The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] Reference below Figure 1-Figure 10 An air conditioner outdoor unit according to an embodiment of the present utility model is described.

[0044] According to the first aspect of the embodiment of the utility model, the air conditioner outdoor unit 100 includes: an outdoor casing 10, an outdoor heat exchanger 20, an air inlet mesh cover 30, an outdoor fan 40 and a motor bracket 50. The outdoor heat exchanger 20, the outdoor fan 40 and the motor bracket 50 are all arranged in the outdoor casing 10, and the motor bracket 50 is used to install and fix the outdoor fan 40.

[0045] The outdoor housing 10 is formed with an outdoor air inlet 11 and an outdoor air outlet 12. The outdoor air outlet 12 is located at the front side of the outdoor housing 10, and the outdoor heat exchanger 20 is arranged in the outdoor housing 10. The outdoor heat exchanger 20 can be arranged close to the outdoor air inlet 11, and the outdoor fan 40 can be located between the outdoor heat exchanger 20 and the outdoor air outlet 12. When the outdoor fan 40 is working, it can drive the external air to enter the outdoor housing 10 through the outdoor air inlet 11, exchange heat with the outdoor heat exchanger 20, and then be discharged from the outdoor air outlet 12, so that the heat or cold generated by the outdoor heat exchanger 20 can be taken away. By arranging the outdoor air outlet 12 at the front side of the outdoor housing 10, the exhaust of the outdoor housing 10 can be undisturbed, for example, by the interference of the building wall, and the exhaust effect is better.

[0046] For example, refer to Figure 7 At least a portion of the outdoor heat exchanger 20 is located on the rear side of the air-conditioning outdoor unit 100 , and the outdoor air inlet 11 is located on the rear side of the outdoor heat exchanger 20 .

[0047] For example, refer to Figure 7The outdoor heat exchanger 20 may be in an "L" shape, for example, the outdoor heat exchanger 20 includes a first heat exchange portion and a second heat exchange portion, the first heat exchange portion is located at the rear side of the outdoor fan 40, and the second heat exchange portion is located at the left side of the outdoor fan 40. By dividing the outdoor heat exchanger 20 into the first heat exchange portion and the second heat exchange portion, the area of ​​the outdoor heat exchanger 20 can be increased, and the heat exchange efficiency of the outdoor heat exchanger 20 can be increased.

[0048] For example, the outdoor housing 10 may include a chassis 13, a top cover 14, a side panel and a front panel, the top cover 14 is arranged above the chassis 13 and is spaced apart from the chassis 13 in the up and down direction, the side panels are connected to the left and right sides of the chassis 13, the bottom of the side panels is connected to the chassis 13, the top of the side panels is connected to the top cover 14, and the front panel is arranged on the front side of the side panels and connected to the side panels. Among them, the outdoor air inlet 11 may be formed on the rear side and the side panel of the outdoor housing 10, the outdoor air outlet 12 may be formed on the front panel, and the outdoor air outlet 12 may be covered with an air outlet net cover to reduce foreign objects such as mosquitoes from entering the air conditioner outdoor unit 100. Among them, the outdoor heat exchanger 20 may be "L" shaped, for example, the outdoor heat exchanger 20 includes a first heat exchange part and a second heat exchange part, the first heat exchange part is located at the rear side of the outdoor fan 40, and the second heat exchange part is located on the left side of the outdoor fan 40.

[0049] The air inlet grille 30 is installed on the outdoor housing 10. The air inlet grille 30 can be installed at the outdoor air inlet 11 to reduce foreign objects such as mosquitoes from entering the outdoor housing 10. The air inlet grille 30 includes a grille body 31 and a bracket plate 32 connected to each other. The grille body 31 is located between the outdoor air inlet 11 and the outdoor heat exchanger 20. The air entering from the outdoor air inlet 11 can pass through the grille body 31 and then enter the outdoor housing 10, and then exchange heat with the outdoor heat exchanger 20, and drive the outdoor fan 40 to flow toward the outdoor air outlet 12, and be discharged through the outdoor air outlet 12. The bracket plate 32 is located on the upper side of the outdoor heat exchanger 20. The bracket plate 32 can be supported on the upper side of the outdoor heat exchanger 20. The left and right ends of the grille body 31 can be connected to the side plates, so that the installation of the air inlet grille 30 is stable.

