[0037] The utility model provides an outdoor unit of an air conditioner.

[0038] Reference Figures 1 to 6 In an embodiment of the utility model, the air-conditioning outdoor unit includes a shell 10, an electric control box 20 and an air supply assembly 30. The shell 10 includes a front panel 11, and the front panel 11 is provided with an air outlet 111; the electric control box 20 is arranged in the shell 10; the air supply assembly 30 is covered at the air outlet 111, and includes an air outlet mesh cover 31, a drive motor 32 and an axial flow fan wheel 33. The motor line 321 of the drive motor 32 is fixed to the air outlet mesh cover 31, and the motor line 321 is detachably connected to the control line 21 of the electric control box 20 in the shell 10. With such a configuration, the outdoor unit can be quickly assembled and maintained by directly disassembling the air supply assembly 30, and the wiring method in the shell 10 is simplified to achieve quick connection and disconnection of the motor line 321 and the control line 21, thereby effectively improving the disassembly and maintenance efficiency of the air-conditioning outdoor unit.

[0039] The air supply assembly 30 is covered on the air outlet 111, specifically, the air outlet mesh cover 31 is covered on the air outlet 111, and the driving motor 32 and the axial flow fan wheel 33 are extended into the shell 10 together, so that the steps of assembling the outdoor unit can be reduced and the assembly efficiency can be improved.

[0040] Specifically, the fan includes a drive motor 32 and an axial flow fan wheel 33. In this embodiment, the drive motor 32 can be configured as an outer rotor motor. At this time, the inner stator component of the drive motor 32 is fixedly connected to the air outlet mesh cover 31. The installation method includes but is not limited to screw locking, mortise and tenon, buckle connection, etc., so that the drive motor 32 and the air outlet mesh cover 31 are an integrated structure, and the outer rotor component of the drive motor 32 is connected to the axial flow fan wheel 33. In the axial direction of the air outlet 111, the installation size of the drive motor 32 and the axial flow fan wheel 33 can be reliably reduced. The drive motor 32 is directly fixed on the mesh cover to achieve an integrated design of the air outlet mesh cover 31, the drive motor 32 and the axial flow fan wheel 33. In addition, the use of components such as motor brackets can be reduced, the cost of components can be reduced, the width of the air supply component 30 can be reduced to a certain extent, and at the same time, the motor bracket and other parts can be avoided from blocking the wind flow, reducing the impact on the air volume and noise of the outdoor unit, and achieving a large air volume and low noise air supply effect. Of course, in other embodiments, the axial flow fan wheel 33 is connected to the motor shaft of the drive motor 32.

[0041] Because the driving motor 32 is directly fixed on the air outlet mesh cover 31 , the motor line 321 of the driving motor 32 is fixed on the air outlet mesh cover 31 , the wiring is simple, and the installation stability of the motor line 321 can be ensured, which is beneficial to the later connection of the motor line 321 with the control line 21 in the shell 10 .

[0042] The motor line 321 and the control line 21 are connected through the male and female terminals 323 to achieve a detachable connection between the motor line 321 and the control line 21. It can be understood that compared with the existing maintenance of the drive motor 32, it is necessary to first remove the top cover and the front panel 11 of the shell 10 before repairing the drive motor 32. In this embodiment, when the air supply component 30 is installed as a whole to the front panel 11, the motor line 321 and the control line 21 are first connected through the male and female terminals 323, and then the air supply component 30 is installed as a whole. It is installed on the front panel 11, and when the air supply assembly 30 is maintained later, for example, when repairing the drive motor 32, the air outlet mesh cover 31 is first separated from the front panel 11, and then the motor line 321 and the control line 21 are separated, that is, the male and female terminal blocks 323 are acted on, and the drive motor 32 and the axial flow fan wheel 33 can be directly replaced or maintained. Specifically, it is only necessary to directly remove the air outlet mesh cover 31 to replace or repair the drive motor 32, etc., which is convenient for disassembly and assembly, simplifies the disassembly and assembly steps of the air conditioner outdoor unit, and improves the convenience of disassembly and assembly and maintenance.

[0043] In the technical solution of the utility model, the air supply assembly 30 is fixedly installed on the front panel 11 in an integral manner, and the motor line 321 and the control line 21 are connected through the male and female terminal blocks 323, which can effectively reduce the steps of assembling the outdoor unit, improve the assembly efficiency, and improve the convenience of disassembly, assembly and maintenance.

[0044] Among them, the driving motor 32 is directly fixed on the air outlet mesh cover 31, which can reduce the use of components such as motor brackets, reduce component costs, and reduce the width of the air supply assembly 30 to a certain extent. At the same time, it avoids the obstruction of wind flow by parts such as motor brackets, reduces the impact on the air volume and noise of the outdoor unit, and achieves a large air volume and low noise air supply effect; in addition, it is also convenient to fix the motor wire 321 on the air outlet mesh cover 31, which is conducive to the later detachable connection of the motor wire 321 and the control wire 21.

