absorbing pad 40 are an integral structure, and their materials are also the same, and a gap can be left between the positioning protrusion 42 and the groove wall of the positioning groove 111, thereby reducing the vibration effect of the drive motor 20 on the air outlet grille 10 when the drive motor 20 is working.

[0045] Reference Figure 1 In one embodiment, a mounting platform 11 is provided on the air outlet grille 10, and the mounting platform 11 is connected to the inner stator assembly 21, wherein a positioning groove 111 is opened on the mounting platform 11, and a second mounting hole 112 is provided on the side of the positioning groove 111, and the second mounting hole 112 can be provided with two and can be configured as a threaded hole. When the mounting foot 211 is inserted into the positioning groove 111 through the positioning protrusion 42, the first mounting hole 43 on the shock absorbing pad 40 and the mounting foot 211 is correspondingly docked with the second mounting hole 112, so as to facilitate the series connection of the fasteners to the air outlet grille 10 and the drive assembly.

[0046] In addition, since the mounting platform 11 is formed on the air outlet mesh cover 10, when the drive motor 20 and the air outlet mesh cover 10 are assembled, the installation dimensions of the drive motor 20 and the air outlet mesh cover 10 are further reduced, and the width of the drive motor 20 and the air outlet mesh cover 10 after assembly can be reliably reduced.

[0047] Furthermore, in one embodiment, a plurality of mounting platforms 11 are arranged at intervals along the circumference of the air outlet mesh cover 10, and each mounting platform 11 is connected to the center of the air outlet mesh cover 10 with at least one rib 12, wherein each rib 12 extends radially with the center of the air outlet mesh cover 10 as a reference point, and is connected to each mounting platform 11, which helps to strengthen the structural strength of the portion of the air outlet mesh cover 10 corresponding to the drive motor 20, improves the deformation resistance of the air outlet mesh cover 10 at this portion, and the connection between each mounting platform 11 is more reliable, which helps to disperse the vibration transmitted from the drive motor 20 to the corresponding mounting platform 11, and weaken the impact of the vibration on the air outlet mesh cover 10 and even the entire outdoor unit 100. In this embodiment, according to factors such as the size of the air outlet grille 10 and the mounting platform 11, three mounting platforms 11 are arranged at intervals around the central axis of the air outlet grille 10. At this time, three corresponding ribs are arranged on the inner stator assembly 21, and three ribs 12 are connected to one mounting platform 11, and the three ribs 12 are arranged at intervals along the edge of the corresponding mounting platform 11 close to the center of the air outlet grille 10.

[0048] The utility model also provides an outdoor unit 100, which includes a front panel 50 and an air supply assembly. The specific structure of the air supply assembly refers to the above embodiment. Since the outdoor unit 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

In addition, the driving motor 20 and the axial flow fan wheel 30 are used to apply pressure to the wind in the shell of the outdoor unit 100, and the wind guide ring in the shell and / or the wind guide ribs on the air outlet mesh cover 10 are guided to ensure that the wind is reliably discharged from the outdoor unit 100 through the air outlet 51, thereby improving the performance of the outdoor unit 100.

[0049] Combined with reference Figures 2 to 3 In one embodiment, the air outlet mesh cover 10 is provided with at least one rotary buckle 13 along its circumference, and the front panel 50 is provided with a clamping hole 52 clamped with the rotary buckle 13. Through the rotational cooperation of the rotary buckle 13 and the clamping hole 52, the air supply component and the front panel 50 can be quickly disassembled and assembled, and multiple sets of rotary buckles 13 and clamping holes 52 are provided to facilitate the difficulty of separating the air supply component from the front panel 50.

[0050] In addition, the front panel 50 is provided with a plurality of latching holes 52 along the circumference of the air outlet 51, and a latching protrusion is provided on the rotation path after the rotary buckle 13 is inserted into the latching hole 52. At this time, the rotary buckle 13 is provided with an avoidance position cooperating with the latching protrusion. When the rotary buckle 13 is inserted into the latching hole 52, a force is applied to rotate the air outlet mesh cover 10, and the rotary buckle 13 moves accordingly, and the latching protrusion is locked into the avoidance position, thereby further increasing the difficulty of the rotary buckle 13 to detach from the front panel 50, and improving the connection strength between the air outlet mesh cover 10 and the front panel 50.

[0051] Furthermore, the air outlet mesh cover 10 and the front panel 50 are also connected by fasteners. At this time, the air outlet mesh cover 10 is provided with a first connecting hole 14, and the front panel 50 is provided with a second connecting hole 53 docking therewith. When the knob 13 is rotated into place, the first connecting hole 14 docks with the second connecting hole 53, which facilitates the fastener to pass through the first connecting hole 14 and the second connecting hole 53 for locking operation, thereby realizing rapid assembly of the air outlet mesh cover 10 and the front panel 50.

[0052] In another embodiment, the air outlet grille 10 and the front panel 50 are connected only by the snap fit between the turn buckle 13 and the snap hole 52; or, the air outlet grille 10 and the front panel 50 are connected only by fasteners. Of course, other connection methods that can achieve the assembly of the air outlet grille 10 and the front panel 50 are also applicable to the present application and are not limited here.