[0050] For example, refer to Figure 2 The outdoor housing 10 includes a top cover 14, wherein the top cover 14 may be a sheet metal part, and the bracket plate 32 is located on the upper side of the outdoor heat exchanger 20 and at least partially covers the top of the outdoor heat exchanger 20. At this time, the portion of the bracket plate 32 covering the top of the outdoor heat exchanger 20 may serve as a portion of the top cover 14. By making the bracket plate 32 located on the upper side of the outdoor heat exchanger 20 and at least partially covering the air conditioner outdoor unit 100, the portion of the bracket plate 32 covering the top of the outdoor heat exchanger 20 may serve as a portion of the top cover 14.

[0051] The outdoor fan 40 is arranged on one side of the outdoor heat exchanger 20 close to the outdoor air outlet 12. The outdoor fan 40 and the outdoor air outlet 12 can be arranged opposite to each other in the front-to-back direction. The outdoor fan 40 includes an outdoor wind wheel 41 and an outdoor motor 42. The outdoor wind wheel 41 can be an axial flow wind wheel. The rotation axis of the outdoor wind wheel 41 can extend in the front-to-back direction. The outdoor motor 42 is connected to the outdoor wind wheel 41 to drive the outdoor wind wheel 41 to rotate. The outdoor motor 42 drives the outdoor wind wheel 41 to rotate, so that the external air can enter the outdoor housing 10 from the outdoor air inlet 11, and be discharged to the external environment from the outdoor air outlet 12 after heat exchange with the outdoor heat exchanger 20.

[0052] The motor bracket 50 is used to install the motor, and the motor bracket 50 is arranged in the outdoor housing 10. The motor bracket 50 includes a bracket body 51, a first connecting plate 52, and a second connecting plate 53. The first connecting plate 52 and the second connecting plate 53 are respectively connected to the upper and lower ends of the bracket body 51. The first connecting plate 52 is connected to the lower end of the bracket body 51, and the second connecting plate 53 is connected to the upper end of the bracket body 51. The outdoor motor 42 is installed on the bracket body 51, and the first connecting plate 52 is connected to the chassis 13 of the outdoor housing 10. The motor bracket 50 is fixed to the chassis 13 through the first connecting plate 52.

[0053] Optionally, a mounting hole 63 is provided on the bracket body 51 for connecting the motor bracket 50 to the motor.

[0054] The second connecting plate 53 is located on the upper side of the bracket plate 32, and the second connecting plate 53 is connected to the bracket plate 32 and the top cover 14 of the outdoor housing 10. By making the motor bracket 50 include the second connecting plate 53, and the second connecting plate 53 is located on the upper side of the bracket plate 32, the motor bracket 50 can be separated from the outdoor heat exchanger 20, and the motor bracket 50 does not contact the outdoor heat exchanger 20, so that the two will not vibrate and rub against each other to generate noise.

[0055] By locating the second connecting plate 53 on the upper side of the bracket plate 32 and connecting it to both the bracket plate 32 and the top cover 14 of the outdoor casing 10, the second connecting plate 53 can be fixed relative to the bracket plate 32 and the top cover 14 of the outdoor casing 10, thereby reducing the friction between the second connecting plate 53 and the bracket plate 32, and reducing the friction between the second connecting plate 53 and the top cover 14, thereby avoiding the noise generated by the friction between the motor bracket 50 and the top cover 14; and, by connecting the second connecting plate 53 to the bracket plate 32 of the air inlet mesh cover 30 and the top cover 14 of the outdoor casing 10, the connection of the second connecting plate 53 can be made more stable.

[0056] In addition, by providing a second connecting plate 53 at the upper end of the motor bracket 50 and connecting the second connecting plate 53 to the bracket plate 32 and the top cover 14 of the outdoor casing 10, the motor bracket 50 can be prevented from tipping forward due to the force of the motor, making the motor bracket 50 more stable, thereby making the operation of the outdoor fan 40 more stable.