[0045] To facilitate the connection between the motor line 321 and the control line 21, as Figure 2 As shown, in one embodiment, the front panel 11 is provided with a wire hole 112, and the wire hole 112 is arranged close to the air outlet 111. The wire hole 112 is used for the motor wire 321 to pass through or for the control wire 21 to pass through. Specifically, the wire hole 112 is a complete structure, and can be any hole-shaped structure such as a round hole, a waist-shaped hole, etc. The wire hole 112 is opened at the edge of the air outlet 111 and close to the connection between the front panel 11 and the air outlet mesh cover 31, so as to facilitate the passing of the motor wire 321 or the control wire 21.

[0046] The arrangement of the wire hole 112 can prevent the motor wire 321 from detaching from the front panel 11 through the wire hole 112 when the motor wire 321 passes through the housing 10, and can prevent the control wire 21 from detaching from the front panel 11 when the control wire 21 passes through the housing 10 through the wire hole 112, thereby ensuring a reliable connection between the motor wire 321 and the control wire 21, and reducing the possibility of the motor wire 321 and / or the control wire 21 shaking in the housing 10, thereby improving the safety of the air conditioner outdoor unit. However, in other embodiments, the front panel 11 is provided with an avoidance gap for the wire harness to pass through, and / or the front panel 11 is provided with a fixing structure for fixing the wire harness.

[0047] Specifically, in one embodiment, the electric control box 20 is located above the wire hole 112, which rationally utilizes the assembly space in the housing 10. Moreover, because the electric control box 20 is located above the wire hole 112, at this time, the control line 21 hangs down and is close to the wire hole 112, which saves effort and is convenient for finding the control line 21, and further, facilitates the wiring operation of connecting or disconnecting the motor line 321.

[0048] Reference Figure 2 and Figure 6In one embodiment, a first wire groove 311 is provided on the air outlet mesh cover 31, and the motor wire 321 is provided in the first wire groove 311. By embedding the motor wire 321 into the air outlet mesh cover 31, the possibility of the motor wire 321 protruding from the surface of the air outlet mesh cover 31 facing the axial flow fan wheel 33 is reduced, and the risk of interference between the motor wire 321 and the axial flow fan wheel 33 is reduced. It can also prevent the motor wire 321 from being suspended on the air outlet path due to being separated from the air outlet mesh cover 31 and disturbing the airflow, thereby reducing the impact on the air volume and noise of the air conditioner outdoor unit, and at the same time, improve the connection stability of the motor wire 321 on the air outlet mesh cover 31.

[0049] Furthermore, if Figure 6 As shown, in one embodiment, a plurality of first wire grooves 311 are arranged around the central axis of the air outlet grille 31, and the motor wire 321 is fixed in one of the first wire grooves 311, thereby improving the assembly flexibility of the motor wire 321, and it is only necessary to ensure that the first wire groove 311 where the motor wire 321 is installed is close to the wire hole 112 or the electric control box 20. In addition, the first wire grooves 311 are arranged at intervals around the center of the air outlet grille 31, which can ensure the reliable enhancement of the overall structural strength of the air outlet grille 31, thereby improving the reliability of the air outlet grille 31 fixing the drive motor 32.

[0050] like Figure 2 and Figure 6 As shown, in order to prevent the motor wire 321 from escaping from the first wire groove 311, in one embodiment, a first wire buckle 312 is arranged in the first wire groove 311 to restrain the movement tendency of the motor wire 321 from escaping from the first wire groove 311. Specifically, multiple first wire buckles 312 are arranged along the extension direction of the first wire groove 311, wherein two adjacent first wire buckles 312 can be arranged on the same side wall of the first wire groove 311, or respectively arranged on the opposite side walls of the first wire groove 311; the first wire buckle 312 can be composed of one fastener or two fasteners; the first wire buckle 312 can extend from the side wall or bottom wall of the first wire groove 311.

[0051] Reference Figure 6In one embodiment, the air outlet mesh cover 31 includes an inner ring 313, an outer ring 314 and a plurality of ribs 315 connected between the inner ring 313 and the outer ring 314. The first wire groove 311 is formed on at least one of the ribs 315. The ribs 315 are arranged at intervals around the center of the air outlet mesh cover 31. The ribs 315 can guide the airflow to flow out of the air conditioner outdoor unit in a better air outlet direction according to their specific structure. At this time, the first wire groove 311 is provided on the ribs On 315, it can extend along the rib 315 from the inner ring 313 of the air outlet mesh cover 31 to the outer ring 314, guide the motor line 321 to extend toward the connection between the air outlet mesh cover 31 and the front panel 11, and assist in realizing the connection between the motor line 321 and the control line 21. Since the routing direction of the first wire groove 311 is the same as the extension direction of the rib 315, the motor line 321 can avoid blocking and disturbing the wind flow, thereby ensuring that the air conditioner outdoor unit achieves a large air volume and low noise effect when working.

