[0047] The utility model provides an outdoor unit.

[0048] Reference Figures 1 to 12In an embodiment of the utility model, the outdoor unit includes a shell, an air outlet mesh cover 20, a motor frame 30, a drive motor 40 and an axial flow fan wheel 50, the shell includes a front panel 10, and the front panel 10 is provided with an air outlet 11; the air outlet mesh cover 20 is covered by the air outlet 11; the motor frame 30 is connected to the edge of the air outlet 11 and protrudes toward the air outlet mesh cover 20, and the motor frame 30 is connected to the air outlet mesh cover 20; the drive motor 40 is connected to the motor frame 30, and the axial flow fan wheel 50 is transmission-connected to the drive motor 40. In this way, the drive motor 40 and the axial flow fan wheel 50 are fixed together by the air outlet mesh cover 20 and the motor frame 30, which helps to disperse the weight of the drive motor 40 and the axial flow fan wheel 50, thereby improving the assembly stability of the drive motor 40 and the axial flow fan wheel 50 in the outdoor unit.

[0049] The motor frame 30 can be integrally formed by stamping, so that the production and processing of the motor frame 30 is convenient, and its processing efficiency and processing quality can be guaranteed. Among them, since the motor frame 30 is integrally formed at the air outlet 11, the present embodiment can reasonably utilize the waste generated by stamping the front panel 10 at the air outlet 11, and use the waste as the stamping material of the motor frame 30, thereby saving the cost of the motor frame 30, and saving the assembly process between the motor frame 30 and the front panel 10. At the same time, the overall weight of the front panel 10 and the motor frame 30 is reduced, which is convenient for realizing the lightweight of the outdoor unit. Of course, in other embodiments, it can also be integrally formed by casting or injection molding.

[0050] The motor frame 30 protrudes toward the direction of the air outlet grille 20. On the one hand, the motor frame 30 can reasonably utilize the space on the front side of the front panel 10, that is, the space between the air outlet grille 20 and the front panel 10. When the air outlet grille 20 is covered on the air outlet 11, it is convenient for the motor frame 30 to abut and connect with the air outlet grille 20. The connection methods include but are not limited to plug-in, screw locking, and buckle connection, which ensure the connection strength between the motor frame 30 and the air outlet grille 20, and there is no need to widen the size of the overall outdoor unit in the front and rear directions, reducing the possibility of increasing the size of the outdoor unit, which is conducive to the miniaturization design of the outdoor unit; on the other hand, the air outlet grille 20 and the motor frame 30 are used to support and fix the drive motor 40 together. Compared with the drive motor 40 being fixed by the motor frame 30 alone, it is convenient to disperse the weight of the drive motor 40 and the axial flow fan wheel 50, and there is no need to increase the size of the motor frame 30 to ensure the stability of the drive motor 40 in the outdoor unit, which effectively reduces the weight of the motor frame 30, improves the assembly stability of the drive motor 40 and the axial flow fan wheel 50, and thus reduces noise.

[0051] In the technical solution of the utility model, the drive motor 40 and the axial flow wind wheel 50 are fixed together by the air outlet mesh cover 20 and the motor frame 30. Compared with the drive motor 40 being fixed alone by the motor frame 30, this helps to disperse the weight of the drive motor 40 and the axial flow wind wheel 50, and there is no need to increase the size of the motor frame 30 to ensure the stability of the drive motor 40 in the outdoor unit, which effectively reduces the weight of the motor frame 30 and improves the assembly stability of the drive motor 40 and the axial flow wind wheel 50.

[0052] Reference Figure 2 In one embodiment, the motor frame 30 includes a fixing seat 31 and an adapter leg 32. A plurality of the adapter legs 32 are arranged along the circumference of the fixing seat 31 and are connected to the edge of the air outlet 11. The fixing seat 31 is connected to the drive motor 40. In this way, through the supporting effect of the adapter leg 32, the fixing seat 31 can be stably connected to the air outlet 11, thereby ensuring the stable installation of the drive motor 40 and facilitating the connection between the fixing seat 31 and the air outlet mesh cover 20.

[0053] Each adapter leg 32 is arranged at intervals on the outer periphery of the fixing base 31, and its free end is connected to the edge of the air outlet 11. It can be arranged evenly or unevenly according to the specific structure and wind noise requirements to ensure the connection strength between the motor frame 30 and the front panel 10, and provide sufficient wind passing area to ensure the air volume of the outdoor unit. Specifically, Figure 2 , Fig.11 and Fig.12 As shown, the number of the adapter legs 32 can be 4, 5, or 6. Of course, in other embodiments, the number of the adapter legs 32 can also be 2, 3, 7, 8, etc., on the premise of ensuring stable support of the motor frame 30 for the drive motor 40 and large air volume of the outdoor unit.