[0057] According to the air-conditioning outdoor unit 100 of the embodiment of the utility model, the motor bracket 50 is provided with a second connecting plate 53, and the second connecting plate 53 is located on the upper side of the bracket plate 32, so that the second connecting plate 53 is spaced apart from the outdoor heat exchanger 20, so as to avoid the second connecting plate 53 of the motor bracket 50 and the outdoor heat exchanger 20 from rubbing against each other and generating noise; and the second connecting plate 53 is connected to the top cover 14, so that the second connecting plate 53 is fixed relative to the top cover 14, which can reduce the noise generated by the mutual friction between the second connecting plate 53 of the motor bracket 50 and the top cover 14; in addition, the second connecting plate 53 of the motor bracket 50 is connected to the bracket plate 32 of the air inlet mesh cover 30 and the top cover 14 of the outdoor casing 10, which can improve the stability of the connection and fixation of the second connecting plate 53.

[0058] According to some embodiments of the present invention, reference Figure 4 The second connecting plate 53 is connected and fixed to the bracket plate 32 and the top cover 14 by fasteners 70. The second connecting plate 53 is connected and fixed to the bracket plate 32 by fasteners 70. The second connecting plate 53 is connected and fixed to the top cover 14 by fasteners 70. By using fasteners 70 to connect and fix the second connecting plate 53 to the bracket plate 32 and the top cover 14, it can be ensured that the connection between the second connecting plate 53, the bracket plate 32 and the top cover 14 is more stable without relative movement, and the noise caused by friction between the second connecting plate 53 and the bracket plate 32 or the top cover 14 is further reduced.

[0059] According to some embodiments of the present invention, reference Figure 4, the fastener 70 is passed through the top cover 14, the second connecting plate 53 and the bracket plate 32 to connect the second connecting plate 53 with the bracket plate 32 and the top cover 14. For example, a first connecting hole is provided on the top cover 14, a second connecting hole is provided on the second connecting plate 53, and a third connecting hole is provided on the bracket plate 32. The fastener 70, such as a screw, can be passed through the first connecting hole, the second connecting hole and the third connecting hole from top to bottom in sequence, so that the top cover 14, the second connecting plate 53 and the bracket plate 32 can be connected and fixed. By allowing the fastener 70 to pass through the top cover 14, the second connecting plate 53 and the bracket plate 32, the fastener 70 can connect the three components of the top cover 14, the second connecting plate 53 and the bracket plate 32 together, saving the number of fasteners 70, reducing the number of openings on the top cover 14, the second connecting plate 53 and the bracket plate 32, and improving the assembly connection efficiency.

[0060] According to some embodiments of the present invention, reference Figure 4 The bracket plate 32 is formed with a limiting protrusion 33 protruding upward, and the second connecting plate 53 is formed with a limiting groove 54 opening downward, and the limiting protrusion 33 is accommodated in the limiting groove 54. When installing the motor bracket 50, the upper end of the motor bracket 50 can be connected and fixed first, so that the second connecting plate 53 at the upper end of the motor bracket 50 is located on the upper side of the bracket plate 32 of the air inlet mesh cover 30, and the second connecting plate 53 is pressed downward to accommodate the limiting protrusion 33 in the limiting groove. At this time, the side wall of the limiting protrusion 33 abuts against the side wall of the limiting groove, so that the motor bracket 50 can be limited and will not fall forward, and the pre-positioning installation of the motor bracket 50 can be realized, which is convenient for further connection and fixation.

[0061] Then, the first connecting plate 52 at the lower end of the motor bracket 50 can be connected to the chassis 13, for example, by fasteners 70 to connect and fix the first connecting plate 52 to the chassis 13, and further, the second connecting plate 53 can be connected and fixed to the top cover 14 and the bracket plate 32 by fasteners 70. By providing a limiting protrusion 33 on the bracket plate 32, and making the limiting protrusion 33 cooperate with the limiting groove 54 on the second connecting plate 53, the motor bracket 50 can be tilted forward during the installation process, making the installation process of the motor bracket 50 more convenient.