[0052] In order to ensure that the first wire groove 311 fixes the motor wire 321, in one embodiment, the rib 315 includes a connecting rib 3151 and a reinforcing rib 3152, and the first wire groove 311 is formed on the reinforcing rib 3152, wherein the reinforcing rib 3152 is thicker than the connecting rib 3151, which can not only enhance the structural strength of the air outlet mesh cover 31 and ensure the assembly reliability of the drive motor 32 on the air outlet mesh cover 31, but also form the first wire groove 311 with a size adapted to the motor wire 321, ensuring that the motor wire 321 is inserted into the first wire groove 311, thereby achieving reliable assembly of the motor wire 321.

[0053] Combined with reference Figures 2 to 5 In one embodiment, the electric control box 20 is provided with a second wire groove 22, and the control line 21 is arranged in the second wire groove 22; the outlet side 24 of the electric control box 20 is away from the air supply assembly 30, and the control line 21 extends from the outlet side 24 and extends toward the air outlet 111 along the second wire groove 22. It can be understood that the second wire groove 22 is formed on the box body surface of the electric control box 20. At this time, the control line 21 extending from the outlet side 24 is placed in the second wire groove 22 and extends toward the wire hole 112 or the air outlet 111 to ensure that the control line 21 The control line 21 is connected with the motor line 321, wherein a second wire buckle 23 is arranged in the second wire groove 22 to restrain the movement tendency of the control line 21 from leaving the second wire groove 22. Specifically, a plurality of second wire buckles 23 are arranged along the extension direction of the second wire groove 22, wherein two adjacent second wire buckles 23 can be arranged on the same side wall of the second wire groove 22, or respectively arranged on the opposite side walls of the second wire groove 22; the second wire buckle 23 can be composed of one fastener or two fasteners; the second wire buckle 23 can extend from the side wall or bottom wall of the second wire groove 22.

[0054] In addition, the shell 10 includes a side panel, and the electrical control box 20 is placed between the side panel and the air supply assembly 30. By setting the outlet side 24 of the electrical control box 20 facing the side panel, the outlet side 24 is set away from the air supply assembly 30, and the wiring position on the outlet side 24 faces the side panel, which facilitates the removal of the side panel to perform safety and maintenance inspections on each wiring plug on the outlet side 24 of the electrical control box 20, thereby improving the maintenance convenience of the air conditioner outdoor unit.

[0055] Reference Figure 2 and Figure 6 In one embodiment, the air outlet mesh cover 31 is provided with a mounting platform 316, and the drive motor 32 is provided with a mounting foot 322 connected to the mounting platform 316, so that the drive motor 32 can be directly fixedly mounted on the air outlet mesh cover 31 through the cooperation of the mounting platform 316 and the mounting foot 322, thereby reducing unnecessary parts such as motor brackets, and helping to reduce the installation size of the drive motor 32 and the air outlet mesh cover 31. At the same time, the airflow is prevented from being blocked by parts such as motor brackets, and the impact on the air volume and noise of the outdoor unit is reduced, and the motor line 321 and the control line 21 are conveniently connected in the housing 10. The connection methods of the mounting platform 316 and the mounting foot 322 include but are not limited to buckling, bolting, splicing, and plugging.

[0056] Reference Figures 5 to 6 In one embodiment, the air outlet mesh cover 31 is provided with at least one rotary buckle 317 along its circumference, and the front panel 11 is provided with a clamping hole 113 clamped with the rotary buckle 317; through the rotational cooperation of the rotary buckle 317 and the clamping hole 113, the air supply component 30 and the front panel 11 can be quickly disassembled and assembled, and a plurality of sets of rotary buckles 317 and clamping holes 113 are provided to facilitate the difficulty of separating the air supply component 30 from the front panel 11.

[0057] In addition, the front panel 11 is provided with a plurality of latching holes 113 along the circumference of the air outlet 111, and a latching protrusion is provided on the rotation path after the rotary buckle 317 is inserted into the latching hole 113. At this time, the rotary buckle 317 is provided with an avoidance position cooperating with the latching protrusion. When the rotary buckle 317 is inserted into the latching hole 113, a force is applied to rotate the air outlet mesh cover 31, and the rotary buckle 317 moves accordingly, and the latching protrusion is locked into the avoidance position, thereby further increasing the difficulty of the rotary buckle 317 to detach from the front panel 11, and improving the connection strength between the air outlet mesh cover 31 and the front panel 11.

[0058] Furthermore, the air outlet mesh cover 31 and the front panel 11 are connected by fasteners. At this time, the air outlet mesh cover 31 is provided with a first connecting hole 318, and the front panel 11 is provided with a second connecting hole 114 docking therewith. When the knob 317 is rotated into place, the first connecting hole 318 docks with the second connecting hole 114, which facilitates the fastener to pass through the first connecting hole 318 and the second connecting hole 114 for locking operation, thereby realizing rapid assembly of the air outlet mesh cover 31 and the front panel 11.

[0059] In another embodiment, the air outlet mesh cover 31 and the front panel 11 are connected only by the snap fit between the turn buckle 317 and the snap hole 113; or, the air outlet mesh cover 31 and the front panel 11 are connected only by fasteners. Of course, other connection methods that can achieve the assembly of the air outlet mesh cover 31 and the front panel 11 are also applicable to the present application and are not limited here.