[0054] Combined with reference Figures 7 to 8 In one embodiment, the adapter leg 32 includes a first section 321 and a second section 322 arranged at an angle, the first section 321 is connected to the fixing seat 31, and the second section 322 is connected to the first section 321, and is arranged obliquely. It can be understood that the first section 321 and the second section 322 are connected at an angle, thereby ensuring that the motor frame 30 can be protruded in front of the air outlet 11, so that it is convenient to connect the fixing seat 31 with the air outlet mesh cover 20, and reasonably use the assembly space between the air outlet mesh cover 20 and the front panel 10, which is conducive to the miniaturization design of the outdoor unit, and can provide better support for fixing the drive motor 40. However, in other embodiments, the extension direction of the second section 322 is parallel to the radial direction of the air outlet 11.

[0055] Specifically, in one embodiment, in the axial direction of the air outlet 11, the distance between the first section 321 and the front panel 10 is k, 10 mm ≤ k ≤ 25 mm; in this way, it can be ensured that the protruding distance of the motor frame 30 is large enough to provide sufficient installation space for the drive motor 40. Of course, in other embodiments, according to different needs, the distance can also be adaptively adjusted to other values.

[0056] Specifically, the distance k between the first section 321 and the front panel 10 may be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, etc.

[0057] Further, in one embodiment, the thickness of the first section 321 is h, 10 mm ≤ h ≤ 15 mm; it should be noted that the thickness of the first section 321 includes the dimension of the first section 321 in the axial direction of the air outlet 11, that is, h can be Figure 8 The h1 shown in FIG. 1 also includes the distance between the two opposite sides of the first section 321 distributed along the circumference of the air outlet 11, that is, h can be Fig. 9 h2 shown in . In this embodiment, limiting the above dimensions within a certain range can ensure the structural strength of the adapter legs 32, thereby ensuring the support capacity of the motor frame 30 for the drive motor 40, thereby ensuring the stable installation of the drive motor 40, and at the same time, ensuring that there is sufficient wind passing area between two adjacent adapter legs 32. Of course, in other embodiments, the size of the first section 321 can also be adaptively adjusted to other values ​​according to different needs.

[0058] Specifically, the thickness h of the first section 321 may be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc.

[0059] Specifically, in one embodiment, the angle between the first section 321 and the second section 322 is a, 140°≤a≤170°; the angle between the second section 322 and the front panel 10 is b, 140°≤b≤170°. In this way, after the drive motor 40 is installed on the motor frame 30, the stress between the second section 322 and the front panel 10 and the stress between the first section 321 and the second section 322 are not too large, which is beneficial to ensure the structural stability of the adapter leg 32 itself and the connection stability between the adapter leg 32 and the front panel 10, thereby reliably ensuring the stable support of the drive motor 40 by the motor frame 30.

[0060] In addition, the second section 322 can be parallel or substantially parallel to the front panel 10, so as to facilitate the avoidance and cooperation of the air outlet grille 20. Of course, in other embodiments, the angle can be adaptively adjusted to other values ​​according to different requirements.

[0061] Reference Figures 1 to 2 In one embodiment, the surface of the motor frame 30 facing the air outlet grille 20 is provided with a first reinforcement groove 33, and the first reinforcement groove 33 is formed in at least one of the fixing seat 31 and the adapter leg 32, so as to enhance the structural strength of the motor frame 30, thereby ensuring that the motor frame 30 reliably supports the drive motor 40 and the axial flow wind wheel 50, and at the same time, reducing the weight of the motor frame 30 to achieve a lightweight design. The first reinforcement groove 33 is recessed in the direction of the axial flow wind wheel 50.

[0062] Specifically, in order to ensure the structural strength of the fixing seat 31 and the adapter leg 32, in one embodiment, the fixing seat 31 and the adapter leg 32 are both provided with the above-mentioned first reinforcement groove 33. At this time, the first reinforcement groove 33 provided on the fixing seat 31 is configured as an annular groove, and the drive motor 40 is inserted into the inner ring side of the annular groove and connected to the groove bottom wall of the annular groove; the first reinforcement groove 33 provided on the adapter leg 32 is configured as a strip groove. It can be understood that the annular groove and the inner ring wall of the annular groove constitute a through hole for the drive motor 40 to be inserted and installed, which can increase the effective contact area between the drive motor 40 and the fixing seat 31 and improve the connection stability between the drive motor 40 and the fixing seat 31. A plurality of mounting feet are convexly provided on the outer periphery of the drive motor 40. When the drive motor 40 is partially inserted into the inner ring side, the mounting feet are placed on the surface of the groove bottom wall of the inner ring groove away from the air outlet mesh cover 20. The drive motor 40 can be installed on the fixing seat 31 by means of screw locking, buckling, etc. The strip groove extends along the extension direction of the adapter leg 32, and can partially extend to the connection between the adapter leg 32 and the front panel 10, and to the connection between the adapter leg 32 and the fixing base 31, further improving the structural strength of the motor frame 30, and improving the connection strength between the motor frame 30 and the front panel 10.