[0062] According to some embodiments of the present invention, reference Figure 4The limiting groove 54 includes a first limiting wall 55 and a second limiting wall 56, which are arranged opposite to each other in the front-to-back direction, and are respectively located at the front and rear sides of the limiting protrusion 33, the first limiting wall 55 is located at the rear side of the limiting protrusion 33, the first limiting wall 55 extends in the vertical direction, the second limiting wall 56 is located at the front side of the limiting protrusion 33, and the second limiting wall 56 extends obliquely toward the front in the direction from top to bottom. By making the second limiting wall 56 extend obliquely toward the front in the direction from top to bottom, the opening of the limiting groove 54 can be made larger, and when the motor bracket 50 is installed, the limiting protrusion 33 can be easily accommodated in the limiting groove 54, which can reduce the difficulty of installation. Furthermore, by setting the first limiting wall 55 located on the rear side to extend in the vertical direction, the limiting groove 54 can have a better backward supporting force for the limiting protrusion 33, thereby better reducing the forward tilting of the motor bracket 50 during the installation process, and can also better prevent the motor bracket 50 from tilting forward after the motor is installed on the motor bracket 50.

[0063] According to some embodiments of the present invention, reference Figure 4 , the size of the first limiting wall 55 in the vertical direction is greater than the size of the second limiting wall 56 in the vertical direction. The motor bracket 50 has a tendency to tip forward under the action of the force of the motor, and the first limiting wall 55 abuts against the limiting protrusion 33, which can prevent the motor bracket 50 from tipping forward. By making the size of the first limiting wall 55 in the vertical direction greater than the size of the second limiting wall 56 in the vertical direction, the abutment area between the first limiting wall 55 and the limiting protrusion 33 can be made larger, so that the limiting effect of the first limiting wall 55 is more sufficient, and the motor bracket 50 can be better prevented from tipping forward, and the stability of the motor bracket 50 can be fully guaranteed.

[0064] According to some embodiments of the present invention, reference Figure 5 and Figure 7 The limiting protrusion 33 is in the shape of a long strip extending in the left-right direction, and the limiting groove 54 extends in the left-right direction. By making the limiting protrusion 33 in the shape of a long strip extending in the left-right direction, correspondingly, the limiting groove 54 extends in the left-right direction, the contact area when the limiting protrusion 33 and the limiting groove 54 cooperate can be increased, and the cooperation length in the left-right direction can be increased, so that the limiting protrusion 33 and the limiting groove 54 are more fully limited, and the stability of the motor bracket 50 can be ensured.

[0065] According to some embodiments of the present invention, reference Figure 4 and Figure 8The second connecting plate 53 includes a first plate portion 57 and a second plate portion 58 connected to the rear side of the first plate portion 57, the first plate portion 57 forms a limiting groove 54, and the second plate portion 58 is connected to the bracket plate 32 and the top cover 14 through a fastener 70. By dividing the second connecting plate 53 into the first plate portion 57 and the second plate portion 58, and the first plate portion 57 forms the limiting groove 54, and the second plate portion 58 is connected to the bracket plate 32 and the top cover 14 through a fastener 70, the second plate portion 58 connected to the fastener 70 on the second connecting plate 53 and the first plate portion 57 forming the limiting groove 54 can be separated, so as to avoid the second connecting plate 53 being connected to the fastener 70, the fastener 70 and the first plate portion 57 interfering with each other, and affecting the limiting effect of the limiting groove 54; and it can also avoid the top cover 14 or the bracket plate 32 interfering with the first plate portion 57, which leads to difficulty in installation and fixing.

[0066] According to some embodiments of the present invention, reference Figure 4 The upper surface of the bracket plate 32 is formed with a mounting groove 34, and the second plate portion 58 is accommodated in the mounting groove 34. By accommodating the second plate portion 58 in the mounting groove 34, the mounting groove 34 can limit the motor bracket 50, thereby preventing the motor bracket 50 from moving backward or left and right to interfere with other components, and ensuring that the position of the motor bracket 50 is more fixed; and the mounting groove 34 can also provide a position prompt when the user is installing, so that the user can more easily install the motor bracket 50 to the correct position.

[0067] According to some embodiments of the present invention, reference Figure 5 and Figure 7The upper surface of the bracket plate 32 is formed with a sealing rib 35 extending in the left-right direction, and the sealing rib 35 is connected to the left and right sides of the limiting protrusion 33. The top cover 14 includes a top cover 14 body and a connecting flange 16 formed on the rear side of the top cover 14 body. The top cover 14 body is located in front of the sealing rib 35 and the top cover 14 body abuts against the sealing rib 35. The airflow entering the casing from between the top cover 14 and the bracket plate 32 may be directly blown out by the fan without passing through the heat exchanger, resulting in a decrease in the heat exchange efficiency of the air conditioner outdoor unit 100.