[0063] Reference Figure 4 In one embodiment, the outer contour of the motor frame 30 is provided with a plurality of flanges 34 extending in a direction away from the air outlet mesh cover 20. In this way, each flange 34 is arranged along the outer contour of the motor frame 30 to form a mounting groove opening toward the axial flow wind wheel 50, so as to further enhance the structural strength of the motor frame 30, thereby ensuring that the motor frame 30 reliably supports the drive motor 40 and the axial flow wind wheel 50, wherein the extension direction of each flange 34 may be parallel or approximately parallel to the axial direction of the air outlet 11.

[0064] To facilitate the installation of the drive motor 40 on the fixed seat 31, in one embodiment, a flange 34 connected to the periphery of the fixed seat 31 forms a housing cavity 35 for accommodating part of the drive motor 40. It can be understood that due to the provision of the first reinforcement groove 33, the bottom wall of the mounting groove protrudes toward the axial flow wind wheel 50 to form a mounting boss for installing the drive motor 40. Since the protruding height of the mounting boss is lower than the extending height of the flange 34, when the drive motor 40 is installed on the mounting boss, the flange 34 can limit the moving range of the drive motor 40 on the fixed seat 31, which helps to improve the installation efficiency of the drive motor 40 and the fixed seat 31. After the drive motor 40 is installed on the mounting boss, the flange 34 can cover the connection between the drive motor 40 and the fixed seat 31, which helps to ensure a reliable connection between the drive motor 40 and the fixed seat 31.

[0065] In one embodiment, the front panel 10 is provided with a second reinforcement groove 12, and the second reinforcement groove 12 is provided in plurality and arranged at intervals along the circumference of the air outlet 11, so as to enhance the structural strength of the front panel 10 and reduce the possibility of deformation of the air outlet 11; wherein, the second reinforcement groove 12 is provided in plurality and can be provided near the connection between the adapter leg 32 and the front panel 10, so as to enhance the connection reliability between the front panel 10 and the motor frame 30. In this embodiment, the second reinforcement groove 12 is provided with four and arranged along the diagonal direction of the front panel 10. In addition, the concave direction of the second reinforcement groove 12 can be set the same as the concave direction of the first reinforcement groove 33, so as to facilitate processing.

[0066] In one embodiment, the air outlet grille 20, the motor frame 30 and the drive motor 40 are correspondingly provided with connection holes 21 for fasteners to pass through and lock together, which helps to disperse the weight of the drive motor 40 and the axial flow wind wheel 50 to ensure the assembly stability of the drive motor 40 and the axial flow wind wheel 50.

[0067] Reference Figures 1 to 4 In one embodiment, the outdoor unit further includes a first air guide ring 61, which is integrally provided with the front panel 10 and can be integrally formed by stamping, thereby ensuring the processing efficiency and quality of the first air guide ring 61, and the waste generated by stamping the front panel 10 at the air outlet 11 can be reasonably utilized as the stamping material of the first air guide ring 61, thereby saving the cost of the first air guide ring 61 and saving the assembly process between the first air guide ring 61 and the front panel 10. Of course, in other embodiments, the first air guide ring 61 can also be integrally formed by casting or injection molding.

[0068] Specifically, the first air guide ring 61 includes a plurality of air guide plates 611 arranged at intervals, and the adapter leg 32 is arranged between two adjacent air guide plates 611, so as to facilitate the first air guide ring 61 and the motor frame 30 to be integrally stamped and formed on the front panel 10. At this time, the first reinforcement groove 33 formed at the connection between the adapter leg 32 and the front panel 10 is also arranged between two adjacent air guide plates 611.

[0069] In order to further ensure the diversion effect of the outdoor unit, Figures 5 to 6 As shown, in one embodiment, the outdoor unit also includes a second air guide ring 62 connected to the front panel 10, and the second air guide ring 62 is arranged on the inner side of the first air guide ring 61, and then the airflow is guided to flow outside the outdoor unit through the guide surface of the second air guide ring 62, thereby effectively improving the airflow guiding effect of the outdoor unit.

[0070] Specifically, the second air guide ring 62 is connected to a connecting foot 621, and an insertion groove 622 is formed between the connecting foot 621 and the outer wall of the second air guide ring 62. Part of the first air guide ring 61 is inserted into the insertion groove 622, that is, part of the first air guide ring 61 is sandwiched between the outer wall of the second air guide ring 62 and the connecting foot 621, so that the first air guide ring 61 and the second air guide ring 62 are connected as a whole, reducing the possibility of the second air guide ring 62 being separated from the front panel 10. The connecting foot 621 and the front panel 10 are correspondingly provided with mounting holes for fasteners to penetrate and lock together, further ensuring the stability of the connection between the second air guide ring 62 and the front panel 10. However, in other embodiments, other connection methods for fixing the second air guide ring 62 and the front panel 10 are also applicable to the present application, and are not limited here.
